AI Technical Summary
During the drilling process of the anchor drilling rig, water and dust are sprayed out in large quantities, resulting in inconvenience in construction and harsh environment, which has a serious impact on the physical and mental health of the construction personnel. The existing dustproof devices have complex structures, inconvenient installation and disassembly, and high prices, which increases production costs.
The connecting sleeve, sealing ring and water sleeve are used to fix it on the main shaft or drill rod of the anchor drill rig. The sheath and connection sleeve are quickly connected through the flange. The structure is simple, the disassembly and installation are easy to install, and it effectively prevents dust from overflowing.
The dustproof effect of anchor drilling rig is achieved, the construction environment is purified, the physical and mental health of construction personnel is protected, the production costs are reduced, and the production safety and efficiency are improved.

Abstract
Description
Technical field:
[0001] The utility model relates to a dust cover for an anchor drill used when drilling holes underground in a coal mine. Background technology:
[0002] Anchor support is one of the necessary protective measures in the mining production process. When installing anchors, anchor holes must be drilled with an anchor drill. At present, during the process of drilling anchor holes, a large amount of water and dust are sprayed out, which makes construction inconvenient and the working environment harsh, causing serious impacts on the physical and mental health of construction workers. Selenium lung disease is one of their occupational diseases. Therefore, it is very necessary to install dust prevention devices on anchor drills. However, the dust prevention devices currently used are generally complex in structure, inconvenient to install and disassemble, and expensive, which increases production costs. Utility model content:
[0003] The technical problem to be solved by the utility model is to provide a dust cover for anchor drilling rigs that is fixed on the main shaft or drill rod of the anchor drilling rig by a connecting sleeve, a sealing ring and a water jacket, which is easy to disassemble and install, can prevent dust from overflowing, purify the construction environment, and protect the physical and mental health of construction workers. The flange is used to quickly connect the fixing sleeve and the connecting sleeve, which has a simple structure, saves costs, and greatly improves production safety and efficiency.
[0004] The technical solution adopted by the utility model to solve the above technical problems is: the connecting sleeve of the dust cover of the anchor drilling rig is movably connected with the sleeve through a flange, bolts and a sleeve, an elastic sealing ring is arranged at the left top end of the sleeve, the supporting compression sleeve is movably arranged at the left outer end of the sleeve, and the sealing ring is movably built into a groove in the middle of the right outer end of the connecting sleeve.
[0005] The beneficial effects of the utility model are as follows: since the utility model adopts a connecting sleeve, a sealing ring and a water jacket to be fixed on the main shaft or the drill rod of the anchor drilling rig, it is easy to disassemble and install, can prevent dust from overflowing, purify the construction environment, and protect the physical and mental health of the construction personnel. The flange is used to quickly connect the fixed sleeve and the connecting sleeve, which has a simple structure, saves costs, and greatly improves production safety and efficiency. Description of the drawings:
[0006] Figure 1 It is a structural schematic diagram of the utility model.
[0007] Figure 2 yes Figure 1 Right view of . Specific implementation method:
[0008] Example 1: Figure 1 , Figure 2As shown, the connecting sleeve 7 of the dust cover of the anchor drilling rig is movably connected to the sleeve 1 through the flange 4, bolts, and the sleeve 1. An elastic sealing ring 2 is arranged at the left top end of the sleeve 1, a supporting compression sleeve 3 is movably arranged at the left outer end of the sleeve 1, and a sealing ring 6 is movably built into a groove in the middle of the right outer end of the connecting sleeve 7.
[0009] Example 2: Figure 1 , Figure 2 As shown, the right inner end of the connecting sleeve 7 of the anchor drill dust cover is connected to the drilling rig anchor water jacket 5 by screws, and the right end of the drilling rig anchor water jacket 5 is fixedly connected to the drilling rig anchor.
[0010] Embodiment 3: The operation method of the utility model:
[0011] When using the utility model, firstly, the rubber high elastic sealing ring at the front end of the sheath is pressed against the outer periphery of the drill hole of the rock mass, thereby sealing the drill hole and the drill rod. Then, the connecting sleeve matching the drilling rig anchor rod is movably connected to the sheath through the flange, and then the connecting sleeve matching the drilling rig anchor rod and the water jacket on the anchor drilling rig are fixed with screws, and the sealing ring is set in the groove at the outer end of the connecting sleeve matching the drilling rig anchor rod, thereby sealing dust, water, slag and gas. After drilling, the drill bit and the drill rod can be pulled out.
[0012] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
