obvious and easier to understand, the present invention will be further explained in detail

with reference to the drawings and specific embodiments.

Referring to fig. 1-2, the invention provides a double-layer insect net for collecting jujube

thrips, comprising a rod (1) with tubular structure, wherein, there is a reciprocating

telescopic mechanism (5) arranged at the top of rod (1) and the top of the reciprocating

telescopic mechanism (5) is fixedly connected with a metal net ring (2) which is sheathed

and fixedly connected with an outer net (4). An inner net (3) is sheathed in the outer net

(4) and in removable connection with the outer net (5). Besides, the inner net (3) has a

bigger aperture than outer (4) net.

The reciprocating telescopic mechanism (5) specifically comprises a micro-motor (6),

which is fixed in the lumen of rod (1). The output end of micro-motor (6) is fixedly

connected with a helical gear (7), which is in mesh connection with a body of helical gear

(8), and the body of helical gear (8) is connected in the lumen of rod (1) by a shaft. The

side of the body of helical gear (8) away from helical gear (7) is fixed connected with

eccentric columns (9), which is axially connected with a link rod (10). The link rod is

axially connected with a fixed rod (11). A sleeve rod (12) fixed connected on the top of

the fixed rod (11). At the sleeve rod (12) bottom, there is a slot (17) with the fixed rod

(11) passing through, and the slot (17) is sheathed on the outer side of the rod (1). The

sleeve rod (12) is fixed connected with the metal net ring (2).

Considering that jujube thrips body is about 1.2 mm long and 0.25 mm wide, use16 mesh

gauze as inner net (3) to make collected thrips enter outer net (4) through mesh holes of

inner net (3), and keep impurities such as jujube flowers larger than mesh holes left in

inner net (3). Use 80 mesh gauze as outer net (4) to collect jujube thrips samples. The

tops of inner and outer nets are connected by a zipper and supported by a 0.5mm wire loop, whose mouth end is linked with the iron rod (1) with diameter of 1.8 cm and length of 50 cm through a screw.

To make it easier to hold the net and prevent slipping hands, the further optimization

scheme is to set a handle (13) with skid-proof grains at the bottom of rod (1). There is

battery (14) inside the handle (13) to facilitate the power supply to the micro-motor (6). A

motor switch (15) is set on the handle (13) to facilitate the control of micro-motor (6). In

order to connect the battery (14), motor switch (15) and micro-motor (6), the battery (14)

and motor switch (15) are electrically connected with the micro-motor (6).

To further optimize the scheme, set a spring (16) between the sleeve rod (12) and rod (1).

Make it sheath at outside of fixed rod (11) to keep the sleeve rod (12) and rod (1) stable,

without shaking left and right.

As a further optimization scheme, the inner net (3) is movably connected with the outer

net (4) by a zipper to facilitate the disassembly of them.

When using, zip the inner net (3) and the outer net (4) up and catch the branches with

more flowers together with fruit branches into the inner net (3), then start the micro

motor (6). The helical gear (7) drives the body of helical gear (8) to rotate, the eccentric

columns (9) drives the link rod (10), the link rod (10) drives the fixed rod (11), the fixed

rod (11) drives the sleeve rod (12), and the sleeve rod (12) drives the metal net ring (2) to

do telescopic reciprocating movement, shaking the jujube branches and fruit branches, so

as to shake the thrips on jujube flowers and some jujube flowers into the inner net (3).

Take the branches and fruit branches out and repeat above steps for 3-5 times. Then start

micro-motor (6) to make the inner net shake up and down to make the thrips drop from the inner net (3) into the outer net (4), meanwhile, filter out jujube flowers and some impurities. Remove the outer net (3) and collect thrips with a suction trap. Transfer thrips to the nucleic acid protection solution for low-temperature storage waiting for subsequent high-throughput sequencing analysis.
