Description

Technical Field

[0001] The present invention relates to the technical field of soil sample separation, and specifically to a soil sample separation device for detecting soil microorganisms. Background Art

[0002] Soil microorganisms are the general term for bacteria, fungi, actinomycetes, and algae living in the soil, and they are tiny in size. The types and quantities of soil microorganisms vary with the soil-forming environment and the depth of soil layers. They carry out processes such as oxidation, nitrification, ammonification, nitrogen fixation, and sulfidation in the soil, promoting the decomposition of soil organic matter and the transformation of nutrients. Generally, the number of bacteria in the soil is the largest. Beneficial bacteria include nitrogen-fixing bacteria, nitrifying bacteria, and saprophytic bacteria; harmful bacteria include denitrifying bacteria, etc. When sampling these microorganisms, it is necessary to ensure that the samples are not contaminated. Soil microorganism detection refers to quantifying, identifying, and evaluating the types, quantities, activities, functions, and other characteristics of microbial communities in the soil through a series of scientific methods and technical means. This information is of great significance for understanding soil health status, evaluating soil fertility, predicting soil productivity, monitoring environmental pollution, guiding agricultural management practices, and studying soil ecosystem processes. However, after taking soil samples, they cannot be directly detected, and the soil samples need to be processed, thus requiring the use of soil sample processing equipment.

[0003] Currently, the existing dried soil will adhere together to form mud masses, which is inconvenient for preprocessing the mud masses. At the same time, there will be blocky sundries in the soil samples, which is inconvenient for processing the blocky sundries, and thus is not conducive to improving the purity of the soil and affects subsequent soil microorganism detection. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A soil sample separation device for detecting soil microorganisms, comprising: A housing, which is a shell with a supporting function. An inlet assembly is installed at the middle of the top of the housing, and an outlet is installed at the bottom of the housing; A pretreatment mechanism, which is used for crushing the soil sample, and the pretreatment mechanism is installed inside the housing; Among them, the pretreatment mechanism includes a cylinder and a fixed plate. The cylinder is fixedly installed at the side of the inner cavity of the housing, and the cylinder is installed near the top of the housing. The fixed plate is fixedly installed at the middle of the top of the inner cavity of the housing. The output end of the cylinder is fixedly installed with a moving plate, and the position of the moving plate corresponds to the position of the fixed plate. A semi-circular convex block is fixedly connected to the outside of the moving plate and near the bottom position. A rectangular notch is opened at the bottom of the fixed plate, and an adjusting component is installed at the middle of the outside of the fixed plate. By extending and contracting the output end of the cylinder, the moving plate can be driven to move reciprocally; When the moving plate approaches the fixed plate, the soil sample that has fallen between the moving plate and the fixed plate at this time will be squeezed, so that the mud mass formed by the dry soil adhering together will be subjected to a squeezing force, and the mud mass will be broken in time, thereby preprocessing the soil sample; The soil sample separation device for detecting soil microorganisms further includes: A separation mechanism for processing sundries, and the separation mechanism is installed in the middle of the inner part of the housing; Among them, the separation mechanism includes a support frame and a servo motor. The support frame is installed in the middle of the inner part of the housing. The top end of the support frame penetrates through the housing and extends to the outside. The servo motor is installed on the side of the outside of the support frame. Rotating rollers are rotatably installed at both ends of the support frame. The output end of the servo motor is fixedly installed with the rotating roller through a coupling. Conveyor belts are installed at the corresponding positions of the rotating rollers. Round rods are fixedly installed at the outer edges of the conveyor belts, and stirring teeth are fixedly installed in the middle of the outer sides of the conveyor belts. By using the rotation of the output end of the servo motor, the rotating roller can be driven to rotate clockwise, so that the conveyor belt drives the round rod and the stirring teeth to operate. At this time, the block sundries in the soil sample can be intercepted by the round rods evenly distributed on the outer side of the conveyor belt, and the crushed soil falls from the space between two adjacent round rods; With the continuous operation of the conveyor belt driving the round rod, the intercepted block sundries can be transported out of the interior of the housing, thereby separating the soil and the block sundries.

