Straw smashing and throwing device

Abstract

A straw smashing and throwing device comprises a straw smashing and throwing device body. A straw connecting channel is fixedly arranged on the upper end face of the straw smashing and throwing devicebody, a drying layer is fixedly arranged on the periphery of the wall face of an inner cavity of the straw connecting channel, and an air outlet pipe is fixedly arranged on the upper end face of thestraw connecting channel. A smashing chamber is fixedly arranged on the front wall surface of an inner cavity of the straw smashing and throwing device body. According to the straw smashing and throwing device, straw collected during harvesting can be smashed, in the smashing process, the straw is cut up and then ground into powder, and in this way, the straw can be decomposed into nourishment byland as soon as possible; and in the discharging process, a throwing device is used for throwing out the powder to enable the powder to be evenly thrown into the land, water is sprayed to the powder to prevent the powder from drifting around in the throwing process, after the powder is thrown out, the powder is buried in the soil through a later ploughing device, the straw powder returning to theland is better rotted, and efficient organic fertilizer is provided for subsequent crops.

Description

technical field [0001] The invention relates to a straw crushing and spreading device, and mainly relates to the field of harvesters. Background technique [0002] When the current harvester harvests grain, the stalks are initially crushed and then discharged from the straw outlet of the harvester. As the harvester advances, the stalks are piled up in rows in the field, and then these stalks will be collected for the second time. Manpower and material resources make it impossible to return the straw to the field to provide organic fertilizer for the next crop. In addition, even if the straw in the field is not collected twice, but the field is plowed directly with a large tractor, the straw will be large in size and piled up. It is not easy to rot, and it will cause adverse effects on the growth of the next crop. Aiming at the above shortcomings, the present invention improves. Contents of the invention [0003] The technical problem to be solved by the present invention ...
