Description

Technical Field

[0001] The invention relates to a hopper vibration type material discharging device, in particular to a hopper vibration type material discharging device for aeolian sand and loess. Background Art

[0002] In the coal mine paste filling system, in order to reduce the cost of coal mine backfill mining, different filling materials are used according to local conditions. In the northwest desert area of ​​my country, local unique aeolian sand and loess are generally used as raw materials for paste filling. When the temperature is low in the rainy season or winter, the moisture content of aeolian sand and loess is relatively high; aeolian sand and loess with a humidity greater than 5% are easy to compact, and it is difficult to discharge in the screening hopper, causing difficulties in feeding; at the same time, the vegetation growing in the northwest desert area of ​​my country has a well-developed root system, which is mixed in the mined loess and aeolian sand. The root system of the vegetation affects the screening and feeding, and also affects the safety of the filling pipeline.

[0003] When the wind-blown sand and loess are in the rainy season or the low temperature in winter, the environmental humidity is greater than 5%, which is easy to cause the wind-blown sand and loess to stick together and compact. The wind-blown sand and loess screening devices sold on the market generally use a feeding vibration device with an external vibrating motor. The screening device using an external vibrating motor makes the material more likely to compact, and cannot achieve continuous screening and feeding of wind-blown sand and loess raw materials under the above environment. At present, there is no vibration device on the market that can meet the screening and feeding of wind-blown sand and loess.

[0004] This requires a screening device that can not only remove impurities in loess and aeolian sand, but also smoothly screen the material. The screening device needs to have a simple structure, be strong and durable, be easy to operate, and be easy to disassemble and maintain. Summary of the invention

[0005] The purpose of the present invention is to provide a vibrating feeding device for aeolian sand and loess hoppers, so as to solve the problem of smooth feeding when the humidity of aeolian sand and loess is greater than 5% and the temperature is low, and to avoid the problem of manual cleaning and insufficient material supply, which affects the batching.

[0006] The objective of the present invention is achieved in that: a vibrating material discharging device comprises: a receiving hopper, a vibrating grate, a vibrating rod, a spring bracket, a spring, a mounting plate, a rapping device, a vibrating motor seat and a vibrating motor; the upper end of the vibrating rod is connected with a mounting plate or a vibrating motor seat, a vibrating motor is connected to the vibrating motor seat, and the mounting plate is used to fix the vibrating material discharging device; the lower end of the vibrating rod is connected with a vibrating grate, and a rapping device is connected to the middle position of the bottom surface of the vibrating grate; a spring bracket is connected to the inner wall at the upper end of the receiving hopper; the vibrating rod below the mounting plate is sleeved in the spring, the lower end of the spring sits on the spring bracket, and the vibrating rod can slide in the spring.

[0007] The rapping device comprises: oblique side rods, a bottom cross rod, a main rod and a rapping mounting plate; a rapping mounting plate is connected to the upper end of the main rod, and the rapping mounting plate is used for connecting the vibrating grate; a bottom cross rod is connected to the bottom end of the main rod, and the main rod is arranged with multiple layers of oblique side rods from top to bottom, and the oblique side rods of each layer are symmetrically installed, and the oblique side rods of every two layers are distributed at 90°.

[0008] The receiving hopper is a quadrilateral funnel with a taper and a smooth inner wall; the lower outlet is connected to a belt feeder, and the upper opening is larger than the lower outlet, so that the loader can load the material conveniently.

[0009] There are four spring brackets connected to the four sides of the inner wall of the receiving hopper by bolts. A guide sleeve of a vibration pull rod is arranged on the spring bracket to support the vibration pull rod. When the vibration motor vibrates, the vibration pull rod moves up and down along the guide sleeve.

[0010] The vibrating grate is square, has hinge holes on four sides for hinge connection with the vibrating pull rods, and is connected to the vibrating pull rods through pins; the vibrating grate is located in the receiving hopper, and the height of the vibrating grate in the receiving hopper is determined by four vibrating pull rods.

[0011] The vibrating pull rod is a high-strength thick-walled steel pipe with a bend. The upper part is an upright section, the end of which is connected to the vibration motor base, and the lower part is a bent section. The bending angle is the same as the taper of the receiving hopper; the lower part of the bent section is connected to the vibrating grate through a pin shaft.

[0012] Beneficial effect: Due to the adoption of the above scheme, the exciting force of the vibration motor acts on the vibration rod, and the vibration grate net is vibrated up and down through the spring sleeved on the vibration rod, and the lower vibrating device also moves up and down with the vibration grate net, so that the bonded and compacted aeolian sand and loess are vibrated and crushed or forced to be crushed. The receiving hopper has a certain angle and a smooth interior. The grate holes of the grate net neither affect the discharge of materials nor have a certain filtering effect on the debris in the materials. When the humidity of aeolian sand and loess is less than 5%, the material can be discharged normally. When the humidity is too high and the temperature is low, the discharge will be difficult. The vibration device is remotely started to make the aeolian sand and loess flow smoothly downward from the receiving hopper. The vibration motor is controlled by the controller. There is a remote control device in the controller. The start and stop and frequency adjustment of the vibration motor can be remotely controlled.

[0013] The grate is vibrated by a variable frequency vibration motor, and the lower vibrating device moves up and down with the grate, so that the material at the bottom of the hopper can be discharged smoothly; when it is difficult to discharge loess and aeolian sand, the vibration motor is turned on, and the vibration motor drives the vibration rod and the vibration grate to vibrate, thereby ensuring the outflow of materials; when the feeder coordinated with the lower part of the hopper vibration discharge device stops running or the material is discharged smoothly, the variable frequency vibration motor is turned off to reduce the operating cost; the start, stop and vibration frequency of the variable frequency vibration motor can be adjusted through remote operation, which meets the paste filling ingredients and provides a strong guarantee for the paste pipeline transportation and paste filling system.

[0014] The hopper vibration unloading device of the present invention realizes the smooth unloading of loess and aeolian sand in the hopper and the filtering of foreign objects such as tree roots. The vibration device and operation of the vibration frequency adjustment by the variable frequency vibration motor are simple in structure, durable, easy to operate, convenient to disassemble and maintain, filling the gap in the industry, etc., and solves the problem of smooth unloading of aeolian sand and loess when the humidity is greater than 5% and the temperature is low, avoiding the problem of manual cleaning and insufficient material supply, which affects the batching. The purpose of the present invention is achieved.

[0015] 1. The use of a vibrating feeding device ensures smooth feeding when the humidity of aeolian sand and loess is greater than 5% and the temperature is low, avoiding the problem of manual cleaning and insufficient material supply that affects the batching.

[0016] 2. A vibrating feeding device is used. The vibration of the vibrating grate makes the feeding smooth. At the same time, it can filter out the debris in the material, preventing tree roots and other debris from entering the filling system and causing accidents such as pipe blockage.

[0017] 3. A vibrating feeding device is used. When the screening and feeding is abnormal, the vibration motor is turned on, and the frequency of the vibration motor is adjusted according to the on-site conditions to improve the efficiency of vibration screening. When the screening and feeding is normal, the vibration motor is turned off, which greatly reduces the operating cost of the filling system batching workshop.

[0018] Advantages: The invention has the advantages of simple structure, convenient processing, safety and reliability, and is easy to operate and maintain when installed in the hopper.
