[0091] The tassel cutting component 5 is arranged on the frame 1, and the tassel cutting component 5 includes a first cutter 51. The first cutter 51 is arranged below the first conveyor belt 211 and the second conveyor belt 221, and is arranged below the output end of the clamping gap, and the first cutter 51 is used to cut the carrot tassels; the tassel removing component 6 is arranged on the frame 1, and the tassel removing component 6 includes a tassel receiving tube 61. The tassel receiving tube 61 is arranged at the output end of the clamping gap, and both ends of the tassel receiving tube 61 are provided with end openings, and the tassel receiving tube 61 is used to receive the cut carrot tassels so that the cut carrot tassels can be released from the end openings at both ends; the conveying component 7 is arranged on the frame 1, and the conveying component 7 is arranged below the tassel cutting component 5, and the conveying component 7 is used to convey the cut carrots; the collecting component 8 is arranged on the frame 1, and the collecting component 8 includes a collecting basket 81, which is arranged at the output end of the clamping component 2, and the collecting basket 81 is used to collect carrots.

[0092] In this embodiment, the frame 1 includes a first support beam 11 and a second support beam 12, wherein the first support beams 11 are relatively distributed on both sides of the entire carrot machine, and the number of the second support beams 12 is multiple, and the multiple second support beams 12 are erected between 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 carrot gradually rising during the pulling process. In this embodiment, at least one clamping assembly 2 is further provided between the two first support beams 11. Optionally, the number of 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. This method can simultaneously harvest three rows of carrots, thereby improving the harvesting efficiency.

[0093] The tassel-supporting component 3 is used to gather the carrot tassels so as to place them in the clamping gap. Specifically, the tassel-supporting component 3 includes a first tassel-supporting cone 31 and a second tassel-supporting cone 32. The first tassel-supporting cone 31 and the second tassel-supporting cone 32 are arranged opposite to each other. Optionally, the first tassel-supporting cone 31 can be arranged at the end of the first clamping group 21 close to the input port of the clamping gap, and the second tassel-supporting cone 32 can be arranged at the end of the second clamping group 22 close to the input port of the clamping gap. It should be noted that the structure of the first tassel-supporting cone 31 and the second tassel-supporting cone 32 is a cone structure, and the cone end of the cone structure is arranged forward to facilitate insertion into the connection between the fallen carrot tassels and the carrots, and to gather the carrot tassels to the middle from both sides. With the characteristics of the cone structure, the gathered carrot tassels are synchronously introduced into the clamping gap to guide the carrot tassels, that is, the tassel-supporting component 3 can play the role of gathering and guiding the carrot tassels. The soil-loosening component 4 is used to transport the soil in the carrot growing area, so that the carrots can be easily taken out of the soil during the subsequent removal operation.

[0094] The clamping assembly 2 includes a first clamping group 21 and a second clamping group 22 which are arranged opposite to each other. 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 inclined, the first clamping group 21 and the second clamping group 22 are also inclined. In this embodiment, a clamping gap is formed by the relative arrangement of the first clamping group 21 and the second clamping group 22. Specifically, the first clamping group 21 includes a first conveyor belt 211, and the second clamping group 22 includes a second conveyor belt 221. The conveying surface of the first conveyor belt 211 and the conveying surface of the second conveyor belt 221 are arranged opposite to each other, and a clamping gap is formed between the two conveying surfaces. The carrot tops are placed in the clamping gap and are gradually lifted upward by the first conveyor belt 211 and the second conveyor belt 221 under the drive of friction, so as to achieve clamping and pull upward at the same time, so as to drive the carrots connected to the carrot tops out of the soil, and complete the carrot pulling operation. The first preset gradient and the second preset gradient can be the same. The first preset gradient can be understood as the parameter value of the lifting trend of the first conveyor belt 211, and the second preset gradient can be understood as the parameter value of the lifting trend of the second conveyor belt 221. When the first preset gradient and the second preset gradient are the same, the first conveyor belt 211 and the second conveyor belt 221 are set in parallel.

[0095] The cutting component 5 is a component for cutting off the carrot tassels. The cutting component 5 specifically includes a first cutter 51. The first cutter 51 is arranged below the first conveyor belt 211 and the second conveyor belt 221, and is specifically arranged below the output end of the clamping gap. It should be noted that the output end and the input end are distinguished according to the direction of clamping and pulling out the carrots. The first cutter 51 can cut off the carrot tassels when the carrot tassels and the carrots are transported to a high place, and the carrots fall to the conveying component 7 below under the action of their own weight to achieve the harvesting of the carrots.

