The stirring rod 6 is driven to rotate by the output end of the motor 401 to achieve the stirring effect. This is the prior art and will not be explained in detail here. The inner wall of the bottom end of the stirring barrel 2 is fixedly connected to a connecting rod 405, and the top of the connecting rod 405 is fixedly connected to a support rod 404. The outer wall of the support rod 404 is fixedly connected to a positioning box 403. The connecting rod 405 can support the support rod 404, and the support rod 404 can support the positioning box 403. The bottom end of the stirring rod 6 is provided with a connecting assembly, which is achieved by rotating the stirring rod 6. The connecting assembly is driven to move, thereby achieving the purpose of automatic dredging. The right end of the connecting assembly is provided with an extrusion plate 402, which is driven to rotate by the movement of the connecting assembly. The center of the connecting rod 405 is fixedly connected to a fixed seat 408. The inner wall of the fixed seat 408 is elastically connected to a movable column 410 through a connecting spring 409. The setting of the movable column 410 and the connecting spring 409 can achieve the purpose of moving up and down, thereby achieving the dredging effect. The top of the movable column 410 is a square surface, and the outer wall of the fixed seat 408 is rotatably connected to a connecting plate 411. The bottom end of the connecting plate 411 is fixedly connected to a breaking plate 412.

An adjusting mechanism 5 is provided at the bottom of the mixing barrel 2, and the overall length of the discharge port can be adjusted through the adjusting mechanism 5, so that the material can be discharged better.

[0035] Reference Figure 2-Figure 4 The outer wall of the worm 407 is rotatably connected to the inner wall of the positioning box 403, and the positioning box 403 can support the worm 407. The inner wall of the positioning box 403 is rotatably connected to the worm gear 406. The center of the worm gear 406 is fixedly connected to the left end of the extrusion plate 402.

The outer wall of the movable column 410 passes through and is slidably connected to the inner wall of the fixed seat 408. The elasticity of the connecting spring 409 enables the movable column 410 to have a reset and extrusion function. The bottom end of the extrusion plate 402 contacts the top end of the movable column 410. When the extrusion plate 402 rotates and the bottom end of the extrusion plate 402 contacts the top square surface of the movable column 410, the movable column 410 moves downward to open the multiple groups of breaking plates 412, and the top outer wall of the connecting plate 411 is rotatably connected to the outer wall of the fixed seat 408. The rotation setting avoids motion interference.

[0037] Reference Figure 1 and Figure 5 The adjusting mechanism 5 includes a telescopic hose 501. The overall length of the telescopic hose 501 can be adjusted and plays a role in discharging. The top of the telescopic hose 501 is fixedly connected to the bottom end of the mixing barrel 2. The two are fixed and can thus support the telescopic hose 501. The bottom end of the telescopic hose 501 is fixedly connected to a guide plate 503. The bottom end of the telescopic hose 501 is the movable end, which is connected to the guide plate 503. The end of the guide plate 503 away from the telescopic hose 501 is slidably connected to the inner wall of the support column 1. The sliding arrangement makes it possible to adjust the overall length of the telescopic hose 501. The inner wall of the guide plate 503 is elastically connected to the latch 5 through the return spring 502. 04, the latch 504 passes through and is slidably connected to the top of the guide plate 503. The penetration setting is convenient for manual movement to release the limit. One end of the return spring 502 is fixedly connected to the outer wall of the latch 504, and the other end of the return spring 502 is fixedly connected to the inner wall of the guide plate 503. The outer wall of the latch 504 is slidably connected to the inner wall of the guide plate 503. The elasticity of the return spring 502 makes the latch 504 have the reset and limit functions. The outer wall of the support column 1 is provided with multiple groups of plug-in holes, and the end of the latch 504 away from the telescopic hose 501 is plugged into the inner wall of the plug-in hole. The two are plugged together to achieve the limiting and fixing effect of the telescopic hose 501, and the setting of multiple groups of plug-in holes is convenient for adjustment.

[0038] Working principle: The top of the mixing barrel 2 is connected to the corresponding air inlet pipe to feed the chemical material. When the material enters the inner wall of the mixing barrel 2, the motor 401 is started, which drives the stirring rod 6 to rotate to achieve the stirring purpose. When the material accumulates on the inner wall of the mixing barrel 2, the stirring rod 6 rotates to drive the worm 407 to rotate, so that the worm gear 406 drives the extrusion plate 402 to rotate. When the extrusion plate 402 rotates downward, it squeezes the top square surface of the movable column 410, causing the movable column 410 to move downward and stretch the connecting spring 409. When the movable column 410 moves downward, it drives multiple groups of connecting plates 411 to open outward, thereby causing the scattering plate 412 to open, so that the accumulated material inside the mixing barrel 2 can be scattered and unblocked to avoid blockage.

[0039] And when it is necessary to collect materials, the collection box can be placed at the bottom end of the telescopic hose 501, and then the latch 504 can be moved to release the plug-in limit between the latch 504 and the support column 1. At this time, the movable end of the telescopic hose 501 can be moved downward, so that the movable end of the telescopic hose 501 contacts the top of the collection box, thereby facilitating material discharge.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
