Description

Technical Field

[0001] This invention relates to the field of grape cultivation technology, and more specifically, to an agricultural soil improvement device for grape cultivation. Background Technology

[0002] Both before and after planting grapes, soil conditions need to be improved to create a suitable environment for grape growth. Pre-planting improvement methods include tilling, soil replacement, and fertilization, while post-planting methods include weeding, tilling, and fertilization.

[0003] There are two methods for tilling and fertilizing before planting. One is to till all the land and then fertilize before installing the greenhouse. The other is to till or replace the soil in the areas where grapes will be planted after the greenhouse is installed. After the greenhouse is installed, large machinery cannot enter the greenhouse. Tilling equipment can only till the areas in the greenhouse aisles. The areas where grapes will be planted will be obstructed by support poles and cannot be tilled, so tilling or soil replacement can only be done manually. The overall work efficiency is very low. Moreover, the fertilization process requires mixing fertilizer with some soil, which needs to be done in dug pits, resulting in poor mixing. Summary of the Invention

[0004] This invention proposes an agricultural soil improvement device for grape cultivation, which solves the problem of difficult tilling after the greenhouse is installed in related technologies.

[0005] The technical solution of the present invention is as follows: An agricultural soil improvement device for grape cultivation, for mounting on a traction device and tilling the land, comprising: The cover has a connecting part, which is connected to the traction device; A rotary drilling component, comprising several units, is arranged at intervals on the cover body. The rotary drilling component is rotatably mounted on the cover body and located below the cover body. A first transmission component is disposed on the cover, and the first transmission component is used to drive the rotary drilling component to rotate.

[0006] Optional, also includes: A hopper is installed on the cover and located above the cover; the hopper is used to hold fertilizer. The rotary drilling component includes: A rotating shaft is rotatably mounted on the cover. The rotating shaft has a hollow structure and is connected to the hopper. The spiral blades are spirally mounted on the rotating shaft.

[0007] Optional, also includes: An auger is installed inside the rotating shaft and is used to transport fertilizer to the bottom of the rotating shaft.

[0008] Optionally, the auger lifting mechanism is disposed within the rotating shaft, and further includes: A plurality of stirring rods are rotatably mounted at the bottom of the auger, and the stirring rods are parallel to or at an angle to the axis of the auger after rotation.

[0009] Optional, also includes: A transmission box is installed in the hopper, and several of the screw conveyors are connected to the transmission box for transmission. The second transmission component is mounted on the transmission box, and the second transmission component drives the auger to rotate through the transmission box.

[0010] Optionally, the length of the stirring rod is less than or equal to the radius of the helical blade.

[0011] Optional, also includes: A reset element is connected at both ends to the stirring rod and the auger, respectively. The reset element is used to provide a force for one end of the stirring rod to rotate away from the auger.

[0012] Optionally, the hopper has a feed inlet and further includes: The hopper cover is rotated on the hopper, and after the hopper cover is rotated, the feed inlet is closed.

[0013] Optional, also includes: A plurality of retaining plates are provided on the cover, the retaining plates and the cover forming a retaining space, and the rotary drilling component penetrates the retaining space.

[0014] Optionally, the auger has a vent and an outlet.

[0015] The working principle and beneficial effects of this invention are as follows: The soil improvement equipment mainly consists of a cover, a rotary tiller, and a first transmission component. The cover is connected to a traction device via a connecting part. This traction device is a common traction head, especially one suitable for greenhouse cultivation. Furthermore, the size of the cover can be adjusted according to the specific dimensions of the greenhouse. The connecting part uses a connection structure commonly used in existing technology. After the traction device moves the cover to the location where grapes need to be planted, the first transmission component also becomes connected to the traction device. The traction device drives the rotary tiller to rotate through the first transmission component. When the rotary tiller performs rotary tillage, the soil is turned upwards, thus achieving the purpose of tillage.

