Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as Figure 1~5 As shown, the present invention includes a seed metering device housing 1, a seed metering device cover plate 2, a suction chamber housing 3, a seed metering disc 4, a seed guide impeller 5, a partition 6, a wear-reducing sealing ring 7 and an air nozzle 8 . The seed meter housing 1 and the seed meter cover plate 2 are fixedly snapped together to form a circular chamber, the suction chamber housing 3, the seed metering disc 4, the seed guiding impeller 5, the partition 6 and the wear-reducing sealing ring 7 set in the circular chamber.

[0020] The seed meter housing 1 includes an open circular cavity 11 made of circular steel plates, and a square body 12 is arranged on the top of the circular cavity 11 for easy hoisting. Both sides of the seed meter housing 1 are respectively provided with an adjusting plate 13, and the ...

Abstract

The invention relates to a pneumatic bucket wheel type precision corn seeder. The pneumatic bucket wheel type precision corn seeder is characterized in that: the pneumatic bucket wheel type precision corn seeder comprises a seeder housing, a seeder cover plate, a suction chamber shell, a discharge plate, a seed guide impeller, a partition and an antifriction seal ring; the suction chamber shell is of an annular structure, and is fixedly connected with the seeder housing, both the inner and the outer edges of the suction chamber shell outwardly extend, so that two circles of sidewalls are formed, a groove is formed between the two sidewalls, and the sidewall extending out of the outer edge is provided with a section of curved notch as an air opening; a plurality of discharge buckets are arranged at intervals on the circumference of the outer edge of the discharge plate, and each discharge bucket is provided with a section of air groove along the axial direction; the discharge plate and the suction chamber shell are fastened together, so that an annular air chamber is formed between the discharge plate and the groove of the suction chamber shell, and moreover, the sidewall extending out of the outer edge of the suction chamber shell is just fastened with the edge of the air groove of each discharge bucket; the seed guide impeller is fixedly connected with the discharge plate, and is partitioned by the partition; the antifriction seal ring is arranged between the discharge plate and the partition, and an air suction passage is formed between the antifriction seal ring and the air groove of each discharge bucket of the discharge plate.

Description

technical field [0001] The invention relates to a seed metering device in the field of agricultural machinery, in particular to a pneumatic spoon wheel type corn precision seed metering device. Background technique [0002] At present, the southwestern region of China is one of the dominant regions for corn planting, and its corn planting area and output account for about 30% of the total corn output and total area. However, because 90% of its land is distributed in hilly areas and plateaus, the slope of cultivated land is relatively large, and the plots are small and scattered, and the ground level difference is large. Large and neutral machines are basically unable to work in the field. Therefore, corn mechanization is sown in this area. develop slowly. The seed meter is the core part of the seeder, and its working performance directly affects the quality of corn machine sowing, and the power consumption is small, and it still has good seed metering performance under the ...
