Description

The motor-driven spraying machine of twin-tub

The utility model relates to a kind of atomising device, particularly relates to the motor-driven spraying machine of a kind of twin-tub.

Existing agricultural atomising device, as sprayer backpack, flat-crushing type and pedal, labour intensity is big, inefficiency.Because pressure is little, fogging degree is low, and range is near, when dense fruit tree is sprayed medicine, sprays inhomogeneously, does not reach the purpose of prevention and elimination of disease and pests.

The purpose of this utility model is to provide a kind of manual labor that alleviates, and increases work efficiency fogging degree height, the motor-driven spraying machine of the twin-tub of far firing range.

The purpose of this utility model is achieved in that body, suction seat, pump and the air chamber base of the motor-driven spraying machine of this twin-tub connect together by screw rod, form two soup cylinders, bent axle is housed on the body, two cover linkages are installed on the bent axle, and two groups of slide block assemblies are contained in respectively on the two cover linkages.Between body and the suction seat oil sealing is housed, oil-sealing sleeve is on the piston rod of slide block assembly, the left end of piston rod is equipped with the water intaking valve assembly, the outlet valve assembly is installed in the air chamber base, air chamber is installed on the air chamber base, air chamber base is provided with the drug discharging tube joint, and the water inlet pipe that has filter screen is connected to a return pipe that communicates with pressure regulator valve.

The water intaking valve assembly is made up of flat valve, piston cup holder, piston cup, cam sleeve and water inlet valve block, and they are contained on the piston rod of slide block assembly successively, tightens together with nut, and the water inlet valve block is provided with several apertures.The outlet valve assembly is made up of spring base, spring, flat valve and outlet valve, and spring and flat valve are packed in the spring base, install outlet valve again, and the center of outlet valve is provided with the hole, and the end of spring base and circumference also have aperture.

The utility model can be discharged more soup in moment owing to have two soup cylinders, forms higher pressure, therefore can make the fogging degree height of soup, and can reach range far away.Owing to the pressure height, can be with a plurality of shower nozzles to spray insecticide simultaneously simultaneously, high efficiency is higher more than 6 times than manual sprayer.This device can be adjusted pressure according to working condition owing to be provided with pressure regulator valve, both can avoid hypertonia, damages pipeline, can guarantee suitable pressure again, and it is atomized, and reaches required range.This device can alleviate manual labor greatly owing to driven by power.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the motor-driven spraying machine of twin-tub that the utility model proposes.

The motor-driven spraying machine of this twin-tub, body 8, suction seat 4, pump 13 connect together by screw rod 25 with air chamber base 10, form two soup cylinders.A bent axle is installed on the body 8, has installed 9, two groups of slide block assemblies 7 of two cover linkages on the bent axle and be installed in respectively on the two cover linkages 9.Between body 8 and the suction seat 4 oil sealing made from rubber 6 is housed, oil sealing 6 is enclosed within on the piston rod of slide block assembly 7, and oil sealing can avoid soup to mix with oil.The left end of piston rod is equipped with water intaking valve assembly 12, water intaking valve assembly 12 is made up of flat valve 20, piston cup holder 18, piston cup 19, cam sleeve 17 and water inlet valve block 16, they are contained on the piston rod of slide block assembly 7 successively, water inlet valve block 16 usefulness screw threads are contained on the piston rod, tighten together with nut more at last.Water inlet valve block 16 is provided with 4-6 aperture.Outlet valve assemblies 11 are installed in the air chamber base 10, and outlet valve assembly 11 is made up of spring base 21, spring 22, flat valve 23 and outlet valve 24, and spring 22 and flat valve 23 are packed in the spring base 21, load onto outlet valve 24 then.Outlet valve 24 centers are provided with a through hole, and there is a through hole at the center, rear end of spring base 21, and its circumference is provided with 2-4 aperture.The top of air chamber base 10 is equipped with air chamber 1, and the left end of air chamber base 10 is provided with 2-4 drug discharging tube joint 15, is used for connecting the sebific duct of shower nozzle.The right-hand member of air chamber base 10 is provided with a pipe joint, and manometer 5 connects thereon by tube connector 28.Filter screen 14 is equipped with in the lower end of water inlet pipe 27, is connected to a return pipe 2 that pressure regulator valve 3 is housed on the water inlet pipe 27.The axle head of bent axle is installed belt pulley 26, uses as input power.

Utilize the motor-driven spraying machine of this twin-tub in the field when fruit tree is sprayed insecticide, this machine is placed on the special-purpose dolly or other instruments, is used as power, an end of water inlet pipe racks filter screen 14 is inserted in the soup with engines such as diesel engine or electromotor, on the drug discharging tube joint, connect shower nozzle, get final product work.During work, water intaking valve assembly 12 is under the drive of slide block assembly 7, in pump 13, do reciprocating linear motion, when travelling forward, flat valve 20 is close in the piston cup holder 18, water intaking valve is closed, and the back space of pump 13 enlarges, and pressure reduces, soup is sucked, when slide block assembly 7 moved backward, water intaking valve assembly 12 was opened, i.e. piston cup holder 18 is thrown off with flat valve 20, soup is through the side of cam sleeve 17, by the aperture of water inlet valve block 16, flow into the front portion of pump 13, when slide block assembly 7 moves on, soup with elevated pressures is opened outlet valve assembly 11, be that flat valve 11 moves to left, soup just can enter in the air chamber base 10 in the aperture of spring base 21, and then sprays in shower nozzle.The bent axle of spraying machine rotates a circle, finishes the suction and the discharge process of twice soup.

Air chamber 1 is used for stablizing soup pressure, and soup enters in the air chamber 1, makes air chamber 1 upper air compression and produce certain pressure, and when this machine moved to the dead point, the pressure of this air can make the pressure stability of soup, thereby can make medicinal liquid flow stable.Required pressure during work can be realized by adjusting pressure regulator valve 3.
