Crop residual stem post-treatment and impurity removal process and equipment

Abstract

The invention discloses a crop residual stem post-treatment and impurity removal process and equipment. The process comprises the following steps that crop residual stems are chopped to obtain residual stems crushed materials; screening treatment is conducted on the residual stems crushed materials to screen out residual stem crushed materials with the crushing degree meeting the requirement, and meanwhile, impurity removal treatment is conducted on the residual stems crushed materials; and the residual stem crushed materials with the crushing degree meeting the requirement are collected. The equipment comprises a chopping part, a screening and impurity removing part and a collecting part, wherein the chopping part, the screening and impurity removing part and the collecting part are used for chopping the crop residual stems, screening the residual stem crushed materials, removing impurities from the residual stem crushed materials and collecting the residual stem crushed materials with the crushing degree meeting the requirement. According to the crop residual stem post-treatment and impurity removal process and equipment, impurities originally mixed in the crop residual stems can be effectively removed, the impurity removal effect is good, the situation that feed obtained through the crop residual stems finally contains harmful substances can be prevented, and the residual stem crushed materials obtained after chopping and screening treatment are beneficial to subsequent continuous processing.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a post-processing and impurity removal process and equipment for crop residues. Background technique [0002] In agriculture, after harvesting agricultural products, there will be a lot of stumps of agricultural products left. These stubs of agricultural products need to be post-processed to play their value, and also solve the problem of nowhere to place the stubs of agricultural products. At present, the treatment of crop stubs is mainly based on returning to the field. After returning to the field, the stubs of crops act as fertilizers and can use the growth of the next crop. For crop stubs with feed value, if they are simply returned to the field, it is not conducive to exerting their residual value. If they can be processed into feed and sold, the planting income can be further improved. In the process of processing crop residues, there is an unavoidable prob...
