Description

One handle multi-stylus soil subsoiling shovel

Technical field

The present invention relates to a kind of deep soil loosing shovel of soil deep-loosening machine, belong to agricultural mechanical field.Relate in particular to the handle multi-stylus soil subsoiling shovel that an a kind of handle connects multiple narrow spear.

Background technology

Spear is the critical component of soil deep-loosening machine deep soil loosing shovel, and basic structure mainly contains: cutter type, duck's foot type (arrow type) and double airfoil type, and various distortion is as bionical hook-type etc.Cutter type spear resistance is less, its width (meets native face perpendicular to unit direction of advance, lower same) narrower, shape has planar shaped and breakover shape, and the working resistance of planar shaped is less, structure is simple, intensity is high, easy to make, changes easily after wearing and tearing, most widely used a kind of subsoiling spear, this spear width is general >=50mm.

Existing research data shows: soil subsoiling particularly ultra-deep pine resistance is very large, and wherein spear resistance is close to even exceeding 2/3 of whole deep soil loosing shovel drag overall.Spear width is larger, and resistance is larger, and penetration performance is poorer.Penetrating angle, 8 ° of-12 ° of scopes, cuts soil resistance less, but in order to improve spear penetration performance, and the actual penetrating angle used is greatly about about 20 ° at present, even higher, and excessive penetrating angle causes larger cutting soil resistance.In addition, the various spears used in current production, comprise the cutter type spear that comparative resistance is less, the boundary condition (in Fig. 1 AB side) created and effectively utilize as shown in Figure 1 is difficult in work, therefore, meeting under range of condition of necessarily loosening the soil, the invention discloses one and wide cutter is become narrow cutter, a handle connects a handle multi-stylus soil subsoiling shovel of multiple narrow cutter.

The object of invention is: on the basis of existing various practical technique, reduces further soil subsoiling particularly under ultra-deep pine condition, the tractive resistance of cutting soil resistance and facility of perching knife, and improves spear penetration performance.

Summary of the invention

The technical scheme realizing foregoing invention is: the broad share point width generally used by current each deep soil loosing shovel reduces about 2/3, becomes the narrow point that width a is about 15mm-25mm, replaces a wide point, form a kind of novel narrow sharp deep soil loosing shovel with two or three narrow points.Concrete summary of the invention is as follows: a handle multi-stylus soil subsoiling shovel, it is characterized in that: deep soil loosing shovel is made up of a spade and the multiple narrow spear being configured in the upper and lower diverse location of spade, to make soil horizontal cross layered cutting, multiple narrow spear width is identical or different; Multiple narrow spear is divided into many groups along spade short transverse.

One handle multi-stylus soil subsoiling shovel is primarily of spade [1], and be positioned at the upper and lower diverse location of spade, penetrating angle is fitted in 8 ° of-12 ° of scopes, mutual spacing clutch, is shoveled face width degree greatly about formations such as multiple narrow spear [2] ~ [5] of 15mm-25mm, each narrow point can on demand manual control soil flow to.When the subsoiling degree of depth is less, when the thickness of hard tillage pan is also little, a handle multi-stylus deep soil loosing shovel configures [3] and [4] of one group of narrow point as Fig. 3, and preposition narrow point [4] creates the boundary condition of favourable drag reduction for rearmounted narrow point [3]; When the subsoiling degree of depth is larger, when the thickness of hard tillage pan is also large, the configurable upper and lower two groups of narrow points of deep soil loosing shovel are as Fig. 2 [3] and [4], [2] and [5] etc., and that group spear of top is at least made up of 2 narrow points, test shows, the one group narrow sharp lifting soil in top, can reduce the live load of the one group of narrow point in below, and reduce drag overall.If the former broad share point band wing, loosen the soil wider range, and narrow spear width a also can be made less, and as 15mm, so, available three narrow points [6], [7], [8] replace an intrinsic wide point, as shown in Figure 4.

Transverse direction (perpendicular to unit direction of advance) the distance b of each narrow spear and longitudinal (unit direction of advance) are if distance c is too small, then may form common compacting soil wedge, block up soil, causes resistance to increase; If b and c is excessive, rear point of a knife will be made cannot to make full use of the favourable border of front point of a knife creation, finally cause resistance increase of loosening the soil.Different spear structures has different scopes of loosening the soil, and the horizontal cutter that the present invention provides depends on the scope of loosening the soil of existing wide point of a knife apart from b, longitudinal point width c depends on front point of a knife structure, and forms the position of favourable soil boundary.

Time burying in spade and spear coupling part, residing path soil by spear pine mistake, therefore, can not produce excessive soil-entering resistance herein.During normal work, native area is met perpendicular to unit direction of advance in this coupling part, and the projected area on plummet face is less, can not produce excessive to cut soil resistance.

Embodiment

Specific embodiment is provided below in conjunction with accompanying drawing.

Embodiment one: one handle two group four point layered deep digging shovel up and down

As shown in Figure 2, in plummet direction, soil layering is loosened the soil simultaneously, and that group spear of upper strata is made up of two narrow points, be adapted to the subsoiling degree of depth comparatively large, the occasion that the thickness of hard tillage pan is also larger, one group, top narrow point [2] and [5] lifting soil, the live load of the one group of narrow point [3] in below and [4] can be reduced, and reduce drag overall.

The sharp deep soil loosing shovel of embodiment two: handle two

On general deep soil loosing shovel basis, replace the result after a wide point with two narrow points, as shown in Figure 3.

Embodiment three: one handle tricuspid deep soil loosing shovel

Original tape wing deep soil loosing shovel, loosen the soil wider range.As shown in Figure 4, an intrinsic wide point of the band wing is replaced with the narrow spear [6] of three width a less (as 15mm), [7], [8].

In addition, as long as a handle connects multi-stylus, no matter the combination of point of a knife, structure how, can form other embodiments of the present invention.
