A new structure of lifting hopper device

Abstract

This invention discloses a novel lifting hopper device, comprising a sliding support frame, a hopper, a discharge gate, a discharge bracket, a wire rope, and a hoisting mechanism. When the lifting hopper rises to discharge material, the pulleys at the ends of the baffles on both sides of the discharge gate contact the discharge brackets fixed on both sides of the sliding support frame. Through the lever-angle pushing principle, the guide inclined structure on the upper part of the discharge bracket causes the discharge gate to open upwards, allowing the material in the hopper to be smoothly discharged into the mixer. When the elevator finishes discharging and descends, the discharge gate closes downwards by its own weight, ensuring safety, reliability, and smooth operation. This novel lifting hopper device has a reasonable structure and advantages such as simple structure, convenient use, safety, reliability, and easy observation of the feeding situation, effectively solving the problem of poor performance of traditional lifting hoppers.

[0005] The hopper is mounted on a sliding support frame. A front fixed bracket is provided at the front end of the hopper, and a rear fixed bracket is provided at the rear end of the hopper. Upper pulleys are provided on both sides of the upper end of the front fixed bracket, and lower pulleys are provided on both sides of the lower end of the front fixed bracket. The upper pulleys and lower pulleys are slidably mounted in the U-shaped channel steel.

[0006] Two wire rope lugs are provided in the middle of the front fixed bracket, and the wire rope lugs are connected to the winch mechanism fixedly installed on the top of the sliding support frame through the wire rope; the rear fixed bracket has a first shaft hole on each side, and a discharge gate pin is provided on the first shaft hole; the lower ends of the plates on the left and right sides of the discharge port of the hopper have an arc-shaped structure cut with the center of the first shaft hole as the center, and the lower ends of the plates on the front and rear sides of the discharge port are horizontal structures connecting the lower ends of the left and right side plates;

[0007] The unloading gate includes an arc-shaped gate panel and a baffle; the baffle has a "<" shaped structure, one end of the baffle is provided with a control pulley, the other end of the baffle is fixedly set on both sides of the gate panel, and a second shaft hole is provided at the middle corner of the baffle for rotatable connection with the unloading gate pin; the inner arc surface of the gate panel is tightly fitted and sealed with the unloading port;

[0008] The unloading bracket has a trapezoidal frame structure. The unloading bracket is fixedly installed on the left and right sides of the sliding support frame. The upper part of the unloading bracket is provided with a guide slope. The guide slope slides against the control pulley on the unloading gate after contacting it.

[0009] Furthermore, the sliding support frame is welded from two U-shaped channel steels with opposite slots. The sliding support frame is fixedly mounted on the mixer and / or the ground by a bracket, and the angle of inclination of the sliding support frame to the horizontal plane is 60 degrees.

[0010] Furthermore, the hopper has lifting lug holes on both sides of its top.

[0011] Furthermore, the two baffles are provided with reinforcing ribs on the outer side.

[0012] Furthermore, it also includes a feed inlet slide plate, which is a rectangular plate structure set below the hopper that just covers the feed inlet of the mixer. At the four corners of the feed inlet slide plate, there are slide plate pulleys that are slidably connected to the sliding support frame. The lower end of the feed inlet slide plate abuts and limits the sliding support frame. The upper end of the feed inlet slide plate is symmetrically provided with two upward-facing hooks. After the hooks contact the pulley connecting shaft at the hopper, they can drive the feed inlet slide plate to rise as a whole and open the feed inlet of the mixer.

[0013] Furthermore, two wire rope lugs are provided at the middle position of the front-end fixed bracket, and the wire rope lugs are hinged to the front-end fixed bracket through a pivot.

[0014] The beneficial effects of this invention are as follows: A novel lifting hopper device is suitable for loading and unloading aggregates in a mixer. When the lifting hopper rises to unload, the pulleys at the ends of the baffles on both sides of the unloading gate contact the unloading brackets fixed on both sides of the sliding support frame. Through the lever angle pushing principle, the guide inclined structure on the upper part of the unloading bracket causes the unloading gate to open upwards, allowing the material in the hopper to be smoothly unloaded into the mixer. When the lifting machine finishes unloading and descends, the unloading gate closes downwards by its own weight, ensuring safety, reliability, and smooth operation. Simultaneously with the hopper's up-and-down movement, the feed inlet slide plate can move up and down, allowing the feed inlet slide plate to close the mixer feed inlet when no feeding is needed, preventing debris from entering. When feeding is required, it can open the mixer feed inlet as the hopper rises. Its structure is reasonable, simple, easy to use, safe, reliable, and allows for easy observation of the feeding situation, effectively solving the problem of poor performance of traditional lifting hoppers.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] like Figures 1 to 10 The novel lifting hopper device shown includes a sliding support frame 1, a hopper 4, a discharge gate 2, a discharge bracket 6, a wire rope 5, and a hoisting mechanism 7. The sliding support frame 1 is welded from two U-shaped channel steels with opposite grooves. Specifically, the two U-shaped channel steels are arranged with their grooves facing each other, and a fixed bracket is set between the two U-shaped channel steels. The fixed bracket is welded and fixed to the two U-shaped channel steels respectively. The sliding support frame 1 is also fixedly mounted on the mixer 10 and / or the ground at an angle by the bracket.

