Left and right sides framework forms sheet 321L, 321R and is respectively along the plate-shaped member of the linearity of fore-and-aft direction extension, and framework forms between the mutual left and right end portions of sheet 321F, 321B before and after being set up in.Like this, framework 321 forms sheet 321F, 321B and left and right sides framework by the front and back framework and forms sheet 321L, 321R and constitute the frame shape.
Possess a plurality of sieve nests at sieve nest 322 and form sheet 322A.Sieve nest forms sheet 322A and forms along the bar-like member of the linearity of fore-and-aft direction extension, and in the present embodiment, forming special in bar-like member is the cylinder-like part of curved surface with the outer peripheral face.A plurality of sieve nests form sheet 322A and dispose abreast with left and right sides framework formation sheet 321L, 321R respectively, form between sheet 321F, 321B along its bending direction framework before and after predetermined distance is set up in.
At this, sieve nest forms sheet 322A and is set to as shown in Figure 9, and its internal diameter is certain in the fore-and-aft direction scope, and the end 322Aa before and after external diameter is limited to is a path, and near the mode that is considered as convex with section the end of front and back constitutes.On the other hand, the framework of front and back forms sheet 321F, 321B and possesses every predetermined distance along bending direction and have end 322Aa almost a plurality of through hole 321Fa, the 321Ba of same diameter that forms the front and back of sheet 322A with sieve nest.
And the end 322Aa that sieve nest forms the front and back of sheet 322A embeds respectively with the front and back framework and forms sheet 321F, through hole 321Fa, 321Ba that 321B is corresponding.Thus, framework formed the scope between sheet 321F, the 321B before and after sieve nest formation sheet 322A was arranged at, and formed sheet 321F, 321B by the front and back framework and prevented deviating from, and be supported freely around the axis rotation of this sieve nest formation sheet 322A.Below, describe with end 322Aa and the outer peripheral face of outer peripheral faces processing cylinder 31 opposed parts that removes sieve nest formation sheet 322A as sieve nest formation sheet 322A.
Form in the supporting structure of sheet 322A at this sieve nest, sieve nest forms sheet 322A as shown in Figure 9, comparing suitably increase with the external diameter of end, front and back 322Aa with the external diameter of these processing cylinder 31 opposed parts sets, as shown in Figure 5, so that the equidistant mode to the outer peripheral face of handling cylinder 31 disposes to the processing cylinder side end face of the distance of the outer peripheral face of handling cylinder 31 and the past after-frame bodily form 321F in blocks, 321B from handling the cylinder outer peripheral face.That is, sieve nest forms sheet 322A and handles cylinder side outer peripheral face with it and be positioned at and form the mode that the processing cylinder side end face of sheet 321F, 321B is almost with one side with the front and back framework and dispose.
In addition, sieve nest forms sheet 322A and compares with the external diameter of the end 322Aa of front and back suitably to increase with the external diameter of these processings cylinder 31 opposed parts and set, to dispose from handling cylinder side outer peripheral face to the distance of the outer peripheral face of handling cylinder 31 forms sheet 321F, 321B than the framework from front and back processing cylinder side end face to the mode of the distance weak point of the outer peripheral face of handling cylinder 31.That is, sieve nest formation sheet 322A disposes than the mode that front and back framework forms the more approaching processing cylinder 31 in processing cylinder side end face of sheet 321F, 321B to handle cylinder side outer peripheral face.
In other words, sieve nest forms sheet 322A and compares suitably increase setting with the external diameter of the end 322Aa of front and back with the external diameter of these threshing tube 31 opposed parts, as shown in Figure 5, with handle cylinder side outer peripheral face from processing cylinder side end face that the framework of front and back forms sheet 321F, 321B hardly to handling the side-prominent mode of cylinder 31, or more dispose to handling cylinder 31 side-prominent modes with the processing cylinder side end face that the framework than front and back forms sheet 321F, 321B.
In addition, sieve nest forms sheet 322A supporting structure shown in Figure 10 (a), also can be following formation: external diameter and the framework in front and back of setting sieve nest formation sheet 322A form sheet 321F roughly the samely, the through hole 321Fb that 321B possesses, the external diameter of 321Bb, so that forming the end 322Ac of the front and back of sheet 322A, sieve nest runs through through hole 321Fb, the state of 321Bb, by making from the framework formation sheet 321F of the front and back of each end 322Ac, the external diameter of the part that 321B gives prominence to laterally is than through hole 321Fb, the external diameter of 321Bb is big, prevent that sieve nest from forming sheet 322A after-frame bodily form 321F in blocks in the past, 321B deviates from, and supports freely around the axis rotation of this sieve nest formation sheet 322A.
