Abstract

The invention discloses a double-disc type rooting device which comprises two opposite rooting discs, wherein the two opposite rooting discs are supported on a rotating shaft support through a rotating shaft, the inner surface and the outer surface of each rooting disc are provided with spatial curved surfaces, inclined included angles are formed between the rotating shaft of each rooting disc and a horizontal plane and between the rotating shaft of each rooting disc and the advancing direction of each rooting disc, and the two rooting discs are in contact or have a gap below the rear part of the rotating shaft. The invention rotates by utilizing the acting force of the soil on the rooting disc when the soil advances, does not need to be additionally provided with a driving device, and has simple structure and small working resistance. Therefore, each set of the root lifting device can be respectively arranged on each row of the harvesting mechanism, and each row of the root lifting device independently completes root cutting of each row through terrain following, so that the vegetable furrow cutting device is more suitable for height change of vegetable beds.

Description

Double-disc type rooting device

Technical Field

The invention relates to a vegetable harvesting device, in particular to a double-disc type rooting device for orderly rooting harvesting of stem and leaf vegetables.

Background

The ordered harvesting of the stem and leaf vegetables is to cut the vegetables planted on the soil by a cutting device and then convey and collect the vegetables in order, so that the cutting device is an important part of the ordered harvesting. The existing cutting device mainly comprises a band saw type cutting knife and a reciprocating type cutting knife, wherein the cutting knife is used for cutting off stems from soil by crossing the ridge width during working so as to facilitate subsequent clamping and conveying. However, in China, the varieties of the stem and leaf vegetables are many, the stem and leaf of part of vegetables are very close to the root system, the stem and leaf can be cut and scattered by a slightly high cutting height, the sequential conveying and collection are not facilitated, and the rotting is easy to accelerate. And because the growth period of the vegetables is longer, under the action of factors such as plant protection, ridging, weeding and vegetable growth randomness, the heights of the roots of the vegetables are different, so that the suitable cutting height is limited to a smaller range, and the variety of the vegetables suitable for the cutting mode is limited. Therefore, thereby from root cutting with the area root results of stem leaf class dish from soil play out can avoid the difficult problem that the cutting height is difficult for confirming, can also improve the storage time of post harvest vegetables, nevertheless current cutting knife will accomplish area root results and need carry out the cutting operation under the soil at whole rectangular pieces of land in a field width, will cause the cutting knife wearing and tearing aggravation, consequently not suitable harder or the higher soil of grit content.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a double-disc type rooting device which can independently cut vegetable roots and take out vegetables from soil in each row.

The utility model provides a double-disk rooting device, double-disk rooting device is including two relative rooting disk of slope, and two rooting disks support on the pivot support through the pivot, the interior external surface of rooting disk have the space curved surface, and the rotation axis of rooting disk all has the slope contained angle with horizontal plane and advancing direction, two rooting disks contact below or gapped behind the revolving axle.

When the double-disc type rooting device works, the double-disc type rooting device is fixed on a harvester, the rotating shaft support moves forward under the pushing of the harvester, the rooting disc rotates by means of friction of soil on the disc surface, soil blocks for planting vegetables in the middle and soil blocks on the outer side are cut by the disc edge of the rooting disc in the advancing process, and meanwhile, longer main roots of the vegetables and root systems on the side surfaces are cut off; because there is certain contained angle between two plays root dish for middle part soil is crushed by the extrusion at the in-process that advances, makes the hookup of root system and soil not hard up, because two quotations are nearest the position and are located the below behind the revolving axle, consequently the inclination that the below position formed behind two quotations still has the lifting effect to soil, orders about the vegetables of cutting off the root system and uses the removal, cooperates the centre gripping conveyor centre gripping vegetables of harvester this moment and accomplishes the action of upwards promoting and make vegetables break away from soil completely, thereby accomplishes the operation of playing root.

The inner surface and the outer surface of the rooting disc are conical surfaces or spherical surfaces.

The rooting disc is of a hollow structure.

By adopting the rooting disc with the hollow structure, part of cracked soil can flow out from the hollow part of the disc surface in the use process, so that the connection between the root system and the soil is further reduced, and the congestion of the soil caused by the reduction of the flow channel surface is also reduced.

The clearance between the two rooting disks at the rear lower part of the rotating shaft is 0-3 mm.

In summary, compared with the prior art, the invention has the following advantages:

(1) the double-disc type rooting device cuts off the root system under soil and extrudes cracked soil to reduce the connection between the root system and the soil, thereby completing the rooting operation without damaging stems and leaves, and therefore, the height of the position of the stem and the leaf from the root does not need to be considered, so that the double-disc type rooting device is applicable to most stem and leaf vegetables, and in addition, partial root system is kept to be favorable for prolonging the storage life.

(2) The double-disc type rooting device rotates by utilizing the acting force of soil on the rooting disc when the double-disc type rooting device moves forward, does not need to be additionally provided with a driving device, and has simple structure and small working resistance. Therefore, each set of the root lifting device can be respectively arranged on each row of the harvesting mechanism, and each row of the root lifting device independently completes root cutting of each row through terrain following, so that the vegetable furrow cutting device is more suitable for height change of vegetable beds.

(3) The rear section of the double-disc type rooting device is lifted and clamped to be conveyed and matched for operation, so that the vegetables can be kept in an upright state to complete rooting operation, and the ordering of harvesting of stem-leaf vegetables is improved.

(4) The rooting disk only partially works in the soil, the rotation of the rooting disk is driven by the soil, and the relative speed of the rooting disk and the soil is low, so the abrasion is small.
