Abstract

The utility model belongs to the field of agricultural machines, in particular to a thresher. The thresher comprises a base, a threshing cabin, a threshing drum, a threshing screen, a feeding hole, a slag-drip opening and a grain collecting device, wherein feeding hole is formed in one end of the cabin body of the threshing cabin; the slag-drip opening is formed in the other end of the cabin body of the threshing cabin; the threshing drum is arranged inside the cabin body of the threshing cabin; the threshing screen is arranged below the threshing drum; a cutting device is arranged on the feeding hole; a cutting component of the cutting device is a saw blade. By adopting the thresher, the defects of trouble in operation, long threshing time, low threshing efficiency, increase of the labor strength and incapability of automatically threshing ears in the threshing cabin during working of the thresher in the prior art are overcome. In the improved thresher, the cutting device is arranged on the feeding hole to control the length of threshed ears entering the threshing cabin, and the threshing cabin is used for automatically threshing cut ears, thereby greatly shortening the handholding time of threshed crops, increasing the working efficiency, and lowering the labor intensity.

Description

A kind of thresher
Technical field
The utility model belongs to agricultural mechanical field, particularly a kind of thresher.
Background technology
Due to the reason of physical features; in China's hilly and mountainous land area; large-scale combine is difficult to operation, just need to carry out threshing by hand harvest or with seed crops such as the paddy rice of small-sized machine harvesting, wheat, Chinese sorghum, broad beans, at this moment just need to generally utilize thresher.Thresher refers to can be by the crop kernels machine separation with stem stalk, existing thresher mainly comprises charging aperture, threshing cylinder, fan blower and slag-drip opening, during operation, a lot crops for the treatment of threshing of operator ', and its fringe portion is placed on to repetitious stirring on the threshing cylinder of rotation, under the effect of impact of the threshing cylinder spike-tooth of High Rotation Speed, carry out threshing; After threshing completes, operator throws away the straw of holding in hand again.After operation, the percent of loss of crops is high, threshing performance is low, percentage of impurity is high, wastes time and energy like this.
But while gathering in because of Grain Growth Situation, kind and people that custom is different causes results in different areas, the harvesting length of the whole strain of crops is not identical; the use region of thresher is restricted; and operate waywardly, threshing length consuming time, threshing efficiency is low, labour intensity is large, the low percent of loss of threshing performance is high.
Utility model content
Technical problem to be solved in the utility model is in when work for thresher in prior art, need allow and repeatedly repeatedly be stirred on threshing cylinder by the fringe portion of threshing object, the threshing length being stretched into by threshing object also needs to rely on artificial experience and wayward, and troublesome poeration, threshing length consuming time, threshing efficiency is low, labour intensity is large, threshing bin can not carry out automatic threshing and thresher uses the defects such as region is restricted to fringe portion; Thresher after a kind of improvement is provided; at charging aperture place, set cutter sweep and control the length that is entered threshing bin by threshing object fringe portion; threshing bin carries out automatic threshing to cut fringe portion; significantly improved threshing efficiency; greatly reduced the time of holding threshing object; improve operating efficiency and alleviated labour intensity, and can meet the threshing operations needs of the various seed crops of zones of different, different cultivars and different length.
In order to solve the problems of the technologies described above; the utility model provides following technical scheme: a kind of thresher; comprise support, threshing bin, threshing cylinder, threshing screen cloth, charging aperture, slag-drip opening; charging aperture is located at one end of threshing bin warehouse; slag-drip opening is located at the other end of threshing bin warehouse, and threshing cylinder is located at threshing bin warehouse inside, and threshing screen cloth is located at the below of threshing cylinder; charging aperture place is provided with cutter sweep, and the cutting part of described cutter sweep is saw blade.
Operation principle of the present utility model is as follows: operator holds the paddy rice of a whole strain length (for the ease of understanding, this sentences the paddy rice of choosing in crops), its fringe portion is sent into charging aperture and allows fringe contact hold together charging aperture corresponding opposite baffle, the whereabouts of taking advantage of a situation, is fed the rotating saw blade that mouth is provided with and cuts off fringe portion and the stalk portion of paddy rice; Fringe portion is rotated cylinder and is involved in threshing bin warehouse, fringe portion is subject to stirring shock and seed is taken off, seed enters collection grain device again after thrashing screen mesh screen choosing, and careless slag is discharged from slag-drip opening, at remaining most of stalk on hand, throws away in time and repeat to feed operation.
The beneficial effects of the utility model are as follows: 1, on charging aperture, design cutter sweep, effectively controlled the length that is entered threshing bin by threshing object.The cutting part of described cutter sweep is saw blade, and the distance of saw blade and charging aperture corresponding opposite baffle is cut by threshing object fringe portion the length that enters threshing bin.
2, crops threshing has been adopted to automatic threshing course, only need be at the processing initial stage, crops are taken advantage of a situation and ride over charging aperture, after crops are cut, throw away the remaining stalk of crops portion, avoided needing people with the hand-tight agricultural crop straw of holding, allowed its fringe portion on threshing cylinder, repeatedly repeatedly stir the defect of carrying out threshing, saved the threshing time, reduce and can (oil) consume and alleviated labour intensity.
3, adopt automatic threshing and at charging aperture place, cutter sweep be set, effectively controlling the processing sections length of crops etc., all making threshing bin stable work in work, the grain loss rate of crops reduces, threshing performance improves, percentage of impurity reduces, and has improved operating efficiency.
Further, described support is ship shape or frame shape; When the seed in fringe portion is fallen on the support of below after thrashing screen mesh screen choosing thereupon, ship shape support can make seed directly fall in support shipshape vessel; In the pocket that frame shape support can make seed enter to arrange on support or other collection grain device.
On described charging aperture, can also overlap and have splashproof to protect paulin in addition; When the saw blade of charging aperture cuts, fringe portion seed may splash, and splashproof protects paulin and makes it finally falling back in charging aperture, has improved the rate of recovery.
