Description

TECHNICAL FIELD The present invention relates to a grain discharging device such as a combine.

Conventional technology A shooter for guiding the grains in the tank into the paddy bag is generally provided below the grain outlet of the grain tank mounted on the combine and the like. The shutter is mounted so that it can be opened and closed. Then, when taking out the grain, set the paddy bag on the hanger for hanging with the shooter immersed in the opening of the paddy bag, open the shutter and discharge the grain into the bag, and the paddy bag is full. When that happens, the shutter is closed and replaced with an empty paddy bag, and this work is repeated.

Problems to be solved by the invention For this reason, it is necessary to open and close the shutter each time, which puts a burden on the operator.

Conventionally, there is also provided a shutter and a shooter that are interlocked with each other (Japanese Utility Model Laid-Open No. 57-122245), but when this shutter is closed, the shooter interlocks with the shutter and puts it on the side of the paddy bag. The shutter rotates, but on the contrary, even if the paddy bag is rotated, the shutter does not close in conjunction with it, and the shutter has to be opened and closed manually each time, and the shutter is full when the shutter is closed. Since the paddy bag is extruded, there is a drawback that a large operation force is required.

Means for Solving the Problems Therefore, the present invention, in a grain discharging device such as a combine which droops a shooter below the grain outlet of the grain tank and can open and close the grain outlet by a shutter, An urging spring that pivotally supports the shooter with respect to the grain tank toward the take-out side of the paddy bag, and a biasing spring that elastically urges the shutter in the closing direction, and an action posture that holds the shutter in the open position. A stopper that can be switched to a non-acting position that releases the shutter open position holding action is provided, and a stopper release mechanism that releases the shutter open position holding action is connected to the shooter at the initial stage of rotation of the shutter to the rice bag removal side. The shutter's opening position holding action of the stopper is released in conjunction with the initial operation of the shooter's rotation toward the paddy bag removal side, and the shutter is closed from the open state by the elastic force of the biasing spring. The above-mentioned problems are to be solved by the above-mentioned configuration.

Action When the grain bag in the tank is filled up, and when the paddy bag is full and the paddy bag is pulled outward, the shooter is pushed by the paddy bag and rotates toward the pulling side of the paddy bag. Then, the shutter is automatically closed in conjunction with the rotation of the shooter.

Example A is a self-removing combine, in which a grain tank 2 is mounted on one rear side of the driver's seat 1, a threshing section 3 is mounted on the other side, a pretreatment section 4 is disposed in front of the fuselage, and a rear side is disposed in the rear. An after-treatment system 5 such as a cutter is provided for each. 6 is a fried grain cylinder, the discharge port a of which faces the rear inner corner of the tank 2.

The tank 2 is a funnel part having one grain outlet in the inside and outside directions.
A plurality of 2a are provided in the front-rear direction, and each funnel portion 2a is formed in a rectangular shape that is long in the inner and outer directions, so as not to reduce the tank capacity, and as shown in FIGS. 2 and 4. Depending on the size of the aircraft, an additional funnel part 2b can be connected to the front part to change the tank capacity arbitrarily and the funnel parts 2a, 2
The direction of the discharge port a can be adjusted according to the number of b.

3 (A), (B), and (C) are structural examples in which the direction of the discharge port a can be adjusted, and the popping-out vane case 6a fixed to the top of the fried cylinder 6 is shown.
The bolt hole 6c provided in the mounting plate 6b is formed in an arc shape, and the hinge-shaped mounting piece 6d pivotally connected to both sides of the discharge port a is provided with a horizontally long bolt hole 6e. Is variably configured.

By the way, below the funnel portion 2a of the tank 2, a gutter body 2'in which a fulcrum shaft 7 having a shutter operation lever 7a fixed at one end is rotatably inserted and horizontally mounted is detachably mounted via a bolt P,
The bottom plate 2'a of the gutter body 2'is formed in an arc surface centered on the fulcrum shaft 7 except for the inwardly inclined portion b, and the bottom plate 2'a is located below the fulcrum shaft 7 and The grain outlet 8 is opened. The trough body 2'has a shutter, a shooter, and a connecting mechanism M for connecting the both, which will be described later, integrally incorporated as an assembly, and is formed in a case shape having a large volume as much as possible in order to increase the tank capacity. c is a paddy bag inserted through and supported by the hanger d. Reference numeral 9 is an arcuate shutter integrated with the fulcrum shaft 7, and the shutter 9 slides along the outer circumference of the gutter 2'to open and close the grain outlet 8. Numeral 10 is a shooter hanging below the grain take-out port 8, which is a pull-out side (arrow a) of the paddy bag C centered on the fulcrum shaft 7 via plates 11 and 11 'pivotally supported on the fulcrum shaft 7. Is supported so as to be rotatable in the direction). In this shooter 10, the rear side 10a of the paddy bag c in the drawing direction is formed in a U shape by a hard member such as an iron plate or transparent synthetic resin, and the front side 10b is formed by a flexible member of transparent vinyl. It is configured in a connected manner. With this shooter configuration, even if the shooter 10 is deformed due to paddy pressure or pressure on the paddy bag c, the space portion (grain discharge passage) is always held in the shooter 10 by the U-shaped hard member. At the same time, the shooter 10 also functions as a stopper for preventing the rice bag c from coming off.

Now, the plate 11 on one side is projected above the fulcrum shaft 7, and a roller 12 is pivotally supported on the protruding portion 11a.
Reference numeral 2 is in contact with a U-shaped swing arm 14 pivotally supported by a pin 13 on a front plate 2'b of the gutter 2 '. One side of the swing arm 14 is in contact with a stopper 17 for holding a shutter open position, which will be described later.
As described above, a stopper release mechanism T that releases the shutter open position holding action of the stopper 17 in association with the shooter 10 at the initial stage of rotation of the shooter 10 is configured. Numeral 15 is a toggle spring for positioning the shooter 10, which is stretched between the plate 11 'and the rear plate 2'c of the gutter 2'.

