The present invention relates to a dump truck-mounted snow removing device, more specifically, the sand and calcium chloride spreading device made to spray sand and calcium chloride, which are sprayed for snow removal, between the front head of the dump truck and the loading box. It is invented to be located in the space of the fixed to the loading box to increase the snow removal effect of the snow removal vehicle and to ensure the safety of the snow removal vehicle.

Currently, snow removal vehicles for winter snowfall are arranged in each administrative area, and most of these types are partially remodeled with existing cargo-loaded vehicles, and the snow plow is attached to the front to clear the road after sweeping the snow to one side. The sand or calcium chloride loaded is sprayed to the rear to prevent the road from slipping and to allow the vehicle to pass through.

However, vehicles with this configuration are often in extreme road conditions due to the lack of additional aids or safety devices in addition to these two main functions, such as snow snow removal and grading, and sand spraying. Or excessive snow removal may cause serious problems in the safety of the snow removal vehicle itself.

For example, there are often cases where the slope of the snow road is so severe that the snow removal vehicle cannot enter or the fall accident occurs due to the slip of the vehicle itself.

On the other hand, compared with the snowy foreign countries, Korea has little snowfall in the year, so the spread rate of snowplows is rather inadequate, and the snow removal capacity of each snowplow in each administrative area is not so high.

In addition, the places where special vehicles mainly manufactured for the purpose of snow removal have been distributed, and they are mainly used for snow removal by modifying and supplementing existing dump trucks, and rely mainly on manpower for small snow removal operations. to be.

On the other hand, snow removal equipment can be divided into independent snow removal equipment and auxiliary equipment. Independent snow removal equipment has its own power and can perform snow removal without the help of other devices, such as a dump truck, a multipurpose snow removal vehicle, a grader, Ancillary equipment does not have power and is attached to independent equipment according to each snow removal purpose, and includes snow blade, sand spreader, calcium chloride spreader, blower, road surface crusher and snow cutter.

Among them, dump truck is the main equipment of snow removing equipment in Korea, and it is usually used as a construction vehicle, but in winter it is used as a snow removing vehicle. 8 ton and 15 ton dump trucks are mainly used. The trend is changing.

Such a dump truck is attached to a snow blade or sand and chloride spreader can be used for multi-purpose, such as extrusion or spraying operations depending on the purpose of snow removal.

At this time, the work load generated by the snow load during the pushing operation by attaching the snow removal blade to the dump truck is generated in the front part of the vehicle, but the driving is transmitted to the snow removal blade part of the front which is loaded by the rear wheel drive and the power. The space at the rear of the vehicle prevents the transmission of great force during operation.

Therefore, the dump truck is a snow removal equipment that can be used when the amount of snow is relatively small than when a large load is applied to a large load.

The speed of snow removal by attaching snow blades to such dump truck is about 25 ~ 35km / h (based on 15 ton dump truck) on the flat ground, and the sand truck or calcium chloride aqueous sprayer is mounted on the dump truck to remove snow. The speed at which it is carried out is about 15-20 km / h on the plain.

In addition, the multi-purpose snow removal vehicle is a snow removal vehicle that can be equipped with a variety of additional equipment such as snow blades, spreaders, brushes and blowers to perform the snow-related work for multi-purpose, such equipment is usually driven by four-wheel drive snow removal work It can be used when you need great power, and the speed of snow removal is faster than other equipment, and in addition to snow removal, it is equipped with other related auxiliary equipment for roadside mowing, cleaning of guide rails or signs, and collecting road sand. It is utilized.

On the other hand, the most widely used type of snow removal vehicle in Korea is a type of 15-ton dump truck, as described above. The main device is attached to the front of the vehicle, and the angle of the snow blade, calcium chloride, It is composed of a snow removing box such as sand, a loading device and a spreading device.

