Description

Description of the invention

This application is separated from the application Mo98020820, which is the national phase of the International application PCT/О596/13362 2 dated 08/16/96. with priority from 17.08.1995

The present invention relates to a method of cutting and processing vegetation with a processing liquid of plant stems remaining after trimming.

Power companies periodically trim vegetation that grows along power lines in right-of-way to maintain access to power lines and minimize grid losses. Access is required 70 to facilitate maintenance and repair of damaged lines. Excessive network losses can occur when tall and dense vegetation under power lines causes electric current to leak into the ground. The higher and denser the vegetation, the higher the loss in the line due to side radiation. Road authorities also periodically trim plants that grow in the middle and along the sides of roads to ensure the safety of drivers and pedestrians. Cutting vegetation improves visibility and creates 712 areas along roads for emergency stops. As the need for power lines and roads increases, the length of right-of-way and roadsides increases exponentially. Accordingly, electric companies and road authorities are constantly finding more efficient and economical ways to cut vegetation along the right-of-way and roadsides.

Power companies and road agencies have found it beneficial to treat plants with special substances during cutting to limit the growth of unwanted vegetation or to slow down the growth rate of desirable vegetation. Vegetation is usually treated with granular or liquid substances such as growth regulators, herbicides, pesticides, fungicides, fertilizers or biological agents, depending on the desired result. Treatment with liquids is most often done by spraying in the air, so that the liquid contacts the vegetation and is retained by absorption of the liquid into individual plants. with

Common methods of spreading fluids include spraying the treatment fluid into the area containing plants from aerial vehicles, from ground vehicles equipped with spray nozzles, from hand-held sprayers, or using mowers equipped with treatment devices. However, until now there were no mowers with processing devices that could cut vegetation and process it in a non-horizontal direction, for example, on the slopes of hills, with the attachment of the mower head to the end of the articulated outrigger. with

Unfortunately, these methods of distribution do not ensure the accuracy of distribution or regulation of the amount of liquid that reaches the plants. Methods of distribution, in particular, spraying, allow the treatment substance to get not only on the plants to be treated, but also in other places. If the treatment is carried out through the air, the spray density is reduced and some plants may not be treated at all. In addition, if the concentration of the treatment substance is high, the operator usually spreads more substance than necessary, and thus large amounts of substance are wasted unproductively. Treatment liquids are usually sprayed until the leaves of the plants become visibly wet. At the same time, it is impossible to predict how much of the processing substance will fall on the ground around the plants and pollute the surrounding soil and underground water system, and how much of the processing substance will be absorbed into the vascular, or evaporative, system of the plants, on which it should have the desired effect. with Bom'Eiapso, a herbicide manufacturer, warns consumers that its liquid chemicals are only effective in

If the substance penetrates the leaves and is absorbed into the evaporative system of the plant. That's why chemical companies produce chemicals known as "adjuvants" that help spray liquids penetrate through the dense leaf sheath. Many processing liquids also contain surface-active substances that promote the absorption of the agent into the evaporative system of the plant. However, of course, only a small part of the liquid that is sprayed really gets into the plant's evaporation system. Another part of the chemical liquid settles on the ground, from where

Ge"), when mixed with precipitation, it can spread to the surrounding areas or evaporate into the atmosphere and then be blown away by the wind. o Naturally, farmers and those people who live near power lines and highways o 20 object to such applications of treatment fluids that lead to their spreading or dispersal. Therefore, government laws and municipal ordinances in many cases restrict electric companies and road agencies from distributing treatment fluids by spraying. And although electric companies and road agencies strictly obey these laws and regulations, ecologists believe that with any method of distribution of treatment fluids, they inevitably contaminate the soil and the underground water 25 system, and there is also a risk of their being washed away and carried away by the wind. In addition, in the event that it happened

GF) chemical contamination of land or water near the processing area, electric companies and road agencies cannot provide convincing evidence that the operation of cutting and processing plants was not the source of contamination. o There are various devices for cutting and treating vegetation with special liquids. For example, in patents

USA Mo. 2,908,444 and 2,939,636, publ. 13.10.59 and 07.06.60, respectively, by Mullen; US patent Mo. bo 2,973,615, publ. 07.03.61, author Yaremchuk; US patent Mo. 3,332,221, publ. 07/25/67, by McCain, described rotary lawn mowers equipped with a sprayer for liquid chemicals. In US patent Mo. 5,237,803, publ. 08/24/93 by Domingue describes a trailed mower (with horizontally rotating blades) or betwing type mower equipped with sprayers for liquid chemicals. Sprayers are located above the blades inside the mower in such a way that sprays of processing fluid are distributed strictly within the area that is under the body as the mower moves on the ground. The liquid is dispersed by the centrifugal force created by the rotation, or released over the mower blade, so that some of the liquid evaporates as it collides with the body and/or the rotating mower blade. However, the treatment liquid can get on the ground around the plants, and the evaporating liquid can be carried by the wind into the environment. In addition, none of these devices can cut and process vegetation in a non-horizontal position, for example, from the end of an articulated boom.

In US patent Mo. 2,878,633, publ. 03/24/59, by Mullen, and US Patent Mo. 3,090,187, publ. 05/21/63, by Livingston, described rotary lawn mowers equipped with a device for feeding the treating fluid to the rotating mower blade. Mullen's patent further describes a piping device for supplying 70 treating fluid to an internal channel located along the axis of the rotating mower shaft and terminating in an opening in the lower part of the blade. However, the centrifugal force of the rotating blade ejects the processing liquid from the hole in the form of drops. The Livingstone patent also describes a longitudinal groove in the leading edge of the blade to feed the processing fluid to the lower part of the blade tip. Thanks to this, the processing liquid is supplied directly to the freshly cut stem of the plant. However, the switchgear /5 of the Livingston Mower is open to the atmosphere. Thus, the processing liquid can spill on the ground or evaporate and be carried by the wind to the surrounding areas.

In US patent Mo. 4,926,622, publ. 05/22/90, author Makka, describes a rotary cutter for clearing bushes and an applicator for applying herbicides. The cutter includes a plurality of cutting blades, and the applicator includes means for feeding the herbicide to the cutting blades so that the herbicide is applied to the shrub as it is cut by its rotating blades. In one embodiment, the applicator, in addition, includes a closed pipeline for transferring the processing liquid from the container installed on top of the body of the rotary cutter to the outlet next to the blade. The pipeline includes an elongated tube attached to the outer surface of the rotating blade so that the outlet is in fluid communication with the axial shaft of the rotary cutter. However, the pipe may crack or bend when the blade is bent longitudinally, and may suffer punctures or tears if the blade suddenly strikes a stationary rock or stump.

