Description

Technical Field

[0001] This invention relates to the technical field of concrete product preparation, and more specifically to a mixing system for automated concrete molding. Background Technology

[0002] Automated concrete molding refers to the process of automating the production of concrete products. It can be broadly divided into steps such as batching, mixing, placement, molding, and curing. Batching involves mixing concrete raw materials in a specific ratio, adding them to a mixing hopper, mixing them, and then pouring the mixture into a placement hopper. The placement hopper then pours the concrete into molds, and finally, molding and curing are carried out. In existing technologies, the various steps and the connections between them primarily rely on manual labor.

[0003] In existing technologies, a mixing device is typically used to mix concrete raw materials. After mixing, the concrete raw materials are poured into a placing hopper, which then moves to distribute the concrete. To achieve automated molding, existing technologies also use mechanical equipment for mixing and distributing. For example, the mixing device uses the one-sided tilting distributing device described in the utility model patent with authorization number CN206551219U, and the distributing device uses the one-sided tilting distributing device described in the utility model patent with authorization number CN212863229U. However, manual addition of materials to the mixing device and manual transfer of the mixed materials to the distributing hopper of the distributing device are still required.

[0004] Because existing technologies require manual addition of concrete raw materials to the mixing equipment and manual transfer of concrete to the placing hopper, the labor intensity for workers is high and the production efficiency is low. Summary of the Invention

[0005] This invention provides an automated concrete mixing system to solve the technical problems of high labor intensity and low production efficiency caused by the need for manual addition of concrete raw materials to the mixing equipment and manual transfer of concrete to the placing hopper in the prior art.

[0006] To solve the above problems, the present invention provides an automated concrete mixing system for molding, comprising:

[0007] track;

[0008] The mixing equipment is slidably mounted on a track. The mixing equipment includes a mixing frame and a mixing bin that is rotatably mounted on the mixing frame about a horizontal axis. The top of the mixing bin has a feeding port. The mixing frame is provided with a turning mechanism for driving the mixing bin to turn over to discharge materials. The mixing equipment also includes a mixing mechanism for mixing concrete raw materials in the mixing bin.

[0009] Storage equipment and lifting equipment are arranged sequentially along the track, and the mixing equipment is used to move back and forth between the storage equipment and the lifting equipment;

[0010] The storage equipment includes multiple storage units arranged sequentially along the track for storing concrete raw materials. Each storage unit has a discharge port located above the track and is used to drop concrete raw materials into the mixing equipment when the mixing equipment moves to a position below the storage unit.

[0011] The lifting equipment includes a lifting frame and a lifting seat that is slidably mounted on the lifting frame in the vertical direction. The mixing equipment is used to move to the lifting seat and be lifted up by the lifting seat to turn over and dump the material.

[0012] The beneficial effects are as follows: When the mixing equipment moves below the storage unit, the storage unit allows concrete raw materials to fall into the mixing chamber of the mixing equipment, where the mixing mechanism then mixes the concrete raw materials. When the mixing equipment moves to the lifting device, the lifting platform of the lifting device raises the mixing equipment to a higher position, and then the tilting mechanism of the mixing equipment tilts the mixing chamber, pouring the concrete into the distribution hopper below. By utilizing the moving material receiving, self-mixing, and high-position tilting material pouring of the mixing equipment, automated material receiving, mixing, and pouring are achieved without manual intervention, reducing labor intensity and improving production efficiency.

[0013] As a further improvement, the track includes a fixed section and a movable section arranged separately, the movable section being fixed on the lifting seat, and the stirring device being moved onto the movable section to be lifted upward by the lifting seat.

[0014] As a further improvement, the lifting seat has an "L" shaped structure. The lifting seat includes a vertical frame and a horizontal frame that are perpendicular to each other. The horizontal frame is located at the lower end of the vertical frame. The lifting frame is equipped with a lifting mechanism connected to the vertical frame. The movable section of the track is fixed on the horizontal frame.

[0015] As a further improvement, the lifting seat is provided with a positioning structure, which is used to position the mixing equipment in the extension direction of the track.

[0016] As a further improvement, the mixer frame is provided with a positioning hole, and the lifting seat is provided with a telescopic top rod. The telescopic direction of the top rod is perpendicular to the extension direction of the track. The top rod is used to fit into the positioning hole and to stop and cooperate with the hole wall of the positioning hole in the extension direction of the track.

