Rapidly returning device for roll crusher

Abstract

The invention relates to a rapidly returning device for a roll crusher. The rapidly returning device comprises a base, a fixed bearing block and a slidable bearing block are parallelly arranged on the base, a frame type sliding seat is arranged on the outer side of the slidable bearing block and comprises a connecting arm, a vertical support plate and a T-shaped sliding way, one end of the connecting arm is fixedly connected with the top end of the vertical support plate, the other end of the connecting arm is fixedly connected with the top end of the fixed bearing block, the T-shaped sliding way is fixed on the base, the bottom of the slidable bearing block is connected with the T-shaped sliding way through a T-shaped sliding rail, the top of the slidable bearing block is connected with the connecting arm through a roll ball, and an elastic restoring mechanism is arranged on the vertical support plate. The rapidly returning device is simple in structure and convenient to assemble and can automatically and rapidly return and rapidly reset when meeting hard substances, gaps between tooth rollers can be rapidly and reliably adjusted, and continuous and stable operation of the roll crusher is ensured.

Description

technical field [0001] The invention relates to a protection device for a roller crusher, in particular to a flashback device for a roller crusher. Background technique [0002] Roller crushers are suitable for crushing medium-hard materials in industrial sectors such as cement, chemical industry, electric power, metallurgy, building materials, and refractory materials, such as secondary and fine crushing of limestone, slag, coke, coal, etc. The roller crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. The early roller crushers had no back-off protection device on the toothed rollers. Once the materials contained hard-to-break substances, such as iron blocks, the roller crushers were easily damaged. Chinese patent ZL201120473095.0 discloses a roll crusher retreat protection device, which includes a bearing seat that can slide back and forth on the slide rail. The slide rail is fixed on the frame and is divide...

Problems solved by technology

However, the roller crusher used for crushing crops (green fodder), such as corn, wheat and other crops for secondary crushing, may have excessive material feeding or hard objects entering the roller crusher during the working process. If the toothed roller No flash back, easy to cause material blockage or tooth roller damage
