Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice seed shed technology, specifically a temperature-adjustable shading shed for rice seed breeding. Background Technology
[0002] Rice breeding is mainly the process of artificially intervening in rice to cultivate new varieties with superior traits.
[0003] In the early stages of rice seed germination and seedling growth, excessive sunlight can damage the seedlings. Shading greenhouses reduce the intensity of sunlight on the seedlings, which is beneficial for their normal growth. The structure of a shading greenhouse is usually quite simple, consisting of a support frame and a covering material. The covering material has good shading performance and breathability, creating a relatively stable growing environment for the seedlings.
[0004] Traditional shade sheds typically rely on natural ventilation. During periods of strong sunlight and high temperatures, although the shade shed reduces the intensity of light, the temperature inside the shed is still higher than the suitable growth range for seedlings. During periods of low temperatures and large temperature differences between day and night, the temperature inside the shed is lower than the growth threshold for seedlings. Excessively high or low temperatures inside the shed can easily lead to slow or abnormal growth of seedlings, causing damage to the seedlings.
[0005] Therefore, this utility model provides a temperature-adjustable shading shed for rice breeding. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5As shown in the figure, an adjustable temperature shading greenhouse for rice breeding according to an embodiment of the present invention includes a support frame 1; a first greenhouse film 10 is fixedly connected to the middle of the support frame 1; the top of the support frame 1 is arc-shaped; a retraction assembly 2 is installed on the top of the support frame 1; a second greenhouse film 11 is installed in the middle of the retraction assembly 2; two fans 12 are installed in the middle of the first greenhouse film 10; an exhaust pipe 13 is fixedly connected to the middle of the fans 12; a temperature control pipe 17 is fixedly connected to the end of the exhaust pipe 13; the temperature control pipe 17 is fixedly connected to the top of the support frame 1; a water pump 14 is installed in the middle of the first greenhouse film 10; and a water inlet pipe 15 is fixedly connected to the middle of the water pump 14. A water outlet pipe 16 is fixedly connected to the middle of the water pump 14; the water outlet pipe 16 is Y-shaped; both ends of the water outlet pipe 16 are fixedly connected to the ends of the temperature control pipe 17; the temperature control pipe 17 has a heating chamber 18, a cooling chamber 101, and an exhaust chamber 102 in its middle; multiple heating wires 19 are installed in the middle of the heating chamber 18; multiple heat-conducting rods 103 are installed in the middle of the exhaust chamber 102; multiple sets of exhaust holes 104 are opened in the middle of the temperature control pipe 17; the end of the water outlet pipe 16 is located at the corresponding position of the cooling chamber 101; when operating, to control the temperature inside the shed, first turn on the two fans 12, and the fans 12 will... Airflow is discharged into the exhaust chamber 102 through the exhaust pipe 13. When heating is required inside the shed, multiple heating wires 19 are turned on to generate heat on their surfaces. The heat is transferred to the surface of the temperature control pipe 17 through multiple heat-conducting rods 103. After the airflow enters the temperature control pipe 17, it absorbs heat and its temperature rises. The hot airflow is discharged from multiple sets of exhaust holes 104. When cooling is required inside the shed, the water inlet pipe 15 is connected to the cooling water pipe, and the water pump 14 is turned on to discharge water through the water outlet pipe 16 to both ends. The water discharged from the end of the water outlet pipe 16 enters the corresponding cooling chamber 101. The cooling chamber 101 is filled with cooling water. The low temperature of the cooling water is transferred to the surface of the temperature control pipe 17 through multiple heat-conducting rods 103. The airflow absorbs the low temperature to form cold air, which is then discharged from multiple sets of exhaust holes 104, thereby controlling the temperature inside the greenhouse. The temperature inside the greenhouse can be adjusted according to actual needs. Through the above structure, multiple heat-conducting rods 103 transfer high or low temperatures, and the low or high temperature is evenly delivered to various areas inside the greenhouse through airflow, which quickly adjusts the temperature inside the greenhouse. Forced convection can accelerate heat exchange and reduce the problem of uneven temperature caused by local temperature differences.
