Description

Technical Field

[0001] The utility model relates to the technical field of fixing components, in particular to a cutter fixing component of a crushing grid machine. Background Art

[0002] The crushing type screen can crush wood chips, empty bottles, cloth pieces and other debris in the sewage pipe network to protect other equipment in the pumping station and enable it to operate normally. It can be called the guardian angel of the pumping station. Therefore, crushing type screens with different gaps are required for different pumping stations.

[0003] The existing public patent (publication number CN216137365U) discloses CN216137365U. The motor drives the rotating shaft and the rotating drum to rotate. The upper ends of the rotating shaft and the rotating drum and the motor are connected by a coupling. The debris falls onto the cutter and the rotating drum. The rotating drum rotates to move the debris to the cutter. The rotating shaft drives the cutter to rotate and crush the debris. When it is necessary to scrape off the debris contained in the cutter, the mounting shaft is rotated to make the scraper on the mounting frame contact the debris contained in the cutter. The motor is started to rotate the rotating shaft to scrape off the debris contained in the cutter. The distance between the rotating drum and the rotating shaft is adjusted by the adjustment unit.

[0004] However, the existing blade is clamped and fixed by squeezing the upper and lower end shells against each other. However, during high-speed rotation, the end shells will vibrate, causing the blade to be squeezed and loose, affecting the stability of the blade fixation. Utility Model Content

Example 2

[0023] In addition to all the technical features of Example 1, the present embodiment further includes a limiting plate 204. A spacer ring 202 is provided on the upper end of the blade 201. A limiting groove 203 is provided in the center of the blade 201 and the spacer ring 202. The limiting plate 204 is installed on the outer wall of the drive shaft 1. The blade 201 is inserted onto the outside of the drive shaft 1 so that the limiting groove 203 provided on the inner side of the blade 201 is aligned with the limiting plate 204 provided on the outside of the drive shaft 1. The blade 201 is limited by the limiting plate 204 to avoid relative rotation with the drive shaft 1. The spacer ring 202 is then inserted onto the upper side of the blade 201. The blade 201 and the spacer ring 202 are inserted onto the outside of the drive shaft 1 in this order.

[0024] Furthermore, the assembly mechanism also includes a first knob 209, which is installed on the outer wall of the screw ring 205 in front of the first screw 207.

[0025] Furthermore, the assembly mechanism further includes a vertical plate 309 , which is installed on both sides of the housing 301 , and the inner groove 302 is opened inside the upper end of the vertical plate 309 to facilitate the linkage operation of the clamping components.

[0026] Furthermore, a bottom groove 306 is opened on the outer side of the lower side of the inner groove 302, and a second screw 307 is installed in the bottom groove 306. A pressure plate 308 is mounted on the outer wall of the second screw 307. The second screw 307 engages and drives the pressure plate 308 to move downward stably in the bottom groove 306 to achieve a downward pressure reinforcement effect.

[0027] Working principle: When the blade 201 needs to be installed, the blade 201 is inserted on the outside of the drive shaft 1, so that the limiting groove 203 provided on the inner side of the blade 201 is aligned with the limiting plate 204 provided on the outside of the drive shaft 1, so that the blade 201 is limited by the limiting plate 204 to avoid relative rotation with the drive shaft 1, and then the spacer ring 202 is inserted on the upper side of the blade 201, and the blade 201 and the spacer ring 202 are inserted on the outside of the drive shaft 1 in sequence, and the screw ring 205 is sleeved on the outside of the threaded wall at the upper end of the drive shaft 1 through threaded engagement, and at the same time, the screw ring 205 squeezes the uppermost inserted blade 201 downwards, clamps the blade 201 on the outside of the drive shaft 1, and twists the first knob 209 to drive the first screw The rod 207 rotates, and the engagement drives the card plate 208 to move from the slide groove 206 toward the drive shaft 1. The card grooves set on the surface match the threads set on the outer wall of the upper end of the drive shaft 1, so that the screw ring 205 and the drive shaft 1 are relatively fastened. After the casing 301 is inserted into the top end of the drive shaft 1 and fixed, the second knob 304 is twisted to drive the first bevel gear 303 to rotate, and the engagement drives the second bevel gear 305 to rotate, driving the connected second screw rod 307 to rotate, and the engagement drives the pressure plate 308 to move vertically downward in the bottom groove 306. The rough surface of the pressure plate 308 is squeezed downward on the upper end of the spacer ring 202, thereby reinforcing the spacer ring 202 for the second time, thereby ensuring the reinforcement of the blade 201.
