Description
Technical Field
[0001] This utility model relates to the technical field of coal sampling equipment, and in particular to a coal sampling device with dust reduction function. Background Technology
[0002] Coal mines are areas where coal is concentrated and mined. Coal is a major solid fuel that originated from the abundant vegetation of past geological eras. When these plants gradually accumulated and were buried in water or silt under suitable geological conditions, they formed coal through long-term natural processes. To ensure the quality of the coal produced, it is necessary to sample and test the coal mine.
[0003] Currently, existing coal sampling devices, such as the coal sampling device with dust suppression function disclosed in patent publication number CN221803452U, include a vehicle platform. A push rod is fixedly connected to one side of the top of the vehicle platform. An opening is formed through the vehicle platform. Two electric cylinders are symmetrically fixedly connected to the top of the vehicle platform. The telescopic ends of the two electric cylinders are fixedly connected to a lifting frame. A rotating rod is rotatably connected to the lifting frame. A motor is fixedly connected to the lifting frame. The top of the rotating rod is fixedly connected to the rotating end of the motor. A sampling drill bit is fixedly connected to the bottom of the rotating rod. A spiral blade is fixedly sleeved on the rotating rod. When the sampling drill bit rotates to sample, a delivery pump works to draw water from the water tank through the inlet pipe and deliver it to the hose through the outlet pipe. Then, it is delivered to the annular pipe through the hose. Finally, water mist is sprayed out through a water mist nozzle to suppress the coal dust raised by the sampling drill bit, so that the raised coal dust settles down with the water mist, reducing the diffusion and flying of coal dust.
[0004] The coal sampling device in the aforementioned patent also has certain drawbacks in use. The push rod, which is fixedly connected to one side of the top of the vehicle, has a fixed height and cannot be adjusted, making it inconvenient for workers of different heights to use and thus lacking practicality. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a coal sampling device with dust reduction function that can adjust the height of the push rod, making it more convenient for workers of different heights to use and improving its practicality.
[0006] Technical solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: A coal sampling device with dust reduction function, comprising a vehicle platform, a push rod assembly, and a positioning mechanism. The vehicle platform has a through-hole, and a sampling bucket is placed on the top of the vehicle platform. The push rod assembly includes two sets of support rods, which are symmetrically and fixedly connected to the left side of the top of the vehicle platform. A positioning plate is integrally fixed to the top of each set of support rods. A connecting rod is fixedly connected between the two sets of support rods, and a U-shaped push rod is rotatably mounted on the connecting rod. The positioning mechanism includes a fixing frame, which is fixedly connected to the U-shaped push rod. The left and right ends of the fixing frame are horizontal to the left and right ends of the U-shaped push rod. The fixing frame contains... Two sets of limiting grooves are provided on the wall. A movable plate is slidably installed on the fixed frame through the cooperation of the limiting grooves. Two sets of springs are symmetrically fixed between the top of the movable plate and the outer wall of the U-shaped push rod. Two sets of T-shaped inserts for positioning are symmetrically slidably provided on the fixed frame. Two sets of transmission plates are symmetrically hinged at the bottom of the movable plate. The bottom of the two sets of transmission plates is respectively hinged to the inner side of the two sets of T-shaped inserts. Multiple sets of positioning holes are arranged in an array with the connecting rod as the axis on both sets of positioning plates. Two sets of sliding holes are symmetrically provided on the U-shaped push rod. Sliding sleeves are fixed in both sets of sliding holes. The two sets of T-shaped inserts pass through the two sets of sliding holes and are inserted into two sets of positioning holes through cooperation with the sliding sleeves.
[0008] Preferably, the top left side of the vehicle platform is provided with a fixing component for fixing the sampling bucket. The fixing component includes a fixing ring with a diameter larger than the outer diameter of the sampling bucket. The fixing ring is fixedly connected to the top left side of the vehicle platform. Two sets of elastic blocks are symmetrically fixed on the inner wall of the fixing ring. The sampling bucket is placed in the fixing ring by engaging with the elastic blocks. A knob bolt is screwed on one side of the fixing ring, and the right end of the knob bolt is pressed against the outer wall of the sampling bucket.
[0009] Preferably, a guide rod is fixedly connected between the U-shaped push rod and the fixed frame, and a guide hole is provided in the center of the movable plate. The movable plate is slidably fitted onto the guide rod through the cooperation of the guide hole.
[0010] Preferably, two sets of anti-slip grips are symmetrically fixed on the outer circumference of the U-shaped push rod, and the two sets of anti-slip grips are distributed on both sides of the fixed frame.
