Description

Technical Field

[0001] This utility model belongs to the field of soybean processing technology, and specifically relates to a soybean grading and screening machine. Background Technology

[0002] Soybeans, also known as soybeans, are annual herbaceous plants and one of the most important legume varieties in the world. They are widely used in the brewing industry as a raw material for the preparation of various condiments such as soy sauce and sauces. Yellow soybeans are the most widely planted variety of soybeans and are most commonly used to make various soy products, brew soy sauce, and extract protein. Soybean residue or coarse powder is also often used as poultry and livestock feed. When using soybeans for various soy products, extracting soybean oil, brewing soy sauce, and extracting protein, it is necessary to select high-quality soybeans with plump grains and no breakage. Therefore, soybeans must be screened before washing and grinding.

[0003] Existing soybean grading and screening devices, while meeting the basic requirements for grading and screening soybeans, typically discharge the soybeans through a discharge port located at the side of the sorting structure after grading and screening. Since the discharge port only corresponds to a portion of the sorting structure, when the amount of soybeans remaining in the sorting structure is small, the remaining soybeans cannot be automatically transferred towards the discharge port. This prevents users from continuing to discharge soybeans through the discharge port, requiring users to take additional measures to assist in discharging the remaining soybeans in the sorting structure. This is quite troublesome and also affects the overall efficiency of soybean grading and screening.

[0004] For example, patent application CN111715518A discloses a soybean grading and screening device. In this patent application, the right wall of the screening box has three identical openings from top to bottom, and each opening has a discharge port connected to its right side. When the soybeans are graded and screened and fall onto the three screening plates, they can only be discharged through the openings and discharge ports on the right side of the screening plates. Since the openings and discharge ports only correspond to a localized area on the right side of the screening box, when the amount of soybeans remaining on the screening plates is small, the device cannot automatically move soybeans far from the openings to the openings. Instead, the user needs to take other measures to assist in discharging the soybeans, which causes inconvenience and affects the efficiency of soybean screening. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the existing technology by providing a soybean grading and screening machine. It not only meets the basic requirements for grading and screening soybeans, but also automatically moves soybeans that are far from the discharge port to a position closer to the discharge port, thereby automatically and thoroughly discharging the sorted soybeans and better meeting the needs of grading and screening soybeans.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A soybean grading and screening machine includes a base with multiple springs vertically arranged on it. A base seat is mounted on each of the springs. First support legs are hinged to the front and rear sides of the right end of the base. A screening box is mounted on the top of the two first support legs. A feed hopper is located on the top of the screening box. Multiple screens are arranged sequentially from top to bottom within the screening box, with the mesh size decreasing from top to bottom. Discharge pipes, each adapted to one of the multiple screens, are located on the right end of the screening box, with the length decreasing from top to bottom. Control valves are mounted on each of the discharge pipes. Second support legs are located on the front and rear sides of the left end of the screening box. The box is also equipped with multiple vibration motors, and the base is equipped with a drive module for rotating the screening box. The top right end of the screening box is also equipped with a fixing groove with an opening facing downward and extending to the outer sides of the front and rear ends of the screening box. A bidirectional screw is rotatably installed in the fixing groove, and a drive motor for rotating the bidirectional screw is installed on the fixing groove. The two ends of the bidirectional screw are respectively screwed with fixing blocks that are slidably connected to the fixing groove. The bottom of the two fixing blocks is respectively equipped with vertical plates, and the two vertical plates are respectively equipped with horizontal bars located above multiple screens and slidably connected to the screening box. The inner ends of the multiple horizontal bars are respectively equipped with push plates adapted to the screens.

[0008] As a further improvement of this utility model, the drive module includes a U-shaped limiting groove located at the left end of the base and adapted to the two second support legs respectively. A rotation clearance is provided between the bottom of the limiting groove and the second support legs. A fixing plate is also provided at the left end of the base. A telescopic push rod is horizontally arranged on the fixing plate along the left-right direction. A support block with a trapezoidal longitudinal section is slidably mounted on the output shaft of the telescopic push rod and is mounted on the base. A pad adapted to the support block is provided at the bottom left end of the screening box. The bottom of the pad is arc-shaped. The user can easily adjust the screening box to a rightward tilt by adjusting the support block to the right using the telescopic push rod. The support module can be released by adjusting the support block to the left using the telescopic push rod, allowing the screening box to return to a horizontal state. By rotating the clearance, interference between the second support legs and the base can be avoided during the tilting and horizontal adjustment of the screening box.

[0009] As a further improvement of this utility model, a T-shaped mounting bracket is also provided at the right end of the support block. The front and rear ends of the mounting bracket are respectively provided with a limiting rod that can pass through the limiting groove and be inserted into the second support leg. The limiting groove is provided with a first insertion hole that matches the limiting rod, and the second support leg is provided with a second insertion hole that matches the limiting rod.

[0010] As a further improvement of this utility model, the side of the screening box is also provided with multiple mounting frames, and transparent observation windows are provided in the mounting frames.