Perhaps, sieve nest forms the supporting structure of sheet 322A shown in Figure 10 (b), set firmly the supporting mass 325 of a plurality of ring-types by the framework inboard that forms sheet 321F, 321B in the front and back framework, the end 322Aa that makes each sieve nest form sheet 322A embeds in this supporting mass 325, also can form sheet 321F, 321B rotation with respect to the front and back framework thus and support sieve nest formation sheet 322A freely.
Under the situation of this supporting structure, form on sheet 321F, the 321B to have the little diameter of internal diameter that forms sheet 322A than sieve nest in the front and back framework and to form a plurality of through hole 321Fb, 321Bb, and be that concentric mode is configured with opening with each supporting mass 325.And, more by the framework inboard, near the end 322Aa of sieve nest formation sheet 322A, be formed with through hole 322Ad than supporting mass 325.
Like this, form the state of the internal communication of sheet 322A, be communicated with the inside and outside of supporting mass 325, and be communicated with sieve nest by through hole 322Ad and form the inside and outside of sheet 322A by through hole 321Fa, 321Ba with the inside of supporting mass 325 and sieve nest.
Thus, in the tip-clearance of supporting mass 325 and framework formation sheet, piled up under the situation of dust, by utilize air gun etc. in the past through hole 321Fa, the 321Ba of after-frame bodily form 321F in blocks, 321B towards the delivered inside air of supporting mass 325, can remove this dust simply, realize preventing that the rotation that is formed sheet 322A by the sieve nest that dust causes from stopping.
In addition, form in the supporting structure of sheet 322A at above-mentioned sieve nest, a plurality of sieve nests form sheet 322A and see in the front of handling cylinder 31, as shown in Figure 5, form sheet 322A and form sheet 322A forms sheet 322A at the adjacent sieve nest of bending direction of front and back framework formation sheet 321F, 321B interval with certain sieve nest with respect to this sieve nest, handle tooth 313 at the interval of the leading section of the adjacent processing tooth 313 of fore-and-aft direction with the leading section of certain processing tooth 313 of handling cylinder 31 with respect to this, circumferentially arrange for the mode of same degree at the processing cylinder.
Therefore, certain sieve nest forms sheet 322A and together is disposed at from the pivot of handling cylinder 31 when handling the first straight line L1 that the cylinder radial outside extends and go up with handling tooth 313, forms sheet 322A with respect to certain sieve nest and forms sheet 322A at the adjacent sieve nest of bending direction that the framework of front and back forms sheet 321F, 321B and also be disposed at the adjacent processing tooth 313 of fore-and-aft direction and handling the cylinder predetermined angular that circumferentially staggers from the pivot of handling cylinder 31 with respect to the first straight line L1 and form to handling on the second straight line L2 that the cylinder radial outside extends with handle tooth 313 with respect to certain.
Promptly, certain sieve nest form sheet 322A with handle cylinder 31 certain when handling the opposed mode of tooth 313 leading sections and disposing, with respect to certain sieve nest form the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B form sheet 322A also with handle tooth 313 with respect to certain and dispose and form in the opposed mode of leading section of the adjacent processing tooth 313 of fore-and-aft direction.In other words, mutually adjacent sieve nest form sheet 322A with the adjacent leading section of respectively handling tooth 313 of the fore-and-aft direction of handling cylinder 31 simultaneously opposed mode dispose and form.
At this moment, see in the front of handling cylinder 31 handle cylinder 31 respectively handle tooth 313 and with respect to this processing tooth 313 at the circumferential interval of the processing cylinder of the adjacent processing tooth 313 of fore-and-aft direction because of set as previously mentioned roughly the samely, therefore, each sieve nest forms sheet 322A and forms sheet 322A with respect to this sieve nest and sets at the circumferential interval of processing cylinder of the adjacent sieve nest formation sheet 322A of the bending direction of front and back framework formation sheet 321F, 321B also roughly the samely.Therefore, a plurality of sieve nests formation sheet 322A equally spaced arrange at the bending direction that the front and back framework forms sheet 321F, 321B.
In addition, in the present embodiment a plurality of sieve nests are formed sheet and form sheet interval each other with identical at the leading section interval each other of handling tooth with sieve nest, and handling tooth rim to arranging for equally spaced mode, but, change corresponding to the leading section interval each other of handling tooth, sieve nest forms sheet interval each other also can be big to form sheet interval each other at a part of sieve nest, forms little mode unequal interval ground, sheet interval each other at remaining sieve nest and arrange.
In addition, shown in Figure 11 (a), lining body 323F, the 323B of front and back also can be set respectively in the framework formation sheet 321F of the front and back of supporting sieve nest formation sheet 322A, the framework outside of 321B.Lining body 323F, 323B are made as identical structure respectively, have fixed part 323Fa, 323Ba and the 323Fb of lining portion, 323Bb, shown in Figure 11 (b), form and analyse and observe L word shape.
