Description

Technical Field

[0001] The present invention relates to the technical field of concrete precast component cutting, and particularly to a dust-proof cutting device for concrete precast slate components. Background Art

[0002] Concrete blocks are a kind of concrete precast slate components with relatively simple structures in cement concrete precast components and are widely used in construction. According to different materials, concrete blocks can be divided into ordinary concrete blocks, autoclaved aerated concrete blocks, fly ash small hollow blocks, etc. Existing concrete precast slate components refer to slate-shaped components prefabricated with concrete in factories or on construction sites. These components are usually used for building decoration and structural support and have various shapes and sizes to meet different design requirements. Therefore, cutting equipment is needed to perform segmentation processing according to requirements.

[0003] When the existing concrete precast slate component cutting equipment cuts concrete precast slate components, due to the lack of dust-proof function, a large amount of dust will appear during the cutting process, causing air environmental pollution, thus affecting the working environment of processing personnel and endangering the physical health of workers. Summary of the Invention

[0004] The purpose of the present invention is to provide a dust-proof cutting device for concrete precast slate components to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: The dust-proof cutting device for concrete precast slate components includes a slate conveying main body. Above the output end of the slate conveying main body, a slide rail is installed. A slide seat is slidably installed on the slide rail. A hydraulic lifter is installed at the bottom of the slide seat. A driving motor is installed on the hydraulic lifter. A clamping device is installed on the output shaft of the driving motor. A cutting knife is detachably installed on the clamping device. A connecting rod is installed on the slide seat. A dust suction pipe is installed on the connecting rod. A fixing rod is installed on the top of the slide seat. A dust removal tank is installed on the fixing rod. An air extraction pump is installed on the dust removal tank. The input end of the air extraction pump is connected to the dust suction pipe through an air suction pipe, and the output end of the air extraction pump is connected to the bottom of the dust removal tank through an air delivery pipe. Water flow is stored in the dust removal tank, and a ventilation hole is opened at the top of the dust removal tank. When the output end of the slate conveying main body conveys a concrete precast slate component of a set length, the hydraulic lifter is started to control the cutting knife to the height of the concrete precast slate component, and then the driving motor and the slide rail are started, so that the slide seat can drive the cutting knife to cut the slate component. At the same time, the air extraction pump is started, and the dust-containing gas generated by cutting can be conveyed into the dust removal tank through the dust suction pipe, the air suction pipe and the air delivery pipe, facilitating the water flow in the dust removal tank to adsorb the dust and realizing the purification treatment of the gas.

[0006] As a preferred technical solution, a clamping and fixing assembly, a primary dust removal enhancement assembly, and a secondary dust removal enhancement assembly are provided on the main stone slab conveyor body, and the rotation of the cutting knife is used to provide the operating driving force for the primary dust removal enhancement assembly and the secondary dust removal enhancement assembly.

[0007] As a preferred technical solution, the clamping and fixing assembly includes a bottom plate, a guide rail, a moving seat, a rotating motor, an electric lifter, and a clamping member;

[0008] A bottom plate is installed at the bottom of one side of the main stone slab conveyor body close to the sliding seat. A guide rail is installed on the bottom plate. A moving seat is slidably installed on the guide rail. A rotating motor is installed on the moving seat. An electric lifter is installed on the output shaft of the rotating motor. A clamping member is installed on the electric lifter. When a stone slab prefabricated part of a set length is conveyed out from the output end of the main stone slab conveyor body, by starting the guide rail and the electric lifter, the moving seat can drive the clamping member to clamp and fix the conveyed stone slab prefabricated part, so as to ensure the stability of the stone slab prefabricated part during the cutting process. After the cutting is completed, the rotating motor can be started, and the rotating motor can drive the stone slab prefabricated part to be transported and loaded onto the tray through the electric lifter and the clamping member.

