[0034] See also Figures 1 to 7 The present invention provides a nutrient solution mixing and preparation device 100 for thoroughly mixing the raw materials and water required for preparing the nutrient solution to obtain the nutrient solution. The nutrient solution mixing and preparation device 100 includes a mixing drum 10, a rotating shaft 11, a drive motor (not shown), a filtering mechanism 12, a crushing mechanism 13, and a lifting mechanism 14.

[0035] The mixing drum 10 is the main structure of the nutrient solution mixing and modulation device 100 and also serves as a container for holding raw materials and water. The mixing drum 10 is provided with an inner cavity 101, a feed port 102, and a discharge port 103. Both the feed port 102 and the discharge port 103 are connected to the inner cavity 101, which is used to hold the mixture formed by the raw materials and water. During use, the operator adds the raw materials and water into the inner cavity 101 through the feed port 102. After the raw materials and water are evenly mixed in the inner cavity 101 to obtain the nutrient solution, the nutrient solution can be discharged from the inner cavity 101 through the discharge port 103.

[0036] The rotating shaft 11 is a generally cylindrical, long rod. It is rotatably disposed within the inner cavity 101. As a specific example, in this embodiment, the rotating shaft 11 is vertically inserted into the mixing drum 10. The bottom end of the rotating shaft 11 is inserted into the inner cavity 101 and rotatably connected to the bottom wall of the mixing drum 10. The top end of the rotating shaft 11 extends outside the mixing drum 10 and is configured to connect to the output shaft of the drive motor.

[0037] The drive motor is connected to one end of the rotating shaft 11 to drive the rotating shaft 11 to rotate. As a specific example, in this embodiment, the drive motor is arranged outside the mixing drum 10 and located at the top of the mixing drum 10, and the output shaft of the drive motor is connected to the rotating shaft 11 to drive the rotating shaft 11 to rotate.

[0038] The filter mechanism 12 is connected to the rotating shaft 11 and rotates with the rotation of the rotating shaft 11 to stir and mix the raw materials and water in the inner cavity 101. The filter mechanism 12 includes a filter hopper 121, which is used to filter and remove lumps from the mixed liquid during the rotation process. It should be noted that the above "filter hopper 121 is used to filter and remove lumps from the mixed liquid during the rotation process" means that the filter hopper 121 can filter out lumps from the mixed liquid during the rotation process and retain them within the filter hopper 121.

[0039] The crushing mechanism 13 is disposed in the filter hopper 121 , and is used to crush the agglomerates filtered and obtained by the filter hopper 121 , thereby eliminating agglomerates in the mixed liquid as much as possible.

[0040] The lifting mechanism 14 is provided between the filter mechanism 12 and the rotating shaft 11, and is used to drive the filter mechanism 12 to move axially along the rotating shaft 11. The lifting mechanism 14 can drive the filter mechanism 12 to move upward along the axial direction of the rotating shaft 11, and can also drive the filter mechanism 12 to move downward along the axial direction of the rotating shaft 11.

[0041] When the operator uses the above-mentioned nutrient solution mixing and modulation device 100 to prepare the nutrient solution, he first adds the raw materials and water into the mixing drum 10 from the feed port 102, and then starts the drive motor to drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the filtering mechanism 12 to rotate to achieve stirring of the raw materials and water. At the same time, the filtering mechanism 12 can also filter out the lumps in the mixed liquid obtained by mixing the raw materials and water and retain them in the filter hopper 121. The crushing mechanism 13 can crush the lumps in the filter hopper 121 to ensure that the raw materials and water are fully mixed. While the filtering mechanism 12 and the crushing mechanism 13 are working, the lifting mechanism 14 drives the filtering mechanism 12 to move along the axial direction of the rotating shaft 11, so that the filtering mechanism 12 can continuously move along the axial direction of the rotating shaft 11, thereby filtering the lumps at different heights in the inner cavity 101 and crushing them using the crushing mechanism 13.

[0042] Through the above-described configuration, the nutrient solution mixing and preparation device 100 can fully filter and crush lumps in the mixed solution within the inner cavity 101, thereby minimizing lumps in the mixed solution and ensuring that the raw materials and water are thoroughly mixed and stirred. Furthermore, because the nutrient solution mixing and preparation device 100 can crush lumps, the operator does not need to filter the mixed solution, which not only simplifies the nutrient solution preparation process, but also avoids raw material waste and improves the accuracy of the nutrient solution concentration.

