Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, and in particular to a mine soil rapid sampler based on coal mining safety monitoring. Background Art

[0002] Coal mining in mining areas is a way of mining mineral resources, and its main purpose is to obtain coal as an energy material. Coal mining is generally divided into two methods: open-pit mining and underground mining. Open-pit mining mainly uses excavators, shovel loaders and other equipment to remove surface vegetation and soil to expose the coal layer, then uses blasting equipment to break the coal layer, and then uses trucks and other transportation tools to transport the coal out of the mining area. This method is suitable for mining areas with large coal reserves and simple geological conditions. Underground mining mainly uses various mechanized equipment and manpower to dig tunnels underground, gradually peel off the coal seam, and then crush and transport it. The underground mining method has a wide range of applications and can achieve a higher recovery rate, but the cost is high and it will cause certain damage to groundwater resources.

[0003] Coal mining safety monitoring is an important means to protect the lives and property of coal miners. During the coal mining process, monitoring of the underground environment and working surface, as well as sampling and analysis of coal seam soil and rock formations, are important means to evaluate coal quality and safety. Before exploring and mining coal mines, soil sampling is required. By analyzing the properties of the soil, we can understand the underground geological structure, lithology, etc., which provides an important basis for mine design and mining.

[0004] The structure of the existing soil samplers on the market is generally simple, usually directly connected by a sampling bucket, a rotating rod, a handle and a push rod. When sampling, hold the handle, aim the sampling bucket at the area to be sampled on the ground, and then repeatedly turn the handle with both hands to make the sampling bucket rotate and drill into the soil. After the soil is taken, the soil inside the sampling bucket is pushed out by pressing the push rod. Among them, since the top of the sampling bucket is sealed, it is not easy for the sampling bucket to drill into the soil when it is rotated to take soil, that is, the soil cannot quickly enter the sampling bucket, and after the sampling is completed, the soil is only brought out by the static friction between the soil and the inside of the sampling bucket. During the removal process, it is easy to cause the soil to fall; and the sampling bucket is drilled into the ground by the operator's repeated rotation of both hands, which is troublesome and inefficient, and cannot achieve rapid soil sampling. Summary of the invention

[0005] In view of the problems of poor sampling effect and slow sampling speed in the existing technical problems during soil sampling, a rapid soil sampler for mining areas based on coal mining safety monitoring is proposed.

[0006] The purpose is to keep the inside of the soil sampling pipe connected to the outside world through the connecting component during the soil sampling process, so that soil can enter quickly, and during the retrieval process, the soil sampling pipe can be sealed again to increase its internal adsorption force on the soil, thereby improving the stability and integrity of the soil sampling process.

The pressing assembly is used for pressing the soil taking tube downward when the soil taking tube rotates in one direction to take soil. The excavation assembly is used for pushing out the soil inside the soil taking tube after the soil taking tube has been completed. The one-way rotating assembly includes a one-way plate arranged in the top of the soil sampling pipe, a limiting groove opened in the middle of the one-way plate, an abutting groove opened in the limiting groove in an annular array, a rotating plate arranged in the limiting groove, a movable groove opened in the annular array on the side wall of the rotating plate, a fixed rod arranged on one side of the movable groove, an abutting block arranged on the fixed rod, a torsion spring arranged between the fixed rod and one side of the abutting block, and one side of the abutting block abuts against the abutting groove, a through hole opened in the annular array on the rotating plate for communication, a vertical groove opened in the annular array on the side wall of the rotating rod, and a pushing block limitedly slidably connected in the vertical groove, and one side of the pushing block is fixedly connected to the rotating plate.

[0008] Furthermore, the pressing assembly includes a reciprocating groove opened on the inner wall of the soil taking pipe, and a pressing rod annularly arranged at the bottom of the rotating pipe, and the pressing rod is located at the middle and lower part of the reciprocating groove in the vertical direction.

[0009] Furthermore, the excavation component includes a pushing rod arranged in the middle of the rotating tube, a stopper arranged on the top side wall of the pushing rod, a stopper groove opened inside the rotating tube, and the bottom of the stopper block abuts against the stopper groove, a pushing groove opened on one side of the stopper groove, a pushing plate arranged at the bottom of the pushing rod, and arc holes opened in a ring array at the edge of the pushing plate, and the pushing plate is located at the bottom of the reciprocating groove.

[0010] Furthermore, the length of the retaining groove is greater than the width of the retaining block.

[0011] Furthermore, the communication component includes a communication component arranged at the top of the inner cavity of the soil sampling pipe, and an elastic component arranged between the communication component and the soil sampling pipe; The connecting component includes a connecting hole in an annular array opened on the top of the soil sampling pipe, a circular plate connected to the side wall of the rotating tube for limited rotation, a movable groove in an annular array opened on the inner wall of the soil sampling pipe, a movable block arranged in the movable groove, and one end of the movable block is fixedly connected to the circular plate, the top of the circular plate is fixedly connected to the elastic component, a protective block in an annular array arranged on the top of the circular plate, and a connecting groove in an annular array opened between the two movable grooves.

