When the trolley moves on the track 100, the roller 23 and the limiting wheel 24 respectively roll with the vertically connected transverse plate 101 and the vertical plate 102, which can ensure the stability of the trolley operation. In addition, the structure of the track 100 and the chain plate structure 2 is simple and compact, which is conducive to reducing the cost of the sorting machine.

[0043] Optionally, see Figure 2The first trolley 200 and the second trolley 300 also include a conveying assembly 3, which is used to support the articles and convey the articles to both sides of the track 100. The conveying assembly 3 can be a conveying roller, a belt conveying assembly or a chain conveying assembly. Specifically, in this embodiment, an exemplary scheme of the conveying assembly 3 using a belt conveying assembly is given, and the conveying assembly 3 includes an electric roller 31, a driven roller 32 and a conveyor belt 33. The electric roller 31 and the driven roller 32 are relatively parallel and spaced apart and arranged on the vehicle body 1. The conveyor belt 33 is sleeved on the electric roller 31 and the driven roller 32. The electric roller 31 can rotate forward and reverse, and the electric roller 31 drives the conveyor belt 33 to move when rotating, so as to convey the articles to both sides of the track 100. Preferably, both sides of the track 100 of the sorting machine are also provided with a chute (not shown in the drawings) and a storage box (not shown in the drawings), each chute is inclined, the storage box is arranged at the lower end of the chute, and the high end of the chute is used to receive the items transported by the first trolley 200 or the second trolley 300, and the items can automatically slide along the chute into the storage box under their own gravity.

[0044] Optionally, see Figure 1 and Figure 2 The track 100 includes two horizontal plates 101 and two vertical plates 102. The two vertical plates 102 are arranged in a horizontal direction (such as Figure 1 The two horizontal plates 101 are respectively connected vertically to the two vertical plates 102, and each horizontal plate 101 is located between the two vertical plates 102. The first trolley 200 and the second trolley 300 both include two chain plate structures 2, and the base frames 21 of the two chain plate structures 2 are respectively fixedly connected to the two ends of the vehicle body 1 in the horizontal direction, and the rollers 23 of the two chain plate structures 2 are respectively rollingly matched with the two horizontal plates 101, and the limiting wheels 24 of the two chain plate structures 2 are respectively rollingly matched with the two vertical plates 102. With such an arrangement, multiple trolleys can be supported by the two ends of the two horizontal plates 101, and multiple trolleys can be limited by the two ends of the two vertical plates 102 in the horizontal direction, and the stability of the multiple trolleys during movement can be further improved.

[0045] Optionally, the track 100 is arranged in a ring shape as a whole, and a plurality of trolleys are arranged in sequence along the ring track 100, and any adjacent trolleys are hingedly connected by connecting members 400. Such an arrangement enables the sorting machine to achieve cyclic sorting, thereby improving the sorting efficiency.

[0046] Optionally, the first plate 211 and the third plate 213 are arranged in parallel and at intervals, the second plate 212 is vertically connected to the first plate 211 and the third plate 213 respectively, and the first plate 211, the second plate 212 and the third plate 213 are integrally formed. Specifically, the first plate 211, the second plate 212 and the third plate 213 can be integrally formed by sheet metal stamping and bending processes, the processing technology is simple, and it is beneficial to reduce production costs.

[0047] Optionally, see Figures 5 to 7 The first plate 211 is provided with a notch 216, the second plate 212 includes a convex plate 217 extending from the notch 216 to the outside of the first plate 211, and the limiting wheel 24 is rotatably mounted on the convex plate 217. Specifically, the convex plate 217 is flush with the second plate 212. If the convex plate 217 is bent to be flush with the first plate 211, the convex plate 217 can completely or partially close the notch 216, so that the convex plate 217 can be integrally formed with the first plate 211, the second plate 212 and the third plate 213 through sheet metal stamping and bending processes. In other embodiments, the convex plate 217 can also be welded to the second plate 212.

[0048] As an alternative solution, the base frame 21 further includes a support plate vertically arranged with respect to the first plate 211 , the support plate is located at a first side of the first plate 211 away from the second plate 212 , and the limiting wheel 24 is rotatably mounted on the support plate.

