Description

Technical Field

[0001] This utility model provides a coal feeding and weighing device for top-loading coal cars, belonging to the technical field of coal car feeding equipment. Background Technology

[0002] In industries such as thermal power generation and coking, top-loading coal cars are widely used in coal mines and industrial plants as a highly efficient coal loading device. Top-loading coal cars can quickly complete coal transfer and feeding through top loading, significantly improving operational efficiency. However, during the coal loading and unloading process, the weighing process is crucial for production proportioning and cost control. Therefore, top-loading coal cars are usually equipped with dedicated weighing devices to monitor the coal loading volume in real time, ensuring the accuracy and reliability of the data. Existing weighing devices for coal cars are often weighing platforms, with the coal car having an open top structure. During coal feeding, the coal car is placed on the weighing platform, and coal is fed while being weighed, thus monitoring the weight.

[0003] Because coal itself has a high dust content, fine coal particles are easily scattered. For coal cars with long loading times, dust and coal particles disperse from the large openings at the top of the car for extended periods. Compared to short-duration loading and unloading scenarios, this results in more dust and coal particles adhering to the weighing platform surface, increasing contamination and potentially affecting weighing accuracy. Furthermore, cleaning the weighing platform surface typically requires manual cleaning by hand using a handheld hose, or temporary installation of a fixed cleaning pipe. This operation is not only time-consuming and labor-intensive but also increases the workload for workers. Therefore, there is an urgent need for a top-loading coal car weighing device that effectively prevents dust and facilitates cleaning, thus solving the current pollution and cleaning problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that for coal cars with long coal feeding times, dust and coal particles increase the pollution of the symmetrical weighing platform; in addition, cleaning the symmetrical weighing platform often requires manual hand-held flushing pipes or the installation of temporary flushing pipes, which is cumbersome.

[0005] To solve the above problems, the proposed technical solution is as follows: a coal weighing device for top-loading coal cars, including a weighing platform for weighing the coal car, and a support frame installed on the rear side of the weighing platform; a screw feeder is installed on the support frame, and a feed pipe for conveying coal into the coal car is connected below the screw feeder; further comprising: The lifting plate and dustproof frame are provided. The lifting plate is located above the coal car and is slidably mounted on the support. The upper end of the coal car has a groove, into which a dustproof frame that can be inserted to seal the opening at the upper end of the coal car is fixedly connected to the lower part of the lifting plate. Several nozzles located in the dustproof frame and capable of rinsing the symmetrical platform surface are provided below the lifting plate. A water supply structure communicating with the nozzles is provided on the rear side of the support.

[0006] As an improvement, the lifting plate is slidably sleeved on the feed pipe, and the lower end of the feed pipe is located inside the dustproof frame.

[0007] As an improvement, the bracket is equipped with an electric telescopic rod, and the working end of the electric telescopic rod is fixedly connected to the lifting plate.

[0008] As an improvement, the water supply structure includes a water tank, a water pump, and a water supply pipe; the water tank is located on the rear side of the support, the water tank is connected to the water supply pipe through the water pump, and the water supply pipe is connected to the nozzle.

[0009] As an improvement, the coal car is equipped with wheels with locking function at the bottom, and a handle is fixedly connected to the coal car to facilitate pushing by the workers; auxiliary inclined plates are provided on both sides of the weighing platform to facilitate the coal car going up and down.

[0010] As an improvement, the weighing platform is provided with marking points to facilitate the positioning of coal cars, and the marking points correspond to the wheels of the coal cars.

[0011] The beneficial effects of this utility model are: 1. A groove is provided at the top of the coal car, into which a dustproof frame that can be inserted to seal the opening at the top of the coal car is fixedly connected to the bottom of the lifting plate; by setting a dustproof frame that can be inserted into the groove, the opening at the top of the coal car can be sealed when feeding coal, greatly reducing the pollution of the symmetrical weighing platform caused by the diffusion of dust and coal particles.

[0012] 2. Several nozzles are installed below the lifting plate, located within a dustproof frame, to rinse the surface of the symmetrical weighing platform. By pre-setting the nozzles below the lifting plate, when rinsing the symmetrical weighing platform, there is no need for workers to hold them or install temporary cleaning pipes; simply activating the water supply structure simplifies the operation.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] This utility model provides a coal feeding and weighing device for a top-loading coal car: it includes a weighing platform 6 for weighing the coal car 5, and a support 3 is provided on the rear side of the weighing platform 6; a screw feeder 1 is provided on the support 3, and a feed pipe 2 for conveying coal into the coal car 5 is connected below the screw feeder 1; the screw feeder 1 is a commonly used coal feeding machine, which can ensure the uniformity of the coal feeding speed, and the specific structure of the screw feeder 1 will not be described here.

