Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-film collecting machine, and more specifically, to improve the usability of a multi-film collecting machine by making it possible to adjust the winding speed of a multi-film and to make the cart itself self-running. The purpose of this invention is to improve the work efficiency for collecting multi-films.

[0002]

2. Description of the Related Art Multi-films covered with ridges for promoting the growth of crops need to be peeled off and collected as the crops grow. Conventionally, various multi-film collecting machines have been used for this collecting operation. In general, many multi-film collecting machines rotate a reel on which a multi-film is wound on a truck having wheels by an engine or the like. In addition, in order to move the cart, there is a case where the operator himself pushes the cart or a case where the tension of the multi-film that is wound is used.

FIG. 10 (A) shows that the present applicant has filed a patent application 200
A multi-film collecting machine 1 disclosed in Japanese Patent Application Publication No. 0-135011, in which a winding frame 4 is provided on a carriage 2 having a front wheel 2a and a rear wheel 2b via a rotation regulating frame 3, and , An engine 6 and a winding device 5 are provided. The winding device 5 has a rotating unit 5a to which the reel 8 is attached. The rotating unit 5a is driven to rotate by the engine 6, and sequentially winds the multi-film on the reel 8.

[0004] In addition to the above, a swinging device 9 and a stopping device 7 are provided on the carriage 2. The swinging device 9 is located diagonally above the reel 8, and the swinging lever 9 is moved by the engine 6.
a is swung up and down. The multi-film F is held on a reel 8 via a guide roller 9b provided on a swing lever 9a.
And is swung up and down by the swing of the swing lever 9a, so that it is easily peeled off the ground. Further, the stopping device 7 is located at the rear end of the trolley 2, and when the multi-film F is difficult to peel off from the ground, the multi-film F presses the stopping device 7 due to a change in the peeling angle with the ground. The winding is stopped in conjunction with the control to prevent the cutting of the multi-film F.

[0005] In the multi-film collecting operation by the multi-film collecting machine 1, the multi-film F laid on the ridge U is turned back to the reel 8, and the cart 2 of the multi-film collecting machine 1 located on the side where the multi-film is laid is illustrated. When the operator pushes and moves in the direction of the black arrow in the middle, the multi-film F is wound on the reel 8 rotating clockwise in the figure by the engine 6.

When the both sides of the multi-film F are buried deep in the soil and are difficult to peel off, as shown in FIG. By rotating about the center, the carriage 2 is positioned obliquely. In this state, the operator sometimes pushes the multi-film collecting machine 1 so as to move in parallel with the ridge U on which the multi-film F is laid, and winds the multi-film F from diagonally above.

[0007] Contrary to FIG. 10 (A), the multi-film collecting machine 1 is positioned on the side where the multi-film F is not laid, and the end of the multi-film F is guided to the reel 8.
The multi-film F is taken up by the rotation of the reel 8,
In some cases, the multi-film collecting machine 1 is moved to the laying side by the tension applied to the winding to perform collection.

[0008]

Since the multi-film F is sequentially wound on the reel 8, the radius of the portion where the multi-film F is wound on the reel 8 increases as the operation proceeds. Then, the peripheral speed of the winding position of the reel 8 is proportional to the radius of the wound portion.
However, there is a problem that the winding speed gradually increases even though the rotation speed is constant.

As a result, it is necessary to increase the speed at which the worker moves the bogie in accordance with the increase in the winding speed, and the operator always pushes the bogie while paying attention to the degree of increase in the winding speed. Is changed, and the burden on the worker is increased. Further, when the moving speed of the carriage cannot follow the change in the winding speed, the multi-film is cut without being able to withstand pulling, so that the operation is interrupted.

The above winding speed can be changed to some extent by adjusting the rotation speed of the engine with an accelerator lever. However, the rotation torque required for winding cannot be obtained due to fluctuations in the rotation speed. Adjustment of the winding speed with the accelerator lever is not generally performed because of disadvantages such as an increase in fuel consumption.

