Description

[Detailed explanation of the idea] TECHNICAL FIELD The present invention relates to a control and riding device for a crawler-type layered work machine.

When attaching a riding device to an agricultural machine that runs on a tracked vehicle, the seat on which the operator 75 rides is placed in a parallel 4-way position.
It is connected to the fuselage via a joint link, and in order to prevent the operator from being in a dangerous situation during operation, the parallel four-joint link is configured so that it does not swing upward beyond a predetermined range. In a device having such a configuration, the parallel four-bar link can swing smoothly, and the stopper mechanism for restricting the upward swing is robust and operates accurately.

Hereinafter, an embodiment whose details are shown in the drawings will be described.

Figure 1 shows a side view of a combine harvester, which is one of the crawler-type layered working machines.If the rear riding device B is removed, it is a walk-behind combine harvester. A threshing device is installed on the right side of the machine body supported by 1, and a reaping conveyance device H is installed on the left side. The cutting body 9, the cutting blade 10, the lower conveying chain 711, and the tip conveying tines 12 are arranged and constituted, respectively, and the culm base receiving plate 14 is extended rearward from below the foot chain 13 and the pinning rod 13' in the threshing device. , the engine 15 is located below the receiving plate 14.
A paddy receiving device 16 is constructed at the rearmost part of the machine body behind the threshing device, with a paddy receiving stand 16a installed below and a discharge tube 16b above.

Further, a control section A is provided at the rearmost part of the machine body behind the reaping and transporting device H. Below the control section A, a left end portion of the horizontal pipe frame 4 supported by a support 17 on the machine base side is provided. The fixed connecting metal 18 is fitted and fixed to the lower part of the pipe frame 19 which is erected in a triangular shape on the side to form a support frame F.
The split connecting bodies 20 and 20' are joined together over the upper part of the pipe frame 19, and fixed with bolts 21, and the support shaft 7 with one end fixed to the inner connecting body 20 is attached to the pipe frame 19. A locking dowel 22 is removably inserted above the frame 4 and extends in the lateral direction of the fuselage, with its tip being a free end, and the operating lever 3 is installed on the upper part of the pipe frame 19 in the support frame F. The control box 3 is mounted to support the control box 3, and the box 3 is supported by a pipe frame 23 bent and extended from the fuselage side. Configure A.

B shows a riding device, in which a grounding wheel of a large-diameter wheel is rotatably mounted below the lower support 25 of the seat 24 by a fork body 26; In contrast, the caster structure allows for free rotation.
At the top and bottom of the support body 25, there are support shafts 27.27.
' Attach each.

Mounting brackets 6,
6 are installed at intervals, but both metal fittings 6,
6 is two symmetrical metal fittings 5a96b that are attached to the pipe frame 4 and connected by bolts 28, and are attached to the pipe frame 4 so as to be freely rotatable. Hinches 5, 5 each consisting of two parallel plates are fixedly installed, and locking pins 29, 29 can be removably fitted into the hinges 5, 5 in the vertical direction.

A parallel four-bar link C is constructed between the control section A side and the passenger equipment B side by setting the two support shafts 27, 27', the support shaft 7, and the pipe frame 40 axis at four points. The rear ends of the upper and lower upper links 2 and lower links 2' are rotatably connected to the support shafts 27 and 27', respectively, and a side-angled wide connecting body 30 is fixed to the tip of the lower link 7. Then, the connecting body 30 is fitted into both the hits 5, 5, and the locking pins 29 and 29 are removably fitted thereinto, and a cylindrical metal 31 that can be fitted into the support shaft 7 is provided at the tip of the upper link 2. One end is fixed in the perpendicular direction, and a step 32 for placing a foot in the horizontal direction is made of pipe and fixed in the lower part near the tip of the lower link 2'.

Thus, when the upper link 2 and the lower link 2' are removed, the combine harvester becomes a walking type combine harvester, and the operator can follow the combine while walking and operate it using the control section A.

