Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0033] With reference to Figures 1-9 The present application provides a technical solution: an enzymolysis device for preparing earthworm organic water-soluble fertilizer, comprising an enzymolysis tank 1, a sampling port 2 arranged on the side wall of the enzymolysis tank 1, a sampling unit 3 arranged on the inner side of the sampling port 2, the sampling unit 3 being capable of ensuring that the sample is in the same environment in the enzymolysis tank 1 after sampling, and the dissolved oxygen being less than or equal to 0.5 mg / L; the sampling unit 3 comprises a sampling head 4, a sampler 6, a driving mechanism, an exhaust mechanism and a gas injection mechanism; the sampling head 4 is horizontally and slidingly connected with the sampling port 2; the sampler 6 is inserted with the sampling head 4; a channel one 5 is arranged on the inner side of the sampling head 4; a feeding port 7 capable of communicating with the channel one 5 is arranged on the sampler 6; a sealing ring 8 is elastically and slidingly connected with the circumferential side wall of the sampler 6 along the axial direction thereof; the driving mechanism is arranged on the side of the sampling head 4 and is used for driving the horizontal movement of the sampling head 4; the exhaust mechanism is arranged on the inner side of the sampler 6; and the gas injection mechanism is arranged on the inner side of the sampling port 2 and is used for injecting the protective gas at the top of the enzymolysis tank 1 into the sampler 6 before the sampling head 4 moves into the inside of the enzymolysis tank 1, so that the air in the sampler 6 is extruded out through the exhaust mechanism and the protective gas is filled in the sampler 6.

[0034] With reference to Figures 1-6 Earthworm paste and water are added into the enzymolysis tank 1 from the feeding port at the top of the enzymolysis tank 1, and the volume ratio of the earthworm paste to the water is 1:5; for example, 10 kg of earthworm paste needs to be added with 50 kg of water; the stirring mechanism in the enzymolysis tank 1 is started to stir (200 rpm); the enzymolysis tank 1 is kept at a constant temperature of 50°C, and then the neutral protease solution is injected; nitrogen gas is introduced into the enzymolysis tank 1 at the top to disperse air, reduce the oxygen concentration in the gas phase in the enzymolysis tank 1, and maintain a positive pressure in the enzymolysis tank 1; nitrogen gas is introduced into the enzymolysis tank 1 at the bottom through the microporous aeration pipe to form gas circulation, homogenize the material and control oxygen; when sampling detection is needed, for example, the sampling head 4 is moved to the sampling port 2, the sampler 6 is inserted into the channel one 5, and the protective gas in the sampler 6 is injected into the enzymolysis tank 1 through the gas injection mechanism, so that the air in the sampler 6 is extruded out through the exhaust mechanism, and the protective gas is filled in the sampler 6. Figure 7As shown, the sampler 6 is inserted into the sampling head 4 and docked with the sampling head 4. At this time, the left side wall of the sealing ring 8 fits with the right side wall of the sampling head 4, and the pre-tightening force applied by the spring 1 can make the sealing ring 8 fit tightly with the sampling head 4 to ensure the sealing between the sampling head 4 and the sampler 6, and the sampler 6 is relatively fixed to the sampling head 4, and the feed port 7 is aligned with the bottom end of the channel 1 5; then the driving mechanism drives the sampling head 4 and the sampler 6 to move synchronously toward the inside of the enzymolysis tank 1; after the sampling head 4 moves a short distance, the top of the channel 1 5 is connected to the gas injection mechanism; the gas injection mechanism injects the protective gas nitrogen at the top of the enzymolysis tank 1 into the sampler 6 through the channel 1 5 and the feed port 7, and the air in the sampler 6 is squeezed out from the exhaust mechanism; at this time, the gas environment in the channel 1 5, the feed port 7 and the sampler 6 is in the same state as the gas environment in the enzymolysis tank 1; then the driving mechanism drives the sampling head 4 and the sampler 6 to continue to move toward the inside of the enzymolysis tank 1, as shown Figure 9 As shown, until the top of channel 1 5 moves into the enzymolysis tank 1, and then the sample slurry enters the sampler 6 from channel 1 5 through the feed port 7; after the sampling is completed, the driving mechanism drives the sampling head 4 and the sampler 6 to move outward to Figure 7 Then remove the sampler 6 from the sampling head 4, seal the feed port 7 again with the sealing ring 8, and then send the sample in the sampler 6 for inspection; Figure 4 As shown, the middle section of channel 1-5 is set to be inclined. After the sampler 6 is separated from the sampling head 4, the slurry remaining in channel 1-5 will flow out of channel 1-5, avoiding the slurry remaining in channel 1-5 and affecting the next sampling. After each sampling, channel 1-5 can be rinsed with clean water to keep channel 1-5 better clean. The present invention is provided with the sampling head 4, sampler 6, sealing ring 8, exhaust mechanism, gas injection mechanism and driving mechanism. After the sampling head 4 and the sampler 6 are docked, the sealing ring 8 can ensure the seal between the sampling head 4 and the sampler 6. During the process of the driving mechanism driving the sampling head 4 to move into the enzymolysis tank 1, the gas injection mechanism injects the protective gas on the top of the enzymolysis tank 1 into the sampler 6 and squeezes out the air in the sampler 6 through the exhaust mechanism, so that the gas environment in the sampler 6 is in the same state as the gas environment in the enzymolysis tank 1, avoiding the increase of dissolved oxygen content after the sample sent for inspection enters the sampler 6, thereby ensuring the accuracy of sample detection.

