[0037] The bottom of the lower fruit receiving basin 2 is arranged as an inclined structure, and a transition groove 20 is arranged at the lower end of the bottom of the basin. An opening is arranged on the side wall of the lower fruit receiving basin 2 at a position corresponding to the lower end of the bottom of the basin, and the opening is connected with the transition groove 20 to form a discharge port; a support rod 13 is also connected between the upper fruit receiving basin 1 and the lower fruit receiving basin 2.

[0038] The use principle of the present invention is as follows:

[0039] like Figure 1 to Figure 2 As shown, before use, a lower fruit receiving basin 2 is fixed 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, and a first arc-shaped discharge trough 11 and a second discharge trough 12 are arranged at the bottom of the upper fruit receiving basin 1 in parallel along the circumferential direction of the bottom of the upper fruit receiving basin 1.

[0040] like Figures 3 to 6As shown, a power motor 21 is arranged at the lower end of the lower fruit basin 2, and a transmission shaft 22 is connected to the output end of the power motor 21, and the transmission shaft 22 vertically and upwardly penetrates the lower fruit basin 2 and the upper fruit basin 1 in sequence, and a horizontally extending stirring plate 23 is arranged at the position where the transmission shaft 22 penetrates the upper fruit basin 1; wherein, bearings 24 are arranged at the penetration position between the transmission shaft 22 and the two fruit basins, and both ends of the transmission shaft 22 are sleeved on the middle part of the bearing 24 at the corresponding end, and a fixing sleeve 25 is sleeved on the outer side of the transmission shaft 22 at the position corresponding to the position between the two fruit basins, and the upper and lower ends of the fixing sleeve 25 are respectively connected and fixed to the upper fruit basin 1 and the lower fruit basin 2, and the middle parts of the upper fruit basin 1 and the lower fruit basin 2 are sleeved on the outer side of the bearing 24 at the corresponding end.

[0041] Then, a first rail frame 31 and a second rail frame 32 are provided between the lower fruit receiving basin 2 and the upper fruit receiving basin 1, which 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 receiving hoppers 26 (such as hoppers 26) connected to the fixing sleeve 25 and arranged continuously from top to bottom along the spiral direction of the two rail frames are provided below the two rail frames. Figure 1 and Figure 6 As shown), the four receiving hoppers 26 are each provided with a camera 27 and a discharging hole, and the discharging hole is each provided with an electric door mechanism and is connected to the lower fruit receiving basin 2.

[0042] The bottom of the lower fruit receiving basin 2 is an inclined structure, a transition groove 20 is provided at the lower end of the basin bottom, and an opening communicating with the transition groove 20 is provided on the side wall of the lower fruit receiving basin 2 at a position corresponding to the lower end of the basin bottom.

[0043] When in use, the picked fruits are transported to the upper fruit receiving basin 1, and the power motor 21 is started by the controller. The output end of the power motor 21 drives the transmission shaft 22 and the stirring plate 23 to rotate synchronously, so that the fruits in the upper fruit receiving basin 1 are moved in the upper fruit receiving basin 1, and a single fruit is dropped out of the upper fruit receiving basin 1 from the first discharge trough 11 or the second discharge trough 12, and the dropped fruits fall onto the first rail frame 31 or the second rail frame 32 accordingly. Since a fence 34 is vertically provided at a 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 fruit falls out of the upper fruit receiving basin 1 will not fall outside the rail frame position, thereby ensuring that the single fruit can flow smoothly along the rail frame direction.

[0044] Since the track spacing of the first rail frame 31 and the second rail frame 32 are set in an increasing manner from top to bottom, combined with the setting of the four receiving hoppers 26, that is, at the position of each receiving hopper 26, the track spacing of the two rail frames must be increased, taking the fruit diameter range of 50-80mm as an example, it is first divided into four fruit diameter sections, 50mm-60mm as one section, 60mm-70mm as one section, 70mm-75mm as one section, and 75mm-80mm as one section, and the track spacing of the rail frames is adapted accordingly. Thus, the receiving hopper 26 at the uppermost end collects fruits with a fruit diameter of 50mm-60mm, the receiving hopper 26 adjacent to the lower end collects fruits with a fruit diameter of 60mm-70mm, the receiving hopper 26 adjacent to the lower end collects fruits with a fruit diameter of 70mm-75mm, and the receiving hopper 26 at the lowest end collects fruits with a fruit diameter of 75mm-80mm.

