Description

[Detailed Description of the Invention] The present invention relates to an engine cooling air intake structure for a harvester, in which a dustproof net is provided in front of a radiator and a suction fan is provided in the rear.

In the above devices, due to the suction power of the suction fan, cooling air was generally strongly sucked and supplied at the center of the front of the radiator, and was supplied in a biased manner to the radiator. There was a problem in that the cooling efficiency of the radiator was reduced due to early concentration of dust particles being sucked and deposited on the part of the dustproof screen corresponding to the center of the front surface of the radiator, leading to early clogging.

In view of the above points, it is an object of the present invention to uniformize the suction and supply of cooling air to a radiator, to suppress the progress of clogging due to adhesion of dust, and to improve cooling efficiency.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

A reaping unit 1 that raises and reaps the planted grain culms in the field, transports the reaped grain culms, changes its posture to a horizontal position and delivers them to the feed chain, and the reaped grains that are transported and supplied by the feed chain. A threshing device 2 for threshing culms and a grain collecting device 3 are connected to a traveling vehicle body equipped with a crawler traveling device 4 and a control section 5 to constitute a combine harvester.

The control section 5 includes a driver's seat 7 provided behind the control box 6, and a radiator 8, a suction fan 9, and an engine E arranged below the driver's seat 7 in the left-right direction of the vehicle body.

A dustproof net 10 is stretched in front of the radiator 8, and there is a gap between the radiator 8 and the dustproof net 10 along the front surface of the radiator 8 and in the opposite direction between the radiator 8 and the radiator 8, In addition, two first partition plates 11, 11 are provided with the front side of the rotation axis X of the suction fan 9 removed and separated by a predetermined interval in the vertical direction, and the first partition plates 11,
11 and the dustproof net 10, there is a gap in the opposing direction, and the ends thereof are overlapped so as to block the interval between the first partition plates 11, 11 when viewed from the front with respect to the radiator 8. A second partition plate 12 is provided, and cooling air is directed from both upper and lower sides of the second partition plate 12 into the gap in the opposing direction between the first partition plates 11, 11, between both 11, 11, and the second partition plate 12. It is configured such that it is distributed and supplied to the radiator 8 through the upper side of one of the partition plates 11 and the lower side of the other.

In addition, in providing the partition plates 11, 11, 12,
Between the radiator 8 and the dustproof screen 10, all of them may be arranged in parallel so that the phases in the opposing directions are different, or four or more partition plates 11, 12 may be arranged in parallel.
... may be provided.

Furthermore, the present invention is configured such that an air intake space is provided above the edge of the radiator 8 with a dustproof net stretched over it, and cooling air is sucked and supplied to the radiator 8 not only from the front but also from above. It can also be applied to

The present invention is applicable not only to combines but also to various harvesting machines such as onion harvesting machines.

In summary, the present invention provides the above-mentioned engine cooling air intake structure for the harvester, in which a partition plate is installed in the space between the radiator 8 and the dustproof net 10 to block the front of the rotation axis X of the suction fan 9. 12 and
A partition plate 11 located behind the partition plate 12
... are arranged side by side along a plane orthogonal to the rotation axis X, and the adjacent end sides of the partition plates 12, 11... are overlapped with each other when viewed from the front with respect to the radiator 8, and , is characterized in that a gap is provided between the opposing directions.

In other words, instead of sucking cooling air directly from the dustproof net 10 in front of the rotation axis X of the suction fan 9, which has a strong suction force, a partition plate 12 is provided in front of the rotation axis X, and this partition plate 12 and partition plates 11 and 11 provided behind this partition plate 12 so that their end sides overlap with each other, the cooling air is sucked in a straight line to the radiator 8. In addition, the suction force can be distributed over the entire front surface of the radiator 8 instead of being concentrated in one part, and the concentrated adhesion of dust to a certain part of the dustproof screen 10 due to cooling air suction can be suppressed, thereby preventing clogging. The cooling air can be supplied to the radiator 8 in a uniform state, and the cooling efficiency of the radiator 8 can be improved.
