Description

Technical Field

[0001] This utility model relates to the technical field of stone slag funnel carts, specifically a funnel cart that facilitates the loading and unloading of stone slag. Background Technology

[0002] Hopper cars can be classified into two types based on their structure: covered and uncovered. Railway hopper cars are all covered or uncovered hopper cars used for transporting cold materials. However, metallurgical and coking enterprises, to meet production needs, also have hopper cars for transporting hot materials, such as coke quenching cars, hot sintering ore cars, and hopper-type weighing cars. Regardless of the type, the common feature of unloading hopper cars is that, to allow the goods to slide down under their own weight for unloading, the car body is equipped with a funnel plate at a certain angle to the horizontal, and the unloading door is located at the bottom or side of the car body.

[0003] Existing hopper cars have self-unloading capabilities; however, their discharge openings are short and have a fixed orientation, meaning materials can only fall beside the track at the bottom of the hopper car. While these hopper cars can meet certain needs for loading and unloading ready-to-use railway laying materials, they are also currently used to transport spare materials such as stone chips. This requires unloading materials at different locations, and existing hopper cars cannot adjust the unloading position according to the actual needs of the working conditions or unloading site, thus limiting their usability. Therefore, we propose a hopper car that facilitates the loading and unloading of stone chips. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a hopper car that facilitates the loading and unloading of stone chips, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hopper car for easy loading and unloading of stone chips includes a base plate and a car body disposed on the base plate. The bottom end of the car body is connected to a hopper, the bottom end of which penetrates the base plate and is provided with a discharge port for discharging material. A cover plate component and a pressure plate component are disposed below the base plate to close the opening, and an extension component is connected to the pressure plate component.

[0007] Furthermore, the pressure plate component includes a feeding pressure plate, one end of which is hinged to the feeding hopper via a mounting base, and the other end of which is connected to a hydraulic cylinder.

[0008] Furthermore, the extension component includes a limiting frame, which is fixedly installed at the bottom of the unloading pressure plate, and an extension plate is movably connected inside the limiting frame.

[0009] Furthermore, the extension component also includes a mounting plate, one end of which is fixedly mounted on the unloading pressure plate, and a second hydraulic cylinder is fixedly mounted on the mounting plate. One end of the extension plate is connected to the output end of the second hydraulic cylinder, and the other end of the extension plate is a free end that can extend away from the mounting plate.

[0010] Furthermore, one end of the hydraulic cylinder is hinged to the bottom of the base plate, and the other end of the hydraulic cylinder is hinged to the unloading pressure plate.

[0011] Furthermore, the cover plate component includes a connecting plate, one end of which is fixedly installed on the bottom of the base plate, and the other end of which is hinged to the cover plate body.

[0012] Furthermore, a limiting rope is fixedly installed at one end of the cover plate body away from the connecting plate, and one end of the limiting rope is fixedly installed at the bottom of the base plate.

[0013] By employing the above technical solution, this utility model provides a hopper car that facilitates the loading and unloading of stone chips. It possesses at least the following beneficial effects:

[0014] This hopper car, which facilitates the loading and unloading of stone chips, can extend the length of the discharge plate by setting an extension component on the pressure plate component. This extends the material's travel distance during unloading, allowing the material to be unloaded at a location far from the hopper car and track, thus adapting to actual construction conditions and the actual needs of different unloading sites.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides a technical solution as follows:

[0023] A hopper car for easy loading and unloading of stone chips includes a base plate 1 and a carriage 2 mounted on the base plate 1. The carriage 2 is used to load stone chips, and a hopper 3 is connected to the bottom of the carriage 2. The bottom of the hopper 3 penetrates the base plate 1 and has a discharge port for discharging material. The top of the hopper 3 communicates with the carriage 2 for unloading stone chips. A cover plate component 4 and a pressure plate component 5 are provided below the base plate 1 to close the opening. An extension component 6 is connected to the pressure plate component 5. Existing stone chip hopper cars have a short discharge port at the bottom, causing the unloaded material to accumulate at the side of the track. However, the hopper car in this embodiment can extend the length of the discharge port by setting the extension component 6, allowing the stone chips to be unloaded at a distance from the track.

[0024] Please see Figure 2 and Figure 3 The cover plate component 4 includes a connecting plate 403. One end of the connecting plate 403 is fixedly installed on the bottom of the base plate 1, and the other end of the connecting plate 403 is hinged to the cover plate body 401. The cover plate body 401 can rotate within a certain range, thereby sealing or opening the discharge opening at the bottom of the hopper 3. A limiting rope 402 is fixedly installed on the end of the cover plate body 401 away from the connecting plate 403. One end of the limiting rope 402 is fixedly installed on the bottom of the base plate 1. The length of the limiting rope 402 is fixed, which can limit the rotation angle of the cover plate body 401, preventing the cover plate body 401 from completely leaving the range of motion of the pressure plate component 5, thereby facilitating its use in conjunction with the pressure plate component 5.

