[0052] 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.

[0053] like Figure 1-Figure 13 As shown, a mortar concrete mixing station production line includes a mixing drum 100, a partition assembly 200, and a stirring assembly 300. An annular chamber 110 is provided in the mixing drum 100. The top of the annular chamber 110 passes through the mixing drum 100 upwardly. There are multiple partition assemblies 200. The partition assemblies 200 can rotate around the axis of the annular chamber 110 to drive the mortar concrete slurry to flow from top to bottom. There are also multiple stirring assemblies 300. The stirring assemblies 300 can also rotate around the axis of the annular chamber 110 to drive the mortar concrete slurry to flow from bottom to top. Multiple partition assemblies 200 and multiple stirring assemblies 300 are alternately arranged from top to bottom along the axis of the annular chamber 110. The partition assembly 200 has a first state and a second state. When in the first state, the partition assembly 200 connects the concrete slurry above and below it. When in the second state, the partition assembly 200 isolates the concrete slurry above and below it.

[0054] When in use, the staff first transports the raw aggregates, powders and water for preparing mortar concrete from the top of the annular chamber 110 to the inside of the annular chamber 110, and then starts the partition assembly 200 and the stirring assembly 300, so that the partition assembly 200 and the stirring assembly 300 rotate at the same speed around the axis of the annular chamber 110. During this process, the partition assembly 200 switches back and forth between the first state and the second state. When the partition assembly 200 switches from the second state to the first state, the partition assembly 200 connects the concrete slurry above and below it. At this time, the partition assembly 200 drives the mortar concrete slurry to stir and mix circumferentially while also driving the mortar concrete slurry to flow from top to bottom. The stirring assembly 300 drives the mortar concrete slurry to stir and mix circumferentially while also driving the mortar concrete slurry to flow from bottom to top. Through the joint action of the partition component 200 and the stirring component 300, the mortar concrete slurry inside the annular chamber 110 circulates in the axial direction of the annular chamber 110, thereby increasing the mixing effect of the mortar concrete slurry in the axial direction of the annular chamber 110, and making the mixing uniformity of the mortar concrete slurry better. When the partition component 200 is in the second state, the partition component 200 isolates the concrete slurry above and below it. At this time, the partition component 200 can bear the dead weight of the mortar concrete slurry, reduce the resistance of the partition component 200 during rotation, and avoid transmission failure due to excessive rotation resistance of the partition component 200. At the same time, through the rotation of the partition component 200, the material is mixed in the circumferential direction and moves upward, avoiding the aggregate in the mortar concrete slurry from settling to the lower layer of the slurry.

[0055] It should also be noted that a discharge port 140 is provided at the bottom of the annular chamber 110 . When the mortar concrete slurry inside the annular chamber 110 is evenly mixed, the staff can open the discharge port 140 to discharge the material in the annular chamber 110 out of the annular chamber 110 .

[0056] In a further embodiment, when the partition assembly 200 is in a first state, the stirring assembly 300 rotates around the axis of the annular chamber 110 at a first speed, and when the partition assembly 200 is in a second state, the stirring assembly 300 rotates around the axis of the annular chamber 110 at a second speed, and the first speed is less than the second speed.

[0057] It should also be noted that the partition assembly 200 and the stirring assembly 300 always rotate in the same direction at the same speed.

[0058] When the partition component 200 is in the first state, the rotational resistance of the stirring system formed by the partition component 200 and the stirring component 300 is large. At this time, the stirring component 300 rotates around the axis of the annular chamber 110 at a first speed, mainly to avoid transmission failure of the device caused by excessive rotation speed. When the partition component 200 is in the second state, the rotational resistance of the stirring system formed by the partition component 200 and the stirring component 300 is reduced. At this time, the partition component 200 accelerates to rotate around the axis of the annular chamber 110 at a second speed, in order to enhance the mixing effect of the mortar concrete slurry in the circumferential direction of the annular chamber 110 through the rapid rotation of the stirring component 300.

[0059] In a further embodiment, Figure 3 and Figure 6 As shown, the mortar concrete mixing station production line includes a water injection component 400, which includes a first fixed frame 410 and a center column 420. The first fixed frame 410 is coaxially arranged at the lower part of the annular chamber 110, and the center column 420 is arranged at the center of the upper end of the first fixed frame 410. A plurality of water injection holes 421 are opened on the circumference of the center column 420, and a water inlet (not shown in the figure) is provided on the upper part of the center column 420, and the water inlet is connected to the water injection hole 421.

[0060] When in use, the staff connects the water inlet to the water source switch (such as a faucet) through a conduit, and then turns on the water source. At this time, water enters the center column 420 through the water inlet, and is injected into the annular chamber 110 from the water injection hole 421 to promote the mixing of the mortar concrete slurry.

