Description

Technical Field

[0001] The invention relates to the technical field of recycled aggregate mixers, in particular to an automatic feeding mixer. Background Art

[0002] Recycled aggregates are used to mix cement and sand in a mixer to make recycled aggregate concrete. The mixing of recycled aggregates is mainly carried out by a planetary vertical shaft mixer. Recycled aggregates, cement and sand are fed into the planetary vertical shaft mixer using a one-time feeding method. The feeding elevator placed outside the planetary vertical shaft mixer automatically transports the recycled aggregates, cement and sand upward to the top of the hopper on the top of the planetary vertical shaft mixer. The materials enter the mixer from the hopper on the top of the planetary vertical shaft mixer by automatic falling or hopper flipping. Recycled aggregates, cement and sand are piled up by operators in different areas of the feeding belt for transportation and feeding operations. It is impossible to separate and pile up materials on the feeding belt in a large range according to steps during the automatic feeding process using the one-time feeding method. It is easy for the separation layer of materials to fail to be maintained during the automatic feeding process. At the same time, in the process of transporting to the top of the elevator for unloading, the materials cannot be kept in a separated and stacked state, so that in the process of automatic feeding, the materials cannot form a stacking state of lower layer recycled aggregate, middle layer cement, and upper layer sand, and maintain this state for feeding and positioning unloading, affecting the feeding effect of feeding the recycled aggregate into the mixer by using the one-time feeding method.

The combination top frame 42 is fixedly connected to the top of the outer frame 31. The drive chain assembly block 41 is fixedly connected to the top of the combination top frame 42 through the fixed column 43. The drive chain assembly block 41 is engaged with the drive chain on the inner side of the loading and lifting frame 2. The top of the loading and lifting frame 2 is fixedly connected with a counter-position pushing module 5. The counter-position pushing module 5 comprises a fixed top plate 51, a first pushing driving member 52 and a combination bottom frame 53. The combination bottom frame 53 is fixedly connected to the output end of the first pushing driving member 52. The bottom end of the combination bottom frame 53 is engaged with the drive chain assembly block 41. The top of the feed hopper 11 is fixedly connected with an expansion top frame 6 corresponding to the combination bottom frame 53. The inside of the mixer body 1 is fixedly connected with a material guide bucket 7 corresponding to the feed hopper 11. The layered feeding module 3 passes through the expansion top frame 6 and the feed hopper 11 to enter the material guide bucket 7 to perform unloading operation.

[0025] Two symmetrically distributed feed hoppers 11 are fixedly connected to the top of the mixer body 1. Materials enter the mixer body 1 through the feed hoppers 11 for mixing and stirring. A water inlet observation hopper 12 is fixedly connected to the top of the mixer body 1. The water inlet observation hopper 12 is located between the two feed hoppers 11. The operator can pour water into the mixer body 1 through the water inlet observation hopper 12, and at the same time, can observe the material mixing situation inside the mixer body 1 through the water inlet observation hopper 12 to improve the mixing effect.

[0026] The outer side of the mixer body 1 is fixedly connected with two loading and lifting frames 2 corresponding to the feed hoppers 11. The loading and lifting frames 2 are used to connect the corresponding layered loading modules 3 and drive the layered loading modules 3 to automatically approach the feed hoppers 11 at the corresponding positions on the mixer body 1 to perform automatic loading operations. The layered loading module 3 is connected to the inner side of the loading and lifting frame 2. The layered loading module 3 is composed of an outer frame 31, a transverse partition frame 32, a flipping support plate 33 and a positioning rod seat 34. The flipping support plate 33 is fixedly connected to the middle position of the bottom of the outer frame 31. There are two transverse partition frames 32. The two transverse partition frames 32 are fixedly connected to the inner side wall of the outer frame 31 from top to bottom in sequence. The flipping support plate 33 and the two transverse partition frames 32 are stably connected to the inside of the outer frame 31 from bottom to top in sequence.

The free end of the flip pallet 33 is located above the positioning rod seats 34. The four positioning rod seats 34 block the free end of the flip pallet 33 from below, thereby achieving the effect of positioning the free end of the flip pallet 33 from the bottom of the outer frame 31, and being able to position the free end of the flip pallet 33 inside the outer frame 31, thereby avoiding the free end of the flip pallet 33 from automatically rotating, so that the outer frame 31, the horizontal partition frame 32 and the flip pallet 33 form a complete layered loading module 3. Two transverse partition frames 32 separate the space between the outer frame 31 and the flip support plate 33 to form three material storage chambers 301. The three material storage chambers 301 are used to contain recycled aggregate, cement and sand respectively. The lower material storage chamber 301 contains recycled aggregate, and the positioned flip support plate 33 blocks and holds the recycled aggregate from below. The middle material storage chamber 301 contains cement, and the upper material storage chamber 301 contains sand, so as to facilitate the step-by-step stacking of recycled aggregate, cement and sand to form a stacking state of lower recycled aggregate, middle cement and upper sand. The top of the outer frame 31 can be connected to a cover to ensure that the material will not leak out during the automatic loading process of the layered loading module 3.

