Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixing, and specifically relates to a concrete bunker proportioning and mixing device. Background Art

[0002] Concrete, abbreviated as "砼", refers to a general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as aggregates, and is mixed with water (which may contain additives and admixtures) in a certain proportion and stirred. It is widely used in civil engineering.

[0003] In the process of concrete production, it is necessary to mix and stir water, sand, stones, cement, etc. During the stirring process, due to the mechanical force and frictional force acting on the cement, the electrostatic force between cement particles increases, resulting in an adsorption force between cement particles, forming agglomerates. The agglomerated cement blocks are likely to affect the stirring effect and cause blockage of the discharge port. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title.

A lifting plate is provided between the stirring component and the crushing component inside the barrel body. After adding materials into the barrel body through the feeding port on the side wall of the barrel body, the stirring component is started to mix and stir the materials. During the stirring process, the stirring component pushes the lifting plate to move up and down. When the lifting plate moves upward, the agglomerates in the raw materials are pushed upward to the crushing component. When the crushing component crushes the agglomerates, the crushing component drives the water adding component to add water into the barrel body, making the cement particles in the barrel body wet, reducing the effect of electrostatic force, and reducing the continuous occurrence of agglomerates.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] This invention provides a concrete silo proportioning and mixing device. A water-adding component is installed at the top of the silo, a crushing component is installed near the top of the inner wall of the silo, and a mixing component is installed at the top of the silo, extending into the silo. A lifting plate is installed inside the silo between the mixing component and the crushing component. After materials are added to the silo through the inlet on the side wall of the silo, the mixing component is activated to mix the materials. During the mixing process, the mixing component pushes the lifting plate up and down. When the lifting plate moves upward, it pushes the clumps in the raw materials upward to the crushing component. When the crushing component crushes the clumps, it drives the water-adding component to add water to the inside of the silo, wetting the cement particles inside the silo, reducing the effect of static electricity, and reducing the continued formation of clumps.

[0039] Figure 1-10 The diagram shown is a structural schematic of one embodiment of a concrete silo proportioning and mixing device according to the present invention. Please refer to [link / reference]. Figures 1-10 The concrete silo proportioning and mixing device of this embodiment includes a barrel 100, a mixing component 200, a crushing component 300, a lifting plate 400, and a water adding component 500.

[0040] The barrel 100 has an opening at the top, and a top cover 110 is installed at the opening. An inlet 120 is installed on the outer wall of the barrel 100 near the top. An outlet 130 is installed on the outer wall of the barrel 100 near the bottom. A first fixed gear 140 is installed at the bottom of the barrel 100. A first fixed frame 150 is installed on the inner wall of the barrel 100. A first gear 150a is rotatably connected to the bottom of the first fixed frame 150. A threaded rod 150b is installed on the top of the first gear 150a, and the threaded rod 150b extends outwards from the first gear 150a. A first connecting rod 160 is installed on the top of a fixed frame 150 and on the inner wall of the barrel 100 below the first fixed frame 150. The other end of the first connecting rod 160 is rotatably connected to a roller 160a. The inlet 120 is located below the fixed plate 310 and the outlet 130 is located above the barrel 100. A sealing structure is provided at the joint between the first fixed frame 150 and the first turntable 240 to prevent concrete mix material from dripping from the joint to the position below the first fixed frame 150.

