Provided is an agricultural insecticide device comprising a connecting rod (1), a hydraulic rod (2), a hydraulic pump (3), a power converter (4), a main controller (5), a storage battery (6), a lift key (7), a signal sensor (8), a drive wheel (9), a solar panel (10), a photometric sensor (11), a shade plate (12), a trap lamp (13), a high voltage grid (14), an insect receiving plate (15), a lampshade (16) and a column (17). The trap lamp (13) is arranged on one side of the column (17), and is connected to the column (17) through the connecting rod (1). The lampshade (16) is arranged on the trap lamp (13) and the high-voltage power grid (14) is arranged on the lampshade (16). The insect receiving plate (15) is arranged at the lower end of the lampshade (16). The shade plate (12) is arranged at an upper end of the trap lamp (13). The storage battery (6) and the main controller (5) are arranged in the column (17). The photometric sensor (11) is arranged on the connecting rod (1), and is connected to the main controller (5). The main controller (5) is connected to the storage battery (6), and the storage battery (6) is connected to the trap lamp (13). When the photometric sensor (11) senses the darkening of the sky, this information is transmitted to the main controller (5), which controls the storage battery (6) to turn on the trap lamp (13) so as to initiate trapping insects, which reduces labor intensity.
A: Disclosed in the present invention is an intelligent theft-proof solar energy insect killer comprises a base, a bracket, a lamp bracket, a light wave resonance insect trap lamp, an insect collector, a power control box and a solar energy collecting plate. The base is mounted with a door magnetic detector. The power control box and the solar energy collecting plate are fixed on the bracket through a dismantling-proof screw. A control circuit board and a storage battery are mounted in the power control box. An automatic camera and a human body scanner are installed on the front cover of the power control box. The solar energy collecting plate, the storage battery, the door magnetic detector and an intelligent alarm are electrically connected with control circuit board respectively. The control circuit board is provided with a CPU and an RS232 data interface connected with an alarm main machine. Since the intelligent theft-proof solar energy insect killer is mounted with the dismantling-proof screw, the door magnetic detector, the automatic camera, the human body scanner and an RS232 data interface, it can guarantee safety, enhance theft-proof effect of the killer and can also be used for an alarm machine to monitor and collect evidence.
B: A smart sanitation rubbish bin, an inner bin (11) being arranged inside the bin body (4), a cover (2) being arranged at the upper end of the bin body, the cover being hinged onto the bin body, a tempered glass layer (7) being arranged on the bin body, an LED light group (5) and an acousto-optic sensor (6) being arranged in the tempered glass layer, a main controller (9) and a storage battery group (8) being arranged between the bin body and the inner bin, the acousto-optic sensor being connected to the main controller, the main controller being connected to the storage battery group, and the storage battery group being connected to the LED light group. When sensing information, the acousto-optic sensor in the tempered glass layer conveys said information to the main controller, and the main controller controls the storage battery group to drive the LED light group to illuminate, facilitating people throwing rubbish into the rubbish bin, protecting the environment, and reducing the workload of sanitation workers.
C: A seed soaking apparatus, comprising: a hot water tank (9) installed at the right side of a seed soaking tank (14). A heating disc (10) is provided inside the hot water tank (9). The hot water tank (9) is connected to an inlet hole (6) by a hot water pipe (5). A hot water pump (8) is installed on the hot water pipe (5). A support (23) is provided at the bottom end of the seed soaking tank (14). A motor (7) is installed at the top end of the seed soaking tank (14) and connected to an axle (25). A mixing blade (26) is provided on the axle (25). A main control panel (18) having therein a main controller (16) is provided on the seed soaking tank (14). A temperature sensor (20) is provided in the seed soaking tank (14) and is connected to the master controller (16), and the master controller (16) is linked to the water pump (8). The temperature in the seed soaking tank (14) is measured by the temperature sensor (20). When the temperature is too high, information thereof is transmitted to the main controller (16), and the main controller (16) controls the pumping by the hot water pump (8) of hot water from the hot water tank (9) into the seed soaking tank (14), ensuring the effectiveness of seed soaking.
D: A pressure tank having high safety performance, an electric motor (6) being provided at the upper end of a tank body (3), a rotary shaft (7) being provided in the tank body (3), a stirring device (8) being provided on the rotary shaft (7), brackets (11) being provided at the lower end of the tank body (3), a water inlet (10) being provided on one side of the tank body (3), a water outlet (14) being provided on the other side of the tank body (3), a sewage outlet (12) being provided at the lower end of the tank body (3), a water discharge controller (13) being provided at the water outlet (14), a balance sensor (9) being provided in the tank body (3), a main controller (15) being provided on the tank body (3), the balance sensor (9) being connected to the main controller (15), and the main controller (15) being connected to the water discharge controller (13). When the tank body (3) is collided, the balance sensor (9) in the tank body (3) senses a signal of losing balance and will pass the information to the main controller (15), and the main controller (15) will control the water discharge controller (13) to discharge water so as to reduce the pressure in the tank body (3).
