Description

[Detailed description of the invention] [Industrial application field] The present invention enables compressed air to be vigorously ejected into the deep layer of the soil, causing cracks in the cultivated soil by the flow of the jet, thereby expanding and softening the soil, and supplying air into the soil. The present invention relates to a self-propelled tillage soil improvement machine. [Prior art]

The soil improvement machine for this scale is known to be a manual type, such as the one described in Japanese Patent Application Laid-open No. 58-56603 (Funkary Samurai IB improved machine), which was proposed earlier by Mizu Applicant. ■A model in which a ma/e blower device is mounted on a self-propelled vehicle such as a tractor so that it can be raised and lowered is also available, for example, in JP-A-58-12G701.
J and C have been proposed in Japanese Patent Laid-Open No. 1983-216601 (self-propelled vehicle equipped with automatic tiller expansion device), etc. Prior art of the former ■ (JP-A-58-513603 @
(described in the official gazette), the soil conditioner is moved manually,
While the jets are operated manually from a moving position,
The prior art of the latter (JP-A-58-126701,
JP-A-58-21 (described in Publication No. 3601) is easy to move because the blower device, which is the working part, is mounted on a self-propelled vehicle such as a tractor. Nonoko. Although there is an advantage in that the capacity of the air tank can be increased, these prior art techniques have a configuration in which the self-propelled vehicle temporarily stops traveling at the fume position and the fume operation is performed by moving the fume device up and down in the stopped state. As such, self-propelled vehicles must frequently start and stop during work, and although they may be easier to move than manual vehicles, they cannot be expected to significantly improve work efficiency. Therefore, in order to achieve swelling and softening of cultivated soil using air fumes even while driving, the fumarole part is plunged into the soil and towed, and during this process, compressed air is intermittently passed from the fumarole part. A soil expansion and softening machine was developed in 1983, which was designed to expand and soften the soil by causing cracks in the cultivated soil by atomizing it into the soil. This is proposed by Japanese Patent No. 125201.

Technical Problem 1 of the Invention The present invention is a self-propelled tillage soil improvement work machine as seen in the prior art (2) above, and this type of self-propelled tillage soil improvement work machine has the following problems. be. In other words, in this type of self-propelled soil improvement work machine, the fumarole part plunges into the soil and is pulled forward, so a large amount of traction is applied to the support part (fumarole strut) of the fumarole part that covers the soil. This creates resistance. This has traditionally been the biggest problem with J3 subsoil crushing I, which is generally known as a similar type of work machine for morning soil improvement. , which requires a large tractor, etc. I
The overall size of the M was unavoidable. (Objective of the Invention 1) The present invention was proposed to solve the above-mentioned problem, and it promotes a self-propelled soil improvement work machine devised to be able to reduce traction resistance to a large 1]. In order to achieve this purpose, the tillage improvement f1 commercial machine according to the present invention is designed to reduce the size of the towing vehicle. , a jet fuel branch is installed and towed by the vehicle and advances vertically through the LIJI, and this jet fuel support is equipped with a main jet nozzle at the lower end and a nub jet nozzle at a position above it. Both jet nozzles are connected to a compressed air supply source installed above the ground through air supply passages provided along the pillars, and air jets from the respective jet nozzles are connected to the air supply system path. l
This system is characterized in that it is equipped with a valve mechanism that controls the flow rate, and air is ejected from the fume nozzle in multiple stages while the machine is moving underground.

A pair of fume struts 14 are attached to the left and right end portions of the main body frame 6 and hang down in the downward direction LJ. Above this, air fumes 24 as sub fume nozzles are installed in two stages, upper and lower, and each air fume 15.24 is installed substantially horizontally in the tangential direction. In addition, this fumarole branch 14 is slightly inclined so that its lower end is located slightly forward of the upper base when viewed from the side, and there is a blade edge 14 on its front edge.

