Description

Technical Field

[0001] This utility model relates to the field of ballast construction technology, specifically to an automatic quantitative and precise ballast application device for ballast construction. Background Technology

[0002] Ballast is an important component of railway track structure. It refers to a layer of crushed stone or pebbles laid on the railway subgrade and under the sleepers. It plays a role in supporting the sleepers, distributing train loads, providing elasticity, drainage, and stabilizing the geometry of the track. The quantitative ballast spreading device is a special equipment designed for railway ballast laying operations.

[0003] However, some existing ballast-spreading devices cannot adjust the spreading position during use, resulting in inaccurate ballast discharge. This makes it difficult to disperse the ballast before discharge, and the discharged ballast tends to pile up, requiring manual leveling by workers. This not only affects the accuracy of the spreading position but also increases the workload of workers, reduces the construction efficiency of the device, and affects its applicability. Utility Model Content

[0004] The purpose of this invention is to provide an automatic quantitative and precise ballast application device for ballast construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic quantitative and precise spreading device for ballast construction, comprising a power mechanism and a storage bin installed on its surface, and further comprising:

[0006] A discharge mechanism is installed at the bottom of the storage box. An adjustment mechanism is installed on the surface of the discharge mechanism. A guide shell is installed on the surface of the adjustment mechanism. A material distribution plate is fixedly connected to the inner cavity of the guide shell. A discharge trough is opened at the bottom of the inner cavity of the guide shell.

[0007] Guide rails are fixed to both sides of the guide housing. A movable frame is slidably connected to the surface of the guide rail. A blocking frame is fixedly connected to the bottom of the movable frame. A positioning mechanism is provided at the bottom of the blocking frame.

[0008] Preferably, the adjusting mechanism includes a rotating rod that rotates at the bottom of the discharge mechanism housing and worm gears fixed at both ends thereto, with a worm engaged on one side of the worm gears.

[0009] Preferably, the positioning mechanism includes a movable plate disposed at the bottom of the blocking frame and positioning rods fixed at two points on its top, and a tension spring is fixedly connected to the surface of the movable plate.

[0010] Preferably, a guide rod is slidably connected to the inner cavity of the movable plate, and one end of the guide rod is fixedly connected to the bottom of the blocking frame.

[0012] Preferably, one side of the guide shell has an inclined structure design, and there are several material distribution plates, all of which are used in conjunction with the guide shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention allows for adjustment of the guide shell's angle through a regulating mechanism, thereby changing the guide shell's discharge position on the ballast and improving the accuracy of the ballast's position. Furthermore, the cooperation between the guide shell and the distribution plate allows the ballast to be dispersed before discharge, effectively increasing the area and uniformity of the ballast's application and enhancing its applicability. Additionally, the blocking frame removes obstruction to the discharge chute, allowing the ballast to be discharged from a single point, further improving the device's applicability and solving the problems of poor ballast application accuracy and limited applicability in existing devices.

[0020] 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.

[0021] Please see Figure 1-4As shown, an automatic quantitative and precise ballast spreading device for ballast construction includes a power mechanism 1. A storage tank 2 is mounted on the surface of the power mechanism 1, which stores ballast for subsequent construction. The power mechanism 1 also moves the storage tank 2 for ease of use. A discharge mechanism 3 is mounted at the bottom of the storage tank 2, which discharges the ballast from the tank. An adjustment mechanism 4 is mounted on the surface of the discharge mechanism 3, and a guide shell 5 is mounted on the surface of the adjustment mechanism 4. The angle of the guide shell 5 can be adjusted by the adjustment mechanism 4, allowing the guide shell 5 to discharge the ballast. In different locations, the applicability of the device is improved. The inner cavity of the guide shell 5 is fixedly connected to the material distribution plate 6. One side of the guide shell 5 has an inclined structure design. There are several material distribution plates 6, all of which are used in conjunction with the guide shell 5. Under this action, the ballast discharged by the discharge mechanism 3 can be guided by the cooperation of the guide shell 5 and the material distribution plate 6, so that the ballast can be discharged evenly. This makes the ballast laying position of the device more accurate and reduces the situation where the ballast accumulates together and affects the spreading effect, effectively improving the applicability of the device. The outer shell of the discharge mechanism 3 has a positioning groove 13. The inner cavity of the positioning groove 13 is slidably connected to the locking rod 12 for locking. One side of rod 12 is fixedly connected to the inner wall of guide shell 5. Under this action, the position of guide shell 5 can be more accurately adjusted by adjustment mechanism 4 through the cooperation of locking rod 12 and positioning groove 13, reducing the easy occurrence of positional deviation of guide shell 5 and effectively improving the stability of guide shell 5. A discharge groove 7 is opened at the bottom of the inner cavity of guide shell 5. Under the action of discharge groove 7, it is more convenient when the device needs to discharge ballast at a fixed point, effectively improving the applicability of the device. Guide rails 8 are fixedly connected to both sides of guide shell 5. Movable frame 9 is slidably connected to the surface of guide rail 8. A blocking frame 10 is fixedly connected to the bottom of movable frame 9. The device can block the discharge chute 7, preventing ballast from easily being discharged from it when not in use, thus effectively improving the applicability of the device. The position of the blocking frame 10 can be easily adjusted through the cooperation of the guide rail 8 and the movable frame 9, so that the blocking frame 10 no longer blocks the discharge chute 7. The cross-sectional shape of the guide rail 8 is a T-shaped structure design, which prevents the movable frame 9 from easily disengaging from the guide rail 8. The bottom of the blocking frame 10 is provided with a positioning mechanism 11, which can limit the blocking frame 10 through the cooperation of the movable frame 9, preventing it from easily shifting its position and affecting the blocking effect on the ballast.

