Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a grain tank for a combine harvester that harvests and threshes culms.

(b) Prior art In general, combine harvesters that have a threshing device and a grain tank installed on the machine stand require maintenance of the threshing device and the transmission device between it and the grain tank from the grain tank side. From there, the grain tank was evacuated by rotating around a horizontal shaft at the bottom of the outside or a vertical shaft set up on the machine platform.

(c) Problems to be Solved by the Invention When the previously known grain tank has a large capacity, it becomes heavy and difficult to tilt, and as it is filled with grain, the center of gravity of the machine shifts There was a drawback that the left-right balance of the aircraft deteriorated significantly as it shifted to the side.

Furthermore, since the grain tank was a closed type, maintenance inside the tank was troublesome.

(d) Means for solving the problems The present invention increases the capacity of the grain tank by connecting the fixed tank on the threshing device to the movable tank provided on the machine base.
At the end of grain filling, the grain is stored in a fixed tank,
To prevent the left-right balance of the machine from deteriorating, and to maintain the parts between the threshing device and the grain tank in an open state, it is possible to easily tilt only the movable tank to solve the above-mentioned problem. Resolved the point.

(e) Operation When grains are filled into the grain tank using the grain lifting cylinder of the threshing device, they are first stored in the movable tank one after another, and when they reach the upper part of the threshing device, they are also stored in the fixed tank. When the shift of the center of gravity is most severe, the grain will be distributed between the mobile tank and the fixed tank on the thresher.

In addition, when tilting the grain tank in order to maintain the threshing device or the transmission device between it and the grain tank, all that is required is to release the connection with the fixed tank and rotate only the movable tank. Despite expanding the internal volume of the upper part of the tank,
Tilting outward or tilting back toward the threshing device can be easily performed.

Furthermore, when servicing the interior of the grain tank, not only the fixed tank but also the movable tank have openings, so maintenance can be easily performed from these openings.

(F) Current side To explain a combine harvester according to an embodiment of the present invention shown in the drawings, 1 is a threshing device mounted on one side of a machine base 3 having a traveling device 2, and in front of it is a reaping device. A pre-processing device 5 consisting of a shell 4 and a culm conveying device is installed, and a straw processing device such as a cutter 6 or a tying machine is installed at the rear, and a grain tank A is provided on the other side of the machine 3. is composed of a movable tank 7 and a fixed tank 8, and the movable tank 7 has its outer lower portion pivotably supported by support shafts 9, 9 to the front and back of the outside of the machine 3, and communicates with a V-shaped bottom plate. At the transfer end of the transfer spiral 11 housed in the box-shaped receiving trough IO, there is a grain frying thrower 1 whose intermediate and tip portions can be folded and which can tilt left and right when discharging grains.
The input pulley 13 which is connected to the input pulley 2 and fixed to the starting end side is the eighth
As shown in the figure, a tension pulley 16 is driven by an output 9-15 of a gear case 14 via a V-belt 17 attached thereto, and an input pulley 18 of the gear case 14 is driven by a pulley 13a of an engine 19 to a tarlatch pulley 2.
The movable tank 7 is driven via a V-belt 21 attached with a number 0, and a portion of the movable tank 7 corresponding to the fixed tank 8 is formed in an opening 7a.

The front part of the fixed tank 8 is screwed onto the threshing device l by a double-shaped mounting plate 22, and the rear wall plate 8b is fitted with a bottom plate 8c that is inclined toward the movable tank 7. It is provided on the threshing device 1 by being fixed to the cylinder 23 via the stay 24, and the base is rotatably inserted into the horizontal holding cylinders 25 and 25 attached to the front and rear surfaces of the fixed tank 8. The shaped connecting rod 26° 26 is connected to the horizontal notched grooves 29.2 of the supports 27, 27 fixed to the front and rear surfaces of the movable tank 7.
9, and when the tip is turned downward as shown in FIG. 5, it is locked.

Also, the openings of the movable tank 7 and fixed tank 8? a, 8
The front and rear side edges of a are tapered and overlapped as shown in FIG. The lower edge of the movable tank 7 is bent diagonally toward the inside of the movable tank 7, and overlaps with the lower slope of the protrusion 8d.

