Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for receiving paddy threshed in a self-travelling combine harvester into a paddy bag on the combine harvester.

A self-traveling combine harvester continuously performs reaping and threshing work while placing the threshed paddy on top of the combine and sequentially packing it into paddy bags, so the reaping and threshing work, that is, the combine harvesting work, is performed continuously for a long time. In order to be able to do this, it is necessary to install a large number of paddy receiving hoppers on the combine harvester so that the combine can store as much threshed paddy as possible and pack it into a large number of paddy bags. However, when a plurality of paddy receiving hoppers are used, the threshed paddy from one grain hoisting cylinder must be uniformly distributed and supplied to the paddy receiving hoppers.

Therefore, conventionally, as shown in Japanese Utility Model Application Publication No. 50-112586, a plurality of paddy receiving hoppers are arranged in a row, and a screen extending horizontally along the row direction of the hopper row is installed in the upper part of the hopper row. A Yukon conveyor is provided, and the paddy sent from one grain hoist is distributed and supplied to each paddy receiving hopper by the screw conveyor.

However, providing the distribution screw conveyor in the upper part of the hopper row not only significantly complicates the structure and increases the weight of the combine, but also makes it difficult to drive the distribution screw conveyor. Since the combine harvester requires a certain amount of power, the engine installed in the combine must have a considerable amount of horsepower, and by providing this distribution screw conveyor, each rice receiving hopper can be Since the effective volume (volume that can store paddy) of the paddy is reduced by the capacity of the screw conveyor, in order to store a predetermined volume of paddy, each paddy receiving hopper must be made larger by the capacity of the screw conveyor. This is not the case.

The present invention provides a combine harvester with a paddy receiving tank in which a plurality of paddy receiving hoppers each having a paddy outlet at the lower part are arranged in a row with their upper parts communicating with each other, and a paddy receiving tank is provided in the fuselage of the combine. A paddy discharging port for the paddy to be sent is placed above one end of the paddy receiving hopper row in the paddy receiving tank, and the paddy from the paddy discharging port passes through the top of each paddy receiving hopper and is discharged toward the other end of the paddy receiving hopper row. By connecting the paddy in such a way that the paddy is input in order from the farthest paddy receiving hopper, it is possible to distribute the rice to each paddy receiving hopper without using a distribution screw conveyor, thereby solving the conventional problem. In addition to the above, the present invention also enables the flow of paddy from each paddy receiving hopper without causing a bridging phenomenon within the paddy receiving hopper, and also enables the paddy to be stored in each paddy receiving hopper. This makes it easy to pack paddy into paddy bags.

The present invention will be explained below with reference to drawings of embodiments. In the drawings, 1 denotes a pair of left and right traveling crawlers 2.
2 shows a machine whose rear part is pivoted by a pin 3 and is raised and lowered around the pin 3 by a link mechanism 4 or a hydraulic cylinder at the front, and a threshing section 5 is mounted on the upper surface of the machine 1, Further, the front part of the machine body 1 is equipped with a reaping pre-processing section 6 and a conveying device 8 for collecting the grain culms harvested in the reaping pre-processing section 6 and sending them to the feed chain 7 in the threshing section 5. . Furthermore, on the upper surface of the fuselage 1, an operating column 9, a seat 10, an engine built-in cover 11, and a grain removal part 12 are provided in this order from the front along one side in the direction of travel.

Reference numeral 13 denotes a paddy receiving tank provided in the grain removal section 12, and the paddy receiving tank 13 includes a plurality of paddy receiving tanks (two in this embodiment) each having a paddy removing pipe 14 with a valve 15 at the lower end.
The funnel-shaped paddy receiving hoppers 16 and 17 are connected in a line along the direction of movement of the combine with their upper parts communicating with each other. The inner wall plate 13a on the side and the outer wall plate 13b on the side farther from the threshing section 5 are both formed vertically, and each of the hull removal pipes 14 is formed on the outer wall plate 13b.
At the lower part of the paddy removal pipe 14, the side wall plate 14b on the side farther from the threshing part 5 is the outer wall plate 13a.
Installed in a position that is approximately in line with the

