The utility model relates to floor processing technical field, concretely discloses a floor processing grooving device, including support station, be provided with horizontal moving mechanism on support station, be provided with the spacing fixing mechanism that carries out the spacing to floor on horizontal moving mechanism, and set up the grooving mechanism that carries out the front and back slot cutting to the floor that removes on support station, the spacing fixing mechanism includes the support frame that sets up on horizontal moving mechanism, and the left and right screw lead screw and guide pillar are horizontally parallel and are provided on the support frame, and the moving frame is oppositely installed on the left and right screw lead screw and guide pillar. Through horizontal moving mechanism spacing fixing mechanism and the setting of grooving mechanism on support station, make the floor and backstop align and place on spacing fixing mechanism, and the grooving mechanism adjusts the height position of floor grooving and adapts, and the whole spacing fixing mechanism is pushed through the grooving mechanism through horizontal moving mechanism, and the floor front and back two sides are grooved simultaneously, improve the efficiency of floor grooving.

This utility model relates to the field of composite flooring processing technology, specifically a grooving device for composite flooring processing, including an operating table and a moving block. The operating table has symmetrically bolted cylinders providing power, and the power output end of the cylinders is bolted to a top frame. An adjustment component for moving the moving block is installed inside the top frame, and a drive motor providing power is bolted to the inside of the moving block. When grooving the composite flooring, a fan on the top filter box of the top frame, controlled by a PLC controller, generates suction within the filter box. A branch pipe installed on one side of the filter box extends to the inside of the moving block, drawing air from the grooving area of ​​the composite flooring. This draws dust generated during grooving into the filter box on one side of the branch pipe, facilitating the cleaning and collection of sawdust and dust generated during composite flooring grooving and improving the grooving efficiency of the composite flooring.

The application discloses a deep coal seam slotted fracturing permeability improvement device, which comprises a fracturing agent supply device, a flow guide pipe arranged in a drill hole formed in a deep coal seam and connected with an input end of the fracturing agent supply device, and a fracturing slotted device arranged on end portions of adjacent flow guide pipes and used for connecting the adjacent flow guide pipes.