As can be seen from the disadvantages of the above-described rotary mowers, for cutting vegetation and processing cut i) vegetation with a special liquid, a device and a method are needed in which the processing liquid does not spread to the surrounding land or into the atmosphere. In accordance with this, the task of this invention is to create a method of cutting vegetation with simultaneous processing of stems of cut vegetation that remain without Ge! from spreading the processing liquid on the surrounding ground or into the atmosphere.

The next task of the invention is to create a method of cutting and simultaneous processing of the stems of the trimmed vegetation that remain, in which the supply of the processing liquid to the lower part of the cutting blade c is carried out in such a way that the flow of the processing liquid continuously flows to the stems of the plants that remain. ise)

The next task of the invention is to create a method of cutting and simultaneous processing of the stems of the cut vegetation that remain, so that the processing liquid enters directly into the evaporation system of the plants.

The next task of the invention is to create a method of cutting vegetation and simultaneously processing the stalks of cut vegetation that remain, suitable for use regardless of the horizontal location of the blade relative to the liquid container. The next task of the invention is to create a method for cutting and simultaneously processing vegetation. with a special liquid that minimizes spillage, unproductive consumption and spoilage of the processing liquid. and The next task of the invention consists in creating a method of cutting vegetation and simultaneously applying a strictly defined amount of processing liquid to the stem of the cut plants that remain.

The next task of the invention is to create a method of cutting and simultaneous processing of vegetation

Ge" in which the amount of processing liquid supplied to the cutting blade is precisely measured.

The invention consists in a method of cutting vegetation and simultaneously processing the stems of trimmed plants, which

Me. remain, processing liquids, such as growth regulators, herbicides, pesticides, fungicides, fertilizers, adjuvants, surface-active or biological agents, preferably water-based. The treatment liquid is applied without spreading, such as spraying, the treatment substance to the surrounding soil or into the atmosphere. Instead, the treatment fluid is supplied from a hermetically sealed fluid reservoir through

Ge fluid pipeline to the lower part of the cutting blade in a continuous flow. In this way, the treatment fluid is continuously supplied to the cut ends of the stems remaining at the time of cutting, so that at least about 75-9595 of the treatment fluid is absorbed directly into the evaporative system of the plants, and almost

Immediately, which gives maximum processing efficiency and significantly reduces the need for processing liquid, as well as the amount of active ingredient. (F, The method is carried out with the help of a device that includes a mower, a cutting blade drive for rotation of a trimming and processing device, which includes at least one cutting blade assembly, installed with the possibility of rotation on a blade holder, a container for processing liquid, a device for measuring the amount of processing fluid supplied to the trimming and processing device, as well as a liquid pipeline for supplying the processing fluid from the container for the liquid to the trimming and processing device.

A lawnmower can be any manoeuvrable tool for cutting vegetation, moving on or above the ground, such as a tool for trimming hedges, trees and orchards. For example, 65 Mower may be a push mower, a conventional electric lawn mower, a horse-driven lawn mower, a tractor-powered mower, a trailed mower (with horizontally rotating blades)

or betwing mower, harvester, hydraulic baler, high-speed saw attachment, high-speed secateur attachment, knife blade, multi-disc mower, drum mower, chain mower, or mower head attached to an articulated outrigger. The mower, described here as an example only, is a conventional trailed mower attached to the back of a farm tractor.

The mower preferably includes a generally flat deck having a central opening to accommodate the cutting blade drive, a pair of generally straight opposing ends, a generally straight front wall, and an arcuate rear wall.

At a minimum, a portion of the rear wall may include a plurality of short chain lengths to prevent 7/0 Throwing solid pieces, such as rocks, from under the mower deck. The mower is equipped with at least one wheel attached to the mower deck to facilitate movement on the ground and to maintain the cutting and processing attachment at the desired height above the ground. A set of vertical racks are attached to the upper surface of the deck, between which the container for the liquid is held.

The cutting blade drive is attached to the mower deck and includes an oblong drive shaft located 7/5 Inside the central opening of the mower deck. The drive of the cutting blade mainly works from the power take-off box of the tractor that drives the mower. However, the cutting blade drive can be powered by a gasoline engine or a hydraulic motor mounted on top of the mower deck. In the preferred embodiment, a bevel gear is installed at one end of the drive shaft for engagement with the shaft of the rotating selection box of tractor power. The trimming and processing device is attached to the other end of the drive shaft. The cutting blade drive independently rotates the cutting blade drive drive shaft, which in turn rotates the blade holder and at least one cutting blade assembly of the trimming and processing device. The drive shaft of the drive of the cutting blade internally contains a pipeline for the through-flow of fluid, so that the drive shaft of the drive of the cutting blade is in fluid connection with the pumping device and the trimming and processing device. high school

The trimming and processing device is attached to the drive shaft of the cutting blade drive directly at the lower surface of the mower deck and includes at least one cutting blade assembly, i) mounted rotatably on the blade holder. To attach at least one cutting blade assembly, the blade holder can have any shape. In the preferred embodiment, the blade holder is an oblong plate having a central hole for placing the cutting blade drive in it and at least one hole at the end of the plate for placing the cutting blade assembly in it. Between the central hole and the hole at the end of the plate there is a longitudinal liquid pipeline. The fluid pipeline provides a through passage of fluid so that the drive shaft of the cutting blade is in fluid communication with the cutting blade assembly. In another preferred embodiment, the blade holder is a generally flat disk on which a plurality, preferably four, orthogonally placed assembly of cutting blades. ise)

At the end of the blade holder, at least one cutting blade assembly is installed with the possibility of rotation. The node "o" of the cutting blade is preferably installed at each of the opposite ends of the blade holder. The cutting blade assembly includes a cutting blade shaft and a cutting blade sleeve fixed to the cutting blade shaft. The cutting blade sleeve carries the cutting blade outwardly from it. The lower part of the bushing is made in the shape of a saucer, so that if the bushing hits an obstacle on the ground in the direction of the cutting blade, the bushing passes through the obstacle without transmitting the impact to the cutting blade. The front edge of the cutting blade is beveled to form a sharp cutting edge. The cutting blade assembly has a liquid pipeline inside, which provides a through

And the passage of liquid, so that the liquid pipeline located in the blade holder is in liquid connection with the lower part of the cutting blade.

