[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] This invention discloses a portable, small-scale soil mixer for experimental use, such as... Figure 1-2 As shown, the device includes a handle-type main unit and a stirring head, the stirring head being fixedly connected to a stirring shaft 3; the main unit includes a housing 8, inside which a motor 6 is installed, one end of the output shaft 13 of the motor 6 being connected to the stirring shaft 3, and one end of the stirring shaft 3 passing through the horizontal section of the main unit and being fixedly connected to the output shaft 13 of the motor; an LCD display is also connected to the upper part of the main unit; the LCD display is electrically connected to the motor 6; and a stirring table 25 corresponding to the stirring head is also included, the stirring table 25 being used to prevent material splashing during the stirring process.

[0021] The stirring head includes a stirring ring 2, along which are a number of downward-facing stirring claws 1 and flexible, soft-blade-shaped stirring teeth 28 made of hard plastic. There are three stirring teeth 28, all distributed on the stirring ring 2. Each stirring claw 1 is provided with a stirring blade 10, which surrounds the stirring claw 1. The front end of the stirring claw 1 is serrated.

[0022] The LCD display includes a timing module 27 for timing display during the stirring process and a speed display module 20 for real-time display of stirring speed. The speed display module 20 is equipped with an increase stirring shaft speed button 21 and a decrease stirring shaft speed button 22. The timing module 27 includes a time setting button 18 for adjusting the time setting level. The increase stirring shaft speed button 21, decrease stirring shaft speed button 22 and time setting button 18 are respectively connected to a controller connected to the motor 6.

[0023] The host is equipped with a switch 15, which is connected to the motor 6 via a cable.

[0024] The mixing platform 25 is provided with an elliptical mixing tank 24, which is installed in the mixing platform 25 by a mixing tank fixing bracket 23; the shape of the mixing tank 24 is adapted to the mixing blades on the mixing claws and the rhomboid structure at the front end of the claws.

[0025] The switch is located on the front side of the handle.

[0026] The motor 6 is fixed by a motor bracket 14 inside the housing; the motor 6 is connected to a power plug 16 via a main power cord 17; the stirring shaft 3 is movably fixed inside the housing by a stirring shaft retainer 12, and the stirring shaft 3 is connected to the output shaft 13 via an output transmission gear set 4.

[0027] The liquid crystal display is connected to the motor 6 via the display cable 26.

[0028] The stirring shaft reinforcement structure 11 is made of stainless steel and is fitted into the middle of the stirring shaft.

[0029] Working principle of the invention:

[0030] This invention discloses a portable experimental small soil mixer, in which the main unit, output shaft, and motor are fixedly connected together. Internally, a switch and an LCD display work together to power the motor. The output shaft is connected to a stirring shaft at its front end. The motor outputs power to drive the output shaft to rotate, which in turn drives the stirring shaft to rotate, causing the stirring claws to move in a circular and vertical motion. The main unit can be used as a handle to manually move and adjust the direction and angle of the stirring head for better mixing of materials in the mixing tank. The stirring head is equipped with paddles for efficient mixing of soil materials and prismatic stirring teeth to facilitate thorough mixing of the soil materials.

[0031] The main unit is equipped with an LCD control device on top, which allows for different time settings and different speed combinations, making it easier, faster and more efficient for operators to set the stirring mode that meets their own needs.

[0032] The mixer comes with a mixing platform containing an elliptical mixing drum. The handheld unit can thoroughly and evenly mix the soil material in the elliptical mixing drum at various angles. Since the mixing drum is fixed inside the mixing platform, which is itself a container, any material that splashes out of the mixing drum can be collected, making the experimental data measurement more accurate.

[0033] The liquid crystal display screen of this invention is connected to the motor on the bracket inside the main unit housing via a cable. The display screen has a timing function and can display the output shaft speed level (the speed level is displayed on the second screen below the display screen). The liquid crystal display screen includes two liquid crystal display screens. There is a button below the upper screen for adjusting the time setting level. There are five levels to choose from, which is convenient for short-term mixing timing in different scenarios of soil material mixing. It can easily time different times such as 1 minute, 3 minutes, 5 minutes, 10 minutes, and 15 minutes. The display screen for different speed levels of the mixing shaft is located below the timing display screen and can display the speed output of the mixing shaft. There are three buttons below the speed display screen. The left button is the save setting button, which can save the current setting when pressed. The two buttons on the right are the increase and decrease buttons for the mixing shaft speed, which can increase or decrease by 50 rpm each time. The mixing shaft speed range is from 50 to 2000 rpm. The timing function, combined with the different speed levels of the mixing shaft, can make the mixing effect more ideal.

[0034] This portable experimental soil mixer is equipped with a mixing platform for better and more thorough mixing of soil materials. Common mixers use fixed mixing teeth on a mixing shaft, which can only achieve parallel mixing and cannot evenly mix the soil materials at the top and bottom, thus affecting the accuracy of subsequent soil physicochemical property testing. This mixer, however, comes with a mixing platform with an internal elliptical spherical mixing tank. With the mixing blades on the mixing claws and the diamond-shaped structure design at the front of the claws, the handheld unit can thoroughly and evenly mix the soil materials in the elliptical spherical mixing tank at various angles, providing better and more accurate samples for subsequent soil physicochemical property testing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
