[0001] APPARATUS FOR SPRINKLING SOIL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a soil spraying apparatus, and more particularly, to a soil spraying apparatus for spraying an embankment such as soil or sand to work on a soft soil.

Generally, since the ultra-soft ground such as tidal flats is in a slurry state, it is difficult to secure access roads for the formation of embankment layer and driving route.

Therefore, the embankment method using the conventional bulldozer was used for the embankment work of the soft ground. However, the method using the small dozer is disadvantageous in that the traveling speed is slow and the air is delayed, In the case of the soft ground, there is a problem that the ground is disturbed by the excessive running frequency of the small bulldozer as well as the middle and large type. In addition, since the load of the embankment and the load of the equipment are concentrated on the geosynthetic fiber from the one side after the geosynthetics are laid, there is a problem that the placement position of the geosynthetic fibers is deformed or pushed and the embankment layer is not uniformly formed.

In order to solve such a problem, Korean Patent Registration Nos. 0890909, 0897870, 0984732 and 1055299 and Korean Patent Laid-Open No. 2015-0114010 propose an embankment loading device using a conveyor, have.

However, in the prior art, since the embankment conveyed to the conveyor is scattered forward by using a rapidly rotating rotating body, when the conveyed embankment includes aggregate such as gravel or solid clumpy soil, There is a problem that the worker around the installation device may be injured by the debris generated by the impact, or the heavy and large aggregate may fly away and cause more destructive power, which may damage the equipment which is inadvertently remote. .

Accordingly, there is a need for a solution to solve the problems of the prior patents.

Soil spraying device

1 is a side view of a soil spray device according to an embodiment of the present invention.

As shown in FIG. 1, the soil spray device 100 according to an embodiment of the present invention includes a shake prevention wall 110 (FIG. 1) for preventing the soil from being scattered to the surroundings when the soil material falls on the conveyor, And a rotating body 132 for spraying the soil transferred by the conveyor 120 to the front of the soil spraying apparatus 100 for spraying the soil.

It is needless to say that the components shown in FIG. 1 are not essential, so that the soil spray device 100 having more or fewer components can be implemented. Hereinafter, each component will be described.

The shatterproof wall 110 is a means for preventing the gravel from being scattered to the surroundings when the gravel introduced from the outside falls onto the conveyor 120. The shatterproof wall 110 may be formed in a shape that surrounds all sides or on the left and right sides A wall having a predetermined thickness may have a surrounding shape.

The soil gravel injected from the upper part falls directly to the conveyor 120, but the gravel falling down is scattered around due to the impact with the conveyor 120. The shatterproof wall 110 prevents such scattering, and can guide the scattered gravel around the conveyor 120 again due to the fall.

The conveyor 120 is for conveying the soil supplied from the outside, and the type of the conveyor is not particularly limited. However, it is preferable that the conveyor 120 is a belt conveyor in terms of graininess of the material to be conveyed.

At this time, it is preferable that one end of the conveyor 120 is installed corresponding to the installation position of the scattering prevention wall 110.

The belt of the conveyor 120 can be supported by the conveyor pulley 122 and the conveyor guide roller 123 so as to be able to rotate while being tightened by a tension greater than a predetermined size. The conveyor belt caught by the conveyor pulley 122 and the conveyor guide rollers 123 is conveyed to the conveyor pulley 122 through the conveyor drive chain 124 by the driving force generated by the conveyor drive device 125, And is rotated by the rotation of the conveyor pulley 122.

Here, it is preferable that the conveyor pulley 122 for rotating the belt of the conveyor 120 is located on the side opposite to the side of the scattering prevention wall 110, that is, on the side where the soil is sprayed. This is because the driving method of the conveyor for conveying the gravel is adopted as the front wheel type, so that the loss of the conveyor driving force can be relatively reduced as compared with the case using the rear wheel method.

The conveyor drive device 125 that provides the driving force to rotate the conveyor pulley 122 is preferably located at the other end of the conveyor 120, i.e., on the opposite side of the shatterproof wall 110, The drive device supports 126a and 126b may be erected on the other end of the conveyor frame 121 that supports the conveyor 120 so that the conveyor 125 can be seated.

On the other hand, as described above, the conveyor frame 121 can be provided with the drive device support portions 126a and 126b at the other end thereof, and a plurality of shatterproof Wall supports 111 and 112 may be provided.

