Abstract

The invention discloses a double-disc rooting device. The double-disc rooting device comprises two obliquely opposite rooting discs. The two rooting discs are supported on a rotating shaft support through a rotating shaft. The inner and outer surfaces of the disc have a space curved surface, and the rotation axis of the rooting disc has an inclined angle with the horizontal plane and the advancing direction, and the two rooting discs are in contact or have a gap behind the rotating shaft. The invention utilizes the action force of the soil on the root plate to rotate when advancing, and does not need a separate driving device, and has a simple structure and low working resistance. Therefore, each set of rooting devices can be separately installed on each row of harvesting mechanisms, and each row can independently complete the root cutting of each row through terrain follow-up, which is more suitable for the height change of vegetable borders.

Description

Double disc rooting device

technical field

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

Background technique

The orderly harvest of stem and leaf vegetables is to cut the vegetables planted on the soil by the cutting device and then transport and collect them in an orderly manner. Therefore, the cutting device is an important part of the orderly harvest. Existing cutting devices mainly include band-saw cutters and reciprocating cutters. When working, the cutters span across the border to cut off the stems and separate them from the soil for subsequent clamping and conveying. However, there are many varieties of stem and leaf vegetables in my country, and the stems and leaves of some vegetables are very close to the root system. If the cutting height is slightly higher, the stems and leaves will be cut apart, which is not conducive to orderly transportation and collection, and it is easy to cause accelerated decay. In addition, due to the long growth period of vegetables, under the action of plant protection, soil cultivation, weeding and the randomness of vegetable growth, there are differences in the root height of vegetables, so the suitable cutting height is limited to a small range, resulting in limited vegetable varieties suitable for this cutting method. . Therefore, the rooted harvesting by cutting from the root to lift the stem and leafy vegetables from the soil can avoid the difficult problem of determining the cutting height, and can also improve the storage time of the vegetables after harvesting, but the existing cutter needs to complete the rooted harvesting It is necessary to carry out sub-soil cutting operations over the entire border width, which will increase the wear of the cutter, so it is not suitable for soils with hard or high sand and gravel content.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a double-disc rooting device that can individually cut vegetable roots and lift vegetables from the soil in each row.

A double-disc rooting device, the double-disc rooting device comprises two obliquely opposite rooting discs, the two rooting discs are supported on a rotating shaft bracket through a rotating shaft, and the inner and outer surfaces of the rooting discs have a space curved surface , and the rotating shaft of the rooting disc has an inclined angle with the horizontal plane and the advancing direction, and the two rooting discs are in contact or have a gap behind the rotating shaft.

When the double-disc rooting device is working, the double-disc rooting device is fixed on the harvester, and the rotating shaft bracket moves forward under the push of the harvester. The rooting plate rotates by the friction of the soil on the surface of the plate. The edge of the root plate cuts the soil block and the outer soil block for planting vegetables in the middle, and at the same time cuts off the longer main root of the vegetable and the root system on the side; because there is a certain angle between the two rooting plates, the soil in the middle is advancing. In the process, it is squeezed and broken, which loosens the connection between the root system and the soil. Since the closest part of the two disk surfaces is located behind and below the rotating shaft, the inclination formed by the rear and lower parts of the two disk surfaces also has a lifting effect on the soil, which drives the vegetables that cut off the root system. Using the upper movement, at this time, the clamping and conveying device of the harvester is used to clamp the vegetables and complete the upward lifting action to completely separate the vegetables from the soil, thereby completing the rooting operation.

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

The rooting disc has a hollow structure.

Using the rooting plate with the hollow structure, part of the fragmented soil can flow out from the hollow part of the plate during use, thereby further reducing the connection between the root system and the soil, and also reducing the soil congestion caused by the reduction of the flow channel surface.

The gap between the two rooting discs at the rear and bottom of the rotary shaft is 0-3 mm.

To sum up, the present invention has the following advantages compared with the prior art:

(1). The double disc rooting device cuts off the root system under the soil and squeezes the fragmented soil to reduce the connection between the root system and the soil, so as to complete the rooting operation without damage to the stems and leaves, so there is no need to consider the distance between the stems and leaves from the root. High and low, so it can be applied to most stem and leaf vegetables. In addition, retaining part of the root system is also beneficial to prolong the storage period.

(2). The double-disc rooting device utilizes the force of the soil on the rooting plate to rotate when it moves forward, and no additional driving device is required. The structure is simple and the working resistance is small. Therefore, each set of rooting devices can be separately installed on each row of harvesting mechanisms, and each row independently completes the root cutting of each row through terrain follow-up, which is more suitable for the height change of vegetable borders.

(3). The back-end lifting of the double-disc rooting device cooperates with the clamping and conveying operation, which is beneficial to the vegetables maintaining an upright state to complete the rooting operation, and improves the orderliness of the harvest of stem and leafy vegetables.

(4). Only part of the rooting plate works in the soil, and the rotation of the rooting plate is driven by the soil. The relative speed between the rooting plate and the soil is low, so the wear is small.
