Pumpkin planting and seedling raising device

Abstract

This utility model discloses a pumpkin planting and seedling raising device, relating to the field of pumpkin planting technology. The device includes two support frames. A driven shaft is rotatably mounted at the bottom of each support frame. Two discs are fixedly mounted on the outside of the driven shaft. Several support rods are fixedly mounted on the inner side of the discs. Connectors are rotatably mounted on the outside of the support rods. Two crossbars are fixedly mounted at the bottom of each pair of opposite connectors. This utility model, through an intermittent mechanism, allows the drive shaft to drive the drive wheel to rotate. Combined with the interaction between the driven wheel and the boss and U-shaped groove, this enables intermittent rotation of the driven shaft, which in turn drives the discs, support rods, and cultivation trays on the crossbars to rotate periodically. This breaks the limitations of traditional fixed cultivation trays, ensuring that pumpkin seedlings in each cultivation tray receive uniform light, effectively avoiding problems such as excessive growth and weak growth caused by uneven light exposure, and improving the overall growth quality of the seedlings.

Description

Technical Field

[0001] This utility model relates to the field of pumpkin planting technology, specifically a pumpkin planting and seedling raising device. Background Technology

[0002] In the process of pumpkin seedling cultivation, traditional seedling devices generally adopt a fixed cultivation tray structure. This can easily lead to problems such as excessive growth and weak seedlings due to insufficient light. Secondly, the height of the nozzles in the matching sprinkler components is fixed, which cannot adapt to the spraying needs of different seedling stages. If the nozzle height is too high during the seed germination stage, the impact of falling water droplets is too great, which can easily break up the seedling substrate and expose the seeds, thereby reducing the seed germination rate. If the nozzle height is too low, the spraying range is limited, making it difficult to achieve uniform spraying. After entering the true leaf stage, the fixed-height nozzles will also lead to uneven moisture distribution among plants. Some plants will have too much water on their leaves, while others will not be sprayed enough, ultimately resulting in a mixture of strong and weak seedlings, affecting the consistency of seedling cultivation and the survival rate. Utility Model Content

[0003] To address the problems of insufficient light and inability to adjust the height of the spraying mechanism in fixed cultivation trays, the purpose of this invention is to provide a pumpkin planting and seedling raising device.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a pumpkin planting and seedling raising device, including a support frame, of which there are two. A driven shaft is rotatably mounted on the bottom of the support frame. Two discs are fixedly mounted on the outside of the driven shaft. Several support rods are fixedly mounted on the inner side of the discs. Connecting parts are rotatably mounted on the outside of the support rods. Two crossbars are fixedly mounted on the bottom of the connecting parts on each opposite side. Several cultivation trays are provided at the top of the crossbars. An intermittent mechanism is provided at one end of the driven shaft. The intermittent mechanism includes a drive shaft, which is rotatably connected to one of the support frames. The outside of the drive shaft is fixedly mounted on the support frame. The drive shaft is fixedly mounted with a boss, and a drive wheel is fixedly mounted on the outer wall of the drive shaft. A driven wheel that cooperates with the drive wheel is fixedly mounted on the outside of the driven shaft. Several U-shaped grooves that cooperate with the boss are opened on the outside of the driven wheel. The cultivation tray includes a placement box. The interior of the placement box is grid-like. Connecting blocks one are fixedly mounted on both the front and rear sides of the placement box. Several evenly distributed water outlet grooves are opened through the bottom of the placement box. Connecting block two is fixedly mounted on the side of connecting block one away from the placement box. A plug rod is fixedly mounted on the bottom of connecting block one. Several circular grooves that cooperate with the plug rod are opened on the top of the crossbar.

[0005] Preferably, the top of the disc is provided with a spraying mechanism, which includes a mounting plate. A pipe is fixedly mounted on the bottom of the mounting plate, and several evenly distributed atomizing nozzles are fixedly mounted on the bottom of the pipe. The top of the mounting plate is provided with an adjustment mechanism. The adjustment mechanism includes a support plate, which is fixedly connected to a support frame. Two support blocks are slidably mounted on the top of the support plate. L-shaped blocks are rotatably mounted on both sides of the support blocks. Two support blocks are fixedly mounted on the upper surface of the support plate. A drive rod is slidably mounted on the top of the support blocks. Two T-shaped blocks are fixedly mounted on the outside of the drive rod. The T-shaped blocks are slidably connected to the L-shaped blocks by pins. A moving rod is provided on one side of each of the two support blocks, which is slidably connected to the support plate. A connecting block is fixedly mounted on the top of the moving rod. Third, the connecting block three is slidably connected to the L-shaped block via a pin; the end of the drive rod away from the drive wheel is provided with a drive mechanism, which is used to drive the drive rod to move; the drive mechanism includes an operating rod, which is fixedly connected to the drive rod, a slider is fixedly installed at the bottom of the operating rod, a slide rail is slidably installed at the bottom of the slider, one end of the slide rail is fixedly connected to another support frame, an L-shaped frame is fixedly installed at the top of the slider, a spring is fixedly installed on the lower surface of the inner wall of the L-shaped frame, a ring is fixedly installed at the bottom of the spring, an L-shaped rod is fixedly installed in the middle of the round rod, the L-shaped rod is slidably connected to the L-shaped frame, and several slots are opened through the top of the slide rail, which are used in conjunction with the L-shaped rod, and the L-shaped rod is slidably connected to the slider; several anti-slip strips are fixedly installed on the outside of the operating rod.

