Description

Technical Field

[0001] This invention belongs to the field of seedling greenhouse technology, specifically relating to an agricultural ecological seedling greenhouse. Background Technology

[0002] A seedling greenhouse, also known as a hothouse, is a facility that allows light to pass through and can keep or heat the soil for cultivating plants. It provides a greenhouse growing season during seasons when plants are not suitable for growth, thereby increasing plant yield. It is often used for cultivating or raising seedlings of warm-loving vegetables, flowers, and trees during cold seasons.

[0003] Existing seedling greenhouses generally use a steel frame structure covered with a light-transmitting plastic film to achieve the purpose of heat preservation. This not only does not affect the light transmission of plants, but also has the advantages of low cost and reusability. However, when ventilation is needed for the plants, most existing seedling greenhouses require manual lifting of the plastic film, which is inconvenient for users. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural ecological seedling greenhouse with a simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An agricultural ecological seedling greenhouse includes multiple sets of lower supports. Each set of lower supports has a supporting frame slidably connected to its top. A driving device is installed on the inner wall of the lower supports. End sealing components are fixedly installed on both the lower supports and the supporting frame at both ends. A top sealing film is laid on the top of the supporting frame. Two sets of support plates are symmetrically arranged at both ends of the top sealing film. The bottom ends of the support plates are fixed to the supporting frame. A winding roller is rotatably connected between the two support plates in each set. A sunshade net is wound around each of the two winding rollers. A middle sealing film is fixedly connected to the outer end of the sunshade net. A magnetic counterweight is fixedly connected to the end of the middle sealing film away from the sunshade net. One end of each of the two winding rollers is connected via gear transmission. A servo motor is fixedly installed on the supporting frame. A synchronous pulley is fixedly connected to the output end of the servo motor and the end of one of the winding rollers. The two synchronous pulleys are connected via a synchronous belt. A compression sealing structure is installed on the supporting frame on both sides of the winding roller. A cleaning device is installed on the supporting frame outside the compression sealing structure. Seedling components are also installed inside the seedling greenhouse.

[0007] As a further optimization of the present invention, a support roller is rotatably connected to the outer wall of the top of the lower support, a fixing plate is installed at the bottom of multiple lower supports on the same side, a fixing hole is opened on the fixing plate, and a diagonal tie rod is fixedly connected between two adjacent lower supports on the same side.

[0008] As a further optimization of the present invention, the support frame includes an upper bracket with a U-shaped structure, the bottom end of the upper bracket being slidably inserted into the lower bracket, and a crossbeam being provided on the inner side of the top of the upper bracket, with both ends of the crossbeam being fixedly connected to the inner walls of both sides of the upper bracket.

[0009] As a further optimization of the present invention, the driving device includes a support seat fixedly installed on the inner wall of the top of the lower bracket, a reinforcing rib plate connected between the lower surface of the support seat and the inner side wall of the lower bracket, an electric telescopic rod fixedly connected to the upper surface of the support seat, and the output end of the electric telescopic rod fixedly connected to the crossbeam.

[0010] As a further optimization of the present invention, a connecting plate is fixedly installed on the top of the lower brackets at both ends, and a gantry is rotatably connected to the connecting plate. The end sealing assembly includes a door sealing film fixedly installed on the gantry, a lower end sealing film installed on the lower brackets at both ends, and an upper end sealing film installed on the upper bracket above the connecting plate.

[0011] As a further optimization of the present invention, the extrusion sealing structure includes two sets of slides fixedly mounted on the upper surface of the upper bracket at the bottom end. Each slide has a slide plate slidably connected in the inner cavity at the top end. A spring is fixedly connected between the bottom end of the slide plate and the bottom wall of the inner cavity of the slide. A pressure roller is rotatably connected between the top ends of the two slide plates located on the same side.

[0012] As a further optimization of the present invention, the cleaning device includes water spray pipes disposed on both sides of the top of the upper support. One end of the water spray pipe is sealed, and the other end is connected to a pipe joint. The end of the water spray pipe is fixedly connected to the upper support through an end plate. Multiple high-pressure nozzles are installed on the side of the water spray pipe near the upper support.

