Description

Technical Field

[0001] This utility model relates to the field of seedling greenhouse technology, and in particular to a seedling greenhouse with humidity regulation function. Background Technology

[0002] Seedling cultivation usually requires a temperature-controlled environment, which is currently mostly carried out in greenhouses. Most greenhouses are temperature-controlled, and the internal temperature can be flexibly adjusted and controlled to meet the needs of more delicate crops or plants.

[0003] Drying through ventilation devices can regulate the humidity inside the greenhouse. For example, the existing Chinese patent announcement number "CN221329691U" discloses a ventilation structure for a vegetable greenhouse, including a main body of the greenhouse, ventilation holes on the front and rear sides of the main body, a ventilation fan fixed inside the ventilation holes, and a fixed cover connected to the outside of the ventilation holes. It also includes: active blades and driven blades rotatably connected to the inside of the fixed cover, and an active wheel fixed to one side of the active blades and passing through the fixed cover. This utility model uses two adjustable blades to adjust the air intake, which, together with the fan, can more accurately adjust the temperature inside the vegetable greenhouse. Furthermore, adjusting the closed state of the blades can ensure the airtightness of the structure and prevent external air from entering and affecting the temperature inside the greenhouse. This solves the problems of current fan ventilation methods, which cannot accurately control the air intake and temperature inside the vegetable greenhouse, and the poor airtightness of the ventilation structure, which allows external air to easily enter the greenhouse and cause unstable temperature.

[0004] In actual operation, the air intake is controlled by driving a pair of blades. However, although the blades can be driven to rotate, the control effect is not good. Furthermore, there is no filtration between the blades and the fan, and dust mixed in with the air enters the fan directly, which affects the service life of the fan over a long period of time. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor air intake control and the lack of filtration between the blades and the fan, by proposing a seedling greenhouse with humidity regulation function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a seedling greenhouse with humidity regulation function, including ventilation ducts connecting the two sides of the greenhouse body, the ventilation ducts on both sides are used for air intake and exhaust respectively through internal ventilation components, the ventilation ducts include a support frame, a number of adjusting blades are provided on the opening side of the support frame, and an adjustment mechanism for adjusting the opening and closing of the adjusting blades.

[0008] The support frame contains a filter element located between the adjusting blade and the ventilation component, which is fixed by a fixing assembly. The filter element is used to filter dust.

[0009] Furthermore, the adjustment mechanism includes an adjustment member, and the support frame is fixedly connected to the two sides of the opening on the inner wall. A support sub-plate is also fixedly connected to one side of the support frame. A sliding groove is formed between the support sub-plate and the adjacent support plate, and the adjustment member is slidably connected in the sliding groove.

[0010] Furthermore, the adjusting blade is rotatably connected between the support plates via a first connecting rod fixedly connected to both sides, and a second connecting rod is also fixedly connected to the side of the adjusting blade near the adjusting member. The adjusting member is rotatably connected to the second connecting rod via a straight groove.

[0011] Furthermore, the adjustment mechanism also includes a motor, which is fixedly connected to the side of the support frame. The output shaft of the motor is fixedly connected to an eccentric rod. The adjustment component has a straight groove II on the side away from the adjustment blade, and the free end of the eccentric rod is slidably connected in the straight groove II.

[0012] Furthermore, the fixing component includes a pair of locking blocks, the support frame is provided with a sliding groove connecting both sides, the inner sides of both sides of the sliding groove are slidably connected to the locking blocks by springs, and the bottom of the pair of locking blocks on the same side is provided with a guide slope.

[0013] Furthermore, the filter element is slidably connected within the groove, and the filter element is disposed between a pair of the locking blocks via the guide ramp, with the filter element fitting against the inner wall of the support frame.

[0014] The present invention proposes a seedling greenhouse with humidity regulation function, which has the following advantages: The present invention can adjust the opening and closing of several regulating blades through the adjustment mechanism, and can accurately control the air intake by adjusting the opening and closing size of the regulating blades. When the regulating blades are closed, it can prevent a large amount of outside air from entering the greenhouse body and causing a large temperature change. In addition, the filter is fixed by the fixing component, which is used to filter the dust blown by the wind, thereby extending the service life of the fan. Furthermore, the old filter can be replaced by a new filter with a new diameter through a contact mechanism, which is convenient, quick and practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A seedling greenhouse with humidity regulation function includes ventilation ducts 2 connecting both sides of the greenhouse body 1. The ventilation ducts 2 on both sides are connected by internal ventilation components 3 for air intake and exhaust respectively. The ventilation ducts 2 include a support frame 21, and a plurality of adjusting blades 4 are provided on the opening side of the support frame 21, as well as an adjusting mechanism 5 for adjusting the opening and closing of the adjusting blades 4.

