Description

Technical Field

[0001] This utility model relates to a buried pipe device for mining blasting, which can improve drilling accuracy and belongs to the field of mining equipment technology. Background Technology

[0002] Mining blasting involves placing explosives within underground ore bodies or rocks, using the energy of the explosion to break the ore or rock, thereby enabling ore extraction and mining. Before blasting, a mining blasting pipe-laying device is typically used to drill holes in level ground, and then the blasting pipe is installed into the holes. Mining blasting pipe-laying devices not only precisely control the release and direction of blasting energy, but also improve blasting efficiency, reduce environmental impact, and ensure worker safety.

[0003] After existing pipe-laying devices are moved to the designated location, the brakes on the traveling wheels are typically engaged by foot to secure the device before drilling and installing the blasting pipe. However, when drilling in harder soil areas, the reaction force of the soil on the drilling device is significant, and the braking force of the traveling wheel brakes is limited. This causes the pipe-laying device to move laterally during drilling, which not only compromises drilling accuracy but also easily damages the device. Therefore, it is essential to improve existing pipe-laying devices used in mining blasting. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a buried pipe device for mining blasting, thereby improving drilling accuracy and extending equipment service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A burial pipe device for mining blasting includes a mobile trolley. A storage box is fixed to the rear of the upper surface of the mobile trolley. A horizontal support plate is fixed to the front wall of the storage box. A horizontal sliding plate is provided between the support plate and the mobile trolley. The sliding plate is connected to the support plate by a vertical hydraulic rod. A drilling device is installed in the middle of the sliding plate. Stabilizing devices are symmetrically arranged on both sides. Each stabilizing device includes a horizontal rotating shaft, a gear, a rack column, a bent arm, and a plug rod. The gear is fixed in the middle of the horizontal rotating shaft, and its two ends are rotatably connected to the fixed frame of the mobile trolley. The rack column meshes with the gear.

[0019] To overcome the shortcomings of existing technologies, this utility model provides a buried pipe device for mining blasting. This device effectively solves the problems of existing buried pipe devices being not securely fixed, resulting in low drilling accuracy and easy damage to the device.

[0020] See Figure 1 , Figure 2 and Figure 3 This utility model includes a mobile cart 1, a storage box 2 fixedly connected to the rear of the upper surface of the mobile cart 1, a horizontal support plate 3 fixedly connected to the front wall of the storage box 2, a horizontal sliding plate 5 between the support plate 3 and the mobile cart 1, a vertical hydraulic rod 4 fixedly connected to the upper surface of the support plate 3, the output end of the hydraulic rod 4 connected to the sliding plate 5, a vertical limiting rod 6 fixedly connected to the upper surface of the sliding plate 5, the limiting rod 6 slidingly passing through the through hole on the support plate 3 and having a limiting plate at its top, a motor 7 fixedly connected to the upper surface of the sliding plate 5, and a screw conveyor drill bit 8 at the lower part of the sliding plate 5, the upper end of the screw conveyor drill bit 8 fixedly connected to the output end of the motor 7, the lower end passing through the through hole on the mobile cart 1 and facing the ground, and the screw conveyor drill bit 8 rotatably connected to the sliding plate 5.

[0021] A symmetrical fixed frame 9 is fixedly connected to the front of the upper surface of the mobile cart 1. A horizontal rotating shaft 10 is rotatably connected inside the fixed frame 9. A gear 11 is fixedly connected to the outer wall of the horizontal rotating shaft 10. A rack column 12 that meshes with each gear 11 is fixed on the left and right sides of the sliding plate 5. A sliding sleeve 14 corresponding to each rack column 12 is fixed on the mobile cart 1. The lower end of the rack column 12 is slidably inserted into the corresponding sliding sleeve 14. A stabilizing component 13 is provided on the outer wall of each horizontal rotating shaft 10. The stabilizing component 13 includes a bent arm 1301, a fixed plate 1302 and an insertion rod 1303. One end of the bent arm 1301 is fixedly connected to the horizontal rotating shaft 10, and the other end is fixedly connected to one side of the fixed plate 1302. The other side of the fixed plate 1302 is fixedly connected to the insertion rod 1303. When the bent arm 1301 rotates around the horizontal rotating shaft 10, it can drive the insertion rod 1303 to be lifted or inserted into the ground.