[0016] This soil improvement equipment enables efficient tilling of grape-growing areas already equipped with greenhouses. Mechanical tilling significantly improves efficiency, reduces manual labor, and produces looser, more suitable soil for grape cultivation. This equipment provides strong support for grape growing, contributing to increased yield and quality. Furthermore, its adjustable canopy design allows it to adapt to greenhouse environments of varying sizes, enhancing its versatility and practicality. In practical applications, equipment parameters can be flexibly selected and adjusted according to specific planting needs and site conditions to achieve optimal soil improvement results.

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-2 , Figure 4-6 The invention relates to an agricultural soil improvement device for grape cultivation, which is installed on a traction device and used to till the land. The device includes: a cover 1 with a connecting part connected to the traction device; a plurality of rotary excavators 2 arranged at intervals on the cover 1, the rotary excavators 2 being rotatably mounted on the cover 1 and located below the cover 1; and a first transmission member 3 mounted on the cover 1 for driving the rotary excavators 2 to rotate.

[0024] In this embodiment, the soil improvement equipment mainly consists of a cover 1, a rotary tiller 2, and a first transmission component 3. The cover 1 is connected to a traction device via a connecting part. This traction device is a common traction head, especially one suitable for greenhouse cultivation. Furthermore, the dimensions of the cover 1 can be adjusted according to the specific dimensions of the greenhouse. The connecting part adopts a connection structure commonly used in the prior art. When the traction device moves the cover 1 to the location where grapes need to be planted, the first transmission component 3 also achieves a transmission connection with the traction device. The traction device drives the rotary tiller 2 to rotate via the first transmission component 3. When the rotary tiller 2 performs rotary tillage, the soil is turned upwards, thereby achieving the purpose of tillage.

[0025] This soil improvement equipment enables efficient tillage of grape-growing areas already equipped with greenhouses. Mechanical tillage significantly improves efficiency, reduces manual labor, and produces looser, more suitable soil for grape cultivation. This equipment provides strong support for grape cultivation, contributing to increased yield and quality. Furthermore, its adjustable-size housing design allows it to better adapt to greenhouse environments of varying sizes, enhancing its versatility and practicality. In practical applications, equipment parameters can be flexibly selected and adjusted according to specific planting needs and site conditions to achieve optimal soil improvement results.

[0026] Optionally, it also includes: a hopper 4 is disposed on the cover 1 and located above the cover 1, and the hopper 4 is used to hold fertilizer; the rotary drilling component 2 includes: a rotating shaft 201 is rotatably disposed on the cover 1, the rotating shaft 201 is a hollow structure, the rotating shaft 201 is connected to the hopper 4; and a spiral blade 202 is spirally disposed on the rotating shaft 201.

[0027] In this embodiment, to better achieve soil improvement, soil replacement and fertilization are carried out simultaneously with tilling. The rotary excavator 2 effectively turns the soil upwards during rotation. When the rotary excavator 2 reaches a specific depth, fertilizer is added to the hopper 4. The fertilizer smoothly enters the ground through the rotating shaft 201. At this time, the rotary excavator 2 continues to rotate, constantly turning the soil at the bottom upwards, thus making space for the fertilizer. The fertilizer that enters first is fully mixed with the soil under the action of the rotary excavator 2 and moves upwards, reserving space for the fertilizer that enters later. Simultaneously, some soil will sink under gravity and mix again with the fertilizer that enters later. This cycle repeats, allowing fertilizer to be directly injected into the ground and fully mixed with some of the soil. The fertilizer will occupy part of the original soil space, while excess soil will accumulate under the cover 1. Compared with the traditional manual excavation method, this embodiment does not require digging out all the soil before filling in the fertilizer; instead, the fertilizer is directly injected into the ground, and the injection operation can be completed simultaneously with tilling. In addition, mechanical mixing is significantly more effective than manual mixing, enabling soil and fertilizer to combine more evenly and providing a more efficient and higher-quality solution for soil improvement.

