Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and more specifically to a pre-planting mixing treatment device. Background Technology

[0002] In modern agricultural production, pre-sowing preparations have a significant impact on crop growth and final yield. Traditional planting hole preparation methods typically include steps such as manual or mechanical hole preparation, fertilization, and soil-fertilizer mixing. Existing pre-planting treatment devices mostly employ fixed or single-mode operation, completing only one process, resulting in low efficiency.

[0003] In summary, existing technologies suffer from low efficiency because they often employ fixed or single motion modes, allowing only a single process to be completed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a pre-planting mixing and treatment device. This device addresses the technical problem of low efficiency caused by the use of fixed or single movement modes, which limit the completion of only one process. By designing a mixing and treatment device that can be fixed on a micro-tiller, the device enables the continuous and simultaneous completion of three processes: hole preparation, application of base fertilizer, and uniform mixing of soil and fertilizer. This facilitates subsequent crop sowing or transplanting operations and improves operational efficiency.

[0005] To address the aforementioned problems, this application provides a pre-planting mixing treatment device, comprising: a motion mechanism connected to a micro-tiller via a frame, wherein the micro-tiller provides power to the motion mechanism for power transmission; and a working mechanism, wherein the power gear of the working mechanism is fixed to the outer cylinder of the motion mechanism, and the sun gear and planetary carrier of the working mechanism are respectively connected to the inner cylinder of the motion mechanism for power transmission between the motion mechanism and the working mechanism. The working mechanism is used to prepare planting holes, apply fertilizer, and mix soil and fertilizer before sowing the target crop. Based on a preset interval, the motion mechanism moves the working mechanism to a working position at a preset speed and direction, wherein the preset direction is from left to right. After the working mechanism reaches the working position, it sequentially performs preparation of planting holes, fertilization, and soil-fertilizer mixing at the working position until the soil-fertilizer mixture evenly covers the bottom of the planting hole.

[0006] Furthermore, the motion mechanism includes:

[0007] The machine includes a frame, the first surface of which is fixed to the micro-tiller; a swing connecting frame, which is connected to the second surface of the frame via a first revolute joint at the center of a T-shape, and connected to the outer cylinder via a first sliding joint; a connecting rod, one end of which is connected to the two ends of the top of the swing connecting frame via a second revolute joint, and the other end of which is connected to one end of the outer cylinder connecting rod via a third revolute joint; and an outer cylinder connecting rod, the other end of which is connected to the top of the outer cylinder via a fourth revolute joint, and connected to the inner cylinder connecting rod at any position between the two ends of the outer cylinder connecting rod via a fifth revolute joint. The system comprises: a power crank, one end of which is connected to the frame via a sixth revolute joint, and the other end of which is connected to the outer cylinder via a seventh revolute joint, for driving the outer cylinder to perform a first cycloidal motion; an outer cylinder, which is connected to the inner cylinder via a second prismatic joint; an inner cylinder, which performs a second cycloidal motion under the combined action of the outer cylinder, the outer cylinder connecting rod, and the inner cylinder connecting rod, wherein the second cycloidal motion has the same cycloidal phase and the same linear direction as the first cycloidal motion, but different speeds; and an inner cylinder connecting rod, which drives the inner cylinder to perform the second cycloidal motion.

[0008] Furthermore, the operating mechanism includes:

[0009] A power gear mounting bracket is fixed to the outer cylinder according to a preset fixing method to fix the power gear; the power gear is connected to the power gear mounting bracket through an eighth rotary joint and transmits power after the outer cylinder moves through a flexible steel wire shaft; a power gear ring meshes with the power gear and is fixedly connected to the drilling drill connecting flange for power transmission; the drilling drill connecting flange is connected to the outer cylinder through a ninth rotary joint; a planetary gear stirring gear ring connecting flange is bolted to the drilling drill connecting flange; and the planetary gear stirring gear ring is connected to the drilling drill through the planetary gear stirring gear ring connecting flange. The system includes: a flange fixed connection; a ditch drill, fixedly connected to the power gear ring, used to divide the soil at the work station into a first soil area and a second soil area, wherein the first soil area is located inside the hollow ditch drill, and the second soil area is discharged to the surrounding area through the ditch cutter to form pits; a ditch cutter, fixedly connected to the ditch drill; a planetary stirring claw, fixedly connected to a stirring planetary wheel; a stirring planetary wheel, meshing with the planetary wheel stirring gear ring, and moving relative to the planetary wheel stirring gear ring through a third sliding pair; a sun gear, one surface of which is fixedly connected to the inner cylinder, and one end face meshing with the stirring planetary wheel; and a planetary carrier, connected to the inner cylinder through a fourth sliding pair.