[0020] like Figure 2 As shown, the lifting plate 4 is located above the coal car 5, and the lifting plate 4 is slidably mounted in the bracket 3; the bracket 3 is equipped with an electric telescopic rod 9, and the working end of the electric telescopic rod 9 is fixedly connected to the lifting plate 4. A groove 7 is provided at the upper end of the coal car 5. A dustproof frame 8, which can be inserted into the groove 7 to seal the opening at the upper end of the coal car 5, is fixedly connected to the lower part of the lifting plate 4. The lifting plate 4 is slidably sleeved on the feed pipe 2, and the lower end of the feed pipe 2 is located inside the dustproof frame 8. Using an electric telescopic rod 9, the dustproof frame 8 can be moved down through the lifting plate 4, thereby sealing the opening of the coal car 5 and ensuring that a large amount of dust and coal particles do not escape when the feed pipe 2 feeds coal to the coal car 5.

[0021] like Figure 3 , 4 As shown, several nozzles 13 are located below the lifting plate 4, within the dustproof frame 8, and capable of rinsing the surface of the symmetrical weighing platform 6. A water supply structure connected to the nozzles 13 is located on the rear side of the support 3. The water supply structure includes a water tank 10, a water pump 11, and a water supply pipe 12. The water tank 10 is located on the rear side of the support 3 and is connected to the water supply pipe 12 via the water pump 11. The water supply pipe 12 is also connected to the nozzles 13. By placing the nozzles 13 below the lifting plate 4, the surface of the symmetrical weighing platform 6 can be rinsed directly without the need for temporary installation of rinsing pipes or workers holding rinsing pipes.

[0022] like Figure 4 As shown, the coal car 5 has wheels with locking function at the bottom for easy fixing, and a handle 14 is fixedly connected to the coal car 5 for easy pushing by workers. The weighing platform 6 has marking points 16 for easy positioning of the coal car 5, and these marking points 16 correspond to the wheels of the coal car 5. When the wheels of the coal car 5 correspond to the marking points 16, the groove 7 inside the coal car 5 corresponds to the dustproof frame 8. Auxiliary inclined plates 15 are provided on both sides of the weighing platform 6 to facilitate the movement of the coal car 5.

[0023] The principle of this utility model When using this application, the coal car 5 is pushed from the auxiliary inclined plate 15 onto the weighing platform 6. After positioning the coal car 5 using the marking point 16, the locking function of the coal car 5's wheels is used to fix the coal car 5 in place, ensuring that the groove 7 of the coal car 5 corresponds to the position of the dustproof frame 8. For example... Figure 1 , 2 As shown, activating the electric telescopic rod 9 moves the lifting plate 4 and dustproof frame 8 downwards, causing the dustproof frame 8 to insert downwards into the groove 7, without exerting downward pressure on the coal car 5. Coal is fed into the coal car 5 using the screw feeder 1 and feed pipe 2. Due to the sealing effect of the dustproof frame 8, the diffusion of dust and coal particles is greatly reduced, thus significantly reducing the contamination of the weighing platform 6 by dust and coal particles. It should be noted that to ensure weighing accuracy, this structure is not completely sealed; a small gap remains between the dustproof frame 8 and the groove 7. Furthermore, due to the sliding connection between the lifting plate 4 and the feed pipe 2, this connection is not completely sealed. However, compared to the completely open coal feeding state of the coal car 5, the dustproof frame 8 provided in this application significantly improves the sealing effect and solves the problems mentioned in the background art. When the weighing platform 6 is about to reach the set value, in order to ensure the accuracy of weighing, the electric telescopic rod 9 is activated at this time, which drives the dustproof frame 8 to completely separate from the coal car 5 and not contact it. At the same time, there is a small gap between the dustproof frame 8 and the coal car 5 to reduce the spread of dust. In this state, coal feeding continues until the set value of the weighing platform 6 is reached.

[0024] As can be seen from the above, during long-term coal feeding, the dustproof frame 8 can greatly reduce the diffusion of dust and coal particles, reduce the pollution of the weighing platform 6, and, based on the weighing results of the weighing platform 6, the dustproof frame 8 is only separated from the coal car 5 when the set value is almost reached. Some dust will flow out from the gap between the dustproof frame 8 and the coal car 5, but because the time is short and the dust outflow is reduced by controlling the gap between the dustproof frame 8 and the coal car 5, the pollution of the weighing platform 6 can be greatly reduced compared to the situation where the coal car 5 is completely open.

[0025] Additionally, when it is necessary to rinse the surface of the symmetrical platform 6, such as Figure 4 As shown, when the coal car 5 is not placed on the weighing platform 6, the nozzle 13 is directly aligned with the weighing platform 6 downwards; the water pump 11 is directly started, and the surface of the weighing platform 6 is rinsed using the water pipe 12 and the nozzle 13. There is no need for staff to hold the rinsing pipe or install a temporary rinsing pipe, which greatly improves the rinsing efficiency of the weighing platform 6.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
