Description

Technical Field

[0001] The utility model relates to the technical field of sowing devices, in particular to a sowing device with an anti-blocking function. Background Art

[0002] A seeder is a planting machine that sows crop seeds. Among them, the no-till seeder can replace the original manual sowing, fertilization, and tillage steps with machinery and complete them in one step. It is widely used in economic crops such as corn, soybeans, potatoes, and garlic that are suitable for large-scale cultivation.

[0003] The Chinese patent disclosed in the patent number CN 220342832 U is a sowing device with an anti-blocking function, including a seed storage box, wherein a seed storage cavity, a disc groove, a funnel groove and a plurality of L-shaped grooves are respectively opened inside the seed storage box from top to bottom, a plurality of dredging pipes are fixedly installed on one side of the seed storage box, and the corresponding ends of the plurality of dredging pipes respectively penetrate the one side of the seed storage box and extend into the corresponding L-shaped grooves, and dredging rods are slidably installed inside the plurality of dredging pipes, and a first column is fixedly installed on one end of the plurality of dredging rods. By setting the dredging pipe, the dredging rod, the first column, the electric push rod and the first plate, when the device is used, when the discharge speed in the discharge pipe slows down or even stops discharging, the electric push rod can be controlled to work so that the first column pushes the dredging rod to move toward the L-shaped groove, thereby dredging the corn seeds blocked in the L-shaped groove, thereby ensuring the smooth progress of the sowing operation and improving the sowing efficiency.

[0004] During use, the above-mentioned device is used to unclog the seeds after they are blocked. During the unclogging process, the sowing device needs to stop working, resulting in reduced sowing efficiency. At the same time, during the sowing process, the seed discharge speed of the above-mentioned device does not match the movement speed of the sowing device. When the seed discharge speed remains unchanged, if the sowing device moves too fast or too slow, the sowing spacing will change, thereby affecting the growth and development of the seeds. Utility Model Content

[0005] The utility model aims to provide a sowing device with an anti-blocking function, which has the characteristics of preventing seeds from being blocked during the sowing process and ensuring that the spacing between seeds is the same after sowing.

[0010] In order to move the seeds in the seed storage tank to the seed placement groove, as a preferred sowing device with an anti-blocking function of the utility model, the lower end of the inner part of the seed storage tank is arranged as a funnel structure.

[0011] In order to prevent seeds from remaining on the upper end surface of the moving bar, as a preferred sowing device with anti-blocking function of the utility model, the upper end surface of the moving bar is configured as a spherical structure.

[0012] In order to increase the friction between the roller and the ground, as a preferred sowing device with an anti-blocking function of the utility model, the outer wall of the roller is provided with anti-slip textures.

[0014] The roller rotates by friction with the ground, and the roller cooperates with the pull rod to drive the connecting rod to move up and down, and the connecting rod cooperates with the moving bar to drive the seed placing slot to move up and down. When the seed placing slot is located in the seed storage slot, the seeds enter the seed placing slot, and then the seed placing slot moves downward through the moving bar, so that the seed placing slot is flush with the discharge pipe. At the same time, the air outlet of the fan is connected with the air hole, and then the fan blows the air flow into the seed placing slot through the air hole, and blows the seeds in the seed placing slot into the discharge pipe. At the same time, the blowing of the seeds by the air flow can make the seeds quickly discharged from the discharge pipe, prevent the seeds from staying in the discharge pipe, and avoid the seeds from being blocked in the discharge pipe, thereby preventing the seeds from being blocked during the sowing process. When the roller rotates one circle, the moving bar completes an up and down movement, and then the sowing frequency is controlled by the number of rotations of the roller, so that the spacing between the seeds after sowing is the same.
