Description

Technical Field

[0001] This invention relates to the technical field of ridging and fertilization devices, and more particularly to a ridging and fertilization device for farmland reclamation. Background Technology

[0002] In agricultural production, ridging and fertilization is a crucial step in cultivation, especially for crops such as potatoes, corn, and cotton. A reasonable ridge width design directly affects crop root development, ventilation and light penetration, as well as water and fertilizer utilization efficiency.

[0003] Patent CN114830857B discloses a double-helix ridging and fertilizing device, including a fertilizer bin for storing fertilizer, a crusher inside the fertilizer bin for breaking up the fertilizer, fertilizer in the upper layer of the fertilizer bin being broken up by the crusher and falling into the lower layer, and a spreading mechanism connected to the outlet of the fertilizer bin for spreading the fertilizer onto the farmland. The above patent has some defects in its use:

[0004] 1. The above-mentioned patent uses a soil covering plate to rid the soil. Although the soil covering plate can be adjusted by swinging up and down to adjust the tilt angle, the shape and position of the soil covering plate are relatively fixed, and the ridge width parameter of ridging with the soil covering plate is fixed. It is difficult to adapt to the agronomic requirements of different crops. When it is necessary to adjust the ridge width, the operator must use tools to disassemble the bolts, replace the soil covering plate or replace the entire ridging component, which is time-consuming and reduces the efficiency of operation. In addition, frequent disassembly can easily lead to wear of the connecting parts and affect the stability of the equipment.

[0005] 2. The fertilization rate of the above-mentioned patent will always remain consistent and cannot be dynamically adjusted according to the movement status of the entire device. When the entire device encounters an obstacle and slows down or stops moving, the fertilizer will continue to be discharged, which will cause excessive fertilization in local areas and cause it to accumulate into clumps. This will not only waste fertilizer, but may also affect the uniformity of crop growth. Summary of the Invention

[0006] In view of this, the present invention provides a ridging and fertilizing device for farmland reclamation, which can overcome the shortcomings of traditional ridging and fertilizing devices, which usually have fixed ridge width parameters, making it difficult to adjust the ridge width parameters according to the agronomic requirements of different crops, and the fertilization rate cannot be dynamically adjusted according to the movement status of the entire device.

[0007] The technical solution is as follows: a ridging and fertilizing device for farmland reclamation, comprising: a mounting frame; a connecting frame connected to the mounting frame; a controller installed on the side of the connecting frame; a ridging plate symmetrically slidably connected to the mounting frame; a first electric push rod symmetrically installed on the mounting frame, and the telescopic rod of the first electric push rod is connected to the ridging plate; a rotary tillage component set on the ridging plate for loosening the soil; and a fertilization component set on the ridging plate for fertilization.

[0008] As a further preferred embodiment, the rotary tillage assembly includes: a first rotary cylinder rotatably connected to one of the ridging plates; a second rotary cylinder rotatably connected to the other ridging plate, and the second rotary cylinder being slidably connected to the first rotary cylinder; rotary tillage blades, respectively and spaced apart from the first and second rotary cylinders; and a rotation mechanism disposed on a mounting frame for driving the first and second rotary cylinders to rotate.

[0009] As a further preferred embodiment, the rotating mechanism includes: a first rotating rod rotatably connected to the ridging plate; a pulley assembly, through which the first rotating cylinder and the second rotating cylinder are driven by the pulley assembly; a second rotating rod rotatably connected to the mounting frame; a telescopic universal joint, with its two ends connected to the first rotating rod and the second rotating rod respectively; a third rotating rod rotatably connected to the mounting frame; and bevel gears, respectively connected to the second rotating rod and the third rotating rod, with the two bevel gears meshing with each other.

[0010] As a further preferred embodiment, the fertilizer application assembly includes: a connecting frame connected to the top of the ridging board; a storage bin connected to the connecting frame; a screw feeder installed on the storage bin, with the feed inlet of the screw feeder communicating with the storage bin; a hose connected to and communicating with the discharge outlet of the screw feeder; a discharge pipe connected to and communicating with the lower end of the hose; a connecting rod connected to the side of the discharge pipe; a telescopic frame connected to the ridging board, with the connecting rod sliding inside the telescopic frame; a guide frame connected to the ridging board; a telescopic frame slidably connected to the guide frame, with the connecting rod rotatably connected to the telescopic frame; a first spring connected to the upper and lower ends of the telescopic frame respectively; a material blocking mechanism located inside the storage bin for blocking fertilizer inside the storage bin; and a control mechanism located on the storage bin for controlling the operation of the material blocking mechanism.

