Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, a whole row of seedling ejector device based on a snail cam mechanism includes a motor 1, a right-angle plate 2, a snail cam 15, a bearing support assembly and a seedling ejector rod assembly, and the motor 1 inputs power to the camshaft through a coupling 3 16. The bearing support assembly supports the rotation of the camshaft 16, and the camshaft 16 drives the snail cam 15 to enter the push section to make the ejector rod assembly eject the seedlings. At the same time, the return spring 6 installed on the ejector rod frame 8 is compressed, and the ejection ends. After the snail cam 15 enters the return section, the back-moving spring 6 recovers the original length, and the top seedling bar frame 8 returns quickly along the chute 5 under the action of the back-moving spring 6, driving the top seedling bar 7 to withdraw...

Abstract

The invention discloses a whole-row seedling ejecting device based on a worm cam mechanism. At present, the existing tray seedling taking device takes out seedlings mainly by pulling out the seedlingsby using seedling needles, so that seedling roots, seedling stems and a matrix structure are easily damaged and the seedlings need a certain growth recovery period. The whole-row seedling ejecting device comprises a motor, a right-angled plate, a worm cam, a bearing support assembly and a seedling ejecting rod assembly, wherein the motor inputs power into a cam shaft through a shaft coupler; thebearing support assembly supports the cam shaft to rotate; the cam shaft drives the worm cam to enter a pushing section so as to enable the seedling ejecting rod assembly to eject the seedlings, and return springs mounted on a seedling ejecting rod frame are compressed; after completion of seedling ejection, the worm cam enters a returning section, the return springs are restored to the original lengths, and the seedling ejecting rod frame quickly returns along sliding slots under the action of the return springs so as to drive seedling ejecting rods to exit from small holes in the bottom of atray. In a whole-row seedling ejecting way, the whole-row seedling ejecting device greatly improves the transplanting efficiency; the worm cam mechanism is simple in structure and reliable in working; the seedling ejecting rod assembly can achieve intermittent seedling ejection.

Description

technical field [0001] The invention belongs to the field of agricultural mechanization research and relates to a device for topping seedlings in a row based on a snail cam mechanism. Background technique [0002] Plug seedling transplanting technology is a measure to increase production in modern agriculture. Seedling cultivation and transplanting can prevent crops from being affected by harsh climates such as cold in late spring and low temperature in early spring, ensure that the seedlings are complete, uniform, uniform, and strong, shorten the field production period, and increase the survival rate of seedlings , It is of great significance to increase the yield per unit area of ​​crops and develop high-yield and high-efficiency agriculture. [0003] At present, the existing plug seedling harvesting device is mainly a pull-out type seedling harvesting method in which the seedling needle is inserted into the plug matrix or the stem of the plug seedling is clamped, which i...
