TECHNICAL FIELD
[0001] The utility model relates to the technical field of screening, in particular to a screening device for agricultural and sideline products. BACKGROUND
[0002] Agricultural and sideline products are by-products of agricultural production, including products of five industries, namely, farming, forestry, animal husbandry, sideline production and fishery, which are divided into several categories, such as grain, economic crops, bamboo and wood, industrial oil and paint glue, poultry products, cocoon and silk, dried and fresh fruits, dried and fresh vegetables and condiments, medicinal materials, soil sideline products and aquatic products. Each category is further divided into several sub-categories. During the production process of agricultural and sideline products, it is necessary to screen the products. For example, after the hulling of bean products, a large amount of impurities such as skins and shells may be mixed in the products, which need to be screened and removed to improve the purity of the products.
[0003] However, the screen size of the screening device is fixed, which is not convenient for screening other agricultural and sideline products. The screen of some screening devices can be replaced, but the replacement is time-consuming and laborious, and the user experience needs to be improved. Therefore, we propose a screening device for agricultural and sideline products. SUMMARY

DETAILED DESCRIPTION
[0028] Please refer to Figs. 1-3 The application provides a technical scheme: an agricultural and sideline product screening device, which comprises a screen box 1 and a screen cylinder 2. The bottom of the screen box 1 is vertically supported and fixed with supporting legs 14. The supporting legs 14 are provided with a plurality of supporting legs 14, which support the screen box 1.
[0029] A rotating rod 21 is vertically arranged in the middle of the screen cylinder 2. The rotating rod 21 is fixed in the screen cylinder 2 by a plurality of connecting rods 211, so that the screen cylinder 2 can be obliquely and rotatably arranged in the screen box 1 through the rotating rod 21. The rotating rod 21 is in transmission connection with a stepping motor 12 arranged at the end of the screen box 1. When the rotating angle of the rotating rod 21 is controlled by the stepping motor 12, the screen cylinder 2 can be accurately rotated by a specified angle.
[0030] Four equal-sized screening zones 22 are arranged around the outer ring of the screening cylinder 2, and the mesh hole diameters of each screening zone 22 are sequentially increased, so that during use, the appropriate screening zone 22 can be selected according to the size of the agricultural and sideline products to be screened, and the screening zone 22 is rotated to the position directly below by driving the screening cylinder 2 to rotate by the stepping motor 12. An observation window 16 is arranged at the front end of the screening box 1, and the observation window 16 is located on the surface of the screening box 1 at the front end of the position of the screening cylinder 2, so that when adjusting the screening zone 22, the observation window 16 can be used to observe whether the screening zone 22 adjusted to the below position is correct.
[0031] A feed hopper 11 is arranged on the surface side of the screening box 1, and a lower discharge pipe 111 is connected below the feed hopper 11 and extends into the inside of the screening box 1 and the inside of the screening cylinder 2. The lower end of the lower discharge pipe 111 is arranged in a staggered manner with the rotating rod 21, and the lower discharge pipe 111 is close to the middle position. The agricultural and sideline products are added from the feed hopper 11, and due to the staggered arrangement, the agricultural and sideline products are prevented from falling to the lowest screening zone 22 in a hitting state, so that the agricultural and sideline products are screened.
[0032] A baffle 23 is also fixed inside the screening cylinder 2 at the junction of the screening zones 22. The baffle 23 is fixed to the inner surface of the screening cylinder 2 by welding. During screening, the baffle 23 can prevent the agricultural and sideline products from rolling to other screening zones 22 when the lowest screening zone 22 is used.
[0033] A discharge port 13 and a discharge pipe 15 are arranged on the side surface of the screening box 1 and the bottom of the screening box 1 at the low end of the screening cylinder 2, and the discharge port 13 is in communication with the screening box 1. An inclined guide plate 132 is fixed inside the screening box 1 below the discharge port 13, one side of the guide plate 132 is below the screening cylinder 2, and a guide groove 131 is welded and fixed outside the screening box 1 below the discharge port 13. Therefore, the fine materials after screening can be directly discharged from the discharge pipe 15, and the coarse materials can be guided by the guide plate 132, discharged from the discharge port 13, and guided by the guide groove 131.
[0034] During use, the stepping motor 12 is connected to an industrial computer and a power supply. Before screening, the appropriate screening zone 22 is selected according to the agricultural and sideline products to be screened, the rotating rod 21 and the screening cylinder 2 are driven to rotate by the stepping motor 12, the screening zone 22 to be used is rotated to the position directly below and locked, and then the agricultural and sideline products to be screened are put into the feed hopper 11. Under the guiding action of the lower discharge pipe 111, the agricultural and sideline products fall to the lowest screening zone 22. The agricultural and sideline products roll downward under the action of gravity and are screened, and the large-particle products are discharged from the left side, guided by the guide plate 132, discharged from the discharge port 13, and guided by the guide groove 131. The small-particle impurities are discharged from the discharge pipe 15 below the lowest screening zone 22 after passing through the screening zone 22. When subsequent screening of other agricultural and sideline products is required, the screening zone 22 to be used can also be rotated to the position directly below by driving the screening cylinder 2 to rotate by the stepping motor 12 before screening.
