Description

  The present invention relates to a sprayer for a chemical solution used for crop control work, liquid fertilizer application work, and the like, and more particularly to a sprayer suitable for use in agricultural house spraying.

  Conventionally, in the control of agricultural crops in small or medium-sized farmland, for example, a chemical tank is held by an operator, the spray bottle is held, and the chemical liquid is sprayed from a plurality of nozzles attached to the spray bottle. A method, a method in which a chemical solution tank and a pressure pump are mounted on a wheeled machine body, and a chemical solution is sprayed from a long pipe having an injection hole are generally known. In these operations, reduction of the labor of the operator who performs the spraying operation, movement within the narrow ridge width, simplicity of operation, low cost, and the like are factors in selecting the sprayer. By the way, when spraying chemicals for crops cultivated in an agricultural house, in the case of the above-mentioned tank-back sprayer, for example, spraying in a house having a short side length of about 6 meters and a long side length of about 100 meters. In manual compression, however, it is actually difficult to work on such a large area. In addition, it is conceivable to install a chemical tank and pressure pump outside the house and spray while supplying the chemical with a hose. In this case, the operator grasps one end of the spray canister in a cantilevered manner and extends the other end. Spray from the nozzle on the side. Then, since the spraying operation is performed for each crop cultivation section when the reed is reciprocated, the chemical sprayed on the forward section side that has already been sprayed drifts to the return path section, for example, when spraying on the return path of 100 meters. As a result, there is a risk that the work will be performed while sucking a large amount of pesticide, and the human body will be adversely affected. In addition, it was hard work because it was forced to work for a long time with the cantilever supported by the spray bottle. Moreover, the chemical | medical solution spray vehicle of patent document 1 is disclosed as an example of what sprays a chemical | medical solution from the long tube which mounts a chemical | medical solution tank and a pressure pump on the body with a wheel, and has a nozzle hole.

JP 2002-34423 A

The chemical spray vehicle disclosed in Patent Document 1 eliminates the labor for the operator to grip the spray bottle and facilitates the management of the chemical. However, depending on the engine or motor drive source, pump, chemical tank, airframe, etc. , advancing the entire device weight is increased device, not only the operator to move the rear Susumu labor intensive, the entire body becomes large, the front and rear small narrow house entrances out or narrow ridge width of the ridge There is a problem that advancement is difficult. Also, when moving the aircraft with an actual kite, it is necessary to make a subtle trajectory correction and change of direction. However, the chemical spray vehicle disclosed in Patent Document 1 is too heavy and the operator can easily correct the trajectory and change the direction. At first glance, it seems to be easy, but in fact it doesn't work well. Furthermore, there was a problem that the cost was high.

  The present invention has been made in view of the above-described conventional problems, and its purpose is to be simple and lightweight and small, and to easily perform subtle corrections, changes, and turning operations without requiring labor. It is another object of the present invention to provide a sprayer capable of reducing the influence on the human body by reducing the suction of chemicals and the like during the spraying operation.

