Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening material spraying device for spraying a greening material onto the ground surface such as a slope.

[0002]

2. Description of the Related Art The cut and embankment slopes begin to weather and erode immediately after the cut and embankment and tend to become unstable over time. Therefore, it is necessary to protect the slope in order to preserve the condition at the time of cutting and embankment. Typically,
A protection method called vegetation is used to artificially plant grass and trees on the slope. According to this vegetation, it is possible to prevent erosion of the slope and to green the slope.

As one of vegetation works, a spraying method for forming a layer of this greening material on the slope by spraying a greening material in which plant seeds are mixed with wood chips, soil, fertilizer or compost etc. There is that. In this spraying method, the greening material is sprayed from a pipe such as a hose and sprayed on the slope.

Further, as disclosed in Japanese Patent Laid-Open No. 11-269884, there is also a spraying method in which a greening material is sprayed on a slope using a conventional device as shown in FIG. That is, the conventional device is attached to an arm of a civil engineering machine such as a backhoe, and includes a hopper 100, a feeder 102, and a belt conveyor 104. The conventional apparatus is configured to supply a fixed amount of the green material temporarily stored in the hopper 100 onto the belt conveyor 104 by the feeder 102, and discharge the green material from the end of the belt conveyor 104 by the operation of the belt conveyor 104. There is. Then, the green material released from the belt conveyor 104 is sprayed on the slope to form a layer of the green material on the slope.

[0005]

However, in the former method of spraying the greening material using the tube, fine particles adhere to the inner wall surface of the tube, and the adhered particles grow into nodules. . This will clog the tube,
In some cases, it became difficult to spray the greening material, making it impossible to spray it. Furthermore, since the greening material is injected into the pipe, it is necessary to use finely crushed wood chips as the greening material. That is, since the crushing process is repeated many times to finely crush the wood chips, the production efficiency of the greening material is poor. For example, when a felled tree generated by cutting soil is used as a wood chip, there is a problem that it takes time before the spraying step because the crushing process of the felled tree is repeated many times.

In the method of spraying the green material using the latter device, the green material placed on the belt conveyor 104 is simply discharged from the end of the belt conveyor 104 by the operation of the belt conveyor 104. The layer of greening material formed on the slope was easy to collapse. For example, when water flows on the slope due to rain or the like, the layer of the greening material may be washed away by the water.

Therefore, an object of the present invention is to solve the above-mentioned problems. That is, the greening material can be sprayed without clogging, and the work efficiency is improved.
In addition, the layer of greening material formed on the slope is not easily broken.

[0008]

In order to solve the above problems, the invention according to claim 1 provides a first belt conveyor (for example, the first belt conveyor 340 shown in FIG. 1) and the first belt conveyor. A second belt conveyor (for example, the second belt conveyor 360 shown in FIG. 1) that is disposed so as to face the belt conveyor, and the belt surfaces of the first belt conveyor and the second belt conveyor that face each other. A distance adjusting mechanism (for example, the distance adjusting mechanism 380 shown in FIG. 2) for adjusting the distance between the belt surfaces, the greening material is sandwiched between the belt surfaces facing each other, and the belt surfaces facing each other are moved in the same direction. It is characterized by spraying a greening material.

Here, the above-mentioned greening material is a mixture containing plant seeds, for example, one obtained by mixing seeds with soil,
Wood chips (crushed wood) mixed with seeds,
For example, wood chips and soil mixed with seeds, compost mixed with seeds, and the like. A binder such as polyacrylamide, a clay mineral for the purpose of aging and water retention, water, fertilizer, etc. may be further mixed with these mixtures.

According to the first aspect of the present invention, the greening material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, and the first belt conveyor and the second belt conveyor are provided with each other. By moving the facing belt surfaces in the same direction, the green material can be sprayed from the end portion of the belt conveyor in the moving direction. By spraying this greening material, a layer of greening material can be formed on the slopes such as embankment and cut soil. Further, the injection amount and the momentum of the injection of the green material injected from the end portion in the moving direction of the belt conveyor can be adjusted by the driving speed of the first belt conveyor and the second belt conveyor.

