Description

[Detailed description of the invention] The present invention includes a bagging hopper provided on the side of the machine body, and a support rod that supports the paddy bag in a position to receive grains discharged from the grain outlet of the bagging hopper. This invention relates to a bagging section of a mobile threshing machine equipped with.

Conventionally, in general, the bagging section of the mobile thresher has a pair of support rods in a mutually parallel posture below a bagging hopper provided on the side of the machine body, and a grain discharge port at the bottom of the hopper is positioned between them. The rice grain bag is placed in a supporting structure such as a locking hole provided at the left and right corners of the grain receiving port at the upper end of the paddy bag. The structure is such that the rice bag is supported in a position to receive grains from the bagging hopper while the support rods are inserted and suspended. Conventionally, there have been two types of support rods: one in which the support rods remain fixed, and the other in which the support rods are slid in the longitudinal direction and can be changed in position, such as the one disclosed in Japanese Utility Model Application No. 53-71546. was known.

However, in the case where the support rod remains fixed, the tip of the support rod is placed outside the grain discharge port of the hopper to make it easier to manually suspend or remove the rice bag from the support rod. If the support rod is configured to extend in the opposite direction, the support rod will easily come into contact with other objects when the vehicle is running, etc.
There is a high risk of damage, and there is also a drawback that it is easy for workers working near the bagging section to come into contact with it, reducing safety. Although the above structure improves the safety, etc., it has the drawback that the grain discharge port gets in the way of suspending and removing the paddy bag, which takes time and effort.

In addition, the above-mentioned Utility Model Application Publication No. 53-71546 is
This is a device that bags the grains discharged from multiple hoppers arranged in parallel in the longitudinal direction of the support rod, and is in a position that allows the grains discharged from the hopper located furthest outside the machine body to be packed into bags. The supporting rod is extended and contracted in its longitudinal direction to switch between the position of bagging only the grains discharged from the hopper located inwardly of the machine, and the switching operation is performed using the support rod that can be expanded and contracted. This is a separate operation from the operation of the operating tool that discharges grains from the hopper. For example, when filling grains into a paddy bag, the rice bag is The operation of changing the posture of the support rod to a posture that can accept grains from the hopper well and the operation of starting to discharge grains from the hopper must be performed separately, and the starting, stopping, and switching operations are complicated. It had the following drawback.

In addition, conventionally, in order to prevent the discharged grains from leaking out of the paddy bag, the grain discharge port of the hopper was
The grains of the paddy bag supported by the support rod are positioned so that they are placed far into the bag from the grain receiving opening of the paddy bag, and the grain discharge port does not get in the way when the paddy bag is attached to and removed from the support rod. It is known that the grain discharge port can be repositioned to a position near the receiving port, but conventionally, the position of the grain discharge port has been changed using a manually operated lever connected to the grain discharge port. Because of the switching operation, when attaching and detaching the paddy bag to and from the support rod, as mentioned above, along with the operation of changing the posture of the support rod and the operation of starting and stopping grain discharge,
It has the disadvantage that it is complicated because it requires separate switching operations.

The present invention was developed in view of the above-mentioned circumstances, and it avoids damage to the support rod from contact with other objects when the aircraft is running, improves safety for workers, and prevents rice cracking against the support rod. This makes it easy to attach and detach the bag, and to change the posture of the support rod.
To provide a bagging part of a threshing machine that can be easily operated in conjunction with starting and stopping operations for discharging grains from a hopper and changing the position of a grain discharge port with respect to a paddy bag.

