Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A land wheel monomer combining power transmission clutch and speed change of a traction type seeder comprises a land wheel frame 2, a step pulley transmission 4 and a double-jaw synchronous clutch 9, a land wheel assembly 1 is rotatably arranged at the lower end of the land wheel frame 2, a chain wheel A10 is fixedly arranged on a wheel shaft of the land wheel assembly 1, a connecting frame 5 is hinged and arranged at the upper end of the land wheel frame 2 through the double-jaw synchronous clutch 9 in a reciprocating swinging manner, the step pulley transmission 4 and the double-jaw synchronous clutch 9 are assembled on the inner side part of the connecting frame 5, a chain wheel B11 and a chain wheel C7 are fixedly arranged on the outer end parts of a land wheel power input shaft 9-1 and a land wheel power output shaft 9-2 of the double-jaw synchronous clutch 9 respectively, a chain wheel D13 is fixedly arranged on a speed change power input shaft 4-2 of the step pulley transmission 4, a chain B6 is sleeved on the chain wheel C7 and a chain wheel D13, a chain A12 is sleeved on the chain wheel A10 and a chain wheel B11, the back side part of the connecting frame 5 is provided with a bidirectional hydraulic oil cylinder 3 in a swinging hinged mode, and an oil cylinder rod of the bidirectional hydraulic oil cylinder 3 is hinged with the ground wheel frame 2.
When in fertilizing and seeding operation, the single body is assembled on a frame of a traction type seeder by using a connecting frame 5, a variable speed power output shaft 4-1 of a cone pulley transmission 4 is connected with a fertilizing shaft and a seeding shaft and moves forward randomly, the rotating power of a land wheel assembly 1 is transmitted to a land wheel power input shaft 9-1 of a double-jaw synchronous clutch 9 through a chain wheel A10, a chain A12 and a chain wheel B11, the double jaws of the double-jaw synchronous clutch 9 are in a meshing state at the moment, the rotating land wheel power input shaft 9-1 drives the rotating power to rotate through a land wheel power output shaft 9-2, a chain wheel C7, a chain B6 and a chain wheel D13 in sequence to drive a variable speed power input shaft 4-2 of the cone pulley transmission 4 to rotate, and after the speed is changed by using the cone pulley transmission 4, the rotary power is transmitted to the fertilizing shaft and the seeding shaft by the variable speed power output shaft 4-1 to complete power transmission and variable speed operation.
