Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a stone crushing device for water conservancy engineering. Background Technology

[0002] Water conservancy projects are mainly used to regulate and control water resources in nature, eliminate hidden dangers, and benefit human life. In the construction of water conservancy projects, the location must first be excavated before construction can begin. During the excavation in the mountain, rocks of different sizes will be encountered. When encountering larger rocks, they need to be crushed before construction can continue. Therefore, water conservancy engineering rock crushing equipment is needed to remove obstacles in the excavation process.

[0003] Because crushing equipment for water conservancy projects needs to crush stones from top to bottom, and the size and position of the stones vary during the excavation process, when using portable crushing equipment, the spacing between the drill bits is fixed. When crushing larger stones, it is necessary to move the crushing equipment to crush the stones completely, resulting in low crushing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a stone crushing device for water conservancy projects, which can change the distance between drill bits to adapt to crushing work of stones of different sizes, thereby improving crushing efficiency.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a stone crushing device for water conservancy projects, comprising a frame, an inclined handrail fixedly mounted on the frame, a plurality of movable wheels rotatably connected to the lower end of the frame, a stone crushing component slidably connected inside the frame, and a lifting component for driving the stone crushing component to rise and fall inside the frame. The stone crushing component includes a movable frame slidably connected to the frame in a vertical direction, a plurality of drill bits mounted on the movable frame, and a first motor for driving the drill bits to rotate. The output end of the first motor is fixedly connected to the drill bits. An adjustment component for changing the spacing between the drill bits is provided inside the movable frame.

[0006] By adopting the above technical solution, the vehicle frame is moved above the rocks that need to be crushed. The spacing between the drill bits is changed by adjusting the components according to the size of the rocks to be crushed, thereby adapting to the crushing requirements of rocks of different sizes. Then, the rock crushing component is controlled by the lifting component to descend and contact the rocks, thus completing the rock crushing process.

[0007] A further configuration of the present invention is as follows: the adjustment assembly includes a support frame fixedly connected to a movable frame, a drive rod rotatably connected to the support frame, the drive rod having symmetrically arranged threads of the same pitch but opposite directions, a sliding plate symmetrically threadedly connected to the drive rod, a guide rod fixedly connected to the support frame, the guide rod being arranged parallel to the drive rod, the sliding plate being slidably connected to the guide rod, a second motor fixedly connected to the end of the drive rod, the second motor being fixedly connected to the support frame, and a drill bit slidably connected to the sliding plate.

[0008] By adopting the above technical solution, the adjustment component controls the rotation of the drive rod via the second motor, thereby adjusting the distance between the two sliding plates threaded onto the drive rod, thus changing the distance between the drill bits located on the two sliding plates. The guide rod provides better guidance and support for the movement of the sliding plates.

[0009] A further configuration of the present invention includes: a guide rail fixedly mounted on the sliding plate; the guide rail being vertically mounted on the drive rod; sliders slidably connected to both ends of the guide rail; a fixing block fixedly connected to each slider; the fixing block being fixedly connected to a first motor; a limit rod rotatably connected to the sliding plate; the limit rod being parallel to the guide rail; symmetrical arc-shaped grooves being formed at both ends of the limit rod; the upright projection plane of the arc-shaped groove being an arc; the two endpoints of the arc having a certain horizontal distance in the horizontal direction; a limit block embedded in the arc-shaped groove being mounted on the slider; and a drive assembly being mounted on the support frame; the drive assembly being used to control the two limit rods to rotate synchronously in opposite directions.

[0010] By adopting the above technical solution, the two limit rods are controlled to rotate synchronously in opposite directions by the drive component. Since the limit rod is provided with an arc-shaped slide groove, the slider will move along with the rotation of the arc-shaped slide groove when the arc-shaped slide groove rotates. Due to the design of the guide rod, the two drill bits located on the same sliding plate will move away from or closer to each other, thereby changing the distance between the drill bits located on the same sliding plate.