In order to achieve the above object, the bagging section of the threshing machine according to the present invention supports a paddy bag whose tip end is near the grain discharge port of the bagging hopper and is positioned to receive grains. It is configured to be able to freely switch between a first posture and a second posture in which the tip of the support rod extends further outward from the fuselage.
The grain supplying position is such that the grain discharge port is inserted into the paddy bag supported by the support rod, and the grain supplying position is such that the lower end side is inserted into the bag from the grain receiving port of the paddy bag, and the grains of the paddy bag are The structure is configured such that the posture can be changed to a standby posture separated upward from the receiving port, and further, the support rod, the grain discharge port, and the opening/closing operation tool are opened and closed when the opening/closing operation tool is opened. The support rod is switched to the first position, the grain discharge port is switched to the grain supply position, and the support rod is changed to the second position as the opening/closing operation tool is closed.
Further, the grain discharge port is interlocked so as to be switched to the standby position.

Next, the effects of the present invention based on the above characteristic configuration will be explained below.

According to the above configuration, in the second posture of the support rod in which the tip of the support rod extends outward from the grain discharge port of the bagging hopper, the tip of the support rod is positioned outward from the grain discharge port. This means that operations related to paddy bag removal, such as closing the opening of a full bag removed from the grain discharge port, can be performed easily while the bag remains attached to the tip of the support rod. Moreover, when attaching an empty bag, it is easy to attach the empty bag to the support rod regardless of the position of the grain discharge port.

In addition, in the case of the support rod in the first position where the tip of the support rod is near the grain discharge port and supports the paddy bag at the position where the grain is received, other objects may be generated due to the excessive protrusion of the support rod toward the outside of the machine. The attached paddy bag is positioned near the grain discharge port so that the attached paddy bag can be well received by the grain discharged from the bagging hopper while avoiding damage caused by contact with the support rod. It will be done.

Furthermore, the support rod, the grain discharge port, and the opening/closing operation tool thereof are arranged so that, as the opening/closing operation tool is opened, the support rod is in the first position, and the grain discharge port is connected to the grains. Since the support rod is switched to the supply position and the opening/closing operation tool is closed, the support rod is switched to the second position and the grain discharge port is switched to the standby position. After the bag is suspended and installed, simply operate the grain discharge port with the opening/closing operation tool, and in conjunction with this operation, the paddy bag suspended from the support rod will be positioned near the bottom of the grain discharge port. The posture is switched to one posture, and the grain discharge port is switched to the grain supplying posture in which it is largely inserted into the paddy bag. On the other hand, after the grain filling is completed, the grain discharge port is simply closed using the opening/closing operation tool, and in conjunction with this operation, the support rod is also switched to the second position,
Then, the grain discharge port is in a standby position where it is separated upward from the grain receiving port of the paddy bag, so that the grain discharge port does not get in the way when the paddy bag is attached to and removed from the support rod, and the grain discharge port is removed from the support rod in the second position. The paddy bag has become easier to put on and take off.

Therefore, it is easy to attach and detach the paddy bag to and from the support rod, and it is possible to avoid the support rod from coming into contact with other objects or damaging it during running, etc., improving safety for workers, and making it easier to operate the opening/closing operation tool. Easy to operate,
The posture of the support rod can be easily changed to the first position where the paddy bag can be easily attached and removed, and the second position where the grains can be received in the paddy bag, and the posture of the grain discharge port relative to the paddy bag supported by the support rod can be changed. This has resulted in advantages such as being able to switch easily.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in FIG. 1, an automatic threshing device 3 and a boarding operation section 4 are installed on a machine frame 2 equipped with a pair of left and right crawler traveling devices 1. The front reaping section 6 is transported and supplied to the threshing device 3 while being changed to a sideways posture.

A grain bagging hopper 10 receives threshed grains and is provided with a shutter 8 as an opening/closing operation tool and a grain discharge port 9 at two locations appropriately spaced apart from each other in the front-rear direction at the bottom of the hopper 10. are installed and a combine harvester is configured.

The grain bagging structure from the bagging hopper 10 will be described in further detail. As shown in FIG. 2 and FIG.
0a, and an outlet portion 10b which is fitted onto the lower end side of the hopper discharge guide path portion 10a so as to be slidable up and down.

