[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] See also Figure 1 to Figure 5 A uniform feeding device for photovoltaic high-purity quartz sand includes a collection bin 1, the upper surface of which is fixedly connected to a feed trough 2. The quartz sand containing agglomerates can be poured into the interior of the collection bin 1 through the set feed trough 2, which is convenient for subsequent processing of the quartz sand.

[0023] A crushing assembly 3 is provided inside the aggregate bin 1, and the crushing assembly 3 includes a first motor 301 and a second gear 304. The first motor 301 is installed on the left side of the aggregate bin 1. The first motor 301 is installed on the left side of the aggregate bin 1 by bolts, which is convenient for subsequent disassembly and maintenance. The output end of the first motor 301 is fixedly connected to the first crushing roller 302, and the end of the first crushing roller 302 away from the first motor 301 passes through the outer surface of the aggregate bin 1 and is rotatably connected to the inner wall of the crushing bin 4. The outer surface of the first crushing roller 302 is fixedly connected to the first gear 303, and the outer surface of the first gear 303 is meshed with the outer surface of the second gear 304.

[0024] By utilizing the meshing relationship between the first gear 303 and the second gear 304, the second gear 304 can be driven to rotate when the first gear 303 rotates, so that the first crushing roller 302 and the second crushing roller 305 can move relative to each other, which is convenient for crushing quartz sand. The second crushing roller 305 is fixedly connected to the inner wall of the second gear 304, and the outer surfaces of the first crushing roller 302 and the second crushing roller 305 are both provided with a group of crushing blocks, which is convenient for crushing quartz sand.

[0025] One end of the second crushing roller 305 away from the second gear 304 is rotatably connected to the inner wall of the crushing bin 4. The second crushing roller 305 can rotate on the inner wall of the crushing bin 4. Through the provided crushing assembly 3, the first crushing roller 302 and the second crushing roller 305 make relative movement, so that the crushing blocks on the outer surfaces of the first crushing roller 302 and the second crushing roller 305 crush the quartz sand, thereby breaking up the lumps in the quartz sand, avoiding the lumps in the added quartz sand affecting the subsequent use, thereby greatly increasing the practicality of the device.

[0026] The inner top wall of the aggregate bin 1 is fixedly connected with the crushing bin 4, and the inner wall of the aggregate bin 1 is slidably connected with the sieve plate 7. The outer surface of the sieve plate 7 and the inner wall of the aggregate bin 1 should be set to be relatively smooth so that the sieve plate 7 can slide up and down on the inner wall of the aggregate bin 1 to facilitate the screening of quartz sand.

[0027] Two vibration components 8 are arranged on the outside of the screen plate 7, and the vibration component 8 includes a support plate 801 and a moving rod 805. The side of the support plate 801 close to the inner wall of the aggregate bin 1 is fixedly connected to the inner wall of the aggregate bin 1, and the upper surface of the support plate 801 is fixedly connected with a sleeve 802, and the inner bottom wall of the sleeve 802 is fixedly connected with a spring 803, and the end of the spring 803 away from the inner bottom wall of the sleeve 802 is fixedly connected with a spring damper 804. The spring damper 804 can reduce the force of the moving rod 805 during movement to avoid damage to the rigid structure.

[0028] The upper surface of the spring damper 804 is fixedly connected to the bottom surface of the moving rod 805, and the outer surface of the spring damper 804 and the outer surface of the moving rod 805 are both slidably connected to the inner wall of the sleeve 802. The moving rod 805 and the sleeve 802 are both made of stainless steel with relatively smooth surfaces, so that the moving rod 805 can slide up and down on the inner wall of the sleeve 802.

[0029] The upper surface of the moving rod 805 is fixedly connected to the bottom surface of the sieve plate 7. Through the vibration component 8, the spring 803 can be compressed when the sieve plate 7 moves downward. When the sieve plate 7 stops moving, it will rebound immediately, driving the sieve plate 7 to move upward, thereby achieving the vibration effect of the sieve plate 7. The quartz sand can be screened to prevent impurities from being used with the quartz sand and preventing it from affecting subsequent processing.

[0030] The bottom surface of the aggregate bin 1 is fixedly connected to a distribution bin 5, and the bottom surface of the distribution bin 5 is fixedly connected to a group of discharge pipes 6. Through the cooperation between the distribution bin 5 and the discharge pipes 6, the quartz sand can be discharged evenly. The outer surface of the aggregate bin 1 is fixedly connected to a collecting box 14, and a through hole is opened on the left side of the aggregate bin 1, through which the impurities remaining on the surface of the sieve plate 7 can be discharged into the interior of the collecting box 14, so as to facilitate the subsequent treatment of the impurities.

[0031] A second motor 9 is fixedly installed on the outer surface of the aggregate bin 1, and a rotating rod 10 is fixedly connected to the output end of the second motor 9. The end of the rotating rod 10 away from the second motor 9 passes through the outer surface of the aggregate bin 1 and is rotatably connected to the inner wall of the aggregate bin 1. Two cams 11 are fixedly connected to the outer surface of the rotating rod 10. The cams 11 are arranged to move the sieve plate 7 so that the sieve plate 7 vibrates, which is convenient for the subsequent screening of quartz sand.

[0032] A third motor 13 is fixedly installed on the left and right sides of the distribution bin 5, and the output ends of the two third motors 13 are fixedly connected to the auger rod 12. The ends of the two auger rods 12 away from the third motors 13 are rotatably connected to the inner wall of the distribution bin 5. The auger rod 12 can drive the quartz sand to move after the quartz sand enters the distribution bin 5, so that the quartz sand is evenly distributed inside the distribution bin 5, which is convenient for the subsequent uniform addition of quartz sand.

[0033] Working principle: When it is necessary to evenly add photovoltaic high-purity quartz sand, first pour the quartz sand into the interior of the collecting bin 1 through the feeding trough 2, start the first motor 301 to drive the first crushing roller 302 to rotate, and when the first crushing roller 302 rotates, it will drive the first gear 303 to rotate. By utilizing the meshing relationship between the first gear 303 and the second gear 304, the first gear 303 can drive the second gear 304 to rotate when it rotates, thereby driving the second crushing roller 305 to rotate, so that the first crushing roller 302 and the second crushing roller 305 can make relative motion, so as to break up the lumps of quartz sand entering the crushing bin 4, and facilitate the subsequent use of quartz sand. The crushed quartz sand will fall to the upper surface of the sieve plate 7. Starting the second motor 9 can drive the cam 11 to rotate and hit the sieve plate 7. After being hit, the sieve plate 7 will move downward and drive the spring 803 to be compressed. After stopping the hitting, it will immediately rebound and drive the sieve plate 7 to rise, thus achieving the vibration effect of the sieve plate 7 to screen the quartz sand, and can ensure that the added quartz sand does not contain lumps and impurities, which is beneficial to subsequent processing.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
