Description

[Detailed description of the invention] The present invention is a grain bagging and recovery device mainly applied to a combine harvester, in which a bag is provided with a shutter and a bag fullness detection sensor at the bottom of a plurality of hopper chambers to which grains are supplied. A discharge port for clogging is provided, and the automatic closing drive device of each shutter is activated based on the detection of fullness at each discharge port, and the automatic closing drive device of each shutter is activated by detecting that each shutter is closed. This relates to the provision of a sensor that cuts off power to the device.

For example, in a conventional combine harvester, grain bagging and recovery equipment detects and displays this when all hopper chambers are full of grain, and then interrupts the operation and removes the full bags. Workers were informed of when to replace empty bags, but in this case, the time when all hopper rooms were filled with grains differed depending on the amount of grains attached to each planted culm. Because of the irregularity of the bags due to certain reasons, it has been difficult to adopt a work style in which all the bag replacement work is carried out at a location with good working conditions, such as at the edge of the field.

In view of this, the present invention focuses on the fact that each hopper chamber is filled with grains by continuing grain supply even after each bag is filled with grains and the shutter of the discharge port is closed. By making effective use of a sensor that prevents unnecessary energization of the shunter automatic closing drive device after the shunter is closed, bag replacement work can be performed in locations with long working conditions with a simple structure. The purpose is to notify customers when it is time to replace the bags.

The grain bagging and collecting device according to the present invention, as described at the beginning, is characterized in that the display device is configured to be energized when all the sensors perform detection operations. .

That is, according to the present invention, when the sensor is used as a switch of the display device, it is notified that all the bags are full of grains, and, for example, when a button is pressed on a combine harvester at the center of the field,
Even if the display device is energized, it will take a considerable amount of time to fill all the bags and fill all the hopper rooms with grain, so after the notification, the combine harvester must be turned on while continuing the intended work. It is possible to move the bag to a place with good working conditions at the edge of the field and replace the bag at this place with good working conditions.

Therefore, the present invention has a simple structure, can appropriately notify the time for bag replacement, and is thus particularly useful as a bagging and collecting device for grains in a combine harvester.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on a grain bagging and collecting device for a combine harvester shown in the drawings.

First, there is a grain hopper disposed on the side of the on-board threshing device 8, which has a plurality of hopper chambers 1A, through which grains from the grain frying screw conveyor 9 are sequentially supplied to the overflow set. have

4... is a grain outlet for bagging installed at the bottom of each hopper room, and these are connected to the slide-type opening/closing shirt car 2... and the grain loaded therein. When the grain collection bag 10 is full of grains, the discharge port 4
It is designed to turn on when it comes into contact with the grains stored inside.
It has a bag full detection sensor 3 using a normally open switch to detect this.

Each of the shutters 2... is closed by a spring 5A and opened by manual operation, and is capable of engaging and disengaging from the spring 5A. The locking tool 11... is machined to automatically maintain its open state, and the locking tool 11... is forcibly brought into the disengaged position by the energized solenoid 5B. It can be switched.

Further, 6... is a shutter closing movement detection sensor using a normally closed switch that detects when the shutter 2 closes by coming into contact with the shutter 2... and switching to OFF'. .

FIG. 5 shows an electric circuit, in which the solenoid 5B... is connected in series with both sensors 3..., 6..., and based on the fullness detection by the bag full detection sensor 3... energizes the solenoid 5B to close the shutter 2, and as the shutter 2 closes, the solenoid 5B is activated based on the detection by the shunter closing movement detection sensor 6. The structure is such that the electricity is cut off.

In other words, the automatic closing drive mechanism 5 for the shutter 2...
For example, it is composed of a spring 5A... and a solenoid 5B.

12 is a power supply for the circuit, 13... is a switch for manually closing the shutter connected in parallel with the bag full detection sensor 3..., 14 is a main switch, and 15 is a fuse.

Further, 16 is a buzzer, which is used for the hopper 1.
When the container is full of grains, it comes into contact with the grains and turns on, and the sensor 17, which uses a normally open switch, detects this and energizes.

In this embodiment, a lamp 7, which is an example of a display device that is activated by electricity, is provided, and when any one of the shutter closing movement detection sensors 6 is in an ON state, this sensor is turned on. By being grounded through 6..., a switch circuit 18 is activated that energizes the lamp 7 when the lamp 7 is de-energized and all the sensors 6... are switched to the OFF state. Set it up, have it,
All the shutters 2... are configured to close to indicate that all the bags 10 are fully filled with grains.

The switch circuit 18 includes a transistor Tr, various resistors R1, R2yR3, and a rectifier D.

The bag 10 is held in the grain storage position by a pair of hanging support rods 19, 19 and a stand 20.
