Description

Technical Field

[0001] The present invention relates to the technical field of soil detection equipment, and specifically discloses a soil component detection device. Background Art

[0002] Soil detection refers to measuring various physical and chemical properties of soil by using appropriate measurement methods, such as iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, moisture, total arsenic, available boron, fluoride, chloride, mineral oil, and total salt content, etc., to achieve the monitoring of the current situation of soil quality and the monitoring of soil pollution accidents. Currently, when detecting soil, since the soil contains a certain amount of moisture, the detection equipment cannot accurately detect the exact content of various substances in the soil that has not been crushed and dried, and the practicability is poor.

[0003] To solve the above problems, a Chinese patent with the publication number CN221100216U discloses a soil screening device for soil detection, including a frame. A first motor is fixedly installed on the outer wall at the rear end of the frame, and the output end of the first motor is fixedly connected to a first rotating shaft, and the other end of the first rotating shaft is rotatably connected to the inner wall at the front end of the frame. When this device is in use, first, by starting the first motor, two crushing rollers are driven to initially crush the soil, and then it enters into the inner part of the arc-shaped sieve plate through the arranged guide inclined plate. Then, the second motor is started and the heating rod is powered on, so that while the stirring rod stirs the soil, the soil is heated and dried, thereby realizing the crushing and drying of the soil and improving the practicability of this device.

[0004] The above device has the following problems in the actual use process: when the crushing rollers crush the soil, due to the certain viscosity of the soil, part of the soil will adhere to the crushing rollers. If this part of the soil adhering to the crushing rollers is not cleaned in time, the amount of soil adhering to the crushing rollers will become more and more. And due to the large amount of soil adhesion, the crushing effect of the crushing rollers is reduced, the crushing efficiency of the crushing rollers for the soil is decreased, and it cannot meet the long-term crushing work of the soil, and the practicability is poor. Summary of the Invention

[0005] The present invention provides a soil component detection device to solve the problem that the existing detection device cannot clean the soil adhering to the crushing rollers when crushing the soil.

[0006] To achieve the above object, the present invention adopts the following technical solution: A soil component detection device, comprising a detection cylinder with an open top, a cleaning mechanism, and a detection mechanism disposed within the detection cylinder; the cleaning mechanism includes a hollow block, a feed hopper, crushing rollers symmetrically disposed on both sides of the hollow block along the width direction of the hollow block, cleaning components symmetrically disposed on both sides of the hollow block along the width direction of the hollow block, and a drive component for driving the two crushing rollers to rotate; the hollow block is respectively communicated with the detection cylinder and the feed hopper; the crushing rollers are rotatably connected to the hollow block; the cleaning components include a first screw rod, a first guide rod, a plurality of cleaning portions equidistantly disposed along the axial direction of the first screw rod, a placement groove formed on the inner wall of the hollow block, and a power portion for driving the first screw rod to rotate forward and reverse; the first screw rod is rotatably connected to the placement groove; the first guide rod is fixedly connected to the placement groove; the cleaning portion includes a nut seat, a hollow shaft, and a cleaning block; the nut seat is threadedly connected to the first screw rod, and the nut seat is slidably connected to the first guide rod; the hollow shaft is connected to the nut seat; the cleaning block is connected to the hollow shaft, and the cleaning block is in contact with the crushing roller.

[0007] The principle and advantages of this solution are as follows:

[0008] 1. The soil to be detected is introduced into the hollow block along the feed hopper, and then the soil is crushed by the crushing rollers, so that various substances contained in the soil can be crushed and separated, thereby enhancing the detection effect of the detection cylinder on the soil and improving the detection efficiency of the detection cylinder on the soil.

[0009] During the rotation of the crushing rollers, since the cleaning blocks are in contact with the crushing rollers, the cleaning blocks can clean the soil adhered to the crushing rollers, so that the soil can no longer adhere to the crushing rollers and finally fall into the detection cylinder. Through the above movements, on the one hand, the recycling rate of the soil is improved, so that the soil can be completely detected in the detection cylinder, improving the accuracy of the soil detection; on the other hand, the influence of the soil on the crushing rollers is reduced, so that the crushing rollers are not affected by soil adhesion, enhancing the crushing effect of the crushing rollers and improving the crushing efficiency of the crushing rollers.

[0010] 2. During the cleaning of the crushing rollers by the cleaning blocks, the nut seats can drive the cleaning blocks to make reciprocating movements along the axial direction of the crushing rollers. During the movement of the cleaning blocks, the cleaning blocks have a certain acting force, so that the cleaning blocks can clean the soil adhered to the crushing rollers more fully and completely, further reducing the amount of soil adhered to the crushing rollers and improving the cleaning quality of the cleaning blocks on the crushing rollers.

