[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a large ecological stone grinding and feeding device includes a base 1, an extension arm 2 and a suction cup 3 provided on the extension arm 2, including a flip plate 5 rotatably provided at the end of the extension arm 2;

[0026] A hoisting mechanism 4 for driving the base 1 to move in a vertical direction;

[0027] An auxiliary disc 7 is slidably mounted on the extension arm 2 and has a winding roller 24 mounted thereon;

[0028] A driving plate 6 for driving the flip plate 5 to deflect is provided with a cable 61 wound up by a winding roller 24 .

[0029] Specifically, a driving motor for driving the hoisting mechanism 4 is provided on the base 1. The driving motor can be started by remote control, so that the base 1 drives the extension arm 2 to move in the vertical direction to reach a specified position.

[0030] Furthermore, the transmission plate 6 is slidably mounted on the extension arm 2, and the flip plate 5 is provided with teeth. The transmission plate 6 is a rack structure that meshes with the teeth. The suction cup 3 and the auxiliary plate 7 are adsorbed on the stone to be transported. Since the suction cup 3 is provided with a folded portion, the interior of the suction cup 3 is sucked into a negative pressure, causing the folded portions to fold over each other. Subsequently, the distance between the extension arm 2 and the surface of the stone is shortened, and the upper surface of the stone pushes the auxiliary plate 7 upward, thereby driving the winding roller 24 upward. The distance between the winding roller 24 and the transmission plate 6 is lengthened, causing the winding roller 24 to pull the cable 61. The cable 61 drives the transmission plate 6 to slide, thereby driving the flip plate 5 to deflect toward the side of the stone, fixing the side of the stone and further ensuring the stable lifting of large stones.

[0031] In the above technology, the stone pushes the auxiliary plate 7 to drive the winding roller 24 to move upward, thereby driving the flip plate 5 to deflect toward the side of the stone. The flip plate 5 stabilizes the stone from both sides, which further prevents thicker stones from falling off. The flip plate 5 can also protect the side of the stone to avoid collision with foreign objects during the lifting process.

[0032] As an embodiment further provided by the present invention, it also includes a transmission gear 21 that is rotatably arranged and keeps synchronous movement with the hoisting mechanism 4, and a clutch gear 23 that meshes with the transmission gear 21 is provided at the end of the winding roller 24.

[0033] Specifically, the auxiliary disc 7 has a position within its travel for meshing the clutch gear 23 and the transmission gear 21. The hoisting mechanism 4 is driven by a drive motor, whose output shaft moves synchronously with the transmission gear 21 via a drive belt 22. After the auxiliary disc 7 is pushed upward by the stone, the clutch gear 23 meshes with the transmission gear 21. This represents the auxiliary disc 7's working position. At this point, the transmission gear 21 is driven by the drive motor, rotating the clutch gear 23. The clutch gear 23 then rotates the winding roller 24 and winds up the cable 61, driving the transmission plate 6 toward the clutch gear 23, causing the flip plate 5 to deflect.

[0034] As another embodiment further provided by the present invention, a limiting plate 51 is provided at the end of the flip plate 5 , and the limiting plate 51 has a bent and contracted state.

[0035] Specifically, during the process of the flip plate 5 deflecting toward the side of the stone, the limit plate 51 is driven to resist the stone. Since the limit plate 51 is made of a deformable material, in the initial state, the limit plate 51 is in a contracted state. At this time, an angle is formed between the limit plates 51. During the process of the limit plate 51 and the stone resisting each other, the angle gradually increases, and the deformation potential energy of the limit plate 51 itself is applied to the stone, further playing a role in preventing slipping.

[0036] As another embodiment further provided by the present invention, a telescopic airbag 71 is provided on the auxiliary plate 7, and the telescopic airbag 71 maintains a predetermined height.

[0037] Specifically, the limit plate 51 is connected to the telescopic airbag 71. A connecting pipe 52 is provided between the limit plate 51 and the telescopic airbag 71. The telescopic airbag 71 can buffer the auxiliary plate 7, preventing vibration generated during the meshing of the clutch gear 23 and the transmission gear 21 from being transmitted to the stone.

[0038] After the auxiliary plate 7 is pushed upward by the stone, the clutch gear 23 meshes with the transmission gear 21, marking the auxiliary plate 7's working position. The transmission gear 21, driven by the drive motor, now rotates the clutch gear 23. The clutch gear 23 then rotates the reel 24 and winds up the cable 61, driving the transmission plate 6 toward the clutch gear 23, causing the flip plate 5 to deflect. As the flip plate 5 deflects toward the side of the stone, it pushes the limit plate 51 against the stone. As the limit plate 51 and the stone contact, the angle between them gradually increases, causing the limit plate 51 to begin expanding. The internal volume of the limit plate 51 increases, drawing suction from the connecting pipe 52 to the telescopic airbag 71, causing it to contract. Because the auxiliary plate 7 is adsorbed onto the upper surface of the stone, the contraction of the telescopic airbag 71 drives the clutch gear 23 downward and disengages from the transmission gear 21. At this point, the flip plate 5 stops rotating and remains in a position against the side of the stone, preventing continued deflection of the flip plate 5.

[0039] Working Principle: Suction cup 3 and auxiliary plate 7 are attached to the stone to be transported. Due to the pleated portion on suction cup 3, negative pressure is created inside suction cup 3, causing the pleated portion to fold together. Subsequently, the distance between extension arm 2 and the stone surface is shortened, and the stone's upper surface pushes auxiliary plate 7 upward. Clutch gear 23 meshes with transmission gear 21. Driven by the drive motor, transmission gear 21 rotates clutch gear 23, which in turn rotates take-up roller 24 and winds up cable 61, driving transmission plate 6 toward clutch gear 23 and causing flip plate 5 to deflect. During the deflection of the flip plate 5 toward the side of the stone, the limit plate 51 is driven to abut against the stone. During the abutment between the limit plate 51 and the stone, the angle gradually increases, causing the limit plate 51 to begin to unfold. The internal volume of the limit plate 51 increases and is sucked toward the telescopic airbag 71 through the connecting tube 52, causing the telescopic airbag 71 to shrink. Since the auxiliary plate 7 is adsorbed on the upper surface of the stone, the telescopic airbag 71 will drive the clutch gear 23 to move downward and disengage from the transmission gear 21 when it shrinks. At this time, the flip plate 5 stops rotating and remains in a state of supporting the side of the stone to prevent the flip plate 5 from continuing to deflect.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
