Description

Technical Field

[0001] This utility model relates to the field of cement road cutting devices, and in particular to a cement road cutting device. Background Technology

[0002] Road surfaces expand and contract with seasonal and diurnal temperature variations. Timely joint cutting after road construction can reduce the impact of base layer cracks on the road surface. Joint cutting is a crucial step in the construction and maintenance of cement roads. It prevents irregular cracks from forming due to thermal expansion and contraction, thus improving road lifespan and driving safety.

[0003] However, existing cement road cutting devices do not have precise control over the cutting depth, which can easily lead to cutting too deep or too shallow, affecting the cutting effect and causing the cut lines to be crooked, thus affecting the aesthetics. Therefore, we propose a cement road cutting device to solve the problems mentioned above. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a cement road cutting device, which can solve the technical problems of existing cement road cutting devices, such as insufficient control of cutting depth, which easily leads to cutting too deep or too shallow, affecting the cutting effect, and the cutting lines are easily crooked, affecting the aesthetics.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slit cutting machine, wherein a cutting blade is rotatably mounted on the inner end of the slit cutting machine, a mounting frame is fixedly mounted on the outer end of the slit cutting machine, a connector is fixedly mounted on the inner end of the mounting frame, a hydraulic rod is fixedly mounted on the lower end of the connector, a roller is fixedly mounted on the lower end of the hydraulic rod, a mounting plate is fixedly mounted on the outer end of the slit cutting machine, a screw is threadedly connected to the inner end of the mounting plate, a ball is fixedly mounted on the lower end of the screw, a linear rail is provided on the outer side of the ball, a groove is opened on the inner side of the linear rail, and a card is fixedly mounted on the outer end of the linear rail.

[0006] As a preferred embodiment of this utility model, a baffle is integrally installed on the upper end of the linear rail, and the baffle is disposed on the upper side of the slide groove.

[0007] As a preferred embodiment of this utility model, a push rod is fixedly installed at the upper end of the cutting machine, and a caster wheel is fixedly installed at the lower end of the cutting machine.

[0008] As a preferred embodiment of this utility model, the outer end of the screw is threaded with a fastening nut, and the outer wall of the fastening nut is tightly fitted with the mounting plate.

[0009] In a preferred embodiment of this invention, the hydraulic rod and roller are positioned on the front side of the cutting blade.

[0010] In a preferred embodiment of this invention, the ball slides inside the groove and is disposed between two sets of baffles.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. It is equipped with a mounting frame, connectors, hydraulic rods and rollers. When the length of the hydraulic rod changes, it drives the height of the mounting frame and connectors at the front end of the cutting machine. The rollers contact the road surface. By controlling the extension and retraction of the hydraulic rod, the depth of the cutting blade into the cement road can be precisely adjusted, which can meet the requirements of different cutting depths of cement roads.

[0013] 2. Equipped with a screw, ball bearings, and a linear guide, the linear guide is placed vertically above the road to be cut, with the card fitting against the edge of the road. The screw is then rotated downwards, allowing the ball bearings to roll inside the linear guide, ensuring the straightness of the cut and improving its aesthetics. Attached Figure Description

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides a cement road cutting device.

[0022] The inner end of the cutting machine 1 is rotatably equipped with a cutting blade 6, the outer end of the cutting machine 1 is fixedly equipped with a mounting frame 2, the inner end of the mounting frame 2 is fixedly equipped with a connector 3, the lower end of the connector 3 is fixedly equipped with a hydraulic rod 4, the lower end of the hydraulic rod 4 is fixedly equipped with a roller 5, the upper end of the cutting machine 1 is fixedly equipped with a push rod 7, and the lower end of the cutting machine 1 is fixedly equipped with a caster wheel 8. The hydraulic rod 4 and the roller 5 are located on the front side of the cutting blade 6. By controlling the extension and retraction of the hydraulic rod 4, the cutting depth of the cutting blade 6 into the cement road can be precisely adjusted, which can meet the requirements of different cement road cutting depths.

[0023] A mounting plate 9 is fixedly installed on the outer end of the slit cutting machine 1. A screw 10 is threadedly connected to the inner end of the mounting plate 9. A ball bearing 11 is fixedly installed on the lower end of the screw 10. A linear rail 13 is provided on the outer side of the ball bearing 11. A groove 15 is formed on the inner side of the linear rail 13. A clip 16 is fixedly installed on the outer end of the linear rail 13. A baffle 14 is integrally installed on the upper end of the linear rail 13 and is located on the upper side of the groove 15. A fastening nut 12 is threadedly connected to the outer end of the screw 10, and the outer wall of the fastening nut 12 fits tightly against the mounting plate 9. The ball bearing 11 slides on the inner side of the groove 15. The ball bearing 11 is positioned between the two sets of baffles 14 to ensure the straightness of the cut and improve the aesthetics of the cut.

[0024] Specific working principle:

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this cement road cutting device, if a straight cut is required, place the straight rail 13 flat on the road surface, ensuring the card 16 is flush with the edge of the road surface, so that the straight rail 13 is in a straight position. Then, push the cutting machine 1 to one side of the straight rail 13, align the ball bearing 11 with the upper side of the straight rail 13, loosen the fastening nut 12, and then rotate the screw 10 downwards to make the ball bearing 11 contact the inner wall of the groove 15. Then, tighten the fastening nut 12 again to limit the cutting depth. Adjust the cutting depth according to the required cutting depth. The height of the blade 6 is such that when the hydraulic rod 4 extends, the front of the cutting machine 1 is lifted, and the cutting depth of the cutting blade 6 becomes shallower. When the hydraulic rod 4 shortens, the cutting machine 1 drives the cutting blade 6 to move downward, and the cutting depth increases. Then, the operator holds the push rod 7 with both hands and pushes the cutting machine 1. The universal wheel 8 rotates, and the ball bearing 11 rolls inside the straight rail 13 to achieve straight cutting. The above completes a series of operations of the cement road cutting device. The contents not described in detail in this instruction belong to the prior art known to those skilled in the art.
