A soil-based spare screening device

Abstract

This invention belongs to the field of screening technology, specifically a soil-based standby screening device, including a screening box. A shearing module is located at the top center of the screening box, and a main body module is located at the center of the interior of the screening box. Washing modules are located at both ends of the main body module, and a decomposition module is located on one side of the washing modules. This invention adjusts the flow cross-sectional area between the water-saving ball and the elbow valve using a steering rod, thereby changing the flow rate and instantaneous impact force of the fluid sprayed onto the screen end face by the multi-mesh plate. This causes the interaction between the fluid and impurities and other solid particles inside the screen to change sinusoidally, i.e., intermittently adjusting the interaction between the fluid and the screen. This improves the removal effect of the fluid on impurities and other solid particles inside the screen, avoiding the compatibility issues caused by a single impact mode, and fully ensuring the smoothness of the screen mesh.

Description

Technical Field

[0001] This invention belongs to the field of screening technology, specifically relating to a soil-based standby screening device. Background Technology

[0002] Screening: Separating particles smaller than the screen aperture from the material entering the screen. It allows particles smaller than the screen aperture to pass through the screen, while retaining particles larger than the screen aperture.

[0003] Soil sieve: A form of screening and application scenario used to screen and classify soil and other particulate materials, reduce the interference of external impurities and other solid particles on the proportion of soil components, improve soil stability and cohesion, and at the same time, reduce the gaps between soil particles, improve the soil's own water retention capacity and aeration, so as to facilitate soil analysis, soil improvement, plant cultivation and product optimization.

[0004] As is well known, during long-term screening operations, impurities or other particles interact with the screen mesh. Acidic or alkaline substances on the surface of impurities or other solid particles continuously erode the inner wall of the screen mesh, reducing the roughness of the inner wall and increasing the screen mesh's ability to trap impurities. This leads to the deposition and blockage of impurities and solid particles inside the screen mesh, affecting the normal screening process and even changing the inner diameter of the screen mesh, essentially altering the screen's intended particle size and reducing the screening effect.

[0005] Based on the above problems, operators need to regularly disassemble and clean the screens in the screening equipment. The traditional screen cleaning method is as follows: the operator removes the screen from the main body of the screening equipment and knocks it on the outside of the main body of the screening equipment. During the knocking process, the knocking object generates an interaction force with the screen, and the impurities and other solid particles embedded in the mesh gain the kinetic energy to overcome the friction and cohesion between them and the screen until the impurities and solid particles are removed from the screen mesh.

[0006] However, while manual tapping has advantages such as energy saving and wide applicability, the tedious, repetitive, and monotonous process increases production costs and workload. In addition, due to the differences in friction and adhesion between impurities and other solid particles deposited inside different meshes of the screen and the screen itself, manual tapping inevitably leads to uncontrollable forces acting on the screen end face. This means that the forces acting on the screen end face may exceed the screen's load-bearing capacity, reducing the screen's lifespan and increasing screening costs. Furthermore, the manual tapping method is too monotonous and can easily lead to incompatibility between impurities and the screen, reducing the screening effect and failing to ensure complete removal of impurities and other solid particles from inside the screen mesh.

The hydration chamber and the screen are directly opposite each other. In addition, the cross-sectional width of the water tank is greater than the interface width of the hydration chamber.

[0056] A method for cleaning soil sieve mesh, using the aforementioned soil preparation screening device, comprises the following steps:

[0057] S1: First, the soil entering the hopper is initially cut by the rotating cutter driven by the roller. Then, the screen, washing module and decomposition module are divided into areas by the partition plate. At the same time, the soil output from the hopper is collected in a centralized manner by the low-level bin.

[0058] S2: Next, the washing module is driven by the single-sided base to reciprocate under the guidance of the single-sided rail. During this process, fluid is sprayed onto the end face of the screen through the hydration chamber, and the end face of the screen is cleaned by the rubber brush. The liquid on the end face of the screen is dried through the heat dissipation pipe. This process of alternating hot and cold operation is carried out on the impurities in the screen mesh to accelerate the rapid decomposition of the impurities.

