[0017]
Next, FIG. 6 shows a plan view of a side divider (20) which is a main part of the present invention. The side divider (20) is formed in an arc shape in a plan view, and includes a front side divider (58) and a rear side divider (60) via a bracket (76) which is a connecting portion. The side divider (20) is a member that is provided on the left side of the machine body and functions to protrude outside the machine body during mowing work and to prevent uncut crop culms from being taken into the machine body.
[0018]
The front side divider (58) is extendable and retractable, and the front end is attached to the frame of the weeding board (9) so as to be rotatable around a vertical axis, and the rear end is turned around the vertical axis around the bracket (76). The left and right side dividers (58) and (60) are movably mounted and connected to the front end of the left body divider (60), and the left and right sides of the front and rear side dividers (58) and (60) connected to the left side of the fuselage adjust the horizontal position by the expansion and contraction of the arm (75). It is configured to do so.
Further, a ring portion (78) at the rear end of the body left side divider (60) is slidably fitted on a guide rail (77) fixed to the lower surface of the body left side in the front-rear direction.
[0019]
With the above configuration, the side divider (20) projects and is housed by the expansion and contraction of the arm (75). In the present invention, a gas damper as an opening / closing mechanism is used for the arm and provided in another part on the combine. Operation from the operating means.
7 is a transparent plan view of the arm (75) according to the present invention, FIG. 8 is a transparent front view of the same, FIG. 9 is a cross-sectional transparent view of the arm (75) from the fuselage side, and FIG. 20) is a cross-sectional transmission view from the side, and has the following structure.
[0020]
That is, an outer pipe (80), which is a square pipe body at the outermost part, and an inner pipe (81) having a U-shaped cross section (open surface is lower) are slidably inserted into the outer pipe (80). 81) is longer than the outer pipe (80), and therefore protrudes from the outermost end (80a) of the outer pipe (80) even in a contracted state. The outer pipe (80) also forms a square pipe by combining the upper U-shaped body (800) and the lower plate (801).
A bracket (76) is attached to an outermost end of the inner pipe (81) with an end plate (81a) interposed therebetween, and supports the front / rear side dividers (58) and (60).
[0021]
Inside the lower surface of the outer pipe (80), two parallel bearings (82) (82) protruding in a mountain shape are arranged, and the cylinder part (83) of the gas damper is supported by the shaft (84). ing. Further, a fixing plate (85) that conforms to the inner shape of the inner pipe (81) is attached to the inside of the lower surface of the outer pipe (80), and the upper part of the fixing plate (85) branches into two branches. Since the cylinder part (83) is configured to be sandwiched, it is possible to effectively support the cylinder part (83) while absorbing the vibration at the time of driving.
[0022]
On the other hand, a pulley support member (87) bent in a substantially U-shape is fixed to a rod portion (86) of the gas damper with a nut (88). At the wide portion (87a) of the opposing surface of the pulley support member (87), the rod portion (86) and the inner pipe (81) slide integrally with each other by adhering to the inside of the inner pipe (81).
A small end plate (87b) of the pulley support member (87) is externally fitted with a tip plate (89) having a U-shaped cross section with a bolt (90), and the bolt (90) is fitted inside. Constitutes the rotation axis of the pulley (91) disposed in the first position.
[0023]
The body side end (80b) of the outer pipe (80) is welded and fixed to an L-shaped bent fitting (92), and the fixed fitting (92) is fixed to the combine body frame.
The fixed metal fitting (92) is provided with a wire conducting pipe (94) for conducting a wire (93) from the outside at the bent portion (92a), and the wire (93) is fixed inside the upper surface of the inner pipe (81). The wire is wound around a pulley (91) through the wire conducting tube (95).
The end of the wire (93) is fixed to the inside of the lower surface of the outer pipe (80) with a wire fixing bracket (96). From the above configuration, when the wire is pulled, the inner pipe (81) becomes the outer pipe (80). When the wire is released, the inner pipe (81) is extended by the action of the gas damper.
