Description

Technical Field

[0001] This utility model relates to the field of leveling machine technology, specifically to a leveling machine housing structure with an air-cooled guide groove. Background Technology

[0002] The main function of a screed is to level the surface of an object. It is commonly used for leveling the surface of metal sheets and cement roads. It uses the squeezing action of upper and lower rollers to level the surface of uneven metal sheets or cement roads to achieve the required flatness.

[0003] Existing screed shell designs are unreasonable and complex, typically featuring a fully enclosed design that hinders the active dissipation of heat released during operation. This leads to heat buildup after prolonged use, negatively impacting the stable operation of internal components. Furthermore, existing screed shells are secured with screws and other parts during assembly, requiring screw-driving equipment, which increases assembly steps and costs. Therefore, the inventors have improved the screed shell structure by incorporating air-cooled airflow channels. Utility Model Content

[0004] The purpose of this utility model is to provide a screed housing structure with an air-cooled guide groove. This screed housing structure has a simple structure and reasonable design. It can introduce the hot air generated during the operation of the screed into the stepped groove through the guide hole, and finally release it to the outside through the heat exhaust hole, thereby achieving the effect of air cooling and guiding, reducing the ambient temperature inside the screed, so that all components can work stably. It also achieves screwless and tool-free installation, simplifies the assembly process, reduces the use of equipment, and helps to reduce production costs. It solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screed housing structure with air-cooled guide channels. The screed housing structure includes a main housing and a bottom housing disposed on the main housing. The bottom housing serves as a support plate for the screed, supporting the entire screed. The main housing includes a top cover plate and an outer frame fixed to the lower end face of the top cover plate. The outer frame is a hollow cavity with openings at both ends. All parts of the screed are installed in the cavity of the outer frame. Multiple sets of air-cooled guide channels are provided on the outer frame, and multiple extension seats are fixed to the lower end face of the outer frame. The air-cooled guide channels include channels fixed inside the outer frame, and the channels are hollow cavities with openings at both ends. Multiple sets of air-cooled guide channels are distributed on the four sides of the outer frame. The bottom housing includes a bottom plate and a protruding plate fixed to the upper end face of the bottom plate. An assembly slot is provided on the upper end face of the protruding plate, and the extension seats are inserted into the assembly slot. In this embodiment, four extension seats and four assembly slots are provided.

[0006] Preferably, the tank body has a stepped groove and drainage holes and heat exhaust holes located on both sides of the stepped groove. The drainage holes and heat exhaust holes are inclined. The heat generated by the leveling machine during operation will be released into the air, heating the air. The hot air will rise and enter the stepped groove through the drainage holes, and finally be released to the outside through the heat exhaust holes, achieving the effect of air cooling and air guiding. The height value of the stepped groove is larger on the side of the stepped groove near the drainage hole and smaller on the side of the stepped groove near the heat exhaust hole, which can intercept dust and play a certain role in dust prevention in the internal space of the outer frame.

[0007] Preferably, a fixing rod is fixed inside the heat dissipation hole. The fixing rod is horizontally set, and both ends of the fixing rod are fixedly connected to the outer frame.

[0008] Preferably, multiple rotating shafts are installed on the fixed rod at equal intervals along the horizontal direction, and guide vanes are connected to each of the multiple rotating shafts. The multiple guide vanes can rotate with the rotating shafts, thereby changing the orientation of the guide vanes and thus changing the direction of hot air discharge, releasing the hot air from a specified angle.

[0009] Preferably, the extension seat includes a seat body and pads and positioning rods respectively fixed at both ends of the seat body, and an inclined block is fixed in the assembly groove, with the inclined block in close contact with the pad.

[0010] Preferably, a positioning groove is provided on the side of the assembly groove away from the inclined block, and the positioning rod is engaged in the positioning groove. Therefore, the base can be fixed in the assembly groove by the positioning rod, so that the main shell and the bottom shell are assembled into one piece, eliminating the trouble of using screws for fixing, simplifying the assembly process and reducing costs.

[0011] Preferably, the inclined block is inclined at one end near the pad, with the inclination angle between 75° and 85°. During the process of the seat entering the assembly groove, the pad will be squeezed by the inclined block, which will cause the positioning rod to be squeezed into the positioning groove more smoothly. In this embodiment, the inclined block, pad and positioning rod are all made of rubber and have a certain deformation capability.

A positioning groove is provided on the side of the assembly groove away from the inclined block. The positioning rod is engaged in the positioning groove. During assembly, by inserting the four seats into the four assembly grooves, the four inclined blocks squeeze the four pads, and the four positioning rods are squeezed into the four positioning grooves respectively, the fixed connection between the main shell and the bottom shell is completed. The parts of the leveling machine are set inside the whole formed by the main shell and the bottom shell. Through the above operation, screwless and tool-free installation can be achieved, thus simplifying the assembly process, reducing the use of equipment, and thus helping to reduce production costs.