As described above, since the greening material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, the greening material can be jetted vigorously. Therefore, the layer of the greening material can be formed on the slope by strongly pressing the greening material. That is, by strongly pressing the greening material, the layer of the greening material is compacted, and the layer of the greening material is not easily broken. In the latter conventional device having the above-mentioned belt conveyor, even if the operating speed of the belt conveyor is increased, inertial force acts on the greening material on the belt, and the greening material cannot be released vigorously. However, since the greening material is sandwiched between the two belt surfaces as in the present invention, the inertial force acting on the greening material on the belt can be suppressed, and thus the greening material can be jetted vigorously. It has become.

Further, unlike the former conventional method of spraying the greening material from the hose described above, since the greening material is sprayed by two belt conveyors, the greening material is not clogged.

Further, since the green material is sprayed by the belt conveyor, the green material can be sprayed regardless of the particle size of the green material. For example, when using a greening material in which seeds are mixed with wood chips obtained by crushing a felled tree generated by cutting soil, a greening material having a large particle size can also be sprayed, so that the labor for crushing the felled tree can be saved.
Therefore, the felled tree can be efficiently used as a material for forming a greening material.

Further, since the interval adjusting mechanism adjusts the interval between the belt surfaces of the first belt conveyor and the second belt conveyor facing each other, the injection amount of the greening material injected from the end of the belt conveyor is adjusted. it can. That is,
By adjusting the distance between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, it is possible to cope with the supply amount supplied between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor. Can be made. Then, by narrowing the interval between the belt surfaces of the first belt conveyor and the second belt conveyor facing each other, it is possible to reduce the injection amount of the green material,
By widening the interval, it is possible to increase the injection amount of the greening material. As described above, the injection amount of the green material injected from the end of the belt conveyor can be adjusted according to the amount of the green material supplied between the belt surfaces. Further, by adjusting the interval between the belt surfaces facing each other, the greening material can be sprayed regardless of the particle size.

It is desirable that the end portions of the belt surfaces of the first belt conveyor and the second belt conveyor facing each other be aligned in the moving direction. The moving speeds of the belt surfaces of the first belt conveyor and the second belt conveyor facing each other are preferably the same.

According to a second aspect of the present invention, a first belt conveyor (for example, the first belt conveyor 540 shown in FIG. 5) and a second belt conveyor (for example, shown in FIG. 5) that are opposed to each other in an overlapping state are provided. Second belt conveyor 56 shown
0), wherein the green material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, and the green material is sprayed by moving the mutually facing belt surfaces in the same direction. And
Also, the portion between the rear end side of the first belt conveyor and the second belt conveyor to which the greening material is supplied and the front end side of the first belt conveyor and the second belt conveyor on which the greening material is sprayed are bent. Alternatively, it is curved so that the spraying direction of the green material on the front end side is bent with respect to the conveying direction on the rear end side.

According to the second aspect of the present invention, the greening material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, and the first belt conveyor and the second belt conveyor are provided with each other. By moving the facing belt surfaces in the same direction, the green material can be sprayed from the end portion of the belt conveyor in the moving direction. By spraying this greening material, a layer of greening material can be formed on the slopes such as embankment and cut soil. Since the green material is sandwiched between the mutually facing surfaces of the first belt conveyor and the second belt conveyor, the green material can be jetted vigorously.
Therefore, it is possible to form a layer of a greening material that is hard to break on the slope. Further, since the greening material is sandwiched between the two belt surfaces, the greening material can be sprayed regardless of the grain size of the greening material, and the greening material does not become clogged.

Further, by bending or curving between the rear end side of the first belt conveyor and the second belt conveyor to which the greening material is supplied and the front end side of spraying the greening material, the spraying direction is bent. There is. Therefore, for example, the rear end side can be conveyed in a substantially horizontal state, and the greening material can be sprayed downward from the front end side tip.

According to a third aspect of the present invention, a first belt conveyor (for example, the first belt conveyor 540 shown in FIG. 5) and a second belt conveyor (for example, shown in FIG. 5) that are opposed to each other in an overlapping state are provided. Second belt conveyor 56 shown
0), the greening material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, and the greening material is sprayed by moving the mutually facing belt surfaces in the same direction. And the rear end side of the first belt conveyor and the second belt conveyor, to which the green material is supplied, with respect to the front end side of the first belt conveyor and the second belt conveyor, which sprays the green material. , A bending drive for bending the first belt conveyor and the second belt conveyor so that the spraying direction of the greening material can be freely changed by bending from a substantially horizontal state to a substantially right angle state or a state of a right angle or more. Means (for example, the cylinder 547, the cylinder 545, and the cylinder 546 shown in FIG. 5) are provided.

