[0001] The present invention relates to a combine and
The present invention relates to a support restricting rod used for this.

[0002]

2. Description of the Related Art A horizontal auger is mounted on a vertical auger which is rotatably operated in the vicinity of the rear side of a grain tank disposed beside a threshing / sorting unit, and has a relatively low tip height. There is a combine equipped with a grain discharging device which is mounted in such a state that it can be tilted up and down.

In this type of combine, in a state where the horizontal auger is appropriately swung around the vertical auger, the height of the grain discharge port at the tip thereof is set to, for example, about 1 m or less from the running surface of the machine. The tip-up ascending angle is made small, and under this condition, the worker is used to drop the paddy discharged from the grain discharge port into the paddy bag placed on the running surface.

[0004] The above-mentioned lateral auger is formed to be long in relation to the body length of the combine and is moved over a wide range, so that it may collide with other objects existing around the body and prevent this. As an example, for example, Shokai 6
There is a technique as shown in Japanese Patent Application Laid-Open No. 3-119333.

Problems to be Solved by the Invention
The technique disclosed in Japanese Patent No. 119333 is useful for avoiding collision between the lower surface of the horizontal auger and other objects other than the combine, but the lower surface and the left and right side surfaces of the horizontal auger collide with the body parts other than the horizontal auger. It is not suitable for avoiding strictly.

In view of the above circumstances, the present invention changes the inclination angle of the horizontal auger to reduce the height of the tip of the horizontal auger so that grains can flow from the horizontal auger into the grain bag on the machine running surface. In addition to providing a combine that can reliably prevent the lower surface and the left and right sides of the horizontal auger from colliding with the body parts other than the horizontal auger in the event of a collision, the support restricting rod used for this combine The purpose is to provide the body.

[0007]

In order to achieve the above object, a harvester according to the present invention has the following features.
A traveling device is provided below the machine stand, and a threshing / sorting unit and a grain tank are arranged side by side to form a machine body, and a grain is discharged from the grain tank to the outside of the machine. At the top of the vertical auger that rotates and rotates the grain discharging device, a grain discharging device is mounted by mounting a horizontal auger in a vertically operable state such that the tip of the auger is located below the base end. In the equipped combine, when the lateral auger is turned and tilted and reaches near the position where it collides with the front part of the fuselage, the lateral auger prevents the lateral auger from further approaching the fuselage by colliding with the lateral auger side portion. A regulatory section will be provided.

[0008] For this reason, the restricting portion is specifically configured as follows, that is, as described in the second aspect, the lateral auger tip-side upward inclination angle is equal to or less than a predetermined value. A configuration having a turning operation restricting portion that restricts the turning operation of the auger at a fixed position, and a tilting operation restricting portion that restricts a downward tilting operation in which the upward inclination angle toward the lateral auger tip is smaller than a certain size. And

The restricting portion prevents the lateral auger from colliding with an airframe other than the restricting portion. As a mode of this prevention, the turning operation of the lateral auger having a reduced tip height is performed by the turning operation restricting portion. There are two cases, that is, the case where the tip of the lateral auger is raised at a specific turning position, and the case where the tip of the lateral auger becomes lower than a certain height is regulated by the tilting operation restricting portion. On the other hand, this restricting member is configured such that the tip of the horizontal auger is placed at a predetermined specific height (for example, approximately 80c).
Even if it descends to a distance within a range of about m to 130 cm), there is no interference with the lateral auger in a range where the collision between the lateral auger and the body does not occur.

[0010] The above invention may be further embodied as follows. That is, as described in claim 3, the restricting portion is a rod member fixed to the body of the vehicle. According to this, the structure becomes a simple and lightweight regulating member.

In order to further simplify the restricting portion, the restricting portion may be formed as a single rod member fixed to the body of the vehicle, and the restricting portion may be formed by the turning member. A configuration is provided that includes a vertical portion forming an operation restricting portion and a horizontal portion forming the tilt operation restricting portion.

Further, it is preferable that the restricting portion is provided near the base end side of the lateral auger, as described in claim 5, so that the restricting portion is reduced in size.

