Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a knotting device for a knotter that can be mounted on a combine or the like.
[0002]
[Prior art]
Conventionally, as a knotter that is attached to the rear of the threshing part of the combine and aligns and binds the threshed stalks (hereinafter referred to as “waste”) while aligning the roots while aligning them with the stock alignment plate provided in the rooting device. Is proposed in Japanese Patent Laid-Open No. 9-271244.
[0003]
[Problems to be solved by the invention]
However, the stocker aligning plate of the knotter as shown in the above publication generally supports the stem stock supply side and the binding discharge side with a support link member having a stock striking structure, or reduces the stock aligner plate itself. For the purpose of illustration, a thin steel plate is used.
[0004]
Therefore, when the stock base part of the waste is struck with the stock stock alignment plate in the middle of the binding discharge path, the binding part moves suddenly even when the binding width is exhausted, causing a binding failure. There is a fault that is easy to do. In addition, if the waste is clogged or stagnated in the middle of the bundling section or on the bundling discharge side, the stock gathering plate forcibly pushes the clogged waste, which causes significant damage to the stock end of the waste. In addition, there are problems such as deforming or damaging the stock gathering plate and its stock strike structure.
[0005]
[Means for Solving the Problems]
Roots orientation device of the knotter according to the present invention has been made to solve the above problems, bundling discharged united by the bundling unit 4 Kuki稈fed in landscape orientation from Kuki稈supply side In a knotter provided with a plant stock aligning plate 60 that strikes and aligns the stock ends of the stems to be bundled on the stock base side of the binding device 4a that discharges to the side, the stock stock aligning plate 60 is passed through the stock stock hitting structure 6a. While supporting the stock stock so that it can be struck, the tip end side of the stock stock aligning plate 60 on the binding discharge side is elastically deformed by its elastic force when stock stock is struck, or elastic to the stock stock by the elastic force of the spring. It is characterized in that it is formed so as to be in contact with .
[0006]
As the structure of the stock share aligning plate 60, the following can be applied.
a) The whole stock gathering plate 60 is formed by using a thin plate-like body that is relatively easy to bend, so that it is easily bent as a whole.
b) The part pivoted or fixed to the stock beating structure 6a is hardened, and finally the softening is made so as to go to the tip part where the stock is hit.
c) A portion that is pivotally attached or fixed to the stock beating structure 6a is formed of a relatively hard thin plate or the like, and a thin plate is pivotally attached to the tip of the plate, and an elastic force such as a spring is attached to the tip. There is a structure in which a strain is elastically brought into contact with a root aligning movement by restoring the original state by acting.
[0007]
Therefore, the stock aligning plate 60 uses a thin metal plate having an elastic force, a plastic plate made thin and easily bent, or a structure structured so as to elastically deform the tip portion. can do.
[0008]
In addition, the stock aligning plate 60 is pivotally attached to the stock striking structure 6a on the stem supply side and the discharge side is a free end, and the free end performs a movement like a fish tail fin to provide a striking force. It is mainly configured to give.
[0009]
Alternatively, there is a structure that is arranged along the side of the stem discharge path 1a and is configured to reciprocate so as to strike the root of the stock substantially perpendicular to the discharge path 1a. The front end of the original aligning plate 60 must be configured to have a function of giving a required striking force to the stock holder.
[0010]
By forming the stock stock aligning plate 60 so as to be elastically deformable as described above, it is possible to sufficiently perform the stock stock stock aligning action, and not to give more impact than necessary. It is possible to avoid bad binding and significant damage to the stock edges. Further, unnecessary force is not applied to the stock gathering plate 60 and the stock stock striking structure 6a.
[0011]

When the waste is fed to the converging position in the bundling discharge path 1a while the stock ends are beaten and aligned by the root aligning device 6 as will be described later, the bundling is converged to a predetermined amount. The binding string 4b is supplied to the bundling mechanism 12 (FIG. 5) side of the knot 4 provided above by the needle 11 (FIG. 4) of the needle 3 provided below the discharge path 1a. The bundling mechanism 12 is operated by sensing the bunch amount pressure of the door 30 and operates in conjunction with the needle 11. After bundling the stock of the waste collected using the bundling string 4b, the bundling mechanism 12 is moved to the knot 4 side. By the provided sweeper 13 etc. Te has a structure to release the bunched discharge straw outside.
