A double-helix vertical ditching fertilizer applicator

technical field

The invention relates to a ditching and fertilizing machine, in particular to a double-helix vertical ditching and fertilizing machine suitable for tea and orchards, and belongs to the technical field of agricultural and forestry machinery.

Background technique

As far as the applicant knows, the existing tea and orchard ditching and fertilizing machines mainly include chain type ditching and fertilizing machines, disc knife type ditching and fertilizing machines, and shovel type ditching and fertilizing machines. , complex structure, inconvenient use, and the process of digging out the soil and then filling the ditch is unavoidable when ditching, resulting in a lot of water loss.

Contents of the invention

The purpose of the present invention is to: aim at the problems existing in the above-mentioned prior art, propose a kind of double-helix vertical ditching fertilizer applicator that not only has a simple and compact structure, is convenient for transportation and maintenance, but also can reduce water loss as much as possible when ditching and fertilizing. .

In order to achieve the above objectives, the basic technical solution of the double-helix vertical ditching fertilizer applicator of the present invention includes a funnel-shaped fertilizer box (3-1) fixedly connected to the frame (1), and the bottom outlet of the fertilizer box is installed There is a spiral ditching fertilizer applicator (5) driven by a transmission mechanism. The spiral ditching fertilization applicator (5) has a hollow vertical ditching fertilization shaft (5-1), and the vertical ditching fertilization shaft (5- 1) There is a large spiral blade (5-2) on it, and a vertical ditching shaft (4-1) parallel to it is installed on the front side of the vertical ditching fertilization shaft (5-1). The groove shaft (4-1) has a small helical blade (4-2) whose direction of rotation is opposite to that of the large helical blade (5-2).

After the double-helix vertical ditching and fertilizing machine of the present invention is connected to the power tractor and driven by the power device, the front screw opener first opens a narrower ditch along the travel route of the tractor, and then the rear screw opener The furrow applicator expands into a wider furrow and at the same time, due to its vertical axis forms a fertilization channel, fertilizer is also applied into the furrow, thus completing the required rotary tillage fertilization operation in one pass.

A further perfection of the present invention is that at least one edge of the small helical blade (4-2) and the large helical blade (5-2) has groove cutter teeth.

The invention not only realizes the rotary tillage operation that can only be completed by the original bulky machinery with the dual helix mechanism of reciprocal direction and direction combined with reasonable configuration and mutual combination, but also organically combines the rotary tillage mechanism with the fertilization mechanism by means of the center feeding of the spiral shaft, which obviously simplifies the operation. The structure is improved, and the ditching cutter teeth added to the edge of the spiral blade greatly improve the ability to break the soil; especially, on the basis of a narrow ditch opened by the front spiral ditch, it is expanded into a wider ditch, and fertilizer is applied to the In the ditch, the effect of covering the soil after fertilization is excellent, and the fertilizer is directly delivered to the inside of the soil almost without moving the soil, which has achieved an unexpected effect that the soil almost does not need to be dug out and refilled, so there is very little water loss.

Further, the frame is provided with upper and lower attachment interfaces (1-1, 1-2) which are attached to the tractor, and the upper attachment interface (1-1) is connected to the fertilizer box (3-1) through one end. Bottom fixed adjustable length post connection.
