Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato planting and fertilization, in particular to a fertilization device for sweet potato planting. Background Art

[0002] Sweet potato refers to yam bean, a thick, twining herbaceous vine of the genus Yamica in the family Leguminosae. It has thick, oblate roots with hairs on the surface; feather-shaped leaves with veins and dark green color; small, polygonal flowers with many petals and light purple or light red corolla; large fruits with purple or light brown skin; flowering period is April-June; fruiting period is July-August.

[0003] Sweet potatoes need to be fertilized during their growth period. Currently, when fertilizing, one needs to squat down and use their hands to push aside the leaves to find the root position of the fruit before putting the fertilizer in. The applicant found that this requires squatting and walking on the ground for a long distance, which is too laborious. For this reason, we propose a fertilizing device for sweet potato planting, which can stand and push aside the leaves to find the root position of the fruit, and can accurately fertilize the root position of the fruit.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As mentioned in the background art, in order to solve the problem that fertilizing in the prior art is too laborious, the present invention provides a fertilizing device for sweet potato planting. Example

[0024] Reference Figures 1 to 4 A fertilizing device for sweet potato planting includes a long tube 1, a handle 2 is provided on the top of the long tube 1;

[0025] The top end of the side of the long tube 1 is connected to a connecting tube 3, and the top of the connecting tube 3 is connected to a fertilizer cylinder 4. Fertilizer particles are poured into the fertilizer cylinder 4, and the fertilizer particles can enter the long tube 1 through the connecting tube 3;

[0026] The bottom of the inner wall of the long tube 1 is detachably connected to a blocking block 5 so that the fertilizer can be blocked by the blocking block 5;

[0027] Feeding holes 6 are evenly and circumferentially opened at the bottom of the outer wall of the long tube 1;

[0028] A sleeve 7 is sleeved on the bottom of the outer wall of the long tube 1 to block the feed hole 6;

[0029] The sleeve 7 is connected to the lifting assembly so that the sleeve 7 no longer blocks the feed hole 6;

[0030] The lifting assembly is connected to the pressing assembly, and the pressing assembly is located around the handle 2 to facilitate the user to press.

[0031] An outer tube 8 is provided at the bottom of the long tube 1, and the block 5 is fastened to the outer tube 8 by threads. A rotating plate 9 is provided at the bottom of the block 5, and the rotating plate 9 is located below the outer tube 8. By rotating the rotating plate 9, the block 5 can be rotated easily. When the long tube 1 needs to be cleaned, the block 5 can be removed.

[0032] The top of the block 5 is in a conical structure, and the feeding hole 6 is arranged to be tilted downward, which makes it easier to quickly feed.

[0033] The lifting assembly includes a connecting block 10 arranged on the outside of the sleeve 7, a pull rod 11 is arranged on the top of the connecting block 10, a mounting block 12 and a rack 13 are arranged on the pull rod 11, the pull rod 11 vertically passes through the fixed plate 14, the pull rod 11 is slidably connected to the fixed plate 14, and the fixed plate 14 is fixedly set on the long tube 1, and a spring 15 is arranged between the fixed plate 14 and the mounting block 12. The spring 15 is arranged close to the top of the long tube 1 so that the spring 15 will not be contacted when the long tube 1 is used to push the blades away, thereby improving the service life of the spring 15. Example

[0034] Reference Figure 1 and Figure 4 The pressing assembly includes a gear 16 meshing with the rack 13, and a rotating shaft 17 is provided on the gear 16. The rotating shaft 17 is connected to a bearing seat 18 provided on the handle 2 through a bearing. A rack 2 19 is meshing with the gear 16, and the rack 2 19 is slidably sleeved on the guide rod 20, and the guide rod 20 is provided on the handle 2. A pressing rod 21 is provided on the rack 2 19, and the pressing rod 21 has an L-shaped structure, so that a pressing portion 22 can be provided on the side of the pressing rod 21 close to the handle 2, so that the user can press the pressing portion 22 with the thumb when holding the handle 2.

[0035] The rest of the structure is the same as that of Example 1.

[0036] Fertilizer granules are filled in the fertilizer barrel 4. The fertilizer granules can enter the long tube 1 through the connecting tube 3 and then into the discharge hole 6, where they are blocked by the blocking block 5 and the sleeve 7. Then, the long tube 1 is taken up by the handle 2 and entered into the sweet potato planting position. The leaves on the ground can be stood up to push away the leaves and find the position of the fruit root blocked by the leaves. Then, the user presses the pressing part 22 with his thumb to make the rack 2 19 drive the gear 16 to rotate, thereby driving the rack 13 to move upward, so that the pull rod 11 drives the mounting block 12 and the connecting block 10 to move upward, so that the spring 15 is compressed, and drives the sleeve 7 to move upward along the outer wall of the long tube 1, thereby exposing the discharge hole 6, so that the fertilizer granules in the long tube 1 can be automatically discharged to the fruit root. When the fertilization is completed, the pressing part 22 is released, the spring 15 is reset, and the rack 13 is pulled downward to make the sleeve 7 automatically move downward to block the discharge hole 6. Repeat the above steps to carry out multiple fixed-point fertilization in the sweet potato planting area.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
