The horizontal adjusting mechanism is characterized in that a one-translation two-rotation parallel mechanism is formed by three different support chains, one static platform and a moving platform, wherein three moving pairs are driving pairs. By means of adjustment for movement of the three moving pairs, adjustment for levelness of a vibration seed plate of the planter is achieved. The horizontal adjusting mechanism has the advantages of being high in mechanism rigidity, strong in bearing capacity, and high in adjusting precision, bringing convenience to users to adjustment of the horizontal position of the planter, and providing conditions to field seedling precision planting.
Description
Technical field
The utility model belongs to the agricultural seeding machine technical field, is specifically related to a kind of field precision planter level(l)ing mechanism of growing seedlings.
Background technology
Sowing is the important technical links in the agricultural production process, along with the high speed development of China's economic society, and the continuous progress of agricultural science and technology, the enforcement of precision agriculture is had higher requirement to seeding quality.Sower is the Main Means of realizing mechanization precise sowing technology, and the quality of its performance directly affects upgrowth situation and the output of seeding quality and crops.The field seedling raising precision planter that the utility model matches is a kind of air-sucking vibration plate type precision seeder, it can overcome the many shortcomings of mechanical type seeding apparatus, the seed physical dimension is required not tight, easily realize the simple grain program request, have the advantages such as operating speed height, seed damage ratio are little.Air-sucking vibration plate type precision seeder is grown seedlings in seeding process in the field, if there is certain angle of inclination in the sower vibration seed tray, the position that can cause having on kind of the dish does not have seed, causes some sucker hole to be inhaled and causes sowing the hole less than seed.Even through the processing before the seedling, also certainly exist the irregular situation of some places, when the walking guide rail of completing in the field is sowed, may there be two inclinations angle in the horizontal direction in the sower vibration seed tray, this just needs a kind of level(l)ing mechanism, the sower vibration seed tray is remained under the level vibrate, guarantee the precise sowing requirement of aspiration vibrating precise sower.
Level(l)ing mechanism of the present utility model is that the three-freedom degree spatial parallel structure is rotated in an a kind of translation two, selects three moving sets secondary as driving, and it can accurately realize the requirement of both direction angular adjustment.Mechanism is in the Level tune process, at first fill the digital display instrument of two angle levels at sower vibration seed tray crossbeam, it can show seeder dish tilt condition, through just can guaranteeing the level of vibration seed tray after converting by the adjusting of level(l)ing mechanism, provide condition for realizing the air suction vibration disc type field precise sowing of growing seedlings.
Summary of the invention
But the purpose of this utility model is the mechanism that a kind of implementation space two-dimensional rotary will be provided, and satisfies the problem that field seedling raising precision planter vibration seed tray keeps level.
The realization the technical solution of the utility model is: the field precision planter level(l)ing mechanism of growing seedlings comprises fixed platform, moving platform and is connected and fixed platform and a translation two one-rotation parallel mechanisms that three side chains of moving platform form, three side chains of a described translation two one-rotation parallel mechanisms are side chain AB, side chain EDC and side chain HGF, the A of side chain AB end links with the fixed platform moving sets with it, and the B end of side chain AB links with the moving platform ball is secondary; Side chain EDC is comprised of side chain ED and side chain DC, and the E end of side chain ED links with the fixed platform moving sets, and the D end of side chain ED links with the D end revolute pair of side chain DC, and the C end of side chain DC is for linking with the moving platform ball is secondary; Side chain HGF is comprised of side chain HG and side chain GF, and the H end of side chain HG links with the fixed platform moving sets, and the G end of side chain HG links with the G end ball pair of side chain GF, and the F end of side chain GF links with the moving platform ball is secondary.The line quadrature of the line of A, E and A, H.The parallel institution installation site: fixed platform is connected with walking chassis, lower end, and moving platform is connected mutually with sower vibration seed tray system chassis, realizes the requirement of sower Level tune during level-off by regulating three moving sets.
The utility model has the advantage of:
(1) this two rotation-translations parallel institution is simple in structure, and its kinematics two loop equations are independently, and input is analytic solutions with output relation.
(2) this mechanism has the advantages such as simple in structure, that rigidity is large, working space is large.
(3) this field precision planter level(l)ing mechanism kinematic accuracy of growing seedlings is high, is easy to control, can realize the requirement of Level tune under the adverse circumstances.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the field of the present utility model precision planter level(l)ing mechanism structural representation of growing seedlings.
Embodiment
As shown in Figure 1, AHE is silent flatform, and BCF is moving platform, and A, E, H are moving sets (P is secondary), and D is revolute pair (R is secondary), and B, C, G, F are ball secondary (S is secondary).
The utility model patent field seedling raising precision planter level-off parallel institution is by fixed platform, moving platform and be connected and fixed platform and three side chain AB, EDC, HGF of moving platform form, the A place of side chain AB links with the fixed platform moving sets, and the B place of side chain AB links with the moving platform ball is secondary; Side chain EDC is comprised of side chain ED and side chain DC, and the E place of side chain ED links with the fixed platform moving sets, and the D place of side chain ED links with side chain DC revolute pair, and the C place of side chain DC links with the moving platform ball is secondary; Side chain HGF is comprised of side chain HG and side chain GF, and the H place of side chain HG links with the fixed platform moving sets, and the G place of side chain HG links with side chain GF ball is secondary, and the F place of side chain GF links with the moving platform ball is secondary.The line quadrature of the line of A, E and A, H.
According to the characteristics of field air-sucking vibration plate type precision seeder vibration seed tray motion, draw sower in the necessity of field work level-off.Analyze the kinetic characteristic of this parallel institution degree of freedom and moving platform, draw this parallel institution and have three degree of freedom, the freely-movable of moving platform be along Z axis movement, around with the rotation of X-axis with around the rotation of Y-axis, can satisfy the requirement of level-off, selected three moving sets secondary as driving.Parallel institution is carried out the positive and negative solution analysis in position drawn the position relationship mathematic(al) representation of Mechanism input and output.During the level-off operation, at first obtain being contained in two angles of the seeder dish heeling condition of the two angle levels number display instrument demonstration on the sower vibration seed tray crossbeam, obtain the values that three mobile driving pairs need adjusting after the position relationship expression formula conversion through Mechanism input and output.Then regulate three and move and drive the requirement that secondary moving displacements reach precision planter vibration seed tray level-off, just can guarantee the level of vibration seed tray by the adjusting of level(l)ing mechanism, provide condition for realizing the air suction vibration disc type field precise sowing of growing seedlings.
This level-off mechanism low price, control is easier to, easy to operate and precision is higher, can realize the requirement of level-off under the adverse circumstances, can also be applied to other level-off occasion.
