Description
Technical field
The utility model relates to a kind of crops threshing apparatus, relates to a kind of the friction type husker sheller specifically.
Background technology
At present, in the technology of disclosed corn threshing device, be divided into vertical or horizontal two kinds, but in the majority with horizontal thresher.The theory structure of no matter vertical or horizontal its basic general character, all adopt and have spirochetal rotation roll body and be installed on and decide in the cylinder, and utilize and decide the cylinder barrel, or the matched in clearance between the cage drum, by rotation roll body and cylinder corn ear is pushed with tangential force and to carry out threshing, thereby improved the threshing efficiency of corn preferably, substituted traditional handwork.However, because the scrambling of the shape of corn ear integral body, size, thresher rotation roll body is the continuous hurricane band that distributes in addition, corn ear is carried out continuous extruding, thereby when carrying out threshing, also caused the fragmentation of part iblet and corn bone, causing broken main cause is that extruding force is too concentrated; In addition, the installation site of cylinder and helical tooth rotation roll body is fixed, and is prone to the clogging of corn ear, has not only strengthened degree of crushing, but also has influenced the operate as normal of thresher.
The utility model content
The purpose of this utility model is to provide a kind of and utilizes the tangential friction between the friction body to carry out threshing, and can carry out gap adjustment according to the size of corn ear, makes its bone, the low the friction type corn off line of grain percentage of damage.
For achieving the above object; the technical solution of the utility model is finished like this: a kind of the friction type husker sheller; it has to be respectively equipped with to be interrupted on the inner surface of the outer surface of the rotation of original structure friction body and outer friction body and distributes and the projection of continuous distribution form, and between outer friction body that has hopper and blanking cavity setting in order to the slack adjuster of the body upper and lower displacement that rubs outside regulating.
Rotation friction body and the outer shape that rubs body related in the technical solution of the utility model can be cone or cylinder.
Described rotation friction body is the cartridge type or the mouse cage type structure body of a sealing.
The top of described rotation friction body can be parallel Closed End, or a tapered cap is set.
Projection on the described rotation friction body can be cylinder surperficial perpendicular or parallel setting with it.
Projection on the described outer friction body is a bus body or a vertical body in the shape of a spiral.
Described adjusting device is to fix a screw rod by blanking cavity upper end, and this screw rod is provided with spring and acts on the outer friction body end limit that is installed on the screw rod to be formed.
On screen cloth, be distributed with centrifugal guide face plate.
The husker sheller that this is novel, have on the rotation friction body that is adopted and be interrupted the column-shaped projection body that distributes, cooperate with the generating line projection that distributes on the outer friction body, when making it to corn threshing, by the intermittent bosses body of arranging on the rotation friction body, tangentially direction friction respectively mutual cross action in the corn barred body, thereby guaranteed the complete of corn bone, grain, reduced percentage of damage; In addition, this device is for the vertical structure body, the concentrated obstruction that causes in the threshing course when preventing that corn ear from falling, but and increased the adjusting device of outer friction body upper and lower displacement.When corn ear stops up, owing to be in operation process, corn ear acted on respectively on the outer friction body upwards produce displacement automatically, thereby changed the gap that rotates between friction body and the outer friction body, efficiently solve the rapid evacuation of block part, avoid the broken problem that is caused; In addition, it is little that this device has overall volume, and in light weight, project organization is simple, rationally, characteristics such as threshing efficiency, threshing performance and percentage of head rice height.