[0028] Furthermore, another operating procedure exists. After the rotary drilling rig 2 digs to a specific depth, it rises to the maximum height required for fertilizer application, and then fertilizer is added. Simultaneously, the rotary drilling rig 2 gradually descends, allowing fertilizer to be discharged at different heights. This method results in a more even distribution of fertilizer in the soil and better mixing. At the same time, this operating process fully demonstrates the flexibility and efficiency of the soil improvement equipment, enabling precise fertilizer application and mixing according to actual needs, thus improving the quality and effectiveness of soil improvement.

[0029] Optionally, it also includes: an auger 501 disposed inside the rotating shaft 201, the auger 501 being used to transport fertilizer to the bottom of the rotating shaft 201.

[0030] In this embodiment, an auger 501 is installed in the rotating shaft 201 to facilitate better penetration of the fertilizer into the soil. When the fertilizer enters the rotating shaft 201 from the hopper 4, the auger 501 begins to operate. The rotational motion of the auger 501 generates a certain propulsive force, conveying the fertilizer forward along the rotating shaft 201. Since the auger 501 can provide a certain pressure conveying effect, this is equivalent to using pressure to force the fertilizer into the soil. This pressure conveying method overcomes the resistance of the soil to the fertilizer, ensuring that the fertilizer can smoothly penetrate to different depths in the soil.

[0031] In actual operation, while the rotary excavator 2 is rotating and tilling the soil, the auger 501 continuously delivers fertilizer underground. The pressure delivery of the auger 501 not only prevents soil from clogging the shaft 201, but also allows the fertilizer to be distributed more evenly in the soil. Without the pressure delivery of the auger 501, the fertilizer may accumulate at the inlet of the shaft 201 due to soil resistance, or it may not be able to penetrate to deeper layers of the soil, thus affecting the soil improvement effect.

[0032] Furthermore, the rotation speed of the auger 501 can be adjusted according to actual conditions. If the soil is relatively loose and the resistance is low, the rotation speed of the auger 501 can be appropriately reduced to save energy; if the soil is relatively compact and the resistance is high, the rotation speed of the auger 501 can be increased to ensure that the fertilizer can be transported smoothly. At the same time, the conveying pressure and speed of the auger 501 can be adjusted according to different types of fertilizers to adapt to the characteristics of different fertilizers and the needs of soil improvement. The auger 501 also prevents soil from entering the rotating shaft 201, preventing the shaft from becoming clogged.

[0033] In summary, the installation of the auger 501 in the rotating shaft 201 can improve the efficiency and uniformity of fertilizer entering the soil, prevent soil from clogging the rotating shaft 201, provide a strong guarantee for soil improvement, and allow excess fertilizer to be loaded first, with the auger 501 controlling the amount of fertilizer discharged.

[0034] like Figure 3 and Figure 7 As shown, the auger 501 is raised and lowered inside the rotating shaft 201, and also includes: several stirring rods 502, which are rotatably disposed at the bottom of the auger 501. After the stirring rods 502 rotate, they are parallel to the axis of the auger 501 or have an angle with it.

[0035] In this embodiment, a stirring rod 502 is installed at the bottom of the auger 501 to achieve better mixing of soil and fertilizer. This design takes into account several key aspects of the soil improvement process, aiming to improve the uniformity of fertilizer and soil mixing and create more ideal soil conditions for plant growth.

[0036] When the rotary drilling component 2 is not in operation, the mixing rod 502 is cleverly housed inside the rotating shaft 201. This design ensures the compactness of the equipment when not in operation and avoids potential external damage to the mixing rod 502. At the same time, the position of the mixing rod 502 inside the rotating shaft 201 does not interfere with the overall structure and spatial layout of the equipment, making the equipment more convenient to store and transport.

[0037] When fertilizer needs to be fed, the auger 501 rotates and descends at a specific speed. As the auger 501 descends, after the stirring rod 502 leaves the rotating shaft 201, the stirring rod 502 can automatically open under the rotation of the auger 501. The opening angle and speed of the stirring rod 502 can be adjusted according to actual needs to adapt to different types of fertilizers and soil conditions.

