Description

[Detailed Description of the Invention] The present invention relates to a grain bagging device in which a shutter for opening and closing the grain discharging tube that discharges grains into a replaceable collection bag is provided. The aim is to automate the process and make the bagging process easier.

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

The example diagram shows a grain bagging processing device mounted on a combine harvester, in which grains processed by a threshing device 1 are lifted and conveyed by a grain lifting cylinder 2 and sent into a grain storage hopper 3. After that, it is stored in a replaceable collection bag 4.

That is, a collection bag 4 is placed at the bottom of the hopper 3.
... A pair of front and rear grain discharge cylinders 5, 5 for discharging grains are provided, and these discharge cylinders 5,
Each of the shutters 5 is equipped with a sliding shutter 6, 6 for opening and closing the shutter. Further, a sensor 7 for detecting fullness of grains is provided in a portion of the discharge tubes 5, 5 lower in the grain discharge direction than the shutters 6, 6.
7 is provided, and based on the detection results of the sensors 7, 7, the shutters 6, 6 are automatically and reversibly changed from the open state to the closed state in conjunction with switching from the non-full detection state to the full detection state. Electric motors 8, 8, which are capable of forward and reverse rotation, are provided as drive mechanisms for switching between the two directions. This electric motor 8
The pinion 9 fixed to the output shaft 8a is engaged with the rack 10 attached to the shutter 6, and the forward or reverse rotation drive circuit 11a or 11b is activated based on the signal from the sensor switch 7a of the full detection sensor 7. It is configured to be activated and rotated, and its rotation is automatically stopped based on a signal from the limiter switch 12a or 12b pressed by the shutter 6 in the closed state or the shutter 6 in the open state. There is.

In the figure, reference numeral 18 is a cantilevered bag support rod that removably inserts and supports the collection bag 4 in a suspended state, and a spare bag 4a is supported at the base of the rod. There is. Reference numeral 17 in the figure is a bag presence/absence detection sensor that detects whether or not the collection bag 4 is attached depending on whether or not the light from the light emitter 17a is received by the light receiver 17b. Based on this, the shutter 6 when the bag 4 is not attached
The device is designed to check and prevent opening operations. Further, the main switch 13 is a manual switch for manually opening and closing the shutter 6, and the reference numeral 15 is a changeover switch for switching between a state in which the shutter 6 is automatically opened and closed and a state in which it is manually opened and closed. It is.

Reference numeral 16 is a timer circuit for causing the shutter 6 to open after an appropriate time delay when switching from the closed state to the open state, and is set to a time commensurate with the bag changing operation time.

According to the above configuration, the grains fed into the hopper 3 are stored in the collection bags 4, 4 through the discharge cylinders 5, 5 in sequence, and the grains are stored in the collection bags 4, 4,
When the hopper 4 is full of grains, the shutters 6, 6 are automatically closed, and then the hopper 3 is closed.
The grains will be stored inside. Therefore, each time the hopper 3 is full of grains, the operator must
Bag filling work is performed while changing bags by removing a full bag and equipping a new bag at the same time, but the bag filling work can be performed without requiring any special operation on the shutter 6. It became.

In addition, according to the present invention, not only can the operation of the shutter 6 be omitted, but there are also the following advantages. In other words, the grains stored in the collection bag 4 are
When the grains are crushed by vibrations of the machine, the shutter 6 automatically opens and more grains are fed into the bag 4. It will be. Therefore, it is convenient to store a desired amount of grains in the bag 4 without shortage.

Note that if more grains are fed into the bag 4 in this way, there is a risk of overfilling the bag with grains.
In order to prevent this, for example, a device that detects the bag support load of the bag support rod 12 is provided, and the number of openings of the shutter 6 when the support load detection device detects a load above a certain value is set to a set number of times. It is even better to incorporate a mechanism to suppress this.

As clarified in the above embodiments, the present invention provides a grain bagging processing apparatus in which a shutter for opening and closing the passage is provided in the discharge cylinder at the lower end of the storage hopper, and a drive mechanism for opening and closing the shutter; a fullness detection sensor that controls the drive mechanism to close the shutter based on detection of fullness of a grain collection bag attached to the discharge tube, and to control the drive mechanism to open the shutter in a non-detecting state; The shutter is equipped with a sensor for detecting the presence or absence of a bag, which detects that the shutter is not attached to the bag and checks the control to the opening side, and a timer circuit which delays the opening control of the shutter by the drive mechanism for a predetermined period of time. This configuration produces the following effects.

That is, with the configuration of the present invention, the shutter is automatically closed based on the fullness detection by the fullness detection sensor, and the shutter is automatically opened after an appropriate time when the bag is assumed to have been replaced. The discharge is restarted. Moreover, if the bag exchange has not yet been completed, the shutter is pulled open by the action of the presence/absence detection sensor, and grains are completely prevented from flowing out.

Therefore, according to the present invention, it is possible to carry out a good bag filling operation without requiring any manual operation of the shutter.