Further, at one end of the conveyor frame 121, the conveyor frame 121 may have a conveyor frame rotation shaft 142 so as to form a ground surface, a horizontal surface, or an inclined surface. The conveyor frame 121 may be provided with the hydraulic cylinder 141 toward the conveyor frame 121 on one side of the base body 140 rotatably mounted on the undercarriage on which the wheels of the endless track 170 are installed, The conveyor frame 121 can be rotated about the frame rotation shaft 142 by the reciprocating motion of the hydraulic cylinder 141. [ The conveyor frame 121, which is rotatable about the frame rotation shaft 142, can be adjusted to have a predetermined angle with the ground surface, thereby controlling the spreading distance or the spraying range of the gravel.

The other end of the conveyor 120, that is, the front end of the soil spray device 100, is provided with a rotating body 132 for scattering the soil transferred by the conveyor 120.

At this time, the rotating body 132 is positioned in front of the conveyor 120 so that the gravel conveyed by the conveyor 120 does not fall out through the gap formed between the conveyor 120 and the rotating body 132, The rotating body 132 is disposed at a front lower portion of the conveyor 120 and the end of the conveyor 120 and the blades of the rotating body 132 are arranged to overlap a predetermined portion, It is preferable to spray the dropped soil at the end portion of the sprayer in the forward direction.

Here, a detailed description of the rotating body 132 will be described later.

The soil spraying apparatus 100 further includes a rotating body driving device 131 for generating a driving force for driving the rotating body 132 and a driving force generating device for generating driving force generated by the rotating body driving device 131, And a rotating body driving belt 133 for transmitting the rotating body driving force.

Reference numeral 150 denotes a generator, and the generator 150 can transmit the electric energy generated by the driving to various driving devices installed in the soil spraying apparatus 100.

Rotating body

The rotating body 132 is interposed between the two arms extending forward from the conveyor frame 121 so as to traverse the rotating shaft 1329 so as to be rotatable about the rotating shaft 1329 with a cylindrical body The whole body 132 can rotate.

FIG. 2 is a perspective view of a rotating body according to an embodiment of the present invention, FIG. 3 is a perspective view of a rotating body according to another embodiment of the present invention, FIG. 4 is a view And FIG. 5 is a view illustrating an operation process of the wing receiver of FIG.

2, the rotating body 132 includes a cylindrical body, at least one brush base 1321a, 1321b radially installed on the outer circumferential surface of the body, and at least one brush base 1321a , 1321b.

The brush bases 1321a and 1321b are formed in a substantially plate shape so that the width of the brush bases 1321a and 1321b is formed along the longitudinal direction of the rotating body 132, . Here, the brush bases 1321a and 1321b may be made of steel, but are not particularly limited.

Brushes 1322a and 1322b are bound to the outer ends of the brush bases 1321a and 1321b in the radial direction of the cylindrical rotating body. The brushes 1322a and 1322b fixed to the outer ends of the brush bases 1321a and 1321b may be provided with a plurality of brush wire strands in a single row or a double row, Is not particularly limited.

The brush wire strand may be made of iron or plastic, and may be a linear straightened or repeatedly curved wave shape. In the present invention, the material, shape, length, etc. of the brush wire strand are not particularly limited.

However, it is preferable that the brush wire strand has a sufficient rigidity or elasticity enough to scatter a small lightweight soil by forward rotation of the rotating body 132 due to the rotation of the rotating body 132.

According to the prior art, most of the wings of the rotating body 132 are made of iron, so that heavy, large gravel or loosely adhered gravels are easily damaged by impact with the wing end of the rotating body 132, , And the fragments are scattered over a wide range around the soil spray device.

However, according to the present invention, the blade end portion of the rotating body 132 is composed of the brushes 1322a and 1322b, and the heavy and large gravel or the loosely adhered gravels enter the inside of the rotating body 132 through the brushes 1322a and 1322b The brush bases 1321a and 1321b made of steel and the fragments generated by the impact are generated mainly inside the rotating body 132 and the range of fragments is reduced.

Since the brushes 1322a and 1322b at the blade end portions of the rotating body 132 have a buffering effect against the entry of the aggregate when the heavy and large gravel or the loosely adhered gravel enter the inside, It is possible to reduce wear and tear of the blades of the rotating body 132.

