Problems solved by technology

For the existing axial-flow threshing separation device, the threshing device is generally set in a straight line. When threshing, the crops are fed from the feeding port of the threshing drum, and the threshing is carried out as the threshing drum rotates. Clean, low cleaning rate and high grain breakage rate
At the same time, the detached stalks are relatively broken, and the content of impurities in the detached mixture is high, which increases the subsequent cleaning load and reduces the quality of threshing operations. Therefore, there is a situation of high labor intensity and low work efficiency.

Embodiment Construction

[0021] Such as figure 1 , figure 2 and image 3 As shown, a double-drum threshing machine of the present invention includes a power unit, a body, a primary threshing device, and a secondary threshing device. The secondary threshing device is composed of a secondary threshing drum 6, a secondary threshing sieve plate 5 and a body, the first threshing chamber is formed between the primary threshing drum 12, the primary threshing sieve plate 13 and the body, and the two A second threshing chamber is formed between the secondary threshing drum 6 , the secondary threshing sieve plate 5 and the body, and the first threshing chamber communicates with the second threshing chamber. This double-drum structure creatively solves the technical problem of only one threshing, and the threshing is not clean. After the rice is threshed by a threshing device, the removed rice grains fall into the barn 3 along the primary threshing sieve plate 13, and the threshing is not clean. The ears of ...

Abstract

The invention relates to a double-drum threshing machine. The double-drum threshing machine comprises a power device, a machine body, a primary threshing device and a secondary threshing device, wherein the primary threshing device is composed of a primary threshing drum, a primary threshing sieve plate and the machine body, the secondary threshing device is composed of a secondary threshing drum, a secondary threshing sieve plate and the machine body, the primary threshing drum, the primary threshing sieve plate and the machine body form a first threshing cavity, the secondary threshing drum, the secondary threshing sieve plate and the machine body form a secondary threshing cavity, and the first threshing cavity is communicated with the second threshing cavity. The double-drum threshing machine provided by the invention has the advantages of simple structure, high threshing rate, low grain impurity rate, easy operation and wide application range.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery engineering, in particular to a double-drum thresher. Background technique [0002] Rice is one of the main food crops in my country and the main source of income for farmers. However, many rice fields in our country belong to hilly areas with small plots, and it takes a lot of time for farmers to harvest. As a widely used small-scale agricultural machinery, rice threshers are machines that can separate crop grains from stalks. [0003] Existing threshers are usually only provided with a threshing cylinder, and the threshing cylinder can carry out threshing operation when the threshing cylinder rotates under the drive of the motor, so that the grains that come out are mixed with the broken rod leaves, and the grains will be separated by a fan after harvesting. For the existing axial-flow threshing separation device, the threshing device is generally set in a straight line. When thr...
