Description

[Detailed Description of the Invention] This invention assists the digging work of a subsoiler to reduce the digging resistance acting on the blade body, and
The present invention relates to a plow crushing device for a subsoiler, which blows out pressurized air toward the front of the blade of the subsoiler in order to crush the plow and improve drainage performance.

As the subsoiler moves forward while being towed by power agricultural machinery, the blade of the subsoiler overcomes the resistance of the upper soil and excavates the soil vertically and deeply. Reducing the digging resistance will improve the performance of the subsoiler. This is one of the important issues. Therefore, this invention provides a blade body 6 that is provided to hang down underground, and a blade body 6 that is provided so as to hang down underground.
This subsoiler is configured to crush the plowing platform by means of a digging body 5 attached to the lower part of the blade body 6, and the blade body 6 is provided in an inclined shape so that the lower part thereof is forward in the direction of travel than the upper part. At the same time, it is designed so that pressurized air is ejected toward the front of the blade body, which reduces digging resistance and makes it easier to maintain a certain depth, and further improves the crushing effect. It is.

Next, the specific structure will be explained based on an embodiment of a subsoiler configured so that the blade body vibrates in the direction of movement. A mast 2 is provided at the front part of the subsoiler frame 1 connected by 1b..., and is pivotally connected to the rear part of a power agricultural machine (not shown) by a top link 4 at the upper part and lower links 3 at the lower part. An excavation body 5 is fixed to the lower end of the blade body 6 that excavates the soil vertically and deeply. A groove forming body 7 is attached to the rear of the groove member 7 by a chain 7a. The upper part of the blade 6 and the rear part of the swinging arm 8 are combined to form an inverted L shape, and the swinging arm 8 is pivotally supported at an intermediate position by a support pin 9 protruding from the side surface of the longitudinal beam 1a. There is.

Bearing 10 loaded on subsoiler frame 1
The input shaft 11 of the subsoiler, which is pivotally supported by the
A part of the input shaft 11 is provided with an eccentric shaft 11a, and a drive shaft of the pressurized air generator 14 is connected to the rear end of the shaft 11.
The eccentric shaft 11a is supported via a bearing 15a on one of the upper spherical bearings 15b, 15b provided in pairs at the upper and lower parts of the swinging plate 15, and the lower spherical bearing 15b is supported at the tip of the swinging arm 8. is supported. Thus, the swing arm 8 is configured to vibrate up and down about the support pin 9 as the input shaft 11 rotates.

Next, the accumulator 14a of the pressurized air generator 14 is connected to the air conduit 14c inside the blade by the pipe 14b.
The pressurized air supplied from the pressurized air generator 14 is configured to be able to be ejected from the ejection port 14d disposed below the front surface of the blade body 6 through the pipe line 14c. In addition, the pressurized air is supplied to the blade body 6.
The liquid may be ejected from the front surface of the blade body 6 by piping on the side surface of the blade body 6.

In the subsoiler configured as described above, when the power agricultural machine (not shown) starts moving forward while driving the PTO shaft 12, the rotation of the eccentric shaft 11a causes the swing plate 15 to move the swing arm 8 up and down about the support pin 9. As a result, the blade 6 vibrates back and forth with the suction in an oblique position, and as a result, the blade 6 moves forward while efficiently digging underground. Also, the digging body 5 at the lower end of the blade body 6,
It moves forward while repeating back and forth movements, and assists the formation of the culvert 7b by the bullet-shaped work body 7 pulled by the digging body 5. During the excavation by the blade 6 and the digging body 5, the pressurized air supplied from the pressure air generator 14 continues to be ejected from the outlet 14d in front of the blade 6, causing cracks in the soil in front of the blade 6. By assisting the excavation of the blade body 6, the digging resistance acting on the blade body 6 is reduced, and furthermore, the compressed air once blown out is finally dispersed underground and rises as shown in Figure 1 B. As shown, since it escapes to the ground surface, the air not only swells and softens the soil in the process, but the air escape path 16 provides a good drainage channel for the surface water. The tiller crushing device for a subsoiler according to the present invention is configured as described above, and
The blade body 6, which travels while hanging down underground, is provided in an inclined manner so that the lower part thereof is more forward in the direction of travel than the upper part, so the digging resistance acting on the blade body 6 is small due to this inclined shape. As a result, the blade 6 can move easily, and the depth of the blade 6 is kept constant by well balancing the resistance acting on the digging body 5 at the bottom, and the blade 6 and the digging body 5 are able to crush the object. The plowing platform that is being used for this purpose is crushed into smaller pieces by the pressurized air that is ejected forward from the blade 6, making it particularly effective for growing root vegetables, and greatly improving drainage and ventilation. .
