Description

[Detailed description of the invention]

[Industrial Application Field 1] The present invention causes compressed air to be blasted into the deep layer of the soil to create fissures in the soil. This relates to soil improvement equipment that supplies soil. [Prior Art] This type of soil improvement device was previously proposed by the present applicant, for example, in Japanese Patent Application Laid-open No. 58-5660 (Full-hole type soil improvement device).
A manually operated type is known, as described in JP-A No. 58-126701 (11-panel inflatable (device), Japanese Patent Application Laid-Open No. 58-216601 (self-propelled vehicle equipped with automatic deep tilling device), etc. In the former Japanese Patent Application Laid-open No. 11-B58-5660 (Full-type Soil Improvement Im), the soil conditioner is moved manually and the fumarole operation is performed manually in the moving position area, whereas the latter's special feature -b described in JP-A-58-126701 (Plowing plate expansion and softening), JP-A-58-216601 (Self-propelled vehicle equipped with automatic plowing depth device), etc. is a soil improvement machine that is a working part. Since the main body (@air device) is mounted on a self-propelled vehicle such as a tractor, it is easy to move, and the capacity of the compressor, etc.
The capacity of the air tank can also be increased. but,
In all of the previous systems, the self-propelled vehicle temporarily stops running at the fume position and operates the fume by moving the fume 'viv1 up and down in the stopped state. It is necessary to run and stop frequently, and although it is easier to move than the former manual type, the improvement in work efficiency is not very promising. Well, all of the conventional ones have blowholes at the tip.
This is a type of hollow rod-shaped fumarole pipe that is inserted into the soil to emit compressed air. Not only does it require a special mechanism (drive-pull mechanism),
It was not suitable for renewing grasslands on pastures or golf courses.
It is said that amending the surrounding soil by cutting off a certain amount of old roots in the soil while expanding and softening the surrounding soil promotes the growth of new roots and has a remarkable effect on regeneration. There is also a problem in usage that the above-mentioned effects cannot be expected.

[Object of the Invention] In view of the above-mentioned problems, the present invention has been devised to make it possible to atomize f-compressed air into the soil while the self-propelled vehicle is running, and to improve the work efficiency. The purpose of this invention is to provide a self-propelled air soil improvement device that can achieve the above-mentioned root cutting effect by making angular cuts. [Configuration 1 of the Invention] In order to achieve this object, the present invention equips a self-propelled vehicle with a rotary plate body that is driven to rotate around a horizontal axis perpendicular to the traveling direction and cut into the soil. , A blowhole is provided at the peripheral edge of this rotating plate, and the blowhole is installed at the center of rotation of the plate.
When the air supply passage is connected to a compressed air supply source installed in the vehicle, and the blowhole of the rotary plate is cut into the ring, The present invention is characterized in that a valve means is provided on the compressed air supply system to blow compressed air into the soil from the blow hole. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a self-propelled vehicle, and this self-propelled vehicle 1 is equipped with a pair of left and right front wheels 3 and rear wheels 4 at the front and rear parts of a vehicle body 2.

As shown in FIG. 5 and FIG. 171) has four thin film vignettes. The rotary plate 17 has concavities and convexities in a substantially cross shape when viewed from the side, and the distal end of each protrusion has a rearward direction as shown in FIG. 3 with respect to the rotational direction indicated by the arrow in FIG. A fumarole 21 is open inside the tube. The outer circumferential edge of the tooth 6 facing toward the axis of the rotary plate 17 from the position where the air hole 21 opens is located on the outer surface of the outer circumference where high-pressure air ejected from the fumarole hole 21 is blown toward the ground along the rotary plate 17. A wide width 81117d is formed to prevent the blowing from being handled, but the shape and position of the prevention member may be changed as appropriate.

In the fume type tilling device having such a configuration, when the self-propelled vehicle 1 is running, the transmission case 14 is
When it is lowered to the working position by a and the rotary plate 11 rotates J,
Only narrow plowing marks remain on the soil surface, and when the protrusion of the rotary plate 17 in the soil is almost at its lowest point, the microswitch 19 opens the solenoid valve 24 and compressed air is blown out. It creates cracks over a wide range of deep soil and supplies air (oxygen).
It has a positive effect on the roots of Song trees and crops. The compressed air in the sub tank 23a is supplied to the solenoid valve 24.
When the air is discharged through the main tank 23, it is replenished one after another, and compressed air at a predetermined pressure is continuously ejected from each blowhole 21. In addition, the high-pressure air ejected from the fumarole 21 expands and softens the soil on the front side in the direction in which the machine moves, so the cutting resistance of the rotary plate 11 into the soil is reduced, making deep plowing easier. Furthermore, when the soil conditioner of this embodiment is used to renew grass in pastures and golf courses, the rotation of the rotary plate 17 cuts off the old roots of the grass and grass, and furthermore, the soil around the roots is loosened by the fumes. It becomes swollen and soft, promoting the growth of new roots, resulting in a remarkable renewal effect. Effects of the Invention As explained above, according to the self-propelled air soil improvement device of the present invention, blowholes are formed at the peripheral edge of the rotary plate that rotates and passes through the soil as the self-propelled vehicle travels.