In addition, the paddy receiving hopper 17 located at the rear of the combine has its falling plate 17' extended into the paddy receiving hopper 16 located forwardly, so that the volume of the rear paddy receiving hopper 17 is equal to that of the front paddy receiving hopper. Hopper 1
6, that is, the volume of the front paddy receiving hopper 16 is larger than that of the paddy bag 18 attached to the paddy outlet 14.
If it is for one bag, the capacity of the rear paddy receiving hopper 17 is formed to be an integral multiple of the capacity of the paddy bag 18, so that the capacity is for two bags, and the front paddy receiving hopper 16 is provided with an overflow pipe 23. It is provided.

Numeral 19 is a grain lifting cylinder with a built-in screw 20 for sending the paddy threshed by the threshing section 5 to the rice receiving tank 13.The upper end of the grain lifting cylinder 19 is equipped with an impeller 21 for discharging the paddy. A built-in paddy outlet 22 is provided, and this paddy outlet 22 is connected to the front paddy receiving hopper 1.
The paddy is connected to the upper part of the front side plate 16' of No. 6 so that the paddy from the paddy outlet 22 is discharged backward through the upper part of the front paddy receiving hopper 16 and the rear paddy receiving hopper 17. The lower part of the inner wall plate 13a of the receiving tank 13 is formed into an inclined side wall 13c which is inclined toward the side wall plate 14a of each of the paddy removal pipes 14 on the side closer to the threshing section.

In this configuration, the paddy threshed in the threshing section 5 is conveyed upward in the grain lifting cylinder 19 by the rotation of the screw 20, and by the rotation of the impeller 21 provided at the upper part, the paddy is delivered to the paddy receiver through the paddy outlet 22. tank 1
However, the paddy discharged from the paddy outlet 22 into the paddy receiving tank 13 is
Since the structure is such that the second paddy is discharged from the front paddy receiving hopper 16 toward the rear paddy receiving hopper 17 along the hopper row, the paddy is discharged from the paddy discharging port 2 first.
Enter the rear paddy receiving hopper 17 at a location farther than 2,
When the rear paddy receiving hopper 17 is full, the rice is distributed to the front paddy receiving hopper 16 in front of it, so that rice can be distributed in order from the rear paddy receiving hopper along the direction of movement of the combine.

In addition, in order to ensure that the paddy from the paddy outlet 22 reaches the rear paddy receiving hopper 17 at a location farther from this, the direction of discharging the paddy at the paddy outlet 22 should be directed diagonally upward, or the direction shown in the figure should be In this way, the tip of the top plate 22' at the paddy outlet 22 inside the paddy receiving tank 13 may be formed diagonally upward at an appropriate angle θ.

In this way, each paddy receiving hopper 16,1
7 is full of paddy, remove the paddy from the lower end of the paddy pipe 1.
Attach a paddy bag to 4 and open the valve 15 to allow the paddy in the paddy receiving hopper to flow out into the paddy bag 18. When the paddy bag is full of paddy, close the valve 15 and transfer this paddy bag 18' containing paddy to each paddy. After removing the paddy from 14 locations, the paddy is loaded onto the loading platform 24 provided at the rear of the paddy receiving tank 13, and after attaching another empty paddy bag 18 to each paddy discharging pipe 14, the valve 15 is opened. Then, the paddy inside each paddy receiving hopper is taken out.

When the paddy in each paddy receiving hopper 16, 17 flows out from the paddy removing pipe 14, the paddy removing pipe 14 in each paddy receiving hopper is connected to the paddy removing pipe 14 at the lower part of the outer wall plate 13b of the paddy receiving tank 13. The side wall plate 14b on the side farther from the threshing part 5 in 14
is provided at a position substantially in line with the outer wall plate 13b, while the lower part of the inner wall plate 13a in the paddy receiving tank 13 is inclined toward the side wall plate 14a on the side closer to the threshing part of each of the paddy removal pipes 14. By forming it on the side wall 13c, it is possible to prevent the bridging phenomenon of rice grains from occurring within each rice receiving hopper.

