Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine mining, and particularly relates to a drum blasting adjustable-height open-pit coal mine coal mining and stripping machine. Background Art

[0002] Open-pit coal mine coal mining is an important coal mining method. When mining, hard coal seams and rock layers may be encountered. At this time, generally, a stripper is used to break the coal seam, or blasting is carried out through a blasting device (in the case of a relatively thick rock layer or hard coal seam). A coal mining and stripping machine is a device used in open-pit coal mine mining to remove substances such as rocks, soil, and hard coal seams covering the surface of the coal seam.

[0003] Before blasting, generally, holes need to be drilled on the surfaces of the hard coal seam and the rock layer first, and then the blasting device is fixed inside the holes for blasting. In this way, the hard coal seam and the rock layer can be effectively shattered by vibration. However, some hard coal seams and rock layers are relatively high, which brings trouble to drilling. For this reason, those skilled in the art have proposed a drum blasting adjustable-height open-pit coal mine coal mining and stripping machine to solve the problems raised in the background art.

[0029] Embodiment

[0030] Please refer to Figure 1 - Figure 6As shown in the figure, a drum blasting adjustable height open-pit coal mine coal mining and stripping machine includes a walking chassis mechanism 1 (the walking chassis mechanism 1 is a prior art, mentioned in the Chinese invention patent with the authorization announcement number of CN201747367, used to drive the upper mechanical structure to move in any direction), and a control transmission unit 2. When in use, the user can remotely control the walking chassis mechanism 1 to move on the ground through the control transmission system at the construction site console (set near the walking chassis mechanism 1) (it can also be electrically connected to the control transmission unit 2 through a remote control to achieve short-distance control). At the same time, a moving frame 3 is installed above the walking chassis mechanism 1 under the action of the installation unit 6. When in use, the user can adjust the inclination angle of the adjustment frame 4 rotatably installed on the inner wall of the moving frame 3 through the angle adjustment unit 5, so as to drive the two coal mining spiral drums 7 respectively rotatably installed on both sides of the adjustment frame 4 to move, realizing the control of the spatial height of the two coal mining spiral drums 7. Because one end of each of the two coal mining spiral drums 7 is relatively sharp, when in use, the user can control the rotation of the two coal mining spiral drums 7 through the first drive unit 8 (under the action of the first drive unit 8, the two coal mining spiral drums 7 are respectively rotatably installed on both sides of the adjustment frame 4), achieving the purpose of drilling (inserting one of the coal mining spiral drums 7 into the coal seam for drilling, and the coal mined by the drilling will be carried out by the spiral teeth on the surface of the coal mining spiral drum 7);

[0031] The main components of the control transmission unit 2 are: an installation box 21 fixedly installed on the surface of the moving frame 3. At the same time, a controller 22 and a 4G transmission unit 23 electrically connected to the controller 22 are fixedly installed on the inner wall of the installation box 21. The 4G transmission unit 23 can be remotely electrically connected to an external console (such as a remote control and other devices). Also, because the controller 22 is electrically connected to the walking chassis mechanism 1, when the user remotely controls the controller 22 through a remote control and other devices, the remote control of the walking chassis mechanism 1 can be achieved through the controller 22. At the same time, in order to prevent dust from entering the interior of the installation box 21, after the user fits an installation plate 24 on the surface of the installation box 21, several installation bolts 25 are threadedly inserted into the surface of the installation plate 24, so that several installation bolts 25 are all threadedly inserted into the surface of the installation box 21, thereby achieving the purpose of dust-proofing through the installation plate 24;

[0032] The main components of the angle adjustment unit 5 are as follows: mounting protrusions 51 provided on the surface of the moving frame 3. During use, the user remotely controls the telescoping of two first hydraulic rods 52 that are rotatably mounted on the surface of the mounting protrusions 51 through the controller 22, which can drive the movement of the adjustment frame 4 rotatably mounted at the other ends of the two first hydraulic rods 52, thereby achieving control of the tilt angle of the adjustment frame 4. The main components of the mounting unit 6 are as follows: sliding protrusions 62 provided at the bottom of the moving frame 3, and at the same time, driving grooves 61 are formed at the top of the walking chassis mechanism 1. During use, the user remotely controls the telescoping of two second hydraulic rods 63 fixedly mounted on the inner wall of the driving groove 61 through the controller 22, which can drive the sliding protrusions 62 fixedly mounted at the other ends of the two second hydraulic rods 63 to slide on the inner wall of the driving groove 61, thereby achieving the driving of the moving frame 3 above the walking chassis mechanism 1.

