Description

Technical Field

[0001] The utility model relates to the field of tobacco processing road wheels, in particular to a road wheel assembly for a driving belt conveyor used in the tobacco processing field. Background Art

[0002] The road wheel assembly of the traveling belt conveyor used in the tobacco processing field, also known as the supporting roller, is widely used in various tracked vehicles, such as military tracked vehicles, engineering machinery, agricultural machinery, etc. They play a key role in different application scenarios, ensuring that the vehicle can travel stably and efficiently. They play a vital role in tracked vehicles. The main function of the road wheel is to support the vehicle body to roll on the track ground section to ensure that the vehicle body can travel stably. The existing road wheel assembly of the traveling belt conveyor used in the tobacco processing field basically meets the needs of users, but there are still certain shortcomings. The road wheel assembly of the existing traveling belt conveyor used in the tobacco processing field has no margin for downward adjustment after the road wheel is worn, resulting in the road wheel having to be replaced with a new one once it is worn. However, the road wheels of the traveling belt conveyor used in the tobacco processing field are generally more easily worn, which makes it impossible for the traveling belt conveyor to maintain balance, which will affect the normal driving of the vehicle body. At this time, the only option is to remove the road wheel with worn surface and replace it with a new one. However, in fact, the worn road wheel has no structural damage. It is only the surface that is worn, resulting in a reduction in surface thickness, which in turn causes the road wheels on both sides of the traveling belt conveyor to have different heights. It is for this reason that the service life of the road wheels of the traveling belt conveyors used in tobacco processing is generally short and the economic cost is high.

[0003] In summary, there is an urgent need for a road wheel assembly for a crane belt conveyor used in the tobacco processing field that can adjust the height to adapt to wear conditions. Utility Model Content

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0048] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0049] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0050] The utility model embodiment provides a driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field, referring to Figure 1 and Figure 2 , including a hollow tube 1 and two movable mechanisms 2 that are symmetrical to each other and respectively arranged on the two outer walls of the hollow tube 1. The movable mechanism 2 includes an adapter plate 21 arranged on the outer wall of the hollow tube 1, and the adapter plate 21 is provided with two brackets 22 that are movably connected to it and parallel to each other, and a rotatable road wheel is provided between the two brackets 22. Through the above arrangement, after the road wheel 3 is worn, the bracket 22 can be adjusted downward along the adapter plate 21 to a certain distance so that the road wheel 3 is close to the ground again, which effectively increases the service life of the road wheel 3 and reduces the use cost of the road wheel 3. As a supplementary explanation, the hollow tube 1 usually spans the bottom of the traveling belt conveyor, and the movable mechanisms 2 are provided at both the left and right ends of the hollow tube 1. The movable mechanism 2 at one end of the hollow tube 1 can be as Figures 1 to 3 As shown, the moving mechanism 2 at the other end of the hollow tube 1 is also connected to Figure 1In other words, a hollow tube 1 carries a total of four moving mechanisms 2, with each pair of moving mechanisms 2 forming a pair, with a pair of moving mechanisms 2 mounted on each end of the hollow tube 1. If the road wheel 3 of any moving mechanism 2 is worn, it can be adjusted individually.

[0051] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figure 3 and Figure 4 The sidewall of the hollow tube 1 is provided with a first through-slot 11 extending along the height of the hollow tube 1. The adapter plate 21 is provided with a second through-slot 21.1 that matches the first through-slot 11. The bracket 22 is provided with an adjustment hole 22.1 on the side where it connects to the adapter plate 21. The bracket 22 also includes an adjustment screw 22.2 that is slidably connected to both the first through-slot 11 and the second through-slot 21.1. The fixing screw 26.1 passes through the first through-slot 11 and the second through-slot 21.1 and connects to the adjustment hole 22.1. For illustration, the height direction of the hollow tube 1 is also the adjustment direction of the road wheel 3. When the road wheel 3 wears, it typically loses contact with the ground, resulting in a gap between the road wheel 3 and the ground. This prevents the conveyor from operating stably and maintaining relative balance during movement. Therefore, when the road wheel 3 wears, it is necessary to adjust the position of the road wheel 3 downward so that it can return to contact with the ground. When adjusting, first remove the fixing screw 26.1, then gradually move the bracket 22 downward until the worn road wheel is close to the ground, and then reinsert the adjusting screw 22.2 through the first through slot 11 and the second through slot 21.1 and connect it to the adjusting hole 22.1, thereby recalibrating the height of the road wheel 3. Figure 2 As shown, one end of the adapter plate 21 is fixedly connected to the outer wall of the hollow tube 1 by screws. The positions of the first through slot 11 and the second through slot 21.1 are corresponding, and the slot sizes are usually quite appropriate. When adjusting the height of the road wheel 3, the brackets 22 on both sides of the road wheel 3 are usually adjusted synchronously to ensure that the road wheel 3 does not tilt.