[0011] As a further improvement of this utility model, the mounting frame is snapped and fixed to the side end of the screening box. The side end of the mounting frame is also provided with a connecting plate, and the connecting plate is also provided with connecting bolts for screwing and fixing to the screening box. The screening box is provided with threaded connection holes that are compatible with the connecting bolts.

[0012] As a further improvement of this utility model, an extension plate is provided on the side of the base, and anchor bolts for connecting to the ground are provided on the extension plate. The extension plate and anchor bolts can effectively prevent the device from easily shifting during operation, making it easier for users to grade and screen soybeans.

[0013] As a further improvement of this utility model, the base is also provided with multiple guide tubes, and the bottom of the base is provided with guide rods that are plugged into and connected to the guide tubes.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] Firstly, by employing a technology that tilts the soybean screening box to the right, allowing for initial discharge through the discharge pipe, and then using a combination of a fixed groove, a bidirectional screw, a drive motor, two fixed blocks, two vertical plates, horizontal bars on both sides, and pusher plates on both sides to push the soybeans located at the front and rear ends of the right side of the screening box and far from the discharge pipe to the discharge cylinder, the technology effectively solves the technical problem in existing technologies where soybeans far from the discharge structure cannot be automatically transferred to a position closer to the discharge structure, resulting in low discharge efficiency. This solution achieves rapid and thorough discharge of sorted soybeans and improves the overall efficiency of soybean screening.

[0016] Secondly, by employing a technical solution that uses a mounting bracket, a limiting rod, a first insertion hole, and a second insertion hole to automatically release the limiting aid of the screening box to be tilted and to automatically limit the screening box to be restored to a vertical position, the technical problems in the prior art, such as the inability to automatically release the screening box to be tilted and the inability to automatically fix the screening box to be restored to a horizontal position, are effectively solved. This achieves the technical effect of automatically and conveniently realizing or releasing the limiting aid of the screening box, thereby further improving the efficiency of soybean screening.

[0017] Thirdly, by adopting a technical solution that includes an installation frame and a transparent observation window on the side of the sorting box, the technical problem of not being able to easily view the inside of the sorting box during the sorting process of soybeans is effectively solved. This results in the technical effect that allows users to easily obtain information such as the sorting progress of soybeans, making it easier for users to arrange subsequent sorting work.

[0018] Fourth, by using a guide tube and guide rod that are interlocked to guide the vibration process of the base relative to the base, the technical solution effectively solves the technical problem in the existing technology that simply connects the base and the base with multiple springs, allowing the base to vibrate relative to the base, which easily causes the base to shift non-vertically relative to the base and makes the springs easily damaged. Thus, it achieves the ability for the base and the screening box to vibrate vertically smoothly to sort soybeans, and effectively avoids the easy deformation and damage of multiple springs.

[0032] Example:

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a soybean grading and screening machine includes a base 101, on which multiple springs 102 are vertically arranged. A base 103 is mounted on the multiple springs 102. First support legs 104 are hinged to the front and rear sides of the right end of the base 103. A screening box 105 is mounted on the top of the two first support legs 104. A feed hopper 106 is mounted on the top of the screening box 105. Multiple screens 107 are arranged sequentially from top to bottom in the screening box 105, with the mesh size decreasing from top to bottom. A discharge pipe 108, adapted to the multiple screens 107, is located on the right end of the screening box 105. The length of the multiple discharge pipes 108 decreases from top to bottom. Control valves 109 are mounted on each of the multiple discharge pipes 108. Second support legs 110 are mounted on the front and rear sides of the left end of the screening box 105. Multiple vibration motors 111 are also provided on the 05, and a drive module for driving the screening box 105 to rotate is also provided on the base 103. A fixing groove 112 with an opening facing downward and extending to the outer sides of the front and rear ends of the screening box 105 is also provided on the top right end of the screening box 105. A bidirectional screw 113 is rotatably provided in the fixing groove 112. A drive motor 114 for driving the bidirectional screw 113 to rotate is provided on the fixing groove 112. Fixing blocks 115 that are slidably connected to the fixing groove 112 are screwed to both ends of the bidirectional screw 113. Vertical plates 116 are provided at the bottom of the two fixing blocks 115. Horizontal bars 117 located above multiple screens 107 and slidably connected to the screening box 105 are provided on the two vertical plates 116. Push plates 118 that are adapted to the screens 107 are provided on the inner ends of the multiple horizontal bars 117.

[0034] like Figure 1 and Figure 5 As shown, the drive module includes a U-shaped limiting groove 201 located at the left end of the base 103 and adapted to the two second support legs 110 respectively. A rotation clearance 202 is left between the bottom of the limiting groove 201 and the second support leg 110. A fixing plate 203 is also provided at the left end of the base 103. A telescopic push rod 204 is arranged laterally along the left and right directions on the fixing plate 203. A support block 205 with a trapezoidal longitudinal section is provided on the output shaft of the telescopic push rod 204 and is slidably arranged with the base 103. A pad block 206 adapted to the support block 205 is provided at the bottom left end of the screening box 105. The bottom of the pad block 206 is arc-shaped.

