Mini three wheel suction truck for sale
The composition of the suction dung-cart
The suction tank is mainly composed of: tank body, vacuum pump, force-extractor, four-way valve, water and gas separator, oil and gas separator, return tank, direction rotation arm, locking mechanism.
The tank body is the main body of the dunghill. The air hole is connected with the water and gas separator to provide air access to and from the tank. The hole is normally sealed and can be opened for maintenance. The suction and discharge hole is connected with the dung suction rubber pipe and the bottom is connected with the passage of the dung liquid in and out of the tank.
The middle part of the tank body is provided with a platform box, which is usually used for shelving the dung suction hose and standing during maintenance. The tank body is equipped with an anti-sway plate to reduce the damage to the tank body and its frame connection parts caused by the violent sloshing impact of liquid caused by vehicle driving. The front head is provided with an observation tube to facilitate the monitoring of the load and prevent overload. The bottom is provided with a cleaning hole, which is sealed at ordinary times. When cleaning the tank body, the cleaning hole cover can be opened to let the sewage flow out.
The tank body is installed on the frame by means of rigid connection, and a buffer cushion is arranged between the two, which can reduce the damage to the tank body caused by the vibration of the vehicle.
Since the suction rubber pipe is always immersed in the liquid surface, the air in the tank is pumped, because it can not be supplemented and more and more thin, resulting in the pressure in the tank is lower than the atmospheric pressure, that is, under the action of compressed air, the manure is discharged from the tank through the suction rubber pipe.
2. Vacuum pump
The vacuum pump is the key component of the dung suction truck, which is mainly used with the force extractor, three-way and four-position valve to realize the vacuum pumping and pressurizing operation in the tank.
At present, single-stage rotary oil seal vacuum pump is commonly used on the dung suction truck, with ideal working pressure of 200PA--8500PA, featuring convenient installation, high vacuum degree and high efficiency.
The vacuum pump is mainly composed of pump body, rotor and its components, pump shell, rotor blade, slip ring, bearing cover and sealing device. The rotor is wearing parts. In order to facilitate disassembly and repair, the rotary center of the rotor deviates from the center of the pump body.
The working principle is that the eccentric rotor is driven by the force extractor to work, the tank into the compression chamber, when the pressure exceeds the specified value of the exhaust port, the compression chamber automatically open, the compressed air is discharged, so that the air inside the tank is pumped out, repeated circulation, the tank internal vacuum is formed.
In order to ensure the normal operation of the vacuum pump and avoid pollution, the oil and gas separator and water and gas separator were installed to filter the water vapor and oil and gas in the compressed gas when producing the dung suction truck.
3. Force extractor
The operation of the manure suction truck is driven by the engine power through the power extractor and the transmission shaft. The power extractor is installed on the left or right side of the transmission, and the upper part of the operation handle is located in the middle plate of the cab.
The force extractor consists of input gear, input shaft, intermediate gear, intermediate shaft, output shaft, output gear, fork pulling shaft, fork pulling shaft and operating handle.
The input gear and the output gear of the transmission are normally engaged pairs. Before starting the vacuum pump, the transmission output gear is normally engaged pair. Vacuum pump before starting, hang up the transmission into the gap, and then start the engine, clutch, open the power switch, the reach the fork shaft, fork to drive the output gear on the output shaft, slide and intermediate gear meshing, the output shaft by spline gear and output to the input gear, intermediate gear is passed to the output gear, in the output coupling transmission to the drive shaft. Thus driving the vacuum pump rotation.
4. Four-way valve
Vacuum pump can only counterclockwise rotation (facing the front), to calmly tank air intake, or to the tank out of air, you need to use the four-way valve.
The four-way valve is connected with the tank, the vacuum pump and the return tank atmosphere respectively. The four-way valve is provided with a partition. Change the suction direction of the vacuum pump. When the four-way valve connects the tank to the vacuum pump, the manure truck will discharge the tank.
5. Water and gas separator
The water and gas separator is located on the top of the front of the tank and the back of the tank. The inner part of the utility model is provided with a gas pipe whose two sides are provided with rectangular holes for air to enter and exit the tank. In the pumping operation, the air in the tank comes out from the rectangular hole, the volume expands suddenly, the flow rate decreases, and the number of heavy water molecules decreases, which can reduce the harm to the lubricating oil and the parts.
6. Oil and gas separator
The compressed air discharged from the vacuum pump has a high speed and carries a large number of oil droplets when it breaks through the oil film. Oil and gas separation is located in the right middle of the dung truck frame, with vacuum pump in front and back to the oil tank. Oil and gas separation is equipped with baffle tubing. When compressed air to enter, it suddenly expanded volume, velocity, change flow direction, through the porous pipe outflow, because velocity is reduced, oil and gas molecules on the wall, the wall of hole collision aggravate, heavy large part oil molecules and is attached to the wall, condensing buckle form oil droplets, suitable to the wall and spilled oil from flowing back to the fuel tank, after initial purification of compressed air to flow back to the tank top.
7. Return to the oil tank
The return tank is located in the right middle of the frame, with oil and gas separator on the left and four-way valve on the right.
Back to the tank with oil baffle network, gateway, not the compressed air in from the oil and gas separator, then must pass through multiple obstacles, to row to the four-way valve, due to the volume suddenly doubled back to the fuel tank, air flow rate is decreased obviously, and obstacles, such as oil baffle net, compressed air must be here by multiple obstacles, to row to the four-way valve, due to the volume suddenly doubled back to the fuel tank, air flow rate is decreased obviously, and obstacles, such as oil baffle net, oil from compressed air molecules increase touch shan, adhesive lining and mesh surface, and then into the bottom of the compressed air purification by over again flow to the four-way valve.
The lower part of the return tank is provided with a straight cock, which can control the lubricating oil blade supplied to the vacuum pump.
8. Directional rotation arm
The directional rotary arm is located at the top of the rear of the container. It is composed of the boom seat, connecting pipe counterweight block, support frame and other parts. The front is connected with the dung suction rubber pipe, and the rear is connected with the siphon boom seat, which can be operated. As a result of setting counterweight piece, bear the labor intensity when fecal suction pipe, the connection pipe of two ends of support pipe is 90, its curved outer diameter is set with clear pottery hole, sealing at ordinary times, when fecal suction hose or straw is blocked, can open clear pottery hole cover, clear plugging.
9. Locking mechanism
The locking mechanism is mainly composed of a fixing device, whose function is to ensure the sealing of the cleaning hole cover. The fixing device is located at the lower part of the right middle part of the frame, which is mainly composed of operating rod, locking pin and positioning plate. When the operating rod moves backward, the pull rod moves forward, and the rotating shaft drives the plate arm to swing counterclockwise, so that the cleaning hole cover is tightly blocked by the cleaning hole to achieve the purpose of sealing. The operating rod is provided with a locking pin, a spring, a pulling rod and a pinching handle. When the joystick moves backward and the locking lock slides along the outer ring of the positioning plate into the positioning slot, it is pushed into the position slot by the spring at the rear end. Because the five sides of the locking pin are restrained, it cannot be ejected. The positioning slot can ensure that the bar will not be jolted due to the vibration in running, and then the locking function is realized.