[0017] As a further improvement, the track includes a manual filling section located on the side of the storage equipment opposite to the lifting equipment. The mixing equipment can be moved to the manual filling section for manual filling. When the storage equipment malfunctions or a certain type of concrete material is missed, it can be manually added in the manual filling section, in conjunction with automated material receiving.

[0018] As a further improvement, the mixer frame is provided with track wheels supported on the track, and a walking motor is also provided to drive the track wheels to rotate.

[0019] As a further improvement, the tilting mechanism includes a tilting motor and two sprockets. The two sprockets are respectively placed on the mixing chamber and on the tilting motor. A chain is wound between the two sprockets. The rotation axis of the sprocket on the mixing chamber is collinear with the rotation axis of the mixing chamber.

[0020] As a further improvement, the mixing mechanism includes a mixing shaft passing through the mixing chamber and a mixing motor that drives the mixing shaft to rotate. The mixing chamber is supported on the mixing frame by the mixing shaft, and the mixing chamber flips and pours materials around the axis of the mixing shaft.

[0021] As a further improvement, a positioning sleeve is provided at one end of the mixing chamber along the extension direction of the rotation axis of the mixing chamber. The positioning sleeve is eccentrically arranged on the mixing chamber. A retractable positioning shaft is provided on the mixer frame. The extension direction of the positioning shaft is the extension direction of the rotation axis of the mixing chamber. The positioning shaft is used to fit into the positioning sleeve to prevent the mixing chamber from rotating when the mixing mechanism is mixing concrete raw materials. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0041] Example 1 of the automated concrete mixing system provided by the present invention:

[0042] like Figures 1 to 14 As shown, the concrete automated forming mixing system (hereinafter referred to as the mixing system) can automatically receive, feed, mix and pour materials.

[0043] The mixing system mainly consists of four parts: track 100, storage device 200, mixing device 300, and lifting device 400. The function of storage device 200 is to store concrete raw materials; the function of mixing device 300 is to mix and turn over the concrete raw materials; the function of lifting device 400 is to lift mixing device 300 to a certain height, and then mixing device 300 turns over to pour the concrete into the placing hopper below; track 100 connects storage device 200 and lifting device 400, allowing mixing device 300 to move back and forth between storage device 200 and lifting device 400.

[0044] In this embodiment, the track 100 extends in a straight line. For ease of description, the extension direction of the track 100 is defined as the front-to-back direction. The storage device 200 and the lifting device 400 are arranged sequentially along the track, and the storage device 200 is defined as being located in front of the lifting device 400.

[0045] The material storage equipment 200 includes a material storage frame 201, on which multiple solid raw material storage hoppers 202 are arranged sequentially in a front-to-back direction. Each solid raw material storage hopper 202 is used to store concrete raw materials in solid form. Each solid raw material storage hopper 202 stores a different type of concrete raw material; for example, one hopper 202 stores aggregate, and another stores cement. Below each solid raw material storage hopper 202 is a weighing hopper 203, which is used to weigh the falling concrete raw materials and temporarily store the weighed concrete raw materials to a predetermined weight.

[0046] The storage frame 201 spans above the track 100, so that both the solid raw material storage hopper 202 and the weighing hopper 203 are located above the track 100. When the mixing equipment 300 moves to a position below the solid raw material storage hopper 202, the discharge port of the weighing hopper 203 opens, pouring concrete raw materials into the mixing equipment 300. The solid raw material storage hopper 202 and the weighing hopper 203 can adopt existing technologies, such as the automatic quantitative feeding device for granular raw materials with the utility model patent authorized publication number CN210988165U.

[0047] A liquid raw material storage hopper 204 is also installed on the rear side of the storage frame 201. The liquid raw material storage hopper 204 is used to inject liquid raw materials into the mixing equipment 300.

