Description

Technical Field

[0001] This utility model belongs to the field of konjac planting technology, specifically relating to a special shading device for konjac planting. Background Technology

[0002] Konjac is a semi-shade plant, and some shading measures are needed when planting it to prevent sunlight from shining directly on it. In modern facility agriculture cultivation, konjac is generally covered with shade netting.

[0003] Shade nets are beneficial for providing shade over large areas, but most current shade frames adopt a modular assembly structure. When setting up a shade frame, operators need to be directly involved in the manual assembly and adjustment of the shade frame. The assembly and disassembly process is time-consuming and labor-intensive, with poor ease of assembly and high labor intensity. In addition, the disassembly and assembly process is also quite troublesome. Furthermore, the shade height and coverage area cannot be adjusted according to the size and area of ​​the plant, making it not very practical. Utility Model Content

[0004] To overcome the problems of current konjac shade nets, which mostly use a modular assembly structure, resulting in high labor intensity and cumbersome assembly and disassembly, and are not practical as they cannot adjust the shading height and coverage area according to plant size and area, this utility model provides a special shading device for konjac cultivation. The device adjusts the position of the lifting rod inside the column and is fixed by a limiting column, thereby changing the overall height of the arched support structure and achieving height adjustment of the shade net. The telescopic component is hinged between adjacent lifting rods, allowing simultaneous adjustment of the spacing between multiple lifting rods. As the spacing of the lifting rods changes, the width of the arched support structure formed by the arc-shaped support rods also changes, thus flexibly changing the coverage area of ​​the shade net. The shade net provides a suitable shading environment for konjac, avoiding the adverse effects of direct sunlight on its growth and promoting healthy growth.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A special shading device for konjac cultivation mainly includes a fixed base, a column, a lifting rod, a limiting column, an arc-shaped support rod, a telescopic component, and a shading net. The column is installed on the top of the fixed base, and the inside of the column is set as a hollow structure. The lifting rod is slidably installed inside the column. Multiple limiting holes are opened axially on the column and the lifting rod. The limiting column, used to lock the height position of the lifting rod, passes through the column and the lifting rod and is installed in the limiting holes to connect the column and the lifting rod. The arc-shaped support rod is horizontally connected to the top of the two lifting rods to form an arched support structure. The telescopic component, used to synchronously adjust the spacing of multiple sets of lifting rods, is hinged between adjacent lifting rods. The shading net is laid on the top of the arc-shaped support rod.

[0006] The telescopic assembly includes a first link, a second link, and a fastening bolt. The side wall of the lifting rod has an elongated groove along the axial direction. The top ends of the first link and the second link are respectively connected to the upper part of the adjacent lifting rod through a hinge shaft, and the bottom ends are slidably installed in the groove of the adjacent lifting rod. The fastening bolt passes through the staggered connection point in the middle of the first link and the second link to lock the relative angle of the two links.

[0007] The base is provided with a fixing hole at the bottom, in which ground nails or expansion bolts can be detachably installed.

[0008] The shade net has nylon straps along its edges.

[0009] The beneficial effects of this utility model are:

[0010] In konjac cultivation, the size of the plant varies at different growth stages, and the requirements for shading area and height also differ. Adjusting the position of the lifting rod inside the column and fixing it with the limiting column changes the overall height of the arched support structure, thereby adjusting the height of the shade net. The telescopic component is hinged between adjacent lifting rods, allowing for simultaneous adjustment of the spacing between multiple sets of lifting rods. As the spacing between the lifting rods changes, the width of the arched support structure formed by the arc-shaped support rods also changes, thus flexibly changing the coverage area of ​​the shade net. The shade net provides a suitable shading environment for konjac, avoiding the adverse effects of direct sunlight on its growth and promoting its healthy development. Attached Figure Description

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] This utility model discloses a special shading device for konjac cultivation. The special shading device for konjac cultivation mainly includes: 1. a fixed base 1, a column 2, a lifting rod 3, a limiting column 4, an arc-shaped support rod 5, a telescopic component 6, and a shading net 7. The column 2 is installed on the top of the fixed base 1. The inside of the column 2 is set as a cavity structure. The lifting rod 3 is slidably installed inside the column 2. Multiple limiting holes 21 are opened axially at intervals on the column 2 and the lifting rod 3. The limiting column 4, which is used to lock the height position of the lifting rod 3, passes through the column 2 and the lifting rod 3 and is installed in the limiting holes 21 to connect the column 2 and the lifting rod 3. The arc-shaped support rod 5 is horizontally connected to the top of the two lifting rods 3 to form an arched support structure. The telescopic component 6, which is used to synchronously adjust the spacing of multiple sets of lifting rods 3, is hinged between adjacent lifting rods 3. The shading net 7 is laid on the top of the arc-shaped support rod 5.

