Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vegetable pest control, in particular to a vegetable pest control device. BACKGROUND

[0002] Vegetable greenhouse is a facility for planting vegetables, usually composed of metal or plastic frame, covering material, ventilation equipment, irrigation system, etc., which can provide suitable growing environment for vegetables, prolong the growing season of vegetables, and improve yield and quality. Pest control is usually needed in vegetable greenhouse.

[0003] The effective range of the trap lamp is usually 30-50 meters. In order to ensure sufficient effective range, the trap lamp is usually hung at a high position. However, the farther the position from the lamp, the more serious the shielding by vegetables, especially at low positions.

[0004] To this end, Chinese patent application No. CN202420540888.7 discloses a vegetable greenhouse pest control device. The device mainly sets up a lifting moving structure. When the driving motor is started, the two shaft rods are reversely rotated under the rotation of the first bevel gear and the second bevel gear, thereby driving the two bevel gears to rise and fall on the first and second helical racks under the action of the transmission belt, so that the lifting platform and the trap lamp body as a whole move up and down, to a certain extent, ensuring that the trap lamp body can kill pests at different heights.

[0005] However, the present inventors found that the above-mentioned technology at least has the following technical problems in the process of implementing the technical solutions in the embodiments of the present application:

[0006] When the trap lamp is at a low position, the effective range will be sharply reduced due to the shielding of vegetables, affecting the trapping effect. If the pest control effect is to be ensured, more lifting moving structures and trap lamps need to be set up, which occupies a large space. CONTENT OF THE UTILITY MODEL

[0007] In order to make up for the above shortcomings, the present application provides a vegetable pest control device, which aims to improve the problems mentioned in the above background technology.

[0008] The present application provides a vegetable pest control device, which includes a suspension mechanism, a moving mechanism and a trap lamp. The trap lamp is installed on the moving mechanism. The suspension mechanism includes at least two electrified suspension cables. The moving mechanism moves along the two suspension cables. The moving mechanism is provided with an electricity leading mechanism. The electricity leading mechanism supplies power to the moving mechanism and the trap lamp after taking power from the two suspension cables. The moving mechanism is also provided with a U-turn mechanism. The U-turn mechanism triggers the moving mechanism to move reversely after collision.

[0009] In a specific embodiment, the suspension mechanism further comprises a column fixed on the ground and a pull seat fixedly connected with the column, and the suspension cable is fixedly connected with the pull seat.

[0010] In the implementation process, the column is fixed on the ground, the pull seat is fixed at the top end of the column, the pull seat comprises two insulation heads for fixing two suspension cables respectively, 220V mains power is converted into 24V DC through a step-down rectifier module, and the positive and negative poles are delivered to the two suspension cables respectively.

[0011] In a specific embodiment, the moving mechanism comprises an upper shell and a lower shell, the upper shell is bolted with the lower shell, and the upper shell and the lower shell are provided with pulleys.

[0012] In the implementation process, the upper shell and the lower shell are folded, so that the eight pulleys are clamped on the suspension cable and roll, which has certain wind resistance and is beneficial to outdoor use.

[0013] In a specific embodiment, the upper shell is provided with a rain cover at both ends, and the front edge of the rain cover is slidingly connected with the upper surface of the suspension cable.

[0014] In the implementation process, the rain cover is used to improve the rainproof effect, and the front end of the rain cover is wedge-shaped, which is beneficial to scraping off the leaves and other foreign matters on the suspension cable, so as to avoid the influence of foreign matters on the rolling of the pulley.

[0015] In a specific embodiment, the moving mechanism further comprises a rotating shaft, a bracket and a motor, the pulleys on both sides are fixedly connected through the rotating shaft, the bracket is fixedly connected with the inner wall of the upper shell, the motor is installed on the bracket, and the output end of the motor is power connected with the rotating shaft.

