Single wheat/rice plant threshing device

Abstract

The invention relates to a single wheat / rice plant threshing device comprising a centrifugal fan type thresher, a separating container and a mounting base. The centrifugal fan type thresher comprises a power mechanism, impellers, a volute casing and a wheat / rice ear inlet bucket. The impellers are arranged in the volute casing in a matching way and is connected with the rotating shaft of the power mechanism; the volute casing is provided with an air inlet and an air outlet, wherein the air inlet is butted with the wheat / rice ear inlet bucket, and the air outlet is communicated with the middle part of the separating container; the included angle Alpha between the air outlet direction and the horizontal direction is more than or equal to -30 DEG and less than or equal to 30 DEG; a wheat / rice bran discharge opening is arranged on the top of the separating container; and a movable wheat / rice kernel collecting slot which is matched with the separating container in shape is arranged at the bottom of the separating container. The single wheat / rice plant threshing device has novel and compact structure, small volume, light weight, low manufacturing cost, high threshing ratio, high intactness keeping ratio, high cleaning ratio, low breaking ratio, low retaining and adulterating ratio and low splashing ratio, has no dead corner for the residual and less wheat / rice kernel flow and collision link, is easy to use, consumes less power and can ensure the high purity and the high quality of the wheat / rice kernels and the material.

Description

technical field [0001] The invention relates to a grain threshing device, in particular to a wheat / rice single plant threshing device. Background technique [0002] Wheat and rice are important food crops in my country. Rapidly cultivating new varieties of wheat and rice with high yield, high quality and strong stress resistance has always been the goal pursued by breeders. Both wheat and rice are monocotyledonous self-pollinating crops, and generally can produce multiple tillers, that is, they have branching characteristics. In the work of cross breeding, the method of individual selection is often used to quickly purify the target gene and prevent the genetic mixing of important lines. Therefore, in the process of hybrid offspring selection and improved breeding, it is necessary to thresh a large number of selected excellent individual plants, and in the genetic analysis, gene mapping and functional gene cloning of wheat and rice crops, it is inseparable from a large numb...

Problems solved by technology

However, the above-mentioned known single plant (ear) threshers generally have a complex design structure, many corners and gaps, which are easy to cause inconvenience in cleaning and mixed grains. (such as breeding units below the county level and farmer breeders) promotion and application

In addition, this type of machine is heavy and inconvenient to move is also a more prominent problem