[0010] Furthermore, when the outer cylinder moves to the first position under the drive of the power crank, the inner cylinder is in the second position. The first position is the lowest position that the outer cylinder can reach when performing the first cycloidal motion, and the second position is the lowest position that the inner cylinder can reach when performing the second cycloidal motion. The first position is lower than the second position.

[0011] When the outer cylinder moves to the third position under the drive of the power crank, the inner cylinder is in the fourth position. The third position is the highest position that the outer cylinder can reach when performing the first cycloidal motion, and the fourth position is the highest position that the inner cylinder can reach when performing the second cycloidal motion. The third position is higher than the fourth position.

[0012] Furthermore, when the flexible steel wire shaft transmits the power from the movement of the outer cylinder to the power gear fixing frame, it drives the power gear ring, the drilling connection flange, the planetary gear stirring gear ring connection flange, and the planetary gear stirring gear ring to rotate.

[0013] Furthermore, by rotating the flange of the drilling drill, the drilling drill and the drilling tool are driven to rotate, forming soil in the first area and soil in the second area.

[0014] Furthermore, when the planetary gear stirring ring rotates, the stirring planetary gear rotates through meshing with the planetary gear stirring ring, and drives the planetary stirring claw to mix the soil in the first area with the fertilizer applied by the intermittent fertilization device to form a soil-fertilizer mixture.

[0015] Furthermore, when the inner cylinder moves up and down relative to the outer cylinder, it drives the sun gear, planetary carrier, stirring planetary gear, and planetary stirring claw to move up and down, and uses the planetary stirring claw to break up and separate the soil-fertilizer mixture.

[0016] Furthermore, the device also includes:

[0017] An image acquisition device is deployed to acquire images of the planting holes after the working mechanism has completed its work, thereby obtaining a set of planting hole images. A hybrid evaluation network layer is used to evaluate the set of planting hole images to obtain a first evaluation result. It is then determined whether the first evaluation result meets a preset evaluation threshold. If not, an early warning instruction is generated, and the working mechanism and the motion mechanism are corrected according to the early warning instruction.

[0018] The pre-planting mixing treatment device provided in this specification has the following characteristics: When the motion mechanism is working, the power crank rotates clockwise, and the outer cylinder drives the working mechanism to perform a cycloidal motion under this combined motion. Meanwhile, the inner cylinder, under the combined action of the outer cylinder, the outer cylinder connecting rod, and the inner cylinder connecting rod, performs a motion similar in trend to the outer cylinder but with different details. When the working mechanism is working, the power gear inputs power through a flexible steel shaft, driving the power gear ring, the drilling drill connecting flange, the planetary gear stirring gear ring, and the planetary gear stirring gear ring to rotate. This causes the stirring planetary gears to drive the stirring planetary claws to rotate on their own axis while revolving around the center. This process thoroughly mixes the soil and fertilizer mixture. When the inner cylinder moves up and down relative to the outer cylinder under the drive of the motion mechanism, it drives the sun gear, planetary carrier, stirring planetary gear, and planetary stirring claw to move up and down. This causes the deep-drilling hole at the end of the planetary stirring claw to break up and separate the soil and fertilizer mixture, so that the soil and fertilizer mixture is evenly distributed at the bottom of the pit, thus completing the fertilization operation. By optimizing the structure of the existing device, the three processes of pit making, base fertilizer application, and uniform mixing of soil and fertilizer are carried out simultaneously and continuously, achieving the technical effect of improving the automation level and efficiency of the operation.

