Description

Technical Field

[0001] This utility model relates to the field of rice cultivation technology, specifically a fertilization device applied to rice cultivation. Background Technology

[0002] For rice farmers, fertilization is a significant production cost. Proper fertilization can reduce fertilizer costs and improve economic efficiency while ensuring yield and quality. Scientific fertilization management can promote robust rice growth, enhance resistance to pests and diseases, reduce losses caused by pests and diseases, and further improve planting efficiency.

[0003] Existing technologies have introduced automatic fertilizer application devices to replace traditional manual, box-type fertilizer application. Generally, to prevent large pieces of fertilizer from clogging the output end of the fertilizer application device, the fertilizer needs to be stirred and crushed before use. For example, in application number CN202420111726.1, a rice fertilizer application device uses a crushing component to crush fertilizer through a stirring rod and a scraper. However, the device has the following drawbacks: for some fertilizers with high hardness or large lumps, it may not be able to completely crush them to the required particle size. In addition, during the crushing process, fertilizer may get stuck between the stirring rod, scraper, or filter plate, affecting the crushing effect and the normal operation of the device, thus resulting in low fertilization efficiency.

[0042] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0043] Figure 1-9 This invention illustrates a fertilization device for rice cultivation, comprising: a movable base 1, wherein a fertilizer box 2 is mounted on the rear side, and a feed inlet 21 is provided at the top of the fertilizer box 2; and further comprising:

[0044] The crushing assembly 3 is connected to the output end of the motor I 31 and is installed inside the fertilizer box 2, and the crushing assembly 3 is positioned opposite the feed inlet 21;

[0045] The filter cleaning assembly 4 is disposed inside the fertilizer box 2 and is located directly below the crushing assembly 3;

[0046] The water injection and stirring assembly 5 is connected to the output end of the motor II 51 and is installed inside the fertilizer box 2. The water injection and stirring assembly 5 is located directly below the filter and cleaning assembly 4. A discharge port 22 is provided on one side of the water injection and stirring assembly 5.

[0047] The fertilizer spraying assembly 6 is connected to the output end of the motor Ⅲ 61 and is located on the front side of the movable base 1. The fertilizer spraying assembly 6 and the discharge port 22 are connected through the pipe 71 of the conveying pump 7.

[0048] Working principle:

[0049] The operator puts fertilizer into the fertilizer box 2 through the feed port 21 at the top of the fertilizer box 2, and starts the motor I 31 by the external power supply. The output of the motor I 31 drives the crushing component 3 to operate, crushing the larger pieces of fertilizer into smaller particles. The fertilizer crushed by the crushing component 3 falls to the filter cleaning component 4, so that a small number of larger particles that do not meet the particle size requirements remain above the filter cleaning component 4 and are cleaned and collected after a period of time to prevent fertilizer particles from accumulating. Fertilizer particles that meet the requirements continue to fall through the filter cleaning component 4.

[0050] At this time, after the fertilizer has fallen and accumulated to a certain height (which can be judged by the observation window 23), water in a predetermined ratio with the fertilizer is injected into the fertilizer tank 2 and enters the water injection and mixing component 5. The external power supply starts the motor II 51 to mix the fertilizer and water, so that the fertilizer is fully dissolved or dispersed in the water. The delivery pump 7 is started to send the mixed fertilizer solution out of the outlet 22 on the fertilizer tank 2. The pipeline 71 delivers the solution to the fertilizer spraying component 6. The external power supply starts the motor III 61 to drive the fertilizer spraying component 6 to operate, and sprays the fertilizer solution evenly into the paddy field to complete the fertilization operation.

[0051] Among them, ① in actual use, the movable base 1 is provided with a push handle 11 for easy pushing;

[0052] ② The motor can be selected as needed, such as a 12V 600w high-power agricultural machinery motor or a 428 sprocket motor. The specific selection can be changed according to the actual size of the farmland. Similarly, the conveying pump 7 can be a model: non-clogging rotor pump YOPO, with parameters such as conveying medium: slurry, flow rate: 0.5~1000m3 / h, etc.

[0053] ③ The feed inlet 21 is a flared opening type, and the diameter of the upper opening is larger than the diameter of the lower opening, which facilitates feeding: the larger upper opening diameter makes it easier and faster to pour fertilizer into the fertilizer box 2. Especially for some bagged or bulk fertilizers, operators can more easily pour the fertilizer from the larger opening, reducing the situation of fertilizer spillage or difficulty in pouring due to the feed inlet 21 being too small, thus improving the efficiency and convenience of feeding.