[0059] S2: Finally, the Z-panel moving in opposite directions synchronously drives the rubber plate and smooth column to move towards the screen. The rubber plate provides covering support and pushes out the impurities in the screen mesh, and the interaction between the eccentric wheel and the coaxial disc causes the smooth column to continuously impact and crush the impurities protruding from the end face of the screen, further removing the impurities in the screen mesh.

[0060] The present invention has the following beneficial effects:

[0061] 1. This invention adjusts the flow cross-sectional area between the water-saving ball and the elbow water valve by adjusting the steering rod, thereby changing the fluid flow rate and instantaneous impact force sprayed onto the end face of the screen by the multi-mesh plate. This causes the interaction between the fluid and impurities and other solid particles inside the screen to change sinusoidally, that is, the interaction mode between the fluid and the screen is adjusted intermittently. This improves the removal effect of the fluid on impurities and other solid particles inside the screen, avoids the compatibility between the fluid and impurities and other solid particles caused by a single impact mode, and fully ensures the smoothness of the screen mesh.

[0062] 2. In this invention, the bridge frame drives the rubber plate towards the screen until the bridge frame contacts the end face of the screen. At this point, due to its own expansion and contraction properties, part of the rubber plate enters the inner wall of the screen mesh, and performs a certain degree of coating and ejection of impurities and other solid particles present in the screen mesh. To a certain extent, it can eject impurities and other solid particles that have not protruded from the screen mesh without damaging the inner wall of the screen mesh. At the same time, relative motion occurs between the eccentric wheel and the coaxial disk, and the smooth column moves towards the screen in a reciprocating manner. In this way, the smooth column can crush and decompose the impurities and other solid particles protruding from the screen mesh. Furthermore, due to the coating property of the rubber plate, the damage to the inner wall of the screen mesh caused by the expansion stress change or splashing of impurities and other solid particles when the smooth column crushes them can be reduced, thus increasing the service life of the screen.

[0063] 3. This invention uses a low-temperature fluid to flush away impurities and other solid particles in the screen mesh. Simultaneously, it utilizes heat exchange to cool the impurities and particles, causing localized shrinkage and affecting their internal structure. At the same time, the screen end face is dried via a heat dissipation pipe, while the impurities and particles in the mesh are heated, causing localized expansion of their internal structure. This combined water cooling and cooling process creates alternating hot and cold treatment of the impurities and particles. The continuous contraction and expansion of their internal structure during these temperature changes accelerates their decomposition and prevents direct hard contact between the smooth screen and impurities, thus increasing the screen's lifespan.

[0064] 4. This invention uses a rotary cutter to cut and decompose the soil inside the hopper. On the one hand, it enhances the shearing effect of the rotary cutter on the soil, avoids soil adhesion and blockage of the hopper outlet, ensures soil flowability, and improves the screening effect of the screen. On the other hand, while controlling the amount of soil flowing to the end face of the screen per unit time, it also adjusts the impact force between the soil and the screen per unit time, which helps to improve the service life of the screen.

[0087] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0088] It should be noted that the terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0089] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0090] Reference Figure 1 , Figure 2, Figure 4 and Figure 7 It is known that a soil preparation screening device includes a screening box 1, a shearing module 2 is provided at the top middle position of the screening box 1, a main body module 3 is provided at the middle position inside the screening box 1, a washing module 4 is provided at both ends of the main body module 3, and a decomposition module 5 is provided on one side of the washing module 4.