[0027] A loading assembly frame 4 is arranged above the layered loading module 3, and the loading assembly frame 4 is used to connect the loading lifting frame 2. The loading assembly frame 4 is composed of a drive chain assembly block 41, a combination top frame 42 and a fixed column 43. The fixed column 43 is fixedly connected to the bottom of the drive chain assembly block 41, and the other end of the fixed column 43 is fixedly connected to the outer wall of the combination top frame 42. The drive chain assembly block 41 is stably connected to the top of the combination top frame 42 through the fixed column 43, and the drive chain assembly block 41, the combination top frame 42 and the fixed column 43 are stably connected together. The combination top frame 42 is fixedly connected to the top of the outer frame 31, and the layered loading module 3 is stably connected to the bottom of the loading assembly frame 4. The drive chain assembly block 41 is engaged with the drive chain on the inner side of the loading lifting frame 2, which is convenient for the loading assembly frame 4 and the layered loading module 3 to be connected to the upper material lifting frame 2. The layered feeding module 3 can be integrally connected to the inner side of the feeding lifting frame 2 through the feeding assembly frame 4. Before automatic feeding, the lower layer of recycled aggregate, the middle layer of cement and the upper layer of sand are layered and stacked in the layered feeding module 3. The driving chain assembly block 41 connected to the driving chain carries the layered feeding module 3 as a whole on the inner side of the feeding lifting frame 2 and rises along with the driving chain, thereby achieving the effect of allowing the materials to form and maintain the stacking state of the lower layer of recycled aggregate, the middle layer of cement and the upper layer of sand during the automatic feeding process.

[0028] The top of the loading and lifting frame 2 is fixedly connected with a positioning and pushing module 5, which is composed of a fixed top plate 51, a first pushing driving member 52 and a combined bottom frame 53. The fixed top plate 51 is fixedly connected to the top of the loading and lifting frame 2, the first pushing driving member 52 is fixedly connected to the inner side of the fixed top plate 51, and the combined bottom frame 53 is fixedly connected to the output end of the first pushing driving member 52, so that the positioning and pushing module 5 is stably connected to the top of the loading and lifting frame 2. The loading and lifting frame 2 is provided with a clearance groove corresponding to the combined bottom frame 53, which provides a moving space for the combined bottom frame 53. At the same time, the combined bottom frame 53 corresponds to the outer side of the feed hopper 11, so that the combined bottom frame 53 can smoothly change its position in the area corresponding to the feed hopper 11 under the drive of the first pushing driving member 52, so that the combined bottom frame 53 can approach or move away from the feed hopper 11 while maintaining a uniform plane with the feed hopper 11. The layered loading module 3 can follow the drive chain to rise to the bottom of the combined chassis 53. At this time, the drive chain assembly block 41 is separated from the drive chain, and the drive chain assembly block 41 moves to the bottom of the combined chassis 53. The bottom end of the combined chassis 53 is fixedly connected with a plurality of clamping blocks 531, and the clamping blocks 531 are clamped together with the outer wall of the combined top frame 42. The bottom of the drive chain assembly block 41 is fixedly connected with an extended base support 411. The extended base support 411 supports the bottom end of the combined chassis 53 from below, and can position the drive chain assembly block 41 separated from the drive chain to be connected to the bottom end of the combined chassis 53. After loading to the area corresponding to the feed hopper 11, the drive chain assembly block 41 is separated from the drive chain, and the layered loading module 3 is positioned and connected to the position aligned with the feed hopper 11 through the cooperation of the combined top frame 42 and the clamping block 531, and the cooperation of the drive chain assembly block 41 and the combined bottom frame 53, so as to achieve the effect of reconnecting and positioning the layered loading module 3 in the area corresponding to the feed hopper 11 after the layered loading module 3 is separated from the loading lifting frame 2. The operation of the first push drive member 52 can make the layered loading module 3 as a whole approach the corresponding feed hopper 11, so as to facilitate the change of the position of the layered loading module 3 as a whole.

