v ditch bucketThis invention relates to machinery for digging ditches or trenches in the v trenching bucket and in particular to a device which converts a normally stationary machine into a continuous trenching machine. The device comprises an attachment for the bucket of a backhoe which converts the backhoe into a moving trencher, providing a V shaped ditch for installation of piping or conduit or for the creation of fire breaks. The backhoe is a primarily a ditch digging machine which is conventionally operated by placing the backhoe in one position and digging the ditch to the required depth to the extent that the arm of the backhoe will reach and then moving the machine forward and repeating the process. Various shapes of ditches may be excavated by changing the bucket or the v trenching bucket. Winstrol gep opiniones the installation of the present invention the conventional rectangular bucket of a backhoe is converted to a V shaped trenching tool, permitting the backhoe to dig a v trenching bucket or create a fire break while moving v trenching bucket forward and to vary the depth of the trench as it moves along.
Trencher (machine) - Wikipedia
A trencher is a piece of construction equipment used to dig trenches , especially for laying pipes or electrical cables , for installing drainage , or in preparation for trench warfare. Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor , to very heavy tracked heavy equipment.
Trenchers come in different sizes and may use different digging implements, depending on the required width and depth of the trench and the hardness of the surface to be cut. A wheel trencher or rockwheel is composed of a toothed metal wheel. It is cheaper to operate and maintain than chain-type trenchers.
It can work in hard or soft soils, either homogeneous compact rocks, silts, sands or heterogeneous split or broken rock, alluvia, moraines. This is particularly true because a cutting wheel works by clearing the soil as a bucket-wheel does, rather than like a rasp chain trencher. Consequently, it will be less sensitive to the presence of blocks in the soil.
They are also used to cut pavement for road maintenance and to gain access to utilities under roads. Due to its design the wheel may reach variable cutting depths with the same tool, and can keep a constant soil working angle with a relatively small wheel diameter which reduces the weight and therefore the pressure to the ground, and the height of the unit for transport.
The cutting elements 6 to 8 depending on the diameter are placed around the wheel, and bear the teeth which are more or less dense depending on the ground they will encounter. These tools can be easily changed manually, and adjusted to allow different cutting widths on the same wheel.
The teeth are placed in a semi-spherical configuration to increase the removal of the materials from the trench. The teeth are made of high strength steel HSLA steel , tool steel or high speed steel or cemented carbide. When the machine is under heavy use, the teeth may need to be replaced frequently, even daily. A chain trencher cuts with a digging chain or belt that is driven around a rounded metal frame, or boom. It resembles a giant chainsaw. This type of trencher can cut ground that is too hard to cut with a bucket-type excavator , and can also cut narrow and deep trenches.
The angle of the boom can be adjusted to control the depth of the cut. To cut a trench, the boom is held at a fixed angle while the machine creeps slowly. The chain trencher is used for digging wider trenches telecommunication, electricity, drainage, water, gas, sanitation, etc.
The excavated materials can be removed by conveyor belt reversible either on the right or on the left side. There are various methods for excavating trenches in rock — principally drill and blast, hydraulic breakers and chain trenchers. Selection of a trench excavation method must take into account a range of rock and machine properties. It is suggested that the advantages of using chain trenchers in suitable rock outweigh the limitations and may have cost benefits and fewer adverse environmental effects compared with alternative methods.
A micro trencher is a "small rockwheel" specially designed for work in urban area. It is fitted with a cutting wheel that cuts a microtrench with smaller dimensions than can be achieved with conventional trench digging equipment. These machines are sometimes radio-controlled. With a micro trencher, the structure of the road is maintained and there is no associated damage to the road. Owing to the reduced trench size, the volume of waste material excavated is also reduced.
Micro trenchers are used to minimize traffic or pedestrian disturbance during network laying. They may also be used to install FTTx connections.
A micro trencher can work on sidewalks or in narrow streets of cities, and can cut harder ground than a chain trencher, including cutting through solid stone. Landscapers and lawn care specialist may use a portable trencher to install landscape edging and irrigation lines. These machines are lightweight around pounds and are easily maneuverable compared to other types of trenchers. The cutting implement may be a chain or a blade similar to a rotary lawn mower blade oriented so that it rotates in a vertical plane.
A tractor mount trencher is a trenching device which needs a creeping gear tractor to operate. This type of trenchers is another type of chain trencher. The tractor should be able to go as slowly as the trencher's trenching speed. A trencher may be combined with a drainage pipe or geotextile feeder unit and backfiller, so drain or textile may be placed and the trench filled in one pass.