Further, the weight of the trolley is increased by the amount of the rewound with the winding of the multi-film, so that the pushing force required for moving the trolley must be increased. That is, since the total weight of the multi-film is usually about 20 to 30 kg, it is necessary for the operator to cope with the increase in the weight at the end of winding as compared with the start of the work, and in addition to the above-described winding speed, It is necessary to cope with the change, which is a factor that increases the burden on workers.

In order to reduce the burden on the worker as described above, the carriage itself is driven by an engine or the like to be self-propelled, and the reel winding speed can be adjusted stepwise. Multi-film collection machines also exist. However, in this multi-film collection machine, the operation position of the bogie is moved away from the position of the take-up speed adjustment unit. It is necessary to adjust the winding speed away from the steering position, so that the work cannot be performed continuously and the workability and usability are poor.

On the other hand, when the direction of the bogie is changed at the end of the ridge or the like, it is necessary to lift the rear wheel straddling the ridge having a height. However, the multi-film collecting machine 1 shown in FIG. The reel 8 whose weight increases due to the picking is located forward of the axis of the front wheel 2a, and the distance between the axes of the front wheel 2a and the rear wheel 2b is also short. Therefore, when the weight of the reel 8 is increased, the weight balance of the bogie 2 is shifted forward, and the movement may be difficult to stabilize. There is a possibility that the vehicle itself is likely to be turned forward.

Further, even when the multi-film is not wound around the reel 8, the heavy engine 6 is provided substantially at the center of the bogie 2, so that a force is required to lift the bogie 2 rearward. There is a problem to be solved. Therefore, regardless of how the multi-film is wound, it is difficult for the operator to lift the rear side of the cart and change the direction.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its first object to improve the usability of a recovery machine by making it possible to adjust the winding speed of a reel steplessly. Another object is to reduce the burden on the worker by making the truck itself capable of self-running. A third object is to make it possible to easily change the direction of the bogie by appropriately adjusting the weight balance of the bogie itself.

[0016]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention includes a multi-film winding means on a carriage including a front wheel and a rear wheel, and a driving means for rotating the winding means. In the multi-film collecting machine, a power required for winding is transmitted by interposing a continuously variable transmission between the winding means and the driving means, and the winding speed of the winding means is freely changed. We provide a multi-film collecting machine characterized by this.

As described above, when the winding means is driven through the continuously variable transmission, the winding speed can be adjusted steplessly. Therefore, even if the winding amount of the multi-film is increased, the continuously variable transmission can be operated. The winding speed can be kept constant. Therefore, the worker can move the carriage without being restricted by the winding speed of the multi-film, and the burden on the worker can be reduced.

The continuously variable transmission is provided between the output pulley and the input pulley between the output pulley attached to the driving shaft of the driving means and the input pulley attached to the driven shaft of the winding means. It has an intermediate pulley that can move in any direction, and the intermediate pulley has an intermediate plate that is movable in the axial direction of the rotation shaft of the intermediate pulley to form two tapered belt grooves. In the groove for the belt, fit the first belt hung on the output pulley, and in the groove for the other, fit the second belt hung on the input pulley, and by moving the intermediate plate by moving the intermediate pulley, The pulley diameter of each belt groove is displaced to change the transmission ratio steplessly.

As described above, the driveless transmission can be transmitted with a simple structure by providing an intermediate pulley in addition to the input / output pulley and the intermediate pulley in addition to the continuously variable transmission, and connecting these with the first and second belts. Since the transmission ratio can be adjusted steplessly by moving the intermediate pulley, it can be applied to a multi-film collecting machine without greatly increasing the cost, and maintenance can be easily performed.

Further, the driving means includes a bogie moving transmission, and the bogie is driven by driving a front wheel and / or a rear wheel, and the continuously variable transmission is the bogie moving transmission. And the winding speed can be adjusted regardless of the moving speed of the bogie. in this way,
When the carriage itself can be driven by the driving means, the worker does not need to push the carriage, and the labor of the worker can be reduced. In addition, the movement of the carriage and the driving of the winding means can be independently adjusted by performing the respective independent shifting means.

