An opening is provided on the side wall of the lower fruit receiving basin 2 at the position corresponding to the lower end of the bottom of the basin. The opening is connected to the transition groove 20 and forms a discharge port. A support rod 13 is also connected between the upper fruit receiving basin 1 and the lower fruit receiving basin 2.

[0037] The working principle of this utility model is as follows:

[0038] like Figures 1 to 2 As shown, before use, a lower fruit receiving basin 2 is fixedly installed on the picking vehicle, and an upper fruit receiving basin 1 is connected and fixed above the lower fruit receiving basin 2 by a support rod 13. The bottom of the upper fruit receiving basin 1 is provided with an arc-shaped first discharge groove 11 and a second discharge groove 12 parallel to the circumference of the bottom of the upper fruit receiving basin 1.

[0039] like Figures 3 to 6As shown, a power motor 21 is arranged at the lower end of the lower fruit receiving basin 2, a transmission shaft 22 is connected to the output end of the power motor 21, the transmission shaft 22 vertically upwards is sequentially arranged out of the lower fruit receiving basin 2 and the upper fruit receiving basin 1, and an agitating plate 23 horizontally extends at the position where the transmission shaft 22 is arranged out of the upper fruit receiving basin 1; wherein bearings 24 are arranged at the positions where the transmission shaft 22 is arranged out of the two fruit receiving basins, the two ends of the transmission shaft 22 are sleeved in the middle part of the corresponding bearing 24, and fixed sleeves 25 are sleeved at the positions between the transmission shaft 22 and the two fruit receiving basins, the upper and lower ends of the fixed sleeves 25 are respectively connected and fixed with the upper fruit receiving basin 1 and the lower fruit receiving basin 2, and the middle part of the upper fruit receiving basin 1 and the lower fruit receiving basin 2 is sleeved outside the corresponding bearing 24.

[0040] Then, a first rail frame 31 and a second rail frame 32 are arranged between the lower fruit receiving basin 2 and the upper fruit receiving basin 1 and are fixedly connected by an upper connecting plate 30 and a lower connecting plate 33, the two rail frames are arranged side by side in a spiral manner from top to bottom, four material receiving hoppers 26 are arranged below the two rail frames and are connected with the fixed sleeves 25 and are sequentially arranged from top to bottom along the spiral direction of the two rail frames (as shown in Figure 1 and Figure 6 As shown), the four material receiving hoppers 26 are respectively provided with a camera 27 and a discharge hole, the discharge hole is provided with an electric door mechanism and is in communication with the lower fruit receiving basin 2.

[0041] The bottom of the lower fruit receiving basin 2 is provided with a slope structure, a transition groove 20 is arranged at the low end of the bottom, and an opening is arranged on the side wall of the lower fruit receiving basin 2 corresponding to the position of the low end of the bottom and is in communication with the transition groove 20.

[0042] In use, the picked fruits are transported into the upper fruit receiving basin 1, the power motor 21 is started by the controller, the transmission shaft 22 and the agitating plate 23 are synchronously rotated by the output end of the power motor 21, the fruits in the upper fruit receiving basin 1 are moved in the upper fruit receiving basin 1, and the single fruits are dropped out of the upper fruit receiving basin 1 from the first discharge slot 11 or the second discharge slot 12, and the dropped fruits are correspondingly dropped onto the first rail frame 31 or the second rail frame 32, since the fence 34 is vertically arranged at the position between the upper end edge of the first rail frame 31 and the second rail frame 32 and the lower end surface of the upper connecting plate 30, the position where the fruits drop out of the upper fruit receiving basin 1 will not fall outside the rail frame position, and the single fruits can smoothly flow along the rail frame direction.

[0043] Since the track spacing of the first track frame 31 and the second track frame 32 is arranged in an increasing pattern from top to bottom, combined with the arrangement of the four receiving hoppers 26, that is, at the position of each receiving hopper 26, the track spacing of the two track frames is increased, taking the fruit diameter range of 50-80 mm as an example, the fruit diameter range is divided into four segments, 50-60 mm, 60-70 mm, 70-75 mm, and 75-80 mm, and the track spacing of the track frame is correspondingly matched and set. Thus, the uppermost receiving hopper 26 collects fruits with a diameter of 50-60 mm, the next receiving hopper 26 collects fruits with a diameter of 60-70 mm, the next receiving hopper 26 collects fruits with a diameter of 70-75 mm, and the lowermost receiving hopper 26 collects fruits with a diameter of 75-80 mm.

