DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Reference Figures 1 to 5 , an automatic collection system for apple picking, comprising an adsorption device 1 and a buffer device 2, wherein the buffer device 2 is located on the side of the adsorption device 1, and the adsorption device comprises a box top cover 101, with two pipe holes left on the top cover, a vacuum suction device on the top, and the side pipe holes as apple suction ports; the box top cover 101 is connected to the box side cover 102 by screws, and there are two side covers in total; the box side cover 102 is connected to the connecting plate 103 by screws, and the connecting plate serves to connect the adsorption device with the buffer device and the main frame. The so-called main frame refers to a mechanism composed of all parts except these two devices; the connecting plate 103 is connected to the transmission main shaft 107 through a bearing 106, and the shaft serves to transmit power, and the connecting plate also serves as a bearing end cover. The shaft and the connecting plate together limit the bearing, and at the same time, the transmission main shaft 107 is a common transmission shaft for the adsorption device 1 and the buffer device 2. The transmission main shaft 107 is connected to the fruit transfer wheel 104 by screws. The fruit transfer wheel and the box top cover 101 form a semi-closed space structure at multiple angles within a rotation cycle, so that the suction force is enhanced and the apples are successfully sucked in and fall into the groove of the fruit transfer wheel. At this time, the wheel and the shaft rotate together to continuously transport the apples.

[0018] The buffer device 1 includes a self-assembled reversing reducer 201. Since the output directions required by the adsorption device and the buffer device are different and they share the same transmission main shaft in order to reduce the power source, a reversing reducer is required for transmission reversal. The self-assembled reversing reducer 201 is connected to the rim 208 through a screw limiter. The rim is one of the components of the buffer wheel and is the main body thereof. The rim 208 is connected to the straight connecting rod 209 through a screw. The straight connecting rod 209 is connected to the plastic soft rod 210 through an external threaded joint 211. A flexible baffle 212 is embedded on the plane formed by the straight connecting rod 209 and the plastic soft rod 210. The above parts constitute a buffer wheel. The buffer wheel has the function of catching the falling apples and reducing their kinetic energy and reducing the mechanical damage of the apples. At the same time, the buffer wheel can play the role of leveling the apples when rotating, making it more convenient to collect apples and pack them. The self-assembling reversing reducer 201 is connected to the transmission reversing reducer 202 via a reducer coupling 206. Due to space limitations and the need for multi-stage reduction, a reversing reducer is also required in series. The transmission reversing reducer 202 is connected to the motor shaft of the transmission motor 205 via a motor coupling 207. The motor coupling serves as a connection between the shafts, and the transmission motor provides power for the adsorption device and the buffer device. The transmission reversing reducer 202 is connected to the transmission motor 205 via a reducer connecting plate 203 and a transmission motor connecting plate 204, all of which are connected by screws.

[0019] The self-assembling reversing reducer 201 includes a reducer side plate 2011, which is threadedly connected to a connecting plate 103. The side plate and connecting plate each have two pieces, forming a closed structure and attached to the main frame, ensuring stable operation of the reducer and preventing the ingress of dust and other particles. The connecting plate 103 is connected to a transmission main shaft 107 via a bearing 106. The transmission main shaft 107 is keyed to a large bevel gear 2013, which meshes with a small bevel gear 2012. The small bevel gear 2012 is keyed to a low-speed shaft 2016, functioning to transmit power, convert power direction, and reduce speed. The low-speed shaft 2016 is provided with a bearing 106 at its shoulder. The bearing 106 is restrained by a bearing end cap 2015, which is screwed to the reducer bottom cover 2014. The end cap and bottom cover simultaneously support and secure the bearing and shaft, ensuring shaft rotation.

[0020] The adsorption device and the buffer device are connected to the top plate 12 by screw connection. A plurality of reinforcing ribs 11 are provided on the top plate 12, and the reinforcing ribs play the role of strengthening the top plate and improving its strength. The top plate 12 is also provided with a speed regulator 18, and the speed regulator plays the role of adjusting the speed of the buffer device motor. The top plate 12 is connected to the slide 5 by screw connection, and the slide 5 can slide up and down on the support guide rod 3, playing the role of moving the top plate and the adsorption device and the buffer device connected to the top plate up and down, so that the apples can be accumulated from low to high and the apple frame can be easily put in and taken out. The top end of the support guide rod 3 is connected to the retaining ring 4 by screw connection, which plays the role of limiting the top plate to prevent it from falling out. The tail end of the support guide rod 3 is connected to the guide rod base 7 by mechanical limiting, and the guide rod base fixes and supports the support guide rod by mechanical limiting methods such as friction. The guide rod base 7 is screwed to the longitudinal base plate 8 and the transverse base plate 9. The longitudinal and transverse base plates each have two sections, which together form the base of the automatic collection device and are equipped with pre-reserved connection holes for connection to other devices. A positioning slider 6 is positioned in the middle of the support guide rod 3. This positioning slider 6 is connected to the transverse base plate 9 via a limit rod 10. The limit rod is screwed to the positioning slider and transverse base plate, supporting and limiting the positioning slider. The positioning slider 6 is connected to different components on each side of the overall device. On one side, it is screwed to a limit baffle 13. On the other side, the positioning slider 6 is connected to a double-ended hook rod 16 via a hook ring 17. The limit baffle restricts the position of the apple basket, preventing it from exceeding the device. The double-ended hook rod also serves as a limiter, but it is designed as a hook rod to facilitate the insertion and removal of the apple basket. A clamping block 15 is clamped to the support guide rod 3 via screws and placed on the positioning slider 6. The clamping block can slide up and down on the guide rod, and the positioning slider serves as a limiter and support. The clamping block 15 is connected to the motor fixing plate 14 by screws, the motor fixing plate 14 is connected to the stepping motor 19, and the stepping motor 19 is connected to the horizontal bottom plate 9 and the top plate 12 by screws. The stepping motor provides power and support for the lifting and lowering of the top plate and the connected mechanism, and the motor fixing plate serves to fix the stepping motor.

[0021] The process of this embodiment is as follows: apples enter the suction device 1 through the apple suction port on the top cover 101 of the box body. They are transported from the upper part of the suction device 1 to the lower part by the fruit transfer wheel 104. They roll on the guide plate 105 and onto the flexible baffle 212 of the buffer device 2. After the impact is reduced, they fall into the pre-set apple basket in the main frame. When the apples accumulate to a certain level, the stepper motor 19 raises the top plate 12. As the apples accumulate, the top plate rises to the limit, and the speed regulator 18 controls the transmission motor 205 to stop. The double-ended hook rod 16 on the hook ring 17 can then be removed to remove the apple basket. After a new apple basket is placed, the stepper motor 19 lowers the top plate 12, and the transmission motor 205 starts to operate, and the apple collection continues.

The scope of protection of the present invention should not be considered limited to the specific embodiments described in these embodiments.