[0011] Preferably, a reinforcing rod is fixedly connected between the left end of each of the two sets of support rods and the top of the vehicle panel.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the operator can adjust the height of the U-shaped push rod according to their own height. During adjustment, hook the movable plate with your finger and pull the movable plate upward to slide it. This causes the movable plate to pull the T-shaped insert rod inward through the transmission plate. The spring is compressed, causing the T-shaped insert rod to disengage from the positioning hole. Then, rotate and adjust the U-shaped push rod to the appropriate height, aligning the T-shaped insert rod with the positioning hole at the corresponding position after adjustment. Then, release the movable plate. The spring rebounds and pushes the movable plate downward, causing the movable plate to push the T-shaped insert rod outward through the transmission plate, so that the T-shaped insert rod is inserted into the positioning hole at the corresponding position. This keeps the position of the adjusted U-shaped push rod unchanged, allowing the operator to hold the two sides of the outer wall of the U-shaped push rod and push the device to move it, thereby adjusting the height of the push rod. This makes it more convenient for operators of different heights to use and improves practicality. Attached Figure Description

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example 1
[0020] Please see Figures 1-5This utility model discloses a coal sampling device with dust reduction function, comprising a platform 1, a through opening in the platform 1, a sampling bucket 3 placed on the top of the platform 1, two sets of support rods 4 symmetrically fixedly connected to the left side of the top of the platform 1, and a positioning plate 5 integrally fixed at the top of each set of support rods 4, a connecting rod 6 fixedly connected between the two sets of support rods 4, a U-shaped push rod 7 rotatably mounted on the connecting rod 6, a fixing frame 8 fixedly connected to the U-shaped push rod 7, the left and right ends of the fixing frame 8 being horizontal with the left and right ends of the U-shaped push rod 7, and a mounting plate 5 on the inner wall of the fixing frame 8. Two sets of limiting grooves are provided. A movable plate 9 is slidably mounted on the fixed frame 8 through the cooperation of the limiting grooves. Two sets of springs 10 are symmetrically fixedly connected between the top of the movable plate 9 and the outer wall of the U-shaped push rod 7. Two sets of T-shaped inserts 11 for positioning are symmetrically slidably provided on the fixed frame 8. Two sets of transmission plates 12 are symmetrically hinged to the bottom of the movable plate 9. The bottom ends of the two sets of transmission plates 12 are respectively hinged to the inner sides of the two sets of T-shaped inserts 11. Multiple sets of positioning holes are arranged in an array around the connecting rod 6 on both sets of positioning discs 5. Two sets of sliding holes are symmetrically provided on the U-shaped push rod 7. Each hole is fixedly equipped with a sliding sleeve 19. Two sets of T-shaped insert rods 11, through cooperation with the sliding sleeves 19, pass through the two sets of sliding holes and are inserted into two sets of positioning holes respectively. During use, the operator can adjust the height of the U-shaped push rod 7 according to their own height. During adjustment, hook the movable plate 9 with your finger and pull it upwards to slide it. This causes the movable plate 9 to pull the T-shaped insert rods 11 inwards via the transmission strip 12, compressing the spring 10 and disengaging the T-shaped insert rods 11 from the positioning holes. Then, rotate and adjust the U-shaped push rod 7 to the appropriate height. Align the T-shaped insert 11 with the positioning hole at the corresponding position after adjustment, and then release the movable plate 9. The spring 10 rebounds and pushes the movable plate 9 downward, which in turn pushes the T-shaped insert 11 outward through the transmission strip 12, so that the T-shaped insert 11 is inserted into the positioning hole at the corresponding position. This keeps the position of the adjusted U-shaped push rod 7 unchanged, and the operator can hold the two sides of the outer wall of the U-shaped push rod 7 to push the device to move it, thereby adjusting the height of the push rod, making it more convenient for operators of different heights to use and improving its practicality. Example 2
[0021] Please see Figures 1-5This utility model discloses a coal sampling device with dust reduction function, comprising a platform 1, a through opening in the platform 1, a sampling bucket 3 placed on the top of the platform 1, two sets of support rods 4 symmetrically fixedly connected to the left side of the top of the platform 1, and a positioning plate 5 integrally fixed at the top of each set of support rods 4, a connecting rod 6 fixedly connected between the two sets of support rods 4, a U-shaped push rod 7 rotatably mounted on the connecting rod 6, a fixing frame 8 fixedly connected to the U-shaped push rod 7, the left and right ends of the fixing frame 8 being horizontal with the left and right ends of the U-shaped push rod 7, and a mounting plate 5 on the inner wall of the fixing frame 8. Two sets of limiting grooves are provided. A movable plate 9 is slidably mounted on the fixed frame 8 through the cooperation of the limiting grooves. Two sets of springs 10 are symmetrically fixedly connected between the top of the movable plate 9 and the outer wall of the U-shaped push rod 7. Two sets of T-shaped inserts 11 for positioning are symmetrically slidably provided on the fixed frame 8. Two sets of transmission plates 12 are symmetrically hinged to the bottom of the movable plate 9. The bottom ends of the two sets of transmission plates 12 are respectively hinged to the inner sides of the two sets of T-shaped inserts 11. Multiple sets of positioning holes are arranged in an array around the connecting rod 6 on both sets of positioning discs 5. Two sets of sliding holes are symmetrically provided on the U-shaped push rod 7. Each hole is fixedly equipped with a sliding sleeve 19. Two sets of T-shaped insert rods 11, through cooperation with the sliding sleeves 19, pass through the two sets of sliding holes and are inserted into two sets of positioning holes respectively. During use, the operator can adjust the height of the U-shaped push rod 7 according to their own height. During adjustment, hook the movable plate 9 with your finger and pull it upwards to slide it. This causes the movable plate 9 to pull the T-shaped insert rods 11 inwards via the transmission strip 12, compressing the spring 10 and disengaging the T-shaped insert rods 11 from the positioning holes. Then, rotate and adjust the U-shaped push rod 7 to the appropriate height. Align the T-shaped insert 11 with the positioning hole at the corresponding position after adjustment, and then release the movable plate 9. The spring 10 rebounds and pushes the movable plate 9 downward, which in turn pushes the T-shaped insert 11 outward through the transmission strip 12, so that the T-shaped insert 11 is inserted into the positioning hole at the corresponding position. This keeps the position of the adjusted U-shaped push rod 7 unchanged, and the operator can hold the two sides of the outer wall of the U-shaped push rod 7 to push the device to move it, thereby adjusting the height of the push rod, making it more convenient for operators of different heights to use and improving its practicality.
