Abstract

The utility model relates to a hand-operated and used corn thresher composed of threshing rings and a handle, which is characterized in that the integrated big, middle and small threshing rings forming a plate type structure of a shape like the Chinese character 'pin '; the ring bodies of the big threshing ring and the middle threshing ring are connected with the handle; the inner circumferences of the rings are uniformly distributed with threshing teeth; the matching of the small threshing ring and the middle threshing ring or the middle threshing ring and the big threshing ring enables corn cobs with different sizes to complete threshing by means of a thresher. The utility model has the advantages of simple structure, small size and easy and convenient operation; compared with human power manual labor threshing, the speed is improved by 10-15 times; the utility model is time-saving and labor-saving.

Description

Corn thresher

The utility model relates to a kind of thrasher, the corn thresher that especially a kind of manpower manual operations is used.

Existing corn threshing device has two types usually, and a kind of is electronic or power-actuated husker sheller, this thresher, threshing efficiency is all higher, and be fit to collective's corn threshing in enormous quantities and use, but because its price comparison costliness, common peasant household is difficult to buy, be difficult for extensively promoting the use of, in addition, this husker sheller, percentage of damage is also higher, and its threshing corn should not be continued to employ as seed; Another is exactly a wrench formula corn thresher; this thrasher; form by threshing ring and handle, be fit to peasant household's manual operations and use, but this thrasher; because not of uniform size the causing of height of corn; have greatly, also have for a short time, so the different corn of size specification just can't lean on and same corn thresher finished corn threshing; must be handy many thrasher be used alternatingly, thereby causes greatly reducing operating efficiency.

The purpose of this utility model is that a kind of improved corn thresher will be provided, and it is not only simple in structure, and is easy to manufacture, and the corn ear of various different size sizes can be finished threshing to thrasher with same.

The utility model is achieved in that this corn thresher; form by threshing ring and handle; in order to be fit to corn threshing not of uniform size; the threshing ring of big threshing ring, middle threshing ring and three kinds of different sizes of little threshing ring is merged into a corn thresher; three threshing rings are Chinese character pin-shaped plank frame; the ring body of big threshing ring and middle threshing ring is connected with handle, is evenly equipped with the threshing tooth on the inner rim of each ring.When corn threshing; because corn ear one end is little than taper, in less threshing ring after the threshing, again that remainder is a thicker end moves on to threshing in the bigger threshing ring with this end; being used of large, medium and small three threshing rings in the thrasher can be finished the threshing of various corns not of uniform size.

The utlity model has following advantage:

1, simple in structure, easy to manufacture, cost is low, and volume is little, and is easy and convenient to handle.

2, corn threshing efficient height, than the fast 10-15 of the manual threshing of manpower doubly.

3, can broken corn.

4, once the threshing that can finish thrasher various corns not of uniform size.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation according to the corn thresher that the utility model proposes.

Fig. 2 is the end view of Fig. 1.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Referring to Fig. 1; Fig. 2; this corn thresher; cast by the metal material one; comprise threshing ring and handle; the big threshing ring (5) of disjunctor; middle threshing ring (2) and little threshing ring (3) are Chinese character pin-shaped plank frame; the ring body of big threshing ring (5) and middle threshing ring (2) is connected with handle (1) disjunctor; big threshing ring (5); be evenly equipped with 6 respectively on the inner rim of middle threshing ring (2) and little threshing ring (3); 5; 4 threshing teeth (4); the ring internal diameter of big threshing ring (5) and tooth footpath are respectively 6 centimetres and 3.6 centimetres; the ring internal diameter of middle threshing ring (2) and tooth footpath are respectively 4.8 centimetres and 2.7 centimetres; the ring internal diameter of little threshing ring (3) and tooth footpath are respectively 4.3 centimetres and 2 centimetres; because corn ear all is that the thin end of an end is thick; the progressive gradually thick and needs of being convenient to threshing during for corn rod threshing; threshing tooth (4) is made chicken mouth formula triangular tooth; chicken mouth formula triangular threshing tooth tilts in corn import one side direction in each threshing ring and the ring, and it is wide outside and narrow inside that collar extension is.

During use; can be according to corn size thickness; select little threshing ring (3) and middle threshing ring (2); or middle threshing ring (2) and big threshing ring (5), between these two groups, be used alternatingly respectively, catch corn ear with left hand; catch the handle (1) of thrasher with the right hand; left hand advances corn, and the right hand rotates back and forth thrasher, and the iblet on the corn ear just constantly comes off.

Claims

1. corn thresher; form by threshing ring and handle; the big threshing ring (5), middle threshing ring (2) and the little threshing ring (3) that it is characterized in that disjunctor are Chinese character pin-shaped plank frame; the ring body of big threshing ring (5) and middle threshing ring (2) is connected with handle (1), is evenly equipped with threshing tooth (4) on the inner rim of each ring.

2. corn thresher according to claim 1 is characterized in that threshing tooth (4) is a chicken mouth formula triangular tooth, and the threshing tooth tilts in corn import one side direction in each threshing ring and the ring, and it is wide outside and narrow inside that collar extension is.
