[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, an automatic control device for a hydraulic boom includes a base 1, a protective shell 2 on the top of the base 1, a control box 3 on the top of the base 1 and on one side of the protective shell 2, telescopic sleeves 4 rotatably mounted at the four corners of the base 1, and bolts 5 between the base 1 and the four telescopic sleeves 4. The top of the protective shell 2 is provided with a hydraulic arm mechanism 6, the inside of the telescopic sleeve 4 is provided with a sliding groove 7, a sliding component 8 is slidably installed inside the sliding groove 7, and the top of the telescopic sleeve 4 is provided with an adjustment mechanism 12.

[0023] In this embodiment, after the device is moved to a suitable position, the sliding member 8 is adjusted to a suitable length by the adjusting mechanism 12, and the wrench 11 is turned so that the four foot pads 10 lift the device, and then the operation is completed by the hydraulic arm mechanism 6.

[0024] In one embodiment, such as Figure 2 and Figure 3As shown, the adjusting mechanism 12 includes a mounting sleeve 121, which is fixedly mounted on the top of the telescopic sleeve 4. A pin 122 is slidably mounted inside the mounting sleeve 121. A fixing plate 123 is provided outside the pin 122. The top end of the pin 122 passes through the mounting sleeve 121 and is connected to a handle 124. A spring 125 is sleeved outside the pin 122 and above the fixing plate 123. Multiple positioning holes 13 are equidistantly opened on the top of the sliding member 8. The bottom end of the pin 122 is inserted into the sliding member 8 through the positioning holes 13. A threaded rod 9 with a threaded connection passes through the top of the sliding member 8. A foot pad 10 is rotatably mounted on the bottom end of the threaded rod 9. A wrench 11 is provided on the top end of the threaded rod 9 for adjusting the sliding member 8. When the length is adjusted, hold the handle 124 to lift the pin 122 upwards, compress the spring 125, and the pin 122 leaves the positioning hole 13 and enters the interior of the mounting sleeve 121. At this time, the slider 8 can slide inside the slide groove 7, thereby changing the position of the slider 8. When the slider 8 is adjusted to the appropriate position, slowly loosen the handle 124. Due to the reset action of the spring 125, the pin 122 moves downwards and inserts into the interior of the positioning hole 13, so that the slider 8 is fixed with the telescopic sleeve 4. The structure is simple and easy to adjust according to needs. Then turn the wrench 11, and the wrench 11 drives the threaded rod 9 to rotate. The rotation of the threaded rod 9 changes the position of the foot pad 10. After the foot pad 10 contacts the ground, continue to turn the wrench 11 to separate the wheel 15 from the ground and improve the stability of the device placement.

[0025] In one embodiment, such as Figure 1 and Figure 4 As shown, the hydraulic arm mechanism 6 includes a rotating base 61, which is rotatably mounted on the top of the protective shell 2. A fixed frame 62 is provided on the top of the rotating base 61. A first rotating component 63 is rotatably mounted inside the fixed frame 62. A second rotating component 64 is rotatably mounted at one end of the first rotating component 63, and a third rotating component 65 is rotatably mounted at one end of the second rotating component 64. A first hydraulic cylinder 66 is rotatably mounted between the fixed frame 62 and the first rotating component 63. A second hydraulic cylinder 67 is rotatably mounted between the first rotating component 63 and the second rotating component 64. The second rotating component 64 and the first rotating component 65... A third hydraulic cylinder 68 is rotatably mounted between the three rotating parts 65. A drive assembly is provided inside the protective shell 2. The rotating seat 61 is driven by the drive assembly. The operation of the drive assembly causes the rotating seat 61 to rotate, changing the direction of the third rotating part 65. The third rotating part 65 is used to connect with the functional component and can perform digging or lifting operations. By controlling the extension and retraction of the first hydraulic cylinder 66, the first rotating part 63 can be rotated. By controlling the extension and retraction of the second hydraulic cylinder 67, the second rotating part 64 can be rotated. By controlling the extension and retraction of the third hydraulic cylinder 68, the third rotating part 65 can be rotated, which can be easily adjusted according to needs.

[0026] In one embodiment, such as Figure 1 As shown, a push handle 14 is provided on the top of the base 1 and outside the control box 3, and four wheels 15 are rotatably installed on the bottom of the base 1. The push handle 14 and the wheels 15 cooperate to facilitate short-distance movement of the device.

[0027] The above embodiment discloses an automatic control device for a hydraulic boom. The push handle 14, in conjunction with the wheel 15, facilitates short-distance movement of the device. After the device is moved to a suitable position, the handle 124 is used to lift the pin 122 upwards, compressing the spring 125. The pin 122 leaves the positioning hole 13 and enters the interior of the mounting sleeve 121. At this time, the sliding member 8 can slide inside the sliding groove 7, thereby changing the position of the sliding member 8. When the sliding member 8 is adjusted to a suitable position, the handle 124 is slowly released. Due to the reset effect of the spring 125, the pin 122 moves downwards and inserts into the positioning hole 13, fixing the sliding member 8 to the telescopic sleeve 4. The structure is simple and easy to adjust according to needs. Then, the wrench 11 is rotated, causing the threaded rod 9 to rotate. The rotation of the threaded rod 9 changes the position of the foot pad 10. After the foot pad 10 contacts the ground, the wrench 11 is rotated again, causing the wheel 15 to separate from the ground, improving the stability of the device placement.

[0028] The hydraulic arm mechanism 6 is controlled by the control box 3. The drive component works to drive the rotating seat 61 to rotate, changing the direction of the third rotating component 65. The third rotating component 65 is used to connect with the functional component and can perform digging or lifting operations. By controlling the extension and retraction of the first hydraulic cylinder 66, the first rotating component 63 can be driven to rotate. By controlling the extension and retraction of the second hydraulic cylinder 67, the second rotating component 64 can be driven to rotate. By controlling the extension and retraction of the third hydraulic cylinder 68, the third rotating component 65 can be driven to rotate, which can be easily adjusted according to needs.
