(54) МНОГОВАЛКШАЯ СТРУЖКОДРОБШША(54) MULTIFUNCTIONAL FRIENDSHIP

Изобретение относитс к устройсТвам дл измельчени и может быть использовано в машиностроении, например в котлостроении дл вторичной переработки стружки.The invention relates to shredding devices and can be used in mechanical engineering, for example, in boiler construction for recycling chips.

Наиболее близким к изобретению вл етс многовалкова стружкодробилка , содержаща корпус с установленными в нем на валах режуп№1ми звездочками, зубь которых расположены со смещением по винтовой xniнии , противорежущие горизонталышеи наклонные гребенки и приводы Г1 Т.The closest to the invention is a multi-roll chip breaker, comprising a housing with sprockets installed in it on the shafts with 1 sprockets, the teeth of which are offset with a helical screw, counter-inclined ridges and G1 T drives.

Недостатком данной конструкций стружкодробилки вл етс то, что попадание предметов , не подлежащих дроблению, например резцов, кре пежных болтов и др., под валки, в нижнюю часть камеры предварител)ного дроблени , приводит к длительньм просто м или поломке ротора дробилки. Дл извлечени предметов, не поддающихс дроблению, попавших под валки, в НИ5ХНЮЮ часть камерыThe disadvantage of this chip breaker design is that the entry of objects that are not subject to crushing, for example, incisors, mounting bolts, etc., to the rolls, into the lower part of the pre-crushing chamber, results in a simple or breakage of the crusher rotor. To remove objects that can not be crushed, fell under the rolls, in the fifth part of the camera

предварительного дроблени , требует- с частична разборка ротора струзэскодробилки .pre-crushing, requires partial disassembly of the rotor of the crusher.

Цель изобретени - повышение эксплуатационных возможностей стру кодробилкй за счет исключени поломки ротора дробилки при попадании недробимых предметов.The purpose of the invention is to increase the operational capabilities of a jet-breaker jet by eliminating breakage of the rotor of the crusher in contact with unbreakable objects.

Поставленна цель достигаетс тем, что в устройстве, содержащем корпус, The goal is achieved by the fact that in a device comprising a housing,

10 с установленными в нем на валах режущими звездочками, зубь которых расположены со смещением по винтовой линии, наклонные гребенки снабжены механизмом их вертикального переме15 щени , выполненным в виде жестко соединенной с гребецкой подпружиненной плиты, ось поворота которой кинематически св зана с приводом.10 with cutting stars installed in it on the shafts, the teeth of which are offset in a helical line, the inclined combs are equipped with a vertical movement mechanism made in the form of a spring-loaded plate rigidly connected to the rower, the axis of rotation of which is kinematically connected with the drive.

На фиг. 1 схематически изображена FIG. 1 is schematically depicted.

Claims

20 proposed chip breaker without drives and couplings; in fig. 2 is the same, front view, in FIG. 3 - the same, top view, (section A-A in Fig. 1. 3 Stru; the crusher has a body 1 with cutting stars 3 installed in foams on the shafts 2, the teeth of which are located with a screw line offset, and also horizontal controversy 4 and inclined combs 5. Meshdu with asterisks and combs, active crushing zones are created.The inclined combs are equipped with a mechanism 6 for their vertical movement, made in the form of: a spring-loaded plate 7, which has an axis of rotation 8 and is equipped with a p-olic 9, which contacts with with tongs 10 mounted on a shaft 11, which by means of bevel gears 12 and 13, shaft 14, gear wheels 15 and 16 and gearbox 17 obtains rotation from the engine 18. In the process of operation, the stringed crusher in case of hit of an uncrushable body by a wheel with asterisks 3 and a comb 5 the shaft 19 stops, while in the windings of the motor drive shaft 19 increases the current, which through the electrical circuit includes a motor 18. Rotation from the motor 18 through the gearbox 17, spur gears 15 and 16, the shaft 14 bevel gears 12 and 13 before with the shaft 11 with cams 10. The roller 9 mounted on the plate 7 is moved to the smallest radius of the profile of the cam 10, the plate 7 about the axis 8 -povorachivaets and comb 5 is omitted. When the rotation of the shaft 19 is turned on, the sprockets 3 push the indestructible body towards the chamber 1 along the bottom, after which the engine 18 and the cams 10 raise the roller 9 to its largest radius, while the plate 7 and the comb 5 move to the upper working position. Such chip breaker design is reliable in operation and gives a great economic effect. Claims of the invention of an ogolkovka chip breaker, comprising a housing with cutting sprockets mounted thereon on the shafts, the teeth of which are displaced along a helical line, opposing horizontal and inclined combs and drives, in order to increase the operating-potential capabilities, the inclined combs have an adjustment mechanism their vertical movement, made in the form of a spring-loaded plate rigidly connected to the comb, the axis of rotation of which is kinematically connected with the drive.
