In the growth process of crops, sunlight and rain are the key factors affecting yield and taste. If the sunlight is too strong, it will burn the seedlings, and too much water will easily cause root rot. Therefore, for crops, the most important thing to contact and adapt to the natural environment is to allow crops to receive appropriate amounts of sunlight and rain. Therefore, shading and sheltering from rain are very important for the healthy growth of seedlings. Existing sunshades or rain shelters usually use high-strength fixed shed films, or hinged arm shed films. This structure is relatively complex, not only the cost is very high, but also the shed film cannot be flexibly retracted for replacement. Usually, only one kind of rain-proof film or sun-proof film can be fixedly installed, with a single function, and it is necessary to use ladders and other auxiliary tools to install and remove the rain-proof film or sun-proof film.

[0003] For a long time, crops in my country have generally been planted on land in the fields. Due to the long-term continuous cropping obstacles and the degradation of varieties, the yield and quality of crops will be reduced.

[0036] like Figure 1 As shown, the utility model provides an elevated planting structure, comprising:

[0037] An elevated planting structure includes a protective shed 100 and a planting device located under the protective shed 100, wherein the protective shed 100 includes:

[0038] Support columns, set upright in pairs on the ground;

[0039] A stand 130 is fixed to the top of each support column to form at least three anchoring points with a high middle and low sides;

[0040] The first tie rope 140 is tied between the corresponding tie points of the top frames 130 of the two pairs of support columns to form a roof frame composed of a plurality of first tie ropes 140 with a high middle and low sides; and

[0041] A protective film is covered on the roof frame to form the roof;

[0042] The first tie rope 140 is movably installed on the tie node, and the height of the roof frame can be lowered by loosening the first tie rope 140 to facilitate covering the protective film.

[0043] The roof frame of the protective shed 100 of the utility model is composed of a plurality of first tie ropes 140 tied between corresponding tie points on the stand 130 at the top of two pairs of support columns. Compared with the traditional steel structure roof frame, the roof frame of the present application not only has good structural strength and can stably support the protective film, but also has a simple structure, which greatly reduces the production cost. The present application can lower the height of the roof frame by loosening the first tie ropes 140, so that the planting personnel can easily install and cover the protective film without the aid of auxiliary equipment such as ladders. Therefore, the protective shed 100 of the utility model is not only suitable for operators of different heights, but also convenient to install and disassemble the protective film. The protective film can be quickly disassembled and assembled according to the climate and weather conditions, and a sunshade film or a rainproof film can be arbitrarily selected to provide the best protection for the crops placed in the planting device under the protective shed 100, so as to improve the quality and yield of the crops. In addition, the protective shed 100 has a simple structure and is easy to operate without the aid of other auxiliary tools.

[0044] In some embodiments, Figure 2 and Figure 4As shown, each pair of the support columns includes a first support column 110 and a second support column 120, and the stand 130 is a first support rod 131, a second support rod 132 and a third support rod 133 fixed to the top of each support column and installed in a triangular shape. The support columns and the stand 130 provide stable support for the entire protective shed 100. The first tie rope 140 includes a first plastic steel rope 141 tied between the tops of the first support column 110 and the second support column 120, a plurality of second plastic steel ropes 142 tied between the paired first support rods 131, and a plurality of third plastic steel ropes 143 tied between the paired second support rods 132. The lengths of the first plastic steel rope 141, the second plastic steel rope 142 and the third plastic steel rope 143 are greater than the spacing between the first support column 110 and the second support column 120, so that when they are relaxed, the height of the shed roof frame can be lowered to facilitate covering the protective film. Specifically, a slide groove 111 and a rope winding drum 112 are respectively provided at the top and the middle of the first support column 110; one end of the first plastic steel rope 141 is fixed to the second support column 120, and the other end passes through the slide groove 111 at the top of the first support rod 131 and is detachably fixed to the rope winding drum 112; one end of the second plastic steel rope 142 and the third plastic steel rope 143 are respectively fixed to the first support rod 131 and the second support rod 132 at the top of the second support column 120, and the other end passes through the through holes on the first support rod 131 and the second support rod 132 fixed on the top of the first support column 110, and is detachably fixed to the rope winding drum 112. By removing the first plastic steel rope 141, the second plastic steel rope 142 and the third plastic steel rope 143 from the rope winding drum 112 and loosening them, the height of the roof frame can be lowered, so that operators of different heights can install the protective film on the roof frame when standing normally, without the need for auxiliary equipment such as ladders; when one end of the protective film is installed on the first tie rope 140, the roof frame can be quickly raised by tightening the first plastic steel rope 141, the second plastic steel rope 142 and the third plastic steel rope 143 and fixing their ends on the rope winding drum 112, thereby adjusting the installation height of the protective film. The present application sets the first tie rope 140 constituting the roof frame as a plastic steel rope. On the one hand, it is easy to realize the lifting and lowering of the top of the protective shed 100 and facilitate the installation of the protective film. On the other hand, the plastic steel rope not only has a high material strength and can well bear the weight of the protective film, but also has a low price. Compared with the prior art of laying steel bars on the top, it is not only easy to install, but also greatly reduces the production cost.