[0006] Preferably, the top of the support frame has a through groove through which the pipe passes, and the width of the through groove is greater than the diameter of the pipe.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application sets up an intermittent mechanism, in which the drive shaft drives the drive wheel to rotate. With the interaction of the driven wheel, the boss, and the U-shaped groove, the driven shaft can rotate intermittently, thereby driving the disc, the support rod, and the cultivation tray on the cross frame to rotate periodically.

This application includes an adjustment mechanism. When the drive rod is pushed, the T-shaped block drives the L-shaped block to rotate along the support block. At the same time, the moving rod moves along the support plate to realize the height adjustment of the spraying mechanism, which can adapt to the height requirements of pumpkin seedlings at different growth stages and improve the survival rate and overall quality of seedlings.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-10 As shown, this utility model provides a pumpkin planting and seedling raising device, including a support frame 1. There are two support frames 1. A driven shaft 10 is rotatably installed at the bottom of the support frame 1. Two discs 11 are fixedly installed on the outside of the driven shaft 10. Several support rods 12 are fixedly installed on the inner side of the discs 11. Connecting parts 13 are rotatably installed on the outside of the support rods 12. Two cross frames 14 are fixedly installed at the bottom of each opposite side of the connecting parts 13. Several cultivation trays 15 are provided at the top of the cross frames 14. An intermittent mechanism 2 is provided at one end of the driven shaft 10. The intermittent mechanism 2 includes a drive shaft 21, which is rotatably connected to one of the support frames 1. A boss 22 is fixedly installed on the outside of the drive shaft 21, and a drive wheel 23 is fixedly installed on the outer wall of the drive shaft 21. A driven wheel 24 that works with the drive wheel 23 is fixedly installed on the outside of the driven shaft 10. Several U-shaped grooves that work with the boss 22 are opened on the outside of the driven wheel 24. By setting up the intermittent mechanism 2, the drive shaft 21 drives the drive wheel 23 to rotate. With the interaction of the driven wheel 24 with the boss 22 and the U-shaped grooves, the driven shaft 10 can rotate intermittently, which in turn drives the disc 11, the support rod 12 and the cultivation tray 15 on the cross frame 14 to rotate periodically. This breaks the limitations of the traditional fixed cultivation tray 15, so that the pumpkin seedlings in each cultivation tray 15 can receive light evenly, effectively avoiding problems such as excessive growth and weak growth caused by uneven light, and improving the overall growth quality of the seedlings. The drive shaft 21 is driven by a motor and supported by L-shaped support legs.

[0022] The top of the disc 11 is provided with a spraying mechanism 3. The spraying mechanism 3 includes a mounting plate 30. A pipe 31 is fixedly installed on the bottom of the mounting plate 30. Several evenly distributed atomizing nozzles 32 are fixedly installed on the bottom of the pipe 31. The top of the mounting plate 30 is provided with an adjustment mechanism 4. The adjustment mechanism 4 includes a support plate 40, which is fixedly connected to the support frame 1. Two support blocks 41 are slidably installed on the top of the support plate 40. L-shaped blocks 42 are rotatably installed on both sides of the support blocks 41. Two support blocks 43 are fixedly installed on the upper surface of the support plate 40. A drive rod 44 is slidably installed on the top of the support blocks 43. Two T-shaped blocks 45 are fixedly installed on the outside of the drive rod 44. The T-shaped blocks 45 are slidably connected to the L-shaped blocks 42 through pins. A moving rod 46 is provided on one side of each of the two support blocks 41 and is slidably connected to the support plate 40. A connecting block 47 is fixedly installed on the top of the moving rod 46 and is slidably connected to the L-shaped blocks 42 through pins. A drive mechanism 5 is provided at the end of the drive rod 44 away from the drive wheel 23. The drive mechanism 5 is used to drive the drive rod 44 to move. By setting the adjustment mechanism 4, when the drive rod 44 is pushed, the T-shaped block 45 drives the L-shaped block 42 to rotate along the support block 41. At the same time, the moving rod 46 moves along the support plate 40 to realize the height adjustment of the spraying mechanism 3, which can adapt to the plant height requirements of different growth stages of pumpkin seedlings and improve the survival rate and overall quality of seedlings.

