Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an elevator support device in a feeder house of a combine harvester, and more specifically, to an elevator support device in a feeder house of a combine harvester. This relates to the lower drum support device of the chain conveyor that transports the chain to the handling room.

Prior Art A lower drum support device for a chain conveyor in a feeder house of a conventional combine is located outside the side plate of the feeder house, and the lower drum moves up and down depending on the load.

Problems to be Solved by the Invention In the lower drum support device of the chain conveyor in the feeder house of a combine harvester as described above, since the lower drum support device is located outside the side plate of the feeder house, the culm easily gets entangled and mud adheres to it. Easy to do.

Therefore, there is a disadvantage that the support device for the lower drum cannot move up and down due to entangled shell culms and mud, and there is a disadvantage that the drum cannot move up and down depending on the load.

Means for Solving the Problems Therefore, the technical problem of the present invention is to provide a lower support device for a chain conveyor in a feeder house of a combine harvester without the adhesion of mud or entanglement of shell culms.

In order to solve this technical problem, the technical means of the present invention are:
The base of the arm that supports the lower drum of the elevator chain is elastically pivoted on the inside of the feeder house side plate, and upper and lower limit stoppers that the arm abuts are provided on the inside of the feeder house side plate to adjust one of the stoppers. It can be configured freely.

Effects of the Invention In the present invention, the base of the arm supporting the lower drum of the elevator chain in the feeder house is provided inside the side plate of the feeder house, so that the arm is covered by the side plate to prevent entanglement of the culm and adhesion of mud. Therefore, the vertical movement of the lower drum in response to the load will not be hindered due to entanglement of the shell culms or adhesion of mud.

Since the support device is provided inside the side plate of the feeder house, the structure can be replaced with a compact structure as a whole.

Example The embodiments shown in the drawings will be described below.

First, the entire screw type threshing machine will be explained.

In Figure 12, the crop is raked in by a raking reel (1) and cut by a cutting blade (2), and the cut crop is transferred from a raking auger (3) to a chain conveyor (5) in a feeder house (4). It is carried to the handling room (6) and the screw set handling cylinder (7
) is threshed.

The threshed grains fall from the receiving net (8) onto the oscillating sorting board (9) and are sorted.

The threshed grains are sorted on this swing sorting board (9), but only the long straw is carried toward the rear dust outlet.

In addition, the materials to be sorted on the oscillating sorting board (9) are sorted by the sorting air from the winnowing machine (11) or the sorting air from the blower fan (12), and the grains are sent to the second gutter (13); Gutter (14
), and the grains that fell on the spices (13) are transferred to the frying barrel (
16) to the paddy tank (17).

The second material is returned to the oscillating sorting board (9) through the thrower cylinder (18).

The culm discharge section of the threshing section as described above consists of the discharge vane (19) installed in the handling barrel (7) and the discharge port (20) of the casing (20).
21).

The present invention relates to an elevator support device in a feeder house (4) in a combine harvester as described above.

(22) is the upper drum of the chain conveyor (3);
3) is the lower drum of the chain conveyor (3).

The middle of the chain conveyor (3) is guided by chain guides (24) and (25) as shown in Fig. F.

The lower drum (23) is supported by an arm (26), and the arm (26) is connected to the feeder house (23) as shown in FIG.
4) is pivotally supported on the inner surface of the side plate (4a) by a shaft (27).

The pin (28) and arm (26) planted on the side plate (4a)
) and a pin (29) set up on the shaft (27).

The side plate (4a) also has the first arm (26) in between.
As shown in the figure, disk-shaped upper and lower limit stoppers (31) and (32) are attached to shafts (33 and 34), and the upper and lower limit stoppers
The shaft (33) of (31) is an eccentric shaft, and by rotating the disc-shaped upper limit stopper (31) about this shaft, the contact position with respect to the arm (26) is adjusted.

Therefore, the arm (26) is connected to the stopper (31) (32
) and moves in response to the load on the reaping section.

Since the support device for the lower drum (23) is thus provided on the inner surface of the feeder house (4), straw and mud will not adhere to the lower drum (23) and impede its vertical movement function.

In addition, the feeder house (4) can be attached to and removed from the machine, but in order to maintain sealing performance when attached to the machine, the upper cover (34) is attached with a seal rubber as shown in Figure 5.9.12. (35) is attached, and a sealing rubber (37) that abuts against the threshing supply table (38) is provided on the upper part of the bottom plate of the feeder house (4). In Fig. 6, (39) is the docking fitting for the feeder house of the reaping section, (40) is the scraping section drive chain sprocket, and its shaft (41) is connected to the cutting blade (2) via the continuously variable speed side brie (not shown). and the auger (3), and the bearing bracket (
42) and is supported by the side plate (4a) of the feeder house (4).

Also, (46) in Fig. 1 is the reaping drive chain, and (50)
) is its chain guide.

And the power is from the upper drum (22) to the chain (46)
The reaping drive chain sprocket (40) is driven via the. Next, numeral (43) shown in FIG. 7 indicates the top cover of the feeder house, and two lids may be provided as shown in FIG. 11.

Fig. 9 shows a different drive type for the scraping section, in which the sprocket (44) is driven from the upper drum (22) via the chain (46), and the sprocket (44) is driven via the chain (47). sprocket that drives the cutting blade)
(45) is driven, and tension is applied by a tension roller (48).

The tension roller (48) is supported by an eccentric shaft (49).

In FIG. 9, (16) is a cutter provided in the middle of the feeder house. Moreover, the one shown in FIG. 10 is provided with a pair of left and right elevators (5).

Furthermore, the reaping section drive chain guide (50) shown in FIG.
can be adjusted up and down with the metal fittings (51) along with other chain guides.