[0029] This application provides a pre-planting mixing and treatment device to solve the technical problem of low efficiency caused by the use of fixed or single movement modes in existing technologies, which can only complete a single process. By designing a mixing and treatment device that can be fixed on a micro-tiller, the three processes of hole preparation, base fertilizer application, and uniform mixing of soil and fertilizer are completed continuously and synchronously, which facilitates subsequent crop sowing or transplanting operations and achieves the technical effect of improving work efficiency.

[0030] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 This application provides a pre-planting mixing treatment device, comprising:

[0031] The motion mechanism 10 is connected to the mini-tiller via a frame 11, and the mini-tiller provides power to the motion mechanism for power transmission.

[0032] The working mechanism 20 has a power gear 22 fixed to the outer cylinder 16 of the motion mechanism 10, and the sun gear 211 and planet carrier 212 of the working mechanism 20 are respectively connected to the inner cylinder 17 of the motion mechanism 10 to transmit power between the motion mechanism 10 and the working mechanism 20. The working mechanism is used to prepare planting holes, apply fertilizer, and mix soil fertilizer in the planting holes before sowing the target crop.

[0033] Based on a preset interval period, the motion mechanism 10 is used to move the working mechanism 20 to the working position at a preset speed in a preset direction, wherein the preset direction is from left to right; after the working mechanism 20 moves to the working position, the pit is dug, fertilizer is applied and soil and fertilizer are mixed in sequence at the working position until the soil and fertilizer mixture is evenly distributed at the bottom of the pit.

[0034] Specifically, this application provides a pre-planting mixing treatment device, which consists of two parts: a motion mechanism 10 and a working mechanism 20. The device is powered by a mini-tiller, connected to the mini-tiller via the frame 11 of the motion mechanism 10, and powered by the mini-tiller.

[0035] The motion mechanism is connected to the micro-tiller via the frame 11, fixing the device to the micro-tiller. The micro-tiller provides power to the motion mechanism for power transmission, assisting the working mechanism 20 in preparing planting holes, applying fertilizer, and mixing soil fertilizer before sowing the target crop. The power gear 22 of the working mechanism is fixed to the outer cylinder 16 of the motion mechanism 10, and the sun gear 211 of the working mechanism 20 is fixedly connected to the inner cylinder 17 of the motion mechanism 10. The planetary carrier 212 is connected to the inner cylinder 17 of the motion mechanism 10 via a revolute joint, enabling power transmission between the motion mechanism 10 and the working mechanism 20.

[0036] When the working mechanism 20 is working, the power gear 22 inputs power through the steel wire flexible shaft. When the inner cylinder 17 moves up and down relative to the outer cylinder 16 under the drive of the motion mechanism 10, it will drive the sun gear 211 and the planetary carrier 212 to move up and down, breaking up and separating the soil-fertilizer mixture, so that the soil-fertilizer mixture is evenly distributed at the bottom of the pit.

[0037] Further details are attached. Figure 2 As shown, the motion mechanism includes:

[0038] Frame 11, the first surface of which is fixed to the micro-tiller;

[0039] The swing connecting frame 12 is connected to the second surface of the frame 11 through a first rotating joint at the center of the T-shape, and the swing connecting frame 12 is connected to the outer cylinder 16 through a first sliding joint.

[0040] The connecting rod 13 has one end connected to the two ends of the top of the swing connecting frame 12 via a second rotary joint, and the other end connected to one end of the outer cylinder connecting rod 14 via a third rotary joint.

[0041] The outer cylinder connecting rod 14, the other end of which is connected to the top of the outer cylinder 16 through a fourth rotary joint, and connected to the inner cylinder connecting rod 18 at any position between the two ends of the outer cylinder connecting rod 14 through a fifth rotary joint;

[0042] A power crank 15, one end of which is connected to the frame 11 via a sixth rotary joint, and the other end of which is connected to the outer cylinder 16 via a seventh rotary joint, is used to drive the outer cylinder 16 to perform a first cycloidal motion.