[0096] The tassel removal component 6 is arranged at the output end of the clamping gap, and the tassel removal component 6 includes a tassel tube 61, which is a tube structure with end openings at both ends and a hollow middle part, and an opening is arranged on the side of the tassel tube 61, that is, the cross section of the tassel tube 61 is U-shaped, and the opening on the side can be used to accommodate the clamping component 2, so that the output end of the clamping gap enters the tassel tube 61 from the U-shaped opening to transport the cut carrot tassels into the tassel tube 61. As the number of carrot tassels increases, the excess carrot tassels will be squeezed into the end openings at both ends and fall off, so as to be re-covered on the soil and return to the soil as fertilizer.

[0097] In this embodiment, the conveying assembly 7 is arranged on the frame 1, and the conveying assembly 7 is arranged below the output end of the clamping gap, specifically below the tassel cutting assembly 5. When the carrots fall, they will be received by the conveying assembly 7, and then the collected carrots will be transported to the collecting assembly 8. In this embodiment, the collecting assembly 8 includes a collecting basket 81. Optionally, the collecting basket 81 can be a two-wheeled basket with a push rod. The collecting basket 81 can be fixed to the frame 1 by a snap-fitting form to receive the carrots. When the carrots are full, the collecting basket 81 can be directly removed from the frame 1 by holding the push rod to replace the next collecting basket 81.

[0098] This embodiment realizes the harvesting, cutting, de-tasseling, transportation and collection of carrots through a series of components and operations, improves the harvesting efficiency, and reduces the adhesion of carrots to the soil, thereby improving the quality and effect of harvesting.

[0100] Furthermore, the tassel removal component 6 shown in this embodiment also includes a fan 62 and a blow pipe 63. The fan 62 is arranged on the frame 1. One end of the blow pipe 63 is connected to the fan 62, and the other end of the blow pipe 63 is arranged toward the tassel connection tube 61. Specifically, the blow pipe 63 is arranged toward an end opening of the tassel connection tube 61. The fan 62 can be a centrifugal fan 62 to achieve the high-speed blowing requirement. The first direction here can be understood as the blowing direction of the blow pipe 63. Preferably, the first direction is consistent with the axial direction of the tassel connection tube 61. The carrot tassels in the tassel connection tube 61 can be removed in time by blowing, so as to avoid the problem of too many carrot tassels falling onto the conveying component 7.

[0101] In some embodiments, the conveying assembly 7 includes a first roller group 71 and a second roller group 72. The first roller group 71 is arranged below the cutting assembly 5, and the first roller group 71 includes a plurality of first conveying rollers 711, and the plurality of first conveying rollers 711 are spaced apart along the first conveying direction; the second roller group 72 is connected to the end of the first roller group 71, and the second roller group 72 includes a plurality of second conveying rollers 721, and the plurality of second conveying rollers 721 are spaced apart along the second conveying direction, and the first conveying direction is arranged at an angle to the second conveying direction, and a collecting basket 81 is provided at the output end of the second roller group 72.

[0102] See also Figure 4 and Figure 5The conveying assembly 7 includes a first roller group 71 and a second roller group 72, wherein the first conveying rollers 711 of the first roller group 71 are spaced apart along the first conveying direction, and the second conveying rollers 721 of the second roller group 72 are spaced apart along the second conveying direction, and the first conveying direction and the second conveying direction are arranged at an angle, preferably, the first conveying direction and the second conveying direction are arranged perpendicularly, and the structures of the first conveying roller 711 and the second conveying roller 721 can be the same. Specifically, the first conveying roller 711 is arranged below the tassel cutting assembly 5, and the rotation of the first conveying roller 711 can move the carrots along the first conveying direction; under the action of inertia, when the carrots move to the connection between the first conveying roller 711 and the second conveying roller 721, the carrots will move to the top of the second conveying roller 721, and the second conveying roller 721 will then transport the carrots to the collection basket 81, completing the transportation of the carrots.

[0103] In some embodiments, the carrot cutting assembly 5 also includes a roller 52, a cam 53, a first knife holder 54 and a first driving unit 55.
