Description

[Detailed description of the invention] The present invention is a device for tying waste straw carried out from a threshing device in a horizontal position, and a swinging switch between a posture for collecting bundles of tied waste straw released from this tying device and a discharging posture. A flexible dropper, a mechanism for electrically accumulating the number of binding operations of the binding device, and a mechanism for automatically and reversibly switching and swinging the dropper to a release position when the cumulative value of the accumulating mechanism reaches a set value. This invention relates to a waste straw processing device for a reaping/harvesting machine.

In reaping and harvesting machines such as combines, it is often necessary to turn off the main switch to interrupt the reaping and harvesting work. is cleared to zero, so when the main switch is turned on to resume work, the integration mechanism will start integration from zero with less than the set number of waste straw bundles remaining on the dropper. As a result, the number of collected and discharged straw bundles on the dropper becomes the sum of the set number and the number remaining on the dropper when work is resumed, which is a disadvantage that tends to cause problems such as clogging of the waste straw bundle, deformation and damage of the dropper, etc. It was hot.

An object of the present invention is to make it possible to rationally solve the above-mentioned problems when restarting work.

The characteristic configuration of the waste straw processing apparatus of the present invention, which has been made to achieve such an object, is that the automatic posture switching mechanism of the dropper automatically changes in conjunction with the operation of the main switch from on to off or from off to on. in that it is configured to operate;
The functions and effects of this feature configuration are as follows.

<Function> In other words, the dropper is automatically switched to the discharge position and swung in conjunction with the OFF operation of the main switch, which is an essential operation when work is interrupted, or the ON operation of the main switch, which is an essential operation when restarting work. Since the bundle of waste straw remaining on the dropper at that time can be discharged, when work is resumed, the integration can be started from zero with no bundle of waste straw remaining on the dropper.

<Effects> Therefore, when work is restarted, the number of bundles to be collected for the first time can be reliably set to the set value, which prevents clogging of the waste straw bundles, deformation and damage of the dropper due to the number of collected bundles exceeding the set number. This has made it possible to always perform the intended dropper work reliably and smoothly while avoiding such troubles.

Hereinafter, embodiments of the configuration of the present invention will be described based on the drawings.

In configuring the waste straw processing device of a combine harvester, which is an example of a reaping harvester, the straw is carried out from the threshing feed chain 2 to the straw removal mouth side of the threshing device 1 in a horizontal orientation perpendicular or almost perpendicular to the direction of movement of the machine. A first clamping and conveying device 3 that clamps the coming waste straw and conveys it diagonally toward the tip side at the rear of the machine.
and a disk-shaped cutter 4 and a binding device 5 whose position can be freely changed and fixed in the length direction of the waste straw culm, so that waste straw from the first clamping and conveying device 3 can be selectively supplied to the cutter 4 and the binding device 5. are doing. Also, a second clamping and conveying device 6 that clamps the bundled waste straw bundle released from the binding device 5 and conveys it diagonally toward the tip side at the rear of the machine; A plate-shaped posture correction member 7 that corrects the bundled waste straw bundle to a posture that is the same as or close to the above-mentioned sideways posture by coming into contact with the stock base of the bundled waste straw bundle, and collects the waste straw bundle after the posture correction A dropper 8 that can be freely switched between a position where the binding is performed and a release position; a mechanism 9 that electrically integrates the number of times the binding device 5 operates; and when the cumulative value of the integration mechanism 9 reaches a set value, the dropper 8 Mechanism 10 for automatically and reversibly switching and swinging the
has been set up.

To configure the attachment part of the dropper 8, an attachment frame 12 is extended rearward from near the tip side end of a frame 11 that supports the binding device 5 so as to be able to slide and change its position.
An arm 13 for supporting the dropper 8 is attached to the tip of the dropper 2 so that the dropper 8 can be switched and fixed between a working state in which the dropper 8 is in a substantially horizontal position and a retracted state in which it is in a substantially vertical position.

In configuring the integration mechanism 9, the bundling device 5
A through hole 5 is formed at a location corresponding to the end of the timing gear shaft 14 on the outer surface of the bundled transmission case 5A.
A sensor shaft 9A is attached to the periphery of the timing gear shaft 14, and the sensor shaft 9A is in constant contact with the de-cut portion of the sensor shaft 9A. A sensor case 9C including a switch 9B that detects and operates once when the gear shaft 14 rotates once is removably attached, and a counter 9 that adds up the number of detection operations of the switch 9B.
D is provided.

The automatic posture switching mechanism 10 of the dropper 8 is constructed as follows.

That is, the dropper 8 is rocked and biased to the collecting position between the locking member 15 using a bolt screwed and fixed to the arm 13 and the tongue piece 17 fixed to the swinging fulcrum shaft 16 of the dropper 8. A spring 18 is hung on the arm 13, and a first cam surface 1 of a cam 19 fixed to the swing fulcrum shaft 16 is attached to the arm 13.
A stopper 20 using a bolt that restricts the return position of the dropper 8 to the collection posture by the spring 18 by contact with the cam 19
A state in which the dropper 8 is locked in the collection posture by contacting the second cam surface 19b of the second cam surface 19b.
A locking member 22 with a roller 21 that can be freely switched between the unlocked state and the unlocked state that allows the dropper 8 to swing to the release position when released from the dropper 8; a torsion coil spring 23 that urges the locking member 22 to the locked state; Solenoid 2 capable of forcibly switching the locking member 22 to the unlocked state via the link 24
5 is set.

When the locking member 22 is switched to the unlocked state by the solenoid 25, the dropper 8 automatically switches to the discharging position and swings due to the weight of the collected and discarded straw bundle, and when discharging is completed, the spring 18 and By the cooperation of the locking member 22, the dropper 8 automatically returns to the collection position and is locked.

Further, a control section 27 is provided for outputting a control signal to the solenoid 25 to release the lock when the integrated value of the counter 9D reaches a set value of a setting device 26 that can change the number of collected waste straw bundles. There is.

By adjusting the setting device 26, the number of bundles of bundled waste straw bundles to be discharged can be freely changed such as three bundles, four bundles, five bundles, etc.

The control section 27 is configured to output a control signal for unlocking the solenoid 25 in conjunction with the turning of the main switch 28 from on to off.

With this configuration, when the main switch 28 is turned off to interrupt the reaping and harvesting work, the bundle of waste straw remaining on the dropper 8 is always released, so when the work is resumed, there is no waste straw on the dropper 8. You can accumulate from one time in any state.

Further, the control section 27 is configured to output a control signal for unlocking the solenoid 25 even when a clogging detection sensor 29 provided above the dropper 8 is activated.

The link hole 24a formed in the link 24 and connected to the lock member 22 is formed into a long hole, so that the lock member 2
2 can be unlocked manually, and the operating stroke of the solenoid 25 is short.
