Description

Technical Field

[0001] The utility model belongs to the field of drum screens, in particular to a stirring drum screen device. Background Art

[0002] The traditional drum device is installed on the frame at an angle. The motor is connected to the drum device through a coupling via a reducer to drive the drum device to rotate around its axis. When the material enters the drum device, the material on the screen surface is turned over and rolled due to the inclination and rotation of the drum device. Qualified small-sized materials are discharged through the discharge port at the bottom of the rear end of the drum, and unqualified large-sized materials are discharged through the discharge port at the tail of the drum. The patent with the authorization announcement number CN219836777U: "Stirring Roller Screen Device" discloses a device for screening materials using a drum screen. However, when the device is in use, the outermost material is not easily transported upward with the conveying mechanism, and will still slide to the bottom, resulting in poor upward conveying effect, resulting in reduced screening efficiency. Therefore, we have designed a stirring roller screen device that can increase the material conveying stroke. Utility Model Content

DETAILED DESCRIPTION

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A stirring roller screen device, such as Figure 1 、 2 As shown, it includes a base 1, a horizontal tube 2 with an inclined arrangement is fixedly installed on the base 1, one end of the horizontal tube 2 is open and the other end is closed, a feed port 3 is provided on the horizontal tube 2, a first screen tube 4 is rotatably installed on the horizontal tube 2, a plurality of first through holes 5 are provided on the first screen tube 4, a driving mechanism for driving the first screen tube 4 to rotate is provided on the horizontal tube 2, a rotating shaft 6 is rotatably installed on the horizontal tube 2, the horizontal tube 2, the first screen tube 4 and the rotating shaft 6 are coaxially arranged, a first motor 7 for driving the rotating shaft 6 to rotate is fixed on the horizontal tube 2, and the rotating shaft of the first motor 7 is rotatably installed on the horizontal tube 2 through a bearing The reserved hole opened on the horizontal tube 2 is coaxially fixedly connected to the rotating shaft 6. Several first baffles 8 are fixedly installed on the first screen tube 4. The first baffles 8 are evenly distributed along the circumference of the axis of the rotating shaft 6. The outer periphery of the rotating shaft 6 is fixedly installed with spiral blades 9. The outer periphery of the spiral blades 9 is slidably matched with a semicircular second screen tube 10. The second screen tube 10 and the rotating shaft 6 are coaxially arranged. The second screen tube 10 is fixedly installed on the horizontal tube 2. Several second through holes 11 are opened on the second screen tube 10. A first material receiving box 12 and a second material receiving box 13 are fixedly provided on the base 1. The utility model has a simple structure and an ingenious design. The first baffle 8 can increase the moving stroke of the material and realize repeated screening. At the same time, the spiral blades 9 can transport large-sized materials upward. Small-sized materials that meet the requirements are screened out through the second through holes 11 and the first through holes 5 in turn, meeting market requirements and being suitable for promotion. When using the present invention, the material to be screened is first conveyed to the feed port 3, and the first screen tube 4 and the first baffle 8 are driven to rotate by the driving mechanism. The rotating shaft of the first motor 7 drives the rotating shaft 6 and the spiral blade 9 to rotate. The rotation of the first baffle 8 can crush the material and drive the material to rotate, thereby increasing the stroke of the material and making the material screened repeatedly. The small-sized material directly passes through the first through hole 5 to reach the first receiving box 12. When the large-sized material is driven to the top of the first screen tube 4, it falls freely under the action of its own gravity and collides with the spiral blade 9, which can break the large material clumps into small-sized materials. The small-sized materials pass through the second through hole 11 and the first through hole 5 in turn and fall into the first receiving box 12. The materials that cannot be crushed continue to be conveyed to the left and are stirred and crushed by the first baffle 8 in the first screen tube 4. This cycle repeats and the materials that cannot be crushed eventually fall into the second receiving box 13.

[0017] Specifically, as shown in the figure, the drive mechanism of this embodiment includes a second motor 20, which is fixedly mounted on the transverse tube 2. A coaxial first gear 21 is fixedly mounted on the rotating shaft of the second motor 20. A gear ring 22 is meshed with one side of the first gear 21. The gear ring 22 is fixedly mounted on the outer periphery of the first screen tube 4 and is coaxially arranged. Rotation of the rotating shaft of the second motor 20 drives rotation of the first gear 21, which in turn drives rotation of the gear ring 22 and the first screen tube 4.

[0018] Specifically, as shown in the figure, the cross tube 2 described in this embodiment is fixedly mounted on the base 1 via a connecting rod. An annular groove 30 is formed at one end of the cross tube 2. An annular flange 31 is fixedly mounted at one end of the first screen tube 4. The annular flange 31 is slidably mounted within the annular groove 30. The other end of the first screen tube 4 is rotatably mounted on the base 1 via a first bearing seat 32. The outer periphery of the first screen tube 4 is fixedly connected to the inner periphery of the first bearing seat 32, and the outer periphery of the first bearing seat 32 is fixedly mounted on the base 1. When the first screen tube 4 rotates, the annular flange 31 can slide within the annular groove 30. The provision of the first bearing seat 32 is conducive to the rotational stability of the first screen tube 4.

[0019] Furthermore, as shown in the figure, one end of the rotating shaft 6 of this embodiment extends out of the first screen tube 4 and is rotatably mounted on the base 1 via a second bearing seat 40. The outer periphery of the rotating shaft 6 is fixedly connected to the inner periphery of the second bearing seat 40, and the outer periphery of the second bearing seat 40 is fixedly mounted on the base 1. One end of the second screen tube 10 is fixedly mounted on the cross tube 2 via a plurality of first connecting rods, and the other end of the second screen tube 10 is fixedly mounted on the outer periphery of the second bearing seat 40 via a plurality of second connecting rods. The provision of the second bearing seat 40 is conducive to the stability of the rotation of the rotating shaft 6 and the stability of the second screen tube 10.

[0020] Furthermore, as shown in the figure, in this embodiment, a plurality of second baffles 50 are fixedly mounted on the outer periphery of the second screen tube 10. The second baffles 50 are evenly distributed around the circumference of the second screen tube 10. When the second baffles 50 and the first baffle 8 are close to each other, the shear force between them can be used to crush larger materials, allowing them to be screened out of the first through hole 5 more quickly, facilitating use.

[0021] Furthermore, as shown in the figure, the feed port 3 of this embodiment is connected with a feed pipe 60, which is fixedly mounted on the transverse pipe 2 and has a funnel 61 fixedly mounted on the feed pipe 60. It is easier to transport materials into the feed port 3 through the funnel 61 and is convenient to use.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
