All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," "third," and "fourth" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Unless expressly stated or limited otherwise, the terms "connected" and "attached" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, or an integral connection; can be directly connected or connected through an intermediate medium; either mechanically or electrically. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.
The specific structure is shown in fig. 1-6.
The material transporting and distributing device provided by the present embodiment, mainly referring to fig. 1, includes a dividing member 100 and a throwing mechanism;
the throwing mechanism can throw the materials out to form a material flow 200, the direction of the horizontal component of the movement direction of the materials is a first direction, and the dividing piece 100 is arranged at the downstream of the throwing mechanism along the direction of the movement track of the materials;
the throwing speed of the material is adjustable along the first direction;
the divider 100 is capable of cutting the separator material flow 200 in different proportions during adjustment of the material ejection speed.
With the above structure, the dividing member 100 is disposed downstream of the throwing mechanism in the direction of the material moving track, when the material is thrown out by the throwing mechanism, the material forms the material flow 200 and moves along the moving track, and when the material flow 200 moves to the position of the dividing member 100, the dividing member 100 can cut the material flow 200 and separate the material flow 200. According to different working condition requirements, when the proportion of the material flow 200 cut and separated by the dividing piece 100 needs to be changed, the throwing speed of the material is adjusted, the motion track of the material is controlled to move within the maximum span range of the dividing piece 100, the position where the material flow 200 intersects with the dividing piece 100 is changed, and therefore the proportion of the material flow 200 cut by the dividing piece 100 is changed. By changing the division ratio of the material flow 200, the materials can be distributed in different ratios, and the technical problem that material distribution equipment in the prior art cannot meet the requirement of material transformation ratio distribution is solved.
It should be noted that the partition 100 provided in the present embodiment has significant advantages over the gate or flap in the prior art: firstly, it is known through experiments that the material can only be distributed in a fully open or fully closed mode by using the gate plate structure, and if other proportions are taken, the gate plate is locked at a certain opening degree, and under the impact of the material flow 200, the gate plate is very easily impacted and deformed by the material flow, so that irreversible damage occurs at the equipment. When the material is distributed by utilizing the turning plate, the turning plate is in transmission connection with the driving piece, under the impact of the material flow 200, the structure of the turning plate is easily damaged, and the driving piece is also easily damaged under the impact, so that irreversible loss is caused. And the piece 100 of cutting apart in this embodiment is fixed connection structure with the casing, and is different with the flashboard with turn over the adjustable structure of board under the drive of driving piece, and fixed connection structure can stably undertake the impact of material flow 200, has avoided the flashboard among the prior art or has turned over the board and receive the structural deformation that the material strikes and appear, leads to material transportation distributor to appear irreversible damage problem, consequently, the piece 100 of cutting apart in this embodiment has more stable, the longer advantage of life-span at the during operation.
Secondly, referring mainly to fig. 4-6, the dividing member 100 of the present embodiment divides the material flow 200 to distribute the material, and the dividing portion of the dividing member 100 is disposed at an angle to the first direction, so that the dividing portion can divide the material flow 200 in proportion along the width direction of the conveyor belt. In this case, even if the material flow 200 is a single-layer material flow 240 having a large monomer volume, the single-layer material flow 240 can be divided proportionally by the dividing member 100 as long as a plurality of monomers are secured in the width direction of the conveyor belt. In the structure of the turning plate 010 in the prior art, no matter how the angle of the structure of the turning plate 010 is adjusted, the single-layer material flow 240 cannot be divided proportionally. Moreover, the partition member 100 in this embodiment also avoids the problem that the single material flow 240 has a large volume, which causes a large impact on the flap 010 or the gate, and thus damages the flap 010, the gate and the driving device thereof.
Thirdly, the corresponding driving device is often needed to be configured for the structure of the turning plate 010 or the gate plate, the occupied space of the whole device is large, the occupied space of the partition piece 100 in the embodiment is small, various working condition requirements can be met, and the adaptability is strong.