[0048] like Figures 3 to 7As shown, the mixing equipment 300 includes a mixing frame 301 and a mixing chamber 302 rotatably mounted on the mixing frame 301. The mixing chamber 302 has a top feeding port and is enclosed on all sides. Specifically, the mixing frame 301 is a frame structure composed of multiple crisscrossing square steel bars. Two first bearing seats 303 are fixedly installed on the mixing frame 301, and the two first bearing seats 303 are arranged at intervals along the front-back direction. Through holes are provided on both the front and rear sides of the mixing chamber 302, and the through holes on the front and rear sides are arranged coaxially. A mixing shaft 304 is inserted through the through holes of the mixing chamber 302, and both ends of the mixing shaft 304 are inserted into the first bearing seat 303 on the corresponding side. At the same time, second bearing seats 305 are fixedly installed on the exterior of both the front and rear sides of the mixing chamber 302, and the mixing shaft 304 passes through the two second bearing seats 305. That is, the mixing chamber 302 is supported on the mixing shaft 304 by the second bearing seat 305, and is indirectly supported on the first bearing seat 303 by the mixing shaft 304.

[0049] A rotating sprocket 306 is fixed to the outside of one side of the mixing chamber 302 in the front-rear direction. The central axis of the rotating sprocket 306 is collinear with the central axis of the mixing shaft 304. A rotating motor 307 is fixedly installed on the mixer frame 301. A first reducer 308 is connected to the output shaft of the rotating motor 307. A sprocket is also fixed on the output shaft of the first reducer 308. A first chain 319 is wound between the rotating sprocket 306 and the sprocket on the first reducer 308. The rotating motor 307 drives the mixing chamber 302 to rotate around the central axis of the mixing shaft 304, thereby discharging the material.

[0050] A mixing motor 309 is also fixedly installed on the mixer frame 301. A second reducer 310 is connected to the output shaft of the mixing motor 309. The output shaft of the second reducer 310 is connected to the mixing shaft 304. The mixing motor 309 drives the mixing shaft 304 to rotate, thereby mixing the concrete raw materials in the mixing chamber 302.

[0051] Two rows of track wheels 311 are installed at the bottom of the mixer frame 301, allowing the wheels to move on the track. To drive the track wheels 311, a travel motor 312 is also fixedly installed on the mixer frame 301. A third reducer 313 is connected to the output shaft of the travel motor 312. The third reducer 313 has two output shafts, each connected to two track wheels 311 in one row. The travel motor 312 enables the entire mixing equipment 300 to move on the track 100.

[0052] To prevent the mixing chamber from rotating during concrete mixing, such as Figure 5 and Figure 7As shown, a positioning sleeve 314 is fixed to the outside of one side of the mixing chamber 302 in the front-rear direction. The center line of the positioning sleeve 314 is parallel to the rotation axis of the mixing chamber 302 and has a certain distance between them. A first hydraulic cylinder 315 is fixed on the mixer frame 301, and a first positioning shaft 316 is installed on the first hydraulic cylinder 315. The first positioning shaft 316 can fit into the positioning sleeve 314. A support sleeve 317 is also fixed on the mixer frame 301 to support the first positioning shaft 316.

[0053] like Figures 8 to 14 As shown, the lifting device 400 includes a fixed lifting frame 401, on which a lifting seat 402 is slidably mounted vertically. The lifting seat 402 is generally L-shaped and includes a vertical frame 403 and two horizontal supports 404 mounted on the vertical frame 403. The two horizontal supports 404 are connected to the lower end of the vertical frame 403. The horizontal supports 404 extend horizontally and are spaced apart horizontally in the front-back direction. During use, the horizontal supports 404 support the mixing device 300.

[0054] In this embodiment, the lifting frame 401 includes two vertically arranged I-beams 405, which are spaced apart in the front-to-back direction, and the webs 406 of the I-beams 405 extend in the left-to-right direction. Two lugs 407 are fixed to the front and rear ends of the vertical frame 403, respectively. Figure 12 As shown, two lugs 407 at the same end are located on the front and rear sides of the I-beam 405, and a first guide wheel 408 is rotatably mounted between the two lugs 407 at the same end via a first guide wheel mounting shaft 423. The rotation axis of the first guide wheel 408 extends front and rear, and the first guide wheel 408 is attached to the outer surface of the flange 411 of the I-beam 405.

