Abstract

PURPOSE:To lower noise and obtain conveying chain hardly requiring oiling, by fitting and covering a roller consisting of reinforced plastic material into a connecting pin and coating an inside link plate with a resin material having abrasion resistance. CONSTITUTION:In a conveying chain 4, a inside link plate 1 is alternately linked with an outside link plate by a connecting pin 3 to constitute an endless band chain. A roller 5 consisting a reinforced plastic material a is provided to the connecting pin 3 by inserting and covering the material a and at least inside link plate 1 is coated with a resin material b having abrasion resistance. The roller 5 has oil-containing properties and exhibits effect equal to effect by oiling to each connecting pin and can be smoothly rotated for long period. The conveying chain 4 hardly generates noise, because the metal is brought into contact each other under pressure and causes no friction. Further, in the conveying chain, oiling operation is unnecessary and oil is not attached to conveying crop culm, because oil is not applied to the chain 4.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a conveyor chain for a harvester such as a combine harvester or a binder.

BACKGROUND OF THE INVENTION Conventional conveying chains of this type are generally constructed of a fully bent material, but this metal chain has a major drawback in that it generates noise due to friction of each component.

It also requires lubrication to ensure smooth operation.
The oil adhered to the husks of rice and wheat plants being transported, causing various problems such as spoiling the taste.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned deficiencies of the conventional type, and provides a conveyor system that generates relatively low noise during rotational drive and that does not require lubrication. I am trying to realize a chain device.

Means for Solving the Problem The present invention takes the following technical means to achieve the above object. That is, the inner link plate 1
and outer link plates 2 are alternately connected by connecting pins 3 to constitute an endless belt-shaped chain 4, and the connecting pins 3 are fitted with and covered with rollers 5 made of reinforced plastic material a, and at least This is a conveying chain device in which the inner link plate 1 is coated with a wear-resistant resin material.

Functions/Effects When the traveling device 6 is driven and the chassis 7 is moved one step forward, the culms in the field are harvested by the reaping device 8 located at a low position at the front, and the culms in the field are harvested by the one-plant origin conveying device 9 and the sugar part conveying device 10. It is supplied to the threshing machine 11.

Then, the culm is held and conveyed by the joint action of the conveying chain 4 and the fall rod 12 and moved to the straw removal side.

In such a process of transporting the shell culm, the conveying chain 4 is guided from the inside by the chain rail 13 and clamps the shell culm layer in a state in which it is pressed against the lever 12 which is tensioned by the spring 14. .

In this case, since the metals in the conveying chain 4 are not pressed against each other and the treatment is not carried out, very little noise is generated, and the work can be performed relatively quietly.

Further, since the roller 5 is made of carbon fiber material, which is a reinforced plastic material a, it has oil-retaining properties, and each connecting pin 3
It has the same effect as lubrication, and can run smoothly for a long period of time.

Therefore, not only is there no need for troublesome oiling work, but since the chain 4 is not oiled, there is no oil adhering to the conveyor culm, which has the unique effect of not impairing the taste. have

A threshing machine 11 is mounted on a chassis 7 having an embodiment traveling device 6.

The reaping frame 1115 has its rear portion pivotally connected to the front portion of the chassis 7,
It is configured by providing a reaping device 8, a culm pulling device 16, a stock head conveying device 9, and a sugar portion conveying device 10, respectively.

The conveying chain 4 is formed into an endless belt by alternately connecting inner link plates 1 and outer link plates 2 with connecting pins 3, and is provided along the handling opening 17 of the threshing machine 11.

In addition, 13 is a chain rail.

The clamping rod 12 is tensioned toward the chain 4 side by a spring 14, and is configured to be able to clamp the culm.
