Please refer to Figures 1-4. In order to facilitate the accurate weighing and delivery of various raw materials for concrete to the inside of the mixing box 4, the adjustment mechanism 2 in this embodiment includes a mounting plate 201 fixed on the fixing frame 1, a driving component provided on the mounting plate 201 and the mixing box 4, an adjusting component provided on the driving component and used for adjustment, and a gravity sensing plate 210 provided on the adjusting component for sensing weight. After the various raw materials for making concrete are weighed according to the required ratio, the various raw materials with determined weights are put into the mixing box 4 for mixing and mixing to ensure the quality of the concrete.

Among them, the driving component includes two adjusting rods 202 rotatably connected to the inner wall of the mounting plate 201, an adjusting motor 206 fixed to one side of the mounting plate 201, a first transmission wheel 203 fixed to the outer surface of the front adjusting rod 202, a second transmission wheel 204 fixed to the outer surface of the back adjusting rod 202, and a conveyor belt 205 connected between the first transmission wheel 203 and the second transmission wheel 204, which provide a power source for the stable movement of the two sets of adjusting rods 202, so that the two sets of L-shaped adjusting rods 208 can be more stable when driving the two connecting support plates 209 and the gravity sensing plate 210 to move.

At the same time, the adjustment component includes an eccentric turntable 207 fixed on the opposite side of the adjustment rod 202, an L-shaped adjustment rod 208 rotatably connected to the side of the eccentric turntable 207 away from the center of the circle through a bearing, and a connecting support plate 209 hinged on the top of the L-shaped adjustment rod 208.

In addition, the opposite ends of the two front adjustment rods 202 are respectively fixed to the output shafts of the two adjustment motors 206, and the opposite ends of the two rear adjustment rods 202 are respectively rotatably connected to the inner walls of the two mounting plates 201, which can make the rotation of the two sets of adjustment rods 202 themselves more stable, and thus more conducive to driving the eccentric turntable 207 to rotate, and then driving the L-shaped adjustment rod 208 to move.

When in use, the required concrete preparation raw materials are put into the weighing box 3, and then the gravity sensing plate 210 can be used for sensing. When the weight of the required concrete preparation raw materials reaches the set value, the corresponding adjusting motor 206 will be turned on, which can drive the front adjusting rod 202 and the first transmission wheel 203 to rotate. The first transmission wheel 203 drives the second transmission wheel 204 to rotate through the conveyor belt 205, so that the back adjusting rod 202 can be rotated. At this time, both adjusting rods 202 can rotate, which can cause the eccentric turntable 207 to rotate. Then, the rotation of the eccentric turntable 207 can drive the L-shaped adjusting rod 208, so that the connecting support plate 209 hinged to the L-shaped adjusting rod 208 also moves. Because one end of the connecting support plate 209 It is hinged with the inner wall of the weighing box 3, so the connecting support plate 209 can drive the gravity sensing plate 210 fixed thereto, and the two can adjust their angles with the point where they are hinged with the weighing box 3 as the base point until they are adjusted to the maximum angle, and the raw materials with a good weight ratio in the weighing box 3 can enter the mixing box 4 through the feed port.
