[0030] It should be understood that when used in this specification and the appended claims, the terms "comprises" and "comprising" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0031] It should also be understood that the terms used in the description of the embodiments of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0032] Specific embodiments of the present invention are shown in the drawings. A traditional Chinese medicine drying device for livestock and poultry includes a drying box 1 and a heating plate 5; it also includes a driving assembly and a hot air drying assembly;

[0033] A number of electric heating tubes 25 are arranged on the lower end surface of the heating plate 5. The heating plate 5 is installed at the upper end inside the drying box 1. The driving assembly is used to drive the heating plate 5 to rotate.

[0034] The hot air drying assembly includes a heating blower 16, an air supply pipe 15, an air outlet plate 12 and a placement plate 13. The placement plate 13 is arranged inside the drying box 1. A number of ventilation holes 14 are formed on the placement plate 13. The air outlet plate 12 is installed on the lower end surface of the placement plate 13. One end of the air supply pipe 15 is connected to the heating blower 16, and the other end is connected to the air outlet plate 12.

[0035] In the above solution, the driving assembly drives the heating plate to rotate, so that the electric heating tubes on the heating plate can heat the Chinese medicinal materials in the drying box more evenly, improving the drying efficiency. Moreover, the heating blower heats the Chinese medicinal materials placed at the bottom of the placement plate, and the hot air generated by the heating blower accelerates the air convection in the drying chamber, further improving the drying efficiency.

[0036] As another embodiment of the present invention, as Figure 1 shown, the driving assembly includes a driving motor 2, a connecting shaft 3 and a connecting plate 4. The driving motor 2 is arranged at the upper end of the drying box 1. The connecting shaft 3 is connected to the output end of the driving motor 2 and extends into the drying box 1. The connecting plate 4 is installed at the end of the connecting shaft 3 far from the driving motor 2. The heating plate 5 is installed at the lower end of the connecting plate 4. When performing heating and drying, the driving motor is turned on to drive the heating plate to rotate, and the electric heating tubes on the heating plate evenly heat the Chinese medicinal materials in the drying chamber.

[0037] Furthermore, in order to improve the stability of the heating plate during rotation, a number of rollers 6 are arranged at the edge position of the lower end surface of the heating plate 5. An annular positioning plate 7 is arranged at the corresponding position on the side of the drying box 1 where the rollers 6 are located. The rollers 6 can roll on the upper end surface of the annular positioning plate 7. When the heating plate rotates, the rollers rotate on the upper end surface of the annular positioning plate, providing a part of the supporting force for the rotation of the heating plate, making the heating plate rotate more smoothly.

[0038] As another embodiment of the present invention, the drying device in this embodiment further includes a dust removal assembly, and the dust removal assembly is communicated with the inside of the drying box 1.

[0039] In this embodiment, the dust removal assembly mainly includes an induced draft fan 11, a dust suction plate 8, a dust suction chamber and a connecting pipe 10. The dust suction plate 8, the dust suction chamber and the induced draft fan 11 are connected in sequence through the connecting pipe 10. The dust suction plate 8 is arranged inside the drying box 1.

[0040] Specifically, the dust collection chamber includes a housing and a filtering mechanism. The housing includes an upper housing 9 and a lower housing 35. The filtering mechanism includes a plurality of filter cartridges 19. A plurality of rows of mounting holes 31 for mounting the filter cartridges 19 are provided on the upper housing 9. A plurality of receiving holes 20 are provided at positions corresponding to the mounting holes 31 on the lower housing 35. After the filter cartridge 19 exceeds a set weight, it disengages from the mounting hole 31 and falls into the receiving hole 20. Among them, the specific installation method of the filter cartridge is that a magnet 30 is provided at the bottom of the mounting hole 31, and an iron block 29 that is attracted to the magnet 30 is provided at the upper end of the filter cartridge 19.

[0041] Specifically, in the present invention, the filter cartridge adsorbs the dust in the air passing through the dust collection chamber. Since the dust adsorption ability of the filter cartridge decreases as the amount of adsorbed dust increases, when the filter cartridge absorbs a certain amount of dust, its dust adsorption ability basically reaches saturation, and when the dust reaches a certain level, it will block the filter cartridge, affecting the smoothness of air outlet and greatly reducing the dust removal effect.

[0042] In the above solution, the filter cartridge is fixed in the mounting hole by the adsorption of a magnet and an iron block. First, the filter cartridges in the front row absorb and intercept most of the dust. While the filter cartridges continuously adsorb and intercept the dust in the air, their mass continuously increases. When the weight increases to a certain extent (the dust absorption ability of the filter cartridge is close to saturation and the dust absorption effect is greatly weakened), the gravity of the filter cartridge plus the dust is greater than the adsorption force of the magnet and the iron block, and the filter cartridge falls into the receiving hole. The filter cartridges in the rear row can continue to ensure the absorption and interception of dust. Through the above solution, on the one hand, it can ensure the interception of the dust in the air passing through the dust collection chamber, and on the other hand, the filter cartridge with the dust absorption ability close to saturation can timely fall into the receiving hole, without affecting the smoothness of air outlet and ensuring the dust removal effect.

