JPH0613663Y2 - Outer cover structure of threshing part in combine - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the outside of the threshing part in a combine in which a safety cover and the like are openably and closably attached to the outside of the threshing part, which is the outside of the entire machine body. Regarding the cover structure.

[Conventional technology]

Conventionally, a reaping unit is installed in front of the threshing unit that houses the handling cylinder and sorting device in the machine longitudinal direction, and a driving unit, a paddy treatment unit, and an engine unit are provided on one side of the threshing unit. In the combine harvester, one safety cover was attached to the outer side of the threshing part, which is the outer side of the fuselage,
In case of maintenance inspection of each part of the sorting device or if the No. 2 reduction cylinder is clogged, you have to remove the large safety cover to perform maintenance inspection of each part, or disassemble the No. 2 reduction cylinder for processing. It had a cover structure with poor workability.

[Problems to be solved by the invention]

The present invention can quickly and easily deal with such maintenance and inspection, and if the No. 2 reduction cylinder is clogged, simply open and close each part, and the outside of the threshing part is compact and has a good safety cover. The structure is provided, and the structure is provided so as to be suitably implemented.

[Means for solving problems]

Therefore, in the present invention, the transmission pulleys in the sorting device are arranged on the outer side of the threshing section on the side opposite to the paddy treatment section so as to be able to conduct the belt, and the second reduction cylinder on the outer side of the belt. Is vertically installed so as to be openable and closable, and a front cover and a rear cover, which can cover the conductive pulleys and belts, are openably and closably attached to the front and rear sides of the No. 2 reduction cylinder, respectively.

[Action]

Therefore, the outer side of the threshing part, which is the outer side of the entire machine body, can be covered with the front cover, the second reduction cylinder and the rear cover, and the front cover and the rear cover can be independently opened and closed to maintain the inner side of each. It becomes possible to perform inspections and the like, and if the No. 2 reduction cylinder is clogged, the No. 2 reduction cylinder itself can be opened and closed without removing the cover, and quick and easy countermeasures can be taken.

〔Example〕

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

Fig. 2 shows a side view of the combine. The thresher (A) is mounted on the machine supported by both crawlers (13).
In front of (A), reel (14), cutting blade (15), scraping auger
(16), a cutting section (B) equipped with a feeder (17), etc., and a paddy processing section consisting of a paddy tank (18) and a discharge auger tube (19) on the right side of the threshing section (A). (D) is installed in series, and the paddy processing unit (D)
A driving part (C) and an engine part (E) are arranged in front of and behind, and the structure is the same as the conventional structure.

The threshing section (A) has a screw-type handling cylinder (1) in the longitudinal direction of the fuselage mounted above the inside thereof, and below the crimping net (20) stretched below the handling cylinder (1), It consists of rocking sorter (7a), blower fan (3a), horizontal fan, compressed air fan (4a), first spiral conveyor (5a), second spiral conveyor (6a), dust exhaust fan (8a), etc. The sorting device (2) is arranged in the longitudinal direction of the machine body to have the same structure as the conventional structure.

Threshing section on the opposite side of front and rear paddy processing section (D), which is on the outside of the machine
On the outer side of (A), the front and rear air blower fans (3a) and the compressed air fan (4a)
a) 1st spiral conveyor (5a), 2nd spiral conveyor (6
a), input transmission pulleys (3), (4) for driving the drive eccentric wheel (7a) and the dust collecting fan (8a) of the swing sorting body (7a), respectively.
(5) (6) (7) (8) is projected and mounted on the shaft, and each transmission pulley is hung around each belt (9) that conducts from the input shaft (21), and the outside of the belt (9). The upper part of the No. 2 reduction cylinder (2), which is located at and slanted along the outer side of the threshing section (A), communicates with the upper side of the swing sorting body (7a) on the front side, Further, the lower part thereof is installed so as to communicate with the terminal side of the second spiral conveyor (6a).

The No. 2 reduction cylinder (10) that houses the spiral conveyor (10c) is divided into a semi-cylindrical inner cylinder (10a) and an outer cylinder (10b), and one side of the outer cylinder (10b) that is the outer side is divided. It is connected to one side of the inner cylinder (10a) via a hinge (22), and the other end of the outer cylinder (10b) that can be opened and closed is connected to the other end of the inner cylinder (10a) via each wing bolt (23). It is installed so that it can be detachably connected, and on the outside of the threshing part (A) on both the front and rear sides of the No. 2 reduction cylinder (10), the No. 2 reduction cylinder (1
The front cover (10) that can approach the front and rear of (0) and cover the transmission pulleys (3) (4) (5) and the belt (9), and the transmission pulley.
(7) and (8) and a rear cover (11) capable of covering the belt (9) are respectively attached so as to be openable and closable.

Therefore, the front cover (11), the second reduction cylinder (10), and the rear cover (12) are arranged side by side on the outer side of the threshing section (A), which is the outer side of the fuselage, to form a safety cover structure. ), The air blower fan (3a), the pressure air fan (4a) in the sorting device (2),
Maintenance and inspection of the No. 1 spiral conveyor (5a) can be performed, and by opening the rear cover (12), maintenance and inspection of the rocking sorting body (7a) and dust fan (8a) can be performed. If the return cylinder (10) is clogged, keep both covers (11) and (12) closed, remove the butterfly bolts (23), and attach the outer cylinder (10b) with the arrow (a).
If it is opened as shown by, it means that only the second reduction cylinder 10 can be opened and dealt with.

[Effect of device]

Thus, the present invention is compact and good because the front cover (11), the second reduction cylinder (10) and the rear cover (12) are arranged side by side on the outer side of the threshing section (A) which is the outer side of the machine body. A safe cover structure can be used, and when performing maintenance and inspection of the sorting device (2), the front cover (11) or the rear cover facing the required location can be used.
(12) Only one side needs to be opened, and the second reduction cylinder (1
If it is stuck in (0), you can deal with it by opening the No. 2 reduction cylinder (10) without opening both covers (11) and (12), and you can create a safety cover structure with good workability. It has the feature that it can be performed preferably.
