Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete conveying, in particular to a new type of U-shaped finished concrete screw conveyor. Background Technique
[0002] The concrete screw conveyor is specially designed for concrete mixing plants and is an efficient screw conveying device. Due to the large self-weight and easy-to-bond characteristics of concrete, during the screw conveying process, it is easy to adhere to the inner and outer tube walls of the screw conveyor, which not only increases the load on the motor but may also cause the motor to burn out in extreme cases. In addition, the cleaning work is quite difficult. Since the finished concrete contains a high content of sand and gravel and a certain amount of moisture, during the conveying process, these sand, gravel and moisture will also cause wear to the blades and inner tube of the screw conveyor, further shortening the service life of the equipment.
[0003] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a new type of U-shaped finished concrete screw conveyor. Content of the Utility Model
[0004] The purpose of the utility model is to provide a new type of U-shaped finished concrete screw conveyor to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A technical solution of a new type of U-shaped finished concrete screw conveyor includes a conveyor housing. A cover plate is arranged above the conveyor housing. A feed inlet is installed at the top left of the conveyor housing. A discharge outlet is arranged at the bottom right of the conveyor housing. A screw conveying mechanism is installed inside the conveyor housing. The screw conveying mechanism includes a hydraulic motor installed on the conveyor housing. The output end of the hydraulic motor is connected to a screw cylinder through a transmission kit. The screw cylinder is located inside the conveyor housing. A screw blade is arranged outside the screw cylinder. Transmission connection ends and bearing connection ends are respectively arranged at both ends of the screw cylinder. The transmission connection end is connected to the transmission kit. A bearing seat is arranged outside the bearing connection end. The bearing seat is connected to the conveyor housing.
[0007] As a preferred technical solution, the bottom of the conveyor housing is arranged in an arc shape. An inner arc-shaped lining plate is arranged on the inner wall of the bottom of the conveyor housing. An inner lining plate is arranged above the inner arc-shaped lining plate.
[0008] As a preferred technical solution, both the inner arc-shaped lining plate and the inner lining plate are connected to the housing through assembly bolts.
[0009] As a preferred technical solution, brackets are arranged on the outer walls on both sides of the conveyor housing.
[0010] As a preferred technical solution, a cover is provided outside the transmission kit.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model is a new type of U-shaped screw conveyor for finished concrete products. The U-shaped structure can more effectively prevent the side leakage and adhesion of concrete during the conveying process. When conveying concrete, the traditional linear screw conveyor is prone to accumulation on both sides of the conveyor due to the dead weight and viscosity of the concrete, which increases the difficulty of cleaning and energy consumption. The U-shaped design cleverly uses the effect of gravity to make the concrete naturally gather towards the center during the conveying process, reducing the attachments on the side walls, thereby improving the conveying efficiency and reducing the load.
[0013] In addition, hydraulic motors are used as power sources. Compared with traditional motor drives, hydraulic motors have higher torque output and better overload protection capabilities. When conveying highly viscous and high-density materials such as concrete, hydraulic motors can more effectively overcome resistance and ensure the stable operation of the conveyor. At the same time, the speed regulation performance of hydraulic motors is also more superior, and can be flexibly adjusted according to actual conveying needs, further improving the adaptability and work efficiency of the conveyor.
[0014] In addition, the utility model also adopts the design of assembled inner arc lining plate and inner side lining plate. These lining plates not only have excellent wear resistance, which can effectively extend the service life of the conveyor, but also can be conveniently installed on the inner wall of the conveyor shell through assembly bolts, which is convenient for later maintenance and replacement. This design not only reduces production costs and maintenance difficulties, but also improves the overall performance and reliability of the conveyor.
[0015] The utility model has the advantages of reasonable structure, high conveying efficiency, convenient maintenance, etc., and can effectively solve the problems existing in the process of conveying concrete by traditional screw conveyors. The equipment has broad application prospects and promotion value in occasions such as concrete mixing stations. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0020] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the attached drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.
[0021] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a technical solution for a new type of U-shaped concrete finished product spiral conveyor: including a conveyor housing 1, a cover plate 13 is arranged above the conveyor housing 1, a feed inlet 11 is installed at the top left of the conveyor housing 1, a discharge outlet 12 is arranged at the bottom right of the conveyor housing 1, a spiral conveying mechanism is installed inside the conveyor housing 1, and the spiral conveying mechanism includes a hydraulic motor 21 installed on the conveyor housing 1. The output end of the hydraulic motor 21 is connected to a spiral cylinder 24 through a transmission kit 22. The spiral cylinder 24 is located inside the conveyor housing 1. A spiral blade 25 is arranged outside the spiral cylinder 24. Drive connection ends 241 and bearing connection ends 242 are respectively arranged at both ends of the spiral cylinder 24. The drive connection end 241 is connected to the transmission kit 22. A bearing housing 26 is arranged outside the bearing connection end 242, and the bearing housing 26 is connected to the conveyor housing 1.
[0022] In this embodiment, the hydraulic motor 21 is relied on to provide power, and the power is transmitted to the spiral cylinder 24 through the transmission kit 22. After the spiral cylinder 24 receives the power, the spiral blade 25 thereon starts to rotate, forming a continuous conveying channel. This channel starts from the feed inlet 11 and extends along the inside of the conveyor housing 1 to the discharge outlet 12.
[0023] When the materials enter the conveyor housing 1 from the feed inlet 11, they will fall on the rotating spiral blade 25. As the spiral blade rotates, the materials are pushed towards the direction of the discharge outlet 12. The design of the spiral blade ensures that the materials can maintain a stable flow during the conveying process, avoiding problems of blockage and accumulation.
[0024] In addition, by adjusting the output power of the hydraulic motor 21, the rotation speed of the spiral cylinder 24 can be changed, thereby achieving precise control of the material conveying speed. This flexibility enables the screw conveyor mechanism to adapt to the conveying requirements under different working conditions.
[0025] Wherein, the bottom of the conveyor housing 1 is arranged in an arc shape, an inner arc-shaped lining plate 102 is arranged on the inner wall of the bottom of the conveyor housing 1, an inner side lining plate 101 is arranged above the inner arc-shaped lining plate 102, and both the inner arc-shaped lining plate 102 and the inner side lining plate 101 are connected to the housing through assembly bolts 15.
[0026] In this embodiment, the arc-shaped bottom design of the conveyor housing 1 not only optimizes the material flow path but also enhances the overall stability and durability of the equipment. The adoption of the inner arc-shaped lining plate 102 effectively reduces the direct contact between the material and the bottom of the conveyor housing during transportation, reduces wear, and prevents material accumulation at the bottom.
[0027] Wherein, brackets 14 are arranged on the outer walls on both sides of the conveyor housing 1.
[0028] In this embodiment, the brackets 14 are fixed on the outer walls on both sides of the conveyor housing 1, providing additional support force for the conveyor.
[0029] Wherein, a hood 23 is arranged outside the transmission kit 22.
[0030] In this embodiment, the finely designed hood 23 outside the transmission kit 22 plays a protective role, ensuring its durability and stability in a harsh working environment.
[0031] The working principle and usage process of the present utility model: After the present utility model is installed, it works according to the above embodiments until all working steps are completed.