According to the third aspect of the present invention, the greening material is sandwiched between the mutually facing belt surfaces of the first belt conveyor and the second belt conveyor, and the first belt conveyor and the second belt conveyor are provided with each other. By moving the facing belt surfaces in the same direction, the green material can be sprayed from the end portion of the belt conveyor in the moving direction. By spraying this greening material, a layer of greening material can be formed on the slopes such as embankment and cut soil. Since the green material is sandwiched between the mutually facing surfaces of the first belt conveyor and the second belt conveyor, the green material can be jetted vigorously.
Therefore, it is possible to form a layer of a greening material that is hard to break on the slope. Further, since the greening material is sandwiched between the two belt surfaces, the greening material can be sprayed regardless of the grain size of the greening material, and the greening material does not become clogged.

Further, since the rear end side of the first belt conveyor and the second belt conveyor to which the green material is supplied is bent or curved by the bending driving means with respect to the front end side on which the green material is sprayed, The inclination of the front end side with respect to the rear end side can be adjusted while keeping the end side substantially horizontal. That is, the greening material can be sprayed from a direction substantially perpendicular to the slope in accordance with the slope angle of the slope while keeping the rear end side substantially horizontal. Therefore, the layer of the greening material formed on the slope can be consolidated in a stronger state, so that the layer is less likely to collapse.

Further, since the bending driving means can make the front end side substantially vertical to the rear end side,
The tip on the front end side can be directed downward with the rear end side kept substantially horizontal. Therefore, the greening material can be sprayed from above the slope while keeping the rear end side horizontal.

The first belt conveyor 340 and the second belt conveyor 360 are driven by the drive shafts 341 and 361 so that the surfaces facing each other move in the same direction. It is desirable that the moving speeds of the transport surface 343a and the transport surface 363a be substantially the same.

Drive shaft 34 of first belt conveyor 340
The storage device 310 is provided on the first side. The storage device 310 temporarily stores the greening material at the tip of the arm 231 of the backhoe 200. The storage device 310 is
It is composed of a hopper 311 and a gate 312.
The hopper 311 is a well-known hopper having an outlet at the bottom and an open top. A gate 312 is provided so as to open and close the delivery port of the hopper 311. Opening / closing drive of the gate 312 is performed by the cylinder unit 313.
Powered by. The green material is temporarily stored in the hopper 311, and the green material is sent out from the outlet by driving the opening of the gate 312.

Further, an apron feeder 320 is arranged at the outlet of the hopper 311. The apron feeder 320 is a well-known apron feeder, and the hopper 31
The greening material delivered from the first delivery port is supplied onto the transport surface 343a of the first belt conveyor 340. The apron feeder 320 quantitatively supplies the greening material. The greening material supplied by the apron feeder 320 is sandwiched between the transport surface 343a of the first belt conveyor 340 and the transport surface 363a of the second belt conveyor 360. The apron feeder 320 is driven by a hydraulic motor 321 and the backhoe 2
00 hydraulic system. The apron feeder 320 may be an electric drive type.

Next, the operation of the green material spraying apparatus 1 and the green material spraying method using the green material spraying apparatus 1 will be described. The gate 312 opens, and the apron feeder 32 is opened.
By driving 0, the greening material stored in the hopper 311 is supplied onto the transport surface 343a of the first belt conveyor 340. Transport surface 34 of first belt conveyor 340
The greening material supplied onto the 3a is driven by the hydraulic motor 346 so as to convey the surface 343a of the first belt conveyor 340.
And the transfer surface 363a of the second belt conveyor 360. The green material transported between the transport surfaces 343a and 363a is sandwiched between the transport surface 343a and the transport surface 363a by the driving of the hydraulic motor 346 and the hydraulic motor 366, and moves to the driven shaft 342. To do.
Then, the tip of the first belt conveyor 340 (the driven shaft 3
42), the greening material is sprayed toward the slope 400.
It should be noted that depending on the amount of greening material supplied from the apron feeder 320, the space adjusting mechanism 380 may be used to convey the conveying surface 343a.
It is desirable to adjust the distance between the transport surface 363a and the transport surface 363a. That is, when the amount of green material supplied is large, the interval between the transport surfaces 343a and 363a is widened, and when the amount of green material supplied is small, the interval between the transport surfaces 343a and 363a is narrowed. In addition, the amount of jetting of the greening material jetted from the tip of the first belt conveyor 340 and the momentum of the jetting are determined by the drive shaft 341.
And the rotation speed of the drive shaft 361.

