The invention discloses a centrifugal-type tree protectant spray brushing
machine which consists of three major parts, including a driving
system, a protectant supplying
system and a centrifugal-type spray brushing
system. A protectant
storage tank (1) and a driving motor (3) are installed on a
cart (17), and a transmission soft shaft (5) is driven by the driving motor (3) to form two branches at a transmission shunt chamber for the purpose of respectively driving two groups of four centrifugal throwing rollers (7, 8) which are mutually connected in series; a material supplying pump arranged inside the protectant
storage tank (1) is used for conveying a protectant to a flow control valve through a conveyance hose (4), the protectant is then divided into two branches which respectively fall, through a flow guide opening on a guide
protective shield (12), onto the surfaces of the centrifugal throwing rollers (7, 8) rotating at a high speed, and the protectant is spray-brushed on the
trunk at a certain initial speed under the action of
centrifugal force. The centrifugal-type tree protectant spray brushing
machine of the invention has the characteristics of strong self adapting capability, high working efficiency, simpleness in operation and the like, and can be used for spray-brushing the tree protectant on the
trunk during park and garden maintenance.
