Abstract
Description
Technical Field
[0001] The embodiments of the present disclosure relate to the technical field of corn threshing, and in particular, to a microwave drying type corn thresher. Background Art
[0002] After the corn is harvested, it needs to be threshed to make canned corn, quick-frozen corn kernels, or stored as seeds. Only the corn kernels need to be preserved. When the corn kernels need to be stored for a long time or when there is a need to repel insects, the corn needs to be dried. In the prior art, there is a method of microwave heating and drying the threshed corn kernels through microwave technology. Microwaves can evaporate the moisture inside the corn and repel insects at the same time. The maturity of the corn kernels can also be adjusted according to needs, and the corn kernels can be processed in one step.

It is now proposed to combine the microwave heating and drying method of corn kernels with a thresher. Microwave heating treatment is performed before threshing the corn, so that the corn kernels are dried and hardened before threshing, which can increase the success rate of threshing and the integrity of the corn.

[0022] Example 1 like Figures 1 to 7As shown, it shows a microwave drying corn thresher in one embodiment of the present disclosure, including a base 1, a support frame 2, a microwave heating mechanism, a conveying and turning barrel 5, a threshing unit 6 and a corn collecting mechanism. The support frame 2 is fixedly connected to the base 1, and a feed port 3 and a sealing cover 4 are fixedly connected to one end of the support frame 2. The microwave heating mechanism is arranged on the support frame 2, and the microwave heating mechanism is used to heat the corn by microwaves. The conveying and turning barrel 5 is rotatably arranged on the base 1, the support frame 2 passes through the conveying and turning barrel 5, and the feed port 3 extends into the conveying and turning barrel 5. The microwave heating mechanism is arranged in the conveying and turning barrel 5. When the conveying and turning barrel 5 rotates, the microwave heating mechanism is fixed, the sealing cover 4 is rotatably connected to the conveying and turning barrel 5, the microwave heating mechanism passes through the sealing cover 4 and enters the conveying and turning barrel 5, and the feed port 3 is fixedly connected to the sealing cover 4. The threshing unit 6 is fixedly installed on the side of the base 1 away from the feed port 3. The threshing unit 6 is used to thresh the corn, the corn collecting mechanism is fixedly connected to the base 1, and the corn collecting mechanism is arranged between the threshing unit 6 and the conveying and turning barrel 5. The gathering mechanism is used to gather the corn in the conveying and turning barrel 5 to the threshing unit 6. A metal mesh 24 is fixedly connected to the base 1. The metal mesh 24 is arched and is sleeved on the conveying and turning barrel 5 and the threshing unit 6. The microwaves emitted by the microwave heating mechanism are blocked by the metal mesh 24 to prevent the microwaves from leaking. The metal mesh 24 can be made into a fully wrapped type, with openings left at the feed port 3 and the threshing unit 6. In this application, a microwave heating unit is set in the conveying and turning barrel 5. When the conveying and turning barrel 5 rotates, the corn is driven to rotate and pushed toward the threshing unit 6. During the movement, the corn is continuously heated by the microwave heating mechanism. The moisture content of the corn is reduced during the heating process. When the corn moves to the corn gathering mechanism, the dust and impurities that may exist in the corn are separated and then conveyed to the threshing unit 6 for threshing. Compared with the traditional mechanical method of corn threshing, the corn kernels are heated and dried by microwaves in advance, so that the corn texture is harder and the threshing is fuller during threshing, thereby improving the fullness of the kernels. At the same time, microwave heating can avoid local heating.
[0023] like Figures 1 to 5As shown, the microwave heating mechanism includes a disassembly track 7, a disassembly frame 8 and a microwave assembly. The disassembly track 7 is fixedly connected to the support frame 2, and the disassembly frame 8 is detachably slidably set on the disassembly track 7. There are multiple microwave assemblies, and multiple microwave assemblies are fixedly set on the disassembly frame 8. The disassembly track 7 and the microwave assembly are both located in the upper position of the conveying and turning barrel 5. The microwave assembly includes a microwave unit 9 and a radiation cavity 10. The microwave unit 9 is fixedly mounted on the disassembly frame 8, and the radiation cavity 10 is fixedly connected below the microwave unit 9. The radiation cavity 10 is set to a pyramid horn structure. The opening of the radiation cavity 10 is facing downward in the conveying and turning barrel 5. The magnetron in the microwave unit 9 emits microwaves downward through the radiation cavity 10 to heat the corn. The time of microwave heating of the corn can be controlled by controlling the rotation speed of the conveying and turning barrel 5. The microwave unit 9 can be easily replaced and maintained by disassembling the track 7. At the same time, heating methods such as infrared and hot air can be set for replacement. When there is less corn, traditional methods can be used for drying to increase the versatility of the equipment.
[0024] like Figures 2 to 5 As shown, a motor 11 and a bracket 12 are provided on the base 1, and the motor 11 is fixedly mounted on the base 1, and a plurality of brackets 12 are provided, and a plurality of brackets 12 are fixedly connected to the base 1, and a plurality of brackets 12 are respectively arranged on both sides of the conveying flip barrel 5, and a plurality of support wheels 13 are rotatably connected to the bracket 12, and the support wheels 13 are in contact with the conveying flip barrel 5, and the output end of the motor 11 is transmission-connected with the plurality of support wheels 13, and a plurality of conveying threads 14 are fixedly connected to the inside of the conveying flip barrel 5, and the side of the conveying thread 14 close to the sealing cover 4 is provided with an inclined section 15, and the thread at the inclined section 15 is inclined. When the corn enters the interior of the conveying flip barrel 5 through the feed port 3, it first contacts the inclined section 15, and two annular tracks are provided on the conveying flip barrel 5, and the support wheels 13 rotate the annular tracks. The output end of the motor 11 drives the support wheels 13 on the two brackets 12 to rotate through the transmission belt. The output end of the motor 11 drives the support wheels 13 to rotate, which can drive the conveying and turning barrel 5 to rotate. During the rotation, the conveying screw 14 rotates, and the corn rolls between the conveying screws 14. The conveying screw 14 pushes the corn to move in the conveying and turning barrel 5. During the movement of the corn, it is heated by the microwaves emitted by the microwave unit 9. A baffle is provided in the sealing cover 4. The baffle can block the corn that falls from the feed port 3 into the conveying and turning barrel 5 to prevent the corn from falling too quickly. After entering the conveying and turning barrel 5, the corn will fall on the inclined section 15. The width of the inclined section 15 is smaller to prevent the corn kernels with higher moisture from being squeezed too much during rotation, thereby preventing the corn kernels from being damaged.
[0025] like Figures 3 to 5As shown, the corn gathering mechanism includes a gathering plate 16, a fan 19 and a collecting port 20. The gathering plate 16 is fixedly connected to the base 1 and is in contact with the conveying and turning barrel 5.

