Description

Nut cracker

Technical Field

The utility model relates to the technical field of nut shelling, in particular to a nut sheller.

Background

Various household nut cracker sold in the market at present have various problems such as single function, complex structure, inconvenient use, high cost and the like.

The screw rotary extrusion consists of a rotary handle, a screw extrusion head and a fixed stress frame, wherein the screw and the stress frame are connected through threads, and the rotary handle is fixed on the other side of the extrusion head on the screw. When in use, the screw rod is driven to rotate and advance by rotating the rotary handle, and a certain pressure is generated between the screw rod and the fixed stress frame to crush the nut shells clamped in the middle. The disadvantage is that the screw rotation speed is slow, and the shells cannot be broken rapidly. Especially when nuts are of different sizes, adjusting the length of the screw can waste much time.

The lever extrusion adopts the lever principle, two levers are connected through a shaft, an extrusion head and nut fixing devices are arranged on the levers on two sides, and when the levers are closed by force, a certain pressure is generated between the extrusion head and the fixing devices to crush nut shells. The mechanical structure is relatively complex, the size and the length are larger, the operation is laborious, particularly the included angle of the lever is too large when the nut is very large, the operation is more laborious, and the nut is difficult to fix by the fixing device.

The spring force impact principle is that the impact head is driven by the spring force of the spring to impact the shell so as to crush the shell. When in use, the spring is stretched or compressed to accumulate certain energy, the spring is released instantaneously, and the spring drives the impact head to crash the fruit shell. The impact head has the defects that the size of the impact head is limited by the strength and the diameter of the spring, the strength is lacked when a large number of nuts are crushed, aiming is required to be learned firstly when a small number of nuts are crushed, and the impact head is inconvenient to use. And the service life is not long due to the influence of the quality of the metal material of the spring and the metal fatigue period.

In order to solve the defects, the nut shell breaking tool is multipurpose, simple in structure, convenient and quick to use and low in cost.
