Description

Technical Field

[0001] This utility model relates to the field of fruit preservation equipment, and in particular to an inspection device for the storage and preservation of apples after harvesting. Background Technology

[0002] After harvesting apples, fruit farmers need to inspect and classify them before storing them.

[0003] Currently, fruit farmers inspect and grade apples before storage and preservation, checking for excessive dust accumulation and surface damage, as these can affect storage and preservation. However, due to limited apple orchard land, many farmers still manually inspect each apple individually, which is time-consuming, labor-intensive, and inefficient. Therefore, this application relates to an apple post-harvest storage and preservation inspection device for inspecting apples before storage and preservation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an inspection device for the storage and preservation of apples after harvesting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an apple harvesting and storage preservation inspection device, comprising a frame, a screening roller rotatably connected to the top of the frame, the screening roller having a conical cylindrical structure and an arc-shaped groove provided on the screening roller, the inner diameter of the arc-shaped groove gradually increasing from both ends to the middle, rotating rollers provided on both sides of the screening roller, the rotating rollers having a conical cylindrical shape, the rotating rollers being rotatably connected to the frame, the distance between the rotating rollers and the screening roller gradually decreasing from both sides to the middle, a storage box provided in the lower part of the frame, the storage box containing multiple horizontally pull-out transfer boxes, multiple fixing pins on the top of the storage box, a drop-proof net hanging on the top of the storage box via the fixing pins, the drop-proof net having multiple mesh holes extending into the interior of the transfer boxes;

[0006] Through the above technical solution, the conveyor belt can transport apples to the screening rollers. The screening rollers are driven to rotate by the second motor, and the apples enter the arc grooves of the screening rollers. At this time, the first motor causes the rotating roller to rotate. The rotating roller, in conjunction with the gap between the screening rollers, transports apples of different sizes to the center of the screening rollers. Apples of different sizes fall into the corresponding transfer boxes through the arc grooves of different sizes between the screening rollers. When the apples fall into the transfer boxes, they land on the anti-drop net, which provides a cushion. The apples then fall into the transfer boxes through the mesh of the anti-drop net. This allows for inspection of the apples during transport and also enables visual inspection of the apples while they are rotating. This ensures that the apples will not spoil during subsequent storage and also allows for fruit grading, facilitating subsequent sales.

[0007] As a further description of the above technical solution:

[0008] The frame has supports on both sides, and conveyor belts are installed on the supports. The inner side of the conveyor belts is positioned directly above the screening rollers.

[0009] Through the above technical solution, the conveyor belt can transport apples from both sides to the screening rollers, realizing the transportation and inspection of apples.

[0010] As a further description of the above technical solution:

[0011] One end of the screening roller is connected to the drive shaft of a second motor, which is located on the outside of the frame.

[0012] Through the above technical solution, the second motor drives the screening roller to rotate via the drive shaft, thereby achieving apple size screening and rotation, and enabling the inspection of apple appearance defects.

[0013] As a further description of the above technical solution:

[0014] Each of the rotating rollers is fixedly connected to a second sprocket at one end. The second sprocket is connected to a first sprocket via a chain. The first sprocket is fixedly connected to the drive end of a first motor, which is mounted on the outside of the frame.

[0015] Through the above technical solution, the first motor drives the chain to drive the second sprocket through the first sprocket, so that the rotating roller can rotate on both sides of the screening roller.

[0016] As a further description of the above technical solution:

[0017] The fall protection net is provided with multiple parallel hanging straps, each of which has a hanging hole, and each hanging hole is engaged with a fixing pin.

[0018] With the above technical solution, the anti-fall net is hung on the top of the storage box by fixing pins and hanging holes. In this way, the apples are cushioned when they fall from the sorting roller and will not be broken when they fall into the transfer box.

[0019] As a further description of the above technical solution:

[0020] A box for spoiled fruit is provided on one side of the frame;

[0021] The above technical solution enables the bad fruit box to store apples with appearance defects and damage.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, a conveyor belt transports apples to a screening roller, allowing for visual inspection. Damaged apples can be screened directly without manual handling. Simultaneously, during apple grading, the screening roller is driven to rotate by a second motor. Apples enter the arc-shaped grooves of the screening roller. At this time, a first motor causes a rotating roller to rotate. The gap between the rotating roller and the screening roller causes the apples to rotate further due to the operation of the screening roller and the rotating roller. Workers can remove defective apples, ensuring proper storage. Different sizes of apples are transported towards the center of the screening roller. Apples of different sizes fall into corresponding transfer boxes through the arc-shaped grooves of different sizes between the screening rollers. When falling into the transfer box, the apples land on a shock-absorbing net, which provides cushioning. The apples then fall through the mesh of the shock-absorbing net into the transfer box. This allows for inspection during transport and also enables visual inspection while rotating the apples. This ensures that the apples do not rot during subsequent storage and facilitates fruit grading for easier sale. Attached Figure Description

In this way, the apples are cushioned when they fall from the screening roller 13 and will not be broken when they fall into the transfer box 5.

[0036] A spoiled fruit box 18 is provided on one side of the rack 1. The spoiled fruit box 18 can store apples with appearance defects and damage.

[0037] Working principle: After the apples are inspected, the conveyor belt 3 transports them to the screening roller 13. During transport, the apples are visually screened to prevent damage during storage. The screening roller 13 is driven to rotate by the second motor 14. The apples enter the arc groove of the screening roller 13. At this time, the first motor 11 causes the rotating roller 15 to rotate. The rotating roller 15, in conjunction with the gap between the screening roller 13, transports apples of different sizes to the center of the screening roller 13. Apples of different sizes fall into the corresponding transfer box 5 through the arc grooves of different sizes between the screening rollers 13. When the apples fall into the transfer box 5, they land on the anti-drop net 6, which provides a cushion. The apples then fall into the transfer box 5 through the mesh 9 of the anti-drop net 6. This allows for inspection of the apples during transport and also enables visual inspection during rotation. This ensures that the apples will not rot during subsequent storage and also allows for fruit grading, facilitating subsequent sales.