[0025] like Figures 1 to 3As shown, the retraction assembly 2 includes two tracks 21; the two tracks 21 are fixed to both sides of the bracket 1; the two tracks 21 are arranged opposite each other; an electric pulley 22 is installed in the middle of the track 21; a positioning rod 23 is fixed to the middle of the track 21; multiple sliding blocks 24 are slidably connected to the middle of the positioning rod 23, and the number of sliding blocks 24 is even; a fixing rod 25 is fixed to the middle of every two corresponding sliding blocks 24; the second greenhouse film 11 is fixed to the middle of the multiple fixing rods 25; two magnetic blocks 26 are fixed to the side wall of the fixing rod 25; the two magnetic blocks 26 are arranged opposite each other; when working, when it is necessary to retract the second greenhouse film 11 to allow the seedlings to absorb sunlight, the electric pulley 22 is opened, causing the electric pulley 22 to move to one side in the middle of the track 21. At this time, the electric pulley 22 carries the seedlings to the side. One of the sliding blocks 24 moves, and the sliding block 24 slides in the middle of the positioning rod 23 along with the electric pulley 22. When the sliding block 24 moves to the side of the adjacent sliding block 24, the two magnetic blocks 26 stick together by magnetic attraction, continuously controlling the electric pulley 22 to move and stop it at the other end of the bracket 1, so that the second greenhouse film 11 can be opened. When the electric pulley 22 is reset, the multiple sliding blocks 24 continue to separate, so that the second greenhouse film 11 can be opened to shade the seedlings. Through the above structure, the second greenhouse film 11 can be quickly folded up and opened according to actual needs, quickly meeting the seedlings' light and shading needs. In addition, the fixing rod 25 can make the second greenhouse film 11 fold up stably when folded up, reducing the damage caused by random folding when the second greenhouse film 11 is folded up.

After the cooling water enters the cooling chamber 101 and cools the airflow, the valve is opened to allow water to flow into the drain pipe 3, and then through the multiple spray heads 31. The mist nozzle 31 sprays water into a mist to assist in cooling the greenhouse. When heat is discharged from the greenhouse, the heating lamp 33 is turned on to generate heat on its surface and assist in heating the greenhouse. At the same time, the lamp cover 32 protects the heating lamp 33. The above structure can assist in raising or lowering the temperature inside the greenhouse. The heating lamp 33 can accelerate the heat rise, so that the greenhouse can quickly reach the required temperature, reducing energy consumption. Furthermore, the mist spraying of cooling water by the mist nozzle 31 can effectively reduce direct water discharge and improve water resource utilization.
[0027] like Figure 1 and Figure 5As shown, multiple connecting rods 4 are fixedly connected to the middle of the support 1; multiple connecting rods 4 are fixedly connected to the bottom of the support 1; two insert rods 41 are fixedly connected to the middle of the connecting rods 4; multiple inclined plates 42 are fixedly connected to the middle of the insert rods 41; when the support 1 is installed underground, multiple insert rods 41 simultaneously enter the soil, and barbs are formed by multiple inclined plates 42, so that the support 1 forms a stable connection with the ground. The above structure can increase the stability of the support 1 after installation. The mechanical interlocking of the soil by multiple inclined plates 42 can reduce the problem of the support 1 swaying or tilting due to strong winds, effectively distribute the force of the support 1, and maintain the long-term stability of the support 1.
[0028] like Figure 1 and Figure 5 As shown, multiple reflectors 5 are installed on the inner wall of the first greenhouse film 10; the multiple reflectors 5 are set on the top of the corresponding insertion rods 41; during operation, when the seedlings are illuminated, the reflectors 5 are installed in designated positions to supplement the seedlings in designated areas. Through the above structure, the reflectors 5 can reflect direct or diffused light to the shaded areas, reducing the waste of light resources and reducing the problem of some leaves turning yellow due to lack of light when planting at high density.
