The frame part is used to fix the parts, the drum cutting part is composed of a moving knife and a fixed knife, the moving knife is fixed on the main shaft, the profiling baffle is installed under the opening of the air suction hood, and the fixed knife is installed on the profiling baffle. During the harvesting operation, under the action of negative pressure in the air suction hood, the filaments enter the opening of the air suction hood wall, and under the action of air suction and the profiling baffle, the flower ball is temporarily fixed, and the moving knife passes through the main shaft The rotation and the fixed knife cooperate to complete the cutting process of the curd filaments, and the cut filaments are collected into the negative pressure collection box under the action of negative pressure to complete the harvesting process. The device uses the function of profiling baffle and air suction to fix the curd, which effectively solves the problem of severe curd shaking and difficulty in feeding filaments. The drum cutter is used to realize continuous cutting of filaments and improve picking efficiency.

Description

A profiling drum cutting type safflower harvesting device

technical field

The utility model relates to a profiling drum cutting type safflower harvesting device, especially aimed at the situation that the flower balls shake seriously and the filaments are difficult to feed in the process of picking the filaments, which is beneficial to the fixing of the flower bulbs and improves the cleaning rate of the filaments. The utility model has better practicability and superiority, and belongs 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 or pulling types. During the process of harvesting safflower filaments, these devices have serious bouquet shaking, difficulty in feeding filaments, and manual positioning of filaments is required. and so on. The utility model uses profiling baffles to strengthen the fixing of flower balls, solves the serious problem of flower ball shaking, uses the cutter installed on the drum and the air suction method to solve the problem of filament feeding, realizes continuous harvesting of filaments, and improves the quality of filament harvesting. net rate.

Contents of the invention

The purpose of the utility model is to overcome the problems in the prior art, such as severe bouquet shaking, difficulty in feeding filaments and high labor intensity, which occur in the process of picking filaments.

To achieve the above objectives, the technical solution of the present invention is: a profiling drum cutting type safflower harvesting device, which mainly includes a frame part, a drum cutting part and an air absorbing part.

During the harvesting process of safflower filaments, the flower ball enters from the front of the frame, and first hits the air suction hood. Under the action of negative pressure in the air suction hood, the filament enters the opening of the air suction hood wall. Go to the profiling baffle below the air suction hood, under the action of air suction and profiling baffle, the bouquet is temporarily fixed. The profiling baffle is in the shape of a curd, and aims to fix the curd by fixing multiple points of the curd, enhance the fixation of the curd, and improve the cleaning rate of the filament.

The drum cutting part is installed in the air suction hood. When the curd is temporarily fixed, the cutting of the filaments is realized under the action of the fixed knife and the moving knife. The cut filaments are sucked by air under the negative pressure. The collecting port is collected into the negative pressure collection box to complete the whole harvesting process. The moving knife is installed on the main shaft to realize continuous rotary cutting and improve the efficiency of picking filigree.

Compared with the prior art, the beneficial effects of the utility model are:

By using the combination of profiling baffle and air suction, the problem of serious bouquet shaking is solved, the problem of difficult feeding of filaments is solved by using the air suction cover, and the continuous cutting of filaments is realized by using the roller cutter, which improves the efficiency of filament picking .

Detailed ways

The utility model will be further described in detail below in conjunction with the description of the drawings and specific embodiments.

Referring to Fig. 1, a kind of profiling drum cutting type safflower harvesting device. When the whole machine is moving forward, the flower ball first touches the air suction cover (6), under the action of negative pressure in the air suction cover (6), the filament enters the opening of the air suction cover (6), and the flower ball moves At the position of the profiling baffle (7), under the effect of negative pressure in the profiling baffle (7) and the air suction cover (6), the curd is temporarily fixed. The fixed knife (13) is installed on the top of the profiling baffle (7), and works together with the moving knife (12) installed on the main shaft (10) to complete the cutting process of the fixed curd filaments. Under the action of negative pressure in the air suction hood (6), the cut filaments pass through the air absorption collection port (1) to the negative pressure collection box (4) to complete the entire cutting and collection process.

The above is only a preferred example of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model shall be included in this utility model. within the scope of protection of utility models.
