Description

A suction and exhaust type dryer

technical field

The utility model relates to a seed drying machine, in particular to a drying machine of the exhaust air type.

Background technique

There are usually two types of seed drying methods: natural drying and artificial mechanical drying: natural drying uses methods such as sun exposure, ventilation and spreading to reduce the level of seeds. The method is simple, economical and safe, and is especially suitable for small batches of seeds. Seeds must be dried by the method of clearing the field and pre-drying, thinly spread and frequently turned, and placed in the warehouse at the right time to prevent condensation and moisture; artificial mechanical drying method, hot air drying Due to the large batch of specialized seed production, natural drying is sometimes affected by climatic conditions. The natural air-drying method is not suitable for large-scale seed production. At this time, it is necessary to establish a seed drying plus factory to dry the seeds with hot air. The working principle is: under certain conditions, increasing the temperature of the air can change the moisture content of the seeds and the relative humidity of the air. balance relationship. Different types of seeds, different regions, the heating machinery and the layout of the drying room are also different. However, the following items should be paid attention to when drying seeds by this method: never put the seeds directly on the heater to dry; the temperature of the seeds should be strictly controlled; The multiple gap drying method is adopted; the dried seeds need to be cooled to normal temperature before they can be put into the warehouse.

However, there are still some problems with the current seed drying equipment: drying at a suitable temperature and operating according to the regulations will still reduce the vitality and integrity of the seeds, which will reduce the survival rate of the seeds, which is not conducive to fine planting control, and is easy to Cavitation problems.

Utility model content

The purpose of this utility model is to provide a kind of drying machine of exhaust air type, solve the problem that the survival rate of existing seeds is reduced after drying, improve the survival rate of seeds, and reduce the chance of cavities and dead cavities in the planting process. Filter to achieve the purpose of precise planting.

The purpose of this utility model is achieved through the following technical solutions:

The function of the turning mechanism is to turn the seeds over during use to make them evenly heated and avoid scorching. After long-term research, the applicant found that such a drying box still cause seed death, although the proportion of death is small, it will also affect the emergence rate of refined planting. After long-term analysis, the applicant found that these dead seeds should not be caused by excessive heat or mechanical blows. Yes, the cause of its death is lack of oxygen. During the process of dehydration, there will be a peak respiration period. This time is very short, only a few minutes. During this process, the seeds will inhale oxygen, but, in There is always a dead angle in the drying box, and the seeds cannot breathe oxygen at a specific time, so they die. In response to this phenomenon, the applicant has made long-term research and improvement, and installed a spiral air intake pipe on the drying box. The spiral air intake pipe adopts The three pipes are twisted spirally, and the output pipe of the fan is connected with the spiral inlet pipe through a diameter-expanding elbow. When necessary, fresh air is blown into the drying box at intervals, and the output gas of the fan is formed in the pipe. Airflow, after the airflow passes through the spiral air inlet pipe, the direction of its air outlet is along the tangential direction of each gate, so that the area of the air outlet increases, which is conducive to blowing fresh air to each dead corner. There is also a The exhaust port, the exhaust port is equipped with an exhaust pipe, and the exhaust pipe is connected to the air pump. The exhaust port and the spiral air intake pipe are respectively located on the body diagonal in the space above the turning mechanism. When it is necessary to inhale air, you can first Through the operation of the air pump, a certain negative pressure is formed in the drying box, and then the fresh air can be quickly distributed in all corners of the drying box under the dispersion effect of the spiral intake pipe and the guidance of the negative pressure, thereby avoiding air pollution. The generation of dead ends.

Completely solve the problem of air dead angle, so that the seeds can breathe fresh air and improve the survival rate of seeds.

The turning mechanism includes a rotating shaft installed between two sides of the drying box, on which a helical blade is arranged, and the rotating shaft passes through the drying box and is connected with a driving mechanism.

The drive mechanism includes a motor, a turntable is arranged on the rotating shaft, and the output of the motor drives the turntable to rotate through a belt. The motor drives the belt, the belt drives the turntable, the turntable drives the rotating shaft, and the rotating shaft drives the helical blades, so as to realize the stir frying of the seeds and prevent the seeds from being scorched.

A material guide groove corresponding to the material outlet is arranged on the support. In the equipment of the utility model, fresh seeds are put into the top, and after drying, the motor is reversed, driven by the spiral blade, it can come out from the discharge port at the bottom of the drying box, and be transported to a specific position through the material guide groove.
