Problems solved by technology

The traditional field breeding threshing is done manually or semi-mechanized. The harvest period is long, the farming time is delayed, the indirect loss is large, the internal cleaning of the thresher is difficult, and the residual amount of grain is large, which may easily cause the grain to be mixed and cause the experimental data to be distorted.

Embodiment Construction

[0044] see Figure 1-Figure 5 , The rape field breeding thresher of the present invention includes a threshing system, a cleaning system and a transmission system installed on the frame D.

[0045]The threshing system includes a threshing chamber A formed by a drum cover 11, a drum shaft 15 installed on the frame D through the drum bearing seat 16 runs through the threshing chamber A, and one end of the drum shaft 15 is provided with a spiral Feed the auger 10 in a shape distribution. A feeding port 25 is arranged on the drum cover 11 corresponding to the feeding auger 10. The feeding port 25 is preferably arranged in the tangential direction of the feeding auger 10, and the protruding part of the feeding port 25 is in an inverted V shape. A shield (not shown) may be provided on the top of the feeding port 25 . Like this, the oilseed rape that is sent into through feeding inlet 25 just can fall into feeding auger 10 places smoothly. The drum shaft 15 located at the output e...

Abstract

A breeding seed threshing machine used in oilseed rape fields comprises a threshing system, a screening system and a transmission system which are mounted on a frame. The threshing system comprises a threshing chamber, a roller shaft penetrates through the threshing chamber, a feeding auger, a threshing roller and a grass removing plate are sequentially arranged on the roller shaft, a feeding inlet is arranged on the feeding auger, the grass removing plate is provided with a straw outlet, threshing spike teeth which are spirally distributed are arranged on the threshing roller, and a concave screen is arranged below the threshing roller. The screening system comprises a vibrating screen arranged below the concave screen, a seed discharging port is formed below the vibrating screen, a fan air inlet is formed on the frame on one side of the seed discharging port, a screening fan is mounted on the fan air inlet, and a bran outlet is arranged at the position, corresponding to the fan air inlet, of the frame. The transmission system provides power to the roller shaft, the screening fan and the vibrating screen. The breeding seed threshing machine has the advantages that almost no seeds are left in the threshing machine, a good screening effect and short screening time are achieved and an oil seed breakage rate is low.

Description

technical field [0001] The invention relates to a thresher, in particular to a rapeseed field breeding thresher. Background technique [0002] Rapeseed is the main oilseed crop in my country. To vigorously develop the rapeseed industry, we must not only expand the planting area and increase the total output of rapeseed, but also need to breed better new varieties of rapeseed. Field breeding is an effective means of breeding new varieties and breeding improved varieties, and is an important link in crop production. Traditional field breeding threshing is done manually or semi-mechanized. The harvest period is long, the farming time is delayed, the indirect loss is large, the internal cleaning of the thresher is difficult, the residual amount of grain is large, and the grain is easily mixed, resulting in distortion of test data. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to develop a field breeding threshe...
