[0004] However, the above-mentioned patent still has the following shortcomings in actual use: some sand will remain on the filter plate of the patent. Once this sand solidifies, it will affect the filtration of the filter plate and thus affect the entire sand screening operation. Utility Model Content

[0005] The purpose of this utility model is to provide a sand screening device for construction, in order to solve the problem mentioned in the background art that some sand will remain on the filter plate, and once the sand solidifies, it will affect the filtration of the filter plate, and thus affect the entire sand screening operation.

[0006] The technical solution of this utility model is:

[0007] A sand screening device for construction includes a base plate, a sand screening box, a sand screening cylinder, a feeding hopper, a stirring component, a vibrating plate, a filter plate, a linkage component, a conveying component, two fixed blocks, four support blocks, and four springs. The base plate has four supports on its top. The sand screening box is inclinedly mounted on the four supports. The two fixed blocks are symmetrically arranged inside the sand screening box. The sand screening cylinder is mounted on the two fixed blocks. The feeding hopper is mounted on the top of the sand screening box, and its bottom end is connected to the inside of the sand screening cylinder. The stirring component is mounted inside the sand screening cylinder, and one end of the stirring component extends to the outside of the sand screening box. The four support blocks are rectangularly distributed at the bottom of the inside of the sand screening box. The four springs are respectively located at the bottom of the four support blocks. The vibrating plate is mounted on the bottom ends of the four springs. The filter plate is mounted on the vibrating plate. The linkage component is mounted on the top of the vibrating plate, and its top end is in transmission cooperation with the stirring component. The conveying component is mounted on the top of the base plate, and is located below the filter plate.

[0008] Furthermore, the agitation assembly includes an agitation shaft, an agitation motor, and multiple agitation rods. The agitation shaft is rotatably installed inside the sand screening cylinder, and one end of the agitation shaft extends to the outside of the sand screening box. The multiple agitation rods are equally spaced on the agitation shaft. The agitation motor is horizontally installed on the outer wall of the sand screening box, and the output shaft of the agitation motor is connected to the agitation shaft.

[0009] Furthermore, the linkage assembly includes a mounting base, an abutting wheel, a linkage shaft, a linkage cam, a driving wheel, a driven wheel, and a belt. The mounting base is disposed on the top of the vibrating plate. The abutting wheel is rotatably mounted inside the mounting base. The linkage shaft is rotatably mounted on the inner wall of the sand screening box. The linkage cam is mounted on the linkage shaft, and the bottom end of the linkage cam abuts against the top end of the abutting wheel. The driving wheel is mounted on the agitation shaft. The driven wheel is mounted on the linkage shaft. The belt is sleeved on the outside of the driving wheel and the driven wheel.

[0011] Furthermore, the sand screening cylinder has multiple first screen holes, and the filter plate has multiple second screen holes, the diameter of the second screen holes being smaller than the diameter of the first screen holes.

[0012] Furthermore, a collection box is provided on the top of the base plate.

[0013] This utility model provides an improved sand screening device for construction, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this invention uses a feeding hopper to feed sand into a sand screening cylinder. Then, an agitator works to stir the sand in the screening cylinder, leaving impurities inside. The sand falls out of the screening cylinder and enters the filter plate. While the agitator is working, it drives a linkage component, which in turn drives a vibrating plate to vibrate back and forth on four springs. This causes the filter plate to vibrate synchronously to screen the sand. Fine sand falls through the filter plate onto a conveying component, while coarse sand rolls off the filter plate and is collected. The filter plate vibrates continuously, so the sand will not remain or solidify on the filter plate, thus not affecting the entire sand screening process.

