[0002] Seedlings cultivated by sowing or vegetative propagation have a high density and each seedling occupies a small nutritional space. To cultivate large seedlings, they must be transplanted. Depending on the requirements of landscape greening for seedlings of various specifications and the cultivation methods, they can be transplanted once or multiple times. Transplanting can expand the nutritional space for seedling growth, such as light space, ventilation space, and branch growth space, as well as the space for root growth, water absorption and nutrition. Pruning the roots during transplanting can also stimulate the development of the seedling root system, produce more fibrous roots, and improve the survival rate of greening.
[0003] When transplanting seedlings, in order to ensure that the roots at the bottom of the seedlings are not damaged, the soil around the roots at the bottom of the seedlings is generally dug out. Currently, the most commonly used tool for excavation is a shovel, but the front end of the shovel is relatively sharp for the roots of the seedlings. If the excavation process is not well controlled, it is easy to damage the roots of the seedlings and affect the survival rate of the seedlings. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a soil ball digging device for transplanting greening seedlings, which solves the problem that the front end of the shovel is relatively sharp for the roots of the seedlings, and if the digging process is not well controlled, it is easy to damage the roots of the seedlings and affect the survival rate of the seedlings.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 The utility model provides a technical solution: a soil ball excavating device for transplanting greening seedlings, comprising a cylindrical device frame 1, the bottom end of the device frame 1 is vertically fixedly connected to an extension frame 2 which is connected to the inside and is tubular, the inside of the device frame 1 is horizontally rotatably connected to a rotating disk 6, the front side surface of the rotating disk 6 is horizontally provided with a transverse groove 7 arranged along its radial direction, the inside of the transverse groove 7 is rotatably connected to a threaded rod 8 along its length direction, the outer surface of the threaded rod 8 is threadedly connected to a threaded sleeve 9, and the front end surface of the threaded sleeve 9 is horizontally fixedly connected to a connecting seat 10;
[0020] A sliding hole 3 is vertically penetrated at the bottom end of the extension frame 2, and a digging rod 4 is vertically slidably connected inside the sliding hole 3. The top end of the digging rod 4 is rotatably connected to a connecting rod 5, and the other end of the connecting rod 5 is rotatably connected to the outer surface of the connecting seat 10.
[0021] A motor 17 is fixedly connected to the rear end surface of the device frame 1 , and an output shaft of the motor 17 rotatably passes through the device frame 1 and is fixedly connected to the rear side surface of the rotating disk 6 .
[0022] When the device is in use, the motor 17 is first started. After the motor 17 is started, the rotation of its output shaft can drive the rotating disk 6 to rotate. During the rotation of the rotating disk 6, the connecting seat 10 on the front end surface of the rotating disk 6 will rotate synchronously with the rotating disk 6, and at the same time, it will also drive the upper end of the connecting rod 5 to move. The lower end of the connecting rod 5 is connected to the top of the digging rod 4 due to rotation, and the digging rod 4 is restricted by the sliding hole 3 to only move vertically, so the connecting rod 5 will drive the digging rod 4 to move up and down repeatedly. At this time, people place the digging rod 4 of the device on the ground and can break up and loosen the soil by repeatedly hitting the ground. Then people can shovel away the loosened soil and easily pull up the seedlings with their roots. The device will not cause damage to the root system of the seedlings during use, thereby ensuring the survival rate of the seedlings after transplanting.
[0023] An inner cavity is formed inside the rotating disk 6 , and a servo motor 13 is fixedly connected to the inner cavity. The output shaft of the servo motor 13 rotatably passes through the rotating disk 6 and is fixedly connected to one end of the threaded rod 8 .
[0024] The threaded rod 8 in the device can be driven to rotate by the output shaft of the servo motor 13. When the threaded rod 8 rotates, the threaded sleeve 9 on its surface will move along its length direction, thereby changing the distance between the threaded sleeve 9 and the center of the rotating disk 6. The change in the distance between the two can change the amplitude of the up and down movement of the digging rod 4, so that when the device encounters harder soil, it can increase the amplitude of the device's downward movement to quickly break up the soil, thereby improving the efficiency of the transplanting process.
[0025] The bottom end of the digging rod 4 is fixedly connected with a digging cone head 11, and the lower end of the outer surface of the digging rod 4 is fixedly connected with a plurality of digging blocks 12.
[0026] The digging cone head 11 is in an inverted cone shape, which can improve the digging efficiency. The digging block 12 can bring up a larger range of surrounding soil when the digging rod 4 of the device moves upward, which can also improve the digging efficiency of the device.
[0027] The top of the device frame 1 is fixedly connected with a device seat 18 , and both sides of the top of the device seat 18 are laterally fixedly connected with handles 20 , and the outer surfaces of the two handles 20 are both covered with anti-slip covers 21 .
[0028] A plurality of reinforcing ribs 19 are fixedly connected between the device seat 18 and the device frame 1 .
[0029] A connecting ring 14 is fixedly connected to the bottom end of the outer surface of the extension frame 2 , a footrest 15 is laterally fixedly connected to the outer surface of the connecting ring 14 , and an anti-slip pattern 16 is provided on the upper surface of the footrest 15 .
[0030] When using the device, people can step one foot on the foot pedal 15 and hold the two handles 20 with both hands to control the device, and use their own weight to prevent the device from jumping up, thereby ensuring the digging effect of the device.
[0031] When the device is in use, the motor 17 is first started. After the motor 17 is started, the rotation of its output shaft can drive the rotating disk 6 to rotate. During the rotation of the rotating disk 6, the connecting seat 10 on the front end surface of the rotating disk 6 will rotate synchronously with the rotating disk 6, and at the same time, it will also drive the upper end of the connecting rod 5 to move. The lower end of the connecting rod 5 is connected to the top of the digging rod 4 due to rotation, and the digging rod 4 is restricted by the sliding hole 3 to only move vertically, so the connecting rod 5 will drive the digging rod 4 to move up and down repeatedly. At this time, people place the digging rod 4 of the device on the ground and can break up and loosen the soil by repeatedly hitting the ground. Then people can shovel away the loosened soil and easily pull up the seedlings with their roots. The device will not cause damage to the root system of the seedlings during use, thereby ensuring the survival rate of the seedlings after transplanting.
