Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, and more particularly to a grain dryer capable of adjusting air inlet volume at multiple positions. Background Art

[0002] In the field of modern agricultural production, grain dryers are key equipment in the grain storage process, and their performance directly affects the storage quality and economic benefits of grain. However, the grain dryers currently on the market generally have the problem of rigid air intake system design. Their air intake position is often fixed and cannot be flexibly adjusted according to different grain varieties, moisture content and environmental conditions. This fixed air intake design leads to uneven heat distribution during the drying process, which may cause some grains to be insufficiently dried or over-dried, seriously affecting the drying quality and energy utilization efficiency.

[0003] More importantly, this design scheme that lacks the air inlet position adjustment function greatly limits the adaptability and working efficiency of the equipment in actual application. The air flow distribution and heat requirements required for drying will change in different seasons and weather conditions. The fixed air inlet position cannot meet the needs of this dynamic adjustment. At the same time, different grain varieties have different requirements for drying airflow due to their physical properties, and existing equipment cannot make corresponding adjustments to these differences. This not only reduces the drying effect, but may also lead to energy waste and even affect the quality of the grain, ultimately causing economic losses. Utility Model Content

[0010] The present invention is further configured such that a plurality of springs are provided between the sealing disk and the insertion tube, and the plurality of springs are respectively and equidistantly arranged, and the design of the springs ensures the transmission of pressure.

[0011] The utility model is further configured such that the rotating mechanism includes a transmission shaft and stirring blades, the transmission shaft is rotatably connected in the drying box, a plurality of stirring blades are installed, and the plurality of stirring blades are equidistantly installed on the side walls of the transmission shaft, and the design of the rotating mechanism ensures the continuity of stirring.

[0013] Compared with the prior art, the present invention provides a grain dryer capable of adjusting the air intake at multiple positions, which has the following beneficial effects:

[0014] 1. The adjustment mechanism realizes stable support of the overall structure through the rotation connection between the support frame and the drying box. Multiple air inlet pipes realize flexible adjustment of the air inlet position through the sliding cooperation between the insertion tube and the follower sleeve. The follower ball realizes precise positioning through the cooperation of the vertical groove and the stop groove. The rotation connection between the threaded sleeve and the follower sleeve provides a reliable fixing function. This design not only realizes multi-point adjustment of the air inlet position, but also ensures the accuracy and stability of the adjustment through the precise positioning mechanism.

[0015] 2. The sealing mechanism achieves reliable sealing of the air intake system through the cooperation of the rubber ring and the sealing disk. The two ends of the rubber ring are respectively connected to the insertion tube and the sealing disk to form a sealing structure.

The multiple stirring blades distributed at equal distances ensure the full stirring of grains. This design not only improves the drying efficiency, but also avoids the problem of partial over-drying or under-drying through uniform stirring, thus significantly improving the drying quality.

A threaded sleeve 9 is threaded on the air inlet pipe 3, and the follower sleeve 5 is rotatably connected in the threaded sleeve 9. The sealing mechanism includes a rubber ring 10 and a sealing disk 11. The two ends of the rubber ring 10 are respectively connected to the insertion tube 4 and the sealing disk 11. The sealing disk 11 fits in the air inlet pipe 3. There are multiple springs 12 between the sealing disk 11 and the insertion tube 4. The multiple springs 12 are equidistantly arranged. The rotating mechanism includes a transmission shaft 13 and a stirring blade 14. The transmission shaft 13 is rotatably connected in the drying box 2.

[0027] In this embodiment, when it is necessary to adjust the air inlet position at the bottom of the drying box 2 according to different situations, the insertion tube 4 is first inserted into the air inlet pipe 3, and then the sealing disk 11 is fit into the air inlet pipe 3. At this time, the follower ball 6 is slid along the vertical groove 7 so that the follower ball 6 is inserted into the stop groove 8, and then the threaded sleeve 9 is rotated to pull the insertion rod downward, and pressure is applied to the sealing disk 11 through the spring 12, thereby ensuring the sealing effect.

Since the insertion tube 4 is connected to the external air inlet equipment, hot air can be introduced into the corresponding position, and then the drying process is carried out. When the other positions do not need ventilation, it is only necessary to replace the sealed insertion tube 4 to seal it. After the hot air is introduced, the drive shaft 13 will be driven to rotate under the action of the motor 15. Since the grain is in the drying box 2, it will be flipped back and forth by the stirring blades 14, and the grain will be dried by the hot air, thereby completing the drying process.