[0005] Preferably, the moving plate is installed obliquely, and the semi-circular convex blocks are evenly distributed on the outer side of the moving plate, and the diameter of the semi-circular convex blocks gradually increases from top to bottom. By using the inclined installation of the cylinder, when the output end of the cylinder extends to push the moving plate, the moving plate can be moved right upwards, and then through the cooperation between the moving plate and the fixed plate, the soil sample can be kneaded and squeezed, which helps to preprocess the soil sample; At the same time, by using the semi-circular convex blocks evenly distributed on the outer side of the moving plate, and the diameter of the semi-circular convex blocks gradually increases from top to bottom, the friction force on the soil sample is increased, which helps to break it.

[0006] Preferably, the adjusting assembly includes a guide rod. The top end of the guide rod is fixedly installed at a position corresponding to the outside of the fixed plate. A connecting sliding sleeve is slidably installed at the bottom end of the guide rod. A spring is fixedly installed between the upper end surface of the connecting sliding sleeve and the outside of the guide rod. The guide rod passes through the center of the spring. A flat baffle is fixedly installed on the outside of the connecting sliding sleeve. Force-receiving blocks are fixedly installed at positions corresponding to the outside of the flat baffle. The positions of the force-receiving blocks correspond to the positions of the stirring teeth. When the conveyor belt drives the stirring teeth to operate, at this time, the stirring teeth at the top of the conveyor belt move right upwards; The toggle teeth are in contact with the force block, and as the toggle teeth continue to move, the force block is subjected to an upward force, which is then transmitted to the plane baffle. Under the guidance of the guide rod and the sliding connection of the connecting sleeve, the plane baffle moves upward, and the spring is compressed, thereby opening the rectangular gap, which can increase the leakage of the crushed soil sample and prevent material accumulation. As the toggle tooth separates from the force-bearing block, the jacking force on the force-bearing block disappears, and under the elastic force provided by the spring, the plane baffle moves downward to reset, and then the plane baffle moves back and forth up and down to promote the leakage of crushed soil.

[0007] Preferably, the planar baffle is parallel to the fixed plate to facilitate the movement of the fixed plate, and the plane outside the fixed plate is in contact with the plane outside the fixed plate.

[0008] Preferably, there are two support frames, and the two support frames are symmetrically installed along the round rod, and the support frames are installed at an angle.

[0009] Preferably, there are two conveyor belts, and the two conveyor belts are symmetrically installed along the round rod. The two symmetrical conveyor belts are used for transmission, so that the round rod runs smoothly. The shifting teeth are evenly distributed in the middle of the outer side of the conveyor belt, and the shifting teeth are staggered with the round rod.

[0010] Preferably, the feeding assembly includes a conical hopper, which is fixedly installed at the middle of the top of the shell by screws, and the bottom end of the conical hopper passes through the top of the shell and extends into the interior thereof, and a guide plate is fixedly installed at the edge of the bottom of the conical hopper, and the guide plate is installed directly above the fixed plate, and a swing plate is hingedly connected to the bottom of the conical hopper and the side away from the guide plate, and the swing plate is installed directly above the movable plate, and piercing pieces are fixedly installed at corresponding positions on the outer side of the swing plate, and as the soil sample falls and the guide plate is installed at an angle, the soil sample will be guided by the guide plate, so that the soil sample can smoothly enter between the fixed plate and the movable plate, so that the soil sample will not be scattered at will.

[0011] When the movable plate is pushed to the upper right by the output end of the cylinder, the top of the movable plate applies a driving force to the swing plate, so that the swing plate can swing counterclockwise to adjust the angle, thereby blocking the bottom end of the conical hopper and reducing the amount of soil sample raw materials leaking downward; When the moving plate is driven to and fro by the output end of the cylinder, the swing plate can swing to and fro, thereby controlling the amount of soil sample material leaking downward, and the structures are linked together by utilizing the interaction between the structures.