The material transportation and distribution device is used for distributing materials in a preset proportion in an adjustable mode in the process of transporting the materials, wherein the throwing mechanism conveys the materials which are not distributed, and the input end of the material transportation and distribution device in the process of transporting the materials can be seen. This material transportation distributor can directly carry out material distribution in the material transportation process, realizes the dynamic allocation process, compares with the process of transporting again after distributing static material alone, has directly saved the material transport time, has promoted material transport efficiency.
In an alternative solution of this embodiment, referring mainly to fig. 2, the dividing member 100 is in a shape of a linear plate, the dividing member 100 has a linear dividing portion 110 for cutting and separating the material flow 200, and the extending direction of the linear plate-shaped dividing member 100 is arranged at an obtuse angle or an acute angle with respect to the first direction; that is, the included angle between the linear dividing portion 110 and the first direction is an angle other than zero angle and an angle other than a flat angle, so that when the material flow 200 moves to the position of the dividing member 100, the linear dividing portion 110 is arranged at a right angle to the material flow 200, and the cutting ratio of the linear dividing portion 110 to the material flow 200 cannot be changed. It is also prevented that the linear dividing portion 110 is disposed in parallel with the material flow 200 when the material flow 200 moves to the position of the dividing member 100, so that the linear dividing portion 110 cannot effectively divide the material flow 200.
Specifically, the divider 100 has a straight divider 110, and when the material flow 200 moves to the position of the divider 100, the straight divider 110 intersects the material flow 200, and the straight divider 110 divides and separates the material flow 200.
Preferably, the linear dividing portion 110 is disposed at an angle to the first direction, and when the material distribution ratio needs to be adjusted, the movement locus of the material is adjusted to move in the first direction, so that the intersection position of the movement locus of the material and the linear dividing portion 110 is changed, thereby changing the position where the linear dividing portion 110 cuts the material flow 200, and thus changing the ratio where the linear dividing portion 110 cuts the separated material flow 200. When the movement locus of the material intersects the midpoint position of the linear divider 110, the material flow 200 is divided at a 1:1 ratio. When the motion trajectory of the material moves beyond the maximum span range of the linear divider 110, the material flow 200 is not divided by the linear divider 110.
In addition, when the material distribution ratio needs to be adjusted, the dividing member 100 may be moved in the first direction, so that the movement locus of the material is displaced relative to the dividing member 100, thereby changing the position where the linear dividing portion 110 cuts the material flow 200, and changing the ratio of the linear dividing portion 110 cutting the separated material flow 200.
In an alternative embodiment of the present invention, referring mainly to fig. 3, the dividing member 100 is in a bent plate shape, the dividing member 100 has a bent dividing portion 120, and the motion track of the material moves relative to the dividing member 100, so that the bent dividing portion 120 changes the cutting ratio of the material flow 200.
Specifically, the bending type dividing part 120 includes a bending type and a curved type, the bending type dividing part 120 of the bending type has a plurality of straight dividing arms 121, the straight dividing arms 121 are connected in sequence, two adjacent straight dividing arms 121 are arranged at an angle, each straight dividing arm 121 is arranged at an angle with the first direction, and each straight dividing arm 121 can cut the material flow 200 when the material flow 200 moves to the position of the dividing piece 100. Two adjacent straight dividing arms 121 form a V-shape, and preferably, the angular bisectors of the included angles of the V-shaped structures are arranged along the first direction. Along the direction from the opening end of the V-shaped structure to the included angle end of the V-shaped structure, the material flow 200 is closer to the included angle between two adjacent straight line dividing arms 121, the proportion of the materials divided between the two straight line dividing arms 121 to the material flow 200 is smaller, and conversely, the proportion of the materials divided between the two straight line dividing arms 121 to the material flow 200 is larger as the material flow 200 is farther away from the included angle between two adjacent straight line dividing arms 121, therefore, the distance of the included angle between the material flow 200 and the adjacent straight line dividing arms 121 can be adjusted by adjusting the motion track of the materials along the first direction, and the proportion of the material flow 200 cut by the two adjacent straight line dividing arms 121 is controlled. The cross-sectional profile of the curved bending-type dividing part 120 is curved, and the straight dividing arm 121 of the bending-type dividing part 120 can be regarded as a dividing arm with a certain radian, and the dividing principle is not described in detail.
