Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, and specifically, to a bean planting screening device. Background Art
[0002] For the screening of bean planting by existing equipment, the seeds floating on the water surface are fished out with a fishing net. After the underdeveloped seeds are fished out, the top cover is installed on the screening box, and the motor in the screening component is started. The motor drives the cam to rotate, and the cam drives the sieve plate to move up and down through the transmission rod, so as to screen the seeds on the sieve plate. The seeds with smaller particles will be screened onto the bottom cover, and the seeds with larger particles will remain on the sieve plate; after the screening is completed, the drain pipe is opened. A sieve is arranged in the drain pipe to prevent the seeds on the bottom cover from being washed away.
[0003] The above-mentioned equipment cannot collect the larger particle seeds while collecting the smaller particle seeds. The smaller particle seeds are screened onto the bottom cover and the sieve in the drain pipe is set to prevent the seeds from being washed away during drainage. However, the small particle seeds on the top of the sieve are easy to block the sieve with the water flow. The main reason is that the smaller particle seeds will accumulate on the sieve, especially in the place where the water flow is stronger at the drain pipe outlet. They are easy to be driven and concentrated in the narrow area of the sieve, resulting in blockage. Therefore, a bean planting screening device is needed. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.
[0023] Bean planting screening equipment generally refers to equipment used for screening and cleaning seeds or beans, aiming to remove impurities, classify, and select seeds. These equipment usually classify and separate according to the size, shape, and density of the seeds.
[0024] Existing equipment cannot collect larger particle seeds while collecting smaller particle seeds. The smaller particle seeds are screened to the bottom cover and the setting of the inner screen of the drain pipe prevents the seeds from being washed away during drainage. However, the small particle seeds on the top of the screen are prone to block the screen along with the water flow. The main reason is that the smaller particle seeds will accumulate on the screen, especially in places where the water flow is stronger at the drain pipe outlet, and they are easily driven and concentrated in the narrow area of the screen, resulting in blockage. Please refer to Figures 1-4, An embodiment provides a bean planting screening device, including a screening box 1, an observation window 11 fixed to the front side of the screening box 1, and a drain pipe 12 fixedly connected to the side of the screening box 1. Inside the screening box 1, two mounting plates 6 are symmetrically arranged. Between the two mounting plates 6, an upper sieve plate 2 and a lower sieve plate 3 are arranged in sequence from top to bottom. The sieve holes of the upper sieve plate 2 are larger than those of the lower sieve plate 3. The size of the sieve holes of the upper sieve plate 2 determines the maximum allowable size of the seed particles passing through, while the sieve holes of the lower sieve plate 3 determine the minimum allowable size of the seed particles passing through. The seed particles pass through the sieve plates with different sieve holes according to their sizes. Larger seed particles will be screened out on the upper sieve plate 2, while smaller seed particles can pass through the upper sieve plate 2 and continue to move downward, and are further screened by the lower sieve plate 3, which can effectively classify and separate according to the size of the seed particles to ensure that the finally screened seeds meet the requirements.