Fixed part 323Fa, 323Ba form with the front and back framework and form sheet 321F, the roughly the same shape of 321B.And fixed part 323Fa, 323Ba dispose in the mode that forms sheet 321F, 321B from the framework outside and front and back framework and overlap, and be relative with it, releasably fixes via connecting piece every predetermined distance at bending direction.
The 323Fb of lining portion, 323Bb has and the front and back framework forms sheet 321F, 321B the width of bending direction extend along fore-and-aft direction towards the framework inboard from the upper end of fixed part 323Fa, 323Ba with the width ground formation of degree.At this moment the sieve nest of framework formation sheet 321F, 321B formed the degree of the supporting part of sheet 322A before and after the front and back width of the 323Fb of lining portion, 323Bb was set at and can covers.
Like this, the threshing portion 30 of combine 1, female part 32 also can be following formation: form in the front and back of framework 321 framework front and back lining body 323F, the 323B that forms the swivel bearing part of sheet 322A from each sieve nest of handling cylinder 31 sides covering sieve nest 322 is set respectively on sheet 321F, the 321B.
Thus, when threshing operations, be difficult to make the stem etc. of straw to be wrapped in the swivel bearing part that each sieve nest of sieve nest 322 on the female part 32 forms sheet 322A, and soil etc. also is difficult to invade.Therefore, can suppress the reduction of durability that sieve nest forms the swivel bearing portion of sheet 322A, and can prevent that the rotation that sieve nest forms sheet 322A from stopping.
In addition, as shown in figure 12, on sieve nest 322, at least one sieve nest among a plurality of sieve nests formation sheet 322A can be formed sheet 322A and be made for the shape that has protuberance 322Ae at its outer peripheral face.This protuberance 322Ae is along spiralization, and this spiral is consistent with sieve nest formation sheet 322A axis, and this protuberance 322Ae is configured on fore-and-aft direction between the rear and front end portion of sieve nest formation sheet 322A.
Like this, the threshing portion 30 of combine 1, female part 32 also can be following formation: at least one sieve nest forms on sheet 322A and has spiral helicine protuberance 322Ae in a plurality of sieve nests formation sheet 322A of sieve nest 322, and this protuberance 322Ae is consistent with this sieve nest formation sheet 322A axis.
Thus, the sieve nest with spiral helicine protuberance 322Ae forms sheet 322A when threshing operations, utilizes by handling the straw that cylinder 31 is carried, and does not have the sieve nest of protuberance 322Ae to form sheet 322A than other and rotates more.And the sieve nest with spiral helicine protuberance 322Ae forms under the situation of sheet 322A formation more than two, with the rotary speed rotation that has nothing in common with each other.
Therefore, the flow velocity of the straw that can quicken to be transferred also prevents its stagnation, and can realize that power is to the reduction of handling cylinder 21.In addition, can promote grain, suppress to produce dirty grain from the leaking down of female part 32.In addition, can change the angle of straw with respect to the moving direction of handling tooth 313, it is residual to reduce processing.
In addition, in the process chamber 33 that this processing cylinder 31 and female part 32 are set, be provided with a plurality of blades 35 and a plurality of dirt valve 36 that send.A plurality of blades 35 are arranged at the left side side on the top of the body portion 311 that constitute to handle cylinder 31,, are being set up in parallel handling the cylinder axis direction in the scope relative with the front and back central portion from the leading section of body portion 311 with keeping predetermined distance.Dispose these a plurality of blades 35 fore-and-aft direction scope specifically, near the processing tooth 313 that is disposed at the front position from outer peripheral face in body portion 311 near the rearward end of first chaffer 411 of the oscillatory sorting device 41 of sorting portion 40.
Each blade 35 is seen in the front of handling cylinder 31, extending out towards body portion 311 with the mode of handling tooth 313 repetitions, be disposed at rotation that utilize to handle cylinder 31 and handle between the path of tooth 313 rotations, when handling the threshing of cylinder 31 and female part 32 generations, can cut off straw and make it to shorten.Like this, be implemented in the raising to the threshing performance of straw of threshing portion 30, be implemented in the raising of separation performance of first chaffer 411 of 40 pairs of threshing objects of sorting portion.
On the other hand, a plurality of dirt valves 36 that send are provided with in the mode that extends out along left and right directions above the body portion 311 that handles cylinder 31,, in the scope relative, be set up in parallel handling the cylinder axis direction from the leading section of body portion 311 with the rear portion with keeping predetermined distance.The top board face that respectively send dirt valve 36 to be rotatably supported in process chamber 33, variable direction with respect to this processing cylinder axis direction, and at one end portion and bar-like member 37 link, and send dirt valve 36 rotatable linkedly with other.
