Description

[Detailed description of the invention] [Industrial application field]. The present invention is capable of blowing compressed air forcefully into the deep layers of the soil, causing cracks in the cultivated soil by this jet stream, thereby expanding and softening the soil, and supplying air into the soil. This relates to a self-propelled tillage soil improvement machine. [Prior art]

As this type of self-propelled soil improving machine, the rear part of the 1-Rakuta is equipped with a jet nozzle that plunges into the soil and can be towed. A soil swelling and softening machine was developed in Japanese Utility Model Application Publication No. 125201/1987, which was designed to cause cracks in cultivated soil by emitting a fume into the soil, thereby swelling and softening the soil.
There are t plans.

[Technical problem of the invention]

The above type of self-propelled soil improvement machine has the following problems. In other words, the fumarole part is injected into the soil via the fumarole branch, so that during the fumarole, the compressed air does not form in the gap between the fumarole branch and the soil or in the path of the fumarole branch. This is a phenomenon in which blow-through occurs upward through the vertical grooves. The phenomenon of such a stairwell is that the pressure of the -C jet stream instantly decreases due to the leakage of air from here, so the effect of cracks in the soil caused by compressed air is 1.
There is a problem in that the intended purpose (swelling and softening of soil due to cracks) is not achieved and 4T is not achieved. In addition, even if the ejected air does not cause a stairwell, the cracking effect will be reduced due to air leakage, and the soil in the specified area will not be able to reliably expand and soften to the depths. In the J, T, -1:, 'yU: type of self-propelled tillage machine, the thread and work equipment are connected to the tractor using a three-point link hitch mechanism. The conventionally well-known three-point link hitch (K
M4715 has a hydraulic lifting device on the lower link! , :1], while working, the work equipment is controlled up and down. This has the disadvantage that the working machine part (air fume) floats upwards.As a result, the position (depth) of the air fume as it plunges into the soil and is being towed is unstable. Therefore, the depth of the soil swelling area due to the fumarole becomes stable.
There were some drawbacks.

[Purpose of the invention]

The present invention was proposed with the aim of solving the above-mentioned problems.The present invention is directed to the vertical direction in which fumarole flows are formed in gaps between a series of fumaroles and the soil or in the tracks of the fumarole branches. It can prevent blowing from the passage groove into the soil, and it can also be installed and towed by a self-propelled vehicle such as a tractor while traveling through the soil.

Therefore, the rear ends of the left and right wing bodies 25 are continuous with the 11+i part of the fume branch 14 and extend so as to protrude rearward from the branch 14. The other end of the vent hole 17 opened to the fumarole 15 is attached to the back of the fumarole strut 14 (communicates with the lower end of the supplied air quality 1G), and the upper end of the air supply pipe 16 The solenoid valves 19 are connected to the stage fuel tank 2 on both sides of the base of the blower strut 14 via solenoid valves 19. This valve 19 is operated to open and close by (not shown).
The opening/closing timing of the i+J function is adjusted as appropriate. In addition, the main tank 11 and the subtank 20 are connected by a communication pipe 21, so that when the solenoid valve 19 is opened and the compressed air stored in the subtank 20 is ejected from the blowhole 18, it is immediately connected to the main tank 20. J1 compressed air is charged and pressure-accumulated at °C through a communication pipe 21 from the tank 11 to the nab tank 20. Note that a support arm 22 extending from the main body frame 6 to 1irJ:/j is provided on the front side of the fumarole branch 14.
- A router 23 is supported, which cuts the surface of the soil I11 on which the fumarole column 14 moves to a predetermined depth. Next, the operation of the above embodiment will be explained. The Aj1 soil improvement equipment 5 is attached to the rear of the tractor 1 via a three-point hinge (I of the tractor).
l” from the O shaft 1a to the compressor 10 via the power transmission system 12.
Rotational power is transmitted to the horn shaft 10a. When advancing, the C1 air blower 14 and the air jet 15 are plunged into the ground to a predetermined depth and are towed by the tractor 1. After that, the fumarole column 14 cuts the soil left and right and advances from h, and the air fumarole 15 advances horizontally in the deep layer of the karigami. During this process, during a predetermined timing interval M4 ("when operating the switch in the switch box 19a"), the solenoid valve 19 is surrounded by the solenoid valve 19.
When the is opened at a predetermined timing interval, the compressed air stored in the crack () is supplied to the supply air (1).
G, it passes through the ventilation hole 17 and is ejected forcefully upward from the fumarole hole 18. This ejection of high-pressure air causes cracks in the deep layer above the fumarole 18 (crack area C), as shown in Figure 4.
During the process, the compressed air is ejected in sequence at predetermined timing intervals, so that the crack area C continues to expand and soften the 4jl soil. During this work process, as mentioned above, the air emitted a lot! ), the weak points 25 are located on both sides of the upper end of the fumarole column 14, and extend in the front-rear direction, and the rear end side has a predetermined angle α with respect to the horizontal line L −1−, which is flat with the cultivated soil surface. (1) When the compressed air jet 115 is directed upwards, there is a gap between the compressed air jet 115 and the soil. Wing body 2
5, and the passage groove in the vertical direction J that is formed in the path of the fumarole branch 14 is also closed at the rear of the yq resting body 5. As a result, the upward blowing of the ejected air is prevented, and 1) the effect of cracks in the soil can be reduced to 5. ■ While the blade is moving to 1, the upper surface of the wing body 25 pushes up the uncultivated soil in the area II soil depth) + 'l'i as shown by the arrow in Figure 3. Due to the reaction force, the fumarole branch +4JjJ, air 11f1 gas 15 is pushed downward, and the air fume 15 is prevented from floating. This downward pushing action is in front of the air fume 15. The air fumarole 15 is regulated by the coulter 23 that advances on the surface of the soil 1, and as a result, the air fumarole 15 advances at a constant level through the deep layer of cultivated soil at a predetermined depth. From IjjikiJirf, 1-M1i, the depth of the Clara region C generated in the cultivated soil by air is constant. ■ Also, during the work, the uncultivated soil is pushed up by the upper surface of the above-mentioned wing body 2j). Due to the passage of the airfoil 2:i ((4) 1), the soil particles become dense and have the effect of preventing blow-out of the fumarole flow. is formed in the soil by the nozzle part 15I during the progress if the rear circle (-1 part 15a is formed with a large diameter) with respect to the nozzle part 151 at the tip as in the illustrated embodiment. The passing hole is closely spaced at the front end surface of the rear circular U portion 15a passing behind it.
This action also prevents the compressed air emitted from the blowhole 18 from blowing out through the passage hole J, and from this point as well, the cracking effect can be reduced. In the case of the illustrated embodiment, the wing body 25 has the following properties: flr>
The wing body 25 is attached to the lower end of the airfoil 14 (j14.J), but the attachment position of this wing body 25 is different from other aircraft moving through the soil. Jj left and right fumaroles 18.18
