Description

Technical Field

[0001] The utility model belongs to the technical field of grain drying, and particularly relates to an energy-saving device for grain drying. Background Art

[0002] Grain drying is a process that removes moisture from grain to maintain its quality and ensure safe storage. This process typically involves the use of specialized equipment, such as a grain dryer, which uses heated air or other forms of heat to evaporate the moisture from the grain, thereby reducing its moisture content. Drying primarily prevents grain from spoiling, preserving its freshness and quality, while also improving storage safety and extending its shelf life.

[0003] However, the hot air blown out by the drying device can only come into contact with the grain during the falling process, resulting in a short contact time between the hot air and the grain. As a result, the drying device needs to consume a large amount of electricity to heat the air, and the grain needs to be repeatedly fed in order to dry the grain. Utility Model Content

[0026] Reference Figure 1-3 , an energy-saving device for grain drying shown, comprising a drying shell 1, the top and bottom of the inner wall of the drying shell 1 are slidably connected with a grain drying energy-saving structure 7;

[0027] The grain drying energy-saving structure 7 includes a first guide shell 701 and a second guide shell 702. The first guide shell 701 is arranged directly below the second guide shell 702. The bottom of the second guide shell 702 is provided with a discharge port. The top of the second guide shell 702 is provided with a blocking bar 708. The interior of the second guide shell 702 is provided with a second air vent 709. The second guide shell 702 and the first guide shell 701 are arranged at an angle. The heating device heats the heating tube 3 and then starts the fan blades 4. The fan blades 4 send external air into the interior of the drying shell 1 and take away the temperature of the surface of the heating tube 3. The heated air then dries the grain falling from the second guide shell 702 to the first guide shell 701. At the same time, the heated air will also enter the interior of the second guide shell 702 through the second air vent 709, so that the heated air contacts the grain moving downward inside the second guide shell 702, thereby achieving the energy-saving effect of the drying device and improving the efficiency of grain drying.

[0028] Furthermore, in the above technical solution, a grain inlet 2 is provided at the top of the drying shell 1, a heating tube 3 is provided on the inner wall of one side of the drying shell 1, a fan blade 4 is provided on the outer wall of one side of the drying shell 1, and a belt conveyor 5 is provided at the bottom of the drying shell 1. The grain enters the grain drying energy-saving structure 7 inside the drying shell 1 through the grain inlet 2, and then a discharge port is also provided at the bottom of the first guide shell 701 at the bottom of the drying shell 1, so that the dried grain can be discharged through the belt conveyor 5.

[0029] Furthermore, in the above technical solution, a rotating cam 6 is provided on the outer wall of the other side of the drying shell 1, and the number of the rotating cams 6 is set to two. The two rotating cams 6 are connected by a belt transmission device 8, and the lifting plate 704 is slidingly connected to the rotating cam 6. The number of the first air vents 705 is set to multiple, and the motor is started. The motor drives the rotating cam 6 to rotate through the belt transmission device 8, and then the rotating cam 6 pushes the lifting plate 704 to lift and lower. The lifting plate 704 drives the first guide shell 701 and the second guide shell 702 to lift and lower. The second guide shell 702 and the first guide shell 701 cause the grain to vibrate, thereby causing the grain to move downward from the blocking bar 708 of the upper layer. The blocking bar 708 can block the grain to prevent the grain from sliding directly down along the inclined first guide shell 701 and the second guide shell 702.

[0030] Furthermore, in the above technical solution, auxiliary grooves are provided on both sides of the inner wall of the drying shell 1, and slide bars 706 are provided on both sides of the outer walls of the first guide shell 701 and the second guide shell 702, the slide bars 706 are slidably connected to the auxiliary grooves, and a return spring 707 is provided between the auxiliary grooves and the slide bars 706. When the first guide shell 701 and the second guide shell 702 move upward, the first guide shell 701 and the second guide shell 702 drive the slide bars 706 to move upward on the inner wall of the auxiliary groove and squeeze the return spring 707, and then the return spring 707 pushes the slide bars 706 to reset, so that the lifting plate 704 is always in contact with the rotating cam 6. When the first guide shell 701 and the second guide shell 702 are lifted or lowered, the grain placed on the top of the first guide shell 701 and the second guide shell 702 can be vibrated to turn the grain over.

[0031] Furthermore, in the above technical solution, a side plate 703 is provided on one side of the first guide shell 701 , a lifting plate 704 is provided in the middle of the side plate 703 , and a first air vent 705 is provided inside the side plate 703 .

[0032] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
