[0002] With the increasing development of automated equipment, automatically controlled or remotely controlled bulldozers are becoming more and more mature. Before the bulldozer is put into operation, the posture of the bucket needs to be calibrated so that the program can accurately control the bucket movement.

[0003] For the posture calibration of the bucket, the current method is to install an antenna on the back of the bucket to collect position and angle information, and place the antenna in a vertical state when the bucket is horizontal. This can clearly determine the relative position between the bucket posture and the antenna, so that the angle and position information of the bucket can be accurately obtained through the angle and position information of the antenna.

[0004] However, the back of the bucket is an inclined or curved surface. When the antenna is accurately installed on this surface, it is difficult to ensure that the antenna is in a vertical state when the bucket is horizontal. As a result, the posture of the bucket cannot be accurately positioned, affecting the accuracy of the automatic control of the bulldozer. Summary of the Invention

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] Please refer to Figure 1-Figure 5 The utility model discloses a mounting bracket for a bulldozer antenna. The bulldozer has a bucket 300. The back of the bucket 300 is used to mount an antenna 200. The mounting bracket 100 includes:

[0033] A first mounting plate 110 and a second mounting plate 120, wherein the first mounting plate 110 and the second mounting plate 120 are rotatably connected, and an end of the first mounting plate 110 away from the second mounting plate 120 is in contact with the inclined surface, and an end of the second mounting plate 120 away from the first mounting plate 110 is in contact with the inclined surface;

[0034] The antenna 200 is mounted on the first mounting plate 110 .

[0035] The present application provides a first mounting plate 110 and a second mounting plate 120 that can rotate relative to each other, so that by rotating one of the mounting plates, the other mounting plate is also rotated, thereby achieving angle adjustment of the antenna 200, so that the antenna 200 can be accurately installed on an inclined surface or curved surface.

[0036] Specifically, first, the bulldozer bucket 300 is aligned and leveled, with the first mounting plate 110 resting against the back of the bucket 300. Then, the lower end of the second mounting plate 120 is kept in contact with the back of the bucket 300, and the second mounting plate 120 is gradually rotated, driving the first mounting plate 110 and, in turn, the antenna 200 on the first mounting plate 110 until the antenna 200 is adjusted to a vertical position. Finally, the first and second mounting plates 110, 120 are secured to the back of the bucket 300, completing the calibration of the bucket 300. From this point on, the antenna 200 moves with the bucket 300, and the relative position between the antenna 200 and the bucket 300 remains unchanged, ensuring high-precision automatic control of the bucket 300.

[0037] Of course, you can also first place one end of the second mounting plate 120 against the back of the bucket 300, and then keep one end of the first mounting plate 110 always in contact with the back of the bucket 300 and gradually rotate the first mounting plate 110 until the first mounting plate 110 drives the antenna 200 to be adjusted to a vertical state.

[0038] Furthermore, the first mounting plate 110 is recessed inwardly on one side facing the second mounting plate 120 to form an arc-shaped groove 111;

[0039] An arc-shaped protrusion 121 is formed on one end of the second mounting plate 120 facing the first mounting plate 110 . The arc-shaped protrusion 121 can extend into the arc-shaped groove 111 and fit in with the bottom surface of the arc-shaped groove 111 .

[0040] It should be noted that during calibration, one end of either the first mounting plate 110 or the second mounting plate 120 must first be placed against a certain position on the back of the bucket 300. This position must not shift as the other mounting plate rotates. Otherwise, the angle of the antenna 200 will also change with the position of the contact, making it difficult to control the angle of the antenna 200. However, due to the inclined or curved back surface of the bucket 300, the rotation of one mounting plate can easily affect the other mounting plate and cause it to slip against the back of the bucket 300, resulting in calibration failure.

[0041] Based on this, in this case, an arc-shaped groove 111 is set at one end of the first mounting plate 110, and an arc-shaped protrusion 121 is set on the second mounting plate 120. The end of the arc-shaped protrusion 121 has an arc surface, and the arc-shaped protrusion 121 extends into the arc-shaped groove 111 so that the arc surface fits with the bottom surface of the arc-shaped groove 111, so that the first mounting plate 110 and the second mounting plate 120 maintain a sufficiently large contact area during the rotation process. In the process of rotating the first mounting plate 110 or the second mounting plate 120, the other mounting plate has a more stable posture and rotates synchronously therewith, and always maintains contact with the back of the bucket 300, so that the angle adjustment process of the antenna 200 is more stable and easier to control.

