Description

[Detailed Description of the Invention] A. Object of the Invention A. Industrial Field of Application The present invention aims to provide a halo.

B. Conventional technology and its problems Regarding this kind of technology that has been provided conventionally,
For example, there is a device disclosed in Japanese Patent Application Laid-Open No. 58-8910, which consists of a front puddling device, a suppressing plate installed at the rear close to the puddling device, and a suppressing plate installed at the rear away from the suppressing plate. It consists of a submerged cage.

Then, the soil is crushed using the plowing device in front.
The structure is such that after subduing the vessel with the suppression plate, submersion work is carried out using the submersion cage at the rear.

Since this device consists of a puddling device at the front and a submersion basket at the rear, it is inevitable that straw, weeds, compost, etc. will adhere to the rotating subsidence basket, which reduces the subsidence effect. I will do it.

B. Structure of the invention A. Means for solving the problem The present application attempts to solve the above-mentioned problems with the following structure.

That is, in the present application, a crushing rotor 3 having crushing claws 3A is rotatably provided in the front part of the frame 2, and a ring lattice 4 is rotatably provided in the rear part of the frame. It is a halo in which a swinging lattice-like sieve body 5 is attached to the front surface of the lattice 4.

B. Examples of the invention Examples will be described with reference to the drawings.

1 is a halo of the present invention.

Frame 2 is a horizontal frame 2 that is perpendicular to the direction of travel.
A side frame 2B is connected to both ends of the tractor in the form of a front gate, and support arms 2C and 2D for the three-point link of the tractor are provided on the side frame 2A to protrude in the traveling direction.

The crushing rotor 3 is composed of a shaft 3B rotatably attached to the side frame 2B, and a suitable number of crushing claws 3A planted on this shaft.

3C is a transmission device that rotates the shaft of a tractor.
Connected to the PTO shaft.

In this case, the direction of rotation of the shaft 3B may be normal or reverse.

The ring lattice 4 has an appropriate number of rings 4A arranged at predetermined intervals 4.
B is provided, and the whole is connected to form a cage shape using a connecting horizontal bar 4C arranged inside the ring 4A.

4D is a side plate attached to both ends of the ring lattice 4, and this side plate 4D is used to support the ring lattice support frame 6.
It is rotatably mounted on the

Therefore, this frame 6 consists of a horizontal frame 6A parallel to the horizontal frame 2A, and left and right frames 6B that are connected downwardly at both ends of the horizontal frame.

A shaft 4E protruding outward from the side plate 4D is rotatably supported by the left and right frames 6B.

As mentioned above, the lattice-like sieve body 5 is disposed on the front side of the ring lattice 4 with a small interval from the ring lattice 4, and its structure is such that the side passages ( Appropriate number of rods 5A configured in the shape
are connected in parallel.

In this case, the position of this rod 5A is the same as that of the ring 4A.
It is configured to be located at the center of a predetermined interval 4B.

Therefore, this sieve body 5 is designed to swing relative to the ring grid 4.

There may be various structures for this swinging.

For example, when attaching a rod 5A made of a material with some elasticity to a horizontal frame 6A as shown in FIG. 6, a coil portion 5A is attached to the upper end of the rod 5A as shown in FIG.
A' may be formed and this coil portion is attached to the horizontal frame 6A.

In these cases, the elasticity of the rod vibrates due to vibrations during work.

In addition, there are cases where the device is forcibly swung.

That is, referring to FIG. 8, when the horizontal connecting rod 5B connecting the upper end of the rod 5A and the shaft 4E of the ring lattice are connected by the crank mechanism 7, the horizontal connecting rod 5B and the spring as shown in FIG. 8, in the case of a combination of the horizontal connecting rod 5B and the cam 9 as shown in FIG. 11, the claw body 10 connected to the horizontal connecting rod 5B as shown in FIG. In some cases, it may be configured to be connected to and disconnected from the section.

In this case, the roller 4C' is rotatably fitted to the horizontal bar 4C.

In addition to the above-mentioned crushing rotor, the crushing rotor 11 shown in FIGS. 14 and 15 may also be used.

That is, in this rotor 11, disks 11B having a predetermined angle are fixed to a rotatable shaft 11A at a predetermined interval, and crushing claws 11C are radially fixed to the disks 11B.

12 is a sled body for erasing tractor tire marks.

Moreover, it can be used by being attached to the tailor 13 as shown in FIG.

14 is a lifting frame, and a depth adjustment handle 15
It is configured so that it can be raised and lowered by rotating.

Reference numeral 16 denotes a pressure plate, which is supported by a support rod 16A so as to always act downward.

C Effect Explain along with the effects.

C Effects of the Invention Since the present invention is configured as described above, it produces the following effects.

a The soil crushed by the soil crushing rotor passes through the sieve body and is scattered in the direction of the ring grid.

As a result, the soil clods that do not pass through the sieve body fall on the front surface of the sieve body, and the fine soil clods that have passed through the sieve body reach the ring grid and are processed by the ring grid.

Then, the fine soil clods that have passed through the sieve body are stacked on top of the coarse soil clots that have fallen onto the front surface of the sieve body without passing through the sieve body.

In other words, it is possible to form a two-layered soil structure with coarse soil clods in the lower layer and fine soil clods in the upper layer.

b For moist soil, rod 5 in the sieve body
Although there may be a phenomenon in which the bar 5A gets stuck between the rings A and the rod 5A or between the rings 4A in the ring lattice, the rod 5A is configured to be located between the rings 4A and the rings 4A. At the same time, since the sieve body is oscillated, it is possible to prevent soil from adhering to the sieve body.
