A high-efficiency production equipment for microbial controlled-release fertilizer

Abstract

This utility model relates to the field of microbial controlled-release fertilizer processing and discloses a high-efficiency microbial controlled-release fertilizer production equipment, including a shell. Two sets of bearings are embedded inside the shell. A crushing roller is fixedly connected to the inner ring of each set of bearings. Gears are fixedly connected to one end of each crushing roller near the bearing. A first motor is fixedly connected to the front of the shell. This device drives the crushing rollers to rotate via the first motor, causing the two gears to mesh and rotate, thus crushing the raw materials. A second motor drives an eccentric wheel to rotate. During rotation, the eccentric wheel intermittently contacts a wear-resistant block. The wear-resistant block, under pressure, pushes a slider and a limiting plate to slide within a chute and a groove, respectively. When the limiting plate descends, it compresses a spring. Based on the spring's characteristics, when no force is applied, it pushes the limiting plate and resets the screening frame and screen, causing them to reciprocate under the action of the eccentric wheel and spring. This allows for rapid crushing and screening of the raw materials.

Description

Technical Field

[0001] This utility model relates to the field of microbial controlled-release fertilizer processing, specifically a high-efficiency production equipment for microbial controlled-release fertilizer. Background Technology

[0002] Microbial controlled-release fertilizer is a novel type of fertilizer that integrates microbial technology and controlled-release fertilizer processing. It possesses both the ecological adaptability and growth-promoting functions of microbial fertilizers, and achieves precise nutrient release through controlled-release technology. It combines high efficiency and environmental friendliness in agricultural production. Microbial controlled-release fertilizer is made from live microorganisms (such as rhizobia, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, etc.) as its core, combined with controlled-release materials (such as polymers, natural polysaccharides, etc.) through a special process. Its core lies in encapsulating microorganisms or nutrients through a controlled-release carrier, allowing the microorganisms to colonize and reproduce under suitable conditions, while simultaneously achieving the slow release of nutrients, thus achieving the dual effects of "microbial growth promotion" and "precise nutrient supply."

[0003] When producing microbial controlled-release fertilizer, the material is usually pre-processed by crushing to ensure uniformity of subsequent mixing. At the same time, in order to ensure the consistency of material size, the crushed material needs to be manually transferred to screening equipment. This method is not only inefficient but also increases the workload of the staff. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency production equipment for microbial controlled-release fertilizer, so as to solve the problem that during the crushing process, the crushed material needs to be transferred to the screening container manually, which reduces production efficiency and increases workload.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency microbial controlled-release fertilizer production device, comprising a shell, two sets of bearings embedded inside the shell, a crushing roller fixedly connected to the inner ring of each set of bearings, and gears fixedly connected to one end of each crushing roller near the bearing. A first motor is fixedly connected to the front of the shell. A groove is formed inside the shell, and a limiting plate is slidably connected to the inner wall of the groove. A screening frame is fixedly connected inside the limiting plate, and a screening mesh is installed inside the screening frame by screws. Six springs are fixedly connected inside the groove. Two sliding grooves are formed on the outer surface of the shell, and a slider is slidably connected to the inner wall of each sliding groove. A second motor is fixedly connected to the left and right sides of the shell, and an eccentric wheel is fixedly connected to the output end of each second motor.

[0006] Preferably, a guide block is fixedly connected to the upper surface of the screening frame, and the two gears mesh with each other.

[0007] Preferably, one end of the crushing roller near the bearing passes through the bearing and extends to the outside of the housing, and the other end of the crushing roller near the bearing is fixedly connected to the output end of the first motor.

[0008] Preferably, the sides of the two sliders that are close to each other are fixedly connected to the outer surface of the screening frame, and the end of each spring that is away from the slot is fixedly connected to the bottom surface of the limiting plate.

[0009] Preferably, one end of the two crushing rollers near the bearing passes through the bearing and extends to the outside of the housing.

[0010] Preferably, the upper surface of the outer shell is fixedly connected to a feed hood.

[0011] Preferably, a wear-resistant block is fixedly connected to the upper surface of each slider, and the wear-resistant block is located below the eccentric wheel.

