Abstract
Description
Technical Field
[0001] This utility model relates to an agricultural machine, and more particularly to a crop conveying device, specifically a conveyor belt-based reed seedling conveying device. Background Technology
[0002] After seedlings of crops such as Artemisia argyi are cultivated, they often need to be sorted before being transported to planting sites for cultivation. To improve sorting and loading efficiency, some mechanical devices have been developed. For example, Chinese patent "A Mechanical Seedling Dispensing Device for Artemisia argyi Cuttings" (Publication No.: CN 210053829U) discloses a mechanical seedling dispensing device for Artemisia argyi cuttings, including a seedling stalk box and a belt mechanism. This belt mechanism is installed directly below the seedling stalk box and consists of a belt and rollers. The belt has a certain thickness and has arc grooves; the grooved belt meshes with the toothed rollers, allowing the seedlings to fall in an orderly, spaced manner as the belt rotates, thus separating the seedlings. However, this device has low conveying efficiency and strict requirements on the diameter of the Artemisia argyi seedlings, leading to problems such as jamming and empty slots, making it difficult to meet usage requirements.
[0003] Therefore, improvements are urgently needed to better meet the needs of agricultural production. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] like Figures 1 to 3 As shown.
[0027] A conveyor belt-based reed seedling transport device includes a conveyor belt 2 and baffles 5, etc.
[0028] The conveyor belt 2 is a flat conveyor belt, mounted on the frame 1, on which the reed seedlings can be placed and transported to a designated location. The frame 1 has a lead screw assembly 4 and a guide rail 6 on each side. Both the lead screw assembly 4 and the guide rail 6 are vertically arranged and correspond to each other, with their connecting line perpendicular to the conveyor belt.
[0029] The baffle 5 is elongated, with a length greater than the width of the conveyor belt 2, and spans across the top of the conveyor belt 2 along its width direction. Its two ends are connected to the lead screw assembly 4 and the guide rail 6, respectively. Preferably, the baffle 5 is composed of multiple short plates spliced together. The short plates have an H-shaped cross-section and are arranged longitudinally along their length, with adjacent ends connected by screws. This makes the manufacture and installation of the baffle more convenient and enhances its rigidity, meeting usage requirements.
[0030] The lead screw assembly 4 includes a bracket 42, a lead screw 43, and a slider 44. The bracket 42 is a horizontally placed U-shape, with both ends fixed to the frame 1, and a motor located below its base plate. The lead screw 43 is vertically positioned within the bracket 42, its lower end passing through the base plate of the bracket 42 and connected to the output shaft of the motor, while its upper end is connected to the top plate of the bracket 42 via a bearing, allowing the lead screw 43 to rotate under the drive of the motor. The slider 44 is block-shaped with a screw hole, and is screwed onto the lead screw 43 through this hole. Simultaneously, the slider 44 is connected to one end of the baffle 5, enabling the baffle 5 to move up and down. Preferably, a motor housing 41 is also included, located below the bracket 42. The motor is housed within the motor housing 41 for easy fixation. The motor is a stepper motor, which facilitates control of the lead screw.
[0031] The guide rail 6 is a strip-shaped block with a U-shaped cross-section and an opening facing the conveyor belt 2. The width of the opening is adapted to the end of the baffle 5, so that the baffle 5 can move smoothly along the guide rail 6 and guide and limit the baffle 5.
[0032] A pressure sensor 3 is provided on the front side of the baffle 5 facing the direction of travel of the conveyor belt 2. This pressure sensor 3 is a thin-film flexible pressure sensor, its length being approximately equal to the length of the baffle 5 and arranged along its length direction. It can sense the pressure generated when the asparagus seedlings are stacked on the conveyor belt. Simultaneously, the pressure sensor 3 is electrically connected to a controller to transmit the sensed pressure information to the controller, facilitating subsequent control. Preferably, the controller is a 32-bit microcontroller, located inside the motor housing 41 and electrically connected to the motor, enabling it to control the motor's start and stop based on the information from the pressure sensor, thereby driving the baffle to move up and down. The pressure sensor can be an RP-L flexible thin-film resistive pressure sensor.
[0033] Furthermore, a Hall effect module is provided near the bottom of the slider on the baffle 5. This Hall effect module is electrically connected to the controller and can stop the motor from rotating when the baffle descends to its lowest point, ensuring operational safety.
[0034] The working process of this utility model is as follows:
[0035] During the conveying of Artemisia seedlings, the baffle will default to its lowest point. The height of this lowest point is determined by the diameter of a single Artemisia seedling. In this embodiment, the lowest point is set approximately 10mm above the conveyor belt to restrict the passage of seedlings, preventing them from stacking together. When a blockage occurs due to excess seedlings, the seedlings will touch the pressure sensor on the baffle. When the pressure sensor's threshold is reached, the controller sends a command to the motor, causing it to start and rotate the lead screw, raising the baffle and allowing a certain number of seedlings to pass through, thus eliminating the blockage. The height the baffle rises is determined by the amount of stacked seedlings. When the stack is large, the pressure sensor reading will remain above the threshold. In this case, the baffle will continue to rise until the seedlings no longer press against the sensor, or until the maximum height of the slide rail (200mm) is reached. Then, the baffle will automatically fall back to the lowest point. If seedlings touch the pressure sensor again and reach the pressure sensor threshold, the baffle will rise again. Therefore, by moving the baffle up and down, the problems of stacking and blockage that may occur during the transportation of Artemisia argyi seedlings can be eliminated in time, ensuring smooth transportation of Artemisia argyi seedlings.
[0036] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
