Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The anti-blocking seed filling structure of the agricultural precision sowing device shown in the attached drawings 1 and 2 comprises a seed filling sieve 1, an upper baffle 2, a lower baffle 3, a cleaning mechanism 4 and a controller.
Wherein, a bottom plate 11 of the seed filling sieve 1 is provided with a plurality of shaped holes 12 in a square array; the upper baffle plate 2 is arranged on the upper side of the seed filling sieve 1 in an abutting mode and can be driven by a first driving element 5 to slide relative to the seed filling sieve 1; a first groove 21 is formed on the pattern hole 12 corresponding to each row; the lower baffle 3 is mounted against the lower side of the seed filling sieve 1 and can be driven by a second driving element 6 to slide relative to the seed filling sieve 1; a second groove 31 is formed corresponding to each row of the holes 12; the cleaning mechanism 4 is arranged on the upper baffle 2 and used for cleaning the holes 12 on the bottom plate 11 to prevent the holes from being blocked; the controller is connected to the first driving element 5 and the second driving element 6, in this embodiment, the first driving element 5 and the second driving element 6 are both electric push rods.
With the above structure, in an initial state, as shown in fig. 5(a), the upper baffle 2 does not shield the upper ends of any of the holes 12 (the first groove portion 21 is opposite to the holes 1 up and down), and the lower baffle 3 shields the lower ends of all the holes 12 (the second groove portion 31 is staggered with the holes 1), in this state, when the seed filling sieve 1 performs translational vibration, a part of seeds in the seed filling sieve 1 can fall into each hole 12 to fill each hole 12 to complete seed filling; when seed discharging is needed, firstly, the first driving element 5 drives the upper baffle 2 to move, so that the upper baffle 2 shields the upper ends of all the holes 12 (the first groove part 21 and the hole 1 are staggered mutually, and the state is marked as a first state), and the end state is shown in fig. 5 (b); then, the second driving element 6 drives the lower baffle 3 to move, so that the lower baffle 3 releases the shielding of all the holes 12, and the state is as shown in fig. 5(c), at this time, most seeds in each hole 12 can naturally fall down under the action of gravity; finally, the cleaning mechanism 4 acts on all the molded holes 12 to clean the molded holes, so that the seeds clamped in the molded holes 12 fall down, and the state of the cleaning mechanism is as shown in fig. 5(d), thereby ensuring that no seeds are blocked in the molded holes 12 when the seeds are filled next time.
A plurality of groups of cleaning mechanisms 4 are arranged, and a group of cleaning mechanisms 4 is arranged on the bottom plate 11 corresponding to each row of the shaped holes 12; as shown in fig. 3, the cleaning mechanism 4 includes a rotating rod 41, a cleaning sheet 42 and a driving assembly, and the rotating rod 41 can rotate relative to the bottom plate 11; a plurality of cleaning sheets 42 are linearly arranged on the rotating rod 41 in an array manner, and the total number of the cleaning sheets 42 on a single rotating rod 41 is equal to the number of the pattern holes 12 in a row of the pattern holes 12; the drive assembly may drive the rotation rod 41 to rotate.
Specifically, as shown in fig. 3, the driving assembly includes guide rods 43 fixed at both ends of the rotating rod 41, guide wheels 44 are provided at the ends of the guide rods 43, and a guide portion 14 having a guide groove is fixed on the side wall 13 of the seed filling screen 1; the guide wheel 44 always moves in the guide groove, and when the guide wheel 44 moves along the guide groove, the guide groove can force the guide rod 43 to generate angular displacement, and the rotating rod 41 is driven to rotate.
As shown in fig. 5(a), the cleaning sheet 42 is composed of an extending portion 421 and a cleaning portion 422, the cleaning portion 422 is disposed at one end of the extending portion 421, and the cleaning portion 422 is arc-shaped.
Through the structure, when the molded hole 12 needs to be cleaned, only on the basis of the first state, the first driving element 5 is controlled to drive the upper baffle plate 2 to translate for a section, so that the guide wheel 44 can drive the rotating rod 41 to rotate along the guide groove when moving, the cleaning piece 42 on the rotating rod 41 rotates along with the rotation, and the cleaning part 422 on the cleaning piece 42 is embedded into the molded hole 12 to clean the molded hole 12, an executing element does not need to be additionally arranged to drive the rotating rod 41 to rotate, and the hardware cost and the control difficulty can be saved.
Preferably, as shown in fig. 4, the cleaning sheets 42 are all mounted on a transition rod 45, and the transition rod 45 can elastically float relative to the rotating rod 41. In this embodiment, an elastic rubber pad 46 is disposed between the transition rod 45 and the rotating rod 41. The structure can relieve the contradiction between the movement of the rotating rod 41 and the rotation of the cleaning sheet 42, the deformation of the elastic rubber pad 46 can meet the requirement of the change of the relative position between the rotating rod 41 and the cleaning sheet 42, and the structural locking caused by the non-conjunction of the movement displacement of the rotating rod 41 and the rotation angle of the cleaning sheet 42 in the process that the cleaning part 422 of the cleaning sheet 42 enters the shaped hole 21 is prevented.
The invention also provides an anti-blocking seed filling method of the agricultural precision seeding device, which is applied to the controller of the anti-blocking seed filling structure of the agricultural precision seeding device, wherein in an initial state, the states of the cleaning sheet, the bottom plate, the upper baffle plate and the lower baffle plate are shown in the attached figure 5(a), and the method comprises the following steps of S701-S703:
step S701, controlling the first driving element 5 to operate, so that the upper baffle 2 moves for a first displacement, and at this time, the upper baffle 2 shields the upper ends of all the holes 12; the end state is shown in FIG. 5 (b);
step S702, controlling the second driving element 6 to operate, so that the lower baffle 3 moves for a second displacement, and at this time, the lower baffle 3 releases the shielding of the lower ends of all the holes 12; the end state is shown in FIG. 5 (c);
step S703, controlling the first driving element 5 to operate, so that the upper baffle 2 moves to a third displacement, and the cleaning mechanism 4 cleans all the holes 12; the end state is shown in FIG. 5 (d).
