[0030] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Example:

[0033] See Figures 1-4This embodiment provides a port stacker, including:

[0034] The machine body assembly is equipped with a belt conveyor assembly 13 for transporting materials;

[0035] The support frame 2 is rotatably mounted on the receiving end of the machine body assembly. The support frame 2 is equipped with a traveling wheel and a support component 12 capable of telescopic movement. When the support component 12 supports the ground, the traveling wheel on the support frame 2 is suspended in the air.

[0036] A height adjustment component is disposed between the receiving end and the unloading end of the machine body assembly and located on the bottom surface of the machine body assembly. The height adjustment component includes a support plate 5, a sliding block 9, a push-pull rod 10 and a drive component. The upper end of the support plate 5 is rotatably connected to the machine body assembly, and its lower end is provided with a traveling wheel. The sliding block 9 is slidably disposed on the machine body assembly and is driven by the drive component. The two ends of the push-pull rod 10 are rotatably connected to the lower end of the support plate 5 and the sliding block 9, respectively.

[0037] Preferably, in this embodiment, the traveling wheels on the support frame 2 are omnidirectional wheels 3, and the traveling wheels on the support plate 5 are rollers 6. By setting omnidirectional wheels 3 on the support frame and rollers 6 on the support plate 5, the entire stacker can be moved, making it convenient to transfer the stacker to different locations. The omnidirectional wheels 3 are set on the support frame, which allows for easy adjustment of the stacker's traveling direction, thereby achieving the purpose of adjusting the unloading end position.

[0038] In this embodiment, the sliding block 9 is driven by the drive unit to move, which can cause the support plate 5 to swing around the upper rotation point. The swing of the support plate 5 can change the height position of the unloading end, thereby achieving the purpose of adjusting the height of the unloading end, so that the unloading end and the material pile are kept within a small height difference range, reducing dust.

[0039] Preferably, the rotating connection in this embodiment refers to a pin hinge or a bearing connection; of course, those skilled in the art may also use other structural forms to achieve the rotating connection, which will not be listed in this embodiment.

[0040] See Figure 1In this embodiment, the machine body assembly includes a frame body 1 and a mounting frame 4 disposed on the frame body 1. The belt conveyor assembly 13 and the support frame 2 are both disposed on the frame body 1. The support frame 2 is rotatably connected to the receiving end of the frame body (e.g., by hinge or bearing connection) to provide the necessary degree of freedom for adjusting the height of the unloading end of the stacker. The height adjustment assembly is disposed on the mounting frame 4. Specifically, in this embodiment, the frame body 1 is a frame structure, which can be welded from materials such as steel pipes and angle steel. The mounting frame 4 includes a top plate and side plates. The top plate is fixedly connected to the frame body 1 and located on the bottom surface of the frame body 1. Side plates are disposed around the top plate, thereby forming a box structure with an opening at the bottom. The internal space of the mounting frame 4 is a mounting groove 7 for the installation of the sliding block 9 and the space required for its sliding. Of course, in some embodiments, other structural forms and other materials may be used to prepare the machine body assembly. This embodiment does not exemplify all possible situations.

[0041] Preferably, the body assembly is provided with a guide structure for guiding the movement of the sliding block 9. This guide structure enables the sliding block 9 to move linearly, ensuring smooth and stable movement. Specifically, in this embodiment, the guide structure is as follows: guide grooves 15 are provided on both sides of the mounting frame 4, and guide blocks 16 are provided at both ends of the sliding block 9. The sliding block 9 is disposed in the mounting groove 7 of the mounting frame 4, and the guide blocks 16 at both ends are respectively disposed in the guide grooves 15, thereby guiding the movement of the sliding block 9. Further, in some embodiments, the guide structure may be a slide rail assembly, generally including a slide rail and a slider. After the slide rail is fixedly mounted on the body assembly (i.e., the mounting frame 4), the sliding block 9 is fixedly connected to the slider, thereby also guiding the movement of the sliding block 9.

[0042] See Figure 2 In this embodiment, the driving assembly includes a lead screw 8 and a first driving member 11. The lead screw 8 is rotatably mounted on the machine body assembly (i.e., the mounting frame 4) via a bearing, and one end of the lead screw 8 is connected to the output end of the first driving member 11. The sliding block 9 is sleeved on the lead screw 8. The first driving member drives the lead screw to rotate, thereby driving the sliding block 9 to slide along the length direction of the lead screw, achieving the purpose of linear movement of the sliding block 9. Furthermore, the structure in which the sliding block 9 moves along the length direction of the lead screw 8 with the rotation of the lead screw is common knowledge in the art, and a ball screw can be directly purchased. The lead screw nut and the sliding block 9 can be fixedly connected, or the sliding block can be the lead screw nut. Furthermore, the first driving member is a motor.

