The bottom end of the outer wall of the fixed box 6 is fixedly connected with a lower circulation pipe 11, and the left outer wall of the fixed box 6 is fixedly connected with an upper circulation pipe 10. The end of the lower circulation pipe 11 away from the fixed box 6 is fixedly connected to the bottom end of the outer wall of the shell 3. The shell 3 is provided with filter holes corresponding to the lower circulation pipe 11, so that the hot air entering the shell 3 will enter the lower circulation pipe 11 and be sucked into the fixed box 6. The end of the upper circulation pipe 10 away from the fixed box 6 is fixedly connected to the outer wall of the hot air blower 8. By setting the upper circulation pipe 10, the hot air entering the fixed box 6 can be re-entered into the hot air blower 8, thereby avoiding the ineffective loss of heat energy.

[0030] Reference Figure 2-Figure 3 The outer wall of the bottom end of the shell 3 is elastically connected with a baffle plate 12 through a limit spring 13, one end of the limit spring 13 is fixedly connected to the inner side wall of the baffle plate 12, and the other end of the limit spring 13 is fixedly connected to the outer wall of the bottom end of the shell 3. The setting of the limit spring 13 fixes the fixed position of the baffle plate 12, and also applies an elastic effect to the baffle plate 12, so as to adjust the discharge amount of the medicinal materials after being dried. The baffle plate 12 is slidably connected to the inner wall of the bottom end of the shell 3, and the inner wall of the fixed box 6 is provided with a moisture absorption component 9, and the moisture absorption component 9 includes a moving frame 93, and the moving frame 93 is elastically connected to the inner wall of the fixed box 6 through a return spring 92, and one end of the return spring 92 is fixedly connected to the bottom end of the outer wall of the moving frame 93. The other end is fixedly connected to the bottom end of the inner wall of the fixed box 6. The function of the reset spring 92 is to automatically reset the position of the moving frame 93 after it is lowered. The top of the outer wall of the moving frame 93 is fixedly connected with an identification rod 91. The surface of the identification rod 91 is provided with a scale block. The descent of the scale block reminds the staff to replace the moisture absorption plate 94. The moving frame 93 is slidably connected to the inner wall of the fixed box 6. The identification rod 91 passes through and is slidably connected to the inner wall of the top of the fixed box 6. The inner wall of the moving frame 93 is detachably installed with two groups of moisture absorption plates 94. The moisture absorption plate 94 is a prior art. It absorbs the moisture generated by the medicinal materials after drying to avoid the internal cavity state, which causes the moisture to be absorbed on the inner wall. The inner wall of the shell 3 is provided with a breaking component 5.

[0031] Refer to the figure Figure 3 The breaking up component 5 includes a motor 51, which is fixedly connected to the top of the outer wall of the shell 3, and a rotating shaft 52 is rotatably connected to the bottom end of the inner wall of the shell 3. The output shaft of the motor 51 is fixedly connected to the rotating shaft 52, and a concave rod 53 is fixedly connected to the bottom end of the left side of the rotating shaft 52. The surface of the concave rod 53 is provided with multiple groups of notches, so that the medicinal materials can be broken up during the rotation process to avoid being adsorbed on the bottom end of the shell 3. The bottom end of the outer wall of the concave rod 53 contacts the bottom end of the inner wall of the shell 3, and the top end of the right side of the rotating shaft 52 is fixedly connected to a breaking up rod 54. The breaking up rod 54 is provided with multiple groups of cylindrical rods, which are used to grab and mess around inside the shell 3 to break up the medicinal materials.

[0032] Working principle: When drying the medicinal materials, first let the medicinal materials enter the interior of the shell 3 from the feed port 4. At this time, the hot air blower 8 can be started to make it work, and the fan inside it can be rotated to input hot air into the interior of the shell 3, and the motor 51 can be started to let its output shaft drive the concave rod 53 and the breaking rod 54 to rotate. The concave rod 53 can effectively prevent the medicinal materials from being too wet and adsorbed on the bottom end of the shell 3, and scrape and break them up, and use the breaking rod 54 to break up the clumped medicinal materials so that they can be evenly dried.

[0033] At the same time, during the drying process, hot air will be blown by the hot air blower 8 to dry the medicinal materials inside the shell 3. After the medicinal materials are dried, the moisture will enter the interior of the lower circulation pipe 11 along the through hole inside the shell 3 along with the hot air, and then enter the interior of the fixed box 6, so as to be adsorbed by the moisture absorption plate 94. The hot air that goes out together will re-enter the interior of the hot air blower 8 along the upper circulation pipe 10 and be recycled again, thereby improving the drying efficiency. At the same time, when the moisture absorption plate 94 absorbs enough moisture and needs to be replaced, it will drive the moving frame 93 to move downward on the inner wall of the fixed box 6 through its own adsorption weight, thereby driving the marking rod 91 to drop synchronously, thereby reminding the staff to replace the moisture absorption plate 94 in time. When the moisture absorption plate 94 is taken out, the moving frame 93 will be elastically acted upon by the reset spring 92 to restore it to its initial position. After the drying of the medicinal materials is completed, the stop plate 12 can be pulled to allow the limit spring 13 to be elastically compressed. At this time, the bottom end of the shell 3 is opened, thereby facilitating the quantitative unloading of the dried medicinal materials.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