Preferably, when the material distribution ratio needs to be adjusted, the motion trajectory of the material is adjusted in the first direction, so that the intersection position of the motion trajectory of the material and the bending type dividing part 120 is moved in the first direction, thereby changing the intersection position of the bending type dividing part 120 and the material flow 200, and thus changing the ratio of the bending type dividing part 120 to cut and separate the material flow 200.
When the material distribution ratio needs to be adjusted, the dividing piece 100 may be moved in the first direction to change the intersection position of the bending type dividing portion 120 and the material flow 200, so that the ratio of the bending type dividing portion 120 cutting the separated material flow 200 is changed.
It should be noted that, according to the requirement of the actual working condition, the dividing element 100 may be a dividing element 100 in a bent plate shape or a dividing element 100 in a straight plate shape.
In an optional technical scheme of this embodiment, referring mainly to fig. 1, the throwing mechanism is an adjustable-speed throwing mechanism, and the movement trajectory of the material can be adjusted in the first direction by adjusting the throwing speed of the throwing mechanism.
Preferably, the movement track of the material is changed by adjusting the throwing speed of the throwing mechanism. And reducing the throwing speed of the throwing mechanism, so that the motion track of the material is close to one end, close to the throwing mechanism, of the partition piece 100, the proportion of the material flow 200 of one side, facing the throwing mechanism, of the partition piece 100 is gradually increased, the proportion of the material flow 200 of one side, away from the throwing mechanism, of the partition piece 100 is gradually decreased, and when the motion track of the material is overlapped with one end, close to the throwing mechanism, of the partition piece 100, all the material flow 200 flows to one side, facing the throwing mechanism, of the partition piece 100. And raising the throwing speed of the throwing mechanism to enable the motion trail of the material to be close to one end of the partition piece 100 departing from the throwing mechanism, the proportion of the material flow 200 on one side of the partition piece 100 departing from the throwing mechanism is gradually increased, the proportion of the material flow 200 on one side of the partition piece 100 facing the throwing mechanism is gradually decreased, and when the motion trail of the material is overlapped with one end of the partition piece 100 departing from the throwing mechanism, all the material flow 200 flows to one side of the partition piece 100 departing from the throwing mechanism.
In addition, the throwing speed of the throwing mechanism can be fixed, meanwhile, the distance between the throwing mechanism and the dividing piece 100 is adjusted along the first direction to achieve adjustment of the motion track of the material, at the moment, in a coordinate taking the ground as a reference system, any position point in the motion track of the material is changed relative to that before adjustment, therefore, the motion track of the material is changed relative to the dividing piece, and the dividing piece 100 can cut and separate the material flow 200 according to different proportions.
In addition, the adjustment of the movement locus of the material can be realized by simultaneously adopting two modes of adjusting the throwing speed of the throwing mechanism and adjusting the distance between the throwing mechanism and the dividing piece 100, so that the dividing piece 100 can cut the separated material flow 200 according to different proportions. The advantage of adopting this kind of mode is, can enlarge the adjustable range of material motion trail, and two kinds of modes homoenergetic enough adjust the material motion trail for it is more convenient to the regulation of material motion trail.
In addition, the throwing speed value of the fixed throwing mechanism can be adopted at the same time, and the throwing angle of the throwing mechanism is changed, so that the speed component of the material along the first direction is changed, the movement track of the material is adjusted, and the cutting piece 100 can cut and separate the material flow 200 according to different proportions.
