Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and more specifically, it relates to an agricultural soil improvement device. Background Technology

[0002] In the field of agricultural soil improvement, farmers often face problems such as uneven application of soil conditioners and asynchronous rotary tillage and fertilization in order to enhance soil fertility and improve farming conditions. At this time, an agricultural soil improvement device is needed to achieve both the application of soil conditioners and deep tillage to loosen the soil.

[0003] However, traditional soil improvement equipment lacks the structure for distributing materials and rotary tillage for fertilization. As a result, during the process of improving farmland soil, it is necessary to manually apply the soil conditioner and then perform rotary tillage separately. Furthermore, manual application lacks directional guidance and quantitative control, which can easily lead to deviations in the application range and uneven application rates. This can result in concentrated accumulation of the soil conditioner or incomplete coverage, ultimately causing uneven distribution of soil nutrients and imbalance in crop growth. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an agricultural soil improvement device to solve the technical problem that traditional improvement devices in the prior art lack material distribution and rotary tillage fertilization structures, resulting in uneven distribution of soil conditioner and unbalanced crop growth.

[0005] The purpose and effectiveness of this agricultural soil improvement device are achieved by the following specific technical means:

[0006] An agricultural soil improvement device includes a frame and a material distribution mechanism. The material distribution mechanism includes a material distribution hopper, which is fixedly installed on the top of the frame. The top of the frame is provided with a mounting box, and a first drive motor is provided inside the mounting box. The drive shaft of the first drive motor is connected to the double spiral conveying shaft inside the material distribution hopper through gears.

[0007] Both sides of the feed hopper are provided with connecting rods for connecting to the rotary tillage mechanism. The rotary tillage mechanism includes a housing and a central shaft. Both ends of the central shaft are rotatably connected to the inner sidewall of the housing. Multiple sets of rotary tillage blades are spaced apart along the axial direction of the central shaft. A pressure plate is rotatably connected to the end of the housing away from the feed hopper.

[0008] According to a preferred embodiment, a storage box is provided at the end of the material distribution hopper away from the mounting box, and a bidirectional material distribution pipe is provided at the bottom of the storage box, and the storage box is connected to the bidirectional material distribution pipe.

[0009] According to a preferred embodiment, the bidirectional material distribution pipe is provided with two sets of single spiral conveying shafts, and the two sets of single spiral conveying shafts are arranged opposite to each other. A second drive motor is provided at both ends of the bidirectional material distribution pipe, and the bidirectional material distribution pipe forms a transmission and feeding structure with the single spiral conveying shafts through the second drive motors.

[0010] According to a preferred embodiment, the outer wall of the bidirectional material distribution pipe is provided with multiple sets of discharge ports, which are spaced apart from the middle to both ends, and the diameter of the multiple sets of discharge ports gradually increases from the middle to both ends.

[0011] According to a preferred embodiment, a through groove is provided on the top of the housing, and a drive component for driving the rotary tiller blades is provided in the through groove;

[0012] The driving component includes a third driving motor, a driven gear is also sleeved on the central shaft, and a driving gear is provided on the transmission shaft of the third driving motor. The driving gear drives the driven gear through a chain.

[0013] The top of the housing is also provided with a protective cover that covers the through slot.

[0014] According to a preferred embodiment, the drive member is provided with a protective shell on its outer side for protecting the driven gear and the chain. The protective shell is embedded in the through groove, and a deep tillage shovel is provided at one end of the protective shell.

[0015] According to a preferred embodiment, one end of the frame is further provided with a three-point suspension mechanism for connection with a tractor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, through the coordinated arrangement of a rotary tillage mechanism and a distribution mechanism, enables the device to achieve integrated operation of soil rotary tillage and uniform distribution of soil conditioner. The third drive motor of the rotary tillage mechanism drives the rotary blades on the central shaft to rotate via a chain, breaking up the soil, while the deep tillage shovel further loosens the deep soil layers. The first drive motor of the distribution mechanism drives a double-helix conveyor shaft to transport the conditioner from the storage tank to the bidirectional distribution pipe. Two sets of opposing single-helix conveyor shafts, combined with discharge ports of different diameters, achieve uniform distribution of the conditioner. This integrated operation process reduces the need for separate rotary tillage and distribution steps, allowing the conditioner to fully mix with the soil. This enhances the device's operational continuity and improves its ability to perform integrated rotary tillage and soil conditioner improvement in agriculture.