[0044] Meanwhile, a camera 27 connected to the controller is arranged on the inner wall of each receiving hopper 26. Before use, the image of the fruit pile or the preset image conversion data is input into the controller in advance. When the fruit reaches the hopper opening position of the receiving hopper 26, the camera 27 compares the real-time photographic image with the preset image or data, and accordingly starts the electric door mechanism at the corresponding position of the receiving hopper 26 to release the fruits with the corresponding diameter. The fallen fruits quickly roll down to the transition groove 20 on the inclined bottom of the lower fruit bowl 2 and are removed from the opening of the lower fruit bowl 2 by inertia. Since the operator is familiar with the corresponding fruit specifications in each receiving hopper 26, the removed fruits can be accurately classified, packaged, and placed.

[0045] It should be noted that since each receiving hopper 26 is not far apart, in order to avoid other specifications of fruits falling into the opened receiving hopper 26 when the electric door mechanism is opened, the critical position when the receiving hopper 26 is full should not be selected in the pre-input image or the related parameters, and the hopper opening position should be selected to ensure the space for multiple fruits and prevent the occurrence of mixed loading. Similarly, when two or more receiving hoppers 26 meet the full load judgment of the controller, the electric door mechanism of the corresponding receiving hopper 26 should be opened in sequence according to the set discharge logic relationship to achieve the purpose of orderly discharging and collecting.

[0046] In the foregoing, the opening and closing action of the electric door mechanism is as follows: Figure 8 As shown in FIGS. a and b of the drawings, in the direction from FIG. b to FIG. a, the camera 27 compares the real-time photographic image with the preset image or data, and the controller judges that the conditions for full loading and opening are met, and simultaneously sends an opening instruction to the first stepper motor 41 and the second stepper motor 42, and drives the first branch rod 51 to rotate in the clockwise direction (as shown in FIG. a) through the output end of the first stepper motor 41. Figure 8and the output end of the second stepping motor 42 drives the fifth support rod 55 to rotate in the clockwise direction, and the coaxially hinged second support rod 52 is synchronously moved, and the first shutter 43 hinged to the second support rod 52 is moved to the outside of the discharge hole, and the fifth support rod 55 drives the coaxially hinged sixth support rod 56 to synchronously move, and the second shutter 44 hinged to the sixth support rod 56 is moved to the outside of the discharge hole, and the two shutters are moved to the outside to form an open door shape and expose the discharge hole (as shown in Figure 7 The fruit in the receiving hopper 26 falls into the lower receiving fruit basin 2 through the discharge hole.

[0047] The controller is preset with an opening time to maintain an open state for a period of time, and when the preset time is reached, the controller sends a closing instruction to the two stepping motors, as shown in Figure 7 and Figure 8 In the order of a figure to a figure, the output end of the first stepping motor 41 drives the first support rod 51 to rotate in the counterclockwise direction (in the direction shown in Figure 8 and the output end of the second stepping motor 42 drives the fifth support rod 55 to rotate in the clockwise direction, and the coaxially hinged second support rod 52 is synchronously moved, and the first shutter 43 hinged to the second support rod 52 is moved to the outside of the discharge hole, and the fifth support rod 55 drives the coaxially hinged sixth support rod 56 to synchronously move, and the second shutter 44 hinged to the sixth support rod 56 is moved to the outside of the discharge hole, and the two shutters are moved to the outside to form an open door shape and expose the discharge hole (as shown in

[0048] In order to ensure the stability of the movement of the two shutters, a second connecting pin 46 is arranged at the lower end of the first shutter 43, the second connecting pin 46 is hinged to one side of the third support rod 53, the other side of the third support rod 53 is coaxially hinged to one side of the fourth support rod 54, and the other side of the fourth support rod 54 is hinged to the support frame 4; Similarly, a fourth connecting pin 48 is arranged at the lower end of the second shutter 44, the fourth connecting pin 48 is hinged to one side of the seventh support rod 57, the other side of the seventh support rod 57 is coaxially hinged to one side of the eighth support rod 58, and the other side of the eighth support rod 58 is hinged to the support frame 4; Two same transmission connection structures are arranged on each shutter, which not only can support the shutter to prevent fruit from leaking out, but also can ensure the stability of the movement in the opening and closing process.

[0049] According to the foregoing, the picked fruit is directly sent into the upper receiving fruit basin 1, and is transferred through the two rail frames and falls into the corresponding receiving hopper 26, and sequentially falls into the lower receiving fruit basin 2 in order and realizes rapid classification and packaging, the whole process is fast, the movement difference of each link is not large, and the fruit is not easily damaged, the good fruit rate is improved, the fruit is classified and packaged immediately after picking, and the transportation cost is reduced; In order to better reduce the damage in the transfer process, the discharge holes of the three receiving hoppers 26 at the upper end are vertically downward, and the discharge hole of the receiving hopper 26 at the lowest end is horizontally outward.