[0009] As a preferred technical solution, the primary dust removal enhancement assembly includes a driving gear, a transmission bevel gear, a driven gear, a transmission chain, a driving bevel gear, a transmission column, a rotating shaft, a rotating ring, stirring blades, and a connecting rod;

[0010] A driving gear is installed on the gripper. A transmission bevel gear is rotatably installed on the upper part of one side of the sliding seat close to the dust suction pipe. A driven gear is concentrically installed on the transmission bevel gear. A transmission chain is sleeved on the driven gear and the driving gear. A driving bevel gear is rotatably installed on the top of the sliding seat. The driving bevel gear meshes with the transmission bevel gear. A transmission column is concentrically installed at the upper end of the driving bevel gear. A rotating shaft is rotatably installed at the bottom of the dust removal tank. A rotating ring is installed at the upper end of the rotating shaft. A plurality of stirring blades are installed on the circumferential side wall of the rotating ring. The lower end of the rotating shaft and the upper end of the transmission column are connected by a connecting rod. When the cutting knife rotates, the gripper can drive the driving gear to rotate. Through the chain drive composed of the driving gear, the driven gear, and the transmission chain, the driven gear drives the transmission bevel gear to rotate synchronously. Then, through the gear meshing action composed of the transmission bevel gear and the driving bevel gear, the driving bevel gear can drive the transmission column to rotate. During the rotation of the transmission column, the stirring blades can be driven to rotate at the inner bottom of the dust removal tank through the connecting rod, the rotating shaft, and the rotating ring, which is beneficial to the stirring blades to disperse the bubbles formed by the dust-containing gas entering the bottom of the dust removal tank and can promote the adsorption effect of the water flow on the dust.

[0011] As a preferred technical solution, the secondary dust removal enhancement assembly includes a piston plate, a transmission rod, a sliding hole, a storage hole, a transmission block, an annular slideway, and a transmission shaft;

[0012] A piston plate is slidably installed in the dust removal tank. A transmission rod is concentrically installed at the lower end of the piston plate. A sliding hole is formed in the rotating shaft. The transmission rod penetrates through the sliding hole and is in sliding fit. A receiving hole is formed at the top of the transmission column. The transmission rod is inserted into the receiving hole. A transmission block is installed at the lower end of the transmission rod. An annular slideway is obliquely arranged on the receiving hole. A transmission shaft is installed on the transmission block. The transmission shaft is slidably inserted into the annular slideway. When the transmission column rotates, the transmission column can drive the transmission block to move longitudinally back and forth through the extrusion force on the transmission shaft by the annular slideway during the rotation process. Since the transmission rod can slide in the sliding hole, the transmission block can drive the piston plate to move synchronously back and forth through the transmission rod during the movement process.

[0013] As a preferred technical solution, a seal is installed at the upper port of the sliding hole.

[0014] As a preferred technical solution, the dust removal multi-stage enhancement component further includes a filter tank, a filter membrane, a water delivery pipe, and a water return pipe;

[0015] A filter tank is installed at the top of the dust removal tank. A filter membrane is installed in the filter tank. The bottom of the dust removal tank is connected to the top of the filter tank through a water delivery pipe. The bottom of the filter tank is connected to the top of the dust removal tank through a water return pipe. When the piston plate moves downward, under the extrusion of the piston plate, the purified water flow in the dust removal tank can enter the filter tank through the water delivery pipe, which is convenient for the filter membrane to filter the dust particles in the purified water flow. The filtered water flow can flow back into the dust removal tank through the water return pipe, which can realize the circulating flow of the purified water flow and is beneficial to promoting the purification effect of the purified water flow on the dust-containing gas.

