Description

Technical Field

[0001] The invention relates to the technical field of low-temperature seedling hardening, and in particular to a low-temperature seedling hardening device for cultivating cowpea. Background Art

[0002] Low-temperature hardening of cowpea seedlings is a seedling cultivation technology that artificially controls the ambient temperature to allow the cowpea seedlings to undergo a period of low-temperature adaptation before transplanting. This technology is usually carried out 7 to 10 days before transplanting, gradually reducing the temperature of the seedbed to 10 to 15 degrees. The low-temperature stimulation enhances the stability of the seedling cell membrane, promotes root development and the expression of stress-resistant genes, and enables them to adapt to the low-temperature environment of the open field or greenhouse more quickly after transplanting, shortens the seedling hardening time, and reduces the risk of frost damage. At the same time, it can also inhibit the excessive growth of seedlings, promote short and strong plants, and thick and green leaves, laying the foundation for high and stable yields in the later period. This process needs to be combined with management measures such as water control and ventilation to avoid diseases caused by low temperature and high humidity. The intensity of seedling hardening should be flexibly adjusted according to the characteristics of the cowpea variety and local climatic conditions to ensure that the seedlings form a good physiological mechanism of stress resistance under low-temperature stress.

[0003] Existing low-temperature seedling hardening devices usually cannot truly simulate the outdoor environment, resulting in a reduced survival rate of cowpea seedlings after transplanting. Therefore, we propose a low-temperature seedling hardening device for cowpea cultivation. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a low-temperature seedling hardening device for cultivating cowpea, comprising:

[0005] A bottom plate, the top of which is fixedly connected to the cabinet body, and the inner side of the cabinet body is rotatably connected to the cabinet door via a rotating rod;

[0006] The seedling hardening mechanism is provided with two parts, and the two parts of the seedling hardening mechanism are respectively fixedly connected to the inner and outer sides of the cabinet;

[0007] Wherein, the seedling hardening mechanism includes:

[0008] A placement rack is arranged inside the cabinet, and a plurality of the placement racks are evenly distributed inside the cabinet, and the surface of the placement rack is slidably engaged with the inner side surface of the cabinet;

[0009] A supporting assembly, the supporting assembly is fixedly connected to the interior of the placement rack, and a plurality of the supporting assemblies are provided, and the plurality of the supporting assemblies are evenly distributed on the inner wall of the placement rack;

[0010] A cooling component, the cooling component is fixedly connected to the cabinet;

[0011] A water collection component is fixedly connected to the side of the bottom plate away from the cabinet, and the water collection component is in communication with the inner cavity of the cabinet, and the side of the water collection component away from the cabinet is in communication with the cooling component;

[0012] Open the cabinet door, take out the placement rack, and at the same time take out the supporting assembly, then place the pot seedlings inside the supporting assembly, fill several supporting assemblies in turn, then insert the placement rack back, then take out another placement rack, and repeat the above steps to fill all supporting assemblies, thereby realizing batch low-temperature hardening of cowpea pot seedlings, starting the cooling assembly, and blowing out low-temperature and humid air. The low-temperature air simulates the low-temperature environment after transplanting, and then by gradually lowering the ambient temperature, the seedlings adapt to the low-temperature environment, improve the cold resistance of the seedlings, and enable them to better adapt to the external low-temperature conditions after transplanting. The cooling assembly can blow out humid air. After the humid air contacts the seedlings, it condenses on the surface of its leaves, simulating the morning dew environment, and obtaining a more realistic external environment. It can not only replenish the seedlings with appropriate water, but also further enhance the low-temperature adaptation effect through water vapor evaporation and heat absorption. The condensed excess water droplets gradually drip along the layered placement racks, and finally enter the water collection assembly at the bottom of the cabinet, and then enter the cooling assembly, and are reused by the cooling assembly, while discharging excess water and realizing water circulation.

