TECHNICAL FIELD OF THE INVENTION
The present invention relates to a powder-spraying machine, and more particularly, to a powder-spraying machine provided with a joint portion in the middle of a spray pipe so as to be bent forward.
[0002]
[Prior art]
This type of conventional powder-spraying machine is equipped with a scatter pipe attached to the rear of the body such as a tractor or a riding control machine. From the ground to the field.
[0003]
In the middle of the left and right scatter pipes, a joint is provided at substantially the entire width position of the fuselage, and a push-pull type actuator is connected to this joint, and the scatter pipe is moved forward along the fuselage by the operation of the push-pull type actuator. It is bendable.
[0004]
Further, a supporting wire is connected in the middle of the left and right spray tubes and locked to the upper portion of the support frame, and the wires prevent the spray tubes from hanging down.
[0005]
[Problems to be solved by the invention]
In the conventional powder / granule sprayer, the spray tube is bent from the middle by the operation of the push-pull type actuator so that the spray tube can be stored from the middle, but the spray tube exists in a substantially horizontal state on the side of the machine body. It is necessary to straddle this spray pipe when getting on and off. Further, since the wire supporting the spray tube is stretched obliquely, the wire may be caught by the operator when the operator gets on and off the vehicle, which is dangerous.
[0006]
Therefore, when the scatter tube is bent to the side of the fuselage and stored, there arises a technical problem to be solved in order to make it easy for the operator to get on and off and to avoid the danger of contact with the wire. It is an object of the present invention to solve this problem.
[0007]
[Means for Solving the Problems]
The present invention has been proposed in order to achieve the above object, and a scatter pipe is attached to the rear part of the fuselage in the left-right direction, a joint is provided in the middle of the scatter pipe, and a push-pull type actuator is provided in this joint. A push-pull type actuator, wherein the spray tube is bent forward along the fuselage by operating the push-pull type actuator. Means for locking the proximal end of the mold actuator to the elongated hole with a pin, and locking the proximal end of the push-pull actuator at one end of the elongated hole farthest from the joint; It is another object of the present invention to provide a powder-spraying machine provided with means for releasing the lock and moving the base end of the push-pull type actuator to the other end of the elongated hole.
[0008]
Here, if the push-pull type actuator is extended, the scatter tube rotates in a direction away from the fuselage around the joint portion, and the push-pull type actuator is moved to a full stroke when it is expanded in the left-right direction. The base end moves to one end of the longest hole from the joint.
[0009]
In this state, the base end of the push-pull type actuator is locked, so that the base end does not move in the elongated hole, and the scatter tube is prevented from swinging.
Further, when the push-pull type actuator is contracted, the scatter tube rotates around the joint in the direction approaching the machine body, and is bent forward and stored along the machine body. When the operator gets on and off in this state, the lock of the proximal end of the push-pull type actuator is released, and the proximal end is manually moved to the other end of the long hole, so that the distal end of the scatter tube is moved. The gap is generated by being pressed in a direction away from the machine body, so that the operator can easily get on and off.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION

An auxiliary blower tube 21 is connected to the fan 18, and the other end of the auxiliary blower tube 21 is connected to a lower portion of the roll 14. Most of the wind generated by the fan 18 is sent from the blower pipe 20 to the center of the spray pipe 17, and the remaining wind is sent to the auxiliary blower pipe 21.
[0012]
The spray pipe 17 protrudes left and right from the entire width of the body 12, and joint portions 22, 22 are provided outside the support frame 16 and at positions corresponding to substantially the entire width of the body 12. The joint part 22 has a bellows-shaped flexible tube 23, first arms 24, 24 that support the tube 23 and are rotatable in the horizontal direction, and are rotatable in the vertical direction. The second arm 25 includes the second arm 25.
[0013]
As shown in FIG. 3, a first arm 24 provided above and below the flexible tube 23 is composed of a base end 24a and a tip end 24b, and is rotatable in a horizontal direction by a pin 26. It is connected to. The distal end portion 24b is fixed to an annular body 27. The annular body 27 surrounds the periphery of the tubular body 23 and is connected to the second arm 25.
[0014]
As shown in FIGS. 3 and 4, a plate 29 is pivotally mounted on the rear portion of the body 12 using a pin 28 as a fulcrum, and a long hole 30 is formed in the plate 29. Then, the proximal end pin 32 of the push-pull type actuator 31 is inserted into the elongated hole 30 and connected so that the proximal end pin 32 can move along the elongated hole 30. A shaft 33 is fixed to the pin 28 in a horizontal direction. A slider 34 is slidably fitted to the shaft 33, and a boss 35 is fixedly mounted on the upper portion of the slider 34. A lever 36 is provided in parallel with 33.
[0015]
Here, a stopper 37 is fixed to the other end of the shaft 33, and a compression coil spring 38 is interposed between the slider 34 and the stopper 37 to press the slider 34 in the direction of the pin 28. Further, a fork-shaped arm 39 is fixedly mounted on the side of the shaft 33, and the lower end of the base end pin 32 is inserted into the arm 39.
[0016]
Further, a notch 40 is provided at a corner of the plate 29 near one end of the elongated hole 30, and the boss 35 of the slider 34 pressed by the compression coil spring 38 is engaged with the notch 40. . Accordingly, the rotation of the shaft 33 is stopped by the engagement between the boss 35 and the notch portion 40, and the base end pin 32 inserted into the arm 39 is locked at one end of the long hole 30. Movement of the proximal end pin 32 in the elongated hole 30 is prevented.
