A propulsion mechanism is provided on the front side of the upper surface of the equipment platform 1, and a limiting mechanism is provided on the upper surface of the equipment platform 1. Two symmetrically distributed polishing mechanisms are provided on the upper side of the limiting mechanism. The polishing mechanism includes two square frames 31, and a sanding plate 32 is provided inside the square frame 31. A rotating shaft 33 is fixedly connected to one end of the sanding plate 32, and the rotating shaft 33 is rotatably connected to the square frame 31. Bearing seats 35 are fixedly connected to both ends of the bottom surface of the sanding plate 32, and polishing rollers 36 are installed between the bearing seats 35.

[0024] The frame 31 keeps the angle of the sanding plate 32 adjustable through the rotating shaft 33. The sanding plate 32 is used to install the bearing seat 35. The bearing seat 35 is used to install the polishing roller 36. The polishing roller 36 is used to polish the plate.

[0025] The polishing mechanism further includes two vertical plates 34 , which are respectively fixedly connected to the outer sides of the frame 31 . A first hydraulic cylinder 37 is hinged in the middle of the vertical plates 34 , and the bottom end of the first hydraulic cylinder 37 is hinged to the outer side of the top surface of the sanding plate 32 .

[0026] The vertical plate 34 is used to connect the spacing adjustment mechanism and the frame 31. The first hydraulic cylinder 37 controls the angle of the sanding plate 32 by telescopic extension to achieve polishing of inclined surfaces with different angles.

[0027] The spacing adjustment mechanism includes a slide column 42 , both ends of which are fixedly connected to the top of the vertical plate 2 , a second hydraulic cylinder 41 is fixedly connected to the middle of the vertical plate 2 , and the other end of the second hydraulic cylinder 41 is fixedly connected to the vertical plate 34 .

[0028] The slide column 42 is used for sliding connection with the vertical plate 34, providing a sliding track for adjusting the distance between the two polishing mechanisms. The second hydraulic cylinder 41 controls the movement of the two polishing mechanisms by its own extension and contraction, so that wood boards of different widths can be polished.

[0035] Working principle:

[0036] The extension and retraction of the first hydraulic cylinder 37 is used to control the lifting and lowering of one section of the sanding plate 32. The other end of the sanding plate 32 is kept in rotation connection with the frame 31, so as to achieve the purpose of adjusting the angle of the sanding plate 32, so that the polishing roller 36 can sand and polish the inclined surfaces of different angles. At the same time, the spacing between the two polishing mechanisms can be controlled by adjusting the second hydraulic cylinder 41, so that the sanding and polishing of plates of different widths can be completed.

[0037] The third hydraulic cylinder 51 is used to control the spacing of the L-shaped limit plate 52, so that the L-shaped limit plate 52 can limit the wooden boards of different widths in the middle to prevent the horizontal component force generated when polishing the inclined surface from pushing the board. The front plate 61 is used to install the fourth hydraulic cylinder 62, and the fourth hydraulic cylinder 62 pushes the board into the polishing mechanism.
