[0002] The traditional method of sowing Chinese medicinal materials mainly relies on manual sowing. This method is not only labor-intensive, but also has poor sowing uniformity and inaccurate control of seed quantity, which affects the final yield and quality of Chinese medicinal materials. Utility Model Content

[0003] The utility model aims to provide a precision sowing tool for small-grain Chinese medicinal material seeds, so as to solve the problems of poor uniformity of manual sowing and inaccurate control of seeding amount when sowing small-grain Chinese medicinal material seeds in the prior art.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] The basic technical solution provided by the utility model is: a precision sowing tool for small-grain seeds of traditional Chinese medicine, comprising a box body, a support frame connected to the lower side of the box body, a wheel connected to the bottom end of the support frame, four groups of conical cavities are provided at the lower end of the box body, the four groups of conical cavities are provided with quantitative pipes, the four groups of quantitative pipes are rotatably connected to transmission rollers, the four groups of transmission rollers are coaxially connected through a rotating shaft, the rotating shaft is provided with a worm gear, the box body is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a worm meshing with the worm gear, the lower ends of the quantitative pipes are fixedly connected to a hose, the support frame is slidably connected to a discharge pipe, the lower end of the hose is passed through the discharge pipe, and the support frame is provided with an adjustment mechanism for adjusting the spacing between the four groups of discharge pipes.

[0006] The principle of the basic technical solution: the distance between the discharge pipes is adjusted by the adjustment mechanism. The box is used to hold Chinese medicinal seeds. The Chinese medicinal seeds pass through four groups of conical cavities and reach the top of each group of quantitative pipes respectively. By starting the motor, the motor drives the transmission roller to rotate through the cooperation of the worm gear, so that the Chinese medicinal seeds pass through the quantitative pipes and enter the hose. The Chinese medicinal seeds fall after passing through the hose to the discharge pipe.

[0007] The beneficial effects of the basic technical solution are: by periodically controlling the rotation of the motor, the transmission roller is controlled to perform corresponding periodic rotation, and by controlling the number of revolutions of the motor each time, the number of revolutions of the transmission roller each time is controlled, thereby achieving the purpose of controlling the amount of Chinese medicinal seeds discharged each time; the adjustment mechanism can flexibly adjust the spacing of the discharge pipe according to actual needs, and the hose and the discharge pipe are slidably connected. When the spacing of the discharge pipe changes, the hose will not be bent, thereby ensuring the smoothness of the seeds falling therein; thereby solving the problems of poor uniformity of manual sowing and inaccurate control of seeding amount when sowing small-grain Chinese medicinal seeds in the existing technology, and at the same time, it can be adaptively adjusted according to the row spacing of different Chinese medicinal seeds, with high reliability.

[0008] Preferably, the discharge pipe is provided with a slider, the support frame is provided with a slide rail, and the discharge pipe and the support frame are slidably connected via the slider and the slide rail.

[0009] Through the above arrangement, the slider is connected to the slide rail, which has good stability and high reliability.

[0010] Preferably, the slide rail is provided with scale lines.

[0011] Through the above arrangement, the user can observe the distance between each group of discharge pipes through the scale lines, thereby improving its accuracy.

[0012] Preferably, the adjustment mechanism includes a double-headed threaded rod 1 and a double-headed threaded rod 2, both of which are slidably connected to the support frame, the double-headed threaded rod 1 is threadedly connected to the two groups of sliders in the middle, and the double-headed threaded rod 2 is threadedly connected to the two groups of sliders on the outside.

[0013] Through the above arrangement, the double-headed threaded rod one drives the two middle groups of sliders to move, and the double-headed threaded rod two drives the two outer groups of sliders to move; since the threads at both ends of the double-headed threaded rod have opposite rotation directions, when the double-headed threaded rod one is rotated forward / reverse, the two middle groups of sliders drive the corresponding two groups of discharge pipes to move toward / backward; when the double-headed threaded rod two is rotated forward / reverse, the two outer groups of sliders drive the corresponding two groups of discharge pipes to move toward / backward, thereby changing the distance between the four groups of discharge pipes.

[0014] Preferably, both ends of the double-headed threaded rod one are fixedly connected to a driving wheel, and both ends of the double-headed threaded rod two are fixedly connected to a driven wheel, the driving wheel and the driven wheel are connected by a transmission belt, the radius of the driving wheel is three times the radius of the driven wheel, and the lead of the double-headed threaded rod one is the same as that of the double-headed threaded rod two.

[0015] Through the above setting, the radius of the driving wheel is three times the radius of the driven wheel, so the rotation speed of the driven wheel is three times that of the driving wheel. Since the lead of the double-headed threaded rod one and the double-headed threaded rod two are the same, the initial distance between the two adjacent groups of discharge pipes is set to be equal. When the double-headed threaded rod one is rotated, it drives the two middle groups of discharge pipes to move toward / backwards. At the same time, it drives the double-headed threaded rod two to rotate through the transmission belt. The double-headed threaded rod two rotates at a speed three times that of the double-headed threaded rod one, thereby driving the two outer groups of discharge pipes to move toward / backwards at a speed three times that of the middle two groups of discharge pipes. Therefore, the changing distance between the two adjacent groups of discharge pipes is always the same, thereby achieving the purpose of comprehensively adjusting the distance between the discharge pipes.

[0016] Preferably, the driving wheel is fixedly connected to a handwheel.

[0017] Through the above arrangement, the convenience of rotating the driving wheel is improved.

[0018] Preferably, the box is provided with a control module, and the control module is electrically connected to the motor to control the operation thereof.

[0019] The above settings are helpful to set the speed of the motor, thereby changing the discharge speed of the transmission roller. At the same time, the motor can be set to shut down at a fixed time, which is helpful to improve the effect of quantitative seeding.

[0020] Preferably, the support frame is fixedly connected to a mounting plate, and the mounting plate is provided with multiple groups of threaded holes.

[0021] Through the above arrangement, the device is fixed to the traction device through the mounting plate.

[0022] Preferably, the box body is connected to a cover plate via a hinge, and the cover plate is provided with a handle.

[0023] Through the above arrangement, the user can easily open and close the cover through the handle, so that the medicinal seeds can be added conveniently. BRIEF DESCRIPTION OF THE DRAWINGS
