Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a screening device for identifying blast-resistant soybean pods. Background Technology

[0002] A screening device for identifying blast-resistant soybeans uses physical screening and structural design to selectively collect and separate soybean individuals with excellent blast-resistant pod traits.

[0003] For example, the utility model patent application CN214812601U discloses a screening device for identifying shatter-resistant soybeans. In this device, "by turning on the motor, the second pulley rotates, which in turn drives the belt to rotate, which in turn drives the first pulley to rotate. The rotation of the second and first pulleys drives the first and second rotating shafts to rotate, which in turn drives the first and second rotating wheels to rotate. This causes the first and second fixed plates to shake up and down, causing the soybeans placed inside the soybean container to shake, and impurities in the soybeans to fall through the sieve." "The impurities will not get stuck inside the springs and other parts during the screening process and will not damage the invention." Although this device can separate impurities from soybeans during the screening process and will not get stuck inside the springs and other parts, it relies solely on mechanical shaking to separate impurities from soybeans. Due to the difference in physical properties between soybeans and impurities, some impurities have a strong adhesion to soybeans, and it is difficult to effectively separate them in a short time by shaking alone. Moreover, the amplitude and frequency of shaking are limited by the mechanical structure and cannot be flexibly adjusted according to the actual situation of soybeans and impurities, resulting in low screening efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A screening device for identifying blast-resistant soybean pods includes a support leg and guide rods uniformly fixedly installed on the upper surface of the support leg. A screening frame is fixedly installed on the upper end of the guide rod. A screening component is arranged inside the screening frame, and a shock-absorbing spring is fixedly installed on the lower surface of the screening frame. The lower end of the shock-absorbing spring is fixedly installed on the upper surface of the support leg. A cover plate is connected to the upper surface of the screening frame by a snap fastener. Snap hooks are fixedly arranged on both sides of the cover plate, and snap fastener seats are fixedly installed on both sides of the screening frame. A hopper is opened on the upper surface of the cover plate. The hopper has a constricted opening structure. A blowing component for the screening component is arranged on one side of the screening frame.

[0005] As an improvement to the above technical solution, the screening component includes a screen plate, a vibrating motor, a discharge port, and a slag discharge port. The screen plate is bolted to the inside of the screening frame. The vibrating motor is installed inside the screening frame. The bottom end of the screen plate has uniformly opened through holes. The vibrating motor is fixedly installed on the lower surface of the screening frame. The slag discharge port is opened on one side of the lower surface of the screening frame. The discharge port is opened through the bottom of the screen plate.

[0006] As an improvement to the above technical solution, the blowing assembly includes a fan, an air outlet pipe, and an air inlet pipe. The fan is fixedly installed on one side of the outer wall of the screening frame. One end of the air outlet pipe is located inside the fan, and the other end of the air outlet pipe extends through one side of the outer wall of the screening frame into the interior of the screening frame. Air outlets are evenly provided on the outer surface of the air outlet pipe, and one end of the air inlet pipe is located inside the fan.

[0007] As an improvement to the above technical solution, the fan is equipped with blower blades.

[0008] As an improvement to the above technical solution, a control panel is provided on the outside of the screening frame, and the control panel is electrically connected to the vibrating motor and the fan through wires.

[0009] The beneficial effects of this utility model are: 1. Through the uniformly opened through holes at the bottom of the sieve plate, the sieve plate vibrates under the action of the vibrating motor, allowing the blast-resistant soybeans that meet the through hole size to pass through the through holes and be discharged from the outlet, while larger impurities remain on the sieve plate, thus achieving the initial separation of blast-resistant soybeans from larger impurities and ensuring the purity of the blast-resistant soybeans screened out.

[0010] 2. A blower is installed to blow air into the screening frame through an air outlet pipe. The air outlets evenly distributed on the outer surface of the air outlet pipe can evenly disperse the air, blowing the material in the screening frame and blowing up light impurities such as dust and broken leaves mixed in with the blast-resistant soybeans. These impurities are then discharged from the screening frame through a suitable channel, further purifying the blast-resistant soybeans and improving the screening quality. When used in conjunction with the screening components, the blowing component processes the material from another dimension, removing light impurities that are difficult for the screening components to separate. Together with the screening components, they improve the screening effect of blast-resistant soybeans. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: In this embodiment, a screening device for identifying blast-resistant soybean pods includes a support leg 12 and a guide rod 11 uniformly fixedly installed on the upper surface of the support leg 12. A screening frame 3 is fixedly installed on the upper end of the guide rod 11. A screening component is provided inside the screening frame 3, and a shock-absorbing spring 10 is fixedly installed on the lower surface of the screening frame 3. The lower end of the shock-absorbing spring 10 is fixedly installed on the upper surface of the support leg 12. A cover plate 1 is connected to the upper surface of the screening frame 3 by a snap fastener. Snap hooks 4 are fixedly provided on both sides of the cover plate 1, and snap seats 5 are fixedly installed on both sides of the screening frame 3. A hopper 2 is opened on the upper surface of the cover plate 1. The hopper 2 has a constricted opening structure. A blowing component for the screening component is provided on one side of the screening frame 3.

