Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery technology, and in particular to a multi-row soft-disc extrusion rice seedling throwing device. Background Technology

[0002] Currently, rice cultivation in my country mainly involves three methods: transplanting, direct seeding, and sowing. Among these, direct seeding has unique advantages, as it causes less damage to seedlings and allows for faster recovery. However, existing automated direct seeding equipment typically uses a clamping method to pull the seedlings from the seedling tray during the automatic seedling-pulling process. This makes it easy for the clamping device to damage the seedlings during the pulling process, resulting in a longer recovery and greening period after transplanting, and may even reduce the survival rate of the seedlings. Summary of the Invention

[0003] The present invention aims to solve the aforementioned technical problems by providing a multi-row soft-disc extrusion rice seedling throwing device, which can effectively avoid damage to seedlings during the throwing process and improve the survival rate of seedlings.

[0004] This utility model is achieved through the following technical solution: a multi-row soft-disc extrusion rice transplanting device, comprising:

[0005] Main framework;

[0006] The extrusion and detachment mechanism includes a baffle groove, a rotatable camshaft mounted on the main frame, and a drag roller. The baffle groove is mounted on the main frame and has a number of slots corresponding to the seedling tray holes on the seedling tray. The camshaft is located on one side of the middle part of the baffle groove and is connected to a first drive motor that drives it to rotate. The drag roller is mounted on one side of the lower end of the baffle groove and forms a seedling tray outlet with the baffle groove.

[0007] The seedling tray conveying mechanism includes a seedling tray conveyor belt arranged in a ring at the top of the main frame, and an active roller and a driven roller that are respectively driven and cooperated with both ends of the seedling tray conveyor belt. The active roller and the baffle groove form a seedling tray inlet, and the active roller is connected to a second motor that drives its rotation. The drag roller is driven and connected to the active roller.

[0008] The seedling tray recycling mechanism includes a basket located below the seedling tray outlet.

[0009] Preferably, the baffle groove includes a plurality of baffles arranged in parallel, with the groove formed between two adjacent baffles.

[0010] Preferably, the baffle, the drag roller, and the seedling tray conveying mechanism are all mounted on the movable frame, which is slidably fitted with the main frame and connected to a drive cylinder that drives its lateral movement relative to the main frame.

[0011] Preferably, the main frame is provided with a guide rail perpendicular to the direction of seedling tray conveying, and the bottom of the movable frame is provided with rollers that cooperate with the guide rail.

[0012] Preferably, the main frame is equipped with several placement frames for storing seedling trays.

[0013] Preferably, the seedling tray conveyor belt is provided with several push plates evenly distributed around it along its length.

[0014] Preferably, the basket includes a base plate, the edge of which is provided with several baffles fixedly connected to the main frame, and one side of the base plate is connected with an inclined guide plate.

[0025] like Figures 1 to 3 As shown, this application discloses a multi-row soft-disc extrusion rice seedling throwing device, including a main frame 1, an extrusion and detachment mechanism, a seedling tray conveying mechanism, and a seedling tray recycling mechanism, specifically:

[0026] The extrusion and detachment mechanism includes a baffle groove 2, a camshaft 3 and a drag roller 4 rotatably mounted on the main frame 1. The baffle groove 2 is mounted on the main frame 1 and has a number of slots 5 corresponding to the seedling tray holes on the seedling tray. Specifically, the baffle groove 2 includes a number of parallel baffles 13, which are connected and fixed by a fixing rod. The slots 5 are formed between two adjacent baffles 13. The camshaft 3 is located on one side of the middle part of the baffle groove 2 and its two ends are rotatably connected to the main frame 1 through bearing seats. One end of the camshaft 3 is connected to a first drive motor 6 that drives its rotation. The drag roller 4 is mounted on one side of the lower end of the baffle groove 2 and its two ends are rotatably connected to the main frame 1 through bearing seats. The drag roller 4 and the baffle groove 2 form a seedling tray outlet 11.

[0027] The seedling tray conveying mechanism includes a seedling tray conveyor belt 7 arranged in a ring shape at the top of the main frame 1, and a drive roller 8 and a driven roller 9 respectively driven and engaged with both ends of the seedling tray conveyor belt 7. The two ends of the seedling tray conveyor belt 7 are respectively wound around the drive roller 8 and the driven roller 9. Several push plates 19 are evenly distributed around the seedling tray conveyor belt 7 along its length. The push plates 19 form a limiting groove for limiting the seedling tray holes at the bottom of the seedling tray. By setting the push plates 19, the seedling tray can be stably placed on the seedling tray conveyor belt 7 to prevent the seedling tray from moving relative to the seedling tray conveyor belt 7 in the conveying direction. The active roller 8 and the driven roller 9 are rotatably engaged with the main frame 1. The active roller 8 and the baffle 2 form a seedling tray inlet 10. The active roller 8 is connected to a second motor that drives its rotation. The drag roller 4 is connected to the active roller 8. The second motor can drive the active roller 8 and the drag roller 4 to move synchronously. Several support rollers 23 are provided between the active roller 8 and the driven roller 9. The support rollers 23 can support the seedling tray conveyor belt 7 to prevent the seedling tray from collapsing downward after it is placed on the seedling tray conveyor belt 7, thereby ensuring that the seedling tray can be transported horizontally.

[0028] The seedling tray recycling mechanism includes a basket 12 located below the seedling tray outlet 11. The basket 12 can be used to store the seedling trays sent out from the seedling tray outlet 11 for unified collection and processing of the seedling trays after seedling removal. Specifically, the basket 12 includes a base plate 20. The edge of the base plate 20 is provided with several baffles 21 that are fixedly connected to the main frame 1. An inclined guide plate 22 is connected to one side of the base plate 20. The upper end of the guide plate 22 extends to the seedling tray outlet 11, and the lower end is adjacent to one side edge of the base plate 20, so that the seedling trays sent out from the seedling tray outlet 11 slide down onto the base plate 20 through the guide plate 22 for stacking.

