Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a drop-seedling fixing device. Background Technology

[0002] In rice cultivation, seedlings are typically raised in seedling trays and then transplanted. Traditional rice transplanting relies heavily on manual labor, resulting in low efficiency and high labor intensity. With technological advancements, automated rice transplanting equipment has emerged. For example, utility model patent CN217985962U discloses a self-falling rice transplanting structure, including a screw, a fixed base for driving the screw's forward and reverse rotation, a guide rail parallel to the screw, a slider sliding along the guide rail, a telescopic mechanism, and a crossbar. The crossbar has several clamping mechanisms interspersed for picking up and placing seedlings. One end of the telescopic mechanism is connected to the crossbar, and the other end is connected to the slider. The telescopic mechanism controls the crossbar to move back and forth along the Y-axis, while the screw controls the slider and telescopic mechanism to move back and forth along the X-axis. In use, the clamping mechanisms clamp the seedlings, and after clamping, the telescopic mechanism retracts, releasing the seedlings into the field, completing the transplanting process. However, when this seedling throwing structure is used, the seedlings need to be clamped by a clamping mechanism and pulled out of the seedling tray. This makes it easy to damage the seedlings during the pulling process, resulting in a longer recovery and greening period after transplanting. Summary of the Invention

[0009] The drive mechanism includes a drive rod and a push-pull structure. The middle part of the drive rod is rotatably connected to the frame, and one end of the drive rod is provided with a handle. The other end is hinged to the insertion rod frame via a ball joint. The push-pull structure includes a push-pull plate and a drive assembly for driving the push-pull plate to move longitudinally back and forth. One end of the push-pull plate is fixedly connected to the mounting frame. The two sides of the push-pull plate are respectively provided with serrated pushing and pulling parts at the front and rear ends. Limit blocks are also provided on both sides of the push-pull plate. The drive assembly includes a drive seat and a swing rod mounted on the drive seat. The push plate and two shift rods are slidably engaged with the drive base and can move vertically up and down relative to the frame. The top of the drive base is hinged to the end of the drive rod near the handle. The middle part of the swing rod is rotatably connected to the drive base. One end of each of the two push plates is rotatably connected to the drive base. The other ends of the two push plates are respectively engaged with the push part and the pull part. The two ends of the swing rod are respectively connected to the two push plates through traction lines. The two shift rods are movably and vertically inserted into the drive base.

[0010] Preferably, a first guide rod is provided on the frame along the longitudinal direction, and a first guide block is provided at the bottom of the mounting frame to slide in cooperation with the first guide rod.

[0011] Preferably, the top of the mounting frame is provided with a second guide block, and the bottom of the seedling tray frame is provided with a second guide rod that slides and engages with the second guide block.

[0012] Preferably, the seedling tray frame is provided with limiting grooves that slide and engage with the two side edges of the seedling tray, and one end of the limiting groove is provided with a stop bar to limit one section of the seedling tray, and the other end of the limiting groove is movably provided with a locking piece to limit the other end of the seedling tray.

During the transplanting process, the inserting rod is inserted from the bottom of the seedling tray hole to push the seedling out of the seedling tray hole. The inserting rod does not contact the seedling, effectively avoiding damage to the seedling during the transplanting process. When operating, the operator drives the drive rod to rotate by the handle, which can drive the inserting rod frame to move downward, so that the inserting rod on the inserting rod frame can insert into the bottom of the seedling tray hole, thereby causing the seedling to fall out of the seedling tray hole and be inserted into the field. At the same time, as the drive rod drives the inserting rod frame to move upward, the drive mechanism can drive the seedling tray frame to move longitudinally along the limiting guide rail. When the limiting rod moves to the guide part at the end of the limiting rail, the limiting rod can move along the guide part to another adjacent limiting rail, thereby driving the seedling tray frame to move laterally to realize the alternation of seedlings. In this way, the inserting rod can insert into all the seedling tray holes and realize the equal-distance dropping of seedlings. The structure is simple and the operation is convenient.

[0029] like Figures 1 to 5 As shown, this application discloses a drop-seedling fixing device, including a frame 1, a seedling tray frame 6, a seedling tray 8, a planting pole frame 10, and a drive mechanism, specifically:

[0030] The frame 1 is a square frame structure welded from metal profiles. The frame 1 is equipped with a mounting bracket 2 and a limiting plate 3. The mounting bracket 2 is slidably engaged with the frame 1 and can move back and forth longitudinally relative to the frame 1. The limiting plate 3 is horizontally fixedly installed on the frame 1. The limiting plate 3 has several transversely arranged limiting rails 4. The limiting rails 4 extend longitudinally, and the ends of two adjacent limiting rails 4 are connected by an inclined guide part 5 to form a circular, curved, spiraling rail. Preferably, a handrail bracket 32 ​​can be installed at the front end of the frame 1 so that the operator can pull or push the seedling dropping device through the handrail bracket 32.