The other end of the vent hole 17 opened to the middle gas 15 is in communication with the lower end of the air supply @16, and the upper end of the air supply i1G is connected to the fume through the solenoid valve 19. They are installed on both sides of the base of the support column 14 and are communicated with the first sub-tank 20. On the other hand, the air fume 24 as the sub fume nozzle is

The upper end of the air supply passage 16a is connected to the 24th knob tank 20a via the solenoid valve 19a. The solenoid valves 19, 19a, and 19a installed on the main J3 and sub air supply systems are each opened and closed by a switch mechanism in a switch box 191 installed at the rear of the compressor 10. The opening and closing of solenoid valve 1 is due to the action described below.
The poem that released 9 is! 11 The compressed air in the sub-tank 20 flows from the main side blowhole 18 to Bz, Bz・
When the fumes are sequentially emitted into the soil at intervals of..., and when the other solenoid valve 19a is opened, the second sub-tank 2O
The compressed air in a is shown in Fig. 4 from the blowhole 25 on the sub side.
l'B1. [The timing is set so that fumaroles are sequentially emitted into the soil at each of the 32 intermediate positions C. The first and second sub-tanks 20 and 20a are communicated with the main tank 11 via a communication pipe 21,
The solenoid valve 19.19a7a-1til transfers the compressed air stored in the sub tank 20.20a to the blowhole 1.
8.25, immediately after that, compressed air is filled from the main tank 11 into the sub tank 20.20a via the communication pipe 21 and the pressure is accumulated. In addition, a coulter 23 is attached to the front side of the fumarole branch 14 via a support arm 22 extending forward from the main body frame 6.
The fumarole branch 14 cuts the moving soil surface to a predetermined depth. In the above (?4 configuration), the hollow interior of the main body frame 6 may be used as a sub-tank, and the blower struts 14 and air blowers 15 are not limited to the two shown, but may be arranged in multiple lines. Valve 19 is also good.
The opening/closing means may be replaced with other known mechanisms and may be configured to open and close the valve automatically or manually. Next, the FI version of the embodiment described above will be explained. III The improved working machine 5 is attached to the rear of the tractor 1 via a three-point linkage device 4, and is attached to the PTO shaft 1a of the tractor.
from the input shaft 10a of the compressor 10 via the power transmission system 12.
C transmits the rolling force to 1 (11). When traveling, C lowers the fumarole column 14 and the air fume 15 from the ground by 1.1
, the soil is plunged to a predetermined depth and towed by the tractor 1. During this towing, the coulter 23 cuts the field surface to a predetermined depth, and the fume branch 14 advances while cutting the soil from side to side. However, the air jet 15 moves forward 4 degrees horizontally in the deep layer. During this process, the solenoid valves 19 and 19a are opened at a predetermined timing by operating the switch in the switch box 19b, and as a result, the compressed air stored in the first subtank 20 is transferred to the supply air.
The compressed air in the second sub-tank 20a is vigorously ejected from the main-side blowhole 18 through the ventilation hole 17, and the compressed air in the second sub-tank 20a is ejected from the sub-side blowhole 25 through the air supply vent RA1&a. As shown in FIG. 4, this ejection of high-pressure air causes cracks to occur in the soil, causing the soil J1i to swell and soften. At this time, the timing of air supply from the main side fumarole hole 1B is set to the crack generation area D1, which is populated by the fume gas at the fume amount of 1iBt and 8t shown in FIG. D2 is set at intervals such that the jets do not overlap each other in the traveling direction. This is the crack occurrence area D1. This is because if D2 polymerizes, blow-by air will occur from the interlocking portion, making it impossible to expect a sufficient cracking effect. With such a fumarole interval, while moving from the fumarole position B1 in the previous stage to the fumarole position B2 in the next stage, the fumarole branch 14 will pass through the crack light area C1 caused by the fume volume @B1 in the previous stage. It is expected that the traction resistance will be reduced, but the passage of the crack occurrence area 1] 1 is the section from point
