Description

Technical Field

[0001] The present application relates to the field of agricultural seeding machines, and in particular to a seeding machine with a hydraulic energy-saving component. Background Art

[0002] A seeding machine is a common agricultural machine that replaces manual labor to evenly sow seeds into the soil. Its popularization and application are manifestations of agricultural mechanization. Most seeding machines are designed with two sets of wheel groups. One set is the traveling wheels of the seeding machine, and the other set is the seeding wheels of the seeding machine. The traveling wheels are no different from common wheels and are of a common tire structure for the movement of the seeding machine. The seeding wheels are relatively special and are composed of a metal disk surface as a whole. During the towing process before seeding, the seeding wheel group is lifted, and only the traveling wheels are in contact with the ground. During seeding, since the rubber tire structure of the traveling wheels is not suitable for contacting soft soil, the traveling wheels are lifted, and the seeding wheels are changed to be in contact with the ground. The seeding wheels contact the ground, drive the seeding machine forward, and at the same time sow the seeds onto the ground.

[0003] The lifting and lowering process of the above-mentioned traveling wheel group or seeding wheel group relies on a hydraulic system, that is, an oil cylinder is provided for each traveling wheel or each group of seeding wheels, and the lifting and lowering of the traveling wheel group is realized by the extension and retraction of the piston rod of the oil cylinder. Although the principle is simple, it consumes a lot of energy. Summary of the Invention

[0004] In order to reduce the energy consumption of the seeding machine wheel group during lifting and lowering, the present application provides a seeding machine with a hydraulic energy-saving component.

[0005] A seeding machine with a hydraulic energy-saving component provided by the present application adopts the following technical solutions:

[0006] A seeding machine with a hydraulic energy-saving component includes a frame. On both sides of the bottom end of the frame, there is a row of traveling wheels, and further includes:

[0007] A wheel frame, one end of which is hinged to the frame and the other end is hinged to the axle of the traveling wheel for lifting and lowering the traveling wheel;

[0008] A first oil cylinder, the top end of the cylinder body is hinged to the frame, and the end of the piston rod is hinged to the wheel frame to drive the wheel frame to lift and lower;

[0009] A second oil cylinder, the top end of the cylinder body is hinged to the frame, and the end of the piston rod is hinged to the other wheel frame to drive the wheel frame to lift and lower;

[0010] A hydraulic station is arranged on the part of the frame between the first oil cylinder and the second oil cylinder; the first oil cylinder, the second oil cylinder, and the frame are connected by hydraulic pipes, and the oil outlet of the first oil cylinder is connected to the oil inlet of the second oil cylinder.

[0011] By adopting the above technical solution, the frame is the main structure of the seeder, and the hinged structure of the wheel frame provides the structural basis for the lifting of the walking wheels. The first oil cylinder and the second oil cylinder respectively correspond to the two walking wheels and drive the two walking wheels to lift;

[0012] In the above solution, the oil outlet of the first oil cylinder is connected to the oil inlet of the second oil cylinder, and then the first oil cylinder and the second oil cylinder are connected to the hydraulic station, thereby forming a hydraulic cycle, combining the two sets of hydraulic cycles in the traditional solution into one to achieve energy conservation;

[0013] The oil outlet of the first oil cylinder is connected to the second oil cylinder, and the discharged hydraulic oil is transported to the second oil cylinder to push the piston rod of the second oil cylinder. Only one oil pump is required to control the two sets of hydraulic systems, combining the two sets of hydraulic cycles into one by connecting the two oil cylinders;

[0014] The hydraulic station is a common control component of the hydraulic system, used to control the oil pump and oil tank of the hydraulic system. The oil tank is used to store hydraulic oil, and the oil pump is used to transport hydraulic oil.

[0015] Optionally, the volume of the first oil cylinder is larger than that of the second oil cylinder.

[0016] By adopting the above technical solution, considering that the oil outlet of the oil cylinder is opened at one end close to the piston rod, and the oil inlet is arranged at one end far from the piston rod, most of the space is occupied by the piston rod near the oil outlet. If the volumes of the two oil cylinders are the same, when the piston rods extend the same length, the oil output of one oil cylinder cannot balance the oil input of the other oil cylinder. Therefore, it is necessary to increase the volume of the first oil cylinder to expand the volume between the inner wall of the oil cylinder and the piston rod of the oil cylinder;

[0017] In practical applications, it is recommended to select an oil cylinder model with a larger diameter and the same length as the first oil cylinder.