[0016] As a preferred technical solution, a displacement sensor is installed at the bottom of the transmission block. Three water passing holes are circumferentially arranged on the piston plate. A micro servo motor is concentrically installed at the upper end of the piston plate. An electric telescopic rod is installed on the output shaft of the micro servo motor. A connecting plate is installed on the electric telescopic rod. Three baffle plates are circumferentially installed on the connecting plate. The baffle plates have the same shape and size as the water passing holes. The displacement sensor is electrically connected to the micro servo motor and the electric telescopic rod. When the transmission block moves downward, the displacement sensor can control the connecting plate to rotate 60° through the micro servo motor, which is beneficial for the connecting plate to drive the baffle plate to move to the position of the water passing hole. Then, the electric telescopic rod can drive the connecting plate to move downward, which is beneficial for the baffle plate to fit into the water passing hole, facilitating the extrusion of the purified water flow during the downward movement of the piston plate. When the transmission block moves upward, the displacement sensor can control the electric telescopic rod to lift the connecting plate, so that the baffle plate disengages from the water passing hole of the piston plate. Then, by starting the micro servo motor, the micro servo motor can rotate the connecting plate 60° through the connecting plate, enabling the baffle plate to move away from the water passing hole, facilitating the purified water flow to fall back from the upper part of the piston plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When the output end of the slate conveying main body conveys a concrete precast slate piece of a set length, start the hydraulic lifter, control the cutting knife to the height of the concrete precast slate piece, and then start the driving motor and the slide rail, so that the sliding seat can drive the cutting knife to cut the slate piece. At the same time, start the air extraction pump, and the dust-containing gas generated by cutting can be conveyed into the dust removal tank through the dust suction pipe, the air suction pipe and the air delivery pipe, facilitating the adsorption of dust by the water flow in the dust removal tank and realizing the purification treatment of the gas.

[0019] Through the arranged primary dust removal enhancement component of the present application, by using the rotation of the cutting knife, through the tooth chain transmission composed of the driving gear, the driven gear and the transmission chain, and then through the gear meshing action composed of the transmission bevel gear and the driving bevel gear, the transmission column can drive the stirring blade to rotate at the inner bottom of the dust removal tank, which is beneficial to the stirring blade to disperse the bubbles formed by the dust-containing gas entering the bottom of the dust removal tank and can promote the adsorption effect of the water flow on the dust.

[0020] Through the arranged secondary dust removal enhancement component of the present application, by using the rotation of the transmission column, the piston plate can be driven to move longitudinally back and forth through the extrusion force of the annular slideway on the transmission shaft, and the longitudinal circular flow of the purified water flow in the dust removal tank can be realized.

A hydraulic lifter 4 is installed at the bottom of the slide seat 3. A driving motor 5 is installed on the hydraulic lifter 4. A gripper 6 is installed on the output shaft of the driving motor 5. A cutting tool 7 is detachably installed on the gripper 6. A connecting rod 8 is installed on the slide seat 3. A dust suction pipe 9 is installed on the connecting rod 8. A fixed rod 10 is installed at the top of the slide seat 3. A dust removal tank 11 is installed on the fixed rod 10. An air extraction pump 12 is installed on the dust removal tank 11. The input end of the air extraction pump 12 is connected to the dust suction pipe 9 through an air suction pipe 13. The output end of the air extraction pump 12 is connected to the bottom of the dust removal tank 11 through an air delivery pipe 14. Water flow is stored in the dust removal tank 11, and a ventilation hole 15 is opened at the top of the dust removal tank 11. When the main stone slab conveyor 1 outputs a concrete precast stone slab of a set length, the hydraulic lifter 4 is started to control the cutting tool 7 to the height of the concrete precast stone slab. Then, the driving motor 5 and the slide rail 2 are started, so that the slide seat 3 can drive the cutting tool 7 to cut the stone slab. At the same time, the air extraction pump 12 is started, and the dust-containing gas generated by cutting can be conveyed into the dust removal tank 11 through the dust suction pipe 9, the air suction pipe 13 and the air delivery pipe 14, facilitating the water flow in the dust removal tank 11 to adsorb the dust and realizing the purification treatment of the gas.

