Description

Technical Field

[0001] This invention relates to the field of agricultural breeding technology, specifically to a soybean breeding shed with adjustable ventilation and temperature control. Background Technology

[0002] In soybean breeding, factors such as temperature and humidity are key environmental factors affecting seed germination, growth and development, and final yield. Artificial intelligence greenhouses can meet these requirements, but their construction costs are high. When biological breeding is used for small-scale hybridization combinations, it can lead to significant waste. At the same time, if the artificial intelligence greenhouse is too large, it can affect light and cause soybeans to grow unhealthily. Building breeding sheds is inexpensive, economical, and offers flexible and convenient location selection. It also allows for better control of light, ensuring that soybean growth is consistent with that in the field, which is beneficial for hybridization breeding.

[0003] A breeding shed includes support poles and a shed cloth laid on the support poles. For ventilation, cooling, and dehumidification, windows are typically opened in the shed cloth. Furthermore, for automatic ventilation control, a control mechanism is usually installed at the windows. For example, Chinese utility model patent CN222707133U discloses an agricultural planting greenhouse, including a greenhouse frame, a first connecting lug, a horizontal mounting plate, a merging rotating plate, a side mounting plate, a fixed base plate, a rotation limit frame, a cylinder, a first rotating shaft, and windows. The greenhouse frame has a greenhouse door frame on its side, and the merging rotating plate is inserted into the side of the greenhouse frame. The side of the rotating plate is connected to the side mounting plate. A set of side mounting plates are distributed on the side of the rotating plate. The No. 1 connecting ear is connected to the greenhouse frame. Two sets of No. 1 connecting ears are symmetrically arranged on both sides of the greenhouse frame. The side of the side mounting plate is in contact with the No. 1 connecting ear. The side mounting plate is connected to the No. 1 connecting ear through the No. 4 rotating shaft. The rotating plate has multiple inner frames. The windows are installed in the inner frames of the rotating plate. The rotating plate is symmetrically arranged at both ends of the greenhouse frame. The upper part of the rotating plate has a rotating plate top. The symmetrical rotating plate tops are in contact with each other. The front and rear sides of the rotating plate top are in contact with the greenhouse frame.

[0004] This structure requires a certain connecting structure to be set on the canopy. This part of the structure will affect the storage of the entire support rod and the canopy, and may also easily cause scratches to the canopy during storage.

[0005] Therefore, the present invention provides a soybean breeding shed with adjustable ventilation and temperature control to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a soybean breeding shed with adjustable ventilation and temperature control. The problem to be solved is: to provide a soybean breeding shed with adjustable ventilation and temperature control that facilitates ventilation, cooling and dehumidification, and does not affect storage.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A soybean breeding shed with adjustable ventilation and temperature control includes several support rods and a shed cloth. The support rods are slidably provided with a first sliding member near their ends for fixed connection with the shed cloth. The support rods are provided with a movable member facing the shed cloth above the first sliding member. The movable member is connected to a push-pull member by a ball screw at the end facing the shed cloth. The push-pull member is connected to a push rod at the end facing the shed cloth. The push-pull member is provided with a transmission block around its periphery and is rotatably inserted through the transmission block. The upper and lower sides of the transmission block are respectively hinged to a first transmission rod and a second transmission rod. The support rods are respectively provided with a second sliding member and a third sliding member that are hinged to the first transmission rod and the second transmission rod.

[0009] In its natural state, the push rod is far away from the canopy. When the second and third sliding parts are controlled to move, the push rod is driven to rotate and move closer to the canopy.

[0010] Preferably, the movable part is a telescopic structure, including multiple layers of sleeves, with limiting springs between the multiple layers of sleeves. The push-pull part rotates within a certain range. When the push-pull part drives the push rod close to the tarpaulin, the push-pull part rotates first. When the push-pull part drives the push rod away from the tarpaulin, the push-pull part rotates last.

[0011] Preferably, the transmission block is provided with an annular groove on the periphery of the push-pull member, a stop block is provided in the annular groove, and a protrusion corresponding to the annular groove is provided on the periphery of the push-pull member.

[0012] Preferably, the annular groove is provided with two stops, which are 90° apart. The rotation angle of the push-pull component is 0~90°. When the angle is 0°, the push rod is away from the canopy and is in a vertical direction. When the angle is 90°, the push rod is close to the canopy and is in a horizontal direction.

[0013] Preferably, when the second and third sliding members approach each other, the push rod approaches the canopy, and the system also includes a control mechanism, which includes a lifting rod located between the third and first sliding members on one side.

[0014] Preferably, it also includes a fixed base plate, which is fixedly and detachably connected to several support rods at the same end, and the fixed base plate is provided with an electric telescopic rod connected to the lifting rod.

[0015] Preferably, the fixed base plate is provided with an insertion hole that matches the end of the support rod, the support rod is provided with a fixing plate near the end, and the fixed base plate is also provided with a fixing hole for fixing to the ground.

[0016] Preferably, the first sliding member is detachably connected to the canopy, and the support rod is detachably connected to the canopy.

