The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0040] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 5 According to one embodiment of the present invention, a dredging agitator assembly includes a support 100, an agitator head 200, and a position adjustment device 400. The position adjustment device 400 is used to adjust the position of the support 100, such as adjusting the height and horizontal position of the support 100. The agitator head 200 is installed on the support 100. The position adjustment device 400 can move the support 100 and simultaneously move the agitator head 200.

[0042] In some embodiments of the present invention, the support 100 includes a volumetric cavity 110, which has an inlet 120. The volumetric cavity 110 is mainly used to collect sludge, which enters into the volumetric cavity 110 through the inlet 120. The sludge-clearing agitator assembly also includes a slurry pump 300, which is mounted on the support 100 and used to pump out the sludge from the volumetric cavity 110. (See reference...) Figure 1 , Figure 3 As shown, the inlet of the slurry pump 300 is located in the volume chamber 110, and the outlet of the slurry pump 300 can be connected to structures such as a sludge receiving device; the power of the slurry pump 300 can be set according to the volume of the sludge dredging agitator assembly.

[0043] The agitator head 200 is mounted on the bracket 100 and positioned close to the sludge inlet 120. The agitator head 200's movement carries the sludge to the sludge inlet 120, allowing it to enter the volumetric cavity 110 through the inlet 120. (Refer to...) Figure 1 , Figure 3 As shown, the agitator head 200 includes a spiral blade 210 and a drive device 220. The drive device 220 drives the spiral blade 210 to rotate, and the rotation of the spiral blade 210 can transport the sludge to the inlet 120. The outer peripheral edge of the spiral blade 210 is provided with a cutting groove 211, and the end of the spiral blade 210 is provided with a cleaning tooth 212. By providing the cutting groove 211 on the edge of the spiral blade 210 and the cleaning tooth 212 on the end of the spiral blade 210, the cleaning tooth 212 can effectively break up the hardened material in the sludge, and the cutting groove 211 can further improve the effect of the spiral blade 210 in cutting the hard material in the sludge, thereby improving the sludge removal effect and efficiency of the agitator head assembly.

[0044] In some embodiments of the present invention, the agitator head 200 further includes a main shaft 230, spiral blades 210 mounted on the main shaft 230, and a drive device 220 for driving the main shaft 230 to rotate around its own axis. The rotation of the main shaft 230 can drive the spiral blades 210 to rotate synchronously. Multiple spiral blades 210 are provided, all mounted on the main shaft 230 and spaced apart around the outer circumference of the main shaft 230. Specifically, refer to... Figure 1 , Figure 3 As shown, the drive device 220 is generally a rotary motor or similar device. The output end of the drive device 220 is connected to one end of the main shaft 230, and the drive device 220 can drive the main shaft 230 to rotate around its own axis. The main shaft 230 is generally a cylindrical rod-shaped structure. The cylindrical rod-shaped structure is simple to process and does not easily adhere to sludge. The helical blade 210 is installed on the outer circumferential surface of the main shaft 230 and is fixedly connected to the main shaft 230, for example, by welding or by fasteners. In this embodiment, the helical blade 210 is generally welded to the outer circumferential surface of the main shaft 230.

[0045] Furthermore, the agitator head 200 of this embodiment of the invention is provided with two helical blades 210. The two helical blades 210 are rotationally symmetrical about the central axis of the main shaft 230, and the angle of rotational symmetry between the two helical blades 210 is 180 degrees. The helical pitch of the helical blades 210 can be matched according to specific working conditions. For example, different helical blades 210 can be matched for different sludge materials to obtain the best sludge suction efficiency.

[0046] It is conceivable that the spiral blades 210 are not limited to two; they could also be one, three, four, etc. However, through simulation and analysis, two spiral blades 210 have higher suction efficiency and relatively lower manufacturing cost. The suction efficiency of one spiral blade 210 is insufficient for most scenarios. Setting more than two spiral blades 210 would increase the resistance to the rotation of the main shaft 230. At the same time, with more than two spiral blades 210, the distance between adjacent spiral blades 210 would decrease, which might actually lead to a decrease in suction efficiency. Therefore, for the spiral blades 210 in this embodiment, two spiral blades 210 are mainly used. If spiral blades 210 with different structures are used, the number of spiral blades 210 may need to be adjusted accordingly.

[0047] In some embodiments of the present invention, multiple cutting grooves 211 are provided, and the multiple cutting grooves 211 are spaced apart along the edge of the helical blade 210. (Refer to...) Figure 3 , Figure 5 As shown, the spiral blades 210 are spiral-shaped, and cutting grooves 211 are provided on the outer edges of both spiral blades 210. Generally, multiple cutting grooves 211 are evenly spaced on the edges of the spiral blades 210, but for certain special applications, non-uniformly spaced cutting grooves 211 can also be used. The cutting grooves 211 can effectively improve the ability of the spiral blades 210 to break up fixed waste or compacted materials in sludge.

[0048] In some embodiments of the present invention, the cross-sectional shape of the cutting groove 211 is generally rectangular, which has low processing cost and is easy to process. However, the cross-sectional shape of the cutting groove 211 is not limited to rectangular, but can also be semi-circular, trapezoidal or other shapes. The specific selection can be made according to the main components of the sludge and the application scenario.

[0049] In some embodiments of the present invention, the sludge-removing teeth 212 extend along the tangential direction of the helical blades 210. Specifically, refer to... Figure 5 As shown, the sludge-clearing teeth 212 are disposed on the end face of the bottom of the spiral blade 210, and multiple sludge-clearing teeth 212 are disposed at intervals along the length direction of the end face of the spiral blade 210. The sludge-clearing teeth 212 extend along the tangential direction of the spiral blade 210, that is, the end of the sludge-clearing teeth 212 is slightly lower than the end of the spiral blade 210, which facilitates the sludge-clearing teeth 212 in breaking up the hardened material in the sludge, and also facilitates the sludge to rise.