[0043] Among them, in the actual production process, the air entering the dust collection chamber is not evenly distributed. If a traditional whole row of filter meshes is used for filtration, it will lead to the situation that the left side of the filter mesh is blocked by dust first due to more air flow on the left side of the filter mesh, while the middle and right sides of the filter mesh still have dust absorption ability. However, a part of the blocked filter mesh will greatly affect the smoothness of air outlet and greatly reduce the dust removal effect. In this solution, a plurality of filter cartridges are used to form multiple rows for dust collection. When the dust absorption ability of a certain filter cartridge in the same row of filter cartridges reaches saturation first, it can timely fall into the receiving hole, and the remaining filter cartridges in the same row as this filter cartridge can still be used normally, without the need to replace the whole row, greatly improving the utilization rate of the filter cartridge. Moreover, in the present invention, the filter cartridge is fixed by a magnet and an iron block, which can automatically judge whether the dust absorption ability of the filter cartridge is close to saturation.

[0044] Specifically, in the present invention, the attractive force between the magnet and the iron block is equal to the weight of the filter box itself plus the weight of the dust absorbed when its dust absorption capacity is close to saturation. Its specific value can be obtained through experiments and calculations. Of course, if the filter box is relatively light and the attractive force between the magnet and the iron block is relatively large, a counterweight block 21 can be added to the bottom of the filter box. The specific weight of the counterweight block can be set according to the actual situation and will not be elaborated here.

[0045] It should be noted that since the filter box is fixed by the attraction between the magnet and the iron block, and the attractive force between the magnet and the iron block is not particularly large, when the filter box is placed in the installation hole and assembled, the filter box is likely to fall off due to the shaking of the upper shell, affecting the normal installation.

[0046] A number of limiting components are also provided on the upper shell 9. The limiting components include a connecting rod 18, a spring 23 and an adjusting head 32. An activity hole 17 for accommodating the connecting rod 18 is provided on the upper shell 9. A number of L-shaped limiting heads 27 are provided on the connecting rod 18. The activity hole 17 is communicated with the installation hole 31 through an activity groove 26. The L-shaped limiting heads 27 are movably matched with the activity groove 26. A clamping groove 28 matched with the L-shaped limiting heads 27 is provided on the filter box 19. A limiting plate one 22 is provided in the activity hole 17. A through hole matched with the connecting rod 18 is provided on the limiting plate one 22. A limiting plate two 24 is also provided on the connecting rod 18. The spring 23 is sleeved on the connecting rod 18 and abuts against the limiting plate one 22 and the limiting plate two 24 at both ends respectively. An adjusting hole 33 is provided on one side of the upper shell 9. The adjusting hole 33 is communicated with the activity hole 17. A section of thread is provided at the bottom of the adjusting hole 33. The adjusting head 32 is rotatably connected with the connecting rod 18. An external thread 34 matched with the thread is provided on the outer circumferential surface of the adjusting head 32.

[0047] In the above solution, when the upper shell and the lower shell need to be assembled after the filter box is installed in the installation hole, push the adjusting head in the direction of spring compression and rotate the adjusting head at the same time. The external thread on the adjusting head is matched with the thread in the adjusting hole, and the L-shaped limiting head is clamped into the clamping groove on the filter box to limit the filter box, preventing the filter box from falling off due to large vibrations during installation; after the upper shell and the lower shell are assembled, rotate the adjusting head in the reverse direction to disengage the external thread from the thread, and the connecting rod moves in the direction of spring elongation under the action of the spring, driving the L-shaped limiting head to disengage from the clamping groove.

[0048] In order to prevent the connecting rod from rotating when the adjusting head is rotated, a guiding groove is provided in the through hole, and a guiding convex rib 36 is provided at the position corresponding to the guiding groove on the connecting rod 18. The cooperation between the guiding groove and the guiding convex rib can prevent the connecting rod from rotating.

[0049] Among them, it should be noted that in order to prevent dust from passing through the lower end of the filter box and affecting the interception of dust, after the filter box 19 is installed, the lower end is flush with the upper end of the receiving hole 20 or a small section of the lower end of the filter box enters the receiving hole, which can effectively improve the dust interception effect; moreover, a baffle 37 is provided between every two adjacent mounting holes in each row. The upper end of the baffle is connected to the top of the upper housing, and the lower end is in contact with the upper end surface of the lower housing. After the filter box is installed, both sides of the filter box are in contact with the baffle to prevent dust from passing through the gap between two adjacent filter boxes, further improving the dust interception effect.

[0050] The above only describes the best embodiments of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
