Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve assembly technology, specifically a hydraulic valve assembly for a seeding machine. Background Technology

[0002] A seed broadcaster, also known as a fertilizer spreader, is an agricultural machine used for spreading seeds on the ground or from the air. Based on power source, it can be divided into human-powered, animal-powered, and machine-powered types. Based on working principle, it can be divided into centrifugal and drop-type seed broadcasters. A centrifugal seed broadcaster consists of a seed box, a high-speed rotating spreading disc, and a drive unit; the spreading disc rotates at 500-1000 rpm. A drop-type seed broadcaster consists of a seed box, a seed brush wheel, and an inclined plate, with a spreading width of approximately 3-5 meters.

[0003] In the use of existing seeders, users often cannot control the seeding distance and amount. When users need to seed certain types of seeds with specific seeding requirements, they need to pause for a period of time to increase the seeding amount. When users need to seed seeds over long distances, they need to frequently move the seeder to achieve this, thus reducing the practicality of the seeder and making it inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hydraulic valve group for a seeding machine, which solves the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic valve assembly for a seeding machine, comprising a mounting plate and multiple delivery pipes. The hydraulic valve assembly is mounted on the seeding machine via the mounting plate. The mounting plate is equipped with a tank assembly, a hydraulic regulating valve, and an adjusting assembly. The inlet of the hydraulic regulating valve is connected to the tank assembly via delivery pipes, and the outlet of the hydraulic regulating valve is connected to the adjusting assembly via delivery pipes. The outlet of the adjusting assembly is connected to a delivery pipe, on which a one-way valve is connected. The one-way valve is connected to the tank assembly via the delivery pipe. The adjusting assembly includes a hydraulic motor, and the hydraulic regulating valve controls the rotational speed of the hydraulic motor. A seeding assembly is mounted on the hydraulic motor, and a movable plate is provided on the top of the seeding assembly. The movable plate on the top of the seeding assembly allows the hydraulic valve assembly to adjust the amount of seeds seeded by the seeding machine, improving the operability of the hydraulic valve assembly.

[0006] Furthermore, the spreading assembly includes a rotating shaft. Multiple hooks are fixedly mounted on the end of the rotating shaft furthest from the hydraulic motor. A rectangular groove is formed within each hook. Multiple telescopic shafts and an electric actuator are mounted at the bottom of the rectangular groove on each hook. The telescopic ends of the electric actuator and the telescopic shafts are fixedly mounted on the bottom of a movable plate. This fixed mounting of the electric actuator and the telescopic shafts on the bottom of the movable plate allows the electric actuator to move along with the movable plate, improving the overall integrity of the internal structure of the hydraulic valve group of the spreading machine.

[0007] Furthermore, the adjustment assembly also includes a hollow tank fixedly mounted on the seeder. A controller is fixedly mounted on one side of the hollow tank, and a discharge port is opened at the lower end of the side of the hollow tank away from the controller. The electric actuator is remotely connected to the controller. This remote connection between the electric actuator and the controller allows the controller to directly control the extension and retraction of the electric actuator remotely, improving the intelligence of the hydraulic valve group operation of the seeder.

[0008] Furthermore, the tank assembly includes an oil pipe wall mounted on a mounting plate, with an oil outlet on one side of the oil pipe wall and an oil inlet on the top side of the oil pipe wall near the oil outlet. The oil outlet is connected to one side of the hydraulic regulating valve via a delivery pipe, and an oil filling port is provided on the top of the oil pipe wall. A sealing assembly is provided on the side of the oil filling port on the oil pipe wall.

[0009] Furthermore, the sealing assembly includes a fixing body fixed to the top of the oil pipe wall, a shaft fixedly mounted on the fixing body, a flip plate rotatably disposed at the center of the shaft, and a fixed shaft movably disposed at the end of the flip plate away from the shaft, the fixed shaft being used to fix the flip plate to the top of the oil pipe wall.

[0010] Furthermore, the hydraulic regulating valve has a flow channel, within which a piston is movable. An adjusting ring is fixedly mounted on the top of the piston and threadedly connected to the top of the hydraulic regulating valve. The adjusting ring is used to adjust the position of the piston. This adjustment allows the user to regulate the flow rate and volume of hydraulic oil entering the hydraulic motor, thus improving the adjustability of the hydraulic valve assembly used in the seeder.

