Description

[Detailed description of the invention] The present invention provides a hopper in which four or more grain storage parts are arranged in parallel in the front and back and in and out directions on the lateral side of the threshing device main body, and the grain storage parts are arranged in parallel in the inside and outside directions. The inner grain storage section is located between the side wall of the threshing device main body and the outer grain storage section, and the outer grain storage section is suspended and supported in a position where the outer side of the machine body is open. The grain storage bag is located above the grain storing bag, and the grain lifting device is disposed on the threshing device main body side of the hopper in a state in which the threshed grain is discharged and supplied toward the center between the outer grain storage sections. This invention relates to a grain recovery device for a threshing machine with a discharge port facing the grain.

In this type of grain recovery device, as described above, the grain lifting device is configured to discharge and supply the threshed grain from the threshing device main body side of the hopper toward the center between the outer grain storage parts. , when full,
Grain can be stored in an inclined state where the grain becomes bulkier toward the outside. In other words, since the actual grain storage capacity of the outer grain storage section can be made larger than that of the inner grain storage section, it is possible to fill the outer grain storage bag with a predetermined amount of grain during bagging operations. This has the advantage of being able to pack bags in a highly workable state, such as by taking out full bags one after the other starting from the outside.

However, in the conventional device, the grains discharged from the grain lifting device are supplied as they are to the outer grain storage section, and then the grains in the outer grain storage section are supplied as an overflow to the inner grain storage section. The outer grain storage bag largely protrudes toward the threshing device main body as the grain is collected, and as a result, the storage space is limited by the side wall of the threshing device main body and the outer grain storage bag. The overhanging space of the storage bag was narrow, and the amount of grain packed inside the bag was insufficient.

In view of the above-mentioned circumstances, the purpose of the present invention is to increase the actual grain storage capacity of the outer grain storage part while making it possible to equalize the amount of packed inside and outside bags. The characteristic structure of the grain recovery device of the threshing machine according to the present invention, which was made to achieve this purpose, is that the grain discharged from the grain lifting device is received in the hopper, and the grain is distributed to the inner grain storage portion and guided to flow down. The present invention is characterized in that a gutter-like member is provided, and when a predetermined amount of grain is stored in the inner grain storage part, the grain can be supplied to the outer grain storage part.

The functions and effects of the above characteristic configuration are as follows.

That is, at the start of grain collection into the hopper, the grain discharged from the grain lifting device is preferentially guided down to the inner grain storage section via the gutter-like member, and a predetermined amount of grain is stored in the inner grain storage section. When the hopper is full, the grain is fed to the outer grain storage section, so that when the hopper is full, the grain is stored in an inclined state that is higher toward the outer grain storage section, reducing the actual grain storage capacity of the outer grain storage section. Even when expanding, the outward protrusion of the inner grain storage bag due to grain collection is not obstructed by the outer grain storage bag, allowing a predetermined amount of grain to be stored in each of the inner and outer grain storage bags. Can be filled. In addition, since the outer side of the outer grain storage section is open to the outside of the aircraft, the outer grain storage bag is allowed to extend outward.
Therefore, even if the inner grain storage bag protrudes outward, the amount of grain stored in the outer grain storage bag will not be limited.

Therefore, by making a simple structural improvement by simply providing a gutter-like member within the hopper, it has become possible to achieve the above-mentioned advantages while also equalizing the amount of inner and outer bag filling.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The first part of the combine harvester's grain collection device is
As shown in FIGS. 4 to 4, six grain storage sections 2A, 2B, . A certain hopper 2 is installed, and the ceiling wall portion 3a of the ceiling wall 3 of this hopper 2, which corresponds to the entire front grain storage parts 2A, 2B and the front part of the central grain storage parts 2C, 2D, is moved from the upper part of the outside to the inside. The threshing device body 1 side of the sloping ceiling portion 3a is configured to have a downwardly inclined attitude, and the threshed grain is placed in a central portion between the outer grain storage portion 2B and the central outer grain storage portion 2D. The discharge port 4a of the grain frying device 4 is faced in a state where the grains are discharged and supplied. Note that the grain storage portions 2 are arranged in parallel in the inner and outer directions.
Among A, 2B...inner grain storage parts 2A, 2C, 2
E is located between the side wall of the threshing device main body 1 and the outer grain storage parts 2B, 2D, 2F, and the outer grain storage parts 2B, 2D, 2
F is located above the grain storage bag 16 which is suspended and supported in a position where the outer side of the machine body is open.

