Description

Technical Field

[0001] This utility model belongs to the technical field of concrete mixing equipment, and relates to a concrete mixing device for building engineering. Background Technology

[0002] During construction, the quality of concrete mixing plays a crucial role in the stability and durability of the building structure. Existing non-tilting vertical shaft concrete mixers suffer from low mixing efficiency due to the limited number of augers.

[0003] Currently, a Chinese patent with publication number CN220719810U discloses a concrete mixing device, including a mixing drum. The mixing drum is equipped with a mixing mechanism, which includes a motor fixedly installed on the lower surface of the mixing drum. A rotating rod penetrating into the mixing drum is fixedly installed at the output end of the motor. A fixing block is fixedly installed at the end of the rotating rod away from the motor. Three connecting rods are fixedly installed on the side surface of the fixing block. A fixing ring is fixedly installed at the end of the connecting rod away from the fixing block. This concrete mixing device, by providing a fixing ring inside the mixing drum, and four vertical rods on the fixing ring, with mixing blades and mixing rods on the vertical rods, can increase the mixing range of the raw materials in the mixing drum through the cooperation of the mixing blades and mixing rods, thereby greatly improving the mixing efficiency of concrete. This solves the problem of low mixing efficiency caused by the limited number of augers in existing non-tilting vertical shaft mixers. However, in actual use, at least the following shortcomings have been found: Because a large number of mixing blades, mixing rods and other components are located in the mixing space inside the mixing drum, the mixing mechanism is difficult to remove from the mixing drum. After the concrete mixing work is completed, it is difficult for the staff to thoroughly clean the large number of mixing blades, mixing rods and other components on the mixing mechanism as well as the inside of the mixing drum. The cleaning operation is also inconvenient. The residual concrete will not only affect the quality of the next mixing, but also change the subsequent concrete mix ratio, resulting in a decrease in strength and durability, and will also shorten the service life of the equipment.

[0004] Therefore, we propose a concrete mixing and blending device for building engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete mixing device for construction engineering, which aims to solve the problem that after the concrete mixing work is completed, it is difficult for workers to thoroughly clean the numerous mixing blades, mixing rods and other parts of the mixing mechanism as well as the inside of the mixing drum. The cleaning operation is also inconvenient, and the residual concrete will not only affect the quality of the next mixing.

[0006] To solve the above-mentioned technical problems, this utility model provides a concrete mixing device for construction engineering, including a mixing drum. A hydraulic cylinder is provided on the rear side of the mixing drum, and a drive mechanism is provided on the hydraulic cylinder. A concrete mixing mechanism is provided on the drive mechanism. The drive mechanism is used to control the vertical reciprocating motion of the concrete mixing mechanism. The drive mechanism includes an assembly seat, a pad, a motor, a disc, a drive shaft, a rectangular frame, and a U-shaped frame. The assembly seat is fixedly installed on the output shaft end of the hydraulic cylinder. The pad is fixedly installed on the front side wall of the assembly seat. The motor is fixedly installed on the front side wall of the pad. The disc is fixedly installed on the output shaft end of the motor. The drive shaft is fixedly installed on the front side wall of the disc. The rectangular frame is located in front of the disc. The front end of the drive shaft passes through the rectangular frame. The U-shaped frame is fixedly installed at the bottom of the rectangular frame, and the bottom of the U-shaped frame extends into the mixing drum.

[0007] The present invention is further provided that the bottom of the mixing tank is fixedly installed with a plurality of evenly distributed support legs.

[0008] The present invention is further configured such that a support seat is fixedly installed on the rear outer wall of the mixing tank, and a hydraulic cylinder is fixedly installed on the top of the support seat.

[0009] The present invention is further provided that a discharge pipe is fixedly installed at the center of the bottom of the mixing tank, and an electromagnetic discharge valve is fixedly installed on the discharge pipe.

[0010] The present invention is further configured such that the bottom inner wall of the mixing tank has a centrally concave arc-shaped surface structure.

[0011] The present invention is further configured such that the concrete mixing mechanism includes a crossbeam, a second motor, a vertical shaft and multiple mixing rods. The crossbeam is fixedly installed at the bottom of the U-shaped frame, the second motor is fixedly installed at the top of the crossbeam, the vertical shaft is fixedly installed at the output shaft end of the second motor, and the multiple mixing rods are all fixedly installed on the vertical shaft and are evenly distributed.

[0012] The present invention is further configured such that a clearance hole is provided at the top of the crossbeam, and the output shaft end of the second motor passes through the clearance hole.

