Description

Technical Field

[0001] The invention relates to the field of tobacco processing road wheels, in particular to a driving belt conveyor road wheel assembly 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 grounding 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 existing road wheel assembly of the 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 once being worn. Only a new road wheel can be replaced. However, the road wheels of the traveling belt conveyor used in the tobacco processing field are generally more easily worn, which makes the traveling belt conveyor unable to maintain balance, which will cause 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 conveyor belt to have different heights. It is for this reason that the service life of the road wheels of the conveyor belts used in tobacco processing is generally short and the economic cost is high.

[0003] In summary, there is an urgent need for a traveling belt conveyor road wheel assembly for use in the tobacco processing field that can adjust the height to adapt to wear conditions. Summary of the invention

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

[0050] The embodiment of the present invention provides a driving belt conveyor road wheel assembly for use in the tobacco processing field in the tobacco leaf redrying field, referring to Figure 1 and Figure 2 , including a hollow tube 1 and two movable mechanisms 2 which 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 which are movably connected thereto and parallel to each other, and a rotatable road wheel is arranged 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 by a certain distance to make the road wheel 3 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 1That is to say, a hollow tube 1 carries a total of four moving mechanisms 2, and every two moving mechanisms 2 form a pair, and a pair of moving mechanisms 2 is carried at the left and right ends of the hollow tube 1. No matter which moving mechanism 2 has a worn road wheel 3, it can be adjusted separately.

[0051] In the driving belt conveyor road wheel assembly used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to Figure 3 and Figure 4 , the side wall of the hollow tube 1 is provided with a first through slot 11 extending along the height direction of the hollow tube 1, and the adapter plate 21 is provided with a second through slot 21.1 matching the first through slot 11; the side where the bracket 22 is connected to the adapter plate 21 is provided with an adjustment hole 22.1; and also includes an adjustment screw 22.2, the adjustment screw 22.2 is slidably connected to the first through slot 11 and the second through slot 21.1, and the fixing screw 26.1 passes through the first through slot 11 and the second through slot 21.1 and is connected to the adjustment hole 22.1. As an illustration, the height direction of the hollow tube 1 is also the adjustment direction of the road wheel 3. When the road wheel 3 is worn, it is usually unable to get close to the ground, resulting in a gap between the road wheel 3 and the ground, so that the driving belt conveyor cannot run stably and cannot maintain relative balance during movement. Therefore, when the road wheel 3 is worn, it is necessary to adjust the position of the road wheel 3 downward so that the road wheel 3 can get close to the ground again. 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 re-insert 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 realizing the recalibration of the height of the road wheel 3. As a supplementary explanation, 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, and the positions of the first through slot 11 and the second through slot 21.1 are corresponding, and the sizes of the slots are usually quite corresponding. 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 driving belt conveyor road wheel assembly used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to 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; it also includes a rotating rod 23 that passes through the road wheel through hole 31 and is rotatably connected to the road wheel 3, and the two ends of the rotating rod 23 respectively pass through the bracket through holes 22.3 in the bracket 22 located on both sides of the road wheel 3. As an illustration, when the vehicle moves, the road wheel 3 rotates around the rotating rod 23 and keeps rotating in the same direction as the driving wheel of the driving belt conveyor.

[0053] In the road wheel assembly of the driving belt conveyor used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to 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 illustration, the limit plate 24 can ensure that the rotating rod 23 will not slip out of the bracket through hole 22.3, thereby ensuring the safety during driving.

[0054] In the road wheel assembly of the driving belt conveyor used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to Figures 1 to 3 , a first shielding plate 25 perpendicular to the hollow tube 1 is provided on the outer wall of the hollow tube 1, a fixing plate 26 connected to the first shielding plate 25 and adjustable in distance is provided below the first shielding plate 25, and the bottom of the fixing plate 26 is connected to the top of the bracket 22 located on both sides of the road wheel 3. As an illustration, the first shielding plate 25 can block objects falling from the driving belt conveyor to prevent them from damaging the road wheel 3. The fixing plate 26 can further fix the bracket 22 from the top, thereby improving the stability of the bracket 22.

[0055] In the road wheel assembly of the driving belt conveyor used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to 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 locked with the fixing nuts 26.2.

[0056] In the driving belt conveyor road wheel assembly used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to Figure 1 to Figure 3 A second shielding plate 27 extending toward the road wheel 3 is disposed on one end of the first shielding plate 25 away from the hollow tube 1. 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 shield flying dust or gravel to prevent it from damaging the road wheel 3.

[0057] In the driving belt conveyor road wheel assembly used in the tobacco processing field for the tobacco leaf redrying field provided by the embodiment of the present invention, refer to Figure 1 to Figure 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, and 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 with 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 relationship 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 embodiment of the present invention further provides a method for using a driving road wheel 3 for a driving belt conveyor, which at least includes 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 holes 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 keep balance. During the 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, the adjusting screw 22.2 is passed through the first through slot 11 and the second through slot 21.1 and inserted into the adjusting hole 22.1 and locked to complete the first fixation;

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

[0063] 5) Install the pressing plate 28 onto the top of the first shielding plate 25 by 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 substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
