DETAILED DESCRIPTION

[0018] The utility model is further described below.

[0019] The utility model provides an agricultural dotting device, which is mainly used for making holes on the land for planting seedlings, and comprises a driving frame 1 and a dotting roller 2. A rotating shaft 2 is provided at the center of the dotting roller 2, and the rotating shaft 2 is rotatably connected to the driving frame 1; it also comprises a dotting belt 3, which is in the shape of an elongated strip and has dotting holes 31 evenly arranged thereon, and dotting vertical rods 4 are arranged in the dotting holes 31, and locking pieces 5 are also provided at both ends of the dotting belt 3. The dotting belt 3 is arranged around the dotting roller 2 and is fixed by the locking piece 5, and the dotting vertical rod 4 is arranged on the dotting belt 3 along the radial direction of the dotting roller 2.

[0020] like Figure 1As shown, the agricultural dotting device includes a driving frame 1 and a dotting roller 2. The dotting roller 2 is rotatably connected to the driving frame 1 via a rotating shaft 2 arranged at the center of the dotting roller 2, so that the driving frame 1 drives the dotting roller 2 to rotate; the driving frame 1 can be connected to an existing walking drive mechanism to drive the dotting roller 2 to rotate, or it can be directly driven by manpower. The dotting roller 2 is provided with a dotting belt 3. When not in use, the dotting belt 3 is in the shape of a long strip, and dotting holes 31 are evenly spaced thereon. The spacing and number of the dotting holes 31 can be set according to the longitudinal spacing required for the seedlings to be planted; a dotting vertical rod 4 is set in the dotting hole 31, and the diameter of the dotting vertical rod 4 is the same as the aperture of the seedling planting hole required for the seedling, and the soil is drilled with the dotting vertical rod 4. When the dotting belt 3 is arranged around the dotting roller 2, the dotting vertical rod 4 is arranged on the dotting belt 3 along the radial direction of the dotting roller 2, as shown in FIG. This arrangement ensures that when the dotting vertical rod 4 rotates with the dotting roller 2 and penetrates into the soil, the drilled seedling planting holes are vertically shaped to facilitate seedling planting. The spacing of the dotting holes 31 is adjusted to adjust the spacing of the dotting vertical rods 4, thereby adjusting the longitudinal spacing of the seedling planting holes drilled by the agricultural dotting device, so that the agricultural dotting device can be adapted to the longitudinal spacing required by different seedlings. It should be noted that the dotting vertical rods 4 can be set one by one in the dotting holes 31, or they can be set at intervals in the dotting holes 31 according to actual punching requirements to meet the longitudinal spacing required by different seedlings. Locking pieces 5 are provided at both ends of the dotting belt 3 so that the dotting belt 3 can be arranged around the dotting drum 2. The above-mentioned locking pieces 5 can adopt an existing snap lock structure or a buckle lock structure; since the dotting belt 3 can be fixed by the locking pieces 5 and can be movably installed on the dotting drum 2, the installation positions of adjacent dotting belts 3 can be set according to the actual lateral spacing required by the seedlings. The spacing between adjacent dotting belts 3 is the lateral spacing of the seedling holes punched by the agricultural dotting device, so that the agricultural dotting device can be adapted to the lateral spacing required by different seedlings. To summarize, by using the agricultural dotting device, a dotting belt 3 which is arranged on the dotting roller 2 and is surrounded by a locking piece 5 is provided on the dotting roller 2, so that the lateral spacing required by different seedlings can be met by adjusting the spacing between the dotting belts 3, and then the dotting vertical rods 4 are arranged in the dotting holes 31 evenly arranged on the dotting belt 3, and the longitudinal spacing required by different seedlings can be met by adjusting the spacing of the dotting vertical rods 4 arranged on the dotting holes 31, that is, the agricultural dotting device can realize arbitrary adjustment of the seedling spacing in daily production.The dotting belt 3 can also be added to an existing agricultural planting dotting device as recorded in CN219876848U. The dotting head of the agricultural planting dotting device is passed through the dotting hole 31 on the dotting belt 3, and then the dotting belt 3 is fixed on the dotting wheel. By adding a dotting vertical rod 4 in the dotting hole 31 between adjacent dotting heads, the spacing between adjacent dotting heads originally located at the same cross section of the dotting wheel can be adjusted to achieve the longitudinal spacing of the seedling holes. The dotting belt 3 can also be directly added to the agricultural planting dotting device to adjust the spacing between adjacent dotting heads located on different cross sections of the dotting wheel to achieve the lateral spacing of the seedling holes. With this arrangement, there is no need to replace the dotting device, and it can also be applied to different planting spacing requirements of seedlings. The operation is convenient and the cost is low, so the purpose of universal application is achieved.