In order to solve the above-mentioned problems, the present invention provides a single rolling part 2, a main body frame 4 mounted on the rolling part 2 via a rolling shaft 16, and a main body frame having one end fixed to the main body frame 4. And a spray rod 6 with a nozzle 5 that opens and closes on both sides of the column 3 in the center, and is connected to a chemical solution supply hose 34 supplied from a chemical solution supply device. A spray tub 6 with a nozzle for spraying a chemical solution from a nozzle 5 and a spray tub 6 stored and closed so that the entire body can be handled and moved in a standing position while the entire body is supported by one rolling part 2. And a straight body structure 7 of the entire body formed in a state parallel to the support column 3, and via an operator 32 that moves in the longitudinal direction of the support column 3 along a guide 28 provided in the longitudinal direction of the support column 3. spray rod 6 from the spray machine 1 provided with an opening and closing operation mechanism 8 for opening and closing operation Te It is made. When the sprayer is simply moved, it is moved in a state where the sprayer is stored and closed and the entire body is made into a straight body. Therefore, a narrow doorway can be easily accessed without breaking the vinyl covering of the agricultural house. Nevertheless, since the spray jars that open and close on both sides of the support are provided, the aircraft is moved to the end of the agricultural house, and the spray jars are opened only when moving the vine in the return path and sprayed on the cultivation plots on both sides simultaneously. Let Therefore, the operator does not directly suck agricultural chemicals and the like, and the influence on the human body can be reduced. Since there is no chemical tank, prime mover, or pump installed, and it moves in a standing position at one rolling part, the load on the operator when moving the machine is extremely small, and the direction, correction, and turning of the machine are easy. It can be done freely. Furthermore, it is easy to move to another building. The main body frame and the support can be made of metal or light metal, but can be made of synthetic resin plastic, FRP material, etc. to reduce the weight. Further, when the opening / closing operation mechanism 8 for opening / closing the spray tub 6 is provided via the operation element 32 that moves in the longitudinal direction of the support column 3 along the guide 28 provided in the longitudinal direction of the support column 3, the machine body is moved in a standing position. When opening the spray mist and performing the spraying operation, it is possible to easily open the spray tub with a reasonable posture. The opening / closing drive mechanism of the spray tub may be a motor drive or the like, but it is preferable to use a link mechanism or the like for light weight and low cost.

At that time, it is preferable to provide a stand 22 in the vicinity of the rolling portion 2 that protrudes at a required angle with respect to the longitudinal direction of the column 3 and holds the straight body (7) in an upright state. The stand can stand up and fall freely with respect to the main body frame using a hinge or a spring, but may be fixedly attached at a predetermined angle. Although a board | plate material, a filament material, etc. can be used, it is good to form using a filament material for weight reduction.

  The other end of the support column 3 may be provided with a handle 33 that can be manually pulled by gripping the entire machine body while the lower end side is supported by one rolling part 2 and the entire machine body is inclined. The specific handle shape can be arbitrarily configured, such as an annular shape, a block shape, or a T-shaped hook shape. You may provide a finger-shaped recessed part in a grip part.

  Further, the spray basket 6 may be fixed so as to be rotatable around its longitudinal axis. Since the spray radiation angle of the nozzle of the spray rod opened on both sides from the support column is adjusted, the angle at which the chemical spray is most difficult for the worker to adhere to during the work can be freely set.

  Moreover, the rolling part 2 is good to be formed with the unicycle. The rolling part itself may be a rolling wheel in which a plurality of wheels are closely arranged in parallel, but a unicycle is excellent in terms of light weight and a small turn.

According to the sprayer according to the present invention, one rolling part, a main body frame mounted on the rolling part via the rolling shaft, and a support column having one end fixed to the main body frame and integrated with the main body frame And a spray bottle with a nozzle that is openable to open and close on both sides of the column with a center, and is connected to a supply hose for a chemical liquid supplied from a chemical liquid supply device and sprays the chemical liquid from the nozzle, ,
A straight body of the entire aircraft, which is formed in a state where the sprayer is stored and closed and parallel to the support so that the entire aircraft can be handled and moved in a standing position with the entire aircraft supported by one rolling part. The structure is simple, lightweight and compact with a simple structure, and can be easily modified, changed, and rotated in a subtle direction of movement without labor, is low cost, and is sprayed. It is possible to reduce the influence on the human body by reducing the suction of the chemical solution at the time of work.

  In addition, by providing a stand that protrudes in the vicinity of the rolling part at the required angle with the longitudinal direction of the support and holds the straight body in an upright state, especially in a narrow space such as a house entrance and exit when standing up and down It is practical to improve the convenience of handling when it is stopped and then moved again, or when other work is performed while standing on its own.

  In addition, the other end of the support column is provided with a handle that supports the lower end side of one rolling part and holds the entire body tilted so that the entire body can be manually pulled. The operator can hold the upper part of the machine and move the aircraft and control the direction easily. In addition, the operator can stably hold the upper end portion of the support when the aircraft is gripped and pulled by the rear hand during the return spraying operation in the agricultural house.

  In addition, the spray bottle is configured to be fixed so as to be rotatable about its longitudinal axis, so that the spray radiation angle of the nozzle of the spray bottle opened on both sides from the support column is adjusted so that the chemical spray is most applied to the worker during the work. The angle at which it is difficult to adhere can be set freely.

