Description

Technical Field

[0001] The utility model relates to the field of rice cultivation, in particular to a cultivation device used for rice planting. Background Art

[0002] Rice cultivation first requires seed selection. When choosing rice seeds, you need to consider the characteristics of the variety and the local climatic conditions. Generally speaking, it is more appropriate to choose varieties with strong disease resistance, high yield and strong adaptability. At the same time, you also need to pay attention to the quality of the seeds to ensure that they have a high germination rate and grow healthily.

[0003] The next step is seedling cultivation, which includes selecting suitable varieties, cultivating seedlings, and controlling temperature and moisture management. Seedling cultivation is usually carried out indoors or in a greenhouse to promote the growth of seedlings by artificially simulating the natural environment.

[0004] After waiting for the seedlings to be raised, they need to be transplanted. When the seedlings grow to a certain size, they will be transplanted into the rice fields. The time for transplanting is generally in spring or autumn. The specific time depends on the local climate. When transplanting, pay attention to maintaining appropriate spacing to ensure sufficient ventilation and sunlight between the rice. At the same time, pay attention to avoid excessive crowding that may lead to the occurrence of diseases and insect pests.

[0005] Traditionally, when raising seedlings, the selected seeds are often sown manually on the rice seedling bed. This method relies entirely on manual sowing, and the density of the seeds cannot be controlled. It is easy to cause the seeds to be too dense, which leads to a decrease in the seed germination rate, and even causes 20%-30% of the seeds to be wasted, resulting in increased costs and a waste of good rice seeds.

[0006] Therefore, it is necessary to propose a cultivation device for rice planting to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model provides Figure 1-Figure 11 The cultivation device for rice planting shown in the figure comprises a storage shell 1, a sowing port 12 is fixedly installed on the bottom surface of the storage shell 1, and the sowing port 12 is communicated with the interior of the storage shell 1, a distributing roller 2 is rotatably installed on the bottom end of the interior of the storage shell 1, and a plurality of evenly distributed distributing grooves 21 are provided on the distributing roller 2, and the shape of the distributing groove 21 is crescent-shaped, and the direction of the crescent bending is the same as the direction of rotation of the distributing roller 2, a handle 7 is fixedly installed on one side of the exterior of the storage shell 1, and an opening is provided on the top of the storage shell 1. When in use, the selected rice seeds are placed in the interior of the storage shell 1, and the rice seeds will be placed under the influence of gravity. The rice seeds are driven into the interior of the dividing trough 21. When the dividing roller 2 rotates, the dividing trough 21 will rotate to be connected with the sowing port 12, and then the rice seeds inside the dividing trough 21 will slide out from the sowing port 12 driven by gravity. It should be noted that the two ends of the dividing roller 2 are tightly fitted with the inner wall of the storage shell 1, and the side wall of the dividing roller 2 is tightly fitted with the bottom inner wall of the storage shell 1, so that the rice seeds will not leak out from the gap. The crescent shape can make the rice seeds inside the dividing trough 21 slowly leak out from the inside of the dividing trough 21, preventing all the rice seeds from leaking out at once, so that the rice seeds can be more evenly distributed on the seedbed.

[0033] The first central axis 3 is rotatably clamped inside the material distribution roller 2, first rotation grooves 11 are provided on both sides of the storage shell 1, wheels 6 are provided on both sides of the outer surface of the storage shell 1 corresponding to the first rotation grooves 11, the two ends of the first central axis 3 are rotatably clamped inside the two first rotation grooves 11, a plurality of second clamping plates 32 are installed on the outer surface of the first central axis 3, a plurality of first clamping grooves 25 used in conjunction with the second clamping plates 32 are provided inside the material distribution roller 2, a matching cylinder 23 is rotatably clamped at both ends of the material distribution roller 2, and a plurality of evenly distributed first clamping plates 24 are fixedly installed on the outside of the matching cylinder 23 The matching cylinder 23 is fixedly installed on the inner side wall of the storage shell 1, and a plurality of first clamping blocks 22 used in conjunction with the first clamping plate 24 are fixedly installed at both ends of the dividing roller 2. The direction of the first clamping plate 24 is opposite to that of the second clamping plate 32, so that the dividing roller 2 can only rotate in one direction. A plurality of retreat grooves 31 corresponding to the second clamping plate 32 are opened on the surface of the first central axis 3, and the second clamping plate 32 is hinged inside the retreat groove 31. A plurality of first springs 33 are embedded in the retreat groove 31, and the ends of the first springs 33 are fixedly installed on the lower surface of the second clamping plate 32.

