Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport chain device such as a combine raising device and a binder stock feed mechanism, and more specifically, to ensure the imparting of a transport force to a transported product by a chain protrusion. The present invention relates to a guide mechanism for preventing movement of a chain inside and outside a loop.

[0002]

2. Description of the Related Art For example, in the case of a binder
As shown in FIG. 4 of the Japanese Patent No. 516 publication, in order to prevent the chain (reference numeral 11) of the stock feed transverse feed mechanism from moving in the front-rear direction and linearly move, a guide mechanism (a pair of front and rear guide members The reference numeral 4) in Fig. 5 is provided so that a reliable lateral feed transfer force can be given by receiving the cutting culm.

[0003]

However, when the front and rear spacing of the guide mechanism is widened due to wear of the guide member or the like, there is a risk that the transport chain will oscillate back and forth, and transport will be disturbed. Since the front and rear guide members are uniquely fixed relative to each other, if they wear out, the parts must be replaced, and there is room for improvement in terms of economy.
In addition, a lateral feed force is applied to the conveyed object from a projection (reference numeral 10 in FIG. 5 of the above publication) of the chain. There is also a possibility that it may shake in a direction orthogonal to the rotation direction) and may not function sufficiently. A first object of the present invention is to obtain a guide mechanism capable of economically changing and adjusting the chain guide interval when the guide member is worn. The second object of the present invention is to realize the guide of the protrusion by an economical means.

[0004]

According to a characteristic constitution of the invention of claim 1, a conveying chain with a protrusion is wound around a pair of sprockets, and a conveying force is applied to a conveyed object by the protrusion between the both sprockets. In the guide mechanism of the transport chain device, in which a chain guide that regulates and guides the swinging motion of the transport chain is placed between a pair of sprockets so that the The first guide member for guiding and the second guide member for guiding from the outer side of the winding are configured to guide and guide the moving path of the transport chain, and the two guide members interact with each other between the contact action portions with the chain. Is provided with a connecting means for fixing the two guide members relative to each other so that the distance between the two can be changed and adjusted. That.

According to a second aspect of the present invention, there is provided a guide frame for fixedly supporting the first guide member, and the guide frame and the second guide member are bolted through an elongated hole formed in either one. The projection guide member for guiding the projection from the side thereof is detachably attached to the guide frame while being relatively fixed by the connecting means constituted by.

[0006]

In the structure of claim 1, due to the function of the connecting means,
Since the distance between the contact action portions of the first and second guide members with the chain, that is, the chain guide interval can be changed and adjusted, if these guide members are worn, it is sufficient to adjust them in a direction of narrowing the interval. There is no need to replace parts as in the past. Then, by removing one guide member from the other guide member, it is easy to perform clogging release, inspection, and maintenance.

According to the second aspect of the present invention, since the projection can be guided from the side by the projection guide member, the swinging movement of the projection due to the driving of the transport chain can be suppressed and a reliable lateral feed force can be applied to the transported object. Become. The projection guide member is the first
Since it is detachably attached to the guide frame for supporting the guide member, a dedicated support member is not necessary, and when the protrusion guide member wears, only the protrusion guide member needs to be replaced, and it is necessary to replace the entire frame. There is no. Even in this case, the chain guide interval can be adjusted by adjusting the position of the second guide member by the connecting means by the long hole and the bolt.

[0008]

As a result, the guide mechanism according to the first aspect of the present invention can be rationalized so that the chain guide interval can be economically adjusted, inspected, and maintained without replacing the parts.

Further, in the guide mechanism according to the second aspect, in addition to the above effect, the special support member has an advantage that not only the chain but also the swinging movement of the protrusion can be suppressed and a more reliable transfer function can be revealed. It could be enjoyed by a rational means that is unnecessary and replaceable.

The tip lateral feed mechanism 9B and the stock source lateral feed mechanism 9A constitute a lateral feed device 9.

As shown in FIGS. 2 to 5, the reaping transmission case 15 is formed by connecting and integrating three cases, first to third transmission cases 15A, 15B, and 15C. The first transmission case 15A includes a fourth transmission shaft 14, a transmission mechanism including a gear mechanism 21a from the fourth transmission shaft 14 to the cutting blade drive shaft 7a of the reaping device 7 and a chain mechanism 21b to the drive shaft 20 of the stock transverse feed mechanism 9A. In the state in which 21 is provided, it is arranged below the drive sprocket (corresponding to a drive wheel body) 6 a above the right raising device 1. The second transmission case 15B is detachably bolted to the first transmission case 15A, and
It is provided with a cutting blade drive shaft 7a and a transmission portion 22a for transmitting power to the binding device 8 from a lateral transmission shaft 22. The third transmission case 15C is the second transmission case 15B.
It is configured to be detachably bolted to, and to be provided with a lateral transmission shaft 22 and to be coupled to a binding case 8c of the binding device 8.

In the binding case 8c, the lateral transmission shaft 22 is linked to the packer drive shaft 23 by a bevel gear, and the third transmission case 1 in the second transmission case 15B is connected.
The connecting portion 24 with 5C and the connecting portion 25 with the third transmission case 15C in the binding case 8c are directly connectable. That is, the left and right ends of the third transmission case 15C have spigot structures, and the diameters thereof are the same, the inside and the outside are opposite to each other, and the mounting dimensions of the bolts are also the same. It is possible to fit and connect the connecting portions 24 and 25 by omitting 15C. The mowing transmission case 15 in the case of this direct connection is adjusted to the left and right dimensions when a single-row cutting binder including only the right raising device 6 is configured, and the third transmission case 15
