Rice straw cutting, spraying and returning apparatus

Abstract

The invention relates to the field of agricultural tools, and particularly relates to rice straw cutting, spraying and returning apparatus. The apparatus comprises a shell, a cutting device, a spraying device and a pressing device; the shell is of a hollow rectangular structure; the cutting device and the spraying device are both arranged in the shell; the cutting device is positioned above the spraying device; the pressing device is positioned above the cutting device; the cutting device comprises a cutting motor, a rotating shaft and a plurality of cutting saw blades; the rotating shaft is horizontally arranged in the shell; two ends of the rotating shaft respectively penetrate through the outer wall of one side of the shell and extend to the outside of the shell; two joints of the rotating shaft with the shell are respectively provided with a bearing; one end of the rotating shaft is provided with a driven wheel; the cutting motor is positioned below the driven wheel; the cutting motor is fixedly connected with a first fixing plate; the output shaft of the cutting motor is also provided with a driving wheel; and all the cutting saw blades are fixedly arranged on the rotating shaft in a straight arrangement mode. The apparatus provided by the invention can be used to solve the problem that farmers cannot properly treat straw.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a device for cutting and spraying rice stalks and returning them to the field. Background technique [0002] Straw is the general term for the stems, leaves and spikes of mature crops. It usually refers to wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops, which are usually the remaining part of coarse grains after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by a high crude fiber content of 30%-40%, and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by livestock such as ruminants such as cattle and sheep. However, after harvesting rice in some mount...

Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a device for cutting and spraying rice stalks into the field. The straw is put into the casing through the feeding hopper, and the cutting motor drives the cutting saw blade on the rotating shaft to put the straw into the casing. For cutting, the limit plates on both sides of the cutting saw blade restrict the straw so that the straw must be cut by the cutting saw blade before falling. When the cutting saw blade cuts, the pressing motor drives the rotating disc to rotate, and the connecting rod on the rotating disc makes The pressing plate reciprocates back and forth along the vertical direction of the slide rail, pressing the straw down to make the straw cut better. After cutting, the chopped straw will fall into the spraying device along the gap between each cutting saw blade In the hopper, it falls into the spray pipe through the connecting pipe, and the spray fan blows the straw that falls into the spray pipe into the field through the wind, which solves the problem that farmers cannot properly handle the straw
