[0029] See attached Figure 1-4 As shown, an embodiment of the utility model provides a sand and gravel production and crushing device, including a sand and gravel crusher 100, wherein a guide shell 202 is fixedly connected to the feed place of the sand and gravel crusher 100, the top of the guide shell 202 is connected to a feed hopper 203, a through opening 308 is opened on the surface of the feed hopper 203, and the inner cavity of the through opening 308 is slidably connected to a baffle 300 for closing the feed opening of the feed hopper 203, and connecting plates 305 are fixedly installed on both sides of the baffle 300.

[0030] Sliding grooves 306 are opened on both sides of the feed hopper 203, and the surface of the connecting plate 305 is slidably connected to the inner cavity of the sliding groove 306. One end of the connecting plate 305 passes through the sliding groove 306 and extends to the outside of the feed hopper 203. Connecting blocks 303 are fixedly installed on both sides of the feed hopper 203, and the surface of the connecting block 303 is fixedly connected to the tension spring 304, and the other end of the tension spring 304 is fixedly connected to the surface of the connecting plate 305.

[0031] A fixing assembly for fixing the baffle 300 is fixedly installed on one side of the feed hopper 203 , and a support leg 101 is fixedly installed on the bottom of the crusher 100 .

[0032] Furthermore, the fixing assembly includes a fixing plate 310 fixedly installed on the top of the baffle 300, a fixing block 401 is fixedly installed on the top of one side of the feed hopper 203, a fixing ring 403 is fixedly connected to the surface of one side of the fixing block 401, a connecting rod 402 is fixedly connected at the center of one side of the fixing plate 310, one end of the connecting rod 402 passes through the fixing block 401 and the fixing ring 403 in sequence and extends to the outside of the fixing ring 403, a hand-tightening bolt 400 is threadedly connected to the top surface of the fixing ring 403, one end of the hand-tightening bolt 400 passes through the inner cavity of the fixing ring 403 and abuts the surface of the connecting rod 402, by the setting of the hand-tightening bolt 400, the hand-tightening bolt 400 is tightened so that one end of the hand-tightening bolt 400 abuts the surface of the connecting rod 402, thereby facilitating the fixing of the baffle 300.

[0033] The guide housing 202 has mounting plates 200 fixedly mounted on its upper and lower sides. The mounting plates 200 are fixedly mounted to the surface of the crusher 100 by first bolts 201. The guide housing 202 can be removed by removing the first bolts 201, so that the staff can inspect the interior of the crusher 100.

[0034] Support plates 309 are fixedly installed on the inner walls on both sides of the feed hopper 203.

While pulling the baffle 300 to one side, the connecting rod 402 is driven to move to one side. When the opening area of ​​the feed port of the feed hopper 203 reaches the required area, the hand bolt 400 is tightened so that one end of the hand bolt 400 abuts against the surface of the connecting rod 402, thereby fixing the baffle 300. Subsequently, sand and gravel are filled into the feed hopper 203, and the sand and gravel flow into the crusher 100 through the guide shell 202. When crushing is completed, it flows to the outside from the discharge hopper 102 on one side.

[0038] When the equipment is finished, loosen the hand-tightening bolt 400 to release the restriction on the connecting rod 402, so that the connecting plate 305 moves to one side driven by the elastic potential energy of the tension spring 304, thereby closing the feed port of the feed hopper 203 to prevent foreign matter from falling into the equipment.