As described above, the greening material can be sprayed on the slope 400 by the operation of the attachment 300. Furthermore, by moving the arm 231 of the backhoe 200, the attachment 300 is moved along the slope direction of the slope. Thereby, the greening material can be sprayed along the inclination direction of the slope 400. Also,
The swivel drive of the swivel base 220 and the crawler type traveling device 210
The attachment 300 is moved to the slope 40 by driving the vehicle.
It moves in the direction (horizontal direction) that intersects with the inclination direction of 0. Thereby, the greening material can be sprayed along the direction intersecting with the slope direction of the slope 400. In this way, by driving the backhoe 200, the greening material can be sprayed on the entire slope 400. It should be noted that when moving the arm 231, it is desirable to adjust the angle of the attachment 300 with respect to the arm 231 by the cylinder 236.
The hopper 311 can be stably held by adjusting the inclination angle of the attachment 300.

As described above, in this embodiment, the greening material jetted from the attachment 300 is sprayed onto the slope 400 to form the layer 402 of the greening material on the slope 400. Then, the transport surface 34 of the first belt conveyor 340.
Since the greening material is sandwiched between 3a and the transport surface 363a of the second belt conveyor 360, the greening material can be jetted vigorously.

If the second belt conveyor 360 is not provided, the greening material will be sprayed only by the first belt conveyor 340. In this case, even if the driving speed of the first belt conveyor 340 is increased, the green material may be scattered. However, as in the present embodiment, since the greening material is sandwiched between the first belt conveyor 340 and the second belt conveyor, the greening material does not scatter and the greening material does not scatter even if the driving speed of the belt conveyor is increased. The material can be jetted vigorously.

By vigorously jetting the greening material,
A layer 402 of greening material can be formed on the slope 400 such that the greening material is pressed. That is, since the greening material layer 402 formed on the slope 400 is compacted,
This layer 402 is hard to collapse. Furthermore, the action force for consolidating the layer 402 of the green material can be adjusted by the injection amount and the force of the injection of the green material injected from the tip of the first belt conveyor 340. That is,
The action force of consolidation can be adjusted by the rotational speeds of the drive shaft 341 and the drive shaft 361.

By the way, in the spraying method using the hose as in the above-mentioned conventional example, when the greening material in which the seed is mixed with the soil is used, the greening material may be clogged in the hose pipe. However, in the present invention, since the green material is sprayed by the first belt conveyor 340 and the second belt conveyor 360, the green material is not clogged in the hose pipe as in the above-described conventional example. Therefore, for example, a mixture obtained by mixing seeds into the local soil produced by cutting when forming the slope 400 can be used as a greening material. Therefore, it is not necessary to procure soil when manufacturing the greening material, and the construction cost can be reduced.

Further, unlike the conventional example in which the greening material is sprayed by the hose described above, in the present invention, it is not necessary to finely pulverize the wood chips which are the constituent materials of the greening material. That is,
In the present invention, since the green material is jetted by the first belt conveyor 340 and the second belt conveyor 360,
It can be sprayed regardless of the size of the greening material.
Therefore, when the mixture of seeds is used as the greening material for the wood chips obtained by crushing the felled tree generated by the cut soil when forming the slope 400, it is possible to save the labor of the crushing process of the felled tree. That is, it is not necessary to pulverize a felled tree until it becomes fine powder, and wood chips obtained by roughly pulverizing a felled tree can also be used as a material for forming a greening material. Therefore, it is possible to efficiently use the trees that can be collected locally.

Further, the conveying surface 3 by the space adjusting mechanism 380
By adjusting the distance between the 43a and the transport surface 363a, the injection amount of the green material to be injected can be adjusted according to the amount of the green material supplied from the apron feeder 320. By adjusting the distance between the transport surface 343a and the transport surface 363a, it is possible to spray the greening material regardless of the particle size.