[0029] This utility model discloses a multi-row soft-disc extrusion rice seedling throwing device, which includes an extrusion and detachment mechanism, a seedling tray conveying mechanism, and a seedling tray recycling mechanism. The seedling tray conveyor belt 7 transports the seedling trays containing seedlings through the seedling tray inlet 10 to the space between the baffle 2 and the camshaft 3. Then, the first drive motor 6 drives the camshaft 3 to rotate, causing the protruding part on the side of the camshaft 3 away from the axis of rotation to extrude the bottom of the seedling tray, thereby squeezing the seedlings out of the seedling holes in the seedling tray. The extruded seedlings fall through the slots 5 on the baffle 2, thus realizing the seedling throwing. In addition, after the seedlings are removed, the seedling trays are transported to the seedling tray outlet 11 and then transported by the drag roller 4 to the seedling tray recycling mechanism for unified collection and processing. In the entire operation, no manual seedling removal and throwing operations are required, resulting in a high degree of automation and improving the seedling throwing efficiency. At the same time, during the seedling removal process, only the bottom of the seedling tray is extruded, avoiding contact with the seedlings, thus preventing damage to the seedlings and improving the survival rate of the seedlings.

[0030] In one preferred embodiment of this application, the baffle 2, the drag roller 4, and the seedling tray conveying mechanism are all mounted on the movable frame 14. Specifically, the baffle 2 is fixedly mounted on the movable frame 14. The two ends of the drag roller 4 are rotatably engaged with the movable frame 14 through bearing seats. The two ends of the driving roller 8, the driven roller 9, and the support roller 23 are all rotatably engaged with the movable frame 14 through bearing seats. The movable frame 14 is slidably engaged with the main frame 1 and is connected to a drive cylinder 15 that drives it to move laterally relative to the main frame 1. In this application, since the number of cams on the camshaft 3 is less than the number of holes in each row of seedling trays on the seedling tray, it is necessary to drive the movable frame 14 to move laterally through the drive cylinder 15. After each movement, the bottom of the seedling tray is squeezed. Through multiple lateral movements, the entire row of seedling tray holes on the seedling tray is squeezed. Then, the seedling tray is conveyed by the seedling tray conveying mechanism and the drag roller 4, so that the camshaft 3 squeezes the other row of seedling tray holes. The above steps are repeated until the squeezing of the seedling tray holes on the entire seedling tray is completed.

[0031] Furthermore, a guide rail 16 is provided on the main frame 1 perpendicular to the direction of seedling tray conveying, and a roller 17 that cooperates with the guide rail 16 is provided at the bottom of the movable frame 14. Through the rolling cooperation between the roller 17 and the guide rail 16, the movement of the movable frame 14 can be limited, so that the movable frame 14 maintains stable lateral movement.

[0032] In this application, in order to facilitate the storage of seedling trays, a number of placement frames 18 for storing seedling trays are installed on the main frame 1. The placement frames 18 are open-top frames and are fixedly installed on the side edge of the main frame 1.

[0033] In another preferred embodiment of this application, a support foot 24 is provided at the bottom of the main frame 1 to provide support for the main frame 1. Specifically, the upper end of the support foot 24 is connected to the main frame 1 by two pins. When the vehicle needs to fold the support foot 24 when crossing the field ridge, one pin is pulled out, the lower end of the support foot 24 is rotated around the axis of the pin toward the main frame 1, and the support foot 24 is tied to the main frame 1 with a rope to achieve the folding and fixing of the support foot 24. When the support foot 24 is needed, the rope is untied, the lower end of the support foot 24 is rotated away from the main frame 1, and the support foot 24 is made to be in a vertical state. Then the pulled-out pin is inserted back to fix the support foot 24, thereby achieving the state in which the support foot 24 is fully extended relative to the main frame 1. Preferably, a support plate can be provided at the bottom of the support foot 24, and the two ends of the support plate are arc-shaped extending upwards to provide more stable support for the main frame and reduce the resistance during the movement of the rice transplanting device.

[0034] In use, the seedling-throwing device of this application involves placing seedling trays containing seedlings into a placement frame 18 for storage. The main frame 1 is then connected and fixed to a tractor, which tows the device to the field. The operator climbs onto the main frame 1 of the seedling-throwing device, starts the device, and picks up the seedling trays from the placement frame 18, placing them on the seedling tray conveyor belt 7. The conveyor belt 7 transports the seedling trays between the retaining groove 2 and the camshaft 3. Then, the first drive motor 6 drives the camshaft 3 to rotate, causing the protruding part on the side of the camshaft 3 away from the axis of rotation to press against the bottom of the seedling tray, causing the seedlings to be squeezed out of the seedling holes and fall off, thus completing the process. After the extrusion and detachment action, the moving frame 14 drives the extrusion and detachment mechanism to move laterally. The extrusion and detachment mechanism then operates again, repeating the above steps until all the seedlings in the same row on the seedling tray are extruded and detached. Then, the seedling tray is transported by the seedling tray conveyor belt 7 and the drag roller 4, causing the seedling tray to move forward a certain distance. At the same time, the moving frame 14 drives the extrusion and detachment mechanism to move in the opposite direction, and the extrusion and detachment mechanism performs the seedling detachment operation again. The above steps are repeated until all the seedlings in the entire seedling tray are extruded and detached. After the seedling detachment is completed, the seedling tray is transported to the seedling tray outlet 11, and the drag roller 4 transports the seedling tray to the basket 12.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
