Description

Corn dicyclo thrasher

The utility model relates to a kind of corn thresher, particularly relates to a kind of small-sized hand-operated corn dicyclo thrasher.

Corn after the maturation needs threshing, and in small-scale corn planting district, modal method is that corn ear is pulled threshing with hand, this method, and efficient is low, and damages hand again.Chinese patent CN89212777.5 provides a kind of corn thresher, its profile is a conical shell, welded finger on the Method of Variable Pitch Screw of the simplified circumferencial direction in simplified upper edge, tubular axis is pointed on the top of tooth, and tooth top changes with the cylindrical shell gradient apart from simplified distance.With artificial power.During use corn ear is filled in the pipe, with the manual mode turne tube, the internal tooth in the pipe rotates thereupon, iblet is taken off, and this thrasher processed complex, cost is higher, and fixing corn ear during operation uses inconvenient.And in extensive corn planting district, what then use is large-scale thresher, and the cost height is unsuitable for the rural area peasant farmer and uses.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and cost is low, is suitable for the corn dicyclo thrasher that the rural area vast farmers uses.

The utility model corn dicyclo thrasher is to realize like this, it comprises big ring and little ring in two adjacent connections and the plane, be evenly distributed on big ring and the little ring internal ring wall, and with the internal tooth of large and small ring structure in aggregates, be arranged on the handle of big ring or little ring one end.Wherein, will encircle greatly with little ring and be arranged to overall structure, and process more conveniently, its internal diameter is advisable with the diameter that adapts to corn ear, and large and small ring needs applicable to the threshing of the large and small corn ear of difference.Generally at least 3 of the internal tooths of little ring, the internal tooth of ring is generally at least 5 greatly, and casts an overall structure with large and small ring, and is easy to process.Handle can be arranged on big ring one end, also can be arranged on little ring one end, but it is more laborsaving to be arranged on big ring one end, for easy to process, also casts an integral body with big ring.

The operation principle of the utility model corn dicyclo thrasher is, during use, take corn ear on the other hand, another holds the handle of corn thresher, corn ear is put in big ring of thrasher or the little ring, when making relative crankmotion, also move horizontally, internal tooth in the ring is taken off the iblet on the corn ear by its friction.

The advantage of the utility model corn dicyclo thrasher is simple in structure, and cost is low, and is easy to use, is particularly suitable for the corn threshing needs of vast countryside and peasantry.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
