Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and in particular relates to a filling sand screening device. Background Art

[0002] The filler sand screening device is a device specially used for screening filler sand. It is mainly composed of a screen with a specific screen hole size for separating filler sand of different particle sizes. During operation, the user shovels the filler onto the surface of the sand screen, and screens the filler shovel while it slides on the screen surface. Larger particles cannot pass through the screen holes and remain above the screen, while smaller particles fall through the screen holes and fall below. The screened filler sand can be further processed or used as needed. During the screening process, the existing screening device may clog the screen holes due to differences in the size and shape of the filler sand particles, resulting in a decrease in screening efficiency. The angle of the screen is fixed, and when the staff shovels too much filler sand onto the screen surface, the filler sand will slide along the screen surface under the action of gravity. Due to the excessive amount of filler sand, in the process of the filler sand sliding, some filler sand that has not been completely screened slides to the outside, reducing the screening efficiency of the device.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] like Figure 1 As shown;

[0030] A filler sand screening device comprises a filter screen 1.

[0031] In this embodiment: the filler sand screening device is a device specially used for screening filler sand, which is mainly composed of a screen, and the screen has a specific screen hole size, which is used to separate filler sand of different particle sizes. During operation, the user shovels the filler onto the surface of the sand screen, and the filler shovel is screened in the process of sliding on the screen surface. Larger particles cannot pass through the screen holes and remain above the screen, while smaller particles fall below through the screen holes. The screened filler sand can be further processed or used as needed. During the screening process of the existing screening device, the angle of the screen is fixed. When the staff shovels too much filler sand onto the surface of the screen, the filler sand will slide along the surface of the screen under the action of gravity. Due to the excessive amount of filler sand, in the process of the filler sand sliding, the filler sand that is not completely screened slides to the outside, reducing the screening efficiency of the device. In order to solve this technical problem, a support component 2 and a feeding component 3 are added on this basis.

[0032] More specifically:

[0033] like Figures 1 to 7 As shown:

[0034] In combination with the above content: the support assembly 2 includes a connecting sleeve 21, a rotating rod 22 and a rotating wheel 23. The rotating rod 22 is fixedly connected to the inner side of one end of the filter screen 1. The inner side of one end of the connecting sleeve 21 is rotatably connected to the rotating rod 22. The inner sides of both ends of the rotating rod 22 are fixedly connected to the rotating wheels 23. The outer sides of the ends of the plug-in rod 26 are fixedly connected to the support plate 25. The outer sides of both ends of the first spring 27 are respectively fixedly connected to the lower surface of the support plate 25 and the inner side of the other end of the connecting sleeve 21. The outer side of the end of the connecting sleeve 21 is fixedly connected to the support leg 4. The feeding assembly 3 is installed inside the support leg 4. The outer surface of the rotating wheel 23 is provided with a groove 24.

[0035] In this embodiment: in this device, when the user is screening the filler sand, the user can pour a large amount of filler sand on the surface of the filter screen 1. At this time, under the action of the gravity of the filler sand, the end of the filter screen 1 will be driven to rotate. While the filter screen 1 rotates, it will drive the rotating rod 22 to rotate inside the end of the connecting sleeve 21, and at the same time squeeze the support plate 25. The support plate 25 and the plug rod 26 slide inside the connecting sleeve 21, and at the same time compress the plug rod 26 to store the elastic potential energy of the plug rod 26. Due to the change in the angle of the filter screen 1, the speed at which the filler sand on the surface of the filter screen 1 slides down along the filter screen 1 is reduced, so that the filter screen 1 has more sufficient time to fully filter. While the filler sand slides along the surface of the filter screen 1, The amount of filler sand decreases until all the filler sand is fully screened. At this time, the elasticity stored in the plug-in rod 26 is fully released, and the filter screen 1 returns to its initial state. The rotating design of the filter screen 1 can effectively prevent the filler sand from being blocked during the screening process. During the screening process, due to the differences in the size and shape of the filler sand particles, the screen holes may be blocked, resulting in a decrease in screening efficiency. When the screen plate rotates, the accumulated filler sand will be affected by centrifugal force, which helps to solve the blockage problem and improve the screening efficiency. While the filler sand slides, the filler sand is continuously screened to prevent the incompletely filtered filler sand from sliding along the outer side of one end of the filter screen 1 to the outside, thereby increasing the practicality of the device.

