Description

Technical Field

[0001] The invention relates to the technical field of sand screening, and in particular to a high-efficiency sand screening device. Background Art

[0002] Sand screening is often used in construction sand screening and beach garbage cleaning. In actual application, sand screening is mostly done through a screen, which is often clogged due to the particle size of sand and excessive accumulation. Based on this, in the existing process of using a screen to screen sand, a vibration structure is generally added to enable the screen to screen sand, thereby reducing the probability of the screen being clogged, and at the same time, it can also improve the efficiency of the screen to screen sand to a certain extent.

[0003] The vibration structure of the existing sand screening device mostly has a single and regular vibration direction. For example, the screen is vibrated in the direction of elastic expansion and contraction through the cooperation of a spring and a corresponding rotating cam. The single vibration structure will cause the directions of the movement of sand mixed with impurities to be mostly consistent during the process of the screen screening sand, that is, the distance between sand and sand, or between sand and impurities, cannot be increased. Therefore, the vibration structure has a low increase in the efficiency of the screen to screen sand. In addition, the existing sand screening device cannot facilitate the staff to clean the remaining large-particle sand or impurities from the screen, thereby increasing the workload of the staff and reducing the efficiency of subsequent sand screening using the screen. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the vibration direction of the vibration component in the sand screening device in the prior art is single and regular, which results in a low increase in the efficiency of the screen to screen sand, and to provide a high-efficiency sand screening device.

[0005] The present invention solves the above-mentioned technical problems and adopts the following technical solutions: an efficient sand screening device, comprising a bearing shaft and a bearing frame supporting the end of the bearing shaft, a vibrating bucket is arranged on the bearing shaft, a screen and a vibrating assembly are arranged at the edge of the vibrating bucket away from the bearing shaft, and the vibrating assembly allows the vibrating bucket to deflect irregularly around the bearing shaft;

[0006] The vibration assembly includes a power shaft rotatably mounted on a carrier and a V-plate rotatably connected to the vibration bucket at one side. The power shaft is driven by a driving assembly mounted on the carrier. A cam plate is fixedly mounted on one end of the power shaft facing the vibration bucket. The cam plate is provided with a wave element hinged to the V-plate at the top corner.

[0007] The wave member comprises two hinged plates respectively hinged to two protrusions of the cam plate, and hinged grooves are provided on the two hinged plates, and the opposite ends of the two hinged grooves are hinged to the other side of the V-plate.

[0008] As a further optimization of the high-efficiency sand screening device of the present invention: a counterweight block is provided at the top corner of the V-plate.

[0009] As a further optimization of the high-efficiency sand screening device of the present invention: the bearing shaft slides in the long groove opened on the vibration bucket.

[0010] As a further optimization of the high-efficiency sand screening device of the present invention: a debris removal component for assisting in the discharge of impurities is provided at the bottom of the vibrating bucket, the debris removal component includes winding drums arranged on both sides of the vibrating bucket and four discharge ports distributed in a rectangular shape and opened at the center of the vibrating bucket, two winding drums are provided with rotating winding shafts, and barrier cloths for covering the discharge ports are wound on the two winding shafts, and clamping blocks are provided at the opposite ends of the two barrier cloths, and the clamping blocks are arranged on the vibrating bucket corresponding to the discharge ports.

[0011] As a further optimization of the high-efficiency sand screening device of the present invention: the ends of the two winding shafts passing through the winding drum are both driven by winding motors, and the winding motors are fixed on the vibration bucket.

[0012] As a further optimization of the high-efficiency sand screening device of the present invention: the screen is inclined with the bottom close to the bearing shaft and the top away from the bearing shaft.

[0013] As a further optimization of the high-efficiency sand screening device of the present invention: two vibration components are provided, and the two vibration components are respectively arranged between the two sides of the supporting frame and the corresponding two sides of the vibration bucket, and the two vibration components are respectively driven by a driving component.

[0014] As a further optimization of the high-efficiency sand screening device of the present invention: the driving assembly includes a driving motor arranged on a supporting frame, and the driving motor is driven by a transmission assembly and a power shaft through a transmission belt.

[0015] As a further optimization of the high-efficiency sand screening device of the present invention: the transmission component includes a transmission shaft with two ends rotatably arranged on two bearing frames, a transmission belt is arranged on the transmission shaft, and the transmission belt is arranged above the corresponding vibration bucket.

