DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-6 As shown, a grain dryer convenient for dust removal comprises a first feeding part 1, a dust removal part 2, a second feeding part 3 and a drying part 4, wherein the first feeding part 1 is used to convey grains to the dust removal part 2, and the grains passing through the dust removal part 2 are conveyed to the drying part 4 through the second feeding part 3, and the dust removal part 2 comprises a column 5, a placement groove is arranged at the upper end of the column 5, a first motor 6 is arranged inside the placement groove, a turntable 7 is arranged at the upper end of the column 5, an output end of the first motor 6 is fixedly connected to the turntable 7, and a receiving part is evenly arranged on the outer surface of the turntable 7, and the receiving part comprises an extension plate 8 arranged on the outer surface of the turntable 7, side plates 9 are respectively arranged on both sides of the extension plate 8, and fixed pulleys 10 are respectively arranged at both ends of the side plate 9, a second motor 11 is arranged on the extension plate 8, a rotating shaft 12 is arranged at the output end of the second motor 11, and a wire wheel 1 is arranged on the rotating shaft 12 3. A material receiving box 14 is arranged below the extension plate 8. The upper and lower ends of the material receiving box 14 are open. The material receiving box 14 also includes a steel wire rope 15. One end of the steel wire rope 15 is fixedly connected to a corner of the material receiving box 14. The other end of the steel wire rope 15 is fixedly connected to the wire wheel 13 after passing the fixed pulley 10. A rotatable baffle 16 is symmetrically arranged at the lower end of the material receiving box 14. A pneumatic cylinder 17 is arranged on the outer surface of the material receiving box 14. A mounting groove 18 is arranged at the output end of the pneumatic cylinder 17. A support rod 19 is rotatably connected to each baffle 16. The movable end of the support rod 19 is rotatably connected to the mounting groove 18. The outer surfaces of the material receiving box 14 and the baffle 16 are covered with meshes. The material receiving box 14 and the baffle 16 also include a water receiving trough 20. A first water tank 21 and a second water tank 22 are arranged inside the water receiving trough 20. An ultrasonic generator 23 is arranged at the bottom of the first water tank 21 and the second water tank 22.

[0020] The first loading part 1 and the second loading part 3 can be screw conveyors or belt conveyors. The first loading part 1 and the second loading part 3 in the present application are both screw conveyors. The drying part 4 is dried by vibration and high-temperature airflow. The bolt conveyor and the drying part 4 are both existing technologies and will not be repeated here.

[0021] The column 5 is fixed on the ground. When the first motor 6 in the column 5 rotates, it can control the rotation of the turntable 7. By rotating the turntable 7, the positions of each accommodating part on the turntable 7 can be controlled. In the present application, the number of accommodating parts is four, and the four accommodating parts are arranged circumferentially on the turntable 7, and the angle between two adjacent accommodating parts is 90°.

[0022] By controlling the rotation of the second motor 11, the lifting and lowering of the material receiving box 14 can be controlled. Specifically, when the material receiving box 14 needs to be moved downward into the first water tank 21 or the second water tank 22, the second motor 11 is controlled to start, and the second motor 11 drives the rotating shaft 12 to rotate. The wire wheel 13 on the rotating shaft 12 unwinds the wound wire rope 15, thereby moving the material receiving box 14 downward, and the material receiving box 14 can enter the first water tank 21 or the second water tank 22. When the material receiving box 14 needs to be taken out of the first water tank 21 or the second water tank 22, the second motor 11 is controlled to rotate in the opposite direction.

[0023] The opening and closing of the lower end opening of the material receiving box 14 is controlled by the pneumatic cylinder 17. When the lower end opening of the material receiving box 14 needs to be controlled to be opened, the output end of the pneumatic cylinder 17 is extended, and the pneumatic cylinder 17 pushes the support rod 19 to move downward through the mounting groove 18. Since both ends of the support rod 19 are rotatably connected to the mounting groove 18 and the baffle 16, the two baffles 16 can be controlled to open, and the opening size of the lower end of the material receiving box 14 can be controlled by controlling the extension length of the output end of the pneumatic cylinder 17, so as to control the falling speed of the grains in the material receiving box 14. When the output end of the pneumatic cylinder 17 is retracted, the two baffles 16 can be controlled to close the lower end opening of the material receiving box 14.