The fluid container is secured between uprights mounted on top of the mower deck. The liquid container includes at least one substantially hollow, hermetically sealed liquid reservoir containing the processing liquid. In a preferred embodiment, the container includes a plurality of cross-stacked, removable, fluid reservoirs that are connected. Each of the tanks is made of material,

Me, resistant to ultraviolet radiation, such as polyurethane, polyethylene or polyvinyl chloride (PVC) or plastic.

Each tank contains inlet and outlet ports that connect to the encompassing parts of a double-co shut-off fitting. The encompassing part of the fitting is connected to the encompassing part of the fitting and

He allows the flow of processing liquid from the upper tank to the lower one, and from the lower one to the transition fitting adjacent to the pumping device. A flexible fluid pipe connects the outlet of each upper tank to the inlet of the next lower tank. A flexible liquid pipe, which comes from the outlet of the lowermost tank, passes through the pumping device and connects to the fitting on the housing of the cutting blade drive. Thus, the fluid reservoir is in the fluid (F) connection to the cutting blade drive. The encompassing fitting portion, which fits into the encompassing portion of the fitting in the inlet of the uppermost tank, connects to the through-line filter and the vent valve cap. for connecting liquid reservoirs with the surrounding atmosphere.The filter prevents stones, insects, etc. from entering the system, but does not limit the supply of ambient air.

The tanks are packaged so that the lowest tank is automatically filled with treatment fluid from the upper tanks as the treatment fluid is applied to the vegetation being trimmed.

Reservoirs in any quantity are filled elsewhere, therefore liquid spillage at the workplace where it can affect workers, contaminate the surrounding soil or the underground system 65 Water supply is excluded. The tanks are hermetically sealed, so that the processing liquid cannot spoil or lose its properties. Pre-filled tanks in a predetermined quantity can be stacked so that the user does not have to interrupt trimming and processing to refill tanks or replace empty tanks. Empty tanks are returned to the appropriate service for refilling, without the need for on-site rinsing, and are never disposed of in municipal landfills.

Flow control devices measure the amount of processing fluid supplied by the pump device to the lower part of the cutting blade. The flow control means include a control unit electrically connected to a ground speed sensing device. The device for determining the speed relative to the ground includes a sensitive element for determining the angular speed of the rear wheel of the tractor and the speed of the mower, which is calculated from it. In the preferred embodiment, the speed detection device is located in 7/0 of each of the rear wheels of the tractor, then the angular speed of the rear wheels is averaged and multiplied by a correction factor, in order to more accurately calculate the speed of the tractor relative to the ground. The control unit is also electrically connected to a DC stepper motor that drives the pumping device so that the desired amount of treatment fluid is applied to the vegetation in the area being treated.

The flow control means provide a continuous flow of fluid so that the fluid reservoir /5 is in fluid communication with the cutting blade assembly of the trimming and processing device. The flow control means includes a flexible tube laid between the outlet of the lowermost fluid reservoir and the fluid fitting on the cutting blade drive housing. A through passage for the fluid is provided by the fluid tube of the cutting blade drive, the blade holder and the cutting blade assembly. Thus, the piping system provides a through passage for supplying the treatment liquid to the lower part of the cutting head, so that the treatment liquid continuously flows to the stems of the plants that remain at the time of their cutting.

Figures 1 and 2 show a device marked with the general position 40 for cutting vegetation and simultaneously treating the stems of the cut plants that remain with a special liquid. The treatment liquid can be any liquid applied to vegetation, including a growth regulator, 2o herbicide, pesticide, fungicide, fertilizer or biological agent, depending on the desired result. The processing liquid is preferably water-based. However, the base of the processing liquid can be any substance that mixes with the processing liquid to form a non-viscous fluid. The device 40 supplies the processing liquid to the lower part of the cutting blade, so that the flow of the processing liquid constantly flows to the stem of the trimmed plants that remain at the time of their cutting. It was discovered that the following physical phenomenon occurs when plants are cut. The remaining liquid near the cut end of the stem is drawn into the plant's evaporative system almost immediately and migrates through the evaporative system into the plant's root system. This phenomenon was named and is referred to here as the "Burch effect".

The discovery of the Burch effect led to the development of a device and a method called the "VOXN MET" system

VGAOEtm" (system of "wetted Burch blade"), which take advantage of the Burch effect to minimize Ge!

From The amount of treatment fluid required to treat vegetation and to maximize treatment efficiency.

In particular, the "wetted Burch blade" system does not use the spreading of the processing fluid, such as co-spraying or the processing and spreading of the processed cut residues on the surrounding land by wind. At least about 75-95956 of the processing liquid, which constantly enters the plants at the time of their cutting, is absorbed into the evaporative system of the stems of the remaining plants. Thus, it is practically excluded,

Зз5 unproductive flow of liquid, accidental spillage of liquid on other plants, as well as pollution of the surrounding soil and underground water system.

The "wetted Burch blade" system may have a configuration suitable for use with any device 40 having at least one cutting blade and means for supplying a continuous flow of processing fluid to the underside of the cutting blade. For example, the device 40 can be a push mower, a conventional electric mower, a horse-driven mower, a tractor-powered mower, a trailed mower (with horizontally rotating blades), or a betwing mower, a mower, a hydraulic and roller mower. - a baler, high-speed saw attachment, high-speed secateur attachment, knife "" plate, multi-disc mower, drum mower, chain mower or mower head attached to an articulated outrigger, unless the mower is equipped with suitable means for supplying a continuous flow of processing fluid to cut vegetation. In addition to cutting and processing plants along

Gee! right-of-way and medians and highway shoulders, there are a large number of other vegetation care tasks, such as agricultural, turf, ornamental, forestry and water management, where the use of a non-spraying device and method of cutting and processing vegetation is useful, profitable and practical, including ) the use of biological agents that are introduced directly into the internal evaporative system of plants in order to reduce the probability of the substance entering the environment and increase its efficiency. for For purposes of clarity, Fig. 1 represents a three-dimensional image of an electric lawnmower 41, equipped

Ge) by the "wetted Burch blade" system. Fig. 2 is a three-dimensional view of a trailed mower 42 equipped with a "wetted Burch blade" system and attached to a tractor 43. The trailed mower 42 is shown here only to illustrate preferred variants of the "wetted Burch blade" system. As indicated above, the "wetted Burch blade" system can be used with any device 40 to cut vegetation and simultaneously treat the trimmed vegetation with a treatment liquid, as well as for many other vegetation care tasks. iF) Fig. 3 is a block diagram of the main components of the "wetted Burch blade" system. Preferably, the trailed mower 42 is powered by a conventional power take-off 44 of the tractor 43. The power take-off 44 is connected to a cutting blade drive 60, which actuates the trimming and processing device 90. The fluid container 130 contains a plurality of processing fluids. tightly closed tanks, as described above. The pumping device 150 pumps the processing fluid from the fluid reservoir 130 through the cutting blade drive 60 to the trimming and processing device 90. A flow control means 160 may be installed to measure the amount of processing fluid that is supplied by the pumping device 150 to the trimming and processing device 90. Piping device 190 provides a through passage for b5 supply of the processing liquid from the container for the liquid 130 to the trimming and processing device 90.

