Technical Field
[0001] This utility model relates to the field of through-layer drilling, specifically a through-layer drilling machine. Background Technology
[0002] As human technology continues to advance, the items manufactured by humans are becoming increasingly complex. At the same time, the raw materials required for these new items are becoming more diverse, with more and more types of minerals being mined, leading to the development of more and more mines.
[0003] Drilling machines have always played a crucial role in mine drilling and excavation. They can not only drill through soil layers but also detect materials from the drilled holes to determine the quality of minerals. They can also be used to create a series of holes for subsequent overall cutting. However, existing drilling machines suffer from instability during drilling, and the reaction force exerted by the ground on the drill rod can easily push the entire machine up.
[0004] In view of this, in order to overcome the above-mentioned technical problems, this utility model designs a layer-penetrating drilling machine, which solves the above-mentioned technical problems. Utility Model Content
[0005] This utility model provides the following technical solution:
[0006] This utility model provides a drilling machine for drilling through layers, comprising: a vehicle body, a main drill bit, and an auxiliary drill bit;
[0007] A main drill bit is fixedly installed at the center of the vehicle body, and several auxiliary drill bits are arranged around the main drill bit. The main drill bit is used for drilling through layers, and the auxiliary drill bits are used to fix the vehicle body.
[0008] The auxiliary drill bit includes a hollow auxiliary drill rod, an electric push rod is fixedly installed in the inner cavity of the auxiliary drill rod, and multiple blocking rods are rotatably installed on the bottom side wall of the auxiliary drill rod. The middle and upper sections of the blocking rods are hinged to connecting rods, and the connecting rods are hinged to the push rods of the electric push rods.
[0009] The auxiliary drill bits drill downwards at predetermined points. When the auxiliary drill bits reach a certain depth, the electric actuator extends and retracts, pushing the connecting rod to rotate, thereby causing the blocking rod to rotate outwards and open, thus completing the overall fixation of the device. Subsequently, the main drill bit can be used for drilling through layers. Because the blocking rod is open, it uses the auxiliary drill bits to fix the vehicle body, preventing the vehicle body from shifting or lifting during the drilling process.
[0010] Preferably, the auxiliary drill bit further includes an auxiliary housing and a second drive device and a second telescopic device disposed within the auxiliary housing. The upper end of the second telescopic device is fixedly connected to the auxiliary housing, and the lower end is fixedly connected to the second drive device. The second drive device is fixedly connected to the auxiliary drill rod. The second drive device drives the auxiliary drill rod to rotate, and simultaneously pushes the auxiliary drill rod through the second telescopic device to apply pressure to the ground. Applying pressure to the ground allows the drill rod to better complete the drilling work across layers.
[0011] Preferably, the main drill bit includes a main drill rod, a main housing, a first drive device and a first telescopic device disposed within the main housing, the upper end of the first telescopic device being fixedly connected to the main housing and the lower end being fixedly connected to the first drive device, and the first drive device being fixedly connected to the main drill rod.
[0012] The first drive device drives the drill rod to rotate, and at the same time pushes the drill rod through the first telescopic device to pressurize the ground. Pressurizing the ground allows the drill rod to better complete the drilling work through the layers.
[0013] Preferably, movable plates are further provided between the first telescopic device and the first driving device, and between the second telescopic device and the second driving device, respectively, and are slidably connected to the main housing and the sub-housing. The movable plates are used to connect the first telescopic device and the first driving device, as well as the second telescopic device and the second driving device.
[0014] Preferably, the movable plate is provided with multiple sliding grooves, and the main housing and the auxiliary housing are provided with multiple sliding rails opposite to the sliding grooves. Since the sliding grooves and the sliding rails are slidably connected, the main drill rod and the auxiliary drill rod will move vertically downward stably. The sliding grooves and sliding rails can prevent the reaction force exerted by the drill rod on the first drive device or the second drive device from causing the first drive device or the second drive device to rotate.
[0015] Preferably, both the first driving device and the second driving device are electric motors.
[0016] Preferably, both the first and second telescopic devices employ hydraulic rods, wherein the first telescopic device uses three sets of hydraulic rods. By using three sets of hydraulic rods, greater and more stable pressure is applied to the main drill bit.
[0017] Preferably, a handle is fixedly connected to one side of the upper end of the vehicle body. The worker can move the vehicle body by pushing the handle, and when the vehicle body is pushed to the target position, the drilling work can begin.
[0018] Preferably, the lower end of the vehicle body is equipped with several omnidirectional wheels. These wheels allow the vehicle to reach the target location more easily.
