Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, specifically a wind separation and impurity removal device for rice processing. Background Technology

[0002] In the rice processing industry, traditional impurity removal equipment often suffers from limited functionality and low processing efficiency. Most equipment uses only vibrating screening or pneumatic impurity removal, which is insufficient to simultaneously remove fine particulate impurities and light foreign objects from the rice, resulting in rice cleanliness failing to meet high-standard processing requirements. While some equipment combines multiple impurity removal methods, unreasonable structural design and poor coordination between functional modules increase energy consumption and equipment costs. Furthermore, the feeding speed is difficult to precisely control, making it unsuitable for processing different batches of rice. Components such as filters and dust collection bins are complex to disassemble, and cleaning impurities is time-consuming and labor-intensive. Rice collection also frequently suffers from scattering and blockages, severely impacting processing efficiency and continuity. As the industry's requirements for rice processing quality and production efficiency continue to rise... Utility Model Content

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1: As Figures 1-5 ,include:

[0028] The vibration separation assembly includes a vibrating plate 120, a vibration motor 130 fixedly installed on the bottom outer wall of the vibrating plate 120, a filter screen plate 140 provided above the vibrating plate 120, a filter screen 160 detachably and fixedly installed at the bottom of the filter screen plate 140, and a dust collection bin 150 provided at the bottom of the filter screen 160.

[0029] The rice silo 200 has a feeding pipe connected to its bottom. A blower 240 is fixedly installed on the inner wall of the rear end of the feeding pipe, and a cleanup flat pipe 230 is fixedly connected to the inner wall of the front end of the feeding pipe.

[0030] The specific application scenario of this embodiment is as follows: After the vibration motor 130 is started, it drives the vibration plate 120 to vibrate. The vibration is transmitted to the filter screen plate 140 and filter screen 160 above, so that the material placed on the filter screen is separated under the action of vibration. Fine impurities fall into the dust collection bin 150 below through the filter screen 160 and are collected. The rice in the rice bin 200 falls through the feeding pipe. The fan 240 at the rear end of the feeding pipe generates airflow, which blows the light impurities in the rice towards the impurity removal flat pipe 230 for discharge, thereby achieving the initial impurity removal of the rice.

[0031] Example 2: Figure 3 and Figure 4 The vibration separation assembly includes a base 100, four springs 110 are fixedly installed on the top outer wall of the base 100, a vibration plate 120 is fixedly installed on the outer wall of the springs 110, a vibration motor 130 is fixedly installed on the bottom outer wall of the vibration plate 120, a deflector wheel 131 is fixedly installed on the outer wall of the output shaft of the vibration motor 130, a filter screen plate 140 is fixedly installed on the top outer wall of the springs 110, a slot 141 is opened on the inner wall of the filter screen plate 140, a filter screen 160 is snapped into the top outer wall of the slot 141, a docking slot 142 is fixedly installed on the bottom outer wall of the filter screen plate 140, a dust collection bin 150 is inserted into the inner wall of the docking slot 142, and the dust collection bin 150 is magnetically sealed to the inner wall of the docking slot 142.

[0032] The specific application scenario of this embodiment is as follows: the vibration motor 130 drives the deflector wheel 131 to rotate. Due to the eccentric structure of the deflector wheel, centrifugal force is generated, causing the vibration plate 120 to vibrate under the elastic support of four springs 110. The vibration is transmitted to the filter screen plate 140, and the filter screen 160 fixed by the slot 141 vibrates accordingly. The material is screened during the vibration process, and impurities fall into the dust collection bin 150 below through the filter screen. The dust collection bin 150 is magnetically sealed to the docking slot 142 to prevent impurities from leaking out.

[0033] Example 3: Figures 4-6 A first ear hook 143 is fixedly installed on the outer wall of the front end of the filter screen plate 140. A connecting rod 144 is inserted into the inner wall of the first ear hook 143. A rice storage bin 300 is installed between the first ear hook 143 and the connecting rod 144. A second ear hook 320 is fixedly installed on the side wall of the rice storage bin 300 and is connected to the first ear hook 143. The connecting rod 144 is inserted into the inner wall of the second ear hook 320. A guide plate 310 is provided at the connection between the top of the rice storage bin 300 and the filter screen plate 140.

[0034] The specific application scenario of this embodiment is as follows: by passing the insertion rod 144 through the first ear hook 143 and the second ear hook 320 in sequence, the rice storage bin 300 is firmly connected to the filter screen plate 140. The guide plate 310 guides the qualified rice on the filter screen to smoothly enter the rice storage bin 300, realizing the centralized storage of rice, which is convenient for subsequent handling and processing.

[0035] Example 4: Figures 1-3 The interior of the rice silo 200 is cone-shaped. The bottom outer wall of the rice silo 200 is mounted on the top of the filter screen plate 140 via a support rod 210. The bottom outer wall of the discharge pipe is rotatably connected to the discharge plate 250 via a shaft pin 260 and a rotating block. The rotating part of the discharge plate 250 is equipped with damping for self-locking the rotation of the discharge plate 250. A handwheel is fixedly installed on the outer wall of the shaft pin 260.

[0036] The specific application scenario of this embodiment is as follows: The conical design of the rice silo 200 facilitates the concentrated feeding of rice to the bottom. By rotating the handwheel, the shaft pin 260 is rotated, which in turn causes the feeding plate 250 to rotate around the shaft pin 260. The damping of the rotating part of the feeding plate 250 achieves self-locking. The opening size of the feeding pipe can be adjusted to control the feeding speed and flow rate of rice, thereby meeting different usage needs.

[0037] The working principle of this utility model is as follows: When used by those skilled in the art, the vibration motor 130 is installed on the bottom outer wall of the vibration plate 120. After starting, it drives the vibration plate 120 to vibrate. The filter screen plate 140 above the vibration plate 120 and the filter screen 160 fixed at its bottom vibrate accordingly. The rice and impurities placed on the filter screen 160 are separated due to the difference in particle size under the action of vibration. The fine impurities pass through the filter screen 160 and fall into the dust collection bin 150 below. The rice in the rice bin 200 falls through the feeding pipe connected to the bottom. The fan 240 on the inner wall of the rear end of the feeding pipe generates airflow, which blows the light impurities in the rice towards the impurity removal flat pipe 230 fixed on the inner wall of the front end of the feeding pipe and discharges them, thus completing the rice processing. After initial impurity removal, qualified rice grains are screened on the filter screen 160. Guided by the guide plate 310, the rice grains pass through the first ear hook 143 on the front outer wall of the filter screen plate 140 and the second ear hook 320 on the side wall of the rice collection bin 300 via the insertion rod 144, and enter the rice collection bin 300 for centralized storage. The inside of the rice bin 200 is conical, which facilitates the concentration of rice grains at the bottom. The outer wall of the bottom end of the discharge pipe is rotatably connected to the discharge plate 250 via the shaft pin 260 and the rotating block. The handwheel fixed on the outer wall of the shaft pin 260 can drive the shaft pin 260 to rotate, thereby causing the discharge plate 250 to rotate. The damping of the rotating part of the discharge plate 250 is used to achieve self-locking, thereby adjusting the size of the discharge pipe opening and precisely controlling the discharge speed and flow rate of rice grains.
