Description

Technical Field

[0001] This utility model belongs to the field of scraping equipment, and more specifically, relates to a scraper conveyor body structure. Background Technology

[0002] A belt conveyor is a friction-driven machine that continuously transports materials. It mainly consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and a transmission system. It can transport materials along a specific conveying line from the initial feeding point to the final unloading point, forming a material transport process. It can transport both bulk materials and packaged goods. Besides pure material transport, it can also be integrated with the technological requirements of various industrial production processes to form rhythmic assembly line transport. Belt conveyors can be classified according to their conveying capacity into heavy-duty belt conveyors (such as mining belt conveyors) and light-duty belt conveyors (such as those used in the electronics, plastics, food, light industry, chemical, and pharmaceutical industries). Belt conveyors have the advantages of high conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. They utilize the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100 kg or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can transport materials uphill and downhill.

[0003] However, during the material conveying process, the surface of the belt tends to adhere to certain sticky materials. As the belt rubs against the lower idler rollers, these materials fall and accumulate below the belt, causing material waste and environmental pollution. To address this problem, existing technology uses a scraper conveyor installed below the belt to remove the fallen material and simultaneously scrape off the material adhering to the belt surface, thus solving the material accumulation problem.

[0004] For example, Chinese patent application number CN201910599503.8, published on January 5, 2021, discloses a reciprocating scraper cleaning machine, including a drive cylinder, a base plate, and a movable frame on the base plate. A scraper is provided within the movable frame, with an upper shaft and a lower shaft at both ends. The upper shaft is inserted into a first pin hole on the frame's edge, and the lower shaft passes through a second pin hole on the slider. When the drive cylinder drives the movable frame forward, the movable frame causes the upper shaft and scraper to rotate forward around the lower shaft. When the movable frame collides with the lower shaft, the lower edge of the scraper approaches the base plate and forms a first gap with the base plate, and the drive cylinder drives the movable frame to begin moving forward. When the drive cylinder drives the movable frame backward, the movable frame causes the upper shaft and scraper to rotate in the opposite direction around the lower shaft. When the movable frame collides with the lower shaft, the lower edge of the scraper leaves the base plate and forms a second gap with the base plate, and the drive cylinder drives the movable frame to begin moving backward. The first gap is smaller than the second gap.

[0005] For example, Chinese patent application number CN201621053533.7, published on March 22, 2017, discloses a belt-driven return scraper conveyor for sprinkling and cleaning materials, belonging to the field of material conveying equipment. It includes a frame, a tensioning device, and a motor. A head wheel axle is mounted on the front end of the frame via a front bearing seat, with a head wheel at each end of the axle. A tail wheel axle is mounted on the rear end of the frame via a rear bearing seat, with a tail wheel at each end. The head wheels and tail wheels are connected by a chain drive, which connects to a scraper. The motor is located at the front end of the frame and is connected to the head wheel axle. The tensioning device is located at the rear end of the frame and connected to the rear bearing seat, used to drive the tail wheel axle to move back and forth to adjust the chain tension.

[0006] Both of the aforementioned scraper conveyors are installed at the bottom of belt conveyors to remove materials that have fallen from the belt and to scrape off and transport materials adhering to the belt surface. However, in some complex external environments, when the scraper conveyor is installed under a horizontally positioned belt, the gap between the lower end of the belt conveyor and the ground is not consistently consistent. This means that if the scraper conveyor is directly fixed to the ground under the belt, the scraper blades may not be able to contact the material adhering to the belt surface. While fixing the scraper conveyor directly to its lower section ensures that the scraper blades contact the material, the scraper will be suspended in mid-air. Furthermore, due to the scraper's significant weight, over time, the connection between the scraper conveyor and the belt conveyor may loosen and detach, posing a safety hazard. Summary of the Invention

[0007] 1. The problem to be solved

[0008] The gap between the lower end of the existing horizontally mounted belt conveyor and the ground is not fixed, which makes it difficult to ensure that the scraper contacts the material adhering to the belt surface or that the lower end of the scraper cannot contact the ground during installation. This utility model provides a scraper conveyor body structure. By improving the assembly structure of the scraper conveyor body, the scraper conveyor can adapt to the installation of belt conveyors with different gaps, ensuring the working stability and installation strength of the scraper conveyor.

