[0027] The Cistanche seeding device provided by the application, like Figure 1As shown, including traction frame 1, seed bin 2, furrower 3 and seeding tube 4. The whole seeding device can be connected to the rear of the tractor through the traction frame 1, and the movement of the seeding device is realized by the tractor.

[0028] The seed bin 2 is fixedly connected above the traction frame 1 for placing the cistanche seed. The furrower 3 and the seeding tube 4 are adjustably connected below the traction frame, and the seeding tube 4 is fixedly connected behind the furrower 3; during seeding, the furrower 3 is placed in the soil, and as the tractor advances, the furrower 3 can automatically break the soil and open the furrow, and by adjusting the height of the furrower, the furrow depth can be adjusted, and in turn the seeding depth can be adjusted.

[0029] The bottom of the seed bin 2 is provided with a discharging pipe 5, and the discharging pipe 5 is provided with a control valve 6, which can adjust the amount of seed discharged; the control valve can be a rotary valve, a flashboard valve, etc. A telescopic seed conveying pipe 7 is arranged between the discharging pipe 5 and the seeding tube 4, which connects the discharging pipe 5 and the seeding tube 4, and the seeds in the seed bin are sequentially seeded in the seeding furrow opened by the furrower through the discharging pipe, the telescopic seed conveying pipe and the seeding tube, realizing automatic seeding of cistanche. The telescopic seed conveying pipe 7 has a certain telescopic amount, which can adapt to different seeding depths.

[0030] The seed bin 2, the furrower 3 and the seeding tube 4 can be multiple groups to realize simultaneous seeding of multiple rows. Preferably, the seed bin, the furrower and the seeding tube are two groups, respectively located on both sides of the traction frame 1.

[0031] The height-adjustable device of the furrower 3 and the seeding tube 4 can adopt a lead screw nut type, and the application provides a preferred embodiment as follows:

[0032] A support plate is arranged on the traction frame 1, and a plurality of thread holes 8 arranged in up-down direction are arranged on the support plate. A threaded column is arranged on the top of the furrower 3, and the height of the furrower is adjusted by passing through different thread holes 8. Compared with the lead screw nut, the thread holes arranged in up-down direction are more fixed in connection, and the problem of nut displacement and in turn the change of seeding depth caused by seeding vibration will not occur.

[0033] At present, the height of the rear traction rod of many tractors can be adjusted, and when the seeding device of the application is connected with the height-adjustable traction rod, the height of the whole seeding device can be further adjusted by adjusting the height of the traction rod, and in turn the height of the furrower and the seeding depth can be adjusted.

[0035] Preferably, the top of the seed chamber 2 is provided with an openable and closable cover. Opening the cover allows the addition of Cistanche deserticola seeds into the seed chamber, while closing the cover prevents debris from falling into the seed chamber and clogging the control valve and the sowing tube.

[0036] Preferably, support columns 10 are provided between the four top corners of the bottom of the seed bin 2 and the traction frame to support the seed bin.

[0037] Preferably, the left side of the traction frame has three suspension arms 11 for connecting to the traction device, one of which is located at the center of the upper part of the left traction frame, and the other two suspension arms are symmetrically located at the front and rear sides of the lower part of the left traction frame; a reinforcing diagonal bar 12 is provided between the top of the upper suspension arm and the right traction frame. The three traction points and the reinforcing diagonal bar can strengthen the connection between the traction frame and the tractor.

[0038] The overall shape of the traction frame can be adjusted according to the number of sowing components. When the traction frame, seed bin, furrowing plow, and sowing tube are a single unit, such as... Figure 2 As shown, the traction frame is preferably an isosceles triangle; the left side of the traction frame is the base of the isosceles triangle; the traction frame, seed bin, furrowing plow, and sowing pipe are located in the middle of the traction frame.

[0039] When there are two sets of traction frame, seed bin, furrowing plow and sowing tube; the traction frame is preferably rectangular; the left side of the traction frame is the left side of the rectangle; the two sets of traction frame, seed bin, furrowing plow and sowing tube are symmetrically located at the front and rear ends of the right side of the traction frame.

[0040] As those skilled in the art will understand, the sowing device provided in this application can be used not only for sowing Cistanche deserticola, but also for sowing other crops with similar needs.
