Description

[Detailed description of the invention] The present invention is a grain recovery device for a combine harvester configured to supply and store threshed grains in a grain storage tank by a grain lifting device of a threshing device. Specifically, the main tank for storing grains is placed on the side of the threshing device, and the grains transported from the threshing device are dropped and supplied into the main tank from a discharge pipe provided above the main tank. The present invention relates to a grain collecting device for a combine harvester.

According to this kind of combine grain collecting device,
Since the main tank for storing grains is placed on the side of the threshing device, the grain storage tank is placed on the top of the threshing device, for example, as described in Japanese Patent Application Laid-open No. 11749/1983. It has the advantage of being able to lower the center of gravity of the machine compared to conventional machines, allowing for stable running, but on the other hand, since the tank is placed on one side of the machine, it is possible to increase the threshing storage capacity and increase the capacity of the tank. If the grain storage tank is made as large as possible in order to reduce the frequency of transporting the grain stored in the tank and improve work efficiency, as the number of stored grains increases, the center of gravity of the aircraft will shift significantly toward the tank, and On the ground, the traveling gear located below the tank sank into the ground, causing it to skew.

As a means to prevent such skewing, for example, as described in Japanese Utility Model Application Publication No. 120931/1983, the upper part of a tank placed on the side of the threshing device is extended above the threshing device. It is known that the movement of the center of gravity of the machine due to the storage of grains is suppressed as much as possible, but the grains are stored sequentially from the tank part located on the side of the threshing device, and the grains are stored in this tank part. Since the structure is such that grain cannot be stored in the tank located above the threshing device until the entire tank is full, there is a drawback that skewing is likely to occur until the entire tank is full.

The present invention was developed in view of the above-mentioned circumstances, and while increasing the amount of grain stored and improving work efficiency, the weight of the left and right sides of the machine due to the supply of grain into the tank from the beginning of work is The purpose is to minimize loss of balance and enable safe driving.

The feature of the present invention to achieve the above object is that the main tank for storing grains is placed on the side of the threshing device, and the grains transported from the threshing device are delivered to a discharge port above the main tank. In a combine harvester grain collection device configured to drop and feed into a main tank from a cylinder, a sub tank is provided across the top of the main tank and the top of the threshing device, and a sub tank is provided on the top side of the sub tank. An opening for receiving the discharge tube is formed, and an opening for dropping grain supply and a shutter for receiving grain are formed on the lower surface side, and the opening for dropping grain is separated from the shutter by a partition wall. The secondary tank is located closer to the main tank in the direction in which the main tank and the threshing device are arranged side by side; and a second position where the shutter is located above the main tank, and the shutter is configured to be able to be opened and closed in the second position, With this configuration, the following actions and effects are achieved.

That is, the secondary tank is configured so that its shutter portion is positioned between the upper part of the main tank and the upper part of the threshing device so that it can move laterally, and the grains stored in the secondary tank are removed from the upper part of the main tank. By moving it to the top of the threshing device, it is possible to suppress the movement of the center of gravity of the machine toward the main tank as the number of grains stored in the main tank increases from the beginning of work, and as a result, the conventional structure described at the beginning It is now possible to run stably without causing the aircraft to skew due to the movement of the center of gravity.

In addition, by moving the part of the secondary tank where the shutter is located above the main tank to supply grain to the secondary tank, or by making it possible to discharge grains from the secondary tank into the main tank, the discharge cylinder can be The grain supply structure from the main tank to both the main and subtanks can be simplified, and as a whole,
It has now been possible to provide a grain collecting device that can run stably while increasing the amount of stored grain and improving work efficiency.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

A threshing device 2 is mounted on a traveling machine body equipped with a crawler traveling device 1, and a threshing device 2 is mounted on the front part of the traveling machine body. A pre-harvest treatment section 3 and a control section 4 are arranged side by side, and a grain collecting device 5 is arranged behind the control section 4 to form a combine harvester.

To configure the grain collecting device 5, as shown in FIG. An auxiliary tank 7 is disposed between the upper part of the threshing apparatus 2 and the upper part of the threshing apparatus 2, and one end of the first material collection screw conveyor 8 of the threshing apparatus 2 is passed through the lower part of the main tank 6 to form the main tank 6.
A conveyance mechanism 9 that extends outwardly and supplies the conveyed grains from the threshing device 2 from above the main tank 6 is interlocked to this projecting end.

The conveyance mechanism 9 connects a grain lifting cylinder 10 equipped with a screw conveyor so as to be rotatable and fixed around the axis of the first item collection screw conveyor 8, and has a grain discharge port 11a at the tip, and A conveying tube 11 equipped with a screw conveyor is connected to the upper part of the grain lifting tube 10, and a grain discharging tube 13 equipped with a shutter 12 is connected to the portion of the conveying tube 11 located above the main tank 6. It is configured as follows.

Finally, by closing the delivery shutter 14 provided at the top of the screw conveyor 8 located at the bottom of the main tank 6 and opening the shutter 12 of the discharge cylinder 13, the grains from the threshing device 2 are sequentially removed. By dropping and supplying the grains into the main tank 6, opening the carry-out shutter 14, and closing the shutter 12 of the discharge tube 13, the stored grains in the main tank 6 are removed from the machine through the distal end discharge port 11a of the conveyance tube 11. It is configured so that it can be carried out.

The sub-tank 7 has a lid 19 covering the upper surface side.
A long hole-shaped opening 20 is formed to receive the grains discharged from the grain discharge tube 13, and an opening 21 for dropping and supplying grains and a shutter 18 for receiving grains are formed on the lower surface side. The opening 21 for dropping feed is located closer to the main tank 6 side than the shutter 18 in the direction in which the main tank 6 and the threshing device 2 are arranged side by side, with the partition wall 22 in between.

This sub-tank 7 is connected to the shutter 1.
The temporary storage section 7a provided with the shutter 18 is located above the threshing device 2, the opening 21 is located above the main tank 6, and the temporary storage section 7a provided with the shutter 18 is located above the main tank 6. The opening 21 is located above the main tank 6, as shown by the imaginary line in FIG.
A wheel body 16 is supported at its lower end that acts on a guide rail 15 connected to the upper part of the main tank 6 in order to move it laterally to a second position located on the side opposite to the threshing device 2. At the same time, a hydraulic cylinder 17 is interposed between the main tank 6 and the sub tank 7.
