It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the embodiment of the invention, the starting end of the seedling is the starting end, the exit end of the seedling is the end, and the seedling of the throwing machine is in the walking direction.

The seedlings in the tray are finally planted in the farmland. The throwing machine needs to go through the process of picking up, transferring, throwing, etc., wherein the seedlings are taken out from the tray and transported to the throwing device by the transport device 2. 3, the throwing device 3 completes the throwing action, throwing the seedlings into the farmland, and the seedlings thrown into the farmland are to be ensured in rows, arranged in order, providing an environmental basis for the growth of the seedlings, and more convenient for later management. Therefore, the sputum device 2 and the slinging device 3 should be matched in both structure and speed. The embodiment of the invention provides a lateral symmetrical wide-width throwing system, which can arrange the simultaneously thrown seedlings in a straight line. At the same time, many seedlings can be planted efficiently.

In order to make those skilled in the art better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

The array of the first transmission wheels 21 are all located on the same horizontal line perpendicular to the walking direction of the throwing machine, and the arrays of the first transmission wheels 21 have the same diameter. This arrangement ensures that the different feeding belts 22 can simultaneously receive the seedlings, allowing the seedlings to run at the same speed on the conveying device 2 at the same time.

Since each of the belts 22 in the sputum device 2 corresponds to the sling belt 342 in the slinging device 3, that is, the bottom of each of the belts 22 is the throwing At the beginning of the belt 342, the seedlings on the belt 22 reach the ends of the belt 22 and fall to the respective throwing belts 342. In order to ensure that the seedlings on the throwing belt 342 finally form a row, and each plant maintains an equal spacing, it is more convenient for the seedlings on the feeding belt 22 to accurately fall onto the corresponding throwing belt 342. The length of the belt 22 in the example gradually decreases toward the both sides along the intermediate position. In the present embodiment, the intermediate belt 22 is disposed between the first belt 21 and the second belt 23 The length of the belt is 600mm, and the belts 22 on both sides are gradually reduced, and the length of the shortening is 60-70mm.
