The eccentric shaft can be sleeved with a rotating sleeve, so that the friction force between the eccentric shaft and the front hoop rope 31 is reduced.

Referring to fig. 5, as an embodiment of the adjustable seedling binding apparatus provided in the present application, the rear tightening mechanism 4 includes a rear hoop rope 41, a first rear push rod 42, and a second rear push rod 43; the first rear push rod 42 and the second rear push rod 43 are respectively arranged at two sides of the rear part of the binding space 11 and can oppositely extend; the rear hoop rope 41 spans the rear end of the binding space 11 and forms a rear bracket 411 for accommodating the upper end of the trunk of the nursery stock 7; the two ends of the rear hoop rope 41 are fixed after bypassing the ends of the first rear push rod 42 and the second rear push rod 43 respectively, so that after the first rear push rod 42 and the second rear push rod 43 are elongated in opposite directions, the two ends of the rear bracket 411 can be pushed to be closed, and the upper ends of the trunk parts of the seedlings 7 can be tightened.

The two ends of the rear hoop rope 41 are mutually fixed to form a ring shape, the ring-shaped rear hoop rope 41 is spread by a rear wheel group, and the opening of the rear bracket 411 is outwards.

The movable frame 1 is provided with a turnover mechanism 12 and a rear turnover mechanism 13, the turnover mechanism 12 drives the front hoop rope 31 to circumferentially and circularly move, and the rear turnover mechanism 13 drives the rear hoop rope 41 to circumferentially and circularly move so as to drive the trunk parts of the seedlings 7 in the front supporting bend 311 and the rear supporting bend 411 to rotate.

The control unit 6 is respectively connected with the turnover mechanism 12 and the rear turnover mechanism 13 in a control manner so as to control the rotating speeds of the turnover mechanism 12 and the rear turnover mechanism 13.

The control unit 6 is adapted to calculate the length of the front bracket 311 based on the extension lengths of the first front push rod 32 and the second front push rod 33, calculate the length of the rear bracket 411 based on the extension lengths of the first rear push rod 42 and the second rear push rod 43, and control the rotation speed ratio of the turnover mechanism 12 and the rear turnover mechanism 13 based on the ratio of the length of the front bracket 311 to the length of the rear bracket 411.

In actual use, since the root of the seedling 7 has a large volume, the entire seedling 7 is not approximately cylindrical, and thus, when the seedling 7 is stacked in the binding space 11, the entire seedling 7 is not cylindrical, but approximately conical. If the turnover mechanism 12 and the rear turnover mechanism 13 rotate at the same rotation speed, the upper end and the lower end of the seedling 7 are twisted.

In this embodiment, the control unit 6 controls the rotation speed ratio of the turnover mechanism 12 to the rear turnover mechanism 13 according to the ratio of the length of the front bracket 311 to the length of the rear bracket 411, so that the upper and lower ends of the nursery stock 7 in the binding space 11 can synchronously or approximately synchronously rotate, and torsion is avoided.

In this embodiment, when the front tightening mechanism 3 tightens the seedling 7 through the front hoop rope 31, the tightening force of the front bracket bend 311 on the seedling 7 is positively correlated with the tension of the front hoop rope 31, and the tension of the front hoop rope 31 is positively correlated with the pressure of the front hoop rope 31 on the guide wheel, so that the control unit 6 can determine the tightening degree of the front bracket bend 311 on the seedling 7 by acquiring the pressure data of the front pressure sensor 34, and further can control the extending lengths of the first front push rod 32 and the second front push rod 33, so as to avoid the tightening and the overtightening of the front bracket bend 311 on the seedling 7. Similarly, the control unit 6 may also determine the tightening degree of the back supporting bend 411 on the nursery stock 7 by acquiring the pressure data of the back pressure sensor 44, and may further control the extending lengths of the first back push rod 42 and the second back push rod 43, so as to avoid the tightening and the too loose of the back supporting bend 411 on the nursery stock 7.

In practice, the pressure range of the front pressure sensor 34 may be set in the control unit 6. When the front tightening mechanism 3 is tightened, the control unit 6 controls the first front push rod 32 and the second front push rod 33 to gradually extend so that the front hoop rope 31 tightens the nursery stock 7 until the pressure data of the front pressure sensor 34 reaches the minimum value of the set pressure range, and in the process, if the pressure of the front pressure sensor 34 exceeds the maximum value of the set pressure range, the control unit 6 controls the first front push rod 32 and the second front push rod 33 to stop extending and retract for a certain length so that the front hoop rope 31 loosens the nursery stock 7, and the pressure of the front pressure sensor 34 falls back into the set pressure range to finish tightening.

The pressure range of the rear pressure sensor 44 may be set in the control unit 6. When the rear tightening mechanism 4 is tightened, the control unit 6 controls the first rear push rod 42 and the second rear push rod 43 to gradually extend so that the rear hoop rope 41 tightens the nursery stock 7 until the pressure data of the rear pressure sensor 44 reach the minimum value of the set pressure range, and in the process, if the pressure of the rear pressure sensor 44 exceeds the maximum value of the set pressure range, the control unit 6 controls the first rear push rod 42 and the second rear push rod 43 to stop extending and retract for a certain length so that the rear hoop rope 41 loosens the nursery stock 7, and the pressure of the rear pressure sensor 44 falls back into the set pressure range to finish tightening.

In practical application, according to the related knowledge of force decomposition, the corresponding tension of the front hoop rope 31 is accurately calculated by using the pressure data of the front pressure sensor 34, but because the high precision is not needed, the corresponding relation between the pressure of the front pressure sensor 34 and the tension of the front hoop rope 31 can be tested and calibrated in advance, so that the set pressure range of the front pressure sensor 34 is determined. Similarly, the set pressure range of the rear pressure sensor 44 can be determined
