Technical Field

[0001] The utility model belongs to the technical field of agricultural planting, and in particular relates to a quick hole-punching device for stevia cuttings. Background Art

[0002] The economic benefits of stevia are considerable. Stevia sugar extracted from stevia is a new type of sweetener. Stevia sugar has the characteristics of high sweetness, low calories, pure natural and pollution-free. It is known as the world's third largest healthy sugar source and is suitable for beverages, food, medical and other industries. It is especially helpful for the treatment of diabetes and lowering blood pressure. It is also effective for obesity, heart disease, pediatric tooth decay, etc. It can promote metabolism and strengthen the body. The application prospects of stevia will be very broad.

[0003] At present, stevia can be propagated by sowing, cuttings, layering, division and other methods. Currently, field cuttings and punching are mainly done by hand with the help of tools. There is no systematic mechanical operation for stevia seedling cuttings and punching in China. Since it is mainly done by hand, it is not only labor-intensive but also inefficient. The benefits obtained are also greatly reduced, and intensive seedling cultivation cannot be formed. Therefore, traditional stevia seedling cuttings and punching cannot meet the existing market demand. Utility Model Content

[0026] Example 1

[0027] like Figure 1 As shown;

[0028] According to an embodiment of the utility model, a device for rapid hole punching for stevia cuttings comprises a hand-held handle 1 for pushing and punching.

[0029] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "Currently, stevia can be propagated by sowing, cuttings, layering, division and other methods. Currently, field cuttings and punching are mainly done manually with the aid of tools. There is no systematic mechanical operation for stevia seedling cuttings and punching in China. Since it is mainly done manually, it is not only labor-intensive but also inefficient, and the benefits obtained are greatly reduced, and intensive seedling cultivation cannot be formed. Then, traditional stevia seedling cuttings and punching cannot meet the existing market demand." In terms of actual use, this problem is obviously a real problem that is difficult to solve. Therefore, in order to solve this technical problem, a planting distance adjustment component 2, a left punching component 3 and a right punching component 4 are added on this basis.

[0030] like Figure 1-6 As shown in the figure;

[0031] In combination with the above content, in order to quickly perform the punching operation and facilitate the adjustment of the spacing between the two punched holes, it also includes a planting distance adjustment component 2 arranged at the bottom of the handle 1, and a left punching component 3 and a right punching component 4 arranged on the planting distance adjustment component 2;

[0032] The planting distance adjustment assembly 2 includes a U-shaped support 21 fixed to the handle 1, and a rotating rod 22 and a pair of guide rods 23 for guiding are arranged between the left and right ends of the U-shaped support 21 through bearings.

[0033] In an optional embodiment, the left and right ends of the rotating rod 22 are respectively provided with external threads with opposite thread directions, and the two ends of the rotating rod 22 are respectively screwed with a left support 24 and a right support 25, the left support 24 and the right support 25 are respectively fixedly connected to the left punching assembly 3 and the right punching assembly 4, the left support 24 and the right support 25 are both sleeved on the guide rod 23, and the left support 24 and the right support 25 both slide left and right on the guide rod 23, and a rotating handle 26 is installed at the right end of the U-shaped support 21, and the rotor of the rotating handle 26 is fixedly connected to the rotating rod 22.

[0034] In this embodiment: driving the rotating handle 26 drives the rotating rod 22 to rotate. Since the threads at both ends of the rotating rod 22 are in opposite directions, and the left support 24 and the right support 25 are respectively screwed on the threads in different directions at both ends of the rotating rod 22, the rotation of the rotating rod 22 drives the left support 24 and the right support 25 to move in opposite directions, thereby driving the left punching component 3 and the right punching component 4 to move closer to or away from each other, and adjusting the different distances between the two, which is convenient for punching operations with different planting distances, and has greater flexibility.

[0035] In an optional embodiment, the left punching assembly 3 and the right punching assembly 4 have the same structural size and are symmetrically arranged on the left and right sides. The left punching assembly 3 includes a sliding rod 31 fixed to the bottom of the left support 24, and a limiting support 32 sleeved on the sliding rod 31. A pressure plate 33 is fixed on the sliding rod 31 inserted into the limiting support 32. A spring 34 is sleeved on the sliding rod 31 at the bottom of the pressure plate 33. A limiting ring 35 that slides up and down is provided on the sliding rod 31. A locking bolt 36 is provided on the limiting ring 35. A plug 37 is fixed to the lower end of the sliding rod 31.

[0036] In this embodiment: the limit support 32 is fitted on the ground, and then the handle 1 is pressed to push the slide bar 31 to slide downward through the planting distance adjustment component 2. At this time, the slide bar 31 pushes the plug 37 to punch the ground. At the same time, the pressure plate 33 compresses the spring 34. After the punching is completed, the plug 37 inserted in the ground is automatically pulled out through the reaction force of the spring 34 to complete the punching operation. The limit ring 35 is slid on the slide bar 31 and limited by the locking bolt 36, and the distance from the limit ring 35 to the limit support 32 is adjusted, thereby adjusting the downward running distance of the plug 37, and finally adjusting the punching depth, so as to facilitate use according to different planting needs.

[0037] Working principle of this utility model:

[0038] The limit support 32 is placed on the ground, and then the handle 1 is pressed to push the slide bar 31 to slide downward through the planting distance adjustment component 2. At this time, the slide bar 31 pushes the plug 37 to punch the ground. At the same time, the pressure plate 33 compresses the spring 34. After the punching is completed, the plug 37 inserted in the ground is automatically pulled out through the reaction force of the spring 34 to complete the punching operation. The limit ring 35 is slid on the slide bar 31 and limited by the locking bolt 36 to adjust the distance from the limit ring 35 to the limit support 32, thereby adjusting the downward movement of the plug 37 The distance is adjusted, and the drilling depth is finally adjusted to facilitate different planting needs. The rotating handle 26 is driven to drive the rotating rod 22 to rotate. Since the threads at both ends of the rotating rod 22 are in opposite directions, and the left support 24 and the right support 25 are respectively screwed on the threads in different directions at both ends of the rotating rod 22, the rotation of the rotating rod 22 drives the left support 24 and the right support 25 to move in opposite directions, thereby driving the left punching component 3 and the right punching component 4 to move closer to or away from each other, and adjusting the different spacing between the two, which is convenient for punching operations at different planting distances, and has greater flexibility.

[0039] The above are only preferred embodiments of the present invention and are 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.
