Description

Easy to control mixing rod

Technical field

The utility model belongs to the technical field of mechanical equipment, in particular to an easy-control stirring rod.

Background technique

In the concrete and paint construction process, the concrete or paint must be fully agitated using a blender and a pair of mixing rods to achieve uniform and fine mixing of the different components to meet construction requirements. Since the concrete mortar or coating is relatively viscous and the stirring rod must be operated at a lower speed, the mixer must provide sufficient torque to ensure the smooth operation of the mixing operation. Under this working condition, the operator holds The hands of the mixer are also subjected to the reaction torque of the same torque of the mixer. Because the mixing operation takes a long time to achieve the uniform mixing degree, the operator must support the reaction torque of the mixer torque in addition to the weight of the mixer. It is a very hard work. In addition, the ordinary stirring rod has only one fan blade. When the mixer drives the fan blade to rotate, the concrete or the paint is circulated in a single direction according to the principle of fluid mechanics under the thrust generated by the rotation of the fan blade, so that the efficiency of the mixing work is relatively low, and the stirring effect is low. Poor and long working hours.

In order to solve the problems existing in the prior art, people have conducted long-term exploration and proposed various solutions. For example, the Chinese patent document discloses a turbine agitator [application No.: 201310596005.0] including a stirring paddle including a central shaft, an impeller including a wheel disc, a blade, a bearing, and the outer ring of the wheel disc The blades are evenly disposed, and the turbine agitator includes at least one pair of impellers, each pair of impellers including an upper impeller and a lower impeller, the blades of the upper impeller are inclined upward, and the blades of the lower impeller are inclined downward; the central shaft is separately sleeved Independent of the upper and lower bearings of the wheel a hollow structure; the blades are inclined in the same direction with respect to the surface of the wheel; the blades of the upper impeller and the blades of the lower impeller are opposite to each other with respect to the surface of the wheel, and the impellers are disposed in pairs, and the upper and lower impellers of each pair of impellers tend to be opposite, and The blades on the impeller are opposite in direction to the wheel.

The above solution solves the problem that the stirring effect of the single impeller of the existing stirring rod is poor to some extent, and the stirring efficiency is improved to some extent, but the solution still cannot fundamentally solve the large reaction torque and the labor intensity when the stirring rod is used. The problem.

Utility model content

The purpose of the utility model is to provide an easy-to-operate stirring rod which is simple and reasonable in structure and can reduce or eliminate the reaction force when the stirring rod is used.

In order to achieve the above object, the utility model adopts the following technical solutions: the easy-to-operate stirring rod comprises a main rod, and at least one first impeller is arranged on the main rod, wherein the main rod is sleeved on the main rod. a tube having at least one second impeller disposed on the sleeve, the main rod being axially or axially movably coupled to the sleeve, and rotating when the first impeller and the second impeller are respectively driven by the main rod and the sleeve The first impeller and the second impeller can generate a reverse axial reaction force. When in use, a reverse axial reaction force can be generated between the first impeller and the second impeller, so that the reaction torque of the stirring rod can be greatly reduced or eliminated, and the working strength during use can be reduced.

The first blade has the same inclination direction as the second blade. When the main rod is rotated in the same direction as the casing, when the inclination direction of the first impeller and the second impeller are opposite, the mutually impinging force between the first impeller and the second impeller can also generate a counter-torque on the mixer. It is greatly reduced or even disappeared. Similarly, when the rotation direction of the main rod and the sleeve is opposite, since the first vane rotates with the main rod, the reverse torque direction is opposite to the rotation direction of the main rod, and the second on the sleeve The blade rotates with the casing, and the reverse torque direction is opposite to the rotation direction of the casing.

The forces that cancel each other can also greatly reduce or even eliminate the counter torque on the mixer.

Obviously, the structure can completely fix the main rod and the sleeve in a circumferential direction, so that the main rod and the sleeve are positioned in the axial direction and the circumferential direction.

In the above-mentioned easy-to-operate stirring rod, the resultant force of the axial reaction forces generated by the respective first impellers and the respective second impellers is zero or the resultant force direction is upward along the axial direction. That is, when the axial reaction force generated between the first impeller and the second impeller can cancel each other or interact with each other, an upward force can be generated, so that the stirring rod is very labor-saving.

In the above-mentioned easy-to-operate stirring rod, the number of the first impeller and the second impeller is one, the first impeller is disposed at an end of the main rod, and the second impeller is disposed at a sleeve close to One end of the first impeller. That is, the first impeller and the second impeller are disposed close to each other, which improves the effect of the interaction between the first impeller and the second impeller.

The second connecting section is fixedly connected to the sleeve, and the first connecting section, the intermediate section and the second connecting section are connected in a unitary structure, and the first connecting section and the second connecting section of each second blade are circumferentially dislocated. . Obviously, this structure improves the stirring effect.

In the above-mentioned easy-to-operate stirring rod, the length of the first connecting section is greater than the length of the second connecting section. This ensures that the second blade can be tilted at a sufficient angle.
