Description

Technical Field

[0001] This utility model belongs to the field of rice seedling technology, and in particular, a rice seedling device. Background Technology

[0002] Rice is an important food crop belonging to the genus Oryza of the family Poaceae. Rice cultivation is a very complex process. Unlike most other crops, rice cultivation requires first cultivating seedlings and then transplanting them into paddy fields. Currently, most seedling raising devices do not have quantitative measuring devices, which leads to situations where there are too many or too few rice seeds in different areas when sowing through funnels, thus affecting the cultivation effect of rice seeds.

[0003] A Chinese patent (authorization announcement number CN216982771U) discloses a rice seedling transplanter, which "includes a seedling frame and partitions, the partitions are evenly arranged inside the seedling frame, and the top two sides of the seedling frame are provided with sliding grooves, the sliding grooves are slidably connected with sliding rods inside the sliding grooves, and funnels and first connecting rods are evenly arranged between the two sliding rods."

[0004] It is evident that the cited patent document has the problem of potentially having too many or too few rice seeds sown. Utility Model Content

[0005] The purpose of this invention is to provide a rice seedling raising device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice seedling raising device, including a seedling box, with mounting blocks welded to both sides of the seedling box, sliders on the top surfaces of the two mounting blocks, and connecting blocks welded to the top surfaces of the two sliders. A plurality of filling hoppers for storing rice seeds are equidistantly connected to the top surface of the connecting block. A rotating shaft is rotatably connected to the inner wall of the connecting block via a pin. A material holding block is fixedly sleeved on the periphery of the rotating shaft. A plurality of feeding troughs for holding rice seeds are equidistantly opened on the periphery of the material holding block. A plurality of discharge ports for discharging rice seeds are equidistantly opened on the bottom surface of the connecting block. A gear is connected to one end of the rotating shaft through the connecting block. A plurality of racks meshing with the gear are equidistantly arranged on the top surface of one of the mounting blocks. A limiting component for restricting the rotation of the gear is installed on the top surface of the connecting block and one side of the racks.

[0007] Preferably, the top surface of the connecting block is welded with an inclined L-shaped bracket, and the limiting component includes a pad, a locking block, two vertical rods, and multiple abutment blocks.

[0008] Preferably, the pad is disposed between the bracket and the gear, the locking block is welded to the bottom surface of the pad, and the locking block is tapered.

[0009] Preferably, both vertical rods are connected and fixed to the top surface of the pad, and the free ends of both vertical rods extend through to the top of the bracket.

[0010] Preferably, the plurality of abutments are respectively connected and fixed to one side of the rack, and the top surfaces of the plurality of abutments and the bottom surfaces of the pads are all inclined.

[0011] Preferably, the top surfaces of both mounting blocks are welded with slide rails for limiting the position of the sliders, and the two sliders are respectively slidably sleeved on the periphery of the two slide rails.

[0012] Preferably, a guide rail for limiting the position of multiple racks is welded to the top surface of one of the mounting blocks, and the multiple racks are slidably sleeved on the periphery of the guide rail.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This rice seedling raising device, by pushing the connecting block, can provide power for the movement of the gear, so that the gear can move along the rack. When the gear moves along the rack, it can provide power for the rotation of the gear, thereby allowing the rice seeds entering the feed trough to rotate to the discharge port and be discharged. Compared with the existing device for sowing rice seeds, this device can quantitatively measure the amount of rice seeds sown, reducing the possibility of too many or too few rice seeds in different areas after sowing.

[0015] By setting the limiting components, the gears can be restricted to prevent rotation when they are not needed, thus allowing rice seeds to be sown earlier. The welded slide rails can limit the movement of the two sliders, while the welded guide rails can limit multiple racks and allow the racks to move along the guide rails, thereby changing the spacing between rice seeds during sowing.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The rice seedling raising device shown includes a seedling box 1, the inner cavity of which is filled with soil for planting rice seeds. Mounting blocks 2 are welded to both sides of the seedling box 1. Slider blocks 3 are provided on the top surface of the two mounting blocks 2. Connecting blocks 4 are welded to the top surface of the two sliders 3. Several filling hoppers 5 for storing rice seeds are equidistantly connected to the top surface of the connecting blocks 4. The rice seeds to be sown can be put into the multiple filling hoppers 5.

[0028] The inner wall of the connecting block 4 is rotatably connected to a rotating shaft 6 via a pin. A material holding block 7 is fixedly sleeved around the circumference of the rotating shaft 6. Several feeding troughs 8 for holding rice seeds are equidistantly opened around the circumference of the material holding block 7. Several discharge ports 9 for discharging rice seeds are equidistantly opened on the bottom surface of the connecting block 4. In the initial state, the feeding troughs 8 are directly below the filling hopper 5, so that the rice seeds in the filling hopper 5 will fall into the feeding troughs 8 and fill them. When sowing is required, the operator pushes the connecting block 4 and rotates the rotating shaft 6, so that the rotating shaft 6 can drive the material holding block 7 to rotate, so that... The feed block 7 can rotate some rice seeds through the feed trough 8. After the feed block 7 rotates 90 degrees, the rice seeds will pass through the discharge port 9 and be sown in the soil in the seedling box 1. Continuing to rotate the shaft 6 will allow the feed block 7 to rotate 90 degrees again, so that the feed trough 8 is below the filling hopper 5, and the feed trough 8 will be filled with rice seeds again. By repeating the operation, rice seeds can be sown in a quantitative manner, avoiding the situation where there are more or less rice seeds in different areas after sowing, thus improving the effect of rice seed cultivation.

