Description

Mechanical gearbox for salt harvester

Technical Field

The utility model relates to a salt collecting mechanical equipment, in particular to a mechanical gearbox for a salt collecting machine.

Background

When the driver releases the accelerator pedal during the running process of the automobile, the engine speed begins to drop, the automobile is in a sliding state, and if the speed of the automobile is high and the hydraulic torque converter is in a locking state, the transmission path of the engine braking force is the shell → the locking clutch → the turbine → the gearbox → the wheels. If the vehicle speed is low, the torque converter is in the unlocked state, and the engine braking force is generated by the housing → the pump wheel → the turbine wheel → the transmission case → the wheel, in the pump → turbine process, it is realized by stirring the hydraulic oil, so that no matter the vehicle speed is high or low, when a driver releases a brake pedal, the braking force of an engine is transmitted to wheels, so that the speed of the vehicle is reduced rapidly, (in an automatic gearbox, a one-way clutch is arranged in a single gear, but due to the limitation of volume and cost, the one-way clutch cannot be arranged in each gear, the gears with the one-way clutches are all in a high gear, although the vehicle can slide in the high gear with low resistance, the speed of the vehicle is reduced slowly, once the vehicle reaches a low gear, the braking force of the engine is inserted rapidly, so that the speed of the vehicle is reduced rapidly, the sliding distance is greatly reduced, and the phenomenon of downshift and contusion of parts of the gearbox can be caused). Although the existing engine has a reverse dragging fuel cut-off technology (under the condition that an accelerator is loosened, the vehicle can drive the engine to run, and the engine stops injecting fuel to reduce fuel consumption within a certain vehicle speed range), the engine braking force after fuel cut-off is large, the vehicle speed is reduced quickly, the sliding distance is greatly shortened, and the engine can recover fuel supply quickly to maintain running, so the fuel cut-off time is very short, in addition, for example, in some gentle slopes, an automatic transmission type only can idle and creep under the action of the engine braking force, so even an accelerator is needed to be stepped on to descend, a manual gear can be completely disengaged to disconnect the power of the engine and a gearbox, so the engine is in an idle state, the vehicle can downwards slide by means of gravity and self inertia, the vehicle speed is increased quickly, the sliding distance is long, and therefore, the sliding distance of the automatic transmission type is increased, the power connection between the engine and the wheels needs to be cut off in time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a receive salt machine and use mechanical gearbox to solve the big problem of current gearbox energy consumption.
