[0034] In the production of microbial fertilizer, the cultured bacteria are added to the bacteria container connected to the bacteria tube 91, the water pipe 9 is connected to the water source, the feed pipe 2 is connected to various raw material containers, the stirring motor 3 starts to run and drives the stirring shaft 11 to rotate, the screw shaft 22 connected to the stirring shaft 11 rotates to quantitatively transport the raw materials to the stirring drum 1, so that the raw materials can be mixed in a fixed ratio, the stirring rod 41 and the screw rod 42 fixedly connected to the stirring shaft 11 rotate, the stirring rod 41 mixes the raw materials, and the screw rod 42 pushes the raw materials to move in the stirring shaft 11, and at the same time, the spray barrel 6 rotatably connected to the stirring shaft 11 extracts water and mixes and dilutes the bacteria during the rotation of the stirring shaft 11, and then sprays it in the mixture, so that the bacteria and the raw materials are fully mixed, and the efficiency of composting fermentation is accelerated, and the discharge screw 8 coaxially fixedly connected to the stirring shaft 11 rotates to discharge the mixed pile to start the composting fermentation process, which can continuously feed, stir and discharge, and has higher processing efficiency than batch stirring and mixing.

[0035] Example 2

[0036] like Figure 1-9As shown, a high-efficiency microbial fertilizer production mixer is based on Example 1. The stirring shaft 11 and the spiral shaft 22 are respectively connected to the contraction pulley 5, and the corresponding contraction pulleys 5 are connected by a transmission belt 52. The raw material ratio required for different soil conditions is different. Therefore, when the raw material ratio needs to be adjusted, it is achieved by changing the transmission ratio between the stirring shaft 11 and the spiral shaft 22. The contraction pulley 5 includes a center wheel 51 fixed on the stirring shaft 11 or the spiral shaft 22, and the center wheel 51 is fixedly connected to a gear frame 541. The gear frame 541 is rotatably connected to a contraction bevel gear 54, and the contraction bevel gear 54 rotates coaxially with the center wheel 51. The connected adjusting bevel gear 55 is meshed, and an air flow channel 211 is set inside the feeding shaft 21 and the stirring shaft 11. The air flow channel 211 is connected to the adjusting chamber 56. The adjusting plate 551 fixed on the outside of the adjusting gear slides in the adjusting chamber 56. Another adjusting plate 551 is fixed in the adjusting chamber 56. The adjusting chamber 56 is in a relatively sealed environment. The adjusting chamber 56 is connected to the air flow channel 211 in the middle of the feeding shaft 21. The adjusting bevel gear 55 is rotated by changing the pressure in the air flow channel 211, so that the retraction rod 57 is synchronously retracted or extended, thereby changing the circumferential length of the two retraction pulleys 5, thereby changing the transmission ratio and controlling the feeding ratio.

[0037] The air flow channel 211 inside the feeding shaft 21 and the stirring shaft 11 extends to the outside of the mixing drum 1, and is connected to the air flow channel 211 through an external pressurizing device to change the pressure in the adjusting chamber 56. When the pressure in the adjusting chamber 56 increases, the adjusting plate 551 slides in the adjusting chamber 56 under the action of pressure, and the adjusting bevel gear 55 fixedly connected to the adjusting plate 551 rotates, and the contraction bevel gear 54 meshing with the adjusting bevel gear 55 rotates on the gear rack 541. When the contraction bevel gear 54 rotates, the contraction rod 57 threadedly connected thereto slides relative to the center wheel 51, and the outer end of the contraction rod 57 is connected to the support sheet 53. The radius of the contraction pulley 5 formed by the expansion or contraction of multiple contraction rods 57 and the support sheet 53 changes, and the two contraction pulleys 5 are changed respectively, so that the transmission belt 52 is in a taut state, and the transmission ratio can be arbitrarily changed within a range to make the proportion of ingredients more accurate. It should be noted that in order to prevent the contraction rod 57 from rotating with the contraction bevel gear 54, the contraction rod 57 can be radially limited so that the contraction rod 57 can only move axially.

[0038] Example 3

[0039] like Figure 1-9As shown, a high-efficiency microbial fertilizer production mixer is based on Example 1. The stirring shaft 11 is rotatably connected to the spray barrel 6, one end of the spray barrel 6 is connected to the guide barrel 7, the guide barrel 7 is connected to the water pipe 9 and the bacterial seed tube 91, the water pipe 9 and the bacterial seed tube 91 pass through the stirring barrel 1 and are respectively connected to the water source and the bacterial seed container. The inner wall of the spray barrel 6 is divided into a plurality of spray channels 63, and a spray plug 62 is slidably connected in each spray channel 63. The spray plug 62 is rotatably connected to one end of the connecting rod 64, and the other end of the connecting rod 64 is rotatably connected to the eccentric shaft 65. The eccentric shaft 65 is eccentrically fixed to the stirring shaft 11, and a spray port is arranged on the side of each spray channel 63. A sealing sheet 61 is connected at each spray port. A mixing rod 72 is also fixed on the stirring shaft 11 in the guide barrel 7. The right end of the guide barrel 7 is connected to a one-way guide valve 71, and a slidable flow regulating plate 92 is arranged in the water pipe 9 and the bacterial seed tube 91.

[0040] When the stirring shaft 11 rotates, the eccentric shaft 65 connected eccentrically is driven to rotate. The spray plug 62 connected to the eccentric shaft 65 through the connecting rod 64 slides in the spray channel 63. The spray plug 62 can absorb water and drain water during the reciprocating sliding process. When draining water, the sealing piece 61 slides outward under the pressure, and the spray port is opened. The net ring 611 is connected inside the sealing piece 61, so that the spray water passes through the net ring 611 and is dispersed and sprayed out, so that the diluted bacteria and ingredients are mixed more evenly. When absorbing water, the sealing piece 61 seals the spray port, and the one-way guide valve 71 is opened. The dilution factor of the cultured bacteria can be changed by changing the flow cross-sectional area. The cultured bacteria can be mixed with the fertilizer ingredients after being diluted to a suitable multiple. After the water and cultured bacteria enter the guide tube 7, the mixing rod 72 connected to the stirring shaft 11 in the guide tube 7 mixes and dilutes the liquid entering the guide tube 7, so that the bacteria are evenly distributed in the diluted liquid.
