[0029] See also Figure 1-5, a raw material mixing device, comprising a mixing tank 1, wherein three rotating drums 2 are rotatably provided on the mixing tank 1, each of the rotating drums 2 is connected with a lead screw 3 through an internal thread, and the lower ends of the three lead screws 3 pass through the rotating drum 2 and are fixedly connected with a scraper ring 4, a first motor 5 is fixedly provided on one side of the mixing tank 1, a rotating gear 6 is fixedly connected to the driving end of the first motor 5, and the rotating gear 6 is meshedly connected with a first gear ring 7, the first gear ring 7 is fixedly connected with a rotating ring 8 rotatably connected to the mixing tank 1, a second gear ring 9 is fixedly provided on the inner side of the rotating ring 8, and a toothed belt 10 is fixedly provided on the outer side of each rotating drum 2, and the toothed belt 10 is meshedly connected with the second gear ring 9;
[0030] A support ring 11 is fixedly disposed on the outer side of the mixing tank 1 , and three screw rods 12 are fixedly disposed on the lower end of the support ring 11 . Each of the screw rods 12 is movably connected to a sleeve 13 .
[0031] In this embodiment, when it is necessary to discharge the mixed concrete in the mixing tank 1, a discharge pipe is provided at the lower end of the mixing tank 1. When the discharge pipe is opened, the concrete starts to be discharged, and the first motor 5 is started at the same time. The first motor 5 drives the rotating gear 6 to rotate, and the rotating gear 6 drives the first gear ring 7 to rotate. The first gear ring 7 drives the rotating ring 8 to rotate around the rotating connection with the mixing tank 1, and the rotating ring 8 drives the second gear ring 9 to rotate. Since the second gear ring 9 is meshed with the three toothed belts 10, the rotation of the second gear ring 9 will drive the three toothed belts 10 to rotate at the same time, and the toothed belt 10 drives the rotating drum 2 to rotate. Since the rotating drum 2 is threadedly connected with the lead screw 3, the rotating drum 2 rotates while the lead screw 3 moves downward, and the lead screw 3 drives the scraper ring 4 to move downward. The outer side of the scraper ring 4 contacts the inner wall of the mixing tank 1, thereby scraping the concrete adhering to the inner wall of the mixing tank 1 and discharging it together.
[0032] More specifically, when it is necessary to discharge the concrete, the first motor 5 is started so that the scraper scrapes the concrete adhering to the inner wall of the mixing tank 1 and discharges the concrete together. When placing the entire mixing device, the distance of the screw 12 exposed in the sleeve 13 can be adjusted according to the flatness of the ground, so that the entire mixing device can be placed vertically and stably on the ground.
[0033] See also Figure 1-5 As an implementation method for moving the screw 12: a support seat 14 is fixedly provided at the lower end of the sleeve 13, a drive ring 15 is rotatably provided on each sleeve 13, and the drive ring 15 is threadedly connected to the screw 12. The lower end of the screw 12 extends into the sleeve 13 and is fixedly connected to two limit blocks 16. The sleeve 13 is provided with two limit grooves 17 that cooperate with the limit blocks 16.
[0034] Specifically, the drive ring 15 is rotated. Since the drive ring 15 is threadedly connected to the screw 12, the drive ring 15 drives the screw 12 to move upward while rotating. The screw 12 drives the limit block 16 to move along the limit groove 17 while moving, thereby limiting the screw 12. When the drive ring 15 is rotated in the opposite direction, the screw 12 moves downward, thereby adjusting the length of the screw 12 moved out of the sleeve 13.
[0035] See also Figure 1-5 As an implementation method for mixing concrete raw materials: a driving chamber 18 is provided in the mixing tank 1, and two rotating rods 19 are rotatably provided in the driving chamber 18, and a driving gear 20 is fixedly provided on each of the rotating rods 19, and the two driving gears 20 are meshed and connected, and the lower end of each rotating rod 19 extends into the mixing tank 1 and is fixedly connected to a plurality of stirring rods 21, and a second motor 22 is fixedly provided at the upper end of the mixing tank 1, and the driving end of the second motor 22 extends into the driving chamber 18 and is fixedly connected to one of the rotating rods 19.
[0036] Specifically, a feed hopper is provided at the upper end of the mixing tank 1, and the raw materials required for making concrete are placed into the mixing tank 1 from the feed hopper, and the second motor 22 is started. The second motor 22 drives one of the rotating rods 19 to rotate, and the rotating rod 19 drives one of the driving gears 20 to rotate. Since the two driving gears 20 are meshed and connected, the two driving gears 20 rotate in opposite directions, and the two driving gears 20 drive the two rotating rods 19 to rotate in opposite directions, so that the stirring rods 21 on the two rotating rods 19 rotate in opposite directions, thereby uniformly stirring the concrete raw materials.
[0037] To sum up, when the overall equipment is in use:
[0038] When the entire mixing device needs to be stably placed on the ground, the entire device is placed at the position where it needs to be used. At this time, the support seat 14 is in contact with the ground. When the ground is uneven and the entire device tilts, the drive ring 15 is rotated. Since the drive ring 15 is threadedly connected to the screw 12, the drive ring 15 will drive the screw 12 to move upward while rotating. The movement of the screw 12 will also drive the limit block 16 to move along the limit groove 17 to limit the screw 12. When the drive ring 15 is rotated in the opposite direction, the screw 12 moves downward, thereby adjusting the length of the screw 12 moved out of the sleeve 13, so that the entire mixing device can be placed vertically and stably on the ground.
[0039] When the concrete raw materials need to be stirred, a feed hopper is provided at the upper end of the mixing tank 1, and the raw materials required for making concrete are placed into the mixing tank 1 from the feed hopper, and the second motor 22 is started. The second motor 22 drives one of the rotating rods 19 to rotate, and the rotating rod 19 drives one of the driving gears 20 to rotate. Since the two driving gears 20 are meshed and connected, the two driving gears 20 rotate in opposite directions, and the two driving gears 20 drive the two rotating rods 19 to rotate in opposite directions, so that the stirring rods 21 on the two rotating rods 19 rotate in opposite directions, thereby uniformly stirring the concrete raw materials.
[0040] When it is necessary to discharge the mixed concrete, a discharge pipe is provided at the lower end of the mixing tank 1. The concrete starts to be discharged after the discharge pipe is opened. At the same time, the first motor 5 is started. The first motor 5 drives the rotating gear 6 to rotate, and the rotating gear 6 drives the first gear ring 7 to rotate. The first gear ring 7 drives the rotating ring 8 to rotate around the rotating connection with the mixing tank 1. The rotating ring 8 drives the second gear ring 9 to rotate. Since the second gear ring 9 is meshed with the three toothed belts 10, the rotation of the second gear ring 9 will drive the three toothed belts 10 to rotate at the same time. The toothed belt 10 drives the rotating drum 2 to rotate. Since the rotating drum 2 is threadedly connected with the lead screw 3, the rotating drum 2 rotates while the lead screw 3 moves downward. The lead screw 3 drives the scraper ring 4 to move downward. The outer side of the scraper ring 4 contacts the inner wall of the mixing tank 1, thereby scraping the concrete adhering to the inner wall of the mixing tank 1 and discharging it together.
[0041] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
