Technical Field

[0001] The invention relates to the technical field of sowing equipment, and in particular to an integrated sowing device for soybean planting in saline-alkali land. Background Art

[0002] Soybeans are suitable for growing in neutral to slightly acidic soils. If the soil is too acidic, the soil pH value can be increased by applying lime; if the soil is too alkaline, acidic substances such as sulfur powder can be applied to adjust it; in order to improve some saline-alkali areas, planting is often used to improve the soil structure. Since soybean varieties have good salt-alkali tolerance, before planting, the salt in the soil can be leached by irrigation with fresh water. Increasing the application of organic fertilizers can improve the soil structure, increase the soil's water and fertilizer retention capacity, and reduce the salinity of the soil, and then carry out corresponding planting work; however, due to geographical reasons, some sections or planting areas are small, and large-scale sowing agricultural machinery cannot be used, resulting in high labor intensity.

[0037] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0038] First, when using, the bean seeds are put into the material barrel 31 in the feeding structure 3; the equipment is moved to the planting area by applying force through the handrail 16 and the wheels 13 on the wheel frame 11 at both ends of the beam 12;

[0039] The power is supplied by the battery 15 on the carrier plate 14 in the main structure 1, and the motor 36 of the device is driven by the controller 6. The shaft 35 is driven to rotate between the material box 32 and the box plate 34 through the pulley 37 and the belt 38, thereby driving the single bean discharge assembly 39 to rotate and transfer and discharge the single bean seeds in the barrel;

[0040] That is, the shaft 35 drives the material wheel 391 to rotate, and after receiving the beans through the material hole 51 on the material wheel 391, as the material wheel 391 rotates in the material box 32, when the material hole 51 is separated from the material box 32 and faces the material box 33, the bean seeds are separated from the material wheel 391, and the bean seeds pass through the discharge port 45 of the material box 33 and enter the sowing box 21 supported by the fixed frame 17;

[0041] The material wheel 391 is rotated to discharge the material. According to the demand, the adjusting screw 392 and the adjusting bolt are rotated. The adjusting screw 392 moves in the adjusting groove 52 to move the material bowl 394 and fix the material bowl 394. The material bowl 394 is located at different depths of the material hole 51 to adjust the diameter and quantity of different beans, so as to prevent the material wheel 391 from receiving too many beans during rotation.

[0042] When the bean seeds enter the sowing box 21, they will fall into the feeding tube 24 and fall below the feeding port 41. The spring 263 between the spring rods 262 will force the feeding claw 261 to close and stop the beans.

[0043] Then the equipment is moved to the corresponding position, and the hydraulic cylinder 23 on the support plate 22 in the sowing structure 2 can be driven to extend through the controller 6, so that the feeding pipe 24 is lowered from the sowing box 21, and the feeding assembly 26 is lowered and inserted into the soil, that is, the feeding claw 261 is inserted into the soil, and then as the feeding claw 261 descends, since the force rod 264 in the feeding assembly 26 is connected to the limiting groove 44 of the feeding arm 25, after the feeding claw 261 descends to a certain height, the other end of the force rod 264 moves to the bottom of the limiting groove 44 and is subjected to force, driving the movable feeding claw 261 to flip open, so that the beans can be dropped into the soil to complete the planting, and while pushing the equipment forward, the beans are completely separated from the feeding grip, and the hydraulic cylinder 23 is driven to shrink, and the feeding gripper is automatically closed by the force of the spring 263;

[0044] The extension and retraction length of the hydraulic cylinder 23 is set according to the sowing depth, and the height of the feeding arm 25 installed by bolts is adjusted at the same time, that is, the position of the force rod 264 in the limit groove 44 is adjusted, and the height of the feeding claw 261 is adjusted to make the force rod 264 contact with the bottom of the limit groove 44 and drive the feeding claw 261 to flip, thereby realizing the overall adjustment of the planting depth.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
