Description

Technical Field

[0001] This utility model belongs to the field of mushroom drying technology, specifically relating to a turning device for drying mushroom slices. Background Technology

[0002] In the processing of shiitake mushrooms, freshly sliced ​​mushrooms have a high water content. To reduce the energy consumption of the dryer, retain the nutrients of the mushrooms, and enhance their flavor, sun-drying is a crucial step that directly affects the quality of the mushrooms and the subsequent processing results. The traditional method of sun-drying shiitake mushrooms involves spreading the sliced ​​mushrooms flat on a mesh drying frame, gradually turning the fresh mushrooms into dried ones. This process requires manual turning of each mushroom slice on the drying frame, which is labor-intensive, inefficient, and consumes a lot of manpower and time, while also increasing the processing cost. Therefore, to solve these problems, it is necessary to design a drying frame turning device for sun-drying shiitake mushroom slices. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a turning device for drying frames of shiitake mushroom slices. A turning frame for detachably fixing drying frames one and two is rotatably mounted on a movable frame. A telescopic cylinder located on the outer wall of the movable frame is connected to a rotating shaft on the corresponding outer wall of the turning frame via a turning positioning and locking device. This allows the telescopic cylinder to control the locked and unlocked rotational states of the turning frame, thereby completing the assembly and disassembly of drying frames one and two on the turning frame, and the operation of turning the shiitake mushroom slices from drying frame one onto drying frame two. This solves the problems of high labor intensity and low efficiency associated with manual turning. Mechanized turning replaces manual turning, reducing manual operation, lowering worker labor intensity, and allowing for rapid completion of the turning process. Compared to manual turning, it significantly saves time and improves the overall efficiency of shiitake mushroom slice drying. Reducing manpower and time consumption directly lowers labor and time costs in the shiitake mushroom processing process. During the turning process, the shiitake mushroom slices are spread evenly, avoiding problems such as stacking and omissions that may occur when turning them manually, ensuring consistent drying results and improving product quality.

[0004] The technical solution adopted in this utility model is as follows: a turning device for drying shiitake mushroom slices, including a movable frame and a turning frame located inside the upper end of the movable frame. A rotating shaft is fixed to the middle of the outer wall at both ends of the turning frame, and the outer end of the rotating shaft extends out of the movable frame and is rotatably mounted on the corresponding side wall panel of the movable frame. A first drying frame containing shiitake mushroom slices and a second drying frame covering the first drying frame are detachably fixed to the turning frame. Support frames are provided on the outer walls of both sides of the movable frame, and a telescopic cylinder fixed to the upper surface of the support frame is connected to the rotating shaft through a turning positioning and locking device. When the telescopic cylinder drives the moving part of the turning positioning and locking device to move inward to match the locking position of the rotating shaft, the rotating shaft is locked in the initial working position. Alternatively, when the telescopic cylinder drives the moving part of the turning positioning and locking device to move outward to separate from the locking position of the rotating shaft, the rotating shaft is unlocked, and the shiitake mushroom slices on the first drying frame are turned over and spread on the second drying frame by rotating the turning frame.

[0005] The flipping positioning and locking device includes a moving plate and a locking sleeve. The piston rod end of the telescopic cylinder is fixedly connected to the outer end face of the moving plate, and the locking sleeve is fixed to the inner end face of the moving plate. The inner hole of the locking sleeve consists of a hexagonal hole in the right half and a guide hole in the left half that is concentric with the hexagonal hole. An arc-shaped positioning groove is formed on the lower wall of the guide hole. A hexagonal shaft section is formed on the outside of the moving frame and is adapted to the hexagonal hole. A positioning protrusion is formed on the outer wall of the rotating shaft, which is adapted to the locking sleeve. When the flipping frame rotates to the point where the positioning protrusion contacts the upper wall of the arc-shaped positioning groove, the piston rod of the telescopic cylinder drives the locking sleeve to move inward until the hexagonal hole and the hexagonal shaft section are adapted to achieve the horizontal positioning of the flipping frame. When the piston rod of the telescopic cylinder drives the locking sleeve to move outward until the hexagonal hole and the hexagonal shaft section are separated, the flipping frame is rotated by ° to flip the mushroom slices on the drying frame one and spread them on the drying frame two.

[0006] Furthermore, a guide rail is fixed to the upper end face of the support frame, and a slider adapted to the guide rail is adapted to and fixed to the bottom of the locking sleeve.