[0038] At this point, the fertilizer falls from the rotating shaft 201. The stirring rod 502 immediately breaks up the falling fertilizer. After being broken up, the fertilizer particles are more uniform in size, increasing the contact area between the fertilizer and the soil. This not only helps improve the utilization rate of the fertilizer, but also allows the fertilizer to dissolve and release nutrients in the soil more quickly.

[0039] While the fertilizer is being broken down, the mixing rod 502 also mixes some of the soil with the fertilizer. The rotation and mixing action of the mixing rod 502 ensures thorough contact between the soil and fertilizer, promoting the even distribution of the fertilizer in the soil. Furthermore, the rotation speed of the mixing rod 502 can be adjusted according to the soil properties and the type of fertilizer to achieve the best mixing effect.

[0040] For example, for looser soil, the mixing rod 502 can rotate at a faster speed to ensure that the fertilizer is quickly mixed with the soil; while for more compacted soil, the rotation speed of the mixing rod 502 can be appropriately reduced to avoid over-mixing and damage to the structure of the mixing rod 502. In addition, the mixing rod 502 can also be adjusted according to the characteristics of the fertilizer.

[0041] By incorporating a mixing rod 502 at the bottom of the auger 501, fertilizer can be effectively broken down, and the mixing of soil and fertilizer can be promoted, thus improving the soil improvement effect. In practical applications, this design can be flexibly adjusted and optimized according to different soil types, fertilizer types, and planting needs.

[0042] like Figures 1-7As shown, it also includes: a transmission box 6 is lifted and installed inside the hopper 4, and several augers 501 are connected to the transmission box 6 for transmission; a second transmission component 7 is installed on the transmission box 6, and the second transmission component 7 drives the augers 501 to rotate through the transmission box 6.

[0043] In this embodiment, to enable multiple augers 501 to use a single drive, the augers 501 are connected to the transmission box 6 via a transmission connection. The second transmission component 7 is also connected to the transmission box 6 via a transmission connection, and preferably, gear transmission can be used inside the transmission box 6. Gear transmission has advantages such as high transmission efficiency, accurate transmission ratio, and compact structure, and can effectively transmit power from one component to another.

[0044] The second transmission component 7 is connected to the traction device, and the traction device drives the second transmission component 7 to move. The traction device, as a power source, provides power to the entire system. When the traction device is working, it drives the second transmission component 7 to move, and the second transmission component 7 then transmits the power to the transmission box 6. The gear transmission system inside the transmission box 6 distributes the power to each auger 501, enabling multiple augers 501 to work simultaneously.

[0045] This design not only saves energy but also reduces equipment complexity and cost. Driving multiple augers 501 with a single traction device improves equipment efficiency and reduces maintenance and operational difficulties. Simultaneously, the reliability and stability of the gear transmission ensure long-term equipment operation.

[0046] In practical applications, the gear ratio of the transmission box 6 can be adjusted according to specific needs and working conditions to meet different speed and torque requirements of the auger 501. Furthermore, the power and speed of the traction device can be controlled to achieve precise adjustment of the auger 501's operating state.

[0047] Optionally, the length of the stirring rod 502 is less than or equal to the radius of the spiral blade 202.

[0048] In this embodiment, to better utilize the function of the stirring rod 502, and considering the possibility of multiple sets of stirring rods 502 being provided, a special optimization design was implemented. To prevent interference between the stirring rods 502, the length of the stirring rod 502 is set to be less than the radius of the helical blade 202.

[0049] First, when the mixing rod 502 is deployed in the working state, because its length is less than the radius of the spiral blade 202, even when the mixing rod 502 is deployed to its maximum extent, it will not exceed the range of the rotary drilling component 2. This effectively avoids possible collisions between the mixing rod 502 and the rotary drilling component 2, ensuring the safety and stability of the equipment during operation.

[0050] Secondly, this design also ensures that the mixing rod 502 can move more flexibly during operation. Since it will not exceed the range of the rotary excavator 2, the mixing rod 502 can more precisely control its movement trajectory during the process of crushing fertilizer and mixing it with soil, thereby improving the efficiency and uniformity of mixing.