[0013] As a further optimization of the present invention, the seedling raising component includes a seedling bed set inside the greenhouse. Ear plates are fixedly installed on both outer walls of the seedling bed. A guide tube is fixedly connected to the upper surface of the ear plate, and a guide rod is fixedly connected to the lower surface of the ear plate and aligned with the guide tube. The seedling bed is divided into multiple layers. The guide rod installed on the upper seedling bed is slidably connected to the guide tube installed on the lower seedling bed.

[0014] As a further optimization of the present invention, a connecting rope is fixedly installed between the ear plates installed on the adjacent seedling beds. The length of the connecting rope is greater than the height of the guide rod and less than the total length of the guide rod and the guide tube. A suspension cable is fixedly installed on the uppermost seedling bed, and the top of the suspension cable is fixedly connected to the crossbeam.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. When ventilation is required inside the seedling greenhouse, the user can roll up the middle sealing film using the retracting roller, or pull the middle sealing film upwards using the electric telescopic rod to lift the upper support. This causes the magnetic counterweight to be pulled apart from the fixed plate and move upwards along the lower support, forming a ventilation gap to ventilate the plants inside the seedling greenhouse. No manual operation is required from the user, making it convenient to use.

[0017] 2. When the external sunlight is too strong, the servo motor can be started to drive the take-up roller to rotate in the opposite direction through the synchronous pulley and synchronous belt, so as to unwind the sunshade net wound on the take-up roller. At the same time, the user can start the electric telescopic rod installed on the support base. The electric telescopic rod extends and pushes the upper support upward, so that the unwound sunshade net can be unfolded and laid flat on the top of the upper support to shade the seedlings and prevent the seedlings from dying due to excessive sunlight.

[0018] 3. When dust adheres to the surface of the intermediate sealing film, affecting the light penetration of plants in the seedling greenhouse, the user can connect the external water supply pipe to the spray pipe through the pipe joint, input clean water into the spray pipe, and spray it onto the intermediate sealing film through the high-pressure nozzle. At the same time, the servo motor is started, and the winding roller is driven to rotate through the synchronous wheel and synchronous belt, pulling the intermediate sealing film to move and roll up. The high-pressure clean water washes away the dust and impurities attached to the intermediate sealing film, eliminating the need for the user to climb to clean it, thus enhancing safety.

[0019] 4. When the upper support is raised by the electric telescopic rod to ventilate the seedlings planted in the seedbed, the suspension cable can simultaneously pull the uppermost seedbed upward until all the connecting ropes are taut, increasing the gap between adjacent seedbeds and facilitating ventilation of the seedlings planted in the lower seedbed. After the upper support is reset, the upper seedbed slides down and resets under the guidance of the guide rod and guide tube, reducing the height of the seedbed and making it easier for staff to take care of the seedlings.

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example: Figure 3 - Figure 6As shown, an agricultural ecological seedling greenhouse includes multiple sets of lower supports 101. The top outer wall of the lower supports 101 is rotatably connected to support rollers 104 with guiding and protective functions. Fixing plates 102 are installed on the bottom of multiple lower supports 101 on the same side. Fixing holes 103 are opened on the fixing plates 102 to facilitate fixing the lower supports 101 by the fixing plates 102 and fixing holes 103. Diagonal tie rods 107 are fixedly connected between two adjacent lower supports 101 on the same side to connect multiple lower supports 101 into a whole with the fixing plates 102, so that adjacent lower supports 101 can support each other, which greatly improves the stability of the lower supports 101.

[0033] like Figure 6 As shown, each set of lower supports 101 is provided with an upper support 105 in a U-shape above it. The bottom end of the upper support 105 is slidably inserted into the top end of the lower support 101, so that the height of the support frame formed by the lower support 101 and the upper support 105 can be adjusted. A crossbeam 106 is provided on the inner side of the top of the upper support 105. The two ends of the crossbeam 106 are fixedly connected to the inner walls on both sides of the upper support 105. The setting of the crossbeam 106 can greatly improve the deformation resistance of the upper support 105.

