[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a cylinder ejection type insert silo of the utility model in conjunction with the accompanying drawings.

[0019] like Figure 1 Figure 2 As shown, a cylinder ejection type insert silo of the utility model comprises a silo 1, a discharge hopper 2, a lifting plate 3, a lifting device 4 and a fixing device 5. The discharge hopper 2 and the lifting device 4 are fixedly mounted on the fixing device 5. The discharge hopper 2 is fixed at the outlet of the silo 1, and the outlet of the discharge hopper 2 is aligned with the vibration plate. The upper end of the lifting plate 3 extends into the discharge hopper 2 from the lower end of the discharge hopper 2, and the lower end of the lifting plate 3 is connected to the lifting device 4, and the lifting device 4 controls the lifting of the lifting plate 3. A photoelectric sensor 21 is provided on the discharge hopper 2, and the photoelectric sensor 21 is used to identify the material in the vibration plate. The photoelectric sensor 21 is electrically connected to the control system, and the control system is electrically connected to the lifting device 4. When the photoelectric sensor 21 sends a material shortage signal, the control system receives the signal and controls the lifting device 4 to work, and ejects the lifting plate 3, and the insert in the silo 1 will be ejected out of the discharge hopper 2.

[0020] The fixing device 5 includes a silo fixing mechanism 51, a complete machine mounting mechanism 52, and a lifting device mounting plate 53. The silo fixing mechanism 51 is fixedly mounted on the complete machine mounting mechanism 52 and is used to fix the discharge hopper 2. The complete machine mounting mechanism 52 is fixedly mounted on the lifting device mounting plate 53 and is used to support the silo fixing mechanism 51. The lifting device mounting plate 53 is used to install the lifting device 4.

[0021] The silo fixing mechanism 51 includes a silo fixing plate 511 and a support shaft 1 512. The discharge hopper 2 is fixedly mounted on the silo fixing plate 511. The support shaft 1 512 includes multiple shafts for supporting the silo fixing plate 511 and the discharge hopper 2 above. The upper end of the support shaft 1 512 is fixedly mounted on the lower surface of the corner of the silo fixing plate 511, and the lower end is fixedly connected to the whole machine mounting mechanism 52. The bottom of the silo fixing plate 511 has a channel for the lifting plate 3 to pass through. The area of ​​the channel is the same as the cross-sectional area of ​​the lifting plate 3 to ensure the dynamic sealing of the bottom of the silo fixing plate 511 during the lifting process of the lifting plate 3.

[0022] The whole machine installation mechanism 52 includes a whole machine installation plate 521 and a second support shaft 522. The lower end of the first support shaft 512 is fixedly connected to the corner of the upper surface of the whole machine installation plate 521.

The upper end of the second support shaft 522 is fixedly installed on the lower surface of the corner of the whole machine installation plate 521, and the lower end is fixedly connected to the corner of the jacking device installation plate 53. The whole machine installation plate 521 has a hollow area in the middle for the jacking plate 3 to pass through. The area of ​​the hollow area is larger than the cross-sectional area of ​​the jacking plate 3 to facilitate the unobstructed passage of the jacking plate 3.

[0023] The jacking device 4 is mounted on the jacking device mounting plate 53. The jacking device 4 includes an intermediate transition plate 41, an oil pressure buffer 42, a linear motion mechanism 43 and a driving mechanism 44. The intermediate transition plate 41 is fixedly mounted on the bottom of the jacking plate 3 to provide support and stability during the jacking process. The oil pressure buffer 42 is mounted on the intermediate transition plate 41. The jacking device mounting plate 53 has a through hole for the oil pressure buffer 42 to pass through at the position aligned with the oil pressure buffer 42. The oil pressure buffer 42 is used to provide buffering during the jacking process. The linear motion mechanism 43 includes a linear bearing 431 and a guide shaft 432. There are at least two linear bearings 431, which are symmetrically arranged on the jacking device mounting plate 53. The number of guide shafts 432 matches the number of linear bearings 431. The upper end of the guide shaft 432 is fixedly connected to the bottom of the intermediate transition plate 41, and the lower end passes through the linear bearing 431. During the lifting and lowering process of the jacking plate 3, the guide shaft 432 slides up and down in the linear bearing 431 to limit the circumferential position of the jacking plate 3 from changing. The driving mechanism 44 includes a cylinder mounting seat 441, a cylinder 442 and a cylinder joint 443. The cylinder mounting seat 441 is fixedly mounted at the middle position of the bottom of the jacking device mounting plate 53. The cylinder 442 is fixedly mounted on the cylinder mounting seat 441. The jacking device mounting plate 53 has a through hole for the cylinder joint 443 to pass through. One end of the cylinder joint 443 is fixedly connected to the cylinder 442, and the other end passes through the jacking device mounting plate 53 and is fixedly connected to the bottom center of the intermediate transition plate 41.

[0024] During production and use, the utility model is used in conjunction with a vibration plate, and the discharge hopper 2 faces the vibration plate to ensure that the inserts coming out of the discharge hopper can accurately fall into the vibration plate. When the inserts in the silo are used less and less and fall to the position of the photoelectric sensor 21 of the silo, the photoelectric sensor 21 will send a material shortage information to the control system, reminding the need to refill the silo. When the photoelectric sensor 21 sends a material shortage signal, the control system receives the signal and controls the cylinder 442 to operate. When the cylinder 442 rises, it will lift up the insert on the lifting plate 3. Since the end of the lifting plate 3 has a certain inclination angle, when the cylinder rises to the end, the insert will roll out through the discharge hopper 2 and fall into the vibration plate. At this time, the cylinder 442 retracts to its original position. If the utility model continues to receive a material shortage signal from the vibration plate, the cylinder 443 will repeat the above action.
