Description

Technical Field

[0001] The invention belongs to the technical field of blasting tools, and in particular relates to an automatic blasthole plugging machine. Background Art

[0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in the air, water, soil and rock media or objects to achieve the desired purpose. When explosive bags or charges explode in soil and rock media or structures, the soil and rock media or structures will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork projects and the demolition of buildings. Medium and deep hole blasting is generally used in open-pit and underground mining and underground excavation. The blasting methods are strip explosive bags, multiple explosive bags, and delayed blasting. In the actual excavation process, it is necessary to use drilling equipment to drill a certain number of blastholes with a certain arrangement in advance according to the actual situation of the blasting site for loading explosives. After loading the explosives, it is necessary to use sand and other blasthole filling materials to plug the blastholes to achieve blasting.

[0003] At present, a blasting hole filling trolley with announcement number CN107650960B on the market includes a storage box, a nylon rope and a baffle; a total of four moving wheels are fixedly and symmetrically installed on both sides of the bottom of the base; a pull ring is fixedly arranged on the other side of the baffle; a nylon rope is passed through the pull ring; a No. 2 rope loop is also fixedly arranged on one side of the top of the base; and a No. 1 rope loop is fixedly arranged on one side of the push-pull handle. The setting of the baffle is conducive to the convenience of use. The baffle is a left-right movable structure, and a circular through-hole structure is arranged on one side of the baffle. When the rope handle is pulled by hand, the nylon rope will move to the right, thereby driving the baffle on the side of the pull ring to move to the right. At this time, the circular through-hole will overlap with the bottom of the discharge pipe, and the sand in the storage box will leak downwards, completing the filling operation. When the rope handle is released, the spring will pull the spring pull plate back to the left, thereby pulling back the baffle on the side of the spring pull plate, which is convenient to use.

[0004] However, there are some problems: 1. The device cannot adjust the angle and orientation of the discharge pipe, and it is difficult to fill some angled holes. 2. The stones after crushing by the device are screened, and some large stones still fall into the blastholes before being crushed. Summary of the invention

[0005] The invention provides an automatic blasthole plugging machine, which is used to solve the problem that the angle and orientation of a discharge pipe cannot be adjusted and some holes with angles are difficult to plug.

[0006] This solution provides an automatic blasthole plugging machine, comprising:

[0007] Frame;

[0008] Storage hopper: used to place stones;

[0009] Wheel: The wheel is rotatably connected to the frame;

[0010] Power source: used to provide power for wheel rotation, frame movement and storage hopper rotation;

[0011] Discharge pipe: the discharge pipe is connected to the storage hopper and is provided with a valve;

[0012] Also includes:

[0013] Guide groove oil cylinder: used to control the valve switch, the guide groove oil cylinder is fixedly connected to the frame;

[0014] Tipping bucket oil cylinder: the cylinder body of the tipping bucket oil cylinder is hingedly connected to the vehicle frame, and the piston rod of the tipping bucket oil cylinder is hingedly connected to the storage hopper;

[0015] Rotating disk: the rotating disk is fixedly connected to the storage hopper, and the rotating disk is rotatably connected to the frame.

[0016] The principle of this scheme is that when the blast hole needs to be filled, the operator controls the frame to move to the vicinity of the blast hole, and then the operator controls the rotating disk and the bucket cylinder to align the discharge pipe with the blast hole, and then the operator controls the valve of the discharge pipe to open to fill the blast hole.

[0017] The beneficial effect of this solution is that the device can drive the storage hopper through the rotating disk to drive the discharge pipe to rotate, thereby achieving the effect of adjusting the orientation. At the same time, the device adjusts the frame position through the tipping cylinder to adjust the angle of the discharge pipe, and can fill some angled holes.

[0018] Furthermore, it also includes a crushing mechanism, which includes a crushing wheel, a main shaft and a motor, the shaft of the motor is fixedly connected to the main shaft, the crushing wheel is fixedly connected to the main shaft, and the crushing wheel is located inside the discharge pipe.

[0019] When the operator wants to fill the hole, the operator opens the valve and starts the motor at the same time, causing the stone to fall from the storage hopper to the discharge pipe. At this time, the motor drives the main shaft to rotate, and the main shaft drives the crushing wheel to rotate. The crushing wheel crushes the stone to prevent some large pieces of stone from being unbroken, causing large pieces of stone to fill the blasthole and cause harm to personnel during blasting.

