Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering machinery, in particular to a multi-functional excavator feeding mixer truck. Background Technique

[0002] An excavator feeding mixer truck is an engineering vehicle integrating functions such as loading, mixing, excavating, transporting and fixed-point discharging. It combines the flexibility of an excavator and the concrete mixing ability of a mixer truck, and is widely used in construction projects, municipal engineering, highway and bridge construction, precast component factories and other places.

[0003] There are some deficiencies in the design of the existing excavator feeding mixer trucks. One significant problem is that their vehicle frames adopt a split design, which means that each part of the vehicle frame is manufactured separately and then assembled together by bolts or other connection methods. This design method may bring the following problems: First, the structural stability of the split vehicle frame is not high because the connection points may become potential weaknesses. Especially under long-term use and high-load working conditions, these connection points may become loose or damaged. Second, when repairing and replacing the split vehicle frame, it usually requires disassembling multiple connection parts, which may lead to increased repair costs and extended machine downtime. In addition, although split vehicle frames may be more convenient for transportation and handling, they may require more processes and precision control during the manufacturing process, thus increasing the manufacturing cost. Finally, due to the existence of multiple connection points, split vehicle frames may show low durability under some extreme working conditions, such as severe vibration or impact load. The split vehicle frame has low center of gravity stability during loading and turning, is prone to rollover, and has high requirements for the operability of the driver. For this reason, we provide a multi-functional excavator feeding mixer truck with good structural stability, good durability and simple maintenance method. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-functional excavator feeding mixer truck to solve the problems raised in the above background technique.

[0005] The utility model is achieved through the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: Please refer to Figures 1 to 4, according to an embodiment of the present utility model, a technical solution is provided: a multi-functional excavator loading mixer truck, including a vehicle frame 1, an excavating arm 2, a mixer 3 and a cab 4 provided on the vehicle frame 1. The vehicle frame 1 is an integral steel structure. The vehicle frame 1 includes a main frame body 10 with wheels 13 provided at the bottom and arranged along the length direction of the mixer truck, and a first mounting position 11 and a second mounting position 12 provided at the front end of the main frame body 10 and distributed relatively along the width direction of the mixer truck. The mixer 3 is installed at the tail of the main frame body 10, and the excavating arm 2 and the cab 4 are respectively installed at the first mounting position 11 and the second mounting position 12. In this embodiment, a bucket 20 is further provided at the front end of the excavating arm 2, and the bucket 20 can adopt any form of bucket 20 in the prior art. For the mixer truck with the above structure, first of all, due to its continuous structure, the integral vehicle frame 1 can provide better overall strength and stiffness, thereby reducing vibration and deformation during operation and improving the stability of the whole vehicle; secondly, the integral structure reduces the connection points, enabling the vehicle frame 1 to better withstand long-term use and high-load working conditions, reducing manufacturing and maintenance costs. Finally, although the integral vehicle frame 1 may have a higher cost in initial manufacturing, due to its simplified structure and less maintenance requirements, it may reduce the overall maintenance cost in the long run.

[0025] In the design of traditional multi-functional excavator loading mixer trucks, the steering of the excavating arm 2 is usually linked with the cab 4, resulting in problems of limited vision and inconvenient operation for the driver during operation. To solve this problem, in this exemplary embodiment, the cab 4 is fixed relative to the vehicle frame 1, and the excavating arm 2 is rotatable relative to the vehicle frame 1. A rotary motor 5 for driving the excavating arm 2 to rotate relative to the vehicle frame 1 is provided on the vehicle frame 1. Specifically, in this improved design, the excavating arm 2 is driven by a rotary motor 5, and the motor is equipped with a high-precision servo control system, which can accurately control the rotation angle and speed of the excavating arm 2. Such a configuration enables the excavating arm 2 to rotate freely within a wide range without the need to adjust the direction of the entire vehicle, thus greatly improving the efficiency and accuracy of material handling; in addition, since the cab 4 does not need to bear additional torsion with the movement of the excavating arm 2, this not only helps to protect the structure of the mixer truck and extend its service life, but also plays a positive role in improving work efficiency.

