Description

Technical Field

[0001] This application relates to the technical field of mortar mixing, and more specifically, to a mortar mixer. Background Art

[0002] Mortar is a bonding substance used for bricklaying in construction. It is made by mixing a certain proportion of sand and cementitious materials with water. Dry-mixed mortar is a product that mixes raw materials other than water, transports them to the construction site in bags or bulk, and can be directly used after mixing with water. When making dry-mixed mortar, a mixing device is required to mix the raw materials. The patent document with the publication number CN215359137U in the prior art provides a dry-mixed mortar mixer. This device is provided with a heating pad for heating the cylinder body of the mixing cylinder, and cooperates with the heat generated by the friction of the material during mixing to dry the material, reduce the moisture in the material, make the material relatively dry after mixing, facilitate subsequent transportation, and facilitate accurate proportioning and mixing with water during subsequent construction use.

[0003] Regarding the above related technology, the inventor believes that since the device needs to pour the raw materials in the material box into the mixing cylinder in proportion for mixing, it makes the mixing work intermittent, and the working efficiency is low. Therefore, we propose a mortar mixer. Utility Model Content

[0004] In order to improve the problems proposed in the above background art, this application provides a mortar mixer, and adopts the following technical solutions:

[0005] A mortar mixer includes a support frame, on which a conveyor belt is fixedly installed. There are two storage bins fixedly connected to the support frame on the upper side of one end of the conveyor belt. The lower ends of the storage bins are fixedly connected with two discharge pipes. There is a receiving hopper rotatably connected to the support frame on the lower side of the other end of the conveyor belt. There is a guiding pipe fixedly connected to the support frame under the receiving hopper. One end of the guiding pipe is connected with a mixing chamber in a frustum shape. The mixing chamber is rotatably connected to the support frame, and a plurality of mixing plates are fixedly connected inside the mixing chamber. A motor is fixedly installed on the support frame, and the motor is used to drive the receiving hopper and the mixing chamber to rotate.

[0006] By adopting the above technical solutions, the materials in the storage bins are discharged onto the conveyor belt through the discharge pipes. The conveyor belt rotates to transport the materials to the receiving hopper. The motor drives the receiving hopper and the mixing chamber to rotate. The receiving hopper rotates to receive the materials and drives the materials to fall towards the small-mouth end. The materials are initially mixed when rolling on the receiving hopper, converge at the small-mouth end and then enter the mixing chamber through the guiding pipe. The mixing chamber rotates to make the materials fall while the mixing plates remix the falling materials. The mixed materials are discharged from the large-mouth end of the mixing chamber, and continuous material mixing can be achieved.

[0007] Optionally, a baffle is slidably connected to one side of the discharge pipe. A bolt is threadedly connected to the baffle, and the bolt is rotatably connected to the discharge pipe.

[0008] By adopting the above technical solution, a notch is provided on the side of the discharge pipe facing the baffle. The bottom of the discharge pipe is in contact with the conveyor belt. When the conveyor belt rotates, the material flows onto the conveyor belt through the notch. Rotating the bolt can adjust the height of the baffle, so as to change the discharge amount, and thus the mixing ratio can be adjusted according to different materials.

[0009] Optionally, multiple mixing plates are arranged in multiple groups, and each group is arranged at equal intervals in a ring shape.

[0010] By adopting the above technical solution, the mixing plates are arranged obliquely. When the mixing bin rotates, it drives the material to contact with multiple mixing plates. The rotation of the mixing plates makes the material fall without a fixed trajectory, realizing effective mixing of the material.

[0011] Optionally, a driving gear is fixedly connected to the output end of the motor. A gear ring A meshing with the driving gear is fixedly connected to the receiving hopper, and a gear ring B meshing with the driving gear is fixedly connected to the mixing bin.

[0012] By adopting the above technical solution, the motor drives the driving gear to rotate. The driving gear meshes with the gear ring A to drive the receiving hopper to rotate, and the driving gear cooperates with the gear ring B to drive the mixing bin to rotate.

[0013] Optionally, an annular seat is fixedly connected to the support frame. A plurality of rollers are rotatably connected to the gear ring A at equal intervals in a ring shape, and the rollers are in rolling contact with the annular seat.

[0014] By adopting the above technical solution, the rolling contact between the rollers and the annular seat provides support for the receiving hopper.

[0015] Optionally, a plurality of convex blocks are fixedly connected to the annular seat at equal intervals in a ring shape, and the rollers are in rolling contact with the convex blocks.

[0016] By adopting the above technical solution, when the rollers contact the convex blocks, they drive the receiving hopper to rise. After the rollers cancel the contact with the convex blocks, the receiving hopper descends, so that the receiving hopper shakes during the rotation process, preventing material accumulation and improving the mixing effect at the same time.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. After the materials are conveyed to the receiving hopper through the conveyor belt, the materials are preliminarily mixed during the process of falling in the receiving hopper. Subsequently, they converge at the small-mouth end and enter the mixing chamber through the guiding pipe. The mixing chamber and the mixing plate cooperate to drive the materials for re-mixing. The mixed materials are discharged from the large-mouth end of the mixing chamber, enabling the device to continuously mix materials and improve work efficiency.

