Description

[Detailed Description of the Invention] This invention relates to a grain bagging device, specifically, a grain bag having an opening at the bottom of a grain tank having a plurality of supply ports to receive grains supplied from each of the supply ports. This invention relates to a bagging device equipped with a plurality of support rods for suspending.

Generally, in a combine harvester, the grain culm cut by the reaping part is threshed by the threshing part, and the threshed grains are supplied to a grain tank provided on the side of the threshing part, and the grains are fed from the tank. It's like packing it into a bag of grains.

Therefore, the grain bagging operation is carried out by suspending both upper sides of the grain bag from support rods provided below the tank.
The opening of the bag faces the supply port of the tank, and the bottom of the bag is placed on a pedestal below the support rod.

By the way, the work of the combine harvester is often performed by one operator, for example, the steering operation of the combine and the bagging work are performed by one operator. After the grain bag supported by the support rod faces the supply port of the grain tank in order to take it out, the operator returns to the driver's seat and operates the combine harvester,
The bagging of grains is done automatically.

However, during the grain bagging operation as described above, it is not possible to effectively fill the grain bag with a predetermined amount of grain by simply charging the grain from the tank into the grain bag. Moreover, if the bottom of the grain bag is bent, it is not possible to fill the grain bag with a predetermined amount of grain.

Conventionally, as shown in Japanese Utility Model Application Publication No. 52-8086, for example, a vibrating body is provided on a pedestal that receives the bottom of a grain bag, and the vibrating body pushes up the bottom of the bag to vibrate it. A bagging device was proposed in which grains were forcibly filled into the bag.
In such a bagging device, unless the amplitude of the vibrating body is increased, the vibration of the vibrating body will not be transmitted to the upper part of the bag, and a reliable bagging effect cannot be expected. However, when increasing the amplitude of the vibrating body in order to apply the vibration to the top of the bag, there is a risk of giving a large shock to the support rod and causing damage, and moreover, the bottom of the grain bag may be bent. In such cases, it was no longer possible to cope with the situation, and it was no longer possible to bag the grain reliably and effectively.

Furthermore, in the bagging device, it is necessary to push up the bottom of the grain bag using a vibrating body, which means that it is necessary to push up the entire heavy bag containing grains, resulting in power loss. It's big.

However, in order to solve the various problems mentioned above,
The support rod that suspends the grain bag is swung vertically via a swinging device, and the grain bag is raised and lowered relative to the pedestal by the swinging of the support rod, thereby packing the grains into the bag. He first proposed and filed an application for a system that would allow the bagging process to be carried out reliably and efficiently.

By the way, in the case of a normal combine harvester, a plurality of supply ports are provided below the grain tank, a pair of support rods are provided below each of the feed ports, and bags are suspended from each of these support rods. , so that each bag is filled simultaneously from each of the supply ports,
Therefore, in such a combine harvester, when each of the support rods is oscillated, the following problems occur.

That is, when each grain bag is filled with a certain amount of grain, each of the support rods is simultaneously swung up and down via a swinging device. When using one rocking device, the overall structure can be simplified, but since a large load is applied to the rocking device by each bag filled with grain, the rocking device must be strong enough to overcome the load. It needs to be large.

However, we considered using a plurality of swinging devices to swing each of the support rods individually, but in this case, each swinging device could be made smaller; Installing each unit separately below requires a small installation space, which not only poses design problems, but also makes the overall structure extremely complex.Moreover, when multiple rocking devices are used, the number of attached parts increases. As the number increases, the production cost becomes high.

The present invention was devised based on the above considerations, and its purpose is to simplify the overall structure by using one rocking device, and to simplify the overall structure even though only one rocking device is used. To provide a bagging device which can perform bagging work reliably and efficiently by making the moving device small.

Therefore, the configuration of the present invention supports each of the support rods so as to be able to swing up and down, and also links each of these support rods to a single rocking device, while creating a phase difference in the rocking of each of the support rods. By providing the support rods and swinging the support rods up and down alternately, that is, when one of the support rods is moved upward to lift the grain bag,
On the other hand, by lowering the support rod to lower the grain bag onto the pedestal, it was possible to perform the bagging operation with a small amount of power.

The grain bagging apparatus according to the present invention will be explained below with reference to the drawings.

In the figure, 1 is a grain tank installed on the side of the threshing section D of the combine. The grains threshed in the threshing section D are fed into the tank.

In addition, there are two supply ports 1 at the bottom of the tank 1.
a, 1b, two sets of support rods 2a, 2a, 2b, 2b are provided below the supply ports 1a, 1b extending outward from the threshing section D side, and each set of support rods 2a, 2a, 2b, 2b is provided. Below the support rods 2a and 2b is a pedestal 3.
has been established.

In this way, both upper ends of grain bags 4 are suspended from each set of support rods 2a and 2b, and the openings of each bag 4 are made to face each of the supply ports 1a and 1b of the tank 1, and The bottom of each bag 4 is placed on the pedestal 3, so that grains are packed into each bag 4 from the tank 1.

