[0025] Example

[0026] The utility model provides a high-efficiency and environment-friendly mixing device for composite biological organic fertilizer, which mainly comprises a mixing cylinder 1, a mixing mechanism 2 and a power mechanism 3.

[0027] The mixing drum 1 includes a plurality of outer drum sections 11, which are detachably connected by bolt fasteners. The outer drum 11 is fixed to a machine base. The power mechanism 3 is also installed on the machine base. The power mechanism 3 includes a motor and a plurality of transmission members. The output shaft of the motor drives the mixing mechanism 2 located in the mixing drum 1 to stir the feces through the plurality of transmission members. The transmission member can be a belt drive or a gear drive. Since the structure of the power mechanism 3 is a prior art, it will not be described in detail.

[0028] The mixing cylinder 1 also includes an inner cylinder 12, an inlet 13, an outlet 14 and a stripping piece 15. The inner cylinder 12 is fixed at intervals in each section of the outer cylinder 11, and a cavity is retained between the outer cylinder 11 and the inner cylinder 12. The inlet 13 and the outlet 14 opened on the inner cylinder 12 are respectively located on both sides of the top of the inner cylinder 12, wherein the side of the inlet 13 away from the outlet 14 extends upward to form a blocking surface and is fixedly connected to the outer cylinder 11, and the side of the outlet 14 away from the top of the inner cylinder 12 is inclined toward the inside of the inner cylinder 12, so that metal impurities can slide from the top of the inner cylinder 12 over the opening of the outlet 14 to the bottom of the cavity.

[0029] The mixing mechanism 2 includes a rotating rod 21, an elastic rod 22, a magnetic rod 23, and a stirring blade 24. The rotating rods 21 are connected synchronously by a snap-in plug-in connection. One of the rotating rods 21 is connected to the output shaft of the motor through a transmission member so that the motor can drive the rotating rod 21 to rotate. A plurality of stirring blades 24 are fixed on each section of the rotating rod 21. The rotating rod 21 and the magnetic rod 23 are connected by the elastic rod 22. One section of the elastic rod 22 is detachably connected to the rotating rod 21, and the other section is fixedly connected to the magnetic rod 23. The two sections of the elastic rod 22 are elastically slidably connected.

[0030] Due to the existence of elastic force, when the magnetic rod 23 rotates in the inner tube 12, it will always rotate in contact with the inner wall of the inner tube 12. When the magnetic rod 23 rotates to the position of the outlet 14, it will pop out from the outlet 14 under the action of the elastic force and move in the cavity between the inlet 13 and the outlet 14. When the magnetic rod 23 moves to the position of the inlet 13, it will be blocked by the connecting surface between the inlet 13 and the outer tube 11. The elastic rod 22 is pressed to drive the magnetic rod 23 to enter the inner tube 12 again, and this process is repeated.

[0031] Preferably, a plurality of rollers are rotatably connected to the magnetic rod 23 , and the rollers reduce the resistance of the magnetic rod 23 when it moves against the inner wall of the inner cylinder 12 .

[0032] A stripping member 15 is disposed between the inlet 13 and the outlet 14 in the cavity.

[0033] In one case of this embodiment, the stripping member 15 is a rubber convex block that can be deformed. Two stripping members 15 are symmetrically fixed on the outer wall of the inner cylinder 12 and the inner wall of the outer cylinder 11. The magnetic rod 23 passes between the two stripping members 15 and squeezes the two stripping members 15 during the passing process. The metal impurities on the magnetic rod 23 are squeezed by the stripping members 15 and the metal impurities adsorbed on the moving magnetic rod 23 are stripped off, so that the metal impurities can roll toward the outlet 14 side and fall into the bottom of the cavity after passing through the opening of the outlet 14.

[0034] Furthermore, an opening and closing door may be hinged at the bottom of the outer cylinder 11, and the opening and closing door may be opened when necessary to pour out the metal impurities at the bottom of the cavity.

[0035] In another situation of this embodiment, the stripping piece 15 is two overlapping rubber sheets. When the magnetic rod 23 passes through the overlapping stripping piece 15, the stripping piece 15 opens and adheres to the surface of the magnetic rod 23. The blocking effect of the rubber sheet will scrape off the metal impurities adsorbed on the magnetic rod 23; when the magnetic rod 23 leaves the stripping piece 15, the two rubber sheets are reset again and overlap each other.

[0036] In the third case of this embodiment, the stripping member 15 is two metal plates, and the two metal plates are elastically and slidably connected to the corresponding outer cylinder 11 and inner cylinder 12 respectively. When not in contact with the magnetic rod 23, the two stripping members 15 are close to each other under the action of elastic force; when in contact with the magnetic rod 23, the magnetic attraction drives the metal plate to always adhere to the magnetic rod 23, and gradually pushes out the metal impurities adsorbed on the magnetic rod 23 during the movement of the magnetic rod 23, until the magnetic rod 23 leaves the stripping member 15, and the stripping member 15 closes again under the action of elastic force to prevent the stripped metal impurities from falling back into the inner cylinder 12 from the inlet 13 and the outlet 14.

[0037] Preferably, the contact surface between the metal plate and the magnetic rod 23 is an inclined surface, which facilitates the extrusion of the magnetic rod 23 .

[0038] Furthermore, a rubber baffle can be fixed on the outlet 14. When the magnetic rod 23 passes through the outlet 14, the rubber baffle is pushed open by the magnetic rod 23. The magnetic force of the magnetic rod 23 can adsorb metal impurities on the magnetic rod 23 and will not be scraped off by the rubber baffle. When the magnetic rod 23 leaves the outlet 14, the rubber baffle re-closes the opening of the outlet 14 under the reset trend, so as to reduce the probability of metal impurities falling from the outlet 14 into the inner tube 12 when crossing the outlet 14.

[0039] In summary, the technical solution of the present application can be briefly described as: the traditional single cylinder is changed into a double cylinder of an outer cylinder 11 and an inner cylinder 12, so that while the mixing mechanism 2 is mixing feces, the magnetic rod 23 crosses between the outer cylinder 11 and the inner cylinder 12, and the stripping member 15 squeezes the magnetic rod 23 to discharge metal impurities from the cavity between the outer cylinder 11 and the inner cylinder 12, thereby realizing the two-in-one function of mixing feces and removing metal impurities, thereby improving the mixing efficiency of feces.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
