Description

Technical Field

[0001] The utility model belongs to the technical field of concrete batching machines for concrete production, and particularly relates to a concrete batching machine for environmentally friendly concrete production. Background Technique

[0002] Concrete, abbreviated as "砼", is one of the most important civil engineering materials in modern times. Concrete is a kind of artificial material prepared by mixing cementitious materials, granular aggregates, water, and additives and admixtures added as necessary in a certain proportion, and formed through uniform stirring, dense molding, and curing and hardening. Concrete has the characteristics of high compressive strength, good durability, and a wide range of strength grades, which make concrete widely used in various fields;

[0003] Concrete is usually configured and stirred using a batching machine, but the concrete mixture is likely to adhere to the stirring blades and the inner wall of the batching machine. The concrete adhering to the stirring blades and the inner wall of the batching machine requires additional time and labor for cleaning, which affects the working efficiency of the batching machine. To solve this problem, we have proposed a concrete batching machine for environmentally friendly concrete production. Summary of the Invention

[0004] The purpose of the utility model is to provide a concrete batching machine for environmentally friendly concrete production. By setting a stirring component, specifically starting the motor, the rotating shaft rotates. The rotating shaft will drive the scraper to rotate through the first connecting part and the connecting rod. When the scraper rotates, it will scrape the concrete adhering to the inner wall of the stirring tank through its outer surface. The rotating shaft will also drive the folding blades to rotate through the second connecting part and stir the raw materials. When the stirring component finishes stirring, the rotating shaft gradually stops rotating, and the folding blades of the first connecting part will also gradually hang down under the action of gravity, and the concrete adhering to the folding blades will be thrown onto the funnel-shaped inclined plane. In this way, the stirring component can clean the inside of the stirring tank of the mixer, preventing the concrete from solidifying and affecting the subsequent production. It solves the problem that existing concrete is usually configured and stirred using a batching machine, but the concrete mixture is likely to adhere to the stirring blades and the inner wall of the batching machine, and the concrete adhering to the stirring blades and the inner wall of the batching machine requires additional time and labor for cleaning, which affects the working efficiency of the batching machine.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a concrete batching machine for environmentally friendly concrete production, including a stirrer. The stirrer includes a stirring tank body and a stirring tank cover, and a stirring component is arranged inside the stirrer;

[0007] The stirring assembly includes a rotating shaft that passes through the top of the stirrer cover and extends outward. The rotating shaft is rotatably connected to the stirrer cover. A motor is fixedly connected to the center of the top of the stirrer cover. The output end of the motor is fixedly connected to the top of the rotating shaft via a coupling. Two connecting parts are fixedly connected to the outer surface of the rotating shaft. The two connecting parts are arranged in a longitudinal array around the rotating shaft. Three scrapers are arranged on the side of the connecting parts away from the rotating shaft. The three scrapers are arranged in a circumferential array around the rotating shaft. The outer surface of the scrapers contacts the inner surface of the stirrer tank. Below the two connecting parts... Each component is equipped with a second connector. The inner surface of the second connector is fixedly connected to the outer surface of the rotating shaft. The bottom of the second connector has three slots, which are arranged in a circular array around the rotating shaft. Folded blades are rotatably connected inside the slots. The scraper can stir the raw materials, and through the contact between the outer surface of the scraper and the inner surface of the mixer tank, the raw materials attached to the inner surface of the mixer tank can be scraped off. When the rotating shaft gradually stops rotating, the folded blades will gradually fall downwards under the influence of their own gravity, and the concrete attached to the folded blades will be thrown to the bottom of the mixer tank.

[0008] Furthermore, the stirrer is internally equipped with an auxiliary component and a connecting member three. The auxiliary component includes three stirring blades, which are positioned between the upper connecting member two and the lower connecting member one. The three stirring blades are fixedly connected to the outer surface of the rotating shaft on the side closest to the rotating shaft. The three stirring blades are arranged in a circumferential array around the rotating shaft. The connecting member three is located at the bottom of the rotating shaft, and its inner surface is fixedly connected to the outer surface of the bottom of the rotating shaft. The outer surface of the connecting member three is provided with several V-shaped blades. When the V-shaped blades rotate, they generate vortices. These vortices enhance the interaction between the raw materials at the top and bottom, allowing the raw materials deposited at the bottom to circulate upwards.

