Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution:

example (b):

as shown in figures 1-3, a rice transplanting and fertilizing integrated device based on a rice transplanter comprises a rice transplanting hand 1 and a fertilizing device 2 of the rice transplanter;

the bottom of the seedling transplanting hand 1 is inverted V-shaped, two symmetrical through holes 3 are arranged in the seedling transplanting hand 1, and the bottoms of the through holes 3 are communicated with the tip end of the bottom of the seedling transplanting hand 1;

the fertilizing device 2 comprises a fertilizing column 4 and a soil retaining mechanism 5 which are matched with the through hole 3, the soil retaining mechanism 5 is of a cylindrical structure and consists of two semi-cylindrical movable units 6, the two movable units 6 are respectively and rotatably connected to the wall of the same through hole 3, a tapered hole 7 is formed in the soil retaining mechanism 5, the large-diameter end of the tapered hole 7 is close to the rice transplanting hand 1, the soil retaining mechanism 5 is sleeved with a first return spring 8, and two ends of the first return spring 8 are respectively connected with the outer wall of the through hole 3 and the outer wall of the movable unit 6 (the inner diameter of the first return spring 8 is matched with the outer diameter of the soil retaining mechanism 5);

the fertilizing column 4 is arranged in the through hole 3 in a sliding mode, the top end of the fertilizing column 4 is fixedly connected with a link mechanism 9 used for driving a transplanting hand 1 on a rice transplanter, the bottom end of the fertilizing column 4 extends into the tapered hole 7, the outer diameter of the lower end of the fertilizing column 4 is smaller than that of the upper end of the fertilizing column 4, a second return spring 10 is sleeved outside the lower end of the fertilizing column 4, and two ends of the second return spring 10 are connected with the inner wall of the through hole 3 and the outer wall of the fertilizing column 4 respectively; fertilization hole 11 that the inside of fertilization post 4 was equipped with the intercommunication, be provided with the chemical fertilizer in the fertilization hole 11. The device can be used by directly replacing the rice transplanting hand 1 on the existing rice transplanting machine.

The working principle is as follows: when the transplanter plants, the transplanting hand 1 is driven to move to transplant rice (the process is common knowledge in the field and is not described in detail herein), and when the transplanting hand 1 plants, the transplanting hand contacts with the soil and moves upwards along the fertilizing column 4 under the damping action of the soil. Relatively, fertilization post 4 stretches into to in the bell mouth 7, along with the stretching into bell mouth 7 of fertilization post 4 is strutted, two movable unit 6 are strutted, and then with fertilization hole 11 and outside intercommunication, the fertilizer in the fertilization hole 11 falls into soil along with it. After the rice transplanting is finished, the rice transplanting hand 1 is pulled out, in the process, the two movable units 6 are reset under the action of the first return spring 8 and the second return spring 10, and the rice transplanting hand 1 is reset. Repeating the above actions when transplanting next time, and circularly finishing fertilization. The fertilizer is applied in the process of transplanting rice seedlings, the rice transplanting holes are the fertilizer applying holes 11, the process of ditching is avoided, and the energy required by ditching is saved.

In order to ensure the inserting effect of the rice transplanting hand 1, the upper end of the conical hole 7 is provided with a transition hole matched with the fertilizing column 4. So can guarantee when transplanting rice seedlings hand 1 inserts soil, the transition hole is advanced gone into to fertilization post 4, fertilization post 4 compression second reset spring 10 this moment, the reaction of second reset spring 10 is done and then continues to promote on 3 inner walls of through-hole and keep off soil mechanism 5 and stretch into soil, when fertilization post 4 gets into bell mouth 7, movable unit 6 just is strutted gradually, reach the effect of breaking soil earlier and fertilizeing again, can effectively avoid soil to get into between two movable unit 6.

The utility model discloses a device makes the fertilization process go on simultaneously with transplanting rice seedlings, has cancelled the process that present earlier division of slot fertilizies again, and is energy-conserving laborsaving, can guarantee that the chemical fertilizer of exerting is close to the seedling root, has effectively guaranteed the degree of accuracy of fertilization, and the process of breaking soil of transplanting rice seedlings simultaneously does not have earth and gets into between two movable unit 6, has effectively guaranteed the permanence of fertilization, has overcome the easy shortcoming that is blockked up by soil of fertilizer injection unit 2.

Further, as shown in fig. 1, the bottom of the soil guard mechanism 5 is a cone structure. The soil breaking effect is better.

Further, as shown in fig. 5 and 6, a horizontal first connecting hole 12 is formed in the side wall of the rice transplanting hand 1, the first connecting hole 12 is communicated with the through hole 3, a horizontal second connecting hole 13 is formed in the upper portion of the fertilizing column 4, the second connecting hole 13 is communicated with the fertilizing hole 11, and the first connecting hole 12 is arranged below the second connecting hole 13; the end of the first connecting hole 12, which is far away from the second connecting hole 13, is connected with a feeding pipe 14, and the feeding pipe 14 is connected with a fertilizer storage tank (the fertilizer storage tank can be fixed on the rice transplanter).

When the rice transplanting is finished, when the mechanisms reset, the first connecting holes 12 are disconnected with the second connecting holes 13, then a channel for fertilizer to enter is closed, and the fertilizer can be prevented from falling to cause waste. The first connecting hole 12 and the second connecting hole 13 that set up can guarantee that the fertilization volume is the same at every turn, and can avoid fertilizer to drop and cause the waste.

Further, as shown in fig. 3 and 4, a vertical connecting groove 15 is formed in the hole wall of the through hole 3, a connecting plate 16 is arranged at the top of the movable unit 6, a horizontal connecting shaft 17 is fixedly arranged at the top of the connecting plate 16, and the connecting shaft 17 is rotatably connected with the connecting groove 15. (the opposite two side walls of the connecting groove 15 are provided with rotating holes, and the connecting shaft 17 is rotatably connected with the connecting groove 15 through the rotating holes). the movable unit 6 is connected with the rice transplanting hand 1 in such a way, and when the movable unit 6 is spread, the top of the movable unit 6 and the rotating shaft rotate around the axis of the rotating shaft together; when the movable units 6 are not stressed, the two movable units 6 can not rotate towards the relatively close direction due to the limiting effect of the groove bottom of the connecting groove 15 on the connecting plate 16, so that the stability of the movable units 6 is ensured, and the movable units 6 are ensured to be spread only under the action of the fertilizing column 4 and do not rotate randomly along with the movement of the seedling transplanting hand 1.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
