Description

Technical Field

[0001] The invention relates to the technical field of soil sample processing, and in particular to a sample grinding device for soil detection. Background Art

[0002] Soil sample preparation refers to the process of mixing, drying, grinding and sieving soil samples after they are collected from the field. After collecting the soil, it is necessary to analyze the chemical elements and test various indicators. The collected soil samples often have large particles and cannot be directly analyzed and tested. Later, the experimenters need to grind, screen and other operations on them before they can be placed in the testing instrument for detection. When grinding, the experimenters usually put the soil in a mortar and then crush and grind the soil. However, when grinding the soil, the moisture of the sampled soil can easily increase the difficulty of soil grinding, causing the soil to adhere to the inside of the equipment due to moisture during the grinding process, reducing the discharge of soil during equipment grinding, and the soil is easily mixed with debris such as stones and branches during soil sampling, resulting in insufficient grinding of the soil during the grinding process. When the debris moves with the soil inside the equipment, it is easy to affect the accuracy of soil detection after grinding. When the debris moves inside the equipment, it is easy to accumulate, causing the equipment to be blocked and affect the soil grinding work.

[0003] In summary, when grinding soil, if the soil sampled is moist, it is easy to increase the difficulty of soil grinding, causing the soil to adhere to the inside of the equipment due to moisture during the grinding process. In addition, when sampling soil, it is easy for debris such as stones and branches to be mixed in.

[0015] The present invention provides a sample grinding device for soil testing, which has the following beneficial effects: The sample grinding device for soil detection is provided with a stirring plate, a boosting plate, and a grinding roller. The heater is operated to transport heat to a position inside the grinding cylinder close to a pretreatment component and a screening component, so that the heat circulates inside the grinding cylinder to dry the soil. The stirring plate is rotated to break up the added soil, so as to prevent the soil from agglomerating inside the grinding cylinder, and ensure that the soil is fully heated and dried when the stirring plate stirs the soil. The transmission shaft drives the grinding roller to move when rotating, so that the soil can be screened by the screening component after being ground, and the quality of soil grinding is ensured. The boosting plate is driven by the stirring plate to move along the pretreatment component, so as to ensure that the pretreatment component separates the broken soil from the sundries.

[0016] The sample grinding device for soil detection is located below the pretreatment component through the screening sleeve, which is convenient for the screening sleeve to support the screening plate on the grinding cylinder so that the screening plate can screen the ground soil, ensuring that the screening sleeve can protect the position of the screening plate along the soil, and the side support plates are evenly distributed inside the screening sleeve so that the side support plates can share the pressure on the support ring, thereby increasing the bearing capacity of the support ring itself and preventing the side support plates from sliding down on the screening plate.

[0017] The sample grinding device for soil detection is driven to rotate by the transmission shaft through the linkage block, so that the cleaning ring cleans the screening plate, thereby avoiding clogging of the screening plate when the ground soil falls. The rotation of the linkage block is limited by the transmission shaft and the screening plate, and the support ring contacts the cleaning ring on the side support plate, so that the support ring can support the cleaning ring, which is convenient for keeping the cleaning ring fully in contact with the screening plate during rotation, so that the support ring can reinforce the cleaning ring.

[0018] The sample grinding device for soil detection has an inner connection block supported by a side support plate to contact the linkage block, thereby increasing the contact area of ​​the linkage block when rotating, ensuring that the transmission shaft is vertically installed inside the grinding cylinder, and the side connection plate supports the middle solid ring inside the screening sleeve, so that the middle solid ring is horizontally installed below the inner connection block, so that the side connection plate and the side support plate cooperate to reinforce the screening sleeve, prevent the screening sleeve from sliding down due to excessive pressure on the screening plate, and buffer the soil when it falls and contacts the side connection plate.

[0019] The sample grinding device for soil detection generates vibrations when the vibrator is working on the vibrator protection shell, so that the vibrator protection shell collides with the contacting parts during the lifting process. The middle solid ring can fix the telescopic plate, so that the telescopic plate is reinforced by the middle solid ring to prevent the telescopic plate from sliding off from the inside of the middle solid ring during the lifting process, so that the vibrator protection shell is located below the inner block, so that the telescopic plate and the vibrator protection shell limit the distance between the middle solid ring and the inner block.

