Description

Technical Field

[0001] This utility model belongs to the field of material leveling technology, and in particular relates to a material leveling device with adjustable leveling height. Background Technology

[0002] When train carriages or containers are loaded using belt conveyors, the material top is usually a self-igniting pile, which neither effectively utilizes the carriage volume nor prevents spillage. Therefore, in the field of material handling, leveling the material after loading it into the carriage is a common and important task. Traditional leveling methods have many drawbacks. For example, some existing leveling devices often have a fixed leveling height, making it difficult to adapt to the leveling requirements of materials of different heights. When encountering carriages with high or low material loading heights, effective leveling cannot be achieved, resulting in uneven distribution of material within the carriage. This not only fails to fully utilize the carriage volume but may also affect the stability of transportation.

[0003] There are two common methods for leveling materials: manual leveling and mechanical leveling. Manual leveling is inefficient and labor-intensive, and will gradually disappear. Common mechanical leveling methods include fixed scraper levelers and lifting auger levelers. Fixed scraper levelers use scrapers with a triangular projection, resulting in large dead angles and poor leveling effect. Lifting auger levelers use a single-stage lifting adjustment to control the height of the auger, which cannot adapt to the varying heights of truck beds and containers. Furthermore, the high-speed rotation of the auger mechanism requires a large safety margin between the auger and the side walls of the truck bed or container, making it difficult to control the height of the material on both sides during leveling.

[0004] In summary, existing material leveling devices have significant shortcomings in terms of adaptability to material leveling height, carriage width, and prevention of material spillage. There is an urgent need for a new type of material leveling device that can overcome these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a leveling device with adjustable leveling height to solve the technical problems mentioned in the background art. By utilizing the advantage of adjustable leveling height, it can adapt to leveling materials in carriages of various heights and widths, effectively utilizing the carriage volume while preventing spillage.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A material leveling device with adjustable material leveling height includes a fixed seat mounted on a gantry crane beam. The fixed seat is equipped with a telescopic frame that can extend and retract vertically. A material leveling scraper assembly is provided at the bottom free end of the telescopic frame. The material leveling scraper assembly includes a first scraper and a second scraper arranged side by side along the scraping direction. Multiple first scrapers are arranged along the length direction on the scraping surface of the first scraper, and multiple second scrapers are arranged along the length direction on the scraping surface of the second scraper. The first scraper, first scraper, second scraper, and second scraper cooperate to perform multiple material turning and leveling operations.

[0007] To further optimize this utility model, the following technical solutions may be preferred:

[0008] Preferably, the telescopic frame includes an outer frame and an inner frame that are nested together. The inner frame has multiple stages. A hydraulic cylinder connects the outer frame and the inner frame. A guide mechanism is also provided between the outer frame and the inner frame. The guide mechanism includes guide rails on both sides of the inner frame. The outer frame has slots that cooperate with the guide rails. A guide wheel is rotatably installed in the slot. The guide wheel serves to guide, flexibly extend and retract, and limit excessive shaking and swaying of the frame.

[0009] Preferably, the inner frame is provided with multiple levels, and a hydraulic cylinder is provided between two adjacent levels of the inner frame. The more levels of the telescopic frame, the larger its telescopic working range, and the better it can adapt to the flat material needs of various heights.

[0010] Preferably, the positions of the first scraper and the second scraper are staggered.

[0011] Preferably, both the first and second scrapers are plow-shaped scrapers. The plow tip of the plow-shaped scraper has low resistance to material insertion, and the working surface of the scraper is a plow-shaped curved surface, which can make the material quickly roll and spread to both sides.

[0012] Preferably, elastic baffles are provided at both ends of the inner side of the second scraper. The free end of the elastic baffle extends outward from the end of the second scraper. The elastic baffles make elastic contact with both sides of the material box, which can ensure that the material is leveled on both sides and that the material box is safe during leveling.

[0013] The adjustable material leveling device of this utility model has the following advantages:

[0014] (1) High adaptability: Due to the telescopic frame that can extend and retract vertically on the fixed base, the leveling device can flexibly adjust the leveling height according to the loading height of the material. Whether the material is loaded at a high height or a relatively low height, it can achieve precise and effective leveling, ensuring that the material is evenly distributed in the carriage, making full use of the carriage volume, improving transportation stability, and avoiding transportation safety hazards caused by uneven material distribution.

[0015] (2) Comprehensive and uniform leveling effect: The leveling scraper assembly includes a first scraper and a second scraper arranged side by side along the scraping direction. The first scraper is equipped with multiple first scrapers, and the second scraper is equipped with multiple second scrapers. Working together, they can perform multiple turning and leveling operations on materials in carriages of different widths. This unique structural design greatly improves the comprehensiveness and uniformity of leveling, solving the problem that traditional single scrapers cannot fully cover materials and have poor leveling effects.