[0015] In this embodiment, the support leg 12 provides a stable support foundation for the entire device, and the guide rod 11, which is evenly fixedly installed on the upper surface of the support leg 12, ensures that the screening frame 3 can only move vertically along the direction of the guide rod 11 under the action of the equipment operation, thus avoiding the shaking and deviation of the screening frame 3 and improving the accuracy and stability of screening. The shock-absorbing spring 10, which is fixedly installed between the lower surface of the screening frame 3 and the upper surface of the support leg 12, can reduce the impact of vibration on the overall device and extend the service life of the device.

[0016] Specifically, the screening components include a screen plate 14, a vibrating motor 13, a discharge port 6, and a slag discharge port 16. The screen plate 14 is bolted to the inside of the screening frame 3. The vibrating motor 13 is installed inside the screening frame 3. The bottom end of the screen plate 14 has evenly spaced through holes. The vibrating motor 13 is fixedly installed on the lower surface of the screening frame 3. The slag discharge port 16 is located on one side of the lower surface of the screening frame 3. The discharge port 6 is located through the bottom of the screen plate 14.

[0017] In this embodiment, the sieve plate 14 is vibrated by the vibration motor 13 through the uniformly opened through holes at the bottom. This allows the blast-resistant soybeans that fit the through hole size to pass through the through holes and be discharged from the discharge port 6, while larger impurities remain on the sieve plate 14. This achieves the initial separation of the blast-resistant soybeans from the larger impurities, ensuring the purity of the blast-resistant soybeans screened out. The slag discharge port 16 is located on one side of the lower surface of the screening frame 3. During the screening process, some smaller impurities or debris will fall off the sieve plate 14 with the vibration and be discharged through the slag discharge port 16, which allows for timely cleaning of the screened impurities and prevents impurities from accumulating in the screening frame 3, thus affecting the subsequent screening effect.

[0018] Specifically, the blowing assembly includes a blower 7, an air outlet pipe 8, and an air inlet pipe 9. The blower 7 is fixedly installed on one side of the outer wall of the screening frame 3. One end of the air outlet pipe 8 is located inside the blower 7, and the other end of the air outlet pipe 8 extends through one side of the outer wall of the screening frame 3 into the interior of the screening frame 3. Air outlets 15 are evenly distributed on the outer surface of the air outlet pipe 8, and one end of the air inlet pipe 9 is located inside the blower 7.

[0019] In this embodiment, when the blower 7 is working, it draws in air through the air inlet pipe 9 and then blows the air into the screening frame 3 through the air outlet pipe 8. The air outlets 15 evenly distributed on the outer surface of the air outlet pipe 8 allow the air to be evenly dispersed and blown towards the material, blowing away light impurities such as dust, broken leaves, and shriveled grains mixed in with the blast-resistant soybeans. The blowing action of the blower 7 can accelerate the separation speed of light impurities from the blast-resistant soybeans, reduce the residence time of impurities in the material, and avoid the repeated mixing of impurities with soybeans, thereby improving the overall screening efficiency and making the screening process faster.

[0020] Specifically, the blower 7 is equipped with a blower blade 17.

[0021] In this embodiment, the blower blade 17 can ensure that the fan 7 can stably generate wind power.

[0022] Specifically, a control panel is provided on the outside of the screening frame 3, and the control panel is electrically connected to the vibrating motor 13 and the fan 7 via wires.

[0023] In this embodiment, the control panel set outside the screening frame 3 is electrically connected to the vibrating motor 13 and the fan 7 via wires. The operator can conveniently control the start, stop, speed and other parameters of the vibrating motor 13 and the fan 7 through the control panel, realizing centralized control of the device and improving the convenience of operation.

[0024] The working principle and usage process of this utility model are as follows: Using the control panel, the vibration frequency of the vibrating motor 13 and the wind speed of the blower 7 are set according to the size of the blast-resistant soybean pods and the amount of impurities. The blast-resistant soybean pods to be screened are slowly poured into the screening frame 3 through the tapered hopper 2 on the upper surface of the cover plate 1. After feeding, the cover plate 1 is replaced on the screening frame 3. The vibrating motor 13 and the blower 7 are simultaneously started via the control panel. After the vibrating motor 13 starts working, the blast-resistant soybean pods continuously tumble and bounce on the screen plate 14. After the blower 7 starts, air is drawn in through the air inlet pipe 9. Air is then blown into the screening frame 3 through the air outlet pipe 8. The air outlets 15 evenly distributed on the outer surface of the air outlet pipe 8 allow the air to be evenly distributed and blown onto the material. The blast-resistant soybeans that match the diameter of the through holes at the bottom of the screen plate 14 can pass through the through holes smoothly and be discharged from the discharge port 6. The blast-resistant soybeans discharged from the discharge port 6 are qualified products after screening. The impurities discharged from the slag outlet 16 are removed. After the screening work is completed and the device has completely stopped running, the cover plate 1 is opened and the inside of the screening frame 3 is cleaned. Use tools such as a brush or blower 7 to remove the residual material and impurities on the screen plate 14.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
