[0015] The present invention has the following beneficial effects: 1. In the transplanting device for rice planting, when the slide seat slides along the guide rail, the slide seat drives the scraper plate to move along the seedling tray, so that the scraper plate can level the soil on the seedling tray, which is beneficial to the subsequent transplanting and growth of rice seeds. At the same time, when the slide seat moves, it drives the slide bar to slide along the slide groove, and the slide bar drives the sliding protrusion to slide inside the wavy groove, so that the sliding protrusion can drive the slide bar to reciprocate left and right, and the slide bar drives the slide plate to reciprocate left and right in the moving groove, and the slide plate drives the scraper plate to reciprocate left and right, so that the scraper plate levels the soil on the seedling tray, and the left and right reciprocating motion of the scraper plate can conveniently discharge the scraped excess soil from both sides, avoiding excessive soil accumulation in the middle of the scraper plate to affect the movement of the scraper plate.

[0016] 2. In the transplanting device for rice planting, when the sliding rod reciprocates left and right, the first resistance member is driven to reciprocate left and right through the transmission rod, the first resistance member is in conflict with the second resistance member, driving the second resistance member to reciprocate up and down, the second resistance member drives the movable rod and the driving rod to reciprocate up and down, the driving rod drives the lower pressing plate and the compacting block to reciprocate up and down, through the downward movement of the compacting block, the rice seeds can be pressed into the soil inside the seedling tray, so that the rice seeds can better enter the soil, which is beneficial to the growth of the rice seeds, and at the same time, through the up and down reciprocating movement of the compacting block, the upper surface of the soil inside the seedling tray can be patted, making the soil softer, thereby making it easier for the rice seeds to enter the soil, further improving the planting quality.

[0017] 3. In the transplanting device for rice planting, when the movable rod and the driving rod reciprocate up and down, air is inflated into the compacting block through the air cylinder, so that the compacting block can maintain an expanded state when moving downward, so that the bottom of the compacting block is flat, thereby facilitating the pressing and beating of the soil inside the seedling tray, and air is sucked from the inside of the compacting block through the air cylinder, so that the compacting block is in a deflated state when moving upward, thereby reducing the adsorption force between the compacting block and the soil surface, thereby reducing the possibility of the compacting block sucking out the soil when moving upward.

[0018] 4. In the transplanting device for rice planting, when the compacting block presses the soil, the knocking column knocks the inclined block, causing the lower pressure plate to vibrate and transmit the vibration to the soil, so that the soil inside the seedling tray becomes softer after pressing. At the same time, the knocking of the knocking column causes the lower pressure plate to reciprocate left and right by an end distance, so that it is more convenient for rice seeds to enter the soil, further improving the transplanting effect of rice seeds.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1-Figure 13 A rice planting transplanting device comprises a guide rail 1 arranged on a field, a slide seat 2 is slidably arranged on the guide rail 1, a transplanting box 3 is fixed on the upper surface of the slide seat 2, a feeding hopper 4 is arranged on the top of the transplanting box 3, and a feeding port 5 is arranged at the bottom of the transplanting box 3; A side plate 6 is fixed to one side of the guide rail 1, and a slide groove 7 is provided on the inner surface of the side plate 6. A slide rod 8 is slidably provided in the slide groove 7. The slide rod 8 is slidably connected to the transplanting box 3. The other end of the slide rod 8 is transmission-connected to a slide plate 9. A moving groove 10 for the slide plate 9 to slide is provided at the bottom of the transplanting box 3. A scraping plate 11 for leveling the seedling tray is fixed to the bottom of the slide plate 9; A wave-shaped groove 12 is formed on the inner wall of the slide groove 7 , and a sliding protrusion 13 is fixed to the end of the slide rod 8 . The sliding protrusion 13 is slidably disposed in the wave-shaped groove 12 .

