Description

Technical Field

[0001] The invention relates to the technical field of insect breeding, in particular to an anti-escape device for insect breeding. Background Art

[0002] Compared with traditional animal farming, insect farming has the characteristics of small size, strong flying or jumping ability, hiding during the day and coming out at night, and easy escape. Many insects are pests themselves. Once they escape, they will not only cause economic losses to the farmers, but also affect the ecological balance.

[0003] According to Chinese patent application No. 202022337443.3, an anti-escape device for insect breeding includes a shell, the inner wall of the shell is fixedly connected to the outer side of a clamping block near the rear side, the back side of the clamping block clamps the front end of a small ball rod, the rear end of the small ball rod is fixedly connected to the front side of a positioning block, and the inner side of the positioning block is fixedly connected to the left and right sides of a fixed frame. When the anti-escape device is in use, when an insect crawls onto the first isolation net, the motor starts to drive the cam to rotate and continuously hit the vibration block, causing the vibration frame to vibrate at a certain frequency, which can effectively make the insects crawling on the first isolation net fly away or fall off by vibration, and can effectively solve the problem of poor air intake at the air inlet when the insect crawls on it or dies;

[0004] However, the above-mentioned anti-escape device for insect breeding still has the following shortcomings:

[0005] 1. The anti-escape equipment in the insect breeding cabin is single, there is no additional anti-escape measures for personnel entrances and exits, and anti-escape equipment is not set inside and outside the cabin, making it impossible for the breeding cabin to effectively and comprehensively prevent the escape of insects;

[0006] 2. The vibration of the isolation net needs to be driven by a separate motor, which increases the investment cost of the equipment.

[0007] To this end, we designed an anti-escape device for insect breeding. Summary of the invention

[0008] 1. Technical issues to be resolved

[0009] In view of the shortcomings of the prior art, the present invention provides an anti-escape device for insect breeding, which effectively prevents the problem of insect escape during the insect breeding process and reduces the cost of insect escape equipment.

[0010] (II) Technical solution

[0014] The driving mechanism includes a rotating shaft vertically arranged in the ventilation duct, and the upper and lower ends of the rotating shaft are connected to the top and bottom of the ventilation duct through ratchets; a driven bevel gear is provided in the middle of the rotating shaft, and an active bevel gear is provided at the end of the fan transmission shaft, and the active bevel gear and the driven bevel gear are meshed for transmission; a driving block is provided at the upper and lower parts of the rotating shaft, and when the rotating shaft rotates, the driving block rotates accordingly, and the driving block will drive the side of the extension tube when rotating, so that the extension tube moves outward under the pressure of the raised part of the driving block, and the spring stretches at this time. When the raised part of the driving block passes over the side of the extension tube, the extension tube rebounds quickly under the tension of the spring, thereby causing the ventilation tube cover to shake.

[0015] The driving block is in the shape of a letter "6" with a through hole in the middle for connection to the rotating shaft. The outer peripheral surface of the driving block is rounded to facilitate contact between the driving block and the side of the extension tube.

[0016] The tooth groove surface of the active bevel gear is arranged with tooth grooves at intervals. When the fan transmission shaft drives the active bevel gear to rotate, the active bevel gear intermittently meshes with the driven bevel gear, and the rotating shaft follows its intermittent rotation. At the same time, due to the setting of the ratchet, the rotating shaft will not rotate in the intermittent section.

[0017] The water curtain mechanism includes a plurality of water curtain nozzles arranged on the upper wall of the inlet and outlet channel and a water tank arranged on the upper end outside the inlet and outlet channel, the water tank and the water curtain nozzles are connected through a water pipe; the plurality of water curtain nozzles are arranged in a straight line, and their width is consistent with the width of the inlet and outlet channel; a water pump is arranged on one side of the inlet and outlet channel, the water inlet of the water pump is connected to the anti-escape water channel through a water pipe, and the water outlet is connected to the water tank through a water pipe; when in use, water is pumped into the water tank through the water pump, and the water flows out through the water curtain nozzles to form a water curtain shape to prevent insects from flying out, and the water sprayed from the water curtain nozzles will enter the anti-escape water channel again for recycling.

[0018] Partitions are provided on all sides of the interior of the breeding cabin near the cabin body, and adjacent partitions are connected and fixed by partition fixing columns; through holes are provided on the upper and lower parts of the partitions, and an anti-climbing plate is provided in the middle part of the partition, and the anti-climbing plate is made of a smooth metal plate or a glass plate; it is used to isolate insects and prevent them from crawling around.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides an anti-escape device for insect breeding, which has the following beneficial effects:

[0022] 1. The anti-escape device for insect breeding can prevent the staff from taking the insects out of the breeding cabin by setting a water curtain mechanism and a double-layer closed door at the entrance and exit of the breeding cabin; and an anti-escape water channel is set on the periphery of the breeding cabin.

[0023] 2. The anti-escape device for insect breeding is provided with a ventilation duct cover inside the ventilation duct of the breeding cabin, and a fan is provided in the ventilation duct. The fan drives the driving mechanism to intermittently shake the ventilation duct cover, thereby driving away the insects crawling on the ventilation duct cover. There is no need to provide a separate motor to drive the ventilation duct cover to shake. On the one hand, it prevents insects from escaping from the ventilation duct opening and reduces the blockage of the ventilation duct due to insect accumulation. On the other hand, it reduces the investment cost of the equipment.

[0024] 3. The anti-escape device for insect breeding has partitions arranged on all sides of the breeding cabin near the cabin body, and an anti-climbing plate is arranged in the middle of the partition. The anti-climbing plate is made of a smooth metal plate or a glass plate, which can effectively isolate the insects and prevent the insects from crawling around.
