Description

[Detailed description of the invention] This invention relates to an agricultural binding machine that is used for binding waste straw after being shelled in a combine harvester, or for binding husks after harvesting in a binder.

A conventional agricultural binding machine has a binding passage that passes between two overhanging case parts (two case parts corresponding to both legs of the portal) located opposite each other in a gate-shaped binding case. A clutch shaft, which is intermittently driven by a binding clutch actuated by sensing the focused shell culm pressure, is installed in one of the projecting case parts, with only one end thereof extending outward, and a transmission is transmitted from the clutch shaft. A nodule drive shaft that is intermittently driven in response to the load is equipped on the other overhanging case part with only one end extending outward, and the cord is supplied to the nodule while stretching the cord to the converging culm. A drive crank for driving the string supply means is attached to one end of the above-mentioned clutch shaft.
Further, drive cranks for driving the discharge arms that push and discharge the bundled culm bundles have been constructed to be installed at one end of the above-mentioned tubercle drive shaft, respectively.

In such conventional devices, the range in which the thickness of the culm bundle can be adjusted by expanding or reducing the width of the binding passage is limited to the range in which the binding passage passes between the two overhanging case portions of the binding case as described above. For some reason, the range of change in the width of the bundling passage is limited by the bundling case, so it is relatively small.

In addition, in the conventional type, the binding passage is designed to prevent the shell culm from hitting the connecting case part (the case part corresponding to the cross beam at the top of the portal) connecting the above-mentioned two overhanging case parts and preventing the passage thereof from being obstructed. Since the culm is formed so that the culm passes only through the position where the case part is extended and avoided toward the case part side, the release arm for releasing the bundle is also connected to the above-mentioned connecting case part when viewed in the culm length direction or the longitudinal width direction of the binding case. It is located far away from. Therefore, the other end of the clutch shaft, that is, the end located on the connecting case side when viewed in the longitudinal width direction of the binding case, is also extended to the outside of the binding case, and the ejection arm drive rank is installed at the extending end. Even so, the drive crank is far from the discharge arm and the connection mechanism between the drive crank and the discharge arm is complicated.

The purpose of this invention is to avoid the restrictions imposed by the binding case and expand the adjustment range of the bundle thickness, and also to enable the clutch shaft to directly drive not only the string supply means drive crank but also the release arm drive crank. To provide a new agricultural binding machine.

Regarding the illustrated embodiment, the configuration of the agricultural binding machine according to this invention will be explained. As shown in FIG. In a waste straw processing case 2 which is supplied with waste straw after shucking, it is installed together with a waste straw cutter C, with the waste straw cutter C disposed below and the binding machine B disposed above.

Other configurations of the string supply arm 55 and other parts related thereto will be described later along with their operation.

The above-mentioned binding clutch 42 is constructed in the same manner as well-known ones and operates in the same manner, so only an outline thereof will be explained. In FIGS. 3 and 4, 74 is
The clutch actuating arm is supported by a loose fit on the packer shaft 25, and has one end that engages with a pin 75a on the actuating arm 75 on the door shaft 27 through a long hole 74a, and a regulating protrusion 74b at the other end. In addition, a pin 77 is installed in a disk 76 that is fixed to the clutch shaft 26.
A clutch arm 78 is supported by a clutch arm 78 having a pawl 78a that engages with the regulating protrusion 74b, and the arm 78 has a spring 79 that engages a portion of the clutch gear 41 in the circumferential direction. A clutch pin 78b that can be engaged with the formed engagement portion 41b
is installed. A rotary arm 80 loosely fitted and supported by the clutch shaft 25 has a roller 82 which is in close contact with a cam plate 81 fixed to the clutch shaft 26 , and the clutch actuating arm 74 and the rotary arm 80
A clutch spring 85 is arranged between them. In the shown binding clutch 42, when a set amount of husks (waste straw) is collected in the binding passage 5 and the door 38 senses the pressure, the clutch actuating arm 74 is rotated by a small amount, and the regulating protrusion 74b is moved. When the pawl 78a is removed, the clutch pin 78 on the clutch arm 78
b is engaged with the clutch gear 41 through the engagement portion 41b under the action of the spring 79, thereby causing the clutch shaft 26 to rotate. Then, as the rotation of the clutch shaft 26 progresses and the roller 82 falls into the cam groove 81a formed in the upper cam plate 81, the rotating arm 80 and the clutch actuating arm 74 rotate in the door 38 opening direction. Then, when the roller 82 is pulled out from the cam groove 81a, both arms 80 and 74 are rotated in the direction of closing the door 38, and then the pawl 78a engages with the regulating protrusion 74b, and the binding clutch 42 is disengaged. . 87 in Figure 4

The operation of the illustrated tying machine B, especially the operation of its string supply arm 55, when tying the shredded straw with the shutters 11 and 13 in the position shown by the solid line in FIG. 1 will be explained below with reference to FIGS. 5 and 8. ,
I will explain this while supplementing Wakasen's explanation of the composition.

At the start of work and after one cycle of tying operation is completed, the tying string R is guided by the first string guide 71 on the shutter 13 and the string guide 70 at the knot, as shown in FIG. 43 and the end of the cord is held in the holder 44.
The string supply arm 55 is in a standby position with the tip of the string supply actuator 64 located at the position P ₀ , and the door 38 is in a position to close the end of the binding passage 5.