Below the hopper 10 and around the grain discharge port 9, in order to support the paddy bags A in a grain-receiving posture, they are arranged toward the outside of the machine in a manner that is distributed in the longitudinal direction of the machine with respect to the grain discharge port 9. and a rod 11 connecting the inner ends of the fuselage
A pair of rice bag support rods 11 are provided which are integrally connected by a. This paddy bag support rod 11 is connected to a pair of support brackets 12 connected to the machine body at an end portion on the inner side of the machine body so as to be able to slide integrally in the longitudinal direction of the support rods 11. The shutter 8 and both support rods 11, which are opened and closed by sliding operation on the discharge guide path portion 10a, are connected to the projecting portion of the shutter 8 toward the inside of the body and the support rod connecting rod 11a, and are opposed to each other. Due to the meshing action between the pair of rack gears 15 and the pinion gear 14, which is freely rotatably supported on the fuselage side and engages with them, both support rods 11 slide to a state where they protrude outward from the fuselage when the shutter 8 is closed. When the position is changed and the shutter 8 is opened, both support rods 11 are retracted to the inside of the machine. With the closing operation of step 8, the support rod 11 is automatically projected to the outside of the machine body, and the length of the guide of the paddy bag A at the outside part of the machine body is increased, so that the worker can prevent the hopper 10 body from becoming an obstacle. The structure is such that the paddy bag A can be attached and detached without any trouble, and the shutter 8
Traveling in the open state During reaping and harvesting work, or during work other than attaching and removing paddy bags, such as when traveling on the road, by keeping the shutter 8 in the open state, the support rod 11 is retracted to the inside of the machine. ,
It is constructed to prevent damage caused by contact between the support rod 11 and other objects as the machine moves, and to improve safety for workers working near the bagging section.

In addition, the outlet tube portion 10b of the grain discharge port 9 is operatively connected to the shutter 8 via a link mechanism 13 so that the operation of attaching and removing the paddy bag can be performed more easily by automatically raising the outlet tube portion 10b of the grain discharge port 9. Then, when the shutter 8 is operated to close, the outlet cylinder portion 10b rises to a state where it is separated from the opening as a grain receiving port of the paddy bag A in the grain receiving position, and when the shutter 8 is opened, the outlet cylinder portion 10b is lifted. is configured to be lowered into a state where it is inserted into the opening of the paddy bag A in the grain-receiving position.

Furthermore, as shown in FIGS. 2 and 4, the grains spilled onto the bagging section deck 16 that supports the paddy bag A with the grains loaded are collected, and straw waste, garbage, etc. are collected and cleaned. A suction device 18 with a suction hose 17 is attached to the upper end of the hopper 10, and an opening 19 is formed on the lower surface of the connection portion of the suction device 18 to the hose 17, and the opening 19 and the inside of the hopper 10 are connected to each other. Connect and connect the hose 17
The structure is such that the grains, straw waste, etc. that have been sucked and conveyed inside the hopper 10 are collected and dropped from the opening 19 into the hopper 10 by their own weight.

In addition, as shown in FIG. 5, the support rod 11 is configured such that as the support rod 11 slides toward the outside of the machine when a full paddy bag A is taken out, it engages with the locking hole of the paddy bag A. A locking protrusion 20 that tilts and moves the upper side of the rice bag A toward the outside of the machine body by a locking action is placed on the support rod 11 in a locking action state in which the locking projection 20 protrudes upward from the upper surface of the support rod 11.
It is installed so that it can be freely displaced between the non-latching action state and the non-latching action state in which it has been retired, and is biased by a spring or the like toward the locking action state side, so that the full paddy bag A can be taken out even more easily. At the same time, the inner working surface of the locking protrusion 20 is connected to the support rod 11.
An empty paddy bag formed on a slope connected to the upper surface and suspended and supported at the inner end of the support rod 11
When changing the sliding position of A′ to the grain receiving position,
It may be configured such that the locking protrusion 20 is retracted by the abutting action between the empty rice bag A' locking hole and the inclined surface of the locking protrusion 20.
