Abstract
The utility model relates to a shoveling blade fixation device for a chain type trench digger matched with a tractor. The shoveling blade is fixed on a fixed plate which is capable of regulating a trench digging width. The fixed plate is fixed on two chain attaching plates on the same pin shaft 2. Thus, the chain of the trench digger is stressed uniformly and transmitted steadily, and therefore, working performance and the service life of the chain are comparatively improved. The trench digging width can be regulated, with a regulating range from 20 to 40 centimeters.
Description
The invention belongs to fastening devices with the sprocket-type ditching machine shoveling blade of tractor.
The operating principle of ditching machine is: the power of exporting from tractor is after gearbox slows down, drive chain by drive sprocket, rotate with certain linear velocity, on the attached plate of chain the shoveling blade is housed, chain and shoveling blade stretch into underground by knife rest, along with the rotation of chain is stretched into underground earth-digging cutter earth is dug out ground, thereby reach the purpose of trench digging.
The pipe-laying trencher of existing domestic Shanghai City agricultural machinery research institute all is directly to be fixed on the attached plate 3 of chain with external Japan, its shoveling blade of Australian ditching machine.There is following problem in the fixed form of this shoveling blade.
1. because shoveling blade 1 directly is fixed on the attached plate 3 of chain, do not have adjusting device, the width of trench digging is by the decision of the size of earth-digging cutter, is nonadjustable.
2. because shoveling blade 1 is to be fixed on the attached plate of chain, during shoveling, the attached plate 3 of chain that shoveling blade 1 is housed is subjected to bearing pin one end that bigger active force links to each other with the attached plate of chain and also is subjected to bigger active force, and another side is stressed less, produces the discontinuity phenomenon, makes the ditching machine chain drive not steady, produce bigger vibration, influenced the trench digging quality, made ditch not straight, bottom of trench, furrow bank injustice.
3. because vibration is bigger, pin-and-hole and bearing pin are worn and torn easily, bearing pin is easily got loose, influenced the application life of chain.
Fig. 1 is that the shoveling blade is fixed on a trench digging operating principle schematic diagram on the attached plate of chain.
Fig. 2 is that the shoveling blade is fixed on a structural representation on the attached plate of chain.
The present invention is directed to above-mentioned existing problem, a kind of shoveling blade fastening devices that evenly, can regulate the trench digging width simple in structure, stressed is provided.
Earth-digging cutter fastening devices provided by the present invention is: shoveling blade 1 is fixed on the fixed head 4, fixed head 4 is fixed on two blocks of attached plates of chain on the same bearing pin, its fixed head 4 be drilled with on the rectangle steel plate several to being used for fixing the hole of shoveling blade 1, the position of shoveling blade 1 can be adjusted on fixed head 4, thereby reach the purpose of regulating the trench digging width; Have one can the size of the attached plate 3 of former chain can be strengthened (arrive greatly to connect for boring and use) outside then bending and molding for the ear 6 of the plate 4 that is connected and fixed on the attached plate 3 of its chain, angle bending is 90 degree.Maybe the shoveling blade is changed on two blocks of attached plates of chain that directly are fixed on after the shape on the same bearing pin, or with other form with a shoveling blade, be fixed on two blocks of attached plates of chain on the same bearing pin.
The fastening devices of shoveling blade provided by the present invention is compared with the existing fixed mode, has the following advantages:
1. because the shoveling blade is on two blocks of attached plates of chain that are fixed on the same bearing pin, active force on the shoveling blade is born by two blocks of attached plates of chain, makes chain stressed evenly, stable drive, thereby improved the work quality of ditching machine, made that the ditch left is straight, bottom of trench, furrow bank be flat.
2. because chain is stressed evenly, stable drive, thus reduced vibration, reduced the wearing and tearing between the pin-and-hole bearing pin, prolonged the application life of chain.
Since fixedly have on the fixed head of shoveling blade can be for adjusting shoveling blade position several to the hole, thereby make the trench digging width-adjustable, adjustable range is: 20～40 centimetres.
Fig. 3 is the structural representation of shoveling blade fastening devices provided by the present invention.
Fig. 4 is a broad-adjustable operating principle schematic diagram of the present invention.
Among the figure: shoveling blade 1 is screwed on fixed head 4, and regulates the trench digging width by the hole above it 5, and the ear 6 on fixed head 4 and the same bearing pin 2 on two blocks of attached plates 3 of chain links.
Claims (2)
1, a kind of fastening devices of sprocket-type ditching machine shoveling blade, it is characterized in that: shoveling blade 1 is fixed on the fixed head 4, fixed head 4 is fixed on two blocks of attached plates of chain on the same bearing pin 2, have on the attached plate 3 of its chain one can be for the ear 6 of the plate 4 that is connected and fixed.
2,, it is characterized in that fixedly the fixed head 4 of shoveling blade is to be drilled with severally to diverse location above the block length square plate, is used for fixing the hole 5 of shoveling blade according to the fastening devices of the said ditching machine shoveling of claim 1 blade.
