Description

Technical Field

[0001] This utility model relates to the technical field of bio-organic fertilizer production equipment, and in particular to a bio-organic fertilizer screening device. Background Technology

[0002] Screening is a crucial step in the production of bio-organic fertilizer. Its purpose is to classify the fermented and decomposed organic fertilizer according to different particle sizes to meet the application needs of different crops and soil conditions. High-quality screening not only improves the product quality of organic fertilizer, but also enhances its absorption and utilization rate in the soil.

[0003] However, existing bio-organic fertilizer screening devices have many problems in practical applications: Firstly, most screens are fixed installation structures, making it impossible to flexibly change screens of different mesh sizes according to actual screening needs. Since bio-organic fertilizers have diverse applications, such as requiring finer organic fertilizers for seedling cultivation, while coarser organic fertilizers may be needed for soil improvement, the fixed screen design means that a single piece of equipment can only complete the screening of a single particle size. To achieve multi-particle screening, multiple pieces of equipment of different specifications are required, which undoubtedly increases the production cost of enterprises and also occupies more production space.

[0004] Secondly, traditional screening devices are prone to screen clogging when processing bio-organic fertilizer with a certain moisture content. Because bio-organic fertilizer contains a lot of humus and other sticky components, fine particles tend to stick to the screen surface during screening, while larger clumps may get stuck in the screen holes, resulting in a significant decrease in screening efficiency. To ensure the continuity of screening, operators need to frequently stop the machine to clean the screen, which not only increases labor intensity but also seriously affects the production progress.

[0005] To address these shortcomings, we have proposed a biological organic fertilizer screening device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biological organic fertilizer screening device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a biological organic fertilizer screening device, comprising a support base, annular support frames welded to both sides of the top surface of the support base, and screening drums running through the interior of the two annular support frames, rollers installed on the inner walls of the two annular support frames, and the rollers rolling and abutting against the outer wall of the screening drum, a toothed ring welded to the outer wall of the screening drum, a reduction motor fixedly installed on the top surface of the support base, and a gear installed at the output end of the reduction motor, the gear meshing with the toothed ring, a screen hole opened on the surface of the screening drum, a support ring installed on the screen hole, and a screen mesh installed on the support ring, a threaded hole opened on the surface of the support ring, and the support ring detachably connected to the screening drum by fastening bolts.

[0008] The inner wall of the screening drum is provided with conveying blades, and the conveying blades are serpentine.

[0009] The screening drum has a feed inlet and a discharge outlet at its left and right ends, respectively.

[0010] The screening drum is inclined, and the feed inlet of the screening drum is higher than the discharge outlet.

[0011] A collection box is slidably connected to the top surface of the support base, and a push handle is fixedly installed on the surface of the collection box.

[0012] A control switch is installed on the annular support frame, and the control switch is electrically connected to the geared motor via a wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model, by setting a detachable and replaceable screen, can flexibly replace the screen with a different mesh number according to the actual screening needs. When it is necessary to screen different particle sizes of biological organic fertilizer, simply unscrew the fastening bolt, remove the old screen, replace it with a new screen with the corresponding mesh number, and then fix it with the fastening bolt. This design allows one device to meet multiple screening needs without the need to equip multiple devices, reducing the production cost of enterprises, saving production space, and improving the versatility and practicality of the equipment.

[0014] (2) This utility model adopts an inclined rolling screening drum. During screening, the screening drum rotates continuously. The material inside the drum is constantly turned and rolled as the drum rotates, and moves towards the discharge port under the push of the conveying blades. This rolling screening method makes relative movement between the material and the screen, reducing the adhesion and accumulation of material on the screen surface, effectively avoiding screen hole blockage. At the same time, the continuous turning of the material ensures that each material particle can fully contact the screen, improving screening efficiency and screening accuracy, reducing the frequency of manual screen cleaning, reducing the labor intensity of operators, and ensuring the continuity of production.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A biological organic fertilizer screening device includes a support base 1, which serves as the basic support component of the entire device. Annular support frames 9 are welded to both sides of its top surface. The two annular support frames 9 are distributed in parallel and have a screening drum 3 running through them, providing stable installation support for the screening drum 3.