[0015] Secondly, when the agitator shaft rotates, the agitator shaft drives the drive wheel to rotate. The drive wheel drives the driven wheel and the linkage shaft to rotate via a belt. In turn, the linkage shaft drives the linkage cam to rotate. The linkage cam then drives the vibrating plate to reciprocate on four springs via a contact wheel. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved sand screening device for construction, such as... Figures 1-4 As shown, the system includes a base plate 1, a sand screening box 2, a sand screening cylinder 3, a feeding hopper 4, a stirring assembly 5, a vibrating plate 6, a filter plate 61, a linkage assembly 7, a conveying assembly 8, two fixed blocks 9, four support blocks 91, and four springs 92. The base plate 1 has four supports 11 on its top. The sand screening box 2 is inclinedly mounted on the four supports 11. The two fixed blocks 9 are symmetrically arranged inside the sand screening box 2. The sand screening cylinder 3 is mounted on the two fixed blocks 9. The feeding hopper 4 is mounted on the top of the sand screening box 2, and its bottom end is connected to the inside of the sand screening cylinder 3. The stirring assembly 5 is mounted inside the sand screening cylinder 3, and one end of the stirring assembly 5 extends to the outside of the sand screening box 2. The four support blocks 91 are rectangularly distributed at the bottom of the inside of the sand screening box 2. The four springs 92 are respectively located at the bottom of the four support blocks 91. The vibrating plate 6 is mounted on the bottom of the four springs 92. The filter plate 61 is mounted on the bottom of the four springs 92. On the vibrating plate 6, the linkage component 7 is installed on the top of the vibrating plate 6, and the top of the linkage component 7 is driven by the stirring component 5. The conveying component 8 is installed on the top of the base plate 1 and is located below the filter plate 61. Sand is fed into the sand screening cylinder 3 by using the feeding hopper 4. Then the stirring component 5 works to stir the sand in the sand screening cylinder 3. Impurities remain in the sand screening cylinder 3, and the sand falls out of the sand screening cylinder 3 and enters the filter plate 61. While the stirring component 5 is working, it drives the linkage component 7 to work. The linkage component 7 drives the vibrating plate 6 to vibrate back and forth on the four springs 92. Then the filter plate 61 vibrates synchronously to vibrate and screen the sand. Fine sand falls into the conveying component 8 through the filter plate 61, and coarse sand rolls down from the filter plate 61 and is collected. The filter plate 61 vibrates continuously, and the sand will not remain and solidify on the filter plate 61, thus not affecting the entire sand screening work. Finally, the conveying component 8 works to convey the fine sand.

[0025] Specifically, the agitation assembly 5 includes an agitation shaft 51, an agitation motor 52, and multiple agitation rods 53. The agitation shaft 51 is rotatably installed inside the sand screening cylinder 3, and one end of the agitation shaft 51 extends to the outside of the sand screening box 2. The multiple agitation rods 53 are equally spaced on the agitation shaft 51. The agitation motor 52 is horizontally installed on the outer wall of the sand screening box 2, and the output shaft of the agitation motor 52 is connected to the agitation shaft 51. The agitation motor 52 drives the agitation shaft 51 and the multiple agitation rods 53 to rotate, and the rotation of the multiple agitation rods 53 agitates and screens the sand inside the sand screening cylinder 3.

[0026] Specifically, the linkage assembly 7 includes a mounting base 71, an abutment wheel 72, a linkage shaft 73, a linkage cam 74, a drive wheel 75, a driven wheel 76, and a belt 77. The mounting base 71 is located on top of the vibrating plate 6. The abutment wheel 72 is rotatably mounted inside the mounting base 71. The linkage shaft 73 is rotatably mounted on the inner wall of the sand screening box 2. The linkage cam 74 is mounted on the linkage shaft 73, and the bottom end of the linkage cam 74 abuts against the top end of the abutment wheel 72. The drive wheel 75 is mounted on the agitation shaft 51. The driven wheel 76 is mounted on the linkage shaft 73. The belt 77 is sleeved on the outside of the drive wheel 75 and the driven wheel 76. When the agitation shaft 51 rotates, it drives the drive wheel 75 to rotate. The drive wheel 75 uses the belt 77 to drive the driven wheel 76 and the linkage shaft 73 to rotate. In turn, the linkage shaft 73 drives the linkage cam 74 to rotate. The linkage cam 74 then uses the abutment wheel 72 to drive the vibrating plate 6 to reciprocate on the four springs 92.

[0027] Specifically, the conveying assembly 8 includes a first conveying frame 81, a second conveying frame 82, a drive roller 83, a driven roller 84, a conveyor belt 85, and a conveying motor 86. The first conveying frame 81 and the second conveying frame 82 are spaced apart on the top of the base plate 1. The drive roller 83 and the driven roller 84 are rotatably mounted inside the first conveying frame 81 and the second conveying frame 82, respectively. The conveyor belt 85 is sleeved on the outside of the drive roller 83 and the driven roller 84. The conveying motor 86 is horizontally mounted on the outer wall of the first conveying frame 81, and the output shaft of the conveying motor 86 is connected to the drive roller 83. The operation of the conveying motor 86 drives the drive roller 83 to rotate, and the drive roller 83 and the driven roller 84 cooperate to drive the conveyor belt 85 to rotate. The rotation of the conveyor belt 85 conveys the fine sand that falls into it.

[0028] Specifically, the sand screening cylinder 3 has multiple first screen holes 31, and the filter plate 61 has multiple second screen holes 62. The diameter of the second screen holes 62 is smaller than the diameter of the first screen holes 31. Sand with a volume smaller than the first screen holes 31 falls out of the sand screening cylinder 3, and fine sand with a volume smaller than the second screen holes 62 falls off the filter plate 61.

[0029] Specifically, a collection box 12 is provided on the top of the base plate 1; the collection box 12 collects the coarse sand that rolls down from the filter plate 61.