(Bundling device)
Next, the structure of the bundling device 4a will be described with reference to FIGS.
[0013]
A needle part case 16 provided with the needle part 3 is located below the bundling discharge path 1a of the waste in the knotter 1 provided with the knotter frame 14, and a knot part case provided with the binding part 4 above. 17 are provided. The needle portion case 16 and the knot portion case 17 are integrally connected and fixed by a connecting frame 16a that is curved in a U shape so that the waste tip side can pass toward the waste tip side (FIG. 2). 7).
[0014]
The needle case 16 is attached to the horizontal frame 14a via a slide frame 18 that slidably holds the lower horizontal frame 14a, and the knot case 17 is also attached to the upper horizontal frame 14b via a slide frame 19, respectively. It is supported so as to be slidable to the left and right with respect to the knotter frame 14 (lateral frames 14a, 14b) (FIGS. 4, 5, 7, 8).
[0015]
The knotter frame 14 is formed by connecting the left and right of the upper and lower horizontal frames 14a and 14b with a plate-like support frame 15 and a bowl-like support frame 15a to form a rectangular rigid body frame. By supporting the base side of a knotter drive shaft 15b of a hexagonal bar-like rod driven to rotate from the machine C side (FIG. 8), the needle case 16 is slidably engaged with the knotter drive shaft 15b ( 5), the transmission accompanying the movement of the bundling device 4a in the longitudinal direction can be performed smoothly all the time.
[0016]
That is, since the knotter drive shaft 15b is provided at an intermediate position between the horizontal frames 14a and 14b, the bundling device 4a can be smoothly slid in the left-right direction and can be transmitted well.
[0017]
Further, a string basket 40 that accommodates a string ball capable of feeding the binding string 4b is detachably and integrally attached to the lower part of the needle portion case 16 of the binding device 4a.

[0018]
When the handle 42 is operated to rotate the knotter moving screw 43 in the forward direction, the bundling device 4a causes the slide frames 18 and 19 to slide leftward on the horizontal frames 14a and 14b, and binds the waste side closer to the stock side. When the knotter moving screw 43 is reversed, the bundling device 4a is slid rightward so that the waste side of the waste can be freely bound by the bundling unit 4. .
[0019]
Further, the knotter moving screw 43 is laid along the vicinity of the lower side of the rear side frame 14a at a lower position than the side frame 14b on the threshing device side (front side), so that the weight of the bundling device 4a Since the notch moving screw 43 pushes the vicinity of the horizontal frame 14a that mainly receives the baffle, the bundling device 4a is smoothly slid without being squeezed by the upper and lower horizontal frames 14a and 14b and dropped from above. There is a feature that it is possible to prevent direct contact with the straw scraps and the knotter moving screw 43 (FIG. 5).
(Root alignment device)
Next, as shown in FIG. 2, the root aligning device 6 is provided on the left side (stock side) of the bundling device 4a (the bundling portion case 17 and the needle portion case 16) in the knotter frame 14, which will be described later. It is provided on the knotter frame 14 through the root alignment position adjusting structure 7 so as to be movable left and right so that the stock ends can be properly beaten and aligned with each of the lengths and binding positions. Further, at each root alignment position, it is swung by the strainer striking structure 6a (FIG. 7), and the strainer alignment plate 60 is swung in the direction of the slimming of the waste so that the waste stock is beaten to align the waste. I am doing so.
[0020]
The bundling device 4a and the root aligning device 6 have the above-described structure, and after the harvested cereals conveyed to the threshing device C for threshing are threshed, the waste bundling discharge path 1a of the knotter 1 The stock ends are beaten and aligned by the root aligning device 6 and focused on the converging position in the binding discharge path 1a on the basis of the stock, and then the binding device 4a binds and discharges the waste. Work is done.
[0021]
At this time, the binding position can be changed by sliding the binding device 4a to the left and right along the knotter frame 14 (lateral frames 14a, 14b) as described above.