[0020] The sample grinding device for soil detection fixes the filter plate through the receiving sleeve and the inside of the grinding cylinder, so that the soil stirred by the stirring plate and the boosting plate is filtered on the filter plate, and the soil is prevented from being excessively accumulated on the filter plate and affecting the addition and drying of the soil. The limiting plate supports the filter plate and the mounting ring on the receiving sleeve, so that the limiting plate presses the filter plate tightly, thereby increasing the bearing capacity of the filter plate and preventing the filter plate from tilting when filtering the soil, resulting in the direct fall of unfiltered soil.

[0021] The sample grinding device for soil detection rotates on the mounting ring through the knocking plate driven by the soil falling from the filter disc, so that the filter disc is cleaned by the vibration force generated by the knocking of the knocking plate, and the knocking plate cooperates with the boosting plate to accelerate the falling of the soil on the filter disc. The elastic plate connects the knocking plate and the mounting ring, so that the elastic plate can be extended and retracted as the knocking plate rotates, so that when the knocking plate loses the thrust of the soil, the elastic plate can drive the knocking plate to reset, thereby ensuring the knocking effect of the knocking plate on the filter disc.

[0022] The sample grinding device for soil detection fixes the material guide cylinder on the grinding cylinder by means of a clamping block, thereby increasing the firmness of the screening sleeve itself and preventing the material guide cylinder from sliding down and affecting the falling of soil; the blocking plate and the inner ring frame cooperate with each other to reinforce the material guide cylinder, thereby increasing the bearing capacity of the material guide cylinder itself and preventing the falling of soil guided by the material guide cylinder from being affected; the inner ring frame is located below the blocking plate, so that the inner ring frame limits the installation position of the blocking plate.

[0023] The sample grinding device for soil detection is vertically installed on the inner ring frame through an external column, so that the external column is extended to contact the lifting vibrator protection shell, so that the external column limits the descending distance of the vibrator protection shell, prevents the telescopic plate from falling on the middle fixed ring and causing the vibrator protection shell to loosen, and when the movable frame rotates to contact the inner ring frame, the movable frame can knock the inner ring frame, thereby increasing the vibration force on the inner ring frame, thereby ensuring the cleaning effect of the inner ring frame.

[0024] The sample grinding device for soil detection has a bracket located above the movable bracket, so that the bracket is connected to the arc plate to fix the external column, which is convenient for sharing the pressure on the external column and preventing the external column from tilting on the internal ring bracket. The rotating bracket is rotated on the bracket by the push of the fallen soil, so that the rotation of the rotating bracket can play a role in promoting the falling of the soil. The rotating bracket can generate wind force when rotating, and the wind force is used to blow the soil dropped at other positions, thereby ensuring the integrity of the bracket itself.

