Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery and equipment, and in particular to a fertilizing and cultivating land integrated device and a fertilizing and cultivating land method. Background Art

[0002] In agricultural production, fertilization and tillage are key links in the crop planting process, directly impacting crop growth and ultimate yield, and playing a vital role in sustainable agricultural development and food security. With the advancement of agricultural modernization, the demand for efficient and precise agricultural machinery and equipment is growing. The research and development and application of integrated fertilization and tillage devices have become a key development direction in the agricultural machinery sector.

[0003] Currently, there are many types of fertilization equipment on the market. Common fertilization mechanisms include screw conveyor and centrifugal spreaders. The screw conveyor pushes fertilizer through the rotation of spiral blades, which can achieve a certain degree of fertilization on relatively flat terrain and at a stable speed. Centrifugal spreaders use a high-speed rotating spreader to spread fertilizer, allowing for wide-area fertilization. For arable land, most equipment uses traditional plowing methods, turning the soil with a plow.

[0004] However, existing equipment has drawbacks in its fertilization mechanisms. For example, methods like spiral conveying and centrifugal spreading are easily affected by vehicle speed. When vehicle speed fluctuates, spiral conveying mechanisms cannot precisely control the amount of fertilizer delivered, while centrifugal spreading mechanisms struggle to ensure uniform fertilizer distribution. This results in uneven fertilizer distribution during actual operation if vehicle speed fluctuates. Summary of the Invention

[0005] The embodiments of the present application solve the problem in the prior art of uneven fertilization due to the influence of the equipment's travel speed by providing an integrated device for fertilizing cultivated land and a method for fertilizing cultivated land, thereby improving the quality and efficiency of fertilizing cultivated land operations.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a fertilizing and tilling land integrated device, including a traction frame, the front end of the traction frame can be connected to the traction vehicle, the rear end of the traction frame is connected to a support frame, a fertilizer hopper is installed above the support frame, a fertilizer pipe is installed at the bottom of the fertilizer hopper, and walking wheels are installed on both sides of the traction frame, the two walking wheels are connected by a first rotating shaft, and a first sprocket is fixed to the outside of the first rotating shaft; a fertilizer box is installed at the bottom of the fertilizer hopper, the fertilizer box is connected to the fertilizer pipe, a rotating roller handle is installed in the fertilizer box, and a second rotating shaft passes through it, the outside of the second rotating shaft is fixed to the rotating roller, the outer wall of the rotating roller is provided with a strip groove, and the length direction of the strip groove is consistent with the axial direction of the rotating roller; a second sprocket is also fixed to the outside of the second rotating shaft, and the second sprocket and the first sprocket are jointly surrounded by a chain.

[0007] When the traction vehicle drives the traction frame forward, the running wheels roll on the ground. The rolling of the running wheels drives the first rotating shaft to rotate, which in turn causes the first sprocket to rotate. Through the transmission of the chain, the second sprocket drives the second rotating shaft to rotate, and finally causes the rotating roller to rotate. During the rotation process, the strip grooves on the outer wall of the rotating roller bring out the fertilizer in the fertilizer box and drop it into the fertilizer pipe, realizing the fertilizer transportation and fertilization operations. Due to the characteristics of the chain transmission, when the travel speed of the traction frame changes, the rotation speed of the rotating roller will also change accordingly, thereby ensuring that the fertilizer falling speed matches the travel speed of the device. This solves the problem of uneven fertilization caused by speed changes in traditional fertilization equipment, makes the distribution of fertilizer in the farmland more even, reduces local fertilizer damage or insufficient fertilizer efficiency, and improves the utilization efficiency of fertilizer.

[0008] As a further improvement of the above scheme, the support frame includes two vertical plates, the second rotating shaft is rotatably installed between the two vertical plates, the tops of the two vertical plates are supported under the fertilizer hopper, and the bottoms of the two vertical plates are connected by two parallel first square tubes and second square tubes, the second square tube is located behind the first square tube, and the first square tube is connected to the rear end of the traction frame; multiple fertilizer assemblies are installed on the first square tube, and multiple cultivated land assemblies are installed on the second square tube, and the cultivated land assemblies and the fertilizer assemblies are staggered.