[0009] Furthermore, the agitator includes an agitator tank, which is located at the bottom of the agitator top cover. The top of the agitator tank contacts the bottom of the agitator top cover. Flanges are fixedly connected to both the top of the agitator tank and the bottom of the agitator top cover. Four irregularly shaped protrusions are fixedly connected to the outer surface of the flanges. The four irregularly shaped protrusions and the flanges are arranged in a circumferential array around the agitator tank. Threaded holes are opened at the center of each of the four irregularly shaped protrusions. The agitator tank and the agitator top cover are fixedly connected by bolts passing through the threaded holes. The flanges are used to connect the agitator tank and the agitator top cover, ensuring the sealing and structural integrity of the agitator tank. The flange connection makes the disassembly and installation between the agitator tank and the agitator top cover relatively easy, facilitating cleaning, maintenance, and replacement of parts inside the agitator tank.

[0010] Furthermore, the bottom of the mixer tank is provided with a funnel-shaped inclined surface, and a discharge hopper is provided at the bottom of the mixer tank. The discharge hopper has a bottom discharge valve, and three support columns are fixedly connected to the bottom of the mixer tank. The three support columns are arranged in a circumferential array with the mixer tank as the center. The funnel-shaped inclined surface facilitates the guidance of the mixed concrete into the discharge hopper. The discharge valve can control the discharge from the discharge hopper, and the support columns can provide support for the mixer tank.

[0011] Furthermore, three sets of connecting components are provided on the side of the two connecting parts away from the outer surface of the rotating shaft. The three sets of connecting components are arranged in a circumferential array with the rotating shaft as the center. Each set of connecting components includes two connecting rods, which are arranged in a longitudinal array with the rotating shaft as the center. The connecting rod located above is fixedly connected to the outer surface of the connecting part located above, and the connecting rod located below is fixedly connected to the outer surface of the connecting part located below. The side of the scraper close to the connecting part is fixedly connected to the side of the connecting component away from the connecting part. When the rotating shaft drives the connecting part to rotate, the connecting part will also drive the three scrapers to rotate through the three sets of connecting components fixed on its outer surface.

[0012] Furthermore, a circular hole is provided at the top of the folding blade, and a pin is rotatably connected to the circular hole at the top of the folding blade. The pin passes through the second connector and extends outward. The pin is rotatably connected to the second connector and is located at the connection between the second connector and the folding blade, forming a hinge. This connection method allows the folding blade to rotate to a certain extent.

[0013] Furthermore, a turntable is fixedly connected to the outer surface of the connector three. The turntable is fixedly connected to several V-shaped blades. The several V-shaped blades are arranged in a circumferential array with the rotation axis as the center. When the motor drives the rotation axis to rotate, the rotation axis will drive the turntable to rotate through the connector three at the bottom. When the turntable rotates, it will also drive the several V-shaped blades to rotate.

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

[0015] This invention utilizes a mixing assembly. Specifically, starting the motor causes the rotating shaft to rotate. The rotating shaft, through a connecting member and a connecting rod, drives the scraper to rotate. As the scraper rotates, it scrapes away the concrete adhering to the inner wall of the mixer tank from its outer surface. The rotating shaft, through a connecting member, also drives the folded blades to rotate and mix the raw materials. When the mixing assembly stops mixing, the rotating shaft gradually stops rotating, and the folded blades of the connecting member gradually droop under gravity, throwing the concrete adhering to the folded blades onto the funnel-shaped inclined surface. In this way, the mixing assembly cleans the inside of the mixer tank, preventing the concrete from solidifying and affecting subsequent production.