[0055] At the same time, such as Figure 12 As shown, a second guide wheel 410 is rotatably mounted on the upper end of each ear plate 407 via a second guide wheel mounting shaft 409, the axis of which extends front and rear. The second guide wheel 410 is attached to the inner side of the flange 411. Since the inner side of the flange 411 has a certain taper, the second guide wheel 410 is a frustoconical structure to ensure proper contact between the second guide wheel 410 and the inner side of the flange 411. The first guide wheel 408 and the second guide wheel 410 clamp the I-beam 405 in the front-rear direction, thereby positioning the left and right positions of the lifting seat 402. At the same time, the two second guide wheels 410 corresponding to the same I-beam 405 are attached to the inner side of the flange 411 to position the front and rear positions of the lifting seat 402.

[0056] Two positioning plates 412, arranged in a front-to-back arrangement, are fixedly installed on the vertical frame 403. The positioning plates 412 extend vertically. The positioning plates 412 are L-shaped and include a first side 413 and a second side 414. The surface of the first side 413 is perpendicular to the front-to-back direction, and the surface of the second side 414 is perpendicular to the left-to-right direction. The second side 414 is fixed to the vertical frame 403. An elongated hole 415 extending vertically is provided on the first side 413. A positioning rod 416 is fixedly installed on the lifting frame 401. The positioning rod 416 passes through the elongated hole in the front-to-back direction and engages with the left-to-right walls of the elongated hole 415 to limit the left-to-right movement of the lifting seat 402.

[0057] After the mixing device 300 moves onto the cross brace 404, in order to position the mixing device in the front-to-back direction, such as... Figure 5 As shown, two positioning holes 318 are arranged in a front-to-back pattern on the mixer frame 301. Figure 9 As shown, two cylinders 417 are installed on the vertical frame 403, and each cylinder 417 is fixed with a push rod 418, which is used to fit into the positioning hole 318.

[0058] To drive the lifting seat 402 to move up and down, a lifting mechanism is installed on the lifting frame 401. Specifically, the lifting mechanism includes a second hydraulic cylinder 419 mounted on the lifting frame 401. The cylinder body of the second hydraulic cylinder 419 is fixed to the lifting frame 401. A sprocket mounting bracket 420 is fixedly mounted on the piston rod of the second hydraulic cylinder 419. The sprocket mounting bracket 420 includes a vertical shaft and a horizontal shaft fixed on the vertical shaft, with the horizontal shaft extending forward and backward. Lifting sprockets 421 are rotatably mounted at both ends of the horizontal shaft. A second chain 422 is wound around the lifting sprockets 421. One end of the second chain 422 is fixed to the vertical frame 403 of the lifting seat 402, and the other end of the second chain 422 is fixed to the lifting frame 401. When the second hydraulic cylinder 419 extends or retracts, it can drive the lifting seat 402 to move up and down via the second chain 422.

[0059] In this embodiment, as Figure 2 As shown, a material cart 500 is also arranged on one side of the lifting device 400. When there is residual material in the mixing bin 302, the residual material in the mixing bin 302 is poured into the material cart 500 by the rotation of the tilting motor 307.

[0060] like Figure 1 , Figure 2 and Figure 8As shown, the track 100 extends rearward into the lifting device 400. Specifically, the track 100 includes two guide rails, which are arranged at intervals in the left-right direction. The two guide rails are defined as the first guide rail 101 and the second guide rail 102. The first guide rail 101 includes a first guide rail first section 103, a first guide rail second section 104, and a first guide rail third section 105 arranged sequentially from front to back. The first guide rail first section 103, the first guide rail second section 104, and the first guide rail third section 105 are independent of each other. Among them, the first guide rail first section 103 and the first guide rail second section 104 are fixed in position during use. The first guide rail second section 104 is fixed on the lifting frame 401, and the first guide rail third section 105 is fixed on the cross brace 404 of the lifting seat 402. The first guide rail third section 105 can be lifted and lowered by the lifting seat 402.

[0061] The second guide rail 102 includes a first section 106, a second section 107, a third section 108, a fourth section 109, and a fifth section 110 arranged sequentially from front to back. These sections are independent of each other. The first, second, and fourth sections 106, 107, 108, 109, and 110 are fixed in position during use and are fixed to the lifting frame 401. The third section 108 is fixed to the front cross brace 404, and the fifth section 110 is fixed to the rear cross brace 404. Both sections can be raised and lowered by the lifting seat 402.

[0062] Among them, such as Figure 1 and Figure 2 As shown, the front end of the track 100 is located in front of the storage device 200, and the mixing device 300 can move to the front of the storage device 200. The section of the track 100 located in front of the storage device 200 is the manual filling section 111. When the storage device 200 malfunctions, the mixing device 300 moves to the manual filling section 111 to manually add materials.

