Description

Portable husker sheller

Technical field: the utility model discloses a kind of corn threshing device, a kind of specifically engine prolong knot direct and tractor moves, and is to drag the matching used portable husker sheller of a machine more than 15 horsepowers (being 11KW).

Background technology: at present; development along with China's agricultural cience and farming techniques; the output of grain is greatly improved; particularly in the north of China; maize yield has reached quite high level; the threshing of corn is also by original manual threshing; realized semi-mechanization and mechanization, on the agricultural machinery market of China, the equipment that is used for corn threshing at present is a lot; as the patent No. be 02275301.X in first to file; they all exist many shortcoming and defect, are in particular in: 1) traditional its cleaning plant of husker sheller adopts the blower fan transmission, and blower fan motion seed in operation pushes mutually; seed and blade push friction mutually, and seed damage is many.2) connection between its reciprocating sieve part of traditional husker sheller and the frame is to adopt the bearing element ways of connecting to realize swinging function, its shortcoming be when freezing, on become rusty or when entering foreign material, swing function and can't realize.3) traditional reciprocating sieve is to carry out secondary by the two layer screen sheet to clean, impurity and broken seed directly leak on the ground, if want meticulous impurity is separated the needs artificial screening with broken seed, waste time and energy, some peasant household is for fear of trouble, simply it is thrown away, caused unnecessary waste.4) traditional its corncob outlet of husker sheller and the corncob vibratory sieve end that all is arranged on the axial direction of detachment machine drum spindle; at axial notch board place; be called axial-flow type corn detachment machine; the corncob reciprocating sieve is done reciprocally swinging with the speed of main shaft; because axial thrust is more than 5 times of radial thrust; corn ear is in notch board and under the effect of cylinder like this; the gentle wiping; extruding; march on towards the corncob outlet then fast, it is in small, broken bits that corncob becomes, and is mingled with some seeds simultaneously; get rid of externally, caused the fragmentation of corncob and the waste of grain.

Summary of the invention: the purpose of this utility model be to provide a kind of simple and reasonable, yield rate is high, do not have the portable husker sheller of waste, this husker sheller adopts and the synchronous motion mode of tractor, being transported to of having no to collide by belt transmission in the packaging bag the finished product of grain calmness; Reciprocating sieve part that is adopted and the connection between the frame are to flexibly connect; Reciprocating sieve partly is on the basis that two-stage is cleaned, and increases the part of cleaning of one-level impurity and broken seed; Change corncob outlet and corncob vibratory sieve into radially setting by axial setting, it is consistent synchronously with speed that three layers of sieve nest of corncob vibratory sieve and thresher are become the rigid motion direction, reduces the fragmentation of corncob and the waste of grain, reduced the noise of equipment.

The purpose of this utility model is to realize like this; this husker sheller comprises reciprocating sieve; frame; notch board; cylinder; eccentric wheel, clutch wheel, blower fan; the excellent conveyer of fruit; engine shaft, finished product of grain are carried and are irritated bagging apparatus, corncob outlet; its reciprocating sieve is made of four layers of screen cloth; finished product of grain carry to irritate bagging apparatus adopt conveyer belt type structure, be arranged on the 3rd layer of screen cloth finished product of grain outlet place of reciprocating sieve, adopt a plurality of flexible link plates to be connected between reciprocating sieve and frame, the corncob outlet is arranged on the radially notch board place of drum spindle end.

Described reciprocating sieve top layer is the corncob cleaning vibration sieve, one end of sieve nest has opening, the end of the 3rd layer of screen cloth in reciprocating sieve side has the finished product of grain outlet, the head end of the 4th layer of screen cloth has small impurities and broken seed outlet, and the mesh size size of four layers of screen cloth of reciprocating sieve is top layer 12 * 12mm, two layers of 12 * 12mm, three layers of 6 * 6mm, the 4th layer of 3 * 3mm.

Described corncob outlet place is provided with valve, balance weight iron, and four layers of screen cloth on the described reciprocating sieve are connected as a single entity, are synchronized with the movement by support.

Described finished product of grain is carried and is irritated packed last procedure that is changed to husker sheller; be used for finishing finished product of grain and carry and irritate bag; it be by drivenly roll, bearing block, pulley, conveyer belt, initiatively roll, support body, location lacing wire constitute, moving the rolling of principal and subordinate all has the tensioning guiding mechanism.

Described fruit rod conveyer and finished product of grain carry moving the rolling of the principal and subordinate who irritates on the bagging apparatus to adopt two ends not to be the rolling cage type structure of cone shape with the inside of plug.

Described driven roll and initiatively roll by connecting axle, axle sleeve, have the conical surface roll the both sides cylindrical, tilt uniform be arranged on axle sleeve and roll many diagonal bars between the cylindrical of both sides, the parallel uniform many horizontal bars that roll between the cylindrical of both sides that are arranged on constitute.

The utility model is owing to adopted above-mentioned structure to have the following advantages:

1, the flexible belt motion that is synchronized with the movement of employing and tractor has no to collide passes through finished product of grain and carries and irritate bagging apparatus and finished product of grain is carried irritated bag; having overcome traditional blower fan and screw feeder carries; seed pushes mutually in the operation; seed and blade push friction mutually; the shortcoming that seed damage is many makes the quality of finished product of grain be greatly improved.

2, on the basis of the two-layer screen cloth of traditional husker sheller reciprocating sieve; increase one deck corncob in the above and clean screen cloth; increased one deck fine screen mesh below; realized that level Four cleans; cleannes and the commercial grade of threshing performance, grain have significantly been improved; the seed that corncob in the past is entrained with is cleaned simultaneously; direct leakage impurity and broken seed on the ground cleaned by fourth stage fine screen mesh; meticulous impurity and broken seed are separated; time saving and energy saving, avoided unnecessary waste.

3, flexibly connecting between reciprocating sieve part and the frame, overcome traditional husker sheller freezing, on rust or swing function can't realize when entering foreign material shortcoming, the work swing of reciprocating sieve part is freedom more.

4, excellent conveyer of fruit and finished product of grain are carried moving the rolling owing to adopted two ends not to be the rolling cage type structure of cone shape with the inside of plug of principal and subordinate on the filling bagging apparatus; the principal and subordinate is moving when having overcome husker sheller work rolls owing to enter foreign material and stop up and make the drawback that machine can't operate as normal; it is more normal to have a machine in operation, and fault rate is low.
