Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry waste resource utilization technology, specifically to an environmentally friendly fermentation device for treating agricultural and forestry waste. Background Technology

[0002] Fermentation of agricultural and forestry waste relies on aerobic or anaerobic microbial fermentation technology to treat agricultural and forestry organic solid waste such as crop straw, fruit tree branches, vines, fallen leaves, weeds, garden pruning materials, and mushroom residue in a harmless, reduced, and resource-oriented manner. During the fermentation process, sampling and testing are usually required, and biosensors are used to detect whether there are factors such as excessive pollutants, in order to ensure the effectiveness of fermentation.

[0003] Existing fermentation equipment typically involves multiple sampling tests, which can easily leave residues from previous samples on the surface of the sampling container. This contamination between samples from multiple tests affects the accuracy of the results and reduces the precision of the analysis. Therefore, we propose an environmentally friendly fermentation device for treating agricultural and forestry waste.

By setting the slant plate 2119, while the annular cleaning brush 2109 is rotating and cleaning, it can drive the annular cleaning brush 2109 to move and clean, thereby further improving the cleaning effect, effectively removing sample residues, and ensuring the accuracy of subsequent testing.

[0023] Two stabilizing telescopic rods 2116 are fixedly connected to one side of the first conveying ring 2114.

By setting a rectangular hollow rod 2207, the three second delivery rings 2214 can be interconnected. After the cleaning and disinfecting solution enters into one second delivery ring 2214, it can enter into the other two connected second delivery rings 2214 through the rectangular hollow rod 2207, thereby delivering the cleaning and disinfecting solution. Finally, it can enter into the circular hollow plate 2212 and be sprayed out, so that it can rinse and clean the inside of the sampling cylinder 310, ensuring the cleanliness of the sampling cylinder 310, preventing sample contamination caused by internal sample residue, and thus improving the accuracy of subsequent testing.

[0026] A push tube 2210 is provided on one side of the insertion tube 2211. A first spring 2209 is movably sleeved on the surface of the push tube 2210.

This is the prior art and will not be elaborated on here. By setting the support rod 2204 and the limiting groove 2203, the second conveying ring 2214 can be supported and limited to ensure the stability of the movement of the second conveying ring 2214.

[0027] By using the sweeping unit 21 and the pushing unit 22 in combination, the purpose of cleaning the adhering residue can be achieved. After the sampling test is completed, the surface of the sampling cylinder 310 can be cleaned so that the residue adhering to the surface of the sampling cylinder 310 can be removed. In the next sampling test, the previous test sample will not be mixed, thus preventing the mixing of different batches of samples and ensuring the accuracy of subsequent multiple tests.

