The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] The present application relates to a vibrating screening device, which includes a screening component, and the screening component screens materials. Specifically, the screening component screens materials in a vibrating manner. The screening component screens ceramic balls from products and metal balls, and the products and metal balls are further screened in a subsequent process.

[0026] Specifically, the screening component includes a screening area 101 and a first drop area 102, the bottom plate of the screening area 101 is set as a screening plate, the screening area 101 is located above the first drop area 102, and the second drop area is set at the discharge end of the screening area 101. It can be understood that the screening area 101 screens the material in a vibrating manner so that part of the material falls into the first drop area 102, and the other part of the material is transported to the second drop area in a vibrating manner on the screening area 101. Further, the material falling into the first drop area 102 is the product and metal balls, which are transported to the next process, and the material in the second drop area is the ceramic balls to be removed by the screening component.

[0027] Combined with Figure 1 and attached Figure 2 The second material dropping area includes a material dropping guide groove 103, which is horizontally arranged at the outlet end of the screening area 101, so that all materials in the second material dropping area can enter the material dropping guide groove 103. Further, the second material dropping area includes a material dropping opening 104, which is located at one end of the material dropping guide groove 103, and the material dropping opening 104 is located at one side of the screening area 101 parallel to the length direction of the screening area 101, and the material in the material dropping guide groove 103 is discharged from the material dropping opening 104.

[0028] In some embodiments, the material drop guide 103 is arranged parallel to the width direction of the screening section 101. In other alternative embodiments, the material drop guide 103 is arranged obliquely parallel to the width direction of the screening section 101, so that the materials in the screening section 101 fall into the material drop guide 103 one after another.

[0029] As an embodiment, the bottom plate of the material drop guide 103 is inclined. Specifically, the material drop guide 103 is configured as a groove body with a concave shape at the discharge end of the screening area 101. One end of the bottom plate of the material drop guide 103 is higher than the other end, so that the material in the material drop guide 103 can roll along the inclined bottom plate to the lower end. Furthermore, the drop port 104 is located at the lower end of the bottom plate of the material drop guide 103 to facilitate the discharge of materials.

[0030] In some examples, the slope of the bottom plate of the blanking guide trough 103 is 3 to 6 degrees.

[0031] As an embodiment, the screening area 101 is provided with strip-shaped screen holes. Specifically, on the screen plate, the product and metal balls can fall through the strip-shaped screen holes, while the ceramic balls larger than the product and metal balls cannot fall through. Figure 2 The strip sieve holes are arranged in at least two groups, each group having at least one row of strip sieve holes in a direction parallel to the width of the screening area 101. Furthermore, the spacing between two adjacent groups of strip sieve holes in a direction parallel to the length of the screening area 101 gradually increases. It can be understood that the amount of material near the feeding end of the screening area 101 is large, so the spacing between the strip sieve holes in the front is small and densely distributed, so that most of the ceramic balls can be quickly screened out.

[0032] Furthermore, the screening area 101 is made by milling a hard aluminum alloy plate, which has stronger rigidity and a smoother surface than an etched plate, and is convenient for opening strip-shaped screening holes.

[0033] As an embodiment, the vibrating screening device includes a feed assembly, and the material is transported from the feed assembly to the screening assembly. Specifically, the feed assembly transports the material in a vibrating manner, and the material enters the screening area 101 from the feed assembly in a vibrating manner.

[0034] It can be understood that the feeding assembly includes a feeding area 201, which is located at the feeding end of the screening area 101, and the feeding area 201 conveys the material to the screening area 101 in a vibrating manner. On the other hand, during the vibration feeding process, the material can be spread and dispersed in the feeding area 201 for screening. Figure 3 The side of the feeding area 201 is provided with a side plate to prevent the material from falling, and a discharge end is left.

[0035] Furthermore, the vibrating screening device is provided with vibrators for the feeding component and the screening component respectively to form a split direct vibration effect. It should be noted that if the feeding component and the screening component share a vibrator, on the one hand, the overall weight of the vibrator is too large, the size is large, and the screening speed is slow and the screening effect is poor. On the other hand, it is inconvenient to disassemble and replace the screening area 101.

