Description

Technical Field

[0001] This utility model relates to the field of concrete transportation technology, and more specifically, to a segregation-preventing and stabilizing structure for commercial concrete transport tank trucks. Background Technology

[0002] During the transportation of ready-mixed concrete, some of the pre-mixed concrete mortar may segregate, affecting the subsequent use of the concrete mortar.

[0003] A search revealed that Chinese Patent Publication No. CN223001524U discloses "a rail-guided concrete transport tanker, relating to the field of concrete transport technology. This rail-guided concrete transport tanker includes a rail-guided platform, an auxiliary mechanism, and a lifting mechanism. A concrete transport tank is mounted on the top of the rail-guided platform. One end of the concrete transport tank is closed, and the other end is a flared opening with a gradually decreasing diameter. The auxiliary mechanism is mounted on the rail-guided platform and the concrete transport tank, and includes a drive assembly, a rotating support assembly, and a frame. The frame is mounted on the rail-guided platform, and the rotating assembly is mounted on the outer wall of the concrete transport tank. The lifting mechanism is mounted on the rail-guided platform and the frame, and includes a hydraulic cylinder, a lower support frame, and an upper support frame. This rail-guided concrete transport tanker can drive the concrete transport tank to rotate in a relatively stable state, ensuring that the concrete inside is fully mixed and homogeneous, preventing concrete segregation, and guaranteeing concrete performance." However, the following defects still exist: (1) During the rotation of the tank, the concrete mainly makes a circular motion as a whole inside the tank. The relative motion between the concrete is not intense enough, and it cannot be fully mixed, which leads to the concrete segregation problem not being effectively solved.

[0004] (2) Existing concrete transport tanks have smooth inner walls and rely solely on rotating the tank to prevent concrete segregation. Therefore, a segregation-preventing stabilization structure for commercial concrete transport tank trucks is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that, during the rotation of the concrete tank, the concrete mainly undergoes an overall circular motion within the tank, resulting in insufficient relative movement between concrete particles and inability to achieve thorough mixing. This invention provides a stabilizing structure to prevent segregation in commercial concrete transport tank trucks, thereby resolving the issues raised in the background section.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a segregation-preventing and stabilizing structure for a commercial concrete transport tanker, comprising a tank body, wherein a stirring assembly for reverse stirring is provided inside the tank body, and a rotating assembly for rotating the tank body is provided on one side of the tank body. The stirring assembly includes a vehicle body located below the tank. A base is fixedly installed on the top of the vehicle body. A first servo motor is fixedly installed on one side of the base. A rotating shaft is installed at the output end of the first servo motor through a coupling. The rotating shaft passes through the base and is connected to the base bearing. A first spiral blade is fixedly installed on the rotating shaft. The first spiral blade is located inside the tank.

[0007] As a preferred technical solution of this utility model, the rotating component includes a second servo motor fixedly installed on one side of the base. A large gear is installed at the output end of the second servo motor, and a small gear meshes with the large gear. The small gear is sleeved on the outside of the tank and fixedly connected to the tank. The tank is connected to the base bearing.

[0008] As a preferred technical solution of this utility model, a second spiral blade is welded to the inner wall of the tank, and the first spiral blade and the second spiral blade are at a certain distance.

[0009] As a preferred technical solution of this utility model, guide wheels are symmetrically installed on the top of the vehicle body, and slide rails are fixedly provided on the side wall of the tank body, with the guide wheels in contact with the slide rails.

[0010] As a preferred technical solution of this utility model, ladders are symmetrically bolted to the top of the vehicle body, a discharge hopper is bolted to one side of the ladder, a feed hopper is bolted above the discharge hopper, and a guide plate is bolted to one side of the frame, with the guide plate located below the discharge hopper.

[0011] As a preferred embodiment of this utility model, the feeding hopper extends into the interior of the tank, and a frame is fixedly connected to the inner wall of the feeding hopper. The frame is connected to the bearing at the other end of the rotating shaft.

