Description

Technical Field

[0001] This application relates to the field of agricultural equipment technology, and in particular to a test platform for the tilt angle of a tracked rotary tiller. Background Technology

[0002] In the field of agricultural equipment, tracked rotary tillers are a common type of workpiece. During field operations, they may tip over due to ground slope, uneven load distribution, or improper operation. To ensure the safety of tracked rotary tillers, it is necessary to test their tipping limit angle. However, traditional testing devices lack an effective braking mechanism. If an unexpected power outage or mechanical failure occurs during angle adjustment, the adjustment platform may lose control and fall, posing a safety hazard. Therefore, there is an urgent need for a highly safe tracked rotary tiller tipping angle testing platform to solve the aforementioned technical challenges. Summary of the Invention

[0003] The purpose of this application is to provide a tracked rotary tiller tilt angle testing platform to solve the above problems. It adopts a safety braking system design to prevent the tilting platform from falling accidentally and to ensure absolute safety during the testing process.

[0004] This application achieves the above objectives through the following technical solutions:

[0005] A tilt angle testing platform for a tracked rotary tiller includes: a base, an angle adjustment platform, a hydraulic cylinder, a first hinged support, a second hinged support, an arc-shaped rod, an electromagnetic brake, and brake shoes. One side of the angle adjustment platform is connected to the base via the second hinged support. The output end of the hydraulic cylinder is connected to the base via the first hinged support. The fixed end of the hydraulic cylinder is hinged to the base. The end of the arc-shaped rod is fixedly connected to the bottom of the angle adjustment platform. The electromagnetic brake is fixedly mounted on the base. The arc-shaped rod is clamped between the brake shoes of the electromagnetic brake, allowing the brake shoes to grip the arc-shaped rod or separate from it. An clearance opening is provided at the bottom of the base for the hydraulic cylinder and the arc-shaped rod to pass through.

[0006] Furthermore, it also includes: a guardrail and a ramp, with the guardrail fixedly connected to the side where the angle adjustment platform connects to the base, and the ramp located at the end of the base.

[0007] Furthermore, it also includes a connecting block and a support block. The connecting block is fixedly connected to the fixing part of the hydraulic cylinder, the support block is fixedly connected to the base, and the connecting block and the support block are rotatably connected.

[0008] Furthermore, the axial direction of the arc-shaped rod is coaxial with the rotation center of the angle adjustment platform.

[0009] Furthermore, a connecting flange is fixedly connected to the end of the arc-shaped rod, and the connecting flange is fixedly connected to the angle adjustment platform by fasteners.

[0010] Furthermore, a buffer layer is provided on the side of the guardrail facing the tracked rotary tiller.

[0011] Furthermore, the hydraulic cylinder is tilted.

[0012] Compared to existing technologies, this application adopts a safety braking system design, which links the electromagnetic brake with the brake shoes. The arc-shaped rod is embedded between the brake shoes of the electromagnetic brake. When energized, the brake shoes separate, allowing the angle adjustment platform to flexibly adjust the angle. When de-energized, the brake shoes automatically grip the arc-shaped rod through the spring to prevent the angle adjustment platform from falling accidentally, ensuring absolute safety during the testing process.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figure 1-3As shown, a tilt angle testing platform for a tracked rotary tiller includes: a base 1, an angle adjustment platform 2, a hydraulic cylinder 5, a first hinge support 6, a second hinge support 7, an arc-shaped rod 10, an electromagnetic brake 12, and brake shoes 13. One side of the angle adjustment platform 2 is connected to the base 1 through the second hinge support 7. The output end of the hydraulic cylinder 5 is connected to the base 1 through the first hinge support 6. The fixed end of the hydraulic cylinder 5 is hinged to the base 1. The end of the arc-shaped rod 10 is fixedly connected to the bottom of the angle adjustment platform 2. The electromagnetic brake 12 is fixedly mounted on the base 1. The arc-shaped rod 10 is clamped between the brake shoes 13 of the electromagnetic brake 12, so that the brake shoes 13 can grip the arc-shaped rod 10 or separate from it. The bottom of the base 1 has an clearance opening for the hydraulic cylinder 5 and the arc-shaped rod 10 to pass through.