[0011] A further configuration of the present invention is as follows: the driving assembly includes a first pulley fixedly connected to the end of the limiting rod, the first pulley being rotatably connected to the sliding plate, a second pulley and a third pulley symmetrically arranged on the support frame, the second pulley and the third pulley being rotatably connected to the support frame, a synchronous belt being sleeved on the two first pulleys, the second pulley and the third pulley, the synchronous belt sleeved on the first pulley and the second pulley being "S" shaped, and a third motor being fixedly connected to one of the third pulleys, the third motor being fixedly mounted on the support frame.

[0012] By adopting the above technical solution, when the sliding plate moves, since the synchronous belt between the first pulley and the second pulley is "S" shaped, the synchronous belt can still be stably mounted on the first pulley, the second pulley and the third pulley. Under the drive of the third motor, the first pulley rotates in the same direction, thereby realizing the rotation of the two limit rods in the same direction, and thus realizing the movement of the two drill bits located on the same sliding plate away from or close to each other, changing the distance between them.

[0013] A further feature of the present invention is that the two limiting rods are symmetrically arranged along the direction of the vertical guide rod.

[0014] By adopting the above technical solution, when the two first pulleys rotate synchronously, the two limit rods rotate synchronously. At this time, the drill bits set on one of the sliding plates move closer or further away from each other, and the drill bits on the other sliding plate also move closer or further away from each other, proceeding synchronously.

[0015] A further provision of the present invention includes: a water spraying assembly located within the movable frame, the water spraying assembly situated on one side of the crushing stone assembly, the water spraying assembly comprising a support fixedly mounted on the movable frame, a water tank mounted on the support base, a piston slidably connected vertically within the water tank, a fourth motor fixedly mounted on the support frame, a fourth pulley fixedly connected to the output end of the fourth motor, a rotating rod rotatably connected horizontally within the movable frame, the rotating rod rotatably connected to the movable frame, a fifth pulley fixedly connected to the rotating rod, a first belt sleeved between the fourth pulley and the fifth pulley, a cam fixedly connected to the rotating rod, the cam contacting the end of the piston furthest from the water tank, a water pipe fixedly connected to the water tank, a nozzle fixedly connected to the end of the water pipe furthest from the water tank, the nozzle rotatably connected to the support base, the spraying direction of the nozzle facing the crushing stone assembly, and a control assembly for driving the nozzle to reciprocate.

[0016] By adopting the above technical solution, in the water spray assembly, the fourth motor controls the rotation of the rotating rod, which in turn controls the rotation of the cam fixedly connected to the rotating rod, thereby controlling the piston located in the water tank to move up and down reciprocally, so as to pump the water in the water tank into the nozzle through the water pipe to realize the water spraying operation, avoiding the generation of large amounts of dust during the crushing of stones, which could cause physical harm to the operators.

[0017] A further configuration of the present invention is as follows: the control assembly includes a rocking rod fixedly connected to the nozzle, the rocking rod being rotatably connected to a support base, a first transmission rod being rotatably connected to the center of the rocking rod, a second transmission rod being fixedly connected to the end of the first transmission rod away from the rocking rod, a rotating shaft being fixedly connected to the end of the second transmission rod away from the first transmission rod, a sixth pulley being fixedly connected to the end of the rotating shaft away from the second transmission rod, a seventh pulley being fixedly connected to the rotating rod, and a second belt being sleeved between the seventh pulley and the sixth pulley.

[0018] By adopting the above technical solution, the fourth motor drives the rotating rod to rotate, thereby controlling the seventh pulley to drive the sixth pulley to rotate, thereby controlling the rotation of the shaft. The second transmission rod and the first transmission rod control the swaying rod to reciprocate on the support seat, and finally control the nozzle to sway and spray water towards the crushing component, thereby increasing the contact area with the dust generated during crushing and further preventing the dust from being raised.

