Description

Technical Field

[0001] The invention relates to the technical field of greenhouses, in particular to greenhouses used for ecological agricultural planting. Background Art

[0002] Greenhouses are widely used in ecological agriculture. Generally speaking, greenhouses can prevent wind, rain, snow and other weather from damaging plants, and prevent the invasion of pests and pathogens, which is conducive to plant growth and yield improvement, and achieves an extended planting season. For the use of greenhouses, in short, it can better control the growth environment of plants, such as effectively controlling environmental factors such as temperature, humidity, light, soil moisture, etc., so as to increase the growth rate and yield of crops. Among them, the control of light is a major environmental optimization factor. The greenhouse film used in the greenhouse has different light transmittances, which can itself change the amount of light received by the crops in the greenhouse. However, the current greenhouse film can only change the light by relying on the material of the greenhouse film itself and whether to add corresponding coverings. The flexibility of adjusting the light is relatively low. Moreover, due to geographical reasons, in the same greenhouse, one side may receive much less light and intensity than the other side during the day. For example, the light on both sides in the east-west direction is different, resulting in obvious differences in the production situation of crops on both sides of the greenhouse, especially for crops that are more sensitive to light demand. This differential light is very unfavorable for field management.

[0003] In actual production, in order to make up for this defect, corresponding fill lights are added in the greenhouse to change the difference in lighting duration and intensity. However, this requires a series of facilities to complete and wastes a lot of electricity. For agricultural production, it is actually not energy-saving and efficient, and it is difficult to meet the requirements of green energy conservation in ecological agriculture. Summary of the invention

[0004] The purpose of the present invention is to provide a greenhouse for ecological agricultural planting, which solves the technical problem that the existing greenhouse itself is difficult to flexibly adjust the lighting.

[0005] To achieve the above-mentioned purpose, the greenhouse for ecological agricultural planting adopted by the present invention includes a greenhouse body covered on the ground, and the greenhouse body includes two light-transmitting plates arranged opposite to each other on the left and right. The top ends of the two light-transmitting plates are hinged together, and the bottom ends of the light-transmitting plates are far away from each other so that the two light-transmitting plates and the ground form a triangle, and the bottom ends of the two light-transmitting plates can be relatively close to or away from each other. A reflective plate for reflecting light onto the light-transmitting plate is also provided on the side of each light-transmitting plate facing away from the interior of the greenhouse.

[0006] Furthermore, the light-transmitting plate is embedded with a light-transmitting reflective plate that can be separated from the light-transmitting plate, so that the reflective plate and the light-transmitting plate form a V-shaped angle layout, and the length of the reflective plate must be such that the light above the shed can be directly hit by the reflective plate and then reflected by the reflective plate to the light-transmitting plate where it is located.

[0007] Furthermore, a mounting cavity is provided on the side of the light-transmitting plate facing the sky for the entire reflective plate to be embedded therein, and a hinge hole is provided at each of the front and rear ends of the side of the mounting cavity facing the ground, and a plurality of screw holes are provided around the hinge hole;

[0008] A hinge shaft is fixed on one side of the reflective plate, and a plurality of threaded holes corresponding to the screw holes are arranged around both ends of the hinge shaft, so that when the bolts are fixed in the screw holes and the threaded holes, the reflective plate is fixed at a predetermined position with a corresponding angle to the light-transmitting plate.

[0009] Furthermore, the reflective plate is an elastically retractable plate, and its extended plate section is pressed against the top of the installation cavity, so that the reflective plate will not be separated from the installation cavity;

[0010] A lifting ring is fixed on the top of the protruding plate section, and the lifting ring is wound around a wheel after passing through a fixed pulley through a steel wire rope. When the wheel is rotated to store the steel wire rope, a part of the protruding plate section of the reflective plate in the light-transmitting plate can be compressed into the reflective plate, so that the reflective plate at this time can be flipped out of the installation cavity under the subsequent pulling of the steel wire rope.

[0011] Furthermore, the bottom ends of the two oppositely arranged light-transmitting plates are connected by a pair of screws with opposite rotation directions and a sleeve. One end of the screw is threadedly installed in the sleeve, and the other end of the screw is in a rectangular column structure and axially inserted in a torque-limiting tube seat. The torque-limiting tube seat is fixed to the bottom end of the inner side of the light-transmitting plate, so that when the sleeve is rotated, the two screws move away from or closer to each other to change the angle between the two light-transmitting plates.

