A material guiding assembly is arranged on the side of the hopper close to the screen. The material guiding assembly can uniformly lay the sand discharged from the hopper on the screen, so that the screen is uniformly stressed. The material guiding assembly comprises a material uniformizing spoon arranged between the hopper and the screen and used for receiving the sand falling from the hopper and uniformly spreading the sand on the screen, and a driving member arranged in the mounting frame and used for driving the material uniformizing spoon to reciprocatingly rotate.

[0006] In order to make the sand falling from the hopper fall on the material uniformizing spoon:
[0007] As a further improvement of the above technical scheme, the width of the material uniformizing spoon is greater than the sand feeding coverage area of the hopper.

[0013] As a further improvement of the above technical solution, the included angle between the bottom wall of the uniform material scoop and the side wall of the uniform material scoop close to the driving member is obtuse.
[0014] The improved sand screening device has the advantages that when the sand is guided to the uniform material scoop along the telescopic pipe, the sand slides along the bottom of the uniform material scoop to the screen, and the uniform distribution and smooth movement of the sand are promoted.
[0015] In order to enhance the stability and durability of the screen,
[0016] As a further improvement of the above technical solution, the screen is obliquely arranged, and the bottom wall of the screen is uniformly provided with a plurality of reinforcing rods.
[0017] The improved sand screening device has the advantages that the screen is obliquely arranged, the sand screening efficiency is improved, the sand falling on the screen slides along the surface of the screen by the gravity of the sand, the sand smaller than the aperture of the screen passes through the screen and falls on the guide plate below the screen, the guide plate is opposite to the oblique direction of the screen, the sand and the screened gravel are separated, the reinforcing rods are arranged at the bottom of the screen, and the stability and durability of the screen are enhanced.
[0018] In order to avoid that the reinforcing rods block the screen apertures and affect the sand screening effect,

