Reasons for loud noise of peanut sheller

With the continuous development of peanut planting industry, peanut manual shelling can not meet the requirements of production. Manual shelling is not only easy to fatigue and injury, but also has low work efficiency. Therefore, the majority of farmers in flower production area urgently require machines to replace manual shelling. The birth of peanut shelling machine has changed this situation to a great extent, so that farmers in flower production areas do not have to use the original shelling method for shelling, which greatly reduces farmers' physical labor and improves the efficiency of peanut shelling.

However, it is inevitable that the equipment will have mechanical noise during operation. The sources of noise include the vibration and running friction sound of components such as frame, fan, rotor and vibrating screen,

Fan noise generation mechanism: when the fan rotates, the surrounding air flow generates eddy current, which disturbs the air, and the resonance between the fan itself and the wind protection ring produces noise.

Mechanism of mechanical noise bending machine part: it is mainly the knocking of the piston on the cylinder block. The fundamental reason is that there is a gap between them and the lateral force borne by the reciprocating piston changes in direction. Influencing factors: piston clearance; Offset of piston pin hole; Piston height; Number of piston rings; Cylinder liner thickness; Lubrication conditions, etc.

Hydraulic system is an important noise source of construction machinery. One of the main noise sources of the hydraulic system is the oil pump. The research shows that the noise characteristics of the hydraulic valve are mainly related to three factors: the type of valve, the flow direction of fluid in the valve and the pressure in the return chamber. These three factors largely determine the noise of the hydraulic valve. The collision and friction between the components of the hydraulic mechanism will produce more noise. Nowadays, hydraulic equipment is developing in the direction of high speed, high pressure and high power, so the noise is bound to increase accordingly.