[0034] In the technical scheme, when transplanting rice seeds, the rice seeds are first fed into the transplanting box 3 through the feed hopper 4, and then the seeds are evenly planted on the soil of the seedling tray through the feed port 5. The feed port 5 can evenly sow the seeds, and a servo motor can be provided on the slide 2, and the servo motor drives the slide 2 to slide on the guide rail 1. The above technologies are all prior arts, not the innovation of the present application, and will not be described in detail. When the slide 2 moves along the guide rail 1, the slide 2 first drives the scraper plate 11 to move along the upper surface of the seedling tray, so that the scraper plate 11 levels the soil on the seedling tray, which is convenient for the subsequent transplanting and planting of the rice seedlings. At the same time, the slide 2 drives the transplanting box 3 to move, and the transplanting box 3 drives the slide bar 8 to slide along the slide groove 7, and the slide bar 8 drives the sliding protrusion 13 to slide inside the wave-shaped groove 12. When the sliding protrusion 13 slides along the wave-shaped groove 12, the sliding protrusion 13 reciprocates left and right, and the sliding protrusion 13 reciprocates left and right to drive the slide plate 9 to reciprocate left and right in the moving groove 10. The plate 9 drives the scraping plate 11 to reciprocate left and right, so that the scraping plate 11 moves back and forth left and right along the upper surface of the seedling tray. Through the reciprocating left and right motion, during leveling, the excess soil can be conveniently moved along the direction of the scraping plate 11 to both sides of the scraping plate 11, so as to facilitate the discharge of the scraped soil. The scraping side of the scraping plate 11 is set to an arc surface structure. Through the arc surface structure, the middle position of the scraping plate 11 is raised outward, so as to further facilitate the guidance of the soil, and facilitate the discharge of the soil from both sides of the scraping plate 11, so as to avoid the accumulation of soil in the middle position of the scraping plate 11 during leveling.

[0035] In the second embodiment, when the rice seeds are transplanted to the seedling tray, the rice seeds may not fully enter the soil because they are evenly sprinkled on the soil of the seedling tray through the feeding port 5, which is not conducive to the growth of the rice seeds. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 13A transmission rod 14 is fixed on the circumference of the slide bar 8, and the transmission rod 14 is slidably arranged in the transplanting box 3. An adjustment seat 15 is fixed inside the transplanting box 3. The other end of the transmission rod 14 is slidably arranged in the adjustment seat 15. A positioning plate 16 is arranged below the adjustment seat 15. A lower pressing plate 17 is elastically arranged below the positioning plate 16. A plurality of groups of compacting blocks 31 are fixed to the lower surface of the lower pressing plate 17; A first resistance member 18 is fixed to the end of the transmission rod 14, a driving rod 19 is provided on the upper surface of the lower pressure plate 17, the driving rod 19 passes through the positioning plate 16 and is elastically connected to the positioning plate 16, a movable rod 20 is provided on the top of the driving rod 19, and a second resistance member 21 in contact with the first resistance member 18 is fixed to the top of the movable rod 20.

[0036] In this technical solution, if Figure 6 and Fig. 9 As shown, when the slide bar 8 moves to the right, it drives the transmission rod 14 to move to the right, and the transmission rod 14 moves to the right, driving the first resistance member 18 to move to the right, and the first resistance member 18 moves to the right to resist the second resistance member 21, prompting the second resistance member 21 to move downward, and the second resistance member 21 moves downward to drive the movable rod 20 and the driving rod 19 to move downward, and the driving rod 19 moves downward to drive the lower pressure plate 17 to move downward, and the lower pressure plate 17 drives several groups of compacting blocks 31 to move downward, so that the several groups of compacting blocks 31 press the soil on the seedling tray downward, so that the rice seeds can better enter the soil; when the slide bar 8 moves to the left, it drives the transmission rod 14 to reset, and the reset of the transmission rod 14 drives the first resistance member 18 and the second resistance member 21 to reset, so that the driving rod 19 and the movable rod 20 drive the lower pressure plate 17 to move upward and reset.

[0037] Embodiment 3: When the compacting block 31 is used for pressing, the bottom surface of the compacting block 31 will generate an adsorption force with the surface of the soil, so that when the compacting block 31 moves upward, the resistance is relatively large. In serious cases, the soil may be sucked out, making the soil no longer flat. To address this problem, this embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 13 A cavity 22 is provided inside the driving rod 19, a limit plate 23 is fixed to the bottom end of the movable rod 20, the limit plate 23 is slidably disposed in the cavity 22, and the movable rod 20 is slidably connected to the driving rod 19; A first horizontal plate 24 is fixed to one side of the movable rod 20, an air cylinder 25 is fixed to the outer surface of the driving rod 19, a piston plate 26 is slidably arranged in the air cylinder 25, a connecting rod 27 is fixed between the piston plate 26 and the first horizontal plate 24, a first spring 28 is sleeved on the outer side of the connecting rod 27, a venting groove 29 is opened inside the lower pressing plate 17, an air guide pipe 30 is connected between the air cylinder 25 and the venting groove 29, and the tops of several groups of compacting blocks 31 are all connected to the venting groove 29; A second horizontal plate 32 is fixed to one side of the movable rod 20, a third abutment member 33 is fixed to the lower surface of the second horizontal plate 32, a first limiting rod 34 is slidably provided inside the positioning plate 16, a first limiting groove 35 is provided on the outer surface of the driving rod 19, a fourth abutment member 36 is fixed to the first limiting rod 34, a slideway 37 is provided on the positioning plate 16 for the fourth abutment member 36 to slide, and a second spring 38 is fixed between the first limiting rod 34 and the inner wall of the positioning plate 16; A receiving groove 39 is provided inside the positioning plate 16, and a third cross plate 41 is slidably provided inside the receiving groove 39. One end of the third cross plate 41 is fixedly connected to the driving rod 19, and a third spring 42 is fixed to the other end of the third cross plate 41. A clamping block 55 is provided at the end of the third cross plate 41. A contraction groove 56 for the sliding of the clamping block 55 is provided in the third cross plate 41, and a sixth spring 57 is fixed between the clamping block 55 and the contraction groove 56. A clamping groove 58 for inserting the clamping block 55 is provided on the inner wall of the receiving groove 39.

