[0030] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] In order to ensure the normal drilling of the drill rod underground, an air duct is usually set inside the drill rod. The waste soil and debris generated by the drill rod drilling are sprayed out of the hole by injecting air flow into the drill rod from the outside. The dust generated by this working method will always disperse to the outside due to the internal airflow, causing great pollution to the construction environment.

[0032] To solve the above problems, see Figures 1 to 12 Provided is a hole-opening device for coal mining with an anti-vibration function, comprising: a lifting frame 10, a drill rod 20 fixed at the center position of a lifting platform 11, and a water tank 30 located below the drill rod 20.

[0033] Specifically, one side of the lifting frame 10 is provided with a lifting platform 11 that can be lifted vertically, the lower end surface of the lifting frame 10 is provided with a positioning pin 13 for inserting into the ground and a nozzle 141 for spraying an annular water curtain, the drill rod 20 passes through the center position of the nozzle 141, the water tank 30 is connected with the nozzle 141, a plurality of water filter plates 362 are provided inside the water tank 30, the outer wall of the water tank 30 is provided with a slot 36 that fits with the side wall of the water filter plate 362, the upper end surface of the water filter plate 362 has at least two baffles 1 42 and baffle 2 43 that are inclined in the same direction, the water sprayed by the nozzle 141 falls between the baffle 2 43 and the inner wall of the water tank 30, the baffle 1 42 is away from the baffle 2 43 and extends through the slot 36 to the outside of the water tank 30, the vibration generated when the drill rod 20 drills the ground drives the water tank 30 to shake, so as to drive the waste material wetted and agglomerated by water to be shaken out of the water tank 30 from the baffle 1 42.

[0034] When the drill rod 20 is working, the whole lifting frame 10 will generate a certain vibration, and the vibration will cause the water tank 30 below it to vibrate. When the drill rod 20 rotates, the reverse impact airflow generated by the air cavity inside the drill rod 20 blowing air from the drill hole will blow out the waste soil inside the drilled hole. The blown waste soil will splash and hit the water curtain sprayed by the nozzle 141, and will be knocked down by the water curtain and fall between the baffle plate 2 43 and the inner wall of the water tank 30, and the water filter plate 1 362 will filter the water here and drop it to the lower layer, while the larger particles of soil will be on the upper side. When the soil debris accumulates to a certain extent, it will slowly move outward due to the effect of vibration. Since the impact point of the fall is at the position of baffle plate 2 43, and since baffle plate 1 42 and baffle plate 2 43 are both inclined, the moving soil debris can only move to the side close to the slot 36 until the cavity between baffle plate 1 42 and baffle plate 2 43 is slowly filled. When the soil debris accumulates to a certain extent, it will fall from the position of the slot 36, and water is always filtered in this process, which can greatly reduce the loss of water source in the water tank 30 and make full use of the water source.

[0035] In order to further improve the relevant structure of the nozzle 141, please refer to Figures 1 to 3 A front frame 14 and a rear frame 12 are provided at the bottom of the lifting frame 10, a nozzle 141 is provided on the lower end surface of the front frame 14, a positioning pin 13 is penetrated and provided on the surface of the rear frame 12, a water pump 142 is provided on the upper end surface of the front frame 14, a liquid outlet side of the water pump 142 is connected to a liquid inlet of the nozzle 141, a liquid pipe 143 is connected to the other side of the water pump 142, and the other end of the liquid pipe 143 is inserted into the interior of the water tank 30 and is connected to the water tank 30.

[0036] By setting the positioning pin 13 through penetration, the whole device can be positioned on the ground. However, since the vibration of the whole device cannot be completely avoided, when the positioning pin 13 is vertically penetrated, the whole device will vibrate when the drill rod 20 is working. The role of the positioning pin 13 is to provide restriction to prevent the whole device from vibrating to the left and right. While having a certain shockproof effect, it can limit the vibration direction of the whole device. In this way, when the whole device vibrates, it is more likely to vibrate up and down, and the amplitude of this vibration is not high, which can enhance the function of vibration discharge of soil debris in the aforementioned scheme.

[0037] In the whole scheme, the water source inside the water tank 30 is pumped out by the water pump 142 and sprayed out through the nozzle 141. A plurality of water curtain nozzles are integrated inside the nozzle 141. By superimposing the spray angles between the water curtain nozzles, an annular spray state is formed, thereby forming a hemispherical covering state. Since the airflow of the hole drilled by the drill rod 20 is in an upward state, the middle position of the nozzle 141 under this design can be used for the circulation of airflow.

