Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0028] Please refer to Figures 1-5 As shown, the present utility model is a clogging-preventing building sand and gravel separator, which includes a base 11. A support rod 12 is fixedly connected to the top of the base 11 at a certain height. A screening mechanism 1 is arranged at the top of the support rod 12. A detachable mechanism 2 is arranged on the inner wall of the screening mechanism 1. The screening mechanism 1 includes a top frame 101. A limiting rod 103 is slidably connected to the inner wall of the top frame 101. By sliding the limiting rod 103 inside the top frame 101, the first spring 104 is limited to rebound, and its rebound direction is fixed. A fixed block 105 is fixedly connected to the outer wall of the limiting rod 103. A first spring 104 is fixedly connected to the outer wall of the fixed block 105. One end of the first spring 104 away from the fixed block 105 is fixedly connected to the inner wall of the top frame 101. By pushing the first spring 104 to compress through the fixed block 105 fixed on the outer wall of the screening frame 115, the screening frame 115 can be rebound conveniently later. A fixed frame 102 is fixedly connected to the top of the base 11. A pulley 106 is slidably connected to the inner wall of the top frame 101. A screening frame 115 is rotatably connected to the outer wall of the pulley 106. By rotating the four pulleys 106 fixed on the outer wall of the screening frame 115 inside the top frame 101, the screening frame 115 can be conveniently driven to move inside the top frame 101. A motor 107 is fixedly connected to the top of the fixed frame 102. The output end at the bottom of the motor 107 is fixedly connected to a transmission shaft 108 through a coupling. By starting the motor 107, the transmission shaft 108 at the output end at its bottom is driven to rotate.
[0029] A bevel gear one 110 is fixedly connected to the outer wall of the transmission shaft 108. The rotation of the transmission shaft 108 drives the rotation of the bevel gear one 110 fixed at its end. A rotating frame 109 is fixedly connected to the top of the fixing frame 102. A Y-shaped fixing frame 114 is fixedly connected to the top of the top frame 101. A fixing rod 113 is rotatably connected to the inner wall of the Y-shaped fixing frame 114. An eccentric wheel 112 is fixedly connected to the outer surface of the fixing rod 113. The rotation of the eccentric wheel 112 will push the screening frame 115 in contact with it to move, thereby jolting and screening the sand and gravel on it. A bevel gear two 111 is fixedly connected to the bottom of the fixing rod 113. A screening mesh 116 is slidably connected to the inner wall of the screening frame 115. The bottom of the top frame 101 is fixedly connected to the top of the support rod 12. The outer surface of the bevel gear two 111 is meshed with the outer surface of the bevel gear two 111. Through the meshing of the bevel gear one 110 and the bevel gear two 111, when the bevel gear one 110 rotates, the bevel gear two 111 will also rotate at the same time. The outer surface of the transmission shaft 108 is rotatably connected to the inner wall of the rotating frame 109. The outer surface of the eccentric wheel 112 is in contact with the outer wall of the screening frame 115. The number of pulleys 106 is several. The outer wall of the fixed block 105 is slidably connected to the inner wall of the top frame 101.
[0030] The disassembly mechanism 2 includes a handle 201. The outer wall of the handle 201 is fixedly connected to the outer wall of the screening mesh 116. By pulling the handle 201, the screening mesh 116 is pulled out for replacement. Two fixing boxes 204 are fixedly connected to the inner wall of the screening frame 115. A rotating rod 209 is fixedly connected to the inner wall of the fixing box 204. A rotating block 210 is rotatably connected to the outer surface of the rotating rod 209. A spring three 207 is fixedly connected to the inner wall of the fixing box 204. One end of the spring three 207 away from the inner wall of the fixing box 204 abuts against a top block one 208. By the spring three 207 fixed to the inner wall of the fixing box 204 losing its restraint, the top block one 208 fixed to its other end is pushed to move. A spring two 206 is fixedly connected to the inner wall of the fixing box 204. One end of the spring two 206 away from the inner wall of the fixing box 204 is fixedly connected to a top block two 211. A pull rod 202 is slidably connected to the inner wall of the fixing box 204. A pull block 203 is fixedly connected to the outer wall of the pull rod 202. By pulling the pull block 203, the pull rod 202 fixed to it is driven to move at the same time. When the pull rod 202 moves, it will push the rotating block 210 to rotate on the rotating rod 209. An upper locking rod 205 is fixedly connected to the outer wall of the screening mesh 116. The outer surface of the upper locking rod 205 is clamped with the outer surface of the rotating block 210. The outer wall of the top block one 208 is in contact with the outer wall of the upper locking rod 205. The outer wall of the top block two 211 is in contact with the outer wall of the rotating block 210. By the rotating block 210 disengaging from the groove of the upper locking rod 205 fixed to the outer wall of the screening mesh 116, the screening mesh 116 is unfixed.
[0031] A specific application of this embodiment is:
[0032] The staff first pour the sand and gravel to be screened onto the screening mesh 116. At this time, start the motor 107 to drive the transmission shaft 108 to rotate inside the rotating frame 109. When the transmission shaft 108 rotates, it will drive the first bevel gear 110 fixed at its end to rotate. Since the first bevel gear 110 meshes with the second bevel gear 111, when the first bevel gear 110 rotates, the second bevel gear 111 will also rotate simultaneously. At this time, the fixed rod 113 fixed on the top of the second bevel gear 111 will also rotate simultaneously. At the same time, the eccentric wheel 112 fixed on the outer surface of the fixed rod 113 will also rotate. When the eccentric wheel 112 rotates, it will push the screening frame 115 in contact with it to move. At this time, the four pulleys 106 fixed on the outer wall of the screening frame 115 will rotate inside the top frame 101, thereby driving the screening frame 115 to move. At the same time, the fixed block 105 fixed on the outer wall of the screening frame 115 will push the first spring 104 to compress, and the limiting rod 103 will also slide inside the top frame 101 to limit the rebound of the first spring 104 and fix its rebound direction. When the eccentric wheel 112 rotates to the other half circle, the thrust of the eccentric wheel 112 on the screening frame 115 will become smaller. At this time, the first spring 104 will lose pressure and push the fixed block 105 to move, and at the same time, the screening frame 115 will also move. The advantage is that it shakes the screening mesh 116 back and forth, which is convenient for screening the sand and gravel on it. At the same time, it can shake off the adhered sand and gravel to prevent it from being blocked. When the screening mesh 116 needs to be replaced, pull the pulling block 203 to drive the pull rod 202 fixed to it to move simultaneously. When the pull rod 202 moves, it will push the rotating block 210 to rotate on the rotating rod 209. At this time, the second top block 211 on the outer wall of the rotating block 210 will press downwards, and at the same time, the second spring 206 fixed to the second top block 211 will also compress. At this time, the rotating block 210 will disengage from the slot of the locking rod 205 fixed on the outer wall of the screening mesh 116. When the rotating block 210 disengages, the third spring 207 fixed on the inner wall of the fixed box 204 will lose its restriction and push the first top block 208 fixed at its other end to move. At this time, pull the handle 201 and pull out the screening mesh 116 for replacement. The advantage is that when the screening mesh 116 is damaged, it can be quickly replaced to prevent affecting the work efficiency.