[0018] Optionally, the oil outlet of the first oil cylinder is connected to the hydraulic station.

[0019] By adopting the above technical solution, the oil outlet of the first oil cylinder is connected to the hydraulic station in addition to the oil inlet of the second oil cylinder. The hydraulic station is the control area of the hydraulic system, and an oil pump and an oil tank are arranged inside it, which can provide supplementary hydraulic oil when the transportation of hydraulic oil is unstable;

[0020] Therefore, in practical applications, a compensation control device also needs to be set in the hydraulic station.

[0021] Optionally, a hydraulic oil pump is arranged between the oil outlet of the first oil cylinder and the oil inlet of the second oil cylinder.

[0022] By adopting the above technical solution, the hydraulic oil pump is in a normally closed state. When the hydraulic oil is transported stably, it can be transported only by the oil pump in the hydraulic station. When the hydraulic oil circulation in the hydraulic system is unstable, the oil pump serves as an auxiliary component to provide the transportation force between the first oil cylinder and the second oil cylinder.

[0023] Optionally, the hydraulic station is connected to the oil inlet of the first oil cylinder and the oil outlet of the second oil cylinder.

[0024] By adopting the above technical solution, the hydraulic station is connected to the oil inlet of the first oil cylinder and the oil outlet of the second oil cylinder to form a cycle of hydraulic oil circulation and transportation. Thus, the hydraulic oil in the oil pump enters the oil inlet of the first oil cylinder, the original hydraulic oil in the first oil cylinder is transported to the second oil cylinder, and the oil in the second oil cylinder is transported to the oil tank of the hydraulic station to complete the hydraulic oil circulation.

[0025] Optionally, a detection meter is arranged between the oil outlet of the first oil cylinder and the oil inlet of the second oil cylinder for detecting the hydraulic oil flow rate.

[0026] By adopting the above technical solution, the user can directly observe the flow rate of the hydraulic oil transported between the first oil cylinder and the second oil cylinder through the detection meter.

[0027] Optionally, a detection meter is arranged between the hydraulic station and the oil inlet of the second oil cylinder for detecting the hydraulic oil flow rate.

[0028] By adopting the above technical solution, the user can directly compensate the amount from the oil cylinder of the hydraulic station to the second oil cylinder through the detection meter.

[0029] Optionally, a stabilizing frame is connected between the first oil cylinder and the second oil cylinder, and the stabilizing frame connects the first oil cylinder and the second oil cylinder into a whole.

[0030] By adopting the above technical solution, the stabilizing frame ensures that the angular changes of the first oil cylinder and the second oil cylinder are consistent, that is, the wheels are lifted and lowered synchronously. Description of the Drawings

[0034] The following is combined with the attached Figure 1-2A further detailed description of the present application is provided.

[0035] An embodiment of the present application discloses a seeder with a hydraulic energy-saving component. Referring to Figure 1 , a seeder with a hydraulic energy-saving component includes a frame 1. The frame 1 is the main structure of the seeder body. A wheel frame 22 is hinged to the bottom of the frame 1. One end of the wheel frame 22 is rotatably connected to a traveling wheel 2. The wheel frame 22 rotates around its hinged part with the frame 1. The axle of the traveling wheel 2 is hinged or rotatably connected to the wheel frame 22, so that the wheel frame 22 can rotate along the hinged part to lift the traveling wheel 2. In this embodiment, two traveling wheels 2 are provided at the bottom end of the seeder, and one wheel frame 22 is correspondingly provided for one traveling wheel 2.

[0036] Referring to Figure 1 , in this embodiment, to ensure that the two traveling wheels 2 rotate synchronously around the hinge point of the frame 1, a support frame 21 is provided between the two wheel frames 22 to connect the two wheel frames 22, forming a moving whole in structure.

[0037] Referring to Figure 1 , a first oil cylinder 3 is provided on the wheel frame 22 of one of the traveling wheels 2. The cylinder end of the first oil cylinder 3 is hinged to the wheel frame 22, and the piston rod end of the first oil cylinder 3 is hinged to the axle of the traveling wheel 2. The cylinder end of the second oil cylinder 4 is hinged to the wheel frame 22, and the piston rod end of the second oil cylinder 4 is hinged to the axle of the traveling wheel 2. Furthermore, the operation of the piston rods of the two oil cylinders is used to lift and lower the two traveling wheels 2.