[0012] Preferably, the guide plate and the swing plate are installed at an angle, and the puncture piece is installed just below the leakage port at the bottom of the conical hopper. When the swing plate is pushed by the top of the movable plate to rotate and adjust the angle, the puncture piece will rotate with the swing plate, thereby puncturing the soil-like raw materials in the conical hopper, so that the soil-like raw materials are not easy to adhere together and are not easy to get blocked.

[0013] Preferably, a secondary processing component is installed inside the shell, and the secondary processing component is installed at a position close to the bottom of the shell, and the secondary processing component includes a supporting frame, the edge of the outer side of the supporting frame is fixedly installed with the inner wall of the shell, a screen is fixedly installed in the middle of the top of the supporting frame, a zigzag frame is fixedly installed at the side of the top of the supporting frame, and the top of the zigzag frame is hinged with a hook plate, the position of the hook plate corresponds to the position of the toggle tooth, a diamond-shaped elastic frame is fixedly installed between the two sides of the outer side of the hook plate corresponding to the inner wall of the shell, and a percussion hammer is fixedly installed at the bottom end of the hook plate, and after the block debris is separated from the crushed soil, the crushed soil falls onto the screen, and the screen filters out the granular stones in the crushed soil, while the crushed soil continues to leak down and is discharged from the discharge port; At the same time, the conveyor belt is used to drive the toggle teeth to operate. At this time, the toggle teeth at the bottom of the conveyor belt contact the top of the hook plate, and the top of the hook plate is pushed downward to the left, so that the hook plate drives the hammer to rotate counterclockwise, and the diamond elastic frame is compressed; As the toggle tooth continues to move, the toggle tooth disengages from the top of the hook plate. At this time, the driving force on the hook plate disappears, and under the elastic force of the diamond-shaped elastic frame, the hook plate drives the knocking hammer to rotate clockwise to reset, so that the bottom end of the knocking hammer knocks on the screen, causing the screen to vibrate, thereby promoting the screening of the soil sample.

[0014] Preferably, the hook plate and the percussion hammer are both installed at an angle, and the percussion hammer is installed directly above the screen.

[0015] The present invention provides a soil sample separation device for detecting soil microorganisms. It has the following beneficial effects: 1. The soil sample separation equipment for detecting soil microorganisms utilizes the extension and contraction of the cylinder output end to drive the movable plate to move back and forth. When the movable plate approaches the fixed plate, the soil sample falling between the movable plate and the fixed plate will be squeezed, and then the mud mass attached to the dry soil will be squeezed, and the mud mass will be broken in time, thereby pre-treating the soil sample.

[0016] 2. The soil sample separation equipment for detecting soil microorganisms uses a cylinder for tilted installation. When the movable plate is pushed by extending the output end of the cylinder, the movable plate can be moved to the upper right, and then the movable plate and the fixed plate can cooperate with each other to knead and squeeze the soil sample, which is helpful for pre-treatment of the soil sample. At the same time, semicircular protrusions are evenly distributed on the outside of the movable plate, and the diameter of the semicircular protrusions gradually increases from top to bottom, so that the friction force on the soil sample is increased, which is helpful for crushing.

[0017] 3. The soil sample separation equipment for detecting soil microorganisms can intercept block debris in the soil sample by using round rods evenly distributed on the outside of the conveyor belt, and the broken soil falls from the space between two adjacent round rods. As the conveyor belt drives the round rods to continuously rotate, the intercepted block debris can be transported out of the inner shell, thereby separating the soil and the block debris.