[0033] A clamping and fixing assembly 16, a primary dust removal enhancement assembly 17 and a secondary dust removal enhancement assembly 18 are arranged on the main stone slab conveyor 1, and the rotation of the cutting tool 7 is used to provide the operating driving force for the primary dust removal enhancement assembly 17 and the secondary dust removal enhancement assembly 18.

[0034] As Figures 1-3 shown, the clamping and fixing assembly 16 includes a bottom plate 1601, a guide rail 1602, a moving seat 1603, a rotating motor 1604, an electric lifter 1605 and a clamping member 1606;

[0035] On the bottom of one side of the slate conveying main body 1 close to the sliding seat 3, a bottom plate 1601 is installed. On the bottom plate 1601, a guide rail 1602 is installed. A moving seat 1603 is slidably installed on the guide rail 1602. A rotating motor 1604 is installed on the moving seat 1603. An electric lifter 1605 is installed on the output shaft of the rotating motor 1604. A clamping member 1606 is installed on the electric lifter 1605. When the slate conveying main body 1 conveys a slate prefabricated part of a set length at the output end, by starting the guide rail 1602 and the electric lifter 1605, the moving seat 1603 can drive the clamping member 1606 to clamp and fix the conveyed slate prefabricated part, so as to ensure the stability of the slate prefabricated part during the cutting process. After the cutting is completed, the rotating motor 1604 can be started, so that the rotating motor 1604 drives the slate prefabricated part to be transported and loaded onto the tray through the electric lifter 1605 and the clamping member 1606.

[0036] As Figures 1-4 and Figures 6-9 As shown, the primary dust removal enhancement component 17 includes a driving gear 1701, a transmission bevel gear 1702, a driven gear 1703, a transmission chain 1704, a driving bevel gear 1705, a transmission column 1706, a rotating shaft 1707, a rotating ring 1708, stirring blades 1709 and a connecting rod 1710;

[0037] A driving gear 1701 is installed on the gripper 6. A transmission bevel gear 1702 is rotatably installed on the upper part of one side of the sliding seat 3 close to the dust suction pipe 9. A driven gear 1703 is concentrically installed on the transmission bevel gear 1702. A transmission chain 1704 is sleeved on the driven gear 1703 and the driving gear 1701. A driving bevel gear 1705 is rotatably installed on the top of the sliding seat 3. The driving bevel gear 1705 meshes with the transmission bevel gear 1702. A transmission column 1706 is concentrically installed at the upper end of the driving bevel gear 1705. A rotating shaft 1707 is rotatably installed at the bottom of the dust removal tank 11. A rotating ring 1708 is installed at the upper end of the rotating shaft 1707. A plurality of stirring blades 1709 are installed on the circumferential side wall of the rotating ring 1708. The lower end of the rotating shaft 1707 is connected to the upper end of the transmission column 1706 through a connecting rod 1710. When the cutting knife 7 rotates, the gripper 6 can drive the driving gear 1701 to rotate. Through the chain drive composed of the driving gear 1701, the driven gear 1703 and the transmission chain 1704, the driven gear 1703 drives the transmission bevel gear 1702 to rotate synchronously. Then, through the gear meshing action composed of the transmission bevel gear 1702 and the driving bevel gear 1705, the driving bevel gear 1705 can drive the transmission column 1706 to rotate. During the rotation of the transmission column 1706, the stirring blades 1709 can be driven to rotate at the inner bottom of the dust removal tank 11 through the connecting rod 1710, the rotating shaft 1707 and the rotating ring 1708, which is beneficial to the stirring blades 1709 to disperse the bubbles formed by the dust-containing gas entering the bottom of the dust removal tank 11, and can promote the adsorption effect of water flow on dust.

