Description

[Detailed explanation of the idea] TECHNICAL FIELD The present invention relates to a dust removal device for a flipping grain lifting machine.

Conventionally, the vaulting grain lifting machine used for agricultural work, etc., generates a considerable amount of wind due to its structure, and the dust attached to and mixed in the grains is blown up from the grain outlet of the jumping grain raising machine. The grain storage areas were filled with dust that was blown up and became very unhygienic.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dust evacuation device that sucks out dust mixed in grains while they are being transferred by a flipping grain lifting machine.

To remove dust during transfer using a flip-up grain lifting machine, a grain lifting cylinder is formed downward through a curved part at the top, and a flowing grain cylinder with a gentler slope than the downward slope is connected to the floating grain cylinder. A dust suction chamber is provided next to the upper part, a dust collection port is provided on the partition wall at the boundary of the dust suction chamber, and a dust suction port that communicates with the exhaust fan is provided at the top of the dust suction chamber, so that the grains from the hoisting machine are transported to the bottom surface of the grain cylinder. The dust is thrown up into the air, and the dust is discharged to a predetermined location by an exhaust fan through a dust collection port, a dust suction chamber, and a dust suction port.

An embodiment of the present invention will be described based on the drawings.

FIG. 1 is a front partial vertical sectional view of a flipping grain lifting machine equipped with the device of the present invention, and FIG. 2 is a plan view thereof. Reference numeral 1 denotes a hoisting device consisting of a hoisting case 2 and grain lifting blades 3, and a grain supply port 7 is provided on the side. A grain lifting cylinder 4 is provided upward from the lifting device 1, and the grain lifting cylinder 4 becomes a guide cylinder 13 with a downward slope after passing through a curved portion 5 at the top. An outlet 6 is provided through the tube 14. A dust exhaust port 15 is provided at the top of the grain barrel 14.
A dust suction chamber 8 is provided through the dust suction chamber 8, a dust suction port 9 is provided in the upper part of the dust suction chamber 8, and an exhaust fan 11 is provided through a suction pipe 10 made of a flexible member or the like. 12 is an exhaust port of the exhaust fan 11.

As configured as above, when grains are fed from the supply port 7, the grains are jumped up into the grain lifting cylinder 4 by the grain lifting blades 3, are transferred downward by the curved part 5 and the guide cylinder 13, and are The loose grain is sprayed onto the lower surface of the barrel 14. The grains and dust blown onto the lower surface of the flow grain tube 14 jump up, and the dust with a light specific gravity is removed from the dust suction chamber 8, which is under negative pressure by the exhaust fan 11.
The air blows up, is sucked in, and is discharged to a predetermined location through the air exhaust port 12. The grains having a heavy specific gravity flow directly through the grain cylinder 14 and are accumulated at a predetermined location through the outlet 6.

As described above, the present invention rapidly changes the direction of the thrown up grains, kicks up the dust mixed in the grains, and sucks and removes the dust, so that dust can be efficiently removed from the grains. In addition, since the wind generated by the flip-up grain lifting machine is also sucked, the wind blowing from the grain outlet can be suppressed as much as possible, and the flying up of dust in the grain storage area can be reduced. Therefore, very hygienic grain frying work can be performed.