[0016] In the implementation process, the motor drives the rotating shaft to rotate, so as to drive the pulley to roll. The pulley is made of nylon material and has anti-skid lines on the surface, which can reduce the slip between the pulley and the suspension cable. In this embodiment, the suspension cable has a double-layer structure, the middle part is a reinforcing rib made of glass fiber reinforced plastic for bearing tensile capacity, and the outer layer is a plurality of copper-magnesium alloy wires wound on the reinforcing rib for power transmission. The copper-magnesium alloy has a conductivity of 65%-95% IACS and a resistivity of 1.72×10⁻ 8 ~2.00×10⁻ 8 Ω·m, which can meet the low-voltage power supply requirement. When necessary, the copper-magnesium alloy surface can be tinned to improve corrosion resistance.

[0017] In a specific embodiment, the moving mechanism further includes a bevel gear, and the bevel gear is provided on both output ends of the rotating shaft and the motor. The two output ends of the motor drive the two rotating shafts to rotate synchronously through the engagement of the bevel gears.

[0018] In the above implementation process, the motor adopts a double-headed reduction motor, each head drives the shaft to rotate through a pair of bevel gears, thereby synchronously driving the four pulleys to rotate.

[0019] In a specific embodiment, the power-inducing mechanism includes a spring sheet and a carbon slide plate. The carbon slide plate is elastically connected to the bracket via the spring sheet, and the carbon slide plate is slidingly and frictionally connected to the suspension cable.

[0020] In the above implementation process, the carbon slide contacts the suspension cable to obtain electrical energy. The shrapnel is made of copper to ensure that the carbon slide is pressed against the suspension cable and conducts electricity. The obtained 24V DC power is used to power the insect trap lamp. If a 220V insect trap lamp is used, an inverter is required.

[0021] In a specific embodiment, the U-turn mechanism includes a sensor and a push rod, the push rod is axially slidably connected to the bracket, the sensor is installed on the bracket, the sensing end of the sensor abuts against the push rod, and the front end of the push rod abuts against another push rod.

[0022] In the above implementation process, when multiple insect-attracting lamps move on the suspension cable, if they collide in opposite directions, the two top rods will collide with each other, or the top rods will hit the pull seat, thereby triggering the sensor. The sensor switches the rotation direction of the motor through the motor control circuit, thereby realizing the U-turn function. The motor's commutation control circuit is a conventional technology and can be purchased directly, so it will not be repeated here.

[0023] In a specific embodiment, the push rod is slidingly connected to the bracket, a hump block is fixedly connected to the push rod, a roller is provided on the sensing end of the sensor, the hump block has a double hump structure, the roller is located between the double humps, and a limiting ring is provided on the push rod to abut against the bracket.

[0024] In the above implementation process, the sensor is a limit switch, and its sensing end has a reset function. A seesaw is hingedly connected, and the seesaw rests on the sensing end. A roller is provided at the front end of the seesaw, and the roller is placed inside the two humps of the hump block. When the push rod moves in any direction, it will push the trigger sensor, thereby changing the moving direction of the insect attractant lamp. The moving range of the push rod is limited by the limit ring, thereby ensuring that the roller is always within the constraint of the hump block. In this embodiment, the hump block is stuck on the push rod and fixed by screws, which facilitates the loading and unloading of the hump block. One side of the hump block slides against the surface of the bracket to ensure that the hump block does not rotate with the push rod.

[0025] In a specific embodiment, the top rod is provided with a top head at both ends, the top head is located outside the rain cover, the top rod is provided with a rainproof ring, and the rainproof ring is located inside the rain cover.

[0026] In the above implementation process, the top head is made of nylon material to reduce collision noise. Since the suspension cable is in the shape of a parabola, the top rod is mostly inclined. Therefore, when it rains, the rainproof ring can prevent rainwater from flowing along the top rod into the upper shell and the lower shell, thereby avoiding the influence of rainwater on the internal structure.

[0027] Compared with the prior art, the beneficial effects of the present application are that the moving mechanism can be hung on the suspension cable to increase the range of attracting insects; multiple moving mechanisms can be hung on the suspension cable, and adjacent moving mechanisms can trigger the moving mechanism to reverse through the turning mechanism when colliding, thereby realizing turning and automatic reciprocating movement of the moving mechanism, and reducing space occupation; the electricity induction mechanism can absorb electric energy from two suspension cables to supply the moving mechanism and the insect attracting lamp, and there is no endurance problem.
