Description

[Detailed description of the invention] "Field of industrial application" The present invention is a grain tank device for a combine harvester in which grain culms harvested in a reaping part are threshed and sorted in a threshing part, and only the sorted grains are stored.

"Prior Art" For example, there is a grain tank described in Japanese Utility Model Application Publication No. 59-31833 in which a grain transporting device of a grain tank and a winnowing shaft on the side of the machine are driven and connected by a belt.

``Problems to be solved by the invention'' However, in the case of the above means, when the grain tank is opened to the outside of the machine around the vertical axis or stored inside the machine, the belt must be closed each time. The removal and installation operations are troublesome and time consuming.

``Means for Solving the Problems'' Therefore, the present invention supports a grain tank for storing threshed grains so as to be rotatable to the outside of the machine body through a vertical shaft, and also provides a drive input for the tank. The drive output section is connected to the drive output section of the machine so that it can be attached and detached with a single touch.

"Function" According to the present invention, when the grain tank is opened to the outside of the machine body or stored inside the machine body, the drive coupling part can be easily disconnected or connected with a single touch, Open storage work to the outside or inside of the machine becomes easy, and various maintenance inspections become convenient.

"Embodiment" An embodiment of the present invention will be described below in detail based on the drawings.

Fig. 1 is a cross-sectional explanatory view of the grain tank, Fig. 2 is an overall side view, and Fig. 3 is a plan view of the same. 4 is a threshing section which is fixedly supported on the truck frame 1, 4 is a threshing section with a feed chain 5 stretched on the left side and a handling cylinder 6 is built in, and 7 is supported so as to be movable up and down in front of the machine 3 via a hydraulic cylinder 8. a reaping section including a cutting blade 9 and a grain culm conveying mechanism 10;
11 is a straw removal cutter portion facing the end of the straw removal chain 12 connected to the end of the feed chain 5;
13 is an engine unit that drives each part of the combine;
Reference numeral 14 designates a grain tank for storing grain to be taken out from the threshing section 4 by facing the grain lifting cylinder 15, and reference numeral 16 designates a driver's cab equipped with a driver's seat 17 and a driving operation section 18. The grain culm is harvested and the harvested grain culm is threshed in the threshing section 4.

As shown in FIGS. 4 and 5, the grain tank 14 further includes a grain lateral feed auger 19 at the bottom, and a vertical feed auger 20 at the rear for vertically feeding the grains from the lateral feed auger 19. A horizontal discharge auger 21 is provided at the top to take out the grains from the vertical feed auger 20 to the outside of the machine, and the grain tank 14 can freely rotate outward around the auger cylinder 22 of the auger 20, which is the vertical axis. The lower end shaft portion 23a of the drive transmission case 23 of the horizontal feed auger 19 and the vertical feed auger 20 is connected to the bearing member 24 of the machine base 3, and the intermediate portion of the vertical feed auger 20 is connected to the front wall of the engine section 13. The grain tank 14 is rotatably supported by the cylinder support member 25.
The front side is configured to be openable to the outside. In addition, the grain tank 1 is connected to the lock plate 26 of the timing stand 3 of the grain tank 14 through a lock pin 27.
4 is removably fixed to the fixing holder 28 of the grain tank 14, and the locking fitting 31 of the inner wall of the grain tank 14 is removably fixed to the locking fitting 29 of the inner wall 4a of the threshing section 4 via the lock pin 30. It is configured to maintain the position of the tank 14.

Further, the engine 13 of the engine section 13 is connected to an input shaft 33 which is a drive input section that is interlocked and connected to the lateral feed auger 19 via a pair of bevel gears 32.
The output shaft 35, which is the drive output part of the intermediate drive case 34 on the machine side that transmits the a output, is connected to the butt clutch 36.
The tank 14 is connectably connected via the tank 14.
When the input shaft 33 and output shaft 3 are stored or opened,
5 can be coupled or uncoupled with a single touch. The coupling direction of the clutch 36 is such as to allow rotation of the grain tank 14, and the structure is such that the coupling or disengagement can be performed without any trouble when the tank 14 is stored or opened.

By the way, the right inner wall surface 1 of the grain tank 14
4a includes the lower limit, middle limit, and
In addition to providing upper limit amount sensors 37, 38, 39,
An indicator 40 for displaying these storage amounts is provided on the upper part of the front wall 14b of the grain tank 14.
The connection cords 41 of these sensors 37, 38, 39 and the indicator 40 are arranged along the right inner wall surface 14a of the tank, and are inserted through a cord insertion hole 42 opened in the rear wall 14c of the tank near the auger cylinder 22. The power supply side of the cord 41 is led out to the outside of the tank 14, and the auger cylinder 2 of the tank 14 is
When the cord 41 is rotated about 2, the amount of displacement of the cord 41 is suppressed without pulling or loosening the cord 41. In addition, 43 is the auger tube 2
This is an auger cylinder of a horizontal discharge auger 21 which is connected and supported in an undulating and rotatable manner.

This embodiment is configured as described above, and the grains harvested by the reaping section 7 and threshed by the threshing section 4 are stored in the grain tank 14, and the augers 19, 20, 21 are driven when necessary. By doing so, the grains in the grain tank 14 are taken out of the machine.

Therefore, when inspecting the drive transmission system from the engine 13a between the threshing section 4 and the grain tank 14, the lock pins 27 and 30 are unlocked and the lock pins 27 and 30 are unlocked as shown in the phantom lines in FIG. The grain tank 14 is rotated outward around the auger tube 22 to open it, and as a result, the surplus space around the drive transmission system is expanded, making inspection work easier. When storing or opening the tank 14, the drive input shaft 33 of the tank 14 and the drive output shaft 35 of the machine can be easily connected and connected by one-touch operation by abutting or releasing the abutment of the clutch 36. Uncoupling is performed.

In the above-mentioned embodiment, the drive input shaft 33 of the tank 14 and the drive output shaft 35 of the machine are connected by the butt clutch 36, but the input shaft 33 draws around the auger cylinder 22. Any structure may be used as long as it can tolerate the rotation locus, and either a friction method in which the opposing surfaces of the shafts 33 and 35 are brought into surface contact, or a meshing method such as a coupling method may be used.

"Effect of the invention" As is clear from the above embodiments, the present invention has the advantage that the grain tank 14 for storing threshed grains is connected to the vertical shaft 2.
2 so as to be rotatably supported to the outside of the fuselage,
Since the drive input section 33 of the tank 14 is connected to the drive output section 35 on the machine side so that it can be attached and detached with a single touch, the drive input section 33 of the tank 14 is connected to the drive output section 35 on the main machine side so that it can be attached or detached with a single touch. This makes it extremely easy to attach and detach the tank 1.
Tank 1 to facilitate the opening and storage work of Tank 4.
It has remarkable effects such as being able to improve the efficiency of maintenance and inspection work around the four parts.
