Description

Technical Field

[0001] The present invention relates to the technical field of seed cultivation devices, and particularly to a rice seed cultivation device and a method for using the same. Background Art

[0002] Rice is a kind of herbaceous rice genus and also the most important and oldest one as food in the rice genus. It is native to China and was planted in the Yangtze River Basin of China 7,000 years ago. According to the type of paddy rice, rice can be divided into indica rice and japonica rice, early rice and middle-late rice, glutinous rice and non-glutinous rice. Generally, rice is cultivated in paddy fields, and the soilless cultivation is floating rice. In the research and development process of rice seeds, it is necessary to cultivate and hybridize the seeds to obtain high-yield rice varieties. At this time, a seed cultivation device is required. One of the steps is to germinate the rice. Germination is an important measure to ensure that after the seeds absorb sufficient water, the nutrients in the seeds are rapidly decomposed and transported to supply the growth of the young embryo. Rice seed germination is an important means to improve the seed germination rate and promote uniform germination. The currently commonly used rice seed cultivation devices can well promote the growth and development of seeds, but when it is necessary to pull out the rice seedlings, it is more cumbersome. In order to reduce the damage to the roots and stems of the seedlings, the artificial method is used for pulling out the seedlings. First, the seedlings are irrigated, then the soil is loosened, and finally the seedlings are pulled out. The whole process is time-consuming and laborious. Moreover, after the rice seeds grow, the weight of the whole cultivation device is relatively large, and it is not convenient to move. It requires the staff to keep bending down to work, which causes great harm to the body. Therefore, we propose a rice seed cultivation device and a method for using the same. Summary of the Invention

[0003] The rice seed cultivation device and the method for using the same proposed by the present invention solve the above-mentioned deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A rice seed cultivation device includes a body, and further includes: A placement plate, inside the body, for placing the cultivated rice seed samples; An extraction mechanism, inside the body, for extracting the placement plate; A lifting mechanism, inside the body, for lifting and adjusting the placement plate; A soil loosening mechanism, inside the body, for loosening the soil for rice seed cultivation; A driving mechanism, on the top of the body, for power output to the lifting mechanism and the soil loosening mechanism, and one end of the driving mechanism is respectively connected to the lifting mechanism and the soil loosening mechanism.

[0005] Further, the lifting mechanism includes a bidirectional threaded rod rotatably connected to the interior of the machine body. Both ends of the bidirectional threaded rod are respectively threadedly connected with a first moving frame. Above the interior of the machine body, a first guiding rod is fixedly connected. On the two first moving frames, a first threaded hole and a first guiding hole are respectively formed.

Inside the two sides of the sleeve corresponding to the trapezoidal clamping block, movable cavities are respectively formed. The trapezoidal clamping block is movably sleeved inside the movable cavity. On one side of the trapezoidal clamping block, a return spring is fixedly connected. The return spring is movably sleeved inside the movable cavity.

[0008] Further, the extraction mechanism further includes extraction rods symmetrically and fixedly connected to the top of the placement plate. At the top of the two extraction rods, first trapezoidal traction blocks are respectively fixedly connected. Below the two extraction rods, a second trapezoidal traction block is movably sleeved. The two first trapezoidal traction blocks and the second trapezoidal traction block respectively pass through the interior of the sleeve movably. The trapezoidal clamping block is respectively clamped with the first trapezoidal traction block and the second trapezoidal traction block.

[0009] Further, the soil loosening mechanism includes a reciprocating lead screw fixedly connected to the interior of the machine body. A second moving frame is threadedly connected to the reciprocating lead screw. A second linkage rod is rotatably connected to the second moving frame. At the top end of the second linkage rod, a gear disk is fixedly connected. Below the second linkage rod, a plurality of scraping plates are fixedly connected in an array. Below the interior of the machine body corresponding to the reciprocating lead screw, a second guiding rod is fixedly connected. On the second moving frame, a second threaded hole and a second guiding hole are respectively formed. The reciprocating lead screw is threadedly sleeved inside the second threaded hole, and the second guiding rod is movably sleeved inside the second guiding hole. Inside the machine body corresponding to the gear disk, a rack is fixedly connected. One side of the gear disk is in meshing transmission with the rack.

[0010] Further, a fixed frame is fixedly connected to the lower part inside the machine body. A placement opening is formed in the fixed frame. The placement plate is movably sleeved inside the placement opening. Clamping assemblies are symmetrically arranged on the top of the fixed frame. The clamping assemblies include push rod motors symmetrically and fixedly connected to the top of the fixed frame. The output end of the push rod motor is fixedly connected to a traction plate. Two ends of one side of the traction plate are respectively fixedly connected with L-shaped clamping plates. The clamping plates are in contact with the placement plate. Two trapezoidal sliders are symmetrically and fixedly connected to the bottom of the traction plate. Trapezoidal chutes are respectively formed in the top of the fixed frame corresponding to the trapezoidal sliders. The trapezoidal sliders are movably sleeved inside the trapezoidal chutes. Further, the driving mechanism includes a motor frame fixedly connected to the top of the machine body. A driving motor is fixedly connected to the motor frame. The output shaft of the driving motor is fixedly connected to a first pulley. A second pulley is fixedly connected to one end of the bidirectional threaded rod corresponding to the first pulley. A third pulley is fixedly connected to one end of the reciprocating screw rod corresponding to the second pulley. The same belt is connected in transmission between the outside of the third pulley and the second pulley and the first pulley.

