Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an improvement of a transporting device for transporting vinyl-wrapped roll-shaped hay for stacking.

Conventional Technology and Problems Pasture is cut, dried, and hay is rolled, then rolled into a large roll, wrapped in vinyl, and left in the grass field. The neglected vinyl-wrapped roll-shaped hay is collected, loaded into a transport vehicle such as a trailer, and transported to the vicinity of a livestock barn for open-field loading.

In this hay field loading work, the hay is unloaded from the carrier by the transport device equipped in the hydraulic mechanism of the tractor and transported to the field loading location for field loading.

The well-known transporting apparatus described above has a known configuration shown in FIG. 5, FIG. 6, FIG.

The transporting device shown in FIG. 5 (hereinafter referred to as “first conventional technology”)
Is a flat surface that spreads one end of a pair of left and right embracing plates 1'on the front of a mounting plate 6'that is attached to a hydraulic mechanism (not shown) of the tractor. Fixedly disposed in a fixed shape, and the vicinity of one end of a pair of left and right hugging arms 2'formed by a circular tube is pivotally attached to the other end of the hugging plate, and the one end of the hugging arm and the mounting plate 6 are attached. A hydraulic mechanism 3'is arranged over both the left and right sides of the ', and the hydraulic mechanisms are configured to operate simultaneously.

According to the first conventional technique, the pair of left and right holding arms 2 '
Since it is formed of a circular tube, the contact surface with the vinyl-wrapped roll-shaped hay is reduced, the hay easily slips off, and it often slips off when lifted from the carrier, and the vinyl may tear. . Further, since the pair of left and right hydraulic mechanisms 3'are configured to operate simultaneously, they are not configured to operate independently, respectively.
When the center line of the tractor is aligned with the center of the roll-shaped hay, the pair of left and right hugging arms 2'actuate left and right at the same time. If you try to hold the hay while the center line of the tractor does not match, the pair of left and right hugging arms 2'actuate simultaneously unequally on the left and right (as an example, in FIG. 5, from the solid line position to the virtual line position). So that they work simultaneously unequally). If the left and right hydraulic mechanisms 3'can be independently operated, the uneven operation of the hugging arms 2'can be operated independently after the uneven operation, so that the center of the hay reaches the center line of the tractor. The hay can be carried by pushing the hay with one of the hugging arms 2'and then simultaneously activating a pair of left and right hydraulic mechanisms 3 '. Since each of them can not operate independently, the hay that has been held in an inclined manner becomes easy to slide down, and when it is lifted from the carrier, it slides down.
It's not unusual to tear vinyl. Since the roll-shaped hay is usually stored in a plurality of tiers (three tiers as an example) and stored, it is necessary to properly align the hay to prevent it from collapsing. You have to do it. However, in the first prior art, since the left and right hydraulic mechanisms 3'only operate simultaneously and cannot operate independently, only one hugging arm 2'operates in order to align them in the case where the field loading forms are not uniform. Even if it is desired to push the hay to the normal position at least, both hugging arms 2'cannot be pushed because they are simultaneously operated, and it is difficult to correct the uneven stacking form.

A transporting device shown in FIG. 6 (hereinafter referred to as second prior art)
Is fixed to the front side of the mounting plate 6'that is mounted on the hydraulic mechanism (not shown) of the tractor, and the holding plate 1'is fixedly arranged toward the front side. In this configuration, a wrapping concave surface 1'-1 for grass-like hay is formed, and a sandwiching plate 2'which can reciprocate in a direction parallel to the mounting plate 6'is provided at a portion facing the wrapping surface.

According to the second conventional technique, the above-mentioned hay is pressed against the holding concave surface 1'-1 of the holding board 1'by the holding board 2 ', and is intended to be sandwiched and carried. 1. Compared with the prior art, since the wrapping force is weaker, the hay is more likely to slip off, and when it is lifted from the carrier, it often slips off and tears the vinyl. Further, since the sandwiching plate 2'is provided at a portion of the embracing plate 1'close to the embedding concave surface 1'-1 and closer to the mounting plate 6 ', the embracing plate 2'can be embraced even if it is desired to correct the uneven stacking form. It is difficult to insert the sandwiched plate 2'between the hay stacked in the open because the plate 1'is an obstacle, and it is difficult to correct the open stacking form.

The transporting device shown in FIG. 7 (hereinafter referred to as the third prior art)
Is a configuration in which the holding plate 1'of the second prior art is changed to a sandwich plate 2 ', and in a front portion of the mounting plate 6'which is mounted on a hydraulic mechanism (not shown) of the tractor, a direction parallel to the mounting plate 6'. In this configuration, a pair of left and right sandwiching plates 2'that can reciprocate are provided.

According to the third conventional technique, the pair of sandwich plates 2 '
By having the above, even if the roll-shaped hay cannot be held, the sliding force is improved as compared with the second conventional technique,
If the hay is pinched too strongly, the vinyl may tear, and if the grip is weakened, the hay may slip easily. Even if it is desired to correct the uneven form of open stacking, the pair of sandwiching plates 2 ′ is short and the pair of sandwiching plates cannot be moved forward. Since the plate 2'cannot be inserted to a sufficient depth, it is difficult to correct the above-mentioned open stacking form.

The present invention has been made in view of the above-described circumstances, and provides a useful transporting device that is unlikely to cause slipping accidents of vinyl-wrapped roll-shaped hay and that can easily correct an uneven stacking mode. With the goal.

