Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0028] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1-5 As shown, this utility model provides an integrated putty mixing and grinding device, characterized in that it includes: a machine body 10, a grinding device 40 inside the machine body 10, a discharge port 44 on one side of the grinding device 40, a material bucket 30 above the machine body 10, the bottom of the material bucket 30 communicating with the grinding device 40, a mixing device 20 inside the material bucket 30, and a valve 31 at the connection between the material bucket 30 and the grinding device 40. The putty powder in the material bucket 30 is mixed by the mixing device 20 and then enters the grinding device 40 for grinding.

[0030] Specifically, wheels 11 are provided on both sides of the bottom of the machine body 10, with at least one wheel 11 being a swivel wheel and the other wheel 11 being a fixed wheel. The swivel wheel has shock absorption and braking functions, and the brake can be released during transportation and locked when stopped. The structure of the swivel wheel is existing technology and will not be described in detail here. A frame 12 is also provided on the top of the machine body 10, and a handle 13 is provided on the same side of the frame 12 and the swivel wheel to facilitate the operator to push the machine body 10. A material hopper 30 is fixed on the top of the machine body 10 and on one side of the frame 12. The machine is equipped with a stirring device 20 for stirring the putty powder in the material bucket 30. The bottom of the material bucket 30 has an outlet for the stirred putty powder to flow out. The machine body 10 is also equipped with a grinding device 40. The input end of the grinding device 40 is connected to the bottom of the material bucket 30. In order to control the flow of putty powder, a valve 31 is also provided at the connection between the material bucket 30 and the grinding device 40. The flow of putty powder is controlled by the valve 31. The grinding device 40 has a discharge port 44. When the putty powder is stirred evenly, it flows into the grinding device 40, and after being ground by the grinding device 40, it flows out from the discharge port 44.

[0031] To prevent putty powder from accumulating at the bottom of the material bucket 30 and being unable to flow out, the bottom of the material bucket 30 is set with a predetermined slope towards the center, so that the putty powder can flow into the grinding device 40 from the outlet at the bottom of the material bucket 30 more effectively.

[0032] The mixing device 20 includes: a mixing motor 21, which is fixedly connected to the frame 12; a mixing fixing device 22 is connected to the output end of the mixing motor 21, which is also fixedly connected to the frame 12 for positioning and to counteract the swaying force generated by the mixing device 20 during operation, thereby reducing impact and extending service life; a power output end 23 is provided at the end of the mixing fixing device 22 away from the mixing motor 21, which is driven by the mixing motor 21 to rotate; a mixing shaft 24 is also connected to the power output end 23, which is located inside the material tank 30. At least two central stirring paddles 25 are provided in the middle section. The number of central stirring paddles 25 can be increased according to actual needs. To avoid the central stirring paddles 25 from contacting the material bucket 30, the sides of the central stirring paddles 25 are spaced apart from the inner wall of the material bucket 30. Since the stirring force on the outer side of the central stirring paddles 25 is strong when rotating, while the stirring force on the side adjacent to the stirring shaft 24 is weak, in order to avoid the central stirring paddles 25 being covered by putty due to the weak stirring force, which would affect the stirring effect, a bottom stirring paddle 26 is also provided at the end of the stirring shaft 24 away from the power output end 23. The width of the bottom stirring paddle 26 is less than or equal to half the length of the central stirring component, so that it is used to stir the putty in the middle and improve the stirring effect. In this embodiment, the bottom of the material bucket 30 has a sloping transition. To enable the central stirring paddle 25 to better stir the putty located at the bottom, the central stirring paddle 25 is preferably inverted and anchor-shaped. Since the side of the central stirring paddle 25 is spaced from the inner wall of the material bucket 30, to prevent the putty from accumulating in the inner wall of the material bucket 30, the side of the central stirring paddle adjacent to the inner wall of the material bucket 30 can be adjusted with scrapers 27. The scrapers 27 are made of flexible material, giving them a certain degree of flexibility. During assembly, the distance between the scrapers 27 and the inner wall of the material bucket 30 can be adjusted. In this embodiment, the distance is adjusted to slightly contact the inner wall of the material bucket 30. This design can reduce the impact of the non-circular diameter of the material bucket 30 and prevent the putty from accumulating on the bucket wall.

[0033] It should be noted that a lid can be added to the top of the material bucket 30 as needed. Under normal circumstances, the speed of the mixing motor 21 is set to the speed at which the putty cannot overflow from the material bucket 30 during mixing. If it is necessary to increase the mixing efficiency and increase the speed, a lid can be added to prevent the putty from overflowing. In addition, the top of the material bucket 30 is also provided with a horizontally extending baffle that can limit the putty from overflowing from the material bucket 30 at normal speeds.

[0034] The grinding device 40 includes: a grinding frame 41, which is fixedly connected to the machine body 10. A grinding element 43 is connected to the top of the grinding frame 41. The input end of the grinding element 43 is connected to the outlet at the bottom of the material bucket 30, and a valve 31 is provided at the connection. When the mixing process is underway, the valve 31 can be used to restrict the flow of putty powder in the material bucket 30. After the mixing is completed, the valve 31 can be opened to allow the putty powder to flow out and enter the grinding device 40. A grinding motor 42 is also fixedly provided on one side of the grinding frame 41. The output end of the grinding motor 42 is connected to the bottom end of the grinding element 43. The grinding motor 42 drives the grinding element 43 to rotate to grind the putty powder inside. When the required level is reached, the putty powder is discharged from the discharge port 44. The grinding element 43 adopts existing conventional technology, so it will not be described in detail here.

[0035] It should be noted that the discharge port 44 is also connected to a filter device 45, which is used to filter larger particles in the putty to ensure that the discharged putty is fine. At the same time, it increases the height of the discharge port 44 from the ground. The filter device 45 can be a filter screen covering the discharge port 44 or other structures with filtering functions.

[0036] Since the working environment is not entirely flat, in order to prevent the machine body 10 from shaking due to stirring when working on uneven ground, the machine body 10 can also be equipped with a ground support to support the machine body 10 and reduce shaking. The ground support is existing technology, so it will not be described in detail here.

[0037] During operation, the mixing motor 21 has low-speed and high-speed settings. First, clean water and putty powder are poured into the material bucket 30. The mixing motor 21 is turned on at low speed to drive the middle mixing paddle 25 and the bottom mixing paddle 26 to rotate and mix the putty powder in the material bucket 30. After initial mixing, the mixing motor 21 enters the high-speed setting. To ensure that the putty powder is fully mixed, the mixing motor 21 pauses for a moment after each mixing for a certain period of time and then restarts mixing or reverses the mixing. This cycle is repeated. After mixing is completed, the valve 31 is opened and the grinding motor 42 is started to grind the putty that has entered the grinding part 43. After grinding, the putty is squeezed out from the discharge port 44.

[0038] During the material discharge process, if only the putty powder itself is used, the poor fluidity of the putty powder will result in slow discharge. However, the low speed of the mixing motor 21 can promote the discharge at this time.

[0039] In summary, this application integrates mixing and grinding into one unit, allowing for grinding after mixing, thus improving work efficiency. It is also mechanized, eliminating the need for manual mixing and reducing labor intensity. The combination of low and high speeds of the mixing motor 21 reduces splashing, improves mixing efficiency and quality, and increases the speed at which putty flows out of the material bucket 30 during the discharge process. The overall structure is simple, low-cost, easy to move, and convenient for widespread use.

[0040] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
