Description

Technical Field

[0001] This utility model relates to the field of edible fungi production and processing technology, specifically to a pre-wetting device for screening raw materials of edible fungi strains. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. Currently, the main raw materials used in the production of edible fungi in my country are agricultural and forestry wastes, such as wood chips and corn cobs. Before planting edible fungi spawn, the spawn needs to be pre-moistened.

[0003] Patent document CN220000239U discloses a pre-wetting device for raw materials of edible fungi spawn, specifically including a turning tank, a first pre-wetting component, and a second pre-wetting component. A rotating shaft is rotatably connected inside the turning tank, and stirring blades are fixed on the rotating shaft. A collection trough is opened at the bottom of the turning tank, and a seepage net is fixed inside the collection trough. A collection box is connected below the collection trough. The raw materials in the turning tank are pre-wetted through the stirring blades, the first spray nozzle, and the second spray nozzle, which increases the pre-wetting efficiency and effect of the raw materials. Excess water seeps into the collection box through the collection trough, the seepage net, and the collection box, avoiding the generation of wastewater that pollutes the environment.

[0004] However, in the process of realizing this utility model, the inventors discovered the following problems with the existing technology: the above-mentioned pre-wetting device uses a permeable net to filter out excess water after pre-wetting the edible fungi spawn. The drainage operation through the permeable net mainly relies on the gravity of the water to achieve the downward flow effect, which has the defect of slow drainage speed. Furthermore, as the water content of the spawn gradually decreases, some water is difficult to separate from the spawn, resulting in incomplete drainage. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model provides a pre-wetting device for screening raw materials of edible fungi strains.

[0006] Therefore, the technical solution of this utility model is as follows: a pre-wetting device for screening raw materials of edible fungi spawn, including a mounting frame, two support shafts symmetrically arranged at the upper end of the mounting frame, a processing cylinder fixedly installed at one end of the two support shafts that are close to each other, a screen cylinder rotatably connected to the inner wall of the processing cylinder through a sealed bearing, the left and right ends of the screen cylinder extending to the left and right sides of the processing cylinder respectively, a screen hole is opened on the surface of the screen cylinder on the inner side of the processing cylinder, a pre-wetting component is arranged at the right end of the processing cylinder corresponding to the screen cylinder, and a centrifugal dehydration component is arranged at the left end of the processing cylinder corresponding to the screen cylinder;

[0007] The pre-wetting assembly includes a first fixed frame fixedly installed at the right end of the processing cylinder. A central tube is fixedly installed on the surface of the first fixed frame. The central tube is rotatably connected to the screen cylinder through a sealed bearing. A water inlet pipe is fixedly installed at the right end of the central tube. The left end of the central tube extends into the interior of the screen cylinder and has a water outlet hole.

[0008] The centrifugal dewatering assembly includes a second fixed frame fixedly installed at the left end of the processing cylinder. A geared motor is fixedly installed on the left side of the second fixed frame, and the output end of the geared motor is fixed to the left end of the screen cylinder.

[0009] Furthermore, a material pipe is obliquely embedded on the right side of the sieve cylinder, and a drain pipe is embedded on the bottom side of the processing cylinder. Valves are provided on the surface of both the material pipe and the drain pipe, and the outlet end of the drain pipe is connected to an external water pipe. By setting the material pipe, keeping the opening of the material pipe facing upwards allows the inoculum to be added to the sieve cylinder, while keeping the opening of the material pipe facing downwards allows the inoculum to be removed from inside the sieve cylinder.

[0010] Furthermore, a stirring rod is fixedly installed on the surface of the central tube, and a shovel plate is fixedly installed at the end of the stirring rod away from the central tube. By setting the stirring rod and the shovel plate, when the sieve cylinder is driven to rotate by the geared motor, the stirring rod remains stationary with the central tube, and the inoculum moves relative to the stirring rod and the shovel plate. This allows the inoculum to be stirred using the stirring rod and the shovel plate, ensuring the uniformity of the inoculum pre-wetting during the pre-wetting stage. In addition, the shovel plate can prevent the sieve holes from becoming blocked.

[0011] Furthermore, the pre-humidification assembly also includes an input connector fixedly installed on the back of the mounting bracket. The support shaft on the back has a connecting cavity inside, and the inlet end of the water inlet pipe is connected to the connecting cavity. The end face of the support shaft on the back is rotatably connected to a rotating sleeve through a sealed bearing. The outlet end of the input connector is connected to the rotating sleeve. The input connector is connected to the rotating sleeve, the connecting cavity, and the inlet end of the water inlet pipe in sequence. By setting the input connector and the rotating sleeve, the input connector is connected to an external water supply pipeline, which can achieve the purpose of continuous water supply to the water inlet pipe.

[0012] Furthermore, the support shaft is rotatably connected to the mounting frame, and an inclined discharge assembly is provided between the mounting frame and the support shaft. The inclined discharge assembly includes a drive box fixedly mounted on the surface of the mounting frame. A hydraulic rod is embedded in the top of the drive box, and the telescopic end of the hydraulic rod extends into the interior of the drive box and is fixedly mounted with a rack. A gear plate is fixedly mounted inside the drive box on the support shaft, and the rack meshes with the gear plate. By setting up the inclined discharge assembly, the rack is moved by the telescopic movement of the hydraulic rod. Based on the meshing of the rack and the gear plate, the support shaft can be rotated, thereby achieving the effect of driving the screen cylinder and the material pipe to tilt downwards, which facilitates the discharge of the inoculum from the inside of the screen cylinder through the material pipe.

