Description

FIELD OF THE INVENTION The present invention relates to a combined straw delivery device.

Conventional technology During harvesting work with a combine, it is necessary to turn the aircraft when moving from one harvesting stroke to the next harvesting stroke. It is something to do. At this time, if the airframe is backed up while releasing the bundle of straw bundles into the field, the straw bundle will be trampled on by the crawler, so it will not be possible to use the sharp straws or it will be rolled into the running part of the machine. Defect occurs.

For this reason, conventionally, an opening / closing mechanism for opening and closing a grain culm receiver provided at the rear of the machine body and a locking device for locking and unlocking the opening and closing mechanism are provided, and the opening and closing mechanism is locked when the machine body travels. A dropper control device is known (Japanese Utility Model Publication No. 56-50222).

However, in the above-mentioned known example, since the conveying device for accurately transferring and discharging the straw bundle to the already cut land side is not provided, the discharged straw bundle becomes uncut side. Not only was there a problem in the next process due to falling into the air, but there was also the problem that the structure became complicated.

Means for Solving the Problems Therefore, the present invention provides a combiner in which a pretreatment device that can move up and down freely is provided in the front part of the machine body, and threshing parts are arranged behind them, respectively, and a binding machine is mounted behind the threshing parts. A transport discharge device for transporting and discharging the straw bundle to the cut land side is attached to the front of the binding machine in the straw discharge direction, and the transport discharge device stops the transport discharge action of the straw bundle and the straw bundle is stopped in the stopped state. A retention holding means for temporarily retaining the retention and release means of the transport and discharge apparatus is provided, and the retention and retention means and the pretreatment device are connected so that the retention and retention means operates in conjunction with the rise of the pretreatment device. By doing so, the above problems are solved.

Action During the mowing work, the pretreatment device is lifted (lifted up) when one round of mowing is completed and the machine is rotated on one side of the field, but when the pretreatment device is raised, the retention holding means is interlocked. Is activated to stop the carrying and discharging action of the carrying and discharging device, and the straw bundle discharged from the binding machine is temporarily held in the carrying and discharging passage of the carrying and discharging device. After that, when the pretreatment device is lowered in the next mowing process, the operation of the retention holding means is released and the transport release device restarts the transport release action, whereby the straw bundles retained and retained are sequentially released to the field. . Therefore, since the straw bundle is not released to the field during the traveling of the aircraft, the straw bundle is not trampled by the crawler even when the aircraft is moved back during traveling.

The first embodiment is a combine pretreatment device, which is mounted to be movable up and down by a hydraulic cylinder 4 provided between a machine body frame 2 and a pretreatment frame 3.

To be able to do. The binding machine 11 is composed of a scraping tine 13, a sweeper 14, a needle 15, a knot portion 16 and the like. Reference numeral 17 denotes a finger-type conveying / discharging device provided in the front of the binding machine 11 in the straw discharging direction, and is provided in a conveying / discharging passage a formed between the straw receiving plate 17a and the elastic guide rod 17b extruded by the sweeper 14. The finger 17c that constantly rotates while receiving the light is emitted to the cut field side of the field. 18 is a holder for the finger drive shaft 18a, and the drive shaft 18a
Is connected to a counter shaft 19 meshing with the drive shaft 18a through a spline-engaged clutch pawl 20 and an input chain ring 21 loosely fitted to the counter shaft 19 as shown in FIGS. The shift pawl 20 pushes back the clutch pawl 20 which is constantly urged toward the clutch inward side by the return spring 22 to disengage the clutch. Is configured. Then, the straw bundle b discharged from the binding machine 11 is transferred to the transport discharge device 17.
The following retention holding means for temporarily holding is provided. That is, when the clutch of the transport discharging device transmission section A is disengaged, the transport discharging action of the transport discharging device 17 is stopped, and the straw bundle b discharged from the binding machine 11 is transferred to the transport discharging path a of the transport discharging device 17 as described later. It is configured to be retained inside.

Incidentally, if the finger 17c is configured so as to stop in a state of projecting upward as shown in FIG. 3 when the clutch of the conveying / discharging device transmission section A is disengaged, the finger 17c is arranged in the conveying / discharging passage a of the straw b. Since the stopper function of closing the terminal end portion is fulfilled, the straw bundle holding function, which will be described later, is performed more reliably.

By the way, the above-mentioned straw bundle retention and holding means provided in the conveying / discharging device 17 is linked to the pretreatment device 1. When the pretreatment device 1 is raised, the conveying / discharging device 17 stops the conveying / releasing action of the straw bundle. The straw bundle is retained and held by the transporting and discharging device 17. Shown is a wire
25 is a structure in which both 1 and 17 are connected. That is, one end of the wire 25 is fastened to one side of the pretreatment frame 3, and the other end is fastened to the upper end of the shifter 23 of the power interrupting mechanism 24.

In the figure, 26 is a packer, 27 is a door, 28 is a knotter building, 29
Is the clutch shaft of the binding machine 11, 30 is the needle crank shaft, 31
Is a self-removal counter shaft, 32 is a rooting plate rod, and b is a straw bundle.

6 to 12 show another embodiment, which uses an endless type conveying and discharging device 17 ',
A switch 33 for detecting the elevation of the pretreatment device 1 is provided at the front of the machine body, and when the pretreatment device 1 rises, the switch 33 is turned on and the electromagnetic clutch 34 is activated, whereby the parallel link 35 is passed. The transport pawl guide 37, which is supported by the case 36 of the transport ejector 17 'so as to be movable up and down, lowers and the transport ejector
The conveying claw 38 on the latter half of the 17 'rear side is laid down to stop the conveying and discharging action at this portion, and the straw bundle b is temporarily stored at this stopping portion. In the present embodiment, when the pretreatment device 1 is raised, the transport discharging device 17 stops the transport action entirely, but in this embodiment, the transport discharging device 17 'partially suspends the transport action. To do.

Reference numeral 39 denotes a drive shaft of the conveying / discharging device 17 ', which is guided from the transmission case 40 of the binding machine 11 and is constantly rotating. 41 is a guide rod,
42 is a tip receiving rod, 43 is a main switch, and c is on the side of the cut land.

In the above-described configuration, during the mowing operation, when finishing one mowing process and moving to the next mowing process, the pretreatment device 1 is raised (the mowing is interrupted) and the machine is rotated (turned). When the pretreatment apparatus 1 is raised, the wire 25 is pulled, and the shifter 23 rotates in the counterclockwise direction in FIG. 4 about the fulcrum shaft 23a. For this reason, the clutch pawl 20 moves in the direction away from the input chain wheel 21 against the return spring 22, and the clutch of the transfer / release device transmission unit A is disengaged. As a result, the transmission of power to the carrier discharging device 17 is cut off and the rotation of the finger 17c is stopped. Therefore, the straw bundle b extruded by the sweeper 14
Is not released to the field, but the receiving plate 17a and the elastic guide rod 1
In the state of being sandwiched between 7b, several bundles are collectively retained and held in the conveyance discharge passage a (see FIGS. 1 and 3). Therefore, when the airframe is backed, the straw bundle released to the field is crawled by the crawler 9
The inconvenience of stepping on to attach mud or winding straw around a rotating part such as a crawler is eliminated. Further, unlike the conventional one, there is no danger that the work assistant hurriedly removes the straw bundle each time, which is safe.

Now, when the traveling is completed and the pre-treatment device 1 is moved down into the forward movement / mowing process, the clutch of the transfer / release device transmission section A is engaged and the finger 17c is rotated again, so that the transfer / release path a is temporarily moved. The straw bundle b held in the field is sequentially released to the abandoned side of the field.
