Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a precision fertilizer applicator for a seeder. Background Technology

[0002] A seeder fertilizer applicator is a specialized device installed on a seeder. It achieves synchronous and precise application of fertilizer and seeds through a mechanical or electronic control system. Its core function is to control the amount of fertilizer applied according to preset parameters, so as to distribute the fertilizer evenly near the seeds or in a specific soil layer, thus realizing integrated seed and fertilizer operation. This equipment can improve fertilizer utilization, reduce waste, and promote crop root absorption by adjusting the depth and position of fertilizer application. It has the functions of improving agricultural production efficiency, reducing labor costs and reducing environmental pollution, and is an important technical equipment for precision planting in modern agriculture.

[0003] When using existing seeders for fertilization, the traditional fertilizer storage structure requires manual pre-loading of fertilizer. In large-scale field operations, the large weight of the fertilizer packaging unit (usually 25-50kg) and the frequent manual loading and unloading operations can easily cause muscle strain for the operator, and the machine is not very practical. At the same time, the inability to accurately weigh the fertilizer during sowing and fertilization can lead to over-fertilization, causing seedling burn or fertilizer loss.

[0004] Therefore, a precision fertilizer applicator for seeders is needed to improve the above problems. Utility Model Content

[0005] To address the problem that frequent manual loading and unloading operations during fertilization with precision fertilizer applicators on seeders easily cause muscle strain for operators and result in poor practicality, this utility model provides a precision fertilizer applicator for seeders to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A precision fertilizer applicator for a seeder includes a mounting bracket, a fertilizer storage shell disposed on the outer wall of the mounting bracket, a lifting component mounted on one side of the fertilizer storage shell and on the outer wall of the mounting bracket, a material guide groove sequentially opened from left to right on the inner wall of the fertilizer storage shell, a precision component disposed on the bottom outer wall of the fertilizer storage shell, and a sieve plate mounted on the inner wall of the fertilizer storage shell.

[0008] The lifting assembly includes a lifting guide rail, which is mounted on the outer wall of the mounting bracket. A lifting bracket is slidably connected to the inner wall of the lifting guide rail. A threaded rod is mounted on the opposite inner wall of the lifting bracket. One end of the threaded rod passes through the lifting bracket and extends to the outer wall of the lifting bracket, where a drive motor is mounted. A lifting plate is threadedly connected to the outer wall of the threaded rod. A limiting slide rod is slidably connected to the outer wall of the lifting plate, wherein the limiting slide rod is mounted on the opposite inner wall of the lifting bracket. An extension plate is slidably connected to the bottom outer wall of the lifting plate via a slider.

[0009] As a preferred embodiment of this utility model, a movable support wheel is installed on the bottom outer wall of the extension plate, a limit bolt is threadedly connected to the outer wall of the lifting guide rail, one end of the limit bolt is attached to the outer wall of the lifting bracket, and a control panel is installed on the outer wall of the lifting guide rail.

[0010] As a preferred embodiment of this utility model, the precision assembly includes a precision housing, and multiple precision housings are provided and respectively located on the bottom outer wall of the fertilizer storage housing. The precision housing is located directly below the feed trough, and fixed brackets are installed on the opposite outer walls of the precision housing. Rotating rods are installed on the opposite outer walls of the fixed brackets.

[0011] As a preferred embodiment of this utility model, one end of the rotating rod passes through the fixed bracket and extends to the outer wall of the fixed bracket where a servo motor is installed. An array of baffles is arranged on the outer wall of the rotating rod, wherein the baffles are located directly below the guide groove, and an infrared ranging sensor is arranged on one side of the baffles and on the outer wall of the fixed bracket.

[0012] As a preferred embodiment of this utility model, a vibrator is installed on the side wall of the precision measuring housing, a guide tube is installed on the side wall of the precision measuring housing, and a limit slide rail is symmetrically arranged on one side of the guide tube and on the inner wall of the precision measuring housing.

[0013] As a preferred embodiment of this utility model, a sliding baffle is slidably connected to the outer wall of the limiting slide rail, wherein the sliding baffle is located on one side of the guide tube, and an electric control cylinder is installed on one side of the sliding baffle and on the inner wall of the precision housing, wherein one end of the electric control cylinder is connected to the sliding baffle, and a precision sensor is provided on the outer wall of the sliding baffle.