The pipe is small enough in diameter, so that the passage is constantly filled with processing fluid regardless of the speed of the mower relative to the ground under normal operating conditions. Thus, the piping device 190 provides a continuous flow of the treatment liquid at a variable specific flow, as a result of which a constant volume of the treatment liquid, usually measured in liters/ha, is applied to the treated area 1 at the time

As the fluid passage remains always filled. In particular, the means of regulating the flow provide a continuous flow of the processing liquid to the treated area in the amount of less than 300 ml/ha, preferably 12-300 ml/ha. Such a low consumption of processing liquid is achieved due to the Burch effect and cannot be achieved with the help of any other known systems of liquid processing of plants.

Fig.4 is an enlarged three-dimensional image of the trailed mower 42. The trailed mower 42 can be 70 any trailed mower. The trailed mower 42, which is shown in the picture, is a model A-72 manufactured by AIato Ipdyzig! of Zediup, Texas, modified for equipment with a "moistened blade" system

Burcha". The cutting blade drive 60 of the trailed mower 42 receives power from the power take-off box 44 of the tractor 43. The power take-off box 44 may include a drive shaft (not shown) that rotates connected to the cutting blade drive 60, as will be described below, to rotate the trimming and processing 7/5 attachment 90 at a cutting blade end speed of about 3,600 to 5,700 m/min.Thus, each cutting blade of the mower 42 can reach a speed of about 320 km per hour.

The trailed mower 42 includes a mower deck 50, to which the cutting blade drive 60 and the body of the trimming and processing device 90 are attached. The fluid container 130 and the pumping device 150 are preferably installed on the mower deck 50, but may also be installed on the tractor 43. Flow control means 160 2o piping system 190 are installed on the deck of the mower 50 and, if necessary, on the tractor 43. One end of the connection system 45 is attached to the deck of the mower 50 and the other end to the tractor 43, so that the tractor can carry the mower 42 behind it .

The mower deck 50 can be of any size and shape necessary to accommodate the blade drive 60 and the cutting and processing device housing 90. As shown in the figure, the mower deck 50 includes a generally flat horizontal upper surface 51, a generally flat horizontal lower surface 52 opposite the upper surface 51, a pair of opposite, generally flat, end faces 53 extending vertically downward from the upper i) surface 51, a generally flat front wall 54 extending vertically downward from the upper surface 51, and an arched rear wall 55 extending vertically downward from the upper surface 51. The horizontal lower surface 52 and the vertically located ends 53, the front wall 54 and the back wall 55 will form a solid body that Ge! zo Covers the trimming and processing device 90. The rear wall 55 preferably includes a plurality of guard chains 56 to prevent large objects such as rocks from being thrown backwards from under the mower. A second set of safety chains 56 is suspended from the lower surface 52 to prevent large objects from being thrown forward from under the mower.

The mower deck 50 has a central opening 57 to accommodate the cutting blade drive 60, as will be described hereinafter. At least one and preferably two wheels 58 are attached to the upper surface 51 of the deck of the mower 50 to support the cutting blades of the mower 42 at a convenient height above the ground. The wheels 58 are preferably adjustable so that the elevation of the mower deck 50 and thus the distance from the cutting blades to the ground can be varied. The deck of the mower 50, as described earlier, is a conventional deck of a trailed mower and can be replaced by any other deck adapted to install the drive of the cutting blades 60 and the housing of the trimming and processing device 90. c The drive of the cutting blades 60 is attached to the upper surface 51 of the mower deck 50 near its central opening 57. On the upper surface 51 of the mower deck 50, a power device, such as a gasoline engine or a hydraulic motor, may be mounted to power the actuator 60. However, as previously described, the actuator 60 is preferably powered by a take-off box power 44 of the tractor 43. Fig. 4 is a section of the drive of the cutting blade 60 of the trailed mower 42. The drive 60 includes a bevel gear 61 for engagement with the drive gear (not

Ge" is shown), located at the end of the drive shaft of the power take-off box 44, which rotates. The bevel gear 61, in turn, transmits the torque from the drive shaft of the power take-off box 44, which

Me, rotates on the drive shaft 62, installed with the possibility of rotation in the central opening 57 of the deck 2) of the mower 50. The drive shaft 62 rotates at a speed determined by the number of revolutions per minute of rotation 5r of the drive shaft of the power take-off box 44 (or hydraulic motor) and the transmission by the number of the driving gear to the bevel gear 61 (or by the gear ratio of the hydraulic pump to the hydraulic motor).

Ge) The housing of the drive of the cutting blades 63 with the help of small bolts 64 is attached to the I-beam of stiffness 65 fixed on the upper surface 51 of the deck of the mower 50. The housing of the drive of the cutting blades 63 is equipped with a lower ball bearing 66 and an upper ball bearing 67, located inside two Central holes 57, which provide free rotation of the drive shaft 62. The upper end 68 of the drive shaft 62 has an external thread to screw the hex nut 69, which secures the bevel gear 61.

F) The lower end 86 of the drive shaft 62 also has an external thread for screwing the hex nut 71 to which the trimming and processing device 90 is attached, as will be described later. The cutting blade drive 60, as previously described, is a conventional drive of a trailed mower and may be replaced by any other conventional drive adapted to transmit torque to the rotating drive shaft 62 to actuate the trimming and processing attachment 90.

Most importantly, the hole 72 formed in the base 73 of the blade drive housing 63 is sectioned and threaded for the screwing of a fluid tight fitting 74. The fitting 74 is adapted for fluid communication with the fluid container 130, as will be described below. A round flange 75 is attached to the upper side of the base 73 of the housing 63 with 65 bolts 64. The flange 75 includes a middle wall 76, in which a pocket 77 is made around the entire circle. A well 78 is drilled in the upper surface of the flange 75 opposite the hole 72 in the housing.

63. The bore 78 ends in a radial channel 79 made in the flange 75. The channel 79 is closed at one end by a screw without a head, which is hermetically screwed, and continues inside the flange to the pocket 77.

