Description

[Detailed description of the invention] A grain take-out part consisting of a hopper or the like is provided on the side of the threshing part mounted on the machine stand, and a grain tank is mounted over the grain take-out part and above the threshing part. The outer part of this grain tank is pivotally connected to the outer upper part of the grain removal part so as to be tiltable up and down, and the upper part of the grain lifting cylinder is configured to be separable, so that the grains lifted by the grain lifting cylinder can be removed. After filling the paddy bag hanging below the grain take-out part and the grain tank and replacing the paddy bag, the grain tank is tilted upward and the grains in the grain tank are removed from the grain take-out part. If the paddy bags are filled after the process, the machine height can be made as low as possible, and a large amount of grain can be stored, making it possible to work continuously for a long time, improving work efficiency. be able to.

However, when the grain tank is raised, grains overflow from the upper division of the grain barrel and fall, and a swash plate extending from a hopper-shaped grain removal part catches the grains. If the grains are to be merged into the take-out portion, the angle of inclination of the swash plate becomes gentle, making it difficult for the grains to flow down, resulting in a drawback that the grains accumulate near the dividing portion of the grain lifting cylinder.

In this invention, the grains flowing out from the divided part of the grain barrel when the grain tank is raised are guided out by an auxiliary hopper separate from the grain removal part, and the grain is taken out in an open state to receive the grains. The purpose is to prevent grains from flowing out of the machine or from accumulating at the bottom of the divided part of the grain lifting cylinder by filling the paddy bag suspended on the machine body side from the paddy bag facing below the machine. be.

The embodiments shown in the drawings will be explained in more detail below.
Reference numeral 1 denotes a threshing section mounted on one side of a combine machine stand 3 having a traveling device 2, and on the other side of the threshing section 1, there are a hoisting tube 4, a plate wall, a supporting frame 5, and a supporting metal 6. A hopper-like grain take-out section 7 having four funnel-like take-out lowers a is attached to the lower part thereof at 6'.

Reference numeral 8 denotes a flat grain tank whose one end is tiltably pivoted to the upper outer end of the grain take-out section 7 by a support shaft 9, and which is mounted over the grain take-out section 7 and the threshing device 1 when descending. On the support frame 5, hanging rods 11 for hanging a large number of rice bags 10 are provided to protrude outward.

Further, the upper part of the grain lifting cylinder 4 is divided into upper and lower parts at a portion corresponding to the bottom plate of the grain tank 8, and the upper part is separated, and the separating part 4a is attached to the bottom plate of the grain tank 8. The casing 14a of the swing thrower 14 is integrally attached to the upper part thereof.

Furthermore, the upper part 4b' of the helical shaft 4b, which is divided by the part corresponding to the bottom plate of the grain tank 8, has its upper end supported by the casing 14a, and the top plate part of the discharge port of the casing 14a is shown in FIG. As shown, it is constructed with an overflow plate 14a' that can be opened and closed, so that when the grain tank 8 becomes full, when wet grains clog the discharge port, or when the small motor When the control unit for intermittently driving the grain tank 13 fails, the accumulated grains push up the overflow plate 14a' and overflow, and as this progresses further, the helical shaft provided on the top plate of the grain tank 8 4
The arc-shaped lid 8' centered at b is opened and pushed out, thereby preventing damage to the shaft joint, transmission mechanism, etc. if the grain lifting cylinder 4 becomes clogged.

An auxiliary hopper 15 that surrounds the grain lifting tube 4 is provided directly below the separation part of the grain lifting tube 4, and a flexible tube 16 made of rubber or the like connected to the lower part of this auxiliary hopper is connected to the lifting tube 4. It is inserted into a spare paddy bag 10' suspended from a rod 11.

17 is a hydraulic cylinder 21 whose upper part is pivotally supported on the support frame 5, and the upper end of the piston rod 17' is connected to the rod 1.
7'' to the bottom plate of the grain tank 8.

Reference numeral 18 denotes a switching valve which is supported by a valve shaft 18' between the inner and outer take-out lower a*7a', and a guide plate 18b is attached to the tip of the lever 18a fixed to one end of the valve shaft 18'. A set bolt 18c is provided which is inserted into the arc-shaped long hole of
When the thumb screw 18d is loosened and set by rotating it to the position shown by the solid line in Fig. 6, the grains flow out from the inner and outer take-out lowers a and 7a', and when set to the position shown by the dotted line, the grains flow out from the inner take-out lowers al and 7a. / is closed and the water flows out only from the outer take-out lowers a and 7a.

In addition, in the drawing, 19 is a shutter, and 20 is an upper cover of the threshing section 1.

In the above-mentioned device, the grains lifted by the grain lifting cylinder 4 are first thrown toward the grain removal section 7 by the rotating thrower 14, and when an assistant is on board, the switching valve 19 is turned on as shown in FIG. The paddy bags 10 are placed facing outward as shown by the solid lines, and are replaced every time the paddy bags 10 are full.When no assistant is on board, the switching valve 19 is retracted as shown by the dotted lines. 10
, 10... are full, the thrower rotates each time the detector 21 detects grains filled and deposited in the grain tank.
14 is sequentially and intermittently rotated toward the unfilled side to fill the entire grain tank 8.

Then, the full paddy bags 10, 10 are replaced, the shutter 18 is opened, and the grains in the grain tank are transferred to the paddy bags 10, 10.
When the grain tank 8 is raised by the hydraulic cylinder 17, the grains in the grain tank are transferred to the paddy bags 10, 10.
flows into.

At this time, since the upper part of the grain lifting cylinder 4 is attached to the grain tank 8, the upper part of the grain lifting cylinder 4 is separated, and the grains falling from inside and grains overflowing from the lifting cylinder 4 are sent to the auxiliary hopper. 15
It flows into the spare paddy bag 10'.

After taking out the grains, the grain tank 8 is lowered.

Since the present invention is constructed as described above, when the tank section is tilted upward to take out the grains filled in the tank section, or when the threshing section is driven by mistake while the tank section is raised, etc. The entire amount of grains flowing down from the separating part of the grain barrel can be reliably collected into the paddy bag by an auxiliary hopper, and the grain removing part 7 does not need to be extended to the separating part of the grain lifting barrel, and is configured with a steep slope. Because of this, there is no accumulation or clogging of grains when taking out the grains.
