[0002] Coarse aggregates include pebbles formed by natural weathering of rocks and crushed stone produced by artificial rolling. The technical properties of coarse aggregates include both physical and mechanical properties. According to the "Specifications for Testing Aggregates in Highway Engineering", it is necessary to test the content of needle-shaped and flaky particles in coarse aggregates. In order to save labor, testing machines have appeared on the market to replace manual labor. The machine uses a vibrator to shake the coarse aggregate between layers of screens for screening. Finally, the screened coarse aggregate is collected at the bottom screen. Since the screens of the machine are interlocked, the screens need to be removed one by one after the test. The preparation work for the test process is cumbersome. Therefore, a coarse aggregate flatness ratio testing machine was designed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The bottom end of the sieve shell 201 is provided with a sieve layer 202, and the top end of the sieve layer 202 is provided with multiple flatness sieves 203; a rotating screen bottom 3, which is disposed on the inner wall of the collection shell 2 and close to one end of the sieve shell 201. The bottom end of the collection shell 2 is provided with a vibration layer 301. The bottom end of the rotating screen bottom 3 and the end located close to the collection shell 2 is provided with a rotating shaft 302. The outer wall of the collection shell 2 is provided with an outlet groove 303; and a screen plate lock 5, which is disposed on the outer wall of the rotating screen bottom 3 and the end located close to the outlet groove 303. The screen plate lock 5 also includes a lock plate 501 and a lock core 502.

[0025] It should be noted that the outer shell is divided into two parts, the collection shell 2 and the sieve shell 201, by the sieve layer 202 and the vibrating layer 301. The middle part of the sieve layer 202 has a circular annular hole. To facilitate the coarse aggregate after the test to pass through the sieve layer 202 and reach the interior of the rotating screen bottom 3, multiple flat sieves 203 are divided into different levels. The coarse aggregate to be tested starts to be screened from the top flat sieve 203. With the help of the vibration of the vibrator 4, each level of flat sieve 203 will pass the qualified material through and leave the unqualified material inside the flat sieve 203 of that level. After multiple rounds of screening, the screened coarse aggregate finally flows to the rotating screen bottom 3. At the same time, the rotating screen bottom 3 can be rotated away from the outlet trough 303 by means of the rotating shaft 302.

[0026] Specifically, the collection shell 2 is set at the top edge of the base 1, the sieve shell 201 is set at the top of the collection shell 2, the top of the sieve shell 201 is provided with a sieve cover 101, the outer wall of the multiple flat sieves 203 is sleeved with the inner wall of the sieve shell 201, the top of the multiple flat sieves 203 is provided with a fixing plate 102, and the top of the fixing plate 102 is provided with a handle 103.

[0027] It should be noted that the collecting shell 2 and the sieve shell 201 are spliced ​​together to form a single outer shell, which is set together at the top of the base 1. The collecting shell 2 is located at the bottom of the sieve shell 201. The collecting shell 2 and the sieve shell 201 are distinguished by the sieve layer 202. The flat sieve 203 is fixed to the top of the sieve layer 202 using its special structure. Simultaneously, the flat sieve 203 is fitted into the sieve shell 201.

[0028] Specifically, the top of the sieve cover 101 is provided with a round hole 104, and the outer wall of the handle 103 is inserted and connected to the round hole 104.

[0029] It should be noted that the screen cover 101 is fitted onto the top of the screen shell 201, and multiple flat screens 203 are fitted together and are flush with the height of the screen shell 201. The top of the flat screen 203 is sealed by the fixing plate 102. The size and shape of the fixing plate 102 can fit and seal the top of the flat screen 203. The handle 103 at the top center of the fixing plate 102 can be inserted through the round hole 104 and extend outward. The handle 103 can be manually pulled up and down, which at the same time drives the fixing plate 102 to open the seal.

[0030] Specifically, a first fixing plate 503 is provided on the outer wall of the rotating screen bottom 3 at the end near the outlet groove 303. A locking plate 501 is hinged to the end of the first fixing plate 503 away from the rotating screen bottom 3. A second fixing plate 504 is provided on the outer wall of the collecting shell 2 at the end near the outlet groove 303. The end of the locking core 502 near the collecting shell 2 is rotatably connected to the end of the second fixing plate 504 away from the collecting shell 2. A locking hole 505 is provided on the end of the locking plate 501 near the locking core 502. The inner wall of the locking hole 505 is sleeved with the outer wall of the locking core 502.

[0031] It should be noted that the first fixing plate 503 is installed on the outer wall of the rotating screen bottom 3 exposed at the outlet groove 303, and the second fixing plate 504 is installed on the outer wall of the screen shell 201 at the same level as the first fixing plate 503. The locking plate 501 at the front end of the first fixing plate 503 can be rotated by hinge, and can be rotated to the position of the locking core 502. The shape and size of the locking hole 505 are the same as the shape and size of the locking core 502. The locking plate 505 is fitted onto the inner wall of the locking core 502 through the locking hole 505. At the same time, the locking core 502 is rotated, so that the shape between the locking core 502 and the locking hole 505 forms a closed loop, so that the locking plate 501 is fixed to the front end of the second fixing plate 504 by the locking core 502, and at the same time, the positions of the first fixing plate 503 and the rotating screen bottom 3 are fixed.

[0032] Specifically, the bottom end of the rotating shaft 302 is fixedly connected to the top end of the vibrating layer 301 and to one end near the outlet trough 303.

A vibrator 4 is provided at the bottom end of the vibrating layer 301. The control end of the vibrator 4 is electrically connected to a remote controller 401.

[0033] It should be noted that the rotating shaft 302 is positioned between the vibrating layer 301 and the sieve layer 202. The rotation between the vibrating layer 301 and the sieve layer 202 can be achieved by using the rotating shaft 302. The fixing rod 204 at the top of the sieve layer 202 can be used to position and fix the flat sieve 203 by connecting multiple flat sieves 203. The vibrator 4 at the bottom can be started by the remote control 401.

[0034] Working principle of this utility model:

[0035] The specific operation is as follows: Flattening screens 203 are sequentially fitted onto the top of the screening layer 202, and simultaneously covered by the screening shell 201. Coarse aggregate is placed inside the flattening screens 203. Next, the screen cover 101 is fitted onto the top of the screening shell 201. The round hole 104 at the top of the screen cover 101 passes through the handle 103, allowing manual pulling of the handle 103 through the round hole 104. Simultaneously, the handle 103 pulls the fixing plate 102 within the screen cover 101. The fixing plate 102 is then placed on top of the flattening screen 203. Finally, the locking plate 5 is... 01. Rotate the lock core 502 through the lock hole 505, then rotate the lock core 502 to form a closed loop between the lock core 502 and the lock hole 505 to fix the lock plate 501. Then, start the vibrator 4 through the remote control 401. The flatness screen 203 will vibrate due to the operation of the vibrator 4. Some coarse aggregate will pass through the flatness screen 203 and fall into the interior of the rotating screen bottom 3 during the vibration. Finally, rotate the lock core 502 back to its original position and use the rotating shaft 302 to rotate the rotating screen bottom 3 out of the outlet groove 303 to take out the coarse aggregate screened in the test.