[0043] Outer cylinder 16, which is connected to inner cylinder 17 via a second sliding joint;

[0044] The inner cylinder 17 undergoes a second cycloidal motion under the combined action of the outer cylinder 16, the outer cylinder connecting rod 14, and the inner cylinder connecting rod 18. The second cycloidal motion has the same cycloidal phase and the same linear motion direction as the first cycloidal motion, but the speeds are different.

[0045] Inner cylinder connecting rod 18, which is used to drive the inner cylinder 17 to perform a second cycloidal motion.

[0046] Specifically, the motion mechanism includes a frame 11, a swing connecting frame 12, a connecting rod 13, an outer cylinder connecting rod 14, a power crank 15, an outer cylinder 16, and an inner cylinder connecting rod 18. The motion mechanism 10 is responsible for intermittently moving the working mechanism 20 to the working position, achieving the effect of continuous movement of the whole machine while the mechanism operates intermittently.

[0047] The first surface of the frame 11 is fixed to the micro-tiller. The swing connecting frame 12 is a T-shaped structure. The swing connecting frame 12 is connected to the second surface of the frame 11 through a first revolute joint at the center of the T-shape, allowing the swing connecting frame 12 to rotate around the rotation axis of the first revolute joint. The frame 11 is a flat cuboid structure, with the first and second surfaces being two opposing surfaces, as shown in the attached figure. Figure 2The surface shown that is connected to the swing connecting frame 12 is the second surface, and the opposite surface is the first surface. The swing connecting frame 12 is connected to the outer cylinder 16 through a first sliding joint, so that the outer cylinder 16 can swing.

[0048] One end of the connecting rod 13 is connected to the two ends of the top of the swing connecting frame 12 via a second revolute joint. The top of the swing connecting frame 12 has three ends, and the two ends located at the edge are connected to the connecting rod 13 via the second revolute joint. Figure 2 As can be seen, the connecting rod 13 is a symmetrical structure, meaning there are two symmetrical connecting rods. The upper end of each connecting rod is connected to one of the two endpoints located at the edge, and the other end is connected to one end of the outer cylinder connecting rod 14 through a third revolute joint. The movement of the connecting rod 13 and the outer cylinder connecting rod 14 drives the movement of the outer cylinder 16.

[0049] The other end of the outer cylinder connecting rod 14 is connected to the top of the outer cylinder 16 via a fourth revolute joint, and is connected to the inner cylinder connecting rod 18 at any position between the two ends of the outer cylinder connecting rod 14 via a fifth revolute joint. One end of the power crank 15 is connected to the frame 11 via a sixth revolute joint, and the other end of the power crank 15 is connected to the outer cylinder 16 via a seventh revolute joint. The power crank 15 rotates clockwise, driving the outer cylinder 16 to perform a first cycloidal motion.

[0050] The outer cylinder 16 is connected to the inner cylinder 17 via a second sliding joint. Under the combined action of the outer cylinder 16, the outer cylinder connecting rod 14, and the inner cylinder connecting rod 18, the inner cylinder 17 undergoes a second cycloidal motion. The inner cylinder connecting rod 18 drives the inner cylinder 17 to perform this second cycloidal motion. The second cycloidal motion has the same cycloidal phase and linear direction as the first cycloidal motion, but different speeds. That is, under the combined action of the outer cylinder 16, the outer cylinder connecting rod 14, and the inner cylinder connecting rod 18, the inner cylinder 17 moves in a manner similar to that of the outer cylinder but with different details. In other words, the swing phase is the same, the direction of linear motion is the same, but the speed is different. For example, when the outer cylinder 16 moves to the lowest position of the coordinate system with the earth as the reference under the drive of the power crank 15, the inner cylinder 17 is also at the lowest position of this coordinate system, but at the highest position relative to the outer cylinder 16; when the outer cylinder 16 moves to the highest position of the coordinate system with the earth as the reference under the drive of the power crank 15, the inner cylinder 17 is also at the highest position of this coordinate system, but at the lowest position relative to the outer cylinder 16, so as to realize the key operation procedures of the working mechanism, namely, digging holes, fertilizing, and soil-fertilizer mixing.