[0031] The seedling tray frame 6 is slidably mounted on the mounting frame 2 and can move laterally to the left and right relative to the frame 1. A limiting rod 7 that slides with the limiting rail 4 is detachably mounted on the seedling tray frame 6. Specifically, the limiting rod 7 can be installed on the seedling tray frame 6 by plugging it in, so as to facilitate the installation and removal of the limiting rod 7.

[0032] The seedling tray 8 is placed upside down on the seedling tray frame 6, and the seedling tray 8 is provided with several seedling tray holes 9 arranged in a longitudinal and transverse manner;

[0033] The pole frame 10 includes a frame body 11 and a plurality of poles 12 installed on the frame body 11. The frame body 11 is slidably engaged with the machine frame 1 and can move up and down relative to the seedling tray frame 6.

[0034] The drive mechanism includes a drive rod 13 and a push-pull structure. The middle part of the drive rod 13 is rotatably connected to the frame 1, and one end of the drive rod 13 is provided with a handle 14. The other end is hinged to the insertion rod frame 10 through a ball joint 15. The push-pull structure includes a push-pull plate 16 and a drive assembly that drives the push-pull plate 16 to move longitudinally back and forth. One end of the push-pull plate 16 is fixedly connected to the mounting frame 2. The two sides of the push-pull plate 16 are respectively provided with a serrated pushing part 17 and a pulling part 18 at the front and rear ends. Limiting blocks 19 are also provided on both sides of the push-pull plate 16. The drive assembly includes a drive seat 20, and a swing rod 21, two push plates 22 and two shifting rods 23 mounted on the drive seat 20. The drive seat 20 is slidably engaged with the frame 1 and can move up and down relative to the frame 1 in the vertical direction. The top of the drive seat 20 is hinged to the end of the drive rod 13 near the handle 14. The middle part of the swing rod 21 is connected to the drive seat 20 through a rotating shaft. The two push plates 22 are rotatably connected, with one end of each push plate 22 rotatably connected to the drive seat 20 via a rotating shaft. The other ends of the two push plates 22 are respectively engaged with the push part 17 and the pull part 18. The two ends of the swing rod 21 are respectively connected to the two push plates 22 via traction lines 24. The two shift rods 23 are movably and vertically inserted into the drive seat 20, and the upper ends of the two shift rods 23 are respectively hinged to the two ends of the swing rod 21. The lower ends of the two shift rods 23 can respectively abut against the two limit blocks 19. When the shift rods 23 move up and down relative to the drive seat 20, the shift rods 23 can drive the swing rod 21 to rotate, so that one end of the swing rod 21 moves upward and the other end moves downward, thereby causing the ends of the two push plates 22 to swing up and down alternately. When one push plate 22 is engaged with the push part 17, the other push plate 22 is separated from the pull part 18. When one push plate 22 is separated from the push part 17, the other push plate 22 can engage with the pull part 18.

[0035] The present invention provides a seedling-planting device that places a seedling tray frame 6 upside down on top of the seedling tray frame 6. During transplanting, the inserting rod 12 pushes the seedling out of the seedling tray hole 9 from the bottom of the seedling tray hole 9 without contacting the seedling, effectively avoiding damage to the seedling during transplanting. During operation, the operator rotates the drive rod 13 by using the handle 14, which moves the inserting rod frame 10 downwards, causing the inserting rod 12 on the inserting rod frame 10 to push the seedling out of the seedling tray hole 9 from the bottom of the seedling tray hole 9 and fall into the field. Simultaneously, as the drive rod 13 drives the insertion rod frame 10 to move upward, the drive mechanism can drive the seedling tray frame 6 to move longitudinally along the limiting guide rail to realize the longitudinal change of the seedling tray. When the limiting rod 7 moves to the guide part 5 at the end of the limiting track 4, the limiting rod 7 can move along the guide part 5 to another adjacent limiting track 4, thereby driving the seedling tray frame 6 to move laterally to realize the lateral change of the seedlings. This allows the insertion rod 12 to insert into all the seedling tray holes 9 in the seedling tray 8 and realize the equal-distance seedling dropping. The structure is simple and the operation is convenient.

[0036] Specifically, in use, the seedling tray 8 is placed upside down on the seedling tray frame 6. The operator holds the handle 14. When the handle 14 is lifted upwards, it drives the insertion rod frame 10 to move downwards, causing the insertion rod 12 on the insertion rod frame 10 to insert into the bottom of the seedling tray hole 9, thereby achieving automatic seedling placement. Then, the handle 14 is pressed downwards to drive the insertion rod frame 10 to move upwards, causing the insertion rod 12 to separate from the seedling tray 8. During the downward pressing process, the handle 14 drives the drive seat 20 to move downwards, thereby driving the push plate. 22 moves downwards, with the end of one push plate 22 engaging with the teeth on the pusher 17. During the downward movement of the push plate 22, it pushes the push-pull plate 16, causing the seedling tray frame 6 to move towards the rear of the frame 1. This causes the limiting rod 7 to move from the starting end to the end of the limiting track 4, thereby achieving automatic longitudinal relocation of the seedling tray 8. This moves the other row of seedlings on the seedling tray 8 that has not yet been lowered to below the insertion rod 12. When the limiting rod 7 reaches the end of the limiting track 4, it can move along the guide part 5... The seedling tray 8 moves to the adjacent limit track 4, thereby driving the seedling tray 8 to automatically change laterally. The limit block 19 located on one side of the push unit 17 can move to below the shifting rod 23 that it cooperates with. During the downward movement of the drive seat 20, the limit block 19 limits the shifting rod 23, preventing the shifting rod 23 from moving downward. This causes the shifting rod 23 to move upward relative to the drive seat 20, thereby driving the swing rod 21 to rotate. At this time, one end of the swing rod 21 moves upward and drives the push unit 17 through the traction line 24. The push plate 22 moves upward, causing its end to separate from the push part 17, while the other end of the swing rod 21 moves downward, causing the other push plate 22 to swing downward under its own weight without being pulled by the swing rod 21, until its end engages with the pull part 18, thereby realizing the interchange of the two push plates 22. That is, when one push plate 22 engages with the push part 17, the other push plate 22 separates from the pull part 18, and when one push plate 22 separates from the push part 17, the other push plate 22 engages with the pull part 18.