[0022] The top left side of the vehicle platform 1 is provided with a fixing component for fixing the sampling bucket 3. The fixing component includes a fixing ring 14, the diameter of which is larger than the outer diameter of the sampling bucket 3. The fixing ring 14 is fixedly connected to the top left side of the vehicle platform 1. Two sets of elastic blocks 15 are symmetrically fixed on the inner wall of the fixing ring 14. The sampling bucket 3 is placed in the fixing ring 14 by engaging with the elastic blocks 15. A knob bolt 16 is screwed on one side of the fixing ring 14, and the right end of the knob bolt 16 is pressed against the outer wall of the sampling bucket 3. When placing the sampling bucket 3, it can be placed in the fixing ring 14 so that the right side wall of the sampling bucket 3 abuts against the right inner wall of the fixing ring 14. The sampling bucket 3 squeezes the elastic blocks 15 to generate a clamping force, so that the elastic blocks 15 clamp the bottom of the sampling bucket 3 from both sides. Then, by rotating the knob bolt 16, the right end of the knob bolt 16 is pressed against the left outer wall of the sampling bucket 3, making the sampling bucket 3 more stable and preventing it from tipping over when the device is moved.
[0023] A guide rod 13 is fixedly connected between the U-shaped push rod 7 and the fixed frame 8. The movable plate 9 has a guide hole in the center. The movable plate 9 is slidably fitted onto the guide rod 13 through the cooperation of the guide hole. When the movable plate 9 is pulled to slide, it slides upward along the guide rod 13. Through the guidance of the guide rod 13 and the limiting groove, the movable plate 9 can be effectively prevented from detaching from the fixed frame 8, thus improving stability.
[0024] Two sets of anti-slip handle sleeves 17 are symmetrically fixed on the outer circumference of the U-shaped push rod 7, and the two sets of anti-slip handle sleeves 17 are distributed on both sides of the fixed frame 8. By setting the anti-slip handle sleeves 17, when the pushing device moves, both hands can hold the anti-slip handle sleeves 17 to push, and it is not easy for the hands to slip.
[0025] Both sets of support rods 4 are fixedly connected to the top of the vehicle plate 1 with reinforcing rods 18 at their left ends; by setting reinforcing rods 18, the connection between the support rods 4 and the vehicle plate 1 can be made more secure and stable.
[0026] This utility model discloses a coal sampling device with dust reduction function. In operation, the height of the U-shaped push rod 7 can be adjusted according to the user's height. During adjustment, the user hooks their finger onto the movable plate 9 and pulls it upwards, causing the movable plate 9 to pull the T-shaped insert rod 11 inwards via the transmission strip 12. This compresses the spring 10, disengaging the T-shaped insert rod 11 from the positioning hole. The user then rotates and adjusts the U-shaped push rod 7 to the appropriate height, aligning the T-shaped insert rod 11 with the corresponding positioning hole after adjustment. Finally, the user releases the movable plate 9, and the spring 10 rebounds. The movable plate 9 moves downward, which in turn pushes the T-shaped insert 11 outward through the transmission bar 12, so that the T-shaped insert 11 is inserted into the positioning hole at the corresponding position, thereby keeping the adjusted U-shaped push rod 7 in a constant position. The operator can then hold the two sides of the outer wall of the U-shaped push rod 7 and push the device to move it. The remaining structures on the vehicle plate have been described in detail in a coal sampling device with dust reduction function disclosed in patent publication number CN221803452U. The working principle of the device during sampling has also been described in detail, so it will not be elaborated further.
[0027] The coal sampling device with dust reduction function of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
