Description

[Detailed description of the invention] The present invention forms a pair of funnel-shaped compartments with a bagging outlet at the bottom of a hopper that collects grains that are sprung out from the upper end of the grain lifting device and is discharged. The structure is configured to preferentially supply the spilled grains to the compartment side of the hopper, and a sensor is used to detect the fullness of the paddy bags loaded in each of the discharge ports to activate a preliminary warning device. A sensor is used to detect when grains have reached a set level or higher, and the main alarm device is activated.Furthermore, a partition plate is installed diagonally from the boundary ridge of the compartment above the other compartment that is not given priority supply. This invention relates to a grain collecting device for a combine harvester that is an overhang type.

As shown in FIG.
The inside of the hopper 7 is divided by the above-mentioned method, and the grain storage capacity of the compartment a to be supplied with priority is made larger than the other, so that, for example, at least one bag of grain can be stored in this large-capacity compartment. However, there were the following problems with the full warning operation.

When a combine harvester operator performs harvesting work using the recovery device configured as described above without a dedicated recovery attendant, the paddy bags 11,
When hopper 7 is full, sensors Sa and Sb sense it and a preliminary warning is issued by a warning lamp, etc., and the work continues, and sensor S senses that hopper 7 is full, and a main warning is issued by an alarm buzzer, etc. When the grains are dispensed, the operation is interrupted and the full bags are taken out and the grains in the hopper are packed in bags and taken out.As shown in FIG. Since the volume is small due to the overhang, the time required for paddy accumulation to reach the level detected by the sensor S after the paddy bag 11 below is full is short, that is, after the preliminary warning is issued. The time it takes for the main alarm to be issued is short, so there is little time to recognize that the hopper is about to become full due to the preliminary alarm and to make advance preparations for processing after the hopper is full; Having to interrupt the work in a hurry after knowing the main alarm that is issued, it is difficult to interrupt the work and think about the appropriate position to release the full bag during the period from the preliminary alarm to the main alarm. This made it difficult for unskilled people to handle it.

Therefore, with the present invention, even if there is a large difference in grain storage capacity on the pair of funnel-shaped parts due to the partition plate, the time from the preliminary warning that the paddy bag is full to the main warning that the hopper is full is relatively sufficient. This is an attempt to solve the above problem by making it possible to remove it.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows the overall plane of the combine harvester, in which a reaping preprocessing section 1 and a control section 2 are juxtaposed on the left and right, and the reaping preprocessing section 1
A threshing device 3 is mounted on the rear of the threshing device 3, and a grain collecting device 4 is disposed at the side of the threshing device 3 corresponding to the rear of the control section 2.

The grain collecting device 4 is configured to collect the grains splashed out from the upper end of the screw-equipped grain lifting device 5 of the threshing device 3 into a hopper 7 by means of a blade 6, and to pack the grains into bags at the lower part of the hopper 7 so that they can be taken out. The interior of the hopper 7 is divided into four sections in the longitudinal direction of the aircraft as well as in the longitudinal direction of the aircraft, and the bottom of each section a, at b, and b is configured in a funnel shape, Section a, b...
Bagging outlet 8a, 8a* 8bt 8 at the lower end of
b, and each discharge port 8a, 8b... is equipped with a manually operated shutter 9a, 9b.
A lob... is attached to each.

Further, below the hopper 7, two pairs of bag support rods 12a and 12b are installed in the front and rear, through which the rice bags 11 and 11 are inserted and supported.

The bag support rods 12a and 12b are respectively supported so as to be able to swing laterally, and are biased in the expanding direction by spiral springs 13 and 13, and their limits are regulated by stoppers 14 and 14.

At the biasing swing limit, both 12a and 12b are parallel to each other, and this interval is set to be smaller than the interval between the rod insertion holes at the upper end of the rice bag 11.

