[0023] Specifically, the conveying belt 702 rotates around the two conveying rollers 701 (the conveying belt 702 rotates along the direction of the arrow A1) Figure 1When the apple passes through the bottom of the second sorting camera 301, the sorting camera 301 can collect the volume size information of the apple, if the volume of the apple is small, the servo reduction motor 202 corresponding to the sorting camera 301 is started, the output shaft of the servo reduction motor 202 drives the rotating disc 203 to rotate one circle, the rotating disc 203 drives the sliding block 2010 and the positioning pin 2011 to rotate together through the straight groove 209, and drives the dragging plate 205, the upper and lower light shafts 206 and the push plate 207 to move along the sliding connection direction of the light shaft 206 and the fixed plate 208 to the direction close to the aluminum profile conveying frame 100 under the connection action of the connecting rod 204, the apple with small volume on the top of the conveying belt 702 is pushed into the corresponding guide tile groove 600 through the movement of the push plate 207, and finally falls into the collection frame at the bottom of the guide tile groove 600 for unified collection, while the apple with large volume is directly conveyed to the bottom of the next sorting camera 301 by the conveying belt 702, and so on, so as to realize the screening of the volume size information of the apple. When the apple passes through the bottom of the second sorting camera 301, the sorting camera 301 can collect the volume size information of the apple, if the volume of the apple is small, the servo reduction motor 202 corresponding to the sorting camera 301 is started, the output shaft of the servo reduction motor 202 drives the rotating disc 203 to rotate one circle, the rotating disc 203 drives the sliding block 2010 and the positioning pin 2011 to rotate together through the straight groove 209, and drives the dragging plate 205, the upper and lower light shafts 206 and the push plate 207 to move along the sliding connection direction of the light shaft 206 and the fixed plate 208 to the direction close to the aluminum profile conveying frame 100 under the connection action of the connecting rod 204, the apple with small volume on the top of the conveying belt 702 is pushed into the corresponding guide tile groove 600 through the movement of the push plate 207, and finally falls into the collection frame at the bottom of the guide tile groove 600 for unified collection, while the apple with large volume is directly conveyed to the bottom of the next sorting camera 301 by the conveying belt 702, and so on, so as to realize the screening of the volume size information of the apple.

[0024] Further, with reference to Figure 7 and Figure 8 illustrated: The sorting unit 200 further comprises an anti-collision assembly, which comprises a straight slot 209, a sliding block 2010, a positioning pin 2011, a dynamic magnetic block 2012, a static magnetic block 2013 and a spring 2014. The straight slot 209 is formed through the top of the rotating disc 203. The sliding block 2010 is slidingly installed in the straight slot 209 and extends to the top and bottom of the rotating disc 203. The positioning pin 2011 is fixedly installed on the top of the sliding block 2010. The connecting rod 204 is hinged to the sliding block 2010 through the positioning pin 2011. The spring 2014 is fixedly arranged in the straight slot 209 and is fixedly installed between one end of the sliding block 2010 close to the center of the rotating disc 203 and the inner wall of one side of the straight slot 209 close to the center of the rotating disc 203. The dynamic magnetic block 2012 is fixedly installed on the bottom of the sliding block 2010. The static magnetic block 2013 is fixedly installed on the top of the horizontal mounting plate 201 and is close to the center of the rotating disc 203. The magnetic property of the static magnetic block 2013 is opposite to that of the dynamic magnetic block 2012.

