Description

  The present invention relates to a dust collector for a dry cutter provided in a dry cutter used in paving road construction or the like, and a dry cutter provided with the dust collector.

  In construction related to wiring and piping for water, gas, electricity, telephones, etc., some paved roads such as asphalt may be cut using a cutter. The cutter is provided with a blade, and the blade is pressed against the paved road while rotating at high speed to cut the paved road. As a cutter, there is a wet cutter that sprays water on the road surface that presses the blade and mixes the dust generated when cutting paved roads such as asphalt with water to prevent the dust from scattering. Necessary and dusty water cannot be completely recovered, and the recovered water is highly viscous and requires a lot of cost and labor to separate and discard the dust from the water.

  For this reason, the present condition is using the dry cutter (dry cutter) which does not require the water which replaces a wet cutter. The dry cutter sucks dust generated when cutting asphalt with a blade together with air and collects it with a dust collector. For example, a blade and a paved road to be cut with the blade are covered with a cover, dust generated by cutting the blade is sucked together with air in the cover, the sucked air is guided to the cyclone of the dust collector, and the dust is collected. The dust that could not be recovered in the process is recovered with a filter to prevent the dust from scattering.

  However, since most of the sucked dust is in the form of fine powder, it is difficult to recover with a cyclone, and much of it may be recovered with a filter. In this case, for example, when a cutting operation of only about 10 m is performed, the filter is clogged, and the cutting operation is interrupted, and the dust collector of the dry cutter must be disassembled to clean or replace the filter.

Four connecting frames 6e are provided at 90 ° intervals in the circumferential direction of the first to fourth ring frames.

  An inner bag 5 is provided on the inner side of the outer bag 4 at a distance from the inner surface of the outer bag 4. The inner bag 5 is a filter medium that captures dust generated when the paved road is cut by the blade 14 and is formed into a bottomed cylindrical bag shape. The filter medium may be the same material as the outer bag 4 or a different material, and is formed of, for example, a woven fabric or a non-woven fabric. The inner bag 5 is preferably formed in a bottomed cylindrical shape that is smaller in diameter and axial length than the outer bag 4 and is gradually reduced in diameter toward the bottom. The bottom portion of the inner bag 5 is formed in, for example, a substantially disk shape. Although the inner bag 5 is provided inside the outer bag 4, it may be provided in the upper region 2 a other than the inner side of the outer bag 4.

  The inner bag 5 is attached to a swinging member 7 that swings when the outer bag 4 moves to drop dust, with the opening facing upward. The rocking member 7 includes, for example, four connecting frames in which three ring frames 7a, 7b, 7c arranged at intervals in the height direction are arranged at 90 ° intervals in the circumferential direction of the ring frames 7a, 7b, 7c. 7d and connected to form a bowl. The length of the swing member 7 in the axial direction is formed shorter than the length of the inner bag 5 in the axial direction, for example. One end of a spring 70 is attached to the ring frame 7 c above the swing member 7. The other end of the spring 70 is attached to the second ring member 32 of the seal member 3. The spring 70 is a spring on which a tensile tension acts, and is, for example, a tension coil spring. Four springs 70 are provided at intervals of 90 ° in the circumferential direction of the ring frames 7a, 7b, 7c. As a result, when the sealing member 3 is placed on the open end of the container main body 21 and further the cover member 22 is put on the open end of the container main body 21 to seal the container main body 21, the outer bag 4 drops the dust. Therefore, the swinging member 7, that is, the inner bag 5, swings when moved.

  A plurality of string members for fastening to the ring frame 7c above the swing member 7 are provided at the peripheral edge of the opening of the inner bag 5 at intervals in the circumferential direction. In addition, attachment of the rocking | swiveling member 7 of the inner bag 5 is not limited to a string member, You may make it perform by another means. As a result, the inner bag 5 is attached to the swinging member 7 in a state of hanging down in the swinging member 7. The inner bag 5 is attached to the seal member 3 via the swing member 7 and the spring 70, and the seal member 3 functions as a flange of the inner bag 5. That is, the inner bag 5, the swinging member 7, the spring 70, and the seal member 3 can be made into one unit. Moreover, it is preferable that the inner bag 5 is attached so that the opening end is positioned below the opening end of the outer bag 4, that is, in the outer bag 4.

