Description

Technical Field

[0001] The utility model belongs to the technical field of scraper conveyors, in particular to a wear-resistant device for a scraper conveyor. Background Technique

[0002] A scraper conveyor is an important device for conveying materials in the fields of feed, grain, coal, metallurgy, etc. However, due to the physical properties, particle size, and hardness of the conveyed materials, it has an important impact on the service life and failure rate of the scraper conveyor. As an important device for conveying feed materials in a feed processing plant, a scraper conveyor is usually installed at the parallel positions of the inlet and outlet of the raw material bin and the outlet of the feed finished product bin, and the space is relatively narrow. A scraper conveyor mainly consists of a box body, a chain, a scraper, a support bar, and a rotating shaft with gears at both ends. The rotating shafts at both ends of the scraper conveyor are controlled by a motor. The gears at both ends of the rotating shaft fit with the chain to drive the chain to rotate. The chain is horizontally connected to the scraper. There is a support bar at the bottom and top of the box body of the scraper conveyor respectively, which is used to support the movement of the chain and the scraper. Driven by the motor, the scraper drives the material to be conveyed to a specified position in the direction of the chain rotation during the movement.

[0003] During the material conveying process, due to the long-term friction between the material, the scraper and the inner wall and bottom of the scraper conveyor, it is easy to cause wear on the inside and bottom of the scraper conveyor, and it is necessary to regularly repair and replace the scraper conveyor. Usually, the position where the scraper conveyor is located has a narrow space. After damage, material leakage, dust, and particles spread wantonly, which causes great damage to production safety and environmental protection. In addition, the working conditions are relatively harsh, and it is difficult for operators to repair. Under normal circumstances, when the scraper conveyor conveys about 15,000 tons of materials, the box body of the scraper conveyor is severely damaged and must be overhauled or replaced. The cost of each repair is about 138,000 yuan, the repair cycle is relatively long, about 13 days, the repair cost is high, and the service life after repair has not been improved, and the equipment performance is in a gradually deteriorating trend. This innovative achievement, without making major changes to the equipment, process, and materials, improves the service life of the equipment by reducing the area of continuous contact and rubbing between the material and the equipment, reducing or lowering the running friction of the material on the equipment facilities, and preventing the device from being damaged. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wear-resistant device for a scraper conveyor to solve the problems raised in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A wear-resistant device for a scraper conveyor, comprising a scraper conveyor pipeline, a plurality of stainless steel chains, and a plurality of stainless steel scrapers for scraping materials. A cross beam is welded to the inner side wall of the scraper conveyor pipeline. At both ends of the top of the cross beam, electric telescopic rods are installed. The moving ends of the two electric telescopic rods are detachably connected with a moving plate through bolts. A stainless steel grid plate is arranged on the top surface of the moving plate. A plurality of blocking plates are inserted into a plurality of mesh holes of the stainless steel grid plate. The bottom surfaces of the plurality of blocking plates are fixedly connected with the moving plate. Connecting plates are fixedly connected to both side surfaces of the moving plate. A limiting rod is embedded and slidably connected to the top surface of the connecting plate. A limiting plate is welded to the top surface of the limiting rod. The adjacent sides of the two limiting plates are fixedly connected with the stainless steel grid plate.

[0006] Preferably, a limiting block is fixedly connected to the bottom surface of the limiting rod. The plurality of blocking plates arranged on the top surface of the moving plate are arranged in an array.

[0007] Preferably, the top surface of the limiting block abuts against the bottom surface of the connecting plate. Stainless steel light plates with a smooth surface are welded to both side surfaces of the stainless steel grid plate.

[0008] Preferably, the centrifugal sides of the two stainless steel light plates are welded to the side wall of the scraper conveyor pipeline.

[0009] Preferably, the plurality of stainless steel scrapers and the stainless steel chains are arranged on the adjacent sides of the two stainless steel light plates. The plurality of stainless steel scrapers and the stainless steel chains are arranged alternately.

[0010] Preferably, the side surface of the stainless steel scraper is rotatably connected to the stainless steel chain through a pin shaft. Both end surfaces of the stainless steel scraper are slidably connected to the two stainless steel light plates.

