Abstract
The utility model relates to a rotary cultivator, which belongs to the field of scarification equipment in agricultural machines, and is suitable for scarifying arable layer soil and pulverizing crop roots. The rotary cultivator adopts an integral girder suspension assembly, wherein, a power input shaft shell bearing of a central gearbox extends forward and upward and is connected with an integral girder, a power input shaft is connected to a cardan drive assembly, and a power output shaft extends out of the central gearbox and is connected with a cutter shaft. Since a plurality of straight gears are reduced from the central gearbox so as to reduce the size of the central gearbox, the utility model has the advantages of low cost and lower weight.
Description
The utility model belongs to scarification equipment field in the agricultural machinery.Be suitable for loose topsoil and pulverize crop root residue.
Prior art, the power of tractor motive power output shaft output after the central tooth roller box, just can be delivered to power take-off connection cutter shaft through the universal joint drive assembly through 1 pair of bevel gear and 3 to 4 spur gears, weak point is that the gear use is many, and gear-box weight is big, cost is high.
The purpose of this utility model is to avoid the prior art weak point and product that a kind of rotovator is provided.
The purpose of this utility model can reach by following measure: rotovator comprises the universal joint drive assembly, and whole girder hangs assembly, central tooth roller box, side bearing, cutter shaft, tulwar, the cultivated shovel of mending-leakage and hood assembly etc.The central tooth roller box is made up of power input shaft, power input shaft cartridge housing, driving bevel gear, driven bevel pinion, power take-off, power take-off lever bearing shell, bearing, oil sealing, casing, case lid and bolt etc., the power input shaft cartridge housing stretches out with whole girder suspension assembly to the front upper place of central tooth roller box and firmly connects, and power take-off stretches out the power take-off lever bearing shell and connects with cutter shaft.The universal joint drive assembly comprises that power transmission shaft, drive-shaft tunnel, latch and isogonism state universal joint etc., and CV joint is made up of overcoat, steel ball, inner race, cover plate and dirt-proof boot.
During the rotary tillage operation, the power of tractor motive power output shaft output is through the universal joint drive assembly, power input shaft, driving bevel gear driven bevel pinion, and power take-off is given the cutter shaft rotary operation transmission of power.
Description of drawings is as follows:
Fig. 1 is the cross-sectional side schematic diagram of rotovator near central tooth roller box place:
Fig. 2 is the CV joint cross-sectional schematic.
Below in conjunction with accompanying drawing embodiment is further described: referring to Fig. 1, the front end of universal joint drive assembly (1) connects with tractor motive power output shaft during operation, the rear end connects with the power input shaft (3) of central tooth roller box, and this moment, whole girder hung assembly (2) and tractor suspension arrangement prolong knot.Power input shaft cartridge housing (4) hangs assembly (2) with whole girder and firmly connects with bolt.Power take-off (5) two ends are stretched out power take-off lever bearing shell (6) and are connected with cutter shaft (7).Referring to Fig. 2, shell (8) sphere inner chamber and inner race (9) sphere movingly, on shell (8) inner chamber on each groove and inner race (9) sphere each groove form 6 to 10 holes, adorn 1 steel ball (10) in each hole.Inner race (9) firmly connects the transmission moment of torsion with power transmission shaft (13).Cover plate (11) is contained in shell (8) and upward stops steel ball (10) to be deviate from.The big end of dirt-proof boot (12) is enclosed within on the shell (8), and small end is enclosed within on the power transmission shaft (13) and prevents that dust from entering.When shell (8) rotates, drive inner race (9) and rotate, drive shell (8) by steel ball (10) when inner race (9) rotates and rotate by steel ball (10).
The utility model has the following advantages than prior art:
1, reduces spur gear transferring power process, simplified gear-box.
2, to adapt to two crossed axis angle scopes big in the CV joint transmission.
3, reduce weight, reduce production costs.
Claims (2)
1, rotovator comprises that universal joint drive assembly, whole girder hang assembly, central tooth roller box, side bearing, cutter shaft, tulwar, the cultivated shovel of mending-leakage and hood assembly, the central tooth roller box is by power input shaft, power input shaft cartridge housing, driving bevel gear, driven bevel pinion, power take-off, power take-off hold shell, casing, case lid, bearing, oil sealing and bolt and form, it is characterized in that the power input shaft cartridge housing stretches out to the front upper place of gear-box hangs assembly with whole girder and connects, and power take-off stretches out the power take-off lever bearing shell and connects with cutter shaft.
2, it is characterized in that the universal joint drive assembly by the described rotovator of claim 1, comprise power transmission shaft, drive-shaft tunnel, latch and CV joint, CV joint is made up of shell, steel ball, inner race, cover plate and dirt-proof boot.