The first radial channel 81 is made in the drive shaft 62 next to the pocket 77 of the flange 75. Round upper and lower gaskets 82, such as Redega! Mods! Ragi Mo. 62-85-8, form a hermetic seal between the pocket 77 and the outer surface of the drive shaft 62, so that the channel 79 of the flange 75 is in through fluid connection with the channel 81 of the drive shaft 62. The channel 81 passes inside and ends in the longitudinal axial channel 83 , made in the drive shaft 62 and closed with a screw without a head 84, which is hermetically screwed. The second radial channel 85, made in the drive shaft 62, exits from the axial channel 7/0 83 for connection with the trimming and processing device 90, as will be described later. The screw 84 is protected, for example, by means of a countersink, as shown in the figure, from hitting stationary obstacles and is removable, which makes it possible to clean the axial channel 83.

Fig. 6 is a vertical projection and partial section, and Fig. 7 is a top view of the trimming and processing device 90 of the trailed mower 42. The trimming and processing device 90 includes a blade holder 92 and at least one cutting blade assembly 100. Preferably, as shown in the figures, the trimming and processing device 90 includes a pair of radially opposite cutting blade assemblies 100.

The blade holder 92 preferably includes an upper half 91 and a reverse, or mirror, lower half 93 hermetically attached to the upper half. The lower half 93 has a plurality of threaded holes for the plurality of countersunk head bolts attaching the upper half 91 to

Lower half 93. A suitable seal (not shown) can be used to seal the upper half 91 and the lower half 93 together. In the center of the blade holder 92, a central opening 94 is made, through which the drive shaft 62 of the cutting blade drive 60 passes. The blade holder 92 also has a hole 95 through which at least one node of the cutting blade 100 passes, next to the edge of the blade holder far from the center. with

As can best be seen from Fig.5, the lower end 86 of the drive shaft 62, which is included in the central hole 94 of the blade holder 92, has an external screw thread. The central hole 94 of the blade holder 92 preferably has i) an internal thread into which the lower threaded end 86 of the drive shaft 62 is screwed, so that the blade holder is securely attached to the drive of the cutting blade 60. Between the shoulder 88 formed on the shaft and the upper half 91 of the blade holder 92 a round spacer 87 is installed to separate the blade holder from the lower Ge! from surface 52 of mower deck 50. Spacer 87 is made of a hard, rigid metal such as 5160 steel, and the blade holder is made of a softer, more flexible metal for a purpose to be described later. The lock washer and hexagonal lock nut 89 are screwed onto the lower end 86 of the drive shaft 62 for rigid fastening of the spacer 87 and the blade holder 92 to the shoulder strap 88.

In the upper half 91 and lower half 93 of the blade holder 92, a liquid channel 96 (Fig. 5) is made, which passes outward from the central hole 94 in the direction of the hole 95. The first annular pocket 97 is made in the middle part of the central hole 94 adjacent to the second annular channel 85 of the drive shaft 62 so that the chute 96 is in through fluid communication with the annular channel 85 as the shaft rotates the trimming and processing device 90. The chute 96 terminates in a second annular pocket 98 (FIG. 8) made in the middle part of the hole 95, so that the blade holder 92 is in through fluid connection with each of the nodes "Cutting blades 100. with c As shown in Fig. 8, the node of the cutting blade 100 includes a shaft 102 placed with the possibility of rotation in . hole 95 so that the cutting blade assembly can rotate relative to the blade holder 92 if the cutting blade 105 and? hits an immovable obstacle, for example, a stone. A hexagonal lock nut is screwed onto the upper end 101 of the shaft 102, which provides the possibility of removing and replacing the sleeve of the cutting blade 104 installed on the blade holder 92, as will be described later. The lower end 103 of the shaft 102 has an external screw thread for screwing on

Here are the bushings of the cutting blade 104. The bushing of the cutting blade 104 has a thread, preferably a screw thread, for screwing onto the screw thread of the lower end 103 of the shaft 102, so that the bushing of the cutting blade 104

Me. rigidly attached to the shaft of the cutting blade assembly. 2) The lower ball bearing 106 and the upper ball bearing 107 are installed by press fitting into the hole 5r 95 of the blade holder 92, providing the possibility of rotation of the shaft 102 and, therefore, the assembly of the cutting blade 100. The upper ball 108 is welded to the upper half 91 of the blade holder 92, and the lower bobyshka 109 is welded to

Ge) of the lower half 93 of the blade holder 92 for fixing the upper and lower bearings in the hole 95. The cutting blade assembly 100, as previously described, is a conventional cutting blade assembly of a trailed mower and can be replaced with any cutting blade assembly adapted to the installation as a minimum of one cutting blade dv 105 per blade holder 92 for cutting vegetation and treating trimmed plants with a special liquid.

A radial channel 110 is made in the shaft 102 next to the ring pocket 98 of the blade holder 92. Round upper

F) ii lower gaskets 82, such as Redega! Mods! Ragi Mo. 62-85-8, form a hermetic seal between the pocket 98 and the outer surface of the shaft 102, so that the radial channel 110 of the shaft is in through fluid connection with the groove 96 of the blade holder 92. The radial channel 110 passes inward and ends in the longitudinal bo axial a channel 111 made in the shaft 102 and closed by a hermetic plug 112, which is welded to the lower surface of the sleeve of the cutting blade 104. The plug 112 has a step that creates a liquid reservoir between the half of the lower surface of the lower end 103 of the shaft 102 and the half of the upper surface of the plug.

The channel 113 is made in the sleeve of the cutting blade 104 and is hermetically closed by a screw without a head 114 on the side opposite to the cutting blade 105. The channel 113 passes outward from the liquid tank in the direction of 65 of the cutting blade 105 and ends at a small gap 115 between the sleeve of the cutting blade 104 and the lower surface 116 of the cutting blade. The gap 115 preferably has a width in the range of 0.6-2.5 cm, and more preferably approx

1.2 cm. It was found that the width of the gap 115 is important for the operation of the "wetted Burch blade" system. If the gap 115 is very wide (ie, wider than 2.5 cm), then there is insufficient capillary attraction of the processing liquid to the lower surface 116 of the cutting blade 105 to maintain a continuous flow of the processing liquid. If the gap 115 is very narrow (i.e., narrower than 0O,bsm), then the drops of processing fluid exiting the channel 113 are not thinned, and capillary attraction may not be sufficient to maintain a continuous flow of the processing fluid on the lower surface 116 of the cutting blade 105. Therefore the processing liquid can spill out and contaminate the surrounding soil and underground water system. The channel 113 can also be provided with a screw thread to give a small swirl to the stream of processing liquid, which 7/0 exits the channel. It is believed that the swirling of the jet improves the capillary attraction of the continuous flow of processing fluid to the lower surface of the cutting blade by preventing the radial spread of droplets in the gap 115.

