[0039] See also Figure 1-Figure 3 .

[0040] Some embodiments of the present application disclose a mixed fertilization tillage machine, comprising a frame 1, a fertilizer box 2, an organic fertilizer box 3 and a mixing box 4, wherein the frame 1 is used to install the fertilizer box 2, the organic fertilizer box 3 and the mixing box 4, the fertilizer box 2 is used to hold fertilizer, the organic fertilizer box 3 is used to hold organic fertilizer, the fertilizer box 2 and the organic fertilizer box 3 are both connected to the mixing box 4, and the mixing box 4 is used to hold a mixture of fertilizer and organic fertilizer.

[0041] After mixing, the chemical fertilizer and the organic fertilizer are discharged through the discharge pipe 42 of the mixing box 4 to the cultivated land. Optionally, a stirrer 41 is provided in the mixing box 4 to stir the chemical fertilizer and the organic fertilizer in the mixing box 4 so that the chemical fertilizer and the organic fertilizer are evenly mixed.

[0042] The agitator 41 can be a second auger or a stirring paddle. In the embodiment where the agitator 41 is a second auger, one end of the second auger is connected to the organic fertilizer tank 3, and the other end of the second auger is connected to the mixing tank 4. The second auger can break up the organic fertilizer while transporting it, which not only helps to mix the organic fertilizer with the chemical fertilizer, but also reduces the risk of blocking the feed pipe 42.

[0043] The mixed fertilizer tilling machine disclosed in the present scheme also includes a regulating component for adjusting the ratio of chemical fertilizer and organic fertilizer. In some embodiments, the regulating component includes a sensor 11, a fertilizer flow controller 5, an organic fertilizer flow controller 6 and a main controller 12, wherein the sensor 11 is used to detect soil conditions, wherein the soil conditions include the content of nitrogen, phosphorus, potassium, pH value and water in the soil; the fertilizer flow controller 5 is installed on the fertilizer box 2, and is used to adjust the flow rate of chemical fertilizer discharged from the fertilizer box 2; the organic fertilizer flow controller 6 is installed on the organic fertilizer box 3, and is used to adjust the flow rate of organic fertilizer discharged from the organic fertilizer box 3; the main controller 12 is connected in communication with the sensor 11, the fertilizer flow controller 5 and the organic fertilizer flow controller 6, and the main controller 12 is used to set the ratio and fertilizer amount of chemical fertilizer and organic fertilizer according to the crop type and the soil conditions collected by the sensor 11, and control the fertilizer flow sensor to adjust the flow rate of chemical fertilizer according to the ratio, and control the organic fertilizer flow sensor to adjust the flow rate of organic fertilizer, so that the fertilizer box 2 and the organic fertilizer box 3 supply chemical fertilizer and organic fertilizer to the mixing box 4 respectively according to the set ratio.

[0044] The mixed fertilizer tillage machine disclosed in this scheme can adjust the ratio of chemical fertilizers and organic fertilizers according to crop types and soil conditions, achieve precise fertilization, ensure that crops obtain a balanced nutrient supply, and improve crop yield and quality. At the same time, it can also ensure that chemical fertilizers and organic fertilizers are used efficiently and avoid excessive or uneven fertilization.

[0045] The mixed fertilizer tillage machine disclosed in this scheme sets the ratio of chemical fertilizer and organic fertilizer and the amount of fertilizer according to the crop type and soil conditions, realizes scientific fertilization and rational use of organic fertilizer, protects soil materials, maintains ecological balance, promotes the sustainable development of agriculture, and brings more lasting economic benefits.

[0046] Optionally, the main controller 12 pre-stores the ratio of chemical fertilizers and organic fertilizers, as well as the amount of chemical fertilizers and organic fertilizers applied, which are set according to different crop types and soil conditions. The main controller 12 automatically outputs the set ratio of chemical fertilizers and organic fertilizers, as well as the amount of chemical fertilizers and organic fertilizers applied, according to the crop type set by the operator and the soil conditions collected in real time by the sensor 11, and then controls the chemical fertilizer flow controller 5 to adjust the flow rate (or fertilizer output) of the chemical fertilizer, and controls the organic fertilizer flow controller 6 to adjust the flow rate (or fertilizer output) of the organic fertilizer, thereby realizing automated fertilization.

[0047] Optionally, the operator can manually select a suitable ratio of chemical fertilizers and organic fertilizers, as well as the amount of chemical fertilizers and organic fertilizers to be applied, based on the crop type and historical soil conditions collected by the sensor 11, thereby increasing the flexibility of adjusting the ratio of chemical fertilizers and organic fertilizers, as well as the flexibility of adjusting the amount of fertilizers to be applied.

[0048] This solution uses the main controller 12, the sensor 11, the fertilizer flow controller 5 and the organic fertilizer flow controller 6 to apply enough fertilizer at one time, accurately fertilize, avoid time waste and fertilizer waste caused by repeated fertilization, reduce fertilizer waste, save agricultural material costs, and effectively reduce resource waste.

