Referring to fig. 6 and 7, fig. 6 is a schematic structural diagram of a door panel of an automatic grain discharging device of a grain dryer according to an embodiment of the present invention when the door panel of the automatic grain discharging device of the grain dryer is closed, fig. 7 is a schematic structural diagram of the door panel of the automatic grain discharging device of the present invention when the door panel is opened, a first limit switch 57 and a second limit switch 58 are further disposed on the right side plate 54, the second limit switch 58 is installed above the first limit switch 57, the installation position of the first limit switch 57 is the lowest point of the travel of the cam follower 32, and the installation position of the second limit switch 58 is the highest point of the travel of the cam follower 32. The first limit switch 57 and the second limit switch 58 are connected with the control cabinet. The frame 33 of the cam assembly 3 is fixed to the left side plate 53. The front side plate 51, the rear side plate 52 and the upper cover plate 55 are all provided with connecting plates 56, bolt holes are formed in the connecting plates 56, and the casing 5 is detachably connected with other components through the connecting plates 56.
As shown in fig. 5, the power unit 4 includes a motor 41, a motor bracket, and a speed reducer 42. The first end of the motor 41 is fixed to a motor bracket fixed to the front side plate 51 of the housing 5. The second end of the motor 41 is connected to a first end of the speed reducer 42, and the second end of the speed reducer 42 is connected to a circular hole of the cam 31. The motor 41 is also connected with a control cabinet, which provides power for the motor 41 and controls the motor 41 to be turned on and off. When the motor 41 is operated, the speed reducer 42 connected with the motor drives the cam 31 to rotate.
As shown in fig. 6, when the door panel 21 is in a horizontal position to contact the bottom of the square hopper 12, the discharging state is stopped. When stopping the grain discharge, the radius of curvature of the cam 31 is the largest. At this time, the rectangular square at the first end of the cam follower 32 is flush with the first limit switch 57, the first limit switch 57 transmits a signal to the control cabinet, and the control cabinet cuts off the power supply of the motor 41, so that the motor 41 stops working. The cam 31 now restrains the connecting rod 26 in the horizontal position by means of the cam follower 32. The spindle rod 26 is fixedly connected to the shaft 23, limiting the door panel 21 fixedly connected to the shaft 23 to a horizontal position. The horizontal door 21 contacts the bottom of the square hopper 12 to store grains in the grain storage tank 11.
As shown in fig. 7, when the door panel 21 rotates clockwise about the shaft 23, the door panel 21 is away from the bottom of the square hopper 12 to start the grain discharge state. When the grain discharge starts, the power part 4 drives the cam 31 to rotate, and the curvature radius of the cam 31 is gradually reduced. The gravity of grain in the grain storage tank 11 gives the door plate 21 a downward thrust, the connecting rod 26 starts to rotate clockwise by taking the center point of the shaft 23 as the center point, the sliding block 27 starts to slide upwards along the connecting rod 26, the sliding block 27 pushes the cam follower 32 connected with the sliding block 27 upwards, the cam follower 32 always contacts with the cam 31 because the curvature radius of the cam 31 is gradually reduced, the cam follower 32 moves upwards along the frame 33, when the curvature radius of the cam 31 is minimum, the rectangular square at the first end of the cam follower 32 is flush with the second limit switch 58, the second limit switch 58 transmits a signal to the control cabinet, the control cabinet cuts off the power supply of the motor 41, and the motor 41 stops working. The cam 31 prevents the cam follower 32 from continuing upward movement, at which point the door panel 21 is opened at a maximum angle.
The rotation of the cam 31 is converted into the reciprocating linear motion of the cam follower 32, and the cam follower 32 moves up and down between the first limit switch 57 and the second limit switch 58 to drive the link lever 26 to perform the circular arc motion centering on the shaft 23, thereby realizing the automatic opening and closing of the door panel 21.
Automatic grain discharging process: after the grain is dried, the grain enters the grain storage tank 11 of the tank body assembly 1, and the door plate 21 is in contact with the bottom of the square funnel 12 at the horizontal position and is in a state of stopping grain discharge. The humidity measuring instrument 14 on the grain storage tank 11 tests the humidity of grains, and the test data are displayed on the display screen of the control cabinet. In the automatic grain discharging mode, grain humidity requirements are set on a parameter setting interface of the control cabinet, when the grain humidity of the grain storage tank 11 reaches the set requirements, the motor 41 of the power component 4 is controlled by the control cabinet to start, the door plate 21 is opened, and grains enter the grain discharging port 13 through the square hopper 12.
The control cabinet is also provided with a manual motor 41 which is started manually through a button of a display screen of the control cabinet in a manual grain discharging mode.
Through automatic grain discharge, misoperation of manual grain discharge is prevented. Compared with manual grain discharge, automatic grain discharge realizes unattended operation, and reduces labor cost. In the embodiment, the bearing, the cam, the motor and the like are all arranged outside the box body in consideration of dust and sundries on the surface of grains, so that mechanical parts are prevented from running in an environment with higher dust and sundries content, mechanical abrasion is slowed down, and the reliability of the device is improved. The conical inclined plane replaces mechanical conveying and grain discharging, so that the breakage rate of grains is reduced.