[0049] Optionally, see Figure 7 , the convex plate 217 is provided with a through hole 218; the chain plate structure 2 also includes a sleeve 25 and a fastener 26, the limiting wheel 24 is sleeved on the sleeve 25 and can rotate around the axis of the sleeve 25, the sleeve 25 is provided with a threaded hole, and the fastener 26 passes through the through hole 218 and is threadedly connected to the threaded hole. Such a configuration facilitates the removal and installation of the limiting wheel 24. Preferably, the fastener 26 is a screw.

[0050] Optionally, see Figure 5 and Figure 6 Part of the limiting wheel 24 extends from the notch 216 to the inner side of the first plate 211. This arrangement can make the chain plate structure 2 more compact.

[0051] Optionally, see Figure 6 and Figure 7The limiting wheel 24 is the first bearing, and the inner ring of the first bearing is fixedly sleeved on the sleeve 25; the chain plate structure 2 also includes a first spacer 271, which is sleeved on the sleeve 25 and located between the first bearing and the convex plate 217. The outer diameter of the first spacer 271 is smaller than the outer diameter of the inner ring of the first bearing. In this way, on the one hand, the limiting wheel 24 is set as the first bearing, so that the resistance of the limiting wheel 24 when rotating is small, and the outer ring of the first bearing can rotate freely around the axis of the sleeve 25 relative to the inner ring of the first bearing, so that the limiting wheel 24 and the vertical plate 102 can roll more smoothly; on the other hand, the first spacer 271 is set between the first bearing and the convex plate 217, which can prevent the outer ring of the first bearing from contacting the convex plate 217 or the first spacer 271 when rotating relative to the inner ring. At the same time, the outer diameter of the first spacer 271 is smaller than the outer diameter of the inner ring of the first bearing, ensuring that the outer ring of the first bearing and the first spacer 271 have a smaller contact area, thereby reducing the sliding friction resistance between the two, so that the outer ring of the first bearing can rotate smoothly, and further improve the smoothness of the rolling cooperation between the limiting wheel 24 and the vertical plate 102. Of course, in other embodiments, a rotating shaft is fixedly set on the convex plate 217, and the limiting wheel 24 is rotatably sleeved on the rotating shaft.

[0052] Optionally, see Figure 3 , the chain plate structure 2 also includes a first nut 281; the connecting member 400 is a rod end joint bearing, the inner ring of the rod end joint bearing is fixedly sleeved with the support shaft 22 of the chain plate structure 2 of the first trolley 200, and is located between the first plate 211 and the third plate 213, and the screw of the rod end joint bearing is plugged into the base frame 21 of the chain plate structure 2 of the second trolley 300 and is threadedly connected with the first nut 281. In this way, the outer ring of the rod end joint bearing can rotate smoothly around the axis of the support shaft 22 relative to the inner ring of the rod end joint bearing, and the resistance to rotation is small, and the effect of the first trolley 200 and the second trolley 300 being hinged is achieved, so that when one of the first trolley 200 and the second trolley 300 is turning, the other of the first trolley 200 and the second trolley 300 will not interfere.

[0053] Optionally, see Figures 5 to 7The chain plate structure 2 further includes two second spacers 272, both of which are sleeved on the support shaft 22, and one of the two second spacers 272 is located between the first plate 211 and the bearing of the rod end joint bearing, and the other of the two second spacers 272 is located between the bearing of the rod end joint bearing and the third plate 213, and the outer diameter of the second spacer 272 is smaller than the outer diameter of the inner ring of the rod end joint bearing. In this way, the second spacers 272 located on both sides of the bearing of the rod end joint bearing limit the axial position of the rod end joint bearing along the support shaft 22, so as to avoid the bearing of the rod end joint bearing from contacting the first plate 211 or the third plate 213, and because the outer diameter of the second spacer 272 is smaller than the outer diameter of the inner ring of the rod end joint bearing, the bearing of the rod end joint bearing and the second spacer 272 have a smaller contact area, thereby reducing the sliding friction resistance between the two, and ensuring that the bearing of the rod end joint bearing can rotate smoothly.

