[0003] At present, there are two main types of common concrete conveying equipment, one is a mixing tank transport truck with a mixing function, and the other is a dump truck without a mixing function; For large-graded low-slump concrete with a slump of less than 80mm, the concrete has very poor fluidity. If a mixing tank truck is used for delivery, the concrete cannot meet the fluidity requirements required for unloading by the mixing tank truck, which will cause the mixing tank truck to be unable to unload, and the concrete will solidify in the tank, causing the tank to be scrapped; Although dump trucks can solve the problem of unloading large-graded low-slump concrete, dump trucks mainly rely on the weight of concrete to complete unloading, that is, the concrete on the dump truck will fall together when the dump truck's bucket tilts, and it is impossible to achieve continuous and uniform feeding, and it is impossible to accurately control the amount of unloaded concrete, which is difficult to meet the uniform feeding requirements. It can only be evenly delivered to the pouring point through other transfer equipment or manual transportation, resulting in reduced transportation efficiency and increased costs. Therefore, inventing a transportation device that can realize the transportation of large-graded low-slump concrete and continuously and evenly deliver it to the pouring point is a technical problem that needs to be solved by those skilled in the art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Embodiment 1: like Figures 1 to 5 As shown: A low-slump concrete transport tank, comprising a tank body 1 and a spiral discharging device 5, see Figure 2 ;in, The tank body 1 is provided with a loading port 131 and a discharging port 132, and the loading port 131 and the discharging port 132 are arranged near the two ends of the tank body 1 respectively; The spiral discharging device 5 is located outside the tank body 1 , and the spiral discharging device 5 is arranged at the discharge port 132 .

[0029] When loading, the staff can load the large-graded low-slump concrete into the tank body 1 through the loading port 131; In this embodiment, the tank body 1 is arranged on a dump truck, and the state of the tank body 1 can be adjusted by the dump truck, that is, the tank body 1 can be adjusted to a non-unloading state or a unloading state. Specifically, the tank body 1 is lifted by a lifting device 72 on the dump truck, so that one end of the tank body 1 is raised, and the tank body 1 is changed from the non-unloading state to the unloading state; After the concrete is transported to the construction site, the staff can adjust the state of the tank body 1 by controlling the action of the lifting device 72 on the dump truck, that is, adjust the tank body 1 to the unloading state, so that the concrete in the tank body 1 flows to the unloading port 132, and is evenly and continuously discharged to the upper hopper or pouring point in a quantitative manner after passing through the spiral discharging device 5, thereby meeting the requirement of uniform feeding.

[0030] It should be noted that the above-mentioned large-graded low-slump concrete refers to three-graded or four-graded concrete, in which: The range of sand and gravel particle size for three-grade concrete is 5-20mm, 20-40mm and 40-80mm, with a maximum particle size of 80mm. The range of sand and gravel particle size for four-grade concrete is 5-20mm, 20-40mm, 40-80mm and 80-120mm, with a maximum particle size of 120mm. These two types of concrete are suitable for heavy-load concrete, breakwaters, docks and other projects, as well as marine projects, nuclear power plants, etc., which require extremely high strength and durability.

[0031] Optimally, the above-mentioned spiral discharging device 5 includes a rotating drum 51 and a spiral blade 52, see Figure 5 ;in, The spiral blade 52 is spirally arranged on the inner wall of the drum 51, and a gear ring (not shown in the figure) is arranged on the outer wall of the drum 51. One end of the drum 51 is rotatably arranged at the discharge port 132, and the drum 51 is coaxial with the discharge port 132. It also includes a driving device 53, the action end of the driving device 53 is provided with a gear, and the driving device 53 is connected to the rotating drum 51 through the engagement of the gear and the ring gear; in this embodiment, the driving device 53 is arranged on the tank body 1; When unloading, the staff can start the driving device 53, and the driving device 53 drives the rotating drum 51 to rotate, so as to uniformly and continuously transport the concrete in the tank body 1 to the upper hopper.

[0032] In addition, during the unloading process, the spiral discharging device 5 can also make the aggregate in the concrete evenly mixed in the slurry.

[0033] Specifically, the end face of the mouth of the discharge port 132 is provided with an annular embedding groove, which is coaxial with the discharge port 132. One end of the rotating drum 51 is embedded in the embedding groove so that the rotating drum 51 can rotate around the axis of the embedding groove. In order to prevent the rotating drum 51 from separating from the tank body 1, limiting protrusions can also be provided on the outer wall and the inner wall of the rotating drum 51, and limiting grooves are provided at the positions of the embedding grooves corresponding to the limiting protrusions. The movement of the rotating drum 51 along the axial direction of the limiting groove is limited by the cooperation between the limiting protrusion and the limiting groove, so that the connection between the spiral discharging device 5 and the tank body 1 is more stable.