[0033] The main components of the first driving unit 8 are as follows: a number of notches 81 formed on the surface of the adjustment frame 4, and at the same time, one end of each of the two coal mining spiral drums 7 is rotatably inserted into the inner walls of two of the notches 81. During use, the user controls the rotation of the output end of the double-headed motor 82 fixedly mounted on the inner wall of the adjustment frame 4 through the controller 22, which can drive the rotation of the two coal mining spiral drums 7 fixedly mounted at both ends of the double-headed motor 82 respectively, further achieving the driving of the coal mining spiral drums 7. It should be noted that: the spiral teeth on the surface of the coal mining spiral drum 7 can cut the coal seam and at the same time transport the coal blocks on the surface of the coal mining spiral drum 7. This is common in coal mining machinery and is a relatively mature existing technology. Its main structure consists of: 1. Drum body: Usually cylindrical, which is the main part of the spiral drum. Its material is generally selected from high-strength and high-toughness steel to withstand the huge pressure and impact force during coal mining. 2. Spiral blade: Installed on the drum body along the axial direction of the drum, which is the key component for coal transportation. Parameters such as the shape and pitch of the spiral blade will affect the coal transportation efficiency and effect. Generally speaking, the pitch of the blade is designed according to factors such as the drum diameter and rotation speed to ensure that the coal can move smoothly along the axial direction of the drum. 3. Picks: Installed in the tooth seat sleeves on the spiral blade for coal breaking. The types of picks include flat picks (knife-shaped picks) and conical picks (pick-shaped picks). Currently, most coal mining machine spiral drums use pick-shaped picks. Pick-shaped picks have the advantages of high tooth body strength, wear resistance, self-rotating edge repair, small cutting angle, and small bending moment, which are beneficial to reducing specific energy consumption and improving cutting efficiency. 4. End plate: Located at both ends of the drum, which plays a role in sealing and supporting, preventing coal from leaking from both ends of the drum and ensuring the structural integrity of the drum. 5. Tooth seat: Used to install picks, fixing the picks on the spiral blade to ensure that the picks can work stably during coal mining.

[0034] By arranging a moving frame 3 above the walking chassis mechanism 1, during use, the user can control the walking chassis mechanism 1 through the control transmission unit 2 to drive the moving frame 3 and the adjustment frame 4 rotatably installed on the inner wall of the moving frame 3 to move, and then adjust the inclination angle of the adjustment frame 4 through the angle adjustment unit 5. By controlling the rotation of the two coal mining spiral drums 7 through the second driving unit 13, the purpose of breaking the coal seam and the rock layer can be achieved. In the case of too thick rock layer, the user can control the sharp end of the coal mining spiral drum 7 to rotate and insert into the coal seam and the rock layer, thus completing the purpose of rapid drilling, facilitating the subsequent blasting operation, and achieving the purpose of dual use of one machine.

[0035] By opening a driving groove 61 above the walking chassis mechanism 1, during use, the user remotely controls the telescopic movement of the two second hydraulic rods 63 both fixedly installed on the inner wall of the driving groove 61 through the controller 22 at the construction site console via the 4G transmission unit 23, which can drive the sliding protrusions 62 (arranged below the moving frame 3) fixedly installed at the other ends of the two second hydraulic rods 63 to slide on the inner wall of the driving groove 61, further realizing the driving of the moving frame 3. That is, when drilling with the coal mining spiral drum 7, the user can drive the moving frame 3 to drive the coal mining spiral drum 7 to move, so as to smoothly insert it into the surface of the hard coal seam or the rock layer.

[0036] As Figure 3 and Figure 4 shown, in some embodiments, it further includes a plurality of supporting rollers 9. The plurality of supporting rollers 9 are respectively arranged on the inner walls of a plurality of notches 81, and two of the supporting rollers 9 are respectively fixedly sleeved on the surfaces of the two coal mining spiral drums 7. Also, because the other two supporting rollers 9 are respectively rotatably inserted into the inner walls of two of the notches 81, when the two coal mining spiral drums 7 rotate, they will drive two of the supporting rollers 9 to rotate, further realizing the driving of the crawler conveyor belt 10 slidably sleeved on the surfaces of the plurality of supporting rollers 9. The surface of the coal mining spiral drum 7 is a spiral tooth, so the cut coal will move to the surface of the crawler conveyor belt 10 and move on the surface of the crawler conveyor belt 10 to realize the transportation function of the coal blocks. Therefore, this device can be used as a coal mining machine.

[0037] As Figure 1 and Figure 2As shown, in some embodiments, an installation groove 11 is provided above the moving frame 3, and a conveyor belt 12 is arranged inside the installation groove 11. During use, the user can control the conveyor belt 12 arranged inside the installation groove 11 to move along itself through the second driving unit 13, thereby driving the falling coal blocks to move, so as to realize the further transportation of the coal blocks and discharge the cut coal blocks at the rear end of the walking chassis mechanism 1. The main components of the second driving unit 13 are: two driving wheels 131 that are both rotatably installed on the inner wall of the installation groove 11. During use, the user remotely controls the output end of the driving motor 132 fixedly installed on the surface of the moving frame 3 to rotate through the controller 22, which can drive one of the driving wheels 131 to rotate, thereby realizing the movement of the conveyor belt 12 sleeved on the surfaces of the two driving wheels 131 along itself.

[0038] The working process of the present invention:

[0039] First, when blasting is required, the user needs to remotely control the two second hydraulic rods 63 to expand and contract through the controller 22, which can drive the sliding protrusion 62 to slide on the inner wall of the driving groove 61, thereby realizing the driving of the moving frame 3 above the walking chassis mechanism 1. Control the two ends of the double-headed motor 82 to rotate, drive the two coal mining spiral drums 7 to rotate, and complete the drilling operation to facilitate the installation of subsequent blasting equipment;

[0040] Secondly, during the above process, the coal blocks generated during the drilling process will be carried out by the coal mining spiral drums 7 with spiral teeth on the surface, and fall on the surfaces of the crawler conveyor belt 10 and the conveyor belt 12 in sequence, and finally be discharged at the tail of the walking chassis mechanism 1.

The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
