DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1-Figure 5 As shown, a sweet potato seedling planting device comprises a shell 1 with a cavity inside, a planting tube 3 is inserted in the cavity, and the bottom end of the planting tube 3 is hinged with two symmetrically distributed cone plates 17, and driving parts for driving the two cone plates 17 to rotate and open are respectively arranged on both sides of the planting tube 3; handles 2 are also installed on both sides of the top of the shell 1; a seedling adding bucket 4 is installed on the top of the planting tube 3, and a cover plate for sealing the top of the shell 1 is sleeved on the top of the seedling adding bucket 4;

[0025] The outer shell 1 is also provided with an elastic structure for facilitating the lifting and lowering of the planting tube 3, and the elastic structure includes a first movable groove 14 opened on both sides of the outer shell 1, and a movable block 11 fixed on both sides of the planting tube 3, and a fixed block 13 is installed at the bottom of the two first movable grooves 14, and a second spring 12 is connected between the fixed block 13 and the movable block 11, one end of the movable block 11 is in the first movable groove 14, and pedals 10 are connected to both sides of the bottom end of the planting tube 3, and the two pedals 10 are respectively located on both sides of the outside of the outer shell 1, and second movable grooves 15 for lifting and lowering the pedals 10 are opened on both sides of the bottom of the outer shell 1.

[0026] Specifically, Figure 1-Figure 5 As shown, the driving member includes a first connecting ear fixed on the outer wall of the planting tube 3, and a second connecting ear installed on the side wall of the cone plate 17, a pressure plate 5 is hinged on the first connecting ear, and a main connecting rod 7 is hinged at the bottom of the pressure plate 5, a secondary connecting rod 8 is hinged at the bottom end of the main connecting rod 7, and the bottom end of the secondary connecting rod 8 is hinged to the second connecting ear, a first spring 6 is connected between the bottom of the pressure plate 5 and the side wall of the planting tube 3, and slots 16 for adjusting the main connecting rod 7 are also opened on both sides of the outer shell 1.

[0027] When planting sweet potato seedlings, the planting personnel can carry the planting device to the sweet potato planting site through the handle 2, and then step on the two pedals 10 to move the planting tube 3 downward along the cavity inside the outer shell 1 until the cone plate 17 at the bottom of the planting tube 3 is inserted into the soil. At this time, the moving block 11 descends along the first moving groove 14 driven by the planting tube 3, and squeezes the second spring 12 to shrink the second spring 12. Then the planting personnel pulls the pressure plates 5 on both sides of the outer shell 1 upward. At this time, the pressure plate 5 rotates with the planting tube 3 and stretches the first spring 6, so that the pressure plate 5 drives the two cone plates 17 to rotate and open through the cooperation of the main connecting rod 7 and the auxiliary connecting rod 8 (such as Figure 3As shown), the soil is expanded to form a planting pit, and then the planting personnel add the sweet potato seedlings from the seedling bucket 4 into the planting tube 3, so that the sweet potato seedlings fall from the planting tube 3 into the planting pit. Finally, the planting personnel release the pedal 10 with their feet. At this time, the second spring 12 pushes the moving block 11 upward, causing it to rise along the first moving groove 14, and drives the planting tube 3 to rise and reset along the outer shell 1. At this time, the planting tube 3 drives the cone plate 17 to collect in the outer shell 1, and then the planting personnel move the planting device to the next planting location to complete the planting of the sweet potato seedlings. After planting, the pressing plate 5 can be loosened, so that the pressing plate 5 rotates downward and resets under the action of the first spring 6, so as to drive the two cone plates 17 to rotate and close together.

[0028] Furthermore, if Figure 2 , Figure 4 and Figure 5 As shown, a connecting plate is connected between the pedal 10 and the planting tube 3, and a plurality of positioning nails 18 are installed at the bottom of the connecting plate.

[0029] When the planting personnel step on the pedal 10 to move the planting tube 3 downward, the pedal 10 will drop synchronously. At this time, the positioning pins 18 at the bottom of the connecting plate can be inserted into the soil to assist in positioning the device and avoid the device from tilting, which is beneficial to the planting of sweet potato seedlings.

[0030] In addition, in one embodiment, if Figure 1-Figure 5 As shown, a cleaning structure 9 for cleaning the two cone plates 17 is provided at the bottom of the housing 1, and the cleaning structure 9 includes mounting plates 91 arranged on both sides of the bottom of the inner wall of the housing 1, and a plurality of cleaning strips 92 are installed on the opposite sides of the two mounting plates 91.

[0031] After the planting is completed, when the planting tube 3 rises inside the outer shell 1 under the action of the second spring 12, the cone plate 17 is retracted into the outer shell 1 as the planting tube 3 rises. At this time, the cleaning strips 92 on one side of the two mounting plates 91 can clean the outer walls of the two cone plates 17 to avoid residual dirt on the outer walls of the cone plates 17 and prevent scaling on the outside of the cone plates 17, thereby facilitating the subsequent use of the cone plates 17.

[0032] Furthermore, if Figure 4 and Figure 5 As shown, mounting grooves 94 are provided on both sides of the bottom of the housing 1 , a mounting plate 91 is located in the mounting grooves 94 , and two locking screws 93 are screwed on the mounting plate 91 , and threaded holes matching the locking screws 93 are provided in the housing 1 .

[0033] When the brush strip 92 needs to be replaced, the locking screw 93 can be unscrewed first, and the mounting plate 91 can be pulled downward so that the mounting plate 91 is moved out of the mounting slot 94, so as to remove the brush strip 92 from the bottom of the shell 1, and then the brush strip 92 can be replaced. After the replacement, the mounting plate 91 can be inserted into the mounting slot 94, and the locking screw 93 can be screwed in to screw the mounting plate 91 and the shell 1 together to complete the installation of the brush strip 92, thereby realizing the rapid disassembly and assembly of the brush strip 92, facilitating the normal use of the brush strip 92, and facilitating the cleaning of the outer wall of the cone plate 17.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
