Ensiling machine cutter clearance adjusting and automatic sharpening device

Abstract

The invention discloses an ensiling machine cutter clearance adjusting and automatic sharpening device which comprises a clearance adjusting mechanism and an automatic sharpening mechanism. The clearance adjusting mechanism is provided with a fixed blade feeding electric push cylinder, a stay-wire displacement sensor, a stress sensor and a vibration sensor, and a controller controls working of thefixed blade feeding electric push cylinder; the automatic sharpening mechanism is provided with an electro-hydraulic push rod and a sharpening driving electric push cylinder, the driving end of the electro-hydraulic push rod is connected with fixed sharpening stone, the electro-hydraulic push rod pushes the sharpening stone to be close to or away from a movable blade, and the sharpening driving electric push cylinder drives the sharpening stone to be in reciprocating motion along the length direction of the movable blade; the automatic sharpening mechanism is provided with a displacement sensor for monitoring motion of the electro-hydraulic push rod, and the displacement sensor is mounted in hydraulic oil inside the electric push hydraulic cylinder. A clearance between the movable blade and the fixed blade can be adjusted automatically, the sharpening mechanism is controlled by the automatic sharpening system to complete grinding of the movable blade, and cutting-up effect is ensured.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a silage machine cutter gap adjustment and automatic sharpening device. Background technique [0002] With the improvement of Chinese residents' living standards, people's requirements for food are developing from being full to eating well, and domestic animal husbandry has developed rapidly. [0003] In the past, corn stalks were mostly used for fire cooking or directly burned in the field, which made the utilization rate of straw resources low and caused some pollution to the environment. With the country's concern about environmental pollution, relevant policies have been formulated to prohibit straw burning. This will guide the development of straw resources to the direction of efficient utilization. [0004] The fast-growing animal husbandry urgently needs these fresh stalks as feed for livestock, and crushing and recycling corn stalks for animal husbandry can not only solve the so...

Problems solved by technology

The operator shakes the crank handle to make the screw rotate and drive the screw nut to move left and right, so that the knife sharpening box is driven to reciprocate along the guide groove through the guide slider, which avoids removing the moving knife for grinding after the farm tool is operated. However, it is suitable for small machines, and at the same time, the handle is manually shaken to make the whetstone reciprocating, and the operation efficiency is low