[0013] The present invention is further configured such that guide rods are fixedly installed on the outer walls of the left and right sides of the rectangular frame, and two guide rails are fixedly installed on the front side wall of the mounting base, with the rear ends of the two guide rods slidably installed on the corresponding guide rails respectively.

[0014] Compared with existing technologies, the concrete mixing device for construction engineering provided by this utility model, through the coordinated action of the drive mechanism and the concrete mixing mechanism, enables the mixing rod to reciprocate in the vertical direction and also make circular motion around the vertical axis. The two movements work together to achieve all-round and multi-angle mixing of the concrete in the mixing drum, ensuring that the various components of the concrete are fully mixed and improving the concrete mixing efficiency. By designing a hydraulic cylinder, the vertical lifting of the drive mechanism and the concrete mixing mechanism can be controlled. After the material is discharged, the vertical axis and multiple mixing rods on the concrete mixing mechanism can be lifted to a suitable position above the mixing drum, which facilitates the workers to thoroughly clean the concrete mixing mechanism and the inside of the mixing drum for the next use.

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a concrete mixing device for construction engineering according to this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0022] See Figures 1-5This utility model provides a concrete mixing device for construction engineering, including a mixing drum 1. A hydraulic cylinder 3 is installed on the rear side of the mixing drum 1, and a drive mechanism 4 is installed on the hydraulic cylinder 3. A concrete mixing mechanism 5 is installed on the drive mechanism 4. The drive mechanism 4 is used to control the vertical reciprocating motion of the concrete mixing mechanism 5. Utilizing the telescopic feature of the hydraulic cylinder 3, the height position of the drive mechanism 4 and the concrete mixing mechanism 5 can be adjusted, thereby enabling the concrete mixing mechanism 5 to be lifted outside the mixing drum 1 to facilitate cleaning of the concrete mixing mechanism 5 and the interior of the mixing drum 1. It should be noted that, as Figures 1-3 As shown, hydraulic cylinder 3 is in the retracted and reset state.

[0023] In this embodiment, the drive mechanism 4 includes an assembly base 41, a support frame 42, a first motor 43, a disc 44, a drive shaft 45, a rectangular frame 46, and a U-shaped frame 47. The assembly base 41 is fixedly installed on the output shaft end of the hydraulic cylinder 3. The support frame 42 is fixedly installed on the front side wall of the assembly base 41. The first motor 43 is fixedly installed on the front side wall of the support frame 42. The disc 44 is fixedly installed on the output shaft end of the first motor 43. The drive shaft 45 is fixedly installed on the front side wall of the disc 44, and the center of the drive shaft 45 does not coincide with the center of the disc 44. The rectangular frame 46 is located in front of the disc 44, and the front end of the drive shaft 45 passes through the rectangular frame 46. The U-shaped frame 47 is fixedly installed at the bottom of the rectangular frame 46, and the bottom of the U-shaped frame 47 extends into the mixing tank 1. The concrete mixing mechanism 5 includes a crossbeam 51, a second motor 52, a vertical shaft 53, and multiple... The mixing rods 54 and the crossbeam 51 are fixedly installed at the bottom of the U-shaped frame 47. The second motor 52 is fixedly installed at the top of the crossbeam 51. The vertical shaft 53 is fixedly installed at the output shaft end of the second motor 52. Multiple mixing rods 54 are fixedly installed on the vertical shaft 53 and are evenly distributed. The first motor 43 drives the disc 44 to rotate, and the drive shaft 45 follows the rotation of the disc 44. The drive shaft 45 drives the rectangular frame 46 and the U-shaped frame 47 to drive the concrete mixing mechanism 5 to perform vertical reciprocating motion. At the same time, the second motor 52 drives the vertical shaft 53 and multiple mixing rods 54 to rotate, thereby realizing the composite motion of multiple mixing rods 54 reciprocating up and down and circumferential mixing. Compared with the traditional single mixing method, it can mix concrete more comprehensively and efficiently, effectively avoid mixing dead corners, ensure that the components of concrete are fully mixed, and significantly improve the uniformity and quality of concrete.

[0024] In this embodiment, a plurality of evenly distributed support legs 2 are fixedly installed at the bottom of the mixing tank 1. The design of the support legs 2 serves to provide stable support for the mixing tank 1.

[0025] In this embodiment, a support seat 6 is fixedly installed on the rear outer wall of the mixing tank 1, and a hydraulic cylinder 3 is fixedly installed on the top of the support seat 6.

