DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 5 As shown, it is a structural diagram of a seeder for maintaining the original surface layer of soil provided by an embodiment of the present invention, comprising a machine body 1, an angle adjustment unit 100, a directional feeding unit 200, a crushing unit 300, a feeding system 400 and an anti-blocking unit 500, wherein a longitudinal frame 2 and a longitudinal frame 3 are installed at the bottom end of the machine body 1, and the angle adjustment unit 100 is provided with two groups, which are respectively hinged on the longitudinal frame 2 and the longitudinal frame 3; the directional feeding unit 200 is installed on the longitudinal frame 2 and the longitudinal frame 3, and the directional feeding unit 200 is located between the angle adjustment units 100 on both sides; the crushing unit 300 is rotatably installed at the bottom ends of the longitudinal frames 1 and 2 and 3; the feeding system 400 is installed in the machine body 1, and fertilizers and seeds are stored in the machine body 1 respectively; the anti-blocking unit 500 is arranged at the top ends of the longitudinal frames 1 and 2 and 3, and the working end of the anti-blocking unit 500 contacts the feeding system 400 when rotating.

[0040] In one example of the present invention, the machine body 1 is arranged on an external walking mechanism so that the seeder as a whole can move in the field.

[0041] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the angle adjustment unit 100 includes a scraper 4, a feeding plate 5, a telescopic member 1 6, a telescopic member 2 7, a limiting column 8 and a limiting groove 9;

[0042] The scraper 4 is hinged on the longitudinal frame 1 2, and the feed plate 5 is hinged on the longitudinal frame 2 3;

[0043] The telescopic member 1 6 and the telescopic member 2 7 are respectively installed at the bottom of both ends of the body 1, and limit columns 8 are installed on the telescopic member 1 6 and the telescopic member 2 7. The limit columns 8 on both sides are respectively slidably connected with the limit grooves 9 opened on the sides of the scraper 4 and the feeding plate 5.

[0044] In one example of the present invention, the telescopic member 1 6 and the telescopic member 2 7 described in the present application can be used in actual use by linear drive devices such as air cylinders, hydraulic cylinders, electric cylinders and electric telescopic rods. The elongation of the telescopic member 1 6 and the telescopic member 2 7 can be controlled respectively, so that the telescopic member 1 6 and the telescopic member 2 7 can respectively pull the scraper 4 to swing along the longitudinal frame 1 2, the feed plate 5 to swing along the longitudinal frame 2 3, and the limit column 8 slides along the limit groove 9.

[0045] like Figure 1 As shown, as another preferred embodiment of the present invention, the directional feeding unit 200 includes a rotating shaft 10, a roller shaft 11, a conveyor belt 12, a fixing plate 13 and a fixing rod 14;

[0046] The rotating shaft 10 is rotatably mounted on the longitudinal frame 1 2 and the longitudinal frame 2 3, and rollers 11 are mounted on the rotating shaft 10 on both sides, and adjacent rollers 11 are connected by a conveyor belt 12;

[0047] A fixing rod 14 is installed on one side of the longitudinal frame 1 2 and the longitudinal frame 2 3 opposite to each other, and the fixing rod 14 is connected to a fixing plate 13 arranged on the inner side of the conveyor belt 12 .

[0048] In one example of the present invention, the rotating shaft 10 is driven by an external motor. When the rotating shaft 10 rotates along the longitudinal frame 1 2 or the longitudinal frame 2 3, the rotating shaft 10 drives the roller 11 at the corresponding position to rotate synchronously, and then drives the conveyor belt 12 to move synchronously, so as to transport the soil layer that moves to the top of the scraper 4 and falls on the feeding plate 5 when it moves to the highest point. In addition, the soil layer is supported by the arranged fixed plate 13.

[0049] like Figure 1 As shown, as another preferred embodiment of the present invention, the crushing unit 300 includes a second rotating shaft 15, a first crushing frame 16 and a second crushing frame 17;

[0050] The bottom ends of the longitudinal frame 1 2 and the longitudinal frame 2 3 are both equipped with a rotating shaft 2 15;

[0051] A crushing frame 16 is installed on the rotating shaft 2 15 at the bottom end of the longitudinal frame 1 2 , and a crushing frame 2 17 is installed on the rotating shaft 2 15 at the bottom end of the longitudinal frame 2 3 .

[0052] In one example of the present invention, when the rotating shaft 10 rotates, the rotating shaft 15 at the bottom ends of the longitudinal frame 2 and the longitudinal frame 3 rotate synchronously, and the rotating shaft 15 drives the crushing frame 16 and the crushing frame 17 at the corresponding positions to rotate, wherein the crushing frame 16 is used to crush the hard soil layer to make it loose, and the crushing frame 17 stirs the soil, seeds and fertilizers so that the seeds and fertilizers fall into the loose soil to facilitate the growth of plant seeds.