[0049] Excessive fertilization will lead to fertilizer loss and pollute the soil and water sources, while precise fertilization can reduce the loss of nitrogen, phosphorus and other components, reduce pollution to the environment, avoid soil compaction and salinization, and maintain long-term soil fertility and health.

[0050] A flow controller is a machine device used to control flow, usually used in facilities such as pipelines. Its main function is to adjust flow, thereby controlling flow within the required range. A flow controller usually includes sensors, actuators, control circuits, and software, among which the sensor is used to measure the flow of the medium in the pipeline, the actuator is used to control the flow of the medium, the control circuit is used to process the measurement results of the sensor and send the flow control signal to the actuator, and the software is used to implement the algorithm and logic of the flow controller. Automatic control is achieved by setting the target flow, sending a control signal to the flow controller, and the flow controller adjusts the flow according to the set value.

[0051] The mixed fertilizer tillage machine disclosed in the present solution also includes a rotary tillage device 7, which is installed on the frame 1 and is used to chop and turn the soil to enhance the uniformity of mixing the mixed fertilizer and the soil.

[0052] The rotary tillage device 7 has a strong soil crushing ability, and can crush the soil, mix the soil and fertilizer evenly, and level the ground in one operation.

[0053] The rotary tillage device 7 can be arranged upstream of the feed pipe 42, or downstream of the feed pipe 42, or both upstream and downstream of the feed pipe 42. It should be noted that the upstream and downstream refer to the movement direction of the mixed fertilizer tillage machine. The mixed fertilizer tillage machine is connected to a motor vehicle, such as a tractor, and the motor vehicle pulls the mixed fertilizer tillage machine to travel on the cultivated land. The side of the feed pipe 42 in the forward direction is the upstream, and the side of the feed pipe 42 in the opposite direction of the forward direction is the downstream.

[0054] In the embodiment where the rotary tillage device 7 is arranged upstream of the feed pipe 42, the rotary tillage device 7 first chops and turns the soil, and then the mixed fertilizer of chemical fertilizer and organic fertilizer is spread on the cultivated land;

[0055] In the embodiment where the rotary tillage device 7 is arranged downstream of the feed pipe 42, the mixed fertilizer of chemical fertilizer and organic fertilizer is first spread on the cultivated land, and then the rotary tillage device 7 chops and turns the soil with the mixed fertilizer of chemical fertilizer and organic fertilizer to achieve uniform mixing of the mixed fertilizer and the soil;

[0056] In the embodiment where the rotary tillage device 7 is arranged upstream and downstream of the feed pipe 42, the rotary tillage device 7 first chops and turns the soil, and then the mixed fertilizer of chemical fertilizer and organic fertilizer is scattered on the cultivated land. The rotary tillage device 7 then chops and turns the soil with the mixed fertilizer of chemical fertilizer and organic fertilizer to achieve uniform mixing of the mixed fertilizer and the soil. After the cultivated land is turned twice, the uniformity of the mixing of the mixed fertilizer and the soil is improved.

[0057] The mixed fertilizer tillage machine disclosed in the scheme can chop and turn the soil while applying fertilizer, thus realizing two functions at one time and improving the efficiency of tilling land.

[0058] The mixed fertilizer tillage machine disclosed in the present solution also includes a pressing wheel 8, which is installed on the frame 1 and located at the rear of the frame 1 and is used for compacting the cultivated land.

[0059] The function of the pressing wheel 8 is to compact the soil so that the fertilizer is in close contact with the soil, reduce water evaporation, and facilitate the rise of water in the lower layer.

[0060] The mixed fertilization tillage machine disclosed in this scheme has a feed pipe 42, a rotary tillage device 7 and a pressing wheel 8 arranged in sequence along the forward direction of the motor vehicle. The mixed fertilization tillage machine first applies fertilizer through the feed pipe 42, then chops and turns the cultivated land through the rotary tillage device 7 to evenly mix the soil and fertilizer, and finally compacts the fertilizer and soil through the pressing wheel 8.

[0061] The mixed fertilizer tillage machine achieves three operations in one run. Compared with the method of performing each operation separately, it reduces the number of times the machine enters the field and improves the tillage efficiency. It can also avoid repeated fertilization due to operational errors, reduce fertilizer waste, save agricultural inputs costs, and effectively reduce resource waste.

[0062] The mixed fertilizer tillage machine disclosed in this scheme can realize the integrated machineization of mixed fertilizers in a fixed ratio, fertilization, rotary tillage, and compaction, optimize the integrated fertilization and land preparation plan, scientifically guide agricultural production, have a high degree of automation, and improve the working efficiency and flexibility of agricultural machinery; reduce manual operation and reduce labor intensity; combine with modern agricultural information technology to achieve refined management of farmland and improve the scientific and technological content and management level of agricultural production.

[0063] The sensor 11 collects soil conditions in real time and dynamically adjusts fertilization parameters (including the ratio of chemical fertilizers and organic fertilizers, and the amount of fertilizer, etc.) to ensure a balanced nutrient supply.

