Abstract

The utility model discloses a rotary tilling machine transmission, comprising an enclosure in which a spline shaft, a first shaft, a second shaft and an output shaft are arranged in parallel; a duplicate gear is arranged on the spline shaft; a high-speed wheel, a low-speed wheel and a middle wheel are arranged on the first shaft; an intermediate wheel is arranged on the second shaft and meshed with the middle wheel; a driving wheel is arranged on the output shaft and meshed with the intermediate wheel; a transmission fork is arranged on the duplicate gear; a gear shift lever is arranged on the enclosure and connected with the transmission fork. An output rotational speed of a cutter shaft can be regulated through the gear shift lever, the spline shaft and the duplicate gear to change a torsion moment; when people cultivate a farmland with soft soil or a farmland with a large quantity of crop stubbles and weeds, the high rotational speed and the small torsion moment can be outputted by the cutter shaft, thereby shortening the cultivation time and reducing the energy consumption; when people cultivate a farmland with hard soil, a lower rotational speed and a large torsion moment can be output by the cutter shaft, thereby improving the cultivation quality. Therefore, the rotary tilling machine transmission can solve the problems of low cultivation efficiency and poor cultivation quality in the prior art caused by no realization of the conversion of the rotational speed.

Description

The rotary tillage mechanical transmission

Technical field

The utility model relates to a kind of speed change gear of farm machinery, particularly relates to a kind of rotary tillage mechanical transmission.

Background technique

At present, existing various agriculture rotary tillage machineries on the market, its cutter shaft can only be exported constant rotational speed, and in cultivating procedure because the soft degree difference of arable land soil property, people also are not quite similar to the requirement of the output speed of cutter shaft, for example when the more arable land of the softer arable land of farming soil property or farming crop cover and weeds, need cutter shaft export the little moment of torsion of high rotating speed, to accelerate ploughing speed, improve farming efficient, to save energy consumption; When the more solid arable land of farming soil property, need cutter shaft output low rotation speed large torque, to improve cultivating quality, still, existing rotary tillage machinery can't be realized the conversion of rotating speed, causes that farming efficient is low, the problem of cultivating quality difference, can't satisfy people's user demand.

Summary of the invention

The purpose of this utility model, provided a kind of rotary tillage mechanical transmission, people utilize it can be according to different tillage requirements, adjust the output speed and the moment of torsion of agriculture rotary tillage machinery cutter shaft, can improve farming efficient, shorten the farming time, improve cultivating quality, reasonably utilize the output power of motor, satisfy people's usage requirement.

The utility model is achieved through the following technical solutions: the rotary tillage mechanical transmission comprises casing, parallel installation splined shaft, first, second and output shaft in the casing, duplicate gear is installed on the splined shaft, is gone up for first wheel, low speed wheel and breast wheel at a high speed are installed, go up for second idle wheel is installed, idle wheel and breast wheel engagement, drive wheel is installed on the output shaft, and shift fork is installed in drive wheel and idle wheel engagement on the duplicate gear, shift level is installed on the casing, and shift level is connected with shift fork.

For further realizing the purpose of this utility model, can also realize by the following technical solutions: input shaft is installed on the casing, the axial direction of input shaft is vertical with the axial direction of splined shaft, first bevel gear is installed on the input shaft, second bevel gear is installed, first bevel gear and the engagement of second bevel gear on the splined shaft.The gear shift positioning device is installed on the shift level, the gear shift positioning device is connected and composed by ball and Returnning spring under housing, holding down bolt, the last ball, offer cavity in the housing, in the cavity from top to bottom successively the installing and locating bolt, go up ball, ball and Returnning spring down, shift level passes cavity and contacts with following ball with last ball respectively.

Good effect of the present utility model is: it can pass through the output speed change moment of torsion that shift level, splined shaft and duplicate gear are regulated cutter shaft, when the more arable land of the softer arable land of people's farming soil property or farming crop cover and weeds, the little moment of torsion of the exportable high rotating speed of cutter shaft shortens the farming time, improves farming efficient, reduces energy consumption; When the harder arable land of farming soil property, the exportable low rotation speed large torque of cutter shaft improves cultivating quality, thereby will satisfy the different tillage requirements of people.
