Description

Technical Field

[0001] The utility model relates to the technical field of raw material cutting, in particular to a cutting device for raw materials in earthwork engineering construction. Background Art

[0002] In earthwork engineering construction, slabs are needed. Since the lengths of slabs required at different positions are different, the slabs need to be cut on the construction site. Currently, when cutting slabs, a cutting device is required to cut the slabs into the required sizes to ensure the quality and specifications in earthwork engineering construction.

[0003] Currently, when a cutting device cuts a slab, the slab usually needs to be limited and fixed. When the existing cutting device limits and fixes the slab, most of them are fixed manually, and the outer side and the top of the slab cannot be limited and fixed at the same time. As a result, the slab is prone to shaking under the action of cutting force or other external forces during cutting. It is difficult for the slab in a shaking state to maintain stability during cutting, resulting in the deviation of the cutting route and cutting errors, thereby reducing the construction efficiency. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings of the prior art, the utility model provides a cutting device for raw materials in earthwork engineering construction, which can effectively solve the problem of shaking of slab raw materials during cutting in the prior art.

[0005] To achieve the above object, the utility model is realized through the following technical solutions:

[0006] The utility model provides a cutting device for raw materials in earthwork engineering construction, including a cutting frame. Both sides of the cutting frame are fixedly installed with telescopic columns. A telescopic component is arranged on one of the telescopic columns. The telescopic ends of the two telescopic columns are jointly fixedly connected with an electric slide rail. A cutting component is arranged on the electric slide rail. Two pressing components are symmetrically arranged at the bottom of the electric slide rail. A roller conveying structure is arranged inside the cutting frame, and two pressing components are arranged inside the roller conveying structure;

[0007] The pressing component includes an elastic telescopic piece, and a pressing wheel is installed at the lower end of the elastic telescopic piece;

[0008] The pressing component includes a bidirectional lead screw rotatably installed inside the cutting frame. The end of the bidirectional lead screw is coaxially fixedly connected with an extension rod. The extension rod movably penetrates through the inside of the cutting frame. A pair of pressing blocks are reversely threaded and sleeved on the outer wall of the bidirectional lead screw. A limiting plate is slidably penetrated between the two pressing blocks. Both ends of the limiting plate are fixedly installed inside the cutting frame;

[0009] The two extension rods are drivingly connected through a belt drive assembly, and a servo motor for driving one of the bidirectional lead screws to rotate is fixedly connected to the outer surface of the cutting frame.

[0010] Further, the cutting assembly includes a slide rail block slidably connected to the electric slide rail. A first motor is fixedly installed at the bottom of the slide rail block, and a cutting blade is fixedly installed at the output end of the first motor.

[0011] Further, the telescopic assembly includes a toothed plate fixedly installed on the outer wall of one side of the telescopic end of the telescopic column. The toothed plate meshes with a gear, and a self-locking motor for driving the gear to rotate is fixedly connected to the outer surface of the cutting frame.

[0012] Further, a pair of baffles are symmetrically and fixedly installed on the upper surface of the cutting frame. The two baffles are respectively located on both sides of the first motor, and a collection box is arranged between the two baffles.

[0023] The following further describes the present invention with reference to the embodiments.

[0024] Embodiment: Refer to Figures 1 to 3 .

[0025] An earthwork engineering construction raw material cutting device, including a cutting frame 1. An earthwork engineering construction raw material cutting device, including a cutting frame 1, telescopic columns 2 are fixedly installed on both sides of the cutting frame 1. A telescopic assembly is provided on one of the telescopic columns 2, and the telescopic ends of the two telescopic columns 2 are commonly fixedly connected to an electric slide rail 3. A cutting assembly is provided on the electric slide rail 3, and two pressing assemblies are symmetrically provided at the bottom of the electric slide rail 3. A roller conveying structure 101 is arranged inside the cutting frame 1, and two extrusion assemblies are arranged inside the roller conveying structure 101;

[0026] The pressing assembly includes an elastic telescopic member 6, and a pressing wheel 601 is installed at the lower end of the elastic telescopic member 6;

[0027] The extrusion assembly includes a bidirectional screw rod 8 rotatably mounted inside the cutting frame 1, the end of the bidirectional screw rod 8 is coaxially fixedly connected with an extension rod 13, the extension rod 13 movably penetrates the inside of the cutting frame 1, and the outer wall of the bidirectional screw rod 8 is reversely threaded with a pair of extrusion blocks 9, the two extrusion blocks 9 slide together and penetrate the limit plate 902, and both ends of the limit plate 902 are fixedly mounted on the inside of the cutting frame 1;

[0028] The two extension rods 13 are connected to each other through a belt transmission assembly 14 , and a servo motor 10 for driving one of the bidirectional screw rods 8 to rotate is fixedly connected to the outer surface of the cutting frame 1 .

[0029] The slate material is placed on the cutting frame 1, and the slate material is conveyed by the roller conveying structure 101. When the slate material passes through the extrusion assembly, one of the bidirectional screws 8 is driven by the servo motor 10 to rotate, and the extrusion block 9 threaded on the outer wall of the bidirectional screw 8 moves inward. The limit plate 902 sliding through the two extrusion blocks 9 plays a limiting role when the extrusion block 9 moves. When the extrusion blocks 9 on both sides squeeze the two sides of the slate material, they play a clamping and limiting role. When the stone material is transported to the required cutting position, the electric slide rail 3 fixed at the telescopic end is driven to extend downward by the telescopic assembly. The pressing assembly fixed at the bottom of the electric slide rail 3 first contacts the upper surface of the stone material, and can be pressed on the upper surface of the stone material according to the elastic expansion of the pressing assembly. Then the electric slide rail 3 can drive the cutting assembly to move in the guide rail of the electric slide rail 3 through the slide rail block 4. When the cutting assembly cuts the slate material, the mutual cooperation between the extrusion assembly and the pressing assembly prevents the slate material from shifting during the cutting process.

