Description

Technical Field

[0001] This utility model relates to the technical field of organic fertilizer production equipment, specifically an organic fertilizer crushing device for tea planting. Background Technology

[0002] Organic fertilizers are often applied in tea tree cultivation to increase yield. The industrial production of organic fertilizers requires harmless treatment. The process includes: manure collection, dehydration, disinfection, deodorization, formula mixing, granulation, drying, sieving, packaging, and warehousing. Before formula mixing, organic fertilizers need to be crushed to improve the uniformity of mixing.

[0003] The utility model patent application with publication number "CN220900512U" discloses an organic fertilizer crushing device for tea planting, which mainly consists of a feeding module, a crushing module and a discharging module. This technology sets up a disinfection unit and a waste gas collection unit in the feeding module, so that the organic fertilizer can be disinfected during the crushing and processing feeding process, and the waste gas generated by the disinfection of the organic fertilizer can be collected through the waste gas collection unit.

[0004] The organic fertilizer crushing device for tea cultivation disclosed in the above document has the following defects: the crushing device crushes the organic fertilizer through a crushing roller group, but the organic fertilizer contains many different raw materials, which makes it difficult for some of the harder raw materials in the organic fertilizer to be crushed into small particles during the crushing process. As a result, the organic fertilizer particles after crushing are of different sizes, which affects the quality of the finished organic fertilizer.

[0005] Therefore, it can be seen that the existing organic fertilizer crushing device for tea planting does not have a structure for screening the crushed organic fertilizer. It is necessary to improve the existing shortcomings and provide a new organic fertilizer crushing device for tea planting. Utility Model Content

[0006] The purpose of this invention is to provide an organic fertilizer crushing device for tea cultivation, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an organic fertilizer crushing device for tea cultivation, comprising a frame, a reducer and a housing mounted on the upper surface of the frame, a first motor mounted on the lower surface of the frame, a first driven wheel mounted on the input end of the reducer, and a first driving wheel mounted on the output end of the first motor. The first driving wheel is connected to the first driven wheel via a first belt. Two sets of crushing rollers are rotatably connected inside the housing, and gears are mounted on the outer surfaces of both sets of crushing rollers, meshing with each other. One set of crushing rollers is mounted on the output end of the reducer. A screening assembly is provided on the lower surface of the frame, the screening assembly including a collection box, an inlet on the upper surface of the collection box, a drive assembly at one end of the collection box, four springs mounted on the inner top of the collection box, a frame mounted on the other end of every two adjacent springs, a screening plate slidably connected between the two frames, and a plurality of sieve holes on the upper surface of the screening plate.

[0009] Furthermore, the drive assembly includes a second motor, the output end of which is equipped with a second drive wheel, and a connecting shaft is rotatably connected inside the collection box. One end of the connecting shaft passes through the collection box and is equipped with a second driven wheel. The second drive wheel is connected to the second driven wheel via a second belt, and a cam is installed on the outer surface of the connecting shaft.

[0010] Furthermore, the outer surface of the collection box has two openings, one of which is rotatably connected to a baffle, and the other is slidably connected to a collection box.

[0011] Furthermore, handles are installed on the outer surfaces of both the baffle and the collection box.

[0012] Furthermore, the outer surface of the baffle is provided with a connecting rod, and the other end of the connecting rod is provided with a limiting block.

[0013] Furthermore, a limiting plate is rotatably connected to the outer surface of the frame, and the outer surface of the limiting plate abuts against the outer surface of the connecting rod.

[0014] This utility model has the following beneficial effects:

[0015] (1) By starting the second motor, the output end of the second motor drives the second driving wheel to rotate. The second driving wheel drives the second driven wheel and the connecting shaft to rotate through the second belt. During the rotation of the connecting shaft, the protruding end of the cam pushes the frame, causing the frame to move upward in the collection box. The spring gradually contracts. When the protruding end of the cam stops contacting the frame, the spring returns to its elasticity. Under the repeated impact of the cam, the screening plate vibrates inside the collection box, thereby screening the organic fertilizer particles on the screening plate. This avoids the situation where the crushed organic fertilizer particles are of different sizes, which affects the quality of the finished organic fertilizer product and achieves a better practical effect.