[0020] Furthermore, it also includes a tinkering mechanism, which includes a tinkering rod, a connecting ring and a travel mechanism. The tinkering rod is slidably connected to the connecting ring, the connecting ring is fixedly connected to the main shaft, and the tinkering rod is provided with a travel rod, which cooperates with the travel mechanism.

[0021] When the blasthole is filled, there are often holes, and the filling is not dense, so a tampering stick is needed to tamper with it. Sometimes when there is rainwater in the blasthole, a wooden stick is also needed to tamper with the drainage. When the device is filled, the motor will drive the main shaft to rotate, and the main shaft will drive the connecting ring to rotate together. Since the connecting ring is at a certain distance from the main shaft, the connecting ring rotation path is a circle instead of self-rotation. The connecting ring drives the tampering stick to rotate. At this time, the stroke rod will run on the stroke mechanism, so that the tampering stick moves up and down while doing circular motion, repeatedly tampering with the blasthole. At the same time, the tampering stick rotates up and down to tamper with each position of the blasthole. The existing method is to find a wooden stick of the same size as the blasthole to tamper with it, and because the blastholes are of different sizes, the appropriate wooden stick will be replaced every time, which is very troublesome. The mechanism tampered with the blasthole comprehensively by rotating up and down.

[0022] Furthermore, the travel mechanism is a wavy one-way guide rail, the one-way guide rail is fixedly connected to the discharge pipe, and the travel rod is slidably connected to the one-way guide rail.

[0023] The device uses a one-way rail that goes up and down. When the tampering rod rotates, the travel rod moves on the one-way rail. The one-way rail that goes up and down makes the travel rod move up and down, thereby driving the tampering rod to move up and down while doing circular motion. The mechanism uses the rotation effect of the motor to realize the reciprocating tampering of the tampering rod around the gun hole.

[0024] Furthermore, the travel mechanism is a wavy spiral guide rail, the spiral guide rail is fixedly connected to the discharge pipe, and the travel rod is slidably connected to the spiral guide rail.

[0025] When filling, the filling hole will gradually become shallower with the filling. As the stone is filled, the tampering rod should be lifted up and reciprocated at a certain speed to prevent the wooden stick from being inserted too deep into the blasthole, causing damage to the tampering rod. The threaded wave groove of the spiral guide rail can make the tampering rod move up and down while moving in a circular motion and gradually increase the height. By setting the thread, the lifting height of the tampering rod is consistent with the filling height of the blasthole.

[0026] Furthermore, it also includes a screen, which is rotatably connected to the main shaft, fixedly connected to the tampering rod, and matched with the crushing wheel. The screen is located below the crushing wheel. When the crushing wheel crushes the stone, the screen will screen and leave the missed large stones on the screen. The crushing wheel will crush the stones on the screen. The screen can effectively prevent large stones from falling into the blasthole. At the same time, the screen will reciprocate up and down with the tampering rod, which can shake off the stones blocking the screen and prevent the screen from being blocked.

[0027] Furthermore, the vehicle also includes a hopper door plug cylinder for opening the storage hopper, wherein the hopper door plug cylinder is fixedly connected to the vehicle frame. When the storage hopper needs to be charged, the operator can control the hopper door plug cylinder to open the plug door for charging.

[0028] Furthermore, a felt is provided at the one-way guide rail to prevent stones from entering. The felt can prevent stones from getting stuck on the one-way guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Basically as attached Figure 1 , Figure 2 As shown:

