Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, and more specifically, it relates to a cement mixing device with dual mixing shafts. Background Technology

[0002] In the construction of small projects such as self-built houses and home decoration tiling in rural areas, the demand for cement mortar is not large. Usually, a hand-push cement mixer is placed on the construction site for use. The existing hand-push cement mixer is generally composed of a mounting base, mixing tank, mixing paddle, mixing motor, two rollers and push handle.

[0003] Existing application number: CN201922301578.1, this utility model discloses a cement mixer, the structure of which includes a mixing tank, a feed inlet, a fixed bracket, a rotating frame, a rotating wheel, a support rod, a handle, and a mixing drive connecting plate. This utility model's cement mixer, when cleaning is required after cement discharge, only needs to connect a water source, allowing water to flow through the water tank inside the mixing rod to the diversion conveying pipe on the spray block, so that the water flows into the water storage tank, flushing open the sealing blocks on the direct spray nozzle and the angled spray nozzle, causing the water to spray out in a dispersed manner. Simultaneously, the centrifugal force of the rotating mixing rod is used to throw the water onto the inner wall of the mixing tank, diluting and rinsing the cement adhering there. By improving the structure of the equipment, after the cement is mixed, processed, and discharged, the equipment can use the centrifugal force of the rotating rod to spray water to wash and clean the cement adhering to the inner wall of the mixing tank, preventing it from drying on the inner wall and affecting the volume of the mixing tank over time.

[0004] Based on the above, when a hand-push mixer needs to be moved, since it only has two rollers in the middle, the operator needs to lift the mixer handle to push it. When moving it, the operator not only needs to exert force back and forth but also needs to bear part of the weight of the mixer, which makes the labor intensity of the operator quite high. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cement mixing device with dual mixing shafts. This solves the problem that when existing hand-push mixers need to be moved, since they only have two middle rollers, the operator needs to lift the mixer handle to push it.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] First, when the mixer needs to be moved, turn on the support motor. Through the stabilizing support components, the rear roller slides down and the support components retract, so that the front and rear rollers support the ground at the same time. The mixer can be moved without lifting the push handle, making it easier to move. During the mixing operation, the rear roller is lifted up and the support components are supported, making the support of the mixing tank and the mounting base more stable.

[0045] Secondly, the dual-shaft mixing assembly allows the first and second mixing blades to rotate in opposite directions, enabling cement, sand, water, and other substances to mix together more quickly, resulting in higher mixing efficiency and better mixing effect for the finished cement mortar.

[0046] This invention utilizes the sliding descent of the rear rotor and the retraction of the support components to allow the front and rear rollers to simultaneously support the ground. Movement is easier and less strenuous without needing to lift the push handle. During mixing, the rear rotor is lifted, and the support components are raised, making the support of the mixing tank and mounting base more stable and preventing shaking during mixing, thus enhancing safety. The reverse rotation of the first and second mixing paddles effectively improves the mixing efficiency of the cement mortar. Attached Figure Description

[0086] The first driven bevel gear 1501 is coaxially fixedly connected to the upper end of the first lead screw 15. The first driven bevel gear 1501 meshes with the first driving bevel gear 14. The function of this is that the support motor 7 drives the first lead screw 15 to rotate through the bevel gear transmission mechanism formed by the meshing of the first driven bevel gear 1501 and the first driving bevel gear 14. The first lead screw 15 drives the roller shaft 16 and the two rear rollers 4 to move up and down through the threaded transmission mechanism formed by the roller shaft 16.

[0087] The stabilizing support components also include:

[0088] The second driving bevel gear 1502 is coaxially and fixedly connected to the lower end of the first lead screw 15.

[0089] The second lead screw 17 is rotatably connected to the bottom of the mounting base 1;

The second lead screw 17 drives the slider 18 to move left and right through the threaded transmission mechanism formed by the slider 18.

[0092] The stabilizing support components also include:

[0093] The first connecting shaft 19 is rotatably connected to the underside of the slider 18;

[0094] Connecting rod 20, two connecting rods 20 are provided, and the right ends of the two connecting rods 20 are respectively rotatably connected to the front and rear ends of the first connecting shaft 19;

The lower ends of the two support members 22 are rotatably connected to the left ends of the two connecting rods 20, respectively. The effect is that when the slider 18 slides to the right, it will pull the two support members 22 to rotate around the axis of the second connecting shaft 21 through the first connecting shaft 19 and the two connecting rods 20, thereby retracting the two support members 22.

[0097] The specific usage and function of this embodiment are as follows:

[0098] When it is necessary to move to the next location for construction, the support motor 7 is started. The support motor 7 drives the first lead screw 15 to rotate through the bevel gear transmission mechanism formed by the meshing of the first driven bevel gear 1501 and the first driving bevel gear 14. The first lead screw 15 drives the roller shaft 16 and the two rear rollers 4 to move downward through the threaded transmission mechanism formed by the roller shaft 16 and the roller shaft 16. After the two rear rollers 4 move to the bottom, they support the rear of the mounting base 1. At the same time as the first lead screw 15 rotates, it also drives the second driven bevel gear 1701 and the second driving bevel gear to rotate. The bevel gear transmission mechanism formed by the meshing of 1502 drives the second lead screw 17 to rotate. The second lead screw 17 drives the slider 18 to move to the right through the threaded transmission mechanism formed by the slider 18 and the slider 18. The slider 18 sliding to the right will pull the two support members 22 to rotate around the axis of the second connecting shaft 21 through the first connecting shaft 19 and the two connecting rods 20, thereby retracting the two support members 22, allowing the front roller 3 to fall to the ground, supporting the front of the mounting base 1. Then, the push handle 101 can be pushed to move the position, making it easier for the worker to push.