[0034] like Figure 6 As shown, a support base 301 is fixedly installed on the inner wall of the top of each lower bracket 101. A reinforcing rib 302 is welded between the lower surface of the support base 301 and the inner side wall of the lower bracket 101 to improve the stability of the support base 301. An electric telescopic rod 303 is fixedly connected to the upper surface of the support base 301. The output end of the electric telescopic rod 303 is fixedly connected to the crossbeam 106. When the electric telescopic rod 303 is activated, the upper bracket 105 can be extended and lifted through the electric telescopic rod 303 to adjust the top height of the upper bracket 105.

[0035] like Figure 4 and Figure 5 As shown, connecting plates 201 are fixedly installed on the top of the lower supports 101 at both ends of the seedling greenhouse. A gate frame 202 is rotatably connected to the connecting plates 201. A door sealing film 203 is fixedly installed on the gate frame 202. A lower sealing film 204 is installed between the lower supports 101 and the gate frame 202 at both ends of the seedling greenhouse. An upper sealing film 205 is fixedly connected to the upper support 105 above the connecting plates 201. The door sealing film 203, the upper sealing film 205, and the lower sealing film 204 are used to seal both ends of the seedling greenhouse. When staff need to enter or exit the seedling greenhouse, they can rotate the gate frame 202 to open the doorway below the connecting plates 201 for user convenience.

[0036] like Figure 1 - Figure 5As shown, a top sealing film 413 is laid between the upper supports 105 at both ends. Two sets of support plates 401 are symmetrically arranged at both ends of the top sealing film 413. The bottom end of the support plate 401 is fixed to the upper support 105. A winding roller 402 is rotatably connected between the two support plates 401 in each set. A sunshade net 403 is wound on both winding rollers 402. An intermediate sealing film 404 is fixedly connected to the outer end of the sunshade net 403 and is slidably laid on both sides of the middle section of the support frame. A magnetic counterweight 405 is fixedly connected to the end of the intermediate sealing film 404 away from the sunshade net 403. The magnetic counterweight 405 is magnetically attracted to the fixed plate 102. By setting the intermediate sealing film 404, the top of the seedling greenhouse on both sides of the top sealing film 413 is sealed. In combination with the door sealing film 203, the lower sealing film 204, the upper sealing film 205 and the top sealing film 413, a heat preservation structure is formed to maintain the internal temperature of the seedling greenhouse.

[0037] like Figure 2 and Figure 10 As shown, two sets of slide blocks 501 are fixedly installed on the upper surface of the upper bracket 105 at both ends. The slide blocks 501 are located outside the take-up roller 402. A slide plate 502 is slidably connected in the inner cavity of the top of each slide block 501. A spring 503 is fixedly connected between the bottom end of the slide plate 502 and the bottom wall of the inner cavity of the slide block 501. A pressure roller 504 is rotatably connected between the top ends of the two slide plates 502 on the same side. The pressure roller 504 is located above the intermediate sealing film 404 and can press the intermediate sealing film 404 downward in conjunction with the pulling force of the spring 503, so that the lower surface of the intermediate sealing film 404 can fit with the upper surface of the top sealing film 413, maintaining the airtightness of the contact position between the intermediate sealing film 404 and the top sealing film 413 to reduce heat loss.

