Description

Technical Field

[0001] The utility model relates to the technical field of coal reserve surveying and mapping, and particularly to a coal reserve surveying and mapping device. Background Art

[0002] The coal reserve surveying and mapping device is an important equipment for reserve assessment and geological exploration of coal mines. Its main purpose is to accurately calculate the coal reserves of coal mines through geological exploration, sampling, measurement and data analysis, and support the development and management of mines.

[0003] After retrieval, the Chinese patent "a coal mine surveying and positioning instrument" with the authorization announcement number "CN221037418U" realizes the release and limit of the soil box through a drill bit, a collection box, a soil box, a rotating motor, a fixed shaft and a fixing wire. When the drill bit moves upward, due to the resistance, the soil in the soil layer will enter the interior of the soil box to complete the collection. After the collection is completed, the rotating motor is used to rewind the fixing wire, and the soil box can be reinserted into the collection box to collect coal mine soil at different depths.

[0004] In the above application, since the drill bit is in the soil, the soil box is squeezed by the soil. It is difficult to fully open the soil box only by the rotating motor to spread the fixing wire, which affects the sampling of coal mine soil.

[0005] Therefore, a coal reserve surveying and mapping device is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a coal reserve surveying and mapping device to solve the above problems and improve the problem that it is difficult to fully open the soil box.

[0007] The present utility model realizes the above object through the following technical solutions. A coal reserve surveying and mapping device includes: a surveying vehicle, on the upper end surface of which an electric push rod is fixedly connected. The telescopic end of the electric push rod is fixedly connected with a connecting plate, and a drill rod is rotatably connected to the inner wall of the connecting plate; a sampling mechanism, which is arranged at the lower end of the surface of the drill rod. Among them, the sampling mechanism includes collecting grooves annularly distributed on the inner wall of the drill rod. A first servo motor is fixedly connected to the inner wall of the drill rod, and an output shaft of the first servo motor is fixedly connected with a retaining frame. An annular hole is opened at the lower end of the inner wall of the drill rod, and the annular hole communicates with the collecting groove. The surface of the retaining frame is slidably connected to the inner wall of the annular hole, and annularly distributed crushing frames are fixedly connected to the surface of the drill rod. Through the crushing frames, when the drill rod moves up and down, the soil is loosened and enters the open collecting grooves through the crushing frames. Through the annular hole, the collecting groove, the retaining frame and the first servo motor, one of the collecting grooves can be fully opened. Compared with the existing method of making the soil box fully open in the soil by dispersing the fixing wires, this method is convenient for fully opening one of the collecting grooves, ensuring the sampling efficiency of the coal mine soil.

[0008] Preferably, a fixing rod is fixedly connected to the upper end surface of the retaining frame, and annularly distributed sliding rods are slidably connected to the inner wall of the drill rod. One end of each sliding rod is fixedly connected with a spring, and the other end of the spring is fixedly connected to the inner wall of the drill rod. Through the spring, the sliding rod and the fixing rod, the rotation angle of the retaining frame is limited, facilitating the full opening of one of the collecting grooves.

[0009] Preferably, a movable block is fixedly connected to the upper end surface of the retaining frame, and annularly distributed elastic blocks are fixedly connected to the inner wall of the retaining frame. Through the movable block and the elastic blocks, the rotation angle of the retaining frame is limited, so that the openings on the retaining frame do not lie in any of the collecting grooves, thereby fully blocking the four collecting grooves.

[0010] Preferably, annularly distributed soil-breaking knives are fixedly connected to the surface of the drill rod, and the lower end of the surface of the drill rod is conical.

[0011] Preferably, the bottom of the crushing frame forms an angle with the horizontal plane.

[0012] Preferably, equally spaced fixed knives are fixedly connected to the surface of the crushing frame, and both the fixed knives and the soil-breaking knives are made of stainless steel components. Through the soil-breaking knives and the fixed knives, it is convenient to cut the coal mine soil more comprehensively, make the soil looser, and then facilitate the introduction of the soil into one of the collecting grooves.

