Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically a bucket feeder. Background Technology

[0002] The main function of a bucket elevator is to lift materials from a low position to a high position and automatically load them into containers, achieving fast and efficient material conveying to meet the material conveying needs of the production line.

[0003] Chinese utility model patent application number CN201721855324.9 discloses a chain bucket automatic feeder. When the chain bucket assembly brings the buckets containing material to the first discharge port, the tipping baffles on the buckets are lifted by the first long shaft on the chain, causing the buckets to flip and dump the material. This requires tipping baffles on each bucket and multiple first long shafts on the chain to achieve the flipping of all buckets, resulting in a complex bucket flipping structure and inconvenient maintenance.

[0004] Therefore, it is necessary to propose a bucket feeder to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-4 As shown, a bucket feeder includes a housing 2. Two conveyor chains 9 are arranged parallel to each other on the inner side of the housing 2. Multiple feeding hoppers 7 are arranged in an array along the length of the two conveyor chains 9. The top sides of each feeding hopper 7 are rotatably connected to two conveyor chains 9. The conveyor chains 9 are arranged in a Z-shape on the inner side of the housing 2. A discharge port 1 and a feeding hopper 3 are respectively provided at the upper and lower ends of the housing 2 and the conveyor chains 9. A limiting baffle 8 is provided on the outer side of the top of the conveyor chains 9. The limiting baffle 8 is fixedly connected to the housing 2 and acts on the edge of the feeding hopper 7 to cause the feeding hopper 7 to rotate. Specifically, the conveyor chains 9 are limited and supported by several sprockets 10, one of which is driven to rotate by a servo motor.

[0027] During feeding, the material is fed from the feed hopper 3 into the feeding hopper 7. The conveyor chain 9 drives the feeding hopper 7 to convey upward. When the feeding hopper 7 moves to the top of the transfer cylinder 6, the limiting baffle 8 acts on both sides of the feeding hopper 7 to prevent it from rotating under its own weight. As the transfer cylinder 6 continues to convey, the feeding hopper 7 gradually flips over, pouring out the material, which is then discharged from the discharge port 1. After the feeding hopper 7 passes the limiting baffle 8, it rotates under its own weight, so that its discharge port faces upward, ready for the next loading. This cycle completes the feeding operation.

[0028] By rotating the feeding hopper 7 to the two conveying chains 9, the feeding hopper 7 is kept vertical during the conveying process to prevent material spillage. At the same time, by setting the limit baffle 8, it can automatically flip and discharge the material.

[0029] In some embodiments, to facilitate feeding, a transfer cylinder 6 is provided below the feeding hopper 3. The upper and lower sides of the transfer cylinder 6 are connected to the discharge port of the feeding hopper 3 and the inlet of the housing 2, respectively. A rotating cylinder 4, driven by a driving mechanism, is provided inside the transfer cylinder 6. The outer wall of the rotating cylinder 4 fits against the interior of the transfer cylinder 6. Several transfer grooves 5 are formed along the circumference of the outer side of the rotating cylinder 4. Preferably, the driving mechanism is a stepper motor. Specifically, the width of the transfer grooves 5 is smaller than the distance between the two material inlets at the upper and lower ends of the transfer cylinder 6.

[0030] When feeding material into the feeding hopper 7, the rotating drum 4 is driven to rotate by a stepper motor. When the transfer chute 5 rotates to the outlet of the feeding hopper 3, the material in the feeding hopper 3 falls into the transfer chute 5. As the rotating drum 4 rotates, the material follows the transfer chute 5 and moves within the transfer cylinder 6, finally being discharged from the discharge port at the bottom of the transfer cylinder 6 and falling into the feeding hopper 7. It is important to note that the rotation speed of the rotating drum 4 should be controlled to match the conveying speed of the feeding hopper 7 to ensure that there is a feeding hopper 7 below the transfer chute 5 to receive material each time it transfers material.

[0031] In some embodiments, through holes are provided at the top of both sides of the feeding hopper 7. The pins 11 of the conveying chain 9 corresponding to the through holes extend toward the feeding hopper 7 and pass through the through holes, and the feeding hopper 7 is rotatably connected to the pins 11. By arranging long pins 11 at intervals on the conveying chain 9 and rotatably connecting the feeding hopper 7 to the pins 11 of the conveying chain 9, the connection structure is simpler and easier to maintain.

[0032] Please see Figure 5 As shown, in order to avoid friction between the limiting baffle 8 and the feeding hopper 7, which would cause wear to the feeding hopper 7 or the limiting baffle 8, rollers 12 are rotatably connected to both sides of the top of the feeding hopper 7.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
