For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] As Figures 1-7 shown, a door leaf casting and discharging device includes a storage mechanism 1 for storing concrete, a mixing mechanism 2 for mixing concrete during hoisting, and a discharging mechanism 3 for controlling discharging. A plurality of hoisting rings 4 are uniformly installed on the outer side of the top of the storage mechanism 1. The mixing mechanism 2 is installed inside the storage mechanism 1, and the discharging mechanism 3 is arranged at the discharging position at the bottom of the storage mechanism 1;
[0031] The storage mechanism 1 includes a storage barrel 11. A funnel 12 is arranged at the bottom of the storage barrel 11, and a discharge pipe is arranged at the bottom of the funnel 12. The mixing mechanism 2 includes a support ring 21. The support ring 21 is of a ring structure and is closely attached to the inner wall of the storage mechanism 1. Two support rings 21 are arranged inside the storage barrel 11. The inner side of the top support ring 21 is installed with a top stirring rod 22. There are four top stirring rods 22, and the four top stirring rods 22 intersect at the axis position of the storage barrel 11, and the four top stirring rods 22 are inclined upward to form a conical structure. A power ring 24 is arranged at the bottom of the support ring 21. The power ring 24 is located at the junction of the storage barrel 11 and the funnel 12. A plurality of scrapers 23 are connected in series between the support ring 21 and the power ring 24. The scrapers 23 are arranged vertically along the storage barrel 11 and are arranged in an array along the inner wall of the storage barrel 11. A power assembly for driving the mixing mechanism 2 to rotate is arranged outside the storage barrel 11 corresponding to the position of the power ring 24. A bottom scraper 26 is installed inside the funnel 12 at the bottom of the power ring 24, and an inner stirring rod 25 is installed inside the lower support ring 21 and the power ring 24;
[0032] The discharging mechanism 3 includes a valve disc 33 which is arranged inside the discharging pipe. The valve disc 33 is horizontally connected to an external turntable 31 through a main shaft 32, and a counterweight 34 is installed on the turntable 31.
[0033] In this embodiment, the power assembly of the mixing mechanism 2 includes a power gear ring 242. A ring groove is formed on the outer circumferential surface of the power ring 24, and the power gear ring 242 is installed in the ring groove. A power gear 241 is fitted inside the power gear ring 242, and the power rod of the power gear 241 extends out of the storage barrel 11 and is connected to a power motor set 243 located outside the storage barrel 11.
[0034] In this embodiment, a fixed disc 35 is arranged outside the discharging pipe of the storage mechanism 1 corresponding to the position of the main shaft 32. A limit bead 351 is arranged on the main shaft 32 corresponding to the position of the fixed disc 35. A groove for receiving the limit bead 351 is formed on the main shaft 32, and a spring for supporting the limit bead 351 is installed in the groove. A ball groove is formed on the fixed disc 35 corresponding to the position of the limit bead 351, and the limit bead 351 is limited by the ball groove, so that there is a resistance when the main shaft 32 and the valve disc 33 are in the closed state, avoiding the phenomenon of accidental opening.
[0035] In this embodiment, the internal stirring rod 25 is in a straight state, and the internal stirring rod 25 is connected to the support ring 21 and the power ring 24 by welding to ensure the firmness of the structure.
[0036] In this embodiment, the power ring 24 is connected to the scraping plate 23 and the bottom scraping plate 26 by welding.
[0037] In this embodiment, the main shaft 32 is connected to the fixed disc 35 through a sealed bearing.
[0038] In this embodiment, a fixing ring is welded at the bottom of the bottom scraping plate 26 at the positions of the funnel 12 and the discharging pipe, and the bottom scraping plate 26 is slidably connected to the inner wall of the funnel 12.
[0039] Working principle: The device is moved to the position of the concrete truck or the concrete station through the lifting ring 4. When pouring concrete into the storage barrel 11, because the top stirring rod 22 has an inclined upward structure, the concrete impacts on the top stirring rod 22, and the top stirring rod 22 has a tendency to expand outwards. Thus, the top stirring rod 22 is supported on the inner wall of the storage barrel 11 through the support ring 21, forming an effect that the top stirring rod 22 and the support ring 21 cooperate to lock the inner wall of the storage barrel 11, avoiding the structural damage of the mixing mechanism 2 caused by the continuous impact of the concrete.
[0040] After the pouring is completed, the whole device is driven to move by the hoisting equipment. When it moves to the upper end of the door panel mold, the worker manually rotates to open the turntable 31 and the valve disc 33, so that the concrete is poured into the mold. At this time, the worker starts the power motor set 243 by observing the outflow of the concrete to stir the concrete inside. During the long hoisting process, the concrete materials inside will accumulate to a certain extent, with the heavy ones sinking and the light ones floating. At this time, the power motor set 243 can be started. The power motor set 243 drives the power gear 241 to cooperate with the power gear ring 242, so that the power ring 24 rotates. The power ring 24 drives the upper and lower support rings 21, the top stirring rod 22 and the bottom scraper 26 through the scraper 23, turning the materials near the outside inward and the materials in the center, thus improving the mixing degree of the concrete materials;
[0041] And after pouring a certain amount of materials, because the concrete is viscous, the power motor set 243 can also be started to scrape the inner wall through the scraper 23, avoiding adhesion and improving the use efficiency of the materials at the same time;
[0042] The main shaft 32 at the bottom has a tendency to rotate driven by the counterweight 34 on the turntable 31, and the counterweight 34 can also remind the worker to close the valve disc 33 in time. When the valve disc 33 is closed, the limit bead 351 on the main shaft 32 just gets stuck in the ball groove on the inner wall of the fixed disc 35, giving the main shaft 32 a certain self-locking property to prevent the valve disc 33 from being accidentally opened by the vibration during the movement of the device.
[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
