Description

Technical Field

[0001] The invention discloses a multi-point material distribution system, belonging to the technical field of material conveying. Background Art

[0002] Belt conveyor is a kind of material conveying equipment widely used in many fields such as coal, with the advantages of strong conveying capacity and long conveying distance. In the traditional working state of belt conveyor, in addition to setting a discharge end at the end to collect materials, several unloading points can also be set along the transportation direction of the belt conveyor to realize multi-point unloading of materials, so as to meet the needs of conveying materials to different locations. In the prior art, the technical solutions that can realize multi-point unloading mainly include the following:

[0003] (1) The Chinese utility model patent application number 201520033395.5, filed on January 19, 2015, and entitled “Multi-point simultaneous unloading concrete continuous conveying device” discloses a technical solution in which a baffle driven by a hydraulic cylinder is provided at the end of the front-stage feeding belt conveyor, and the swing direction of the baffle is controlled by the hydraulic cylinder to achieve multi-point unloading. The disadvantage of this method is that only two-point unloading can be achieved by the hydraulic cylinder. When more unloading points are required, the complexity of its mechanical mechanism will increase exponentially.

[0004] (2) The Chinese utility model patent with application number 202320224075.2, application date February 14, 2023, and patent name “A multi-point unloading device for a belt conveyor” discloses a technical solution in which multiple discharge ports are arranged on the surface of the belt conveyor, and when the material moves to the corresponding discharge port, it automatically enters to complete multi-point unloading. The advantage of this solution is its simple structure, but its disadvantage is that when the unloading point is fixed, the working state of the unloading point cannot be controlled. Therefore, this method is only applicable to occasions where the unloading point is fixed, and therefore it is more restrictive.

[0005] (3) The Chinese utility model patent with application number 201721617925.6, application date November 28, 2017, and patent name “A belt unloading device”, and the Chinese invention patent with application number 202210065930.X, application date January 20, 2022, and patent name “A multi-stage plow-type unloading system” respectively disclose their respective technical solutions. Both of the above technical solutions adopt a plow-type unloading method, which uses a plow controlled by a piston rod. When a certain unloading point needs to be unloaded, the plow is moved to the surface of the belt conveyor, and the material is unloaded under the guidance of the plow. When the point does not need to be unloaded, the piston cylinder controls the plow to move away from the belt conveyor. The advantage of this method is that the state of a certain unloading point can be selected according to needs, but the disadvantage of the plow-type unloading method is that it is only suitable for unloading smaller materials, not large bulk materials.

[0006] (4) The Chinese utility model patent with application number 202220782498.1 and application date April 2, 2022, and patent name “A belt conveyor with multi-point unloading” discloses a technical solution in which two hoppers controlled by a cylinder are used to control the unloading, overcoming the limitation that the plow blade unloading method is difficult to use for unloading large pieces of material, and can control whether each unloading point is unloading. The defect of this method is that each unloading point is set up above the belt conveyor. If the number of unloading points needs to be increased or decreased, the machine needs to be stopped and disassembled, which affects normal operation. In addition, the direction of the belt is changed by a redirecting roller at each unloading point. Therefore, the length of the belt needs to be changed at the same time to increase or decrease the number of unloading points, so its flexibility is poor. Utility Model Content

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In this multi-point material distribution system, by independently setting up multiple distribution conveyors on the side of the main conveyor, while achieving independent material distribution at each location, since the distribution conveyor at each location is set separately from the main conveyor, the distribution conveyor can be increased or reduced while the main conveyor always keeps working, and the flexibility is greatly increased.

DETAILED DESCRIPTION

[0026] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0027] like Figure 1 As shown, a multi-point material distribution system (hereinafter referred to as the material distribution system) includes a main conveyor, which is implemented by a belt conveyor commonly used in the art, including a main conveying frame 3, at both ends of which are respectively provided an active roller 7 and a driven roller 1, and a main conveying belt 6 passes around the active roller 7 and the driven roller 1. The main conveying belt 6 runs along the main conveying frame 3 driven by the active roller 7.

[0028] Material baffles 2 are provided on both sides of the feed end of the main conveyor, and the material baffles 2 are fixed to the upper parts of both sides of the feed end through brackets fixed to the outside of the main conveying frame 3 to ensure that the materials can smoothly fall on the surface of the main conveying belt 6 for transmission. A number of fixed rollers 4 are arranged along the extension direction of the main conveying belt 6 between the feed end and the discharge end of the main conveyor to support the main conveying belt 6. The fixed rollers 4 are implemented by a well-known structure in the art: including a roller bracket and a plurality of rollers installed above the roller bracket, and the specific structure thereof will not be repeated again.

[0029] In the material sorting system, main conveying rails are respectively arranged on both sides of the upper end of the main conveying frame 3, and a material dividing vehicle 5 is movably arranged on the upper part of the main conveying frame 3, and the main conveying belt 6 passes through the material dividing vehicle 5 at the same time. On the side of the main conveying frame 3, a plurality of material dividing conveyors ( Figure 1 The material distribution conveyor is arranged vertically with the main conveyor. When the material needs to be distributed to a certain material distribution conveyor, the material distribution vehicle 5 moves to the corresponding material distribution conveyor, and the feeding end of the material distribution conveyor moves to the unloading end of the main conveyor. After the material distribution conveyor and the main conveyor are connected, the material distribution is completed. A fixed material receiving mechanism ( Figure 1 Not shown), such as a silo, if each material distribution conveyor distributes materials equally, the materials on the surface of the main conveying belt 6 fall into the material receiving mechanism.