Among the grain storage portions 2A, the front portions of the front inner grain storage portion 2A and the center inner grain storage portion 2C are configured to be slightly narrower than the other portions, and the sloped ceiling of the ceiling wall 3 is configured to be slightly narrower than the other portions. Another ceiling wall portion 3b connected to the portion 3a is configured in a horizontal position, and is located above the outer grain storage portions 2B, 2D, and 2F across the front side wall 5 and the rear side wall 6 that constitute the hopper 2. A screw 7 for leveling the stored grain is installed.

The grains are stored between the front inner grain storage section 2A and the front outer grain storage section 2B and between the front grain storage sections 2A, 2B and the central grain storage sections 2C, 2D. 2B is provided with first and second grain flow guide plates 8A and 8B that can guide the grain flow down, and between the two central grain storage parts 2C and 2D,
A third grain flow guide plate 8C capable of guiding grains downward to the central outer grain storage section 2D is provided, and the central inner grain storage section 2C and the rear inner grain storage section 2
A fourth grain flow guide plate 8D is provided between the grain flow guide plate 8C and the third grain flow guide plate 8C, which can guide the grains downward toward the rear inner grain storage portion 2E.

Further, between the central grain storage parts 2C, 2D and the rear grain storage parts 2E, 2F, there is provided a fifth grain flow guide plate 8E that can guide the grain downward toward the central grain storage parts 2C, 2D. , are provided to form a V-shape with the fourth grain flow guide plate 8D in side view, and both the rear grain storage parts 2E,
Between 2F, its upper end is the fifth grain flow guide plate 8E.
A partition plate 9 is provided in a substantially vertical position and located at the same level as the upper end of the partition plate 9.

Therefore, between the first grain flow guide plate 8A and the second grain flow guide plate 8B, the lower end thereof is on the ridge line between the front grain storage parts 2A, 2B and the central grain storage parts 2C, 2D. A V-shaped notch 10 is formed in a side view located at the grain frying device 4.
receives the grain discharged from the V-shaped notch 10 and the two grain flow guide plates 8A, 8B.
Inner grain storage parts 2A, 2C through the back side space of
A V-shaped gutter-like member 11 is provided for guiding the flow down in a distributed state, and the inner grain storage portion 2A,
When a predetermined amount of grain is stored in 2C, the V
Grain can be supplied to the outer grain storage parts 2B and 2D through the letter-shaped notch 10 and the upper part of the lower end of the gutter-like member 11.

Further, on the fifth grain flow guide plate 8E, the center outer grain storage section 2 is placed before the rear outer grain storage section 2F.
A through hole 12 is formed through which the grains in D are supplied to the rear inner grain storage section 2E by overflow.

When storing threshed grains in the hopper 2, the grains are stored in approximately the following order.

That is, front inner grain storage section 2A, center inner grain storage section 2C→front outer grain storage section 2B, center outer grain storage section 2D→rear inner grain storage section 2E→
This is the order from the rear outer grain storage section 2F.

Cloth boots 14 are attached to the grain discharge tubes 13 of each of the grain storage sections 2A, and these boots 14 are installed.
A chuck 15 in a vertical position that can be opened and closed from its lower edge is attached to the chuck 15.

When the grain storage bag 16 is removed, when the chuck 15 is opened, the grains in the boot 14 smoothly enter the bag 16, making it easy to remove the bag 16.

Incidentally, instead of providing the chuck 15 on the boot 14, the boot 14 is wound into a cylindrical shape with both sides of the boot 14 overlapping each other in the longitudinal direction, and
It is also possible to fasten only the upper part of the overlapping side.

Further, in the above-described embodiment, the cross-sectional shape of the gutter-like member 11 is V-shaped, but it may be formed into a U-shape, a semicircle, a U-shape, or the like.

Furthermore, the gutter-like member 11 may be configured to be detachable. With this configuration, if you have a very small field or want grain in advance by 2 or 3 bags, by removing the gutter-like member 11, you can preferentially store grain from the outer grain storage section 2B side. Therefore, the grain can be stored in the outer grain storage section 2A.
The work of removing a full bag can be performed more easily than when preferentially storing from the side. However, in normal cases, the gutter-like member 11 is attached to preferentially store grains from the inner grain storage section 2A side, thereby making the amount of bagging uniform.

Moreover, instead of configuring the gutter-like member 11 to be detachable, as shown in FIG.
The gutter-shaped member 11 may be configured to be able to swing freely between an active position in which it opens upward and a non-operative position in which it opens downward.Furthermore, the attitude of the gutter-like member 11 can be changed by an operation provided in the control section or the like. It may be configured and implemented to be performed by Nova.
