Microbiological detection sampling device and operation method

Abstract

The invention relates to a microbiological detection sampling device and an operation method. The microbiological detection sampling device comprises a machine base, a half gear, a moving frame, a lead screw, a nut seat, a rack frame and a sampling gear, wherein a rear plate is arranged on the right side of the machine base; a motor seat is arranged on the right side of the bottom of the rear plate; a central hole is formed in the middle of the rear plate; a rear plate sliding groove is formed in the end surface of the left side of the rear plate; a sampling area is arranged at the bottom of the machine base; two side plates which are symmetrically arranged are arranged on the front side and the rear side of the machine base; a rack sliding groove is formed in the upper portion of each side plate; two side plate sliding grooves which are symmetrically arranged are formed in the side surfaces of the two side plates; a left rack is arranged on the right side of the rear side plate; a right rack is arranged on the right side of the front side plate; the left rack and the right rack are arranged on the inner sides of the side plates; a half gear shaft is arranged in the middle of the half gear; an elliptical hole is formed in the middle of the moving frame; an upper rack is arranged on the upper portion of the elliptical hole; a lower rack is arranged on the lower portion of the elliptical hole; a connecting plate is arranged on the front side of the moving frame; a lead screw hole is formed in the middle of the connecting plate; and the two sides of the moving frame are connected with the two sides of the rear plate sliding groove in a sliding manner.

Description

technical field [0001] The invention relates to the field of microorganism detection and sampling, in particular to a microorganism detection and sampling device and an operation method. Background technique [0002] During the microbial sampling process, it is necessary to wipe the area within 50cm² with a cotton swab. During the wiping process, the cotton swab must be rotated continuously, and no omissions can be made to ensure the integrity of the sampling. There are problems of incomplete wiping and inaccurate sampling during manual sampling. A need exists for means to solve the above problems. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a microbial detection and sampling device and an operation method that does not leave any dead space, standardizes sampling, and automatically samples. [0004] The purpose of the present invention is to realize through the following technical solutions...
