Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and in particular relates to a grinder for concrete production which is easy to clean. Background Art

[0002] The replacement of old and new buildings, concrete structures, etc. will generate a large amount of waste concrete. In addition, concrete mixing plants and other facilities will also generate a large amount of waste concrete blocks. At present, the main way to deal with these waste concrete is still to landfill them as construction waste. Although this method has the advantages of simplicity and low cost, it also brings problems such as occupying land resources and polluting the soil environment. In order to make the waste concrete blocks a secondary use, it is necessary to use a grinding device to crush and screen the waste concrete blocks, so that the ground waste concrete blocks can be used as recycled aggregate and mixed with grading in a certain proportion, and then add cement and water to prepare new concrete.

[0003] In the prior art, when a grinding device grinds waste gas concrete blocks, concrete powder generated easily adheres to the surface of the grinding roller. In order to ensure the overall grinding effect of the grinding roller, the grinding roller needs to be cleaned regularly. Since the grinding roller is arranged inside the device shell, it is relatively inconvenient to clean the concrete powder accumulated on the outer surface of the grinding roller and the interior of the device.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a grinder for concrete production that is easy to clean, so as to overcome the above technical problems existing in the existing related art.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model discloses a grinder for concrete production that is easy to clean. The grinder comprises a left outer shell, a right outer shell being arranged on one side of the left outer shell, a crushing roller and a grinding roller being rotatably connected in the interior of the left outer shell and the right outer shell, a driving assembly being arranged at both ends of the crushing roller and the grinding roller, a connecting and fixing assembly being arranged on the outer surfaces of the left outer shell and the right outer shell, and a supporting and moving assembly being arranged at the bottom of the left outer shell and the right outer shell.

[0008] Further, the driving component includes connecting gears, which are arranged on the outer surfaces of the shaft heads at one ends of the crushing roller and the grinding roller respectively. The connecting gears on the two crushing rollers are meshed with each other, and the connecting gears on the two grinding rollers are meshed with each other. Sprockets are arranged on the shaft heads at the other ends of the crushing roller and the grinding roller inside the left housing. A chain is meshed on the outer surface of the sprocket. A motor is fixedly connected to one side of the right housing, and the motor is fixedly connected to the shaft head of the crushing roller.

[0009] Further, the connecting and fixing component includes connecting plates, which are fixedly connected to the front of the right housing. There are two connecting plates. A bidirectional screw is arranged between the two connecting plates. A U-shaped column is threadedly connected to the outer surface of the bidirectional screw. A fixing column is fixedly connected to the bottom of the U-shaped column. A fixing plate is fixedly connected to the outside of the left housing corresponding to the U-shaped column. A fixing hole is opened at the top of the fixing plate, and the fixing column is movably connected to the fixing hole.

[0010] Further, the connecting and fixing component further includes an anti-slip rotating tube, which is fixedly connected to the bidirectional screw. A limiting column is fixedly connected to one side of the connecting plate corresponding to the U-shaped column, and the limiting column is movably connected to the U-shaped column.

[0011] Further, the supporting and moving component includes L-shaped supporting legs, which are arranged on the front and back of the left housing and the right housing. A universal wheel is fixedly connected to the bottom of the L-shaped supporting leg. Support plates are fixedly connected to the bottoms of the left housing and the right housing respectively. A rotating roller is rotatably connected to the bottom of the support plate.

[0012] Further, a number of connecting blocks are fixedly connected to the other sides of the left housing and the right housing corresponding to the connecting gears. A screw is threadedly connected to one side of the connecting block. A limiting tooth block is rotatably connected to one end of the screw, and the limiting tooth block is meshed with the corresponding connecting gear.

[0013] Further, a sealing groove is opened inside the left housing, and a sealing plate is movably connected to the inside of the sealing groove. The sealing plate is fixedly connected to the right housing.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model can connect the left shell and the right shell together through the connecting and fixing assembly. Therefore, when cleaning the crushing roller and the grinding roller inside the shell, the connecting and fixing assembly is directly driven, so that the connecting and fixing assembly is no longer connected to the left shell and the right shell. At the same time, the left shell and the right shell can be separated with the assistance of the corresponding supporting and moving assembly. At this time, the crushing roller and the grinding roller arranged inside the left shell and the right shell can be completely exposed to the outside, so that there will be no obstruction when cleaning the crushing roller and the grinding roller, thereby making the entire cleaning process more convenient.

