DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] like Figure 1 - Figure 7As shown, the utility model provides an automatic grabbing device for waste rock on a belt, including a mechanical arm 1, a protective cover 3 is provided on the outer side of the lower end of the mechanical arm 1, and a side groove 4 is provided on the outer surface of the protective cover 3. The lower end of the mechanical arm 1 is fixedly connected to a bottom mounting plate 10, and a threaded hole 19 is provided inside the bottom mounting plate 10. The threaded hole 19 is internally threadedly connected to a threaded rod 17, and one end of the threaded rod 17 is fixedly connected to a ball head 11. A base structure is provided below the mechanical arm 1, and the base structure includes a support plate 12, a support plate 13, and a support plate 14. A guide groove 14 is provided on the upper surface of 12, and a limiting ring 13 is fixedly connected to the outer edge of the upper end of the support plate 12. The inner ring surface of the limiting ring 13 fits with the outer surface of the protective cover 3. The number of threaded holes 19 is at least three, and the center points of two adjacent threaded holes 19 are connected to each other. A polygon is formed according to the number of threaded holes 19. The center of gravity of the polygon is on the same vertical line as the center of gravity of the bottom mounting plate 10 to ensure stability during use. The distance from each threaded hole 19 to the center of gravity of the bottom mounting plate 10 is not equal.

[0027] The following is a detailed description of the specific settings and functions of this embodiment. By setting the ball head 11 and the guide groove 14, when installing the robot arm 1, the robot arm 1 can be directly placed on the top of the support plate 12, and the outer surface of the protective cover 3 is in contact with the inner surface of the limiting ring 13 to complete the initial positioning. The hand holds the side of the side groove 4 and rotates the robot arm 1. Because the position of the ball head 11 from the center of gravity is different, it can only be connected to the guide groove 14 when it is rotated to a fixed position. When the ends of the grooves 14 are in contact, the lower end surface of the bottom mounting plate 10 is in a fit state with the lower end surface of the support plate 12. At the same time, the connecting holes on the bottom mounting plate 10 are connected with the connecting holes on the support plate 12, and the positioning is completed. In this way, the positioning is faster and the installation is simpler without the need for multiple debugging. The round head is used, and the contact surface with the support plate 12 is smaller, which makes it easier to rotate and easier to install. At the same time, the ball head 11 is connected to the bottom mounting plate 10 by a threaded manner, which can be easily replaced when it is worn out after repeated use.

[0028] Example 2

[0029] like Figure 1 - Figure 5As shown, a clamping claw 2 is installed at one end of the robotic arm 1, the lower end of the support plate 12 is fixedly connected to the No. 1 support frame 6, the lower end of the No. 1 support frame 6 is fixedly connected to the mounting plate 7, the lower end of the mounting plate 7 is fixedly connected to the No. 2 support frame 9, the lower end of the No. 2 support frame 9 is fixedly connected to the funnel plate 8, the upper end of the protective cover 3 is provided with a protective pad 5, the lower end of the protective pad 5 is fixedly connected to an inner retaining ring 15 and a sealing ring 16, the outer ring surface of the inner retaining ring 15 is in contact with the inner ring surface of the upper end of the protective cover 3, the lower end of the sealing ring 16 is in contact with the robotic arm 1, the outer surface of the ball head 11 is provided with a hexagonal groove 18, the protective pad 5 and the inner retaining ring 15 are produced by plastic with higher hardness, and the sealing ring 16 is a soft rubber ring for sealing.

[0030] The effect achieved by the entire embodiment is that, through the setting of the protective pad 5, it is used to protect the area inside the robotic arm 1 and the protective cover 3, to prevent dust from entering the side groove 4, so as to avoid dust entry, ensure the normal use of the robotic arm 1, and prevent damage. Through the setting of the funnel plate 8, it is used to be buried underground when in use, which can increase the connection strength with the ground and increase stability.

[0031] The method of use and working principle of this device: During installation, first bury the funnel plate 8 and the second support frame 9 underground, make the ground surface of the mounting plate 7 flush with the ground, then install the driving device on the top of the mounting plate 7, and then place the robot arm 1 on the top of the support plate 12, and make the outer surface of the protective cover 3 contact the inner surface of the limiting ring 13 to complete the preliminary positioning, hold the side of the side groove 4 with your hand, and rotate the robot arm 1. Because the position of the ball head 11 from the center of gravity is different, it can only be aligned with the guide when it is rotated to a fixed position. The guide groove 14 is connected. When the ball head 11 contacts the end of the guide groove 14, the lower end surface of the bottom plate 10 is in a fit state with the lower end surface of the support plate 12. At the same time, the connecting hole on the bottom plate 10 is connected with the connecting hole on the support plate 12, and the positioning is completed. Then, the bottom plate 10 and the support plate 12 are fixed with bolts, and the driving device is connected to the robot arm 1 to control the rotation of the robot arm 1. When in use, the waste rock on the belt is grabbed by the clamping claw 2 to prevent the remaining ore from being put into the waste rock basket for subsequent processing to produce bentonite.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
