[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0023] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0024] Embodiment 1:
[0025] Combination Figure 1-3 As shown, this embodiment provides a vertical mill feeding valve, including: a main body module 100 and a feeding module 200.
[0026] Among them, the main body module 100 includes a tube body 110, a feed pipe 120 fixed at the top end of the tube body 110, a discharge pipe 130 fixed at the bottom end of the tube body 110, a first side plate 140 fixed on one side of the tube body 110, a motor 150 installed on the first side plate 140 and with its shaft extending into the inner cavity of the tube body 110, and a cross shaft 160 fixed on the shaft of the motor 150.
[0027] The tube body 110 is used to install other components. The feed pipe 120 is connected to the inner cavity of the tube body 110 and is used to deliver materials into the inner cavity of the tube body 110. The discharge pipe 130 is connected to the inner cavity of the tube body 110 and is used to deliver materials in the tube body 110.
[0028] The first side plate 140 is fixed on the tube body 110 and is used for installing the motor 150. The shaft of the motor 150 extends into the inner cavity of the tube body 110 to drive the feeding module 200 to rotate. The cross shaft 160 is fixed on the end of the shaft of the motor 150 and is used to engage with the feeding module 200 to facilitate the motor 150 to drive the feeding module 200 to rotate.
[0029] The feeding module 200 includes a fixing seat 210 symmetrically fixed on both sides of the tube body 110, an electric telescopic rod 220 installed on the fixing seat 210, a second side plate 230 fixed on the end of the electric telescopic rod 220, a valve shaft 240 with one end rotatably mounted on the second side plate 230 and the other end extending into the tube body 110, a guide rail 250 arranged in an annular array on the valve shaft 240, a limit plate 260 fixed on the valve shaft 240 in an annular array, a valve plate 270 with both ends embedded in the guide rail 250, and a bolt 280 passing through the limit plate 260 and the valve plate 270.
[0030] The fixing seat 210 is used to install the electric telescopic rod 220 to maintain the stability of the electric telescopic rod 220. The end of the electric telescopic rod 220 is fixedly connected to the second side plate 230 to drive the second side plate 230 to move. In addition, the length of the electric telescopic rod 220 when fully extended is twice the length of the tube body 110, which facilitates the feeding module 200 to be completely moved out of the tube body 110.
[0031] The second side plate 230 is used to install the valve shaft 240 to maintain the stability of the rotation of the valve shaft 240. One end of the valve shaft 240 is rotatably installed on the second side plate 230, and the other end extends into the inner cavity of the tube body 110 for installing the guide rail 250. A cross groove 241 is opened on the end of the valve shaft 240 extending into the tube body 110, and the cross shaft 160 and the cross groove 241 are interlocked, which makes it convenient for the motor 150 to drive the valve shaft 240 to rotate, and at the same time makes it convenient for the valve shaft 240 to be able to separate from the motor 150 shaft.
[0032] The guide rails 250 are symmetrically arranged to ensure the stability of the valve plate 270 . A slide groove is provided on the guide rails 250 , and both ends of the valve plate 270 are embedded in the slide groove to facilitate installation and removal of the valve plate 270 .
[0033] The limiting plates 260 are symmetrically arranged, and the distance between the limiting plates 260 is equal to the thickness of the valve plate 270. They are used to fix the valve plate 270. A circular hole 261 is opened on the limiting plate 260 on one side, and a threaded groove 262 is opened on the limiting plate 260 on the other side. At the same time, a through hole 271 is opened on the valve plate 270. The bolt 280 passes through the circular hole 261 on the limiting plate 260 on one side and engages with the through hole 271 on the valve plate 270 in the threaded groove 262 on the limiting plate 260 on the other side to fix the valve plate 270 and maintain the stability of the valve plate 270.
[0034] The valve plate 270 is used to rotate under the drive of the valve shaft 240. One side of the valve plate 270 is close to the valve shaft 240, and the other side is close to the inner wall of the tube body 110. At the same time, a material bin is formed between adjacent valve plates 270. When the valve shaft 240 drives the valve plate 270 to rotate, the material bin is driven to rotate, and the material fed into the feed pipe 120 is fed into the discharge pipe 130 to complete the feeding. When the valve shaft 240 stops rotating, the valve plate 270 does not move, blocking the discharge of the material.
[0035] Working principle and use process of the utility model: when in use, the material enters the tube body 110 through the feed pipe 120, at this time, the motor 150 drives the cross shaft 160 to rotate, the rotation of the cross shaft 160 drives the valve shaft 240 to rotate, the rotation of the valve shaft 240 drives the guide rail 250 to rotate, the rotation of the guide rail 250 drives the valve plate 270 to rotate, and feeding is performed. When the valve shaft 240 or the valve plate 270 needs to be maintained, the electric telescopic rod 220 is started to drive the second side plate 230 to move out, and the movement of the second side plate 230 drives the valve shaft 240 to move out of the tube body 110. At this time, the valve shaft 240 and the valve plate 270 can be maintained. Maintenance is performed. After the maintenance is completed, the electric telescopic rod 220 drives the second side plate 230 to retract, and the retraction of the second side plate 230 drives the valve shaft 240 to retract. At this time, the cross shaft 160 on the shaft of the motor 150 is embedded in the cross groove 241 of the valve shaft 240, so that the motor 150 can drive the valve shaft 240 to rotate. When the valve plate 270 is damaged and needs to be replaced, it is only necessary to unscrew the bolts 280, take out the damaged valve plate 270, and then replace the new valve plate 270, so that the two ends of the new valve plate 270 are embedded in the guide rail 250, and then the bolts 280 are passed through the limit plate 260 and screwed on the valve plate 270 to complete the replacement of the valve plate 270.
[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
