Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

As can be seen from Figures 1 to 4, an asphalt mixture mixer includes a horizontal stirring tank 1, a feeding port 2 is provided above the stirring tank 1, a discharging port 3 is provided on the lower side of the stirring tank 1, and a stirring rod 4 is provided. The stirring rod 4 is detachable inside. The stirring rod 4 is S-shaped. One end of the stirring rod 4 is provided with a fixed shaft 5. The stirring tank 1 is telescopically provided with a fixed sleeve 6 sleeved with the fixed shaft 5. The other end of the stirring rod 4 is provided with The connecting plate 7, the mixing tank 1 is rotatably provided with a shaft sleeve 8 that cooperates with the connecting plate 7, the shaft sleeve 8 is provided with a main shaft 9 connected to the motor 20, and the main shaft 9 is slidably provided with a driving ring gear 10, and the connecting plate 7 There is a driven ring gear 11 matched with the driving ring gear 10 , and the driving ring gear 10 and the driven ring gear 11 are meshed to form a structure in which the motor 20 drives the stirring rod 4 to rotate.

When the utility model is specifically used,

Put the asphalt mixture into the mixing tank 1 from the feeding port 2, start the motor 20, and drive the stirring rod 4 to rotate, so that the asphalt mixture is mixed and finally discharged from the discharge port 3.

After the work is completed, the stirring rod 4 is taken out from the mixing tank 1, and the stirring rod 4 is cleaned outside, and it is very easy to clean without the stirring rod 4 in the mixing tank 1, and the remaining asphalt can be mixed without leaving a dead angle. The material is cleaned up so that it will not be mixed with the asphalt mixture in the next use to ensure the purity of the asphalt.

The two ends of the stirring rod 4 are respectively sleeved with the fixed sleeve 6 and the shaft sleeve 8 , which are not fixedly connected, and are easy to be taken out from the stirring tank 1 .

The bottom of the mixing tank 1 is provided with a plurality of supporting legs 12 to ensure the stability of the mixing tank 1 .

One end of the mixing tank 1 is provided with a fixing box 13 located outside the fixing sleeve 6, and the fixing sleeve 6 is provided with an adjusting rod 14 threadedly connected with the fixing case 13. Rotating the adjusting rod 14 makes the length of the fixing sleeve 6 in the mixing tank 1 change, Thus, the stirring rod 4 is fixed inside the stirring tank 1 .

The shaft sleeve 8 is connected with the stirring tank 1 in a sliding and sealing manner. The outer end of the shaft sleeve 8 is provided with a baffle plate 15. The main shaft 9 is sleeved with a first spring 16 located between the baffle plate 15 and the driving gear ring 10. The limit plug 17, the main shaft 9 is connected with the driving ring gear 10 by key, the outside of the stirring tank 1 is fixed with a drive box 18, the motor 20 is fixed in the drive box 18, and the main shaft 9 is sleeved with a space between the drive box 18 and the baffle 15. the second spring 19 in between.

The existence of the baffle plate 15 enables the second spring 19 to be limited when the shaft sleeve 8 is pushed to move, and will not completely enter the inside of the mixing tank 1. The limiting plug 17 can restrict the driving ring gear 10 from leaving the main shaft 9, and can always be connected with the main shaft 9. The main shaft 9 maintains the key connection so as to rotate synchronously with the main shaft 9 .

When installing the stirring rod 4, move the adjusting rod 14 outward so that the distance between the fixed sleeve 6 and the end of the main shaft 9 is the farthest. At this time, the stirring rod 4 is put into the stirring tank 1 from the feeding port 2, and the fixed shaft 5 is connected to the The fixed sleeve 6 is sleeved, the connecting plate 7 is matched with the shaft sleeve 8, and then the adjusting rod 14 is rotated, so that the fixed sleeve 6 moves in the direction of the main shaft 9, so that the stirring rod 4 is fixed, and the connecting plate 7 is in contact with the shaft sleeve 8 to push the shaft sleeve. 8 moves to the outside, compresses the second spring 19, the driven ring gear 11 contacts the driving ring gear 10, and completes the meshing, and the main shaft 9 can drive the stirring rod 4 to rotate in the stirring tank 1. If the stirring rod 4 is overloaded during rotation In this case, an axial thrust is generated between the driving ring gear 10 and the driven ring gear 11, which compresses the first spring 16, so that the driving ring gear 10 is kept away from the driven ring gear 11, so as to realize overload protection and avoid damage to parts due to rigid impact. .

Compared with the prior art, the utility model has the following beneficial effects: the stirring rod can be disassembled, so that the inside of the stirring tank is easy to clean; the installation of the stirring rod is simple and fast, and it is not necessary to use too many screws for fixed connection, and the disassembly and assembly can be completed quickly , shorten the cleaning time; the non-rigid connection between the stirring rod and the main shaft can protect the overload, avoid damage to the motor and transmission components, and prolong the service life of the equipment.
