In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0031] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0033] Reference Figures 1-5 The present application provides an aluminum alloy specific gravity machine screen bed, which has a feed end 370 and a discharge end 380, and comprises a wooden support beam 330. The wooden support beam 330 has a plurality of wooden support beams 330, which are arranged in the metal frame 310. The wooden support beams 330 are distributed along the feed end 370 to the discharge end 380 in sequence. The L-shaped connecting piece 360 has a first side 361 and a second side 362 perpendicular to each other. The first side 361 is arranged on the metal frame 310, and the second side 362 is arranged on the wooden support beam 330.

[0034] In this embodiment, the stable connection between the wooden support beam 330 and the metal frame 310 is achieved by the L-shaped connecting piece 360. The use of the L-shaped connecting piece 360 instead of the traditional glue fixing method greatly simplifies the installation process and improves the assembly efficiency. Secondly, it avoids opening installation holes on the wooden main beam, thereby reducing the damage to the main beam structure and prolonging its service life. Furthermore, the combination of the metal frame 310 and the wooden support beam 330 can reduce the overall weight while ensuring a certain strength.

[0035] It should be further pointed out that the metal is preferably an aluminum alloy.

[0036] Further, it further comprises a metal frame 310, a metal edge frame 320 is arranged on the metal frame 310; a uniform wind plate 350 is arranged on the metal frame 310, and the uniform wind plate 350 is located between the metal frame 310 and the metal edge frame 320, and the wooden support beam 330 is used to support the uniform wind plate 350; a screen mesh 340 is arranged on the metal frame 310, and the screen mesh 340 is located between the uniform wind plate 350 and the metal edge frame 320, and the screen mesh 340 and the metal frame 310 form a screening space.

[0037] In this embodiment, in actual operation, the metal edge frame 320 surrounds the periphery of the metal frame 310. When the material is sieved on the screen mesh 340, the metal edge frame 320 effectively blocks the material from sliding out from the side of the screen bed. The reasonable layout of the uniform wind plate 350 helps to uniformly distribute the wind force, improving the screening effect and efficiency. Furthermore, the support of the wooden support beam 330 to the uniform wind plate 350 ensures the stability of the uniform wind plate 350, so that it can better play its role. The holes on the screen mesh 340 can allow the wind to pass from below, but the material will not fall from the holes on the screen mesh 340, ensuring that the material can be discharged from the discharge end 380.

[0038] Further, the first edge 361 has a plurality of first mounting holes 3611, and the second edge 362 has a plurality of second mounting holes 3621, and the first mounting holes 3611 and the second mounting holes 3621 are used for the screw to pass through.

[0039] In this embodiment, the screw is fixed by passing through the mounting hole, and the connection method is simple and reliable, easy to operate and maintain. Secondly, the setting of multiple mounting holes increases the stability of the connection, so that the connecting piece can withstand greater force and vibration, ensuring the stability of the screen bed structure. Furthermore, this detachable connection method facilitates the replacement and maintenance of parts when needed, reducing the use cost.

[0040] It should be further pointed out that the wooden support beam 330 can be replaced by iron nails to further reduce the cost.

[0041] Further, the baffle 391 is arranged on the uniform air plate 350, and the baffle 391 is arranged between the uniform air plate 350 and the screen 340.

[0042] In the embodiment, the baffle 391 can guide the air between the uniform air plate 350 and the screen 340 to change the direction to the direction perpendicular to the feeding end 370 to the discharging end 380 during the operation.

[0043] Further, the fixed seat 392 is arranged outside the metal frame 310, and the metal frame 310 is fixedly connected with the vibrating seat of the screening machine through the fixed seat 392.

[0044] In the embodiment, the specific connection structure and the fixed mode on the fixed seat 392 can ensure that the screen bed is stably installed on the vibrating seat and can normally work with the vibration of the vibrating seat.

[0045] The connection between the fixed seat 392 and the vibrating seat of the screening machine can adopt the bolt connection mode, which is not only firm but also convenient to disassemble.

[0046] Further, the screen 340 is a woven mesh.

[0047] In the embodiment, the woven mesh usually has good flexibility and elasticity, can adapt to the vibration of the screen bed and the impact of the material, and is not easy to be damaged.

[0048] It should be noted that the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit it, and although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical scheme of the utility model, and all of them should be covered in the claim range of the utility model.