The guide cylinder 62 is fixed on the grinding cylinder 1 by the clamping block 61, so that the guide cylinder 62 supports the screening sleeve 31 inside the grinding cylinder 1, thereby increasing the firmness of the screening sleeve 31 itself. Two clamping blocks 61 are provided to fix the guide cylinder 62 at different positions, thereby increasing the bearing force generated by the guide cylinder 62 inside the grinding cylinder 1, preventing the guide cylinder 62 from sliding down and affecting the falling of the soil. The inner surface of 62 is fixedly connected with a blocking plate 65, which is evenly distributed inside the guide barrel 62, so that the activity space between the two blocking plates 65 can guide the flow of soil, so that the soil can slide along the activity space between the two blocking plates 65 when it contacts the inner wall of the guide barrel 62, and the blocking plate 65 cooperates with the inner ring frame 64 to reinforce the guide barrel 62, thereby increasing the bearing capacity of the guide barrel 62 itself and preventing the guide barrel 62 from guiding the soil to fall and being affected. The inner ring frame 64 is located below the blocking plate 65, so that the inner ring frame 64 limits the installation position of the blocking plate 65; The inner ring frame 64 is fixedly connected to the position of the guide barrel 62 near the blocking plate 65. The inner surface of the inner ring frame 64 is fixedly connected with an external column 66. The external column 66 is vertically installed on the inner ring frame 64, so that the external column 66 extends out to contact the lifting vibrator protection shell 39, so that the external column 66 limits the descending distance of the vibrator protection shell 39, so that the external column 66 protects the vibrator protection shell 39 to prevent the telescopic plate 311 from falling on the middle fixed ring 310 and causing the vibrator protection shell 39 to loosen, and the external column 66 is hit by the vibrator protection shell 39 to transmit the vibration force, so that the inner ring frame 64 is affected by the external column 66. The vibration force cleans the adhered soil, and the outer surface of the external column 66 is slidably connected to the movable frame 63, which is driven by the movable frame 63 on the external column 66 to rotate slightly, so that the rotation of the movable frame 63 can guide the fallen soil, and the movable frame 63 protects the position where the external column 66 is connected to the internal ring frame 64, and when the movable frame 63 rotates to contact the internal ring frame 64, the movable frame 63 can knock the internal ring frame 64, thereby increasing the vibration force on the internal ring frame 64, and then ensuring the cleaning effect of the internal ring frame 64, the movable frame 63 can increase the contact area of ​​the external column 66, so that the movable frame 63 and the internal ring frame 64 cooperate to separate the falling space of the soil.

[0037] The side of the clamping block 61 away from the material guide cylinder 62 is fixedly connected to the grinding cylinder 1 , and the top end of the external connection column 66 extends to the outside of the internal connection ring frame 64 .

[0038] Among them, the position of the external column 66 near the movable frame 63 is fixedly connected with a bracket 67, and the bracket 67 is located above the movable frame 63, so that the bracket 67 is connected to the arc plate 610 to fix the external column 66, which is convenient for sharing the pressure on the external column 66 and preventing the external column 66 from tilting on the inner ring frame 64. The connection between the bracket 67 and the arc plate 610 can separate the space for the soil to fall inside the guide barrel 62, so that the soil that does not contact the inner wall of the guide barrel 62 can fall directly, so as to guide the falling of the soil by using the space separated by the bracket 67 and the arc plate 610. The position of the bracket 67 away from the external column 66 is fixedly connected with the arc plate 610, the side of the arc plate 610 away from the bracket 67 is fixedly connected to the guide cylinder 62, and the outer surface of the bracket 67 is rotatably connected to the rotating frame 68, and the rotating frame 68 is pushed by the falling soil on the bracket 67 to rotate, so that the rotation of the rotating frame 68 can play a role in promoting the falling of the soil. When the rotating frame 68 rotates, it can generate wind force, and use the wind force to blow the soil fallen at other positions, so as to accelerate the falling of the soil. The rotating frame 68 can protect the bracket 67, thereby increasing the bearing capacity of the bracket 67 near the arc plate 610, preventing the bracket 67 from being damaged by pressure, and thus ensuring the integrity of the bracket 67 itself; The assembly plate 69 is fixedly connected to the position of the external column 66 near the bracket 67, and the bottom of the assembly plate 69 is fixedly connected to the outrigger rod 611. The assembly plate 69 is subjected to the pressure of the falling soil on the external column 66 to push the outrigger rod 611 to descend, so that the outrigger rod 611 pushes when it contacts the movable frame 63, so that the outrigger rod 611 descends and drives the movable frame 63 to rotate. When the assembly plate 69 loses pressure, it drives the outrigger rod 611 to rise, so that the outrigger rod 611 moves along the bracket 67, ensuring that the outrigger rod 611 moves in the vertical direction when moving, so that the lifting and lowering of the outrigger rod 611 can limit the assembly plate 69, and the assembly plate 69 can move repeatedly when subjected to the pressure of the soil, so that the assembly plate 69 drives the outrigger rod 611 to rise and fall repeatedly and pushes when it contacts the movable frame 63, and the outer surface of the outrigger rod 611 is slidably connected to the bracket 67.

