Embodiment 1
[0035] A new auxiliary feeding device for ore crushing, such as Figure 1-3 As shown, a new auxiliary feeding device for ore crushing includes a feeding device base 1, a swing hydraulic cylinder 2, an arc rod 3 and a connecting bottom plate 4, and a swing hydraulic cylinder is installed on the side of the feeding device base 1 2. The connecting base plate 4 is connected to the piston rod of the swing hydraulic cylinder 2, and an arc-shaped rod member 3 is connected between the top of the connecting base plate 4 and the base 1 of the unloading device. It is characterized in that it also includes a telescopic hydraulic cylinder 5, a telescopic body And the exciter 8, the telescopic hydraulic cylinder 5 is installed in the middle of the bottom of the connecting base plate 4, and the expansion body is arranged between the two sides of the bottom of the connecting base plate 4. The expansion body is composed of a cross bar 6 and a support bar 7, and the cross bar 6 is hinged on Con...
Embodiment 2
[0038] On the basis of Example 1, such as Figure 5-6 As shown, the body bending assembly is also included. The body bending assembly includes a hoist 13, a pulley 14, a displacement rod 15 and a steel wire rope 16. Two hoisting machines 13 and two pulleys 14 are installed above the base 1. On the hoisting machine 13 A steel wire rope 16 is wound around, and the tail end of the steel wire rope 16 walks around the pulley 14 and is connected with the telescopic body, and the middle part of the telescopic body is provided with a shifting rod 15 .
[0039] When the swing hydraulic cylinder 2 has been stretched to the maximum position, the rotation angle of the body is small, and the working range of the exciter 8 is limited. The body is bent, which greatly increases the working range of the vibrator 8 .
[0040] Such as Figure 5-6 As shown, the displacement rod 15 includes a gear 17, a rack 18 and a small motor 19, a small motor 19 is connected between the upper and lower cross...
Embodiment 3
[0043] On the basis of Example 1, such as Figure 7-8 As shown, a protective assembly is also included, and the protective assembly includes a fixed seat 20, an elastic protective sleeve 21, a conical cylinder 22, a lower connector 23 and an upper connector 24, and the bottom of the connection base plate 4 is equipped with a fixed seat 20. There is a through hole in the middle part, and the telescopic hydraulic cylinder 5 runs through the fixed seat 20. The bottom of the fixed seat 20 is connected with an elastic protective cover 21, and the side of the elastic protective cover 21 has an opening. The steel wire rope 16 passes through the opening of the elastic protective cover 21, and the elastic protective cover 21 Covered on the outside of the telescopic body, the outside of the exciter 8 is connected with a conical cylinder 22 , the top of the conical cylinder 22 is provided with a lower connector 23 , and the bottom of the elastic protective sleeve 21 is connected with an u...