[0034] Optimized, the low-slump concrete transport tank also includes a plurality of first flow control plates 2, which are arranged in the tank body 1 along the length direction of the tank body 1, and the plurality of first flow control plates 2 are arranged in sequence and alternately on the two side walls of the tank body 1 along the vertical direction, and the free side of the first flow control plates 2 extends to the middle of the tank body 1.

[0035] During the unloading process, the concrete in the tank body 1 that falls on the first flow control plate 2 can slide along the first flow control plate 2 toward the unloading port 132 to increase the flow speed of the concrete and improve the unloading efficiency.

[0036] Since large-graded low-slump concrete has poor fluidity, adding the first flow control plate 2 can increase the contact area between the tank body 1 and the concrete, so that the concrete can flow quickly along the first flow control plate 2 to the discharge port 132 to improve the discharge efficiency.

[0037] Optimally, the tank body 1 comprises a material holding portion 11 and a material guiding portion 12, see Figure 1 and Figure 2 ;in, The material receiving portion 11 is a spindle structure, the head of which is arranged as a vertically arranged plane, and the material loading port 131 is arranged at the top of the material receiving portion 11; The material guiding portion 12 is a conical structure, and the discharge port 132 is arranged at the small end of the material guiding portion 12. The tail of the material containing portion 11 is smoothly connected with the large end of the material guiding portion 12, so that when the low-slump concrete transport tank is unloading, the concrete in the material containing portion 11 can flow smoothly and quickly into the material guiding portion 12, and be discharged outward through the discharge port 132 on the material guiding portion 12 to complete the unloading, so as to further improve the unloading efficiency.

[0038] Preferably, the material holding portion 11 and the material guiding portion 12 are integrally formed components to ensure the structural stability of the tank body 1 .

[0039] Optimally, the height of the end of the first flow control plate 2 close to the feed port 131 is greater than the height of the end of the first flow control plate 2 away from the feed port 131; During the feeding process, the concrete falling on the first flow control plate 2 can slide along the first flow control plate 2 toward the tail of the material holding part 11 to quickly fill the tail of the tank body 1, thereby improving the feeding efficiency.

[0040] It should be noted that, due to the poor fluidity of large-grade low-slump concrete, if the first flow control plate 2 is not arranged in an inclined manner, the concrete is easily accumulated below the feeding port 131 and is difficult to flow to the tail of the tank body 1, resulting in reduced feeding efficiency; The first flow control plate 2 is tilted and the height of the end of the first flow control plate 2 close to the loading port 131 is greater than the height of the end of the first flow control plate 2 away from the loading port 131, so that the concrete can slide along the first flow control plate 2 to the tail of the tank body 1, so that the concrete can quickly fill the tail of the tank body 1, thereby improving the loading efficiency.

[0041] It is worth noting that since the material holding portion 11 is a spindle structure, the diameter of the middle portion of the material holding portion 11 is larger than the diameter of the two ends thereof. When concrete flows to the lowest point of the first flow control plate 2, it will slide to the bottom of the material holding portion 11 or the material guiding portion 12, and flow along the material holding portion 11 or the material guiding portion 12 to the middle portion of the material holding portion 11, so as to better fill the space inside the tank body 1.

[0042] Optimally, the low-slump concrete transport tank also includes a partition 3 and a plurality of second flow control plates 4, see Figure 3 and Figure 4 ;in, The partition 3 is vertically arranged in the tank body 1, and the length direction of the tank body 1 is parallel to the plane where the partition 3 is located. The partition 3 can separate the cavity in the tank body 1 into two chambers along the transverse direction of the tank body 1; During transportation, the partition 3 can reduce the lateral movement of the concrete (in the width direction of the tank 1) to reduce the shaking of the concrete, thereby reducing the impact of the inertia generated by the concrete on the transportation tool; Multiple second flow control plates 4 are arranged in the tank body 1 along the length direction of the tank body 1. The multiple second flow control plates 4 are staggered on both sides of the partition 3 from top to bottom, and are staggered with the multiple first flow control plates 2. The free side of the second flow control plate 4 extends to the side wall of the tank body 1, so that an S-shaped material channel is formed between the first flow control plate 2 and the second flow control plate 4. The concrete entering the tank body 1 can flow to the bottom of the tank body 1 through the material channel. The first flow control plate 2 and the second flow control plate 4 can both increase the contact area between the inside of the tank body 1 and the concrete, so that the concrete can flow quickly along the contact surface to the discharge port 132 to improve the discharge efficiency.

