Embodiment Construction

[0062] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0063] combine figure 1 , Figure 18 As shown, the front of the support 1 is low and the rear is high, the angle between the entire cage-type grading screen body and the horizontal line is β (4°≤β≤6°), and the feed end is higher than the discharge end. A material receiving tray 19 may also be provided at the bottom of the support 1 .

[0064] combine figure 1 , Figure 17 As shown, the feeding hopper 2 is connected with the rear beam 42 of the support 1 .

[0065] Such as figure 1 As shown, the inner layer discharge hopper 16, the middle layer discharge hopper 17, and the outer layer discharge hopper 18 are welded on the discharge hopper fixing plate 15, and the discharge hopper fixing plate 15 is connected with the support 1. The inclination angle of the hopper fixing plate 15 is consistent with the inclination angle β of the cage-type grading si...

Abstract

The invention relates to a rotary cage-type walnut classifying screen which is high in classifying efficiency and classifying precision, small in occupied area and low in cost and is used for classifying walnuts. The rotary cage-type walnut classifying screen comprises a support. A cage-type classifying screen body is installed on the support and driven by a driving device to rotate. The driving device is installed on the support. One end of the cage-type classifying screen body serves as a feeding end, and the other end of the cage-type classifying screen body serves as a discharging end inclining towards the feeding end. The cage-type classifying screen body is composed of multiple layers of screening cages, the body of each layer of screening cage is composed of cage bars, the distance between every two adjacent cage bars of the innermost layer of screening cage is the largest, the distances are gradually decreased layer by layer, the distance between every two adjacent cage bars of the outermost layer of screening cage is the smallest, and the walnuts are classified by adjusting the distance between every two adjacent cage bars of each layer of screening cage. After fed into the cage-type classifying screen body, the walnuts with different sizes can be left in the screening cages of corresponding classes when the cage-type classifying screen body rotates and are discharged by discharging devices fixed to the support and located at the positions corresponding to the screening cages of the classes respectively.

Description

technical field [0001] The invention relates to equipment for grading and screening walnuts of different sizes, in particular to a rotary cage type walnut grading sieve. Background technique [0002] Walnuts are popular due to their rich nutritional value. With the development of the walnut industry, in the current large-scale production, walnuts often need to be shelled to extract kernels. In order to realize walnut mechanical shelling and kernel extraction, the existing walnut shelling machines adopt the commonly used principles of crushing, extrusion, and impact shelling methods to shell and extract kernels. One of the common characteristics of these walnut shelling machines is that within a certain gap Shell the walnuts. In order to improve efficiency, the walnut shelling device that appears now needs to put walnuts in batches for shelling and kernel extraction. Due to the irregular shape and size of walnuts, when walnuts are placed in batches, the walnuts that do not...
