DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0021] like Figures 1 to 4As shown, a telescopic ballast screening machine includes a bracket 101, a hopper 102 is fixed above the bracket 101, a vibrating screening plate 103 is arranged above the hopper 102, a support wheel 104 for assisting movement is installed at the lower end of the bracket 101, and a conveying assembly for conveying the screened material arranged on the bracket 101, the conveying assembly includes a conveyor 201 installed on the bracket 101, and a conveyor 201 is installed on the conveyor 201 for driving the conveyor 201. The conveyor 201 is a telescopic conveyor 201 with a length that can be extended. A telescopic motor 203 for controlling the length of the conveyor 201 is installed on the conveyor 201. Two sets of chassis connecting seats 6 are arranged on one side of the bracket 101. The chassis connecting seats 6 are rotatably connected to one side of the excavator chassis through a pin shaft. A telescopic component for adjusting the distance between the connecting seat 6 and the bracket 101 and an adjusting member for adjusting the angle of the bracket 101 are arranged between the connecting seat 6 and the bracket 101.

[0022] When the ballast screening machine is in use, the dirty ballast under the railway track is screened through the cooperation of the conveying component with the vibrating screening plate 103 and the hopper 102. During the screening operation, the conveyor 201 is extended and retracted, and the bracket 101 is moved and steered, so that the ballast screening machine can more flexibly screen the dirty ballast under the railway track.

[0023] The telescopic assembly includes two groups of sleeves 701, which are rotatably connected to the two groups of connecting seats 6 through pins. Slides 702 are slidably connected to the two groups of sleeves 701, and one end of the slide 702 is fixed to one side of the bracket 101. A connecting frame 703 is fixed between the two groups of sleeves 701. A first oil cylinder 704 is rotatably installed on the connecting frame 703 through a pin, and the output end of the first oil cylinder 704 is fixed to one side of the bracket 101; during the screening operation, the bracket 101 is driven to move toward or away from the connecting seat 6 through the drive of the first oil cylinder 704 and the sliding connection between the two groups of sleeves 701 and the slide 702. Through the movement of the bracket 101, the conveyor 201 on the bracket 101 can transport the screened materials to different positions on both sides of the railway track.

[0024] The adjusting part is a second oil cylinder 8, and the end of the second oil cylinder 8 is rotatably connected to the connecting seat 6 through a pin shaft, and the output end of the second oil cylinder 8 is rotatably connected to the outer side of the sleeve 701; through the telescopic drive of the second oil cylinder 8, one end of the sleeve 701 rotates on the connecting seat 6, and through the rotation of the sleeve 701, the use angle of the bracket 101 is adjusted to meet the requirements of the horizontal level of the screening system during construction and non-interference when transporting on and off the cart.

[0025] The hopper 102 is a trumpet-shaped sloped structure with a wide upper portion and a narrow lower portion. The top of the hopper 102 is connected to the vibrating screening plate 103 via a rubber block 3; the rubber block 3 is used to perform a buffering operation on the vibrating screening plate 103 during the screening process.

[0026] The lower opening of the hopper 102 is kept at a corresponding distance from the conveyor 201 and is surrounded by a flexible enclosure 4; the flexible enclosure 4 prevents the conveyor belt from interfering with the hopper 102 and preventing the conveyed materials from overflowing.

[0027] Two ballast retaining plates 5 with adjustable width arranged in an "eight" shape are slidably connected to the upper part of the vibrating screening plate 103; the ballast retaining plates 5 can be used to evenly guide the sliding ballast.

[0028] When the ballast screening machine is in use, the two sets of connecting seats 6 are rotatably connected to one side of the excavator chassis through the pin shaft. After the connection is completed, the ballast screening machine is driven to move by the movement of the excavator chassis, so that the ballast screening machine is above the railway track. After the movement is completed, the dirty ballast under the railway track is grabbed by the excavator chassis and thrown toward the vibrating screening plate 103. The fallen dirty ballast is vibrated and screened by the vibrating screening plate 103. During the screening process, the ballast passes through one side of the vibrating screening plate 103 and falls onto the roadbed. The screened soil and fine sand fall onto the conveyor 201, and the screened soil and fine sand are transported toward both sides of the track by the conveyor 201, completing the screening operation of the dirty ballast under the railway track.

[0029] During the screening operation, the telescopic motor 203 on the conveyor 201 drives the conveyor 201 to adjust the use length of the conveyor 201. By adjusting the use length of the conveyor 201, the extended state meets the requirements of conveying fine sand outside the working area during construction, and the retracted state meets the requirements of not exceeding the width during transportation;

[0030] During the screening operation, the bracket 101 is driven to move toward or away from the connecting seat 6 through the drive of the first cylinder 704 and the sliding connection between the two sets of sleeves 701 and the slide 702. The movement of the bracket 101 facilitates the conveyor 201 on the bracket 101 to transport the screened materials to different positions on both sides of the railway track. During the screening operation, the second cylinder 8 is driven to extend and retract, and one end of the sleeve 701 rotates on the connecting seat 6. The rotation of the sleeve 701 adjusts the use angle of the bracket 101 to meet the requirements of the horizontal level of the screening system during construction and non-interference when transporting the upper and lower carts, which further facilitates the ballast screening machine to more flexibly screen the dirty ballast under the railway track.
