[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] The utility model provides a plant-mixed hot recycled asphalt mixture mixing equipment. The material is fed from the feed pipe on the side of the feed barrel, and the crushing mechanism is used to crush the large pieces of material fed in, so that the material can be fully mixed. When the crushing mechanism is working, it drives the mixing mechanism to work synchronously to stir and mix the internal materials. Figure 1-Figure 3 , including: a mixing tank 100, a crushing mechanism 200 and a mixing mechanism 300.

[0029] The mixing tank 100 includes a base 110, a tank body 120, a feed barrel 130, a feed pipe 140 and a bracket 150. The tank body 120 is arranged on the base 110. The top side of the tank body 120 is connected to the feed barrel 130. The feed pipe 140 is arranged on the side of the feed barrel 130. The bracket 150 is arranged on the top of the feed barrel 130.

[0030] The tank body 120 adopts an existing mixing barrel with a built-in electric heating wire for heating. The material is fed into the feed barrel 130 through the feed pipe 140 and falls from the feed barrel 130 into the tank body 120 for mixing.

[0031] The crushing mechanism 200 is disposed on the bracket 150. Specifically, the crushing mechanism 200 includes a driving component 210, a driving shaft 220, and a crushing blade 230. The driving component 210 is disposed on the bracket 150 and is connected to the driving shaft 220 extending into the feed barrel 130. The crushing blade 230 is disposed at the lower end of the driving shaft 220.

[0032] The driving component 210 is a rotating motor, which drives the driving shaft 220 to rotate, and the driving shaft 220 drives the crushing blade 230 to rotate.

[0033] The mixing mechanism 300 is disposed on the tank body 120 and connected to the crushing mechanism 200. Specifically, the mixing mechanism 300 includes a mixing shaft 310, a mixing blade 320, a driven wheel 330, a driving wheel 340, and a transmission belt 350. The mixing shaft 310 is rotatably connected to the top center of the tank body 120. The mixing blade 320 is disposed at the lower portion of the mixing shaft 310. The driven wheel 330 is disposed at the top of the mixing shaft 310. The driving wheel 340 is disposed on the driving shaft 220. A transmission belt 350 is connected between the driven wheel 330 and the driving wheel 340.

[0034] Among them, the mixing shaft 310 and the tank body 120 are rotatably connected through a bearing, the mixing blades 320 are set at an angle, and the mixing blades 320 are evenly distributed on the outer wall of the mixing shaft 310. When the driving shaft 220 rotates, it drives the driving wheel 340 to rotate. The driving wheel 340 drives the driven wheel 330 to rotate through the transmission belt 350, and the driven wheel 330 drives the mixing blades 320 to rotate through the mixing shaft 310.

[0035] To facilitate material dropping and prevent dust from entering, the feed pipe 140 is arranged obliquely on the side of the feed barrel 130. An end cover is provided at the outer end of the feed pipe 140. The material can fall along the inclined feed barrel 130 and is sealed by the end cover during operation to prevent dust from entering the feed barrel 130.

[0036] Since the crushing blade 230 rotates at a high speed, the diameter of the driven wheel 330 is larger than the diameter of the driving wheel 340 to reduce the rotation speed of the mixing shaft 310 .

[0037] During specific use, the material is put into the feed barrel 130 through the feed pipe 140, and falls into the tank body 120 from the feed barrel 130 for mixing. The drive shaft 220 is driven to rotate by the driving component 210, and the drive shaft 220 drives the crushing blade 230 to rotate. The crushing blade 230 is used to crush the large pieces of material that fall in. The drive shaft 220 rotates and drives the drive wheel 340 to rotate at the same time. The drive wheel 340 drives the driven wheel 330 to rotate through the transmission belt 350. The driven wheel 330 drives the mixing blade 320 to rotate through the mixing shaft 310 to mix the internal material.

[0038] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