[0021] To save costs and facilitate installation and operation, Figure 2 , Figure 3 As shown, the locking member 5 includes a bolt 51, and the locking member 5 includes a bolt 51. The bolt 51 is fixedly arranged at one end of the dotting belt 3, and the bolt 51 extends toward the side away from the dotting belt 3. The other end of the dotting belt 3 is fixedly provided with a sleeve 52 for the bolt 51 to pass through, and one end of the bolt 51 passing through the sleeve 52 is threadedly connected with a nut 53.

[0022] In order to make the vertical rod 4 easily penetrate into the soil, drilling is performed, such as Figure 1 As shown, the end of the dot-marking vertical rod 4 away from the dot-marking roller 2 is provided with a tip portion 41. By providing the tip portion 41, the dot-marking vertical rod 4 can easily penetrate into the soil when the dot-marking roller 2 rotates to drill the seedling holes.

[0023] In order to facilitate the adjustment of the installation position of the dotting vertical rod 4, the dotting vertical rod 4 can be detachably arranged in the dotting hole 31, and can be specifically connected by threading, that is, the dotting hole 31 is set as a threaded hole, and the dotting vertical rod 4 is threadedly connected to the dotting hole 31. However, since the dotting belt 3 needs to be in a thin sheet shape so as to be arranged around the dotting roller 2, it is difficult to set the dotting hole 31 as a threaded hole. Therefore, as a preferred method, Figure 2 , Figure 3As shown, the dotting vertical rod 4 is a threaded rod 42, one end of the threaded rod 42 is provided with a screw head 421 with a diameter larger than the diameter of the dotting hole 31, the other end of the threaded rod 42 extends along the radial direction of the dotting roller 2 and passes through the dotting hole 31, and one end of the threaded rod 42 passing through the dotting hole 31 is threadedly connected with a fastening nut 422; by setting the screw head 421 with a diameter larger than the dotting hole 31, it is avoided that the threaded rod 42 slips out of the dotting hole 31 when setting it, and when the threaded rod 42 is fixed to the dotting belt 3 by using the fastening nut 422, when the installation position of the threaded rod 42 needs to be changed, the fastening nut 422 can be screwed off the threaded rod 42, thereby achieving the purpose of adjusting the installation spacing of the dotting vertical rod 4 according to the required longitudinal spacing of different seedlings, and the threaded rod 42 and the fastening nut 422 are low in cost and easy to obtain.

[0024] To control the drilling depth of the dotting tool, Figure 3 As shown, the threaded rod 42 also includes a first gasket 423, which is arranged between the dotting belt 3 and the screw head 421. By changing the thickness of the first gasket 423 located between the bottom of the dotting belt 3 and the dotting roller 2, the length of the exposed threaded rod 42 extending out of the dotting belt 3 is controlled, thereby achieving the purpose of controlling the drilling depth of the dotting device to adapt to the planting requirements of different seedlings.

[0025] To adapt to the different diameters of holes required by different seedlings, such as Figure 3 As shown, the threaded rod 42 also includes a hole expansion portion, and the hole expansion portion includes a first nut 424, a second nut 425 and a second gasket 426. The first nut 424 and the second nut 425 are sequentially arranged at the end of the threaded rod 42 away from the dotting roller 2 and are close to each other, and the second gasket 426 is arranged between the first nut 424 and the second nut 425. By arranging the first nut 424 and the second nut 425 at the top of the threaded rod 42, and arranging a second gasket 426 between the first nut 424 and the second nut 425, by changing the shape and size of the second gasket 426, the shape and size of the hole drilled by the dotting device can be changed to adapt to the requirements of drilling holes of different apertures required for different seedlings.

[0026] To facilitate the determination of the initial installation point of the dotted belt 3, Figure 4 As shown, one end of the dotting roller 2 is provided with dotting columns 6 evenly arranged around the circumference of the dotting roller 2; when installing the dotting belt 3, the dotting columns 6 already arranged on the dotting roller 2 can be passed through the dotting holes 31, so that the dotting belt 3 is arranged around the dotting roller 2, and then this is used as the initial point position, and the remaining dotting belts 3 are installed at equal intervals.
