Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent mixing equipment, in particular to a multi-directional premixer for microbial agent raw materials. Background Art

[0003] The prior art uses a motor to drive the barrel to swing to achieve mutual extrusion of materials to promote premixing. Centrifugal force is generated during the barrel swinging process, causing the mounting frame to be subjected to a large force. As time goes by, the mounting frame is prone to displacement and loosening. If two barrels are symmetrically arranged and the two barrels are swung in opposite directions, the eccentric forces generated by the two barrels can suppress and offset each other, thereby alleviating the displacement and loosening of the mounting frame.

Two connecting shafts 12 are symmetrically arranged on the wall of each mixing barrel 11, one of which is rotatably connected to the inner wall of the base 10, and the two connecting shafts 12 close to each other are transmitted to each other through the driving assembly. A support plate is fixedly connected to the center position of the top surface of the base 10, and the shell 20 forms a hollow box structure and is fixedly installed on the top of the support plate. The shell 20 has a cavity, and the two connecting shafts 12 close to each other both extend into the cavity of the shell 20. In this scheme, two mixing barrels 11 are arranged on the top surface of the base 10, and the two mixing barrels 11 are pushed and kept to swing in the opposite direction by the driving assembly, so that the eccentric forces generated when the two mixing barrels 11 swing offset each other, which can suppress the deviation of the base 10 caused by the swinging of the mixing barrel 11, reduce the force applied to the base 10, and ensure the stable installation of the base 10.

[0024] The motor output shaft is fixedly connected to the main driving rod 22, and the motor drives the main driving rod 22 to drive the bevel gear 23 at the end of the main driving rod 22 to rotate. The bevel gear 23 pushes the bevel gear 23 on the wall of the connecting shaft 12 to rotate, and the driving gears 21 at the ends of the two connecting shafts 12 are meshed with each other to achieve reverse motion. The two mixing barrels 11 can keep swinging in the opposite direction. When the two mixing barrels 11 are away from each other, the motor does not do work. When the two mixing barrels 11 swing relative to each other, the motor cooperates with the accelerated motion of the mixing barrel 11 to accelerate the mixing barrel 11. Through the inertia of the mixing barrel 11, the two mixing barrels 11 can also swing back and forth several times. A stirring motor is provided in the mixing barrel 11. During the swinging process of the mixing barrel 11, the material will be squeezed to a certain extent in the cavity of the mixing barrel 11. With the stirring motor, premixing is achieved, and the mixing effect is good.

[0025] like Figure 1 and Figure 5As shown, the counterweight structure includes a counterweight block 30, a driven gear 31 and a connecting rod 32. The wall of the mixing barrel 11 is away from the connecting shaft 12 of the transmission assembly and is fixedly connected to the driven gear 31. The wall of the connecting rod 32 is fixedly connected to another identical driven gear 31. The two driven gears 31 are meshed with each other. The driven gear 31 on the wall of the connecting rod 32 is rotatably connected to the base 10. The counterweight block 30 is installed at the end of the connecting rod 32. The ends of the connecting shaft 12 of the two mixing barrels 11 away from the transmission assembly are both provided with the same counterweight structure. The counterweight block 30 forms a rectangular rod body structure, and the connecting rod 32 is horizontally broken into two parts, wherein the end face of one half of the connecting rod 32 is fixedly connected to an extension rod, and the cross section of the other half of the connecting rod 32 is provided with a sliding groove, and the half of the connecting rod 32 with the sliding groove is threadedly connected to The positioning screw and the wall surface of the extension rod are linearly provided with positioning holes, and the positioning bolts can be inserted into the positioning holes to lock the position of the extension rod. The counterweight block 30 is fixedly connected to the end of the lower half of the connecting rod 32, and the driven gear 31 connected thereto is driven to rotate through the connecting shaft 12, and the driven gear 31 drives the other driven gear 31 to move in the opposite direction, and then the other driven gear 31 can push the connecting rod 32 and the counterweight block 30 to swing, and further balance the eccentric force caused by the swinging process of 11. The counterweight is increased by the counterweight block 30, and the inertia of the swinging of the mixing barrel 11 is increased. Even if the motor of the driving assembly stops working, the two mixing barrels 11 can still continue to swing several times by inertia. Although it is more laborious to push the mixing barrel 11 to start, after the mixing barrel 11 swings, it is more conducive to the reciprocating swing of the mixing barrel 11.

[0026] By pulling the half of the connecting rod 32 away from the driven gear 31, the connecting rod 32 drives the extension rod to slide in the sliding groove, and the positioning bolt is turned into the positioning hole, so that the position of the extension rod is locked, and then the swing radius of the counterweight block 30 can be adjusted within a certain range, and can be adjusted according to the amount and density of the premixed material. It has a certain degree of adjustability and is more flexible to use.

[0027] The working principle of the utility model is as follows: the motor output shaft is fixedly connected to the main driving rod 22, and the motor drives the main driving rod 22 to drive the bevel gear 23 at the end of the main driving rod 22 to rotate, and the bevel gear 23 pushes the bevel gear 23 on the wall of the connecting shaft 12 to rotate, and the driving gears 21 at the ends of the two connecting shafts 12 are meshed with each other to realize reverse motion, and the two mixing barrels 11 can keep swinging in the reverse direction, pulling the half of the connecting rod 32 away from the driven gear 31, and the connecting rod 32 drives the extension rod to slide in the sliding groove, and the positioning bolt is rotated to enter the positioning hole, and the position of the extension rod is locked, so that the swing radius of the counterweight block 30 can be adjusted within a certain range, and the connecting shaft 12 drives the driven gear 31 connected thereto to rotate, and the driven gear 31 drives the other driven gear 31 to move in the reverse direction, and then the other driven gear 31 can push the connecting rod 32 and the counterweight block 30 to swing, and the eccentric forces generated when the two mixing barrels 11 swing offset each other in part.