A vertical auger that rotates and rotates a grain discharger that discharges grains from the grain tank to the outside of the machine. A horizontal auger is tilted up and down so that the tip is located below the base end. In a combine equipped with a grain discharging device mounted in a possible state, the regulating member is generally located above the point between the grain tank and the threshing sorting section. At this time, as described in claim 7, it is preferable that the regulating portion is supported on a cylindrical frame of a fry conveyor for transporting the grains from the threshing and sorting section to the grain tank. According to this, the restricting portion is less likely to interfere with other objects constituting the machine body, and is easy to handle during work, maintenance and inspection.

Further, as described in claim 8, a supporting member for supporting the middle of the length of the lateral auger in the housed state, and the regulating portion are integrally formed, and the whole is formed as one piece. It is made up of a rod member. According to this, the structure including the support mechanism for supporting the lateral auger in the housed state is simplified.

[0015] The support restricting rod used in the harvester as described above is constructed as follows. A traveling device is provided, and a threshing / sorting processing unit and a grain tank are arranged side by side to constitute a machine body, and a grain discharging device that discharges grains from the grain tank to the outside of the machine is vertically turned. It is used in a combine equipped with a grain discharging device in which a horizontal auger is mounted on an upper part of the auger such that the tip of the auger is located below the base end so that the auger can operate vertically. And one end of the rod is formed as a first vertical portion to which a receiving portion for supporting the middle of the length of the horizontal auger is fixed, and a lower end of the first vertical portion is formed. Continuous to the first side, and to the rear end of the first side To form a second vertical portion, and a second horizontal portion continuous with the second vertical portion, and a third vertical portion continuous with the second horizontal portion, wherein the second horizontal portion The part is in contact with the lateral auger-side part to regulate the downward tilting operation, and the third vertical part is in contact with the lateral auger-side part to regulate the turning operation thereof.

The support restricting means 12 is provided with a support restricting rod 23 via a fitting 22 on an upper part of a cylindrical frame 21a of a fry conveyor 21 which conveys the paddy selected in the threshing and sorting section 5 into the grain tank 7. At the same time as fixing,

The orientation portion 23e constitutes a turning operation restricting portion that restricts the turning operation of the lateral auger 11 around the vertical center line x in a state where the upward inclination angle toward the tip of the lateral auger 11 is equal to or smaller than a certain value.

The above-described restricting section 20 is generally provided so as not to hinder the handling of each part of the body and the maintenance and inspection.
It is arranged above a location between the threshing and sorting unit 5 and the grain tank 7. In the drawing, reference numeral 27 denotes the first auger which transports the grains from the threshing / sorting section 5 to the deep-frying conveyor 21, and 28 denotes the grains transported by the deep-frying conveyor 21 in the grain tank 7. Numeral 29 denotes an opening / closing port provided at the top of the kernel tank 7 for inputting vigorously with rotating blades not provided.

Next, an example of use of the combine and grain discharging device 8 and the operation of each unit will be described. During the traveling movement of the body by the traveling device 1, the cutting unit 3 cuts the planted grain culm, the threshing sorting unit 5 threshes the cut culm, and selects only fine grains from the thus obtained grain. The first auger 27 and the fry conveyor 21 operate so as to be conveyed and stored in the grain tank 7. The kernels thus stored must be carried out to a truck bed, a kernel bag n on the machine running surface m shown in FIG. 5B, or the like. In such a case, the kernel discharging device 8 is used.

When the discharge device 8 is used, the electric hydraulic cylinder device 15 is operated, and the horizontal auger 11 supported by the auger support 19 is turned into an inverted C-shape of the auger support 19 as shown in FIG. The tilting operation is performed upward about a fixed horizontal axis Y so as to escape upward from the receiving member 24. The lateral auger 11 having the upward inclination angle toward the tip of the lateral auger 11 that is equal to or larger than the fixed size θ1 (see FIG. 5B) does not interfere with the restricting portion 20 and allows the turning operation within the turning angle range θ2 shown in FIG. The paddy is discharged to a truck bed or the like at an appropriate position within the turning angle range θ2.

When the lateral auger 11 reaches the permissible limit of the turning angle range θ2, the lateral auger 11 is operated in the same manner as in the prior art by linking a detection signal from a limit switch or the like and an electric motor for rotating the vertical auger 11. Eleven further pivoting operations are automatically stopped. This turning angle range θ2 is set to about 270 degrees, for example.
The reason why the turning angle range θ2 is limited in this way is to avoid collision between the lateral auger 11 and the grain tank 7.

