Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ballast paving, and in particular relates to a ballast uniform paving device with a screening function. Background Art
[0002] In railway construction, ballast is an important material for laying tracks, and its quality directly affects the stability and service life of the tracks. Traditional ballast laying is mostly done manually, which is labor-intensive, inefficient, and difficult to ensure uniform ballast laying. In order to solve these problems, modern railway construction has gradually adopted mechanized and automated ballast uniform paving equipment. Although modern ballast uniform paving equipment has made significant progress in improving laying quality and efficiency, there are still some problems due to the lack of material screening structure. Specifically, ballast paving equipment without a material screening structure may lay large pieces of material directly on the track during the laying process, resulting in excessive gaps between materials. Utility Model Content
[0003] In order to overcome the problem that the existing ballast paving equipment has no material screening structure, large pieces of material are directly laid, resulting in too large gaps between track laying materials.

[0005] Preferably, through the setting of the screening component, the material is fed into the interior of the screen from the feeding port, and the driving motor drives the screen to rotate, so that the material passes through the holes of the screen to complete the screening, and finally the screened material falls into the discharge hopper and is discharged downward to complete the material laying, which solves the problem of existing ballast paving equipment, because it has no material screening structure, resulting in large pieces of material being directly laid, which leads to excessive gaps between track laying materials.
[0006] Preferably, the screening assembly comprises a first bearing disc, a driving motor, a screen, a second bearing disc, and a feeding port; a screen is arranged inside the feeding hopper.
[0007] Preferably, a first bearing disk and a second bearing disk are respectively provided at the front and rear ends of the screen, and the first bearing disk and the second bearing disk are rotatably connected to the ball bearing of the first bearing disk.
[0008] Preferably, a feeding port is provided at the rear end of the second bearing disk, and the feeding port is fixedly connected to the second bearing disk; the outer walls of the first bearing disk and the second bearing disk are fixedly connected to the inner wall of the feeding hopper.
[0009] Preferably, a driving motor is arranged in front of the first bearing disk, and the output end of the driving motor is connected to the screen transmission. Through the setting of the screening component, the material is fed into the interior of the screen from the feeding port, and the driving motor drives the screen to rotate, so that the material passes through the holes of the screen to complete the screening. Finally, the screened material falls into the discharge hopper and is discharged downward to complete the material laying.
[0010] Preferably, the pressing assembly includes a pressing cylinder and a pressing plate; a pressing plate is arranged on the inner side of the frame; a pressing cylinder is arranged above the pressing plate, and the output end of the pressing cylinder is connected to the lifting transmission of the pressing plate, and the outer shell of the pressing cylinder is fixedly connected to the inner wall of the frame, and the pressing cylinder of the pressing assembly drives the pressing plate to press downward, thereby facilitating the downward pressing and leveling of the material laying.
[0011] Preferably, the vibration assembly includes a cylinder lifting bracket and a vibration rod array; a vibration rod array is arranged on one side of the downward pressure cylinder, and a cylinder lifting bracket is arranged above both ends of the vibration rod array, and the cylinder lifting bracket is connected to the lifting control of the vibration rod array, and the outer shell of the cylinder lifting bracket is fixedly connected to the inner side of the frame, and the cylinder lifting bracket of the vibration assembly drives the vibration rod array to insert it into the material pair for vibration, thereby effectively reducing the gap spacing between particles of the material pile and improving stability.
[0012] Beneficial effects of the utility model:
[0013] 1. The existing ballast paving equipment has no material screening structure, which causes large pieces of material to be laid directly, resulting in too large gaps between track laying materials. Through the setting of the screening component, the material is put into the screen from the feeding port, and the motor drives the screen to rotate, so that the material passes through the holes of the screen to complete the screening. Finally, the screened material falls into the discharge hopper and is discharged downward to complete the material laying. This solves the problem that the existing ballast paving equipment has no material screening structure, which causes large pieces of material to be laid directly, resulting in too large gaps between track laying materials.
[0014] 2. Through the setting of the down-pressing component and the vibration component, the down-pressing cylinder of the down-pressing component drives the down-pressing plate to press down, so as to facilitate the down-pressing and leveling of the material laying; the cylinder lifting bracket of the vibration component drives the vibrating rod array to insert it into the material for vibration, thereby effectively reducing the gap spacing between the particles of the material pile and improving stability.
