Staggered-pliers-type hazel shell cracking machine

Abstract

The invention discloses a staggered-pliers-type hazel shell cracking machine consisting of a rack as well as a hazel feeding device, a hazel shell cracking device, a hazel discharging device and a power drive device arranged on the rack. The staggered-pliers-type hazel shell cracking machine is characterized in that a material taking turntable is combined with a feeding hopper and a cleaning brush to take hazels one by one, thereby effectively avoiding the phenomena of material feeding blockage and cracking repeatability; a cam is utilized to control a sliding extrusion arm to realize the staggered-pliers-type shell cracking between a sliding extrusion block and a fixed extrusion block, so that the shells of the hazels can be cracked efficiently and singly one by one, the stroke in the shell cracking process is controllable, and the damage rate of hazelnuts can be effectively reduced; an extrusion chamber is designed to simulate the hazel in shape and is not limited by the size of the hazel, so that the hazel is stressed uniformly, and the shell cracking effect is ensured; and the hazel shell cracking device is simple in structure and reliable in work mode and can be used for cracking the shells of other spherical or oval nut materials such as walnuts and almonds, thus being strong in transformation feasibility. The staggered-pliers-type hazel shell cracking machine is simple in structure, high in shell cracking efficiency, low in nut damage rate, reliable in work mode and convenient to promote and apply.

Description

technical field [0001] The invention relates to a nut shell breaking machine, in particular to a staggered pincer type hazelnut shell breaking machine, which belongs to the field of agricultural product processing machinery.

Problems solved by technology

Hazelnut is one of the four most popular nuts and has the reputation of "the king of nuts". However, its shell is relatively hard and difficult to crack. In the past, it was usually done manually by farmers, which not only has low efficiency and labor-intensive cracking large, and the nut damage rate is high, which hinders the further development of the hazelnut industry to a certain extent

[0003] The use of mechanical shell breaking can effectively reduce labor intensity and improve shell breaking efficiency. However, due to the hardness and size of hazelnuts, the existing shell breaking machines are still easy to cause damage to the nuts, resulting in economic losses.

For example, a Chinese patent application (patent) No. CN200810062249.X discloses a shell cracking machine, which adopts a percussion hammer type shell cracking method, which solves the problem that hazelnuts are easily separated in half when knocked due to sharp corners and cannot be achieved. Effective cracking of the shell, but there are also problems that the relative sliding between the nut and the hammer head is easy to cause the percussion position to be inappropriate, the percussion force is affected by the size of the fruit and is difficult to control, and the nut damage rate is still high.

Another example is a Chinese patent application (patent) No. CN88102234.9, which discloses a cracking machine for nuts. It adopts a hydraulic bag-type cracking method, which can evenly distribute multiple pressure points on the nut shell. The pressure is suitable for nuts of different volumes and shapes, and achieves uniform shell breaking, but its disadvantage is that the complexity of the machine is high, which will inevitably increase the initial economic investment and later maintenance costs, so this limits the above-mentioned nut shelling machinery.