Therefore, the winding speed can be appropriately adjusted even if the moving speed of the bogie is increased, and the moving speed of the bogie can be appropriately adjusted even if the winding speed is increased. The picking speed can be independently and appropriately adjusted. It is preferable that the operation lever and the like of the bogie-moving transmission and the continuously variable transmission be provided around a handle gripped by an operator so that various operations can be performed quickly even while the bogie is moving, thereby improving usability.

Also, the multi-film collecting machine of the present invention
A reel around which the multi-film recovered by the winding means is wound is located above the front wheel. If a reel whose weight varies according to the progress of the collection operation is provided at the above position, even if the weight varies, the weight balance during traveling of the bogie is hardly affected and stable movement can be secured. Also, when the direction of the cart is changed, the rear side of the cart can be lifted easily by using the front wheel, which is heavy on the reel, as a fulcrum. If the driving means and the like are also located below the bogie in front of the front wheels, the center of gravity of the multi-film collecting machine can be reduced, and the bogie can be moved more stably.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A multi-film collecting machine according to an embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a multi-film collecting machine 10 according to the present invention, in which front wheels 12a and 12b and rear wheels 13a and 13a,
A take-up frame 15 is provided on a trolley 11 having 3b with a rotation restricting frame 14 interposed therebetween.

On the winding frame 15, a winding device 16 having a rotating portion 35 as a winding means, a swing device 41 having a swing lever 41a and the like, and a stopping device 17 are provided. In the present embodiment, the rotating unit 35 to which the reel 40 is attached is positioned almost directly above the front wheel 12 so that the winding amount of the multi-film does not affect the front-rear weight balance of the cart 11. I have.

An engine 18 and a transmission 19 for moving the truck are fixed as drive means to the front lower side of the truck frame 11a of the truck 11, and right and left handles 20a for workers are provided behind the truck frame 11a. 20b is projected. By arranging the heavy engine 18 and the transmission 19 in the above positions, the center of gravity of the multi-film collecting machine 10 is lowered, and stable movement is ensured.

The driving path of the multi-film collecting machine 10 is as follows.
As shown in FIG. 3, a driving path for moving the bogie from the engine 18 to the front wheels 12a and 12b,
It has a drive path for winding up to the winding device 16 via the continuously variable transmission 31. Engine 1 that is the driving source
The output from the motor 8 is transmitted to the transmission 18 through the centrifugal clutch 21 to the engine 18.

The transmission 19 has an output shaft 19a for driving the front wheels,
19b is provided separately to the left and right, and an output shaft 19c for driving the winding device 16 is also provided. The drive path for moving the carriage is such that drive shafts 22a and 22b are attached to the output shafts 19a and 19b,
The drive wheels sprockets 23a, 23b attached to the ends of the drive wheels a, 22b and the driven sprockets 24a, 24b attached to the axle of the front wheel 12 are connected by a chain 25 to drive the front wheels 12a, 12b. .
The transmission 19 is capable of moving the carriage 11 by changing the speed of the carriage 11 in two forward steps and one reverse step.

As shown in FIG. 4, the support arms 25a, 25b of the front wheels 12 extending from the drive shafts 22a, 22b and the bogie frame 11a are divided into an outer cylinder and an inner cylinder, and extend from the inner cylinder. The distance between the left and right front wheels can be adjusted according to the width of the ridge to which the present recovery machine 10 is applied. The axles 26a, 2a of the rear wheels 13a, 13b
6b has the same configuration as described above, and the distance between the rear wheels can be adjusted according to the front wheels.

On the other hand, the drive path of the winding device 16 is such that an output pulley 27, an intermediate pulley 28, and an input pulley 29 are interposed on an output shaft 19c via a continuously variable transmission 31 composed of first and second belts 30a and 30b. The driving force of the engine 18 is transmitted to a first intermediate shaft 32 which is a driven shaft having a bevel gear (bevel gear) 32a at an end.

