Agricultural straw shredding device

Abstract

The invention discloses an agricultural straw shredding device in the field of agricultural machinery. The device comprises a supporting bottom plate; the two sides of the top of the supporting bottomplate are fixedly connected with supporting side columns; the tops of the supporting side columnsare fixedly connected witha supporting top plate; the middle of the supporting top plate is provided with a crushing bin in a penetration manner; the tops of the two side walls of the crushing bin fixedly communicate with feeding mechanisms; the top of the crushing bin is fixedly connected with a drying mechanism; the lower end of the drying mechanism is arranged on the upper side wall of the crushing bin in a penetration manner; the lower end of the drying mechanism communicates with a filteringbaffle; the filtering baffle is arranged at the upper part of an inner cavity of the crushing bin; and the lower part of the filtering baffle is provided with a fixed ring mechanism. The fixed ring mechanism is arranged, and a driving shaft is arranged between the fixed ring mechanism and the middle of the lower side wall of the crushing bin, so that straws can be effectively isolated from entering a hot air blower while the driving shaft is supported to rotate, the hot air blower is prevented from being damaged, and popularization of the device is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an agricultural straw chopping device. Background technique [0002] my country is a large agricultural country with abundant crop straw resources. As a good clean and renewable resource, straw has good economic, ecological and social benefits, and has been paid more and more attention to and utilized by people, such as biomass power generation. However, the density of crop straw is small and it is inconvenient to transport and store. Therefore, storing and transporting straw into bundles is the key to reducing the cost of raw material collection and storage and promoting the industrial utilization of straw. The return of straw to the field can avoid problems such as the failure of vehicles to run normally, the failure of aircraft to take off and land, serious environmental pollution, and destruction of organic matter in the soil due to the smoke from burning straw. Straw ...

Problems solved by technology

[0005] The purpose of the present invention is to provide an agricultural straw chopping device to solve the problem that the feeding system of the existing baler proposed in the above background technology can only feed short straws into bales, and long straws will be entangled in the feeding system. On the rotating shaft of the feeding system, it will cause the feeding system to be blocked and reduce the working efficiency of the baler, which will lead to the problems of long working time, high labor intensity and low efficiency.
