Seedling separation and seedling taking assembly of artemisia selengensis cutting machine

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a seedling separation and seedling taking assembly of an artemisia selengensis cutting machine. The seedling separation and seedling taking assembly comprises a seedling box, a seedling separation device, a seedling taking device, a crank and rocker mechanism, a machine rack and the like. Fixed rollers in the seedling separation device is driven by an external driving force to do rotational motion to form a seedling taking waiting zone; seedling stalks enter the seedling taking waiting zone under the actions of gravity and disturbance of the fixed rollers; under the matching effect of the seedling taking device, air tap devices enter the seedling taking waiting zone to adsorb and take away individual seedling stalks; movable roller devices close a seedling taking opening under the action of tension springs to complete individual seedling separation. After the air tap devices in the seedling taking device adsorb the seedling stalks, the seedling stalks are transferred under the action of the crank and rocker mechanism so as to complete the process of taking seedling repeatedly. According to the invention, through the rotation of the fixed rollers, a seedling outlet is prevented from being blocked due to interaction of the seedling stalks and mechanisms inside the body of the seedling box; the air tap devices in the seedling taking device are used for adsorbing seedlings, so that posture correction of the seedling stalks is realized, and damage to materials is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a device for separating and picking seedlings of an Artemisia chinensis cutting machine, which can realize the separation and picking of individual cutting stalks of Artemisia chinensis cuttings. Background technique [0002] Artemisia annua is a perennial herb belonging to the genus Artemisia in the family Asteraceae. The seeds, roots and stems of Artemisia quinoa can be propagated. As early as the Ming Dynasty, the citizens of Nanjing began to eat wild Artemisia arborescens. Artemisia quinoa is rich in selenium, zinc, iron and other trace elements. It is eaten with tender stems. It is crisp, tender, spicy and unique in flavor. It is a well-known excellent vegetable. [0003] Artemisia quinoa is a very advantageous economic crop. In the early 1990s, people tried artificial cultivation of Artemisia quinoa, which was widely distributed in Northeast China, North C...

Problems solved by technology

[0004] The planting and production of Artemisia arborescens includes cultivation of Artemisia annua seedlings, production of cutting stalks, soil preparation, field cuttings, fertilization and many other operations. Among them, only the land preparation has realized mechanical operations, and the other links are completed manually, which is low in efficiency, high in cost, and labor-intensive. For example, in the cutting operation process, manual cutting is carried out according to the spacing between plants of 3-4cm and row spacing of 4-5cm. One mu of field requires a strong laborer to work for 3 days.

At present, there is a lack of specialized planting machinery for Artemisia sinensis. Due to the special physical characteristics of the stalks of Artemisia adenosomiasis, for example, the stalks of Artemisia arvensis are bare stalks, with neither roots nor branches. Planting machinery for other crops cannot be used for cuttings of Artemisia arvensis

[0005] Separation and picking of seedling stalks is a necessary link in the implementation of mechanical cuttings of Artemisia sinensis. In current transplanting machines, this link is mainly manual work, which has high labor intensity and low operating efficiency; the existing cutting machines for seedling separation and picking The technology generally has problems such as easy damage to seedlings, high labor consumption, and relatively low efficiency.

For example, when the semi-automatic vegetable transplanter is working, the seedlings in bundles, rows, and bundles are manually divided into individual plants by trained seedling-carrying personnel and put into conveyor belts, chain clips, seedling guide tubes, etc., which are done mechanically. Cutting, or manually inserting seedlings directly into the compartment surface; when pot seedling transplanting machinery is working, seedling separation, seedling picking, and seedling throwing are all manual operations; some models use automatic feeding mechanisms, whether manual or automatic , the process of taking seedlings from pot seedling trays and throwing seedlings requires one-to-one correspondence, and it is difficult to improve productivity and cannot meet large-scale transplanting and planting

The utility model patent "seedling separation machine" (patent number: 201020572785.7, announcement number: CN201813713U) mainly separates the seedling body through the seedling clamp, that is, the device directly contacts the seedling body rigidly, and directly picks up crops of different shapes, which inevitably causes The phenomenon of seedling injury occurs, and it is only suitable for the separation of seedlings of plants such as asparagus, river mud, and kelp

The utility model patent "an automatic seedling sorting machine" (patent number: 200920173013.3, announcement number: CN201467673U) uses the secondary seedling box to classify the shape and size of the seedlings, and does not realize the separation of single seedlings