[0041] A mixing assembly 200 is installed on top of a tank 100 and extends into the tank 100 to mix the concrete raw materials entering the tank 100. The mixing assembly 200 includes a motor 210 installed on top of a top cover 110, a first rotating rod 220 installed at the output end of the motor 210 and extending into the tank 100, a third gear 230 installed at the bottom of the first rotating rod 220, a first turntable 240 installed on the body of the first rotating rod 220 and located within the inner ring of the first fixed frame 150, a fourth gear 250 located at the bottom of the tank 100 and meshing with the third gear 230, and a mixing rod 260 located on top of the fourth gear 250 and extending from the top of the first turntable 240. A second fixed gear disc 240a is installed at the bottom of the first turntable 240. A fixed gear 240a meshes with a first gear 150a, and a fourth gear 250 meshes with a first fixed gear 140. A first cross-shaped insert 250a is mounted on the top of the fourth gear 250. A stirring blade 260a is mounted on the top of the stirring rod 260. A first cross-shaped insert 260b is opened at the bottom of the stirring rod 260, and the first cross-shaped insert 250a extends into the first cross-shaped insert 260b. A conical block 260c is mounted at the bottom of the stirring rod 260, and a first spring 260d is mounted at the bottom of the conical block 260c. The height of the conical block 260c is flush with that of the first connecting rod 160. When the conical block 260c passes the roller 160a, the roller 160a presses the inclined side of the conical block 260c, pushing the conical block 260c downward. This is achieved by starting the motor 210. The first rotating rod 220 rotates, which in turn drives the third gear 230 to rotate. The third gear 230 then drives the fourth gear 250 to rotate. Since the first fixed gear disc 140 is fixed, the fourth gear 250 meshes with the first fixed gear disc 140 during its rotation. The fourth gear 250 revolves around the third gear 230. The rotation of the fourth gear 250 drives the first cross-shaped insert rod 250a to rotate, which in turn drives the stirring rod 260 and stirring blade 260a to rotate, thus mixing the concrete materials inside the barrel 100. When the fourth gear 250 revolves, it drives the stirring rod 260 and the conical block 260c to revolve. When the conical block 260c passes the bottom of the roller 160a, the roller 160a... The conical block 260c is pushed downwards by its inclined edge, compressing the first spring 260d. The conical block 260c then drives the stirring rod 260 and stirring blade 260a downwards. After the conical block 260c separates from the roller 160a, the first spring 260d rebounds, pushing the conical block 260c and stirring rod 260 upwards. Simultaneously, the stirring rod 260 and stirring blade 260a rotate, allowing them to move up and down, increasing the mixing efficiency of the concrete materials inside the bucket 100. When the first rotating rod 220 rotates, it drives the first turntable 240 to rotate. The first turntable 240 drives the second fixed gear disc 240a to rotate, and the second fixed gear disc 240a rotates, driving the first gear 150a to rotate.The top of the first turntable 240 is conical, which allows the raw material to move towards both ends of the turntable 240, facilitating the extraction of the concrete material through the discharge port 130.

[0042] The crushing assembly 300 is located inside the barrel 100 near the top of the barrel 100 to crush agglomerated raw materials. The crushing assembly 300 includes a fixed plate 310 installed on the inner wall of the barrel 100 near the top of the barrel 100, an arc-shaped groove 320 formed at the bottom of the fixed plate 310, a receiving groove 330 formed at the bottom of the fixed plate 310 and communicating with the arc-shaped groove 320, a crushing roller 340 rotatably connected inside the receiving groove 330, and an arc-shaped plate 350 located inside the arc-shaped groove 320. The top end of the threaded rod 150b is rotatably connected to the bottom of the fixed plate 310, and the arc-shaped plate 350... A second connecting rod 350a is installed at the top of the top of the 0-type top plate 110. A sixth gear 350b is installed at the top of the second connecting rod 350a. A fifth gear 340a is rotatably connected to the top of the fixed plate 310. The fifth gear 340a meshes with the sixth gear 350b. A second spring 350c is installed at the bottom of the sixth gear 350b. The first rotating rod 220 is located at the bottom of the top cover 110 and a second gear 220b is installed thereon. When the arc-shaped plate 350 moves upward inside the arc-shaped slide groove 320, the arc-shaped plate 350 pushes the second connecting rod 350a and the sixth gear 350b upward. Engaging with the second gear 220b, but not shown in detail in the figure, the sixth gear 350b is initially lower than the second gear 220b. The sixth gear 350b engages with the fifth gear 340a but is disengaged from the second gear 220b. When the lifting plate 400 pushes the agglomerated raw material upward, the agglomerated material abuts against the bottom of the arc-shaped plate 350. As the lifting plate 400 continues to push the agglomerated material upward, the agglomerated material squeezes the arc-shaped plate 350 upward inside the arc-shaped groove 320. The arc-shaped plate 350 pushes the second connecting rod 350a and the sixth gear 350b upward until... The sixth gear 350b meshes with the second gear 220b. As the first rotating rod 220 drives the second gear 220b to rotate, the second gear 220b drives the sixth gear 350b and the fifth gear 340a to rotate. The fifth gear 340a drives the crushing roller 340 to rotate. At this time, as the lifting plate 400 rotates, the clumps on the top of the lifting plate 400 move along the arc edge of the arc-shaped chute 320 toward the receiving groove 330. The clumps enter the receiving groove 330 along the arc edge and are crushed by the crushing roller 340. The crushed raw material powder falls into the barrel 100 through the receiving groove 330 to continue mixing and stirring.

