Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, specifically to a cement loading device for an integrated mixing pump truck. Background Technology

[0002] As a comprehensive equipment integrating mixing and conveying, the integrated concrete pump truck is widely used in various small and medium-sized engineering scenarios such as rural self-built houses, field operations, and water conservancy construction. Its core advantage lies in its ability to achieve "immediate mixing and pumping upon arrival." In existing technologies, most integrated concrete pump trucks rely on manual labor to pour cement into a loader, which then pours it into the mixer. For example, existing cement feeding solutions mostly use a fixed connection to the mixer body. Even if some adjustable conveying devices can adjust the conveying height, they cannot achieve overall rotation around the mixer, making it difficult to flexibly adjust the relative position of the discharge port and the mixer body. Furthermore, it is difficult to flexibly adjust the contact position and method of the spiral conveying pipe according to the ground elevation, resulting in poor adaptability. At the same time, the size and position of existing spiral conveying devices are relatively fixed. During the transportation of the integrated concrete pump truck, manual disassembly and loading are required, which is time-consuming and labor-intensive, and can easily lead to the problem of the vehicle being too wide. This makes it difficult to adapt to the transportation needs of narrow rural sites or complex road conditions, limiting the site adaptability of the integrated concrete pump truck. Therefore, a material conveying device that can be easily adjusted and adapted to pump trucks is needed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a convenient cement feeding device for an integrated mixing pump truck. By setting a rotating structure, the screw conveyor structure can be adjusted in position by rotating or rotating around the mixer, which solves the problems of difficult loading and unloading, poor flexibility, and difficulty in adapting to narrow spaces in the existing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cement feeding device for an integrated mixing pump truck, which is installed on the mixer body of the integrated mixing pump truck, including a spiral conveying structure connected to the mixer body through a rotating structure; The screw conveyor structure includes a screw conveyor pipe, a conveying screw, and a drive mechanism; the conveying screw is located inside the screw conveyor pipe; the drive mechanism is connected to the conveying screw to realize the upward conveying of materials; The spiral conveyor tube includes a distal end and a proximal end; the spiral conveyor tube is connected to the rotating structure, and the connection point is located near the proximal end; The lower end of the spiral conveyor pipe is equipped with a feeding unit, which has a conical structure. The upper part of the spiral conveyor pipe is equipped with a discharge port; The rotating structure includes a swivel structure that causes the screw conveyor structure to rotate around the mixer body, a horizontally arranged steering shaft connected to the swivel structure, and a rotating structure that enables the screw conveyor structure to rotate around the axis of the steering shaft and to rotate in the vertical plane containing the axis of the steering shaft.

[0005] Furthermore, the feeding unit is a conical cylinder fixedly connected to the lower part of the spiral conveyor pipe.

[0006] Furthermore, the feeding unit includes a base fixedly connected to the lower part of the spiral conveyor pipe, and a feeding cylinder detachably and fixedly connected to the base.

[0007] Furthermore, the rotating structure includes a support frame, and a first roller and a second roller rotatably mounted on the support frame; The support frame includes a horizontally arranged horizontal plate and a vertical plate fixedly connected to the horizontal plate near the spiral conveying pipe; the horizontal plate spans the cylinder wall of the mixer body, and the vertical plate is vertically arranged and located outside the mixer body; the first rolling wheel is rolledly connected to the inner wall of the mixer body; the second rolling wheel is rolledly connected to the outer wall of the mixer body. The rotating structure includes a first connecting block and a second connecting block; One end of the steering shaft is rotatably connected to the support frame, and the other end is fixedly connected to one end of the second connecting block, so that the screw conveying structure can rotate around the axis of the steering shaft; the other end of the second connecting block is rotatably connected to one end of the first connecting block, so that the first connecting block can rotate in the vertical plane where the axis of the steering shaft is located; the other end of the first connecting block is connected to the screw conveying pipe.

[0008] Furthermore, the inner wall of the feed cylinder is equipped with a bag-breaking and piercing mechanism; the bag-breaking and piercing mechanism at the feed inlet includes several radially arranged sharp needles connected to the inner wall of the feed unit; the sharp needles are used to pierce the bag when the cement bag is put in, so that the cement material falls into the vertical screw conveyor pipe.

[0009] Furthermore, it also includes a wheeled bag inserter for feeding the feeding unit, the wheeled bag inserter including a sharp insert bar at the front end and a handle at the rear end for easy pushing.

[0010] Furthermore, the center of gravity of the spiral conveyor is positioned near the steering axis to facilitate rotation and movement around the mixer body.

[0011] Furthermore, a counterweight is provided at the top or bottom of the spiral conveyor pipe to facilitate its rotation and movement around the mixer body.

[0012] Furthermore, a sleeve is fixedly installed at the other end of the first connecting block, and the spiral conveying pipe is rotatably fitted inside the sleeve.

[0013] Furthermore, the spiral conveying pipe is equipped with a pulley or a pull ring, and the mixer body is equipped with a fixed pulley; one end of the rope is fixedly connected to the pulley or pull ring, and the other end is wrapped around the fixed pulley and extends downward.

[0014] Furthermore, a ground wheel is provided at the far end of the spiral conveyor pipe, and the ground wheel is in contact with the ground.

[0015] Furthermore, a discharge port is provided at the far end of the spiral conveyor pipe, and the discharge port is equipped with an opening and closing structure.

[0016] The beneficial effects of this invention are: by setting a rotating structure, the screw conveyor structure can be adjusted in position by rotating or rotating around the mixer, solving the problems of poor mobility and difficulty in adapting to narrow spaces in existing devices. For integrated pump trucks, a unit transport and feeding device would be too cumbersome and increase costs; if the feeding device is directly fixed on the mixer, the vehicle body may become too wide, or it may interfere with other components of the pump truck, such as transport pipelines, during operation. Furthermore, the size of the screw conveyor pipeline may be greatly limited during installation and operation to accommodate other components of the pump truck. Therefore, to ensure sufficient feeding efficiency without affecting other components and to prevent the vehicle body from exceeding width limits, multiple adjustment methods are implemented. The first is a rotating structure that allows the entire feeding device to rotate around the mixer; the second is rotation around the axis of the steering shaft; and the third is rotation within the vertical plane of the axis. These three adjustment methods work together to achieve adjustment in any direction. Finally, the spiral conveyor pipe rotates relative to the sleeve, providing fine-tuning when the discharge port is placed on the support frame. Furthermore, since not all construction sites are flat, these multiple adjustment methods can adapt to various feeding scenarios, allowing for flexible adjustment to suit different ground conditions. Additionally, feeding work that previously required at least two people can now be completed by one person thanks to these structures; the addition of pulleys and ropes further reduces the difficulty of the work.