[0043] See also Figures 2 to 4In some embodiments, the lifting mechanism 14 includes a rotating ring 141, a first clamping block 142 and a reciprocating thread groove 143. The reciprocating thread groove 143 is arranged on the outer peripheral wall of the rotating shaft 11. The rotating ring 141 is roughly annular in structure, and the rotating ring 141 is movably mounted on the rotating shaft 11. It should be noted that "the rotating ring 141 is movably mounted on the rotating shaft 11" means that the rotating ring 141 can rotate relative to the rotating shaft 11 and can move along the axial direction of the rotating shaft 11. The first clamping block 142 is fixedly arranged on the rotating ring 141 and is movably embedded in the reciprocating thread groove 143. The filter hopper 121 is connected to the rotating ring 141.

[0044] With the above arrangement, when the drive motor drives the rotating shaft 11 to rotate, the rotating ring 141 simultaneously rotates and moves along the axial direction of the rotating shaft 11 to one end of the rotating shaft 11, and then moves to the other end of the rotating shaft 11, repeating this cycle. As the rotating ring 141 rotates and moves along the axial direction of the rotating shaft 11, the filter hopper 121 also rotates and moves along the axial direction of the rotating shaft 11 with the rotating ring 141. This allows the filter hopper 121 to not only stir and mix the raw materials and water, but also filter and remove lumps in the mixed liquid so that the pulverizing mechanism 13 can fully pulverize the lumps.

[0045] See also Figures 4 to 6 In some embodiments, the filter mechanism 12 further includes a mounting frame 122 connected to the rotating ring 141. The mounting frame 122 can be integrally formed with the rotating ring 141, welded, or fixedly connected by fasteners such as bolts. The mounting frame 122 is a roughly rectangular frame, and the mounting frame 122 is provided with a mounting opening 1221. The mounting frame 122 has a first side 1222 and a second side 1223 that are opposite to each other. The filter hopper 121 includes a connected connecting frame 123 and a hopper body 124. The connecting frame 123 is a roughly rectangular frame, and the connecting frame 123 is connected to the mounting frame 122 and is located on the first side 1222. The hopper body 124 is passed through the mounting opening 1221 and extends to the second side 1223. The connecting frame 123 can be integrally formed with the mounting frame 122, welded, or fixedly connected by fasteners such as bolts. The hopper body 124 is provided with a filter tank 1241 for accommodating agglomerates, and the connecting frame 123 is provided with a clearance port 1231 communicating with the filter tank 1241 .

[0046] Through the above-mentioned arrangement, when the rotating ring 141 drives the mounting frame 122 to rotate, the mounting frame 122 drives the connecting frame 123 and the hopper body 124 to rotate synchronously. During the rotation of the hopper body 124, the mixed liquid containing agglomerates enters the filter tank 1241 of the hopper body 124. The agglomerates are filtered by the hopper body 124 and remain in the filter tank 1241. The liquid can pass through the hopper body 124, thereby filtering and obtaining the agglomerates.

[0047] In some embodiments, multiple mounting frames 122 are provided, evenly spaced along the circumference of the rotating shaft 11. The number of filter hoppers 121 is the same as the number of mounting frames 122, and the filter hoppers 121 are provided in a one-to-one correspondence with the mounting frames 122. As a specific example, in this embodiment, three mounting frames 122 and three filter hoppers 121 are provided. In other embodiments, the number of mounting frames 122 and the number of filter hoppers 121 can also be any number, such as two, four, or five.

[0048] See also Figures 4 to 7 In some embodiments, the hopper body 124 includes a first filter plate 1242, a second filter plate 1243, and two side plates 1244. Both the first filter plate 1242 and the second filter plate 1243 are provided with a plurality of filter holes 1245, enabling the hopper body 124 to filter out agglomerates. The first filter plate 1242 and the second filter plate 1243 are arranged at an angle and share a single common edge. It should be noted that "the first filter plate 1242 and the second filter plate 1243 are arranged at an angle" means that the first filter plate 1242 and the second filter plate 1243 intersect and do not overlap. As a specific example, in this embodiment, the angle between the first filter plate 1242 and the second filter plate 1243 is acute. The side plates 1244 are connected between the first filter plate 1242 and the second filter plate 1243, and the two side plates 1244 are spaced apart from each other along the radial direction of the rotating shaft 11. The first filter plate 1242 , the second filter plate 1243 and the two side plates 1244 together constitute the filter tank 1241 . The first filter plate 1242 , the second filter plate 1243 and the two side plates 1244 are all connected to the connecting frame 123 .