[0016] As a further optimization of the high-efficiency sand screening device of the present invention: the hinged plate, the V-plate and the cam plate are all hinged by shoulder screws, and a ceramic layer is provided on the surface of the shoulder screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention drives the cam plate to rotate by arranging a driving component. During the rotation of the cam plate, different shapes are formed due to the influence of centrifugal force, the V-plate connecting the vibrating bucket and the weight of the sand in the vibrating bucket. At the same time, the two sides of the V-plate are deformed close to each other, so that the deflection amplitude and direction of the vibrating bucket around the bearing axis are irregular. Then, the sand and weight in the vibrating bucket will fly in different directions and with different initial throwing speeds. Subsequently, the sand and the sand as well as the sand and the impurities will be quickly broken up, and then the probability of the screen being blocked will be reduced. Then, the probability of sand with corresponding particle size passing through the screen will be increased, that is, the efficiency of the screen screening sand will be improved.

[0019] Furthermore, the present invention drives the cam plate to rotate by arranging a driving assembly. During the rotation of the cam plate, different shapes will be formed due to the influence of centrifugal force, the V-plate connecting the vibrating bucket and the weight of the sand in the vibrating bucket. At the same time, the two sides of the V-plate will deform toward each other, thereby making the deflection amplitude and direction of the vibrating bucket around the load-bearing axis irregular, that is, making the vibration amplitude and vibration angle of the screen irregular, and then the impurities or sand blocked in the mesh of the vibrating screen will be discharged. At the same time, the irregular vibration will also reduce the probability of impurities or sand entering the mesh of the screen, thereby reducing the probability of the mesh of the screen being blocked, that is, reducing the occurrence of reduced sand screening efficiency during long-term use of the device.

[0028] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0029] <Example 1>

[0030] like Figure 1-5 As shown, a high-efficiency sand screening device, which is the same as the prior art, includes a load-bearing shaft 4 and a load-bearing frame 2 rotatably connected to both ends of the load-bearing shaft 4, so as to support and position the corresponding position of the load-bearing shaft 4, and a vibrating bucket 5 is provided on the load-bearing shaft 4, and a screen 8 is provided on the vibrating bucket 5, and the screen 8 is inclined with the bottom close to the top of the load-bearing shaft 4 away from the load-bearing shaft 4. Then, the sand will be screened through the screen holes of the screen 8 with the assistance of gravity, and at the same time, the probability of impurities clogging the mesh holes of the screen 8 can be reduced to a certain extent. The screen 8 can dry out the sand entering the vibrating bucket 5 when the vibrating bucket 5 flips around the load-bearing shaft 4.

[0031] Different from the prior art, a vibration assembly 7 is provided between both sides of the vibration bucket 5 and both sides of the carrier frame 2. Both vibration assemblies 7 are driven by a driving assembly 1. The two driving assemblies 1 are respectively provided on both sides of the carrier frame 2. The vibration assembly 7 includes a transmission shaft 302 rotatably provided on the carrier frame 2 and driven by the driving assembly 1. A cam plate 702 is fixedly provided on the side of the transmission shaft 302 facing the vibration bucket 5. Both protrusions of the cam plate 702 are hinged with hinge plates 7031. Both hinge plates 7031 are provided with hinge grooves 7032. Specifically, the hinge grooves 7032 are key grooves. A V-plate 704 is provided between the opposite ends of the two hinge grooves 7032 and the vibration bucket 5. Specifically, one side of the V-plate 704 is hinged to the vibration bucket 5 away from the bearing shaft 4, and the other side of the V-plate 704 is hinged to the two hinge grooves 7032. When the driving assembly 1 drives the cam plate 702 to rotate, the centrifugal force driven by the driving assembly 1 to rotate the cam plate 702 drives the two hinge plates 7031 to drive the two hinge plates The connecting plate 7031 has a tendency to rotate at different amplitudes. During the rotation of the two hinged plates 7031 at different amplitudes, the two hinge grooves 7032, the V-plate 704, the vibrating bucket 5, the sand of different weights in the vibrating bucket 5, and the deformation of the two sides of the V-plate 704 approaching and moving away from each other will be used to make the vibrating bucket 5 relatively irregularly deflect around the load-bearing axis 4 at different angles and amplitudes, thereby causing the sand in the vibrating bucket 5 to disperse in different directions and under different initial throwing speeds, that is, to separate sand of different particle sizes and between sand and impurities, and reduce the probability of clogging of the mesh of the screen 8. Even if it is clogged, irregular vibration will increase the probability of discharging impurities from the mesh of the screen 8. At the same time, due to the deflection around the load-bearing axis 4, the vibrating bucket 5 will generally move within the annular range of the rotation of the vibrating bucket 5 around the load-bearing axis 4, so that the thrown sand will still fall back into the vibrating bucket 5, and then the probability of the corresponding particle size passing through the screen 8 will be increased, thereby improving the efficiency of sand screening.