[0091] Reference Figure 1 , Figure 2 and Figure 3 It is known that the shearing module 2 includes: a hopper 21, which is snap-fitted and installed at the top center of the screening box 1, and the cross-sectional shape of the hopper 21 is an isosceles trapezoid; at least two rollers 22, which are evenly distributed between the vertical sections of the hopper 21 and are rotatably fitted with the hopper 21; a splitting cutter 23, which is evenly snap-fitted and distributed on the outer wall of the roller 22; a load-bearing plate 24, which is snap-fitted and installed in a through-type manner at one end of the hopper 21 near the centerline of the screening box 1; a leaf plate 25, which is detachably installed on the four corners of the end face of the load-bearing plate 24 away from the hopper 21 by bolts; earrings 26, which are snap-fitted and installed on the four corners of the end face of the load-bearing plate 24 away from the hopper 21; a straight rod 27, which is rotatably installed between two opposing earrings 26; a separating plate 28, which is fixedly installed at the middle position of the outer wall of the straight rod 27; and a torsion spring 29, which is snap-fitted and installed on the outer walls of both ends of the straight rod 27 and is located between the separating plate 28 and the earrings 26.

[0092] The tooth segments between adjacent rotary cutters 23 are staggered;

[0093] Reference Figure 1 , Figure 4 and Figure 5 It can be seen that the main module 3 includes: angle connecting rods 31, which are evenly inserted and installed in an array at the middle position of the inner walls on both sides of the screening box 1; two single-side rails 32, which are symmetrically distributed inside the screening box 1, and the single-side rails 32 are inserted and fitted with the angle connecting rods 31; hanging rods 33, which are evenly clamped and distributed at the middle position of the end face of the single-side rails 32 away from the hopper 21; a low-combination bin 34, which is one and is located at the end of the single-side rails 32 away from the hopper 21, and is fixedly installed with the hanging rods 33. In addition, the cross-sectional shape of the low-combination bin 34 is an isosceles trapezoid; and two side guard plates 35, which are symmetrically installed at the middle position of the inner walls on both sides of the screening box 1, and are perpendicular to each other with the single-side rails 32.

[0094] Screen 36 is inserted and installed in the middle of the screening box 1, and is detachably installed with the side guard plate 35 by bolts. The screen 36 has evenly distributed mesh in the middle and is made of steel plate. Single-sided base 37 is symmetrically slidably snapped and installed at both ends of single-sided rail 32. In addition, the single-sided base 37 is inserted and installed with the end rod. F-bracket 38 is symmetrically snapped and installed at both ends of the horizontal section of the single-sided base 37 near the end face of the hopper 21. Ball head column 39 is inserted and installed through the horizontal section of the F-bracket 38 and is snapped and installed with the single-sided base 37.

[0095] The end of the partition plate 28 away from the hopper 21 is tangent to the end face of the screen 36. The height of the ball head column 39 is greater than the end face of the single-sided base 37 near the hopper 21. The vertical distance between the end face of the low-level compartment 34 near the hopper 21 and the end face of the single-sided base 37 away from the hopper 21 is 10 centimeters.

[0096] The pretreatment process of the soil entering the hopper 21 by the shearing module 2:

[0097] The operator fills the hopper 21 with soil (during this process, the vibration of the hopper 21 during the material drop is reduced by the load plate 24, which enhances the stability and service life of the hopper 21). Then, the roller 22 drives the rotary cutter 23 to rotate, thereby cutting the soil inside the hopper 21. In practice, the roller 22 can be driven by an external motor to avoid soil sticking and ensure the flow of soil in the hopper 21 (and in practice, the vertical distance between adjacent rotary cutters 23 and the cutting thickness of the rotary cutter 23 can be adjusted according to the actual processing conditions).

[0098] It is hereby noted that the distribution area of ​​the mesh in the middle of the screen 36 is smaller than the cross-sectional area of ​​the opening at the end of the low-combination bin 34 near the hopper 21. This ensures that the soil after passing through the hopper 21 can be completely guided to the next stage, which helps to improve the cleanliness of the main body of the equipment.

[0099] The purpose of setting a vertical distance of 10 centimeters between the end face of the low-level concentrator 34 near the hopper 21 and the end face of the single-sided base 37 away from the hopper 21 is to avoid collision and interference between the single-sided base 37 and the low-level concentrator 34 when the washing module 4 and the decomposition module 5 are moved.

