Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a bucket conveyor in which a large number of buckets are attached to a chain that rotates in an endless manner.

(Prior art) This type of bucket conveyor has a high front wall and a slightly lower rear wall, and a bucket with a shielding collar protruding forward from the upper end of the front wall, and is made into an endless transition chain. Since a large number of shielding collars are installed in a row at intervals that cover the upper end of the rear wall of the front bucket 2, it is difficult to avoid problems when loading objects or when transporting items in a vertical section, as shown in Figures 7 and 8. At the same time, there is a drawback that the conveyed objects spill out from the gaps between the buckets, and furthermore, this accumulates in the casing, creating conveyance resistance and causing a decline in the functionality of the conveyor.

(Problem to be Solved by the Invention) The problem to be solved by the invention is to prevent conveyed objects from falling through gaps between consecutively installed buckets and to prevent functional deterioration.

(Means for Solving the Problems) The technical problem of the present invention to solve the above problems is to attach a seal plate that spans between the consecutive buckets and closes the gaps.

(Example) An embodiment of the present invention will be described based on the drawings.

Conveyor case A has a shape and structure well known in this type of technical field, and is provided with a pair of sprockets a and b on the side into which the conveyed object B is introduced and the side on which it is discharged, respectively, and an appropriate number of idlers in the middle. A sprocket c is provided, and a hopper e is opened on the input side, and a discharge port 7 is opened on the discharge side.

Furthermore, a guide plate d on which the transition chain 1 runs is provided on both left and right walls of the conveyor case A, and two transition chains 1 are endlessly constructed across the sprockets a and b and the idler sprocket c. d
make it run on top.

The transition chain 1 has a form and structure well known in this type of technical field, and is an endless chain with rollers 1a rolling on a guide plate d between a pair of sprockets a and b and an idler sprocket c in a conveyor case A. Two strips are constructed on the left and right so as to be rotated, and a large number of buckets 2 are hung at appropriate intervals across the left and right chains 1.

The bucket 2 is a box having a low front wall 2a and a high rear wall 2b, preferably a rectangular box with the upper portions of the front wall 2a and the rear wall 2b inclined toward the transfer direction of the transfer chain 1. Yes, its left and right side walls 2c
A support part 4 is provided and fixed to the transfer chain 1 via a connecting piece 5 to the support part 4, and a large number of buckets 2 are arranged in series.

A seal plate 3 for closing the gap between the front and rear buckets 2 is attached, and side plates 2d for closing the gaps formed on both sides between the buckets are further attached to the side wall.

The seal plate 3 is made of a flexible material such as synthetic rubber, and has approximately the same width as the front wall 2a of the bucket 2, and the rear wall of the front bucket 2 adjacent to the lower side of the front wall 2a. The gap created between the front and rear bucket bags 2 is closed by fixing them with a fixing device 6 such as a screw across the inclined part of the bucket bag 2b.

In addition, the seal plate 3 is installed so that the rotation center of the transition chain 1 and the bending center of the seal plate 3 coincide with each other as shown in FIG.
Since no tensile force or compressive force is generated due to the direction change of the bucket bag 2, the direction of the bucket bag 2 can be easily changed and its durability can be increased.

(Effects of the invention) With the above-described structure of the invention, there is no gap between the two buckets, and the objects will not fall out from between the buckets when loading the objects or transporting them in a vertical section. It is possible to prevent this from occurring, and also to prevent the accompanying functional deterioration.
Moreover, since the bending center of the seal plate and the rotation center of the transition chain coincide, there is no need to apply unreasonable tension or compression force when changing the direction of the bucket, making it easy to change direction, and improving durability. It is something that has.
