Problems solved by technology

The disadvantages of this speed change method are: 1. The deceleration path is long, resulting in a large volume of the gearbox; 2. The deceleration path is long, the step-by-step deceleration structure is complicated, and the power loss is large; 3. Because the speed is finally transmitted to the driving shaft of the traveling mechanism and Before the power output shaft, it has been decelerated step by step, so the output power of the power output gear will be restricted by the gear coefficient ratio of the previous deceleration, so that the power of the supporting agricultural machinery is limited

Abstract

The invention provides a minitype tiller gearbox which relates to farm machinery, in particular to a transmission mechanism for a minitype tiller. The minitype tiller gearbox comprises a box body and a gear arranged on a shaft, wherein the shaft arranged on the box body comprises an input shaft, a power output shaft, an extension shaft and two travel driving shafts; wherein the portion of the input shaft extending into the box body is fixedly provided with a main driving gear and a slippage gearshift duplicate gear; the power output shaft is fixedly provided with a main driven gear and a power output gear; a reverse gear duplicate gear is sleeved on a shaft between the main driven gear and the power output gear; a duplicate adapter gear is fixedly arranged at the middle of the extension shaft; two adapter gears are respectively sleeved at the left and right sides of the duplicate adapter gears; a pressure spring is arranged at the outside of the adapter gear; and the part of the travel driving shaft extending into the box body is fixedly provided with a travel driving gear. The invention has the advantages of compact structure, little power consumption and reasonable design of thetransmission structure.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a transmission mechanism for a miniature cultivator. Background technique [0002] The speed change mode of the existing miniature cultivator gear box is: the rotating speed of the input shaft is first decelerated step by step through several gear pairs, and then the drive shaft and the power output shaft of the transmission traveling mechanism. The disadvantages of this speed change method are: 1. The deceleration path is long, resulting in a large volume of the gearbox; 2. The deceleration path is long, the step-by-step deceleration structure is complicated, and the power loss is large; 3. Because the speed is finally transmitted to the driving shaft of the traveling mechanism and The power output shaft has been decelerated step by step before, so the output power of the power output gear will be restricted by the gear coefficient ratio of the previous deceleration, so that the power ...
