Description

Technical Field

[0001] The utility model relates to the technical field of agricultural facilities, and particularly relates to a seedling-raising bed arch shed device. Background Art

[0002] During seedling raising, in some special periods of seedlings (such as before and after grafting), it is necessary to shade or keep warm and moisturize the local environment of the seedlings to form a microenvironment conducive to the growth of the seedlings. Intensive seedling raising mostly uses special seedling-raising beds. In the prior art, small arch sheds are often built on the seedling-raising beds. Generally, bamboo poles or flexible plastic rods are bent and then tied to the side walls of the seedling-raising beds, and then a thin film is covered on them to form a small arch shed. The installation and removal processes are time-consuming and laborious, and not firm. There are also cases where the support rods are fixed to the side walls of the seedling-raising beds during installation, and only the covering film is removed during removal, eliminating the disassembly man-hours. However, the support rods fixed to the seedling-raising beds affect other operations. There is also a clamping type bracket, that is, both ends of the bracket have fixed clips. When in use, the fixed clips are clamped on both sides of the seedling-raising bed. The fixed clip structure fittings are relatively complex and the cost is relatively high.

[0022] The technical solutions of the present 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 the present utility model, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 , in agricultural production, the seedling-raising stage is crucial for the healthy growth of crops. In order to improve the seedling-raising efficiency and ensure that the seedlings grow vigorously in a suitable environment, an efficient and convenient seedling-raising bed arch shed device is provided. The following will elaborate on the specific implementation manners of the device in detail, including material selection, structural assembly, usage steps and optimization measures.

[0024] I. Material Selection and Preparation

[0025] 1. Fixed Unit Materials (Refer to Figure 2 )

[0026] For the side plate 11, corrosion-resistant and high-strength PVC plates or galvanized iron sheets are selected as the side plate materials. These materials are not only light and easy to process, but also can effectively resist the erosion of the external environment and extend the service life. The thickness of the side plate is recommended to be 2 - 3 mm, and the width is customized according to the actual size of the seedling bed to ensure that it can be firmly clamped on the side plate of the seedling bed.

[0027] For the top plate 12, the top plate also uses PVC plates or galvanized iron sheets. However, considering that holes need to be drilled for installing the brackets, its thickness should be slightly greater than that of the side plate, and it is recommended to be 3 - 4 mm. The top plate needs to be flat and free of deformation to ensure stability after the brackets are inserted.

[0028] Refer to Figures 3 - 4 , the reinforcement 14 is used to enhance the stability of the fixed unit. Materials of the same or similar material as the side plate can be selected. Its shape should match the fixed unit, be easy to install and not affect the overall aesthetics. The length and width of the reinforcement are designed according to actual needs to ensure that the fixed unit can be effectively reinforced.

[0029] 2. Bracket Materials

[0030] The bracket 2 is a key component for forming the arch shed structure. Materials that are easy to bend but still have strength should be selected. Common choices include natural materials such as plastic elastic rods, bamboo poles, fruit tree branches, as well as special metal or plastic pipes. These materials are low-cost, easy to obtain, and can meet the usage requirements in different environments. The diameter and wall thickness of the bracket need to be determined according to the size of the socket 13 to ensure that it can maintain stability after insertion without being too tight and damaging the socket.

[0031] Refer to Figure 5 , the L-shaped bracket 21, as another form of bracket, the L-shaped bracket has higher structural strength and stability. Its material can also be selected from plastics, metals, etc. The height is designed to be 20 - 40 cm to meet the growth requirements of different crops. The right-angled part of the L-shaped bracket is used to insert into the socket of the top plate, and the horizontal part is used to support the covering film and other additional equipment.

[0032] 3. Covering Film Materials

[0033] The covering film 3 is an important part of the arch shed device and is used to adjust the temperature, humidity and light conditions inside the shed. According to the seedling raising requirements, polyethylene films, EVA films or special seedling raising films with good light transmittance can be selected. These materials not only have good heat preservation and moisture retention properties, but also can effectively prevent the invasion of pests and diseases. The thickness and width of the covering film need to be determined according to the actual size and use of the arch shed.

[0034] II. Structural Assembly

[0035] 1. Assembly of the Fixing Unit

[0036] First, cut the PVC board or galvanized iron sheet into the required side plates and top plates according to the size of the seedling bed. Subsequently, evenly drill a plurality of jacks 13 on the top plate. The diameter of the jacks should be slightly larger than the outer diameter of the brackets to ensure that the brackets can move stably and smoothly after being inserted.

