Then, the mounting member 9 of the side protector 8 is inserted and connected to the concave grooves 7 on both end faces in the left-right direction of each track strip, and further tightened by bolts 13 so as not to come off. A part of the adjacent side protectors overlaps in a state of being inclined at a wide angle to the rear part in the traveling direction.

Since the mounting member is provided inwardly with respect to the side protector 8 and a projection 10 is provided on the lower surface thereof, the projection 10 of the track strip 2 at the position of the front and rear sprockets is Teeth (11 ₁・ 11 ₂ … 11 _n )

〔The invention's effect〕

The present invention having the above configuration has the following effects. First, since the track strips constituting the endless track strip are connected by a joint with a head, the gap between the adjacent track strips is completely shut off, and the insertion of the constricted head and constricted recess of the joint is also performed. An endless track band having a constant shape is obtained without being disconnected or falling off by the connection. The joint connecting each of the track strips has elasticity, so that the joint can be adapted to a sprocket directly wound around the endless track and can be rotated in an arc.

In addition, since constricted concave grooves are formed at both ends in the connecting direction of the track strip and connected by the constricted head of the joint, the two are interchangeable and the length can be freely set by two types of parts. An orbital belt is obtained.

Next, in order to connect two or more track strips, one end of the elastic joint is previously formed integrally with one track strip, so that the endless track strip can be obtained with one type of component,
The connection between the integrally formed fitting and the track strip can be omitted by one step as compared with the above-mentioned aspect (2). In addition, since the pair of two track strips is connected in advance and one of the track strips is integrally formed with an elastic joint, the endless track band is formed by only one type of component of the track belt. As a result, the number of parts can be reduced and the number of assembling steps can be greatly reduced as compared with that of claim (2).

Subsequently, concave grooves are formed on the left and right end surfaces of the track strip, and mounting members at the lower portions of the side protectors facing the grooves are provided inwardly and inclined, and the protector is connected to the track strip via the mounting members. When the track strips are connected to each other, a part of the adjacent protectors is always overlapped, and the arc prevention member at the base of the adjacent side protector is joined by the gap preventing member.
It is a matter of course that the traveling of the endless track belt is straight-running, and even at the arc-rotated portion on the sprocket, the left and right end portions of the endless track zone are shielded without any gap. Therefore, even if the conveyed object placed on the mounting surface of the endless track belt is a powder or a granular material, it does not spill out from both sides, and the conveying operation is reliable and safe.

And since it can insert from the entrance of the both ends of a track strip in the left-right direction, the connection operation of the track strips is easy. Also, the cross-sectional shape of the groove of the raceway strip and the head of the elastic joint can be arbitrarily shaped, such as a circle or a polygon.

In addition, since the protrusion that meshes with the teeth of the sprocket is detachably mounted on the back side opposite to the mounting surface of the track strip, the chain mechanism protrudes outward on both the left and right sides of the endless track belt as in the past. Therefore, it is not necessary to provide the entire device, and the entire device can be made compact.

In addition, since the partition body of the same height as the side protector set at a height that does not drop on the plane of the track strip piece is integrally or separately erected, the mounting surface of the endless track belt is separated by the partition body. Can be formed in an arbitrary length in the traveling direction, whereby when the conveyor device is installed at an inclined position on an up plate or a down plate, the placed conveyed goods are not displaced, and it is ensured. Can be transported.
