Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side plate of a crushing earth wheel attached to a cultivator towed by a tractor.

[0002]

[Technical background]

 In general, work using a crushing wheel is mounted on a cultivator towed by a tractor, and rotates by the resistance to the ground contacting the tractor when it is towed and the weight of the crushing wheel. The scratching claw precedes the crushing wheel, and the purpose is to crush the soil in the field and crush the large-scaled lump of soil with the moving crushing wheel.

[0003]

[Prior Art]

 The crushed soil wheel that is driven by a tractor has a small number of crushed soils depending on the soil quality of the field to be used, but there are multiple types of crushed soil, but the usage and results are the same.

[0004]

[Problems to be solved by the device]

 In order to improve the performance of the tractor itself and to expect a high efficiency of the soil breaking work, there is an increasing tendency to operate at high speed in recent years. Before crushing, there occurs a phenomenon of scattering 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 crushed earth ring, and further, a small-sized soil mass is earthed and covered, which gives a great influence. Will result.

[0006] 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 plant that has entered the latter half of the growing stage 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 that can be easily attached and detached to both sides of the crushing earth wheel if necessary. Is.

[0008] Still another object is to prevent trampling a petiole of a large plant, which is close to a recumbent state, with 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 stop it, it is an object to provide a standing wing piece on the outer side of the removable side plate so that the petiole of the recumbent state can be supported.

[0009]

[Means for Solving the Problems]

 As a means for achieving the above object, the present invention supports both ends of a pivot projecting from the central portions of both side plates of a shredded earth wheel at both lower ends of a substantially U-shaped support frame, and A side plate having a shape capable of covering most of the side plate is provided with a fixing hole which can be fitted with a nut for fixing the end of the pivot of the crushing earth wheel protruding to the outside of the supporting frame, and the fixing hole is formed at the center. A circular arc-shaped long hole is formed on a circle having a radius of distance L, and is located outside the supporting frame with a distance L ′ of the same dimension as the distance L above the pivotal support position of the pivot. An externally oriented bolt is provided on the side, and the nut is fitted and inserted. The bolt is passed through the arc-shaped long hole of the side plate, and the protruding nut is screwed into the projecting tip so that it can be detachably attached to the support frame of the earth-crushing wheel. It is composed in this way.

On the outer surface of the side plate, oblique standing blades having a low front and a high rear are provided so as to project in the lateral direction.

[0011]

[Action]

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

[0012] That is, in the season when the soil crushing wheel is used, that is, before and after sowing of a crop, the soil condition along with the initial cultivation such as the growing condition of the crop, the middle cultivation, and the after cultivation, or other than these main purposes, It also has a secondary purpose of being used as a load to be applied to the crushing wheel.

In the case of crushing work that does not require the side plate, the use of the side plate unnecessarily leads to waste of work for the purpose of mounting, unnecessary power load on the tractor, and eventually to reduction of work efficiency. There is a risk of this, so the desorption method is also desirable for that purpose.

Although the above-described object can be achieved by mounting the side plate of the present invention, as described above, the side plate is removed in order to avoid a disadvantageous action when the side plate is unnecessary. Therefore, the frequency of the desorption operation is increased, and thus the ease of the operation is required.

The essential configuration provided as a means for mounting on one side plate is the same as a nut with which a nut for fixing the pivot shaft for supporting the crushing earth wheel and the supporting frame can be fitted to the support frame of the crushing earth wheel device. The fixing hole and the arcuate elongated hole formed on a circle having a radius L around the fixing hole and having an arbitrary distance L are provided. The side plate mounting means of the present invention is constructed by projecting a bolt from a position on the outer surface of the shaft that is separated from the pivotal support point by a distance L ′ equivalent to the distance L.

A nut is fitted in the fixing hole in the side plate, a bolt protruding from the support frame is inserted through the arc-shaped elongated hole, and a fixed nut is screwed on the end portion of the bolt protruding from the arc-shaped elongated hole. It fits and tightens firmly.

The reason why the engagement hole into which the bolt is inserted is an arc-shaped elongated hole is that the support frame can be in various standing states, and that the side plate can be selected in an optimum state depending on its shape. The purpose is to do.

Further, the supporting wing pieces provided on the outside of the side plate are scooped up and protected only at least when the crushing earth wheel is passed so as not to trample the petiole of the lying plant outside the vegetation with the crushing earth wheel. To do.

[0019]

【Example】

 Next, the embodiment of the present invention will be described with reference to the drawings. Both ends of the pivots 3 projecting from the central portions of the side plates 2 and 2 of the crushing earth wheel 1 are pivotally supported at both lower ends of a substantially U-shaped support frame 4. Then, the side plate 6 having a shape capable of covering most of the side plate 2 of the crushing earth wheel 1 is fitted and inserted into the nut 7 for fixing the end portion of the pivot 3 of the crushing earth wheel 1 projecting to the outside of the support frame 4. A fixing hole 8 that can be formed is formed, and an arcuate elongated hole 9 is formed on a circle centered on the fixing hole 8 and having a radius of the distance L. The axis of the pivot 3 is provided outside the support frame 4. A bolt 10 directed outward is provided above the supporting position at a position separated by a distance L ′ having the same dimension as the distance L, and the bolt 10 is inserted into the arc-shaped elongated hole 9 of the side plate 6 into which the nut 7 is fitted and inserted. A fixed nut 11 is screwed onto the protruding and penetrating tip, and is detachably attached to the support frame 4 of the crushing earth wheel 1. It is those formed by wear way.

On the outer surface of the side plate 6, oblique standing wing pieces 12 having a low front and a high rear are provided so as to project in the lateral direction.

The supporting frame 4 rotatably and pivotally mounted on the crushing earth wheel 1 configured as described above is attached to the cultivator 20 through the connecting member 13.

If the above-mentioned fragmentation wheel device is described in more detail, as an example thereof, it is generally mounted on a cultivator 20, and a mid-bone beam 21 of the cultivator 20 pulled by a tractor (not shown). In most cases, the chuck bracket 23 for mounting the scratching claw 22 is mounted together with the chucking claw 22.

The claws 22 to be mounted on the cultivator 20 are of various types according to the work form and its contents, from a single instrument to a plurality of claws 22 being used at the same time, and a chuck bracket for mounting the claws 22. The 23 forms also vary.

The illustration of the embodiment is one example, in which the scraping claw 22 is attached to the mid-bone beam 21 via the chuck bracket 23 with the safety bolt 24 and the fulcrum bolt 25.

[Effect of the device]

 As described above, the present invention is equipped with a side plate on the side surface of the crushing wheel so that the scattering phenomenon of the clod caused by the trampling action of the large lump during the crushing work can be performed in the side plates attached to both sides of the crushing wheel. In addition, it is effective to prevent damage to the vegetation parallel to the traveling direction of the soil crushing wheel and to perform intact soil crushing work.

Even when the growing period of the plant in the field where the crushing work is performed is in the later stage and the large-sized outer petiole is close to lying on the ground, as the crushing device progresses, The standing winglets provided on the outer surface of the plate scoop up the lateral petiole from below to erect it, which has the effect of promoting the standing of the lateral petiole and preventing the trampling phenomenon caused by the crushing earth wheel.

[0027] These side plates are attached to and detached from the crushing device by a simple structure in which only one nut can be attached / detached to / from one side plate. This is an effect that any person can easily carry out the desorption operation conforming to the above in a short time without requiring any skill.
