Chinese chestnut has a long planting history in China and is one of important economic species in China. Chinese chestnut is rich in nutrition, contains a large amount of starch, protein, fat, vitamins and other nutritional factors in the tissues, and is covered by the reputation of Qianguo king. According to the description of Chinese medical science spectra, chinese chestnut also has the effects of promoting blood circulation to remove blood stasis, nourishing the stomach and invigorating the spleen, and the like, so that in clinic, some Chinese chestnut chemical extracts can be used for treating symptoms such as regurgitation, diarrhea, hematochezia and wound, and the like.
The chestnut bract is composed of bract meat, thorn bundles, hairy antler and fruit stalks. The chestnut is wrapped in the ball bract, which mainly plays a role in protection.

As known from the basis of mechanical manufacturing process, the machine base 1 is generally cast or welded. The casting method is suitable for casting parts which are produced in medium and large quantities and have complex structures. The equipment has larger size and simpler basic structure, and in consideration of the production process and the manufacturing cost, the machine base 1 is formed by welding square steel of 40 multiplied by 5mm, and the welding has the characteristics of simple process, good connection performance, high structural strength, low labor intensity of workers and the like.

The two baffle plates are fixed on the machine base 1 by M5 screws so as to be convenient to disassemble and assemble during mechanical maintenance.
In order to ensure that the chestnuts and other materials on the screen surface can move along one direction, the screen surface is generally arranged at a certain included angle with the horizontal plane, and the included angle is the inclination angle of the screen surface. The size of the inclination angle of the screen surface influences the screening efficiency of the material. To some extent, the greater the angle of inclination, the faster the material moves on the screen surface and the more efficient the separation of the mixture. However, if the inclination angle is too large, the material moves faster, and the time for which the material stays on the screen surface is shorter, which may cause some material to separate from the screen surface before being screened, and thus the screening effect may be deteriorated. The smaller the inclination, the slower the speed of movement of the material on the screen surface and the longer the residence time on the screen surface, resulting in a less efficient separation of the mixture, but the better the screening effect. In general, a good screening effect can be obtained when the inclination angle of the screen surface is in the range of 0-15 degrees. Specifically, in the embodiment of the present application, the sieve surface of the separating net 312 of the first separating mechanism 31 is mainly used for separating bracts with larger sizes, and the bracts with smaller sizes and chestnuts are required to have sufficient time to pass through the grid and enter the first separating mechanism 31, so that the sieve surface inclination angle of the separating net 312 is not too large, and the chestnut bract peeling machine 100 is designed to have a sieve surface inclination angle of 5 °; the screen surface of the vibrating screen 321 mainly separates small-sized bracts and other light impurities by using the negative pressure of the air suction device 6, and the requirement on the separation efficiency is high, so that the inclination angle of the secondary vibrating screen surface is designed to be 10 degrees.
The amplitude of vibration is an important factor affecting the screening efficiency of the first and second separating mechanisms 31 and 32, and in general, the screening efficiency can be controlled by adjusting the amplitude of vibration of the vibrating screen. The larger the amplitude is, the less the sieve pore blocking phenomenon is, and the raw material layering during sieving is facilitated. However, if the vibration amplitude of the vibrating screen is too large, the structural requirements on the mechanical equipment are high, such as adding an anti-seismic structure or a buffer structure. Therefore, in combination with the growth characteristics (such as particle size and shape) of the chestnut, which is the material screened by the device, the amplitude of the screen 312 is set to be 8mm, and the amplitude of the vibrating screen 321 is set to be 10mm by referring to relevant data.
The vibration direction angle is an included angle between a vertical line below the screen surface and the vibration direction line on the lower side of the screen surface; when the screen surface is horizontal, the vibration direction angle is the included angle between one side of the screen surface discharge port and the vibration direction line. The vibration direction angle is the distance that affects the displacement of material on the screen surface in the direction of throw. The larger the vibration direction angle is, the shorter the throwing distance of the material particles is, the lower the speed is, the longer the staying time of the material particles on the surface of the vibration sieve is, and the better the sieving effect is; if the vibration direction angle is smaller, the displacement distance of the material in the throwing direction is increased, the speed is increased, the staying time of the material on the surface of the vibrating screen is shortened, and the screening effect is poorer. Specifically, in the present application, the vibration direction angle of the separation net 312 and the vibration screen 321 is in the range of 30 ° to 60 °, and the vibration direction angle is initially set to be 45 ° by combining the working condition and the design experience of the chestnut bract peeling machine 100 in the present application
The vibration frequency refers to the number of vibration cycles of the shaker screen per unit time. When the amplitude is smaller, the reciprocating times of the materials on the vibrating screen surface are reduced, and the screening effect is poorer. On the contrary, when the amplitude is larger, the reciprocating motion times of the materials on the vibrating screen surface in unit time are increased, so that the screening efficiency and the screening speed are improved. However, if the vibration frequency is too high, the service life of the mechanical device is also shortened. Therefore, in order to ensure that the chestnut bract peeling machine 100 has good use performance and safety performance, the vibration frequency omega of the separation net 312 and the vibration screen 321 is 52.35rad/min.
Considering that in the actual use process, the Chinese chestnut peeling machine needs to be moved, the bottom of the machine base is provided with a plurality of universal wheels b, the mobility of the Chinese chestnut peeling machine is increased due to the design of the universal wheels b, and the peeling task in a multi-point working occasion can be completed.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents made by the contents of the present specification and drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
