Description

Detailed Description of the Invention (A) Industrial Application Field The present invention provides a grain tank for a combine harvester with an auxiliary grain tank that protrudes by rotating to the left and right in order to increase the storage capacity during operation. This invention relates to a structure in which a part of the auxiliary grain tank is made of auxiliary cloth.

(B) Prior art Conventionally, combine harvesters with auxiliary grain tanks made of elastic plates or auxiliary cloth have been known since the U.S. Pat.
Something like No. 40 is known to the public.

However, since the conventional auxiliary grain tank made of auxiliary cloth did not take into account the relationship with the spout of the grain lifting cylinder, the capacity was significantly increased (the auxiliary grain tank was not filled with auxiliary grains), and the auxiliary grain tank made of auxiliary cloth There was a problem in which the auxiliary cloth part was torn in an instant due to direct contact with the paddy thrown out of the grain hoist for a long time due to the paddy containing a lot of silicon bones.

(c) Problems to be Solved by the Invention The main purpose of the present invention is to eliminate these conventional problems, and to solve the problem by connecting the input port of the grain lifting cylinder of the combine harvester and the extension line in the discharge direction to the auxiliary grain tank. The auxiliary grain tank is placed below the cloth to ensure that the paddy is filled even in the area where the capacity has increased.

(d) Means for Solving the Problems The objects of the present invention are as described above, and the structure of the present invention will now be explained.

In a combine harvester grain tank, an auxiliary grain tank 1 that can be freely opened and closed left and right around a pivot point is tightly and tightly fixed to the grain tank with an auxiliary cloth 2, in which the grain tank and the auxiliary cloth The upper end fastening part is provided above the extension line in the discharge direction of the grain dumping port.

(E) Embodiments and Functions The objects and structure of the present invention are as described above. Next, the structure and functions of the embodiments shown in the attached drawings will be explained.

The overall outline will be explained with reference to FIGS. 1, 2, and 3.

A lower auger 15 of a conveying auger 13 is arranged at the rear of a seat 17 of the combine harvester. The paddy in the grain tank 6 is collected by a screw conveyor 8 and sent to the lower end of the lower auger 15. After the grains are fried halfway by the lower auger 15, the grains are transferred to the transport auger 13 and directly transported to a trunk on a ridge or a loading platform of an accounting carrier. The conveyance auger 13 is the lower auger 15
It is constructed so that the horizontal and vertical angles can be changed. The paddy from the first mouth is carried into the grain tank 6 from the threshing device 14 via the grain lifting cylinder 7. 1
Reference numeral 6 denotes an engine room, in which the engine that serves as the driving force for the entire combine is placed.

The structure and operation of the auxiliary grain tank 1 will be explained with reference to FIGS. 2, 3, and 4.

When transporting a combine harvester from field to field, the auxiliary grain tank 1 must be stored and the combine must be driven with a smaller width, as this is regulated by laws such as the Road Traffic Act and the Road Transport Vehicle Act. It has to be.

On the other hand, when working in the field, there are no restrictions under these laws, so as shown in Figure 2, the auxiliary grain tank 1 can be extended to the side to increase the storage capacity. It is desirable to do so.

The auxiliary grain tank device of the present invention includes an auxiliary grain tank 1 made of iron plate and an auxiliary cloth 2.

Conventionally, it is known that the auxiliary cloth 2 is also made of iron plate and is inserted and stored inside, but in this case, it is impossible to completely seal the sliding part between the grain tank and the auxiliary grain tank. It was. In the present invention, the grain tank 6 and the auxiliary grain tank 1 are connected by the auxiliary cloth 2,
The two are completely sealed, and the auxiliary cloth 2 also serves as an expansion tank.

