Description

[Detailed description of the device] This device is an improved device that can be attached to the end of the arm of a hydraulic excavator, etc., and used for a wide range of civil engineering work such as excavation, earth and sand transfer, leveling, slope formation, etc. This is related to the structure of the packet.

The earthwork packets that have been developed and put into practical use come in a variety of shapes and structures, and it is now possible to select and use grooved packets depending on the type of civil engineering work. ing.

However, among these various packets, there are very few that take into account their versatility for various types of civil engineering work, and therefore, during actual civil engineering work, packets that are originally only effective for a certain type of use are often used. , because the replacement work is complicated, or because various packets are not available, the situation is such that they are simply forced into general use.

Furthermore, all of these conventional packets had little consideration given to the adhesion of dirt and sand, and their inner surfaces were all smooth flat surfaces, or at most had only a slightly curved surface. Therefore, during excavation, transporting earth and sand, leveling the ground, forming slopes, etc., during the frequent movement of earth and sand into and out of these packets, a large amount of earth and sand adheres to the inner surface of the packet, which not only reduces the volume of the packet, but also This also resulted in a reduction in excavation capacity.

In addition, the same packet can be used with the opening at the bottom and the back plate at the top, so that the bottom plate and the back plate can be used for compaction work in which the outer surface of the bottom plate is used to press excavated trenches or slopes. Because it is constructed in one piece, soil particles accumulate on the back plate and gradually stick to the outer surface of the bottom plate, which not only makes it impossible to finish the main sand surface neatly, but also impairs its soil consolidation ability. It also caused a decline in the

Since dirt and sand adhere firmly to both the inner and outer surfaces of the packet, it is extremely inconvenient to clean the packet.

This invention has been researched and developed in order to cope with such a conventional situation, and its details will be explained below with reference to the attached drawings based on a typical embodiment of this invention.

As can be understood from the overall perspective view of FIG. 1, the general-purpose packet of this invention has a bottom plate 1. Side panels 2, 2 and ceiling panel 3
It has a front and rear open type packet main body 4 consisting of
Rear cover plates 6, 6 are provided near the opening of the rear opening 5, and are swingable only on the front side of the packet main body 4, and at least the bottom plate 1 and both side plates 2, 2 in the front opening 7 are provided. At the edge portion and the transverse portion of the bottom plate 1, there are rib members 8°8 having a chevron-shaped cross section with the top facing inward of the packet body 4.
..., 9, 9 are stretched, and each inner corner formed between each plate 1, 2.3 may be chamfered. Fillet rib members 10, 10, .

The above-mentioned packet main body 4 has an open opening in the front and rear directions that has a clearance angle of θ9 in the vertical direction of the side plates 2, 2. θ9, it is formed into an inverted trapezoidal shape, and the side plates 2°2 have a lateral clearance angle θ8. θ8 and the relief angle θ2 in the depth direction of the bottom plate 1, the bottom plate 1 is formed so as to be gradually reduced from the front opening 7 to the rear opening 5, and a reinforcing plate 11 is erected at the central longitudinal section. , Fillet rib material 10 is also provided at both corner portions formed by the reinforcing plate 11 and the bottom plate 1.
10 is stretched.

The bottom plate 1 is curved in an ascending shape with a relief angle θ2 in the depth direction of the packet body 4 (in addition to the illustrated example, there is also a case where only the rear portion is curved following the front straight portion.

), and the lateral relief angle θ of both side plates 2, 2 is
8. A substantially triangular horizontal blade 12,1 protruding outward from θ.
2 is formed.

Although not shown in the drawings, if the bottom plate 1 is made to have an appropriate clearance angle in the left and right directions in addition to the clearance angle θ2 in the depth direction, it will be possible to form a flat surface during leveling work. becomes even easier.

The ceiling plate 3 is provided with a body 13 on its outer surface for attaching the packet body 4 to an arm A of a hydraulic excavator or the like.

In this installation, the body 13 consists of a disc-shaped receiving plate 14 welded to the ceiling plate 3 and a disc-shaped connecting plate 16 having shaft rods 15, 15 for fitting onto the arm A. After fitting the central hole 18 formed in the connecting plate 16 to the central shaft 17 provided upright on the plate 14, the receiver screws the seat nut 21 into place.
After determining the angle of the packet body 4 with respect to the connecting plate 16 using the central axis 17 as a support, insert bolts into several through holes drilled near the circumference of the drawing plate 14 and 16 and tighten nuts each time. The attachment of the packet main body 4 to the arm A is such that the angle can be freely adjusted within a range that is an integral multiple of the distance between the through holes.

(This angle adjustment is useful when excavating a side ditch in the condition shown in Figure 4.

) In the figure, symbol a indicates the chevron-shaped cross section of the rib material 8, b indicates the chevron-shaped cross-section side of the fillet rib material 10, and 19.20 indicates the front and rear stoppers for the rear cover plate 6. In particular, the rear stopper 20 is intended to prevent the rear cover plate 6 from swinging to the outside of the packet body 4 so as not to interfere with normal excavation work.

In the packet of this invention, during excavation work, the rib members 8, 8, .
, side plate 2. Since it is stored in the packet in a floating state without being directly pressed against each inner plane part of the ceiling plate 3, it becomes difficult for dirt and sand to adhere to the inside of the packet, especially on the bottom plate 1, which is hard to adhere to. , rib material 9 on the bottom plate 1,
9, the state becomes even more difficult to adhere to.