[0063] In use, the mixing device 300 receives materials sequentially from front to back through the bottom of each solid raw material storage hopper 202 and liquid raw material storage hopper 204. After receiving the materials, it is mixed. After mixing, it moves to the lifting seat 402 of the lifting device 400. The lifting seat 402 lifts the mixing device 300 to a higher position, and then the mixing chamber 302 tilts to discharge the materials. Subsequently, the mixing device 300 descends with the lifting seat 402 to receive materials and mix again.

[0064] In this embodiment, the tilting motor 307, the first reducer 308, the sprocket mounted on the tilting motor, the tilting sprocket 306, and the first chain 319 together constitute a tilting mechanism capable of driving the mixing chamber 302 to tilt. The mixing motor 309, the second reducer 310, and the mixing shaft 304 together constitute a mixing mechanism capable of mixing concrete raw materials.

[0065] In this embodiment, the fixed portion of the track 100 during use constitutes a fixed section, while the portion fixed to the lifting seat 402 is a movable section. Dividing the track 100 into a fixed section and a movable section ensures that the movable section can support the mixing device 300 as the lifting seat 402 rises, and also ensures that the movable section and the fixed section form a complete track after the lifting seat 402 descends, allowing the mixing device 300 to move on the track. The two cross braces 404 together constitute the transverse frame of the lifting seat 402.

[0066] In this embodiment, the solid raw material storage hopper 202 and the weighing hopper 203 below together form a storage unit, and the liquid raw material storage hopper 204 constitutes a storage unit. In other embodiments, the type of storage unit can be changed. For example, the storage unit for storing solid raw materials can only include a storage hopper, which stores the raw materials required for a single fabric application.

[0067] In this embodiment, the top rod 418 on the lifting seat 402 constitutes a positioning structure for positioning the stirring device 300.

[0069] The difference between this and Example 1 is that in Example 1, the mixing shaft serves both as a structure for mixing concrete raw materials and as a support for the mixing chamber.

[0070] In this embodiment, the mixing mechanism includes a mixing motor and mixing blades mounted on the mixing motor. The mixing blades extend into the mixing chamber from the feeding port of the mixing chamber to mix the concrete raw materials.

[0071] Example 3 of the automated concrete mixing system provided by the present invention:

[0072] The difference between this and Example 1 is that in Example 1, the flipping mechanism uses a chain drive mechanism.

[0073] In this embodiment, the flipping mechanism includes a connecting rod eccentrically arranged at one end of the mixing chamber. The connecting rod is driven to rotate by a hydraulic cylinder or a pneumatic cylinder, thereby flipping the mixing chamber.

[0074] Example 4 of the automated concrete mixing system provided by the present invention:

[0075] The difference between this and Example 1 is that in Example 1, the mixer frame has a built-in walking motor, which drives the track wheels to rotate.

[0076] In this embodiment, two sprockets are installed on the track, and a chain is wound between the two sprockets. The chain is connected to the mixer frame, and a motor drives one of the sprockets to rotate, thereby driving the mixer frame to move back and forth.

[0077] Example 5 of the automated concrete mixing system provided by the present invention:

[0078] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the positioning structure is a top rod set on the lifting seat, and correspondingly, the mixer frame is provided with positioning holes.

[0079] In this embodiment, the positioning structure includes a fixed baffle fixed on the lifting seat and a movable baffle that is telescopically mounted on the lifting seat in the left and right direction. After the stirring device moves into place, it presses against the fixed baffle, and the movable baffle extends out together with the fixed baffle to position the stirring device.

[0080] Example 5 of the automated concrete mixing system provided by the present invention:

[0081] The difference between this and Embodiment 1 is that in Embodiment 1, the track includes a fixed section and a movable section, with the movable section fixed on the lifting seat.

[0082] In this embodiment, all tracks are fixed sections, meaning the tracks are fixed to the lifting frame for raising the mixing equipment. The lifting seat includes insert arms extending in the front-to-back direction. Correspondingly, the mixing frame is provided with insertion holes. When the mixing equipment moves into position, the insert arms enter the insertion holes, and then the mixing equipment rises with the lifting seat.

[0083] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