And the action bars 38 that is arranged at the outside of process chamber 33 is connected with a plurality of dirt valves 36 that send that are disposed at the front position in the dirt valve 36 that send, and utilizes the operation of this action bars 38, and a plurality of dirt valves 36 that send together change its direction.The direction of sending dirt valve 36 utilizes near the guide post 39 that is arranged at it to be fixed in the operating position of hope by action bars 38, keeps suitable direction thus.Like this, can regulate its holdup time according to the condition of straw, be implemented in the raising to the threshing performance of straw of threshing portion 30 at process chamber 33.
As mentioned above, the threshing portion 30 of combine 1 possesses axis processing cylinder 31 that rotatably sets and the female part 32 that is disposed at the below of handling cylinder 31 around fore-and-aft direction.Handle that cylinder 31 possesses the body portion 311 of the drum that extends along fore-and-aft direction and from the outer peripheral face of body portion 311 to handling the outstanding a plurality of processing teeth 313 of cylinder radial outside, tooth 313 be will handle and axis and these processing cylinder 31 consistent and coiling direction unanimities will be configured to, be positioned at the first different spiral 301 of helix pitch and the intersection point of second spiral 302, and see in the front of handling cylinder 31, with the mode configuration process tooth 313 that only has a mutual part to repeat, front or rear with a roughly week of first spiral 301 of setting helix pitch with respect to these processing tooth 313 to the second spirals 302 littlely at the adjacent processing tooth 313 of fore-and-aft direction, constituting of female part 32, possess: framework 321, its have along the outer peripheral face of the body portion 311 that handles cylinder 31 downwards the framework of the front and back of convex curvature form sheet 321F, 321B, form sheet 321F with the framework that is set up in these front and back, framework about between each end about 321B forms sheet 321R, 321L; Sieve nest 322, it has along handling the cylinder axis direction is that a plurality of sieve nests of the tubular that extends of fore-and-aft direction form sheet 322A, the framework in front and back forms between sheet 321F, the 321B and sets up a plurality of sieve nests formation sheet 322A along bending direction every predetermined distance ground.
Thus, when threshing operations, be configured to the tooth 313 of respectively handling of row at fore-and-aft direction to act on the threshing object that is transferred be on the straw in the past with being separated with the time difference in order handling one second spiral 302 in cylinder 31 upper edges.Therefore, can suppress straw and be wound in rope form.In addition, the sieve nest of sieve nest 322 forms sheet 322A and forms cylindricly on female part 32, becomes entangled in sieve nest and forms on the sheet 322A so can suppress straw.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.And, handle tooth 313 and act on the straw as previously mentioned, so can alleviate biography to the overload of the moment of handling cylinder 31, the noise of handling cylinder 31 generations and generation vibration.Therefore, can cosily improve the sensation of taking of the combine 1 that possesses this threshing portion 30.
Threshing portion 30, the female part 32 of combine 1 are made following formation: the framework in the front and back of framework 321 forms on sheet 321F, the 321B axis rotation that forms sheet 322A around this sieve nest and supports each sieve nest of sieve nest 322 freely and form sheet 322A.
Thus, when threshing operations, the sieve nest of sieve nest 322 formation sheet 322A contacts with straw and rotates on female part 32.Therefore, even straw for example contains the straw of washy soybean, also be difficult to be wrapped on the sieve nest 322, be difficult to thrust in the sieve nest 322, promote that grain leaks down from female part 32, can reduce the dirty grain of loss, generation of grain, and can stop the straw delay in flow.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
Threshing portion 30, the female part 32 of combine 1 are made following formation: will see in the front of handling cylinder 31, to be set at adjacent sieve nest formation sheet 322A interval each other at the bending direction of sieve nest 322, these adjacent mutually sieve nests form sheet 322A with opposed in the adjacent leading section while of respectively handling tooth 313 of the fore-and-aft direction of handling cylinder 31.
Thus, when threshing operations, certain sieve nest of sieve nest 322 forms sheet 322A and handles tooth 313 when opposed on female part 32, it is also opposed with processing tooth 313 to form sheet 322A at the adjacent sieve nest of fore-and-aft direction, and these adjacent mutually sieve nests form sheet 322A and always handle the rotation of tooth 313 clamping straw ground with each.Therefore, straw flows with roughly certain speed, can quicken to handle flowing of straw between cylinder 31 and the female part 32.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
The threshing portion 30 of combine 1, processing cylinder 31 are made following formation: the processing tooth 313 that comprises the rear that is positioned at female part 32 in a plurality of processing teeth 313, this processing tooth 313 is set, so that wherein a part repeats for female part 32 in this positive read fortune of handling cylinder 31.