[0051] Furthermore, the length limitation of the multiple mixing rods 502 ensures that a certain distance is maintained between each rod, preventing mutual interference and tangling. Each mixing rod 502 can function independently, thus achieving better mixing of soil and fertilizer.

[0052] Optionally, it also includes: a reset member, with its two ends connected to the stirring rod 502 and the auger 501 respectively, the reset member being used to provide a force that rotates one end of the stirring rod 502 away from the auger 501.

[0053] In this embodiment, to ensure that the stirring rod 502 can unfold better after leaving the rotating shaft 201, a reset member is provided between the stirring rod 502 and the auger 501. When the stirring rod 502 leaves the rotating shaft 201 as the auger 501 descends, the reset member begins to function. The reset member can generate a certain force, causing the stirring rod 502 to unfold. This design ensures that the stirring rod 502 can quickly and accurately unfold to the predetermined position when needed, preparing for the crushing of fertilizer and mixing with the soil.

[0054] The specific form of the reset element can vary, such as springs and torsion springs. These reset elements have different characteristics and advantages, and can be selected according to the actual situation. For example, springs have advantages such as good elasticity and low cost, while torsion springs can provide greater torque and are suitable for situations requiring greater unfolding force.

[0055] By incorporating a reset mechanism, not only can the reliability and stability of the stirring rod 502's deployment be improved, but the operation of the equipment can also be made simpler and more efficient. In practical applications, operators only need to control the auger 501 to lower it, allowing the stirring rod 502 to deploy automatically without additional operation, greatly improving work efficiency.

[0056] Optionally, the hopper 4 has a feed inlet and also includes: a hopper cover 401 that rotates on the hopper 4, and the feed inlet is closed after the hopper cover 401 rotates.

[0057] In this embodiment, a cover 401 is provided on the top of the hopper 4. After fertilizer is loaded into the hopper 4, the cover 401 should be closed promptly to effectively prevent fertilizer spillage. During equipment operation, various situations may occur, such as vibration and tilting. Without the cover 401, fertilizer could easily spill out of the hopper 4, causing waste and potential environmental pollution. With the protection of the cover 401, the fertilizer is firmly sealed inside the hopper 4, ensuring that it will not spill regardless of equipment movement.

[0058] Meanwhile, the design of the silo cover 401 also improves the overall safety of the equipment. During equipment operation, the silo cover 401 can prevent operators or other personnel from accidentally coming into contact with the fertilizer inside the silo 4, thus avoiding accidents.

[0059] Optionally, it also includes: a plurality of retaining plates 101 are provided on the cover 1, the retaining plates 101 and the cover 1 form a retaining space, and the rotary drilling component 2 penetrates through the retaining space.

[0060] In this embodiment, in order to prevent excess soil from scattering or splashing, a soil retaining plate 101 is set on the cover 1 to form a soil retaining space with the cover 1. Excess soil enters the soil retaining space and can be collected and cleaned manually.

[0061] Optionally, the screw conveyor 501 has a vent 503 and an air outlet 504.

[0062] In this embodiment, to achieve better soil looseness, air is blown into the fertilizer and soil during fertilization. Firstly, blowing air increases soil looseness. The injection of gas increases the gaps between soil particles, making the soil more porous. This loose soil structure is beneficial for plant root growth and respiration, enabling better absorption of water and nutrients.

[0063] Secondly, air blowing promotes the mixing of fertilizer with the soil. The flow of gas helps fertilizer particles diffuse throughout the soil, distributing them more evenly. This increases the contact area between the fertilizer and the soil, improving fertilizer utilization.

[0064] In addition, aeration can improve soil permeability. Adequate oxygen supply is crucial for the activity of soil microorganisms. Good aeration promotes microbial reproduction and metabolism, accelerates the decomposition and transformation of organic matter in the soil, and further enhances soil fertility.