[0038] like Figure 2 - Figure 3 and Figure 7 As shown, one end of each of the two take-up rollers 402 is connected by a gear 406. A rain cover 411 is fitted around the gear 406, and the bottom end of the rain cover 411 is fixedly connected to the crossbeam 106 by a fixing block 412 to protect the gear 406. A servo motor 407 is fixedly mounted on the crossbeam 106 of the bracket 105 at one end by a mounting base 408. The output end of the servo motor 407 and the end of one of the take-up rollers 402 are both fixedly connected to a synchronous pulley 409. The step rollers 409 are connected by a synchronous belt 410. When it is necessary to ventilate the plants in the seedling greenhouse, the user can start the servo motor 407, which drives the winding roller 402 to rotate through the synchronous rollers 409 and the synchronous belt 410, and wind up the intermediate sealing film 404. At this time, the magnetic counterweight 405 located at the bottom of the intermediate sealing film 404 is pulled and separated from the fixed plate 102, and moves up along the lower support 101 to form a ventilation gap, so as to ventilate the plants in the seedling greenhouse.

[0039] On the other hand, users can also directly activate the electric telescopic rod 303 installed on the support base 301 to lift the upper support 105 to a suitable height. During the upward movement of the upper support 105, the magnetic counterweight 405 at the bottom of the middle sealing film 404 will also be pulled and separated from the fixing plate 102, and move upward along the lower support 101 to form a ventilation gap to ventilate the plants in the seedling greenhouse. No manual operation is required from the user, making it convenient to use.

[0040] When the external sunlight is too strong and shading of the plants is required, the user can start the servo motor 407, which drives the take-up roller 402 to rotate in the opposite direction through the synchronous pulley 409 and the synchronous belt 410, unwinding the sunshade net 403 wound on the take-up roller 402. At the same time, the user starts the electric telescopic rod 303 installed on the support base 301, which extends and pushes the upper support 105 upward, unfolding the unwound sunshade net 403 and laying it flat on the top of the upper support 105. This not only allows for ventilation in the seedling greenhouse during periods of strong sunlight, but also provides shading through the unfolded sunshade net 403, minimizing the risk of damage to the seedlings due to excessive sunlight.

[0041] like Figure 2 and Figure 9 As shown, water spray pipes 602 are provided on both sides of the top of the upper support 105. One end of the water spray pipe 602 is sealed, and the other end is connected to a pipe joint 603, allowing the water spray pipe 602 to be connected to an external water supply pipe. The end of the water spray pipe 602 is fixedly connected to the upper support 105 located at both ends through an end plate 601, supporting the water spray pipe 602 above the intermediate sealing membrane 404. Multiple high-pressure nozzles 604 are installed on the side of the water spray pipe 602 near the intermediate sealing membrane 404. When the surface of the intermediate sealing membrane 404 is covered with... When dust accumulates and affects the light penetration of plants in the seedling greenhouse, the user can connect the external water supply pipe to the spray pipe 602 through the pipe connector 603, input clean water into the spray pipe 602, and spray it onto the intermediate sealing film 404 through the high-pressure nozzle 604. At the same time, the user starts the servo motor 407, which drives the winding roller 402 to rotate through the synchronous pulley 409 and the synchronous belt 410, and winds up the intermediate sealing film 404. The high-pressure clean water washes away the dust and impurities attached to the intermediate sealing film 404, eliminating the need for the user to climb to clean it.

[0042] like Figure 2 and Figure 8As shown, the seedling greenhouse is equipped with seedling beds 701. Ear plates 702 are fixedly installed on both outer walls of the seedling beds 701. Guide tubes 703 are fixedly connected to the upper surface of the ear plates 702, and guide rods 704, which are aligned with the guide tubes 703, are fixedly connected to the lower surface of the ear plates 702. The seedling beds 701 are divided into multiple layers to improve space utilization. The seedling beds 701 located on the upper layer are slidably connected to the guide tubes 703 installed on the seedling beds 701 located on the lower layer through the guide rods 704. The guide tubes 703 and guide rods 704 work together to support the seedlings, so that there is enough space for seedling growth between the two adjacent layers of seedling beds 701.

