Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing equipment, and in particular to a concrete mixing device for prefabricated building production. Background Art

[0002] When mixing concrete, a concrete mixing device is usually used. However, when the aggregate is poured into the mixing device, the aggregate will settle, resulting in the aggregate being accumulated at the bottom of the mixing device. The current mixer generally rotates along the vertical axis, and when mixing the concrete, the aggregate at the bottom cannot be turned upward, resulting in poor concrete mixing effect. Summary of the invention

[0003] Based on this, it is necessary to provide a concrete mixing device for prefabricated building production to address the technical problem that the current concrete mixing device has a poor mixing effect.

[0004] The above purpose is achieved through the following technical solutions: A concrete mixing device for prefabricated building production comprises a tank body, wherein a feeding mechanism is arranged inside the tank body, wherein the feeding mechanism comprises a rotating shaft, wherein the rotating shaft extends in the up-down direction, and a plurality of mixing mechanisms are evenly arranged in the circumference of the rotating shaft, wherein a spiral conveying plate is arranged on the rotating shaft, wherein the spiral conveying plate is spirally wound on the rotating shaft in the up-down direction, and a guard plate extending in the up-down direction is arranged on the edge of the spiral conveying plate, wherein the size of the guard plate in the up-down direction gradually decreases from bottom to top, and the rotation of the rotating shaft enables the spiral conveying plate to convey aggregate at the bottom of the tank body to the top of the tank body, and at the same time enables small aggregate particles to be thrown out from the lower guard plate and large aggregate particles to be thrown out from the upper guard plate, and the mixing mechanism is used to mix the aggregate thrown out by the feeding mechanism.

[0005] Furthermore, the spiral conveying plate is tiltedly arranged on the rotating shaft, and a side of the spiral conveying plate away from the rotating shaft is higher than a side of the spiral conveying plate close to the rotating shaft.

[0006] Furthermore, the spiral conveying plate is vertically arranged on the rotating shaft.

[0007] Furthermore, along the up and down directions, the maximum diameters of the spiral conveying plates are equal.

[0008] Furthermore, the maximum diameter of the spiral conveying plate gradually decreases from bottom to top.

[0009] Furthermore, a feed plate is provided at the bottom of the spiral conveying plate, and the feed plate is arranged horizontally.

[0010] Furthermore, the stirring mechanism includes a first stirring shaft and a second stirring shaft arranged inside the tank body, the first stirring shaft and the second stirring shaft both extend in the up and down directions, the first stirring shaft and the second stirring shaft rotate synchronously in opposite directions, the first stirring shaft is provided with a plurality of first stirring blades distributed in the up and down directions, the second stirring shaft is provided with a plurality of second stirring blades distributed in the up and down directions, the first stirring blades and the second stirring blades are both inclined plates and are the same size.

[0011] Furthermore, the first stirring blade and the second stirring blade are inclined in opposite directions, and the first stirring blade and the second stirring blade are arranged alternately.

[0012] Furthermore, the first stirring shaft is provided with a first gear, the second stirring shaft is provided with a second gear, the first gear is meshed with the second gear, the tank body is provided with a first driving mechanism and a second driving mechanism, the first driving mechanism is used to drive the first stirring shaft to rotate, and the second driving mechanism is used to drive the rotating shaft to rotate.

[0013] Furthermore, a feed port is provided on the top of the tank body, and a discharge port is provided on the bottom of the tank body, and the feed port and the discharge port are staggered in the circumferential direction of the tank body.

[0014] The beneficial effects of the present invention are: In the concrete mixing device for prefabricated building production provided by the present invention, aggregates deposited at the bottom of the tank body are transported upward by the spiral conveyor plate. Since the size of the guard plate in the up-down direction gradually decreases from bottom to top, the gap formed by the lower guard plate and the spiral conveyor plate is small, and the gap formed by the upper guard plate and the spiral conveyor plate is large. In this way, during the transportation process, small-particle aggregates will be first thrown out from the bottom of the tank body under the centrifugal force of the spiral conveyor plate and stirred by the stirring mechanism. The large-particle aggregates will then be thrown out from the top of the tank body under the centrifugal force of the spiral conveyor plate. The large-particle aggregates will be stirred by the stirring mechanism for a longer time during the descent process. Therefore, the large-particle aggregates will fall only after the small-particle aggregates are stirred and mixed evenly to form a suspended state, making it easier for the large-particle aggregates to be evenly mixed with the small-particle aggregates in the suspended state, while preventing the large-particle aggregates from settling to the bottom of the tank body, thereby improving the concrete mixing effect.