[0045] At the same time, a camera 27 connected to the controller is provided on the inner wall of each receiving hopper 26. Before use, an image of the fruit stacking state or data converted from a preset image is pre-input into the controller. During use, when the fruit reaches the mouth of the receiving hopper 26, the camera 27 compares the real-time photographic image with the preset image or data, and thereby starts the electric door mechanism corresponding to the position of the receiving hopper 26 to release the fruit of the corresponding fruit diameter. The fallen fruit quickly rolls down into the transition groove 20 at the inclined bottom of the lower fruit receiving basin 2, and is moved out from the opening of the lower fruit receiving basin 2 by inertia. Since the operator is familiar with the corresponding fruit specifications loaded in each receiving hopper 26, the removed fruit can be accurately classified, packaged and placed.

[0046] It should be pointed out that, since each receiving hopper 26 is not far apart, in order to avoid fruits of other specifications 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 relevant parameters set. It is appropriate to use the position of the hopper mouth just flush with the receiving hopper 26 to ensure space for more fruits and prevent them from falling out and mixing. Similarly, when two or more receiving hoppers 26 meet the judgment of the controller being full at the same time, the electric door mechanisms of the corresponding receiving hoppers 26 should be opened in sequence according to the set discharge logic relationship to achieve the purpose of orderly discharge and collection.

[0047] In the above content, the opening and closing actions of the electric door mechanism are specifically as follows: Figure 8 As shown in Figure a and Figure b in the figure, in the direction from Figure b to Figure a, the camera 27 compares the real-time photographic image with the preset image or data, and the controller determines that the full opening condition is met, and sends an opening instruction to the first stepper motor 41 and the second stepper motor 42 at the same time, and the output end of the first stepper motor 41 drives the first support rod 51 to rotate in the clockwise direction (by Figure 8The output end of the second stepper motor 42 drives the fifth support rod 55 to rotate in the counterclockwise direction, and the first support rod 51 drives the coaxially hinged second support rod 52 to move synchronously, and causes the first baffle 43 hingedly connected to the second support rod 52 to move toward the outside of the discharge hole. Similarly, the fifth support rod 55 drives the coaxially hinged sixth support rod 56 to move synchronously, and causes the second baffle 44 hingedly connected to the sixth support rod 56 to move toward the outside of the discharge hole. Both baffles move outward to form an open door shape and expose the discharge hole (as shown in the direction ... Figure 7 The fruit in the receiving hopper 26 falls into the lower fruit receiving basin 2 through the discharge hole.

[0048] The controller presets the opening time to keep the opening state for a period of time. After the preset time is up, the controller sends a closing command to the two stepper motors. Figure 7 as well as Figure 8 As shown in Figure a to Figure b, in the order of Figure a to Figure b, at this time, the output end of the first stepper motor 41 drives the first support rod 51 to rotate counterclockwise (according to Figure 8 The output end of the second stepper motor 42 drives the fifth support rod 55 to rotate in the clockwise direction, thereby driving the two baffles to rotate simultaneously and move closer to each other to form a closed door shape, blocking the discharge port of the receiving hopper 26. Each electric door mechanism works in this way in an orderly manner so that fruits of various specifications can be quickly classified and packaged.

[0049] Among them, in order to ensure the movement stability of the two baffles, a second connecting pin 46 is provided at the lower end of the first baffle 43, the second connecting pin 46 is hingedly connected to one side of the third support rod 53, the other side of the third support rod 53 is coaxially hingedly arranged with one side of the fourth support rod 54, and the other side of the fourth support rod 54 is hingedly connected to the support frame 4; similarly, a fourth connecting pin 48 is provided at the lower end of the second baffle 44, the fourth connecting pin 48 is hingedly connected to one side of the seventh support rod 57, the other side of the seventh support rod 57 is coaxially hingedly arranged with one side of the eighth support rod 58, and the other side of the eighth support rod 58 is hingedly connected to the support frame 4; two identical transmission connection structures are provided on each baffle, which can not only support the baffle to prevent the fruit from leaking, but also ensure the movement stability during the opening and closing process.

[0050] According to the above content, the picked fruits are directly sent to the upper fruit receiving basin 1, and flow through two rail frames and fall into the receiving hoppers 26 of corresponding specifications respectively. At the position of the receiving hoppers 26, they fall into the lower fruit receiving basin 2 in an orderly manner and are quickly classified, packaged and placed. The turnover time of the whole process is fast, and the movement height of each link is not large. It is not easy to cause damage to citrus fruits, which improves the quality rate of fruits. They are classified and packaged as they are picked, reducing transportation costs. In order to better reduce circulation damage, the discharge holes of the three receiving hoppers 26 at the upper end are all arranged vertically downward, and the discharge hole of the lowest receiving hopper 26 is arranged horizontally outward.

[0051] The camera 27 and the connected controller used in this embodiment are both uses of the existing technology and do not involve the adjustment of the control program, so the preset use of the camera 27 and the controller will not be repeated here.
