Abstract
A work machine according to the present invention optimally collects work chips, such as dust, produced during work. In a circular saw 10, a sawdust discharge port 27H and a cover opening 27J are formed in an inner cover 27, and a dust collecting chamber inlet 62L1 and a dust collecting chamber outlet 62L2 are formed in a dust collecting case 60. Furthermore, at least a portion of the dust collecting chamber inlet 62L1 and at least a portion of the dust collecting chamber outlet 62L2 are arranged at the same position in the vertical direction.
Claims15
A work machine, comprising:
- a base formed in a plate shape;
- a circular saw rotated around a shaft along a left-right direction by a motor and partially protrudes below the base;
- a housing supported by the base on an upper side of the base and accommodating the motor;
- a cover covering at least a part of the circular saw;
- and
- a dust collecting structure comprising a dust collecting chamber capable of collecting work chips produced by driving the circular saw, wherein
- the dust collecting structure is provided with:
- an inlet serving as an entrance of the dust collecting chamber,
- an inflow part connected with the inlet and serving as a passage of the work chips,
- an outlet serving as an exit of the dust collecting chamber,
- an outflow part connected with the outlet and serving as a passage for delivering air in the dust collecting chamber to an inner side of the cover, and
- a partition wall, wherein
- the cover is provided with a first opening for discharging the work chips from an inside of the cover towards the inlet and a second opening for introducing air from the outlet into the cover, and
- the inflow part extending from the inlet towards the first opening and the outflow part extending from the outlet towards the second opening are at least partially partitioned in the left-right direction by the partition wall, and
- a part of the partition wall is disposed adjacent to the cover and between the first opening and the second opening, and
- at least a part of the inlet and at least a part of the outlet are arranged at the same position in an up-down direction.
A work machine that performs processing work in a forward direction by a circular saw rotated around a shaft along a left-right direction by a motor, the work machine having:
- a cover covers at least a part of the circular saw;
- and
- a dust collection structure that collects dust produced by the processing work, in which the dust collection structure includes:
- a dust collecting chamber for storing the dust,
- a transfer part having an inflow part that delivers the dust to the dust collecting chamber and an outflow part that discharges air in the dust collecting chamber to an inside of the cover,
- a partition wall having a first partition part connected to a bottom of the dust collecting chamber and extending upward to partition the dust collecting chamber and the transfer part and partially partitions the inflow part and the outflow part in the left-right direction, and
- a communication part positioned above an upper end of the first partition part and communicating between the dust collecting chamber and the transfer part, wherein
- the cover is provided with a first opening for discharging the dust from an inside of the cover towards the inflow part and a second opening for introducing air from the outflow part into the cover,
- a part of the partition wall is disposed adjacent to the cover and between the first opening and the second opening, and
- the communication part is provided with an inlet connected to the inflow part and an outlet connected to the outflow part, and is configured such that positions of one end of the inlet and one end of the outlet in the left-right direction are different from each other.
A work machine, comprising:
- a base formed in a plate shape;
- a housing supported by the base on an upper side of the base and accommodating a motor for driving a circular saw;
- and
- the circular saw rotated around a shaft along a left-right direction by the motor and partially protrudes downwards from the base;
- a cover covers at least a part of the circular saw;
- and
- a dust collecting structure comprising a dust collecting chamber capable of collecting work chips produced by driving the circular saw, wherein
- the dust collecting structure is provided with:
- an inlet serving as an entrance of the dust collecting chamber,
- an inflow part connected with the inlet and serving as a passage of the work chips,
- an outlet serving as an exit of the dust collecting chamber,
- an outflow part connected with the outlet and serving as a passage for delivering air in the dust collecting chamber to an inner side of the cover, and
- a partition wall, wherein
- the cover is provided with a first opening for discharging the work chips from the inner side of the cover towards the inlet and a second opening for introducing air from the outlet into the cover,
- the partition wall has a first partition part extending in an up-down direction, a second partition part connected to the first partition part, and a third partition part connected to the second partition part,
- wherein the first partition part at least partially partitions both the inflow part and the outflow part from the dust collection chamber in a front-to-rear direction,
- the second partition part partitions the inflow part and the outflow part at least partially in the front-to-rear direction,
- and the third partition part partitions the inflow part and the outflow part at least partially in the left-to-right direction,
- the inlet and the outlet are provided on an upper side of the dust collecting chamber, and
- at least a part of the inlet and at least a part of the outlet are arranged at the same position in the up-down direction.
