Embodiment Construction

[0021] See Figure 1 to Figure 3 The reverse separation and grain cleaning device of the rice-wheat combine harvester includes a sieve 1 installed on a frame and capable of reciprocating swing driven by a driving mechanism, and an exhaust fan 2 is installed above the sieve 1.

[0022] The sieve bodies can be composed of a sieve bottom and ribs 4 on both sides corresponding to each other.

[0023] The exhaust fan 2 can be installed above the middle of the screen.

[0024] It can also be at the rear end of the sieve 1 (i.e. Figure 1 to Figure 3 The right end of the middle) is provided with a straw trough 3.

[0025] During actual installation, such as image 3 As shown, the sieve 1 is suspended on the frame 5, one end of the connecting rod 6 is hinged on the eccentric shaft of the sprocket 7, and the other end is hinged to one side of the sieve 1 to form the driving mechanism of the sieve 1; when the sprocket 7 When rotating, the screen 1 is driven to reciprocate (jitter) accordingly.

Abstract

The invention discloses a reversed separation grain cleaning device of a rice and wheat combine, which comprises a sieve 1 arranged on a stand and driven by a driving mechanism to reciprocate, and is characterized in that an exhaust fan 2 is arranged above the sieve 1. The reversed separation grain cleaning device has the characteristics of good grain cleaning effect for grain and grass separation, simple structure, small volume, light weight, less power consumption and the like.

Description

Technical field [0001] The invention relates to agricultural machinery, and further refers to a grain cleaning device for separating grain and grass installed on a rice-wheat combine harvester. Background technique [0002] At present, the grain cleaning devices on the rice-wheat combine harvester that separate weeds and grains are all air-flow screen-type grain cleaning devices composed of multi-layer screens and fans. The screens used include woven screens or fish-eye screens, perforated screens, and fish-scale screens. The bottom of these sieves is flat and evenly densely covered with sieve holes for the grains to pass through; one end of the sieve is equipped with a fan, which has centrifugal or axial fans, and the generated air flows through the entire sieve surface from inside to outside. The grains and grains move outwards. In order to completely separate the grains and weeds, the general grain cleaning device has two-layer sieves with different sieves, and there is a seco...