[0036] Going further:

[0037] In an optional embodiment, a rotating rope 31 is sleeved on the inside of the groove 24 opened by the rotating wheel 23 and the outer side of the end of the rotating wheel 37, and a plurality of connecting heads 32 are evenly and fixedly connected to the inner side of the rotating rope 31, and a connecting rod 33 is rotatably connected to the outer side of the end of the connecting head 32, and a connecting groove 34 is opened in the middle of the connecting rod 33, and the outer side of the end of the baffle 35 is slidably connected to the connecting groove 34 opened by the connecting rod 33, and an elliptical block 36 is fixedly connected to the outer side of the end of the baffle 35, and an elastic component 5 is arranged on the outer side of the end of the supporting leg 4, and a pressure sensor 52 is fixedly connected to one side of the supporting leg 4, and an insert rod 53 is slidably connected to the inner side of the end of the pressure sensor 52, and the outer sides of both ends of the second spring 54 are respectively fixedly connected to the outer side of the end of the pressure sensor 52 and the lower surface of the end of the U-shaped rod 51, and the U-shaped rod 51 is a U-shaped structure, and a rectangular through groove is opened on the inner side of the end of the U-shaped rod 51, and an air pump 6 is installed on the upper surface of the supporting leg 4, and the air pump 6 is connected to a connecting barrel 8, and the connecting barrel 8 is connected to the pressure rod 7.

[0038] In this embodiment, when the rotating rod 22 rotates, the rotating rope 31 inside the groove 24 will move to a certain extent. When the rotating rope 31 moves, it will drive the connecting rod 33 to rotate at a certain angle through the connecting head 32. The end of the baffle 35 is fixedly connected with an elliptical block 36. The elliptical block 36 is an elliptical structure. When the connecting rod 33 rotates, the baffle 35 will be driven to rotate through the elliptical block 36. At this time, the screened filler sand will accumulate on the surface of the baffle 35, and at the same time, pressure will be applied to the baffle 35, thereby driving the plug-in rod 26 to slide inside the connecting groove 34. A rod-shaped structure is provided on the outer side of the end of the baffle 35. The rod-shaped structure of the baffle 35 is provided inside the rectangular through groove opened by the U-shaped rod 51, thereby passing through the baffle 35. The rod-shaped structure on the outer side of the end drives the U-shaped rod 51 to move downward. When the U-shaped rod 51 moves downward, it will compress the second spring 54. At the same time, the amount of filler sand can be monitored in real time through the pressure sensor 52 and the insertion rod 53. When the filler sand reaches a certain amount, the air pump 6 can inflate the pressure rod 7 through the connecting barrel 8, thereby increasing the support for the filter screen 1, driving the filter screen 1 to rotate, accelerating the recovery speed of the filter screen 1, and increasing the efficiency of the device. When the filter screen 1 rotates, it will drive the baffle 35 to rotate, and then the baffle 35 can be rotated close to the vertical direction, so that the filler sand on the surface of the baffle 35 flows downward, preventing the filler sand from accumulating on the surface of the baffle 35, and further increasing the working efficiency of the device.

[0039] Going further:

[0040] In an optional embodiment, a curved plate 9 is fixedly connected to the upper surface of the air pump 6 .

[0041] In this embodiment: the upper surface of the air pump 6 is fixedly connected with an arc plate 9, and the arc plate 9 is an arc structure. When the staff throws the filler sand onto the surface of the filter screen 1, part of the filler sand will float to the rear of the device, which is inconvenient for subsequent staff to collect the filler sand. Through the arc plate 9, the filler sand splashed to the rear of the device can slide down along the surface of the arc plate 9, and finally accumulate inside the device, which is convenient for subsequent staff to clean and collect.