[0029] One end of the rotating shaft 6 passes through the connecting block 4 and is connected to a gear 10. Several racks 11 that mesh with the gear 10 are equidistantly arranged on the top surface of one of the mounting blocks 2. When the operator pushes the connecting block 4, the rotating shaft 6 drives the gear 10 to move, allowing the gear 10 to move to one side of the rack 11 and move along the rack 11, thereby rotating the gear 10. This, in turn, drives the material holding block 7 to rotate, so that rice seeds can be sown. After the material holding block 7 has rotated 360 degrees, the gear 10 will disengage from the rack 11 and move to the next rack 11, causing the material holding block 7 to rotate 360 ​​degrees again. This allows the operator to achieve quantitative sowing of rice seeds simply by moving the connecting block 4.

[0030] A limiting component for restricting the rotation of gear 10 is installed on the top surface of connecting block 4 and one side of rack 11. An inclined L-shaped bracket 12 is welded to the top surface of connecting block 4. The limiting component includes a pad 13, a locking block 14, two vertical rods 15, and multiple abutments 16. The pad 13 is located between the bracket 12 and gear 10. The locking block 14 is welded to the bottom surface of the pad 13 and is tapered. Both vertical rods 15 are connected and fixed to the top surface of the pad 13, and the free ends of both vertical rods 15 extend through to the top of the bracket 12. Multiple abutments 16 are connected and fixed to one side of rack 11. The two sides of the top surface of multiple abutments 16 and the two sides of the bottom surface of pad 13 are inclined, and one side of pad 13 extends to one side of abutment 16. In the initial state, the locking block 14 will be locked in the tooth gap around the gear 10 to fix the gear 10 and prevent it from rotating during movement when the teeth are not needed. When the gear 10 rotates, it generates rotation. Before the gear 10 moves to one side of the rack 11 and moves along the rack 11, the abutment block 16 will first abut against the pad block 13. At this time, as it continues to move, the pad block 13 can move upward through the inclined surface on one side of the abutment block 16, so that the pad block 13 can drive the locking block 14 to move upward. After the locking block 14 moves upward, it will be removed from the tooth gap around the gear 10, thus releasing the fixation of the gear 10, allowing the gear 10 to rotate along the rack 11. After the gear 10 moves away from the rack 11, the pad block 13 will move away from one side of the abutment block 16. After the pad block 13 moves away, it will move downward due to its own weight, thus allowing the locking block 14 to lock into the tooth gap around the gear 10 again, thereby fixing the gear 10 and preventing it from rotating during the movement when it does not need to rotate, which would lead to premature sowing of rice seeds.

[0031] When the pad block 13 drives the locking block 14 to move longitudinally, the pad block 13 will drive the two vertical rods 15 to move longitudinally. Since the free ends of the two vertical rods 15 extend through the top of the bracket 12, the two vertical rods 15 can limit the movement of the pad block 13 and the locking block 14 to prevent the pad block 13 and the locking block 14 from shifting.

[0032] One of the mounting blocks 2 has a guide rail 18 welded to its top surface to limit the position of multiple racks 11. Several racks 11 are slidably sleeved on the periphery of the guide rail 18. The multiple racks 11 can move on the periphery of the guide rail 18, so that the spacing between the multiple racks 11 can be adjusted as needed, thereby changing the spacing between the sown rice seeds. Each abutment block 16 and one of the mounting blocks 2 have screw holes on one side. The two screw holes on one side of each abutment block 16 and the one side of the mounting block 2 are threaded with bolts, which can fix the racks 11 after the position is adjusted, thereby adjusting the spacing between the sown rice seeds.

[0033] The top surfaces of the two mounting blocks 2 are welded with slide rails 17 for limiting the position of the sliders 3, and the two sliders 3 are respectively slidably sleeved on the periphery of the two slide rails 17.

[0034] Working principle:

[0035] This rice seedling raising device places rice seeds into multiple filling hoppers 5. Since the filling hoppers 5 are connected to a connecting block 4, the rice seeds in the filling hoppers 5 fall into the feeding troughs 8 around the holding block 7, filling the feeding troughs 8. At this point, a person pushes the connecting block 4, which drives the gear 10 via the rotating shaft 6. The gear 10 moves to one side of the rack 11 and moves along the rack 11, causing the gear 10 to rotate. As the gear 10 rotates, it drives the holding block 7 to rotate via the rotating shaft 6, which in turn drives some of the rice seeds to rotate via the feeding troughs 8. After the holding block 7 rotates 90 degrees, the rice seeds pass through the discharge port 9 and can be sown in the soil inside the seedling box 1. Continuing to move the device, the holding block 7 rotates 90 degrees again, so that the feeding trough 8 is positioned below the filling hoppers 5, allowing for further sowing. The rice seeds are filled in once, and the process is repeated to sow a fixed amount of rice seeds. In the initial state, the locking block 14 is locked in the tooth gap around the gear 10. Before the gear 10 moves to the side of the rack 11 and moves along the rack 11, the abutment block 16 will first abut against the pad block 13. As it continues to move, the pad block 13 can move upward along the inclined surface of the abutment block 16. When the pad block 13 moves upward, it will drive the locking block 14 to be removed from the tooth gap around the gear 10, thus releasing the fixation of the gear 10. After the gear 10 is removed from the rack 11, the pad block 13 will move away from the side of the abutment block 16. After the pad block 13 is removed, it will move downward due to its own weight, thus locking the locking block 14 in the tooth gap around the gear 10 again, thereby fixing the gear 10 and preventing it from rotating during the movement when it does not need to rotate, which would lead to premature sowing of rice seeds.
