Description

[Detailed Description of the Invention] The present invention relates to a dust suction device in a combine harvester.

In other words, the present invention provides a system that allows the work to be carried out sanitarily by sucking up dust generated during combine harvester work using a single intake/exhaust fan body. Conventionally, there is a device described in Japanese Utility Model Publication No. 38-6666 that allows cleaning to be performed using the exhaust air of a dust extractor. However, since this dust extractor sucks the inside of the threshing machine, it has the disadvantage that it cannot suck dust from the area where the worker is working.

The present invention has been devised to provide a comfortable working environment for workers.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a plan view of the combine harvester, in which a reaping section C equipped with each lifting case 6, each conveying device 7, etc. is installed at the front part of the machine body, and a threshing section is installed at the rear side of the reaping section C. A control column 9 and a seat 10 are installed in front and rear of the step 8 installed at the rear side of the reaping part C, and behind the seat 10 there are both paddy outlets 11, 11 at the bottom. Erect a paddy tank 12,
An engine section 13 is installed at the rear of the paddy tank 12 and has the same structure as the conventional structure.

A handling chamber 1 containing a handling cylinder 14 in the threshing section
5 and the outside of the supply date 16 becomes a dust generation part A, and a dust suction duct 4a is connected and connected above the guide cover 17 that opens above it.
Paddy tank 1 located above the paddy outlets 11, 11
The lower side of 2 becomes the dust generating part B, and a dust suction duct 4b is connected to one end of the guide cover 18 covering that part, and in the same way, for example, the side of the sheet 10 or other places. The dust generating part is equipped with a dust suction duct so as to be visible.

Reference numeral A denotes an intake/exhaust fan body, which is fixed to the rear part of the fuselage on the outside of the engine section 13, and has an intake port 3 on one side of its outer periphery and an exhaust port 1 on the other side. A cross-flow fan a is axially mounted inside the fan a and installed so as to be rotatably driven from the engine part 13 side, and the duct 4 extending from the intake port 3 is connected to the ducts 4a and 4b, respectively. Configure.

Further, an opening control valve 2 having an opening 2a formed therein is slidably inserted into the exhaust port 1 of the intake/exhaust fan body A to adjust the cross-sectional area on the exhaust side. A discharge port 1a near the rear of the aircraft body is provided, and a base portion 5a of a long blow tube 5 made of a flexible hose is removably fitted into the discharge port 1a. 5b is installed so as to be able to look toward the conveyor gutter of the threshing section B and each section where residual rice remains.

Therefore, when working on a combine harvester, as shown in Fig. 2, if the blower tube 5 is removed and the outlet port 1a of the intake/exhaust fan body A is opened to the rear of the machine and the opening control valve 2 is opened, the cross-flow fan a By rotating as shown by arrow C, the dust generated in the dust generating parts A and B is sucked into the intake/exhaust fan body A, and is collectively discharged rearward from the discharge port 1a. It is discharged all at the rear from the discharge port 1a, allowing the operator on the machine to perform sanitary work.

In addition, after the combine harvesting operation, as shown in FIG. By directing the air to each part such as part B, the air can be used for cleaning.

Note that by adjusting the cross-sectional area on the exhaust port 1 side using the opening control valve 2, the wind force can be adjusted according to a desired state.

The present invention has the following effects.

A single intake/exhaust fan can effectively suck up dust at the entrance of the handling room and the rice receiving area, where a large amount of dust is generated. In addition, the intake and exhaust fans are installed at the rear of the machine, and the exhaust ports are also installed towards the rear of the machine, so there is plenty of installation space and the dust does not fall on the workers, allowing for sanitary work.