[0009] As a further improvement of the above solution, the fertilization assembly includes a connecting handle A, the upper end of the connecting handle A is fixed to the first square tube, the lower end of the connecting handle A is fixed with a fertilizer plow, and the rear side of the fertilizer plow is fixed to the lower end outer wall of the fertilizer tube.

[0010] As a further improvement of the above solution, the tillage assembly includes a connecting handle B, the upper end of the connecting handle B is fixed to the second square tube, and the lower end of the connecting handle B is fixed with a tillage plow.

[0011] As a further improvement of the above scheme, a connecting rod is hinged on the rear side of the first square tube, and a third sprocket is rotatably installed on the upper end of the connecting rod. The third sprocket engages with the inner side of the chain. A tension spring is connected to one side of the connecting rod, and the other end of the tension spring is connected to the front side of the second square tube.

[0012] As a further improvement of the above scheme, the traction frame includes a fixed frame and a movable frame. The fixed frame includes two longitudinal tubes. The rear ends of the two longitudinal tubes are fixed to the first square tube. The first transverse tube and the second transverse tube are connected between the two longitudinal tubes. The front side of the first transverse tube is fixed with a connecting seat that can be hinged to the traction vehicle, and the middle part of the second transverse tube is threadedly installed with a stud; the front end of the movable frame is located below the second transverse tube and is rotatably connected to the lower end of the stud, the rear end of the movable frame is hinged to the first square tube, and a bearing seat is installed at the bottom of the movable frame, and the first rotating shaft is installed in the bearing seat through a bearing.

[0013] As a further improvement of the above solution, a brush is fixed to the inner wall of the fertilizing box, and the lower end of the brush can contact the outer periphery of the rotating roller.

[0014] The present invention also discloses a method for fertilizing cultivated land, which adopts the above-mentioned integrated device for fertilizing cultivated land and specifically comprises the following steps: Step 1: Secure the connecting seat to the rear end of the towing vehicle; Step 2: Rotate the studs so that the lower ends of the fertilizing assembly and the tillage assembly can be buried in the soil surface; Step 3: Add fertilizer into the fertilizer hopper and start the traction vehicle to drive the device forward.

[0015] As a further improvement of the above scheme, in step three, when the traction vehicle drives the device forward, the walking wheel rolls with the ground and drives the first rotating shaft and the first sprocket to rotate, and drives the second sprocket and the second rotating shaft to rotate through the chain; the strip groove on the rotating roller carries the fertilizer from the fertilizer box to the fertilizer pipe, and the fertilizer is guided through the fertilizer pipe to the soil groove opened by the fertilizer plow, and then the fertilized soil is plowed by the tillage plow.

[0016] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: Since the walking wheel and the rotating roller are connected by a chain drive, the falling speed of the fertilizer can be correlated with the travel speed of the device. This effectively solves the technical problem in the prior art that the fertilizer mechanism is easily affected by the undulations of the terrain or the travel speed of the equipment, resulting in uneven distribution of fertilizer, thereby achieving a more uniform distribution of fertilizer and reducing local fertilizer damage or insufficient fertilizer efficiency. At the same time, the fixed frame and movable frame structure and the setting of the stud adjustment enable the device to adapt to different traction vehicles. When connecting to traction vehicles of different models, the angle of the movable frame can be adjusted by rotating the stud, thereby changing the height of the first rotating shaft and optimizing the height and angle of the entire device. This ensures that the fertilizer plow and the tillage plow, driven by different traction vehicles, can contact the soil at an appropriate depth and angle, function more effectively, improve the quality of fertilization and tillage, and enhance the versatility and adaptability of the device.

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of this patent, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of this patent.

[0020] The present invention discloses a fertilizing and cultivating land integrated device, such as Figures 1 to 5 The device comprises a traction frame, a support frame 1, a fertilizer hopper 2, a fertilizer pipe 3, and running wheels 4. The traction frame serves as a connector and support for the entire device. A connecting structure for connecting to a towing vehicle is provided at the front end of the traction frame. This connecting structure is rotatably connected to the rear end of the towing vehicle via bolts or pins. This allows the device to follow the towing vehicle during operation, effectively transmitting the power provided by the towing vehicle.