As mentioned above, such a vehicle is less effective due to structural problems that do not transmit great force during operation, and because of the driving mechanism in the rear wheel, the road surface is severely frozen or snow removal work on a severe slope. In the case of wheels, the wheel may slip and may not be able to move forward, and in severe cases, there may be a fall accident of the snowplow itself.

The easiest way to reduce the problem of slip and fall accidents is to wind the snow chains on the wheels of the vehicle, or to install calcium chloride or sand with manpower, but these methods are extremely effective. It is inadequate, takes a lot of work such as installation and dismantling, and in most cases requires additional personnel other than the driver.

Therefore, it is necessary to maximize snow removal effects and supplement snow removal equipment in consideration of safety of snow removal vehicles and drivers during snow removal work.

The present invention has been made in order to solve such a conventional problem, the sand and calcium chloride spreading device for spraying a snow removing agent (sand or calcium chloride) to be sprayed for snow removal between the front of the dump truck and the loading box. It is located in the space and detachably fixed to the loading box so that it does not interfere with the cargo loaded into the loading box of the dump truck at all, eliminating the waste of time and labor cost required for installing and dismantling the spreading device. It is an object of the present invention to provide a dump truck-mounted snowplow spreading device that can increase snow removal effect without affecting the driving of a dump vehicle having a rear wheel driving device at all and assure safety of the snow removing vehicle itself.

Referring to the effect of the dump truck mounted snowplow spreading device of the present invention configured as described above are as follows.

First, the apparatus of the present invention comprises a snow removing device (sand or calcium chloride) spreading device composed of a main body 3, a snow removing and discharging and spreading device 4, and a motor 5, as shown in FIG. ) And the main body 3 is detachably installed in the storage box 2 by means of the fixing means 6, and is located in the space formed between the storage box 2) and the loading box 2.

In this way, when the snow removing device comprising the main body 3, the snow removing and discharging and the spraying opening 4, and the motor 5 is installed on the front surface of the dump truck 2 in a fixed or detachable manner, Since the spraying device itself does not interfere with the operation of the truck, including the cargo loaded in the dump truck's loading box, the dump truck can be driven with the snow removing device installed. Waste of time and labor required for dismantling, etc. can be eliminated, and the snow removal effect of the dump vehicle equipped with the rear wheel drive device is not impeded during snow removal work, and the snow removal effect can be enhanced and the safety of the snow removal vehicle itself is secured. You can do it.

At this time, the main body 3 which is directly fixed or detachably fixed through the fixing means 6 to the front portion of the stacking box 2 is an upper surface using an iron plate having a predetermined thickness (for example 5t) The shape of the opening is bent into a substantially rectangular shape, the longitudinal section is bent to form a hopper shape in the rear of the front and rear surfaces inclined inward, the bottom surface has an arc shape and the sand or calcium chloride, which is a snow removal agent on both sides can be discharged It will have a form in which the snow removing agent discharge hole 31 is punched out.

In the above, the front plate of the main body 3, which is installed to be fixed or detachably directly to the front part of the loading box 2, may be all installed like the rear plate, and if necessary, the front part of the loading box 2 The material cost may be reduced by removing the part contacting with and fixing the remaining part directly to the front part of the loading box (2).

In addition, as the fixing means 6 for fixing the main body 3 to the loading box 2, a fastener having a predetermined shape including a bolt and a nut may be provided. In this case, the device of the present invention can be detachably installed on the front surface of the dump truck's loading box (2), and if necessary, a welding method is adopted as the fixing means (6). It can also be directly welded to the front of the).

On the other hand, the snow removal and discharging and the spraying port (4) axially rotatable at the bottom in the main body (3) is wound in opposite directions on both sides around the intermediate point of the rotary shaft (41) A screw 42 having a shape is formed over a predetermined section (that is, from an intermediate point to both sides from the middle point to the start of the snow removal outlet 31), and above the snow removal outlet 31 of the main body 3. It has a configuration in which a snow removal agent propeller 43 is installed over a predetermined period at both ends located in the portion.