In an alternative embodiment of this embodiment, referring mainly to fig. 1, the throwing mechanism is a belt conveyor 300.
Preferably, the material is conveyed and ejected by the belt conveyor 300, and the belt conveyor 300 is used for facilitating the material to be spread evenly on the material conveying belt when the material is conveyed, so that the material can form an even material flow 200 after being ejected, and the material flow 200 can be conveniently divided by the dividing member 100 in a precise proportion.
Preferably, a servo motor is adopted to drive the driving wheel of the belt conveyor 300 so as to realize the accurate control of the conveying speed of the belt conveyor 300, so as to ensure that the initial speed of the material during the inclined throwing motion is accurate, and further ensure the accurate motion track of the material.
Preferably, the conveyor belt of the belt conveyor 300 is inclined from bottom to top, so that the material has a horizontal initial velocity and an upward vertical initial velocity at the moment of leaving the belt conveyor 300, thereby making the material make an inclined throwing motion under the action of gravity.
In addition, the conveyor belt of the belt conveyor 300 may be disposed horizontally or inclined from the top to the bottom.
In an optional technical solution of this embodiment, referring mainly to fig. 1-3, the material transporting and distributing device further includes a material receiving cavity, and the dividing member 100 is disposed in the material receiving cavity and divides the material receiving cavity into a first cavity 410 and a second cavity 420.
Preferably, the dividing plate is installed in the receiving cavity and is used for dividing the receiving cavity into a first cavity 410 and a second cavity 420 which are not communicated with each other.
Specifically, material flow 200 is divided by divider 100 to form a first material flow and a second material flow, first cavity 410 is for receiving the first material flow, and second cavity 420 is for receiving the second material flow. The arrangement of the first and second cavities 410, 420 facilitates the collection of the divided first and second streams.
As shown in FIG. 2, the left end in FIG. 2 is the left end, and the right end is the right end. When the material flow 200 intersects the left end of the linear divider 110, i.e., the first material flow trajectory 210 intersects the left end of the linear divider 110 in fig. 2, the material flow 200 is not divided by the linear divider 110, and all of the material flows into the first cavity 410. When the stream 200 intersects somewhere within the maximum span of the linear divider 110, i.e., in fig. 2, the second stream trajectory line 220 intersects somewhere between the left and right ends of the linear divider 110, the stream 200 is divided proportionally by the linear divider 110. When the material flow 200 intersects the right end of the linear divider 110, i.e., the third material flow trajectory line 230 intersects the right end of the linear divider 110 in fig. 2, the material flow 200 is not divided by the linear divider 110, and all of the material flows into the second chamber 420.
As shown in fig. 3, when the material flow 200 intersects the left end of the bending type divider 120, i.e., the first material flow trajectory 210 intersects the left end of the bending type divider 120 in fig. 3, the material flow 200 is not divided by the bending type divider 120, and the entire material flows into the first cavity 410. When material flow 200 intersects somewhere within the maximum right-left span of bend-type segment 120, i.e., in fig. 3, second material flow trajectory 220 intersects somewhere between the right and left ends of bend-type segment 120, material flow 200 is proportionally divided by bend-type segment 120. When material flow 200 intersects the right end of bend type segment 120, i.e., in fig. 3, third material flow trajectory 230 intersects the right end of bend type segment 120, material flow 200 is not divided by bend type segment 120, and all of the material flows into second chamber 420.
When the conveying speed of belt conveyor 300 is a first speed, material flow 200 will pass through first material flow trajectory 210; when the conveying speed of the belt conveyor 300 is the second speed, the material flow 200 will pass through the third material flow trajectory line 230; when the conveying speed of belt conveyor 300 is between the first speed and the second speed, material flow 200 will pass through a trajectory between first material flow trajectory 210 and third material flow trajectory 230.