[0011] In summary, through the rotation of the crushing rollers and the transverse reciprocating movement of the cleaning blocks, the soil adhered to any position on the crushing rollers can be cleaned, ensuring that the crushing rollers can maintain a stable working state, that is, improving the detection efficiency of the soil.

[0012] Further, it further includes a first rack fixedly connected in the placement groove; the hollow shaft is rotatably connected to the nut seat; a first gear is fixedly connected to the hollow shaft, and the first gear meshes with the first rack.

[0013] Through the mutual cooperation of the first gear and the first rack, the cleaning block can be rotated, that is, while the cleaning block reciprocates along the axial direction of the crushing roller, the cleaning block can also rotate. During the rotation of the cleaning block, the cleaning range of the cleaning block can be expanded, and the acting force of the cleaning block can be enhanced. Therefore, the cleaning block can clean the soil adhered to the crushing roller more comprehensively and thoroughly, thereby further reducing the amount of soil adhered to the crushing roller, ensuring that the soil does not interfere with the crushing work of the crushing roller, that is, the crushing roller can always maintain an efficient working state.

[0014] Further, it further includes a plurality of arc-shaped concave blocks arranged in the placement groove; two adjacent arc-shaped concave blocks are fixedly connected to form a side block, and the side block is fixedly connected to the placement groove; it further includes a linkage unit arranged in the hollow shaft; the linkage unit includes a linkage block, a spherical wedge block, and a first spring; the linkage block is slidably connected to the hollow shaft; the spherical wedge block is fixedly connected to the linkage block, and the spherical wedge block abuts against the arc-shaped concave block; both ends of the first spring are respectively connected to the linkage block and the inner wall of the hollow shaft; the cleaning block is an elastic block; the cleaning block is fixedly connected to the linkage block.

[0015] Under the mutual action of the spherical wedge block, the arc-shaped concave block, and the first spring, the linkage block can continuously squeeze the cleaning block, that is, the cleaning block deforms under the reaction force of the crushing roller. During the deformation of the cleaning block, the fitting degree with the crushing roller can be improved, and the friction force between the cleaning block and the crushing roller can be increased. That is, the acting force of the cleaning block on soil cleaning is further enhanced, so that the soil adhered to the crushing roller can be easily scraped off under a stronger acting force, and the amount of soil adhered to the crushing roller is further reduced. Moreover, during the deformation of the cleaning block, the contact range between the cleaning block and the crushing roller can be expanded, so that the cleaning block can clean the crushing roller more efficiently, shortening the cleaning time of the cleaning block for the crushing roller.

[0016] In summary, through the combined action of the lateral movement of the cleaning block, the rotation of the cleaning block, and the deformation of the cleaning block, the cleaning effect of the cleaning block on the crushing roller is comprehensively enhanced, ensuring that the soil adhered to the crushing roller can be completely cleaned under the action of the cleaning block, thereby improving the cleaning efficiency of the crushing roller and ensuring the cleaning quality of the crushing roller.

[0017] Further, a disc is fixedly connected to the outer wall of the hollow shaft; it further includes sweeping units symmetrically arranged on both sides of the hollow shaft along the axial direction of the hollow shaft; the sweeping unit includes a movable block, a plurality of flexible blocks, a sliding hole opened on the disc, and a moving member for driving the movable block to reciprocate along the length direction of the sliding hole; the movable block is slidably connected to the sliding hole; a plurality of flexible blocks are all fixedly connected to the movable block, and the flexible blocks are in contact with the crushing roller.

[0018] During the cleaning of the soil adhering to the crushing roller by the cleaning block, the flexible block is driven by the movable block to reciprocate along the length direction of the sliding hole. During the movement of the flexible block, on the one hand, the flexible block can weaken the acting force of the soil adhering to the crushing roller, making the soil loose, and then promoting the soil to no longer adhere to the crushing roller under the action of the cleaning block, enhancing the cleaning effect of the cleaning block on the soil; on the other hand, the flexible block can sweep away the soil debris remaining on the crushing roller, thus reducing the amount of soil debris remaining on the crushing roller, that is, improving the cleanliness of the surface of the crushing roller, weakening the influence of the soil debris on the crushing roller, and comprehensively improving the cleaning effect on the crushing roller.