[0042] Furthermore, the first mounting plate 110 and the second mounting plate 120 may be fixed by welding.

[0043] Specifically, after adjusting the angles of the first mounting plate 110 and the second mounting plate 120 until the antenna 200 is in a vertical state, the first mounting plate 110 and the second mounting plate 120 are welded to the back of the bucket 300 to complete the angle calibration of the antenna 200.

[0044] Furthermore, a connecting piece 140 is provided on both sides of the first mounting plate 110 / the second mounting plate 120 respectively, one end of the connecting piece 140 is rotatably connected to the first mounting plate 110, and the other end of the connecting piece 140 is rotatably connected to the second mounting plate 120.

[0045] Specifically, a connecting piece 140 is provided on both sides of the two mounting plates, so that both ends of the connecting piece 140 are rotatably connected to the first mounting plate 110 and the second mounting plate 120, respectively, to achieve a rotatable connection between the first mounting plate 110 and the second mounting plate 120.

[0046] Furthermore, a through hole is formed on the connecting piece 140, and threaded holes are formed on both the first mounting plate 110 and the second mounting plate 120;

[0047] A fixing screw 141 is also included, one end of which passes through the through hole and is threadedly connected to the threaded hole.

[0048] Furthermore, in order to enable the second mounting plate 120 to rotate smoothly, the fixing screw 141 on the second mounting plate 120 is coaxially arranged with the rotating shaft of the second mounting plate 120, so that the connecting plate 140 will not rotate during the rotation of the second mounting plate 120, ensuring that the first mounting plate 110 has a more stable posture during the rotation of the second mounting plate 120.

[0049] Furthermore, one end of the first mounting plate 110 away from the second mounting plate 120 is welded and fixed to the inclined surface, and one end of the second mounting plate 120 away from the first mounting plate 110 is welded and fixed to the inclined surface.

[0050] Specifically, after the angles of the first mounting plate 110 and the second mounting plate 120 are adjusted, the first mounting plate 110 and the second mounting plate 120 may be fixed by welding.

[0051] Furthermore, an extension rod 130 is included, one end of the extension rod 130 is detachably connected to the first mounting plate 110 , and the antenna 200 is installed on the other end of the extension rod 130 .

[0052] Specifically, an extension rod 130 is provided so that the lower end of the extension rod 130 is connected to the first mounting plate 110, and the antenna 200 is installed on the upper end of the extension rod 130, so that the antenna 200 has a higher height, and there is a larger distance between the antenna 200 and the rotating axis of the bucket 300. When the bucket 300 is in motion, the antenna 200 has a larger range of movement, so that the antenna 200 can collect more accurate position information and angle information.

[0053] At the same time, increasing the height of the antenna 200 can also avoid the bulldozer components behind the bucket 300 as much as possible, so that the antenna 200 is placed in a wider space, allowing it to emit clearer signals.

[0054] Furthermore, a mounting plate 132 is provided at the lower end of the extension rod 130 . The cross-sectional area of ​​the mounting plate 132 is larger than the cross-sectional area of ​​the extension rod 130 . The lower surface of the mounting plate 132 is in contact with the upper surface of the first mounting plate 110 .

[0055] A plurality of reinforcing plates 131 are disposed between the mounting plate 132 and the extension rod 130 .

[0056] The mounting plate 132 is bolted to the first mounting plate 110 .

[0057] Specifically, the installation plate 132 can increase the contact area between the extension rod 130 and the first mounting plate 110 , making the connection between the extension rod 130 and the first mounting plate 110 more stable, and the extension rod 130 is not easy to loosen during the movement of the bucket 300 .

[0058] At the same time, a plurality of reinforcing plates 131 are provided between the mounting plate 132 and the extension rod 130 to enhance the connection strength between the extension rod 130 and the mounting plate 132 and prevent cracks or even breakage at the connection between the extension rod 130 and the mounting plate 132 .

[0059] Furthermore, the extension rod 130 is vertically mounted on the first mounting plate 110 through the mounting plate 132. When adjusting the angle of the first mounting plate 110 and the second mounting plate 120, the antenna 200 can be placed in a vertical state by simply adjusting the angle of the first mounting plate 110 to a horizontal position.

[0060] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0062] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0063] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
