The conveying and separating device comprises a conveying assembly 6, a tray seedling introducer 5, and a tray guide 8 for separating the tray 13 and the seedling, the tray guide 8 being disposed near the end of the conveying assembly 6, The tray seedling introducer 5 is disposed at the beginning end of the conveying assembly 6, the shape of the tray seedling introducer 5 is matched with the shape of the tray 13, and the tray seedling introducer 5 is arranged along the seedling running direction. The sides are provided with ribs. The transport assembly 6 in the embodiment of the present invention employs a chain assembly including a chain 4, a first sprocket and a second sprocket 7.

In the embodiment of the present invention, the distance between the two sides of the tray seedling introducer 5 is the distance between the two sides of the tray 13 along the seedling running direction. In this embodiment, the distance between the two sides of the tray seedling introducer 5 is equal to the distance between the two sides of the tray 13, and the tray 13 is placed on the tray seedling introducer 5, and the tray seedling is introduced. The rib on the device 5 just snaps the tray 13, and the tray 13 runs in a fixed direction on the tray seedling introducer 5, without arbitrarily oscillating affecting subsequent processes.

In the embodiment of the present invention, the tray seedling introducer 5 is disposed at a starting end of the conveying assembly 6 in a slope form, and the tray seedling introducer 5 is movably connected with the frame 12 to be connected around the connecting shaft. The axis is flipped. After the tray 13 and the seedlings are placed on the tray seedling introducer 5, the tray 13 is slid down along the tray seedling introducer 5 by gravity, and is slid down onto the conveying assembly 6, by the chain. 4 drives the disk 13 to run forward.

In the direction in which the seedlings are running, the two sides of the tray seedling introducer 5 are on the same line as the first pulley 2 and the brancher 3 at both ends. It can also be understood that the tray seedling introducer 5 has the same width as the branching device and the picking device, and is arranged to further define the movable range of the tray 13 and the seedling, and the tray 13 and the seedling are set according to the setting. The route runs, and finally the order of the seedlings thrown by the throwing machine is guaranteed.

In the present invention, as can be seen from Fig. 2, the used tray 13 is provided with a uniform arrangement, a row of rows of depressions for placing seedlings, and a certain gap between the rows of depressions, the existing tray 13 , the gap usually forms a groove, in the embodiment of the invention, the conveying assembly 6 skillfully utilizes the grooves between the rows, and the adjacent chain 4 in the conveying assembly 6 can be according to the concave The groove is adjusted so that the distance between adjacent chains 4 is an integral multiple of the distance between adjacent grooves, so that the tray 13 is slid onto the conveying member by the tray seedling introducer 5 After 6th, the groove on the tray 13 is just aligned with the chain 4. At this time, the chain 4 restricts the movement of the groove, so that the tray 13 cannot move or swing left and right, and can only run forward along the running direction of the chain 4.

If the length of the chain 4 in the transport assembly 6 is set too long, the chain The strip 4 may sag slightly due to its own gravity, and may not sufficiently contact the groove on the tray 13, affecting the accuracy of transportation, so the number of the conveying assemblies 6 may be appropriately set according to the transportation distance.

The composition and arrangement of the above-mentioned conveying assembly 6 are only one of the implementation manners, but should not be taken as a limitation of the scope of the present invention. Those skilled in the art may select other components and setting forms according to actual conditions, which should all be It falls within the scope of protection of the present invention.

Due to the characteristics of the seedlings, the seedlings in the tray 13 are only fixed to the roots of the seedlings 13, but the leaves of the adjacent seedlings are easily crossed and interact with each other if the leaves of the seedlings are crossed together for picking. Seedlings in different rows may not be able to enter the corresponding take-up belt, causing all subsequent procedures to be wrong, resulting in the disorderly distribution of seedlings thrown into the farmland, affecting subsequent management and seedling growth. Therefore, the seedlings need to be branched before entering the picking device.

As shown in FIG. 3 and FIG. 4, the branching device includes an array of the splitter 3 adjacent to the first pulley 2, and the brancher 3 has a front thin and a thick front, and a front lower portion that protrudes forward. In the running direction of the seedling, the branching device 3 and the first pulley 2 are on the same straight line, and the distance between the adjacent branching devices 3 and the distance between the adjacent first pulleys 2 Equally, the rear curved edge of the brancher 3 matches the shape of the first pulley 2.

The branching device 3 is disposed between the picking device and the pumping device. When the tray 13 and the seedling are operated to the branching device 3, the lower end of the branching device 3 is thinner and longer than the upper end. It facilitates the smooth distribution of the crossed seedlings into one of the corresponding take-up belts.

In the picking device, after the seedling is gripped by the take-up belt 1, it needs to be separated from the tray 13, and then continue to run forward, so that the tray 13 needs to be directed in a different direction from the seedling operation.

As shown in FIGS. 5 and 6, the disk guide 8 in the embodiment of the present invention has an arc-like structure that matches the shape of the second sprocket 7 at the end of the conveying assembly 6. A certain gap is left between the disk guide 8 and the second sprocket 7, and the gap is preferably passed through the disk 13 smoothly. The direction of the arc-shaped structure is directed downward, and the disc 13 is detached from the seedling under the obstruction of the disc guide 8, and the seedling is run forward under the leadership of the pick-up belt 1, and the tray 13 is in the crucible Under the action of the disc guide 8, it starts to change the original running direction and runs downward.

In the throwing machine, a tray collecting device is further disposed under the tray guide 8 for collecting the fallen tray 13 to facilitate recycling of the tray 13, saving resources and avoiding the tray. 13 scattered to the farmland, saving time in the collection of the tray 13 later.

Corresponding to an embodiment of the sputum seedling conveying branching and picking system provided by the present invention, the present invention further elaborates on the working principle of the sputum seedling conveying branching system.
