Description

Monitoring devices is traped to pest in granary

Technical Field

The invention relates to the field of grain storage, in particular to a device for monitoring and trapping the quantity of pests in a warehouse.

Background

China is a large population country, a large food production country and a large food storage country. In the process of grain storage, the annual grain loss of China is about 0.2 to 0.5 percent of the total amount of stored grain, wherein the loss caused by the damage of grain storage pests is about 50 percent. Therefore, in order to effectively reduce the loss caused by grain storage pests, grain pest control becomes a key technical problem of grain safety guarantee in China, and detection and identification of grain pests become a primary link and a key problem of grain pest control.

Traps are an effective way to trap pests in stored grain. Generally, by studying the life habit characteristics of pests, such as phototaxis, climbing and the like, the most comfortable living environment for the pests is arranged in the trap to attract the pests to climb into the inside of the trap body, so as to achieve the trapping purpose. For example, the ultraviolet light trap and the black light trap, the electric trap is a method for trapping on the surface of grains by utilizing the phototaxis characteristic of the grain insects, but the method only can attract phototaxis grain insects, mainly traps moth-like grain insects and has no effect on the phototaxis grain insects. Still other traps can be inserted into the interior of the grain to trap but cannot trap pests on the surface of the grain. And the light of the pest trap is basically shielded by surrounding grain particles, so that the light emitting range of the pest trap is very small, the pest trap can only play a limited role in a small range, and the trapping capability is insufficient.

In practical use, the existing trap is single in structural design function, and the trapping effect of pests in the grain pile or pests on the surface of the grain pile is good. In addition, in the aspect of pest counting, a mechanical structure is generally adopted to count pests entering the trap, and the method has low action precision.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in figures 1 and 2, the invention provides a pest trapping and monitoring device in a granary, which is integrally in an inverted funnel shape and comprises a base 1, a shell 2, a support rod 6 and a shell cap 7, wherein the shell 2 is coaxially fixed on the disc-shaped base 1, the hollow support rod 6 is coaxially fixed on the upper part of the base 1 and extends out of the shell 2 from an opening at the upper end of the shell 2, and the shell cap 7 is coaxially fixed at the upper end of the hollow support rod 6 and covers a round hole at the upper end of the shell 2.

The upper part of the shell 2 is provided with a plurality of rows of insect attracting holes 11, the insect attracting holes 11 are between the grain and the insect size, and can be arranged according to the grain and the insect type in the grain depot to prevent the grain from entering the trap, and the typical value is 2 x 2 mm.

The outer surfaces of the shell 2 and the shell cap 7 are inverted conical, and a gap through which pests can pass is reserved between the outer surface of the shell 2 and the inner surface of the shell cap 7; the pests at the upper part of the pest trapping holes 11 continuously climb up through the slope of the shell 2 and enter the interior of the trapping device through the upper opening of the shell 2. The opening of the upper part of the shell 2 is provided with a downward first tapered slope 12, the bottom of the first tapered slope 12 is close to the support rod 6, and pests slide to the inside of the device along the first tapered slope 12 to achieve the trapping effect. Inside the shell 2, the lower part of the pest trapping hole 11 is provided with a second conical slope 10, and pests slide to the bottom along the second conical slope 10 after entering the shell 2 from the pest trapping hole 11, so that the function of collecting the pests is achieved.

Preferably, in one embodiment of the present invention, the hollow support rod 6 is internally provided with the LED wick 5, and the housing 2, the support rod 6 and the housing cap 7 are made of transparent or translucent materials, so as to attract pests to enter the device by utilizing the phototaxis characteristic of pests. In another embodiment of the present invention, pheromones are coated on the surface of the support rod 6 to enhance the attraction effect.

Preferably, an electric motor 3 and a fan 4 are installed near the bottom of the support bar 6 to accelerate the air flow, further enhancing the pheromone attraction effect.

Preferably, a counting sensor 14 is installed at the lower portion of the second tapered ramp 10 to count pests entering the bottom of the device. When the accumulated times exceed a set value, the device transmits a signal to monitoring personnel, and then the monitoring personnel perform subsequent processing according to the collected information.

In order to enhance the blocking effect, a circle of insect-proof adhesive tape 9 is arranged at the joint of the support rod 6 and the base 1 and at the lower part of the insect trapping hole 11 in the shell 2.

The electric motor 3, the LED lamp wick 5 and the counting sensor 14 are all powered by the rechargeable power supply 8.

The shell 2 is conical, and the life habit that pests climb up can be fully utilized. Meanwhile, after the device is placed into a grain pile, the inclined design can increase the contact area between the trap and the grain pile and increase the probability of trapping pests. In addition, the outer surface of the shell 2 is inclined, the inner surface of the shell can also be inclined, the included angle between the inner surface of the shell and the horizontal plane is 180 degrees, when pests climb into the trapping device from the outside, the pests are easy to climb out, and when the pests want to climb out of the device, the inclined plane and the horizontal plane form an acute angle, so that the pests are prevented from climbing out of the device.

The top of the shell 2 is covered by a shell cap 7, and when the trapping device is placed inside the grain pile, grains can be prevented from entering the device through the top opening. While leaving a space between the housing cap 7 and the housing 2 so that pests can smoothly enter the device. Since the housing 2 and the housing cap 7 are both tapered slopes, the grains do not enter the inside of the apparatus through the gap.

The working process of the invention is as follows:

lofting: the installed device is placed into a sampling point set in a grain pile, the surface and the inside of the grain pile can be both the surface and the inside of the grain pile, the grain pile is placed into the grain pile, the action principle is shown in figure 3, after the grain pile is placed into the grain pile, the grain cannot enter the device through the opening at the upper end of the shell 2 under the action of the shell cap 7, the size of the insect attracting hole 11 is smaller than that of the grain, and the grain cannot enter the device through the insect attracting hole 11.

Inducing: when inside the grain heap, LED light attracts the pest, and pheromone spreads under the effect of fan 4 simultaneously to this attracts the pest around the device to be close to the device.

Capturing: the pests 13 can enter the device through two channels, firstly, the pests 13 below the height of the pest trapping holes 11 climb up the conical slope outside the device to pass through the pest trapping holes 11 to enter the device. Secondly, the pests 13 above the height of the pest trapping holes 11 can continuously climb up through the gap between the shell cap 7 and the shell 2 and enter the device through the first conical slope 12 at the upper opening of the shell 2. The second conical slope 10 at the lower part of the insect attracting hole 11 in the shell 2 plays a role in temporarily collecting pests entering the device, the pests 13 stop the sensing signal counting sensor 14 to count once during falling, and all the pests 13 falling to the bottom of the device are counted. The sensor 14 transmits the counting information to the PC end in real time for the detection personnel to refer to.

The above embodiments are only used for illustrating the present invention, and the structure, connection mode, etc. of the components may be changed, and all equivalent changes and modifications based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