[0017] There are some from Xi'an, where the movable parts and support rods can be detachably connected.

[0018] Preferably, the support rod includes an arc-shaped portion at the top and vertical portions on both sides.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. In this invention, by controlling the push rod to move close to the canopy, the push rod rotates adaptively and pushes the canopy, thereby raising the lower end of the canopy, thus achieving ventilation, cooling and dehumidification. When storing, the push rod can rotate adaptively to keep its direction corresponding to the support rod, so as not to affect the proximity of several support rods to each other during storage, and to avoid scratching the canopy.

[0021] 2. In this invention, when ventilation is carried out, the bottom of the shed cloth is affected by the first sliding member, which can form an inclined ventilation channel. At the same time, since ventilation is carried out at the bottom, ventilation efficiency and air exchange efficiency can be improved, and dead air corners inside the shed can be reduced.

[0022] 3. In this invention, the canopy fabric is less prone to wrinkles during ventilation due to the action of the push rod. Furthermore, this invention eliminates the need to open windows in the canopy fabric, thereby improving its integrity and providing better overall airtightness when ventilation is not required.

[0032] The following will refer to the attached reference. Figures 1 to 8 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] Example 1

[0034] A soybean breeding shed with adjustable ventilation and temperature control, as shown in the attached document. Figure 1 As shown, it includes several support rods 2 and a canopy 1. The support rods 2 are arranged in the front-to-back direction, and the canopy 1 is laid on the support rods 2. The left and right ends of the canopy 1 hang down to the ground. For specific use, the canopy 1 is covered on the front and back sides, and then a door is installed for normal use. This part is existing technology and will not be described in detail here.

[0035] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the support rod 2 has a first sliding member 8 slidably provided near its end for fixed connection with the canopy 1. The support rod 2 has a movable member 13 above the first sliding member 8 facing the canopy 1, that is, the movable member 13 is in the left and right direction. The end of the movable member 13 facing the canopy 1 is connected to a push-pull member 12 by ball screw thread. The end of the push-pull member 12 facing the canopy 1 is connected to a push rod 3. The push-pull member 12 has a transmission block 5 around its periphery and is rotatably inserted through the transmission block 5. The upper and lower sides of the transmission block 5 are respectively hinged to a first transmission rod 4 and a second transmission rod 6. The support rod 2 is respectively provided with a second sliding member 11 and a third sliding member 7 that are hinged to the first transmission rod 4 and the second transmission rod 6.

[0036] Working principle: In its natural state, the push rod 3 is away from the fabric 1, and at this time the push rod 3 does not act on the fabric 1. The fabric 1 and the first sliding member 8 hang down naturally under the action of gravity. When the second sliding member 11 and the third sliding member 7 are controlled to move, the first transmission rod 4 and the second transmission rod 6 can be moved, thereby driving the transmission block 5 and the push-pull member 12 to move closer to the fabric 1. When the push-pull member 3 moves closer to the fabric 1, it will rotate to a certain extent due to the action of the ball thread connection.

[0037] In addition, it should be noted that in this embodiment, the end of the movable part 13 connected to the push-pull part 12 can move left and right, so that the push-pull part 12 can move left and right, and should be provided with a certain damping so that the push rod 3 rotates first when it approaches the tarpaulin 1.

[0038] In addition, it should be noted that, in specific use, this embodiment can be used in conjunction with temperature and humidity sensors and other intelligent monitoring devices to simultaneously control the movement of the second sliding member 11 and the third sliding member 7, thereby achieving intelligent ventilation control.

[0039] This embodiment enables ventilation, cooling, and dehumidification. During storage, the push rod 3 can rotate adaptively to maintain its direction aligned with the support rod 2, thus preventing the support rods 2 from approaching each other during storage and avoiding scratches on the canopy 1. In this embodiment, during ventilation, the bottom of the canopy 1, influenced by the first sliding member 8, forms an inclined ventilation channel, as shown in the attached diagram. Figure 7 As shown, since ventilation is located at the bottom, it can improve ventilation efficiency and air exchange efficiency inside the shed, and reduce dead air corners inside the shed; in this embodiment, during ventilation, due to the action of the push rod 3, the state of the shed cloth 1 can also be referred to the attached figure. Figure 7 This makes the canopy fabric 1 less prone to wrinkles, and in this embodiment, there is no need to open windows in the canopy fabric 1, which can improve the integrity of the canopy fabric 1 and provide better overall airtightness when there is no ventilation.

[0040] Example 2

[0041] As attached Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the movable part 13 in this embodiment is a telescopic structure, including multiple layers of sleeves. A limiting spring 14 is provided between the multiple layers of sleeves. The spring 14 generates a damping effect, and the push-pull part 12 rotates within a certain range. When the push-pull part 12 drives the push rod 3 close to the tarpaulin 1, the push-pull part 12 rotates first, and the movable part 13 does not move. When the push-pull part 12 rotates to the maximum angle, it cannot continue to rotate, and then drives the movable part 13 to move together. When resetting, when the push-pull part 12 drives the push rod 3 away from the tarpaulin 1, the push-pull part 12 does not rotate first, and drives the movable part 13 to reset. After the movable part 13 resets, it remains stationary under the action of the spring 14, and the push-pull part 12 rotates to reset.

