[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions.

[0028] like Figure 1-8The concrete slab cutting device shown includes a shell 1, which includes two parts: a protective part 110 and a supporting part 120. The supporting part 120 is fixedly connected to the bottom of the protective part 110. The protective part 110 is longitudinal, and the supporting part 120 is transverse. The protective part 110 has a hollow structure, usually in the vertical direction, and the supporting part 120 is correspondingly in the horizontal direction. The main part of the protective part 110 is a disc-shaped cover body 111. In fact, the cover body 111 is not a complete disc, and the side of the disc has a flat cross-section.
[0029] The main part of the supporting part 120 is a flat skateboard 121. The lower surface of the skateboard 121 is smooth and has a very low friction coefficient. Two sets of shaft frames 123 are fixedly connected at both ends of the skateboard 121. The shaft frames 123 are perpendicular to the plane where the skateboard 121 is located. A rubber-coated wheel 5 is rotatably connected between each set of shaft frames 123 through a wheel axle 124. The rubber-coated wheel 5 has the advantages of both support and vibration reduction. The specific structure of the rubber-coated wheel 5 includes a wheel hub 501 rotatably connected to the wheel axle 124. The wheel hub 501 is usually made of hard plastic. The outer side of the wheel hub 501 is wrapped with a wear-resistant sleeve 502, and the wear-resistant sleeve 502 is supported by a soft and elastic rubber material, serving as a buffer component between the wheel hub 501 and the concrete slab to avoid direct hard contact between the wheel hub 501 and the surface of the concrete slab. The outer side of the cover body 111 is also fixedly connected to a handle 112. The handle 112 is usually provided with two handles 112, which are close to the top of the cover body 111, so as to facilitate pushing and lifting the entire cutting device or changing the bottom inclination angle of the cutting device.
[0030] A blade body 4 is movably connected inside the shell 1. The main part of the blade body 4 is a saw disk 401, which is the main component for realizing concrete slab cutting. The edge of the blade body 4 extends to the outside of the shell 1 for direct contact with the concrete slab. A through groove 122 is provided on the bottom surface of the slide plate 121. The through groove 122 is connected to the inside of the cover body 111, so that the saw disk 401 can pass through and the working edge for cutting can be extended to the outside of the shell 1.
[0031] A driving mechanism 3 is fixedly connected to the outside of the shell 1, and the driving mechanism 3 is used to drive the cutter body 4 to rotate. The driving mechanism 3 is fixedly connected to one side of the cover body 111. The driving mechanism 3 includes a linked motor and a reducer. The reducer is driven by the motor. The end face of the saw disk 401 has a coaxial end shaft 402. There are two end shafts 402, which are respectively located at the two end faces of the saw disk 401. The cover body 111 is provided with a main shaft hole 113. A bearing structure is usually provided in the main shaft hole 113, which is used to cooperate with the end shaft 402 to form a rotating pair, thereby limiting the freedom of movement of the entire cutter body 4. One of the end shafts 402 passes through the main shaft hole 113 and is fixedly connected to the output end of the reducer, thereby obtaining the rotational power of the driving mechanism 3.
[0032] A dust removal mechanism 2 is also fixedly connected to the outside of the shell 1. The dust removal mechanism 2 is suitable for communicating with the interior of the shell 1 to extract and collect dust inside the shell 1. In fact, the dust removal mechanism 2 is fixedly connected to the other side of the cover body 111. A pair of convection holes 114 are provided on the side wall of the cover body 111, one for exhausting air and the other for exhausting air, which are respectively connected to the input end and the output end of the dust removal mechanism 2. The dust removal mechanism 2 includes a dust collecting box 201 fixedly connected to the shell 1. The side of the dust collecting box 201 facing away from the cover body 111 is open. An air pump 203 is fixedly connected to the outer side of the dust collecting box 201 to drive air to generate airflow. Two air pumps 203 are usually arranged, one is mainly responsible for exhausting air, and the other is mainly responsible for inflation. The power of the two air pumps 203 is equivalent, so that the power is shared, which can effectively reduce the heating efficiency of a single air pump 203. The two air pumps 203 are connected to the two convection holes 114 through the guide pipe 204 respectively, so as to form a channel for air circulation.
[0033] A detachable dust collecting plate 202 is provided in the dust collecting box 201, which is composed of a plurality of filtering adsorption nets and only allows air to pass through the holes, while solid particles such as dust will be intercepted. The end face of the dust collecting plate 202 facing away from the dust collecting box 201 is fixedly connected with a sealing plate 205, and the sealing plate 205 is tightly fitted with the end face where the open mouth of the dust collecting box 201 is located, so that the dust collecting box 201 has good air tightness, and the outer side surface of the sealing plate 205 is fixedly connected with a handle 206, which is convenient for pulling the dust collecting plate 202 out of the dust collecting box 201 through the sealing plate 205 for cleaning or replacement.
[0034] Working principle: When in use, place the bottom surface of the skateboard 121 against the surface of the concrete slab to be cut, let the edge of the saw disc 401 contact the concrete slab, and start the air pump 203 on the driving mechanism 3 and the dust removal mechanism 2 at the same time. The saw disc 401 generates a large amount of dust when cutting the concrete slab, which will be brought into the dust collecting box 201 by the annular airflow formed by the air pump 203, and intercepted and adsorbed by the dust collecting plate 202. This can effectively reduce the dust generated during the cutting process and reduce the harm to the environment and human body during the work process. Hold the handle 112 on the top of the cutting device, and under the rolling support of the rubber-coated wheel 5, the entire cutting device can be translated on the concrete slab to achieve continuous cutting operations.