[0029] The top of the feed hopper 11 is fixedly connected to the expansion top frame 6 corresponding to the combined bottom frame 53, and the layered feeding module 3 as a whole can approach the expansion top frame 6 first under the drive of the first push drive member 52. The four outer corners of the outer frame 31 are slidably connected with side guide columns 311, and the four inner corners of the expansion top frame 6 are provided with guide grooves 61, and the side guide columns 311 are slidably connected with the corresponding guide grooves 61. The outer frame 31 approaches the expansion top frame 6, and the four side guide columns 311 enter the four guide grooves 61 before the outer frame 31, and the four side guide columns 311 cooperate with the four guide grooves 61 to guide the outer frame 31 to stably move toward the expansion top frame 6 and the feed hopper 11. The interior of the mixer body 1 is fixedly connected to a material guiding bucket 7 corresponding to the feed hopper 11. The outer frame 31 enters the expanded top frame 6 and continues to move, and directly enters the material guiding bucket 7 from the feeding end of the material guiding bucket 7 connected to the feed hopper 11, so that the layered loading module 3 can pass through the expanded top frame 6 and the feed hopper 11 and directly enter the material guiding bucket 7 to carry out unloading operations.

[0030] The layered loading module 3 as a whole is guided by the corresponding expansion top frame 6, passes through the expansion top frame 6 and the feed hopper 11 to enter the material guide bucket 7 in the mixer body 1, and the outer wall of the material guide bucket 7 is fixedly connected with four second material pushing driving members 71, and the four second material pushing driving members 71 correspond to the four positioning rod seats 34. After the layered loading module 3 stops moving, the positions of the four positioning rod seats 34 are respectively located on the inner sides of the output ends of the four second material pushing driving members 71, and the operation of the second material pushing driving member 71 can enable the output end of the second material pushing driving member 71 to push the columnar portion of the corresponding positioning rod seat 34, and the columnar portion moves inward, so that the columnar portion of the positioning rod seat 34 is staggered with the free end of the flipping support plate 33, thereby releasing the free end of the flipping support plate 33 and allowing the free end of the flipping support plate 33 to rotate. After the free end of the flip support plate 33 rotates, the material inside the material storage chamber 301 can be directly moved outward from the bottom of the outer frame 31, and the material is moved out from the outer frame 31 in a stacked state of the lower layer of recycled aggregate, the middle layer of cement, and the upper layer of sand, and is guided by the material guide bucket 7 to directly fall downward to the designated area inside the mixer body 1, so as to achieve the effect of stacking the material in steps and keeping the material in a stacked state for loading and positioning the material, which can improve the loading effect of the recycled aggregate for mixing and producing recycled aggregate concrete. The inner part of the outer frame 31 is fixedly connected with a vertical partition plate 312 located just above the flip support plate 33, and the vertical partition plate 312 separates the material storage chamber 301 and the placed material from the middle, so that the material can be discharged from the two areas to the inside of the mixer body 1, and at the same time, it can prevent the material from being blocked by the rotating cross bar in the middle area of ​​the flip support plate 33 to ensure layered discharge.

[0031] The working principle of the present invention is as follows: recycled aggregate, cement and sand are poured into the layered loading module 3 in sequence, the positioned flip support plate 33 blocks and supports the recycled aggregate from below, the middle material storage chamber 301 contains cement, and the upper material storage chamber 301 contains sand, and the recycled aggregate, cement and sand are stacked step by step to form a stacking state of a lower layer of recycled aggregate, a middle layer of cement and an upper layer of sand, the layered loading module 3 rises with the driving chain, the driving chain assembly block 41 is separated from the driving chain and moves to the bottom of the combined chassis 53, a number of clamping blocks 531 are clamped and connected to the outer side wall of the combined top frame 42, the extended bottom support 411 supports the bottom end of the combined chassis 53 from below, the driving chain assembly block 41 separated from the driving chain is positioned and connected to the bottom end of the combined chassis 53, the layered loading module 3 is positioned and connected to a position aligned with the feed hopper 11, and the first pushing drive member 52 operates to allow the layered loading module 3 to move as a whole. The corresponding feed hopper 11 approaches, and the four side guide columns 311 enter the four guide grooves 61 before the outer frame 31. The four side guide columns 311 and the four guide grooves 61 cooperate to guide the outer frame 31 and the flip pallet 33 along the expanded top frame 6 and the feed hopper 11 into the material guide bucket 7. After the layered feeding module 3 stops moving, the positions of the four positioning rod seats 34 are respectively on the inner sides of the output ends of the four second pushing drive members 71. The second pushing drive member 71 works to push the columnar portion of the corresponding positioning rod seat 34, so that the columnar portion of the positioning rod seat 34 is staggered with the free end of the flip pallet 33, and the free end of the flip pallet 33 rotates. The material is kept in the stacked state of the lower layer of recycled aggregate, the middle layer of cement, and the upper layer of sand and is moved out from the outer frame 31. It falls directly downward to the designated area inside the mixer body 1 under the guidance of the material guide bucket 7, and the mixer body 1 is started to stir and mix the material.
