[0002] Papaya is an evergreen, soft-wooded shrub or small tree belonging to the Caricaceae family and the Caricaceae genus. The plant can reach a height of 10 meters. When ripe, the papaya fruit is orange-yellow or yellow, oblong-spherical, obovate-oblong, pear-shaped, or nearly spherical. The flesh is soft, juicy, and sweet. It contains numerous ovoid seeds. Flowering and fruiting occur year-round. Ripe papaya fruit can be eaten as a fruit, while unripe fruit can be cooked or pickled as a vegetable. It can be processed into candied fruit, juice, jam, preserves, and canned goods. The seeds can be pressed for oil, and both the fruit and leaves have medicinal uses.

[0003] In the process of papaya cultivation, it is often necessary to germinate the seeds to obtain seedlings. However, the low winter temperatures cause many overwintering seedlings to suffer from frost damage. If appropriate measures are not taken in time, it will affect the growth of the seedlings the following year. In the current technology, when protecting papaya seedlings, workers usually wrap the trunk with insulating cloth. This method has poor insulation effect and is also easy to damage the seedlings during wrapping. Therefore, we propose a papaya seedling frost protection device to solve the above problems.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a frost protection device for papaya seedlings, including a top plate 1. The bottom edge of the top plate 1 is fixedly connected to one end of a plurality of support columns 3. The other ends of the plurality of support columns 3 are fixedly connected to the top edge of the bottom plate 4. The top of the bottom plate 4 is coaxially rotatably connected to one end of a threaded rod 12. The other end of the threaded rod 12 is fixedly connected to an adjustment knob 2. The adjustment knob 2 is coaxially rotatably connected to the top plate 1. The threaded rod 12 is sleeved with an adjustment plate 5 through a threaded structure. The adjustment plate 5 is movably disposed between the top plate 1 and the bottom plate 4. The adjustment plate 5 is slidably engaged with the support columns 3 respectively.

[0024] The arc-shaped outer walls of the adjusting plate 5 and the base plate 4 are respectively fixedly connected to one end of multiple adjusting components 6. The other end of the multiple adjusting components 6 is respectively fixedly connected to one end of the connecting rod 7. The other end of the connecting rod 7 is respectively hinged to the hinge seat 9. One end of the hinge seat 9 is fixedly connected to the end of the support rod 10. The inner side walls of the support rod 10, the connecting rod 7 and the bottom wall of the base plate 4 are respectively fixedly connected to foldable heat-insulating cloth 11. Example

[0025] Reference Figure 1-4This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, one end of the connecting rod 7 is provided with a hinge interface 71. The hinge interface 71 is connected to a positioning bolt 8 through a threaded structure. The positioning bolt 8 is rotatably connected to the hinge seat 9. After the opening and closing size of the connecting rod 7 is adjusted, the positioning bolt 8 is manually loosened so that the hinge seat 9 is disengaged from the hinge interface 71. At this time, the support rod 10 can rotate. The support rod 10 rotates to a vertical position, and then the positioning bolt 8 is manually tightened so that the hinge seat 9 abuts against the hinge interface 71. At the same time, anti-slip teeth can be provided at the abutment position to improve the friction at the contact position. The position of the hinge seat 9 is fixed by the friction.

[0026] Specifically, the adjusting plate 5 has multiple limiting slides 51 on its periphery, and the multiple limiting slides 51 are respectively slidably engaged with the support columns 3. The multiple support columns 3 are evenly distributed around the circumference. By sliding and engaging with the support columns 3 through the limiting slides 51, the adjusting plate 5 can move linearly and avoid rotating with the threaded rod 12.

[0027] Specifically, the adjustment assembly 6 includes an adjustment seat 61, an adjustment connecting rod 62, a transmission seat 63, a support seat 64, a connecting seat 65, and a mounting plate 66. One end of the adjustment seat 61 is fixedly connected to the arc-shaped outer wall of the adjustment plate 5, and the other end of the adjustment seat 61 is hinged to one end of the adjustment connecting rod 62. The other end of the adjustment connecting rod 62 is hinged to the transmission seat 63. The transmission seat 63 is fixedly connected to one side of one end face of the mounting plate 66, and the other side of one end face of the mounting plate 66 is fixedly connected to the connecting seat 65. The connecting seat 65 is hinged to the support seat 64, and the support seat 64 is fixedly connected to the arc-shaped outer wall of the base plate 4.

[0028] Furthermore, the other end of the mounting plate 66 is fixedly connected to the end of the connecting rod 7, the adjusting components 6 are evenly distributed around the circumference, the foldable heat insulation cloth 11 is made of inner non-woven fabric and outer breathable Oxford cloth, the two layers are sewn together, and the foldable heat insulation cloth 11 is fixedly sewn to the inner side wall of the support rod 10 and the connecting rod 7 and fixedly bonded to the bottom wall of the base plate 4.

[0029] When not in use, the connecting rod 7 is arranged in a vertical structure, with its length aligned with the length of the support column 3. The support rod 10 is also aligned with the connecting rod 7. This allows the entire device to be stored in a cylindrical structure, further reducing the overall footprint and making it easier to store.

[0030] Specifically, a conical head 101 is fixedly connected to the end of the support rod 10 away from the hinge seat 9. The isomorphic conical head 101 is inserted into the soil where the papaya seedlings are planted to support and fix the entire device.

[0031] The working principle and process are as follows: Based on the size of the papaya seedling, manually rotate the adjustment knob 2. The adjustment knob 2 drives the fixed threaded rod 12 to rotate. The threaded rod 12, through its threaded structure, drives the adjustment plate 5 to move between the top plate 1 and the bottom plate 4. The adjustment plate 5 drives the adjustment component 6 to work. The adjustment component 6 is a linkage mechanism, which drives the connecting rod 7 to swing around the hinge point of the support seat 64 and the connecting seat 6, thereby changing the opening and closing size of the connecting rod 7. This allows for adjustment of the diameter according to the size of the papaya seedling, facilitating the warming operation of papaya seedlings of different sizes. When adjusting the opening and closing size of the connecting rod 7, the foldable insulating cloth 11 simultaneously changes its opening size, forming a bronze bell-shaped dome. A gap is left between the bottom plate 4 and the connecting rod 7, allowing for folding and warming. The cloth 11 is not fixedly connected to the adjusting component 6, and the hinge interface 71 is also not fixedly connected to the foldable insulating cloth 11. This is to avoid damage to the foldable insulating cloth 11 when the adjusting component 6 and the hinge seat 9 are adjusted. After the connecting rod 7 is adjusted, the positioning bolt 8 is manually loosened so that the hinge seat 9 is disengaged from the hinge interface 71. At this time, the support rod 10 can rotate. The support rod 10 is rotated to a vertical position. Then, the positioning bolt 8 is manually tightened so that the hinge seat 9 abuts against the hinge interface 71. At the same time, anti-slip teeth can be set at the abutment position to increase the friction at the contact position. The friction fixes the position of the hinge seat 9. Finally, the foldable insulating cloth 11 is covered over the papaya seedling, and the conical head 101 is inserted into the soil to keep the papaya seedling warm and protected.

[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
