Description

Technical Field

[0001] This invention belongs to the field of rice cultivation technology, specifically a fertilization device for cultivating high-quality, high-tasting rice. Background Technology

[0002] The fertilization device for high-quality, high-tasting rice cultivation is an agricultural device that can accurately and uniformly apply fertilizer according to the fertilizer requirements of rice at different growth stages and the soil fertility. It usually integrates fertilizer storage, proportioning, transportation and spreading functions, and some also have the characteristics of fertigation and variable fertilization. It can reduce fertilizer waste, avoid soil pollution, ensure a balanced supply of nutrients to rice, and thus improve the taste quality and yield of rice.

[0003] A search revealed a rice side-deep fertilizer applicator, as disclosed in publication number CN221996032U. The applicator assembly is connected to a fertilizer tank via a fertilizer pipe and fixed below the frame for quantitative fertilization. A depth adjustment device is installed below the frame and in front of the applicator assembly to adjust the furrowing depth of the furrow opener. The furrow opener is mounted on the depth adjustment device. This invention's depth adjustment device can adjust the furrowing depth of the furrow opener simply by rotating the handle, making operation simple. Precise adjustment can be achieved using a scale, and the cost is low.

[0004] Although the above-mentioned device can adjust the depth of the furrow, in actual use, adjusting the depth of the furrow opener requires constantly turning the handle to drive the lead screw to rotate, and the rotation of the lead screw is converted into the vertical movement of the furrow opener for adjustment. This method is cumbersome, and the long-term rotation of the lead screw is time-consuming, reducing the efficiency of the preparation work before fertilization. Therefore, in order to solve the above problems, a fertilization device for high-quality and high-taste rice cultivation is proposed. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, the present invention provides a fertilization device for cultivating high-quality, high-taste rice, including a base 100, and further including: an adjustment mechanism 200, which is disposed on the top outer wall of the base 100; a fertilizer tank 500, which is installed on the top outer wall of the base 100 via a shaking mechanism 300; and a conveying pipe 700, which is disposed on the outer wall of the fertilizer tank 500, and a nozzle 800 is disposed on the outer wall of the conveying pipe 700 via a connecting mechanism 400.

[0037] The adjustment mechanism 200 includes a fixed plate 201, a movable block 203 slidably connected to the inner wall of the fixed plate 201, a grooved plate 202 fixedly connected to the outer wall of the bottom end of the movable block 203, a protrusion 208 elastically connected to the inner wall of the movable block 203 via a connecting spring 207, a handle 204 fixedly connected to the outer wall of the movable block 203, and a partition 205 slidably connected to the outer wall of the handle 204.

[0038] like Figures 2 to 4 As shown, a roller 210 is rotatably connected to the inner wall of the movable block 203, a pull rope 209 is wound around the outer wall of the roller 210, and a groove 206 is provided on the inner wall of the fixed plate 201.

[0039] The above scheme is adopted: the base 100 and the front and rear rollers 210 form the main body of the fertilizer trolley that can be remotely controlled and moved. Fertilizer can be placed in the fertilizer tank 500 and pumped out to the conveying pipe 700 by the suction pump. It is then sprayed into the paddy field from the nozzle 800. The ditching plate 202 can dig ditches in the paddy field for rice planting. The depth of the ditching plate 202 can be adjusted by the adjustment mechanism 200, which is convenient and quick. The shaking mechanism 300 can automatically move and rotate the fertilizer tank 500 up and down during the movement of the trolley, so that the fertilizer inside is in a state of constant shaking to prevent solidification and clumping. The moving block 203 can move up and down in the inner wall of the fixed plate 201, driving the bottom ditching plate 202 to move vertically at the same time. The ditching plate 202 can be moved down to the bottom of the rotating wheel 600 and extended into the paddy field to dig ditches during the movement.

[0040] like Figures 2 to 4 As shown, the fixing plate 201 is fixedly connected to the top outer wall of the base 100. One end of the connecting spring 207 is fixedly connected to the outer wall of the protrusion 208, and the other end of the connecting spring 207 is fixedly connected to the inner wall of the moving block 203. The protrusion 208 is slidably connected to the inner wall of the moving block 203, and the protrusion 208 is engaged with the groove 206. One end of the pull rope 209 is fixedly connected to the outer wall of the partition 205, and the other end of the pull rope 209 is fixedly connected to the outer wall of the protrusion 208.