[0021] The rear end of the traction frame is connected to the support frame 1. The support frame 1 comprises two vertical plates 13, a first square tube 14, and a second square tube 15. Both vertical plates 13 are arranged vertically and are rectangular or trapezoidal in shape. A second rotating shaft 8 is mounted above the vertical plates 13 and rotatably mounted between the two vertical plates 13.

[0022] The top of the vertical plate 13 supports the fertilizer hopper 2. The fertilizer hopper 2 is a long, trough-like structure with an upward-facing opening. The upper opening is larger than the lower opening, facilitating the centralized storage and downward transportation of fertilizer. A fertilizer pipe 3 is mounted at the bottom of the fertilizer hopper 2, ensuring smooth fertilizer delivery from the hopper 2 to the application area.

[0023] Two running wheels 4 are provided, symmetrically mounted on either side of the traction frame and connected by a first rotating shaft 5. A first sprocket 6 is secured to the exterior of the first rotating shaft 5, and the first rotating shaft 5 and the first sprocket 6 can be secured using a key connection. The running wheels 4 can be made of metal, and multiple steel bars can be secured to their outer circumference. These bars are arranged along the circumference to ensure the device's maneuverability through farmland.

[0024] Specifically, in this embodiment, a fertilizer box 7 is mounted at the bottom of the fertilizer hopper 2, and the bottom of the fertilizer box 7 is connected to the fertilizer pipe 3. A second rotating shaft 8 extends through the fertilizer box 7, and a rotating roller 9 is fixed to the outside of the second rotating shaft 8. The outer wall of the rotating roller 9 is provided with a strip groove 10, and the length direction of the strip groove 10 is consistent with the axial direction of the rotating roller 9. When the rotating roller 9 rotates, the fertilizer in the fertilizer box 7 falls into the fertilizer pipe 3 through the strip groove 10. A second sprocket 11 is also fixed to the outside of the second rotating shaft 8. The second sprocket 11 and the first sprocket 6 are co-circled with a chain 12. Thus, by transmitting power through the chain 12, the second rotating shaft 8 can rotate synchronously with the first rotating shaft 5.

[0025] When the traction vehicle drives the traction frame forward, the running wheel 4 rolls on the ground. The rolling of the running wheel 4 drives the first rotating shaft 5 to rotate, and then the first sprocket 6 rotates accordingly. Through the transmission of the chain 12, the second sprocket 11 drives the second rotating shaft 8 to rotate, and finally the rotating roller 9 rotates. During the rotation process, the strip groove 10 on the outer wall of the rotating roller 9 brings out the fertilizer in the fertilizer box 7 and drops it into the fertilizer pipe 3, realizing the fertilizer transportation and fertilization operation. Due to the characteristics of the chain transmission, when the travel speed of the traction frame changes, the rotation speed of the rotating roller 9 will also change accordingly, thereby ensuring that the fertilizer falling speed matches the travel speed of the device. This solves the problem of uneven fertilization caused by speed changes in traditional fertilization equipment, reduces local fertilizer damage or insufficient fertilizer efficiency, and improves the utilization efficiency of fertilizer.

[0026] Combine Figure 1 、 Figure 2 、 Figure 3 As shown, multiple fertilizer assemblies are mounted on the first square tube 14. Each fertilizer assembly includes a connecting handle A16 and a fertilizer plow 17. The connecting handle A16 is bar-shaped, and its upper end is bolted to the first square tube 14. The bolt connection facilitates the installation and removal of the connecting handle A16, facilitating subsequent maintenance and replacement. The lower end of the connecting handle A16 is fixed to the fertilizer plow 17, which comprises two plate-like structures that are approximately triangular. The lower end of the fertilizer plow 17 is pointed and tilted forward, effectively reducing resistance when inserted into the soil and making it easier for the fertilizer plow 17 to enter the soil. The rear side of the fertilizer plow 17 is connected to the lower outer wall of the fertilizer tube 3 to ensure that fertilizer can smoothly fall from the fertilizer tube 3 into the soil area where the fertilizer plow 17 is operating. As the device moves forward, the fertilizer plow 17 can create a groove in the soil, allowing fertilizer to be applied more deeply into the soil and improving fertilizer utilization.

