Description

Technical Field

[0001] The invention belongs to the technical field of seed cultivation, in particular to a seed germination chamber. Background Art

[0002] The seed germination room is a special facility used in modern agriculture to regulate the seed germination environment. Its core function is to provide suitable germination conditions for seeds by precisely controlling indoor parameters such as temperature, humidity, and ventilation, thereby shortening the germination cycle, improving the germination rate and uniformity of seedlings. It is widely used in the seedling cultivation of vegetables, grains, flowers and other crops. During seed germination, seeds are typically evenly sown in seedling trays filled with a substrate. These trays are then stacked layer by layer within the germination room to improve space utilization and accommodate large-scale seedling production. The germination process involves sowing treated seeds (such as soaked and sterilized seeds) into the substrate in the seedling trays. The trays are then stacked on a rack at a predetermined spacing. After closing the germination room, hot air is introduced into the room through an air duct system to maintain a suitable temperature of 28-40°C. A humidifier delivers water mist to maintain a relative humidity of 80-90%. Ventilation equipment is also used to circulate air, ensuring that the seeds germinate in a constant temperature and humidity environment.

[0003] However, the seedling trays are stacked layer by layer in the germination room, thus forming a "three-dimensional barrier". Since the stacked seedling trays form a "three-dimensional barrier", the temperature and humidity distribution in the germination room is very likely to be uneven.

[0004] From a vertical perspective, the upper seedling tray is close to the air supply outlet of hot air and water mist, and the heat density is low and tends to gather upward, so the temperature is often high and the humidity is low; the middle seedling tray is less affected by the upper and lower layers, and the temperature and humidity are relatively close to the set values; the lower seedling tray has weak airflow penetration ability, which makes it difficult for hot air to reach it, so the temperature is low. At the same time, water mist tends to accumulate at the bottom due to gravity sedimentation, resulting in high humidity and even water accumulation in the substrate.

[0005] Due to the inconsistent temperature and humidity at different heights, the germination time of seeds at different heights is easily deviated, which will also affect the germination rate of seeds at different heights, resulting in differences in the growth of seeds germinated in the same batch. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the present invention proposes a seed germination chamber.

[0015] The beneficial effects of the present invention are as follows: 1. The seed germination chamber described in the present invention transmits hot air and water mist through a supporting tube, and allows the hot air and water mist to directly enter the seedling tray through an arc groove, so that the hot air and water mist directly act on the matrix and seeds of the seedling tray, thereby avoiding the formation of a "three-dimensional barrier" by the seedling trays stacked in layers, which causes the hot air and water mist to be unable to be evenly distributed in different seedling trays, resulting in inconsistent temperature and humidity in seedling trays at different heights, resulting in deviations in the germination time of seeds at different heights, and at the same time affecting the germination rate of seeds at different heights, resulting in differences in the growth of seeds germinated in the same batch.

[0016] 2. The seed germination chamber described in the present invention first introduces hot air and water mist into the supporting tube and pushes the sliding plate to move upward. The upward sliding plate will drive the annular tube to move upward through the pushing block, and make all the ventilation grooves and all the air outlet grooves coincide with each other at the same time. When the ventilation grooves and the air outlet grooves coincide with each other, the gas in the supporting tube can enter the relative seedling trays at the same time, thereby avoiding the situation where the hot air and water mist in the supporting tube enter different seedling trays from bottom to top in sequence, which will cause time difference when seedling trays at different heights come into contact with hot air and water mist, resulting in obvious differences in the germination time of seeds at different heights.