[0019] Beneficial effects: The auxiliary drill bits drill downwards at predetermined points. When the auxiliary drill bits reach a certain depth, the electric actuator extends and retracts, pushing the connecting rod to rotate, thereby causing the blocking rod to rotate outwards and open, thus completing the overall fixation of the device. Subsequently, the main drill bit can be used for drilling through layers. Because the blocking rod is open, it uses the auxiliary drill bits to fix the vehicle body, preventing the vehicle body from shifting or lifting during the drilling process.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. To address the problem of vehicle body instability during the operation of a through-layer drilling machine, the following solution is proposed:
[0029] like Figure 1-4 As shown, a layer-penetrating drilling machine includes a vehicle body 1, a main drill bit 2, and an auxiliary drill bit 3;
[0030] A main drill bit 2 is fixedly installed at the center of the vehicle body 1, and several auxiliary drill bits 3 are arranged around the main drill bit 2. The main drill bit 2 is used for drilling through layers, and the auxiliary drill bits 3 are used to fix the vehicle body 1.
[0031] The auxiliary drill bit 3 includes a hollow auxiliary drill rod 31. An electric push rod 311 is fixedly installed in the inner cavity of the auxiliary drill rod 31. A plurality of blocking rods 313 are rotatably installed on the bottom side wall of the auxiliary drill rod 31. The middle and upper sections of the blocking rods 313 are hinged to connecting rods 312. The connecting rods 312 are hinged to the push rods of the electric push rods 311.
[0032] The auxiliary drill bits 3 drill downwards at predetermined points. When the auxiliary drill bits 3 drill to a certain depth, the electric actuator 311 extends and retracts, pushing the connecting rod 312 to rotate, thereby causing the blocking rod 313 to rotate outwards and open, thus completing the overall fixing of the device. Subsequently, the main drill bit 2 can then perform through-layer drilling. Because the blocking rod 313 is open, it uses the auxiliary drill bits 3 to fix the vehicle body 1, preventing the vehicle body 1 from shifting or lifting during the through-layer drilling process.
[0033] like Figure 1-4As shown, the auxiliary drill bit 3 also includes an auxiliary housing 32 and a second drive device 33 and a second telescopic device 34 disposed within the auxiliary housing 32. The upper end of the second telescopic device 34 is fixedly connected to the auxiliary housing 32, and the lower end is fixedly connected to the second drive device 33. The second drive device 33 is fixedly connected to the auxiliary drill rod 31. The second drive device 33 drives the auxiliary drill rod 31 to rotate, and simultaneously pushes the auxiliary drill rod 31 through the second telescopic device 34 to apply pressure to the ground. Applying pressure to the ground allows the drill rod to better complete the drilling work across layers.
[0034] like Figure 1-4 As shown, the main drill bit 2 includes a main drill rod 21, a main housing 22, a first drive device 23 and a first telescopic device 24 disposed in the main housing 22. The upper end of the first telescopic device 24 is fixedly connected to the main housing 22, and the lower end is fixedly connected to the first drive device 23. The first drive device 23 is fixedly connected to the main drill rod 21.
[0035] The first driving device 23 drives the drill rod to rotate, and at the same time pushes the drill rod through the first telescopic device 24 to pressurize the ground. Pressurizing the ground allows the drill rod to better complete the drilling work through the layers.
[0036] like Figure 1-4 As shown, movable plates 4 are respectively provided between the first telescopic device 24 and the first driving device 23, and between the second telescopic device 34 and the second driving device 33, and are slidably connected to the main housing 22 and the secondary housing 32. The movable plates 4 are used to connect the first telescopic device 24 and the first driving device 23, as well as the second telescopic device 34 and the second driving device 33.
[0037] like Figure 1-4 As shown, the movable plate 4 is provided with multiple sliding grooves 41, and the main housing 22 and the auxiliary housing 32 are provided with multiple sliding rails 5 opposite to the sliding grooves 41. Since the sliding grooves 41 and the sliding rails 5 are slidably connected, the main drill rod 21 and the auxiliary drill rod 31 will move vertically downward stably. The sliding grooves 41 and the sliding rails 5 can prevent the reaction force exerted by the drill rod on the first drive device 23 or the second drive device 33 from causing the first drive device 23 or the second drive device 33 to rotate.
[0038] like Figure 1-4 As shown, both the first drive device 23 and the second drive device 33 are electric motors.
[0039] like Figure 1-4 As shown, both the first telescopic device 24 and the second telescopic device 34 employ hydraulic cylinders, wherein the first telescopic device 24 uses three sets of hydraulic rods. By using three sets of hydraulic rods, greater and more stable pressure is applied to the main drill bit 2.
[0040] like Figure 1-4 As shown, a handle 11 is fixedly connected to one side of the upper end of the vehicle body 1. The worker can push the handle 11 to move the vehicle body 1, and when the vehicle body 1 is pushed to the target position, the drilling work can begin.
[0041] like Figure 1-4 As shown, several casters 12 are installed at the lower end of the vehicle body 1. The casters 12 enable the vehicle body 1 to reach the target position more easily.
[0042] Working principle: The auxiliary drill bits 3 drill downwards at predetermined points. When the auxiliary drill bits 3 drill to a certain depth, the electric actuator 311 extends and retracts, pushing the connecting rod 312 to rotate, thereby causing the blocking rod 313 to rotate outwards and open, thus completing the overall fixing of the device. Then, the main drill bit 2 can be used for drilling through layers.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
