Since agricultural operations usually cover several acres or dozens of acres, the overall efficiency is greatly reduced.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a seeding device for agricultural machinery operation, comprising a bearing platform, a guide cylinder and a hydraulic cylinder;

[0008] The guide cylinder is telescopically arranged on the bearing platform, the hydraulic cylinder is placed on the bearing platform, and the hydraulic cylinder is located between two guide cylinders close to each other, and a sorting module is arranged below the bearing platform;

[0009] The output end of the guide cylinder is hinged with a semi-conical cylinder, the hinge point between the guide cylinder and the semi-conical cylinder is set as a rotation axis, a driving member is installed on the inner edge of the bottom end of the guide cylinder, the output end of the driving member is connected to the inner edge of the semi-conical cylinder, and the flipping action of the semi-conical cylinder can be controlled by the driving member;

[0010] The output end of the hydraulic cylinder is butted with a connecting plate, and the end of the connecting plate is butted with the surface of the guide cylinder, wherein when the hydraulic cylinder is controlled and driven, the connecting plate links the multiple guide cylinders together to move toward the soil;

[0011] A material guide roller is hinged in the guide cylinder, and a material guide groove is provided on the surface of the material guide roller. Under the action of the material guide groove, seeds can be quantitatively loaded and output in a single time.

[0012] As an optimal technical solution for a seeding device for agricultural machinery operations, the sorting module includes V-plate 1 and V-plate 2, wherein V-plate 1 is located in the front position of the overall device, and V-plate 2 is located in the rear position of the overall device. Under the action of V-plate 1, sudden protrusions or debris on the ground can be pushed away, making it convenient to insert the semi-cone into the soil. Under the action of V-plate 2, the soil beside the hole where seeding is completed can be backfilled into the hole, thereby improving the overall seeding efficiency.

[0013] As an optimal technical solution for a seeding device for agricultural machinery operations, a material guide seat is installed on the inner edge of the guide cylinder, and the material guide seat is located above the material guide roller. Due to the characteristics of the material guide seat, seeds can be better guided into the material guide trough.

[0014] As an optimal technical solution for a seeding device for agricultural machinery operations, a connecting rod is hinged on the rotating shaft, a linkage plate is hinged on the other end of the connecting rod, and the linkage plate can telescopically move on the connecting rod. The linkage plate is telescopically arranged in the guide cylinder, and one side of the linkage plate is provided with tooth patterns. When the semi-conical cylinder flips, the linkage plate can telescopically move under the action of the rotating shaft and the connecting rod.

[0015] As an optimal technical solution for a seeding device for agricultural machinery operations, switch one and switch two are installed at the edge of the linkage plate, switch one is located in the middle of the linkage plate, and switch two is located at the top of the linkage plate.

[0019] Beneficial effects of the present invention:

[0020] 1. The seeding device for agricultural machinery operation is inserted into the soil through a hydraulic cylinder and a connecting plate, and a plurality of guide cylinders are linked to the driving member, the rotating shaft, the connecting rod and the linkage plate under the action of the opening of the semi-cone cylinder, so that when the semi-cone cylinder is opened, the transmission shaft can link the guide roller to move, and the guide roller rotates the specified number of seeds through the guide groove and drops them to the position of the semi-cone cylinder. When the semi-cone cylinder is completely turned over, the guide roller rotates 180 degrees, and the seeds can be sown into the dug hole, thereby realizing a single automatic quantitative sowing, thereby improving the overall sowing efficiency;

[0021] 2. The seeding device for agricultural machinery operation touches the second positioning plate through the second switch. At this time, the motor drives the threaded sleeve and the linkage plate to move through the screw. At this time, the linkage plate is no longer engaged with the transmission shaft. After the seeding is completed, the semi-conical cylinder retracts and the linkage plate moves downward. At this time, the guide roller does not move. When it is fully returned, the first switch touches the first positioning plate. At this time, the motor drives in the reverse direction and the linkage plate returns to the initial position, which can prevent the semi-conical cylinder from causing the seeds to continue to be exported when it retracts, and achieves the effect of overall stable and smooth operation;

[0022] 3. The sowing device for agricultural machinery operation can push away the sudden protrusions or debris on the ground through the action of V-plate 1, making it convenient for the semi-cone cylinder to be inserted into the soil. Under the action of V-plate 2, the soil beside the hole after sowing can be backfilled into the hole, thereby improving the overall sowing efficiency.
