When the stirring main shaft rotates, the plurality of stirring shoes will realize circular motions of different radii, thereby realizing uniform heating and stirring of the asphalt concrete material. However, the current connection method between the mounting rod and the stirring support disk is generally welding or bolt connection, which is easy to loosen when the mounting rod rotates at a high speed for a long time, thereby causing the mounting rod to fall off. Therefore, a new type of vertical mixing kettle stirring shaft installation and positioning structure is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0024] The present embodiment provides a positioning structure, which is mainly used to solve the problem that the current installation method between the stirring support plate and the mounting rod of the stirring device of the vertical stirring kettle is connected by bolts, and the threaded connection is easy to loosen when the stirring support plate rotates, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0025] A positioning structure comprises: a stirring spindle 1 with a stirring support plate 2 arranged at the bottom. When in use, the user first inserts a plurality of mounting rods 4 into the inner wall of the stirring support plate 2, slides a plurality of limit blocks 5 into the surface of the stirring support plate 2, and then slides them into the surfaces of the plurality of mounting rods 4 in sequence, and then installs one end of the stirring spindle 1 on the surface of the stirring support plate 2 through the mounting mechanism 3, so that one end of the stirring spindle 1 is in contact with the surfaces of the plurality of limit blocks 5, thereby realizing the limiting of the plurality of limit blocks 5, and one end of the plurality of mounting rods 4 is provided with stirring shoes 6. When in use, the user can realize the disassembly and assembly of the plurality of stirring shoes 6 on one end of the plurality of mounting rods 4 through the connecting mechanism 7, wherein the main components of the mounting mechanism 3 are: a first protrusion 301 fixedly mounted on the surface of the stirring spindle 1, and the first protrusion 301 is slidably inserted into the top of the stirring support plate 2. When in use, the user inserts an insertion rod 302 into the surfaces of the stirring support plate 2 and the first protrusion 301 in sequence, and then realizes the positioning of the insertion rod 302 through the first limiting mechanism 8. By limiting the inner wall of the stirring support plate 2 and the first protrusion 301, the connection between the stirring support plate 2 and the stirring main shaft 1 can be realized. Compared with the traditional method of directly connecting the stirring support plate 2 and the stirring main shaft 1 together by bolts, the force point of the gravity of the stirring support plate 2 is no longer directly applied to the threaded connection, but is applied to the surface of the insertion rod 302 and the first protrusion 301. The first limiting mechanism 8 only limits the relative position of the insertion rod 302 and the stirring support plate 2, further improving the overall stability of the device. The main components of the connecting mechanism 7 are: a plurality of stirring shoes 6, and a connecting rod 701 is fixedly installed at one end of a plurality of mounting rods 4. When in use, the user can respectively install a plurality of stirring shoes 6 on one end of a plurality of connecting rods 701 through the second limiting mechanism 9. At the same time, a plurality of crushing grooves 702 are opened on the surface of a plurality of connecting rods 701. When the stirring main shaft 1 drives the plurality of connecting rods 701 to rotate, the plurality of crushing grooves 702 will crush large pieces of material for subsequent stirring operations.

[0026] The stirring support plate 2 is arranged under the stirring main shaft 1, so that when in use, the user needs to first slide the plurality of mounting rods 4 into the inner wall of the stirring support plate 2, and then slide the plurality of limit blocks 5 into the surface of the stirring support plate 2, and at the same time make the plurality of limit blocks 5 slide into the surface of the plurality of mounting rods 4, and finally install one end of the stirring main shaft 1 on the surface of the stirring support plate 2 through the mounting mechanism 3. The plurality of mounting rods 4 can be limited in position inside the stirring support plate 2 by the blocking effect of the stirring main shaft 1 on the plurality of limit blocks 5. The traditional mounting method generally directly mounts the mounting rod 4 on the surface of the stirring support plate 2 through flanges and bolts. In this connection method, when the stirring main shaft 1 rotates, the threaded connections of the plurality of bolts are directly pulled by the centrifugal force. The present device is different. When the stirring main shaft 1 rotates, the mounting rod 4 will pull the limit blocks 5 to evenly distribute the force on the surface of the stirring support plate 2, thereby achieving the effect of evenly dispersing the force and improving the tightness of the connection between the mounting rod 4 and the stirring main shaft 1.

[0027] By setting up several connecting rods 701 of inconsistent lengths, the user can slide the second protrusions 901 at one end of several connecting rods 701 into the tops of several stirring shoes 6 respectively, and after fastening them with the second limiting bolts 902, the spatial heights of the several stirring shoes 6 are different, so that when the user controls the rotation of the stirring main shaft 1, the several stirring shoes 6 can stir materials at multiple levels in the spatial height, ensuring the stirring effect.

[0028] like Figure 2 and Figure 4 As shown, in some embodiments, the main components of the first limiting mechanism 8 are: two limiting nuts 802. When in use, the user inserts the two first limiting bolts 801 into the surface of the stirring main shaft 1 through a thread, and at the same time, the two first limiting bolts 801 are sequentially threaded into the surfaces of the stirring support plate 2 and the insertion rod 302, and then the two limiting screws are respectively threadedly sleeved on the surfaces of the two first limiting bolts 801, so as to realize the connection between the stirring main shaft 1 and the stirring support plate 2, wherein the main components of the second limiting mechanism 9 are: a plurality of second limiting bolts 902. When in use, the user slides a plurality of second protrusions 901 respectively arranged at one end of a plurality of connecting rods 701 into the surfaces of a plurality of stirring shoes 6, and then threadably inserts a plurality of second limiting threads into the surfaces of a plurality of stirring shoes 6, and then threadably inserts a plurality of second limiting threads into the surfaces of a plurality of second protrusions 901, so as to realize the installation of a plurality of stirring shoes 6 at one end of a plurality of connecting rods 701.

[0029] like Figure 2 and Figure 3As shown, in some embodiments, a taking groove 10 for taking the limit blocks 5 is provided on the top of the plurality of limit blocks 5. It should be noted that: on the basis of the above, an embodiment can be added, that is, the plurality of stirring shoes 6 are at different positions along the height direction, so that the lengths of the plurality of connecting rods 701 will also be different, so that when the plurality of connecting rods 701 rotate, the spatial heights that can be stirred by the plurality of stirring shoes 6 are also different, thereby fully stirring the multi-layered materials in the spatial height.

[0030] The working process of the present invention is as follows: first, the user slides several mounting rods 4 into the inner wall of the stirring support plate 2, slides several limit blocks 5 into the surface of the stirring support plate 2, and then slides them into the surfaces of several mounting rods 4 respectively, and then slides the first protrusion 301 at one end of the stirring main shaft 1 into the top of the stirring support plate 2, and slides several insertion rods 302 into the surfaces of the stirring support plate 2 and the first protrusion 301 in turn, and finally limits the insertion rod 302 by the first bolt and the first nut, thereby realizing the assembly of the entire device. Compared with the traditional bolt connection, this assembly method is more stable, and the threaded connection will not be directly subjected to force. The centrifugal force applied to the mounting rod 4 by the rotation of the main shaft will be evenly dispersed to the surface of the limit block 5 and the stirring support plate 2, and the gravity of the stirring support plate 2 will also be evenly distributed on the surface of the first protrusion 301 through the insertion rod 302. This method can greatly increase the overall stability of the device.

[0031] Secondly, the user can unscrew the plurality of second limiting bolts 902 and then pull the plurality of second protrusions 901 out of the tops of the plurality of stirring shoes 6 , thereby realizing the disassembly and assembly of the plurality of stirring shoes 6 .

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