[0032] The hinge plate 7031, the V plate 704 and the cam plate 702 are all made of bronze, so that the hinge plate 7031, the V plate 704 and the cam plate 702 have better corrosion resistance, so that the device can be used for a long time in a humid environment, and at the same time, the deformation amplitude of the V plate 704 can be increased to increase the degree of irregular vibration of the vibration bucket 5. The connection between the hinge plate 7031, the V plate 704 and the cam plate 702 is hinged by a shoulder screw, and a ceramic layer is provided on the surface of the shoulder screw. The ceramic layer can resist the friction of the hinge plate 7031, the V plate 704 and the cam plate 702 to maintain the connection stability of the hinge plate 7031, the V plate 704 and the cam plate 702, thereby increasing the service life of the device.

[0033] A transmission assembly 3 is provided above the vibrating bucket 5 on the side away from the screen 8. The transmission assembly 3 is driven by the corresponding driving assembly 1. Specifically, the transmission assembly 3 includes a transmission shaft 302 rotatably provided on the carrier 2. A transmission belt 301 is transmitted on the transmission shaft 302. The transmission shaft 302 is driven to rotate by the driving assembly 1, and then the transmission belt 301 is driven to continuously circulate, and then the sand set on one side of the transmission belt 301 can be continuously transported to the vibrating bucket 5 for sand screening. The driving assembly 1 includes a driving motor 101 provided on one side of the carrier 2. The driving motor 101 is connected to the transmission shaft 302 and the end of the power shaft 701 passing through the carrier 2 through the transmission belt 102, so that the process of the vibrating bucket 5 deflecting and screening sand is synchronized with the process of feeding into the material, so as to facilitate the control and operation of the staff.

[0034] A debris discharge assembly 6 for discharging materials is provided at the bottom of the vibrating bucket 5. The debris discharge assembly 6 includes two winding drums 603 provided on both sides of the vibrating bucket 5 and four discharge ports 605 provided on the vibrating bucket 5. The four discharge ports 605 are distributed in a rectangular shape so that the vibrating bucket 5 forms a frame at the bottom. The two winding drums 603 are both rotatably connected with a winding shaft 604. The winding shaft 604 is provided with a barrier cloth 602. One side of the barrier cloth 602 is fixed on the winding shaft 604. The other side of the barrier cloth 602 is fixed with a clamping block 601. The clamping block 601 cooperates with the frame. It is used to locate the end of the barrier cloth 602. When it is necessary to discharge debris, the clamping block 601 can be removed from the center of the frame first, and then the two winding shafts 604 can be rotated to wind up the two barrier cloths 602. Then, multiple discharge ports 605 can be leaked out to discharge the large particles of sand and impurities remaining in the vibrating bucket 5 into the vibrating bucket 5 for processing. Specifically, the winding shaft 604 passes through the end of the winding drum 603 and is driven by the winding motor 606 fixed on the vibrating bucket 5, thereby assisting the staff to wind up the barrier cloth 602 to discharge the impurity materials.

[0035] <Example 2>

[0036] like Figure 6 As shown, the structure of this embodiment is basically the same as that of embodiment 1. The difference from embodiment 1 is that a counterweight block 705 is fixedly provided at the top corner of the V-plate 704. The counterweight block 705 can increase the weight at the top corner of the V-plate 704, thereby increasing the centrifugal force exerted on the top corner of the V-plate 704 when the V-plate 704 rotates with the support of the two hinged plates 7031 and the hinged groove 7032, thereby increasing the V-plate 704 driving the vibration bucket 5 and the irregularity of the deflection of sand and impurities in the vibration bucket 5, that is, further improving the efficiency of the vibration bucket 5 in screening sand.

[0037] <Example 3>

[0038] like Figure 7As shown, the basic structure of this embodiment is the same as that of embodiment 1 or embodiment 2. The difference from embodiment 1 or embodiment 2 is that a long groove 9 is provided at the connection between the vibrating bucket 5 and the load-bearing shaft 4. The long groove 9 enables the vibrating bucket 5 to slide on the load-bearing shaft 4 while deflecting around the load-bearing shaft 4, and then cooperates with the V-plate 704, the two hinged plates 7031 and the hinged groove 7032 to further increase the irregularity of the deflection of the vibrating bucket 5 around the load-bearing shaft 4, thereby further improving the efficiency of the vibrating bucket 5 in screening sand.

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