Means for Solving the Problems In order to achieve the above-mentioned object, a means for achieving the above-mentioned object is to mount a holding frame, which has a substantially semicircular shape in a plane, on a hydraulic mechanism of a tractor, with its concave surface facing the front side. The pair of left and right hugging arms, which are composed of, are pivotally attached to the left and right ends of the hugging frame, and the base ends of the left and right hugging arms are attached to the rear side of the hugging frame. A hydraulic mechanism is installed over both ends,
That is, the hydraulic mechanism is connected to a solenoid valve, and the solenoid valve is electrically connected to a changeover switch for a hydraulic circuit.

Action Since the pair of left and right hugging arms are made up of rectangular tubes, the contact surface with the vinyl-wrapped roll-shaped hay is increased, and the hay is held by the hugging arms, and the concave surface of the substantially semicircular hugging frame is used. Since it becomes possible to hold the hay toward, the contact surface between the wrapping frame and the hay is increased, so that the hay is firmly held. Then, a pair of left and right hugging arms are pivotally attached to the hugging frame, hydraulic mechanisms respectively arranged over the hugging arms and the mounting frame are connected to solenoid valves, and the solenoid valves are electrically connected to a changeover switch. Due to the connection, when the changeover switch is switched, the solenoid valve is operated to enable simultaneous or independent operation of the hydraulic mechanisms, and the center of the hay and the center line of the tractor do not match. Also, it is possible to change the position of the early hay with both or one of the hydraulic mechanisms and the hugging arm so that the center of the hay can be aligned with the center line of the tractor.

Example A known hydraulic mechanism t provided in a tractor (not shown)
The hugging frame 1 attached to (boom, hydraulic cylinder, etc.)
It is fixedly arranged on the front surface of the rectangular mounting frame 6, and is mounted on the tractor by being mounted on the hydraulic mechanism t of the tractor. The hugging frame 1 is formed in a substantially semi-circular shape in plan view, and the concave surface thereof is fixedly arranged on the front surface of the mounting frame 6 with its front side facing forward, and the roll-shaped hay wrapped in vinyl cooperates with the pair of left and right hugging arms 2. And hold it firmly. The pair of left and right hugging arms 2 is formed by a rectangular tube so as to increase the contact area with the hay, and the vicinity of the base end is axially attached to the left and right ends of the hugging frame 1 by pins 7 to form a horizontal plane. The left and right hydraulic mechanisms 3 are arranged over the base end and the left and right ends of the mounting frame 6, and when the hydraulic mechanism operates, the pin 7 is centered. It is configured to rotate in a horizontal plane, so that the hay can be firmly held by the cooperation with the hugging frame 1 without worrying about slipping down, and the position of the hay stacked unevenly can be adjusted. Alternately, the center of the hay can be aligned with the centerline of the tractor. The pair of left and right hydraulic mechanisms 3 are for moving the pair of left and right hugging arms 2, and are arranged over the base end of the hugging arms and the left and right ends of the mounting frame 6. The hydraulic mechanism 3 is of a double-acting type as shown in FIG. 4, is connected to each solenoid valve 4, is configured to operate when these solenoid valves are operated, and is connected to each control box 8. It is configured so that it can be operated by operating the box. The solenoid valve 4 may be a well-known one (for example, a DC normally open shutoff valve may be used), and is electrically connected to a changeover switch 5 provided in the driver's seat of the tractor to operate the switch. Configure to work with. The changeover switch 5 has two operating parts A and B. When the operating part A is turned on, the solenoid valve 4 is operated to close the A ′ side hydraulic circuit, and when the operating part B is turned on, the solenoid valve 4 is turned on. 4 is operated and the hydraulic circuit on the B'side is closed,
When both A and B are turned off, the solenoid valve 4 is operated and the A'side hydraulic circuit and the B'side hydraulic circuit are opened simultaneously. Therefore, if one of the operation parts A and B is turned on and the other is turned off, the hydraulic circuit of the one turned on is closed, the hydraulic circuit of the one turned off is opened, and one hydraulic mechanism 3 If both operation parts A and B are turned off at the same time, the pair of hydraulic mechanisms 3 can be operated at the same time. The changeover switch 5 is electrically connected to a power source mounted on the tractor. The control box 8 is well known and is arranged in the driver's seat of the tractor and is connected to an oil tank, an oil pump, etc. mounted on the tractor.

Effect of the Invention Since the present invention is configured as described above, it has the following effects.

(1) A pair of left and right hugging arms composed of rectangular tubes and a flat, substantially semi-circular hugging frame work together to hold the vinyl-wrapped roll-shaped hay firmly. The above-mentioned hay is less likely to slip off during transportation and when loading in the open field, and the risk of tearing the vinyl is minimized.

(2) Simultaneous operation and independent operation of the left and right hydraulic mechanisms respectively arranged over the pair of left and right hugging arms and the mounting frame can be performed, so that the hay loaded on the transport vehicle can be centered or misaligned. Even if the center of the hay stacked in the field and the center line of the tractor do not coincide with each other, both or one of the hydraulic mechanisms and the hugging arm are operated to change the position of the hay,
If the center of the hay is aligned with the center line of the tractor, in the case of hay loaded on the former carrier, the hay can be carried in the hay and carried in the open field without worrying about the hay slipping down. In the latter case, when the hay has been piled up in a random arrangement, the tearing of the vinyl is eliminated, and the form of the piles is aligned, there is no fear of collapse, and the gap between the stacked hay is reduced, and rainwater is It becomes difficult to enter.

(3) Since it is composed of a frame body such as a hugging frame, a hugging arm, and a mounting frame, the weight can be reduced, and the medium tractor or the small tractor can be equipped.