[0100] Single-sided base 37: Provides movement support and guidance for the washing module 4 and the decomposition module 5, and creates a stable installation environment;

[0101] Analysis of the movement process of the single-sided base 37 driving the washing module 4 and the decomposition module 5:

[0102] During the movement of the washing module 4 and the decomposition module 5 following the single-sided base 37 (in specific implementation, the single-sided base 37 can be driven to slide back and forth by an electric slider), the ball head column 39, driven by the F bracket 38, first contacts the partition plate 28, and lifts and flips the partition plate 28 towards the hopper 21 through the ball head column 39. In this way, the partition plate 28 avoids collision and limiting effect on the washing module 4 and the decomposition module 5 during the movement (the purpose of the partition plate 28 being tangent to the screen 36 is to prevent soil from flowing to the washing module 4 and the decomposition module 5 at both ends of the screen 36 when the screen 36 vibrates, that is, to isolate the flow channel between the screening area of ​​the screen 36 and the main body of the washing module 4 and the decomposition module 5, to ensure the complete screening of soil in the screening area of ​​the screen 36, which helps to improve the screening effect and ensures the overall cleanliness of the equipment).

[0103] The synergistic process and effect between the partition plate 28 and the same page plate 25:

[0104] When neither of the two ball-head columns 39 in a single-sided base 37 is in contact with the partition plate 28, the partition plate 28 rotates away from the hopper 21 under the restoring action of the torsion spring 29 until the partition plate 28 contacts the vertical section of the same plate 25 (at this time, the partition plate 28 and the end face of the screen 36 are perpendicular to each other).

[0105] Angle connecting rod 31 and hanging rod 33: The angle connecting rod 31 strengthens the connection stability between the single-sided base 37 and the screening box 1, thereby improving the accuracy of the operation between the washing module 4 and the decomposition module 5 and the screen 36; similarly, the hanging rod 33 provides a connection bridge between the low-combination chamber 34 and the single-sided base 37, avoiding the collision limit problem caused by the direct connection between the two (that is, the hanging rod 33 ensures that there is enough vertical space for the single-sided base 37 to move between the low-combination chamber 34 and the single-sided base 37).

[0106] Reference Figure 6 and Figure 7 It can be seen that the washing module 4 includes: arrow plates 41, two in a group, symmetrically distributed between two opposite single-sided bases 37, and corresponding one-to-one with the position of the support plate 51; connecting rods 42, symmetrically distributed at both ends of the arrow plates 41 on the side away from the center line of the screening box 1, and the connecting rods 42 are plugged into the single-sided bases 37; hydration chamber 43, plugged into the two connecting rods 42 near the end of the hopper 21; and elbow water valves 44, evenly snapped into the middle of the side wall of one end of the hydration chamber 43 in an array.

[0107] A band tube 45 is snap-fitted onto the inlet end of the elbow water valve 44; a cable tie ring 46 is positioned near the inlet end of the elbow water valve 44, and each cable tie ring 46 is plugged into the band tube 45 on the same side; a steering rod 47 is rotatably mounted in the middle of the hydration chamber 43; water-saving balls 48 are evenly distributed on the outer wall of the steering rod 47 and correspond one-to-one with the position of the elbow water valve 44 to control the water output of the elbow water valve 44; a water distribution plate 49 is snap-fitted onto the middle of the bottom wall of the hydration chamber 43, and the vertical distance between the end of the water distribution plate 49 near the water-saving ball 48 and the water-saving ball 48 is five centimeters.

[0108] Reference Figure 4 , Figure 5 and Figure 6 It can be seen that a water tank 411 is snapped between the two connecting rods 42 at the end away from the hopper 21, and the cross-sectional shape of the water tank 411 is an isosceles trapezoid. A U-shaped frame 412 is snapped inside the water tank 411. A filter screen 413 is snapped on the end face of the U-shaped frame 412 away from the hydration chamber 43. A liquid sealing chamber 414 is snapped on the outer wall of the end of the water tank 411 away from the hydration chamber 43, and the vertical distance between the liquid sealing chamber 414 and the filter screen 413 is 10 centimeters. Drain valves 415 are evenly distributed in the middle position of the end face of the liquid sealing chamber 414 away from the hydration chamber 43.

