Agricultural paddy field straw smashing and field-returning device

Abstract

The invention discloses an agricultural paddy field straw smashing and field-returning device, and belongs to the technical field of agricultural equipment. The agricultural paddy field straw smashing and field-returning device comprises a moving seat, wherein a cavity is formed in the middle of the moving seat in a penetrating mode; a guide seat is fixedly arranged on the rear wall of the moving seat; an impeller is arranged on the rear part of the left side of the cavity; a shaft center is coaxially and fixedly connected to the middle of the impeller; the left end of the shaft center penetrates through the left wall of the cavity, extends to the outside and is coaxially and fixedly connected with a driven wheel; a driving wheel is arranged in front of the driven wheel; a transmission belt is connected between the driven wheel and the driving wheel; a rotating shaft is coaxially and fixedly connected to the middle of the driving wheel; the right end of the rotating shaft sequentially penetrates through the left wall of the moving seat and the right wall of the cavity, extends to the outside and is coaxially and fixedly connected with an electric motor B; a filter plate is fixedly arranged in the cavity relative to the position behind the rotating shaft; and a smashing assembly is arranged in the middle outside the rotating shaft. The agricultural paddy field straw smashing and field-returning device provided by the invention can perform integrated operation of harvesting, smashing and field-returning on straws so as to be beneficial to saving a large amount of labor consumed by a farmer for harvesting the straws, and is convenient, rapid, safe and flexible.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, and more specifically, relates to a device for crushing and returning agricultural rice field straw. Background technique [0002] After the rice field is harvested, a lot of straw will be produced. Farmers mostly use fire to deal with the straw or cut off the top and leave the root to rot. Among them, the fire method is due to the pollution of the atmosphere and the Fire hazards are banned by the country, and it will be very time-consuming and labor-intensive to cut off the top and leave the roots, and it is a big problem to deal with the cut stalks. [0003] After retrieval, the patent with the publication number of CN111802080A discloses a device for crushing and returning rice field straws for agricultural use, which collects straws such as rapeseed straws in rice fields by means of motor-driven pulley transmission, collects them in a crushing box, and crushes them. The crushi...

AI Technical Summary

Problems solved by technology

Although the existing device solves the problem of subsequent processing of straw, it still requires farmers to harvest the straw and put it into the device for crushing before crushing the straw, which will still generate a large workload and consume a lot of labor. Furthermore, the existing device Farmers need to push the device forward while putting the straw into the device to achieve the effect of evenly returning the crushed straw to the field. The operation is difficult and the flexibility is low. In addition, the crushing teeth in the existing device have a horizontal structure. Falling into the crushing box in a horizontal state will cause the device to fail to crush the straw normally, and due to the blocking effect of the screen, this part of the straw will accumulate more and more, causing the device to be stuck and unable to continue to work. In view of this, we A device for crushing and returning rice straw to the field for agricultural use is proposed
