[0041] A main drive 111 is fixed on the side of the first support plate 11 away from the second support plate 12, and in the present embodiment, the main drive 111 is a motor, and the output shaft of the main drive 111 is fixedly connected with the rotating shaft 3.

[0042] A telescopic rod 121 is fixed on the side of the second support plate 12 away from the first support plate 11, and the output rod of the telescopic rod 121 is rotatably connected with the moving shaft 4.

[0043] An inlet pipe 21 is fixedly installed on the upper side of one end of each mixing barrel 2 close to the first support plate 11, and an outlet pipe 22 is fixedly installed on the lower side of one end of each mixing barrel 2 close to the second support plate 12, and a valve 23 is installed on the upper end of the outlet pipe 22.

[0044] The rotating cylinder 32 is uniformly fixed with a plurality of fixed baffles 33 between the end close to the first support plate 11 and the rotating shaft 3, and the outer wall of the rotating cylinder 32 is fixed with a rotating wheel 34, and the rotating wheel 34 is circumferentially distributed with a plurality of teeth 35, and the base 1 is fixed with a plurality of auxiliary drives 13 corresponding to the positions of the rotating wheel 34, and in the embodiment, the auxiliary drive 13 is a motor, and the output shaft of the auxiliary drive 13 is fixed with an auxiliary gear 14, and the teeth 35 are engaged with the auxiliary gear 14.

[0045] The inner side of the rotating cylinder 32 is rotatably connected with an inner ring 6, and the rotating shaft 3 is rotatably sleeved with an outer ring 61, and the inner ring 6 is uniformly fixed with a plurality of movable baffles 62 between the end close to the first support plate 11 and the outer ring 61, and the gap between the fixed baffles 33 is adapted to the movable baffles 62, and the fixed baffles 33 are attached to the movable baffles 62.

[0046] One side of the rotating wheel 34 is provided with an exposed groove 36, and both ends of the exposed groove 36 are provided with positioning holes 37. The outer wall of the inner ring 6 is fixed with a positioning block 63, the positioning block 63 is located in the exposed groove 36, a limiting hole 64 is arranged on the positioning block 63, a bolt 65 is arranged in the limiting hole 64, and one end of the bolt 65 is threadedly connected with a nut 66 after penetrating through the limiting hole 64 and one positioning hole 37.

[0047] One side of the fixed baffle 33 and the movable baffle 62 is respectively fixed with an inclined first guide plate 331 and a second guide plate 621. The positions of the fixed baffle 33 and the movable baffle 62 overlap the position of the discharge pipe 22 close to the second support plate 12.

[0048] The material can be poured into the mixing cylinder 2 through the feeding pipe 21. When the valve 23 is opened, the material can be discharged from the mixing cylinder 2 through the discharge pipe 22.

[0049] The main drive 111 is used to drive the rotating shaft 3 to rotate, and the rotating shaft 3 rotates to drive the plow to stir the material in the mixing cylinder 2.

[0050] The telescopic rod 121 is used to drive the moving shaft 4 to move in the rotating shaft 3 through the telescopic function of the telescopic rod 121, and the moving shaft 4 moves to drive the plow 5 to rotate around the support shaft 51 through the engagement between the rack 42 and the rotating gear 52.

[0051] When the telescopic rod 121 grows, the side close to the first support plate 11 of the plow 5 is vertical, and the side close to the second support plate 12 of the plow 5 is inclined, so that the plow 5 pushes the material to the side of the second support plate 12, which is suitable for the case that the material needs to be mixed while being transported.

[0052] When the telescopic rod 121 is shortened, the two sides of the plough 5 are inclined, so that the plough 5 pushes the material to the two sides, which is suitable for the case that the material needs to be mixed in the mixing cylinder 2 for a long time. When the mixing is completed and the valve 23 is opened, the telescopic rod 121 is grown, and at this time the plough 5 pushes the mixed material to the discharge pipe 22, avoiding material residue and facilitating the discharge of the material.

[0053] Since the rotating wheel 34 is rotationally connected between the mixing cylinders 2, the mixing cylinders 2 can be assisted to support the rotating shaft 3 through the rotating wheel 34 and the fixed baffle 33. The auxiliary driver 13 drives the rotating wheel 34 to rotate through the auxiliary gear 14 and the teeth 35, thereby assisting the rotating shaft 3 to rotate.

[0054] After the bolt 65 and the nut 66 are removed, the positioning block 63 can move in the exposed groove 36, thereby driving the inner ring 6, the outer ring 61 and the movable baffle 62 to rotate relative to the rotating wheel 34. The bolt 65 and the nut 66 are used to fix the positioning block 63 at one end of the exposed groove 36.

[0055] When the positioning block 63 is fixed at one end of the exposed groove 36, the fixed baffle 33 and the movable baffle 62 are positionally coincident, so that the material can flow between the mixing cylinders 2 on both sides of the inner ring 6 through the gap between the fixed baffles 33.

[0056] When the positioning block 63 is fixed at the other end of the exposed groove 36, the movable baffle 62 blocks the gap between the fixed baffles 33, thereby separating the mixing cylinders 2 on both sides of the inner ring 6.

[0057] When the fixed baffle 33 and the movable baffle 62 are positionally coincident, the rotation of the rotating shaft 3 drives the first guide plate 331 and the second guide plate 621 to rotate, thereby avoiding the material from staying at the inner ring 6.

[0058] When the movable baffle 62 blocks the gap between the fixed baffles 33, since the fixed baffle 33 and the movable baffle 62 are positionally overlapped with the side of the discharge pipe 22 close to the second support plate 12, the material clamped by the first guide plate 331, the fixed baffle 33 and the movable baffle 62 is thrown into the discharge pipe 22, thereby avoiding material residue.

[0059] In summary, through the movable baffle 62, the adjacent two mixing cylinders 2 can be connected or separated, thereby controlling the volume and length of the mixing chamber when the material is mixed.

[0060] When the material needs to be mixed in the mixing cylinder 2 for a long time, by controlling the volume of the mixing chamber, the height of the material in the mixing chamber can be controlled, avoiding that the material is too low to cause low mixing efficiency or the material is too high to overflow.

[0061] When the material is mixed while being transported, the length of the mixing chamber can be controlled to control the mixing time of the material, ensuring sufficient mixing.

[0062] By adjusting the angle of the plough 5 and controlling the communication or separation between the mixing cylinders 2, the plough mixer is divided into multiple mixing chambers, and the mixing method of each mixing chamber can be adjusted according to the material. The plough mixer can simultaneously mix multiple different materials, and the mixing method of each material is adjusted separately.
