A threshing cutter head on a corn automatic threshing device

Abstract

The invention discloses a threshing tool bit of an automatic corn threshing device. The threshing tool bit comprises a conical guide sleeve, a horizontal retaining ring is formed on the inner wall ofthe lower end of the guide sleeve, a vertical positioning shaft sleeve is inserted in the retaining ring, the upper end of the positioning shaft sleeve is fixedly welded to the inner wall of the guidesleeve, an annular retaining collar is formed on the outer wall of the middle of the positioning shaft sleeve and fixedly welded to the lower end face of the retaining collar, and the outer wall of the retaining collar is provided with an annular clamping groove. A magnetic steel sleeve is fixedly inserted to the positioning shaft sleeve on the lower side of the retaining collar. A conical rotating head is inserted in the positioning shaft sleeve, a vertical supporting shaft is formed at the lower end of the rotating head and fixed to a cross-shaped fixing support frame, and the outer end ofthe fixing support frame is fixed to the inner wall of the positioning shaft sleeve. A plurality of cutting blades are fixed to the outer wall of the rotating head, and upper lateral sides of the cutting blades are provided with oblique cutting edges. The threshing tool bit has advantages that corn kernel separation is realized while corncob cutting and crushing can be realized, and separated output of corncobs and corn kernels is realized.

Description

Technical field: [0001] The invention relates to the technical field of automation equipment, in particular to a threshing cutter head on an automatic corn threshing device. Background technique: [0002] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. At present, after corn threshing, its granules are easy to store or grind into corn flour, while traditional corn threshing generally uses manual threshing, especially for fresh corn, manual threshing is often used, but manual threshing is not only inefficient, but also labor-intensive . Therefore, it is proposed t...

Problems solved by technology

At present, after corn threshing, its granules are easy to store or grind into corn flour, while traditional corn threshing generally uses manual threshing, especially for fresh corn, manual threshing is often used, but manual threshing is not only inefficient, but also labor-intensive

Therefore, it is proposed to use mechanical automation equipment instead of manual detachment. At present, the threshing cutter on the automation equipment only realizes the detachment of corn grains, and cannot dissect the corn cobs. After the corn cobs are broken, they can be used as auxiliary feed additives. use, so that its automation equipment can be improved
