Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of belt conveyors, and in particular to a belt conveyor unloading system for abrasive and sticky materials and a control method thereof. Background Art
[0002] Belt conveyors use electric motors to drive the transmission drum to rotate, and use friction to drive the endless conveyor belt to operate continuously. They are widely used in industry, mining, agriculture, transportation and other fields to transport materials.
[0003] In belt conveyor unloading systems, although abrasion resistance or anti-clogging modifications can be implemented based on the characteristics of different materials to extend equipment life or ensure smooth unloading, these solutions generally only address the characteristics of a single material flow and cannot meet the actual needs of conveying multiple materials on a single belt conveyor. Since many applications require the simultaneous handling of both abrasive and sticky materials, traditional modification methods tend to prioritize abrasion resistance and address the unloading of sticky materials through regular manual poking operations. While this approach ensures smooth unloading to a certain extent, the frequency and complexity of manual inspections during operation greatly increase, resulting in low work efficiency. Furthermore, when renovating old production lines, space height restrictions are often encountered, making many traditional material dispensing equipment difficult to install. In particular, some modification solutions that require complex equipment such as tees become difficult to use within the existing installation constraints. Therefore, how to effectively handle both abrasive and sticky materials within the existing space conditions has become a current problem that needs to be solved. Therefore, it is necessary to propose a belt conveyor unloading system and control method for abrasive and sticky materials. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Example 1
[0035] Reference Figure 1-Figure 5 A belt conveyor unloading system for abrasive and sticky materials includes a belt conveyor head cover 1, an anti-blocking unloading component 8, and a wear-resistant unloading component 9. The anti-blocking unloading component 8 consists of a first steel pipe 2 with two bearings, multiple connecting plates 3, an anti-blocking unloading chute 4, an anti-blocking liner 5, a rotary joint 6, and an electro-hydraulic push rod 7. The wear-resistant unloading component 9 consists of a wear-resistant unloading chute 10 and a second steel pipe 11 with two bearings. The wear-resistant unloading chute 10 is composed of a flat bottom plate and two side baffles welded at a certain angle. The welding angle between the flat bottom plate and the baffle is an obtuse angle to prevent material from spilling. The baffle of the wear-resistant unloading chute 10 is away from the second steel pipe 1. 1. One side of the belt conveyor is beveled so that the chute can fit into the belt conveyor head cover 1 when it rotates. The width of the wear-resistant unloading chute 10 is the same at both ends. The wear-resistant unloading chute 10 is made of composite wear-resistant plate and fixed with angle steel. The wear-resistant layer faces the inside of the wear-resistant unloading chute 10. Holes are opened on both side plates of the belt conveyor head cover 1. Both ends of the second steel pipe 11 extend to the outside through the openings on the belt conveyor head cover 1. The two bearing outer rings with the second steel pipe 11 are respectively connected to the two side plates of the belt conveyor head cover 1. The steel pipe part with the second steel pipe 11 is welded to the wear-resistant unloading chute 10. The chute is slightly extended to completely cover the steel pipe to reduce the abrasion of the material flow on the steel pipe.
[0036] It should be noted that the anti-blocking discharge chute 4 is composed of an arc-shaped bottom plate and baffles on both sides welded at a certain angle. The welding angle of the arc-shaped bottom plate and the baffle is an obtuse angle to prevent material from being scattered. The widths of the two ends of the anti-blocking discharge chute 4 are different. The side close to multiple connecting plates 3 is the feeding end, and the side away from multiple connecting plates 3 is the discharging end. The width of the feeding end is greater than the width of the discharging end, which plays the role of gathering the material flow. The inner wall of the anti-blocking discharge chute 4 facing the incoming material is pasted with an anti-blocking lining plate 5 to ensure smooth discharge of sticky and wet materials. The present invention can control the material to flow in a more concentrated manner, and can make fuller use of the kinetic energy of the material to quickly discharge the material. The steel pipe portion of the first steel pipe 2 is connected to the inner ring of the bearing, and the steel pipe portion of the first steel pipe 2 is connected to multiple connecting plates The plates 3 are welded, the anti-blocking discharge chute 4 is welded to multiple connecting plates 3, and the rotary joint 6 is composed of two movable parts and a rotating part. The two movable parts can only rotate around a rotating axis. One movable part is welded to the anti-blocking discharge chute 4, and the other movable part is welded to the electro-hydraulic push rod 7. The electro-hydraulic push rod 7 is located outside the belt conveyor head cover 1. The piston rod of the electro-hydraulic push rod 7 extends to the inside through the opening on the belt conveyor head cover 1 and is welded to the rotary joint 6 and a movable part. The present invention can not only switch to the anti-blocking state, so that the sticky and wet materials can be discharged through the chute with the anti-blocking lining, ensuring smooth discharge of the sticky and wet materials, but also can switch to the wear-resistant state, so that the abrasive materials can be discharged through the chute made of composite wear-resistant plate, thereby extending the service life of the equipment.