  In addition, the structure is equipped with an opening / closing operation mechanism that opens and closes the spray bottle through an operation element that moves in the longitudinal direction of the support along a guide provided in the longitudinal direction of the support, thereby moving the aircraft in a standing position. When the spray bottle is opened and the spray work is performed, it is possible to easily open the spray bottle with a comfortable posture.

  Further, when the rolling part is formed of a unicycle, the entire body is reduced in weight, the operation of the body and the control of the movement are simple and easy, and the practicality is high due to the small turning.

It is a schematic explanatory drawing which shows the working state using the sprayer of FIG. It is side surface explanatory drawing which served as operation | movement description of the sprayer which concerns on 2nd Embodiment of this invention.

  Next, the sprayer which concerns on 1st Embodiment of this invention is demonstrated with reference to FIGS. The sprayer of the present invention is a sprayer used for a chemical solution for controlling crops, fertilization of liquid fertilizer, and the like, and is used by being connected to a supply hose that supplies a chemical solution from a chemical solution supply device.

  1 and 2, the sprayer 1 of the present embodiment is provided with one rolling part 2, a support column 3, a main body frame 4 mounted on the rolling part 2, and a retractable storage on both sides of the support column. The nozzle 5 with the nozzle 5 and the straight body structure 7 of the entire machine body are provided. That is, the sprayer 1 according to the embodiment does not include a chemical tank, a pump, or a prime mover, and includes only the support column 3, the main body frame 4, and the spray basket 6 except for the rolling unit 2. For this reason, the overall weight is light, and the standing position is vertically long, and is extremely small in plan view as compared with, for example, the device disclosed in Patent Document 1. Here, the straight body structure 7 means that the spray frame 6 is retracted and closed so that the entire body can be handled and moved in a standing position while the entire body is supported by one rolling part 2. It is the structure of the whole airframe formed in a state parallel to. As will be described later, even if the support column is bent and used, if the main part of the support column is formed in a state parallel to the support column 3 when the spraying tub 6 is stored and closed, the columnar structure 7 is used. is there.

  The rolling unit 2 is rolling means that is the only ground moving travel unit during the movement of the machine body. At that time, as shown in FIG. In the embodiment, the rolling part 2 is formed by a rolling wheel 14 as a unicycle in which a tire 12 is mounted on a hub 10. The rolling unit 2 is not necessarily limited to a unicycle, and two or more rolling wheels may be closely and coaxially connected. However, when a unicycle is used, it has a small turn and has a delicate traveling direction. Not only can corrections, changes, and turning be performed easily, it is also lightweight and easy to handle the entire aircraft. Further, the rolling part may not be a wheel with a tire but only a wheel.

  The main body frame 4 is a base on which the support 3, the spray basket 6, and the like are mounted on the rolling part 2 while allowing the rolling part 2 to roll on the grounding side. In the embodiment, the rolling shaft of the rolling wheel 14 is mounted. 16 is laid on the rolling part 2 via 16. Specifically, as shown in FIGS. 1 and 3, rolling shafts 16 are attached by penetrating the shaft holes of the hub bearings and projecting from both ends of the hub 10, and the body frame 4 is mounted on the rolling wheels 14. The reverse U-shaped board part 18 provided so that a half part may be straddled non-contactingly, and the flat part 20 fixed to the upper surface of the reverse U-shaped board part 18 horizontally are included. The main body frame 4 is made of, for example, iron or stainless steel, other metal, synthetic resin plastic, or the like.