[0020] Rollers 10 are installed on the inner walls of the two annular support frames 9. The rollers 10 roll against the outer wall of the screening drum 3. The rolling action of the rollers 10 can reduce the frictional resistance when the screening drum 3 rotates, ensuring its smooth rotation.

[0021] A gear ring 6 is welded to the outer wall of the screening drum 3, and the gear ring 6 moves synchronously with the screening drum 3; a geared motor 7 is fixedly installed on the top surface of the support seat 1, and a gear 8 is installed at the output end of the geared motor 7, and the gear 8 meshes with the gear ring 6. Through the transmission cooperation between the gear 8 and the gear ring 6, the power of the geared motor 7 is transmitted to the screening drum 3, driving the screening drum 3 to rotate.

[0022] The surface of the screening drum 3 is provided with screen holes 12, and a support ring 13 is installed at the screen holes 12. A screen 14 is installed on the support ring 13. The screen 14 is used to classify the particle size of the material. The surface of the support ring 13 is provided with threaded holes 15. The support ring 13 is detachably connected to the screening drum 3 by fastening bolts 16, which makes it easy to replace the screen 14 with different mesh sizes as needed.

[0023] Referring to Figure 1, the inner wall of the screening drum 3 is provided with conveying blades 11, and the conveying blades 11 are serpentine. The serpentine structure of the conveying blades 11 can extend the movement path of the material in the screening drum 3, increase the contact time between the material and the screen 14, and improve the screening effect.

[0024] Please refer to Figures 1 and 2. The left and right ends of the screening drum 3 are respectively provided with a feed inlet 4 and a discharge outlet 5. The feed inlet 4 is used to feed in the biological organic fertilizer to be screened, and the discharge outlet 5 is used to discharge the coarse particles that do not meet the particle size requirements after screening.

[0025] Please refer to Figures 1 and 2. The screening drum 3 is inclined, and the feed inlet 4 of the screening drum 3 is higher than the discharge outlet 5. With the help of the material's own gravity and the push of the conveying blades 11, the material can be moved towards the discharge outlet 5, thus preventing the material from accumulating inside the screening drum 3.

[0026] Please refer to Figures 1 and 2. A collection box 2 is slidably connected to the top surface of the support base 1. The collection box 2 is located below the screening drum 3 and is used to collect fine particles that meet the particle size requirements after screening. A push handle is fixedly installed on the surface of the collection box 2, which makes it easy to pull the collection box 2 out of the support base 1 and to conveniently pour out the material.

[0027] Please refer to Figures 1 and 2. A control switch 17 is installed on the annular support frame 9. The control switch 17 is electrically connected to the geared motor 7 through a wire. The start, stop and speed adjustment of the geared motor 7 can be controlled by the control switch 17, thereby controlling the rotation state of the screening drum 3.

[0028] Working Principle: During operation, according to the required particle size of the bio-organic fertilizer to be screened, a screen 14 with the corresponding mesh size is selected. The support ring 13 and screen 14 are fixed to the screen holes 12 of the screening drum 3 by fastening bolts 16 through threaded holes 15 on the support ring 13. The reduction motor 7 is started via control switch 17, which drives gear 8 to rotate. Gear 8 meshes with gear ring 6, driving the screening drum 3 to rotate under the support of rollers 10 on the annular support frame 9. The bio-organic fertilizer to be screened is fed into the screening drum 3 through the feed inlet 4. Under the rotation of the screening drum 3 and the pushing action of the serpentine conveyor blades 11, the material tumbles and rolls with the drum and moves towards the discharge outlet 5. During this process, fine particles that meet the particle size requirements fall through the screen 14 and screen holes 12 into the collection box 2 below, while coarse particles that do not meet the requirements are discharged from the discharge outlet 5. After screening is completed, control switch 17 is turned off to stop the reduction motor 7. To stop working, pull the collection box 2 off the support base 1 using the push handle and pour out the collected fine particulate material.

[0029] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
