Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a reaping harvester in which a control section is installed on one side of the rear side of the reaping pretreatment section.
The present invention relates to a technology for improving the working environment of a reaping harvester by effectively preventing dust from entering the control section as the machine advances.

[Conventional technology]

In a reaping/harvesting machine where the control section is installed on the rear side of the pre-harvesting section, the reaping device is placed in front of the control section, so a large amount of dust is generated during the reaping operation as the machine moves forward. There is a strong tendency for the broken dust to reach the operator, causing a problem that hinders confirmation of the front and work status. Therefore,
As shown in Utility Model Application Publication No. 56-42419,
The first idea that came to mind was to provide a cabin that covered the entire control section.

However, installing a cabin requires a major modification of the control section, which increases the cost and reduces the living space of the control section, making it difficult to adopt. ,
As shown in Utility Model Application Publication No. 59-633,
A means of installing a sunshade that is relatively bulky enough to cover the head of a seated pilot, or
As shown in Publication No. 57-56438, a low-bulk sunshade with good visibility is provided, and a means is adopted to generate wind that blows downward from the sunshade to form an air curtain for the control section. In particular, it was considered that the dust caused by the movement of the aircraft would be less likely to reach the pilot's face.

[The problem that the idea attempts to solve]

However, in the former conventional technology, dust still tends to reach from the open space below the sunshade, and in the latter conventional technology, although an air curtain is formed in front of the control section, Since the direction and the direction of dust intrusion were opposite to each other, the movement of the aircraft encouraged the intrusion of dust, and even with this measure, the dustproofness of the front side of the control section was not sufficient.

In view of the above-mentioned circumstances, it is an object of the present invention to construct a means for better preventing dust from reaching the operator from the pre-reaping treatment section at a relatively low cost.

[Means to solve the problem]

For the above purpose, the present invention constructs an awning above the control section, horizontally mounts a cross-flow fan on the front edge of the awning, and installs a cross-flow fan in front of the meter panel located in front of the control section. A windshield that rises upward is installed, and a slit-shaped outlet in the crossflow fan that opens downward is set and arranged so that the wind generated by the crossflow fan blows down along the front of the windshield. This is a characteristic configuration.

[Effect]

In other words, by installing a windshield in front of the control section, dust coming from the front is blocked by a physical wall, so compared to conventional methods where there is almost no wall or an airflow wall using an air curtain.
A remarkable effect of preventing the intrusion of dust can be expected.

By the way, with the above method, it is conceivable that dust may adhere to the front surface of the windshield, deteriorating the forward visibility.
The wide wind blowing downward from the cross-flow fan installed in the sunshade forms an air curtain that prevents dust from entering, and also prevents dust from adhering to the front of the windshield due to the blowing wind. As a result, good visibility is maintained, and not only the windshield but also the air curtain function to prevent dust from entering.

Further, since the configuration for this purpose mainly includes a cross-flow fan and a windshield, it can be realized at a relatively low cost.

[Effect of idea]

As a result, the interaction between the windshield and air curtain can effectively prevent dust from reaching the operator from the front, without deteriorating visibility or significantly increasing costs. We could provide a harvester.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 2 and 7, there is a handling room A in the front, a grain tank 1 in the upper center, a threshing section B extending from the center to the rear, and a control section on the side of the handling room A. A car body formed with C is configured to be self-propelled by a crawler traveling device 2, and a reaping pre-processing section D consisting of a reel 3, a reaping device 4, an auger 5, and a feeder 6 is connected to the front end of the car body to create a DC type. Combine is configured.

A handling barrel 7 is horizontally installed in the handling room A, and the threshing section B includes a straw walker 8 that sends waste straw to the rear, a chaff sieve 9, a clean sieve, and a straw walker 8 that sends the waste straw to the rear. A rack plate 11 for sending the grains to the oscillating sorting section consisting of 10, etc., a first screw 12 for collecting the first grains from the oscillating sorting section, a second screw 13 for collecting the second grains from the oscillating sorting section, and It consists of 14 Chinese roofs that supply wind.

As shown in FIGS. 1 to 5, the control section C
is provided with a seat 15, a control handle bar 16, a meter panel 17, etc., and a cloth sunshade 19 is constructed from the upper ends of pillars 18, 18 erected on the right and left behind the seat 15 toward the front. Then, cross-flow fans 20, 20 are disposed horizontally on the front edge of this awning 19 and the side edge on the side of the pre-reaping treatment section D, and the slit-shaped air outlets 20a, 20a of each fan 20 are directed downward, respectively. It opens to form an air curtain at the front and sides of the control section.

The front side of the fans 20, 20 is the sunshade 1.
It has a length spanning the entire width of 9, and the side ones are
By arranging it close to the fan 20, no gap is created at the corners of the air curtain. Further, motors M, M are attached to the respective fans 20, 20, and as shown in FIG.
Electrical circuit E in which current can be adjusted using a power supply 21, a main switch 22, and a Darlington transistor 23
The respective motors M and M are provided in parallel, and further,
A control device 24 that drives the transistor 23 and a sensor 25 that detects the traveling speed of the combine are linked, so that when the traveling speed increases, the fan 20,
The air blown out from 20 is increased.

A wind direction plate 26 for adjusting the wind direction is swingably provided at the air outlet 20a.

In addition, a windshield 27 made of transparent resin and having a relatively small vertical dimension is attached to the outer wall surface of the meter panel 17 to help prevent dust from entering the control section C, and at the same time, the wind from the air curtain blows away the windshield. 2
It is designed to remove dust adhering to 7.