Furthermore, since the grain lifting cylinder 23 is inserted into the fixed tank 8 from the bottom plate 8c as described above, the grain lifting cylinder 23 is inserted into the fixed tank 8 from the bottom plate 8c as described above.
When the discharge port 3 is communicated with the wall plate of the grain tank, the internal volume of the grain tank can be expanded horizontally and forwardly, and the casing 30 at the top of the grain lifting cylinder 23 has a flat surface as shown in FIG. It has a fan shape that widens approximately 90 degrees toward the rear when viewed, and opens approximately 270 degrees toward both sides and the front, so that the grains can be released over a wide range by rotating the throwing blade 31 that is integrated with the grain-lifting spiral shaft. Since the bottom plate 8c is sloped downward toward the movable tank 7, the grains placed in the fixed tank 8 quickly slide down into the movable tank 7, making it difficult for the threshing device 1 to handle the grains. When the handling room cover 32 and cylinder cover 33 are opened as shown by chain lines in FIG. 2 to inspect and maintain the interior, the bottom plate 8c does not become an obstacle.

34 is a grain detection sensor attached to the fixed tank 8'', 35 is a viewing window with a transparent plate attached, 36, 37 is a cleaning port with a removable lid, and 38 is a threshing device 1 of the movable tank 7.
It is a link that can be folded in two and connects the lower part of the side to the machine base 3. When the movable tank 7 is tilted outward as shown in Fig. 1, it maintains its tilted posture, and when it is stood up, it can be folded up. It will be done.

In the above-mentioned combine harvester, the grains that have been harvested, threshed, and sorted from the husks are fried by the grain lifting cylinder 23, and the throwing blades 31 release the fried grains across the movable tank 7 and the fixed tank 8. The thrown grains in the fixed tank 8 flow down the bottom plate 8C and enter the movable tank 7, and after being deposited up to the lower edges of the openings 7a and 8a, the grains are transferred to the movable tank 7 and the fixed tank. The grains are deposited over a wide area covering both the movable tanks 7 and 8, and the left-right balance of the machine body is better than when only the movable tank 7 is filled with grains.

When loading the grains in the grain tank A onto the transport vehicle, the machine is moved to the transport vehicle, the grain thrower 12 is tilted to the side, the transfer spiral 11 is driven, and the shutter is opened to load the grains. Load onto the transport vehicle.

Furthermore, when servicing the threshing device L inside the grain tank A or the transmission device between it and the grain tank A, the connecting rod 26
．． 2ft horizontally and pushed toward the thresher 1 side to release it from the receivers 27, 27, and then tilt the movable tank 7 outward, the movable tank 7 and fixed tank 8
The opening is opened, and at the same time, the transmission device and the cleaning ports 36, 37, etc. of the threshing device 1 are exposed for maintenance.

When the maintenance work is completed, when the movable tank 7 is stood up and rotated, the openings of the movable tank 7 and fixed tank 8 will be opened. a,
The upper part, both side edges and lower edge of 8a are shown in Figures 3 and 4.
As shown in the figure, since the connection rod 2 is closely polymerized, the connection rod 2
8.28 is pulled out in a horizontal position, engaged with the cutout grooves 29.29 of the receiver 27.27, and rotated downward to connect.

(G) Effects of the Invention Since the present invention is configured as described above, by connecting the fixed tank 8 to the movable tank 7, the capacity of the grain tank A can be increased, and the grain filling is not possible. When the amount becomes large, the fixed tank 8 on the threshing device 1 is also filled to prevent the center of gravity of the machine from shifting to the side opposite to the threshing device 1 and tilting the machine to the side, thereby making it easier to operate. It is possible to improve the screening performance and sorting performance.

In addition, when maintaining the grain tank A, the threshing device 221, and the transmission device between them and the grain tank A, the demarcation tank 8 located at the farthest position from the tilting fulcrum remains attached to the threshing device 1. Only the movable tank 7 can be tilted easily and easily, and the grain tank A can also easily maintain the movable tank 7 and the fixed tank 8 from their openings.