[0015] Secondly, the first mixing blade and the second mixing blade cooperate to drive the aggregate to swing from the side close to the rotating shaft toward the inner wall of the tank, so that the aggregate is randomly scattered around, and then the scattered large aggregate particles are mixed with the small aggregate particles, further improving the concrete mixing effect.

[0020] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0021] like Figures 1 to 6 As shown, an embodiment of the present invention provides a concrete mixing device for prefabricated building production, including a tank body 110, the bottom of the tank body 110 is set on the ground through legs 111, the tank body 110 is provided with a feeding mechanism 130 inside, the feeding mechanism 130 includes a rotating shaft 133, the rotating shaft 133 extends in the up-down direction, a plurality of mixing mechanisms 120 are evenly arranged in the circumference of the rotating shaft 133, a spiral conveying plate 131 is provided on the rotating shaft 133, and the spiral conveying plate 131 is spirally conveyed in the up-down direction. The spiral conveying plate 131 is wound around the rotating shaft 133, and the edge of the spiral conveying plate 131 is provided with a guard plate 132 extending in the up-down direction. The size of the guard plate 132 in the up-down direction gradually decreases from bottom to top. The rotation of the rotating shaft 133 enables the spiral conveying plate 131 to transport the aggregate at the bottom of the tank body 110 to the top of the tank body 110, and at the same time, small particles of aggregate are thrown out from the lower guard plate 132, and large particles of aggregate are thrown out from the upper guard plate 132. The stirring mechanism 120 is used to stir the aggregate thrown out by the feeding mechanism 130.

[0022] After such arrangement, the aggregate deposited at the bottom of the tank body 110 is transported upward by the spiral conveying plate 131. Since the size of the guard plate 132 in the up and down direction gradually decreases from bottom to top, the gap formed by the lower guard plate 132 and the spiral conveying plate 131 is small, and the gap formed by the upper guard plate 132 and the spiral conveying plate 131 is large. In this way, during the conveying process, the small-particle aggregate will be thrown out from the bottom of the tank body 110 first under the centrifugal force of the spiral conveying plate 131 and stirred by the stirring mechanism 120. The large-particle aggregate will then be thrown out from the top of the tank body 110 under the centrifugal force of the spiral conveying plate 131. The large-particle aggregate will be stirred by the stirring mechanism 120 for a longer time during the descent process. Therefore, the large-particle aggregate will fall only after the small-particle aggregate is stirred and mixed evenly to form a suspended state, making it easier for the large-particle aggregate to be evenly mixed with the small-particle aggregate in the suspended state, while preventing the large-particle aggregate from settling to the bottom of the tank body 110, thereby improving the concrete mixing effect.

[0023] In one embodiment, the spiral conveying plate 131 is tiltedly disposed on the rotating shaft 133 , and a side of the spiral conveying plate 131 away from the rotating shaft 133 is higher than a side of the spiral conveying plate 131 close to the rotating shaft 133 .

[0024] The spiral conveying plate 131 is tilted so that the larger particles of aggregate on each layer of the spiral conveying plate 131 are closer to the rotating shaft 133 under the action of gravity, so that the smaller particles of aggregate on each layer of the spiral conveying plate 131 can be thrown out through the guard plate 132, thereby promoting the throwing out of the smaller particles of aggregate, accelerating the mixing of small particles of aggregate, and making it easier to form a suspended state under the tank body 110.

[0025] In one embodiment, the spiral conveying plate 131 is vertically arranged on the rotating shaft 133. Such an arrangement has a simple structure and is easy to process.

[0026] In one embodiment, the maximum diameters of the spiral conveying plate 131 are equal in the vertical direction. Thus, the spiral conveying plate 131 is cylindrical as a whole, and the thrown out large aggregate particles and small aggregate particles are evenly distributed in the vertical direction.

[0027] In one embodiment, the maximum diameter of the spiral conveying plate 131 gradually decreases from bottom to top. The spiral conveying plate 131 is tapered as a whole, more small aggregate particles are thrown out from the bottom, and less large aggregate particles are thrown out from the top, thereby increasing the speed at which the bottom of the tank body 110 forms a suspended state.

[0028] In one embodiment, a feed plate 134 is provided at the bottom of the spiral conveying plate 131 , and the feed plate 134 is arranged horizontally. The feed plate 134 is arranged horizontally to facilitate the aggregate at the bottom of the tank body 110 to enter the spiral conveying plate 131 .

