The second rotating disk 39 is provided with a plurality of engaging grooves 40 adapted to engage with the limiting hook rod 37, and the engaging grooves 40 are divided into four equal parts on the second rotating disk 39. The number of unloading flaps 42 is four and they are equidistantly arranged, and the limiting hook rod 37 is rotatably connected to the second fixed plate 33 through the fifth connecting shaft 38, and the second fixed plate 33 is fixedly installed on the unloading bin 28.
[0048] Furthermore, the fruit unloading mechanism also includes a first rotating disk 31 and a reset spring 35 for driving the limiting hook rod 37 to perform clamping control. The first rotating disk 31 is rotatably connected to the second fixed plate 33 through the fourth connecting shaft 30. The first rotating disk 31 is provided with a first protrusion 32. A second protrusion 66 that is adapted to be coupled with the first protrusion 32 is provided on one side of the limiting hook rod 37.

[0049] Furthermore, the fruit unloading mechanism also includes a first connecting shaft 22 and a tooth plate 19 for driving the first rotating disk 31 to rotate, the tooth plate 19 is fixedly connected to the push block 16 through the connecting plate 18, and the connecting plate 18 is limitedly slidably connected to the second docking plate 12, the tooth plate 19 is meshingly connected with the first gear 20, the first gear 20 is installed on the first connecting shaft 22 through a one-way bearing 21, the first connecting shaft 22 is rotatably installed at the bottom of the second docking plate 12 through the first fixed plate 23, and the first connecting shaft 22 is movably installed and connected to the second connecting shaft 25 through the universal joint 24, the second connecting shaft 25 is rotatably connected to the third connecting shaft 27 through the first synchronous belt 26, the third connecting shaft 27 is rotatably installed on one side of the unloading bin 28, and the third connecting shaft 27 is rotatably connected to the fourth connecting shaft 30 through the second synchronous belt 29.
[0050] Preferably, when picking agricultural fruits, the walking mechanism 1 is moved, the rotating table 2 drives the collecting box 4 and the receiving hopper 5 to rotate, and the electric lifting cylinder 3 drives the collecting box 4 and the receiving hopper 5 to adjust the height. When a certain height position is reached for picking, the electric push rod 17 drives the pushing block 16 to move toward the receiving hopper 5, so that the scissor blades 13 move under the drive of the pushing block 16, and under the guiding drive action of the set driving groove 10 and the guide rod 15, the two scissor blades 13 are crossed with each other, thereby realizing the cutting and picking of the fruit.
[0051] When the fruits are cut and picked, they can fall into the receiving hopper 5 below. The buffer plate 7 on the receiving hopper 5 provides buffering to prevent the fruits from falling. The fallen fruits enter the lower bin 28 from the receiving hopper 5. The lower bin 28 has a lower material flap 42 for buffering and limiting. Even if multiple fruits fall, the fruits are arranged in order in the lower bin 28 and on one side of the lower material flap 42. Whenever the electric push rod 17 drives the tooth plate 19 connected to the pushing block 16 to move back and forth for a cycle, such a In this state, when the toothed plate 19 moves toward the receiving hopper 5, under the unidirectional action of the one-way bearing 21, the first gear 20 rotates but cannot drive the first connecting shaft 22 to rotate accordingly, and when the toothed plate 19 moves to a direction away from the receiving hopper 5 to reset, due to the unidirectional action of the one-way bearing 21, the rotation of the first gear 20 drives the first connecting shaft 22 to rotate accordingly, and the first connecting shaft 22 drives the second connecting shaft 25 to rotate under the connection relationship of the universal joint 24, and the second connecting shaft 25 is connected to the first synchronous belt. 26, the third connecting shaft 27 is driven to rotate under the synchronous driving action of the second synchronous belt 29. At this time, the third connecting shaft 27 drives the first rotating disk 31 on the fourth connecting shaft 30 to rotate under the synchronous driving action of the second synchronous belt 29. Therefore, under the relationship of the first protrusion 32 on the first rotating disk 31 and the second protrusion 66 on the limiting hook rod 37 being in contact and connected, the limiting hook rod 37 is driven to rotate in the direction away from the second rotating disk 39. At this time, the limiting hook rod 37 is away from the position where it is in contact and connected with the clamping groove 40 on the second rotating disk 39. The fruit located in the middle of the crossed unloading flap 42 drives the unloading flap 42 to rotate 90° clockwise under the condition of the inclination of the unloading bin 28 and its own gravity. Under the elastic resetting action of the resetting tension spring 35, the limiting hook rod 37 is now engaged with the connecting groove 40 at a place on the second rotating disk 39 to the connecting groove 40 at the next station. Therefore, the next fruit moves to the middle of the crossed unloading flap 42 under the inclination of the unloading bin 28 and its own gravity to be limited, that is, the unloading operation of the fruits is realized one by one. Figure 8 shown.
[0052] The electric push rod 17 drives the scissor blades 13 to quickly complete the picking action. Compared with manual picking, it is faster and more efficient, replaces a large number of manual operations, reduces labor intensity, reduces labor costs, and the synchronous one-by-one feeding method greatly reduces the collision and squeezing between fruits, and maintains the integrity of the fruits to a greater extent, thereby improving the picking efficiency, increasing the fruit yield and the overall economic benefits.