[0013] Preferably, one ends of the sliding rod and the fixing rod are bent into an arc shape.

[0014] The beneficial effects of the present utility model are:

[0015] 1. The crushing frame allows the loosened soil to enter the open collection trough through the crushing frame during the up and down movement of the drill rod. The annular hole, the collection trough, the retaining frame, and the first servo motor enable one of the collection troughs to be fully opened. Compared with the existing method of fully opening the soil box in the soil by loosening the fixing wire, which is more difficult, this method facilitates the full opening of one of the collection troughs, ensuring the sampling efficiency of the coal mine soil.

[0016] 2. The spring, slide bar and fixed bar are used to limit the rotation angle of the baffle frame, so that one of the collection slots can be fully opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figures 1-5As shown in the figure, a coal reserve surveying and mapping device includes: a surveying vehicle 1, an electric push rod 2 is fixedly connected to the upper end of the surface of the surveying vehicle 1, a connecting plate 3 is fixedly connected to the telescopic end of the electric push rod 2, and a drill rod 4 is rotatably connected to the inner wall of the connecting plate 3; a sampling mechanism 5, the sampling mechanism 5 is arranged at the lower end of the surface of the drill rod 4; wherein, the sampling mechanism 5 includes collecting grooves 51 annularly distributed on the inner wall of the drill rod 4, a first servo motor 53 is fixedly connected to the inner wall of the drill rod 4, a retaining frame 52 is fixedly connected to the output shaft of the first servo motor 53, an annular hole 54 is opened at the lower end of the inner wall of the drill rod 4, the annular hole 54 is communicated with the collecting groove 51, the surface of the retaining frame 52 is slidably connected to the inner wall of the annular hole 54, and annularly distributed crushing frames 55 are fixedly connected to the surface of the drill rod 4, and the bottom of the crushing frame 55 forms an angle with the horizontal plane.

[0025] A collecting frame is fixedly connected to the top of the surveying vehicle 1, a vacuum cleaner is fixedly connected to the top of the collecting frame, a dust suction pipe is communicated with one side of the collecting frame, a circular frame is embedded and installed on the top of the surveying vehicle 1, the other end of the dust suction pipe penetrates through the surveying vehicle 1 and extends to the inner wall of the circular frame, a second servo motor is fixedly connected to the top of the connecting plate 3, a connecting rod is fixedly connected to the output shaft of the second servo motor, and the bottom end of the connecting rod is fixed to the drill rod 4 by bolts.

[0026] When it is necessary to survey the underground coal reserves in a coal mine, the surveying vehicle 1 is pushed to the location to be surveyed, the second servo motor and the electric push rod 2 are manually turned on. The output shaft of the second servo motor rotates to drive the drill rod 4 to rotate, and the telescopic end of the electric push rod 2 moves downward to drive the connecting plate 3 and the rotating drill rod 4 downward, so that the drill rod 4 drills into the coal mine soil to a corresponding depth. The first servo motor 53 is automatically turned on. The output shaft of the first servo motor 53 rotates to drive the retaining frame 52 to rotate. After the retaining frame 52 rotates to an appropriate angle, the opening of the retaining frame 52 is communicated with one of the collecting grooves 51, so that one of the collecting grooves 51 is opened. At this time, the electric push rod 2 is manually turned on to move the telescopic end of the electric push rod 2 up and down to an appropriate position. During the up and down movement of the telescopic end of the electric push rod 2, the connecting plate 3, the drill rod 4 and the crushing frame 55 are driven to move up and down. During the up and down movement of the crushing frame 55, the soil is loosened, and the soil is introduced into the opened collecting groove 51 through the inclined downward crushing frame 55. According to the above process, the four collecting grooves 51 collect soil samples at different depths in the coal mine soil. After the collection is completed, the drill rod 4 is moved up to the top of the surveying vehicle 1 through the electric push rod 2. At this time, the second servo motor and the electric push rod 2 are manually turned off, and the bolt is rotated to separate the connecting rod from the drill rod 4, so as to remove the soil in the collecting groove 51 and conduct inspections, so as to judge the approximate thickness and reserves of the underground coal.

