Specifically, long section of thick bamboo 32 is ceramic composite pipe, roller 2 runs through protection machanism 3 and is connected with outside motor, and this ceramic composite pipe wearing and tearing when reducing the rotation of roller 2 in long section of thick bamboo 32 are high.

Specifically, two semicircle baffle 71 laminates mutually and is the cylinder, and the columniform internal diameter is greater than the diameter of roll body 1, and two semicircle baffles 71 are corresponding, constitute a cylinder, and the parcel is in the outside of roll body 1, strengthens the protection to roll body 1.

The working principle is as follows: firstly, a protection mechanism 3 penetrates through the roll shafts 2 on two sides of the roll body 1, the protection mechanism 3 is sleeved on two sides of the roll body 1, an inverted L-shaped limiting rod 4 at the upper end of the protection mechanism 3 is positioned at the upper end of the roll body 1, a left inverted L-shaped limiting rod 4 and a right inverted L-shaped limiting rod 4 correspond to each other, an H-shaped rotating block 41 is limited between the two inverted L-shaped limiting rods 4, a rod body of each inverted L-shaped limiting rod 4 penetrates through two circular grooves 42 of the H-shaped rotating block 41 close to the lower end of the H-shaped rotating block and is screwed down, the protection mechanism 3 is limited, one side of a limiting ring 31 on the protection mechanism 3 is clung to the outer surface of one side of the roll body 1, the roll shaft 2 penetrates through the inside of a long barrel 32 and is connected with a rotating shaft of an external motor, the other limiting ring 31 is clung to the position of the connecting part of the roll shaft 2 and the motor, the water splash can splash to the connection part of the roller shaft 2 and the roller body 1 and the connection part of the roller shaft 2 and the motor, the water splash is easy to rust, the rotation is influenced, the roller shaft 2 is electrified and is easy to be polluted by water, the structure not only can prevent the roller shaft 2 from rusting when meeting water and can reduce the risk of electric leakage, then, two fixed blocks 52 at the lower end of the arc-shaped panel 51 are clamped at the position close to the upper end in the H-shaped rotating block 41, the two-way bolt penetrates through the circular groove 42 and is screwed tightly, the H-shaped rotating block 41 is rotated, the cleaning mechanism 5 at the upper end of the H-shaped rotating block can be rotated to the lower end, the arc-shaped panel 51 is tightly attached to the outer surface at the upper end of the roller body 1, the roller shaft 2 is started, the roller body 1 rotates, the outer surface of the roller body 1 rubs with the brush of the arc-shaped panel 51 in the, the shielding mechanism 7 is arranged at the front end and the rear end of the arc panel 51, the arc strips 72 on the semicircular baffles 71 are clamped into the flat concave blocks 53, the semicircular baffles 71 are limited, the semicircular baffles 71 at the front end and the rear end of the arc panel 51 are put down, the two semicircular baffles 71 correspond to each other to form a cylinder which is wrapped outside the roller body 1, the leak holes 74 at the bottom of the semicircular baffles 71 can keep ventilation inside, meanwhile, the mechanism not only can properly block dust on the outer surface of the roller body 1 and can also avoid the outer surface from being worn, before the roller body 1 is used, the roller body 1 structure is required to be overhauled, the inverted L-shaped limiting rod 4 is rotated to turn over by one hundred eighty degrees, the inverted L-shaped limiting rod 4 is rotated to the lower end of the roller body 1, the snap ring 61 on the supporting mechanism 6 is rotated by one hundred eighty degrees, the supporting mechanism 6 is limited at the lower end of the inverted L-shaped limiting rod 4, and both are crisscross to be placed, stand whole roll body 1 structure, and this mechanism is laid conveniently, and the convenience is comparatively convenient to the maintenance detection of roll body 1.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
