Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an offset cutting device for a deep tillage and fertilization machine. Background Technology

[0002] As a perennial woody economic crop, the quality of pear tree root development directly affects nutrient absorption, stress resistance, and fruit yield. In recent years, a synergistic intervention method based on root regeneration response mechanisms has been developed, combining the stress effect of root damage with precise local nutrient delivery for the first time. Based on the callus differentiation pattern of pear tree roots (the critical period for absorbing root primordia formation is 24-72 hours after root pruning), a specially formulated slow-release fertilizer is applied to the root pruning wound, utilizing the apical trophotropic growth characteristics to guide the directional development of new roots. Compared to existing technologies, this approach increases the density of newly formed absorbing roots by more than 2.3 times and fertilizer utilization exceeds 65%, providing a novel solution for rejuvenating pear tree root function and achieving sustainable high yields.

[0003] Currently, deep loosening and fertilization in pear orchards rely entirely on manual root pruning, soil loosening, and fertilization. Root pruning and soil loosening are carried out separately from fertilization, requiring machines to work in the orchard multiple times. This not only results in high labor intensity, low production efficiency, and high operating costs for manual labor.

[0004] In addition, existing deep tillage and fertilization machines require a safe working distance of ≥1.5m. If they deviate from the target root system, they will be unable to cut the roots at the specified distance on the pear tree. When attempting to reduce the working radius, tree branches, protruding roots on the ground surface interfere with the rigid structure of the machine. This can cause the deep tillage shovel to deviate from its intended trajectory, or even cause the hydraulic system to overload and shut down, resulting in a high rate of work interruption. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, an offset cutting device for a deep tillage fertilizer applicator is provided.

Hooks are installed at both ends of the top surface of the connecting column, and the grooves of the hooks are set downwards.

[0016] Furthermore, the cutting assembly is covered with a housing, which is mounted on the conveyor mounting box of the conveyor assembly via a connecting bracket.

[0017] The beneficial effects of this utility model are: the central axis of the cutting blade assembly of this utility model is offset from the central axis of the connecting bracket, avoiding the tree trunk to achieve close-range operation, achieving the minimum operating radius, and improving the accuracy of the root cutting range;

[0018] Meanwhile, by integrating the root pruning-deep loosening-fertilizer mixing functional modules, the system can complete all three operations in a single field visit, reducing the operation time by 2 / 3 compared to traditional manual step-by-step operations, thus improving production efficiency and reducing labor costs per acre. Precise root pruning and synergistic fertilizer application are based on the callus differentiation window of pear tree roots. Fertilizer is applied simultaneously to the root pruning wound, utilizing the root tip's fertilization tendency to induce directional growth of new roots and improve fertilizer utilization.

The cutting disc component 4 performs the triple tasks of root cutting, deep tillage, and fertilizer mixing. The central axis of the cutting disc component 4 is offset from the central axis of the connecting bracket 1 to avoid the tree trunk and achieve close-range operation, thus achieving the minimum operating radius and improving the accuracy of the root cutting range.

[0041] In addition, the cutting plate assembly 4 is covered with a cover 5 to reduce soil splashing. The cover 5 is installed on the conveying mounting box 21 of the conveying assembly 2 via a connecting frame 6.
