[0001] The utility model relates to the technical field of mine water washing machine sand processing, in particular to a sand bailer capable of reducing material wear. Background Art

[0002] At present, the existing high-quality water-washed machine-made sand mainly uses relaxation screens for stone powder grading and screening. The material under each relaxation screen is introduced into two sets of Neptune wheel sand bailers through the water system.

[0003] The existing design uses a conical bucket made of galvanized steel plate. Two diversion ports are located flush with the bottom of the bucket, and the water is introduced into the corresponding wheeled sand dredger through the diversion groove. The disadvantage of this design is that the bottom and sides of the conical bucket and the diversion groove will be worn and perforated by the mixture of machine-made sand and water in a short period of time, resulting in leakage.

[0006] Preferably, the guide groove is arranged at a twelve-degree angle with the side surface of the flat-bottomed conical bucket, and the end of the guide groove is fixedly connected with a rubber protective skin.

[0007] Preferably, the buffer material layer is formed by piling up aggregates with a particle size of about 20 cm.

[0008] Preferably, the lower surface of the protective plate is provided with a base frame, and both sides of the lower surface of the base frame are fixedly connected with convex rods, the inner part of the convex rods is rotatably connected to the hinge block 2, one side surface of the hinge block 2 is fixedly connected to the telescopic rod, the other end of the telescopic rod is fixedly connected to the hinge block 1, the inner part of the hinge block 1 is rotatably connected to the hinge head 2, and the hinge head 2 is fixedly connected to the inner wall of the flat-bottomed conical bucket.

[0009] Preferably, a spring is movably sleeved on the surface of the telescopic rod, one end of the spring abuts against one side surface of the hinge block 2, and the other end of the spring abuts against the side surface of the hinge block 1, and sliding grooves are provided on both side surfaces of the protective plate. Both ends of the base frame are fixedly connected to side blocks, and the inner wall of the side block is fixedly connected to a clamping rod, which is slidably clamped in the sliding groove.

[0010] Preferably, a protrusion is fixedly connected to the upper surface of the base frame, and the protrusion is located inside the through groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By laying a buffer layer on the inner bottom of the flat-bottomed conical bucket, when the machine-made sand and water mixture falls to the inner bottom of the flat-bottomed conical bucket, the impact of the machine-made sand and water mixture on the inner bottom of the flat-bottomed conical bucket will be blocked by the buffer layer, thereby achieving wear buffering, reducing the wear of the flat-bottomed conical bucket to a minimum, and greatly extending the service life of the device.

[0013] 2. By providing a protective plate, when the machine-made sand and water mixture falls into the inside of the flat-bottomed conical bucket, it will directly fall on the upper surface of the protective plate. At this time, the protective plate will bear the impact force of the machine-made sand and water mixture, and when the protective plate is impacted, the spring will be compressed, so that the impact force on the protective plate is effectively buffered. Subsequently, part of the machine-made sand and water mixture will fall from the inside of the through groove to the inner bottom of the flat-bottomed conical bucket, and the remaining part of the machine-made sand and water mixture will slide along the upper surface of the protective plate to the inner bottom of the flat-bottomed conical bucket, effectively providing a second layer of protection for the flat-bottomed conical bucket, further improving the service life of the machine-made sand and water diversion system device, reducing the maintenance frequency of the device, and improving safety.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1-4 A sand dredging machine for reducing material wear comprises a flat-bottomed conical bucket 1. The flat-bottomed conical bucket 1 is a flat-bottomed conical structure. The bottom end of the flat-bottomed conical bucket 1 is fixedly connected to a guide groove 2. The inner bottom of the flat-bottomed conical bucket 1 is paved with a buffer material layer 3. A guide port guide plate 4 is provided at the guide port at the bottom end of the buffer material layer 3. The inner wall of the flat-bottomed conical bucket 1 is rotatably connected to a protective plate 6 through a hinge joint 5. A plurality of through grooves 7 are provided on the surface of the protective plate 6.

[0021] Among them, the guide groove 2 is set at a twelve-degree angle with the side of the flat-bottomed conical bucket 1, and the end of the guide groove 2 is fixedly connected with a rubber protective skin 19. When discharging, a rubber protective skin 19 made of rubber material is set at the guide port of the guide groove 2 to buffer the outflow of the machine-made sand and water mixture, thereby providing wear-resistant protection for the guide groove 2 and effectively avoiding wear of the guide groove 2.

