In a case of this embodiment, a second support plate 36 is vertically arranged at the rear right end of the work frame 1, and the upper end of the second support plate 36 is rotatably connected to the middle part of the rotating shaft 37, and the front side of the rotating shaft 37 is provided with multiple A hitting rod 38 uniformly distributed with respect to the center of the rotating shaft 37, and a third drive motor 39 is arranged on the middle rear side of the second support plate 36, the output shaft of the third drive motor 39 is fixedly connected to the third bevel gear 40, and the third drive motor 39 is fixedly connected to the third bevel gear 40. The bevel gear 40 meshes with the fourth bevel gear 41, and the fourth bevel gear 41 is fixedly connected to the rear end of the rotating shaft 37, so that the third driving motor 39 drives the rotating shaft 37 to rotate counterclockwise, so that the striking rod 38 revolves around the rotating shaft 37. The axis rotates counterclockwise.

In one case of this embodiment, the unloading assembly 18 includes a fixed bar 14 obliquely arranged at the end of the work frame 1, and the end of the fixed bar 14 close to the lifting mechanism 2 is provided with a bracket that can pass through two adjacent brackets. The unloading bar 17 of plate 13 gaps. The fixed bar 14 is arranged on the right side of the work frame 1, and the right end of the fixed bar 14 is inclined downwards. A front and back discharge bar 17 is provided at the left end of the fixed bar 14. When the supporting plate 13 moves down on the right side , the gap between the two rightmost pallets 13 will pass through the discharge rod 17, so that the medicinal plant placed on the pallet 13 falls on the discharge rod 17. At this time, the weight of the medicinal plant will be heavier due to the right end, so the medicinal plant The plant will fall to the right, and the discharge assembly 18 also includes a fixed rod 15 arranged on the end of the fixed bar 14 away from the discharge rod 17. The fixed rod 15 is evenly distributed with a plurality of guides vertically arranged with the fixed rod 15. Rod 16. The material guide rod 16 is all inclined to the lower right, and there is enough gap between the left end of the material guide rod 16 and the discharge rod 17 to facilitate the falling of the supporting plate 13, and the Chinese medicine plants will fall with the guide rod 16 after falling on the material guide rod 16. The material rod 16 slides down to the right, thereby realizing the effect of unloading.

In the implementation process of this embodiment, at first by setting support legs under the work frame 1, the whole work frame 1 is placed horizontally and stably, and the first drive motor 10, the second drive motor 31 and the third drive motor 39 are started. When the whole device can work normally, the first driving motor 10 drives the supporting plate 13 to rotate clockwise through the belt transmission mode, and at the same time, the second driving motor 31 makes the sliding seat 24 reciprocate left and right, and the third driving motor 39 will drive the hitting The rod 38 is rotated at high speed.

The operator puts the medicinal plants that need to be threshed on the tray 5 during the gap where the supporting plate 13 moves to the right, and keeps the part of the medicinal plants with seeds on the right side of the tray 5, when the supporting plate 13 is on the left side. When moving from bottom to top, supporting plate 13 will pass through the top of tray 5 from the bottom of pallet 5 by giving way to slot 6, and supporting plate 13 will hold up the medicinal material plants placed on pallet 5, when supporting plate 13 moves to After going up, it will be in contact with the upper pressing plate 27, and the second spring 35 will be adaptively compressed. At this time, the pressing plate 27 and the supporting plate 13 will realize the effect of clamping the left side of the medicinal plant, and the medicinal plant will follow the supporting plate. 13 moves to the right, and after moving to the right, it will contact the lower left side of the hitting rod 38 rotating counterclockwise, so that the part with grains at the right end of the medicinal plant is in contact with the hitting rod 38, and the grains are shot down by the hitting rod 38 Pass through the material guide rod 16 and fall below the working frame 1. As the pallet 13 continues to move to the right, the pallet 13 will be disengaged from the pressure plate 27. At this time, the unloading rod 17 will pass through the two adjacent pallets. gap between the plates 13, at this time, the unloading rod 17 will lift the medicinal plants, and the jacked-up position is just in the left position of the medicinal plants. At this time, the medicinal plants will rotate clockwise around the unloading rod 17, and the medicinal plants will The right end of the plant will fall on the material guide rod 16, and the medicinal material plant will slide to the right along with the material guide rod 16, and the medicinal material plant that finally completes the threshing will slide to the right side of the working frame 1, and as the threshing machine continues to work , the operator only needs to place the medicinal plants on the pallet 5 during the gap where the pallet 13 moves to the right.

The present invention is applicable to a traditional Chinese medicine thresher, through the cooperation of the rotating supporting plate 13 and the pressing plate 27, the supporting plate 13 and the pressing plate 27 will clamp the medicinal plants on the left tray 5 and then contact the hitting assembly 3 on the right The threshing process is achieved by contact, so that the operator will stay away from the high-speed rotating beating assembly 3 when using the device, and the safety of the entire thresher is better. At the same time, the unloading assembly 18 can complete unloading in time. The material guide rod 16 can achieve a certain screening effect, so that the working efficiency of the whole device is better.

It will be apparent to those skilled in the art that the invention is not limited to the details of the above-described exemplary embodiments, but that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Accordingly, the embodiments should be regarded in all points of view as exemplary and not restrictive, the scope of the invention being defined by the appended claims rather than the foregoing description, and it is therefore intended that the scope of the invention be defined by the appended claims rather than by the foregoing description.
