Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, in particular to a multi-layer germination box. Background Art

[0002] In order to accelerate the promotion and application of high-quality varieties of grain crops and advanced applicable technologies, and to accelerate the development of the grain industry, it is necessary to carry out trials and demonstrations of the introduction of new rice varieties. Among them, germination of rice seeds is an important part of the introduction of new rice varieties. The traditional way of germinating rice is mainly to soak the rice in water and then germinate naturally. This germination method is inefficient, time-consuming, has a low survival rate, and the germination is uneven, which is not conducive to the introduction of new rice varieties.

[0003] Therefore, in order to speed up the introduction and trial of new rice varieties, steam germination is generally adopted. For example, the Chinese utility model patent with publication number CN205105575U discloses a rice steam germination device, including a shell and a germination vehicle, the germination vehicle includes a multi-layer air-permeable partition... The two ends of the shell are respectively a feed port end and an air outlet end, the feed port end is hinged with a cover plate, and a steam distribution plate is installed, and a plurality of air jet holes are installed on the steam distribution plate... There is a condensate outlet at the bottom of the shell.

[0004] The existing steam germination machine, through the design of multi-layer breathable baffles in the germination vehicle, has significantly increased the amount of rice seeds that can be germinated in a single time. However, since the germination of rice seeds has requirements for temperature, humidity and oxygen concentration, the existing steam germination machine also has certain defects:

[0005] 1) The steam port set on one side will make the steam contact with the rice seeds uneven, forming a large temperature gradient, so that the rice seeds in different positions are exposed to different temperatures, resulting in uneven germination and uneven germination, which seriously affects the germination quality of the rice seeds;

[0006] 2) After the steam condenses, it will drip from the upper breathable partition to the lower breathable partition, causing a large difference in the humidity of the rice seeds spread on the upper and lower breathable partitions, which is not conducive to the humidity control in the germination box. Utility Model Content

[0007] In view of the defects in the prior art, the utility model provides a multi-layer germination box to at least solve the technical problem that the rice seeds at different positions in the existing steam germination device are in uneven contact with the steam, thus affecting the germination quality.

[0027] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] See also Figure 1-6 The utility model provides a multi-layer germination box, including a box body 1, a germination cart 2, a germination frame 3 and a steam coil 7. There are at least two steam coils 7 evenly spaced along the height direction of the box body 1 inside the box body 1, and a box door 11 is provided on one side of the box body 1 to facilitate taking out or placing the germination cart 2. Among them, the coil can be in a variety of forms such as U-shaped, S-shaped, spiral line type, etc., so as to cover the germination frame 3 as much as possible. The box body 1 is also installed with pressure, temperature, humidity, oxygen concentration and other detection modules and pressure relief safety devices according to industry standards. There are at least two germination frames 3 and they are stacked on the top surface of the germination cart 2. The bottom surface is provided with a plurality of air holes, and there are at least spaces for accommodating the steam coils 7 between the adjacent two germination frames 3 and between the top germination frame 3 and the top of the box body 1, so that there is a steam coil 7 above each germination frame 3 when the germination cart 2 is pushed in from outside the box. The two ends of the steam coil 7 are respectively connected to the steam main pipe 5 and the steam recovery pipe 6, and a plurality of steam outlet holes are opened at the bottom and / or the peripheral side of the bottom of the coil for supplying steam into the corresponding germination frame 3 below, that is, the steam can be blown straight downward or obliquely downward in the same direction or multiple directions.

[0029] Generally, the steam main pipe 5 is mainly used to distribute the steam obtained from the external steam source to each steam coil 7. Therefore, the surface of the steam main pipe 5 is also provided with a steam access port for communicating with the external steam source. In particular, since the germination of rice seeds also requires a certain amount of oxygen or ventilation, the oxygen channel or ventilation channel formed by opening the box door 11 is slightly insufficient, so a ventilation access port connected to the external oxygen source can also be reserved on the steam main pipe 5 to accelerate the air flow by blowing. Obviously, a valve such as an angle valve is provided between each steam coil 7 and the steam main pipe 5 to independently control the ventilation volume of each steam coil 7, so the number of germination frames can be increased or decreased according to the amount of rice seeds for a single germination.

[0030] As a further improvement of the above scheme, the multi-layer germination box further includes a water guide plate / disc 4, the number of which corresponds to the germination frame 3, and is arranged below the corresponding germination frame 3 to receive the condensed water dripping from the upper air holes and guide the condensed water to a specified position / direction in the box body 1. Generally, please refer to Figure 2-3, the water guide plate / disc 4 can be tilted toward the specified position / direction in the box to achieve the drainage effect, and in order to enhance the drainage effect, one or more folding grooves can be set on the water guide plate / disc 4 through sheet metal processing. Preferably, please refer to Figure 4-5 The multi-layer germination box also includes a water collecting trough 9, which is arranged at the bottom of the inner side of the box body 1 and is adjacent to the germination vehicle 2, and a drainage port penetrating the box body 1 is provided at the bottom thereof.

[0031] As a further improvement to the above scheme, please refer to Figure 4-5 The multi-layer germination box also includes a partition plate 8, which is arranged in the box body 1 and sandwiched between the germination vehicle 2 and the water collecting tank 9. The surface of the partition plate 8 is provided with water guide holes 81 corresponding to the water guide plate / disc 4, so that the water guide plate / disc 4 can guide the condensed water to flow into the water collecting tank 9 through the water guide holes 81. The purpose of setting the partition plate 8 is, on the one hand, to divide the interior of the germination box into a steam generation area and a wastewater collection area, and to prevent the steam from escaping to the water collecting tank 9 and being wasted; on the other hand, the partition plate 8 is also used as a support plate for the steam coil 7, and a support rod extending toward the germination vehicle and fixedly connected to the steam coil 7 can be welded on the partition plate 8 for lifting the steam coil 7, such as an angle steel.

[0032] Generally, see Figure 3 In order to ensure that there is space between two adjacent germination frames 3 for accommodating the steam coil 7, four legs are usually provided on the periphery of the germination frame 3. In order to prevent the four legs of the germination frame 3 from interfering with the steam coil 7 when the germination vehicle 2 enters, please refer to Figure 2 The multi-layer germination box also includes a guide groove 12 arranged on the bottom surface of the box body 1 to guide the bottom wheels of the germination vehicle 2 to enter and limit the placement position of the germination vehicle 2 in the box body 1.