[0049] Through the above-mentioned arrangement, when the rotating ring 141 drives the mounting frame 122 to rotate, the mounting frame 122 drives the connecting frame 123 and the hopper body 124 to rotate synchronously. During the rotation of the hopper body 124, the mixed liquid containing agglomerates enters the filter tank 1241 of the hopper body 124, and the agglomerates are filtered by the first filter plate 1242 and the second filter plate 1243 and remain in the filter tank 1241. The liquid can be moved out of the filter tank 1241 from the filter holes 1245 on the first filter plate 1242 and the second filter plate 1243, so that the hopper body 124 can filter and obtain the agglomerates.

[0050] See also Figure 2 as well as Figures 4 to 7In some embodiments, the crushing mechanism 13 includes a first spring 131, a first extrusion member 132, a second spring 133, and a second extrusion member 134. The first extrusion member 132 is disposed in close contact with the first filter plate 1242, and the first spring 131 is connected between the connecting frame 123 and the first extrusion member 132. The second extrusion member 134 is disposed in close contact with the second filter plate 1243, and the second spring 133 is connected between the connecting frame 123 and the second extrusion member 134. As a specific example, in this embodiment, the first extrusion member 132 and the second extrusion member 134 are both long strip structures extending radially along the rotating shaft 11. In other embodiments, the first extrusion member 132 and the second extrusion member 134 can also be structures of any other shape, such as a block structure or a plate structure.

[0051] The nutrient solution mixing and modulation device 100 further includes a speed regulating mechanism 15, which is disposed within the inner cavity 101 and connected between the mixing drum 10 and the rotating ring 141. The speed regulating mechanism 15 is used to adjust the axial movement speed of the rotating ring 141 along the rotating shaft 11, thereby adjusting the rotation speed of the filter hopper 121. It should be noted that the speed regulating mechanism 15 can both increase and decrease the rotation speed of the filter hopper 121.

[0052] When the speed adjustment mechanism 15 increases the rotational speed of the filter hopper 121, the first extruding member 132 overcomes the elastic force of the first spring 131 and moves toward the common edge of the first and second filter plates 1242, 1243. The second extruding member 134 overcomes the elastic force of the second spring 133 and moves toward the common edge of the first and second filter plates 1242, 1243, thereby working together with the first extruding member 132 to squeeze the agglomerates within the filter tank 1241. When the speed adjustment mechanism 15 decreases the rotational speed of the filter hopper 121, the first extruding member 132 moves away from the common edge of the first and second filter plates 1242, 1243, while the second extruding member 134 moves away from the common edge of the first and second filter plates 1242, 1243. The first extruding member 132 and the second extruding member 134 separate, allowing them to collide with each other the next time the speed of the filter hopper 121 increases, thereby squeezing and crushing the agglomerates. Furthermore, when the rotation speed regulating mechanism 15 reduces the rotation speed of the filter hopper 121 , the liquid in the filter hopper 121 can also backwash the crushed agglomerates out of the filter hopper 121 so that the crushed agglomerates are fully mixed with water.

[0053] Through the above arrangement, since a speed regulating mechanism 15 is provided to regulate the speeds of the rotating ring 141 and the filter hopper 121, and the speed regulating mechanism 15 can increase or decrease the speed of the filter hopper 121, when the speed of the filter hopper 121 changes, the first extrusion member 132 and the second extrusion member 134 can continuously approach and separate, thereby squeezing and crushing the lumps in the filter hopper 121, and further allowing the raw materials and water to be fully mixed and stirred.

[0054] See also Figures 4 to 7 In some embodiments, a first guide bar 1246 and a second guide bar 1247 are disposed on opposing surfaces of both side panels 1244. The first guide bar 1246 is parallel to and spaced apart from the first filter plate 1242. The first extrusion member 132 is located between and in contact with the first guide bar 1246. The second guide bar 1247 is parallel to and spaced apart from the second filter plate 1243. The second extrusion member 134 is located between and in contact with the second guide bar 1247.

