Abstract

PURPOSE:To prevent the clogging of a dust-proofing mesh by using a blower for sending dust-proofing air flow to a nozzle and placing the blower above a grain tank and near a grain-discharging auger, thereby housing the blower in a compactly arranged state in a gap above the grain tank. CONSTITUTION:A dust-proofing mesh 9 is extended on a suction port 8 of an engine 7 placed at a side of a grain tank 5. An air-blowing nozzle 10 is formed outside of the dust-proofing mesh and opened along a side of the mesh. A blower 11 for sending dust-proofing air flow to the nozzle is placed in a gap between the grain tank and a grain-discharging auger 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine dustproof device and is used not only in combine harvesters but also in harvesters and the like.

[0002]

2. Description of the Related Art In the conventional structure, as a device for removing dust adhering to a dustproof net, there is a device for moving a cleaning brush along the surface of the dustproof net.

[0003]

In the working environment of this type of agricultural machine, since the target of the work is soil or a grain stalk (straw), dust is easily generated and it is difficult to take measures against it. In particular, for engines that require clean air to be sucked, a dust screen is stretched over the air intake to protect it from dust, but dust adheres to the mesh surface of this dust screen. Then, a trouble that causes clogging occurs.

If the dust-proof net becomes clogged, the engine will be damaged due to a reduction in horsepower, overheat, etc. Therefore, the worker must interrupt the work and clean the dust-proof net. I have to. Therefore, there is a problem that the work cannot be performed continuously and must be interrupted frequently for cleaning.

Further, the blower that blows the blast must be installed outside the swirl range that does not interfere with the discharge auger that swirls upward when the grains are discharged from the grain tank to the outside.

[0006]

The present invention takes the following technical means in order to solve the above-mentioned problems. That is, the thresher 3 is mounted on the chassis 2 having the traveling device 1.
And a grain tank 5 having a grain discharging auger-4, an engine 7 for transmitting each rotating portion of the machine body 6 is provided on one side of the grain tank 5, and a dust-proof is provided at an intake port 8 of the engine 7. A net 9 is provided in a stretched manner, a blowout port 10 is formed outside the dustproof net 9 along one side thereof, and a blower 11 for blowing dustproof wind to the blowout port 10 is provided on the upper surface of the Glen tank 5. It is a combine dustproof device installed at a position close to the grain discharge ogre-4.

[0007]

EXAMPLE First, the structure will be described. Chassis 2
Has a traveling device 1 composed of a crawler, a threshing machine 3 and a Glen tank 5 are provided side by side, and a cabin 12 is mounted on the front side of the Glen tank 5. The grain discharging auger-4 provided on the rear side of the grain tank 5 is configured to swivel by a conventionally known swivel device to transport the grain to the outside.

Then, the pre-processing section 13 includes a mowing device 14,
A weeding rod 15, a take-in reel 16 and the like are integrally provided and provided at the front part of the chassis 2. The engine 7 is located on the rear side of the grain tank 5, that is, on the grain discharge auger side, and is mounted on the chassis 2. The engine 7 is configured to be capable of transmitting and rotating the rotating parts of the machine body 6 described above. The engine 7 has an air cleaner attached to it, and has a cooling fan 17,
A radiator 18 is arranged behind.

The engine 7 is constructed by surrounding it with a box-shaped engine room 20 having an engine cover 19 on its side surface. The intake chamber 21 is provided so as to be connected to the upper portion of the engine room 20 described above, and the intake port 8 is opened on the same outer side surface as the engine cover 19 so as to prevent dust.
Is installed.

The intake chamber 21 communicates with the engine room 20, sucks outside air from the dustproof net 9 through the intake port 8, supplies clean air to the air cleaner, and cools it. It has a structure that can be used as wind. Blower 1
Reference numeral 1 denotes a rotary impeller, which is provided on the upper surface of the grain tank 5 so as to be close to the base of the grain discharging auger -4 and provided so that it can be driven through a transmission mechanism 22.
It is configured to communicate with the space 24.

The jet port 10 is opened above the dust-proof net 9 in the upper part of the intake chamber 21 so as to allow a jet, and one end of the hose 2 is provided.
It connects to 4. Next, the operation will be described.
First, when the engine 7 is started to drive the rotating parts of the machine body, the chassis 2 is propelled by the traveling device 1 and starts working while moving forward.

Then, the grain culms in the field are scraped by the scraping reel 16 at the front part, cut by the cutting device 14 and supplied to the threshing machine 3 to be subjected to threshing action. Then, the threshed grains are stored in the Glen tank 5. Now, during such a continuous operation, the engine 7 continues to suck the clean air from which dust has been removed as cooling air through the dustproof net 9 by the rotating cooling fan 17.

At this time, the air around the chassis 2 is scattered and contaminated with dust, straw dust, and dust generated from the grain culms (straw) that have been cut and threshed. There is. Therefore, since the dustproof net 9 allows the air sucked into the intake chamber 21 to pass through while being filtered, and clean air is being sent, dust tends to adhere to the entire surface of the net.
At that time, the blower 11 sucks air by the rotary impeller that is driven on the upper surface of the Glen tank 5 and sends the air from the blower port 23 to the hose 24 so that the blower port 10 strongly blows the air downward.

Then, the blast blows through the front surface of the dustproof net 9. At that time, as described above, the dust that is about to adhere to the dustproof net 9 can be blown off immediately before the attachment. As described above, the air blasted by the blower 11 is supplied to the intake chamber 21 and the engine room 2.
It is possible to prevent dust from adhering to the dustproof net 9 and the engine cover 19 in the process of blowing through the outside of 0.

Next, in the work of transporting the grain in the grain tank 5 to the outside of the machine, after raising the grain discharge ogre-4, the grain is freely swung to a target position (transport vehicle such as a truck). Set to and carry out. At this time, the grain discharging auger-4 does not collide with an obstacle at the time of turning, so that the minimum height is set to the cabin 12
Since it has a roof, it is possible to work safely without colliding with the blower 11.

[0016]

As described above, according to the present invention, the thresher and the grain tank having the grain discharging auger are provided on the chassis having the traveling device, and the rotation of the machine body is provided on one side of the grain tank. An engine for transmitting each part is provided, and a dust-proof net is stretched at the intake port of the engine. A blowout port is formed outside the dust-proof screen along one side thereof, and dust-proof wind is blown to the blowout port. A blower for discharging the grain on the upper surface of the Glen tank.
Since it is installed at a position close to the girder, it prevents the clogging of the dust-proof net before it is done, but it is set to a position where it does not interfere with the grain discharge auger that turns the blower, and work safely There is a feature that can be.