[0019] Furthermore, it also includes extrusion units symmetrically arranged on both sides of the hollow shaft along the axial direction of the hollow shaft; the extrusion unit includes side blocks, moving blocks, and power components for driving the moving blocks to reciprocate along the length direction of the side blocks; the side blocks are fixedly connected to the movable blocks; the moving blocks are slidably connected to the side blocks, and the moving blocks are in contact with the cleaning blocks.

[0020] During the cleaning of the crushing roller by the cleaning block, the moving blocks reciprocate along the length direction of the side blocks, so that the two moving blocks can squeeze the joint surface between the cleaning block and the crushing roller, making the acting force of the cleaning block on the surface of the crushing roller more concentrated, that is, further enhancing the acting force of the cleaning block, so that the cleaning block can clean the soil adhering to the crushing roller more efficiently.

[0021] Furthermore, it also includes impact components symmetrically arranged on both sides of the moving blocks along the width direction of the moving blocks; the impact components include a number of impact blocks; the impact blocks are fixedly connected to the moving blocks, and the crushing roller is located on the movement track of the impact blocks.

[0022] During the movement of the moving blocks, the impact blocks move synchronously. During the movement of the impact blocks, the impact blocks can impact the soil adhering to the crushing roller, making the soil loose, weakening the adhesion force of the soil adhering to the crushing roller, and promoting the soil adhering to the crushing roller to be completely cleaned under the combined action of the cleaning block and the flexible block, further accelerating the cleaning efficiency of the soil and shortening the cleaning time of the soil.

[0023] Furthermore, it also includes stirring units symmetrically arranged on both sides of the hollow shaft along the axial direction of the hollow shaft; the stirring unit includes a stirring shaft, a number of stirring components equidistantly arranged along the circumferential direction of the stirring shaft, and a driving component for driving the stirring shaft to rotate; the stirring shaft is rotatably connected to the disc; the stirring components include stirring blocks, and a number of conical blocks equidistantly arranged along the length direction of the stirring blocks; the stirring blocks are fixedly connected to the stirring shaft; the conical blocks are fixedly connected to the stirring blocks; the flexible block is located on the movement track of the stirring blocks.

[0024] During the rotation of the stirring block, the conical block moves synchronously. During the movement of the conical block, the conical block has a certain force, which can stir and break up the soil adhering to the crushing roller, realize the pretreatment of the soil adhering to the crushing roller, reduce the amount of soil adhering to the crushing roller, weaken the force, and prepare for the further treatment of the soil by the subsequent cleaning block, flexible block, and impact block.

[0025] Furthermore, it also includes auxiliary units symmetrically arranged on both sides of the hollow shaft along the axial direction of the hollow shaft; the auxiliary unit includes a telescopic rod, an auxiliary hole opened on the disc, and an auxiliary part used to drive the telescopic rod to reciprocate along the length direction of the auxiliary hole; the telescopic rod is slidably connected to the auxiliary hole, and the telescopic rod is in contact with the crushing roller.

[0026] When the cleaning block is cleaning the soil adhering to the crushing roller, the telescopic rod reciprocates along the length direction of the auxiliary hole, so that the telescopic rod has a certain moving effect on the soil adhering to the crushing roller, so that the soil adhering to the crushing roller can be moved under the action of the telescopic rod. That is, the amount of soil adhering to the crushing roller can be further reduced, the adhesion force will be further weakened, and the soil remaining on the crushing roller can be completely cleaned up under the action of the cleaning block.

[0027] Furthermore, the moving part includes a slider, a first cam, and a second spring; the slider is fixedly connected to the movable block; the first cam is fixedly connected to the stirring shaft, and the first cam abuts against the slider; and both ends of the second spring are respectively connected to the slider and the sliding hole.

[0028] During the rotation of the stirring shaft, the first cam rotates synchronously. During the rotation of the first cam, when the protrusion of the first cam abuts against the slider, the slider moves toward the position where the hollow block is located, and the second spring is compressed; when the protrusion of the first cam no longer abuts against the slider, the slider moves away from the position where the hollow block is located under the action of the second spring, and the slider is reset. During the movement of the slider, the movable block moves synchronously, so the movable block can reciprocate along the length direction of the slide hole.

[0029] Furthermore, the power part includes a rotating shaft, a second cam, a second gear, a second rack, a bar block, a side plate, a third spring, and a bar hole opened on the disc; the rotating shaft is rotatably connected to the disc; the second cam and the second gear are both fixedly connected to the rotating shaft; the second rack is fixedly connected to the slider, and the second rack is meshed with the second gear; the bar block is slidably connected to the bar hole, and the bar block is fixedly connected to the moving block; the side plate is fixedly connected to the bar block, and the second cam is abutted against the side plate; and the two ends of the third spring are respectively connected to the moving block and the side block.

