In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

The third spur gear 407 is in contact with the top of the first spur gear 8. One end of the third spur gear 407 is fixedly connected to a reciprocating screw rod 408, and the outer wall of the reciprocating screw rod 408 is connected to a movable block 409, which is slidably connected to the inside of the lubrication seat 401 and is located at the bottom end of the baffle 403.

At the same time, the movable block 409 moves to drive the extrusion block 414 to contact the inner wall of the movable groove 410, and the extrusion block 414 is displaced by force. The displacement of the extrusion block 414 pushes the clamping block 412 to move out of the clamping groove 411, canceling the push on the baffle 403. The baffle 403 is reset by the elastic force of the first spring 404, and the oil dripping hole 405 is separated from the through hole 406, so that only a small amount of lubricating oil drips through the oil dripping hole 405 each time, and the lubricating oil drips onto the gear transmission group 10, which is convenient for automatically adding lubricating oil to the gears during the movement of the loader to reduce the wear on the gears.