[0007] Furthermore, threaded holes are made at the four corners of the upper surface of the flip frame, and through holes corresponding to the threaded holes are made at the four corners of both the first and second drying frames. The first and second drying frames are detachably fixed to the flip frame by hand-tightened bolts that pass through the through holes and are adapted to the threaded holes at the corresponding positions on the flip frame.

[0008] Furthermore, the rotating shaft is rotatably mounted on the movable frame via bearings.

[0009] Furthermore, the frame plate of the flipping frame is evenly distributed with several ventilation holes.

[0010] Advantages of this utility model compared to the prior art:

[0011] 1. This technical solution involves rotating and installing a flipping frame on a mobile frame for detachably fixing drying frames one and two. A telescopic cylinder located on the outer wall of the mobile frame is connected to a rotating shaft on the corresponding outer wall of the flipping frame via a flipping positioning and locking device. This allows the telescopic cylinder to control the locked mounting state and unlocked rotation state of the flipping frame through the flipping positioning and locking device, thereby completing the assembly and disassembly of drying frames one and two on the flipping frame and the operation of flipping the mushroom slices on drying frame one onto drying frame two. This solves the problem of high labor intensity and low efficiency associated with manual flipping.

[0012] 2. The flipping positioning and locking device in this technical solution features a structure that adapts to a hexagonal hole and a hexagonal shaft segment. When the hexagonal hole and the hexagonal shaft segment are adapted, the flipping frame can be stably positioned in the horizontal drying or loading position, ensuring that the flipping frame will not rotate arbitrarily during the drying or loading process, thus guaranteeing the stability of the mushroom slices during drying and loading. When the locking sleeve moves outward to separate the hexagonal hole and the hexagonal shaft segment, the flipping frame can rotate 180°, providing the rotation operation conditions for the mushroom slices on drying frame one to be flipped and spread on drying frame two.

[0013] 3. The flipping positioning and locking device in this technical solution has a structure in which a positioning protrusion and an arc-shaped positioning groove are matched, which can assist in the positioning during the flipping process, so that the mushroom slices on the first drying frame are accurately flipped and spread on the second drying frame. At the same time, it provides reset positioning conditions for the smooth and reliable cooperation between the hexagonal hole and the hexagonal shaft section in the locked state.

[0014] 4. This technical solution adopts a guide rail on the upper end face of the support frame, and the slider fixed to the bottom of the locking sleeve is adapted to the guide rail to provide guidance and support for the movement of the locking sleeve. This ensures that the locking sleeve can move stably and smoothly along a fixed direction under the drive of the telescopic cylinder, avoids the locking sleeve from deviating or jamming during the movement, and ensures the matching accuracy with the rotating shaft.

[0015] 5. This technical solution uses mechanized flipping to replace manual flipping of each mushroom slice, reducing manual labor and the intensity of labor for workers. The flipping process can be completed quickly, saving a significant amount of time compared to manual flipping, improving the overall efficiency of mushroom slice drying, reducing labor input and time consumption, and directly reducing labor and time costs in the mushroom processing process. During the flipping process, the mushroom slices are spread evenly, avoiding problems such as stacking and omissions that may occur when manually flipping, ensuring consistent drying results for mushroom slices and improving product quality.

[0021] A turning device for drying frames used for drying shiitake mushroom slices, such as Figure 1As shown, the device includes a movable frame 1 and a flip frame 2 located inside the upper part of the movable frame 1. A rotating shaft 3 is fixed to the middle of the outer wall at both ends of the flip frame 2, and the rotating shaft 3 extends out of the movable frame 1 and is rotatably mounted on the corresponding side wall panel of the movable frame 1. Specifically, the rotating shaft 3 is rotatably mounted on the movable frame 1 via a bearing 11. A drying frame 6 containing mushroom slices and a second drying frame 7 covering the drying frame 6 are detachably fixed to the flip frame 2. Supports are provided on the outer walls of the side wall panels of the movable frame 1. The support frame 4 and the telescopic cylinder 5 fixed to the upper end face of the support frame 4 are connected to the rotating shaft 3 through the flip positioning and locking device. When the telescopic cylinder 5 drives the moving part of the flip positioning and locking device to move inward to match the locking position of the rotating shaft 3, the rotating shaft 3 in the initial working position is locked. Alternatively, the telescopic cylinder 5 drives the moving part of the flip positioning and locking device to move outward to separate from the locking position of the rotating shaft 3, so that after the rotating shaft 3 is unlocked, the mushroom slices on the drying frame 1 6 are flipped over and spread on the drying frame 2 7 by rotating the flip frame 2.