[0038] As Figures 1-5 and Figures 8-9 shown, the dust removal multi - stage enhancement component 18 includes a piston plate 1801, a transmission rod 1802, a sliding hole 1803, a receiving hole 1805, a transmission block 1804, an annular slideway 1806, and a transmission shaft 1807;

[0039] A piston plate 1801 is slidably installed in the dust removal tank 11. A transmission rod 1802 is concentrically installed at the lower end of the piston plate 1801. A sliding hole 1803 is provided on the rotating shaft 1707. The transmission rod 1802 passes through the sliding hole 1803 and is in sliding fit. A receiving hole 1805 is provided at the top of the transmission column 1706. The transmission rod 1802 is inserted into the receiving hole 1805. A transmission block 1804 is installed at the lower end of the transmission rod 1802. An annular slideway 1806 is inclined on the receiving hole 1805. A transmission shaft 1807 is installed on the transmission block 1804. The transmission shaft 1807 is slidably inserted into the annular slideway 1806. When the transmission column 1706 rotates, during the rotation process, the transmission column 1706 can drive the transmission block 1804 to perform longitudinal reciprocating movement through the extrusion force on the transmission shaft 1807 by the annular slideway 1806. Since the transmission rod 1802 can slide in the sliding hole 1803, during the movement of the transmission block 1804, the transmission block 1804 can drive the piston plate 1801 to perform synchronous reciprocating movement through the transmission rod 1802.

[0040] A seal is installed at the upper port of the sliding hole 1803.

[0041] The dust removal multi - stage enhancement component 18 further includes a filter tank 1808, a filter membrane 1809, a water delivery pipe 1810, and a water return pipe 1811;

[0042] A filter tank 1808 is installed at the top of the dust removal tank 11. A filter membrane 1809 is installed in the filter tank 1808. The bottom of the dust removal tank 11 is connected to the top of the filter tank 1808 through a water delivery pipe 1810. The bottom of the filter tank 1808 is connected to the top of the dust removal tank 11 through a water return pipe 1811. When the piston plate 1801 moves downward, under the extrusion of the piston plate 1801, the purified water flow in the dust removal tank 11 can enter the filter tank 1808 through the water delivery pipe 1810, which is convenient for the filter membrane 1809 to filter the dust particles in the purified water flow. The filtered water flow can flow back into the dust removal tank 11 through the water return pipe 1811, which can realize the circulating flow of the purified water flow and is beneficial to promoting the purification effect of the purified water flow on the dust - containing gas.

[0043] A displacement sensor 1812 is installed at the bottom of the transmission block 1804. Three water through holes 1817 are arranged in a circumferential array on the piston plate 1801. A micro servo motor 1813 is concentrically installed at the upper end of the piston plate 1801. An electric telescopic rod 1814 is installed on the output shaft of the micro servo motor 1813. A connecting plate 1815 is installed on the electric telescopic rod 1814. Three baffle plates 1816 are installed in a circumferential array on the connecting plate 1815. The baffle plates 1816 are the same in shape and size as the water through holes 1817. The displacement sensor 1812 is electrically connected to the micro servo motor 1813 and the electric telescopic rod 1814. When the transmission block 1804 moves downward, the displacement sensor 1812 can control the connecting plate 1815 to rotate 60° through the micro servo motor 1813, which is beneficial for the connecting plate 1815 to drive the baffle plate 1816 to move to the position of the water through hole 1817. Then, the electric telescopic rod 1814 can drive the connecting plate 1815 to move downward, which is beneficial for the baffle plate 1816 to fit into the water through hole 1817, facilitating the extrusion of the purified water flow during the downward movement of the piston plate 1801. When the transmission block 1804 moves upward, the displacement sensor 1812 can control the electric telescopic rod 1814 to lift the connecting plate 1815, so that the baffle plate 1816 disengages from the water through hole 1817 of the piston plate 1801. Then, by starting the micro servo motor 1813, the micro servo motor 1813 can rotate 60° through the connecting plate 1815, enabling the baffle plate 1816 to move away from the water through hole 1817, facilitating the purified backflow to fall back from the upper part of the piston plate 1801.

