Because the rack 8 can only move transversely due to the limit of the sliding rail 14, and two ends of the sliding rail 14 are respectively hinged with the first hinging lug 28 and the second hinging lug 29, the transplanting arm 2 can drive the rack 8 to move transversely back and forth after being lifted, so as to drive the gear 7 to rotate, the connecting rod 9 is horizontal when the transplanting arm 2 is at the highest point, the upper end of the thin rope 13 is wound on the wire reel 10 and tightened, the two second steel balls 12 are mutually far away under the action of the two supporting ropes 26, the lower end of the piston 5 props against the limit inner ring 18, and the thick rope 6 is loosened.
A fertilizing method of a synchronous side deep fertilizing mechanism used for the combination of mechanical rice seedling transplanting comprises the following steps:
s1, injecting enough fertilizer into a storage box before transplanting rice, then manually controlling a rice transplanter body 1 to start transplanting rice, enabling a rice transplanting arm 2 to descend to insert rice seedlings into soil, enabling the rice transplanting arm 2, a connecting rod 9, a rack 8 and a gear 7 to interact with each other, driving a wire reel 10 on the gear 7 to rotate and loosening a thin rope 13, enabling two second steel balls 12 to approach each other, enabling a piston 5 to move upwards relative to an injection pipe in the descending process of the injection pipe, gradually enabling a main pipe 3 to be communicated with a branch pipe 4, and enabling the fertilizer in the branch pipe 4 to enter the main pipe 3;
s2, the seedling transplanting arm 2 descends to insert seedlings into soil, the thin rope 13 is completely loosened, the piston 5 moves to the highest point relative to the main pipe 3, the first steel ball 11 can move to the position above the two second steel balls 12, then the seedling transplanting arm 2 loosens the seedlings to rise back, the thin rope 13 gradually moves to a tight state when the seedlings rise back initially, the first steel ball 11 is still clamped by the two second steel balls 12, and the thick rope 6 is loosened quickly;
s3, the transplanting arm 2 continues to rise, the two second steel balls 12 are far away from each other and no longer limit the first steel ball 11, the piston 5 rapidly slides downwards under the action of the first spring 20 and pushes against the limit inner ring 18 due to the fact that the thick rope 6 is loosened by a sufficient distance, so that the fertilizer in the main pipe 3 is rapidly pushed to the seedling inserting position to complete fertilization, and then the transplanting arm 2 continues to rise back until next transplanting operation is performed.
The working principle is as follows: the working principle is as follows: in the initial state, the thin rope 13 is in a stretched state, at the moment, the two first steel balls 11 are pulled by the thin rope 13 to be in a state of being away from each other, and the thick rope 6 in the initial state is in a loose state;
in the descending process of the transplanting arm 2, after the piston 5 descends for a certain distance along with the transplanting arm 2, the thick rope 6 is changed from a loose state to a tight state, at the moment, the piston 5 cannot descend, then along with the continuous descending of the transplanting arm 2, the joint of the main pipe 3 and the branch pipe 4 is opened, so that fertilizer enters the main pipe 3, the thin rope 13 can be gradually unreeled along with the rotation of the wire reel 10 in the whole process, so that the distance between the two second steel balls 12 is gradually reduced, a door closing effect is formed until the two second steel balls 12 are close to a limit state, after the door is closed, the first steel ball 11 is forced to ascend through the space between the two second steel balls 12 under the tensile force of the thick rope 6, and after the door is closed, the transplanting arm 2 continues to descend for a certain distance, so that the thin rope 13 is turned into a loose state;
then, in the process of ascending the transplanting arm 2, the gear 7 reversely rotates along with the reverse translation of the rack 8, so that the wire reel 10 winds the thin rope 13, the thin rope 13 gradually changes from slack to tight again (the two second steel balls 12 are pulled back to form a door opening effect), meanwhile, the thick rope 6 also changes from a tight state to a loose state, but the two second steel balls 12 are not opened at the moment (the thin rope 13 needs a certain time from the loose state to the tight state), and the first steel balls 11 cannot prop the two second steel balls 12 open under the elastic force of the first spring 20, so that the first steel balls 11 cannot be directly popped downwards, when the transplanting arm 2 continuously ascends, the thick rope 6 is completely loosened (a downward stroke is reserved for the piston 5), the thin rope 13 tightly pulls the two second steel balls 12, the two second steel balls 12 completely open the door and can be passed by the first steel balls 11, and at the piston 5 pulls the loosened thick rope 6 downwards to impact and rush out fertilizer under the elastic force of the first spring 20;
in the process of descending the transplanting arm 2, the thick rope 6 goes through two processes, wherein the first process is from loosening to just tightening, the two second steel balls 12 do not start to enter a door closing state in the process, and the piston 5 also descends along with the transplanting arm 2;
the second process is from just tightening to pulling more tightly (namely the compression amount of the first spring 20 is larger), the piston 5 can not continuously descend in the process, so that the two second steel balls 12 can continuously descend along with the seedling transplanting arm 2 until the closing process is completed, and when the seedling transplanting arm 2 descends to the lowest point, the first steel balls 11 are just positioned above the two second steel balls 12 and are intercepted;
in the process that the transplanting arm 2 moves upwards, the thick rope 6 is changed from tension to slack, the slack of the thick rope 6 can meet the stroke requirement of the piston 5 along with the fact that the transplanting arm 2 continues to move upwards for a certain distance, and then at the moment when the thin rope 13 pulls the two second steel balls 12 to completely open the door, the piston 5 can carry the slack thick rope 6 and the first steel balls 11 to rush downwards together under the action of the first spring 20;
during the repeated transplanting of the transplanting arms 2, the piston 5 also repeats the above process, thereby performing the fertilizing operation for each transplanted seedling.
The above examples only show one or more embodiments of the present invention, and the description is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
