Technical Field

The invention relates to the field of fruit fly capture, in particular to a fruit fly capture device provided with an attractant and a use method thereof.

Background technique

Fruit flies are a type of saprophytic pest. Under natural conditions, they mostly feed on corrupted food such as rotten fruits and vegetables. In recent years, with the investigation and development of the planting industry, the damage caused by fruit flies in production has become more and more serious. In the past, fruit farmers would use the method of spraying pesticides, but large-scale spraying of pesticides will seriously contaminate the fruit and affect human health. Therefore, the use of pollution-free prevention and control technology has become a key measure to control the damage of fruit flies in orchards.

Fruit flies are generally controlled by using attractants. For example, the invention patent with publication number CN104938460B discloses a fruit fly catching device with a fast-attracting fermented fruit attractant, which can trap adult fruit flies in the device and kill the fruit flies through the fruit fly attractant.

However, the current capture devices that use traps to kill fruit flies have certain disadvantages: long-term trapping will cause fruit fly corpses to accumulate in the traps, affecting subsequent trapping work for a long time.

The invention patent with publication number CN112005983A discloses a fruit fly trapping device, which uses an attractant to attract fruit flies along a first constricted tube into a lower bottle body to trap the fruit flies. The lower bottle body, the upper bottle body and the bottle cap are threadedly fixed in sequence and can be separated in pairs to facilitate the discharge of fruit flies and the replacement of the attractant. However, this application discharges the fruit fly corpses manually, and there is currently no capture device that can automatically discharge the fruit fly corpses in the attractant.

Detailed ways

The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

As shown in Figures 1-8, the present invention is a fruit fly catching device equipped with an attractant, including an outer cover barrel 1 with upper and lower openings, an attractant box 7 fixedly connected to the outer cover barrel 1, and a cylinder 8 fixedly connected below the attractant box 7, wherein the attractant box 7 is filled with the attractant.

The outer cover barrel 1 is a round barrel, with an opening at the upper end to facilitate the entry of fruit flies and an opening at the lower end to facilitate the falling and discharge of fruit fly corpses. A mounting frame 5 is fixedly connected to the side of the outer cover barrel 1 to achieve fixed installation of the capture device. A rain cover 2 is fixedly connected to the top of the outer cover barrel 1, and the rain cover 2 is connected to the outer cover barrel 1 through an outer cover support rod 4. A solar panel 3 is installed on the rain cover 2, and a battery 6 is installed in the outer cover barrel 1, thereby realizing photovoltaic power generation and providing electrical energy for the entire capture device without the need for an external power supply.

The trap box 7 is a transparent box, and an LED lamp 15 is installed at the bottom of the trap box 7, so as to utilize the phototaxis of fruit flies. When the fruit flies move from top to bottom toward the LED lamp 15, they will fall into the trap box 7, thereby improving the trapping effect.

It also includes a discharge pipe 9 that vertically passes through the attractant box 7 and the cylinder body 8. The discharge pipe 9 is provided with sealing rings at the places where it passes through the attractant box 7 and the cylinder body 8 to improve the sealing effect at the passing place. When the fruit flies are normally captured and killed, the discharge pipe 9 moves up to the upper end so that the upper end opening is higher than the liquid level of the attractant, thereby blocking the passing hole and preventing the attractant from flowing down.

An outer rib 19 is fixedly connected to the upper end of the discharge pipe 9. When the discharge pipe 9 moves downward and the outer rib 19 moves to the bottom of the trap box 7, the discharge pipe 9 cannot move further downward. The bottom of the trap box 7 is provided with a sink groove for accommodating the outer rib 19. When the outer rib 19 moves to the bottom of the trap box 7, it falls into the sink groove, thereby facilitating all the trapping agents in the trap box 7 to flow into the discharge pipe 9.

The discharge pipe 9 passes through the center position of the bait box 7. The bottom of the bait box 7 is a conical surface, so that the discharge pipe 9 passes through the lowest point of the bait box 7. The upper end surface of the bottom of the bait box 7 is fixedly connected with a plurality of guide plates 16 arranged along the circumferential direction. The angle between the guide plates 16 and the radial direction of the bait box 7 is 30 to 60 degrees. When the bait in the bait box 7 flows into the discharge pipe 9, the guide effect of the guide plates 16 causes the bait to generate a rotating vortex. The fruit fly corpses are concentrated in the center position under the action of the vortex, which facilitates the fruit fly corpses to enter the discharge pipe 9.

The cylinder 8 is a cylindrical body with an opening at the lower end. The discharge pipe 9 passes through the upper top plate of the cylinder 8. The lower end of the outer ring of the discharge pipe 9 is fixedly connected with a piston plate 11 that fits the inner wall of the cylinder 8. The discharge pipe 9, the cylinder 8 and the piston plate 11 constitute a closed liquid storage chamber. When the piston plate 11 moves up and down following the discharge pipe 9, the volume of the liquid storage chamber changes. The upper end of the liquid storage chamber is connected to the upper end of the trap box 7 through the reflux pipe 14. The reflux pipe 14 is connected to the upper side of the liquid level in the trap box 7. When the volume of the liquid storage chamber increases, the reflux pipe 14 plays the role of suction; when the volume of the liquid storage chamber decreases, the trap in the liquid storage chamber is pressed into the trap box 7 through the reflux pipe 14.

