Roller cutting type flos carthami filament harvesting device

Abstract

The invention provides a roller cutting type flos carthami filament harvesting device. The roller cutting type flos carthami filament harvesting device comprises a rack part, a cutting part and a negative pressure collecting part. The rack part is used for fixing all parts, a baffle rod is installed at the front end of a rack, the cutting part is installed at the rear end of the rack, and the negative pressure collecting part is installed at the rear end of the cutting part. In the forward moving process of the whole device, plants firstly pass through the baffle rod, if the height of flower balls is lower than the mounting position of the baffle rod, the flower balls successfully pass through the baffle rod to arrive at the cutting part, a rotary cutter completes cutting, if the height ofthe flower balls is higher than the mounting position of the baffle rod, the flower balls cannot pass through the baffle rod, at this moment, the device continues to move forwards, since the absoluteposition of the plants is unchanged, the relative height of the flower balls and the baffle rod is continuously reduced till the flower balls can successfully pass through the baffle rod to arrive atthe cutting part, and cutting and harvesting are completed. Cut filament is absorbed by a negative pressure collecting opening on the inner wall of the rotary cutter and is transferred to a collecting box through a pipe, and the whole harvesting work is completed. Through the sawtooth type rotary cutter, the device conducts cutting, the problem that the filament is difficult to feed can be effectively solved, large-scale blind harvesting is achieved, and the harvesting efficiency is improved.

Description

technical field [0001] The invention relates to a drum-cutting type safflower filament harvesting device, which can realize blind harvesting especially for situations such as missed harvesting and low efficiency in the large-area harvesting process, has better practicability and superiority, and belongs to agricultural Mechanical harvesting field. Background technique [0002] At present, in my country's safflower harvesting process, it is mainly based on manual harvesting, and various safflower filament harvesters also emerge in endlessly, but all fail to achieve the desired harvesting effect. The reason for the analysis is that the current harvesting devices are mainly cutting or pulling types. During the process of harvesting safflower filaments, these devices have difficulties in feeding filaments, serious missed harvesting, and the collection process is cumbersome after harvesting. Large-scale continuous picking and so on. The present invention solves the problem of d...