[0043] Preferably, in some embodiments, the drive component may be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The fixed end of the drive component is fixedly connected to the body component (i.e., the mounting frame 4), and the movable end of the drive component is connected to the sliding block 9 to achieve the purpose of driving the sliding block to move. Of course, in some embodiments, the drive component may also adopt other structural forms. For example, it is also feasible to use a gear and rack to drive the sliding block 9 to move. Those skilled in the art can flexibly adjust and change the structural form of the drive component.

[0044] See Figures 1-4 The support assembly 12 includes a ground support block 123 and at least one telescopic member 122. The telescopic member 122 is mounted on the support frame 2 and its movable end is connected to the ground support block 123. The telescopic member 122 extends and retracts, thereby achieving the effect of the ground support block 123 supporting the receiving end and ensuring the stability of the stacker during operation. Furthermore, the telescopic member 122 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0045] Furthermore, the bottom surface of the support block 123 is provided with an anti-slip pad 18, which can improve the anti-slip effect and ensure the stability of the stacker during operation; preferably, the anti-slip pad 18 is set on the bottom surface of the support block 123 by adhesive bonding, which facilitates the maintenance and replacement of the anti-slip pad in the later stage.

[0046] Furthermore, the support frame 2 is provided with a mounting groove 121 for accommodating the telescopic member 122 and the ground support block 123. The mounting groove 121 is located on the bottom surface of the support frame 2, thereby reducing the required height of the support frame 2.

[0047] See Figure 1 and Figure 3 The support frame 2 is provided with a traction plate 19 on the side away from the machine body components. The traction plate 19 is provided with a linkage port 20, which is convenient for the equipment to be moved by inserting into the linkage port 20 of the traction plate 19 through the corresponding connector, so as to provide a force point for the stacker to be moved.

[0048] See Figure 1 and Figure 2 The conveyor belt assembly 13 includes rollers 131, a conveyor belt 132, and a second drive unit 133. Rollers 131 are rotatably mounted on both the receiving and unloading ends of the machine body assembly (i.e., the frame body 1). The conveyor belt 132 is fitted onto two rollers 131. The output end of the second drive unit 133 is connected to one of the rollers 131. The second drive unit 133 drives the connected roller 131 to rotate, thereby moving the conveyor belt 132 to achieve the purpose of material conveying. Further, the second drive unit 133 is preferably a motor.

[0049] Furthermore, the machine body assembly is provided with a material guide trough 14 at the receiving end. The material guide trough 14 is installed on the machine frame body 1 to facilitate the collection of materials onto the conveyor belt 132 at the receiving end during unloading.

[0050] In this embodiment, the stacker is used by the universal wheels 3 and rollers 6 in contact with the ground to improve its ease of movement. When the stacker is moved to a suitable position, the telescopic component 122 is activated to drive the ground support block 123, so that the ground support block 123 contacts the ground and the two universal wheels 3 are suspended in the air, thereby fixing the equipment. This improves the ease of movement and ensures the stability during use.

[0051] During material stacking, materials are unloaded into the feed chute 14 (this can be done manually, by a forklift, or by a belt conveyor, depending on the on-site process). The second drive unit 133 is activated to drive the rollers 131 to rotate. The tension of the two rollers 131 on the conveyor belt 132 causes the conveyor belt to work, and the material is transported to the unloading end along with the conveyor belt 132, thus realizing material stacking. During material stacking, the first drive unit 11 drives the lead screw 8 to rotate, causing the sliding block 9 to move. Under the action of the push-pull rod 10, the swing angle of the support plate 5 is adjusted. By adjusting the angle of the support plate 5, the balance angle of the stacker can be adjusted. During the material stacking process, the unloading end of the belt conveyor assembly 13 is first lowered to be close to the ground. As the material accumulates, the first drive unit 11 is activated to gradually push the sliding block 9. The rotation of the support plate 5 causes the position of the unloading end at the head of the frame body 1 to increase with the height of the material pile. The tilt angle of the stacker is increased to keep the unloading point close to the height of the material pile, thus reducing dust.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
