Problems solved by technology

Due to the characteristics of large sample size, many types of samples and fast circulation speed in food safety rapid inspection, the detection process has very high requirements on efficiency, but the pretreatment of samples often takes up most of the time in the detection process, so it will Seriously affect the detection efficiency
At present, the laboratory and on-site quick inspection mostly use the traditional knife cutting or shearing, and then crush it with a cooking machine, and finally use a spoon to weigh and quantify it with a balance. The process is relatively cumbersome and labor-intensive.
[0003] Now although a fast smashing sampling gun is designed to try to solve the problem of low efficiency of quick inspection
However, because it uses stud grinding and crushing, this crushing method not only needs to design a high-strength side wall and the grinding stud to form a grinding space, but also has low crushing efficiency.
In addition, the structure used to collect and store crushed samples is a test tube, and a diversion groove needs to be designed so that the sample at the front end of the sampling gun flows into the test tube through the diversion groove. The overall structure of sampling is complex and high, and once the diversion groove is blocked difficult to sample
It can be seen that the improved sampling gun still has many disadvantages and cannot achieve the expected purpose

Embodiment Construction

[0028] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0029] Such as Figure 1-6 As shown, a special sample pulverization quantitative sampler for food safety quick inspection, including the main body of the sampler, a pistol-shaped protective shell 2 covering the outside of the sampler, a blade 9 for crushing samples of the sampler, a central axis drill bit 8, a semi-quantitative A sample cup 11, a cutter head sheath 7, a reversible motor 4 and a mobile power source 1 composed of a lithium battery pack.

[0030] In order to make the rotational speed provided by the motor 4 both automatic and manual, the central shaft between the semi-quantitative sample cup 11 and the motor 4 is fitted with a frequency converter 6 and a frequency converter for automatically regulating the rotational speed of the motor. Gearbox 5 for manual control of motor speed. ...

Abstract

The invention provides a food safety fast inspection special sample crushing quantitative sampler including a sampler main body and a protective outer shell; the sampler main body comprises a motor, a mobile power supply and an on-off key; the front end of the motor is movably connected with a middle shaft; the front end of the middle shaft is provided with a cusp-shaped middle shaft drill, the front end of the middle shaft is sleeved with a blade in a connection manner, the blade is fixedly connected with the middle shaft, and the blade is externally sleeved with a semi-quantitative sample holding cup; a cup mouth of the semi-quantitative sample holding cup is downwards, and the edge of the cup mouth is ground with a knife edge; the center of the cup bottom of the semi-quantitative sample holding cup is provided with a mounting hole; the middle shaft passes through the mounting hole and is in detachable connection with the cup bottom; a part, between the semi-quantitative sample holding cup and the motor, of the middle shaft is provided with a frequency converter and a gearbox in a sleeved connection manner, the frequency converter is electrically connected with the motor, and the gearbox is in gear connection with the motor; the outer side of the semi-quantitative sample holding cup is fixedly connected with a positioning ring. The food safety fast inspection special sample crushing quantitative sampler has the beneficial effects that the design can synchronously and rapidly realize sampling, sample breaking and semi quantification; and the sampling process is simplified, the sampling time and labor are saved, and the pretreatment efficiency of fast inspection samples is greatly improved.

Description

technical field [0001] The invention relates to the technical field of testing and sampling, in particular to a special sample crushing and quantitative sampler for quick food safety inspection. Background technique [0002] The pretreatment of food testing samples usually includes steps such as sampling, crushing, weighing, extraction and separation. Due to the characteristics of large sample size, many types of samples and fast circulation speed in food safety rapid inspection, the detection process has very high requirements on efficiency, but the pretreatment of samples often takes up most of the time in the detection process, so it will Seriously affect the detection efficiency. At present, laboratory and on-site quick inspections mostly use traditional knife cutting or scissors, then crush them with a cooking machine, and finally use a spoon to weigh and quantify them with a balance. The process is relatively cumbersome and labor-intensive. [0003] Although a fast s...
