[0002] Grain vinegar is made from grains through fermentation.

[0003] According to the prior art, a fermentation bed (publication number: CN221488651U) is disclosed, which includes a fermentation bed body. Slide grooves are opened on both sides of the fermentation bed body. Sliding sliders are slidably installed in both slide grooves. A turning mechanism is detachably installed between the two sliding sliders. A driving mechanism is installed on one side of the fermentation bed body.

[0004] Existing technologies mainly use displacement combined with rakes to turn over materials. The displacement resistance is high, and the corresponding power is also high. The overall rake turning method exerts a large compression force on the materials, and the materials on the fermentation bed are prone to overall displacement and overflow. Therefore, there is room for optimization in the turning method.

[0005] Therefore, we propose an automatic substrate turning device for mushroom beds. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide an automatic turning device for mushroom beds.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic mushroom bed turning device, comprising:

[0008] Two parallel tracks are provided, and a crossbeam that can slide along the radial direction of the track is provided on the track. A sliding seat perpendicular to the displacement of the track is slidably provided at the bottom of the crossbeam.

[0009] A stirring structure is installed on a sliding seat for turning materials. The stirring structure includes a stirring column, a stirring motor, side rods, and a swinging body. The stirring motor is fixedly installed on the sliding seat. The stirring column is rotatably connected to the sliding seat and fixedly connected to the output shaft of the stirring motor. Several side rods are fixedly installed on the upper end of the stirring column. A swinging body that can be rotatably installed on one side of each side rod is provided.

[0010] In a preferred embodiment of this utility model, the top of the track is provided with a guide rib, and the bottom of the crossbeam is provided with a suitable sliding groove, with the guide rib located in the sliding groove.

[0011] In a preferred embodiment of this utility model, a lead screw is rotatably provided at the bottom of both the track and the crossbeam. The crossbeam is threadedly connected to the lead screw at the top of the track, and the sliding seat is threadedly connected to the lead screw at the bottom of the crossbeam. The lead screw is driven by a motor.

[0012] In a preferred embodiment of this utility model, a guide rod is fixedly installed at the bottom of the crossbeam, and the sliding seat has a guide hole adapted to the guide rod, with the guide rod located inside the guide hole.

[0013] In a preferred embodiment of this utility model, the agitating column includes a conical body with vortex-shaped blades welded to its circumferential surface. A main shaft is fixedly installed at the upper end of the body and is fixedly connected to the output shaft of the agitating motor. A bushing is fixedly provided at the bottom of the sliding seat, and the main shaft is rotatably connected to the bushing.

[0014] In a preferred embodiment of this utility model, the side rod is formed into a rod with an L-shaped cross-section, and the side rod is distributed radially parallel to the stirring column.

[0015] In a preferred embodiment of this utility model, the swing body includes a rectangular plate and a counterweight. The counterweight is fixedly connected to one side of the rectangular plate, and the counterweight abuts against one side of the side rod. The rectangular plate is fixedly connected to the side rod by a pin.

[0016] This utility model provides an automatic mushroom bed turning device. It has the following beneficial effects:

[0017] 1. This automatic mushroom bed turning device uses a stirring motor to drive the stirring column to rotate, which, in conjunction with the two-axis displacement of the sliding seat, turns the mushroom bed through the rotation of the stirring column during the sliding seat's movement. Compared with the existing technology that uses a rake to turn the material, this solution can not only turn the material but also turn the material between the upper and lower layers, reducing dead corners in the turning process and preventing the bottom material from becoming compacted during fermentation, thus affecting the yield. The turning method of rotating the stirring column in conjunction with the two-axis displacement can reduce the probability of material overflowing from the mushroom bed.