[0027] Combine Figure 1 、 Figure 2 、 Figure 3As shown, the second square tube 15 is located behind the first square tube 14, and a plurality of tillage components are installed on the second square tube 15. In the front-to-back direction of the device, the tillage components and the fertilization components are staggered, that is, any one tillage component is located between two fertilization components. This staggered arrangement enables fertilization and tillage operations to be carried out sequentially in adjacent areas, avoiding repeated operations and idle strokes, and improving work efficiency. Specifically, each tillage component includes a connecting handle B18 and a tillage plow 19. The connecting handle B18 has a similar structure to that of the connecting handle A16, and the upper end of the connecting handle B18 is fixed to the second square tube 15 by a bolt connection. The tillage plow 19 is composed of two sheet-like structures, and the sheet-like structure is triangular. The lower end of the tillage plow 19 is sharp and tilted forward, thereby effectively reducing the resistance when inserted into the soil, making it easier for the tillage plow 19 to enter the soil.

[0028] like Figure 3 As shown, a connecting rod 20 is hingedly connected to the rear side of the first square tube 14. The connecting rod 20 is a bar-shaped structure, with its lower end hinged to the rear side of the first square tube 14 via a hinge axis. A third sprocket 21 is rotatably mounted on the upper end of the connecting rod 20. The third sprocket 21 engages the inner side of the chain 12, meaning that the chain 12 wraps around the outside of the first sprocket 6, the second sprocket 11, and the third sprocket 21. A tension spring 22 is connected to one side of the connecting rod 20, the other end of which is connected to the front side of the second square tube 15. The tension spring 22 is always in tension, applying a pulling force to the connecting rod 20 toward the second square tube 15, keeping the third sprocket 21 tightly against the chain 12. During operation, the tension of the chain 12 affects the stability of power transmission. If the chain 12 is too loose, it is prone to loosening and slipping, affecting the normal operation of the fertilizing device. If the chain 12 is too tight, it will increase wear on the chain 12 and shorten the service life of the device. In this embodiment, the connection rod 20 and the tension spring 22 are provided so that the chain 12 can maintain appropriate tension, thereby improving the reliability and stability of the chain 12 transmission, reducing failures caused by looseness of the chain 12, and extending the service life of the equipment.

[0029] Combine Figures 1 to 3As shown, the traction frame includes a fixed frame 24 and a movable frame 25. The fixed frame 24 includes two parallel longitudinal tubes 31. The rear ends of the two longitudinal tubes 31 are fixed to the first square tube 14, and the connection method can be welding. The welding method can provide a higher connection strength, so that the fixed frame 24 and the first square tube 14 form a whole. A first transverse tube 26 and a second transverse tube 27 are connected between the two longitudinal tubes 31. The setting of the first transverse tube 26 and the second transverse tube 27 enhances the overall strength of the fixed frame 24, so that the fixed frame 24 can better withstand various forces during the operation process, such as traction, soil resistance, etc. A connecting seat 28 is fixed to the front side of the first transverse tube 26. The connecting seat 28 can be hinged to the traction vehicle, and the device can flexibly follow the steering of the traction vehicle through the hinged method. A stud 29 is threadedly installed in the middle of the second transverse tube 27 ( Figure 5 ), when the stud 29 rotates, it can move up and down relative to the cross tube. The front end of the movable frame 25 is located below the second cross tube 27 and is rotatably connected to the lower end of the stud 29. The rear end of the movable frame 25 is hinged to the first square tube 14. A bearing seat 32 is installed at the bottom of the movable frame 25, and the first rotating shaft 5 is installed in the bearing seat 32 through a bearing. By rotating the stud 29, the angle of the movable frame 25 can be adjusted, and then the height of the first rotating shaft 5 can be adjusted. This adjustment structure allows the device to adapt to different terrains and operating requirements. For example, when working in farmland with large terrain, the stud 29 can be adjusted so that the lower end of the fertilizer plow and the tillage plow can contact the soil at an appropriate depth and angle to ensure the quality of fertilization and tillage operations; when connecting to different types of tractor vehicles, the angle of the movable frame 25 can also be changed by rotating the stud 29, so that the height and angle of the entire device can be adjusted, enhancing the versatility and adaptability of the device.

