When the vertical adjustment and the horizontal rotation of the cleaning shell 20 are mixed, dead spots can be more effectively avoided.
When the crankshaft 12 rotates, the linkage rod 13 structure connected with the crankshaft can drive the cleaning shaft 16 to reciprocate, so that the inner surface and the outer surface of the branch pipe with the test tube are cleaned. Meanwhile, the main body with the branch test tubes and the branch tubes are cleaned, so that the cleaning effect is better, and the pollution to other cleaned parts caused by respectively cleaning in sequence is avoided.
The bristles 30 are in contact with the surface of the test tube for cleaning, and have certain deformation characteristics, meanwhile, in the invention, the bristles 30 need to have certain supporting elastic capacity, and can form supporting force after extrusion deformation so as to effectively clamp and position the test tube (the common bristles 30 can also have supporting capacity after extrusion and accumulation). The specific structure of the bristles 30 at different positions is not emphasized in the description, and the bristles 30 with different materials, lengths, hardness, density and directions can be adopted according to different positions, so that the judgment can be made according to actual conditions and common knowledge. It should be emphasized that, in some joints, the brush bristles 30 may be extended obliquely outward to ensure coverage, and simultaneously avoid collision between devices during relative movement, for example, at the positions of the branch pipes, the positions between the side barrel 28 and the brush plate 27 and the top barrel 29, for example, at the peripheral position corresponding to the rotational connection of the cleaning shell 20, the coverage of the brush bristles 30 needs to be ensured during the vertical adjustment rotation of the cleaning shell 20, and effective coverage can be ensured by outward inclination, density improvement and other forms to avoid leakage. The bristles 30 are shown in a simplified manner in the drawings.
The bristles 30 uniformly distributed on the surface of the cleaning shaft 16 also limit the cleaning shaft 16 to avoid collision. In order to improve the limitation of the motion track of the cleaning shaft 16, a limit bracket made of rubber material can be additionally sleeved and added, so that the cleaning shaft 16 is driven by the crankshaft 12 to reciprocate in the direction coaxial with the branch pipe, and a small allowable variable of up-and-down displacement can exist, so that the whole body can generate up-and-down displacement, the contact form of the brush bristles 30 is changed, and the cleaning effect is improved.