[0016] (2) By pushing the limiting plate outward, the limiting plate rotates outward around the hinge point with the frame, and the limiting plate and the connecting rod are no longer in contact, thereby removing the limitation of the limiting plate on the baffle. By pulling the handle on the outer surface of the baffle outward, the baffle rotates axially outward around the hinge point with the opening, thus exposing the opening. This makes it easier for workers to take out the screening plate in the collection box and remove the organic fertilizer from the upper surface of the screening plate and the screen holes, thereby increasing the practical effect of the crushing device.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is an organic fertilizer crushing device for tea cultivation, including a frame 1. A reducer 2 and a housing 3 are mounted on the upper surface of the frame 1, and a first motor 4 is mounted on the lower surface of the frame 1. A first driven wheel 5 is mounted on the input end of the reducer 2, and a first driving wheel 6 is mounted on the output end of the first motor 4. The first driving wheel 6 is connected to the first driven wheel 5 via a first belt 7. Two sets of crushing rollers 8 are rotatably connected inside the housing 3. Gears 9 are mounted on the outer surface of both sets of crushing rollers 8, and the two sets of gears 9 are meshed together. The output end of 2 is equipped with one set of crushing rollers 8. The lower surface of the frame 1 is provided with a screening component 10. The screening component 10 includes a collection box 1001. The upper surface of the collection box 1001 is provided with a feed inlet. One end of the collection box 1001 is provided with a drive component 11. Four springs 1002 are installed on the inner top of the collection box 1001. The other end of each pair of adjacent springs 1002 is provided with a frame 1003. A screening plate 1004 is slidably connected between the two frames 1003. The upper surface of the screening plate 1004 is provided with a number of screen holes.

[0027] By using the screening component 10 and the driving component 11 together, it is possible to avoid the situation where the crushed organic fertilizer has different particle sizes, which would affect the quality of the finished organic fertilizer and achieve a better practical effect.

[0028] The drive assembly 11 includes a second motor 1101, a second drive wheel 1102 is installed at the output end of the second motor 1101, a connecting shaft 1005 is rotatably connected inside the collection box 1001, one end of the connecting shaft 1005 passes through the collection box 1001 and is equipped with a second driven wheel 1103, the second drive wheel 1102 is connected to the second driven wheel 1103 through a second belt 1104, and a cam 1006 is installed on the outer surface of the connecting shaft 1005;

[0029] The outer surface of the collection box 1001 has two openings. A baffle 1007 is rotatably connected inside one of the openings, and a collection box 12 is slidably connected inside the other opening.

[0030] Both the baffle 1007 and the collection box 12 are equipped with handles 13 on their outer surfaces;

[0031] A connecting rod 1008 is provided on the outer surface of the baffle 1007, and a limiting block 1009 is provided at the other end of the connecting rod 1008.

[0032] A limiting plate 14 is rotatably connected to the outer surface of the frame 1, and the outer surface of the limiting plate 14 abuts against the outer surface of the connecting rod 1008.

[0033] In operation, the first motor 4 is started first, causing its output to drive the first drive wheel 6 to rotate. The first drive wheel 6, via the first belt 7, drives the first driven wheel 5 to rotate, causing the output of the reducer 2 to drive one set of crushing rollers 8 to rotate. Since the outer surface of the crushing roller 8 is equipped with gears 9, the rotation of the crushing roller 8 will drive the other set of crushing rollers 8 to rotate via the gears 9. Then, organic fertilizer is put into the interior of the outer casing 3, causing the two sets of crushing rollers 8 to crush the organic fertilizer. The crushed organic fertilizer falls onto the upper surface of the screening plate 1004 in the collection box 1001. The second motor 1101 is then started, causing its output to drive the second drive wheel 1102 to rotate. The second drive wheel 1102, via the second belt... 1104 drives the second driven wheel 1103 and the connecting shaft 1005 to rotate. During the rotation of the connecting shaft 1005, the protruding end of the cam 1006 pushes the frame 1003, causing the frame 1003 to move upward in the collection box 1001. The spring 1002 gradually contracts. When the protruding end of the cam 1006 stops contacting the frame 1003, the spring 1002 returns to its elasticity. Under the repeated impact of the cam 1006, the frame 1003 causes the screening plate 1004 to vibrate inside the collection box 1001, thereby screening the organic fertilizer particles on the screening plate 1004. Organic fertilizer particles smaller than the sieve holes fall into the collection box 12 for centralized collection, while organic fertilizer particles larger than the sieve holes accumulate on the upper surface of the screening plate 1004.

[0034] When a large amount of organic fertilizer accumulates on the upper surface of the screening plate 1004, the limiting plate 14 is pushed outward, causing it to rotate outward around the hinge point with the frame 1. At the same time, the limiting plate 14 and the connecting rod 1008 are no longer in contact, thus removing the limiting plate 14 from restricting the baffle 1007. By pulling the handle 13 on the outer surface of the baffle 1007 outward, the baffle 1007 is axially rotated outward around the hinge point with the opening, exposing the opening. This makes it easier for workers to remove the screening plate 1004 from the collection box 1001 and remove the organic fertilizer from the upper surface of the screening plate 1004 and the sieve holes.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