[0054] Meanwhile, the trumpet-shaped design allows fertilizer to naturally converge towards the smaller opening when poured in, reducing the possibility of fertilizer accumulating or clogging at the inlet 21.

[0055] ④ The structure of the water injection and mixing assembly 5 includes: a water storage tank 52, which is installed on the side of the fertilizer tank 2 and connected to the inside of the fertilizer tank 2 via a hose; a mixing paddle 53, which is rotatably installed inside the fertilizer tank 2 and located directly below the filter and cleaning assembly 4, the rotating shaft of the mixing paddle 53 being connected to the output end of the motor II 51; and an observation window 23, which is installed on the outer wall of the fertilizer tank 2 relative to the mixing paddle 53. Working principle:

[0056] When the operator needs to add water to the fertilizer tank 2 to prepare fertilizer solution, he / she opens the valve connecting the water storage tank 52 and the fertilizer tank 2 according to the actual needs. Under the action of its own gravity (the water outlet of the water storage tank 52 is located at the upper end of the water injection and stirring assembly 5), the water flows into the fertilizer tank 2 through the hose. The motor II 51 is started by the external power supply, and its output end drives the rotating shaft of the stirring paddle 53 to rotate, thereby making the stirring paddle 53 rotate in the fertilizer tank 2 to fully stir the fertilizer particles and the injected water.

[0057] At this time, the operator can observe the situation inside the fertilizer tank 2 through the observation window 23, such as observing the degree of mixing of fertilizer and water to determine whether the expected uniformity has been achieved; observing the water level to determine whether the amount of water injected is appropriate, etc., to ensure the smooth progress of the water injection and mixing process and to prepare a fertilizer solution that meets the requirements.

[0058] This fertilization device, through the coordinated operation of the crushing component 3, the filtering and cleaning component 4, the water injection and mixing component 5, and the fertilizer spraying component 6, achieves a series of operations such as crushing, filtering, mixing, and uniform spraying of fertilizer, which meets the requirements for fertilizer processing and application in rice cultivation, and improves the utilization rate of fertilizer and the growth quality of rice.

[0059] As described above, the structure of the crushing component 3 includes:

[0060] The crushing gear set I32 is rotatably installed inside the fertilizer box 2 via a rotating shaft, and multiple sets are horizontally distributed in a linear matrix. There is a predetermined gap between each gear in the crushing gear set I32.

[0061] The crushing gear set II 320 is rotatably installed in the fertilizer box 2 via a rotating shaft, and multiple sets are horizontally distributed in a linear matrix. There is a predetermined gap between each gear in the crushing gear set II 320. The crushing gear set I 32 and the crushing gear set II 320 are in a cross-meshing state, and the meshing area is not completely close and there is a certain predetermined gap.

[0062] Gear set 33 is installed on the outside of the fertilizer box 2, and gear I 331 and gear II 332 in gear set 33 mesh with each other. One side of the drive shaft of gear I 331 is connected to the rotating shaft of crushing gear set II 320, and the other side is connected to the output end of motor I 31. The drive shaft of gear II 332 is connected to the rotating shaft of crushing gear set I 32.

[0063] Working principle:

[0064] Motor I31 is started by an external power supply. The output end of motor I31 begins to rotate. The rotation of the output end of motor I31 is connected to the transmission shaft of gear set 33, which transmits power to gear set 33. Gear set 33 transmits the power to the rotating shaft of crushing and mixing group 32 connected to it. Gear I331 drives the rotating shaft of crushing gear set II320 to rotate (the rotating shaft is rotatably installed in fertilizer box 2 by bearings. Crushing gear set I32 and crushing gear set II320 are fixedly installed on the corresponding rotating shaft, thereby realizing the rotation of the rotating shaft to drive the rotation of crushing gear set I32 and crushing gear set II). Gear I331 meshes and transmits power to gear II332, so that gear II332 drives the rotating shaft of crushing gear set I32 to rotate.

[0065] When the shaft receives power from the gear set 33, it begins to rotate. When the fertilizer enters the fertilizer box through the feed inlet, it falls into the working area of ​​the crushing gear set I 32 and the crushing gear set II 320. Since the two sets of gears mesh with each other and rotate in opposite directions, multiple crushing spaces are formed between them. When larger pieces of fertilizer enter these crushing spaces, they are subjected to the friction and extrusion forces of the gear teeth. The meshing and rotation between the gears can gradually crush and extrude the large pieces of fertilizer into smaller particles.

