Detailed Description

As shown in fig. 1-3, the present invention provides a flat roof ceiling sander, which comprises a body 3, a grinding disc 32 and a dust suction device, wherein the grinding disc 32 is mounted on a rotating shaft 30 of the body 3, the dust suction device comprises a collecting mechanism mounted on the body 3 and a dust storage mechanism carried on the back of a worker; the collecting mechanism comprises a dust collecting cavity 2 and an elastic extension tube 1, the dust collecting cavity 2 is fixedly arranged at the head of the machine body 3, the elastic extension tube 1 is fixedly arranged at an opening above the dust collecting cavity 2, a rotating shaft 30 of the machine body 3 upwards penetrates through the dust collecting cavity 2 and extends into the elastic extension tube 1, and a grinding disc 32 arranged in the elastic extension tube 1 is arranged at the head of the rotating shaft 30. An exhaust port arranged at the bottom of the dust collection cavity 2 is communicated with a dust collection port of a dust collector 6 of the dust storage mechanism through a flexible connecting pipe 4. The dust collector 6 is provided with a belt 61 worn on the body of a worker, so that the dust collector is convenient for the worker to carry.

When the dust collector is used, a worker holds the handle 31 on the machine body 3 and exerts pressure upwards to press and contract the elastic extension tube 1, the grinding disc 32 is abutted to the ceiling of the flat slab to carry out grinding operation, meanwhile, the dust collector 6 sucks out dust falling into the dust collection cavity 2 through the flexible connecting tube 4 for centralized treatment, and a negative pressure dust collection area is formed between the dust collection cavity 2 and the elastic extension tube 1, so that the dust generated by grinding can be effectively prevented from splashing outwards, and the construction environment is prevented from being polluted.

The inner wall of the dust collection cavity 2 horizontally protrudes inwards to form an annular boss 22, and the filter plate 5 is horizontally and detachably arranged on the boss 22. The side wall of the dust collection chamber 2 is provided with a sealing door 21, and the filter plate 5 arranged in the dust collection chamber 2 can be replaced and cleared by opening the sealing door 21. The filter plate 5 is designed into an annular structure; the annular filter plate 5 is formed by splicing two semicircular rings or a plurality of fan rings, and each splicing block of the filter plate 5 is detachably and fixedly connected. The rotary shaft 30 is disposed vertically upward through a through hole 50 in the center of the filter plate 5. The filter plate 5 can filter the waste material of polishing, avoids causing the inside jam of storing up dirt mechanism.

In this embodiment, the annular filter plate 5 is composed of two semicircular rings, and the joint between the two semicircular rings is detachably and fixedly connected through a snap structure (not shown in the figure). When the waste material of polishing blocks up the through-hole on the filter plate 5, the filter plate 5 of compriseing two semicircle rings can greatly make things convenient for the dismantlement installation of filter plate 5.
