A soil fumigation truck, comprising a chassis (11) with which at least one wheel body (12) for support and movement on the ground and a tank (13) for the substance to be used in fumigation are associated. A pump (15) is functionally connected in input to the tank (13) and its delivery is functionally connected to pipes (18) the outlets (19) of which are located at blades (20), which are rigidly coupled to the chassis (11) and are designed to be driven into the ground to be fumigated. The rotor for actuating the pump (15) is connected directly, for actuation, to the rotation shaft (12a) of the wheel body (12). Downstream of the pump (15) there is a distribution unit (17) from which the pipes (18) branch out. A flow control valve (24) is associated with each pipe, and the distribution unit (17) is provided with an overpressure valve (25) and with a check valve (26) in order to prevent backflow toward the pump (15). |