In the bagging apparatus as described above, each set of support rods 2a, 2b is supported vertically swingably, and each set of support rods 2a, 2b is supported vertically.
b is linked to one swinging device 5, while providing a phase difference in the swinging of each of the assembly rods 2a, 2b.

Specifically, cylindrical rods 7, 7 extending in the orthogonal direction are respectively fixed to the proximal end sides of each set of support rods 2a, 2b, and a support member 8 is provided on the side of the threshing section D. A cylindrical body 10 extending in the same direction as the cylindrical rods 7, 7 through one shaft 9,
10 is rotatably provided, while each cylinder 10,
The cylindrical rods 7, 7 are fixed to a part of the outer periphery of the cylinder 10 by welding means, and the support rods 2a, 2b of each set are connected to the shaft rod 9 via the cylindrical rods 7, 7 and the cylindrical bodies 10, 10.
They are individually supported so that they can swing up and down around the center.

Further, each set of support rods 2a, 2b is vertically swung by one oscillating device 5, and this oscillating device 5 includes a transmission case 13 having a motor 11 and an output shaft 12 connected to the motor 11. It consists of
Rotational power is transmitted from the motor 11 to the output shaft 12 via a gear mechanism (not shown) housed in the case 13.

Then, the output shaft 12 is made to protrude outwardly from both sides of the case 13, and rotating bodies 14, 14 are eccentrically attached to the output shaft 12 at both outer ends of the output shaft 12, and both rotating bodies 14, 180 in 14
The swing links 15 and 1 are provided on the outer peripheral surfaces of the cylinder rods 7 and 7, respectively.
5 is fixed, while the links 15, 15 and the respective rotating bodies 14, 14 are connected via connection rods 16, 16, respectively, so that the respective rotating bodies 14, 14 are fixed as the output shaft 12 rotates. Due to the eccentric rotation of the rods 16, 16 and the links 15, 15,
The supporting rods 2a, 2b of each set are alternately oscillated up and down with a phase difference of 180 degrees.

In this way, each set of support rods 2a, 2b is
By alternately swinging up and down with a phase difference of 180 degrees, when one support rod 2a is moved up to lift the grain bag 4, the other support rod 2a is moved down to lift the grain bag 4.
In other words, each bag 4 is moved up and down alternately like an elevator, reducing the load on the motor 11, and even with a small amount of power, each set of support rods 2a, 2b can be moved up and down. It is the movement that takes place.

In the figure, reference numeral 6 denotes a balance spring stretched between the tips of the links 15, 15 and the support member 8.

In the illustrated embodiment, a sensor 17 for detecting grain stagnation is provided inside the tank 1 near each of the supply ports 1a and 1b, and the sensor 17 is linked to the motor 11 so that the sensor 17 In the ON operation, each set of support rods 2a, 2 is connected via the motor 11.
b is made to swing up and down.

In the figure, 18 indicates each supply port 1a, 1b of the tank 1.
This is a shutter that can be opened and closed freely.

The bagging device of the present invention is constructed as described above, and during the bagging operation of grains from the grain tank 1 into the grain bag 4, each set of support rods 2a, 2b is attached to both sides of the opening of the bag 4. This is carried out by suspending the bags 4 from each other, with the openings of each bag 4 facing the supply ports 1a and 1b of the tank 1, and by opening the shutters 18 of the supply ports 1a and 1b.

Thus, with the opening of the shutter 18,
The grains in the tank 1 are sequentially filled into each bag 4, and the grains are filled up to the vicinity of the opening of each bag 4, and the grains are flowed out from the supply ports 1a and 1b of the tank 1. When the grains are stagnated near the supply ports 1a and 1b without being stagnant, the stagnation of the grains is detected by the sensor 17, and the motor 11 is rotationally driven by the output signal from the sensor 17.
Each group support rod 2a, 2b is swung vertically for a certain period of time, and this oscillation causes each bag 4 to be raised and lowered with respect to the pedestal 3, and grains are stuffed therein to perform bagging work. It is.

Therefore, when the group support rods 2a, 2b are oscillated up and down, the rotating bodies 14, 14 are supported by the output shaft 12 of the motor 11 with a phase difference of 180 degrees. The rods 2a and 2b are alternately swung up and down, that is, each set of support rods 2
Each bag 4 suspended by a and 2b is raised and lowered alternately like an elevator. Therefore, the torque required for the motor 11 to lift each bag 4 is halved, and the motor 11 The power of the engine is reduced.

In addition, in the embodiment described above, the phase difference is set to 180
degree, but it is not limited to only 180 degrees.
Furthermore, although two sets of the support rods 2a and 2b are used, two or more sets may be used.

As explained above, in the bagging device of the present invention, a plurality of support rods are supported so as to be able to swing up and down, and each of the support rods is linked to one rocking device.
Since a phase difference is provided in the swinging of each of the support rods, each support rod can be alternately swung up and down, that is, each bag suspended by each support rod can be raised and lowered alternately like an elevator. The load caused by each bag on the swinging device can be reduced, and bagging work can be carried out reliably and efficiently even with a small amount of power.Furthermore, each support rod can be swung by a single swinging device. As a result, the entire device can be simplified, the number of parts can be reduced, and the device can be provided at a low cost.
