Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt scraping technology, specifically relating to a scraping device for a belt conveyor. Background Technology

[0002] Belt conveyors mainly consist of a conveyor belt and rollers. The rotation of the rollers drives the conveyor belt to move, thus transporting materials. During the conveying process, material often sticks to the conveyor belt. To facilitate material collection and avoid waste, scrapers are usually installed under the conveyor belt. The scrapers, attached to the outer surface of the conveyor belt, scrape the material off the belt. For easier collection later, a collection cylinder is typically used to guide the scraped material to a designated collection point on the ground. However, during use, scraper wear necessitates adjustments to the scraper's position. These adjustments alter the relative position of the collection cylinder's inlet to the scraper, potentially causing scraped material to fall onto the ground, requiring manual cleaning and increasing operator workload. Utility Model Content

[0003] This utility model provides a scraping device for a belt conveyor, which aims to solve the problem in the prior art that materials easily spill onto the ground after the scraper of the belt conveyor is adjusted, wasting the operator's labor.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a scraping device for a belt conveyor, comprising:

[0005] Fixture;

[0006] A lifting frame is mounted on the fixed frame, and the position of the lifting frame on the fixed frame has a degree of freedom to be adjusted in the vertical direction;

[0007] A scraper, mounted on the lifting frame, is used to scrape off material from the conveyor belt;

[0008] A receiving bin is hinged to the fixed frame, and the inlet of the receiving bin is located on one side of the scraper;

[0009] A support rod is mounted on the fixed frame, the support rod is supported at the bottom of the receiving hopper, and the position of the support rod on the fixed frame has a degree of freedom to be adjusted in the vertical direction.

[0010] In one possible implementation, the lifting frame is further equipped with a guide plate for guiding materials into the receiving hopper. The guide plate is located on one side of the scraper, and the discharge end of the guide plate is located at the inlet of the receiving hopper.

[0011] In one possible implementation, the top side of the guide plate abuts against the side of the scraper, and the bottom side of the guide plate extends into the inside of the receiving hopper.

[0012] In one possible implementation, the mounting bracket is provided with a plurality of placement slots for placing the support rod, and the plurality of placement slots are arranged at intervals along the vertical direction.

[0013] In one possible implementation, both ends of the support rod are equipped with limiting discs for limiting the movement of the support rod along its axial direction on the fixed frame.

[0014] In one possible implementation, the support rod is threaded with fasteners for abutting the limiting disc against the end face of the placement slot.

[0015] In one possible implementation, the lifting frame is provided with a fixing assembly for fixing the scraper, the fixing assembly comprising:

[0016] Two clamping plates are slidably disposed on the lifting frame relative to each other.

[0017] A drive rod is rotatably mounted on the lifting frame. Both clamping plates are provided with threaded holes that are threadedly connected to the drive rod, and the threads on the two clamping plates are arranged in opposite directions.

[0018] In one possible implementation, the lifting frame is provided with a guide groove for mounting a scraper, the scraper being inserted into the guide groove.

[0019] In one possible implementation, both ends of the lifting frame are equipped with lifting rods, which extend upward through the fixed frame and are threaded with nuts for abutting against the top surface of the fixed frame.

[0020] In one possible implementation, the hoisting rod is slidably mounted on the lifting frame in a vertical direction, and an elastic element for pushing the lifting frame upward is also installed between the hoisting rod and the lifting frame.

[0021] Compared with the prior art, the solution shown in this application embodiment has the following advantages: A fixed frame is installed below the roller or conveyor belt, and a scraper is mounted on the fixed frame. The top side of the scraper abuts against the bottom of the conveyor belt, thereby scraping off the material on the conveyor belt. The scraper is mounted on a lifting frame, the position of which can be freely adjusted vertically to ensure that the scraper always abuts against the side of the conveyor belt. In this application, a receiving hopper is hinged to the fixed frame. The bottom of the receiving hopper is hinged to the fixed frame near the discharge port. When the scraper moves up and down, the angle of the receiving hopper can be adjusted to move the inlet of the receiving hopper up and down with the scraper, reducing the gap between the scraper and the inlet of the receiving hopper. This allows the material scraped off by the scraper to fall stably into the receiving hopper, reducing the amount of material that spills onto the ground after being scraped off, avoiding unnecessary cleaning operations by operators, and thus reducing the labor intensity of operators.

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to the following: Figures 1 to 3The scraping device for a conveyor belt provided by this utility model will now be described. The scraping device includes a fixed frame 1, a lifting frame 2, a scraper 3, a receiving bin 4, and a support rod 5. The lifting frame 2 is mounted on the fixed frame 1, and its position on the fixed frame 1 has a degree of freedom for vertical adjustment; the scraper 3 is mounted on the lifting frame 2 and is used to scrape material off the conveyor belt; the receiving bin 4 is hinged to the fixed frame 1, and its inlet is located on one side of the scraper 3; the support rod 5 is mounted on the fixed frame 1, supports the bottom of the receiving bin 4, and its position on the fixed frame 1 has a degree of freedom for vertical adjustment.