[0061] In a further embodiment, Figure 7 and Figure 8As shown, the partition assembly 200 includes a rotating ring 210, a fixed ring 220 and a plurality of sector plates 230. The rotating ring 210 can rotate around its axis. The fixed ring 220 is coaxially rotatably arranged on the central column 420. A plurality of first slide grooves 221 are opened in the circumferential direction of the fixed ring 220. The first slide grooves 221 extend along the axial direction of the fixed ring 220. A first connecting rod 240 is provided on one side of the sector plate 230 in its radial direction. A first sliding block 250 is rotatably arranged on the first connecting rod 240. The first sliding block 250 is slidably connected in the first slide groove 221. A first annular tooth groove 241 is opened in the circumferential direction at one end of the first connecting rod 240 away from the sector plate 230. A tooth plate 260 is provided on the inner side of a slide groove 221, and the tooth plate 260 extends along the first slide groove 221. The first annular tooth groove 241 is meshed with the tooth plate 260. A second connecting rod 270 is provided on the other side of the sector plate 230 along its radial direction. The end of the second connecting rod 270 away from the sector plate 230 passes through the rotating ring 210. A first guide ring groove 120 is opened in the circumference of the mixing drum 100. The first guide ring groove 120 includes a first spiral groove portion 121 and a first horizontal groove portion 122. The first spiral groove portion 121 and the first horizontal groove portion 122 are connected. The end of the second connecting rod 270 away from the sector plate 230 is slidably connected in the first guide ring groove 120.

[0062] When in use, the rotating ring 210 rotates around its axis. At this time, the rotating ring 210 drives the fan plate 230 to rotate synchronously through the second connecting rod 270. The fan plate 230 drives the fixed ring 220 to rotate synchronously through the first connecting rod 240 and the first sliding block 250. When the second connecting rod 270 is in the area where the first spiral groove portion 121 is located, under the guiding action of the first spiral groove portion 121 and the second connecting rod 270, the rotating ring 210 rotates circumferentially while moving along the axis of the annular chamber 110. At this time, the rotating ring 210 drives the second connecting rod 270, the fan plate 230 and the first connecting rod 240 to move synchronously along the axis of the annular chamber 110. Under the meshing action of the tooth plate 260 and the first annular tooth groove 241, the fan plate 230 moves along the axis of the annular chamber 110. 0 axis also rotates around its own axis during the movement. This process is the first state of the partition component 200. During this process, the fan-shaped surface of the fan plate 230 is in an inclined state. When the fan plate 230 rotates around its own axis until the fan-shaped surface of the fan plate 230 is horizontal, when the second connecting rod 270 moves to the area where the first horizontal groove portion 122 is located, the partition component 200 switches to the second state. When the second connecting rod 270 moves from the area where the first horizontal groove portion 122 is located to the area where the first spiral groove portion 121 is located again, the partition component 200 switches to the first state. Through the circumferential rotation of the rotating ring 210, the fan-shaped surface of the fan plate 230 switches back and forth between horizontal and inclined, that is, the partition component 200 switches back and forth between the first state and the second state.

[0063] It should be added that if Figure 8 and Fig.10 As shown, in order to enable the two ends of the fan-shaped plate 230 to move synchronously, specifically, a second guide ring groove 423 is opened on the outer peripheral surface of the center column 420, and the second guide ring groove 423 includes a second spiral groove portion 4231 and a second horizontal groove portion 4232, the second spiral groove portion 4231 corresponds to the first spiral groove portion 121, and the second horizontal groove portion 4232 corresponds to the first horizontal groove portion 122, and the first connecting rod 240 is slidably connected in the second guide ring groove 423.

[0064] It should also be noted that the end faces of the first connecting rod 240 away from the fan plate 230 and the end faces of the second connecting rod 270 away from the fan plate 230 are both hemispherical. This is to make the sliding fit between the second connecting rod 270 and the first guide ring groove 120 and the sliding fit between the first connecting rod 240 and the second guide ring groove 423 smoother.

