When using this dryer, first ensure that the grain discharge mechanism of the grain discharge mechanism is closed, and then pour the grain into the grain storage bin. After finishing the preparatory work, start the drying, and the hot air blower will work to provide hot air to the drying chamber. The auger motor drives the auger to lift the grain in the storage bin to the upper part of the drying bin, and falls into the drying bin from the auger mouth. There is a multi-layer bucket cone structure in the drying bin. After the grains are gathered by the bucket-shaped baffles and dispersed by the cone-shaped baffles, the drying area in the drying bin is greatly improved at the same height, and the grains are also can be fully dispersed. The grain is in contact with the hot air blown from bottom to top for a long time, which greatly improves the drying efficiency. The grain is dried thoroughly and evenly, which greatly reduces the damage rate of the grain during the drying process. The falling grains finally fall into the grain storage bin again, waiting for the next drying cycle. The hot air enters the pipe at the top of the drying bin, is reheated by the hot air blower, and then enters the dryer again. During the drying process, the staff can detect parameters such as grain humidity and temperature from the touch screen. When the humidity in the drying chamber is too high, the exhaust fan will automatically work to exhaust the moisture in the drying chamber. After several cycles, drying is finally completed. After the drying is completed, the grain discharge can be started, the air pump supplies air to the cylinder, the cylinder drives the grain discharge mechanism, the grain discharge port at the lower part of the grain storage bin is opened, the grain discharge starts, the grain discharge is completed, and this drying is over.

One side of the grain lifting rod 2 has an auger motor 4, and the transmission belt 15 is sleeved on the rotating shaft of the auger motor 4 and the upper end of the rotating shaft of the auger of the grain lifting rod 2, and the rotating shaft of the auger motor 4 passes through the transmission belt 15 drives the rotating shaft of the auger of the grain lifting rod 2 to rotate, the hot air blower 10 is on the other side below the drying bin housing 3, and the top and the lower side of the drying bin housing 3 have connection holes. The two interfaces of the hot air blower 10 are respectively connected to the connection holes on the top and the bottom side of the drying bin housing 3 through the air supply duct 9, and the upper end side of the grain lifting rod 2 is connected to the drying bin housing 3, and the There are temperature sensors and humidity sensors in the drying bin shell 3. In order to facilitate the control of the grain situation in the grain dryer, a temperature sensor and a humidity sensor are provided. There are 1- 5 drying modules and a slide plate 7, each drying module includes a bucket-shaped baffle 5 and a cone-shaped baffle 6, the lower cone of the bucket-shaped baffle 5 of the drying module is hollow and A square prism without upper and lower bottom surfaces, that is, a funnel with a large upper hole and a small lower hole formed by the sides of the prism; the upper cone of the conical baffle plate 6 of the drying module is a hollow and bottomless quadrangular pyramid. The top is upward, and it is facing the center of the lower part of the bucket-shaped baffle 5. After testing, the drying module with the above structure can achieve the best drying effect. Corresponding to the tip of the top, there are 4 strip-shaped gaps of 1cm-15cm between the outer side of the cone-shaped baffle 6 and the drying chamber shell 3, and the drying of the sliding material plate 7 at the bottom is Below the module, there is an opening on the lower side of the drying bin shell 3, the sliding material plate 7 protrudes into the grain storage bin 1 along the opening, and there is a dehumidification mechanism in the top of the drying bin shell 3, The dehumidification mechanism is a ventilator 8, and the ventilator 8 is fixed on the top side of the drying bin shell 3, and one side of the ventilator 8 is connected with the hole of the drying bin shell 3, and the ventilator 8 8 On the other side, there is an air outlet 11 protruding out. In order to prevent the humidity from being too high, the present invention specially designs a corresponding dehumidification mechanism. When the humidity exceeds the standard, the ventilation process is carried out through the dehumidification mechanism.
本发明烘干机优点如下： The advantages of the drying machine of the present invention are as follows:
1、本发明烘干部分主体采用斗锥状结构，可以极大利用烘干仓内的空间，节约材料。 1. The main body of the drying part of the present invention adopts a bucket-cone structure, which can greatly utilize the space in the drying chamber and save materials.
2、本发明谷物在斗锥状烘干斜面上运动，与其他形状的烘干斜面相比（如图4所示）在相同高度内烘干面积增加约70%~80%，即在烘干过程中，谷物与烘干斜面的接触面积增加了约70%~80%，，即谷物被摊蒲了，这有效增加了平均每粒粮食与干燥热空气充分接触的面积，使谷物的烘干有效、均匀，降低了谷物在烘干过程中的损坏率，也提高了谷物的烘干效率。 2. The grains of the present invention move on the bucket cone-shaped drying slope. Compared with other shapes of drying slopes (as shown in Figure 4), the drying area increases by about 70% to 80% at the same height, that is, when drying During the process, the contact area between the grain and the drying slope increases by about 70%~80%, that is, the grain is spread out, which effectively increases the average area of each grain in full contact with the dry hot air, so that the drying of the grain Effective and uniform, it reduces the damage rate of the grain during the drying process, and also improves the drying efficiency of the grain.
3、烘干过程采用逆流烘干，粮食流从上向下落，热空气从下向上升，在烘干仓的下部，较热的热空气与经过烘干一段时间温度较高的粮食相遇，在烘干仓上部温度较低的热空气与刚刚落入的粮食相遇，粮食所收到的烘干温度逐步上升，粮食温度均匀上升，降低爆腰率，提高烘干质量，同时也极大地利用了热能，利于节约能源。 3. The drying process adopts countercurrent drying, the grain flow falls from top to bottom, and the hot air rises from bottom to top. In the lower part of the drying bin, the hotter hot air meets the grain with a higher temperature after drying for a period of time. The hot air with a lower temperature in the upper part of the drying bin meets the grain that has just fallen in, and the drying temperature received by the grain rises gradually, and the temperature of the grain rises evenly, which reduces the bursting rate and improves the drying quality. Heat energy, which is conducive to energy saving.
4、经过一轮烘干后的热空气没有立即排走，而是通过热风机进行二次加热，确保余热的再利用，提高热能利用率。烘干完成后，气泵向气缸供气，气缸带动排粮板，进入自动排粮，方便快捷，节约人力。 4. The hot air after one round of drying is not discharged immediately, but is reheated by the hot air blower to ensure the reuse of waste heat and improve the utilization rate of heat energy. After the drying is completed, the air pump supplies air to the cylinder, and the cylinder drives the grain discharge plate to enter the automatic grain discharge, which is convenient and quick, and saves manpower.
5、当烘干仓内湿度过大时，排气扇自动打开，自动调节烘干仓烘干条件，确保烘干最优。 5. When the humidity in the drying chamber is too high, the exhaust fan will automatically open and automatically adjust the drying conditions of the drying chamber to ensure optimal drying.
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作任何其他形式的限制，而依据本发明的技术实质所作的任何修改或等同变化，仍属于本发明所要求保护的范围。 The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any other form, and any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope of protection claimed by the present invention .
