Summary of the Utility Model
[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that it is easy to have inconvenient shaking due to too much construction materials during the screening process, resulting in blockage.
[0006] To solve the above problems, the utility model provides a standard inspection sieve for construction project quality inspection, including a base. A bottom plate is fixedly connected to the top of the base. Support rods are symmetrically and fixedly connected to the top of the bottom plate.

A plurality of sub-sieves are detachably connected to the receiving box, and the sub-sieves are engaged with the receiving box through grooves. A lid is detachably connected to the top of the sub-sieve, and the limit plate abuts against the lid. A first clamping groove is drilled in the inner wall of the sub-sieve. A first clamping block is detachably connected to the first clamping groove. One end of the first clamping block away from the first clamping groove is fixedly connected to a spring. One end of the spring away from the first clamping block is fixedly connected to an elastic ball, and the elastic ball collides with the upper and lower ends of the sub-sieve.
[0007] In the above standard inspection sieve, it effectively achieves the effect of automatically dredging the sub-sieves in the standard inspection sieve during the screening process to avoid blockage.
[0008] As a further improvement of the present application, second clamping grooves are symmetrically drilled in the inner wall of the first clamping groove. Second clamping blocks corresponding to the second clamping grooves are slidably connected to both ends of the first clamping block, and the second clamping blocks are engaged with the first clamping block.
[0009] As a further improvement of the present application, sliding grooves are symmetrically formed at both ends of the first clamping block, and the second clamping block is slidably connected to the sliding grooves through tension springs.
[0010] As a further improvement of the present application, sliding openings are symmetrically formed in the first clamping block at one end of the spring, and the sliding openings communicate with the sliding grooves.

Subsequently, after placing the building materials in the top sub-sieve and covering the lid on the top, the position of all sub-sieves can be adjusted by moving the limiting plate, and then the base is started to vibrate and screen. During the screening process, due to the vibration, the spring will be driven to shake up and down, so that the elastic ball will collide violently with the lower part of the sub-sieve through the elasticity of the spring, and the materials on the sub-sieve will be hit up, effectively achieving the effect of automatically dredging the sub-sieve in the standard inspection sieve during the screening process and avoiding blockage.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will describe two implementation manners of the present application in detail with reference to the accompanying drawings.
[0021] The first implementation manner:
[0022] Figure 1 、 3 Figure -4 shows a standard test sieve for construction project quality inspection, including a base 1. A bottom plate 2 is fixedly connected to the top end of the base 1. Support rods 3 are symmetrically and fixedly connected to the top end of the bottom plate 2. A limiting plate 4 with a positioning bolt 5 is slidably connected to the support rods 3. A material collection box 6 is detachably connected to the top end of the bottom plate 2. A plurality of sub - sieves 7 are detachably connected to the material collection box 6, and the sub - sieves 7 and the material collection box 6 are engaged through a groove 9. A lid 8 is detachably connected to the top end of the sub - sieve 7, and the limiting plate 4 abuts against the lid 8. A first card slot 10 is formed in the inner wall of the sub - sieve 7. A first card block 12 is detachably connected to the first card slot 10. One end of the first card block 12 away from the first card slot 10 is fixedly connected to a spring 17. One end of the spring 17 away from the first card block 12 is fixedly connected to an elastic ball 18, and the elastic ball 18 collides with the upper and lower ends of the sub - sieve 7.
[0023] This solution can achieve that when using the standard test sieve to screen building materials, after placing the material collection box 6 on the bottom plate 2, the bottom of the sub - sieve 7 and the material collection box 6 are engaged through the groove 9. Then, the first card block 12 with the elastic ball 18 is engaged and fixed in the first card slot 10, so that they are stacked in sequence. Subsequently, after placing the building materials in the top - layer sub - sieve 7, the lid 8 is covered on the top. Then, the limiting plate 4 is moved and adjusted to position all the sub - sieves 7. Subsequently, the base 1 is started to shake and screen. During the screening process, due to the shaking, the spring 17 will be driven to shake up and down. Thus, through the elasticity of the spring 17, the elastic ball 18 will collide violently with the upper and lower segments of the sub - sieve 7, hitting up the materials on the sub - sieve 7, effectively achieving the effect of automatically dredging the sub - sieve 7 in the standard test sieve during the screening process and avoiding blockage.
[0024] The second implementation manner:
[0025] Figures 2 - 4It is shown that the inner wall of the first card slot 10 is symmetrically chiseled with a second card slot 11, and the first card block 12 is slidably connected with a second card block 14 corresponding to the second card slot 11 at both ends, and the second card block 14 is engaged with the first card block 12, and the first card block 12 is symmetrically chiseled with a slide groove 13 at both ends, and the second card block 14 is slidably connected to the slide groove 13 through a tension spring, and the first card block 12 at one end of the spring 17 is symmetrically chiseled with a slide opening 15, and the slide opening 15 is connected to the slide groove 13, and a slider 16 is slidably connected in the slide opening 15, and the slider 16 is fixedly connected to the second card block 14, and the second card block 14 can be driven to retract and retract by relative squeezing the two sliders 16, so as to facilitate the disassembly and assembly of the first card block 12, and a positioning groove 19 is chiseled at the top of the bottom plate 2, and the material receiving box 6 is engaged with the positioning groove 19, and the positioning groove 19 is provided to prevent the material receiving box 6 from driving the sub-screen to deviate and misalign during the shaking process.
[0026] This solution can be achieved. When a standard inspection sieve is used to screen the building materials, the material receiving box 6 can be placed in the positioning groove 19 on the bottom plate 2 and locked in position, and then the sub-sieve 7 can be placed on the material receiving box 6. At this time, the two sliders 16 can be held by hand and pressed and slid together, so that the slider 16 drives the second block 14 to retract into the slide groove 13. At this time, the first block 12 is inserted into the first slot 10 and the slider 16 is released, so that the second block 14 is pushed out and engaged with the second slot 11 by the tension spring in the slide groove 13, thereby fixing the first block 12, and the sub-sieves 7 are stacked in sequence. After the building materials are placed on the top layer of the sub-sieve 7, the inspection sieve is turned on for shaking screening. During the shaking process, the spring 17 drives the elastic ball 18 to collide up and down, and the material on the sub-sieve 7 is hit to avoid clogging.
[0027] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