[0026] In this exemplary embodiment, the mixer 3 includes a tank body 30 and a stirring structure. The tank body 30 has an open upper end and is fixed to the vehicle frame 1. The stirring structure includes a main shaft 31 driven to rotate by a hydraulic motor 34, stirring arms 32 fixed to the main shaft 31, and stirring blades 33 provided at the free ends of the stirring arms 32. During the operation of the multi-functional excavator loading mixer truck, after the excavating arm 2 precisely feeds the material into the tank body 30, the hydraulic motor 34 is started. With the stable operation of the hydraulic motor 34, the main shaft 31 begins to rotate, driving the stirring arms 32 fixed to the main shaft 31 to rotate together. The stirring blades 33 are usually designed with specific angles and shapes so as to generate flow vortices during rotation, pushing the material in the tank body 30 to perform an efficient circulating motion, increasing the contact area with the material, and ensuring that every particle of the material can be evenly stirred. In addition, the rotational speed of the hydraulic motor 34 can be adjusted according to actual needs to adapt to different material characteristics and mixing requirements, thereby achieving the optimization of energy conservation and efficiency. By precisely controlling the stirring speed and time, the operator can accurately complete the entire stirring process from raw materials to finished products, meeting the requirements under different construction conditions. In short, the efficient drive of the hydraulic motor 34 and the organic cooperation of the main shaft 31, stirring arms 32, and stirring blades 33 together constitute the key steps of material mixing in the mixer truck, ensuring the optimization of the stirring effect.

[0027] In this exemplary embodiment, the mixer truck further includes a water storage tank 6. The water storage tank 6 is connected to the tank body 30 through pipelines and pumps. Specifically, considering the strict requirements for water usage in engineering practice, the designed capacity of the water storage tank 6 should be able to meet the needs of multiple stirrings, avoiding frequent water replenishment and improving construction efficiency. The pipeline design usually includes key components such as inlet valves, outlet valves, and filters to ensure the cleanliness of the water quality and prevent impurities from entering the tank body 30. The pump device, as the power core for transporting the water source, usually adopts a high-efficiency water pump that can provide a stable and continuous water flow rate. During actual use, the operator can control the amount of water to be added according to the characteristics of the material in the tank body 30 and environmental conditions. For example, in a dry environment or when it is necessary to reduce the viscosity of the mixture, an appropriate amount of water can be added to ensure the fluidity and pumpability of the mixture; conversely, in a humid environment or for certain special mixtures, less water or no water may be required. In addition, the design of the water storage tank 6 also allows the mixer truck to operate independently in the absence of an external water source, greatly improving the flexibility and adaptability of the mixer truck. After completing the stirring task, the operator can also use the same system to clean the inside of the tank body 30 to ensure the maintenance and cleanliness of the equipment. In short, the water storage tank 6 and its supporting pipelines and pump devices provide a high degree of flexibility and convenience for the multi-functional excavator loading mixer truck, enhancing the adaptability of the equipment under various engineering conditions, and at the same time improving the accuracy and efficiency of the stirring process.

