[0002] Soybeans originated in China and are cultivated throughout China, as well as widely around the world. Soybeans are one of China's important food crops, and the screening of soybean seeds is an important task in agricultural production and agricultural product processing.
[0003] Traditional soybean seed screening equipment can only remove fine impurities such as dust and sand. Most devices only have simple sieving functions, and after screening, the remaining soybean hulls still need to be manually picked up or removed by a fan, which is quite cumbersome. Existing soybean seed screening equipment is not very effective at removing light impurities such as soybean hulls, requiring secondary manual processing and consuming a lot of manpower and resources. How to invent a soybean seed screening device to improve these problems has become an urgent problem for those skilled in the art. Utility Model Content

Detailed Implementation
[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a soybean seed screening device, including...
[0031] The equipment housing 100 includes a loading and unloading assembly 110, which includes a support frame 111. A screening bottom shell 112 is elastically mounted on the support frame 111. A cover plate 113 is installed on the upper limit of the screening bottom shell 112. A feed hopper 114 is connected to one side of the top of the cover plate 113. A bean feed hopper 117 and a dust feed hopper 118 are respectively connected to one end of the bottom of the screening bottom shell 112. The screening mechanism 200 includes a vibrating screening assembly 210, which includes a screening plate 213. The screening plate 213 is installed within the loading and unloading assembly 110.
[0032] The auxiliary cleaning mechanism 300 includes a soybean shell cleaning component 310, which is located inside the feeding and unloading component 110 on the upper and lower sides of the screening plate 213. The first blower 311 blows air onto the passing soybean seeds, blowing up the soybean shells. The shells are then guided by the collection plate 313 and assisted by the second blower 314 to accurately blow them out, ensuring the purity of the soybean seeds.
[0033] Please see Figure 3 and Figure 4 The loading and unloading assembly 110 also includes side ears 115, which are symmetrically installed at the four corners on both sides of the screening bottom shell 112. Shock-absorbing springs 116 are fixedly connected to the bottom of each side ear 115, and the bottom of each shock-absorbing spring 116 is fixedly connected to the top four corners of the support frame 111. Hooks 119 are fixedly installed at the four corners on both sides of the screening bottom shell 112 and the cover plate 113. The screening bottom shell 112 and the cover plate 113 are connected by the hooks 119. Releasing the hooks 119 facilitates opening the cover plate 113, and allows for easy replacement of screening plates 213 with different apertures when screening different types of beans.
[0034] The bean feed hopper 117 is connected to the end of the screening bottom shell 112 away from the feed hopper 114. The dust feed hopper 118 is installed inside the bean feed hopper 117 to facilitate the discharge of dust and other impurities first, avoiding simultaneous discharge that would cause remixing of impurities and affect screening efficiency. The vibrating screening assembly 210 also includes a mounting plate 211, which is fixedly installed in the inner bottom of the screening bottom shell 112. A vibrating motor 212 is fixedly installed on the bottom surface of the mounting plate 211.
[0035] Please see Figure 4 and Figure 5 A support plate is fixedly installed on the side of the screening bottom shell 112 located near the bean hopper 117 of the dust hopper 118. A support plate is also provided at the end of the screening bottom shell 112 away from the dust hopper 118. The screening plate 213 is detachably installed on the upper surface of the support plate by bolts. The inner bottom of the screening bottom shell 112 and the screening plate 213 are both inclined. The inclined setting facilitates the movement of the internal material towards the dust hopper 118 and the bean hopper 117 end in coordination with vibration.
[0036] The bean shell cleaning assembly 310 includes a first blower fan 311, which is positioned between the dust hopper 118 and the dust discharge hopper 118. Guide plates 312 are fixedly installed on both sides of the first blower fan 311. A cover plate 113 is located directly above the first blower fan 311 and has a strip-shaped through hole. The first blower fan 311 is installed at the bottom of the screening bottom shell 112. The tops of the guide plates 312 are located at the bottom of the screening plate 213, and the tops of the guide plates 312 are inclined towards the middle of the first blower fan 311. The two guide plates 312 are correspondingly arranged with the strip-shaped through hole of the cover plate 113. The guide plates 312 are used to compress and guide the blown air, causing it to blow out at high speed. The air passes through the beans and blows up the bean shells. A collection plate 313 is fixedly connected to the inner wall of the strip-shaped through hole of the cover plate 113. The collection plate 313 is arranged in a figure-eight shape. A second blower 314 is arranged on the top of the cover plate 113 on one side of the strip-shaped through hole. A protective shell 315 is arranged on the outside of the second blower 314. The figure-eight shape makes it easy to collect the blown bean shells and discharge them upwards. The second blower 314 blows the bean shells out. At the same time, the back of both the second blower 314 and the first blower 311 is hollow to facilitate air intake.
[0037] Working principle:
[0038] Feeding: Soybean seeds enter the equipment through the feed hopper 114 and fall onto the screening plate 213 below the cover plate 113.
[0039] Vibration screening of fine impurities: When the vibration motor 212 is started, it drives the mounting plate 211 and the screening plate 213 to vibrate. During the vibration of soybean seeds on the screening plate 213, fine particles such as dust and sand fall through the screening plate 213 to the bottom of the screening bottom shell 112. With vibration, the fine particles such as dust move towards the dust discharge hopper 118 and are finally discharged from the equipment through the dust discharge hopper 118.
[0040] Soybean hull cleaning: After the initial screening to remove small impurities, the soybean seeds continue to move on the screening plate 213 toward the soybean feed hopper 117. When passing the first blower 311, the first blower 311 blows air onto the soybean seeds, blowing up the soybean hulls. The blown-up soybean hulls move toward the outside of the strip-shaped through hole under the guidance of the collecting plate 313. At the same time, the second blower 314 assists in blowing air to blow the soybean hulls out of the equipment.
[0041] Feeding: After the fine impurities are screened out and the soybean hulls are removed, the pure soybean seeds continue to move to the soybean feeding hopper 117 and are discharged from the equipment through the soybean feeding hopper 117.
[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