According to another embodiment of the present invention, the distal ends of the brushes 1322a and 1322b are preferably curved in one direction in order to reduce the extent of debris and prevent scattering of debris. The fragments generated in the inside of the rotating body 132, that is, in the vicinity of the brush bases 1321a and 1321b are not scattered to the outside of the rotating body 132 but are bent at the ends of the brushes 1322a and 1322b, Can be prevented from being scattered.

According to another embodiment of the present invention, the rotating body 132 includes at least one wing receptors 1323a and 1323b radially installed on the outer peripheral surface of the body, and at least one wing receptors 1323a, (Components corresponding to the reference numerals 1321a and 1321b) inserted into the ends of the brush bases 1325a 'and 1323b. Here, the brush base 1325a 'may be bound to brushes 1325a and 1325b on the outer side as described above.

The wing receivers 1323a and 1323b are formed in a substantially box-like box shape so that the width of the wing receptors 1323a and 1323b is formed along the longitudinal direction of the rotating body 132 Radially.

At this time, an outflow hole (not shown) is formed on the outer side of the wing receptacles 1323a and 1323b so that the plate-shaped brush base 1325a 'inserted into the entry / exit hole can be inserted / removed through the access hole.

The brush base 1325a 'is coupled to the inside of the wing receptors 1321a and 1321b by the elastic body 1327 so that the brush base installed in the radial direction is connected to the brush base 1325a' May be drawn or drawn from the wing receptors 1323a and 1323b (see FIGS. 4 and 5).

The brush base 1325a 'fastened by the elastic body 1327 is subjected to centrifugal force in the radial direction due to the rotation of the rotating body 132 at a high speed and the centrifugal force acts on the elastic body 1327 by the weight of the brush and brush base 1325a' The rotating body 132 rotating at a low speed is contracted by the elastic force of the elastic body 1327. [ That is, the elastic body 1327 is stretched or contracted due to the balance between the elastic force of the elastic body 1327 and the centrifugal force of the rotary body 132, so that the brush base 1325a ' Or the like.

Therefore, the rotating body 132 having the wings extended from the wing receptors 1323a and 1323b by the brush base 1325a 'in accordance with the rotating speed of the rotating body 132 can scatter the introduced soil particles to a large distance Conversely, the brush body 1325a 'is drawn into the wing receptors 1323a and 1323b and the rotating body 132 having the shortened wings can scatter the introduced gravel particles to a close distance.

As described above, the brush base 1325a 'can be coupled with the inside of the wing receptors 1323a and 1323b and the elastic body 1327. [ Specifically, as shown in Fig. 4, the brush bases 1321a and 1321b inserted into the wing receptors 1323a and 1323b include at least one brush base 1321a and 1321b formed on one end of the wing receptors 1323a and 1323b, And the wing receivers 1323a and 1323b may include at least one second elastic body guide portion 1326 on the inner side of the first elastic body guide portion 1328 opposite to the first elastic body guide portion 1328 Both ends of the elastic body 1327 can be fixedly coupled to the first elastic body guide portion 1328 and the second elastic body guide portion 1326, respectively.

The wing receptors 1323a and 1323b further include sealing members 1323a and 1323b around the entrance and exit through which the brush base 1325a 'is taken in and out so that the gap between the entrance and exit holes and the brush bases 1321a and 1321b It can be shielded.

The sealing members 1323a and 1323b are formed in such a manner that the grains in the form of particles are prevented from flowing into the wing receptors 1323a and 1323b inside the entrance and exit holes of the wing receptors 1323a and 1323b, 1321b may be densely packed so as to be able to go in and out.

According to yet another embodiment, the sealing members 1323a and 1323b may be formed of a shielding film 1324a, 1324b, or 1324a, 1324b. The blocking films 1324a and 1324b to which the both ends of the entrance and exit holes and the brush base 1325a 'are fastened and fixed are formed in such a manner that the blocking films 1324a and 1324b of the stretchable material are stretched at the same time as the brush base 1325a' The first and second wings 1322a and 1322b are shielded from the outside and the flat appearance is maintained so that the particle type gravel can be scattered from the soil spraying apparatus 100 without forming any obstacle on the surface of the wings, , And sprayed.