  As shown in FIGS. 1 and 3, the main body frame 4 may be formed of a plate material having a width sufficiently narrower than the tire diameter in an inverted U shape, and can be configured in a small size. In the embodiment, a standing stand 22 is attached to the main body frame 4. The standing stand 22 is a standing posture support means that is used when the sprayer 6 is closed and the sprayer is set up to stand up in a straight body and temporarily placed, and the like in the embodiment. The opposite U-shaped side walls 4 a and 4 b of the main body frame 4 extend in the radial direction and pivotally support the rolling shaft 16 at the center position, and are perpendicular to the radial direction, that is, in the longitudinal direction of the column 3. On the other hand, a stand 22 for standing is projected and attached at right angles. The projecting direction of the standing stand does not have to be perpendicular to the longitudinal direction of the support column 3 and may be attached at an arbitrary angle that can support the standing position together with the rolling wheels in the inclined state. In the embodiment, the standing stand 22 is formed of a metal wire that forms a loop of a deformed square frame to reduce the weight. As shown in FIG. 2, the stand 22 for standing is supported by grounding the protruding end side of the stand and inclining the aircraft to the protruding end side of the stand as shown in FIG. At this time, the load is shared and supported by the protruding end of the stand and the rolling wheel 14. Temporary fixing members 24a and 24b for temporarily attaching and detaching the middle part of the chemical solution supply hose are attached to the inverted U-shaped plate portion 18 and the standing stand 22 of the main body frame 4 to supply the chemical solution. The side close to the end of the chemical supply hose that is connected to the device 60 and supplies the chemical to a place separated from the device is temporarily fixed to facilitate the collection. Incidentally, hook-shaped temporary fixing members 24 a and 24 b are fixed to the inverted U-shaped plate portion 18 of the main body frame 4, and ring-shaped temporary fixing members 24 a and 24 b are fixed to the distal end side of the standing stand 22.

  The support column 3 extends in one direction from the rolling wheel and is installed at the center of the machine body to store and support the spray basket, and to form a main body framework that controls the movement of the entire machine body and the holding of the standing position by its gripping and manual operation. It is composed of a shaft that is long in the direction. In the embodiment, the column 3 is fixed to the flat portion 20 of the main body frame 4 with a screw by using, for example, a triangular angle member with a longitudinal direction set in a direction perpendicular to the flat surface. As shown in FIG. 8, the support column 3 is formed of, for example, a square bar-shaped aluminum mold material, and a guide 28 including a long groove 26 is formed in the longitudinal direction thereof. The guide 28 is not limited to the configuration of the long groove, but may be configured of a rolling element that is mounted on the rail and moves. In the embodiment, a rod 30 as a sliding member is slidably disposed in the long groove 26 of the guide 28, and an operation element 32 such as a knob is attached to the upper end of the rod 30 toward the operator's operation side. It has been. The guide 28 and the rod 30 constitute an opening / closing operation mechanism 8 for operating the opening / closing movement of the spray basket. The opening / closing operation mechanism 8 opens and closes the spray basket 6 in conjunction with the opening / closing drive mechanism 9. Further, a handle 33 is attached to the upper end side of the support column 3 for the operator to hold. The handle 33 is a gripping part that moves the entire machine body while supporting the load by supporting the load by supporting the load by supporting the load by supporting the load by supporting the lower end side of one rolling part 22 and tilting the entire machine body. In particular, in the sprayer 1 of the present invention, when the operator performs the spraying operation while pulling the sprayer 1, the spraying chemical liquid is hardly sucked directly, and the working environment can be greatly improved.

The spray bottle 6 is an injection unit that attaches a plurality of injection nozzles 5 to the longitudinally separated positions and injects the chemical liquid around. In the embodiment, the lower end base is connected to the opening / closing drive mechanism 9 and the upper end side (the other end side). ) Are opened and closed so as to be displaced in a fan shape from the state of FIG. 1 to the state of FIGS. The spray tub 6 is a hollow straight tube, and is connected to a connection hose 34A connected to the chemical solution supply hose 34 by a retaining ring (not shown) on the lower end side. As shown in FIG. 9, the injection nozzles 5 are set so that their injection directions are alternately enlarged so as to form a required angle θ with each other. In the embodiment, as shown in FIG. 6 , the base of the spray tub 6 is connected to a first link arm 36 that performs a reciprocal a operation between the vertical direction and a position opened from the position in the outward direction. The first link arm 36 is provided with clamping members 38a and 38b that can be tightened and released. The spray rod 6 is attached to the first link arm 36 so as to be rotatable around its longitudinal axis through an operation lever 40 for operating the clamping and release. (See FIG. 7). Thus, by rotating the spray basket 6 around the longitudinal axis, the radiation direction at the injection angle θ can be adjusted, and when spraying the chemical liquid while pulling the sprayer 1, an angle that is difficult for the operator is set. The spraying operation can be performed by arbitrarily setting.

