Description

Technical Field

[0001] This invention relates to the field of forestry planting equipment technology, specifically to a soil loosening device for forestry planting. Background Technology

[0002] In forestry planting, soil loosening is a crucial pretreatment step. Its purpose is to break up compacted soil structure, increase soil aeration and permeability, improve soil physical and chemical properties, and provide a favorable environment for seedling root growth. Existing forestry soil loosening equipment is mainly divided into two categories: large-scale towed soil loosening machinery and small handheld soil loosening tools. Large-scale towed soil loosening machinery typically uses a single-structure plow or rotary tiller for loosening, making it difficult to adapt to different forest types (such as young forests, mature forests, and economic forests) and different soil conditions (such as sandy loam, clay loam, and gravelly soils). Furthermore, it lacks flexibility in adjusting loosening depth and intensity, easily leading to incomplete loosening of deep soil or excessive disturbance of the surface soil, resulting in soil erosion. While small handheld soil loosening tools offer greater flexibility, their low operating efficiency and high labor intensity fail to meet the soil loosening needs of large-scale forestry planting.

[0003] In summary, traditional forestry soil loosening relies heavily on manual labor or single-function mechanical equipment, resulting in low efficiency, significant damage to soil structure, and an inability to adapt to different forest types and soil conditions. Particularly in forest areas with complex terrain and uneven seedling distribution, traditional equipment struggles to achieve precise and flexible soil loosening operations, negatively impacting seedling growth.

[0004] Therefore, there is an urgent need for an automated soil loosening device that can intelligently sense the environment and automatically adjust operating parameters. Summary of the Invention

[0024] In this invention, the surface of the track 12 is provided with anti-slip ridges and elastic buffer pads. The anti-slip ridges are distributed in an alternating pattern, and the elastic buffer pads are made of polyurethane material. Each of the two tracks 12 is provided with a first drive motor 11, and the front end of the chassis 14 is also connected to a traction frame 13.

[0025] In this invention, the lifting support 2 adopts a multi-stage hydraulic lifting structure to achieve a height adjustment of 0.5-2m.

[0026] In this invention, a plurality of pre-reserved grooves are uniformly arranged on the surface of the shallow soil loosening roller 78. Elastic soil loosening teeth 782 are slidably connected inside the pre-reserved grooves. A return spring 781 is provided between the elastic soil loosening teeth 782 and the pre-reserved grooves.

When the soil hardness is ≤5kg / cm², the elastic soil loosening teeth 782 are fully extended, and the soil loosening depth is 10-30cm. When the soil hardness is >5kg / cm², the elastic soil loosening teeth 782 cooperate with the return spring 781 to adaptively compress according to the hardness.

[0027] In this invention, both the shallow soil loosening unit and the deep soil loosening unit are connected to the column 71 at the tail end of the load-bearing platform 4 via a mounting frame.

A conical spiral drill 792 is provided on the surface of the rotating shaft 791, and multiple soil breaking blades 793 are evenly arranged axially on the surface of the rotating shaft 791. A connecting plate is provided at the end of the soil breaking blade 793 near the rotating shaft 791. The soil breaking blade 793 and the rotating shaft 791 are fixedly connected by fixing bolts through the positioning holes on the surface of the connecting plate and the fixing holes on the surface of the rotating shaft 791. The soil breaking blade 793 has an overall arc-shaped structure, and the blade side faces the rotation direction of the rotating shaft 791.

[0028] The present invention also includes a solar power supply component 6, which includes a solar panel 62, an energy storage battery 61, and a charging management module installed above the load-bearing platform 4. The solar panel 62 converts solar energy into electrical energy and stores it in the energy storage battery 61.

[0029] In this invention, the central control system incorporates a data processing module, an adaptive decision-making module, and an execution control module. The data processing module analyzes and processes data collected by the soil parameter detection component and the forest type identification component. The adaptive decision-making module determines the optimal soil loosening parameters based on the processed data and a pre-set forest type-soil-loosening parameter matching database. The execution control module controls the collaborative operation of each component based on the decision results of the adaptive decision-making module. The central control system also includes a built-in wireless communication module for data interaction with a remote monitoring center and is equipped with a touchscreen user interface.

[0030] The present invention also includes an anti-slip mechanism, which includes an arc-shaped retaining plate, soil fixing nails and a telescopic rod. The arc-shaped retaining plate is symmetrically arranged on both sides of the mounting frame. One end of the telescopic rod is connected to the mounting frame and the other end is connected to the arc-shaped retaining plate. The soil fixing nails are evenly distributed at the bottom of the arc-shaped retaining plate.

