JPH0928158A - Apparatus for raising up grain culm of combine harvester - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for raising up grain culms of a combine harvester, capable of facilitating maintenance operations and excellent in operating efficiency such as removal of clogged waste straws by providing a case gap for freely inserting an operator's hand between mutually adjacent and opposite inner side edges. SOLUTION: This apparatus for raising up grain culms of a combine harvester is obtained by installing raising up cases 3 and 4 for protruding raising up lugs 2 along the outer side edges 1, raising up and guiding culm bodies in a parallel state and providing each case gap 6 for freely inserting an operator's hand between the mutually adjacent and opposite inner side edges 5. Furthermore, each guide rod 27 extending from a grass dividing unit 12 to the rear upper part is installed between the protruding and opposite parts of the raising up lugs 2 between the raising up cases 3 and 4 to guide the grain culms raised up with the raising up lugs 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine culm raising device for combine harvesters, and can be used for combine harvesters having multiple cuttings.

[0002]

2. Description of the Related Art In a combine of multiple cutting type, a combine harvester having a wide cutting range has a wide cutting width, and since the grain culm raising cases are lined up in multiple rows in front of the reaping device, the cultivated grain culm is mowed. When troubles such as clogging occur in the central part of the device, it is difficult to insert a hand between the raising lugs of each grain culm raising device, and it is difficult to perform maintenance.

[0003]

According to the present invention, raising cases 3 and 4 are provided in parallel with each other so that the raising lug 2 is projected along the outer edge 1 to guide and guide the culm, and the raising cases 3 and 4 are adjacent to each other and face each other. A space 6 between the inner edges 5 to allow insertion of the operator's hand.
The grain culm raising device of the combine is provided.

[0004]

During the cutting operation, the cutting lugs 2 of the grain culm raising cases 3 and 4 are raised so that the culms have a fixed posture and are collected and fed. Clogs, entanglements, and the like of the cut grain culms are likely to occur in the cutting and collecting section on the rear side of the grain culm raising cases 3, 4 and the like. When such a grain culm is jammed or entangled in the harvesting and feeding section, the harvesting transmission is temporarily stopped and the raising case 3,
Insert the hand to the rear side from the case interval 6 between 4 and remove the clogged straw waste.

Since the pull-up lug 2 does not project in the case interval 6 portions, the hands can be freely moved up and down along the inner edge 5 of the pull-up cases 3 and 4, and maintenance work is easy.

[0006]

EXAMPLE A combine is a threshing device 7 of a self-throwing type on a chassis 23 having a traveling device composed of crawlers, a reaping device 8 for supplying a cultivated culm to the threshing device 7, a control device 9, a threshing device. The grain tank 10 for accommodating the grains threshed in 7 and the cutter 11 for cutting and discharging the threshed culms are arranged to cut and thresh rice and wheat.

The harvesting device 8 includes a harvesting frame 24.
Is supported 26 by a hydraulic lift cylinder 25 so that it can be raised and lowered with respect to the chassis 23, and the grass body 12,
Raising cases 3 and 4 having raising lugs 2 for raising the cultivated grain culms in a fixed posture, a rugged rug belt 13 and a rake star wheel 14 for scraping the culled grain culms, and the raked grains. A cutting blade device 15 for cutting the base of the culm, a collecting chain 16 for collecting the cut grain culm to the rear side, and a guide rod 1.
7. A stock source chain 19 and a cutting rod 20 for holding and transporting the collected grain culm to the feed chain 18 of the threshing device 7, a tip transport lug chain 21, and the like are provided.

The grain culm raising cases 3 and 4 are provided obliquely on the front upper part of the scraping lug belt 13 for collecting and the like, and the raising lugs 2 are protruded into the raising passages from both left and right sides to be rearward from the front lower end. While moving upward, the grain culms are engaged and lifted to raise the culms, and the postures are arranged in a certain standing posture. Chains are suspended in the raising cases 3 and 4, and raising lugs 2 are erected up and down at regular intervals in each chain. In the raising case 3, the raising cases on the left side in a front view are horizontally moved sideways. It protrudes and is in a state of being retracted into the raising case 3 in the descending stroke on the right side. Further, the raising case 4 on the other side projects and raises in the ascending stroke on the right side, and retracts in the descending stroke on the left side. A guide rod 27 extending from the grass body 12 to the upper rear portion is provided between the protruding facing portions of the raising lugs 2 between the raising cases 3 and 4, and guides the grain culms raised by the raising lugs 2.

In the example shown in the figure, the outer edge 1 side of the grain culm raising cases 3 and 4 is opposed every two rows in a six-row cutting form. The raising cases 3 and 4 for raising the two lines in the central portion are arranged such that the raising cases 4 and 3 arranged on the outside and the inner edge 5 face each other,
The case interval 6 is formed as wide as possible so that the operator can insert his / her hand deeply from the front side to the rear side. In the front of the lower end of the space 6 between these cases,
Is provided.

The grain culm raised by the grain culm raising device as described above is cut by the cutting blade device 15 while being scraped by the scraping lug belt 13, the star wheel 14 and the like. This cut grain culm is guided and transferred to the collecting chain 16 or the guide rod and is collected to the rear side. This pick-up culm is based on the stock department, stock company 1
It is held between 9 and the slinging rod 20, and the tip portion is engaged with the tip transporting lug chain 21 to be transported and fed to the feeding posture of the threshing device 7.

The stock chain 19 is slidably guided by a chain guide 28 having an L-shaped cross section between front and rear sprockets and rolling wheels. The front and rear ends of the chain guide 28 are attached to the transport frame 29 with bolts 30. A chain support guide 31 is attached to the lower side of the chain guide 28, that is, the stocker side with the bolt 30 with a collar 32 interposed. The chain support guide 31 bends the tip edge 33 upward so as to slidably support the lower surface of the chain plate 35 on the tip side of the chain link pin 34. This prevents the stock chain 19 from falling off the chain guide 28.

An engine cover 36 for covering the engine room is provided at the rear portion of the control device 9, and in order to prevent dust from the outside air sucked from the engine cover 36, double inner and outer dust-proof nets 37, 38 are provided. . The inner dustproof net 38 is attached to the outer dustproof net 37 or the net frame 40 by bolts 39. The outer dust-proof net 37 has a coarse mesh like an expanded metal, and the inner dust-proof net 38 is fine. These engine covers 36
An engine radiator, a radiator fan 41, and the like are provided on the inner side of.
