Chinese patent No. CN205337074U discloses a tree supporting device, which comprises three supporting plates for fixing a trunk and three supporting rods respectively connected to the lower ends of the corresponding supporting plates; the three support plates are wound around the trunk in a triangular shape, a buffer is filled between each support plate and the trunk, two ends of each support plate are provided with fixing plates used for connecting adjacent support plates, and two ends of each adjacent support plate are connected through bolts penetrating through the fixing plates; the equal slope of three bracing piece sets up, and the upper end of every bracing piece all is connected to the backup pad that corresponds through the stiffener, and the lower extreme of every adjacent bracing piece all connects through the horizontal pole, and the lower extreme of every bracing piece all is equipped with the ground nail of grabbing that is fixed in ground.

The supporting plate and the supporting rod form a stable vertical structure and are clamped and reinforced by the supporting plate and a buffer object therein. The structure mainly has two conditions, namely, tight clamping, and under the condition, the supporting device can be tightly abutted and fastened with the tree, so that the structure has better windproof performance, but the growing space is limited. If the clamping force is reduced, a growth space is reserved, and the windproof performance of the composite material is greatly reduced; when the wind is strong, the trees may incline or swing to some extent, which affects the root fixing.

Disclosure of Invention

The invention aims to provide a tree supporting device, which achieves the effect of keeping reinforcement and meeting the growth space requirement of trees.

The technical purpose of the invention is realized by the following technical scheme:

a tree supporting device comprises a foot rest fixed on the ground and a righting mechanism fixed on the foot rest, wherein the righting mechanism comprises a base frame surrounding a tree, a push rod penetrating through the base frame in a threaded connection mode and a first wind wheel driving the push rod to rotate, a first winding wheel linked with the first wind wheel is arranged on one axial side of the first wind wheel, a first driven wheel linked with the first winding wheel in a winding mode is arranged on the push rod, and the push rod moves towards the direction of pressing the tree when the first driven wheel is driven; and a reset mechanism for driving the push rod to rotate and reset is also arranged between the push rod and the base frame.

By adopting the scheme, the foot rest is used as a basic fixing structure of the supporting device and is fixedly connected with the ground; the righting mechanism supports and fixes tree seedlings on the basis, the supporting and fixing are mainly completed through a plurality of push rods or the push rods matched with the base frame in an abutting mode, the push rods can be adjusted through threads, namely, the diameter of the clamp or the tightness of the clamp can be adjusted according to the growth condition of the seedlings, and the clamp can be always kept due to the axial self-locking of the thread transmission. That is to say, in practical use, the end part of the push rod can be pre-attached to the surface of the tree or be away from the surface of the tree by a small distance so as to provide a space for the growth of the tree; when the wind power is high, the first wind wheel can be driven to move towards the tree or further press the surface of the tree through the transmission push rod of the first winding wheel and the first driven wheel so as to increase the clamping effect on the tree, and the larger the wind power is, the larger the clamping force is; therefore, the trees can be effectively prevented from deflecting and toppling; after the wind power is reduced, the push rod can gradually rotate reversely and separate along with the action of the reset mechanism so as to reduce the clamping force, and the first driven wheel also rewinds; in conclusion, the scheme can be in the normal state need not to fasten trees completely to provide space for the growth of trees, can receive great when wind-force oppresses at trees, can improve the clamping-force to trees automatically again, maintain its planting state stability with the protection trees.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the present invention.

Example 1: a tree supporting device, as shown in fig. 1 and 3, comprises a foot rest 1 fixed on the ground, a righting mechanism 2 fixed on the foot rest 1, and a resetting mechanism 3 for resetting the righting mechanism 2.

Referring to fig. 1 and 2, the righting mechanism 2 includes a base frame 21, four push rods 22 and four first wind wheels 23 uniformly distributed on the base frame 21 along a circumferential direction, the push rods 22 and the first wind wheels 23 correspond to each other one by one, and ends of the push rods 22 face to a center of the base frame 21. Wherein, bed frame 21 surrounds trees and is fixed connection with foot rest 1, and bed frame 21 is divided into two parts along radial, and passes through the bolt fastening. The base frame 21 is provided with a through hole 28 for the push rod 22 to pass through, and the through hole 28 is provided with a second threaded portion 281 and a stop ring 26 screwed into the through hole 28. The push rod 22 is provided with a first thread part 221 which is matched with the second thread part 281 in a protruding mode along the radial direction; and the retainer ring 26 is stopped at the axial end surface of the first screw part 221. By adjusting the position of the stop ring 26, the maximum travel of the plunger 22 can be limited. A first reel 24 that is linked with the first rotor 23 is provided on one axial side of the first rotor 23, and a first driven wheel 25 that is linked with the first reel 24 in a wound manner is provided on the push rod 22. When the first wind wheel 23 is driven by wind, the push rod 22 moves towards the direction of pressing the trees when the first driven wheel 25 is driven.

The end of the push rod 22 is sleeved with a push head 224, the push head 224 is provided with a loading groove 226, and a notch of the loading groove 226 is provided with a blocking part 225. The end of the push rod 22 is provided with a head 222 slidably connected with the loading groove 226 and blocked by the blocking part 225, and a pre-pressure spring 223 is fixed between the end of the head 222 and the bottom of the loading groove 226. The end of the pushing head 224 away from the base frame 21 is curved, and a flexible pad 227 is disposed on the curved surface. After installation, the pusher head 224 abuts the outer surface of the tree and provides some pre-stress.

