It is widely used in various materials, different distances and diverse working environments, providing enterprises with strong material handling support.

[0003] In the process of conveying granular materials, it is often necessary to screen the materials according to specific particle size requirements. Especially in industries such as mining and sandstone, the grading of materials is particularly important in order to separate materials of different particle sizes to meet the fine requirements of subsequent processing or use. Therefore, in practical applications, conveyors are often used in conjunction with screening devices to achieve integrated material screening and conveying.

[0004] However, when screening materials, existing screening devices usually only focus on collecting the screened materials, while the materials that cannot be screened are often simply piled up and stored in the screening device. This approach has obvious defects: as the materials continue to accumulate, the capacity of the screening device will gradually decrease, and the screening speed of the new materials will gradually slow down, which may lead to a decrease in the screening effect. In addition, the materials stored in the screening device may be difficult to remove and clean due to accumulation and blockage, which not only increases the difficulty of maintenance, but also may affect the overall operating efficiency of the conveyor.

DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0025] like Figure 1-4 As shown, the screening device of the conveyor according to the embodiment of the utility model comprises an outer protection mechanism 10 , a screening assembly 20 , a material passing assembly 30 , a discharge cover shell 40 and a material receiving box 50 .

[0026] The outer protection mechanism 10 comprises an outer protection shell 101 and a material passing chute 102 , wherein the material passing chute 102 is provided on the outer protection shell 101 .

[0027] It should be noted that the outer protective shell 101 in this embodiment is connected to the conveyor, the material chute 102 is opened on the outer protective shell 101, and the material chute 102 is connected to the discharge port on the conveyor, so that the material on the conveyor falls into the outer protective shell 101 through the discharge port and the material chute 102.

[0028] Furthermore, the material chute 102 is provided with an inclined notch, so that the material can slide and fall smoothly into the outer protective shell 101.

[0029] The screening material assembly 20 is disposed on the outer protective shell 101 , and the screening material assembly 20 includes an outer cover shell 201 , a screening material component 202 and a driving mechanism 203 .

[0030] There are two groups of outer cover shells 201 , which are respectively arranged on the outer protective shell 101 , and the driving mechanism 203 is arranged on the outer cover shells 201 . Both ends of the screening component 202 are respectively rolled up on the two groups of driving mechanisms 203 .

[0031] It should be noted that the outer cover shell 201 is symmetrically arranged on the outer protective shell 101, and open slots are opened on both sides of the outer protective shell 101 for the screening assembly 20 to pass through. The driving mechanism 203 drives the screening assembly 20 to be rolled up and screens the material falling on the screening assembly 20.

[0032] Furthermore, the screening component 202 is a screen mesh, which is designed according to the size of the material to be screened, and meshes with different apertures are provided on the same set of screen meshes, so that the screening component 202 with different mesh apertures can be conveniently selected according to different needs.

[0033] The material passing assembly 30 is arranged on the outer protective shell 101 , the material discharging cover 40 is arranged on the outer protective shell 101 , and the material discharging cover 40 is arranged below the material passing assembly 30 , and the material receiving box 50 is movably arranged in the outer protective shell 101 .

[0034] It should be noted that the material passing assembly 30 can intercept the material. During the screening process, large particles accumulate and move upward, and then slide down from the material passing assembly 30 and fall into the discharge cover 40. The screened material falls into the receiving box 50, and finally the receiving box 50 is pulled out to remove the screened material.

[0035] Specifically, the material needs to be screened during the conveying process on the conveyor. The material slides from the conveyor to the material chute 102 to the outer protective shell 101, and the material falls on the screening component 20. The driving mechanism 203 is connected to the control switch and the power supply to drive the screening component 202 to roll and move. The material rolls on the screening component 202 for screening. The screened material falls into the receiving box 50, and the unscreened material accumulates and slides from the material passing component 30 to the unloading cover 40. The screened and unscreened materials are effectively screened and discharged to improve the screening efficiency.

[0036] In one embodiment of the present invention, Figure 2 As shown, the driving mechanism 203 includes a driving component 2031 , a rotating shaft 2032 , a driven shaft 2033 and a transmission component 2034 .

[0037] The driving component 2031 is arranged on the outer shell 201, the rotating shaft 2032 is arranged at the output end of the driving component 2031, and the rotating shaft 2032 is arranged in one outer shell 201. The driven shaft 2033 is rotatably arranged in the other outer shell 201, and the transmission component 2034 is connected to the driven shaft 2033 and the rotating shaft 2032 respectively.