[0041] Using the above scheme: Under normal conditions, the connecting spring 207 on the inner wall of the movable block 203 causes the protrusion 208 to be in a pop-out state due to its elasticity, and it engages with a set of grooves 206 to fix the movable block 203 and the trenching plate 202. Multiple sets of grooves 206 are provided, which can fix the movable block 203 and the trenching plate 202 in multiple positions; one end of the handle 204 and the pull rope 209 both pass through one side of the outer wall of the fixing plate 201. The operator can hold the handle 204 and pull the partition 205 to drive one end of the pull rope 209. When the rope 209 moves, it passes through the roller 210. The rotation of the roller 210 reduces the friction between the two and changes the tension of the rope 209, so that the other end can pull the protrusion 208 into the inner wall of the moving block 203. After it disengages from the groove 206, the handle 204 can be pulled to move the moving block 203 and the ditching plate 202 vertically. The depth of the ditching plate 202 into the paddy field is adjusted to open the ditch. The adjustment operation is relatively simple and does not require a long time to rotate the threaded rod for movement, which is convenient and quick.

[0042] like Figure 5 and Figure 6As shown, the shaking mechanism 300 includes a sleeve 301, a rotating rod 305 rotatably connected to the inner wall of the sleeve 301, a cam 306 fixedly connected to the outer wall of the rotating rod 305, a synchronous pulley B304 fixedly connected to the outer wall of the rotating rod 305, a synchronous pulley A302 being driven to the outer wall of the synchronous pulley B304 via a synchronous belt 303, a stop block 309 fixedly connected to the outer wall of the bottom end of the base 100, a rotating wheel 600 rotatably connected to the outer wall of the stop block 309, an arc groove 307 being opened on the inner wall of the sleeve 301, and a round block 308 fixedly connected to the outer wall of the fertilizer bucket 500.

[0043] The above scheme is adopted: the fertilizer bucket 500 is located inside the sleeve 301, and is supported by the rotating rod 305 and cam 306 in the sleeve 301, and the round block 308 is always in contact with the inner wall of the arc groove 307; when the base 100 moves, the rotating wheel 600 rotates, and the synchronous wheel A302 fixed on its outer wall will rotate synchronously. The synchronous wheel A302 is located in the inner wall of the stop block 309, and the synchronous belt 303 passes through the stop block 309, the base 100 and the outer wall of the sleeve 301. Driven by the synchronous wheel A302, the synchronous wheel B304 can be driven to rotate through the synchronous belt 303.

[0044] like Figure 5 and Figure 6 As shown, the sleeve 301 is fixedly connected to the top outer wall of the base 100, the fertilizer bucket 500 is in contact with the inner wall of the sleeve 301, and the cam 306 is in contact with the bottom outer wall of the fertilizer bucket 500; the synchronous pulley A302 is fixedly connected to the outer wall of the rotating wheel 600, the synchronous pulley A302 is rotatably connected to the inner wall of the stop block 309, the synchronous belt 303 passes through the outer wall of the base 100, and the round block 308 is in contact with the inner wall of the arc groove 307.

[0045] The above solution works as follows: When the synchronous pulley B304 rotates, it drives the rotating rod 305 to rotate synchronously, causing the cam 306 to rotate with the rotating rod 305. The rotating rod 305 passes through the base circle end of the cam 306. When the cam 306 rotates, it makes an eccentric motion. When the protruding end rotates to contact the outer wall of the bottom end of the fertilizer barrel 500, it can push the fertilizer barrel 500 to move upward. During the movement, the round block 308 moves in the arc groove 307. The arc groove 307 is threaded and opened on the inner side wall of the sleeve barrel 301. When the fertilizer barrel 500 moves vertically, the round block 308 moves along the inner wall of the arc groove 307, which can drive the fertilizer barrel 500 to rotate back and forth continuously while moving vertically. This shakes the fertilizer inside to prevent clumping. The shaking effect can be achieved without the need for an additional motor or other drive equipment, further reducing the equipment cost.

[0046] like Figure 7 and Figure 8As shown, the connecting mechanism 400 includes a connecting block 401. The inner wall of the connecting block 401 is elastically connected to an insert block 403 via a telescopic spring 402. The outer wall of the insert block 403 is fixedly connected to a slide rod 404. The outer wall of the connecting block 401 is rotatably connected to a rotating ring 405. The outer wall of the rotating ring 405 is provided with a groove 406. The outer wall of the nozzle 800 is provided with a slot 407.

[0047] Using the above scheme: the connecting block 401 can install the nozzle 800. The nozzle 800 can be fixed in the inner wall of the connecting block 401 by the insertion block 403 engaging with the slot 407. The nozzle 800 can be connected to the connecting block 401 and the conveying pipe 700 to fertilize the paddy field after the furrowing plate 202 has opened. Under normal conditions, the extension spring 402 keeps the insertion block 403 in the popped-out state due to its elasticity. When the operator manually moves the rotating ring 405, the insertion block 403 can be moved into the inner wall of the connecting block 401 to release the restriction on the nozzle 800 and also to install the nozzle 800.

