The fixing mechanism 4 is arranged on the vibration table 1 and is used to press the sieve cover 3.

[0021] like Figure 1 , Figure 2 As shown, the fixing mechanism 4 includes a gantry 41 and a fixing rod 42. The gantry 41 is arranged on the vibration table 1 and spans across the multi-layer sieve tray 2. The fixing rod 42 is vertically threadedly connected to the gantry 41, and the lower end is rotatably connected to the sieve cover 3.

[0022] like Figure 3 , Figure 4 As shown, the sieve plate 2 includes a frame 21 and a sieve 22. The sieve 22 is horizontally arranged in the middle of the frame 21, and the aperture is arranged to decrease from top to bottom. At the same time, the bottom sieve 22 is closed to achieve layered collection of multi-level aggregates.

[0023] like Figure 3 , Figure 4 As shown, a discharge port 23 is provided in the middle of the screen 22 , and a collecting bucket 24 aligned with the discharge port 23 is provided on the lower end surface, a collecting pipe 25 is bent at the lower end of the collecting bucket 24 , and the collecting pipe 25 passes through the frame 21 horizontally.

[0024] like Figure 3 , Figure 4 As shown, a switch mechanism 5 for controlling the opening and closing of the collecting hopper 24 is provided on the frame 21, and the switch mechanism 5 includes a switch plate 51, a screw rod 52 and a hand wheel 53. The switch plate 51 passes through the collecting hopper 24 and is used to cover the discharge port 23. The screw rod 52 is horizontally threadedly connected to the frame 21 and is rotatably connected to the switch plate 51. The hand wheel 53 is provided at the outer end of the screw rod 52.

[0025] like Figure 1 , Figure 5 As shown, a support frame 6 is arranged beside the vibration table 1, and the support frame 6 includes a frame body 61, a rotating shaft 62 and a multi-layer bracket 63. The frame body 61 is arranged vertically, the rotating shaft 62 is vertically rotatably connected to the frame body 61, and the multi-layer brackets 63 are distributed on the rotating shaft 62 at intervals.

[0026] like Figure 5 As shown, multiple layers of collecting trays 64 are provided on the bracket 63, and each layer of collecting trays 64 is provided with multiple collecting trays 64. The multiple collecting trays 64 are evenly distributed around the bracket 63. After rotation, the collecting trays 64 are located below each collecting tube 25 to realize the collection of aggregates after screening.

[0027] like Figure 5As shown, a plurality of C-shaped protective covers 65 are arranged on the frame 61 , and the collecting plates 64 of each layer are rotated and embedded in the protective covers 65 , and a row of collecting plates 64 of each layer are also located at the opening position of the protective covers 65 .

[0028] When the aggregate needs to be screened, the multiple layers of sieve plates 2 are stacked and placed on the vibration table 1, and the apertures of the sieve plates 2 are stacked gradually and arranged in a decreasing manner from top to bottom. Then the fixing rod 42 is controlled to rotate, and the sieve cover 3 is driven to move downward by the fixing rod 42, and gradually buckled on the uppermost sieve plate 2, and then the aggregate is put into the uppermost sieve plate 2 along the feed opening 31 on the sieve cover 3.

[0029] Then, the hand wheel 53 is controlled to rotate the screw 52, ​​and the screw 52 is used to drive the switch plate 51 to slide horizontally, and the discharge port 23 on the screen 22 is covered and blocked. Then, the vibration table 1 is started to realize the vibration control of all the screen plates 2, and the automatic screening of the aggregate is realized.

[0030] After the screening is completed, the vibration table 1 is stopped, and then the hand wheel 53 is controlled to drive the screw 52 to rotate in the opposite direction, and the screw 52 is used to drive the switch plate 51 to slide in the opposite direction, and the discharge port 23 on the screen 22 is opened. At this time, the aggregate on the screen 22 can slide outward along the collection bucket 24 and the collection pipe 25, and the aggregate is automatically discharged.

[0031] And during the aggregate discharge process, the support frame 6 is pushed to the side of the vibration table 1, and the rotating shaft 62 is controlled to rotate, so that the rotating shaft 62 drives the bracket 63 to rotate, and one row of collection trays 64 is located at the opening position of the protective cover 65, and at the same time located under each collection pipe 25, so that the screened aggregate can be collected into the collection tray 64 along the collection pipe 25 to achieve directional collection.

[0032] After collecting once, the rotation can be controlled so that the next row of collecting trays 64 are located outside the protective cover 65 to collect the next batch of aggregates. At the same time, the remaining collecting trays 64 are located inside the protective cover 65 to protect the aggregates and prevent external factors from affecting the quality of the aggregates, which is conducive to accurate measurement in the later stage.

[0033] Therefore, by providing a collecting hopper 24 and a collecting pipe 25 that can automatically guide the aggregate on each layer of the sieve plate 2, the aggregate on each layer of the sieve plate 2 can be guided and transported after screening, thereby realizing automatic cleaning and collection of the aggregate on the sieve plate 2, and realizing continuous screening of multiple batches of aggregates, thereby improving test efficiency.

[0034] At the same time, a collecting tray 64 capable of classifying and storing the screened aggregates is arranged beside the vibration table 1, so that the screened aggregates can be collected regularly and stored stably, which is convenient for later detection.

[0035] like Figure 3 , Figure 4 As shown, a groove 26 is provided on the inner side of the frame 21, and a pushing mechanism 7 is provided in the groove 26. The pushing mechanism 7 is used to push the aggregate on the screen 22 to the discharge port 23. The pushing mechanism 7 includes a pushing plate 71, a driving ring 72, a handle 73, a locking piece 74, a guide strip 75 and a guide rod 76.

[0036] like Figure 3 , Figure 4 As shown, the push plate 71 is arranged in a triangular shape, and the tips are close to each other and contact each other to form a circle. The driving ring 72 is rotatably arranged in the groove 26 and presses the push plate 71. The handle 73 is arranged on the outer wall of the driving ring 72, and the frame 21 is provided with a strip hole 27 for the handle 73 to slide.

[0037] like Figure 3 , Figure 4 As shown, the locking member 74 is used to fix the handle 73, and the locking member 74 includes a locking hook 741 and a locking ring 742. The locking hook 741 is rotatably connected to the handle 73, and the locking ring 742 is arranged at both ends of the strip hole 27 and is used for the locking hook 741 to hook tightly.

[0038] like Figure 3 , Figure 4 As shown, the guide strip 75 is transversely arranged on the lower end surface of the push plate 71, and the bottom wall of the groove 26 is provided with a guide groove 77 arranged along the tangential direction of the frame 21 and for the guide strip 75 to slide. The guide rod 76 is vertically arranged on the push plate 71, and the driving disk is provided with an arc-shaped guide hole 78 that diverges outward, and the guide hole 78 is provided for the guide rod 76 to slide.

[0039] When it is necessary to collect the aggregate on each layer of the sieve plate 2, first release the locking hook 741 from the locking ring 742, and then control the handle 73 to reciprocate, and then the handle 73 drives the driving ring 72 to rotate. At this time, under the cooperation of the guide rod 76 and the guide hole 78 as well as the guide bar 75 and the guide groove 77, all the push plates 71 are controlled to gather together or open each other, and the aggregate around the screen 22 is pushed to the discharge port 23, so as to realize the rapid collection of the aggregate.

[0040] Therefore, by arranging a pushing mechanism 7 on the sieve plate 2, the aggregates around the sieve plate 2 are pushed to the middle position and discharged along the collecting bucket 24 and the collecting pipe 25, thereby improving the collection efficiency of the aggregates.

[0041] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
