DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The existing support seat can only adjust the height of the excavator, but cannot adjust the angle of the excavator. The adjustment function is limited. When the excavator is working on a slope, it is difficult for the body to remain level, and the orientation of the body cannot be adjusted, resulting in the equipment needing to move frequently when excavating materials in different positions, reducing efficiency.

[0024] To solve the defects of the above support seat during use, please refer to Figure 1-Figure 5The utility model provides an adjustable excavator support seat, which can not only adjust the height of the excavator, but also adjust the angle of the excavator, thereby enhancing the practicability of the equipment. The supporting seat is composed of a base 1, a middle rotating seat 2, a bracket 3 and a bearing seat 4 which are arranged in sequence from bottom to top as the basic structure. The four corners of the bearing seat 4 are provided with mounting holes 11. The bearing seat 4 is used to carry the excavator. The excavator bottom plate is mounted on the bearing seat 4 by fastening bolts to ensure the stability of the excavator on the bearing seat 4. The bearing seat 4 is rotatably mounted inside the bracket 3. Through grooves 8 are provided on both sides of the bracket 3. A limiting mechanism 7 for adjusting the vertical angle of the bearing seat 4 is provided inside the through groove 8. The vertical angle of the excavator can be adjusted by rotating the bearing seat 4. The bearing seat 4 can be limited by the limiting mechanism 7. The bearing seat 4 can be fixed by locking it. Both ends of the bearing seat 4 are fixedly connected with a turntable 9 through the bracket 3. A plurality of evenly distributed limiting grooves 10 are provided on the outer edge of the turntable 9. The bearing seat 4 can be prevented from rotating by limiting the limiting grooves 10. In order to limit the limiting grooves 10, the sliding rod 71 is fixedly mounted in the through groove 8, and the outer sliding sleeve of the sliding rod 71 is provided with The top of the slider 72 is fixedly connected with a limiting rod 74 that is compatible with the limiting groove 10. The top of the limiting rod 74 is provided with an arc surface to facilitate the limiting rod 74 to be inserted into the limiting groove 10. After the limiting rod 74 is inserted into the limiting groove 10, the limiting groove 10 is prevented from rotating, so that the bearing seat 4 can be fixed. In order to prevent the limiting rod 74 from falling off from the limiting groove 10, a telescopic spring 73 is sleeved on the outside of the slider 72. The upper end of the telescopic spring 73 is fixedly connected to the bottom of the slider 72, and the lower end of the telescopic spring 73 is fixedly connected to the bottom of the slider 72. The inner bottom wall of the through groove 8 is fixedly connected, and the limiting rod 74 can be pushed into the limiting groove 10 by the elastic force of the telescopic spring 73. Both sides of the slider 72 are fixedly connected with pressure rods 75. Pressing the pressure rod 75 downward can conveniently drive the limiting rod 74 to move out of the limiting groove 10, and then the angle of the bearing seat 4 can be readjusted. By adjusting the angle of the bearing seat 4 in the vertical direction, the bearing seat 4 can still remain horizontal when the equipment is used on a slope, which makes it convenient for the equipment to be applied to different terrains and ensures the normal operation of the excavator.

[0025] When the excavator is in use, it is usually necessary to excavate materials at different positions. When excavating materials in different directions, the staff may need to frequently move the position of the excavator to ensure that the excavator arm corresponds to the material. This process will lead to a decrease in excavation efficiency. In order to solve this technical problem, a horizontal adjustment mechanism 5 for adjusting the horizontal angle of the bracket 3 is provided on the transfer seat 2, wherein a connecting rod 51 is rotatably installed at the bottom of the transfer seat 2, and the bracket 3 is fixedly installed at the upper end of the connecting rod 51. A worm gear 52 is provided on the external fixed sleeve of the connecting rod 51. A servo motor 54 is fixedly installed on one side of the top of the transfer seat 2. A worm 53 is fixedly connected to the output end of the servo motor 54. The worm 53 is meshed with the worm gear 52. Driving the servo motor 54 can drive the worm 53 to rotate. The rotation of the worm 53 can drive the worm gear 52 to rotate. The rotation of the worm gear 52 drives the bracket 3 to rotate through the connecting rod 51. The rotation of the bracket 3 can adjust the horizontal angle of the bearing seat 4, thereby facilitating the excavator to excavate materials in different directions without frequently moving the position of the equipment, thereby improving the excavation efficiency.

[0026] In order to achieve height adjustment of the excavator, a height adjustment mechanism 6 for adjusting the height of the transfer seat 2 is provided on the base 1, wherein a bidirectional screw 61 is rotatably installed inside the base 1, and the thread on the outer surface of the bidirectional screw 61 is two sections with opposite rotation directions. A servo motor 62 is fixedly installed at the end of the base 1, and the output end of the servo motor 62 is fixedly connected to the axis of the bidirectional screw 61, and both ends of the bidirectional screw 61 are threadedly connected to a sliding seat 63, and the sliding seat 63 is slidably connected to the base 1. A connecting rod 64 is rotatably connected to the sliding seat 63, and the upper end of the connecting rod 64 is hinged to the bottom of the transfer seat 2. Driving the servo motor 62 can drive the bidirectional screw 61 to rotate, and the rotation of the bidirectional screw 61 drives the two sliding seats 63 to slide, and the sliding seat 63 drives the connecting rod 64 to rotate. The rotation of the connecting rod 64 can drive the transfer seat 2 to rise and fall, thereby adjusting the height of the supporting seat 4.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
