[0034] ​The vibrating distributing device comprises a feeding trough 1 and a vibrating motor, the vibrating motor is installed on the outer side of the feeding trough 1, the feeding trough 1 has a front side opening and an upper side opening, the front side opening of the feeding trough 1 is connected with the subsequent device (generally a multi-channel chute after the sorting machine) as the discharge end, the feeding trough 1 is connected with the external equipment frame body through the suspension connection assembly, the discharge port of the material bin device extends into the upper side opening of the feeding trough 1 and is located at the rear position in the inner cavity of the feeding trough 1. In the embodiment, for the convenience of description, the direction in which the material exits from the feeding trough 1 is the front side, and the direction opposite to the material exiting from the feeding trough 1, that is, the direction of incoming material is the rear side. The vibrating motor in the embodiment adopts a commercially available product, and the action is controlled by an external controller. In the vibrating distributing device in the embodiment, the resonance principle of mechanical vibration is used, and the double mass works in the low critical near resonance state, so that the material flow can be changed and opened and closed instantaneously, and the feeding amount has high precision. The control equipment of the vibrating motor can adopt a silicon-controlled half-wave rectifier circuit, so that the feeding amount can be conveniently and steplessly adjusted by adjusting the opening angle of the silicon-controlled silicon during use, and centralized control and automatic control of the production process can be realized. Through the setting of the vibrating motor, the feeding trough 1 can be provided with vibrating force, so that the material uniformly moves out of the feeding trough 1, the subsequent sorting space is fully utilized, and the materials do not adhere to each other but form a single material flow, so as to ensure the accuracy of subsequent identification and calculation.

[0035] Specifically, the inner cavity bottom surface of the feeding trough 1 in the embodiment gradually inclines downward from rear to front. In the embodiment, it is calculated that the angle between the inner cavity bottom surface of the feeding trough 1 and the horizontal plane is 0-9°, which is the best adaptive angle.

[0036] Specifically, as shown in Figure 1 and Figure 3As shown, the middle part of the inner cavity bottom surface of the feeding trough 1 in the embodiment is provided with a distribution guide plate 2, and two distribution guide plates 2 are arranged on the inner cavity bottom surface of the feeding trough 1 in a “eight” shape. The inner side of the “eight” shape formed by the two distribution guide plates 2 forms a material channel A 001 parallel to the front-rear direction of the feeding trough 1, and the left and right sides of the “eight” shape formed by the two distribution guide plates 2 respectively form material channels B 002 parallel to the front-rear direction of the feeding trough 1. The front side opening of the material channel A 001 is larger than the rear side opening of the material channel A 001, and the front side opening of each material channel B 002 is smaller than the rear side opening of the material channel B 002.

[0044] Each spring limiting seat 16 is divided into a mounting plate part 1601 and a limiting frame part 1602 which are connected together by bolts or welding, the mounting plate part 1601 of each spring limiting seat 16 is located at the lower side of the limiting frame part 1602 of the spring limiting seat 16, the mounting plate part 1601 of one spring limiting seat 16 is fixedly connected to each of the left and right side surfaces of the vibration motor protective cover 9, the limiting frame part 1602 of each spring limiting seat 16 is correspondingly provided with the lower end of one suspension hanger 15, the upper end of each suspension hanger 15 is located at the outer side of the limiting frame part 1602 of the corresponding spring limiting seat 16 and is fixedly connected to the external equipment rack, the lower end of each suspension hanger 15 which is located at the inner side of the limiting frame part 1602 of the corresponding spring limiting seat 16 is threadedly connected to a fastener, the lower end of each suspension hanger 15 which is located at the inner side of the limiting frame part 1602 of the corresponding spring limiting seat 16 is further sleeved with a spring B17, the upper end of each spring B17 abuts against the inner side top surface of the limiting frame part 1602 of the corresponding spring limiting seat 16, and the lower end of each spring B17 abuts against the adjacent fastener. In the embodiment, the fastener can be a combination of a nut and a washer, or other existing setting modes, and by replacing the suspension hangers 15 with different lengths, the amplitude range of the vibration of the feeding trough 1 can be adjusted.

[0045] Through the setting of the suspension connecting assembly, the feeding trough 1 has the ability to swing around the axial center line of the swing rotation shaft 10, so as to better adapt to the vibration provided by the vibration motor and freely vibrate within a limited range. In the embodiment, the spring A12 and the spring B17 are both rubber springs. Through the setting of the spring structures at various positions, the partial stress between the components can be effectively eliminated, the feeding trough 1 can freely vibrate within a limited range, and the feeding is smoother. In the embodiment, each suspension hanger 15 is arranged outwardly and upwardly by 10°, which can reduce the lateral swing of the feeding trough 1 and make the falling material continuously and evenly spread.

[0046] Working principle:

[0047] In normal operation, the linear falling material is gathered into the bin device through the belt conveyor, the vibration motor provides vibration power, and the feeding trough 1 vibrates.

After the material is output from the feeding trough 1, it uniformly passes through the multi-channel chute and detection components of the subsequent sorting machine, is detected, and then is separated into concentrate and tailings by the sorting components of the sorting machine and is output to the subsequent process through different conveyors.
