Abstract

An air suction cutting type safflower filament harvesting device comprises a slitter part, a picking head part, a knife head part and a negative pressure collection box part. The slitter part includes the slitter and the slitter fixing frame, which is mainly used for combing the flower bulbs, gathering the flower bulbs at different positions in different tracks, and preparing for the picking head to pick the filaments. The picking head part includes the picking head and the suction port, which mainly realizes the arrangement and collection of filaments. The negative pressure field formed by the fan in the picking head is used to suck the surrounding filaments into the pipe of the picking head, so that the filaments drive the flower balls close to the picking head. The pipe rotates. The cutter head part includes fixed teeth, movable teeth and a fixed frame, which are used to cut a part of the filament pulled out by the flower ball under the action of the blocking rod, and complete the cutting process of the filament. The negative pressure collection box part mainly includes a collection box, a fan and a collection pipe. The collection box is used to collect the cut filaments, and the fan is used to generate a negative pressure airflow field. The device integrates the feeding, cutting and collecting of filaments, which can effectively solve the problems of difficulty in feeding filaments and improve harvesting efficiency.

Description

An air suction cutting type safflower filament harvesting device

technical field

The invention relates to an air-suction cutting type safflower filament harvesting device, which is particularly suitable for difficult filament feeding and low harvesting efficiency, has good practicability and superiority, and belongs to the field of agricultural machinery harvesting.

Background technique

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, which have difficulties in feeding the filaments during the harvesting process of safflower filaments, and the collection process is cumbersome after harvesting. The invention effectively solves the problems of difficulty in feeding filaments and cumbersome collection of filaments after harvesting by means of air suction and cutting.

Contents of the invention

The purpose of the present invention is to overcome the problems existing in the prior art, such as difficulty in feeding filaments during harvesting, complicated collection process after harvesting, low harvesting efficiency and the like.

To achieve the above objectives, the technical solution of the present invention is: an air suction cutting type safflower filament harvesting device, which mainly includes a slitter part, a picking head part, a cutter head part and a negative pressure collection box part.

During the harvesting process of safflower filaments, the curds enter from the slitter, and the slitter classifies and gathers the curds in different positions in different tracks, and arranges them in sequence in order to prepare for the picking head to pick the filaments. The picking head is located at the rear and upper part of the slitter, and the negative pressure generated by the fan is used to form a negative pressure airflow field in the picking head pipe, so that the filament enters the picking head under the action of the air flow, because the diameter of the flower ball is larger than the diameter of the picking head pipe , the curd will not enter the picking head pipeline. The filament drives the flower ball to rotate under the action of the airflow field. When the flower ball moves to the position of the stop rod, the flower ball starts to move away from the pipe of the picking head under the action of the stop rod.

The cutter head part is located between the blocking rod and the picking head pipe. When the flower ball touches the blocking rod, the filament is pulled out of the pipe part under the action of the flower ball. Under the action, the filaments are cut off, and under the action of the negative pressure airflow field, along the pipes of the picking head, the trachea enters the filament collection box to complete the whole harvesting process.

The picking head device adopts a disc-type design, which can be rotated for continuous picking. The picking head pipes are evenly distributed on the disc, and the design of the semicircular air suction port reduces the loss of the airflow caused by the unworking picking head pipes above, improving The effect of the negative pressure airflow field of the working picking head pipeline on the filament is realized, which is beneficial to the feeding of the filament.

Compared with prior art, the beneficial effect of the present invention is:

By using the combination of air suction and cutting, and using the force of the negative pressure airflow field in the pipe of the picking head on the filaments, the problem of difficulty in feeding the filaments can be effectively solved. Under the action, it enters the collection box along the pipeline, and the picking and collection are completed synchronously, which solves the problem of cumbersome collection of filaments after harvesting in the later stage.

detailed description

The invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1, a kind of suction cutting type safflower filament harvesting device. During the forward movement of the whole machine, the bouquet enters the slitting device 5, and under the action of the slitting device 5, the bouquets are gathered in different tracks, located on the picking head pipe on the right side cover plate 8 of the picking head Directly above. The blower fan 18 generates air flow, and a negative pressure airflow field is formed in the picking head pipeline on the right side cover plate 8 of the picking head connected to it. Inside the pipeline of the upper picking head. The picking head rotates under the action of the sprocket 1, and the filament, under the action of the airflow field, clings to the picking head pipe on the right side cover plate 8 of the picking head, driving the flower ball to rotate. When the flower ball moved to the stop bar 16, the flower ball pulled out a part of the filament from the picking head pipeline on the right side cover plate 8 of the picking head under the action of the stop bar 16. Under the effect of connecting rod 12, do reciprocating motion, cooperate with cutter head fixed tooth 13, finish the cutting work to filigree. The cut filigree is in the pipe of the picking head on the right side cover plate 8 of the picking head. Due to the effect of the continuous negative pressure airflow field, it passes through the suction port 11, the suction port connector 10, and the air collecting pipe to the collection box 9 to complete the collection of the whole set of filaments. process.