[0025] Specifically, in the process of the servo deceleration motor 202 output shaft driving the rotating disc 203 to rotate, initially, due to the elastic force of the spring 2014, the push block 2010 is located at one end of the straight groove 209 away from the center of the rotating disc 203, at this time, the sliding block 2010 and the positioning pin 2011 rotate with the rotating disc 203 at the maximum radius, so the connecting action of the connecting rod 204 drives the dragging plate 205, the optical shaft 206 and the push plate 207 to move at the fastest speed, and in the process of the sliding block 2010 rotating with the rotating disc 203, the moving magnetic block 2012 at the bottom of the sliding block 2010 rotates together, when the push plate 207 is about to contact the apple on the top of the conveying belt 702, the moving magnetic block 2012 just rotates to the periphery of the static magnetic block 2013 with the sliding block 2010, therefore, under the magnetic attraction of the static magnetic block 2013 to the moving magnetic block 2012, the sliding block 2010 slides along the inner wall of the straight groove 209 towards the center of the rotating disc 203, so that the spring 2014 is compressed to accumulate elastic force, at the same time, the sliding block 2010 drives the positioning pin 2011 to move, so that the positioning pin 2011 rotates with the rotating disc 203 at a smaller radius, so the connecting rod 204 drives the dragging plate 205, the optical shaft 206 and the push plate 207 to move at a slower speed, so as to slow down the contact speed of the push plate 207 and the apple on the top of the conveying belt 702, so as to avoid bruising the apple, and after the push plate 207 contacts the apple, as the rotating disc 203 continues to rotate, the moving magnetic block 2012 rotates from the periphery of the static magnetic block 2013 to be misaligned, the magnetic attraction of the moving magnetic block 2012 disappears, then the sliding block 2010, the positioning pin 2011 and the moving magnetic block 2012 are pushed to slide reversely along the inner wall of the straight groove 209 under the elastic force of the spring 2014, after that, the positioning pin 2011 rotates with the rotating disc 203 at the maximum radius, so the speed of the push plate 207 increases, the apple on the conveying belt 702 is quickly pushed into the guide tile groove 600, and finally falls into the collection frame at the bottom of the guide tile groove 600 under the action of gravity, so as to avoid bruising the apple while further improving the movement efficiency of the push plate 207, thereby improving the sorting speed of the apple and the sorting capacity of the apple.

[0026] Further, with reference to Figure 2 One end of the side surface of the aluminum profile transmission frame 100 is fixedly installed with a driving motor 500 through a fixing seat, a driving synchronous wheel 501 is fixedly installed on the output shaft of the driving motor 500, and a driven synchronous wheel 502 is fixedly installed at one end of one conveying roller 701 close to the driving synchronous wheel 501. The driven synchronous wheel 502 and the periphery of the driving synchronous wheel 501 are jointly sleeved with a synchronous belt 503.

[0027] ​Specifically, the output shaft of the drive motor 500 drives the active synchronous pulley 501 to rotate. The rotation of the active synchronous pulley 501 drives the driven synchronous pulley 502 and a conveyor roller 701 connected to the driven synchronous pulley 502 to rotate through the synchronous belt 503, thereby driving the conveyor belt 702 to rotate around the two conveyor rollers 701 to realize the transfer of apples.