[0028] The specific implementation of this embodiment is as follows: After a sampling test is completed, the first electric telescopic rod 2202 is extended and retracted by an external controller and power supply, which drives the guide telescopic rod 306 to move. The insertion ring 2205 drives the insertion rod 2206 to move, and the insertion rod 2206 drives the connected second conveying ring 2214 to move, causing the second hollow ring 2208 to approach the push tube 2210. The push tube 2210 passes through the through hole 316 and contacts the second hollow ring 2208, thereby inserting the insertion tube 2211 into the push tube 2210 and connecting it. At this time, the first electric telescopic rod 2202 continues to extend, allowing the push tube 2210 to move, thereby compressing the first spring 2209. 10 can move the circular hollow plate 2212, thereby pushing the sample in the sampling cylinder 310 out and allowing it to fall through the circular hole on one side of the insertion cylinder 301, thus cleaning the inside of the sampling cylinder 310. After being pushed out, the circular hollow plate 2212 can be moved back to its original position, allowing the first telescopic hose 2105 to be connected to the pump body to draw in the cleaning and disinfecting solution. The drawn cleaning and disinfecting solution can enter the connecting pipe 2115 through the first telescopic hose 2105, and then be transported into the second telescopic hose 2201 through the connecting pipe 2115, and then into the second conveying ring 2214. Finally, it can be transported into another connected second... The sample cylinder 310 is moved into the second hollow ring 2208 through the conveying ring 2214. At this point, the cleaning and disinfecting solution is delivered into the circular hollow plate 2212 via the insertion tube 2211 and the pushing tube 2210. The circular hollow plate 2212 has outlet holes on its surface, allowing the cleaning and disinfecting solution to spray out. Simultaneously, the pushing tube 2210 moves the circular hollow plate 2212, thus rinsing and cleaning the inside of the sampling cylinder 310. After the circular hollow plate 2212 is removed, the continued extension of the first electric telescopic rod 2202 moves the sampling cylinder 310 out of the insertion tube 301 and into the annular cleaning brush 2109. The drive motor 2112 drives the connected rotating rod 2102 to rotate, causing the second synchronous wheel 21 on it to rotate. The first synchronous belt 2106 and the second synchronous belt 2108 rotate, causing the remaining second synchronous pulleys 2111 and the first synchronous pulley 2110 to rotate, thereby driving multiple rotating rods 2102 to rotate. The limiting rods 2118 on the surface of the rotating rods 2102 can drive the fixed ring 2120 to rotate, thereby driving the first hollow ring 2103 to rotate within the first conveying ring 2114. The short tube 2113 drives the annular cleaning brush 2109 to rotate, allowing the annular cleaning brush 2109 to clean the surfaces of the sampling cylinder 310 and the circular hollow plate 2212. Simultaneously, the rotating rods 2102 rotate, driving the swashplate 2119 to rotate, which in turn pushes and pulls the swing rod 2121.The short plate 2117 reciprocates to pull the first conveying ring 2114, while the stabilizing telescopic rod 2116 extends and retracts to stabilize the position of the first conveying ring 2114. The first conveying ring 2114 can reciprocate to pull the first hollow ring 2103, allowing the annular cleaning brush 2109 to move back and forth while rotating and cleaning, thereby improving the cleaning effect of the annular cleaning brush 2109. At the same time, the first telescopic hose 2105 delivers the cleaning and disinfecting solution into the connecting pipe 2115, which can enter the first The sample enters the short tube 2113 through the first hollow ring 2103 within the conveying ring 2114, and then through the short tube 2113 into the annular cleaning brush 2109. The annular cleaning brush 2109 also has outlet holes on its inner wall, allowing the cleaning and disinfecting solution to be sprayed out. This effectively cleans the sampling cylinder 310 and the circular hollow plate 2212, removing sample residue and preventing contamination during subsequent sampling and testing, thus ensuring the accuracy of the data detection.

[0034] By setting up the sampling and testing mechanism 3, the purpose of quantitative sampling and testing can be achieved.

This reduces the likelihood of deviations in the test data due to inconsistent sampling quantities, thereby further improving the accuracy of the test and guaranteeing its precision.

[0035] The specific implementation of this embodiment is as follows: When sampling is required, the second electric telescopic rod 302 can push the fixed rod 305 downward, which in turn moves the three insertion cylinders 301 downward.

After the insertion cylinders 301 are inserted into the fermentation tank 1, the extension of the second electric telescopic rod 302 can drive the guide telescopic rod 306 to move. The guide telescopic rod 306 pushes the support ring 318 connected to it to move. The support ring 318 can push the collar 320 to move on the spiral rod 312, through the spiral hole. The engagement of 319 and the screw rod 312 causes the collar 320 to rotate on the support ring 318, thereby driving the linkage plate 313 to rotate from a vertical to a horizontal state. As the linkage plate 313 rotates, it slides on the sliding rod 314, simultaneously driving the sliding rod 314 to rotate. This causes the sliding rod 314 to drive the rotating disk 309 to rotate, allowing the short block 321 to move through the arc-shaped hole 308. Simultaneously, under the limiting effect of the rectangular groove 307, the short block 321 can drive the stop blocks 317 away from each other, thus eliminating the obstruction of the stop blocks 317 to the insertion cylinder 301. A seal with a circular hole on one side allows the linkage plate 313 to contact the sampling cylinder 310 through the continued extension of the first electric telescopic rod 2202. This allows the pushable sampling cylinder 310 to be moved out of the insertion cylinder 301, enabling multiple sampling cylinders 310 to be moved out simultaneously. This allows for multi-point stratified sampling and testing of the fermentation material, ensuring the consistency of the sampling amount and thus the accuracy of the test. After sampling and testing are completed, the sampling cylinder 310 can be moved back into the insertion cylinder 301, and the second electric telescopic rod 302 shortens to reset the insertion cylinder 301. After resetting, the insertion rod 2206 will be inserted into the insertion ring 2205. During cleaning, when the guide telescopic rod 306 is pushed by the first electric telescopic rod 2202, the insertion rod 2206 will move along with the guide telescopic rod 306. After the linkage plate 313 rotates to a horizontal state, the push tube 2210 will be aligned with the through hole 316, so that it can pass through the through hole 316 and connect with the insertion tube 2211, thereby cleaning the sampling cylinder 310 in the subsequent process. This prevents sample residue from causing sample mixing during subsequent sampling and improves the accuracy of detection.