[0018] 4. The soil sample separation equipment for detecting soil microorganisms, as the toggle teeth apply an upward pushing force to the force-bearing block, the plane baffle moves upward, and the spring is compressed, thereby opening the rectangular gap, which can increase the leakage of the crushed soil sample and make it less likely for material to accumulate. As the toggle teeth are separated from the force-bearing block, the pushing force on the force-bearing block disappears, and under the action of the elastic force provided by the spring, the plane baffle moves downward to reset, and then the plane baffle moves back and forth up and down to promote the leakage of crushed soil.

[0019] 5. The soil sample separation equipment for detecting soil microorganisms puts the soil sample into a conical hopper and then loads the soil sample. As the soil sample falls, the guide plate is installed obliquely. At this time, the soil sample will be guided by the guide plate, so that the soil sample can smoothly enter between the fixed plate and the movable plate, so that the soil sample will not be scattered at will.

[0020] 6. The soil sample separation equipment for detecting soil microorganisms uses the output end of the cylinder to push the moving plate to the upper right. At this time, the top of the moving plate applies a driving force to the swinging plate, which can make the swinging plate swing counterclockwise to adjust the angle, so as to block the bottom end of the conical hopper, thereby reducing the amount of soil sample raw materials leaking down. When the moving plate is driven to reciprocate by the output end of the cylinder, the swinging plate can swing back and forth, thereby controlling the amount of soil sample raw materials leaking down.

[0021] 7. The soil sample separation equipment for detecting soil microorganisms uses the swing plate to rotate and adjust the angle when it is pushed by the top of the moving plate. At this time, the piercing piece will rotate with the swing plate, and then pierce the soil sample raw materials in the conical hopper, so that the soil sample raw materials are not easy to adhere together and are not easy to be blocked.

[0022] 8. The soil sample separation equipment for detecting soil microorganisms uses a screen to filter out the granular stones in the crushed soil, and uses the top of the hook-shaped plate to be pushed to the lower left, so that the hook-shaped plate drives the knocking hammer to rotate counterclockwise, and as the pushing force on the hook-shaped plate disappears, and under the elastic force of the diamond-shaped elastic frame, the hook-shaped plate drives the knocking hammer to rotate clockwise to reset, and then the bottom end of the knocking hammer knocks on the screen, causing the screen to vibrate, thereby promoting the screening of the soil sample.

The present invention provides a technical solution: a soil sample separation device for detecting soil microorganisms, including: A housing 1, the housing 1 having a shell with a supporting function, a feeding assembly 2 is installed at the middle of the top of the housing 1, and a discharge port 3 is installed at the bottom of the housing 1; A pretreatment mechanism 4, the pretreatment mechanism 4 is used for crushing the soil sample, and the pretreatment mechanism 4 is installed inside the housing 1; Among them, the pretreatment mechanism 4 includes a cylinder 41 and a fixed plate 42. The cylinder 41 is fixedly installed at the side of the inner cavity of the housing 1, and the cylinder 41 is installed near the top of the housing 1. The fixed plate 42 is fixedly installed at the middle of the top of the inner cavity of the housing 1. The output end of the cylinder 41 is fixedly installed with a moving plate 43. The position of the moving plate 43 corresponds to the position of the fixed plate 42. A semi-circular convex block 44 is fixedly connected to the outside of the moving plate 43 and near the bottom position. A rectangular notch 45 is opened at the bottom of the fixed plate 42. An adjusting assembly 46 is installed at the middle of the outside of the fixed plate 42. The staff turns on the cylinder 41 to work. By using the extension and contraction of the output end of the cylinder 41, the moving plate 43 can be driven to move reciprocally. When the moving plate 43 approaches the fixed plate 42, the soil sample that falls between the moving plate 43 and the fixed plate 42 at this time will be squeezed, so that the mud mass attached to the dry soil is subjected to a squeezing force, and the mud mass is broken in time; The moving plate 43 is inclinedly installed, and the semi-circular convex blocks 44 are evenly distributed on the outside of the moving plate 43, and the diameter of the semi-circular convex blocks 44 gradually increases from top to bottom. By using the inclined installation of the cylinder 41, when the output end of the cylinder 41 extends to push the moving plate 43, the moving plate 43 can be moved upward and to the right, and then through the cooperation between the moving plate 43 and the fixed plate 42, the soil sample can be kneaded and squeezed, which helps to pre-treat the soil sample; At the same time, by using the semi-circular convex blocks 44 evenly distributed on the outside of the moving plate 43, and the diameter of the semi-circular convex blocks 44 gradually increases from top to bottom, the friction force on the soil sample is increased.

