Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manure discharge machine for automatically discharging manure discharged from livestock such as dairy cows to the outside of a livestock barn or the like.

[0002]

2. Description of the Related Art The excrement transporter described above has a structure in which an endless chain is circulated through a excrement transport passage laid inside and outside a livestock house. Then, a plurality of angle paddles arranged side by side in the chain are used to successively carry out the excrement and urine from the inside of the stall to the outside of the stall through the excrement discharge route.

In this manure discharge machine, a chain that circulates the above-mentioned manure discharge path is wound around a sprocket fitted to the output shaft of the speed reducer. Then, by rotating the speed reducer with an electric motor or the like, and rotating the sprocket fitted to the output shaft of the speed reducer in the circulation direction of the chain, the chain wound around the sprocket is moved to the manure discharge path. It has a structure in which it rotates in the direction of rotation of the sprocket.

In this manure discharge machine, the sprockets and chains are made of a wear-resistant material such as carbon steel or the like, which is a heat-resistant special forged steel. And, the sprocket and the chain are devised to prevent the wear as much as possible, but nevertheless, when the manure excrement machine is used for a long period of time, the tooth part or the tooth part of the sprocket is It cannot be prevented that the chain portion that meshes with is worn and the meshing between the sprocket and the chain is out of order. Further, it is impossible to prevent the occurrence of an accident such as the chain falling off from around the sprocket. Therefore, in the above-mentioned manure discharge machine, the sprocket and the chain are regularly replaced every 5 to 7 years.

[0005]

However, in the above-mentioned manure discharge machine, when the sprocket is to be removed from the periphery of the output shaft of the speed reducer in an attempt to replace the sprocket every 5 to 7 years. It has become rusty around the output shaft and fused together, and it is impossible to remove the sprocket from the output shaft periphery, or it takes a lot of labor to extract the sprocket from the output shaft periphery. , Was extremely difficult.

The reason why the sprocket adheres to the output shaft of the speed reducer and cannot be pulled out is that the above-mentioned manure excrement machine is used in a bad environment near manure, and therefore causes rust. This is because a large amount of water and salt contained in the sprocket always penetrates between the sprocket and the output shaft of the reduction gear to which it is fitted.

Therefore, when replacing the sprocket, the sprocket is melted and removed from the periphery of the output shaft, or the sprocket is extracted from the periphery of the output shaft using a large-scale hydraulic puller. In addition, the sprocket and the speed reducer for driving the sprocket may be arranged at a height of more than ten meters from the ground,
The sprocket replacement work had to be performed at a high place, and the sprocket replacement work was extremely dangerous.

Further, the sprocket is fitted around the output shaft of the speed reducer in close contact with a small tolerance, and when rust occurs between the sprocket and the output shaft, the rust causes the sprocket and the output shaft to rust. And easily fused together. Here, the reason why the sprocket is tightly fitted around the output shaft of the speed reducer with little tolerance is that when the sprocket rattles back and forth, left and right around the output shaft, the sprocket meshes with the chain wound around it. Is crazy. Then, the chain cannot be smoothly circulated by the sprocket.

The present invention can solve such problems.
Providing a manure transporter that prevents sprocket from rusting around the output shaft of the reducer and sticking together, allowing the sprocket to be pulled out easily and smoothly from the periphery of the output shaft where it is fitted without any trouble. The purpose is to do.

It is possible to prevent the work ring from being crushed around the inner peripheral surface of the shaft hole of the sprocket and the periphery of the output shaft during operation of the manure discharge machine to form a thin layer. Then, it is possible to prevent the sprocket from rattling back and forth, left and right, etc. around the output shaft of the speed reducer by forming a gap between the sprocket and the output shaft of the speed reducer to which the sprocket is fitted.

Further, in the excrement carrier of the present invention, the rust-preventive ring is formed from a resin layer coated around the output shaft into which the sprocket is fitted or on the inner peripheral surface of the shaft hole of the sprocket into which the sprocket is inserted. It may be

The resin layer has appropriate hardness and flexibility,
It has the property that it is easy to get familiar with the object pressed against it. Therefore, in this manure transporter, the sprocket is securely attached to the output shaft of the speed reducer without rattling through the resin layer coated around the output shaft of the speed reducer. Alternatively, the sprocket can be securely attached to the periphery of the output shaft of the speed reducer without rattling through the resin layer coated on the inner peripheral surface of the shaft hole of the sprocket. Then, the sprocket and the output shaft can be smoothly rotated together without rattling.

Further, the resin layer does not corrode and generate rust. Therefore, in this manure discharge machine,
The rust preventive ring made of a resin layer interposed between the sprocket and the output shaft of the speed reducer can reliably prevent the sprocket from rusting around the output shaft of the speed reducer and sticking together.

Further, in the excrement carrier of the present invention, the sprocket is fixed to the output shaft through a key and a key groove, and the sprocket is attached to the output shaft so that the sprocket does not fall out from the periphery of the output shaft. It is preferable to have a structure in which bolts are attached via.

In this manure discharge machine, the sprocket can be fitted onto the output shaft of the speed reducer through the key and the key groove so as to be rotatable integrally with the output shaft without slipping. Further, the sprocket can be fixed to the output shaft of the reduction gear by bolting it through the key. Then, it is possible to prevent the sprocket from falling off around the output shaft to which it is fitted.