[0051] Furthermore, such as Figure 3 As shown, the working mechanism 20 includes:

[0052] A power gear fixing bracket 21 is fixed to the outer cylinder 16 according to a preset fixing method and is used to fix the power gear 22.

[0053] The power gear 22 is connected to the power gear fixing frame 21 through the eighth rotary joint, and transmits power after the outer cylinder moves through the steel wire flexible shaft.

[0054] The power gear ring 23 meshes with the power gear 22 and is fixedly connected to the drilling connection flange 24 for power transmission.

[0055] The drilling drill connecting flange 24 is connected to the outer cylinder 16 via a ninth rotary joint;

[0056] Planetary gear stirring ring connecting flange 25 is connected to the hole drilling connecting flange 24 by bolts;

[0057] Planetary gear stirring ring 26, which is fixedly connected to the hole drilling connecting flange 24 via planetary gear stirring ring connecting flange 25;

[0058] The drilling drill 27 is fixedly connected to the power gear ring 23 and is used to divide the soil at the working position into a first area of ​​soil and a second area of ​​soil. The first area of ​​soil is located inside the hollow drilling drill, and the second area of ​​soil is discharged to the surrounding area through the drilling tool to form a pit.

[0059] A baiting tool 28 is fixedly connected to the baiting drill 27;

[0060] Planetary stirring claw 29, which is fixedly connected to the stirring planetary wheel 210;

[0061] A stirring planetary gear 210 meshes with a planetary gear stirring ring 26 and moves in a linear motion relative to the planetary gear stirring ring 26 via a third sliding pair.

[0062] Sun gear 211, one surface of which is fixedly connected to the inner cylinder 17, and one end face of which meshes with the stirring planetary gear 210;

[0063] Planetary carrier 212 is connected to the inner cylinder 17 via a fourth sliding joint.

[0064] Specifically, the operating mechanism is responsible for completing the intermittent synchronous "drilling, fertilizing, and soil-fertilizer mixing" work of the entire machine. The power gear fixing frame 21 is fixed to the outer cylinder 16 according to a preset fixing method, which can be a fixed connection or a detachable connection, and is used to fix the power gear 22. The power gear 22 is connected to the power gear fixing frame 21 through an eighth rotary joint, and transmits power after the outer cylinder moves through a steel wire flexible shaft, that is, inputs power through the steel wire flexible shaft.

[0065] The power gear ring 23 is meshed with the power gear 22, and the power gear ring 23 is fixedly connected to the drilling connection flange 24 for power transmission. When the power gear 22 rotates, the power gear ring 23 will also rotate accordingly due to the meshing of the teeth. This meshing connection ensures that power is transmitted from the power gear 22 to the power gear ring 23.

[0066] The power gear ring 23 is fixedly connected to the drilling drill connecting flange 24. The drilling drill connecting flange 24 is a component used to connect the drilling drill, and it usually has an interface that matches the drilling drill. The power gear ring 23 and the drilling drill connecting flange 24 are tightly connected together by a fixed connection method (such as bolt connection, welding, etc.), ensuring that the rotational force of the power gear ring 23 can be directly transmitted to the drilling drill connecting flange 24, thereby driving the drilling drill to work. When the external power source, the micro-tiller, drives the power gear 22 to rotate, the power gear ring 23, which is meshed with it, will also start to rotate. Due to the fixed connection between the power gear ring 23 and the drilling drill connecting flange 24, the drilling drill connecting flange 24 will also rotate with the power gear ring 23. Finally, the drilling drill or other rotating tools connected to the drilling drill connecting flange 24 will be subjected to rotational force and begin to work.

[0067] Specifically, the drilling drill connecting flange 24 is connected to the outer cylinder 16 via a ninth rotary joint, and the drilling drill connecting flange 24 rotates relative to the outer cylinder 16. The planetary gear stirring ring connecting flange 25 is bolted to the drilling drill connecting flange 24, allowing for easy disassembly and replacement, and providing a connection point for the planetary gear stirring ring 26. The planetary gear stirring ring 26 is fixedly connected to the drilling drill connecting flange 24 via the planetary gear stirring ring connecting flange 25, thereby transmitting power or serving as a support structure, meshing with the stirring planetary gear 210, and participating in the movement of the planetary gear system.

