Description

[Detailed Description of the Invention] The present invention relates to a delivery device for delivering paddy in a grain tank mounted on a combine harvester to a truck or the like.

In order to eliminate the bagging work of paddy on the combine, recent combine harvesters are equipped with a grain tank, and the harvesting and threshing work is performed while the threshed paddy is stored in this grain tank, and the paddy is stored in the grain tank. When the grain tank is full, the harvesting and threshing operation is stopped, the combine is driven to the edge of the ridge, and the paddy in the grain tank is sent to a truck etc. through a paddy delivery tube with a built-in screw. During delivery, it may not be possible to bring the combine harvester close to the truck due to the ridges, etc. in the field, so the length of the paddy delivery tube with a built-in screw that extends from the grain tank of the combine must be as long as possible. However, since this paddy delivery tube is stored on the top surface of the combine during reaping and threshing operations, its length cannot be greater than the total length of the combine.

In this invention, the length of the paddy delivery tube for sending out the paddy inside the grain tank can be increased by configuring it so that it can be bent into two pieces on the top surface of the combine. .

The present invention will be explained below with reference to the drawings of the embodiments. In the drawings, reference numeral 1 indicates a combine harvester body supported on a frame 3 having a pair of left and right traveling crawlers 2. A threshing unit 4 is provided on the right side, and operating units such as an operating column 5 and a seat 6 are provided on the right side, and a weeding body 8, a grain culm lifting mechanism 9, a cutting blade mechanism 10, and a grain culm conveying mechanism 11 are provided on the front side of the machine body 1. Reaping pre-processing section 7 consisting of etc.
However, the lower frame 12 protrudes forward from the fuselage 1.
and an upper frame 13 that protrudes forward from the threshing section 4. A grain tank 14 is mounted on the right side of the upper surface of the fuselage 1 and behind the seat 6. The paddy threshed by the threshing section 4 is sequentially fed into the paddy 14 using a hoisting cylinder (not shown).

A paddy transport cylinder 15 is inserted into the grain tank 14 at a position close to the seat 6 so that its axis is perpendicular and can freely rotate around the axis. A gate is installed at the bottom of the grain tank so that the paddy in the grain tank 14 can enter, and the upper end of the paddy transport cylinder 15 is inserted into the grain tank 1.
4 protrudes from the top surface. On the other hand, on the upper surface of the combine, a paddy delivery cylinder 16 whose axis intersects with the axis of the paddy transport cylinder 15 is arranged so as to extend in the front-rear direction of the combine, and the base end of the paddy delivery cylinder 16 is connected to the paddy transport cylinder 16. The paddy sending cylinder 16 is connected to the upper end of the conveying cylinder 15 so as to be able to move up and down freely, and a hydraulic cylinder 17 is provided between the paddy sending cylinder 16 and the paddy conveying cylinder 15 to operate the paddy sending cylinder 16 upward and upward. , Also, the paddy conveying cylinder 15
There are screws 1 inside and inside the paddy delivery tube 16, respectively.
8 and 19 are inserted, and both screws 18 and 19 are inserted.
are configured to move dynamically relative to each other at the connecting portion of both cylinders 15 and 16, and to send out the paddy from the paddy delivery cylinder 16 in the grain tank 14 by rotationally driving both of them with one power source. . Of the two levers 20 and 21 provided near the operating section of the combine harvester, one lever 20 is a lever for raising, raising, and turning the paddy delivery tube 16, and the other lever 21 is a lever for raising, raising, and turning the paddy conveying tube 16. Both screws 18, 1 in 15 and in the paddy delivery cylinder 16
This is for turning on/off the rotation of number 9.

On the upper surface of the combine, an extended paddy delivery pipe 22 is connected to the tip of the paddy delivery pipe 16.
are arranged in the front and back direction of the combine, and a paddy discharge port 23 is provided at one end of the extended paddy delivery tube 22 on the front side of the combine, while the other end of the extended paddy delivery tube 22 on the rear side of the combine is connected to the paddy delivery tube. 16 is connected with a hinge pin 24 at the tip thereof so that it can be bent at a position where it is connected in a straight line to the paddy delivery tube 16 and at a position where it is bent in two relative to the paddy delivery tube 16. In addition, a screw 25 is built in the extended paddy delivery tube 22, and the screw 25
5 is provided with a clutch 27 that engages with a clutch 26 in the screw 19 inside the extended paddy delivery tube 22 when it is linearly joined to the paddy delivery tube 16. Also, code 28,
29 is when both cylinders 16 and 22 are joined in a straight line,
This is a detachable engagement means that maintains this state.

In this configuration, when the extended paddy delivery tube 22 is linearly joined to the paddy delivery tube 16, the paddy delivery tube 1
The length from the connection base end of No. 6 to the grain tank 14 to the paddy discharge port 23 of the extended paddy delivery pipe 22 is the length of the paddy delivery pipe 16 plus the length of the extended paddy delivery pipe 22. In this case, the extended paddy delivery tube 22
By arranging the extended paddy delivery tube 22 so as to extend in the front and back direction of the combine harvester, the length of the extended paddy delivery tube 22 can be made substantially equal to the total length of the combine. The grain tank of the paddy delivery pipe 16 is located near the rear of the combine harvester, and is arranged so as to extend from this position to the rear of the combine harvester, and the other end of the extended paddy delivery pipe 22 is connected to the tip thereof. The length from the base end connected to the paddy pipe 14 to the paddy discharge port 23 of the extended paddy pipe 22 is longer than the entire length of the combine by the length of the paddy pipe 16.

Therefore, when the paddy in the grain tank 14 is discharged from the paddy discharge port 23 at the tip of the paddy discharge tube 16 and the extended paddy discharge tube 22, the distance from the combine harvester to the paddy discharge port 23 is significantly extended. This makes it possible to ensure that paddy can be delivered from the grain tank of the combine harvester to the truck etc. even in cases where the combine harvester cannot be sufficiently close to the truck etc. due to the relationship with the ridges in the field or the side ditches in the field. This has the effect of improving the paddy delivery work.
