A grass collection container for a grass mowing machine includes a bag or hopper attached to a support frame under the plastic top cover with air permeable panels, and a flexible sound barrier curtain attached to the support frame over the air permeable panels. The flexible sound barrier curtain has a thickness of between about 1 mm and about 5 mm. An air passage is provided between the bag or hopper and the flexible sound barrier curtain.

A vehicle is wrapped by an adhesive film which is then slit by applying first tape to the vehicle having a longitudinally extending filament carried by the tape at a position spaced from the side edges. A second tape is applied over the film at the first tape body so as to bridge to each side of the filament and pulling the filament so as to tear through the film and the first ad second tapes body with the second tape applying a force to the film acting to reduce tendency of the film to pull away from the object during the cutting by the filament as the filament is pulled.

A replaceable-blade cutting insert for corner milling cutters has a first and second surface; a third and fourth surface connected to a first side edge and a second side edge thereof respectively; and a fifth and sixth surface connected to a first edge and a second edge of the first surface and the second surface respectively. The first surface is used as rake face, the third surface is used as an outer perimeter flank face, and the fifth surface is used as a forward flank face. A twisted surface is disposed on a section of the third surface, forming a ridge line that acts as a main cutting edge intersecting with the first surface and interposed between the third and first surface. The first and second surface can be positioned with a height offset relative to each other so that at least one set of diagonal corners are projected.

A plasma tracking fixed-length flying saw, including a flying saw trolley, a speed measuring device, an electrical control system, a driving system, a fixture and a guide rail base, the driving system is connected to the flying saw trolley sitting on the guide rail base, and the speed measuring device is connected to the electrical control system. A plasma cutting device is installed on the flying saw trolley. The plasma cutting device is composed of a plasma gun installed on a profiling frame, and the outer edge of the profiling frame is connected with a rotating motor according to a transmission device. The advantages of the present invention: 1. Adopt no less than two plasma guns to cut at the same time, which speeds up the cutting speed and shortens the synchronous stroke, making it possible for plasma cutting to be used for online dynamic tracking and cutting to length; 2. Simple structure, low weight Lightweight, compatible with cutting pipes and steel profiles of different shapes, easy to change varieties; 3. Low noise, good incision quality, no burrs; 4. Less iron filings, safe, avoiding the danger of easy injury after the saw blade is broken; 5. The utility model has the advantages of high efficiency, low consumption cost and good development prospect.

The invention discloses a hot-press sintering rope saw bead string with evenly-distributed grinding particles. The bead string is composed of a casing work layer and a base body, and is characterized in that the grinding particles on the casing work layer are evenly distributed in the space. The casing work layer is formed through stacking, hot pressing and sintering of a plurality of layers of cutting unit rings. The grinding materials in cutting unit ring blanks are arranged in order along the circumference concentric with the center axes of the cutting unit rings. According to the manufacturing process of the bead string, the cutting unit ring blanks with the evenly-distributed single-layer grinding materials are manufactured in an alloy die cold pressing manner; string beads are strung to the base body according to the uniform same direction; the string beads are placed in a graphite sintering die, and the rope saw bead string with the grinding particles evenly distributed in the space is obtained through hot-press sintering forming; and the grinding materials are evenly distributed in the whole space, uniform consumption of the string beads is guaranteed, eccentric wear scrapping caused by uneven grinding particle distribution is avoided, and the problem about the cutting quality caused by eccentric wear scrapping is solved. The usage amount of the grinding particles is reduced, and cost is saved. Orderly distribution of diamonds can be conducted without a bonding agent or an auxiliary template or the like, and quality guaranteeing and high efficiency are achieved.

A pad supporting frame has a carrier board and a supporting structure. The supporting structure is detachably disposed on the carrier board. The supporting structure is detachably disposed on the bottom surface of the carrier board. In delivery, the carrier board and the supporting structure can be stacked separately for increasing the utilization of the delivery space. Molds of the carrier board and the supporting structure can be made separately for decreasing the volumes of the molds. For cutting a pad disposed on the carrier board, the carrier board can be directly disposed on the tabletop. The carrier board will not be deformed and the cutting quality of the pad is improved.

The invention relates to the technical field of whole wood furniture, and discloses a cutting auxiliary device for whole wood furniture processing with high safety, which comprises a casing, the outer side of the casing is fixedly connected with a base; Perform intermittent reciprocating rotation to provide power source for subsequent fixing operations. The rotation of the first turntable causes the blocks to approach each other and then move away from each other, automatically fixing the wood to prevent the wood from shaking and reducing the cutting quality. It is easy to take the wood or adjust the cutting point of the wood. The rotation of the fourth turntable causes the push rod to drive the connecting plate to perform intermittent reciprocating motion, which automatically pushes the wood to the cutting place, which is conducive to the cutting operation, frees hands, and avoids manual When the material is pushed, the hand may be cut, and the wood will be automatically moved away from the cutting tool after cutting, which greatly reduces the probability of the cutting tool hurting people and ensures the safety of the staff.
