slotter

Abstract

The invention discloses a groover which comprises a shell and a motor. A movable cavity with an open bottom is formed in the middle of the shell, a sawblade clamping head is arranged in the movable cavity, and a bevel gear B matched with a bevel gear A is arranged at the other end of a rotary shaft. A reflecting layer and foamed aluminum are sequentially arranged on the inner wall of the movable cavity from top to bottom, and the distance L between the highest point of reflecting protrusions and the outer wall of the movable cavity is gradually increased in the direction from the open end of the movable cavity to a through hole. The sawblade clamping head comprises a nut, clamping blocks and movable blocks, a clearance is reserved between every two adjacent clamping blocks, and the movable blocks can move freely in annular grooves. The reflection efficiency of chippings at the position is the highest, so that the chippings generated nearby the through hole are fast rebounded to the bottom of the movable cavity, and finally the chippings are discharged out of the open end of the movable cavity. Noise generated by cutting is lowered to the minimum, the chippings generated by cutting can be fast discharged out, and grooving efficiency is improved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a slotter. 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