[0029] In one embodiment, the stirring mechanism 120 includes a first stirring shaft 121 and a second stirring shaft 125 disposed inside the tank body 110, the first stirring shaft 121 and the second stirring shaft 125 both extend in the up-down direction, the first stirring shaft 121 and the second stirring shaft 125 rotate synchronously in opposite directions, the first stirring shaft 121 is provided with a plurality of first stirring blades 122 distributed in the up-down direction, the second stirring shaft 125 is provided with a plurality of second stirring blades 126 distributed in the up-down direction, the first stirring blades 122 and the second stirring blades 126 are both inclined plates and have the same size. The first stirring blades 122 and the second stirring blades 126 both have a tendency to move aggregates in the up-down direction, thereby promoting the mixing of aggregates in the up-down direction.

[0030] In one embodiment, the first stirring blade 122 and the second stirring blade 126 are inclined in opposite directions, and the first stirring blade 122 and the second stirring blade 126 are arranged alternately. The first stirring blade 122 and the second stirring blade 126 are arranged alternately to avoid interference.

[0031] like Figure 2 As shown, from top to bottom, the first stirring blade 122 is inclined in the clockwise direction from top to bottom, and the second stirring blade 126 is inclined in the counterclockwise direction from top to bottom. When rotating, the first stirring blade 122 rotates in the clockwise direction, and the second stirring blade 126 rotates in the counterclockwise direction. The first stirring blade 122 and the second stirring blade 126 are staggered, so that the first stirring blade 122 and the second stirring blade 126 can drive the aggregate to swing from the side close to the rotating shaft 133 toward the inner wall of the tank body 110, so that the aggregate is randomly scattered around, and then the first stirring blade 122 and the second stirring blade 126 mix the scattered large aggregate particles with the small aggregate particles to improve the mixing effect.

[0032] The first stirring shaft 121 is provided with a first gear 123, the second stirring shaft 125 is provided with a second gear 124, the first gear 123 meshes with the second gear 124, the tank body 110 is provided with a first driving mechanism 116 and a second driving mechanism 117, the first driving mechanism 116 is used to drive the first stirring shaft 121 to rotate, and the second driving mechanism 117 is used to drive the rotating shaft 133 to rotate. The tank body 110 is provided with a cover plate 115, the first driving mechanism 116 is a first motor, the second driving mechanism 117 is a second motor, and the first motor and the second motor are both fixedly arranged on the cover plate 115. A gear bearing plate 118 is arranged inside the tank body 110, and the first gear 123 and the rotating shaft 133 of the second gear 124 are supported and arranged on the gear bearing plate 118.

[0033] A feed port 114 is provided above the tank body 110, and a discharge port 113 is provided below the tank body 110, and the feed port 114 and the discharge port 113 are staggered in the circumferential direction of the tank body 110. In this way, the aggregate is stirred for a longer time inside the tank body 110, and the phenomenon of the aggregate flowing out directly before being stirred evenly is avoided.

[0034] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: The aggregate is poured in from the feed port 114, and then the first driving mechanism 116 and the second driving mechanism 117 are started, so that the first driving mechanism 116 drives the plurality of first stirring shafts 121 to rotate, and then drives the second stirring shaft 125 to rotate. From top to bottom, the first stirring shaft 121 rotates clockwise, and the second stirring shaft 125 rotates counterclockwise; the second driving mechanism 117 drives the rotating shaft 133 to rotate, so that the spiral conveying plate 131 rotates, so that the aggregate deposited at the bottom of the tank body 110 is transported upward by the spiral conveying plate 131. During the transportation process, the small-particle aggregate will be thrown out from the bottom of the tank body 110 under the centrifugal force of the spiral conveying plate 131, and will be stirred by the stirring mechanism 120, and the large-particle aggregate will then be transported on the spiral conveying plate 131. 1 is thrown out from the top of the tank body 110, and the large aggregate particles are stirred by the stirring mechanism 120 for a longer time during the descent process, so that the large aggregate particles will fall only after the small aggregate particles are stirred and mixed evenly to form a suspended state, making it easier for the large aggregate particles to be mixed evenly with the small aggregate particles in the suspended state, while preventing the large aggregate particles from settling to the bottom of the tank body 110, thereby improving the concrete mixing effect; secondly, the first stirring blade 122 and the second stirring blade 126 can cooperate to drive the aggregate to be thrown from the side close to the rotating shaft 133 toward the inner wall of the tank body 110, so that the aggregate particles are randomly scattered around, and then the scattered large aggregate particles are stirred and mixed with the small aggregate particles, thereby further improving the concrete mixing effect.

[0035] Finally, the mixed concrete can be discharged from the discharge port 113.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