[0044] The working principle of the present invention:

[0045] When the output end of the stone slab conveying main body 1 conveys a concrete precast stone slab of a set length, start the hydraulic lifter 4, control the cutting knife 7 to the height of the concrete precast stone slab, and then start the driving motor 5 and the slide rail 2, so that the slide seat 3 can drive the cutting knife 7 to cut the stone slab. At the same time, start the air extraction pump 12, and the dust-containing gas generated by cutting can be conveyed into the dust removal tank 11 through the dust suction pipe 9, the air suction pipe 13 and the air delivery pipe 14, facilitating the water flow in the dust removal tank 11 to adsorb the dust and realizing the purification treatment of the gas.

[0046] When the output end of the stone slab conveying main body 1 conveys a stone slab precast of a set length, the guide rail 1602 and the electric lifter 1605 can be started, so that the moving seat 1603 can drive the clamping member 1606 to clamp and fix the conveyed stone slab precast, thus ensuring the stability of the stone slab precast during cutting. After cutting, the rotary motor 1604 can be started, and the rotary motor 1604 can drive the stone slab precast to be transported and loaded onto the tray through the electric lifter 1605 and the clamping member 1606.

[0047] When the cutting tool 7 rotates, the gripper 6 can drive the driving gear 1701 to rotate. Through the gear chain drive composed of the driving gear 1701, the driven gear 1703 and the transmission chain 1704, the driven gear 1703 drives the transmission bevel gear 1702 to rotate synchronously. Then, through the gear meshing action composed of the transmission bevel gear 1702 and the driving bevel gear 1705, the driving bevel gear 1705 can drive the transmission column 1706 to rotate. During the rotation of the transmission column 1706, it can drive the stirring blade 1709 to rotate at the inner bottom of the dust removal tank 11 through the connecting rod 1710, the rotating shaft 1707 and the rotating ring 1708, which is beneficial to the stirring blade 1709 to disperse the bubbles formed by the dusty gas entering the bottom of the dust removal tank 11 and can promote the adsorption effect of water flow on dust.

[0048] When the transmission column 1706 rotates, during the rotation process, the transmission column 1706 can drive the transmission block 1804 to move longitudinally back and forth through the extrusion force on the transmission shaft 1807 by the annular slideway 1806. Since the transmission rod 1802 can slide in the slide hole 1803, the transmission block 1804 can drive the piston plate 1801 to move synchronously back and forth during the movement. When the transmission block 1804 moves downward, the displacement sensor 1812 can control the connecting plate 1815 to rotate 60° through the micro servo motor 1813, which is beneficial to the connecting plate 1815 driving the baffle 1816 to move to the water passing hole 1817. Then, the electric telescopic rod 1814 can drive the connecting plate 1815 to move downward, which is beneficial to the baffle 1816 fitting into the water passing hole 1817 to facilitate the downward movement of the piston plate 1801. When the piston plate 1801 moves downward, under the extrusion action of the piston plate 1801, the purified water flow in the dust removal tank 11 can enter the filter tank 1808 through the water delivery pipe 1810, which is convenient for the filter membrane 1809 to filter the dust particles in the purified water flow. The filtered water flow can flow back into the dust removal tank 11 through the water return pipe 1811, realizing the circulating flow of the purified water flow, which is beneficial to promoting the purification effect of the purified water flow on the dusty gas. When the transmission block 1804 moves upward, the displacement sensor 1812 can control the electric telescopic rod 1814 to lift the connecting plate 1815, so that the baffle 1816 disengages from the water passing hole 1817 of the piston plate 1801. Then, by starting the micro servo motor 1813, the micro servo motor 1813 can rotate the connecting plate 1815 by 60° through the connecting plate 1815, enabling the baffle 1816 to move away from the water passing hole 1817, facilitating the purified water flow to fall back from the upper part of the piston plate 1801.