[0039] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using a sample grinding device for soil detection, step 1: adding a soil sample through the feed pipe of the grinding cylinder 1, the sample falls onto the filter disc 42 inside the grinding cylinder 1, the transmission shaft 10 is driven by the motor to rotate, so that the transmission shaft 10 rotates to drive the stirring plate 9 to rotate, so that the stirring plate 9 stirs the added soil, and as the stirring plate 9 rotates, the booster plate 8 is driven to move along the filter disc 42, so that the stirring plate 9 pushes the soil to move on the filter disc 42, and the heater 5 works to transport hot air into the grinding cylinder 1, so that the hot air circulates inside the grinding cylinder 1 to dry the soil at the filter disc 42 and the screening disc 32; Step 2: Use the filter disc 42 to receive the soil inside the receiving sleeve 41, so that the soil filtered by the filter disc 42 falls into the screening sleeve 31, and the limiting plate 43 supports the mounting ring 45 inside the receiving sleeve 41, so that the knocking plate 44 is driven by the soil dropped from the filter disc 42 to rotate on the mounting ring 45, and when the knocking plate 44 rotates to contact the filter disc 42, the knocking plate 44 knocks from the bottom of the filter disc 42, and the knocking plate 44 pulls the elastic plate 46 when rotating, so that the elastic plate 46 expands and contracts to drive the knocking plate 44 to reset; Step 3: The transmission shaft 10 rotates to drive the grinding roller 7 to move on the screening plate 32, so that the grinding roller 7 moves to grind the soil on the screening plate 32, and the heat delivered by the heater 5 during the soil grinding dries the ground soil again. As the ground soil falls below the screening plate 32, the soil leaves the inside of the screening sleeve 31, and the linkage block 33 rotates with the transmission shaft 10, so that the linkage block 33 rotates to drive the cleaning ring 35 to move along the bottom of the screening plate 32, so that the cleaning ring 35 cleans the ground screening plate 32, and the side support plate 34 supports the support ring 36 inside the screening sleeve 31, so that the support ring 36 supports the cleaning ring 35; Step 4: Use the clamping block 61 to support the guide barrel 62 inside the guide barrel 62, so that the guide barrel 62 guides the falling of the ground soil. When the soil moves along the inner wall of the guide barrel 62, it is restricted by the two blocking plates 65, so that the soil inside the guide barrel 62 is discharged to the inside of the collection box 2 for collection. The rotating frame 68 on the bracket 67 is pushed by the falling soil to rotate, so that the rotation of the rotating frame 68 can drive the circulation of the gas inside the grinding barrel 1. The arc plate 610 supports the bracket 67 inside the guide barrel 62, so that the bracket 67 is installed horizontally on the arc plate 610 and the external column 66; Step 5: Use the inner ring frame 64 to support the outer column 66 below the blocking plate 65, so that the outer column 66 is installed vertically. When the soil enters the guide tube 62 and contacts the assembly plate 69, the position of the assembly plate 69 close to the outrigger 611 falls due to the pressure of the soil. The assembly plate 69 falls and pushes the outrigger 611, so that the outrigger 611 slides up and down on the bracket 67 and contacts the movable frame 63. The movable frame 63 rotates slightly on the outer column 66 due to the thrust of the outrigger 611. When the assembly plate 69 loses the pressure of the soil, it resets, so that the assembly plate 69 drives the outrigger 611 to rise. Step six: The inner block 38 is supported by the side support plate 34 so that the inner block 38 contacts the linkage block 33, and the side plate 37 supports the middle solid ring 310 inside the screening sleeve 31 so that the middle solid ring 310 is kept horizontally installed below the inner block 38. As the vibrator inside the vibrator protective shell 39 vibrates when working, the vibrator protective shell 39 drives the telescopic plate 311 to rise and fall. The lifting of the vibrator protective shell 39 collides with the inner block 38 and the outer column 66, and the vibration force generated by the collision between the inner block 38 and the outer column 66 is transmitted. After the soil grinding is completed, the box door of the grinding cylinder 1 is opened, and the collection box 2 is pulled out of the grinding cylinder 1, and then the soil and dirt remaining on the filter plate 42 and the screening plate 32 are cleaned.
