Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a lifting device with an angle measurement function and a sprayer. Background Art

[0002] As sprayers become larger and more intelligent, the motion characteristics of each sprayer module need to be transmitted to the control system for unified control during operation. The sprayer's lifting mechanism is connected to the chassis module at one end and to the boom's central section at the other. The central section, in turn, connects to the boom module to control the boom's raising and lowering. The lifting mechanism is controlled by the extension and retraction of a hydraulic cylinder. However, the hydraulic cylinder cannot provide feedback on the actual height of the lifting mechanism, and therefore cannot transmit the actual position of the lifting mechanism to the control system. Utility Model Content

[0003] The utility model provides a lifting device and a sprayer with an angle measurement function, aiming to solve the problems in the prior art.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

One end of the lifting mechanism is connected to the chassis assembly for vertical rotation via a positioning pin. The angle sensor is installed on the chassis assembly, connected to the lifting mechanism via a connecting component, and is concentrically distributed with the positioning pin.

[0006] The beneficial effect of the utility model is that during operation, the hydraulic cylinder in the lifting mechanism is extended and retracted to drive the entire lifting mechanism to rise and fall, and at the same time, the lifting mechanism uses the connecting component to drive the rotating shaft of the angle sensor to rotate, thereby obtaining the lifting angle of the lifting mechanism.

[0011] Furthermore, the movable rod is a Z-shaped plate structure.

[0013] Furthermore, the other end of the moving rod is provided with an elongated hole, and the connecting assembly further comprises a positioning rod, which is fixedly mounted on the lifting mechanism and has one end extending into the elongated hole and slidably connected to the elongated hole.

[0014] The beneficial effect of adopting the above further solution is simple structure and reasonable design. The lifting mechanism uses the positioning rod to pull the moving rod to operate, and then the moving rod drives the rotating shaft of the angle sensor to rotate, thereby knowing the lifting angle of the lifting mechanism.

[0015] Furthermore, the connecting component also includes a bracket, which is fixedly mounted on the chassis assembly; and the angle sensor is mounted on the bracket.

[0016] The beneficial effects of adopting the above further solution are simple structure, reasonable design, and easy assembly by using the bracket to assemble the angle sensor.

The bracket is fixed to the chassis assembly by the bracket positioning screw, and the angle sensor is fixed to the bracket by the sensor positioning screw, which is convenient for assembly.

[0019] Furthermore, the rotation axis of the angle sensor passes through one end of the moving rod.

[0021] Furthermore, a sensor positioning pin is installed on the rotating shaft of the angle sensor to prevent one end of the moving rod from slipping off.

[0022] The beneficial effects of adopting the above further solution are simple structure and reasonable design, and the sensor positioning pin can be used to prevent one end of the moving rod from slipping off the rotating shaft of the angle sensor.

[0067] Example 9

[0068] On the basis of the above embodiments, this embodiment further includes a control unit, and the lifting mechanism 1 and the angle sensor 5 are respectively connected to the control unit for communication.

[0069] This solution has a simple structure and a reasonable design. It uses the angle sensor 5 to directly obtain the lifting angle of the lifting mechanism 1 and directly transmits the signal to the control unit (equivalent to the controller in the prior art).

[0070] Example 10

[0071] On the basis of the above embodiments, this embodiment further provides a sprayer, comprising the lifting device with the angle measurement function as described above.

[0072] This embodiment also provides a sprayer with a simple structure and reasonable design. The sprayer can identify the actual lifting position of the sprayer lifting mechanism and transmit it to the control unit, solving the problem of being unable to detect the lifting angle of the lifting mechanism.

[0073] The working principle of this utility model is as follows:

[0074] During the operation, the hydraulic cylinder in the lifting mechanism 1 is extended and retracted to drive the entire lifting mechanism 1 to rise and fall. At the same time, the lifting mechanism 1 uses the positioning rod 3 to pull the moving rod 2 to move, and then the moving rod 2 drives the rotating shaft of the angle sensor 5 to rotate, so that the angle sensor 5 obtains the lifting angle of the lifting mechanism 1 and sends the corresponding signal to the control unit.

[0075] As the lifting mechanism 1 rises and falls around the lifting device positioning pin 9, it moves the positioning rod 3 above it. Positioning rod 3, which is located in the elongated hole of the moving rod 2, drives the moving rod 2 in motion. Because the lifting device positioning pin 9 of the lifting mechanism 1 and the rotation axis of the angle sensor 5 are concentric, the lifting device's lifting angle and the sensor's sensing angle are consistent. This structure can detect the lifting device's lifting angle and provide feedback to the control center for appropriate control.

[0076] The purpose of this utility model is to design a structure that can solve the problem of identifying the actual lifting position of the sprayer lifting mechanism and transmitting it to the control system. One end of the sprayer lifting mechanism is connected to the chassis through a positioning pin on the chassis and can rotate freely along the pin as the center. The angle sensor is installed on the chassis module through a bracket, and the center of the sensor's sensing axis is concentric with the positioning pin on the chassis. The moving rod on the sensor's pin moves with the positioning rod on the lifting mechanism. The sensor's sensing angle is consistent with the angle of the lifting mechanism, and then the sensor feedback angle is the lifting angle of the lifting mechanism.

[0077] The utility model adopts a mechanical mechanism to solve the problem that the lifting angle of the lifting mechanism cannot be detected. The mechanical structure is simple and reliable, and the angle detection at any position of the lifting device can be detected.

[0078] It should be noted that all electronic components involved in the present invention adopt existing technologies, and the above components are electrically connected to the controller, and the control circuits between the controller and the components are existing technologies.