[0065] To achieve the aeration function, an aeration device can be installed on the traction device, which is connected to the ventilation channel 503 of the auger 501. This device can work in conjunction with the fertilization system, adjusting the aeration intensity and frequency as needed. For example, different aeration parameters can be selected based on the soil type and compaction to achieve the optimal loosening effect. Figure 1-2 , Figure 4-6 The invention relates to an agricultural soil improvement device for grape cultivation, which is installed on a traction device and used to till the land. The device includes: a cover 1 with a connecting part connected to the traction device; a plurality of rotary excavators 2 arranged at intervals on the cover 1, the rotary excavators 2 being rotatably mounted on the cover 1 and located below the cover 1; and a first transmission member 3 mounted on the cover 1 for driving the rotary excavators 2 to rotate.

[0066] In this embodiment, the soil improvement equipment mainly consists of a cover 1, a rotary tiller 2, and a first transmission component 3. The cover 1 is connected to a traction device via a connecting part. This traction device is a common traction head, especially one suitable for greenhouse cultivation. Furthermore, the dimensions of the cover 1 can be adjusted according to the specific dimensions of the greenhouse. The connecting part adopts a connection structure commonly used in the prior art. When the traction device moves the cover 1 to the location where grapes need to be planted, the first transmission component 3 also achieves a transmission connection with the traction device. The traction device drives the rotary tiller 2 to rotate via the first transmission component 3. When the rotary tiller 2 performs rotary tillage, the soil is turned upwards, thereby achieving the purpose of tillage.

[0067] This soil improvement equipment enables efficient tillage of grape-growing areas already equipped with greenhouses. Mechanical tillage significantly improves efficiency, reduces manual labor, and produces looser, more suitable soil for grape cultivation. This equipment provides strong support for grape cultivation, contributing to increased yield and quality. Furthermore, its adjustable-size housing design allows it to better adapt to greenhouse environments of varying sizes, enhancing its versatility and practicality. In practical applications, equipment parameters can be flexibly selected and adjusted according to specific planting needs and site conditions to achieve optimal soil improvement results.

[0068] Optionally, it also includes: a hopper 4 is disposed on the cover 1 and located above the cover 1, and the hopper 4 is used to hold fertilizer; the rotary drilling component 2 includes: a rotating shaft 201 is rotatably disposed on the cover 1, the rotating shaft 201 is a hollow structure, the rotating shaft 201 is connected to the hopper 4; and a spiral blade 202 is spirally disposed on the rotating shaft 201.

At the same time, this operating process fully demonstrates the flexibility and efficiency of the soil improvement equipment, enabling precise fertilizer application and mixing according to actual needs, thus improving the quality and effectiveness of soil improvement.

[0071] Optionally, it also includes: an auger 501 disposed inside the rotating shaft 201, the auger 501 being used to transport fertilizer to the bottom of the rotating shaft 201.

The auger 501 also prevents soil from entering the rotating shaft 201, preventing the shaft from becoming clogged.

[0075] In summary, the installation of the auger 501 in the rotating shaft 201 can improve the efficiency and uniformity of fertilizer entering the soil, prevent soil from clogging the rotating shaft 201, provide a strong guarantee for soil improvement, and allow excess fertilizer to be loaded first, with the auger 501 controlling the amount of fertilizer discharged.

[0076] like Figure 3 and Figure 7 As shown, the auger 501 is raised and lowered inside the rotating shaft 201, and also includes: several stirring rods 502, which are rotatably disposed at the bottom of the auger 501. After the stirring rods 502 rotate, they are parallel to the axis of the auger 501 or have an angle with it.

At the same time, the position of the mixing rod 502 inside the rotating shaft 201 does not interfere with the overall structure and spatial layout of the equipment, making the equipment more convenient to store and transport.

[0079] When fertilizer needs to be fed, the auger 501 rotates and descends at a specific speed. As the auger 501 descends, after the stirring rod 502 leaves the rotating shaft 201, the stirring rod 502 can automatically open under the rotation of the auger 501. The opening angle and speed of the stirring rod 502 can be adjusted according to actual needs to adapt to different types of fertilizers and soil conditions.

[0080] At this point, the fertilizer falls from the rotating shaft 201. The stirring rod 502 immediately breaks up the falling fertilizer. After being broken up, the fertilizer particles are more uniform in size, increasing the contact area between the fertilizer and the soil. This not only helps improve the utilization rate of the fertilizer, but also allows the fertilizer to dissolve and release nutrients in the soil more quickly.

