DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0025] See also Figures 1 to 5 The embodiment of the utility model provides a wet mortar sand screening device, which includes a frame 1, a screen plate 2 and a mounting seat 5.
[0026] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The inner walls on both sides of the frame 1 are respectively provided with a slide groove 11 and a limit groove 12, and the slide groove 11 is located below the limit groove 12. An inclined material guide plate 13 is fixedly connected to the frame 1, and the material guide plate 13 is located below the screen plate 2. The four corners of the bottom of the frame 1 are fixedly connected with supporting legs.
[0027] It should be noted that: the frame 1 is the supporting body of the device, which can enable the screening structure to operate stably. The slide groove 11 and the limit groove 12 can limit the screen plate 2 and the mounting seat 5 respectively, so that they are more stable during the back and forth movement. When the sand and gravel are screened by the screen plate 2, the sand and gravel will fall on the guide plate 13. Since the guide plate 13 is inclined, the sand and gravel will slide along the guide plate 13 after falling on the guide plate 13. At this time, a container for holding sand and gravel is placed at one end of the inclined direction of the guide plate 13 to collect the screened sand and gravel.
[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 , a sieve plate 2 is slidably connected between the chute 11, and a plurality of sieve holes are provided on the sieve plate 2, sliders 21 are fixedly connected to both sides of the sieve plate 2, and the sliders 21 are both located in the chute 11 on the same side, and limit springs 22 are fixedly connected between the two ends of the slider 21 and the inner wall of the chute 11;
[0029] The two sides of the frame body 1 are fixedly connected with mounting frames 3, and the opposite side of the mounting frames 3 is rotatably connected with a turntable 31, and a rotating rod 32 is rotatably connected between the turntables 31 near the edge, and both ends of the rotating rod 32 are fixedly connected with traction ropes 33, and the other ends of the traction ropes 33 pass through the frame body 1 and the limit spring 22 on the same side, and are fixedly connected to the slider 21, and a fixed motor 34 is fixedly connected to the mounting frame 3 on one side of the frame body 1, and the output end of the fixed motor 34 is fixedly connected to the rotating shaft of the turntable 31 on the mounting frame 3 on the same side.
[0030] It should be noted that: the sieve plate 2 can drive the sand and gravel on the sieve plate 2 to move back and forth during the back and forth movement. When the moving speed of the sieve plate 2 reaches a certain value, the sieve holes on the sieve plate 2 can be used to screen the sand and gravel. During the back and forth movement of the sieve plate 2, the limit springs 22 at both ends of the slider 21 can be continuously pulled and squeezed. The elastic characteristics of the limit springs 22 can be used to increase the amplitude of the swaying of the sieve plate 2, thereby improving the screening efficiency of the sieve plate 2 for sand and gravel.
[0031] It should also be noted that: start the fixed motor 34 to drive the turntable 31 to rotate. During the rotation of the turntable 31, it can drive the rotating rod 32 to rotate. During the rotation of the rotating rod 32, it can drive the turntable 31 on the other side of the frame 1 to rotate synchronously. At this time, since the distance between the rotating rod 32 and the frame 1 changes during the rotation, the traction rope 33 can be used to pull the screen plate 2 to move along the frame 1, and cooperate with the limit spring 22 to move the screen plate 2 back and forth to screen the sand and gravel on the screen plate 2.
[0032] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A reciprocating screw 4 is rotatably connected in the limiting groove 12 on any side of the frame 1, and the reciprocating screw 4 is threadedly connected to the mounting seat 5. A rotating motor 41 is fixedly connected to the side of the frame 1 close to the reciprocating screw 4, and the output end of the rotating motor 41 is fixedly docked with one end of the reciprocating screw 4. A mounting seat 5 is slidably connected between the limiting grooves 12. A plurality of sleeves 51 are fixedly connected to the bottom of the mounting seat 5, and a slidingly connected plug rod 52 is sleeved in the sleeve 51. A fixing spring 53 is fixedly connected between the top of the plug rod 52 and the inner top wall of the sleeve 51;
[0033] The top of the frame body 1 is rotatably connected to the feed hopper 6 , and both sides of the mounting seat 5 and the feed hopper 6 are rotatably connected to fixed frames 61 , and elastic ropes 62 are fixedly connected between the fixed frames 61 .
