TECHNICAL FIELD
[0001] The utility model belongs to the technical field of drilling equipment, and particularly relates to a drilling equipment with dust capturing effect for mine. BACKGROUND
[0002] In the process of mining, drilling operation is a necessary step to obtain ore resources. However, drilling operation is often accompanied by the generation of a large amount of dust, which not only seriously affects the line of sight of the operating personnel, increases the operation difficulty, but also may cause long-term damage to the respiratory system of the operating personnel, and even cause occupational diseases such as pneumoconiosis. In order to deal with the dust pollution problem in drilling operation, wet dust removal mode is widely used. Wet dust removal sprays water mist or water flow to the drilling area, so that dust particles combine with water and settle, thereby achieving the purpose of reducing dust concentration.
[0003] However, the application of the traditional wet dust removal equipment in the mine drilling operation has many limitations. First, in order to provide sufficient water pressure and flow to form effective water mist or water flow, additional spraying power equipment such as water pump and pipeline is usually required. The addition of these devices not only increases the cost, volume and weight of the drilling device, but also makes it difficult to carry and use the device in the narrow space underground. SUMMARY
[0004] In view of the above problems, the purpose of the utility model is to provide a drilling equipment with dust capturing effect for mine, which solves the problem that the existing drilling dust removal through wet dust removal mode requires additional spraying power equipment, which excessively increases the cost and volume of the device, and is not conducive to the carrying and use of the device in the narrow space underground.
[0005] To achieve the above purpose, the utility model adopts the technical scheme: a drilling equipment with dust capturing effect for mine, comprising a base, a sleeve is installed on the base, an atomization dust capturing assembly is installed on the bottom side of the sleeve, a through hole is formed in the upper side of the sleeve and a fixing frame is welded and fixed, a sealing cover is installed on the top of the sleeve, the sealing cover is sleeved on the outside of a sliding rod, a piston is installed at the bottom end of the sliding rod, the piston is installed on the inside of the sleeve, a moving frame is installed at the top end of the sliding rod, a motor is installed on the moving frame, the motor is drivingly connected with a screw rod, a drill bit is installed at the bottom end of the screw rod and a nut is threadedly connected with the screw rod, and the nut is installed on the fixing frame.
[0006] The utility model has the advantages that: by utilizing the screw pair motion principle of the screw rod and the nut, combining the linkage of the sliding rod, the piston and the sleeve, the drilling and spraying are simultaneously performed, the device structure is simplified, and the energy consumption and cost are reduced.
[0007] In order to effectively store water in the sleeve;
[0008] As a further improvement of the above technical solution: the atomization dust collection assembly comprises an outer shell, one end of the outer shell is connected with a water inlet, the other end is threadedly connected with a spray head, the water inlet is threadedly connected with a sleeve, a hollow limiting frame is connected between the water inlet and the inner end face of the outer shell, a plug and a spring are slidingly installed on the inner side of the hollow limiting frame, the plug is a conical structure.
[0009] The beneficial effect of the improvement is that under the support of the spring force, the thinner end of the plug can be inserted into the water inlet, avoiding the water in the sleeve from being discharged through the atomization dust collection assembly under the action of its own water pressure, thereby preventing water leakage.
[0010] In order to conveniently add water to the atomization dust collection assembly;
[0011] As a further improvement of the above technical solution: the sleeve is threadedly connected with a sealing cover.
[0012] The beneficial effect of the improvement is that the sealing cover can be quickly connected and separated from the sleeve through the threaded structure, thereby facilitating personnel to add water to the inside of the sleeve.

[0014] As a further improvement of the above technical solution: a dynamic sealing ring is arranged on the side surface of the piston in sliding fit with the sleeve.
[0015] The beneficial effect of the improvement is that the movement of the piston can effectively extrude the water in the lower sleeve.
[0016] In order to ensure the safety of the device during drilling operation;
[0017] As a further improvement of the above technical solution: handles are connected to both ends of the fixing frame.
[0018] The beneficial effect of the improvement is that the operator can hold the handles to safely use the device for drilling operation.
