Abstract

The invention discloses a tiller adjustable in tilling depth. The tiller comprises an underframe, a case is fixedly connected to the left side of the bottom of the underframe, a gearbox is fixedly connected to the top of the case, a motor is fixedly connected to the right side of an inner cavity of the gearbox, and an output shaft of the motor is fixedly connected with a driving gear. The top andbottom of the case are movably connected with a reciprocating screw rod through bearings respectively, and the top of the reciprocating screw rod penetrates the case and extends into the inner cavityof the gearbox to fixedly connect with a driven gear. By the motor, the driving gear, the reciprocating screw rod, the driven gear and a screw block, a reciprocating device capable of moving up and down is formed jointly; by a supporting rod and tilling blades, a tilling device capable of turning the soil is formed jointly; by structural cooperation, tilling depth adjustability of the tiller is realized.

Description

technical field

[0001] The invention relates to the technical field of agricultural equipment, in particular to a tiller capable of adjusting the depth of tillage. Background technique

[0002] The tiller is a machine that uses a toothed ripper to loosen hard soil, frozen soil, old roads and even medium-hard rocks in earthwork construction. According to the connection form between the tiller and the tractor, there are two types: towed and suspended; provided by a tractor. The traction force and the weight of the ripper make the rake teeth cut into the soil and loosen the hard soil. After the machine passes through, the loose soil is left. It is often used for pre-digging operations before bulldozers or scrapers operate.

[0003] Existing tillers have fixed soil-turning depths, and cannot adjust the soil-turning depths according to the needs of the land and planting, which is very inconvenient in actual use. Contents of the invention
