Description

A hand-held electric telescopic soil stirrer

technical field

The utility model relates to a soil stirrer, which is mainly a hand-held electric telescopic soil stirrer and belongs to the technical field of civil engineering experiments.

technical background

In the soil engineering test, it is necessary to stir the soil sample evenly, so as to measure some of its physical and mechanical indexes. At present, the following methods are mainly used: (1) Use the soil mixing knife to mix the soil samples to make them uniform. Disadvantages: Because the soil mixing knife is controlled by humans, human factors will have a certain impact on the process of mixing soil samples, such as Improper control of human mixing strength, dead angles in mixing, laborious manual work, etc., will reduce the uniformity of mixing of soil samples. In addition, the current soil-conditioning knife is relatively small, mostly 180mmx80mm, which is suitable for relatively small soil sample containers, which limits the scope of application of the soil-conditioning knife; (2) Large-scale soil-mixing devices, due to their complex structure, are inconvenient to move , and the cost of use is relatively large, so it also limits its role to a certain extent.

Contents of the invention

The purpose of the utility model is to provide a hand-held electric telescopic soil stirrer.

The problem to be solved by the utility model is: in the geotechnical experiment, the existing soil stirring device is inconvenient in operation and use, has a small adaptable range and a complicated structure.

For realizing the purpose of the utility model, the technical scheme that this use model adopts is:

A hand-held electric telescopic soil agitator, comprising a hand-held housing, connecting wires, a motor and a switch, the motor is arranged inside the hand-held housing, the switch is installed under the hand-held housing, and a wire is connected between the motor and the switch; the motor is also connected to a useful For the connecting wire for power supply, a coupling is provided at the top of the motor, and the coupling is connected with a rotating rod, and a sliding sleeve with the same length is set on the rotating rod; screw holes 1 are evenly distributed on the rotating rod, and the sliding sleeve There is a screw hole 2 corresponding to the screw hole 1 on the top, and the sliding sleeve and the rotating rod are screwed into the screw hole 1 and the screw hole 2 with fastening screws for internal fixation; the bottom of the sliding sleeve is provided with a U-shaped stirring rod .

The U-shaped stirring rod is also provided with a slanted plate.

The sliding sleeve and the rotating rod are made of brass.

A baffle plate is also provided under the handheld housing.

The utility model has the advantage that, by adopting a hand-held electric method to stir the soil sample, not only the stirring speed is fast but also the stirring is uniform. At the same time, the length between the rotating rod used for stirring and the sliding sleeve can be adjusted to be suitable for soil sample containers of different depths. It solves the problems of inconvenient operation, small adaptable range and complex structure of the original soil stirring device. Therefore, the utility model has the advantages of simple structure and saving experiment time, and has broad market prospects.

specific implementation plan

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figures 1 and 2, a hand-held electric telescopic soil mixer includes a hand-held housing 1, a connecting wire 3, a motor 4 and a switch 12, the motor 4 is arranged inside the hand-held housing 1, and the switch 12 is installed in the hand-held housing 1 Below, the hand-held housing 1 is also provided with a baffle plate 7 which is used to cover the soil holding cylinder during use, and a lead 2 is connected between the motor 4 and the switch 12 so that the switch 12 controls the motor 4 to start and close; the motor 4 also The connecting wire 3 for power supply is connected, the connecting wire 3 is connected to an external power supply, the top of the motor 4 is provided with a coupling 5, the coupling 5 is connected with a rotating rod 8, and the rotating rod 8 is covered with a sliding sleeve of the same length. 9. Both the sliding sleeve 9 and the rotating rod 8 are made of brass; the rotating rod 8 is evenly provided with screw holes 15, and the sliding sleeve 9 is provided with screw holes 2 11 corresponding to the screw holes 15, The sliding sleeve 9 and the rotating rod 8 are screwed into the first screw hole 15 and the second screw hole 11 by the fastening screw 10. The first screw hole 15 and the second screw hole 11 have the same number and correspond to each other. The fastening screw 10 can be moved and disassembled. , screw hole one 15 and screw hole two 11 can be installed with fastening screws 10, and can also be partially installed; the sliding sleeve 9 is provided with a U-shaped stirring rod 13, and the U-shaped stirring rod 13 is also provided with a slanted piece 14 To enhance stirring ability.

Please refer to Fig. 3 emphatically, the working principle of the present utility model is such that the sliding sleeve 9 is adjusted to expand and contract on the rotating rod 8 according to the depth of the soil sample container, making it stretch or shorten to adapt to the depth of the soil sample container, and the adjustment is completed Use fastening screw 10 to fix afterwards, the user puts the utility model on the soil sample container, covers the soil sample container by baffle plate 7, connects the connecting wire 3 to an external power supply to energize the motor 4, and holds it tightly by hand. The shell 1 controls the start and stop of the motor 4 through the switch 12. The rotation of the motor 4 drives the rotating rod 8 to rotate through the coupling 5 so that the U-shaped stirring rod 13 rotates to stir the soil sample in the soil sample container, making it uniform and stirring. After the completion, take out the whole soil agitator by holding the hand-held housing 1 tightly, and the soil sample in the soil sample container can be used. The utility model is easy to operate and has high work efficiency, and can adapt to the stirring operation of soil sample containers of different depths.
