Description

Technical Field

[0001] This utility model relates to the field of multi-functional deep tillage machine technology, specifically a multi-functional deep tillage machine with variable fertilization capability. Background Technology

[0002] In agricultural production, deep tillage and scientific fertilization are two core elements for improving crop yield and quality. Deep tillage can break up the plow pan, enhance soil aeration and water and fertilizer retention capacity, and create a good environment for crop root growth. Precision fertilization provides nutrients according to the crop's growth needs. The synergy between the two plays a decisive role in agricultural production efficiency.

[0003] In traditional agricultural operations, deep plowing and fertilization are often carried out in separate steps: first, the soil is tilled using deep plowing equipment, and then fertilizer is applied manually or using separate fertilization equipment. This method not only requires a large investment of manpower and resources and has low efficiency, but also has a time difference between the two processes, which can easily lead to the soil structure becoming compacted again while waiting for fertilization. At the same time, the fertilizer is exposed to the surface for a long time and is affected by natural factors such as wind and rain, resulting in serious volatilization and loss, which greatly reduces the fertilizer utilization rate. This increases agricultural production costs and may also cause soil pollution due to excessive fertilizer residue.

[0004] In the existing technology, some deep tillage equipment has realized intelligent adjustment of the deep tillage process. For example, the "deep tillage machine" with application number CN202510044911.2 monitors the angle of the lifting arm through an angle acquisition device, and the controller controls the adjustment component to adjust the distance between the plow blade and the ground in real time to ensure that the deep tillage depth is always maintained within the preset range, which effectively improves the stability and consistency of deep tillage operation. However, this type of equipment only focuses on the precise control of deep tillage depth and does not have a synchronous fertilization mechanism. In practical applications, fertilization still needs to be carried out manually after the deep tillage operation is completed. This not only continues the inefficiency problem of traditional step-by-step operation, but may also cause crop nutrient absorption imbalance due to the unevenness of manual fertilization, and adds extra labor costs. It is difficult to meet the "efficient, precise and collaborative" operation requirements of modern agriculture.

[0005] In addition, some combined tillage and fertilization equipment on the market also has many limitations: some equipment has a simple fertilizer adjustment mechanism, which cannot achieve precise variable fertilization according to crop variety, growth stage and soil fertility, and is prone to over-fertilization or under-fertilization; some equipment has poor coordination between the fertilization mechanism and the deep tillage mechanism, and the fertilizer placement position is not well matched with the deep tillage area, which affects the mixing effect of fertilizer and soil; some equipment has problems such as fertilizer blockage and unstable delivery due to unreasonable structural design, which further restricts the efficiency and quality of operation.

[0006] Based on this, this proposal puts forward a solution of "a multi-functional deep tillage machine with variable fertilization". Utility Model Content

[0007] The purpose of this invention is to provide a multi-functional deep tillage machine with variable fertilization to solve the problem mentioned in the background art that existing equipment on the market is not equipped with a synchronous fertilization mechanism and still needs to be fertilized manually after the deep tillage operation is completed.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional deep tillage machine with variable fertilization, comprising a support frame, a tillage head, a first fixed frame, a second fixed frame, and an adjustment groove;

[0009] The support frame is provided with a fertilizer application mechanism on its side. The fertilizer application mechanism includes a hopper, a discharge pipe, a insert plate, an auger, and an adjustment groove. The auger is installed inside the discharge pipe and is located on the side of the motor. The adjustment groove is located above the discharge pipe, and the insert plate is installed above the adjustment groove.

[0010] As a preferred technical solution of this utility model, the support frame is a grid-shaped structure, and the tiller head is fixedly connected to the bottom of the support frame. There are two tiller heads symmetrically distributed. The tiller head is a conical structure, and the side of the tiller head is provided with a figure-eight guide plate. The support frame and the tiller head are an L-shaped structure.

