Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fertilizing equipment, in particular, relates to a drilling fertilizing equipment for rubber tree planting and a fertilizing method. BACKGROUND

[0002] Rubber tree is a common tree in tropical regions, and is an economic crop that can extract natural rubber. Rubber forest inter-row refers to the gap between two rows of rubber trees in a rubber tree plantation. The rubber forest inter-row facilitates the work of the management personnel, such as inspection, pruning, and fertilization, and has the effects of promoting the growth of rubber trees, facilitating management, benefiting soil conservation, and water conservation. At present, the common practice of rubber plantation fertilization is to dig a fertilizing ditch on one side of a single row of rubber trees and to spread organic materials and chemical fertilizers in the fertilizing ditch. In order to improve the economic benefits of rubber trees, the management personnel will regularly fertilize in the inter-row to improve the yield of natural rubber. Rubber trees are mostly planted in tropical regions with high rainfall. When fertilizing the ground in the rubber forest inter-row, the fertilizer spread on the ground surface will be washed away by rain, resulting in fertilizer loss and low nutrient utilization rate. In addition, the root system of rubber trees can grow into the underground space of the inter-row, and the absorption roots are mainly concentrated in the soil layer with a depth of 10-20 cm. In order to improve the nutrient utilization efficiency of the rubber forest, the management personnel will consider the method of deep fertilization of the ground in the rubber forest inter-row. Due to the dense root system in the soil layer with a depth of 10-20 cm in the rubber forest inter-row, the traditional surface soil tillage fertilization method and mechanical operation will cause a lot of damage to the root network, seriously affecting the health of rubber trees and the normal production of natural rubber latex. Therefore, it is urgent to develop a device and a fertilizing method suitable for deep fertilization of the ground in the rubber forest inter-row.

[0003] Compared with the traditional fertilization method, the drilling fertilization method not only avoids damage to the root system during deep fertilization of the ground in the rubber forest inter-row, but also enables the rubber trees to absorb nutrients more efficiently. During the drilling fertilization process, periodic deep fertilization is required. The traditional manual drilling fertilization not only has low efficiency, but also causes uneven depth in different undulating terrains, resulting in poor fertilization effect. The existing continuous row drilling machine lacks a precise depth adjusting mechanism and is difficult to adapt to changes in hilly terrain. The existing drilling fertilization method usually involves manually introducing fertilizer into the drilling hole after drilling, which is low in working efficiency. SUMMARY

[0017] Preferably, the height of the adjusting linkage groove is the same as the height of the horizontal connecting rod.

[0018] A method for fertilizing rubber tree planting, using the aforementioned drilling fertilization equipment, includes the following steps;

[0019] Before drilling, the lifting sleeve moves close to the rubber tree. The lifting sleeve of each drilling unit moves to the position corresponding to the rubber tree. The lifting sleeve drives the lifting drill rod to move vertically. After the lifting sleeve contacts the ground, it stops moving. The feed pipe is rotated to drive the lifting drill rod to rotate. The feed pipe is rotated to drive the lifting drill rod to move vertically downward out of the lifting sleeve. The lifting drill rod drives the spiral blade to rotate to drill a hole in the ground.

[0020] After drilling to a certain depth, fertilizer enters the lifting drill rod through the fertilizer feed pipe and rotating feed pipe. The pressure block moves upward, and the elastic baffle releases its stored force and moves upward to reset until it engages with the bonding groove, thus restricting the rotation of the lifting drill rod. At the same time, the discharge port opens. When the elastic baffle moves vertically upward to open the discharge port, the fertilizer can be discharged from the discharge port. When the discharge port is open for discharge, the lifting drill rod moves vertically upward, and the fertilizer flows into the drill hole, completing the fertilization.

[0021] Compared with the prior art, the present invention provides a drilling and fertilization device and method for rubber tree planting, which has the following beneficial effects:

[0022] 1. The movable mounting plate moves closer to the rubber tree. The adjusting moving block of each drilling unit moves, causing the lifting sleeve to move to the position corresponding to the rubber tree. The lifting sleeve drives the lifting drill rod to move vertically. After the lifting sleeve contacts the ground, it stops moving. The feed pipe is rotated, causing the lifting drill rod to rotate. The feed pipe is rotated, causing the lifting drill rod to move vertically downward out of the lifting sleeve. The lifting drill rod drives the spiral blade to rotate, drilling holes in the ground. The position of the lifting drill rod in each drilling unit can be moved independently, and the spacing between the lifting drill rods can match the standard row spacing of the rubber trees, improving the applicability of the equipment. The lifting drill rod only starts drilling after the lifting sleeve contacts the ground, so that the lifting drill rod can make the drilling depth the same when facing different terrains, preventing different drilling depths and improving fertilization accuracy.

[0023] 2. When the lifting drill rod stops rotating, the pump delivers fertilizer from the feed hopper through the feed connecting pipe, fertilizer pipe, and fertilizer feed pipe to the rotating feed pipe. When the fertilizer in the rotating feed pipe enters the lifting drill rod, the elastic baffle moves vertically upward to open the discharge port, allowing the fertilizer to be discharged from the discharge port. When the discharge port is open for discharge, the lifting drill rod moves vertically upward, and the fertilizer flows into the borehole, completing the fertilization. The lifting drill rod has a hollow design to store fertilizer. After drilling is completed, the lifting drill rod opens the discharge port for fertilization, allowing the fertilizer to be discharged into the borehole during the lifting drill rod's movement, eliminating the need to subsequently introduce fertilizer into the borehole and improving fertilization efficiency.

[0024] 3. When the movable mounting plate moves towards the adjusting cylinder, the horizontal connecting rod moves into the adjusting linkage groove. The adjusting linkage groove presses against the horizontal connecting rod, causing it to move. The horizontal connecting rod then moves the depth limiting block out of the limiting groove. The adjusting cylinder drives the depth adjusting plate to move vertically, thereby causing the depth limiting plate to move vertically. When the adjusting linkage groove no longer presses against the horizontal connecting rod, the depth limiting block moves into the limiting groove, and the depth limiting plate is fixed in position. By adjusting the position of the depth limiting plate on the limiting connecting rod, the maximum drilling depth of the lifting drill rod is fixed, thereby controlling the depth of each drilling operation.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
