[0030] In the embodiment of the utility model, the sand screening drum can be supported by utilizing the arrangement of support roller one 11 and support roller two 12. At the same time, support roller one 11 is arranged on both sides below the sand screening drum to provide rolling support thereto, and support roller two 12 is three in number and evenly distributed on the outside of the fixed sleeve 141 to provide limiting support thereto, so that the sand screening drum can be stably placed on the base frame 1 and perform the rotating sand screening operation.

[0031] In the embodiment of the utility model, the driving motor 131 is configured to drive the sand screening drum to rotate through the meshing of the small bevel gear 132 and the large bevel gear 142, and then the rotation of the sand screening drum is used to make the sand roll on the screen to perform sand screening.

[0032] The annular baffle 14 is arranged on the other side above the base frame 1, and a fixed sleeve 141 is installed on its outer surface. A large bevel gear 142 is installed on the outer surface of the fixed sleeve 141, and the large bevel gear 142 is meshed with the small bevel gear 132. A concave slide rail 143 is installed on the outer end of the fixed sleeve 141, and the supporting pulley 2 12 is movably embedded in the concave slide rail 143; the fan-shaped plate 15 is evenly installed on the outer end of the annular baffle 14, and its central angle is 45°. An outer arc baffle 151 is installed on the outer end of its side surface, and an inner arc baffle 152 is installed on the inner end of its side surface. The length of the outer arc baffle 151 is greater than that of the inner arc baffle 152. The same concave slide rail 143 is installed on one end of the outer surface of the outer arc baffle 151, and the supporting roller 11 is movably embedded in this concave slide rail 143.

[0033] In the embodiment of the utility model, by using the arrangement of the fan-shaped plate 15 and by installing the outer arc baffle 151 and the inner arc baffle 152 on one side, the adjustable screen mechanism 2 can be embedded between the outer arc baffle 151 and the inner arc baffle 152 and rotate therein. At the same time, by using the fan-shaped plate 15 evenly distributed on the outer end of the annular baffle 14, the outer arc baffle 151 and the inner arc baffle 152 can form a cylinder with evenly distributed sand screening ports, so that the screen can perform sand screening through the evenly distributed sand screening ports.

[0034] In the embodiment of the utility model, by using the setting of the inner arc baffle 152, the screen between the outer arc baffle 151 and the inner arc baffle 152 can be covered, so that the device can screen through a single screen to ensure the quality of sand screening.

[0035] In the embodiment of the utility model, the concave slide rail 143 provided at the outer end of the outer arc-shaped baffle 151 can ensure the fixing strength of the outer arc-shaped baffle 151, so that it maintains a stable cylindrical shape, so as to ensure smooth rotation of the device.

[0036] The adjustable screen mechanism 2 is arranged between the outer arc baffle 151 and the inner arc baffle 152, and includes: eight strip fixing plates 21, which are slidably arranged between the outer arc baffle 151 and the inner arc baffle 152; a coarse screen 22, which is arranged between two adjacent strip fixing plates 21, is arranged in an arc shape, and is located between the outer arc baffle 151 and the inner arc baffle 152; a fine screen 23, which is arranged between two adjacent strip fixing plates 21, is staggered with the coarse screen 22, and is arranged in an arc shape between the outer arc baffle 151 and the inner arc baffle 152.

[0037] In the embodiment of the utility model, the strip fixing plate 21 is used to fix the coarse screen 22 and the fine screen 23 respectively, and the coarse screen 22 and the fine screen 23 are staggered, so that a screen cylinder with alternating screen distribution can be formed, and then the coarse screen 22 and the fine screen 23 can be exposed alternately by rotating the outer arc baffle 151 and the inner arc baffle 152, so that the device can control the number of screened sand meshes according to actual conditions, thereby improving the scope of use.

[0038] The adjusting baffle 24 is parallel to the sector plate 15 and is located at one end of the outer arc baffle 151. It is fixedly connected to the outer arc baffle 151 through a fixing rod 241.