In addition, the motor (5) has a shaft whose shape is connected to one side of the snow removal and discharging and the spray port 4 and is fixedly installed on one side of the lower part of the main body (3) to the inside of the main body (3) Generates the power required to spray sand or calcium chloride, which is loaded on snow, to transport and discharge the snow, and the spraying port 4 is rotated to allow the snow to be sprayed.

That is, when the motor 5 is driven while loading a snow removal agent such as sand or calcium chloride in the main body 3 and driving a dump truck, the shaft and one end of the motor 5 are coupled to each other. Since the snow removing and discharging and the spraying opening 4 rotate in response to the rotational force of the motor, the snow removing agent in the main body 3 is moved from both sides at the intermediate point of the rotation axis 41 of the snow removing and discharging and the spraying opening 4. By the two screws 42 having the shape wound in the opposite direction to each other by being pushed to both sides of the main body 3 as well as the snow removal agent thus moved to both ends of the snow removal and discharging and spraying port (4) The installed propeller 43 is automatically sprayed onto the road through the snow removal agent discharge hole 31 perforated on both sides of the bottom surface of the main body 3.

At this time, when the snow removal agent discharge hole 31 drilled on both sides of the bottom surface of the main body 3 is left as it is, the snow removal and rotation and the spraying port (4) to rotate in response to the rotation of the motor (5) as described above When the snow remover loaded in the main body 3 is discharged through the snow remover discharge hole 31, it has a form that immediately falls to the bottom of the road or the upper surface of a specific component of the dump truck, so that it may not be evenly sprayed on the road. Of course, there is a fear that the snow blowing agent is discharged to the side of the road through the snow blowing discharge hole 31 by the strong wind, etc. blown off and buried in the body of the dump truck.

Therefore, in the present invention, the snow removal guide plate 32 is additionally installed at the front of the snow removal outlet 31 of the main body 3, but the inclination angle θ1 of about 25-35 degrees toward the rear wheel side of the dump truck. The snow removal agent loaded in the main body 3 by the snow removal and conveying and discharging spout 4 rotates in response to the rotation of the motor 5 by installing the same through the snow removal discharge hole 31. When discharged, the snow removal guide plate 32, which is installed at an inclination of about 25-35 degrees without being dropped on the road floor or a specific component of the dump truck, is evenly sprayed on the road.

Therefore, it is possible to prevent corrosion of a specific part of the dump truck due to snow removing agent and to increase snow removing effect. Even though there is a strong wind on the road site where snow removing agent is applied, the snow removing agent of the main body 3 is used. The snow remover discharged through the discharge hole 31 descends on the snow remover guide plate 32 installed to the road, and is sprayed on the road, so that the snow remover itself is not blown by the wind, and the snow remover is the body of the dump truck. There is no risk of getting on the back, which can prevent corrosion of certain components including itself.

Meanwhile, the snow removing agent conveying and discharging and spraying holes having a configuration in which the screw 42 and the snow removing agent propeller 43 which are wound in opposite directions to both sides about the intermediate point of the rotating shaft 41 are installed ( When 4) has a shape in which the bottom of the main body 3 is pivotally rotatable as it is, the weight of various snow removing agents loaded into the main body 3 is applied to the snow removing agent conveyance and discharge and the entire spraying port 4. In this case, the two screws 42 of the snow removing and discharging and the spraying port 4 are fixedly installed in the form in which they are wound in opposite directions on the rotary shaft 41, but do not receive a great sense of pressure. The propellers 43, which have a constant angle at both ends and are welded at right angles to the outer circumferential surface of the rotating shaft 41, have a form in which a load of snow removing agent is applied to the entire surface, so that a lot of heavy pressure is applied to the snow removal by the motor 5. My There is a fear that the propellers 43 are burned out when the conveyance and discharge and the spout 4 are rotated.

