Description

Technical Field

[0001] The present invention relates to the technical field of bulk material loading and unloading, and in particular to a pitching boom belt conveyor system of a ship loader. Background Art

[0002] Ship loaders are critical equipment for bulk cargo handling at ports. Their boom conveyors are responsible for transferring materials from the landside to the ship's hold. The chute, a key component at the conveyor's material transfer point, is installed beneath the boom conveyor's incoming hopper. Its performance directly impacts the equipment's operating efficiency, material loss, dust pollution, and maintenance costs. During bulk cargo handling, materials ejected from the incoming hopper must be effectively received and directed by the chute, allowing them to be smoothly transferred to the boom conveyor below.

[0003] In traditional material guide troughs, the arm of the ship loader needs to frequently pitch, extend, and rotate during operation to accommodate the loading needs of different ship types and cabins. This change in arm posture causes the material guide trough to tilt, dynamically changing its relative position and angle with the incoming material hopper above. Existing fixed or semi-fixed material guide troughs often struggle to fully adapt to this continuously changing relative position relationship, and gaps can easily form at the interface, leading to material escape and spillage. During material transportation, bulk materials are often mixed with sharp objects such as stones, which often impact the belt below at high speeds, causing the belt to deviate or be damaged. During the operation of the conveyor belt, the rubber skirt is used to prevent material spillage and guide material flow. Therefore, there is significant friction between the material and the rubber skirt, and between the conveyor belt and the rubber skirt, resulting in wear and tear, requiring frequent replacement of the rubber skirt. Summary of the Invention

[0004] In order to solve the problems of the existing material guide chute easily leaking materials when the boom is pitching, the belt running off track, the material having excessive impact on the belt, and the need for frequent replacement of rubber skirts, etc., the present invention provides a pitching boom belt conveyor system for a ship loader.

[0005] The technical solutions for achieving the purpose of the present invention are:

[0006] A luffing arm belt conveyor system for a ship loader, characterized by comprising:

[0007] Arm for fixing the guide trough and arm belt conveyor;

[0008] The guide trough fixed on the boom is used to receive and convey materials, including a guide trough body, an upper shell body provided at the upper end of the guide trough body and having an arched structure, a sliding cover plate that slides with the upper shell body and can adaptively slide along the arc surface of the upper shell body when the boom pitch angle changes and is provided with an opening for docking with the incoming material hopper, the incoming material hopper fixed on the sliding cover plate, movable baffles provided on the left and right sides of the guide trough body to guide the material to align with the center of the belt of the boom conveyor, and an adjustment device for controlling the inclination angle of the movable baffle;

[0009] The arm belt conveyor fixed on the arm and located below the material guide trough is used to transport materials;

[0010] The material guide trough body is surrounded by skirt plates for preventing material leakage and guiding the flow of material. The skirt plates are connected to the material guide trough body by a skirt plate clamping device with a quick-release structure.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] (1) The present invention avoids the problem of poor sealing effect of the rubber sealing plate in the prior art when the arm is pitched at a large angle. The present invention provides a sliding cover plate with an arc structure in the material guide trough to ensure that the material hopper can closely cooperate with the material guide trough to form a sealed environment when the arm is pitching, thereby preventing material from escaping.

[0013] (2) The present invention adjusts the telescopic length of the screw by a hand wheel and controls the movable baffle to rotate around the pin shaft to a certain angle, so as to reduce the impact force of the material on the belt below. At the same time, it can control the flow direction of the material so that its flow direction tends to the center line of the belt, so that the belt is evenly stressed and has a certain effect of preventing the belt from running off.

[0014] (3) The present invention utilizes the lever principle and can clamp the rubber skirt by pressing down the card plate. When the rubber skirt needs to be replaced, it is only necessary to loosen the card plate and the rubber skirt will be separated from the material guide trough, thereby achieving the effect of easily replacing the rubber skirt.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Combine Figures 1 to 3 The present invention relates to a pitching arm belt conveyor system for a ship loader, comprising: a material hopper 1, a material guide trough, an arm belt conveyor 3, and an arm 4; the material guide trough comprises: a material guide trough body 2, an upper shell 5, a sliding cover plate 6, a movable baffle 7, an adjustment device 8, a support frame 9, a skirt clamping device 10, and the like. The upper end of the material guide trough body 2 is provided with an upper shell 5, the top of the upper shell 5 adopts an arc-shaped structure, and the sliding cover plate 6 is covered on the arc top of the upper shell through a matching curvature surface at its bottom; Figure 2 Taking the working condition of the arm 4 being tilted upward as an example, the position of the incoming funnel 1 is fixed. When the arm 4 is tilted upward, the guide trough body 2 will be driven to tilt relative to the incoming funnel 1. In order to ensure the sealing of the guide trough body 2 and the incoming funnel 1 under this working condition, the middle opening of the sliding cover 6 is fixed to the discharge port of the incoming funnel 1. The side of the sliding cover 6 is an L-shaped vertical edge structure that is embedded in the inner side of the upper shell 5 to form a sliding pair, so that the sliding cover 6 can adaptively slide along the arc surface when the tilt angle of the arm 4 changes, thereby ensuring the sealing of the guide trough body 2 and the incoming funnel 1 when it slides relative to the arm 4 when it is tilted upward.

