[0078] The carrot harvester provided in this embodiment can quantitatively collect and continuously reciprocate the amount of carrots required, which is convenient for quantitative collection of carrots, reduces labor costs, and improves production efficiency. The rotation speed of the active rod 132 is designed by the first driving member 14, and the frequency of the collecting plate 12 can be adjusted, thereby realizing the adjustment of the amount of carrots collected, so as to be suitable for the packing work of manual working platforms of different sizes. The rotation speed of the power output end 1511 is adjusted by the second driving member 151, thereby realizing the change of the reciprocating speed of the first conveying member 157, so that the conveying frequency can be adjusted, and the phenomenon of carrots falling during the box changing process is reduced.

[0079] The carrot harvester provided in this embodiment has the following working principle for quantitative collection:

[0080] The carrots fall onto the collecting plate 12. When the carrots reach a preset weight, the first driving member 14 is started, so that the connecting rod assembly 13 moves along the arc-shaped opening 111, thereby driving the collecting plate 12 to rotate, so that the carrots on the collecting plate 12 fall into the conveying assembly 15, and are conveyed by the conveying assembly 15 to the manual working platform 8 through the gap 112. More specifically, the first driving member 14 is started, and the active rod 132 drives the movable rod 132 to move along the arc-shaped opening, thereby driving the collecting plate 12 to rotate, so that the carrots on the collecting plate 12 fall onto the first conveying member 157, and the second driving member 151 is started, and the power output end 1511 of the second driving member 151 rotates, thereby driving the first transmission member 154 to rotate, and the rotation of the first transmission member 154 drives the second transmission member 155 to rotate, so that the connecting member 158 reciprocates along the sliding member 153, and then the first conveying member 157 reciprocates along the guide member 156, so that the carrots on the first conveying member 157 are transported to the manual working platform 8 through the gap 112.

[0081] The present embodiment provides a carrot harvester, and the working principle of the carrot harvester is as follows:

[0082] The digging and separating component 3 separates the ridges of carrots and digs the carrots separated from the ridges. The angle between the clamping and conveying component 4 and the ground is adjusted by the clamping and conveying component 4. The clamping and conveying component 4 clamps and conveys the dug carrots. During the transportation of carrots, the cleaning component 5 removes the soil and cleans the carrots. When the washed carrots are conveyed to the cutting component 6, the carrot tops are cut so that the carrots fall into the collecting plate 12 of the quantitative collection device 1, and the carrot tops fall to the ground. The carrots that fall into the collecting plate 12 are quantitatively collected according to the working principle of quantitative collection. More specifically, the separating member 31 separates the ridges of the carrots, the digging member 32 digs the carrots with the separated ridges, the angle between the second conveying member 41 and the ground is adjusted by the angle adjusting member 42, and the second conveying member 41 clamps and conveys the dug carrots under the drive of the third driving member. During the carrot conveying process, under the drive of the fourth driving member, the rotating member 51 rotates and drives the cleaning member 52 to rotate, thereby removing the soil and cleaning the carrots. When the washed carrots are conveyed to the cutting assembly 6, the cutting member 61 cuts the carrot tops so that the carrots fall through the first guide member 62 into the collecting plate 12 of the quantitative collecting device 1, and the carrot tops are continued to be conveyed so that the carrot tops fall through the second guide member 63 to the ground, and the carrots that fall into the collecting plate 12 are quantitatively collected according to the working principle of quantitative collection.

[0083] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
