Description

Tree planting survival cover

Technical Field

The utility model belongs to the technical field of the trees protection, especially, relate to a trees are planted into and are become living cover.

Background

In northern China, garden departments plant a large number of trees in spring every year, however, the survival rate is not high, and a plurality of key factors exist in rooting and survival: moisture, soil temperature, soil air permeability, tree shaking conditions, and winter protection of trees. The moisture can be solved by watering, but the soil temperature is only slowly raised by the natural temperature, the soil temperature is only a few degrees at the time of clearing the north generally, and is much lower than the temperature 15-25 degrees from rooting, the existing scheme uses plastic cloth to cover the root of a tree to play the roles of warming and moisturizing, but has three disadvantages, firstly, the wind in spring is heavy, dust flies, mud spots are fully distributed on the plastic cloth after raining, and the entering of illumination is greatly reduced; secondly, the plastic is tightly attached to the ground without a heat storage space, so that the heating effect is very limited; thirdly, the poured water cannot be dispersed, so that the air permeability of the soil is deteriorated. For the problem of tree shaking, the prior art uses a multi-purpose wooden pole to make a door-shaped frame, a tripod and a four-leg support for supporting, the supports are tightened and fixed by iron wires, the trees can be injured when the iron wires are tightened, the supports do not work when the iron wires are loosened, and the trees are often tightened or inclined. In winter, most of the cold protection adopts a method of whitewashing the trunk or winding the trunk with geotextile, the geotextile has deep color, can increase the absorption of light and is tightly attached to the trunk, so that the trunk can germinate too fast and early and is easily damaged by late spring cold. For this reason, a tree protection device capable of solving the above problems is demanded by the market.

Detailed Description

Referring to fig. 1 to 4, a tree planting living cover comprises a frame surrounding a trunk, a detachable tree fixer arranged at the top of the frame, and a protective layer covering the frame, wherein the frame is a quadrangular frustum pyramid with a square top and a square bottom, the whole frame is of a fully hollow structure, at least two fixing legs 1 with through holes are symmetrically fixed at the bottom of the frame, a connecting piece penetrates through the through holes to fix the frame on the ground, a rectangular gap penetrating from the top to the bottom is arranged on one side surface of the frame and serves as a tree inlet, one side of the tree inlet is hinged with a door 2 matched with the tree inlet, two horizontal limiting rods 3 are fixed on the top edge of the door 2, the two limiting rods 3 respectively grow out of the left side and the right side of the door 2, and when the door 2 is closed, the limiting rods 3 are fixed with top edges of the frame through twisted iron wires 4, a side nut 5 is respectively fixed on the top edge of the door 2 and three top edges of the frame without a tree inlet, four nuts 5 are respectively positioned at the middle part of each edge of the square at the top of the frame and are parallel to each edge, and four screw rods 6 matched with the nuts 5 are respectively screwed into each nut 5 towards the tree direction; the quantity of trees fixer is four, and trees fixer includes arc roof 7 and the sleeve pipe 8 of perpendicular fixation in arc roof 7 extrados center, lead screw 6 twists in the sleeve pipe 8 and make trees fixer laminate on the trunk.

In the embodiment, the frame can be formed by welding a plurality of steel bars, and the thickness of the steel bars and the size of the frame are adjusted according to the size of the tree. The connecting element passing through the through hole in the fixing foot 1 can be an earth anchor or an expansion bolt. The limiting rod 3 and the nut 5 can be fixed with the door 2 or the frame in a welding mode, and the arc-shaped top plate 7 and the sleeve 8 can be welded in the same way. The arc-shaped top plate 7 can be made of a steel plate.

Preferably, the frame is in the shape of a regular quadrangular frustum.

Preferably, four nuts 5 are located at the midpoint of each side of the square at the top of the frame to facilitate a tighter fit of the tree holder to the trunk.

Preferably, a vertical reinforcing bar 10 may be welded between the top and bottom edges of each side of the frame on three sides without the tree entrance, so that the structure is more stable, and the reinforcing bar 10 may be a reinforcing bar.

Preferably, the top edge of the door 2 is flush with the top edge of the frame, so that all four tree holders are at the same level, resulting in a more stable support effect.

Preferably, the inner arc surface of the arc-shaped top plate 7 is fixed with a rubber cushion layer 9, and the rubber cushion is soft and has the effect of not damaging trees.

In spring, the special plastic dripping film for the greenhouse is used as a protective layer, the soil temperature is quickly raised to the optimal rooting temperature, the moisture is prevented from being quickly dried by spring wind, the evaporated moisture flows to the four sides of the bottom of the frame along the inclined dripping film, and the soil ventilation property reaches the optimal semi-wet state.

In winter, the heat-insulating waterproof felt is used as a protective layer, so that the trees are not influenced by drought and cold.

The working principle of the scheme is as follows: the position of the frame is adjusted to enable the planted trees to enter from the tree inlet of the frame, and after the trees are positioned in the center of the frame, the fixing feet 1 at the bottom of the frame are firmly fixed on the ground by the ground anchors. The door 2 is closed and a wire 4 is threaded around the stop bar 3 of the door 2 and the top edge of the frame, securing them together, and then four lead screws 6 are threaded into four nuts 5, respectively, at the top of the frame. In the height range that flushes with screw 6, the manual arc roof 7 with the trees fixer withstands the trunk earlier, twists screw 6 again in the sleeve pipe 8 of trees fixer until screw 6 completely withstands the trees fixer on the trunk, has realized closely strutting the trees. And finally, covering a protective layer on the frame to play a role in sealing protection, taking the plastic dripping film as the protective layer in spring, clamping the dripping film on the edge of the frame by using a film pressing clamp, taking the heat-insulating waterproof felt as the protective layer in winter, compacting the bottom by using soil, and winding the top of the protective layer on the trunk by using an adhesive tape to enable the joint of the trunk and the protective layer to be in a sealed state.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and the present invention can be further modified with various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements should be included in the protection scope of the present invention.
