[0027] An embodiment of the present utility model provides a saline-alkali land grass mixed seeding device.

[0028] Please refer to Figure 1 , including a granule storage 1 and a first one-way motor 2. Both the granule storage 1 and the first one-way motor 2 are prior arts and will not be elaborated in detail. The setting of the granule storage 1 can enable seeds to enter the next component in an orderly manner, facilitating seeding operations. The setting of the first one-way motor 2 can effectively provide sufficient power support for changing the spacing between seed sowings.

[0029] Please refer to Figure 2 , Figure 3 and Figure 6 , the output rotating shaft of the first one-way motor 2 is fixedly connected to one end of the one-way lead screw 3. The outer circumferential surface of the one-way lead screw 3 is threadedly connected to the middle part of the position control module 4. The position control module 4 is fixedly connected to one side of the position control guide plate 5. The position control guide plate 5 slides inside the component support frame 11. The close cooperation between the one-way lead screw 3 and the position control module 4 can make the position control guide plate 5 perform a vertical lifting movement under the restriction of the component support frame 11, thus ensuring the smoothness of the position control guide plate 5 during the movement.

[0030] Please refer to Figure 3 , a strip-shaped limit tooth plate 14 is fixedly arranged on one side of the component support frame 11. The strip-shaped limit tooth plate 14 is slidably connected to the limit support housing 15. The bottom of the limit support housing 15 is fixedly connected to the upper surface of the support balance base 16. The setting of the limit support housing 15 can effectively limit the strip-shaped limit tooth plate 14, thus ensuring that the strip-shaped limit tooth plate 14 will not tilt or fall off during the movement.

[0031] Please refer to Figure 2The lower surface of the supporting balance base 16 is fixedly provided with one-way wheels 23, and there are four groups of one-way wheels 23. The setting of multiple groups of one-way wheels 23 ensures the stability of the mixing device during movement and is not prone to swinging. The upper surface of the supporting balance base 16 is fixedly provided with an external handle 24. The setting of the external handle 24 makes it convenient for the staff to push the mixing device to move.

[0032] See also Figure 3 The supporting balance base 16 is connected to the linkage bearing 17 through a vertical plate, which ensures that the linkage bearing 17 can rotate in situ. A first sprocket 19 is fixedly arranged on the outer circumferential surface of the linkage bearing 17. The first sprocket 19 is transmission-connected to the second sprocket 21 through a conveying chain 20. The second sprocket 21 is fixedly connected to the output shaft of the second unidirectional motor 22. The bottom of the second unidirectional motor 22 is fixedly connected to the upper surface of the supporting balance base 16. The close fit between the first sprocket 19, the conveying chain 20, the second sprocket 21 and the second unidirectional motor 22 can effectively rotate the linkage bearing 17, and it is not easy to slip. The second unidirectional motor 22 is a prior art and will not be described in detail. The setting of the second unidirectional motor 22 provides effective power for changing the height of subsequent sowing components.

[0033] See also Figure 3 A flat gear 18 is fixedly arranged on the outer circumferential surface of the linkage bearing 17. The teeth on the outer circumferential surface of the flat gear 18 mesh with the teeth on one side of the bar-shaped limit tooth plate 14. The flat gear 18 and the bar-shaped limit tooth plate 14 cooperate with each other. When the flat gear 18 rotates, the bar-shaped limit tooth plate 14 performs vertical lifting operations under the restriction of the limiting support shell 15.

[0034] See also Figure 1 and Figure 4 A positioning guide rod 12 is fixedly arranged inside the component support frame 11. There are two groups of positioning guide rods 12. Both groups of positioning guide rods 12 are slidably connected to the positioning linkage module 8. The setting of multiple groups of positioning guide rods 12 can effectively support the positioning linkage module 8 and ensure the stability of the positioning linkage module 8 during movement. A soil covering push plate 13 is fixedly arranged at the bottom of the positioning linkage module 8. The setting of the soil covering push plate 13 can smooth the turned-over soil and cover the seeds.

[0035] See also Figure 4 , Figure 5 and Figure 6, the position control guide plate 5 is provided with a guide groove 6, and a limiting linkage column 7 is arranged inside the guide groove 6. The arrangement of the guide groove 6 can effectively limit the limiting linkage column 7, so that the limiting linkage column 7 drives the positioning linkage module 8 to move. The limiting linkage column 7 is fixedly connected to the positioning linkage module 8, and the positioning linkage module 8 is fixedly connected to the seed discharging pipe 9. The setting of the seed discharging pipe 9 ensures that the seeds fall smoothly at the designated position. The seed discharging pipe 9 is fixedly connected to the soil turning module 10. The setting of the soil turning module 10 can turn over the soil by external force movement, which is convenient for sowing. The particle separation storage device 1 is connected to the seed discharging pipe 9 through the conveying hose 25, and the conveying hose 25 has the characteristic of being stretchable.

[0036] Working principle: Start the first one-way motor 2 to work, so that the one-way lead screw 3 rotates, driving the position control module 4 to lift, thereby causing the subsequent position control guide plate 5 to lift, so that the limiting linkage column 7 slides in the guide groove 6 opened on the position control guide plate 5. Thus, under the limitation of the positioning guide rod 12, the positioning linkage module 8 slides on the positioning guide rod 12, thereby driving the seed discharging pipe 9 to move. At this time, multiple groups of seed discharging pipes 9 move simultaneously, and the soil turning module 10 and the soil covering push plate 13 move accordingly, so as to adjust the spacing between sowing, ensuring the growth of seeds. Start the second one-way motor 22 to work, driving the second sprocket 21 to rotate the first sprocket 19 through the conveying chain 20, so that the linkage bearing 17 drives the planar gear 18 to rotate, driving the strip-shaped limiting tooth plate 14 to slide in the limiting support housing 15, so that the component support frame 11 and subsequent multiple groups of components move synchronously, and the soil turning module 10 is inserted into the designated depth of the soil. Push the mixed sowing device to move by external force. At this time, under the action of the particle separation storage device 1, the seeds smoothly enter the seed discharging pipe 9 through the conveying hose 25, and then fall on the designated soil from the seed discharging pipe 9 to complete the sowing operation.