[0042] In this embodiment, the push rod 3 can rotate before contacting the fabric 1, and can leave the fabric 1 before rotating back to its original position. This ensures that the push rod 3 will not rotate with the fabric 1 when it contacts it, thus preventing damage to the fabric 1 when the push rod 3 rotates.

[0043] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, in this embodiment, the transmission block 5 is provided with an annular groove 15 on the periphery of the push-pull member 12. A stop block 16 is provided in the annular groove 15. A protrusion 17 corresponding to the annular groove 15 is provided on the periphery of the push-pull member 12. When the push rod 12 rotates, the protrusion 17 contacts the stop block 16 and stops rotating. In this embodiment, two stops 16 are provided in the annular groove 15. The two stops 16 are 90° apart. When the push-pull member 12 rotates, the protrusion 17 moves between the two stops 16. That is, the rotation angle of the push-pull member 12 is 0~90°. When it is 0°, the push rod 3 is away from the canopy 1 and is in a vertical direction. In this state, the push rod 3 occupies less front and back space. When it is stored, several support rods 2 approach each other in the front and back direction, and the push rod 3 will not have any impact. When it is 90°, the push rod 3 is close to the canopy 1 and is in a front and back horizontal direction. In this state, when several push rods 3 push the canopy 1, they can cooperate with each other so that the canopy 1 can maintain a smooth state during ventilation and will not wrinkle.

[0044] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, in this embodiment, when the second sliding member 11 and the third sliding member 7 approach each other, the push rod 3 approaches the canopy 1. It also includes a control mechanism, which includes a lifting rod 10 located between the third sliding member 7 and the first sliding member 8 on one side. When the lifting rod 10 rises, it drives the third sliding member 7 to rise. The push rod 3 approaches the canopy 1 and pushes the canopy 1. When the lifting rod 10 falls to a certain height, it can also limit the first sliding member 8, thereby limiting the bottom of the canopy 1 and preventing the bottom of the canopy 1 from lifting up.

[0045] As attached Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, this embodiment also includes a fixed base plate 9, which is fixedly and detachably connected to several support rods 2 at the same end. That is, a total of two fixed base plates 9 are provided on the left and right sides. The fixed base plate 9 is provided with an electric telescopic rod 18 connected to the lifting rod 10. In specific use, the movement of the lifting rod 10 is controlled by the electric telescopic rod 18. The fixed base plate 9 is provided with a socket adapted to the end of the support rod 2. The support rod 2 is provided with a fixing plate near the end. The fixed base plate 9 is also provided with a fixing hole for fixing to the ground.

[0046] In practical use, the fixed base plate 9 and the corresponding support rod 2 ends can be fixed with fixing plates first, while keeping each support rod 2 away from each other. The canopy cloth 1 is unfolded, and the lifting rod 10 is positioned in the corresponding position. Then, the lower end of the support rod 2, which passes through the fixed base plate 9, is inserted into the ground. At the same time, the fixed base plate 9 and the ground can also be fixed with a certain insertion rod through the fixing hole to realize the installation of this device. When storing, the fixed base plate 9 and the electric telescopic rod 18 can be separated from the support rod 2 for storage. After separation, it does not affect the storage of the support rod 2 and the canopy cloth 1. In this embodiment, by setting the fixed base plate 9, multiple support rods 2 can be linked and fixed, resulting in better fixing effect, less loosening, and making the entire greenhouse more stable. In addition, in this embodiment, due to the setting of the fixed base plate 9, the canopy cloth 1 is in contact with the fixed base plate 9 under the action of the first sliding member 8, resulting in better sealing.

[0047] In addition, in this embodiment, the first sliding member 8 is detachably connected to the canopy 1, and the support rod 2 is detachably connected to the canopy 1, so that the entire canopy 1 can be completely removed. When not in use for a long time, the canopy 1 can be reasonably folded and stored to prevent the canopy 1 from getting damaged, and it is also convenient to repair or replace the canopy 1 when it is damaged.

[0048] In addition, in this embodiment, the movable part 13 is detachably connected to the support rod 2. Since the movable part 13 adopts a multi-layer sleeve telescopic structure and is equipped with a spring 14, the spring 14 will become fatigued after long-term use. Through the detachable connection structure between the movable part 13 and the support rod 2, the movable part 13 can be replaced to ensure the tension of the spring 14. Specifically, the movable part 13 can be fixed to the support rod 2 with screws.

[0049] In addition, in this embodiment, the support rod 2 includes an arc-shaped part at the top and vertical parts on both sides, and the canopy 1 is formed in a corresponding state. In this embodiment, the arc-shaped part can withstand strong winds, rain and snow, and the vertical parts can directly slide the first sliding member 8, the second sliding member 11 and the third sliding member 7, and the sliding direction of each sliding member is along the vertical direction.