[0016] 2. The utility model can push the limiting tooth block by rotating the screw. At this time, the operator can rotate the corresponding crushing roller or grinding roller and make the limiting tooth block mesh with the corresponding connecting gear. Repeat the above operation and make multiple limiting tooth blocks mesh with the corresponding connecting gears. The above arrangement makes it possible for multiple groups of corresponding connecting gears to be directly meshed together when the left shell and the right shell are closed together. The arrangement of the limiting tooth block makes it unnecessary to adjust the connecting gear during the closing process of the left shell and the right shell, thereby making the operation of connecting the left shell and the right shell together more convenient.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figures 1-8 As shown, the utility model is a grinder for concrete production that is easy to clean, comprising a left shell 1, a right shell 2 being provided on one side of the left shell 1, a crushing roller 3 and a grinding roller 4 being rotatably connected inside the left shell 1 and the right shell 2, a driving assembly 5 being provided at both ends of the crushing roller 3 and the grinding roller 4, a connecting and fixing assembly 6 being provided on the outer surfaces of the left shell 1 and the right shell 2, and a supporting and moving assembly 7 being provided at the bottom of the left shell 1 and the right shell 2.

[0032] By driving the connecting and fixing assembly 6, the connecting and fixing assembly 6 no longer connects and fixes the left shell 1 and the right shell 2. At this time, the left shell 1 and the right shell 2 can be separated at the corresponding supporting and moving assemblies 7, so that the operator can start to clean the outer surfaces of the crushing roller 3 and the grinding roller 4 arranged inside the left shell 1 and the right shell 2.

[0033] The left shell 1 and the right shell 2 can be connected together through the connecting and fixing component 6. Therefore, when cleaning the crushing roller 3 and the grinding roller 4 inside the shell, the connecting and fixing component 6 is directly driven, so that the connecting and fixing component 6 is no longer connected to the left shell 1 and the right shell 2. At the same time, the left shell 1 and the right shell 2 can be separated with the assistance of the corresponding supporting and moving components 7. At this time, the crushing roller 3 and the grinding roller 4 arranged inside the left shell 1 and the right shell 2 can be completely exposed to the outside, so that there will be no obstruction when cleaning the crushing roller 3 and the grinding roller 4, thereby making the entire cleaning process more convenient.

[0034] In one embodiment, for the above-mentioned drive assembly 5, the drive assembly 5 includes a connecting gear 501, and the connecting gear 501 is provided on the outer surface of the shaft head of one end of the crushing roller 3 and the grinding roller 4. The connecting gears 501 on the two crushing rollers 3 are meshed with each other, and the connecting gears 501 on the two grinding rollers 4 are meshed with each other. The other end shaft heads of the crushing roller 3 and the grinding roller 4 inside the left shell 1 are both provided with sprockets 502, and the outer surface of the sprocket 502 is meshed with a chain 503. A motor 504 is fixedly connected to one side of the right shell 2, and the motor 504 is fixedly connected to the shaft head of the crushing roller 3.

[0035] The motor 504 drives the corresponding crushing roller 3 to rotate, and the crushing roller 3 drives the other crushing roller 3 to rotate through the corresponding two connecting gears 501, so that the two crushing rollers 3 can cooperate to crush the concrete blocks. The other rotating crushing roller 3 can drive the grinding roller 4 to rotate through the sprocket 502 and the chain 503. The rotating grinding roller 4 can drive the other grinding roller 4 to rotate through the corresponding connecting gear 501, so that the two grinding rollers 4 can cooperate to grind the concrete blocks crushed by the two crushing rollers 3. The setting of the crushing roller 3 and the grinding roller 4 can improve the effect of grinding the concrete blocks. At the same time, the setting of multiple connecting gears 501, sprockets 502 and chains 503 makes it possible for the two crushing rollers 3 and the grinding roller 4 to work normally after the left shell 1 and the right shell 2 are closed together, only the corresponding connecting gears 501 need to be meshed with each other.

[0036] In one embodiment, for the above-mentioned connection and fixing component 6, the connection and fixing component 6 includes a connecting plate 601, the connecting plate 601 is fixedly connected to the front surface of the right housing 2, there are two connecting plates 601, a bidirectional screw 602 is arranged between the two connecting plates 601, a U-shaped column 603 is threadedly connected to the outer surface of the bidirectional screw 602, a fixing column 604 is fixedly connected to the bottom of the U-shaped column 603, a fixing plate 605 is fixedly connected to the outside of the left housing 1 corresponding to the U-shaped column 603, a fixing hole 606 is opened at the top of the fixing plate 605, and the fixing column 604 is movably connected to the fixing hole 606.

[0037] By rotating the bidirectional screw 602, the bidirectional screw 602 can be made to drive the two U-shaped columns 603 to slide in opposite directions on the outside of the right housing 2, so that the fixing column 604 on the U-shaped column 603 can move out of the corresponding fixing hole 606. At this time, the U-shaped column 603 no longer connects the two housings through the fixing column 604 and the fixing hole 606. In summary, when separating the left housing 1 and the right housing 2, directly rotate the bidirectional screw 602, and the whole operation is relatively convenient.

[0038] In one embodiment, for the above-mentioned support and moving component 7, the support and moving component 7 includes an L-shaped support leg 701, the L-shaped support leg 701 is arranged on the front and back of the left housing 1 and the right housing 2, a universal wheel 702 is fixedly connected to the bottom of the L-shaped support leg 701, support plates 703 are fixedly connected to the bottoms of the left housing 1 and the right housing 2, and a rotating roller 704 is rotatably connected to the bottom of the support plate 703.