[0065] In a further embodiment, Figure 5 , Fig. 9 and Fig.11As shown, the stirring assembly 300 includes a synchronous ring 310, a center ring 320 and a plurality of stirring plates 330. The synchronous ring 310 and the rotating ring 210 can rotate synchronously and can move relatively. The center ring 320 is coaxially rotatably arranged on the center column 420. The center ring 320 can rotate around its axis. A rotating circle 370 is coaxially fixedly arranged on the upper end of the center ring 320. An elastic telescopic rod 340 is hingedly connected to the circumference of the rotating circle 370. The other end of the elastic telescopic rod 340 is hingedly connected to the stirring plate 330. The center ring 320 and the first sliding block 250 can move along the first The slide groove 221 moves synchronously, the stirring plate 330 is tilted and a second clip 350 is provided on one side of the stirring plate 330 close to the elastic telescopic rod 340, and a first clip 360 is provided on the other side of the stirring plate 330. The tilting direction of the stirring plate 330 is opposite to the tilting direction of the fan-shaped plate 230. The first adjustment arc grooves 311 are evenly spaced in the circumferential direction of the synchronization ring 310. The multiple first adjustment arc grooves 311 are connected end to end in sequence to form a ring. The first adjustment arc grooves 311 include a first clamping arc groove 3111, a first transition arc groove 3112 and a first rotation arc groove 3113. The first clamping arc groove 3111, the first transition arc groove 3112 and the first rotation arc groove 3113 are connected in sequence, the diameter of the first transition arc groove 3112 is larger than the diameter of the first rotation arc groove 3113 and smaller than the diameter of the first clamping arc groove 3111, and second adjustment arc grooves 321 are evenly spaced in the circumferential direction of the center ring 320. The plurality of second adjustment arc grooves 321 are connected end to end in sequence to form a ring, and the second adjustment arc groove 321 includes a second clamping arc groove 3211, a second transition arc groove 3212 and a second rotation arc groove 3213, and the second clamping arc groove 3211, the second transition arc groove 3212 and the second rotation arc groove 3213. The arc groove 3212 and the second rotating arc groove 3213 are connected in sequence, the diameter of the second transition arc groove 3212 is larger than the diameter of the second rotating arc groove 3213 and smaller than the diameter of the second clamping arc groove 3211, the first clamping strip 360 is slidably connected in the first adjustment arc groove 311, the second clamping strip 350 is slidably connected in the second adjustment arc groove 321, the first clamping arc groove 3111 corresponds to the second rotating arc groove 3213, the first transition arc groove 3112 corresponds to the second transition arc groove 3212, and the first rotating arc groove 3113 corresponds to the second clamping arc groove 3211.

[0066] When the partition assembly 200 is in the first state, the first clamping strip 360 is first clamped in the first clamping arc groove 3111. At this time, the second clamping strip 350 is located in the area where the second rotating arc groove 3213 is located. At this time, the rotation of the synchronous ring 310 drives the second clamping strip 350 to rotate, and the second clamping strip 350 drives the stirring plate 330 to rotate. At this time, the stirring plate 330 rotates at a first speed. As the rotating ring 210 moves away from the synchronous ring 310 along its axial direction, the elastic telescopic rod 340 swings toward the center of the center ring 320. At this time, under the transmission action of the elastic telescopic rod 340, the first clamping strip 360 and the second clamping strip 350 move toward the center along the axis of the annular chamber 110, so that the first clamping strip 360 gradually moves from the first clamping arc groove 3111 to the first transition arc groove 3112, and the second clamping strip 350 gradually moves from the second rotating arc groove 3213 to the second transition arc groove 3212. As the rotating ring 210 continues to move away from the synchronous ring 310, the first clamping strip 360 moves from the first transition arc groove 3112 to the first rotating arc groove 3113, and the second clamping strip 350 moves from the second transition arc groove 3212 to the second clamping arc groove 3211. At this time, the stirring plate 330 rotates synchronously with the center ring 320. At this time, the stirring plate 330 rotates at the second speed, and the rotation speed of the stirring plate 330 increases, thereby enhancing the mixing effect of the mortar concrete slurry in the circumferential direction of the annular chamber 110. When the second connecting rod 270 moves from the first horizontal groove part 122 to the inside of the first spiral groove part 121, as the rotating ring 210 continues to rotate, the synchronous ring 310 gradually approaches the rotating ring 210, and the elastic telescopic rod 340 moves in a direction away from the center of the center ring 320. Under the transmission action of the elastic telescopic rod 340, the stirring plate 330, the second clamping strip 350 and the first clamping strip 360 move in a direction away from the center of the center ring 320. When the first clamping strip 360 moves into the first clamping arc groove 3111, the second clamping strip 350 synchronously moves into the second rotating arc groove 3213. At this time, the first clamping strip 360 rotates synchronously with the synchronous ring 310. At this time, the stirring plate 330 rotates at the first speed again. As the rotating ring 210 reciprocates up and down, the stirring plate 330, the second clamping strip 350 and the first clamping strip 360 reciprocate along the radial direction of the center ring 320, so that the rotation speed of the stirring plate 330 switches back and forth between the first speed and the second speed.

