Profiling air suction cutting type saffron thread harvesting device

Abstract

The invention provides a profiling air suction cutting type saffron thread harvesting device, which comprises a machine frame part, a profiling cover part, a cutting part and a negative pressure collecting box part, wherein the machine frame part is used for fixing various components; the profiling cover is arranged at the front end of the machine frame; the cutting part is arranged above the profiling cover; an air suction collecting opening is formed in the operation position of the cutting part; the negative pressure collecting part is arranged above the machine frame. In the process that the whole device forwards moves, a flower ball firstly touches the profiling cover; under the effect of the air pressure in an air suction collecting opening, the flower ball enters the profiling coverand realizes the temporary fixation of the flower ball under the effects of the air pressure and the profiling cover. The cutting operation on the fed flower threads can be realized through a crescent reciprocating cutter; the cut flower threads enter a negative pressure collecting box under the negative pressure effects; the whole set flower thread harvesting process can be completed. The flowerthread suction is assisted by using the air suction and the profiling cover; the problems of serious flower ball shaking and flower thread feeding difficulty can be effectively solved; the large-scale blind picking is realized; the harvesting efficiency is improved.

Description

technical field [0001] The invention relates to a profiling air-suction cutting type safflower filament harvesting device, which can realize blind harvesting and reduce labor costs especially for the severe bouquet shaking and difficulty in feeding filaments during the large-area picking process. Good practicability and superiority belong to the field of agricultural machinery harvesting. Background technique [0002] At present, in the process of harvesting safflower in my country, manual harvesting is the main method, and various machines for harvesting safflower filaments emerge in an endless stream, but all fail to achieve the desired harvesting effect. The reason for the analysis is that the current harvesting devices are mainly cutting type or pulling type. During the process of harvesting safflower filaments, these devices have serious bouquet shaking, difficulty in feeding filaments, serious missed harvesting, and collection after harvesting. The process is cumberso...
