Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, in particular to a discharging device for bucket elevators. Background Art

[0002] A bucket elevator is a continuous conveying machine that uses a series of hoppers uniformly attached to an endless traction member to lift materials vertically. Bucket elevators use a series of hoppers attached to a traction chain or belt to transport bulk materials vertically or nearly vertically. Bucket elevators are available in three types: chain, plate chain, and belt. Bucket elevators are suitable for lifting materials from low to high locations. Material is fed into the hopper via a vibrating table, and the machine automatically and continuously operates to transport it upward. The conveying speed can be adjusted according to the conveying volume, and the lifting height can be selected as needed. The hoppers are designed and manufactured in-house. The PP non-toxic hopper makes this type of bucket elevator more widely used. All sizes are designed and manufactured according to actual needs. Designed to support vertical packaging machines and computerized metering machines, it is suitable for lifting and loading products such as food, medicine, chemical products, screws, and nuts. The machine can be automatically stopped and started by signal recognition from the packaging machine.

[0003] During use, the existing bucket elevator lifts the material to the top of the machine body, and then flips the bucket to make the material fall downward into the discharge pipe. However, when the lifted material has a certain viscosity and is discharged quickly, the discharge is often not clean, and the material sticks to the inner wall of the discharge pipe and causes blockage. The machine has to be stopped to clean the hopper, which is labor-intensive and time-consuming and reduces the discharge efficiency. Utility Model Content

[0006] By adopting the above technical scheme, a discharge pipe is set at the discharge port of the bucket elevator, and the cylinder piston rod is extended and retracted to drive the sliding rod connected to the piston rod to slide along the slide rail, so that the rotating part rotates to drive the other sliding rod to slide along the slide rail, driving the connecting rod to move left and right. When the connecting rod moves left and right, it drives the auxiliary plate to slide left and right along the slide groove, so that the two auxiliary plates are close to or away from each other. In the initial state, the two auxiliary plates are farthest apart, so that the discharge port is the largest, which is convenient for material discharge; when the discharge pipe is not smooth due to adhesion, the cylinder piston rod is contracted, and the two auxiliary plates are close to each other. The pressure between the two auxiliary plates is used to squeeze the material, and the compressed volume of the material is reduced and it is separated from the discharge pipe. The discharge pipe can be unblocked without stopping the machine, which has the advantages of convenient discharging, avoiding blockage and improving the unloading efficiency of the bucket elevator; a row of insertion plates is set on the inner side of the auxiliary plate.

[0012] The utility model is further configured as follows: the rear end of the auxiliary plate is slidably connected to the rear end of the discharge pipe.

[0013] By adopting the above technical solution, the auxiliary plate is slidably connected to the inner wall of the bottom of the discharge pipe and the rear end, so that the material adhering to the inner wall of the bottom of the discharge pipe and the rear end can be scraped off, avoiding the sliding resistance of the auxiliary plate caused by the adhesion of the material and reducing the dredging efficiency, which has the advantage of improving the unloading efficiency of the bucket elevator.

[0014] The utility model is further configured as follows: an inclined baffle is fixedly provided in the discharge pipe, and the baffle is located at the upper end of the auxiliary plate and is used to limit the material from entering the movable space formed by the outer wall of the auxiliary plate and the discharge pipe.

[0016] The utility model is further configured as follows: a base is provided on the support plate, and the cylinder is fixed on the base.

[0017] By adopting the above technical solution, a base is provided to achieve a fixed connection between the cylinder and the support plate.

[0018] The utility model is further configured as follows: elastic plates are provided on both sides of the upper end of the auxiliary plate, and the two elastic plates can completely cover the chute in a natural state.

[0019] By adopting the above technical solution, the elastic plate can be compressed. When the auxiliary plate slides left and right, the elastic plate can always completely cover the chute to prevent materials from flying out of the chute and flying around.

[0020] The utility model is further configured as follows: the bucket elevator body comprises a feed port and a drive motor located at a lower side of the bucket elevator body.

[0021] By adopting the above technical solution, a feeding port is set to feed the material, and a driving motor provides power to drive the conveying of the material.

[0022] The utility model is further configured as follows: the length of the material insertion column is 1 / 4 of the distance between the two chutes.

[0023] By adopting the above technical solution, the length of the insertion column is 1 / 4 of the distance between the two chutes, so as to prevent the tail end of the insertion column from colliding with the auxiliary plate.

[0024] The beneficial effects of the utility model are as follows: a discharge pipe is provided at the discharge port of the bucket elevator, and the cylinder piston rod is extended and retracted to drive the sliding rod connected to the piston rod to slide along the slide rail, so that the rotating part rotates to drive the other sliding rod to slide along the slide rail, driving the connecting rod to move left and right. When the connecting rod moves left and right, the auxiliary plate is driven to slide left and right along the slide groove, thereby realizing that the two auxiliary plates are close to or away from each other.