The collecting port 20 is connected to the threshing unit 6. The collecting section 18 is set to an arc shape, and the blowing section 17 is set to a straight type. When the corn leaves the conveying and turning barrel 5 and falls on the blowing section 17, it is blown by the fan 19. The corn is blown and rolled onto the collecting section 18. At the same time, the dust and impurities therein are blown and separated by the collecting section 18. The corn slides up and down in the collecting section 18 to the collecting port 20 and is transported to the threshing unit 6. After the corn is transported to the gathering plate 16 through the conveying turning barrel 5, the corn moves to the blowing section 17 driven by the conveying screw 14. The fan 19 blows air on the corn. Some corn kernels may be separated from the corn cob in the conveying turning barrel 5, so that debris may be generated. When the debris moves to the blowing section 17, the fan 19 will blow the debris away in the collecting section 18, and the corn cobs and corn kernels will slide to the collecting port 20 and fall on the separation unit.
[0026] like Figure 6-Figure 7 As shown, a corn kernel opening 21 is provided on one side of the threshing unit 6 near the collecting port 20, a kernel outlet 1 22 is provided at the lower part of the threshing unit 6, and a kernel outlet 2 23 is provided on the side of the threshing unit 6. The existing mechanical threshing structure can be used for threshing in the threshing unit 6. A conveyor belt is provided on the threshing unit 6 to transport the corn cobs, and the corn cobs are transported to the mechanical threshing structure. The dried corn kernels can be fuller during mechanical threshing, and the corn kernels may be separated from the corn in the transporting turning barrel 5. After being transported to the gathering plate 16, the corn kernels can flow to the corn kernel opening 21 through the collecting port 20 and flow out through the kernel outlet 1 22. The corn kernels obtained after mechanical threshing are discharged through the kernel outlet 23.
[0027] In some examples, corn is added to the feed port 3, the corn contacts the baffle plate and falls into the conveying tilting barrel 5 and contacts the inclined section 15, the output end of the motor 11 drives the support wheel 13 to rotate, the support wheel 13 drives the conveying tilting barrel 5 to rotate, the corn rotates in the conveying tilting barrel 5, and is pushed by the conveying screw 14, the corn moves toward the gathering plate 16, the fan 19 blows away the impurities mixed in the corn, the corn falls on the threshing unit 6 through the collecting port 20, the corn kernels enter the corn kernel port 21 and are discharged through the kernel outlet 1 22, and after the corn is detached from the threshing unit 6, the corn kernels are discharged through the kernel outlet 2 23.
