[0029] In order to make the above-mentioned purpose, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other manners different from those described herein without departing from the scope of the present application, and those skilled in the art can make similar generalizations without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0031] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments. EMBODIMENT

[0032] REFERENCE Figure 1For the first embodiment of the utility model, the embodiment provides a hot air box, comprising, drying box 100, with drying box 100 inside the first hot air port 101, be located in the filter screen 103 of drying box 100 inside.

[0033] Be located in the filter screen 103 of drying box 100 inside.

[0034] Wherein, the filter screen 103 is attached in the drying box 100 inner wall, wherein, the first hot air port 101 communicates drying box 100 inside, and the connecting port is between the filter screen 103 and the bottom of drying box 100, the advantage of such design is that the seed to be dried is placed above the filter screen 103, to prevent the seed from sliding and blocking the hot air port, second, this design can also utilize the attribute of hot air upward movement, from bottom to top drying seed.

[0035] At the same time, the inductor 102 is arranged at different positions of the drying box 100, which can detect the temperature and humidity of multiple positions of the drying box 100, and the hot air moves upward from the bottom, then carries away the moisture, and the inductors 102 at different positions can detect the temperature and humidity of each region in the drying box 100. When the temperature and humidity of all inductors 102 meet the standard, the internal seed is completely dried, at this time, the first hot air port 101 can be directly closed. The first hot air port 101 is connected to the hot air fan to provide hot air for seed drying.

[0036] In summary, the seed is placed in the drying box 100, the filter screen 103 holds up the seed, then the first hot air port 101 is used to deliver hot air to the drying box 100, the hot air is delivered from below the filter screen 103 into the bottom of the drying box 100, and the hot air starts to rise upward; when the temperature and humidity of the inductor 102 meet the standard, stop the hot air delivery of the first hot air port 101. Embodiment

[0037] Reference Figures 1-5 For the second embodiment of the utility model, the inductor 102 comprises a first temperature and humidity sensor 102a, a second temperature and humidity sensor 102b and a third temperature and humidity sensor 102c, and the first temperature and humidity sensor 102a is located at the bottom of the drying box 100, and the third temperature and humidity sensor 102c is located at the top of the drying box 100.

[0038] The inductor 102 extends from the layer of the filter screen 103 to the layer of the top end inside the drying box 100, wherein the inductor 102 uniformly distributes three temperature and humidity sensors, the first temperature and humidity sensor 102a, the second temperature and humidity sensor 102b and the third temperature and humidity sensor 102c; wherein the temperature and humidity sensors all adopt the commercially available devices and can be used for collecting temperature and humidity; the inductor 102 is arranged at the four corners and the center position of the drying box 100, which is equivalent to arranging the temperature and humidity sensors at the four corners and the center position of the drying box 100, equivalent to arranging five first temperature and humidity sensors 102a at the layer of the filter screen 103, arranging five second temperature and humidity sensors 102b at the layer between the filter screen 103 and the top inside the drying box 100, and arranging five third temperature and humidity sensors 102c at the position of the top inside the drying box 100, so that the drying box 100 is divided into three layers, the seed temperature and humidity in different layers can be monitored, and the seed drying degree inside the drying box 100 can be monitored.

[0039] The drying box 100 comprises a first surface 100a and a second surface 100b, and there are three channels between the drying box 100 and the first hot air outlet 101, one of which is located between the filter screen 103 and the first surface 100a, and a valve is arranged in each of the three channels.

[0040] The bottom surface inside the drying box 100 is the first surface 100a, and the upper surface inside the drying box 100 is the second surface 100b, and a channel with a valve is arranged between each layer of temperature and humidity sensors; a channel is arranged between the filter screen 103 and the bottom of the drying box 100, a channel is arranged between the first temperature and humidity sensor 102a and the second temperature and humidity sensor 102b, and a channel is arranged between the second temperature and humidity sensor 102b and the third temperature and humidity sensor 102c, and a switchable valve is arranged between each channel, so that the corresponding valve can be opened or closed according to the area temperature and humidity detected by the internal temperature and humidity sensor, the corresponding area hot air conveying amount is adjusted and controlled, and the damage rate in the seed drying process is reduced.

[0041] Each channel is connected with an air outlet pipe 104, and the air outlet pipe 104 extends to the inside of the drying box 100.