[0011] Furthermore, a baffle is fixedly installed on the side of the hollow tank away from the controller. The baffle is located at the upper end of the discharge port and is used to prevent seeds from splashing upwards. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention regulates the flow rate and volume of hydraulic oil entering the hydraulic motor by adjusting the hydraulic regulating valve, thereby adjusting the speed of the hydraulic motor. The rapidly rotating hydraulic motor can spread seeds over a wide area through the sowing component, while the controller can control the extension and retraction of the electric push rod. The extended movable plate can increase the sowing amount of seeds by the sowing component, thus improving the practicality of the hydraulic valve group of the sowing machine.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0016] Example The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A hydraulic valve assembly for a seeding machine includes a mounting plate 2 and multiple delivery pipes 6. The hydraulic valve assembly is mounted on the seeding machine via the mounting plate 2. A tank assembly 1, a hydraulic regulating valve 3, and a regulating assembly 4 are mounted on the mounting plate 2. The inlet of the hydraulic regulating valve 3 is connected to the tank assembly 1 via the delivery pipes 6, and the outlet of the hydraulic regulating valve 3 is connected to the regulating assembly 4 via the delivery pipes 6. The outlet of the regulating assembly 4 is connected to the delivery pipe 6, and a one-way valve 5 is connected to the delivery pipe 6. The one-way valve 5 is connected to the tank assembly 1 via the delivery pipe 6. The regulating assembly 4 includes a hydraulic motor 43. The hydraulic regulating valve 3 controls the rotational speed of the hydraulic motor 43. A spreading assembly 44 is installed on the hydraulic motor 43. A movable plate 442 is provided on the top of the spreading assembly 44. The spreading assembly 44 includes a rotating shaft 441. Multiple hooks 445 are fixedly installed at the end of the rotating shaft 441 away from the hydraulic motor 43. A rectangular groove is formed inside each hook 445. Multiple telescopic shafts 443 and an electric actuator 444 are installed at the bottom of the rectangular groove of each hook 445. The telescopic ends of the electric actuator 444 and the telescopic shafts 443 are fixedly installed at the bottom of the movable plate 442. The adjusting assembly 4 also includes a hollow tank 46 fixedly installed on the spreading machine. A controller 45 is fixedly installed on one side of the hollow tank 46. The hollow tank 46 is located away from the controller 45. A discharge port 42 is provided at the lower end of one side of the tank 5. The electric actuator 444 is remotely connected to the controller 45. The tank assembly 1 includes an oil pipe wall 11 mounted on the mounting plate 2. An oil outlet 12 is provided on one side of the oil pipe wall 11. An oil inlet 14 is provided on the top of the oil pipe wall 11 near the oil outlet 12. The oil outlet 12 is connected to one side of the hydraulic regulating valve 3 through a conveying pipe 6. An oil filling port 13 is provided on the top of the oil pipe wall 11. A sealing assembly 15 is provided on the side of the oil filling port 13 of the oil pipe wall 11. The sealing assembly 15 includes a fixing body 153 fixed to the top of the oil pipe wall 11. A shaft 154 is fixedly installed on the fixing body 153. A rotating tilting plate 151 is provided at the center position. A fixed shaft 152 is movably provided at the end of the tilting plate 151 away from the shaft 154. The fixed shaft 152 is used to fix the tilting plate 151 to the top of the oil pipe wall 11. A flow channel is opened in the hydraulic regulating valve 3. A piston is movably provided in the hydraulic regulating valve 3 within the flow channel. An adjusting ring is fixedly installed on the top of the piston. The adjusting ring is threadedly connected to the top of the hydraulic regulating valve 3. The adjusting ring is used to adjust the position of the piston. A baffle 41 is fixedly installed on the side of the hollow tank 46 away from the controller 45. The baffle 41 is located at the upper end of the discharge port 42. The baffle 41 is used to prevent seeds from splashing upwards.

[0017] The working principle of the controller 45 can be divided into four basic steps: input, processing, output, and feedback. First, the controller 45 receives input signals from external devices or users, such as button presses or sensor detection information. Next, the controller 45 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices. Since the controller 45 and the electric push rod 444 are equipped with Bluetooth modules, the controller 45 can remotely control the extension and retraction of the electric push rod 444. When the electric push rod 444 extends, the telescopic shaft 443 will also push the movable plate 442 upward, so that the movable plate 442, together with the hook body 445, increases the sowing area of ​​the seed spreading component 44, thereby increasing the sowing amount of the seeder.

[0018] The hydraulic regulating valve 3, by adjusting the regulating ring above it, regulates the flow rate and volume of hydraulic oil entering the hydraulic motor 43. The check valve 5 is a valve that allows only unidirectional fluid flow, mainly divided into ordinary check valves and hydraulically controlled check valves. They are widely used in pneumatic and hydraulic systems to control the flow direction and prevent backflow. Common check valve types include inline spring-assisted check valves and inline ball check valves, typically installed at the end of the pump's suction line to ensure unidirectional fluid flow and prevent hydraulic oil backflow. Since the hydraulic regulating valve 3, check valve 5, hydraulic motor 43, and controller 45 within the hydraulic valve group of the seeder are all common existing technologies, this utility model does not elaborate on them.

[0019] Among them, the hydraulic motor 43 is an actuator in a hydraulic system that converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy torque and speed of its output shaft. Liquid is the medium for transmitting force and motion.

[0020] Because a baffle 41 is provided above the discharge port 42, the sowing component 44 can effectively prevent seeds from splashing upwards when sowing seeds, thus avoiding harm to the human body from upward-splashing seeds and improving the practicality of the hydraulic valve group of the sowing machine.

[0021] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the hydraulic valve assembly of the seeder are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. During use, the user can directly control the flow rate and volume of hydraulic oil entering the hydraulic motor 43 by adjusting the hydraulic regulating valve 3. This allows the hydraulic regulating valve 3 to directly adjust the rotation speed of the hydraulic motor 43. When the rotation speed of the hydraulic motor 43 increases, the rotation of the seeding component 44 also increases, thus improving the spreading speed. The seeder controls the seed sowing distance and range. When the user needs to adjust the seed sowing amount, they only need to adjust the electric push rod 444 through the controller 45, causing the electric push rod 444 to extend upward with the movable plate 442. This increases the contact area between the sowing component 44 and the seeds, thereby increasing the sowing amount. Through the cooperation of the above structure, the hydraulic valve group of the seeder can adjust the seed sowing range by adjusting the hydraulic regulating valve, and the extended movable plate can increase the sowing amount of the seeding component, thus improving the practicality of the hydraulic valve group of the seeder.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
