[0024] As Figure 1 and Figure 2 As shown in FIG. 1, the sand supplementing device 100 comprises a moving assembly 1, a base 2, a bin 3, a first switch assembly 4, a second switch assembly 5 and a guiding assembly 6. The base 2 is connected to the moving assembly 1, and the moving assembly 1 is configured to move the base 2. The bin 3 is connected to the base 2 and can contain sand. The base 2 can be a support frame with a height, and the bottom of the base 2 is connected to the moving assembly 1. The bin 3 can be connected to the base 2, and the bin 3 is provided with an inlet 31. The first switch assembly 4 comprises a cover plate 41 and a first driving assembly 42. The cover plate 41 can cover and close the inlet 31, and the first driving assembly 42 can drive the cover plate 41 to move along a first direction X. The bin 3 is provided with an outlet 32. The second switch assembly 5 comprises a closure 51 and a second driving assembly 52. The second driving assembly 52 can drive the closure 51 to rotate along a second direction S1 to close or open the outlet 32. The guiding assembly 6 can receive the sand falling from the outlet 32 and guide the sand to a sand supplementing position.

[0025] In the embodiment, the moving assembly 1 can be an AGV trolley which can move freely, so as to move the components connected thereto. The moving assembly 1 can also be other devices which can move arbitrarily on a horizontal plane, and no more limitation is made herein.

[0026] The inlet 31 is provided on the top surface of the bin 3, so that the sand can enter the bin 3 through the inlet 31 by gravity. The first direction X can be any direction parallel to the plane in which the top surface of the bin 3 lies, and the cover plate 41 can move along the first direction X and pass through the inlet 31. The first driving assembly 42 is a linear motion mechanism such as a lead screw slide or a cylinder slide, and the first driving assembly 42 is drivingly connected to the cover plate 41, so that the first driving assembly 42 can drive the cover plate 41 to move. The area of the cover plate 41 is greater than the projection area of the inlet 31 on the plane parallel to the top surface of the bin 3, so that the cover plate 41 can completely cover the inlet 31.

[0027] The outlet 32 is provided on the bottom of the bin 3. When the outlet 32 is not closed, the sand can fall from the outlet 32 under the action of gravity. The guiding assembly 6 can be arranged below the outlet 32 to receive the sand falling from the outlet 32 and guide the sand to fall into the sand supplementing position. The sand supplementing position is the position of the sand blasting machine during use, and the sand supplementing device 100 can supplement the sand into the sand blasting machine through the sand supplementing position, so that the sand blasting machine can continue to work.

[0028] The second driving assembly 52 can comprise a motor, and the cover 51 is drivingly connected to the motor. The cover 51 can be driven by the motor to rotate along the second direction S1 to realize the closing or unclosing of the discharge port 32.

[0029] It can be understood that the moving assembly 1 can drive the base 2 connected to the moving assembly 1 to move, and the hopper 3 and other structures connected to the base 2 can also move, so that when the hopper 3 contains sand, the sand can move with the sand supplementing device 100, so that the sand supplementing device 100 can move the sand to the position where the sand needs to be supplemented. The first switch assembly 4 is arranged to open the inlet 31 of the hopper 3 when the sand needs to be supplemented, and to close the inlet 31 when the sand does not need to be supplemented, so as to ensure the reliability of the hopper 3 in use. Similarly, the second switch assembly 5 also enables the hopper 3 to discharge only in use, and the action process is controllable, which is beneficial to sand supplementing. The guide assembly 6 can guide the sand to the sand supplementing position, so that the sand supplementing is better.

[0030] In an embodiment, the first switch assembly 4 further comprises a sliding rail 43 extending along the first direction X, and the first driving assembly 42 can drive the cover plate 41 to move along the sliding rail 43.

[0031] In this embodiment, the sliding rail 43 can be arranged along the first direction X, so that the cover plate 41 can move along the sliding rail 43 to move along the first direction X. The sliding rail 43 can be a drawer type sliding rail 43, and recesses can be formed on both sides of the sliding rail 43. The cover plate 41 can be provided with protrusions on both sides to cooperate with the recesses. The protrusions can slide in the recesses to realize the movement of the cover plate 41 along the sliding rail 43.