[0018] 2. When using this device, it can be quickly connected to a tractor via the three-point suspension mechanism of the chassis, enabling movement with the tractor's power. This adapts to different scales of farmland operations, enhancing the device's versatility. Furthermore, the pressure plate, protective cover, and protective shell of the casing ensure operational safety and component protection. The pressure plate levels the soil after rotary tillage, while the protective cover and shell protect the drive and transmission components, preventing soil entanglement or damage from external forces. Simultaneously, the multiple discharge ports of the bidirectional material distribution pipe meet the requirements of different spreading densities. This combination optimizes the operational effect, extends the device's service life, and improves its overall performance in terms of safety and durability in agricultural soil improvement operations.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0027] Example:

[0028] like Figures 1 to 5As shown, an agricultural soil improvement device includes a frame 11 and a material distribution mechanism. The material distribution mechanism includes a material distribution hopper 12, which is fixedly installed on the top of the frame 11. The top of the frame 11 is provided with an installation box, and a first drive motor 13 is provided inside the installation box. The transmission shaft of the first drive motor 13 is connected to the double spiral conveying shaft 14 inside the material distribution hopper 12 through gears.

[0029] Both sides of the feed hopper 12 are provided with connecting rods for connecting the rotary tillage mechanism. The rotary tillage mechanism includes a housing 21 and a central shaft 22. Both ends of the central shaft 22 are rotatably connected to the inner side wall of the housing 21. The central shaft 22 is provided with multiple sets of rotary tillage blades 24 at intervals along its axial direction. A pressure plate 25 is rotatably connected to the end of the housing 21 away from the feed hopper 12.

[0030] It should be noted that the soil conditioners compatible with this equipment are primarily environmentally friendly and suitable for agricultural production, and mainly include the following three categories, which can be selected according to specific soil problems:

[0031] Well-rotted organic fertilizer: Made from livestock and poultry manure, straw, kitchen waste, etc., through high-temperature composting and fermentation, it contains no pathogens or weed seeds. It contains nitrogen, phosphorus, potassium, and trace elements, which can directly replenish soil fertility, improve soil aggregate structure, and enhance soil water and fertilizer retention capacity, making it suitable for infertile soils with low organic matter content.

[0032] Biochar-based conditioner: Made from agricultural crop straw, forestry waste, etc., through high-temperature carbonization to produce biochar, which is then combined with humic acid, amino acids, and other compounds. Its well-developed porous structure allows it to adsorb heavy metals and harmful substances in the soil, regulate soil pH, enhance soil aeration, and reduce nutrient loss.

[0033] Compound microbial inoculant: Contains beneficial microbial communities such as Bacillus, Lactic acid bacteria, and Actinomycetes, combined with a carrier substrate. After being applied to the soil, the beneficial microbial communities can inhibit the reproduction of pathogens, reduce the occurrence of soil-borne diseases, and decompose insoluble nutrients in the soil, promoting crop absorption. It is suitable for plots with continuous cropping obstacles and soil microbial community imbalance.

[0034] The aforementioned soil amendments are all in granular or powder form, with good flowability, allowing them to pass smoothly through the spiral conveying structure of the distribution hopper 12 and the bidirectional distribution pipe 17 without causing blockages. After being evenly spread onto the soil surface through multiple outlets of the bidirectional distribution pipe 17, the rotary tiller 24 quickly turns the amendment into the deep soil, avoiding the waste caused by the amendment floating on the surface and ensuring that the amendment effect reaches the root zone of the soil, meeting the needs of crop growth.

[0035] Specifically, the frame 11 has a stable structure that can withstand soil resistance and vibration during rotary tillage, providing reliable support for the overall equipment. The distribution hopper 12 has a funnel-shaped structure with a smooth inner wall to reduce soil conditioner residue. The double-helix conveying shaft 14 rotates synchronously under the drive of the first drive motor 13, evenly conveying the soil conditioner in the distribution hopper 12 backwards, avoiding local accumulation that could lead to uneven feeding.

[0036] It should be noted that the first drive motor 13 is a YE3-112M-4YE3 series three-phase asynchronous motor.

[0037] The rotary tillage mechanism is rigidly connected to the distribution hopper 12 via a connecting rod, and can simultaneously perform rotary tillage on the soil on both sides of the distribution hopper 12; multiple sets of rotary tillage blades 24 are arranged at equal intervals along the central axis 22, and the blades are made of wear-resistant alloy material, which is sharp and not easy to wear, and can break up soil clumps.

