Abstract

This invention relates to the field of soil pulverizing devices, and discloses an energy-saving soil pulverizing device and method for laboratory soil analysis. The device includes a pulverizing mechanism, a base, a housing fixedly connected to the top of the base, and a top plate fixedly connected to the top of the housing. Due to the limitation of a wide top opening and a narrow bottom opening at the feed inlet, when the slider moves downwards to the bottom, the slider drives an inclined plate to move downwards synchronously. The inclined plate, constrained by its inclined surface, applies a compressive force to the spring telescopic rod. At this time, the inclined plate contacts the side wall of the slider, sealing the feed inlet. After the inclined plate contacts the slider, the slider continues to move downwards. Due to the sealing effect, the inclined plate and slider, after moving downwards, compress the gas inside the housing. After being compressed, the gas passes through a pulverizing screen and several through holes. The sealing fit between the inclined plate and the slider can clean the soil blockages in the pulverizing screen and through holes during gas compression.

Description

Technical Field

[0001] This invention relates to the field of soil pulverizing equipment technology, specifically to an energy-saving soil pulverizing device and method for laboratory soil analysis. Background Technology

[0002] Soil analysis is the qualitative and quantitative determination of the composition and physical and chemical properties of soil. It is the foundation for research on soil formation and development, fertility evolution, soil resource evaluation, soil improvement and rational fertilization. It is also an important means of environmental quality assessment in environmental science. Before analyzing soil in the laboratory, the soil needs to be crushed.

[0003] When a soil pulverizer pulverizes soil, plant roots may be mixed in with the soil. These roots may clog the pulverizing screen, which can prevent the soil sample from being fully pulverized and affect the pulverizing efficiency. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an energy-saving soil pulverizing device for laboratory soil analysis, including a pulverizing mechanism, the pulverizing mechanism further including a base, a shell fixedly connected to the top of the base, and a top plate fixedly connected to the top of the shell.

[0005] The anti-accumulation mechanism also includes a circular plate fixedly connected to the bottom of the housing. The top of the circular plate has several through holes and several arc-shaped grooves. The bottom of the circular plate is fixedly connected to a discharge hood.

[0006] The sealing mechanism has two feed ports on the top of the top plate. Limiting grooves are provided on the side walls of the two feed ports. Limiting rods are fixedly connected inside the two limiting grooves. Slider blocks are slidably connected to the outer walls of the two limiting rods. The sliders are fixedly connected to the limiting grooves by springs. Movable grooves are provided on the side walls of the sliders.

[0007] Preferably, the crushing mechanism further includes a fixed frame fixedly connected to the top of the top plate. A hydraulic cylinder is fixedly connected to the bottom of the fixed frame. The output shaft of the hydraulic cylinder is slidably connected to the top of the top plate. A connecting block is fixedly connected to the output shaft of the hydraulic cylinder. Several connecting strips are rotatably connected to one side wall of the connecting block. Extrusion plates are rotatably connected to the sides of the several connecting strips that are far apart from each other. When the hydraulic cylinder is started, the hydraulic cylinder drives the connecting block to move up and down reciprocally. Using the force when the connecting block moves down, the connecting block moves down and then drives the several extrusion plates to move outward through the several connecting strips.

[0008] Preferably, the crushing mechanism further includes a crushing mesh fixedly connected to the top of the circular plate, a pusher plate fixedly connected to the bottom of the extrusion plate, and a pressure roller rotatably connected to the inner wall of the pusher plate. After several extrusion plates move outward, they drive several pusher plates and several pressure rollers to move outward. The outward movement of the extrusion plates and pusher plates can push the soil on the top of the circular plate into contact with the crushing mesh. After the soil comes into contact with the crushing mesh, it is pushed by the extrusion plates and pusher plates, forcing the soil to be squeezed and making full contact with the crushing mesh. This can effectively crush the soil. By pushing the soil towards the crushing mesh and applying pressure, the soil particles are crushed into uniform fine particles, which helps to accurately measure and analyze soil samples in laboratory analysis.

