[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1:
[0023] See also Figure 1-Figure 4 As shown, a crushing and screening device for sand material processing comprises a crusher body 1, a feed port 2 and a discharge port 3, wherein the feed port 2 is arranged at the top of the crusher body 1, and the discharge port 3 is arranged at the bottom of the crusher body 1, and the feed port 2 and the discharge port 3 are connected with each other, and sand and gravel need to be placed at the feed port 2 of the crusher body 1, so that the sand and gravel at the feed port 2 can be crushed when the crusher body 1 is running, and the sand and gravel are discharged from the discharge port 3, and a sand material screening structure 4 is arranged at the bottom corner of the crusher body 1, and the sand material screening structure 4 comprises a collecting trough 42, and both ends of the collecting trough 42 are welded to the inner wall of the discharge port 3, and the sand material formed by the crushed sand and gravel falls into the collecting trough 42, and the inside of the collecting trough 42 A fixed shaft 43 is connected, and a driving motor 41 is provided at the end of the fixed shaft 43 and located on the side wall of the crusher body 1, and the fixed shaft 43 can be driven to rotate by the driving motor 41. A connecting rod 45 and a swing plate 44 are provided on the cylindrical surface of the fixed shaft 43 and located inside the collecting trough 42. The swing plate 44, the connecting rod 45 and the fixed shaft 43 rotate synchronously. A drop trough 46 is provided on the cylindrical surface of the collecting trough 42, and the drop trough 46 is located at the busbar at the bottom end of the collecting trough 42. The rotating fixed shaft 43 drives the connecting rod 45 and the swing plate 44 to rotate, and the swing plate 44 moves the sand so that the fine sand in the sand is screened out, and the fine sand crushed by the crusher body 1 can fall from the drop trough 46.
[0024] In this embodiment, the two ends of the fixed shaft 43 are rotatably connected to the two ends of the collecting trough 42, and there is a gap between the edge of the swing plate 44 and the inner wall of the collecting trough 42. Since there is a gap between the edge of the swing plate 44 and the inner wall of the swing plate 44, fine sand falls from the gap; the position of the drop trough 46 is aligned with the position of the discharge port 3, and the bottom end of the driving motor 41 is fixed to the crusher body 1 by bolts, so that the fixed shaft 43 can rotate the swing plate 44, and the sand can fall from the drop trough 46 and the discharge port 3.
[0025] In this embodiment, a gravel screening structure 5 is arranged on the outside of the fixed shaft 43, and the gravel screening structure 5 includes a second feeding trough 52. The second feeding trough 52 is opened on the cylindrical surface of the collecting trough 42, and the rotating swing plate 44 can move the relatively large sand and gravel, and the swing plate 44 moves the sand and gravel to be discharged from the second feeding trough 52. The groove width at both ends of the second feeding trough 52 changes from small to large. A baffle plate 53 and a row of partition plates 54 are welded to the outer wall of the collecting trough 42. The upper end of the partition plate 54 corresponds to the second feeding trough 52, so that sand and gravel can be discharged from different positions of the second feeding trough 52, and sand and gravel of different sizes can be discharged from different positions through the partition plate 54.
[0026] In this embodiment, a chamfer 51 is provided on the edge of each swing plate 44, the widest end of the second material chute 52 is at the largest distance from the edge of the swing plate 44, and the narrowest end of the second material chute 52 is at the smallest distance from the edge of the swing plate 44, smaller sand and gravel can be pushed from a smaller gap by the swing plate 44, and larger sand and gravel can be pushed from a larger gap by the swing plate 44, so that sand and gravel of different sizes can be discharged from different positions of the second material chute 52.
[0027] In this embodiment, the width of the narrowest end of the second feeding trough 52 is greater than the width of the first feeding trough 46, and the axial position of the fixed shaft 43 is located at the height of the bottom edge of the second feeding trough 52. When the swing plate 44 rotates, the sand and gravel can slide out of the collecting trough 42.
[0028] When the utility model is in use, it is necessary to crush relatively large sand and gravel into fine sand during sand processing, and put the sand and gravel into the feed port 2 of the crusher body 1, so that the sand in the feed port 2 is crushed into fine sand, and the fine sand and smaller sand and gravel fall into the collecting trough 42, and the driving motor 41 drives the fixed shaft 43 to rotate, and the fixed shaft 43 drives the swing plate 44 to rotate, so that the fine sand is discharged from the drop trough 46 and the discharge port 3, and the relatively large sand and gravel can be moved by the swing plate 44 and the fixed shaft 43, so that the fine sand is screened out from the sand and gravel. Since the sand and gravel are located in the collecting trough 42 and are not cleaned in time, the inside of the collecting trough 42 will be blocked. At this time, the sand and gravel need to be removed from the inside of the collecting trough 42, because the swing plate 44 drives the sand and gravel to be moved when it rotates. 4 is provided with a chamfer 51, the widest end of the second feeding trough 52 is at the largest distance from the edge of the swing plate 44, and the narrowest end of the second feeding trough 52 is at the smallest distance from the edge of the swing plate 44, smaller sand and gravel can be moved by the swing plate 44 from a relatively small gap, and larger sand and gravel can be moved by the swing plate 44 from a relatively large gap, and sand and gravel of different sizes are discharged from different positions of the second feeding trough 52, and larger sand and gravel cannot be discharged from the second feeding trough 52 at a relatively narrow position, and the sand and gravel falling from the second feeding trough 52 is discharged by each partition plate 54 and slides down from the baffle plate 53, and the baffle plate 53 can separate fine sand and sand and gravel of different sizes, not only can the fine sand and sand and gravel be screened out, but also the sand and gravel can be screened according to different sizes.
[0029] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
