Specifically, when the rotary tube 22 rotates anticlockwise, the two rotary rods 34 are driven to synchronously rotate anticlockwise through the belt 33 respectively, the rotary rods 34 drive the half bevel gears 36 to rotate anticlockwise, when the right half bevel gear 36 rotates to be meshed with the corresponding bevel pinion 35, the left half bevel gear 36 is separated from the corresponding bevel pinion 35, the right half bevel gear 36 drives the corresponding bevel pinion 35 and the rotary shaft 20 to rotate backwards, and the right rotary shaft 20 drives the scraping rod 21 to swing forwards for a certain angle; when the left half bevel gear 36 rotates to be meshed with the corresponding bevel pinion 35, the right half bevel gear 36 is separated from the corresponding bevel pinion 35, the left half bevel gear 36 drives the corresponding bevel pinion 35 and the rotating shaft 20 to rotate forwards, and then the left rotating shaft 20 drives the scraping rod 21 to swing backwards by a certain angle; therefore, when the medicine pounding rod 13 moves upwards to drive the hammer 14 to lift upwards, the scraping rod 21 is driven to swing forwards or backwards, so that materials adhered to the inner wall of the accommodating groove 19 are scraped through the scraping rod 21, and the degree of automation is higher.
In order to improve the scraping effect of the scraping rod 21 on the material on the inner wall of the accommodating groove 19, in this embodiment, the half bevel gear 36 drives the corresponding bevel pinion 35 to rotate one hundred eighty degrees when rotating one circle, that is, when the side of the half bevel gear 36 provided with teeth is completely scratched by the bevel pinion 35, the bevel pinion 35 is driven to rotate one hundred eighty degrees, and the bevel pinion 35 drives the scraping rod 21 to swing one hundred eighty degrees through the rotating shaft 20.
In the initial state, as shown in fig. 4 to 6, the scraping rod 21 is positioned at the rear side of the two rotating shafts 20 in a horizontal state, the scraping rod 21 is positioned above the medicine tank 2, and at the moment, the two half bevel gears 36 are separated from the corresponding bevel pinions 35; when the medicine pounding rod 13 drives the hammer 14 to downwards finish a beating action, the top cylinder 18 drives the medicine pounding rod 13 to upwards move and drives the hammer 14 to upwards lift, the sliding column 24 acts on the inclined sliding groove 27 and drives the rotary pipe 22 to anticlockwise rotate by a certain angle when the medicine pounding rod 13 upwards moves, the rotary pipe 22 drives the two rotary rods 34 to anticlockwise rotate by one hundred eighty degrees through the belt 33, the rotary rod 34 drives the half bevel gear 36 to anticlockwise rotate by one hundred eighty degrees, teeth on the right half bevel gear 36 firstly completely scratch the right bevel gear 35 and drive the bevel gear 35 to backwards rotate by one hundred eighty degrees, the right bevel gear 35 drives the scraping rod 21 to downwards and forwards swing by one hundred eighty degrees through the rotary shaft 20, and the scraping range of the scraping rod 21 is enough to completely cover the inner wall of the accommodating groove 19; when the hammer 14 finishes the next striking action and lifts up again, the medicine pounding rod 13 drives the rotary tube 22 to rotate anticlockwise by a certain angle again, in the process, teeth on the left half bevel gear 36 completely scratch the left bevel gear 35 and drive the bevel gear 35 to rotate forwards by one hundred eighty degrees, and the bevel gear 35 on the left drives the scraping rod 21 to swing backwards downwards by one hundred eighty degrees through the rotary shaft 20, so that the scraping rod 21 can completely scrape the inner wall of the accommodating groove 19 each time the medicine pounding rod 13 and the hammer 14 lift up.
As shown in fig. 6, in order to limit the rotation angle of the scraper bar 21, limiting plates 37 matched with the scraper bar 21 are fixedly installed on the front and rear sides of the inner peripheral wall of the closed cover 12, and the two limiting plates 37 are symmetrically arranged relative to the axis of the rotating shaft 20, so that when the scraper bar 21 rotates to be attached to the bottom of any limiting plate 37, the scraper bar 21 rotates to be in a horizontal state.
As shown in fig. 6 and 7, in order to avoid that the scraping rod 21 rotates randomly when both the half bevel gears 36 are separated from the corresponding bevel pinions 35, a first connecting shaft 38 is screwed on the inner peripheral wall of the closed cover 12 right above the rotating shaft 20, a swinging plate is arranged on one side of the inner end of the rotating shaft 20, a second connecting shaft 39 eccentrically arranged with the rotating shaft 20 is screwed on the swinging plate, the second connecting shaft 39 and the scraping rod 21 are both positioned on the same side of the rotating shaft 20, the first connecting shaft 38 and the second connecting shaft 39 are both parallel to the rotating shaft 20, a tension spring 40 for pulling the scraping rod 21 to be attached to the bottom of the limiting plate 37 is connected between the first connecting shaft 38 and the second connecting shaft 39, two ends of the tension spring 40 are respectively hung on the first connecting shaft 38 and the second connecting shaft 39, and annular grooves for preventing the tension spring 40 from falling off are respectively arranged on the first connecting shaft 38 and the second connecting shaft 39.
The foregoing has shown and described the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