[0081] While the fertilizer is being broken down, the mixing rod 502 also mixes some of the soil with the fertilizer. The rotation and mixing action of the mixing rod 502 ensures thorough contact between the soil and fertilizer, promoting the even distribution of the fertilizer in the soil. Furthermore, the rotation speed of the mixing rod 502 can be adjusted according to the soil properties and the type of fertilizer to achieve the best mixing effect.

[0082] For example, for looser soil, the mixing rod 502 can rotate at a faster speed to ensure that the fertilizer is quickly mixed with the soil; while for more compacted soil, the rotation speed of the mixing rod 502 can be appropriately reduced to avoid over-mixing and damage to the structure of the mixing rod 502. In addition, the mixing rod 502 can also be adjusted according to the characteristics of the fertilizer.

[0083] By incorporating a mixing rod 502 at the bottom of the auger 501, fertilizer can be effectively broken down, and the mixing of soil and fertilizer can be promoted, thus improving the soil improvement effect. In practical applications, this design can be flexibly adjusted and optimized according to different soil types, fertilizer types, and planting needs.

[0084] like Figures 1-7 As shown, it also includes: a transmission box 6 is lifted and installed inside the hopper 4, and several augers 501 are connected to the transmission box 6 for transmission; a second transmission component 7 is installed on the transmission box 6, and the second transmission component 7 drives the augers 501 to rotate through the transmission box 6.

[0085] In this embodiment, to enable multiple augers 501 to use a single drive, the augers 501 are connected to the transmission box 6 via a transmission connection. The second transmission component 7 is also connected to the transmission box 6 via a transmission connection, and preferably, gear transmission can be used inside the transmission box 6. Gear transmission has advantages such as high transmission efficiency, accurate transmission ratio, and compact structure, and can effectively transmit power from one component to another.

[0086] The second transmission component 7 is connected to the traction device, and the traction device drives the second transmission component 7 to move. The traction device, as a power source, provides power to the entire system. When the traction device is working, it drives the second transmission component 7 to move, and the second transmission component 7 then transmits the power to the transmission box 6. The gear transmission system inside the transmission box 6 distributes the power to each auger 501, enabling multiple augers 501 to work simultaneously.

[0087] This design not only saves energy but also reduces equipment complexity and cost. Driving multiple augers 501 with a single traction device improves equipment efficiency and reduces maintenance and operational difficulties. Simultaneously, the reliability and stability of the gear transmission ensure long-term equipment operation.

[0088] In practical applications, the gear ratio of the transmission box 6 can be adjusted according to specific needs and working conditions to meet different speed and torque requirements of the auger 501. Furthermore, the power and speed of the traction device can be controlled to achieve precise adjustment of the auger 501's operating state.

[0089] Optionally, the length of the stirring rod 502 is less than or equal to the radius of the spiral blade 202.

[0090] In this embodiment, to better utilize the function of the stirring rod 502, and considering the possibility of multiple sets of stirring rods 502 being provided, a special optimization design was implemented. To prevent interference between the stirring rods 502, the length of the stirring rod 502 is set to be less than the radius of the helical blade 202.

[0091] First, when the mixing rod 502 is deployed in the working state, because its length is less than the radius of the spiral blade 202, even when the mixing rod 502 is deployed to its maximum extent, it will not exceed the range of the rotary drilling component 2. This effectively avoids possible collisions between the mixing rod 502 and the rotary drilling component 2, ensuring the safety and stability of the equipment during operation.

[0092] Secondly, this design also ensures that the mixing rod 502 can move more flexibly during operation. Since it will not exceed the range of the rotary excavator 2, the mixing rod 502 can more precisely control its movement trajectory during the process of crushing fertilizer and mixing it with soil, thereby improving the efficiency and uniformity of mixing.