In addition, full-bag detection sensors Sa and Sb are attached to each of the discharge tubes 10a and 10b to detect the grain pressure and turn on the warning lamps La and Lb of the control unit 2, and the upper part of the hopper 7 is equipped with a sensor for detecting grains. A sensor S for detecting fullness of the hopper is installed, which senses the grain pressure and activates the warning buzzer island in the control section 2, and warning lamps La, Lb, etc. are installed as a preliminary warning device when each paddy bag 11 is full. After notifying the operator by lighting the hopper, it is configured to notify the operator that the hopper 7 is full by operating a warning buzzer as a main warning device.

Furthermore, a partition plate 15 extending above the inner compartment is extended from the boundary ridge between the inner and outer compartments a and b, and the grain storage capacity of the outer compartment a is set to be one bag or more. At the same time, a grain passage hole 16 in the form of a horizontally long slit is formed at the lower end of the partition plate 15.

[Next, the collection processing operation will be explained.

At the start of harvesting work, all discharge cylinders 10a and 10b are
The shutters 9a, 9b, etc. of... are manually opened and locked.

The grains that are sprung out and discharged from the grain lifting device 5 during the harvesting operation are preferentially supplied to the outer compartments a, a and the discharge port 8a.
From there, they are collected into the bag 11 below.

Then, when this reward ``1'' is full, this sensor Sa,
Detected at Sa, the preliminary warning lamps La and La are turned on, and subsequently supplied grains are deposited in this outer compartment a.

When the accumulation in the compartment a progresses a little, the supply begins to pass through the lower end hole 16 of the partition plate 15 to the inner compartment, and the filling of the lower bag 11 progresses from the open discharge port 8b, where When it is full, the preliminary warning lamps Lb, Lb are lit by the action of the sensors sb, sb, and the flow continues into the compartment through the hole 16.

When the grains in the inner compartment close the passage hole 16, the scattered grains are deposited in the outer compartment a, and then overflow into the inner compartment through the upper end of the partition plate 15.

Then, the overall grain level in the hopper increases,
When a predetermined height is reached, the sensor S detects this and activates the main warning buzzer, notifying the operator that the bag needs to be replaced.

Based on this warning, the operator stopped harvesting and then
First, the shutters 9a, 9b of all discharge cylinders 10a, 10b...
After closing..., take out the full bags 11, 11..., and then set the empty bags 11', which have been loaded in advance into the backs of the support rods 12a, 12b, under each discharge tube 10a, 10b... .

Then, the shutter 9a of the outer discharge tube 10a is opened to bag the accumulated grains in the section a.

When the bag is filled with an appropriate amount, the shutter 9a is closed and the full bag is removed.

Incidentally, since the grain passage holes 16 are formed at the lower end of the inclined partition plate 15, when the grains are taken out from the outer compartment, the natural flow from the inner compartment to the outer compartment a is blocked by the bridging phenomenon. .

Next, the shutter 9b of the inner discharge cylinder 10b is opened, and all the accumulated grains (not enough for one bag) in the inner compartment are packed into bags.

Then, shift the bag 11 which is less than full to the front and
0a, the outer shutter 9a is opened again and all the remaining grains in compartment a are packed into bags and taken out.

As explained above in the embodiments, according to the present invention, even the compartments whose capacity is reduced due to the extension of the inclined partition plate 15,
Since the grains in compartment a, which is to be supplied with priority, are allowed to flow in early through the passage hole 16 near the lower end of the partition plate 15, the fullness of the paddy bag 11 under the compartment which is not to be supplied with priority is detected and a preliminary warning is issued. After that, until the main alarm is issued, both compartments a,
A relatively long period of time is required for the deposition in step b, so that it is possible to make advance preparations for processing after the hopper is full with sufficient time after the pre-alarm is perceived.

Moreover, since the passage hole 16 is located near the lower end of the inclined partition plate 15 facing the small capacity compartment, when grains are taken out from the large capacity compartment a after the hopper is full, the flow from the compartment to the compartment a passes through the passage hole 16. Instead, the capacity of section a can be regulated as desired.
