The contact plates in four directions will act on the ground synchronously. Once there is a height difference in the ground, the limit plate will move in the movable plate, and the linear encoder will detect the movement value of the limit plate, so that the height difference can be quantified and displayed, and its horizontal state can be quickly and efficiently detected during the movement of the tail of the walking self-moving machine, thereby avoiding the placement tilt of a single or multiple frames, resulting in a loose connection of the conveyor.

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] like Figure 1-3 As shown, embodiment 1 of the present invention is a frame for a self-moving tail with a horizontal placement detection function, including a self-moving tail 1 and a frame 2, a reinforcing beam 3 is fixedly installed on the inner side of the frame 2, and a horizontal detection mechanism 4 is fixedly connected to the left side of the reinforcing beam 3. The self-moving tail 1 includes multiple frames 2 for connection, wherein a single or multiple frames 2 are provided with a reinforcing beam 3 on the inner side, and the number of installed reinforcing beams 3 is added or reduced according to actual measurement needs.

[0019] like Figure 1 , Figure 4 and Figure 5As shown, in Example 2 of the present invention, a frame for the tail of a self-propelled machine with a horizontal placement detection function is provided. On the basis of Example 1, a horizontal detection mechanism 4 includes a layer plate 40, a hydraulic cylinder 41, a movable plate 42, an adjustment arm 43, a limit plate 44, a shield 45, a rotating rod 46, a contact plate 47, an angle sensor 48 and a linear encoder 49. A hydraulic cylinder 41 is fixedly installed on the top of the layer plate 40, and a movable plate 42 located below the layer plate 40 is fixedly connected to the bottom end of the telescopic rod of the hydraulic cylinder 41. The plate 42 is provided with a plurality of limiting holes, and an adjusting arm 43 is sleeved inside the limiting holes. The top of the adjusting arm 43 is fixedly connected to a limiting plate 44 located above the movable plate 42, and the bottom of the adjusting arm 43 is fixedly connected to a shield 45. A rotating rod 46 is movably connected inside the shield 45, and a contact plate 47 is fixedly connected to the outside of the rotating rod 46. An angle sensor 48 is fixedly installed on one side of the shield 45, and the detection axis of the angle sensor 48 is connected to the rotating rod 46. Four wires are fixedly installed at the bottom of the movable plate 42. The connection end of the linear encoder 49 and the limit plate 44 are connected, wherein the hydraulic cylinder 41 is a driving element and is connected to the hydraulic equipment in the walking self-moving tail 1. When the walking self-moving tail 1 has finished moving forward, backward or left and right, the hydraulic cylinder 41 can be started to extend its telescopic end downward. During the extension process, the contact plate 47 will first contact the ground. During the contact process, the contact plate 47 will rotate according to the inclination of the ground, and the angle sensor 48 can monitor the rotation angle value of the contact plate 47, so as to obtain the precise value of the ground. The hydraulic cylinder 41 continues to extend, and the contact plates 47 in four directions will act on the ground synchronously. Once there is a height difference in the ground, the limit plate 44 will move in the movable plate 42, and the linear encoder 49 will detect the movement value of the limit plate 44, so that the height difference can be quantified and displayed, which can quickly and efficiently detect its horizontal state during the movement of the walking self-moving tail 1 to avoid the placement tilt of a single or multiple frames 2, resulting in a loose connection of the conveyor.

When the reset member 5 is in a vertical movement state, the shield 45 can be prevented from being offset during the detection process, thereby enhancing the detection accuracy.

[0021] like Figure 5As shown, embodiment 4 of the present invention is a frame for the tail of a stepped self-moving machine with a horizontal placement detection function. On the basis of embodiment 1, the inner sides of both ends of the shield 45 and the outer sides of both ends of the rotating rod 46 are fixedly connected with baffles 7, and the outer sides of both ends of the rotating rod 46 are sleeved with torsion springs 8, and the two ends of the torsion spring 8 are respectively connected to the baffles 7 on the shield 45 and the rotating rod 46. The contact plate 47 rotates when in contact with the ground to deform the torsion spring 8, and the baffle 7 on the rotating rod 46 and the shield 45 interact with each other to return the torsion spring 8, thereby resetting the contact plate 47 and improving the horizontal detection accuracy.

[0022] like Figure 4-5 As shown, embodiment 5 of the present invention is a frame for the tail of a stepped self-moving machine with a horizontal placement detection function. On the basis of embodiment 1, mounting holes are opened on the left and right sides of the shield 45, and a rotating shaft is installed inside the mounting hole. The rotating shaft and the rotating rod 46 are movably connected, which can make the rotating rod 46 rotate in the shield 45 and facilitate the connection between the rotating rod 46 and the angle sensor 48.

[0023] like Figure 4 As shown, embodiment 6 of the present invention is a frame for the tail of a self-moving machine with a horizontal placement detection function. On the basis of embodiment 1, two reset members 5 are fixedly connected to the bottom of the limit plate 44, and the bottom ends of the reset members 5 penetrate the movable plate 42 and extend downward. The outer sides of the reset members 5 and the bottom of the movable plate 42 are fixedly connected to the two ends of the linear spring 6 respectively. When the guard 45 moves due to the height difference of the ground, the limit plate 44 can be reset quickly and effectively, and the hydraulic cylinder 41 can perform measurements repeatedly to avoid measurement errors.