Moreover, the stored earth and sand is most likely to adhere to and solidify at each corner of the packet, and chamfered fillet rib material 10°10... is attached to each corner. This makes it even more difficult to stick.

In addition, as shown in Fig. 5, with the front opening 7 at the bottom and the rear opening 5 at the top, the outer surface of the bottom plate 1 is used to push the slope upward along the slope of the excavation trench or bank. When attempting to perform soil consolidation or slope formation work by stroking, the rear end of the bottom plate 1 (the left end of the cross section of the bottom plate 1 in the figure) digs into the slope, and the sand on the slope that has been scraped away. is placed on the outer surface of the rear cover plate 6, and the rear cover plate 6 is rotated so as to be pushed up toward the inside of the packet body 4,
The earth and sand is extracted from the rear opening 5 between the cover plate 6 that has rotated forward and the inner surface of the bottom plate 1 to the front opening 7 along the inner surface of the bottom plate 1, and is scraped off. The sand on the surface accumulates and adheres to the outer surface of the rear cover plate 6, and even promotes adhesion to the outer surface of the rear end of the bottom plate 1, which impedes the work of scraping off the sand. Completely eliminate the harmful effects of the past.

Although this effect was not shown, the front opening 7 of the packet main body 4 is placed at the top, the rear opening 5 is placed at the bottom, and the rear end of the bottom plate 1 is moved from the top to the bottom while digging into the slope. The same effect is achieved in the embodiment in which the sand on the slope that has been scraped off is removed by rotating the rear lid cup 6 so that its outer surface is visible and pushing it up toward the inside of the packet body 4. A space for passage of earth and sand is formed that allows passage from the rear opening 5 to the front opening 7.

However, in this embodiment, unlike the illustrated embodiment above,
The movement of the earth and sand is such that it passes from below to above relative to the packet body 4.

Therefore, the earth and sand scraped off not only on the inner side of the packet body 4 but also on the outer side can be carried out with almost no stagnation. Therefore, slope preparation work such as slope formation work can be carried out continuously and accurately. It is something that can be done.

If the bottom plate 1 is provided with horizontal blades 12, 12 on both sides as in the illustrated embodiment, the surrounding earth and sand to be excavated next will be simultaneously destroyed while excavating.
In addition to making the excavation work easier, if the outer surface of the bottom plate 1 is formed to be a slightly outwardly curved surface,
When applying pressure using the outer surface and leveling the ground, if the bottom plate 1 is simply formed on a flat surface, the center portion of the bottom plate 1 will be curved inside the packet body 4, resulting in insufficient filling. Although it is not possible to perform pressure or accurate leveling work, it is possible to reliably perform the work as expected.

In addition, when digging a ditch on one side of the excavator, instead of attaching the packet via the auxiliary arm as in the conventional case, the present invention allows the arm A to be oriented diagonally toward the ditch. Attach the packet to the receiving plate 1 of the body 13
4 and the connecting plate 16 so that it is parallel to the side ditch to be excavated, and after fastening and fixing with bolts and nuts, from then on, all you have to do is perform the same operations as normal excavation work. It turns out.

In the case of this excavation, it is impossible for the packet to excavate in the direction of the groove (direction of the front opening 7 of the packet) due to the mechanism of the hydraulic excavator vehicle M. The packet body 4 is excavated and rotated in a diagonal direction with respect to the direction of the front opening 7 of the packet body 4, but the packet main body 4 has a respective relief angle θ8. θ9. Since it has θ2, the bottom plate 1
And the earth pressure resistance applied to the side plate 2 during excavation is reduced,
The excavation rotation can be carried out without difficulty, and the upper surface of the trench chamber is finished in a gentle slope shape as if the packet had been excavated and rotated in the direction of the trench.

As mentioned above, the general-purpose packet of this invention can be used on its own for excavation and soil transfer during various civil engineering works.

It can be used for a wide variety of purposes such as leveling the ground, compacting the ground, and forming slopes.Therefore, there is no need to select and replace packets for each work purpose, and the packets are especially suitable for digging ditches. When adopted as a general-purpose device, this invention can be used at the tip of arm A that is standard equipment on hydraulic excavators M such as tractor excavators (there is no need to separately combine a conventional auxiliary arm for digging ditches). All that is required is to adjust the attachment angle of the packet to a predetermined angle with respect to the arm axis, and the subsequent operation of the packet is no different from normal excavation operations. This method not only does not have the disadvantages of applying an excessive external force to the arm itself or reducing the force transmitted to the packet, which hinders excavation ability, as with the conventional method that uses a combination of auxiliary arms, but it also reduces the It is capable of producing remarkable effects such as slope formation, ground leveling, and soil compaction work that can be carried out in an integrated manner.

In addition, during these work processes, the adhesion of dirt and sand to the inner surface of the packet is effectively prevented by forming each rib, which increases the efficiency of each work and has the additional effect of increasing the strength of the packet body. Furthermore, it also has the advantage of making it extremely easy to clean the packet after the work is completed.

Furthermore, if necessary, each of the above-mentioned effects can be further enhanced by forming the side blades 12, 12 or making the bottom plate curved as shown in the embodiment. According to the general-purpose packet of this invention, it is possible to exhibit a number of excellent functions.