A plurality of adjusting rods 246 are installed at the other end of the adjusting shaft 242. The adjusting rods 246 are connected to the strip fixing plate 21.

[0039] In the embodiment of the utility model, the transmission coordination and self-locking property of the adjusting worm 244 and the worm gear 243 can ensure the stability of the screen after adjustment, and avoid the problem of uneven screening due to accidental exposure.

[0040] In the embodiment of the utility model, by supporting the adjusting baffle 24 with the fixing rod 241, the screened impurities can be discharged through the gap between the fixing rods 241, and by connecting the adjusting rod 246 with the strip fixing plate 21, the adjusting shaft 242 can drive the screen to rotate through the adjusting rod 246 to adjust the screening coarseness.

[0041] The feed funnel 16 is arranged on one side of the fixed sleeve 141 and fixedly connected to the base frame 1 , and a feed inclined pipe 161 is installed at the lower end thereof. The feed inclined pipe 161 obliquely passes through the fixed sleeve 141 and the annular baffle 14 .

[0042] In the embodiment of the utility model, the feed funnel 16 and the feed inclined tube 161 are arranged to facilitate the injection of raw materials into the screen drum for screening.

[0043] In the utility model, the sector plates 15 are symmetrically distributed along the vertical center line of the annular baffle 14, so that the screened sand can be discharged through the sand screening port directly below, ensuring that the screened sand falls quickly.

[0044] In the present invention, the width of the coarse screen 22 and the fine screen 23 is the same as the width of the inner arc baffle 152, so that the inner arc baffle 152 can cover the coarse screen 22 and the fine screen 23, thereby ensuring the quality of screened sand.

[0045] In the utility model, the strip fixed plate 21, the coarse screen 22 and the fine screen 23 are spliced ​​into an annular screen cylinder, and the coarse screen 22 and the fine screen 23 are staggered; by rotating it, the coarse screen 22 and the fine screen 23 can be alternately moved to the sand screening port for screening, thereby adjusting the coarseness of the sand screening device.

[0046] When the utility model is used, the staff moves the device to the sand screening location, and then connects the device to an external power source, and then adjusts the screen according to the coarseness of the sand screened;

[0047] The staff manually rotates the adjustment handle 245, so that the worm gear 243 is driven to rotate through the adjustment worm 244, and then the worm gear 243 drives the adjustment shaft 242 to rotate, so that the adjustment shaft 242 drives the bar fixing plate 21 to rotate through the adjustment rod 246, and then the bar fixing plate 21 drives the coarse screen 22 and the fine screen 23 to rotate, so that the fine screen 23 or the coarse screen 22 is moved out from under the inner arc baffle 152 through rotation, and until the coarse screen 22 or the fine screen 23 is completely moved out of the inner arc baffle 152, so that the coarse screen 22 or the fine screen 23 is moved between two adjacent outer arc baffles 151;

[0048] Then the staff can control the driving motor 131 to work, so that it can drive the fixed sleeve 141 to rotate through the meshing of the small bevel gear 132 and the large bevel gear 142, and then the annular baffle 14 drives the fan plate 15 to rotate, so that the fan plate 15 drives the outer arc baffle 151 and the inner arc baffle 152 to rotate, and the adjustable screen mechanism 2 rotates synchronously with the annular baffle 14 by connecting the fixed rod 241;

[0049] Then, the staff can pour the sand into the feed funnel 16, and inject the sand into the screen drum composed of the coarse screen 22 and the fine screen 23 through the feed inclined tube 161. At the same time, the sand is screened through the corresponding screen by using the shielding of the inner arc baffle 152. The sand is turned over in the screen drum by the rotation of the screen, and then the sand is screened through the screen. The screened sand is discharged from between the inner arc baffle 152 and the outer arc baffle 151 to the bottom, and impurities can be discharged through the gap between the fixing rods 241.
