To the technical problem, the utility model provides a preceding power take-off output device of agricultural wheeled tractor.
A front power take-off output device of an agricultural wheeled tractor comprises a mounting plate fixed at the front end of a tractor frame and a power reduction box fixed on the mounting plate; the power reduction gearbox is provided with a control system for power output and cutting off, an input shaft of the power reduction gearbox is connected with a crankshaft of the diesel engine of the tractor through a universal joint transmission shaft, and an output shaft of the power reduction gearbox is connected with a gearbox of a matched agricultural implement through the universal joint transmission shaft.
Preferably, the power reduction gearbox is provided with a mounting bracket, and the mounting bracket is detachably connected with the mounting plate through a fastener; the universal joint transmission shaft is detachably connected with the power reduction gearbox through a connecting flange and a fastener.
Preferably, the control system adopts a gear shifting operating handle or a pneumatic control system.
The utility model has the advantages that: 1. the front end of the tractor is provided with a front power take-off output device, power is directly taken off from a crankshaft of a diesel engine, the power of the diesel engine is output from an output shaft after being decelerated and twisted through a power reduction box and is used for driving a gearbox of matched agricultural equipment, so that the tractor can be provided with matched agricultural equipment such as a mower, a sugarcane harvester, a ditcher, a fertilizer box and the like at the front end, the operation range and the accumulated operation time of the tractor are greatly improved, and the tractor can be fully utilized; 2. the power is directly taken from the crankshaft of the diesel engine through the universal joint transmission shaft, the transmission efficiency is high, and the front power taking output performance can reach 85% of the total power of the diesel engine; the mechanical transmission is compact in arrangement, simple in structure and convenient to maintain; 3. the power reduction box is detachably arranged at the front end of the tractor, and can be adjusted or replaced according to the requirements of users so as to meet the output requirements of users on different rotating speeds and different rotating directions.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
the figures in the drawings represent:
1. the tractor comprises a tractor frame 2, a mounting plate 3, a power reduction gearbox 4, an input shaft 5, a universal joint transmission shaft 6, a crankshaft 7, an output shaft 8, a PTO output shaft 9, a mounting bracket 10, a connecting flange 11 and a gear shifting control handle.
Detailed Description
The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
As shown in fig. 1, the front power take-off output device of the agricultural wheeled tractor comprises a mounting plate 2 fixed at the front end of a tractor frame 1 and a power reduction box 3 fixed on the mounting plate 2. An input shaft 4 of the power reduction gearbox 3 is connected with a crankshaft 6 of a tractor diesel engine through a universal joint transmission shaft 5 so as to transmit the power of the diesel engine to the power reduction gearbox 3. The power reduction box 3 adopts one-stage or two-stage speed reduction, and transmits power from the input shaft 4 to the output shaft 7 through gear meshing transmission. The tail end of the output shaft 7 is provided with a PTO output shaft 8, and the PTO output shaft 8 is connected with a gearbox of a matched agricultural implement through a universal joint transmission shaft (not shown in the figure), so that power is transmitted to the agricultural implement from the output shaft 7, the whole process of outputting the power of the diesel engine to the agricultural implement is realized, and the purpose of taking power from the diesel engine is achieved.
The power reduction box 3 is provided with a mounting bracket 9, and the mounting bracket 9 is detachably connected with the mounting plate 2 through fasteners such as bolts and the like. The universal joint transmission shaft 5 is detachably connected with the power reduction gearbox 3 through fasteners such as a connecting flange 10, bolts and the like. The power reduction box 3 can be adjusted or replaced according to the requirements of users during installation so as to meet the output requirements of users on different rotating speeds and different rotating directions.
The power reduction gearbox 3 is provided with a control system for power output and cut-off, the control system can adopt a mechanical gear-shifting control handle 11 and can also be changed into a pneumatic control system (not shown in the figure) according to the requirements of users so as to realize remote control of the power reduction gearbox 3 in a cab and meet the control requirements of power output and cut-off.
The utility model discloses power take-off output device before the front end installation of tractor to the direct bent axle 6 power take-off from the diesel engine, pass through power reducing gear box 3 speed reduction with the power of diesel engine and increase the output from output shaft 7 after turning round for the gearbox of the supporting agricultural implement of drive makes the tractor can install agricultural implements such as supporting lawn mower, sugarcane harvester, ditching machine, fertilization case at the front end, has improved the operation scope and the accumulative total operating time of tractor greatly, makes the tractor can obtain make full use of. Because the mounting and using requirements of all matched agricultural implements are different, part of the agricultural implements need to be matched with the front power take-off output device of the tractor for use when being mounted and used, so as to meet the operation requirements of the agricultural implements.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
