Description

[Detailed description of the invention] Industrial applications The present invention relates to a paddy tank structure in a combine harvester.

Conventional technology Conventionally, in a combine constructed by connecting the upper end of the paddy dumping port of the grain lifting cylinder extending from the threshing part to the inner side of the upper part of the paddy tank, the entire gj tank was rotated toward the outside of the machine. A model with a structure that can be removed by moving it outward is seen in Japanese Utility Model Application Publication No. 53-163244. When performing maintenance on the side parts, the structure is such that only a small amount of space is actually taken up and it is difficult for workers to enter.

Problems to be Solved by the Invention In this invention, only the lower part of the paddy tank is removed without removing the entire tank, and the upper part of the paddy tank connected to the grain lifting cylinder remains fixed. , it is easy to separate and connect with transmission related parts, and it is also small and can be separated for easy removal.
The present invention is provided with a structure that allows good maintenance of the paddy tank and its surrounding parts.

Means for Solving the Problems Therefore, in the present invention, the paddy tank is vertically divided into a partial tank and a lower tank that communicate with the paddy dumping port, and the lower tank can be taken out to the outside of the machine. It is constructed by being detachably connected to the lower part of the upper tank.

Function: With this configuration, only the lower tank can be removed, and the separation and connection of the transmission-related parts is also easy, and the tank can be opened wide and sufficiently, making it possible to perform maintenance on the paddy tank and its surrounding areas. It will be possible.

Example Next, the embodiment shown in the drawings will be described.

Figure 2 shows a side view of the combine harvester, in which a reaping section (0) is installed at the front of the machine supported by crawlers (3), a threshing section (B) is installed at the rear of the machine, and a threshing section (B) is installed at the front right side of the machine. A control column (5) and a seat (6) are erected in front and behind the constructed step (4), and an engine part (7) is installed at the rear, making it similar to the conventional structure.

- A paddy tank (A) is constructed above the machine base (8) which is the rear part of step (4), and the paddy tank (A) is constructed by an inclined dividing line (L) where the outer side of the machine body is the upper part of the slope. It is divided into an upper tank (a) and a lower tank (&2), and the threshing section (B) is located at the inside upper part of the smaller upper tank (a1).
The upper end side paddy dumping port (2) of the grain lifting cylinder (1) extending further is connected to connect the upper tank (aO), and the lower tank (a2
) is freely rotatably supported on both support pieces (91 (9)) erected on the outside upper part of the machine base (8) via the shaft αQ0Q, and the upper tank (a1) and lower tank 02) A connecting piece (bolt u2) is inserted into the connecting piece (111) that spans between the connecting pieces to connect and fix the connecting piece.

A discharge spiral conveyor I is installed in the gutter α3 located below the inside of the lower tank (a2), and the lower tank 0
The terminal end side of the discharge spiral conveyor I is mounted in a shelf U51 connected to the lower side of the rack, and a pulley α mark is fitted to the end of the conveyor shaft 0→ extending from the shelf T151. There is a discharge auger cylinder on the upper end that can be rotated freely. The mallet part t151 is attached to the lower part of the vertical grain frying auger cylinder α3 in which the
A transmission pulley ■ is installed on the side of a transmission gear case ■ fixed to the side of the grain auger cylinder 1g+ so that the inlet side of the auger cylinder 1g+ can be transmitted to the grain auger cylinder 1g+. At the same time, a belt is removably hung on the transmission pulley CiD and the Boo 1) - [+61, and the input pulley protruding from the transmission gear case 1 to the other side is attached to the transmission pulley on the engine side.
It is constructed by hanging a belt 5 extending from.

Therefore, when working with a combine harvester,
As shown in the figure, the upper tank (,) with the sloping dividing line (2)
and the lower tank (join ail, insert bolt 0 M to connect and fix, and fix the shelf part convex) by fixing with Ill dl and hanging belt a from both pulleys 〇9■,
Paddy tank (
A) Paddy is put in and stored inside A), and when the paddy is discharged, it is moved from the discharge spiral conveyor r1a to the fried grain auger a.
m and is discharged from the discharge auger cylinder Uη.

In addition, when performing maintenance, inspection, maintenance, or cleaning in or around the inside of the paddy tank (A), remove the belt @ and tighten the bolts.
1! When J as and - are removed and the lower tank (a) is rotated outwards around the axis QOQO, both the shelf part t151 and the lower tank (-=1 will fall outward) as shown in Figure 4. As a result, the lower part of the upper tank (il1) is widely opened, and maintenance work can be performed.

In addition, the lower tank separated from the inclined dividing line (L) is
One of the lower tanks has a structure with a discharge spiral conveyor at the bottom, similar to the previous embodiment, and the other lower tank has a paddy outlet for discharging paddy into the paddy bag below. It is also possible to construct a structure having the following.

Effects of the Invention As described above, in the present invention, since the paddy tank (A) is divided into upper and lower parts, the lower tank (a2) can be easily removed outwardly, and furthermore, the lower tank 02) is small, so it can be easily attached and detached. In addition, since only the lower tank (a) can be attached and detached, the connection with the grain lifting cylinder (1) side can be left as it is, and the separation and connection structure with the transmission system can be constructed without complicating the structure. Since the lower part can be opened widely, the structure allows maintenance of the paddy tank (A) and its surroundings to be carried out well, and has the advantage of being compact and suitable for implementation.

Claims (1)

[Claims] The upper end of the paddy dumping tube (1) extending from the threshing part (B) (
2) is configured by connecting the paddy tank (A) to the upper inner side of the paddy tank (A), and the paddy tank (A) is connected to an upper tank (a_1) and a lower tank (a_2) that communicate with the paddy dumping port (2). ), and the paddy tank structure is characterized in that the lower tank (a_2) is rotatably connected to the lower part of the upper tank (a_1) so that it can be taken out to the outside of the machine body.
