Abstract
The utility model discloses an AM fungal spore extractor, which comprises an elastic air bag, a knob type flow regulating valve and a suction pipe, wherein the suction pipe is connected with the elastic air bag in a sealing way, and the knob type flow regulating valve is arranged on the suction pipe and is connected with the elastic air bag; the picker can transfer small granular AM fungi to a laboratory bench from an AM fungi containing vessel.
Description
Technical Field
The utility model relates to a flue-cured tobacco field of planting, in particular to AM fungal spore extractor.
Background
The AM fungi are beneficial microorganisms, can form a symbiotic system with the root systems of most higher plants, can improve the quality of tobacco seedlings after being used together with the tobacco seedlings, improve the nutritional status and the physical and chemical properties of soil of the plants, promote the growth of the plants, improve the stress resistance and the disease resistance of the plants and the like, can promote the opening of upper leaves and improve the yield and the quality of tobacco leaves on the premise of using less fertilizers and pesticides, but the AM fungi in the soil are insufficient and need to be cultured, and the cultured AM fungi need to be tested to verify whether the cultured AM fungi meet the requirements or not; since granular AM fungi are very small and it is very troublesome to sample from a container onto a test bed, it is desirable to design an AM fungal spore extractor that can easily sample and transfer to a test bed.
Disclosure of Invention
In view of this, the utility model aims at providing an AM fungal spore extractor, can easily take a sample from the splendid attire ware and transfer to the test bench, it is very convenient to use.
The utility model aims at realizing through the following technical scheme:
the AM fungal spore extractor comprises an elastic air bag, a knob type flow regulating valve and a straw, wherein the straw is connected with the elastic air bag in a sealing manner, and the knob type flow regulating valve is arranged on the straw and connected with the elastic air bag.
Furthermore, an air tap is arranged on the side, deviating from the knob type flow regulating valve, of the elastic air bag, and the air tap is smaller than half of the pipe diameter of the knob type flow regulating valve.
Furthermore, an interception net (5) is arranged at the end, close to the elastic air bag (1), in the straw, and the mesh size of the interception net (5) is 400 meshes.
Furthermore, the caliber of a suction port of the suction pipe is less than 0.5 mm.
Further, the straw is a glass straw.
Furthermore, a cylinder which is crossed and vertical to the suction pipe is arranged on the suction pipe, an inner hole of the cylinder is a threaded hole, a screw is screwed in the threaded hole, a overflowing hole which is communicated with the inner hole of the suction pipe is radially arranged on the cylinder, and the diameter of the overflowing hole is consistent with that of the inner hole of the suction pipe.
Still further, the gasbag is equipped with the gas pocket, be equipped with the check valve in the gas pocket.
The utility model has the advantages that:
the utility model discloses a AM fungal spore extractor, when the elasticity gasbag was extruded, form the negative pressure state in the straw, let go up the elasticity gasbag, the straw can follow the splendid attire household utensils and absorb the AM fungus, later extrude the elasticity gasbag again and put the AM fungus on the test bench, the setting up of knob formula flow control valve can guarantee that the picker only absorbs the AM fungus on splendid attire household utensils surface at the in-process that inhales the AM fungus, can avoid inhaling in the straw with a large amount of other liquid, it is very convenient to use.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
Drawings
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, in which:
fig. 1 is a front sectional view of the present invention.
Fig. 2 is a top cross-sectional view of the present invention.
Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.
As shown in figure 1-2, the AM fungal spore extractor comprises an elastic air bag 1, a knob type flow regulating valve 2 and a suction pipe 3, wherein the suction pipe 3 is connected with the elastic air bag 1 in a sealing way, the knob type flow regulating valve 2 is arranged at the connecting end of the suction pipe 3 and the elastic air bag 1, the flow regulating valve 2 is completely opened by a knob before the elastic air bag 1 is extruded, when the suction pipe 3 absorbs AM fungi, air passing through the flow regulating valve is reduced by the knob, the picking device can only absorb AM fungi on the surface of a container in the process of absorbing AM fungi, a large amount of other liquid can be prevented from being absorbed into the suction pipe, the knob type flow regulating valve is the prior art, a cylinder which is intersected and vertical with the suction pipe is preferably arranged on the suction pipe, the inner hole of the cylinder is a threaded hole, a screw is screwed in the threaded hole, a flow hole communicated with the inner hole of the suction pipe is radially arranged on the, such flow control valve can realize slowly breathing in, and the size of breathing in is adjusted through the screw, be equipped with gas pocket 4 on the gasbag, be equipped with the check valve in the gas pocket, the check valve can exhaust when pressing the gasbag, can not follow the afterbody and admit air after the hand is loosened.
When using this picker, when elasticity gasbag 1 is extruded, form negative pressure state in the straw 3, let go up elasticity gasbag 1, straw 2 can absorb the AM fungus from the splendid attire household utensils, later extrude elasticity gasbag 1 again and put the AM fungus on the test bench, the setting of knob formula flow control valve 2 can guarantee that the picker only absorbs the AM fungus on splendid attire household utensils surface at the in-process of inhaling the AM fungus, can avoid inhaling in the straw with a large amount of other liquid, and it is very convenient to use, and this picker still can one-hand operation.
An interception net 5 is arranged in the knob type flow regulating valve 2 close to the end of the elastic air bag 1, the mesh size of the interception net 5 is 400 meshes, and the arrangement of the interception net 5 can avoid the difficulty that AM fungi are discharged from the elastic air bag 1.
