[0021] To clearly illustrate the technical features of the scheme, the following through specific implementation, the scheme is described.

[0022] As Figure 1 The utility model discloses an apple damage reduction vertical conveying device, including rack 4, annular conveying chain 5 of rotation setting on the rack and the drive motor 7 of driving annular conveying chain rotation, and the drive motor adopts step motor, the annular conveying chain 5 extends along the vertical, due to the annular characteristics of annular chain, forms the ascending section and the descending section, and the specific installation structure of annular conveying chain and drive motor adopts prior art, no longer repeats.

[0023] The annular conveying chain is provided with a plurality of fruit holders 6, which are arranged in sequence and at intervals along the length direction of the annular conveying chain. The frame is fixedly provided with a feeding hopper 402 located at the ascending section of the fruit holder, and the feeding hopper is located at the side of the plane where the annular conveying chain is located. In this embodiment, the annular conveying chain is arranged in two rows to improve stability, and the feeding hopper is located at the left side or the right side of the vertical plane where the annular conveying chain is located.

[0024] The fruit holder comprises a connecting seat 601 fixedly connected with the annular conveying chain, and a holder plate 603 hingedly connected with the connecting seat through a horizontal shaft 604. The upper surface of the holder plate is provided with a buffer layer, such as a rubber pad, to reduce the damage to the surface of the apple. The lower part of the holder plate is provided with a gas spring 602 hingedly connected with the connecting seat at one end, and the other end of the gas spring is hingedly connected with the holder plate 603. The hinged point of the gas spring and the holder plate is located between the horizontal shaft 604 and the feeding hopper, and the axis of the horizontal shaft is parallel to the vertical plane where the annular conveying chain is located. The frame is fixedly provided with a limiting block 401 located above the feeding hopper and matched with the end of the holder plate close to the feeding hopper. The end of the holder plate close to the feeding hopper is the sliding end, and the limiting block blocks the sliding end. With the movement of the annular conveying chain, the holder plate is inclined downward with the sliding end downward, so that the apple slides from the holder plate to the feeding hopper. In this embodiment, the horizontal shaft is fixedly connected with the connecting seat, and a shaft sleeve is sleeved on the horizontal shaft. The shaft sleeve is fixedly connected with the bottom surface of the holder plate, and the shaft sleeve can rotate on the horizontal shaft, thereby realizing the rotation of the holder plate around the axis of the horizontal shaft.

[0025] The upper surface of the holder plate of the ascending section is fixedly provided with an upwardly extending stop edge located at the end of the holder plate close to the annular conveying chain and the end of the holder plate away from the feeding hopper, to prevent the apple from falling during the ascending process. The side of the holder plate facing the feeding hopper is provided with an opening without a stop edge, to ensure that the apple reliably slides when the holder plate is blocked and inclined.

[0026] In this embodiment, a beveled edge matched with the limiting block is arranged on the stop edge close to the annular conveying chain. The beveled edge and the limiting block are matched to block the holder plate and incline the holder plate, and the holder plate is easily separated from the limiting block to avoid being blocked.

[0027] This embodiment further comprises a conveying pipe 1 fixedly arranged below the feeding hopper and corresponding to the ascending section of the fruit holder. The conveying pipe is located at the lower part of the ascending section and faces the holder plate at the lowermost end of the ascending section. The conveying pipe 1 is arranged at an inclination, and the end of the conveying pipe close to the fruit holder is lower than the other end. The apple slides along the conveying pipe to the holder plate at the lowermost end of the ascending section.

[0028] A first infrared sensor 2 is installed on the side wall of the conveyor pipe near the fruit tray, and the first infrared sensor is electrically connected to the drive motor. A second infrared sensor 3 is installed on the frame, located on one side of the conveyor pipe and adapted to the fruit tray in the ascending section. The second infrared sensor is also electrically connected to the drive motor. The first infrared sensor is used to detect apples passing through the end of the conveyor pipe, and the second infrared sensor is used to detect whether the tray is in position. When the second infrared sensor detects the tray, the drive motor stops working and waits for the apple to fall from the conveyor pipe onto the tray. When the first infrared sensor detects that an apple has passed the end of the conveyor pipe, the drive motor starts, improving the level of automation. The control program used to control the working state of the drive motor based on the signals from the infrared sensors is conventional technology and will not be described in detail.

[0029] The frame is also fixed with an outer shell of the fruit tray located in the rising section of the enclosure. The dropping hopper is fixed to the upper end of the outer shell. The lower part of the outer shell has a feeding hole for connecting the conveying pipe. The gap between the inner wall of the outer shell and the tray is smaller than the outer dimensions of the apple to prevent the apple from falling during the rising process before reaching the dropping hopper.

[0030] In this embodiment, when the conveying device is in use, the second infrared sensor detects that the fruit tray has reached the designated position and controls the stepper motor to stop running. The fruit tray waits at this position for apples to be conveyed. When the apples pass the first infrared sensor along the conveyor pipe, they enter the fruit tray, and the stepper motor restarts, driving the circular conveyor chain to rotate, thereby moving the fruit tray and apples upward. When the fruit tray passes the limit block, the tray plate is automatically rotated by the limit block, smoothly releasing the apples into the hopper, greatly reducing the apple damage rate. As the circular conveyor chain continues to move, the tray plate separates from the limit block, the limit block loses its blocking effect on the tray plate, and the tray plate returns to its initial state under the action of the gas spring.

[0031] This device, through a combination of automatic control and mechanical design, effectively reduces the damage rate of apples during the upward conveying process, improves harvesting efficiency and quality, ensures that apples can be picked and transported in a timely and efficient manner during the harvest season, enhances fruit quality, and thus increases the planting income of fruit farmers and the benefits of the industry.
