Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission device for a mowing binder.

[0002]

2. Description of the Related Art In the mode in which the traveling speed and the mowing speed are changed synchronously, the mowing speed cannot be reduced below a certain speed. It is necessary to limit or adjust the deceleration so that the vehicle is not decelerated below a certain speed. The present invention provides a transmission device for a reaping binder that is simple in operation and configuration.

[0003]

The present invention provides an engine E
Power is transmitted to the traveling wheels 2 and the reaping input shaft 13 via the speed change transmission mechanism 16 in the mission case 1, and is also transmitted to the grain culm elevating device 3 via the reaping input shaft 13 and the cutting blade device. 5, a cutting blade shaft 6 that is transmitted to 5, a cutting shaft 8 that is transmitted to the harvesting grain culm scraping device 7, a packer shaft 10 that is transmitted to the grain culm collecting packer 9, and a binding shaft 12 that is transmitted to the binding device 11. In the binder, there is provided a transmission device which is provided between the output shaft 14 of the mission case 1 and the mowing input shaft 13 and is provided with a mowing transmission device 15 capable of shifting from a standard mowing speed to a high mowing speed.

[0004]

[Operation and Effect of the Invention] By driving the engine E,
It is transmitted to the traveling wheels 2 via the speed change transmission mechanism 16 in the mission case 1, and the output shaft 14 and the reaping input shaft 13
It is transmitted to the side. When the traveling speed of the traveling wheels 2 and the reaping speed of the reaping input shaft 13 are synchronously changed by the gear shifting operation of the speed change transmission mechanism 16, the reaping speed becomes faster as the traveling speed becomes higher.

The transmission from the output shaft 14 to the reaping input shaft 13 can be changed by the reaper transmission 15. Normally, it is at the standard cutting speed, but when the grain stalk is lying, shifting to a high cutting speed will increase the transmission speed of the grain stalk raising device 3 etc., and the cutting speed relative to the traveling speed will be high. In particular, the raising operation in the grain culm raising device 3 can be performed accurately and smoothly, and even when the traveling speed is low, the raising can be performed similarly. Moreover,
The configuration can be simplified because the reaping transmission device 15 is provided only on the reaping input shaft 13 separately from the mission case 1.

Alternatively, a speed change transmission mechanism 16 and a mowing clutch 20 are provided, and the mowing clutch 20 can transmit power to the mowing output shaft 14. The speed change transmission mechanism 16 is a first speed, a second speed, or a third speed, and a back gear 21 is provided on a transmission system path to the wheel 2 side, which is switched by a forward / reverse switching gear 22 to be meshed and transmitted. Reference numeral 23 denotes a wheel transmission case that is vertically adjustable with respect to the mission case 1, and the axle 17 is mounted on the lower end of the wheel transmission case.

The transmission case 25 is connected from the front end of the mission case 1 with the pipe frame 24 interposed therebetween, and the transmission case 27 located under the front portion of the wheel 2 is connected by the transmission case 27. The output shaft 14 of the mission case 1 is transmitted from the gear shifting transmission device 15 in the gear shift transmission case 25, and from the gear shift shaft 29 through the transmission case 27 to the harvest input shaft 13 in the harvest transmission case 26.

The harvesting transmission 15 has a switching gear 28 on the output shaft 14 and a gear 3 on a transmission shaft 29 on the input shaft 13 side.
The input shaft 13 is set as a standard cutting speed by directly meshing with 0. Further, by engaging the switching gear 28 with the counter gear 31,
Is transmitted faster than the standard speed. These shift shafts 29
Also, the standard speed of the input shaft 13 is set to a transmission speed suitable for harvesting the undeveloped grain culm, and the high speed is set to a transmission speed suitable for harvesting the laid grain culm. Reference numeral 32 denotes a switching lever, which operates the shifting of the switching gear 28.