[0038] It should be noted that the driving component 2031 is a servo motor, which is operated by controlling the switch and the power supply to drive the rotating shaft 2032 to rotate. The transmission component 2034 is a transmission chain or a conveyor belt. When the transmission component 2034 is a transmission chain, sprockets are respectively provided on the rotating shaft 2032 and the driven shaft 2033, and when the transmission component 2034 is a conveyor belt, rubber wheels with anti-skid patterns on the surface are respectively provided on the rotating shaft 2032 and the driven shaft 2033.

[0039] In one embodiment of the present invention, Figure 4 As shown, the material transfer assembly 30 includes a fixing seat 301 , a baffle 302 and a material baffle mechanism 303 .

[0040] The fixing seat 301 is disposed on the outer cover shell 201 , the baffle plate 302 is disposed on the fixing seat 301 , and the material blocking mechanism 303 is disposed on the fixing seat 301 .

[0041] It should be noted that the fixing seat 301 and the outer protective shell 101 described in this embodiment are an integrated structure, and the top of the baffle 302 is set to be chamfered. When the material accumulates to a certain height, it slides down from the baffle 302. During the sliding process, the material is limited by the material blocking mechanism 303 to prevent the material from jumping out.

[0042] In one embodiment of the present invention, Figure 4 As shown, the material blocking mechanism 303 includes a protective cover shell 3031 and a movable baffle 3032 .

[0043] The protective cover shell 3031 is disposed on the fixing seat 301 , and the movable baffle 3032 is pivotally connected to the protective cover shell 3031 .

[0044] It should be noted that the protective cover shell 3031 is provided with a through hole at the end surface connected to the baffle 302. The material slides down from the through hole onto the fixed seat 301. The movable baffle 3032 turns over to effectively intercept the material, slowing down the speed of the material when it slides down, so that the material slides down smoothly.

[0045] In one embodiment of the present invention, Figure 4 As shown, the fixing seat 301 includes two groups of inclined end surfaces, the bottom of one group of inclined end surfaces is located directly above the discharge cover shell 40 , and the bottom of the other group of inclined end surfaces is located directly above the material receiving box 50 .

[0046] It should be noted that the end faces of the fixing seat 301 located on both sides of the outer protective shell 101 are respectively provided with inclined end faces, which have a cushioning effect when the material slides down, and limit the direction of the material sliding down, so that the material can stably fall into the discharge cover shell 40 and the material receiving box 50.

[0047] In one embodiment of the present invention, Figure 1 As shown, the bottom of the inner cavity of the discharge cover shell 40 is set as an inclined bottom plate, and the inclined angle of the inclined bottom plate is 165°.

[0048] It should be noted that a conveyor or another material receiving box 50 is connected to the discharge port of the discharge cover 40, and the materials automatically slide down through the discharge cover 40 with an inclined bottom plate to prevent blockage.

[0049] In one embodiment of the present invention, Figure 1 As shown, two groups of support blocks are provided at the bottom of the inner cavity of the outer cover shell 201, the top walls of the two groups of support blocks are provided with limiting sliding grooves, and the bottom wall of the material receiving box 50 is provided with a limiting sliding block.

[0050] It should be noted that the material receiving box 50 slides in the outer protective shell 101 by the limited sliding of the limited sliding block in the limited sliding groove.

[0051] Furthermore, in order to be more convenient and labor-saving, the material receiving box 50 can be designed according to the weight of the material received, and a pulley and slide rail method can be adopted.

[0052] The specific operating steps of the screening device of the conveyor in the embodiment of the utility model are as follows: when the material is transported by the conveyor and needs to be screened, the material on the conveyor enters the outer protective shell 101 through the material chute 102, and the material falls on the screening component 202. The operating drive mechanism 203 drives the screening component 202 to reel up and screen the material. During the screening process, the material falls into the receiving box 50 or the unloading cover shell 40, and the screened material is discharged separately.

[0053] The steps of screening are as follows: the driving component 2031 is operated to drive the rotating shaft 2032 to rotate, and the driven shaft 2033 is driven to rotate through the transmission component 2034 during the rotation of the rotating shaft 2032, thereby driving the screening component 202 to roll up. During the rolling process of the screening component 202, the material rolls, and at this time, the small material sinks downward and is screened out and falls into the receiving box 50, while the large material cannot be screened out from the screening component 202, and then accumulates together, flips out from the baffle 302, slides through the fixed seat 301 and falls into the discharge cover 40. While the screening of the material is convenient, the screened material and the unscreened material are both convenient to discharge.

[0054] In summary, in the screening device of the conveyor of the embodiment of the utility model, the material slowly slides down in the screening device and is finely screened by the rolling screening component. The screened material and the unscreened material are separated and taken out, which effectively avoids the accumulation and blockage of the material. It not only facilitates the processing of the screened material, but also significantly improves the screening efficiency and the overall operation efficiency of the conveyor.

[0055] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
