Description

Technical Field

[0001] This invention relates to the field of ship loader technology, specifically to a ship loader tail car, and also to a ship loader having the aforementioned tail car. Background Technology

[0002] A ship loader is a large bulk material handling machine used for loading ships at a bulk cargo terminal. It typically includes a boom conveyor, chute, tail car, and traveling mechanism. The tail car's function is to transfer material from the ground-based belt conveyor to the ship loader's belt conveyor, facilitating the transfer of material from the ground to the ship loader's interior. It also provides power for the ship loader's movement along the tracks at the dock's edge, enabling it to move flexibly according to the ship's position and loading / unloading requirements.

[0003] The structural design of the tail car needs to adapt to the working environment and operating conditions. Under different dock and ship berthing conditions, the tail car can ensure the stable operation of the ship loader through its own adjustments and support. However, the existing tail car structural design of ship loaders still has some shortcomings. Materials and equipment are dispersed on the belt conveyor through the hopper, and the contact points are relatively concentrated. The belt is subjected to greater impact, which can cause materials to spill and generate a lot of dust. This not only affects the normal operation of the equipment, but also pollutes the dock environment. Summary of the Invention

[0004] The primary objective of this invention is to overcome the shortcomings of the prior art and provide a loader tail car to solve the technical problem of uneven material distribution.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0006] A ship loader tail car, comprising:

[0007] The tail frame has a belt conveyor frame on its top surface, which supports and fixes a belt conveyor. The tail frame has support legs on its bottom surface, which are connected to wheels, which are connected to the output end of a walking motor.

[0008] A material guiding device includes a hopper, which is mounted on the feed end of the belt conveyor via a hopper frame. One end of a guide plate is hinged inside the hopper, and the guide plate is connected to the feed side of the belt conveyor. The other end of the guide plate is floatingly connected to the hopper frame via a shock-absorbing device.

[0009] Furthermore, a rotating frame is laterally rotatably arranged above the guide plate inside the hopper, and the rotating frame is arranged in a circumferential array with multiple feeding plates. The rotating frame passes through the hopper and is connected to the output end of the feeding motor.

[0010] Furthermore, a ceramic wear-resistant plate is provided on the side of the guide plate that contacts the material, and an inspection window is provided on the side wall of the hopper. An inspection door is hinged to the outside of the inspection window and is fixed to the outside of the hopper by a buckle.

[0011] Furthermore, a side guide plate extends upward from the side of the guide plate.

[0012] Furthermore, an inclined groove is formed on the inner side wall of the hopper, which is adapted to the rotation angle of the guide plate and limits its rotation when it reaches the lowest angle.

[0013] Furthermore, the feeding plate is arc-shaped, with the concave side of the arc facing in the opposite direction to the rotation of the rotating frame, and a number of screening teeth are densely arranged on the concave side of the arc.

[0014] Furthermore, the belt conveyor includes two sets of belts and belt rollers arranged at a certain angle, with a material transport trough formed between the two sets of belt rollers.

[0015] Furthermore, the tail frame is provided with a lifting seat from the outside of the two sets of belts and belt rollers. The lifting seat is connected to a side baffle by bolts. The side baffle is located on the upper surface of the belt and leaves a gap with the belt.

[0016] Furthermore, the outriggers and the wheels are symmetrically arranged on the left and right sides of the tail frame, and an oblique support rod is provided between the outriggers and the tail frame, while a transverse support rod is provided between the outriggers.

[0017] In an embodiment of this utility model, a ship loader is also provided, wherein the ship loader is equipped with the ship loader tail car of any of the above-mentioned embodiments.

[0018] The advantages and beneficial effects of this invention are as follows:

[0019] 1. The coordinated operation of the material guiding device and the belt conveyor enables efficient and stable material transport from the hopper to the belt conveyor. The hopper is equipped with a rotating frame and a feeding plate, which can buffer the material and distribute it evenly on the belt, preventing material accumulation and improving conveying efficiency.

[0020] 2. The inclined groove on the inner side wall of the hopper is matched with the rotation angle of the guide plate. When the guide plate rotates to the lowest angle, it can play a limiting role, ensuring that the guide plate moves within a reasonable range and preventing material conveying from being obstructed or equipment from being damaged due to excessive swinging of the guide plate.

[0021] 3. The arc-shaped design of the feeding plate and the densely arranged screening teeth on it can not only make the material evenly conveyed to the belt, but also screen the material to a certain extent, remove impurities or large particles that do not meet the requirements, and improve the quality of the loaded material.