[0032] It can be understood that the sliding rail 43 enables the cover plate 41 to move along the first direction X under the guidance of the sliding rail 43, so as to ensure the reliable movement of the cover plate 41 and cover or open the inlet 31 during the movement along the first direction X.

[0033] In an embodiment, the first driving assembly 42 comprises a first driving member (not shown in the figure) and a first connecting member 421 drivingly connected to the first driving member. The first connecting member 421 is connected to the cover plate 41, and the first driving member drives the cover plate 41 to move along the first direction X through the first connecting member 421.

[0034] In this embodiment, the first driving member can be an electric motor, and the first connecting member 421 can be a push rod. The first connecting member 421 can move along the first direction X under the drive of the first driving member, so as to drive the cover plate 41 connected to the first connecting member 421 to move along the first direction X.

[0035] It is understandable that the first driving component and the first connecting component 421 in the first driving assembly 42 can drive the cover plate 41 to move along the first direction X. At the same time, the cover plate 41 is slidably connected to the slide rail 43 to ensure that the cover plate 41 moves along the first direction X, so that the movement of the cover plate 41 is reliable.

[0036] In one embodiment, the first switch assembly 4 further includes a first detection element 44, which can detect whether the cover plate 41 covers the feed inlet 31.

[0037] In this embodiment, the first detection element 44 can be a sensor, which can be a photoelectric sensor, as long as it can detect the position of the cover plate 41. No further restrictions are imposed here. The first detection element 44 can be connected to the top surface of the hopper 3 and can be set near the feed inlet 31. The first detection element 44 can detect the position of the cover plate 41 to determine whether the cover plate 41 is covering the feed inlet 31 at this time.

[0038] Understandably, the first detection component 44 is designed to detect the movement of the cover plate 41, thereby controlling the opening and closing of the feed inlet 31, understanding the actual situation during the use of the hopper 3, and ensuring the reliability of the sand replenishment process.

[0039] like Figures 3 to 5 As shown, in one embodiment, the second drive assembly 52 includes a second drive member (not shown) and a second connector 521. The second connector 521 is throttlely connected to the second drive member and rotatably connected to the closure member 51. Along the second direction S1, the second drive member drives the closure member 51 to rotate through the second connector 521.

[0040] In this embodiment, the second driving member can be a motor, and the second connecting member 521 can be a motor push rod. The second driving member can drive the second connecting member 521 to move, and the closing member 51 is rotatably connected to the second connecting member 521. When the second connecting member 521 moves, the closing member 51 can rotate along the second direction S1. The portion of the closing member 51 used to close the discharge port 32 can be plate-shaped. When the discharge port 32 needs to be closed, the surface of the portion of the closing member 51 used to close the discharge port 32 abuts against the plane where the discharge port 32 is located to close the discharge port 32, so that the sand will not fall. When the discharge port 32 needs to discharge, the closing member 51 rotates, and its surface no longer abuts against the area where the discharge port 32 is located, which can release the closure of the discharge port 32, and the sand can fall from the discharge port 32.

[0041] Understandably, the second driving member and the second connecting member 521 drive the closing member 51 to rotate, so that the closing member 51 can close or release the discharge port 32. The closing member 51 is small in size to save space, while it can completely block the discharge port 32 to achieve a good sealing effect.

[0042] In an embodiment, the guiding assembly 6 comprises a guiding member 61 and a third driving assembly 62, the guiding member 61 is drivingly connected to the third driving assembly 62, and the third driving assembly 62 can drive the guiding member 61 to rotate along a third direction S2.

[0043] In the embodiment, the guiding member 61 can be a chute, which can carry the sand and guide and limit the movement of the sand. The third driving assembly 62 can comprise a motor to drive the guiding member 61 to rotate so as to guide the sand. When the guiding assembly 6 is not needed to work, the end of the guiding member 61 away from the discharge port 32 can abut against the base 2. When the guiding assembly 6 is needed to work, the end of the guiding member 61 away from the discharge port 32 is moved to a position capable of abutting the sand supplementing station so as to be capable of supplementing sand.

