[0002] A vibrating screen is a device that uses vibration for screening. It uses an exciter or a vibrating motor to generate vibration. The screen mesh on the screen body and the vibrator form a screening mechanism. When the material passes through the screen mesh, due to the vibration of the screen body, the material is subjected to forces of different magnitudes and directions on the screen surface, so that the material is stratified and passes through the screen according to the particle size, achieving the purpose of screening. When screening materials through a vibrating screen, generally, the feeding port of the vibrating screen needs to be opened, and the materials to be screened are sent into the feeding port through a conveying device (such as a conveyor belt) or directly poured. Subsequently, after the materials enter the vibrating screen, under the vibration of the screen body, the screening process on the screen surface begins.

[0003] In the prior art, when screening materials through a vibrating screen, in order to control the feeding of materials, a material distributor and a bar valve are usually arranged in the hopper of the materials to achieve the control of material distribution and adjustment. However, since the bar valve cannot distribute materials, and the material distributor cannot be used as a regulating valve, the distribution and adjustment of materials are not convenient enough, and further the screening of materials is not flexible enough. Therefore, in order to solve the above problems, a material distribution and adjustment device for a vibrating screen is proposed. Content of the Utility Model

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-7 , an embodiment provided by the present utility model:

[0025] The first telescopic cylinder 21 and the second telescopic cylinder 25 used in this application are products that can be directly purchased on the market. Their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0026] A material distribution adjusting device for a vibrating screen, comprising a housing. The housing includes a hopper 1, and a material pipe 11 is fixedly connected to the bottom end of the hopper 1. Through the setting of the hopper 1, materials can be input, and then the materials can enter the material pipe 11 through the hopper 1 and fall onto the vibrating screen through the material pipe 11 for screening;

[0027] A material distribution mechanism is arranged inside the hopper 1. The material distribution mechanism includes a first fixing plate 2. The first fixing plate 2 is fixedly connected to the surface of the hopper 1. A first telescopic cylinder 21 is fixedly installed inside the first fixing plate 2. The output end of the first telescopic cylinder 21 is fixedly connected to a first connecting plate 22. A first bar 23 is fixedly connected to the surface of the first connecting plate 22. A second fixing plate 24 is fixedly connected to the surface of the hopper 1. A second telescopic cylinder 25 is fixedly installed inside the second fixing plate 24. The output end of the second telescopic cylinder 25 is fixedly installed with a second connecting plate 26. A connecting rod 27 is fixedly connected to the inside of the second connecting plate 26. A second bar 28 is arranged on the surface of the connecting rod 27. Through the telescopic movement of the second telescopic cylinder 25, the second connecting plate 26 can drive the connecting rod 27 and the second bar 28 to move, and then the telescopic movement of the second bar 28 can adjust the amount of material distribution, making the screening more flexible.

[0028] Furthermore, the first bar 23 moves inside the hopper 1, the connecting rod 27 moves inside the second bar 28, and the second bar 28 moves inside the hopper 1. Through the movement of the first bar 23, the materials in the hopper 1 can flexibly enter the two groups of material pipes 11 under the action of the first bar 23, so as to achieve the effect of material distribution.

[0029] Furthermore, a fixing mechanism is arranged inside the connecting rod 27. The fixing mechanism includes a third fixing plate 3. The third fixing plate 3 is fixedly connected to the surface of the second connecting plate 26. A third telescopic cylinder 31 is fixedly installed inside the third fixing plate 3. The output end of the third telescopic cylinder 31 is fixedly connected to a fixing rod 32. A connecting block 33 is fixedly connected to the surface of the fixing rod 32. A chute 34 is opened inside the connecting rod 27. A slider 35 is movably connected to the surface of the chute 34. A clamping block 36 is fixedly connected to the surface of the slider 35. A clamping groove 37 is opened on the inner wall of the second bar 28. A spring 38 is fixedly connected to the surface of the slider 35. By separating the clamping block 36 from the clamping groove 37 through movement, the fixation between the connecting rod 27 and the second bar 28 can be released. Then, when the second telescopic cylinder 25 contracts, the second connecting plate 26 drives the connecting rod 27 to move, so that the corresponding second bar 28 will not move, and the telescopic movement of the second bar 28 is more flexible.

