All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention will be described in detail with reference to the drawings and detailed description.
According to the invention, a distributing device capable of automatically adjusting the position is provided, as shown in figures 1, 2 and 3, and comprises 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 materials; the first storage bin 6 is arranged on a sliding rail of the frame 11, is connected with the air cylinder and is used for receiving good materials; the second bin 7 is also arranged on a sliding rail of the frame 11 and is used for receiving waste materials; the first air cylinder 9 is arranged on the frame and connected with the controller to receive the command of the controller and control the movement of the first stock bin 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 stock bin 7; the displacement sensor 13 is connected with the controller and is used for collecting and transmitting the position information of the first storage bin 6 and the second storage bin 7; and the controller is used for calculating the target position of the bin and controlling the air cylinder to move the bin to the target position.
The first bin 6 and the second bin 7 are arranged on the frame 11 and can slide, and the bottom surface of the first bin 6 and the second bin is at a certain height from the conveyor belt, so that the time for landing the 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, and the nozzles are arranged along the direction perpendicular to the conveying direction of the materials and can be in one row or multiple rows. The blowing angle and force of the nozzle can be adjusted, and the two parameters can be collected by the controller for subsequent adjustment.
The particle size of the material on the conveyor belt 1 is pre-screened, relatively uniform, e.g. 10-45mm each, for example, for a sample of a medium size. After the color selection, the material separating device receives the time for starting the blowing device, so that the waste material is blown to separate the waste material from the good material when the waste material moves to the tail end of the conveyor belt.
The first stock bin 6 is slidably connected to a guide rail of the frame 11, is connected to a first cylinder 9 provided on the frame, and can move freely under the telescopic control of the first cylinder 9.
The first cylinder 9 is electrically connected to the controller, such as a wired or wireless connection. The controller can be a singlechip, arm, a central controller and the like, can calculate the target position of the falling waste, and sends an instruction with the target position to the first air cylinder 9, and the first air cylinder 9 stretches and contracts 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 be through artifical input signal, also can gather the signal, then calculate, and the signal includes: the speed of the conveyor belt, the particle size of the waste, the pressure of the blowing device, the blowing angle, the quality of the waste.
When the material reaches the tail end of the conveyor belt 1, the blowing device is not in operation, the material is indicated to be good, and the material is horizontally thrown to fall into the first bin 6. According to the horizontal parabolic motion formula, the material motion trail under different granularity and speed parameters can be calculated and obtained. Specifically, the initial speed of the conveyor belt is v, the granularity of the material is 0, when the material is thrown from the conveyor belt 1, the tail end of the conveyor belt 1 is assumed to be zero point, and the second equation set is solved:
x1=v*t ，
vertical distance between slide rail and conveyor belt y1=1/2 gt
x2=v*t
y1+1/2d=1/2gt²
The theoretical horizontal displacement x1 of the material with the granularity of 0 and the falling position x2 = v x t+1/2d of the material 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 bin 6 is arranged at a position covering the range of x1 to x2, for example, the center of the first bin 6 is arranged at the center of x1 and x2, so as to receive good materials.
When the separation device is used for separating different mineral aggregates, the position of the first storage bin is not required to be adjusted if the granularity of the mineral aggregate is unchanged, but the position of the first storage bin can be automatically adjusted according to the granularity of the mineral aggregate without manually moving the first storage bin if the granularity of the mineral aggregate is changed.
In the device, the second cylinder 12 receives the command of the controller and controls the second bin 7 to move to the designated position, so that the position of the bin for receiving the waste can be adjusted at any time according to different minerals, the speed of the conveyor belt and the like.
When the blowing device works, the material is described as waste material, the waste material needs to be separated into a second storage bin, and after the waste material is subjected to the action of the blowing pressure, the parabolic track of the material changes and then falls into the second storage bin, wherein the parabolic track is shown as 5 in fig. 1. According to the stress analysis, the motion trail of the waste materials under different pressures, different granularities and different conveying speeds can be recalculated, wherein the motion trail is the motion trail of the waste materials separated from the good materials after the materials are sprayed out by the nozzle. Specifically, when the waste material passes through the blowing device, the nozzle applies an acting force F to the waste material, the acceleration a= (F-F)/m, the velocity v=at 1 can be known according to a formula, at this moment, t 1 is the blowing time of the blowing device, F is the friction force, 0 can be taken, at this moment, a=f/m, the initial velocity v=ft 1/m obtained by the material to be blown, the angle a between the initial velocity and the conveying direction, the initial velocity v1=v sinA in the vertical direction, and the initial velocity v2=v cosA in the horizontal direction can be obtained. At the moment, under the limit state that the speed of the conveyor belt is v and the granularity of the materials is zero, solving a first equation set:
V=Ft1/m
v1=V*sinA
v2=V*cosA
vertical displacement y2=1/2 gt) v 1t
Horizontal displacement x3 =v×t+ v2 t
And (3) solving the horizontal limit position x3 of the falling waste, and controlling the movement of the air cylinder through the controller to send the second storage bin to the position x 3. Such as the center of the second silo at a location x 3.
In one embodiment, if the positions of the first and second bins overlap, the position of the second bin is set to x3, spaced a distance from the first bin, then F is recalculated according to the first set of equations above, taking x3 as a known condition, then the controller controls the cylinder to move the second bin to the x3 position, sends the parameter F to the blowing device, and instructs the blowing device to blow with the magnitude of force F.
In another embodiment, if the positions of the first bin and the second bin overlap, the positions of the two bins are set to x3, which is spaced apart from the first bin by a certain distance, then the injection angle is recalculated according to the above first system of equations, taking x3 as a known condition, then the controller controls the cylinder to move the second bin to the x3 position, sends the parameter injection angle to the injection device, and instructs the injection device to perform injection at the new injection angle.
In the process of identifying mineral aggregate, a nozzle can be selected to spray aggregate or waste material, and accordingly, the first bin and the second bin can be good aggregate or waste material.
According to the invention, parameters can be set manually or acquired automatically, and then the first bin 6 and the second bin 7 and/or the injection force, the angle and the like are adjusted, so that the receiving of the waste materials is automated, the potential safety hazard during equipment debugging is reduced, and the receiving accuracy is improved.
While the foregoing describes illustrative embodiments of the present invention to facilitate an understanding of the present invention by those skilled in the art, it should be understood that the present invention is not limited to the scope of the embodiments, but is to be construed as protected by the accompanying claims insofar as various changes are within the spirit and scope of the present invention as defined and defined by the appended claims.