[0038] In the above scheme, the positioning pin 13 is positioned only by a single plug-in connection. This installation method may loosen under high-frequency vibration. In order to limit the axial shaking of the structure and reduce the impact of vibration, please refer to Figures 1 to 11 The positioning pin 13 includes a mounting tube 131 and a drill bit 132, one end of the drill bit 132 is connected to a spline shaft 133, one end of the mounting tube 131 is provided with a spline groove matched with the spline shaft 133, the bottom of the spline groove is provided with an elastic member 134, the other end of the elastic member 134 is fixed to the spline shaft 133, the upper end surface and the lower end surface of the rear frame 12 are provided with nuts 135, the nuts 135 are threadedly fixed on the outside of the mounting tube 131, and the bottom of the water tank 30 is provided with a plurality of positioning pins 2 37 with the same internal structure as the positioning pin 13.

[0039] The spline shaft 133 is used to provide radial rotation restriction for the mounting tube 131 and the drill bit 132, that is, the rotation of the drill bit 132 and the mounting tube 131 is first restricted to ensure that only vertical relative movement can occur between the mounting tube 131 and the drill bit 132 during use, and no other movement state can occur. The entire mounting tube 131 is fixed to the rear frame 12 by the nut 135, and the drill bit 132 and the mounting tube 131 are connected by the elastic member 134. The drill bit 132 can be drilled into the ground to form a stable fixed state. This fixation can ensure a stable connection without shaking, and the setting of the elastic member 134 is The purpose is to ensure that the mounting tube 131 can generate axial vertical movement during the whole process. In this case, if the whole device moves, vertical shaking can be generated due to the limitation of the mounting tube 131, and the setting of the elastic member 134 can ensure the connection while forming a rebound effect. Among them, a damper can be selected for the elastic member 134. The damper can reduce the amplitude of the shaking while retaining the shaking. This amplitude can affect the vibration of the whole device, so that the whole device can generate vibration within a certain range, thereby meeting the requirements of the aforementioned scheme, and reducing the amplitude of the vibration, and having a certain shockproof effect.

[0040] To further improve the power structure of the solution, please refer to Figures 1 to 4 A driving assembly 111 is provided on the upper end surface of the lifting platform 11, a slider 112 is provided on one side of the lifting platform 11, the slider 112 is vertically lifted along the lifting frame 10, a connecting plate 144 is provided on the side of the front frame 14 away from the rear frame 12, and the other end of the connecting plate 144 is fixed to the outer wall of the water tank 30.

[0041] The entire drill rod 20 is driven to rotate by the driving component 111, and the structure of the lifting platform 11 usually adopts a screw track structural design, and the rotation of the screw drives the rotation of the slider 112, and the driving component 111 usually adopts the cooperation between the motor and the gear to realize the rotation of the drill rod 20. In addition, there is also a method of setting the drill rod 20 as a multi-section nested structure and driving the drill rod 20 to rotate by injecting gas into the inside. The drill rod 20 and its corresponding scheme are not improved in this embodiment, and its corresponding scheme does not belong to the protection content of this embodiment, so its specific structure is not explained.

[0042] In order to divide the internal structure of the water tank 30 more specifically, please refer to Figures 1 to 8 The water tank 30 includes a shell 31, a water filter plate 362 is arranged in the middle position inside the shell 31, the water filter plate 362 separates the interior of the water tank 30 to form a liquid storage chamber 32 located below and a material receiving chamber 33 located above, and the slot 36 is connected to the material receiving chamber 33.

[0043] The filtered water is filtered through the water filter plate 362, and the filtered water is stored in the liquid storage chamber 32. The liquid pipe 143 is connected to the liquid storage chamber 32 for water delivery, and the upper material receiving chamber 33 is used to retain soil residue.

[0044] The soil residue is discharged from the receiving chamber 33 through the cooperation between the baffle plate 1 42 and the baffle plate 2 43. In order to further improve the cooperation structure between the baffle plate 1 42 and the baffle plate 2 43, please refer to Figures 1 to 5 Side grooves 361 are provided on both sides of the lower wall of the slot 36, and a receiving drawer 40 with a middle portion passing through is inserted into the slot 36. Positioning plates 411 are provided on both sides of the receiving drawer 40. The positioning plates 411 are inserted into the inside of the side grooves 361 and move back and forth in a straight line in the side grooves 361. Baffle plate 1 42 and baffle plate 2 43 are provided inside the middle portion of the passing groove of the receiving drawer 40.