Fig. 10 is a vertical projection and a partial section, and Fig. 11 is a top view of an alternative embodiment of the trimming and processing device 90 of the trailed mower 42. The trimming and 7/5 processing device 90 includes a disk blade holder 122 and four orthogonally located cutting blade assemblies 100. The disk blade holder 122 preferably includes an upper half 121 attached to a lower half 123, as previously described and shown in partial section of Fig.10. However, above the upper surface of the disc holder blade 122 can be located a second radial channel made in the drive shaft 62 to connect with the pipeline 124, located between the second radial channel and the 2o axial channel 111 of the shaft 102, described earlier in the manner as shown in Fig.12. When the conduit 124, or any other fluid conduit is placed above the disc blade holder 122 and under the mower deck 50, a circular shield 125 is preferably suspended vertically downward from the bottom surface 52 of the mower deck to prevent impact and damage to the conduit 124 by large objects such as rocks.

Fig. 13 is a three-dimensional image of the container for liquid 130 of the trailed mower 42. The container for storing liquid 130 includes at least one liquid tank 132, called here RI O-TNKOI SE I tm Burcha, made of material resistant to ultraviolet radiation, such such as polyurethane, polyethylene or polyvinyl chloride (PVC) plastic. Preferably, as shown in the figure, the fluid container 130 includes a plurality of reservoirs. tm 132, which are removably stacked and supported on the upper surface 51 of the mower deck 50 between the racks 59. The horizontal movement of the tanks 132 is limited by the racks 59, and the vertical movement of the tanks 132 can be limited by a belt (not shown).

The REGO-TNKIO SEiIII!tm 132 reservoir can be filled with processing fluid at another location and then delivered to the work site to prevent the possibility of fluid spillage and contamination of the environment at the point of use. Reservoirs 132 may also be vacuum-filled and hermetically sealed to preserve fluid properties. Thus, the reservoirs of RGO-TNKA SE HER tm represent an environmentally safe and effective means of providing the mower 42 with processing liquid. It should be noted that the fluid reservoir 130 may contain one or more Burch E'O-TNKI reservoirs filled with processing fluid and a separate fluid tank containing an inert solution (eg, water) for mixing with the processing fluid. Preferably, the treatment fluid and the inert solution are mixed, for example, in an injection mixing chamber at the workplace during use. Thus, the concentration of the mixture can change, and in this case it is possible to keep in the warehouse and transport to the workplace a smaller number of tons of tanks of EGO-TNKO SE and tm, "» Fig. 14 is a three-dimensional image, Fig. 15 is a side view , and Fig. 1b6 - a view from the end of the tank "EGO-TNK SE with 132 containers for liquid 130 of the trailed mower 42. Each tank 132 includes an upper wall 133, side walls 134, front end wall 135, rear end wall 136 and lower wall 137 Each reservoir 132 has an inlet 138 and an outlet 139. As shown in B-B of Fig. 41, each inlet 138 includes an enclosing portion 140 of a double shut-off fitting 141, such as a Ragkeg ROI U-TITE F Ricip

F Rai Mo. 398RO manufactured by Ragkeg Nappiip Sogrogayop, Otsego, Michigan, corresponding to the part 142 covered by the fitting. The part 142 of the fitting that is covered includes a spring-loaded clamp lever, so that the fitting 141 is easily disconnected to replace the empty tank 132. The first section of flexible 20 pipe extends outwardly from the lowermost tank 132 and is connected with the second segment of the flexible pipe with the help of the Ragkeg ROI M-TITEF transition fitting through the wall of the housing of the pumping device 150. The second segment of the flexible pipe passes through the pumping device 150 and ends at the fitting installed on the housing 63 of the drive of the cutting blade 60.

As shown in Fig. 16, the flow filter and the cap of the ventilation valve 145 ensure the inflow of ambient air into the tank 132 so that it does not undergo partial rarefaction, which prevents

HF) of the flow of the processing liquid when it is pumped out of the tank by a pumping device. In addition, each EGO-TNKI SE I tm tank 132 has a handle 142 located on the front end wall 135 and rear end wall 136 to facilitate carrying the filled tanks. As shown in Fig. 13 and 15, the lower wall 137 of the tank 132 includes a guide 152 and soles 154. The guide 152 slides along the groove 153 of the upper wall 60 133 of the lower tank 132 and thus practically eliminates the side of the stacked tanks

EGO-TNKI SE | tm 132. In addition, the soles 154 fit into the recesses 124 on the upper surface 133, which minimizes the relative movement of adjacent tanks 132.

If a small area is to be treated, and therefore a relatively small amount of treatment liquid is needed to apply to the trimmed plants, you can use a separate RGO-TNKO SE tm 132 tank. A separate b5 tank 132 can also be used if a certain amount needs to be used on a given area of reservoirs of RGO-TNKI SEI | m containing the same liquid, or if it is necessary to use different processing liquids on the same area. For example, the first tank of RI O-TNKO SE | m, filled with liquid herbicide against dew, can be used for simultaneous application of herbicide against dew on the stems of plants that remain at the time of vegetation cutting. After that, the tank RGO-TNKO SEII tpm containing the herbicide can be removed and replaced with a second tank R O-TNKO SE tm containing a disinfectant solution for washing the pipeline system 190. Then the tank RGO-TNKO SEII tm containing a disinfectant solution, can be removed and replaced with a third tank of R O-TNKY SE tm containing liquid fungicide. The height of the cutting blade above the ground is reduced so that the remaining stems can be cut again, and the fungicide is applied to the plants that are cut again.

However, it is preferable to use at least two RGO-TNKO SEI|Y tm 132 tanks, so that the level of the processing liquid does not fall below the level of the outlet hole 139 of the lowest tank, regardless of the orientation of the cutting blades of the mower relative to the RGO-TNKO SE tank! tm 132. The use of multiple tanks of RGO-TNKIi SEI I tm 132 makes it possible to treat at one time such an area that would be too large for safe treatment using one tank. In addition, the use of multiple tanks

EGO-TNKI SE I tm 132 enables the processing of a large area at once without the need to repeatedly interrupt the cutting and processing operation to fill one large liquid tank. Instead, you can easily remove the upper tanks of EGO-TNKA SE I tm 132 and replace them with new, pre-filled ones.

