Detailed Implementation

[0034] 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.

[0035] In this invention, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0036] See Figure 1-3The bucket elevator feeding device shown includes a chain conveyor and a cutter arranged in parallel. The chain conveyor includes two sets of conveyor chain plates 1 arranged in parallel, with multiple support members 3 for supporting the cut pieces 2 corresponding to each set of conveyor chain plates 1. The cutter includes a rotating shaft 18 and multiple cutters 4 arranged on the rotating shaft 18. The two ends of the rotating shaft 18 are provided with swing arms 17, and a support rod 16 is rotatably arranged between the swing arms 17. The support rod 16 is provided with a support groove 23, and a counterweight 20 is connected to the bottom of the support rod 16. The cutters 4 are arranged on the rear side of the swing arms 17 in the direction of rotation. A feeding box is provided on the side of the rotating shaft 18, and the front and rear sides of the feeding box are provided with stopping grooves 24 for stopping the two ends of the cut pieces 2.

[0037] Through the implementation of the above technical solution, the bucket elevator feeding device can be connected with the horizontal transmission of the cut piece 2 to achieve rapid cutting and transportation to the bucket elevator. The cut piece 2 is a cylindrical strip structure, such as a cylindrical structure. When the bucket elevator feeding device is running, the rotating shaft 18 is driven to rotate by an externally connected servo motor, such as clockwise. The cut piece 2 is transported to one end near the rotating shaft 18 by the transmission chain plate 1; the rotation of the rotating shaft 18 causes the cut piece 2 to be carried in the tray 23; the rotation of the rotating shaft 18 transports the cut piece 2 to the stopping slot 24; the rotation of the rotating shaft 18 uses multiple cutters 4 to cut the cut piece 2 that is stopped in the stopping slot 24; the cut piece 2, after being cut, falls into the feed inlet of the bucket elevator through the unloading box. Thus, after receiving the material on the chain conveyor, the cut piece 2 can be quickly placed and cut, making the transmission, cutting and feeding integrated, improving processing efficiency.

[0038] In this embodiment, to further provide a Chinese-style feeding box, the feeding box includes a box body 15. The front and rear sides of the box body 15 are formed with waste material feeding cavities 6 via partitions 12. A stopping groove 24 is disposed on the partitions 12. A cutting mechanism for cutting and correcting the ends of the cut piece 2 is disposed above the feeding box. The cutting mechanism can cut and correct the burrs at both ends of the cut piece 2. The cutting sequence is as follows: first, the two ends of the cut piece 2 are cut and corrected by the cutting mechanism, and then the cut piece 2 is segmented by the cutter 4, thus integrating the correction operation into one process. The cut waste material falls from the waste material feeding cavity 6, and the segmented material falls from the middle of the feeding box to the elevator inlet, achieving the separation of waste material and usable material.

[0039] In this embodiment, a receiving inclined plate 5 is provided between the partitions 12, located below the stopping groove 24. A side baffle 19 is provided on the side of the receiving inclined plate 5 facing the conveyor chain plate 1. The receiving inclined plate 5 and the side baffle 19 are provided so that the cut material falls onto the receiving inclined plate 5 and slides backward. In addition, the side baffle 19 provides lateral blocking.

[0040] In this embodiment, the side of the stop groove 24 facing the transmission chain plate 1 is set as a curved surface 25. Since the cutting piece 2 moves in a circular motion before entering the stop groove 24, in order to coordinate with the movement of the cutting piece 2 and allow the cutting piece 2 to smoothly enter the stop groove 24, the side of the stop groove 24 facing the transmission chain plate 1 is set as a curved surface 25.

[0041] In this embodiment, a first cylinder 14 is provided at one end of the feeding box facing away from the conveyor chain plate 1; a U-shaped frame 11 is connected to the end of the shaft 13 of the first cylinder 14, and a cutting unit is provided at the bottom of each end of the U-shaped frame 11; the cutting unit includes a second cylinder 10 and a pressing plate 26 provided at the bottom of the second cylinder 10, and an elastic pressing mechanism is provided on the bottom side of the pressing plate 26 above the stop groove 24; a cutting blade 8 is provided on the outside of the elastic pressing mechanism.

[0042] This configuration further provides a method for installing the cutting unit. When trimming and correcting the end of the cutting piece 2, the first cylinder 14 drives the shaft 13 to extend, positioning the elastic pressing mechanism directly above the stop groove 24. The extension of the second cylinder 10 presses the elastic pressing mechanism onto the cutting piece 2, while the cutting blade 8 trims and corrects the end of the cutting piece 2, achieving synchronization of pressing and trimming. Finally, the U-shaped frame 11 avoids the cutting segments of the cutting blade 4, facilitating the cutting of the cutting piece 2 when both ends are pressed, thus improving stability during cutting.

[0043] In this embodiment, to further provide an elastic pressing component, the elastic pressing mechanism includes a pressing block 7, and a plurality of elastic telescopic rods 9 are disposed between the pressing block 7 and the pressing plate 26. When the cutting blade 8 is cutting, the elastic telescopic rods 9 press against the cutting component and are in a compressed state.

[0044] In this embodiment, the bottom of the support rod 16 is provided with a plurality of screws 22, the counterweight 20 is provided with through holes for inserting the screws 22, and the bottom of the screws 22 is provided with a limiting nut 21. By setting the counterweight 20, the support groove 23 is always in an upward position, and the counterweight 20 is easy to disassemble and replace.

[0045] In this embodiment, to further provide a connection method between the support rod 16 and the swing arm 17, a central shaft is provided through the support rod 16, and the central shaft is inserted into the end of the swing arm 17.

[0046] Another aspect of the present invention provides a method for feeding a bucket elevator, which uses the aforementioned bucket elevator feeding device and includes the following steps:

[0047] S1, the cut piece 2 is transported to one end near the rotating shaft 18 via the transmission chain plate 1;

[0048] S2, by rotating the pivot 18, the cut piece 2 is carried in the bracket 23;

[0049] S3, the cutting piece 2 is transported to the stop groove 24 by the rotation of the rotating shaft 18;

[0050] S4, the cutting piece 2 that is stopped in the stop groove 24 is cut by multiple cutters 4 through the rotation of the rotating shaft 18;

[0051] S5, the cut pieces 2, after being cut into sections, fall through the feeding box to the feed inlet of the bucket elevator.

[0052] 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.

[0053] 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.

[0054] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