[0022] Among them, the buffer material layer 3 is composed of aggregates with a particle size of about 20 cm. When the machine-made sand and water mixture falls to the inner bottom of the flat-bottomed conical bucket 1, the impact of the machine-made sand and water mixture on the inner bottom of the flat-bottomed conical bucket 1 will be blocked by the buffer material layer 3, thereby achieving wear buffering and reducing the wear of the flat-bottomed conical bucket 1 to a minimum.

[0023] Among them, the lower surface of the protective plate 6 is provided with a base 13, and both sides of the lower surface of the base 13 are fixedly connected with a convex rod 14, and the internal rotation of the convex rod 14 is connected to the hinge block 2 12, and one side surface of the hinge block 2 12 is fixedly connected with a telescopic rod 10, and the other end of the telescopic rod 10 is fixedly connected to the hinge block 1 9. The internal rotation of the hinge block 1 9 is connected to the hinge head 2 8, and the hinge head 2 8 is fixedly connected to the inner wall of the flat-bottomed conical bucket 1, and the surface of the telescopic rod 10 is movably sleeved with a spring 11, one end of the spring 11 abuts against the side surface of the hinge block 2 12, and the other end of the spring 11 abuts against the side of the hinge block 1 9. Both side surfaces of the protective plate 6 are provided with slide grooves 17, and both ends of the base 13 are fixedly connected to the side Block 15, the inner wall of the side block 15 is fixedly connected with a clamping rod 16, and the clamping rod 16 is slidably engaged with the chute 17. When the machine-made sand and water mixture falls into the interior of the flat-bottomed conical bucket 1, it will directly fall on the upper surface of the protective plate 6. At this time, the protective plate 6 will withstand the impact force of the machine-made sand and water mixture, and when the protective plate 6 is impacted, the spring 11 will be compressed, so that the impact force on the protective plate 6 is effectively buffered, and then part of the machine-made sand and water mixture will fall from the inside of the through groove 7 to the inner bottom of the flat-bottomed conical bucket 1, and the remaining part of the machine-made sand and water mixture will slide along the upper surface of the protective plate 6 to the inner bottom of the flat-bottomed conical bucket 1, effectively providing a second layer of protection for the flat-bottomed conical bucket 1.

[0024] Among them, the upper surface of the base frame 13 is fixedly connected with a protrusion 18, which is located inside the through groove 7. When the protective plate 6 swings, the clamping rod 16 slides inside the slide groove 17. At the same time, the base frame 13 as a whole moves with the swing of the protective plate 6, thereby driving the protrusion 18 to move inside the through groove 7, effectively solving the problem of the through groove 7 being blocked during use of the protective plate 6.

[0025] Working principle: When the device is in use, when the machine-made sand and water mixture falls to the inner bottom of the flat-bottomed conical bucket 1, the impact of the machine-made sand and water mixture on the inner bottom of the flat-bottomed conical bucket 1 will be blocked by the buffer material layer 3, thereby achieving wear buffering, reducing the wear of the flat-bottomed conical bucket 1 to a minimum, and greatly extending the service life of the device. At the same time, when discharging, a rubber protective skin 19 made of rubber material is provided at the diversion port of the guide groove 2 to buffer the outflow of the machine-made sand and water mixture, thereby providing wear-resistant protection for the guide groove 2. When the machine-made sand and water mixture falls into the interior of the flat-bottomed conical bucket 1, it will directly fall on the upper surface of the protective plate 6. At this time, the protective plate 6 will withstand the impact force of the machine-made sand and water mixture, and the protective plate 6 will be impacted. When the protective plate 6 is swung, the spring 11 will be compressed, so that the impact force on the protective plate 6 is effectively buffered, and then part of the machine-made sand and water mixture will fall from the inside of the through groove 7 to the inner bottom of the flat-bottomed conical bucket 1, and the remaining part of the machine-made sand and water mixture will slide along the upper surface of the protective plate 6 to the inner bottom of the flat-bottomed conical bucket 1, effectively providing a second layer of protection for the flat-bottomed conical bucket 1, further improving the service life of the machine-made sand and water diversion system device, reducing the maintenance frequency of the device, and improving safety. When the protective plate 6 swings, the clamping rod 16 slides inside the slide groove 17. At the same time, the base frame 13 moves as the protective plate 6 swings, thereby driving the protrusion 18 to move inside the through groove 7 to dredge the through groove 7.