[0043] A connecting rope 706 is fixedly installed between the ear plates 702 installed on the two adjacent seedling beds 701. The length of the connecting rope 706 is greater than the height of the guide rod 704 and less than the total length of the guide rod 704 and the guide tube 703. A suspension cable 705 is fixedly installed on the uppermost seedling bed 701. The top of the suspension cable 705 is fixedly connected to the crossbeam 106. When the upper support 105 is raised by the electric telescopic rod 303 to ventilate the seedlings planted in the seedling bed 701, the suspension cable 705 can simultaneously pull the uppermost seedling bed 701 upward until the multiple connecting ropes 706 are taut, increasing the gap between adjacent seedling beds 701, which facilitates ventilation of the seedlings planted in the lower seedling bed 701. After the upper support 105 is reset, the upper seedling bed 701 slides down and resets under the guidance of the guide rod 704 and the guide tube 703, reducing the height of the upper seedling bed 701 and making it easier for staff to take care of the seedlings.

[0044] It should be noted that, when using this type of agricultural ecological seedling greenhouse, firstly, the lower support 101 is fixedly installed in a suitable position using the fixing plate 102, and the bottom end of the upper support 105 is slidably inserted into the lower support 101 to form the greenhouse frame structure. Then, the user installs the door frame 202, door sealing film 203, lower sealing film 204, and upper sealing film 205 at both ends of the greenhouse frame, and installs the winding roller 402 with the sunshade net 403 and the middle sealing film 404 on the top of the greenhouse frame. Finally, the servo motor 407 and electric telescopic rod 303 and other driving components are assembled in the corresponding positions to complete the assembly of the seedling greenhouse.

[0045] When ventilation is needed for the plants in the seedling greenhouse, the user can start the servo motor 407, which drives the winding roller 402 to rotate via the synchronous pulley 409 and synchronous belt 410, winding up the intermediate sealing film 404. At this time, the magnetic counterweight 405 at the bottom of the intermediate sealing film 404 is pulled apart from the fixed plate 102 and moves upward along the lower support 101, forming an air exchange gap to ventilate the plants in the seedling greenhouse. Alternatively, the electric telescopic rod 303 installed on the support base 301 can be directly started to lift the upper support 105 to a suitable height. During the upward movement of the upper support 105, the magnetic counterweight 405 at the bottom of the intermediate sealing film 404 will also be pulled apart from the fixed plate 102 and move upward along the lower support 101, forming an air exchange gap to ventilate the plants in the seedling greenhouse. No manual operation is required from the user, making it convenient to use.

[0046] When the external sunlight is too strong and shading of the plants is required, the user can start the servo motor 407, which drives the take-up roller 402 to rotate in the opposite direction through the synchronous pulley 409 and the synchronous belt 410, unwinding the sunshade net 403 wound on the take-up roller 402. At the same time, the user starts the electric telescopic rod 303 installed on the support base 301, which extends and pushes the upper support 105 upward, unfolding the unwound sunshade net 403 and laying it flat on the top of the upper support 105. This not only allows for ventilation in the seedling greenhouse during periods of strong sunlight, but also provides shading through the unfolded sunshade net 403, minimizing the risk of damage to the seedlings due to excessive sunlight.

[0047] When dust adheres to the surface of the intermediate sealing film 404, affecting the light penetration of plants in the seedling greenhouse, the user can connect the external water supply pipe to the spray pipe 602 through the pipe joint 603, input clean water into the spray pipe 602, and spray it onto the intermediate sealing film 404 through the high-pressure nozzle 604. At the same time, the user starts the servo motor 407, which drives the winding roller 402 to rotate through the synchronous pulley 409 and the synchronous belt 410 to wind up the intermediate sealing film 404. The high-pressure clean water washes away the dust and impurities adhering to the intermediate sealing film 404, eliminating the need for the user to climb to clean it.

[0048] When the upper support 105 is raised by the electric telescopic rod 303 to ventilate the seedlings planted in the seedbed 701, the suspension cable 705 can simultaneously pull the uppermost seedbed 701 upwards until the multiple connecting ropes 706 are taut, increasing the gap between adjacent seedbeds 701, which facilitates ventilation of the seedlings planted in the lower seedbeds 701 and greatly improves the ventilation effect.

[0049] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