[0022] In the above structure, a flipping frame 2 for detachably fixing drying frame 6 and drying frame 7 is rotatably installed on the mobile frame 1, and a telescopic cylinder 5 located on the outer wall of the mobile frame 1 is connected to the rotating shaft 3 on the corresponding outer wall of the flipping frame 2 through a flipping positioning and locking device. The telescopic cylinder 5 controls the locking and unlocking rotation state of the flipping frame 2 through the flipping positioning and locking device, thereby completing the disassembly and assembly of drying frame 6 and drying frame 7 on the flipping frame 2 and the operation of flipping and spreading the mushroom slices on drying frame 6 onto drying frame 7. This solves the problem of high labor intensity and low efficiency of manual flipping.

[0023] like Figure 1-2As shown, the flipping positioning and locking device includes a moving plate 8 and a locking sleeve 9. The piston rod end of the telescopic cylinder 5 is fixedly connected to the outer end face of the moving plate 8, and the locking sleeve 9 is fixed to the inner end face of the moving plate 8. The inner hole of the locking sleeve 9 is composed of a hexagonal hole 9-1 in the right half and a guide hole 9-2 in the left half, which is concentrically arranged with the hexagonal hole 9-1. An arc-shaped positioning groove 9-3 is formed on the lower wall of the guide hole 9-2. A hexagonal shaft section 3-1 is formed on the rotating shaft 3, located outside the moving frame 1 and adapted to the hexagonal hole 9-1. A positioning protrusion 3-2 is formed on the outer wall of the rotating shaft 3, located outside the hexagonal shaft section 3-1. The rotating shaft 3 is adapted to the... Inside the locking sleeve 9, when the flipping frame 2 rotates until the positioning protrusion 3-2 contacts the upper groove wall on one side of the arc-shaped positioning groove 9-3, the piston rod of the telescopic cylinder 5 drives the locking sleeve 9 to move inward until the hexagonal hole 9-1 matches the hexagonal shaft section 3-1, thereby positioning the flipping frame 2 in a horizontal position. When the piston rod of the telescopic cylinder 5 drives the locking sleeve 9 to move outward until the hexagonal hole 9-1 separates from the hexagonal shaft section 3-1, the flipping frame 2 is rotated 180° to flip the mushroom slices on the drying frame 1 6 and place them on the drying frame 2 7. Specifically, the upper end face of the support frame 4 is fixed with a guide rail 12, and the slider 13 adapted to the guide rail is adapted to and fixedly connected to the bottom of the locking sleeve 9.

[0024] In the above structure, the flipping positioning and locking device is equipped with a structure that adapts to the hexagonal hole 9-1 and the hexagonal shaft section 3-1. This allows the flipping frame 2 to be stably positioned in the horizontal drying or loading position when the hexagonal hole 9-1 and the hexagonal shaft section 3-1 are adapted, ensuring that the flipping frame will not rotate arbitrarily during drying or loading, thus guaranteeing the stability of the mushroom slices during drying and loading. When the locking sleeve 9 moves outward, separating the hexagonal hole 9-1 from the hexagonal shaft section 3-1, the positioning protrusion 3-2 and the arc-shaped positioning groove 9- With the positioning of 3, the flipping frame 2 can rotate 180°, providing the rotation operation conditions for the mushroom slices on the drying frame 6 to be flipped and spread on the drying frame 7; the flipping positioning locking device, by setting the positioning protrusion 3-2 and the arc positioning groove 9-3 to cooperate, can assist the positioning during the flipping process, so that the mushroom slices on the drying frame 6 can be accurately flipped and spread on the drying frame 7, and at the same time provide the reset positioning conditions for the smooth and reliable cooperation of the hexagonal hole 9-1 and the hexagonal shaft section 3-1 in the locked state;

