Abstract

A profiling air suction cutting type safflower silk harvesting device comprises a frame part, a profiling cover part, a cutting part and a negative pressure collection box part. The frame part is used to fix the parts, the profiling cover is installed at the front end of the frame, the cutting part is installed above the profiling cover, the air absorption collection port is installed at the working position of the cutting part, and the negative pressure collecting part is installed above the frame. During the forward movement of the whole device, the bouquet first touches the profiling cover, and under the action of the air pressure in the air absorption collector, the bouquet enters the profiling cover, and the curd is temporarily fixed under the action of the air pressure and the profiling cover. The crescent-shaped reciprocating cutter realizes the cutting operation of the fed filaments, and the cut filaments enter the negative pressure collection box under the action of negative pressure to complete the whole set of filament harvesting process. The device uses air suction and profiling hood to assist filament feeding, which can effectively solve the problems of severe bouquet shaking and difficult filament feeding, realize large-scale blind harvesting, and improve harvesting efficiency.

Description

A profiling air suction cutting type safflower silk harvesting device

technical field

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

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 cumbersome and cannot be picked continuously on a large scale. The invention solves the feeding and fixing problems of filaments by using air suction and profiling cover, and solves the problem of filament gathering in the process of cutting filaments by using crescent-shaped reciprocating cutter cutting, and realizes feeding, cutting and collecting filaments.

Contents of the invention

The purpose of the present invention is to overcome the problems in the prior art such as severe bouquet shaking, difficulty in feeding filaments, low picking efficiency and the like in the process of picking large-scale filaments.

To achieve the above objectives, the technical solution of the present invention is: a profiling air suction cutting type safflower silk harvesting device, which mainly includes a frame part, a profiling cover part, a cutting part and a negative pressure collection box part.

During the harvesting of safflower filaments, the curd enters from the front of the frame and first hits the profiling cover installed on the frame. The inner side of the profiling cover and the air absorption collection port form a negative pressure vacuum under the action of the fan, and the flower balls enter the profiling cover under the action of air suction. The profiling cover is conical, similar to the shape of the curd. Under the action of air suction, the filament enters the cutting position, and the curd is temporarily fixed under the action of the negative pressure and the profiling cover, waiting for the filament to be cut. The cut filaments are collected under negative pressure into the negative pressure collection box installed above the frame to complete the whole harvesting process.

The profiling cover and the complete set of cutting devices matched with it are installed on the frame in three layers, covering the distribution of curds of a single plant. In the harvesting operation, the precise positioning of the filaments is not required manually, and the filaments can be accurately positioned. Large-scale mechanized blind mining.

The crescent-shaped cutting tool refers to the use of the slider crank mechanism to cut the filaments. The edge of the knife is crescent-shaped, which aims to realize the gathering and cutting of the filaments and improve the success rate of cutting the filaments that have entered. The cutting knives of each row of profiling hoods are controlled by a single motor, and the opening and closing times of the cutting knives on adjacent profiling hoods are different, thus effectively avoiding system instability caused by reciprocating knives.

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

The combination of profiling cover and air suction effectively solves the serious problem of bouquet shaking in the harvesting process and improves the success rate of filament feeding. By using crescent-shaped cutters, the filaments are gathered and cut, which improves the efficiency of the device. Extraction rate.

Detailed ways

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

Referring to Fig. 1, Fig. 2, a kind of profiling air suction cutting type safflower filament harvesting device. When the whole machine is moving forward, the bouquet first touches the profiling cover (4), and under the action of the air pressure in the air absorption collection port (2), the bouquet near the profiling cover (4) enters the profiling cover (4), under the joint action of the air suction and the profiling cover (4), the temporary fixation of the curd is realized. The motor (8) drives the eccentric disc (9) to make a circular motion, so that the upper connecting rod (6) and the lower connecting rod (10) connected to it drive the upper blade (11) and the lower blade (12) to reciprocate, and the The entered filaments can be cut and harvested. The cut filaments enter the negative pressure collection box (3) above the frame (1) under the action of air suction to complete the whole set of filament harvesting process.