[0009] Preferably, the anti-stacking mechanism further includes a fixing block fixedly connected to the top of the circular plate, a rectangular block fixedly connected to the outer wall of the fixing block, the interior of the rectangular block being hollowed out, a sliding rod 1 fixedly connected to the side wall of the extrusion plate, the end of the sliding rod 1 away from the extrusion plate being slidably connected to the rectangular block, a connecting rod fixedly connected to the outer wall of the sliding rod 1, a push plate 2 fixedly connected to the end of the connecting rod away from the sliding rod 1, the top of the push plate 2 being slidably connected to the bottom of the rectangular block;

[0010] The sliding rod 1 slides through the outer wall of the rectangular block and extends into the interior of the fixed block. A limit plate is fixedly connected to the outer wall of the end of the sliding rod 1 inside the rectangular block. The limit plate is fixedly connected to the interior of the rectangular block by a spring. Utilizing the force of the extrusion plate moving outward, the extrusion plate moves outward, causing the sliding rod 1 to move outward. The outward movement of the sliding rod 1 then drives the push plate 2 to move outward via a connecting rod. The outward movement of the push plate 2 pushes the soil that has fallen between the push plate 1 and the push plate 2 outward. When the extrusion plate moves outward and pushes the soil into contact with the crushing mesh, the hydraulic cylinder then drives the connecting block 1... Moving upwards, the connecting block one moves upwards and then drives the extrusion plate to move inwards through several connecting strips. When the extrusion plate moves inwards, it drives the pressure roller to move inwards. When the pressure roller moves inwards, the push plate two pushes the soil between push plate one and push plate two outwards. After the pressure roller moves inwards, it can crush the soil that has been pushed out. After being crushed, the soil falls into the discharge hood through several through holes, thereby crushing the soil that the extrusion plate and push plate one cannot push. By crushing the soil by moving the pressure roller inwards, it can effectively crush the soil that the extrusion plate and push plate one cannot push, thus improving the crushing effect.

[0011] Preferably, the anti-accumulation mechanism further includes an impeller rotatably connected to the top of the fixed block. A cylinder is fixedly connected to the top of the impeller, and a groove is formed on the outer wall of the cylinder. A circular rod is fixedly connected to the side of the connecting block away from the hydraulic cylinder. A sliding rod is fixedly connected to the outer wall of the circular rod. The sliding rod is slidably connected to the groove. When the connecting block moves downward, it drives the circular rod to move downward. After the circular rod moves downward, it drives the sliding rod to move downward. After the sliding rod moves downward, it is restricted by the shape of the groove, which forces the cylinder to rotate. After the cylinder rotates, it drives the impeller to rotate. After the impeller rotates, the soil falling above the fixed block is thrown onto the circular plate. This facilitates the crushing of the soil by the extrusion plate, push plate, and pressure roller, preventing soil from accumulating on the surface of the fixed block and reducing the possibility of soil residue in the device. In this way, the residue of old soil is minimized each time the device crushes, effectively preventing the mixing of new soil with old soil. This helps to improve the purity of the new batch of soil, making the analysis results more accurate because the possibility of cross-contamination is significantly reduced, improving the consistency of the samples and helping to obtain more reliable results in the analysis process.

[0012] Preferably, the sealing mechanism further includes a spring telescopic rod fixedly connected to the inner wall of the movable groove. An inclined plate is fixedly connected to the end of the spring telescopic rod away from the movable groove. The side of the inclined plate away from the spring telescopic rod is slidably connected to the feed inlet. By utilizing the inclined arrangement of the feed inlet and the inclined plate, when the extrusion plate moves outward, it drives the connecting block two to move downward through the strip block. After the connecting block two moves downward, it drives the slider to slide downward in the feed inlet.

