[0040] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0041] The special term "exemplary" herein means "serving as an example, embodiment, or illustration". Any embodiment described as "exemplary" herein does not have to be construed as superior to or better than other embodiments.

[0042] In addition, for a better description of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail in order to highlight the gist of the present application.

[0043] Please refer to Figures 1 - 7 , in an embodiment of the present utility model, a feeding structure for lifting includes a feeding mechanism for lifting 4 installed on a vehicle frame 1 and located at the side end of a pulping mechanism 3. A folding feeding hopper 5 is provided at the feeding port position of the feeding mechanism for lifting 4. Wheels 2 are provided at the bottom of the vehicle frame 1 to facilitate the overall movement of the vehicle frame 1 and the components installed on the vehicle frame 1.

[0044] Specifically, the feeding mechanism for lifting 4 includes a lifting member, an L-shaped connecting frame 404, and a lifting and adjusting member 409. The lifting member is used to vertically lift and convey materials into the pulping mechanism 3. The L-shaped connecting frame 404 is fixed with a sliding frame 407 and is rotatably connected to the vehicle frame 1 at one end. The lifting member is slidably installed on the sliding frame 407. The lifting and adjusting member 409 is installed on the sliding frame 407 and is connected to the lifting member to adjust the vertical height of the lifting member so that the lifting member is docked with the pulping mechanism 3.

[0045] In this embodiment, by providing the L-shaped connecting frame 404 to connect the lifting member and the vehicle frame 1, the lifting member can be turned away when feeding is not required to eliminate the drawback that the vibration force generated during the operation of the pulping mechanism 3 directly acts on the lifting member, causing the lifting member to vibrate. At the same time, the provided lifting and adjusting member 409 can adjust the height of the lifting member, so that when the lifting member moves towards the pulping mechanism 3, it can be quickly docked with the pulping mechanism 3, which is convenient to operate and can eliminate the problem that the materials conveyed from the lifting member spill outside the pulping mechanism 3.

[0046] Exemplarily, in one embodiment, a connecting shaft 405 is fixed on the vehicle frame 1, and a collar is fixed at the end of the L-shaped connecting frame 404. The collar is sleeved on the connecting shaft 405 and rotatably connected to the connecting shaft 405. Adopting the direct sleeving method facilitates the quick separation of the lifting member from the vehicle frame 1, which is convenient for transportation and subsequent maintenance work.

[0047] Further, the lifting member includes a conveying box 401. A discharge pipe 4011 is formed at the side end of the conveying box 401. A circulating conveying unit is further included. The circulating conveying unit is arranged in the conveying box 401 and is used to convey materials into the discharge pipe 4011. The materials entering from the feeding port on the conveying box 401 are lifted upward by the circulating conveying unit to the position of the discharge pipe 4011, and then fall into the pulping mechanism 3 through the discharge pipe 4011, thereby realizing a quick feeding operation.

[0048] Among them, please refer to Figure 5 , the above-mentioned circulating conveying unit includes a first roller 410, a second roller 413 and a conveyor belt 412 connecting the first roller 410 and the second roller 413. A plurality of feeding hoppers 411 are equidistantly installed on the conveyor belt 412; the first roller 410 is rotatably installed in the conveying box 401 and is driven to rotate by a driving source installed on the conveying box 401; the second roller 413 is placed in the conveying box 401 and is connected to a tensioning and adjusting member 408 installed on the conveying box 401.

[0049] The driving source drives the first roller 410 to rotate, thereby driving the conveyor belt 412 to rotate in cooperation with the second roller 413. The conveyor belt 412 drives the feeding hoppers 411 thereon to move in a cycle in the conveying box 401. When the feeding hopper 411 moves to the position of the feeding port on the conveying box 401, the materials enter the feeding hopper 411. Subsequently, the current feeding hopper 411 moves upward. When the feeding hopper 411 rises to the highest position, the feeding hopper 411 starts to flip and pour the materials therein towards the discharge pipe 4011, and then enters the pulping mechanism 3 along the discharge pipe 4011. The next feeding hopper 411 continues the above actions, thereby realizing the feeding action of the materials.

[0050] Exemplarily, in one embodiment, the tensioning and adjusting member 408 includes a slider 4082 rotatably connected to the rotating shaft of the second roller 413. The slider 4082 is slidably connected to a chute 4083 fixed on the conveying box 401; a threaded rod 4081 threadedly connected to the extension plate on the conveying box 401 is further included, and the threaded rod 4081 is rotatably connected to the slider 4082.

[0051] When the conveyor belt 412 becomes loose, manually or through other auxiliary machinery, rotate the threaded rod 4081 to push the slider 4082 downward, so as to change the distance between the second roller 413 and the first roller 410, thereby realizing the tension adjustment control of the conveyor belt 412.

[0052] The above-mentioned drive source includes a motor 402 installed on the conveying box 401, and the output shaft of the motor 402 is rotationally connected to the rotating shaft of the first roller 410 through a transmission belt 403.

[0053] Exemplarily, in one implementation manner, the above-mentioned lifting adjustment member 409 includes:

[0054] An electric telescopic rod, a cylinder or a hydraulic cylinder installed on the sliding frame 407, and the movable end of the electric telescopic rod, the cylinder or the hydraulic cylinder is fixed to the conveying box 401. By setting the telescopic movement of the electric telescopic rod, the cylinder or the hydraulic cylinder, the vertical height of the conveying box 401 is driven to be adjusted, so as to facilitate docking with the pulping mechanism 3.

[0055] Exemplarily, in another implementation manner, please refer to Figure 2 and Figure 3 , two symmetrically arranged sliding plates 406 are fixed on one side of the conveying box 401 facing the sliding frame 407, and the sliding plates 406 are slidably connected to the sliding frame 407. The above-mentioned lifting adjustment member 409 includes a first wire roller 4091 and a second wire roller 4093 rotatably installed on the sliding frame 407. One end of the rotating shaft of the first wire roller 4091 is fixed with a rotating handle 4092, and a one-way locking member is arranged between the rotating shaft of the first wire roller 4091 and the sliding frame 407; it also includes a third wire roller 4094 rotatably installed between the two sliding plates 406, and a connecting rope 414 fixed to one end of the third wire roller 4094 is wound around the second wire roller 4093 and the other end is fixed to the first wire roller 4093.

[0056] By rotating the rotating handle 4092 to drive the first wire roller 4091 to rotate, thereby winding the connecting rope 414. Through the tension force between the connecting ropes 414, the distance between the second wire roller 4093 and the third wire roller 4094 is gradually shortened, so as to realize the upward movement of the sliding plate 406, thereby realizing the upward movement control of the conveying box 401. At the same time, the one-way locking member can ensure that the conveying box 401 will not move downward randomly after moving upward;

[0057] When the conveying box 401 rotates to the position of the pulping mechanism 3 following the L-shaped connecting frame 404, the one-way locking member is unlocked, and the rotating handle 4092 is rotated in the reverse direction in cooperation with the self-weight of the conveying box 401 to realize the downward movement of the conveying box 401, so as to realize the docking with the pulping mechanism 3.

[0058] The one-way locking member described above may adopt a ratchet mechanism. Specifically, the ratchet is fixed on the rotating shaft of the first line roller 4091, and the pawl is installed on the sliding bracket 407. Details of this specific embodiment will not be elaborated herein.
