Description

[Detailed description of the invention] The present invention relates to a rice receiving rod for a combine that is particularly equipped with a temporary storage tank in the rice receiving device of a combine, and that allows a normal dumping port and an auxiliary dumping port to be placed together below the temporary storage tank. .

The temporary storage tank is provided so that the operator can perform the harvesting work using the combine harvester alone, without the need for an auxiliary worker.

Traditionally, the grain was fried on a grain frying conveyor and put directly into paddy bags from the dumping port, but the grain is stored in a temporary storage tank equipped with a shutter device, and after several stages of reaping work are completed, it is dumped into rice fields along ridges or on farm roads. After stopping the machine at the edge of a nearby field, the operator operates the paddy bag, receives the paddy in the temporary storage tank into the paddy bag, and unloads the full paddy bag onto the farm road. .

The present invention aims to carry out the operation of filling paddy bags from the temporary storage tank in as short a time as possible. Reducing the time required to take out the paddy from the temporary storage tank into bags will shorten the working time, so the outlet for paddy from the temporary storage tank is provided on the side of the tank in addition to the normal outlet from the hopper at the bottom of the tank. This makes it possible to take out paddy from the auxiliary spout.

In the present invention, when using this auxiliary dumping port, it protrudes to the side more than the conventional regular dumping port, so the length of the paddy receiving rod of the paddy bag placed at the bottom of the dumping port must be adjusted accordingly. Conventionally, the paddy receiving rod was constructed to be long enough to allow the use of an auxiliary outlet, or the paddy receiving rod was constructed to be extendable and retractable.

However, the operation of extending and retracting the paddy receiving rod 10 requires removing and tightening the lock nut, which is a troublesome operation.

The present invention makes it easy to put in and take out the paddy receiving rod 10,
The structure is such that the length of the paddy receiving rod 10 can be changed with a single touch.

The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

FIG. 1 is an overall perspective view of the combine, and FIG. 2 is an overall plan view.

The machine body is placed on a crawler-type traveling device 14, and a grass dividing board 1 is protruded from the tip of the machine body. The root part of the grain culm is separated by a weeding plate 1 and guided to a pulling device 2. After being raised by the raising device 2, the tip portion is transferred to the upper conveying device and placed on the entrance iron plate 13 of the threshing device 6. After the stock head is harvested by the reaping device, it is transferred from the lower conveyance device to the vertical conveyance device 4, and then to the feed chain 5 of the threshing device 6. While being held in the feed chain 5, the grain passes through the threshing device 6 and is threshed. The grains are sorted after being threshed by a threshing device 6, and fine grains are fried by a grain frying conveyor 7 and temporarily stored in a storage tank 8. Temporary storage tank 8
A hopper is provided below the hopper, and the tip of the hopper is usually provided with a spout 18.
is permanently installed. On the other hand, an auxiliary spout 9 is attached to the side surface of the temporary storage tank 8 and configured to be removable. Since the auxiliary spout 9 does not have a hopper part, when the temporary storage tank 8 becomes full, only the upper part of the pile of paddy can be taken out from the auxiliary spout 9, and when trying to take out even the last grain. Normally, the spout is 18.
must be used.

However, if there are more outlets, the efficiency of discharging paddy from the temporary storage tank will increase.

The present invention is configured so that the paddy bag 16 can be hooked under both the normal throw port 18 and the auxiliary throw port 9.

Fig. 3 is a front view of the paddy receiving device of the present invention, Fig. 4 is a front view with the paddy receiving rod suspended, Fig. 5 is a side view with the paddy receiving rod 10 suspended, and Fig. 6 is a front view of the paddy receiving device of the present invention. A plan view of the paddy receiving rod 10, FIG. 7 is also a front view.

The rice receiving rod shown in FIGS. 5 and 6 shows the shape of the rice receiving rod when three normal throwing ports 18 are provided, and is configured so that three auxiliary throwing ports can also be provided.
A horizontal rod 10b is provided at the base of the rice-receiving rod 10, and three sets of rice-receiving rods are grouped together, and a locking rod 10a is fixedly arranged parallel to the horizontal rod 10b. Then, the horizontal rod 10b and the locking rod 10a are placed in a temporary storage tank 8.
It is fitted into a support groove A provided at the lower part of the support stand 20. The horizontal rod 10b serves as a fulcrum when the paddy receiving rod 10 is lowered downward due to the weight of the paddy bag 16, and the locking rod 1
0a serves as a locking end when the end portion attempts to rise around the fulcrum. Normally, when only the spout 18 is used, the horizontal rod 10b part is connected to the lower contact part 20b.
The locking rod 10a is placed against the upper contact portion 20a to fix the vertical and horizontal movements of the paddy receiving rod. In addition, if the auxiliary spout 9 is also used, the horizontal rod 10b
is placed on the lower contact portion 20d, and the locking rod 10a is placed on the upper contact portion 20c. This lower contact portion 20b, 2
The vertical and horizontal movements of the paddy receiving rod are fixed by the upper contact portions 20a and 20c.

Furthermore, when no reaping work is to be done, it is also possible to fit the locking rod 10a into the support groove A so that the paddy receiving rod hangs down, engages with the stopper 25, and is in the stored state 10''.

As described above, the present invention provides a horizontal rod 10b for holding together a plurality of rice receiving rods 10 at the base of the rice receiving rod 10, and locks the horizontal rod 10b in parallel on the side opposite to the rice receiving rod 10. A rod 10a is fixedly installed, and the horizontal rod 10b and the locking rod 10a are fitted into a support groove A provided at the lower part of the temporary storage tank 8. Contact parts 20b, 20d and upper contact parts 20a, 20c engaged with the locking rod 10a are provided, and in the storage position where the tip of the paddy receiving rod 10 normally protrudes below the throwing port 18, the horizontal rod 10b is the lower contact part 20b
When the locking rod 10a engages with the upper contact portion 20a and the tip of the paddy receiving rod 10 is in the downwardly projecting position of the removable auxiliary throwing port 9, the horizontal rod 10b engages with the lower contact portion 20d.
In addition, since the locking rod 10a is configured to engage with the upper contact portion 20c, the following effects are achieved.

First, the working position of the paddy catch rod 10 is made variable according to the usage position of the normal dumping port 18 and the usage position of the auxiliary dumping port 9, so it can remain long and protruding like a conventional paddy catch rod. It does not get in the way because there is no problem, and it no longer becomes difficult to operate due to being too long when driving on the road or loading paddy.

Second, in the conventional technique described in Japanese Utility Model Application Publication No. 53-71546, when the paddy receiving rod 10 is extended and used at the position of the auxiliary dumping port 9, the paddy receiving rod 10
It was necessary to extend and retract each of the paddy rods separately, and it was necessary to loosen and tighten the lock bolt of each paddy holding rod both when extending and storing.

On the other hand, in the present invention, since the plurality of rice receiving rods 10 are grouped together in the horizontal rod 10b, it is possible to switch between two positions at the same time with a single touch.

Thirdly, the horizontal rod 10b and the locking rod 1 of the rice receiving rod 10
Since the part 0a is configured to be engaged and fixed at two positions in the support groove A, there is no need for a lock nut to fix the paddy receiving rod 10, and the paddy receiving rod 10 can be moved by simply tilting it up and down. After moving, there will be 16 paddy bags.
Due to the weight, the rice receiving rod 10 can be fixed in a non-vibrating state.