[0030] The hopper 4 is mounted on the sliding support frame 1. The front end of the hopper 4 is provided with a front fixed bracket 4-8, and the rear end of the hopper 4 is provided with a rear fixed bracket 4-7. The front fixed bracket 4-8 has upper pulleys 4-3 on both sides of its upper end and lower pulleys 4-1 on both sides of its lower end. The upper pulleys 4-3 and lower pulleys 4-1 are slidably mounted within the U-shaped channel steel, and the four pulleys mutually limit each other to prevent slippage out of the channel opening. In a possible embodiment, the openings of the two U-shaped channel steels can also face each other or both face upwards.

[0031] Two wire rope lugs 4-9 are provided at the middle of the front-end fixed bracket 4-8. The wire rope lugs 4-9 are connected to the winch mechanism 7 fixedly installed on the top of the sliding support frame 1 via wire ropes 5. The winch mechanism 7 can be, for example, a winch or other similar mechanism, which is existing technology and will not be described in detail. Using two wire ropes for lifting can effectively prevent the hopper 4 from suddenly sliding down and injuring people due to wire breakage, thus improving safety.

[0032] The rear fixed bracket 4-7 has a first shaft hole 4-2 on each side, and a discharge gate pin 3 is provided on the first shaft hole 4-2; the lower ends of the plates on the left and right sides of the discharge port 4-5 of the hopper 4 have an arc-shaped structure cut with the center of the first shaft hole 4-2 as the center, and the lower ends of the plates on the front and rear sides of the discharge port 4-5 are horizontal structures connecting the lower ends of the left and right side plates, that is, the lower end of the discharge port 4-5 is an arch-shaped structure.

[0033] The unloading gate 2 includes an arc-shaped gate panel 2-3 and a baffle 2-4. The baffle 2-4 has a "<" shaped structure. One end of the baffle 2-4 is provided with a control pulley 2-1, and the other end of the baffle 2-4 is fixedly set on both sides of the gate panel 2-3. The middle corner of the baffle 2-4 is provided with a second shaft hole 2-2 that is rotatably connected to the unloading gate pin 3. The inner arc surface of the gate panel 2-3 is tightly fitted and sealed with the unloading port 4-5. That is, the inner arc surface of the gate panel 2-3 is also centered on the center of the first shaft hole 4-2, and the radius is the same as the lower arc structure of the plates on the left and right sides of the unloading port 4-5. The width of the gate panel 2-3 is sufficient to cover the entire unloading port 4-5.

[0034] The unloading bracket 6 has a trapezoidal frame structure. The unloading bracket 6 is fixedly installed on the left and right sides of the sliding support frame 1. The upper part of the unloading bracket 6 is provided with a guide slope 6-1. The guide slope 6-1 slides against the control pulley 2-1 on the unloading gate 2 after contact. When the control pulley 2-1 slides upward, it drives the gate panel 2-3 to rise through the baffle 2-4 to open the unloading port 4-5. When the control pulley 2-1 slides downward, it drives the gate panel 2-3 to descend smoothly under the action of gravity to close the unloading port 4-5.

[0035] In one embodiment, the sliding support frame 1 is made of two U-shaped channel steel materials with opposite grooves welded together. The sliding support frame 1 is fixedly mounted on the mixer 10 and / or the ground by a bracket, and the angle of inclination of the sliding support frame 1 to the horizontal plane is 60 degrees.

[0036] In one embodiment, the top of the hopper 4 has lifting lugs 4-6 on both sides to facilitate the installation and disassembly of the hopper 4.

[0037] In one embodiment, the outer side of the two baffles 2-4 is provided with reinforcing ribs to increase mechanical strength.

[0038] In one embodiment, the system further includes a feed inlet slide plate 8, which is a rectangular plate structure located below the hopper 4 and covering the mixer feed inlet 9. The four corners of the feed inlet slide plate 8 are respectively equipped with slide plate pulleys 8-1 that are slidably connected to the sliding support frame 1. The lower end of the feed inlet slide plate 8 abuts against the sliding support frame 1 for limiting. The upper end of the feed inlet slide plate 8 is symmetrically provided with two upward-facing hooks 8-2. After the hooks 8-2 contact the pulley connecting shaft 4-4 at the hopper 4, they can drive the feed inlet slide plate 8 to rise as a whole and open the mixer feed inlet 9.

[0039] In one embodiment, two wire rope lugs 4-9 are provided at the middle position of the front-end fixed bracket 4-8, and the wire rope lugs 4-9 are hinged to the front-end fixed bracket 4-8 through a pivot.

[0040] This invention discloses a novel lifting hopper device with a reasonable structure, suitable for loading and unloading aggregates in a mixer. When the lifting hopper rises to unload, the pulleys at the ends of the baffles on both sides of the unloading gate contact the unloading brackets fixed on both sides of the sliding support frame. Through the lever angle pushing principle, the guide inclined structure on the upper part of the unloading bracket causes the unloading gate to open upwards, allowing the material in the hopper to be smoothly unloaded into the mixer. When the lifting machine finishes unloading and descends, the unloading gate closes downwards by its own weight, ensuring safety, reliability, and smooth operation. Simultaneously with the hopper's up-and-down movement, the feed inlet slide plate can also move up and down, allowing the feed inlet slide plate to close the mixer feed inlet when no feeding is needed, preventing debris from entering. When feeding is required, it can open the mixer feed inlet as the hopper rises. Its reasonable structure offers advantages such as simple design, ease of use, safety, reliability, and convenient observation of the feeding situation, effectively solving the problem of poor performance of traditional lifting hoppers.
