Description

Technical Field

[0001] This utility model relates to a natural supplemental lighting device for intercropping in orchards. Background Technology

[0002] Intercropping in orchards is a common agricultural production model that achieves multiple harvests from a single plot of land by planting different crops under fruit trees. Intercropping not only improves the ecological environment of orchards, enhances soil and water conservation, and optimizes the orchard ecosystem, but also increases land utilization, promotes fruit quality improvement, and increases farmers' income. Southern my country experiences heavy and concentrated rainfall, which can negatively impact fruit setting and centralized management of some fruit trees. Therefore, greenhouse cultivation is being widely promoted in the south. Developing greenhouse fruit tree cultivation is an important means of building resource-saving and environmentally friendly agriculture. It can increase arable land use, reduce water resources, chemical pesticides, and energy consumption per unit of output, comprehensively improving agricultural production efficiency and achieving environmentally friendly and resource-saving agricultural production. It also fully utilizes the natural environment and plant potential, possessing high market competitiveness and the ability to withstand market risks. It is a high-profit industry in planting and a new industry in rural economic development, as well as another channel for farmers to continuously increase their income.

[0003] To make full use of land area, growers often intercrop other crops under fruit trees. This intercropping pattern may result in insufficient light for the lower layers, affecting the growth of these crops. Artificial supplemental lighting is costly and inefficient, and its spectral range is not as wide as natural light, nor does it offer the same stability as sunlight-driven growth. Therefore, a more comprehensive system of natural supplemental lighting is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a natural supplementary lighting device for intercropping in orchards, which is not only reasonably structured, but also can be used for a long time and reduces the cost of supplementary lighting.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a natural supplementary lighting device for intercropping in orchards, including a support pipe vertically mounted on a trellis of a planting shed, a light-collecting cover at the top of the support pipe, a telescopic pipe vertically telescopically connected inside the support pipe, a number of guide rods hinged at intervals along the outer periphery of the bottom of the telescopic pipe, and a supplementary lighting cover at the outer end of each guide rod, with optical fiber guiding light inside the light-collecting cover, the optical fiber extending inside the support pipe and the telescopic pipe and passing through the telescopic pipe to connect with the supplementary lighting cover.

[0006] Furthermore, the telescopic tube has several strip-shaped holes near its bottom for optical fibers to pass through.

[0007] Furthermore, both the telescopic tube and the support tube have square cross-sections, and the telescopic tube has protruding clamps on all four sides for clamping the guide rod after flipping.

[0008] Furthermore, the clamping device includes two parallel elastic clamping rods, and the outer ends of the two elastic clamping rods are fixed with anti-detachment clamping heads in the shape of right-angled trapezoids.

[0009] Furthermore, the support tube is fixedly provided with clamps that correspond one-to-one with the guide rods along its outer perimeter.

[0010] Furthermore, a connecting plate is fixedly provided near the top of the support tube along its outer periphery and is connected to the rattan frame via the connecting plate.

[0011] Furthermore, the telescopic tube is infinitely telescopically adjustable within the support tube or is limited by sliding engagement with an adjusting component. The adjusting component includes a spring seat fixed to the outer wall of the telescopic tube, on which a protrusion is connected by a spring. The support tube is provided with a plurality of adjustment holes spaced apart along its vertical extension direction for the protrusion to be pushed out and limited. The inner end of the protrusion is fixed with a flange along its periphery to prevent it from falling out of the adjustment hole.

Detailed Implementation

[0020] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0021] like Figures 1-5 As shown, a natural supplemental lighting device for intercropping in orchards includes a support pipe 3 vertically mounted on a trellis 2 of a planting shed 1. A light-collecting cover 4 is provided at the top of the support pipe. A telescopic pipe 5 is vertically adjustable inside the support pipe. Several guide rods 6 are hinged at intervals along the outer periphery of the bottom of the telescopic pipe. A supplemental lighting cover 7 is provided at the outer end of each guide rod. Light is guided by an optical fiber 8 inside the light-collecting cover. The optical fiber extends inside the support pipe and the telescopic pipe and passes through the telescopic pipe to connect with the supplemental lighting cover. The optical fiber has sufficient extension length space in the support pipe and the telescopic pipe.

[0022] In this embodiment of the utility model, an optical fiber receiver 9 is provided inside the light-collecting cover. The top of the optical fiber is connected to the optical fiber receiver to guide high-intensity sunlight into the optical fiber. The high-intensity sunlight is transmitted through the flexible transmission of the optical fiber to the supplementary light cover inside the planting greenhouse. The supplementary light cover disperses the sunlight to provide supplementary lighting for the crops at the bottom of the planting greenhouse. An optical fiber splitter is required at the connection point to directly emit the sunlight. This is a common setting and will not be described in detail here.

[0023] In this embodiment of the utility model, the telescopic tube has several strip-shaped holes 10 near its bottom for optical fibers to pass through.

[0024] In this embodiment of the utility model, both the telescopic tube and the support tube have square cross-sections, and clamping devices 11 protrude from all four sides of the telescopic tube to clamp the guide rod after flipping.

[0025] In this embodiment of the utility model, the clamping device includes two parallel elastic clamping rods 12, and the outer ends of the two elastic clamping rods are fixed with anti-detachment clamping heads 13 in the shape of right-angled trapezoids. The elastic clamping rods and the anti-detachment clamping heads are fixedly connected as one unit.

[0026] In this embodiment of the utility model, the support tube is fixedly provided with clamps that correspond one-to-one with the guide rods along its outer perimeter.

[0027] In this embodiment of the utility model, the guide rod and the hinge seat 13 fixed on the telescopic tube are connected by a high-damping rotational connection so as to adjust the unfolding angle. Each hinge seat is fixed with a horizontally extending limiting plate 14 to prevent the guide rod from swinging down excessively.

[0028] In this embodiment of the utility model, a connecting plate 15 is fixedly provided near the top of the support tube along its outer periphery and is connected to the rattan frame via the connecting plate.

[0029] In this embodiment of the utility model, the telescopic tube is infinitely telescopically adjustable within the support tube or is limited by sliding engagement with an adjusting member. The adjusting member includes a spring seat 16 fixed to the outer wall of the telescopic tube. A protrusion 18 is connected to the spring seat via a spring 17. The support tube is provided with a plurality of adjustment holes 19 spaced apart along its vertical extension direction for the protrusions to be pushed out and limited. A flange 20 is fixedly provided at the inner end of the protrusion along its periphery to prevent it from falling out of the adjustment hole.

[0030] The working principle of this utility model embodiment is as follows: light is collected through a light-collecting cover that extends above the trellis, and then high-intensity sunlight is guided into the optical fiber through an optical fiber receiver. The high-intensity sunlight is transmitted through the flexible transmission of the optical fiber to the supplementary light cover inside the planting greenhouse. The supplementary light cover then disperses the sunlight to provide supplementary lighting for the crops at the bottom of the planting greenhouse.

[0031] This utility model is not limited to the preferred embodiment described above. Anyone can derive other forms of natural supplemental lighting devices for orchard intercropping based on the inspiration of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model shall fall within the scope of this utility model.