[0030] like Figure 5 As shown, the material dividing conveyor is also implemented with a structure similar to that of the belt conveyor in the field, including a material dividing conveying frame 17, a material dividing active roller 22 is arranged at one end of the material dividing conveying frame 17, a plurality of material dividing rollers 18 are arranged on the inner side of the material dividing conveying frame 17, and a material dividing conveyor belt 19 is simultaneously sleeved on the outer side of the material dividing conveying roller 22 and all the material dividing rollers 18.

[0031] A base frame is provided at the bottom of the material distribution and conveying frame 17, a material distribution bottom wheel 20 is installed at the bottom of the base frame, a material distribution guide rail 21 is also laid at the bottom of the material distribution conveyor, and the material distribution bottom wheel 20 is installed on the surface of the material distribution guide rail 21. A driving cylinder 23 is also provided at the lower part of the material distribution and conveying frame 17, and the piston rod of the driving cylinder 23 is connected to the bottom of the material distribution and conveying frame 17, and the driving cylinder 23 drives the material distribution conveyor to dock or separate with the material distribution vehicle 5.

[0032] like Figures 2~4As shown, the material distribution vehicle 5 includes two material distribution brackets 9 arranged opposite to each other, the two material distribution brackets 9 are plate-shaped structures, and the two material distribution brackets 9 are connected and fixed by multiple connecting frames 16. A bottom wheel mechanism 12 is respectively arranged at the bottom of each material distribution bracket 9, and the bottom wheel mechanisms 12 on both sides are respectively clamped on the two main conveying guide rails at the upper end of the main conveying frame 3. The width of the above-mentioned fixed roller 4 is smaller than the spacing between the bottom wheel mechanisms 12 on both sides, and the material blocking plates 2 on both sides at the feeding end of the main conveyor are respectively located on the outside of the bottom wheel mechanisms 12 on both sides, so the fixed roller 4 and the material blocking plate 2 will not hinder the movement of the material distribution vehicle 5 along the main conveying frame 3.

[0033] Discharge rollers 10 are rotatably mounted on the top of the material distribution brackets 9 on both sides, and redirection rollers 13 are rotatably mounted on the bottom of the material distribution brackets 9 on both sides. The discharge rollers 10 and redirection rollers 13 are arranged alternately up and down. The main conveyor belt 6 first bypasses the outer side of the discharge roller 10 in the material distribution vehicle 5, and then reverses downward and bypasses the rear side of the redirection roller 13. Since the discharge roller 10 is located on the front side above the redirection roller 13, the discharge roller 10 is the discharge end of the material distribution vehicle 5. The material transported by the main conveyor belt 6 falls at the discharge roller 10, and then is further transported with the main conveyor belt 6. If material distribution is required, the material distribution conveyor belt 19 advances to the bottom of the discharge roller 10 to receive the material.

[0034] A roller fixing frame 11 is arranged on the inner side of each material distribution bracket 9, and the roller fixing frames 11 on both sides are tilted at the same angle, and multiple groups of mobile rollers 8 are arranged between the roller fixing frames 11 on both sides. The structure of the mobile roller 8 is the same as that of the fixed roller 4, and the two ends of the roller bracket of the mobile roller 8 are respectively fixed on the inner side of the roller fixing frames 11 on both sides, and the roller of the mobile roller 8 is installed on the surface of its roller bracket.

[0035] Along the forward direction of the main conveyor belt 6, the height of the movable roller 8 increases successively, so that the main conveyor belt 6 extends upward to the discharge roller 10. In the process of the distributor 5 moving along the main conveyor frame 3, the main conveyor belt 6 is supported by the fixed rollers 4 at different positions within the range of the main conveyor frame 3, and the main conveyor belt 6 is supported by the movable rollers 8 after entering the distributor 5.

[0036] The bottom wheel mechanism 12 located at the bottom of the material distribution frame 9 includes two rollers fixed by a wheel frame, and a driving mechanism 14 is fixed at one of the connecting frames 16 of the material distribution bracket 9. The driving mechanism 14 includes a driving motor and a reducer installed at the motor shaft of the driving motor, and transmission shafts 15 are respectively led out from both ends of the reducer, and the transmission shafts 15 on both sides are respectively connected to one of the rollers of the bottom wheel mechanism 12 on both sides. The roller connected to the transmission shaft 15 in the bottom wheel mechanism 12 on both sides is the driving wheel, and the other is the driven wheel. The movement of the material distribution vehicle 5 along the main conveying frame 3 is realized by setting the driving mechanism 14.

[0037] The specific working process and working principle are as follows:

[0038] The material enters from the feeding end of the main conveyor and is transported by the main conveyor belt 6 . During the process of being transported on the surface of the main conveyor belt 6 , the material enters the material distribution vehicle 5 along the main conveyor belt 6 .

[0039] After entering the material distribution vehicle 5, the main conveyor belt 6 rises to the discharge roller 10 under the support and guidance of the mobile roller 8, and the material transported by the main conveyor belt 6 falls at the discharge roller 10, and then is further transported with the main conveyor belt 6. When material distribution is required at a certain material distribution conveyor belt 19, the drive mechanism 14 is activated to move the material distribution vehicle 5 to the corresponding material distribution conveyor belt 19, and then the corresponding drive cylinder 23 is activated to move the material distribution conveyor frame 17 to the bottom of the discharge roller 10, and the material output from the discharge roller 10 falls to the surface of the material distribution conveyor belt 19, realizing material distribution. The materials not distributed to any material distribution conveyor are finally collected by the silo at the end of the main conveyor or further transported.

[0040] From the above, it can be seen that in this material sorting system, multiple sorting conveyors are arranged on the side of the main conveyor and connected to it. While realizing independent material sorting at each location, since the sorting conveyor at each location is separately arranged from the main conveyor, the sorting conveyors can be increased or reduced while the main conveyor always remains in working condition, and the flexibility is greatly increased.

[0041] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