[0030] Specifically, refer to Figure 1 The cutting assembly includes a slide block 4 slidably connected to the electric slide rail 3, a first motor 5 is fixedly installed at the bottom of the slide block 4, and a cutting blade 501 is fixedly installed at the output end of the first motor 5. The slide block 4 slidably connected to the electric slide rail 3 is moved in the width direction of the electric slide rail 3 to drive the first motor 5 at the bottom of the slide block 4, and the first motor 5 is driven. Then, the driving end of the first motor 5 drives the cutting blade 501 to rotate to cut the stone.

[0031] Specifically, refer to Figure 1The telescopic assembly includes a toothed plate 201 fixedly mounted on the outer wall of one side of the telescopic end of the telescopic column 2, the toothed plate 201 is meshed with a gear 12, and the outer surface of the cutting frame 1 is fixedly connected to a self-locking motor 11 that drives the gear 12 to rotate. The self-locking motor 11 is started, and the gear 12 fixedly connected to the self-locking motor 11 is meshed with the toothed plate 201, and the toothed plate 201 fixed on one side of the telescopic end of the telescopic column 2 performs telescopic movement according to the forward and reverse rotation of the driving end.

[0032] Specifically, referring to the cutting frame 1 and the telescopic column 2, a pair of baffles 7 are symmetrically fixedly installed on the upper surface of the cutting frame 1, the two baffles 7 are respectively located on both sides of the first motor 5, and a collecting box 15 is arranged between the two baffles 7, and the collecting box 15 is fixedly installed on the bottom of the cutting frame 1. The baffles 7 fixedly installed on both sides of the first motor 5 play a protective role in the process of cutting stone raw materials, preventing the splashing of stone slab debris from the cutting of stone raw materials, and passing through the collecting box 15 fixedly installed between the two baffles 7, the debris is collected into the collecting box 15 through the baffle 7.

[0033] Specifically, refer to Figure 1 The two extrusion components are respectively located on both sides of the cutting component. When cutting the stone raw materials, the two extrusion components clamp and limit the stone raw materials.

[0034] Specifically, refer to Figure 3 The opposite surfaces of the two extrusion blocks 9 are movably embedded with extrusion wheels 901. When the stone is extruded and limited, the extrusion wheels 901 contact the two sides of the stone slab raw material, which plays an anti-displacement role. When the stone slab raw material moves through the roller conveying structure 101, it will not limit the movement of the stone raw material.

[0035] The working principle of the utility model is as follows:

[0036] The stone slab raw materials to be cut are placed on the roller conveying structure 101 for conveying. When the conveyed stone slab raw materials pass through the extrusion assembly, the staff drives the Tiida servo motor 10 and drives one of the bidirectional screws 8 to rotate through the servo motor 10, and then the end of the bidirectional screw 8 is coaxially fixedly connected to the extension rod 13, and the two extension rods 13 are rotated through the belt transmission assembly 14. The extension rod 13 moves through the inner side of the cutting frame 1 and the extrusion block 9 threadedly sleeved on the outer wall of the bidirectional screw 8 moves inward. When the extrusion blocks 9 on both sides move with the two sides of the stone slab raw materials, the extrusion wheels 901 embedded in the two extrusion blocks 9 that are movable toward each other come into contact with the two sides of the stone slab, which plays a role of clamping and limiting the two sides of the stone raw materials.

[0037] When the stone raw material is conveyed to the position where it needs to be cut, the self-locking motor 11 is started and driven to rotate forward, driving the gear 12 fixedly connected to the driving end of the self-locking motor 11. The toothed plate 201 fixed to one side of the telescopic end of the telescopic column 2 meshes with the gear 12, and then makes a telescopic movement according to the forward rotation of the driving end, driving the electric slide rails 3 fixed to the telescopic ends of the two telescopic columns 2 to move towards the stone raw material. The pressing assembly fixed to the bottom of the electric slide rail 3 first contacts the upper surface of the stone raw material. According to the elastic expansion and contraction of the elastic expansion member 6, the pressing wheel 601 fixed to the lower end of the pressing wheel 601 can press on the upper surface of the stone raw material. The pressing wheels 601 on the two elastic expansion members 6 simultaneously contact and press the upper surface of the stone raw material. By starting the first motor 5, at this time, the slide block 4 moving left and right on the electric slide rail 3 drives the first motor 5 fixed to the lower end of the slide block 4, and the cutting blade 501 fixed to the driving end of the first motor 5 rotates to perform cutting operations. When cutting the slate raw material, the cooperation between the contact of the pressing wheel 901 with both sides of the slate raw material and the pressing of the pressing wheel 601 on the lower surface of the slate raw material prevents the slate raw material from shifting during the cutting process. At the same time, when cutting the slate raw material, the baffles 7 fixedly installed on both sides of the first motor 5 play a protective role during the cutting of the stone raw material, preventing the flying of the slate scraps cut from the stone raw material, and through the collection box 15 fixedly installed between the two baffles 7, the scraps are collected into the collection box 15 through the baffles 7.

[0038] After the cutting of the slate raw material is completed, the staff starts the reverse rotation of the self-locking motor 11 to drive the toothed plate 201 meshing with the gear 12, and drives the telescopic column 2 to rise and separate from the stone raw material through the toothed plate 201. The pressing wheels 901 on both sides of the slate raw material will not affect the conveyance of the slate raw material. At this time, the cut slate raw material can continue to be conveyed through the roller conveying structure 101.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