Next, a driving force is transmitted to the second intermediate shaft 34 via a vertical shaft 33 having an axis in the vertical direction with respect to the first intermediate shaft 32, and the driving force is transmitted to the end of the second intermediate shaft 34. Sprocket 34a and reel 40
The reel 40 is rotated with the chain 36 interposed between the sprocket 35b of the rotating shaft 35a of the rotating portion 35 to which the reel 40 is attached. The second intermediate shaft 34 is also connected to the swing lever 41a of the swing device 41 by another chain 42, and drives the swing lever 41a.

As shown in FIG. 5, the above-described vertical shaft 33 has bevel gears 33a and 33b provided at both ends thereof, so that the first intermediate shaft 3 located below the bogie frame 11a is provided.
2 is transmitted to the second intermediate shaft 34 located above the take-up frame 15 above the bogie frame 11a. As described above, the driving of the winding device 16 is performed as follows.
Since the shafts 32, 33, and 34 are connected by gears from the continuously variable transmission, the drive path is simplified, reliability is improved, and maintainability is improved. In addition,
The on / off transmission of the driving force of each drive path is performed by the centrifugal clutch 21 or the like, and the left and right front wheels 12a and 12b and the output shaft 19c can be disconnected and connected independently of each other.

The vertical shaft 33 is positioned substantially at the center of the bogie frame 11a in the length direction and at the center in the width direction. By aligning this position with the rotation center of the winding frame 15, the winding is performed. The frame 15 is rotatable about the center of the trolley 11, so that the rotation range is enlarged as compared with the related art. Therefore, the shape of the rotation restricting frame 14 is also changed from a conventional arc shape to a circular shape as shown in FIG.

The continuously variable transmission 31 for continuously increasing and decreasing the number of revolutions of the rotating section 35 of the winding device 16 comprises a bogie frame 11a.
As shown in FIGS. 6A and 6B, the guide of the bogie frame 11a is provided between the output pulley 27 attached to the output shaft 19c and the input pulley 29 attached to the first intermediate shaft 32. An intermediate pulley 28 is rotatably mounted on a holder 45 provided to be movable back and forth on the bar 11b. The holder 45 has a rod 4
6 is attached, and the other end of the rod 46 is
It is connected to a shift lever 50 attached near the handles 20a, 20b at the rear end of the bogie 11, and the rod 51 is moved forward and backward by moving the shift lever 50 up and down, and the intermediate pulley 28 is also moved.

The intermediate pulley 28 includes side plates 28a on both sides,
An intermediate plate 28c that is movable in the axial direction of the rotation shaft 28d of the intermediate pulley 28 is provided between the intermediate pulleys 28b, and two belt grooves 29a and 29b are formed. Since the first and second belts 30a and 30b used in the continuously variable transmission 31 use V-belts having a trapezoidal cross section, the side plates 28
The belt contact surfaces of a, b and the intermediate plate 28c are formed in a tapered shape that matches the trapezoidal inclined belt side surface. The belt grooves of the output pulley 27 and the input pulley 29 are also formed in a tapered shape.

One belt groove 29 of the intermediate pulley 28
a, the first belt 30 hung on the output pulley 27;
a, and the second belt 30b hung on the input pulley 29 is fitted into the other belt groove 29b.
The driving force of the output shaft 19c is transmitted to the first intermediate shaft 32.

The speed of the continuously variable transmission 31 is controlled by the intermediate pulley 2
This is done by moving the position 8 back and forth. FIGS. 6A and 6B show a state in which the intermediate pulley 28 is located on the front side. In this state, one belt groove 29a on which the first belt 30a is fitted has a maximum pulley diameter. On the other hand, the other belt groove 29b in which the second belt 30b is fitted has a minimum pulley diameter.
In this state, when the shift lever 50 is operated to pull the rod 46 rearward, the intermediate pulley 28 moves rearward as shown in FIGS. 7A and 7B.

