Description

Technical Field

[0001] This utility model relates to the field of crop planting technology, and more specifically, to a rice breeding device. Background Technology

[0002] Rice breeding equipment is a device that can sow and germinate seeds. Seeds are sown into a breeding tray and then germinated at a constant temperature. After the seeds germinate and grow to the stage where they can be transplanted, they are removed from the breeding tray and transplanted to a designated location. By selecting seeds in advance and germinating them at a constant temperature, an excellent development environment is provided for the seedlings before transplanting, which can greatly improve the efficiency of seedling raising and the survival rate of seedlings.

[0003] When sowing seeds into a seedling tray, a specified number of seeds need to be sown in the planting holes of the tray so that the seeds can grow in the planting holes. However, there are many planting holes with small diameters, so it is easy for the number of seeds to vary too much or for seeds to be sown outside the planting holes during the sowing process. This can lead to overcrowding of seedlings, which can affect their development. Sowing seeds outside the planting holes will also result in a waste of seeds. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rice breeding device to solve the problems of excessively large differences in the number of seeds and sowing outside the planting hole during the sowing process.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A rice breeding device includes a breeding rack, supporting crossbars, and breeding trays. Four breeding racks are arranged in pairs, with multiple supporting crossbars fixedly connected between two breeding racks. Multiple breeding trays are respectively mounted on multiple sets of supporting crossbars. A sowing mechanism is disposed on the surface of the breeding racks. The sowing mechanism includes two top crossbars fixedly connected to the tops of the two sets of breeding racks. A guide rod is fixedly connected between the two top crossbars. A connecting frame is slidably fitted onto the surface of the guide rod. The connecting frame has a U-shaped cross-section. Multiple seed boxes are fixedly connected to the two longitudinal arm ends of the connecting frame. A cover plate is provided on the top of each seed box. Multiple shielding plates are fixedly connected between the two sets of breeding racks. Multiple sowing holes are opened on the surface of each shielding plate. Multiple sowing nozzles are provided on the lower surface of each seed box.

[0007] Furthermore, the number of sowing holes is the same as the number of planting holes on the breeding tray and corresponds one-to-one.

[0008] Furthermore, a screw is rotatably connected between the two top crossbars, and the screw is threaded into the top of the connecting frame. A first motor is fixedly connected to the surface of one of the top crossbars, and the output shaft of the first motor is fixedly connected to one end of the screw.

[0009] Furthermore, the bottom of the seed box is connected to multiple cloth tubes, and the multiple sowing nozzles are respectively connected to the lower ends of the multiple cloth tubes.

[0010] Furthermore, a second motor is fixedly connected to the bottom of the seed box, and a rotating shaft is fixedly connected to the output shaft of the second motor. Multiple rotating wheels are fixedly connected to the surface of the rotating shaft, and protrusions are fixedly connected to the surface of each of the multiple rotating wheels. A stop bar is fixedly connected to the surface of the seeding nozzle.

[0011] Furthermore, a leveling spring is fixedly connected between the seed box and the sowing nozzle.

[0012] Furthermore, the sling tube is located inside the balancing spring.

[0013] Furthermore, a guide column is fixedly connected to the lower surface of the seed box, and a guide rail is fixedly connected to the upper surface of the seeding nozzle. The lower end of the guide column is slidably connected to the inside of the guide rail.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this scheme, when the sowing nozzle is aligned with the sowing hole, the seeds fall through the sowing hole into the planting hole on the breeding tray. When the sowing nozzle is removed from the sowing hole, the seeds stop falling. Therefore, it can be achieved that sowing is only done when the sowing nozzle is aligned with the planting hole, which improves the uniformity of the sowing quantity and the accuracy of sowing, and prevents the seedlings from growing too crowded and sparse, affecting their development and causing seeds to be wasted by being sown outside the planting hole.

[0016] (2) When sowing, the second motor drives the rotating wheel to rotate, so that the protrusion on the rotating wheel repeatedly contacts the surface of the baffle, pushing the baffle to move and causing the sowing nozzle to repeatedly shift and shake, which can prevent the seeds from getting blocked during the falling process, improve the sowing smoothness, and avoid seed blockage that leads to overcrowding or sparse seedlings.

[0024] 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.