[0066] The gaps between multiple sets of gears arranged in a linear matrix (and the gaps between individual gears in crushing gear set I 32 and between individual gears in crushing gear set II 320) allow small fertilizer particles to fall directly. Particles that do not meet the requirements will enter the meshing area between crushing gear set I 32 and crushing gear set II 320 during the rolling of the gears for crushing. (In actual use, sharp teeth can be installed on the gears to further crush the fertilizer through mutual squeezing and shearing forces. In order to avoid jamming, the teeth of crushing gear set I 32 and crushing gear set II 320 are not completely meshed and there is a certain gap.) This more effectively breaks the fertilizer into smaller particles, which can then enter the subsequent filtration and cleaning components for further processing.

[0067] The cross-meshing gears form multiple crushing spaces. After the fertilizer enters, it will be acted upon by multiple sets of gears, which can gradually crush and squeeze large pieces of fertilizer into smaller particles. Moreover, the cross-meshing of multiple sets of gears means that even if some gears wear out or malfunction, the other gears can continue to work, maintaining a certain crushing capacity, ensuring the continuity and stability of the crushing process, reducing downtime caused by equipment failure, and improving production efficiency.

[0068] As described above, the structure of the filter cleaning component 4 includes: a filter plate 41, which is installed inside the fertilizer box 2, and there is a predetermined gap between the filter plate 41 and the crushing component 3.

[0069] The cleaning brush 42 is slidably mounted on the filter plate 41, and the cleaning brush 42 is hinged to the side of the fertilizer box 2 with an opening and closing window 43.

[0070] The recycling bin 44 is detachably connected to the outside of the fertilizer box 2 and is positioned directly below the opening window 43.

[0071] Working principle:

[0072] After being crushed by the crushing component 3, the fertilizer particles continue to fall. When they reach the filter plate 41, the pores on the filter plate 41 will screen the fertilizer particles. Smaller fertilizer particles that fit the size of the pores of the filter plate 41 will pass through the filter plate 41 and continue to fall, entering the water injection and mixing component 5 below for further processing. Larger particles will be intercepted on the upper surface of the filter plate 41 and will not be able to pass through the filter plate 41.

[0073] When a certain amount of larger particles that have been intercepted accumulate on the filter plate 41, the filter plate 41 needs to be cleaned. The cleaning brush 42 is slid on the filter plate 41 by external force. The bristles of the cleaning brush 42 will sweep up the larger particles or impurities on the surface of the filter plate 41 and move them toward the opening and closing window 43. At this time, the operator opens the hinged opening and closing window 43. The larger particles that have been gathered by the cleaning brush 42 will fall into the recycling bin 44 through the open opening and closing window 43 under the action of gravity.

[0074] Once the recycling bin 44 is full of larger particles, the operator can remove the recycling bin 44 from the fertilizer box 2 and then put it into the fertilizer box 2 through the feed inlet 21 to achieve effective utilization of fertilizer and avoid waste.

[0075] Among them, ① the cleaning brush 42 can be slidably installed on the filter plate 41 in the following ways: as in the first case, a threaded hole 91 can be provided on one side of the cleaning brush 42, and the threaded hole 91 passes through the threaded rod 92 (the threaded rod 92 is rotatably installed in the fertilizer box 2 through the bearing), and a through hole 93 is provided on the other side to directly pass through the slide rod 94. Slide rails 82 are provided on both sides inside the fertilizer box 2. The operator rotates one end of the threaded rod 92 externally (in actual use, a torque handle can be added), thereby making the threaded hole 91 on the cleaning brush 42 slide along the thread on the threaded rod 92, and the through hole 93 on the other side of the cleaning brush 42 move along the direction of the slide rod 94, so as to realize the horizontal movement of the cleaning brush 42;

[0076] The second method involves setting a spring rope 8 on the rear side of the sweeping brush 42, setting pull ropes 81 at both ends of the front side, and setting slide rails 82 on both sides inside the fertilizer box 2. The operator pulls the pull ropes 81 to make the sweeping brush 42 move outward along the slide rails 82. After the sweeping is completed, the operator releases the pull ropes 81, and the sweeping brush 42 returns to its initial position under the return force of the spring rope 8.