It should be noted that when the shooter 10 is rotated upwards, the toggle spring 15 is affected by the weight of the shooter 10 and the resistance of the shooter rotating portion.
When the robot moves over the fulcrum and reaches a position slightly above the fulcrum shaft 7, the shooter 10 is held at the position shown by the phantom line in FIG. 8, and further upward movement is performed manually. ing.

The gutter 2'is located on the rear side in the direction of the paddy bag withdrawing, and the shooter 10
And a stopper 16 for restricting rotation of the shutter 9 is fixed,
A stopper 17 for holding the open position of the shutter 9 is pivotally mounted on the front side via a fulcrum pin 18. The stopper 17 is provided with an engaging groove 17a for locking the hook 7'a fixed to the shutter operating lever 7a, and a release lever 17b integrally protruding. The stopper 17 is in contact with the lower surface on one side of the swing arm 14 and is biased by a coil spring 19 in a direction to push up the swing arm 14.

Reference numeral S denotes a biasing spring that normally biases the shutter 9 in the closing direction. As the biasing spring S, a winding spring is used in the embodiment. One end of the winding spring is on the lower surface of the pin 13, The end sides elastically contact the upper surface of the shutter operating lever 7a, respectively (see FIGS. 7A and 7B).

Next, the operation procedure of the present invention will be described. First, in order to load the spare empty paddy bag c on the base end side of the hanger d,
The process is performed in the state shown by the solid line. At this time, since the shooter 10 has moved up to the position above the hanger d and is not caught by the paddy bag c, the paddy bag c can be easily loaded. Next, lower the shooter 10 to approximately the hanger height (the position shown by the phantom line) so that the shooter 10 faces the upper opening edge of the frontmost paddy bag. In this state, move the shooter 10 further down to shooter 10. 10 is a stopper when it is immersed in the upper opening of the paddy bag c.
It abuts 16 and is positioned in the upright posture shown in FIG. Next, the shutter 9 is held in the open state by moving the shutter operating lever 7a upward to engage with the stopper 17, and the work is started in this state. When the paddy bag c is full of grains, the paddy bag is pulled out (in the direction of arrow a) and the next paddy bag is set below the shooter 10. When the filled paddy bag c is pulled out, the paddy bag is pulled out. Since the c pushes the shooter 10, the shooter 10 moves upward around the fulcrum shaft 7 toward the drawer side, which causes the roller 12 to move the swinging arm 14 around the pin 13 as the center in FIG. In order to push up in the clockwise direction, the stopper 17 rotates in the clockwise direction against the winding spring 19 to release the engagement of the shutter operating lever 7a. Therefore, the shutter 9 is rotated by the biasing spring S in the direction opposite to the shooter 10 to close the grain outlet 8. The closing operation of the shutter 9 is linked to the upward movement of the shooter 10 by the elastic force of the biasing spring S before the shooter 10 is largely rotated, that is, in the initial stage of the rotating operation of the shooter 10 to the side to extract the paddy bag. Since the operation is performed immediately, it is possible to prevent the shutter 9 from being delayed in closing the rice bag c and pulling out the rice spills when the bag c is pulled out. Will not be discharged excessively.

The shutter 9 can be closed by manually operating the release lever 17b. In this case, by pulling up the release lever 17b, the engagement of the shutter operating lever 7a is released, and the shutter 9 is automatically closed by the elastic force of the biasing spring S.

By the way, when pulling out the paddy bag c, the shooter 10 does not move up to the uppermost position at once, and after the fulcrum is crossed, it temporarily stops at the position shown by the phantom line in FIG. Scattering outside the bag c is prevented.

When the paddy bag c is pulled out further outward, the shooter 10 moves further upward as shown by the solid line in FIG. 8, and the rear side surface of the shooter 10 is inclined, which facilitates the pulling out of the paddy bag c. (It is easier because the tip of the hanger d is not bent in a hook shape.) Further, since the shutter 9 and the shooter 10 are configured to rotate about the same fulcrum shaft 7, the mechanism M for connecting them is used.
In addition, since the shutter 9 slides on its outer circumference along the arcuate surface of the trough bottom plate 2'a, the grain is not bited when the shutter is opened and closed, and the operation is performed smoothly and reliably.

The present invention can be applied not only to the grain tank mounted on the combine, but also to a tank discharging device.

Effect of the Invention As described above, the present invention provides a grain discharging device such as a combine in which the shooter is hung below the grain outlet of the grain tank and the grain outlet can be opened and closed by a shutter. Is rotatably supported with respect to the grain tank toward the take-out side of the paddy bag, a biasing spring for elastically biasing the shutter in the closing direction, an action posture for holding the shutter in the open position, and a shutter opening. A stopper that can be switched to a non-acting position that releases the position holding action is provided, and a stopper release mechanism that releases the shutter open position holding action at the initial stage of rotation of the shooter toward the paddy bag extraction side is connected to the shooter. , The shutter open position holding action of the stopper is released in conjunction with the initial operation of rotating the shooter toward the paddy bag removal side,
Since the shutter is configured to operate from the open state to the closed state by the elastic force of the biasing spring, when the shooter is rotated to the paddy bag take-out side to take out the paddy bag at the time of bag replacement, the initial stage of the turn Since the shutter closes immediately and automatically by the elastic force of the urging spring, not only can the work efficiency of bag packing be improved, but also spilling of rice can be prevented when the bag is taken out. In addition, it is possible to reliably prevent the grain in the grain tank from being excessively discharged due to the delay in the operation of the shutter, and it is possible to easily replace the paddy bag.
