Abstract
The utility model relates to an agricultural seeding machine, in particular to a profile ditching device of a seeding machine. Technical scheme contains a main frame of seeding machine (8), a furrow opener & profiling four-bar mechanism (6) and a spring (2). The four edges of the profiling four-bar mechanism are connected via four hinges, wherein one edge is fastened to the main frame of the seeding machine, and the other edge of the profiling four-bar mechanism is connected with the furrow opener. The spring (2) is mounted between the main frame of the seeding machine (8) and the furrow opener. A tractor pulls the main frame of the seeding machine to move ahead. Because the four edges of the profiling four-bar mechanism are connected together through a hinge, wherein one edge connected with the furrow opener may move up and down according to the rugged road level, when the ground is not rugged. The spring is for assurance of balance of pressure. The furrow opener can ditch the furrow with equivalent depth according to ground conditions. The utility model is characterized in rational structure, convenient operation and automatic profiling ditching. After ditching, seeding and fertilizing can be performed. In this way, seedling emergence rate can be guaranteed.
Description
Affiliated technical field:
The utility model relates to a kind of profiling trench digging device of agricultural seeder machinery, particularly sower.
Background technology:
At present, in agricultural production, people often use multiplerow seeder to carry out operation, trench digging, sowing, fertilising or the like; Because the plough and the sower body frame of existing sower are fixed together, can not mediate according to the height depth on ground, if ground is not too smooth, the ditch of leaving have have deeply shallow, seeding and fertilizing subsequently also be have have deeply shallow, be unfavorable for the seed normal growth, influence emergence rate, cause damage to agricultural production.
The utility model content:
The utility model purpose provides a kind of profiling trench digging device of sower, can be according to the formation state on ground, and plough is left the identical ditch of the degree of depth, guarantees emergence rate, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the profiling trench digging device of sower is formed and is comprised sower body frame, plough, profiling quadric chain, spring, four limits of profiling quadric chain link together by four hinges, fixedly connected with the sower body frame in one of them limit, corresponding another limit is connected with plough on the profiling quadric chain, is provided with spring between sower body frame and plough.
Many group the utility model can be set on the sower, realize the multirow operation, for example two row, triplex row, four lines or the like.
Two ploughs can be set, link together by connecting rod, the afterbody of connecting rod is provided with land wheel.Two ploughs mate mutually with kind of tank tower and fertile tank tower respectively.Spring is arranged between the extension rod and plough connecting rod of sower body frame by pillar.
In order to guarantee the stability of profiling quadric chain, between plough connecting rod and profiling quadric chain, also be provided with support bar.
Adopt the utility model, tractor-drawn sower body frame advances, when being uneven appears in ground, because four limits of profiling quadric chain are connected through the hinge, the limit that is connected with plough can be uneven to do automatically and move up and down with landing ground, spring guarantees the balance of pressure, and plough is left the same ditch of the degree of depth automatically according to state of ground, realizes the automatic profiling trench digging.
The utlity model has characteristics such as rational in infrastructure, easy to use, automatic profiling trench digging, can leave the same ditch of the degree of depth automatically, carry out seeding and fertilizing subsequently, guarantee emergence rate, increase work efficiency according to being uneven of ground.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram.
Among the figure: land wheel 1, spring 2, pillar 3 is planted tank tower 4, preceding plough 5, profiling quadric chain 6, fertile tank tower 7, sower body frame 8, post-trenching device 9, hinge 10, connecting rod 11, support bar 12, extension rod 13.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the profiling trench digging device of sower is formed and is comprised sower body frame 8, plough, profiling quadric chain 6, spring 2, four limits of profiling quadric chain link together by four hinges 10, fixedly connected with sower body frame 8 in one of them limit, corresponding another limit is connected with plough on the profiling quadric chain, is provided with spring 2 between sower body frame and plough.Two ploughs are set, and preceding plough 5 and post-trenching device 9 connect 11 by connecting rod and are connected together, and the afterbody of connecting rod is provided with land wheel 1.Two ploughs 5 and 9 mate mutually with kind of tank tower 4 and fertile tank tower 7 respectively.Spring 2 is arranged between the extension rod 13 and plough connecting rod 11 of sower body frame by pillar 3.In order to guarantee the stability of profiling quadric chain, between plough connecting rod 11 and profiling quadric chain 6, also be provided with support bar 12.Tractor-drawn sower body frame advances, when being uneven appears in ground, because four limits of profiling quadric chain are connected through the hinge, the limit that is connected with plough can be uneven to do automatically and move up and down with landing ground, spring guarantees the balance of pressure, and plough is left the same ditch of the degree of depth according to the state of ground automatic profiling.