[0013] Furthermore, the cooling component includes a cooling pipe, which is configured as a serpentine shape, and the cooling pipe is arranged around the outside of several placement racks, the cooling pipe is embedded in the cabinet, and the outer side of the cooling pipe is fixedly connected to the inner side of the cabinet, the end of the cooling pipe away from the bottom plate extends to the outside of the cabinet, and the end of the cooling pipe located outside the cabinet is located on the side of the cabinet close to the cabinet door, a cooling hole is opened on the surface of the cooling pipe, and the cooling hole is arranged just above the placement rack, and the cooling pipe is connected to the inner cavity of the cabinet through the cooling hole, the end of the cooling pipe located in the cabinet is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the cooling pipe is fixedly connected to the cold air component, The side of the cold air component away from the connecting pipe passes through the bottom plate and extends to the inside of the water collecting component, and the outer side surface of the cold air component is fixedly connected to the inner side surface of the bottom plate. When the cold air component is started, the clean water inside the water collecting component is drawn into the cold air component, and the outside air is drawn into the cold air component. Finally, the cold air component blows out humid cold air, and then the humid cold air enters the connecting pipe, and then enters the cooling pipe, and finally enters the cabinet through the cooling hole, cooling the cabinet and providing a low-temperature environment for the cowpea seedlings. The cooling pipes that are serpentine and surrounding the outside of several placement racks can evenly cool the areas around the several placement racks, and the serpentine distribution of the cooling pipes can provide a longer circulation path for the cold air, thereby achieving a better cooling effect.

[0014] Furthermore, the cold air component includes a pump body, which is fixedly connected to the end of the connecting pipe away from the cooling pipe, the pump body is fixedly connected to the side of the cabinet away from the bottom plate, the end of the pump body away from the connecting pipe is fixedly connected to the cold air pipe, the end of the cold air pipe away from the pump body is fixedly connected to the cold air fan, the cold air fan is fixedly connected to the side of the bottom plate close to the cabinet, the side of the cold air fan away from the cold air pipe is fixedly connected to the water inlet pipe, the end of the water inlet pipe away from the cold air fan passes through the bottom plate and extends to the inside of the water collection component, the outer side surface of the water inlet pipe is fixedly connected to the inner side surface of the bottom plate, and the cold air fan is started, and clean water enters the water inlet pipe from the water collection component. , and then enters the air cooler to wet the wet curtain of the air cooler. Under the negative pressure of the air cooler, the outside air passes through the moist wet curtain at high speed, and the water evaporates rapidly to absorb heat, which greatly reduces the air temperature. The low-temperature air is transported to the pump body through the cold air pipe. The pump body sends the cold air evenly into the cabinet along the connecting pipe and the cooling pipe through pressurization. After the moist cold air contacts the seedlings in the pot, the water vapor quickly condenses into fine water droplets on the surface of the leaves of the seedlings in the pot, simulating the effect of natural morning dew. The water droplets slide to the placement rack under the action of gravity, and finally re-enter the water collection component to form a circulation system of water replenishment, evaporation, condensation, and recycling, which not only ensures the low temperature and high humidity environment required for hardening the seedlings, but also avoids waste of water resources.

[0015] Furthermore, a protective cover is fixedly connected to the side of the air cooler away from the base plate, and the protective cover is fixedly connected to the air inlet pipe of the air cooler. A dustproof plate is fixedly connected to the side of the protective cover away from the air cooler. The outside air enters the air cooler through the air inlet pipe of the air cooler, and then passes through the wet curtain of the air cooler. The moisture evaporates rapidly and absorbs heat, which greatly reduces the air temperature.

[0016] Furthermore, the side of the dustproof plate close to the bottom plate is rotatably connected to a fan blade through a rotating rod, and the fan blade is rotatably connected to the inner side of the shield. There are holes on the surface of the shield and the dustproof plate. Air enters the air cooler and then drives the fan blade to rotate. The fan blade drives the gas flow, thereby using the air intake of the air cooler to cool the outside of the air cooler.

[0017] Furthermore, the water collection component includes a water tank, the inner side surface of the water tank is fixedly connected to the bottom plate, and the water tank is arranged on the side of the bottom plate away from the cabinet body, and a partition is fixedly connected to the bottom of the inner side surface of the water tank, and there is a gap between the side of the partition away from the water tank and the bottom plate. The partition separates the cavity surrounded by the water tank and the bottom plate, ensuring that clean water enters the water inlet pipe through the top of the partition while preventing impurities such as mud from entering the water inlet pipe.

[0018] Furthermore, a trough plate is fixedly connected to the top of the bottom plate, and the side of the trough plate away from the bottom plate is set to an arc shape, and the trough plate is arranged inside the cabinet, and the trough plate is fixedly connected to the inner side of the cabinet. A middle seam is opened on the side of the trough plate away from the bottom plate, and the middle seam passes through the bottom plate. Condensed water droplets and dirt fall to the top of the trough plate, and then enter the middle seam along the curved surface, and finally enter the inside of the water tank through the middle seam. The curved trough plate surface can ensure that water droplets and dirt enter the middle seam under the action of gravity.