[0017] 3. A seed germination chamber described in the present invention has an air duct provided on the seedling tray that passes through the arc-shaped groove that is fitted with the support tube and is connected to the air outlet groove. When the hot air and water mist flow out from the air outlet groove, part of the hot air and water mist will flow in the air duct and then flow out through the evenly arranged air holes. Since the air holes are distributed at different positions of the inner circle of the seedling tray, the hot air and water mist flowing out from the air holes will act on different positions of the seedling tray, thereby flowing to different positions of the seedling tray more evenly, so that the substrate and seeds in the seedling tray can be more comprehensively contacted, and the hot air and water mist can be prevented from directly flowing out from another arc-shaped groove after entering the seedling tray, thereby causing dead corners for the seeds in the seedling tray and making it impossible to fully germinate the seeds.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 12 As shown, a seed germination chamber according to the present invention, as an embodiment of the present invention, comprises a germination chamber 1; a chamber door is installed on the germination chamber 1; heat pump units 11 are fixedly installed on both sides of the chamber door; a transmission pipe 12 is connected to the heat pump unit 11, and the transmission pipe 12 extends into the germination chamber 1; a humidifier 13 is installed on one side of the heat pump unit 11, and the output end of the humidifier 13 is connected to the transmission pipe 12; The germination chamber 1 is equipped with multiple evenly arranged stacking trays 2; an annular air silo 21 is fixedly installed inside the stacking tray 2, and the transmission pipe 12 extends into the annular air silo 21; adjacent annular air silos 21 are connected through connecting pipes; The top of each stacking tray 2 is fixedly connected to a support tube 22, and the top of the support tube 22 is fixedly connected to the top of the germination chamber 1 and communicated with the outside; the bottom of the support tube 22 extends into the annular air chamber 21; The outer surface of the support tube 22 is provided with a plurality of evenly arranged air groove groups; each of the air groove groups includes four air outlet grooves 23; It also includes a supporting seedling tray 3; the seedling tray 3 has two arc-shaped grooves 31 at two opposite corners, and the arc-shaped grooves 31 are connected to the inner cavity of the seedling tray 3; the arc-shaped grooves 31 are a quarter circle; The seedling trays 3 are placed on the stacking trays 2 and stacked on each other, and the stacked seedling trays 3 form a seedling tray stack; the outer ring of the support tube 22 is provided with four groups of germination tray stacks; One of the arc-shaped grooves 31 on the seedling trays 3 in the four seedling tray stacks fits in with the support tube 22; the seedling trays 3 on the adjacent seedling tray stacks fit in with each other; The number of layers of the seedling tray 3 is the same as the number of the air groove groups, and one of the arc-shaped grooves 31 on the seedling tray 3 corresponds to the air outlet groove 23 one by one; In this embodiment, a retaining ring is fixedly connected to one side of the support tube 22 extending into the annular air chamber 21; a sliding plate 24 slides above the retaining ring; An annular groove is formed inside the support cylinder 22, and an air outlet groove 23 penetrates the annular groove; an annular cylinder 25 slides inside the annular groove; The inner wall of the annular cylinder 25 is provided with a plurality of through-groove groups, and the number of the through-groove groups is the same as the number of the air groove groups; each of the through-groove groups includes four air vents 26; in the initial state, the air vents 26 and the air outlet grooves 23 are arranged alternately; The top of the annular cylinder 25 is located in the inner wall of the support cylinder 22 and has two sliding grooves 27, which are connected to the annular groove; the top of the annular cylinder 25 is fixedly connected to a push block 28, which slides in the sliding groove 27 and extends to the inner ring of the support cylinder 22.

