Description

Technical Field

[0001] This invention belongs to the field of civil engineering technology, and specifically relates to a high-efficiency mixing device for civil engineering. Background Technology

[0002] Civil engineering is a general term for the science and technology of constructing various land engineering facilities. It refers not only to the materials and equipment used and the technical activities such as surveying, design, construction, maintenance, and repair, but also to the objects of engineering construction. With the advancement of science and technology and the development of engineering practice, civil engineering has developed into many branches, such as housing engineering, railway engineering, road engineering, airport engineering, bridge engineering, tunnel and underground engineering, special engineering structures, water supply and drainage engineering, urban heating and gas supply engineering, port engineering, and water conservancy engineering.

[0003] Concrete is frequently used in civil engineering construction. Concrete is made by mixing multiple materials. Currently, the production process of concrete generally involves using excavators or other loaders to pour all the materials into or continuously feed the concrete materials into a mixer for mixing. However, this feeding method causes the materials to accumulate in the mixer, making it difficult to mix evenly quickly after starting the mixer. It requires the mixer to mix for a long time, resulting in a relatively low rate of uniform concrete mixing. Therefore, a high-efficiency mixing device for civil engineering is proposed to solve the above problems. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a high-efficiency mixing device for civil engineering, which enables materials to be intermittently introduced into a first mixing tank for stirring and mixing during the concrete preparation process. This allows the materials that have entered the first mixing tank beforehand to be fully mixed, avoiding the accumulation caused by all materials entering the first mixing tank at the same time, improving the mixing uniformity between materials, and also increasing the mixing rate.

[0021] Compared with the prior art, the high-efficiency mixing device for civil engineering of the present invention has the following advantages:

[0022] 1. In the concrete production process, the material is first added to the trough. The material enters the guide channel through the discharge pipe. As the material falls into the guide channel, the linear reciprocating component drives the moving block to move the baffle back and forth. The inlet on the guide channel opens and closes alternately due to the reciprocating motion of the baffle, allowing the material to enter the guide channel intermittently. Then, the material is intermittently transported to the first mixing tank for mixing. This ensures that the material that has entered the first mixing tank beforehand can be fully mixed, avoiding the accumulation caused by all the material entering the first mixing tank at the same time. This improves the mixing uniformity between the materials and also increases the mixing rate.

[0023] 2. In this device, the second mixing tank serves as the material transfer channel between the holding trough and the guiding channel. The material is pre-entered into the second mixing tank. At this time, the drive component drives the rotating shaft to rotate, which in turn drives the second sprocket to rotate. The second sprocket, through a chain, cooperates with the first sprocket to drive the second mixing tank to rotate. During the rotation of the second mixing tank, the first stirring rod inside can stir the incoming material, achieving preliminary dry material premixing. Then, the pre-mixed material enters the first mixing tank through the guiding channel to be mixed with water, which can effectively improve the mixing uniformity and mixing rate. The structure is simple and the performance is better. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0034] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0035] See Figures 1 to 4As shown, in order to ensure thorough mixing of materials and avoid the accumulation caused by simultaneous feeding of all materials, which would affect the mixing uniformity and mixing rate, this embodiment provides a high-efficiency mixing device for civil engineering. The device includes a frame 1, within which a first mixing tank 2, a guide channel 7, and a holding trough 5 are fixed sequentially from bottom to top. The holding trough 5 has an opening on its upper side for easy material addition, and a discharge pipe 6 is connected to its lower side. The bottom inner wall of the guide channel 7 is inclined, and the lower end of the guide channel 7 in the inclined direction has an opening. The opening side of the guide channel 7 is connected to the first mixing tank 2 via a conveying pipe 8. The upper wall of the guide channel 7 has an inlet 9, which is directly connected to the discharge pipe 6. Yes, a moving groove 10 is provided on the upper side wall of the material guiding channel 7, located on one side of the inlet 9, and the moving groove 10 penetrates the upper side wall of the material guiding channel 7. A moving block 11 is slidably connected inside the moving groove 10. A baffle 12 is fixedly connected to the lower end of the moving block 11. The baffle 12 is located inside the material guiding channel 7 and slides against the upper side wall of the material guiding channel 7. A linear reciprocating component 13 is provided at the upper end of the moving block 11. The linear reciprocating component 13 is installed on the material guiding channel 7, and the moving end of the linear reciprocating component 13 is connected to the moving block 11. Furthermore, a mixing component 4 is provided inside the first mixing tank 2, and a discharge port 3 is provided on the lower side of the first mixing tank 2. A valve switch is further provided on the discharge port 3 to facilitate the removal of concrete from the first mixing tank 2.