[0019] Furthermore, a blowing pipe is fixedly connected to the surface of the cooling pipe, and there are several blowing pipes, and the blowing pipes are symmetrically arranged on both sides of the middle seam. The side of the blowing pipe away from the cooling pipe is fixedly connected to the curved surface of the trough plate. The cold air enters the blowing pipe through the cooling pipe and then blows the curved surface of the trough plate. The high-speed airflow will form a wall-attaching effect along the curved surface, so that the cold air evenly covers the entire surface of the trough plate, thereby better blowing water droplets, dirt, etc. into the middle seam, and preventing dirt, water droplets, etc. from adhering to the surface of the trough plate.

[0020] Furthermore, the supporting assembly includes a placement hole, the placement hole is opened on the surface of the placement rack, and the placement holes are evenly distributed on the surface of the placement rack. The inner side surface of the placement hole is fixedly connected with a rubber plate, and the rubber plate is bent toward the side close to the bottom plate, and the rubber plate is evenly distributed along the inner side surface of the placement hole. The side of the placement rack close to the bottom plate is fixedly connected with a rope body, and the rope body is evenly distributed along the circumference of the placement hole, and the sides of the rope bodies away from the placement rack are fixedly connected to each other, and the cymbal seedling is placed inside the placement hole. The seedlings in the pots squeeze the rope body, thereby completing the placement of the seedlings in the pots. The elastic rubber plate can limit the seedlings in pots of different diameters to avoid damage to the seedlings when moving the placement rack. The rope body can absorb clean water and then gather it at the junction of several rope bodies. Under the action of gravity, the water forms water droplets at the junction of several rope bodies, and then drips onto the seedlings in the pots below to achieve irrigation. The excess water continues to penetrate downward along the rope body, and finally flows into the sink through the trough plate at the bottom of the placement rack, avoiding the risk of root rot caused by accumulated water soaking the roots of the seedlings, and completing the recycling of water resources at the same time.

[0021] Furthermore, a cone is provided directly below the placement hole, the inner side of the cone is fixedly connected to the surface of the rope body, a dropper is fixedly connected to the side of the cone away from the rope body, and the dropper is controlled by a valve, the cone is a funnel-shaped structure that is wide at the top and narrow at the bottom, and its wide top is tightly connected to the rope body, which can quickly collect moisture transmitted from the rope body, and then efficiently drain the moisture to the dropper at the bottom of the cone, and cooperate with the adjustable valve to accurately control the dripping speed and dripping amount according to the growth stage and water demand of the seedlings in the pot, which not only avoids water waste, but also prevents the roots of the seedlings in the pot from lack of oxygen and rot due to excessive water.

[0022] The present invention has the beneficial effects:

[0023] 1. The present invention provides a seedling hardening mechanism, and the cooling component blows out low-temperature and humid air. The low-temperature air simulates the low-temperature environment after transplanting, and then gradually lowers the ambient temperature to allow the seedlings to adapt to the low-temperature environment, thereby improving the cold resistance of the seedlings and enabling them to better adapt to the external low-temperature conditions after transplanting.

After the humid air contacts the seedlings, it condenses on the surface of their leaves, simulating the morning dew environment to obtain a more realistic external environment. It can not only replenish appropriate amount of water for the seedlings, but also further enhance the low-temperature adaptation effect by absorbing heat through water vapor evaporation. The condensed excess water droplets gradually drip along the layered placement racks, and finally enter the water collection component at the bottom of the cabinet, and then enter the cooling component, and are reused by the cooling component, while discharging excess water and realizing water circulation.

[0024] 2. The present invention sets a cooling component, and moist cold air enters the connecting pipe, then enters the cooling pipe, and finally enters the cabinet through the cooling hole, thereby cooling the cabinet and providing a low-temperature environment for the cowpea seedlings. The cooling pipes arranged in a serpentine shape and surrounding the outside of several placement racks can evenly cool the areas around the several placement racks, and the serpentine distribution of the cooling pipes can provide a longer circulation path for the cold air, thereby achieving a better cooling effect.

