Description

Technical Field

[0001] This utility model relates to the field of rice, specifically to a rice screening device for rice processing. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. After being processed into rice, light impurities such as dust and bran can be removed by air sieving, as shown in patent number CN. 218309239U provides a rice screening device for rice processing, belonging to the technical field of rice processing equipment. It includes a top plate, with angle irons fixedly connected to the four corners of the lower surface of the top plate. A screen basket is rotatably installed between two angle irons, and a fixing plate is fixedly installed between the other two angle irons. A common motor with an output end is fixedly installed on the fixing plate. Two rotating seats are fixedly installed on the bottom surface of the screen basket near the fixing plate, and rollers are rotatably installed on each of the two rotating seats. A cam is fixedly installed on the output end of the common motor, and the cam is tangent to the two rollers. A feeding hopper is fixedly installed on the top plate, and a feeding roller with through holes is rotatably connected inside the feeding hopper. One end of the feeding roller passes through the feeding hopper, and a limiter with evenly spaced limiting holes is coaxially fixedly connected to that end. Because the screening time of the screen is relatively short, some broken rice grains are easily mixed with whole rice grains and flow out from the discharge hopper. Utility Model Content

[0003] The purpose of this invention is to provide a rice screening device for rice processing, which solves the problem that the device easily causes some broken rice grains to mix with whole rice grains and flow out from the discharge hopper.

[0004] To achieve the above objectives, this utility model provides a rice screening device for rice processing. The rice screening device includes a base, a support plate on the base, a limit rod on the support plate, an mounting plate on the base, a fixing plate on the mounting plate, and a support rod on the fixing plate. The support rod is connected to the limit rod via a spring. A screen is mounted on the mounting plate, and a limit plate is mounted on the screen. A baffle is slidably mounted on the limit plate, and the limit plate and the baffle surround the screen on the mounting plate. A pin is slidably mounted on the limit plate, and sliding the pin can fix the baffle on the limit plate. A connecting rod is mounted on the mounting plate, and a second cam is mounted on the connecting rod. A rotating rod is rotatably mounted on the base, and a first cam is mounted on the rotating rod. Rotating the rotating rod can cause the first cam to collide with the second cam, thereby driving the screen to reciprocate.

[0005] Preferably, one end of the spring is connected to the support plate, and the other end is connected to the fixing plate.

[0006] Preferably, the pin is provided with a handle.

[0007] Preferably, the mounting plate is provided with a return spring, one end of which is connected to the handle and the other end is connected to the limiting plate.

[0008] Preferably, the limiting plate is provided with a groove, and the baffle is slidably disposed in the groove.

[0009] Preferably, the limiting plate is provided with a first hole, the baffle is provided with a second hole, and the pin passes through the first hole and the second hole in sequence to fix the baffle on the limiting plate.

[0010] Preferably, a motor is provided on the base, and the output shaft of the motor is connected to the rotating rod.

[0011] This utility model provides a rice screening device for rice processing. The rice screening device includes a base, a support plate on the base, a limit rod on the support plate, an mounting plate on the base, a fixing plate on the mounting plate, a support rod on the fixing plate, and the support rod connected to the limit rod by a spring. A screen is mounted on the mounting plate, a limit plate is mounted on the screen, and a baffle is slidably mounted on the limit plate. The limit plate and the baffle surround the screen on the mounting plate. A pin is slidably mounted on the limit plate, and sliding the pin can fix the baffle on the limit plate. A connecting rod is mounted on the mounting plate, and a second cam is mounted on the connecting rod. A rotating rod is rotatably mounted on the base, and a first... The cam, when rotated, causes the first cam to collide with the second cam, thereby driving the screen to reciprocate. When using this device, the baffle must first be fixed to the limiting plate with a pin. Then, the motor is started, causing the motor to drive the rotating rod to rotate. During rotation, the rotating rod drives the first cam to rotate, and the first cam collides with the second cam, causing the mounting plate to move upwards. When the first cam separates from the second cam, the mounting plate, through the spring force, drives the rice on the screen to be sieved. (The mounting plate is tilted on the base to facilitate sweeping out and collecting whole rice grains from the screen). This simple structure allows whole rice grains to remain on the screen for a longer time, thus reducing the mixing of broken and whole rice grains.

[0012] Beneficial effects: By fixing the baffle to the limit plate with a pin, the motor is started, causing the motor to drive the rotating rod to rotate. During the rotation of the rotating rod, the first cam rotates and abuts against the second cam, thereby causing the mounting plate to move upward. When the first cam separates from the second cam, the mounting plate uses the elastic force of the spring to sieve the rice on the screen, thus allowing the device to keep whole rice grains on the screen for a longer time, thereby reducing the mixing of broken rice grains and whole rice grains.

The screening device includes a base 1, a support plate 2 on the base 1, a limit rod 3 on the support plate 2, an mounting plate 5 on the base 1, a fixing plate 6 on the mounting plate 5, and a support rod 7 on the fixing plate 6. The support rod 7 is connected to the limit rod 3 by a spring 4. A screen 9 is mounted on the mounting plate 5, a limit plate 8 is mounted on the screen 9, and a baffle 10 is slidably mounted on the limit plate 8. The limit plate 8 is connected to the limit rod 3 by a spring 4. The baffle 10 surrounds the screen 9 on the mounting plate 5. A pin 11 is slidably provided on the limiting plate 8. Sliding the pin 11 can fix the baffle 10 on the limiting plate 8. A connecting rod 17 is provided on the mounting plate 5. A second cam 18 is provided on the connecting rod 17. A rotating rod 15 is rotatably provided on the base 1. A first cam 16 is provided on the rotating rod 15. Rotating the rotating rod 15 can cause the first cam 16 to collide with the second cam 18, thereby causing the screen 9 to reciprocate.

[0022] The working principle of this utility model is as follows: When using this device, the baffle needs to be fixed to the limiting plate with a pin first. Then, the motor is started, which drives the rotating rod to rotate. During the rotation of the rotating rod, the first cam rotates. During the rotation of the first cam, it abuts against the second cam, thereby causing the mounting plate to move upward. When the first cam separates from the second cam, the mounting plate uses the elastic force of the spring to sieve the rice on the screen. (The mounting plate is set at an angle on the base to facilitate sweeping out and collecting the whole rice grains on the screen.) Through this simple structure, the device can make the whole rice grains stay on the screen for a longer time, thereby reducing the mixing of broken rice grains and whole rice grains.

[0023] In a preferred embodiment of this utility model, one end of the spring 4 is connected to the support plate 2, and the other end is connected to the fixing plate 6. This is to facilitate the spring force to drive the screen to move repeatedly.

[0025] In a preferred embodiment of this utility model, a return spring 13 is provided on the mounting plate 5. One end of the return spring 13 is connected to the handle 12, and the other end is connected to the limiting plate 8. This is to facilitate the handle to engage the pin with the baffle through the elastic force of the return spring.

[0026] In a preferred embodiment of this utility model, the limiting plate 8 is provided with a groove, and the baffle 10 is slidably disposed in the groove, which is to facilitate the limiting of the baffle.

[0027] In a preferred embodiment of this utility model, the limiting plate 8 is provided with a first hole, the baffle 10 is provided with a second hole, and the pin 11 passes through the first hole and the second hole in sequence to fix the baffle 10 on the limiting plate 8. This is to facilitate the disassembly of the baffle and to facilitate the sweeping out and packing of intact rice grains from the screen.

[0028] In a preferred embodiment of this utility model, a motor 14 is provided on the base 1, and the output shaft of the motor 14 is connected to the rotating rod 15. This is to facilitate the motor to drive the rotating rod to rotate.
