Description

A manual wind sucker

technical field

The utility model belongs to the technical field of small-scale agricultural plant protection appliances, in particular to a manual wind-powered insect sucker.

Background technique

With the development of organic agriculture, physical or mechanical insecticide methods have gradually attracted people's attention, and more and more manual, electric or motorized insect extractors have begun to be used. The existing manual insect extractors have low efficiency and are only suitable for experiments. Research work, while electric or motorized insect flukes are difficult to promote in small-scale production that is still dominated by family operations in my country at present due to their high cost. Therefore, existing manual insect extractors have the disadvantages of low insect extraction efficiency and high cost of electric or motorized insect extractors, making it difficult to popularize in small-scale production.

Contents of the invention

The purpose of the utility model is to solve the technical problems that the existing manual insect sucker has low efficiency of sucking insects and the electric or motorized insect sucker has high cost and is difficult to popularize in small-scale production, and provides a manual wind-powered insect sucker.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A manual wind-powered insect sucker, including a suction pipe, a variable-diameter tee joint, a suction cup and an insect collecting bottle, wherein: it also includes a bellows composed of a box, a piston and a piston rod, a filter screen, two unidirectional air intakes Valve and two one-way air outlet valves, the piston is set in the box and divides the box into two left and right air chambers, each air chamber is equipped with a one-way air inlet valve and a one-way air outlet valve, one end of the piston rod is connected to the The piston is connected, the other end of the piston rod is provided with a handle, the air inlet of the one-way air intake valve is connected with the air outlet of the suction pipe, and the air inlet of the suction pipe is connected with a horizontal port of the variable diameter tee joint. Another horizontal port of the diameter tee joint is connected with the sucker, the inner chamber of the variable diameter tee joint is provided with a filter screen, and the third port of the variable diameter tee joint is connected with the insect collecting bottle and the insect collecting bottle can be loaded and unloaded.

The two ends of the bellows are provided with straps, and the suction cup is provided with protective nets.

The utility model adopts the above technical scheme, which solves the technical problems that the existing manual insect sucker has low efficiency of sucking insects and the electric or motorized insect sucker has high cost and is difficult to popularize in small-scale production. Therefore, compared with the background technology, the utility model has the following advantages:

1) The utility model adopts the double movement mode of the piston, which can work no matter it is pushing or pulling, and at the same time uses the blowing force to disturb and directional drive away the insects, thereby improving the work efficiency and the insect removal effect;

2) The utility model has the advantages of simple structure, low cost, convenient operation and easy popularization and application;

3) The utility model does not consume any energy and is non-polluting; when operating, only push and pull when seeing bugs, which is economical and efficient;

4) The utility model is suitable for sucking and killing small insects such as Bemisia tabaci and aphids.

Detailed ways

As shown in Fig. 1 and Fig. 2, a kind of manual air insect sucker in the present embodiment comprises air suction pipe 2, variable diameter tee joint 3, suction cup 5 and insect collecting bottle 7, wherein: it also includes box body 12. A bellows composed of piston 9 and piston rod 11, a filter screen 4, two one-way air intake valves 14 and two one-way air outlet valves 10, the piston 9 is arranged in the box body 12 and the box body 12 is divided into left and right two Each air chamber is provided with a one-way air inlet valve 14 and a one-way air outlet valve 10 and the one-way air inlet valve 14 and the one-way air outlet valve 10 are vertically arranged at the end of the air chamber, and the piston rod 11 One end is connected with the piston 9, the other end of the piston rod 11 is provided with a handle, the air inlet of the one-way air inlet valve 14 is connected with the air outlet of the suction pipe 2, and the air inlet of the air suction pipe 2 is connected with the reducing tee joint 3 is connected to one horizontal port, and the other horizontal port of the variable diameter tee joint 3 is connected to the suction cup 5. The inner chamber of the variable diameter tee joint 3 is provided with a 20-30 mesh filter screen 4, and the third port of the variable diameter tee joint 3 Three ports are connected with insect collecting bottle 7 and make collecting insect bottle 7 loadable and unloadable, the two ends of bellows are provided with strap 1, and suction cup 5 is provided with thick hole protective net 6.

The working principle of the utility model is: when working, put the shoulder strap on the shoulder, grasp the suction pipe and the handle with one hand, and grasp the handle of the piston rod with the other hand, push and pull the piston to do reciprocating motion in the box, and the suction cup is in a negative pressure state, thus Aspirate flying insects into the aspiration tube. At the same time, the outlets of the two one-way air outlet valves also generate continuous blowing, which blows up the small insects lying on the plants and helps the suckers to suck them in. The insects sucked into the suction pipe fall into the insect collecting bottle under the blocking of the filter screen and are concentratedly killed.