[0025] 3. The present invention sets a cold air component. After the moist cold air contacts the seedlings in the pot, the water vapor quickly condenses into fine water droplets on the surface of the leaves of the seedlings in the pot, simulating the effect of natural morning dew. The water droplets slide to the placement rack under the action of gravity and finally re-enter the water collection component to form a circulation system of water replenishment, evaporation, condensation and recycling, which not only ensures the low temperature and high humidity environment required for hardening the seedlings, but also avoids the waste of water resources. The air enters the air cooler, which then drives the fan blades to rotate, and the fan blades drive the gas flow, so that the air intake of the air cooler is used to cool the outside of the air cooler.

The high-speed airflow will form a wall-attaching effect along the arc-shaped surface, so that the cold air evenly covers the entire trough plate surface, thereby better blowing water droplets, soil, etc. into the middle seam, and preventing soil, water droplets, etc. from adhering to the trough plate surface.

[0027] 5. The present invention sets a supporting component, and the elastic rubber plate can limit the seedlings in pots of different diameters to avoid damage to the seedlings when the placement rack is moved. The rope body can absorb clean water and then gather it at the junction of several rope bodies. Under the action of gravity, the water forms water droplets at the junction of several rope bodies, and then drips onto the seedlings in the pots below to achieve irrigation. The excess water continues to penetrate downward along the rope body and finally flows into the water tank through the groove plate at the bottom of the placement rack, avoiding the risk of root rot caused by accumulated water soaking the roots of the seedlings, and at the same time completing the recycling of water resources.

A dropper 425 is fixedly connected to the side of the cone 424 away from the rope body 423, and the dropper 425 is controlled by a valve. The cone 424 has a funnel-shaped structure that is wide at the top and narrow at the bottom. Its wide top is tightly connected to the rope body 423, which can quickly collect water transmitted from the rope body 423. The cone 424 then efficiently drains the water to the dropper 425 at the bottom. In combination with the adjustable valve, the dripping speed and dripping amount can be accurately controlled according to the growth stage and water requirement of the seedlings in the pot, which not only avoids water waste, but also prevents the roots of the seedlings from lacking oxygen and rotting due to excessive water.

[0057] When in use, open the cabinet door 3, take out the placement rack 41, and at the same time take out the supporting assembly 42, then place the cymbal seedling inside the placement hole 421, and the pot seedling squeezes the rope body 423, thereby completing the placement of the pot seedling, fill several supporting assemblies 42 in turn, then insert the placement rack 41 back, then take out another placement rack 41, and repeat the above steps, fill all the supporting assemblies 42, start the air cooler 4343, and clean water enters the water inlet pipe 4344 from the water collection assembly 44, and then enters the air cooler 4343, wetting the air cooler The outside air enters the air cooler 4343 through the air inlet pipe of the air cooler 4343, passes through the wet wet curtain at high speed, and the water evaporates quickly to absorb heat, which greatly reduces the air temperature. The air enters the air cooler 4343, and then drives the fan blades 4347 to rotate. The fan blades 4347 drive the air flow to cool the outside of the air cooler 4343. At the same time, the low-temperature air is transported to the pump body 4341 through the cold air pipe 4342. The pump body 4341 pressurizes the cold air along the connecting pipe 433, the cooling pipe 431, and the cooling hole 432. The air is evenly sent into the cabinet 2 to cool the cabinet 2, providing a low-temperature environment for the cowpea seedlings. After the moist cold air contacts the seedlings, the water vapor quickly condenses into fine water droplets on the surface of the seedling leaves, simulating the effect of natural morning dew. The rope body 423 can absorb the clean water and then gather at the junction of several rope bodies 423. Under the action of gravity, the water forms water droplets at the junction of several rope bodies 423, and then drips onto the seedlings below to irrigate. The excess water continues to penetrate downward along the rope body 423 and finally passes through the groove plate at the bottom of the placement rack 41. 443 flows into the water trough 441, and the condensed water droplets and mud fall to the top of the trough plate 443, then enter the middle gap 444 along the curved surface, and finally enter the inside of the water trough 441 through the middle gap 444. The cold air enters the blowing pipe 445 through the cooling pipe 431, and then blows the curved surface of the trough plate 443. The high-speed airflow will form a wall-attaching effect along the curved surface, so that the cold air evenly covers the entire surface of the trough plate 443, and blows the water droplets, mud, etc. into the middle gap 444, forming a circulation system of water replenishment, evaporation, condensation, and recovery.