[0028] In order to make the skilled in the art better understand the technical scheme of the utility model, the utility model is described in detail below in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.
[0029] As Figures 1-2 As shown in the figure, it is a sand screening device of prior art of the utility model, which mainly comprises a frame 2 for installing a screen 1 and a hopper 3 fixedly arranged at one end of the frame 2 and used for putting sand to the screen 1, the screen 1 is installed obliquely, which is arranged obliquely downward from the side close to the hopper 3 to the side away from the hopper 3, when screening sand, the sand is put onto the screen 1 along the hopper 3 through a feeding mechanism such as a conveyor belt, the sand smaller than the screen hole of the screen 1 passes through the screen 1, and the impurities in the sand slide along the screen 1, so that the sand and the impurities are separated, and the above is the introduction of the existing sand screening device.
[0030] From the above, the existing sand screening device has the following defects in use: because the sand contains stones of different sizes, the weight of the sand is increased, when the sand is conveyed by the conveying belt and directly falls on the screen 1, the pressure of the screen 1 is also increased, especially the screen 1 near the lower hopper 3, after a long time of sand screening operation, the screen 1 is deformed, especially for the screen 1 with a long size, because the stress is uneven, the degree of deformation of the screen 1 is increased, based on the above problems, the utility model adopts the following improvement mode to solve the problems.
[0031] As shown in Figures 3-6 , a sand screen for construction engineering construction, including the frame 2 for installing the screen 1 and the lower hopper 3 fixedly arranged at one end of the frame 2 and used for putting sand to the screen 1, the lower hopper 3 is provided with a material guiding assembly on the side close to the screen 1, through the material guiding assembly, the sand guided from the lower hopper 3 can be uniformly laid on the screen 1, so that the screen 1 is uniformly stressed, the material guiding assembly includes the uniform material spoon 4 arranged between the lower hopper 3 and the screen 1 and used for receiving the sand falling from the lower hopper 3 and uniformly spilling the sand on the screen 1 and the driving piece 5 arranged in the mounting frame and used for driving the uniform material spoon 4 to reciprocating rotate, through the arrangement of the material guiding assembly, the sand flowing from the lower hopper 3 can be uniformly and continuously laid on the screen 1, so that the screen 1 is balanced in stress, local overload is avoided, at the same time, the accumulation and blockage of the sand on the screen 1 are also avoided, which helps to speed up the sand screening speed and improve the sand screening efficiency.
[0032] Further, as shown in Figure 5 , the width of the uniform material spoon 4 is greater than the sand feeding coverage area of the lower hopper 3, so that the sand falling from the lower hopper 3 can all fall on the uniform material spoon 4, when the driving piece 5 drives the uniform material spoon 4 to reciprocating rotate counterclockwise and clockwise, the sand is uniformly spilled on the screen 1, which not only can reduce the weight of the sand once borne by the screen 1, but also can improve the efficiency of sand screening, the driving piece 5 can be a stepping motor or a servo motor, which can accurately control the angle of rotation of the uniform material spoon 4, so that the uniform material spoon 4 reciprocating rotates clockwise and counterclockwise within the width range of the screen 1, when the driving piece 5 does not operate, the uniform material spoon 4 is located directly below the lower hopper 3, when the driving piece 5 operates, the uniform material spoon 4 is driven to rotate clockwise by 45 degrees and then reset, and then rotates counterclockwise by 45 degrees, and so on.
[0033] Further, as shown in Figure 5 , the uniform material spoon 4 and the lower hopper 3 are provided with a telescopic pipe 6 arranged therebetween, so as to adjust the sand falling position and flow, the telescopic pipe 6 is similar to a bellows and is made of high-strength and flexible materials such as stainless steel, copper alloy and aluminum alloy, which can be length-adjusted and the direction of sand falling can be adjusted, the side close to the uniform material spoon 4 can move with the uniform material spoon 4, as shown in Figure 4As shown, one end of the bellows is connected with the uniform material spoon 4, and the other end is connected with the lower hopper 3, so as to facilitate the adjustment of the position of the sand falling on the uniform material spoon 4.
[0034] Further, as shown in the drawings, Figure 5 As shown, the included angle between the bottom wall of the uniform material spoon 4 and the side wall near one end of the driving member 5 is obtuse. When the sand is guided along the telescopic conduit 6 to the uniform material spoon 4, it slides along the bottom of the uniform material spoon 4 to the screen 1, which promotes the uniform distribution and smooth movement of the sand.
[0035] Further, as shown in the drawings, Figures 5-6 As shown, the screen 1 is installed obliquely, and the bottom wall of the screen 1 is uniformly provided with a plurality of reinforcing rods 7. The screen 1 is made of high-quality stainless steel such as 304 or 316L, which has high wear resistance and corrosion resistance and can resist the pressure and wear caused by the weight of the sand. In actual application, a plurality of screens 1 with different hole diameters can be arranged to facilitate the screening of sand with different particle sizes. The screen 1 is installed obliquely, which can improve the efficiency of sand screening. The sand put on the screen 1 slides along the surface of the screen 1 by gravity, and the sand smaller than the hole diameter of the screen 1 passes through the screen 1 and falls on the guide plate 8 below the screen 1, as shown in the drawings. Figure 5 As shown, the guide plate 8 is opposite to the inclined direction of the screen 1, which facilitates the separation of the sand and the screened gravel. Meanwhile, the reinforcing rods 7 are arranged at the bottom of the screen 1, which can enhance the stability and durability of the screen 1.
[0036] Further, as shown in the drawings, Figure 6 As shown, the size of the reinforcing rod 7 near the screen 1 is smaller than the size far from the screen 1. The reinforcing rod 7 can be conical or similar tapered structure. While supporting and reinforcing the screen 1, the reinforcing rod 7 reduces the contact area with the screen 1, avoiding the reinforcing rod 7 blocking the mesh of the screen 1 and affecting the sand screening effect.