[0027] The soil sample separation device for detecting soil microorganisms further includes: Separation mechanism 5, which is used to process sundries, and the separation mechanism 5 is installed in the middle inside the housing 1; Among them, the separation mechanism 5 includes a support frame 51 and a servo motor 52. The support frame 51 is installed in the middle inside the housing 1. The top of the support frame 51 penetrates the housing 1 and extends to its outside. The servo motor 52 is installed on the side of the outside of the support frame 51. Rotating rollers 53 are rotatably installed at both ends of the support frame 51. The output end of the servo motor 52 is fixedly installed with the rotating roller 53 through a coupling. Conveyor belts 54 are installed at the corresponding positions of the rotating rollers 53. Round rods 55 are fixedly installed at the outer edges of the conveyor belts 54. Poking teeth 56 are fixedly installed in the middle of the outside of the conveyor belts 54. The staff turns on the servo motor 52 to work. Using the rotation of the output end of the servo motor 52, the rotating roller 53 can be driven to rotate clockwise, so that the conveyor belt 54 drives the round rod 55 and the poking teeth 56 to operate. At this time, the round rods 55 evenly distributed on the outside of the conveyor belt 54 can intercept the block sundries in the soil sample, and the crushed soil falls from the space between two adjacent round rods 55. Along with the continuous operation of the conveyor belt 54 driving the round rod 55, the intercepted block sundries can be transported out of the inside of the housing 1, so as to separate the soil and the block sundries.

[0028] There are two support frames 51, and the two support frames 51 are symmetrically installed along the round rod 55, and the support frames 51 are installed obliquely.

[0029] There are two conveyor belts 54, and the two conveyor belts 54 are symmetrically installed along the round rod 55. Using the two symmetrically arranged conveyor belts 54 for transmission makes the round rod 55 run smoothly. The poking teeth 56 are evenly distributed in the middle of the outside of the conveyor belt 54, and the poking teeth 56 are arranged staggered with the round rod 55.

[0030] The adjustment assembly 46 includes a guide rod 461, the top of which is fixedly installed at a position corresponding to the outer side of the fixed plate 42, a connecting sleeve 462 is slidably installed at the bottom of the guide rod 461, a spring 463 is fixedly installed between the upper end surface of the connecting sleeve 462 and the outer side of the guide rod 461, the guide rod 461 passes through the center of the spring 463, a plane baffle 464 is fixedly installed on the outer side of the connecting sleeve 462, and a force block 465 is fixedly installed at the corresponding position of the outer side of the plane baffle 464, and the position of the force block 465 corresponds to the position of the toggle tooth 56 Correspondingly, when the conveyor belt 54 drives the toggle tooth 56 to operate, the toggle tooth 56 at the top of the conveyor belt 54 moves to the upper right, and contacts the force block 465 with the toggle tooth 56, and continues to move with the toggle tooth 56. At this time, the force block 465 is subjected to an upward urging force, and then transmits the urging force to the plane baffle 464, and under the guidance of the guide rod 461 and the sliding connection of the connecting sleeve 462, the plane baffle 464 moves upward, and the spring 463 is compressed, thereby opening the rectangular notch 45, which can increase the leakage of the crushed soil sample; As the toggle tooth 56 separates from the force block 465, the jacking force on the force block 465 disappears, and under the elastic force provided by the spring 463, the plane baffle 464 moves downward to reset, and then the plane baffle 464 moves back and forth up and down to promote the leakage of crushed soil.

