A rocker 42 is fixedly connected to the center of the bottom of the screening box 4, and a compression spring 43 is sleeved on the outside of the rocker 42. A swing motor 421 is embedded at the bottom of the inner cavity of the outer shell 1. The first guide plate 2, the second guide plate 21 and the third guide plate 22 are provided to guide the grains entering the inner cavity of the outer shell 1, and at the same time extend the moving track of the grains in the inner cavity of the outer shell 1. The first guide plate 2, the second guide plate 21 and the third guide plate 22 are arranged alternately;

[0023] In this embodiment, the grains pass through in sequence and enter the inner cavity of the screening box 4. During the sliding process of the grains, the heating plates 3 arranged at the bottom of the first guide plate 2, the second guide plate 21 and the third guide plate 22 heat and dry the grains. By setting the limiting rollers 12, the thickness of the grains passing through the top of the first guide plate 2, the second guide plate 21 and the third guide plate 22 is limited, so that the grains are flatly slid, thereby increasing the efficiency of dehumidification and drying of the grains.

[0024] After the grains are dried, they fall to the center of the screening box 4. The shape of the bottom of the inner cavity of the screening box 4 makes the grains flow to both sides and roll to the two ends of the inner cavity of the screening box 4. The screening box 4 is driven to swing by the rocker 42, the rocking motor 421 and the compression spring 43. The present invention can set a gravity switch between the screening box 4 and the rocker 42. When grains enter the screening box 4, the rocking motor 421 is automatically turned on to screen the grains inside the screening box 4, and the impurities are screened out from the sieves 41 on both sides and the bottom of the screening box 4. The grains remain in the inner cavity of the screening box 4, and the impurities fall to the bottom of the inner cavity of the outer shell 1 and are discharged through the discharge port 14. The grains in the screening box 4 are taken out by opening the sealing cover 15, so that the present invention can make the grains spread in the inner cavity of the outer shell 1 and slide for a longer distance, thereby accelerating the drying and dehumidification efficiency of the grains. After dehumidification, the grains automatically fall into the screening box 4 for screening, and the working efficiency is high.

[0030] Among them, a raised cavity 44 is provided on the center line of the bottom of the screening box 4, and a plurality of rubber pads 45 are fixedly connected on both sides of the screening box 4; by providing the raised cavity 44, the grains entering the screening box 4 can automatically slide to both ends, and by providing the rubber pads 45, the two sides of the screening box 4 are protected to reduce the collision between the screening box 4 and the inner wall of the outer shell 1.

[0031] Embodiment 4

[0032] See also Figure 1 , Figure 2 and Figure 4 This embodiment provides a dehumidification and screening device for grain processing. In addition to the technical solutions of the above-mentioned embodiments one, two, and three, it also has the following technical features: a plurality of electric heating tubes 31 are arranged inside the heating plate 3, and the plurality of electric heating tubes 31 are arranged at equal intervals; by arranging the electric heating tubes 31 at equal intervals, the heating plate 3 can uniformly heat the first material guide plate 2, the second material guide plate 21, and the third material guide plate 22.

[0033] In this embodiment, the first material guide plate 2, the second material guide plate 21 and the third material guide plate 22 are all obliquely arranged in the inner cavity of the outer shell 1, and the first material guide plate 2, the second material guide plate 21 and the third material guide plate 22 are fixedly connected with baffles 23 on both sides; the miscellaneous grains entering the inner cavity of the outer shell 1 are guided, and at the same time, the moving trajectory of the miscellaneous grains in the inner cavity of the outer shell 1 is extended, and the miscellaneous grains are blocked by setting the baffles 23.

[0034] The working principle of the utility model is as follows: by setting the first guide plate 2, the second guide plate 21 and the third guide plate 22, the miscellaneous grains entering the inner cavity of the outer shell 1 are guided, and at the same time, the moving trajectory of the miscellaneous grains in the inner cavity of the outer shell 1 is extended. The first guide plate 2, the second guide plate 21 and the third guide plate 22 are staggered, and the miscellaneous grains pass through in sequence and enter the inner cavity of the screening box 4. In the process of the miscellaneous grains sliding, the heating plate 3 arranged at the bottom of the first guide plate 2, the second guide plate 21 and the third guide plate 22 heats and dries the miscellaneous grains. By setting the limiting roller 12, the miscellaneous grains passing through the top of the first guide plate 2, the second guide plate 21 and the third guide plate 22 are heated and dried. The thickness of the grains is limited so that they can be spread flat and slide, thereby increasing the efficiency of dehumidifying and drying the grains. After drying, the grains fall to the center of the screening box 4. The shape of the bottom of the inner cavity of the screening box 4 causes the grains to be diverted to both sides and roll to the two ends of the inner cavity of the screening box 4. The screening box 4 is driven to swing by the rocker 42, the swing motor 421 and the compression spring 43 to screen the grains inside the screening box 4, and the impurities are screened out from the sieves 41 on both sides and the bottom of the screening box 4. The grains remain in the inner cavity of the screening box 4, and the impurities fall to the bottom of the inner cavity of the outer shell 1 and are discharged through the discharge port 14. The grains in the screening box 4 are taken out by opening the sealing cover 15.