[0068] The drilling drill 27 is fixedly connected to the power gear ring 23, receiving rotational power through the power gear ring 23. When the power gear ring 23 rotates, the drilling drill 27 also rotates synchronously. The drilling cutter 28 is fixedly connected to the drilling drill 27. When the drilling drill 27 starts to rotate, the drilling cutter 28 contacts and cuts the soil, dividing the soil at the working position into a first area and a second area. The soil in the first area is sucked into the interior of the drilling drill 27, while the soil in the second area is pushed to the surrounding area. The drilling cutter 28 is fixedly connected to the drilling drill 27, and it also rotates as the drilling drill 27 rotates. The rotation of the drilling cutter 28 allows it to expel the soil from the second area to the surrounding area, thereby forming a pit on the ground.

[0069] The planetary mixing claw 29 is fixedly connected to the mixing planetary wheel 210. Any rotational movement of the mixing planetary wheel 210 will cause the planetary mixing claw 29 to rotate as well. The main function of the planetary mixing claw 29 is to mix or turn over the soil. The planetary wheel mixing gear ring 26 is a fixed or rotating gear ring that meshes with the mixing planetary wheel 210. It provides tooth surfaces that mesh with the mixing planetary wheel 210. The meshing of the mixing planetary wheel 210 and the planetary wheel mixing gear ring 26 allows the mixing planetary wheel 210 to perform relative linear motion with the planetary wheel mixing gear ring 26.

[0070] The sun gear 211 is typically a central gear, with one surface fixedly connected to the inner cylinder 17. The sun gear 211 and the inner cylinder 17 move synchronously. One end face meshes with the stirring planetary gear 210. When the sun gear 211 rotates, it drives the meshing stirring planetary gear 210 to move. The planet carrier 212 is connected to the inner cylinder 17 via a fourth sliding joint, allowing the planet carrier 212 to move or adjust its position on the inner cylinder 17 in a certain direction.

[0071] Furthermore, the device also includes:

[0072] When the outer cylinder moves to the first position under the drive of the power crank, the inner cylinder is in the second position. The first position is the lowest position that the outer cylinder can reach when performing the first cycloidal motion, and the second position is the lowest position that the inner cylinder can reach when performing the second cycloidal motion. The first position is lower than the second position.

[0073] When the outer cylinder moves to the third position under the drive of the power crank, the inner cylinder is in the fourth position. The third position is the highest position that the outer cylinder can reach when performing the first cycloidal motion, and the fourth position is the highest position that the inner cylinder can reach when performing the second cycloidal motion. The third position is higher than the fourth position.

[0074] When the motion mechanism 10 is working, the power crank 15 rotates clockwise. Under this combined motion, the outer cylinder 16 moves to the first position. Meanwhile, the inner cylinder 17, under the combined action of the outer cylinder 16, the outer cylinder connecting rod 14, and the inner cylinder connecting rod 18, performs a motion similar in trend to the outer cylinder but with different details. That is, the oscillation phase is the same, the linear motion direction is the same, but the speed is different, placing it in the second position. The first position is the lowest position the outer cylinder can reach during the first cycloidal motion, and the second position is the lowest position the inner cylinder can reach during the second cycloidal motion. The first position is lower than the second position. In other words, the second cycloidal motion has the same cycloidal phase and linear motion direction as the first cycloidal motion, but the speed is different. For example, when the outer cylinder 16 moves to the lowest position in a coordinate system with the ground as the reference point under the drive of the power crank 15, the inner cylinder 17 is also at the lowest position in this coordinate system, but at the highest position relative to the outer cylinder 16.