By the way, a case of spraying a greening material on a slope having a high slope by using the greening material spraying device 1 of the present invention will be described with reference to FIG. When forming a slope on a high slope, the arm 231 of the backhoe 200
Since there is a limit to the movable range of, a plurality of slopes are formed in order from the top of the mountain. As a first step, a first slope 421 having a height within the movable range of the arm 231 of the backhoe 200 is formed from the top. When forming the first slope 421,
A step portion 431 is formed below the first slope 421 to secure a place for mounting the green material spraying device 1. In the second step, the felled tree generated when forming the first slope 421 is crushed,
Manufacture greening materials. This second step is mainly performed on site.
In the third step, the produced greening material is sprayed onto the first slope 421 using the greening material spraying device 1. Next, the second slope 422 is formed in the portion below the first slope 421, and the second step portion 432 is formed. Repeat the above,
Slopes are formed in sequence, and a greening material spraying device 1 sprays a greening material obtained by crushing a felled tree generated when each slope is formed. Green material spraying device 1 according to the present invention
In, the greening material can be sprayed regardless of the particle size of the greening material. Therefore, in the above-mentioned second step,
Coarse crushing of felled trees is sufficient, and crushing is completed in a short time. Therefore, the third step can be started immediately after the first step is completed, and the working time can be reduced. Further, in the above steps, the step portion 431 before forming the second slope 422 is wider than the step portion 431 after forming the second slope 422, so that workability in the third step is good.

Next, a second embodiment will be described with reference to FIGS. 4 and 5. The green material spraying device 2 of another example includes a backhoe 200 and an attachment 500 attached to an arm 231 of the backhoe 200, similarly to the above-described greenery material spraying device 1. The backhoe 200 has the same configuration as the above-mentioned green material spraying device 1, and the same reference numerals as those of the above-mentioned green material spraying device 1 are omitted and the description thereof is omitted.

It is arranged between 63b. The transport surface 563a of the flat belt 563 is the transport surface 543 of the flat belt 543.
It is arranged to face a. The cylinder 547 rotates about the carrier roller 544 to bend the first belt conveyor 540, and the cylinder 566 rotates about the carrier roller 564 to bend the second belt conveyor 560. That is, by the rotation of the cylinder 547, the conveying surface 543a between the driven shaft 542 and the carrier roller 544 is substantially horizontal to the conveying surface 543a between the drive shaft 541 and the carrier roller 544, or It becomes a state more than a right angle. Similarly, due to the rotation of the cylinder 566, the conveyance surface 563a between the driven shaft 562 and the carrier roller 564 is different from the conveyance surface 563a between the drive shaft 561 and the carrier roller 564.
However, it changes from a substantially horizontal state to a substantially right-angled state or a state of being more than a right-angled state.

Further, the transport surfaces 343a, 3 facing each other
63a is configured to move in the same direction and to move in the driven shaft direction from the drive shaft. As will be described later, the greening material is supplied from the storage device 310, and the greening material is conveyed from the drive shaft 541 and the drive shaft 561 side to the driven shaft 542 and the driven shaft 562 side. Therefore, in the first belt conveyor 540, the space between the drive shaft 541 and the carrier roller 544 is the rear end side to which the greening material is supplied, and the driven shaft 542.
Between the carrier roller 544 and the carrier roller 544 is the front end side on which the green material is sprayed. In the second belt conveyor 560,
The space between the drive shaft 561 and the carrier roller 564 is the rear end side to which the green material is supplied, and the space between the driven shaft 562 and the carrier roller 564 is the front end side to spray the green material.

Next, the function and effect of the green material spraying device 2 will be described. In the initial state, in the green material spraying device 2, the drive shaft 541, the carrier roller 544, and the driven shaft 542 of the first belt conveyor 540 are arranged in a substantially straight line when viewed from the side. Also, in the second belt conveyor 560, the drive shaft 541, the carrier roller 544, and the driven shaft 562 are arranged in a substantially straight line when viewed from the side. This allows
The transport surface 543a of the first belt conveyor 540 and the transport surface 563a of the second belt conveyor 560 are in a flat state.

In this state, the gate 312 is driven to open, and the apron feeder 320 is driven to drive the hopper 3
The green material stored in 11 is the first belt conveyor 5
It is supplied between the transport surface 543a of the first belt conveyor 40 and the transport surface 563a of the second belt conveyor 560. Then, the greening material is sandwiched between the drive transport surface 343a and the transport surface 363a,
It moves to the driven shaft 542. That is, similarly to the above-described greening material spraying device 1, the transport surface 343a of the first belt conveyor 540 and the transport surface 563 of the second belt conveyor 560.
Since the greening material is sandwiched between a and a, the greening material can be vigorously jetted. This makes it possible to form a layer of a greening material that is hard to collapse on the slope. Other than that, the same operational effects as those of the above-mentioned greening material spraying device 1 are achieved. In this state, the greening material can be sprayed from the side of the slope as in the first embodiment.

