Description

Technical Field

[0001] This utility model relates to the field of moxa stick processing technology, specifically a raw material screening device. Background Technology

[0002] The sieving process for moxa sticks primarily removes impurities from the mugwort leaves, separating the mugwort floss and mugwort powder. Mugwort floss is the main raw material for making moxa sticks, while mugwort powder can be used to make other mugwort products, such as moxa patches and umbilical patches, or as a feed additive and veterinary medicine. Sieving ensures the purity and quality of the moxa sticks.

[0003] When sieving, the mugwort leaves should be evenly spread on the sieve and sieved with appropriate force to ensure that the mugwort leaves can pass through the sieve smoothly;

[0004] In existing technologies, the screening of mugwort leaves typically involves directly feeding the leaves onto a screen using a feeding device. This method cannot guarantee that the leaves are evenly distributed on the screen, and impurities mixed in with the piled leaves are difficult to remove, requiring a longer screening time to achieve the desired screening effect. Therefore, a raw material screening device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material screening device that has advantages such as the ability to spread the screened mugwort leaves evenly, thus solving the problem of poor screening effect of mugwort leaves in traditional technologies.

[0007] The support frame is provided with a transmission component for transmission. The transmission component includes a transmission motor. The output shaft of the transmission motor is fixedly connected to a transmission wheel. A transmission belt is provided on the transmission wheel. The transmission belt is driven by a driven component. The driven component is driven by the screening frame.

[0008] The tiling assembly includes a connecting frame, which includes two support rods and a connecting rod. The two support rods are fixedly connected to both sides of the mounting frame. Multiple tiling straight rods are fixedly connected to the bottom of the connecting rod, and tiling crossbars are provided on the multiple tiling straight rods.

[0009] Furthermore, the driven component includes two support platforms for support, both of which are fixedly connected to the mounting frame. Rotary bearings are provided inside the two support platforms, and a connecting shaft is rotatably connected inside each of the two rotary bearings. A driven wheel is fixedly connected to the rod portion of the connecting shaft.

[0010] Furthermore, the driven wheel and the transmission wheel are tensioned and connected by the transmission belt.

[0011] Furthermore, one end of the connecting shaft is fixedly connected to a transmission arm for transmission, the other end of the transmission arm is rotatably connected to a connecting arm, and the other end of the connecting arm is rotatably connected to the screening frame.

[0012] Furthermore, the mounting frame is also provided with a hopper for discharging debris, and the hopper is inclinedly disposed below the screening frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] I. This raw material screening device, by setting up a flattening component, can effectively achieve the effect of flattening the mugwort leaves in the screening frame during use, thereby ensuring the working efficiency of the screening frame in the process of screening mugwort leaves, avoiding the inability to screen impurities due to the stacking of mugwort leaves, which would affect the screening effect, or require a longer screening time and increase screening costs.

[0023] As a preferred technical solution in this embodiment: In actual use, when it is necessary to screen the mugwort leaves, the worker can first use the feeding device to transport the mugwort leaves into the screening frame 13. Then, the worker can control the transmission component 3 to drive the driven component 4 to make the screening frame 13 move horizontally back to its original position. At this time, the support roller 12 located at the bottom of the screening frame 13 can provide good support for the screening frame 13 while ensuring that the screening frame 13 slides more smoothly. When the screening frame 13 moves horizontally back to its original position, the flat bar 22 can achieve the effect of leveling the stacked leaves. The multiple flat crossbars 23 provided on the flat bar 22 can further level the mugwort leaves from another direction, effectively ensuring the efficiency of screening the mugwort leaves and increasing its screening effect.

[0024] The technical effects of the above embodiments are as follows: by setting up the flattening component 2, it can effectively achieve the effect of flattening the mugwort leaves in the screening frame 13 during use, thereby ensuring the working efficiency of the screening frame 13 in the process of screening mugwort leaves, avoiding the problem that the impurities mixed in the mugwort leaves cannot be screened due to stacking of mugwort leaves, which would affect the screening effect or require a longer screening time and increase the screening cost.

[0025] Example 2:

[0026] Please see Figure 1-3 To achieve the effect of sieving the mugwort leaves, the driven component 4 in this embodiment includes two support platforms 41 for support. Both support platforms 41 are fixedly connected to the mounting frame 11. Rotary bearings are provided inside the two support platforms 41, and connecting shafts 43 are rotatably connected to both rotating bearings. A driven wheel 42 is fixedly connected to the rod part of the connecting shaft 43. A transmission belt 33 is tensioned between the driven wheel 42 and the transmission wheel 32. A transmission arm 44 for transmission is fixedly connected to one end of the connecting shaft 43, and a connecting arm 45 is rotatably connected to the other end of the transmission arm 44. The other end of the connecting arm 45 is rotatably connected to the sieving frame 13. A discharge hopper 14 for discharging impurities is also provided on the mounting frame 11. The discharge hopper 14 is inclinedly arranged below the sieving frame 13.

[0027] As a preferred technical solution in this embodiment: In actual use, when the staff needs to sieve the mugwort leaves, the transmission motor 31 can be controlled to drive the transmission wheel 32 to rotate. During the rotation of the transmission wheel 32, the transmission belt 33 can drive the driven wheel 42 to rotate. During the rotation of the driven wheel 42, the transmission arm 44 can rotate. During the transmission of the transmission arm 44, its other end can drive the connecting arm 45 to move horizontally. During the displacement of the connecting arm 45, the screening frame 13 can be effectively moved horizontally. During the continuous rotation of the transmission arm 44, the screening frame 13 can be effectively driven to reciprocate horizontally, thereby achieving the effect of sieving the mugwort leaves. The impurities sieved from the mugwort leaves can fall onto the hopper 14 for discharge.

[0028] The technical effects brought about by the above embodiments are as follows: by setting the transmission component 3, it can achieve a good transmission effect during use; by setting the driven component 4, it can drive the connecting arm 45 through the rotation of the transmission arm 44 during use, so that the screening frame 13 can move horizontally back and forth, thereby ensuring the screening effect of the screening frame 13 on the mugwort leaves.

[0029] The working principle of the above embodiments is as follows:

[0030] I. In actual use, when it is necessary to screen mugwort leaves, the staff can first use the feeding device to transport the mugwort leaves into the screening frame 13. Then, the staff can control the transmission component 3 to drive the driven component 4 to make the screening frame 13 move horizontally back to its original position. At this time, the support roller 12 at the bottom of the screening frame 13 can provide good support for the screening frame 13 and ensure that the screening frame 13 slides more smoothly. When the screening frame 13 moves horizontally back to its original position, the flat bar 22 can achieve the effect of leveling the stacked leaves. The multiple flat crossbars 23 set on the flat bar 22 can further level the mugwort leaves from another direction, effectively ensuring the efficiency of screening mugwort leaves and increasing its screening effect.

[0031] II. In actual use, when the staff needs to screen the mugwort leaves, they can first control the transmission motor 31 to drive the transmission wheel 32 to rotate. During the rotation of the transmission wheel 32, the transmission belt 33 can drive the driven wheel 42 to rotate. During the rotation of the driven wheel 42, the transmission arm 44 can rotate. During the transmission of the transmission arm 44, its other end can drive the connecting arm 45 to move horizontally. During the displacement of the connecting arm 45, the screening frame 13 can be effectively moved horizontally. During the continuous rotation of the transmission arm 44, the screening frame 13 can be effectively driven to reciprocate horizontally, thereby achieving the effect of screening the mugwort leaves. The impurities screened out from the mugwort leaves can fall onto the feed hopper 14 for discharge.
