Description

  The present invention relates to a vegetation cutting device, and more particularly to a vegetation cutting and recovery device that can be used by being attached to and detached from a construction machine such as a power shovel.

  2. Description of the Related Art Conventionally, there are known a mowing machine and a cutting machine for cutting a plant that are attached to a construction machine such as a power shovel. (For example, refer to Patent Document 1 and Patent Document 2.)

  In these conventional mowers, a blade such as a so-called hammer knife attached to a rotating drum with two plate members bent in a U-shape back to back and their tips open in a Y-shape is used. It is used, and this rotating drum is rotated to cut down vegetation.

  However, these conventional mowers are effective for harvesting vegetation on rough terrain and slopes, but they require collection work using a dedicated collection device or manual collection work to collect the vegetation after logging. Therefore, it took a lot of time and money.

  Therefore, there has been proposed a mowing machine that can be attached to and detached from the arm tip of a power shovel by rotating a release cylinder that is operated by a hydraulic pump and pivotally attaching a cage portion that discharges the stored grass (see, for example, Patent Document 3). ).

  However, the mowing machine has a configuration in which the car portion is driven by a hydraulic pump, and is driven by an engine mounted on the mowing machine. Therefore, fuel is required and a problem in work safety remains.

  The present invention has been made in view of the above-described conventional problems, and is detachably attached to a construction machine such as a power shovel, cuts and stores vegetation, and is driven by power supplied from a power shovel battery. A cutting and collecting device for cutting and harvesting a grass having a lid that can be opened and closed by the above.

  For this reason, the cutting and harvesting device of the present invention is detachably provided on one side of the cover body that is equipped with a rotary logging section to which a number of hammer knives are attached, and is formed by expanding the diameter from the opening of the cover body. A housing for housing the vegetation cut by the felling portion, a pair of lid portions that are provided at a lower portion of the housing and that rotate about a rotation shaft, and a drive unit that opens and closes the lid portion. The first characteristic is that the vegetation cut by the rotary type cutting unit is housed in the box.

  The driving means is provided on the housing and includes a link mechanism that rotates the lid, and a drive motor that drives the link mechanism, and is driven by power supplied from a construction machine such as a power shovel. The second feature.

  For the power supply from the construction machine, a battery or the like is effectively used, and the machine operator can open and close the lid simultaneously with the operation of the construction machine.

  According to the grass cutting and collecting apparatus according to the present invention, it is possible to store the vegetation cut by the rotary cutting section with a large number of hammer knives in the buttock. It has an excellent effect of not requiring a collection operation.

  In addition, since the lid is opened and closed by a motor driven by power supplied from the construction machine battery, the worker can work safely and can move and transship the harvested vegetation in parallel with the operation of the construction machine. Has an excellent effect.

It is a perspective view of the grass cutting and collecting apparatus of the present invention. It is front explanatory drawing of FIG. It is side surface explanatory drawing of FIG. It is explanatory drawing of a rotation type felling part. It is side explanatory drawing which shows the closed state of the buttocks of a vegetation felling collection apparatus. It is side explanatory drawing which shows the open state of the buttocks of a vegetation cutting collection apparatus.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a grass cutting and collecting apparatus according to the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a side view of FIG. 1, FIG. Side explanatory drawing which shows the closed state of the buttocks of a collection | recovery apparatus, FIG. 6 is side explanatory drawing which shows the open state of the buttocks of a vegetation cutting and collecting apparatus.

  As shown in FIGS. 1 to 3, the cutting and harvesting apparatus 1 of the present invention includes a cover body 2 having a rotary type felling section and a housing 3 detachably attached to one end side of the cover pair 2. , And is detachably attached to a top end portion 5 of a power shovel as a construction machine via a bracket 4 on an upper portion of the cover body 2.

  The cover body 2 is made of steel and is formed in a box shape with an open bottom, and a hydraulic motor 6 that rotates a rotating shaft of a rotary felling section, which will be described later, is attached to a side surface of the cover body 2 and is connected from a hydraulic source of a power shovel. The two hoses 7 are supplied with hydraulic pressure.

  Further, a plurality of chains 8 are suspended in a comb-like manner at the lower front side of the cover body 2 to prevent the cut vegetation from scattering outside the cover body 2.

  The housing 3 is formed in a pentagonal columnar box by a steel frame 9 and a steel net 10 and is detachably attached to the rear opening of the cover body 2, and a lid that can be opened and closed at the lower part. 11 and 12 are attached and can be opened and closed by a driving device described later.

  FIG. 4 shows the rotary cutting unit 13 disposed horizontally in the cover body 2. The rotary cutting unit 13 has a plurality of mounting brackets 15 spirally arranged on the surface of the cylindrical rotating shaft 14 at a predetermined interval and pitch in the longitudinal direction and the circumferential direction of the rotating shaft 14, and the mounting bracket 15. And a hammer knife 16 that is rotatably mounted in the circumferential direction of the rotary shaft 14 and is rotatably held by rotation support members 17 that are respectively attached to the centers of the two side surfaces. And rotation of the hydraulic motor 6 mentioned above is transmitted to the rotating shaft 14 by a rotation transmission means (not shown), and the rotary type cutting part 9 rotates.

  The mounting bracket 15 is arranged at a predetermined pitch in the longitudinal direction and the circumferential direction of the rotary shaft 14, holds a plurality of hammer knives 16 so as to be swingable, and does not cause interference due to swinging and turning of the hammer knives 16. The rotary cutting of the rotary type cutting unit 9 enables efficient cutting of the vegetation.

  5 and 6 show the side surface of the heel part 3 of the vegetation cutting and collecting apparatus 1 and show the open / closed states of the lids 11 and 12. As shown in the drawing, an electric motor 18 and a link member 20 that transmits drive via a chain 19 are attached to the side surface of the housing 3, and the link member 20 is connected to the lids 11 and 12, respectively. Yes. Then, electric power is supplied from the power shovel side battery (not shown) via the cable 21 to rotate the electric motor 18, and the lids 11 and 12 are opened and closed via the chain 19 and the link member 20.

  By cutting the grass felling and collecting apparatus 1 having the above-described configuration to the tip 5 of the excavator and moving the excavator while rotating the rotary felling portion 9, the felling of the plant becomes possible. Moreover, the felled vegetation is housed in the housing 3 from the rear opening while being crushed by the Hammer knife 16.

  The vegetation housed in the housing 3 can be loaded on a predetermined storage location or a dump truck for movement by opening the lids 11 and 12.

  As described above, according to the grass cutting and collecting apparatus of the present invention, a lid that is detachably attached to a construction machine such as a power shovel, cuts and stores the grass, and is opened and closed by a motor driven by power supplied from the battery of the power shovel. Depending on the part, the stored vegetation can be transshipped.
