This utility model discloses a braking system for an excavator loader, comprising a foot brake valve. The P port of the foot brake valve is connected to an accumulator and the outlet of a charging valve. The T port of the foot brake valve is connected to an oil tank. The A port of the foot brake valve is connected to the P1 port of a solenoid directional valve. The T1 port of the solenoid directional valve is also connected to the oil tank. The A1 and B1 ports of the solenoid directional valve are connected to the right rear axle brake and the left rear axle brake, respectively, via a right brake light switch and a left brake light switch. The control terminals a1 and b1 of the solenoid directional valve are connected to one electrode of a power supply. The other electrode of the power supply is connected to terminal n of a three-position switch. Terminals e1 and e2 of the three-position switch are connected to the control terminals a2 and b2 of the solenoid directional valve, respectively. This utility model features low cost, simple mechanism, saves interior space in the cab, is easy to operate, and is convenient and flexible in layout.

In the utility model, the position of front axle and rear axle can be detected by the detection mechanism, so that the front axle and rear axle are ensured to be in the state of returning to normal, and the fixed mechanism is further arranged to tighten the threaded connection, to prevent the loosening and falling of the thread.

This invention discloses a bidirectional braking system for a backhoe loader, comprising a gearbox, a loading brake valve, and a brake. The gearbox supplies oil to the loading brake valve and the digging brake valve. Both brake valves are connected to the brake via a selector valve. The backhoe loader has control devices at its two different working ends for controlling whether the two brake valves are open. When the backhoe loader is in loading operation, the selector valve opens the loading brake valve and the brake; when the backhoe loader is in digging operation, the selector valve opens the digging brake valve and the brake. This device enables bidirectional braking of the backhoe loader during both digging and loading operations.

The funnel attachment for a heavy machinery bucket includes a funnel and one or more hydraulic pistons. The funnel may be pivotably coupled to a bucket of a loader. The one or more hydraulic pistons may pivot the funnel between a funnel lifted position and a funnel lowered position. The funnel may be pivoted to the funnel lifted position in order to fill the bucket with material. The funnel may be pivoted to the funnel lowered position to empty the bucket through the funnel. As non-limiting examples, the loader may include a backhoe loader, a front loader, a wheel loader, a skid steer loader, or a track loader and the material may comprise sand, gravel, or soil.
