Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a lifting and closing structure of a picking and conveying device. Background Art

[0002] For large crop planting bases, the traditional method of relying on manual picking and then transporting to loading trucks is very time-consuming and labor-intensive. Therefore, many auxiliary picking tools have appeared on the market, including installing conveyor belts on picking vehicles. The conveyor belts can extend to the crop planting site. After the pickers pick the crops, they only need to put them on the conveyor belts, and the conveyor belts will transport the crops back to the collection trucks. However, the conveyor belts of most picking devices on the market are not long enough and the range of extension is not wide enough. The fundamental reason is that the conveyor belts are not easy to store when not in use, and the conveyor belts must be higher than the crops. If the conveyor belts are lower than the crops when moving, they will hit the crops and cause damage to the crops.

[0003] The technical content disclosed in the Chinese patent document (Announcement No.: CN206155864U, Patent Name: Fruit Conveying and Packing Equipment) is: In order to prevent the collecting conveyor belt from falling, a gas spring is installed between the collecting frame and the rotating support to support and cushion the collecting conveyor belt. When the pickers are at a higher position, the height of the outer end of the collecting conveyor belt is higher to prevent the outer end of the collecting conveyor belt from falling and causing damage to the equipment. In order to keep the outer end of the collecting conveyor belt at a certain height, a strut can be installed on the collecting frame, and a fixed seat is hinged on the collecting frame. One end of the strut is hinged on the rotating support, and the other end is slidably installed in the sliding hole set in the fixed seat. A locking bolt is installed on the fixed seat, and the inner end of the locking bolt contacts the strut. Tighten the locking bolt and fix the strut, so that the collecting conveyor belt can be fixed to the rotating support, so that the outer end of the collecting conveyor belt is kept at a certain height and the outer end of the collecting conveyor belt is propped up.

[0004] It can be seen from the above implementation scheme that the conveyor belt is not provided with a corresponding storage mechanism, which is not conducive to the folding of the conveyor belt and is not convenient for the movement of the equipment. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and is provided with a lifting and opening and closing structure, which can realize the lifting and lowering of the picking conveyor belt and the storage to the side of the collecting vehicle, thereby solving the problem that the picking conveyor belt is inconvenient to store and collides with higher crops during movement.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] A lifting and opening and closing structure of a picking and conveying device comprises a collecting vehicle, the collecting vehicle comprises a vehicle body component, the vehicle body component is provided with a lifting base, a lifting frame body is slidably connected to the lifting base, an opening and closing frame body is rotatably connected to one side of the lifting frame body, and a picking conveyor belt is hingedly connected to the opening and closing frame body;

[0008] The picking conveyor belt can be raised and lowered relative to the vehicle body component, the picking conveyor belt can be rotated around one side of the vehicle body component, and the picking conveyor belt can be stored at one side of the vehicle body component.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] A lifting and opening and closing structure is provided to realize the lifting and lowering of the picking conveyor belt and its storage to the side of the collecting vehicle, so that the picking conveyor belt can be stored to the side of the collecting vehicle when not in use. By stopping the collecting vehicle in one place, the picking conveyor belt can be extended to the area on the side of the collecting vehicle, which is convenient for picking and collecting crops. On the other hand, when the picked crops are relatively high, such as corn, the picking conveyor belt can be raised when the collecting vehicle moves to prevent the picking conveyor belt from hitting the crops and causing damage to the crops when the collecting vehicle moves.

The lifting power component 6 is an electric cylinder or an oil cylinder; the lifting power component 6 provides power for the lifting and lowering of the lifting frame body 3, and the lifting frame body 3 is connected to the picking conveyor belt D, so the picking conveyor belt D can be raised and lowered during use to avoid crops.

[0024] The lifting frame 3 is connected to the opening and closing power component 5, the output end of the opening and closing power component 5 is connected to the opening and closing frame 4, the opening and closing power component 5 is an electric cylinder or an oil cylinder, when the output rod of the opening and closing power component 5 is pushed out, the picking conveyor belt D can be received to the side of the collection vehicle B, when the output rod of the opening and closing power component 5 is retracted, the picking conveyor belt D can be perpendicular to the collection vehicle B, at this time, the crops in the distance can be placed on the picking conveyor belt D and transported back to the collection vehicle B.

[0025] A counterweight block 8 is provided on the side of the vehicle body component 1 away from the picking conveyor belt D. The counterweight block 8 and the picking conveyor belt D are respectively located on both sides of the collecting vehicle B, so that the collecting vehicle B is balanced and the operation of the collecting vehicle B is more stable.

[0026] The hinge block 402 is hinged to the hinge seat 303, and the baffle 302 is provided on one side of the lifting frame body 3. When the opening and closing frame body 4 is arranged in parallel with the lifting frame body 3, one side of the hinge block 402 is in contact with the baffle 302. When the output rod of the opening and closing power component 5 contracts, the opening and closing frame body 4 is pulled in a direction parallel to the lifting frame body 3, and the picking conveyor belt D moves in a direction perpendicular to the collecting vehicle B. When the opening and closing frame body 4 is pulled to be in contact with the baffle 302, the movement of the opening and closing frame body 4 and the picking conveyor belt D stops, and the baffle 302 limits the moving range of the opening and closing frame body 4, so that the picking conveyor belt D can be unfolded to a specific position each time it is unfolded, making the operation of the opening and closing structure more stable.

[0027] A lock buckle 301 is provided on the side of the lifting frame body 3 away from the hinge seat 303, and a lock plate 401 is provided on the side of the opening and closing frame body 4 away from the hinge block 402. When the opening and closing frame body 4 is arranged parallel to the lifting frame body 3, the lock plate 401 is locked with the lock buckle 301 together. In this way, when the opening and closing frame body 4 is pulled to fit with the baffle 302, the lock buckle 301 on the other side of the opening and closing frame body 4 away from the baffle 302 is locked, so that the opening and closing frame body 4 can no longer move, thereby ensuring the stability of the position of the picking conveyor belt D during work, and also ensuring the installation of the pickers without being hit by the movement of the picking conveyor belt D.

[0028] A wheel assembly 2 is arranged below the body assembly 1, and the wheel assembly 2 includes a frame connector 201, and the frame connector 201 is hinged with a wheel swing frame 203. Both ends of the wheel swing frame 203 are connected to the wheel 204, and the frame connector 201 and the wheel swing frame 203 are rotatably plugged with the wheel swing shaft 202, so that the wheel swing frame 203 can swing relative to the body assembly 1. Because the ground of the farm is generally uneven, when there are some pits on the ground and one of the wheels 204 accidentally falls into the pit, the wheel 204 that is trapped in the pit can be pulled out by swinging the wheel swing frame 203, using the wheel 204 that is not trapped in the pit as a fulcrum. Therefore, the climbing mobile device can be applied to a variety of rugged road surfaces, making the climbing mobile device more applicable.