[0037] In this application, five seedling trays 8 are arranged horizontally on the seedling tray frame 6. Each seedling tray 8 has 16 rows of seedling tray holes 9 arranged horizontally, and each row of seedling tray holes 9 has 30 holes arranged vertically. A set of insertion rods 12 is provided on the insertion rod frame 10 corresponding to each seedling tray 8. Each set of insertion rods 12 has two rows arranged horizontally, and each row has three insertion rods arranged vertically. Eight limiting guide rails are arranged horizontally. The pushing part 17 and the pulling part 18 are each provided with nine teeth, so that when the limiting rod 7 moves from the starting end of the first limiting guide rail 4 to the end of the last limiting guide rail 4, the insertion rod 12 can insert into all the seedling tray holes 9. After all the seedlings in the seedling tray 8 have been lowered, the lowering lever 21 can be used to move the insertion rod frame 10 to its highest position. Then, the limiting rod 7 can be removed from the mounting frame 2. The mounting frame 2 and the seedling tray frame 6 can be manually pushed to the starting position, and then a new seedling tray 8 can be replaced to carry out the subsequent seedling lowering operation.

[0038] In one embodiment of this application, a first guide rod 25 may be arranged longitudinally on the frame 1, and a first guide block 26 is arranged at the bottom of the mounting frame 2. The first guide block 26 is provided with a sliding hole, and the mounting frame 2 and the frame 1 are slidably engaged through the sliding hole with the first guide rod 25.

[0039] Preferably, the top of the mounting frame 2 may also be provided with a second guide block 27, and the bottom of the seedling tray frame 6 is provided with a second guide rod 28 that slides in cooperation with the second guide block 27.

[0040] In another embodiment of this application, the seedling tray frame 6 is provided with limiting grooves 29 that slide with the two side edges of the seedling tray 8. One end of the limiting groove 29 is provided with a stop bar 30 that limits one section of the seedling tray 8. The other end of the limiting groove 29 is movably provided with a locking piece 31 that limits the other end of the seedling tray 8. The locking piece 31 is rotatably mounted on the seedling tray frame 6. After inserting both sides of the seedling tray 8 into the limiting groove 29, the seedling tray 8 is pushed so that one end of the seedling tray 8 abuts against the stop bar 30. Then, by rotating the locking piece 31, the locking piece 31 abuts against the other end of the seedling tray 8, thereby locking and fixing the seedling tray 8 on the seedling tray frame 6 to improve the stability of the seedling tray 8.

[0041] In one specific embodiment, the frame 1 is provided with two parallel third guide blocks 33, which are vertically fixed on the frame 1. The third guide blocks 33 are provided with sliding holes along their length direction. The mounting rod bracket 10 is provided with two third guide rods 34, which are slidably engaged with the two sliding holes, thereby realizing the sliding engagement between the mounting rod bracket 10 and the frame 1.

[0042] In another specific embodiment, two fourth guide rods 35 are vertically arranged on the frame 1, and the two sides of the drive seat 20 are respectively slidably engaged with the two fourth guide rods 35 to realize the sliding engagement between the drive seat 20 and the frame 1.

[0043] To improve the stability of the push-pull plate 16 movement, a fifth guide rod 36 is provided on the frame 1 along the longitudinal direction, and a connecting block 37 that slides with the fifth guide rod 36 is provided on the push-pull plate 16.

[0044] In one preferred embodiment of this application, balance bars 38 are symmetrically arranged on both sides of the bottom of the frame 1 to ensure the stability of the frame 1 during movement.

[0045] Furthermore, a sliding plate 39 can be provided at the bottom of the frame 1. The front end of the sliding plate 39 extends upward with an arc-shaped guide surface 40. The sliding plate is flat, which can further increase the contact area between the frame 1 and the paddy field, thereby further improving the stability of the frame 1's movement and preventing the frame 1 from sinking into the mud. In addition, by providing an arc-shaped guide surface 40 at the front end of the sliding plate, the resistance during the movement of the frame 1 can be reduced.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of the technical solutions of the present invention.