[0022]
At this time, a binding string 4b (FIG. 4) for binding fed from a string basket 40 that accommodates the string balls supported below the knotter frame 14 is connected to the needle 11 of the needle portion 3. The binding string 4b is supplied to the binding mechanism 12 by the rotation of 11, and is linked with the action of the binding unit 4 so that the waste is bound.
(Knotter structure and action)
Next, a detailed configuration of each part of the above knotter 1 and its operation effect will be described.
[0023]
First, the shape and the related structure of the culm guide member 5 and the root stock aligning plate 60 of the root aligning device 6 provided near the stock side will be described. As shown in FIGS. 3 to 7, the stalk guide member 5 forms a binding discharge path 1a having a substantially downward inclination from the rear end side of the waste cutter B to the needle case 16 of the binding device 4a. 3. Stablely support the stock side and the ear side of the waste fed from the shoot supply side (hereinafter referred to as the upper side) on the left and right sides of 3 and smoothly guide and discharge to the binding discharge side (hereinafter referred to as the lower side) I have to.
[0024]
That is, as shown in FIG. 6, the stalk guide member 5 has a flat supply guide surface 50 that is inclined downward on the upper hand side, and discharges on both sides of the needle 11 on the lower hand side continuous to the supply guide surface 50. Concentrated stem guide surface 51 that guides it in a substantially horizontal direction visually, and is connected to the supply guide surface 50 at substantially the same angle of inclination through the stock side of the stem portion guide surface 51 and the stepped portion 52. The stock side down guide surface 53 is formed with a stock source aligning plate 60 having a shape to be described later on the stock side down guide surface 53 via the root alignment position adjusting structure 7 (FIG. 7). In the direction), and can be oscillated by a swing amount (striking amount) set by the stock striker structure 6a at the movement adjustment position (each root position). .
(Stock plate)
The stock aligning plate 60 of the root aligning device 6 has a sufficient shape from the side of the binding discharge path 1a with its lower edge extending rearward along the stock side flow guide surface 53 in the shape of the side view. And a broad plate-like body having a substantially triangular shape with a width close to the inclined surface on the lower side from the upper side of the stock side flow guide surface 53. The stock share aligning plate 60 is formed of a flexible plastic thin plate (elastic deformation member) having elasticity as a whole.
[0025]
As shown in the plan view of FIG. 7, the stock-source aligning plate 60 is bent with the upper side facing outward, and from the uppermost side portion of the outer side to the focusing stem portion guide surface 51 (FIG. 6). A mounting reinforcing frame 61 is fixed to the middle part of the mounting, and the upper side part of the mounting reinforcing frame 61 is attached to the vertical hitting shaft 62 of the stock hitting structure 6a. In the above, the stock end of the waste fed on the pedicle guide member 5 by a predetermined amount of rocking (beating amount) with the hitting shaft 62 as a swinging fulcrum set by the stock base hitting structure 6a, Strike and align while guiding from the upper side.
[0026]
As a result, at the position of the bundling portion 4 on the focusing stem guide surface 51 where the waste is supported by a gently inclined surface, the root gathering operation of the predetermined amount of the waste is performed in the shape of the stock stock aligning plate 60. With elasticity, it is possible to perform alignment and effortlessly, so that good binding and discharge can be performed smoothly.
[0027]
The stalk guide member 5 and the root aligning device 6 configured as described above have excellent characteristics during the binding operation of the following waste.
[0028]
That is, the converging stem guide surface 51 that is substantially horizontal in a side view and the stock-side flow guide surface 53 that is inclined downward expands in a substantially triangular shape from the upper side to the lower side in the waste feed direction. Therefore, the bundling can be smoothly performed in a state in which the stem portion of the waste that is focused more and more toward the lower side is stably supported at the position of the bundling portion 4.
[0029]
Further, the stock side whose focusing volume increases remarkably as it reaches the lower side is configured to be supported on the stock-side flow guide surface 53 by the drop of the stepped portion 52 that sequentially expands. The stock end aligning plate 60, which is erected so as to wrap with the stepped portion 52 toward the lower side as viewed from the side in the side view above, can be elastically deformed, and prevents the alignment leak at the wide rear part, It can be beaten.