[0038] In the present technical solution, when the second abutment 21 moves downward, the movable rod 20 is first driven to move downward, and the movable rod 20 drives the limit plate 23 to slide inside the cavity 22, and the first limit rod 34 is inserted into the first limit groove 35 to limit the drive rod 19, so that the drive rod 19 does not move first, and when the movable rod 20 moves downward, it drives the first transverse plate 24 to move downward, and the first transverse plate 24 moves downward to compress the first spring 28, and the first spring 28 accumulates force, and at the same time, the first transverse plate 24 drives the connecting rod 27 to move downward, and the connecting rod 27 drives the piston plate 26 to slide downward in the cylinder 25. The gas in the air cylinder 25 is input into the vent groove 29 through the air guide pipe 30, and then filled into the compacting block 31 through the vent groove 29, so that the compacting block 31 expands. The compacting block 31 adopts a hard rubber structure. After being inflated, the appearance is a square columnar structure. The bottoms of several groups of compacting blocks 31 form a complete plane structure. After the compacting block 31 is filled with air, the movable rod 20 continues to move downward, and the movable rod 20 drives the second cross plate 32 to move downward. The second cross plate 32 drives the third abutment 33 to move downward, and the third abutment 33 abuts against the fourth abutment 36. Fig.11As shown, the first limiting rod 34 is prompted to move to the left, the second spring 38 is compressed and stored, the first limiting rod 34 is removed from the first limiting groove 35, and the restriction on the driving rod 19 is released. At this time, the limiting plate 23 contacts the cavity 22, so that the driving rod 19 and the movable rod 20 move synchronously, thereby driving the lower pressing plate 17 to move downward, so that the compacting block 31 presses and beats the surface of the soil; when the first resisting member 18 moves to the left, the second resisting member 21 loses the resistance of the first resisting member 18, and the first spring 28 releases force, so that the first cross plate 24 moves upward, and the upward movement of the first cross plate 24 drives the connecting rod 27 and the piston plate 26 to move upward, and the gas inside the compacting block 31 is sucked into the air cylinder 25 through the ventilation groove 29 and the air guide pipe 30, so that the compacting block 31 becomes deflated (as shown in FIG. Fig. 9 The first spring 28 is pressed against the first horizontal plate 24 and the first horizontal plate 24 is pressed against the first horizontal plate 24. The first spring 28 is pressed against the first horizontal plate 24 and the first horizontal plate 24 is pressed against the first horizontal plate 24. When the first cross plate 24 drives the movable rod 20 to continue to move upward, it will drive the driving rod 19 to move upward, and the driving rod 19 will drive the lower pressure plate 17 to move upward, and the lower pressure plate 17 will drive the compacting block 31 to move upward and reset. By setting the end of the first limiting rod 34 to a sloped structure, when the driving rod 19 moves upward to reset, it can contact the cross-section of the first limiting rod 34, so that the first limiting rod 34 can be reset, so that after the driving rod 19 is reset, the first limiting rod 34 can be inserted into the first limiting groove 35 again.