[0043] The lifting plate 400 is located inside the barrel 100. When the stirring component 200 stirs, it drives the lifting plate 400 to move up and down, pushing the clumped raw materials inside the barrel 100 to the crushing component 300. The lifting plate 400 includes a second fixed frame 410 located inside the barrel 100, a second turntable 420 coaxially rotatably connected inside the second fixed frame 410, a slot 430 opened on the top of the second turntable 420, and a third fixed frame 440 hinged to the top of the slot 430. The top of the second fixed frame 410 has a threaded hole 410a, through which the threaded rod 150b rotates. The center of the top of the second turntable 420 has a... A sliding hole 420a is formed, through which a first rotating rod 220 passes. A limiting plate 220a is installed on the body of the first rotating rod 220. A limiting groove 420a-1 is formed on the inner wall of the sliding hole 420a, and the limiting plate 220a extends into the limiting groove 420a-1. A through hole 420b is formed at the top of the second turntable 420, and the position of the through hole 420b corresponds to the position of the stirring rod 260. A filter screen 440a is installed inside the third fixed frame 440. When the first gear 150a rotates, it drives the threaded rod 150b to rotate. When the threaded rod 150b rotates, it uses a screw structure to push the second fixed frame 410 to move the second turntable 420 upward. The limiting plate 220a extends into the limiting groove 420a-1. As the first rotating rod 220 rotates, the limiting plate 220a abuts against the inner wall of the limiting groove 420a-1. When the first rotating rod 220 rotates, the second turntable 420 rotates along with it, allowing the second turntable 420 to move up and down while rotating. The third fixing frame 440 can only rotate upwards on the second turntable 420. As the second fixing frame 410 drives the second turntable 420 to move downwards, the third fixing frame 440 flips upwards, opening the slot 430. When the second turntable 420 moves downwards, raw materials and lumps enter the second turntable 420 through the slot 430. At the upper position, when the second fixed frame 410 drives the second turntable 420 to move upward, the third fixed frame 440 closes. As the second turntable 420 moves upward, the raw material enters the position below the second turntable 420 through the filter screen 440a. The filter screen 440a filters out the lumps in the raw material and accumulates them on the top of the second turntable 420. As the second turntable 420 moves upward, when the top of the lumps abuts against the bottom of the fixed plate 310, the lumps roll into the arc-shaped chute 320 as the second turntable 420 rotates. As the second turntable 420 rotates, the lumps slide along the arc plate inside the arc-shaped chute 320 into the receiving groove 330.

[0044] A water-adding assembly 500 is installed on top of the barrel 100 and connected to the crushing assembly 300. When the crushing assembly 300 crushes the agglomerated raw materials, it drives the water-adding assembly 500 to add water into the barrel 100. The water-adding assembly 500 includes a housing 510 installed on top of the top cover 110, a vertical plate 520 installed on top of the top cover 110, a piston 530 located inside the housing 510, and a water tank 540 installed on top of the housing 510. A first conveying pipe 510a is installed on the side wall of the housing 510, and the other end of the first conveying pipe 510a is connected to the water tank 540. A first one-way valve 510a-1 is installed on the body of the first conveying pipe 510a. A second conveying pipe 510b is installed on the side wall of the housing 510. The second conveying pipe 510b... One end is connected to the inside of the barrel 100. A second one-way valve 510b-1 is installed on the body of the second conveying pipe 510b. A reciprocating threaded rod 520a is rotatably connected to the side wall of the vertical plate 520. One end of the reciprocating threaded rod 520a extends out of the side wall of the vertical plate 520 and is equipped with a first helical gear 520a-1. A second helical gear 520b is rotatably connected to the top of the top cover 110. The second helical gear 520b meshes with the first helical gear 520a-1. A second rotating rod 520b-1 is installed at the bottom of the second helical gear 520b. A second cross slot 520b-2 is opened at the bottom end of the second rotating rod 520b-1. A second cross insert 350b-1 is installed on the top of the sixth gear 350b. The second cross insert 350b-1 extends into the second cross slot 520b-1. Inside 0b-2, a fixing rod 530a is installed on the side wall of piston 530. A reciprocating threaded hole 530b is opened at the side end of the fixing rod 530a. The reciprocating threaded rod 520a rotates and extends into the reciprocating threaded hole 530b. When the agglomerated arc plate 350 slides upward inside the arc groove 320, the second cross-shaped insert rod 350b-1 slides inside the second cross-shaped slot 520b-2 until the sixth gear 350b meshes with the second gear 220b. At this time, the sixth gear 350b rotates with the second gear 220b, driving the second cross-shaped insert rod 350b-1 to rotate, which in turn drives the second rotating rod 520b-1 and the second helical gear 520b to rotate. The second helical gear 520b drives the first helical gear 520a-1 and... The reciprocating threaded rod 520a rotates, and during this rotation, the screw structure drives the fixed rod 530a, which in turn drives the piston 530 to reciprocate inside the housing 510. When the piston 530 moves outward from the housing 510, the first one-way valve 510a-1 opens and the second one-way valve 510b-1 closes. Water from the water tank 540 enters the housing 510 through the first delivery pipe 510a. As the piston 530 moves inward from the housing 510, the first one-way valve 510a-1 closes and the second one-way valve 510b-1 opens. Water from the housing 510 is then delivered to the bucket 100 through the second delivery pipe 510b, adding water to the concrete raw materials and wetting the cement particles inside the bucket 100, thus reducing the effect of static electricity.Reduce the occurrence of further clumping.