[0031] In this invention, the top of the soil moisture sensor 52, the soil hardness sensor 53, and the soil stone content detector 54 are all equipped with a detection cylinder 51. The detection cylinder 51 is fixedly connected to the surface of the load-bearing platform 4, and the driving end of the detection cylinder 51 is connected to the soil moisture sensor 52, the soil hardness sensor 53, and the soil stone content detector 54 respectively, for inserting the soil moisture sensor 52, the soil hardness sensor 53, and the soil stone content detector 54 into the soil to collect data on soil moisture, hardness, and stone content. The forest type identification component includes a high-definition camera 55 installed at the front end of the load-bearing platform 4 and an image recognition module integrated inside the high-definition camera 55, for identifying forest type and seedling distribution density.

[0032] Example: This example simulates the use of the soil loosening device in a spring soil loosening operation in a pine seedling forest with slightly compacted soil. The goal is to break up the compacted layer, enhance soil aeration and moisture retention, while avoiding damage to the unevenly distributed seedling root system.

[0033] The operator starts the device via the touchscreen interface of the central control system. Driven by the walking support mechanism 1, the device enters the work area. First, the forest type recognition component starts working. The high-definition camera 55 at the front of the load-bearing platform 4 captures images of the forest in front. The integrated image recognition module identifies the low-lying "seedling forest" type and performs a preliminary analysis of the distribution density of the seedlings.

[0034] Subsequently, the soil parameter detection component of the adaptive adjustment mechanism 5 is activated. The detection cylinder 51 actuates, inserting the soil moisture sensor 52, soil hardness sensor 53, and soil stone content detector 54 into the soil. Data acquisition results show that the soil moisture is 15%, the hardness is 4.8 kg / cm², slightly lower than the preset threshold of 5 kg / cm², and the stone content is low.

[0035] The data processing module within the central control system analyzes the collected data. The adaptive decision-making module then calls upon the built-in "forest type-soil-loosening parameter matching database" and, based on key information such as "seedling forest" and "soil hardness ≤ 5 kg / cm²", determines the optimal loosening scheme: deep loosening focuses on breaking up compaction, while shallow loosening employs full-depth loosening to avoid damaging seedlings, and the movement speed is kept low and steady.

[0036] Based on the decision results, the execution control module issues the following commands: It instructs the first drive motor 11 of the traveling support mechanism 1 to operate in low-speed mode, causing the entire traveling support mechanism 1 to move to the identified work area. It instructs the lifting support 2 to adjust the load-bearing platform 4 to a suitable height. It instructs the layered soil loosening mechanism 7 to prepare for fixed-point collaborative operation.

[0037] The layered soil loosening mechanism 7 is activated; its structure is as follows: Figure 4 As shown.

[0038] Deep soil loosening stage: The deep soil loosening unit at the front end works first. The third drive motor 79 starts, driving the rotating shaft 791 and the conical auger 792 at its end to rotate. The auger 792 drills into the soil, while the soil-breaking blade 793 on the surface of the rotating shaft 791 can effectively break up the compacted layer with a depth of about 25-35cm, improving the permeability of the deep soil.

[0039] Shallow loosening stage: Following this, the shallow loosening unit begins operation. Since the soil hardness is ≤5kg / cm², the elastic loosening teeth 782 on the surface of the shallow loosening roller 78 are fully extended under the action of the return spring 781.

[0040] The second drive motor 783 drives the shallow soil loosening roller 78 to rotate. The fully extended elastic loosening teeth 782 gently loosen the top 10-30cm of soil, effectively preserving the fine roots of the seedlings while leveling the ground surface. The hydraulic telescopic rod 76 finely adjusts the working angle of the shallow soil loosening roller 78 through the angle adjustment frame 77, ensuring flexible movement among the seedlings.

[0041] During the soil loosening stage, the anti-slip mechanism, under the action of the telescopic rod, adjusts the opening angle of the curved retaining plate according to the slope of the working area. The steeper the slope, the smaller the opening angle of the curved retaining plate, and vice versa. The opening angle of the curved retaining plate is 30°-120°. As the layered soil loosening mechanism 7 moves downward, the curved retaining plate moves downward accordingly, and the soil fixing nails at the bottom of the curved retaining plate insert into the working area to fix the surface soil and prevent soil slippage.

[0042] Throughout the operation, the solar power supply component 6 continuously provides power to the entire device. The solar panels 62 above the load-bearing platform 4 convert solar energy into electrical energy and store it in the energy storage battery 61, demonstrating the energy-saving and environmentally friendly characteristics of the equipment. At the same time, the central control system transmits the operation progress, equipment status, and soil data to the remote monitoring center in real time via the wireless communication module, allowing managers to remotely monitor the operation.

[0043] In this embodiment, the soil loosening device successfully achieved intelligent and precise soil loosening operations in seedling forests. Through the synergistic effect of environmental perception, intelligent decision-making, and layered soil loosening, it effectively improved the soil structure while maximizing the protection of seedling roots, achieving the expected goal of promoting growth and increasing yield, fully demonstrating the superiority and practicality of the invention.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.
