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 which can prevent dust generated above a mowing portion and in front of a threshing portion from reaching an operator of a driving operation portion.

[0002]

2. Description of the Related Art Conventionally, as can be seen in Japanese Patent Application No. 2-80413 filed by the present applicant, a mowing section provided at the front of the body so as to be able to move up and down is provided with a driving operation section side and side sections. In a combine which is equipped with an air blower having an upwardly directed blow port in communication with a blower, air can be blown upward from the blow port to form an air curtain. At times, the structure was such that water droplets could easily hit the blower fan or get into the blower.

[0003]

However, since the air curtain is blown upward and flows upward, dust generated on the reaping portion side is sucked into the airflow and soars upward, and a part of the air curtain rises. There have been such drawbacks that the operator gets down, the dust is sucked into the blower, so that the dust is soared by the air curtain, and water drops are applied when washing the car, causing troubles in the blower fan and the motor.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem and to provide good dust protection. Therefore, the upper side of the blower drum, which is located at a lower position than the blowing port, has: with the upper portion of the ear portion guide plate which is obliquely upwardly of the upper carrier adhered by interposing a horizontal top plate, the top plate
Is provided with a blower inside .

[0005]

Therefore, the air blower is in a state where dust is not sucked, and the air flowing out of the blowing port is guided by the dust-proof cover and is directed sideways to the upper side of the reaping portion, while flowing to the outside of the body opposite to the operator. Dust generated above the mowing unit and in front of the threshing unit can be flown to the outside of the machine, and when washing the car, it is difficult for water droplets to hit the blowing port, and also to prevent it from hitting the blower You will be able to wash your car.

[0006]

FIG. 2 shows a side view of the combine, in which a raising case 8, a cutting blade 9, an upper carrier 3 and the like are provided in front of a threshing section C mounted above both crawlers 7 to ascend and descend. A free mowing portion A is provided, and on the right side of the mowing portion A,
A driving operation unit B equipped with a steering column 11, a step 12, a seat 13 and the like is provided, and a paddy tank 14 and the like are disposed behind the driving operation unit B to have the same configuration as the conventional structure.

[0007] An air blower 2 having an upward blowing port 2a is provided on the side of the operation section B of the mowing section A in the same manner as in the conventional type, but the height is lower than that of the angling port 2a by H. the upper side surface of the air cylinder 2 is to adhere the upper portion of the ear portion guide plate 4 which is obliquely upwardly of the upper carrier 3 such that no gap by interposing a top plate 5 of the horizontal, the top plate 5 below
Has a fan 15 driven by a motor 10 and has a blower 1 having an intake hole 16 on the front side, and a blower opening 17 of the blower 1 communicates with a side surface of the blower drum 2. The upper surface 6a of the dustproof cover 6 extending upward from the side of the blowing port 2a is configured to extend in a horizontal direction from above the blowing port 2a to a position above the cutting portion A so as to be partially longer.

Therefore, the dust generated from the cutting section A and the threshing section B is not sucked by the blower 1, and the air flowing out from the blowing port 2a is guided by the dustproof cover 6 and is directed laterally upward to the cutting section A. As a result, dust generated above the mowing unit A and in front of the threshing unit C can flow to the outside of the machine body while flowing to the outside of the machine body on the side opposite to the driving operation unit B. In addition, water droplets are hardly applied to the blowing port 2a, and the blower 1 and the motor 10
It will be possible to wash the car without getting in the way.

FIG. 6 shows another example, in which a blower drum 2 communicating with a blower 1 is formed into a small body, and connection tubes 18 are provided at both ends thereof.
19, the blower cylinder 2b as another extension unit can be attached to the reaping section A via the support guide 20,
The connection cylinder 21 on one side of the blower cylinder 2b can be connected to the connection cylinder 19 directly or via an elbow 22, and the connection cylinder 23 on the other side can be fitted with a cap 24 or can be connected to another blower cylinder. The air blower 2 is used as a base unit, and other air blowers 2
b can be attached as an extension unit to a necessary part.

[0010]

As described above, according to the present invention, it is possible to prevent dust from being absorbed by the blower 1 and
The air flowing out from a is guided by the dustproof cover 6 to the outside of the machine opposite to the operator, and the dust generated above the cutting unit A and in front of the threshing unit is caused to flow to the outside of the machine by the dust. It can be reliably prevented from spreading, and when washing the car, the car can be washed well by preventing water droplets from hitting the blowing port 2a and the blower 1, and has a feature that it can be implemented easily with a simple structure. .