[0044] It can be understood that the third driving assembly 62 can drive the guiding member 61 to rotate along the third direction S2 so that the guiding member 61 is stored when not needed to be used, without occupying extra space. When the guiding member 61 is needed to work, the guiding member 61 is rotated to the position capable of abutting the sand supplementing station so that the sand supplementing device 100 can supplement sand.

[0045] In an embodiment, the third driving assembly 62 comprises a third driving member (not shown in the figure) and a third connecting member 621, the third connecting member 621 is drivingly connected to the third driving member, and the third connecting member 621 is connected to the guiding member 61. Along the third direction S2, the third driving member drives the guiding member 61 to rotate through the third connecting member 621.

[0046] In the embodiment, the third driving member can be a motor, and the third connecting member 621 can be a motor push rod. The third driving member drives the third connecting member 621 to move, and the third connecting member 621 can drive the guiding member 61 to rotate along the third direction S2 when moving so as to realize the extension and retraction of the guiding member 61.

[0047] In an embodiment, the sand supplementing device 100 further comprises a sand receiving member 7, the sand receiving member 7 is detachably connected to the base 2, and the guiding member 61 can abut against the sand receiving member 7 so that the sand receiving member 7 receives the sand falling from the guiding member 61.

[0048] In the embodiment, the sand receiving member 7 can be a sand receiving box, and the top of the sand receiving box is provided with an opening so that the sand falling from the guiding member 61 can be accommodated in the sand receiving member 7. The sand receiving member 7 is detachably connected to the base 2 so as to be capable of being replaced and cleaned after the sand receiving member 7 is filled with sand, which is more convenient for actual use.

[0049] It can be understood that when the guiding member 61 completes the conveying of sand, there can be some residual sand on the guiding member 61. At this time, the guiding member 61 is moved to abut against the sand receiving member 7, and the residual sand on the guiding member 61 falls into the sand receiving member 7 so as to be collected by the sand receiving member 7, and the sand receiving member 7 can be subsequently detached for cleaning.

[0050] In an embodiment, the guide 61 comprises a fixed part 611 and a rotating part 612, the fixed part 611 is connected to the base 2, the fixed part 611 is capable of receiving the sand falling from the discharge port 32, the rotating part 612 is rotatably connected to the fixed part 611, and the third driving assembly 62 is configured to drive the rotating part 612 to rotate along the third direction S2.

[0051] In the embodiment, the fixed part 611 is fixedly connected to the base 2, and the fixed part 611 is located below the discharge port 32, so that the sand falling from the discharge port 32 first falls into the fixed part 611 and then falls into the rotating part 612 through the fixed part 611. The fixed part 611 and the rotating part 612 can be connected through a hinge, so that the rotating part 612 can rotate relative to the fixed part 611 under the driving of the third driving assembly 62.

[0052] It can be understood that the guide 61 comprises the fixed part 611 and the rotating part 612 to ensure that the guide 61 is firmly connected and can rotate according to the working condition, and also ensure that the sand falls into the designated position.

[0053] In an embodiment, the sand supplementing device 100 further comprises a second detecting member 8, which can detect the weight of the sand in the sand bin 3.

[0054] In the embodiment, the second detecting member 8 can be a weighing sensor, which can sense the weight of the sand in the sand bin 3. The second detecting member 8 can be provided with multiple, for example, three, and is connected to the base 2 and located below the sand bin 3 to obtain the weight of the sand bin 3.

[0055] It can be understood that the second detecting member 8 can detect the weight of the sand in the sand bin 3, and when the sand supplementing device 100 is in use, the amount of sand that needs to be carried in the sand supplementing device 100 can be set in advance, and the weight of the sand in the sand bin 3 is detected by the second detecting member 8 to correspond to the amount of sand set in advance to obtain the required amount of sand.