[0023] During implementation, when the seeds are germinated, the seeds are first sown in the seedling tray 3 filled with the substrate, and then the seedling tray 3 is transferred to the stacking tray 2 in sequence, and the arc groove 31 opened on the seedling tray 3 is fitted with the surface of the support tube 22, and the arc groove 31 is matched with the air outlet groove 23 on the support tube 22, and then the seedling tray 3 is stacked layer by layer to form four seedling tray stacks, and the number of layers of the four seedling tray stacks is the same as the number of air groove groups. When the seedling tray 3 is stacked on all the stacking trays 2, the germination work can be carried out; during germination, the heat pump unit 11 is started, and the heat pump unit 11 will introduce the hot air into the germination chamber 1 through the transmission pipe 12, and at the same time, the humidifier 13 is controlled to work, and the water mist generated by the humidifier 13 will enter the transmission pipe 12 and be brought into the germination chamber 1 together with the hot air in the transmission pipe 12; Specifically, since the transmission pipe 12 is connected to the annular air chamber 21, the hot air and water mist will first enter the annular air chamber 21, and since the support tube 22 is located in the annular air chamber 21 and is connected, the hot air and water mist will gradually enter the support tube 22. Since the ventilation grooves 26 on the annular tube 25 are staggered with the air outlet grooves 23 in the initial state, the air outlet grooves 23 can be blocked, and the hot air and water mist cannot flow out through the air outlet grooves 23. As the hot air entering the support tube 22 gradually increases, it will gradually push the sliding plate 24 on the support tube 25. The interior of the support cylinder 22 gradually moves upward. When the sliding plate 24 moves upward to above the uppermost air outlet groove 23, it will contact the push block 28 and push the push block 28 to gradually move upward in the slide groove 27. The upward push block 28 will drive the annular cylinder 25 to move upward. During the upward movement of the annular cylinder 25, the ventilation groove 26 on the annular cylinder 25 will move upward and gradually overlap with the air outlet groove 23. When the ventilation groove 26 overlaps with the air outlet groove 23, the hot air and water mist inside the support cylinder 22 will flow out through the air outlet groove 23, thereby accelerating the germination of the seeds. More specifically, since the air outlet groove 23 and the arc groove 31 correspond to each other, the hot air and water mist flowing out of the air outlet groove 23 will first enter the arc groove 31, and the arc groove 31 is connected to the inner cavity of the seedling tray 3, so that the hot air and water mist will enter the seedling tray 3, thereby making the hot air and water mist directly act on the substrate and seeds of the seedling tray 3. As the hot air and water mist entering the seedling tray 3 gradually increase, the hot air and water mist in the seedling tray 3 will flow out from the arc groove 31 on the other side of the seedling tray 3, and then flow into the germination chamber 1; When it is not necessary to introduce hot air and water mist into the germination chamber 1, the heat pump unit 11 and the humidifier 13 are turned off. At this time, hot air no longer enters the annular air chamber 21, so the sliding plate 24 no longer pushes the push block 28 upward, and the sliding plate 24 and the annular cylinder 25 slide downward under their own gravity and return to their initial state. When it is necessary to introduce hot air and water mist into the germination chamber 1 again, the above operation is repeated; In general, by utilizing the support tube 22 to transmit hot air and water mist, and making the hot air and water mist directly enter the seedling tray 3 through the arc groove 31, the hot air and water mist can directly act on the matrix and seeds of the seedling tray 3, thereby avoiding the seedling trays 3 stacked layer by layer from forming a "three-dimensional barrier", which causes the hot air and water mist to be unable to be evenly distributed in different seedling trays 3, resulting in inconsistent temperature and humidity in seedling trays 3 at different heights, resulting in deviations in the germination time of seeds at different heights, and at the same time affecting the germination rate of seeds at different heights, resulting in differences in the growth of seeds germinated in the same batch; At the same time, by first introducing the hot air and water mist into the support tube 22 and pushing the sliding plate 24 upward, the upward sliding plate 24 will drive the annular tube 25 upward through the pushing block 28, and make all the ventilation grooves 26 coincide with all the air outlet grooves 23 at the same time. When the ventilation grooves 26 coincide with the air outlet grooves 23, the gas in the support tube 22 can enter the relative seedling tray 3 at the same time, thereby avoiding the hot air and water mist in the support tube 22 entering different seedling trays 3 from bottom to top in turn, which will cause time difference when the seedling trays 3 at different heights come into contact with the hot air and water mist, resulting in obvious differences in the germination time of seeds at different heights.

[0024] As an embodiment of the present invention; each of the seedling trays 3 is close to the side of the support tube 22, and two grooves 32 are provided on the surface of the seedling tray 3; An n-type plate 33 is provided between adjacent seedling trays 3, and the n-type plate 33 is engaged on two adjacent seedling trays 3 and located in the notch 32; the top of the n-type plate 33 located in the notch 32 is flush with the top of the seedling tray 3; In this embodiment, a rubber ring is fixedly connected to the side where the arc-shaped groove 31 contacts the support tube 22 , and the rubber ring is used to seal the gap between the arc-shaped groove 31 and the support tube 22 .

[0025] During implementation, when placing the seedling tray 3, after the four seedling trays 3 of each layer are placed, the n-type plate 33 is engaged on the side wall of the adjacent seedling tray 3, and the n-type plate 33 is engaged in the missing groove 32. In this process, the four seedling trays 3 of each layer can be connected and fixed. At the same time, since a support tube 22 is provided between the four seedling trays 3, the support tube 22 can limit the four connected seedling trays 3 to avoid the seedling tray 3 from tilting and collapsing due to the high number of layers. After the four seedling trays 3 of each layer are connected and fixed, the seedling tray 3 can be better fitted with the support tube 22, and since a sealing ring is provided on the arc groove 31 fitted with the support tube 22, the sealing effect of the arc groove 31 and the support tube 22 can be increased to avoid air leakage.

[0026] As an embodiment of the present invention; the four side walls of the seedling tray 3 are provided with air passages 34, and the air passages 34 are interconnected; the side walls of the seedling tray 3 are provided with evenly arranged air holes 35, and the air holes 35 are connected to the air passages 34; The air channel 34 passes through the arc-shaped groove 31 that fits the support tube 22 and is connected to the air outlet groove 23; In this embodiment, slide plates 36 are provided in the four side walls of the seedling tray 3, and the slide plates 36 slide in the air passage 34 via springs; The side of the slide 36 away from the air hole 35 is an inclined surface; the top of the slide 36 is provided with evenly arranged conical holes 37; the bottom of the seedling tray 3 is fixedly connected with evenly arranged insertion rods 38, and the insertion rods 38 correspond one to one with the conical holes 37 below; The slide plate 36 is fixedly connected to a push rod 39 on one side close to the air hole 35 via a connecting rod, and the push rod 39 is initially located in the air hole 35; In this embodiment, the push rod 39 is conical and blocks the air hole 35 .