[0014] As a preferred embodiment of this utility model, a connecting bracket is installed on one side of the lifting component and on the outer wall of the mounting bracket. A fixing block is installed on the opposite side wall of the connecting bracket. A rotating rod is rotatably connected to the outer wall of the fixing block. A universal wheel is installed at one end of the rotating rod. A connector is installed at one end of the connecting bracket. A movable wheel is rotatably connected to the opposite side wall of the mounting bracket.

[0015] As a preferred embodiment of this utility model, the control panel is connected to a drive motor, a servo motor, an infrared ranging sensor, a vibrator, an electric cylinder, and a precision sensor via wires, and the connection method is electrical connection. The screen plate is provided in two sets and is located on the inner wall opposite to each other of the fertilizer storage shell. The material guide trough is provided in multiple sets and the material guide troughs are symmetrical in structure.

[0016] Compared with existing technologies, this utility model can lift fertilizer by setting a lifting component in the precision fertilizer applicator of the seeder. The control panel controls the operation of the drive motor. When the drive motor rotates, the drive shaft of the drive motor drives the threaded rod to rotate, so that the threaded rod drives the lifting plate through the threaded connection. The lifting plate is subjected to force on the outer wall of the limit slide rod and moves upward, thereby moving the lifting plate to the upper end of the lifting bracket. When the fertilizer is located on one side of the fertilizer storage shell, the fertilizer can be guided and poured into the inner cavity of the fertilizer storage shell. This solves the problem that frequent manual repetitive loading and unloading operations can easily cause muscle strain to the operator and has poor practicality.

[0017] This invention enables precision fertilization by incorporating a precision fertilizer applicator into the seeder. After the fertilizer is manually weighed and loaded into the precision housing, the control panel activates a vibrator to flatten the fertilizer layer. Simultaneously, an infrared ranging sensor and a precision sensor collect data on the fertilizer layer height and contact points, feeding back electrical signals to the control panel for storage. The control panel then activates an electric cylinder to pull a sliding baffle upwards along a limit rail for fertilization. Subsequently, the control panel drives a servo motor to rotate a rotating rod and a baffle plate. The fertilizer in the storage housing flows into the precision housing via a guide trough until it contacts the precision sensor, triggering the set parameters. The servo motor then stops, completing the quantitative fertilizer supply. After the vibrator is restarted to flatten the fertilizer, the infrared sensor detects the fertilizer layer height a second time. Once the set parameters are reached, the control panel activates an electric cylinder to pull the sliding baffle upwards along the limit rail, ultimately completing precise fertilization through a guide tube. This solves the problem of inaccurate fertilizer weighing during sowing, which can lead to excessive fertilizer application causing seedling burn or fertilizer loss. Attached Figure Description

[0027] In this embodiment, specific references Figure 1 , Figure 2 , Figure 4 and Figure 5 The precision assembly 5 includes a precision housing 501. Multiple precision housings 501 are arranged on the bottom outer wall of the fertilizer storage housing 2. The precision housings 501 are located directly below the material guide trough 4. Fixed supports 502 are mounted on opposite outer walls of the precision housings 501. Rotating rods 503 are mounted on opposite outer walls of the fixed supports 502.

Baffle plates 505 are arranged in an array on the outer wall of the rotating rods 503, with the baffle plates 505 located directly below the material guide trough 4 and one side of the baffle plates 505 located on the outer wall of the fixed supports 502. An infrared ranging sensor 506 is installed on the top. A vibrator 507 is installed on the side wall of the precision housing 501. A guide tube 508 is installed on the side wall of the precision housing 501. A limit slide rail 509 is symmetrically arranged on one side of the guide tube 508 and on the inner wall of the precision housing 501. A sliding baffle 510 is slidably connected to the outer wall of the limit slide rail 509. The sliding baffle 510 is located on one side of the guide tube 508.

One end of the electric cylinder 511 is connected to the sliding baffle 510. A precision sensor 512 is installed on the outer wall of the sliding baffle 510.

