Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a combine that emits a straw bundle in which combine straws after cutting and threshing are bundled in appropriate amounts so as to stand up against a field scene. It relates to a discharge device.

[Conventional technology]

A three-dimensional discharge in which a conveying and discharging mechanism composed of an endless chain and a sandwiching rod attached to the chain is arranged so that the starting end portion of the conveying and discharging mechanism looks into the discharging portion of the straw bundle from the straw binding mechanism in the combine. The device is, for example, Syokai 59-83320.
It is well known as described in Japanese Patent Publication No. 59-133038 and Japanese Utility Model Publication No. 59-133038.

Then, in this method, the straw bundle discharged from the binding mechanism is transferred while inheriting the position of the binding string in the straw bundle so as to be sandwiched between the endless chain and the pinching rod of the transport discharging mechanism. In the next step, the posture was changed so that the heavy stock base was on the bottom, and then the stock was dropped.

[Problems to be solved by the invention]

In Japanese Utility Model Laid-Open No. 59-133038, a mechanism for adjusting the force of clamping the endless chain and the endless chain of the endless chain is provided on the rear side of the endless chain and the endless rod in the transporting and discharging mechanism of the three-dimensional discharging device. . However, in this configuration, if an attempt is made to increase the pinching force of the rearward portion of the pinching bar, the front part of the pinching bar will float up relative to the rear part, and the straw bundle from the binding mechanism will be lifted. In the inheritance part, there is an inconvenience that the pinching force on the bundle is too weak and the bundle is displaced toward the tip side in the culm direction of the bundle and easily falls off.

In the case of reversing the above-mentioned configuration (when the mechanism for adjusting the clamping force of the clamping rod with respect to the endless chain is adjusted on the front side of the clamping rod), on the contrary, The rear part of the rod floats up relative to the front part, and the clamping force for the straw bundle on the terminal side of the transporting and discharging mechanism of the three-dimensional discharging device is weakened, and the posture of the stock base is lowered during transporting. There is an inconvenience that it falls to the ground before the completion. These phenomena are prominent when they are conveyed one after another such that a plurality of bundles of straw are present in one pin.

As described above, the above-described conventional three-dimensional discharge device has a structure in which the position for sandwiching the bundle of straw discharged from the binding mechanism by the endless chain and the sandwiching rod can be adjusted in the rod direction of the straw, namely, The starting end side of the pinching rod (the side that receives the straw bundle from the binding device)
By adjusting the strength of the pinching force with the and the initial distance to the endless chain on the starting end side of the pinching rod, the position where the straw bundle is pinched by the endless chain and the pinching rod is set in the rudder direction of the straw. The structure is not adjustable, and the clamping force cannot be adjusted individually for the rear part of the pin and the front part of the pin, so depending on the straw bundle, the position of the binding cord may be different. By holding the part closer to the root side than the endless chain between the endless chain and the holding rod, it is not possible to change the posture with the root side down during transportation, or more than the position of the binding cord. While sandwiching the part near the tip side, during the transfer of the straw bundle from the binding mechanism to the transport discharge mechanism, and during the transport of the straw bundle by the transport discharge mechanism,
There was a problem that the straw bundle unexpectedly dropped.

The present invention aims to solve this problem.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a transport and release mechanism including an endless chain and a pinching rod that is attached to the chain and is supported by a holding spring. In the three-dimensional discharge device arranged so as to look into the discharge portion of the straw bundle from the above, the sandwiching rod is composed of a front sandwiching rod and a rear sandwiching rod, and is slidable on a support frame in the transport and release mechanism. Of the supporting rods with holding springs mounted on the supporting rods with holding springs located in the middle of the straw-transporting direction by the endless chain, the ends of the both clamping rods are rotatably connected, The support rod with a holding spring rotatably connected to the starting end portion portion of the front clamping rod and the rear end portion portion of the rear clamping rod, respectively, holds each of the holding members with the supporting frame. Spring force adjusting plate for adjusting the spring force of the spring On the other hand, the support rod on the side of the starting end of the front clamping rod is provided with means for adjusting the distance between the starting end of the front clamping rod and the endless chain in a wide and narrow manner. It was done.

[Function and effect of device]

According to this structure, when the straw bundle is transferred from the binding mechanism to the delivery mechanism, the end position of the straw bundle between the endless chain and the front catching rod in the delivery mechanism moves from the position of the binding cord to the tip of the binding string. If it shifts to the part of the front part, the holding force between the endless chain and the front part can be increased by adjusting the spring force of the holding spring against the starting end part of the front part to increase the clamping force. It is possible to prevent the straw bundle from accidentally falling while the straw bundle is being inherited from the mechanism to the delivery mechanism.

Also, when the straw bundle is transferred from the binding mechanism to the transport discharge mechanism, the position where the straw bundle is clamped by the endless chain and the front pinching rod in the transport discharge mechanism is located closer to the root than the position of the strap. In the case of deviation, adjustment is made to widen the distance between the start end and the endless chain in the front clamping rod. Then, at the time of transfer of the straw bundle from the binding mechanism to the transport discharge mechanism, the straw bundle shifts to the stocker side due to its weight, so the position of the binding group in the straw bundle is changed to
It can be clamped by the endless chain and the front clamping rod.

Moreover, the clamping force can be adjusted independently for each of the front end portion of the front clamping rod and the rear end portion of the rear clamping rod. Therefore, by adjusting the clamping force of the front clamping rod and adjusting the distance between the starting end and the endless chain of the front clamping rod, the bundle of straws is transferred from the binding mechanism to the delivery mechanism. While smoothly performing, the clamping force of the rear clamping rod is adjusted separately from the strength of the clamping force of the front clamping rod so that the root side of the straw bundle faces downward toward the ground. The straw bundle can be securely conveyed until the posture is changed, and it is possible to prevent the straw bundle from accidentally falling during the conveyance of the straw bundle by the conveying and discharging mechanism.

Therefore, according to the present invention, when the straw bundle is transferred from the binding mechanism to the delivery mechanism, the straw bundle falls due to the pinching position of the straw bundle being displaced toward the tip side, and the straw bundle is dropped. Since it is possible to reliably prevent the occurrence of a situation in which the posture of the straw bundle cannot be changed due to the pinching position of the straw holder being displaced toward the root side, it is possible to improve the certainty of raising the straw bundle in the field scene. Play.
