[0047] The following will be combined with the 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.

[0048] For examples, see Figures 1 to 6, a prefabricated brick preparation device includes a mixing tank 1, and also includes: an intermittent feeding component, a stirring component and a discharging component, the intermittent feeding component is arranged at the top input end of the mixing tank 1, the stirring component is installed inside the mixing tank 1, and the discharging component is installed at the bottom output end of the mixing tank 1, and the prefabricated brick raw materials can be placed through the mixing tank 1, wherein a placement groove 24 is further provided on the side wall of the mixing tank 1, and the placement groove 24 is arranged circumferentially around the mixing tank 1, and the placement groove 24 is connected to the mixing tank 1 through a conveying hole, and the placement groove 24 is used to place raw materials with a relatively large amount of prefabricated bricks, such as clay, and the intermittent feeding component is used to place additives and other raw materials for configuring prefabricated bricks, such as shale and coal gangue and other powder additives. When in use, the main raw materials are continuously conveyed into the mixing tank 1 through the placement groove 24, and during the conveying process, the main raw materials are intermittently and continuously fed into the mixing tank 1 through the intermittent feeding component. Additives are transported in the mixing tank 1. As the main raw materials are continuously transported and transported layer by layer to the mixing tank 1, the additives are also filled into the main raw materials layer by layer, so that they are placed more evenly during mixing, thereby reducing subsequent stirring work. Compared with the traditional method of directly piling different raw materials in the mixing tank 1 and then stirring and mixing them all through the stirring mechanism, the stirring effect is improved and the uneven stirring is reduced. Among them, the types of raw materials placed in the placement trough 24 and the intermittent feeding component can be selected and used in combination with the actual dosage, as long as different materials can be contacted layer by layer. In order to improve the transportation effect of the raw materials in the placement trough 24 to the inside of the mixing tank 1, a plurality of pneumatic hammers 23 are installed at the bottom of the placement trough 24 to continuously knock the placement trough 24 to avoid blockage of raw material transportation. A water inlet pipe is also provided on the top of the mixing tank 1 to facilitate the transportation of water to the inside of the mixing tank 1.

[0049] In this embodiment, accordingly, the intermittent unloading component includes: a rotating barrel 2, a partition 3, a unloading hole 4 and a driving component. The rotating barrel 2 is rotatably installed on the top of the mixing tank 1, and the partition 3 divides the rotating barrel 2 into multiple unloading chambers. The unloading hole 4 is arranged at a position off-center at the top of the mixing tank 1, and the bottom of the unloading chamber is provided with a discharge hole 22 corresponding to the discharge hole 4. The driving component is arranged on the rotating barrel 2, and is used to drive the rotating barrel 2 to rotate. The rotating barrel 2 is driven to rotate by the driving component, and the partition 3 can be used to divide the rotating barrel 2 into different unloading chambers to facilitate the placement of different raw materials. During rotation, when the discharge hole 22 corresponds to the unloading hole 4, the corresponding raw material can be transported to the inside of the mixing tank 1 once, thereby realizing the phenomenon that the raw materials in the placement groove 24 and different materials are continuously superimposed and placed inside the mixing tank 1, so as to achieve a better mixing effect during stirring.

[0050] In this embodiment, correspondingly, the driving assembly includes: a motor 5, a driving gear 6 and a ring gear 7. The motor 5 is installed on the top of the mixing tank 1 through a bracket 19. A plurality of the driving gears 6 are equidistantly arranged on the outer circumference of the rotating barrel 2. The driving gear 6 is rotatably connected to the mixing tank 1. The ring gear 7 is fixedly mounted on the outer wall of the rotating barrel 2, and the driving gear 6 is meshed with the ring gear 7. The bottom output end of the motor 5 is concentrically connected to one of the driving gears 6. The driving gear 6 can be rotated by the motor 5. Under the meshing effect between the driving gear 6 and the ring gear 7, the rotation of the rotating barrel 2 can be realized, thereby achieving an intermittent unloading effect.

[0051] In this embodiment, accordingly, the stirring assembly includes: a main shaft 8, an auxiliary shaft 9 and a stirring blade 10. The main shaft 8 is rotatably arranged at the central axis position inside the mixing tank 1. The top of the main shaft passes through the top side wall of the mixing tank 1 and is concentrically connected to the bottom end of the rotating barrel 2. A plurality of auxiliary shafts 9 are equidistantly arranged on the outer circumference of the main shaft 8. The auxiliary shafts 9 correspond one-to-one to the driving gear 6, and the top of the auxiliary shaft 9 passes through the top side wall of the mixing tank 1 and is concentrically connected to the driving gear 6. Multiple groups of stirring blades 10 are installed on the outer walls of the main shaft 8 and the auxiliary shaft 9. Due to the arrangement of multiple driving gears 6 and the engagement of the driving gear 6 with the ring gear 7, the main shaft 8 and the auxiliary shaft 9 can be rotated simultaneously. The above-mentioned rotation effect drives the stirring blade 10 to rotate. Therefore, under the same drive assembly structure, the effects of simultaneous intermittent unloading and simultaneous stirring can be achieved. Moreover, stirring blades 10 are provided on both the main shaft 8 and the auxiliary shaft 9, which reduce the mixing dead angle inside the mixing tank 1 and improve the mixing effect between the raw materials.

