Circulation lifting and screening type multistage grain crushing device

Abstract

The invention relates to the field of agricultural production, and particularly relates to a circulation lifting and screening type multistage grain crushing device. The device comprises a vertically-arranged supporting mounting cylinder, the lower end of the supporting installation cylinder is provided with a conical surface guide cylinder, a discharging hole is formed in the lower end of the conical surface guide cylinder, a plurality of supporting mounting columns are arranged at equal angles on the outer side of the conical surface guide cylinder, a driving installation cover is verticallyarranged right above the supporting installation cylinder, and the outer ends of the feeding mounting columns are connected with the upper end of the supporting mounting cylinder. Through the multi-motor planetary gear driving structure, the transmission efficiency of the device is high, the requirement for motor selection is reduced, two-stage crushing is realized through the synchronous drivingstructure, so that the transmission efficiency of the device is high, the crushing quality is good, the crushing quality of the device is further improved through the structural design of circulatingscreening and lifting, and the processing quality of cereals is remarkably improved.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a circulating lifting and screening type multi-stage grain crushing device. Background technique [0002] Cereals mainly refer to the seeds of gramineous plants. The nutrient content of cereals may vary greatly due to different types, varieties, origins, growth conditions and processing methods. The current grain crushing device is not enough to crush grains. The broken grains cannot be quickly dried, and the drying process mostly adopts hot air drying, which cannot realize the recycling of hot air during the drying process, and is not conducive to the rapid drying of grains. [0003] The Chinese patent (publication number CN108452927A) discloses an energy-saving grain crushing air dryer. Although it can be dried, it has defects in the design of the crushing drive structure, the crushing structure, and the processing quality efficiency of crushing. SUMMARY OF THE INVENTIO...

Problems solved by technology

[0002] Cereals mainly refer to the seeds of gramineous plants. Due to the different types, varieties, origins, growth conditions and processing methods of cereals, the nutrient content of cereals varies greatly. The crushed grain crumbs cannot be dried quickly, and the drying process mostly uses hot air drying, and the hot air cannot be recycled during the drying process, and it is also not conducive to the rapid drying of the grain crumbs

[0003] Chinese patent (publication number CN108452927A) discloses an energy-saving grain crushing air dryer. Although it can be dried, it has defects in the design of the driving structure of the crushing, the crushing structure, and the quality and efficiency of the crushing process.