[0029] Compared with the prior art, the material scraping device for the conveyor belt provided in this embodiment is equipped with a fixed frame 1, which is installed below the roller or conveyor belt. A scraper 3 is installed on the fixed frame 1, and the top side of the scraper 3 abuts against the bottom of the conveyor belt, so as to scrape the material off the conveyor belt. The scraper 3 is installed on a lifting frame 2, and the position of the lifting frame 2 on the fixed frame 1 can be freely adjusted in the vertical direction, so as to ensure that the scraper 3 always abuts against the side of the conveyor belt. In this application, a receiving bin 4 is hinged to a fixed frame 1. The bottom of the receiving bin 4 is hinged to the fixed frame 1 near the discharge port. When the scraper 3 moves up and down, the angle of the receiving bin 4 can be adjusted to make the inlet of the receiving bin 4 move up and down with the scraper 3, reducing the gap between the scraper 3 and the inlet of the receiving bin 4. This allows the material scraped off by the scraper 3 to fall stably into the receiving bin 4, reducing the amount of material that falls onto the ground after being scraped off by the scraper 3, avoiding unnecessary cleaning operations by the operator, and thus reducing the labor intensity of the operator.

[0030] Specifically, in this embodiment, the feed inlet of the receiving bin 4 is located directly below the scraper 3. After the receiving bin 4 is flipped upward to adjust the angle, the distance between the feed inlet of the receiving bin 4 and the scraper 3 can be reduced, reducing material splashing and allowing the material to fall stably into the receiving bin 4.

[0031] Preferably, in this embodiment, the bottom of the receiving hopper 4 is the discharge port, and the cross-sectional area of ​​the discharge port is smaller than that of the inlet. After the material flows out through the discharge port, it can be collected on the ground, which is convenient for the operators to clean and collect later.

[0032] In some embodiments, the lifting frame 2 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2The lifting frame 2 is also equipped with a guide plate 6 for guiding materials into the receiving hopper 4. The guide plate 6 is located on one side of the scraper 3, and its discharge end is located at the inlet of the receiving hopper 4. The guide plate 6 is installed on the lifting frame 2 and is located on the scraping side of the scraper 3. When the lifting frame 2 moves up and down, the guide plate 6 moves up and down with the lifting frame 2. The guide plate 6 is bent upwards on both sides along the length of the scraper 3 and is located on the outer side of both ends of the scraper 3. When the material falls onto the guide plate 6, it can prevent the material from falling from both ends of the guide plate 6. The side of the guide plate 6 away from the scraper 3 extends into the inlet of the receiving hopper 4, and the guide plate 6 is inclined downwards in the direction away from the scraper 3, thereby effectively guiding the material to flow into the receiving hopper 4.

[0033] In some embodiments, the guide plate 6 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The top side of the guide plate 6 abuts against the side of the scraper 3, and the bottom side of the guide plate 6 extends into the receiving hopper 4. The guide plate 6 includes a base plate for fixing to the lifting frame 2. A first inclined plate and a second inclined plate are bent at two opposite sides of the base plate. The first inclined plate abuts against the side of the scraper 3. The second inclined plate is inclined toward the inside of the receiving hopper 4 and extends into the receiving hopper 4. When the material falls along the scraper 3, it can fall into the receiving hopper 4 under the guidance of the first and second inclined plates.

[0034] Specifically, in this embodiment, a fixing plate for fixing to the lifting frame 2 is fixedly installed on the outer side of both ends of the substrate along the length direction of the scraper 3. An elongated through hole for fixing to the lifting frame 2 is provided on the fixing plate. The length direction of the elongated through hole is set along the conveying direction of the conveyor belt. So that after the scraper 3 is installed on the lifting frame 2, the position of the fixing plate on the lifting frame 2 can be adjusted so that the side of the first inclined plate abuts against the side of the scraper 3, preventing material from being stuck on the lifting frame 2.

[0035] Specifically, in this embodiment, both the first inclined plate and the second inclined plate are inclined downwards in a direction away from the scraper 3.

[0036] In some embodiments, the aforementioned fixing frame 1 may be as follows: Figure 1 The structure shown. See also Figure 1The fixed frame 1 is equipped with multiple placement slots for placing support rods 5, which are arranged alternately along the vertical direction. The fixed frame 1 includes two support frames spaced apart along the length of the scraper 3, and the two ends of the lifting frame 2 are slidably mounted on the two support frames respectively. Multiple placement slots are provided on the side walls of the support frames, and the ends of the support rods 5 can be placed into the placement slots. The multiple placement slots allow the height of the support rods 5 to be adjusted by placing them into different slots. The structure is simple and allows operators to freely adjust the height of the support rods 5.

[0037] Specifically, in this embodiment, the support rod 5 is located at the bottom of the receiving bin 4 and supports the receiving bin 4, limiting its downward tilting. The guide plate 6 extends into the receiving bin 4 and limits its upward tilting, thus confining the receiving bin 4 between the guide plate 6 and the support rod 5. Furthermore, during unloading, the receiving bin 4 can be shaken by swaying the support rod 5, causing any remaining material inside the receiving bin 4 to fall, reducing material residue.