That is, the paddy removal pipe 14 is provided at a position close to the threshing section 5, and there is also an inclined surface between the side wall plate 14b on the side farther from the threshing section 5 and the outer wall plate 13b of the paddy receiving tank 13. When a hopper is formed, the volume of the paddy in each paddy receiving hopper is gradually reduced from both sides as it flows down along the slopes on both the left and right sides, so the surface is rough and contains moisture, making it difficult for particles to slip together. Because it is becoming
In the middle of the flow, the paddy is bridged in an arch shape and the outflow of paddy from the paddy removal pipe 14 is stopped. Outer wall plate 13b in
At the lower part of the paddy removal pipe 14, the side wall plate 14b on the side farther from the threshing part 5 is the outer wall plate 13b.
On the other hand, the lower part of the inner wall plate 13a of the paddy receiving tank 13 is placed in a position substantially in line with the
When formed on the inclined side wall 13c that slopes toward the direction a, the outer wall plate 13 in the rice receiving hopper
The paddy located near b flows straight down vertically toward the paddy removal pipe 14 located directly below it, and there is a large speed difference between the paddy and the paddy flowing down along the inclined side wall 13c. Due to this speed difference, the tendency to crosslink in an arch shape is broken, and no crosslinking phenomenon occurs.

Although the embodiments have been described above, the present invention is arranged such that a plurality of paddy receiving hoppers each having a paddy removal pipe at the lower part are arranged in a line adjacent to the threshing section mounted on the body of the combine with their upper parts communicating with each other. An array of paddy receiving tanks is provided, and a paddy outlet for paddy sent from the threshing section of the combine is placed at the top of one end of the paddy receiving tank in the direction of the row of paddy hoppers, and the paddy from the paddy outlet is connected to each paddy receiver. The hopper is connected to the other end of the row of paddy receiving hoppers through the upper part of the hopper, and the outer wall plate on the side far from the threshing part of the paddy receiving tank is formed in a vertical shape. Each paddy outlet is provided at the lower part of the wall plate so that the side wall plate on the side far from the threshing part of the paddy extracting pipe is substantially in line with the vertical outer wall plate, and A paddy receiving device for a combine harvester, in which the lower part of the inner wall plate on the closer side is formed into an inclined side wall that is inclined toward the side wall plate on the side closer to the threshing section in each of the paddy removal pipes, the paddy receiving device for the combine harvester can be distributed and supplied to each paddy receiving hopper without using the conventional distribution screw conveyor, so the structure is significantly simpler and lighter than the conventional one, and the paddy receiving tank can be reduced. It can be made smaller, and less power is required to distribute paddy to each paddy receiving hopper, reducing the power burden on the combine harvester's engine.

Moreover, the paddy extraction outlet in each paddy receiving hopper is
The side wall plate on the side far from the threshing part of the paddy extracting pipe is installed so as to be substantially in line with the vertical outer wall plate, while the lower part of the inner wall plate on the side closer to the threshing part in the paddy receiving tank By forming the pipe with an inclined side wall that slopes toward the side wall plate on the side closer to the threshing part, bridging of paddy in each paddy receiving hopper can be reliably prevented when the paddy flows out of each paddy receiving hopper. , the paddy in each paddy receiving hopper can be continuously and smoothly flowed out, and in addition, the paddy outlet in each paddy receiving hopper is formed so that the side wall plate on the side far from the threshing part of the concerned paddy extracting pipe is a vertical outer wall plate. Since the paddy removal pipe is installed in a substantially straight line, the space at the bottom of the paddy receiving tank is larger than when the paddy removal pipe is installed closer to the threshing section, making it easier to bag the paddy. At the same time, it is possible to check at a glance whether or not the paddy bag is attached to the paddy removal pipe, thereby reducing the chance of paddy spilling due to improper attachment of the paddy bag. Combined with the fact that there is no cross-linking phenomenon, the efficiency of paddy removal work can be significantly improved.
