Description

Technical Field

[0001] The utility model belongs to the technical field of planting oxtail vetch in bags, and in particular relates to a plug-in type oxtail vetch sowing device. Background Art

[0002] Oxtail vetch is a kind of wild yam. At present, planting oxtail vetch in eco-bags is an innovative planting technology. Due to the limitation of eco-bags, oxtail vetch cannot grow vertically underground and can only grow horizontally along the extension direction of the eco-bag. Therefore, when digging and harvesting oxtail vetch, there is no need to dig a lot of soil downwards, but only to remove the loose soil in the eco-bag to expose the oxtail vetch tubers for harvesting, which saves a lot of digging workload and is convenient and efficient. However, when sowing, traditional yam sowing equipment can no longer be used. It can only be done by manually digging holes in the nutrient soil in the bag at the mouth of the eco-bag and then burying the oxtail vetch seeds. At present, there is still a lack of an effective auxiliary sowing device for planting oxtail vetch in eco-bags, and the sowing efficiency is not high. Utility Model Content

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figures 1 to 3 As shown, the utility model provides a plug-in type cowtail seeding device, which includes a planting tube 1 with openings at both ends, the lower end of the planting tube 1 is set as a wedge-shaped end for inserting bulky nutrient soil, and the wedge-shaped end is rotatably connected to a cover body 2 for blocking or opening the lower end opening of the planting tube 1, a handle 3 is fixedly provided on the outer wall of the upper end of the planting tube 1 in a radially symmetrical manner, and the lower surfaces of the two handles 3 are correspondingly provided with a light rod 4 extending downward, and the two light rods 4 are slidably connected to the same connecting block 5, and the lower end of the light rod 4 is connected to an anti-falling block 6, and the connecting block 5 Pull rods 7 corresponding to the upper and lower parts of the handle 3 are symmetrically provided on the left and right sides. A compression spring 8 is sleeved on the light rod 4. The upper end of the compression spring 8 is pressed against the lower surface of the handle 3, and the lower end is pressed against the upper surface of the pull rod 7. The front side of the connecting block 5 is transmission connected with the cover body 2 through a connecting rod mechanism. When the pull rod 7 is pulled upward, the connecting rod mechanism drives the cover body 2 to rotate and open the lower end opening of the planting tube 1. After the pull rod 7 is released, the compression spring 8 pushes the pull rod 7 to move downward, and the connecting rod mechanism pushes the cover body 2 to automatically reset and close the lower end opening of the planting tube 1.

[0022] It should be noted that if Figure 1As shown in the figure, when using the above device for sowing the tubers of Hedysarum polybotrys Hand.-Mazz., the planting tube 1 should be inserted into the nutrient soil in the lower part of the ecological bag slightly obliquely from the bag mouth of the ecological bag. The depth of the lower end of the planting tube 1 entering the nutrient soil is more than 25 cm. After insertion, a planting groove is formed in the nutrient soil. The length of the tuber is preferably 10-15 cm. After insertion, the tuber is put into the planting tube 1 from the upper opening. Then, the planting tube 1 is slightly lifted (about 3-5 cm) to make the cover body 2 not tightly abut against the bottom of the planting groove. Then, both hands pull the pull rod 7, and the cover body 2 will rotate and open accordingly. The tuber slides out from the lower end of the planting tube 1 and enters the planting groove. Keep the action of holding the pull rod 7 with the hand and continue to lift the planting tube 1, then the tuber completely slides out of the planting tube 1 and enters the planting groove. While lifting, the planting tube 1 is rotated left and right by about 30 degrees, and the link mechanism will loosen the nutrient soil on the side wall of the planting groove. Every time the planting tube 1 is lifted by a section, nutrient soil will be backfilled into the planting groove. When the planting tube 1 is completely lifted out of the nutrient soil, the planting groove is basically completely backfilled, and the tuber is well covered and the planting depth is good. In order to make the sowing quality higher, scale marks can be set on the outer wall of the planting tube 1 to guide the depth of insertion into the nutrient soil and the degree of extraction during subsequent extraction in sections.

[0023] In an embodiment of the present invention, the link mechanism includes an upper hinge piece 9, a connecting rod 10, and a lower hinge piece 11. The cover body 2 is provided with a convex joint 12 protruding downward beyond the outer wall of the planting tube 1 on the front side of the upper part. The upper end of the connecting rod 10 is hinged to the front side of the connecting block 5 through the upper hinge piece 9, and the lower end of the connecting rod 10 is hinged to the convex joint 12 through the lower hinge piece 11.

[0024] It should be noted that the connecting rod 10 of the link mechanism cooperates with the upper and lower hinge pieces 11. When the connecting block 5 moves up and down, the connecting rod 10 can well push and pull the cover body 2 to rotate, so as to achieve the purpose of blocking or opening the lower end opening of the planting tube 1. The connecting rod 10 also plays a role in scraping and loosening the nutrient soil on the inner wall of the planting groove when the planting tube 1 rotates in the nutrient soil.

[0025] In an embodiment of the present invention, the upper part of the cover body 2 is fixedly provided with an upper convex block 13 extending upward. The left and right sides of the upper convex block 13 are rotationally connected to the two side walls of the connecting groove opened at the lower end of the barrel wall of the planting tube 1 through a pin shaft 14.

[0026] It can be understood that the cover body 2 should be made of a hard material, such as steel or hard plastic. When it blocks the lower end of the planting tube 1, it can prevent the nutrient soil from entering the planting tube 1 during the downward insertion process.

[0027] In an embodiment of the present utility model, the planting cylinder 1 is a cylindrical cylinder or a square cylinder, and the connecting block 5 is semi-circular or U-shaped. When it is a cylindrical cylinder, the corresponding cover body 2 is an elliptical cake shape, and when it is a square cylinder, the corresponding cover body 2 is a rectangular plate shape. In addition to being semi-circular or U-shaped, the connecting block 5 can also be a sleeve ring similar to the shape of the planting cylinder 1.

[0028] In an embodiment of the present utility model, a guide wheel 15 is rotatably connected to the side of the front side of the connecting block 5 facing the outer wall of the front side of the planting cylinder 1. The guide wheel 15 is pressed against the outer wall of the front side of the planting cylinder 1. When the connecting block 5 moves up and down relative to the planting cylinder 1, the guide wheel 15 rolls on the outer wall of the front side of the planting cylinder 1.

[0029] It can be understood that the guide wheel 15 can play a certain role in support and friction reduction, ensuring that the connecting block 5 can smoothly and smoothly move upward along the planting cylinder 1 when the pull rod 7 is pulled.

[0030] In an embodiment of the present utility model, the handle 3 and the pull rod 7 are arranged in a cylindrical shape that is convenient to hold on the side away from the planting cylinder 1. To avoid abrasion of the hand due to frequent operation, a flexible rubber sleeve can be sleeved on the handle 3 and the pull rod 7.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