[0035] Specifically, such as Figures 2-4 As shown, a piston 9 is slidably installed in the sampler 6, and the piston 9 is fixedly connected to a return spring 26, and the return spring 26 is fixedly connected to the sampler 6 at one end away from the piston 9; a limiting mechanism is provided on the side of the piston 9, and the limiting mechanism is used to limit the piston 9, and can cancel the limitation of the piston 9 when the sampling head 4 moves into the enzymatic hydrolysis tank 1; the limiting mechanism includes a clamping block 15, and the clamping block 15 is rotatably connected to the sampler 6; a traction rope 17 is fixedly connected to the clamping block 15, and the traction rope 17 is fixedly connected to a slide rod 16 at one end away from the clamping block 15, and the slide rod 16 is slidably connected to the sampler 6.

[0037] Specifically, as shown in Figures 3-5 , the exhaust mechanism includes a channel two 10, the channel two 10 is arranged in the inside of the piston 9, and the channel two 10 is elastically and slidably connected with a blocking block 11, the blocking block 11 is provided with a jack 12 for driving the blocking block 11 to move, and the jack 12 is fixedly connected with the sampler 6; the blocking block 11 is provided in a circular truncated cone shape, and the channel two 10 close to the blocking block 11 is provided in a circular truncated cone shape matched with the blocking block 11.

[0038] Reference Figure 5 When the left wall of the piston 9 is in close contact with the inner wall of the sampler 6, the jack 12 acts on the blocking block 11, and the channel two 10 is in an open state; when the gas injection mechanism injects the protective gas in the enzymolysis tank 1 into the channel one 5 and the sampler 6, the air in the channel one 5 and the sampler 6 is discharged from the channel two 10; before the sampling head 4 enters the enzymolysis tank 1, the clamping block 15 cancels the limitation of the piston 9, and after the piston 9 moves to the right, the blocking block 11 moves to the left to block the left end of the channel two 10 under the action of the elastic force of the spring two connected with the blocking block 11; the left end of the blocking block 11 and the channel two 10 are both provided in a circular truncated cone shape, and the left end is smaller than the right end, so that the elastic force of the spring two and the air pressure can tightly block the channel two 10, thereby avoiding the air from entering the sampler 6 to pollute the sample.

[0039] Specifically, as shown in Figure 3 and Figure 4As shown, the sampling head 4 is provided with a slot 13, and the sampler 6 is fixedly connected with an insertion block 14 capable of being inserted into the slot 13; the insertion block 14 and the slot 13 are both rectangular, and the insertion of the insertion block 14 and the slot 13 can realize the positioning of the sampler 6. The abutting end portions of the sampling head 4 and the sampler 6 can be provided with magnetic members (such as magnets), and the relative fixation of the sampling head 4 and the sampler 6 can be realized through the mutual attraction of the magnetic poles and the limiting of the insertion block 14.
