DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4As shown, the present embodiment provides a grain suction device with a drying function, comprising a base 1, a grain storage cylinder 2 is installed at the middle position of the top of the base 1, a fan 3 whose input end is connected to the inside of the grain storage cylinder 2 is installed on one side of the top of the base 1, a transverse tube 4 is fixed at the top of the base 1 parallel to the feed port of the grain storage cylinder 2, a conduction mechanism is provided at the end of the transverse tube 4 and the feed port of the grain storage cylinder 2, a hose 5 is installed at one end of the transverse tube 4 away from the grain storage cylinder 2, rubber plates 14 are evenly provided on the inner wall of the hose 5 along the length direction of the hose 5, and electric heating wires 15 are provided inside the rubber plates 14, the rubber plates 14 protect the electric heating wires 15 to prevent the electric heating wires from being excessively deformed and causing breakage, a grain suction pipe 6 is installed at one end of the hose 5 away from the transverse tube 4, and a flow regulating mechanism is provided inside the grain suction pipe 6.

[0025] The overall working principle: when in use, the grain suction pipe 6 is inserted into the grain pile, and then the fan 3 is started to generate negative pressure inside the grain storage cylinder 2, and the grain enters the grain storage cylinder 2 through the hose 5 and the cross pipe 4. In the process of sucking grain, if the dryness of the grain is insufficient, the heating wire 15 is conductive, and the heating wire 15 generates heat and transfers it to the rubber plate 14. The heating temperature of the heating wire 15 is lower than the melting point of the rubber plate 14. The surface of the rubber plate 14 has a certain temperature, and the grain will be heated and dried when passing through. In addition, due to the different types and sizes of grains, the flow regulating mechanism is used to adjust the size of the open end of the grain suction pipe 6, and then the suction force and the feeding rate can be adjusted to ensure the effect of sucking grain.

[0026] In this embodiment, a support rod is fixed between the bottom of the transverse tube 4 and the base 1, and a placement rack is provided at the top of the base 1 near the support rod.

[0027] Partial working principle: The use of the support rod ensures the stability of the cross pipe 4, and the use of the placement rack can limit the grain suction pipe 6 after use.

[0028] In this embodiment, the conduction mechanism includes a motor 7, a shaft 8, a first replacement tube 9, a second replacement tube 10, a spiral blade 11, a heating bin 12 and a heating plate 13. The motor 7 is installed at the top end of the transverse tube 4, and the output end of the motor 7 faces the feed port of the grain storage cylinder 2. The output end of the motor 7 is installed with a shaft 8, the first replacement tube 9 is fixed on one side of the shaft 8, and the second replacement tube 10 is fixed on the other side of the shaft 8. The diameters of the shaft 8 and the second replacement tube 10 are the same as the diameter of the transverse tube 4. The interior of the second replacement tube 10 is provided with a spiral blade 11 along the length direction, the outer side of the second replacement tube 10 is provided with a heating bin 12, and the interior of the heating bin 12 is provided with a heating plate 13.

[0029] Local working principle: During the use of the device, when the humidity of the grain is low and it can be dried by heating with the heating wire 15, the first replacement pipe 9 is connected between the horizontal pipe 4 and the feed port of the grain storage cylinder 2. When the humidity of the grain is high and it cannot be completely dried only by heating with the heating wire 15, the motor 7 is started to connect the second replacement pipe 10 between the horizontal pipe 4 and the feed port of the grain storage cylinder 2, and the power supply of the heating sheet 13 is turned on to heat the grain passing through the second replacement pipe 10. In addition, the use of the spiral blade 11 increases the residence time of the grain inside the second replacement pipe 10 to ensure the drying effect.

[0030] In this embodiment, rubber sealing rings are provided at one end of the horizontal pipe 4 close to the first replacement pipe 9 and at the feed port of the grain storage cylinder 2.

[0031] Local working principle: During the process of swapping the positions of the first replacement pipe 9 and the second replacement pipe 10, the rubber sealing ring can ensure the sealing effect of the connection.

[0032] In this embodiment, the flow regulating mechanism includes a sector baffle 16, a connecting rod 17, a through groove 18, a sleeve 19 and a positioning bolt 20. The sector baffle 16 is hinged to the inner wall of the grain suction pipe 6, and the sector baffles 16 are evenly arranged circumferentially. A sleeve 19 is sleeved outside the grain suction pipe 6, and a connecting rod 17 is hinged and installed between the outside of the sleeve 19 and the side of the sector baffle 16. Through grooves 18 matching with the connecting rod 17 are evenly opened on the outside of the grain suction pipe 6 in the circumferential direction. The connecting rod 17 passes through the inside of the through groove 18, and the through groove 18 is strip-shaped. A positioning bolt 20 is installed on the outside of the sleeve 19 by threading.

[0033] Local working principle: When adjusting the size of the feed port of the grain suction pipe 6, control the sleeve 19 to slide inside the grain suction pipe 6, use the connecting rod 17 to push the sector baffle 16, and the sector baffles 16 expand or close simultaneously, thereby adjusting the size of the feed port of the grain suction pipe 6, and then use the positioning bolt 20 to fix the position of the sleeve 19 to stabilize the size of the feed port of the grain suction pipe 6.

[0034] In this embodiment, handles are symmetrically fixed on the outside of the sleeve 19, and the shape of the handle is U-shaped.

[0035] Local working principle: When adjusting the size of the feed port of the grain suction pipe 6, the use of the handle facilitates the pushing of the sleeve 19.

[0036] In this embodiment, a protective cover 21 is fixed at one end of the grain suction pipe 6 away from the hose 5, and the shape of the protective cover 21 is hemispherical.

[0037] Local working principle: By using the protective cover 21, impurities are prevented from entering the inside of the grain suction pipe 6 to ensure the stable operation of grain suction.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
