Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Specifically, the support base 8 is driven by starting the hydraulic rod 7 to move it upward, and the stirring device 3 is started at the same time, so that the stirring blade 4 starts to rotate, so as to perform stirring and mixing work. During the cleaning process, by moving the support base 8 upward, the distance between it and the annular nozzle 11 can be shortened, and the pressure pump 9 is used to deliver water through the delivery pipe 10, so that the annular nozzle 11 can spray and clean the stirring pot 6 and the stirring blade 4, thereby achieving the effect of automatically cleaning the remaining cement inside the stirring pot 6. The stirring device 3 is started, so that the stirring blade 4 drives the oscillation plate 5 to rotate. When the support base 8 drives the stirring pot 6 to move, the oscillation plate 5 can clean and scrape the inner wall of the stirring pot 6. The oscillation plate 5 vibrates under the obstruction of the barrier column 16, so as to clean the cement adhered to the surface of the oscillation plate 5, thereby avoiding increasing the maintenance cost of the mixer and improving the effect of cleaning the stirring pot 6.

[0041] Reference Figure 1 、 Figure 2 and Figure 5 The stabilizing mechanism 2 includes two connecting plates 201, the top walls of the two connecting plates 201 are fixedly connected to the left and right sides of the bottom wall of the support base 8 respectively, one side of the connecting plate 201 is fixedly connected to an L-shaped plate 202, one side of the L-shaped plate 202 is fixedly connected to a swing cylinder 203, one end of the swing cylinder 203 is fixedly connected to a swing rod 204, and the top end of the swing rod 204 is rotatably connected to a clamping plate 205 through a torsion spring;

[0042] Specifically, the stirring pot 6 is placed at the top position of the support base 8 to ensure its stability and safety, and the swing cylinder 203 is started. The swing rod 204 starts to rotate through the action of air pressure, and then drives the clamping plate 205 to rotate, so that the clamping plate 205 gradually approaches the position of the stirring pot 6. The clamping plate 205 is connected to the swing rod 204 through a torsion spring. When the clamping plate 205 contacts the outer wall of the stirring pot 6, the elasticity of the torsion spring allows the clamping plate 205 to rotate slightly, so that the clamping plate 205 can better fit the outer wall of the stirring pot 6, thereby improving the clamping stability.

[0043] Reference Figure 1 、 Figure 4 and Figure 5 The stabilizing mechanism 2 further includes two rubber pads 206, the two rubber pads 206 having their sides facing away from each other fixedly connected to the adjacent sides of the corresponding plywood 205; a control switch 17 is fixedly connected to the right side of the stirring device 3, and the control switch 17 is electrically connected to the stirring device 3, the pressure pump 9 and the swing cylinder 203 respectively; a locking block 12 is fixedly connected to the bottom end of the stirring pot 6, and a locking groove 13 is provided on the top wall of the support base 8, and the bottom of the locking block 12 is engaged with the locking groove 13;

The control switch 17 is electrically connected to the stirring device 3, the pressure pump 9 and the swing cylinder 203 respectively, so that the control switch 17 can complete the opening and closing of the device. The bottom of the locking block 12 is engaged with the locking groove 13, so that the connection effect between the support base 8 and the stirring pot 6 is improved. The model of the pressure pump 9 used in the utility model is the pressure pump STA25, and the model of the swing cylinder 203 is the swing cylinder QGK.

[0045] Reference Figure 3 、 Figure 4 and Figure 5 , the rear side of the support seat 8 is fixedly connected with a stabilizing plate 14, the front side of the inner wall of the stirring device 3 is provided with a slide groove 15, and the rear side of the stabilizing plate 14 is slidably connected to the slide groove 15; a rubber ring 20 is fixedly installed on the top of the outer wall of the delivery pipe 10, and the outer wall of the rubber ring 20 is fixedly connected to the left side of the annular nozzle 11; the front and rear sides of the inner wall of the fixing plate 1 are fixedly connected to two connecting seats 18, and the top walls of the multiple connecting seats 18 are provided with mounting grooves 19;

[0046] Specifically, the rear side of the stabilizing plate 14 is slidably connected to the slide groove 15, making it more stable when the support seat 8 is displaced. The rubber ring 20 increases the service life of the connection of the delivery pipe 10, thereby improving the wear resistance of the connection of the delivery pipe 10. The connecting seat 18 and the mounting groove 19 facilitate installation and fixation of the device, reducing the risk of falling.

[0047] Working principle: When starting to use, the support seat 8 is driven by starting the hydraulic rod 7, so that the support seat 8 moves upward, the stirring device 3 is started, and the stirring blade 4 rotates, thereby performing stirring work. When cleaning, the support seat 8 moves upward, and the distance between it and the annular nozzle 11 is shortened, so that the pressure pump 9 delivers water through the delivery pipe, so that the annular nozzle 11 can spray and clean the stirring pot 6 and the stirring blade 4, and then the remaining cement inside the stirring pot 6 can be cleaned. At the same time, the stirring device 3 is started, and the stirring blade 4 drives the oscillation plate 5 to rotate, so that when the support seat 8 drives the stirring pot 6 to move, the oscillation plate 5 can clean and scrape the inner wall of the stirring pot 6, so that the oscillation plate 5 is in the barrier column 16. Vibration is performed under the obstruction, so that the cement adhered to the surface of the oscillation plate 5 can be cleaned, thereby avoiding the situation of increasing the maintenance cost of the mixer, and improving the effect of cleaning the mixing pot 6. By placing the mixing pot 6 on the top of the support base 8 and starting the swing cylinder 203, the swing rod 204 drives the clamping plate 205 to rotate, so that the two clamping plates 205 are close to the position of the mixing pot 6. At the same time, the clamping plates 205 connected by the torsion spring can be rotated when they contact the mixing pot 6, so that the clamping plates 205 are more in line with the outer wall of the mixing pot 6, thereby improving the clamping stability of the mixing pot 6, avoiding the situation that shaking during stirring affects the mixing of cement mortar, thereby improving the stability during stirring and increasing the accuracy of the experiment.
