Detailed Implementation

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figures 1-5As shown: This invention provides a chain bucket conveyor, which includes a chain bucket elevator 1 and a feeder; the chain bucket elevator 1 includes a belt mounted on a support and multiple chain buckets 2 mounted on the belt; the feeder includes a frame 3, on which a storage bin 17 is mounted, and a guide plate 5 located below the storage bin 17 is mounted on the frame 3. The guide plate 5 is inclined, and a movable plate 4 is mounted at the lower end of the guide plate 5. A rotating shaft 6 is mounted on the side of the guide plate 5, and the movable plate 4 is rotatably mounted on the rotating shaft 6. A torsion spring 7 is sleeved on the rotating shaft 6. One end is connected to the rotating shaft 6, and the other end is connected to the movable plate 4. The lower end of the movable plate 4 is provided with a hinge seat 9, and a first rod 10 is hinged to the hinge seat 9. The lower end of the guide plate 5 is provided with a sliding sleeve 12, and a second rod 11 is slidably provided inside the sliding sleeve 12. The first rod 10 and the second rod 11 are hinged together. The end of the second rod 11 is provided with a connecting rod 13, and the connecting rod 13 is connected to a cover door 16 through a crossbar 14. The lower end of the storage bin 17 forms a material outlet, and the cover door 16 is slidably provided on the material outlet. The movable plate 4 is at least partially located above the chain bucket 2. During operation, materials are added to the storage hopper. Initially, the material inlet at the bottom of the hopper is closed. As the chain bucket rises, it contacts the movable plate, causing it to flip upwards. This flipping of the movable plate, via the first and second rods, displaces the cover, opening the material inlet and allowing material to enter. As the chain bucket continues to rise, the movable plate returns to its original position under the action of a torsion spring, and the material flows from the movable plate into the chain bucket below, completing the loading process. The chain bucket conveying equipment and method provided by this invention, compared to existing technologies, quantitatively slides material into the chain bucket, resulting in less destructive force on the chain bucket during loading and ensuring a quantitative flow of material without spillage. During loading, the material in the storage hopper can also be intermittently agitated by the rotation of the movable plate, preventing obstructed material flow and eliminating the need for additional power, thus greatly improving operational efficiency.

[0032] In a preferred embodiment of the present invention, in order to prevent material from flowing out from the gap between the movable plate and the guide plate during the conveying process, the upper surfaces of the movable plate 4 and the guide plate 5 are covered with elastic rubber pads 8, so that the elastic rubber pads 8 can bend with the movable plate 4.

[0033] In a preferred embodiment of the present invention, in order to further limit the sliding of the cover door, slide rails 15 are provided on both sides of the feed inlet, and the cover door 16 is slidably engaged on the slide rails 15.

[0034] In a preferred embodiment of the present invention, in order to enable the second rod to slide smoothly back and forth within the sliding sleeve, a plurality of linear bearings are provided inside the sliding sleeve 12, and the second rod 11 is slidably disposed within the linear bearings.

[0035] In a preferred embodiment of the present invention, in order to agitate the material in the storage bin and avoid poor material discharge, a stirring roller 20 is rotatably provided in the storage bin 17.

[0036] In a preferred embodiment of the present invention, the stirring roller 20 extends at least partially beyond the storage bin 17 and is connected to a gear 18. A rack 19, meshing with the gear 18, is provided on the outer side of the storage bin 17, and the rack 19 is connected to the connecting rod 13. The reciprocating intermittent displacement of the second rod drives the rack to reciprocate, thereby enabling the gear to drive the stirring roller 20 to rotate in both directions, thus achieving the effect of stirring the material and improving the smoothness of material feeding.

[0037] In a preferred embodiment of the present invention, in order to further limit the displacement of the rack, the outer wall of the storage bin 17 is provided with a sliding track, and the rack 19 is slidably engaged on the sliding track.

[0038] In a preferred embodiment of the present invention, the chain bucket elevator 1 includes a support frame, rollers are respectively provided at both ends of the support frame, a belt is wrapped around the rollers, a motor is provided on the support frame, the output shaft of the motor is connected to the rollers, and a plurality of chain buckets 2 are spaced apart on the belt.

[0039] The present invention also provides a material conveying method, wherein the material conveying method utilizes the above-mentioned chain bucket conveyor;

[0040] 1. Add the material into storage silo 17;

[0041] 2. In the initial state, the material outlet at the lower end of the storage bin 17 is closed;

[0042] 3. As the chain bucket 2 rises, it comes into contact with the movable plate 4 and causes it to flip upwards. At this time, the flipping of the movable plate 4 causes the cover door 16 to move through the first rod 10 and the second rod 11, thereby opening the material inlet and allowing the material to enter the movable plate 4.

[0043] 4. As the chain bucket 2 continues to rise, the movable plate 4 returns to its original position under the action of the torsion spring, and the material flows from the movable plate 4 into the chain bucket 2 below, completing the feeding process.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