[0024] The support frame 21 has a filter element 7 located between the adjusting blade 4 and the ventilation component 3, which is fixed by the fixing component 6. The filter element 7 is used to filter dust.

[0025] In some embodiments, a temperature sensor is also installed inside the main body 1 of the greenhouse. The temperature sensor, ventilation component 3, and motor 52 are all connected to the control terminal and power supply device.

[0026] Furthermore, the temperature inside the main body of the greenhouse 1 is detected by a temperature sensor, and water is sprayed to supplement humidity or a ventilation device is used to dry it, so the humidity can be regulated. Therefore, a water spraying device is also installed inside the main body of the greenhouse 1, and a heating device is also installed inside the support frame 21.

[0027] Furthermore, the adjustment mechanism 5 includes an adjustment member 51. Support plates 22 are fixedly connected to both sides of the opening on the inner wall of the support frame 21. A support sub-plate 23 is also fixedly connected to one side of the support frame 21. A sliding groove is formed between the support sub-plate 23 and the adjacent support plate 22. The adjustment member 51 is slidably connected in the sliding groove.

[0028] Furthermore, the adjusting blade 4 is rotatably connected between the support plate 22 via a first connecting rod 41 fixedly connected on both sides, and a second connecting rod 42 is also fixedly connected to the side of the adjusting blade 4 near the adjusting member 51. The adjusting member 51 is rotatably connected to the second connecting rod 42 via a straight groove 512.

[0029] Specifically, the second connecting rod 42 and the first connecting rod 41 are arranged vertically parallel to each other.

[0030] More specifically, the adjustment mechanism 5 also includes a motor 52, which is fixedly connected to the side of the support frame 21. The output shaft of the motor 52 is fixedly connected to an eccentric rod 53. The adjustment member 51 has a straight groove 511 on the side away from the adjustment blade 4, and the free end of the eccentric rod 53 is slidably connected in the straight groove 511.

[0031] In this embodiment, the eccentric rod 53 drives the adjusting member 51 to move. The adjusting blade 4 is rotatably connected to the support plate 22 through the first connecting rod 41, and rotates in a semi-circular manner under the driving force of the adjusting member 51 and the limiting effect of the second connecting rod 42, so as to adjust the opening and closing size between the adjacent adjusting blades 4. Furthermore, the air intake or exhaust volume can be controlled more accurately through the adjustment action, and when the adjusting blades 4 are closed, a large amount of outside air can be prevented from entering the greenhouse body 1 and causing a large temperature change.

[0032] Of course, in order to ensure that the adjusting member 51 remains stable when sliding, guide grooves and guide blocks are respectively provided between the two inner sides of the slide groove and the adjusting member 51. The guide grooves and guide blocks are slidably connected, and the adjusting member 51 can make a small circumferential swing within the slide groove.

[0033] In general, the fixing component 6 includes a pair of locking blocks 61, the support frame 21 is provided with a sliding groove 24 connecting both sides, and the inner sides of the sliding groove 24 on both sides are slidably connected to the locking blocks 61 by springs 62. The bottom of the pair of locking blocks 61 located on the same side is provided with a guide slope 63.

[0034] Finally, the filter element 7 is slidably connected in the groove 24, and the filter element 7 is disposed between a pair of the locking blocks 61 via the guide slope 63, and the filter element 7 is in contact with the inner wall of the support frame 21.

[0035] Specifically, the filter element 7 is disposed between a pair of the card blocks 61 for filtering dust. When the filter element 7 needs to be replaced, the old filter element 7 can be pushed out by the new filter element through a pushing and resisting action.

[0036] Among them, because a pair of locking blocks 61 are located on the same side of the bottom with a guide slope 63, on the one hand, it is convenient to push in the filter element 7, and on the other hand, the filter element 7 can also be disengaged from the support frame 21 through the guide slope 63 on the other side.

[0037] Working method: During operation, the temperature inside the main body 1 of the greenhouse is detected by a temperature sensor, and the temperature inside the greenhouse is reduced by a water spraying device. When it is necessary to increase the temperature, the ventilation component 3 works in conjunction with the heating device to increase the temperature of the greenhouse body.

[0038] Among them, the motor 52 drives the eccentric rod 53 to rotate. The shaft end of the eccentric rod 53 drives the adjusting component 51 to move along the slide groove through the straight groove 511. While the adjusting component 51 moves, it cooperates with the second connecting rod 42 to drive several adjusting blades 4 to rotate half a revolution. When the several adjusting blades 4 are closed, they can prevent outside air from entering the shed. Furthermore, the air intake or exhaust volume can be adjusted by adjusting the opening and closing size between the adjacent adjusting blades 4.

[0039] When the filter element 7 needs to be replaced, the old filter element 7 can be pushed out by the new filter element through the pushing and resisting method. The new filter element 7 is placed between a pair of locking blocks 61 through the guide slope 63.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