[0052] In this embodiment, correspondingly, the discharge assembly includes: a discharge hopper 11 and a discharge plug 12. The discharge hopper 11 is connected and installed at the bottom end of the mixing tank 1. The discharge plug 12 is arranged at the upper side of the output end of the discharge hopper 11 through a reciprocating lifting mechanism. The reciprocating lifting of the reciprocating lifting mechanism enables the discharge plug 12 to be continuously closed and opened at the outlet of the discharge hopper 11, which can ensure that the raw materials are fully stirred inside the mixing tank 1 to avoid direct loss, and can also ensure that the mixed raw materials are intermittently or transported to the outside world in a certain amount, thereby basically achieving the purpose of quantitative discharge and improving the production efficiency of precast bricks.

[0053] In this embodiment, correspondingly, the reciprocating lifting mechanism includes: a reciprocating ring 13, a reciprocating block 14, a connecting rod 15 and a sliding rod 16. The reciprocating ring 13 is tilted and sleeved on the outer lower side of the main shaft 8. An opening is provided on one side of the reciprocating block 14, and the reciprocating block 14 is slidably provided on the reciprocating ring 13 through the opening. The reciprocating block 14 is connected to the discharge plug 12 through the connecting rod 15. The bottom end of the main shaft 8 is provided with a sliding hole, and the sliding rod 16 is slidably provided in the sliding hole. The bottom end of the sliding rod 16 is connected to the top end of the discharge plug 12. As the main shaft 8 rotates, the reciprocating ring 13 also rotates continuously. Under the sliding cooperation between the reciprocating blocks 14 and the sliding cooperation between the sliding rod 16 and the sliding hole, the reciprocating block 14 can drive the discharge plug 12 to move up and down continuously through the connecting rod 15, so as to achieve the purpose of continuously closing and opening the discharge plug 12 at the outlet of the discharge hopper 11, and achieve quantitative (each time the discharge plug 12 is pushed down, the discharge amount is basically the same, not absolutely quantitative) discharge and ensure that the raw materials inside the mixing tank 1 are fully stirred. Of course, a valve will be installed at the bottom of the discharge hopper 11 to ensure that the raw materials inside the mixing tank 1 are fully mixed before opening, and intermittent discharge can be carried out through the reciprocating action of the discharge plug 12.

[0054] In summary, when the prefabricated brick preparation device is used, the extrusion supporting equipment of the prefabricated brick is first installed on one side of the mixing tank 1. The extrusion supporting equipment of the prefabricated brick has a conveyor belt 17. The conveyor belt 17 is provided with a support block 22 for support to ensure subsequent extrusion. The lower mold 18 is placed on the conveyor belt 17. The lower mold 18 is intermittently transported to the bottom of the discharge hopper 11 through the conveyor belt 17. The extrusion equipment is installed on the output side of the conveyor belt 17. The extrusion equipment consists of a bracket 19 and a hydraulic cylinder 20. The bracket 19 and the mixing tank 1 are simultaneously erected on the same support base plate 21. The hydraulic cylinder 20 is installed on the bracket 19. The output end of the hydraulic cylinder 20 is equipped with a pressing plate 25. The pressing plate 25 is connected to the lower mold 1. 8 is used in conjunction with each other, and then different raw materials are placed in the placement trough 24 and multiple material discharge cavities. The water used can be transported to the inside of the mixing tank 1 through the water inlet pipe on the top of the mixing tank 1. As the motor rotates, the rotating barrel 2 is driven to rotate, so that the raw materials are continuously added to the mixing tank 1. At the same time, the stirring blades 10 are rotated to mix and stir them. The stirred raw materials continuously move downward to the discharge hopper 11, and the raw materials are transported to the lower mold 18 through the intermittent action of the discharge plug 12. After the lower mold 18 receives a certain amount of raw materials, it is transported to the bottom of the pressing plate 25 through the conveyor belt 17, and is pressed down by the hydraulic cylinder 20 to form bricks, and then sent to the drying and roasting process for subsequent processing.
