Description

[Detailed Description of the Invention] The present invention relates to a straw binding device that is installed at the rear of the threshing device of a binder or a combine harvester to bind and release the straw after threshing.

As for conventional binding devices, cutting and binding devices commonly referred to as binders have been widely used.

The binder uses a lifting device to raise the standing rice and wheat, harvests the plant base with a reaping device, and binds the culms at the plant base.
It is a device that discharges grain into the field, and it differs from a combine single-bundle device in that the culm in the binder is unthreshed grain, whereas the culm in the binder is the unthreshed grain, whereas the binder in the binder binds the grain after it has been threshed. This is a waste of time.

Another difference in the binding condition is that with a binder, the culm is standing up and the string is tied in a horizontal direction, whereas with a combine harvester's straw tying device, the straw is laid down. Since it flows around, the connecting line is also vertical.

From this point of view, the straw tying device of a combine harvester is sent with the binder tying device upright, which requires a slightly different configuration from conventional tying devices due to the hanging and knotting conditions of the string. .

In other words, when the tying device is placed on a flat surface as in the past, the string drop prevention spring has enough force to prevent the string from falling to the extent that the string can be kept in a stationary state. A force is generated that moves the culm downward due to vertical force,
The string falling phenomenon gradually began to occur as a result of vibration.

In order to solve this problem, the present invention is designed to easily improve the effect of the string drop prevention spring on preventing the string from falling off.

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 an embodiment with reference to the attached drawings.

Figure 1 is an overall survey view of the combine harvester.

The combine is mainly composed of a traveling device 15, on which a lifting device 14, a lower conveying device 18, an upper conveying device 19, a vertical conveying device 20, a threshing device 1T, a straw binding device 1, etc. are mounted. It is placed.

The tip of the culm that is being erected in the field is pulled up by a pulling device 14, and the base of the stock is harvested by a reaping device.

Next, the stock head portion is conveyed to the vertical conveyance device 20 by the lower conveyance device 18, and the tip portion is conveyed to the threshing device 1T by the upper conveyance device 19.
will be transferred onto the entrance iron plate.

The length of the culm is adjusted while the bridge is being transferred from the vertical conveyance device 20 to the feed chain 16.

Threshing device 1 is connected to the stock head in the feed chain 16.
7, the straw is shed while moving through the straw removal chain 21.
The straw is transported to the waste straw binding device 1.

. A string holding device 13 is provided on the straw binding device 1.

The configuration of the binding device 1 is shown in FIG. 2, a side view of the binding device.

At a convergence amount of 2, the receiving rod 3 collects the waste straw, and when a certain amount of convergence is reached, the receiving rod 3 operates and the needle 4 rotates to wrap the string around the waste straw, forming a knot. The needle 4 enters from one end of the guide groove 6 of the cover 5, passes through the rear side of the knot building 7, reaches the string holder 8, completes knotting by the rotation of the knot building 7, and then is released by the release rod 9. It releases the binding rod.

Figure 3 is an enlarged view of a part of the nodal hippo.

FIG. 4 is an enlarged view of the tip of the fall prevention spring.

A rigid string guide protrusion 10 is protruded near the knot of the knot building I of the needle 4 guide groove 6 of the knot cover 5, and a fall prevention spring 11 is installed near the string guide protrusion 10 in the guide groove 6.
The tip of the fall prevention spring 11 is bent inward after passing through the protrusion 5a on the upper edge of the guide groove, and when a tension above a certain level is applied to the string, the string will cross the protrusion. 5
a and the fall prevention spring.

FIG. 4 shows the above-mentioned structure as viewed from the arrow A in FIG. 3, and FIG. 4 is a perspective view showing a conventional drop-off prevention spring.

Next, see Figures 6 to 15 regarding the nodal action! To explain this, in FIG. 6, the string 12 is attached to the binding straw and the needle 4 has reached the string holder 8.
Both sides of the cord guide protrusion 10 are stopped on the circumferential side of the string guide protrusion 10, and in the figure No. 2, the nodule building is in a state where the housing is not rotating.
When the knot 7 rotates, 511, the knot building 7 on both sides of the string 120
It is in a state where it can be wrapped around the 0 base.

In FIG. 8, the knot building 7 rotates, and as shown in FIG. 9, both sides of the string 120 are wrapped around its base, and the string 12, which is locked to the string guide protrusion 10, moves upward in sequence. It is being done.

In FIG. 10, the knot building 7 has rotated approximately three-quarters, has come off the side of the string guide protrusion 10, and is locked by the fall prevention spring 11, and as shown in FIG. It is in the position where you should open it and hold the end of the string 12 in your mouth.