[0109] Reference Figure 2 and Figure 8 It is known that a rubber brush 431 is rotatably installed inside the hydration chamber 43 near the center line of the screen 36, and the movement trajectory of the rubber brush 431 intersects with that of the screen 36. The outer walls of both ends of the rubber brush 431 and the outer walls of both ends of the steering rod 47 are fitted with mutually cooperating pulleys 432, which are driven by belts. A multi-mesh plate 433 is installed in the half area of ​​the hydration chamber 43 near the screen 36. An end guard plate is installed on the end face of the hydration chamber 43 near the center line of the screen 36, and a heat dissipation pipe 435 is rotatably installed between the end guard plates. A transfer pipe 436 that is plugged into the screen 36 is movably installed at the end of the cable tie ring 46 away from the hydration chamber 43, and the cross-sectional shape of the transfer pipe 436 is L-shaped. A traction rope 437 that is fixedly connected to the same band tube 45 is slidably fitted at the axis of the transfer pipe 436. A counterweight block 438 is fitted at the end of the traction rope 437 away from the screen 36.

[0110] The vertical distance between the end of the hydration chamber 43 near the screen 36 and the screen 36 is five centimeters. The vertical distance between the end of the water tank 411 near the screen 36 and the screen 36 is also five centimeters. The hydration chamber 43 and the screen 36 are directly opposite each other. In addition, the cross-sectional width of the water tank 411 is greater than the interface width of the hydration chamber 43.

[0111] The washing module 4 removes impurities and other solid particles from the 36-mesh sieve:

[0112] First, by rotating the steering rod 47 (in specific implementation, the steering rod 47 can be rotated by an external micro motor to a specified angle), the cross-sectional area of ​​the connection between the water-saving ball 48 and the water outlet of the elbow valve 44 is adjusted (in specific implementation, the corresponding fluid can be supplied to the waveband pipe 45 through an external pipe). This changes the flow rate and instantaneous impact force of the fluid sprayed by the multi-mesh plate 433 onto the end face of the screen 36, so that the interaction between the fluid and the impurities and other solid particles inside the screen 36 changes in a sinusoidal function. That is, the degree of interaction between the fluid and the screen 36 is adjusted intermittently, thereby improving the removal effect of the fluid on the impurities and other solid particles inside the screen 36, avoiding the compatibility between the fluid and the impurities and other solid particles caused by a single impact form, and fully ensuring the smoothness of the mesh of the screen 36.

[0113] Next, the impurities and other solid particles on the end face and inside the mesh of the screen 36 are scraped off by the rubber brush 431 to ensure the cleanliness of the end face and inside the mesh of the screen 36. (The water-saving ball 48 inside the hydration chamber 43 controls the flow of fluid to both ends of the water distribution plate 49. On the one hand, it achieves a stable water supply to the area of ​​the multi-mesh plate 433. On the other hand, it provides self-cleaning spray water to the rubber brush 431, which helps to ensure the long-term effectiveness of the rubber brush 431.)

[0114] Finally, the liquid sprayed from the hydration chamber 43 onto the end face of the drying screen is collected by the water tank 411 (both the hydration chamber 43 and the water tank 411 are a certain distance away from the screen 36: the purpose is to avoid interference between the screen 36 and the hydration chamber 43 and the water tank 411; thereafter, the liquid flows into the water tank 411 under the action of gravity. In order to ensure the complete collection of the liquid sprayed from the hydration chamber 43 by the water tank 411, in specific implementation, the cross-sectional width of the water tank 411 is controlled to be greater than the cross-sectional width of the hydration chamber 43, so as to avoid the liquid splashing to other areas).

[0115] During this process, the wastewater is initially filtered through the built-in filter screen 413 (the filter screen 413 is removable by the U-shaped frame 412, which facilitates disassembly and maintenance in the future). Finally, the liquid accumulated inside the sealed liquid chamber 414 is discharged to the outside through the drain valve 415. In specific implementation, the above-mentioned wastewater can be discharged through the cooperation between the external hose and the water pump.