[0025] Please continue reading. Figure 2 and Figure 3 The pressure plate component 5 includes a discharge pressure plate 501. One end of the discharge pressure plate 501 is hinged to the discharge hopper 3 via a mounting base 502. The upper surface of the discharge pressure plate 501 abuts against the lower surface of the cover plate body 401, pressing the cover plate body 401 tightly onto the bottom opening of the discharge hopper 3, so that the discharge port is in a closed state.

[0026] Furthermore, a hydraulic cylinder 503 is connected to the other end of the discharge plate 501. The hydraulic cylinder 503 is used to control the angle of the discharge plate 501. Specifically, one end of the hydraulic cylinder 503 is hinged to the bottom of the base plate 1, and the other end of the hydraulic cylinder 503 is the output end and is hinged to the discharge plate 501. During the loading and unloading of stone chips, the hydraulic cylinder 503 can provide a certain force to make the discharge plate 501 press against the cover plate body 401. During unloading, the extension of the output end of the hydraulic cylinder 503 can drive the unloading plate 501 to rotate, thereby reducing the pressure of the unloading plate 501 on the cover plate body 401. At this time, the cover plate body 401 will automatically swing under its own weight and the weight of the material above it. Since the upper surface of the unloading plate 501 and one end of the cover plate body 401 are always in contact within a certain angle range, the material falling from the unloading hopper 3 will not be directly transported out of the hopper car, but will stay between the unloading plate 501 and the cover plate body 401, so that the operator can make adaptive adjustments to the angle of the unloading plate 501 and the length of the extension component 6 according to the actual conditions of the unloading site.

[0027] In one embodiment, the extension component 6 includes a limiting frame 601, which is fixedly installed at the bottom of the unloading pressure plate 501. An extension plate 602 is movably connected inside the limiting frame 601. The limiting frame 601 is U-shaped. The top surface of the extension plate 602 contacts the bottom surface of the unloading pressure plate 501. The bottom surface and two opposite sides of the extension plate 602 are in contact with the inner surface of the limiting frame 601. Therefore, the extension plate 602 can be limited by the limiting frame 601.

[0028] The extension component 6 also includes a mounting plate 604. One end of the mounting plate 604 is fixedly mounted on the unloading pressure plate 501. A hydraulic cylinder 603 is fixedly mounted on one side of the mounting plate 604. The hydraulic cylinder 603 is used to provide power for the movement of the extension plate 602. One end of the extension plate 602 is connected to the output end of the hydraulic cylinder 603. The other end of the extension plate 602 is a free end and can extend away from the mounting plate 604 to extend the length of the unloading pressure plate 501. When loading stone chips, the extension plate 602 can be controlled to retract by the hydraulic cylinder 603. When unloading stone chips, the extension plate 602 can be controlled to extend outside the hopper car by the hydraulic cylinder 603 to increase the length of the unloading plate and the movement stroke of the material during unloading, so as to meet the actual unloading needs of different sites.

[0029] Working principle: Before loading the stone chips, hydraulic cylinder 503 controls the angle of the discharge plate 501, causing its upper surface to abut against the lower surface of the cover plate body 401, pressing the cover plate body 401 firmly against the bottom opening of the discharge hopper 3, thus closing the discharge hopper 3. Hydraulic cylinder 603 controls the position of the extension plate 602, causing it to retract into the bottom of the funnel car. During the stone chip loading process, the bottom of the discharge hopper 3 remains closed to prevent material spillage.

[0030] When unloading stone chips, the hopper car is on the track, making it inconvenient to adjust the position of the car itself. Therefore, the angle and length of the discharge plate can be adjusted according to the actual needs of the unloading site, thereby changing the unloading position. Specifically, first, hydraulic cylinder 503 is activated. The output end of hydraulic cylinder 503 extends and pushes the discharge plate 501, causing the discharge plate 501 to rotate around its hinge point with the discharge hopper 3. During the rotation of the discharge plate 501, the cover plate body 401 will automatically swing under its own weight and the weight of the material above it. It is necessary to maintain contact between the discharge plate 501 and the cover plate body 401 so that the material remains between them. Then, hydraulic cylinder 603 is activated, and the output end of hydraulic cylinder 603 extends and pushes the extension plate 602 outward from the hopper car. After adjusting the length of the extension plate 602 according to the actual needs of the unloading site, hydraulic cylinder 503 continues to push the discharge plate 501, so that the discharge plate 501 is completely separated from the cover plate body 401. At this time, the material can fall onto the discharge plate 501 along the cover plate body 401, and then fall onto the unloading site along the discharge plate 501 and the extension plate 602.

[0031] After unloading is completed, hydraulic cylinders 503 and 603 are reset. Hydraulic cylinder 503 drives the unloading plate 501 to rotate in the opposite direction. During the rotation, the unloading plate 501 contacts one end of the cover plate body 401 and drives the cover plate body 401 to reset, so that the cover plate body 401 re-closes the bottom opening of the unloading hopper 3. The output end of hydraulic cylinder 603 retracts, causing the extension plate 602 to be retracted back into the bottom of the funnel car.