[0039] In the present technical solution, when the first limiting rod 34 is removed from the first limiting groove 35, that is, when the driving rod 19 is released from the limit, the third spring 42 and the third cross plate 41 are provided, and the third spring 42 is used to support the third cross plate 41, so that the driving rod 19 will not fall due to gravity, and can only be driven to move downward by the movable rod 20; when the movable rod 20 drives the driving rod 19 downward, the driving rod 19 drives the third cross plate 41 to move downward. At this time, the third cross plate 41 compresses the third spring 42 downward, so that the third spring 42 is compressed and stored until the driving rod 19 drives the compacting block 31 to cover the soil. At this time, the third cross plate 41 drives the clamping block 55 to move to the clamping groove 58. The sixth spring 57 releases force, and the block 55 is bounced into the slot 58, thereby restricting the third cross plate 41; then, when resetting, since the third cross plate 41 is restricted by the block 55 and the slot 58, in the absence of a large external force, the third cross plate 41 will not move, and the driving rod 19 will not move either, so that the movable rod 20 will first move upward with the driving rod 19. When the limit plate 23 conflicts with the cavity 22, the driving rod 19 is subjected to an upward force. By setting the end face of the block 55 as an inclined structure, the driving rod 19 is subjected to a large upward force, which can slide the block 55 out of the slot 58, so that the block 55 is recovered into the contraction groove 56, compressing the sixth spring 57, and releasing the restriction of the third cross plate 41.

[0040] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3. For details, please refer to Figure 1-Figure 13 A knocking column 43 is fixed to the bottom end of the third spring 42, a sleeve 44 is fixed to the lower surface of the positioning plate 16, the knocking column 43 is slidably arranged in the sleeve 44, a fifth abutment 45 is fixed to the lower surface of the third cross plate 41, a fixing block 46 is fixed inside the accommodating groove 39, a second limiting rod 47 is slidably arranged on the fixing block 46, a second limiting groove 48 is opened on the surface of the knocking column 43, a sixth abutment 49 is fixed to the second limiting rod 47, and a fifth spring 50 is fixed between the second limiting rod 47 and the inner wall of the accommodating groove 39; A slanted block 51 that contacts the knocking column 43 is fixed to the upper surface of the lower pressure plate 17 , a boss 52 is fixed to the upper surface of the lower pressure plate 17 , a guide groove 53 for the driving rod 19 to slide is formed on the boss 52 , and a fourth spring 54 is fixed between one side of the driving rod 19 and the inner wall of the boss 52 .

[0041] In the present technical solution, when the third horizontal plate 41 moves downward to insert the card block 55 into the card slot 58, the knocking column 43 is restricted by the second limiting rod 47, so that the knocking column 43 does not move, so that the third spring 42 is compressed and stored. When the third horizontal plate 41 moves downward to drive the card block 55 to insert into the card slot 58, the third horizontal plate 41 drives the fifth abutment 45 downward to abut against the sixth abutment 49, so that the second limiting rod 47 moves rightward and compresses the fifth spring 50 (such as Fig.12 As shown in the figure, the second limiting rod 47 is moved out of the second limiting groove 48 to release the restriction on the knocking column 43. At this time, the third spring 42 releases the force, and the knocking column 43 is instantly released, so that the knocking column 43 moves downward, and the inertia of the knocking column 43 when moving downward is used to knock the inclined block 51. The knocking can make the soil inside the seedling tray softer after being pressed. Fig. 9 As shown, when the knocking column 43 knocks the inclined block 51, it contacts the inclined block 51. Since the lower pressing plate 17 is slidably connected to the bottom end of the driving rod 19, the lower pressing plate 17 can move a short distance to the right, so that the lower pressing plate 17 drives the convex seat 52 to move to the right, and the fourth spring 54 is compressed and stored. The lower pressing plate 17 moves to the right and drives the compacting block 31 to move a short distance to the right. After the knocking is completed, the fourth spring 54 is reset, so that the lower pressing plate 17 moves to the left and resets. Through the left and right movement of the lower pressing plate 17, it is convenient for the rice seeds to fully enter the soil; when the driving rod 19 is reset upward, it drives the lower pressing plate 17 and the third cross plate 41 to reset upward, and the lower pressing plate 17 resets upward and drives the knocking column 43 to move upward and reset; In the present technical solution, by setting the end face of the second limiting rod 47 as a sloped structure, the knocking column 43 can resist the slope of the knocking column 43 during the upward movement, so that the second limiting rod 47 can be reset without getting stuck; the bottom end of the driving rod 19 is engaged in the boss 52, so that the driving rod 19 can only move horizontally in the boss 52 and cannot move up and down, and the bottom end of the air guide tube 30 is sealed and connected to the ventilation groove 29 by a rubber sheet, and the rubber sheet can slide left and right in the lower pressure plate 17 when the lower pressure plate 17 moves left and right, thereby not affecting the connection between the air guide tube 30 and the ventilation groove 29, and no air leakage will occur.