The grain culm raising case 33 is the transmission case 27.
A pull-up chain 34 that is placed in front of and stretched inside
Is transmitted by the raising shaft 4. The raising shaft 4 is connected to the transmission case 2
Interlock from 7 The pull-up chains 34 are provided with pull-up lugs 35 at regular intervals, project toward the grain culvert guide passage side, and raise the grain culverts in a certain posture while engaging the grain culms. The cutting transmission case 26 is provided with a cutting blade shaft 6 and a packer shaft 10 which are chain-transmitted from the input shaft 13, and the cutting blade shaft 6 is provided with a clipper type cutting blade device 5 provided at the front end of the cutting transmission case 26. To drive. The packer shaft 10 has the packer 9 above the binding transmission case 36 provided on one side of the reaping transmission case 26. The take-in shaft 8 and the binding shaft 12 are transmitted from the packer shaft 10.

The scraping shaft 8 transmits the scraping device 7 which is composed of a scraping chain or a star wheel 39 for scraping the grain stalks cut by the cutting blade device 5 into the binding portion 38 on the binding transmission case 36. Further, the packer shaft 10 drives the packer 9 to pressure-feed the grain culm scratched by the star wheel 39 to the binding portion 38. The bundling shaft 12 operates the T projection 40 which receives the pressure of the focused grain culm to operate the needle 41 for bundling the grain culm compressed in the bundling portion 38 and the knotting device 42 including a building, a holder, etc. The discharge arm 43 and the like for discharging the grain culms to the outside are transmitted.

In FIG. 5, the difference from the above example is that the weeding rod 44 on the side opposite to the binding transmission case 36 is inclined at an angle θ from the lateral end of the cutting transmission case 26 toward the front side.
The cutting blade device 5 is formed so as to project forward and passes through the lower surface of the lateral end portion of the cutting blade device 5 and projects forward. Therefore, the plant base A of the grain culvert is guided to the inside of the outer weeding rod 44.
Is guided to the inner side surface of the weeding rod 44 and is guided to the cutting working area of the cutting blade device. Since the grain culm is guided only within the cutting width of the cutting blade device 5 only by the shape of the weeding rod 44, the grain culm can be guided smoothly and the configuration can be simplified.

6 to 9, a wear preventing wire 51 provided along the binding cord guide groove 46 of the platform 45 in order to hold the cord end 50 of the binding cord 49 of the knotting device 42 at the time of starting the binding work. A free end is formed by bending the tip end portion 47 of the wear preventing wire 51 inside the terminal end 48 of the platform 45 by using an elastic wire such as a wire. By sandwiching and holding between the tip end portion 47 of the wear preventing wire 51 and the terminal end 48 of the platform 45, a safe and simple stringing operation can be performed.

On the packer 9 side of the binding portion 38, there is provided a needle 41 for winding a binding string 49 around the bundled grain culm,
On the opposite front side, a platform 45 and a knotting device 42 covered by the platform 45 are provided.
The knot device 42 uses the needle 41 to guide the string guide groove 4
6, a cord holder 52 for holding the binding cord 49 inserted through the cord 6, a cord cutter for cutting the cord end of the binding cord 49, and the like, and a building 53 for connecting both ends of the binding cord 49 to knot.

The wear preventing wire 51 has a bolt 5 at the base end.
In FIG. 4, it is fixed to the terminal end side of the platform 45 and is along the upper edge of the string guide groove 46. 55 is a string guide protrusion that projects upward from the lower edge of the string guide groove 46. A notch 56 is formed at the end 48 of the platform 45 so that the tip 47 of the wear-preventing wire 51 is fitted thereto so as not to be vertically displaced.

At the start of the mowing operation, the operator first passes the string end 50 through the needle 41 and then locks it at the tip end portion 47 of the abrasion preventing wire 51 at the terminal end 48 of the platform 45, and then the T projection 40. Turn it by hand to keep the binding clutch (illustration omitted) in the engaged state. Next, the operator separates from the binding device 11 and operates the harvesting clutch lever in the steering handle 18 to turn on the harvesting clutch 20, whereby the harvesting input shaft 13 is transmitted, and the binding device is moved. As a result, the binding cord 49 by the needle 41 is inserted into the knotted portion 42 through the cord guide groove 46 from the state where the cord end 47 is held by the tip end portion 47 of the wear preventing wire 51, and The binding string 49 that has passed through the string guide groove 46 is held by the string holder 52. This allows a cutting and binding action.

The tip portion of the binding cord 49 thus held by the cord holder 52 is cut by the cord cutter, but the cord end 50 held by the tip portion 47 of the wear preventing wire 51 before the binding is started. May remain intact unless this hold is removed.
