[0002] In the construction engineering field, the mixer truck is a key piece of equipment for transporting concrete and other mixed materials. The discharge mechanism of its mixing tank directly affects the efficiency and convenience of material transportation and unloading.

[0003] Currently, existing mixing tank discharge mechanisms are typically fixed at the bottom of the tank, and the position and angle of the discharge port are usually not adjustable, allowing material to be discharged in only one direction. However, in actual construction, due to space constraints and variable pouring locations, fixed discharge ports often lead to inconvenient concrete delivery, requiring frequent vehicle relocation to meet pouring needs at different locations. This not only reduces construction efficiency but also increases operational difficulty and fuel consumption, failing to meet the higher requirements of precise concrete placement in modern construction. A pump truck with mixing and concrete placement functions is proposed. Utility Model Content The purpose of this utility model is to solve the problems of existing mixer truck mixing tank discharge mechanisms having a single discharge direction, inconvenient adjustment, and low applicability, and to propose a mixing tank discharge mechanism that can be adjusted in multiple directions.

[0004] To achieve the above objectives, this utility model employs the following technology: a multi-directional adjustable mixing tank discharge mechanism, comprising a bottom beam, on which a discharge hopper and a conveying pump are mounted. The inlet end of the conveying pump is connected to the outlet of the discharge hopper, and the outlet end of the conveying pump is rotatably connected to a conveying hose via a bearing seat. A connecting hose is fixedly connected to the end of the conveying hose away from the conveying pump, and a discharge pipe is fixedly connected to the end of the connecting hose away from the conveying hose. A rotary drive assembly is mounted on the bottom beam, and a telescopic folding arm assembly is mounted on the rotary drive assembly.

A second motor is fixedly mounted on the other side of the bottom of the fixed plate, and a rotating shaft is fixedly connected to the output end of the second motor. One end of the rotating shaft is connected to one side of the second mounting block through a bearing.

[0006] As a further description of the above technical solution: the angle adjustment mechanism also includes a movable sleeve movably sleeved on the worm gear, the movable sleeve being fixedly connected to the outer wall of the rotating shaft by an installation frame, a rotating rod being rotatably connected to the installation frame via a bearing, the worm gear being fixedly sleeved in the middle of the rotating rod, the rotating rod passing through both ends of the installation frame and being fixedly sleeved with connecting frames, one end of the connecting frame being fixedly connected to a fixed sleeve fixedly sleeved on the discharge pipe.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-3 This embodiment provides a multi-directional adjustable mixing tank discharge mechanism, including a bottom beam 1, a discharge hopper 2 and a conveying pump 3 on the bottom beam 1, the inlet end of the conveying pump 3 is connected to the outlet of the discharge hopper 2, the outlet end of the conveying pump 3 is rotatably connected to a conveying hose 4 through a bearing seat 16, a connecting hose 5 is fixedly connected to the end of the conveying hose 4 away from the conveying pump 3, and a discharge pipe 6 is fixedly connected to the end of the connecting hose 5 away from the conveying hose 4. A rotary drive assembly is provided on the bottom beam 1, the rotary drive assembly includes a mounting box 8 fixed on the bottom beam 1, a rotary motor 9 is provided in the mounting box 8, the output shaft of the rotary motor 9 extends through the mounting box 8 to the top end and is fixedly connected to a turntable 10, a telescopic folding arm assembly is provided on the rotary drive assembly, and an angle adjustment mechanism 7 for precisely adjusting the material distribution direction of the discharge pipe 6 is provided at one end of the telescopic folding arm assembly. The telescopic folding arm assembly includes a first arm 11, a second arm 12, a third arm 13, and a fourth arm 14. The first arm 11 is fixed to the top of the turntable 10, and the bottom of the fourth arm 14 is fixed to the top of the fixed plate 71. The first arm 11 is hinged to the second arm 12, the second arm 12 is hinged to the third arm 13, and the third arm 13 is hinged to the fourth arm 14. The telescopic folding arm assembly also includes a hydraulic cylinder 15. The first arm 11 is connected to the second arm 12, the second arm 12 is connected to the third arm 13, and the third arm 13 is connected to the fourth arm 14 by the extension and retraction of the hydraulic cylinder 15 installed on it, so as to realize the pitching movement of the discharge pipe 6 of the telescopic folding arm assembly. The conveying hose 4 is installed on the telescopic folding arm assembly by a snap fastener.