[0036] The present invention provides an automatic blasthole plugging machine, including a vehicle body, a crushing mechanism and a tamping mechanism. The vehicle body includes a storage hopper 1, wheels 2, an operating room 3, a discharge pipe 4, a bucket tipping cylinder 18, a hopper door cylinder 16 and a guide trough cylinder 19: a vehicle frame for bearing weight and providing power; a storage hopper 1 for placing stones, and a bucket capacity 17 of the storage hopper 1 is 6m 3 -8m 3; Wheel 2: Wheel 2 is rotatably connected to the frame; Discharge pipe 4: Discharge pipe 4 is connected to the storage hopper 1, and a valve is provided on the discharge pipe 4; Also includes a guide groove cylinder 19 for controlling the valve switch: The guide groove cylinder 19 is fixedly connected to the frame; Tipping bucket cylinder 18: The cylinder body of the tipping bucket cylinder 18 is hinged to the frame, and the piston rod of the tipping bucket cylinder 18 is hinged to the storage hopper 1; Rotating plate: The rotating plate is fixedly connected to the storage hopper 1, and the rotating plate is rotatably connected to the frame. The hopper door cylinder 16 is fixedly connected to the frame. When it is necessary to add material to the storage hopper 1, the operator can control the hopper door cylinder 16 to open the door for adding material. The operating room 3 is fixedly connected to the frame.

[0037] As attached Figure 3 , Figure 4 As shown:

[0038] The present solution also has a crushing mechanism, which includes a crushing wheel 6 , a main shaft 5 and a motor, wherein the motor is fixed to the housing of the discharge pipe 4 , the shaft of the motor is fixedly connected to the main shaft 5 , the crushing wheel 6 is fixedly connected to the main shaft 5 , and the crushing wheel 6 is located inside the discharge pipe 4 .

[0039] When the operator wants to fill the hole, the operator opens the valve and starts the motor at the same time, so that the stone falls from the storage hopper 1 to the discharge pipe 4. At this time, the motor drives the main shaft 5 to rotate, and the main shaft 5 drives the crushing wheel 6 to rotate. The crushing wheel 6 crushes the stone to prevent some large pieces of stone from not being crushed, causing large pieces of stone to fill the blasthole, which will cause harm to personnel during blasting.

[0040] It also includes a tinkering mechanism, which includes a tinkering rod 12, a connecting ring 11 and a travel mechanism. The travel mechanism is a wavy one-way guide rail 7, and also includes a sliding rod 13. The tinkering rod 12 is fixedly connected to the sliding rod 13, and the sliding rod 13 is slidably connected to the connecting ring 11. The tinkering rod 12 is driven to slide by the sliding rod 13, so that the tinkering rod 12 slides more smoothly. The connecting ring 11 is fixedly connected to the main shaft 5. The tinkering rod 12 is provided with a travel rod 9. The travel rod 9 is located in the one-way guide rail 7, and the diameter of the travel rod 9 is matched with the track gap of the one-way guide rail 7. The one-way guide rail 7 is fixedly connected to the discharge pipe 4, and the travel rod 9 is slidably connected to the one-way guide rail 7.

[0041] When the blasthole is filled, there will be holes in many cases, and the filling is not dense. Sometimes when there is rainwater in the blasthole, wooden sticks are also needed to squeeze and drain. When the device is filled, the motor will drive the main shaft 5 to rotate, and the main shaft 5 drives the connecting ring 11 to rotate together. Since the connecting ring 11 is at a certain distance from the main shaft 5, the connecting ring 11 rotation path is a circle instead of self-rotation, and the connecting ring 11 drives the tampering rod 12 to rotate. At this time, the travel rod 9 will run on the one-way guide rail 7 that goes up and down, so that the tampering rod 12 moves up and down while moving in a circular motion, and repeatedly tampering with the blasthole. At the same time, the tampering rod 12 rotates up and down to tamper, so that each position of the blasthole can be tampered. The existing method is to find a wooden stick of the same size as the blasthole to tamper, and because the blastholes are of different sizes, the appropriate wooden stick will be replaced every time, which is very troublesome, and the mechanism tampered with the blasthole comprehensively by rotating up and down.

[0042] The screen 10 is also included. The screen 10 is rotatably connected to the main shaft 5. The screen 10 is fixedly connected to the tampering rod 12. The screen 10 is located below the crushing wheel 6. When the tampering rod 12 is reciprocating, the screen 10 also moves up and down. When the screen 10 moves to the top, it is closest to the crushing wheel 6, so that the large stones on the screen 10 can be crushed by the crushing wheel 6. The screen 10 is located below the crushing wheel 6. After the crushing wheel 6 crushes the stones, the screen 10 will screen and leave the missed large stones on the screen 10. The crushing wheel 6 will crush the stones on the screen 10. The screen 10 can effectively prevent large stones from falling into the blasthole. At the same time, the screen 10 will reciprocate up and down with the tampering rod 12, and the stones that block the screen 10 can be shaken off to prevent the screen 10 from being blocked.

