Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0018] Please refer to the attached Figure 1-2 description. In this embodiment, a limiting device that is convenient for maintenance and disassembly is provided. The limiting device that is convenient for maintenance and disassembly includes:

[0019] a material distributor, a three-way hopper 1, an electro-hydraulic push rod 2, a belt conveyor 7, a limiting auxiliary installation mechanism, a fixed pulley 3, and a limiting mechanism; the material distributor is arranged above the three-way hopper 1, the discharge port of the material distributor is communicated with the feed port at the upper end of the three-way hopper 1, the electro-hydraulic push rod 2 is fixedly installed on the material distributor, one end of the limiting auxiliary installation mechanism is fixedly connected with the electro-hydraulic push rod 2, the other end of the limiting auxiliary installation mechanism is movably connected with the electro-hydraulic push rod 2, the fixed pulley 3 is fixedly installed on the three-way hopper 1, the limiting mechanism is arranged directly below the fixed pulley 3 and is fixedly connected with the three-way hopper 1, the belt conveyor 7 is arranged directly below the higher discharge port of the three-way hopper 1, and the limiting auxiliary installation mechanism and the limiting mechanism are fixedly connected by a connecting rope.

[0020] The limiting auxiliary installation mechanism includes a first auxiliary table, a limiting ring, a second auxiliary table, and an auxiliary rod. The first auxiliary table is fixedly installed on the hydraulic cylinder part of the electro-hydraulic push rod 2, the limiting ring is fixedly arranged on the first auxiliary table, the second auxiliary table is fixedly installed at the end of the telescopic part of the electro-hydraulic push rod 2, one end of the auxiliary rod is fixedly connected with the second auxiliary table, and the other end of the auxiliary rod passes through the limiting ring and is movably connected along the limiting ring.

[0021] The limiting mechanism includes a counterweight chute 5, a counterweight induction block 6, a first induction limit 8, and a second induction limit 9. The counterweight chute 5 is fixedly installed on the three-way hopper cylinder, the counterweight induction block 6 moves up and down along the counterweight chute 5, the first induction limit 8 is fixedly installed at the upper end of the counterweight chute 5, and the second induction limit 9 is fixedly installed at the lower end of the counterweight chute 5.

[0022] The counterweight induction block 6 and the end of the auxiliary rod close to the second auxiliary table are fixedly connected by a connecting rope.

[0023] A flap 4 is further arranged on the three-way hopper cylinder, and the flap 4 is arranged at the lower end of the fixed pulley 3.

[0024] A fixing rod is arranged at the lower end of the flap 4.

[0025] It further includes a connecting member. One end of the connecting member is fixedly connected to the end of the telescopic part of the electro-hydraulic push rod 2, and the other end of the connecting member is fixedly connected to the fixed rod.