[0034] In actual use, the handle 7 is held to push the device forward, and the wheel 6 rotates due to friction with the ground, thereby driving the first central axis 3 to rotate in the positive direction. Figure 6 At this time, the second clamping plate 32 will be clamped into the inside of the first clamping groove 25, so that the first central axis 3 cannot rotate inside the material distribution roller 2. At this time, the positive rotation of the first central axis 3 will drive the material distribution roller 2 to rotate positively inside the storage shell 1. When the material distribution roller 2 rotates positively, the first clamping plate 24 is deformed and rotates positively at the end of the material distribution roller 2. When the handle 7 is held and the device is pulled backward, it is seen that Figure 5 At this time, the first clamping plate 24 cooperates with the first clamping block 22 to stop the distribution roller 2 from rotating, and the second clamping plate 32 will enter the inside of the retreat groove 31 under the push of the first clamping groove 25, so that the first central axis 3 can rotate inside the distribution roller 2 to prevent the rice seeds from spilling out when pulling; when in use, it is only necessary to hold the handle 7 to control the device to move back and forth on the seedling bed, so that the rice seeds can be evenly sown on the seedling tray, and the sown seeds are clearly layered to form a layered structure. The layered structure sowing can make the rice seeds more evenly distributed in the seedling bed, avoid the seeds being too dense or sparse, which is beneficial to the growth and development of rice in the seedling stage, and the layered structure sowing is beneficial to the ventilation and light transmission between the rice plants, reduce the occurrence of diseases and insect pests, and also help to improve the photosynthesis efficiency of rice and promote the growth of rice. The layered structure sowing makes the rice plants neat and consistent, which is convenient for farmers to fertilize, irrigate and other field management operations, reduce labor intensity, improve efficiency, and the layered distribution is more convenient for later sales and machine planting operations.

[0035] The first central axis 3 is internally rotated with a second central axis 5, one end of the second central axis 5 is provided with a limiting component 4, the limiting component 4 is used to control the linkage between the material distribution roller 2 and the first central axis 3, a plurality of evenly distributed winding wheels 51 are fixedly mounted on the second central axis 5, a wire rope 52 is wound around the winding wheel 51, the wire rope 52 passes through the first central axis 3 and is fixedly connected to the corresponding second clamping plate 32.

[0036] The first central axis 3 is fixedly installed between the two wheels 6, and the limiting component 4 includes a mounting plate 41, a connecting column 42 is fixedly installed on one side of the mounting plate 41, and sliding rods 43 are slidably clamped on the upper and lower sides of the connecting column 42, and a circular plate 45 is fixedly installed on the end of the sliding rod 43 away from the connecting column 42, and the end of the sliding rod 43 away from the connecting column 42 passes through and is slidably clamped on the mounting plate 41, and a plurality of evenly distributed second springs 44 are fixedly installed between the sliding rod 43 and the connecting column 42, a cross slot 61 is opened in the middle of one of the wheels 6, and the connecting column 42 is rotatably clamped in the middle of the cross slot 61, and the mounting plate 41 is located on the side of the wheel 6 away from the storage shell 1, and the sliding rod 43 is slidably clamped inside the cross slot 61.

