An output rotating shaft of the turnover motor is connected with a driving shaft 71, the driving shaft 71 is rotatably connected with the discharging shell 5, and the flap 51 is connected to the driving shaft 71.

[0049] The first conveying belt 2 comprises a driving drum 21, a passive drum 22, a belt 23, a transmission shaft 24, a friction wheel 25, a belt motor 26 and a transmission wheel 27. The driving drum 21 and the passive drum 22 are both rotatably connected with the upper end of the vehicle frame 1, and the belt 23 is connected between the driving drum 21 and the passive drum 22. The driving drum 21 is coaxially connected with the transmission shaft 24, and the transmission shaft is connected with the friction wheel 25. The belt motor 26 is arranged on the vehicle frame 1, the output rotating shaft of the belt motor 26 is connected with the transmission wheel 27, and the transmission wheel 27 frictionally contacts the friction wheel 25 on the side surface.

[0050] The transmission wheel 27 is a truncated cone, and the uppermost generatrix is flush with the horizontal plane; the outer surface of the transmission shaft 24 is provided with a spline, and the center position of the friction wheel 25 is provided with a spline hole.

[0053] A batching machine is provided with the sand and stone material mixing mechanism described above in the embodiment.

[0054] The operation process of the sand and stone material mixing mechanism described in the embodiment is as follows:

[0055] The user first puts three or two different materials into different hoppers 4. Taking the mixing of three materials as an example, the user determines the mixing ratio of the three different materials, and then the user controls the batching machine to move to the unloading position, and then the user starts the overturning motor to drive the three drive shafts 71 to rotate at different angles, the drive shafts 71 drive the turning plates 51 to rotate (the ratio of the turning angles of the three turning plates 51 is always the same as the mixing ratio of the three materials), so that the turning plates 51 lose the blocking of the discharge ports of the hoppers 4, and the materials in the hoppers 4 move downward through the downflow shell 5 to the second conveying belts 6, and the user simultaneously starts the three second conveying belts 6, which drive the materials thereon to move to the right until the materials fall downward to the first conveying belt 2, and the three materials overlap and mix on the belt 23 of the first conveying belt 2. At the same time, the user starts the belt motor 26, and the output shaft of the belt motor 26 drives the transmission wheel 27 to rotate, which drives the friction wheel 25 to rotate in a frictional manner, and the friction wheel 25 drives the transmission shaft 24 to rotate, which drives the drive drum 21 of the first conveying belt 2 to rotate. At this time, the belt 23 of the first conveying belt 2 is converted from a static state to a conveying state, and the belt 23 of the first conveying belt 2 drives the materials thereon to move to the right, and at the same time, the three materials are mixed on the belt 23 of the first conveying belt 2.

[0056] When the three drive shafts 71 rotate, taking one of the drive shafts 71 as an example, the drive shaft 71 drives the drive gear 72 thereon to rotate, which engages with the rack 82 and drives the extension rod of the first hydraulic cylinder 81 to move downward until the drive shaft 71 stops rotating, and the extension rod of the first hydraulic cylinder 81 stops moving downward. In this process, the extension rod of the first hydraulic cylinder 81 moves downward and extrudes the hydraulic oil in the first hydraulic cylinder 81 to be transmitted to the second hydraulic cylinder 83 through the hydraulic pipeline, and the hydraulic oil in the second hydraulic cylinder 83 drives the extension rod of the second hydraulic cylinder 83 to move forward, which drives the pusher seat 28 to move forward, and the pusher seat 28 drives the friction wheel 25 to move forward, thereby changing the transmission ratio between the friction wheel 25 and the transmission wheel 27 (i.e., the total amount of the three materials discharged is proportional to the conveying speed of the belt 23 of the first conveying belt 2), and the running speed of the first conveying belt 2 can match the discharging speed of the hopper 4, thereby preventing the materials on the belt 23 of the first conveying belt 2 from being too thick, avoiding the leakage of materials, and reducing the subsequent processing workload.

[0057] So far, the embodiment has been described in detail in combination with the drawings. According to the above description, those skilled in the art should have a clear understanding of the sand and stone material mixing mechanism and the batching machine of the utility model.

[0058] The embodiments of the utility model are only used for describing the technical scheme of the utility model and not for limiting, and for those skilled in the art, it can be understood that the embodiments can be changed, modified, replaced and changed in many ways without departing from the principles and spirits of the utility model, and the range of the utility model is defined by the appended claims and its equivalents.