Therefore, in the present invention, the inner surface of the front plate of the main body 3 located above the propeller 43 of the snow removal and conveying and discharging and discharging of the snow removal agent 4 at both inner side portions of the lower body 3 and FIG. As shown in Fig. 4, the intermediate pressure preventing plates 35 are installed to have an inclination angle θ2 of 45 to 55 degrees, respectively, and the lower end of the intermediate pressure preventing plate 35 has a rotary shaft 41 of the snow removal agent feed and discharge and the sprinkling openings 41. ) It was installed to reach a position almost coincident with the center line.

Therefore, the snow removal agent located on the propeller 43 of the snow removal and transporting and discharging of the snow removing agent loaded on the inside of the main body 3 is installed in the snow removing and conveying and discharging opening 4. Since only about half of the propellers 43 are introduced into the propellers 43, the feeling of pressure due to the load of the snow removing agent is also reduced to about 1/2 so that the propellers 43 are damaged by the heavy pressure of the snow removing agent. It can be prevented beforehand.

In addition, when the front and rear plates of the main body 3, which have a relatively wide width corresponding to the width of the loading box of the dump truck, are left as they are, the front and rear surfaces of the main body 3 are spread outwardly or applied externally by the load of the snow removing agent. There is a risk of contracting or crushing inward by the pressure.

Therefore, in the present invention, several gap retaining rods 36 are disposed on the upper and rear plates of the main body 3 at positions of the upper and lower parts of the snow removing agent and the dispersing agent 4 at the lower inner surface of the main body 3. By installing at regular intervals, the front and rear plates of the main body 3 can be prevented from contracting or crushing inward by pressure applied from the outside or by pressure applied from the outside. .

In addition, the apparatus of the present invention has a form that is detachably fixed to the front surface of the loading box of the dump truck as shown in Figure 1 so that the main body (3) in case of having to look inside or climb on the loading box itself during use. In the vertical direction at both sides of the), it is preferable to further install several handles and the footrest 37 at a predetermined interval.

In addition, when the upper opening of the main body 3 is left as it is, various foreign matters may flow into the interior of the main body 3, and thus the lid body 38 having the handle 381 is provided at the upper opening of the main body 3. It is preferable to install them, but such a lid 38 may be detachably installed from an opening of the main body 3 as shown in FIG. 3, and the lid body contacted with the rear surface of the main body 3 as shown in FIG. 2 ( A plurality of hinges 382 may be provided between the rear portions of the rear portion 38 to open and close the lid 38 to the front head 1 side of the dump truck.

On the other hand, the apparatus of the present invention is located in the space formed between the front head (1) and the loading box (2) of the dump truck as described above, and then the main body (3) is loaded using the fixing means (2) In this case, the widths of the spaces formed between the front head part 1 and the loading box 2 of the dump truck are not only different from each other depending on the type or structure of the dump truck, but the width itself is very wide. Therefore, since the width between the front and rear plates of the actual body 3 is relatively narrow, it may be difficult for an operator to enter and exit the inside of the body 3 and to inspect or repair the internal components.

Therefore, in the present invention, by forming a rectangular check opening 33 having a size that allows the inspector to fully enter and exit the central portion of the main body 3, the cover 34 is detachably installed, When the inspection or maintenance of the components installed therein is necessary, the cover 34 is removed from the rear plate of the main body 3 and the inspection opening 33 enters the interior of the main body 3 to perform inspection and repair work. Can be.

Although the above-described embodiments have been described with respect to the most preferred embodiments of the present invention, it is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention.

As described above, according to the apparatus of the present invention, a snow removing sand and calcium chloride spreading device capable of spraying a snow removing agent (sand or calcium chloride) to be sprayed for snow removal is placed in a space between the front head of the dump truck and the loading box. Removably fixed to the unit does not interfere with cargo loaded in the dump truck's loading box at all, eliminating the waste of time and labor required for installation and dismantling of the spreading device. It is a very useful invention such that it is possible to increase the snow removal effect without affecting the driving of the dump vehicle at all, and to secure the safety of the snow removal vehicle itself.