[0053] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the feeding system 400 includes a partition 18, a movable plate 19, a top plate 20, a feed pipe 1 21, a feed pipe 22 and a discharge rack 23;

[0054] The partition 18 is fixedly installed inside the machine body 1, and movable plates 19 are hinged on both sides of the partition 18. Seeds and fertilizers are stored on both sides of the partition 18 respectively;

[0055] A top plate 20 is hingedly connected to the top of the body 1;

[0056] The feeding pipe 1 21 and the feeding pipe 2 22 are respectively installed on the movable plates 19 at both sides. A discharging rack 23 is arranged obliquely at the bottom end of the feeding pipe 1 21 and the feeding pipe 22 , and a discharging hole is arranged at the bottom of the discharging rack 23 .

[0057] In one embodiment of the present invention, when the body 1 moves, the seeds and fertilizers move along the surface of the movable plate 19, and when they move to the lowest point, they move along the feed pipe 1 21 and the feed pipe 2 22 respectively, and fall under the action of gravity, and are finally discharged outward from the bottom of the discharge rack 23 and fall on the loose soil surface.

[0058] like Figure 4 As shown, as another preferred embodiment of the present invention, the anti-blocking unit 500 includes a rotating shaft 3 24 and a rubber rod 25;

[0059] The top ends of the longitudinal frame 1 2 and the longitudinal frame 2 3 are both rotatably mounted with a rotating shaft 3 24 in the machine body 1, and a rubber rod 25 is fixedly mounted on the shaft end of the rotating shaft 3 24;

[0060] The rubber rod 25 applies force to the seeds and fertilizers stored in the machine body 1 during the rotation process along with the rotating shaft 3 24 .

[0061] In one embodiment of the present invention, when the rotating shaft three 24 rotates along the longitudinal frame one 2 and the longitudinal frame two 3, the rotating shaft three 24 drives the rubber rod 25 at the shaft end to move synchronously. Since the rubber rod 25 is made of rubber material, motion interference can be avoided during the contact between the rubber rod 25 and the movable plate 19.

[0062] like Figure 1 and 5 As shown, as another preferred embodiment of the present invention, the longitudinal frame 1 2 and the longitudinal frame 2 3 are rotatably mounted with a third shaft 24, a first shaft 10 and a second shaft 15 in sequence along the height direction;

[0063] The rotating shaft 10 is provided with a double-track pulley 26 in the longitudinal frame 1 2 and the longitudinal frame 2 3, and the rotating shaft 2 15 and the rotating shaft 3 24 are provided with a single-track pulley 27 in the longitudinal frame 1 2 and the longitudinal frame 2 3;

[0064] The double-track pulley 26 is connected to the staggered single-track pulley 27 via a synchronous belt 28 .

[0065] In one example of the present invention, the rotating shaft 10 drives the double-track pulley 26 at the corresponding position to rotate when it rotates. The double-track pulley 26 drives the rotating shaft 2 15 to rotate on the one hand, and drives the rotating shaft 3 24 to rotate on the other hand through the arranged single-track pulley 27 and synchronous belt 28, thereby realizing the transmission work of the rotating shaft 10, the rotating shaft 2 15 and the rotating shaft 3 24.

[0066] To sum up, when the seeder is moving in the field, the telescopic member 6 works to pull the scraper 4 set at the bottom to swing along the longitudinal frame 2, so that the scraper 4 is in an inclined state, so as to shovel up the soil layer, and the soil layer moves upward along the surface of the scraper 4. At the same time, the external motor drives the rotating shaft 10 on the longitudinal frame 2 to rotate, and the rotating shaft 10 drives the roller 11 at the corresponding position to rotate synchronously, thereby driving the conveyor belt 12 to move along the fixed plate 13 to transport the shoveled soil layer upward. At this time, the rotating shaft 10 on the longitudinal frame 2 also drives the rotating shaft 2 15 at the bottom to rotate through the monorail pulley 27 and the synchronous belt 28. The rotating shaft 2 15 drives the crushing frame 16 at this position to rotate synchronously to crush the hard soil layer under the scraper 4. The seeds and fertilizers flow out of the body 1, move along the conveying pipe 1 21 and the conveying pipe 2 22, and finally are scattered on the loose soil surface through the discharging frame 23. The rotating shaft 10 also drives the roller 11 at the corresponding position to rotate synchronously through the monorail pulley 27 and the synchronous belt 28. 28 drives the rotating shaft 3 24 and the rubber rod 25 to rotate, and the rubber rod 25 hits the movable plate 19 to prevent fertilizers or seeds from piling up in one place. When the seeder continues to move, the rotating shaft 10 drives the crushing frame 2 17 at the bottom to rotate, and the shallow soil, seeds and fertilizers are mixed together to provide a suitable environment for the growth of seeds. Finally, the complete soil layer shoveled up moves to the top of the conveyor belt 12 and falls on the feeding plate 5, and moves downwardly under the action of gravity, so that it is completely spread on the shallow soil surface after sowing; the seeder can not only shovel up the soil layer and transfer the soil layer during the movement of the seeder through the scraper 4, conveyor belt 12 and feeding plate 5, so as to maintain the integrity of the original surface of the soil, but also can crush the shallow soil layer to make it in a loose state, which is convenient for applying fertilizers and seeds, and effectively mixing them together to provide a suitable growth environment for seeds, which can effectively improve the survival rate and growth state of seeds.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