Thus, when threshing operations,, handle tooth 313 at the rear of female part 32 and also cut off the straw that has twined even under the situation of having twined straw.Therefore, promote the discharge of straw, can quicken to handle flowing of straw between cylinder 31 and the female part 32.In addition, can realize passing reduction to the power of handling cylinder 31.Therefore, can carry out threshing operations swimmingly, can realize the raising of threshing performance.
Threshing portion 30, the female part 32 of combine 1 are made following formation: the processing cylinder side outer peripheral face that the sieve nest of sieve nest 322 is formed sheet 322A forms processing cylinder side end face that front and back framework with framework 321 forms sheet 321F, 321B for roughly with simultaneously.
Thus, on female part 32, do not exist the sieve nest of sieve nest 322 to form the front and back framework formation sheet 321F of sheet 322A and framework 321, the step of 321B, so when threshing operations, straw flows on female part 32 swimmingly.Therefore, straw can be suppressed to the entanglement of the sieve nest 322 of female part 32 and thrust etc., the obstruction that produces in threshing portion 30 can be alleviated.In addition, also can alleviate the vibration that produces in threshing portion 30.
The grain portion of portion 30 of combine 1, female part 32 are made following formation: form each sieve nest formation sheet 322A of sieve nest 322 cylindric.
Thus, during threshing operations, straw is difficult to be wrapped on the sieve nest 322 of female part 32.Therefore, can alleviate the obstruction that produces in threshing portion 30.In addition, can realize being difficult to forming sheet 322A damage grain, can realize the reduction of damaged kernel by sieve nest.And, easily make sieve nest form sheet 322A rotation, can promote grain to leak down from female part 32, can suppress the generation of dirty grain.
And threshing portion 30, the female part 32 of combine 1 are also made following formation: form in the front and back of framework 321 framework front and back lining body 323F, the 323B that forms the swivel bearing part of sheet 322A from each sieve nest of handling cylinder 31 sides covering sieve nest 322 is set respectively on sheet 321F, the 321B.
Thus, when threshing operations, the stem of straw is difficult on female part 32 swivel bearing that each sieve nest to sieve nest 322 forms sheet 322A and partly tangles, and soil etc. is difficult to invade.Therefore, can suppress the reduction of durability that sieve nest forms the swivel bearing portion of sheet 322A, can prevent that the rotation that sieve nest forms sheet 322A from stopping simultaneously.
In addition, threshing portion 30, the female part 32 of combine 1 are also made following formation: at least one sieve nest forms on sheet 322A and has spiral helicine protuberance 322Ae in a plurality of sieve nests formation sheet 322A of sieve nest 322, and this protuberance 322Ae is consistent with this sieve nest formation sheet 322A axis.
Thus, the sieve nest with spiral helicine protuberance 322Ae forms sheet 322A when threshing operations, utilizes by handling the straw that cylinder 31 is carried, and does not have the sieve nest of protuberance 322Ae to form sheet 322A with other and compares rotation more.And, form sheet 322A at sieve nest and form under the situation more than two, with different separately rotary speed rotations with helical form protuberance 322Ae.
Therefore, the mobile of the straw that can quicken to be transferred prevents its stagnation, and can realize being delivered to the reduction of the power of handling cylinder 31.In addition, promote that grain leaks down from female part 32, can suppress the generation of dirty grain.In addition, can change the angle of straw with respect to the moving direction of handling tooth 313, it is residual to reduce processing.
In addition, threshing portion 30 particularly its processing cylinder 31 also can followingly constitute, and is explained.
As Figure 13, Figure 14, shown in Figure 15, it constitutes to handle cylinder 31, has body portion 311; The impeller 312, the spiral that are installed on body portion 311 are handled tooth 314; Be installed on the independent process tooth 315 of spiral processing tooth 314 etc.Body portion 311 have with process chamber 33 with the front and back length of degree and form cylindricly, extend along handling the cylinder axis direction.But only the leading section of body portion 311 forms the cylindric of the chamfering different with other parts.
Body portion 311 is with the straw input port 331 of its leading section in the face of process chamber 33, and rearward end disposes in the face of the mode of the straw outlet of process chamber 33.And body portion 311 by being set up in fulcrum 34 supportings of handling the cylinder axis direction, under the situation that this fulcrum 34 is driven in rotation at the power that obtains engine, can be pivot and one rotation with it with fulcrum 34 in process chamber 33.
Impeller 312 forms helical form, is arranged at the outer peripheral face of the leading section of body portion 311.On the other hand, spiral is handled tooth 314 so that the leading section than body portion 311 more is provided with to handling the outstanding mode of cylinder radial outside by the outer peripheral face of rear portion side at the rear of impeller 312.Below, more to describe by the outer peripheral face of rear section outer peripheral face as body portion 311 than the leading section of body portion 311.