[0013] Preferably, the sealing mechanism further includes a connecting block two fixedly connected to the bottom of the slider. A strip block is rotatably connected to the side of the connecting block two away from the slider. The side of the strip block away from the connecting block two is rotatably connected to the extrusion plate. As the slider slides downward, it is restricted by the wide top opening and narrow bottom opening of the feed inlet. When the slider moves downward to the bottom, the slider drives the inclined plate to move downward synchronously. The inclined plate is restricted by the inclined surface and applies a compressive force to the spring telescopic rod. At this time, the inclined plate contacts the side wall of the slider and seals the feed inlet. After the inclined plate contacts the slider, the slider continues to move downward. Due to the sealing effect, the inclined plate and the slider compress the gas in the shell after moving downward. After being compressed, the gas in the shell passes through the crushing screen and several through holes. The sealing cooperation of the inclined plate and the slider can clean the soil blockage in the crushing screen and through holes when the gas is compressed. This can avoid the crushing screen and through holes from becoming blocked and ensure the efficiency of the device in crushing soil.

[0014] A pulverizing method for an energy-saving soil pulverizing device used in laboratory soil analysis includes the following steps:

[0015] S1: Start the hydraulic cylinder. The hydraulic cylinder drives the connecting block one to move up and down reciprocally. When the connecting block one moves down, it drives the circular rod to move down. After the circular rod moves down, it drives the sliding rod two to move down.

[0016] S2: After the connecting block moves downward, it drives several extrusion plates to move outward through several connecting strips. After the extrusion plates move outward, they drive several push plates and several pressure rollers to move outward.

[0017] S3: After sliding rod one moves outward, it drives push plate two to move outward through connecting rod. After push plate two moves outward, it can push the soil that has fallen between push plate one and push plate two outward.

[0018] S4: When the extrusion plate moves outward, it drives the connecting block 2 to move downward through the strip block. After the connecting block 2 moves downward, it drives the slider to slide downward in the limit groove.

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention utilizes the inclined arrangement of the feed inlet and the inclined plate. When the extrusion plate moves outward, it drives the connecting block two downward through the strip block. After the connecting block two moves downward, it drives the slider to slide downward in the limiting groove. While the slider slides downward, it is restricted by the wide opening at the top and narrow opening at the bottom of the feed inlet. When the slider moves downward to the bottom, the slider drives the inclined plate to move downward synchronously. The inclined plate is restricted by the inclined surface and applies a compressive force to the spring telescopic rod. At this time, the inclined plate contacts the side wall of the slider and seals the feed inlet. After the inclined plate contacts the slider, the slider continues to move downward. Due to the sealing effect, after the inclined plate and the slider move downward, they compress the gas in the shell. After the gas in the shell is compressed, it passes through the crushing screen and several through holes. The sealing cooperation of the inclined plate and the slider can clean the soil blockage in the crushing screen and through holes when the gas is compressed, avoiding the root system in the soil from clogging the crushing screen and through holes, thus ensuring the efficiency of the device in crushing soil.

[0021] 2. This invention utilizes the force exerted when the connecting block moves downwards. After the connecting block moves downwards, it drives several extrusion plates to move outwards via several connecting strips. The outward movement of the extrusion plates then drives several push plates and several pressure rollers to move outwards. The outward movement of the extrusion plates and push plates pushes the soil at the top of the circular plate into contact with the pulverizing mesh. After the soil comes into contact with the pulverizing mesh, it is pushed by the extrusion plates and push plates, forcing the soil to be compressed and ensuring full contact with the pulverizing mesh. This effectively pulverizes the soil. By pushing the soil towards the pulverizing mesh and applying extrusion pressure, the soil particles are pulverized into uniform fine particles, which helps in the accurate measurement and analysis of soil samples in laboratory analysis. In addition, the sealed fit between the inclined plate and the slider effectively prevents dust generated during soil pulverization, reducing dust pollution in the laboratory air and improving the air quality of the working environment.