[0043] The one-way guide rail 7 is provided with a felt that prevents stones from entering. The felt can prevent stones from being blocked on the one-way guide rail 7.

[0044] The principle of this scheme is that when the blast hole needs to be filled, the operator controls the frame to move and comes near the blast hole, then the operator controls the rotating disk and the bucket cylinder 18 to make the discharge pipe 4 align with the blast hole, and then the operator controls the valve of the discharge pipe 4 to open to fill the blast hole.

[0045] At this time, the stone will pass through the discharge pipe 4, and the motor will drive the main shaft 5 to rotate, and the main shaft 5 will drive the crushing wheel 6 to rotate, and the crushing wheel 6 will crush the stone. At the same time, the motor will drive the tampering rod 12 to rotate, and the travel rod 9 will run on the one-way guide rail 7, so that the tampering rod 12 will move up and down while moving in a circular motion, repeatedly tampering with the blasthole. At the same time, the tampering rod 12 rotates up and down to tamper with each position of the blasthole.

[0046] At the same time, when the tampering rod 12 is reciprocating, the screen 10 also moves up and down. When the screen 10 moves to the top, it is closest to the crushing wheel 6, so that the large stones on the screen 10 can be crushed by the crushing wheel 6. The screen 10 is located below the crushing wheel 6. When the crushing wheel 6 crushes the stones, the screen 10 will screen and leave the missed large stones on the screen 10. The crushing wheel 6 will crush the stones on the screen 10.

[0047] The intended effects of this solution are: 1. The device can adjust the angle and orientation of the discharge pipe 4, and can fill some angled holes. 2. It prevents some large pieces of stone from not being broken, causing large pieces of stone to fill the blast hole, which will cause harm to personnel during blasting. 3. The existing method is to find a wooden stick of the same size as the blast hole to fiddle with it. Since the blast holes are of different sizes, the appropriate wooden stick must be replaced every time, which is very troublesome. The mechanism fiddles with the blast hole comprehensively by rotating up and down. 4. The screen 10 can effectively prevent large pieces of stone from falling into the blast hole. At the same time, the screen 10 will do up and down reciprocating motion with the fiddle stick 12, which can shake off the stone blocking the screen 10 and prevent the screen 10 from being blocked.

[0048] As attached Figure 5 As shown:

[0049] Embodiment 2:

[0050] The difference between this embodiment and the first embodiment is that the travel mechanism is a wave-shaped spiral guide rail 15, the spiral guide rail 15 is fixedly connected to the discharge pipe, the travel rod is slidably connected to the spiral guide rail 15, and the rest remains unchanged.

[0051] The guide rail on the spiral guide rail 15 is a spirally ascending wavy guide rail, so that the travel rod 9 gradually increases in height while performing a circular motion and moving up and down reciprocatingly.

[0052] When filling, the filling hole will gradually become shallower with the filling. As the stone is filled, the tampering rod 12 should be lifted up and reciprocated at a certain speed to prevent the wooden stick from being inserted into the blasthole instead of tampering with the stone. The threaded wave-shaped groove of the threaded stroke ring 15 can make the tampering rod 12 gradually increase in height while reciprocating up and down. The thread is set to make the lifting height of the tampering rod 12 consistent with the filling height of the blasthole. When the tampering rod 12 is doing reciprocating motion, the screen 10 also moves up and down. When the screen 10 moves to the top with the threaded wave-shaped groove, it is closest to the crushing wheel 6, so that the large stones on the screen 10 can be crushed by the crushing wheel 6.

[0053] When the operator fills the blastholes with the same depth, a fixed amount is set for filling, and the fixed amount allows the threaded travel ring 15 to complete a circle, just enough to make the tampering rod 12 reach the top. Every time it reaches the blasthole, the valve is opened, and the valve is a flow rate valve, which automatically closes the valve through a delay device. This solution reduces the operator's steps of checking whether the blasthole is filled, and realizes automatic filling.

[0054] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
