Description

Technical Field

[0001] The utility model relates to the technical field of drum screens, and specifically relates to a limit wheel device. Background Art

[0002] The drum screen is a kind of machinery widely used in the sorting technology. It controls sorting by the particle size. The sorting accuracy is high. The cylinder of the drum screen is generally divided into several sections, which can be determined according to specific situations. The sieve holes are arranged from small to large, and the aperture of the sieve holes on each section is the same. During the use of the drum screen, a limit wheel device is needed to limit the movement of the drum.

[0003] For example, the utility model with the application number CN202023333206.6 discloses a limit wheel structure for a mud treatment drum screen. The limit wheel of this utility model is installed on both sides of the same side of the drum screen. The limit wheel limits and adjusts the drum screen in two angles of the axial direction and the radial direction to ensure that the drum screen does not shift during rotation and always maintains a relative position of 90 degrees with the external frame, so as to protect the service life of the drum screen and its rubber driving rollers and reduce the damage of the drum screen due to some unexpected situations during the operation process. However, when this kind of device is actually used, the position of the drum screen is adjusted by the stretching and contraction of the spring, and the spring is prone to vibration under external force, resulting in relatively general overall stability of the device during limiting.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a limit wheel device is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a limit wheel device to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A limit wheel device includes a roller and an adjustment component. A connecting shaft is arranged inside the roller, and brackets are rotatably connected to both ends of the connecting shaft. The adjustment component is arranged outside the brackets. The adjustment component includes a chute, a slider, a screw, a fixed seat and a positioning hole. A chute is opened on the outside of the brackets, and a slider is arranged inside the chute. One end of the slider is rotatably connected to a screw, and the middle outside of the screw is threadedly connected to a fixed seat, and a positioning hole is opened at the bottom of the fixed seat. A stability component is arranged outside the fixed seat.

[0007] Further, the brackets are U-shaped, and the slider is slidably connected to the brackets through the chute.

[0008] Further, the slider is isosceles trapezoidal, and the number of sliders is two.

[0009] Further, the stabilizing component includes a toothed ring, a toothed sleeve, and a gear. The toothed sleeve is sleeved outside the toothed ring, and the gear is slidably connected inside the toothed sleeve.

[0010] Further, the toothed ring is fixedly connected to the fixed seat, and the fixed seat is L-shaped.

[0011] Further, the outer shape of the gear is substantially the same as the outer shape of the toothed ring, and the gear is fixedly connected to the screw.

[0012] Further, the stabilizing component further includes a toggle block and a magnet. The toggle block is fixed to the outer side of one end of the toothed sleeve, and the magnet is fixed to the other end of the toothed sleeve.

[0013] Further, the magnet is annular, and the magnet is magnetically connected to the fixed seat.

[0014] The utility model provides a limit wheel device, which has the following beneficial effects:

[0015] 1. Through the setting of the adjusting component of the utility model, after the fixed seat is installed on the external mounting bracket and the position of the roller support needs to be adjusted, only by rotating the screw on one side can the bracket be driven to move through the slider. At this time, the slider on the other side can slide in the chute, so there will be no movement interference. Similarly, the screw on the other side can also be rotated to adjust the position of the roller, so that the roller can move along the axial or radial direction of the sieve cylinder, thereby improving the fitting degree between the limit wheel and the limit ring on the sieve cylinder during installation, and the roller can also be kept stable after adjustment.

[0016] 2. Through the equipment of the stabilizing component of the utility model, during adjustment, first pull the toothed sleeve through the toggle block to separate it from the toothed ring. Subsequently, when rotating, the force application lever arm can be extended through the toggle block, so as to conveniently drive the screw to rotate through the toothed sleeve and the gear, making the adjustment more convenient. And after adjustment, push the toothed sleeve and sleeve it outside the toothed ring. At this time, the magnet can adsorb the iron fixed seat to prevent it from falling off, so that the rotation of the screw can be restricted through the toothed sleeve and the gear, avoiding the self-rotation of the screw due to external vibration, and further improving the stability of the limit wheel device during use.

