Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a structure of a seed drill that uses a fan to blow fertilizer. Background Art

[0002] A seeder is a planting machine that sows crop seeds into the soil. According to the sowing method, it can be classified into broadcast seeders, row sowing types, hole sowing types, precision types and combined types. Therefore, there are many types of seeders. When sowing is needed, different seeders can be selected according to the type of crop. When the seeder completes the main sowing task, it also has a variety of auxiliary devices, such as auxiliary machinery for adjusting the sowing spacing and auxiliary machinery for applying fertilizers.

[0003] In the existing fertilizer application auxiliary machinery of the seed drill, wind power is used to blow fertilizer into the fertilizer knife to fertilize the soil. However, when the wind blows, the fertilizer enters the distribution box first, causing the fertilizer to accumulate in the distribution box and hinder the wind power. In addition, the feed port needs to be closed when the wind blows to prevent the wind from being too strong, which makes it difficult for the fertilizer to enter the distribution box.

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Please refer to 1-4, an embodiment of the present invention provides: a structure of a seeding machine using a fan to blow fertilizer, comprising a fan 1, a hose 2 fixedly connected to the air inlet of the fan 1, a wind regulating mechanism 3 fixedly provided between the hose 2 and the air inlet of the fan 1, a pipe connecting sleeve 4 fixedly connected to the air outlet of the fan 1, a fertilizer distribution pipe 5 fixedly connected to both sides of the pipe connecting sleeve 4, a feed port 6 being provided on the upper surface of the fertilizer distribution pipe 5, a discharge port being provided on the lower surface of the fertilizer distribution pipe 5, and the discharge port being connected to the air outlet through a pipe. The fertilizer knife and the fertilizer distribution pipe 5 are provided with a blanking structure 7. The fertilizer enters the fertilizer distribution pipe 5 from the feed port 6. The wind force generated by the fan 1 is used to drive the blanking structure 7 so that the blanking structure 7 regularly strikes and punctures the feed port 6, causing the feed port 6 to be opened repeatedly, thereby allowing the fertilizer to enter the fertilizer distribution pipe 5. The fertilizer is stirred by the blanking structure 7 in the fertilizer distribution pipe 5, effectively preventing blockage. The wind force will transport the fertilizer from the discharge port to the fertilizer knife to achieve the fertilization effect.

[0018] The wind force regulating mechanism 3 includes a baffle 31, which is located inside the pipe at the air inlet of the fan 1. The baffle 31 is fixedly connected to the rotating rod 32 by bolts. The rotating rod 32 passes through the pipe. A rotating handle 33 is fixed on one side of the rotating rod 32. A fixed bracket 34 is provided on the pipe at the air inlet of the fan 1. The rotating rod 32 passes through the fixed bracket 34. Rotating the rotating handle 33 drives the rotating rod 32 to rotate, so that the baffle 31 blocks the channel inside the pipe and hinders the size of the air outlet, thereby realizing the adjustment of the wind force. During the rotation of the rotating handle 33, the fixed bracket 34 and the nut are used to fix the position of the baffle 31.

[0019] The blanking structure 7 includes a rotating roller 71, which is rotatably connected to the fertilizer distribution pipe 5. The fan blades 72 and the lifting block 73 are fixedly connected to the rotating roller 71. The inside of the fertilizer distribution pipe 5 is fixedly connected to the limiting rod 74, which passes through the lifting block 73. When the wind blows towards the fan blades 72, the rotating roller 71 is driven to rotate as a whole in the fertilizer distribution pipe 5, thereby stirring and beating the fertilizer to prevent the fertilizer from being blocked. When the rotating roller 71 rotates, the lifting block 73 performs reciprocating linear motion and moves up and down to pierce and lift the feed port 6, thereby transporting the fertilizer inside the feed port 6 to the fertilizer distribution pipe 5.

[0020] The fan blades 72 face the air outlet of the fan 1 to provide sufficient wind force, and the lifting block 73 faces the feed port 6 so that the lifting block 73 can effectively lift the feed port 6.

[0021] At the position of the feed port 6, a rubber blocking petal is fixedly connected inside the fertilizer distribution pipe 5. The rubber blocking petal is a circular rubber structure composed of multiple rubber petals. When the wind blows, the fertilizer above the feed port 6 squeezes the rubber blocking petal to prevent wind from entering the pipe above the feed port 6.

[0022] Working principle: The device is fixed to the sowing structure of the seeder through a bracket, and a pipe is used to connect the feed port 6 and the box for storing fertilizer, and then a pipe is used to connect the discharge port and the fertilizer knife. After the connection is completed, the fan 1 is started, and the wind force generated by the fan 1 will be transported to the fertilizer distribution pipe 5, causing the fan blades 72 to rotate, driving the rotating roller 71 as a whole to rotate in the fertilizer distribution pipe 5, thereby stirring and beating the fertilizer. When the rotating roller 71 performs a circular motion, the lifting block 73 performs a reciprocating linear motion and moves up and down to puncture and lift the feed port 6, and transport the fertilizer inside the feed port 6 to the fertilizer distribution pipe 5. The fertilizer in the fertilizer distribution pipe 5 is blown by the wind and enters the discharge port, and is then transported to the fertilizer knife to complete the fertilization operation.