  The spray bottle 6 is directly opened and closed via an opening and closing drive mechanism 9. In the present embodiment, a substrate 42 is fixed in a horizontal direction perpendicular to the column 3 at a position near the lower end of the column 3. The opening / closing drive mechanism 9 includes a first link arm 36 and a first link arm 36 which are pivotally supported at both ends of the substrate 42 and reciprocally rotate in a fan shape in the vertical direction and the outer 90 ° direction on the upper end side. One end (lower end) is pivotally supported 46 on the upper end side, and the other end (upper end) is pivotally supported 48 on the lower end of the slide rod 30, and the second link arm 50 moves up and down linearly by the vertical movement of the slide rod 30; Are symmetrically provided. The upper ends of both the second link arms 50 and the pivot portion 48 on the lower end side of the slide rod 30 are pivotally supported by a common shaft. Both the second link arms 50 are formed in an inverted V shape when the spray basket 6 is stored and closed, that is, parallel to the support column 3 and the airframe is a straight body. 48 descends from the state shown in FIG. 1 along the guide 28 and is displaced in a straight line in the horizontal direction with the spray tub 6 opened at a maximum angle (for example, about 130 degrees) as shown in FIG. As a result, as shown in FIG. 6, the spray rod 6 can be opened and closed by moving the operating element 32 up and down, and the operator can move his hand lightly up and down in an easy posture while standing. The spray can 6 can be set to open at an arbitrary opening degree. 5 to 8, on the back side opposite to the projecting side of the operating element 32, biasing springs 52 having both ends connected to the upper end sides of both the left and right first link arms are connected to the upper ends of the first link arms. By being urged in the pulling direction, the operator can easily operate it with a light operation when the operator moves the knob of the operating element 32 up and down.

1 and 4 , reference numeral 54 denotes a fixing bracket for the handle 33, and reference numeral 55 denotes a locking member that locks the chemical solution supply hose 34 along the support column. So that it does not get in the way when the operator moves or moves the aircraft. In the present embodiment, the chemical supply hose 34 is provided with a connection hose 34A so as to be freely connected and disconnected, and a connector 35 is attached to the end thereof so that it can be connected to and disconnected from the main body hose 34 in one touch. Yes. Reference numeral 56 denotes a lock lever used when the substrate 42 is moved up and down along the support column 3 and the spray position is adjusted up and down in accordance with the growth height of the plant.

  Next, the operation of the sprayer 1 according to the embodiment will be described. An end portion of a chemical supply hose 34 in which a prime mover, a pump, and a chemical liquid tank are installed outside the agricultural house (see FIG. 11) 100 and one end is connected to the pump. Is connected to the connection hose 34A via an attachment with an opening / closing cock (not shown). The sprayer 1 is placed in a standing position using, for example, a stand 22 and the spray tub 6 is closed to form a straight body. Then, the worker faces the front side FR side, holds the handle 33 with the back side RE facing forward, and enters the agricultural house while lightly pushing the machine body, for example, in an inclined position. Agricultural houses, for example, have recently been stretched with 3 to 4 layers of vinyl covering to form 2 to 3 heat insulation layers, and the doorway is in a form that opens and closes in a double-speech manner. The entrance is extremely narrow and is easy to tear because it is vinyl. The worker M enters the house into the house so as not to break the vinyl, and operates the handle while pushing the body with the sprayer 1 tilted slightly obliquely. While pushing the airframe, proceed to the end of the house, for example, 100 meters ahead with the rear side RE facing forward. For example, a stand 22 is used to stand and stop at the end position, which is the dead end of the house, and in this state, the operating element 32 is turned in a loosening direction to release the lock, and is pulled downward linearly. As a result, the opening / closing drive mechanism 9 composed of a link mechanism is operated, and the spray tub 6 is expanded as shown in FIGS. In this state, when the open / close cock as a hand switch is operated to bring the chemical liquid into the pumping state, the spray is sprayed radially into the house from the nozzle 5 of the spray basket 6 as shown in FIG. At this time, it is sprayed radially on the cultivation sections P on both sides of the straw. In this state, the worker M inclines the aircraft toward the front side FR (in the direction opposite to the direction of the fall in FIG. 2). For example, the operator pulls the aircraft with his back and returns to the return path. Since the rolling part 2 opens the spray basket 6 even in a unicycle and extends the tip of the spray basket with the same length on both sides of the support column 3, the left and right balance is maintained, and it can be moved even if the aircraft is pulled backwards stably. it can. In this way, the chemical spray is performed only when walking along the return path of the corridor in the house. Accordingly, there is no chemical liquid gas such as agricultural chemicals in the direction of travel of the worker, so that the worker can as much as possible have no influence on the body without sucking them. Further, the entire load of the aircraft is extremely light because no power or chemical tank is mounted, and can be configured to be, for example, about 7 kilograms or less. Furthermore, entering and exiting the house is easy, vinyl is not damaged, and further, operations such as changing the course and turning inside the house can be performed very easily.