[0011] Further, a plurality of placement holes are formed in the placement plate in an array. Seed cultivation cans are respectively movably sleeved inside the plurality of placement holes. A plurality of water seepage holes are formed in the seed cultivation cans in an array.

[0012] A usage method of a rice seed cultivation device, which is applicable to the rice seed cultivation device described in any one of the above, is as follows: Place the rice seeds to be cultivated inside the seed cultivation cans, and then place the seed cultivation cans inside the placement holes. When seedling pulling is required, the operator starts the driving motor. When the driving motor starts, it drives the synchronous rotation of the first pulley, and at the same time drives the rotation of the second pulley and the third pulley through the belt. The rotation of the second pulley drives the rotation of the bidirectional threaded rod. The rotation of the bidirectional threaded rod drives the movement of the first moving frame. The movement of the first moving frame drives the swing of the traction arm. Through the swing of the traction arm, the height position of the linkage plate is adjusted. The rotation of the third pulley drives the synchronous rotation of the reciprocating screw rod. The rotation of the reciprocating screw rod drives the reciprocating movement of the second moving frame. Through the reciprocating movement of the second moving frame, the second linkage rod is synchronously driven to move. When the reciprocating movement of the second linkage rod drives the gear disk to move, through the meshing transmission between the movement of the gear disk and the rack, through the rotation of the gear disk, the second linkage rod is driven to rotate. The rotation of the second linkage rod drives the synchronous rotation of the scraper, so as to loosen the soil. When the linkage plate moves downward, the sleeve moves downward synchronously. At the same time, the first trapezoidal traction block and the extraction rod enter the interior of the sleeve. At the same time, the first trapezoidal traction block squeezes the trapezoidal block, so that the first trapezoidal traction block smoothly enters the interior of the sleeve and contacts the bottom of the first trapezoidal traction block. At the same time, the trapezoidal block is reset by the return spring, so as to latch the first trapezoidal traction block; After the first trapezoidal traction block is latched with the trapezoidal block, the drive motor stops working. At this time, the water inlet pipe injects irrigation water into the interior of the spray panel, and the irrigation water is sprayed onto the seed cultivation tank through the nozzle, so as to spray the cultivated rice seeds; After the spraying is completed, the drive motor starts in the reverse direction, and at the same time, the first pulley rotates in the reverse direction. At the same time, the belt drives the second pulley and the third pulley to change direction. The reverse rotation of the second pulley drives the bidirectional threaded rod to rotate in the reverse direction. The reverse rotation of the bidirectional threaded rod drives the first moving frame to reset. At the same time, the linkage plate is driven to move upward through the traction arm, and at the same time, the sleeve is driven to move. The movement of the sleeve drives the extraction rod to move upward synchronously, and at the same time, the placement plate is driven to move upward, so as to drive the seed cultivation tank to move upward and away from the bottom of the machine body; When it is necessary to place the placement plate back into the fixed frame, the drive motor starts in the forward direction again, so as to drive the linkage plate to move downward, so as to drive the sleeve to move downward, and drive the extraction rod and the placement plate to move downward and enter the interior of the fixed frame. At this time, the start of the push rod motor drives the traction plate to move along the trapezoidal chute through the trapezoidal slider, so as to drive the movement of the block and clamp and fix the placement plate; When the sleeve continues to move downward, the trapezoidal block continues to move downward, so as to move to the bottom of the second trapezoidal traction block. At this time, the drive motor starts in the reverse direction, drives the sleeve to move upward again, and at the same time, the trapezoidal block is pushed in the opposite direction by the return spring, so as to drive the second trapezoidal traction block to move upward synchronously. When the second trapezoidal traction block moves upward and abuts against the first trapezoidal traction block, since the placement plate is fixed and cannot move, therefore, when the sleeve continues to move upward, through the trapezoidal part at the bottom of the second trapezoidal traction block, the trapezoidal block moves upward and separates from the second trapezoidal traction block and the first trapezoidal traction block, so that the sleeve is separated from the extraction rod.

[0013] Compared with the existing technology, the beneficial effects of the present invention are: 1. By installing an extraction mechanism, a lifting mechanism and a soil loosening mechanism, the present invention performs rapid seedling pulling and soil loosening treatments on the cultivation of rice seeds. The extraction mechanism extracts the placement plate by latching the trapezoidal block with the first trapezoidal traction block, and the trapezoidal block is separated from the first trapezoidal traction block by abutting the trapezoidal block against the second trapezoidal traction block, so as to release the extraction of the placement plate; 2. The present invention drives the power output of the device mechanism by installing a driving mechanism, a clamping assembly, and a spraying mechanism. Among them, the driving mechanism is started by a driving motor to drive the first pulley to rotate synchronously, and the rotation of the first pulley drives the synchronous rotation of the second pulley and the third pulley respectively through a belt; In summary, the device can not only quickly loosen the soil, pull out seedlings, and spray the rice seed samples during cultivation, but also complete the operations from seed placement, soil loosening, seedling spraying to seedling pulling through mechanical structures and motor drives, reducing the manual labor intensity, especially reducing the frequency of staff bending operations, improving the operation comfort. The soil loosening mechanism can achieve a composite movement of "reciprocating translation + rotational soil loosening", which can not only break the soil hardening but also reduce the pulling damage to the seedling roots caused by traditional rigid soil loosening.