[0016] This invention incorporates an auxiliary component: when the motor drives the rotating shaft, the three mixing blades fixedly connected to the outer surface of the rotating shaft also rotate together, enhancing convection between the upper and lower folded blades and further improving the mixing effect. Larger materials may deposit along the funnel-shaped slope to the bottom of the mixer tank. When the rotating shaft drives the folded blades to rotate, a vortex is generated, allowing the raw materials deposited at the bottom to circulate upwards through the vortex. This assists the mixing component, improving its mixing effect on concrete raw materials and enhancing the quality of the concrete mixture.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-6 As shown, this utility model is a concrete batching machine for environmentally friendly concrete production, including a mixer 1. The mixer 1 includes a mixer tank 11 and a mixer top cover 12. A mixing component 2 is provided inside the mixer 1.

[0029] The stirring assembly 2 includes a rotating shaft 211, which passes through the top of the stirrer top cover 12 and extends outward. The rotating shaft 211 is rotatably connected to the stirrer top cover 12. A motor 212 is fixedly connected to the center of the top of the stirrer top cover 12. The output end of the bottom of the motor 212 is fixedly connected to the top of the rotating shaft 211 via a coupling. Two connecting parts 1 221 are fixedly connected to the outer surface of the rotating shaft 211. The two connecting parts 1 221 are arranged in a longitudinal array with the rotating shaft 211 as the center. Three scrapers 223 are arranged on the side of the connecting parts 1 221 away from the rotating shaft 211. The three scrapers 223 are arranged in a circumferential array with the rotating shaft 211 as the center. The outer surface of the scrapers 223 contacts the inner surface of the stirrer tank 11. A connecting part 231 is arranged below each of the two connecting parts 1 221. The inner surface of the connecting part 231 is fixedly connected to the outer surface of the rotating shaft 211. Three slots are opened at the bottom of the connecting part 231. The slots at the bottom of connector 231 are arranged in a circular array around the rotating shaft 211. Folded blades 232 are rotatably connected inside the slots. By setting up the mixing assembly 2, specifically by starting the motor 212, the rotating shaft 211 is rotated. The rotating shaft 211 drives the scraper 223 to rotate through connector 221 and connecting rod 222. When the scraper 223 rotates, it scrapes off the concrete adhering to the inner wall of the mixer tank 11 through its outer surface. The rotating shaft 211 also drives the folded blades 232 to rotate through connector 231 and mix the raw materials. When the mixing assembly 2 stops mixing, the rotating shaft 211 gradually stops rotating, and the folded blades 232 of connector 2 gradually droop under the action of gravity, throwing the concrete adhering to the folded blades 232 onto the funnel-shaped inclined surface 14. In this way, the mixing assembly 2 can clean the inside of the mixer tank 11 and prevent the concrete from solidifying and affecting subsequent production.

[0030] The stirrer 1 is internally equipped with an auxiliary component 3 and a connecting member 321. The auxiliary component 3 includes three stirring blades 31, which are positioned between the upper connecting member 231 and the lower connecting member 1 221. The side of the three stirring blades 31 closest to the rotating shaft 211 is fixedly connected to the outer surface of the rotating shaft 211. The three stirring blades 31 are arranged in a circular array around the rotating shaft 211. The connecting member 321 is located at the bottom of the rotating shaft 211, and its inner surface is fixedly connected to the outer surface of the bottom of the rotating shaft 211. The outer surface of the connecting member 321 is provided with several V-shaped blades 323. Auxiliary component 3, specifically, when the motor 212 drives the rotating shaft 211 to rotate, the three mixing blades 31 fixedly connected to the outer surface of the rotating shaft 211 will also rotate together, enhancing the convection between the upper and lower folded blades 232, further improving the mixing effect. Meanwhile, materials with larger masses may be deposited along the funnel-shaped inclined surface 14 to the bottom of the mixer tank 11. When the rotating shaft 211 drives the folded blades 232 to rotate, a vortex is generated, and the raw materials deposited at the bottom will circulate upward through the vortex. This can assist the mixing of the mixing component 2, improve the mixing effect of the mixing component 2 on concrete raw materials, and improve the mixing quality of concrete.

