After the ballast particles are screened step by step, particles of different gradations can be obtained, and these particles can be used in railway construction. This can not only avoid material waste, but also improve material utilization and reduce engineering costs. In the fields of mining, stone processing, etc., the ballast waste generated can be screened by a ballast size graded screener, and particles of different sizes can be classified and recycled. This can not only reduce the discharge of waste, but also convert waste into valuable resources and promote the recycling of resources. However, the traditional screening equipment is too large in size, which does not conform to the characteristics of road construction that is built and moved at the same time. At the same time, the traditional equipment can only screen one size of ballast at a time, and the screen replacement process requires downtime, which affects the project progress.

[0021] Please refer to the attached Figure 1 To Attachment Figure 4 A ballast grading screen according to the present invention is described.

[0022] like Figure 1 and Figure 2As shown, a ballast grading screener in the present invention includes a casing structure 1, a feeding structure 2, a screening structure 3, and the casing structure 1 includes a feeding port 11, a storage box 12, an angle adjustment gear 13, a motor bracket 14, a rotating shaft limiting column 15, and a barrel 16; the feeding port 11 is arranged at the storage box 12. The storage box 12 is arranged at the rear side of the device, and the storage box 12 and the barrel 16 are connected. The angle adjustment gear 13 is installed at the rear side of the barrel 16, and the angle of the barrel 16 can be adjusted using an external motor angle adjustment gear. The motor bracket 14 is installed at the front side of the barrel 16, and the motor bracket 14 is used to install the motor. The rotating shaft limiting column 15 is arranged on the inner side of the barrel 16.

[0023] like Figure 1 and Figure 3 As shown, the feeding structure 2 includes a rotating shaft 21, a pushing blade 22, a transmission belt 23, a motor 24, and a transmission wheel 25; the rotating shaft 21 is installed in the rotating shaft limiting column 15, and a transmission belt 23 is installed at one end of the rotating shaft 21. The pushing blade 22 is installed on the rotating shaft 21. The transmission belt 23 is respectively installed on the rotating shaft 21 and the transmission wheel 25 for transmitting power. The motor 24 is installed on the motor bracket 14, and a transmission wheel 25 is installed at the power output end of the motor 24.

[0024] like Figure 1 and Figure 4 As shown, the screening structure 3 includes a bracket 31, a locking frame 32, a locker 33, an adjustable screen 34, a 22.4 mm sieve 35, a 31.5 mm sieve 36, a 40 mm sieve 37, a 50 mm sieve 38, and a 63 mm sieve 39; the bracket 31 is used for the receiving device, and the bracket 31 can lift the cylinder 16 to a certain height to facilitate the transportation of the screened ballast. The locking frame 32 is used to install the locker 33 and the adjustable screen 34. The locker 33 can be locked to limit the position of the adjustable screen 34. The 22.4 mm sieve 35, the 31.5 mm sieve 36, the 40 mm sieve 37, the 50 mm sieve 38, and the 63 mm sieve 39 are used to screen ballast of different grades to achieve the purpose of graded screening.

[0025] The working principle of the present invention is:

[0026] like Figures 1 to 4As shown, a ballast grading screener is used. When in use, unscreened ballast is first added to the storage box 12 through the feeding port 11. Then multiple screens 34 are installed and placed on the barrel 16 according to the required size. The handle of the screen is placed on the locking frame 32, and the screen is fixed with the lock 33. Next, the motor 24 is turned on, and the rotation of the motor 24 drives the shaft 21 to move. The movement of the shaft 21 drives the push blade 22 to rotate. The rotation of the push blade 22 pushes the storage box 12 to move in the barrel 16. Under the influence of gravity, the stored material will pass through the 22.4 mm sieve 35, 31.5 mm sieve 36, 40 mm sieve 37, 50 mm sieve 38, and 63 mm sieve 39 at the bottom of the barrel 16 step by step. At this time, the ballast of different grades will fall out of the barrel 16 to complete the screening.

[0027] The invention can not only meet the conventional ballast screening needs, but also screen ballast of different sizes at the same time, and the screening size can be adjusted without stopping the machine. Compared with the screener, this design has high screening efficiency and reduces labor costs.