Embodiment 2

[0022] A method for using a rice seed cultivation device, which is applicable to the above-mentioned rice seed cultivation device, and the steps are as follows: Place the rice seeds to be cultivated inside the seed cultivation can 10, and then place the seed cultivation can 10 inside the placement hole 9. When seedling pulling is required, the operator starts the driving motor 1101. When the driving motor 1101 starts, it drives the synchronous rotation of the first belt pulley 1102, and at the same time drives the rotation of the second belt pulley 1103 and the third belt pulley 1104 through the belt 1105. The rotation of the second pulley 1103 drives the rotation of the bidirectional threaded rod 201. The rotation of the bidirectional threaded rod 201 drives the first moving frame 202 to move. The movement of the first moving frame 202 drives the traction arm 203 to swing. Through the swing of the traction arm 203, the linkage plate 205 is driven to adjust its height position; The rotation of the third pulley 1104 drives the reciprocating screw rod 501 to rotate synchronously. The rotation of the reciprocating screw rod 501 drives the second moving frame 503 to move reciprocally. Through the reciprocating movement of the second moving frame 503, the second linkage rod 504 is driven to move synchronously. When the reciprocating movement of the second linkage rod 504 drives the gear disk 506 to move, through the meshing transmission between the movement of the gear disk 506 and the rack 507, the rotation of the gear disk 506 drives the second linkage rod 504 to rotate. The rotation of the second linkage rod 504 drives the scraper 505 to rotate synchronously, so as to loosen the soil; When the linkage plate 205 moves downward, the sleeve 401 is driven to move downward synchronously. At the same time, the first trapezoidal traction block 407 and the extraction rod 406 enter the interior of the sleeve 401. At the same time, the first trapezoidal traction block 407 presses the trapezoidal block 405, so that the first trapezoidal traction block 407 smoothly enters the interior of the sleeve 401 and contacts the bottom of the first trapezoidal traction block 407. At the same time, the trapezoidal block 405 is reset by the return spring 409, so as to clamp the first trapezoidal traction block 407; After the first trapezoidal traction block 407 is clamped with the trapezoidal block 405, the drive motor 1101 stops working. At this time, the water inlet pipe 304 injects irrigation water into the interior of the spray panel 302, and the irrigation water is sprayed onto the seed cultivation tank 10 through the nozzles 303, so as to spray the cultivated rice seeds; After the spraying is completed, the drive motor 1101 starts in reverse. At the same time, the first pulley 1102 rotates in reverse. At the same time, the second pulley 1103 and the third pulley 1104 are driven by the belt 1105 to change their directions. The reverse rotation of the second pulley 1103 drives the bidirectional threaded rod 201 to rotate in reverse. Through the reverse rotation of the bidirectional threaded rod 201, the first moving frame 202 is driven to reset. At the same time, the linkage plate 205 is driven to move upward through the traction arm 203, and at the same time, the sleeve 401 is driven to move. The movement of the sleeve 401 drives the extraction rod 406 to move upward synchronously, and at the same time, the placement plate 8 is driven to move upward, so as to drive the seed cultivation tank 10 to move upward and away from the bottom of the machine body 1; When it is necessary to put the placement plate 8 back into the fixed frame 7, the driving motor 1101 starts forward again, thereby driving the linkage plate 205 to move downward, thereby driving the sleeve 401 to move downward, and driving the extraction rod 406 and the placement plate 8 to move downward, and entering the inside of the fixed frame 7. At this time, the start of the push rod motor 601 drives the traction plate 602 to move along the trapezoidal chute 605 through the trapezoidal slider 604, thereby driving the movement of the L-shaped clamping plate 603 and clamping and fixing the placement plate 8; When the sleeve 401 continues to move downward, the trapezoidal block 405 continues to move downward, and thus moves to the bottom of the second trapezoidal traction block 408. At this time, the driving motor 1101 starts in the reverse direction, driving the sleeve 401 to move upward again, and at the same time pushing the trapezoidal block 405 in the opposite direction through the return spring 409, thereby driving the second trapezoidal traction block 408 to move upward synchronously. When the second trapezoidal traction block 408 moves upward and abuts against the first trapezoidal traction block 407, since the placement plate 8 is fixed and cannot move, therefore, when the sleeve 401 continues to move upward, through the trapezoidal part at the bottom of the second trapezoidal traction block 408, the trapezoidal block 405 moves upward and separates from the second trapezoidal traction block 408 and the first trapezoidal traction block 407, thereby separating the sleeve 401 from the extraction rod 406.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
