Preferably, in order to avoid the separation of the ball screw bearing 16 from the screw rod 17, the air exhaust assembly further comprises a limit plate 30, and the limit plate 30 is fixedly connected with one end of the screw rod 17 far away from the paddle 18.

Through setting up limiting plate 30, restricted ball bearing 16's displacement for when ball bearing 16 removed along lead screw 17, ball bearing 16 can not break away from with lead screw 17, thereby can not lead to the fact the influence to the rotation of paddle 18, improved the reliability of equipment.

Preferably, in order to achieve the function of dust prevention, the air suction assembly further comprises a filter screen 31, the filter screen 31 is fixed inside the fixing box 20, and the filter screen 31 is arranged between the paddle 18 and the air inlet pipe 19.

Through setting up filter screen 31, carry out edulcoration work to the air that gets into in the heating pipe 22 to reduced the miscellaneous volume that contains in the inside air of entering main part 1, avoided the dust to get into main part 1 inside and the adhesion on the cereal grain, thereby improved the quality of cereal grain.

Preferably, in order to limit the moving direction of the moving rod 6, sliding grooves are formed on the inner walls of the two sides of the main body 1, two ends of the moving rod 6 are respectively arranged in the two sliding grooves, and the moving rod 6 is slidably connected with the sliding grooves.

Through setting up the spout for the carriage release lever 6 reciprocates along the spout, thereby has restricted carriage release lever 6's moving direction, avoids carriage release lever 6's offset, thereby avoids appearing dredging the phenomenon that pole 7 can not insert in the through-hole, thereby stability when having improved carriage release lever 6 and removing.

Preferably, in order to make the moving rod 6 move smoothly, the inner wall of the chute is coated with grease, so that the friction between the moving rod 6 and the chute is reduced, and the moving rod 6 moves more smoothly along the chute.

Preferably, in order to facilitate the insertion of the dredging rod 7 into the through hole, the end of the dredging rod 7 remote from the moving rod 6 is shaped like a hemisphere.

Preferably, in order to prevent the inner wall of the main body 1 from being corroded, the inner wall of the main body 1 is coated with an anti-corrosion zinc coating.

Preferably, the connecting rope 9 is made of a steel wire rope in order to prolong the service life of the connecting rope 9.

Preferably, to avoid separation of the connecting rod 14 from the groove, the groove is a dovetail groove.

Preferably, the motor 11 is a servo motor in order to make the motor 11 work accurately and stably.

Leading-in main part 1's of the cereal grain of rice inside through reaping apparatus 3, through the through-hole of fixed plate 5 for immature cereal grain falls the bottom in main part 1 through the through-hole, thereby has realized the function to the cereal grain screening, thereby has improved the quality that the rice was reaped. When the drying operation is performed, the motor 11 is controlled to be started, the second gear 12 is driven to rotate, the connecting rod 14 is driven to move back and forth through the driving rope 13, so that the ball screw bearing 16 is driven to move back and forth along the screw rod 17, the screw rod 17 rotates back and forth, the paddle 18 is driven to rotate in the fixing box 20, outside air enters the inside of the fixing box 20 through the air inlet pipe 19 and then is guided into the heating pipe 22 through the second through pipe 21, the temperature in the heating pipe 22 is heated through the self temperature of the motor 11 during the operation, the heated air is guided into the first through pipe 23 and then is guided into the inside of the heating pipe 25 through the first connecting pipe 24 and then is guided into the inside of the main body 1 through the second connecting pipe 26, so that hot air enters the inside of the main body 1, the heating and drying operation is performed on grains, and the quality of grains is prevented from being, the influence on subsequent discharging work is avoided, the reliability of the equipment is improved, meanwhile, the heat on the heating pipe 25 can be guided into the stirring plate 29, the temperature on the stirring plate 29 is increased, so that the heating and drying work can be carried out on grains through the stirring plate 29, the contact area is increased, the grains are heated more fully, meanwhile, when the second gear 12 rotates, the branch pipe 28 can be driven to rotate through the meshing of the first gear 27 and the second gear 12, the stirring plate 29 can be driven to rotate, the stirring plate 29 can be used for stirring work in the main body 1, the grains at all positions in the main body 1 can be dried, the drying range is expanded, the drying effect is improved, when the screw rod 17 rotates back and forth, the connecting disc 10 can be driven to rotate back and forth, the connecting rope 9 is lengthened or tightened, and the moving rod 6 moves up and down, make in the plug-in through-hole that dredging rod 7 is interrupted to dredge the work to the through-hole, reduce the probability that the through-hole is blockked up by ripe cereal grain, thereby avoid causing the influence to screening work, improved the reliability of equipment.

Compared with the prior art, this rice harvesting equipment with stoving function passes through screening mechanism, the function to the cereal screening has been realized, the quality that the rice was reaped has been improved, compare with current screening mechanism, this screening mechanism can also dredge work to the through-hole, reduce the probability that the through-hole is blockked up by ripe cereal, thereby avoid causing the influence to screening work, the reliability of equipment has been improved, construct through stoving, the function of drying to cereal has been realized, avoid cereal moist and influence cereal quality, also avoid causing the influence to subsequent work of arranging, the reliability of equipment has been improved, compare with current stoving mechanism, this stoving mechanism constructs as an organic whole link gear with screening mechanism, the practicality is higher.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
