Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer spreaders, in particular to a side-throwing fertilizer spreader. Background Art

[0002] A fertilizer spreader is an agricultural machinery equipment that throws fertilizers such as agricultural manure and dung into the fields. Traditional fertilizer spreaders transport fertilizers to the throwing mechanism through a chain plate conveyor. This transport structure has poor sealing performance, and animal liquid manure containing a lot of urine is likely to leak outside the hopper, causing waste and pollution. Moreover, the throwing mechanism can only throw fertilizers backward and cannot meet the special needs of farms such as breeding farms to throw liquid manure containing animal urine into the fields on the side of the machine. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a side-throwing fertilizer spreader that transports manure to the throwing mechanism through a spiral conveyor. The box body has good sealing performance, and the purpose of throwing liquid manure containing animal urine into the fields on the side of the fertilizer spreader can be achieved.

[0004] The technical solution of the present invention is realized as follows: A side-throwing fertilizer spreader includes a box body, wheels, a front cover, a towing bar, an input shaft, an upper cover, a rear flange, an upper spiral shaft, a lower spiral shaft, a gate, an oil cylinder, a throwing shaft assembly, a driving wheel, a throwing wheel, a large transmission wheel, an upper sprocket, a lower large sprocket, a lower small sprocket, a small transmission wheel, and a transmission shaft. The wheels are arranged on the lower side of the box body, the towing bar is arranged at the front end below the box body, the front cover is fixed to the front end of the transmission box of the box body, the upper cover is fixed to the upper end of the transmission box of the box body, the gate is arranged in the track groove at the discharge port of the box body, and both ends of the oil cylinder are hinged to the box body and the gate respectively. The rear flange is fixed to the tail end of the box body. The front and rear ends of the upper spiral shaft and the lower spiral shaft are connected to the front panel and the rear flange of the box body through bearings. The input shaft is connected to the lower front side of the transmission box of the box body through a bearing. Two driving wheels are arranged in the transmission box and connected to the input shaft. The throwing shaft assembly is connected to the discharge port position of the box body through a bearing. A throwing wheel is connected to the front end of the throwing shaft assembly. The throwing wheel and the front driving wheel are driven by a chain. The transmission shaft is connected to the transmission box through a bearing. A large transmission wheel and a small transmission wheel are fixed to the transmission shaft. The large transmission wheel and the rear driving wheel are driven by a chain. The lower large sprocket and the lower small sprocket are connected to the lower spiral shaft. The lower large sprocket and the small transmission wheel are driven by a chain. The upper sprocket is connected to the upper spiral shaft. The upper sprocket and the lower small sprocket are driven by a chain.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention uses a spiral conveyor to transport fertilizers, and the box body has good sealing performance, so the manure is not easily leaked; 2. The throwing structure of the present invention is on the side of the box body, which can meet the special needs of throwing manure into the fields on the side of the machine; 3. The present invention uses chain drive, which can transmit a large load and has high transmission efficiency. Brief Description of the Drawings
