Specifically, referring to fig. 6 to 10, the main transmission mechanism 100 includes:

support frames 110 provided on both sides;

the chain transportation assembly comprises a first driving motor (not shown), at least two chain wheels 121 which are connected with the first driving motor in a driving way and are arranged on each supporting frame 110, and a chain 122 which is arranged on the periphery of the chain wheels 121, wherein the first driving motor drives the chain wheels 121 to rotate, and the chain wheels 121 drive the chain 122 to do rotary motion;

the tray assembly 200 is disposed on the chain 122 and moves with the movement of the chain 122.

The transport mechanism shown in fig. 6 and 10 does not include a portion of the chain 122 wound around the sprocket 121 for clarity of illustration. In practical situations, the chain 122 is wound around the sprocket 121, the sprocket 121 drives the chain 122 to perform a rotation motion, and the chain 122 drives the pan assembly 200 to perform a rotation motion from an upper position to a lower position and then from the lower position to the upper position.

The chain 122 is wound around the plurality of sprockets 121 once, and the plurality of sprockets 121 are rotated in the same direction by the driving of the first driving motor, so that the chain 122 wound around the plurality of sprockets is rotated in the same direction. Alternatively, the support frame 110 on one side is correspondingly provided with a sprocket 121, the support frame 110 on the other side is correspondingly provided with another sprocket 121, and the chain 122 is wound around the two sprockets 121, so that when the two sprockets 121 rotate in the same direction, the chain 122 rotates along with the rotation direction.

The tray assembly 200 is fixedly disposed on the chain 122, and when the chain 122 rotates, the tray assembly 200 fixed on the chain 122 rotates along with the chain, so that the goods placed on the tray assembly 200 moves along with the movement of the tray assembly 200.

When the tray assembly 200 is in the up position, goods are placed on the tray assembly 200. The tray assembly 200 drives the goods to move, if the goods reach the corresponding sorting position, the tray assembly 200 rotates, and the goods slide down from the tray assembly 200 and slide down to the first object throwing assembly 400 corresponding to the lower part. After the goods slide down, the tray assembly 200 continues to perform a turning motion along with the chain 122, and when the tray assembly 200 moves to the upper position again, the next goods are placed on the tray assembly 200, and the goods sorting process is continued.

The main transmission mechanism 100 provided by the utility model does not need to use a tray, namely, does not need to recycle the tray, has a simple structure and low manufacturing cost, and is suitable for long-distance transmission.

Further, referring to fig. 6, the main transmission mechanism 100 further includes:

and a fluent strip 130 disposed between the upper and lower tray assemblies 200 and 200 for reducing friction force applied to the tray assembly 200 during the rotation.

On the endless chain 122, a tray assembly 200 is provided. The tray assembly 200 moves from an upper position to a lower position as the chain 122 rotates, with the remaining tray assemblies 200 remaining in the upper position, ensuring that the goods sorting process is not interrupted.

The fluent strip 130 is disposed at a location between the upper tray assembly 200 and the lower tray assembly 200, i.e., at an intermediate portion of the upper and lower positions. In detail, the chain 122 is in a loop shape and rotates, and the direction of the fluent strip 130 is on the same horizontal line as the horizontal middle direction of the loop shape.

During the rotation of the tray assembly 200, both the tray assembly 200 located above and the tray assembly 200 located below can reduce the friction force under the action of the fluent strip 130, thereby ensuring smooth movement.

It should be noted that, if the chain 122 is not fully covered with the tray assembly 200, that is, when the tray assembly 200 moves from the upper position to the lower position, the tray assembly 200 is not present in the upper position, and this situation can be understood as a simple modification of the present embodiment, which is also within the protection scope of the present utility model.

Optionally, the fluency strip 130 is provided with two strips, which are respectively arranged at two sides of a position between the upper tray assembly 200 and the lower tray assembly 200 which do rotary motion. Providing a plurality of fluency strips 130 may further reduce the friction experienced by the tray assembly 200 during the rotation.

In this embodiment, when the chain 122 rotates, the fixing plate 210 is driven to rotate, and the rotation driving assembly 220 and the turning plate structure 230 rotate along with the fixing plate 210. When the tray structure 230 reaches the sorting position, the rotation driving assembly 220 drives the tray structure 230 to perform rotation movement, and the goods on the tray structure 230 slide down to the first object throwing assembly 400.