[0011] Preferably, the top surface of the stainless steel grid plate is in sliding friction contact with the stainless steel scraper.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] For this wear-resistant device of the scraper conveyor, the output shaft of the driving motor drives the driving sprocket to rotate, and then the driving sprocket drives the stainless steel chain, so as to realize the position movement of a plurality of stainless steel scrapers and achieve the conveying effect of materials. By making the materials accumulate on the top surface of the stainless steel grid plate, a plurality of stainless steel scrapers scrape and convey the materials on the top surface of the stainless steel grid plate. At the same time, the stainless steel grid plate is of a grid structure, which is convenient for reducing the sliding friction area between the top surface of the stainless steel grid plate and the bottom surface of the stainless steel scraper, shortening the sliding friction and rubbing area of the device, preventing the device from being damaged due to sliding friction and rubbing, and thus extending the service life of the device. By setting the connecting plate to fix the moving path of the limiting rod, the relative position movement stability between the stainless steel grid plate and the moving plate is improved during the transmission process.

[0014] The wear-resistant device of this scraper conveyor is provided with several blocking plates inside several mesh holes of the stainless steel mesh plate, which is convenient for adjusting the amount of accumulated materials inside the mesh holes of the stainless steel mesh plate. At the same time, it is convenient to provide power through the electric telescopic rod to move the mobile end of the electric telescopic rod, and adjust the distance between the stainless steel mesh plate and the moving plate during the transmission process. Thus, when the blocking plate moves, its top surface is flush with the top surface of the stainless steel mesh plate, pushing out the materials accumulated in the mesh holes of the stainless steel mesh plate. This is convenient for providing a conveying function for the materials accumulated in the mesh holes of the stainless steel mesh plate after the device completes the material conveying, and improving the stability of the functional structure of the device.

Detailed Embodiments

[0023] In the following description, numerous specific details are given to provide a more thorough understanding of the present utility model. However, it will be apparent to those skilled in the art that the present utility model can be practiced without one or more of these details. In other instances, some well-known technical features are not described to avoid obscuring the present utility model.

[0024] Unless otherwise defined, the directions such as up, down, left, right, front, back, inner, and outer involved herein are based on the up, down, left, right, front, back, inner, and outer directions in the figures shown in the present utility model, which are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0026] To solve the problem that the material continuously rubs against the equipment during the use of the wear-resistant device of the scraper conveyor, causing damage to the device and shortening the service life of the device, please refer to Figures 1 to 5 , the structure of the device body is as follows: a scraper conveyor pipeline 1, several stainless steel chains 5, and several stainless steel scrapers 4 for scraping materials. A cross beam 9 is welded to the inner side wall of the scraper conveyor pipeline 1, so that the scraper conveyor pipeline 1 provides support and fixation for the cross beam 9. At both ends of the top of the cross beam 9, electric telescopic rods 8 are installed. The fixed ends of the two electric telescopic rods 8 are detachably connected to the top surface of the cross beam 9 by bolts, so that the cross beam 9 provides support and fixation for the two electric telescopic rods 8, improving the structural stability of the components of the wear-resistant device of the scraper conveyor. The moving ends of the two electric telescopic rods 8 are detachably connected to a moving plate 7 by bolts, facilitating the longitudinal movement of the moving plate 7 driven by the moving ends of the two electric telescopic rods 8 during the movement. A stainless steel grid plate 3 is arranged on the top surface of the moving plate 7.

[0027] A blocking plate 6 is inserted into each of the several mesh holes of the stainless steel grid plate 3, facilitating the blocking effect of the several blocking plates 6 on the several mesh holes of the stainless steel grid plate 3. At the same time, it is convenient to stack materials through the several mesh holes of the stainless steel grid plate 3. When the several stainless steel scrapers 4 scrape and convey the materials on the top surface of the stainless steel grid plate 3, since the stainless steel grid plate 3 is a grid structure, it is convenient to reduce the contact area between the top surface of the stainless steel grid plate 3 and the stainless steel scrapers 4, thereby reducing the sliding friction and rubbing area of the components of the wear-resistant device of the scraper conveyor, preventing the components of the wear-resistant device of the scraper conveyor from being damaged due to friction and rubbing, and thus extending the service life of the device. The bottom surfaces of the several blocking plates 6 are fixedly connected to the moving plate 7, facilitating the shortening of the distance between the moving plate 7 and the stainless steel grid plate 3.