[0019] A further embodiment of the present invention is that the lifting assembly includes a lifting cylinder fixedly mounted on the vehicle frame, the output end of the lifting cylinder being fixedly connected to the movable frame, vertical limiting members being provided on both sides of the movable frame, and a limiting groove being provided on the vehicle frame for the limiting members to be embedded.

[0020] By adopting the above technical solution, after the drill bit adjusts its spacing under the control of the adjustment component, the lifting cylinder controls the movable frame to descend, so that the drill bit comes into contact with the rock. The first motor drives the drill bit to rotate, thereby breaking the rock.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention changes the spacing between drill bits by designing an adjustment component, thereby changing the overall area of ​​the drill bits according to the size of different stones when crushing them. This facilitates the one-time crushing of large stones while also allowing for concentrated crushing of smaller stones, effectively improving the work efficiency of crushing in water conservancy projects.

[0023] 2. In the adjustment component of this invention, the distance between the sliding plates is controlled by the second motor, thereby controlling the spacing between the drill bits located on the two sliding plates; through the design of the first pulley, the second pulley, the third pulley and the synchronous belt, when the position of the sliding plate changes, the third motor can still control the rotation of the limit rod, so that when the sliding plate is in any position, the spacing between the two drill bits located on the same sliding plate can be changed by controlling the limit rod.

[0024] 3. In this invention, the water spray assembly controls the movement of the piston in the water tank and the reciprocating motion of the nozzle through a fourth motor, which effectively increases the coverage area of ​​the water vapor sprayed from the nozzle and can prevent workers from inhaling dust and gas generated by gravel.

[0033] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example: Please refer to Figure 1-6 A stone crushing device for water conservancy projects includes a frame 1, an inclined handrail 2 fixedly mounted on the frame 1, a plurality of movable wheels 3 rotatably connected to the lower end of the frame 1, a stone crushing component 4 slidably connected inside the frame 1, and a lifting component 5 for driving the stone crushing component 4 to rise and fall inside the frame 1. The stone crushing component 4 includes a movable frame 41 slidably connected to the frame 1 in the vertical direction, a plurality of drill bits 42 mounted on the movable frame 41, and a first motor 43 for driving the drill bits 42 to rotate. The output end of the first motor 43 is fixedly connected to the drill bits 42. An adjustment component 44 for changing the spacing between the drill bits 42 is provided inside the movable frame 41.

[0035] In the specific implementation, the frame 1 is moved above the stone to be crushed. The spacing between the drill bits 42 is changed by adjusting the component 44 according to the size of the stone to be crushed, so as to adapt to the crushing requirements of different sizes of stones. Then, the stone crushing component 4 is controlled by the lifting component 5 to descend and contact the stone to complete the stone crushing process.

[0036] Adjustment assembly 44 includes a support frame 4401 fixedly connected to the movable frame 41. A drive rod 4402 is rotatably connected to the support frame 4401. The drive rod 4402 has symmetrically arranged threads of the same pitch but opposite directions. A sliding plate 4403 is symmetrically threaded onto the drive rod 4402. A guide rod 4404 is fixedly connected to the support frame 4401 and is arranged parallel to the drive rod 4402. The sliding plate 4403 is slidably connected to the guide rod 4404. A second motor 4405 is fixedly connected to the end of the drive rod 4402 and is fixedly connected to the support frame 4401. A drill bit 42 is slidably connected to the sliding plate 4403. A guide rail 4406 is fixedly arranged on the sliding plate 4403. A vertical drive rod 4402 is provided. A slider 4407 is slidably connected to both ends of the guide rail 4406. A fixing block 4408 is fixedly connected to the slider 4407. The fixing block 4408 is fixedly connected to the first motor 43. A limit rod 4409 is rotatably connected to the sliding plate 4403. The limit rod 4409 is parallel to the guide rail 4406. Symmetrical arc-shaped grooves 4410 are provided at both ends of the limit rod 4409. The upright projection surface of the arc-shaped groove 4410 is an arc. The two ends of the arc are a certain horizontal distance apart. A limit block embedded in the arc-shaped groove 4410 is provided on the slider 4407. A drive assembly 6 is provided on the support frame 4401. The drive assembly 6 is used to control the two limit rods 4409 to rotate synchronously in opposite directions.

