Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete energy-saving and emission-reducing aggregate mixing and stirring device. Background Art

[0002] Concrete is a composite material widely used in construction projects. It is mainly composed of cement, aggregate (such as crushed stone or sand), water and, if necessary, admixtures mixed in a certain proportion. Aggregate is an important component of the concrete skeleton. It not only fills the voids in the concrete, but also improves the overall strength and durability of the concrete. Aggregates are usually divided into coarse aggregates and fine aggregates. The former has a larger particle size and is mainly used to provide structural support; the latter has a smaller particle size and is used to fill the voids between coarse aggregates and improve the working performance of concrete. By rationally selecting and proportioning aggregates of different materials, the performance of concrete can be significantly improved to meet various engineering needs.

When in use, the stirring mechanism includes a driving motor device, a stirring shaft, and multiple stirring rods. The new device solves the problem that sand and gravel aggregates at corners cannot be stirred during stirring. However, the existing small-scale stirring equipment has poor stirring effect during stirring, and due to the limited stirring space, stirring holes are prone to occur during the mixing process, and waste is prone to occur when pouring concrete, and there is no effective saving measure.

[0004] Therefore, we provide a concrete energy-saving and emission-reduction aggregate mixing device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a concrete aggregate mixing and stirring device that saves energy and reduces emissions, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a concrete energy-saving and emission-reduction aggregate mixing and stirring device, comprising a support frame and a concrete energy-saving and emission-reduction aggregate mixing and stirring mechanism, wherein the concrete energy-saving and emission-reduction aggregate mixing and stirring mechanism is installed on the upper side of the support frame;

The lifting component is installed on the upper side of the support frame, the mixing and stirring component is arranged on the inner side of the lifting component, and the moving component is arranged on the right side of the lower end of the lifting component.

[0008] Preferably, the lifting assembly includes a concrete aggregate mixing barrel, a connecting piece and a hydraulic rod. The upper slot of the support frame is connected to the concrete aggregate mixing barrel. The top of the concrete aggregate mixing barrel is provided with a connecting piece. The left and right sides of the connecting piece are both connected to the hydraulic rod by slots.

[0009] Preferably, the mixing and stirring assembly includes a driven shaft, an active block, a rotating motor, a multi-end stirring rod and a driven sliding shaft. The left side of the concrete aggregate mixing barrel is equipped with a driven shaft, the outer slot of the driven shaft is connected to the active block, and the rear side of the active block is connected to the rotating motor.

[0010] Preferably, a multi-end stirring rod is provided inside the concrete aggregate mixing barrel, and a driven sliding shaft is installed at the end of the multi-end stirring rod.

[0011] Preferably, the driven sliding shaft and the multi-end stirring rod are connected by a card slot, and the driven sliding shaft and the driven card shaft are at the same horizontal height.

[0012] Preferably, the moving assembly includes a connecting seat, a driven wheel and a moving track. A connecting seat is welded on the right side of the lower end of the concrete aggregate mixing barrel, a driven wheel is installed on the outer side of the connecting seat, and a moving track is provided on the lower side of the driven wheel.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the setting of the concrete energy-saving and emission-reduction aggregate mixing mechanism, when it is necessary to dump the concrete mixture, the driven clamp shaft can transmit the force of the rotating motor through the active clamp block when driving the multi-end mixing rod to rotate. When it is necessary to lift, it is only necessary to set the preset data of the rotating motor so that the active clamp block is always in a vertical state when the rotating motor is paused. In this way, when the concrete aggregate mixing barrel is upward and needs to fall off, it can avoid getting stuck and can be pushed upward by the hydraulic rod. As the hydraulic rod moves upward, the connecting piece will rotate along the hydraulic rod, thereby driving the concrete aggregate mixing barrel to lift, so that the end of the concrete aggregate mixing barrel is tilted upward to generate an arc, which is more conducive to dumping, thereby reducing concrete waste and achieving the effect of energy conservation and emission reduction.

[0016] 2. Through the setting of the concrete energy-saving and emission-reduction aggregate mixing mechanism, when needed, the multi-end mixing rod can improve the mixing effect through internal multi-stirring, avoiding the problem of poor mixing effect due to small mixing space, thereby improving concrete quality, reducing resource waste, and achieving energy conservation and emission reduction effects. The driven sliding shaft can allow the multi-end mixing rod to always remain at the center position of the driven sliding shaft and the driven clamping shaft, preparing for subsequent mixing, and the design of this position can improve the force stability of the multi-end mixing rod during the mixing process. As the hydraulic rod lifts the concrete aggregate mixing barrel, the driven wheel will retract inward along the moving track, thereby avoiding the problem of being unable to lift due to hard bending.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-4 As shown, the utility model provides a technical solution: a concrete energy-saving and emission-reduction aggregate mixing and stirring device, comprising a support frame 1 and a concrete energy-saving and emission-reduction aggregate mixing and stirring mechanism 2, wherein the concrete energy-saving and emission-reduction aggregate mixing and stirring mechanism 2 is installed on the upper side of the support frame 1;

[0025] The concrete energy-saving and emission-reduction aggregate mixing and stirring mechanism 2 includes a lifting component 21, a mixing and stirring component 22 and a moving component 23. The lifting component 21 is installed on the upper side of the support frame 1, the mixing and stirring component 22 is arranged on the inner side of the lifting component 21, and the moving component 23 is arranged on the right side of the lower end of the lifting component 21.

