Description

[Detailed Description of the Invention] The present invention relates to a threshed grain storage structure for a combine harvester in which a threshed grain tank is provided to be freely swingable around a vertical axis.

The storage structure described above allows the threshing section to be inspected easily from the space perspective by pulling out the threshing grain tank from its cradle and opening the side of the threshing section located on the side of the tank. Conventionally, when pulling out a tank, the free end of the tank comes off the pedestal and simultaneously falls under its own weight, which causes the tank pivot to be deformed or damaged. The free end of the tank must be supported to prevent it from falling suddenly, and when storing the tank, the free end of the tank must be lifted up so that the free end, which is lower than the top of the pedestal, can be placed on the pedestal. This type of tank support operation made it difficult to pull out and store the tank.

The purpose of this invention is to prevent the free end of the tank from falling suddenly from the pedestal, and to allow the free end of the tank to be placed on the pedestal without the need for special support operations, allowing the tank to be pulled out or stored. The goal is to make work easier.

The characteristic configuration of the present invention is that in the above-mentioned threshed grain storage structure of the combine harvester, as the threshed grain tank is stored and swung on the pedestal, the free end side of the threshed grain tank is placed on the pedestal. This is because it has an inclined guide surface for lifting.

In other words, when the tank is pulled out, the free end side gradually falls down due to the receiving and guiding action of the inclined guide surface, and when the tank is simply swung toward the pedestal, the free end side is moved to the pedestal by the cam action of the inclined guide surface. Since it can be lifted upward, it is possible to prevent the free end of the tank from falling suddenly, and to eliminate the need for tank support operations to place the free end of the tank on the pedestal. By simply swinging the tank, the tank can be easily pulled out and stored on the pedestal without being damaged.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, a traveling machine base having a crawler-type traveling device 1, a driving part 2, and a driving part 3 is used to raise planted grain culms as the machine moves, and to reap and harvest the harvested grain culms. A pre-harvesting treatment section 4 is transported to the rear of the machine, a threshing section 5 handles the grain culm from the pre-harvesting treatment section 4, and the threshed straw from the threshing section 5 is discharged in a shredded state or in a long straw state. A tank 8 which stores the threshed grains supplied from the threshing part 5 by the conveying device 7, and a screw-type grain lifting device 9 which carries out the grains inside the tank 8, is provided with each waste straw processing section 6. A combine harvester is constructed by providing a traveling machine stand with a threshed grain storage section having each of these sections arranged at a location located laterally of the threshing section 5 and behind the driving section 2.

The threshing grain tank 8 is rotatably attached to the bracket 10 of the traveling machine base and the support 5a of the threshing section 5 via the base end 9a of the grain hoisting device 9, and the whole is placed close to the threshing section 5. The base end of the grain lifting device can be placed in a stored state where it is placed on top of the pedestal 11, and in a pulled out state where the free end side protrudes outward from the pedestal 11 to the front side of the machine so that the threshing section can be inspected easily. The portion 9a is configured to be able to be oscillated and switched around the vertical axis P. Furthermore, when the threshed grain tank 8 is placed in the stored state, a removable lock pin 13 is inserted into the cylinder 12 fixedly installed on the free end side of the tank 8 and the pedestal 11, and A fixing plate 14, which is attached to the wall of the threshing section so as to be swingable around the vertical axis, is removably fitted and locked onto a bolt 15 protruding from the upper part of the free end side of the tank 8. It is constructed to lock the swinging of the tank 8.
When the threshing tank 8 is in the pulled-out state, the free end side of the tank 8 is grounded by lowering the stand 16, which is attached to the lower part of the tank 8 so as to be able to swing up and down. It is configured to be supported.

The grain discharge screw 17 installed in the threshed grain tank 8 and the output shaft 18 on the machine side thereof are interlocked and connected by a power transmission wire 19 which can transmit rotational force and can freely bend and extend.
By bending and stretching, the threshed grain tank 8 can be pulled out without removing the transmission system for the screw 17.

As shown in FIGS. 3 and 4, a bent plate 22 that forms an inclined guide surface 21 that acts on the end of the pedestal 11 is attached to a bracket 20 fixed to the bottom of the free end of the threshed grain tank 8. When the tank 8 is pulled out, the supporting and guiding action of the inclined guide surface 21 on the tank 8 causes the free end of the tank to gradually descend under its own weight as it comes off the pedestal 11. When storing the tank 8, simply by swinging the tank 8 toward the pedestal 11, the free end of the tank is lifted onto the pedestal by the cam action of the inclined guide surface 21.

The stopper 23 shown in FIG.
2 to position the storage of the grain tank 8. Further, the rotary handle 24 shown in FIGS. 3 and 4 is for rotating the base end 9a of the distal end portion 9b of the grain lifting device 9, and is connected to the gear type rotation operation mechanism 26. On the other hand,
A rotating shaft 27 extending through the tank 8 is interlocked with a transmission chain 28.

The inclined guide surface 21 may be formed into a flat surface as shown in FIG. 5, or may be formed into a flat surface as shown in FIG.
It may be provided on the first side. Further, as shown in FIG. 6, the roller 25 may be configured to be in contact with the guide surface 21. In this case, the tank 8 can be moved onto the pedestal 11 very smoothly. This makes the storage process easier and more convenient.
