Embodiment 1

[0032] Embodiment 1, the present invention is a microbial gene quantitative sampling device for biological control, which is characterized in that it includes a bottom plate 1, and the bottom plate 1 can be placed on the ground or on a test bench, which is the basis of the present invention, and the subsequent structure provides The base is fixed, the base plate 1 is rotatably connected with a large gear 2, and the upper end of the large gear 2 is coaxially rotatably connected with a pinion 3. The specific rotational connection method can be fixed at the axis of the large gear 2 Connect the rotating shaft and set the pinion 3 on it, that is, the rotation of the large gear 2 cannot drive the rotation of the small gear 3. In order to ensure the achievement of its effect, it can be placed on the rotating shaft connected by the rotation of the large gear 2 and the small gear 3 Bearings are provided. The large gear 2 and the pinion 3 are essentially a disk with teeth evenly fixed on...

Embodiment 2

[0038] Embodiment 2. On the basis of Embodiment 1, the quantitative automatic straw includes a straw holder 10 fixedly connected to the upper end of the lifting screw 5. The straw holder 10 is used to provide a fixed foundation for the subsequent structure. The straw holder 10 and the fixing method of the lifting screw 5 can also be detachably connected through the keyway, which is convenient for the replacement of parts. The straw holder 10 is fixedly connected with a hollow straw barrel 11, and the straw barrel 11 is a common straw. There is a hole at the lower end, which is convenient for absorbing the sample liquid. The upper end of the suction tube 11 is connected with a transfer air chamber 12, and one side of the transfer air chamber 12 is connected with an air channel 13, and the left and right slides in the air channel 13 are connected with The piston 14 is sealed and fitted to the inner wall of the air passage 13, that is, when the lower end of the straw barrel 11 is ...

Embodiment 3

[0039] Embodiment 3, on the basis of Embodiment 2, an air hole 18 is provided at the upper end of the transfer air chamber 12, and a sealing plug 19 is slid up and down on the air hole 18, and the sealing plug 19 is connected by a spring and the The transit air chamber 12 is connected, refer to Figure 10 , the sealing plug 19 and the air hole 18 can be hermetically bonded. When the present invention is in normal use, the sealing plug 19 is pressed tightly on the air hole 18 by a spring to ensure the airtightness of the transfer air chamber 12. When the tester needs to lift the sealing plug 19, he can lift it by pulling the fixedly connected handle on the sealing plug 19. One end of the threaded sleeve 15 is fixedly connected with a push plate 20, and the tester can manually adjust by pushing the push plate 20. The position of the piston 14, one end of the air passage 13 communicates with the transfer air chamber 12, the other end of the air passage 13 is fixedly connected wit...

Abstract

The invention relates to a quantitative microbial gene sampling device for biological control. The problems that the conventional sampling device is low in accuracy, the whole liquid taking process needs to be manually operated, the accuracy is difficult to control and automation cannot be realized so as to cause low efficiency can be effectively solved. According to the solved technical scheme, the quantitative microbial gene sampling device comprises a bottom plate, wherein a gearwheel is rotationally connected onto the bottom plate; the upper end face of the gearwheel is coaxially rotationally connected with a pinion; the pinion is coaxially fixedly connected with a threaded sleeve; a lifting screw is in screw-thread fit with the interior of the threaded sleeve; the upper end of the lifting screw is fixedly connected with a quantitative automatic pipette; the upper end face of the gearwheel is fixedly connected with a chute; and the lower end of the quantitative automatic pipette isfixedly connected with a slide key arranged in the chute. The quantitative microbial gene sampling device disclosed by the invention is simple in structure and high in practicality, and the labor force and time for accurate quantitative sampling can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of microbial gene sampling, in particular to a microbial gene quantitative sampling device for biological control. Background technique [0002] Biological control is a method of using one organism to deal with another organism, which can be roughly divided into three categories: controlling pests with insects, controlling pests with birds and controlling pests with bacteria. It is a method of reducing the population density of harmful organisms such as weeds and pests. It takes advantage of the interrelationships between biological species to suppress another or another type of organisms with one or one type of organisms. Its biggest advantage is that it does not pollute the environment, which is incomparable to non-biological pest control methods such as pesticides. [0003] Among them, the use of bacteria to control pests is also called microbial pest control, which mainly uses the pathogenic microorgan...