[0016] (3) Reduce material spillage: By using the coordinated operation of the first scraper, the first scraper blade, the second scraper, and the second scraper blade to repeatedly turn and level the material, compared to the traditional single scraper leveling method, the movement of the material can be controlled more effectively, reducing the spillage of material during the leveling process. This not only avoids material waste and reduces production costs, but also maintains a clean working environment and reduces the cleaning work and environmental pollution caused by material spillage.

[0017] (4) Wide range of applicable materials: The device's multiple turning and leveling design enables it to perform well in leveling materials with high viscosity or uneven particle size. The combination of different scrapers and scrapers can better handle complex material characteristics, meet the leveling needs of various materials in actual production and transportation, and has wide applicability.

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a material leveling device with adjustable material leveling height.

[0030] like Figure 1-4As shown, a material leveling device with adjustable leveling height includes a fixed base 1 installed on a gantry crane beam. The fixed base is connected to the gantry crane beam by bolts. A telescopic frame 2 capable of vertical extension and retraction is installed on the fixed base. A material leveling scraper assembly 3 is installed at the free end of the bottom of the telescopic frame. The material leveling scraper assembly 3 includes a first scraper 4 and a second scraper 5 arranged side by side along the scraping direction. Multiple first scrapers 6 are installed along the length direction on the scraping surface of the first scraper, and multiple second scrapers 7 are installed along the length direction on the scraping surface of the second scraper. The second scrapers are located in the rear row near the fixed base, and the first scrapers are located in the front row. The first scraper, first scraper, second scraper, and second scraper work together to perform multiple material turning and leveling operations. The specific principle is that the material leveling scraper has a structure of two layers of scrapers and two layers of scrapers. The scrapers are plow-shaped, and each layer of scrapers is in a straight line. This linear arrangement of scrapers can be moved to the extreme positions at both ends of the carriage, ensuring no dead corners are left when leveling the material. The leveling scraper flattens the raised ridges after the material is separated by the scrapers. The second scraper (front leveling scraper) follows the second scraper (front scraper) and flattens the raised ridges of material after the scrapers. The first scraper (rear scraper) and the second scraper (front scraper) are staggered to continue scraping and separating the material. The first scraper (rear leveling scraper) flattens the raised ridges of material again after the scrapers, making the surface of the material even flatter.

[0031] The telescopic frame includes an outer frame 9 and an inner frame 10 that are nested together. The inner frame 10 is equipped with multiple stages. A hydraulic cylinder 11 connects the outer frame and the inner frame. A guide mechanism is also installed between the outer frame and the inner frame. The guide mechanism includes guide rails 12 installed on both sides of the inner frame. A slot 13 that mates with the guide rail is installed on the outer frame. A guide wheel 14 is rotatably installed in the slot. The guide wheel plays the role of guiding, flexibly extending and retracting, and limiting excessive shaking and swaying of the frame.

[0032] As a preferred embodiment, the inner frame 10 is installed in multiple stages, with a hydraulic cylinder installed between adjacent stages of the inner frame. The more stages of the telescopic frame, the larger its telescopic working range, and the better it can adapt to the needs of flat materials of various heights. Taking this embodiment as an example, it is a three-stage telescopic system, equipped with three hydraulic cylinders for telescopic drive.

[0033] As a preferred design, the first and second scrapers are arranged in a staggered manner, so that the material is subjected to forces from different positions during the leveling process. This staggered structure can more comprehensively cover the material, avoid leveling dead corners, and make the material more evenly distributed in the carriage, greatly improving the quality and effect of leveling.

[0034] As a preferred option, both the first scraper 6 and the second scraper 7 are plow-shaped scrapers. The plow tip of the plow-shaped scraper has low resistance to material insertion, and the working surface of the scraper is a plow-shaped curved surface, which can make the material quickly roll and spread to both sides, greatly accelerating the turning and leveling speed of the material, making the entire leveling process more efficient, saving the time cost required for leveling, and improving production efficiency.

[0035] As a preferred embodiment, elastic baffles 8 are installed at both ends of the inner side of the second scraper 5. The free ends of the elastic baffles extend outward from the ends of the second scraper. During the leveling process, the elastic baffles make elastic contact with both sides of the material box. On the one hand, this ensures that the material on both sides of the material box is fully leveled, avoiding material accumulation or unevenness on both sides. On the other hand, the elastic contact can buffer the collision force between the scraper assembly and the material box, preventing damage to the material box caused by rigid contact, ensuring the safety of the material box, and extending the service life of the equipment.

[0036] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
