Description

Technical Field

[0001] The utility model relates to the technical field of dust suction cutting machines, in particular to a handheld dust suction cutting machine. Background Art

[0002] In recent years, environmental issues have received more and more attention. As a device used to cut various materials, cutting machines can save manpower and material resources and speed up construction progress, but they will also generate a lot of cutting dust. This dust not only affects the surrounding environment, but also endangers the health of the operator.

[0003] Most of the existing cutting machines are generally connected to a dust suction device, and the two are used together to achieve the effect of dust suction. The existing dust suction device is large, and it is troublesome to carry it when working outside. In addition, the connection between the two is prone to loosening during work, and the dragging and moving of the connecting pipe and the connected dust suction device during the process is troublesome, which reduces the cutting efficiency to a certain extent. When cutting metal objects, the sparks generated by the cutting machine during operation are usually caused by the high temperature generated by the friction between the high-speed rotating cutting wheel and the material. When the spark is directed to a part away from the human body, there is a risk of rebound when the handheld cutting machine is used, and when the spark is directed to one side of the human body, it may burn clothes or skin due to improper operation angle. Therefore, the present application provides a handheld vacuum cutting machine to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a handheld vacuum cutting machine. Through the setting, the guiding mechanism can be solved. Not only can the shape of the interior of the shell be used to quickly collect and process the dust residues generated during cutting to prevent dust and residues from polluting the working environment, but the structural guidance inside the shell can also be used to guide the sparks generated by metal cutting to effectively prevent the sparks from burning the skin or objects.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A handheld vacuum cutting machine comprises a cutting machine body, a cutting blade is arranged on one side of the cutting machine body, a driving motor is arranged on the other side of the cutting machine body, a connecting line is fixedly connected to the side of the motor away from the cutting blade, and a guide mechanism is used to guide the direction of sparks generated by cutting metal, and the guide mechanism is connected to the cutting machine body.

[0007] Optionally, the guide mechanism includes a shell installed on the cutting machine body, a grip piece is fixedly connected to the top of the cutting machine body, a placement groove is provided on the top of the shell, a baffle is provided in the cavity of the shell, a connecting piece is fixedly connected to the bottom of the grip piece, a brush block is fixedly connected to the bottom of the connecting piece, a movable groove is provided on the top of the shell, and an entrance is provided on the shell near the direction of the cutting piece in the cutting machine body.

[0008] Optionally, the cross-section of the gripping piece is corrugated, the outer wall edge of the gripping piece is arc-shaped, and the exterior of the gripping piece is rough.

[0013] Optionally, a second guide piece is fixedly connected to one side of the bottom of the shell, and a first guide piece is fixedly connected to the other side of the bottom of the shell, and the cross-sections of the second guide piece and the first guide piece are both arc-shaped.

[0014] Optionally, the top shape of the shell is adapted to the shape formed by naturally clenching the palm, and the corrugated shape of the gripping piece is adapted to the shape formed by naturally clenching the fingers.

[0015] Optionally, a sealing plate is provided at the bottom of one side of the shell close to the cutting blade direction in the cutting machine body.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a guiding mechanism, not only can the shape of the interior of the shell be used to quickly collect and process the dust and residue generated during cutting to prevent dust and residue from polluting the working environment, but the structural guidance inside the shell can also be used to guide the sparks generated by metal cutting, effectively preventing the sparks from burning the skin or objects, and it will not cause the cutting machine to rebound and cause accidents.

[0018] By providing a grip piece in the guide mechanism, it is convenient for the fingers to hold the grip piece and cooperate with the fingers to hold one side of the shell, making the device more convenient to hold and use.

[0019] By providing a baffle in the guide mechanism, the airflow can be easily guided and dust and residue can be blocked so that the dust and residue remain in the shell, effectively preventing the residue from polluting the environment and entering the human mouth and nose. The baffle is vertical to prevent dust and residue from clogging the filter holes on it, and the structure further makes the use of the guide mechanism more convenient.

[0020] By arranging a connecting piece and a brush block in the guide mechanism, the shaking generated during the cutting process can be utilized in conjunction with the deformation of the gripping piece, so that the connecting piece can drive the brush block to move, thereby continuously cleaning the filter holes on the baffle plate. The gripping piece can be pressed to cause the connecting piece to drive the brush block to move significantly, thereby more thoroughly cleaning the filter holes on the baffle plate. The structure effectively prevents the baffle plate from being blocked during use, thereby enabling the guide mechanism to be used continuously and efficiently.

[0021] To sum up, through the coordinated use of various structures in the guiding mechanism, not only can the dust generated during the cutting production be collected quickly, the force generated by the rotation of the cutting blade of the cutting machine body can be used to push the dust residue into the shell from the entrance, and the dust residue can be retained and collected in the cavity of the shell through the filtering of the baffle, so that the air flows out from the bottom of the shell, and the metal can be cut again to guide the sparks generated by the cutting, so that the sparks originally directed toward the human body are guided toward the ground to prevent the sparks from burning the human body or clothing. The structure is simple, the production cost is low, and the structure is safe when used. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The working principle of the technical solution provided by the utility model is as follows: when in use, first assemble the components on the cutting machine body 1 into one body, then use screws and nuts to fix the shell 2 on one side of the cutting machine body 1, then connect the cutting machine body 1 to the power supply, then align the base of the hand with the top of the shell 2, and let the fingers pass through the placement groove 5 and wrap around the grip 3, so that the hand can hold the shell 2 quickly and stably, then start the cutting blade on the cutting machine body 1 and rotate it clockwise, so that the generated dust and sparks are directed to one side of the person, and the dust and sparks generated during cutting are affected by the high-speed rotation of the cutting blade on the cutting machine body 1, and enter the cavity of the shell 2 from the entrance 12, and the second guide piece 11 assists in guiding the entry of sparks and dust. After entering the cavity of the shell 2, the dust and sparks continue to move to the side away from the cutting machine body 1 until they reach the baffle 6, and the baffle 6 blocks the dust, so that the dust stays in the cavity of the shell 2, and the sparks pass through the baffle 6 The sparks that have passed through the baffle plate 6 are guided by the first guide plate 10 and are guided out from the bottom opening of the shell 2, so that the sparks are sprayed to the ground and the side away from the human body. During use, the gripping piece 3 and the supporting piece 4 are affected by the cutting vibration, so that they can be shock-absorbing and buffered, and at the same time, they can drive the connecting piece 7 and the brush block 8 to move, so that the brush block 8 scrapes one side of the baffle plate 6. The deformation amplitude of the gripping piece 3 can control the scraping range of the baffle plate 6 by the brush block 8. The brush block 8 receives the thrust of the connecting piece 7 toward the baffle plate 6. The brush block 8 is always in close contact with the baffle plate 6 during use, so that the baffle plate 6 is scraped and cleaned more comprehensively and thoroughly. When the dust in the cavity of the shell 2 is collected to a certain extent, the cutting machine body 1 is closed, and the sealing plate 13 is opened, so that the dust and residue collected inside can be quickly guided out and collected. The structure of the device is simple and it is convenient and quick to use.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention.
