A white kidney bean screening device

Abstract

This utility model belongs to the field of white kidney bean processing technology, specifically disclosing a white kidney bean screening device, including a base plate. A table is installed between the front and back of the left side of the top of the base plate, and a left frame is fixed between the front and back of the left side of the top of the table. A right frame is provided on the right side of the left frame. A lead screw is movably connected between the front and back of the center of the left frame, and a threaded sleeve is threadedly connected to the outside of the lead screw. This white kidney bean screening device uses a guide plate movably connected to the right side outside the threaded sleeve. The speed at which kidney beans fall from the hopper is controlled by a valve. When the guide plate stops below the valve, it collects the kidney bean grains. Then, a motor rotates the lead screw and guides the threaded sleeve to move back and forth. A motor adjusts the angle of the guide plate. By moving back and forth, the white kidney beans are spread on the surface of the conveyor belt and then sent to the right side for the color sorter's camera to capture images for sorting. This solves the problem of inconvenient white kidney bean transportation.

Description

Technical Field

[0001] This utility model relates to the field of white kidney bean processing technology, specifically a white kidney bean screening device. Background Technology

[0002] White kidney beans, also known as string beans, sword beans, or green beans, are a common type of edible bean. The outer surface of white kidney beans is kidney-shaped and very smooth. Most of them are pure white or milky white and are larger in size than other beans (red beans, mung beans, etc.). They can be used for stewing or making fillings for buns, mooncakes, and other foods.

[0003] Kidney beans with insect holes on their surface are considered substandard, as are those whose color does not meet requirements. A screening device is needed to remove substandard kidney beans and collect them separately. However, if such a screening device is laid directly on the conveyor through a pipe, the beans will fall to different locations. If the beans overlap, it will affect the clarity of the camera when capturing white kidney beans.

[0004] Now, a novel white kidney bean screening device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a white kidney bean screening device to solve the problem of inconvenient white kidney bean transportation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a white kidney bean screening device, comprising a base plate, a table body installed between the front and back of the left side of the top of the base plate, and a left frame body fixed between the front and back of the left side of the top of the table body, a right frame body provided on the right side of the left frame body, a lead screw movably connected between the front and back of the center of the interior of the left frame body, and a threaded sleeve threadedly connected to the outer side of the lead screw, a second motor installed inside the right side of the threaded sleeve, a guide plate movably connected to the right side of the outer side of the threaded sleeve, a limit plate fixed between the front and back of the lower center of the interior of the left frame body, a first motor installed at the front end of the outer side of the left frame body, a hopper provided above the left and right frames, a conveyor installed between the left and right sides of the interior of the table body, a color sorter fixed between the front and back of the right side of the top of the table body, and cameras installed on both sides inside the color sorter.

[0007] As a further technical solution of this utility model, the output end of the first motor is fixedly connected to the lead screw at the rear, the threaded sleeve moves back and forth along the surface of the limiting plate, the output end of the second motor is fixedly connected to the guide plate on the right side, and the front and rear ends of the bottom of the right frame are fixedly connected to the table body respectively.

[0008] As a further technical solution of this utility model, insert rods are fixed at the four corners of the lower part of the hopper, vertical grooves are provided at the top of the front and rear ends of the left and right frames, and silicone sleeves are fixed in the vertical grooves. Springs are fixed at the top of the left and right frames, a vibrator is installed on the left side of the hopper, and a valve is installed at the lower left corner of the hopper.

[0009] As a further technical solution of this utility model, the bottom of the insertion rod is embedded in the silicone sleeve, and the top of the spring is fixedly connected to the hopper.

[0010] As a further technical solution of this utility model, an air duct is provided on the right side of the interior of the table body, a nozzle is fixed between the front and back on the right side of the exterior of the table body, and an air pump is installed on the right side of the bottom of the table body.

