Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a bucket with a two-way presser that scoops up garbage such as empty boxes, snow, and other cargoes with low specific gravity and large volume and compresses them in two directions: the height direction and the width direction.

[Conventional technology]

Loading cargo using a regular loader bucket
During transportation work, when the cargo has a low specific gravity such as empty boxes, garbage, snow, etc., conventionally, the cargo is scooped into a bucket as is. This results in a significant reduction in work efficiency relative to the volume of the bucket. The cargo scooped up in a bucket is then loaded directly onto a dump truck or transported and dumped at a predetermined collection location, which requires a large-capacity dump truck and collection location, making it difficult to utilize space effectively. There was also the problem of poor economic (investment) efficiency.

[Problem that the invention attempts to solve]

This idea was devised in view of the above circumstances, and its main problem is to reduce the volume of cargo that has a low specific gravity and large volume by compressing it in two directions: the height direction and the width direction. It is to provide a bucket with a pressa.

[Means to solve the problem]

This invention solves the above problems by: (a) equipping the running body with a bucket main body via a bucket support mechanism; (b) providing an upper press plate that can freely move up and down above facing the bottom of the bucket main body. (c) A height direction pressing drive unit is provided on the bucket main body to lower the upper press plate to press the cargo inside the bucket main body and return it to its original position; (d) a side surface of the bucket main body; (e) The bucket main body is provided with a side press plate that can reciprocate in the width direction, and when the side press plate is moved laterally and presses the cargo inside the bucket main body, We are taking technical measures to return it to its original position.

[Effect]

As a result, after scooping a cargo with a low specific gravity into the bucket, when the upper press plate is pushed down by the height direction pressing drive unit provided on the bucket main body, the upper press plate presses the cargo from above. As a result, large and bulky cargo objects with low specific gravity are compressed into a compact size in the height direction. Similarly, when the side press plate is moved laterally by the width direction pressing drive unit provided on the bucket main body, the press plate applies pressure to the cargo from the side, and the cargo is moved in the width direction. is also compactly compressed.

