Low-noise cutting device

Abstract

The invention discloses a low-noise cutting device. The device comprises a shell and a motor, wherein the middle part of the shell is provided with a movable cavity with an open bottom; a saw blade clamping head is arranged in the movable cavity; the other end of the rotating shaft is provided with a bevel gear B which is matched with a bevel gear A; the movable cavity is provided with a through hole which is communicated with the exterior; the inner wall of the movable cavity is provided with a reflecting layer and foamed aluminum from top to bottom in sequence; the reflecting layer is provided with a plurality of connected annular reflecting bumps; distances L from the highest points of the reflecting bumps to the outer wall of the movable cavity increase along the direction from the open end of the movable cavity to the through hole. The reflection efficiency of scraps at the position is the highest, so that the scraps produced close to the through hole are quickly rebounded to the bottom of the movable cavity and finally discharged from the open end of the movable cavity. According to the device, the noise effect produced by cutting is reduced to the minimum, the scraps produced by the cutting are also quickly discharged, and the slot cutting efficiency is improved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a low-noise cutting device. Background technique [0002] The hidden line layout is usually used for cable wiring in oil warehouses, that is, it is necessary to cut out the grooves for embedding line pipes on the wall or on the ground. For grooves with short width and length, manual operation is more convenient, but for grooves with large length and width, manual removal will increase the workload, consume a lot of energy, and the efficiency of groove removal is low; Groove picking also involves cutting both sides of the groove with a marble machine, and then using a hammer and drill to remove the concrete in the middle of the two cutting seams. Only when a large thrust is applied to the marble machine can the cutting be completed. In the process of use, the saw blade often becomes loose and the motor runs idly.

[0002] The hidden line layout is usually used for cable wiring in oil warehouses, that is, it is necessary to cut out the grooves for embedding line pipes on the wall or on the ground. For grooves with short width and length, manual operation is more convenient, but for grooves with large length and width, manual removal will increase the workload, consume a lot of energy, and the efficiency of groove removal is low; Groove picking also involves cutting both sides of the groove with a marble machine, and then using a hammer and drill to remove the concrete in the middle of the two cutting seams. The cutting can only be completed by applying a large thrust to the marble machine. In the process of use, the saw blade is often loose and the motor is idling.

[0003] Under the long-term use of the marble machine, because of the high decibel noise generated during cutting, the staff will have tinnitus after use, which will lead to a decrease in the efficiency of groove cutting and removal