[0011] As a further preferred embodiment, the material blocking mechanism includes: a baffle plate, rotatably connected to the inside of the storage box, and having a through hole; a sliding frame, slidably connected to the inside of the storage box, with the upper part of the sliding frame sliding within the through hole; and a connecting spring, with its two ends connected to the sliding frame and the storage box respectively.

[0012] As a further preferred embodiment, the control mechanism includes: an air pump installed on the side of one of the storage bins; a diverter pipe connected to and maintaining communication with the air outlet of the air pump, and the other two ends of the diverter pipe connected to and maintaining communication with the sides of the two storage bins respectively; an electric control valve installed on the diverter pipe; a slider slidably connected to one of the ridging plates; a second spring connected at both ends to the slider and the ridging plate respectively; a roller rotatably connected to the slider; and a photoelectric sensor installed on the slider.

[0013] As a further preferred embodiment, it also includes: a rotating frame rotatably connected to the ridging board; a second electric push rod rotatably mounted on the ridging board, with the telescopic rod of the second electric push rod rotatably connected to the rotating frame; a connecting cylinder disposed between the two rotating frames; a rotating roller rotatably connected to the rotating frame, with the rotating roller slidably connected to the connecting cylinder; and a drive motor mounted on one of the rotating frames, with the output shaft of the drive motor connected to one of the rotating rollers.

[0014] As a further preferred option, it also includes: a scale plate attached to the side of the storage bin.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention drives the ridging plates on the front and rear sides to move towards or away from each other through the first electric push rod. With the linkage of the telescopic universal shaft, telescopic square frame and guide frame, the ridge width can be infinitely adjusted. At the same time, the telescopic frame can drive the connecting rod and the discharge pipe to adjust the spacing synchronously. The hose adapts to deformation to ensure that the fertilization width always matches the ridge width. This design can solve the cumbersome problem of disassembling and replacing parts in traditional devices, significantly improve the efficiency and adaptability of operation, and is especially suitable for the agronomic needs of different crops such as potatoes and corn.

[0016] 2. This invention uses rollers, photoelectric sensors, and a controller to monitor the device's moving speed in real time, and controls the power of the air pump and the opening and closing of the electronic control valve in conjunction with them. This allows the baffle and sliding frame to dynamically adjust the amount of fertilizer falling, and works with the screw feeder to synchronize the fertilization rate with the moving speed. When the device is paused, the baffle mechanism will automatically close the outlet of the storage box, completely avoiding fertilizer accumulation or waste, ensuring uniform fertilization and reducing production costs.

[0017] 3. The rotary tillage component of the present invention achieves efficient power transmission through bevel gear and pulley assembly. After breaking up the soil, it is gathered into shape by ridging plate. The addition of rotating roller and connecting cylinder compacts and flattens the ridge surface under the drive of drive motor. This integrated design completes the entire soil treatment process in one go, greatly reducing the number of times the machine enters the field repeatedly, improving the quality of tillage and protecting the soil structure.

Detailed Implementation

[0032] Example: A ridging and fertilization device for farmland reclamation, such as... Figures 1-11As shown, the device includes a mounting frame 1, a connecting frame 2, a controller 201, a ridging plate 3, a first electric push rod 4, a rotary tillage component, and a fertilization component. The connecting frame 2 is connected to the left side of the mounting frame 1. The controller 201 is installed in the middle of the front side of the connecting frame 2. The ridging plate 3 is symmetrically slidably connected to the lower part of the mounting frame 1. The first electric push rod 4 is symmetrically installed in the lower part of the mounting frame 1. The first electric push rod 4 corresponds one-to-one with the ridging plate 3, and the telescopic rod of the first electric push rod 4 is connected to the upper part of its corresponding ridging plate 3. The ridging plate 3 is equipped with a rotary tillage component for loosening the soil and a fertilization component for fertilization.

