Abstract
A kind of novel saw-tooth spade, including the spade plate and spade trousers connected as one, the front end of spade plate is blade, and shoulder is is stepped in the rear end of spade plate, and blade is arranged on the side of spade front edge of board width, and blade is the peak sword along spade plate length direction to front projection；The peak sword is triangular shape structure, and two sides of peak sword are put the first edge on a knife or a pair of scissors mouth；Spade plate on the side of blade homonymy with being provided with sawtooth；The sides and top of the sawtooth forms acute angle shape, and is to the inclined ramp structure in spade plate front above sawtooth.This sawtooth spade, the peak sword of spade front edge of board can effectively improve the driving power of spade plate, can effectively avoid it is unilateral long-term firmly caused by the unbalance situation of spade plate working face；The cutting force of spade plate can be effectively improved；Sawtooth is used cooperatively with peak sword, and unimodal sword is equipped with the unilateral sawtooth of homonymy, and bimodal sword is equipped with bilateral sawtooth.
Description
Technical field
It the utility model is related to a kind of sawtooth spade, specifically a kind of novel saw-tooth spade with peak sword and chamfered indentations.
Background technology
At present, in agricultural hand-held tool field, there are many sawtooth spades, especially in military project spade with broached-tooth design more
Generally.Existing sawtooth spade, the front end of its spade plate are generally traditional preceding convex triangular structure, the spade for also having Y-shaped structure
Plate, mouth, and mostly flat edge but the recess mostly in two sides of triangle or Y-shaped puts the first edge on a knife or a pair of scissors, this mouth that puts the first edge on a knife or a pair of scissors
Spade only has side stress in actual use, and easily generation cutting edge lopsided wear is serious, causes the situation that working face is unbalance.And show
Sawtooth on some spade plates, it is plane above sawtooth, when in use, simply plays a part of sawing repeatedly, sawing dynamics
It is smaller, it is more single using function.
Utility model content
The utility model is to be directed to technological deficiency existing for existing sawtooth spade, there is provided one kind is simple in construction, driving power is strong, cuts
Cut the novel saw-tooth spade of great efforts.
Realizing the technical scheme that above-mentioned purpose uses is：A kind of novel saw-tooth spade, including the spade plate and spade connected as one
Trousers, the front end of spade plate is blade, and the rear end of spade plate is to step on shoulder,
The blade is arranged on the side of spade front edge of board width, and blade is the peak along spade plate length direction to front projection
Sword；The peak sword is triangular shape structure, and two sides of peak sword are put the first edge on a knife or a pair of scissors mouth；
The spade plate on the side of blade homonymy with being provided with sawtooth；The sides and top of the sawtooth forms acute angle shape
Shape, and be to the inclined ramp structure in spade plate front above sawtooth.
The spade front edge of board, the both ends of width are respectively arranged with a peak sword.The both sides of spade plate are respectively arranged with sawtooth.
Spade front edge of board, one end of width are provided with peak sword.Side on spade plate with the peak sword homonymy is provided with saw
Tooth.Sawtooth shape at an acute angle, its stress direction are slope sword.
The cross section of the spade plate is the high arc surface structure in middle concave both sides.
Compared with prior art, this sawtooth spade disclosed in the utility model, the peak sword of spade front edge of board can be carried effectively
The driving power of high spade plate, and the front end of spade plate can be fabricated to by unimodal sword or bimodal sword according to actual design and service condition, it is single
Peak sword can reduce driving resistance, be more suitable for soil hardboard and be mingled with the bad working environments of garrulous bricks and stones, and it is different also to be available for left and right human hair combing waste power
People's unrestricted choice, can effectively avoid it is unilateral long-term firmly caused by the unbalance situation of spade plate working face；The sawtooth of spade plate side
It is inclined-plane above, and is forward arranged along spade plate length direction, the cutting force especially stress direction of spade plate can be effectively improved
Slope sword, there is good lateral incision power to smaller tree root；Sawtooth is used cooperatively with peak sword, and unimodal sword is equipped with the unilateral sawtooth of homonymy, bimodal
Sword is equipped with bilateral sawtooth.
Brief description of the drawings
Fig. 1 is the spade plate structure schematic diagram of the bilateral sawtooth of bimodal sword.
Fig. 2 is the spade plate structure schematic diagram of the unilateral sawtooth of unimodal sword.
Fig. 3 is broached-tooth design schematic diagram.
Fig. 4 is Fig. 1 A-A direction views.
In figure：Peak sword 1, spade plate 2, spade trousers 3 step on shoulder 4, sawtooth 5,6 above sawtooth, sawtooth side 7.
Embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Referring to accompanying drawing 1-4, this sawtooth spade disclosed in the utility model, including peak sword 1, spade plate 2, spade trousers 3, step on shoulder 4,
Sawtooth 5.
This novel saw-tooth spade, including the spade plate and spade trousers connected as one, the front end of spade plate are blade, the rear end of spade plate
To step on shoulder.Described blade is the force part of spade front edge of board, design of generally putting the first edge on a knife or a pair of scissors.And can be according to actual design and use
Situation, the front end of spade plate is fabricated to unimodal sword or bimodal sword.During if unimodal sword, blade is arranged on spade front edge of board width
Side, blade is peak sword along from spade plate length direction to front projection；During if bimodal sword, spade front edge of board, the two of width
End is respectively arranged with a peak sword.Peak sword is triangular shape structure, and the angle of the triangle at its peak blade tip end is 45-60 °, and peak sword three
My slope sword of two sides of angular structure, that is, put the first edge on a knife or a pair of scissors mouth.Accompanying drawing 1 is bimodal sword structure, and accompanying drawing 2 is unimodal sword structure.
Sawtooth is provided with the side of spade plate, setting and the peak sword of sawtooth match, the spade of unimodal sword, and sword institute is in place at peak
Corresponding sawtooth is set on the spade plate side for the side put；The spade of bimodal sword, set respectively on two sides of spade plate
Sawtooth.The sides and top of sawtooth forms acute angle shape, that is, the direction of stress is slope sword, and is to spade plate above sawtooth
The inclined ramp structure in front.Tilted above all sawtooth to a direction, as shown in Figure 3, in the upper surface of spade plate
Look, the inclined plane of sawtooth is forward arranged.
Preferably, the cross section of spade plate is the high arc surface structure in middle concave both sides, as shown in Figure 4.