The pump device 150 (Fig. 4) pumps the processing liquid from the container for the liquid 130 into the drive of the cutting blades 60, so that the flow of the processing liquid continuously enters the evaporation system of the stems of the trimmed plants that remained at the time of their cutting. The pumping device 150 includes any type of variable power pump for pumping widely varying amounts of treatment fluid depending on the speed of the mower relative to the ground surface, as will be described below. However, it is more preferable that the pumping device 150 is a pure peristaltic pump, for example, manufactured by TAT Epdipeegipdoi Vgapioga, Soppesiysi, which pumps the processing liquid through the pipeline system 190 with the help of compression waves at a pressure of about 0.7n/cm?, which (8) produced mechanically using a system of rollers that compresses a flexible tube containing the processing fluid.

Fig. 17 is a three-dimensional representation of the main components of the flow control means 160, and Fig. 20 is a block diagram showing the connections of the main components in the flow control means. The flow control means 160 includes a control assembly 162 that is preferably powered by a power source located on the tractor 43, such as a 12 volt battery 161. The control assembly 162 is electrically connected to a ground speed sensing device 164, preferably located on the rear axle 163 of the tractor 43 at each wheel 165. As shown in View B Fig. 42 and Fig. 18, the device re)

35 of the definition 164 includes a cup-shaped flange carrier 166, which has a perforated structure due to holes 167 "so for the entry of the protrusions of the bridge 163. The flange carrier 166 is located above the outer end of the bridge 163 and passes inward in such a way that the radially outwardly protruding flange 168 of the flange carrier 166 adjoins to an adjustable sensing device 170 attached to the bridge 163. The sensing device 170 is usually placed inside a removable housing (not shown) that protects the sensing element 171 from solid particles that may strike the bridge 163. 2 s The flange 168 is preferably made of ferrous metal and includes a given set of radial teeth 172, placed separately from each other along the perimeter of the flange. The sensing element 171 may be any electronic sensing element (eg, inductive, magnetic, or optical) that produces an electrical signal proportional to the angular velocity of the flange carrier 166 and, therefore, the velocity of the wheel 165 of the tractor 43.

A sensitive element can also be used, which is able to function in a viscous liquid environment, for example, in oil; in this case, the sensitive element is installed in the gearbox of the rear axle or in the cable of the speedometer attached to the rear axle of the tractor. Preferably, a ground speed determination device 164 is attached to each wheel 165 of the tractor 43 m), and the electrical signal from each determination device is fed to the control unit 162. The electrical signal corresponding to the most

For a large speed value, either the signals from both speed detection devices 164 are added and averaged together, or the signals from both speed detection devices 164 are added, averaged, and

Ge) the average value is multiplied by the correction factor, and thus the most accurate value of the speed of the trailed mower 42 relative to the ground is determined.

Fig. 19 is a front view of the adjustment unit 162 manufactured by EZZSO, Ips., Greensboro, North

California, flow control means 160. The control assembly 162 includes a power switch 173 for supplying power to the control assembly 162 from the 12-volt battery 161 of the tractor 43. The switch 173 (F. is preferably a combination of a 24V DC converter 128 and a 24V DC stabilizer The control unit 162 also includes a programmable operator interface, such as a Miivzyrizpi MTA-10 processor 174, for processing preliminary data provided by the operator, such as the width of the section of the cut performed by the trimming and processing device 90 and the volume of the processing fluid , required for application to the treated area, as well as electrical signals from speed detection devices 164.

The processor 174 preferably includes an information screen and a keyboard 175 for scrolling through the command line displayed on the screen and for editing preliminary data used by the processor 174 to determine the speed of the mower 42 relative to the ground. 65 The control unit 162 also contains a toggle switch 176 for turning on the pumping device 150,

There is a bypass toggle switch 177 for bypassing the pumping device, for example, if it is necessary to move the tractor 43 without supplying liquid to the vegetation. In addition, the control assembly 162 includes a green light emitting diode (LED) 178, which indicates that the pumping device 150 is turned on and operating (for example, while the tractor 43 is in motion, or when the bypass device is engaged to flush the processing fluid from the piping system 190), and red DL 179, indicating that the pumping device 150 is turned on, but not working (for example, when the tractor 43 is not moving).

The control unit is also preferably electrically connected to the DC stepper motor 180, which drives the peristaltic pump of the pumping device 150. The processor 174 transmits to the stepper motor 180 an electrical signal proportional to the measured speed of the mower 42 relative to the ground, and the stepper motor 7/0 180 actuates a high-gain peristaltic pump so that a controlled amount of treatment fluid is applied to the vegetation by the trimming and treating attachment 90. The stepper motor 180 is preferably a 250-step linear motor, for example, manufactured by Ipeijidepi Moiope Zuzietv Ips., Brandford,

Connecticut. The output shaft of the stepper motor 180 is attached to the first pulley 181, which drives the second pulley 182 attached to the output shaft of the peristaltic pump of the pumping device 150.

The gear ratio of the first pulley 181 to the second pulley 182 can be any, but preferably 1.0/1.5, so that the maximum speed of the peristaltic pump is not reached.

The control node 162 may also include a global positioning satellite (GPS) transceiver 184 for communication with a remote base via satellite. The receiver-transmitter 184 receives and transmits data regarding the location of the tractor 43 and the mower 42 as the vegetation is processed by the processing Vidyna. In this way, a permanent record of the coordinates of the cultivated area can be made, which is used, for example, when considering the claims of farmers and landowners adjacent to exclusion strips or highways about the contamination of their land with toxic substances.