[0011] As a further technical solution of this utility model, a limiting frame is fixed on the right side of the top of the substrate, and a shell is fixed in the limiting frame. Cavities are respectively provided on both sides inside the shell, and a frame is provided inside the cavity. A filter screen is fixed inside the bottom of the frame, and feet are respectively fixed on both sides of the lower part of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the white kidney bean screening device not only realizes sorting feeding and prevents kidney bean grains from clogging the pipe, but also makes it easy to screen kidney beans and dust particles. A guide plate is movably connected to the right side of the threaded sleeve. The speed at which the kidney beans fall from the hopper is controlled by a valve. When the guide plate stops behind the valve, it catches the kidney bean grains. Then, motor one rotates the screw and guides the threaded sleeve to move back and forth. Motor two adjusts the angle of the guide plate. By moving back and forth, the white kidney beans are spread on the surface of the conveyor belt and then sent to the right side for the color sorter's camera to take pictures, ready for blowing and sorting. By fixing insert rods at the four corners of the lower exterior of the hopper, in order to prevent the pipe in the lower left corner of the hopper from becoming blocked and affecting the valve discharge, the vibrator installed on the exterior of the left side of the hopper can be activated periodically. The vibration generated is sufficient to shake off the blocked beans. The four sets of insert rods at the bottom of the hopper are respectively embedded in the vertical grooves at the top of the right and left frames. When the hopper shakes, the insert rods rub against the silicone sleeve under the support of the spring, thereby maintaining the stability of the hopper. Only the valve pipe needs to be cleared. By fixing the outer shell in the limiting frame, the outer shell is pushed along the base plate from the right side until the left side of the outer shell contacts the limiting frame. When the air pump sprays air through the air passage and nozzle to filter white kidney beans, the frames in the cavities on both sides hold different beans. After the process is finished, the outer shell is removed and the frame with the feet is taken out by holding the handle. After shaking for a while, the beans and dust particles can be separated, ensuring the cleanliness of the white kidney beans. Attached Figure Description

Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the speed at which the kidney beans fall from the hopper 5 is controlled by valve 20, and when the guide plate 18 stops behind the valve 20, it catches the kidney beans. Then, motor 1 27 rotates the screw 24 and guides the threaded sleeve 25 to move back and forth. Motor 2 29 adjusts the angle of the guide plate 18, and the white kidney beans are evenly spread on the surface of the conveyor belt 3 by moving back and forth.

[0017] Insert rods 22 are fixed at the four corners of the lower exterior of the hopper 5. Vertical grooves 23 are provided at the top of the front and rear ends of the left frame 19 and the right frame 6, and silicone sleeves 28 are fixed in the vertical grooves 23. Springs 21 are fixed at the top of the left frame 19 and the right frame 6. A vibrator 4 is installed on the left side of the exterior of the hopper 5. A valve 20 is installed at the lower left corner of the exterior of the hopper 5. The bottom of the insert rods 22 is embedded in the silicone sleeves 28. The tops of the springs 21 are all fixedly connected to the hopper 5. Specifically, such as Figure 1 and Figure 4 As shown, in order to prevent the pipe in the lower left corner of the hopper 5 from becoming blocked and affecting the discharge of the valve 20, the vibrator 4 installed on the outside of the left side of the hopper 5 can be activated periodically. The vibration generated is sufficient to shake off the blocked beans. The four sets of insert rods 22 at the bottom of the hopper 5 are respectively embedded in the vertical grooves 23 at the top of the right frame 6 and the left frame 19. When the hopper 5 shakes, the insert rods 22 rub against the silicone sleeve 28 under the support of the spring 21, thereby maintaining the stability of the hopper 5.

[0018] An air duct 9 is provided on the right side inside the table body 2. A nozzle 10 is fixed between the front and back on the right side outside the table body 2.

The electrical connection relationship and control method between them are existing technologies, so they will not be described in detail. Working Principle: In use, to prevent blockage of the pipe in the lower left corner of the hopper 5 from affecting the discharge from valve 20, the vibrator 4 installed externally on the left side of the hopper 5 can be periodically activated. The resulting vibration is sufficient to shake off any blocked beans. The four sets of insert rods 22 at the bottom of the hopper 5 are respectively embedded in the vertical grooves 23 at the top of the right frame 6 and the left frame 19. When the hopper 5 shakes, the insert rods 22, supported by the spring 21, rub against the silicone sleeve 28, thus maintaining the stability of the hopper 5. The valve 20 controls the speed at which the beans fall from the hopper 5. When the guide plate 18 stops behind the valve 20, it collects the beans. Then, the motor... 27 Rotate the lead screw 24 and guide the threaded sleeve 25 to move back and forth. Adjust the angle of the guide plate 18 by the motor 29. Spread the white kidney beans on the surface of the conveyor belt 3 by moving back and forth. Then send them to the camera 8 of the color sorter 7 on the right side to take pictures.
