The utility model realizes the cutting, extraction and throwing of the white asparagus by driving the movement of the harvesting end effector, thereby improving the harvesting efficiency of the white asparagus.

Description

End effector for harvesting white asparagus by drawing and cutting

Technical Field

The utility model belongs to the agricultural machine field relates to the end effector that gathers of the white asparagus of stretch-cutting formula to this realization is to the root of cutting of white asparagus, is pulled out, is thrown and is put the operation, and need not to dig and backfill.

Background

The asparagus is a high-nutrition health-care vegetable which is popular with consumers. Asparagus is named as asparagus, and is divided into white asparagus and green asparagus, wherein branches and leaves of the asparagus are fibrous, and Beijing people refer to as asparagus. White asparagus contains more trace elements, has more delicious taste and rich nutrition compared with green asparagus, and is in the reputation of 'the king of vegetables' and 'one of the ten famous vegetables in the world'.

China is the first country of production and export of the large reed shoots in the world. In 2011, the global asparagus harvesting area reaches 146 million hectares, and the domestic asparagus harvesting area reaches 132 million hectares, which accounts for 90 percent of the global total area. White asparagus instrument of gathering is mostly slender asparagus sword, and the time of gathering of white asparagus is mostly before the morning sun comes out or the evening sun is after the mountain, and the time of gathering is concentrated relatively, and the process of gathering takes time much, work load is big, therefore the harvest efficiency of present white asparagus is very low.

Through the literature search of the prior art, the Chinese patent application No. 201610887545.8 of 'a clamping and cutting type white asparagus harvesting device and method' adopts a clamping and cutting mode to harvest white asparagus, and the harvesting mode has the following aspects to be improved: the clamping and cutting actions have multiple steps, and the mechanical structure is complex in design; secondly, the cutting blade needs to be protected by an additional cutting board, so that the soil penetration resistance is large; thirdly, the white asparagus is mechanically damaged by the clamping plates in the picking process.

Aiming at the situation that the existing white asparagus harvesting tool is backward, the pull-cut white asparagus harvesting end effector is invented, the power is utilized to drive the whole harvesting end effector to move so as to realize the pull-cutting and the pulling of the white asparagus, and the throwing of the white asparagus is realized through the stretching of the cutter net, so that the operation steps are simpler, and the harvesting efficiency is improved.

Disclosure of Invention

The utility model discloses gathering the not enough of existence to white asparagus, providing a stretch-cut formula white asparagus end effector that gathers, realize cutting the root fast to white asparagus root, pulling out and throwing put, make the operation step more simple, improve the efficiency of gathering.

The utility model discloses end effector that draws white asparagus of cut formula to gather adopts following technical scheme: the upper and lower fixing plates, the supporting plate, the left and right stick knives and the cutting mechanism are arranged; the upper fixing plate and the lower fixing plate are composed of two steel plates, the steel plates are provided with notches and screw holes of the sections of the stick knives and used for fixing the two stick knives, and the upper fixing plate is L-shaped and is convenient to be connected with power; the supporting plate consists of four concave plates which are symmetrical left and right and are provided with screw holes for fixing; the left and right stick knives are composed of two long sticks with single-side cutting edges, and the bottom of the stick knife is provided with a sharp edge to reduce the resistance to soil penetration;

the stretch-cutting mechanism comprises: a cutter net, a pull cutter and a connecting piece; the cutter net is a spring steel sheet with a plurality of holes, the upper half part of the cutter net is approximately frame-shaped due to the separated holes of the upper half part of the cutter net, bamboo shoots are conveniently supported and fall off of soil, the size of the separated holes of the lower half part ensures that white asparagus can not pass through, on one hand, the bamboo shoots can be prevented from falling off when being pulled out, on the other hand, the soil can fall off, and the carrying of the soil is reduced in the root cutting and pulling process; the broaching and cutting tool is a tool with a blade at one side, the blade is convenient for cutting bamboo shoots, and a hole is formed at one side for fixing with a tool net; the connecting piece is a part for connecting the pull cutting knife and the stick knife.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model adopts the cutting-pulling type harvesting method, the harvesting end effector is driven by power to move and cut the root of the white asparagus after entering the soil, the hollowed-out cutter net and the harvesting end effector are integrally pulled up to realize the accurate pulling of the white asparagus, and compared with the manual harvesting of the white asparagus, a plurality of complicated harvesting steps are saved;

2. the harvesting end effector adopted by the utility model has smaller cross section area, smaller soil entering resistance, no closed space, less soil taking during the soil outlet, and the step of digging and backfilling soil is saved;

3. the utility model discloses convenient to use, low cost, easy maintenance.