[0022] When the hydraulic rod 4 is activated, it drives the sliding plate 5 to rise and fall. Simultaneously, the motor 7 is activated, causing the auger drill bit 8 to rotate. As the sliding plate 5 descends, the rack column 12 slides inside the sliding sleeve 14, thereby driving the gear 11 to mesh and rotate. The gear 11 also drives the rotation of the curved arm 1301 on the outer wall of the horizontal rotating shaft 10. During the rotation of the curved arm 1301 driven by the gear 11, the fixed plate 1302 rotates synchronously. The fixed plate 1302 drives the insertion rod 1303 to rotate and insert into the soil. At the same time, the auger drill bit 8 continues to rotate under the drive of the motor 7, performing drilling operations.

[0023] See Figures 1-4 The storage box 2 has a guide block 15 fixedly connected inside, and multiple supports 16 fixedly connected to the bottom of the storage box 2. The lower surface of the supports 16 is fixedly connected to the upper surface of the mobile cart 1. Their function is to support the storage box 2 and related components, ensuring the stability of the entire device, and allowing the storage box 2 and the mobile cart 1 to move together, facilitating the adjustment and operation of the equipment. The top inlet of the storage box 2 is rotatably connected to symmetrical protective doors 17, which are used to protect the internal components and prevent external factors from interfering with or damaging them. The upper surface of each of the two protective doors 17 is fixedly connected to a handle 18, which makes it easy for operators to open and close the protective doors 17, improving the ease of use of the equipment. A U-shaped discharge hopper 19 is fixedly connected to the discharge port at the lower part of the outer wall of the storage box 2. The two side walls of the discharge hopper 19 are fixedly connected to the outer side of the mounting sleeves 20; the inner wall of the discharge hopper 19 is slidably connected to the baffle 21, and the upper end of the baffle 21 is fixedly connected to the handle 22, which allows the operator to manually adjust the position of the baffle 21, thereby precisely controlling the discharge process; both sides of the upper end of the baffle 21 are provided with pins that match the mounting sleeves 20. The pins are slidably inserted into the mounting sleeves 20. The mounting sleeves 20 are used to fix the position of the baffle 21, preventing material leakage while ensuring that the material is discharged as needed; the top of the guide block 15 is provided with a V-shaped bursting tube guide groove. The bottom of the bursting tube guide groove is opposite to the discharge hopper 19. The guide block 15 is used to guide the bursting tube smoothly into the predetermined position, preventing it from deviating during operation and improving the safety of operation.

[0024] Working principle: When the pipe-burying device is needed, push the device to the area where the pipe needs to be buried, start the hydraulic rod 4, and the hydraulic rod 4 drives the sliding plate 5 to rise and fall. At the same time, start the motor 7 to drive the auger drill bit 8 to rotate. As the sliding plate 5 descends, it drives the rack column 12 to slide inside the sliding sleeve 14. The rack column 12 drives the insertion rod 1303 to rotate in sequence through the gear 11, horizontal rotating shaft 10, bent arm 1301, and fixed plate 1302. Finally, the insertion rod 1303 is inserted into the soil to achieve the effect of fixing the device. At the same time, the auger drill bit 8 descends to carry out drilling operations.

[0025] Before use, multiple bursting tubes can be placed inside the storage box 2. The bursting tubes can be guided to the discharge hopper 19 in sequence through the bursting tube guide groove on the guide block 15. Then, by pulling the handle 22 to lift the baffle 21, the bursting tubes can be quickly removed.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