[0038] Referring to Figure 1 And Figure 2 , a hydraulic station 5 is provided in the middle part of the frame 1 for controlling, supplying, and transporting hydraulic oil in a traditional hydraulic system. The hydraulic station 5 is a prior art and mainly consists of a hydraulic transfer pump, a hydraulic cylinder, and a circuit control and processing module. In this embodiment, the hydraulic station 5 is provided between the first oil cylinder 3 and the second oil cylinder 4 to provide the hydraulic oil transfer power for the first oil cylinder 3 and the second oil cylinder 4. The hydraulic cylinder, hydraulic transfer pump, first oil cylinder 3, and second oil cylinder 4 of the hydraulic station 5 are connected to form a hydraulic oil circulation. The hydraulic transfer pump provides the power to transport the hydraulic oil in the hydraulic cylinder to the first oil cylinder 3 and the second oil cylinder 4. The oil inlet of the first oil cylinder 3 is opened at one end of the cylinder body away from the piston rod, and the oil outlet is opened at one end of the cylinder body close to the piston rod. The oil inlet of the second oil cylinder 4 is opened at one end of the cylinder body away from the piston rod, and the oil outlet of the second oil cylinder 4 is opened at one end of the cylinder body close to the piston rod. The setting method of the oil inlet and outlet of the hydraulic cylinder is relatively common. Among them, the oil outlet of the first oil cylinder 3 is connected to the oil inlet of the second oil cylinder 4, forming a cycle of a hydraulic oil tank - first oil cylinder 3 - second oil cylinder 4 - hydraulic oil tank. The transportation of the hydraulic oil in the two oil cylinders can be achieved through a single hydraulic oil pump 7.

[0039] Referring to Figure 1 AndFigure 2 , the volume of the first oil cylinder 3 is larger than that of the second oil cylinder 4. Specifically, the diameter of the first oil cylinder 3 is larger than that of the second oil cylinder 4. The volume of the oil at the oil outlet of the first oil cylinder 3 is restricted by the volume of the piston rod. When the piston rods of the first oil cylinder 3 and the second oil cylinder 4 extend by the same length, the diameter of the first oil cylinder 3 needs to be widened. While removing the volume occupied by the piston rod, the volume at the oil outlet of the first oil cylinder 3 needs to be adapted to the volume of the oil inlet of the second oil cylinder 4.

[0040] Refer to Figure 1 And Figure 2 , a component for ensuring stable transmission of hydraulic oil is provided between the first oil cylinder 3 and the second oil cylinder 4. When relying solely on one hydraulic oil pump 7, the hydraulic oil between the first oil cylinder 3 and the second oil cylinder 4 may not be stably transmitted. Therefore, in this embodiment, a hydraulic oil pump 7 for driving the transmission of hydraulic oil between the first oil cylinder 3 and the second oil cylinder 4 is provided between the first oil cylinder 3 and the second oil cylinder 4. The hydraulic oil pump 7 is in a normally closed state and operates only when the hydraulic system transmission is unstable, providing the circulating power for the hydraulic oil between the first oil cylinder 3 and the second oil cylinder 4.

[0041] Refer to Figure 1 And Figure 2 , the conveying pipelines between the first oil cylinder 3 and the second oil cylinder 4 are simultaneously connected to the hydraulic oil tank of the hydraulic station 5, thereby forming a tee structure on the hydraulic pipeline between the first oil cylinder 3 and the second oil cylinder 4. When the hydraulic oil transmission between the first oil cylinder 3 and the second oil cylinder 4 is unstable, the hydraulic oil cylinder supplements hydraulic oil to the second oil cylinder 4 to maintain the stability of the hydraulic system.

[0042] Refer to Figure 1 And Figure 2 , for the convenience of the user to monitor, in this embodiment, oil quantity detection meters 6 are provided at the tee of the first oil cylinder 3, the second oil cylinder 4, and the hydraulic oil tank, further speaking, in all three sections of the pipeline. The user can observe the transmission quantity and compensation quantity of the hydraulic oil in each section of the current hydraulic pipeline according to the oil quantity detection meters 6.

[0043] The implementation principle of a seeding machine with a hydraulic energy-saving component in the embodiment of this application is: by connecting the first oil cylinder 3 and the second oil cylinder 4, the two separate hydraulic systems in the prior art are connected, realizing that one transmission pump supplies two oil cylinders, saving the operation cost of the hydraulic cylinders.

[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