A piston 10 is vertically slidably connected in the discharge pipe 9 , and the piston 10 can move downward to be drawn out from the discharge pipe 9 . The upper end surface of the piston 10 is a conical surface, so that the fruit flies above the piston 10 can slide off when the piston 10 is drawn out from the discharge pipe 9 .

A limit block 26 located above the piston 10 is fixedly connected to the inner wall of the discharge pipe 9 , and the piston 10 moves upward and presses against the limit block 26 , thereby driving the discharge pipe 9 to move upward.

A filter hole 17 is provided on the side of the discharge pipe 9. When the piston 10 moves upward to the limit block 26, the filter hole 17 is blocked by the side of the piston 10. When the outer retaining edge 19 moves downward to the bottom of the attractant box 7, the filter hole 17 is connected with the upper end of the liquid storage chamber. When the piston 10 moves downward relative to the discharge pipe 9, the piston 10 leaves the filter hole 17, so that the attractant in the discharge pipe 9 flows into the liquid storage chamber through the filter hole.

The diameter of the filter hole 17 is smaller than the volume of the fruit fly to prevent the fruit fly from passing through. There are multiple filter holes 17 arranged along the circumference. The inner wall of the discharge pipe 9 is provided with an annular groove 18. The filter hole 17 is arranged in the annular groove 18, so that all the filter holes 17 are connected through the annular groove 18 to facilitate the outflow of the attractant.

The piston 10 is fixedly connected to a vertical driving rod 12 at the lower end thereof, and further comprises a tension spring 13 for driving the discharge pipe 9 to move downward and a driving mechanism for driving the driving rod 12 to move up and down. The piston 10 is driven to move up and down by the driving rod 12 to move up and down.

The driving mechanism includes a guide sleeve 20 fixed to the center of the lower end of the cylinder body 8 and a passive gear 21 axially connected to the lower end of the guide sleeve 20 . Since the lower end of the cylinder body 8 is open, the guide sleeve 20 is fixed by a plurality of guide sleeve connecting rods 25 .

The driving rod 12 is vertically slidably connected in the guide sleeve 20. In order to achieve the sliding connection of the driving rod 12, two parallel limiting surfaces are provided on the side of the driving rod 12, and a guiding surface that fits with the limiting surface is provided in the guide sleeve 20.

The driving rod 12 is provided with an external thread, and the center of the passive gear 21 is provided with an internal thread. The driving rod 12 is threadedly connected with the passive gear 21. The driving mechanism also includes a motor 23 and a driving gear 22 installed on the motor 23. The driving gear 22 is meshed with the passive gear 21, and the motor 23 is fixedly connected to the guide sleeve connecting rod 25.

The upper end of the tension spring 13 is connected to the piston plate 11 , and the lower end is connected to the guide sleeve connecting rod 25 .

A method for using a fruit fly catching device comprises the following steps: a. catching and killing fruit flies by using the attractant in the attractant box 7, at which time the piston 10 is driven upward by the driving rod 12, and the piston 10 drives the discharge pipe 9 upward through the limit block 26, so that the upper end surface of the discharge pipe 9 is higher than the liquid level of the attractant, and the state at this time is as shown in FIG2;

b. When a certain number of fruit flies accumulate in the trapping agent box 7, the fruit flies are cleaned up regularly; c. When cleaning, the driving rod 12 drives the piston 10 to move downward, and the discharge pipe 9 moves downward along with the piston 10 through the downward pull of the tension spring 13;

d. When the outer retaining edge 19 of the discharge pipe 9 moves down to the bottom of the trap box 7, the discharge pipe 9 stops moving down, and the state at this time is shown in Figure 3; the piston 10 continues to move down so that the filter hole 17 on the side of the discharge pipe 9 is connected with the upper end of the liquid storage chamber. At this time, the upper end surface of the piston 10 is flush with the lower end of the filter hole 17. The piston is stationary for 1 to 10 minutes, so that the trap in the trap box 7 flows from the upper end of the discharge pipe 9 into the discharge pipe 9 and flows into the liquid storage chamber through the filter hole 17. At this time, the fruit flies remain in the discharge pipe 9, and the state at this time is shown in Figure 4;

e. The piston 10 continues to move downward and is drawn out from the lower end of the discharge pipe 9, so that the fruit flies in the discharge pipe 9 are discharged from the lower end of the discharge pipe 9. At this time, the state is shown in Figure 5;

f. After the fruit flies are discharged, the piston 10 moves up to the limit block 26 and blocks the filter hole 17, driving the discharge pipe 9 to move up through the limit block 26. At this time, the volume of the liquid storage chamber becomes smaller, and the attractant in the liquid storage chamber is pressed into the attractant box 7 through the reflux pipe 14, thereby continuing to capture and kill.