Similarly to the upper press plate 12, this side press plate 13 also has a horizontal guide portion G2.
is provided. In the case of this embodiment, as shown more clearly in FIG.
and guide runners G22 extending in the left-right direction at both rear ends of each side press plate 13, and the guide runners G22 are slid along the guide grooves G22. In order to smooth the sliding motion by the guide parts G21 and G22, a sliding smoothing means is provided on the sliding surface of the side press plate 13 side and/or the bucket main body 10 side in this embodiment. The guide rollers R, R are rotatably supported by the guide runner G21, so that the guide rollers R, R smoothly slide on the peripheral wall of the guide groove G22. In the present invention, the positions and configurations of the guide parts G1 and G2 are not particularly limited, but in short, the upper and side press plates can be moved to apply pressure reliably, and after pressurization, they can be smoothly returned to the original standby position. Of course, any other known guide means may be used as long as it has a configuration for returning it. Incidentally, a large number of small convex portions may be integrally provided on the opposing surfaces of the side press plates 13, 13 in a dotted manner so as to facilitate compressing the cargo by applying pressure. In the case shown in FIG. 1, the upper press plate 12 is connected to the tip of a piston rod of a hydraulic cylinder which is disposed in a hollow inverted manner above it and serves as the height direction pressing drive unit 2, and is connected to the base via a pin p'. The hydraulic cylinders 2, 2 are connected to the upper surface of the end side.
It is supported by a support portion 6 extending upwardly and bending forward on a pair of left and right frames 10F welded to the rear of the back plate of the bucket main body 10. Therefore, the extension of the piston rod by the hydraulic cylinders 2, 2 directly pushes down the upper press plate 12 to compress the cargo, and the contraction of the piston rod causes the upper press plate 12 to be pushed down directly.
can be raised and returned to its original standby position. Here, in order to stably and efficiently compress the cargo in the bucket cart 10 with the press plate 12 when the upper press plate 12 is lowered by the extension operation of the hydraulic cylinder 2, the piston rod of the hydraulic cylinder 2 is moved to the upper part as shown in the figure. Press plate 12
It is preferable to connect it closer to the rear end side. In the case shown in FIGS. 6a and 6b, the upper press plate 12 is pressed downward by the upper connecting arm part 4 driven by the height direction pressing drive part 2, and after being pressed, returns to the original standby state. Return to position. That is, in the illustrated example, the upper connecting arm 4 is made of a substantially long and short metal plate, and one end is connected to the tips of the piston rods of the pair of left and right hydraulic cylinders 2, 2, and the other end is connected to the guide of the upper press plate 12. It is connected to runner G12. Further, the upper connecting arm portion 4 may be molded separately from the pressing drive portion 2 as in this embodiment, or may be molded integrally. This height direction pressing drive section 2 is connected to the back plate of the bucket main body 10 via a support section 6. That is, in the case of FIG. 6a, the hydraulic cylinders 2, 2
is arranged in an upright manner, and the tip of its piston rod is pivotally connected to one end of the connecting arm 4, and the base end of the cylindrical portion of the hydraulic cylinders 2, 2 extends from the back of the bucket main body 10 to the rear. It is pivotally connected to a bracket that protrudes in the direction and serves as a support portion 6. On the other hand, in the back plate 10A of the bucket main body 10, a pair of connecting arm passing grooves (not shown) are perpendicularly perpendicular to the left and right from the upper end to a midway position so as not to obstruct the vertical movement of the upper connecting arm 4. be. In the case of FIG. 6b, the hydraulic cylinders 2, 2 are arranged in an inverted manner, and the tips of their piston rods are connected to the guide runner G12 of the upper press plate 12 via the connecting arm 4. Therefore, as the piston rod of the hydraulic cylinder 2 expands, the upper press plate 12 is pushed down. Next, the side press plates 13, 13 are connected to a pair of hydraulic cylinders 3, 3, which serve as widthwise pressing drive units, which are arranged in parallel in opposite directions with their piston rods facing outward, as shown in FIGS. 3 and 5. Since the tip of the piston rod is inserted into the guide groove G21 from the inside and connected to the guide runner 22, it can be directly driven by the expansion and contraction of the hydraulic cylinder 3. In place of the above configuration, a hydraulic cylinder 3 (not shown)
and the side press plate 13 may be connected via a connecting arm. In this case, it is necessary to drill a connecting arm passage groove extending horizontally on the back plate of the bucket main body or on the outer wall surface of the horizontal guide groove. In addition, 10E in the figure is a bracket integrally connected to the upper rear surface of the back plate 10A between the frames 10F by means such as welding, and the lower end of the frame 10F and the bracket 10E are connected to the bucket support mechanism K.
The lift arm L and the tilt link T are connected to each other by pins P. Next, the operation of the above embodiment will be explained. Hydraulic cylinders 2, 2 that serve as the height direction pressing drive unit
With the upper press plate 12 held at the standby position (solid line position in the drawing) on the upper opening side of the bucket main body 10, the presser-equipped bucket 1 is lifted down to the ground position and the wheel loader H is
When the bucket 10 moves forward, cargo with a small specific gravity is scooped into the bucket 10. When the hydraulic cylinder 2 is extended after scooping, the upper press plate 12 (third
By performing a downward movement (at the dot-dash line position in FIG. 7) and pressurizing the cargo in the bucket 10 from above, the cargo is compressed into a compact size. At this time, in the case shown in FIG. 6, the upper connecting arm 4
Since the upper press plate 12 passes through the vertical connecting arm passing groove 5 formed in the bucket main body 10, the upper press plate 12 can be moved up and down without colliding with the bucket main body 10. When the upper press plate 12 is raised and lowered, the guide runners G12 and guide rollers R on both sides thereof
By sliding in the guide groove G11 of the bucket main body 10, the upper press plate 12 can move up and down smoothly within the bucket 10 in the vertical direction. Similarly, when the piston rods of the hydraulic cylinders 3, 3, which serve as the widthwise pressing drive section, are operated to extend,
The side press plates 13, 13 on both sides move from the standby position (solid line position in the drawing) toward the center of the baguette main body to reduce the width (to the position shown by the one-dot chain line in Figure 1 and the two-dot chain line position in Figure 3), Since the cargo in the bucket 10 is pressurized from the side, the cargo is sequentially compressed into a compact size from both the vertical and horizontal directions. In addition, when the side press plate 13 moves laterally, the guide runners G22 and guide rollers R on both sides slide in the guide groove G21 of the bucket main body 10, so that the side press plate 13 moves horizontally inside the bucket 10. can be moved smoothly. During such work, the cargo scooped up by the bucket 10 is placed on the back plate 10A of the bucket 10.
Although it swells higher toward the other side, the pressurizing force of the hydraulic cylinders 2 and 3 acts on the swell side, that is, closer to the rear end of the press plate, so that the entire cargo is stably and efficiently compressed. In this way, cargo having a low specific gravity and large volume is compressed in the bucket 10, and the compressed cargo is loaded onto a dump truck or transported and dumped at a predetermined collection site. In addition, in this invention, for example, the bucket main body 10
A side plate fixed to one side is provided, and a side press plate 13 is arranged on the opposite side, and only the side press plate 13 is moved in the side plate approach direction to perform cargo handling in the width direction. It may be configured to compress objects. Further, the pressurizing method may be any method, for example, pressurizing the upper press plates 12, 12 by pressing down the upper press plates 12, 12 without returning the side press plates 13, 13 while applying pressure in the width direction with the side press plates 13, 13. (In this case, the width of the upper press plate needs to be set shorter than the interval between the left and right side press plates in the pressed state). In addition, the widthwise pressing drive section may be configured such that two piston rods extend and retract outward from one cylindrical section as shown in FIG. 7, or may be independent hydraulic cylinders. Also, since the guide grooves in the height direction and the guide grooves in the width direction cross each other, the stroke of the rod of the hydraulic cylinders 2, 2 in the height direction is set in the middle part, and the stroke of the rod in the width direction is set below that. It is preferable to adopt a configuration in which the strokes of the rods of the hydraulic cylinders 3, 3 are brought together so that they do not intersect. Furthermore, a hydraulic cylinder is preferable as the pressing drive unit, but this is not particularly limited in this invention. A bracket having a cylindrical portion having a threaded surface and a threaded surface that engages with the threaded surface is connected to the rear of the press plate, and the rotation of the rotating shaft (by a motor, etc.) allows the cylindrical portion to be inserted through the cylindrical portion. A structure in which the press plate is reciprocated by using a press plate, and other appropriate means are used, such as using impact force to advance for pressurization and use the repulsive force of a spring or magnetic force of an electromagnet to retreat for return. You can.

[Effect of the idea]

As described above, according to this invention, cargo with a low specific gravity that has been scooped into a bucket equipped on a vehicle can be compressed into a compact size by sequentially pressurizing it from the height and width directions with the press plate, resulting in a large volume. It is advantageous that the cargo can be handled in a compact manner, and the loading and transportation work of the cargo can be carried out efficiently. In addition, economic (investment) efficiency is improved by saving space in the vessel of the dump truck into which the cargo is loaded and at the collection site of the cargo.
