Description

Technical Field

[0001] This utility model relates to the field of mushroom stick technology, and in particular to a mushroom stick negative pressure water replenishment machine. Background Technology

[0002] After harvesting mushroom spawn, the weight of the spawn drops significantly, indicating severe moisture deficiency. This inhibits mycelial growth and fruiting body formation, necessitating timely water replenishment. Failure to do so will result in excessively low moisture content in the spawn, leading to excessive mycelial loss and death, ultimately resulting in fungal infection and rotting or disintegration of the spawn. Various methods exist for replenishing spawn, with injection and soaking being commonly used in production. Soaking involves puncturing several holes in the spawn with nails and immersing them in a water tank (cylinder, ditch) until the required moisture content is achieved. This is a traditional method, ensuring even and thorough soaking, rapid water absorption, and concentrated fruiting, but it is labor-intensive, and the spawn is prone to breakage or disintegration. Injection uses specialized injection needles, requiring manual watering of each spawn individually. This method is wasteful of water, and injection needles can cause uneven water distribution, resulting in insufficient watering in areas with dense mycelium, negatively impacting mushroom growth. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a negative pressure water replenishment machine for mushroom sticks. This water replenishment machine utilizes a vacuum pump to draw air out of the water replenishment tank, creating negative pressure inside. This causes most of the air in the mushroom sticks and the cavity to be drawn out, deforming the mushroom sticks. When the pressure returns to normal, the mushroom sticks return to their original shape and simultaneously draw in water. The water replenishment time is short, the efficiency is high, and water can be fully and evenly replenished.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A negative pressure water replenishment machine for mushroom cultivation includes a machine base, on which a water replenishment tank is installed. The top of the water replenishment tank is fitted with a flip-open lid. A flip-open pressure screen is rotatably connected inside the opening of the water replenishment tank. A vacuum pump and an air-water separator are installed inside the machine base. The air extraction end of the air-water separator is connected to an air extraction hose, the end of which extends to the lid for drawing air from inside the water replenishment tank. The air outlet end of the air-water separator is connected to the vacuum pump via an air outlet pipe. A water inlet is provided on one side of the bottom of the water replenishment tank.

[0005] Preferably, a pair of large wheels are installed on both sides of the bottom of the machine base, and a pair of steering wheels are installed on the front side of the bottom of the machine base.

[0006] Preferably, the bottom of the gas-water separator is provided with a drain outlet extending out of the bottom of the machine, and a drain valve is installed in the drain outlet. An air inlet is provided on one side of the gas-water separator, and a first solenoid valve is installed at the connection between the air inlet and the air extraction hose.

[0007] Preferably, a second solenoid valve is installed inside the water inlet.

[0008] Preferably, a controller is installed on the top of the tank cover, and a water level switch electrically connected to the controller is also installed inside the tank cover. A water filling button electrically connected to the controller is installed on the front side of the water supply tank. The controller extends to the bottom of the machine through a wiring conduit. A switch box connected to the wiring conduit is installed inside the bottom of the machine, and a 3P air switch is installed inside the switch box.

[0009] Preferably, a travel switch electrically connected to the controller is installed on the side wall of the tank cover. The trigger end of the travel switch is installed on the side wall of the tank cover, and the start end of the travel switch is installed on the corresponding side of the water tank opening. It is used to trigger the vacuum pump when the tank cover is closed. A negative pressure gauge and a glass observation hole are installed on the top of the tank cover, and a manual exhaust valve is installed on the top of the water tank.

[0010] Preferably, a silicone sealing strip is installed on the contact edge between the tank lid and the water tank.

[0011] Preferably, both sides of the water tank opening are rotatably connected to a gas spring hydraulic rod, and the telescopic end of the gas spring hydraulic rod is rotatably connected to the corresponding side of the tank cover.

[0012] The beneficial effects of this utility model are as follows: 1. The water replenishment machine uses a vacuum pump to draw air out of the water replenishment tank, creating negative pressure inside. This causes most of the air in the mushroom sticks and the cavity to be drawn out, deforming the mushroom sticks. When the pressure returns to normal, the mushroom sticks return to their original shape and simultaneously draw in water. The water filling time is short, the efficiency is high, and the water can be filled fully and evenly.

[0013] 2. By using a series-connected air-water separator, the moisture in the air can be filtered out when the air in the water supply tank is drawn in before entering the vacuum pump, thus avoiding damage to the vacuum pump and enabling continuous suction operation.

[0014] 3. By installing a limit switch, the limit switch will be automatically triggered after the cover is closed, and the vacuum pump will start to evacuate the air. The negative pressure gauge will provide feedback on the internal pressure value.

[0015] 4. By setting the water filling button, pressing it will open the second solenoid valve, and water will be added to the water tank through the water inlet. A water level switch installed inside the cover can monitor the water level and automatically stop adding water after reaching a certain level. Attached Figure Description

After the tank cover 6 is opened, the gas spring hydraulic rods 24 can automatically support the tank cover 6.

[0029] Open the lid 2, then flip the pressure screen 25, place the mushroom sticks into the water supply tank 2, and then press the mushroom sticks down with the pressure screen 25. Fill the water supply tank 2 with water until the water level reaches the height of the pressure screen 25. Close the lid 6, trigger the start-up of the limit switch 22, and start the vacuum pump 16 via the controller 8. The air in the water supply tank 2 is drawn into the air-water separator 20 through the suction hose 10. The separated water is discharged through the drain port 4, and the dry gas enters the vacuum pump 16 through the air outlet pipe 17. The vacuum pump 16 is then controlled by the negative pressure gauge. 9. Observe the internal pressure value 9. Stop pumping air after reaching a certain pressure. At this time, press the water filling button 14. The second solenoid valve 12 opens and water is added to the water replenishment tank 2 through the water inlet 13.
