Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bucket wheel excavator technology, specifically relating to a material guiding and adjusting device for the tail car discharge hopper of a bucket wheel excavator. Background Technology
[0002] Bucket wheel excavators are highly efficient and continuous bulk material handling and conveying equipment used in large material yards such as ports, mines, and power plants. Due to their wide operating range, flexible operation, and low site requirements, they have become a commonly used stacking and reclaiming equipment. A hopper is typically installed at the head of the tail car. When the bucket wheel excavator is stacking material, the guide plates inside the hopper guide and change the direction of the material flow. By adjusting the falling position of the material flow, it is ultimately directed to fall onto the conveyor belt.
[0003] However, the existing hopper structure is a fixed structure. When the operating conditions of the bucket wheel excavator change, it is difficult to adapt to different discharge angles and flow rates. This can easily cause impacts on the conveyor belt below the hopper during the unloading process, leading to the problem of the lower conveyor belt running off-track. Utility Model Content

[0031] A fixing sleeve is engaged within the receiving space of the first fixing block.
[0032] Furthermore, the guide plate bracket is provided with several U-shaped grooves at equal intervals at the positions where it mates with the connecting shaft, for accommodating the connecting shaft.
[0033] Furthermore, the first connection component also includes:
[0034] The first reinforcing plate is fixed to the top of the first connecting seat and its side is fixed to the hopper;
[0035] The second reinforcing plate is disposed between the first connecting seat and the hopper, with one side connected to the first connecting seat and the other side connected to the hopper.
[0036] Furthermore, the through hole that mates with the second connecting rod in the discharge hopper is a rectangular hole, and the side length of the rectangular hole in the vertical direction is greater than the shaft diameter of the second connecting rod.

Specifically, guide plate supports are symmetrically arranged on the inner wall of the hopper, allowing the guide plate assembly to rotatably mount on the supports. A second connecting component is fixed to the surface of the guide plate assembly away from the material drop area. A first connecting component, collinear with the second connecting component, is fixed to the outer wall of the hopper. An adjusting component rotates through the first connecting component, with its end inside the hopper connecting to the second connecting component. This structural design allows the guide plate assembly to rotate during operation by rotating the adjusting component, thereby changing the angle between the guide plate assembly and the inner wall of the hopper. This addresses the limitation of existing baffle plates in adjusting angle, preventing impact on the conveyor belt below the hopper during unloading and thus avoiding belt misalignment and improving operational efficiency.

[0050] It should be noted that the guide plate assembly 4 includes: a guide plate 40; upright plates 44 are respectively arranged on both sides of the guide plate 40 in the vertical direction, and symmetrical connecting holes are arranged on the outer side, the position of the connecting holes corresponding to the position of the guide plate bracket 5; the two ends of the fixed shaft 41 are respectively connected to the upright plate 44; one end of the connecting shaft 43 is arranged in the connecting hole of the upright plate 44, and the other end is rotatably connected to the guide plate bracket 5;
[0051] The guide plate bracket 5 and the guide plate assembly 4 are provided with three U-shaped grooves at equal intervals at the position of rotational engagement. The connecting shaft 43 can select one of the U-shaped grooves for connection according to the actual situation.
[0052] Specifically, when an external force pushes the guide plate 40, the guide plate 40 can rotate around the connecting shaft 43;
[0053] The second connecting component 3 is connected to the surface of the guide plate assembly 4 away from the material falling area;
[0054] It should be noted that the second connecting component 3 includes: a second connecting seat 33, a second fixing block 31, a first fixing block 30, and a fixing sleeve 32;
[0055] The second connecting seat 33 is a U-shaped seat, and its base is fixed on the surface of the guide plate 40 away from the material falling area.
[0056] The second fixing block 31 is fixed to the second connecting seat 33 by bolts;
[0057] The first fixing block 30 is a U-shaped block, and its end is fixed to the surface of the second fixing block 31 away from the guide plate 40;
[0058] The fixing sleeve 32 is snapped into the U-shaped receiving space of the first fixing block 30;
[0059] The first connecting component 2 is connected to the outer wall of the hopper 6 and is positioned opposite to the second connecting component 3;
[0060] It should be noted that the first connecting component 2 includes: a first connecting base 22, a connecting plate 21, and a connecting block 20;

