Example 2:

A color sorter, comprising the device for removing bad apple-like fruits described in Embodiment 1.

The principle of use of the present invention: Specifically, the apple-like fruits are transported to the rotating distributing device 11 through the conveyor belt, and the opening groove 111 carries out single and orderly conveying of the apple-like fruits during the rotation of the distributing device 11 , during this process, when the image recognition device 31 does not detect any bad apple-like fruit, the telescopic rod 1343 remains in a non-contact state with the second limit post 1342. At this time, during the continuous rotation of the distributor 11, The driving rod 131 touches the apple-like fruit through the action of the spring 133, and then pushes the apple-like fruit to squeeze the limit plate 112 and enters the feeding mechanism 14. When the image recognition device 31 detects that the apple-like fruit is bad At this time, the driving rod 131 drives the stop rod 132 to move under the extrusion of the end of the opening groove 111, and the barbed part of the stop rod 132 is inserted between the first stop post 1341 and the second stop post 1342. At this time, the telescopic rod 1343 is driven, so that the fastening device 134 blocks the limit rod 132, thereby restricting the driving rod 131 from swinging into the opening groove 111. Go deep into the elastic end in the opening groove 111 to remove bad apple-like fruits;

Specifically, the apple-like fruit enters the accommodating cavity 141. At this time, the limit plate 112 returns to the vertical state through the coil spring 113. When the apple-like fruit enters the bottom of the accommodating cavity 141, the accommodating cavity 141 Elastically slide up and down, so as to buffer and protect the apple-like fruit. The apple-like fruit enters the fruit receiving device 15 through the conveying pipeline 142. With the help of inertia, the apple-like fruit first arrives on the first buffer net 151, and the second A buffer net 151 decelerates and buffers the apple-like fruit. Due to the effect of the counterweight column 153, the first buffer net 151 is inclined downward, so that the apple-like fruit moves downward to the second buffer net 152 and passes through the second buffer net 152. The second buffer net 152 enters into the placement tank 22, so that the second buffer net 152 can buffer the apple-like fruits and remove surface debris, so as to avoid affecting the accuracy of the image recognition device 31, wherein the counterweight column 153 Made of stainless steel and set horizontally;

Specifically, when the apple-like fruit enters into the placement groove 22, the endless conveyor belt 21 drives the placement groove 22 to move. In the process, when the placement groove 22 moves to the upper end of the first tooth plate 26, the first tooth plate 26 Mesh with the first drive shaft 231, at this time the first drive shaft 231 rotates and then drives the driven shaft I 232 and the driven shaft II 233 to rotate synchronously and in the same direction through the transmission belt 234, so as to adjust the drive shaft I 232 and the driven shaft The position of the apple-like fruit that is in contact with the upper end surface of II 233, so as to cooperate with the image recognition device 31 to carry out multi-angle recognition of the apple-like fruit. When the placement groove 22 moves to the upper end of the second tooth plate 27, if the image recognition device 31 No bad fruit of class apple fruit is detected. At this moment, the second gear plate 27 is engaged with the third drive shaft 244, and the third drive shaft 244 rotates to drive the drive gear plate 245 to move horizontally to the second drive shaft 241, thereby driving The second driving shaft 241 rotates, and then, the placement groove 22 is rotated with the second driving shaft 241 as the axis, and the lower end surface of the end of the second driving shaft 241 is a tooth shape, thus, the second driving shaft 241 only rotates for a certain amount of time. Angle, the specific rotation angle size depends on the area of the tooth structure set according to the actual situation. When the third drive shaft 244 was separated from the second tooth plate 27, the third drive shaft 244 was in a free rotation state. Gravity moves downwards, and then drives the second drive shaft 241 to reversely rotate, so that the placement groove 22 is reset, and the transmission tooth plate 245 is reset, thus, in the process of the placement groove 22 tilting upward, the apple-like fruits pass through the placement groove. 22 into the fruit collection conveyor belt 246, and then into the fruit collection cavity 247 to collect, wherein, according to actual needs, the angle of rotation of the third drive shaft 244 can be controlled by changing the length of the second tooth plate 27, and then control the transmission The distance that the tooth plate 245 moves;

Specifically, when the placement groove 22 moves to the upper end of the second toothed plate 27, if the image recognition device 31 detects a bad apple-like fruit, at this moment, the smooth top plate 28 is pushed out upwards, so that the third drive shaft 244 is in the The connecting frame 29 moves upwards, and then drives the placement groove 22 to move upwards, so as to cooperate with the baffle plate II 233 to remove bad apple-like fruits. Among them, the length of the smooth top plate 28 is set according to actual needs, so that, on the endless conveyor belt During the rotation of 21, the third drive shaft 244 can slide a certain distance on the smooth top plate 28.

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