[0025] Reference Figure 3As shown, the existing equipment cannot collect larger particle seeds while collecting smaller particle seeds. The smaller particle seeds are screened onto the bottom cover, and the setting of the sieve in the drain pipe prevents the seeds from being washed away during drainage. However, the small particle seeds on the top of the sieve are prone to clogging the sieve with the water flow. The main reason is that the smaller particle seeds will accumulate on the sieve, especially in places where the water flow is stronger at the drain pipe outlet. They are easily driven and concentrated in the narrow area of the sieve, resulting in clogging. In order to collect larger particle seeds while collecting smaller particle seeds, the following settings are made. Screening mechanisms 5 for screening the seed particle sizes are provided on the opposite sides of the two mounting plates 6. The screening mechanism 5 includes a waterproof cover 51 fixed to the side of the mounting plate 6 to protect the motor from water erosion, especially when operating in water. Its function is to prevent moisture, humidity or liquid from entering the motor, thus protecting the normal operation of the motor and extending its lifespan. The inner wall of the waterproof cover 51 is fixedly connected with a motor, and the motor is a forward and reverse motor. The output end of the motor is fixedly connected with a linkage rod 52. The end face of the linkage rod 52 penetrates the inner wall of the waterproof cover 51 and extends to the outside of the waterproof cover 51. A power rod 53 is fixedly connected to the outer wall of the linkage rod 52. A semi-circular rotating block is fixedly connected to the side of the power rod 53 close to the mounting plate 6. An arc-shaped rounded groove for the semi-circular rotating block to slide is provided on the side of the mounting plate 6 close to the power rod 53. The end face of the power rod 53 is movably connected with a push-pull rod 54. The end of the push-pull rod 54 away from the power rod 53 is fixedly connected with a movable plate 55. A transverse movement groove is horizontally provided on the side of the mounting plate 6 close to the movable plate 55. A transverse movement block is fixedly connected to the side of the movable plate 55 close to the mounting plate 6. The transverse movement block slides left and right along the length direction of the transverse movement groove. Two movable rods 56 are movably connected to the inner wall of the movable plate 55. The ends of the two movable rods 56 away from the movable plate 55 are respectively movably connected with the upper sieve plate 2 and the lower sieve plate 3. Vertical movement blocks are fixedly connected to the sides of the upper sieve plate 2 and the lower sieve plate 3 close to the movable plate 55. Vertical movement grooves are vertically provided on the sides of the mounting plate 6 close to the upper sieve plate 2 and the lower sieve plate 3. The vertical movement blocks slide up and down along the height direction of the vertical movement grooves. Start the motor to drive the output end to drive the linkage rod 52 to rotate forward by 80°. The rotation of the linkage rod 52 drives the power rod 53 to rotate. The rotation of the power rod 53 causes the push-pull rod 54 to pull the movable plate 55. The movement of the movable plate 55 gradually expands the angle between the two movable rods 56, thereby pushing the upper sieve plate 2 and the lower sieve plate 3 to move away from each other. When the motor drives the driving rod 52 to rotate reversely by 80°, the angle between the two movable rods 56 gradually decreases, thereby pulling the upper sieve plate 2 and the lower sieve plate 3 to move relatively. Through the cyclic back-and-forth vertical movement of the upper sieve plate 2 and the lower sieve plate 3, the upper sieve plate 2 and the lower sieve plate 3 can effectively classify according to the seed particle sizes, achieving the purpose of collecting larger particle seeds while collecting smaller particle seeds.
[0026] Reference Figures 2-4As shown in the figure, a picking and placing mechanism 4 is provided at the top of the screening box 1 for taking out the upper sieve plate 2 and the lower sieve plate 3 outside the screening box 1. The picking and placing mechanism 4 includes a long rod 43 fixed to the top of the mounting plate 6. The top end of the long rod 43 is fixedly connected with a frame-shaped frame 42. An opening-shaped groove 45 adapted to the frame-shaped frame 42 is formed at the top of the screening box 1. Anti-slip lines 44 are adhered to the inner wall of the opening-shaped groove 45. The anti-slip lines 44 are made of rubber to increase the firmness of the frame-shaped frame 42 stuck in the opening-shaped groove 45. The surface of the anti-slip lines 44 is in close contact with the outer wall of the frame-shaped frame 42. A handle 41 is fixedly connected to the top of the frame-shaped frame 42 for taking out the upper sieve plate 2 and the lower sieve plate 3 outside the screening box 1. After grading according to the size of the seed particles, the user holds the handle 41 with both hands and lifts it upward, so that the frame-shaped frame 42 moves away from the opening-shaped groove 45, causing the upper sieve plate 2 and the lower sieve plate 3 to move out of the screening box 1. The removed upper sieve plate 2 and lower sieve plate 3 can be conveniently placed on the workbench or the processing area, enabling the user to more easily further process seeds of different sizes, such as cleaning, packaging or further grading. Moreover, the removal of the upper sieve plate 2 and the lower sieve plate 3 allows the space inside the screening box 1 to be reused or cleaned, which helps to maintain the cleanliness and efficiency of the work area.
[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