In this state, the center distance between the output pulley 27 and the intermediate pulley 28 is increased by the movement of the intermediate pulley 28 as compared with the state shown in FIGS. 6A and 6B. The belt length of the first belt 30a connecting the pulley 27 and the intermediate pulley 28 is constant. Therefore, in order to absorb the increase in the inter-axis distance, the pulley diameter of the belt groove 29a must be reduced, and the intermediate plate 28c moves toward the side plate 28b with the movement of the intermediate pulley 28. are doing. On the other hand, the axial distance between the input pulley 29 and the intermediate pulley 28 is, conversely, reduced by the movement of the intermediate pulley 28. To cope with this reduction, the pulley diameter of the belt groove 29b must be reduced. The diameter of the belt groove 29b must be increased by moving the intermediate plate 28c.

Due to the fluctuation of the belt grooves 29a and 29b, the transmission ratio from the output shaft 19c to the first intermediate shaft 32 is also continuously and continuously displaced. That is, since the belt contact surfaces of the side plates 28a, 28b and the intermediate plate 28c of the intermediate pulley 28 are tapered, the contact position of the belt moves continuously along the belt contact surface, so that the transmission is continuously and continuously. The ratio is adjustable. Therefore, the winding speed of the winding device 16 can be adjusted steplessly by moving the intermediate pulley 28 back and forth. The position of the intermediate pulley 28 in FIGS. 6A and 6B is in a low speed state, and FIGS. 7A and 7B are in a high speed state, and the intermediate pulley 28 is at an arbitrary position on the way from the front side to the rear side. While holding, the winding speed can be set arbitrarily in a range from low speed to high speed.

On the other hand, various operation levers and the like are provided around the left and right handles 20a, 20b on the rear side of the carriage 11 where the worker is located, and as shown in FIG.
Is provided with a shift lever 50 of the continuously variable transmission 31 for moving the intermediate pulley 28 described above, and a shift lever 51 for movement of the transmission 19 is provided inside the left handle 20a. Furthermore, left and right handles 20a, 20
Side clutch levers 51a and 51b for turning on and off transmission of the left and right front wheels 12a and 12b are provided at the end of b.

In addition, an engine accelerator lever 53 is provided at the right end of the joint bar 52 connecting the left and right handles 20a, 20b, and the engine is turned on / off in the vicinity thereof.
A switch 54 and a gripper 55 of a starter rope 55a are arranged, and a take-up device clutch lever 56 for turning on and off the transmission of the take-up device 16 is provided at the center. Since all the levers necessary for the operation of the multi-film collecting machine 10 are arranged around the left and right handles 20a and 20b in this way, if the operator is at the handle position during the work, all the operations necessary for the work can be performed. It can be carried out.

The stop device 17 and the locking of the rotating position of the winding frame 15 other than those described above have the same structure as the conventional one.

Next, the above-mentioned multi-film collecting machine 10
The multi-film collecting operation using the method will be described with reference to an example in which the multi-film shown in FIG. First, the front wheel 12 of the multi-film collecting machine 10
The distance between the rear wheels 13a and 13b and the rear wheels 13a and 13b is adjusted to the width of the ridge on which the present recovery machine 10 moves, and is positioned parallel to the laid multi-film F. Next, the take-up frame 15 is rotated to set the angle at which the multi-film F is peeled off obliquely, and the end of the multi-film F is turned back to stop the stopping device 17 and the rocking device 41 of the present collecting machine 10.
Is wound around the reel 40.

In this state, the starter rope 55a is pulled to rotate the engine 18, and the shift lever 51 for movement is used to move the carriage 11 forward. In addition, the rotation part 35 of the winding device 16 also starts rotating with the start of the engine 18 to start winding the multi-film F. However, the multi-film F is loosened or over-stretched in accordance with the moving speed of the carriage 11. In order not to be in the state of being turned, the shift lever 50 is operated to adjust the winding speed to an appropriate value.

