Technical Field

The invention relates to agricultural machinery, in particular to a clamping and conveying device used in garlic harvesting and a garlic harvester provided with the clamping and conveying device.

Background

Garlic is an economic crop widely planted in China, and the existing garlic harvesting machines mainly comprise two types, one type is a simple digging machine, the other type is a combined harvesting machine adopting a clamping and pulling transmission structure, wherein the clamping and pulling transmission structure is used for vertically clamping two sides of a garlic plant in a natural growth state and then horizontally lifting, and the structure is more suitable for harvesting garlic planted in a wide row spacing and not laid down, and when the row spacing of the garlic is narrow, the clamping and transmission of two adjacent rows are interfered, for example, patent application numbers FR8907373, CN2010102048914, CN202010722769X and the like are adopted; when crops such as cotton, hot pepper, corn and the like are interplanted before garlic is harvested, the interplanted crops are damaged by the conventional clamping and conveying mechanism, so that the garlic is not suitable for mechanical harvesting of the garlic in which other crops are interplanted; in addition, when abnormal growth states such as lodging and the like occur to garlic plants, the phenomenon of clamping omission often occurs to the combined harvester. The main reason for these technical problems is that the revolving plane of the clamping and conveying mechanism is perpendicular to the planting plane of the harvested garlic, the space occupied between two rows is the largest under the condition that the width of the clamping and conveying mechanism is the same, and meanwhile, the stalks of the fallen garlic are difficult to automatically enter the clamping and conveying mechanism. Due to the defects of the existing garlic harvesting machine, the manual harvesting proportion is still very high, the harvesting efficiency is low, and the labor intensity is high.

Disclosure of Invention

The invention aims to solve the technical problems in the existing garlic harvester, provides a garlic clamping and conveying mechanism suitable for narrow row spacing and interplanting of other crops, and is beneficial to clamping and conveying of lodging garlic.

In order to solve the problems, the technical scheme adopted by the invention is as follows: a garlic clamping and conveying device comprises a clamping and conveying mechanism arranged on a rack, wherein an angle between a clamping rotary plane formed by the clamping and conveying mechanism and a garlic planting plane is more than or equal to zero degrees and less than ninety degrees. The clamping rotary plane is a plane on which a track for clamping garlic stalks to rotate for a circle at a certain point on the clamping and conveying mechanism is located. The garlic planting plane is a plane formed by a line of garlic and a line formed by a growth line of garlic plants, and is generally a plane perpendicular to the ground through a line of garlic plants. When the included angle between the clamping rotary plane and the garlic planting plane is zero degree, the clamping rotary plane is superposed or parallel to the garlic planting plane, and the clamping conveying mechanism occupies the least transverse space between two adjacent rows of garlic and is most suitable for harvesting garlic with narrow row spacing or interplanting of other crops; when the included angle between the clamping rotary plane and the garlic planting plane is gradually increased, the transverse space occupied by the corresponding clamping conveying mechanism is also gradually increased, and when the included angle between the clamping rotary plane and the garlic planting plane is equal to ninety degrees, the garlic planting plane is the existing clamping conveying mechanism, and the occupied transverse space is the largest, so that the garlic planting mechanism is most unfavorable for harvesting narrow row spacing or interplanting garlic.

As a preferred scheme of the invention, the front end of the clamping and conveying mechanism is provided with a guide mechanism which enables garlic plants to fall to the clamping and conveying mechanism.

As a preferable scheme of the present invention, the clamping and conveying mechanism is matched with a garlic root hair and stem cutting device installed at the rear end thereof so as to cut off the garlic root hair and stem.

The clamping and conveying device further comprises a rack and a transmission mechanism so as to transmit power to the clamping and conveying mechanism.

Compared with the prior art, the technical scheme of the invention has the beneficial effects that:

1) the garlic harvester adapts to different garlic harvesting conditions by changing the included angle between the clamping rotary plane and the garlic planting plane, particularly reduces the transverse occupied space to the maximum extent when the included angle between the two planes is zero, is suitable for harvesting narrow row spacing or interplanting garlic, and fills up the mechanized harvesting of garlic interplanting other crops in China;

2) compared with the existing clamping and conveying mechanism, the clamping and conveying mechanism is easier to clamp the stalks of the fallen garlic and is more beneficial to harvesting the fallen garlic;

3) the garlic combine harvester is compact in structure, a plurality of clamping and conveying mechanisms can be installed on one garlic combine harvester, the distance between every two adjacent clamping and conveying mechanisms can be adjusted according to planting conditions, and the garlic combine harvester is high in adaptability.
