Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a nonter feeding device in a threshing machine.

(Prior art) In a conventional threshing device for a harvester, a feeding device provided with a star foil or an endless belt with lugs was attached to the grain culm discharge side, and this was forcibly driven to rotate, and the feeding device was attached to the rear of the device. The grain culm was being sent to the grain culm passageway in Notztar.

(Problems to be Solved by the Invention) The disadvantage of the known example is that the grain culms taken out from the grain culm outlet by the feeding device of the threshing machine are small bundles at a time.
Even if this is sent to the grain culm passage, the bundles are too small, so the grain culm passage has to wait until about 3 to 5 bundles have accumulated, at which time the grain culm gets caught on the star foil or conveyor. A phenomenon of clogging was observed.

In other words, it is difficult to separate them because they are continuously supplied one after another.

(Means for solving the problem) In order to prevent this drawback, it is necessary to allow a certain amount of grain culm to accumulate in the portion of the star foil or the endless belt with lugs, and after a certain amount has accumulated, the grain culm is not introduced into the grain culm passage. The present invention provides a grain culm supply port 5 on the front surface of a threshing device 3 which has a grain culm supply port 5 on the - side and a grain culm takeout port 6 on the other side.
A grain culm supply chain 7 and a grain culm lever 8 are provided for taking out the grain culm supplied to the grain culm from the grain culm take-out port 6, and a knotter is provided outside the grain culm take-out port 6, and the grain culm take-out port 6 A freely rotating endless belt 13 is hung between the grain culm passage 16 of the knotter and the grain culm passage 16 of the knotter, and lugs 14 are protruded from the outer periphery of the endless belt 13 at wide intervals to store several bundles of grain culms 15. The grain culm 15 taken out from the grain culm outlet 6 by the grain culm supply chain 7 is bundled into several bundles and is intermittently supplied to the grain culm passage 16 as a knotter feeding device in a threshing device. It is something.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a running vehicle body, and a pair of left and right crawlers 2, 2 are provided at the bottom of the running vehicle body 1.
will be established. A known threshing device 3 is provided on the upper part of the traveling vehicle body 1. Although this embodiment is a harvester, it can also be applied to a combine harvester.

On the supply side of the threshing device 3, a supply table 4 is provided on which the harvested grain culm is placed. Numeral 5 is a grain culm supply port, and 6 is a grain culm take-out port. On the front side of the threshing device 3, there is a grain culm supply chain 7 that supplies grain from the grain culm supply port 5 and pulls it out from the grain culm take-out port 6. Install grain culm rod 8.

Reference numeral 9 denotes a rotating shaft on the side of the grain culm outlet 6 of the grain culm supply chain 7. A sprocket is attached to the rotary shaft 9, and the grain culm supply chain 7 is wound around the sprocket. However, a separate pulley 10 is attached to the one-rotation shaft 9, and
A shaft 11 is provided at a position away from the rotating shaft 9, a pulley 12 that rotates idly is attached to the shaft 11, and the endless belt 13 is looped around the pulley 10.12 so that the endless belt 13 also rotates idly. Lugs 14 are provided on the surface at slight intervals. Therefore, the grain culms 15 are successively supplied between the grain culm supply chain 7 and the grain culm lever 8.
The grains move from the grain culm supply port 5 to the grain culm takeout port 6, are pulled out at the grain culm takeout port 6, and are transferred to the endless belt 13.
Since the endless bell 13 has a structure in which it is hung around 2 and rotates idly, the endless bell 13 does not rotate even if one bundle or one bundle is supplied between the lug 14 and the next lug 14. The number of bundles that must be supplied before the lug 14 is rotated varies depending on the design, but normally the lug 14 will be pushed by the grain culm 15 only after around three bundles have been supplied. It moves little by little and is ejected. Therefore, the endless belt 13 and the lugs 14 also serve as the temporary stop device 6.

16 is a known grain culm passage, 17 is a T projection, 18 is a packer, 19 is a needle, and 20 is a binding part provided above the grain culm passage 16.

(effect) Next, we will discuss the effect.

The engine installed at a desired position is started, the crawler 2 is rotated until it reaches the vicinity of the group of grain culm bundles packed like a mountain, the machine is stopped, and the grain culm bundles are piled up on the feeding table 4. .

When the stacked grain culm bundles are fed one bundle at a time from the grain culm supply port 5, they are held between the grain culm supply chain 77 and the grain culm lever rod 8 by the rotation of the grain culm supply chain 7, and are then fed into the grain culm supply port 5. The grains are threshed in the threshing chamber of the threshing device 3, and are supplied one bundle at a time between the lugs 14 attached to the outer peripheral surface of the endless belt 13. However, the distance between the lugs 14 is wide, and the endless bell +13 is a pulley that spins idly.
12 and pulley 12 and rotates idly, so it does not move at all even if about one bundle is supplied.

Therefore, 2 bundles and 3 bundles will be stored between them, and when about 3 to 5 bundles are stored, the lug 14 will finally rotate, and the next lug 14 will be seen on the side of the grain culm extraction port 6. By repeating this operation, the wrapped grain culm 15 will be supplied to the grain culm passage 16, and the backer 18 will feed the T protrusion 17 with 1
It is pressed together and bound together.

(Effects) Conventional threshing equipment for harvesters has a feeding device with a star wheel or an endless belt with lugs attached to the grain culm discharge side, which is forcibly driven to rotate, and a nozzle attached to the rear of the feeding device is installed on the grain culm discharge side.・Grain culms were being sent to the grain culm passage in the center. The drawback of the above known example is that the grain culms taken out from the grain culm take-out port by the feeding device of the threshing machine are small bundles at a time, so even if these are fed into the grain culm passage, the east side is too small, so the grain culms are In the culm passage, it was necessary to wait until about 3 to 5 bundles were accumulated, and at that time, a phenomenon was observed in which the grain culms got caught on the star foil or the conveyor and became clogged.

However, in the present invention, the grain culms supplied to the grain culm supply port 5 are taken out from the grain culm take-out port 6 on the front surface of the threshing device 3, which is provided with the grain culm supply port 5 on the - side and the grain culm take-out port 6 on the other side. Grain culm supply Che77
A grain culm lever 8 is provided, and a knotter is provided outside the grain culm outlet 6, and an endless belt 13 is provided between the grain culm outlet 6 and the grain culm passage 16 of the knotter.
The grain culms 1 for several bundles are hung around the outer periphery of the endless belt 13.
The grain culms 15 taken out from the grain culm outlet 6 by the grain culm supply chuck 77 are collected into several bunches and are intermittently passed through the grain culm passage. 1
Since the belt is used as a knotter feeding device in a threshing machine, the endless belt 13 is wrapped around the pulleys 12 and 12 which rotate idly, so even if about one bundle is fed, It does not move at all. Therefore, when about 3 to 5 bundles are stored, the lug 14 finally rotates and the next lug 14 faces the grain culm outlet 6, so that the grain that is wrapped in the grain culm passage 16 is not moved at all. Culm 15. This has the effect of preventing known defects.
