Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

The invention relates to a pneumatic grain elevator, which utilizes the pneumatic transmission principle to move grains from one side to a desired position, can operate in places where large-scale equipment grain raking machines, packing augers and forklifts cannot work in special environments, and is ideal equipment for locally heating, topping and leveling stored grains.

Referring to fig. 1 and 2, the pneumatic grain elevator of the present invention includes a base frame 1. The underframe 1 is used for providing support for other parts of the grain elevator.

Preferably, wheels 14 are mounted below the chassis 1. More preferably, four wheels 14 are mounted below the base frame 1. Still preferably, a traction frame 15 is installed in front of the base frame 1. In this way, it can be connected to a traction device, such as a traction vehicle, by means of said traction frame 15 and moved by said vehicle 14 to the location where it is desired to suck grain, under the traction of said traction vehicle. Therefore, the movable type electric bicycle is very convenient to move and use.

The base frame 1 is provided with a material separation sand-shaped dragon 2 and a dust falling sand-shaped dragon 6. A grain suction hose which is not shown in the figure is arranged on the suction nozzle 3 of the material separation shakelong 2. The grain suction hose can extend to the position where grain suction is needed.

The top of the material separation sand-falling device 2 is connected with the inlet of the dust-falling sand-falling device 6 through a first conduit 5, and the lower part of the material separation sand-falling device is connected with the inlet of the air seal machine 18.

The air seal machinery 18 is driven by the air seal machinery 13 arranged on the chassis 1 and the outlet of the air seal machinery 18 is connected with the discharge port 4. A discharge hose not shown in the figure is mounted on the discharge port 4. The discharge hose can be extended to a location where the grain needs to be moved.

The top of dust fall husky ke long 6 links to each other with roots's fan 8 through second pipe 7, and the lower part passes through flange 11 and links to each other with dust removal case 9. The Roots blower 8 is driven by a Roots blower motor 10 mounted on the base frame 1, and a silencer 17 is mounted on the Roots blower 8.

And a distribution box 12 for supplying power to the air seal machinery motor 13 and the Roots blower 10 is also arranged on the underframe 1.

Preferably, the grain suction hose and the discharge hose are nylon elastic hoses used in four seasons. More preferably, the lengths of the grain suction hose and the discharge hose are both 60 meters.

Further, it is preferable that an output shaft of the roots blower motor 10 is connected to a drive shaft of the roots blower 8 through a triangular belt. More preferably, a v-belt protective cover 16 is provided on the outside of the v-belt.

When the grain elevator is used, the grain-sucking hose with the proper length is selected according to the position of the grain-sucking point away from the grain elevator, and the discharging hose with the proper length is selected according to the position of the grain-receiving point away from the grain elevator. Then, one end of the grain suction hose is placed at a grain suction point, and the other end of the grain suction hose is connected with the suction nozzle 3 of the material separation shakelong 2. Meanwhile, one end of the discharging hose is placed to a grain receiving point, and the other end of the discharging hose is connected with the discharging port 4.

The air seal machinery motor 13 and the Roots blower motor 10 are then powered through the electric box 12. The Roots blower motor 10 drives the Roots blower 8 to work, and negative pressure is generated through the Roots blower 8. And the grains and the air at the grain suction point enter the material separation salon 2 through the grain suction hose and the suction nozzle 3 under the action of the negative pressure.

The sucked grain and air are separated from each other through the material separation shakelong 2. Wherein the grain (containing part of the dust) spirally turns along the material separating shacklen 2 and falls down into the air seal 18.

The air seal machinery 13 drives the air seal 18 to work. In this way, the grain (containing a part of dust) falling into the air seal 18 is conveyed to the discharge port 4 through the air seal 18 and conveyed to a required place, that is, the grain receiving point, by the positive pressure air flow through the discharge hose.

Meanwhile, the air separated from the grains moves upwards along the material separation salon 2 and enters the dust fall salon 6 through the first conduit 5. The dust and the like in the air spirally rotate along the dustfall sand-lock 6 to fall into the dust removing box 9, and the air separated from the dust moves upwards along the withdrawn sand-lock 6, enters the roots blower 8 through the second guide rail 7 and is discharged by the roots blower 8.

The grain elevator of the invention adopts the principle of the shakelong, so that gas and grains are separated instantly and descend spirally, the collision of the grains with the tank body is greatly reduced, and the breakage rate is reduced to be in a range meeting the national standard. Meanwhile, the environment-friendly dust collection box adopts the two-time pressure reduction treatment of the sand-dragon for the environmental protection and dust treatment, and the dust enters the dust removal box, so that the dust is collected more tightly. Moreover, the grain suction hose and the discharge hose are convenient and quick to assemble, and the angle of the operation point can be adjusted freely as required. And the discharging hose can be directly connected and conveyed, and the grain outlet can be adjusted to unload grains in situ and unload the grains to a conveyor for direct loading. Finally, the device can work normally in severe weather such as rain and snow, is not limited by various natural conditions, is additionally provided with a secondary silencing system, and has low noise.

The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive.