  In the inner bag 5, it is preferable that a shape holding member 8 that holds the inner bag 5 in a substantially cylindrical open state is inserted. The shape holding member 8 may be formed of, for example, a member that is similar to the inner peripheral wall of the outer bag 4 and is slightly smaller than the inner peripheral wall, and has a mesh or a high opening ratio. You may form only with a flame | frame. When the shape holding member 8 is formed of only a frame, for example, a first ring frame 8a formed on the bottom 5a of the inner bag 5 and having an outer diameter slightly smaller than the diameter of the bottom 5a of the inner bag 5, When the first ring frame 8a is placed on the bottom 5a of the inner bag 5 above the first ring frame 8a, the diameter of the inner wall located near the opening end of the inner bag 5 and in the vicinity of the opening end of the inner bag 5 The second ring frame 8b formed with a slightly smaller outer diameter and the first and second ring frames 8a and 8b are connected in the vertical direction and are provided at 90 ° intervals in the circumferential direction of the ring frames 8a and 8b. The four connecting frames 8c are formed in a bowl shape.

  In the vicinity of the opening end portion of the inner bag 5, a lead-out port for the pipe 19 connected to the blade cover 15 is preferably located. Thus, air containing dust is led out from the pipe 19 toward the inner bag 5. As long as the pipe 19 is connected to the upper region 2a and air containing dust is led out from the pipe 19 into the inner bag 5, the position of the outlet is not limited.

  In the lower region 2b of the container main body 21, a suction port 25 for sucking the lower region 2b is provided. The suction port 25 is preferably provided, for example, below the peripheral wall of the upper container body 21a. One end of a suction pipe 26 having a suction pump is connected to the suction port 25. The other end of the suction pipe 26 is disposed so as to be open to the atmosphere. The other end of the suction pipe 26 may be connected to the blade cover 15 to circulate the air, or the other end of the suction pipe 26 may be connected to the engine 13 to use the air for cooling the engine 13. It may be.

  A dust removing member 91 is disposed facing the outer bag 4 in the lower region 2 b in the container 2. The dust removing member 91 is preferably disposed, for example, in the upper container main body 21 a and in the vicinity of the bottom 4 a of the outer bag 4. The dust removing member 91 strikes and swings the outer surface (bottom surface), which is the lower surface of the bottom portion of the outer bag 4, and drops dust adhering to the outer bag 4, which is a filter medium, to the lower side of the container 2. The dust removing member 91 is preferably formed so as to expand on a plane, for example, a flat plate having holes, a net member, a member obtained by bending or connecting rod members, a combination of these, or the like. . Specifically, the dust removing member 91 is formed of, for example, a circular net member. One end of a bar 92 is fixed to the central portion of the net member, and a dust removing member 91 is disposed in close proximity to the bottom surface of the outer bag 4.

  The bar 92 extends in the horizontal direction and penetrates the lower peripheral wall of the upper container body 21a. The other end of the bar 92 located outside the upper container body 21a is provided with a handle 93 that is an operation unit. In addition, a ball joint 94 that can move the dust removing member 91 up, down, left, and right while operating the handle 93 and maintaining a sealed state is provided at a portion of the bar 92 that passes through the upper container body 21a. As a result, the handle 93 can be operated to strike and swing the bottom surface of the outer bag 4 with the dust removing member 91 so that the dust adhering particularly to the outer bag 4 can be dropped. The dust removing member 91, the bar 92, the handle 93, and the ball joint 94 constitute dust removing means. The dust removing means is operated from the outside of the container 2 (upper container body 21a) and is particularly attached to the outer bag 4. Any configuration may be used as long as dust can be dropped.

Next, the case where a part of paved roads, such as asphalt, is cut | disconnected using the dry cutter 10 comprised as mentioned above and the dust collector 1 for dry cutters is demonstrated.
First, only the blade cover 15 is moved downward to bring the seal member 16 of the blade cover 15 into contact with the road surface of the paved road, and a desired portion to be cut is covered with the blade cover 15. At this time, the blade 14 is located at a position away from the road surface. Next, the engine 13 and the suction pump are driven to rotate the blade 14 at a high speed. While rotating the blade 14 at a high speed, the blade 14 is moved downward and pressed against the paved road, and the dry cutter 10 is pushed forward to cut the paved road.

  When the paved road is cut by the blade 14, dust is generated. At this time, by driving the suction pump, the dust is sucked into the suction chamber 17 together with the air and led out through the pipe 19 toward the inner bag 5 in the upper region 2 a in the container 2 of the dust collector 1. Air flows through the inner bag 5 and the outer bag 4 to the lower region 2 b, and the dust is captured by the inner bag 5 and the outer bag 4. As a result, the air from which the dust is separated flows from the suction port 25 to the suction pipe 26.

