Technical Field

The utility model relates to the field of concrete stirring equipment, in particular to a concrete stirring device.

Background

The concrete mixer replaces manual mixing by an iron shovel, and most manpower is saved. The existing concrete stirrers are divided into large stirrers, medium stirrers and small hand stirrers according to specifications, and medium stirrers are adopted for a large scale of construction sites or the building requirements of the people.

The prior medium-sized stirrer structure comprises a base, a stirring tank and a motor driving part, and four rollers are arranged on the base. Correspondingly, the outside of the stirring tank is provided with sliding grooves corresponding to the four rollers and a circle of gear teeth matched with the driving gear of the motor, the driving gear is meshed with the gear teeth, and the motor drives the stirring tank to rotate after being electrified.

In order to meet the strength requirement and the durability requirement, the stirring tank and the base are made of steel materials, and the stirring tank and the base are high in mass. In addition, the motor driving part not only has the weight of the motor, but also is provided with a reduction gear box, and further increases the weight, so that the total weight of the medium-sized stirrer is large. While the base is simply a rectangular frame, and the bottom is not provided with pulleys. If it is desired to move such a medium size stirrer, a crane is required. However, in a personal use or small-scale construction site, under the condition that no hoisting equipment is arranged, only four or more people can lift the middle-sized stirrer, so that the weight is excessive, and the waist is easily damaged. Therefore, the prior medium-sized stirrer is difficult to move by manpower and inconvenient to use.

Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs.

As shown in fig. 1, the present embodiment provides a concrete mixing apparatus including a base 1, a mixing tank 2, and a driving mechanism 3. The stirring tank 2 is rotatably connected to the base 1, the driving mechanism 3 is fixed to the base 1, and the driving mechanism 3 is in transmission connection with the stirring tank 2. For saving labor and being convenient to move, the base 1 is improved as follows:

The base 1 comprises four vertical upright posts 4, and the lower part of each upright post 4 is hinged with a lever through a hinge shaft 7. The lower end of each lever is provided with a rotatable roller, namely four rollers in total. Two of the four rollers are fixed wheels 5, and the other two rollers are universal wheels 6. The two fixed wheels 5 are located below the drive mechanism 3 and are subjected to a greater pressure than the universal wheels 6. The two universal wheels 6 cannot continue to rotate due to rotation limitation, namely, after the bracket of the universal wheel 6 rotates 45 degrees, the bracket touches the corresponding upright post 4, but can reversely rotate 90 degrees again. The left and right sides can deflect 45 degrees respectively, and most turning requirements are met.

As shown in fig. 1 and 2, a part of the lever between the hinge shaft 7 and the lower end of the lever in the present embodiment is a resistance arm 8, and a part of the lever between the hinge shaft 7 and the upper end of the lever is a power arm 9, and the length of the power arm 9 is 7 to 10 times the length of the resistance arm 8. When the concrete mixer does not need to move, all power arms 9 face upwards, and all rollers are suspended, so that the normal use of the concrete mixer is not affected. In this state, the rollers need to be kept suspended, so that two second limiting holes 10 are formed in each upright post 4, when the resistance arm 8 is horizontal, the two second limiting holes 10 are located on two sides of the power arm 9, and each second limiting hole 10 is provided with a second limiting bolt 17. This position is maintained by two second limit bolts 17 inserted into two second limit holes 10, respectively.

As shown in fig. 2, if movement is required, a power arm 9 is pulled outwards, so that the resistance arm 8 rotates 90 ° around the hinge shaft 7, and the roller is abutted against the ground. I.e. the corresponding upright 4 is jacked up and the lower end of the upright 4 is suspended. Each upright post 4 is provided with two first limiting holes 11, when the resistance arm 8 is vertical, the two first limiting holes 11 are positioned on two sides of the power arm 9, and each first limiting hole 11 is provided with a first limiting bolt. The position is maintained after the two first limit bolts are respectively inserted into the two first limit holes 11.

By the method, the other three upright posts 4 are sequentially rotated, and all the upright posts 4 are jacked up four times. Because only one upright post 4 needs to be jacked at a time, the required moment is small, and because the length of the power arm 9 is far longer than that of the resistance arm 8, the moment required by jacking the upright posts 4 is further reduced. Only one person is needed to operate the whole concrete stirring device, and only one person is needed to push the concrete stirring device to move after the concrete stirring device is jacked up, so that the difficulty of moving the concrete stirring device is greatly reduced, and the labor and time are saved.

In order to facilitate the application of force to the power arms 9, the power arms 9 of each lever are respectively bent toward the outside of the base 1. The included angle between the power arm 9 and the resistance arm 8 is 100-120 degrees. The bent lever can exert force better in the process of jacking up the base 1, and the use is more convenient.

As shown in fig. 3 and 4, in order to maintain smooth rotation of the fixed wheels 5, after the central shaft of each fixed wheel 5 passes through the mounting hole 12 of the corresponding upright 4, both ends of the central shaft are respectively locked by nuts 13; gaskets 14 are arranged between each fixed wheel 5 and the corresponding nut 13, between the fixed wheel 5 and the resistance arm 8 and between the resistance arm 8 and the corresponding nut 13. The washer 14 keeps the fixed sheave 5 from touching the resistance arm 8 and keeps rotating smoothly. The hinge shaft 7 is provided with two limiting rings 15, and the two limiting rings 15 are clamped on two sides of the power arm 9, so that the tail end of the central shaft is dislocated with the corresponding upright post 4. The purpose of setting up spacing ring 15 is to make the center pin of tight pulley 5 not touch with corresponding stand 4, and both remain dislocation relation throughout, guarantees that the rotation of tight pulley 5 is smooth and easy.

In addition, the material of each lever in this embodiment is manganese steel. The bending strength of the manganese steel is high enough to enable the lever to jack up the base 1 without bending, and the normal service life is long. To cope with a wet construction floor, the outer surface of each roller in this embodiment is provided with an anti-skid rubber layer 16.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
