Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep loosening shovel technology, specifically to a multi-angle deep loosening shovel that mimics root growth. Background Technology
[0002] Medicinal herbs thrive in loose, well-aerated soil. However, prolonged tilling and other operations can create a plow pan, hindering root growth and water infiltration, and exacerbating soil erosion. Deep tillage can break up the plow pan and improve soil structure, but traditional deep tillage shovels suffer from high tillage resistance, high energy consumption, and severe soil adhesion. Meanwhile, with the expansion of medicinal herb cultivation, labor shortages are becoming increasingly prominent, necessitating efficient mechanized equipment. The multi-angle deep tillage shovel, mimicking root growth, has emerged to address this need. Drawing on biomimetic principles, it aims to reduce tillage resistance, improve soil aeration, create a favorable environment for medicinal herb growth, and increase planting efficiency and yield.
[0003] Utility model patent CN217790170U discloses an adjustable soil deep tillage mechanism for a deep tillage machine. The fixed sleeve is square, with its left side fixedly connected to the machine frame. A stop block is located above it, and a connecting shaft rotatably passes through the center of the stop block. The upper end of the connecting shaft is located above the stop block and concentrically fixed to a rotating block. The lower end is located inside the fixed sleeve and concentrically fixed to a circular connecting plate. The connecting plate is rotatably connected to the stop block via a turntable bearing on its upper surface. The adjusting block is hollow and slidably positioned inside the fixed sleeve. A connecting block is concentrically fixed at the center of its upper end, and a threaded screw passes through the center of the connecting block. The upper end of the screw is perpendicularly fixed to the center of the lower surface of the connecting plate, and the lower end is located inside the adjusting block via the connecting block. The shovel handle is inclined and located directly below the adjusting block. Its upper end is fixedly connected to the adjusting block, and its lower end is detachably equipped with a deep tillage shovel. This utility model has the advantages of good performance and precise and convenient adjustment.
[0004] Although the adjustable soil subtilizing mechanism of this subtilist is effective and offers precise and convenient adjustment, it still has the following problems in practical use: the vertical height of the subtilizing shovel can only be adjusted via the screw, and the subtilizing angle cannot be changed; the working direction is singular; and it relies entirely on manual adjustment of the screw to change the depth, making it impossible to dynamically adjust according to real-time soil conditions, which can easily lead to jamming or uneven subtilizing depth. Therefore, we propose a multi-angle subtilizing shovel that mimics root growth. Utility Model Content

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] Please see Figures 1-3 The multi-angle deep loosening shovel, which mimics root growth, includes a shovel handle 1. A shovel plate 2 is fixedly connected to the bottom end of the shovel handle 1. Shovel wings 3 are hinged to the two opposite side walls at the lower end of the shovel handle 1. An adjustment component 4 for synchronously adjusting the tilt angle of the two shovel wings 3 is also installed on the shovel handle 1. The adjustment component 4 includes two base plates 41 that are slidably connected to the shovel handle 1 and an electric push rod 44 that is fixedly installed on the outside of one side wall of the shovel handle 1. A connecting rod 5 is hinged between the base plate 41 and the shovel wing 3 on the same side.
[0034] In this embodiment, as Figure 1 As shown, a number of connection hole groups 12 for connecting to external agricultural machinery are opened through near the top. Each connection hole group 12 includes two connection holes to enhance the fixing ability and prevent the device from falling off during operation. The number of connection hole groups 12 is at least three and is linearly and equidistantly distributed from top to bottom, which can be adapted to different models of external agricultural machinery and enhance versatility.
[0035] Furthermore, such as Figure 1 As shown, the shovel plate 2 is curved and the bottom of the shovel plate 2 is bent toward the side wall away from the shovel handle 1. The concave surface of the shovel plate 2 is the shovel blade 21. The thickness of the shovel blade 21 gradually decreases from top to bottom. The curved design reduces the resistance to soil entry, and the gradually thinning shovel blade improves the soil breaking ability, making it suitable for deep loosening operations.
[0036] Furthermore, such as Figure 1 and Figure 3 As shown, two base plates 41 are symmetrically distributed on the two opposite side walls of the handle 1. The top surfaces of the two base plates 41 are integrally formed with side plates 42 at the ends that are close to each other. The two side plates 42 are connected by sliding bolts 43 to ensure that the two base plates 41 can slide synchronously. The telescopic rod end of the electric push rod 44 is fixedly connected to the top surface of the corresponding base plate 41 on the same side, which is used to drive the two base plates 41 to automatically rise and fall.
[0037] It is important to note that, such as Figure 1As shown, a groove 11 is opened through the center of the handle 1. The width of the groove 11 is greater than or equal to the diameter of the stud section of the sliding bolt 43. The two base plates 41 are simultaneously slidably connected to the groove 11 by the sliding bolt 43. The angle of the blade 3 is adjusted by the connecting rod 5 driven by the sliding of the base plates 41.
[0038] In this embodiment, as Figure 2 As shown, a strain gauge force sensor 31 is embedded in the bottom surface of the end of the shovel wing 3 away from the shovel handle 1 to detect the force on the shovel wing 3. A microcontroller 32 is embedded and fixedly installed in the side wall of the shovel wing 3 to receive the data transmitted by the strain gauge force sensor 31 and transmit the analyzed and processed data to the adjustment component 4 to automatically adjust the angle of the shovel wing 3.
[0039] Furthermore, such as Figure 2 As shown, the tip of the shovel wing 3 away from the hinge end is connected to the arrow plate 33 via the strain spring 34. The sensing element of the strain gauge force sensor 31 is fixedly connected to one end of the strain spring 34. Several rubber pads 35 are also provided between the arrow plate 33 and the shovel wing 3. The arrow plate 33 is connected to the shovel wing 3 via the strain spring 34. With the help of the rubber pads 35, the detection accuracy of the strain gauge force sensor 31 is improved.
[0040] It is worth mentioning that, such as Figure 1 As shown, the microcontroller 32 is connected to the strain gauge force sensor 31 and the electric push rod 44 via signal lines. The microcontroller 32, the strain gauge force sensor 31, and the electric push rod 44 are all electrically connected to the power supply of the external agricultural machinery via wires. The strain gauge force sensor 31 detects the force on the arrow plate 33. The microcontroller 32 receives the sensing data and analyzes and processes it. Based on the force feedback, it automatically controls the electric push rod 44 to adjust the angle of the shovel wing 3 and provides integrated power to the device through the power supply of the agricultural machinery.
[0041] Finally, it should be noted that the microcontroller 32, strain gauge force sensor 31, electric push rod 44 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.
[0042] Working principle: In this embodiment, the multi-angle deep loosening shovel that mimics root growth is first connected to an external agricultural machine via the shovel handle 1. The curved shovel plate 2 at the bottom is used for basic deep loosening. The shovel wings 3, which are hinged on both sides, can change their tilt angle under the action of the adjustment component 4. Specifically, the electric push rod 44 drives two symmetrically distributed base plates 41 to slide along the slide groove 11 of the shovel handle 1. The angle of the shovel wings 3 is adjusted synchronously through the connecting rod 5 between the base plates 41 and the shovel wings 3. When the arrow plate 33 at the end of the shovel wings 3 is subjected to soil resistance, the deformation of the strain spring 34 is sensed by the strain gauge force sensor 31. After the signal is processed by the microcontroller 32, it can control the action of the electric push rod 44 to realize the automatic adjustment of the angle of the shovel wings 3 according to the soil resistance, thereby simulating the root growth mode for multi-angle deep loosening and improving the adaptability of the operation.
[0043] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
