It is an efficient automatic conveying equipment used to change the direction of material conveying, which is convenient for sending materials from the fork to or from the main conveying line. Because of its large load capacity, simple structure, stability and reliability, it is often used for logistics roller transportation. The equipment adopts PLC programmable control, so that materials can enter and exit the main and auxiliary conveying lines conveniently and smoothly without collision, extrusion, etc.

If used in a double-layer logistics roller system, the center distance between the double-layer rollers will become narrower during the logistics production and transportation process, affecting the normal passage of materials. In terms of inspection and maintenance, since the motor and cylinder are designed to be built-in, once the motor or cylinder is damaged, it will be necessary to temporarily stop production or manually replace the transportation in this range, disassemble the entire transplanter, take out the damaged motor or cylinder, and repair and replace it until the normal transportation task can be guaranteed, resulting in a huge waste of manpower and resources, and directly affecting production efficiency.

When in use, the utility model is connected to the fork of the main conveyor line through the base plate 1. When the target material is in place, the lifting mechanism 5 lifts the transfer frame 2 corresponding to the main conveyor line, and sends the target material into or out of the main conveyor line through the conveying mechanism 3.

[0028] In order to facilitate the installation and maintenance of the lifting mechanism 5 , the lifting mechanism 5 is arranged outside the transfer frame 2 to facilitate the daily maintenance of the lifting mechanism 5 .

[0029] As a preferred embodiment, the transfer frame 2 is formed by a top plate 21, a bottom plate 22, a rear frame plate 23 and two side frame plates 24. The conveying mechanism 3 includes a plurality of conveying chains 31 arranged on the top plate 21 for material conveying. The conveying chains 31 are connected to a power device 32 in a transmission manner to obtain the traveling power of the conveying chains 31.

[0030] Preferably, the conveying chain 31 is connected to the top plate 21 through a chain bracket 33. Specifically, both ends of the chain bracket 33 in the length direction are rotatably connected to bracket sprockets 331, and the conveying chain 31 is meshed and supported on the bracket sprockets 331. A driving shaft 34 is rotatably connected in the transfer frame 2, and a driving sprocket 35 is provided on the driving shaft 34 corresponding to the conveying chain 31. The conveying chain 31 is meshed and connected to the driving sprocket 35, and the driving shaft 34 is connected to the power device 32 in a transmission manner to drive the conveying chain 31 to move forward. Preferably, a driving sprocket is provided on the driving shaft 34, and the output end of the power device 32 is connected to the driving sprocket in a transmission manner to obtain the rotational power of the driving shaft 34.

[0031] As a preferred embodiment, the power device 32 is arranged outside the transfer frame 2 to further reduce the volume configuration of the transfer frame 2, optimize the height of the whole machine structure, and thus increase the scope of application in the logistics field. At the same time, the external power device 32 further facilitates equipment maintenance.

By adjusting the rotation angle of the angle double-shaft seat 39 with the driving shaft 34 as the axis, the driven shaft 36 can be moved closer to or farther from the conveying chain 31, thereby achieving the purpose of tension adjustment of the conveying chain 31. This embodiment avoids the interference problem when adjusting the conveying chain 31, making maintenance more convenient and reliable.

In this embodiment, the guide structure will automatically calibrate during the lifting process to maintain the stable state of the transplanter body, thereby improving the operation stability and accuracy. The guide structure is preferably a sealed structure to extend its maintenance cycle and service life.

[0039] Preferably, a plurality of conveyor chains 31 are staggered in the width direction, so that different conveyor chains 31 form a concave-convex shape of one in and one out at the end of the transfer frame 2. This facilitates the insertion and transition of the conveyor chains 31 between the conveying mechanism 3 and the main conveying line and the fork, improves the stability during the receiving / feeding process, and realizes the function of forward and reverse bidirectional feeding and outflow of materials.