  FIG. 12 shows a second embodiment of the sprayer according to the present invention. In the sprayer 1-2 of the second embodiment, the front FR side of the prop 3 via a bent portion 70 provided at an intermediate position in the longitudinal direction. The first embodiment is that the upper half strut 3A and the lower half strut 3B are fixed at an arbitrary bending angle provided in a manner that can be freely changed in a manner that is bent in an L-shape and a manner that is linearly extended. Unlike the first embodiment, the other parts have the same configuration as in the first embodiment. The spray machine of 2nd Embodiment also supports the lower end side with the one rolling part 2, and the point which comprises the straight body structure used as a straight body is the same as that of 1st Embodiment. The bent portion 70 is configured such that the upper and lower ends of the lower half column 3B and the upper half column 3A are pivotally supported by a bent shaft 72 in a fitted state. Then, the fastening device 74 tightens these bent portions and is provided so as to be freely releasable so as to hold the upper and lower half struts in a bent state at an arbitrary angle and further return to the extended state. In the embodiment, a nut and bolt lever type fastening device is used as the fastening device 74, but a specific device configuration is arbitrary. In the embodiment, the vertical movement stroke operation of the operation element 32 is performed at a lower position than the bending portion 70. As shown in FIG. 12, the spray basket 6 can be sprayed from the nozzle 5 even in a state of being stored and closed. For example, as in the first embodiment, the target crop to be sprayed by opening the spray basket 6 in both sides in a fan shape is to grow and bear fruit in places close to the ground such as watermelons, melons, and strawberries. However, for example, tomatoes and eggplants that grow and bear fruit in a standing tree state are more efficient in spraying chemicals to crops by spraying in the horizontal direction while moving the straw. In this case, as shown in FIG. 12, the spray basket 6 is retracted and closed and converged in a parallel state with the support column 3 to form a straight body, and in this state, the fastening member 72 is loosened to loosen the upper half support column 3A. Can be fixed to the front side FR at an arbitrary bending angle, and the liquid can be sprayed while pulling the aircraft. Thus, even if the spray tub is pulled in a closed state, the total weight is, for example, about 7 kilograms or less, so that the T-shaped handle can be gripped and operated reliably. In the sprayer of this embodiment, spraying can be performed by using both crops that grow at a low position with respect to the ground, such as watermelons, and growing crops that are standing trees, such as tomatoes and eggplants. In particular, even when spraying with the prop 3 bent to the front FR side in the L shape and the spray tub 6 closed and standing, the handle 33 is gripped and pulled at a position spaced from the spray position. Therefore, even when spraying standing tree crops, the operator can minimize the risk of sucking the chemical solution.

  The sprayer of the present invention is not limited to the configuration of the above-described embodiment, and modifications within the scope not departing from the essence of the invention described in the claims are also included in the present invention.

  Although the sprayer of the present invention is applied to spraying in an agricultural house in the above embodiment, it can also be applied to drug spraying in other alley cultivation. Furthermore, it can be effectively applied not only to agricultural chemicals but also to liquid fertilizers.
