Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressurized combine grain recovery device for collecting threshed grain in bags.

Generally, in the above-mentioned collecting device, a hopper for bagging grains is installed on the side of the threshing device, and an auxiliary worker is involved to bag the grains while transferring the grains to the machine in 11 shifts. - Hitoriyuki ↓ It is now possible to do the work by one person, connecting until the seven barrels are full, and then packing the stored grains into bags and taking them out. Since a large amount of grain cannot be stored at the same time, the harvesting operation must be interrupted within a short period of time to bag and discharge the grain, which has the drawback of not increasing work efficiency.

In other words, the grain bagging hopper is installed at a relatively high position to provide space for bagging below, so its capacity is smaller compared to grain tanks developed specifically for large-scale operations. , it was not possible to operate continuously for a long time.
Also, if the hopper is made higher to increase the capacity of the hopper, the center of gravity of the aircraft becomes higher, which impairs stability.
Due to the increased weight of part of the hopper on the negative side of the aircraft, the left-right balance was likely to be lost.

Particularly in wet fields where large-scale work is carried out because grain bags cannot be left unattended, the large hopper can cause the machine to lose its balance.
This had a negative impact on the harvesting process itself, making it difficult to increase the size of the hopper.

The present invention has been made focusing on the above points,
'The objective is to provide a grain collecting device that allows one person to work continuously for long periods of time by rationally increasing the size of the hopper, and also suppressing the deterioration of the balance of the machine due to the increased size of the hopper. shall be.

A feature of the present invention is that a hopper for storing grains from the first grain hoisting device is placed on the upper part of the threshing device in which a feed chain is stretched along the side of the machine, opposite to the side where the feed chain is present. The hopper is installed so as to overhang from the threshing device, and the overhanging part of the hopper is provided with a bagging outlet, and at the bottom of the hopper, a conveyor for transferring the grains to the outlet side is installed horizontally. , its effects are as follows.

In other words, by installing the hopper over the membrane removing device while leaving space for bagging on the side of the threshing device, it is possible to increase the size of the hopper without raising the center of gravity or losing the left-right balance. As a result, even when working alone in a wet field, the harvesting work can be carried out continuously over a long period of time without changing the posture of the machine, making it possible to improve work efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figure 1, a pre-processing device (2) is installed at the front of the machine, which lifts and reaps the planted grain culms and transports them to the threshing device (1). Side of the aircraft
A threshing device t1),;,j with a feed chain (3) stretched along the side, and shredding the threshed waste straw husks conveyed by the feed chain (3) to the rear side of this threshing device il+. The waste to be processed (6) is arranged to constitute a combine harvester.

Figure 2, and 1. As shown in FIG. 8, the grain storage hopper (6) is installed on the side opposite to the side where the feed chain (3) is present, projecting from the threshing device (1), and a bagging discharge is installed in the projecting part. An outlet (6A) is provided, and a horizontal screw conveyor (7) for transferring the grains to the discharge port (6A) is installed horizontally at the bottom to constitute a grain recovery device.

In addition, a first grain frying device (
5) enters the vertical screw conveyor (5) from below, and at the tip of the vertical screw conveyor (5) there is an opening (5) formed in the outer case (5A) through which the lifted grains are stored.
A rotary blade (5a) is provided to uniformly disperse and supply the liquid from 5b) to the entire inside of the hopper. 10th Hopper (6)
A through hole (13) that allows upward swinging of the hopper (6) is provided at a location corresponding to the first lifting and killing device (5), and below this hole (I3) is a through hole (113). A cover member 04) capable of closing the grain frying device (6) is fixed to the outer cylindrical case (5A)K of the grain frying device (6).

Further, the discharge port (6A) of the hopper (6) is provided with a sliding shutter (6a) and a movable discharge cylinder that can move up and down.
(6b) is provided below the discharge port (6A), and a bag support rod t81 is inserted into (8) to sequentially send out the loaded grain storage bags (9) directly below the discharge tube (6b). An automatic bagging mechanism θ is provided to perform the grain filling process.

The horizontal screw conveyor (7) is equipped with a drive motor (1
0), and the City 18 Sea X'Tsuku (6a
A detector (11) is provided to detect the opening and closing of the drive motor (lol), and a detection signal from the detector (11) is output to a control device that controls starting and stopping of the drive motor (lol), thereby causing the shutter (6a) to open. The motor (1
0).

Note that the detector (11) may include a limit switch,
Proximity switches etc. can be used.

As shown in FIG. 4, the hopper (6) has a discharge port (6
If A) is held in two shares, the horizontal screw conveyors i7) and (7) are provided for each, and @
A configuration may be adopted in which the first grain frying device (5) is located at an intermediate position between the recording discharge ports (6A) and (6A).

It should be noted that the hopper (6) is aligned with the horizontal axis (
X), and the upper surface cover 05) of the handling chamber (A) in the thresher tl) is pivotally supported around the same horizontal axis (X) so as to be swingable up and down. ing.
