Abstract
The utility model discloses a chain driving rotary cultivator transmission case, which adopts the short pitch precision chain to replace the gear drive. While the drive performance is increased, the safety and reliability are also increased. The utility model is characterized in that all spur gears of the transmission case of the original rotary cultivator are canceled. The inside of the case body is provided with a pair of bevel gears connected with a power input shaft and two transmission shafts connected by a chain wheel and a chain. By changing the direction of the input power through the bevel gears, the chain wheel and the chain are driven by a first transmission shaft to transmit the input power of the tractor to a second transmission shaft and a cutter shaft. The middle part of the case body is provided with a chain press device which can regulate the tightness of the chain. The utility model has the advantages of small size, light weight, simple structure, low failure rate, easy maintenance, low cost, etc.
Description
Affiliated technical field
The utility model relates to a kind of agricultural machinery, especially a kind of transmission device of rotovator.
Background technology
At present, the rotovator transmission case majority that China produces all is gear-driven, especially be that the matching used rotovator transmission case of large sized tractor gear is just more, modulus is bigger, causes volume weight bigger, and energy-consuming consumptive material is many, and technology and structure are all very complicated, be prone to fault, cannot say for sure to support and safeguard that cost is also higher.
Summary of the invention
In order to overcome the shortcoming and defect of existing rotovator transmission case, the utility model provides a kind of chain drive rotovator transmission case, it adopts the accurate chain of short pitch to replace gear drive, when improving transmission performance, safety and reliability, and volume is little, in light weight, simple in structure, fault rate is low, easy maintenance, has reduced cost.
The technical scheme that its technical problem that solves the utility model adopts is: cancel all spur gears in the former rotovator transmission case, a pair of bevel gear that links to each other with power input shaft and two are set by sprocket wheel and the interconnective power transmission shaft of chain in casing.After changing the input power direction by bevel-gear sett, drive sprocket wheel and accurate chain of short pitch by the I power transmission shaft power of tractor input is reached the II power transmission shaft, drive cutter shaft and finish the rotary tillage operation.For guaranteeing that chain is in optimum Working all the time, at the casing middle part pressure chain device is set, regulate the tightness of chain automatically by spring pressure.The pressing sprocket that this pressure chain device bottom is pressed on the chain is pressed on the chain travelling carriage by pressing the chain sliding axle to be installed in.Press and be provided with regulating spring above the chain travelling carriage successively, support slide and adjust bolt.Pressing sprocket automatically adjusts by regulating spring and the degree of tightness of the reaction force that supports slide to chain.Adjust bolt and can change the automatic working range of pressing the chain device.
The beneficial effects of the utility model are: transmission performance is good, and is safe and reliable, simple in structure, and volume is little, in light weight, be difficult for breaking down, cost is lower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A portion view of transmission case shown in Figure 1.
Fig. 3 is the front view that the utility model medi-spring is pressed the chain device.
Fig. 4 is the right view that spring shown in Figure 3 is pressed the chain device.
Embodiment
With all spur gear cancellations in the former rotovator transmission case.The bevel gear wheel 5 that a bevel pinion 3 that links to each other with power input shaft 1 is set in transmission case casing 2 and cooperates with it, bevel gear wheel 5 and I power transmission shaft 6 are connected as a single entity.After changing the input power direction by big bevel pinion, drive drive sprockets 4, chain 8 and tractor is imported power by I power transmission shaft 6 and reach II power transmission shaft 10, the II power transmission shafts 10 and be connected as a single entity with rotary tiller shaft by movable sprocket 9.For guaranteeing that chain 8 is in optimum Working all the time, a pressure chain device 7 of regulating the chain degree of tightness automatically is set at casing 2 middle parts, the pressing sprocket 15 that this pressure chain device bottom is pressed on the chain 8 is pressed on the chain travelling carriage 14 by pressing chain sliding axle 16 to be installed in.Press and be provided with regulating spring 13 above the chain travelling carriage 14 successively, support slide 12 and adjust bolt 11.Pressing sprocket 15 automatically adjusts by regulating spring 13 and the degree of tightness of the reaction force that supports slide 12 to chain 8.Adjust bolt and can change the automatic working range of pressing chain device 7, make chain 8 be operated in stable state.
