Description

Technical Field

[0001] This utility model relates to the field of sand and gravel vibrating screen technology, specifically a sand and gravel vibrating screen that facilitates material feeding. Background Technology

[0002] Before being put into use, sand and gravel need to be screened by a vibrating screen to achieve screening of sand and gravel of different particle sizes, which facilitates subsequent processing and use.

[0003] In related technologies, most vibrating screens use conveyor belts for feeding to achieve automatic delivery of sand and gravel. However, when the vibrating screen is stopped for a few minutes for cleaning and maintenance, the conveyor belt needs to be turned off. After the vibrating screen is cleaned and maintained, the conveyor belt needs to be turned on again. Cleaning and maintaining the vibrating screen will affect the sand and gravel transportation process and may also cause material interruption in the production line, which is not conducive to continuous operation. Utility Model Content

[0004] The purpose of this utility model is to provide a sand and gravel vibrating screen that facilitates feeding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel vibrating screen that facilitates feeding, including a support frame, on which a belt conveyor and a vibrating screen are installed, with the vibrating screen located above the belt conveyor. The finer sand and gravel in the vibrating screen fall onto the belt conveyor and are conveyed out, which can prevent the accumulation of sand and gravel and facilitate continuous processing of sand and gravel.

[0006] The hopper is installed on the upper end of the support. The hopper has an inclined surface. A feeder is connected to the side of the hopper through a fixing plate. The feeder is located below the outlet of the hopper. The feeder is used to transport sand and gravel to the vibrating screen. The hopper can temporarily store sand and gravel and temporarily clean and maintain the vibrating screen without affecting the transport of sand and gravel.

[0007] A fixed frame is connected to the side of the hopper. Several staggered baffles are inserted into the left and right sides of the fixed frame. Two electric cylinders are installed on the upper surface of the fixed frame. The electric cylinders are connected to the corresponding baffles. The baffles on the left and right sides are connected to linkage plates. The electric cylinders are connected to the linkage plates through control arms. The electric cylinders control the baffles to move closer to each other, which can control the size of the sand and gravel outlet. The amount of sand and gravel received by the vibrating screen can also be controlled by the feeder, which can quickly process the sand and gravel stored in the hopper.

[0008] Furthermore, the belt conveyor is rotatably mounted with support legs on its side, and the belt conveyor is equipped with an outlet bucket at its upper end. The outlet bucket ensures that the sand and gravel fall downwards, making it convenient to send the sand and gravel to other belt conveyors for transfer.

[0009] Furthermore, a fixed seat is installed on the upper surface and inside of the belt conveyor. The fixed seat is equipped with two V-shaped auxiliary rollers to support the belt of the belt conveyor and prevent the belt from bending excessively.

[0010] Furthermore, a stone discharge hopper is fixedly connected to the support. The stone discharge hopper is located below the vibrating screen. Coarser sand and gravel fall along the stone discharge hopper to the side of the support. Other belt conveyors can also be used to collect the sand and gravel.

[0011] Furthermore, the feeder has several support rollers inside to ensure that the feeder stably blocks the hopper and reduces the amount of sand and gravel leakage.

[0012] Furthermore, several rollers are installed on the fixed frame, and the rollers are in rolling connection with the stop post to ensure that the stop post moves smoothly and there will be no jamming or wear problems.

[0013] Furthermore, a splash guard is connected to the support frame. The splash guard is located below the vibrating screen, which can ensure that all the finer sand and gravel fall onto the belt conveyor and prevent the sand and gravel from splashing everywhere.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The hopper can store sand and gravel. When the vibrating screen is temporarily cleaned and maintained, the sand and gravel can continue to be conveyed to the hopper, which will not cause the production line to be interrupted. The switching steps of the conveyor belt are reduced, and the continuous processing of sand and gravel can be quickly restored.

[0016] (2) The feeder transports the sand and gravel in the hopper to the vibrating screen. The speed of the feeder can be adjusted to control the amount of sand and gravel transported. When there is a lot of sand and gravel in the hopper, the speed of the feeder can be increased to prevent the sand and gravel from overflowing from the hopper. It can also stabilize the amount of material fed to the vibrating screen.

[0017] (3) The electric cylinder pushes the baffle to open or close, which can adjust the size of the sand and gravel outlet. When cleaning and maintaining the vibrating screen, closing the baffle can prevent sand and gravel from being discharged from the hopper and will not affect the cleaning of the vibrating screen.

[0018] (4) The vibrating screen sends the finer sand and gravel to the belt conveyor, while the coarser sand and gravel are discharged from the discharge hopper. With the help of the belt conveyor, the finer sand and gravel can be quickly transported out, avoiding the accumulation of finer sand and gravel, and will not affect the continuous screening of sand and gravel by the vibrating screen.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figure 1-6 This utility model provides a technical solution: a sand and gravel vibrating screen for easy feeding, including a support 1, on which a belt conveyor 2 and a vibrating screen 6 are installed, and the vibrating screen 6 is located above the belt conveyor 2. The belt conveyor 2 and the vibrating screen 6 are tilted synchronously. When sand and gravel fall onto the vibrating screen 6, the finer sand and gravel fall onto the belt conveyor 2, and the coarser sand and gravel fall along the vibrating screen 6 into the stone discharge hopper 7.