By the way, from the above initial state, the driven shaft 542 pivotally moves in a side view by the rotational driving of the cylinder 547. Therefore, the rear end side of the first belt conveyor 540 to which the green material is supplied and the front end side of the first belt conveyor 540 to which the green material is sprayed are bent. Similarly, the driven shaft 562 pivotally moves in a side view by the rotational driving of the cylinder 566, and follows the driven shaft 542 of the first belt conveyor 540. Therefore, the rear end side of the second belt conveyor 560 to which the greening material is supplied and the front end side of the second belt conveyor 560 onto which the greening material is sprayed are bent. Further, the cylinder 565 makes a contracting motion and the cylinder 566 makes an expanding motion. As a result, the tip of the first belt conveyor 540 (driven shaft 542) and the tip of the second belt conveyor 560 (driven shaft 562) are aligned.

Incidentally, FIG. 3 shows the first belt conveyor 54.
At 0, the carrier roller 544 and the driven shaft 542 are disposed on the rear end side between the drive shaft 541 and the carrier roller 544.
Cylinder 547 until the front end side between
Shows the state in which it has been rotationally driven and stopped. Similarly,
The cylinder 566 is rotationally driven and stopped until the front end side between the carrier roller 564 and the driven shaft 562 is substantially perpendicular to the rear end side between the drive shaft 561 and the carrier roller 564. Further, the first belt conveyor 54
The leading end of 0 and the leading end of the second belt conveyor 560 face downward. Hereinafter, for simplicity, this state is referred to as the second state.

In this second state, the front end side and the rear end side of the first belt conveyor 540 and the second belt conveyor 560 are bent so that the greening material on the front end side is greened in the conveying direction. The direction of material spray is bent. In this second state, the greening material spraying device 2 can be arranged on a step portion above the slope 400 to spray the greening material from above the slope 400. Thus, in this second state,
The greening material can be sprayed from above the slope 400 without tilting the hopper 311. Even in the second state, the green material is sandwiched between the transport surface 343a of the first belt conveyor 540 and the transport surface 563a of the second belt conveyor 560, as in the above-described green material spraying device 1. The greening material can be jetted vigorously.

As described above, in the second embodiment, the greening material can be sprayed from the side or the upper side of the slope.
Further, in the second embodiment, the state between the initial state and the second state may be set. That is, the front end side of the first belt conveyor 540 and the second end belt conveyor 560 has an obtuse angle with respect to the rear end side of the first belt conveyor 5 and the second belt conveyor 560.
40 and the second belt conveyor 560 may be curved.

In the second embodiment, the first belt conveyor 540 and the second belt conveyor 560 are variable from the initial state to the second state. As a result, the spraying direction of the greening material is variable with respect to the transport direction of the transport surface 543a and the rear end of the transport surface 563a. Therefore, the greening material can be sprayed onto the slope in a direction perpendicular to the slope in accordance with the slope of the slope. That is, the greening material can be sprayed from the direction perpendicular to the slope without tilting the hopper 311. As a result, the force of spraying the greening material on the slope becomes the strongest. Therefore, since the layer of the greening material formed on the slope is compacted, this layer is unlikely to collapse.

If only the green material is sprayed from above the slope, the driven shaft 542 and the driven shaft 562 need not be movable and may be fixed in the second state. That is, the front end sides of the first belt conveyor 540 and the second belt conveyor 560 are fixed to the rear end sides of the first belt conveyor 540 and the second belt conveyor 560 at a substantially right angle. It may be. Further, in the second embodiment, as in the first embodiment,
An interval adjusting mechanism for adjusting the interval between the transport surface 543a and the transport surface 563a may be provided. In addition, the rear end side of the first belt conveyor 540 and the second belt conveyor 560,
Even if the front end side of the first belt conveyor 540 and the second belt conveyor 560 is curved, the blowing direction of the front end greening material may be bent relative to the rear end side greening material conveying direction. good.

The greening material spraying device of the present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention. For example, the device to which the attachments 300 and 500 are attached is not limited to the backhoe 200, but may be attached to a construction work device having an arm such as a shovel device, a crane device, or a crawler crane. The attachments 300, 50 are attached to the tips of the arms of these construction work devices.
