DETAILED DESCRIPTION

[0024] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0025] A self-priming corn thresher, such as Figure 1-4 As shown, it includes: a base 1, a thresher 2, an air lock 3, a conveying auger 4, a conveying pipe, a first telescopic pipe 12, a suction port 13 and an exhaust fan 5. The thresher 2 is provided on the base 1. The feed port of the thresher 2 is connected to the outlet of the air lock 3. The inlet of the air lock 3 is connected to the discharge port of the conveying auger 4. The air lock 3 is a star-shaped discharger, which conveys the corn of the conveying auger 4 to the thresher 2 through the air lock 3. The air lock 3 can prevent the wind force of the exhaust fan 5 from reaching the thresher 2 through the auger and affecting the normal operation of the thresher 2. The feed hopper 2 of the conveying auger 4 2 is connected to the conveying pipe, and one end of the conveying pipe away from the conveying auger 4 is connected to the suction port 13 through the first telescopic tube 12. The distance between the suction port 13 and the corn can be adjusted by extending the first telescopic tube, so that the suction port 13 can suck the corn conveniently. An air outlet is arranged below the conveying auger 4, and the air outlet is connected to the exhaust fan 5 through a pipe. A screen is arranged on the air outlet. The wind force of the exhaust fan 5 transports the corn through the suction port 13 and the conveying pipe to the conveying auger 4, and then transports the corn to the air lock 3 through the conveying auger 4, and then falls into the thresher 2 from the air lock 3 for threshing.

[0026] The conveying auger 4 includes: a shell, a spiral blade, a rotating shaft, a motor, a screen and an air outlet. The shell is provided with a feed hopper 22, a discharge port and an air outlet. The rotating shaft is located in the middle of the shell. The feed hopper 22 and the discharge port are centrally symmetrical with the center point of the shell. The air outlet is located below the feed hopper 22. The rotating shaft is provided with a spiral blade. The screen is located at one end of the air outlet close to the rotating shaft. The rotating shaft is connected to the output end of the motor. The screen prevents corn from leaking out of the air outlet. During the operation of the conveying auger, the rotating shaft is first driven by the motor to rotate, and the rotating shaft drives the spiral blade to rotate. During the rotation, the spiral blade moves the corn from the feed hopper to the discharge port and enters the air lock.

[0027] like Figure 1-3 As shown, the conveying pipe is divided into: a first section conveying pipe 7, a second section conveying pipe 9, a third section conveying pipe 11, a first gear 6, a first transmission gear 17, a first hydraulic motor 16, a first bearing 21, a second telescopic pipe 8, and a corner pipe 10. The first section conveying pipe 7 is connected to the feed hopper 22 of the conveying auger 4. The first section conveying pipe 7 and the shell of the conveying auger 4 are perpendicular to each other. The outer wall of the first section conveying pipe 7 near one end of the conveying auger 4 is connected to the inner ring of the first gear 6. The first gear 6 is connected to the first transmission gear 17. The first transmission gear 17 is connected to the output end of the first hydraulic motor 16. The inner wall of the first section conveying pipe 7 near one end of the conveying auger 4 is fixedly connected to the outer ring of the first bearing 21. The inner ring of the first bearing 21 is fixedly connected to the feed hopper 22 through a connecting plate 26. The first hydraulic motor 16 is fixed to the outer ring of the conveying auger 4. At the top, the first section of the conveying pipe 7 and the second section of the conveying pipe 9 are connected by the second telescopic pipe 8, and a hydraulic cylinder 19 is also arranged between the first section of the conveying pipe 7 and the second section of the conveying pipe 9, and the cylinder body of the hydraulic cylinder 19 is hinged to the first section of the conveying pipe 7 by a pin, and the push rod of the hydraulic cylinder 19 is hinged to the second section of the conveying pipe 9 by a pin, so that the angle between the first section of the conveying pipe 7 and the second section of the conveying pipe 9 is adjusted by the extension or shortening of the hydraulic cylinder 19, thereby affecting the third section of the conveying pipe 11 to drive the suction port 13 to move up and down, the third section of the conveying pipe 11 and the second section of the conveying pipe 9 are connected by a corner pipe 10, and the third section of the conveying pipe 11 and the first section of the conveying pipe 7 are parallel to each other, and the end of the third section of the conveying pipe 11 away from the corner pipe 10 is connected to the first telescopic pipe 12, so that the third section of the conveying pipe 11 can be disposed in the direction of the ground to facilitate suction. When the angle needs to be rotated, the first hydraulic motor 16 can be turned on. The first hydraulic motor 16 drives the first gear 6 to rotate through the first transmission gear 17, so that the first gear 6 drives the first section of the conveying pipe 7 to rotate, and the first section of the conveying pipe 7 can drive the conveying pipe as a whole to rotate, thus completing the angle movement.