[0017]
When the push-pull type actuator 31 is housed, the distal end portion 24b of the first arm rotates forward about the pin 26 and the joint portion 22 as shown by a two-dot chain line in FIG. Is bent approximately 90 degrees, and the front portion of the spray tube 17 is stored in a state of being bent forward along the body 12.
[0018]
At this time, since the base end pin 32 of the push-pull actuator 31 is locked at one end of the elongated hole 30, the push-pull actuator 31 does not move and is supported by the push-pull actuator 31. The scatter pipe 17 is prevented from swinging left and right.
[0019]
Here, when the lever 36 is pulled forward, the slider 34 slides on the shaft 33 in the direction away from the pin 28 against the compression coil spring 38 as shown by the solid line in FIGS. The engagement between the notch 35 and the notch 40 is released, and the proximal end pin 32 is unlocked. When the lever 36 is tilted in this unlocked state, the shaft 33 rotates about the pin 28 as shown by a two-dot chain line in the same figure, and the base end pin 32 sandwiched by the arm 39 is moved. It is pressed and moved toward the other end of the long hole 30.
[0020]
Accordingly, the push-pull type actuator 31 is pushed outward and moves along the long hole 30, and the distal end portion 24b of the first arm rotates around the pin 26 toward the outside of the fuselage, and the joint portion 22 is moved. The spread pipe 17 is slightly widened, and the front part of the spray pipe 17 is separated from the body 12 to the outside.
[0021]
Thus, as shown by the two-dot chain line in FIG. 1, even when the scatter tube 17 is stored on the side of the body 12, the front portion of the scatter tube 17 is moved by the operation of the lever 36. , And a gap is formed between the body 12 and the spray pipe 17, so that the operator can easily get on and off. After the operator finishes getting on and off, the lever 36 is returned to the original position, and the front part of the spray pipe 17 is drawn toward the body 12. At this time, the boss 35 of the slider 34 engages with the notch 40 of the plate 29 and is locked by the urging of the compression coil spring 38, and the front portion of the spray tube 17 is locked again in the housed state to the side of the machine body 12. .
[0022]
A stopper 41 is fixed to the rear surface of the base end 24a of the first arm. The tip of the stopper 41 projects beyond the pin 26 toward the other end 24a of the first arm. Have been. Therefore, if the push-pull type actuator 31 is extended while the proximal end pin 32 is in the unlocked state, the distal end portion 24b of the first arm pivots outward around the pin 26, and the first arm When the distal end portion 24b is substantially aligned with the base end portion 24a, the distal end portion 24b of the first arm contacts the stopper 41 and stops rotating.
[0023]
Further, the push-pull type actuator 31 extends until the stroke end is reached, and the base end pin 32 pushes the arm 39 while moving the long hole 30 to one end side, and the lever 36 is pushed back to the body 12 side. As a result, the boss 35 of the slider 34 and the notch 40 of the plate 29 are engaged again, and the base end pin 32 is locked at one end of the long hole 30. Accordingly, the state shown in FIG. 3 is restored, and the scatter tube 17 is expanded to the left and right, and the base pin 32 of the push-pull type actuator 31 is locked. It does not rock.
[0024]
FIG. 7 shows another embodiment, in which a stay 45 is fixed to the upper part of the joint portion 22, a base end of a push-pull type actuator 46 having a relatively long stroke is connected to the stay 45, and a scatter tube is provided. The tip of the push-pull type actuator 46 is connected to a stay 47 fixed in the middle of 17.
[0025]
Thus, when the scatter tube 17 is bent forward of the body 12 at the joint portion 22 and the operator gets on and off when the push-pull type actuator 46 is extended, the push-pull type actuator 46 is extended from the annular body 27 to the first place. The second arm 25 pivots downward, and the front portion of the scatter tube 17 is inclined downward about the joint portion 22. Therefore, the scatter pipe 17 and the supporting wire 48 located at the side of the driver's seat are at a low position, so that the operator can easily get on and off.
[0026]
FIG. 8 shows still another embodiment, in which stays 45 and 51 are fixed in the middle of the scatter tube 17 and one end 52a of an L-shaped arm 52 is pivotally attached to one of the stays 50. The supporting wire 48 is connected to the other end 52 b of the second member 52. Then, the bent portion 52c of the arm 52 is pin-connected to the other stay 51.
[0027]
Thus, when the operator gets on and off, the pin connection between the bent portion 52c of the arm 52 and the stay 51 is released, and the other end 52b of the arm is pressed backward. At that time, the arm 52 pivots rearward around one end 52a of the arm pivotally attached to the stay 50, and the arm 52 is turned over as shown by a two-dot chain line in FIG. It falls down. Therefore, the wire 48 connected to the other end 52b of the arm is relaxed, and the wire 48 does not prevent the operator from getting on and off, and the getting on and off is facilitated.
[0028]
The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.
[0029]
【The invention's effect】
As described above, in the present invention, the base end of the push-pull type actuator connected to the joint is connected to the long hole of the plate. Normally, the base end is locked to one end of the long hole, and when the scatter tube is folded to the side of the fuselage and stored, the base end is unlocked and the base end is removed. When the push-pull type actuator is moved to the other end of the long hole, the push-pull type actuator moves to the outside of the body along the long hole, and the joint portion is slightly expanded to separate the scatter pipe from the body.
[0030]
Thus, it is easy for the operator to get on and off in the state where the spray tube is stored. In addition, since the base end of the push-pull type actuator is normally locked, the push-pull type actuator does not move along the long hole, and either when the spreading tube is expanded or stored. Even if it is, the sprinkling tube can be prevented from swinging.