[0035] Users can add soybeans to be graded and screened into the screening box 105 through the feed hopper 106. Then, the vibration motor 111 can be started. With the cooperation of multiple springs 102, the base 103, the first support leg 104, the second support leg 110 and the screening box 105 will vibrate vertically in sync, thereby vibrating the soybeans. The soybeans will pass through the sieve holes of the corresponding screen 107 from top to bottom according to their particle size and be retained on the next level of screen 107. The smallest soybeans will be retained on the bottom screen 107. Then, the vibration motor 111 can be stopped.

[0036] Then, the output shaft of the telescopic push rod 204 can be extended by a certain length, causing the support block 205 to move to the right. By supporting different parts of the pad block 206, the first support leg 104 rotates relative to the base 103, causing the screening box 105 to tilt to the right at a certain angle. At this time, the control valve 109 can be opened, and soybeans of the corresponding size can be discharged through multiple discharge pipes 108 of different lengths. When most of the soybeans on each layer of screen 107 have been discharged, and only the soybeans in the rightmost area far from the discharge pipe 108 cannot be discharged smoothly, the drive motor can be started, causing the push plates 118 on both sides to move towards the discharge pipe 108, pushing the retained soybeans to the position corresponding to the discharge pipe 108, thereby quickly and thoroughly transferring the soybeans retained in the screening box 105 and on multiple screens 107, thus automatically and thoroughly discharging the screened soybeans. Then the drive motor 114 can be rotated in the opposite direction, causing the two fixed blocks 115 and the pusher plates 118 on both sides to move away from the discharge pipe 108 and reset.

[0037] Then the output shaft of the telescopic push rod 204 can be shortened by a certain length, so that the support block 205 can be moved to the left to reset, gradually releasing the support of the pad block 206, so that the screening box 105 can be restored to a horizontal state, and the second support leg 110 can be pressed against the base 103 again.

[0038] According to another embodiment of the present invention, such as Figure 3 and Figure 5 As shown, a T-shaped mounting bracket 207 is also provided at the right end of the support block 205. The front and rear ends of the mounting bracket 207 are respectively provided with a limiting rod 208 that can pass through the limiting groove 201 and be inserted into the second support leg 110. The limiting groove 201 is provided with a first insertion hole 209 that matches the limiting rod 208, and the second support leg 110 is provided with a second insertion hole that matches the limiting rod 208.

[0039] The support block 205 is pushed to the right by the telescopic push rod 204. During the process of tilting the screening box 105, the mounting bracket 207 moves to the right along with the support block 205, causing the limiting plug 208 to separate from the first insertion hole 209 and the second insertion hole, releasing the plugging and fixing of the connection between the second support leg 110 and the limiting groove 201, so that the screening box 105 can be rotated and adjusted. Then the support block 205 will cooperate with the pad block 206 to adjust the tilting support of the screening box 105.

[0040] When the screening box 105 returns to a horizontal position, as the output shaft of the telescopic push rod 204 continues to shorten by a certain length, driving the support block 205 to continue moving to the left, the limiting plug rod 208 will pass through the first plug hole 209 and the second plug hole again, thereby plugging and fixing the connection between the limiting groove 201 and the second support leg 110, so that the screening box 105 can be stably connected to the base 103.

[0041] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the side of the screening box 105 is also provided with multiple mounting frames 301, and transparent observation windows 302 are provided in the mounting frames 301. Through the transparent observation windows 302, users can easily obtain the technical effects of the screening progress and other screening conditions of soybeans, so that users can easily arrange subsequent screening work.

[0042] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the mounting frame 301 is snapped and fixed to the side end of the screening box 105. A connecting plate 303 is also provided on the side end of the mounting frame 301. The connecting plate 303 is provided with connecting bolts 304 for screwing and fixing to the screening box 105. The screening box 105 is provided with threaded connection holes that match the connecting bolts 304. By simply snapping the mounting frame 301 and the screening box 105 together, and then passing the connecting bolts 304 through the connecting plate 303 and screwing them into the threaded connection holes, the mounting frame 301 and the screening box 105 can be flexibly fixed, thus allowing the transparent observation window 302 to be flexibly installed onto the screening box 105.

[0043] According to another embodiment of the present invention, such as Figure 3 As shown, an extension plate 119 is also provided on the side of the base 101, and an anchor bolt 120 for connecting to the ground is also provided on the extension plate 119. By simply having the anchor bolt 120 pass through the extension plate 119 and connect to the ground, the device can be effectively prevented from easily shifting during operation, making it easier for users to grade and screen soybeans.

[0044] According to another embodiment of the present invention, such as Figure 3 As shown, the base 101 is also provided with multiple guide cylinders 305, and the bottom of the base 103 is provided with guide rods 306 that are inserted and connected to the guide cylinders 305. During the vibration operation of the base 103 and the screening box 105 through the cooperation of the vibration motor 111 and the spring 102, the cooperation of the guide cylinders 305 and the guide rods 306 can prevent the base 103 and the screening box 105 from shifting laterally, and prevent the multiple springs 102 from easily deforming and being damaged.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