As the straw is fed into the bundling passage 5 from the state shown in FIG. 5 with the help of the police cars 27A and 27B, the string R portion crossing the bundling passage 5 moves toward the door 38. As shown in FIG. 8a, the R part of the string forms a loop, and
The straw is collected in front of the shutter 13, and the string R is moved along the surface of the shutter 13, and the second string R is moved downstream of the first string guide 71.
The string R comes into contact with the string guide 72, and as described above, the string R is kept substantially parallel to the binding path 5 between the string guides 71 and 72. As shown in FIG. 8a, when a set amount of waste straw is collected in the bundling passage 5, the bundling clutch 42 is engaged by the door 38 sensing the bundle pressure.

The actuation of the binding clutch 42 causes the string supply arm 55 to move from the standby position shown in _{FIG .} The binding passage 5 is moved in the direction of the shutter 13 until it reaches the first dead center position shown in FIG. 8b. String supply operator 6
The dead center position P ₁ of No. 4 is set between the two string guides 71 and 72 on the shutter 13, at a position slightly past the guides 71 and 72, and between the string supply actuator 64 and both strings. String R between guides 71 and 72
The relative positional relationship in the direction perpendicular to the plane of the paper in FIG.
72, the string R between them relatively climbs up the slope 64a of the string supply actuator 64, and is set so that it passes over the actuator 64 and reaches behind it.

Therefore, as described above, the string supply arm 55
crosses the binding path 5 in the opposite direction, and while the string supply actuator 64 reaches from the dead center position in FIG. 8b to the position shown in FIG. 8c, the string feed actuator 64 When passing between the guides 71 and 72, the middle of the string R enters the string guide groove 64b of the actuator 64, and the string R is in a state where it can freely slide in the length direction of the string supply actuator 64. I get grabbed. Therefore, as shown in FIG. 8c, the middle part of the string R is disengaged from the second string guide 72 and is brought to the knot side by crossing the binding passage 5, and then the string supply arm 55 further rotates. While the string supply operator 64 moves toward the building 43 and the holder 44 and reaches the position shown in FIG. 8d, the string R is applied to the collected bundle. The track at the tip of the string supply actuator 64
In C ₃ (Fig. 2), the string supply actuator 64 is connected to the building 43.
The string R is supplied to the building 43 with the string R being guided in a double manner by the string guide 70 as shown in FIG. 8 d, and then as shown in FIG. 8 e. , the string R is set so that it passes through the lower surface of the hodder 44 and is fed to the holder 44 before the string supply actuator 64 reaches the other dead center position _P2 .

When the state as shown in FIG.
a and 44a are reached, and Fig. 8 e and f
As shown in FIG. 3, the bill 43 is driven to knot the string R, and the holder 44 is driven to hold the string R and cut the string R between the knot point and the holding point using the knife 44d. It will be done. The string supply arm 55 returns from the dead center position of FIG. 8e to the standby position as shown in FIG. It is removed from child 64.

Thereafter, the string supply arm 55 returns to the standby position shown in FIG. 5 and is stopped when the clutch shaft 26 stops rotating.After the knotting is completed, the door 38 is rotated by the release rotation of the release arms 46A and 46B. The bound bundle is pushed out and released while
In the illustrated case, the opening position of the door 38 is set to a position where the door 38 is sunk into the nodule cover 69 as shown by the chain line in FIG. 2, so that the bundle can be released smoothly. It's on.

The string guide groove 64b of the string supply actuator 64 is provided to be inclined as described above, and there is a height difference h at both ends of the groove 64b on the back surface of the actuator 64 as shown in FIG. 6b.
Then, as shown in Figure 8e, the holder 44
is placed within the range of the height difference h within the loop of the string R held by the string supply operator 64, and holds only the end of the string R that will be used for the next binding.
Double take of the string R by the holder 44 is reliably prevented. Furthermore, when the string R is removed from the string supply operator 64 from the state shown in FIG.
4, the position where the string R engages with the string supplying actuator 64 and the position where the string R is held with the holder 44 are sequentially given a height difference, so this is extremely easy.

As is clear from the above description of the embodiments, the agricultural binding machine of this invention has the binding cases 21 and 22 located only on one side of the binding passage 5, and the binding cases 21 and One end and the other end of the clutch shaft 26 equipped on the clutch shaft 22 extend outside the binding cases 21 and 22, and a string supply means drive crank 59 is attached to one end of the clutch shaft 26.
, and a discharge arm drive crank 50 at the other end.
Each item is equipped with the following effects.

In other words, the binding case is provided only on one side of the binding passage, and the width of the binding passage can be expanded or reduced on the opposite side of the binding case without restriction. According to this invention, the width of the binding passage is not limited by the binding case. This means that the range of adjustment of the thickness of bundles to be bound can be expanded.

In addition, since the binding case is provided only on one side of the binding passage, and there is no part of the binding case that impedes the passage of the culm passing through the binding passage, the culm can be moved along the length of the culm. The binding case can be passed across the width of the binding case and passed through the binding passage, so the release arm for pushing out the culm after binding can be projected into the binding passage from either side of the binding case length. This means that it can be rotated to act on the shell culm bundle. Therefore, the driving crank 5 of the string supplying means is attached to one end extending outside the binding case.
Even if the clutch shaft 26 equipped with the release arm 9 is extended out of the binding case at the other end and the release arm drive crank 50 is installed at the other end, the release arms 46A and 46B shown in the embodiment are One discharge arm is provided at a position close to the latter driving crank 50, such as one of the discharge arms 46A,
The ejection arm can be easily connected to the ejection arm drive crank 50. Therefore, this idea connects the clutch shaft 26 to the binding case 2 at both ends.
1 and 22, and one end is equipped with a string supply means drive crank 59.The other end of the clutch shaft 26 is equipped with a release arm drive crank 50, and the clutch shaft 26 not only allows the string supply means but also the release. The arm is also driven directly, which simplifies the structure of the drive mechanism in the agricultural binding machine.
