The third bracket 44 and the pneumatic spring 45. The first bracket 42 has a first connecting end and a second connecting end, the second bracket 43 has a third connecting end and a fourth connecting end, the first connecting end and the third connecting end are arranged opposite to each other, and the first connecting end is connected to the first clamping group 21, the third connecting end is connected to the second clamping group 22, the second connecting end and the fourth connecting end are connected to the first fulcrum, a pneumatic spring 45 is hinged between the first bracket 42 and the second bracket 43, the third bracket 44 is hinged to the first fulcrum, the other end of the third bracket 44 extends forward and is connected to the loosening shovel 41, and the other end of the pneumatic spring 45 is hinged to the third bracket 44.

[0077] In this embodiment, the frame 1 includes a first support beam 11 and a second support beam 12, wherein the first support beam 11 is relatively distributed on both sides of the entire plucking mechanism, and the number of the second support beams 12 is multiple, and the multiple second support beams 12 are erected between the two first support beams 11. As an optional embodiment, the first support beam 11 has a certain angle with the horizontal plane, that is, Figure 1 As shown, the first support beam 11 is tilted from front to back, which is consistent with the height direction of the carrots gradually rising during the pulling process.

[0078] In this embodiment, at least one clamping assembly 2 is further provided between the two first supporting beams 11. Optionally, the number of the clamping assemblies 2 can be set according to actual conditions, such as Figure 1 An example is shown in which three clamping assemblies 2 are spaced apart between two first support beams 11.

[0079] Furthermore, each clamping assembly 2 includes a first clamping group 21 and a second clamping group 22 that are relatively arranged. The extension direction of the first clamping group 21 and the second clamping group 22 is consistent with the first support beam 11. When the first support beam 11 is tilted, the first clamping group 21 and the second clamping group 22 are also tilted.

This structure uses the first clamping group 21 and the second clamping group 22 as a fixing method for the loosening shovel 41, reduces the complexity of the frame 1, and takes into account the position setting of the loosening shovel 41 and the operational connection between the clamping assembly 2. In this embodiment, a pneumatic spring 45 is further provided on the third bracket 44. The pneumatic spring 45 can adjust the elastic force of the pneumatic spring 45 according to the air pressure.

Two first rotating plates 217 are sleeved on each first adjusting shaft 216, and the first driven roller 213 is arranged between the two first rotating plates 217; the first torsion spring 218 is sleeved on the first adjusting shaft 216, and the number of the first torsion spring 218 corresponds one-to-one to the number of the first adjusting shafts 216, one end of the first torsion spring 218 abuts against the first fixed plate 212, and the other end of the first torsion spring 218 abuts against the first rotating plate 217.

[0090] In this embodiment, the first clamping group 21 further includes a first adjustment shaft 216, a first rotating plate 217 and a first torsion spring 218. The specific adjustment method can be referred to Figure 4 and Figure 6For ease of understanding, a first adjustment shaft 216 is used as an example for explanation, with the direction away from the clamping gap as the outside and the direction close to the clamping gap as the inside: the first adjustment shaft 216 is arranged between the two first fixed plates 212, the number of the first rotating plates 217 is two, which are relatively arranged on the same first adjustment shaft 216, and the first driven roller 213 is arranged between the two first rotating plates 217, so that the first driven roller 213 can rotate relative to the first adjustment shaft 216 under the drive of the first rotating plate 217. The first torsion spring 218 is sleeved on the first adjustment shaft 216 and arranged between the two first rotating plates 217. One end of the first torsion spring 218 is in contact with the first fixed plate 212, and the other end of the first torsion spring 218 is in contact with one of the first rotating plates 217. When the first driven roller 213 is subjected to force to swing outward relative to the first adjusting shaft 216, the end of the first torsion spring 218 in contact with the first rotating plate 217 is compressed by force, and the other end of the first torsion spring 218 is in contact with the first fixed plate 212 and is in a state where it cannot be deformed. Under the action of elastic potential energy, the first rotating plate 217 will be driven by the elastic force of the first torsion spring 218 to swing inward by the first driven roller 213, thereby achieving the function of ensuring that the carrot tops in the clamping gap are always in contact with the inner surface of the first conveyor belt 211, maintaining the friction between the carrot tops and the first conveyor belt 211, so that the carrot tops can be effectively clamped.

[0092] In some embodiments, the second clamping group 22 also includes a second adjusting shaft, a second rotating plate and a second torsion spring. The second adjusting shaft is arranged on the second fixed plate, and the number of the second adjusting shafts corresponds one-to-one to the number of the second driven rollers; one end of the second rotating plate is sleeved on the periphery of the second adjusting shaft, and the other end of the second rotating plate extends outward to connect with the second driven roller. Two second rotating plates are sleeved on each second adjusting shaft, and the second driven roller is arranged between the two second rotating plates; the second torsion spring is sleeved on the second adjusting shaft, and the number of the second torsion springs corresponds one-to-one to the number of the second adjusting shafts, one end of the second torsion spring abuts against the second fixed plate, and the other end of the second torsion spring abuts against the second rotating plate.

The first slider 24 is connected to the first fixed plate 212, and the second slider 25 is connected to the second fixed plate. By adjusting the first slider 24 and the second slider 25, the distance between the first fixed plate 212 and the second fixed plate can be adjusted to achieve the adjustment of the distance between the first conveyor belt 211 and the second conveyor belt 221, that is, the size of the clamping gap is adjusted to adapt to carrot tops of different widths. A first fastener 26 is provided on the first slider 24, and a second fastener 27 is provided on the second slider 25.