[0036] As an embodiment, the bottom plate surface of the feeding area 201 has at least two concave conveying grooves, and each conveying groove is arranged along a length direction parallel to the feeding area 201. Figure 3 The conveying troughs are arranged at intervals on the bottom plate surface of the feeding area 201. The conveying troughs extend in the feeding area 201 to the end close to the screening area 101, and a gap is formed so that the material in the conveying trough can be sent out from the feeding area 201.

[0037] Furthermore, the bottom plate in the feeding area 201 is configured to have at least two steps, so that the material can be transported layer by layer in the feeding area 201 .

[0038] As an embodiment, the feeding assembly includes a scraper 202, which is arranged on the upper side of the bottom plate of the feeding area 201, and a gap is left between the bottom of the scraper 202 and the upper side of the bottom plate of the feeding area 201. The scraper 202 is arranged in a width direction parallel to the feeding area 201, and the scraper 202 is used to scrape the material in the feeding area 201 flat.

[0039] It can be understood that, under the action of the scraper 202, the material on the feeding area 201 can be further spread and dispersed so that the material is evenly distributed. Figure 3When the bottom plate of the feeding area 201 is set in a stepped shape, the scraper 202 is located on the upper side of the highest level bottom plate.

[0040] Furthermore, an inclined guide surface is provided at the bottom of the scraper 202, and the distance between the guide surface and the bottom plate of the feeding area 201 gradually decreases along the length direction parallel to the feeding area 201, so as to form a gap that is first large and then small. In this case, the guide surface can be used to ensure that the material passes through the bottom of the scraper 202, and the scraper 202 can also facilitate the scraping of the material.

[0041] In some examples, the height of the scraper 202 relative to the bottom plate of the feeding area 201 is adjustable. Specifically, the side plate of the feeding area 201 is provided with a third support frame, the scraper 202 is connected to the third support frame by screws or bolts, and the scraper 202 is provided with a vertical waist-shaped hole to adjust the height of the scraper 202.

[0042] In some examples, the feeding assembly includes a fourth support frame, both ends of which are respectively connected to the side panels of the feeding area 201 , and a sensor is provided on the fourth support frame, and the sensor is used to detect whether there is material in the feeding area 201 .

[0043] As an implementation mode, the vibration screening device includes a hopper 301, and the hopper 301 is located above the feeding area 201. The material enters the feeding area 201 from the hopper 301, and the hopper 301 discharges the material in a vibrating manner.

[0044] Furthermore, the height of the hopper 301 is adjustable to adjust the distance between the outlet at the bottom of the hopper 301 and the feeding area 201. Figure 1 The vibration screening assembly includes a first lifting support assembly, the hopper 301 is connected to the first lifting support assembly, and the first lifting support assembly plays the role of supporting the hopper 301 and adjusting the height of the hopper 301. Figure 1 The top of the first lifting support assembly is connected to the hopper 301 through the first support frame.

[0045] Specifically, the first lifting support assembly includes at least two first lifting assemblies, and the first lifting assembly includes a telescopic cylinder. Alternatively, an alternative design is that the first lifting assembly lifts the hopper 301 in the form of a screw rod pair.

[0046] As an embodiment, at least one of the feed assembly and the screening assembly is height-adjustable.

[0047] In some examples, the heights of the feed assembly and the screening assembly are both adjustable. Specifically, the vibrating screening assembly includes a second lifting support assembly, the second lifting support assembly includes a support plate and at least two second lifting assemblies, the support plate is connected to the tops of the second lifting assemblies, and the feed assembly and the screening assembly are both arranged on the support plate. The second lifting assembly includes a telescopic cylinder. Alternatively, the alternative design is that the second lifting assembly lifts the feed assembly and the screening assembly in the form of a screw pair.

[0048] In some alternative examples, the vibrating screening assembly may also be designed so that the feed assembly and the screening assembly can adjust their heights separately. In this case, the vibrating screening assembly is configured with lifting support assemblies for the feed assembly and the screening assembly respectively.

[0049] In other alternative examples, the height of the feed assembly or the screening assembly is adjustable.