[0012] Furthermore, the torque-limiting pipe seat is fixed to the side of an L-shaped support block, the bottom of the support block is installed on a base fixed to the ground through rollers, and can move left and right in the base, and an N-shaped rotating frame is hinged at the free end of the base. When the rotating frame rotates to a vertical plane, the locking bolt passes through the top of the rotating frame and is tightened on the support block located in the rotating frame.

[0013] Furthermore, the wheel disc is rotatably mounted on the top end of the locking bolt, and the fixed pulley is mounted on the upper surface of the support block.

[0014] Furthermore, a support member is fixed to the bottom end of the light-transmitting plate, and the support member is horizontally slidably installed in a base member, and the base member is fixed on the ground. The support member slides in a horizontal slide groove in the base member, and is threadedly mounted on a lead screw rotatably installed in the horizontal slide groove. A section of the lead screw is located outside the side of the base member, so that when the lead screw is rotated, the support member moves left and right.

[0015] Furthermore, the base member is in a G-shape, and the bottom end of the vertical section is a blade-like structure that can be inserted into the ground.

[0016] The core principle of the greenhouse for ecological agricultural planting of the present invention is very simple and the structure is easy to implement. It uses a hinged light-transmitting plate as a greenhouse film. By changing the inclination of the light-transmitting plate, the amount of effective light entering the greenhouse can be directly changed. At the same time, a reflective plate specifically for reflecting light is provided. When necessary, the light is reflected from the backlight side into the greenhouse, thereby reducing the difference in uneven lighting on both sides of the greenhouse.

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1As shown in the structure, the greenhouse used for ecological agricultural planting mainly includes a greenhouse body covered on the ground. Specifically, the greenhouse body includes two light-transmitting panels 1 arranged opposite to each other on the left and right. The top ends of the two light-transmitting panels 1 are hinged together, and the bottom ends of the light-transmitting panels 1 are far away from each other, so that the two light-transmitting panels 1 and the ground form a triangular area, and the bottom ends of the two light-transmitting panels 1 can be relatively close to or away from each other to adjust the inclination angle of the two relative light-transmitting panels 1 to adapt to the light at different times, so as to weaken or enhance the light that the crops in the greenhouse can receive, thereby starting from the light to achieve the purpose of flexibly controlling the growth of crops.

[0028] As a specific implementation structure, such as Figure 1 A light-transmitting reflective plate 2 that can be separated from the light-transmitting plate 1 is embedded in the light-transmitting plate 1, so that the reflective plate 2 and the light-transmitting plate 1 form a V-shaped angle layout. The length of the reflective plate 2 must be such that the light above the shed body can be directly reflected by the reflective plate 2 to the light-transmitting plate 1 where it is located, so that even in the morning or afternoon, the side facing away from the sun can receive a certain amount of light, avoiding a large difference in the production status of crops on both sides.

[0029] In more detail, in practice, Figure 3 and Figure 5 The light-transmitting plate 1 is provided with a mounting cavity 9 for the reflector 2 to be integrally embedded on the side facing the sky. The mounting cavity 9 can be rectangular, and the reflector 2 is also a rectangular plate. A hinge hole 10 is provided at each of the front and rear ends of the side of the mounting cavity 9 facing the ground. A plurality of screw holes 11 are provided around the hinge hole 10, preferably in a uniform annular array. At the same time, if Figure 4 and Figure 6 A hinge shaft 12 is fixed on one side of the reflective plate 2, and a number of threaded holes corresponding to the screw holes 11 are arranged around both ends of the hinge shaft 12, so that when the bolts are fixed in the corresponding screw holes 11 and the threaded holes, the reflective plate 2 is fixed at a predetermined position with a corresponding angle to the light-transmitting plate 1, so that the light above the greenhouse can be reflected by the reflective plate 2 and enter the shed on the right side of the greenhouse. By rotating the reflective plate 2 to different positions, the amount of reflected light can be changed, thereby adjusting the amount of light reflection and obtaining appropriate reflected light.