[0037] In the specific implementation, the adjustment component 44 controls the rotation of the drive rod 4402 via the second motor 4405, thereby adjusting the distance between the two sliding plates 4403 threadedly connected to the drive rod 4402, thus changing the distance between the drill bits 42 located on the two sliding plates 4403. The guide rod 4404 provides better guidance and support for the movement of the sliding plates 4403. The drive component 6 controls the two limit rods 4409 to rotate synchronously in opposite directions. Since the limit rods 4409 are provided with arc-shaped grooves 4410, the slider 4407 will move along with the rotation of the arc-shaped grooves 4410 when the arc-shaped grooves 4410 rotate. Due to the design of the guide rod 4404, the two drill bits 42 located on the same sliding plate 4403 will move away from or closer to each other, thereby changing the distance between the drill bits 42 located on the same sliding plate 4403.

[0038] The drive assembly 6 includes a first belt pulley 61 fixedly connected to the end of the limiting rod 4409. The first belt pulley 61 is rotatably connected to the sliding plate 4403. A second belt pulley 62 and a third belt pulley 63 are symmetrically arranged on the support frame 4401. The second belt pulley 62 and the third belt pulley 63 are rotatably connected to the support frame 4401. A synchronous belt 64 is fitted on the two first belt pulleys 61, the second belt pulley 62, and the third belt pulley 63. The synchronous belt 64 fitted on the first belt pulley 61 and the second belt pulley 62 is "S" shaped. A third motor 65 is fixedly connected to one of the third belt pulleys 63. The third motor 65 is fixedly mounted on the support frame 4401.

[0039] In the specific implementation, when the sliding plate 4403 moves, since the synchronous belt 64 between the first belt pulley 78 61 and the second belt pulley 87 62 is in an "S" shape, the synchronous belt 64 can still be stably mounted on the first belt pulley 78 61, the second belt pulley 87 62 and the third belt pulley 63. Under the drive of the third motor 65, the first belt pulley 78 61 rotates in the same direction, thereby realizing the rotation of the two limit rods 4409 in the same direction, and thus realizing the two drill bits 42 located on the same sliding plate 4403 moving away from or closer to each other, changing the distance between them.

[0040] Two limiting rods 4409 are symmetrically arranged along the direction of the vertical guide rod 4404. When the two first belt pulleys 61 rotate synchronously, the two limiting rods 4409 rotate synchronously. At this time, the drill bit 42 set on one of the sliding plates 4403 moves closer or further away from each other, and the drill bit 42 on the other sliding plate 4403 also moves closer or further away from each other, and the operation is synchronized.

[0041] The movable frame 41 is also equipped with a water spraying assembly 7, which is located on one side of the crushed stone assembly 4. The water spraying assembly 7 includes a support base 71 fixedly mounted on the movable frame 41, a water tank 72 mounted on the support base 71, a piston 73 slidably connected vertically inside the water tank 72, a fourth motor 74 fixedly mounted on the support frame 4401, a fourth pulley 75 fixedly connected to the output end of the fourth motor 74, and a rotating rod 76 rotatably connected horizontally inside the movable frame 41. The rotating rod 76 is rotatably connected to the movable frame 41, and a fixed... A fifth pulley 77 is connected, and a first belt 78 is sleeved between the fourth pulley 75 and the fifth pulley 77. A cam 79 is fixedly connected to the rotating rod 76. The cam 79 contacts the end of the piston 73 away from the water tank 72. A water pipe 710 is fixedly connected to the water tank 72. A nozzle 711 is fixedly connected to the end of the water pipe 710 away from the water tank 72. The nozzle 711 is rotatably connected to the support base 71. The water spray direction of the nozzle 711 is towards the stone crushing assembly 4. A control assembly 8 that drives the nozzle 711 to reciprocate is provided on the movable frame 41.

