Abstract

The invention provides a dragging layered deep digging shovel, which comprises a fixed base, a dragging layered shovel handle, an upper layer shovel tip, a lower layer shovel tip and a shovel tip fixed bolt, wherein the dragging layered shovel handle is subjected to backswept dragging design, and is fixedly provided with the upper shovel tip and the lower shovel tip; when the dragging layered deep digging shovel operates, the two shovel tips are arranged at positions which are staggered front and back, the upper layer shovel tip is positioned in an upper soil layer, and the lower layer shovel tip in the rear is positioned in a bottom soil layer to achieve the effects of fore-and-aft staggering and layered deep digging, so the depth of soil which is subjected to the deep digging by each shovel tip is approximately a half that of the soil which is subjected to the total deep digging, and deep digging resistance is reduced effectively; and in the backswept design of the shovel handle, the shovel presses the soil downwards when entering the soil, so the upturning rate of soil blocks on a surface layer is reduced effectively.

Description

Towed layering deep soil loosing shovel

Technical field

The present invention relates to a kind of agricultural machinery, especially a kind of towed layering deep soil loosing shovel.

Background technology

Deep soil loosing shovel is mounted in the dark loose operation part that on the facility such as subsoiler soil is not stirred, and these parts are to be the dry land ploughing work of purpose with loose topsoil bottom soil.This kind operation helps retaining and conserveing soil moisture, and promotes plant growing.But present employed deep soil loosing shovel all is the single spear that leans out forward, and once dark pine is to the bottom topsoil, and the resistance that receives of deep soil loosing shovel is very big like this; The power of upwards pushing soil layer is also very big; Power consumption is very big during operation, and forms big soil block on the face of land easily, is easy to the evaporation of water in soil after the operation.

Summary of the invention

Power consumption is big when the invention solves operation, and forms big problems such as soil block on the face of land easily.

In order to overcome the above problems, the present invention has adopted following technical scheme to realize: a kind of towed layering deep soil loosing shovel comprises holder, towed layering spade, upper strata spear, lower floor's spear and spear set bolt.It is characterized in that: said spade adopts the towed design of sweepback, on towed layering spade, is fixed with upper and lower layer spear.When work; The position of staggering before and after two spears are arranged in, and the upper strata spear is arranged in the upper strata soil layer, and back lower floor spear is arranged in bottom solum; Stagger before and after having realized; The effect of dividing the layer depth pine, half of the approximate overall dark loose degree of depth of the degree of depth of the dark pine of each spear institute reduced dark loose resistance effectively like this; The design of the spade of swept-back is downward firming when burying, effectively reduced the top layer soil block on turn over.

Description of drawings

Below in conjunction with accompanying drawing the present invention is further specified.

Accompanying drawing is a towed layering deep soil loosing shovel structural representation.

Among the figure: 1, subsoiler frame; 2, holder; 3, towed layering spade; 4, upper strata spear; 5, lower floor's spear; 6, spear set bolt.

Embodiment

Below in conjunction with accompanying drawing the present invention is elaborated:

Referring to accompanying drawing, a kind of towed layering deep soil loosing shovel comprises holder 2, towed layering spade 3, upper strata spear 4, lower floor's spear 5 and spear set bolt 6.

Towed layering deep soil loosing shovel is connected on the subsoiler frame 1 through holder 2, and during work, the tractor-drawn subsoiler travels forward; Upper strata spear 4 and lower floor's spear 5 get in the soil under the drive of towed layering spade 3; Upper strata spear 4 is positioned at 15-20cm place under the soil layer, and lower floor's spear 5 is positioned at 15-20cm place under the soil layer that upper strata spear 4 streaks, like this each spear the soil layer of dark pine at 15-20cm; And whole chiselling layer reaches 30-40cm; Thereby having reached is the purpose that dark loose certain depth can be saved power again, and towed layering spade 3 can produce downward component when burying, and can effectively avoid producing the piece of digging on a large amount of.

Claims

1. a towed layering deep soil loosing shovel comprises holder (2), towed layering spade (3), upper strata spear (4), lower floor's spear (5) and spear set bolt (6), it is characterized in that: said towed layering spade (3) adopts the towed design of sweepback.

2. towed layering deep soil loosing shovel according to claim 1 is characterized in that: on towed layering spade (3), be fixed with upper and lower layer spear.