In Figure 12, both sides of the string 120 remain unchanged, and the spring 11 to prevent continuous fall
In the state in which the knot building 7i/f: is locked, the knot building 7i/f: rotates once in the approximately original position of the housing, and the buildings above and below are closed and both ends of the string 120 are held in their mouths, as shown in FIG. I succeeded in twisting the string so that it almost knotted.

In FIG. 14, the knot has started to move to be released from the main body, and both sides of the string 120 are forcibly released from the locking state of the falling-prevention spring due to the movement of the knot, and as shown in FIG. Both sides of the string 12 wrapped around 7 are removed, and only the gripping portions of the string 12 are held by the upper and lower buildings of the knotted building γ, almost completing the knotting.

The subsequent operation is not shown, but the nodule is placed on the release side by 7
As the layer moves, the end of the string 12 held by the knot building 7 comes off and the knot is completed.

Unlike the continuation prevention spring of the conventional binder, the continuation prevention spring of this invention is bent upward when it is placed in the combine harvester toward the inside of the knot cover as shown in Figure 2, and the straw being tied is bent upward due to the weight. This prevents the string from moving downwards and trying to come loose.

The fall prevention spring 11 of the present invention, which is housed, is fixed by a sems bolt 26 for attaching to the side surface of the knot cover 5, protrudes from a hole in the lower part of the knot cover, and extends at a protrusion R5a.

With this configuration, we were able to prevent the culm and straw debris from becoming stagnant, which was caused by attaching the fall prevention spring to the front of the knot cover, thereby preventing stagnation of the culm flow. It is.

After passing through the protrusion 5a on the periphery of the guide groove on the tip side of the spring, the fall prevention spring 11 is inserted into the guide groove 6 when viewed from the front of the knot cover 5.
The stratum corneum a0 is bent along the direction, and b0 is further bent inward in the direction approaching the surface of the tuberosity cover 5, so that the protruding edge 5a and the tip of the spring 11 for preventing the continuation of the tubercle are bent by the force of the string along the broken line in FIG. 3. Even when the housing is pulled in this state, the protruding edge 5a comes into closer contact with the portion parallel to the guide groove, increasing the prevention resistance.

In the detailed explanation, we mainly explained the waste straw binding device of a combine harvester with a binding device installed upright, but when cutting crops such as soybean binder where the culm tends to spread at the top, falling strings can be a problem. It is also effective in conventional binding devices.

As described above, the present invention is provided in the vicinity of the nodule by the nodule building T by the guide groove 6 for passing the needle 4 of the nodule cover 5.
A rigid string guide protrusion 10 is provided protruding from the periphery of the guide groove on the side remote from the knot building, and passes through the periphery of the guide groove on the same side near the discharge side of the string guide protrusion 10 to prevent continuous falling. The spring 11 is provided so as to cross the guide groove 6, and after passing through the protruding edge 5a provided at the periphery of the guide groove on the opposite side, the tip portion of the spring is aligned in the direction of the guide groove 6 as seen from the front of the tuberosity cover 5. Angle a0
Then, the same part is bent b0 inward in the direction approaching the surface of the knot cover 5, so that the protruding edge 5a and the bent end of the falling-off prevention spring 11 are in a latching state, as follows. It has a great effect.

In other words, both sides of the string are completely locked by springs to prevent falling, and the string is always in a stationary state regardless of the bundled state, so that the knotting action of the knotted bill is performed reliably.

In addition, the weight of the bundle being bundled may generate a force that pulls the string downward, causing the string to gradually fall due to vibration, but in this invention, a spring to prevent the string from continuing to fall may occur. , and the tip of the spring is configured to hang over the protruding edge 5a of the guide groove 5, so even if the string is pulled downward to the bundle, it will not easily come off from the spring, and the release rod will prevent it from coming off. It only comes off when it is released and pulled backwards with a strong force.

In addition, since the tip of the fall prevention spring is bent at an angle a0b0 in two directions, the tip of the spring and the protrusion are not only in a latched state due to the angle b0, but also the string becomes large as shown in Figure 3. When it is pulled and the fall prevention spring rotates to the position indicated by the broken line, since it is bent at an angle a0, it makes contact over a wide range at the parallel edge of the ridge 5a with the guide groove, increasing the frictional force. It maintains balance with the pulling force of the string.

In other words, when the bundle is pulled downward during tying, a certain deterrent force is generated to prevent the string from coming off, and conversely, when the bundle is pulled backwards by the release rod, a pulling force is generated backwards. The string slides between the tip of the spring and the prong, and the string can easily come off.

This action makes it possible to reliably prevent continuous drop-off.