In addition, the cylindrical metal 31 at the tip of the upper link 2 is connected to the support shaft 7.
The locking pin 22 is fitted into the support shaft 7 to prevent it from being removed, and the connecting body 30 at the tip of the lower link 2' is inserted into both hinges 5, 5 to lock it. Stop pin 29, 29
When inserted, the riding device B can be attached to the rear of the control unit A, and an operator sitting on the seat 24 can put his feet on the step 32 and operate the riding device B.

Therefore, even if the grounding wheels are in contact with the ground and rolling while following the aircraft and swing up and down due to unevenness in the field and road surface, the riding device B is supported by the parallel four-bar link C, so the riding device B can move up and down. The operator can operate the control unit A without worsening his or her posture with respect to the control unit A by swinging parallel to the direction.

In addition, even if the aircraft together with the traveling body 1 tries to tilt significantly forward and backward, immediately after the aircraft has crossed the ridge, the weight and force of the operator sitting on the riding device B will be affected, and the front two of the parallel four-bar link C will be affected. The point, that is, the rear part of the machine at the support shaft 7 part and the pipe frame 4 part receives a downward tensile load, and the machine body is prevented from tilting forward too much and can run stably, allowing the combine to be placed on a trailer. In the case of loading, when ascending a long slope with the front of the aircraft facing upwards, the passenger device B can easily follow the plane using the parallel four-bar link C, and the passenger device B, which carries the weight of the operator, can easily follow the plane. The weight on the device B side does not affect the aircraft body and can be operated without damaging the balance of the aircraft body.

As shown in FIGS. 5 and 6, a stopper plate 33.33 is joined to the upper surface of the connecting body 30, a bottle 32.32 is inserted thereinto, and a stomper S is attached.

For example, even if the machine body and the traveling body 1 try to tilt significantly forward and backward when crossing a ridge, the front bent part 33 of the stopper plate 33 will collide with the stopper rod 31, preventing further relative rotation. This prevents the aircraft from tilting significantly, and also prevents the operator's feet from coming into contact with the aircraft.

A control section A is provided at the rear of the aircraft having the track type traveling body 1,
In a crawler-type layered work machine configured such that a riding device B having a ground contacting wheel at the lower part can be connected to the rear of the control section A via a parallel four-bar link C, the lower link 2 of the four-bar link C is provided. ' is formed by forming a wide connecting body 30 in the direction perpendicular to the horizontal and lateral direction with respect to the longitudinal direction of the lower link 2' on the body connecting side of the tip, and this is formed into a wide connecting body 30 in the direction perpendicular to the lower link 2' The four-bar link is connected to the left and right hits 5, 5, which are rotatably fitted into the pipe frame 4, respectively, and the four-bar link is connected to the pipe frame 4 and the wide connecting body 30 within the interval between the left and right pinches 5, 50. Since the stopper S is provided to limit only the upward swing above a predetermined range of C, even if the aircraft body swings during driving or the passenger equipment B swings, it can be stably followed. The operator seated on the seat can operate the vehicle safely and reliably, and even if the aircraft along with the traveling body 1 changes its tilt forward to high or backward, the stopper S will collide with the stopper S to prevent the tilt from becoming steeper than a certain level. The passenger device B can be supported by the vehicle to allow stable running, and the operator can operate the vehicle safely without the passenger device B swinging upward more than a certain amount with respect to the aircraft body.

In addition, since the running section of the agricultural machine is a tracked running body, when it goes over a ridge, the front part of the running body tilts lower and a force is exerted on the riding equipment side, but the downward swinging of the riding equipment is prevented by the stopper S. The operator can sit safely even when crossing a ridge.

Moreover, the lower link 2 of Stomper S&'L 4-section link
Since it is formed between the rotation connecting parts 5 and 5 installed at the left and right intervals at the sleeve end, the intended operation is performed accurately without causing any damage to the engagement and disengagement action, and the stopper is ``With the two lower links, the stopper is inevitably set and held at the desired position, making the mounting operation easy, and the stopper has a compact and robust structure, which provides practical effects.