[0022] Combine Figure 4 , the adjusting device 8 is arranged inside the guide trough support frame 9, and includes a handwheel 14, a screw 15, a pin 12 and a cotter pin 13; the support frame 9 is used to support the guide trough body 2, and its legs are welded to the arm 4 to fix the guide trough 2 on the arm 4, and a handwheel 14 is provided. The handwheel 14 is fixed to the end of the screw 15 by a key connection, and the screw 15 passes through the side wall of the guide trough body 2, and its end cooperates with the movable baffle 7 located in the guide trough body 2; the movable baffle 7 is located on the left and right sides of the guide trough body 2, the surface is covered with a wear-resistant layer, and is hinged to the support frame 9 through the pin 12, and It is axially locked by a cotter pin 13; when the material is ejected from the incoming funnel 1, the hand wheel 14 is symmetrically adjusted to control the angle of the movable baffle 7 to ensure that the material can fall in line with the belt center line of the arm belt conveyor 3 below the guide trough body 2. At the same time, due to the obstruction of the movable baffle 7, the impact of the material on the belt and the side plates of the guide trough can be reduced; the arm belt conveyor 3 is installed inside the arm 4, including a belt located in the middle position and guide troughs located on both sides of the belt. The belt transports the material falling from the guide trough body 2 to the end of the arm 4 along the length direction of the arm 4, and the belt of the arm belt conveyor 3 coincides with the installation center line of the guide trough 2.

[0023] Combine Figure 5The guide trough body 2 is provided with rubber skirts 11 around it, and each rubber skirt 11 is connected to the guide trough body 2 through a plurality of skirt clamping devices 10. The skirt clamping devices 10 are arranged on the outside of the guide trough 2 and are used to fix the rubber skirts 11 on the guide trough body 2, including a bracket 17, a clamping plate 18, a through rod 19, a round steel 20 and an angle steel 21; the rubber skirts 11 are fixed to the guide trough body 2 around the discharge port by the skirt clamping devices 10, and are used to seal the lower end of the guide trough body 2 and restrict the flow of materials; The fixed end of the bracket 17 is welded to the side plate 16 of the guide trough body 2, the movable end is pressed on the angle steel 21, and the middle opening is passed through by the through rod 19; one end of the through rod 19 is fixed to the side plate 16 of the guide trough body 2, and the opening at the other end is passed through by the clamping plate 18; the insertion end of the clamping plate 18 is designed to be an inverted trapezoidal cross-section, the lower end of which is inserted into the opening at the other end of the through rod 19, and the side is pressed on the movable end of the bracket 17; the round steel 20 and the angle steel 21 are welded into a whole, the round steel 20 is located on the inner side of the bracket 17 and suspended on the through rod 19, and the angle steel 21 is in contact with the rubber skirt 11.

[0024] The specific principles of the present invention are as follows:

[0025] Since the incoming hopper 1 always guides the materials vertically downward, when the ship loader arm 4 pitches, the guide chute 2 will also swing accordingly. The opening of the sliding cover plate 6 is welded to the discharge port of the incoming hopper 1. The side of the sliding cover plate 6 has an L-shaped vertical edge structure and is embedded with the inner side of the upper shell 5 to form a sliding pair. The sliding cover plate 6 can adaptively slide along the arc surface when the pitch angle of the arm 4 changes, thereby ensuring the sealing of the guide chute 2 and the incoming hopper 1 when the arm 4 pitches and slides relative to each other;

[0026] When the device needs to be adjusted to divert material flow, rotating the handwheel 14 drives the screw 15 to move axially, pushing the movable baffle 7 to pivot around the pin 12, achieving continuous adjustment of its inclination angle. By controlling the opening of the baffle, the material flow can be accurately guided to fall into the center of the belt below, while effectively attenuating the impact energy of the material.

[0027] When the rubber skirt needs to be locked, the clamping plate 18 is pressed down. Its inverted trapezoidal structure and the slot of the through rod 19 form a lever fulcrum, forcing the movable end of the bracket 17 to move toward the side plate 16 of the guide trough body 2, pressing the angle steel 21 against the surface of the rubber skirt 11. At the same time, the round steel 20 provides a suspension support force to achieve uniform sealing and fixation of the rubber skirt 11. During the operation of the boom belt conveyor 3, the rubber skirt 11 is used to prevent material leakage and guide the flow of material. Therefore, there is a large friction between the material and the rubber skirt 11, and between the belt and the rubber skirt 11, which leads to wear and tear and requires frequent replacement of the rubber skirt 11. When the rubber skirt 11 needs to be replaced, it is only necessary to loosen the clamping plate 18, and the rubber skirt 11 will automatically fall off, so that the skirt can be quickly disassembled and assembled without bolts.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above examples, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technologies of the embodiments of the present invention.