[0029] like Figure 5 As shown, a round-faced hook and loop fastener 6 is fixed to the inner wall of the first greenhouse film 10; a barbed hook and loop fastener 61 is fixed to the middle of the reflector 5; the barbed hook and loop fastener 61 is installed in the middle of the round-faced hook and loop fastener 6; during operation, when the reflector 5 is placed in the designated position, the barbed hook and loop fastener 61 is attached to the corresponding position of the round-faced hook and loop fastener 6, so that the barbed hook and loop fastener 61 and the round-faced hook and loop fastener 6 are bonded together, and the reflector 5 is fixed. The position of the reflector 5 can be adjusted at will. Through the above structure, the position of the reflector 5 can be flexibly adjusted so that the seedlings in different positions can receive uniform light. The reflector 5 can be installed and removed quickly, and the operation is simple and fast.
[0030] like Figure 4 As shown, a filter screen 7 is provided in the middle of the exhaust hole 104; the filter screen 7 is fixed in the middle of the exhaust hole 104; during operation, the filter screen 7 intercepts dust and impurities in the external airflow into the exhaust chamber 102. The above structure can effectively reduce the accumulation of dust and impurities in the temperature control tube 17 through the exhaust hole 104, reduce the wear and scratches caused by impurities on the inner wall of the exhaust chamber 102, and reduce the blockage caused by the accumulation of dust and impurities, thus maintaining smooth airflow.
[0031] During operation, when controlling the temperature inside the greenhouse, firstly, the two fans 12 are turned on. The fans 12 discharge airflow through the exhaust pipe 13 into the exhaust chamber 102. When it is necessary to raise the temperature inside the greenhouse, multiple heating wires 19 are turned on to generate heat on their surfaces. The heat is transferred to the surface of the temperature control tube 17 through multiple heat conduction rods 103. After the airflow enters the temperature control tube 17, it absorbs heat and its temperature rises. The hot airflow is discharged from multiple sets of exhaust holes 104. When it is necessary to cool the greenhouse, the water inlet pipe 15 is connected to the cooling water pipe, and the water pump 14 is turned on to discharge water through the water outlet pipe 16 to both ends. The water discharged from the end of the water outlet pipe 16 enters the corresponding cooling chamber 101. The cooling water is stored in the cooling chamber 101, which is filled with cooling water. Multiple heat-conducting rods 103 transfer the low temperature of the cooling water to the surface of the temperature control pipe 17. The airflow absorbs the low temperature to form cold air, which is then discharged from multiple sets of exhaust holes 104, thus controlling the temperature inside the greenhouse. The temperature inside the greenhouse can be adjusted according to actual needs. When the second greenhouse film 11 needs to be retracted to allow the seedlings to absorb sunlight, the electric pulley 22 is opened, causing it to move to one side in the middle of the track 21. At this time, the electric pulley 22 moves one of the sliding blocks 24. The sliding block 24 slides along the electric pulley 22 in the middle of the positioning rod 23. When the sliding block 24 moves to the side of the adjacent sliding block 24, the two... Magnetic blocks 26 adhere to each other through magnetic attraction, continuously controlling the movement of electric pulley 22 until it stops at the other end of the support 1, thus opening the second greenhouse film 11. When controlling the electric pulley 22 to reset, multiple sliding blocks 24 continuously separate, thus opening the second greenhouse film 11 to provide shade for the seedlings. A valve is provided at the end of the drain pipe 3 near the temperature control pipe 17. After cooling water enters the cooling chamber 101 and cools the airflow, the valve is opened, allowing water to flow into the drain pipe 3. The water is then discharged as a mist through multiple spray nozzles 31, providing auxiliary cooling inside the greenhouse. When hot air is discharged from the greenhouse, the heating lamp 33 is turned on, generating heat on its surface to provide auxiliary cooling inside the greenhouse. Heating is performed while the lamp cover 32 protects the heating lamp 33. When the bracket 1 is installed underground, multiple inserts 41 simultaneously enter the soil and form barbs through multiple inclined plates 42, so that the bracket 1 forms a stable connection with the ground. When the seedlings are illuminated, the reflector 5 is installed in the designated position to supplement the seedlings in the designated area. When the reflector 5 is placed in the designated position, the bristle-faced hook and loop fastener 61 is attached to the position of the round-faced hook and loop fastener 6, so that the bristle-faced hook and loop fastener 61 and the round-faced hook and loop fastener 6 are adhered and the reflector 5 is fixed. The position of the reflector 5 can be adjusted at will. The filter screen 7 intercepts dust and impurities in the external airflow and enters the exhaust chamber 102.
