It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0035] Please also refer to Figures 1 to 10 , a concrete mixture mixing equipment provided by the present invention is now described. The concrete mixture mixing equipment comprises a mixing barrel 1, a mixing shaft 2 and a cover 3; one end of the mixing shaft 2 is connected to the output end of the driving motor, and the other end can be located in the mixing barrel 1; wherein, a first mixing blade 4 is connected to the outer peripheral wall of the mixing shaft 2; the cover 3 is sleeved on the mixing shaft 2; the cover 3 is used to buckle on the top of the mixing barrel 1; wherein, the cover 3 is formed by splicing two parts, and the outer peripheral wall of the cover 3 is detachably provided with a connecting part at the splicing position to connect the two parts of the cover 3. It should be noted that other structures of the mixing equipment not mentioned in this application are all existing technologies and will not be described here.
[0036] The present invention provides a concrete mixing device. Compared with the prior art, after placing the mixture into the mixing barrel 1, the two parts of the cover 3 are spliced to the top of the mixing barrel 1. The splicing position of the cover 3 has a through hole for the stirring shaft 2 to pass through. The edges of the two parts of the cover 3 are connected by a connecting component, which can prevent the two parts of the cover 3 from separating from each other during the mixing process. Through the above-mentioned arrangement of the present application, the material flying out of the mixing barrel 1 during the mixing process can be reduced, thereby reducing material waste. In normal use, the mixing barrel 1 is first placed in the working position, that is, the first stirring blade 4 on the stirring shaft 2 is located in the mixing barrel 1, and then the material is added to the mixing barrel 1.
[0037] Exemplarily, there is a plug-in structure between the two parts of the cover body 3, that is, one part has an insert plate 31 and the other part has a strip groove 32. After the two parts of the cover body 3 are spliced together, the insert plate 31 and the strip groove 32 are plugged in and matched, which can improve the sealing of the two parts of the insert plate 31.
[0038] In some embodiments, as Figures 1 to 10 As shown, the connecting component includes a connecting plate 5, which is provided with a plurality of through holes; both parts on the cover body 3 have threaded holes aligned with the connecting plate 5; the connecting component also includes a fixing bolt, the threaded end of the fixing bolt passes through the connecting plate 5 and is threadedly engaged with the cover body 3; the connecting plate 5 is an arc-shaped structure, and the connecting plate 5 is in contact with the outer peripheral wall of the cover body 3.
[0039] It should be noted that after the two parts of the cover body 3 are joined, the connecting plate 5 is placed on the outer peripheral wall of the cover body 3 and located at the joining position of the two parts of the cover body 3. Then, the two parts of the cover body 3 and the connecting plate 5 are connected by fixing bolts to fix the two parts of the cover body 3 together. By setting the connecting plate 5 in an arc-shaped structure, the contact area between the connecting plate 5 and the outer peripheral wall of the cover body 3 can be increased.
[0040] In some embodiments, as Figures 1 to 10 As shown, the two parts of the cover body 3 are each provided with a first slot 33 on the outer peripheral wall at the splicing location. The connecting component includes a connecting block 6, which has a plug-in portion 61 that plugs into the two first slots 33 to limit the two parts of the cover body 3 along the tangential direction of the splicing location. An elastic deformation layer is connected to the outer peripheral wall of the plug-in portion 61.
[0041] It should be noted that the first slots 33 on the two parts of the cover body 3 are set separately. After the two parts of the cover body 3 are spliced together, the two plug-in parts 61 on the connecting block 6 are respectively plugged into and matched with the two first slots 33 of the cover body 3, which can laterally limit the two parts of the cover body 3 and reduce the situation where the two parts of the cover body 3 are separated from each other.
