FERTILIZER APPLICATOR HAVING AUTOMATIC MOVEMENT FOR HILLY LAND

摘要

A fertilizer applicator having automatic movement for a hilly land comprises a supporting arm (9), a power mechanism (10) and a fertilizer application mechanism (1). The power mechanism (10) comprises a motor (1003) provided at the foremost end of the supporting arm (9). A front gear box (1001) is provided in front of the supporting arm (9). An output shaft (1004) of the motor (1003) is transmissionally-connected to a first drive gear (1006). The first drive gear (1006) is transmissionally-connected to two first driven gears (1008). Centers of the two first driven gears (1008) and the first drive gear (1006) are on the same straight line. The fertilizer application mechanism (1) comprises a supporting frame (104). The supporting frame (104) is transmissionally-connected to one of the first driven gears (1008). The supporting frame (104) is slidably connected to a hollow vibrating excitation rod (105). A middle connection plate (109) is provided above the supporting frame (104). A lower side of the middle connection plate (109) is provided with a hollow air-liquid flow block (106). The vibrating excitation rod (105) is connected to the air-liquid flow block (106). A bottom portion of the vibrating excitation rod (105) is connected to a first soil penetration device (102). The first soil penetration device (102) is in communication with an internal cavity of the vibrating excitation rod (105) and has an air discharge and liquid application hole (115) in communication with the atmosphere. The fertilizer applicator having automatic movement can move automatically and has high fertilizer application efficiency.