[0031] The plane baffle 464 is parallel to the fixed plate 42 to facilitate the movement of the fixed plate 42 , and the plane outside the fixed plate 42 is in contact with the plane outside the fixed plate 42 .

[0032] The second embodiment, as Figures 1 - 9 As shown, based on the first embodiment: The feeding assembly 2 includes a conical hopper 21, which is fixedly installed at the middle of the top of the shell 1 by screws, and the bottom end of the conical hopper 21 passes through the top of the shell 1 and extends into the interior thereof, and a guide plate 22 is fixedly installed at the edge of the bottom of the conical hopper 21, and the guide plate 22 is installed just above the fixed plate 42, and a swing plate 23 is hingedly connected at the bottom of the conical hopper 21 and on the side away from the guide plate 22, and the swing plate 23 is installed just above the moving plate 43, and piercing pieces 24 are fixedly installed at corresponding positions on the outside of the swing plate 23. The staff puts the soil sample into the conical hopper 21, and then feeds the soil sample. As the soil sample falls, and the guide plate 22 is installed at an angle, the soil sample will be guided by the guide plate 22, so that the soil sample can smoothly enter between the fixed plate 42 and the moving plate 43, so that the soil sample will not be scattered at will.

[0033] When the movable plate 43 is pushed to the upper right by the output end of the cylinder 41, the top of the movable plate 43 applies a driving force to the swing plate 23, so that the swing plate 23 can swing counterclockwise to adjust the angle, thereby blocking the bottom end of the conical hopper 21, thereby reducing the amount of soil-like raw materials leaking down. When the movable plate 43 is driven back and forth by the output end of the cylinder 41, the swing plate 23 can swing back and forth, thereby controlling the amount of soil-like raw materials leaking down.

[0034] The guide plate 22 and the swing plate 23 are both installed at an angle, and the puncture piece 24 is installed just below the leakage port at the bottom of the conical hopper 21. When the swing plate 23 is pushed by the top of the movable plate 43 to rotate and adjust the angle, the puncture piece 24 will rotate together with the swing plate 23, thereby puncturing the soil sample material in the conical hopper 21, so that the soil sample material is not easy to adhere together and is not easy to get blocked.

[0035] The third embodiment, as Figures 1 - 7 and Figure 10 As shown, based on the first embodiment: A secondary processing assembly 6 is installed inside the shell 1. The secondary processing assembly 6 is installed near the bottom of the shell 1. The secondary processing assembly 6 includes a support frame 61. The outer edge of the support frame 61 is fixedly installed with the inner wall of the shell 1. A screen 62 is fixedly installed in the middle of the top of the support frame 61. A zigzag frame 63 is fixedly installed on the side of the top of the support frame 61. A hook plate 64 is hinged on the top of the zigzag frame 63. The position of the hook plate 64 corresponds to the position of the toggle tooth 56. A diamond-shaped elastic frame 65 is fixedly installed between the outer side of the hook plate 64 and the inner wall of the shell 1. A percussion hammer 66 is fixedly installed at the bottom of the hook plate 64. After the block debris is separated from the crushed soil, the crushed soil falls onto the screen 62. At this time, the screen 62 filters out the granular stones in the crushed soil, while the crushed soil continues to leak down and is discharged from the discharge port 3. At the same time, the conveyor belt 54 is used to drive the toggle tooth 56 to operate. At this time, the toggle tooth 56 at the bottom of the conveyor belt 54 contacts the top of the hook plate 64, and the top of the hook plate 64 is pushed to the lower left, so that the hook plate 64 drives the knocking hammer 66 to rotate counterclockwise, and the diamond-shaped elastic frame 65 is compressed. As the toggle tooth 56 continues to move, the toggle tooth 56 is separated from the top of the hook plate 64. At this time, the driving force on the hook plate 64 disappears, and under the elastic force of the diamond-shaped elastic frame 65, the hook plate 64 drives the knocking hammer 66 to rotate clockwise to reset, so that the bottom end of the knocking hammer 66 knocks on the screen 62, causing the screen 62 to vibrate, thereby promoting the screening of the soil sample.