[0075] When the outer cylinder 16 moves to the third position under the drive of the power crank 15, the inner cylinder 17 is in the fourth position. The third position is the highest position the outer cylinder can reach during the first cycloidal motion, and the fourth position is the highest position the inner cylinder can reach during the second cycloidal motion. The third position is higher than the fourth position. For example, when the outer cylinder 16 moves to the highest position in a coordinate system with the ground as the reference point under the drive of the power crank 15, the inner cylinder 17 is also at the highest position in this coordinate system, but at its lowest position relative to the outer cylinder 16, to achieve the key operational steps of the working mechanism, namely, baiting, fertilizing, and soil-fertilizer mixing.

[0076] Furthermore, the device also includes:

[0077] When the flexible steel wire shaft transmits the power from the movement of the outer cylinder 16 to the power gear fixing frame 21, it drives the power gear ring 23, the drilling connection flange 24, the planetary gear stirring gear ring connection flange 25, and the planetary gear stirring gear ring 26 to rotate.

[0078] Specifically, the flexible steel wire shaft, due to its flexibility and bendability, can flexibly connect different devices or components and transmit power from one point to another. In this application, the flexible steel wire shaft transmits the power generated by the movement of the outer cylinder 16 to the power gear holder 21. As a key component for power transmission, the power gear holder 21 can stably receive the power transmitted by the flexible steel wire shaft. When the power gear holder 21 receives power, it drives the connected power gear ring 23 to start rotating. The drilling drill connecting flange 24, the planetary gear mixing gear ring connecting flange 25, and the planetary gear mixing gear ring 26, which are connected to the power gear ring 23, will also start rotating due to their meshing with the power gear ring or other components, facilitating subsequent pre-planting drilling, fertilization, and soil-fertilizer mixing.

[0079] Furthermore, the device also includes:

[0080] The rotation of the drilling drill connecting flange 24 causes the drilling drill 27 and the drilling cutter 28 to rotate, forming soil in the first area and soil in the second area.

[0081] Specifically, the rotation of flange 24 of the burrowing drill directly drives the burrowing drill 27 to rotate. The burrowing drill 27 is used to create holes or "pits" in the soil. The end of the burrowing drill 27 is typically equipped with a burrowing cutter 28, which cuts and breaks up the soil during rotation, thus helping to form the desired soil structure. As the burrowing drill 27 and the burrowing cutter 28 rotate, the soil is cut, broken up, and rearranged, forming two distinct areas. One part, located inside the hollow burrowing drill (the first area), is used for subsequent mixing with fertilizer; the other part is swept away by the burrowing cutter and discharged in all directions, thus forming pits, the second area of ​​soil.

[0082] Furthermore, the device also includes:

[0083] When the planetary gear stirring ring 26 rotates, the stirring planetary gear 210 rotates through meshing with the planetary gear stirring ring 16, and drives the planetary stirring claw 29 to mix the soil in the first area with the fertilizer applied by the intermittent fertilization device to form a soil-fertilizer mixture.

[0084] Specifically, when the planetary gear agitator ring 26 begins to rotate, it, as a key component for power transmission, transmits the rotational power to its meshing component, namely, the agitating planetary gear 210. The agitating planetary gear 210 meshes with the corresponding gear on the planetary gear agitator ring 26 through its gears. When the planetary gear agitator ring 26 rotates, the agitating planetary gear 210 also rotates due to the meshing action. The agitating planetary gear 210 is usually equipped with planetary agitating claws 29, which rotate along with the agitating planetary gear 210, mixing the soil and fertilizer together. At the same time, the intermittent fertilization device will, according to the set program or the operator's instructions, periodically or quantitatively add fertilizer to the soil. This fertilizer is added to the working area of ​​the planetary agitating claws. As the planetary agitating claws 29 rotate, they mix the surrounding soil with the fertilizer, making the fertilizer evenly distributed in the soil, forming a soil-fertilizer mixture, providing a good soil environment for plant growth.

[0085] Furthermore, the device also includes:

[0086] When the inner cylinder 16 moves up and down relative to the outer cylinder 17, it drives the sun gear 211, planetary carrier 212, stirring planetary gear 210, and planetary stirring claw 29 to move up and down, and uses the planetary stirring claw 29 to break up and separate the soil-fertilizer mixture.