[0038] In some embodiments, the support rod 5 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 Both ends of the support rod 5 are equipped with limiting plates 51 to restrict its movement along its axis on the fixing frame 1. The outer diameter of each limiting plate 51 is larger than the inner diameter of the placement groove. When both ends of the support rod 5 are installed inside the placement groove, the limiting plates 51 at both ends of the support rod 5 are positioned at the outer end faces of the placement groove, thus preventing the support rod 5 from moving along its length on the fixing frame 1 and detaching from the placement groove. This improves safety during use.

[0039] In some embodiments, the support rod 5 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The support rod 5 is threadedly connected to a fastener 52 for pressing the limiting disc 51 against the end face of the placement groove. A threaded hole is coaxially provided at the end of the support rod 5, and a bolt through hole is provided in the middle of the limiting disc 51. The fastener 52 is a bolt, which can pass through the limiting disc 51 and push it against the end of the placement groove, thus fixing the supporting rod 5 in place and further improving the stability of the support rod 5's position.

[0040] Preferably, in this embodiment, an anti-rotation edge is provided on one side of the limiting plate 51 for fitting to the side of the fixing frame 1. The anti-rotation edge can limit the rotation of the limiting plate 51, making it convenient to fasten the fastener 52.

[0041] In some embodiments, the fixing component 7 described above may be as follows: Figure 2 The structure shown. See also Figure 2The lifting frame 2 is equipped with a fixing assembly 7 for fixing the scraper 3. The fixing assembly 7 includes clamping plates 71 and a drive rod 72. There are two clamping plates 71, which are slidably mounted on the lifting frame 2 relative to each other. The drive rod 72 is rotatably mounted on the lifting frame 2. Both clamping plates 71 have threaded holes that are threadedly connected to the drive rod 72, and the threads on the two clamping plates 71 are arranged in opposite directions. The lifting frame 2 is made of square tubing, with clearance at the bottom to allow movement of the clamping plates 71. The scraper 3 is inserted inside the square tubing, and the two clamping plates 71 are located inside the square tubing. Therefore, when the drive rod 72 is rotated, it can drive the two clamping plates 71 to move closer together, thereby clamping the scraper 3 between the two clamping plates 71. This achieves the fixing of the scraper 3 on the lifting frame 2, with a simple structure and convenient operation.

[0042] Specifically, in this embodiment, mounting plates are installed on both sides of the square tube, and the drive rod 72 is rotatably mounted on the mounting plates on both sides. A limiting plate is provided on the drive rod 72 to restrict its movement along its axial direction, ensuring that the drive rod 72 can only rotate on the square tube.

[0043] Preferably, in this embodiment, multiple sets of fixing components 7 are provided on the lifting frame 2, and the multiple sets of fixing components 7 are arranged at intervals along the length direction of the scraper 3.

[0044] In some embodiments, the lifting frame 2 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The lifting frame 2 is equipped with a guide groove for installing the scraper 3, which is inserted into the guide groove. The lifting frame 2 is a square tube with a guide groove at the top. The scraper 3 is inserted into the guide groove, and its bottom side abuts against the inner wall of the bottom of the guide groove. The two sides of the scraper 3 slide against the inner wall of the guide groove, thus guiding the installation position of the scraper 3. Combined with the clamping of the two clamping plates 71, the stability of the fixed position of the scraper 3 can be improved.

[0045] In some embodiments, the lifting frame 2 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The lifting frame 2 has lifting rods 21 installed at both ends. The lifting rods 21 extend upwards and penetrate the fixed frame 1, and each lifting rod 21 is threaded with a nut 22 for abutting against the top surface of the fixed frame 1. The lifting rods 21 are fixedly installed at both ends of the lifting frame 2, and the top of each lifting rod 21 has a threaded portion that connects to the nut 22. By rotating the nut 22, the height of the lifting rod 21 on the fixed frame 1 can be adjusted, thereby adjusting the height of the scraper 3. The height of the scraper 3 can be freely adjusted according to the degree of contact between the scraper 3 and the conveyor belt.

[0046] Preferably, in this embodiment, a support member is threadedly connected to the lifting rod 21, and a crossbeam for installing the lifting rod 21 is provided on the fixing frame 1. The support member and the nut 22 are located on the upper and lower sides of the crossbeam, respectively. By tightening the support member and the nut 22 onto the crossbeam, the stability of the lifting rod 21 can be improved.

[0047] In some embodiments, the lifting rod 21 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The lifting rod 21 is slidably mounted on the lifting frame 2 in a vertical direction, and an elastic element 23 for pushing the lifting frame 2 upward is installed between the lifting rod 21 and the lifting frame 2. The lifting rod 21 is slidably mounted on the lifting frame 2, and a limit platform is provided at the bottom end of the lifting rod 21. The elastic element 23 is a spring, which is fitted on the outside of the lifting rod 21, with the bottom end of the elastic element 23 abutting against the limit platform and the top end of the elastic element 23 abutting against the lifting frame 2, thereby pushing the lifting frame 2 upward and ensuring that the scraper 3 can always be in contact with the bottom surface of the conveyor belt, thus ensuring stability during the scraping process.

[0048] The above description is only a preferred embodiment of the present utility model and is 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.
