Abstract

PROBLEM TO BE SOLVED: To increase the capacity of a grain tank, as its center of gravity is kept low, by inclining a cylinder for elevating grains from the thresher to the grain tank toward the grain tank side so that it may not disturb the grain- discharging auger to be contained. SOLUTION: The threshing unit 2 and the grain tank 3 for containing the threshed grains 3 are mounted on the chassis 1 in parallel and a spiral grain- lifting cylinder 4 for the threshing unit 2 is made apart from the wall of the threshing machine so that the outlet at the top end of the cylinder comes over the grain tank 3 and inclined upward and outside, while the lower wall of the outlet 5 of the grain tank is bulged on the side of the spiral grain-lifting cylinder 4.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a combine grain tank.

[0002]

2. Description of the Related Art The frying structure constituted by a spiral frying tube between a threshing device and a Glen tank is unlikely to interfere with a grain-raising auger that grinds from the Glen tank to the outside of the machine. It is intended to maintain the grain storage capacity of the Glen tank as large as possible.

[0003]

According to the present invention, a threshing device 2 and a grain tank 3 for accommodating the threshing grains are juxtaposed on a chassis 1 and a spiral fried grain barrel 4 of this threshing device 2 is provided at the upper end of the barrel. The threshing machine wall 6 with the discharge port 5 looking over the Glen tank 3
Is provided away from and inclined toward the upper outside,
The lower wall 7 of the discharge port 5 of the grain tank 3 is configured as a combine grain tank in which the lower wall 7 is bulged toward the spiral frying cylinder 4 side.

[0004]

The functions and effects of the present invention The threshed grains to be threshed and sorted by the threshing device 2 are accommodated in the side grain tank 3 from the discharge port 5 through the spiral fried grain cylinder 4. The discharge port 5 at the upper end of the fried food barrel 4 is separated from the threshing machine wall 6 to the outside, but the lower wall 7 of the grain tank 3 can be bulged so as to approach the fried food container 4 side. Therefore, the capacity of the Glen tank 3 can be maintained large and the center of gravity can be lowered.
Moreover, the storage position of the grain-removing auger for grain-removing from the grain tank 3 can be lowered and set to the return position of the grain-removing device 2 on the side of the grain tank 3, which hinders maintenance such as opening and closing of the grain-removing chamber cover of the grain-removing device 2. It's hard to be.

[Example] The combine is a threshing device 2 in a self-defining form,
The grain culm transfer port 1 is provided along one side of the threshing chamber 9 in which the handling cylinder 8 is mounted.
A feed chain 11 and a sling rod 12 are provided outside 0, and threshing is carried while conveying the grain culm cut by the reaping device 19 in front. Below the threshing net 13 in the threshing chamber 9, there is an oscillating sorting shelf 14 for oscillating and sorting by receiving threshing, a sardine 15 and a suction duster 16 for wind-selecting this sorted material, and receiving the sorted grain. A first gutter 17 for transferring and a second gutter 18 for receiving and transferring a second object are provided.

Such a threshing device 2 is provided on one side of a chassis 1 having a crawler traveling device so that a feed chain 11 is located outside, and a grain tank is provided on the side opposite to the feed chain 11. 3 is installed. The engine E, the cockpit 20, the cockpit 21 and the like are arranged in front of the Glen tank 3. A spiral fried grain cylinder 4 is provided in communication with the end of the first trough 17 of the threshing device 2 on the side of the gren tank 3, and the first trough 17 receives the grains sent by the rotation of the spiral and is fried. Grain from the discharge port 5 at the upper end to the Glen tank 3
Supply inside. The fried-grain barrel 4 is provided in an inclined state with the lower end thereof being close to the threshing machine wall 6 side and the upper end being located outside the Glen tank 3 side. In addition, the spiral fried grain cylinder 22 that is continuously provided at the end of the second trough 18 receives the second grain collected by the second trough 18 and returns it to the entrance side of the threshing chamber 9 to re-produce it. It is a threshing process. Since the upper end of the spiral fried food container 22 is provided in an inclined posture in the front-rear direction toward the entrance side of the threshing chamber 9, the spiral fried food container 22 is brought closer to the threshing machine wall 6 side with respect to the first fried food container 4. Are provided.

The grain tank 3 has a recess 23 formed by recessing the threshing machine wall 6 into the tank so that the frying cylinder 4 can be fitted therein. The lower wall 7 on the threshing device 2 side of the grain tank 3 including these recesses 23 is bulged toward the threshing machine wall 6 side to increase the amount of grains accommodated. A transfer gutter 24 is formed at the bottom of the Glen tank 3 along the front-rear direction, and a transfer spiral 25 is provided. By driving the transfer spiral 25, the accommodated grains can be transferred rearward.