[0087] Specifically, when the inner cylinder 16 moves up and down relative to the outer cylinder 17, this relative motion is transmitted to components directly or indirectly connected to the inner cylinder, namely, driving the sun gear 211, planetary carrier 212, stirring planetary gear 210, and planetary stirring claws 29 to move up and down. As the planetary stirring claws 29 move up and down, they act on the soil-fertilizer mixture. This action is not limited to stirring; it also includes breaking up and separating the already mixed soil and fertilizer, helping to ensure a more uniform mixture and avoiding areas with too much or too little fertilizer. This is beneficial for plant absorption and utilization of the fertilizer.

[0088] Furthermore, the device also includes:

[0089] An image acquisition device is deployed to acquire images of the planting holes after the working mechanism 20 has completed its work, thereby obtaining a set of planting hole images. The set of planting hole images is evaluated using a hybrid evaluation network layer to obtain a first evaluation result. It is then determined whether the first evaluation result meets a preset evaluation threshold. If not, an early warning instruction is generated, and the working mechanism 10 and the motion mechanism 20 are corrected according to the early warning instruction.

[0090] Specifically, one or more image acquisition devices, such as cameras, are deployed in the work area (e.g., farmland) to ensure clear images of the planting holes after the work is completed. These devices capture images of the planting holes after the work is finished. Image acquisition can be real-time or periodic, depending on the actual work frequency and monitoring needs. The acquired images form a set of planting hole images for subsequent quality evaluation. This set of images is then input into a hybrid evaluation network layer for evaluation. This hybrid evaluation network layer, built based on existing deep learning models or image recognition algorithms, automatically analyzes the image features of the planting holes, such as soil color, structure, and fertilizer distribution. By analyzing these features, the hybrid evaluation network layer can assess the quality of the planting holes and generate a first evaluation result. Specifically, planting hole image samples can be collected using existing technology and corresponding quality evaluation samples can be configured as training data. The hybrid evaluation network layer is then trained using existing deep learning models or image recognition algorithms. This is a common technique used by those skilled in the art and will not be elaborated upon here.

[0091] The first evaluation result is compared with a preset evaluation threshold, which is set based on factors such as planting requirements and crop type. This threshold is used to determine whether the quality of the planting hole meets the standards and is set by those skilled in the art based on actual conditions. If the first evaluation result does not meet the preset evaluation threshold, it indicates that there is a problem with the quality of the planting hole and correction is required. At this time, an early warning instruction is generated. Based on the early warning instruction, the operating mechanism and motion mechanism are corrected, including adjusting the working parameters of components such as the hole-drilling drill and the mixing claw, to ensure that they can correctly form the planting hole and mix the soil and fertilizer, thereby improving planting efficiency and quality.

[0092] This application provides a pre-planting mixing treatment device. When the motion mechanism is working, the power crank rotates clockwise, and the outer cylinder, under this combined motion, drives the working mechanism to perform a cycloidal motion. Meanwhile, the inner cylinder, under the combined action of the outer cylinder, the outer cylinder connecting rod, and the inner cylinder connecting rod, performs a motion similar in trend to the outer cylinder but with different details. When the working mechanism is working, the power gear inputs power through a flexible steel shaft, driving the power gear ring, the drilling drill connecting flange, the planetary gear mixing gear ring, and the planetary gear mixing gear ring to rotate. This causes the mixing planetary gears to drive the mixing planetary claws to rotate on their own axis while revolving around the center. The soil and fertilizer mixture is thoroughly stirred and mixed. When the inner cylinder moves up and down relative to the outer cylinder under the drive of the motion mechanism, it will drive the sun gear, planetary carrier, stirring planetary gear, and planetary stirring claw to move up and down. This causes the deep-drilling hole at the end of the planetary stirring claw to break up and separate the soil and fertilizer mixture, so that the soil and fertilizer mixture is evenly distributed at the bottom of the pit, thereby completing the fertilization operation. By optimizing the structure of the existing device, the three processes of pit making, base fertilizer application, and uniform mixing of soil and fertilizer are carried out simultaneously and continuously, achieving the technical effect of improving the automation level and efficiency of the operation.