[0034] It should be noted that: during the screening of sand and gravel, the rotating motor 41 is started to drive the reciprocating screw 4 to rotate. During the rotation of the reciprocating screw 4, the mounting seat 5 can be driven to move back and forth along the limiting groove 12. When the mounting seat 5 moves back and forth, the plug rod 52 will slide on the sieve plate 2. At this time, the inner top wall of the sleeve 51 cooperates with the sieve plate 2 to squeeze the plug rod 52 and the fixing spring 53, so that the fixing spring 53 shrinks, and the plug rod 52 shrinks in the sleeve 51. When the plug rod 5 When the mounting seat 5 moves to the sieve hole of the sieve plate 2, the fixing spring 53 rebounds due to the disappearance of the limit of the sieve plate 2, and the insertion rod 52 pops out, so that the insertion rod 52 squeezes and pushes the sand and gravel in the sieve hole of the sieve plate 2, and pushes the sand and gravel in the sieve hole out. Since the bottom end of the insertion rod 52 is provided with an inclined surface, the inner wall of the sieve hole of the sieve plate 2 will be squeezed by the inclined surface of the insertion rod 52 during the continuous movement of the mounting seat 5, so that the insertion rod 52 is transformed from being subjected to a lateral force to being subjected to a vertical force, so that the insertion rod 52 continues to retract into the sleeve 51;
[0035] It should also be noted that: during the feeding process, sand and gravel can be put into the feed hopper 6. At this time, the sand and gravel can fall onto the screen plate 2 through the feed hopper 6 for screening. When the mounting seat 5 moves back and forth, the feed hopper 6 can be driven to swing back and forth by the elastic rope 62. In the process of the feed hopper 6 swinging back and forth, the sand and gravel in the feed hopper 6 can be evenly sprinkled on the screen plate 2, thereby improving the efficiency of sand and gravel screening.
[0036] The working principle of the wet mortar sand screening device provided by the utility model is as follows:
[0037] First, the device is placed at a designated work location, then the fixed motor 34 and the rotating motor 41 are powered on, and a container for holding the screened sand and gravel is placed under the inclined side of the guide plate 13, and then the sand and gravel screening work can be carried out;
[0038] When performing sand and gravel screening, first start the fixed motor 34 and the rotating motor 41, then shovel the sand and gravel into the feed hopper 6. At this time, the rotating motor 41 cooperates with the reciprocating screw rod 4 to drive the mounting seat 5 to move back and forth. At this time, the mounting seat 5 can drive the feed hopper 6 to swing back and forth through the elastic rope 62. During the swinging process of the feed hopper 6, the sand and gravel in the feed hopper 6 can be evenly sprinkled on the screen plate 2.
[0039] When the sand and gravel enter the sieve plate 2, the fixed motor 34 drives the turntable 31 to rotate. During the rotation of the turntable 31, the turntable 31 can drive the rotating rod 32 to rotate. During the rotation of the rotating rod 32, the turntable 31 on the other side of the frame 1 can be driven to rotate synchronously. At this time, since the distance between the rotating rod 32 and the frame 1 changes during the rotation, the sieve plate 2 can be pulled along the frame 1 by the traction rope 33, and cooperated with the limit spring 22, the sieve plate 2 can be moved back and forth to screen the sand and gravel on the sieve plate 2. When the moving speed of the sieve plate 2 reaches a certain value, the sieve holes on the sieve plate 2 can be used to screen the sand and gravel.
[0040] When the sieve plate 2 is moved to the position where the sieve plate 2 is located, the fixing spring 53 is retracted to cause the sieve plate 2 to be retracted and the sieve plate 2 to be retracted.
[0041] After the sand and gravel are screened by the screen plate 2, the sand and gravel will fall on the guide plate 13. Since the guide plate 13 is inclined, the sand and gravel will slide down along the guide plate 13 after falling on the guide plate 13. At this time, the sand and gravel will enter the container under the guide plate 13, and then the sand and gravel in the container can be used for wet mortar production.
[0042] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0043] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