[0064] The data of each fertilization is recorded to form a historical data table, and the decision model is continuously optimized based on the historical data (for example, based on crop type, soil conditions, etc., stored in the main controller 12) to improve the accuracy and efficiency of fertilization.

[0065] In some embodiments, a first auger 10 is provided at the outlet of the organic fertilizer, and the first auger 10 is used to transport the organic fertilizer to the mixing box 4.

[0066] The first auger 10 can also break up the organic fertilizer to improve the uniformity of the mixture of the organic fertilizer and the chemical fertilizer.

[0067] The first auger 10 is in communication connection with the main controller 12 , and the main controller 12 controls the rotation speed of the first auger 10 . The first auger 10 cooperates with the organic fertilizer flow controller 6 to control the output amount of the organic fertilizer.

[0068] like Figure 2 and Figure 3 As shown, the first auger 10 is installed at the box opening of the mixing box 4.

[0069] The outlet of the fertilizer tank 2 is provided with a pump for pumping the fertilizer in the fertilizer tank 2 to the mixing tank 4 .

[0070] The pump is connected to the main controller 12 for communication. The main controller 12 controls the rotation speed of the pump. The pump cooperates with the fertilizer flow controller 5 to control the output amount of the fertilizer.

[0071] In the embodiment in which a pump is arranged at the outlet of the fertilizer tank 2, the pump provides power for the transportation of the fertilizer in the fertilizer tank 2, so that the setting position of the fertilizer tank 2 is more flexible. It can be arranged not only at the box opening of the mixing box 4, but also outside the mixing box 4. The height can be higher than the box opening of the mixing box 4, and can also be lower than the box opening of the mixing box 4.

[0072] In this solution, the fertilizer box 2 and the organic fertilizer box 3 are both arranged at the box opening of the mixing box 4 and installed on the mixing box 4. The fertilizer and the organic fertilizer can fall under the action of gravity, which on the one hand ensures the reliability of the discharge and on the other hand reduces the external power input.

[0073] The feed pipe 42 includes multiple rows of feed pipe groups, each row of feed pipe groups includes multiple branch pipes arranged along the front-to-back direction of the frame 1 , and the multiple rows of feed pipe groups are arranged along the front-to-back direction perpendicular to the frame 1 .

[0074] The feeding pipe 42 is composed of multiple rows of feeding pipe groups to form multiple feeding points. The multiple feeding points simultaneously feed the arable land. The mixed chemical fertilizer and organic fertilizer are dispersed through the multiple feeding pipe groups to achieve uniform scattering of the mixed fertilizer on the arable land.

[0075] Due to the uneven surface of the cultivated land, the mixed fertilizer tillage machine will inevitably vibrate when running on the cultivated land, and the multi-row feed pipe group will also vibrate with the mixed fertilizer tillage machine, reducing the risk of blockage of the feed pipe 42

[0076] The feed pipe 42 may also be a pipe with a larger diameter, with a screen provided at the pipe opening, through which the mixed fertilizer is scattered on the cultivated land, thereby improving the uniformity of the mixed fertilizer application.

[0077] In this solution, the frame 1 is connected to the motor vehicle through the suspension bracket 9, which provides an installation basis for the connection between the mixed fertilizer tillage machine and the motor vehicle.

[0078] The suspension bracket 9 is welded on the frame 1, and the suspension bracket 9 is hingedly connected to the motor vehicle. Specifically, the suspension bracket 9 includes a V-shaped support plate, the open end of the V-shaped support plate is connected to the frame 1, and the closed end of the V-shaped support plate is provided with a first ear plate. The frame 1 has two side plates corresponding to the V-shaped support plate and have a second ear plate. The first ear plate and the second ear plate are hingedly connected to the motor vehicle.

[0079] The suspension bracket 9 is suspended at three points with the motor vehicle to form a stable triangular structure, which can support and adjust the working angle and depth of the mixed fertilizer tillage machine. The advantage of the three-point suspension is its flexibility and adaptability, which can be adjusted according to different operating requirements. For example, the mixed fertilizer tillage machine can maintain a full-width working state when turning, reducing the impact on the lateral load.

[0080] Optionally, the lower end of the mixing box 4 is cylindrical and adapted to the shape of the second auger, and the upper end of the mixing box 4 is prism-shaped, the fertilizer box 2 and the organic fertilizer box 3 are installed at the larger end of the prism-shaped, and the cylindrical side wall is connected at the smaller end of the prism-shaped.

[0081] The upper end of the mixing box 4 can guide the mixed fertilizer entering the mixing box 4 to avoid the mixed fertilizer from piling up at the upper end of the mixing box 4. The lower end of the mixing box 4 is adapted to the shape of the second auger so that the second auger can evenly crush and transport the mixed fertilizer entering the lower end of the mixing box 4.

[0082] Optionally, the fertilizer box 2 and the organic fertilizer box 3 are also hopper-shaped.

[0083] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in this application (but not limited to) to form a technical solution.
