Description

A kind of macadamia nut cracking machine

technical field

The utility model relates to the technical field of nut shell breaking equipment, in particular to a macadamia nut shell breaking machine.

Background technique

Macadamia nuts have high nutritional value and are known as the "King of Dried Fruits". They are widely loved by people, but the shell of macadamia nuts is hard and difficult to break. There are two ways to break the shell and mechanically break the shell.

The method of manual shell breaking is mainly to use shell breaking pliers (such as a kind of macadamia nut shell breaking pliers disclosed in the Chinese utility model patent with the application number of 201420370566.9) to clamp or compress the nut shells one by one to make them broken. This shell breaking method is extremely efficient. Low, labor-intensive, only suitable for household use, can not meet the needs of processing enterprises.

Compared with manual shell breaking, mechanical shell breaking has greatly improved efficiency and low labor intensity, which is suitable for the development of processing enterprises. Mechanical shell breaking mainly includes impact crushing and squeezing saw pins.

The way of impact crushing is to drive the hammer to crush the fixed nuts through the operation of the machine. For details, please refer to the nut crusher disclosed in the Chinese invention patent with the application number 201310672237.X, and the Chinese invention with the application number 201210416458.6 The stamping type macadamia nut shell breaking machine disclosed in the patent. In the actual use process, because the impact force is not easy to grasp, and also affected by the hardness of the nut shell itself, the probability of one-time cracking is low, and multiple crushing operations are often required, resulting in Low production efficiency. At the same time, due to multiple crushing operations and the influence of the impact position, the nuts are easily damaged while the shells are broken, and the rate of broken kernels is high, which increases the processing cost of the enterprise.

The way of extruding the saw pin is to cut the shell of the nut with a high-speed saw blade and then crush the shell by extrusion. For example, the Chinese invention patent with application number 201210325202.4 discloses an extrusion sawing type macadamia nut shelling machine. Including silo, rotary quantitative feeding mechanism, material guiding mechanism, comprehensive mechanism of sawing grooving and extrusion shell breaking, pressure adjustment mechanism of curved arc tooth directional groove, discharge hopper, transmission system, power mechanism, frame, gear The speed change mechanism and the safety shield are partly composed. Among them, the power mechanism is divided into two groups to transmit power to the sawing slotting and extrusion shell breaking comprehensive mechanism. The central shaft drives the saw blade to rotate at a high speed, and at the same time transmits the power to the transmission system; Through the transmission system, the power is transmitted to the sawing grooving and extrusion shell breaking comprehensive mechanism for low-speed rotation of the two toothed discs along the axis of the central axis, and at the same time, the power is transmitted to the gear transmission mechanism to realize the uniform rotation of the rotary quantitative feeding mechanism. ; Nuts enter the rotary quantitative feeding mechanism from the silo, then enter the material guiding mechanism, and then enter the comprehensive mechanism of sawing, grooving and extruding shell breaking; Strict fixed-ratio transmission realizes the synchronous matching of feeding and cracking; the quantitative feeding turntable outputs a nut to the material guide groove every time it rotates one revolution. The extruding and sawing macadamia nut shelling machine can better ensure the integrity of the nuts, but the equipment still needs nuts with good shape consistency to achieve the ideal shelling effect, otherwise there will be some sawing failures. The problem of opening or squeezing is not broken, and the yield rate of finished products after one-time processing is poor.
