DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] A portable concrete mixer, see Figure 1-Figure 5 As shown, it includes a wheel 1, a handle 102, a sleeve 2, a mounting frame 3, an elastic member 4, a mounting shell 5, a first motor 6, a rotating paddle 7, a belt 8, a stirring rod 9 and a first protective shell 10. The mounting frame 3 is slidably arranged on the four sleeves 2, and the elastic member 4 is connected between the mounting frame 3 and the four sleeves 2. The wheel 1 is rotatably arranged on the lower part of the sleeve 2, wherein a handle 102 is fixedly connected between two sleeves 2, and the handle 102 is located on the left side of the mounting frame 3. The mounting shell 5 is slidably arranged on the front and rear parts of the mounting frame 3. The first motor 6 is arranged on the left part of the front mounting shell 5 by bolt connection, and the rotating paddle 7 is fixedly connected to the output shaft of the first motor 6. The stirring rod 9 is rotatably arranged between the right parts of the two mounting shells 5, and a belt 8 is wound between the stirring rod 9 and the output shaft of the motor. The first protective shell 10 is arranged between the upper parts of the two mounting shells 5 by welding.

[0024] See also Figure 1 and Figure 3 As shown, a rubber sleeve 18 is also included. The rubber sleeve 18 is sleeved on the handle 102. The rubber sleeve 18 increases the friction between the staff's hand and the handle 102, so that the staff can better hold the handle 102.

[0025] See also Figure 1 and Figure 2As shown, an anti-skid cover 19 is also included. The wheel 1 is covered with the anti-skid cover 19, and the anti-skid cover 19 increases the friction between the wheel 1 and the ground, thereby preventing the wheel 1 from slipping.

[0026] When the device is to be used, the staff will hold the push handle through the rubber sleeve 18, and then push the push handle to make the wheel 1 rotate and drive the device to move to the specified position, so that it is convenient for the staff to move the device, thereby achieving the purpose of facilitating the staff to carry. During transportation, the mounting frame 3 moves up and down to squeeze the elastic member 4 to deform, so that the elastic member 4 buffers the mounting frame 3. When the first protective shell 10 moves above the concrete raw material, the staff starts the first motor 6. The output shaft of the first motor 6 drives the rotating paddle 7 and the belt 8 to rotate. The rotation of the belt 8 drives the stirring rod 9 to rotate, thereby mixing the concrete raw materials. After mixing is completed, the staff can turn off the first motor 6. Example 2

[0027] Based on Example 1, see Figure 4 As shown, it also includes a second motor 11, a threaded rod 12 and a first guide rod 13. The second motor 11 is provided on the left rear portion of the mounting frame 3 by bolt connection. The output shaft of the second motor 11 is fixedly connected to the threaded rod 12 through a coupling. The first guide rod 13 is fixedly connected to the front inner portion of the mounting frame 3. The front mounting shell 5 slides on the first guide rod 13, and the rear mounting shell 5 is threadedly connected to the threaded rod 12.

[0028] See also Figure 1 and Figure 4 As shown, a second protective shell 17 is also included. The second protective shell 17 is fixedly connected to the left side of the rear side of the mounting frame 3. The second protective shell 17 is used to protect the second motor 11.

[0029] When mixing the concrete raw materials, the staff starts the second motor 11, and the output shaft of the second motor 11 rotates to drive the threaded rod 12 to rotate and drive one of the mounting shells 5 to move to the right. The movement of one of the mounting shells 5 to the right drives the first protective shell 10 to move to the right. The movement of the first protective shell 10 to the right drives the other mounting shell 5 to move to the right, so that the rotating paddle 7 and the stirring rod 9 move to the right, and then the concrete raw materials can be fully stirred, so that the concrete raw materials are mixed more evenly. After mixing to an appropriate degree, the staff can turn off the first motor 6 and the second motor 11.

[0030] See also Figure 5 As shown, it also includes a second guide rod 14, a scraper 15 and a handle 16. The second guide rods 14 are fixedly connected to the left and right parts of the first protective shell 10. The scraper 15 is slidably arranged between the two second guide rods 14. The handle 16 is fixedly connected to the left side of the top of the scraper 15, and the handle 16 slides on the first protective shell 10.

[0031] When the mixing of the concrete raw materials is completed, the staff holds the handle 16 and moves backward. The movement of the handle 16 drives the scraper 15 to move backward, so that the concrete adhering to the first protective shell 10 can be scraped off, making it easier for the staff to clean up. After the cleaning is completed, the staff can release the handle 16.

[0032] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
