Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent production, in particular to a sampling and detection device for agricultural microbial agent production. Background Art

[0002] A sampling and testing device is usually a device specially designed for collecting samples and detecting microorganisms. When testing the production of agricultural microbial agents, a sampling device is usually used to sample the microbial agents, and then the samples are tested through a testing device to detect whether the microbial agents are qualified, thereby achieving high-quality production of microbial agents and ensuring the effectiveness of the use of microbial agents.

[0003] A Chinese patent application numbered CN202321061750.0 discloses a microbial agent detection sampling device. Through the filter screen, the liquid to be sampled can be further filtered to prevent the precipitated liquid from being muddied when the sampling tube is sampling, causing impurities to be taken up with the liquid and affecting the detection results. Through the limit ring, the rotating shaft can be rotated down the conical tube, and the rotating shaft will not shake when it loses its fixation, resulting in the failure to align the sampling tube in the later stage. Through the fixing rod, the rotating shaft can be connected to the conical tube, so that the rotating shaft drives the conical tube downward for sampling. Sample; however, when the above-mentioned microbial inoculant detection sampling device is in use, the rotating shaft is driven to rotate by the knob, so that the fixed rod drives the conical tube to rotate downward, and then the rotating shaft is limited by the limiting ring to prevent the conical tube from rotating downward, and then the bacterial agent to be detected is filtered and collected through the filter screen to complete the detection. However, when the limiting ring limits the rotating shaft, the rotating shaft is prone to rotate, and it is inconvenient to fix it, resulting in the conical tube being unstable, affecting the accuracy and precision of sampling and detection, so that the test result may deviate from the actual situation, thereby reducing the reliability and accuracy of the device.

[0027] The utility model provides Figure 1 and Figure 2 The sampling and detection device for the production of agricultural microbial inoculants shown in the figure comprises: a sampling barrel 1, a rotating shaft 3 is inserted into the interior of the sampling barrel 1, and a conical barrel 2 is screwed to the bottom of the sampling barrel 1, a filter plate 6 is installed on the top of the conical barrel 2, the rotating shaft 3 is connected to the filter plate 6, and a rotating disk 7 is installed on the top of the rotating shaft 3, and an anti-slip sleeve is fixed to the outer wall of the sampling barrel 1, and a plurality of evenly distributed grooves are provided on the outer wall of the anti-slip sleeve.

[0028] As can be seen from the above, when in use, the sampling tube 1 is placed in the microbial agent to be tested, and the rotating disk 7 is rotated to drive the rotating shaft 3 to rotate inside the sampling tube 1. The rotation of the rotating shaft 3 drives the filter plate 6 to start rotating, and the rotation of the filter plate 6 drives the conical tube 2 to rotate, so that the conical tube 2 is separated from the sampling tube 1, and then the microbial agent is filtered and sampled through the filter plate 6, and the sampled microbial agent is transferred to the testing location, thereby completing the sampling and testing operation of the agricultural microbial agent.

[0029] refer to Figure 2-Figure 4As shown, the fixing mechanism 4 is located between the rotating disk 7 and the sampling tube 1, and the fixing mechanism 4 is used to fix the rotating shaft 3.