[0030] During the movement of the slider, the second rack moves synchronously. During the movement of the second rack, the second rack meshes with the second gear, so that the second gear rotates. During the rotation of the second gear, the rotating shaft rotates synchronously.

[0031] During the rotation of the rotating shaft, the second cam rotates synchronously. During the rotation of the second cam, when the second cam abuts against the side plate, the side plate drives the moving block to move towards the position of the disc, and the third spring is compressed; when the convex part of the second cam no longer abuts against the side plate, the moving block resets under the action of the third spring. Therefore, the moving block can reciprocate along the length direction of the edge block. Description of the Drawings

[0054] Specific implementation process:

[0055] The soil to be detected is introduced into the hollow block 2 along the material guiding hopper 3, and the motor is started to drive the short shaft to rotate through the motor. During the rotation of the short shaft, the crushing roller 4 rotates synchronously. During the rotation of the crushing roller 4, the crushing roller 4 can crush the soil, so that various substances contained in the soil can be crushed and separated. Through the mutual cooperation of the detector and the air cylinder, the detection efficiency of the soil is improved.

[0056] During the rotation of the crushing roller 4, since the cleaning block 10 is in contact with the crushing roller 4, the cleaning block 10 can clean the soil adhered to the crushing roller 4, so that the soil can no longer adhere to the crushing roller 4 and finally fall into the detection cylinder 1.

[0057] During the cleaning of the crushing roller 4 by the cleaning block 10, the servo motor 12 is started, and the first screw 6 is driven to rotate by the output shaft of the servo motor 12. During the rotation of the first screw 6, the nut seat 8 can drive the cleaning block 10 to reciprocate along the axial direction of the crushing roller 4. During the movement of the cleaning block 10, the cleaning block 10 has a certain acting force, so that the cleaning block 10 can clean the soil adhering to the crushing roller 4 more fully and completely, further reducing the amount of soil adhering to the crushing roller 4 and improving the cleaning quality of the cleaning block 10 for the crushing roller 4.

[0058] In summary, through the rotation of the crushing roller 4 and the transverse reciprocating movement of the cleaning block 10, the soil adhering to any position on the crushing roller 4 can be cleaned, ensuring that the crushing roller 4 can maintain a stable working state, that is, improving the detection efficiency of the soil.

[0059] During the reciprocating movement of the nut seat 8, the hollow shaft 9 rotates through the engagement of the first gear 14 and the first rack 13. Therefore, while the hollow shaft 9 reciprocates along the length direction of the first guide rod 7, the hollow shaft 9 can also rotate. During the rotation of the hollow shaft 9, the cleaning block 10 can be rotated, that is, while the cleaning block 10 reciprocates along the axial direction of the crushing roller 4, the cleaning block 10 can also rotate. During the rotation of the cleaning block 10, the cleaning range of the cleaning block 10 can be expanded and the acting force of the cleaning block 10 can be enhanced. Therefore, the cleaning block 10 can clean the soil adhering to the crushing roller 4 more comprehensively and thoroughly, further reducing the amount of soil adhering to the crushing roller 4 and ensuring that the soil does not interfere with the crushing work of the crushing roller 4, that is, the crushing roller 4 can always maintain an efficient working state.

[0060] During the reciprocating movement of the hollow shaft 9 along the length direction of the first guide rod 7, under the interaction of the spherical wedge 17, the arc-shaped concave block 15, and the first spring, the linkage block 16 can continuously squeeze the cleaning block 10, that is, the cleaning block 10 deforms under the reaction of the crushing roller 4. During the deformation of the cleaning block 10, the fitting degree with the crushing roller 4 can be improved and the friction force between the cleaning block 10 and the crushing roller 4 can be increased. That is, the acting force of the cleaning block 10 for soil cleaning is further enhanced, so that the soil adhering to the crushing roller 4 can be easily scraped off under a stronger acting force, further reducing the amount of soil adhering to the crushing roller 4. Moreover, during the deformation of the cleaning block 10, the contact range between the cleaning block 10 and the crushing roller 4 can be expanded, so that the cleaning block 10 can clean the crushing roller 4 more efficiently and shorten the cleaning time of the cleaning block 10 for the crushing roller 4.

