Technical Field

[0001] This utility model relates to the field of agricultural planting machinery technology, and in particular to a multi-row hard disk-type 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 at least one of the technical problems mentioned above, and provides a multi-row hard disk-type seedling throwing device that can effectively avoid damage to seedlings during the throwing process and improve the survival rate of seedlings.

[0024] like Figure 1 and Figure 2 As shown, this application discloses a multi-row hard disk-type seedling throwing device, including a main frame 1, a seedling tray conveying mechanism, a seedling throwing mechanism, and a seedling tray recovery mechanism, specifically:

[0025] The seedling tray conveying mechanism includes a drive shaft 2, a driven shaft 3, a conveyor belt 4, and a drive motor 5 that is connected to the drive shaft 2. Multiple drive wheels 6 are arranged on the drive shaft 2 along its axial direction, and multiple driven wheels 7 that correspond one-to-one with the drive wheels 6 are arranged on the driven shaft 3 along its axial direction. Each set of corresponding drive wheels 6 and driven wheels 7 is connected to the conveyor belt 4.

[0026] The seedling removal mechanism includes a mounting frame 8 fixedly installed above the seedling tray conveying mechanism, and a removal assembly mounted on the mounting frame 8. The removal assembly includes a removal frame 9 and a first drive cylinder 10. The first drive cylinder 10 is connected to the removal frame 9 and can drive the removal frame 9 to move vertically relative to the mounting frame 8. Multiple striking pins 11 are arranged along the length of the removal frame 9. The seedling tray used in this application is a rigid seedling tray with through-holes at the top and bottom of the tray openings. Figure 3As shown, when cultivating seedlings using the seedling tray of this application: First, spread the rigid seedling tray (face up) on a flat, hardened long surface; second, cover it with paddy soil (fine soil or thin mud); third, hand-sow the selected seeds (dried) that have been soaked for 24 hours into the soil in the holes, and then cover it with soil again; fourth, keep the soil in the holes moist, and after about 12-15 days, the seedlings will grow to about 12-15cm tall (the entire tray will be full); fifth, before transplanting the seedlings, use a shovel to remove the roots at the bottom of the seedling tray (the roots of the tray grow in a tangled pattern). Because the soil has a certain degree of stickiness, and the small raised rings designed inside the holes provide a certain degree of support, as long as it is not very dry, the seedlings will not easily fall out of the seedling holes in a short time due to the adhesion.

[0027] The seedling tray recycling mechanism includes a seedling tray recycling frame 12 that is fixedly installed on the edge of the main frame 1.

[0028] This utility model discloses a multi-row hard disk-type seedling throwing device, which includes a seedling tray conveying mechanism, a seedling throwing mechanism, and a seedling tray recycling mechanism. The seedling tray conveying mechanism transports the seedlings to the area below the seedling throwing mechanism. Then, the first drive cylinder 10 drives the throwing frame 9 to move towards the seedling tray, causing the striking pin 11 to poke the bottom of the seedling tray, thereby pushing the seedlings out of the seedling holes in the seedling tray to achieve seedling throwing. After the seedlings are thrown, the seedling tray is transported to the seedling tray recycling mechanism for unified collection and processing. In the entire operation, no manual seedling throwing is required, the degree of automation is high, the seedling throwing efficiency is improved, and the seedlings are not damaged during the seedling throwing process, thus improving the seedling survival rate.

[0029] In this application, the mounting frame 8 is provided with sliding grooves 13 on both sides, and the drop frame 9 is provided with sliders 14 on both sides that slide in cooperation with the two sliding grooves 13 respectively. By setting the sliders 14 to slide in cooperation with the sliding grooves 13, the stability of the drop frame 9 movement is improved.