[0022] 3. When this invention is used to crush soil, the soil to be crushed is first poured into the feed inlet, and then the hydraulic cylinder is activated. The hydraulic cylinder drives the connecting block one to move up and down reciprocally. When the connecting block one moves downward, it drives the circular rod downward. After the circular rod moves downward, it drives the sliding rod two downward. After the sliding rod two moves downward, it is restricted by the shape of the chute, which forces the cylinder to rotate. After the cylinder rotates, it drives the impeller to rotate. After the impeller rotates, the soil that falls above the fixed block is thrown onto the circular plate. This facilitates the crushing of the soil by the extrusion plate, push plate one, and pressure roller, preventing soil from accumulating on the surface of the fixed block and reducing the possibility of soil residue in the device. In this way, the residue of old soil is minimized each time the device crushes, effectively preventing the mixing of new soil with old soil, which helps to improve the purity of the new batch of soil and makes the analysis results more accurate. Because the possibility of cross-contamination is significantly reduced, the consistency of the sample is improved, and more reliable results are obtained in the analysis process.

[0023] 4. This invention utilizes the force exerted when the extrusion plate moves outward. After the extrusion plate moves outward, it drives the slide rod one to move outward. After the slide rod one moves outward, it drives the push plate two to move outward through the connecting rod. After the push plate two moves outward, it can push the soil that has fallen between the push plate one and the push plate two outward. When the extrusion plate moves outward and pushes the soil into contact with the crushing mesh, the hydraulic cylinder drives the connecting block one to move upward. After the connecting block one moves upward, it drives the extrusion plate to move inward through several connecting strips. When the extrusion plate moves inward, it drives the pressure roller to move inward. When the pressure roller moves inward, the push plate two pushes the soil between the push plate one and the push plate two outward. After the pressure roller moves inward, it can crush the pushed-out soil. After being crushed, the soil falls into the discharge hood through several through holes, thereby crushing the soil that the extrusion plate and the push plate one cannot push. By crushing the soil by the pressure roller moving inward, it can effectively crush the soil that the extrusion plate and the push plate one cannot push, thus improving the crushing effect.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1 - Figure 3 The present invention is an energy-saving soil pulverizing device for laboratory soil analysis, including a pulverizing mechanism 1, the pulverizing mechanism 1 further including a base 101, a shell 102 fixedly connected to the top of the base 101, and a top plate 103 fixedly connected to the top of the shell 102.

[0038] The anti-accumulation mechanism 2 also includes a circular plate 201 fixedly connected to the bottom of the housing 102. The top of the circular plate 201 has several through holes 202 and several arc grooves 203. The bottom of the circular plate 201 is fixedly connected to a discharge hood 23.

[0039] The sealing mechanism 3 has two feed ports 301 on the top of the top plate 103. Limiting grooves 32 are respectively provided on the side walls of the two feed ports 301. Limiting rods are fixedly connected inside the two limiting grooves 32. Sliding sliders 302 are slidably connected to the outer walls of the two limiting rods. The sliding sliders 302 are fixedly connected to the limiting grooves 32 by springs. Movable grooves 303 are provided on the side walls of the sliding sliders 302.

[0040] The crushing mechanism 1 also includes a fixed frame 104 fixedly connected to the top of the top plate 103. A hydraulic cylinder 105 is fixedly connected to the bottom of the fixed frame 104. The output shaft of the hydraulic cylinder 105 is slidably connected to the top of the top plate 103. A connecting block 106 is fixedly connected to the output shaft of the hydraulic cylinder 105. Several connecting strips 107 are rotatably connected to the side wall of the connecting block 106. Extrusion plates 108 are rotatably connected to the sides of the several connecting strips 107 that are far apart from each other. When the hydraulic cylinder 105 is started, the hydraulic cylinder 105 drives the connecting block 106 to move up and down reciprocally. Using the force when the connecting block 106 moves downward, the connecting block 106 moves downward and then drives the several extrusion plates 108 to move outward through the several connecting strips 107.

