DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 9As shown, a high-efficiency fine sand recovery device includes a screening box 1, the screening box 1 is respectively provided with a feed port 11, a discharge port 12 and a slag discharge port 15, a rotating door 16 is provided at the slag discharge port 15 of the screening box 1, a plurality of vibration plates 2 are arranged inside the screening box 1, a vibration mechanism 13 for vibrating the vibration plates 2 is arranged on the screening box 1, a movable screening plate 3 is arranged on the vibration plate 2, and one side of the screening plate 3 can pass through the screening box 1, a limiting groove 21 for the screening plate 3 to move is also arranged on the vibration plate 2, and a limiting mechanism 4 for fixing the screening plate 3 is also provided on the screening box 1.

[0027] When it is necessary to recycle fine sand, firstly, the external pipe is connected to the feed port 11 of the screening box 1, and the vibration mechanism 13 is turned on at the same time to drive the vibration plate 2 to vibrate, and then the screening plate 3 is synchronously driven to vibrate, and then the fine sand to be recovered is transported to the inside of the screening box 1 through the external pipe, so that the fine sand will fall on the screening plate 3, and then the fine sand will be filtered by the vibration of the screening plate 3. Because the screening plate 3 has multiple screening plates, the fine sand can be better filtered, and then the filtered fine sand will automatically fall to the bottom of the screening box 1, and then pass through the outlet of the screening box 1. The material port 12 leaks outward, and then the leaked fine sand is recovered, and then the impurities on the screening net are removed from the slag outlet 15 of the screening box 1 by opening the rotating door 16, and the screening plate 3 can be moved in the limiting groove 21 of the vibration plate 2, so that the screening plate 3 can be quickly removed from the screening box 1, and then the screening plate 3 can be cleaned or replaced, thereby reducing the impact on the recovery of fine sand, and the screening plate 3 can be quickly fixed on the screening box 1 through the limiting mechanism 4, further improving the convenience of fixing the screening plate 3.

[0028] Reference Figure 4 As shown, the limiting mechanism 4 includes a rotating shaft 42 and a flip plate 41; the number of the rotating shafts 42 is the same as the number of the screening plates 3, and the rotating shafts 42 are arranged on the screening box 1 through a bearing seat; the number of the flip plates 41 is the same as the number of the rotating shafts 42 and are arranged on the rotating shafts 42 in a one-to-one correspondence, and the flip plates 41 can be arranged in contact with the screening box 1.

[0029] When the screening plate 3 needs to be removed from the screening box 1, the flip plate 41 is first driven to flip. Since the flip plate 41 is limited by the rotating shaft 42, the flip plate 41 is moved in the direction away from the screening plate 3, thereby opening the opening at the screening box 1. The screening plate 3 is then slid out of the limiting groove 21 of the vibration plate 2, and the screening plate 3 can be quickly removed from the screening box 1. Then, the screening plate 3 can be cleaned or replaced. Similarly, when the screening plate 3 needs to be installed in the screening box 1, it is only necessary to directly insert the screening plate 3 into the limiting groove 21 of the vibration plate 2, and then the opening at the screening box 1 is closed by rotating the flip plate 41.

[0030] Reference Figure 6 As shown, the screening box 1 is provided with a driving assembly 43 capable of automatically driving the flip plate 41 to flip, and the driving assembly 43 includes a first base 431, a first rotating motor 432, a turbine 434 and a worm 433; the first base 431 is arranged on the top of the screening box 1; the first rotating motor 432 is arranged on the first base 431, and the output end of the first rotating motor 432 can pass through the first base 431; the number of the turbines 434 is the same as the number of the rotating shafts 42 and is arranged on the rotating shafts 42 in a one-to-one correspondence; the worm 433 is arranged between the turbine 434 and the first rotating motor 432, and one side of the worm 433 is meshed with the turbine 434, and the other side is connected to the output end of the first rotating motor 432.

[0031] By starting the first rotating motor 432 on the first base 431, when the first rotating motor 432 rotates, it will synchronously drive the worm 433 to rotate, so that when the worm 433 rotates, it will also synchronously drive the turbine 434 to rotate, and then the rotating shaft 42 will rotate synchronously through the turbine 434, and then the flip plate 41 will be directly driven to rotate, thereby reducing manual operation, and when the flip plate 41 needs to be closed, it can be directly operated through the operation of the first rotating motor 432, thereby improving the convenience of operation.

[0032] Reference Figure 2 and Figure 6As shown, a conveying mechanism 5 is provided at the bottom of the screening box 1, and the conveying mechanism 5 includes a fixed plate 54, a conveying bucket 52, a hose 51 and a second rotating motor 56; the fixed plate 54 is arranged below the screening box 1, and a second base 55 is arranged on the fixed plate 54; the conveying bucket 52 is arranged on the fixed plate 54, and a feeding end and a discharging end are arranged on the conveying bucket 52, and a spiral rotating rod 53 is arranged in the conveying bucket 52; the hose 51 is vertically arranged at the discharge port 12 of the screening box 1, and the bottom of the hose 51 is connected to the feeding end of the conveying bucket 52; the second rotating motor 56 is arranged on the second base 55, and the output end of the second rotating motor 56 passes through the conveying bucket 52 and is connected to the spiral rotating rod 53.