[0009] 2. Technical Solution

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] A scraper conveyor body structure includes a square frame, the square frame including a pair of side plates located on both sides of the scraper's moving direction; the body structure also includes a support plate, the support plate being fixedly installed on the outer side of the side plates, used to support and raise the scraper conveyor when it is installed below a belt conveyor, so that there is a gap between the bottom of the square frame and the ground.

[0012] As a further improvement to the technical solution, a plurality of waist-shaped holes extending in the height direction are provided on the outer side surface of the side plate, and a through hole matching the waist-shaped hole is provided on the support plate at the corresponding position. The support plate is fixedly installed on the bottom outer side of the side plate by bolts passing through the through hole and the waist-shaped hole.

[0025] 3. Beneficial effects

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] (1) The present invention provides a scraper conveyor body structure, wherein a support plate is installed on the outer side of the side plate of the body, which can be adjusted vertically through the waist-shaped hole. When the scraper conveyor is installed below the belt conveyor, if it is installed on the lower end surface of the belt conveyor, the lower end surface of the support plate can be supported on the ground by adjusting the height of the support plate, so as to prevent the scraper conveyor from being suspended and thus loosening and falling off the belt conveyor. If it is installed on the ground below the belt conveyor, the scraper can be made to contact the material adhering to the belt surface by adjusting the height of the support plate, and the material can be scraped off, thereby improving the cleaning ability of the scraper conveyor.

[0028] (2) The present invention provides a scraper conveyor body structure with multiple square frames. While meeting the body length requirements, this assembled body structure makes the conveying and installation of the scraper conveyor more convenient. By setting a pre-positioning plate with positioning holes, the two square frames can be aligned through the positioning holes when welding adjacent square frames, thus avoiding misalignment of the body and affecting the subsequent installation and use of the scraper conveyor.

[0029] (3) The present invention provides a scraper conveyor body structure, wherein a reinforcing beam is provided on the inner side of the square frame, which can effectively improve the structural strength of the body and increase the service life of the scraper conveyor.

[0030] (4) The present invention provides a scraper conveyor body structure, wherein the inclined structure on the outer side of the support plate makes the bottom of the support plate have a larger support area, thereby improving the installation strength of the scraper conveyor after installation.

[0033] Exemplary embodiments of the present invention are described in detail below. While these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to practice the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from its spirit and scope. The more detailed description of embodiments of the present invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to provide the best mode for carrying out the invention and sufficient to enable those skilled in the art to practice it. Therefore, the scope of the present invention is defined only by the appended claims.

[0034] Example 1

[0035] A scraper conveyor body structure is provided, which is the main installation part of the scraper conveyor. The head and tail of the machine are respectively installed at both ends of the machine body. The specific structure and technical effects of the machine body structure are described in detail below.

[0036] like Figure 1 As shown, the machine body structure includes a square frame 1 and a support plate 3. The square frame 1 includes a pair of side plates 2 located on both sides of the scraper's moving direction, and a pair of connecting plates located in the scraper's moving direction. The four plates form a square frame 1. The support plate 3 is fixedly installed on the outer surface of the side plates 2 and is used to support and raise the scraper when it is installed below the belt conveyor, so that there is a gap between the bottom of the square frame 1 and the ground.

[0037] When installing the scraper conveyor, the installation height of the support plate 3 on the side plate 3 is selected according to the on-site installation environment. This results in the following configuration: When the scraper conveyor is installed below a belt conveyor, if it is installed on the lower end face of the belt conveyor, adjusting the height of the support plate 3 ensures that the lower end face of the support plate 3 is supported on the ground, preventing the scraper conveyor from being suspended and loosening or falling off the belt conveyor. If it is installed on the ground below the belt conveyor, adjusting the height of the support plate 3 allows the scraper to contact the material adhering to the belt surface, scraping the material off and improving the cleaning capacity of the scraper conveyor. Therefore, the design of the support plate 3 in this application is not only for supporting the body of the scraper conveyor, but also, depending on the installation environment, can assist the scraper conveyor in scraping away material from the bottom of the belt conveyor.