In the section 1 up to the point, the fumarole branch 14 passes through the soil 111 where no cracks occur, and the traction resistance increases in this section. In this case, in the present invention, the fumarole from the main side fumarole hole 18 is located at B1. Since the opening/closing timing of the solenoid valve 19a is set so that the jet is emitted from the sub-side jet hole 25 at each intermediate position CI%: J5 of Bz..., the main-side jet jet is at the main-side jet position B1. ．． A crack (crack region E) occurs in the middle part of Bz due to the fumes from the sub-side fumarole hole 25. Due to the occurrence of this crack area E, when the fumarole branch 14 moves from the fumarole position B1 on the main side to 82..., the thin soil on the front side where the branch 14 passes expands and softens, causing the fumarole support 14 passes through the crack generation region E even in the section where it moves from point Y to point 7, and an increase in traction resistance in that section can be avoided. In this way, the fumarole column 14 is constantly expanded and softened in the crack occurrence area while it is moving through the soil, so the traction resistance is greatly reduced, and the soil 111 is not easily removed from the main fumarole hole 18. Cracks caused by fumaroles in Kosumi M area D1. D
In the middle part of z, a crack generation region E is further formed by the fumes from the sub-fumarole hole 25, so that the entire surface of the deep layer 4:1 soil can be swollen and aggregated. In addition, as mentioned above, the sub-fumarole hole 25 is smaller than the main-side fumarole hole 18, and the amount of fumarole is small.
Since the crack generation I+: region E is also small and the fumes are generated at an intermediate position between the fume positions Bx and Bz on the main side, there is no inconvenience that the fume flow on the main side blows through from this part. FIG. 5 shows another embodiment of the present invention. In this embodiment, the air fume 24 as the above-mentioned sub-fumes nozzle is arranged to protrude largely forward χ with respect to the fume branch 14. d) The only difference from the previous embodiment is that the other configurations are the same as those of the previous example. Therefore, corresponding parts will be given the same reference numerals and their explanation will be omitted. In the case of the embodiment shown in FIG. 5, since the sub-side blowhole 25 is arranged far ahead of the main-side blowhole 18, the blow timing of both blowholes 1s:25 is made to be the same. You can get the advantage that you can. In each embodiment, the fumarole holes 18.25 are connected to the fence diameter portions 15c and 24a on the tip side of the air fumarole 15, so that the fumarole holes 18.25 are both on the tip side. 81+, which prevents clogging of the fumarole holes 1B and 25. Also, the outer diameter of the cylindrical part 15a is larger than the outer diameter of the tip part 15b. Therefore, the large-diameter cylindrical part 15a of the soil passage hole 1 at the tip part 151) acts to seal the soil passage hole 15a, thereby allowing n-pressure air to flow backward from the soil passage hole formed behind the cylindrical part 15a. Since there is no blow-through, the high-pressure air is blown into the tightly packed soil and can reliably cause cracks in the fine soil. Note that the air supplied from the left and right blowholes 18.18 may be emitted at the same time, but they should be emitted alternately.
It is also possible to vary the strength and weakness of the fumarole pressure. Note that the high pressure air ejected from the fumarole 18 is
For example, the thickness and shape of the fumarole branch 14 above the air fumarole 15 may be changed as appropriate in order to reduce the loss of blowing to the above ground through the gap between the air fumarole 15 and the soil. . 1. : If the blade edge of the branch is formed in the shape of an arrowhead, the traction resistance of the blower strut 14 will be lower (also from this point of view). [Effects of the Invention] As explained above, the self-propelled jK According to the improved cultivation machine, the compressed air blow nozzles that cause cracks in the tilled soil are made into multiple main and sub blow nozzles, and while the soil is progressing into the soil, the sub blower is installed at an intermediate position between the main blow nozzles that would normally cause blow cracks. Since the side fumarole was created to create the China crack, the fumarole branch always moves through the 11 soil part that has expanded and softened due to the alkaline crack, which greatly reduces the traction resistance of the pillar. As a result, according to the present invention, since the traction resistance is small, the towing vehicle can be downsized, and the towing vehicle can be equipped on a small-sized tractor or the like to accomplish tillage improvement work.