[0033] like Figures 3-5 As shown, the rotary tillage assembly includes a first rotating cylinder 5, a second rotating cylinder 6, rotary tillage blades 7, and a rotating mechanism. The first rotating cylinder 5 is rotatably connected to the lower part of the front ridging plate 3, and the second rotating cylinder 6 is rotatably connected to the lower part of the rear ridging plate 3. The second rotating cylinder 6 is slidably connected to the first rotating cylinder 5. Rotary tillage blades 7 are spaced apart on the outer walls of both the first rotating cylinder 5 and the second rotating cylinder 6. The mounting frame 1 is equipped with a rotating mechanism for driving the first rotating cylinder 5 and the second rotating cylinder 6 to rotate. The rotating mechanism includes a first rotating rod 8, a pulley assembly 9, a second rotating rod 10, a telescopic universal joint 11, a third rotating rod 12, and a bevel gear 13. The upper part of each of the two ridging plates 3 is rotatably connected to a first rotating rod 8. The two first rotating rods 8 correspond one-to-one with the first rotating cylinder 5 and the second rotating cylinder 6, and the first rotating cylinder 5 and the second rotating cylinder 6 are respectively driven by the two first rotating rods 8 through the pulley assembly 9. The mounting frame 1 is rotatably connected to a second rotating rod 10. The front and rear ends of the second rotating rod 10 are respectively installed with telescopic universal shafts 11 between the ends of the two first rotating rods 8. The mounting frame 1 is rotatably connected to a third rotating rod 12. The right end of the third rotating rod 12 and the rear part of the second rotating rod 10 are both connected to bevel gears 13, and the two bevel gears 13 mesh with each other.

[0034] like Figures 6-11As shown, the fertilizer application assembly includes a connecting frame 14, a storage bin 15, a screw feeder 16, a hose 17, a discharge pipe 18, a connecting rod 19, a telescopic frame 20, a guide frame 21, a telescopic bracket 22, a first spring 23, a material blocking mechanism, and a control mechanism. The tops of both ridging plates 3 are connected to the connecting frame 14, and each connecting frame 14 contains a storage bin 15. A discharge port is located on the lower right side of each storage bin 15. A screw feeder 16 is installed at the bottom of each storage bin 15, and the inlet of the screw feeder 16 is connected to the outlet of the storage bin 15. Each screw feeder 16 has three discharge ports. Each discharge port is connected to a flexible hose 17 and kept in contact with the material. The bottom of each flexible hose 17 is connected to a discharge pipe 18 and kept in contact with the material. A connecting rod 19 is connected to the right side of each discharge pipe 18. A telescopic frame 20 is connected between the left sides of the two ridging plates 3, and each connecting rod 19 slides inside the telescopic frame 20. Guide frames 21 are connected to the left sides of the two ridging plates 3, and a telescopic frame 22 is slidably connected between the two guide frames 21. The connecting rod 19 is rotatably connected to the middle of the telescopic frame 22. A first spring 23 is connected between the upper and lower ends of the front and rear sides of the telescopic frame 22. The first spring 23 is located inside the guide frame 21. The storage bin 15 is equipped with a mechanism for storing... The storage bin 15 includes a material blocking mechanism to prevent fertilizer from entering. The storage bin 15 is equipped with a control mechanism to control the operation of the material blocking mechanism. The material blocking mechanism includes a baffle 24, a sliding frame 25, and a connecting spring 26. The baffle 24 is rotatably connected to the lower interior of both storage bins 15, and the baffle 24 has a through hole 2401. The sliding frame 25 is slidably connected to the lower interior of both storage bins 15, and the upper part of the sliding frame 25 slides within the through hole 2401. A connecting spring 26 connects the bottom of the sliding frame 25 to the bottom interior of the storage bin 15. The control mechanism includes an air pump 27, a diverter pipe 28, an electric control valve 29, a slider 30, and a second spring 31. The system includes a roller 32 and a photoelectric sensor 33. An air pump 27 is installed on the right side of the front storage bin 15. The air outlet of the air pump 27 is connected to a diverter pipe 28 and kept in communication. The diverter pipe 28 is a three-way pipe, and the other two ends of the diverter pipe 28 are connected to the lower parts of the two storage bins 15 respectively and kept in communication. The end of the diverter pipe 28 is located between the baffle 24 and the sliding frame 25. An electric control valve 29 is installed on the diverter pipe 28. A slider 30 is slidably connected to the lower right side of the front ridging plate 3. A second spring 31 is connected between the top of the slider 30 and the front ridging plate 3. A roller 32 is rotatably connected to the lower part of the slider 30. A photoelectric sensor 33 is installed on the upper part of the slider 30.

