Problems solved by technology

[0002] Although Xinjiang and other northwest regions have a relatively large area, the area of ​​cultivated land is relatively small, and the interplanting mode of grains and fruit trees is relatively common, which determines that harvesting and threshing operations should be carried out separately; , so there have been various grain threshers, but there are the following deficiencies: In the process of grain winnowing and screening, if the wind is strong, the grain is easily blown out of the machine, resulting in waste; if the wind is weak, the winnowing efficiency will be reduced, and it is difficult for orange stem powder to be blown out of the machine; After passing through the single-layer vibrating sieve, the crushed grains and orange stalks are not easy to disperse and have a relatively small contact area with wind force, which affects the winnowing effect; Part of the equipment is designed with a secondary cleaning device, but after cleaning, the crushed orange stems are blown out from the other side, and the area of ​​sand and dust pollution is relatively large, which affects the health of the operators; The form of power configuration is single, the design of the reserve power source is unreasonable, and it is not easy to operate; for these reasons, the main assessment indicators of the thresher, such as the total loss rate, broken rate, impurity rate, and clean rate, cannot meet the standards, resulting in poor grain quality and poor applicability And other issues

Embodiment Construction

[0014] Such as figure 1 , 2 As shown, the present invention comprises frame 10, feeding mechanism 1, crushing and threshing mechanism 2, winnowing device 11, shaking screen mechanism 3, main blower 4, auxiliary blower 8, electric power source mechanism 9, transport mechanism 5, two Secondary cleaning device 6, return mechanism 7, transmission mechanism, feeding mechanism 1 and crushing and threshing mechanism 2 are installed on the frame 10 respectively, and feeding mechanism 1 feeds wheat draft to crushing and threshing mechanism 2; A winnowing device 11 is provided, and a vibrating sieve mechanism 3 is arranged in the winnowing device 11, and the wheat manuscript crushed by the crushing and threshing mechanism 2 falls on the shaking sieve mechanism 3, and is screened and cleaned through two layers of sieves to strengthen the screening effect; The main blower 4 is arranged at the position below the feeding mechanism 1 behind the frame 10, and provides wind power to the shaki...

Abstract

The invention relates to a selected grain thresher. The main assessment indicators of the existing threshers are the total loss rate, crushing rate, impurity content rate, and cleaning rate, etc., which cannot meet the standards, resulting in poor grain quality and poor applicability. The invention includes a frame and a feeding mechanism arranged on the frame, a crushing and threshing mechanism, a winnowing device, a secondary cleaning device, a power source mechanism, and a transmission mechanism. The feeding mechanism is arranged at the front part of the crushing and threshing mechanism. The lower part of the crushing and threshing mechanism is equipped with a wind separation device, and one side of the frame is equipped with a secondary cleaning device, and the wind separation device communicates with the secondary cleaning device through a transport mechanism. The invention avoids the grain being blown out of the machine, overcomes the shortage that orange stalk powder is difficult to be blown out of the machine, improves the screening efficiency, realizes that the crushed orange stalk is blown out by one outlet, reduces the area polluted by sand and dust, and adapts to various Energy, use electricity with electricity, use tractor energy without electricity, so that customers have one more choice.

Description

technical field [0001] The invention relates to the technical field of grain threshing and cleaning in the field of agricultural machinery, in particular to a sorting grain thresher. Background technique [0002] Although Xinjiang and other northwest regions have a relatively large area, the area of ​​cultivated land is relatively small, and the interplanting mode of grains and fruit trees is relatively common, which determines that harvesting and threshing operations should be carried out separately; , so there have been various grain threshers, but there are the following deficiencies: In the process of grain winnowing and screening, if the wind is strong, the grain is easily blown out of the machine, resulting in waste; if the wind is weak, the winnowing efficiency will be reduced, and it is difficult for orange stem powder to be blown out of the machine; After passing through the single-layer vibrating sieve, the crushed grains and orange stalks are not easy to disper...
