Description

Technical Field

[0001] This utility model relates to the technical field of precision seed sowing devices, and in particular to a precision sowing device suitable for a variety of seeds. Background Technology

[0002] The common practice when sowing seeds is to first dig a trench, then manually place the seeds into the trench, and finally cover them with soil. However, this method has many drawbacks. For example, it requires multiple steps for sowing, resulting in low work efficiency. If the trench is too shallow, the seed survival rate will be low. Using tools such as shovels to dig trenches is strenuous and can cause fatigue after prolonged use.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] A precision seeding device suitable for various types of seeds includes;

[0005] The seeder frame and rotating rollers are arranged at the front and rear ends of the seeder frame, one of the rollers being driven by a first drive motor fixed to the seeder frame;

[0006] A pneumatic feeding device is mounted in the middle of the seeder frame. The pneumatic feeding device has at least one upward-opening hopper for holding seeds, and also includes a pneumatic seed-taking suction pipe and a drive component for driving the pneumatic seed-taking suction pipe to rotate, as well as an air pump connected to the pneumatic seed-taking suction pipe.

[0007] The discharging and sowing funnel concentrates the seeds poured out by the pneumatic seed-taking pipe and scatters them at a predetermined location on the ground;

[0008] An electrical control box is used to control the electrical devices on the first drive motor and the pneumatic material distribution device.

[0009] Preferably, the pneumatic feeding device includes a seed hopper fixed in the middle of the seeder frame, the seed hopper being used to store seeds; the pneumatic seed suction pipe includes an air pipe rotatably mounted on the seeder frame and a branch pipe fixed to the air pipe and communicating with the air pipe; it also includes a support frame fixed on the seeder frame and a discharge sowing funnel fixed at intervals on the support frame; the discharge sowing funnel corresponds to the branch pipe; the air pipe is driven to rotate by a motor, and the two stroke limits of the outer end of the branch pipe are insertion into the seed hopper and insertion into the discharge sowing funnel, respectively; when the branch pipe is inserted into the seed hopper, an air pump draws air to suck the seeds into the branch pipe, then the air pipe is rotated to extend the front end of the branch pipe into the discharge sowing funnel, and then the air pump stops drawing air, so that the seeds slide into the discharge sowing funnel under the action of weight.

[0010] Preferably, the diameter of the vent hole at the connection between the bronchus and the trachea is smaller than the diameter of the seed. This ensures that the seed will not enter the trachea while the seed is inhaling normally, and that the seed can slide out of the bronchus after the seed stops inhaling.

[0011] Preferably, a second drive motor is fixedly installed on the seeder frame, and the second drive motor is connected to the air pipe through a synchronous belt transmission component to drive it.

[0012] Preferably, the seeder frame is also fixedly equipped with two laser detectors. The laser detectors illuminate the bronchus when it is at the limit position of its rotation stroke. By obtaining whether the bronchus is at the limit position through a set distance threshold, the second drive motor is controlled to reverse through the electrical control box. Specifically, when the bronchus is in the seed hopper and is illuminated by one of the laser detectors, the illumination distance is at a predetermined threshold. Then, the second drive motor drives the bronchus to rotate and extend the bronchus into the discharge and sowing funnel. When the other laser detector illuminates the bronchus, the illumination distance is at a predetermined threshold. Then, under the control of the electrical control box, the bronchus is driven to reverse by the second drive motor.

[0013] Preferably, the discharging and sowing funnel is fixedly provided with a U-shaped overrun groove, and the front end of the bronchus can extend into the interior of the discharging and sowing funnel through the U-shaped overrun groove to ensure that the seeds are not easily dropped out.

[0014] The advantages and positive effects of this utility model are:

[0015] 1. It has a simple structure and is easy to sow. The air suction device can move seeds of various sizes, achieving more accurate sowing compared to existing technologies. Attached Figure Description

When the bronchus 17 is inserted into the seed hopper 15, the air pump draws air to suck the seeds into the bronchus 17, and then the air tube 16 is rotated to extend the front end of the bronchus 17 into the discharge and sowing funnel 19, and then the air pump stops drawing air. In this way, the seeds slide into the discharge and sowing funnel 19 under the action of weight.

[0030] Preferably, the seeder frame 11 is also fixedly equipped with two laser detectors 22. The laser detectors 22 illuminate the bronchus 17 when it is at the limit position of its rotation stroke. By obtaining whether the bronchus 17 is at the limit position through a set distance threshold, the second drive motor 21 is controlled to reverse through the electrical control box 14. Specifically, when the bronchus 17 is in the seed hopper 15 and is illuminated by one of the laser detectors 22, the illumination distance is at a predetermined threshold. Then, the second drive motor 21 drives the air pipe 16 to rotate and extend the bronchus 17 into the discharge and sowing funnel 19.
