Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a pulling device in which a plurality of tines are attached to an endlessly rotating chino.

The pulling device in conventional combines is either a vertical type (a type in which an endless rotating chain is suspended from a sprocket that rotates around a horizontal horizontal axis) or a horizontal type; Because of the structure in which the lifting device is pivoted so as to be swingable only in the left and right directions, it is impossible to extend the lifting device rearward and upward and use this extended portion for transporting the tips.

That is, the reaped husk is raised to a predetermined vertical position by the tines that move rearward and upward in a horizontally protruding position, and the stump base is cut off. While the grains are being held and conveyed to the foot chain of the threshing section, the tips of the ears are held and conveyed by the upper conveying device towards the alligator of the threshing section, thereby gradually being controlled to fall sideways.

Therefore, even if the movement path of the tines in the lifting device is extended rearward and this extension is used as an upper conveyance device,
As mentioned above, the posture of the cut culm changes from a standing position to a sideways posture suitable for supplying the tip to the crocodile, so the tines and the cut culm gradually become parallel, and the tip of the cut culm is no longer locked by the tines. This cannot be avoided.

In addition, if a pinch rail is provided along the movement path of the tines to ensure that the tip of the ear is secured by the tines, the tip of the cut culm will be held and conveyed by both of these rails. The straining by tines and pinning rails causes undesirable situations such as grain shedding and ear breakage.

The present invention provides a lifting device that can avoid such inconveniences.

An embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 to 3, an endless rotating chino 2 is suspended from a sprocket (not shown) that is mounted on a lifting case 1.
A plurality of tines 3 are pivotally connected to each other through a universal joint structure A having a first pivot shaft 4a and a second pivot shaft 4b that are perpendicular to each other so as to be swingable in the left-right direction and the up-down direction. The case 1 has a bottom surface S1 and both side surfaces S2, . S3
A tine guide 5 is provided which slides into contact with the tine guide.

The front half of the tine guide 5, that is, the part where the tines 3 should perform the lifting action, opens sideways as shown in Figure 1, and the rear half opens upward as shown in Figures 2 and 3. The opening is made into a smoothly curved shape so that the transition from the front half side to the rear half side becomes a horizontal opening and gradually an upward opening, and on the front half side, the tines 3 are restricted to a posture protruding in the left and right direction, On the latter half side, the tines 3 are restricted to an upwardly protruding position.

In the figure, 6 is a cheno guide that slides on a part of the roller of the endless rotating chino 2, 7 is a guide support, and the lifting case 1
It is constructed in

According to the above configuration, as shown in FIGS. 4 and 5, in the first half of the outward journey of the endless rotary chino 2, the tines 3 protrude in the left-right direction from near the ground in front of the cutting to rearward and upward. It moves and acts to raise the lodging culm.

After the lifting action is completed, the tines 3 assume an upward posture and move rearward while maintaining the upwardly protruding posture.

Therefore, not only while the fallen husk culm in the field is raised to an upright position suitable for reaping, but also when the reaped husk culm changes from an upright position to a lateral down position suitable for supply to the threshing section's crocodile, the tine 3 It is possible to securely lock the shell to the culm.

That is, the tips of the cut husk culms, which are caused by the tines 3 protruding in the left and right direction, are cut off at the stock end, and the stock end section is transferred to the foot chain of the threshing section by a lower conveyance device (not shown) and a lifting conveyance device (not shown). While the grain is being held and transported to the threshing section, the tines 3, which move in an upwardly protruding position, reliably lock and transport the grain toward the alligator in the threshing section.

6 and 7 show another embodiment, in which the base 3 of the tine 3
A is made of cedar bark in a round shape and is characterized in that it is configured to be smoothly guided along the curved portion of the tine guide 5 shown in FIGS. 1 to 3.

Other configurations and operations are the same as those of the previously described embodiments, so illustrations and explanations will be omitted.

The present invention has the above-mentioned configuration, and in order to change the tine from a posture protruding in the left-right direction to a posture protruding upward during its outward journey, the present invention is caused by the tine moving in a posture protruding in the left-right direction. The tip of the cut culm can be reliably held and transported by the tines that have changed to the upwardly protruding position, and no clamping rails are required, so there is no chance of shedding or breakage due to straining of the tip. This is because the inconvenience can be avoided.

In the embodiments, a vertically rotating type lifting device has been described as an example as shown in the drawings, but the present invention can also be applied to a horizontally rotating type lifting device.