[0038] The pressure plate 25 at the end of the casing 21 is connected by a rotating shaft and can be pressed down at an angle. During operation, it flattens the soil after rotary tillage, reduces soil voids, and levels the ground surface to prepare for subsequent sowing or planting.

[0039] The material distribution hopper 12 is located at the end away from the installation box, and a storage box 16 is provided at the bottom of the storage box 16. The storage box 16 is connected to the bidirectional material distribution pipe 17.

[0040] The bidirectional material distribution pipe 17 is equipped with two sets of single spiral conveying shafts 18, which are arranged opposite to each other. Both ends of the bidirectional material distribution pipe 17 are equipped with second drive motors 19. The bidirectional material distribution pipe 17 forms a transmission and feeding structure with the single spiral conveying shafts 18 through the second drive motors 19.

[0041] like Figure 4 As shown, the outer wall of the bidirectional material distribution pipe 17 is provided with multiple sets of discharge ports, which are spaced apart from the middle to both ends, and the diameter of the multiple sets of discharge ports gradually increases from the middle to both ends.

[0042] Specifically, the storage bin 16 is used to temporarily store the soil conditioner, and its capacity is adapted to the needs of a single operation, avoiding frequent feeding and improving operation efficiency. The bidirectional distribution pipe 17 is connected to the storage bin 16, and the two sets of opposing single spiral conveying shafts 18 inside rotate in opposite directions under the drive of the second drive motor 19, synchronously conveying the conditioner to both ends of the pipe, realizing bidirectional uniform distribution.

[0043] It should be noted that the second drive motor 19 is a YE3-90S-4 type three-phase asynchronous motor.

[0044] The discharge port gradually increases in diameter from the middle to both ends, which can compensate for the pressure difference between the two ends of the pipeline, ensuring that the amount of soil amendment added to each discharge port is consistent and avoiding insufficient addition due to long conveying distance at the ends. The soil amendment is evenly sprinkled from the discharge port onto the soil surface in front of the rotary tillage mechanism, and then turned into the deep soil layer by the rotary tillage blades 24, achieving full mixing of the soil amendment with the soil and improving the soil improvement effect.

[0045] The top of the housing 21 has a through slot, and a drive component for driving the rotary tiller 24 is installed in the through slot;

[0046] like Figure 5 As shown, the driving component includes a third drive motor 26, a driven gear is also sleeved on the central shaft 22, and a driving gear is provided on the transmission shaft of the third drive motor 26. The driving gear drives the driven gear through a chain.

[0047] The top of the housing 21 is also provided with a protective cover 23 covering the through slot.

[0048] The drive unit is provided with a protective shell 27 on the outside to protect the driven gear and chain. The protective shell 27 is embedded in the through groove, and a deep tillage shovel 28 is provided at one end of the protective shell 27.

[0049] Specifically, it should be noted that the third drive motor 26 is a YE3-132S-4 type three-phase asynchronous motor. The third drive motor 26 provides sufficient power to the rotary tiller blades 24. Through the transmission cooperation of the drive gear, chain, and driven gear, it drives the central shaft 22 to rotate at high speed, thereby driving the rotary tiller blades 24 to break up the soil. The protective shell 27 is embedded in the through groove to seal and protect the gears and chain, preventing soil, weeds, and other debris from being drawn into the transmission mechanism, preventing component wear or jamming, and extending the service life of the drive components. The protective cover 23 covers the through groove to further enhance the protective effect and prevent rainwater and soil from entering. During operation, the deep tillage shovel 28 first breaks up the deep soil, and then the rotary tiller blades 24 perform fine tillage. This can increase the tillage depth and reduce the load on the rotary tiller blades 24, which is especially suitable for severely compacted soils.

[0050] like Figure 1 As shown, one end of the frame 11 is also provided with a three-point suspension mechanism 15 for connection with the tractor.

[0051] Specifically, the three-point suspension mechanism 15 adopts a standard agricultural machinery connection structure, which can be quickly connected to various types of tractors, and is easy to install and disassemble. It provides auxiliary power to the equipment via the tractor's power take-off shaft, and simultaneously utilizes the tractor's traction to move the equipment, eliminating the need for an additional power unit and reducing operating costs. During operation, the working depth of the equipment can be adjusted via the tractor to adapt to the planting needs of different crops and soil improvement depth requirements, improving the equipment's versatility.

[0052] It should be noted that the three-point suspension mechanism 15 is a common setting for agricultural machinery, and its usage is the same as usual.