[0037] In the present invention, when conveying sticky and wet materials, after the wear-resistant discharge chute is rotated to the left, the electro-hydraulic push rod is extended to lower the anti-blocking discharge chute 8, so that the sticky and wet materials are discharged through the chute with the anti-blocking lining. At the same time, the special chute shape can make the material flow at a higher speed and in a more concentrated manner, further reducing the possibility of blockage. When conveying abrasive materials, the electro-hydraulic push rod 7 contracts to drive the anti-blocking discharge chute 8 to lift, and then the wear-resistant discharge chute 10 is rotated to the right, so that the abrasive materials are discharged through the chute made of composite wear-resistant plates, thereby extending the service life of the equipment. The discharge areas of the two types of materials do not overlap. In the design process of subsequent chutes, more suitable chutes can be connected to different areas. The subsequent wear-resistant discharge chute can adopt a stepped design, and the subsequent anti-blocking discharge chute can be affixed with an anti-blocking liner on the inside and a vibration motor can be added on the side to prevent blockage.
[0038] The present invention also provides a control method for unloading abrasive and sticky materials from a shared belt conveyor, comprising the following steps:
[0039] S1: Material type identification, confirming the current conveying material type, i.e., sticky or abrasive, through sensors or manual input, and triggering corresponding control instructions;
[0040] S2: Chute switching preparation, sticky material: control the electro-hydraulic push rod 7 to extend, and at the same time rotate the wear-resistant discharge chute 10 to the left to disengage the working position; abrasive material: retract the electro-hydraulic push rod 7 to lift the anti-blocking discharge chute 8, and rotate the wear-resistant discharge chute 10 to the right working position;
[0041] S3: The chute status is locked, and the anti-blocking chute 4 or the wear-resistant chute 10 is verified to be in place through the limit switch or pressure sensor to ensure accurate mechanical positioning;
[0042] S4: Auxiliary function activated, sticky and wet materials: start the vibration motor of the anti-blocking liner 5 to enhance material fluidity; abrasive materials: turn off the vibration function and activate the stepped wear-resistant chute to reduce impact wear;
[0043] S5: Operation monitoring and adjustment, real-time monitoring of material flow rate and blocking signal, dynamic adjustment of electro-hydraulic push rod stroke or vibration frequency to optimize the pass rate;
[0044] S6: Switch to reset. After the material transportation is completed, reset all components to the initial position to prepare for the next operation. The present invention is based on the different unloading positions of the two types of materials, which is convenient for the design and production of subsequent chutes. It can also be completely controlled by electrical automation, reducing the workload of manual inspections, occupying less space, and can meet most technical transformation application scenarios.
[0045] Example 2
[0046] Reference Figure 1-Figure 5 , a belt conveyor unloading system for abrasive sticky materials, including a belt conveyor head cover 1, an anti-blocking unloading component 8, and a wear-resistant unloading component 9, wherein the anti-blocking unloading component 8 is composed of a first steel pipe 2 with two bearings, multiple connecting plates 3, an anti-blocking unloading chute 4, an anti-blocking liner 5, a rotary joint 6 and an electro-hydraulic push rod 7. The unloading chute 4 is composed of an arc-shaped bottom plate and two side baffles welded at an obtuse angle. The width of the two ends of the unloading chute 4 is different. The width of the feed end close to the multiple connecting plates 3 is greater than the width of the discharge end away from the multiple connecting plates 3, which plays a role in gathering the material flow. The inner wall of the unloading chute 4 facing the incoming material side is affixed with an anti-blocking liner 5 to ensure smooth unloading of sticky materials. The two ends of the steel pipe of the first steel pipe 2 with two bearings pass through the two side plates of the belt conveyor head cover 1 respectively. The upper opening extends to the outside, and the outer rings of the two bearings are respectively connected to the two side plates of the belt conveyor head cover 1, the inner ring of the bearing is connected to the steel pipe part, the steel pipe part is welded to multiple connecting plates 3, and multiple connecting plates 3 are welded to the anti-blocking discharge chute 4. The anti-blocking discharge chute 4 is connected to the electro-hydraulic push rod 7 through a rotary joint 6. The electro-hydraulic push rod 7 is located outside the belt conveyor head cover 1, and only the piston rod extends into the interior through the opening on the belt conveyor head cover 1 and is connected to the anti-blocking discharge chute 4. The whole set of anti-blocking discharge components can realize linear movement through the electro-hydraulic push rod 7, driving the anti-blocking discharge chute 4 to rotate around the first steel pipe 2 with two bearings. The present invention can switch to the anti-blocking state, so that the sticky and wet materials can be discharged through the chute with the anti-blocking lining, ensuring smooth discharge of the sticky and wet materials.
