Abstract
The utility model relates to a kind of bionic, drag-reducing deep soil loosing shovel, belongs to soil subsoiling technical field.This deep soil loosing shovel comprises spade and spear; Described spade is interconnected by straight shovel handle and curved shovel handle two parts and forms, described curved shovel handle and spear affixed; The working face that described spear and curved shovel handle contact with soil is in use the parabolic cylinder of bionical shape; The both sides of described spear and curved shovel handle are respectively equipped with a shovel wing, described shovel wing working face in use and described cylindrical parabolic shape basically identical, the described shovel wing and spear, curved shovel handle are all affixed.Soil resistance when this deep soil loosing shovel can reduce subsoiling mechanical work also can be saved energy and reduce the cost.
Description
Technical field
The utility model relates to a kind of shovel of soil subsoiling operation, belongs to soil subsoiling technical field.
Background technology
Soil subsoiling is a kind of widely used conservation tillage method in recent years, and object is to break hard tillage pan in farmland, thus deepens the plow layer degree of depth, increase the ventilative of soil and water penetration and play effects such as improving crop root growth environment.Research shows, deep-ploughing implement can increase considerably the output of crop, the output of especially dark root system crop, is an important yield-increasing technology.
Status along with Subsoiler becomes further important in agricultural tillage field, how to reduce tillage resistance when subsoiling class mechanical work and to reduce facility power consumption to have become hot issue urgently to be resolved hurrily.Deep soil loosing shovel is one of parts of subsoiler most critical, affects the effect of deep-ploughing implement to a great extent.In this research field, the structure and parameters of Chinese scholars most attention appropriate design deep soil loosing shovel, makes it have good transaction capabilities and reliability, under the quality prerequisite ensureing Subsoiler, reduces tillage resistance, realizes the object of energy-saving and emission-reduction.Must heal become ripe bionic, drag-reducing technology and the be Research of Drag Reduction of subsoiling component of development in recent years provides a brand-new thinking.
Summary of the invention
The purpose of this utility model is: the defect overcoming above-mentioned prior art, proposes a kind of soil resistance when can reduce subsoiling mechanical work and the Novel bionic deep soil loosing shovel that can save energy and reduce the cost.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of bionic, drag-reducing deep soil loosing shovel, comprises spade and spear; Described spade is interconnected by straight shovel handle and curved shovel handle two parts and forms, described curved shovel handle and spear affixed; The working face that described spear and curved shovel handle contact with soil is in use parabolic cylinder, and the directrix of described parabolic cylinder meets following equation:
In formula, x and y is with the abscissa of the crosspoint of straight shovel handle and the curved shovel handle center line rectangular coordinate system that is initial point and ordinate, and wherein y-axis is along the axis direction of straight shovel handle and the direction pointed to away from spear, and x-axis is perpendicular to y-axis and the direction pointed to away from spear.
Bionic, drag-reducing deep soil loosing shovel of the present utility model adopts bionical shape structure; the matching structure curve shape of certain digging animal pawl toe; relative to the deep soil loosing shovel (comprising cutter type, arrow type and double airfoil type) of traditional form; significantly can reduce soil resistance during farming; thus greatly reduce the energy resource consumption of facility operation; be conducive to energy-saving and emission-reduction, protection of the environment.
Preferably, described spear and curved shovel handle are formed in one formula syndeton.The bonding strength of described spear and curved shovel handle can be increased like this, and its production cost can be reduced.
In order to increase soil loose range, bionic, drag-reducing deep soil loosing shovel of the present utility model also increases by two shovel wings at spear and curved shovel handle both sides, and described shovel wing working face is in use consistent with described cylindrical parabolic shape, and the described shovel wing and spear, curved shovel handle are all affixed.Like this by increasing the structure of the shovel wing, the effect being similar to omnibearing-deep ploughing can be realized.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Embodiment
Embodiment one
As shown in Figure 1, the bionic, drag-reducing deep soil loosing shovel of the present embodiment, comprises spade 1 and spear 2; Spade 1 is interconnected by straight shovel handle 1-1 and curved shovel handle 1-2 two parts and forms, curved shovel handle 1-2 and spear 2 affixed; The working face that spear 2 and curved shovel handle 1-2 contact with soil is in use parabolic cylinder 3, and the directrix of parabolic cylinder 3 meets following equation:
As shown in fig. 1, in formula, x and y is with the abscissa of the crosspoint of straight shovel handle and the curved shovel handle center line rectangular coordinate system that is initial point and ordinate, wherein y-axis along straight shovel handle axis direction and point to away from the direction of spear, x-axis is perpendicular to y-axis and the direction pointed to away from spear.
According to above formula, the parabolic cylinder 3 of the present embodiment is divided into three sections, and first paragraph is the first half of curved shovel handle 1-2, and second segment is the latter half of curved shovel handle 1-2, and the 3rd section is spear 2, forms perfect biomimetic features.
In the present embodiment, spade and spear can be formed in one formula syndeton, can certainly be the affixed structure of split.
The bionic, drag-reducing deep soil loosing shovel of the present embodiment adopts bionical shape structure; the matching structure curve shape of certain digging animal pawl toe; relative to the deep soil loosing shovel (comprising cutter type, arrow type and double airfoil type) of traditional form; significantly can reduce soil resistance during farming; thus greatly reduce the energy resource consumption of facility operation; be conducive to energy-saving and emission-reduction, protection of the environment.
Embodiment two
The present embodiment is the improvement on embodiment one basis, its improvements are: in order to increase soil loose range, the present embodiment increases by two shovel wings at spear 2 and curved shovel handle 1-2 both sides, shovel wing working face is in use basically identical with parabolic cylinder 3 shape, shovels the wing and spear 2, curved shovel handle 1-2 is all affixed.The working face of the shovel wing can keep sustained height with parabolic cylinder 3, also can lower than parabolic cylinder 3 suitably distance, and distance preferably defines between 3-10cm.
The utility model is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
