AI Technical Summary

Technical Problem

The thermal insulation effect of the external top cover of the existing tractor is poor, resulting in an increase in the internal temperature of the cab, affecting the driver's comfort and safety.

Method used

An outer top cover with thermal insulation function is designed, including an upper case and a lower case. A heat insulation groove is provided inside the upper case, and a heat dissipation fan and a heat insulation component are provided on the lower case. Combined with an insulation layer and a heat insulation film, it effectively isolates and dissipates heat.

Benefits of technology

Through the cooperation of heat insulation grooves, cooling fans and insulation components, heat is effectively prevented from entering the cab, and air is circulated through the heat sink fan, reducing the internal temperature of the cab, and improving the driver's comfort and safety.

Abstract

The utility model relates to the technical field of tractors, and provides an outer top cover with a heat insulation function, which comprises a top cover body, the top cover body comprises an upper shell and a lower shell, the upper shell is fixedly connected with the lower shell, the upper shell is of a cylindrical structure, the upper shell is internally provided with heat insulation grooves, the heat insulation grooves are sequentially arranged along the circle center of the upper shell, and the heat insulation grooves are communicated with the upper shell. An observation hole is communicated with the upper shell and the lower shell, a skylight is arranged in the observation hole and hinged to the upper shell, a heat insulation layer is fixedly connected to the upper portion of the upper shell, a heat dissipation groove is formed in the side, back on to the upper shell, of the lower shell, a heat dissipation fan is fixedly connected into the heat dissipation groove, and a ventilation hole is formed in the side, away from the heat dissipation groove and the upper shell, of the lower shell. The ventilation hole is communicated with the mounting groove, and a sliding groove is further formed in the side, back on to the upper shell, of the lower shell. By means of the technical scheme, the problems that in the prior art, an outer top cover is poor in heat insulation effect, the temperature in a cab rises, a driver feels uncomfortable, and driving safety is affected are solved.