[0012] Preferably, the outer surface of the guide block is slidably connected to the interior of the outer shell, and the guide block adopts a ramp design.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a first motor to drive the crushing rollers to rotate, causing two gears to mesh and rotate. This allows the two gears to drive the two crushing rollers to rotate and effectively crush the raw materials. A second motor drives an eccentric wheel to rotate. During rotation, the eccentric wheel intermittently contacts the wear-resistant block. When the wear-resistant block is under force, it pushes the slider and the limiting plate to slide up and down on the inner walls of the chute and the groove, respectively. The limiting plate descends to compress the spring, and according to the characteristics of the spring, when the force is no longer applied, it pushes the limiting plate and drives the screening frame and the screening screen to reset. This causes the eccentric wheel and the spring to reciprocate, enabling the raw materials to be crushed and quickly screened. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-5 As shown, a high-efficiency microbial controlled-release fertilizer production device includes a shell 1, inside which two sets of bearings 3 are embedded. Each set of bearings 3 has a crushing roller 4 fixedly connected to its inner ring. Gears 5 are fixedly connected to one end of each crushing roller 4 near the bearing 3. A first motor 6 is fixedly connected to the front of the shell 1. A groove 7 is opened inside the shell 1. A limit plate 8 is slidably connected to the inner wall of the groove 7. A screening frame 9 is fixedly connected inside the limit plate 8. A screening mesh 11 is installed inside the screening frame 9 by screws. Six springs 12 are fixedly connected inside the groove 7. Two sliding grooves 13 are opened on the outer surface of the shell 1. A slider 14 is slidably connected to the inner wall of each sliding groove 13. A second motor 16 is fixedly connected to the left and right sides of the shell 1. An eccentric wheel 17 is fixedly connected to the output end of each second motor 16.

[0018] Through the above scheme, the second motor 16 drives the eccentric wheel 17 to rotate, causing it to intermittently contact the wear-resistant block 15, thereby indirectly pushing the slider 14 and the limiting plate 8 to slide on the inner walls of the slide groove 13 and the groove 7 respectively. At the same time, when the limiting plate 8 slides, it can drive the screening frame 9 to move and pressurize the spring 12. Through the designed spring 12, according to the characteristics of the spring 12, it can push the screening frame 9 and the crushed material inside to vibrate and screen when no force is applied.

[0019] A guide block 10 is fixedly connected to the upper surface of the screening frame 9. Two gears 5 mesh with each other. One end of the crushing roller 4 near the bearing 3 passes through the bearing 3 and extends to the outside of the outer shell 1. The other end of the crushing roller 4 near the bearing 3 is fixedly connected to the output end of the first motor 6. With the guide block 10, the guide block 10 can effectively prevent the falling material from falling into the groove 7 through the gap between the screening frame 9 and the outer shell 1. With the two gears 5 meshing, the stability of the two crushing rollers 4 during rotation can be ensured.

[0020] The two sliders 14 are fixedly connected to the outer surface of the screening frame 9 on their sides. The end of each spring 12 away from the groove 7 is fixedly connected to the bottom surface of the limiting plate 8. The ends of the two crushing rollers 4 near the bearing 3 pass through the bearing 3 and extend to the outside of the outer shell 1. Through the spring 12, the limiting plate 8 can be pushed to reset multiple times according to the characteristics of the spring 12, thereby indirectly pushing the screening frame 9 to move.

[0021] The upper surface of the outer shell 1 is fixedly connected to the feed hood 2. Each slider 14 has a wear-resistant block 15 fixedly connected to its upper surface. The wear-resistant block 15 is located below the eccentric wheel 17. The outer surface of the guide block 10 is slidably connected to the inside of the outer shell 1. The guide block 10 adopts a ramp design. With the feed hood 2, the material can be prevented from jumping out when the two crushing rollers 4 are rotating and crushing the material.

[0022] Working principle: The material is poured into the inside of the feed hood 2, and then the first motor 6 is started. The first motor 6 will drive one of the crushing rollers 4 to rotate. When one of the crushing rollers 4 rotates, it will drive the gear 5 and mesh with the other gear 5 to rotate, so that the two crushing rollers 4 can rotate and crush the material. The crushed material will fall into the inside of the screening frame 9 and contact the screening screen 11. Then the second motor 16 is started, and the second motor 16 will drive the eccentric wheel 17 to rotate. The eccentric wheel 17 will intermittently contact the wear-resistant block 15. When it contacts the wear-resistant block 15, it will be forceful and push the slider 14 to slide downward on the inner wall of the trough 13. When the slider 14 slides, it will drive the limiting plate 8 to slide on the inner wall of the groove 7, while compressing the spring 12 and driving the screening frame 9 and the material inside to descend. When the eccentric wheel 17 is not in contact with the wear-resistant block 15, the spring 12 will not be forceful and will push the limiting plate 8 to reset, so that the screening frame 9 can carry the material in reciprocating motion, thereby completing the crushing and screening of the material.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
