Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically an adjustable sunshade device for agricultural planting. Background Technology

[0002] Planting refers to agricultural activities involving the cultivation of plants through artificial breeding, encompassing categories such as crops, forest trees, fruit trees, flowers, medicinal plants, and ornamental plants. Traditional planting is land-based, including tillage, seedling cultivation, and field management, and is subject to farmland protection policies, requiring a balance between food security and sustainable production. Plants need sufficient sunlight to grow and achieve photosynthesis; however, in drought conditions and exceptionally high temperatures, excessive sunlight can cause sunburn.

[0003] Chinese utility model patent CN223080667U, published on July 11, 2025, discloses a sunshade for agricultural planting, including a top frame. A top shading mechanism is installed at the top of the top frame, and a side shading mechanism is installed around the top frame. The top shading mechanism includes a guide rail installed in the middle of the top frame, a screw installed in the middle of the guide rail, a slider installed on the screw, and a second motor installed on the outer wall of the top frame opposite the screw. The advantages are: firstly, this utility model allows for flexible adjustment of the top shading area through the action of the second motor, screw, slider, guide rail, pull bar, first motor, and roller in the top shading mechanism; secondly, it allows for flexible adjustment of the side shading area through the action of the first and second electric winding boxes and the counterweight in the side shading mechanism. This meets the flexible shading and sunlight exposure needs of crops during summer cultivation, making the sunshade more flexible in use.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: Existing shading devices use horizontally set shading nets to block the angle of sunlight at the time of day when the sunlight intensity is the highest, thereby achieving maximum sunlight isolation and preserving normal sunlight intensity. However, they cannot adjust the light transmittance and shading area, and therefore cannot meet precise lighting requirements. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of existing shading devices, which use horizontally set shading nets to block the angle of sunlight at the time of day with the strongest sunlight, thereby achieving the goal of blocking the maximum sunlight and preserving normal sunlight intensity, but cannot adjust the light transmittance and shading area, thus failing to meet the technical requirements of precise lighting. The invention provides an adjustable shading device for agricultural planting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses an adjustable sunshade device for agricultural planting, comprising a central ring made of bent metal; multiple unit plates are slidably sleeved on the central ring with gaps; a support shaft is detachably fixed to the lower end of each unit plate; a horizontal shaft is fixed to the lower end of the support shaft; a positioning pin is sleeved on the horizontal shaft; and a sunshade component is sleeved on the outer surface of the support shaft.

[0008] Furthermore, inlet and outlet slots are formed at both ends of the central ring; the width of the inlet and outlet slots is greater than or equal to the thickness of the unit plate.

[0009] Furthermore, the lower end opening of the unit plate is threadedly connected to the upper end of the support shaft.

[0010] The adjustable shading device for agricultural planting provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses a hammer to drive the positioning pins into the soil, thereby fixing the positioning pins in the soil. When multiple positioning pins are located at the four corners of the planting field, the unit plates at the upper ends of the four support shafts are slidably connected to the central ring, thereby forming a fixed shape of a quadrangular truncated pyramid. Then, multiple layers of shading components are wrapped around the outer surface of the four support shafts to achieve shading treatment for the planting field below. At the same time, the shading components form a quadrangular truncated pyramid shape, so that both the upper and lower ends are open, and air and water vapor can flow freely and be carried away, so that the light, water, temperature and air required for plant growth can be met at the same time.

[0012] 2. This utility model uses a bending process to form a central ring, and with the avoidance of the inlet and outlet grooves, it allows for the installation and disassembly of unit plates, thereby achieving the connection and fixation of multiple support shafts with the ground soil, resulting in higher connection strength and the ability to resist greater wind forces.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, an adjustable shading device for agricultural planting includes a central ring 1 made of bent metal; multiple unit plates 3 are slidably sleeved on the central ring 1; a support shaft 4 is detachably fixed to the lower end of the unit plate 3; a horizontal shaft 5 is fixed to the lower end of the support shaft 4; a positioning pin 6 is sleeved on the horizontal shaft 5; and a shading element 9 is sleeved on the outer surface of the support shaft 4. The positioning pin 6 is hammered into the soil by a hammer, thereby fixing the positioning pin 6 in the soil. When multiple positioning pins 6 are located at the four corners of the planting field, the unit plates 3 at the upper ends of the four support shafts 4 are slidably connected to the central ring 1, thereby forming a fixed shape of a quadrangular truncated pyramid. Then, multiple layers of shading elements 9 are wrapped around the outer surface of the four support shafts 4 to achieve shading treatment for the planting field below. At the same time, the shading elements 9 form a quadrangular truncated pyramid shape, so that both the upper and lower ends are open, and air and water vapor can flow freely and be carried away, so that the light, water, temperature and air required for plant growth can be met at the same time.

[0022] The two ends of the central ring 1 form inlet and outlet grooves 2; the width of the inlet and outlet grooves 2 is greater than or equal to the thickness of the unit plate 3, so that the central ring 1 can be processed by bending, and the unit plate 3 can be installed and disassembled under the avoidance of the inlet and outlet grooves 2, thereby realizing the connection and fixation of multiple support shafts 4 with the ground soil, so that the connection strength is higher and it can resist the wind force of a higher level.

[0023] The lower end of the unit plate 3 is threaded to the upper end of the support shaft 4. The unit plate 3 and the support shaft 4 are connected by a threaded connection, which makes it easy to install and disassemble. It can be used in combination as needed and has high replaceability. If a single support shaft 4 is damaged, it can be disassembled and replaced with a new support shaft 4.

[0024] An adjusting ring 7 is slidably sleeved on the outer surface of the support shaft 4; a fastener 8 is threadedly connected to the outer surface of the adjusting ring 7 through an opening; the fastener 8 changes the friction between the adjusting ring 7 and the outer surface of the support shaft 4 by rotating, so that the friction between the adjusting ring 7 and the outer surface of the support shaft 4 can be controlled by rotating forward and backward, thereby adjusting the position of the adjusting ring 7 on the outer surface of the support shaft 4, thus being compatible with different sunshade films and different heights of sunshade effect.

[0025] The central ring 1, unit plate 3, support shaft 4, horizontal shaft 5, positioning pin 6, adjusting ring 7, and fasteners 8 are made of rust-resistant metal, which ensures that they maintain their shape stability during long-term outdoor use, can withstand normal use under certain wind levels, and resist the impact of large-area rain on plants.

[0026] The shading component 9 is a continuous multi-layer wound film shape. By continuously winding the film into multiple layers, the shading component 9 can be made with low requirements for the width and length of the shading film, and is compatible with all shading films. At the same time, it can be adapted to support shafts 4 at different angles, so that the shading area can be adjusted to suit different planting field shapes, so that the shading effect can be achieved, and it can be reused.