[0028] A connecting bracket 7 is installed on one side of the lifting component 3 and on the outer wall of the mounting bracket 1. A fixing block 8 is installed on the opposite side wall of the connecting bracket 7. A rotating rod 9 is rotatably connected to the outer wall of the fixing block 8. A universal wheel 10 is installed at one end of the rotating rod 9. A connector 11 is installed at one end of the connecting bracket 7. A movable wheel 12 is rotatably connected to the opposite side wall of the mounting bracket 1. The control panel 310 is electrically connected to the drive motor 304, servo motor 504, infrared ranging sensor 506, vibrator 507, electric cylinder 511 and precision sensor 512. The device is powered on, and the control panel 310 controls the drive motor 304, servo motor 504, infrared ranging sensor 506, vibrator 507, electric cylinder 511 and precision sensor 512 to operate. Two sets of screen plates 6 are provided and are located on the opposite inner walls of the fertilizer storage shell 2. Multiple sets of guide troughs 4 are provided and the guide troughs 4 are symmetrical.

[0029] Based on the above structural features and connection relationships, when the lifting component 3 is used for sowing and fertilization, it is only necessary to tighten the limiting bolt 309 to loosen the fixing of the limiting bolt 309 to the lifting bracket 302, then lift the lifting bracket 302 so that the lifting bracket 302 moves upward on the inner wall of the lifting guide rail 301, so that the lifting bracket 302 is away from the ground, and then tighten the limiting bolt 309 to fix the lifting bracket 302, so that the lifting component 3 will not cause interference when the device is sowing and fertilizing.

[0030] When the precision fertilizer applicator of this seeder is working, the extension plate 307 is pulled, which in turn slides laterally on the outer wall of the lifting plate 305 via a slider, so that the extension plate 307 moves out of the lifting plate 305. Then, fertilizer is placed on the outer walls of the lifting plate 305 and the extension plate 307. The switch of the control panel 310 is turned on, so that the control panel 310 controls the drive motor 304 to operate. When the drive motor 304 rotates, the drive shaft of the drive motor 304 drives the threaded rod 303 to rotate, so that the threaded rod 303 drives the lifting plate 305 through the threaded connection. The lifting plate 305 is subjected to force and moves upward on the outer wall of the limiting slide rod 306, which in turn moves the lifting plate 305 to move the fertilizer to the upper end of the lifting bracket 302. When the fertilizer is on one side of the fertilizer storage shell 2, the fertilizer can be guided and poured into the inner cavity of the fertilizer storage shell 2, thus solving the problem that frequent manual loading and unloading operations are prone to causing muscle strain for the operator and have poor practicality.

[0031] After weighing the fertilizer, the weighed fertilizer is placed into the inner cavity of the precision housing 501. Then, the switch of the control panel 310 is turned on, so that the control panel 310 controls the vibrator 507 to vibrate, so that the vibrator 507 vibrates the precision housing 501, so that the fertilizer in the inner cavity of the precision housing 501 is flattened. At this time, the infrared distance sensor 506 generates data on the surface distance of the fertilizer, so that the infrared distance sensor 506 generates an electrical signal that is transmitted to the control panel 310 through the wire. At the same time, when the precision sensor 512 comes into contact with the fertilizer, it generates data, so that the precision sensor 512 generates an electrical signal that is transmitted to the control panel 310 through the wire, so that the control panel 310 stores the parameters of the fertilizer.

[0032] The control panel 310 controls the servo motor 504 to operate, which in turn drives the rotating rod 503 to rotate. This rotating rod 503 then rotates the baffle plate 505. When the baffle plate 505 is directly below the guide chute 4, it blocks the chute. Conversely, when the baffle plate 505 moves to one side, the fertilizer in the storage housing 2 flows through the guide chute 4 into the precision housing 501. When the fertilizer comes into contact with the precision sensor 512, the sensor generates an electrical signal, which is transmitted to the control panel 310 via wires. When the set parameters are reached, the servo motor 504 stops, and the control panel 310 then controls the vibrator 507 to vibrate. The vibrator 507 vibrates the precision housing 501 to flatten the fertilizer inside the precision housing 501. At this time, the infrared distance sensor 506 generates data on the distance to the surface of the fertilizer, and the infrared distance sensor 506 generates an electrical signal that is transmitted to the control panel 310 through a wire. When the set parameters are reached, the control panel 310 controls the electric cylinder 511 to operate, so that one end of the electric cylinder 511 applies a pulling force to the sliding baffle 510, so that the sliding baffle 510 moves upward on the limit slide rail 509, thereby allowing the fertilizer inside the precision housing 501 to be applied through the guide pipe 508. This solves the problem of inaccurate fertilizer weighing during sowing and fertilization, which can lead to excessive fertilizer causing seedling burn or fertilizer loss.

[0033] 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.
