Abstract
The invention belongs to agricultural mechanical fields, propose a kind of maize sheller with speed-regulating function, including rack, drum threshing part and speed governing part.Rack section is made of upper and lower rack.Drum threshing part is mainly made of cylinder body, grid sieve plate, threshing spindle, collectively forms thrashing cylinder with upper spider.Speed governing part includes motor, retarder, variable speed wheel, the band determining belt wheel and being wound on belt wheel, tensioning apparatus.Variable speed wheel is taken turns by dynamic half and fixed half wheel forms.When the present apparatus works, according to the moisture of different corns, belt speed can be adjusted, to meet the needs of different.Corn is put into feeding inlet, corn pushes forward under the promotion of the screw type tooth of self-control roller.Under the action of roller appearance threshing tooth, corn kernel and cob separates under the action of squeezing and rubbing power with the hands, and grain export is fallen niblet from below, and corn ear comes out from the rod outlet of tail portion.The apparatus structure is compact, has speed regulation device, is a kind of novel corn threshing mechanism.
Description
Technical field
The present invention relates to agricultural mechanical field, specially a kind of variable speed using band realizes that the corn of speed changing function is de-
Grain machine.
Background technique
With the development of the society, mechanical each corner for being flooded with life.Agricultural is the most basic economy in China,
It is also the most basic guarantee of national development.Popularizing for mechanization, can improve the efficiency of agricultural production, can also mitigate the work of peasant
It bears.It has been shown that, 2018/19 annual Chinese jade are reported according to the Global Agriculture yield in October of United States Department of Agriculture (USDA) publication
Rice yield is estimated to reach record-breaking 2.25 hundred million tons, increases by 4% than last year, increases by 3% than five yearly mean levels.Science in Future in China is beautiful
The yield of rice still can continue to increase, this just promotes corn planting to need to realize mechanization mass production.According to incompletely statistics, northern
Most area realizes do mechanization operation from harvest is seeded into storehouse.Here only to the mechanization of threshing after harvest corn into
Row, which discusses, to be improved.
Maize sheller, through air-drying after a period of time, is finally separated corn ear and niblet after corn is peeled
A kind of machinery.For this thresher machine, the principle of threshing is different, and threshing efficiency is also different.Its principle mainly has two
Kind: impact type corn threshing and crowded stranding formula corn threshing.
There are many insufficient for existing maize sheller: firstly, under corn threshing performance, remaining in above corn ear after threshing
Niblet also need manually to be rubbed with the hands；Secondly, corn percentage of damage is high, corn is easy to cause to go mouldy；Finally, existing
Thresing machine is easy to happen machine stuck phenomenon.So being badly in need of a new thresing machine now to make up existing defect.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of novel maize sheller.
Technical scheme is as follows:

Different dynamic half takes turns and fixed half takes turns, and two and half wheels nest together；Variable speed wheel is connected to the end of threshing spindle by spline, becomes
Double nut is arranged in belt wheel outboard end, and axial restraint is carried out to it and adjusts variable speed wheel with this double nut；When nut is tightened, variable speed
Wheel engaging portion diameter becomes larger, and threshing axle revolving speed reduces, conversely, diameter becomes smaller when nut turns outward, threshing axle revolving speed is promoted.
The tensioning apparatus, comprising: tensioning wheel, clump weight and supporting beam；Supporting beam is placed in reducer output shaft, Gu
It is scheduled on belt wheel both ends；Tensioning wheel is installed in supporting beam one end, and the other end installs clump weight, and the one end for installing clump weight is provided with ditch
Slot is arranged aperture on clump weight, presses closer groove horizontal plane using Bolt through holes, clump weight position is adjusted；Tensioning wheel
Belt is compressed, is determined outside belt wheel by the way of side compression using close；According to different revolving speeds, the position of clump weight is adjusted, makes to open
Bearing up pulley is pressed on belt always.
The rack section includes upper spider and lower bearing bracket；Upper spider and lower bearing bracket are using together with bolt tightening；Upper machine
Frame is semi-cylindrical casing, and both ends are separated with the partition covered on axis with the external world, and upside is equipped with feeding inlet, and side sets up corn ear
Discharge port；Lower bearing bracket is welded by angle steel, divides into the support plate for carrying motor and shaft coupling, and niblet discharge port is set up
Below rack, it is connected by welding with lower bearing bracket.
The application method of the maize sheller is:
Step 1 opens motor, and corn is added in feeding port, and corn is by thrashing cylinder, and discharge port comes out niblet from below,
Corn ear comes out from side discharge port.
Step 2, if it find that come out niblet be crushed it is more, selection reduce revolving speed, close motor, movable belt pulley end
Adjusting nut tighten, open motor continue to operate.If it find that threshing is not clean above ear of maize, selection improves revolving speed, stops
Nut is turned outward, reaches speed-raising purpose by machine.
The invention has the advantages and beneficial effects that:
1. the present invention changes existing maize sheller, there is stepless shift function, run smoothly, it can be more preferable
Ground meets and adapts to the niblet requirement of different regions.
2. threshing part is transformed in the present invention, using two kinds of different teeth, the abundant threshing of corn can be made, and transport

Embodiment
The present embodiment provides corn threshing devices as shown in Figure 1, comprising: cylinder body 1, two bearing block 2, threshing master
Axis 3, grid sieve plate 5, motor 9, retarder 10, variable speed wheel 11, determines belt wheel 12, is wound on belt wheel a pair of of tapered roller bearing 4
Band 13, tensioning apparatus 14, upper spider 21, lower bearing bracket 22.
When maize sheller is worked, motor 9 is opened, and power is transferred to threshing by retarder 10 and V belt translation
Main shaft 3, at this point, corn enters from feeding inlet 25, under the roller effect under threshing spindle drive, corn carries out threshing.If
It was found that come out niblet be crushed it is more, when needing to reduce speed, close motor 9, the adjustment double nut of 11 end of variable speed wheel
17 tighten, and open motor 9 and work on, at this point, the change of band 13 being wound on belt wheel is tightened since V belt translation center is away from constant, this
When tensioning apparatus 14 on clump weight 19 inwardly slide, so that tensioning wheel is pressed the band 13 being wound on belt wheel always, maintain V belt translation after
It is continuous.If it find that threshing is not clean above ear of maize, selection improves revolving speed, stops machine, double nut 17 is turned outward, same to specimen page
Tight device plays a role, and continues to V belt translation, reaches speed-raising purpose.Operation in this way, niblet is finally and corn
Stick is detached from, and is come out respectively from respective discharge port, and threshing is completed.