[0025] Please see Figures 1-5A rice breeding device includes a breeding rack 1, supporting crossbars 2, and breeding trays 3. Four breeding racks 1 are arranged in pairs, and multiple supporting crossbars 2 are fixedly connected between two breeding racks 1. Multiple breeding trays 3 are respectively arranged on multiple sets of supporting crossbars 2. A sowing mechanism is disposed on the surface of the breeding rack 1. The sowing mechanism includes two top crossbars 405 fixedly connected to the tops of the two sets of breeding racks 1. A guide rod 404 is fixedly connected between the two top crossbars 405. A connecting frame 402 is slidably sleeved on the surface of the guide rod 404. The connecting frame 402 has a U-shaped cross-section, and multiple crossbars are fixedly connected to the two longitudinal arm ends of the connecting frame 402. A seed box 403 is provided with a cover plate 409 on the top. Multiple shielding plates 401 are fixedly connected between the two sets of breeding racks 1. Multiple sowing holes 408 are opened on the surface of the shielding plates 401. Multiple sowing nozzles 410 are provided on the lower surface of the seed box 403. The number of sowing holes 408 is the same as the number of planting holes on the breeding tray 3 and corresponds one-to-one. A screw 406 is rotatably connected between the two top crossbars 405. The screw 406 is threaded into the top of the connecting frame 402. A first motor 407 is fixedly connected to the surface of one of the top crossbars 405. The output shaft of the first motor 407 is fixedly connected to one end of the screw 406.

[0026] The seed box 403 has multiple cloth-covering tubes 417 connected to its bottom end, and multiple sowing nozzles 410 are respectively connected to the lower ends of the multiple cloth-covering tubes 417. A second motor 416 is fixedly connected to the bottom end of the seed box 403. A rotating shaft 413 is fixedly connected to the output shaft of the second motor 416. Multiple rotating wheels 414 are fixedly connected to the surface of the rotating shaft 413. Protrusions 415 are fixedly connected to the surface of each of the multiple rotating wheels 414. A stop bar 412 is fixedly connected to the surface of the sowing nozzle 410. A leveling spring 411 is fixedly connected between the seed box 403 and the sowing nozzle 410. The cloth-covering tubes 417 are located inside the leveling spring 411. A guide column 419 is fixedly connected to the lower surface of the seed box 403. A guide rail 418 is fixedly connected to the upper surface of the sowing nozzle 410. The lower end of the guide column 419 is slidably connected to the interior of the guide rail 418.

[0027] By adopting the above technical solution, when sowing seeds, rice seeds are loaded into seed boxes 403, and then the first motor 407 is started. The first motor 407 drives the screw 406 to rotate, which in turn drives the connecting frame 402 and multiple seed boxes 403 to move at a uniform speed. Since the surface of the sowing nozzle 410 is in contact with the surface of the blocking plate 401, when the sowing nozzle 410 moves to align with the sowing hole 408, the seeds in the seed box 403 pass through the sowing hole 408 and fall into the planting hole on the breeding tray 3. As the seed box 403 continues to move, the sowing nozzle 410 disengages from the sowing hole 408 and is blocked by the blocking plate 401, preventing the seeds from falling further. Therefore, sowing can be achieved only when the sowing nozzle 410 is aligned with the planting hole, which improves the uniformity of sowing quantity and the accuracy of sowing, and prevents the seedlings from growing too crowded or sparsely, affecting their development, and preventing seeds from being wasted due to sowing outside the planting hole.

[0028] During sowing, the second motor 416 drives the rotating shaft 413 to rotate, which in turn drives the rotating wheel 414 to rotate. This causes the protrusion 415 on the rotating wheel 414 to repeatedly contact the surface of the stop bar 412, pushing the stop bar 412 to move. This causes the sowing nozzle 410 to deviate. Then, the straightening spring 411 drives the sowing nozzle 410 back to its original position. This repetition causes the sowing nozzle 410 to vibrate, preventing blockage during seed descent. The cooperation between the guide column 419 and the guide rail 418 ensures that the sowing nozzle 410 can only move along the trajectory specified by the guide rail 418, thus preventing severe deviation of the sowing nozzle 410 during vibration and ensuring accurate sowing.

[0029] Instructions for use: First, put the rice seeds into the seed box 403;

[0030] Next, the first motor 407 drives the connecting frame 402 and multiple seed boxes 403 to move at a constant speed.

[0031] At the same time, the second motor 416 causes the protrusion 415 on the rotating wheel 414 to repeatedly contact the surface of the stop bar 412, causing the seeding nozzle 410 to deflect.

[0032] Finally, the seed nozzle 410 falls as it passes through the seeding hole 408 and stops when it leaves the seeding hole 408, thus achieving seed sowing.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