A plurality of independent process teeth 315 are provided with to handling the outstanding mode of cylinder radial outside to handle at spiral in the tooth 314 in more detail in the front that spiral is handled the outer peripheral edges portion of tooth 314.In the processing cylinder 31 of this formation, a plurality of independent process teeth 315 form and are equivalent to above-mentioned processing tooth 313, and on this basis, spiral is handled tooth 314 and is arranged between the outer peripheral face of these independent process teeth 315 and body portion 311.
The installation site that spiral is handled tooth 314 and each independent process tooth 315 is according to promptly first spiral 301 and second spiral 302 determine with the spiral of two kinds of the solid line of Figure 13 and double dot dash line outer peripheral face that represent, that be set in body portion 311.First spiral 301 and second spiral 302 are helix pitch as separately coiling direction of following content setting, in the length of the processing cylinder axis direction about a week on the outer peripheral face of body portion 311.
That is, first spiral 301 is set to second spiral 302 all has the axis that extends along the fore-and-aft direction consistent with the axis of handling cylinder 31, and mutual coiling direction is identical, mutually the helix pitch difference.First spiral 301 is set in its helix pitch mode littler than the helix pitch of second spiral 302, around the outer peripheral face multi-turn of body portion 311 ground around.
Second spiral 302 is bigger than the helix pitch of first spiral 301 with its helix pitch, and sets with respect to the very large mode of front and back length of body portion 311, not around the outer peripheral face of body portion 311, reaches the rearward end of body portion 311.And second spiral 302 possesses many, possesses eight in the present embodiment, and second spiral 302 keeps certain compartment of terrain almost parallel and non-intersect each other, only intersects with first spiral 301.
Like this, spiral processing tooth 314 disposes along first spiral 301 at the outer peripheral face of body portion 311.A plurality of independent process teeth 315 are handled tooth 314 at spiral outer peripheral edges portion disposes every equal intervals ground along first spiral 301, and disposes every equal intervals ground along second spiral 302.That is, independent process tooth 315 disposes in the mode of the intersection point that is positioned at first spiral 301 and second spiral 302.At this moment, the quantity that is disposed at the independent process tooth 315 about week of first spiral 301 is the quantity of second spiral 302.
Consequently, in a plurality of independent process teeth 315 the independent process tooth 315 of the independent process tooth 315 of the order configuration in accordance with regulations in certain week of first spiral 301 and the preceding of first spiral 301 or the same order configuration that next is all on the second identical spiral 302 to arrange becoming the adjacent mode of fore-and-aft direction of handling the cylinder axis direction.Simultaneously, as Figure 15, shown in Figure 16, these see in the front of handling cylinder 31 at the adjacent independent process tooth 315 of fore-and-aft direction that mutually it is some circumferentially to stagger at the processing cylinder, that is, make and handle the differently arrangement mutually of the circumferential position of cylinder.
Promptly, in a plurality of second spirals 302 on same second spiral 302, relation for the adjacent independent process tooth 315 of fore-and-aft direction, with respect to the independent process tooth 315 that disposes in certain week of first spiral 301, independent process tooth 315 in the roughly week back configuration of first spiral 301 sees in the front of handling cylinder 31, circumferentially keeps certain spacing bias ground being arranged in processing cylinder direction of rotation upstream side handling cylinder.Thus, these see in the front of handling cylinder 31 that at the adjacent independent process tooth 315 of fore-and-aft direction the mode only there to be a mutual part to repeat disposes mutually.
On this basis, these are handled on the tooth 314 towards the rear repeated configuration, to arrange in the mode that not parallel with the axis of handling cylinder 31 linearity of fore-and-aft direction forms row along one second spiral 302 at spiral at the adjacent independent process tooth 315 of fore-and-aft direction mutually.The row that the independent process tooth of this fore-and-aft direction is 315 groups are being handled circumferentially multiple row configuration at regular intervals of cylinder according to the quantity of second spiral 302.Like this, the outer peripheral face in body portion 311, spiral are handled the installation site of tooth 314 and each independent process tooth 315 by first spiral 301 and 302 decisions of second spiral.
In addition, in the present embodiment, the helix pitch of first spiral of the installation site by will being used to determine the independent process tooth and the helix pitch of second spiral are made as necessarily, make at the leading section interval each other of the adjacent independent process tooth of above-mentioned fore-and-aft direction to equate, but also can be by in any range of the fore-and-aft direction of body portion, both sides or a side's helix pitch is changed than the helix pitch in other scope is big or little.