In the turning angle range θ2, in the angle range θ3 excluding the range in which the restricting portion 20 is present, the horizontal auger 11 is driven by the electric hydraulic cylinder device 15 so that, for example, the height of the grain discharge port 18 is reduced to the machine body. Approximately 80c from running surface m
The tilting operation is performed downward about the fixed horizontal axis Y until the minimum allowable position, which is a distance within the range of m to 130 cm. Therefore, in this angle range θ3, the operator places the grain discharge port 1 of the lateral auger 11 in the opening of the general grain bag n placed on the machine running surface m.
8 can be brought close to each other, and the grain flowing out from the grain discharge port 18 is surely dropped into the grain bag n.

Next, when the lateral auger 11 is turned in the direction of the arrow f1 while holding the lateral auger 11 at the minimum allowable position, when the lateral auger 11 reaches the specific position p1, the turning operation restricting portion of the restricting portion 20 is in the middle of its length. 25a, the horizontal auger 11 is prevented from further turning in the same direction against the driving force of the electric motor for rotating the vertical auger 9. This avoids a situation in which the side surface of the lateral auger 11 collides with the vicinity of the reaper 3 of the aircraft by mistake, or a worker on the aircraft running surface m is pinched between the lateral auger 11 and the aircraft.

In the turning angle range θ2, the regulating portion 2
In the angle range θ4 where 0 is present (see FIG. 5A), the turning operation in a state in which the lateral auger 11 is set to the tip-side upward inclination angle θ1 or more that does not interfere with the restricting portion 20 is allowed, but within this angle range θ4. When the tip of the lateral auger 11 is reduced to a specific height related to the height of the restricting portion 20, the middle of the length of the lateral auger 11 is decreased when the tip of the lateral auger 11 is decreased. In contact with
The lateral auger 11 is prevented from further tilting in the same direction against the driving force of the electric hydraulic cylinder device. Therefore, the lower surface of the lateral auger 11 may accidentally collide with the vicinity of the reaper 3 of the body. A situation where a driver or the like on the machine base 2 is sandwiched between the lateral auger 11 and the body is avoided.

In the above embodiment, when the horizontal auger 11 comes into contact with the restricting portion 20, the restricting portion 20
The turning or tilting operation of the lateral auger 11 is prevented against the driving force of an auger driving device such as an electric motor or an electric hydraulic cylinder device 15 for rotating the motor, but the invention is not limited to this. A sensor that detects contact with the regulating portion 20 is provided at a specific portion of the lateral auger 11 that comes into contact with the regulating portion 20, and the driving force of the auger driving device is lost by a detection signal of the sensor. The turning or tilting operation of the lateral auger 11 may be prevented by the disappearance.

[0037]

According to the present invention configured as described above,
The following effects can be obtained. That is, according to the first aspect of the present invention, when the height of the tip of the horizontal auger is reduced so that the kernel can flow from the horizontal auger into the grain bag on the machine running surface, the horizontal auger is used. The lower surface and the left and right sides of the auger collide with the body parts other than the sideways auger,
With a simple structure, it is possible to completely prevent a worker on the body running surface or a driver on the body from being erroneously pinched between the lateral auger and the body by a simple structure.

According to the second aspect of the present invention, the turning operation restricting portion and the tilting operation restricting portion of the restricting portion prevent a collision between the lateral auger having a lower end portion and the body. In addition, even if the tip of the lateral auger is lowered to a predetermined specific height (for example, a distance within a range of approximately 80 cm to 130 cm), the restricting unit 20 sets the lateral auger 11 in a range where the collision between the lateral auger 11 and the body does not occur. The swinging and tilting operation of the lateral auger 11 is allowed without any interference.

According to the third aspect, the restricting portion has a simple structure and is lightweight, and according to the fourth aspect, the restricting portion has a further simpler structure. According to this, the size of the regulating unit is reduced.

According to the sixth aspect, the restricting portion is less likely to interfere with other objects constituting the body, and is excellent in handleability during work, maintenance and inspection, and the like. According to this, the restricting portion is firmly supported, and it is not necessary to provide a special member for supporting the restricting portion in a conventional combine.

According to the eighth aspect, the structure including the support mechanism for supporting the lateral auger in the housed state is simplified.

According to the ninth aspect, the restricting portion can be easily attached to a conventional combine, and properly exerts its function.
