Description

Technical Field

[0001] The utility model relates to a shed, in particular to a pear tree shed structure. Background Art

[0002] Trellis cultivation can make use of the support of trellis materials to enhance the tree's load and wind resistance, greatly increase yield, increase fruit size and improve quality. At the same time, the tree height is moderate and there is space under the crown, which is convenient for agricultural operations such as spraying pesticides, thinning fruits, bagging and picking. It is also suitable for mechanized operations, thereby improving production efficiency.

[0003] However, at present, most pear tree trellises are horizontal, with complex shaping and pruning techniques, large amounts of labor, and late fruiting. All types of branches are laid horizontally on the trellis surface, and the main branches and extension branches often grow weakly, making it difficult to expand outward quickly, and the crown formation cycle is long.

[0004] Authorized Chinese patent CN 217012046 U discloses an improved V-shaped pear tree trellis, which includes several columns of support units, each column of support units includes several V-shaped frames arranged at intervals, and the ends of two adjacent V-shaped frames between columns are fixedly connected to form an arch-shaped structure; a first vertical steel pipe is fixed between the two arms of the V-shaped frame, and the lower end of the first vertical steel pipe extends out of the V-shaped frame and is pre-buried in the soil and cast with concrete to form a concrete mass. The trellis can reduce the height of the pear tree plant by setting a V-shaped frame, and can save a large number of bamboo poles, branch pullers and binding labor inputs used to fix the tree shape and open the base angle on the frame by pulling iron wire, thus saving labor costs; it overcomes the disadvantages of the labor-saving dense planting mode and the flat trellis, bears fruit in advance, and effectively improves the yield and quality of pears. It is a high-quality, efficient and labor-saving cultivation mode, which is conducive to the rapid realization of pear orchard standardization.

[0005] However, when the support rods are used as transverse supports to support the pear trees, a wire mesh is laid on the transverse supports. The wire mesh is prone to deformation during long-term use, resulting in changes in the support height, which is difficult to adjust. In addition, too many transverse supports are provided, which results in high costs. Utility Model Content

[0033] See also Figure 1-Figure 6 In an embodiment of the utility model, a pear tree trellis structure includes a plurality of columns of support units, each column of the support units is provided with a plurality of support frames;

[0034] In each column of support units, multiple support frames are arranged in a preset manner, and together they form a stable and compact support system. Each support frame is designed with a unique shape and size to meet the support requirements in different application scenarios. At the same time, the support frames are connected by detachable connectors, making the entire support system flexible and scalable.

[0035] In practical applications, the pear tree trellis structure can flexibly adjust the number and layout of the support units as needed to meet the requirements of different spaces and structures. In addition, the support frame can also be made of lightweight materials to reduce the overall weight and facilitate handling and installation.

[0036] Furthermore, the support frame body includes a vertical frame 1 and support frames 2 symmetrically arranged on both sides of the vertical frame 1, and a roller 4 is rotatably installed on the support frame 2, and a steel wire 3 arranged along the column direction passes through a through hole formed on the roller 4; the support frame body also includes an adjustment mechanism connected to the roller 4, and the adjustment mechanism is used to control the rotation of the roller 4 so that the number of turns of the steel wire 3 on the roller 4 increases or decreases.

[0037] The steel wire 3 is installed to support the branches of the pear tree. When the steel wire 3 is deformed or the tension needs to be adjusted, the roller 4 can be driven to rotate through the adjustment mechanism to adjust the length of the steel wire 3, thereby achieving adaptive adjustment to meet different support requirements and having a wide range of applications.

[0038] The bottom of the stand 1 is inserted into the ground and then a casting platform 101 is cast around it, thereby increasing the stability of the stand 1.

[0039] Among them, it should be noted that the steel wires 3 installed on the support frame 2 are distributed in columns, and the steel wires 3 distributed in columns and on the same horizontal plane can be installed with steel wires 3 horizontally. The specific installation method includes but is not limited to directly connecting two steel wires 3, so as to realize a support network with staggered distribution in columns and horizontally in the pear orchard.

[0040] Further, the support frame 2 is hinged on the stand 1 and connected to the stand 1 via an adjustable connector. Exemplarily, in a specific implementation, the adjustable connector includes:

[0041] A connecting frame 6, one end of which is hinged to the supporting frame 2, and the other end of which is hinged to a sliding sleeve 7 slidably disposed on the vertical frame 1;

[0042] A fixing piece is used to fix the sliding sleeve 7 to the stand 1.

[0043] The placement angle of the support frame 2 is adjusted by adjusting the installation position of the sliding sleeve 7 on the stand 1 in conjunction with the connecting frame 6. This flexible connection method allows the support frame to adapt to pear trees of different heights and provide stable support for the pear trees.

[0044] The fixing member includes a locking member 8 penetrating through the sliding sleeve 7, and a plurality of mounting holes 9 for the locking member 8 to pass through are formed on the stand 1. The locking member 8 includes but is not limited to a bolt and a nut matched with the bolt thread.

[0045] In this embodiment, the adjustment mechanism includes:

[0046] A connecting seat 15 located at one side of the supporting frame 2 and fixedly connected to the roller 4, wherein an embedded groove 1501 is formed on the connecting seat 15 along the axial direction;

[0047] A movable column 11 that penetrates the support frame 2 and extends into the embedded groove 1501, wherein the movable column 11 is slidably connected to the connecting seat 15 and is connected to an elastic member disposed in the embedded groove 1501. Preferably, the elastic member comprises a spring 13, wherein one end of the spring 13 abuts against an end of the embedded groove 1501, and the other end abuts against an extension member formed on the movable column 11;

The side of the ring member 14 facing the knob 5 is provided with a locking groove 1401 adapted to the locking teeth 10.

[0049] When the latch tooth 10 is inserted into the latch slot 1401, the position of the movable column 11 is fixed, and the roller 4 cannot rotate either. At this time, the steel wire 3 is in a fixed state. When the tightness (release length) of the steel wire 3 needs to be adjusted, the knob 5 is manually pulled to disengage the latch tooth 10 from the latch slot 1401, and then the knob 5 is turned. When the knob 5 is turned, the movable column 11 is driven to rotate synchronously, so that the roller 4 rotates, thereby winding or unwinding the steel wire 3 to achieve the adjustment requirements.

[0050] Preferably, a limiting slider 12 is also provided on the side wall of the movable column 11, and a limiting slide groove 1502 is formed on the side wall of the embedded groove 1501, which slides with the limiting slider 12, so that the movable column 11 can move axially along the connecting seat 15, and when the movable column 11 rotates radially, it can drive the connecting seat 15 to rotate synchronously.