In addition, make in the present embodiment at the leading section interval each other of the adjacent independent process tooth of the coiling direction of first spiral to equate, but also can make it to shorten, make it to increase by a part that is omitted in the independent process tooth that the first screw winding direction arranges by between the adjacent independent process tooth of the coiling direction of first spiral, appending configuration independent process tooth.
And, under this situation, for female part 32, forming as above-mentioned sieve nest in the supporting structure of sheet 322A, a plurality of sieve nests form sheet 322A and see as shown in figure 16 in the front of handling cylinder 31, and certain sieve nest forms sheet 322A, with form sheet 322A with respect to this sieve nest and form sheet 321F in the front and back framework, the sieve nest that the bending direction of 321B is adjacent forms the leading section of the interval of sheet 322A with certain independent process tooth 315 of processing cylinder 31, with circumferential for to arrange at the interval of the leading section of the adjacent independent process tooth 315 of fore-and-aft direction with the mode of degree at the processing cylinder with respect to this independent process tooth 315.
Therefore, certain sieve nest forms sheet 322A and certain independent process tooth 315 and together is disposed at from the pivot of handling cylinder 31 when handling the first straight line L1 that the cylinder radial outside extends and go up, and forms the framework formation sheet 321F of sheet 322A in front and back with respect to certain sieve nest, the sieve nest that the bending direction of 321B is adjacent forms sheet 322A and also circumferentially departs from predetermined angular to the second straight line L2 that handle cylinder radial outside extension on respect to the first straight line L1 at the processing cylinder with being disposed at from the pivot of handling cylinder 31 at the adjacent independent process tooth 315 of fore-and-aft direction with respect to certain independent process tooth 315.
Promptly, when certain sieve nest forms sheet 322A and disposes in the opposed mode of leading section with certain independent process tooth 315 of handling cylinder 31, form the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B with respect to certain sieve nest and form sheet 322A also to form with disposing in the opposed mode of leading section of the adjacent independent process tooth 315 of fore-and-aft direction with respect to certain independent process tooth 315.In other words, mutually adjacent sieve nest form sheet 322A with the leading section of each adjacent independent process tooth 315 of the fore-and-aft direction of handling cylinder 31 simultaneously opposed mode dispose and form.
At this moment, see in the front of handling cylinder 31, handle each independent process tooth 315 of cylinder 31 and set at the circumferential interval of processing cylinder of the adjacent independent process tooth 315 of fore-and-aft direction as previously mentioned roughly the samely with respect to this independent process tooth 315, so each sieve nest forms sheet 322A and forms sheet 322A with respect to this sieve nest and sets at the circumferential interval of processing cylinder of the adjacent sieve nest formation sheet 322A of the bending direction of framework formation sheet 321F, the 321B of front and back also roughly the samely.Thus, a plurality of sieve nests formation sheet 322A equally spaced arrange at the framework formation sheet 321F of front and back, the bending direction of 321B.
In addition, in the present embodiment, forming sheet interval each other the same with the leading section interval each other of independent process tooth with sieve nest is that equally spaced mode is arranged a plurality of sieve nests formation sheets, but change corresponding to the leading section interval each other of independent process tooth, sieve nest forms sheet interval each other also can form the change of sheet each interval greatly with the sieve nest of a part, the mode unequal interval ground that remaining sieve nest formation sheet interval each other diminishes is arranged.
As mentioned above, following formation is made by the threshing portion 30 of combine 1: also possess between the outer peripheral face of independent process tooth 315 and body portion 311 to handling the outstanding spiral of cylinder radial outside and handle tooth 314, handle tooth 314 along first spiral, 301 configuration spirals, this first spiral 301 is consistent with these processing cylinder 31 axis.
Thus, when threshing operations, to act on the threshing object that is transferred be on the straw in the past with being separated with the time difference in order handling each independent process tooth 315 that one second spiral 302 in cylinder 31 upper edges is configured to row at fore-and-aft direction.Therefore, can suppress straw and be wound in rope form.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.And independent process tooth 315 as above-mentioned acting on the straw are so can alleviate biography to the overload of the moment of handling cylinder 31, the noise of handling cylinder 31 generations and generation vibration.Therefore, also can cosily improve the sensation of taking of the combine 1 that possesses this threshing portion 30.
And, threshing portion 30, the female part 32 of combine 1 are made following formation: the front at processing cylinder 31 is seen, forms sheet 322A sieve nest adjacent with the bending direction that is set in sieve nest 322 in opposed mode of the leading section while of each adjacent independent process tooth 315 of the fore-and-aft direction of handling cylinder 31 with these adjacent mutually sieve nests and forms sheet 322A interval each other.