[0031] The mixer 1 includes a mixer tank 11, which is located at the bottom of the mixer top cover 12. The top of the mixer tank 11 contacts the bottom of the mixer top cover 12. Both the top of the mixer tank 11 and the bottom of the mixer top cover 12 are fixedly connected to flanges 131. Four irregularly shaped protrusions 132 are fixedly connected to the outer surface of the flanges 131. The four irregularly shaped protrusions 132 and the flanges 131 are arranged in a circumferential array with the mixer tank 11 as the center. Threaded holes 133 are opened at the center of each of the four irregularly shaped protrusions 132. The mixer tank 11 and the mixer top cover 12 are fixedly connected by bolts passing through the threaded holes 133.

[0032] The bottom of the agitator tank 11 is provided with a funnel-shaped inclined surface 14, the bottom of the agitator tank 11 is provided with a discharge hopper 15, the bottom of the discharge hopper 15 is provided with a discharge valve 16, and the bottom of the agitator tank 11 is fixedly connected with three support columns 17, which are arranged in a circular array around the agitator tank 11.

[0033] Three sets of connecting components are provided on the side of the two connectors 221 away from the outer surface of the rotating shaft 211. The three sets of connecting components are arranged in a circumferential array with the rotating shaft 211 as the center. Each set of connecting components includes two connecting rods 222. The two connecting rods 222 are arranged in a longitudinal array with the rotating shaft 211 as the center. The connecting rod 222 located above is fixedly connected to the outer surface of the connector 221 located above, and the connecting rod 222 located below is fixedly connected to the outer surface of the connector 221 located below. The side of the scraper 223 close to the connector 221 is fixedly connected to the side of the connecting component away from the connector 221.

[0034] The outer surface of the scraper 223 contacts the inner surface of the agitator tank 11. A round hole is opened at the top of the folded blade 232. A pin 233 is rotatably connected to the round hole at the top of the folded blade 232. The pin 233 passes through the connector 231 and extends outward. The pin 233 is rotatably connected to the connector 231.

[0035] A turntable 322 is fixedly connected to the outer surface of connector 321. The turntable 322 is fixedly connected to several V-shaped blades 323, which are arranged in a circular array around the rotation axis 211.

[0036] One specific application of this embodiment is: pouring the raw materials of concrete into the interior of the mixer tank 11 through the opening at the top of the mixer tank 11, and then using bolts to pass through the threaded holes 133 to fix the mixer tank 11 to the mixer top cover 12.

[0037] After the mixer tank 11 and the mixer top cover 12 are fixed, the motor 212 is started to put the mixing assembly 2 into working state. The motor 212 will drive the rotating shaft 211 to rotate through the coupling. When the rotating shaft 211 rotates, it will drive the first connector 221 and the second connector 231 to rotate. When the second connector 231 rotates, it will drive the scraper 223 to rotate through the connecting rod 222 fixedly connected to the outer surface. When the second connector 231 rotates, the folding blade 232 connected to the second connector 231 will unfold under the action of centrifugal force, so that the folding blade 232 is perpendicular to the rotating shaft 211 and forms a stable mixing state to mix the raw materials.

[0038] When the rotating shaft 211 rotates, the auxiliary component 3 will also enter the working state. When the rotating shaft 211 rotates, it will drive several stirring blades 31 to rotate. When the rotating shaft 211 rotates, it will drive the connecting part 321 at the bottom to rotate. The connecting part 321 will drive the turntable 322 to rotate. When the turntable 322 rotates, it will drive several V-shaped blades 323 to rotate, causing a vortex to be generated at the bottom of the mixer tank 11, which will promote the mixing effect of the stirring component 2.

[0039] After the stirring is completed, the motor 212 stops the rotating shaft 211 from rotating, allowing the stirring assembly 2 and the auxiliary assembly 3 to stop working. As the rotating shaft 211 gradually stops rotating, the folding blades 232 will droop and retract under their own weight, making the folding blades 232 horizontal with the rotating shaft 211.

[0040] Then, by operating the handle to open the discharge valve 16, the mixed concrete will flow along the funnel-shaped inclined surface 14 at the bottom of the mixer tank 11 to the discharge hopper 15, and finally enter the discharge valve 16 to be discharged.