In the process of taking out the soil, a negative pressure is formed inside the soil sampling tube. As the handle is continuously pulled upward, the stronger the negative pressure formed in the soil sampling tube, the stronger the adsorption effect on the soil, which can prevent the soil from falling, thereby achieving complete soil extraction, improving the soil extraction quality, and the stability and integrity during the soil sampling process.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] Example 1, reference Figure 1-Figure 11, which is the first embodiment of the present invention, provides a rapid soil sampler for a mining area based on coal mining safety monitoring, including a soil sampling tube 1, a rotating tube 11 rotatably connected to the top of the soil sampling tube 1, and handles fixedly connected to both sides of the rotating tube 11, and also includes a soil sampling unit installed inside the soil sampling tube 1; the soil sampling unit includes a connecting component installed on the top of the soil sampling tube 1, and a soil sampling component installed at the bottom of the connecting component; the soil sampling component is used to push the soil sampling tube 1 to rotate and extract soil during the downward pressing process of the rotating tube 11, and the connecting component is used to connect the soil sampling tube 1 with the outside air during the soil extraction process, so as to facilitate the entry of soil into the soil sampling tube 1; the soil sampling component includes a unidirectional rotating component 2 installed inside the soil sampling tube 1, a pressing component 3 installed at the bottom of the rotating tube 11, and an excavation component 4 installed in the rotating tube 11; the unidirectional rotating component 2 is used for the operator to reciprocate and drive the rotating tube 11 to rotate when extracting soil, thereby driving the soil sampling tube 1 to rotate continuously in one direction to extract soil, and the pressing component 3 is used to press the soil taking pipe 1 downward to take soil when the soil taking pipe 1 rotates in one direction, and the soil excavation component 4 is used to push the soil inside the soil taking pipe 1 after the soil taking pipe 1 completes the soil excavation; the one-way rotating component 2 includes a one-way plate 21 fixedly connected to the top of the soil taking pipe 1, a limiting groove 22 provided in the middle of the one-way plate 21, an abutting groove 23 provided in the limiting groove 22 in an annular array, a rotating plate 24 rotatably connected to the limiting groove 22, a movable groove provided on the side wall of the rotating plate 24 in an annular array, and a fixedly connected A fixed rod 25 on one side of the movable groove, an abutment block 26 rotatably connected to the fixed rod 25, a torsion spring abutting between the fixed rod 25 and one side of the abutment block 26, and one side of the abutment block 26 abuts against the abutment groove 23, a ring array of through holes 27 for communication are opened on the rotating plate 24, a ring array of vertical grooves 28 are opened on the side wall of the rotating rod, and a pushing block 29 is limitedly slidably connected in the vertical groove 28, and one side of the pushing block 29 is fixedly connected to the rotating plate 24.

[0022] Specifically, when sampling the soil in the mining area, the user holds the handle with both hands so that the bottom of the soil sampling tube 1 is aligned with the sampling area to be determined, and presses down the handle with both hands. The pressing component 3 presses down the soil sampling tube 1 so that the bottom of the soil sampling tube 1 can enter the soil, and after turning the handle counterclockwise and then clockwise, the one-way rotating component 2 can continuously push the soil sampling tube 1 to rotate in one direction, and the soil sampling tube 1 can be rotated to take soil without repeatedly rotating the rotating tube 11; when taking soil, the user presses down and rotates the handle so that the soil sampling tube 1 continues to enter the soil to take soil, and in the process of pressing down the handle, the soil sampling tube 1 can be connected to the outside air through the connecting component, so that The air pressure inside the soil sampling tube 1 is the same as that outside when taking soil, so that the soil can quickly enter the soil sampling tube 1 and realize rapid soil sampling; when the soil taking is completed, the unearthing component 4 will be pushed up to remind the soil taking personnel that the soil taking is completed and the soil sampling tube 1 can be taken out; at this time, the handle is pulled upward, and the connecting component 5 is also pulled upward synchronously, so that the inside of the soil sampling tube 1 is resealed, and the soil sampling tube 1 forms a negative pressure in the process of taking out the soil, and as the handle is continuously pulled upward, the negative pressure formed in the soil sampling tube 1 is stronger, and the adsorption effect on the soil is stronger, which can prevent the soil from falling, thereby realizing the complete removal of the soil and improving the soil taking efficiency.