[0045] As an example, Figure 2As shown, the first tie rope 140 includes a first plastic steel rope 141, a second plastic steel rope 142 and a third plastic steel rope 143, and the three plastic steel ropes form a roof frame with a high middle and low sides. One end of the first plastic steel rope 141 is fixed to the second support column 120, and the other end passes through the slide groove 111 at the top of the first support rod 131 and is detachably fixed to the rope winding disk 112; the two ends of the second plastic steel rope 142 and the third plastic steel rope 143 are respectively fixedly connected to the first support rod 131 and the first support rod 132 at the top of the second support column 120, and the installation height of the second plastic steel rope 142 and the third plastic steel rope 143 is a height at which the operator can operate normally when standing on the ground. Therefore, the height of the top of the scaffolding can be lowered by only adjusting the height of the first plastic steel rope 141, which is convenient for the installation of the protective film.

[0046] As an embodiment, the stand 130 includes a first support rod 131 and a second support rod 132 welded to the top of each support column, one end of the first support rod 131 and the second support rod 132 are welded to the top of the support column, and the other end is tilted downward to form a structure that is high in the middle and low on both sides.

[0047] In some embodiments, the protective film can be slidably mounted on the first tie rope 140, and the protective shed 100 further includes a traction device 150 for driving the protective film to slide along the first tie rope 140. The traction device 150 includes a traction rope 151 that can be pulled between the first support column 110 and the second support column 120 and a plurality of connection ropes 152 with one end fixed to the traction rope 151 and the other end slidably connected to the first tie rope 140. The two ends of the traction rope 151 extend out of the first support column 110 and the second support column 120, respectively. Figure 2 and Figure 5As shown, the first support column 110 and the second support column 120 are provided with rope holes 113, and the two ends of the traction rope 151 are respectively installed on the first support column 110 and the second support column 120, and the two ends extend out of the rope holes 113 respectively. When the ends of the traction rope 151 are pulled, the traction rope 151 can move in the rope holes 113. The first tie rope 140 is connected to the traction rope 151 through a connecting rope 152. Specifically, one end of the connecting rope 152 is fixedly connected to the traction rope 151, and the other end is slidably installed on the first plastic steel rope 141, the second plastic steel rope 142 and the third plastic steel rope 143 through a first connecting ring 153. The first connecting ring 153 is connected with a lock buckle 155 through a second connecting ring 154, and the lock buckle 155 is used to connect the protective film. The protective film is fixed to the first tie rope 140 through the first connecting ring 153, which can ensure the freedom of movement of the protective film along the first tie rope 140; the lock buckle 155 and the first connecting ring 153 are connected through the second connecting ring 154, so that the protective film can rotate freely on the first connecting ring 153 for position adjustment, which can further improve the convenience of operation.
