Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-cullet-type combine harvester in which threshing is performed by an axial-flow type handling cylinder.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned all-culm throw-in type combine, only one handling cylinder is provided in a threshing device as disclosed in, for example, Japanese Utility Model Publication No. 4-136024.

[0003]

By the way, in the above-mentioned conventional structure, since only one handling barrel for threshing treatment is provided, the grain culm which can be normally introduced into the threshing apparatus to enable threshing treatment. Since the amount is limited to the ability to perform threshing processing with only one of the handling cylinders, there is a limit to performing high-speed mowing work to enhance the processing capacity. Had to considerably increase the size of the entire machine even considering the transmission structure to various devices. The present invention has been made in view of the above-mentioned circumstances, and it is possible to increase the threshing treatment capacity without making the overall size of the machine excessively large, and the transmission mechanism to various devices can be compactly placed. The purpose is to provide a type combine.

[0004]

In order to achieve the above-mentioned object, a whole culm throw-in type combine according to the present invention is provided with a pair of left and right handling barrels for threshing cut culms, which are arranged side by side on the left and right sides of the threshing section. The grain tank is arranged on one side of the threshing unit, and the sorting mechanism is arranged below the gullet handling cylinder near the gren tank, and the gullet handling barrel is far from the gren tank. A transmission mechanism for transmitting power to various devices of the machine body is disposed in a space below the space. The operation and effect of this characteristic configuration are as follows.

[0005]

In other words, since the cut culms are treated by the pair of left and right handling barrels of the threshing device, the threshing ability is higher than that of the conventional one in which only one handling barrel is used. Further, since the transmission mechanism is arranged by utilizing the space portion formed below one of the handling cylinders of the gull which is far from the Glen tank, a special space portion is not newly provided for installing the transmission mechanism. May be.

[0006]

Therefore, even if the mowing work is performed at a higher speed than the conventional one, that is, even when the vehicle speed is higher than the conventional one, a large amount of two grain culms are introduced into the pre-mowing processing section. Since the threshing process is divided into two parts and each threshing process is carried out by different handling cylinders, the work efficiency of the mowing threshing work becomes extremely high because the cutting work can be sufficiently performed at high speed. Furthermore, as a structure for that purpose, since a pair of handling cylinders are provided by allocating to the left and right, the lateral width of the aircraft may be slightly larger than before, but it is possible to sufficiently suppress the longitudinal length and vertical height of the aircraft and Since the mechanism can be arranged by utilizing the space below one handling cylinder, the entire machine can be made compact for threshing performance.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an all culm input type combine according to the present invention. This combine equips the machine body 2 supported by a pair of left and right crawler traveling devices 1, 1 with the threshing section 3, the boarding control section 4, the Glen tank 5 and the like, and at the front of the machine body 2, the horizontal axis core. The cutting pretreatment unit 6 is mounted so that it can swing up and down around it.

The pre-cutting processing section 6 includes a rotary reel 7 for scraping the planted culms backward and a reaping device 8 for cutting the planted culms.
, A belt conveyor 9 for conveying the cut grain culm to the rear, an auger 10 for moving the conveyed corn grain to the left side, and a reaping device for rearing the corn grain on the left side by the auger 10. It is composed of a feed conveyor 11 that is moved toward the No. 3 and a cutting unit frame 12 that supports these devices. The cabin 13 including the boarding control unit 4 is located on the right side of the feed conveyor 11 in a plan view, and a door section 14 for allowing the operator to enter and exit is provided on a lateral side of the cabin 13. ing. The lower part of the cabin 13 has a width narrower than that of the upper part in order to secure a space for raising and lowering the mowing pretreatment section 6 on the left side part thereof, and an operator seated on the seat 15 operates the control levers. The upper portion of the cabin 13 is relatively wide for easy operation.

The threshing section 3 is provided with a pair of left and right handling chambers 16 and 16 for introducing the cut culms transported by the wide feed conveyor 11, and the handling barrels 17 are provided in the handling chambers 16 and 16, respectively. , 17 are installed so as to be rotationally driven around a longitudinal axis. Each handling cylinder 17,1
Receiving nets 18 and 18 are provided so as to leak down the treated material along the outer periphery of the lower and inner sides of 7. Further, below the handling room 16 on the right side, the receiving nets 18 and 1 are provided.
Sorting device 19 for sorting the leaked material from 8
Are installed. Below the left handling chamber 16, an inclined guide surface 20 is provided for guiding a substance leaked from the left receiving net 18 to the sorting device 19. Then, behind the both handling chambers 16 and 16, there is disposed a waste straw cutter 21 for shredding the discharged waste straws discharged from the rear end portions of the both handling chambers 16 and 16 and discharging them to the field. is doing.

On the right side of the threshing unit 3, a driving unit 22 including an engine, a transmission case, etc., and the Glen tank 5 are juxtaposed in front and rear. A counter shaft 23 for transmitting power from the driving unit 22 to the reaping pretreatment unit 6 and the sorting mechanism 19 is extended to the left side in a state that it constitutes a drive shaft of the Karako 24 in the sorting mechanism 19, and the inclination It is interlockingly connected to a belt transmission mechanism 25 as a transmission mechanism arranged in a space S formed below the guide surface 20. The belt transmission mechanism 25 is used to transmit the sorting mechanism 19 to the first item recovery screw 26 and the like. Sorting mechanism 1
The first item sorted by 9 is the first item recovery screw 2
6 is transported to the right side, and is fed to the inside of the grain tank 5 by the lifting device 27 that is connected to the transport end portion of the first object recovery screw 26 that extends outward from the threshing unit 3. I am trying. The left side wall 28 facing the threshing unit 3 of the grain tank 5 is formed so as to be shared with the right side wall of the threshing unit 3, and the stored grain is stored at the bottom of the Glen tank 5 formed in the shape of a lower pool. Bottom screw 29 for discharging
The vertical screw 30 is provided in a state where the vertical screw 30 is connected to the end of conveyance of the bottom screw 29, and the horizontal screw 31 for discharging grain is connected to the upper end of the vertical screw 30.

With the above structure, the cut culms are sorted to the left and right and threshed by the pair of left and right handling cylinders 16, 16, respectively. Therefore, even if the amount of cut culms is considerably increased, the threshing process can be sufficiently performed. By arranging the belt transmission mechanism 25 for the sorting mechanism 19 and the like in the space S below the left handling cylinder 17, the overall size of the machine body is kept compact so as not to be as large as possible. Even in the state, it is possible to perform work with an increased mowing work speed.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