[0024]
According to the above configuration, when pulling a wire manually by using a pulley, the operation load can be reduced to の of the actual load without using a link, and the tension can be increased by using a double stroke of the actual stroke of the gas damper. Since the gas is moved out and stored, the change in the spring force caused by the gas damper can be suppressed with the length of the stroke.
Further, since the external force does not directly act on the gas damper due to the double structure of the outer pipe and the inner pipe, damage to the gas damper can be prevented.
[0025]
The arm (57) of the side divider (20) of the present invention is not limited to the above-described configuration. For example, the rod portion (86) of the oil damper is directly connected to the inner pipe (81) and directly expands and contracts without using a pulley. It may be configured as follows.
Further, a configuration may be employed in which the bracket (76) is displaced by the direct expansion and contraction of the cylinder without using a double pipe structure.
[0026]
Further, the wire (93) is pulled by using the operating means described below. FIG. 11 is a side view of a handle mechanism as an operation means, FIG. 12 is a plan sectional view thereof, and FIG. 13 is a rear sectional view thereof.
The handle mechanism has a pulley (102) and a handle shaft (103) rotatably fitted on a rotation shaft (101) that is fixed to the base plate (100) and protrudes from the plate surface.
The wire (93) can be wound around the pulley (91), and the end of the wire is fixed on the pulley (91).
[0027]
A handle plate (104) is fixed to the tip of the handle shaft (103), and a lever (105) projects from the handle plate (104).
A locking member (07) having a locking projection (106) is provided on the handle shaft (103), and is urged in a certain direction by a spring (108). Interference prevents the pulley from rotating more than a predetermined amount.
[0028]
With the above operation means, the lever (105) can be rotated to pull the wire (93). Conventionally, the operator gets off the seat and manually extends and stores the side divider (20). However, this can be done by lever operation.
These operating means can be provided, for example, on the side column (31) beside the seat (30) of the driving operation unit (4) so that the operator can operate with one hand while sitting. According to this configuration, since the position is close to the user's hand, the operation is simple, and especially when the storage of the side divider (20) is forgotten, the storage operation can be performed immediately.
[0029]
In addition, the operating means can be arranged at an arbitrary part of the combine. For example, the operating means is provided on the seat (30) side of the reaper (3) (for example, the position (32) in FIGS. The operation of the lever (105) may be performed by slightly leaning the body. In this arrangement place, the operation relating to the reaping operation can be concentrated on the reaping section (3), so that the reaping can be easily performed.
Further, the operation means may be provided at the front of the threshing unit (5) (for example, at the position (33) in each drawing). Even in this position, the operation can be performed while the operator is sitting, and good workability can be obtained.
[0030]
In the above, the opening / closing mechanism may be constituted by an extensible member simply using an air cylinder, a motor or the like without using the gas damper. Also, the present invention can be configured not as a wire operation but as a member for electrically driving an opening / closing mechanism, and as an operating means as a switch for turning on / off the operating means.
[0031]

Since the side divider is stored and extended by the operating means for operating the mechanism, there is no need for the operator to step down from the combiner and operate the side divider, thereby improving work efficiency and quickly responding to forgetting to store.
[0032]
According to the second aspect of the present invention, the side divider is connected at a variable angle between the front side and the rear side via the connecting member, and the front end is pivotally supported at the front of the combine, while the side divider is rearward at the rear. In the configuration in which the end is slidably supported, the fulcrum of the opening / closing mechanism can be the connection member, so that regardless of the presence or absence of the cutting slide or the state of the left slide and the right slide, a function of weeding the rod is provided. This contributes to improving work efficiency.
[0033]
According to the third aspect of the present invention, since the opening / closing mechanism is provided with a cushioning member for buffering the force in the direction of expansion and contraction, when it collides with a ridge or the like while projecting at the operation position of the side divider, the storage position is naturally increased. , Which contributes to prevention of breakage of the side divider.
[0034]
According to the fourth aspect of the present invention, since the operating means is provided in the reaping unit, the operation relating to the reaping operation can be concentrated on the reaping unit, and the reaping can be easily performed. Also, operability is improved.