[0035] When the device is needed, it is first transported to the designated location. The second spring 31 ensures that the roller 32 is in contact with the soil. Then, the docking frame 2 is connected to the tractor, and the third rotating rod 12 is connected to the tractor's power source. Next, appropriate amounts of fertilizer are placed into the two storage bins 15. At this time, the baffle 24 blocks the fertilizer in the storage bins 15, and the sliding frame 25 blocks the discharge port (e.g., ...) in the storage bins 15. Figure 8(As shown); then the device is moved by a tractor, which simultaneously drives the third rotating rod 12 to rotate. The third rotating rod 12 drives the second rotating rod 10 to rotate via a bevel gear 13. The second rotating rod 10 drives the first rotating rod 8 to rotate via a telescopic universal joint 11. The first rotating rod 8 drives the first rotating cylinder 5, the second rotating cylinder 6, and the rotary tiller blades 7 to rotate via a pulley assembly 9. The rotary tiller blades 7 can turn over the soil, break up soil clods, and loosen the soil. At the same time, the ridging plate 3 can gather the loosened soil during the movement to automatically complete the ridging work. Meanwhile, the roller 32 can roll on the soil, and the photoelectric sensor 33 can detect the frequency of the grating change and monitor the data. Data is uploaded to controller 201. Controller 201 calculates the moving speed of the device and then controls the opening of the electronic control valve 29. Based on the moving speed, controller 201 controls the air pump 27 and screw feeder 16 to operate at a specified power. Air pump 27 draws in outside air and injects it into the space between baffle 24 and sliding frame 25 through diversion pipe 28, increasing the air pressure inside the space. This air pressure pushes the sliding frame 25 downwards, compressing the connecting spring 26 and preventing the sliding frame 25 from blocking the discharge port in storage bin 15. Furthermore, the sliding frame 25 pulls the baffle 24 downwards through through hole 2401, preventing the baffle 24 from obstructing the flow. The fertilizer inside the storage bin 15 will fall onto the sliding frame 25 due to gravity, and move along the airflow blown out by the diversion pipe 28 to the screw feeder 16. The screw feeder 16 can evenly deliver the fertilizer into each hose 17, and the airflow blown out by the diversion pipe 28 will spray downward through the hose 17 and the discharge pipe 18 in sequence, thereby driving the fertilizer inside the hose 17 downward through the discharge pipe 18 and falling into the soil, completing the automatic fertilization work; when the moving speed of the device changes, the rotation speed of the roller 32 will also change accordingly, so that the controller 201 can adjust the power of the air pump 27 to achieve the effect of controlling the fertilization rate (i.e., the air pump 27 and the screw feeder 16 can evenly deliver the fertilizer into each hose 17, and the airflow blown out by the diversion pipe 28 will spray downward through the hose 17 and the discharge pipe 18 in sequence, thereby driving the fertilizer inside the hose 17 downward through the discharge pipe 18 and falling into the soil, completing the automatic fertilization work; when the moving speed of the device changes, the rotation speed of the roller 32 will also change accordingly, so that the controller 201 can adjust the power of the air pump 27 to change, thereby achieving the effect of controlling the fertilization rate (i.e., the air pump 27 and the screw feeder 16 can evenly deliver the fertilizer into each hose 17, and the airflow blows downward through the hose 17 and the discharge pipe 18 in sequence). The higher the power of the feeder 16, the greater the air volume of the air pump 27, and the more fertilizer is delivered to each hose 17 by the screw feeder 16 per unit time, thus increasing the fertilization rate. When the device stops moving, the roller 32 stops rotating, the controller 201 controls the electric control valve 29 to close, and controls the air pump 27 and screw feeder 16 to stop working. At this time, the connecting spring 26 will return to its original state, driving the sliding frame 25 to move upward and reset, so that the sliding frame 25 blocks the discharge port in the storage box 15 again. The sliding frame 25 will also push the baffle 24 to rotate upward through the through hole 2401, so that the baffle 24 blocks the fertilizer inside the storage box 15 again, thereby stopping fertilization and preventing local over-fertilization.When the ridge width needs to be adjusted, the controller 201 can control the first electric push rod 4 to drive the ridge plates 3 on both sides to move towards each other or away from each other, thereby adjusting the distance between the two ridge plates 3 and achieving the purpose of adjusting the ridge width. When the ridge plates 3 on both sides move towards each other or away from each other, the ridge plates 3 will drive the first rotating cylinder 5 and the second rotating cylinder 6 to move towards each other or away from each other, so as to change the distribution length of the rotary tiller blades 7. This allows the rotary tiller blades 7 to adapt to different ridge widths for rotary tillage. At the same time, the ridge plates 3 will drive the first rotating rods 8 on both sides to move towards each other or away from each other, so as to change the distance between the first rotating rod 8 and the second rotating rod 10. At this time, the telescopic universal joint 11 can adapt to rotate and extend, so that the second rotating rod 10 always remains in the same position when rotating. The telescopic universal joint 11 drives the first rotating rod 8 to rotate. Simultaneously, the telescopic frame 20 adapts to the movement of the two ridging plates 3, and the ridging plates 3 drive the guide frames 21 on both sides to move towards or away from each other. The guide frames 21 drive the telescopic frame 22 to adapt, meaning the upper and lower ends of the telescopic frame 22 move towards or away from the connecting rod 19. The first spring 23 adapts to this, and the telescopic frame 22 drives the two adjacent connecting rods 19 to move towards or away from each other, thereby driving the two adjacent discharge pipes 18 to move towards or away from each other, adjusting the distance between the two adjacent discharge pipes 18, and thus adjusting the fertilization width of the device. The flexible hose 17 adapts to the terrain changes to accommodate different ridging widths for fertilization.