[0036] In the concrete production process, the material is first added to the trough 5. The material enters the guide channel 7 through the drop pipe 6. As the material falls into the guide channel 7, the linear reciprocating component 13 drives the moving block 11 to move the baffle 12 back and forth. This causes the inlet 9 on the guide channel 7 to open and close alternately under the reciprocating motion of the baffle 12, allowing the material to enter the guide channel 7 intermittently. Then, the material is intermittently transported to the first mixing tank through the guide channel 7 for mixing. This ensures that the material that has entered the first mixing tank 2 beforehand can be fully mixed, avoiding the accumulation caused by all the material entering the first mixing tank 2 at the same time. This improves the mixing uniformity between the materials and also increases the mixing rate.

[0037] See Figure 3As shown, furthermore, in order to better realize the reciprocating motion of the baffle 12, the inlet 9 of the guide channel 7 opens and closes alternately and orderly. The linear reciprocating assembly 13 includes a mounting frame 131, and a moving block 11 passes through the moving groove 10 and is fixedly connected to one end of the mounting frame 131 near the inlet 9. Racks 132 are fixedly connected to the two inner side walls of the mounting frame 131 and the moving block 11, which are parallel and opposite to each other in the sliding direction. An incomplete gear 133 is provided between the two racks 132. The incomplete gear 133 is fixedly mounted on the rotating shaft 134. The rotating shaft 134 is connected to the output end of the drive assembly 14, and the drive assembly 14 is fixed on the guide channel 7.

[0038] In use, the drive assembly 14 provides driving force to the rotating shaft 134, causing the rotating shaft 134 to drive the incomplete gear 133 to rotate. During the rotation, the incomplete gear 133 alternately meshes with the two racks 132, causing the mounting frame 131 to slide back and forth along the length of the moving groove 10 on the material guide channel 7. That is, the mounting shell pushes the baffle 12 through the moving block 11 to achieve linear reciprocating motion, so that when the baffle 12 moves forward, it closes the inlet 9 of the material guide channel 7, and when it moves backward, it opens the inlet 9. Thus, under the reciprocating motion of the baffle 12, the inlet 9 of the material guide channel 7 is alternately opened and closed, so that the material in the holding trough 5 enters the material guide channel 7 intermittently.

[0039] See Figure 1 and Figure 2 As shown, furthermore, in order to more effectively improve the mixing effect and mixing efficiency between materials, a second mixing tank 15 is provided between the material guiding channel 7 and the material holding trough 5. The material discharge pipe 6 is inserted into the interior of the second mixing tank 15 from the upper end, and the material discharge pipe 6 is clearance-fitted with the side wall of the second mixing pipe. The lower end of the second mixing tank 15 is connected to an extension pipe 16, which is connected to the material guiding channel 7 through the inlet 9 and is rotatably connected to the side wall of the material guiding channel 7. The upper end of the second mixing tank 15 is connected to the rotating shaft 134 through the transmission assembly 18. The rotating shaft 134 realizes the rotation of the second mixing tank 15 through the cooperation of the transmission assembly 18. A plurality of first stirring rods 17 are evenly distributed on the inner wall of the second mixing tank 15.

