Example 2:

a color selector, which comprises the bad fruit removing device for the fruits like apples in embodiment 1.

The use principle of the invention is as follows: specifically, the apple-like fruits are conveyed to a distributor 11 which is rotatably arranged through a conveying belt, the open slot 111 singly and orderly conveys the apple-like fruits in the rotating process of the distributor 11, in the process, when the image recognition device 31 does not monitor the apple-like fruits, a telescopic rod 1343 is kept in a non-contact state with a second limiting column 1342, at the moment, in the continuous rotating process of the distributor 11, a material driving rod 131 props against the apple-like fruits through the action of a spring 133, so that the apple-like fruits are pushed to extrude a limiting plate 112 into a material conveying mechanism 14, when the image recognition device 31 monitors the apple-like fruits, the material driving rod 131 drives the limiting rod 132 to move under the extrusion of the end part of the open slot 111, a barb part of the limiting rod 132 is inserted between the first limiting column 1341 and the second limiting column 1342, at the moment, the telescopic rod 1343 is driven, so that a fastening device 134 clamps the limiting rod 132, so that the material driving rod 131 swings into the material blocking plate 111, when the baffle plate 111 rotates to the I12, the elastic end of the apple-like fruits is removed through the open slot 111;

specifically, the apple-like fruits enter the accommodating cavity 141, at this time, the limiting plate 112 is restored to the vertical state through the coil spring 113, when the apple-like fruits enter the bottom of the accommodating cavity 141, the accommodating cavity 141 slides up and down elastically, so that the apple-like fruits are buffered and protected, the apple-like fruits enter the fruit receiving device 15 through the conveying pipeline 142, the apple-like fruits reach the first buffering net 151 first by virtue of inertia, the first buffering net 151 decelerates and buffers the apple-like fruits, due to the action of the counterweight column 153, the first buffering net 151 inclines downwards, so that the apple-like fruits move downwards to the second buffering net 152 and pass through the second buffering net 152 to enter the placing groove 22, and therefore the apple-like fruits are buffered and cleared of surface impurities through the second buffering net 152, and the accuracy of the image recognition device 31 is prevented from being affected, wherein the counterweight column 153 is made of stainless steel and is horizontally arranged;

specifically, when the fruits such as apples enter the placing groove 22, the annular conveying belt 21 drives the placing groove 22 to move, in the process, when the placing groove 22 moves to the upper end of the first toothed plate 26, the first toothed plate 26 is meshed with the first driving shaft 231, at the moment, the first driving shaft 231 rotates to drive the driven shafts i 232 and ii 233 to synchronously and simultaneously rotate through the driving belt 234, so that the positions of the fruits such as apples contacting with the upper end surfaces of the driven shafts i 232 and ii 233 are adjusted, so that the fruits such as apples are subjected to multi-angle identification by matching with the image identification device 31, when the placing groove 22 moves to the upper end of the second toothed plate 27, if the image identification device 31 does not monitor bad fruits such as apples, at the moment, the second toothed plate 27 is meshed with the third driving shaft 244, the third driving shaft 244 rotates to drive the driving toothed plate 245 to horizontally move towards the direction of the second driving shaft 241, and further drives the second driving shaft 241 to rotate, so that the placing trough 22 rotates with the second driving shaft 241 as an axis, the lower end surface of the end of the second driving shaft 241 is in a shape of a tooth, and thus, the second driving shaft 241 only rotates by a certain angle, the specific rotating angle depends on the tooth structure area set up in practical situations, when the third driving shaft 244 is separated from the second toothed plate 27, the third driving shaft 244 is in a free rotating state, at this time, the counterweight shaft 242 moves downwards by virtue of its own gravity, and further drives the second driving shaft 241 to rotate in reverse direction, so that the placing trough 22 is reset, and the transmission toothed plate 245 is reset, so that in the process that the placing trough 22 tilts upwards, fruits such as apples enter the fruit collecting conveyor belt 246 through the placing trough 22 and then enter the fruit collecting cavity to be collected, wherein, according to practical requirements, the rotating angle of the third driving shaft 244 can be controlled by changing the length of the second toothed plate 27, thereby controlling the distance that the driving toothed plate 245 moves;

specifically, when the placing groove 22 moves to the upper end of the second toothed plate 27, if the image recognition device 31 monitors that the fruits such as apples are damaged, at this time, the smooth top plate 28 is ejected upwards, so that the third driving shaft 244 moves upwards in the connecting frame 29, and further the placing groove 22 is driven to move upwards, so that the damaged fruits such as apples are removed by matching with the material blocking plate ii 233, wherein the length of the smooth top plate 28 is set according to actual requirements, and therefore, in the rotating process of the annular conveying belt 21, the third driving shaft 244 can slide on the smooth top plate 28 for a certain distance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
