straw propulsion device

Abstract

The invention discloses a straw pushing device which comprises a cylinder body, a hydraulic cylinder and a compression device. One end of the cylinder body is connected with the hydraulic cylinder, the other end of the cylinder body is connected with the compression device, a feeding port is formed in the side wall of the cylinder body, a discharging port is formed in the other end of the compression device, a piston for pushing straw bundles is arranged in the cylinder body, and the piston is connected with the hydraulic cylinder through a connecting rod. The compression device is a barrel, a conical barrel is arranged in the barrel, a compression cavity is formed inside the conical barrel, a discharging port is formed in the small-diameter end of the conical barrel, the large-diameter end of the conical barrel is connected with the inner wall of the barrel, an air channel is formed between the conical barrel and the barrel, an air taking interface is formed in the barrel and is communicated with the air channel, and the straw pushing device can discharge out air in air-dried straw bundles and improve the carbonization rate.

Description

technical field [0001] The invention relates to the technical field of straw processing, in particular to a straw propulsion device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Now a large amount of straw is produced in agricultural production. Traditional straw is mainly disposed of by incineration, which pollutes the air and fails to obtain effective benefits. Straw carbonization is an effective application, and it is being vigorously promoted at present. Straw carbonization is to dry or sun-dry and crush the straw, and then in the charcoal equipment, through drying, dry distillation, cooling and other processes, the loose straw is The process of making charcoal. During the straw carbonization process, the straw bales are transported to the conveying device through the feeding device, and then sent to the air-drying device through the conveying device. the goal of. The air-dried straw bales need to be pushed i...
