Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer filtration technology, and in particular to an organic fertilizer grading filtration device. Background Technology

[0002] Organic fertilizer, also known as farmyard manure, is a fertilizer made from organic matter. It is characterized by its variety, wide range of sources, and long-lasting effect. The nutrients contained in organic fertilizer are mostly in an organic state, which is difficult for crops to use directly. Through the action of microorganisms, a variety of nutrients are slowly released, continuously supplying nutrients to crops. During the production process, organic fertilizers are prone to large size differences due to the varying sizes of the organic matter itself, so it is necessary to screen organic fertilizers.

[0003] Existing organic fertilizer grading and filtration devices cannot disassemble their filter screens. Organic fertilizers (such as compost and manure) usually contain organic matter with high moisture content, fibrous impurities (such as straw and weeds), or sticky substances. Once blockage occurs (such as fiber entanglement or wet material adhesion), residual material will continue to adhere to the mesh of the filter screen, resulting in a reduction in the effective screening area and a significant decrease in screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an organic fertilizer grading and filtration device to solve the problems mentioned above in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an organic fertilizer grading and filtration device, comprising a base, two elongated grooves formed on the surface of the base, and L-shaped supports slidably connected inside the two elongated grooves. Each of the vertical ends of the two L-shaped supports is provided with an installation device, the installation device comprising a first support plate and a second support plate fixedly installed on the vertical end surface of the L-shaped supports. A first mounting rail is fixedly installed on the end surface of each of the two first support plates away from the vertical end of the L-shaped supports, and a second mounting rail is fixedly installed on the end surface of each of the two second support plates away from the vertical end of the L-shaped supports. A first filter screen with a trapezoidal cross-section is slidably inserted between the two first mounting rails, and a second filter screen with a trapezoidal cross-section is slidably inserted between the two second mounting rails. The mesh size of the first filter screen is larger than that of the second filter screen.

[0006] Preferably, a baffle plate is slidably connected between each of the two first mounting rails and the two second mounting rails. A notch is formed on the top surface of each of the two first mounting rails and the two second mounting rails. A slide rod is fixedly installed on the inner wall surface of one end of the notch. A slide plate is slidably connected to the surface of the slide rod. The bottom of the slide plate is fixedly connected to the baffle plate.

[0007] Preferably, an extension plate is fixedly mounted on the side of the skateboard, and bolts are threaded onto the surface of the extension plate. Two threaded holes matching the bolts are opened on the top surfaces of the two first mounting rails and the two second mounting rails.

[0008] Preferably, the mesh size of the first filter screen is 8mm, the mesh size of the second filter screen is 3mm, and the edges of the first and second filter screens are provided with guide ridges that cooperate with the grooves of the first and second mounting rails.

[0009] The effect achieved by the above components is that the first filter screen and the second filter screen can be removed from the inside of the first mounting rail and the second mounting rail, thereby facilitating the cleaning of the first filter screen and the second filter screen, restoring the permeability of the mesh, and avoiding the impact of impurities on the subsequent filtration effect.

[0010] Preferably, a storage hopper is fixedly installed between the two L-shaped supports, a discharge pipe is fixedly installed on the bottom surface of the storage hopper, and a valve is fixedly installed on the outer wall surface of the discharge pipe.

[0013] Preferably, the surface of the base is provided with a reciprocating device to improve the screening efficiency of the first and second filter screens. The reciprocating device includes two fixed plates fixedly installed on the surface of the base. A spring is fixedly installed between the two fixed plates and the two L-shaped brackets. The spring is a compression spring with an elastic coefficient of 20 N / mm.

[0014] Preferably, the surface of the base is provided with a groove and a sliding T-shaped plate inside it, and a connecting rod is fixedly installed between the horizontal end of the T-shaped plate and the two L-shaped brackets.

[0015] Preferably, an L-shaped plate is fixedly mounted on the surface of the base, a motor is fixedly mounted on the bottom surface of the horizontal end of the L-shaped plate, and a cam is fixedly mounted on the output end of the motor through a coupling.

The mesh size of the first filter screen 205 is larger than that of the second filter screen 206. A blocking plate 207 is slidably connected between the two first mounting rails 203 and the two second mounting rails 204. A notch 208 is formed on the top surfaces of the two first mounting rails 203 and the two second mounting rails 204. A slide rod 209 is fixedly installed on the inner wall surface of one end. A slide plate 210 is slidably connected to the surface of the slide rod 209. The bottom of the slide plate 210 is fixedly connected to the baffle plate 207. An extension plate 211 is fixedly installed on the side of the slide plate 210. A bolt 212 is threadedly connected to the surface of the extension plate 211.