[0050] In some embodiments of the present invention, the ends of the sludge-clearing teeth 212 are made of a hard material; the ends of the sludge-clearing teeth 212 are conical. Specifically, refer to... Figure 5As shown, the hard material can be alloy steel or similar materials. The material at the end of the sludge-clearing tooth 212 must have a certain rigidity to reduce damage, and it should also have a certain degree of wear resistance. The main body of the sludge-clearing tooth 212 is generally cylindrical, while the end is generally conical. The conical end is more effective at breaking up hardened materials.

[0051] It is conceivable that the end of the dredging tooth 212 is not limited to a conical shape, but can also be a frustum, prism, wedge, or other structures.

[0052] In some embodiments of the present invention, the sludge removal tooth 212 is fixedly connected to the end face of the spiral blade 210, for example by welding or by means of fittings.

[0053] In some embodiments of the present invention, the bracket 100 includes a mounting plate 150, a drive device 220 mounted on the mounting plate 150, and a main shaft 230 rotatably mounted on the mounting plate 150 about its own axis. (See also...) Figure 1 , Figure 3 As shown, the mounting plate 150 can not only be used to mount the drive unit 220 and the spindle 230, but also effectively prevent the sludge from continuing to rise. The mounting plate 150 is provided with a mounting hole for one end of the spindle 230 to pass through. One end of the spindle 230 is inserted into the mounting hole and sealed to the mounting hole. There are various ways to seal the connection, such as using a mechanical shaft seal or adding a sealing cover.

[0054] In some embodiments of the present invention, a filter screen 130 and a clearing structure 140 are also included. The filter screen 130 is installed at the sludge inlet 120, and the clearing structure 140 is installed on the filter screen 130. The clearing structure 140 is used to prevent the filter screen 130 from becoming clogged. Specifically, the mesh size of the filter screen 130 is determined by the maximum particle volume that the slurry pump 300 can handle, thereby effectively preventing excessively large hard particles from jamming or damaging the slurry pump 300. The mesh of the filter screen 130 is arranged according to a certain pattern. By setting the filter screen 130 at the sludge inlet 120, the service life of the slurry pump 300 can be extended. The clearing structure 140 allows sludge to continuously enter the volume chamber 110, thereby ensuring the stable operation of the slurry pump 300.

[0055] Reference Figure 4As shown, the obstacle-clearing structure 140 in this embodiment of the invention includes a drive member 141, a scraper frame 142, and scrapers 143. The scraper frame 142 is mounted on the filter screen 130, and the scrapers 143 are rotatably mounted on the scraper frame 142. The drive member 141 is used to drive the scrapers 143 to rotate. The scraper frame 142 is circular and mounted on the filter screen 130. The drive member 141 is preferably a drive motor or other equipment, and is generally installed in the volume cavity 110. A central hole is provided at the center of the scraper frame 142. Three scrapers 143 are provided, and the three scrapers 143 are connected by a central member 144. The central member 144 is connected to the central hole through a connector, and the central member 144 is connected to the output end of the drive member 141. The drive member 141 can drive the central member 144 to rotate, thereby driving the three scrapers 143 to rotate synchronously. The three scrapers 143 are evenly spaced around the circumference, and the scrapers 143 and the central member 144 are preferably detachably connected. The scraper 143 has hard blades, and the drive 141 is preferably capable of driving the scraper 143 to rotate forward and backward; the rotation of the scraper 143 can effectively prevent the filter screen 130 from being blocked.

[0056] In some embodiments of the present invention, the position adjustment device 400 includes a first adjustment structure 410 and a second adjustment structure 420. The first adjustment structure 410 is used to drive the support 100 to move vertically, and the second adjustment structure 420 is used to drive the support 100 to swing horizontally. Specifically, the position adjustment device 400 includes a base frame 430 and a connecting rod 440. The base frame 430 is generally fixedly mounted on the robot and is connected to the support 100 via the connecting rod 440. The two ends of the first adjustment structure 410 are connected to the base frame 430 and the connecting rod 440, respectively. The base frame 430 is connected to the second adjustment structure 420, which is used to drive the base frame 430 to swing horizontally. The first adjustment structure 410 is a telescopic hydraulic cylinder. When the movable end of the first adjustment structure 410 extends, it can drive the support 100 to rise; when the movable end of the first adjustment structure 410 retracts, it can drive the support 100 to fall.

[0057] Reference Figure 2 As shown, the second adjustment structure 420 is a double-headed hydraulic cylinder, which can slide horizontally, thereby driving the base frame 430 to swing. Currently, most stirring head assemblies use a double-cylinder method to drive the stirring head 200 to swing horizontally. In this embodiment, the horizontal swing of the stirring head 200 is achieved using only a single double-headed hydraulic cylinder, simplifying the structure and reducing production costs. Through the actions of the first adjustment structure 410 and the second adjustment structure 420, the stirring head 200 can basically operate in multiple positions, expanding the application scenarios of the stirring head 200.

[0058] Reference Figures 1 to 5In another embodiment of the present invention, the robot includes the aforementioned dredging and stirring head assembly. The structure of the robot is not shown in the accompanying drawings; the dredging and stirring head assembly is generally mounted on one end of the robot. Since the robot includes the aforementioned dredging and stirring head assembly, it possesses at least all the beneficial effects of the dredging and stirring head assembly, which will not be elaborated upon here.
