Technical Field

[0001] This utility model relates to the technical field of unloading devices, specifically an equal-division unloading device for belt conveyors. Background Technology

[0002] As a core piece of machinery widely used in industries such as grain and oil, chemicals, ports, coal, and building materials, the unloader plays a crucial role in the material transfer process of belt conveyors. In actual production, depending on different process requirements, it is often necessary to accurately and equally unload the material on the belt into multiple silos or furnace openings.

[0003] However, existing traditional plow-type unloaders cannot flexibly adjust the unloading position and material distribution ratio according to actual needs. They are also difficult to change the material distribution structure and the distance between the belt edge to divide the material according to a preset ratio. This results in the inability to meet the quantitative feeding requirements of different silos or furnace openings, which limits the application of belt conveyors in the material distribution process and affects production efficiency and material utilization. Utility Model Content

The guide plate forms a 135-degree angle with the material distribution plate, and the guide plate is parallel to the arrangement of the gantry frame.

[0008] Furthermore, the right-angled tripod includes a connecting long arm and a connecting short arm that are rotatably connected to the inner sides of the gantry frame, a connecting horizontal arm located between the connecting long arm and the connecting short arm, and a reinforcing rod connected to the middle of one side of the connecting horizontal arm. The reinforcing rod is located between the connecting long arm and the connecting short arm.

[0019] Please see Figure 1-3 A method for equal-division unloading of a belt conveyor includes two parallel channel steels 1, a gantry frame 2 located at one end of the upper side of the two channel steels 1, a straight electro-hydraulic actuator 3 rotatably connected to the middle of the upper side of the gantry frame 2, a right-angled triangular frame 4 rotatably connected to the output end of the straight electro-hydraulic actuator 3, a movable adjustment mechanism 5 connected to the inclined surface of the right-angled triangular frame 4, and an L-shaped plow blade 6 connected to the lower side of the movable adjustment mechanism 5. The L-shaped plow blade 6 can be moved horizontally along its length direction by the movable adjustment mechanism 5. The right-angled triangular frame 4 is rotatably connected to the inner two sides of the gantry frame 2.

[0020] The movable adjustment mechanism 5 includes an adjustment housing 22, a strip-shaped opening 23 on the lower side of the adjustment housing 22 and extending through both ends, a lead screw 24 rotatably connected to the adjustment housing 22 via bearings, a handwheel 26 connected to one end of the lead screw 24 and located on the outside of the adjustment housing 22, two threaded sleeves 27 threadedly engaged with the lead screw 24 and spaced apart, and a connecting plate 25 connected to the lower side of the two threaded sleeves 27. One end of the connecting plate 25 passes through the strip-shaped opening 23 and extends to the lower part of the adjustment housing 22.

[0021] The L-shaped plow blade 6 includes a distribution plate 29 connected to the lower side of the connecting plate 25 and a guide plate 28 connected to one end of the distribution plate 29. The guide plate 28 forms a 135-degree angle with the distribution plate 29 and is arranged parallel to the gantry frame 2. This 135-degree angle design allows the material to be smoothly guided from the distribution plate 29 to the guide plate 28. The distribution plate 29 initially divides the material on the conveyor belt, and then, guided by the angle, the material flows to the guide plate 28, achieving a diversion process. This helps to divide the material according to a preset ratio, meeting the quantitative feeding requirements of different silos or furnace openings. The guide plate 28, arranged parallel to the gantry frame 2, ensures that the material, after being diverted, can enter the corresponding silo or furnace opening along a specific direction. This parallel arrangement makes the material guiding path more stable and predictable, reducing material deviation and scattering during the conveying process, and further improving the device's equal-division unloading capacity.

