Description

[Detailed Description of the Invention] The present invention relates to a sending device used for backfilling excavated soil into holes and trenches during conduit work such as gas pipes and water pipes.

Conventionally, for example, when burying a gas pipe, it is done according to the procedure shown in FIGS. 5 to 9.

In other words, a trench B with a width of 20 to 30 cm and a depth of about 2 m is created on a road or other flat area A using an excavator such as a trencher.
, and install gas pipe C at the bottom of trench B. Next, fill trench B with the excavated soil on the side of the trench by about 1 m, and pat it down with a tamper. Then, fill in all of the remaining excavated soil. A method of compacting it again in Tampa is being used.

However, in the past, this backfilling work was performed manually or by civil engineering machines such as bulldozers, but in the work process, the depth of the trench was approximately half (1 m ± 20 m).
cm) is used first, so it can be done evenly to a certain extent by hand, but the disadvantage is that it takes time, but labor savings can be expected if civil engineering machines such as bulldozers are used. There was a problem that it was not possible to backfill continuously and uniformly.

This invention was devised to solve the above-mentioned problems, and its main purpose is, for example, to transport excavated soil placed on the side of a trench into the trench in appropriate amounts so that the depth is uniform. To provide a sender device capable of continuously backfilling.

Another object of the present invention is to provide a screw in a blade body having a side plate, and also to provide a rotatable wing at the tip of the side plate, and cut the tip of the wing into the excavated soil placed on the side of the ditch to cut the required amount. To provide a sending device which divides the paper into pieces, presses them side by side with a screw, breaks them down, and conveys them into a groove in appropriate amounts.

Still another object of the present invention is to provide the rotatable wings at the tips of the left and right side plates of the blade body, and to twist the screws in the opposite direction with the border at approximately the center, so that there is excavated soil on both sides of the groove. To provide a sending device which is capable of transporting objects into a groove even when the object is in use.

Another object of the present invention is to provide a sending device using wings provided on both side plates and screws twisted in only one direction.

Still another object of the present invention is to provide a sending device that uses a wing that is pivotally mounted on only one side plate and a screw that is twisted in only one direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be explained below based on the drawings showing embodiments of the present invention.

The sending device 1 of the present invention is used by being attached to a working vehicle 100 such as a tractor shovel or a shovel loader, and includes a mounting body 2 attached to the tip of a boom 101 of the vehicle 100, and left and right side plates 3, 3. and a blade body 5 having at least a rear plate 4 and fixed to the front surface of the mounting body 2, a screw 6 provided between the side plates 3 and 3 of the blade body 5, and a drive mechanism 7 for rotating the screw 6. The main parts of the blade body 5 include a wing 8 rotatably mounted on the tip of the side plate 3 of the blade body 5, and a fluid pressure cylinder 9 for operating the wing 8.

As described above, the blade body 5 includes the left and right side plates 3.3 and the rear plate 4, and the lower end of the rear plate 4 has a cutting edge 10.
is installed to function as a soil removal board.

The screw 6 has a spiral plate 12 threaded around the outer periphery of a shaft 11. Both ends of the shaft 11 are received by bearings 13, 13 provided on the side plates 3, 3, and a drive mechanism 7 is mounted at one end. It is connected.

In the first embodiment shown in FIGS. 1 and 2, the spiral plates 1 are twisted to the right and twisted to the left, respectively, with approximately the center as the boundary.
A screw 6 having screws 2 a and 12 b screwed onto the shaft 11 is employed.

The drive mechanism 7 for rotating the screw 6 can be of various types, but in this embodiment, a case is illustrated in which it is composed of a hydraulic motor 14, an appropriate sprocket (15, 16), and a chain 17 extending between them. ing.

The base end of the wing 8 is rotatably provided at the tip of the side plate 3 by a vertical shaft 18, and a fluid pressure cylinder 9 operates the wing 8.
are the bracket 19 protruding from the back of the wing 8 and the side plate 3.
The wing 8 is interposed between other brackets 20 extending outside the wing 8, and by expanding and contracting the same hydraulic cylinder 9, the wing 8 can pivot by a required angle.

Incidentally, as shown in FIG. 2, a skid shoe 21 is provided at the lower part of the mounting body 2, and this can also be provided on the blade body 5.

Since the present invention has such a configuration, first of all, please refer to Figures 1 and 2.
The operation and usage of the first embodiment shown in the figure will be explained.

As shown in the figures, the device 1 is grounded, and the wings are set at an angle of 8° 8 with respect to the excavated soil D loaded on both sides of the trench B.

In this case, the hydraulic cylinders 9, 9 are expanded and contracted to rotate the wings 8, 8 through a required angle.

Next, the drive mechanism 7 is operated to rotate the screw 6.

The direction of rotation of the screw 6 is set so that the excavated soil is sent to the groove B side.

It is assumed that the groove B is located approximately at the center of the device 1 as shown in FIG.

When the device 1 is moved forward together with the work vehicle 100 at an appropriate speed in this state, the excavated soil loaded on both sides of the trench B,
D is first divided at the tips of the wings 8, 8, and only the excavated soil inside is sent to both ends of the screw 6 through the wings 8, 8 and the side plates 3, 3, and then the screw 6
The person is conveyed to the groove B side while being crushed by the spiral plates 12a and 12b, and falls into the groove B.

In addition, since a rear plate 4 is provided behind the screw 6 and a cutting edge 10 is provided at the lower end of the rear plate 4, there is no trailing of the excavated soil, and the excavated soil is evenly backfilled in the trench and the ground in the vicinity is flat. The ground will be leveled.

The conveyance amount on the excavation can be easily adjusted by varying the angular position of the wings 8, 8 and the rotational speed of the screw 6.

This is particularly effective when first backfilling groove B to half the depth shown in FIG. 8, and can be done uniformly and continuously.

Incidentally, the backfilling depth shown in FIG. 8 must be maintained at 1 m±20 cm, and from this point of view as well, work efficiency can be improved.

The first embodiment shown in FIGS. 1 and 2 has wings 8, 8 operated by fluid pressure cylinders 9, 9 on both the left and right side plates 3, 3, respectively, and the screw 6 is located approximately in the center. A reverse twist type was adopted with the boundary between trenches B and D, which was excavated on both sides of trench B.
As in the second embodiment shown in the figure, the screw 6 is twisted in one direction, and for example, when excavated soil is on one side of the groove B, one wing 8 is used and the screw 6 is rotated in the normal direction, and the screw 6 is rotated in the opposite direction. If an excavation top is placed on the other side, the other wing 8 can be used to reverse the screw 6.

It is also possible to provide the wing 8 only on one side plate 3, as in the third embodiment shown in FIG. 4.

As described above, when the present invention is used for burying gas pipes, water pipes, etc., it is possible to uniformly backfill the excavated soil on the side of the ditch in a short period of time.

Therefore, the work that meets the purpose of construction can be carried out more easily than by human labor or civil engineering machines such as bulldozers, and it brings about various effects such as greatly improving work efficiency and saving labor.