[0030]
The stock-side flow guide surface 53 can be slid out of the machine without stagnating debris, such as a fish hook or weed, which is generated on the stock side by a series of inclined surfaces.
[0031]
Further, the stock aligning plate 60 is formed of an elastically deformable member made of a plastic thin plate or the like that is restored after being deformed by its elasticity at the time of hitting, and a rigid attachment by the mounting reinforcing frame 61 to the hitting shaft 62 is bound to a binding portion. 4 up to the upper side and the lower side to the free end.
[0032]
Therefore, the rear side of the stock gathering plate 60 having a large swinging amount with the hitting shaft 62 as the center can be greatly elastically deformed, and when clogging or the like occurs at the rear end of the bundling discharge path 1a, Damage caused by striking the stock end, such as large refraction at the stock end, breakage of the stock source aligning plate 60, deformation of the components of the root aligning device 6 such as the mounting reinforcement frame 61 and the hitting shaft 62, Can be avoided.
[0033]
In addition, the stock gathering plate 60 strikes and aligns the stock end while buffering the stock end with the elastic force of the midway portion of the waste gathering in the binding portion 4, so that the waste in the binding is tied. There is no need to move rapidly, and it is possible to satisfactorily perform a rooting operation that prevents the occurrence of binding errors.
(Position adjustment structure 7 and stock beating structure 6a)
Next, the above-described root alignment position adjustment structure 7 and stock-tapping structure 6a provided in the root alignment device 6 will be described with reference to FIGS. 2 and 6 to 11.
[0034]
First, in the stock striker structure 6a, a support arm 64 that supports a strike shaft 62 that attaches the stock share aligning plate 60 via a mounting reinforcing frame 61 is rotatably supported on a support shaft 63 that is erected from the side of the horizontal frame. At the tip of this, it is pivoted upright. The operating piece 65 that is integrally protruded to the base side of the hitting shaft 62 is connected to the tip end portion of the swing operating rod 66 that is pivotally supported by the support shaft 63 so that the middle portion can swing. Thus, a 4-bar parallel link is formed.
[0035]
The other end side of the swing operation rod 66 is connected to the reciprocating drive rod 66a from the knotter drive shaft 15b (FIG. 8) side. Accordingly, in a state where the support arm 64 is positioned and fixed by the root alignment position adjusting structure 7, the swinging reciprocating motion around the support shaft 63 of the swinging operating rod 66 is struck through the link rod 67 and the operating piece 65. A stock source aligning plate 60 is oscillated and oscillated by a predetermined amount around the shaft 62 so that the stock side ends can be beaten and aligned.
[0036]
In the illustrated example, as shown in FIG. 12, the operating piece 65 has a connecting hole 65 a for axially attaching a connecting pin 67 a for attaching the link rod 67, and the phase is different in the front and rear direction around the hitting shaft 62. A plurality of link rods 67 are selectively connected to the plurality of connection holes 65a via the connection pins 67a, so that the mounting positions of the two are made different as shown in FIGS. Then, the working angle and amount of swing of the stock aligning plate 60 can be freely selected, and the root aligning operation is performed by appropriately performing the tapping aligning operation appropriately adapted to the nature of the discharged waste to be fed, the heel length posture at the time of binding, etc. Can be performed satisfactorily.
[0037]
Next, the root alignment position adjusting structure 7 will be described.
[0038]
This root alignment position adjusting structure 7 connects the support arm adjusting portion 7a for positioning the support arm 64 of the stock share aligning plate 60 so as to be rotatable around the support shaft 63, and the bundling device 4a and the stock share aligning plate 60. It is composed of a root aligning plate linkage adjusting mechanism 7b that is connected by a member 70 and causes the stock aligning plate 60 to be moved left and right as the binding device 4a moves in the slimming direction (FIG. 7).
[0039]
The support arm adjustment portion 7a (FIG. 11) is a support in which an adjustment plate 64a formed integrally with the base portion of the support arm 64 is provided with an arc-shaped adjustment hole 64b centered on the support shaft 63 standing on the horizontal frame. The mounting bracket 14c (FIG. 10) having the shaft 63 is provided so as to be capable of positioning and fixing via an adjusting screw 64c.