Thus, when threshing operations, certain sieve nest of sieve nest 322 forms sheet 322A and independent process tooth 315 when opposed on female part 32, it is also opposed with independent process tooth 315 to form sheet 322A at the adjacent sieve nest of fore-and-aft direction, and these adjacent mutually sieve nests form sheet 322A and always rotate with each independent process tooth 315 clamping straw.Therefore, straw flows with roughly certain speed, can quicken to handle the flow velocity of the straw between cylinder 31 and the female part 32.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
In addition, in the threshing portion 30 of this combine 1, female part 32 also can followingly constitute, and is described.
As shown in figure 17, in female part 32, being set up in parallel in handling cylinder circumferentially is that two of left and right directions are cut apart female part 320 so that part left framework that the right framework of the framework 321 of cutting female part 320 forms sheet 321R and part the framework 321 of cutting female part 320 on the right side on the left side and form sheet 321L face state of contact and link.Framework 321 as the above-mentioned formation of respectively cutting apart female part 320.
Also shown in Figure 18 (a), about cut apart the left framework that parts the framework 321 of cutting female part 320 on the right side in the female part 320, that handle cylinder direction of rotation upstream side and form sheet 321L and have vertical portion 321La and horizontal part 321Lb, with horizontal part 321Lb from the upper end of vertical portion 321La towards forming the mode that sheet 322A side extends and form anti-L word shape handling the circumferentially adjacent sieve nest of cylinder.
Left side framework forms sheet 321L and forms sheet 321F binding in the right side and the preceding framework of its leading section, and the right side of portion and after-frame bodily form 321B in blocks links in its back-end.At this linking part, the vertical portion 321La that left framework is formed sheet 321L is fastening with the left part that the framework of front and back forms sheet 321F, 321B, and left framework forms the horizontal part 321Lb mounting of sheet 321L on the left part of framework formation sheet 321F, the 321B of front and back.
In addition, left framework form sheet 321L in its left side can with part the right framework of cutting female part 320 on the left side and form sheet 321R and engage.At this graft union, the vertical portion 321La that left framework forms sheet 321L contacts with the vertical portion 321Ra face that parts the right framework formation sheet 321R that cuts female part 320 on the left side in the scope of front and back.This right side framework forms sheet 321R and left framework formation sheet 321L left-right symmetry constitutes much the samely.
And, pole shape parts 326 form in left framework the right side side of vertical portion 321La of sheet 321L and horizontal part 321Lb under form sheet 322A with sieve nest and dispose abreast, the framework before and after being set up in forms between sheet 321F, the 321B.These pole shape parts 326 form the continuous mode in the right side of horizontal part 321Lb of sheet 321L to the right side of this horizontal part 321Lb with its right side outer peripheral face and left framework, it is outstanding some promptly to handle cylinder direction of rotation upstream side.Like this, form the adjacent sieve nest that is provided with on the sheet 321L with handling cylinder direction of rotation upstream side in left framework and form the opposed curved face part 327 of sheet 322A.But, replacements such as the enough cylinder-like parts of pole shape parts energy.
Perhaps, shown in Figure 18 (b), left framework forms the horizontal part 321Lb of sheet 321L at its left and right directions middle part, along to handling drum shaft to being the broken curve that fore-and-aft direction extends, removes end roughly bending at right angles towards the below of front and back.Like this, left framework forms the adjacent sieve nest that sheet 321R was provided with and handled cylinder direction of rotation upstream side and forms the opposed bight 328 of sheet 322A.
Promptly, it constitutes female part 32, about cut apart in the female part 320, handle framework 321 that parting on the right side of cylinder direction of rotation upstream side cut female part 320, be positioned to form sieve nest formation sheet 322A opposed curved face part 327 or the bight 328 adjacent with handling cylinder direction of rotation upstream side be set on the sheet 321L with the left framework that parts the binding side of cutting female part 320 on the left side.
Thus, during threshing operations, cut female part 320 from handling cylinder direction of rotation upstream side downstream during side flow by the straw of handling cylinder 31 threshings parting on the right side, contact with curved face part 327 or bight 328, being difficult to lash forms on the sheet 321L, particularly on its horizontal part 321Lb in the left framework of framework 321.Therefore, when straw is the soybean straw, can reduce the dirty grain of soybean.In addition, the straw lash be can suppress to produce and the obstruction of cutting apart female part 320 (female part 32) that causes on the sheet 321L, the straw lash forms the threshing portion 30 that causes on the sheet 321L in right framework integral body obstruction formed in left framework.The raising of the operating efficiency in the time of consequently, can realizing threshing operations.
Utilizability on the industry
The threshing section of united reaper of the present invention so can carry out smoothly threshing operations, can realize the raising of threshing performance because straw can not be wound in rope form, so useful on the industry.
