Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery devices, and particularly relates to a dual-mode orchard gas explosion deep loosening machine. Background Art

[0002] Subsoiling, one of the core technologies of conservation tillage, is an agricultural technique for improving soil structure. It aims to improve soil aeration, water retention, and fertility, thereby increasing nutrient utilization and soil moisture retention, promoting crop root growth, and increasing yields. Subsoiling is used to eliminate soil compaction and restore soil productivity. Currently, there is a lack of machines for subsoiling the deep root layer of fruit trees during the growing season. Manual digging or the use of large subsoiling machines is commonly used. This method is inefficient, labor-intensive, and has high production costs. Furthermore, the soil turning process can easily damage the fruit tree roots. Therefore, the use of subsoiling machines for fruit trees has become an inevitable development trend in orchard soil management and improvement, and has become a research focus and hotspot.

[0003] Research has found that, especially in the past two decades, China's research focus has been on methods to reduce tillage resistance using subsoiling tools. Currently, the main subsoiling tools used in orchards both domestically and internationally are crawler-type self-propelled orchard subsoiling and fertilizing machines.

[0004] Currently, pneumatic subsoilers are widely used in practical soil tillage operations. Pneumatic subsoil technology uses compressed air or airflow to loosen the soil, effectively improving soil aeration and permeability, regulating the ratio of solids, gases, and liquids in the soil, activating soil microbial activity, and enhancing soil fertility and bioactivity, contributing to crop growth and the healthy development of ecosystems. Pneumatic subsoil also increases soil porosity and water retention, improving drought resistance and water retention. It also loosens the soil, breaking up the plow base and reducing tillage resistance.

[0005] At present, the existing models of orchard deep tillage and fertilization machines have realized the functions of deep tillage and quantitative fertilization, but they are generally models that are matched with tractors. In addition, they are limited by the working space in the orchard, making it inconvenient to walk over obstacles in the field and to turn. Moreover, they can only deep tillage on one side of the fruit trees. Since the deep tillage machines are too large, deep tillage cannot be carried out between the fruit trees, which affects the working efficiency and the deep tillage effect. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the current deep tillage technology in orchards and change the original deep tillage method of orchards. Therefore, the present invention designs a dual-mode gas explosion deep tillage equipment suitable for orchards. The carrying tool moves according to the row spacing between plants and has a turning function. The electric telescopic arm can adjust the length according to the distance between plants. When the air gun reaches the specified position, the telescopic arm moves down along the path of the guide rail and inserts the air gun into the soil to a certain depth to complete the gas explosion deep tillage operation; when encountering complex ground conditions, the mobile carrying platform cannot reach the vicinity of the plants. At this time, the operator removes the air gun from the clamping device of the electric telescopic arm, and the gas transmission device can be configured with a length according to demand, and the operator can hold it in hand for deep tillage operations, which neither turns over the soil layer nor damages the root system of the fruit tree. Gas explosion deep tillage operations can also be performed around the fruit tree, and the deep tillage device adopts a double-layer design. Before the gas explosion deep tiller penetrates the soil, the air inlet valve is closed and the angle adjustment device is used. The angle of the inner rod is adjusted so that the inner and outer air outlets in the self-closing soil penetration device are misaligned, thereby achieving the purpose of closing the air outlet and avoiding soil entering the air pipe and causing blockage during the penetration of the soil. After the operator penetrates the orchard gas explosion deep loosening machine into the soil through the foot-operated device, the inner and outer air outlets in the self-closing soil penetration device are overlapped again through the angle adjustment device to open the air outlet, and then the air inlet valve is opened. The high-pressure gas generated by the air generating device enters the soil through the inner tube of the gas explosion deep loosening machine, and performs pneumatic splitting on the plow bottom layer around the gas explosion center. This invention solves the limitation that large-scale orchard deep loosening machines cannot perform deep loosening around fruit trees. It has dual modes and solves the application in various complex field soil environments without turning over the soil layer and damaging the root system of the fruit trees. The inner and outer double-layer design of the deep loosening machine's soil entry device avoids soil entering the airway and causing blockage during the penetration of the gas explosion deep loosening machine into the soil.

Then the operator uses his foot to step down on the foot pedal to step the orchard gas explosion deep loosening machine into the deep loosening area that needs deep loosening, and uses the adjustment device to change the angle of the inner layer rod of the self-closing soil penetration device so that the inner and outer layer high-pressure gas jet outlets overlap and open. At this time, the valve of the gas transmission device is opened, and the high-pressure gas quickly enters the soil through the outlet of the soil penetration device, achieving the purpose of deep loosening the soil.

[0018] The self-closing soil penetration device, through the design of inner and outer double layers, adjusts the angle of the inner layer air outlet when penetrating the soil, so that the inner and outer layer air outlets are misaligned, thereby achieving the purpose of closing the air outlet, and preventing the soil from entering the interior of the gas explosive deep loosening machine through the air outlet when the gas explosive deep loosening machine penetrates the soil, causing the internal air pipe to be blocked, resulting in a short service life of the gas explosive deep loosening device.

[0023] In the above technical solution, the handheld operating device is a handheld rod, which is connected to the gas explosion deep loosening machine through a threaded nut and is used by the operator to hold it for deep loosening operations.

[0024] In the above technical solution, the pedal device is a pair of pedal rods, which are rigid structures and are welded to the orchard gas deep loosening machine at a certain height, so that the operator can use his feet to penetrate the gas drill rod into the soil to a certain depth for deep loosening operations.

[0025] In the above technical solution, the angle adjustment device is installed above the handheld operating device, which can manually adjust the angle of the inner layer rod of the orchard gas explosion deep loosening machine, so that the inner and outer layer air outlets are staggered to achieve the purpose of opening and closing the air outlet.

[0048] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0049] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0050] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.

The dual-mode orchard gas explosion deep loosening machine according to claim 1, characterized in that: The self-closing soil penetration device is designed based on fluid mechanics and soil dynamics, and can penetrate the soil with less resistance; it adopts an inner and outer double-layer pipe design, and the inner and outer double-layer design has multiple high-pressure gas outlets. The angle of the inner layer rod is adjusted by an angle adjustment device to control the opening and closing of the outlet. When the inner and outer double-layer outlets overlap, high-pressure gas is ejected; when the inner and outer double-layer outlets are misaligned, the outlet is closed, thereby preventing soil from entering the interior of the gas explosion deep loosening machine and causing blockage during the process of penetrating the soil.