[0040]
Further, the root aligning plate linkage adjusting mechanism 7b has a connection bracket 71, a connection pin 71a provided at the tip of the support arm 64, and a binding device 4a side in a state where the adjustment screw 64c of the support arm adjustment unit 7a is loosened. By connecting the connecting pin 72a of the connecting bracket 72 so that the length can be adjusted and separated by the connecting member 70, for example, the binding device 4a is moved to the left side from the binding position of the binding device 4a shown in FIG. 8 is moved to the stock side-side binding posture shown in FIG. 8, the stock source aligning plate 60 has a length set by the connecting member 70, and the support arm 64 rotates counterclockwise around the support shaft 63. Move. In the position shown in the figure, the stock element aligning plate 60 can be operated by the stock element striking structure 6a.
[0041]
Accordingly, when the root aligning device 6 and the bundling device 4a are connected and moved by the connecting member 70 of the root aligning plate linkage adjusting mechanism 7b, the bundling portion 4 can focus on various kinds of straw (stalks) having different lengths. It is possible to satisfactorily perform the rooting work by identifying and aligning the stock end side of a certain length from the bundling position, and the slide movement (positioning adjustment) of both can be performed using the knotter moving screw 43 (FIG. 7). It can be done with simple operations such as turning.
[0042]
Further, in the structure as described above, as shown in FIG. 7, when the connecting bracket 72 on the bundling device 4a side is provided at an appropriate position of the connecting rod 73 for connecting the slide frames 18 and 19 in the front-rear direction, the stock stock is aligned. The force for following the plate 60 can be shared and supported by the slide frames 18 and 19.
[0043]
In addition, the installation structure of the root alignment plate linkage adjusting mechanism 7b can be a high-performance one with a simple and inexpensive configuration, and the vibration of the root alignment operation of the stock alignment plate 60 can be directly applied to the bundling device 4a. There is a feature that it can be suppressed without telling.
[0044]
Further, the connecting member 70 can be adjusted from the binding position by the binding portion 4 when the distance between the connecting pin 71a and the connecting pin 72a can be adjusted by, for example, a slide adjusting means or a turnbuckle means as shown in FIG. The length to the end can be set easily and freely.
[0045]
When the connection of the connecting member 70 of the root aligning plate linkage adjusting mechanism 7b is released by the attaching / detaching means, the stock aligning plate 60 is supported by the adjusting hole 64b and the adjusting screw 64c of the supporting arm adjusting portion 7a. Since it can be independently moved and fixed at a desired root alignment position around 63, for example, the tip side binding that separates the stock tip aligning plate 60 and the binding portion 4 as much as possible and binds the waste tip portion Etc. are advantageous in that they can be freely selected.
[0046]
【The invention's effect】
As described above, according to the rooter aligning device of the knotter of the present invention, the free end portion of the stock aligner plate 60 is formed by elastically deforming the front end side on the binding discharge side. Since the stems are beaten and arranged with elasticity, it is possible to perform rooting work that prevents damage to the stem ends of the stems.
[0047]
Further, when a binding clogging or the like occurs in the binding portion 4, the free end portion of the stock stock aligning plate 60 swings greatly, so that it is possible to prevent deformation or the like of components such as the stock stock hitting structure 6 a.
[0048]
In addition, the strainer aligning plate 60 is elastically deformed and swung at a portion facing the binding portion 4, so that when the stem stems that are focused on the binding portion 4 are beaten and aligned, the strain force is caused by the elastic force. Since the ends are cushioned and softly tapped, the binding by the binding portion 4 can be performed satisfactorily.
[0049]
Further, in the case where the stock former aligning plate 60 is formed of a plastic thin plate body, the stock original aligning plate 60 is attached and supported by the attachment reinforcing frame 61 from the hitting shaft 62 of the stock original hitting structure 6a, so There is an advantage that it is possible to provide a root aligning device 6 that can be elastically deformed freely without difficulty with its bundling discharge side as a free end while stably supporting as a rigid structure.
