Fuel tank with refueling function separated from respiration function

Abstract

The invention discloses a fuel tank with the refueling function separated from the respiration function. The fuel tank comprises a tank body, a fuel tank cover and a respiration device. The fuel tank cover and the respiration device are arranged on the tank body. The respiration device comprises a respiration barrel, a filter, a respiration pipe, a floating ball, a floating ball rod and a floating ball rod positioning plate. The top of the respiration barrel is communicated with the respiration pipe through the filter, the floating ball rod positioning plate with respiration holes is arranged in the respiration barrel, the floating ball rod penetrates through the center of the floating ball rod positioning plate, a check block is arranged at the top of the floating ball rod, the bottom of the floating ball rod is vertically connected to the circle center of the upper surface of the floating ball, the center of the floating ball rod and the ball center of the floating ball are located on the same vertical straight line, and the surface of the floating ball is covered with a sealing gasket. Pressure in the fuel tank and the barometric pressure level off through the respiration device, normal work of a fuel pump and effective control over the fuel injection quantity are facilitated, the respiration device can filter out dust and impurities in air to the maximal degree, and fuel in the fuel tank is prevented from being contaminated by the external dust and impurities.

Description

technical field [0001] The invention relates to an agricultural machinery accessory, in particular to an oil tank with functions of refueling and breathing separated. Background technique [0002] With the rapid development of modern agriculture, people's demand for agricultural machinery is increasing, and the fuel tank is becoming more and more important as an energy supply component in agricultural machinery. The breathing port of the traditional fuel tank is integrated with the fuel tank cover, so dust in the air and Impurities easily enter the fuel tank body through the breathing port of the fuel tank cover, causing pollution to the oil in the fuel tank, thereby affecting the performance of the vehicle. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fuel tank with the functions of refueling and breathing separated. [0004] In order to achieve the above purpose, a fuel tank with separate refueling and breathing functions includ...
