Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a binder transmission device for laterally feeding grain culms cut by a cutting blade and binding them with a binding device.

[0002]

2. Description of the Related Art Conventionally, in a binder in which a grain culm guide plate provided above a grain culm cut by a cutting blade is laterally fed as a guide and then fed to a binding device to bind the grain, one end side of the cutting blade is used. The drive shaft of the cutting and bundling device is provided upright, and power is transmitted from the drive shaft to the input part of the bundling device through the drive mechanism of the cutting blade and the transmission chain. Further, Japanese Utility Model Application Laid-Open No. 58-17091 is known to improve the maintainability by incorporating the above-mentioned transmission chain in a transmission case to prevent the accumulation and entanglement of mud and straw debris and the like.

[0003]

In the former transmission device of the related art, although the heavy binding device is arranged on one side of the cutting and binding device, the drive shaft or the like provided on the other side of the cutting device binds to the frame or the like. Since it was constructed in a lightweight structure in which it was pivotally supported via an air conditioner, if the left-right balance of the aircraft was a little, the running performance of the aircraft was poor because it tended to be biased toward the binding device side. In addition, since the transmission chain that transmits power to the binding device only covers the upper surface and the front surface with a simple cover, mud and straw are liable to adhere to the chain and the chain may come off and the cover may be clogged with mud. was there. Moreover, there is a problem that the chain drive causes noise and lacks durability. Further, the latter is effective in improving its drawbacks in terms of maintainability, etc., but the binding device still requires a tension device for chain extension to drive the chain, and the transmission case itself as a whole. It became wider and could not be made compact, which could lead to an increase in the weight of the aircraft. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a durable binder transmission device which is durable and has a structure that is trouble-free even during long-term use.

The vertical crankshaft (19) for driving the cutting blade (5) and the bevel gear device provided in the middle of the crankshaft (19) are internally provided, and the left and right inputs are connected to the bevel gear device at one end. The shaft (6) is placed substantially along the rear part of the cutting blade (5) above the cutting blade (5) by a certain amount above the cutting blade (5) so that a vertical space is provided between the shaft (6) and the other end. The device (10) is fitted and pivoted in the input part (7), and the binding device (10) is axially driven through the crankshaft (19), the bevel gear device, and the input shaft (6). That.

[0006]

Therefore, when performing the cutting and binding work with the binder which is transmitted from the midway portion of the gear case 15 of the present invention to the binding device 10 via the input shaft 6, the grain stems are extended by the carding device 4 as the machine body advances. Then, the cutting blades 5 at the rear are cut and the panicles are supported by the guide plate 11 and are sequentially transferred to the lateral binding device 10 in the lateral feed passage. Then, in the lateral feed passage, the packer 16 is transmitted from the back via the input shaft 6 to project and rotate, and the grain culms are accurately introduced into the bundling passage 9 to perform smooth and good bundling work. is there. In addition, the spiral blade 6a provided on the input shaft 6 is for engaging with force and laterally forcibly engaging the plant origin of the grain culm without disturbing the lateral feeding process.