[0018] The telescopic component 6 includes a first connecting rod 61, a second connecting rod 62, and a fastening bolt 63. The side wall of the lifting rod 3 has an axially oriented elongated groove 31. The top ends of the first connecting rod 61 and the second connecting rod 62 are respectively connected to the upper part of the adjacent lifting rod 3 via hinge shafts, and the bottom ends are slidably installed in the groove 31 of the adjacent lifting rod 3. The fastening bolt 63 passes through the staggered connection point in the middle of the first connecting rod 61 and the second connecting rod 62 to lock the relative angle of the two connecting rods. The telescopic component 6 is hinged between adjacent lifting rods 3, which can simultaneously adjust the spacing of multiple sets of lifting rods 3. As the spacing of the lifting rods 3 changes, the width of the arched support structure formed by the arc-shaped support rod 5 also changes, thereby flexibly changing the coverage area of ​​the shade net 7.

[0019] The fixing base 1 has a fixing hole 11 at the bottom, in which ground nails or expansion bolts can be detachably installed; so that the fixing base 1 is firmly fixed to the ground and the stability of the entire shading device is guaranteed.

[0020] The shade net 7 is provided with nylon straps at its edges; the nylon straps ensure that the shade net is not easily moved or blown away by natural wind or other external factors, thus ensuring the continuity of the shading effect.

[0021] Work process:

[0022] First, determine the location in the konjac planting area where the shading device needs to be installed. Place the fixing base 1 and the column 2 in the selected location. Then, based on the initial approximate height requirement of the konjac plant, initially set the position of the lifting rod 3. Observe the multiple limiting holes 21 spaced along the axial direction on the column 2 and the lifting rod 3. Pass the limiting post 4 through the corresponding limiting holes 21 on the column 2 and the lifting rod 3 to determine the height position of the lifting rod 3 within the column 2. This achieves the initial adjustment of the shading height based on the current height of the konjac plant. After the height adjustment is completed, if it is necessary to adjust the coverage area of ​​the shading device to adapt to changes in the planting area of ​​the konjac plant, first loosen the fastening bolt 63. This operation allows the first connecting rod 61 and the second connecting rod 62 to move freely. Then push the adjacent lifting rod 3. During the operation, the hinge shafts at the top of the first connecting rod 61 and the second connecting rod 62 remain stationary, while the bottom ends of the first connecting rod 61 and the second connecting rod 62 slide along the sliding groove 31, thereby driving the lifting rod 3 to move synchronously and change the spacing. When a suitable coverage area is achieved, it can completely cover the required area. After shading the konjac planting area, tighten the fastening bolts 63 to lock the relative angle of the first connecting rod 61 and the second connecting rod 62. Then, depending on the soil conditions, select ground nails or expansion bolts to firmly fix the fixing base 1 to the ground. After all the sets of lifting rods 3 are installed and positioned at the correct height, take the arc-shaped support rod 5 and connect it laterally to the top of the two lifting rods 3 to form an arched support structure. This arched structure can better adapt to the shape of the konjac planting area and provide stable support for the shade net 7, ensuring that the shade net 7 can provide shade. To effectively block sunlight and meet the growth requirements of konjac semi-shade plants, take out the shade net 7 and lay it flat on the top surface of the arch formed by the arc-shaped support rod 5. When laying it, ensure that the shade net 7 completely covers the top of the arch support structure to provide the konjac with the maximum shade effect. Use the nylon straps set on the edge of the shade net 7 to firmly tie the shade net 7 to the arc-shaped support rod 5 to ensure that the shade net 7 will not easily move or be blown away no matter if it is exposed to natural wind or other external factors, thus ensuring the continuity of the shading effect.

[0023] When the konjac needs to adjust the shading height at different growth stages, pull out the limiting post 4 to release the lock between the upright post 2 and the lifting rod 3. Slide the lifting rod 3 up and down along the cavity of the upright post 2 to the new height, align it with the limiting hole 21, and then reinsert the limiting post 4. If it is necessary to adjust the shading area, remove the ground nails or expansion bolts, loosen the fastening bolts 63 of the telescopic component 6, so that the first connecting rod 61 and the second connecting rod 62 can slide freely in the sliding groove 31, pushing the adjacent lifting rod 3 to expand outward or retract inward to complete the adjustment of the shading area. After the adjustment is completed, install the fixing seat 1 in the field through the ground nails or expansion bolts.

[0024] When dismantling during the harvest season, remove the nylon straps to retrieve the shade net 7, pull out the limit post 4 to store the lifting rod 3 inside the column 2, and remove the ground nails or bolts of the fixing seat 1. The entire device can be folded for storage, reducing the floor space by 70%. Lubricant is injected into the slide 31 every quarter, and the integrity of the anti-rust coating on the fastening bolts 63 is checked. The shade net 7 can be replaced individually without the need for complete dismantling.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