[0064] It should be noted that the adjustment assembly 1 includes: a second connecting rod 12, a first connecting rod 11, and a handwheel 10;
[0065] The second connecting rod 12 is threaded at the position where it mates with the through hole of the connecting block 20;

[0067] Handwheel 10 is connected to the other end of the first connecting rod 11;
[0068] The second connecting rod 12 is divided into two parts: the part inside the fixed sleeve 32 is fixed to the fixed sleeve 32, and the remaining part is rotatably connected to the part in the fixed sleeve.
[0069] Specifically, rotating the handwheel 10 causes the rotatable parts of the first connecting rod 11 and the second connecting rod 12 to rotate, and through the thread provided inside the connecting block 20, it makes the connecting rod 12 move back and forth along the central axis of the connecting rod 12, thereby pushing the guide plate 40 to adjust its angle.
[0070] It should be noted that the through hole that mates with the hopper 6 on the second connecting rod 12 is a rectangular hole, and the side length of the rectangular hole in the vertical direction is greater than the diameter of the shaft of the second connecting rod 12.
[0071] Specifically, in order to ensure that the guide plate can be adjusted at an angle of 40° and rotate along the axis, the axial direction of the second connecting rod 12 can be changed by the rotating shafts on both sides of the connecting block 20.
[0072] In this embodiment, the first connecting component 2 further includes: a first reinforcing plate 23 and a second reinforcing plate 24;

[0074] The second reinforcing plate 24 is disposed between the first connecting seat 22 and the discharge hopper 6, with one side connected to the first connecting seat 22 and the other side connected to the discharge hopper 6.
[0075] In this embodiment, the surface of the guide plate 40 near the material falling area is provided with a groove, and the groove accommodates the liner plate 42.
[0076] In this embodiment, the fixing sleeve 32 is provided with a pin hole in the radial direction relative to the second connecting rod 12, and the second connecting rod 12 and the fixing sleeve 32 are fixed together with the pin shaft.
[0077] It should be noted that the conveyor belt machine mentioned in the instruction manual, located at the bottom of the hopper, is existing technology and will not be discussed in detail here.
[0078] Installation process:
[0079] First, based on the actual material feeding conditions, select a suitable U-shaped groove on the guide plate bracket 5, and mount the guide plate 40 in the U-shaped groove via the connecting shaft 43. Second, secure the fixing sleeve 32 inside the first fixing block 30, insert the second connecting rod 12 through the through hole of the connecting block 20, and then the second connecting rod 12 enters the hopper through the rectangular hole in the feeding hopper 6, finally reaching the outside of the fixing sleeve 32. At this point, rotate the handwheel 10 of the first connecting rod 11 to engage the threaded wall of the second connecting rod 12 with the thread of the connecting block 20. Simultaneously, the end of the second connecting rod 12 is fitted into the fixing sleeve 32, and after fitting, the pin is inserted into the pin hole of the fixing sleeve 32, thus fixing the second connecting rod 12 and the fixing sleeve 32, completing the installation.
[0080] Working principle:
[0081] The operator turns the handwheel 10, transmitting the rotational force to the second connecting rod 12 via the first connecting rod 11. Since the second connecting rod 12 is threadedly engaged with the connecting block 20 of the first connecting assembly 2, when the second connecting rod 12 rotates, the threaded engagement converts the rotational motion into linear motion, causing the second connecting rod 12 to extend or retract along its own axis, i.e., to move inward or outward from the hopper 6. Simultaneously, as the guide plate 40 rotates around the connecting shaft 43, the position of the second connecting assembly 3, fixed to the guide plate 40, swings with the angle of the guide plate 40. At this time, the connecting block 20 rotates flexibly with the connecting plate 21 via the rotating shafts on both sides, adjusting its posture according to the angle of the second connecting rod 12, ensuring smooth threaded transmission. The rectangular hole on the hopper 6 provides vertical space for the second connecting rod 12, preventing interference with the hopper 6 wall during movement. Finally, when the guide plate 40 reaches the designated angle, it stops rotating, and the threaded action of the connecting block 20 keeps the entire structure stationary.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