  When the amount of dust trapped in the outer bag 4 increases, the airflow resistance increases and the suction force decreases. Therefore, when the suction force decreases or before it falls, for example, the container 2 (upper container body 21a) regularly projects outside. The handle 93 is operated to strike and swing the dust removing member 91 against the bottom surface of the outer bag 4 to drop the dust adhering to the outer bag 4. Thereby, cleaning of the outer bag 4 is performed.

  That is, dust is introduced into the inner bag 5 together with air, so that the dust hits the inner bag 5. At this time, most of the dust is in the form of fine powder, but also includes powder that is not fine powder. This relatively large dust that is not in the form of fine powder hits the inner bag 5 and accumulates in the inner bag 5 by gravity. Although some fine dust is trapped by the inner bag 5, it is trapped by the outer bag 4 when the air passes through the outer bag 4 from the opening of the inner bag 5 together with the air. The In this way, relatively large dust is captured by the inner bag 5, and fine dust is captured by the outer bag 4. At this time, since the outlet port of the pipe 19 faces the opening of the inner bag 5, a relatively large dust can be more reliably captured by the inner bag 5.

  When dust trapped in the outer bag 4 accumulates, it becomes a lump. The dust that has become a lump appears outside the outer bag 4 because the lower region 2b, which is the outer side of the outer bag 4, is sucked and the dust is in a fine powder form. In this state, when the bottom surface of the outer bag 4 is beaten and swung by the dust removing member 91, the dust that has come out from the outer bag 4 to the outside (the lower region 2b side), that is, the dust attached to the outer bag 4 falls. To do. Thereby, cleaning of the outer bag 4 is performed. The dust falling from the outer bag 4 falls into the lower container body 21b and accumulates at the bottom. When the dust removing member 91 strikes and swings the bottom surface of the outer bag 4, the impact and vibration caused by the hitting and swinging are transmitted to the inner bag 5 (swing member 7) via the spring 70, and the inner bag 5 is moved. Swing. Thereby, the dust that has come out from the inner bag 5 falls into the outer bag 4 and finally falls from the outer bag 4 into the lower container body 21b, so that the inner bag 5 is also cleaned.

  Therefore, the dry cutter 10 and the dry cutter dust collector 1 of the present embodiment can drop dust from the outer bag 4 simply by operating the handle 93 protruding outside from the container 2 (upper container body 21a). The outer bag 4 can be cleaned without interrupting the work, and smooth dust collection can be performed.

  Since the container 2 is formed by the container main body 21 and the lid member 22, the outer bag 4 and the inner bag 5 (seal member 3) are detachably attached between the container main body 21 and the lid member 22. The bag 4 and the inner bag 5 can be easily maintained and replaced, and the dust collector 1 can be easily disassembled and assembled. Further, by making the inner bag 5, the swinging member 7, the spring 70, and the seal member 3 into one unit, the inner bag 5 can be removed by removing the seal member 3 from the container 2. The dust collector 1 can be easily disassembled and assembled. By attaching the outer bag 4 to the seal member 3, the outer bag 4 can be easily maintained and replaced, and the dust collector 1 can be easily disassembled and assembled. Furthermore, the dust that has fallen from the outer bag 4 is formed by an upper container body 21a and a lower container body 21b that are divided into upper and lower parts, and the lower container body 21b is covered with a garbage bag 29 in advance. Since it accumulates in the garbage bag 29, dust can be easily treated.

  The shape holding member 6 is inserted into the outer bag 4 and the shape holding member 8 is inserted into the inner bag 5 so that the outer bag 4 and the inner bag 5 are each held in a substantially cylindrical open state. The dust collection processing by the outer bag 4 and the inner bag 5 can be performed efficiently and reliably. In addition, when the outer bag 4 is cleaned by being beaten and swung by the dust removing member 91 by inserting the shape holding member 6 into the outer bag 4 and holding it in a substantially cylindrical open state. In addition, since the impact and vibration due to beating and swinging of the dust removing member 91 are easily transmitted to the entire outer bag 4, the outer bag 4 can be reliably cleaned. Further, the bottom portion 4a of the outer bag 4 is formed in a flat plate shape, and the dust removing member 91 is formed so as to expand on a plane facing the bottom portion 4a of the outer bag 4, so that the dust removing member 91 is beaten and shaken. Shock and vibration due to movement can be transmitted through the entire outer bag 4, and the outer bag 4 can be reliably cleaned.