[0022] Specifically, the base 1 is box-shaped with an open top and a reinforcing plate in the middle to support the horizontal angle-adjusting platform 2. The two ends of the second hinged support 7 are fixedly connected to the base 1 and the angle-adjusting platform 2 respectively to support the rotation of the angle-adjusting platform 2. After the output end of the hydraulic cylinder 5 is hinged to the first hinged support 6, the hydraulic cylinder 5 can rotate synchronously to adapt to the angle of the angle-adjusting platform 2 when the angle of the angle-adjusting platform 2 changes. The arc rod 10 can rise and fall with the change of the angle of the angle-adjusting platform 2. At the same time, the arc of the arc rod 10 can make it stay between the brake shoes 13 when it rises and falls, so that the electromagnetic brake 12 can hold the arc rod 10 through the brake shoes 13 to prevent the angle-adjusting platform 2 from falling accidentally and ensure safety. The electromagnetic brake 12 is existing technology and can apply pressure to the brake shoes 13 through the action of the spring when the power is off, so that the brake shoes 13 hold the arc rod 10.

[0023] Furthermore, it also includes: guardrail 3 and inclined platform 4. Guardrail 3 is fixedly connected to the side where the angle adjustment platform 2 is connected to the base 1, and inclined platform 4 is located at the end of the base 1.

[0024] Specifically, guardrail 3 can prevent the tracked rotary tiller from tilting to the side, prevent it from tilting further, and prevent the tracked rotary tiller from overturning. The slope of ramp 4 can facilitate the movement of the tracked rotary tiller to the top.

[0025] Furthermore, it also includes a connecting block 8 and a support block 9. The connecting block 8 is fixedly connected to the fixing part of the hydraulic cylinder 5, and the support block 9 is fixedly connected to the base 1. The connecting block 8 and the support block 9 are rotatably connected.

[0026] Specifically, the connecting block 8 is fixedly connected to the fixed part of the hydraulic cylinder 5 to stably support the hydraulic cylinder 5. At the same time, the connecting block 8 is rotatably connected to the support block 9, which can support the hydraulic cylinder 5 to change its angle to adapt to the angle of the angle adjustment platform 2.

[0027] Furthermore, the axial direction of the arc-shaped rod 10 is coaxial with the rotation center of the angle adjustment platform 2, so that when the angle adjustment platform 2 changes angle, the arc-shaped rod 10 can always be in the area where the brake shoe 13 can hold it.

[0028] Furthermore, a connecting flange 11 is fixedly connected to the end of the arc-shaped rod 10. The connecting flange 11 is fixedly connected to the angle adjustment platform 2 by fasteners, so that the arc-shaped rod 10 can be fixedly installed on the angle adjustment platform 2 through the connecting flange 11.

[0029] Furthermore, the guardrail 3 has a buffer layer on the side facing the tracked rotary tiller to further protect the tracked rotary tiller and prevent damage.

[0030] Furthermore, the hydraulic cylinder 5 is tilted to give it good performance in tilting the angle adjustment platform 2.

[0031] In the above structure, when installing this test platform, a portion of the ground needs to be excavated to allow for the movement of the hydraulic cylinder 5 and the arc-shaped rod 10. The angle adjustment platform 2 is adjusted to a horizontal position. The tracked rotary tiller travels onto the angle adjustment platform 2 via the inclined platform 4. Then, based on the hydraulic station, the hydraulic cylinder 5 is driven to extend and retract. The angle adjustment platform 2, which is hinged to the hydraulic cylinder 5 via the first hinge support 6, rotates around the second hinge support 7 to adjust the angle. The angle adjustment platform 2 and the tracked rotary tiller tilt together until the tracked rotary tiller tilts onto the guardrail 3. At this point, the maximum tilt angle of the tracked rotary tiller is detected. When adjusting the angle of the angle adjustment platform 2, the electromagnetic brake 12 is energized to separate the brake shoe 13 from the arc-shaped rod 10, allowing the angle adjustment platform 2 to smoothly adjust its angle. When the power is off, the brake shoe 13, under the action of the spring on the electromagnetic brake 12, grips the arc-shaped rod 10 to brake it, thereby preventing the angle adjustment platform 2 from rising or falling, thus positioning the angle adjustment platform 2 and preventing accidental falls, ensuring safety.
