Description

Technical Field

[0001] This utility model relates to the field of fixing frame technology, and in particular to a retractable strawberry root zone nonwoven fabric positioning fixing frame. Background Technology

[0002] As a fruit with high economic value, strawberries require precise control of the rhizosphere environment (moisture retention, aeration, and pest control) in greenhouse cultivation to improve their quality.

[0003] However, existing cultivation racks have the following core defects, namely poor height adaptability: the traditional rack height is fixed and cannot match the changes in plant height from the seedling stage (low) to the fruiting stage (tall and robust) to the harvesting stage (operational height), resulting in insufficient root support, time-consuming bending during harvesting, or root damage caused by excessive height.

[0004] Lack of root zone fixation: Non-woven fabrics are mostly simply laid or tied, lacking the three-dimensional constraint of mechanical locking. The roots are prone to lateral scattering and longitudinal displacement, which damages the root zone moisture / breathing environment and increases the risk of soil-borne diseases (such as root rot) and lodging.

[0005] Low operational efficiency: Adjusting the height of the frame relies on cumbersome steps such as bolt disassembly and assembly, and rope binding, which has a high agronomic threshold and greatly increases labor costs when planting on a large scale; moreover, the locking structure has poor stability and is prone to shaking due to external forces (such as irrigation and wind), which further aggravates the disorder of the rhizosphere environment. Therefore, a telescopic strawberry rhizosphere non-woven fabric positioning and fixing frame is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a retractable strawberry rhizosphere nonwoven fabric positioning and fixing frame, which aims to improve the existing technology's inability to constrain the rhizosphere and thus achieve controllable rhizosphere environment throughout the entire growth period of strawberries, thereby reducing costs and improving efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 4 This utility model provides an embodiment of a retractable strawberry rhizosphere nonwoven fabric positioning and fixing frame, including a main rod 1, which serves as the core load-bearing structure of the device. A hollow cavity is formed inside the main rod 1. An inner rod 2 is slidably connected inside the main rod 1. The inner rod 2 is designed to adapt to the changing height of strawberry plants from short seedlings to tall and robust fruiting plants by "lifting / pressing down," with an adjustment range covering 10-30cm, achieving dynamic adaptation at different growth stages. An outer fixing sleeve 3 is fixedly connected to the outside of the main rod 1. 3 is designed to integrate the dispersed locking components into a mechanical system, enhancing structural compactness. The outer fixed sleeve 3 is externally rotatably connected to a rotating shaft 4. The rotating shaft 4 is designed with an elliptical cross section. When rotating, it uses the difference between the major and minor axes radii to generate radial compressive force. The rotating shaft 4 is elliptical in shape. The rotating shaft 4 is externally fixedly connected to a handle 5. The handle 5 is designed as the user's operating end. It drives the rotating shaft 4 to rotate through rotational torque, converting human power into mechanical locking power. The function of the handle 5 is to control the rotation of the rotating shaft 4.

[0033] Multiple sliding shafts 6 are internally slidably connected to the outer fixed sleeve 3. These sliding shafts 6 are designed to convert the "circumferential extrusion force" of the rotating shaft 4 into "linear thrust." One end of each sliding shaft 6 is fixedly connected to an extrusion column 7, which serves as a locking mechanism. A pressure block 8 is fixedly connected to the outside of the extrusion column 7, serving as the mechanical connection to achieve the "rotation → linear" motion. The pressure block 8 is externally slidably connected to the outside of the outer fixed sleeve 3. A pressure groove 9 is formed on the outside of the inner rod 2. 9 is a groove on the surface of the inner rod 2, which is adapted to the head contour of the extrusion column 7. The external part of the extrusion column 7 is engaged with the outside of the pressure groove 9. The main rod 1 is fixedly connected to the outside of the positioning hole 10. The positioning hole 10 is designed here to constrain the strawberry roots to grow downward. The function of the positioning hole 10 is to fix the strawberry roots. The inner rod 2 is fixedly connected to the outside of the positioning hole 11. The positioning hole 11 is designed here to construct the longitudinal constraint of "upper and lower anchoring". The function of the positioning hole 11 is to fix the strawberry roots.

[0034] Working Principle: The telescopic strawberry root zone non-woven fabric positioning and fixing frame achieves precise root fixation and growth adaptation through the synergistic logic of "mechanical linkage locking support + physical binding constraint of root position". The main rod 1 and the inner rod 2 form a telescopic system. The inner rod 2 can be manually lifted / pressed down, dynamically matching the height changes of strawberry plants from short seedlings to tall and robust fruiting plants, covering a range of 10-30cm. When the height is adjusted to the target position, turning the handle 5 drives the elliptical rotating shaft 4 to rotate. Its long axis squeezes the pressure block 8, pushing the sliding shaft 6 to drive the squeezing column 7 to retract radially, precisely engaging the pressure groove 9 of the inner rod 2. With the help of mechanical force, the main rod 1 and the inner rod 2 are rigidly locked, eliminating the risk of root zone displacement caused by support swaying. Meanwhile, the bottom positioning hole 10 of the main stem 1 and the top positioning hole 11 of the inner stem 2 form "upper and lower anchor points." By binding the non-woven fabric around the roots with cable ties, a three-dimensional constraint network of "longitudinal support + radial wrapping" is constructed: the lower end of the non-woven fabric is fixed by the positioning hole 10, restricting the roots from growing downwards; the upper end is lifted by the positioning hole 11, supporting the roots to extend upwards; the wrapping force of the non-woven fabric itself further constrains the lateral dispersion of the roots. Combined with the stable support height, the strawberry roots are firmly confined within the optimized rhizosphere space. This design, with "stretchable adaptation to the entire growth period, mechanical locking to ensure stability, and dual-hole binding to achieve three-dimensional constraint" as its core, lowers the agronomic threshold through simple operation of adjusting height → turning handle 5 → binding non-woven fabric, and strengthens the controllability of the rhizosphere environment in terms of moisture retention, air permeability, and pest prevention through a dual insurance mechanism of "mechanical locking + physical binding," laying a structural foundation for high-quality and high-yield strawberries.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