[0013] Furthermore, the surface of the mounting frame is welded with reinforcing ribs; by setting reinforcing ribs, the structural strength of the mounting frame can be improved, thereby improving the stability of the overall device.

[0014] Furthermore, a control panel is fixedly mounted on the front of the mounting bracket, and the control panel is electrically connected to an external power source via wires.

[0015] Beneficial Effects: Compared with existing technologies, the pre-wetting device of this invention places the inoculum inside the sieve cylinder and uses a geared motor to drive the sieve cylinder to rotate. Water is sprayed onto the surface of the inoculum through the inlet pipe, the central pipe, and the outlet hole. Because the inoculum rotates continuously with the sieve cylinder, the pre-wetting position can be constantly adjusted to ensure the effectiveness of the pre-wetting. After pre-wetting, the geared motor drives the sieve cylinder to rotate at high speed. Under centrifugal force, the water can quickly separate from the inoculum through the sieve holes and then be discharged from the drain pipe, thus achieving rapid draining of the inoculum after pre-wetting and improving the efficiency of the pre-wetting operation. By setting up a feed pipe, keeping the feed pipe opening upwards allows for the addition of the inoculum to the sieve cylinder, while keeping the feed pipe opening downwards allows for the removal of the inoculum from the sieve. The purpose of removing the contents from inside the cylinder is as follows: By setting up a stirring rod, during the rotation of the screen cylinder driven by the geared motor, the stirring rod remains stationary with the central tube, and relative movement occurs between the inoculum, the stirring rod, and the shovel plate. This allows the inoculum to be agitated using the stirring rod and the shovel plate, ensuring the uniformity of pre-wetting during the pre-wetting stage. The shovel plate also helps prevent clogging of the screen holes. By setting up an input connector and a rotating jacket, the input connector can be connected to an external water supply pipe, enabling continuous water supply to the inlet pipe. By setting up an inclined discharge assembly, the hydraulic rod extends and retracts to drive the rack to move. Based on the meshing of the rack and the toothed disc, the support shaft can be rotated, thereby achieving the effect of driving the screen cylinder and the material pipe to tilt downwards, facilitating the discharge of the inoculum from inside the screen cylinder through the material pipe.

[0026] The surface of mounting bracket 1 is welded with reinforcing ribs 23.

[0027] In this embodiment, by setting the reinforcing rib 23, the structural strength of the mounting frame 1 can be improved, thereby improving the stability of the overall device.

[0028] Two support shafts 2 are symmetrically arranged at the upper end of the mounting frame 1. A processing cylinder 3 is fixedly installed at one end of the two support shafts 2 that is close to each other. A screen cylinder 4 is rotatably connected to the inner wall of the processing cylinder 3 through a sealed bearing.

Valves are provided on the surface of both the material pipe 12 and the drain pipe 13, and the outlet end of the drain pipe 13 is connected to an external water pipe.

[0030] By setting the material pipe 12, keeping the opening of the material pipe 12 facing upwards allows the inoculum to be added to the sieve cylinder 4, while keeping the opening of the material pipe 12 facing downwards allows the inoculum to be removed from inside the sieve cylinder 4.

[0031] A pre-wetting component is provided at the right end of the treatment cylinder 3 corresponding to the screen cylinder 4, and a centrifugal dewatering component is provided at the left end of the treatment cylinder 3 corresponding to the screen cylinder 4.

The input connector 18 is connected to the rotating sleeve 17, the connecting cavity 16 and the water inlet end of the water inlet pipe 8 in sequence.

[0034] It is worth noting that, referring to Figure 5 By setting an input connector 18 and a rotating sleeve 17, the input connector 18 can be connected to an external water supply pipe, thereby enabling continuous water supply to the inlet pipe 8.

[0035] The centrifugal dewatering assembly includes a second fixed frame 10 fixedly installed at the left end of the processing cylinder 3. A reduction motor 11 is fixedly installed on the left side of the second fixed frame 10, and the output end of the reduction motor 11 is fixed to the left end of the screen cylinder 4.

[0036] It is worth noting that, referring to Figure 1 , Figure 3 and Figure 4 When the whole device is in use, the inoculum is placed inside the screen cylinder 4, and the screen cylinder 4 is driven to rotate by the geared motor 11. Water is sprayed onto the surface of the inoculum through the water inlet pipe 8, the central pipe 7 and the water outlet 9. As the inoculum rotates continuously with the screen cylinder 4, the pre-wetting position can be continuously adjusted to ensure the pre-wetting effect of the inoculum. After the pre-wetting treatment is completed, the screen cylinder 4 can be driven to rotate at high speed by the geared motor 11. Under the action of centrifugal force, the water can quickly separate from the inoculum through the screen holes 5 and then be discharged from the drain pipe 13, thereby achieving the effect of rapid draining after pre-wetting of the inoculum and improving the efficiency of the inoculum pre-wetting operation.

Furthermore, the shovel plate 15 can prevent the screen holes 5 from becoming blocked.

[0039] The support shaft 2 is rotatably connected to the mounting frame 1, and an inclined discharge assembly is provided between the mounting frame 1 and the support shaft 2.