[0028] In operation, the present invention drives the active synchronous pulley 501 to rotate via the output shaft of the drive motor 500. The rotation of the active synchronous pulley 501 drives the driven synchronous pulley 502 and a conveyor roller 701 connected to the driven synchronous pulley 502 to rotate via the synchronous belt 503. This, in turn, drives the conveyor belt 702 to rotate around the two conveyor rollers 701. Figure 1 (The conveyor belt 702 operates in the L direction) and transports apples to be sorted. Because anti-roll barriers 703 are evenly spaced on the surface of the conveyor belt 702, the apples can be prevented from rolling laterally during the transport process. Furthermore, due to the limiting effect of the anti-roll sheet metal 400 symmetrically arranged on the top of the conveyor belt 702, the apples on the top of the conveyor belt 702 can be prevented from rolling longitudinally, ensuring that the apples can be transported by the conveyor belt 702 to the other end of the aluminum profile transmission frame 100. During the process of apples being conveyed by conveyor belt 702, multiple sorting cameras 301 continuously collect the appearance, size, and color of the apples. When an apple passes the first set of sorting cameras 301, the sorting camera 301 can identify the apple's color. If the apple's color is bluish, a servo reduction motor 202 corresponding to that sorting camera 301 is activated. Its output shaft drives the turntable 203 to rotate one revolution. The turntable 203 drives the slider 2010 and positioning pin 2011 to rotate together through the straight groove 209, and under the connection of the connecting rod 204, it drives the drag plate 2. 05. The upper and lower optical axes 206 and the push plate 207 move towards the aluminum profile transmission frame 100 along the sliding connection direction between the optical axis 206 and the fixed plate 208. The movement of the push plate 207 pushes the green apples located at the top of the conveyor belt 702 into a guide trough 600 corresponding to the position of the sorting camera 301. Finally, the apples fall into the collection box at the bottom of the guide trough 600 and are collected uniformly. The red apples are directly transported by the conveyor belt 702 to the bottom of the next sorting camera 301 through the bottom of the sorting camera 301. When an apple passes the bottom of the second sorting camera 301, the sorting camera 301 can collect the apple's size information. If the apple is too small, a servo reduction motor 202 corresponding to the sorting camera 301 is activated, and its output shaft drives the turntable 203 to rotate one revolution. The turntable 203 drives the slider 2010 and the positioning pin 2011 to rotate together through the straight groove 209. Under the connection of the connecting rod 204, it drives the drag plate 205, the upper and lower optical axes 206 and the push plate 207 to move along the optical axis 206 and the fixed plate 208. The sliding connection moves towards the aluminum profile transmission frame 100. The push plate 207 moves to push the smaller apples on the top of the conveyor belt 702 into a guide trough 600 corresponding to the position of the sorting camera 301. The apples fall into the collection box at the bottom of the guide trough 600 and are collected uniformly. The larger apples are directly transported by the conveyor belt 702 to the bottom of the next sorting camera 301 through the bottom of the sorting camera 301, and so on, so as to achieve the sorting of apples by size. During the rotation of the turntable 203 driven by the output shaft of the servo geared motor 202, initially, due to the elastic force of the spring 2014, the pusher slider 2010 is located at the end of the straight groove 209 furthest from the center of the turntable 203. At this time, the slider 2010 and the positioning pin 2011 have the largest radius of rotation with the turntable 203. Therefore, the drag plate 205, the optical shaft 206, and the push plate 207 move at the fastest speed through the connecting action of the connecting rod 204. During the rotation of the turntable 203, the slider 2010 drives the moving magnet 201 located at its bottom. 2. As they rotate together, when the push plate 207 is about to contact the apple located at the top of the conveyor belt 702, the moving magnetic block 2012 rotates with the slider 2010 to the periphery of the stationary magnetic block 2013. Since the stationary magnetic block 2013 and the moving magnetic block 2012 have opposite magnetic properties, under the magnetic attraction of the stationary magnetic block 2013 on the moving magnetic block 2012, the slider 2010 slides along the inner wall of the straight groove 209 towards the center of the turntable 203, thereby compressing and storing the elastic force of the spring 2014. At the same time, the slider 2010 drives the positioning pin 2011 to move, causing the positioning pin 2011 to move. As the radius of the pivot pin 2011 decreases with the rotation of the turntable 203, the speed at which the drag plate 205, the optical shaft 206, and the push plate 207 move via the connecting rod 204 slows down. This reduces the contact speed between the push plate 207 and the apples on the top of the conveyor belt 702, preventing the apples from being crushed. After the push plate 207 contacts the apples, as the turntable 203 continues to rotate, the moving magnetic block 2012 rotates from the periphery of the stationary magnetic block 2013 to a misalignment. The magnetic attraction force on the moving magnetic block 2012 disappears, and then, under the action of the spring 2014's rebound force, the push plate 2012... The movable slider 2010, positioning pin 2011, and movable magnetic block 2012 slide back to their original positions along the inner wall of the straight groove 209. Then, the positioning pin 2011 returns to its maximum radius as the turntable 203 rotates, thus accelerating the movement of the push plate 207. This quickly pushes the apples on the conveyor belt 702 into the guide trough 600, where they finally fall into the collection frame at the bottom of the guide trough 600 under gravity. This not only avoids crushing the apples but also further improves the movement efficiency of the push plate 207, thereby increasing the apple sorting speed and improving the apple sorting capacity.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