[0054] Optionally, see Figure 7 The roller 23 is the second bearing, and the inner ring of the second bearing is fixedly sleeved on the support shaft 22; the chain plate structure 2 also includes a third spacer 273, which is sleeved on the support shaft 22 and located between the second bearing and the first plate 211. The outer diameter of the third spacer 273 is smaller than the outer diameter of the inner ring of the second bearing. In this way, by setting the roller 23 as the second bearing, the resistance of the roller 23 when rotating is small, and the outer ring of the second bearing can rotate freely around the axis of the support shaft 22 relative to the inner ring of the second bearing, so that the roller 23 and the horizontal plate 101 can roll more smoothly; in addition, the third spacer 273 is set between the second bearing and the first plate 211, which can prevent the outer ring of the second bearing from contacting the first plate 211 or the third spacer 273 when rotating relative to the inner ring of the second bearing. At the same time, the outer diameter of the third spacer 273 is smaller than the outer diameter of the inner ring of the second bearing, which can ensure that there is a small contact area between the second bearing and the third spacer 273, thereby reducing the sliding friction resistance between the two, so that the outer ring of the second bearing can rotate smoothly, and further improve the smoothness of the rolling cooperation between the roller 23 and the horizontal plate 101. Of course, in other embodiments, the roller 23 can also be rotatably sleeved on the support shaft 22 as needed.

[0055] Optionally, the first spacer 271, the second spacer 272 and the third spacer 273 are all made of self-lubricating materials such as nylon, and have a small friction coefficient, which can further reduce the friction resistance between the limiting wheel 24 and the first spacer 271, reduce the friction resistance between the bearing of the rod end joint bearing and the second spacer 272, reduce the friction resistance between the roller 23 and the third spacer 273, and improve the reliability of the rotation of the limiting wheel 24, the rod end joint bearing and the roller 23.

[0056] Optionally, please continue to refer to Figure 7The support shaft 22 includes a first shaft 221 and a second shaft 222 which are coaxial and fixedly connected. The outer diameter of the first shaft 221 is larger than the outer diameter of the second shaft 222, and the outer diameter of the first shaft 221 is smaller than the outer diameter of the inner ring of the second bearing. The outer diameter of the second shaft 222 is matched with the inner diameter of the inner ring of the second bearing. An external thread 223 is provided at one end of the second shaft 222 away from the first shaft 221. The chain plate structure 2 also includes a second nut 282. The second shaft 222 passes through the second bearing, the third spacer 273, the first plate 211, and the third plate 213 in sequence and is threadedly connected to the second nut 282. With such arrangement, when the second nut 282 is tightened, the support shaft 22 can be fixed relative to the base frame 21 and cannot rotate, so that the chain plate structure 2 is more stable; at the same time, it is also convenient for installing and removing the roller 23; in addition, by simultaneously supporting the support shaft 22 by the first plate 211 and the third plate 213, the stability of the support of the support shaft 22 by the base frame 21 can be effectively improved, so that when the roller 23 moves relative to the cross plate 101, the rolling cooperation between the two is more stable.

[0057] Optionally, see Figure 3 , Figure 5 and Figure 6 The base frame 21 also includes a fourth plate 214, which is connected to any one of the first plate 211, the second plate 212, and the third plate 213 at an angle. The fourth plate 214 is located between the first plate 211, the second plate 212, and the third plate 213, and a first hole 219 is provided on the fourth plate 214; the first end of the connecting member 400 is sleeved with the support shaft 22 of the chain plate structure 2 of the first trolley 200, and the second end of the connecting member 400 is plugged into the first hole 219 of the base frame 21 of the chain plate structure 2 of the second trolley 300. The fourth plate 214 can enhance the structural strength of the base frame 21 and make the structure compact. Specifically, in this embodiment, an exemplary scheme of connecting the fourth plate 214 to the first plate 211 at an angle is given; in other embodiments, the fourth plate 214 can also be connected to the second plate 212 or the third plate 213 at an angle as required. In this embodiment, the screw of the rod end joint bearing passes through the first hole 219 and is threadedly connected to the first nut 281; in other embodiments, the first hole 219 can also be set as a threaded hole, and the screw of the rod end joint bearing is threadedly connected to the first hole 219.

[0058] Optionally, please continue to refer to Figure 5 and Figure 6In this embodiment, the fourth plate 214 extends toward the third plate 213; the base frame 21 also includes a fifth plate 215, which is connected to the third plate 213 at an angle and extends toward the first plate 211.

In this way, the structural strength of the base frame 21 can be further improved by setting the fifth plate 215, and the stability of the cooperation between the base frame 21 and the connecting member 400 can be ensured by stacking the fourth plate 214 and the fifth plate 215, so that the first trolley 200 and the second trolley 300 are stably hinged.