[0030] In one preferred embodiment of this application, a movable frame 15 is provided on the main frame 1, and a seedling tray conveying mechanism is installed on the movable frame 15. The movable frame 15 is connected to a second drive cylinder 16 that drives it to move laterally relative to the main frame 1. In this application, the number of impact pins 11 is less than the number of holes in each row of seedling trays. Therefore, the second drive cylinder 16 is used to drive the movable frame 15 to move laterally, and after each movement, the bottom of the seedling tray is pierced. Through multiple lateral movements, until all the holes in a whole row of seedling trays are pierced, the seedling tray is then conveyed forward by the seedling tray conveying mechanism, so that the impact pins 11 squeeze the holes in another row of seedling trays. The above steps are repeated until the holes in the entire seedling tray are pierced.

[0031] Furthermore, a guide rail 17 is provided on the main frame 1 along the direction perpendicular to the seedling tray conveying, and a roller 18 that cooperates with the guide rail 17 is provided at the bottom of the movable frame 15. Through the rolling cooperation between the roller 18 and the guide rail 17, the movement of the movable frame 15 can be limited, so that the movable frame 15 maintains stable lateral movement.

[0032] In another preferred embodiment of this application, in order to facilitate the storage of seedling trays, a plurality of placement frames 19 for storing seedling trays are installed on the main frame 11. The placement frames 19 are open-top frames and are fixedly installed on the side edge of the main frame 1.

[0033] In a more preferred embodiment of this application, the conveyor belt 4 is provided with a limiting block 20 for limiting the end and side of the seedling tray, so that the seedling tray can be accurately positioned when placed and the seedling tray can be prevented from moving relative to the conveyor belt 4 during the conveying process.

[0034] Furthermore, several support shafts 21 are provided between the drive shaft 2 and the driven shaft 3. Support wheels 22 are provided on the support shafts 21. The two ends of the support shafts 21 are rotatably connected to the main frame 1 through bearings. The support wheels 22 support the conveyor belt 4 to prevent the seedling trays from collapsing downwards after they are placed on the conveyor belt 4, thereby ensuring that the seedling trays can be transported horizontally.

[0035] In this application, a support foot 23 is provided at the bottom of the main frame 1 to provide support for the main frame 1. The support foot 23 can be unfolded and folded relative to the main frame 1. Specifically, the upper end of the support foot 23 is connected to the main frame 1 by two pins. When the vehicle needs to fold the support foot 23 when crossing the field ridge, one pin is pulled out, the lower end of the support foot 23 is rotated around the axis of the pin toward the main frame 1, and the support foot 23 is tied to the main frame 1 with a rope to achieve the folding and fixing of the support foot 23. When the support foot 23 needs to be used, the rope is untied, the lower end of the support foot 23 is rotated away from the main frame 1, and the support foot 23 is made to be in a vertical state. Then the pulled-out pin is inserted back to fix the support foot 23, thereby achieving the fully unfolded state of the support foot 23 relative to the main frame 1. Preferably, a support plate can be provided at the bottom of the support foot 23, 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.

[0036] In use, the seedling-throwing device of this application involves placing a seedling tray containing seedlings into a placement frame 19 for storage. Then, the main frame 1 is connected to a tractor, which tows the seedling-throwing device to the field. The operator climbs onto the main frame 11 of the seedling-throwing device, starts the device, picks up the seedling tray from the placement frame 19, and places it upside down onto the conveyor belt 4. The conveyor belt 4 transports the seedling tray directly below the seedling-dropping mechanism. Then, the second drive cylinder 16 drives the dropping frame 9 towards the seedling tray, causing the striking pin 11 to pierce the bottom of the seedling tray, thus allowing the seedlings to... After the seedlings are removed from the seedling holes, the moving frame 15 moves the seedling conveying mechanism laterally, and the seedling removal mechanism operates again. This process is repeated until all the seedlings in the same row on the seedling tray are removed. Then, the seedling tray is conveyed to the seedling tray by the seedling tray conveying mechanism, causing the seedling tray to move forward a certain distance. At the same time, the moving frame 15 moves the seedling tray conveying mechanism in the opposite direction, and the seedling removal mechanism performs the seedling removal operation again. This process is repeated until all the seedlings in the entire seedling tray are removed. After the seedling removal is completed, the seedling tray is transported to the seedling tray recycling mechanism for unified recycling and processing.

[0037] 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.
