DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-7 The present invention provides a technical solution: a grille 1, a column 2, a crossbeam 3, a tooth plate 4, a first gear 5, a first motor 6, a connecting plate 7, a connecting block 8, a second gear 9, a second motor 10, a threaded rod 11, a moving block 12, a limit rod 13, a pneumatic breaker 14, a displacement sensor 15, a T-shaped rod 16, a first spring 17, a first ash baffle 18, an ash box 19, a slot 20, a second ash baffle 21, a second spring 22, an air intake pipe 23, an air intake elbow 24, a filter plate 25, an ash discharge cover 26, an air pump 27, a filter box 28, a box cover 29, a sliding groove 30 and a dust filter plate 31.

[0019] Traditional arm-type hydraulic breakers have exposed many limitations in long-term use. For example, problems such as insufficient positioning accuracy, low operating efficiency, and low degree of automation are becoming increasingly prominent. In addition, when pneumatically crushing ore blocks, dust is generated during the crushing. The dust is easily adsorbed on the transmission components of the gantry truss, which can easily affect the accuracy of the crushing device.

[0020] It should be noted that the upper sides of the first gear 5 and the second gear 9 are tightly fitted with the upper inner side of the ash box 19. When the pneumatic crushing mechanism 14 is working, the first gear 5 and the second gear 9 will always be engaged with the tooth plate 4 and will not affect the movement of the pneumatic crushing mechanism 14. In addition, a column 2 is provided on the upper side of the grille 1, a crossbeam 3 is provided on the upper side of the column 2, an ash box 19 is provided on the upper side of the crossbeam 3, and an air intake pipe 23 is provided on the inner side of the column 2, and the column 2 is symmetrical about the vertical center axis of the grille 1. The columns 2 are fixedly connected to each other by a cross bar, and the connection is relatively stable, which is convenient for pneumatic crushing of ore blocks.

[0021] Working principle: When using the fully automatic gantry truss pneumatic crushing device, Figure 1 and Figure 3 As shown, a tooth plate 4 is provided on the upper side of the beam 3, and the tooth plate 4 is meshed with the first gear 5. Since a connecting block 8 and a second gear 9 are provided on the upper side of the connecting plate 7, and the second gear 9 is meshed with the tooth plate 4, the connecting plate 7 is connected to the tooth plate 4 through the first gear 5, the first motor 6, the connecting block 8 and the second gear 9, so that the connecting plate 7 can move forward and backward smoothly. Starting the first motor 6 will cause the first gear 5 to rotate, and the rotating first gear 5 will cause the first motor 6 to move with the connecting plate 7.

[0022] like Figure 3 and Figure 4 As shown, the lower side of the connecting plate 7 is fixedly connected to the second motor 10 through the ear plate, and the output shaft of the second motor 10 is fixedly connected to the threaded rod 11, and the threaded rod 11 is rotatably connected to the ear plate on the lower side of the connecting plate 7. When the second motor 10 is started, the second motor 10 will rotate the threaded rod 11. Since the threaded rod 11 is threadedly connected to the moving block 12, and the moving block 12 is slidingly connected to the limit rod 13, the rotating threaded rod 11 will move the pneumatic crushing mechanism 14 through the moving block 12, making it convenient for the pneumatic crushing mechanism 14 to move left and right, and the ore block is placed on the upper side of the grid 1, and the pneumatic crushing mechanism 14 is started, so as to facilitate the crushing of the ore.

[0023] In addition, the use of machine vision to accurately analyze the size of the ore and cooperate with spatial modeling to realize dynamic planning of the crushing path can greatly improve the speed and accuracy of the crushing device, so that the crushing device can quickly and accurately locate the ore on the grid 1, greatly improving the crushing efficiency of the crushing device. The displacement sensor 15 forms real-time communication with the closed-loop control to ensure that the pneumatic crushing mechanism 14 can accurately crush the ore blocks.

