Description

Technical Field

[0001] This utility model relates to the field of material screening technology, specifically a screening drum device. Background Technology

[0002] In many fields such as industrial production, mining, and agricultural processing, material screening is a crucial technological step. The purpose of screening is to effectively separate materials of different particle sizes to meet the stringent particle size requirements of subsequent production or processing processes. Screening drum devices, as a common type of screening equipment, are widely used in screening various materials due to their advantages such as simple structure, convenient operation, and large processing capacity.

[0003] However, existing screening drum devices still have some problems that urgently need to be solved in actual use. On the one hand, after the material enters the screening drum, due to the presence of lumps, agglomerates, or large particles in the material, these substances easily accumulate on the surface of the screen cylinder during the screening process, hindering the normal passage of the material, resulting in low screening efficiency, or even the inability to effectively screen the material. This not only affects the production schedule but also increases the energy consumption and maintenance costs of the equipment. On the other hand, during long-term operation, the screen holes of the screening drum device are easily clogged by material particles. When the screen holes are clogged, the material cannot pass through the screen holes smoothly, greatly reducing the screening effect and also shortening the service life of the equipment. Therefore, a separate drum device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening drum device, which has the advantages of improving screening quality and preventing screen hole clogging. It solves the problems of existing devices being prone to reduced screening quality due to material agglomeration and screen hole clogging affecting normal use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screening drum device includes a support frame and a screen cylinder disposed inside the support frame. The top of the support frame is provided with auxiliary components for assisting the screen cylinder in screening materials.

[0007] The auxiliary component includes a motor fixedly connected to the top of the support frame. The output shaft of the motor is fixedly connected to a transmission rod. The left end of the transmission rod is fixedly connected to a transmission wheel. The outer surface of the transmission wheel is connected to a transmission belt. The bottom end of the transmission belt is connected to a driven wheel. A driven rod is fixedly connected to the inner side of the center of the driven wheel. A dredging component is provided at the left end of the driven rod.

[0008] Furthermore, the right end of the driven rod penetrates the left side wall of the support frame and extends to the inside of the support frame to be fixedly connected to the screen cylinder.

[0009] Furthermore, brackets are fixedly connected to both the left and right sides of the inner top wall of the support frame, the left end of the screen cylinder is rotatably connected to the inside of the left bracket, and the right end of the screen cylinder is rotatably connected to the inside of the right bracket.

[0010] Furthermore, a fixing rod is fixedly connected to the inner right side wall of the support frame, and a dispersing blade is fixedly connected to the outer side of the fixing rod.

[0011] Furthermore, a rotating hole adapted to the fixing rod is provided on the right side of the inner side of the screen cylinder, and the screen cylinder is rotatably connected to the fixing rod through the rotating hole.

[0012] Furthermore, the unblocking assembly includes a first bevel gear fixedly connected to the left end of the driven rod, a second bevel gear meshing with the bottom of the first bevel gear, a connecting rod fixedly connected to the inner side of the center of the second bevel gear, a contact wheel fixedly connected to the outer side of the connecting rod, a push plate contacting the right side of the contact wheel, an elastic support and a connecting plate fixedly connected to the right side of the push plate, and unblocking brush bristles fixedly connected to the top of the connecting plate, the unblocking brush bristles contacting the screen cylinder.

[0013] Furthermore, a support plate is rotatably connected to the bottom end of the connecting rod, and the support plate is fixedly connected to the left side wall of the support frame. A sliding opening adapted to the connecting plate is provided on the left side of the inner side of the support frame.

[0014] Furthermore, there are four elastic support members, and the four elastic support members are respectively arranged at the four corners of the right side of the push plate, and the right side of the elastic support member is fixedly connected to the support frame.

[0015] Compared with the prior art, the present invention provides a screening drum device, which has the following beneficial effects:

[0016] This screening drum device, when the screen cylinder rotates, allows the dispersing blades to fully contact the material entering the screen cylinder, applying external force to break up lumps and agglomerates, making the material looser. Loose material passes through the screen holes more easily, thus greatly improving screening efficiency, reducing material accumulation and clogging within the screen cylinder, and ensuring the stability and consistency of screening quality. Furthermore, as the driven rod drives the screen cylinder to rotate, the meshing of the first and second bevel gears causes the connecting rod and contact wheel to rotate accordingly. The contact wheel periodically pushes the push plate, which reciprocates under the action of the elastic support, thereby driving the connecting plate and the unblocking brush to reciprocate on the surface of the screen cylinder. The unblocking brush contacts the screen cylinder, promptly removing material particles clogging the screen holes and preventing clogging. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 3 The screening drum device in this embodiment includes a support frame 1 and a screen cylinder 2 disposed inside the support frame 1. The top of the support frame 1 is provided with an auxiliary component for assisting the screen cylinder 2 in screening materials.

[0023] Please see Figure 1 In this embodiment, the auxiliary component includes a motor 3 fixedly connected to the top of the support frame 1. The output shaft of the motor 3 is fixedly connected to a transmission rod 4. The left end of the transmission rod 4 is fixedly connected to a transmission wheel 5. The outer surface of the transmission wheel 5 is connected to a transmission belt 6. The bottom end of the transmission belt 6 is connected to a driven wheel 7. The inner side of the center of the driven wheel 7 is fixedly connected to a driven rod 8. The left end of the driven rod 8 is provided with a dredging component.