[0019] 2. When the receiving hopper rotates, the rollers contact the bumps, causing the receiving hopper to vibrate intermittently. This can not only prevent the materials from accumulating on the receiving hopper and being unable to fall, but also further improve the mixing effect. Description of the Drawings

Detailed Embodiment

[0025] The following further elaborates on the present application with reference to the accompanying drawings of the specification.

[0026] Refer to Figures 1-4, this application includes a support frame 1, on which a conveyor belt 2 is fixedly installed. On the upper side of one end of the conveyor belt 2, there are two storage bins 3 fixedly connected to the support frame 1. At the lower end of the storage bin 3, two discharge pipes 4 are fixedly connected. On the lower side of the other end of the conveyor belt 2, there is a receiving hopper 7 rotatably connected to the support frame 1. Below the receiving hopper 7, there is a guiding pipe 8 fixedly connected to the support frame 1. One end of the guiding pipe 8 is connected to a mixing chamber 9 with a frustum-shaped structure. The mixing chamber 9 is rotatably connected to the support frame 1, and inside the mixing chamber 9, a plurality of mixing plates 10 are fixedly connected. On the support frame 1, a motor 11 is fixedly installed, and the motor 11 is used to drive the receiving hopper 7 and the mixing chamber 9 to rotate. The materials in the storage bin are discharged onto the conveyor belt through the discharge pipe. The conveyor belt rotates to transport the materials to the receiving hopper. The motor 11 drives the receiving hopper 7 and the mixing chamber 9 to rotate. The receiving hopper 7 rotates to receive the materials and drives the materials to fall towards the small-mouth end. When the materials roll on the receiving hopper 7, preliminary mixing is achieved. After converging at the small-mouth end, the materials enter the mixing chamber 9 through the guiding pipe 8. The mixing chamber 9 rotates while allowing the materials to fall, and at the same time, the mixing plates 10 remix the falling materials. The mixed materials are discharged from the large-mouth end of the mixing chamber 9, and continuous material mixing can be achieved.

[0027] Refer to Figure 2 , on one side of the discharge pipe 4, there is a baffle 5 slidably connected. A bolt 6 is threadedly connected to the baffle 5, and the bolt 6 is rotatably connected to the discharge pipe 4. On the side of the discharge pipe 4 facing the baffle 5, there is a notch. The bottom of the discharge pipe 4 is in contact with the conveyor belt. When the conveyor belt 4 rotates, the materials flow onto the conveyor belt 4 through the notch. By rotating the bolt 6, the height of the baffle 5 can be adjusted, so as to change the discharge amount, and thus the mixing ratio can be adjusted according to different materials.

[0028] Refer to Figure 3 , a plurality of mixing plates 10 are arranged in multiple groups, and each group is arranged at equal intervals in a ring shape. The mixing plates 11 are arranged obliquely. When the mixing chamber 9 rotates, it drives the materials to contact with the multiple mixing plates 11. The rotation of the mixing plates 11 makes the materials fall without a fixed trajectory, realizing effective mixing of the materials.

[0029] Refer to Figure 3 , the output end of the motor 11 is fixedly connected to a driving gear 12. On the receiving hopper 7, there is a gear ring A 13 fixedly connected and meshing with the driving gear 12. On the mixing chamber 9, there is a gear ring B 14 fixedly connected and meshing with the driving gear 12. The motor 11 drives the driving gear 12 to rotate. The driving gear 12 meshes with the gear ring A 13 to drive the receiving hopper 7 to rotate, and the driving gear 12 cooperates with the gear ring B 14 to drive the mixing chamber 9 to rotate.

[0030] Refer to Figure 4 , on the support frame 1, there is an annular seat 15 fixedly connected. A plurality of rollers 16 are rotatably connected at equal intervals in a ring shape on the gear ring A 13. The rollers 16 are in rolling contact with the annular seat 15, and the rolling contact of the rollers 16 with the annular seat 15 provides support for the receiving hopper 7.

[0031] Refer to Figure 4 Figure 4 , a plurality of bumps 17 are fixedly connected to the annular seat 15 at equal intervals in a ring shape. The roller 16 is in rolling contact with the bumps 17. When the roller 16 contacts the bumps 17, the material receiving hopper 7 is driven to rise. After the roller 16 cancels the contact with the bumps 17, the material receiving hopper 7 descends, so that the material receiving hopper 7 shakes during rotation, preventing material accumulation and improving the mixing effect at the same time.

[0032] The implementation principle of a mortar mixer according to an embodiment of the present application is as follows: Materials are respectively poured into the storage box 3. The conveyor belt 2 and the motor 12 rotate. The motor 11 drives the driving gear 12 to rotate. The driving gear 12 meshes with the gear ring A 13 to drive the material receiving hopper 7 to rotate. The driving gear 12 cooperates with the gear ring B 14 to drive the mixing chamber 9 to rotate. The conveyor belt 2 conveys the materials onto the material receiving hopper 7. The materials roll and mix on the material receiving hopper 7 and then flow into the mixing chamber 9 through the guiding pipe 8. The mixing chamber 9 cooperates with the mixing plate 10 to mix the materials again. The mixed materials are discharged through the large opening end of the mixing chamber 9.