[0027] During implementation, since the air duct 34 opened in the seedling tray 3 passes through the arc groove 31 that fits with the support tube 22 and is connected to the air outlet groove 23, when the hot air and water mist flow out of the air outlet groove 23, part of the hot air and water mist will flow in the air duct 34 and then flow out through the evenly arranged air holes 35. Since the air holes 35 are distributed at different positions of the inner circle of the seedling tray 3, the hot air and water mist flowing out from the air holes 35 will act on different positions of the seedling tray 3, thereby flowing to different positions of the seedling tray 3 more evenly, so that the substrate and seeds in the seedling tray 3 can be more comprehensively contacted, and the hot air and water mist are prevented from directly flowing out from another arc groove 31 after entering the seedling tray 3, thereby causing dead corners for the seeds in the seedling tray 3 and making it impossible to fully germinate the seeds; When the push rod 39 moves along with the slide 36, it will gradually extend from the air hole 35 and extend into the seedling tray 3. In this process, the substrate in the air hole 35 can be pushed out, preventing the substrate from clogging the air hole 35 and preventing hot air and water mist from being ejected. More specifically, since the push rod 39 is conical, when the hot air and water mist flow out through the air hole 35, the conical push rod 39 can guide the hot air and water mist, thereby expanding the range of the hot air and water mist outflow, so as to more comprehensively contact the substrate and intermediate.

[0028] As an embodiment of the present invention; the stacking tray 2 is provided with slideways 4 at the four corners, and the slideways 4 are opened on the bottom plate and the top plate of the germination chamber 1; the slideways 4 located on the bottom plate of the germination chamber 1 are installed with water outlet pipes, and the water outlet pipes extend to the outside; A vertical cylinder 41 slides in the upper and lower opposite slideways 4; the diameter of the vertical cylinder 41 is the same as the diameter of the arc-shaped groove 31 on the seedling tray 3; The vertical tube 41 is provided with uniformly arranged first slots 42 on one side facing the arc-shaped slot 31, and the first slots 42 correspond to the arc-shaped slots 31 one by one; uniformly arranged baffles 43 are fixedly connected to the vertical tube 41, and the baffles 43 are tilted downward to block the first slots 42; The vertical tube 41 is provided with evenly arranged second notches 44 on one side away from the arc-shaped groove 31 , and the second notches 44 are staggered with the first notches 42 ; A guide cylinder 48 is fixedly connected to the middle of the germination chamber 1, and a long groove 49 is opened on the outer ring of the guide cylinder 48; the guide cylinder 48 extends to the outside and is connected to the heat pump unit 11 through a conduit; In this embodiment, the top and bottom of the vertical cylinder 41 are fixedly connected to two sliders 45; the bottom of the slider 45 is rotatably connected to a roller 46; A limiting rod 47 is slidably mounted on the slider 45 .

[0029] During implementation, when the seedling tray 3 on the stacking tray 2 is placed, the vertical cylinder 41 is pushed to move, and the moving vertical cylinder 41 will slide in the slide 4 opened on the top plate and the bottom plate during germination through the slider 45 and the roller 46. When the vertical cylinder 41 is in contact with another arc groove 31 on the seedling tray 3, the seedling tray 3 corresponds to the first notch 42 opened on the vertical cylinder 41. Then the limiting rod 47 is inserted into the slider 45 and the limiting rod 47 is in contact with the bottom of the slide 4, so that the slider 45 can be fixed, and the vertical cylinder 41 can be indirectly fixed. At this time, the vertical cylinder 41 can protect the outside of the seedling tray 3, further preventing the seedling tray 3 from tilting and collapsing. The hot air will be guided by the baffle 43 and continue to flow, and then flow out through the second notch 44 at different heights. The water droplets formed by the water mist intercepted by the baffle 43 will flow downward and flow into the slide 4 below. Since an outlet pipe is installed in the slide 4 below, the water in the slide 4 will flow out through the outlet pipe and then be stored. In this process, the water droplets formed by the water mist can be prevented from falling into the germination chamber 1, causing water accumulation in the germination chamber 1, thereby easily eroding the bottom plate of the germination chamber 1. At the same time, water can be recycled to reduce water waste. More specifically, since the hot air flows out from different second notches 44 respectively, the outflowing hot air will be distributed at different height positions in the germination chamber 1, thereby reducing the temperature difference at different heights in the germination chamber 1. When the air in the germination chamber 1 needs to be circulated, the gas in the germination chamber 1 can be discharged through the long groove 49 opened on the guide cylinder 48 and re-introduced into the heat pump unit 11 for circulation.