[0039] By rotating the bidirectional screw 602 through the anti-slip rotating tube 607, the anti-slip rotating tube 607 is provided so that there is no phenomenon of slipping when rotating the bidirectional screw 602. At the same time, the U-shaped column 603 can slide outside the limiting column 608, and the limiting column 608 is provided so that the U-shaped column 603 is more stable when moving.

[0040] In one embodiment, for the above-mentioned support and moving component 7, the support and moving component 7 includes an L-shaped support leg 701, the L-shaped support leg 701 is arranged on the front and back of the left housing 1 and the right housing 2, a universal wheel 702 is fixedly connected to the bottom of the L-shaped support leg 701, support plates 703 are fixedly connected to the bottoms of the left housing 1 and the right housing 2, and a rotating roller 704 is rotatably connected to the bottom of the support plate 703.

[0041] When the left shell 1 or the right shell 2 is moved, the corresponding universal wheel 702 and the roller 704 can rotate on the ground, which makes it more convenient to move the left shell 1 or the right shell 2. When the left shell 1 and the right shell 2 are closed together, the universal wheel 702 can be locked by the self-locking device provided on the universal wheel 702, so that the stability of the device when grinding concrete can be guaranteed. At the same time, the setting of the support plate 703 and the roller 704 can ensure the stability when supporting the corresponding shell. Since the L-shaped support leg 701 is set on the outside of the shell, the operator can push the fallen material out from between the two L-shaped support legs 701 when collecting the material falling from the bottom of the shell.

[0042] In one embodiment, for the above-mentioned left outer shell 1, the left outer shell 1 and the other side of the right outer shell 2 are fixedly connected with several connecting blocks 8 corresponding to the connecting gear 501, and one side of the connecting block 8 is threadedly connected with a screw 9, and one end of the screw 9 is rotatably connected to a limiting tooth block 10, and the limiting tooth block 10 is meshed with the corresponding connecting gear 501.

[0043] After cleaning the crushing roller 3 and the grinding roller 4 inside the left shell 1 and the right shell 2, the screw 9 is rotated directly. At this time, since the limiting tooth block 10 is in contact with the shell, the limiting tooth block 10 will not rotate with it when the screw 9 rotates, so that the limiting tooth block 10 can move under the push of the screw 9. At this time, the operator can rotate the corresponding crushing roller 3 or the grinding roller 4 and make the limiting tooth block 10 mesh with the corresponding connecting gear 501. Repeat the above operation and make multiple limiting tooth blocks 10 mesh with the corresponding connecting gears 501. The above arrangement makes it possible for multiple groups of corresponding connecting gears 501 to be directly meshed together when the left shell 1 and the right shell 2 are closed together. The arrangement of the limiting tooth block 10 makes it unnecessary to adjust the connecting gear 501 during the closing process of the left shell 1 and the right shell 2, thereby making the operation of connecting the left shell 1 and the right shell 2 relatively convenient.

[0044] In one embodiment, for the left housing 1 , a sealing groove 11 is provided on the inner side of the left housing 1 , a sealing plate 12 is movably connected inside the sealing groove 11 , and the sealing plate 12 is fixedly connected to the right housing 2 .

[0045] When the left shell 1 and the right shell 2 are connected together, the sealing plate 12 can be directly moved into the sealing groove 11 under the drive of the right shell 2. The sealing groove 11 and the sealing plate 12 cooperate to ensure the sealing of the connection between the left shell 1 and the right shell 2.

[0046] Through the above technical solution, 1. The left shell 1 and the right shell 2 can be connected together by the connecting and fixing component 6. Therefore, when cleaning the crushing roller 3 and the grinding roller 4 inside the shell, the connecting and fixing component 6 is directly driven, so that the connecting and fixing component 6 is no longer connected to the left shell 1 and the right shell 2. At the same time, the left shell 1 and the right shell 2 can be separated with the assistance of the corresponding supporting and moving components 7. At this time, the crushing roller 3 and the grinding roller 4 arranged inside the left shell 1 and the right shell 2 can be completely exposed to the outside, so that there will be no obstruction when cleaning the crushing roller 3 and the grinding roller 4, thereby making the entire cleaning process more convenient; 2. By rotating the screw 9 , the screw 9 can push the limiting tooth block 10. At this time, the operator can rotate the corresponding crushing roller 3 or grinding roller 4 and make the limiting tooth block 10 mesh with the corresponding connecting gear 501. Repeat the above operation and make multiple limiting tooth blocks 10 mesh with the corresponding connecting gears 501. The above arrangement makes it possible for multiple groups of corresponding connecting gears 501 to be directly meshed together when the left shell 1 and the right shell 2 are closed together. The arrangement of the limiting tooth block 10 makes it unnecessary to adjust the connecting gear 501 during the closing process of the left shell 1 and the right shell 2, thereby making the operation of connecting the left shell 1 and the right shell 2 together more convenient.