[0011] By adopting the above technical solution, the support frame adopts a grid-shaped structure, which can significantly improve the stability and load-bearing capacity of the overall structure. It can effectively cope with the reaction force of the soil on the equipment during deep tillage operations, reduce equipment shaking, and the two symmetrically distributed conical tillage heads, together with the V-shaped guide plates on the sides, can not only easily cut into the soil during deep tillage, but also guide the turned soil to both sides in an orderly manner, avoiding soil accumulation that affects subsequent operations. The L-shaped overall structure formed by the support frame and the tillage head further ensures the stability of the tillage head's soil entry angle, making the tillage depth more uniform and improving the quality of deep tillage.

[0012] As a preferred technical solution of this utility model, a first fixed frame is fixedly connected above the support frame, a discharge pipe is fixedly connected at the center line of the first fixed frame, and the two sides of the first fixed frame are hollow structures. An auger is rotatably connected inside the discharge pipe, the side of the auger is fixedly connected to the motor output shaft, and a feed port is provided above the discharge pipe.

[0013] Using the above technical solution, the first fixed frame, which is fixedly connected above the support frame, has a hollow structure on both sides that reduces the overall weight of the equipment and makes it easier for operators to observe the working status of the fertilization mechanism, reducing maintenance difficulty. The discharge pipe, which is fixed at the center of the first fixed frame, works in conjunction with the auger that is rotated inside. Driven by the motor, it can deliver fertilizer evenly and stably to the soil, avoiding the problem of uneven fertilizer distribution in traditional fertilization methods. The inlet above the discharge pipe ensures that fertilizer can smoothly enter the discharge pipe, ensuring the continuity of the fertilization process.

[0014] As a preferred technical solution of this utility model, a second fixed frame is fixedly connected above the first fixed frame. The second fixed frame is an equilateral trapezoidal structure and is symmetrically distributed on both sides of the upper surface of the first fixed frame. Connecting sleeves are fixedly connected to the sides of the second fixed frame. There are four connecting sleeves in total, which are distributed in a rectangular shape.

[0015] Using the above technical solution, the second fixed frame, which is an equilateral trapezoidal structure fixed above the first fixed frame, is symmetrically distributed on both sides of the upper surface of the first fixed frame. This structural design can provide stable support for the hopper above, disperse the pressure generated when the hopper is full of fertilizer, and prevent the fixed frame from deforming. The four rectangular connecting sleeves can enhance the stability of the connection between the second fixed frame and other components, ensure that the components are firmly connected during the operation of the equipment, reduce the loosening of components caused by vibration, and extend the service life of the equipment.

[0016] As a preferred technical solution of this utility model, a hopper is slidably connected above the second fixed frame. The hopper has a trapezoidal funnel-shaped structure, and connecting sleeves are fixedly connected to both sides of the hopper. A screw is slidably connected inside the connecting sleeve. A hook structure is provided at the top of the screw, and an external thread structure is provided at the bottom of the screw. The screw is connected to the second fixed frame through the connecting sleeve below.

[0017] Using the above technical solution, the trapezoidal funnel-shaped hopper slidably connected above the second fixed frame is designed to facilitate the smooth falling of fertilizer and reduce fertilizer residue in the hopper. The connecting sleeves on both sides of the hopper are slidably connected to the screw. By adjusting the screw, the height and position of the hopper can be flexibly changed to adapt to different fertilizer dispensing needs. The hook structure at the top of the screw facilitates the connection between the equipment and the traction machinery, while the external thread structure at the bottom can be firmly connected to the second fixed frame through the connecting sleeve, ensuring the stability of the hopper's position during operation and preventing fertilizer spillage due to bumps.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The support frame adopts a grid-shaped structure, which improves the overall stability and load-bearing capacity, can cope with the reaction force of the soil during deep plowing, and reduce shaking. The two symmetrical conical tillage heads, together with the figure-eight guide plates, can easily enter the soil and guide the soil to both sides to avoid accumulation. The L-shaped structure of the support frame and tillage head ensures that the tillage head enters the soil at a stable angle, making the tillage depth uniform and effectively improving the quality of deep plowing.