[0116] Solution to the problem of disordered distribution of band tubes 45 within screening box 1 due to the mobility of hydration chamber 43:

[0117] When the hydration chamber 43 moves toward the center line of the screen 36:

[0118] The band tube 45 moves synchronously with the water tank 43 towards the center line of the screen 36. At this time, the band tube 45 on the same side moves in an orderly manner under the restraint of the wire ring 46. At this time, the traction rope 437 drives the counterweight 438 to move towards the hopper 21 under the traction of the band tube 45.

[0119] When the hydration chamber 43 moves toward both ends of the screen 36:

[0120] The counterweight 438 pulls the traction rope 437, and then the traction rope 437 pulls the band tube 45 in the opposite direction during the movement until the band tube 45 retracts back into the vertical section of the adapter tube 436.

[0121] Pulley 432: By driving the steering rod 47 and the rubber brush 431 to share the same drive source, it helps to save energy and improve electrical safety;

[0122] Connecting rod 42 and arrow plate 41: Through the cooperation between connecting rod 42 and arrow plate 41, the hydration chamber 43 and water tank 411 can move synchronously with the single-sided base 37 to the designated position, which helps to enhance the linkage and correlation between the single-sided base 37 and the washing module 4.

[0123] Heat dissipation pipe 435: While drying the end face of the screen 36 after water washing, the heat dissipation pipe 435 also heats the impurities and other solid particles in the mesh of the screen 36, causing local expansion of the internal structure of the impurities and other solid particles. In addition to water cooling, the impurities and other solid particles are processed by alternating hot and cold. Through the continuous contraction and expansion of the internal structure of the impurities and other solid particles during the hot and cold changes, their decomposition is accelerated. At the same time, it avoids direct hard contact between the smooth column 583 and the impurities, thus increasing the service life of the screen 36.

[0124] Reference Figure 2 , Figure 9 and Figure 11 It can be seen that the decomposition module 5 includes: support plates 51, two in a group, symmetrically distributed at both ends inside the screening box 1; gears 52, rotatably mounted on the end face of the support plates 51 away from the centerline of the screening box 1 via a rotating shaft; racks 53, two in a group, slidably and interlocked on the end face of each support plate 51 away from the centerline of the screening box 1, and the racks 53 mesh with the gears 52; and a Z-panel 54, coaxially mounted on the end of the racks 53 away from the gears 52, and slidably and interlocked with the support plates 51.

[0125] The notched wheel 55 is slidably snapped into the middle position at both ends of the support plate 51 and is rotatably fitted with the Z-panel 54; the cable tray 56 is snapped into the bottom ends of the two opposing support plates 51; the rubber plate 57 is snapped into the middle position of the end face of the cable tray 56 near the centerline of the support plate 51; the notched frame 58 is installed by a connecting pin at the end of the two opposing support plates 51 away from the rubber plate 57; the eccentric wheel 59 is rotatably fitted between the vertical sections of the notched frame by a connecting rod and is plugged into the notched wheel 55.

[0126] Reference Figure 10 and Figure 11 It can be seen that the horizontal section of the mouthpiece frame 58 has spring rods 581 evenly distributed in a through pattern, and the spring rods 581 are slidably installed with the mouthpiece frame 58. All the spring rods 581 are installed with a shovel plate 582 at the end near the center line of the support plate 51. The end of the shovel plate 582 away from the mouthpiece frame 58 is rotatably installed with a smooth column 583. Both ends of the smooth column 583 have a shaft disc 584 that cooperates with the eccentric wheel 59. The thickness of the shaft disc 584 is greater than the thickness of the eccentric wheel 59. Both ends of the smooth column 583 are installed with a shaft disc 584 that cooperates with the eccentric wheel 59. An ohmic lock 585 is slidably engaged with the support plate 51, and the vertical distance between the ohmic lock 585 and the support plate 51 is less than the vertical distance between the shaft disc 584 and the support plate 51. Both horizontal sections of the ohmic lock 585 are fixedly installed with slide rods 586 that are slidably engaged with the Z-panel 54 at the corresponding positions. The outer wall of the slide rod 586 is fitted with a return spring 587 located between the ohmic lock 585 and the Z-panel 54. The end face of the support plate 51 away from the center line of the screening box 1 is symmetrically fixedly installed with end rods.