[0025] A guide rail 12 is provided on the upper end face of the support frame 4, and the slider 13 fixed to the bottom of the locking sleeve 9 is adapted to the guide rail 12 to provide guidance and support for the movement of the locking sleeve 9. This ensures that the locking sleeve 9 can move stably and smoothly along a fixed direction under the drive of the telescopic cylinder 5, avoiding the locking sleeve 9 from deviating or jamming during the movement, and ensuring the matching accuracy with the rotating shaft 3. The telescopic cylinder 5 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0026] The detachable fastening structure of drying frames 6 and 7 on the flip frame 2 is as follows: Threaded holes are formed at the four corners of the upper surface of the flip frame 2, and through holes corresponding to the threaded holes are formed at the four corners of both drying frames 6 and 7. Drying frames 6 and 7 are detachably fixed to the flip frame 2 by hand-tightening bolts 10 that pass through the through holes and are fitted with the corresponding threaded holes on the flip frame 2. In this structure, the hand-tightening bolts 10 with symmetrically distributed threaded holes at the four corners and matching through holes ensure that drying frames 6 and 7 will not shift, fall off, or shake during the 180° rotation of the flip frame 2, preventing mushroom slices from falling or piling up due to loosening of drying frames 6 and 7, thus ensuring stability during the flipping process. The detachable design of the hand-tightening bolts 10 allows for quick removal of drying frames 6 after drying or when replacement or maintenance is required. The drying frame 27 is detached from the flip frame 2 for easy subsequent operations (such as taking out and putting in mushroom slices, cleaning the drying frame, etc.), which takes into account both the firmness of the connection and the flexibility of operation.

[0027] The frame plate of the flipping frame 2 is evenly distributed with several ventilation holes. When the flipping operation is not required, the mushroom slices can be dried. When the mushroom slices are turned over, the drying frame 2 7 can be fixed to the flipping frame 2 by hand-tightening bolts 10, and the flipping operation can be completed by rotating the unlocked flipping frame 2 180°.

[0028] The specific work process is as follows:

[0029] Initial fixing state: First, with the positioning protrusion 3-2 in contact with the upper wall of the arc-shaped positioning groove 9-3, the telescopic cylinder 5 drives the locking sleeve 9 of the flip positioning locking device to move inward, so that the hexagonal hole 9-1 of the locking sleeve 9 matches the hexagonal shaft section 3-1 of the rotating shaft 3, thus completing the horizontal locking of the flip frame 2; then, there are two situations: one is to place the drying frame 6 containing shiitake mushroom slices on the upper end of the flip frame 2, and cover the drying frame 7 with the empty drying frame 6, and connect the drying frame 6 and the drying frame 7 with the threaded holes at the four corners of the two by hand-tightening bolts 10, so as to achieve the detachable fixing of the drying frame 6 and the drying frame 7 on the flip frame 2; the other is to fix the drying frame 7 to the upper end of the flip frame 2 by hand-tightening bolts 10 when the shiitake mushroom slices on the flip frame 2 are flipped over.

[0030] Unlocking and preparing to flip: When it is necessary to flip the mushroom slices, the telescopic cylinder 5 drives the locking sleeve 9 to move outward, so that the hexagonal hole 9-1 separates from the hexagonal shaft section 3-1, the rotating shaft 3 is unlocked, and the flipping frame 2 can rotate freely around the rotating shaft 3.

[0031] Flipping operation: Rotate the flipping frame 2. During the rotation, the positioning protrusion 3-2 moves within and along the arc-shaped positioning groove 9-3 to ensure a smooth flipping process. When the positioning protrusion 3-2 moves to contact the upper wall of the arc-shaped positioning groove 9-3 on the other side, the flipping frame 2 rotates 180° and stops rotating. At this time, the mushroom slices on the drying frame 1 6 are flipped over and laid on the drying frame 2 7 under the action of gravity. Disassemble the drying frame 2 7 and the drying frame 1 6, and remove the drying frame 2 7 containing the flipped mushroom slices for drying.

[0032] Relocking and Drying: After flipping, rotate the flipping frame 2 in the opposite direction so that the positioning protrusion 3-2 contacts the upper wall of the arc-shaped positioning groove 9-3. The telescopic cylinder 5 then drives the locking sleeve 9 to move inward again, so that the hexagonal hole 9-1 and the hexagonal shaft segment 3-1 are refitted, locking the flipped shaft 3. At this time, the flipping frame 2 is reset, completing one flipping operation. If flipping is required again, repeat the above unlocking, flipping, and locking steps.

[0033] This technical solution uses mechanized flipping to replace manual flipping of each mushroom slice, reducing manual labor and the intensity of labor for workers. The flipping process can be completed quickly, saving a significant amount of time compared to manual flipping, improving the overall efficiency of mushroom slice drying, reducing labor input and time consumption, and directly reducing labor and time costs in the mushroom processing process. During the flipping process, the mushroom slices are spread evenly, avoiding problems such as stacking and omissions that may occur when flipping manually, ensuring consistent drying results and improving product quality.