[0047] In particular, the wear-resistant unloading assembly 9 is composed of a wear-resistant unloading chute 10 and a second steel pipe 11 with two bearings. The wear-resistant unloading chute 10 is composed of a flat bottom plate and two side baffles welded at an obtuse angle. The baffle of the wear-resistant unloading chute 10 is cut away from the side of the second steel pipe 11 with two bearings so that it can fit the belt conveyor head cover 1 when it rotates. The width of the wear-resistant unloading chute 10 is the same at both ends. The manufacturing material is a composite wear-resistant plate fixed with angle steel, with the wear-resistant layer facing inward. The two ends of the steel pipe of the second steel pipe 11 with two bearings pass through the belt conveyor respectively. The openings on the two side plates of the head cover 1 extend to the outside, and the outer rings of the two bearings are respectively connected to the two side plates of the belt conveyor head cover 1, and the inner ring of the bearing is connected to the steel pipe part, and the steel pipe part is welded to the wear-resistant unloading chute 10. The chute is slightly extended during production to completely cover the steel pipe to reduce the abrasion of the material flow on the steel pipe. The whole set of wear-resistant unloading components can realize the wear-resistant unloading chute 10 to rotate around the second steel pipe 11 with two bearings. The present invention can switch to a wear-resistant state, so that abrasive materials can be discharged through the chute made of composite wear-resistant plates, thereby extending the service life of the equipment.
[0048] Working principle: When conveying sticky and wet materials, after the wear-resistant discharge chute is rotated to the left, the electro-hydraulic push rod is extended to lower the anti-blocking discharge chute 8, so that the sticky and wet materials are discharged through the chute with an anti-blocking lining. At the same time, the special chute shape allows the material to flow at a higher speed and in a more concentrated manner, further reducing the possibility of blockage. When conveying abrasive materials, the electro-hydraulic push rod 7 contracts to drive the anti-blocking discharge chute 8 to lift, and then the wear-resistant discharge chute 10 is rotated to the right, so that the abrasive materials are discharged through the chute made of composite wear-resistant plates, extending the service life of the equipment. The discharge areas of the two types of materials do not overlap. In the subsequent chute design process, more suitable chutes can be connected to different areas. The subsequent wear-resistant discharge chute can adopt a stepped design, and the subsequent anti-blocking discharge chute can be affixed with an anti-blocking liner inside and a vibration motor can be added on the side to prevent blockage.
[0049] The present invention also proposes a control method for unloading a shared belt conveyor for abrasive and sticky materials, comprising the following steps: S1: material type identification, confirming the type of the currently conveyed material, i.e., sticky or abrasive, through a sensor or manual input, and triggering a corresponding control instruction; S2: chute switching preparation, sticky and wet materials: controlling the electro-hydraulic push rod 7 to extend, while rotating the wear-resistant unloading chute 10 to the left to disengage from the working position; abrasive materials: retracting the electro-hydraulic push rod 7 to lift the anti-blocking unloading chute 8, and rotating the wear-resistant unloading chute 10 to the right working position; S3: chute state locking, through the limit The switch or pressure sensor verifies whether the anti-blocking chute 4 or the wear-resistant chute 10 is in place to ensure accurate mechanical positioning; S4: Auxiliary function activation, sticky and wet materials: start the vibration motor of the anti-blocking liner 5 to enhance material fluidity; abrasive materials: turn off the vibration function and enable the stepped wear-resistant chute to reduce impact wear; S5: Operation monitoring and adjustment, real-time monitoring of the discharge flow rate and blockage signal, dynamic adjustment of the electro-hydraulic push rod stroke or vibration frequency to optimize the pass rate; S6: Switch reset, after the material conveying is completed, reset all components to the initial position to prepare for the next operation.
