DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a combined screen structure comprises:

[0030] The outer shell 20 is in the shape of a box with a hollow cavity. A feed pipe 21 is fixedly connected to the rear wall of the outer shell 20. The feed pipe 21 is in the shape of a rectangular tube and is connected to the cavity of the outer shell 20.

[0031] A discharge trough 22 extends through the front wall of the outer shell 20. A discharge plate 23 is rotatably connected to the wall of the outer shell 20 in the discharge trough 22. The discharge plate 23 can block the discharge trough 22. A sieve drum 25 is also rotatably connected to the cavity of the outer shell 20. The sieve drum 25 is cylindrical and is horizontally placed in the cavity of the outer shell 20. A plurality of sieve holes 26 are evenly arranged on the wall of the sieve drum 25. The sieve holes 26 are circular grooves. A connecting rod 27 is fixedly connected to the rear wall of the sieve drum 25. The connecting rod 27 is rotatably connected to the cavity of the outer shell 20. A motor for driving the connecting rod 27 to rotate in the cavity of the outer shell 20 is installed on the wall of the outer shell 20. The motor and the power supply are electrically connected. This is an existing technology and will not be described in detail here.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the anti-blocking structure can prevent the sieve hole 26 from being blocked by soil. The anti-blocking structure includes: a push rod 33, a hitting rod 34 and a trigger block 36. The push rod 33 is movably connected in the cavity of the shell 20, the hitting rod 34 is fixedly connected to the wall surface of the push rod 33, and the trigger block 36 is fixedly connected to the curved surface of the sieve cylinder 25. The hitting rod 34 can contact the outer wall surface of the sieve cylinder 25.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the push rod 33 is symmetrically arranged on the front and rear walls of the cavity of the shell 20, the hitting rod 34 is cylindrical, and the front and rear ends of the hitting rod 34 are fixedly connected to the symmetrical push rod 33 respectively. A plurality of trigger blocks 36 are evenly arranged on the arc surfaces of the front and rear walls of the screen drum 25, and the upper wall surface of the trigger block 36 is arc-shaped. The bottom of the push rod 33 can contact the arc surface of the trigger block 36. The anti-blocking structure also includes a bullet box 30, a bullet groove 31, a spring plate 32 and a top box 35. The bullet box 30 is symmetrically fixedly connected to the front and rear walls of the top of the cavity of the shell 20. The bullet groove 31 is opened in the cavity of each bullet box 30. The spring plate 32 is elastically connected in the bullet groove 31 by a spring. The top box 35 is fixedly connected between the symmetrical bullet boxes 30. The spring plate 32 is symmetrically fixedly connected on both sides of each push rod 33. The bullet groove 31 can adapt to the sliding of the push rod 33 and the symmetrical spring plate 32. The push rod 33 can slide vertically in the bullet groove 31, and the push rod 33 can pass through the bottom of the bullet box 30.

[0034] When in use, the pagoda leaves to be screened are poured in from the feed pipe 21, and the power is turned on. After entering the feed pipe 21, the pagoda leaves will enter the cavity of the sieve cylinder 25 in the cavity of the shell 20 along with the cavity of the feed pipe 21. The rotating sieve cylinder 25 will drive the pagoda leaves to turn in its cavity so that the soil is separated from the wall surface of the pagoda leaves. The separated soil will pass through the sieve hole 26. When the sieve cylinder 25 rotates, it will drive the trigger block 36 to rotate at the same time, and the bottom of the top rod 33 at the corresponding position will contact along the top wall surface of the trigger block 36, and the trigger block 36 will push the top rod 3 When the top rod 33 reaches the highest point of the spring slot 31, the spring plate 32 will be driven by the push rod 33 to move in the spring slot 31. When the push rod 33 drives the spring plate 32 to move upward, the spring at the top of the spring plate 32 will be compressed. After the bottom of the push rod 33 stops and contacts the wall of the trigger block 36, the spring will push the trigger block 36 downward. The push rod 33 will drive the hitting rod 34 to move downward. The hitting rod 34 can quickly contact the top of the screen drum 25 to vibrate out the soil stuck in the screen hole 26 to prevent blockage. After the discharge plate 23 is turned upward, the pagoda vegetable will be separated from the device at the discharge slot 22.