[0021] The following further describes in detail the implementation mode of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 and Figure 2 shown, a limit wheel device includes a roller 1 and an adjusting component 4. A connecting shaft 2 is arranged inside the roller 1, and both ends of the connecting shaft 2 are rotatably connected to a bracket 3. The adjusting component 4 is arranged outside the bracket 3. The adjusting component 4 includes a chute 401, a slide block 402, a screw 403, a fixed seat 404 and a positioning hole 405. A chute 401 is opened on the outside of the bracket 3, and a slide block 402 is arranged inside the chute 401. One end of the slide block 402 is rotatably connected to a screw 403, and the middle outside of the screw 403 is threadedly connected to a fixed seat 404. And a positioning hole 405 is opened at the bottom of the fixed seat 404. The fixed seat 404 is installed on an external mounting rack through a bolt and the positioning hole 405. The bracket 3 is U-shaped, and the slide block 402 is slidably connected to the bracket 3 through the chute 401. The slide block 402 is isosceles trapezoid, and the number of the slide blocks 402 is two. Rotating the screw 403 on one side can drive the bracket 3 to move through the slide block 402. At this time, the slide block 402 on the other side can slide in the chute 401. Therefore, there will be no movement interference. Similarly, the screw 403 on the other side can also be rotated to adjust the position of the roller 1, so that the roller 1 can move along the axial or radial direction of the sieve cylinder, thereby improving the fitting degree between the limit wheel and the limit ring on the sieve cylinder during installation.

[0023] As Figure 1 and Figure 3As shown, a stabilizing component 5 is arranged on the outer side of the fixing seat 404, and the stabilizing component 5 includes a gear ring 501, a gear sleeve 502 and a gear 503. The outer side of the gear ring 501 is sleeved with the gear sleeve 502, and the gear 503 is slidably connected inside the gear sleeve 502. The gear ring 501 is fixedly connected to the fixing seat 404, and the fixing seat 404 is L-shaped. The fixing seat 404 will limit the rotation of the gear ring 501. The outer shape of the gear 503 is basically the same as the outer shape of the gear ring 501, and the gear 503 is fixedly connected to the screw 403. By limiting the rotation of the gear 503, the rotation of the screw 403 can be avoided. The stabilizing component 5 also includes a toggle block 504 and a magnet 505. A toggle block is fixed on the outer side of one end of the gear sleeve 502. The gear sleeve 502 is pulled by the toggle block 504 to separate it from the gear ring 501. During subsequent rotation, the toggle block 504 can extend the force arm, thereby facilitating the rotation of the screw 403 through the gear sleeve 502 and the gear 503, making the adjustment more convenient. The magnet 505 is annular and is magnetically connected to the fixing seat 404. After adjustment, the gear sleeve 502 is pushed and put on the outside of the gear ring 501. At this time, the magnet 505 can absorb the iron fixing seat 404 to prevent it from falling off, thereby limiting the rotation of the screw 403 through the gear sleeve 502 and the gear 503 to prevent the screw 403 from rotating due to external vibration.

[0024] In summary, when the limiting wheel device is used, firstly according to Figure 1 , Figure 2 and Figure 3 In the structure shown in the figure, the fixing seat 404 is first installed on the external mounting frame through the bolts and the positioning holes 405. Then, when the position of the roller 1 support needs to be adjusted, the gear sleeve 502 is first pulled by the toggle block 504 to separate it from the gear ring 501. When it is subsequently rotated, the screw 403 is driven to rotate through the gear sleeve 502 and the gear 503. Then, by rotating the screw 403 on one side, the bracket 3 can be driven to move through the slider 402. At this time, the slider 402 on the other side can slide in the slide groove 401. Similarly, the screw rod 403 on the other side can be rotated to adjust the position of the roller 1, so that the roller 1 can move along the axial or radial direction of the screen drum, thereby improving the fit between the limiting wheel and the upper limiting ring of the screen drum during installation. Finally, after adjustment, the gear sleeve 502 is pushed and sleeved on the outside of the gear ring 501. At this time, the magnet 505 can absorb the iron fixing seat 404, so that the rotation of the screw rod 403 can be limited by the gear sleeve 502 and the gear 503, further improving the stability of the limiting wheel device during use.