[0024] The first water tank 21 and the second water tank 22 are both connected with a water inlet pipe and a drain pipe. The drain pipe is used to discharge the dirty water in the first water tank 21 and the second water tank 22, and the water inlet pipe is used to inject clean water into the first water tank 21 and the second water tank 22. The first water tank 21 is used to wash the grains for the first time, and the second water tank 22 is used to wash the grains for the second time. By setting an ultrasonic generator 23 in the first water tank 21 and the second water tank 22, the washing efficiency and washing effect of the grains can be improved. Since the water in the first water tank 21 is easier to get dirty than the water in the second water tank 22, the replacement frequency of the water in the first water tank 21 is higher than the replacement frequency of the water in the first water tank 21. At the same time, the grains located outside the first water tank 21 and the second water tank 22 need to be filtered to reduce the water content in the grains. The grains after filtering are transported to the drying part 4 through the second feeding part 3.

[0025] The stacking height of the grains in the receiving box 14 is not higher than 3 / 5 of the overall height of the receiving box 14, and when the grains are completely submerged in water, the upper end of the receiving box 14 is still above the water surface to prevent the grains from entering the first water tank 21 or the second water tank 22 through the upper end opening of the receiving box 14, and when the receiving box 14 is located in the first water tank 21 or the second water tank 22 and the grains are cleaned, the baffle 16 at the bottom of the receiving box 14 closes the lower end opening of the receiving box 14 to prevent the grains from leaking from the bottom of the receiving box 14.

[0026] Furthermore, a material guide cylinder 24 is provided at the unloading end of the first loading part 1, and the material guide cylinder 24 is located directly above the first water tank 21. A grain unloading channel is provided between the extension plate 8 and the side plate 9. The grain enters the receiving box 14 through the material guide cylinder 24 and the unloading channel. When the first loading part 1 transports the grain into the receiving box 14 through the material guide cylinder 24, the grain can pass through the unloading channel and directly enter the receiving box 14.

[0027] Furthermore, the lower end of the turntable 7 is open, and the turntable 7 is sleeved on the upper end of the column 5. A reinforcing plate 25 is provided between the extension plate 8 and the turntable 7. The reinforcing plate 25 can support the extension plate 8 to improve the stability of the receiving box 14 after loading the grains.

[0028] Furthermore, the water receiving trough 20 is arranged in a ring shape, and the column 5 passes through the middle of the water receiving trough 20 to prevent the column 5 from being rusted due to being immersed in water for a long time.

[0029] Working principle: The grains are conveyed to the receiving box 14 located above the first water tank 21 through the first feeding part 1 and the guide cylinder 24. When the quantitative grain conveying is completed, the first feeding part 1 stops feeding, and then the second motor 11 controls the wire wheel 13 to unwind, so that the receiving box 14 enters the first water tank 21, and then the ultrasonic generator 23 generates high-frequency vibration in the first water tank 21 to perform the first cleaning on the grains in the receiving box 14. After the grains are cleaned for the first time, the wire wheel 13 is controlled by the second motor 11 to be reeled, so that the receiving box 14 moves to the top of the second water tank 22, and then the first motor 6 is controlled to drive the turntable 7 to rotate, so that the receiving box 14 located above the first water tank 21 moves to the top of the second water tank 22, and then the second motor 11 controls the wire wheel to unwind, so that The receiving box 14 enters the second water tank 22, and the grains are cleaned for the second time by the ultrasonic generating device 23 and the water in the second water tank 22. After the second cleaning is completed, the circuit is reeled up by the second motor 11 to move the receiving box 14 to the top of the second water tank 22. Then the receiving box 14 is transferred to a position where there are no first water tank 21 and second water tank 22. The water mixed in the grains in the receiving box 14 directly falls into the water receiving trough 20, thereby reducing the moisture content of the grains in the receiving box 14. Then, the first motor 6 continues to control the rotation of the receiving box 14, and the drained receiving box 14 is moved to the position of the second loading section 3. Then, the pneumatic cylinder 17 is controlled to control the baffle 16 at the bottom of the receiving box 14 to open, so that the grains can be transported to the drying section 4 through the second loading section 3.

[0030] The device can remove dust mixed in the grains by washing with water. After two washings and one draining, the grains are transported to the drying section 4 for drying. The amount of dust in the dried grains is very small, which can effectively reduce the large amount of dust gas generated by vibration during drying, is beneficial to protecting the production environment, and has a good dust removal effect.