[0020] 2. The hollow design on both sides of the first fixed frame reduces the weight of the equipment, makes it easier to observe the status of the fertilization mechanism, and reduces the difficulty of maintenance. Its fixed connection with the discharge pipe, combined with the cooperation of the auger and the motor, can deliver fertilizer evenly and stably, solving the problem of uneven fertilization in traditional fertilization. The feed inlet above the discharge pipe ensures the continuity of fertilizer supply and improves fertilization efficiency.

[0021] 3. The second fixed frame with an equilateral trapezoidal structure is symmetrically distributed, providing stable support for the hopper, dispersing the weight of the fertilizer, preventing deformation of the fixed frame, and the four rectangular connecting sleeves enhance the connection stability with other components, reduce component loosening caused by vibration during operation, extend the service life of the equipment, and ensure the overall reliability of operation.

[0022] 4. The trapezoidal funnel-shaped hopper facilitates fertilizer drop and reduces residue. The hopper is slidably connected to the screw via a connecting sleeve, allowing for flexible adjustment of height and position to meet different fertilization needs. The hook at the top of the screw facilitates connection with traction machinery, and the external thread structure at the bottom ensures a stable connection with the second fixed frame, preventing fertilizer spillage due to bumps during operation and improving the accuracy of fertilization.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 - Figure 5 The present invention provides a multi-functional deep tillage machine with variable fertilization, comprising a support frame 1, a tillage head 2, a first fixed frame 3, a second fixed frame 4, a hopper 5, a drive block 6, a connecting sleeve 7, a screw 8, a motor 9, a discharge pipe 10, an insert plate 11, an auger 12, and an adjustment groove 13.

[0031] This utility model integrates the deep tillage mechanism and the variable fertilization mechanism into the same support frame 1, realizing the integrated operation of tillage and fertilization. It breaks the step-by-step mode of "tillage first, fertilization later" in traditional agricultural production, and greatly shortens the operation time per unit area of ​​land. The grid-shaped support frame 1 serves as the core support structure. Its crisscrossing beam design can evenly distribute the impact force generated during tillage. Combined with the L-shaped rigid connection formed with the tillage head 2, it maintains a stable posture throughout the tillage process, avoiding machine shaking caused by uneven ground or soil resistance, and laying the foundation for subsequent precise fertilization.

[0032] The tip angle of the conical tiller head 2 is optimized to reduce tillage resistance by decreasing the contact area with the soil, making it easier for the equipment to cut into compacted soil. The V-shaped guide plates on the side not only push the tilled soil to both sides to form a flat tillage zone, but also leave shallow trenches in the soil suitable for fertilizer burial, reducing the volatilization loss of fertilizer exposed to the surface. The two symmetrically distributed tiller heads 2 form a mirror tillage trajectory during operation. Combined with the guiding effect of the guide plates, the structure of the tilled soil is looser, creating favorable conditions for the full mixing of fertilizer and soil and improving fertilizer absorption efficiency.

[0033] The core advantage of the fertilizer application mechanism lies in its dual characteristics of "controllable variables" and "stable delivery". The inner wall of the trapezoidal funnel-shaped hopper 5 is made of smooth and wear-resistant material. Its tilt angle design can guide the fertilizer to fall naturally by gravity, avoiding blockage caused by fertilizer clumping. The auger 12 in the discharge pipe 10 is driven by the motor 9 to achieve uniform rotation, continuously and evenly pushing the fertilizer to the discharge port, solving the problem of fertilizer "interruption" or "accumulation" in the traditional gravity feeding method.

