Description

Technical Field

[0001] The utility model relates to the technical field of pecan processing, in particular to a shell-kernel separation device for pecan processing. Background Art

[0002] Pecan is a plant of the Juglandaceae family and the genus Carya. Walnut kernels are rich in nutrients and are known as the world's famous "four major dried fruits" along with almonds, cashews, and hazelnuts. The kernels are delicious and edible, and can also be used to extract oil. The oil is fragrant and delicious, and can be eaten or used to prepare lacquer; the husk can be used to make activated carbon; the wood is tough and is a high-quality material. In order to facilitate people's consumption of walnuts and to increase sales through intensive processing of walnuts, factories generally separate the shells from the kernels.

[0003] After searching, for example, a shell-kernel separation device for pecan processing is disclosed in Chinese patent documents [Application number: CN202121954122.6]. This shell-kernel separation device for pecan processing includes a first support leg installed on the lower surface of the shell-kernel separation device, and there are four first support legs, a placement plate is provided on the shell-kernel separation device, a pressing plate is provided at the front end of the placement plate, pressure sensors are installed on both sides of the lower surface of the pressing plate, and there are two pressure sensors, a screening device is provided on one side of the shell-kernel separation device, a motor is installed on one end face of the shell-kernel separation device, a discharge port is provided on the other end face of the shell-kernel separation device, and a control device is provided on the front end face of the shell-kernel separation device.

[0004] When the device disclosed in the patent is used, the separated shell kernels can be further screened, so as to facilitate the subsequent processing of the shell kernels. However, when in use, the screening plate is driven to vibrate by a vibration motor, so as to improve the screening efficiency. However, although the vibration frequency of the vibration motor is high, the vibration amplitude is small, which leads to low efficiency in screening the shell kernels, affecting the subsequent use of the shell kernels.

[0005] At the same time, the inside of the shell kernel contains not only pecan debris produced during separation, but also the skin on the surface of the walnut kernel, which cannot be used later. The device cannot separate these useless things during screening, and the screening effect on the shell kernel is not good. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model uses a power mechanism to drive a cam to move the screening shell, and with the cooperation of a compression spring, the screening shell can be moved back and forth, thereby increasing the shaking amplitude of the screening shell and effectively improving the screening efficiency of the shell kernels.