[0023] When the handle is turned clockwise, the rotating tube 11 drives the pushing block 29 and the rotating plate 24 to rotate clockwise synchronously through the limiting action of the vertical groove 28, and the rotating plate 24 drives the abutment block 26 to rotate. The abutment block 26 abuts against the abutment groove 23 under the action of the torsion spring (the torsion spring is not drawn in the figure), and drives the one-way plate 21 to rotate clockwise synchronously. The one-way plate 21 synchronously drives the soil taking pipe 1 to rotate clockwise to take soil, thereby realizing unidirectional and continuous rotation of the soil taking pipe 1. There is no need for the operator to continuously and repeatedly turn the handle. The rotation operation is simple and efficient, which improves the soil taking efficiency of the soil taking pipe 1 when it is rotated.

[0024] Reference Figure 1-Figure 8 The pressing assembly 3 includes a reciprocating groove 31 formed on the inner wall of the soil taking pipe 1 and a pressing rod 32 annularly fixedly connected to the bottom of the rotating pipe 11, and the pressing rod 32 is located at the middle and lower part of the reciprocating groove 31 in the vertical direction.

[0025] Specifically, when taking soil, first press the handle downward to move the rotating tube 11 downward. At this time, the pushing block 29 moves in the vertical groove 28, and the lower pressure rod 32 moves downward in the reciprocating groove 31. When the lower pressure rod 32 is against the bottom of the reciprocating groove 31, the soil taking component is connected with the connecting component, so that the inside of the soil taking tube 1 is connected with the outside air; when the lower pressure rod 32 squeezes the reciprocating groove 31, the soil taking tube 1 is pressed downward, and then the handle is turned to make the lower pressure rod 32 rotate on the reciprocating groove 31, so that the soil taking tube 1 can be quickly rotated into the soil.

[0026] Reference Figure 1-Figure 9The excavation component 4 includes a pushing rod 41 rotatably connected to the middle of the rotating tube 11, a stopper 42 fixedly connected to the top side wall of the pushing rod 41, a stopper groove 43 provided inside the rotating tube 11, and the bottom of the stopper 42 abuts against the stopper groove 43, a pushing groove 44 provided on one side of the stopper groove 43, a pushing plate 45 fixedly connected to the bottom of the pushing rod 41, and an arc-shaped hole 46 provided in a ring array at the edge of the pushing plate 45, and the pushing plate 45 is located at the bottom of the reciprocating groove 31.

[0027] Specifically, when the soil enters the top of the soil taking pipe 1, the driving pipe is continued to be pressed down, and the soil will squeeze the pushing plate 45 upward, and the pushing plate 45 will simultaneously drive the pushing rod 41 to move upward, so that the stopper 42 moves upward in the blocking groove 43. At this time, the pushing rod 41 will be lifted up, and the operator can stop squeezing the handle to prevent the soil from entering the arc hole 46 and forming a blockage after the pushing plate 45 moves into place. The arc hole 46 is used to connect the interior of the soil taking pipe 1 to avoid affecting the connectivity of the air pressure inside the soil taking pipe 1; at this time, the handle is pulled upward, and the rotating pipe 11 drives the pressing rod 32 to move upward and against the top of the reciprocating groove 31, thereby bringing the soil taking pipe 1 out. At this time, the pushing plate 45 is driven by the rotating pipe 11 to move upward as a whole, and it is still in The bottom of the reciprocating groove 31 prevents soil from entering the reciprocating groove 31, thereby affecting the rotation of the pressing rod 32; when the soil taking tube 1 is taken out, the pushing rod 41 is rotated to make the stopper 42 rotate out of the stop groove 43. At this time, one hand holds the pushing rod 41, and the other hand presses the pushing rod 41, and the pushing plate 45 at the bottom pushes the soil out of the soil taking tube 1; and due to the opening of the arc hole 46, soil may still enter between it and the tube wall of the soil taking tube 1. At this time, the pushing rod 41 can be rotated so that the pushing plate 45 can repeatedly rotate in the soil taking tube 1 and move up and down, so as to push out the soil on the tube wall of the soil taking tube 1, thereby preventing the soil from adhering to the inner wall of the soil taking tube 1, improving the cleanliness of the inside of the soil taking tube 1, and enhancing the soil discharge effect.

[0028] Referring to FIG. 9 , the length of the stop groove 43 is greater than the width of the stop block 42 .

[0029] Specifically, such an arrangement facilitates that after soil excavation is completed, the push plate 45 can be pushed upward, thereby causing the push rod 41 to move upward, thereby achieving a reminder effect after soil excavation is completed.

[0030] Example 2, reference Figure 1-Figure 10, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the connecting component includes a connecting component 5 installed on the top of the inner cavity of the soil sampling pipe 1, and an elastic component 6 installed between the connecting component 5 and the soil sampling pipe 1; the connecting component 5 includes a connecting hole 51 in an annular array opened on the top of the soil sampling pipe 1, a circular plate 52 connected to the side wall of the rotating tube 11 for limited rotation, a moving groove 53 in an annular array opened on the inner wall of the soil sampling pipe 1, a moving block 54 sealingly and slidably connected in the moving groove 53, and one end of the moving block 54 is fixedly connected to the circular plate 52, the top of the circular plate 52 is fixedly connected to the elastic component 6, a protective block 55 fixedly connected to the top of the circular plate 52 in an annular array, and a connecting groove 56 in an annular array opened between the two moving grooves 53.

