Detailed Description

The following describes the present invention in further detail with reference to the accompanying fig. 1-3.

A Chinese chestnut huller comprises a rack 1, a motor 2 located below the rack 1, a hulling cylinder 3 located above the rack 1 and provided with a feed inlet 4, a hulling component arranged in the hulling cylinder 3 and connected with the motor 2 through a first belt 11, a plurality of hollow deformed steel screws 8 arranged between the lower surface of the hulling cylinder 3 and used for extruding and hulling Chinese chestnuts in cooperation with the hulling component, two conveyor belt wheels 9 located below the hulling cylinder 3 and horizontally arranged correspondingly, one conveyor belt wheel 9 connected with the hulling component through a second belt 17, a conveyor belt 12 connected between the two conveyor belt wheels 9, and a blower 10 located on one output side of the conveyor belt 12 and connected with the motor 2 through a third belt 18.

The stripping assembly comprises an elastic extrusion container 6 with a plurality of bosses 16 uniformly distributed on the surface, and a driving assembly for driving the elastic extrusion container 6 to rotate, wherein the elastic extrusion container 6 is preferably made of rubber with certain density. The elastic extrusion cylinder 6 with the bosses 16 has a larger contact area with the chestnuts in the rotating and extruding process, the shelling chips can ensure that most of the chestnuts move along with the shelling chips under the stirring of the shelling chips instead of being extruded, so that the shelling efficiency is greatly reduced, meanwhile, the elastic extrusion cylinder can prevent the chestnuts from being crushed due to the overlarge local stress of the chestnuts, a large number of bosses 16 are rolled and extruded along with the elastic extrusion cylinder 6, the extrusion times of the chestnuts in unit time are increased, the chestnuts are fully shelled, and the shelling efficiency is improved; the elastic extrusion cylinder 6 is made of rubber with a certain density, has a certain elasticity during extrusion, and avoids rigid extrusion from damaging the Chinese chestnut kernels.

The driving assembly comprises a rotating shaft 5 connected with the motor 2 through a first belt 11, and tensioning devices distributed circumferentially around the outer surface of the rotating shaft 5 and used for tensioning the elastic extrusion cylinder 6, wherein each tensioning device comprises a cavity 14 with a pressing end 15, and a spring 13 acting on the pressing end 15 is arranged in the cavity 14. The spring 13 is arranged in the tensioning device, so that the tensioning device has certain elasticity, and the chestnut kernels are prevented from being damaged by rigid extrusion in the extrusion process; the spring 13 of the tensioning device is arranged in the cavity 14, and plays a role in guiding the spring 13, so that radial force is prevented from acting on the spring 13 in the extrusion process, and the spring 13 is prevented from being bent and deformed.

The center of pivot 5 is located 3 central vertical lines of taking off feed inlet 4 one sides of keeping away from of feed cylinder, and the eccentricity of pivot 5 for the distance between elastic extrusion tube 6 and the screw-thread steel 8 is different, and from feed inlet 4 one side, the distance between elastic extrusion tube 6 and the screw-thread steel 8 reduces gradually. When the Chinese chestnut is large in size, the Chinese chestnut can be squeezed and shelled at the large-size end with a relatively large distance between the Chinese chestnut and the large-size end, and the Chinese chestnut falls onto the conveyor belt 12 through the hollow part between the deformed steel bars 8; when the chestnut is small in size, the chestnut slides to the bottom end of the shelling cylinder 3, and if the extrusion force of the lug boss 16 on the elastic extrusion cylinder 6 is insufficient to shell the chestnut, the lug boss transfers the chestnut with small size to the small-size extrusion end with small distance between the elastic extrusion cylinder 6 and the deformed steel bar 8 in the rotating process, so that the chestnut is extruded and shelled.

When the motor 2 is started, the motor 2 drives the material removing component and the air blower 10 to operate through the first belt 11 and the third belt 18 respectively, and simultaneously drives the conveyor belt wheel 9 connected with the material removing component through the second belt 17 to rotate, and the conveyor belt wheel 9 drives the conveyor belt 12 to rotate. After the Chinese chestnut is put into the shelling cylinder 3 and shelled, the Chinese chestnut shell and the Chinese chestnut rice fall onto the conveying belt 12 through the hollow part between the deformed steel bars 8 and move to one end of the air blower 10 along with the conveying belt 12, and when the Chinese chestnut shell and the Chinese chestnut rice fall, the falling Chinese chestnut shell and the Chinese chestnut rice are separated by the wind generated by the air blower 10 due to different masses of the Chinese chestnut shell and the Chinese chestnut rice and different stresses when the Chinese chestnut shell and the Chinese chestnut rice are acted by the wind.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