[0055] Through the above arrangement, the two first guide strips 1246 on the two side panels 1244 can limit and guide the first extrusion member 132, ensuring that the first extrusion member 132 always contacts the first filter plate 1242 and can only move along the surface of the first filter plate 1242. It should be noted that the surface where the first extrusion member 132 contacts the first filter plate 1242 and the surface where the first extrusion member 132 contacts the first guide strips 1246 are not the same surface; these two surfaces can be two mutually diverging surfaces of the first extrusion member 132. Therefore, the first guide strips 1246 can improve the stability of the movement of the first extrusion member 132, thereby ensuring that the first extrusion member 132 effectively crushes agglomerates. The two second guide strips 1247 on the two side panels 1244 can limit and guide the second extrusion member 134, ensuring that the second extrusion member 134 always contacts the second filter plate 1243 and can only move along the surface of the second filter plate 1243. It should be noted that the surface where the second extrusion member 134 contacts the second filter plate 1243 and the surface where the second extrusion member 134 contacts the second guide strip 1247 are not the same surface. The two surfaces may be two mutually diverging surfaces of the second extrusion member 134. Therefore, the second guide strip 1247 can improve the stability of the movement of the second extrusion member 134, thereby ensuring the lumps-breaking effect of the second extrusion member 134.

[0056] See also Figure 2 、 Figure 3 、 Figures 7 to 11In some embodiments, the mixing drum 10 has a top cover 104. The speed regulating mechanism 15 includes a limiting ring 151 and a damping adjusting assembly 152. The limiting ring 151 is roughly annular in structure, and the limiting ring 151 is movably mounted on the rotating shaft 11, and the limiting ring 151 is rotatably connected to the rotating ring 141. It should be noted that "the limiting ring 151 is movably mounted on the rotating shaft 11" means that the limiting ring 151 can move along the axial direction of the rotating shaft 11, and "the limiting ring 151 is rotatably connected to the rotating ring 141" means that the limiting ring 151 can rotate relative to the rotating ring 141, that is, during the rotation of the rotating ring 141, the limiting ring 151 may not rotate. As a specific example, in this embodiment, the limit ring 151 is composed of two relatively arranged half-ring structures, and the bottom of the limit ring 151 is sleeved on the top of the rotating ring 141, so that when the rotating ring 141 moves up and down along the axial direction of the rotating shaft 11, it can drive the limit ring 151 to move synchronously along the axial direction of the rotating shaft 11.

[0057] The damping adjustment assembly 152 is connected between the top cover 104 and the retaining ring 151 to provide movement resistance for the retaining ring 151. When the rotating ring 141 moves axially along the rotating shaft 11 toward the top cover 104, the retaining ring 151 moves synchronously with the rotating ring 141 toward the top cover 104. When the rotating ring 141 moves axially along the rotating shaft 11 away from the top cover 104, the retaining ring 151 moves synchronously with the rotating ring 141 away from the top cover 104. As the distance between the retaining ring 151 and the top cover 104 changes, the movement resistance provided by the damping adjustment assembly 152 to the retaining ring 151 also changes.

[0058] Through the above-mentioned setting, when the limiting ring 151 follows the rotating ring 141 to move along the axial direction of the rotating shaft 11 toward the top cover 104, the damping adjustment assembly 152 provides resistance for the limiting ring 151 and the rotating ring 141 in the direction away from the top cover 104, and as the distance from the limiting ring 151 to the top cover 104 changes, the magnitude of the above-mentioned resistance will also change, thereby changing the speed at which the limiting ring 151 and the rotating ring 141 move along the axial direction of the rotating shaft 11, and then changing the rotation speed of the rotating ring 141 and the filter hopper 121. Due to the change in the rotation speed of the filter hopper 121, the first extrusion member 132, the second extrusion member 134 cooperate with the first spring 131 and the second spring 133 to crush the lumps in the filter tank 1241, so that the raw materials and water can be fully mixed. Furthermore, when the damping adjustment component 152 reduces the rotation speed of the filter hopper 121 , the liquid in the filter hopper 121 can also backwash the crushed agglomerates out of the filter hopper 121 so that the crushed agglomerates are fully mixed with water.

[0059] In some embodiments, at least two first springs 131 are provided between each connecting frame 123 and the first extrusion member 132, with the at least two first springs 131 spaced apart. At least two second springs 133 are provided between each connecting frame 123 and the second extrusion member 134, with the at least two second springs 133 spaced apart. As a specific example, in this embodiment, two first springs 131 are provided between each connecting frame 123 and the first extrusion member 132, with the two first springs 131 located at either end of the first extrusion member 132. Two second springs 133 are provided between each connecting frame 123 and the second extrusion member 134, with the two second springs 133 located at either end of the second extrusion member 134. This arrangement improves the stability of the first spring 131 driving the first extrusion member 132, and also improves the stability of the second spring 133 driving the second extrusion member 134. In other embodiments, the first spring 131 and the second spring 133 may each be provided in any number, such as three, four, or five, and the number of first springs 131 and second springs 133 may be the same or different.