[0042] In some embodiments, as Figures 1 to 10 As shown, the connecting component includes an insert 7. The outer peripheral wall of the joint between the two parts of the cover 3 has a second, interconnected slot 34, and the insert 7 engages with the second slot 34. The bottom of the second slot 34 has a third slot 35. The insert 7 has protrusions 71 on either side for engaging with the two third slots 35 to limit the position of the two parts of the cover 3 along the tangent direction of the joint. An elastic deformation layer is connected to the outer peripheral wall of the protrusion 71.
[0043] It should be noted that, since the second slots 34 on the two parts of the cover body 3 are connected to each other, the insert 7 can be inserted into the second slot 34; by setting the third slot 35 in the second slot 34, the two third slots 35 are not connected to each other, so after the two protrusions 71 are respectively plugged into the corresponding third slots 35, the two parts of the cover body 3 can be laterally limited to reduce the situation where the two parts are separated from each other.
[0044] In some embodiments, as Figures 1 to 10 As shown, a stirring disk 8 is provided at the bottom of the stirring barrel 1, the outer peripheral wall of the stirring disk 8 is in contact with the inner peripheral wall of the stirring barrel 1, and the stirring disk 8 rotates in cooperation with the stirring barrel 1; wherein, a plurality of second stirring blades 81 are provided at intervals along the circumference of the top of the stirring disk 8, and the stirring disk 8 has a limiting component connected to the stirring shaft 2.
[0045] It should be noted that the stirring disk 8 is connected to the stirring shaft 2 through a limiting component. During the rotation of the stirring shaft 2, the stirring disk 8 can be driven to rotate, and then the second stirring blade 81 stirs the material in the stirring barrel 1. Since the second stirring blade 81 is located at the bottom of the stirring barrel 1, the cooperation of the first stirring blade 4 and the second stirring blade 81 can make the material mixing more even.
[0046] In some embodiments, as Figures 1 to 10 As shown, the limiting component includes a connecting rod 82, the bottom end of the connecting rod 82 is connected to the center position of the stirring disk 8, and the top end is detachably connected to the stirring shaft 2; wherein, after the connecting rod 82 is connected to the stirring shaft 2, the stirring disk 8 can rotate along with the stirring shaft 2; the stirring shaft 2 has a socket, and the connecting rod 82 is plugged into the stirring shaft 2; wherein, the stirring shaft 2 is located outside the stirring barrel 1 and has a positioning hole 21, and the connecting rod 82 has a threaded hole aligned with the positioning hole 21; the stirring shaft 2 and the connecting rod 82 are connected by bolts.
[0047] It should be noted that when the mixing barrel 1 is installed in the working position, the first mixing blade 4 on the mixing shaft 2 is located inside the mixing barrel 1, the connecting rod 82 is plugged into the mixing shaft 2, and the threaded hole on the connecting rod 82 is aligned with the socket of the mixing shaft 2. At this time, the relative position of the connecting rod 82 and the mixing shaft 2 can be fixed by threading the bolt with the connecting rod 82.
[0048] Exemplarily, the two parts of the cover body 3 have half-sleeves 36 at the position of the stirring shaft 2. The two half-sleeves 36 can form a complete sleeve and be sleeved on the stirring shaft 2; the heads of the bolts on the stirring shaft 2 are all located in the sockets. After the cover body 3 is spliced, the sockets on the stirring shaft 2 are located in the sleeves of the cover body 3 to protect the sockets and reduce the amount of material entering the sockets.
[0049] In some embodiments, as Figures 1 to 10 As shown, the stirring disk 8 is an arc-shaped structure with the concave surface facing upward; the edge position of the top of the stirring disk 8 has a semi-chamfered corner 83.
[0050] It should be noted that by setting a semi-chamfer 83 at the edge position of the top of the stirring disk 8, after the stirring is completed, the material in the stirring barrel 1 is poured out. At this time, the material will adhere to the inner wall of the stirring barrel 1; by sliding the stirring disk 8 outward, the edge position of the stirring disk 8 can scrape the inner wall of the stirring barrel 1, and then scrape off the material on the inner wall of the stirring barrel 1, which is convenient for subsequent cleaning of the stirring barrel 1.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
