[0032] Reference Figure 1A linear screen includes a frame 1 arranged horizontally on the ground, and an inclined sieve plate 2 is installed on the frame 1. The sieve plate 2 is inclined, and an excitation source (not shown in the figure) for vibrating and screening the material on the sieve plate 2 is installed at the bottom of the frame 1. A mounting plate 11 is also fixed to the upper surface of the frame 1, and a feed port 111 is opened on the mounting plate 11. The sieve plate 2 is gradually inclined downward from the side close to the feed port 111 to the side away from the feed port 111. Two discharge ports 12 are installed on the side of the frame 1 away from the feed port 111. The two discharge ports 12 flow out the material on the upper and lower sides of the sieve plate 2 respectively, and a bulking mechanism 3 is installed on the side of the frame 1 close to the feed port 111. The material falling from the feed port 111 onto the sieve plate 2 can evenly disperse the bulking mechanism 3, reduce the accumulation of materials, and improve the screening efficiency.

[0033] The bulk material mechanism 3 includes a driving assembly 31 and an adjusting assembly 32. The driving assembly 31 includes a mounting rod 311 horizontally mounted on the upper side of the frame 1. The length direction of the mounting rod 311 is perpendicular to the length direction of the sieve plate 2, and the mounting rod 311 is located on the side of the frame 1 close to the feed port 111. The end of the mounting rod 311 is fixedly connected to the frame 1 through the adjusting assembly 32. The middle section of the mounting rod 311 is vertically fixed with a motor 312. The output end of the motor 312 is fixed with a rotating rod 313. The rotating rod 313 passes through the mounting rod 311 and faces the direction close to the sieve plate 2. The sieve plate 2 is provided with a plurality of slurry collecting rods 314, each of which is provided with a plurality of slurry collecting rods 316. The sieve plate 2 is provided with a plurality of slurry collecting rods 317, and the sieve plate 2 is provided with a plurality of slurry collecting rods 318.

Both ends of the reinforcing rod 315 are fixed to the bulking bars 314, and the reinforcing rod 315 is located on the side of the bulking bars 314 close to the rotating rod 313, thereby improving the stability of the bulking bars 314 during bulking and reducing deformation of the bulking bars 314.

[0035] Reference Figure 1 and Figure 2 There are two adjustment components 32, and the two adjustment components 32 are symmetrically arranged about the mounting rod 311. Each adjustment component 32 includes an adjustment rod 321, and the adjustment rod 321 is vertically fixed to the end of the mounting rod 311, and the adjustment rod 321 extends toward the direction close to the frame 1. Sleeves 322 are fixed on both side walls of the frame 1, and the adjustment rod 321 and the sleeve 322 are aligned and plugged into each other.

A plurality of fixing openings 3211 are provided on the side of each adjusting rod 321 close to the fixing column 323. The plurality of fixing openings 3211 are spaced apart along the length direction of the adjusting rod 321, and the adjusting rod 321 can slide toward the direction close to the fixing column 323 so that the fixing openings 3211 and the fixing column 323 are engaged with each other, thereby pre-fixing the insertion depth of the adjusting rod 321 in the sleeve 322.

[0037] A threaded hole 3221 is further provided on the side wall of the sleeve 322 away from the fixing column 323. The threaded hole 3221 and the fixing column 323 are arranged relative to each other. A bolt 324 is threadedly connected in the threaded hole 3221. The bolt 324 passes through the side wall of the sleeve 322 and is tightly pressed against the adjusting rod 321, thereby fixing the position of the adjusting rod 321.

[0038] The implementation principle of a linear screen in the embodiment of the present application is:

[0039] When the material is screened, the material falls from the feed port 111 onto the screen plate 2. The screen plate 2 vibrates to cause the material to tilt and slide downward, and finally the material flows out from the discharge port 12 to achieve material screening. The bulking rod 314 rotates under the drive of the driving component 31, so that the material accumulated near the feed port 111 is dispersed by the bulking rod 314. The adjusting component 32 adjusts the distance between the bulking rod 314 and the screen plate 2, so as to better disperse the material and improve the screening efficiency.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