[0027] As Figures 4-5As shown, a fixing rod 59 is fixedly connected to the upper end of the surface of the retaining frame 52. A plurality of sliding rods 58 distributed in a ring are slidably connected to the inner wall of the drill rod 4. One end of the sliding rod 58 is fixedly connected to a spring 510, and the other end of the spring 510 is fixedly connected to the inner wall of the drill rod 4. One end of the sliding rod 58 and the fixing rod 59 are bent in an arc shape.

[0028] The rotation of the retaining frame 52 drives the fixing rod 59 to move in a circle. When the fixing rod 59 moves and touches one end of one of the sliding rods 58, the first servo motor 53 automatically shuts down, causing one of the collecting grooves 51 to open. After one of the collecting grooves 51 has collected the soil, the first servo motor 53 is automatically turned on. The output shaft of the first servo motor 53 rotates to drive the fixing rod 59 to move in a circle. During the movement of the fixing rod 59, it touches one of the sliding rods 58 and makes it move inside the drill rod 4, so that the fixing rod 59 moves away from the surface of one of the sliding rods 58.

[0029] As Figures 4-5 shown, a movable block 512 is fixedly connected to the upper end of the surface of the retaining frame 52, and a plurality of elastic blocks 511 distributed in a ring are fixedly connected to the inner wall of the retaining frame 52.

[0030] After the overall sampling is completed, the rotation of the retaining frame 52 drives the movable block 512 to move in a circle. During the circular movement of the movable block 512, it touches one of the elastic blocks 511, so that the retaining frame 52 completely seals the four collecting grooves 51.

[0031] As Figure 4 shown, a plurality of earth-breaking knives 56 distributed in a ring are fixedly connected to the surface of the drill rod 4. The lower end of the surface of the drill rod 4 is conical. A plurality of fixed knives 57 distributed in equal rows are fixedly connected to the surface of the crushing frame 55. Both the fixed knife 57 and the earth-breaking knife 56 are made of stainless steel components.

[0032] When the present utility model is in use, the survey vehicle 1 is pushed to the location to be surveyed. The second servo motor and the electric push rod 2 are manually turned on. The output shaft of the second servo motor rotates to drive the drill rod 4 to rotate. The telescopic end of the electric push rod 2 moves downward to drive the connecting plate 3 and the rotating drill rod 4 to move downward, so that the rotating drill rod 4 and the earth-breaking knife 56 drill into the coal mine soil to a corresponding depth. The first servo motor 53 is automatically turned on. The output shaft of the first servo motor 53 rotates to drive the retaining frame 52 to rotate. The rotation of the retaining frame 52 drives the fixing rod 59 to move in a circle. When the fixing rod 59 moves and touches one end of one of the sliding rods 58, the first servo motor 53 automatically shuts down, causing one of the collecting grooves 51 to open. At this time, the electric push rod 2 is manually turned on to make the telescopic end of the electric push rod 2 move up and down to a suitable position. During the up and down movement of the telescopic end of the electric push rod 2, it drives the connecting plate 3, the drill rod 4 and the crushing frame 55 to move up and down. During the up and down movement of the crushing frame 55, the soil is loosened, so that the soil is introduced into the open collecting groove 51 through the inclined downward crushing frame 55. According to the above process, the four collecting grooves 51 collect soil samples at different depths in the coal mine soil.

[0033] It should be noted that in the above description, the survey vehicle 1, the electric push rod 2, the drill pipe 4, the first servo motor 53, the second servo motor, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply for the electric push rod 2, the first servo motor 53, and the second servo motor can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
