Description

[Detailed description of the invention] The present invention provides a pair of left and right side-rotating type pulling devices in parallel at the front part of the reaping device, and a central front part between the parallel pulling devices and the side-by-side pulling device. A vertically rotating forced raking device is installed at the front of the left and right outer sides of the machine, respectively, and has locking claws that protrude from the lower front to the upper rear in a vertical plane along the direction of movement of the machine. Regarding machines.

In the reaping/harvesting machine having such a configuration, the forced raking device located between the pulling devices separates the subsequent introduced stem culm that is leaning against the previously introduced stem culm in the middle of being pulled up, so that This device was provided to enable good lifting, but conventionally, the length of the locking claw of this central forced raking device was determined by the length of the locking claws located on the left and right lateral outer sides. Because the structure was the same as that of the raking device, during the middle splitting operation, the two introduced stem culms were swung toward the central forced raking device as the raking action of the left and right forced raking devices was performed. When this happens, a part of the introduced stem culm may fall off from the locking claw, and as a result, there is a problem in that it tends to cause troubles such as lifting mistakes.

In view of the above-mentioned circumstances, the present invention avoids the above-mentioned fall of the stem culm from the locking claw during the middle splitting operation, and achieves the desired lifting action by the forcible raking device and the lifting device. The purpose of this device is to ensure that the device can be used reliably. It is characterized by being larger than the locking pawl of the forced raking device located on the outside.

That is, in the case of the present invention, during the middle splitting operation, the two introduced stem culms that have been swung toward the central forced raking device due to the raking action of the left and right forced raking devices are Since it can be reliably caught by the long locking claws of the central forced raking device, problems such as mistakes in raising caused by part of the stem culm falling off the locking claws, as in the conventional method, are avoided. By suppressing this as much as possible, the forcible scraping device and the lifting device can reliably and satisfactorily exhibit the intended lifting action. Moreover, the above-mentioned effects have been achieved by only making simple improvements to the locking pawl of the central forced raking device.

Embodiments of the present invention will be described below based on the drawings. Figures 1 and 2 show a combine harvester, which is an example of a reaping machine, and the clipper-type reaping device 1 engages with the base of two planted stems near the ground in front of it and moves them rearward and upward. Side-rotating type lifting devices 2, 2 are arranged side by side in the left and right direction with the tips of their lifting claws 2a, 2a facing each other,
Between the parallel pulling devices 2, 2 and the threshing device 3 mounted on the rear of the machine, the harvested stem culm is gradually changed to a sideways posture while being transported and fed to the threshing feed chain 4 of the threshing device 3. The vertical conveyance device 5 is installed, and locking claws 6a, 7a, 7a are provided at the front of the center between the parallel lifting devices 2, 2 and in front of the lateral outer portions of the parallel lifting devices 2, 2. Vertical rotary forced raking devices 6, 7, and 7 are provided, which are configured to project from the lower front to the lower rear along a vertical plane in the direction of movement of the aircraft.

The working length of the locking pawl 6a of the forced raking device 6 located between the parallel lifting devices 2, 2 is set as follows: In addition to making it larger than that of 7a,
Raking case 6A of the central forced raking device 6
The front edge and the front edge of the raking cases 7A, 7A of the left and right forced raking devices 7, 7 are located in the same plane in side view, and the lateral sides of the left and right raking cases 7A, 7A are arranged side by side. The lifting action of the lifting devices 2, 2 causes the stem culms raked up by both of these forced raking devices 7, 7 to be juxtaposed across the front surfaces of the lifting cases 2A, 2A of the lifting devices 2, 2. Guide plates 8, 8 are provided in series to guide the area.

Further, as shown in FIG. 3, the reaping device 1
Of the transmission pipes 10, 10 from the rear reaping gear case 9 to the pulling devices 2, 2 arranged in parallel, the transmission pipe 10 on the side of the threshing feed chain 4 and the corresponding raking case of the forced raking device 7. 7A
While constructing the transmission case 11,
The drive shafts 12, 13 and 13, 12 of the adjacent forced raking devices 7, 6 and 6, 7 are connected to the transmission cylinder member 1, respectively.
Transmission cylinders 15, 15, which are connected in a separable manner via 4, 14 and connected to the central scraping case 6A, and transmission cylinders 16, which are connected to the left and right scraping cases 7A, 7A. 16 are removably fixedly connected to each other.

In addition, when the central forced raking device 6 is removed, a straight transmission cylindrical body extends between the transmission cylinders 16, 16 and the drive shafts 12, 12 of the left and right forced raking devices 7, 7. and connect the intermediate transmission shaft.

In the figure, reference numeral 17 is a divider attached to the front lower end of each of the forcible scraping devices 6, 7, 7.