[0041] The pulverizing mechanism 1 also includes a pulverizing screen 109 fixedly connected to the top of the circular plate 201. A pusher plate 110 is fixedly connected to the bottom of the extrusion plate 108. A pressure roller 111 is rotatably connected to the inner wall of the pusher plate 110. After several extrusion plates 108 move outward, they drive several pusher plates 110 and several pressure rollers 111 to move outward. The outward movement of several extrusion plates 108 and pusher plates 110 can push the soil on the top of the circular plate 201 to contact the pulverizing screen 109. After the soil contacts the pulverizing screen 109, it is pushed by the extrusion plates 108 and pusher plates 110, forcing the soil to be squeezed and making the soil fully contact the pulverizing screen 109. This can effectively pulverize the soil. By pushing the soil towards the pulverizing screen 109 and applying pressure, the soil particles are pulverized into uniform fine particles, which helps to accurately measure and analyze soil samples in laboratory analysis.

[0042] Example 2, please refer to Figure 4 - Figure 9 This invention is an energy-saving soil pulverizing device for laboratory soil analysis. Based on Example 1, the anti-accumulation mechanism 2 further includes a fixing block 24 fixedly connected to the top of the circular plate 201. A rectangular block 204 is fixedly connected to the outer wall of the fixing block 24. The rectangular block 204 is hollowed out. A sliding rod 205 is fixedly connected to the side wall of the extrusion plate 108. The end of the sliding rod 205 away from the extrusion plate 108 is slidably connected to the rectangular block 204. A connecting rod 206 is fixedly connected to the outer wall of the sliding rod 205. A push plate 207 is fixedly connected to the end of the connecting rod 206 away from the sliding rod 205. The top of the push plate 207 is slidably connected to the bottom of the rectangular block 204.

[0043] The sliding rod 205 slides through the outer wall of the rectangular block 204 and extends into the interior of the fixed block 24. A limiting plate 213 is fixedly connected to the outer wall of the end of the sliding rod 205 inside the rectangular block 204. The limiting plate 213 is fixedly connected to the interior of the rectangular block 204 by a spring. Utilizing the force of the pressing plate 108 moving outward, the pressing plate 108 moves outward, causing the sliding rod 205 to move outward. After the sliding rod 205 moves outward, it drives the push plate 207 to move outward via the connecting rod 206. The push plate 207, after moving outward, pushes the soil that has fallen between the push plate 110 and the push plate 207 outward. When the pressing plate 108 moves outward and pushes the soil into contact with the crushing mesh 109, the hydraulic cylinder 105 drives the connecting rod 206 to... Connecting block 106 moves upward. After connecting block 106 moves upward, it drives the extrusion plate 108 to move inward through several connecting strips 107. When the extrusion plate 108 moves inward, it drives the pressure roller 111 to move inward. When the pressure roller 111 moves inward, the push plate 207 pushes the soil between push plate 110 and push plate 207 outward. After the pressure roller 111 moves inward, it can crush the pushed-out soil. After being crushed, the soil falls into the discharge hood 23 through several through holes 202, thereby crushing the soil that the extrusion plate 108 and push plate 110 cannot push. By crushing the soil by the inward movement of the pressure roller 111, the soil that the extrusion plate 108 and push plate 110 cannot push can be effectively crushed, thus improving the crushing effect.

[0044] The anti-accumulation mechanism 2 also includes an impeller 208 rotatably connected to the top of the fixed block 24. A cylinder 209 is fixedly connected to the top of the impeller 208. A groove 210 is provided on the outer wall of the cylinder 209. A circular rod 211 is fixedly connected to the side of the connecting block 106 away from the hydraulic cylinder 105. A sliding rod 212 is fixedly connected to the outer wall of the circular rod 211. The sliding rod 212 is slidably connected to the groove 210. When the connecting block 106 moves downward, it drives the circular rod 211 to move downward. After the circular rod 211 moves downward, it drives the sliding rod 212 to move downward. After the sliding rod 212 moves downward, it is constrained by the shape of the groove 210, which forces the cylinder 209 to rotate. After 209 rotates, it drives the impeller 208 to rotate. After the impeller 208 rotates, the soil falling above the fixed block 24 is thrown onto the circular plate 201. This facilitates the crushing of the soil by the extrusion plate 108, push plate 110, and pressure roller 111, preventing soil from accumulating on the surface of the fixed block 24 and reducing the possibility of soil residue in the device. Thus, the residual old soil is minimized each time the device crushes, effectively preventing the mixing of new and old soil, which helps to improve the purity of the new batch of soil and makes the analysis results more accurate. Because the possibility of cross-contamination is significantly reduced, the consistency of the samples is improved, and more reliable results are obtained in the analysis process.

