Embodiment Construction
[0012] The position of the manual adjustment mechanism of the horizontal roller mill guide plate in the mill relative to the mill drum 12 and the mill roller 13 in the axial direction of the mill is as follows figure 2 shown, the arrangement in the circumferential direction is as follows Image 6 shown.
[0013] In this manual adjustment mechanism for the guide plate of the horizontal roller mill, the guide plate 10 is located in the cavity formed by the end seal 18 on the feed side, the end seal 19 on the discharge side and the grinding drum 12, and the end seal on the feed side 18 and the discharge side end seal 19 are fixed to the ground by other equipment, and their outer circumferences have a gap with the cylinder body 12. The lower end behind the guide plate 10 is hinged with the rotating shaft i-11 fixed on the support i-15 between the inner wall of the end seal 18 on the feed side and the inner wall of the end seal 19 on the discharge side. The front part of the swi...

A manual adjustment mechanism for a material guide plate of a horizontal roller mill, characterized in that the lower end of the material guide plate is hinged to the rotating shaft i fixed between the sealed inner walls of the grinding cylinder. The front portion of the swing arm is fixed to the upper end behind the material guide plate. The middle part of the swing arm is hinged with the rotating shaft ii fixed between the inner wall of the grinding drum seal. The afterbody of the swing arm is hinged with one end of the connecting rod through the pin shaft i. A stop block with an axial through hole and a radial recess in the middle is fixed on the outer wall of the end seal on the feed side. The screw rod passes through the axial through hole on the stop block and is connected with the nut in the radial recess in the middle part of the stop block. Evenly distributed holes are arranged on the outer circumference of the nut, and the manual driving rod is inserted into the holes. The side of the nut and the side of the stop block are provided with concentric holes and inserted into the positioning pin. The screw rod passes through the hole on the end seal of the feeding side and is hinged with the other end of the connecting rod through the pin shaft ii. It can realize the control of the grinding time or grinding times of materials in the mill. It has simple and reliable structure, low failure rate, low cost, convenient maintenance and repair, and wide adaptability.
Description
technical field [0001] The invention belongs to grinding equipment in mining, metallurgy and cement industries. Background technique [0002] At present, the material propelling device of horizontal roller mill mostly adopts the combined action of scraping device, material adjustment and propelling device to control the grinding time of material in the mill. Among them, the material adjustment and propulsion device is composed of electric actuators, 2 universal joint shafts, 2 commutators and material guide plates. This kind of transmission mechanism is complicated, the equipment is heavier, and the maintenance of personnel is extremely inconvenient. Multi-mechanism transmission, low cost performance, and easy to cause large angle error of the guide plate, inconvenient to control the grinding time of materials in the mill SUMMARY OF THE INVENTION [0003] In order to solve the problems existing in the above-mentioned prior art, the present invention proposes the followin...
