A step-on shovel for rapid fertilization of red soil dry land

Abstract

The present invention discloses a step-type red soil dry land rapid fertilization shovel, comprising a shovel handle, a shovel rod, a shovel head and a fertilizer box. Fertilizer is loaded into the fertilizer box, and the dry land soil is pried open to a certain depth and width by stepping on the shovel head. The shovel handle is held tightly with both hands and squeezed downward to drive the pull rod to move upward. The pull rod opens the inner cover of the fertilizer box discharge port, and the stirring rod is stretched to bring out the fertilizer, thereby completing the fertilization process. The whole process produces two stirring effects, so that the fertilizer in the fertilizer box will not be compacted. The present invention is easy to operate, saves labor and energy, and at the same time avoids the problem of fertilizer loss caused by manual shallow fertilization, thereby improving the fertilizer utilization rate and the work efficiency of loosening the soil and fertilizing.

Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a step-on type red soil dry land rapid fertilization shovel. Background Art

[0002] Red soil dryland is an important agricultural soil resource in southern my country. The rational use of red soil dryland resources occupies an important strategic position in the sustainable development of agriculture in southern my country. For a long time, due to the fact that red soil dryland soil is generally sticky, easy to compact, and relatively poor, the power consumption of mechanical operation is large, and it is not easy to achieve large-scale mechanized operation, especially weak links such as fertilization and plant protection. Fertilization is an important part of agricultural and forestry production, and an important means to promote the normal growth of crops and ensure rapid growth and high yield. Traditional fertilization methods include fertilizer broadcasting, furrow application, hole application, etc. Modern fertilization technologies include soil testing formula fertilization, flushing fertilizer, variable control fertilization, etc. Rhizosphere fertilization is to apply fertilizer around the root system so that the root system can easily absorb nutrients, so that the seedlings grow rapidly and the fruits grow fuller. The promotion and use of a step-down red soil dryland rapid fertilization shovel can effectively save labor, quickly and labor-saving fertilization, and improve fertilizer utilization. The basic principle is to use a shovel to quickly apply fertilizer to the root zone of dryland crops. Summary of the invention

[0003] The present invention provides a step-on type red soil dry land rapid fertilization shovel to solve the technical problems of difficulty in fertilizing red soil dry land, difficulty in mechanized operation, and time-consuming and labor-intensive manual fertilization.

[0024] The invention provides a shovel for rapid fertilization in dry red soil. The shovel head is stepped on to open trenches. The shovel head can be stepped on and trenches can be opened appropriately according to the demand of the roots of vegetation for fertilizer. The operation is simple, the ability of fertilizer to enter the soil is increased, soil disturbance is reduced, and the agronomic requirements for root fertilization of dryland crops are met.

[0025] The invention provides a step-down type red soil dry land rapid fertilization shovel, the injection port is a screw cover, and can be connected to an external backpack fertilizer box through a connecting hose to achieve a continuous working state. For some dryland crops that require less fertilizer, fertilization can also be directly carried out by fixing the amount of fertilizer. By adjusting the position of the movable pull ring, the angle of the discharge port switch can be effectively controlled to achieve the effect of controlling the amount of fertilizer, and quantitative fertilization can be effectively applied according to the growth of the crop.

DETAILED DESCRIPTION

[0030] The basic working principle of a step-type red soil dry land rapid fertilization shovel is to achieve a certain trenching width and depth by stepping on the shovel head, and by pressing the shovel handle downward, the return spring on the shovel rod is squeezed, and the shovel rod moves upward relatively by the spring force until the upper part of the shovel rod 2 presses against the shovel handle 1; the relative displacement of the shovel handle 1 and the pull ring on the shovel rod 2 during the force process causes the movable ring connected to the shovel rod 2 to move upward. The pull rod 18 on the movable ring is pulled up to open the cover of the fertilizer box 4 discharge port 5; thereby driving the stirring rod 20 on the cover to produce a stretching effect. After the extrusion is completed, the lower return spring 19 is squeezed and returned to its original position. The return action causes the movable ring 10 to rebound to its original position, the pull rod 18 returns to its original position, and the cover of the fertilizer box 4 discharge port is covered again. At the same time, the stirring rod 20 returns to its original position under the action of the lower return spring 19, completing the entire foot-type fertilization process. This process can manually control the degree of stepping according to the growth of crops, and realize precise fertilization lightly, quickly and effectively. The design of the stirring rod 20 on the lid of the upper and lower feeding port of the fertilizer box 4 produces a stirring effect through the closing process of the lid, so that the fertilizer will not be hardened in the fertilizer box 4. The whole fertilization process is fast and convenient, and has strong practicality.