[0093] Furthermore, the length limitation of the multiple mixing rods 502 ensures that a certain distance is maintained between each rod, preventing mutual interference and tangling. Each mixing rod 502 can function independently, thus achieving better mixing of soil and fertilizer.

[0094] Optionally, it also includes: a reset member, with its two ends connected to the stirring rod 502 and the auger 501 respectively, the reset member being used to provide a force that rotates one end of the stirring rod 502 away from the auger 501.

[0095] In this embodiment, to ensure that the stirring rod 502 can unfold better after leaving the rotating shaft 201, a reset member is provided between the stirring rod 502 and the auger 501. When the stirring rod 502 leaves the rotating shaft 201 as the auger 501 descends, the reset member begins to function. The reset member can generate a certain force, causing the stirring rod 502 to unfold. This design ensures that the stirring rod 502 can quickly and accurately unfold to the predetermined position when needed, preparing for the crushing of fertilizer and mixing with the soil.

[0096] The specific form of the reset element can vary, such as springs and torsion springs. These reset elements have different characteristics and advantages, and can be selected according to the actual situation. For example, springs have advantages such as good elasticity and low cost, while torsion springs can provide greater torque and are suitable for situations requiring greater unfolding force.

[0097] By incorporating a reset mechanism, not only can the reliability and stability of the stirring rod 502's deployment be improved, but the operation of the equipment can also be made simpler and more efficient. In practical applications, operators only need to control the auger 501 to lower it, allowing the stirring rod 502 to deploy automatically without additional operation, greatly improving work efficiency.

[0098] Optionally, the hopper 4 has a feed inlet and also includes: a hopper cover 401 that rotates on the hopper 4, and the feed inlet is closed after the hopper cover 401 rotates.

[0099] In this embodiment, a cover 401 is provided on the top of the hopper 4. After fertilizer is loaded into the hopper 4, the cover 401 should be closed promptly to effectively prevent fertilizer spillage. During equipment operation, various situations may occur, such as vibration and tilting. Without the cover 401, fertilizer could easily spill out of the hopper 4, causing waste and potential environmental pollution. With the protection of the cover 401, the fertilizer is firmly sealed inside the hopper 4, ensuring that it will not spill regardless of equipment movement.

[0100] Meanwhile, the design of the silo cover 401 also improves the overall safety of the equipment. During equipment operation, the silo cover 401 can prevent operators or other personnel from accidentally coming into contact with the fertilizer inside the silo 4, thus avoiding accidents.

[0101] Optionally, it also includes: a plurality of retaining plates 101 are provided on the cover 1, the retaining plates 101 and the cover 1 form a retaining space, and the rotary drilling component 2 penetrates through the retaining space.

[0102] In this embodiment, in order to prevent excess soil from scattering or splashing, a soil retaining plate 101 is set on the cover 1 to form a soil retaining space with the cover 1. Excess soil enters the soil retaining space and can be collected and cleaned manually.

[0103] Optionally, the screw conveyor 501 has a vent 503 and an air outlet 504.

[0104] In this embodiment, to achieve better soil looseness, air is blown into the fertilizer and soil during fertilization. Firstly, blowing air increases soil looseness. The injection of gas increases the gaps between soil particles, making the soil more porous. This loose soil structure is beneficial for plant root growth and respiration, enabling better absorption of water and nutrients.

[0105] Secondly, air blowing promotes the mixing of fertilizer with the soil. The flow of gas helps fertilizer particles diffuse throughout the soil, distributing them more evenly. This increases the contact area between the fertilizer and the soil, improving fertilizer utilization.

[0106] In addition, aeration can improve soil permeability. Adequate oxygen supply is crucial for the activity of soil microorganisms. Good aeration promotes microbial reproduction and metabolism, accelerates the decomposition and transformation of organic matter in the soil, and further enhances soil fertility.

[0107] To achieve the aeration function, an aeration device can be installed on the traction device, which is connected to the ventilation channel 503 of the auger 501. This device can work in conjunction with the fertilization system, adjusting the intensity and frequency of aeration as needed. For example, different aeration parameters can be selected based on the soil type and compaction to achieve the best loosening effect.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