[0060] See also Figure 2 、 Figure 3 、 Figures 7 to 11 In some embodiments, the damping adjustment assembly 152 includes a damping cylinder 1521 , a damping rod 1522 , a compensation piston 1523 , a first piston 1524 , and a second piston 1525 .

[0061] The damping cylinder 1521 is a cylindrical structure with its axial direction parallel to the axial direction of the rotating shaft 11. A sealed inner cavity 1526 is defined within the damping cylinder 1521, one end of which is connected to the retaining ring 151. The damping rod 1522 is a generally round rod, one end of which is connected to the top cover 104, while the end of the damping rod 1522 facing away from the top cover 104 is inserted into the sealed inner cavity 1526. The damping rod 1522 is coaxially arranged with the damping cylinder 1521. The first piston 1524, the second piston 1525, and the compensating piston 1523 are all made of an elastic material, such as rubber or silicone. The first piston 1524 is connected to the end of the damping rod 1522 and is located in the sealed inner cavity 1526. The second piston 1525 is rotatably connected to and engages with the first piston 1524. The compensating piston 1523 is movably mounted on the damping rod 1522 and located within the sealed inner chamber 1526. It should be noted that the phrase "the compensating piston 1523 is movably mounted on the damping rod 1522" means that the compensating piston 1523 can move relative to the damping rod 1522 along the axis of the damping rod 1522. The compensating piston 1523 and the second piston 1525 separate the sealed inner chamber 1526 into a compensating air chamber 15261, a first liquid chamber 15262, and a second liquid chamber 15263. It is understood that the compensating air chamber 15261, the first liquid chamber 15262, and the second liquid chamber 15263 are all parts of the sealed inner chamber 1526. The compensating air chamber 15261 is located between the compensating piston 1523 and the damping cylinder 1521 and is filled with air. The first liquid chamber 15262 is located between the compensating piston 1523 and the second piston 1525. The second liquid chamber 15263 is located between the second piston 1525 and the damping cylinder 1521. The first piston 1524 is located in the first liquid chamber 15262. Both the first and second liquid chambers 15262 and 15263 are filled with damping fluid. The damping fluid can be a liquid with good viscosity, resistance, and lubricity, such as silicone oil or glycerin.

[0062] A first damping orifice 1527 is defined in first piston 1524, and a second damping orifice 1528 is defined in second piston 1525. At least a portion of the first damping orifice 1527 and at least a portion of the second damping orifice 1528 overlap axially with respect to damping rod 1522, thereby connecting first liquid chamber 15262 with second liquid chamber 15263. When second piston 1525 rotates relative to first piston 1524, the area of ​​the overlapping portion of first damping orifice 1527 and second damping orifice 1528 axially with respect to damping rod 1522 changes. The larger the area of ​​the overlapping part of the first damping hole 1527 and the second damping hole 1528 in the axial direction of the damping rod 1522, the smaller the movement resistance provided by the damping fluid to the limit ring 151 and the rotating ring 141. Conversely, the smaller the area of ​​the overlapping part of the first damping hole 1527 and the second damping hole 1528 in the axial direction of the damping rod 1522, the greater the movement resistance provided by the damping fluid to the limit ring 151 and the rotating ring 141. The second piston 1525 is provided with a second block 1529, and the inner side wall of the damping cylinder 1521 is provided with a spiral groove 1530, and the second block 1529 is embedded in the spiral groove 1530.

[0063] It should be noted that "at least part of the structure of the first damping hole 1527 overlaps at least part of the structure of the second damping hole 1528 in the axial direction of the damping rod 1522" means that the projection of the first damping hole 1527 in the axial direction of the damping rod 1522 and the projection of the second damping hole 1528 in the axial direction of the damping cylinder 1521 have at least a partial overlap. "When the second piston 1525 rotates relative to the first piston 1524, the area of ​​the overlapping portion of the first damping hole 1527 and the second damping hole 1528 in the axial direction of the damping rod 1522 changes" means that when the second piston 1525 rotates relative to the first piston 1524, the area of ​​the overlapping portion of the first damping hole 1527 in the axial direction of the damping rod 1522 and the projection of the second damping hole 1528 in the axial direction of the damping cylinder 1521 changes. The above technical effects can be achieved by setting the specific shapes of the first damping hole 1527 and the second damping hole 1528. As a specific example, in this embodiment, the first damping hole 1527 is roughly a rectangular through hole, and the second damping hole 1528 is roughly an arc-shaped through hole extending along the circumference of the damping rod 1522. The spacing between the two side surfaces of the second damping hole 1528 in the radial direction of the damping rod 1522 is continuously changing, and the spacing between the two opposite side walls of the second damping hole 1528 in the radial direction of the damping rod 1522 is smaller than the spacing between the two opposite side walls of the first damping hole 1527 in the radial direction of the damping rod 1522.

