Description

Walnut tree fertilizer injection unit

Technical Field

The invention relates to the technical field of fertilization, in particular to a walnut tree fertilization device.

Background

The walnut is a food which is frequently eaten in daily life, can be eaten raw or fried, can be used for pressing oil, preparing cakes, candies and the like, has delicious taste, has high nutritional value and medicinal value, and has great beneficial effects on human bodies. During the growth of walnut trees, various mineral nutrient elements are required to be absorbed from the soil to maintain the normal growth and development of the walnut trees, but most of the nutrients are still provided by fertilization. For perennial walnut trees, the branches and leaves tend to grow well, and the fertilizer requirement is high. The current fertilizing method for perennial walnut trees is completed by means of manual ditching and deep burying, but the method is troublesome, high in manual strength and inaccurate in fertilizing position, and in order to solve the problem, the prior art adopts a method of punching holes towards the ground by using hard objects such as steel drills and the like under the walnut trees and then throwing the fertilizers into the holes, but the operation has the defect that the roots of the walnut trees are damaged in the punching process due to sharp tips at the ends of the steel drills.

Disclosure of Invention

The invention aims to provide a fertilizer device which is suitable for fertilizing walnut trees with deeper root systems, has good fertilizer effect and is not easy to damage the root systems of the walnut trees.

In order to achieve the above purpose, the technical scheme of the invention is to provide a walnut tree fertilizing device, which comprises a hole rotating mechanism and a spreading mechanism, wherein the hole rotating mechanism comprises a cylinder, a pressure spring and a rotating head, the upper end of the cylinder is closed, the lower end of the cylinder is open, and the cylinder comprises a top surface and a side wall; the material spreading mechanism comprises a material conveying pipe, a telescopic pipe and a hopper; the lower end of the cylinder is fixedly connected with the rotary head through a pressure spring, the rotary head consists of rotary blocks, and the rotary blocks are arc-shaped; the rotary hole mechanism is internally provided with a cavity through a whole body, and a telescopic cylinder fixedly connected with the top surface is arranged in the cavity; the conveying pipe is connected with a telescopic cylinder, and the telescopic length of the telescopic cylinder is longer than the length from the bottom end of the conveying pipe to the tip end of the rotary head; the hopper is arranged on the side wall, and the hopper is communicated with the conveying pipe through the telescopic pipe. The beneficial effect of this scheme is: the fertilizer can be conveyed to the deep part of the root system of the walnut tree after being perforated by the fertilizer application device, the fertilizer application effect is good, and meanwhile, the problem that the root system is easily damaged by the transfer head in the perforation process is effectively avoided; when the punching mechanism gradually enters the soil, the turner can be in contact with the walnut tree roots, the turner is arc-shaped, meanwhile, the hardness of the tree roots is higher than that of surrounding soil, the turner can deviate in the process of continuously applying force to punch holes, and accordingly the pressure spring is driven to deviate, so that the turner can bypass the tree roots, and damage to the walnut tree roots is avoided.

Further, a baffle is welded at the joint of the compression spring and the lower end of the side wall, and the angle between the baffle and the compression spring is 5 degrees. The beneficial effect of this scheme is: can effectually avoid barely pressure spring offset angle too big through setting up the baffle to lead to turning round and lateral wall dislocation too serious, can't continue to punch.

Further, the upper end of the side wall is provided with a handle. The beneficial effect of this scheme is: an operator can hold the handle to apply pressure downwards to punch holes, and the operation is convenient.

Further, the arc angle of the rotating block is 20 degrees. The beneficial effect of this scheme is: the arc angle is 20 preferred angles of this scheme, and most points of arcwall face and root contact can all effectively bypass the root under this angle, avoid its damage.

Further, the upper wall and the side wall are integrally formed. The beneficial effect of this scheme is: the integrated into one piece is convenient to cast, and the structure is more stable simultaneously.

By adopting the technical scheme, the fertilizer can be firstly punched and then thrown into the deep part of the root system, so that a better fertilization effect is achieved, and meanwhile, the problem that the roots of the walnut trees are damaged in the punching process is effectively avoided.

Detailed Description

Example 1

The walnut tree fertilizing device shown in figures 1 and 2 comprises a hole rotating mechanism and a spreading mechanism from outside to inside, wherein the hole rotating mechanism comprises a cylinder with the upper end closed and the lower end opened, a pressure spring 3 and a rotating head 4 from top to bottom; the cylinder comprises a top surface 1 and a side wall 2, the top surface 1 and the side wall 2 are integrally formed, the upper end of the side wall 2 is provided with a handle 12, the lower end of the cylinder is welded with the rotary head 4 through a pressure spring 3, a baffle 11 is welded at the joint of the pressure spring 3 and the lower end of the cylinder, the angle between the baffle 11 and the pressure spring 3 is 5 degrees, and the offset angle of the pressure spring 3 is not too large; the rotary head 4 consists of rotary blocks 8, the rotary blocks 8 are arc-shaped, the arc angle is 20 degrees, most points of the arc surface under the angle can be contacted with the tree root to effectively bypass the tree root, and the damage of the tree root is avoided; a cavity 9 is arranged in the whole body inside the hole rotating mechanism, and a telescopic cylinder 10 fixedly connected with the top surface 1 is arranged in the cavity 9; the spreading mechanism comprises a conveying pipe 5, a telescopic pipe 6 and a hopper 7, wherein the conveying pipe 5 is connected with a telescopic cylinder 10, and the telescopic length of the telescopic cylinder 10 is longer than the length from the bottom end of the conveying pipe 5 to the tip end of the rotating head 4, so that the conveying pipe 5 can freely enter and exit from the tip end of the rotating head 4, and the fertilization function is realized; the hopper 7 is arranged at the upper end of the side wall 2, and the hopper 7 is communicated with the conveying pipe 5 through the telescopic pipe 6.

When fertilization is needed, the handle 12 is held to apply pressure downwards to rotate the hole mechanism, the pressure spring 3 is compressed to the maximum extent, and thus the rotary heads 4 are tightly folded together; when the turning head 4 contacts the root of the walnut tree, the turning head 4 is arc-shaped, and meanwhile the hardness of the root is higher than that of surrounding soil, in the process of continuously applying force, the turning head 4 can shift leftwards or rightwards, so that the pressing spring 3 is driven to shift leftwards or rightwards, the turning head 4 can bypass the root of the walnut tree, and the damage of the root of the walnut tree is avoided.