[0061] In summary, through the combined actions of the lateral movement, rotation, and deformation of the cleaning block 10, the cleaning effect of the cleaning block 10 on the crushing roller 4 is comprehensively enhanced, ensuring that the soil adhering to the crushing roller 4 can be completely cleaned under the action of the cleaning block 10, thereby improving the cleaning efficiency of the crushing roller 4 and ensuring the cleaning quality of the crushing roller 4.

[0062] During the cleaning of the soil adhering to the crushing roller 4 by the cleaning block 10, the stirring shaft 25 can rotate through the meshing of the fourth gear 42 and the annular rack 41. During the rotation of the stirring shaft 25 and the rotation of the stirring block 26, the conical block 27 moves synchronously. During the movement of the conical block 27, the conical block 27 has a certain acting force, and the conical block 27 can stir and disperse the soil adhering to the crushing roller 4, realizing the pretreatment of the soil adhering to the crushing roller 4, reducing the amount of soil adhering to the crushing roller 4 and weakening the acting force, and preparing for the further treatment of the soil by the subsequent cleaning block 10, flexible block 20, and impact block 24.

[0063] During the rotation of the stirring shaft 25, the first cam 31 rotates synchronously. During the rotation of the first cam 31, when the convex part of the first cam 31 abuts against the slider 30, the slider 30 moves towards the position where the hollow block 2 is located, and the second spring 32 is compressed; when the convex part of the first cam 31 no longer abuts against the slider 30, the slider 30 moves away from the position where the hollow block 2 is located under the action of the second spring 32, and the slider 30 resets. During the movement of the slider 30, the movable block 19 moves synchronously, so the movable block 19 can make a reciprocating movement along the length direction of the sliding hole 21.

[0064] During the movement of the movable block 19, the flexible block 20 moves synchronously. During the movement of the flexible block 20, on the one hand, the flexible block 20 can weaken the acting force of the soil adhering to the crushing roller 4, making the soil loose, and then promoting the soil to no longer adhere to the crushing roller 4 under the action of the cleaning block 10, enhancing the cleaning effect of the cleaning block 10 on the soil; on the other hand, the flexible block 20 can sweep away the soil debris remaining on the crushing roller 4, thereby reducing the amount of soil debris remaining on the crushing roller 4, that is, improving the cleanliness of the surface of the crushing roller 4, weakening the influence of the soil debris on the crushing roller 4, and comprehensively improving the cleaning effect on the crushing roller 4.

[0065] While the cleaning block 10 is cleaning the crushing roller 4, the side block 22 moves synchronously with the movable block 19. During the movement of the side block 22, the second screw is meshed with the second gear 35 through the second rack 36, so that the second screw can rotate. During the rotation of the second screw, the second cam 34 rotates synchronously. During the rotation of the second cam 34, when the second cam 34 abuts against the side plate 38, the side plate 38 drives the moving block 23 to move toward the position of the disc 18, and the third spring 39 is compressed; when the raised portion of the second cam 34 no longer abuts against the side plate 38, the moving block 23 is reset under the action of the third spring 39. Therefore, the moving block 23 can reciprocate along the length direction of the side block 22.

[0066] By reciprocating the moving block 23 along the length direction of the side block 22, the two moving blocks 23 can squeeze the fitting surface between the cleaning block 10 and the crushing roller 4, so that the surface force of the cleaning block 10 on the crushing roller 4 is more concentrated, that is, the force of the cleaning block 10 is further enhanced, so that the cleaning block 10 can clean the soil adhering to the crushing roller 4 more efficiently.

[0067] During the movement of the moving block 23, the impact block 24 moves synchronously. During the movement of the impact block 24, the impact block 24 can impact the soil adhering to the crushing roller 4, thereby loosening the soil, weakening the adhesion of the soil to the crushing roller 4, and promoting the soil adhering to the crushing roller 4 to be completely cleaned up under the joint action of the cleaning block 10 and the flexible block 20, further accelerating the cleaning efficiency of the soil and shortening the cleaning time of the soil.

[0068] During the cleaning block 10 cleaning the soil adhered to the crushing roller 4, the auxiliary block 44 can drive the telescopic rod 28 to make vertical reciprocating motion under the rotation of the second screw. The telescopic rod 28 reciprocates along the length direction of the auxiliary hole 29, so that the telescopic rod 28 has a certain shaking effect on the soil adhered to the crushing roller 4, so that the soil adhered to the crushing roller 4 can be shaken under the action of the telescopic rod 28. That is, the amount of soil adhered to the crushing roller 4 can be further reduced, the adhesion force will be further weakened, and the soil remaining on the crushing roller 4 can be completely cleaned under the action of the cleaning block 10.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention.