[0055] The fruit screening mechanism is installed on one side of the first connecting seat 47 and is synchronously driven by the fruit conveying mechanism to screen and place the fruits conveyed from the first connecting seat 47 step by step.

The worm gear 53 is rotationally connected to the first connecting seat 47, and the worm gear 53 is rotationally connected to the output shaft of the drive motor 49 through the third synchronous belt 52.
[0058] Furthermore, the fruit screening mechanism includes a rotating distributing barrel 62 for screening processing, a collecting box 64 is fixedly installed on the side of the first connecting seat 47, and the rotating distributing barrel 62 is provided with sieve holes 63 that increase step by step, and the sieve holes 63 with smaller apertures are arranged close to the side of the conveyor belt 56. The rotating distributing barrel 62 is rotatably connected to the collecting box 64 through a ninth connecting shaft 61. The cavity inside the rotating distributing barrel 62 is inclined toward the second connecting seat 67, and the ninth connecting shaft 61 is fixedly installed inside the rotating distributing barrel 62 through a support rod 68. A plurality of drawers 65 are arranged on the collecting box 64, and a box door 6 is arranged on one side of the drawer 65. The box door 6 is arranged and installed on one side of the collecting box 4.
[0059] Furthermore, the fruit screening mechanism also includes an eighth connecting shaft 59 for driving the rotating distribution barrel 62 to rotate, the ninth connecting shaft 61 is rotatably connected to the eighth connecting shaft 59 through a bevel gear pair 60, the eighth connecting shaft 59 is rotatably connected to the collecting box 64, and the eighth connecting shaft 59 is rotatably connected to the worm 53 through a fourth synchronous belt 58.
[0060] Preferably, in this embodiment, the fruits discharged from the discharge bin 28 fall onto the third rotating disk 43 one by one, and the limiting enclosure 46 on the third rotating disk 43 performs corresponding limiting processing. At this time, the output shaft of the driving motor 49 drives the second gear 50 to rotate, and the third rotating disk 43 on the seventh connecting shaft 44 is driven to rotate counterclockwise under the relationship of meshing connection between the second gear 50 and the third gear 51. Fig.10 and Fig.13 As shown, at this time, the fruits on the third rotating disk 43 are transported toward the first connecting seat 47 under the action of the limiting of the limiting enclosure 46 and the rotational driving force of the third rotating disk 43.
[0061] The output shaft of the driving motor 49 drives the worm 53 to rotate under the synchronous driving action of the third synchronous belt 52 while rotating, and drives the first transmission roller 55 to rotate under the meshing connection relationship between the worm 53 and the worm wheel 54, so that the conveyor belt 56 is driven to perform continuous transmission and conveying processing under the transmission connection relationship between the conveyor belt 56 and the first transmission roller 55 and the second transmission roller 57 respectively. In addition, the worm 53 rotates and the eighth connecting shaft 59 is driven to rotate under the synchronous driving action of the fourth synchronous belt 58. The eighth connecting shaft 59 is connected to the bevel gear pair. Under the connection relationship of 60, the rotating dividing barrel 62 on the ninth connecting shaft 61 is driven to rotate. At this time, the fruits transmitted to the conveyor belt 56 are conveyed one by one into the rotating dividing barrel 62 for rotary screening. Since the sieve holes 63 provided on the rotating dividing barrel 62 are gradually enlarged, and the cavity in the rotating dividing barrel 62 is inclined toward the second connecting seat 67, fruits of different sizes are classified and screened one by one into the drawer 65 for storage, and a box door 6 is correspondingly provided on the outer side of the collecting box 4 to facilitate the taking and collection of the fruits.
[0062] The third rotating disk 43 can evenly convey the fruits to the conveyor belt 56 by driving the third rotating disk 43 to rotate counterclockwise, so that the conveyor belt 56 synchronously conveys the fruits to the rotating material distribution barrel 62, thereby avoiding accumulation and blockage of the fruits during the conveying process. Compared with the traditional conveying method, the counterclockwise rotating conveying method of the third rotating disk 43 has higher stability and continuity, and improves the conveying efficiency. In addition, the rotating material distribution barrel 62 is arranged in order according to the different sizes of the sieve holes, which can effectively separate the fruits of different sizes.
[0063] At the same time, the counterclockwise rotation of the third rotating disk 43 allows the fruit to enter the rotating dividing barrel 62 more stably, thereby improving the accuracy of screening. During the transportation process of the third rotating disk 43, the fruit is affected by the centrifugal force and can maintain a stable posture, reducing collision and friction with the equipment. The integration of the third rotating disk 43 and the rotating dividing barrel 62 realizes the simultaneous transportation and screening, reduces intermediate links, improves production efficiency, has a high degree of automation, reduces manual labor intensity, and improves the overall efficiency of the production line.