The reset mechanism 3 is a first torsion spring fixed between the base frame 21 and the push rod 22.

Referring to fig. 3, the foot rest 1 is fixed to a base frame 21 by means of bolt fastening, and the stabilizer bar 11, which is continuously bent in a corrugated shape, is fixed to the bottom of the foot rest 1 by means of bolts, and generally, after the installation, the stabilizer bar 11 is partially or entirely buried in the soil, and is fixed to the ground by means of additional ground nails 12, etc. to the foot rest 1.

The working mode is as follows:

in the normal state: the four pushing heads 224 are abutted against the four bearing surfaces of the tree, the pre-pressing spring 223 is pressed, the pushing heads 224 have certain pushing force on the tree, and the specific pushing force can be adjusted according to the variety and the growth condition of the tree.

When the wind power is high, the first wind wheel 23 is driven to move towards the tree through the transmission push rod 22 of the first winding wheel 24 and the first driven wheel 25 and further press the surface of the tree, so that the clamping effect on the tree is increased, and the clamping force is increased when the wind power is high; meanwhile, the first torsion spring is driven to accumulate elastic potential energy.

After the wind force is reduced, the elastic potential energy is released, the push rod 22 is gradually reversed and disengaged, the clamping force is reduced, the first driven wheel 25 is also rewound, and the wire is tightened.

Example 2: as shown in fig. 4 and 5, the difference from embodiment 1 is in the structure and the action of the return mechanism 3.

The reset mechanism 3 comprises a ratchet wheel 27 rotationally connected with the base frame 21 and a pawl 34 detachably connected with the base frame 21, wherein the push rod 22 is slidably arranged in the center of the ratchet wheel 27 and is in rotation stopping connection with the ratchet wheel 27; a return torsion spring is arranged between the ratchet wheel 27 and the base frame 21. (ii) a

The base frame 21 is provided with a mounting hole 345; the pawl 34 comprises a claw head 341 which is partially slidably arranged in the mounting hole 345, a suspension rod 342 which is threaded through the base frame 21, and a return spring 343 which urges the claw head 341 to be separated from the mounting hole 345; wherein, a sliding cavity 344 is arranged in the claw head 341, the end part of the suspension rod 342 is slidably arranged in the sliding cavity 344 and is provided with an anti-drop part for preventing the claw head 341 from dropping off the mounting hole 345, and the sliding direction of the claw head 341 is the radial direction of the ratchet wheel 27.

The working mode is as follows:

when driven by wind power, the push rod 22 moves and simultaneously drives the ratchet wheel 27 linked with the push rod to rotate, and the ratchet wheel 27 drives the reset torsion spring connected with the ratchet wheel 27 to store the force, but the elastic potential energy of the reset torsion spring cannot be released immediately due to the limitation of the pawl 34, namely the elastic potential energy is kept in a clamping state when the wind power is lower than a set threshold value; the push rod 22 will not be reset until the pawl 34 is removed. (ii) a The structure can be applied to some climatic regions with periodic strong wind to avoid the reaction speed of the mechanism being insufficient to deal with continuous and rapid change of the airflow, namely, the trees are reinforced at the beginning of the generation of the airflow, the wind resistance is improved, and the trees can be manually reset until the continuous change is finished.

Example 3: as shown in fig. 6-8, the difference from the embodiment 2 is that the structure of the second wind wheel 31 is added on the basis of the embodiment 2, which is different from the reset structure and the action mode.

A second driven wheel 33 is fixed at one end of the push rod 22 far away from the ratchet wheel 27, the second wind wheel 31 is arranged on the base frame 21, and a second reel 32 linked with the second wind wheel 31 is fixed at one axial side of the second wind wheel 31; the second driven pulley 33 is linked with the second reel 32 in a winding manner and drives the suspension rod 342 to move towards the ratchet wheel 27; the suspension lever 342 is provided with a second torsion spring between the base frames 21.

The working mode is as follows:

when the wind drives the push rod 22 and the ratchet wheel 27 to move in the same manner as the embodiment, at the same time, the second wind wheel 31 controls the second driven wheel 33 to drive the pawl 34 to move, so that the pawl is matched with the ratchet wheel 27.

When the wind power is reduced or eliminated, the suspension rod 342 starts to rotate reversely under the action of the second reset torsion spring, and the ratchet wheel 27 keeps in a power accumulation state due to the blocking of the pawl 34 in the process, and does not start to rotate reversely until the pawl 34 is disengaged; this provides a buffer space for the return of the plunger 22, i.e. the plunger 22 can be held in a constant compressed state when the wind fluctuates in size within a certain range.

When the wind direction changes, due to the existence of the buffering time, the first wind wheel 23 is not stressed and can be overturned rapidly enough to keep the tension state of the pull rope on the first wind wheel 23, at the moment, even if the pawl 34 is already loosened, the push rod 22 can still keep the pressing state, and in the process, the second wind wheel 31 also rotates reversely to continue to drive the pawl 34 to move to the state of abutting against the ratchet wheel 27.
