Abstract

PURPOSE:To enable to carry grain stalks in the direction along the bodies of the stalks whose ear tips are directed forward, by disposing projections narrower than the lateral width of a feed conveyor in a zigzag state along the carrying direction and carrying the grain stalks toward a stalk-discharging opening side between guide plates and the conveyor. CONSTITUTION:Grain stalks collected with an auger on the side of a feed conveyor 5 are carried with projections 5d and carrying bodies 5c rotation-driven with a chain 5a on the side of a grain stalk-discharging opening 11 while passing through between guide plates 10 disposed on the lower side of the feed conveyer 5 and the conveyer 5. When the grain stalks are collected from the lower side of the augur 4 into the conveyer 5, the grain stalks directed laterally or obliquely are carried along the stalk-carrying direction of the conveyer 5 while the ear tips of the grain stalks are directed toward the side of a grain stalk- discharging opening, thereby raising the probability for directly beating the ear tips with a threshing cylinder, accelerate the acquisition of single grain granules and improve the efficiency of threshing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a whole-culm input type combine harvester, in particular to a conveying structure for conveying harvested grain culms to a threshing device.

[Conventional technology]

As a whole culm input type combine harvester, for example, the 1986-11
As disclosed in Japanese Patent No. 2435, grain culms that have been harvested and gathered in the center by an auger are sent to a threshing device by a feed conveyor, and this feed conveyor has a pair of left and right It has a structure in which a horizontally long plate-shaped conveyor is attached to the chain, and the grain culm is pushed up toward the threshing device by this conveyor.

[Problem to be solved by the invention]

In the disclosed structure, the threshing device is equipped with a rotationally driven handling cylinder and a fixed receiving blade, and in order to thresh the grain culm between the handling cylinder and the receiving blade, the threshing process is carried out from the feed conveyor. There are no particular restrictions on the orientation of the grain culms fed into the device.

However, in recent years, whole-culm loading type combine harvesters for soybeans and buckwheat have appeared, and in this type, when the grain culm is fed into the threshing device by the feed conveyor, the handling barrel is placed against the grain culm. The method is to thresh by applying a direct blow from the bottom to the top (Jikko 63-27
(See Publication No. 554).

Therefore, in the model for soybean and buckwheat, it is preferable from the viewpoint of threshing efficiency to transport the harvested grain culm vertically along the culm direction with the ear tip at the front and feed it into the threshing device. In the structure of the feed conveyor as disclosed in Japanese Unexamined Japanese Patent Publication No. 63-112435, grain culms facing sideways are fed sideways, while grain culms facing horizontally are not transported vertically with the ears in front. The situation is difficult to overcome.

Here, the present invention has been made with attention to the above-mentioned problem, and is configured so that the grain culm can be conveyed in the vertical direction along the culm direction with the ear tip at the front as much as possible and fed into the threshing device. It is an object.

[Means to solve the problem]

The feature of the present invention is that in the above-mentioned full culm input type combine harvester, the protrusion is narrower than the left and right width of the feed conveyor in a posture along the width direction of the feed conveyor, and also along the conveyance direction of the feed conveyor. The grain culms are conveyed to the grain culm discharge port side between the guide plate disposed below the feed conveyor and the feed conveyor by the protrusions arranged in a staggered manner and rotationally driven. The functions and effects are as follows.

[For production]

With the configuration described above, if the tip of the grain culm gets caught on the protrusion (5d) of the feed conveyor (5), as shown in FIGS. However, as the protrusion (5d) moves (to the right or above in the paper), the grain culm changes to a vertical posture (in the horizontal direction in the paper) with the tip in front (to the right or above in the paper).

This means that the width of one protrusion (5d) is the feed conveyor (
Since it is narrower than the left and right width of 5) and is arranged in a staggered manner, a relatively wide space is obtained around one protrusion (5d). Due to the pushing action and the action of the root side of the grain culm sliding against the guide plate on the lower side of the feed conveyor, the attitude of the grain culm changes from the tip to the tip when the grain culm is scraped under the feed conveyor and during conveyance. This makes it easier to change from the front to the vertical orientation.

〔Effect of the invention〕

As described above, it has become possible to feed the harvested grain culms into the threshing device using the feed conveyor in a vertical orientation with the ears facing forward as much as possible. As a result, when the handling drum of the threshing device hits the grain culm, there is a high probability that the handling drum will hit the tip of the grain directly, promoting the formation of single grains and improving threshing efficiency. did it.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings using a combine harvester for soybean and buckwheat, which is one of the large-scale all-culm thrower combine harvesters.

As shown in Fig. 3, a reaping section (1) is arranged at the front of the machine, and this reaping section (1) is equipped with a rotary scraping reel (
2), a clipper-type reaping device (3), an auger (4) that collects the harvested grain culms, a feed conveyor (5) that sends the grain culms upward, etc. A support part (8) is fixed to the front part of a vehicle body frame (7) equipped with a pair of left and right crawler traveling devices (6), and a support part (8) is attached around the horizontal axis (P, ) of this support part (8). The reaping section (1) is attached to be able to move vertically, and a hydraulic cylinder (

is structured as follows. In other words, as shown in Figure 1.2.3, a pair of chains (5a) are connected to the upper and lower drums (
5b), and a conveying body (5C) for conveying grain culms is installed across both chains (5a). This conveyor (5C) has a shape like a plate bent into a U-shape, and a protrusion (5d) narrower than the left and right width of the feed conveyor (5) extends along the width direction of the feed conveyor (5). They are provided on the carrier (5c) in a staggered manner and in a staggered posture.

With the above structure, the grain culms that have been gathered to the feed conveyor (5) side by the auger (4) are transferred to the chain (5a).