[0026] In this embodiment, a discharge pipe 7 is fixedly installed at the center of the bottom of the mixing tank 1, and an electromagnetic discharge valve 8 is fixedly installed on the discharge pipe 7. The design of the discharge pipe 7 and the electromagnetic discharge valve 8 facilitates the discharge of the uniformly mixed concrete out of the mixing tank 1.

[0027] In this embodiment, the bottom inner wall of the mixing drum 1 has a concave arc-shaped structure. The well-mixed concrete can flow smoothly to the discharge pipe 7 under the action of gravity, effectively reducing the residue of concrete at the bottom of the mixing drum 1 and making the discharge more thorough.

[0028] In this embodiment, a clearance hole is provided at the top of the crossbeam 51, and the output shaft end of the second motor 52 passes through the clearance hole to ensure that the second motor 52 rotates smoothly.

[0029] In this embodiment, guide rods 48 are fixedly installed on the outer walls of both the left and right sides of the rectangular frame 46, and two guide rails 49 are fixedly installed on the front side wall of the mounting base 41. The rear ends of the two guide rods 48 are slidably installed on the corresponding guide rails 49. The design of the guide rods 48 and the guide rails 49 provides a stable guiding effect for the rectangular frame 46, ensuring that the rectangular frame 46 can move vertically, avoiding shaking and offset during the movement of the rectangular frame 46, ensuring the stability and reliability of the stirring device, and extending the service life of the equipment.

[0030] In this embodiment, the hydraulic cylinder 3, motor 43, motor 52 and electromagnetic discharge valve 8 can all be purchased on the market. Their wiring connection and control methods are mature technologies in this field and have been fully disclosed, so they will not be described in this article.

[0031] When using the concrete mixing device for construction engineering provided by this utility model, various raw materials for preparing concrete and water in appropriate proportions are poured into the mixing tank 1 in sequence. Then, motor 1 43 and motor 2 52 are started simultaneously. After motor 1 43 starts, its output shaft drives the disc 44 to rotate. The drive shaft 45 on the disc 44 rotates accordingly. Under the guidance of the guide rod 48 and the guide rail 49, the drive shaft 45 drives the rectangular frame 46 to move up and down reciprocally. The U-shaped frame 47 fixed at the bottom of the rectangular frame 46 also moves up and down reciprocally. Simultaneously, the crossbeam 51, motor 52, vertical shaft 53, and multiple stirring rods 54 move up and down reciprocally. After motor 52 is started, its output shaft drives the vertical shaft 53 to rotate, and the stirring rods 54, which are evenly distributed on the vertical shaft 53, also rotate accordingly. In this way, the stirring rods 54 reciprocate in the vertical direction and also make circular motions around the vertical shaft 53. The two motions work together to achieve all-round and multi-angle mixing of the concrete in the mixing bucket 1, ensuring that the components of the concrete are fully mixed and improving the concrete mixing efficiency.

[0032] After the concrete is mixed evenly, turn off motor 1 (43) and motor 2 (52), and open the electromagnetic discharge valve 8 on the discharge pipe 7. Because the bottom of the mixing drum 1 adopts a concave arc surface structure, under the action of gravity, the concrete in the mixing drum 1 naturally converges to the discharge pipe 7 at the bottom center, so that the evenly mixed concrete can be discharged from the mixing drum 1 more comprehensively and smoothly.

[0033] After the material is discharged, the hydraulic cylinder 3 is extended, and the output shaft of the hydraulic cylinder 3 pushes the drive mechanism 4 and the concrete mixing mechanism 5 to rise vertically until the vertical shaft 53 and multiple mixing rods 54 on the concrete mixing mechanism 5 are raised to a suitable position above the mixing drum 1. Then the hydraulic cylinder 3 stops running, which makes it convenient for the staff to thoroughly clean the concrete mixing mechanism 5 and the inside of the mixing drum 1. After cleaning, the hydraulic cylinder 3 is retracted and reset, which pushes the drive mechanism 4 and the concrete mixing mechanism 5 to fall vertically back to their original positions for the next use.

[0034] It should also be noted that all terms such as "set up" and similar descriptive words in this application indicate that two structures have or are connected. However, the specific means by which they are connected are not specified, and are usually conventional connection methods. That is, these methods should be understood as prior art and do not require further explanation. For example, "m is set up with n" simply means that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" simply means that y and x can rotate relative to each other, and whether they are connected by a bearing, y directly passes through x and is rotatably connected to x, or other feasible methods are all within the scope of protection of this application.

[0035] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