In addition, it is cheaper in terms of weight and cost to use auxiliary cloth for the tank rather than constructing the entire auxiliary grain tank using iron plates. Engagement holes 12a, 12b, 12c, 12d, etc. are provided on the side surface of the auxiliary grain tank 1, and engagement pins 9 are provided on the corresponding grain tank 6 side. As shown in FIG. 6, the engagement pin 9 slides within the guide 11 and is prevented from being removed after being inserted into the engagement hole 12 by the lock pin 10. In addition, as shown in Fig. 4, the auxiliary grain tank 1 has a non-triangular fixation pattern;
The upper end of the triangle is made into a notch at part 1a, and the wasteful part where the paddy thrown in from the grain frying conveyor 7 is not accommodated is cut off to match the extension line of the auxiliary cloth 2. Further, a guide rod 4 is provided across the surface of the notch 1a and the upper part of the vertical surface 1b.

Guide rod 4 connects auxiliary grain tank 1 to grain tank 6
This is provided to prevent the auxiliary cloth 2 from turning over when stored inside the container and coming into contact with the auxiliary grain tank 1 and scratching or damaging the paint. On the contrary, it also has the effect of preventing the corners of the auxiliary grain tank 1 from damaging and tearing the auxiliary cloth 2. 5 is a handle. The engagement hole 12 is when the auxiliary grain tank 1 is fully pushed in in 12a, and when only half is pushed in in 12b.
12c is a case where only the auxiliary cloth 2 is stored.

As shown in Figure 5, a reinforcing chain 3 is interposed between the grain tank 6 and the auxiliary grain tank, so that it can withstand the weight of the capacity of this part when the auxiliary grain tank is extended to its maximum extent. We are reinforcing it because there will be cases where it is not available.

Since this reinforcing chain is interposed on the front and rear inner walls of the grain tank 6 and the auxiliary grain tank 1, the auxiliary cloth 2 does not bulge inward to a large extent even when folded. 20 is a pivot point of the auxiliary grain tank 1.

A conventional grain tank device is disclosed in FIGS. 7 and 8.

That is, the grain tank 6 and the upper end fastening portion 6a of the auxiliary cloth 2 were present below the extension line P in the discharge direction from the spout of the grain lifting cylinder 7. Therefore, as shown in Figures 7 and 8, the paddy discharged from the grain lifting cylinder 7 first collides with the inner wall of the six grain tanks, where it loses its inertia during discharge and falls downward. As a result, the auxiliary grain tank 1, which is open, is not staked out.

In addition, as the rice thrown away from the throwing spout constantly collides with the fastening parts of the auxiliary cloth, the auxiliary cloth 2 is rubbed and torn by the chaff containing a large amount of silicon. In order to eliminate this problem, in the present invention, as shown in FIGS. 9 and 10, the grain tank and the upper end fastening part of the auxiliary cloth are provided above the extension line in the discharge direction from the spout of the grain lifting cylinder 7. It is. By doing this, the discharge direction extension line P and the direction of the auxiliary cloth 2 are parallel to each other, and the thrown out paddy no longer hits the auxiliary cloth 2 directly.

In addition, the auxiliary grain tank 1 of the protruding auxiliary cloth was also filled with paddy thrown out by the force of the grain lifting cylinder, and the auxiliary grain tank could be used effectively.

In the embodiment shown in FIG. 10, a collision plate 19 is provided at the upper end connection portion of the grain tank 6 and the auxiliary cloth 2, and the paddy is concentratedly applied to this plate. Since this collision plate 19 is pushed up toward the auxiliary grain tank 1 by the force of the paddy, the effect of sufficiently accumulating paddy in the auxiliary grain tank is not lost. Furthermore, when the auxiliary grain tank 1 is stored, it is rotated inward so that it does not get in the way of storage. It is also effective to configure the grain-lifting cylinder so that the opening is angled downward, as shown in FIGS. 9 and 10.

(f) Effects of the Invention Since the present invention is constructed as described above, the auxiliary grain tank is filled with paddy from the spout of the grain lifting tube 7, so the auxiliary grain tank can be used effectively. Since the rice grains do not directly collide with the auxiliary cloth, there is less fear that the auxiliary cloth will be torn by the rice containing a large amount of silicon.
