Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combined with reference Figure 1-Figure 4The utility model provides an intermittent fertilizer spreading mechanism for agricultural machinery, including a fertilizer bin 1. The fertilizer bin 1 in the utility model can be used on a mobile agricultural equipment, preferably a rotary tillage equipment, so that fertilizer can be directly spread on the soil improved by rotary tillage. The fertilizer bin 1 is a hollow structure, the top is a feeding port, the bottom is a feeding port, the bottom of the fertilizer bin 1 is fixedly connected with a dividing plate 2, the bottom of the dividing plate 2 is provided with a dividing plate 2 3, the dividing plate 1 2 and the dividing plate 2 3 are both provided with a broadcasting port 4 of the same specification, and the broadcasting port 4 can be used for broadcasting fertilizer The granular fertilizer in the bin 1 is fixedly connected to a top ring block 5 at one end of a dividing plate 23, and elastic telescopic components 6 are provided on the dividing plate 12 and the dividing plate 23. A stirring member is rotatably connected in the fertilizer bin 1, and the stirring member can be used to stir the fertilizer in the fertilizer bin 1. By improving the surging property of the fertilizer feeding, the continuity of the fertilizer feeding can be improved. A gear 8 is provided at one end of the stirring member, and the gear 8 is located on one side of the fertilizer bin 1. A rotation drive unit 9 is provided on the outer surface of the fertilizer bin 1. The rotation drive unit 9 is used to engage the gear 18 to rotate and at the same time be in sliding contact with the top ring block 5.

[0024] The top of the fertilizer bin 1 is rotatably connected to a bin cover 10 via a hinge. The bin cover 10 is provided with a handle 11. The bin cover 10 cooperates with the handle 11 to facilitate opening and closing the top of the fertilizer bin 1.

[0025] There are multiple groups of feeding openings 4 on the dividing plate 1 2 and the dividing plate 2 3, and the feeding openings 4 on the dividing plate 1 2 and the feeding openings 4 on the dividing plate 2 3 are on the same straight line. When the feeding openings 4 on the dividing plate 1 2 and the feeding openings 4 on the dividing plate 2 3 overlap, the fertilizer in the fertilizer bin 1 can be spread through the top feeding openings 4 and the bottom feeding openings 4 in turn.

[0026] There are at least four groups of elastic telescopic components 6, and they are distributed in pairs on both sides of the dividing plate 23. The elastic telescopic components 6 include a fixed block 1 61 fixedly connected to the dividing plate 23, a fixed block 2 62 fixedly connected to the dividing plate 2, a T-shaped guide slide rod 63 fixedly connected to the fixed block 1 61, and a reset spring 64 sleeved on the T-shaped guide slide rod 63. The T-shaped guide slide rod 63 arranged on the fixed block 1 61 penetrates and is slidably connected to the fixed block 2 62. When the dividing plate 23 is pushed by the top ring block 5, the T-shaped guide slide rod 63 slides on the fixed block 2 62 to provide a horizontal guiding effect for the dividing plate 23. At this time, the reset spring 64 can be compressed, and the reset spring 64 can be elastically reset to enable the dividing plate 23 to achieve position reset.

[0027] The stirring member includes an auger shaft 7. In the present invention, the stirring member may also be a stirring frame, which can facilitate stirring of the granular fertilizer in the fertilizer bin 1 to improve the fluidity of the fertilizer, thereby improving the smoothness of material discharge.

[0028] A buffer damping pad 13 is fixedly connected to one side of the fixed block 62, and a T-shaped guide slide rod 63 arranged on the fixed block 61 passes through and is slidably connected to the buffer damping pad 13. The buffer damping pad 13 is arranged so that when the reset spring 64 rebounds after being compressed, the end of the T-shaped guide slide rod 63 can act on the end surface of the buffer damping pad 13. By relieving the force of the moving T-shaped guide slide rod 63, the rebound jump of the reset spring 64 can be suppressed, thereby ensuring the stability of the reset of the dividing plate 2 3.

[0029] The rotary drive unit 9 includes a servo motor 91 fixedly mounted on the fertilizer bin 1, a transmission rod 92 fixedly connected to the output end of the servo motor 91, a rotating seat 93 fixedly connected to the fertilizer bin 1, a gear 2 94 fixedly connected to the outer surface of the transmission rod 92, and a round head top block 95 fixedly connected to the bottom end of the transmission rod 92. The transmission rod 92 is rotatably connected to the rotating seat 93, the gear 2 94 is meshed with the gear 1 8, and the round head top block 95 is in sliding contact with the top ring block 5. In the utility model, the servo motor 91 can continue to be controlled by the drive controller, and the servo motor 91 can continue to adjust the speed.

[0030] A mounting base 12 is fixedly connected to the fertilizer bin 1 , and the servo motor 91 is fixedly connected to the mounting base 12 .

[0031] Specifically, by starting the servo motor 91, it can drive the round head top block 95 to rotate through the transmission rod 92. When the end of the round head top block 95 contacts the top ring block 5 once, the top ring block 5 can pass through the dividing plate 2 3. When the elastic telescopic component 6 provides linear guidance and elastic reset for the dividing plate 2 3 at the bottom of the dividing plate 2, the dividing plate 2 3 can make a linear reciprocating motion at the bottom of the dividing plate 2. The dividing plate 2 3 continuously performs reciprocating motion, so that the broadcasting port 4 at the bottom can intermittently overlap and dock with the broadcasting port 4 at the top, so that the fertilizer in the fertilizer bin 1 can be intermittently discharged; at the same time, the rotation of the transmission rod 92 can drive the gear 1 8 to rotate through the gear 2 94, so that the auger shaft 7 located in the fertilizer bin 1 can rotate to stir the granular fertilizer. By promoting the surge of the fertilizer, the smoothness of the fertilizer discharge through the broadcasting port 4 can be guaranteed.

[0032] In addition, when the driving control of the servo motor 91 is stopped, when the sowing port 4 at the bottom may not overlap with the sowing port 4 at the top, the feeding of the fertilizer in the fertilizer bin 1 can be stopped; if you want to adjust the feeding speed of the fertilizer, you can adjust the frequency of the intermittent movement of the dividing plate 2 3 by adjusting the speed of the servo motor 91.