[0028] In this exemplary embodiment, the mixer truck further includes a support assembly 7. The number of support assemblies 7 is two. The two support assemblies 7 are connected to the middle position of the main frame 10 and symmetrically distributed on both sides of the main frame 10. The support assembly 7 includes a hinge seat 70, a tipping arm 71, and a hydraulic cylinder 72. The hinge seat 70 is fixed to the main frame 10. The tipping arm 71 is rotatably connected to the hinge seat 70. The hydraulic cylinder 72 is rotatably connected to the hinge seat 70 and the tipping arm 71 respectively. Specifically, the hinge seat 70 serves as the basic part of the support assembly 7. It is fixedly connected to the main frame 10 of the mixer truck, providing a firm rotation point. The tipping arm 71 is the extended part of the support assembly 7. One end of it is connected to the hinge seat 70 through a rotating shaft to achieve a rotational connection. This design allows the tipping arm 71 to freely flip within a certain angle range. The hydraulic cylinder 72 plays the role of power transmission. One end is rotatably connected to the hinge seat 70, and the other end is rotatably connected to the tipping arm 71. The design of the hydraulic cylinder 72 allows it to drive the flipping action of the tipping arm 71 through telescoping. When the mixer truck needs to stop and work, the operator can start the hydraulic system to make the hydraulic cylinder 72 start working, pushing the tipping arm 71 to rotate around the connection point with the hinge seat 70. As the hydraulic cylinder 72 extends, the tipping arm 71 gradually flips until the end far from the hinge seat 70 touches the ground. At this time, the center of gravity of the mixer truck is effectively distributed, ensuring that the mixer truck can be stably placed on the ground when mixing materials. The advantage of this design is that it can not only provide stable support on uneven ground or soft soil, but also adapt to different working environments, improving the usage range and adaptability of the mixer truck. At the same time, when the mixing is completed and the mixer truck needs to be moved, the hydraulic cylinder 72 can contract, driving the tipping arm 71 to rotate back to the original position, and the mixer truck can easily return to the driving state without being affected by the support assembly 7 in terms of its mobility.

[0029] In this exemplary embodiment, a grounding seat 73 is provided at one end of the flipping arm 71 away from the hinge seat 70. The grounding seat 73 is rotatably connected to the flipping arm 71 through a rotating shaft. The surface of the grounding seat 73 in contact with the ground during use is a hollow structure, and serrated structures are provided on both sides of the hollow structure. The setting of the flipping arm 71 further enhances the stability of the multi-functional excavator feeding mixer during operation. The grounding seat 73 is the part of the support assembly 7 that specifically contacts the ground. It is provided with serrated structures on the surface in contact with the ground. The serrated structures greatly improve the stability and grip of the mixer on various terrains. When the operator starts the hydraulic cylinder 72 and the flipping arm 71 drives the grounding seat 73 to flip downward until it touches the ground, the serrated structures firmly bite into the soil or other surfaces, ensuring that the mixer remains stable during the mixing process, so that the mixer can maintain good stability even in a relatively complex working environment, thus ensuring the continuity and efficiency of the mixing process. In addition, when the ground is uneven or there are obstacles, the serrations can push aside or pass through small stones, branches and other objects when the grounding seat 73 lands, rather than being blocked by them. Such characteristics further improve the applicability and reliability of the mixer.

[0030] Working principle: First, the driver enters the cab 4. The driver precisely controls the rotation angle and speed of the excavating arm 2 through the operation control system, and accurately feeds the material into the tank body 30. Then, the hydraulic motor 34 is started, and the main shaft 31 begins to rotate, driving the mixing arm 32 fixed on the main shaft 31 to rotate together. The mixing blades 33 generate a flow vortex during rotation, pushing the material in the tank body 30 to perform an efficient circulating motion to increase the contact area with the material and ensure that every particle of the material can be evenly mixed. During the mixing process, if water needs to be added, the operator can control the pump to transport the water in the water storage tank 6 into the tank body 30. When the mixer needs to stop and work, the operator can start the hydraulic system to make the hydraulic cylinder 72 start to work, pushing the flipping arm 71 to rotate around the connection point with the hinge seat 70. As the hydraulic cylinder 72 extends, the flipping arm 71 gradually flips until the grounding seat 73 touches the ground. At this time, the center of gravity of the mixer is effectively distributed, thus ensuring that the mixer can be stably placed on the ground when mixing the material. Finally, when the mixing is completed and the mixer needs to be moved, the hydraulic cylinder 72 can contract, driving the flipping arm 71 to rotate back to the original position, and the mixer can easily return to the driving state.
