Description

A constant temperature and ventilation seed soaking box

technical field

The utility model relates to a seed soaking device, which belongs to the technical field of agricultural and forestry plant propagation.

Background technique

In the prior art, many crops, fruit trees, trees, etc. need to be soaked before the seeds are sown. When soaking the seeds, the seeds are soaked in water or various solutions. Kill some eggs and viruses. The moisture content of dried seeds is usually below 15%, the physiological activity is very weak, and they are in a dormant state. After the seeds absorb water, the seed coat swells and softens, the oxygen dissolved in water enters the cells along with the water, and the enzymes in the seeds also start to activate. Due to the action of enzymes, the respiration of the embryo is enhanced, and the insoluble substances stored in the endosperm are gradually transformed into soluble substances, which are transported to the embryo along with the water. Seed embryo obtains moisture, energy and nutrient substance, and under suitable temperature and oxygen condition, cell begins to divide, elongate, breaks through glume, and to make seed germinate, it must first make it absorb enough water. However, the seed does not germinate with water, it must absorb at least 15-18% of its own weight in water to start to germinate. Only when the water absorption reaches 40% of its own weight can it germinate normally. In the prior art, the original method of soaking seeds in potted water is mostly used. The disadvantages are: one, the water absorption of the seeds is not easy to control, and people need to replant the seeds regularly. During the replanting process, it is easy to damage the germ; , the seeds are soaked in water, easy to ferment and make local high temperature, burn the germ; third, the temperature is not easy to control.

Utility model content

The purpose of the utility model is to provide a constant temperature and ventilation seed soaking box, which can overcome the defects in the prior art, realize constant temperature seed soaking, the seeds have good ventilation, and the problem of stuffy soaking and fermentation will not occur.

The purpose of this utility model is achieved in this way: a kind of constant temperature and ventilation seed soaking box includes an outer box body, two opposite inner side walls of the outer box body are respectively uprightly fixed with guide rails, and a slide block is arranged in the guide rails, and the outer box body The box body is also connected with the cylinder block of the cylinder through the cylinder seat, and the piston rod extension end of the cylinder is connected with the slider. An inner box body that can be lifted and lowered with the slider is arranged between the sliders. The water-permeable hole is provided with a heating device at the bottom of the outer box body, and the heating device is located below the inner box body.

When the device is in use, a certain amount of seed soaking liquid is added to the outer box. Usually, the soaking temperature will be higher than the ambient temperature. The heating device can control the temperature of the soaking liquid. Under the action of the cylinder, the inner box can rise and fall stably with the slider. Movement, the seeds placed in the inner box can be immersed in the soaking solution, and the seeds can also be lifted out of the soaking solution to realize intermittent seed soaking. The time of immersing in the soaking solution and the time of leaving the soaking solution can be allocated through program control. Ratio, in order to be properly adjusted according to different plant varieties. When the seeds leave the seed soaking solution, the seeds themselves are ventilated and can fully contact with the oxygen in the air to ensure the oxygen for the seeds to breathe. When the internal temperature of the seeds is high, the seed soaking liquid can also be a cooling liquid, which can keep the seeds in the inner box in a constant temperature environment as a whole. Soaking seeds with this device can achieve constant temperature soaking, the seeds have good ventilation, and there will be no problem of stuffy soaking fermentation. The germination rate of seeds is high, and the germination time is neat and controllable, which facilitates the management after sowing; It can also be used in the production of tallow, sweetgum, maple and other forest trees, and in the production of rice, cotton and other crops.

In order to achieve the effect of heat preservation and ventilation, a box cover is provided at the upper opening of the outer box body, and a number of ventilation holes are provided on the box cover. The box cover has the function of dustproof and heat preservation, and the vent hole has the function of ventilation.

As a further improvement of the utility model, a fan is provided on the box cover. Turn on the fan when necessary. The fan has the functions of ventilation and heat dissipation, which can further ensure the ventilation and constant temperature of the seeds.

In order to improve the scope of application of the inner box, a partition is arranged horizontally in the inner box, and a plurality of micropores are arranged on the partition. The separator is detachable and replaceable, and for seeds of different particle sizes, it can be replaced with a separator that matches the micropore size. In order to strengthen the support, a number of support ribs are provided on the lower side of the partition to support the bottom of the inner box.

In order to facilitate cleaning of the outer box, an emptying port is provided on the bottom side of the outer box.

For the convenience of taking out the inner box as a whole and putting it into the outer box, the slider is provided with a protrusion, and the outer edge of the upper mouth of the inner box is provided with a convex edge, and the convex edge rests on the protrusion.

For the convenience of manipulation, an electric control box is installed on the outer wall of the outer box.