[0042] Each channel is connected with an air outlet pipe 104 at the opening of the inside of the drying box 100, and the air outlet pipe 104 is a sleeve structure with one end closed, and the opening end is in communication with the channel; the outer wall of the air outlet pipe 104 is uniformly provided with a through hole, and the through hole communicates the inside of the air outlet pipe 104 with the outside; when the hot air is input from the first hot air outlet 101, then enters the air outlet pipe 104 through the channel, and then is discharged from the air outlet pipe 104 through the through hole and enters the inside of the drying box 100, so that the hot air can be blown more uniformly from the channel to the side of the drying box 100 away from the channel.

[0043] The air outlet pipe 104 corresponding to the channel is provided with at least one.

[0044] It should be noted that the open end of the air outlet pipe 104 is inserted into the channel, at which time the channel can be blocked, and then different air outlet pipes 104 are controlled by a single valve; a plurality of air outlet pipes 104 are arranged in the direction of the bottom plane of the drying box 100 at the same channel, which has the advantage that the hot air can be blown horizontally and upward, so that the hot air is more evenly distributed, and the inductors 102 at the four corners and the center position can better monitor the hot air volume in the drying box 100. According to the temperature and humidity conditions at different positions, the valves corresponding to different air outlet pipes 104 can be adjusted to reduce the air volume at the corresponding position to prevent the temperature from being too high and the seeds from being dried too much, which can damage the finished product.

[0045] The air outlet pipe 104 is a non-linear pipe.

[0046] As shown in Figure 5 The air outlet pipe 104 is divided into a plurality of regions, and the width between each region is the same, which has the advantage that the internal air volume will reach saturation under the condition that one end port is closed, and the air volume at each position of the air outlet pipe 104 will be roughly the same, ensuring that the air volume in a plane is uniform and the air volume received by the seeds is as uniform as possible.

[0047] The drying box 100 is provided with an air outlet 106 on the side.

[0048] The air outlet 106 is the air outlet of the drying box 100, and the air outlet 106 is arranged on the side, i.e., other than the first face 100a and the second face 100b, and the air outlet 106 is arranged at the middle position of the first face 100a and the second face 100b, which has the advantage that the drying box 100 is built-in with three-layer air outlet pipes 104, and the air outlet pipes 104 in the middle layer and the upper and lower air outlet pipes 104 will form a gas flow collision, but because the air outlet 106 is at the middle position, the gas will escape in the direction of the air outlet 106; which has the advantage that when in use, the air volume of the air outlet pipe 104 in the middle can be preferentially controlled by the valve to be larger, and the air volume in the middle position is larger, so that the collision position is closer to the upper and lower surfaces of the drying box 100, and when the second temperature and humidity sensor 102b detects that the seeds in the middle layer are basically qualified, the air volume of the air outlet pipe 104 in the middle layer can be closed or reduced, and the air volume of the upper and lower air outlet pipes 104 can be increased. Because the air outlet 106 is at the middle position, the colliding air will escape to the air outlet 106, at which time, as long as the temperature and humidity sensor indicators in the drying box 100 meet the standards, the drying is completed, and this scheme greatly reduces the problem of insufficient yield rate caused by the traditional drying box 100. Embodiment

[0049] Referring to Figures 1-7 For the third embodiment of the present application, the embodiment further provides a seed air drying system. The system comprises a hot air tower 200 connected with a first hot air outlet 101 through a main air duct 201.

[0050] The hot air box is connected with the main air duct 201 through a branch air pipe 202, and the branch air pipe 202 is communicated with the first hot air outlet 101.

[0051] The branch air pipe 202 is internally provided with a valve.

[0052] As shown in Figure 6 The upper part of the hot air tower 200 is connected with the main air duct 201, the main air duct 201 is connected with the first hot air outlet 101, the hot air outlet 101 is communicated with the passage through the branch air pipe 202, and the air volume of each drying box 100 is controlled by each branch air pipe 202, and a valve capable of controlling the switch is arranged in the interior of each branch air pipe 202. The advantage of such design is that the air volume switch of each drying box 100 can be controlled, multiple drying boxes 100 can be simultaneously air dried, and they do not affect each other.

[0053] At the same time, the air pipe is arranged as an annular overhead pipe close to the wall surface of the factory building, the space of the factory building is fully utilized, the air pipe is covered with rock wool, polyurethane foam and other thermal insulation materials, the heat loss of the hot air in the conveying process is reduced, and the energy utilization efficiency is improved. The effect of saving space and reducing heat loss is achieved.
