Description

DETAILED DESCRIPTION OF THE INVENTION This invention has a so-called structure in which a crushing blade suspended in the ground is vibrated back and forth in order to crush the hardened plow bed in the lower layer of the ridge and to improve air permeability and water permeability. This is an excavation device that uses a vibrating subsoiler to dig up the roots of roots and leaves, etc. By using the vibration mechanism of this vibrating subsoiler, the soil around the roots is vibrated to float. The purpose of this paper is to propose an excavation device that facilitates the digging of roots.

Next, the structure of the present invention will be explained based on one embodiment shown in the drawings. As shown in FIG. The left and right blade bodies 1a, la are provided with cutting blades lb, 1b, and
Chisel-like excavating bodies 2 and 2 with triangular tips, respectively,
It is fixed to the lower part of the blade bodies 1a, 1a.

The cross section is an isosceles triangle, and the length is the blade body 1a, 1
Forming an excavated pillar body 3 slightly longer than the left-right distance of a,
At the rear of each excavating body 2, one end of a flexible body 4 such as a chino or a wire is attached to the blade 1a at the rear end of a flexible body 4 on the apex side of the isosceles triangle of the excavating column 3. When the vicinity of both left and right ends are engaged and the lower parts of the blades 1a, 1a are moved forward while hanging down into the ground as described later, the excavation column 3 is horizontally moved in the left and right direction behind the blades 1a, Ia. so that it is towed in a similar manner.

Then, the mounting seat 1d protruding from the center of the horizontal rod 1c of the vibrating blade 1 formed in this way is attached to a mounting frame that is pivotally supported between the frames 5, 5 of the vibrating subsoiler as shown in Fig. 1 and vibrates back and forth. The structure of the vibrating subsoiler shown in the figure has hitch pins 8, 8 protruding left and right from the lower end of the mast 7, and two elongated plates arranged horizontally. The front ends of the frames 5, 5 thus formed are attached to the inner lower end of the mast 7.7, and the brackets 9, 9, which are provided with upper and lower shaft supports 9a, 9b, respectively, are attached to the inner surfaces of the frames 5, 5, and the mounting frame 6 is attached. While the shaft support 6a is inserted between the brackets 9, 9, the mounting frame 6 and the vibrating blade 1 are placed in a vertical plane along the frames 5, 5 around the pin shaft 10 into which the shaft support 6a, 9b is horizontally inserted. A drive shaft 11 is formed so as to be rotatable, and is disposed in the longitudinal direction inside the frames 5, 5.
, 13, and a disk cam 14 with an oval profile is attached to the rear end of the drive shaft 11, and a crank 15 formed in an L shape is mounted.
The base of the crank 15 is fitted into the upper shaft support 9a of the bracket 9, and the crank 15 is pivoted by the pin shaft 16 so as to be rotatable in a vertical plane parallel to the rotation plane of the vibrating blade 1. At the front end of the horizontal arm portion 15a, a roller 17 which can be in rolling contact with the disc cam 14 is pivoted perpendicularly to the arm portion 15a, and
A roller 18 is pivotally attached to the vertical arm 15b of the crank 15 so that it can rotate parallel to the pin shaft 16, and the frame 5
The compression spring 20 interposed between the spring receiver 19 erected at the rear of the frame 6 and the upper end of the mounting frame 6 keeps the contact plate 21 attached to the front upper part of the mounting frame 6 in constant contact with the roller 18. The rotation of the disc cam 14 causes the crank 15 to move towards the pin shaft 1.
The vibrating blade 1 is formed to vibrate back and forth by vertically swinging around the power agricultural machine 22, and the hitch pins 8, 8 are fitted into the lower link 23.
Top link 24 pivoted to the rear upper part of this power agricultural machine 22
The upper part of the mast 7 is pivotally connected to the PTO shaft 2 of the power agricultural machine 22.
This vibrating subsoiler rotates and drives the drive shaft 11 via a flexible transmission shaft 26 connected to the vibration blade 1, and the rear parts of the frames 5, 5 are supported by tail wheels 27 and 27. 1a and Ia are suspended underground and held.

Since the moat device according to the present invention is configured as described above, the blade 1a moves underground while being towed by the power agricultural machine 22.
, la, and the digging column 3 horizontally installed horizontally from side to side at the lower rear of the blade bodies 1a and la serve as pin shafts for the crank 15 that swings back and forth with the rotation of the PTO shaft 25. It will oscillate around 10 in the front and back direction.

At this time, the Horishin body 2 vibrates deep underground.
, 2 are capable of crushing hardened tillage into small pieces with little resistance, and the left and right blades 1 a
Since rla has a thin blade shape in the direction of movement and vibrates back and forth, its forward resistance can be made extremely small.

The excavating column 3, which moves horizontally behind the excavating body 2゜2, moves so as to spread the nearby plowing plate upward and downward, but it is vibrated back and forth by the blade bodies 1a and la. This excavation column 3, which has been given a , the plowing platform above the excavation column 3 is crushed and softened over a wide range.

Therefore, since the roots of crops in the vicinity of which the excavation column 3 advances are crushed by the plowing plate in this way, it is extremely easy to dig out the roots after crushing. When a small shaking motion is applied to the board, the thin roots extending from the roots of the crop are separated, reducing the resistance to pulling out the roots when digging up the roots.

Furthermore, since the excavation column 3 is connected by the flexible bodies 4, 4, when the excavation column 3 is pulled up from underground, the excavation column 3 is The triangular tip portion 3 always takes a posture consistent with this pulling direction, which reduces pulling resistance and also has the advantage of facilitating the pulling operation.

As described above, the device of the present invention has the excellent effect of efficiently crushing the plowing plate near the roots of crops over a wide range using a conventionally used vibrating subsoiler, and making rooting work easier. It is something.