[0028] like Figure 4As shown, the suction port 13 is provided with a second hydraulic motor 14, a second transmission gear 25, a second gear 24, a second bearing 23, and a material-pick-up plate 15. The output end of the second hydraulic motor 14 is connected to the second transmission gear 25, the second transmission gear 25 is meshed with the second gear 24, the inner ring of the second gear 24 is fixedly connected to the outer ring of the second bearing 23, the inner ring of the second bearing 23 is fixedly connected to the suction port 13 through a connecting plate 26, and one end of the second gear 24 away from the first telescopic tube 12 is fixedly connected to the material-pick-up plate 15. The second hydraulic motor 14 is used to drive the second transmission gear 25 to rotate, the second transmission gear 25 drives the second gear 24 to rotate, the second gear 24 drives the material-pick-up plate 15 to rotate, and after the material-pick-up plate 15 pokes the corn, it is convenient for suction to be applied to the corn.

[0029] The thresher 2 includes: a threshing chamber, a rotating shaft, a motor, a threshing rod, and a filter plate. The motor is located at one end of the threshing chamber, and the output end of the motor is connected to the rotating shaft. The rotating shaft is provided with a threshing rod, and a filter plate is provided below the threshing rod. The filter plate is provided with a plurality of filter holes, and corn kernels flow out through the filter holes. A guide plate is provided below the filter plate, and the grain outlet is located at the bottom of the thresher 2. The guide plate guides the corn kernels to flow to the grain outlet. The end of the rotating shaft away from the feed port is provided with a core outlet. After threshing, the corn cob is discharged from the core outlet. During the rotation of the rotating shaft, the threshing rod is driven to collide with the corn, so that the corn kernels on the corn can be removed from the corn cob. Finally, the corn kernels enter the guide plate through the filter plate, and flow to the grain outlet through the guide plate for discharge.

[0030] like Figure 1 As shown, a moving wheel 18 is provided under the base 1, and a connecting handle 20 is provided at one end of the base 1. The base 1 is connected to a tractor head through the connecting handle 20, and the tractor head pulls the base 1 to move the whole body.

[0031] The base 1 is also provided with a hydraulic pump, which provides power for the first hydraulic motor 16 , the second hydraulic motor 14 and the hydraulic cylinder 19 .

[0032] In the technical solution of the present application, the tractor head is first connected with the connecting handle 20 on the base 1 to pull the thresher 2 as a whole to the pile of corns. First, the first hydraulic motor 16 is turned on. The first hydraulic motor 16 drives the first gear 6 to rotate through the first transmission gear 17, so that the first gear 6 drives the first section of the conveying pipe 7 to rotate, and the first section of the conveying pipe 7 can drive the conveying pipe as a whole to rotate. During the rotation, the suction port 13 is aligned with the corn pile, so that the preliminary alignment of the suction port 13 is completed. Secondly, the hydraulic cylinder 19 is turned on again, and the angle between the second section of the conveying pipe 9 and the first section of the conveying pipe 7 is adjusted by extending or shortening the push rod of the hydraulic cylinder 19, thereby driving the second section of the conveying pipe 9 connected to the first section of the conveying pipe 7. The upper and lower positions of the suction port 13 are adjusted, and the suction port 13 is brought close to the corn. Finally, if the suction port 13 is still not aligned with the corn, fine-tune it through the first telescopic tube 12 to make the suction port 13 close to the corn, and then turn on the exhaust fan 5 and the second hydraulic motor 14. The second hydraulic motor 14 drives the second transmission gear 25 to rotate, and the second transmission gear 25 drives the second gear 24 to rotate. The second gear 24 drives the prying plate 15 to rotate. After the prying plate 15 pries the corn, the wind force of the exhaust fan 5 sucks the corn into the conveying pipe, and finally falls into the conveying auger 4, and the corn is transported to the air lock 3 through the conveying auger 4, and then the corn is transported to the thresher 2 through the air lock 3, and finally the threshing work is completed by the thresher 2.

[0033] In this way, during the entire feeding and threshing process, the wind force of the exhaust fan 5 is used to suck all the corn into the conveying pipe, and then transported to the conveying auger 4 through the conveying pipe. The auger and the air lock 3 are used to transport the corn to the thresher 2, so there is no need for manual shoveling of corn to feed the corn, thereby reducing the labor intensity.

[0034] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