[0036] like Figure 12 and Figure 13 As shown, it also includes a rotating frame 34, a second electric push rod 35, a connecting cylinder 36, a rotating roller 37, and a drive motor 38. The top of each of the two ridging plates 3 is rotatably connected to the rotating frame 34, and the right side of each of the two ridging plates 3 is rotatably connected to the second electric push rod 35. The telescopic rod of the second electric push rod 35 is rotatably connected to the upper part of the rotating frame 34. A connecting cylinder 36 is provided between the lower parts of the two rotating frames 34. The front and rear sides of the connecting cylinder 36 are slidably connected to the rotating roller 37, and the two rotating rollers 37 are rotatably connected to the lower parts of the two rotating frames 34 respectively. The front lower part of the front rotating frame 34 is equipped with a drive motor 38, and the output shaft of the drive motor 38 is connected to the front rotating roller 37.

[0037] During the ridging and fertilization process, the device can control the second electric push rod 35 via controller 201 to drive the rotating frame 34 to rotate downwards. The rotating frame 34 can drive the connecting cylinder 36 and the rotating roller 37 to move downwards, so that the connecting cylinder 36 and the rotating roller 37 come into contact with the ridged soil. The controller 201 can also control the drive motor 38 to drive the connecting cylinder 36 and the rotating roller 37 to rotate, so that the connecting cylinder 36 and the rotating roller 37 can roll along the ridged soil, thereby leveling and compacting the ridged soil. When the device is not in use, the drive motor 38 can be stopped via controller 201. The operation stops the connecting cylinder 36 and the rotating roller 37, and controls the second electric push rod 35 to drive the rotating frame 34 to rotate upward and reset. The rotating frame 34 can drive the connecting cylinder 36 and the rotating roller 37 to rotate upward and reset, so that the connecting cylinder 36 and the rotating roller 37 are separated from the soil. When the ridging plates 3 on the front and rear sides move towards each other or away from each other, the ridging plates 3 can drive the rotating frames 34 and the rotating roller 37 on the front and rear sides to move towards each other or away from each other, thereby adjusting the overall length of the connecting cylinder 36 and the rotating roller 37 to adapt to the leveling and compaction of the connecting cylinder 36 and the rotating roller 37.

[0038] like Figure 1 As shown, it also includes a scale plate 39. The left side of each of the two storage bins 15 is connected to the scale plate 39, and the scale plate 39 is made of transparent material. By observing the scale on the scale plate 39, the remaining amount of fertilizer inside the storage bin 15 can be known, which makes it convenient to replenish the fertilizer inside the storage bin 15 in a timely manner.
