Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for removing residues adhering and staying on various parts of a combine, such as a pretreatment unit and a threshing unit, and more particularly to "compressed air" without requiring a complicated mechanical structure. The present invention relates to a residue removal system in a combine that can efficiently remove residues by utilizing the "spraying action of a spray."

[0002]

2. Description of the Related Art In general, a combine is provided with a pre-processing unit which can be lifted and lowered at a position in front of an airframe equipped with a threshing unit and a paddy tank. The pre-processing unit cuts and transports trichomes during traveling of the airframe. After threshing of the transferred harvested culm and threshing in the threshing unit, the paddy remaining in the paddy tank is collected, and shredding and discharging of the straw is performed as a series of operations. .

In the above-described harvesting and threshing operations using a combine, the generation of foreign substances such as fir lilies and straw debris is inevitably caused by the contents of the work, such as when cutting the piloerotic culm or when threshing the reaped cereal culm. When performing the combine operation for a long time, the above-mentioned contaminants accumulate as residues at important points in each part of the machine body. Conventionally, in order to cause inconveniences such as contamination of the paddy into the paddy or a drop in the paddy collection rate, the work of removing the residue deposited on each part of the machine body was performed at regular intervals.

[0004] However, the operation of removing the above-mentioned residue increases the burden on the operator by disassembling and assembling the various parts of the machine, and furthermore, it is necessary to spend time for inspection and maintenance other than the actual operation time of the combine. However, since the overall work efficiency of the combine decreases, a demand has arisen for a combine that can be used efficiently without maintenance.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situation, and has been devised in order to meet a conventional demand. The object of the present invention is to require a complicated mechanical structure. The removal of the desired residue can be easily performed simply by arranging a compact cleaning nozzle without any troublesome work. It is an object of the present invention to provide a residue removal system in a combine which can flexibly cope with only the piping of the piping.

[0006]

Means for Solving the Problems In order to solve the problems, a first technical means employed in the present invention is to perform threshing and sorting of cut culm culms from a vertically movable pre-processing section provided with a cutting and conveying mechanism. Through a threshing unit, in a combine configured to collect threshed paddy, a plurality of cleaning nozzles are respectively arranged at required attachment positions on a body including the pretreatment unit and the threshing unit, And that the residue adhering to and depositing on the surrounding area is removed by the compressed wind of compressed air injected from the cleaning nozzle,

[0007] As a second technical means, a rotary wiper body, which is mounted on the radiator grill surface of the engine disposed on the body, is rotatably supported, and is sprayed from a cleaning nozzle provided in the vicinity thereof. Characterized in that the wiper body is rotationally driven by the compressed air operation of the compressed air to be performed,

As a third technical means, a cleaning nozzle is disposed on the back side of the receiving net in a handling room where the threshing unit is formed. While removing the residue adhering to the receiving net, it is characterized in that the ejection driving of the cleaning nozzle is performed in conjunction with one or both of the raising operation of the pretreatment unit and the rice collecting operation,

Further, as a fourth technical means, a cleaning nozzle is provided in an intermediate region from the end side of the handling drum pivotally supported in the handling room of the threshing section to the starting end side of the straw conveying chain, and the intermediate region is provided. While the straw is successively transferred to the straw transport chain through the straw, the paddy mixed in the straw is removed upward by the compressed air pressure of the compressed air injected from the cleaning nozzle. It is a feature.