[0035] In summary, by setting up an anti-blocking structure, the screen drum 25 can be prevented from being blocked by the screened soil. This is because the anti-blocking structure drives the hitting rod 34 to intermittently beat the outer wall of the screen drum 25 as the screen drum 25 rotates, thereby vibrating the soil out of the screen hole 26. This allows the present solution to maintain the best screening effect during long-term operation. Therefore, compared with the prior art, the present solution has a higher screening efficiency during long-term use.

[0036] like Figure 2 and Figure 3 As shown, the anti-blocking structure also includes an unearthed groove 24, a flip rod 37 and a guide block 38. The unearthed groove 24 is opened through the bottom of the cavity of the shell 20, the flip rod 37 is fixedly connected to the cavity of the screen drum 25, and the guide block 38 is fixedly connected to the cavity of the shell 20. The unearthed groove 24 is located at the center of the cavity of the shell 20. The unearthed groove 24 is a rectangular groove, and the guide block 38 is a right-angled triangle block. The inclined surface position of the guide block 38 is an arc groove concave inward. The guide blocks 38 are symmetrically arranged on both sides of the bottom of the cavity of the shell 20. The size of the unearthed groove 24 is consistent with the spacing between the symmetrical guide blocks 38. The flip rod 37 is a semicircular rod. The flip rod 37 is respectively arranged between each group of adjacent sieve holes 26 on the inner wall of the cavity of the screen drum 25, and the length of each flip rod 37 is consistent with the length of the cavity of the screen drum 25.

[0037] When in use, after the pagoda leaves enter the cavity of the sieve drum 25, the rotating sieve drum 25 can drive the flipping rod 37 to flip the pagoda leaves in the cavity of the sieve drum 25. After the sieve hole 26 screens out the soil, it will move toward the unearthed groove 24 along the arc surface of the guide block 38, and then pass through the unearthed groove 24 to be separated from the cavity of the shell 20;

[0038] In summary, by providing the flipping rod 37, the activity of the pagoda vegetable in the cavity of the screen cylinder 25 can be improved, thereby improving the screening efficiency of the device and reducing the screening time.

[0039] A medicinal material harvester, not shown in the figure, includes a harvester body, including all the combined screen structures mentioned above, and a shell 20 is installed in the cavity of the harvester body.

[0040] By setting up this scheme, the medicinal material harvester can have the best working efficiency even under long-term working conditions, and the working time can also be reduced.

[0041] Working principle: Pour the pagoda leaves to be screened from the feed pipe 21 and turn on the power. After entering the feed pipe 21, the pagoda leaves will enter the cavity of the sieve cylinder 25 in the cavity of the shell 20 along with the cavity of the feed pipe 21. The rotating sieve cylinder 25 will drive the pagoda leaves to turn in its cavity so that the soil is separated from the wall of the pagoda leaves. The separated soil will pass through the sieve hole 26. When the sieve cylinder 25 rotates, it will drive the trigger block 36 to rotate at the same time. The bottom of the top rod 33 at the corresponding position will contact along the top wall of the trigger block 36, and the trigger block 36 will push the top rod 33 When pushed to the highest point of the spring groove 31, the spring plate 32 will be driven by the push rod 33 to move in the spring groove 31. When the push rod 33 drives the spring plate 32 to move upward, the spring at the top of the spring plate 32 will be compressed. After the bottom of the push rod 33 stops and contacts the wall of the trigger block 36, the spring will push the trigger block 36 downward. The push rod 33 will drive the hitting rod 34 to move downward. The hitting rod 34 can quickly contact the top of the screen drum 25 to vibrate out the soil stuck in the sieve hole 26 to prevent blockage. After the discharge plate 23 is flipped upward, the pagoda vegetable will detach from the device at the discharge trough 22.

[0042] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