[0016] Specifically, the bearing housing 16 consists of an outer ring, an inner ring, and balls disposed between the inner and outer rings to ensure that the inner and outer rings can rotate flexibly relative to each other. The discharge end of the conveying pump 3 is fixedly connected to the outer ring of the bearing housing 16 via a flange, and the inlet of the conveying hose 4 is fixedly connected to the inner ring of the bearing housing 16 via a flange. The discharge hopper 2 corresponds to the discharge port of the mixing tank. The bottom beam 1 is installed on the mixer truck. During use, concrete material is discharged from the discharge port at the rear end of the mixing tank and falls into the discharge hopper 2. The positions of the turntable 10 and the telescopic folding arm assembly are initially adjusted according to the pouring position. By starting the rotary motor 9, the rotary motor 9 drives the turntable 10 to rotate, thereby driving the telescopic folding arm assembly. The folding arm assembly and the conveying hose 4 fixed on it rotate together in the horizontal plane, thereby driving the discharge pipe 6 to rotate to the pouring direction. Then, the hydraulic cylinders 15 at the hinge points between the first arm 11, the second arm 12, the third arm 13 and the fourth arm 14 are controlled. By precisely controlling the extension and retraction of these hydraulic cylinders 15, the included angle between each arm section can be changed, thereby realizing the overall unfolding, folding, lifting and lowering of the boom. This allows the outlet of the discharge pipe 6 to move in three-dimensional space, precisely controlling the height and distance of the material, so that the telescopic folding arm assembly extends to the designated position and aligns the material discharge pipe 6 with the pouring point. Subsequently, by starting the first motor 74, the first motor 74 drives the worm gear 76 to rotate. The meshing of the worm gear 76 and the worm wheel 77 drives the rotating rod 79 to rotate. The rotating rod 79 drives the connecting frame 710 to swing left and right, thereby causing the discharge pipe 6 to move in an arc in the left and right direction. By starting the second motor 75, the second motor 75 drives the rotating shaft 712 to rotate, thereby causing the mounting frame 78 to swing back and forth, making the discharge pipe 6 move in an arc in the front and back direction. This allows for precise adjustment of the pitch angle of the discharge pipe 6 outlet, making the adjustment more accurate and facilitating the precise delivery of concrete to the designated pouring position. Then, the conveying pump 3 is started to continuously and stably pump the concrete material into the conveying hose 4, and discharge it through the discharge pipe 6, achieving continuous material delivery and precise pouring to the construction position. This enables flexible and precise positioning of the discharge port of the discharge pipe 6 in three-dimensional space, improving the construction efficiency and quality of material placement. With the help of the installed camera 714, the material discharge situation can be detected, and the pouring situation can be observed intuitively, making it convenient to use.

[0017] Furthermore, the angle adjustment mechanism 7 is characterized by comprising a fixed plate 71, a first mounting block 72 symmetrically fixedly connected to the bottom of the fixed plate 71, and a second mounting block 73 fixedly fixed to the bottom of the fixed plate 71. A first motor 74 is fixedly mounted on one side of the bottom of the fixed plate 71. A worm gear 76 is fixedly connected to the output end of the first motor 74. One end of the worm gear 76 is connected to one side of the second mounting block 73 via a bearing. A worm wheel 77 meshes with the outer wall of the worm gear 76. A second motor 75 is fixedly mounted on the other side of the bottom of the fixed plate 71. A rotating shaft 712 is fixedly connected to the output end of the second motor 75. One end of the rotating shaft 712 is connected to one side of the second mounting block 73 via a bearing. The angle adjustment mechanism 7 also includes a movable sleeve 711 that is movably sleeved on the worm gear 76. The movable sleeve 711 is fixedly connected to the outer wall of the rotating shaft 712 by an installation frame 78. A rotating rod 79 is rotatably connected to the installation frame 78 via a bearing. The worm gear 77 is fixedly sleeved in the middle of the rotating rod 79. The rotating rod 79 passes through both ends of the installation frame 78 and is fixedly sleeved with a connecting frame 710. One end of the connecting frame 710 is fixedly connected to a fixed sleeve 713 that is fixedly sleeved on the discharge pipe 6. A camera 714 is fixedly installed at the bottom of the connecting frame 710.

[0018] Specifically, after initially adjusting the fabric placement position using the turntable 10 and the telescopic folding arm assembly, the first motor 74 is activated. The first motor 74 drives the worm gear 76 to rotate. The meshing of the worm gear 76 and the worm wheel 77 drives the rotating rod 79 to rotate. The rotating rod 79 causes the connecting frame 710 to swing left and right, and the rotating rod 79 causes the fixed sleeve 713 to swing left and right, thereby causing the discharge pipe 6 to move in an arc in the left and right direction. The second motor 75 is then activated, driving the rotating shaft 712 to rotate. The rotating shaft 712 causes the mounting frame 78 to swing back and forth, thus causing the mounting frame 78 to swing back and forth, making the discharge pipe 6 move in an arc in the back and forth direction, facilitating adjustment. The discharge pipe 6 performs omnidirectional motion, thereby precisely adjusting the pitch angle of the outlet of the discharge pipe 6. This allows for more accurate adjustment and facilitates the precise delivery of concrete to the designated pouring position. The operation is convenient, enabling flexible and precise positioning of the discharge port of the discharge pipe 6 in three-dimensional space. In complex construction sites where obstacles are ubiquitous, the discharge port of the discharge pipe 6 can flexibly bypass these obstacles like a human arm through flexible arc movement, finding the optimal delivery path and delivering concrete directly to the final pouring point without secondary transfer. This improves the efficiency and quality of concrete placement. With the installed camera 714, the discharge status can be detected, and the pouring status can be observed intuitively, making it convenient to use.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