[0043] It should be noted that the free side of the first flow control plate 2 refers to the side of the first flow control plate 2 away from the inner wall of the tank body 1 , and the free side of the second flow control plate 4 refers to the side of the second flow control plate 4 away from the partition 3 .

[0044] Optimally, the angle between the first flow control plate 2 and the inner wall of the tank body 1 and the angle between the second flow control plate 4 and the partition 3 are smoothly transitioned through rounded corners to reduce dead angles inside the tank body 1, thereby reducing the occurrence of concrete adhesion and inability to unload.

[0045] Optimally, the free side of the first flow control plate 2 and the free side of the second flow control plate 4 are both inclined downward, see Figure 3 , so that the concrete can flow smoothly to the bottom of the tank body 1 to fill the bottom of the tank body 1.

[0046] Optimally, the low-slump concrete transport tank also includes a vibrating device 6, see Figure 1 , the action end of the vibration device 6 acts on the tank body 1; During the unloading process, the staff can start the vibration device 6 so that the action end of the vibration device 6 can hit the tank body 1, so as to loosen the concrete attached to the inner wall of the tank body 1 and discharge it outward through the discharge port 132, thereby avoiding the situation where the concrete adheres to the inside of the tank body 1 and is difficult to clean.

[0047] Preferably, the vibration device 6 includes an annular bracket, which is sleeved on the outer wall of the tank body 1, and the inner wall of the annular bracket is provided with a plurality of vibration motors, and the plurality of vibration motors are arranged around the circumference of the tank body 1 at equal intervals, and the action end of the vibration motor is arranged toward the tank body 1; When the staff starts the vibration device 6 , the action ends of the multiple vibration motors can hit the outer wall of the tank body 1 to loosen the concrete attached to the inside of the tank body 1 .

[0048] More preferably, there are multiple vibration devices 6, and the multiple vibration devices 6 are arranged along the axial direction of the tank body 1 to improve the vibration effect.

[0049] Optimally, the tank body 1 is provided with a flushing port 14 at one end away from the discharge port 132, see Figures 2 to 4 , the high-pressure water pipe can be plugged into the flushing port 14; When it is necessary to flush the inside of the tank body 1 , the staff can insert a high-pressure water pipe at the flushing port 14 and open the on-off valve on the high-pressure water pipe, and the pressurized water will flush the inside of the tank body 1 to achieve the effect of cleaning the inside of the tank body 1 .

[0050] Embodiment 2: See also Figures 1 to 7 As shown: A transport vehicle, comprising a vehicle body 7 and the low-slump concrete transport tank described in the first embodiment; wherein: The vehicle body 7 is provided with an articulation device 71 and a lifting device 72, wherein the lifting device 72 is provided close to the head of the vehicle body 7, and the articulation device 71 is provided close to the tail of the vehicle body 7; The tank body 1 is arranged on the vehicle body 7, and one end of the tank body 1 provided with the discharge port 132 is arranged toward the rear of the vehicle body 7, and the action ends of the articulated device 71 and the lifting device 72 are both articulated with the tank body; Specifically, the tank body 1 is provided with two sets of hinged seats, which are arranged on the outer wall of the tank body 1 along the length direction of the tank body 1. One hinged seat near the discharge port 132 is hinged to the hinge shaft on the hinge device 71, and one hinged seat near the loading port 131 is hinged to the action end of the lifting device 72. Figure 6 and Figure 7 .

[0051] When the vehicle body 7 transports the tank body 1 filled with concrete to the pouring site, the staff can control the lifting device 72 to extend the action end of the lifting device 72, that is, to lift the end of the tank body 1 provided with the discharge port 131 upward, so that the concrete inside the tank body 1 can slide along the inner wall of the tank body 1 toward the discharge port 132, and be discharged outward evenly and continuously through the discharge port 132, thereby completing the concrete unloading work.

[0052] Preferably, a bracket is also provided on the vehicle body 7, and the bracket is a "U"-shaped structure. When the tank body 1 is placed horizontally on the vehicle body 7, that is, when the tank body 1 is in a non-unloading state, the tank body 1 is stuck in the bracket, and the bracket can play a certain lateral limiting role on the tank body 1 to improve the safety of the transport vehicle. More preferably, there are multiple brackets, and multiple brackets are arranged on the vehicle body 7 along the length direction of the tank body 1 to better fix the tank body 1.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
