Description

Technical Field

[0001] The utility model relates to the technical field of seedling transplanting, in particular to a seedling transplanting survival period anti-lodging device. Background Art

[0002] The best time to transplant seedlings is during their dormancy period, which is usually from October in autumn to April in the following spring. Since the rooting stability of seedlings is poor after transplanting, transplanted seedlings usually need to be protected from lodging by anti-lodging facilities.

[0003] The existing anti-lodging structure usually adopts a supporting anti-lodging structure that can support the branches and trunks of seedlings to remain vertical. Although the existing anti-lodging structure can maintain the vertical growth state of the main trunk of the seedling, it has a vertical upward component when supporting the main trunk of the seedling, which makes the existing supporting anti-lodging structure not conducive to forming a firm grip between the roots of the seedlings and the soil. For this reason, we propose an anti-lodging device for seedlings during transplanting and survival period, which can ensure that the roots of the seedlings are in full contact with the soil and is conducive to the rapid rooting of the seedlings after transplanting.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 5 The figure shows a traditional anti-lodging structure. The traditional anti-lodging structure L generates an oblique upward supporting force f on the main trunk P of the seedling. The supporting force f can be decomposed into a vertical upward component f1 and a horizontal component f2. When the anti-lodging structure L generates an opposite component f2 in the horizontal direction, the horizontal components can offset each other. Since the vertical component f1 is opposite to the growth direction of the root system, the traditional anti-lodging structure L is not conducive to maintaining the grip of the seedling roots on the ground.

[0023] See also Figure 1-Figure 4The utility model provides a technical solution: a lodging resistance device for seedlings during transplantation and survival period, comprising symmetrically distributed holding blocks 1, which can maintain full contact between the root system of the seedlings and the soil by applying a thrust with a balanced force component in the horizontal direction and a force component in the vertical downward direction to the main trunk P of the seedlings, which is beneficial to the full growth of the root system of the seedlings, strengthens the grip of the seedlings on the ground, and thus promotes the survival rate of the seedlings after transplantation. A cylindrical cavity is formed in the middle of the symmetrically distributed holding blocks 1, and the cylindrical cavity is tangent to and penetrates the main trunk P of the seedlings. An anti-slip pad 2 is welded on one side of the holding block 1. The anti-slip pad 2 can prevent the retaining block 1 from shifting on the surface of the seedling trunk P. The top of the retaining block 1 is detachably connected with a retractable connecting assembly, and the retractable connecting assembly includes a male positioning rod 6, which is fixed through the top of the retaining block 1, and the surface of the male positioning rod 6 is movably connected with a male connecting rod 7. A bayonet 10 is penetrated through the side of the male connecting rod 7, and the inside of the male connecting rod 7 is tangently connected with a female connecting rod 8 through the bayonet 10. One end of the female connecting rod 8 is movably penetrated with a female positioning rod 9, and the male connecting rod 7 can adjust the clamping depth between the male connecting rod 7 and the female connecting rod 8 along the bayonet 10.

[0024] The retractable connecting component detachably connects one end of adjacent retaining blocks 1 and can adjust its own length according to the distance between adjacent retaining blocks 1. Even if the trunks P of seedlings with different diameters are limited, the connection between adjacent retaining blocks 1 can be maintained. The surfaces of the symmetrical retaining blocks 1 are respectively connected with tensioning ropes 5 with cross-shaped tensioning directions. The tensioning ropes 5 apply a downward pulling force to the retaining blocks 1 to which they are connected and make the retaining blocks 1 hold the seedling trunks P tightly. The lower ends of the tensioning ropes 5 are fixed to the ground through a fixed structure.

[0025] The fixing structure includes a counterweight block 15 welded to the lower end of the tension rope 5. The internal thread of the counterweight block 15 is penetrated by a stud 16. The counterweight block 15 is conducive to improving the stability of the installation of the anti-lodging device.

[0026] Preferably, Figure 3 As shown, the anti-skid pad 2 is a rubber block with the ability to restore deformation. An arc surface 3 is provided on one side of the anti-skid pad 2. The height of the anti-skid pad 2 is not less than the height of the retaining block 1. The anti-skid pad 2 can increase the static friction of the contact part with the trunk P of the seedling.

[0027] Preferably, Figure 3 As shown, the top and bottom ends of the anti-slip pad 2 are respectively glued and connected with auxiliary anti-slip rods 4, the auxiliary anti-slip rods 4 are rubber rods with an arc, and the length of the auxiliary anti-slip rods 4 is not less than the width of the anti-slip pad 2, which is beneficial for the auxiliary anti-slip pad 2 to strengthen the friction between the retaining block 1 and the surface of the seedling trunk P.

[0028] Preferably, Figure 2As shown, the tops of the male connecting rod 7 and the female connecting rod 8 are respectively penetrated with a strip-shaped connecting hole 11, the inside of the strip-shaped connecting hole 11 is tangentially penetrated with a screw rod 12, the surface of the screw rod 12 is penetrated with a gasket 13, the surface of the screw rod 12 is threadedly connected with a locking nut 14, and the locking nut 14 presses the gasket 13 against the top surface of the female connecting rod 8 to prevent the male connecting rod 7 and the female connecting rod 8 from shifting.

[0029] Preferably, Figure 1 As shown, two pairs of retaining blocks 1 are provided, and the four retaining blocks 1 are symmetrical in pairs. The four retaining blocks 1 are connected with at least one pair of crossed and axially symmetrically distributed tensioning ropes 5, which can maintain the stability of the connection between the anti-lodging device and the trunk P of the seedlings.

[0030] Working principle: When in use, the anti-slip pad 2 and one side of the arc-shaped surface of the auxiliary anti-slip rod 4 are pressed against the surface of the seedling trunk P, so that the symmetrically connected tensioning rope 5 is tilted downward and tensioned. At this time, the tensioning rope 5 applies a downward traction force F on the retaining block 1, and F can be decomposed into a vertical downward component F1 and a horizontal component F2. When the symmetrical tensioning ropes 5 simultaneously apply traction to the seedling trunk P, the horizontal components generated are equal in magnitude and opposite in direction, thereby offsetting each other. At this time, the vertical downward force applied to the seedling trunk P is twice F1. The vertical downward force applied to the seedling trunk P can strengthen the connection with the ground compared to the traditional oblique upward support structure L, which is beneficial to improving the grip of the roots of the transplanted seedlings on the ground and promoting the survival rate of the seedlings after transplanting.