[0012] As a preferred embodiment of this invention, the discharge hopper is located on one side of the guide wheel, and the tank is inclined.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. With the set mixing components, when in use, the rotating shaft starts to rotate under the drive of the first servo motor, and the first spiral blade fixedly installed on the rotating shaft also rotates synchronously. The special spiral shape of the first spiral blade enables it to generate a specific force on the concrete in the tank during rotation, so that the aggregate, cement paste and other components in the concrete are redistributed and mixed, thereby achieving a more uniform mixing effect and effectively preventing the segregation of concrete during transportation. 2. Through the set rotating component, during use, the second servo motor drives the large gear to rotate, and the rotation of the large gear drives the small gear to rotate. At the same time, the tank body and the base are connected by bearings, which provide rotational support for the tank body, allowing the tank body to rotate smoothly and stably around its own axis under the drive of the small gear. Moreover, the rotation direction of the second servo motor and the first servo motor is always opposite. The rotation of the tank body causes the concrete to produce a circular motion as a whole, while the reverse stirring of the first spiral blade penetrates deep into the concrete, generating longitudinal and transverse shear forces, which makes the aggregate, cement paste, additives, etc. fully mixed, greatly improving the uniformity of the concrete and effectively avoiding the differences in concrete performance caused by insufficient mixing, such as uneven strength and segregation.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figure 1 As shown, this embodiment proposes a segregation-preventing stabilization structure for commercial concrete transport tank trucks, including a tank body 1, a stirring assembly 2 for reverse stirring is provided inside the tank body 1, and a rotating assembly 3 for rotating the tank body 1 is provided on one side of the tank body 1. like Figure 2 and Figure 4 As shown, the mixing assembly 2 includes a vehicle body 201 located below the tank body 1. A base 202 is fixedly mounted on the top of the vehicle body 201. A first servo motor 203 is fixedly mounted on one side of the base 202. A rotating shaft 204 is mounted on the output end of the first servo motor 203 via a coupling. The rotating shaft 204 passes through the base 202 and is connected to the bearing of the base 202. A first spiral blade 205 is fixedly mounted on the rotating shaft 204, and the first spiral blade 205 is located inside the tank body 1. In use, the rotating shaft 204 starts to rotate under the drive of the first servo motor 203, and the first spiral blade 205 fixedly mounted on the rotating shaft 204 also rotates synchronously. The special spiral shape of the first spiral blade 205 enables it to exert a specific force on the concrete inside the tank body 1 during rotation, causing the aggregates, cement paste, and other components in the concrete to be redistributed and mixed, thereby achieving a more uniform mixing effect and effectively preventing segregation of the concrete during transportation.

[0021] like Figure 2 and Figure 5As shown, the rotating assembly 3 includes a second servo motor 301 fixedly installed on one side of the base 202. A large gear 302 is installed at the output end of the second servo motor 301. The large gear 302 meshes with a small gear 303. The small gear 303 is sleeved on the outside of the tank body 1 and fixedly connected to the tank body 1. The tank body 1 is connected to the base 202 by a bearing. In use, the second servo motor 301 drives the large gear 302 to rotate, and the rotation of the large gear 302 drives the small gear 303 to rotate. At the same time, the tank body 1 and the base 202 are connected by bearings, which provide rotational support for the tank body 1, allowing the tank body 1 to rotate smoothly and stably around its own axis under the drive of the small gear 303. The rotation directions of the second servo motor 301 and the first servo motor 203 are always opposite. The rotation of the tank body 1 causes the concrete to move in a circular motion, while the reverse stirring of the first spiral blade 205 penetrates deep into the concrete, generating longitudinal and transverse shear forces, which fully mixes the aggregate, cement paste, additives, etc., greatly improving the uniformity of the concrete and effectively avoiding the differences in concrete performance caused by insufficient mixing, such as uneven strength and segregation.

[0022] like Figure 4 As shown, a second spiral blade 4 is welded to the inner wall of the tank 1, and the first spiral blade 205 and the second spiral blade 4 are at a certain distance. When the tank 1 rotates around its own axis, the second spiral blade 4 welded to the inner wall of the tank 1 will move along with it. Under the action of the second spiral blade 4, the concrete will form a spiral flow trajectory inside the tank 1, causing the concrete to move in both the longitudinal and transverse directions, thereby realizing multi-dimensional mixing of the concrete. The first spiral blade 205 and the second spiral blade 4 are at a certain distance, ensuring that they will not interfere with each other during the mixing process, while also forming a complementary mixing force field, so that the concrete in the tank 1 is more comprehensively and fully mixed.