[0038] It should be noted that in this embodiment, the scraper conveyor is installed below the horizontally positioned belt conveyor, and the distance between the return belt of the belt conveyor and the ground does not exceed 300mm. The support plate 3 in this embodiment is provided because the gap between the bottom of different belt conveyors and the ground will not be consistent during installation, while the specifications of the scraper conveyors produced on the same production line are consistent. Therefore, when the scraper conveyor is installed below different belt conveyors, there will inevitably be a mismatch between the height of the scraper conveyor and the gap between the bottom of the belt conveyor and the ground.

[0039] In this embodiment, by setting up a support plate 3 on-site and then installing it on the scraper conveyor, the support plate 3 can be installed at different heights on the side plate 2 according to the site environment. While supporting and raising the scraper conveyor, a gap exists between the bottom of the square frame 1 and the ground.

[0040] In this embodiment, each side plate 2 is equipped with a corresponding support plate 3, and the contact points of adjacent support plates 3 are welded together to improve the overall support strength of the support plates 3. At the same time, drainage holes are provided on the support plates 3 and the side plates 2, which can drain materials and some water accumulated in the environment through the drainage holes to the scraper machine, so as to avoid water accumulation affecting the operation of the scraper machine.

[0041] In this embodiment, the outer side of the support plate 3 is a slope that gradually extends from top to bottom towards the outside of the machine body, so that the bottom of the support plate 3 has a larger support area, thereby improving the installation strength of the scraper conveyor after installation.

[0042] The fuselage structure includes multiple square frames 1 arranged in sequence, with adjacent square frames 1 fixedly connected by welding. Simultaneously, a pair of pre-positioning plates 5 are provided at the contact points of the side plates 2 on both sides of two adjacent square frames 1, and positioning holes 6 are provided at corresponding positions on the pair of pre-positioning plates 5.

[0043] By setting multiple square frames 1, the assembled body structure not only meets the machine body length requirements but also makes the conveying and installation of the scraper conveyor more convenient. Furthermore, by setting a pre-positioning plate 5 with positioning holes 6, the two square frames 1 can be aligned during welding via the positioning holes 6, preventing misalignment of the machine body and ensuring the subsequent installation and use of the scraper conveyor.

[0044] Furthermore, two reinforcing beams 7 are installed on the inner side of each square frame 1. The two reinforcing beams 7 are arranged in a crisscross pattern and are welded to the square frame 1. The two reinforcing beams 7 within the same square frame 1 are welded together. This design of the reinforcing beams 7 effectively improves the structural strength of the machine body and increases the service life of the scraper conveyor. By installing a chain guide plate with guide grooves along the direction of chain movement above the side plate 2, the direction of the driven chain during operation will not deviate, ensuring the normal operation of the scraper conveyor.

[0045] In summary, the scraper conveyor body structure of this embodiment improves the assembly structure of the scraper conveyor, enabling it to adapt to the installation of belt conveyors with different clearances, thus ensuring the working stability and installation strength of the scraper conveyor.

[0046] Example 2

[0047] The scraper conveyor body structure in this embodiment is basically the same as that in embodiment 1. The difference is that multiple waist-shaped holes extending in the height direction are opened on the outer side surface of the side plate 2, and through holes 4 matching the waist-shaped holes are opened on the support plate 3 at the corresponding positions. The support plate 3 is fixedly installed on the bottom outer side of the side plate 2 by bolts passing through the through holes 4 and the waist-shaped holes. The height of the support plate 3 can be adjusted by adjusting the relative position of the through holes 4 and the waist-shaped holes.

[0048] When the scraper conveyor is installed below the belt conveyor, the height of the support plate 3 can be repeatedly adjusted in this way, making the adjustment more convenient and accurate. After the support plate 3 is fixed with bolts, the gap between the support plate 3 and the side plate 2 is welded to further strengthen the overall strength of the machine body structure and provide better support for the scraper conveyor.
