Abstract

A continuous cutting type safflower harvesting device mainly comprises a frame part, a profiling picking device and a negative pressure collecting part. The frame part is used for fixing each part, and two profiling picking devices distributed in the front and back are arranged below the frame, and the negative pressure collecting box is arranged above the frame. During operation, the device moves forward, and under the effect of the rotating motor, the copying picking device rotates to cover the whole plant ball, the cut filaments enter the copying flower collecting opening under the negative pressure effect, the rotary knife finishes cutting, and the cut filaments enter the collecting box along the pipeline under the negative pressure effect to finish the collection of the filaments. The device utilizes rotatory profile modeling to pick the device, accomplishes the full coverage to the safflower plant, can realize gathering completely in succession the filament.

Description

Continuous cutting formula safflower harvesting device

Technical Field

The utility model relates to a continuous cutting formula safflower harvesting device especially picks the silk feeding difficulty that the in-process appears, the ball-flower damage is serious, pick the condition such as process discontinuity to the silk, has better practicality and superiority, belongs to agricultural machine results field.

Background

At present, in the safflower harvesting process in China, manual harvesting is mainly used, and various safflower filament harvesting machines are infinite, but all the safflower filament harvesting machines fail to achieve ideal harvesting effects. The analysis reason is that the current harvesting device is mainly of a cutting type or a drawing type, the problems of difficult filament feeding, serious damage to flower balls, incomplete picking, discontinuous harvesting process and the like exist in the process of harvesting safflower filaments in the device, and the precise positioning of the filaments needs to be manually realized. The utility model discloses utilize gas suction hood and negative pressure to solve the silk feeding problem, utilize two sets of rotatory profile modeling to pick the device and accomplish fully picking the continuity of safflower plant, can improve whole trunk and pick efficiency.

Disclosure of Invention

The utility model aims at overcoming the problems of difficult feeding of the filament, serious damage of the ball of the flower, discontinuous picking process, incomplete picking and the like in the filament picking process in the prior art.

In order to achieve the above purpose, the technical solution of the utility model is that: a continuous cutting type safflower harvesting device mainly comprises a frame part, a profiling picking device and a negative pressure collecting part.

In the process of harvesting the safflower filaments, the two profiling picking devices arranged front and back pick single-row safflower plants in sequence, the device advances forwards, the profiling picking devices slowly rotate under the action of the rotating motor to complete full-coverage picking of the safflower plants, and the whole device continuously moves forwards during working, so that continuous and full picking can be realized. The picked filaments enter the collecting box along the pipeline under the action of negative pressure in the air suction port, and the whole picking process is completed.

The profiling picking device comprises an air suction cover and a cutting part, and a profiling flower collecting opening is arranged on the inner wall of the air suction cover, so that the filaments smoothly enter the cutting part, the flower balls are left on the outer side, the damage of the flower balls is avoided, the shake of the flower balls in the cutting process is reduced, and the net picking rate of the filaments is improved. The cutting part comprises a cutting motor, a movable knife arranged on the rotating frame and a fixed knife arranged on the profiling flower collecting opening, the fixed knife and the movable knife are designed to be tightly attached to the inner wall of the air suction cover, the length of the picked filament is increased as much as possible, and the damage to the filament is reduced.

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

through the mode that uses air suction hood and negative pressure to combine, solved the difficult, serious scheduling problem of pompon damage of filament feeding, utilize two rotatory profile modeling harvesting devices to realize fully picking the continuity of safflower plant, improved the filament and picked efficiency.

Shown in the figure: the device comprises an air suction cover, a machine frame, a collecting box, a chain, an air suction port, a rotating motor, a double-row chain wheel, a cutting motor, a fixed knife, a moving knife holder and a profiling flower collecting opening, wherein the 1 is the inner wall of the air suction cover, the 2 is the outer wall of the air suction cover, the 3 is a thrust bearing, the 4 is the machine frame, the 5 is the collecting box, the 6 is the chain, the 7 is the air suction port, the 8 is the rotating motor.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, fig. 2 and fig. 3, a continuous cutting type safflower harvesting device. The device works continuously during working, the two profiling picking devices rotate at a low speed and pick safflower plants around the profiling picking devices. When picking the safflower plant, two profile modeling pick devices rotation around driving under the effect of rotating electrical machines (8), accomplish the comprehensive cover to the safflower ball, and the device lasts and gos forward, can realize continuous operation. The inner wall (1) of the air suction cover contacts the flower ball first, and the filament enters the profiling flower collecting opening (14) under the action of negative pressure in the air suction opening (7). A cutting motor (10) arranged on the inner side of the inner wall (1) of the air suction cover drives a movable knife rest (13) to rotate, and a movable knife (12) is arranged on the movable knife rest (13) and matched with a fixed knife (11) arranged on a profiling flower collecting opening (14) to cut the cut-up flower filaments. The cut filaments are conveyed to the collecting box through a pipeline under the action of negative pressure in the air suction port (7), and the processes of picking and collecting the safflower are finished.

The above description is only a preferred example of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
