Description

DETAILED DESCRIPTION OF THE INVENTION In the conventional binding device, a one-turn clutch is engaged and activated by door pressure, thereby driving and binding the knot and the booklet. In other words, the size of one bundle was kept constant, but
The moisture content of extremely lodging culms, culms that are wet from rainwater or morning dew, etc. is much higher than that of dry culms, so if culms with different moisture contents are tied together to a certain size, the drying time will be reduced. This caused problems in collection and other post-processing.

Further, the configuration of the constant pressure spring that senses the door pressure, the associated link mechanism, and various mechanisms for connecting and disconnecting the one-rotation clutch is extremely complicated, resulting in heavy liquid and high cost.

The object of the present invention is to improve the above-mentioned drawbacks, by providing a weight sensing device at the bottom of the converging section, and applying the weight, This device is characterized in that the sensing devices are interlocked and the binding operation of the bipedal needles and knot portions and the raking operation of the packer are interlocked so as to be substantially synchronized.

To explain the male side of the fruit shown in the lower part of the figure, this binding machine is attached to the rear of the threshing device of a combine harvester and binds waste straw discharged from the threshing machine. Transmission case 1 provided in 5. □The packer 2 is equipped with a needle 3 on which a string is hung during tying, and a door 4 which is forced to stand up by a string, and is located above the transmission case 1 at a portion across from the convergence part. A nodal shaft 9 is provided with a nodal part in which the building 5 and the holder 6 are surrounded by a nodal guide 7, and a cam 8 for driving the bill 5 and the holder 6 is attached to the nodal shaft 9. is interlocked with the timing axis lO that drives the needle 3 by a chain case on the ear side, and when the sweeper 11 is connected to the tip 8 with a pin, the swing arm 1 is connected to -Ii.
2, it is connected to the case 13. In front of the gusset/focusing part, there is a rotating shaft 1.
A scraping body is provided, which is made up of a fixed arm 15 fixed to 4, tines 1B and 113 pivotally connected to both ends thereof, and a cam 17 that hangs down from the bearing and has spring-backed returns 1G and IEI in pressure contact. be.

The stacking plate 18 placed at the bottom of the convergence section between the front guide plate 18a and the rear guide plate 18b has a pair of rods I! 3.18, and the rods 199 and 19 are loosely fitted to the support plate 22, and are supported by winding springs 21 and 21,
A weight sensing switch 23 provided on the support 22 faces the bottom surface of the stacking board 18.

The timing shaft 10 is moved by a gear 24, 24' to a one-rotation shaft 25, and the one-rotation shaft 125 is connected to an input shaft 27 via an electromagnetic clutch 26.

In the above-described device, the raking body successively rakes the waste straw into the collecting part, and as the basket increases, the coiled spring 21.2
1 is compressed and when it reaches a predetermined age, the 1st stack 18 presses the weight sensing switch 23 as shown in FIG. 1, 28 is in contact with the protrusion 28 and is in contact with contact a in the circuit shown in FIG. When the 1-rotation shaft 25 starts, the 1-rotation switch 2 moves away from the protrusion 28 and switches to the contact point, so the 1-rotation shaft 25 continues to rotate, and when it rotates once, the 1-rotation switch 28 switches to the contact a side. , one rotation @b25 stops.

Meanwhile, packer 2. The bundled waste straw is compressed on the front side of C and A 4, and at the same time, the needle 3 hangs a string, and when the knot is knotted, the stone parr 11 removes the knot and bundles it to form a bundle. Then, when the one-turn switch 28 mentioned above switches to contact a, the bundle discharge has finished, so the stacking plate 18
The raking body is pushed up by the winding springs 21 and 21 and returns to the position of receiving the straw to be raked, and the weight sensing switch 23 is turned off.

It should be noted that the door 4 collapses outward against the spring biasing it to stand when the bundle is released to the east, but immediately returns to the upright position when the bundle is released.

Next, another embodiment of the weight sensing switch will be explained with reference to FIGS. 5 and 6. In general, a combine harvester adjusts the handling depth and then feeds the grain to the threshing machine □ for threshing processing, so the amount of grain that is discharged from the threshing machine is The position of the tip of the waste straw remains almost constant, whereas the position of the tip of the straw in the original plant varies depending on the length of the culm.

Therefore, if the weight of a long or short culm is sensed at one point in the convergence part, it is impossible to measure the weight of a long or short culm at its center of gravity.
As shown in Fig. 5, two sets of accumulation plates and heavy mortality detection switches 23' and 23'' (consisting of potential meters in this example) are arranged in the direction of the culm, and they detect and detect The amount is added to the adder 3o, and the output e1 is compared with the output e2 of the setter 31 by the comparator 32.
When the output of 0 becomes larger than the set value e2 of the setting device 31, the output is output, and the sysister 33 is turned ON, the electromagnetic clutch 26 is engaged, and the 1-rotation shaft 25 is started as in the above-mentioned embodiment. , 1 turn switch 2 days is turned on and 1
After rotation, the protrusion 28 turns it off.

In addition, although the above-mentioned embodiment explained the example of tying waste straw in a compact manner, it goes without saying that the present invention can also be applied to a reaping and tying machine.

As described above, the present invention provides a weight sensing device at the lower part of the convergence part, and connects the weight sensing device □ to the needle and the nodal part so that they operate once. This is because the tying operation and the raking operation of the packer are linked so as to be approximately synchronous with each other, so that the weight of the bundled grain camphor'i can be kept approximately constant regardless of whether the culm is wet or dry. Then, tie the wet culms with high specific gravity into small culms with low moisture content and dry for about the same amount of time.
However, it is possible to efficiently collect and process one sample at the same time.

□ Also, there is no need for a complicated door sensing mechanism or one-rotation crunch mechanism as in conventional binding machines, and the weight and cost of the machine can be significantly reduced.