[0030] like Figure 2 , Figure 4 As shown, the reflective plate 2 is an elastically retractable plate, which can be retracted up and down along the inclined direction of the light-transmitting plate 1. The protruding plate segment 5 is pressed against the top of the installation cavity 9, so that the reflective plate 2 will not be separated from the installation cavity 9. If necessary, a corresponding step can be set at the end of the protruding plate segment 5 to ensure that the surface of the overall plate-like structure formed after the reflective plate 2 is embedded in the light-transmitting plate 1 is flush.

[0031] In addition, when making Figure 1-2 , Figure 4 as well as Figure 7 A lifting ring 4 can also be fixed on the top of the extended plate section 5. The lifting ring 4 is wound around a fixed pulley 14 through a steel wire rope 3 and then wound on a wheel 13. When the wheel 13 is rotated to store the steel wire rope 3, a part of the extended plate section 5 of the reflective plate 2 in the light-transmitting plate 1 can be compressed into the reflective plate 2. After being compressed, the reflective plate 2 can naturally be pulled out of the installation cavity 9 by the subsequent pulling of the steel wire rope 3, that is, turned out of the light-transmitting plate 1, so as to achieve the light supplement effect of reflecting the light above the greenhouse into the backlight side.

[0032] like Figure 1 and Figure 7 In the structure shown, the bottom ends of the two oppositely arranged light-transmitting plates 1 can be connected by a pair of screw rods 6 with opposite rotation directions and a sleeve 7. The sleeve 7 can be rotated in situ, which can be manual or electric. The corresponding installation structure can be adaptively designed by a person skilled in the art. One end of the screw rod 6 is threadedly installed in the sleeve 7, and the other end of the screw rod 6 is a rectangular column structure, which is axially inserted in a torque-limiting tube seat 21. This torque-limiting tube seat 21 is fixed to the bottom end of the inner side of the light-transmitting plate 1 to prevent the screw rod 6 from rotating. Therefore, when the sleeve 7 is rotated, the two screw rods 6 can move away from each other or get closer to each other, so as to change the angle between the two light-transmitting plates 1, that is, adjust the inclination of the light-transmitting plate 1, change the amount of light incident into the greenhouse, and together with the reflector 2 whose inclination angle can also be adjusted, more flexibly control the amount of light in the greenhouse.

[0033] like Figure 1 The torque limiting tube seat 21 is fixed to the side of an L-shaped support block 8, such as Figure 7 The bottom of the support block 8 is mounted on a base 15 fixed to the ground through rollers, and can move left and right in the base 15 to adapt to the change of the inclination of the light-transmitting plate 1. At the same time, an n-shaped rotating frame 16 is hinged at the free end of the base 15. When the rotating frame 16 rotates to a vertical plane, the locking bolt 17 passes through the top of the rotating frame 16 and firmly presses on the support block 8 located in the rotating frame 16 to help fix the support block 8. When making, it is recommended to rotatably install a wheel disc 13 on the top of the locking bolt 17, and the fixed pulley 14 is installed on the upper surface of the support block 8 to obtain a compact structure.

[0034] As a specific implementation structure of the present invention, in terms of the adjustment structure of the inclination of the light-transmitting plate 1, in addition to the above structure, a support member 18 may be fixed at the bottom end of the light-transmitting plate 1, such as Figure 8The support member 18 is horizontally slidably installed in a base member 19, and the base member 19 is fixed on the ground. The support member 18 slides in a horizontal groove in the base member 19, and is threadedly mounted on a lead screw 20 rotatably installed in the horizontal groove. A section of the lead screw 20 is located outside the side of the base member 19, so that when the lead screw 20 is rotated, the support member 18 moves left and right to change the inclination of the light-transmitting plate 1. Compared with the structural design of the lead screw 6 mentioned above, the design adjustment here is more complicated, but it can achieve the adjustment of two different inclinations of the light-transmitting plate 1 relative to each other, and it is more flexible. In order to improve the stability of the greenhouse installation, continue to refer to Figure 8 The base member 19 is in the shape of a letter G, and the bottom end of the vertical section is a blade-like structure that can be inserted into the ground, so that it can be quickly inserted into the soil and firmly fixed after being wedged.

[0035] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