[0026] Furthermore, the lifting assembly 21 includes a concrete aggregate mixing barrel 211, a connecting piece 212 and a hydraulic rod 213. The upper side slot of the support frame 1 is connected to the concrete aggregate mixing barrel 211, and the top of the concrete aggregate mixing barrel 211 is provided with a connecting piece 212. The left and right sides of the connecting piece 212 are both connected to the hydraulic rod 213 by slots. When the concrete mixture needs to be dumped, it can be pushed upward by the hydraulic rod 213. As the hydraulic rod 213 moves upward, the connecting piece 212 will rotate along the hydraulic rod 213, thereby driving the concrete aggregate mixing barrel 211 to lift, so that the end of the concrete aggregate mixing barrel 211 is tilted upward to generate an arc, which is more conducive to dumping, thereby reducing the waste of concrete and achieving the effect of energy saving and emission reduction.

[0027] Furthermore, the mixing and stirring assembly 22 includes a driven clamping shaft 221, an active clamping block 222, a rotating motor 223, a multi-end stirring rod 224 and a driven sliding shaft 225. The driven clamping shaft 221 is installed on the left side of the concrete aggregate mixing barrel 211, and the outer clamping slot of the driven clamping shaft 221 is connected to the active clamping block 222, and the rear side of the active clamping block 222 is connected to the rotating motor 223. When it needs to be used, the driven clamping shaft 221 can transmit the force of the rotating motor 223 through the active clamping block 222 when driving the multi-end stirring rod 224 to rotate. When it needs to be lifted, it is only necessary to set the preset data of the rotating motor 223 so that the active clamping block 222 is always in a vertical state when the rotating motor 223 is paused. In this way, when the concrete aggregate mixing barrel 211 is upward and needs to fall off, it can avoid getting stuck.

[0028] Furthermore, a multi-end stirring rod 224 is provided on the inner side of the concrete aggregate mixing barrel 211, and a driven sliding shaft 225 is installed at the end of the multi-end stirring rod 224. When needed, the multi-end stirring rod 224 can improve the mixing effect through internal multi-stirring, avoiding the problem of poor mixing effect due to small mixing space, thereby improving the quality of concrete, reducing resource waste, and achieving the effect of energy conservation and emission reduction.

[0029] Furthermore, the driven sliding shaft 225 and the multi-end stirring rod 224 are connected by a card slot, and the driven sliding shaft 225 and the driven card shaft 221 are at the same horizontal height. When needed, the driven sliding shaft 225 can allow the multi-end stirring rod 224 to always remain in the center position of the driven sliding shaft 225 and the driven card shaft 221, preparing for subsequent stirring, and this position design can improve the force stability of the multi-end stirring rod 224 during the stirring process.

[0030] Furthermore, the moving assembly 23 includes a connecting seat 231, a driven wheel 232 and a moving track 233. The connecting seat 231 is welded to the right side of the lower end of the concrete aggregate mixing barrel 211, and the driven wheel 232 is installed on the outer side of the connecting seat 231. The lower side of the driven wheel 232 is provided with a moving track 233. When it is needed, as the hydraulic rod 213 lifts the concrete aggregate mixing barrel 211, the driven wheel 232 will retract inward along the moving track 233, thereby avoiding the problem of being unable to lift due to hard bending.

[0031] Example 2

[0032] See also Figure 1 and Figure 3 As shown, in contrast to Example 1, as another embodiment of the present invention, a discharge assembly 3 is installed on the right side of the concrete aggregate mixing barrel 211. The discharge assembly 3 includes a discharge chute 31 and a sealing plate 32. The discharge chute 31 is welded on the right side of the concrete aggregate mixing barrel 211. The inner slot of the discharge chute 31 is connected with the sealing plate 32. When it needs to be used, the sealing plate 32 can prevent leakage during the mixing process. When discharge is required, the sealing plate 32 only needs to be pulled out from the discharge chute 31.

[0033] Working principle: A concrete energy-saving and emission-reducing aggregate mixing device is moved to the working position. When in use, the first step is to move the support frame 1 to the position where it needs to be used, and then pour the concrete and aggregate into the concrete aggregate mixing barrel 211. As the rotating motor 223 drives the active clamping block 222 to rotate through the driven clamping shaft 221, the active clamping block 222 drives the multi-end stirring rod 224 to rotate, and the driven sliding shaft 225 provides support for it, so as to achieve the stirring effect. In the second step, after the concrete mixing is completed, the rotating motor 223 stops the active clamping block 222 in a vertical state. At this time, the hydraulic rod 213 pushes the connecting piece 212 to lift the concrete aggregate mixing barrel 211. At the same time, the driven wheel 232 outside the connecting seat 231 retracts inward along the moving track 233, so that the concrete aggregate mixing barrel 211 presents a certain angle. Finally, the sealing plate 32 is pulled out from the discharge chute 31 to discharge the concrete mixture. In this way, the use process of a concrete energy-saving and emission-reducing aggregate mixing device is completed.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