[0052] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figure 1 、 2 and Figure 6The bracket 22 is provided with a bracket through-hole 22.3, and the road wheel 3 is provided with a road wheel through-hole 31. The bracket 22 also includes a rotating rod 23 that passes through the road wheel through-hole 31 and is rotatably connected to the road wheel 3. The two ends of the rotating rod 23 extend through the bracket through-holes 22.3 in the bracket 22 located on either side of the road wheel 3. For illustration, when the vehicle is moving, the road wheel 3 rotates about the rotating rod 23 and rotates in the same direction as the driving wheel of the driving belt conveyor.

[0053] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figures 1 to 3 and Figure 6 , the two ends of the rotating rod 23 are also provided with a limit plate 24 with a cross-sectional area larger than the cross-sectional area of ​​the bracket through hole 22.3. As an explanation, the limit plate 24 can ensure that the rotating rod 23 does not slip out of the bracket through hole 22.3, thereby ensuring safety during driving.

[0054] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figures 1 to 3 A first shielding plate 25 is provided on the outer wall of the hollow tube 1, perpendicular to the hollow tube 1. Below the first shielding plate 25, a fixed plate 26 is connected to the first shielding plate 25 and has an adjustable distance. The bottom of the fixed plate 26 is connected to the top of the brackets 22 located on both sides of the road wheels 3. For illustration, the first shielding plate 25 can block objects falling from the overhead conveyor, preventing them from damaging the road wheels 3. The fixed plate 26 can further secure the brackets 22 from the top, improving their stability.

[0055] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figures 1 to 3 and Figure 5 , further comprising a fixing screw 26.1 and a fixing nut 26.2; the fixing screw 26.1 sequentially passes through the first shielding plate 25 and the fixing plate 26 and is connected to the fixing nut 26.2. As an illustration, Figure 1 As described above, there is no gap between the first shielding plate 25 and the fixing plate 26. This situation mostly occurs when the road wheel 3 is not worn. When the road wheel 3 is worn, it is necessary to adjust the bracket 22 to move downward. At this time, a gap will be generated between the first shielding plate 25 and the fixing plate 26. Figure 5 As shown, when the first shielding plate 25 and the fixing plate 26 are to be connected, the fixing screws 26.1 are passed through the first shielding plate 25 and the fixing plate 26 from top to bottom, and then are tightened with the fixing nuts 26.2.

[0056] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figures 1 to 3 A second shielding plate 27 is provided on the end of the first shielding plate 25 away from the hollow tube 1 and extends toward the road wheel 3. As an illustration, the width of the second shielding plate 27 is greater than the width of the road wheel 3, and the second shielding plate 27 can block flying dust or gravel to prevent them from damaging the road wheel 3.

[0057] In the embodiment of the utility model, the driving belt conveyor road wheel assembly for the tobacco processing field used in the tobacco leaf redrying field is provided. Figures 1 to 3 , a clamping plate 28 is provided on the top of the hollow tube 1, and the clamping plate 28 extends toward the side wall of the hollow plate and is partially located above the first baffle plate 25. The clamping plate 28 located above the first baffle plate 25 is connected to the first baffle plate 25. As an illustration, the clamping plate 28 and the first baffle plate 25 can be connected by screws. When the road wheel 3 passes by an object of a certain height or passes by an object quickly, the road wheel 3 will be subjected to a large upward thrust in a short period of time. This thrust can easily cause the connection between the road wheel 3 and its associated components to collapse. Therefore, the clamping plate 28 can provide a downward pressure, thereby offsetting the upward thrust received by the road wheel 3 to a certain extent, so as to ensure the safety of the road wheel 3 when moving.

[0058] The present invention also provides a method for using a road wheel 3 for a driving belt conveyor, which includes at least the following steps:

[0059] 1) First, pass the rotating rod 23 through the bracket through-holes 22.3 on the two brackets 22 and the road wheel through-hole 31 on the road wheel 3 to connect the two brackets 22 and the road wheel 3;

[0060] 2) Adjust the height of the bracket 22 along the height direction of the adapter plate 22 so that the road wheel 3 can be close to the ground and maintain balance. During adjustment, the adjustment hole 22.1 should be located within the range of the first through slot 11 and the second through slot 21.1;

[0061] 3) At this height, insert the adjusting screw 22.2 through the first through slot 11 and the second through slot 21.1 and into the adjusting hole 22.1 and tighten it to complete the first fixation;

[0062] 4) Connect the first shielding plate 25 and the fixing plate 26 with the fixing screws 26.1 and the fixing nuts 26.2 to complete the secondary fixation;

[0063] 5) Install the pressing plate 28 onto the first shielding plate 25 using screws.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