[0053] Understandably, this device is used for soil improvement in agricultural production and is suitable for various planting scenarios such as fields, orchards, and vegetable gardens. The distribution mechanism ensures the uniform application of soil conditioner, while the rotary tillage mechanism mixes the conditioner deeply with the soil, simultaneously breaking up compacted soil and leveling the surface. This effectively improves soil structure and fertility, providing a favorable soil environment for crop growth. The equipment is tractor-driven, offering high operational efficiency and suitability for large-scale agricultural production. Furthermore, the bidirectional distribution and uniform rotary tillage design ensures consistent soil improvement, reduces manual labor intensity, and makes it widely applicable for improving soil conditions such as infertility and compaction.

[0054] The specific usage and function of this embodiment are as follows:

[0055] Before use, select the appropriate amendment based on the soil test results. Load the granular or powdered amendment into the distribution hopper 12, ensuring that the amendment covers the bottom of the distribution hopper 12 to avoid uneven initial feeding.

[0056] Connect the equipment to the tractor via the standard three-point suspension mechanism 15 at one end of the frame 11, and check the tightness of the connection rod and rotary tillage mechanism. Adjust the overall height of the equipment and set the rotary tillage depth according to the operation requirements via the tractor; adjust the downward pressing angle of the pressure plate 25 at the end of the machine housing 21 to ensure that the ground surface is flat after rotary tillage.

[0057] Confirm that the wiring of the first drive motor 13, the second drive motor 19, and the third drive motor 26 is normal, and that the protective shell 27 and the protective cover 23 are installed in place to prevent debris from being drawn into the transmission mechanism during operation.

[0058] The tractor is started and the traction equipment moves at a constant speed. Simultaneously, the three sets of drive motors are turned on: the first drive motor 13 drives the double spiral conveyor shaft 14 in the distribution hopper 12 to evenly convey the amendment to the storage box 16; the second drive motor 19 drives the single spiral conveyor shaft 18 in the bidirectional distribution pipe 17 to rotate in the opposite direction, conveying the amendment to both ends of the pipe and evenly spreading it onto the soil surface through multiple sets of discharge ports with gradually changing diameters; the third drive motor 26 drives the central shaft 22 to rotate at high speed through gear and chain transmission, driving the rotary tiller blades 24 and the deep tillage shovel 28 to work.

[0059] During operation, the deep tillage shovel 28 at one end of the protective shell 27 first breaks up the deep, compacted soil. Then, multiple sets of wear-resistant rotary tillage blades 24 break up the soil and simultaneously turn the soil amendment into the deeper layers, achieving mixing between the amendment and the soil. The amendment compensates for the pressure difference through the gradually changing outlet of the bidirectional distribution pipe 17, ensuring consistent feed amount in all areas of the field. After rotary tillage, the soil is compacted and leveled by the compaction plate 25, reducing nutrient volatilization and water loss.

[0060] After the improvement of a plot of land is completed, first turn off the three drive motors, and then stop the tractor from pulling. Clean the residual amendment in the feed hopper 12 and the bidirectional feed pipe 17, check the wear of the rotary tiller blades 24 and the deep tillage shovel 28, and grind or replace them if necessary to ensure the effect of the next operation.

[0061] By selecting three types of specialized soil conditioners, problems such as soil infertility, compaction, pH imbalance, and continuous cropping obstacles can be improved, enhancing soil fertility, aeration, and water and fertilizer retention capacity, thus creating a high-quality soil environment for crop growth.

[0062] The equipment integrates functions such as material distribution, feeding, rotary tillage, and leveling. It can achieve integrated operation by tractor towing, eliminating the need for manual feeding and rotary tillage, greatly reducing labor intensity, and is suitable for the soil improvement needs of large-scale fields, orchards, and vegetable gardens.

[0063] The gradual discharge port setting of the double helix conveyor shaft 14 and the bidirectional material distribution pipe 17 ensures that the amendment is evenly applied; the coordinated operation of the rotary tiller blade 24 and the deep tillage shovel 28 realizes the mixing of the amendment with the deep soil, avoids the waste caused by the amendment floating on the surface, and improves the durability of the amendment effect.

[0064] The standard three-point suspension mechanism 15 can be connected to various types of tractors. The three motors are powerful, energy-efficient, and dust-resistant, making them suitable for agricultural outdoor operation environments. The conditioner has good flowability, is not easy to clog the equipment, and is easy to maintain.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