[0019] In order to ensure the safety of the device during drilling operation;
[0020] As a further improvement of the above technical solution: the base is a ring plate structure, the number of sleeves is two and they are symmetrically arranged on both sides of the base axis.
[0021] The beneficial effect of the improvement is that the relatively arranged atomization dust collection assemblies in cooperation with the use of the slide rod can enable the operator to stably control the device when holding the handles, thereby performing safe drilling operation.
[0022] The parts not involved in the device are the same as or can be realized by the existing technology. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0028] In order to make the person skilled in the art better understand the technical scheme of the present application, the present application will be described in detail below in conjunction with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present application.
[0029] Example 1:
[0030] As Figure 1As shown in Figure 4: A drilling device for mining with dust collection effect includes a base 1, a sleeve 2 mounted on the base 1, an atomizing dust collection component 3 mounted on the bottom side of the sleeve 2, a fixed frame 4 welded through the upper side of the sleeve 2, a sealing cover 5 mounted on the top of the sleeve 2, the sealing cover 5 slidably fitted on the outside of a slide rod 6, a piston 7 mounted on the bottom end of the slide rod 6, the piston 7 mounted on the inside of the sleeve 2, a movable frame 11 mounted on the top of the slide rod 6, and a motor 12 mounted on the movable frame 11, the motor 12 driving the connection... The device includes a screw 9, with a drill bit 10 mounted at its bottom end and a nut 8 threadedly connected to the screw 9. The nut 8 is mounted on a fixed frame 4. Utilizing the helical pair motion principle of the screw 9 and nut 8, combined with the linkage of the slide rod 6, piston 7, and sleeve 2, drilling and spraying are synchronized, simplifying the equipment structure and reducing energy consumption and cost. The atomizing dust collection component 3 includes a housing 31, with a water inlet 32 connected to one end and a nozzle 36 threadedly connected to the other end. The water inlet 32 is threadedly connected to the sleeve 2. A perforated limiting bracket 33 is connected between the inner end faces of the outer shell 31. A plug 34 and a spring 35 are slidably installed on the inner side of the perforated limiting bracket 33. The plug 34 has a conical structure. Under the elastic support of the spring 35, the thinner end of the plug 34 can be inserted into the water inlet 32 to prevent water in the sleeve 2 from being discharged through the atomizing dust collection component 3 under its own water pressure, thus preventing water leakage. The sleeve 2 is threadedly connected to a sealing cap 5. The sealing cap 5 can be quickly connected and separated from the sleeve 2 through the threaded structure, thereby facilitating personnel to add water to the inside of the sleeve 2. Water is added. The piston 7 has a dynamic sealing ring on its side that slides with the sleeve 2. The movement of the piston 7 can effectively squeeze out the water in the lower sleeve 2. Both ends of the fixed frame 4 are connected to handles 41. The operator can hold the handles 41 to safely use the device for drilling. The base 1 has an annular plate structure. There are two sleeves 2, which are symmetrically arranged on both sides of the axis of the base 1. The atomizing dust collection components 3 arranged opposite each other, together with the sliding rod 6, can allow the operator to stably control the device when holding the handles 41 and perform safe drilling operations.
[0031] The working principle of this technical solution is as follows: Move the device to a suitable drilling position, then hold the handle 41 to start the motor 12, which drives the screw 9 to rotate. When the screw 9 rotates, it is limited by the slide rod 6, thereby generating a helical pair motion with the nut 8, which drives the drill bit 10 to move downward while rotating, so as to carry out drilling work. During the process of the slide rod 6 moving downward synchronously with the screw 9 and the moving frame 11, the piston 7 installed at the bottom of the slide rod 6 squeezes the water filling the sleeve 2. The water transmits pressure to push the plug 34, causing the plug 34 to move away from the water inlet 32 and squeeze the spring 35, thereby allowing the water to enter the outer shell 31 and spray it onto the periphery of the drill bit 10 through the nozzle 36. During the drilling process, atomization and dust removal are achieved. The drilling and spraying are carried out synchronously through the power output of a single motor, which effectively reduces the size and weight of the device.