In an alternative embodiment, the ground speed sensing device 164 may be mechanically connected to the pumping device 150. For example, the flange carrier 166 may include a sprocket instead of the flange 168, and the sensing element 171 may engage mechanically with the radial teeth 172 of the sprocket. to actuate the peristaltic pump of the pumping device 150. The pumping device 150 may be i) actuated directly by the sensing element 171 or may be actuated by a gearbox of any type that converts the output power of the sensing element so that the maximum speed is not reached peristaltic pump. Piping system 190 provides a through fluid passage between the fluid reservoir 130 and the trimming and processing device 90. The piping system 190 supplies the processing liquid to the lower surface of the cutting blade so that the flow of processing liquid continuously flows to the plants at the time of their cutting. with

The pipeline system 190 preferably includes a flexible pipe 191, made, for example, of soft polyvinyl chloride (PVC), which passes from the lowermost tank of the RGO-TNKI CE I tm 132 through the rollers (iso) of the peristaltic pump of the pumping device 150 to the sealed fitting 74, which is outside the housing 63 of the drive "o cutting blades 60. The pipeline system 190 also includes a well 78; radial channel 79 and annular pocket 77 made in flange 75; radial channel 81, axial channel 83 and radial channel 85, made in the drive shaft 62; the first annular pocket 97, the liquid chute 96 and the second annular pocket 98, made in the blade holder 92; radial channel 110 and axial channel 111 made in the shaft 102 of the cutting blade assembly 100; radial channel 113 made in the sleeve of the cutting blade 104. The pipeline system 190 ends with a gap in c 115 on the lower surface 116 of the cutting blade. It is believed that the continuous flow of processing liquid at the time of cutting vegetation is "" of crucial importance for the efficiency of processing. The combination of capillary attraction in the lower part of the cutting blade and the swirling of the processing liquid ensures that the processing liquid will always enter the evaporative system of the plant stems that remain at the time of their cutting, regardless of the speed of rotation of the cutting

Gee! blades, the speed of the mower relative to the ground or the orientation of the cutting blade relative to the tank EGO-TNKIiI SE | mm,

Thus, all the processing liquid is absorbed into the evaporative system of the plants when they come under the cutting

F blade. o Fig. 21 is a diagram of the main components of the electric lawn mower shown in Fig. 1. The electric lawnmower 41 preferably includes a fluid container 230, a flow control means 260, and a pumping device 250, conceptually the same as the previously described liquid container 130, flow control means (Ce) 160, and a pumping device 150, respectively. The main difference is that the components of the electric lawn mower 41 are scaled to match the size and power of the mower. In addition, a filter 200, such as a through-line gasoline filter, may be incorporated upstream of the pumping device 250 to filter solids from the processing fluid prior to its introduction into the cutting blade drive 210. The cutting blade drive 210 is conceptually the same as the previously described cutting blade drive 60 , but also includes collector 220, called here MET VAKgtm (moistened beam) Burcha. име) A typical blade 211 for an electric lawnmower is made of soft metal, has a relatively small thickness and is from 110 to 200 cm in length. Thus, as shown by the dashed line in Fig.21, the blade 211 can 60 bend relative to the drive of the cutting blade 210, so that the tip 212 of the blade 211 can deflect upward when the blade hits a stationary obstacle. Accordingly, if the blade 211 is equipped with a solid fluid pipeline protruding outward from the drive shaft of the cutting blade 210, then the pipeline may deform when the blade bends. MET VAKLM Burcha allows the use of the system of "wetted Burcha blade" on electric lawn mowers with flexible cutting blades. 65 Fig. 22 is a three-dimensional image of the MET VAK tm 220 Burch attached to the drive of the cutting blade 210 of the electric lawn mower 41, and Fig. 24 is a top view of the central part of the UUET VAK tm

Burcha, shown in Fig.22. MET VAK m 220 includes a liquid pipeline 221, which is in liquid connection with a container for liquid 230 in the previously described manner. Accordingly, a continuous flow of treatment fluid is supplied to the lower surface of the blade 221 and continuously applied to the vegetation at

Her cutting. Fig. 23 is a three-dimensional image of an alternative version of the MUET VAK tm 220.

In this variant, the solid liquid pipeline 221 is placed in the longitudinal channel 222, made in the upper plane of the MMET VAESm 220, and welded to the MMET VAKltm 220 in the usual way. In another preferred embodiment, instead of a thin blade 211, a thicker UUET VAKtm 220 can be used for appropriate applications.

Fig. 25 and 26 are sections of alternative versions of the drive part of the cutting blade 360 and the part of the trimming and processing device 350 of the mower according to the invention. The processing fluid passes through the cap 310, which covers one end of the drive shaft 320 of the drive of the cutting blade 360. The cap 310 can be any stationary cap that allows the transmission of the processing fluid into the axial channel made in the drive shaft 320, which rotates. However, it is preferable that the cap 310 is a two-section 75 Hex or ball joint. In the variant presented in Fig.25, the processing liquid is transferred to the blade holder 340 in the previously described manner in accordance with Fig.10. In the variant presented in Fig.26, the processing liquid is transferred to the blade holder 340 in the previously described manner in accordance with Fig.10.

Fig. 27 is a three-dimensional image of a hydraulic roller-packing machine according to the invention, attached to the front outrigger of the tractor. Roll-packing machines are used in forestry and on exclusion zones. The baling machine 400 according to Fig. 27 is a large set of equipment that has sufficient power for felling trees.

Fig. 28 is a three-dimensional image of the high-speed nozzle-saw according to the invention, adapted for use on the hydraulic roll-packing machine of Fig. 27. Equipped with a high-speed saw head 402, the roller bagging machine of Fig. 28 operates like a chain saw, but in this application fluid is delivered to the lower part of the cutting blade, or saw head, prior to (5) cutting to facilitate fluid flow. directly into the vascular system of the treated plant or tree.

Fig. 29 is a three-dimensional image of a high-speed secateur attachment according to the invention, adapted for use on a hydraulic roll-packing machine according to Fig. 27. Equipped with a high-speed secateur nozzle 404, the roller bagging machine of Fig. 29 delivers the processing liquid to the lower part of the cutting blade, or secateur nozzle, before cutting, promoting the flow of liquid directly into the vascular system of the plant or tree being processed. (ze)

Fig. 30 is a partial section of a part of the liquid pipeline of the device for cutting and processing vegetation according to the invention, shown in Fig. 31-38. Cutting mechanisms other than those of rotary mowers, such as drum, chain plate, disc and blade cutters, require "(o) regulated supply of fluid to the respective cutting edges at the appropriate time.

Drum mower 480 (FIG. 35) using a sealed fluid supply device with a hollow shaft 406 described above to supply fluid to the lower cutting edges 482 of the rotating blades 484. This device utilizes a central shaft 486 having a 7/5 fluid delivery device design 406. Attached to the bridge 486 are spokes 488, supporting blades, and a tube 426 that provides fluid flow from the bridge to the blade. Interactions between the rotating blades 484 and the stationary blade or anvil 490 affect both the cutting of the vegetation and the delivery of the treatment liquid directly into the vascular system of the plants. The roller 494 provides movement over the ground 496 and freshly cut vegetation 498. In this system, the pulses of the processing fluid are synchronized so that the fluid is ejected just before the blade contacts the vegetation. Like a rotary mower, this device can be connected to a ground speed controller that controls the amount of fluid passing through the system in a given time.