[0018] 2. This automatic mushroom bed turning device uses a side rod that moves in a circular motion with the stirring column. The centrifugal force generated during the movement of the side rod causes the oscillating body to swing. Since the sliding seat has linear displacement, the oscillating body hits the material as the stirring column moves linearly with the sliding seat. The oscillating body, swinging to an inclined angle, works with the side rod to form a branch-like rod that strikes the material, keeping it loose. Combined with the rotation of the stirring column, this device can significantly reduce the probability of material compaction on the mushroom bed, improving the turning effect and efficiency.

[0025] An automatic substrate turning device for mushroom beds, such as Figure 1 and Figure 2 As shown, it includes:

[0026] Two parallel tracks 10 are provided, and a crossbeam 11 that can slide radially along the track 10 is provided on the track 10. A sliding seat 12 perpendicular to the displacement of the track 10 is slidably provided at the bottom of the crossbeam 11. A guide rib is provided at the top of the track 10, and a matching groove is opened at the bottom of the crossbeam 11, with the guide rib located in the groove. A lead screw 13 is rotatably provided at the bottom of both the track 10 and the crossbeam 11. The crossbeam 11 is threadedly connected to the lead screw 13 at the top of the track 10, and the sliding seat 12 is threadedly connected to the lead screw 13 at the bottom of the crossbeam 11. The sliding seat 12 is connected by a threaded connection. A nut (not shown in the figure) that mates with the lead screw 13 is fixedly installed on the sliding seat 12. The sliding seat 12 moves linearly along the crossbeam 11 through the engagement of the nut and the lead screw 13. The lead screw 13 is driven by a motor. A guide rod is fixedly installed at the bottom of the crossbeam 11. There are two guide rods that are parallel to each other and are symmetrically distributed about the lead screw as the axis. The guide rods are clearance-fitted with the guide holes. The sliding seat 12 has a guide hole adapted to the guide rods, and the guide rods are located in the guide holes.

[0027] The motor driving the lead screw 13 is a servo motor, which is connected to the controller. The lead screw 13 is fixedly connected to the output shaft of the motor. The lead screw 13 drives the crossbeam 11 to slide radially along the track 10. The other lead screw 13 drives the sliding seat 12 to slide radially along the crossbeam 11, realizing the two-axis displacement of the sliding seat 12. The movement of the sliding seat 12 can realize the uniform turning of the mushroom bed, which has high controllability and higher degree of automation.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the agitation structure, mounted on the sliding seat 12, is used for material turning. The agitation structure includes an agitation column 20, an agitation motor 21, side rods 22, and a swinging body 23. The agitation motor 21 is fixedly installed on the sliding seat 12. The agitation column 20 is rotatably connected to the sliding seat 12 and fixedly connected to the output shaft of the agitation motor 21. Several side rods 22 are fixedly installed on the upper end of the agitation column 20. Each side rod 22 has a rotatable swinging body 23 rotatably mounted on one side. The agitation column 20 includes a conical main body, and the circumference of the main body... The main body is welded with vortex-shaped blades. A main shaft is fixedly installed at the upper end of the main body. The main shaft is fixedly connected to the output shaft of the stirring motor 21. A bushing is fixedly provided at the bottom of the sliding seat 12. The main shaft is rotatably connected to the bushing. The side rod 22 forms a rod with an L-shaped cross section. The side rod 22 is distributed radially parallel to the stirring column 20. The swing body 23 includes a rectangular plate and a counterweight. The counterweight is fixedly connected to one side of the rectangular plate. The counterweight abuts against one side of the side rod 22. The rectangular plate is fixedly rotatably connected to the side rod 22 through a pin.

[0029] The guide ribs / grooves of the track 10 and crossbeam 11, the lead screw 13, the nut and the sliding surface of the sliding seat 12 are made of stainless steel (such as 304 or 316), and telescopic dust covers or accordion-style protective covers are installed on the lead screw 13 and the guide rail to prevent dust from entering.

[0030] At the rotating connection between the main shaft of the stirring column 20 and the bushing of the sliding seat 12: a lip seal ring (such as NBR rubber) is installed on the rotating shaft, and a dust cover is installed on the top of the bushing.