[0029] The hopper 9 is installed on the upper end of the bracket 1. The hopper 9 has an inclined surface. The side of the hopper 9 is connected to the feeder 11 through the fixing plate 10. The feeder 11 is located below the outlet of the hopper 9. The inclined surface can guide the sand and gravel to be conveyed to the feeder 11. The feeder 11 conveys the sand and gravel for the vibrating screen 6. The feeder 11 adopts a belt conveyor. Metal belts are preferred for conveying sand and gravel to avoid rapid wear of the conveyor belt. Rubber conveyor belts with strong wear resistance can also be used. The feeder 11 blocks the opening below the hopper 9.

[0030] A fixed frame 15 is connected to the side of the hopper 9. Several staggered baffles 14 are inserted into the left and right sides of the fixed frame 15. Two electric cylinders 16 are installed on the upper surface of the fixed frame 15. The electric cylinders 16 are connected to the corresponding baffles 14. The baffles 14 block the openings on the side of the hopper 9. The baffles 14 on the left and right sides are close to each other to reduce the outflow of sand and gravel. The baffles 14 on the left and right sides are far apart to increase the outflow of sand and gravel.

[0031] In this embodiment, as Figure 1 As shown, the belt conveyor 2 is rotatably mounted with support legs 3 on its side to provide stable support for the left end of the belt conveyor 2. The belt conveyor 2 is provided with an outlet bucket 4 at its upper end, which can prevent sand and gravel from flying out and guide all the sandpaper to fall downwards. Multiple belt conveyors 2 can be used to transport sand and gravel to a designated location.

[0032] In this embodiment, as Figure 5 As shown, a fixed seat 5 is installed on the upper surface and inside of the belt conveyor 2. The fixed seat 5 is equipped with two auxiliary rollers 19 arranged in a V-shape. The auxiliary rollers 19 support the belt of the belt conveyor 2. The belt has a certain curvature to prevent sand and gravel from scattering from both sides of the belt when transporting sand and gravel.

[0033] In this embodiment, as Figure 1 As shown, a stone discharge hopper 7 is fixedly connected to the support 1. The stone discharge hopper 7 is located below the vibrating screen 6. The stone discharge hopper 7 concentrates and guides the coarser sand and gravel to the side of the support 1, and the coarser sand and gravel can be transported out by the belt conveyor 2.

[0034] In this embodiment, as Figure 5 As shown, the feeder 11 has several support rollers 18 inside, which can keep the feeder 11 flat, so that the distance between the feeder 11 and the hopper 9 will not increase, and the effect of preventing sand and gravel leakage is good.

[0035] In this embodiment, as Figure 4 As shown, several rollers 13 are installed on the fixed frame 15. The rollers 13 are tactilely connected to the stop post 14. When the stop post 14 moves, the rollers 13 rotate, which can reduce the moving resistance of the stop post 14 and ensure that the stop post 14 will not get stuck. The stop post 14 is made of steel and has good wear resistance. It can maintain a good sand and gravel blocking effect after long-term use.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the left and right side stops 14 are respectively connected to the linkage plate 12. The electric cylinder 16 is connected to the linkage plate 12 through the control arm 17, so that the electric cylinder 16 can control all the stops 14 on one side.

[0037] In this embodiment, as Figure 1 As shown, a splash guard 8 is connected to the support 1. The splash guard 8 is located below the vibrating screen 6. During the process of sand and gravel falling onto the belt conveyor 2, the splash guard 8 can ensure that all the sand and gravel fall onto the belt conveyor 2.

[0038] Specifically, during use, an additional belt conveyor 2 is used to transport sand and gravel into hopper 9. The electric cylinder 16 drives the baffle 14 to move through the control arm 17 and the linkage plate 12. The baffles 14 on both sides move away from each other and no longer block the flow of sand and gravel. The feeder 11 works to transport the sand and gravel in hopper 9 to vibrating screen 6. The vibrating screen 6 works to shake the finer sand and gravel onto belt conveyor 2. Belt conveyor 2 transports the sand and gravel out, while the coarser sand and gravel fall onto the discharge hopper 7 along the vibrating screen 6.

[0039] When performing temporary cleaning and maintenance on the vibrating screen 6, the electric cylinder 16 controls the baffles 14 on both sides to move closer together, blocking the flow of sand and gravel, and shutting off the feeder 11, so that sand and gravel are no longer transported to the vibrating screen 6. At this time, the hopper 9 can hold a portion of sand and gravel without interrupting the transport of sand and gravel. After the cleaning and maintenance of the vibrating screen 6 is completed, the baffles 14 move further apart, and the feeder 11 continues to work. At this time, the opening of the baffles 14 and the working speed of the feeder 11 can be increased to transport the sand and gravel in the hopper 9 to the vibrating screen 6 as quickly as possible. This can prevent the sand and gravel from overflowing from the hopper 9, making it more convenient to transport sand and gravel to the vibrating screen 6, which is beneficial for the continuous processing of sand and gravel.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
