Technical Field

The invention relates to the technical field of non-movable special tool manufacturing, in particular to a clutch control device for a non-movable snow sweeper.

Background

Most of the current non-movable snow sweeper clutches use a manual lever type clutch push rod to enable an engine to be separated from and attracted by a clutch in a power take-off assembly to transmit power; the whole set of control device only comprises simple components such as a push rod and the like; during manual operation, the clutch has large working rotation inertia and needs to be quickly attracted, and if the clutch is improperly operated, the clutch friction plate is easily burnt, so that safety accidents are easily caused.

Disclosure of Invention

The invention aims to provide a clutch control device of a snow sweeper, which can solve the problems that clutch friction plates are easy to burn out and safety accidents are easy to cause in the prior art.

In order to solve the problems, the invention adopts the technical scheme that: the clutch control device of the snow sweeper comprises an electric push rod arranged at a flywheel shell of a non-movable snow sweeper, wherein the electric push rod controls the suction and separation of a clutch in a power take-off assembly through the push rod, and an electric cabinet used for controlling the electric push rod is arranged at one end of the power take-off assembly.

In the above technical solution, a more specific solution may also be: the electric cabinet comprises a first relay, a second relay, a third relay and a fourth relay, wherein one end of a coil of the first relay is connected with one end of a coil of the third relay in parallel and then connected with a clutch separation signal end, one end of a coil of the second relay is connected with one end of a coil of the fourth relay in parallel and then connected with a clutch suction signal end, the other end of the coil of the first relay is grounded, the other end of the coil of the third relay is grounded, the other end of the coil of the second relay is grounded, the other end of the coil of the fourth relay is grounded, one end of a normally open contact of the first relay is connected with the positive electrode of an output power supply through a first diode, the other end of the normally open contact is respectively connected with one end of the normally open contact of the second relay and one end of a storage battery, and the other end of the normally open contact of the second relay is connected with the negative electrode of the output, and one end of a normally open contact of the third relay is connected with one end of a normally open contact of the fourth relay in parallel and then is grounded, the other end of the normally open contact of the third relay is connected with the cathode of the second diode, and the other end of the normally open contact of the fourth relay is connected with the cathode of the first diode.

Further: the telescopic stroke of the electric push rod is 100-150 mm.

Further: the electric push rod is connected with the push rod through a connecting piece.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the beneficial effects that: because the invention is provided with the electric push rod, the power is transmitted by separating and attracting the engine and the power take-off component through the stretching and contracting actions of the electric push rod; the electric push rod is used for accurately controlling the separation and suction time of the clutch, so that the service life of the clutch plate is prolonged.