[0024] like Figure 1 and Figure 7As shown, the upper side of the beam 3 is slidably connected with a T-shaped rod 16, and a first dust baffle 18 is provided on the upper side of the T-shaped rod 16, and a first spring 17 is provided on the outer side of the T-shaped rod 16. The elastic potential energy of the first spring 17 can allow the first dust baffle 18 to move upward, and an dust box 19 is provided on the upper side of the beam 3, and a slot 20 is provided on the inner side of the dust box 19. The second dust baffle 21 is slidably connected to the inside of the slot 20. At this time, the first dust baffle 18 and the second dust baffle 21 perform a preliminary seal on the opening on the side of the dust box 19, reducing dust from entering the inner side of the beam 3 and the dust box 19, preventing dust from falling on the upper side of the tooth plate 4, and facilitating the movement of the connecting plate 7.

[0025] In addition, a second spring 22 is provided on the upper side of the second dust baffle 21. When the first gear 5 or the second gear 9 moves, the connecting shaft of the first gear 5 or the second gear 9 will contact the side surfaces of the first dust baffle 18 and the second dust baffle 21. Since the side surfaces of the first dust baffle 18 and the second dust baffle 21 are arc-shaped, the connecting shaft of the first gear 5 or the second gear 9 will squeeze the side surfaces of the first dust baffle 18 and the second dust baffle 21. The first dust baffle 18 will move down, and the second dust baffle 21 will move up. At this time, the first spring 17 on the outside of the T-bar 16 and the second spring 22 on the upper side of the second dust baffle 21 will both undergo elastic deformation and will not hinder the first gear 5 or the second gear 9; and when the connecting plate 7 continues to move, the first dust baffle 18 and the second dust baffle 21 next to it will also undergo the same movement.

[0026] When the first gear 5 or the second gear 9 is no longer tightly fitted with the first ash baffle 18 and the second ash baffle 21, the first spring 17 and the second spring 22 will restore their elastic deformation. At this time, the first ash baffle 18 and the second ash baffle 21 will move up and down respectively until the upper side of the first ash baffle 18 is tightly fitted with the lower side of the second ash baffle 21. Therefore, the side of the beam 3 and the ash box 19 will form a relatively sealed environment, reducing dust from drifting to the upper side of the tooth plate 4, thereby facilitating the movement of the pneumatic crushing mechanism 14, which is beneficial to crushing the ore.

[0027] like Figure 2 Figure 4 and Figure 6As shown, the pneumatic crushing mechanism 14 starts the suction pump 27 when working, and the suction pump 27 will extract the air in the suction pipe 23 through the air supply pipe. At this time, the suction elbow 24 on the lower side of the suction pipe 23 will extract the air on the upper side of the grille 1. Since the suction elbow 24 is set in an "S" shape, the extracted air will be transported to the suction elbow 24, and a filter plate 25 is provided on the inner side of the suction elbow 24. The filter plate 25 can prevent large particles of debris from entering the suction pump 27 through the air supply pipe, making it convenient to extract dust-containing air for processing. In addition, the lower side of the suction elbow 24 is threadedly connected with a dust discharge cover 26. The large debris filtered by the filter plate 25 will fall on the lower side of the suction elbow 24. The debris can be cleaned by removing the dust discharge cover 26.

[0028] like Figure 2 and Figure 5 As shown, a sliding groove 30 is provided inside the filter box 28, and a dust filter plate 31 is slidably connected to the inner side of the sliding groove 30. The air extracted by the vacuum pump 27 will be transported to the filter box 28. The dust filter plate 31 can filter the extracted air to prevent dust from entering the atmosphere again, thereby reducing the dust in the air. In addition, the side of the filter box 28 is rotatably connected to a box cover 29. By opening the box cover 29, the dust filter plate 31 can be slid and removed from the sliding groove 30, making it convenient for air to be discharged from the filter box 28.

[0029] This is the entire working process of the fully automatic gantry truss type pneumatic crushing device. Contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.
