[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: a polishing machine for rice production, including a polishing machine 1, with supporting legs 102 fixedly connected to the bottom of the polishing machine 1 near the edges on both sides, and slide rails 2 fixedly connected to the opposite surfaces of the two supporting legs 102, a screen frame 4 is provided under the polishing machine 1, and connecting sliders 403 are fixedly connected to both sides of the screen frame 4, and the connecting sliders 403 slide in cooperation with the slide rails 2, and an extrusion spring 201 is fixed in the slide rail 2, and the other end of the extrusion spring 201 is fixedly connected to the front end of the connecting slider 403, and two clamping grooves 401 are provided in the screen frame 4, and a filter frame 5 is slidably installed in the clamping groove 401, and a filter is embedded in the filter frame 5.

[0023] In this embodiment, the rice to be polished is fed into the polishing machine 1, and the polishing machine 1 is started to perform the polishing operation on the rice. The polished rice will be directly discharged and fall into the screen frame 4. The screen frame 4 is slidably matched with the slide rail 2 by the connecting slider 403, and then slidably installed under the polishing machine 1. The screen frame 4 can make reciprocating motion back and forth. At the same time, the end of the screen frame 4 is tilted downward, and the reciprocating motion can drive the rice falling into the screen frame 4 to slide downward. In the process of the rice moving downward, after entering the filter frame 5, the rice will be screened through the filter, and then the broken materials in the rice will be screened out. Two filter frames 5 are provided, and the filter mesh apertures inside the front and rear filter frames 5 are different. The filter mesh aperture at the rear is smaller and is used to screen out broken corners. The filter mesh aperture at the front is larger and can screen out broken rice. The broken materials are further screened, and the screened rice can be directly taken from the front end of the screen frame 4 for collection and packaging.

[0024] Among them, in order to achieve the purpose of reciprocating movement of the screen frame 4, this device adopts the following technical solutions: a discharge port 101 is fixedly connected to the bottom of the polishing machine 1, a slide groove 103 is opened on the front of the discharge port 101, a baffle 104 is slidably installed in the slide groove 103, a motor bracket 3 is fixedly connected to the back of the discharge port 101, a power motor 301 is fixedly connected to the bottom of the motor bracket 3, an elliptical driving wheel 302 is fixedly connected to the output end of the power motor 301, and the elliptical driving wheel 302 cooperates with the screen frame 4.

[0025] The polished rice is discharged through the discharge port 101, and the baffle 104 is inserted into the chute 103 to block the discharge of the rice from the discharge port 101, thereby controlling the discharge speed. Starting the power motor 301 can drive the elliptical driving wheel 302 to rotate. The elliptical driving wheel 302 cooperates with the screen frame 4. The rotation of the elliptical driving wheel 302 will continuously drive the squeeze screen frame 4 to move forward. When the screen frame 4 moves forward, the squeezing spring 201 is compressed. When the elliptical driving wheel 302 rotates to a flat position, the screen frame 4 will drive the squeezing spring 201 to move downward and backward to reset, thereby continuously moving back and forth to vibrate and screen the polished rice.

[0026] Among them, in order to facilitate the replacement of the filter frame 5, the present device adopts the following technical solutions: two collecting buckets 402 are fixedly connected to the bottom of the screen frame 4, and the collecting buckets 402 are connected to the inside of the clamping groove 401. Fixed frames 501 are fixed on both sides of the filter frame 5, and fixed holes 502 are provided in the fixed frames 501. A limiting groove 6 is provided on the top of the screen frame 4, and a limiting pin 601 is symmetrically slidably installed in the limiting groove 6. The limiting pin 601 cooperates with the fixing hole 502. A return spring 603 is fixed between the two limiting pins 601, and a displacement handle 602 is fixed on the limiting pin 601.

[0027] The screened broken materials and broken rice are collected and transported through the collecting bucket 402, and the return spring 603 can provide a certain thrust for the limit pin 601. The limit pin 601 is inserted into the fixing hole 502 under the thrust, thereby fixing the fixing frame 501 inside the clamping groove 401, and then fixing the filter frame 5 to the bottom of the screen frame 4. The moving displacement handle 602 can drive the limit pin 601 to move out of the fixing hole 502, thereby releasing the restriction on the fixing frame 501. At this time, the limit groove 6 can be easily taken out, which is convenient for replacement after the filter is damaged.

[0028] The working principle and usage process of the present invention are as follows: when in use, the device needs to be placed in a suitable position, and the rice to be polished is fed into the polishing machine 1. The polishing machine 1 can be started to polish the rice. The polished rice will be discharged from the discharge port 101 and fall onto the screen frame 4. Starting the power motor 301 can drive the elliptical driving wheel 302 to rotate. The elliptical driving wheel 302 cooperates with the extrusion spring 201 to drive the screen frame 4 to do reciprocating motion, thereby vibrating the rice inside the screen frame 4 to slowly move downward. When the rice moves downward and passes through the filter frame 5, it will be screened by the filter screen, and then the broken materials contained in the rice will be screened out. The screened rice can be directly taken from the front end of the screen frame 4 for collection and packaging.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
