DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0030] See also Figure 1-5 As shown, the utility model is a drying and airing device, comprising a base frame 1, a chain conveyor 2, an electric heat air guide box 3, and a fan 4. The chain conveyor 2 is fixed in the middle of the base frame 1. Two directional wheels 5 and two universal wheels 6 are fixed on the lower surface of the base frame 1. A rectangular vertical plate 7 plugged with the chain conveyor 2 is fixed at the four corners of the upper surface of the base frame 1. A row of fans 4 are installed in the electric heat air guide box 3. A cover 8 is installed on the upper end of the electric heat air guide box 3. Synchronous grain conveyors 9 are installed at both ends of the base frame 1.
[0031] Among them, the structure of the synchronous grain conveyor 9 specifically includes a motor 91, two dial wheels 92 and two circular arc shovel plates 93 matched with the dial wheels 92. The dial wheel 92 includes a round shaft rod 921 connected and matched with a seat bearing. The round shaft rod 921 is coaxially arranged with the inner arc surface of the circular arc shovel plate 93. The gap between the upper end of the circular arc shovel plate 93 and the end of the chain plate conveyor 2 is not more than 1mm. A coaxially arranged cylindrical body 922 is fixed to the outer wall of the round shaft rod 921. Six dial plates 923 are fixed to the outer wall of the cylindrical body 922. The distance between the free end of the dial plate 923 and the inner arc surface of the circular arc shovel plate 93 is not more than 1mm. The two circular arc shovel plates 93 are symmetrically fixed at both ends of the chassis 1. The two dial wheels 92 are respectively installed at the two ends of the chassis 1 through two seat bearings. The motor 91 is installed at one end of the chassis 1. A first sprocket 94 is fixed to the same end of the two dial wheels 92. The two first sprocket wheels 94 are driven by a chain 95. A second sprocket 96 for driving the chain 95 is mounted on the output shaft of the motor 91 .
[0032] The two dial wheels 92 in the synchronous grain conveyor 9 cooperate with two arc shovel plates 93. The front dial wheel 92 pushes the corn layer spread out and dried in the drying yard to the chain conveyor 2 for transportation. The electric heating air guide box 3 dries the corn moving on the chain conveyor 2. The corn transported by the chain conveyor 2 is thrown backwards through the rear dial wheel 92, and a corn layer is formed in the drying yard again for ventilation, drying and cooling.
[0033] Among them, the electric heating air guide box 3 includes a rectangular cylinder 31. A handrail 32 is installed on the upper half of the rear wall of the rectangular cylinder 31. A door hole 33 for grain to pass through is opened on the front and rear walls of the lower end of the rectangular cylinder 31. A separation plate 34 is fixed to the inner wall of the upper half of the rectangular cylinder 31. A rectangular through hole 35 cooperating with the rectangular vertical plate 7 is opened at the four corners of the separation plate 34. A row of cylinders 36 arranged along the conveying direction of the chain conveyor 2 is fixed through the middle of the separation plate 34. The lower half of the inner wall of the cylinder 36 is installed with an electric heating wire 10. The fan 4 is installed at the upper end of the cylinder 36. A return air duct 37 is fixed on both sides of the separation plate 34 located in a row of fans 4. A rectangular notch 38 is opened at the lower end of the return air duct 37 relative to the side wall of the chain conveyor 2. A rectangular flange ring 39 connected and matched with the cover 8 is fixed to the upper end of the rectangular cylinder 31.
[0034] A row of fans 4 inside the electric heating air guide box 3 provides a flowing airflow, and the electric heating wire 10 installed therein heats the airflow and blows it directly downward to the corn moving on the chain conveyor 2 to dry the corn, and then the return air guide pipes 37 on both sides re-involve part of the hot air and new air in the airflow reheating cycle to dry the corn, effectively reducing energy consumption. The handrail 32 installed at the rear of the electric heating air guide box 3 facilitates the whole device to move forward and backward and change direction, and is easy to operate.
[0035] The cross section of the separation plate 34 is a "〔"-shaped structure. The return air guide pipe 37 is placed on the inclined surface of the separation plate 34, and the inclined surface increases the air outlet range. The cylinder 36 is placed on the flat surface of the separation plate 34.
[0036] In order to filter the refluxed hot air, a filter screen 11 is installed on the surface of the separation plate 34 just above the reflux air guide pipe 37. The filter screen 11 filters debris when the machine is in use, and the intercepted debris will fall naturally under the action of gravity when the machine is stopped, reducing the difficulty of maintenance.
[0037] The working process of the utility model is: the device is started, and the motor 91 drives the dial wheel 92 of the synchronous grain feeder 9 to push the corn layer in the drying yard to the chain conveyor 2. The chain conveyor 2 transports the corn to the electric heating air guide box 3, and is dried under the action of hot air. The dried corn is output from the other end of the chain conveyor 2, and is thrown back to the drying yard through the rear dial wheel 92 of the synchronous grain feeder 9 to form a new corn layer for ventilation, drying and cooling. In the electric heating air guide box 3, the airflow generated by the fan 4 is directly applied to the corn after being heated by the electric heating wire 10, and the return air guide pipe 37 recirculates part of the hot air and the new air to jointly participate in the drying operation.
