The present invention will be described in detail with reference to the accompanying drawings and the detailed description.
According to the utility model, a material distributing device capable of automatically adjusting the position is provided, as shown in figures 1, 2 and 3, comprising a blowing device 2, wherein the blowing device 2 is arranged at the tail end of a conveyor belt 1 and is used for blowing gas to the material; the first bin 6 is arranged on a slide rail of the rack 11, connected with the cylinder and used for receiving the good materials; the second bin 7 is arranged on the rack 11 and used for receiving waste materials; the first air cylinder 9 is arranged on the frame and connected with the controller to receive commands of the controller and control the movement of the first bunker 6; the second cylinder 12 is arranged on the frame and connected with the controller to receive the command of the controller and control the movement of the second storage bin 7; the displacement sensor 13 is connected with the controller and is used for collecting and transmitting the position information of the first bin 6 and the second bin 7; and the controller is used for calculating the target position of the bin and controlling the cylinder to move the bin to the target position.
The first bin 6 and the second bin 7 are arranged on the rack 11 and can slide, and the bottom surfaces of the first bin and the second bin are at a certain height from the conveyor belt, so that the landing time of materials is increased, and the horizontal flight time and the flight distance of the blown materials in the air are increased.
The blowing device 2 is arranged at the tail end of the conveyor belt 1 and comprises nozzles which are arranged in the direction vertical to the material conveying direction and can be one row or multiple rows. Both the angle and the force of the nozzle can be adjusted and both parameters are collected by the controller for subsequent adjustment.
The particle size of the material on the conveyor belt 1 is pre-screened and relatively uniform, for example, as 10-45mm samples of medium blocks. After the color sorting, the material separating device receives the time for starting the blowing device, so that the waste material is blown to be separated from the good material at the time when the waste material moves to the tail end of the conveyor belt.
The first bin 6 is slidably connected to a guide rail of the frame 11, is connected to a first cylinder 9 arranged on the frame, and can freely move under the telescopic control of the first cylinder 9.
The first cylinder 9 and the controller are electrically connected, such as wired or wireless connection. The controller can be a single chip microcomputer, an arm, a central controller and the like, can calculate the target position of the falling waste materials, sends an instruction with the target position to the first air cylinder 9, and the first air cylinder 9 stretches and retracts according to the instruction of the controller to drive the first storage bin 6 to move to the designated position.
The displacement sensor is used for monitoring and collecting the position information of the first bin 6 and the second bin 7 and sending the information to the controller.
The controller can input signals manually, can also collect signals, and then calculates, and the signals comprise: the speed of the conveyor belt, the particle size of the waste, the pressure of the blowing device, the blowing angle, and the quality of the waste.
When the material reaches the tail end of the conveyor belt machine 1, when the blowing and spraying device does not work, the material is good material, and the material does horizontal parabolic motion and falls into the first bin 6. According to the horizontal parabolic motion formula, the motion tracks of the materials under different granularity and speed parameters can be calculated. Specifically, the initial velocity of the conveyor belt is v, the particle size of the material is 0, and when the material is thrown off the conveyor belt 1, assuming that the tail end of the conveyor belt 1 is zero, by solving a second equation set:
x1=v*t ，
slide rail-conveyor belt vertical distance y1=1/2gt
x2=v*t
y1+1/2d=1/2gt²
The theoretical horizontal displacement x1 when the material granularity is 0 and the falling position x2= v × t +1/2d in the horizontal direction when the material granularity is d can be obtained. The parabolas in both cases are shown as 3, 4 in fig. 1. The first silo 6 is arranged at a position covering the range of x 1-x 2, for example, the center of the first silo 6 is arranged at the centers of x1 and x2, and is used for receiving good materials.
When the separator is used for separating different mineral aggregates, if the granularity of the mineral aggregates is not changed, the position of the first bin does not need to be adjusted, but if the granularity of the mineral aggregates is changed, the position of the first bin can be automatically adjusted according to the granularity of the mineral aggregates without manually moving the first bin.
In the device, the second cylinder 12 receives the command of the controller and controls the second bin 7 to move to a specified position, so that the position of the bin for receiving waste materials can be adjusted at any time according to the speeds of different minerals and conveying belts.
When the blowing device works, the materials are indicated to be waste materials and need to be separated to the second storage bin, after the waste materials are under the action of the pressure of the blowing gas, the parabolic track of the materials is changed and then falls into the second storage bin, and the parabolic track is shown as 5 in figure 1. According to the stress analysis, the movement locus of the waste material under the states of different pressures, different particle sizes and different conveying speeds can be recalculated, and the movement locus is the movement locus of the waste material separated from the good material after the material is sprayed out by the nozzle. Specifically, when the scrap passes through the blowing device, the nozzle applies a force F to the scrap, and the acceleration a = (F-F)/m and the velocity v = at are known from the formula1At this time t1F is friction force and can be 0, wherein a = F/m, and the initial velocity V = Ft of the material to be blown1The initial velocity V1= V sinA in the vertical direction and the initial velocity V2= V cosA in the horizontal direction can be obtained as the angle a between the initial velocity and the transport direction. At the moment, the speed of the conveyor belt is taken as v, and a first equation group is solved under the limit state when the granularity of the material is zero:
V=Ft1/m
v1=V*sinA
v2=V*cosA
vertical displacement y2=1/2 gt-v 1 × t
Horizontal displacement x3= v t + v2 t
The horizontal limit position x3 of the falling waste material is solved, and the second bin is conveyed to the position x3 by the controller controlling the movement of the air cylinder. Such as the center of the second silo at a location x 3.
As shown in fig. 4, the nozzles may be arranged in two rows, which is beneficial to the uniformity of the material stress.
In one embodiment, if the positions of the first and second silos overlap, the position of the second silo is set to x3, spaced a distance from the first silo, then F is recalculated according to the above 5 formulas, using x3 as the known condition, and then the controller controls the cylinder to move the second silo to the x3 position, sending the parameter F to the blowing device, and commanding the blowing device to blow at the magnitude of the force F.
In another embodiment, if the positions of the first bin and the second bin overlap, the two bins are positioned x3, spaced a distance from the first bin, then the angle of injection is recalculated according to the above 5 formulas, using x3 as the known condition, then the controller controls the cylinder to move the second bin to the x3 position, sending the parameter angle of injection to the blowing device, and commanding the blowing device to blow at the new angle of injection.
When mineral aggregate is identified, the nozzles can be selected to spray good material or waste material, and accordingly, the first storage bin and the second storage bin can be used for good material or waste material.
Through the utility model discloses, can artifical set parameter or automatic acquisition parameter, then carry out the adjustment of first feed bin 6 and second feed bin 7 and/or blowing power, angle etc for the receipt of waste material is automatic, potential safety hazard when reducing the equipment debugging, and the rate of accuracy of receiving has been improved.
Although illustrative embodiments of the invention have been described above to facilitate the understanding of the invention by those skilled in the art, it should be understood that the invention is not limited to the scope of the embodiments, and that various changes may be made apparent to those skilled in the art without departing from the spirit and scope of the invention as defined and defined in the appended claims.