[0042] Working principle: In this device, when the user is screening the filler sand, the user can pour a large amount of filler sand on the surface of the filter screen 1. At this time, under the action of the gravity of the filler sand, the end of the filter screen 1 will be driven to rotate. While the filter screen 1 rotates, it will drive the rotating rod 22 to rotate inside the end of the connecting sleeve 21, and at the same time squeeze the support plate 25. The support plate 25 and the plug rod 26 slide inside the connecting sleeve 21, and compress the plug rod 26 to store the elastic potential energy of the plug rod 26. Due to the change in the angle of the filter screen 1, the speed at which the filler sand on the surface of the filter screen 1 slides down the filter screen 1 is reduced, so that the filter screen 1 has more sufficient time to fully filter. While the filler sand slides along the surface of the filter screen 1, the amount of filler sand is reduced until all the filler sand is gone. After the filter screen 1 is fully screened, the elasticity stored in the plug-in rod 26 is completely released, and the filter screen 1 returns to its initial state. The rotating design of the filter screen 1 can effectively prevent the clogging of the filler sand during the screening process. During the screening process, due to the differences in the size and shape of the filler sand particles, the screen holes may be clogged, resulting in a decrease in screening efficiency. When the screen plate rotates, the accumulated filler sand will be affected by the centrifugal force, which will help solve the clogging problem and improve the screening efficiency. While the filler sand slides, the filler sand is continuously screened to prevent the filler sand that is not completely filtered from sliding along the outer side of one end of the filter screen 1 to the outside, thereby increasing the practicality of the device. While the rotating rod 22 rotates, the rotating rope 31 inside the groove 24 will be moved to a certain extent. When the rotating rope 31 moves, the connecting rod 33 is driven to rotate at a certain angle through the connecting head 32. The end of the baffle 35 is fixedly connected with an elliptical block 36. The elliptical block 36 is an elliptical structure. When the connecting rod 33 rotates, the baffle 35 is driven to rotate through the elliptical block 36. At this time, the screened filler sand will accumulate on the surface of the baffle 35, and at the same time, pressure will be applied to the baffle 35, thereby driving the plug-in rod 26 to slide inside the connecting groove 34. A rod-shaped structure is provided on the outer side of the end of the baffle 35. The rod-shaped structure of the baffle 35 is provided inside the rectangular through groove opened by the U-shaped rod 51, and then the U-shaped rod 51 is driven to move downward through the rod-shaped structure on the outer side of the end of the baffle 35. When the U-shaped rod 51 moves downward, it will compress the second spring 54, and at the same time, through the pressure sensor The device 52 and the plug rod 53 can monitor the amount of the filling sand in real time. When the filling sand reaches a certain amount, the air pump 6 can inflate the pressure rod 7 through the connecting barrel 8, thereby increasing the support for the filter screen 1, driving the filter screen 1 to rotate, accelerating the recovery speed of the filter screen 1, and increasing the efficiency of the device. When the filter screen 1 rotates, the baffle 35 will be driven to rotate, and the baffle 35 can be rotated close to the vertical direction, so that the filling sand on the surface of the baffle 35 flows downward, preventing the filling sand from accumulating on the surface of the baffle 35, and further increasing the working efficiency of the device. The upper surface of the air pump 6 is fixedly connected with an arc plate 9, and the arc plate 9 is an arc structure. When the staff throws the filling sand on the surface of the filter screen 1, part of the filling sand will fall to the rear of the device.It is inconvenient for subsequent staff to collect the filling sand. Through the curved plate 9, the filling sand splashed to the rear of the device can slide down along the surface of the curved plate 9 and finally accumulate inside the device, which is convenient for subsequent staff to clean and collect.
