The application provides a heating type evaporation and infiltration instrument, and relates to the field of ecological environment detection. The heating type evaporation and infiltration instrument comprises an evaporation and infiltration unit, a detection unit and a water supplementing unit. The evaporation and infiltration unit comprises an outer barrel, an inner barrel, a heating module and a weighing sensor. The outer barrel is sleeved on the outer barrel. The top of the inner barrel is provided with a rain collecting opening. The heating piece of the heating module is used for being attached to the inner barrel, and is used for heating the undisturbed soil stored in the inner barrel. The weighing sensor is installed on the outer barrel, and the weighing sensor bears the inner barrel. The detection unit is used for obtaining the test parameters of the undisturbed soil. The water supplementing unit is connected with the evaporation and infiltration unit, and is used for supplying water to the inner barrel. When the heating wire infiltration instrument operates, the difference between the test simulation environment and the actual environment of the undisturbed soil can be reduced, and the accuracy and reliability of the test result can be improved.

The utility model relates to a kind of grain barn inner circulation uniform temperature ventilation system, including grain barn and the center pipe being set in the middle part of grain barn, further including ventilation pipe, upper air collecting chamber, lower air collecting chamber, ventilation ground groove, center ventilator and uniform temperature fan;Ventilation pipe is fixedly arranged on the lateral wall of center pipe;Upper air collecting chamber is communicated with the upper end of ventilation pipe;The air supply pipeline of center ventilator and uniform temperature fan is all communicated into upper air collecting chamber, center ventilator and uniform temperature fan extract air from the top inside grain barn, then output into upper air collecting chamber, lower air collecting chamber is communicated with the lower end of ventilation pipe;Ventilation ground groove is opened in the bottom of grain barn, and ventilation ground groove is communicated with lower air collecting chamber, so that uniform temperature airflow can be vertically downward along ventilation pipe and reach lower air collecting chamber and ventilation ground groove located in bottom, uniform temperature ventilation is carried out to grain from bottom to top, form inner circulation located in grain barn, avoid heat loss and energy efficiency reduction caused by long-distance transportation of traditional external air pipe, improve economy and environmental protection.