[0067] It should be further explained that, in order to enable the synchronizer ring 310 and the rotating ring 210 to rotate synchronously and move relatively, specifically, a linear long groove is provided on the outer circumference of the synchronizer ring 310, and a linear long strip is provided on the inner circumference of the rotating ring 210, and the linear long strip is slidably connected in the linear long groove. In addition, in order to guide and support the synchronizer ring 310, a revolving groove is provided on the inner circumferential wall of the annular chamber 110, and the synchronizer ring 310 is rotatably connected in the revolving groove.

[0068] It should also be noted that the elastic telescopic rod 340 is selected instead of a rigid rod in order to prevent the stirring plate 330 , the second clamping strip 350 and the first clamping strip 360 from getting stuck when moving along the radial direction of the synchronization ring 310 through the elastic expansion and contraction of the elastic telescopic rod 340 .

[0069] In a further embodiment, Figure 4 and Fig.11 As shown, a motor 500 is provided at the bottom of the mixing drum 100, and a transmission shaft 610 is fixedly connected to the output end of the motor 500. The transmission shaft 610 is coaxially rotatably connected in the center column 420 and passes through the upper end of the center column 420. The end of the transmission shaft 610 away from the motor 500 is fixedly connected to a center gear 620. A second fixed frame 630 is coaxially fixedly provided on the upper part of the annular chamber 110, and a first planetary gear 640 is provided on the second fixed frame 630. The first planetary gear 640 is meshed with the center gear 620. The inner circumference of the first annular frame 650 is provided with a gear ring, which is meshed with the first planetary gear 640. The first annular frame 650 and the rotating ring 210 can rotate synchronously.

[0070] When the rotating ring 210 is driven to move around the axis of the annular chamber 110, the motor 500 is started, and the transmission shaft 610 is driven to rotate by the motor 500, and the transmission shaft 610 drives the central gear 620 to rotate, and the central gear 620 drives the first planetary gear 640 to rotate. The first planetary gear 640 drives the first annular frame 650 to rotate through the ring gear, and the first annular frame 650 rotates synchronously with the rotating ring 210, so that the rotating ring 210 rotates at a first speed.

[0071] It should be further explained that, in order to enable the first annular frame 650 to rotate synchronously with the rotating ring 210, specifically, a linear long groove is also opened on the outer circumference of the first annular frame 650, and a linear long strip is opened on the inner circumference of the rotating ring 210, and the linear long strip is slidably connected in the linear long groove. In addition, in order to guide and support the first annular frame 650, a revolving groove is opened on the inner circumferential wall of the annular chamber 110, and the first annular frame 650 is rotatably connected in the revolving groove.

[0072] It should be added that the planetary gear mechanism is selected as the transmission mechanism for driving the partition assembly 200 and the stirring assembly 300 to rotate at the first speed because the planetary gear mechanism is a speed reduction mechanism.

[0073] In a further embodiment, Fig.10As shown, a plurality of through grooves 422 are opened on the circumference of the center column 420, and a second planetary gear 670 is rotatably connected in the through groove 422. A second annular tooth groove is provided on the transmission shaft 610 at a position corresponding to the second planetary gear 670, and the second annular tooth groove is meshed with the second planetary gear 670. A third annular tooth groove is provided on the inner circumferential surface of the center ring 320, and the second planetary gear 670 is meshed with the third annular tooth groove.

[0074] When the transmission shaft 610 rotates, the second planetary gear 670 is driven to rotate through the second annular tooth groove on the transmission shaft 610, and the second planetary gear 670 drives the center ring 320 to rotate through the third annular tooth groove. When the second clamping strip 350 is clamped into the second clamping arc groove 3211, the second clamping strip 350 follows the center ring 320 and rotates synchronously at the first speed.

[0075] In a further embodiment, Figure 1 As shown, a material guide hopper 130 is provided on the top of the mixing drum 100 .

[0076] The guide hopper 130 is provided to guide the mortar concrete slurry to prevent the material from overflowing from the top of the annular chamber 110 .

[0077] In a further embodiment, Figure 1 As shown, the mortar concrete mixing station production line also includes a conveyor 700 , which is used to transport the raw materials for making the mortar concrete slurry into the guide hopper 130 .

[0078] In a further embodiment, when the number of first guide annular grooves 120 in the annular chamber 110 is greater than or equal to two, the pitch of the first spiral groove portion 121 in the first guide annular groove 120 should be increased from bottom to top, so that the partition assembly 200 can generate negative pressure suction in the first working state, so as to accelerate the water in the water injection hole 421 to be sucked out into the annular chamber 110, thereby achieving the effect of automatically and quickly injecting water into the annular chamber 110.

[0079] It should also be noted that the motor 500 used in the present invention adopts an energy-saving electric motor as a power source in order to reduce energy consumption and achieve the purpose of efficient and energy-saving production.

[0080] 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.

[0081] 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. Therefore, the protection scope of the present invention shall be subject to the attached claims.