[0036] The hook plate 64 and the knock hammer 66 are both installed at an angle, and the knock hammer 66 is installed just above the screen 62 .

[0037] When in use, the staff first turns on the servo motor 52 to work, and the output end of the servo motor 52 rotates to drive the rotating roller 53 to rotate clockwise, so that the conveyor belt 54 drives the round rod 55 and the toggle gear 56 to operate, and then turns on the cylinder 41 to work, and the output end of the cylinder 41 extends and contracts to drive the moving plate 43 to reciprocate; At this time, the staff puts the soil sample into the conical hopper 21, and then loads the soil sample. As the soil sample falls, and the guide plate 22 is installed obliquely, the soil sample will be guided by the guide plate 22, so that the soil sample can smoothly enter between the fixed plate 42 and the movable plate 43, so that the soil sample will not be scattered at will.

[0038] When the output end of the cylinder 41 is used to push the moving plate 43 to move to the upper right, the top of the moving plate 43 applies a driving force to the swing plate 23, so that the swing plate 23 can swing counterclockwise to adjust the angle, so as to block the bottom end of the conical hopper 21, thereby reducing the amount of soil-like raw materials leaking down. When the moving plate 43 is driven to reciprocate by the output end of the cylinder 41, the swing plate 23 can swing back and forth, thereby controlling the amount of soil-like raw materials leaking down. When the movable plate 43 approaches the fixed plate 42, the soil sample falling between the movable plate 43 and the fixed plate 42 will be squeezed, so that the mud mass attached to the dry soil is squeezed, and the mud mass is broken in time. The round rods 55 evenly distributed on the outside of the conveyor belt 54 can intercept the block debris in the soil sample, and the broken soil falls from the space between two adjacent round rods 55. With the continuous operation of the round rods 55 driven by the conveyor belt 54, the intercepted block debris can be transported out of the interior of the housing 1, so that the soil and the block debris are separated. At the same time, when the conveyor belt 54 drives the toggle tooth 56 to operate, the toggle tooth 56 at the top of the conveyor belt 54 moves to the upper right, and contacts the force block 465 with the toggle tooth 56, and continues to move with the toggle tooth 56. At this time, the force block 465 is subjected to an upward urging force, and then transmits the urging force to the plane baffle 464, and under the guidance of the guide rod 461 and the sliding connection of the connecting sleeve 462, the plane baffle 464 moves upward, and the spring 463 is compressed, thereby opening the rectangular notch 45, which can increase the amount of soil sample leakage after crushing; As the toggle tooth 56 separates from the force block 465, the jacking force on the force block 465 disappears, and under the elastic force provided by the spring 463, the plane baffle 464 moves downward to reset, and then the plane baffle 464 moves up and down reciprocatingly, promoting the leakage of crushed soil; After the block debris is separated from the crushed soil, the crushed soil falls onto the screen 62. The screen 62 filters out the granular stones in the crushed soil, while the crushed soil continues to flow down and is discharged from the discharge port 3. The conveyor belt 54 is used to drive the toggle tooth 56 to operate. At this time, the toggle tooth 56 at the bottom of the conveyor belt 54 contacts the top of the hook plate 64, and the top of the hook plate 64 is pushed to the lower left, so that the hook plate 64 drives the knocking hammer 66 to rotate counterclockwise, and the diamond elastic frame 65 is compressed. As the toggle tooth 56 continues to move, the toggle tooth 56 is separated from the top of the hook plate 64. At this time, the driving force on the hook plate 64 disappears, and under the elastic force of the diamond elastic frame 65, the hook plate 64 drives the knocking hammer 66 to rotate clockwise to reset, so that the bottom end of the knocking hammer 66 knocks on the screen 62, causing the screen 62 to vibrate, thereby promoting the screening of the soil sample.