[0034] The design of the adjustment groove 13 and the insert plate 11 provides an intuitive and precise way to adjust the amount of fertilizer: by sliding the insert plate 11 to change its blocking area on the feed inlet of the discharge pipe 10, the amount of fertilizer entering the conveying area of ​​the auger 12 can be adjusted in real time. Combined with the adjustment of the speed of the motor 9 to control the conveying speed of the auger 12, it is possible to achieve multi-level fine control of the amount of fertilizer, meet the differentiated needs of different crops for fertilizer concentration from the seedling stage to the mature stage, avoid soil pollution caused by excessive fertilizer, and prevent insufficient fertilizer from affecting crop growth.

[0035] The hierarchical connection design of the first fixed frame 3 and the second fixed frame 4 not only ensures the rigid fixation of the fertilization mechanism and the support frame 1, but also reduces the weight of the equipment through the hollow structure of the first fixed frame 3, making it easier for operators to observe the fertilization status and the operation of the tiller 2 in real time, and reducing the difficulty of equipment maintenance. The equilateral trapezoidal structure of the second fixed frame 4 and the rectangularly distributed connecting sleeves 7 form a stable support system, which can evenly transfer the weight of the hopper 5 to the support frame 1, avoiding structural deformation caused by excessive local stress.

[0036] The sliding fit between the screw 8 and the connecting sleeve 7 gives the equipment good adaptability: the height of the hopper 5 can be flexibly adjusted by rotating the screw 8 to meet the feeding needs of fertilizers of different particle sizes, such as powdered organic fertilizer and granular compound fertilizer; the top hook structure facilitates quick docking of the equipment with tractors and other traction machinery, and the external thread design at the bottom ensures that the hopper 5 is stable in position during operation through the thread self-locking effect, effectively avoiding fertilizer spillage caused by road bumps or tillage vibration, and further improving the accuracy of fertilization operations.

[0037] Working principle: When using a multi-functional deep tiller with variable fertilization, the support frame 1 serves as the overall support structure. Its grid-shaped design ensures stability during operation. The two symmetrical conical tillage heads 2 fixed below it cut into the soil under the traction of the traction device. The pointed ends of the conical structure reduce the resistance to soil entry and easily break up compacted soil. The V-shaped guide plates on the sides of the tillage heads 2 move forward with the equipment, guiding the turned soil to both sides in an orderly manner to avoid soil accumulation and form a flat tillage zone. At the same time, the L-shaped structure formed by the support frame 1 and the tillage heads 2 ensures that the tillage head 2 has a stable entry angle and ensures uniform tillage depth, creating a suitable soil environment for subsequent fertilization.

[0038] The hopper 5 serves as a fertilizer storage component. Its trapezoidal funnel-shaped structure uses gravity to guide the fertilizer to fall naturally and enter the discharge pipe 10 through the inlet above the discharge pipe 10.

[0039] Motor 9 drives the auger 12 inside the discharge pipe 10 to rotate. The blades of the auger 12 continuously push the fertilizer, so that the fertilizer is evenly delivered to the soil along the discharge pipe 10, avoiding the problems of discontinuity or accumulation in traditional fertilization.

[0040] By changing the area of ​​the sliding plate 11 covering the regulating groove 13, the amount of fertilizer entering the discharge pipe 10 can be controlled; combined with the motor 9's regulation of the auger 12's speed, the fertilizer conveying speed can be further flexibly adjusted to adapt to the fertilization needs of different crops and different soils, thus realizing variable fertilization.

[0041] The first fixed frame 3 and the second fixed frame 4 serve as connecting carriers, firmly combining the fertilization mechanism with the support frame 1: the discharge pipe 10 is fixed in the center line of the first fixed frame 3 to ensure that the fertilization path is aligned with the tillage belt; the second fixed frame 4 is connected to the hopper 5 through the connecting sleeve 7 and the screw 8. The screw 8 can adjust the height and position of the hopper 5 to ensure that the fertilizer enters the discharge pipe 10 smoothly. At the same time, it is connected to the traction equipment through the top hook to realize the stable movement and operation of the whole machine.

[0042] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