[0045] Combination Figures 1-10This embodiment of a concrete silo proportioning and mixing device involves adding materials such as water, sand, gravel, and cement into a container 100 through an inlet 120. A motor 210 is started, driving a first rotating rod 220 and a third gear 230 to rotate. The third gear 230 drives a fourth gear 250 to rotate. While the fourth gear 250 rotates, it is fixed by a first fixed gear disc 140. As the third gear 230 rotates, the fourth gear 250 revolves simultaneously, driving a mixing rod 260 and a mixing blade 260a to rotate, thus mixing the concrete raw materials inside the container 100. During mixing, the first rotating rod 220 drives a first rotating disc 240 to rotate, which in turn drives a second fixed gear disc 240a to rotate. 240a meshes with the first gear 150a, driving the first gear 150a and the threaded rod 150b to rotate. When the threaded rod 150b rotates, it uses a screw structure to push the second fixed frame 410 to drive the second turntable 420 to move upward. As the first rotating rod 220 rotates, the limiting plate 220a follows the first rotating rod 220 to rotate, and drives the second turntable 420 to rotate. The concrete raw material enters below the second turntable 420 through the filter screen 440a. At this time, the lumps inside the concrete raw material are filtered out by the filter screen 440a and accumulate at the top of the second turntable 420. As the second turntable 420 moves upward until the lumps contact the bottom of the fixed plate 310, the second turntable 420 rotates and drives the lumps to roll into the arc-shaped chute 320. The rotating disc 420 pushes the agglomerates along the arc-shaped edge of the arc-shaped chute 320 into the receiving groove 330. As the second rotating disc 420 continues to move the agglomerates upward, the agglomerates compress the arc-shaped plate 350, causing it to move upward within the arc-shaped chute 320 and compress the second spring 350c. The arc-shaped plate 350 drives the second connecting rod 350a and the sixth gear 350b upward until the sixth gear 350b meshes with the second gear 220b. At this point, the first rotating rod 220 drives the second gear 220b to rotate, which in turn drives the sixth gear 350b and the fifth gear 340a to rotate. This, in turn, drives the crushing roller 340 to rotate, crushing the agglomerates inside the receiving groove 330. The crushed agglomerate powder falls into the barrel 100 and continues to be stirred. As the sixth gear 350b moves upward and meshes with the second gear 220b, its rotation drives the second cross-shaped insert rod 350b-1 to rotate. The second cross-shaped insert rod 350b-1 then drives the second rotating rod 520b-1 and the second helical gear 520b to rotate. The second helical gear 520b drives the first helical gear 520a-1 and the reciprocating threaded rod 520a to rotate. The reciprocating threaded rod 520a uses a screw mechanism to push the fixed rod 530a, causing the piston 530 to reciprocate inside the housing 510. When the piston 530 moves outward from the housing 510, the first one-way valve 510a-1 opens, and the second one-way valve 510b-1 closes. Water from the water tank 540 enters the housing 510 through the first delivery pipe 510a.As piston 530 moves into housing 510, the first one-way valve 510a-1 closes and the second one-way valve 510b-1 opens. Water inside housing 510 is transported to the inside of barrel 100 through second delivery pipe 510b, adding water to the concrete raw materials and wetting the cement particles inside barrel 100, reducing the effect of static electricity and preventing further clumping. When no clumping occurs in the raw materials inside barrel 100, as the second turntable 420 rises, the raw materials, after being filtered by filter screen 440a, enter the position below the second turntable 420. At this time, since there are no clumping in the raw materials, there is no clumping accumulation on the top of the second turntable 420. As the second turntable 420 moves upward until its top abuts against the bottom of fixed plate 310, since there is no clumping accumulation on the top of the second turntable 420, the arc plate 350 will not move upward inside the arc groove 320. Therefore, the sixth gear 350b and the second gear 220... When the crushing roller 340 does not rotate, and the second helical gear 520b does not rotate with the sixth gear 350b, the water supply component 500 will not add water to the raw materials inside the barrel 100. However, when there are lumps in the concrete raw materials inside the barrel 100, as the second turntable 420 rises, the lumps are filtered out and accumulate on top of the second turntable 420. As the second turntable 420 moves upward, it pushes the lumps upward against the arc-shaped plate 350 within the arc-shaped groove 320, causing the sixth gear 350b to mesh with the second gear 220b. The second helical gear 520b rotates with the sixth gear 350b, indicating that the raw materials inside the barrel 100 are now lumpy and require water addition. When the second helical gear 520b rotates, it drives the piston 530 to reciprocate within the housing 510, transferring water from the water tank 540 to the barrel 100 for water addition, preventing further lumping.
