Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer manufacturing technology, specifically relating to a manure sieving device for preparing organic fertilizer from cow manure. Background Technology

[0002] Cow manure, as an important agricultural waste, is rich in organic matter and various nutrients, such as nitrogen, phosphorus, and potassium, which are essential for plant growth. The cellulose and hemicellulose in cow manure are important raw materials for making organic fertilizer. Its fine texture and ease of fermentation and decomposition provide excellent conditions for its transformation into bio-organic fertilizer.

[0003] Application No. 201620010945.6 discloses an organic fertilizer impurity screening device, belonging to the field of organic fertilizer, and specifically relating to such a device. It includes a conveyor belt, a support frame, and a sieve bucket. The conveyor belt is mounted at an angle on the support frame, and the sieve bucket is fixedly connected to the top of the conveyor belt. The sieve bucket has an outer wall, and a vibration source is fixedly connected to the outer wall. The vibration source is electrically connected to a vibration switch, which is mounted on the support frame. The vibration source also includes a vibration motor and a transmission shaft. The vibration motor has a shaft hole at its connection to the outer wall, and the transmission shaft passes through the shaft hole and is fixedly connected to the vibrating screen. The bottom of the vibrating screen has a collection trough, and the connection between the collection trough and the outer wall of the sieve bucket has a collection port, which is movably connected to a collection box. This patent solves the problem of not being able to remove impurities from a mixer in advance by providing an organic fertilizer impurity screening device installed before the mixer.

[0004] While the aforementioned documents can remove impurities from raw materials, they cannot solve the problem of inconsistent cow manure specifications in organic fertilizers made from cow manure. This is mainly reflected in the significant differences in the moisture content, particle size, and nutrient composition of cow manure, which poses challenges to subsequent processing and fermentation. This inconsistency requires more refined pretreatment and adjustment during the preparation of organic fertilizers to ensure the quality and fertilizer efficiency of the final product. Therefore, a manure screening device for preparing organic fertilizers from cow manure has emerged. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides a manure sieving device for preparing organic fertilizer from cow manure, comprising:

[0028] The screening mechanism 100 includes a mounting frame 101, a dispensing box 102 that is fixedly and slidably connected to the inner wall of the mounting frame 101, and a screening assembly 103 disposed on the inner wall of the mounting frame 101.

[0029] The dust removal mechanism 200 includes a feed hopper 201, a baffle 202 fixed to the side wall of the feed hopper 201 by bolts, and a dust collection assembly 203 disposed at the bottom of the feed hopper 201.

[0030] Specifically, the screening assembly 103 includes a material distribution component 103a fixedly installed on the inner wall of the mounting frame 101, and a vibration component 103b disposed on the outer surface of the material distribution component 103a for use with the material distribution component 103a.

[0031] The material distribution component 103a includes a linkage frame 103a-1 connected to the inner cavity of the mounting frame 101 via a shaft, a screening box 103a-2 fixedly installed on the inner wall of the linkage frame 103a-1, a screen 103a-3 fixedly installed in the inner cavity of the screening box 103a-2, a four-way pipe 103a-4 communicating with the outer surface of the screening box 103a-2, and a connecting seat 104a-5 fixedly installed at the bottom of the screening box 103a-2.

[0032] Furthermore, the linkage frame 103a-1, used in conjunction with the screening box 103a-2, can limit the movement of the screening box 103a-2, ensuring the stability of the screening box 103a-2 during screening and guaranteeing the efficiency of cow dung screening.

[0033] The vibration component 103b includes a drive motor 103b-1 fixedly mounted on the inner wall of the mounting bracket 101, two grooved pulleys 103b-2 fixedly mounted on the output end of the drive motor 103b-1, and a transmission wheel 103b-3 connected to the inner wall of the two grooved pulleys 103b-2 by a belt. The vibration component 103b also includes a transmission rod 103b-4 fixedly mounted on the side wall of the transmission wheel 103b-3, and an eccentric 103b-5 fixedly mounted on the end of the transmission rod 103b-4. The eccentric 103b-5 is connected to the outer surface of the connecting seat 104a-5 by a bearing.

[0034] Preferably, the transmission rod 103b-4 is positioned away from the center of the eccentric 103b-5. When the transmission shaft 203d rotates, it drives the eccentric 103b-5 to perform circular motion around the transmission rod 103b-4 as the axis. In conjunction with the connecting seat 104a-5, it drives the screening box to perform rapid and high-frequency reciprocating motion, creating a vibration effect.

[0035] The vacuuming assembly 203 includes a vacuum box 203a fixedly installed at the bottom of the feed hopper 201, a vacuum pipe 203b connected to the bottom of the vacuum box 203a, and a transfer box 203c connected to the end of the vacuum pipe 203b. The vacuuming assembly 203 also includes a drive shaft 203d adapted to be installed on the outer surface of the transfer box 203c, a blade 203e fixedly installed on the outer surface of the drive shaft 203d, and a dust outlet pipe 203f connected to the outer surface of the transfer box 203c.

[0036] It should be noted that the two grooved wheels 103b-2 are linked to the drive shaft 203d via a belt. The rotation of the drive shaft 203d drives the blades 203e to rotate, generating suction in the transfer box 203c. This suction, combined with the suction pipe 203b and the suction box 203a, removes the dust generated during vibration and discharges it through the dust removal port.

[0037] In use, cow dung is placed in the feed hopper 201, and the baffle 202 is pushed upward and fixed with bolts. The cow dung enters the screening box 103a-2 through the feed hopper 201. The drive motor 103b-1 runs, driving the two grooved wheels 103b-2 to rotate. The two grooved wheels 103b-2 drive the transmission wheel 103b-3 via a belt. The rotation of the transmission wheel 103b-3 drives the eccentric eccentric 103b-5 to rotate around the transmission rod 103b-4. This works in conjunction with the connecting seat 104a-5 to drive the screening box to move quickly and at high frequency. The reciprocating motion creates a vibration effect, which filters the cow manure into three different sizes through the screen 103a-3. The manure then falls into the dispensing box 102 through the four-way pipe 103a-4. The linkage frame 103a-1 ensures the stability of the screening box during vibration. At the same time, the two grooved wheels 103b-2 drive the drive shaft 203d to rotate through the belt. The rotation of the drive shaft 203d drives the blades 203e to rotate, generating suction in the transfer box 203c. This suction, combined with the dust suction pipe 203b and the dust suction box 203a, removes the dust generated during vibration and discharges it through the dust removal port.

[0038] In summary, this method not only ensures that cow manure is evenly and efficiently separated into three specifications during the screening process, improving product uniformity and market competitiveness, but also reduces dust pollution during operation through stable vibration screening and an effective dust collection system, improving the operating environment, enhancing the overall performance and efficiency of the equipment, and realizing the resource utilization of cow manure while ensuring the continuity and safety of operation.