A vertical auger 26 is rotatably provided on the rear side of the Glen tank 3 by a motor, and a horizontal auger 27 is integrally connected to the upper end of the vertical auger 26.
By driving the spiral 25 of the grain tank 3, the augers are interlocked with each other so that the grains can be conveyed and discharged from the discharge port 28 to the outside of the machine. The horizontal auger 27 can be raised and lowered with respect to the vertical auger 26 by a telescopic cylinder, and the discharge height can be adjusted.

Reference numeral 30 denotes an auger receiver provided on the frame of the threshing device 2, which forms a Y-shape and supports the storage posture of the lateral auger 27. At this time, the horizontal auger 27 is in the lower limit position and in a substantially horizontal state, and is supported so as to extend in the front-rear direction at a position closer to the Glen tank 3 of the threshing device 2 and lower than the upper end of the fried cylinder 4 in the front-rear direction. It In this state,
The threshing cover 31 on the threshing chamber 9 can be rotated upward around a hinge 32 on the side closer to the Glen tank 3 so as to be opened at an appropriate angle.

5 and 6, the difference from the above example is that
The Glen tank 3 is configured to be separable into a lower tank 33 made of sheet metal and an upper tank 34 made of synthetic resin that is attached to and detached from the lower tank 33. 4, the lower tank 34 has a bottom opening 43 that can be opened by rotating the transfer gutter 24 at the bottom downward, and axially mounts a spiral 25 extending in the front-rear direction to form a funnel shape. Is configured. Reference numeral 35 is a hinge for opening and closing the transfer gutter 24, and 36 is a handle for this rotation operation.
Reference numerals 37 and 38 are reinforcing plates for connecting the front and rear side plates 40 and 41 of the lower tank 33, and 39 is a bolt for mounting the upper tank 34.

The Glen tank 3 is constructed such that it can be rotated outward around the hinge 42 at the rear end. Front and rear side plates 40, 41 of the lower tank 33
The upper side plate 44 is integrally formed on the upper side, and the front and rear wall portions of the upper tank 34 can be fixed to the upper side plate with bolts. The rear plate 41 is integrally formed with an auger metal 45 and a lower hinge metal 46 into which the rear end of the spiral 25 is fitted, and an upper hinge metal 47 is provided at the upper end of the upper side plate 44. Hinge metal 46,4
7 is supported by upper and lower hinge metals 51 and 52 provided on an auger metal 48 attached to the rear part of the chassis 1 and a support frame 50 of the vertical auger 26, and between the upper hinge metals 47 and 52 and the lower hinge metal 47 and 52. Hinge metal 46, 51
By inserting the hinge pins 42 into the spaces, the Glen tank 3 can be swung outward around these hinge pins 42. At this time, the glen tank 3 is attached to the elbow-shaped auger metal 48 fixed to the chassis 1 side.
The side metal 45 can be opened and closed together with the internal spiral 25.

A lower end of the vertical auger 26 is supported by an auger metal 48 so that the vertical auger 26 can rotate freely.
Supported by The rotation of the spiral 25 of the Glen tank 3 causes the spirals in the vertical auger 26 and the horizontal auger 27 to rotate together, so that the grains contained in the Glen tank 3 are transferred to the transfer gutter 2.
4, the vertical auger 26 and the horizontal auger 27 are transferred through the metal 45, the auger metal 48, and the like, and discharged from the discharge port 28.

7 and 8 are different from the above example in that
On the upper side of the threshing cover 31 on the transfer port 10 side, the slidable rod 12 is provided.
The hook 34 that locks the closed posture of the threshing cover 31 and the arm 55 are integrally provided rotatably around the hook shaft 56, and the engaging portion 57 that engages the hook 54 is provided on the threshing frame side. It is provided. Arm 55
Has a guide rod 58 for slidingly guiding the upper surface of the root of the threshing transfer grain culm along the outer side of the slidable rod 12. The guide rod 58
Is pushed up from below, the hook 54 is disengaged from the engaging portion 57, and the threshing cover 31 can be opened upward together with the slinging rod 12. Therefore, when the operator's arm A is erroneously attempted to be sandwiched between the slidable rod 12 and the feed chain 11, this guide rod is pushed up to release the hook B, the hook 54, and the slidable rod 12. Can be floated and the danger can be removed.