In the above state, the truck 1 is driven by driving the engine.
By moving 1, the multi-film F is sequentially wound up on the reel 40. Further, if the winding amount of the multi-film F increases and the winding speed becomes too high with respect to the moving speed of the cart 11, the optimum winding speed can be set by simply operating the shift lever 50. ing.
As described above, since the recovery machine 10 runs on its own, the worker S does not need to push the carriage 11 to move it, and only needs to lightly attach the hands to the handles 20a and 20b for fine adjustment of the direction. Further, there is no need to change the moving speed of the bogie in response to the change in the winding speed, so that the burden on the operator involved in the collection operation is reduced.

When the direction of the collection machine 10 is changed at the end of the ridge, as shown in FIG.
It is necessary to raise the rear side so that one rear wheel 13a passes over the ridge U. However, the reel 40 is
Since it is located above a and b, even if a large amount of multi-film is wound on the reel 40, the load on the front wheels 12a and 12b serving as a fulcrum of lifting is increased, and the force required for lifting is affected. Absent.

Further, since the heavy engine 18 and the transmission 19 are located in front of the front wheels 12a and 12b, they can be easily lifted regardless of the winding amount.
When the direction is changed, the handlebars 20a and 20b are gripped and lifted, and the side clutch lever in the direction in which the driver wants to turn is gripped to cut off the drive of one of the front wheels so that the vehicle can bend with a small turning radius.

When it is not desired to move the carriage 11 alone and rotate the rotating portion 35 of the winding device 16, when the clutch lever 56 for the winding device is gripped, the drive to the rotating portion 35 is interrupted. , So that it can respond appropriately when the film is entangled. In addition, in addition to the above, if the take-up frame 15 is arranged in parallel with the bogie frame 11a without rotating the take-up frame 15, the multi-film can be moved by moving on the ridge on which the multi-film is laid as in the related art. Of course, the present invention can be applied to the collecting operation.

Further, the present recovery machine 10 is not limited to the above-described embodiment, and when it is necessary to reduce the overall length, the engine position and the like do not necessarily need to be located in front of the front wheels, and the driving force In order to increase the driving power, the rear wheels may be driven together with the front wheels, or the rear wheels may be driven depending on the use condition. Note that a motor other than the engine can be used as the driving means. Furthermore, only the continuously variable transmission described above may be applied to a conventional type of collecting machine in which a worker pushes a bogie, so that the worker can work without adjusting the moving speed of the bogie to the winding speed. .

[0049]

As is apparent from the above description, by applying the multi-film collecting apparatus according to the present invention, even if the winding speed increases with the increase in the winding amount of the multi-film, the continuously variable transmission can be realized. The operator can adjust the winding speed to the required speed by the machine, so that the collecting operation can be performed regardless of the winding speed. Moreover, since the above adjustment can be performed in a stepless manner, the rotation speed can be finely adjusted as appropriate according to the work situation, and the burden on the operator can be reduced.

Further, in the present collecting machine, the truck itself can be moved by using the engine for driving the winding device also for moving the truck, so that there is no need for the operator to push the truck. Work load can be reduced. Also, since the moving speed of the bogie and the winding speed of the winding device can be changed independently without interlocking, the moving speed of the bogie can be kept constant even if the winding speed is adjusted. , Stable and efficient collection work can be performed.

In addition, according to the present invention, since the rotating portion for attaching the reel is disposed above the front wheel, even when the weight is increased by winding the multi-film, the weight balance is hardly affected. When the direction of the truck is changed, the rear side can be lifted with almost the same force as when the vehicle is empty, and the handling of the multi-film collecting machine can be ensured. In addition, a heavy engine, etc., should be located in the lower front part of the bogie to reduce the center of gravity to enable stable movement, and to arrange levers, etc. necessary for various operations around the handle gripped by the operator. Thus, the operability can be improved and the working efficiency can be improved.