[0030] Tail frame 1, belt conveyor frame 2 is provided on the top surface of tail frame 1, belt conveyor frame 2 supports and fixes belt conveyor 3, support legs 4 are provided below tail frame 1, support legs 4 are connected to wheels 5, wheels 5 are connected to the output end of walking motor;

[0031] The material guiding device includes a hopper 6, which is mounted on the feed end of the belt conveyor 3 via a hopper frame 7. A guide plate 8 is hinged inside the hopper 6 and connected to the feed side of the belt conveyor 3. The side of the guide plate 8 closest to the belt conveyor 3 is hinged to the hopper 6, and the other end of the guide plate 8 is floatingly connected to the hopper frame 7 via a shock-absorbing device 9. A rotating frame 10 is laterally rotatable above the guide plate 8 inside the hopper 6. Multiple feeding plates 11 are arranged in a circular array on the rotating frame 10, which passes through the hopper 6 and connects to the output end of the feeding motor. Side guide plates 16 extend upwards from the sides of the guide plate 8 to prevent material from entering the shock-absorbing device 9 from both sides of the guide plate 8. The shock-absorbing device 9 is preferably one of a hydraulic rod, a pneumatic rod, or a spring.

[0032] An inclined groove 17 is formed on the inner side wall of the hopper 6. The inclined groove 17 is adapted to the rotation angle of the guide plate 8 and forms a limit on it when it rotates to the lowest angle. The feeding plate 11 is arc-shaped, and the concave side of the arc is opposite to the rotation direction of the rotating frame 10. Several screening teeth 18 are also densely arranged on the concave side of the arc.

[0033] A ceramic wear-resistant plate 12 is provided on the side of the guide plate 8 that contacts the material. An inspection window 13 is provided on the side wall of the hopper 6. An inspection door 14 is hinged to the outside of the inspection window 13. The inspection door 14 is fixed to the outside of the hopper 6 by a buckle 15.

[0034] The belt conveyor 3 includes two sets of belts and belt rollers arranged at a certain angle, forming a material transport trough 19 between the two sets of belt rollers. A lifting seat 20 is provided on the tail frame 1 from the outside of the two sets of belts and belt rollers, and the lifting seat 20 is equipped with bolts 21 for adjusting the height of the side baffles 24. The side baffles 24 are located on the upper surface of the belts and have a gap between them.

[0035] Outriggers 4 and wheels 5 are symmetrically arranged on the left and right sides of the tail frame 1. An oblique support rod 22 is provided between the outriggers 4 and the tail frame 1, and a transverse support rod 23 is provided between the outriggers 4.

[0036] The working principle of this utility model is as follows: When material enters the guiding device through the hopper 6, the guide plate 8 inside the hopper 6 acts as a buffer and guide, reducing the impact of the material on the equipment. Side guide plates 16 extend upwards from the side of the guide plate 8, further guiding the material into the belt conveyor 3. The rotating frame 10 is driven by a feeding motor and is equipped with multiple arc-shaped feeding plates 11, with their concave side facing the opposite direction of rotation. The feeding plates 11 are also equipped with screening teeth 18, which can perform preliminary screening while feeding, helping to distribute the material more evenly on the belt.

The tilt angle of the belt conveyor 3 can be adjusted according to actual needs to adapt to the conveying requirements of different materials. The tail frame 1 is provided with a lifting seat 20 from the outside of the two sets of belts and belt rollers. The lifting seat 20 is connected to a side baffle 24. The side baffle 24 is set on the upper surface of the belt and leaves a gap with the belt. This can prevent material from overflowing the belt. At the same time, the height of the side baffle 24 can be changed by adjusting the bolts to avoid interfering with the belt operation.

[0037] The outriggers 4 are connected to the wheels 5, which are connected to the output of the travel motor. Driven by the travel motor, the tail car can move on the track, thus achieving flexible positioning of the ship loader. The outriggers 4 and wheels 5 are symmetrically arranged on the left and right sides of the tail car frame 1 to ensure the stability and balance of the tail car. An inclined support rod 22 is provided between the outriggers 4 and the tail car frame 1, and a transverse support rod 23 is provided between the outriggers 4. These support structures enhance the overall rigidity and stability of the tail car. The guide plate 8 is floatingly connected to the hopper frame 7 through a shock-absorbing device 9, which also plays a role in shock absorption and buffering, reducing vibration and noise during equipment operation. An inclined groove 17 is opened on the inner side wall of the hopper 6 to adapt to the rotation angle of the guide plate 8, preventing material from jamming the guide plate and forming a limit when the guide plate rotates to the lowest angle, ensuring that the guide plate moves within a predetermined range.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
