Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, this corn high effective sheller unit includes threshing box 1, grain threshing roller 3, collection device and power device;
Discharge port 13 is arranged in 3 lower end of the grain threshing roller installation chassis 11, left upper end setting feed inlet 14, right end,
The power device includes rotary electric machine 21, is fixedly connected with 21 output end of rotary electric machine driving wheel 22 and is located at master
The driven wheel 24 of 22 side of driving wheel, the driving wheel 22 and driven wheel 24 are connected by the transmission belt 23 of winding on the outside;
Described 3 axis of grain threshing roller or so is placed, and is rotatably installed in threshing box 1, and the fixed of 3 left end of grain threshing roller connects
It connects on driven wheel 24, the first spiral 32 and multiple first spike-tooths 31, multiple first nails is set on the left half of the grain threshing roller 3
Tooth 31 is arranged in a staggered manner with the first spiral 32, and the second spiral 34 and multiple second spike-tooths 33 are arranged on the middle part of the grain threshing roller 3,
Multiple second spike-tooths 33 are arranged in a staggered manner with the second spiral 34, and third spiral 36 and multiple is arranged on the right half of the grain threshing roller 3
Third spike-tooth 35, multiple third spike-tooths 35 are arranged in a staggered manner with third spiral 36,
Through-hole is respectively set in the lower end of 1 left half of threshing box, middle part and right half, and the collection device is three
Group is located at the left half of threshing box 1, the lower end of middle part and right half, that is, be located at 3 left half of grain threshing roller, middle part and
The lower section of right half, the collection device include collecting box 41, support frame 42 and threshing board 43;The setting of support frame 42 is de-
The lower end of grain case 1, threshing hole is arranged on the threshing board 43, and the threshing board 43 is connected by compressed spring 44 and support frame 42
It connects, the collecting box 41 is located at 42 lower section of support frame;
The threshing board 43 on the left side, middle part and the right is separately positioned in three through-holes of threshing box 1.
Further, screw pitch of the screw pitch of the third spiral 36 less than the second spiral 34, the spiral shell of second spiral 34
Away from the screw pitch less than the first spiral 32;Part, again middling speed are fast moved into grain threshing roller 3 in 3 left half of grain threshing roller by corn
It is moved to 3 right half of grain threshing roller, is then slowly moved to discharge port 13, facilitates and realizes that the classification threshing to corn is handled.
Further, the quantity of second spike-tooth 33 is greater than the quantity of the first spike-tooth 31, less than the number of third spike-tooth 35
Amount;Therefore preliminary to corn, secondary, threshing three times is realized by the first spike-tooth 31, the second spike-tooth 33 and third spike-tooth 35, and
With increasing for spike-tooth quantity, so that Threshing becomes apparent from, complete threshing is ensured.
Further, between the left side through-hole and middle through-hole of the threshing box 1 be arranged first partition 51, middle through-hole and
Second partition 52 is arranged in the right through-hole, and third partition, the first partition is arranged in 1 right end of threshing box at discharge port 13
51 upper-lower height is greater than the height of second partition 52;Therefore pass through first partition 51 and second partition 52 for different degrees of threshing
Corn afterwards is spaced, so that the niblet after threshing is fallen from threshing board 43 completely, and avoids jade using third partition
The grain of rice is moved to 1 right end of threshing box and is discharged from discharge port 13.
Further, the threshing hole on left side threshing board 43 is greater than the threshing hole on middle part threshing board 43, middle part threshing board
Threshing hole on 43 is greater than the threshing hole on the right threshing board 43;It is realized by the setting of different threshing holes size to different degrees of
The filtering of the niblet of threshing.
Further, the threshing bore dia on the right threshing board 43 is 6mm~20mm.
Further, closing door 12 is rotatablely installed at the discharge port 13.
Further, the chassis 11 uses upper and lower stretching structure;Chassis 11 has Telescopic, not only realizes whole high
The adjustment of degree, and facilitate being obliquely installed for threshing box 1, facilitate discharging.
For a kind of this corn high effective sheller unit in use, starting rotary electric machine 21 first, rotary electric machine 21 drives driving wheel
22 and driven wheel 24 rotate, realize the rotation of grain threshing roller 3, then corn is put into threshing box 1 from feed inlet 14, grain threshing roller 3 is left
Corn is carried out preliminary threshing processing by the first partial spike-tooth 31, and corn is moved to the middle part of grain threshing roller 3 by the first spiral 32,
The niblet of preliminary threshing is fallen into the collecting box 41 on the left side by the threshing board 43 on the left side, the second nail of part in grain threshing roller 3
Corn is carried out secondary threshing processing by tooth 33, and corn is moved to the right half of grain threshing roller 3 by the second spiral 34, again the jade of threshing
The grain of rice is fallen by the threshing board 43 at middle part in the collecting box 41 at middle part, the third spike-tooth 35 of 3 right half of grain threshing roller by corn into
Threshing is handled row three times, by the complete niblet of threshing out of, the threshing board 43 on the right falls into the right collecting box 41, and is led to
It crosses third spiral 36 corn ear stalk is transferred at discharge port 13, therefore not only realizes the efficient threshing of corn, but also threshing is more
Add it is complete, the case where avoiding threshing there are still niblets on corn ear not in time;It is arranged additionally, due to 43 lower end of threshing board and compresses
Spring 44 is mounted on 42 top of support frame by compressed spring 44, therefore passes through each spike-tooth on grain threshing roller 3 and 43 bullet of threshing board
Property contact, avoid threshing rigid contact from causing the damage to niblet.