[0023] like Figure 3 As shown, guide wheels 5 are symmetrically installed on the top of the vehicle body 201, and slide rails 6 are fixedly installed on the side wall of the tank body 1. The guide wheels 5 are in contact with the slide rails 6. When the tank body 1 rotates, the slide rails 6 also rotate, and the guide wheels 5 roll along the slide rails 6 to prevent the tank body 1 from shifting or shaking.

[0024] like Figure 3As shown, ladders 7 are symmetrically bolted to the top of the vehicle body 201. A discharge hopper 8 is bolted to one side of the ladders 7, and a feed hopper 9 is bolted above the discharge hopper 8. A guide plate 10 is bolted to one side of the frame 11, located below the discharge hopper 8. The ladders 7 symmetrically bolted to the top of the vehicle body 201 provide a safe and convenient access for workers, facilitating their access to the top of the vehicle body 201 for feeding, discharging, and equipment inspection and maintenance. The guide plate 10, bolted to one side of the frame 11, is located below the discharge hopper 8. When concrete flows out of the discharge hopper 8, the guide plate 10 guides and controls its flow direction and range.

[0025] like Figure 4 As shown, the feed hopper 9 extends into the interior of the tank 1, and a frame 11 is fixedly connected to the inner wall of the feed hopper 9. The frame 11 is connected to the bearing at the other end of the rotating shaft 204. The design of the feed hopper 9 extending into the interior of the tank 1 allows the material to enter the tank 1 directly and accurately. The frame 11 provides a stable support point for the rotating shaft 204, ensuring that the rotating shaft 204 can operate normally and effectively mix the concrete entering the tank 1.

[0026] like Figure 3 and Figure 4 As shown, the discharge hopper 8 is located on one side of the guide wheel 5, and the tank body 1 is inclined. The guide wheels 5 are symmetrically installed on the top of the vehicle body 201 to provide guidance and support for the stable rotation of the tank body 1. The rotation and inclination of the tank body 1 work together to achieve uniform discharge of concrete.

[0027] Specifically, when using the anti-segregation stabilization structure of this commercial concrete transport truck: (e.g.) Figure 2 and Figure 5As shown, the second servo motor 301 drives the large gear 302 to rotate, and the rotation of the large gear 302 drives the small gear 303 to rotate. Simultaneously, the tank body 1 and the base 202 are connected by bearings, which provide rotational support for the tank body 1, allowing it to rotate stably and smoothly around its own axis under the drive of the small gear 303. The rotating shaft 204 begins to rotate under the drive of the first servo motor 203, and the first spiral blade 205, fixedly mounted on the rotating shaft 204, also rotates synchronously. The special spiral shape of the first spiral blade 205 allows it to exert a specific force on the concrete inside the tank body 1 during rotation. Furthermore, the rotation directions of the second servo motor 301 and the first servo motor 203 are always opposite. The rotation of the tank body 1 causes the concrete to undergo circular motion, while the first spiral blade 205... The mixing process penetrates deep into the concrete, generating longitudinal and transverse shear forces to fully mix aggregates, cement paste, additives, etc., greatly improving the uniformity of the concrete and effectively avoiding performance differences caused by insufficient mixing, such as uneven strength and segregation. When the tank 1 rotates around its own axis, the second spiral blade 4 welded to the inner wall of the tank 1 moves along with it. Under the action of the second spiral blade 4, the concrete forms a spiral flow trajectory inside the tank 1, causing the concrete to move in both the longitudinal and transverse directions, thereby achieving multi-dimensional mixing of the concrete. The first spiral blade 205 and the second spiral blade 4 are at a certain distance to ensure that they do not interfere with each other during the mixing process, while also forming a complementary mixing force field, so that the concrete in the tank 1 is more comprehensive and thorough in mixing.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