[0048] like Figure 7 and Figure 8 As shown, the connecting block 401 is fixedly connected to the outer wall of the conveying pipe 700, one end of the telescopic spring 402 is fixedly connected to the outer wall of the insert block 403, and the other end of the telescopic spring 402 is fixedly connected to the inner wall of the connecting block 401; the insert block 403 is engaged with the slot 407, the slide rod 404 is in contact with the inner wall of the inclined groove 406, and the insert block 403 is slidably connected to the inner wall of the connecting block 401.

[0049] Using the above solution: When the rotating ring 405 rotates, the inclined groove 406 will squeeze the slide rod 404. Since the slide rod 404 is fixed to the insert block 403 and both can only move laterally, it will drive the two sets of insert blocks 403 to move into the inner wall of the connecting block 401 at the same time, compressing the telescopic spring 402. After moving completely into the inner wall of the connecting block 401, the insert block 403 can disengage from the slot 407 and the nozzle 800 can be removed. Alternatively, the nozzle 800 can be inserted into the connecting block 401 so that the insert block 403 corresponds to the slot 407. When the rotating ring 405 is released, the inclined groove 406 will no longer exert pressure on the slide rod 404. The telescopic spring 402 will drive the insert block 403 to pop out and lock into the slot 407 under the action of elasticity, so that the disassembly and installation can be completed conveniently and quickly.

[0050] Working principle and usage process of this invention:

[0051] The operator can first fill the fertilizer tank 500 with fertilizer suitable for high-quality, high-taste rice through the feed inlet, then hold the handle 204 and pull the partition 205 outward. The pull rope 209 will pull the protrusion 208 to move and compress the connecting spring 207, so that the protrusion 208 is disengaged from the groove 206 on the inner wall of the fixing plate 201. Then, the operator can pull the handle 204 up and down to move the moving block 203 and the bottom ditching plate 202 vertically. After adjusting to the ditching depth suitable for rice cultivation, the operator can release the partition 205. Under the elastic force of the connecting spring 207, the protrusion 208 will reset and be locked into the corresponding groove 206, thus completing the ditching depth fixation.

[0052] Next, the control system causes the base 100 to move along a preset path in the paddy field via the front and rear rollers 210. When the rotating wheel 600 rotates, the synchronous wheel A302 rotates synchronously, which drives the synchronous wheel B304 and the rotating rod 305 to rotate via the synchronous belt 303. The rotating rod 305 drives the cam 306 to make an eccentric motion. When the protruding end of the cam 306 contacts the bottom of the fertilizer barrel 500, it pushes it to move upward. At the same time, the round block 308 on the outer wall of the fertilizer barrel 500 moves along the threaded arc groove 307 on the inner wall of the sleeve barrel 301, causing the fertilizer barrel 500 to rotate back and forth while moving vertically, continuously shaking the internal fertilizer to prevent it from solidifying and clumping.

[0053] During the movement of the equipment, the pre-fixed depth trenching plate 202 extends into the paddy field soil and opens up uniform trenches in the field as the base 100 moves, reserving space for subsequent fertilization and adapting to the planting row spacing and soil covering requirements of high-quality rice.

[0054] Simultaneously, a suction pump can be activated to extract fertilizer from fertilizer tank 500 and transport it through conveying pipe 700 to nozzle 800. Nozzle 800 then evenly sprays the fertilizer into the trenches opened by trenching plate 202, achieving simultaneous trenching and fertilization operations and improving the accuracy and efficiency of fertilization.

[0055] After the work is completed, when it is necessary to clean the inside of the nozzle 800, the rotating ring 405 of the connecting mechanism 400 can be manually rotated. The sliding rod 404 is squeezed by the inclined groove 406, which drives the insert block 403 to compress the telescopic spring 402 and disengage it from the slot 407. The nozzle 800 can then be removed for cleaning. After cleaning, the rotating ring 405 is rotated again, and the nozzle 800 is inserted into the mounting port of the connecting block 401, so that the slot 407 on the outer wall of the nozzle 800 corresponds to the position of the insert block 403 on the inner wall of the connecting block 401. The rotating ring 405 is then released, and the telescopic spring 402 pushes the insert block 403 out under the action of elasticity, which is then inserted into the slot 407. This allows for a convenient and quick fixed connection between the nozzle 800 and the conveying pipe 700.