[0033] By starting the second rotating motor 56 on the second base 55 to work, the spiral rotating rod 53 in the conveying bucket 52 continues to rotate, so that the fine sand that has been filtered multiple times will leak out from the feed port 11 of the screening box 1, and then the fine sand will be automatically transported to the input end of the conveying bucket 52 through the hose 51, and then the spiral rotating rod 53 of the bucket rotates to automatically transport the fine sand from the input end to the output end, and then the fine sand can be transported to a desired place, thereby improving the convenience of fine sand recovery.

[0034] Reference Figure 4 and Figure 5 As shown, a buffer assembly 6 is provided at the bottom of the screening box 1, and the buffer assembly 6 includes a mounting plate 61, a limiting shaft 63 and a spring 64; the mounting plate 61 is provided on the fixing plate 54 through a plurality of support columns 62; at least one of the limiting shafts 63 is provided at the bottom of the screening box 1; the springs 64 are the same in number as the limiting shafts 63 and are sleeved on the limiting shafts 63 in a one-to-one correspondence, and one end of the spring 64 is abutted against the screening box 1, and the other end is abutted against the mounting plate 61.

[0035] When the screening box 1 is used to recover fine sand, the screening plate 3 needs to be vibrated by the vibration mechanism 13, which will also cause a vibration effect on the screening box 1. When the screening box 1 vibrates, the spring 64 will be squeezed synchronously, so that the spring 64 will be compressed and have an elastic reset force, and then the screening box 1 can be reset at any time by the spring 64, thereby reducing the impact of the screening box 1 during operation, thereby increasing the speed of fine sand recovery, and limiting the spring 64 by the limit shaft 63 can prevent the spring 64 from falling off during operation.

[0036] Reference Figure 5 and Fig. 9 As shown, a fixing assembly 7 is also provided at the bottom of the screening box 1, and the fixing assembly 7 includes a fixing block 71 and a sliding block 73; at least one of the fixing blocks 71 is arranged on the mounting plate 61, and a movable moving block 72 is arranged on the fixing block 71, and the moving block 72 is connected to the screening box 1 at a side away from the fixing block 71; the sliding block 73 is arranged on the moving block 72, and the sliding block 73 is slidably connected to the fixing block 71, and a sliding groove 74 for the sliding block 73 to move is provided on the fixing block 71.

[0037] The movable block 72 can only move on the fixed block 71, thereby providing an upper and lower limit function between the screening box 1 and the mounting plate 61, and the slider 73 can only move in the slide groove 74 of the fixed block 71, so that the movable block 72 can always only move on the fixed block 71, thereby preventing the movable block 72 from detaching from the fixed block 71 in the horizontal direction, thereby affecting the effect of the screening box 1 on the recovery of fine sand.

[0038] Reference Figure 6 As shown, a guide assembly 14 is further provided inside the screening box 1 , and the guide assembly 14 includes a guide platform 141 , and the guide platform 141 is provided at the inner bottom of the screening box 1 , a guide hole 142 is provided in the middle of the guide platform 141 , and an inclined surface 143 is also provided on the guide platform 141 .

[0039] Because the aperture of the discharge port 12 of the screening box 1 is smaller than the inner diameter of the screening box 1, when the fine sand falls to the inner bottom of the screening box 1, part of the fine sand will accumulate at the inner bottom of the screening box 1, thereby causing waste. Because water is sprayed on the fine sand when filtering and recovering the fine sand, the fine sand will automatically flow toward the guide hole 142 of the guide table 141 through the inclined surface 143 of the guide table 141 through the guide table 141. Because the guide hole 142 is the same as the aperture of the discharge port 12, the fine sand will flow into the conveying bucket 52, so there is no need to manually clean the fine sand at the bottom of the screening box 1 separately, thereby saving labor and reducing the waste of fine sand.

[0040] Reference Figure 8 As shown, the screening plate 3 is also provided with a handle 31 that can be used for holding. The handle 31 is rotatably arranged on the screening plate 3 through a positioning pin. The screening plate 3 is provided with a placement groove 32 for placing the handle 31.

[0041] Because the screening plate 3 needs to be removed from the vibration plate 2 or installed on the vibration plate 2 manually, when removing the screening plate 3, you only need to directly pull the handle 31 to quickly remove the screening plate 3, thereby saving effort, and then install the screening plate 3 on the vibration plate 2, and then through the setting of the positioning pin, the handle 31 can be stored in the placement groove 32 of the screening plate 3, thereby saving space.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