[0077] ② The detachable connection method of the recycling bin 44 is as follows: an n-shaped limiting block 45 is set on the side of the fertilizer bin 2, and an L-shaped fixing block 441 is set on one side of the fertilizer bin. The L-shaped fixing block 441 is fixed on the n-shaped limiting block 45.

[0078] As described above, the structure of the fertilizer spraying component 6 includes:

[0079] A semi-open mounting plate 62 is disposed on the front side of the movable base 1, and a motor Ⅲ 61 is mounted on the semi-open mounting plate 62;

[0080] Gear I 63 meshes with gear II 64 and gear III 65 on both sides through a predetermined number of tooth tips 631. Gear I 63 is composed of alternating segments of a predetermined number of tooth tips 631 and segments of toothless teeth with a predetermined arc. Gear I 63 is connected to the output end of motor III 61 through a shaft hole.

[0081] Both gear II 64 and gear III 65 are configured as half tooth tips and half toothless, and the number of tooth tips I 641 of gear II 64 and the number of tooth tips II 651 of gear III 65 match the predetermined number of tooth tips 631 of gear I 63. Both gear II 64 and gear III 65 are rotatably mounted on the semi-open mounting plate 62 via rotating column 66.

[0082] Spring I 67, one side of which is fixedly mounted on the half-open mounting plate 62, and the other side is connected to the tooth tip I 641 of gear II 64; Spring II 68, one side of which is fixedly mounted on the half-open mounting plate 62, and the other side is connected to the tooth tip II 651 of gear III 65.

[0083] The spray head assembly 69 is fixedly installed at the lower end of the rotating column 66 and is connected to the pipeline 71 of the delivery pump 7.

[0084] Working principle:

[0085] The motor Ⅲ61 on the semi-open mounting plate 62 is started by an external power supply. Its output end drives the gear Ⅰ63 connected to it through the shaft hole to start rotating. When the gear Ⅰ63 rotates, a predetermined number of its tooth tips 631 will mesh with the gears Ⅱ64 and Ⅲ65, thereby driving the gears Ⅱ64 or Ⅲ65 to rotate. Due to the alternation of the predetermined number of tooth tips 631 and the predetermined arc of the toothless tooth 632 on the gear Ⅰ63, as well as the semi-tooth tip structure of the tooth tips Ⅰ641 of the gear Ⅱ64 and Ⅱ651 of the gear Ⅲ65, the gears Ⅱ64 and Ⅲ65 exhibit a periodic rotation and stationary state.

[0086] At this time, due to the action of springs I67 and II68, when gear II64 or gear III65 rotates under the drive of gear I63, the springs will be stretched or compressed. When the toothless part 632 of the predetermined arc of gear I63 is opposite to the toothless part of gear II64 or gear III65, the elastic force of springs I67 and II68 will drive the tooth tip I641 and tooth tip II651 connected to it to rotate back, so that gear II64 or gear III65 resets.

[0087] Meanwhile, to prevent the tips of gear I 63 from getting stuck with the spring, the number of tips I 641 or tips II 651 of gear II 64 or gear III 65 is matched with a predetermined number of tips 631 of gear I 63. For example, if the number of tips of gear II 64 or gear III 65 is n and the number of slots between the tips is n-1, then the number of tips 631 of the predetermined number of tips on gear I 63 is set to n-1, which perfectly matches the number of slots n-1 between the tips of tips I 641 or tips II 651, thus achieving effective transmission.

[0088] Therefore, the periodic rotation of gears II 64 and III 65 will drive the rotating column 66 (which is mounted on the semi-open mounting plate 62 via bearings) to rotate periodically. As a result, when the pump 7 delivers the mixed fertilizer solution to the spray head assembly 69 through the pipeline 71, the spray head assembly 69 will also swing periodically along with the periodic rotation of the rotating column 66, thereby evenly spraying the fertilizer in the paddy field, expanding the spraying range, and improving the uniformity and efficiency of fertilization.

[0089] Since gears II and III rotate in the same direction, the initial positions of the relative spray head groups 69 on gears II and III are not the same, in order to ensure a more uniform spraying range. For example, the angle between the horizontal planes of the spray head groups 69 on gears II and III can be 45-60°, so as to ensure that the uniform spraying range of the spray head groups 69 does not interfere with each other.

[0090] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