[0022] The right-angled tripod 4 includes a connecting long arm 12 and a connecting short arm 10 rotatably connected to the inner sides of the gantry frame 2, a connecting cross arm 11 welded between the connecting long arm 12 and the connecting short arm 10, and a reinforcing rod 9 welded to the middle of one side of the connecting cross arm 11. The reinforcing rod 9 is located between the connecting long arm 12 and the connecting short arm 10. The output end of the straight electro-hydraulic actuator 3 is rotatably connected to the upper side of the reinforcing rod 9. One end of the connecting long arm 12, the connecting short arm 10, and the reinforcing rod 9 are all connected to one side of the adjusting housing 22. A mounting bracket 8 is provided between the two channel steels 1. A leak-proof material assembly 7 is rotatably connected to the upper side of the mounting bracket 8. One end of the leak-proof material assembly 7 is rotatably connected to a linkage mechanism, which is connected to the connecting long arm 12 and the connecting short arm 10. The linkage mechanism includes an L-shaped transmission plate 21 connected to the connecting long arm 12 and the connecting short arm 10, a transmission rod 20 connected between the two L-shaped transmission plates 21, and two transmission plates 19 connected to the transmission rod 20 and spaced apart.

[0023] The anti-leakage component 7 includes a frame 16 and multiple idlers 17 rotatably connected within the frame 16 and spaced apart. One end of each of the two transmission plates 19 is rotatably connected to the two sides of the frame 16. The multiple spaced idlers 17 adhere to the belt surface of the belt conveyor, rising and tightening the belt under the linkage of the right-angled triangle 4, eliminating the gap when the belt contacts the L-shaped plow blade 6, preventing material leakage from the gap between the belt and the L-shaped plow blade 6, avoiding material spillage and waste, and reducing cleaning and maintenance costs. Simultaneously, the idlers 17 support and guide the belt, reducing belt vibration and deviation during operation. During unloading, uneven belt force can easily lead to belt deviation, but the idlers 17 can maintain stable belt operation through uniform support force, ensuring continuous and effective contact between the L-shaped plow blade 6 and the belt, improving the accuracy and stability of equal-division unloading. Furthermore, the idler roller 17 is rotatably connected to the frame 16, and can rotate synchronously with the belt during operation, converting the sliding friction between the belt and the idler roller 17 into rolling friction, reducing the belt running resistance. This not only reduces belt wear but also extends the belt's service life.

[0024] The mounting frame 8 includes two connecting crossbars 13 spaced apart between two channel steels 1, two mounting crossbars 14 spaced apart between the two connecting crossbars 13, two mounting seats 15 spaced apart on the upper side of the mounting crossbars 14, and support plates 18 rotatably connected to the mounting seats 15. One end of the four support plates 18 is rotatably connected to both sides of the frame 16.

[0025] Working Process and Principle: Multiple units of this device are arranged at intervals along the belt conveyor and fixed to the conveyor's intermediate frame via channel steel 1 and mounting frame 8. After installation, the workshop control cabinet activates the straight electro-hydraulic actuator 3. When the actuator extends, it drives the right-angled triangular frame 4 to descend, thereby causing the adjusting housing 22 and the L-shaped plow blade 6 to move down synchronously until the L-shaped plow blade 6 is in close contact with the belt surface. At the same time, the connecting long arm 12 and connecting short arm 10 of the right-angled triangular frame 4, in conjunction with the L-shaped transmission plate 21, transmission plate 19, and support plate 18, drive the frame 16 to rise, causing multiple idler rollers 17 to tighten the belt and prevent material leakage during unloading. When adjusting the unloading amount as needed, the operator turns the handwheel 26, which drives the lead screw 24 to rotate, causing the two threaded sleeves 27 to move along the lead screw 24, thereby pushing the L-shaped plow blade 6 to slide in the belt width direction, changing the distance between the material distribution plate 29 and the belt edge.

[0026] This device allows for easy adjustment of the horizontal position of the L-shaped plow blade 6 in the width direction of the belt according to actual needs, changing the distance between the material distribution plate 29 and the edge of the belt, thereby dividing the material according to a preset ratio. This enables the device to meet the quantitative feeding needs of different silos or furnace openings, expanding the application scenarios of belt conveyors in the material distribution process and improving the material distribution efficiency and utilization rate of belt conveyors.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