[0045] The sealing mechanism 3 also includes a spring telescopic rod 304 fixedly connected to the inner wall of the movable groove 303. An inclined plate 305 is fixedly connected to one end of the spring telescopic rod 304 away from the movable groove 303. The side of the inclined plate 305 away from the spring telescopic rod 304 is slidably connected to the feed inlet 301. By utilizing the inclined arrangement of the feed inlet 301 and the inclined plate 305, when the extrusion plate 108 moves outward, the connecting block 2 306 is driven to move downward through the strip block 307. After the connecting block 2 306 moves downward, it drives the slider 302 to slide downward in the feed inlet 301.

[0046] The sealing mechanism 3 also includes a connecting block 306 fixedly connected to the bottom of the slider 302. A strip block 307 is rotatably connected to the side of the connecting block 306 away from the slider 302. The side of the strip block 307 away from the connecting block 306 is rotatably connected to the extrusion plate 108. As the slider 302 slides downward, it is restricted by the wide top opening and narrow bottom opening of the feed inlet 301. When the slider 302 moves downward to the bottom, the slider 302 drives the inclined plate 305 to move downward synchronously. The inclined plate 305 is restricted by the inclined surface and applies a compressive force to the spring telescopic rod 304. At this time, the inclined plate 305 contacts the side wall of the slider 302. The feed inlet 301 is sealed. After the inclined plate 305 contacts the slider 302, the slider 302 continues to move downward. Due to the sealing effect, after the inclined plate 305 and the slider 302 move downward, they compress the gas inside the housing 102. After being compressed, the gas inside the housing 102 passes through the crushing screen 109 and several through holes 202. The sealing cooperation between the inclined plate 305 and the slider 302 can clean the soil blockage in the crushing screen 109 and through holes 202 when the gas is compressed. This can avoid the crushing screen 109 and through holes 202 from becoming blocked, thus ensuring the efficiency of the device in crushing soil.

[0047] The pulverizing method of this pulverizing device includes the following steps:

[0048] S1: Start hydraulic cylinder 105. Hydraulic cylinder 105 drives connecting block 106 to move up and down reciprocally. When connecting block 106 moves down, it drives circular rod 211 to move down. After circular rod 211 moves down, it drives sliding rod 212 to move down.

[0049] S2: After the connecting block 106 moves downward, it drives several extrusion plates 108 to move outward through several connecting strips 107. After the extrusion plates 108 move outward, they drive several push plates 110 and several pressure rollers 111 to move outward.

[0050] S3: After sliding rod 1 205 moves outward, it drives push plate 2 207 to move outward through connecting rod 206. After push plate 2 207 moves outward, it can push the soil that has fallen between push plate 1 110 and push plate 2 207 outward.

[0051] S4: When the extrusion plate 108 moves outward, it drives the connecting block 2 306 to move downward through the strip block 307. After the connecting block 2 306 moves downward, it drives the slider 302 to slide downward in the limiting groove 32.