[0024] Specifically, the right end of the driven rod 8 passes through the left side wall of the support frame 1 and extends to the inside of the support frame 1 to be fixedly connected to the screen cylinder 2.

[0025] It should be noted that when the motor 3 starts, the power is transmitted to the driven rod 8 through the transmission rod 4, transmission wheel 5, transmission belt 6 and driven wheel 7, thereby enabling the screen cylinder 2 to obtain the power to rotate and realize the normal screening operation of the screen cylinder 2.

[0026] Specifically, brackets 9 are fixedly connected to both the left and right sides of the inner top wall of the support frame 1. The left end of the screen cylinder 2 is rotatably connected to the inside of the left bracket 9, and the right end of the screen cylinder 2 is rotatably connected to the inside of the right bracket 9.

[0027] It should be noted that the bracket 9 provides stable support and a base for rotation for the screen cylinder 2, enabling the screen cylinder 2 to remain stable during rotation.

[0028] Specifically, a fixing rod 10 is fixedly connected to the inner right side wall of the support frame 1, and a dispersing leaf 11 is fixedly connected to the outer side of the fixing rod 10.

[0029] It should be noted that during the rotation of the screen cylinder 2, the dispersing blades 11 can fully contact the material entering the screen cylinder 2 and disperse the material. When the material passes through the dispersing blades 11, the dispersing blades 11 will apply external force to the material, causing the lumps or agglomerates in the material to be broken, thereby making the material more loose, which is convenient for subsequent screening operations and improves screening efficiency and quality.

[0030] Specifically, a rotating hole adapted to the fixed rod 10 is provided on the right side of the inner side of the sieve cylinder 2, and the sieve cylinder 2 is rotatably connected to the fixed rod 10 through the rotating hole.

[0031] Specifically, the unblocking assembly includes a first bevel gear 12 fixedly connected to the left end of the driven rod 8, a second bevel gear 13 meshing with the bottom of the first bevel gear 12, a connecting rod 14 fixedly connected to the inner side of the center of the second bevel gear 13, a contact wheel 15 fixedly connected to the outer side of the connecting rod 14, a push plate 16 contacting the right side of the contact wheel 15, an elastic support 17 and a connecting plate 18 fixedly connected to the right side of the push plate 16, and an unblocking brush 19 fixedly connected to the top of the connecting plate 18, the unblocking brush 19 contacting the screen cylinder 2.

[0032] It should be noted that during the rotation of the contact wheel 15, it will periodically push the push plate 16. Under the action of the elastic support member 17, the push plate 16 can reciprocate, thereby driving the connecting plate 18 and the unblocking brush 19 to reciprocate on the surface of the screen cylinder 2, unblocking the screen holes of the screen cylinder 2 and preventing the material from clogging the screen holes.

[0033] Specifically, the bottom end of the connecting rod 14 is rotatably connected to a support plate 20, and the support plate 20 is fixedly connected to the left side wall of the support frame 1. A sliding opening adapted to the connecting plate 18 is opened on the left side of the inner side of the support frame 1.

[0034] It should be noted that the sliding opening provides space for the reciprocating motion of the connecting plate 18.

[0035] Specifically, there are four elastic support members 17, and the four elastic support members 17 are respectively arranged at the four corners of the right side of the push plate 16, and the right side of the elastic support member 17 is fixedly connected to the support frame 1.

[0036] The working principle of the above embodiments is as follows:

[0037] When motor 3 is turned on, its output shaft begins to rotate, providing initial power for the entire screening process. The output shaft of motor 3 drives the transmission rod 4 to rotate, and the transmission wheel 5, which is fixedly connected to the left end of the transmission rod 4, rotates synchronously. The transmission wheel 5 drives the driven wheel 7 to rotate through the transmission belt 6. The driven rod 8, which is fixedly connected to the inner side of the center of the driven wheel 7, begins to rotate. Since the right end of the driven rod 8 passes through the left side wall of the support frame 1 and extends to the inner side of the support frame 1 and is fixedly connected to the screen cylinder 2, the screen cylinder 2 begins to rotate around the fixed rod 10 under the drive of the driven rod 8, thereby screening the material. During this process, the dispersing blade 11 applies external force to the material, causing the lumps or agglomerates in the material to be broken up and become looser, which facilitates subsequent screening operations.

[0038] As the driven rod 8 rotates, the first bevel gear 12 fixedly connected to the left end of the driven rod 8 also rotates. Since the first bevel gear 12 meshes with the second bevel gear 13, the second bevel gear 13 begins to rotate and drives the connecting rod 14 fixedly connected to its inner center to rotate. The contact wheel 15 fixedly connected to the outer side of the connecting rod 14 rotates synchronously with the connecting rod 14. During the rotation, the contact wheel 15 periodically pushes the push plate 16, causing the push plate 16 to move to the right. During the movement to the right, the push plate 16 compresses the elastic support member 17 fixedly connected to its right side. When the contact wheel 15 leaves the push plate 16, the elastic support member 17 releases its elastic potential energy, pushing the push plate 16 to move to the left and return to its initial position. During the reciprocating motion, the push plate 16 drives the connecting plate 18 fixedly connected to its right side and the unblocking brush 19 fixedly connected to the top of the connecting plate 18 to reciprocate on the surface of the screen cylinder 2. The unblocking brush 19 contacts the screen cylinder 2 and can promptly remove the material particles blocked in the screen holes, preventing the screen holes from becoming clogged.