The mesh size of the first filter screen 205 is 8mm, and the mesh size of the second filter screen 206 is 3mm. The edges of the first filter screen 205 and the second filter screen 206 are provided with guide ridges that cooperate with the grooves of the first mounting rails 203 and the second mounting rails 204, so that the first filter screen 205 and the second filter screen 206 can be disassembled from the inside of the first mounting rails 203 and the second mounting rails 204, thereby facilitating the cleaning of the first filter screen 205 and the second filter screen 206, restoring the permeability of the mesh, and avoiding the impact of impurities on the subsequent filtration effect.

[0026] Reference Figure 1-2 As shown in this embodiment: a storage hopper 6 is fixedly installed between two L-shaped brackets 5, a discharge pipe 7 is fixedly installed on the bottom surface of the storage hopper 6, a valve 8 is fixedly installed on the outer wall surface of the discharge pipe 7, a collection groove 9 is opened on the surface of the base 1, and a collection box 10 is placed inside the collection groove 9. The storage hopper 6 is set to store fertilizer, and the valve 8 is set to control the opening and closing of the discharge pipe 7.

[0027] Reference Figure 3-4As shown in this embodiment: the surface of the base 1 is provided with a reciprocating device 3 to improve the screening efficiency of the first filter screen 205 and the second filter screen 206. The reciprocating device 3 includes two fixed plates 31 fixedly installed on the surface of the base 1. Springs 32 are fixedly installed between the two fixed plates 31 and the two L-shaped brackets 5. The elastic coefficient of the springs 32 is 20 N / mm. The compression spring has a groove 33 on the surface of the base 1 and a sliding T-shaped plate 34 inside it. A connecting rod 35 is fixedly installed between the horizontal end of the T-shaped plate 34 and the two L-shaped brackets 5. An L-shaped plate 36 is fixedly installed on the surface of the base 1. A motor 37 is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate 36. A cam 38 is fixedly installed at the output end of the motor 37 through a coupling. The cam 38 is a disc cam with an eccentricity of 15mm. The spring 32 restricts the position of the L-shaped bracket 5 inside the long groove 4. The T-shaped plate 34 and the connecting rod 35 drive the L-shaped bracket 5 to move inside the long groove 4. The motor 37 drives the cam 38 to rotate. The cam 38 drives the T-shaped plate 34 to move inside the groove 33.

[0028] Working principle: When the device is needed, first pour the fertilizer into the storage hopper 6, then open the valve 8, so that the raw material in the storage hopper 6 is evenly spread on the surface of the first filter screen 205 through the feed pipe 7. Impurities >8mm are intercepted, and particles <8mm fall through the mesh to the second filter screen 206. Then the second filter screen 206 further intercepts particles of 3-8mm. Fine fertilizer <3mm falls into the unified collection box 10, thus completing the entire fertilizer grading and filtration operation. When impurities accumulate on the surface of the first filter screen 205 to the point of affecting the filtration efficiency, such as when the accumulation thickness is >20mm, stop the equipment and clean it according to the following steps: First, loosen the bolt 212 and unscrew it from the threaded hole 213. The separation of the bolt 212 and the threaded hole 213 causes the extension plate 211 to lose its limit. With the extension plate 211 losing its limit, the slide plate 210 loses its limit on the surface of the slide rod 209. At this point, the slide plate 210 can be moved. The slide plate 210 moves on the surface of the slide rod 209, causing the baffle plate 207 to move. Continuing to slide the slide plate 210, it slides off the surface of the slide rod 209. The separation of the slide plate 210 and the slide rod 209 allows the baffle plate 207 to move out of the two first mounting rails 203. With the baffle plate 207 no longer obstructing the movement, the first filter screen 205 can be moved out of the first mounting rails 203. The first filter screen 205 can then be tilted and shaken or cleaned with a brush, causing impurities to fall directly to the ground. Or a garbage bag, to restore the permeability of the first filter screen 205 mesh, to avoid the impact of impurities on the subsequent filtration effect. The cleaning steps for the second filter screen 206 are the same as above. When the first filter screen 205 and the second filter screen 206 need to improve their filtration efficiency during the filtration process, first start the motor 37. The start of the motor 37 drives the cam 38 to rotate. The rotation of the cam 38 causes it to press against the T-shaped plate 34, causing the T-shaped plate 34 to move inside the groove 33. The movement of the T-shaped plate 34 inside the groove 33 drives the connecting rod 35 to move, connecting... The movement of rod 35 pushes the L-shaped bracket 5 to move inside the long groove 4. The movement of the L-shaped bracket 5 inside the long groove 4 drives the first filter screen 205 and the second filter screen 206 to move. At the same time, the movement of the L-shaped bracket 5 inside the long groove 4 also compresses the spring 32, causing the spring 32 to be compressed. When the cam 38 rotates and moves away from the T-shaped plate 34, the spring 32's rebound force causes the L-shaped bracket 5 to return to its original position. As the cam 38 continues to rotate, the first and second screens will move back and forth, accelerating the screening efficiency of fertilizer.