[0052] One specific application of this embodiment is:

[0053] When the device is used to crush soil, the soil to be crushed is first poured into the feed inlet 301, and then the hydraulic cylinder 105 is started. The hydraulic cylinder 105 drives the connecting block 106 to move up and down reciprocally. When the connecting block 106 moves downward, it drives the circular rod 211 to move downward. After the circular rod 211 moves downward, it drives the sliding rod 212 to move downward. After the sliding rod 212 moves downward, it is restricted by the shape of the sliding groove 210, which forces the cylinder 209 to rotate. After the cylinder 209 rotates, it drives the impeller 208 to rotate. After the impeller 208 rotates, the soil that falls above the fixed block 24 is thrown onto the circular plate 201. This makes it easier for the extrusion plate 108, the push plate 110 and the pressure roller 111 to crush the soil, preventing soil from accumulating on the surface of the fixed block 24 and reducing soil residue. The device effectively removes the residue of old soil each time it crushes, avoiding the mixing of new soil with old soil, which would affect the purity of the new batch of soil and ensure the consistency of the sample.

[0054] Utilizing the force exerted by the downward movement of connecting block 106, several connecting strips 107 drive several extrusion plates 108 to move outward. The outward movement of the extrusion plates 108 then drives several push plates 110 and several pressure rollers 111 to move outward. The outward movement of the extrusion plates 108 and push plates 110 pushes the soil at the top of the circular plate 201 into contact with the pulverizing mesh 109. After contact with the pulverizing mesh 109, the soil is further compressed by the extrusion plates 108 and push plates 110, ensuring full contact with the pulverizing mesh 109. This effectively pulverizes the soil. By pushing the soil towards the pulverizing mesh 109 and applying pressure, soil particles are pulverized into uniform, fine particles. This facilitates accurate measurement and analysis of soil samples in laboratory analysis.

[0055] Using the force of the extrusion plate 108 moving outward, the extrusion plate 108 moves outward, driving the slide rod 205 to move outward. The slide rod 205 then moves outward via the connecting rod 206, driving the push plate 207 to move outward. The push plate 207 then pushes the soil that has fallen between the push plate 110 and the push plate 207 outward. When the extrusion plate 108 pushes the soil into contact with the pulverizing screen 109, the hydraulic cylinder 105 drives the connecting block 106 to move upward. The upward movement of the connecting block 106 then drives the extrusion plate 108 to move inward via several connecting bars 107. When the extrusion plate 108 moves inward, it drives the pressure roller 111 to move inward. When the pressure roller 111 moves inward, the push plate 207 pushes the soil between the push plate 110 and the push plate 207 outward. After the pressure roller 111 moves inward, it can crush the pushed soil. After being crushed, the soil falls into the discharge hood 23 through several through holes 202, thereby crushing the soil that the extrusion plate 108 and the push plate 110 cannot push. By crushing the soil by the inward movement of the pressure roller 111, the soil that the extrusion plate 108 and the push plate 110 cannot push can be effectively crushed, thus improving the crushing effect.

[0056] By utilizing the inclined arrangement of the feed inlet 301 and the inclined plate 305, when the extrusion plate 108 moves outward, the connecting block 306 moves downward via the strip block 307. After the connecting block 306 moves downward, it drives the slider 302 to slide downward within the limiting groove 32. As the slider 302 slides downward, it is restricted by the wide top opening and narrow bottom opening of the feed inlet 301. When the slider 302 moves to the bottom, it drives the inclined plate 305 to move downward simultaneously. The inclined plate 305, constrained by its inclined surface, applies a compressive force to the spring telescopic rod 304. At this time, the inclined plate 305 contacts the side wall of the slider 302, sealing the feed inlet 301. After the inclined plate 305 contacts the slider 302, the slider 302 continues to move downward. Due to the sealing effect, after the inclined plate 305 and slider 302 move downward, they compress the gas inside the housing 102. After being compressed, the gas inside the housing 102 passes through the crushing mesh 109 and several through holes 202. The sealed cooperation between the inclined plate 305 and slider 302 can clean the soil blockage in the crushing mesh 109 and through holes 202 when the gas is compressed. This can avoid the crushing mesh 109 and through holes 202 from becoming blocked, ensuring the efficiency of the device in crushing soil. In addition, the sealed cooperation between the inclined plate 305 and slider 302 can effectively prevent the dust generated during soil crushing from being stirred up. It reduces dust pollution in the laboratory air and improves the air quality of the working environment.
