DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely part of the embodiments of the present application, rather than all the embodiments.

[0024] With reference to Figures 1-3 A kind of dry mixing device for plugging agent production, including stirring tank 1, rotating shaft 2 is rotationally arranged in stirring tank 1, motor 3 of driving rotating shaft 2 rotation is fixedly installed on the top surface of stirring tank 1, rotating shaft 2 lower part is fixedly sleeved with helical blade 4.Helical blade 4 cooperates with rotating shaft 2 and is in the shape of spiral auger, to stir and tumble the raw materials in stirring tank 1, realize mixing effect.Stirring tank 1 bottom is equipped with discharge gate and valve, since discharge gate and valve are prior art, it is more common in the field of stirring tank, but more redundant description.

[0025] With reference to Figures 2-4 Stirring tank 1 top surface one side is provided with feed inlet, and funnel 5 for feeding is fixedly connected at feed inlet, fixed rod 6 is fixedly arranged in the middle of funnel 5, fixed rod 6 top end is fixedly connected in the middle of funnel 5 by fixed frame 19, roller 7 is movably sleeved in the lower part of fixed rod 6, cavity 8 is arranged in the lower end of roller 7, cylindrical fixed block 9 located in cavity 8 is fixedly connected to the lower part of fixed rod 6, oblique oval sliding groove 10 is arranged on the outer side of fixed block 9, sliding block 11 is fixedly connected to the inner side wall of roller 7, and cooperates with sliding groove 10.

[0026] Roller 7 below is equipped with rotating block 12, and transmission column 13 is fixedly connected to the top surface of rotating block 12, and transmission column 13 passes through roller 7 and extends into cavity 8, and the inner side top of stirring tank 1 is equipped with transmission assembly for driving rotating block 12 to rotate by rotating shaft 2.

[0027] The dry mixing device for plugging agent production, when using, raw materials are put into funnel 5, motor 3 is started and rotating shaft 2 is driven to rotate, rotating shaft 2 drives rotating block 12 to rotate through transmission assembly, rotating block 12 drives roller 7 to rotate through transmission column 13, and sliding block 11 in the inside of roller 7 moves on sliding groove 10. Since sliding groove 10 is oblique oval, roller 7 rotates and moves up and down at the same time, so that the blocky material in funnel 5 is crushed. After raw materials enter stirring tank 1, stirring and mixing are realized by rotating shaft 2 cooperating with helical blade 4, after completion, valve is opened and discharged from discharge gate.

[0028] With reference to Figure 5 Transmission assembly includes two pulleys 14 respectively sleeved on the upper part of rotating shaft 2 and the outer side of rotating block 12, and transmission belt 15 is commonly sleeved on the outer side of two pulleys 14.The transmission assembly, by rotating belt cooperating with pulley 14, realizes the transmission of rotating shaft 2 to rotating block 12.

[0029] In order to avoid the raw materials entering the transmission assembly when feeding, the mounting box 16 is fixedly connected to the inner top wall of the stirring tank 1, the rotating block 12 is rotationally connected to the inner bottom wall of the mounting box 16, and the transmission assembly is located in the interior of the mounting box 16, thereby providing support for the rotating block 12 through the mounting box 16 and protecting the transmission assembly from interference.