[0040] like Figure 6 As shown, the transmission assembly 18 includes a rotating sleeve 181, which is fixedly connected to the upper side of the second mixing barrel 15 and is fitted on the outside of the discharge pipe 6. A first sprocket 182 is fixedly connected to the outer wall of the rotating sleeve 181. The first sprocket 182 is connected to a second sprocket 184 via a chain 183. The second sprocket 184 is fitted and fixed to the upper end of the rotating shaft 134, and the upper end of the rotating shaft 134 is rotatably connected to the frame 1 via a stabilizing plate 19.

[0041] Therefore, during use, the second mixing tank 15 serves as a material transfer channel between the holding trough 5 and the guiding channel 7. The material will enter the second mixing tank 15 in advance. At this time, the drive assembly 14 drives the rotating shaft 134 to rotate, which in turn drives the second sprocket 184 to rotate. The second sprocket 184, through the chain 183 and the first sprocket 182, will drive the second mixing tank 15 to rotate. During the rotation of the second mixing tank 15, the first stirring rod 17 inside can stir the incoming material, realizing the initial dry material premixing. Then, the premixed material enters the first mixing tank 2 through the guiding channel 7 and is mixed with water, which can effectively improve the mixing uniformity and mixing rate. The structure is simple and the use effect is better.

[0042] See Figure 3 and Figure 4 As shown, furthermore, to make the rotation of the second mixing tank 15 more stable, an annular protrusion 25 is fixedly connected to the lower side of the second mixing tank 15, and an arc-shaped guide rail 26 adapted to the annular protrusion 25 is fixedly connected to the upper side of the material guide channel 7. The annular protrusion 25 slides in the arc-shaped guide rail 26, and the lower side of the annular protrusion 25 is higher than the mounting frame 131. In use, the arc-shaped guide rail 26 is set on the side of the inlet 9 away from the moving groove 10, and a part of the annular protrusion 25 will always be placed in the annular guide rail, so that the second mixing tank 15 can be more stable during rotation.

[0043] See Figure 2 and Figure 5 As shown, furthermore, in order to agitate the material in the first mixing tank 2, the agitation assembly 4 includes a hollow rotating rod 41. The rotating rod 41 extends through the upper side wall of the first mixing tank 2 into the interior of the first mixing tank 2, and is rotatably connected to the first mixing tank 2. Multiple second agitating rods 42 are evenly distributed on the side wall of the first mixing tank 2. The upper end of the rotating rod 41 is connected to the output end of the drive assembly 14.

[0044] During use, the drive assembly 14 provides continuous rotational force to the rotating rod 41, so that the rotating rod 41 drives the second stirring rod 42 to continuously stir the material entering the first mixing bucket 2, so that the material can be fully mixed after adding water to form uniform concrete.

[0045] See Figure 2 and Figure 5As shown, furthermore, in order to simultaneously provide driving force to the rotating shaft 134 and the rotating rod 41, so that the baffle 12 can maintain reciprocating motion, the second mixing tank 15 can rotate continuously, and the second stirring rod 42 can move, the drive assembly 14 includes a motor 141. The motor 141 is disposed between the guide channel 7 and the first mixing tank 2, and the motor 141 is fixedly connected to the guide channel 7 and the first mixing tank 2. The output shaft of the motor 141 is fixedly connected to the driving bevel gear 142, which meshes with the first driven bevel gear 143 and the second driven bevel gear 144 respectively. The first driven bevel gear 143 is fitted and fixedly mounted on the rotating rod 41. The rotating shaft 134 passes through the guide channel 7 and is fixedly connected to the second driven bevel gear 144. A stabilizing frame 145 is also fixedly connected between the guide channel 7 and the first mixing tank 2. The stabilizing components are respectively fitted on the rotating shaft 134, the rotating rod 41, and the output shaft of the motor 141 and are rotatably connected to all three. In order to reduce the impact of the material entering the material guide channel 7 on the connection between the rotating shaft 134 and the material guide channel 7, a protective shell is fitted on the outside of the rotating shaft 134. The upper and lower ends of the protective shell are integrally fixed with the side wall of the material guide channel 7. The protective shell is not shown in the figure.

