[0028] 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.

[0029] Reference Figure 1 - Figure 3The utility model provides an embodiment: a multifunctional amplifying device based on a combined rice mill, comprising a bottom plate 1 for supporting the entire device, a rice mill 3 for processing rice grains is installed on the top of the bottom plate 1, and a control console 2 for controlling the operation of the rice mill 3 is installed near the right end of the top of the bottom plate 1. The rice mill 3 and the control console 2 are prior art, and the two are electrically connected by wires and can start working when the power is turned on. Due to the prior art and the fact that it can be implemented by people in this field, this case will not be described in detail. The rice mill 3 The right end is equipped with a support base 4 for supporting the driving component 5, and the top of the support base 4 is equipped with a driving component 5 for driving the screening mechanism 6. The top of the rice milling machine 3 is equipped with a screening mechanism 6 for separating rice and debris. The screening mechanism 6 includes a vibration component 61 for realizing the screening function and an adjustment component 62 for adjusting the vibration amplitude of the vibration component 61. The vibration component 61 includes a screening box 617 for accommodating screened rice. The bottom end of the screening box 617 is fixedly connected to the top of the rice milling machine 3, and the inner wall of the screening box 617 is fixedly connected to the top of the rice milling machine 3. The bottom end of the sliding sleeve 615 passes through and is slidably connected to the support rod 614 for supporting the sieve plate 613 to move up and down. The bottom end of the support rod 614 is fixedly connected to the sieve plate 613 for realizing the screening function. The top end of the support rod 614 is fixedly connected to a return spring 616 for driving the support rod 614 to return. The top end of the return spring 616 is fixedly connected to the inner wall of the sliding sleeve 615. When the return spring 616 contracts, it will generate a downward thrust, which can push the support rod 614 to return to its original position. The rod 614 moves downward and resets, and the front end of the screening box 617 passes through and is slidably connected to a rotating shaft 611 for supporting the rotation of the cam 612. The outer wall of the rotating shaft 611 is fixedly connected to the cam 612 in multiple groups. When the rotating shaft 611 rotates, the cam 612 will rotate synchronously with it. When the cam 612 rotates, it will push the screen plate 613 to move upward. At the same time, the support rod 614 will push the screen plate 613 downward under the action of the reset spring 616 to move it downward and reset. Repeating this process once is one vibration screening.

[0030] Reference Figure 1 - Figure 3The driving assembly 5 includes a driving motor 51 for providing power for the rotation of the rotating shaft 611. The bottom end of the driving motor 51 is fixedly connected to the top of the support base 4. The front end outer wall of the rotating shaft 611 is fixedly connected with a transmission wheel 53 for receiving the rotation. The output shaft of the driving motor 51 is connected to the transmission wheel 53 through a belt 52. Starting the driving motor 51 can drive the transmission wheel 53 to rotate, thereby driving the rotating shaft 611 to rotate. The adjusting assembly 62 includes a handle 621 for facilitating the operator to move the sliding sleeve 615. The right end of the handle 621 is fixedly connected to the left end of the sliding sleeve 615. When the handle 621 moves up and down, the sliding sleeve 615 will be driven to move synchronously. The left end of the screening box 617 is provided with a slide groove 623 for the sliding of the handle 621. The handle 621 slides in the slide groove 62 3, when the handle 621 slides on the inner wall of the slide 623, the sliding sleeve 615 will block the remaining vacancies of the slide 623, so as to prevent rice from leaking out of the slide 623, and the inner wall of the handle 621 is slidably connected with a block 622 for fixing the handle 621. The rear end of the slide 623 is provided with positioning grooves 624 for accommodating the block 622, and the number is multiple. The block 622 is inserted into the inner wall of the positioning groove 624. By adjusting the block 622 and inserting it into different positioning grooves 624, the upper and lower positions of the block 622 can be changed. The inner wall of the handle 621 is fixedly connected near the left end with a slide rod 625 for guiding the movement of the block 622. The block 622 slides on the outer wall of the slide rod 625. The movement of the block 622 is guided by the slide rod 625 to ensure that the block 622 keeps moving horizontally.

[0031] Reference Figure 1 - Figure 3 The left end of the card block 622 is fixedly connected with a positioning spring 626 for pushing the card block 622. The left end of the positioning spring 626 is fixedly connected to the inner wall of the handle 621. The positioning spring 626 will always push the card block 622 to the right. The card block 622 is set in a U shape. The card block 622 can be driven to move by toggling the middle crossbar position of the card block 622. There are multiple groups of slide bars 625 and positioning springs 626. The multiple groups of slide bars 625 and positioning springs 626 are symmetrically arranged with the center line of the card block 622 as the symmetry axis. The two groups of slide bars 62 5 and the positioning spring 626 will push the block 622 synchronously from two points, so as to ensure the stable movement of the block 622. There are multiple groups of adjustment components 62, and the multiple groups of adjustment components 62 are symmetrically arranged with the center line of the screening box 617 as the symmetry axis. When the position of the screen plate 613 needs to be adjusted, the two groups of adjustment components 62 need to be adjusted at the same time. In this way, when in use, the displacement of the screen plate 613 caused by the loosening of a single group of adjustment components 62 can be prevented. The top of the screening box 617 is fixedly connected to a discharge hopper 7 for facilitating the operator to pour the material.

[0032] Working principle: When rice milling is required, the rice milling machine 3 must be started first, and then the driving motor 51 can be started to drive the transmission wheel 53 to rotate. The rotation of the transmission wheel 53 will drive the cam 612 to rotate. The rotation of the cam 612 will push the sieve plate 613 to move upward. The upward movement of the sieve plate 613 will push the support rod 614 to move upward. The upward movement of the support rod 614 will squeeze the return spring 616 to contract it. After the return spring 616 contracts, it will accumulate elastic force. When the cam 612 no longer squeezes the sieve plate 613, the return spring 616 will recover and push the support rod 614 to drive the sieve plate 613 to move downward and reset, so that continuous vibration can be achieved.

[0033] When the vibration amplitude of the sieve plate 613 needs to be adjusted, the two sets of blocks 622 can be moved outward and out of the positioning groove 624 at the same time, and then the handle 621 can be moved up and down to drive the sliding sleeve 615 to move up and down. When it is adjusted to the appropriate position, the block 622 can be released, and the positioning spring 626 will push the block 622 to the middle position to reinsert it into the positioning groove 624. At this time, the two sets of handles 621 will be re-fixed, and the sliding sleeve 615 will change the lowest position that the sieve plate 613 can reach when it moves up and down. By changing the lowest point of the movement of the sieve plate 613, the amplitude of the sieve plate 613 can be changed. The overall device has good applicability when used.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