More specifically, referring to fig. 7 to 9, the rotation driving assembly 220 includes:

a second driving motor 221 fixedly provided on the fixing plate 210;

a rotating structure which is in driving connection with the second driving motor 221 and is connected with one side of the turning plate structure 230;

a follower structure disposed on the other side of the pan structure 230 and below the pan structure 230.

In this embodiment, the second driving motor 221 drives the rotating structure to rotate, the rotating structure drives the tray structure 230 to rotate, but the following structure at the other side does not move, and only rotates along with the tray structure 230, so as to ensure that the tray structure 230 normally rotates, and thus the goods can slide from the tray structure 230 to the first object feeding assembly 400. By adopting a one-side main driving mode, the turning plate structure 230 can be ensured to smoothly perform rotational movement, and the cost can be saved.

Referring to fig. 8, the rotating structure includes a driving wheel 222 drivingly connected to the second driving motor 221, a driven wheel 223 disposed adjacent to the driving wheel 222, a winding belt 224 surrounding the driving wheel 222 and the driven wheel 223, and a first fixing member 225 respectively connected to the driven wheel 223 and the tray structure 230 and fixedly disposed on the fixing plate 210.

In this embodiment, the second driving motor 221 drives the driving wheel 222 to rotate, the driving wheel 222 drives the winding belt 224 to rotate, and friction exists between the winding belt 224 and the driven wheel 223, so that the winding belt 224 drives the driven wheel 223 to rotate. When the driven wheel 223 rotates, the turning plate structure 230 is driven to rotate.

The first fixing member 225 can provide a supporting force for the driven wheel 223, so as to ensure that the acting force of the driven wheel 223 on the tray structure 230 acts on the tray structure 230 smoothly.

Preferably, the diameter of the driving wheel 222 is smaller than the diameter of the driven wheel 223.

Referring to fig. 9, the follower structure includes a second fixing member 226 fixedly disposed on the fixing plate 210 and a follower 227 rotatably connected to the second fixing member 226, and the follower 227 is further connected to the pan structure 230 and is rotatable with the rotation of the pan structure 230.

The follower 227 is fixedly connected to the pan structure 230, and the second fixing member 226 is fixed on the fixing plate 210, where the second fixing member 226 provides a supporting force to the follower 227. During the rotation of the pan structure 230, the second fixing member 226 is fixed, and the follower 227 rotates on the second fixing member 226 along with the rotation of the pan structure 230.

Specifically, referring to fig. 10, the supporting frame 110 includes:

two support columns 111;

the limiting pieces 112 are respectively arranged on the supporting columns 111;

a roller 113 disposed on the stopper 112 and passing through the sprocket 121.

It is possible that the first driving motor drives the connection roller 113, the first driving motor drives the roller 113 to rotate, and the roller 113 drives the sprocket 121 to rotate.

The support column 111 provides a supporting force for the stopper 112.

The limiting member 112 provides a limiting effect to the roller 113, and avoids shifting the position when the roller 113 rotates. As shown in fig. 5, the stopper 112 may be provided as an annular bar fixedly provided on the support column 111, and the roller 113 is provided through the annular bar.

Referring to fig. 10, the supporting frame 110 further includes:

and a sleeve 114 arranged outside the limiting piece 112 and sleeved on the roller 113.

Because the roller 113 can generate fine deviation in the rotation process, the sleeve 114 is arranged at the outer sides of the limiting parts 112 at two sides, and the sleeve 114 is slightly larger than the limiting parts 112, so that the roller 113 can be prevented from penetrating out of the limiting parts 112 in the rotation process, and the roller 114 is further ensured to normally drive the chain wheel 121 to rotate.

It should be noted that, the structural implementation manner of the secondary transmission mechanism 300 and the auxiliary transmission mechanism may be the same as that of the primary transmission mechanism 100, that is, the secondary transmission mechanism 300 is also provided with structures such as a support frame 110 and a chain transportation assembly, and the auxiliary transmission mechanism is also provided with structures such as a support frame 110 and a chain transportation assembly.