[0031] Specifically, in the initial state, the circular plate 52 is separated into two parts by the force of the spring 61, and the upper and lower parts are not connected, and the position above the connecting groove 56 in the soil taking pipe 1 is sealed and slidably connected with the side wall of the circular plate 52. When the handle is pressed down, the rotating tube 11 will drive the circular plate 52 to move down synchronously, and the circular plate 52 stretches the spring 61, so that the side wall of the circular plate 52 passes through the connecting groove 56, so that the bottom of the circular plate 52 is connected to the outside air through the connecting groove 56. At this time, the air pressure inside the soil taking pipe 1 is the same as the atmospheric pressure, so that the soil taking pipe 1 is pressed down. When the soil sampling is completed, the handle is no longer pressed down. At this time, under the reset action of the spring 61 and the limiting action of the movable groove 53, the circular plate 52 blocks the top of the connecting groove 56 again, so that a closed cavity is formed at the top of the soil sampling tube 1. When the rotating tube 11 is continuously pulled up, the circular plate 52 is continuously driven to move upward, so that a negative pressure is formed at the bottom of the circular plate 52, thereby adsorbing the soil entering the soil sampling tube 1, preventing the soil from falling, and improving the efficiency of soil sampling.

[0032] Reference Figure 1-Figure 10 The elastic component 6 includes a spring 61 sleeved on the rotating tube 11, a mounting groove 62 provided on the inner top wall of the soil taking tube 1, and the top of the spring 61 is fixedly connected to the mounting groove 62, and the bottom of the spring 61 is fixedly connected to the top of the circular plate 52.

[0033] Specifically, when the rotating tube 11 is pulled up, the spring 61 is compressed, and the protection block 55 is designed to protect the spring 61 and prevent the spring 61 from being crushed.

[0034] Reference Figure 1-Figure 10 When the elastic component 6 is in a non-stressed state, the circular plate 52 blocks the connecting groove 56 .

[0035] Specifically, in the initial state, the circular plate 52 blocks the communicating groove 56 under the pulling force of the spring 61, so that when the soil extraction and downward pressure are stopped, an automatic sealing effect can be achieved.

[0036] Reference Fig.11 The bottom of the soil-boring pipe 1 is serrated, and an annular array of side walls at the bottom of the soil-boring pipe 1 is provided with inclined soil-expanding pieces 7.

[0037] Specifically, the sawtooth design facilitates the soil taking pipe 1 to quickly enter the soil when rotating, and the expansion piece 7 is used to expand the diameter of the soil after rotation during the soil taking process, that is, to prevent the cylindrical soil drilling groove formed after rotating the soil from being too close to the inner wall of the soil taking pipe 1, thereby affecting the removal of the soil after the soil taking pipe 1, thereby facilitating the speed of soil removal. The rest of the structure is the same as that of Example 1.

[0038] In summary, the working principle of the present invention is as follows: when sampling the soil in the mining area, hold the handle with both hands so that the bottom of the soil sampling tube 1 is aligned with the sampling area to be determined, press the handle with both hands, and the pressing component 3 presses down the soil sampling tube 1 so that the bottom of the soil sampling tube 1 can enter the soil, and after turning the handle counterclockwise and then clockwise, the one-way rotating component 2 can continuously push the soil sampling tube 1 to rotate in one direction, and the soil sampling tube 1 can be rotated to take soil without repeatedly rotating the rotating tube 11; when taking soil, press down and rotate the handle so that the soil sampling tube 1 continues to enter the soil for taking soil, and in the process of pressing down the handle, the soil sampling tube 1 can be connected to the outside through the connecting component. The soil taking tube 1 is connected with the outside air so that the air pressure inside it is the same as that outside when taking soil, so that the soil can quickly enter the soil taking tube 1 and realize rapid soil sampling; when the soil taking is completed, the unearthing component 4 will be pushed up to remind the soil taking personnel that the soil taking is completed and the soil taking tube 1 can be taken out; at this time, the handle is pulled upward, and the connecting component 5 is also pulled upward synchronously, so that the inside of the soil taking tube 1 is resealed, and negative pressure is formed inside the soil taking tube 1 in the process of taking out the soil, and as the handle is continuously pulled upward, the stronger the negative pressure formed in the soil taking tube 1, the stronger the adsorption effect on the soil, which can prevent the soil from falling, thereby realizing the complete removal of the soil and improving the soil taking efficiency.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