[0022] The adjusting mechanism 4 includes a rotating rod 41 that rotates at the bottom of the outer shell of the discharge mechanism 3. Both ends of the rotating rod 41 extend through the outer side of the guide shell 5 and are fixedly connected to the inner wall of the through-hole. Both ends of the rotating rod 41 are fixedly connected to worm gears 42. A worm 43 meshes with one side of the worm gears 42. The worm 43 is connected to the surface of the discharge mechanism 3 through a rotating seat. Under this action, the worm 43 can be supported. Under this action, the worm gears 42 can be rotated by rotating the worm 43 to drive the rotating rod 41 to rotate, thereby adjusting the tilt angle of the guide shell 5. This facilitates the adjustment of the discharge port position of the guide shell 5, thereby improving the applicability of the device.

[0023] The positioning mechanism 11 includes a movable plate 111 disposed at the bottom of the blocking frame 10. Positioning rods 112 are fixedly connected to two points on the top of the movable plate 111. The other end of each positioning rod 112 penetrates into the interior of the movable frame 9 and is slidably connected to the inner wall of its penetration point. A tension spring 113 is fixedly connected to the surface of the movable plate 111. The other end of the tension spring 113 is fixedly connected to the bottom of the blocking frame 10. Under this action, the positioning rods 112 can be embedded into the interior of the movable frame 9 with the cooperation of the tension spring 113, thereby limiting the movement of the movable frame 9 and preventing it from easily moving and affecting the blocking mechanism. The stability of the position of the baffle 10 is ensured. When the baffle 10 no longer blocks the discharge chute 7, the positioning rod 112 will contact the side of the guide rail 8, thereby blocking the baffle 10 through the positioning rod 112. The inner cavity of the moving plate 111 is slidably connected to the guide rod 14. One end of the guide rod 14 is fixedly connected to the bottom of the baffle 10. Under this action, the moving plate 111 can be guided by the guide rod 14 when it moves, so that it can be more stable when it moves, and avoid the moving plate 111 being unstable when it moves, which would affect the limiting effect on the baffle 10.

[0024] It is worth noting that the technical features such as the power mechanism 1, the storage box 2, and the discharge mechanism 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] Working principle: First, the ballast to be sprayed is placed inside the storage box 2. Then, the device is moved to the desired spraying position. Next, the operator rotates the worm gear 43 so that the worm wheel 42 adjusts the angle of the guide shell 5 via the rotating rod 41, allowing the guide shell 5 to spray to different positions. After adjustment, the power mechanism 1 and the discharge mechanism 3 are activated. The device moves under the action of the power mechanism 1, and the ballast is discharged into the interior of the guide shell 5 under the action of the discharge mechanism 3. The separation of the material distribution plate 6 ensures that the ballast is evenly spread, thereby increasing the area of ​​ballast spraying and effectively improving the accuracy of ballast spraying. When fixed-point spraying is required, the moving plate 111 can be pulled so that the positioning rod 112 no longer contacts the guide rail 8. Then, the position of the blocking frame 10 is adjusted so that the ballast can be discharged from the discharge chute 7, enabling the device to perform fixed-point spraying and effectively improving the applicability of the device.
