[0019] See also Figure 1-Figure 5 The present embodiment provides a bagged cement grabbing device, which is mainly composed of a device body 1, a grabbing arm 11 and a grabbing tooth 19. The device body 1 is composed of a connecting assembly and a device main frame 7. The connecting assembly is used to connect with an external mechanical arm, and is mainly composed of a connecting rod 2, a trapezoidal plate 3, a fixed rotating member 5 and an H-shaped steel plate 6. Two trapezoidal plates 3 are symmetrically welded in the middle of the top surface of the H-shaped steel plate 6 and are located on the front and rear sides of the H-shaped steel plate 6. A circular hole 4 is opened in the upper part of the trapezoidal plate 3. The connecting rod 2 is cylindrical, and both ends of it are step structures. The diameter of the end of the connecting rod 2 is adapted to the diameter of the circular hole 4 on the upper part of the trapezoidal plate 3. After passing through the circular hole 4, the two ends of the connecting rod 2 are connected to the trapezoidal plate 3 through the fixed rotating member 5. The fixed rotating member 5 can adopt an elastic retaining ring or retaining ring for the shaft. The fixing method of the connecting rod 2 and the trapezoidal plate 3 can make it easier for the cylindrical connecting rod 2 and the external mechanical arm to turn when working, greatly improving the flexibility of the equipment.

[0020] The H-shaped steel plate 6 is horizontally welded to the top of the equipment main frame 7. The equipment main frame 7 is a rectangular frame structure. Reinforced webs 8 are welded at both ends of the equipment main frame 7. The plate surface of the reinforced webs 8 is parallel to the end surface of the equipment main frame 7. A reinforced opening plate 9 is welded to the bottom of the equipment main frame 7. The reinforced opening plate 9 is located between the two reinforced webs 8. The reinforced webs 8 are symmetrically welded and fixed to the inside of the equipment main frame 7 along the long side direction of the equipment main frame 7. The height of the reinforced webs 8 is adapted to the internal height dimension of the equipment main frame 7. The reinforced webs 8 ensure the firmness of the trapezoidal plate 3 and the H-shaped steel plate 6, and increase the durability of this part.

[0021] A fixed base 10 is symmetrically welded to the lower part of both ends of the front and rear of the equipment main frame 7. A pin 12 is installed on the outer side of the fixed base 10. Each pin 12 is hingedly connected to the inner end of the grabbing arm 11, which ensures the rotation flexibility of the grabbing arm 11 and increases the operability of the equipment. The grabbing arm 11 is L-shaped, and the outer end of the grabbing arm 11 is tilted downward. The grabbing arms 11 are symmetrically distributed on the long side of the equipment main frame 7. A driving rod 16 is provided between the two grabbing arms 11 along the short side of the equipment main frame 7. The driving rod 16 is made of a square tube, and the length of the driving rod 16 is adapted to the distance between the two grabbing arms 11 along the short side of the equipment main frame 7. A fixed U-shaped part 17 is installed on the side of the driving rod 16 close to the equipment main frame 7.

[0022] Mountain-shaped connectors 13 are symmetrically welded on the upper part of the two end faces of the main frame 7 of the equipment. The mountain-shaped connector 13 is hingedly connected to the cylinder body of the hydraulic cylinder 15 through a fixed pin 14. The opening size of the front end of the mountain-shaped connector 13 is adapted to the size of the fixed pin 14. The fixed U-shaped member 17 is hingedly connected to the end of the piston rod of the hydraulic cylinder 15 through an axle pin. The size of the fixed U-shaped member 17 is adapted to the size of the hydraulic cylinder 15. The connection between the fixed U-shaped member 17 and the hydraulic cylinder 15 is a rotatable connection, which ensures that the hydraulic cylinder 15 can be normally extended and retracted, thereby driving the grabbing arm 11 and its driven part, and further ensuring the normal operation of the entire mechanical equipment.

[0023] The outer ends of the two grabbing arms 9 on the same side are connected by a rectangular connecting plate 18, and the length of the connecting plate 18 is greater than the distance between the two grabbing arms 11 along the short side direction of the equipment main frame 7. An inverted L-shaped grabbing tooth 19 is fixedly mounted on the connecting plate 18, and a plurality of grabbing teeth 19 are evenly arranged along the length direction of the connecting plate 18, and the number and spacing of the grabbing teeth 19 are adapted to the length of the connecting plate 18.

[0024] When grabbing a bag of cement, the piston rod of the hydraulic cylinder 15 extends, and the piston rod drives the grabbing arm 11 to rotate around the pin 12 through the fixed U-shaped piece 17 and the driving rod 16. The two grabbing arms 11 are close to each other, and the grabbing teeth 19 of the grabbing arm 11 completely grab a bag of bagged cement. The cross section of the grabbing teeth 19 is small at the front and large at the back, which can ensure the success rate of grabbing bagged cement. The grabbing teeth 19 replace the hands of people, reduce the working time of people contacting bagged cement, improve the safety of manual handling, and ensure that people do not suffer from diseases caused by contacting cement.
