Description

[Detailed description of the invention] The present invention provides a bagging outlet in a hopper that accommodates grains equivalent to or more than bags, and a shutter for opening and closing the outlet is biased to the closed state. A stopper is provided to keep the shutter in an open state when the shutter is opened by the stopper, and the locking action of the stopper can be canceled by energizing a solenoid connected to the stopper, and the shutter is activated based on the bag full detection. The present invention relates to a grain collecting device for a combine harvester, which constitutes a control mechanism for energizing the solenoid.

When a bag full of grains is taken out and the grains stored in the hopper are packed into a new bag, even after the bag is filled with grains, more grains remain in the hopper. of,
You may want to add additional filling to a full bag while applying vibration.
In such a case, in the collection device described above, the solenoid is energized at the same time as the bag is full, so the stopper does not work. The problem is that it is difficult to keep the shutter open with one hand and vibrate the full bag with the other hand, making it difficult to add residual grain to the bag. be.

One possible solution to this problem is to make it possible to stop the automatic locking release operation for the shutter by operating a switch, but there is a problem in that it requires time and effort to interrupt the operation.

In view of the above-mentioned circumstances, the present invention has been developed to make it possible to easily additionally bag the remaining grains in the hopper, and to eliminate the need for additional effort and to efficiently carry out the bagging work. The purpose is to

The present invention is characterized in that a grain collecting device for a combine harvester exposed to snow is provided with a control stop mechanism that cuts off the energization circuit to the solenoid based on a detection result that no harvesting work is being performed.

Therefore, by providing a control stop mechanism that cuts off the energization circuit to the solenoid, the shutter can be kept in the open state by the locking operation of the stopper even when no hand is placed, and the full bag can be easily vibrated with both hands. As a result, it has become possible to easily fill additional bags with the remaining grains other than the amount equivalent to one bag in the hopper.

Furthermore, when the reaping operation is stopped for bagging, the control stop mechanism is automatically activated, so there is no need to take any effort for this purpose, and the bagging operation can be carried out efficiently.

Next, an example of the present invention will be explained based on the drawings.

A frame body 2 that can freely swing up and down around a horizontal axis is extended forward from a machine body equipped with a crawler traveling device 1, and a culm lifting device 3, a culm reaping device 4, and a cut culm are transported to the rear of the machine body. Device 5
is provided on the frame 2 so that the cutting height can be adjusted by swinging the frame 2, and a threshing device 6, and a grain collecting device 7 for bagging the grains from the threshing device 6. is installed on the machine body, and a waste straw processing device 8 for shredding and discharging the threshed waste straw is provided at the rear of the threshing device 6. As the machine travels, it pulls up the shell culm, reaps it, threshes the reaped shell culm, and It consists of a combine harvester capable of bagging threshed grain and shredding threshed waste straw.

The grain collecting device 7 is configured by having a bagging outlet 9 at the bottom, a plurality of hoppers 10 that accommodate grains equal to or more than the amount of bags, and a threshing device 6 by a grain lifting device 11. The structure is such that the grains from the hopper 10 are supplied to the hopper 10 on the outside of the machine body and on the frontmost side, and the supplied grains are distributed to each hopper 10 by the action of the overflow and the leveling screw 12.

The structure is such that grain can be filled into the bag 22 or the filling can be stopped by opening and closing the sliding shutter 13 of each discharge port 9.

Both ridge outlets 9, 9, which are arranged in parallel in the left-right direction of the machine body, are shifted from each other in the front-rear direction of the machine body, so that the wall that forms the discharge port on the outside of the machine body does not interfere with the operation of the inner shutter 13.

In forming the opening 14 of the shutter 13, FIG.
As shown in Fig. 5, the opening peripheral line is inclined and the shutter 1 is
3. It is constructed to prevent grains from scattering during operation.

Further, the discharge port 9 may be made circular as shown in FIG. 5A, or the opening 14 of the shutter 13 may be shaped as shown in FIG. A similar effect can be obtained.

The shutter 13, which is biased in the closed state by the spring 15, is manually opened to open the stopper (swinging piece) 1 that is linked to the locking piece 16 of the shutter 13 and the solenoid 17.
When the shutter 8 is locked, the shutter 13 can be maintained in an open state.

The solenoid 11 is linked to the bag full detection sensor 19 provided at each outlet 9, and when the bag 22 is full, the solenoid 11 is energized to release the shutter 13 from being locked in the open state. A shutter control mechanism 20 is configured to automatically close the shutter.

Furthermore, the detection sensor 19 of the discharge port 9 for the bag 22 that will eventually become full, that is, the discharge port 9 on the final side inside the machine, is linked with the alarm buzzer BZ1,
A buzzer control mechanism 21 is configured to operate a buzzer Bz1 when the... is full.

Engine for the reaping device 4 and traveling device 1 (not shown)
Transmission of power from the mower is performed via a transmission transmission 23, and the reaping device 4 and traveling device 1 are configured to stop when the transmission 23 is set to neutral.

The control mechanism 20 of each solenoid 1γ... controls the open/close switch SW1, which is closed when the transmission 23 is set to neutral and detects that no reaping work is being performed.
and a control stop mechanism 24 which is incorporated into the control mechanism 21 of the alarm buzzer BZ1 and which automatically stops both control mechanisms 20 and 21 when it is detected that no reaping work is being performed. Even if the bag is full during bagging work, the locking piece 16 and the stopper (oscillating piece) 18 can be locked, and if the shutter 13 is kept open, the full bag 22 can be vibrated with both hands. The structure is such that the remaining grains in the hopper 10 can be additionally filled with the remaining grains.

Further, a fullness detection mechanism 25 is provided in the hopper 10 to which grains are finally supplied, that is, the rearmost hopper 10 inside the machine body, and this detection mechanism 25 and alarm buzzer Bz2 are linked to ensure that the entire loading 22. The buzzer Bz2 is configured to operate when all the hoppers 10 become full following the fullness of the hoppers 10.

The control circuit 26 for the buzzer BZ2 is constructed as shown in FIG.

The buzzer circuit 26 is configured to be opened and closed by operating the switch SW2 in the circuit 26.

Incidentally, the alarm buzzer BZ1 may be replaced with a bell or the like.
