Embodiment Construction

[0019] See figure 1 versus figure 2 , Said a kind of suction and blast combined separation type grain cleaning device of the harvester, including a screen 1 installed on the frame and reciprocating swing driven by a driving mechanism. The screen 1 consists of a single-layer sieve body 2 and a sieving grain bin 3, the single-layer sieve body 2 includes a sieve bottom plate 4 and a box baffle 6. The front section of the box baffle 6 is equipped with a sieve bottom plate 4, and the rear section is an inlet 8, such as image 3 with Figure 4 As shown, the sieve 1 is suspended on the frame 11, one end of the connecting rod 12 is hinged to the eccentric sprocket 7, and the other end is hinged to the swing lever 15 on the side of the sieve 1. When the eccentric sprocket 7 rotates, the sieve is driven 1 is reciprocating (jittering), the top of the screen 1 is equipped with an exhaust fan 10 and a wind collecting hood 14, and one end of the screen 1 is equipped with a blower 13.

Abstract

The invention relates to an air suction and air blow-combined separation type grain cleaning device for a reaping machine. The device comprises a sieve which is arranged on a machine frame and is driven by a driving mechanism to swing back and forth, wherein the sieve consists of a single-layered sieve body and a grain warehouse attached to the sieve; the single-layered sieve body comprises a sieve bottom board and a square frame baffle; the front section of the square frame baffle is provided with the sieve bottom board, and the rear section of the square frame baffle is provided with a warehouse inlet; a draft fan and an air collection hood are arranged above the sieve; and one end of the sieve is provided with an air blower. The device can separate grains and weeds efficiently, the separated grains contain a small number of impurities, and the device has the advantages of simple structure, small volume, low power consumption and the like.

Description

Technical field [0001] The present invention relates to agricultural machinery, and further refers to a separation type grain cleaning device combined with a suction blast of a harvester. Background technique [0002] At present, the grain cleaning devices that separate weeds and grains on combine harvesters are mostly winnowing and sieve combination structure, winnowing usually adopts blasting method, the sieves used include woven screen or fish eye screen, punching screen, fish scale screen, blower Installed at one end of the sieve, the air flow generated from the inside to the outside flows through the entire sieve surface, weeds and grains are separated during the outward movement, and some use the air extraction method, but these two air separation devices have The effect is not good, and the impurity content is high. In order to completely separate the grains and weeds, multi-layer sieves are usually used and a secondary cleaning structure is installed. The mechanism is com...