[0037] Place the two side plates 11 parallel to each other and connect them with the top plate 12 at the top to form a U-shaped structure. Ensure that the connection between the side plate 11 and the top plate 12 is tight without any gaps or looseness. The notch of the U-shaped structure should face downward for subsequent clamping on the top of the seedling bed.

[0038] Refer to Figure 3 , and install the reinforcement member 14 at the end of the fixing unit 1 or at the position where enhanced stability is required. The reinforcement member 14 should be firmly clamped outside the side plate 11 to form a stable support structure with the side plate 11.

[0039] 2. Installation of the Brackets

[0040] For the easily bendable rod-shaped brackets 2, bend the brackets into an appropriate arc according to the width of the seedling bed and the height of the required arch shed. Ensure that both ends of the bracket 2 can be smoothly inserted into the jacks on the top plate of the fixing unit 1.

[0041] Insert both ends of the bracket 2 into the jacks 13 on the top plate 12 of the fixing units 1 on both sides of the seedling bed respectively. When inserting, pay attention to maintaining the verticality and stability of the bracket to avoid tilting or shaking.

[0042] After inserting the bracket 2, adjust the position and angle of the bracket 2 as needed to ensure the flatness and stability of the arch shed structure. If necessary, use ropes or clips to assist in fixing the bracket.

[0043] 3. Laying of the Covering Film

[0044] Unroll the selected covering film 3 above the arch shed to ensure that the area of the covering film is sufficient to cover the entire arch shed structure.

[0045] Use ropes, clips or special fixing devices to fix the covering film on the brackets 2 and the fixing unit 1. When fixing, pay attention to keeping the covering film flat and taut to avoid wrinkles or sagging.

[0046] Carefully check and adjust the edges and joints of the covering film 3 to ensure there is no air or rain leakage. If necessary, use tape or sealant for sealing.

[0047] III. Usage Steps

[0048] Prepare the seedling-raising bed: First, clean the surface debris and residues of the seedling-raising bed to ensure that the bed surface is flat without bumps or depressions. Adjust the soil moisture and nutrient content of the seedling-raising bed according to the crop variety and growth requirements.

[0049] Install the fixing unit: Insert the assembled U-shaped fixing unit with the notch facing down into the side plates of the seedling-raising bed. Ensure that there is a tight fit without gaps between the side plates and the side plates of the seedling-raising bed. Install reinforcement parts as needed to enhance the stability.

[0050] Install the brackets: Select appropriate bracket materials according to the width of the seedling-raising bed and the height of the required arch shed, and bend them into an appropriate arc. Insert the two ends of the brackets into the jacks on the top plate of the fixing unit respectively and adjust them to the appropriate positions.

[0051] Lay the covering film: Unfold the covering film above the arch shed and use fixing devices to fix it on the brackets and the fixing unit. Ensure that the covering film is flat without wrinkles and is well-sealed.

[0052] Management and maintenance: Regularly check the stability of the arch shed structure and the integrity of the covering film during use. Clean the accumulated water and debris on the covering film in time to maintain good light transmittance and air permeability. Adjust the temperature, humidity, and light conditions in the shed in a timely manner according to the crop growth requirements.

[0053] IV. Optimization measures

[0054] Enhance stability: Add reinforcement ribs or stiffeners outside the side plates of the fixing unit to improve its wind resistance and load-bearing capacity. At the same time, an appropriate amount of lubricant can be applied between the brackets and the jacks to reduce the frictional resistance and extend the service life.

[0055] Improve light transmittance: Select covering film materials with better light transmittance, such as EVA film or special seedling-raising film, to increase the light intensity in the shed. Regularly clean and maintain the covering film to keep its good light transmission performance.

[0056] Regulate temperature and humidity: Install temperature and humidity monitoring equipment inside the arch shed to monitor the environmental parameters in the shed in real time. Adjust the size of the ventilation openings, the number of water sprayings, and the degree of shading net coverage in a timely manner according to the monitoring results to maintain appropriate temperature and humidity conditions.

[0057] Optimize the structural design: Optimize the structure of the arch shed device according to different crop varieties and growth requirements. For example, for tall crops, the height and span of the brackets can be appropriately increased to provide more sufficient growth space; for low-growing crops, the bracket height can be appropriately reduced to reduce material waste and improve stability.

[0058] In summary, this seedling-raising bed arch shed device has the advantages of simple structure, convenient assembly, low cost, and wide application range. Through reasonable material selection and structural optimization design, it can meet the seedling-raising requirements under different crop varieties and growth needs.
