Embodiment 1

[0018] Embodiment one: if figure 1 with Figure 5 As shown, the granary sampling analysis of the present invention uses a periodic gating device for pumping insects and pumping gas, including a fixed plate 2 with a groove 1 on the surface, a moving plate 3 arranged in the groove 1, and a conduit 4 perpendicular to the moving plate 3 The center of the moving disk 3 is connected with a moving disk motor 5 for driving the moving disk 3 to rotate in the groove 1. The fixed disk 2 is provided with a circle of air guide holes 6 that are evenly arranged around the center of the moving disk 3. The moving disk 3 is provided with There is a through hole 7. When the moving disc rotates, the through hole 7 can communicate with each air guide hole 6 one by one. When designing, the horizontal distance from the center of the through hole 7 to the center of the moving disc 3 is the same as that between the center of each air guide hole 6 and the moving disc. The horizontal distances between ...

Embodiment 2

[0021] Embodiment two: if figure 2 with Figure 5 As shown, the difference with Embodiment 1 is that the power drive mechanism includes a bracket 9 arranged on the moving disk 3 and an electromagnet 14 arranged on the bracket 9, the conduit 4 is passed through the electromagnet 14, and the upper part of the conduit 4 is made of iron. Made of magnetic material, the upper end of the conduit 4 is provided with a limit block 15, the limit block 15 and the conduit 4 are integrally formed, the air extraction hole 26 is set at the center of the top of the limit block 15, and the conduit 4 is provided with an electromagnet 14 and a limit block Return spring 16 between 15.

[0022] When in use, the movable disk motor 5 drives the movable disk 3 to rotate at a certain angle, an air guide hole 6 just corresponds to the through hole 7 up and down, the electromagnet 14 is energized, and the magnetic attraction force of the electromagnet 14 to the upper limit block 15 of the conduit 4 is ...

Embodiment 3

[0023] Embodiment three: as image 3 with Figure 5 As shown, the difference from Embodiment 1 is that the power drive mechanism includes a bracket 9 arranged on the moving disk 3, a stepping motor or a servo motor 10 arranged on the bracket 9, and two vertically arranged on the moving disk 3. A guide post 17 and a pressure plate 18 that is sheathed on the two guide posts 17, each guide post 17 is provided with a reset spring 16 between the press plate 18 and the moving disk 3, and the stepper motor or servo motor 10 Cam 19 is provided on the output shaft, and cam 19 can adopt such as image 3 In the shown eccentric wheel structure, the circumferential surface of the cam 19 is pressed against the upper surface of the pressure plate 18 . Cam 19 also can adopt the cam that has other curved surface profile that composite drive requires. The conduit 4 is vertically threaded on the pressure plate 18 and detachably connected to the pressure plate 18 by a fastening nut 20 , and th...

Abstract

The invention discloses a periodic gating unit for suction of worms and air and for granary sampling analysis. The periodic gating unit comprises a fixed disc provided with a groove, a moving disc arranged in the groove, a guide pipe perpendicular to the moving disc, and a moving disc motor which is connected with the moving disc and used for driving the moving disc to rotate in the groove. The fixed disc is provided with a circle of air guiding holes around the center of the moving disc, and the air guiding holes are evenly distributed. The moving disc is provided with a through hole, and when the moving disc rotates, the through hole can be communicated with the air guiding holes one by one. An elastic pipe head is arranged at the lower end of the guide pipe. The moving disc is provided with a power driving mechanism, wherein a power output end of the power driving mechanism is connected with the guide pipe, and the power driving mechanism is used for controlling the guide pipe to move along the through hole in the axial direction so that sealing between the elastic pipe head and edges of the air guiding holes is realized. The periodic gating unit for suction of the worms and the air and for the granary sampling analysis is reasonable in design and simple in structure, enhances the air tightness of an air suction pipeline, eliminates the air leakage situation and improves work efficiency and accuracy of gas detection results.

Description

technical field [0001] The invention relates to a granary sampling and analyzing insect pumping periodic gating device for sampling pests or gas extraction and testing in a granary. Background technique [0002] During the storage of grain in the granary, the pests in the granary are very harmful to the grain, and the air quality in the granary also has a great impact on the storage of the grain. The deterioration of the pest and air quality will bring great economic losses to the stored grain. . For this reason, it is very necessary to be able to forecast early and detect the concentration of stored grain pests, oxygen, carbon dioxide, hydrogen sulfide and other gases in the granary at any time, so as to take timely countermeasures. Chinese utility model patent ZL02269339.4 discloses a granary pest sampler. The periodic gating device in this pest sampler is not air-tight and often leaks air, which makes the efficiency of insect extraction and air extraction low. , especia...