[0031] The pin connection of the swing body 23: a sealed pin bushing or a dust cap is installed at the end of the pin.

[0032] Stirring motor 21: Select a servo motor or three-phase asynchronous motor with an IP65 or higher protection rating, and use a waterproof cable connector at the motor junction box inlet.

[0033] All exposed surfaces of carbon steel components: coated with epoxy anti-rust paint or hot-dip galvanized.

[0034] In this scheme, the stirring column 20 is driven to rotate by the stirring motor 21, and the two-axis displacement of the sliding seat 12 is coordinated. During the displacement of the sliding seat 12, the rotation of the stirring column 20 is used to turn the material in the mushroom bed. Compared with the existing technology that uses a rake to turn the material, this scheme can not only turn the material, but also turn the material between the upper and lower layers, reduce dead corners in the turning process, and avoid the bottom material from caking and affecting the yield.

[0035] The maximum swing angle of the swing body 23 is limited by the mechanical limiting structure (such as limiting boss or limiting pin, not shown in the figure) on the counterweight and the side rod 22. The side rod 22 moves in a circular motion with the stirring column 20, and the centrifugal force generated during the movement of the side rod 22 will cause the swing body 23 to swing. In the initial state, the swing body 23 is in contact with the side rod. When the centrifugal force is greater than the gravitational component of the swing body 23, an amplitude will be generated. When the stirring column 20 stops, the swing body 23 returns to its original position under the action of gravity. Since the sliding seat 12 has linear displacement, the swing body 23 hits the material by the linear movement of the stirring column 20 with the sliding seat 12. The swing body 23, which swings to an inclined angle, works with the side rod 22 to form a branch-like rod to hit the material and keep it loose. With the rotation of the stirring column 20 to turn the material, the probability of material compaction on the mushroom bed can be greatly reduced, and the turning effect and efficiency can be improved.

[0036] The working principle of this invention is as follows: In the material turning mode, the controller controls the screw motor on the track 10 to drive the crossbeam 11 to move intermittently along the track direction (X-axis) (step distance S, e.g., 300mm). Simultaneously, the controller controls the screw motor on the crossbeam 11 to drive the sliding seat 12 to continuously reciprocate along the crossbeam direction (Y-axis) (the stroke covers the width of the mushroom bed). During the movement of the sliding seat 12, the stirring motor 21 drives the stirring column 20 to rotate at a constant speed N (e.g., 200 rpm). The insertion depth H of the stirring column 20 into the material (e.g., 300mm) is achieved by adjusting the vertical position of the entire crossbeam 11 (requiring an additional Z-axis lifting mechanism, not shown in the figure) or by setting a fixed installation height. This mode forms a grid-like material turning path.

[0037] Control parameters: Step distance S, Y-axis moving speed Vy, stirring speed N, insertion depth H, etc. can be set through the human-machine interface (HMI) according to the characteristics of the mushroom bed material and the turning requirements.

[0038] The crossbeam 11 is driven by the lead screw 13 to slide radially along the track 10, and the sliding seat 12 is driven by the other lead screw 13 to slide radially along the crossbeam 11, realizing the two-axis displacement of the sliding seat 12. The stirring column 20 is driven to rotate by the stirring motor 21. In conjunction with the two-axis displacement of the sliding seat 12, the rotating motion of the stirring column 20 during the displacement of the sliding seat 12 realizes the turning of the material in the mushroom bed. The side rod 22 moves in a circle with the stirring column 20. The centrifugal force generated during the movement of the side rod 22 will cause the oscillating body 23 to swing. Since the sliding seat 12 has linear displacement, the oscillating body 23 hits the material by the linear movement of the stirring column 20 with the sliding seat 12. The oscillating body 23, which swings to an inclined angle, cooperates with the side rod 22 to form a branch-shaped rod to hit the material and keep it loose.
