[0002]

[Technical Background] In general, work using a crushing wheel is mounted on a cultivator towed by a tractor, and is rotated by the resistance to the ground in contact with the tractor when it is towed and the weight of the crushing wheel. The claw attached to the is ahead of the crushing earth wheel, and the purpose is to crush the field soil and crush the large-scaled lump of soil with the crushing earth wheel moving backward.

[0003]

2. Description of the Related Art A crushing earth wheel driven by a tractor has a small number of crushing outer circumferences depending on the soil quality of the field to be used. .

[0004]

[Problems to be solved by the invention] In order to improve the performance of the tractor itself and to expect a high efficiency of crushing work, there is an increasing tendency to operate at high speed in recent years. Before crushing a large lump of earth with a crushing earth wheel, a phenomenon occurs in which it is scattered in a direction orthogonal to the crushing earth wheel.

When such a phenomenon occurs, it hits or falls on a growing plant that is planted in parallel with the traveling direction of the crushing earth wheel, and further, a small-sized soil mass is earthed and covered, which gives a great influence. Will result.

In addition, in the ridges adjacent to the traveling direction of the crushing earth wheel, a situation in which the outer petiole of a large-scale plant that has entered the latter stage of growing is trampled by the crushing earth wheel also occurs daily.

In order to avoid the above-mentioned inconvenience, the present invention aims to prevent lateral scattering of the clod by attaching side plates which can be easily attached and detached to both sides of the crushing earth wheel if necessary. Is.

[0008] Still another object is to prevent the petiole of a large plant close to a recumbent state from being trampled by a crushed earth wheel when there is a plant in the late stage of growth adjacent to a ridge intended for crushed soil. In order to do so, it is an object of the present invention to provide a standing wing piece on the outside of the detachable side plate so that a petiole of a recumbent state can be supported.

[0009]

As a means for achieving the above-mentioned object, the present invention proposes, as means for achieving the above-mentioned object, that both ends of a pivot shaft projecting from the central portions of both side plates of a crushing earth wheel are both lower end portions of a substantially U-shaped support frame. A fixing hole that can be fitted with a nut that fixes the end of the pivot of the earth breaking wheel that protrudes outside the support frame is formed in the side plate that is supported by At the same time, an arcuate elongated hole is formed on a line having a distance L as a radius with the fixing hole as a center, and the same size as the distance L is provided outside the supporting frame on the outer side of the supporting frame. A bolt pointing outward is provided at a position through a distance L ', and the bolt is passed through an arc-shaped long hole of a side plate to be fitted and inserted into the nut, and a fixing nut is screwed into a protruding tip to support a grounding wheel. It is configured so that it can be detachably attached to the frame.

On the outer surface of the side plate, oblique standing wing pieces having a lower front and a higher rear are projected in a lateral direction.

[0011]

The side plate of the earth-crushing wheel of this invention is premised on being detachable from the earth-crushing wheel device pivotally supported by the support frame.

[0012] That is, the season when crushed earth wheels are used, that is, before and after sowing of crops, initial cultivation such as growing condition of crops, middle cultivation,
Along with post-plowing, etc., it has soil properties, or in addition to these main purposes, there is also a sub-purpose used as a load to be applied to the crushing earth wheel.

In the case of crushing work that does not require the side plate, use of the side plate unnecessarily causes waste of work for the purpose of mounting, unnecessary power load on the tractor, and eventually,
Since the work efficiency may be reduced, the desorption method is also desirable for that purpose.

Although the above-mentioned object can be achieved by mounting the side plate of the present invention, as described above, the side plate can be removed in order to avoid the disadvantageous action when the side plate is unnecessary. And therefore,
Since the frequency of the desorption operation becomes high, the ease of the operation is required.

An indispensable structure provided as a means for mounting on one side plate has the same shape as a nut with which a nut for fixing the pivot and the supporting frame of the crushing earth wheel to the supporting frame of the crushing earth wheel device can be fitted. Of the fixing hole and an arcuate long hole provided on a circle having a radius L at an arbitrarily set distance L centered on the fixing hole. The side plate mounting means of the present invention is configured by projecting a bolt from a position on the outer surface that is separated from the pivotal support portion of the pivot by a distance L ′ equivalent to the distance L.

A nut is fitted in the fixing hole in the side plate, a bolt projecting from the support frame is inserted through the arc-shaped elongated hole, and a fixing nut is screwed to the end of the bolt projecting from the arc-shaped elongated hole. And firmly tighten it.

The reason why the engaging hole through which the bolt is inserted is an arc-shaped elongated hole is that the support frame can be in various standing states, and the side plate can be selected in an optimum state depending on its shape. Is intended.

Further, the supporting wing piece provided on the outside of the side plate scoops up only at the time of passing through the crushing earth wheel so as not to trample the petiole of the vegetation outside in the recumbent state with the crushing earth wheel. To do.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the drawings, an embodiment of the present invention will be described. To a side plate 6 that is supported by a portion and can cover most of the side plate 2 of the crushing earth wheel 1, and a nut 7 that fixes the end of the pivot 3 of the crushing earth wheel 1 that protrudes to the outside of the support frame 4. A fixing hole 8 that can be fitted and inserted is formed, and a distance L is centered on the fixing hole 8.
A circular arc-shaped long hole 9 is bored on a circle line having a radius of, and is located outside the support frame 4 at a position above the pivotal support position of the pivot 3 with a distance L ′ of the same dimension as the distance L. A support frame for the earth-crushing wheel 1 is provided by providing a bolt 10 that points outward, and inserting a fixing nut 11 into the protruding tip of the bolt 10 that penetrates the arc-shaped long hole 9 of the side plate 6 into which the nut 7 is fitted and inserted. 4 can be detachably attached.
