DETAILED DESCRIPTION

[0020] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific illustrations.

[0021] like Figure 1-Figure 3 As shown, a horizontal shearing and mixing device includes a bracket 4, a mixing barrel 6, a power assembly, an execution assembly and a chassis 21. The bracket 4 and the chassis 21 are welded by profiles, and the overall structure is high in strength, strong and durable. The bracket 4 is connected to the chassis 21. Specifically, legs 20 are welded at the four corners of the bottom of the bracket 4 to stably support the bracket 4 and raise the overall height of the bracket 4 to facilitate material discharge and sewage discharge. A weighing sensor 17 is connected between the legs 20 and the chassis 21 to weigh and measure the materials during mixing, so as to facilitate accurate control of the material ratio used. The mixing barrel 6 is installed on the bracket 4, and the top of the mixing barrel 6 is processed into an open structure. Powder, clay, curing agent, water and other materials can be conveniently put into the mixing barrel 6 through the opening on the top of the mixing barrel 6. The power component is installed on one side of the bracket 4, and the execution component is installed in the mixing barrel 6. The power component is connected to the execution component by transmission, and the power component drives the execution component to rotate relative to the mixing barrel 6. During the rotation, the large-sized materials in the mixing barrel 6 are sheared and the materials are stirred. The power component and the execution component are connected in series on the mixing barrel 6 and installed and arranged on the same axis, with high transmission efficiency.

[0022] like Figure 1-Figure 3 As shown, the power assembly includes a driving motor 1, a reducer 2 and a mounting base 3. The mounting base 3 is bolted to one side of the mixing barrel 6. The reducer 2 is installed on the end face of the mounting base 3 away from the bracket 4. The driving motor 1 is connected to the end face of the reducer 2 facing away from the mounting base 3. The reducer 2 and the mounting base 3 as well as the driving motor 1 and the reducer 2 are connected by bolts. The connection is firm and reliable and easy to disassemble and assemble. After installation, the output end of the driving motor 1 is connected to the input end of the reducer 2 to realize power transmission.

[0023] like Figure 1-Figure 3 As shown, the actuator assembly includes a transmission shaft, a stirring tooth 8 and a shearing tooth 9. The transmission shaft is installed in the mixing barrel 6. Both ends of the transmission shaft pass through and extend outside the mixing barrel 6. The transmission shaft includes a driving shaft 5, a core shaft 7 and a supporting half shaft 10. The driving shaft 5, the core shaft 7 and the supporting half shaft 10 are welded in sequence and then integrally processed to ensure coaxiality. The driving shaft 5 is connected to the mounting seat 3. The driving shaft 5 is sleeved with a bearing. The bearing is located between the driving shaft 5 and the mounting seat 3. The end of the driving shaft 5 is connected to the reducer 2 for transmission. The reducer 2 drives the driving shaft 5 to rotate, and then drives the entire transmission shaft to rotate. A bearing seat 11 is installed on the side wall of the mixing barrel 6 away from the driving motor 1. The supporting half shaft 10 is connected to the mixing barrel 6 through the bearing seat 11.

[0024] At least two rows of stirring teeth 8 and at least two rows of shearing teeth 9 are connected to the circumferential surface of the core shaft 7, and each row of stirring teeth 8 and each row of shearing teeth 9 are arranged axially on the surface of the core shaft 7. Multiple rows of stirring teeth 8 are distributed in a circumferential array on the core shaft 7, and multiple rows of shearing teeth 9 are also distributed in a circumferential array on the core shaft 7. The stirring teeth 8 and the shearing teeth 9 are staggered on the core shaft 7. Shearing fixed teeth 14 are processed on the inner bottom end surface of the mixing barrel 6. The shearing fixed teeth 14 are arranged along the axial direction of the mixing barrel 6, and the shearing fixed teeth 14 correspond to the shearing teeth 9. Specifically, when the core shaft 7 drives the shearing teeth 9 to rotate to the position of the shearing fixed teeth 14, the shearing teeth 9 rotate relative to the shearing fixed teeth 14 to complete the shearing and crushing of large-sized materials and improve the mixing effect of the stirring teeth 8. The number of shearing teeth 9 is at least two rows. For each rotation of the core shaft 7, at least two shearing operations can be completed, which improves the shearing efficiency and greatly improves the mixing efficiency and mixing quality.

[0025] like Figure 1 and Figure 4 As shown, a discharge port 13 is connected to one end of the bottom of the mixing barrel 6 for discharging the slurry material after mixing. A discharge gate valve 12 is installed on the discharge port 13. After mixing, the discharge is realized by opening the discharge gate valve 12. A plurality of sieve holes 19 are processed on the circumferential side wall of the mixing barrel 6 above the discharge port 13. The sieve holes 19 penetrate the side wall of the mixing barrel 6. The qualified slurry material after mixing falls into the discharge port 13 through the sieve holes 19. A cleaning port 15 is connected to the end of the bottom of the mixing barrel 6 opposite to the discharge port 13. A cleaning gate valve 16 is installed on the cleaning port 15. After the slurry material is discharged, water can be added to the inside of the mixing barrel 6 for cleaning as needed. The slurry formed after cleaning is discharged from the cleaning port 15 by opening the cleaning gate valve 16.

[0026] like Figure 3 As shown, in order to prevent foreign matter from falling into the mixing barrel 6 during stirring, a protective net 18 is connected to the top of the mixing barrel 6. The protective net 18 adopts a mesh structure, that is, the protective net 18 is processed with meshes distributed in a rectangular array, so that the material can be put into the mixing barrel 6 through the meshes on the protective net 18, and the stirring situation in the mixing barrel 6 can be observed through the meshes. The size of the mesh is set according to specific needs.

[0027] The working principle of the utility model is:

[0028] When in use, first start the driving motor 1, and the driving motor 1 drives the driving shaft 5, the core shaft 7 and the supporting half shaft 10 to rotate relative to the mixing barrel 6 through the reducer 2. Various materials are quantitatively put into the mixing barrel 6 through the mesh on the protective net 18 in turn, and the amount of materials put in is measured by the weighing sensor 17. During the rotation of the core shaft 7, the stirring teeth 8 installed on the core shaft 7 stir the materials. When the core shaft 7 drives the shearing movable teeth 9 to rotate to the position of the shearing fixed teeth 14, the shearing movable teeth 9 rotate through the shearing fixed teeth 14 due to the staggered arrangement of the shearing movable teeth 9 and the shearing fixed teeth 14. When the teeth 14 are engaged, a shearing effect is exerted on the large-sized materials deposited at the bottom of the mixing barrel 6, thereby reducing the size of the materials, facilitating mixing, and improving the mixing efficiency and mixing quality. The multi-row distributed shearing teeth 9 enable the core shaft 7 to shear the materials multiple times each time it rotates one circle, thereby greatly improving the operating efficiency. After the mixing is completed, the slurry material passes through the sieve hole 19 and falls into the discharge port 13, and the discharge gate valve 12 is opened. The mixed slurry material is discharged through the discharge port 13, completing the mixing operation, realizing the functions of weighing, metering, mixing, etc., with stable and reliable operation, and overall transportation can be realized.

[0029] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