[0023] The cultivation tray 15 includes a placement box 150, the interior of which is grid-shaped. Connecting blocks 151 are fixedly installed on both the front and rear sides of the placement box 150. Several evenly distributed water outlet channels are opened through the bottom of the placement box 150.

[0024] Connecting block 151 is fixedly installed on the side away from the placement box 150. Connecting block 153 is used to facilitate the removal of the placement box 150 from the crossbar 14.

[0025] The bottom end of the connecting block 151 is fixedly installed with a plug rod 154, and the top end of the cross frame 14 is provided with several round grooves 155 that cooperate with the plug rod 154. By setting the plug rod 154 and the round grooves 155, the positioning and installation of the cultivation tray 15 and the cross frame 14 can be quickly realized. Disassembly is simple and it is convenient to clean, replace and perform other maintenance operations on the cultivation tray 15.

[0026] A through groove 48 is provided on the top of the support frame 1, through which the pipe 31 passes. The width of the through groove 48 is greater than the diameter of the pipe 31. By setting the through groove 48, sufficient space is provided for the pipe 31 to move, ensuring that the pipe 31 is not affected by the support frame 1 when the adjustment mechanism 4 drives the pipe 31 to adjust its position, thus ensuring the smooth realization of the adjustment function of the spray mechanism 3.

[0027] The drive mechanism 5 includes an operating lever 50, which is fixedly connected to a drive rod 44. A slider 51 is fixedly installed at the bottom of the operating lever 50, and a slide rail 52 is slidably installed at the bottom of the slider 51. One end of the slide rail 52 is fixedly connected to another support frame 1. An L-shaped frame 53 is fixedly installed at the top of the slider 51. A spring 54 is fixedly installed on the lower surface of the inner wall of the L-shaped frame 53. A ring is fixedly installed at the bottom of the spring 54. An L-shaped rod 55 is fixedly installed in the middle of the round rod and is slidably connected to the L-shaped frame 53. Several slots 56 are opened through the top of the slide rail 52. The slots 56 are used in conjunction with the L-shaped rod 55. The L-shaped rod 55 is slidably connected to the slider 51. By setting the drive mechanism 5, pulling or pushing the operating lever 50 drives the slider 51 to move along the slide rail 52, thereby driving the drive rod 44 to move. Then, the L-shaped rod 55 is inserted into the slot 56 to fix the slider 51. The other end of the slide rail 52 is fixed by a support leg.

[0028] Several anti-slip strips are fixedly installed on the outside of the operating lever 50. By setting the anti-slip strips, the friction between the hand and the operating lever 50 is increased, making it easier for the operator to push, reducing the difficulty of operation and improving the adjustment efficiency.

[0029] Working principle: In actual use, connect one end of the external water pipe to the pipe 31, then fill the pumpkin seedling substrate into the grid inside the placement box 150 of the cultivation tray 15, then align the insertion rod 154 with the round groove 155 at the top of the horizontal frame 14 and insert it to realize the installation between the cultivation tray 15 and the horizontal frame 14. If it is necessary to remove or maintain the cultivation tray 15, the placement box 150 can be lifted off the horizontal frame 14 through the connecting block 2 153. When the seedlings are exposed to light, the motor is started to drive the drive shaft 21 to rotate, which drives the drive wheel 23 and the boss 22 to rotate synchronously. The drive wheel 23 meshes with the driven wheel 24 for transmission. At the same time, the boss 22 periodically embeds into the U-shaped groove of the driven wheel 24, driving the driven shaft 10 to rotate intermittently. The driven shaft 10 drives the two discs 11 to rotate. The discs 11 drive the cross frame 14 and the cultivation tray 15 to rotate periodically through the support rod 12 and the connector 13, so that the seedlings in each cultivation tray 15 can receive light evenly. When adjusting the spray height according to the needs of different stages of pumpkin seedling cultivation, pull the L-shaped rod 55 upward, the spring 54 is compressed, the L-shaped rod 55 disengages from the slot 56 of the slide rail 52, push or pull the operating rod 50 to drive the slider 51 to move along the slide rail 52, and then drive the drive rod 44 to slide on the second support block 43. The drive rod 44 pushes the L-shaped block 42 to rotate around the first support block 41 through the T-shaped block 45. The L-shaped block 42 drives the moving rod 46 to slide along the support plate 40, and simultaneously drives the mounting plate 30, pipe 31, and atomizing nozzle 32 to move until the atomizing nozzle 32 is adjusted to a suitable position. Then release the L-shaped rod 55, the spring 54 returns to its original position and pushes the L-shaped rod 55 into the corresponding slot 56 to complete the height fixation. When watering, the external water pump is started, so that the water flows through the pipe 31 to each atomizing nozzle 32. The atomizing nozzle 32 refines the water flow into a mist and sprays it evenly on the seedlings.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
