Abstract
The utility model discloses a bacterial liquid inoculating needle, which belongs to an inoculating tool; aims at providing a cordyceps militaris liquid strain inoculating needle which has simple structure, convenient operation and even inoculation and can realize inoculation without uncovering a film. The needle comprises a hollow needle rod fixedly connected with a needle seat and a needle point fixed at the front end of the hollow needle rod; the needle point (4) is a solid cone structure with a sharp front end, four through grooves (3) which are uniformly distributed according to a spiral line are arranged on the surface of the needle bar (2) at positions close to the needle point (4), and each through groove (3) is communicated with the inner cavity of the needle bar (2). The utility model has simple operation, high inoculation efficiency, even fungus liquid spraying and difficult formation of blockage, and is a tool suitable for not only cordyceps militaris strain inoculation, but also liquid fungus inoculation of cordyceps cicadae, winter mushrooms, hericium erinaceus, oyster mushrooms, flammulina velutipes, edible fungi, tremella, ganoderma lucidum and the like.
Description
Technical Field
The utility model relates to a bacterial liquid inoculation tool, in particular to a liquid bacterial inoculation needle.
Background
Inoculation is a very important link in the cultivation process of cordyceps militaris. The common practice is to uncover the plastic film covered on the cultivation box, uniformly spray the liquid strain on the surface of the culture medium in the cultivation box by using a spraying device, and then seal the cultivation box by using the plastic film after the inoculation is completed. The operation method is troublesome and low in efficiency, and is easy to pollute the culture medium and has high requirements on the technical proficiency and the professional level of personnel.
In order to overcome the defects, the utility model patent with the publication number of CN209201710U discloses a liquid strain inoculation device with a plurality of inoculation needles, wherein a plurality of inoculation needles with two injection holes are arranged on the side surface of a needle rod, and each inoculation needle is driven to rotate by a motor fixed on the shell through a transmission belt, so that high-efficiency and uniform spraying inoculation is realized. The inoculation device can realize inoculation of Cordyceps militaris liquid strains without uncovering a film, so that the pollution of a culture medium is avoided to the greatest extent, and the inoculation efficiency is improved; but due to the following drawbacks:
1) Because the spraying holes at two sides of the inoculating needle have the defect of small spraying coverage, the inoculating needle is required to be driven to rotate by a belt transmission device, so that the structure is complex and the cost is high;
2) The spray hole is easy to be blocked and the dredging is more troublesome.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the cordyceps militaris liquid strain inoculation needle which has the advantages of simple structure, convenient operation and uniform inoculation and can realize inoculation without uncovering a film.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the needle comprises a hollow needle rod fixedly connected with a needle seat and a needle point fixed at the front end of the hollow needle rod; the needle point is a solid cone structure with a sharp front end, four through grooves which are uniformly distributed according to a spiral line are arranged on the surface of the needle bar and are close to the needle point, and each through groove is communicated with the inner cavity of the needle bar.
The needle seat is a pipe joint with a plurality of conical ring grooves distributed on the surface.
Compared with the prior art, the utility model has the following advantages due to the adoption of the technical scheme:
1) The inoculation can be realized without uncovering the film, so that the risk of pollution to the culture medium can be effectively reduced, the operation is simple, and the inoculation efficiency is high;
2) Because the needle bar is provided with four through grooves distributed according to a spiral line, even covering and spraying of bacterial liquid can be realized without rotating the needle bar;
3) The through grooves uniformly distributed according to the spiral line are adopted to replace the injection holes positioned on the two sides of the needle bar, so that the blockage is not easy to form, and the blockage dredging is more convenient even if the blockage is generated.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure: needle seat 1, needle bar 2, through groove 3, needle tip 4.
Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
As shown in fig. 1: the hollow needle rod 2 is fixedly butted and communicated with the needle seat 1, the other end of the needle rod 2 is fixedly connected with a sharp solid cone body, and the solid cone body forms a needle point 4. Four through grooves 3 which are uniformly distributed according to a spiral line are arranged on the surface of the needle bar 2 and are close to the needle tip 4, and each through groove 3 is communicated with the inner cavity of the needle bar 2.
In order to facilitate the stable connection with the hose (not shown in the figure), the needle holder 1 adopts a pipe joint with a plurality of conical ring grooves (not shown in the figure) distributed on the surface.
In use, the needle holder 1 is connected to a spraying device (e.g. a syringe) via a hose. The plastic film covered on the cultivation box is pierced by the needle point 1, the needle bar 2 is vertically inserted into the cultivation box, the liquid strain is quantitatively sprayed to the culture medium by the spraying device, and then the needle bar 2 is pulled out.
Claims (2)
1. A Cordyceps militaris liquid strain inoculating needle comprises a hollow needle rod fixedly connected with a needle seat, and a needle point fixed at the front end of the hollow needle rod; the method is characterized in that: the needle point (4) is a solid cone structure with a sharp front end, four through grooves (3) which are uniformly distributed according to a spiral line are arranged on the surface of the needle bar (2) at positions close to the needle point (4), and each through groove (3) is communicated with the inner cavity of the needle bar (2).
2. The cordyceps militaris liquid spawn inoculation needle according to claim 1, wherein: the needle seat (1) is a pipe joint with a plurality of conical ring grooves distributed on the surface.