[0030] Combine Figure 3 、 Figure 4As shown, a brush 30 is fixed to the inner wall of the fertilizer box 7. The brush 30 is in the shape of an elongated strip, and the upper part of the brush 30 is fixed to the inner wall of the fertilizer box 7 by means of bolts. The width and hardness of the brush 30 are selected according to the size of the rotating roller 9 and the characteristics of the fertilizer. For fertilizers with larger particles, a harder brush 30 can be selected to better block the fertilizer and prevent it from falling too quickly; for fertilizers with smaller particles, a softer brush 30 can be selected to avoid damaging the rotating roller 9. The lower end of the brush is in close contact with the outer periphery of the rotating roller 9. During the operation of the device, when the traction frame moves slowly and the rotating roller 9 rotates slowly therewith, the fertilizer may fall quickly due to factors such as its own gravity, resulting in uneven fertilization. At this time, the brush 30 can play a role. It can provide a certain degree of blocking effect on the fertilizer in the strip groove 10 on the outer wall of the rotating roller 9, slowing down the fertilizer's falling speed so that it matches the rotation speed of the rotating roller 9 and prevents the fertilizer from falling too quickly, thereby ensuring the continuity and uniformity of fertilization, ensuring a stable amount of fertilizer each time, and improving the quality of fertilization. At the same time, the brush 30 can also clean the fertilizer residue on the rotating roller 9, preventing fertilizer from clogging the strip groove 10, ensuring the normal operation of the fertilization device and improving the reliability of the equipment.

[0031] The present invention also discloses a method for fertilizing cultivated land, which uses the above-mentioned integrated fertilizing and cultivating land device, and the specific steps are as follows: Step 1: Fix the connecting seat 28 to the rear end of the towing vehicle.

[0032] Step 2: Rotate the stud 29 so that the lower ends of the fertilizing assembly and the tillage assembly can be buried in the soil surface. Before rotating the stud 29, it is necessary to determine the appropriate burial depth based on the soil texture and crop planting requirements. Generally speaking, the depth is controlled at around 3-10 cm. For soils with a harder texture, such as clay, in order to ensure that the fertilizer can be effectively applied to the soil and the tillage operation can achieve the desired effect, it may be necessary to adjust the depth to 8-10 cm; for soils with a looser texture, such as sandy soil, the depth can be controlled at 3-5 cm. When rotating the stud 29, use a suitable tool, such as a wrench, to rotate the stud 29 and observe the descent of the fertilizing assembly and the tillage assembly to ensure that they descend evenly to avoid tilting or getting stuck. After the adjustment is completed, check the position of the fertilizing assembly and the tillage assembly again to ensure that their lower ends can be accurately buried in the soil surface to the expected depth.

[0033] Step 3: Add fertilizer to the fertilizer hopper 2 and start the traction vehicle to drive the device forward. Specifically, when the traction vehicle drives the device forward, the running wheel 4 rolls with the ground and drives the first rotating shaft 5 and the first sprocket 6 to rotate, which in turn drives the second sprocket 11 and the second rotating shaft 8 to rotate via the chain 12. The strip groove 10 on the rotating roller 9 carries the fertilizer from the fertilizer box 7 to the fertilizer pipe 3. The fertilizer is guided through the fertilizer pipe 3 to the soil groove created by the fertilizer plow 17. The cultivated land plow 19 then plows the fertilized soil.

[0034] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: Since the chain 12 is used to connect the walking wheel 4 and the rotating roller 9, the falling speed of the fertilizer can be correlated with the travel speed of the device. This effectively solves the problem in the prior art that the fertilizer application mechanism is easily affected by the travel speed of the equipment, resulting in uneven distribution of fertilizer application, and reduces the situation of local fertilizer damage or insufficient fertilizer efficiency. At the same time, the arrangement of the fixed frame 24, the movable frame 25 and the stud 29 enables the device to adapt to different traction vehicles. When connecting to traction vehicles of different models, the angle of the movable frame 25 can be adjusted by rotating the stud 29, thereby optimizing the height and angle of the entire device. This ensures that the fertilizer plow 17 and the tillage plow 18, driven by different traction vehicles, can contact the soil at an appropriate depth and angle, play a more effective role, and improve the quality of fertilization and cultivated land.