[0045] The materials are received by the receiving drawer 40. Figure 5 In the state shown, the middle part is hollow and through, so that the debris can accurately fall on the surface of the water filter plate 362 when falling. When the receiving drawer 40 is pulled out, the waste residue can be completely discharged. This is to avoid the presence of large particles causing the entire device to be blocked and facilitate manual operation. Under normal circumstances, part of the soil residue can be discharged to the outside only through vibration without causing dust problems.

[0046] In order to prevent soil debris from being left in the uncovered area between the filter plates 362, please refer to Figures 1 to 4 A side platform 35 is provided between two adjacent water filter plates 362 , and the upper end surface of the side platform 35 is blade-shaped, and the two side edges of the side platform 35 are in contact with the side walls of the receiving drawer 40 .

[0047] With the aid of the blade-shaped side platform 35, when soil debris falls onto the side platform 35, due to the inclined design on both sides thereof, the soil debris mixed with the water source can flow onto the water filter plate 1 362, thereby avoiding the problem of soil debris accumulation.

[0048] In order to further improve the structural features of the receiving drawer 40, please refer to Figures 1 to 8 The receiving bin 40 includes two vertically arranged side panels 41 , a baffle plate 1 42 is connected to the ends of the two side panels 41 located at the slots 36 , and a baffle plate 2 43 is connected to the middle positions of the two side panels 41 .

[0049] Two side panels 41 are used to provide vertical support on both sides, the front side is connected through baffle 1 42, and the middle part is connected through baffle 2 43. In this case, it is only necessary to ensure that baffle 2 43 and baffle 1 42 are tilted toward the outside to achieve the function of allowing soil debris to slide away during vibration.

[0050] In the above solution, the state of the receiving bin 40 is fixed. When the structure is blocked by large particles of gravel, the function of vibrating and discharging may not be realized normally. To solve this problem, please refer to Figures 9 to 12 The receiving drawer 40 includes two vertically arranged side panels 41, baffle 1 42 is connected to the ends of the two side panels 41 located at the slot 36, baffle 1 42 is vertically arranged, baffle 2 43 is connected to the side of the two side panels 41 close to the drill rod 20, and a mounting groove 351 is provided on the side of the side platform 35 close to the receiving drawer 40, and a rotatable gear 352 is provided inside the mounting groove 351, and the upper end surface of the positioning plate 411 has a tooth groove, and the gear 352 is meshed with the tooth groove.

[0051] Different from the aforementioned solution, the baffle 42 is in a vertical state, and the gear 352 is integrated inside the side platform 35, which pushes the positioning plate 411 by rotation, thereby pushing out the entire receiving bin 40. The rotation of the gear 352 can be driven by a motor set inside. It only needs to set the working time of the motor periodically to achieve multiple pushes within a cycle, thereby avoiding the problem of larger particles of gravel blocking the entire receiving bin 40.

[0052] In the above scheme, whether there is the gear 352 and its auxiliary structure, when the entire receiving drawer 40 is retracted, the receiving drawer 40 will squeeze the dust, and this squeezing may cause it to be unable to be retracted normally. To avoid this problem, please refer to Figures 1 to 8 Specifically, the tail ends of the two side plates 41 are connected to the water filter plate 44, the inner wall of the outer shell 31 is provided with an inner cavity 34 that penetrates to the upper end surface, the other end of the inner cavity 34 penetrates to the upper end surface of the water filter plate 1 362, the upper end surface of the inner cavity 34 is inserted with an insert plate 341, the lower end surface of the insert plate 341 is connected to an elastic member 45, the other end of the elastic member 45 is connected to the water filter plate 44, and the other end of the water filter plate 44 is fixed to the two side plates 41.

[0053] The support state is achieved at the tail by setting the water filter plate 2 44, and the water filter plate 2 44 also needs to have a water filtering function. In addition, it is also necessary to ensure that the water filter plate 2 44 can be bent. Usually, a soft plate with small holes on the surface can be used. In this way, when the material receiving drawer 40 is pulled out, the water filter plate 2 44 pulls the elastic member 2 45 to move outward, and has the water filtering function while ensuring the material receiving, thereby further enhancing the water filtering effect. When the water filter plate 2 44 moves inward, since the water filter plate 2 44 is bent at the hinge between the water filter plate 1 362 and the inner cavity 34, when soil residue is here, a certain overturning state will be generated, thereby generating a relative motion state for the soil residue to move toward the baffle plate 2 43, thereby reducing the probability of the soil residue being over-extruded, hardened and blocked.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