[0030] Further, both the fixed rod 32 and the connecting block 33 are movable inside the connecting rod 27. Two groups of sliding grooves 34 are formed inside the connecting rod 27. By driving the connecting block 33 to move with the fixed rod 32, the connecting block 33 can be used to squeeze the clamping block 36, so that the clamping block 36 can be engaged with the clamping groove 37, which is convenient for fixing the connecting rod 27 and the second bar 28. Thus, when the second telescopic cylinder 25 expands and contracts, the connecting rod 27 can drive the second bar 28 to move accordingly, and the second bar 28 can achieve the effect of distributing materials.

[0031] Further, one end of the slider 35 is movably connected to the sliding groove 34, and the other end of the slider 35 is fixedly connected to the clamping block 36. By sliding the slider 35 on the surface of the sliding groove 34, it is convenient for the clamping block 36 to stably move inside the connecting rod 27 under the action of the connecting block 33.

[0032] Further, two groups of clamping grooves 37 are formed on the inner wall of the second bar 28. One end of the spring 38 is fixedly connected to the sliding groove 34, and the other end of the spring 38 is fixedly connected to the slider 35. Through the arrangement of the spring 38, the clamping block 36 can be reset, and then the separation of the clamping block 36 and the clamping groove 37 can be realized, so that the fixation of the connecting rod 27 and the second bar 28 can be cancelled.

[0033] Working principle: During use, the first telescopic cylinder 21 is electrically connected to an external power source. The staff starts the first telescopic cylinder 21 by pressing a switch. By controlling the expansion and contraction of two different groups of the first telescopic cylinders 21, the corresponding first connecting plates 22 will be driven to move, and then the corresponding first bars 23 will move inside the hopper 1 accordingly, so that the materials can enter the corresponding material pipes 11 under the action of the first bars 23, thus realizing the distribution of the materials. The second telescopic cylinder 25 is electrically connected to an external power source. The staff starts the second telescopic cylinder 25 by pressing a switch. When the second telescopic cylinder 25 expands and contracts, the second connecting plate 26 can drive the connecting rod 27 and the second bar 28 to move accordingly. Through the movement of the second bar 28, the materials entering the material pipe 11 can be adjusted, so that the feeding amount of the materials can be controlled.

[0034] The third telescopic cylinder 31 is electrically connected to an external power supply. The operator starts the third telescopic cylinder 31 by pressing a switch. The telescoping of the third telescopic cylinder 31 can drive the fixed rod 32 to move inside the connecting rod 27, and then the connecting block 33 moves accordingly. By the movement of the connecting block 33, the clamping block 36 is squeezed, so that the clamping block 36 slides on the surface of the chute 34 through the slider 35. At this time, the spring 38 is in a stretched state, realizing the engagement of the clamping block 36 and the clamping groove 37, achieving the effect of fixing the connecting rod 27 and the second rod 28. Then, when the second telescopic cylinder 25 contracts, the second rod 28 can move accordingly under the action of the connecting rod 27. By the movement of the connecting block 33, the extrusion of the clamping block 36 is cancelled, and the slider 35 will reset under the resilience of the spring 38. Then, the engagement of the clamping block 36 and the clamping groove 37 is cancelled, thus releasing the fixation of the connecting rod 27 and the second rod 28, so that when the second telescopic cylinder 25 expands and contracts, the second rod 28 will not move accordingly under the action of the connecting rod 27, and thus it can be achieved that when controlling the expansion and contraction of the second telescopic cylinder 25, the adjustment of materials by different numbers of second rods 28 can be realized.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art can smoothly implement the present invention according to the illustrations in the specification and the above content. However, any equivalent changes such as slight modifications, refinements, and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