[0064] Through the above arrangement, when the limiting ring 151 follows the rotating ring 141 to move along the axial direction of the rotating shaft 11 toward the top cover 104, the damping cylinder 1521 will follow the limiting ring 151 to move toward the top cover 104, while the damping rod 1522 remains stationary. Therefore, the volume of the first liquid chamber 15262 will increase, and the volume of the second liquid chamber 15263 will decrease. The damping fluid in the second liquid chamber 15263 will sequentially pass through the second damping hole 1528 and the first damping hole 1527 into the first liquid chamber 15262, thereby providing the limiting ring 151 and the rotating ring 141 with a damping fluid. 1 provides movement resistance in the direction away from the top cover 104. In the above process, as the second piston 1525 moves along the axial direction of the damping cylinder 1521, the second block 1529 cooperates with the spiral groove 1530 to drive the second piston 1525 to rotate, thereby changing the area of ​​the overlapping portion of the second damping hole 1528 and the first damping hole 1527 in the axial direction of the damping rod 1522, thereby changing the movement resistance provided by the damping fluid to the limiting ring 151 and the rotating ring 141, thereby achieving adjustment of the rotation speed of the rotating ring 141 and the filter hopper 121. Similarly, when the limiting ring 151 follows the rotating ring 141 to move in the direction away from the top cover 104 along the axial direction of the rotating shaft 11, the damping cylinder 1521 will follow the limiting ring 151 to move in the direction away from the top cover 104, while the damping rod 1522 remains stationary, so the volume of the first liquid chamber 15262 will decrease, and the volume of the second liquid chamber 15263 will increase. The damping fluid in the first liquid chamber 15262 will pass through the first damping hole 1527 and the second damping hole 1528 in turn and enter the second liquid chamber 15263, thereby providing the limiting ring 151 and the rotating ring 141 with a certain degree of friction. It provides movement resistance in the direction close to the top cover 104, and in the above process, since the second piston 1525 moves along the axial direction of the damping cylinder 1521, the second block 1529 cooperates with the spiral groove 1530 to drive the second piston 1525 to rotate, thereby changing the area of ​​the overlapping part of the second damping hole 1528 and the first damping hole 1527 in the axial direction of the damping rod 1522, thereby changing the size of the movement resistance provided by the damping fluid to the limit ring 151 and the rotating ring 141, so as to achieve the adjustment of the rotation speed of the rotating ring 141 and the filter hopper 121. When the limiting ring 151 follows the rotating ring 141 to move along the axial direction of the rotating shaft 11 toward the top cover 104, the damping cylinder 1521 will move relative to the damping rod 1522 toward the top cover 104. At this time, the compensation piston 1523 will move along the axial direction of the damping rod 1522 toward the top cover 104 to compress the volume of the compensation air chamber 15261, and at the same time compensate for the overall volume change of the first liquid chamber 15262 and the second liquid chamber 15263.When the limiting ring 151 follows the rotating ring 141 to move along the axial direction of the rotating shaft 11 away from the top cover 104, the damping cylinder 1521 will move relative to the damping rod 1522 in the direction away from the top cover 104. At this time, the compensation piston 1523 will move along the axial direction of the damping rod 1522 away from the top cover 104 to increase the volume of the compensation air chamber 15261, and at the same time compensate for the overall volume change of the first liquid chamber 15262 and the second liquid chamber 15263.

[0065] To sum up, due to the provision of the limit ring 151 and the damping adjustment assembly 152, the rotation speed of the rotating ring 141 and the filter hopper 121 can be changed at any time, and then the rotation speed of the filter hopper 121 can be changed at any time, so that the first extrusion member 132 and the second extrusion member 134 cooperate with the first spring 131 and the second spring 133 to continuously crush the lumps in the filter tank 1241, so that the raw materials and water can be fully mixed.
