Description

[Detailed description of the invention] (Purpose of the invention) The present invention relates to a scraper conveyor in which scrapers attached to an endless chain are arranged in a staggered manner to prevent conveyed materials from clogging the gap between the trough-like conveyance path and the end of the scraper. It is something.

(Industrial Field of Use) The present invention is suitable for use in the field of agriculture and stockpiling, such as transporting household feed etc. to high places and loading it onto trucks.

(Prior art) Conventionally, this type of scraper conveyor has scrapers attached at predetermined intervals to an endless chain hung on a sprocket, and feed, etc. is scooped up by the scraper running on a trough-like conveyance path, and discharged from an outlet. , to be loaded onto transport vehicles, etc.

(Problem to be solved by the invention) In the conventional device, the gap between both side walls of the trough-like conveyance path and both ends of the scraper is extremely small, so feed containing moisture enters the gap and hardens. Furthermore, clogging occurred, impairing smooth transfer, and furthermore, damage to the scraper, seizure of the motor, etc. occurred.

(Means for Solving the Problems) The present invention enables smooth upward conveyance of feed, etc. by a scraper without causing clogging between the scraper and both side walls of a trough-like conveyance path. In a scraper conveyor in which the material is transferred from a trough-like conveyance path using scrapers arranged at predetermined intervals on an endless chain and discharged from an outlet, the length of the scraper is set to be smaller than the width of the trough-like conveyance path. To provide a scraper conveyor which is shortened and arranged in a staggered manner alternately shifted to the left and shifted to the right.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the scrapers 1 of the scraper conveyor A are attached to an endless chain 2 at predetermined intervals, and the endless chain 2 is attached to a drive shaft 4 supported at both ends on the wall of a trough-like conveyance path 3. The drive side sprocket 5 is fixed, and the driven side sprocket 7 is fixed to a shaft 6 whose both ends are supported on the wall of the trough-like conveyance path 3 in an inclined manner, and rotates in the direction of the arrow in FIG.

The downward scrapers 1, 1, which rise obliquely with the rotation of the chain 2, are attached to the side walls 3a of the trough-like conveyance path 3,
It is configured to move upward in a conveying space defined by the lower part of 3a and the bottom wall part 3b, scoop up materials such as feed, and transfer them at the outlet 8 while moving upward.

As shown in FIG. 2, the scrapers 1, 1... have a length shorter than the width of the trough-like conveyance path 3, and are arranged in a staggered manner, alternating toward the left and right. The side walls 3a, 3a of the conveyance path 3 and the left and right ends of the scraper 1 are arranged to have wide and narrow gaps alternately, and the upright upper end surface 1a of the scraper 1 is the bottom wall of the trough-like conveyance path. 3b, an extremely narrow gap is formed between the two.

In this embodiment, the drive shaft 4 also serves as the rotating shaft 10 of the screw conveyor 9 of the feed mixing tank B.

In the figure, reference numeral 11 indicates a central transfer path provided with a screw conveyor 9, and 12 indicates paddle conveyors, which are provided in mixing and stirring paths 13, 13 disposed on both sides of the central transfer path 11, respectively.

(Function) Since the present invention is configured as described above, the paddle conveyors 12, 12 and the screw conveyor 9 stir and mix, and when the desired state is reached, the screw conveyor 9 transfers the mixture from the central transfer path 11 to the scraper conveyor A. The feed transferred to the lower part is scooped up by scrapers 1, 1, .

At this time, the feed that is successively scooped up and transferred upward by the scrapers 1, 1, etc. spills out from the wide gap between the side wall 3a, but the subsequent scraper 1 has a narrow gap between the side wall 3a. Immediately catch the feed spilled from the scraper 1, 1...
Since the feed is arranged alternately on the left and on the right, the feed that has fallen from the wide gap is transferred upward by the next scraper 1, and the feed in the narrow gap moves to the wide gap, and then the feed that has fallen from the narrow gap moves to the wide gap, and When the feed is about to clog, the scraper 1 escapes toward the wide gap by the allowance of the endless chain 2, and this action is repeated, so that the scrapers 1, 1... and the side walls 3a, 3a of the trough-like conveyance path 3 are The wide gap between the two is a good idea, and the feed won't get stuck in the narrow gap.
Moreover, the conveyance efficiency by the scrapers 1, 1, . . . does not decrease. The feed thus transferred upward in the trough-like conveyance path 3 by the scraper is discharged from the outlet 8 and can be loaded onto a waiting transport vehicle or the like.

The present invention is extremely effective for transporting feed containing moisture.

(Effects of the invention) In this invention, the scrapers are arranged in a staggered manner, alternately moving to the left and moving to the right, so that when feed becomes clogged between the side wall of the trough-like conveyance path and the edge of the scraper, the scraper can escape. There is no clogging of the scraper conveyor, and there is no problem of clumping of feed attached to both edges of the scraper, which occurs in conventional equipment, resulting in unreasonable operation. This has the effect of increasing the reliability of route operation, preventing motor seizing accidents, and not reducing conveyance efficiency.