[0037] When raising seedlings, there are often many seedbeds in a greenhouse, and each seedbed needs to be sown. When transferring the seedbeds, in order to prevent the leakage of rice seeds caused by the rotation of the dividing roller 2 during movement, a limiting component 4 is provided. When a seedbed is sown, the two circular plates 45 are pinched down, and the slide bar 43 will detach from the inside of the cross slot 61 and enter the inside of the connecting column 42, so that the connecting column 42 can rotate inside the cross slot 61. When the circular plate 45 is released, the slide bar 43 will be pushed by the second spring 44 to clamp the cross slot 61, so that the connecting column 42 cannot rotate. When the column 42 rotates, it will drive the second central axis 5 to rotate, and the rotation of the second central axis 5 will drive the winding wheel 51 thereon to rotate, and the rotation of the winding wheel 51 will reel in the wire rope 52, so that the second clamping plate 32 is pulled into the interior of the retreat groove 31, so that the first central axis 3 can rotate in any direction inside the dividing roller 2. Due to the friction between the dividing roller 2 itself and the inner wall of the storage shell 1 and the push between the first clamping plate 24 and the first clamping block 22, the dividing roller 2 itself will not rotate, thereby preventing the leakage of rice seeds during movement. The second clamping plate 32 can be released and retracted by only pressing and then rotating, which is easy to operate.

[0038] Working principle: During actual use, the selected rice seeds are placed inside the storage shell 1, and the rice seeds enter the inside of the dividing trough 21 driven by gravity. When the dividing roller 2 rotates, the dividing trough 21 rotates to be connected with the sowing port 12, and then the rice seeds inside the dividing trough 21 slide out from the sowing port 12 driven by gravity. It should be noted that the two ends of the dividing roller 2 are tightly fitted with the inner wall of the storage shell 1, and the side wall of the dividing roller 2 is tightly fitted with the bottom inner wall of the storage shell 1, so that the rice seeds will not leak out from the gap. The crescent shape can make the rice seeds inside the dividing trough 21 leak out slowly from the inside of the dividing trough 21, preventing all of them from leaking out at once, so that the rice seeds can be more evenly distributed on the seedbed. Hold the handle 7 and push the device forward. At this time, the wheel 6 rotates due to the friction with the ground, thereby driving the first central axis 3 to rotate forward. Figure 6 At this time, the second clamping plate 32 will be clamped into the inside of the first clamping groove 25, so that the first central axis 3 cannot rotate inside the material distribution roller 2. At this time, the positive rotation of the first central axis 3 will drive the material distribution roller 2 to rotate positively inside the storage shell 1. When the material distribution roller 2 rotates positively, the first clamping plate 24 is deformed and rotates positively at the end of the material distribution roller 2. When the handle 7 is held and the device is pulled backward, it is seen that Figure 5 At this time, the first clamping plate 24 cooperates with the first clamping block 22 to stop the distribution roller 2 from rotating, and the second clamping plate 32 enters the inside of the retreat groove 31 under the push of the first clamping groove 25, so that the first central axis 3 can rotate inside the distribution roller 2 to prevent the rice seeds from spilling out when pulling; when using, only the handle 7 is held to control the device to move back and forth on the seedling bed, so that the rice seeds can be evenly sown on the seedling tray;

[0039] When a seedbed is sown, the two circular plates 45 are pinched down, and the slide bar 43 will disengage from the inside of the cross slot 61 and enter the inside of the connecting column 42, so that the connecting column 42 can rotate inside the cross slot 61. When the circular plate 45 is loosened, the slide bar 43 will be pushed by the second spring 44 to clamp the cross slot 61, so that the connecting column 42 cannot rotate. When the connecting column 42 rotates, it will drive the second central axis 5 to rotate, and the rotation of the second central axis 5 will drive the winding wheel 51 thereon to rotate, and the rotation of the winding wheel 51 will reel in the wire rope 52, so that the second clamping plate 32 is pulled into the inside of the retreat groove 31, so that the first central axis 3 can rotate in any direction inside the distribution roller 2. Under the friction between the distribution roller 2 itself and the inner wall of the storage shell 1 and the push between the first clamping plate 24 and the first clamping block 22, the distribution roller 2 itself will not rotate, thereby preventing the leakage of rice seeds during movement.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