[0046] The motor 141 provides driving force to the active bevel gear 142, enabling the active bevel gear 142 to simultaneously drive the first driven bevel gear 143 and the second driven bevel gear 144 to rotate, thereby achieving synchronous movement of the rotating rod 41 and the rotating shaft 134. This facilitates the simultaneous application of the baffle 12, the second mixing tank 15, and the second stirring rod 42, improving production efficiency. Furthermore, the stabilizer 145 further ensures the stability of the rotating shaft 134 and the rotating rod 41 during rotation.

[0047] See Figure 2 As shown, further, in order to improve the mixing uniformity of the materials in the first mixing tank 2, the lower end of the rotating shaft 134 is inserted into the rotating rod 41 and extends into the first mixing tank 2, and the lower end of the rotating shaft 134 passes through the rotating rod 41. The rotating shaft 134 is fixedly connected to the side wall of the lower end of the rotating rod 41.

[0048] Therefore, during use, the rotating shaft 134 drives the third stirring rod 20 to rotate, and the rotating rod 41 drives the second stirring rod 42 to rotate. Since the rotating shaft 134 and the rotating rod 41 rotate in opposite directions, the second stirring and the third stirring form a synchronous and opposite stirring mode in the first stirring drum, so that the material can be mixed more evenly and the mixing rate is faster under the action of forward and reverse stirring.

[0049] See Figure 1 and Figure 4As shown, furthermore, in order to facilitate the addition of water to the first mixing tank 2 and ensure that the water enters the first mixing tank 2 more evenly, a water tank 21 is also installed on one side of the frame 1. A water pump 22 is fixed on the water tank 21. The water inlet pipe of the water pump 22 is inserted into the water tank 21, and the water outlet pipe of the water pump 22 is connected to an annular pipe 23. The annular pipe 23 is fitted on the side wall of the first mixing tank 2, and multiple water injection pipes 24 are evenly distributed on the annular pipe 23. The end of the water injection pipe 24 away from the annular pipe 23 is inserted into the first mixing tank 2.

[0050] In use, the water tank 21 is filled with water beforehand. Then, during the concrete preparation process, the water pump 22 is started, so that the water pump 22 first pumps the water in the water tank 21 into the annular pipe 23. Then, through multiple water injection pipes 24 evenly arranged on the annular pipe 23, the water can enter the first mixing bucket 2 at multiple locations, thereby making the water addition effect during the material mixing process more uniform and further improving the efficiency of concrete preparation.

[0051] See Figure 1 and Figure 2 As shown, furthermore, in order to more accurately control the amount of various materials added during the production and preparation of concrete, that is, to control the proportion between materials, a storage tank 27 is provided on the upper side of the material trough 5. The storage tank 27 is fixedly connected to the frame 1. The storage tank 27 is provided with multiple material chambers 28, and the lower end of each material chamber 28 is connected to a discharge pipe 29. An electric control switch 30 is provided on the discharge pipe 29. The lower end of each discharge pipe 29 extends into the material trough 5, and a flow detector is provided on each discharge pipe 29. The flow detector is electrically connected to a controller 31, and the controller 31 is also electrically connected to each electric control switch 30. The controller 31 is mounted on the frame 1. The flow detector is not shown in the figure.

[0052] In operation, multiple material chambers 28 can simultaneously store different materials. The controller 31 is then set with numerical ranges for the dosage of various materials. After setting, all control switches and flow detectors are simultaneously activated. During the feeding process from each material chamber 28 into the hopper 5 via the discharge pipe 29, the flow detector monitors the material flow rate in real time. When the material flow rate reaches the preset range, the flow detector transmits a signal to the controller 31. The controller 31 then electrically controls the corresponding electric switch to close, stopping the feeding. This method allows for more precise control of the proportions of various materials during concrete production.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