[0028] Push the material temporarily stored in the mesh holes of the stainless - steel grid plate 3 by the blocking plate 6 to improve the conveying effect of the device on the material. Both sides of the moving plate 7 are fixedly connected with connecting plates 10. The top surface of the connecting plate 10 is embedded and slidably connected with a limiting rod 11. The arranged connecting plate 10 fixes the moving path of the limiting rod 11. The top surface of the limiting rod 11 is welded with a limiting plate 12 to improve the relative movement stability between the moving plate 7 and the stainless - steel grid plate 3 during the transmission process. The adjacent sides of the two limiting plates 12 are fixedly connected with the stainless - steel grid plate 3. The bottom surface of the limiting rod 11 is fixedly connected with a limiting block 13. The top surface of the limiting block 13 abuts against the bottom surface of the connecting plate 10. The arranged limiting block 13 prevents the limiting rod 11 from detaching from the connecting plate 10 during the movement process, and at the same time controls the relative movement interval between the limiting rod 11 and the connecting plate 10, preventing the blocking plate 6 and the stainless - steel grid plate 3 from detaching when they move relatively, and improving the structural stability of the device components.

[0029] A number of blocking plates 6 arranged on the top surface of the moving plate 7 are arranged in an array, and the number of the arranged blocking plates 6 corresponds to the number of mesh holes of the stainless - steel grid plate 3 one by one. Both sides of the stainless - steel grid plate 3 are welded with stainless - steel smooth plates 2 with a smooth surface. The two arranged stainless - steel smooth plates 2 provide a shielding effect. At the same time, the surface of the stainless - steel smooth plate 2 is smooth, reducing the frictional resistance of the relative sliding between the material and the stainless - steel smooth plate 2, preventing damage to the stainless - steel smooth plate 2, and further extending the service life of the device. The centrifugal sides of the two stainless - steel smooth plates 2 are welded to the side wall of the scraper conveyor pipeline 1. The arranged scraper conveyor pipeline 1 provides a supporting and fixing effect on the two stainless - steel smooth plates 2, and at the same time, the two arranged stainless - steel smooth plates 2 are symmetrically arranged on both sides of the stainless - steel grid plate 3.

[0030] A number of stainless - steel scrapers 4 and stainless - steel chains 5 are arranged adjacent to the two stainless - steel smooth plates 2. By driving the driving sprocket to rotate during the rotation of the output shaft of the driving motor, the driving sprocket then pulls the stainless - steel chain 5, and during the transmission process, the stainless - steel scraper 4 scrapes and conveys the material. A number of stainless - steel scrapers 4 and stainless - steel chains 5 are arranged alternately. The side of the stainless - steel scraper 4 is rotationally connected to the stainless - steel chain 5 through a pin shaft, facilitating the relative rotation between the stainless - steel chain 5 and the stainless - steel scraper 4, and improving the flexibility of the movement of the components of the scraper conveyor wear - resistant device. The two end faces of the stainless - steel scraper 4 are slidably connected with the two stainless - steel smooth plates 2, and the top surface of the stainless - steel grid plate 3 is in sliding friction contact with the stainless - steel scraper 4.

[0031] The electric telescopic rod 8 is an existing technology, and its working principle, size and model are irrelevant to the function of this application, so no more description is made. The control mode of the present utility model is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art, and since the present utility model mainly protects mechanical devices, the control mode and circuit connection of the present utility model are not explained in detail.

[0032] Working principle

[0033] For this wear-resistant device of the scraper conveyor, when in use, the user guides the material onto the top surface of the stainless-steel grid plate 3, causing the material to flow into several mesh holes of the stainless-steel grid plate 3. During the rotation of the output shaft of the driving motor, the driving sprocket is driven to rotate, and then the driving sprocket pulls the stainless-steel chain 5 to move, so that the stainless-steel scraper 4 scrapes and conveys the material on the top surface of the stainless-steel grid plate 3. Through the grid structure presented by the stainless-steel grid plate 3, the sliding friction and scraping area between the stainless-steel scraper 4 and the stainless-steel grid plate 3 is reduced, and the service life of the device is prolonged.

[0034] Start two electric telescopic rods 8. During the movement of the moving end of the electric telescopic rod 8, the moving plate 7 is driven to move, and then several blocking plates 6 push out the material in the mesh holes of the stainless-steel grid plate 3, facilitating the conveying of the material by the stainless-steel scraper 4. The provided connecting plate 10 fixes the moving path of the limiting rod 11, thereby improving the relative movement stability between the moving plate 7 and the stainless-steel grid plate 3. The provided limiting block 13 prevents the limiting rod 11 from detaching from the connecting plate 10 during movement.