[0042] In the specific implementation, in the water spray assembly 7, the fourth motor 74 controls the rotation of the rotating rod 76, which in turn controls the rotation of the cam 79 fixedly connected to the rotating rod 76, thereby controlling the piston 73 located in the water tank 72 to move up and down reciprocally, thereby pumping the water in the water tank 72 into the nozzle 711 through the water pipe 710 to achieve water spraying, thus avoiding the generation of large amounts of dust during the crushing of stones, which could cause physical harm to the operators.

[0043] The control assembly 8 includes a rocking rod 81 fixedly connected to the nozzle 711. The rocking rod 81 is rotatably connected to the support base 71. A first transmission rod 82 is rotatably connected to the center of the rocking rod 81. A second transmission rod 83 is fixedly connected to the end of the first transmission rod 82 away from the rocking rod 81. A rotating shaft 84 is fixedly connected to the end of the second transmission rod 83 away from the first transmission rod 82. A sixth pulley 85 is fixedly connected to the end of the rotating shaft 84 away from the second transmission rod 83. A seventh pulley 86 is fixedly connected to the rotating rod 76. A second belt 87 is sleeved between the seventh pulley 86 and the sixth pulley 85.

[0044] In the specific implementation, the fourth motor 74 drives the rotating rod 76 to rotate, thereby controlling the seventh pulley 86 to drive the sixth pulley 85 to rotate, thereby controlling the rotating shaft 84 to rotate. Through the second transmission rod 83 and the first transmission rod 82, the shaking rod 81 is controlled to reciprocate on the support seat 71, and finally the nozzle 711 is controlled to shake and spray water towards the crushing component 4, increasing the contact area with the dust generated during crushing and further preventing the dust from being raised.

[0045] The lifting assembly 5 includes a lifting cylinder 51 fixedly mounted on the frame 1. The output end of the lifting cylinder 51 is fixedly connected to the movable frame 41. Vertical limiting members are provided on both sides of the movable frame 41. The frame 1 has a limiting groove for the limiting members to be inserted. When the drill bit 42 adjusts its spacing under the control of the adjusting assembly 44, the lifting cylinder 51 controls the movable frame 41 to descend, so that the drill bit 42 contacts the stone. The first motor 43 drives the drill bit 42 to rotate, thereby breaking the stone.

[0046] The working principle of this invention is as follows: The handrail 2 is manually pushed to move the frame 1 onto the stones to be broken. Then, depending on the size of the stones to be broken, the second motor 4405 controls the drive rod 4402 to rotate, thereby adjusting the distance between the two sliding plates 4403 threaded onto the drive rod 4402. This changes the distance between the drill bits 42 located on the two sliding plates 4403. Driven by the third motor 65, the first belt 78 pulley 61 rotates in the same direction, thus achieving the same-direction rotation of the two limit rods 4409. This causes the two drill bits 42 located on the same sliding plate 4403 to move closer or further apart, changing the distance between them. Subsequently, the lifting cylinder 51 controls the movable frame 41 to descend, allowing the drill bits 42 to move closer or further apart. 2. Upon contact with the stone, the first motor 43 controls the drill bit 42 to rotate and achieve crushing. At the same time, the fourth motor 74 controls the rotating rod 76 to rotate, which in turn controls the cam 79 fixedly connected to the rotating rod 76 to rotate, thereby controlling the piston 73 located in the water tank 72 to move up and down reciprocally, thereby pumping the water in the water tank 72 into the nozzle 711 through the water pipe 710. The fourth motor 74 drives the rotating rod 76 to rotate, thereby controlling the seventh pulley 86 to drive the sixth pulley 85 to rotate, thereby controlling the rotating shaft 84 to rotate. Through the second transmission rod 83 and the first transmission rod 82, the shaking rod 81 is controlled to move back and forth on the support seat 71, and finally the nozzle 711 is controlled to shake and spray water towards the stone crushing assembly 4.