[0127] The process of the smooth column 583 and the rubber plate 57 moving towards the screen 36:

[0128] Two centrally symmetrical racks 53, under the meshing action of gear 52, respectively drive the Z panel 54 to move towards or away from each other to a designated position;

[0129] At this time, one of the Z-panels 54 drives the bridge frame 56 to move towards the screen 36 until the bridge frame 56 contacts the end face of the screen 36. At this time, the rubber plate 57 contacts the screen 36. Due to the elasticity of the rubber plate 57, part of the rubber plate 57 enters the mesh of the screen 36. (The softness of the rubber plate 57 will cause it to cover and push out impurities and other solid particles inside the mesh of the screen 36 to a certain extent. Its softness can also adapt to the expansion and contraction of impurities during temperature changes, which helps to protect the integrity of the mesh of the screen 36 and enhance the service life of the screen 36.)

[0130] At the same time, another Z-panel 54 synchronously drives the notched wheel 55 to move towards the screen 36 until the smooth column 583 contacts the end face of the screen 36 (the smooth column 583 is used to crush the impurities protruding from the end face of the screen 36, reducing the crushing area and enhancing the crushing effect; it should be noted that while the smooth column 583 is crushing the impurities, the rubber plate 57 provides covering support for the impurities, thereby avoiding direct rigid contact between the impurities and the screen 36, and the aforementioned alternating hot and cold operation also helps to accelerate the crushing and decomposition of impurities by the smooth column 583).

[0131] During this process, the linkage between the slide bar 586 and the ohmic lock 585, and between the shovel plate 582 and the smooth column 583, causes the smooth column 583 to move synchronously with the Z panel 54 toward the screen 36. When the smooth column 583 moves to a certain height from the screen 36, the concave wheel 55 drives the eccentric wheel 59 to rotate (in specific implementation, the concave wheel 55 can be driven to rotate by an external motor). Under the action of the eccentric wheel 59, the shaft disc 584 causes the smooth column 583 to continuously reciprocate with the screen 36 (the elasticity of the return spring 587 and the spring rod 581 provides a buffer for the rebound of the smooth column 583, reduces the kinetic energy of the smooth column 583 during the recovery process, and improves its service life). In this way, the smooth column 583 impacts, crushes, and decomposes the protruding impurities of the screen 36.

[0132] End rod: Provides stable support between the disassembly module 5 and the single-sided base 37.

[0133] The working principle of the soil preparation screening device provided by the present invention is as follows: First step: First, the rotating cutter 23 driven by the roller 22 performs preliminary cutting on the soil entering the hopper 21. Then, the screen 36, washing module 4 and decomposition module 5 are divided and managed by the partition plate 28. At the same time, the soil output from the hopper 21 is collected centrally by the low-level bin 34.

[0134] Step 2: Next, the washing module 4 is driven by the single-sided base 37 to reciprocate under the guidance of the single-sided rail 32. During this process, fluid is sprayed onto the end face of the screen 36 through the hydration chamber 43, and the end face of the screen 36 is cleaned by the rubber brush 431. The liquid on the end face of the screen 36 is dried through the heat dissipation pipe 435. This process of alternating hot and cold treatment is carried out on the impurities in the mesh of the screen 36 to accelerate the rapid decomposition of the impurities.

[0135] Step 3: Finally, the Z-panel 54, moving in opposite directions, synchronously drives the rubber plate 57 and the smooth column 583 towards the screen 36. The rubber plate 57 provides covering support and pushes out the impurities in the mesh of the screen 36. The interaction between the eccentric wheel 59 and the coaxial disk 584 causes the smooth column 583 to continuously impact and crush the impurities protruding from the end face of the screen 36, further removing the impurities in the mesh of the screen 36.
