[0002] As a major food and cash crop in my country, the quality of post-harvest storage of potatoes directly affects economic benefits. Traditional potato storage methods often involve open-air stacking or simple warehouses, which present the following problems: First, uneven ventilation leads to heat and moisture buildup during potato stacking, which, if not dissipated in time, can cause sprouting and rotting. Second, manual turning of the potatoes is labor-intensive, inefficient, and can easily damage the potato skin. Third, impurities and debris tend to accumulate at the bottom of the storage area, blocking ventilation channels and further increasing the risk of rotting. Fourth, existing turning equipment is mostly of a fixed structure and cannot adaptively adjust the turning depth according to the height of the potato stack, resulting in poor applicability.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0028] To achieve automatic pile turning, as one embodiment of the present invention, such as Figures 1 to 6 As shown, the potato storage equipment with automatic turning and ventilation according to the present invention includes a storage bin 1 with an open top, a truss 2 above the storage bin 1, a transverse rolling mechanism installed at both ends of the truss 2, and rails 3 for supporting the rolling mechanism installed on both sides of the top of the storage bin 1. A movable frame 4 is rotatably connected to the truss 2, and a dual-axis motor 5 for driving the movable frame 4 is installed on the top of the movable frame 4. A turning structure is installed on the side of the movable frame 4, and the turning structure is driven by the dual-axis motor 5 through a transmission box 6.
[0029] In use, potatoes can be piled in storage bin 1. The rolling mechanism can drive the truss 2 to move along the track 3, thereby adjusting the position of the truss 2. After being driven by the dual-axis motor 5, the moving frame 4 can be driven to roll on the truss 2, thereby adjusting the position of the turning structure. The dual-axis motor 5 transmits power to the turning structure through the transmission box 6 to turn the potatoes. When the moving frame 4 carries the turning structure along the preset track, the turning structure continuously loosens and turns the potatoes piled in storage bin 1, breaking the compacted state of the potatoes.
[0030] To ensure ventilation at the bottom of storage compartment 1, in one embodiment of the present invention, a partition 7 is installed at the bottom of storage compartment 1. Ventilation holes are evenly distributed on the partition 7. A rotating roller 8 is located below the partition 7, directly below the turning structure. Rubber brush strips 9 are distributed circumferentially on the rotating roller 8. Support seats 10 are rotatably connected to both ends of the roller shaft of the rotating roller 8. A slide seat 11 is connected to the end of the support seat 10 away from the rotating roller 8. A horizontal groove 12 is provided on the inner wall of storage compartment 1, which is slidably connected to the slide seat 11. The roller shaft of the rotating roller 8 passes through the support seat 10 and is coaxially connected to a moving gear 13. An installation groove 14 parallel to the groove 12 is opened on the inner wall of storage compartment 1. A rack 15, meshing with the moving gear 13, is installed on the upper inner side of the installation groove 14. When the rotating roller 8 rolls along the bottom of the partition 7, the rubber brush strips 9 are inserted one by one into the ventilation holes of the partition 7, and the rubber brush strips 9 roll to clean the bottom of storage compartment 1.
[0031] In use, while the rolling mechanism drives the truss 2 to move, it also drives the support seat 10 to move. The stability of the support seat 10's movement is ensured by the cooperation of the slide seat 11 and the slide groove 12. At the same time, when the roller moves in the mounting groove 14, it can drive the rotating roller 8 to rotate by the meshing transmission of the rack 15 and the moving gear 13, thereby driving the rotating roller 8 to roll at the bottom of the partition 7.
[0032] As the rotating roller 8 moves, when the rubber brush strip 9 rotates to the position corresponding to the ventilation hole of the partition 7, the rubber brush strip 9 inserts into the ventilation hole one by one. By inserting the rubber brush strip 9 into the ventilation hole, impurities (such as potato scraps, soil particles, etc.) in the ventilation hole can be removed. At the same time, during the rolling movement of the rotating roller 8, the rubber brush strip 9 contacts the bottom of the storage bin 1, which can continuously sweep away the impurities deposited at the bottom of the storage bin 1, thereby cleaning the ventilation hole and the bottom of the storage bin 1.
[0033] To facilitate the movement of the rotating roller 8, in one embodiment of the present invention, steel cables 16 are connected to both sides of the rolling mechanism, first guide wheels 17 are installed at the ends of the track 3, and second guide wheels 18 along the direction of the slide groove 12 are installed on both sides of the storage bin 1. The steel cables 16 pass through the first guide wheels 17 and the second guide wheels 18 in sequence, enter the storage bin 1, extend along the direction of the slide groove 12, and are connected to the slide block 11.
[0034] In use, the truss 2 is driven to move laterally along the track 3 by the rolling mechanism, and the steel cable 16 can pull the slide 11 to move in the slide groove 12, thereby pulling the support 10 to move. The stability of the movement of the support 10 can be ensured by the cooperation between the slide 11 and the slide groove 12. At the same time, when the roller moves in the mounting groove 14, it can drive the rotating roller 8 to rotate by the meshing transmission of the rack 15 and the moving gear 13, thereby driving the rotating roller 8 to roll at the bottom of the partition 7.
[0035] When the rotating roller 8 moves, the rubber brush strip 9 rotates to the position corresponding to the vent hole of the partition 7. The rubber brush strip 9 is inserted into the vent hole one by one. The insertion of the rubber brush strip 9 into the vent hole can remove the impurities in the vent hole. At the same time, during the rolling movement of the rotating roller 8, the rubber brush strip 9 contacts the bottom of the storage chamber 1 and can continuously sweep away the impurities deposited at the bottom of the storage chamber 1, thereby cleaning the vent hole and the bottom of the storage chamber 1.
[0036] Preferably, the two sides of the support base 10 are connected to the inner wall of the storage compartment 1 through the first folding airbag 19 and the second folding airbag 20, respectively. The first folding airbag 19 and the second folding airbag 20 are both connected to a one-way air inlet connector. The rotating roller 8 is provided with a first air blowing plate 21 and a second air blowing plate 22 on the side of the rotating roller 8 near the first folding airbag 19 and the side of the rotating roller 8 near the second folding airbag 20, respectively. The two ends of the first air blowing plate 21 and the second air blowing plate 22 are fixedly connected to the support base 10. The first air blowing plate 21 is connected to the second folding airbag 20 through a pipe with a pressure relief valve, and the second air blowing plate 22 is connected to the first folding airbag 19 through a pipe with a pressure relief valve.
[0037] In use, the dual-axis motor 5 drives the moving frame 4 to move along the truss 2. The truss 2 slides along the track 3 through the rolling mechanism. Simultaneously, the steel cable 16 pulls the slide block 11 to move along the slide groove 12, thereby driving the support seat 10 and the rotating roller 8 to move horizontally along the bottom of the storage bin 1.
[0038] During the movement of the support base 10, when it moves to one side, it compresses the first folded airbag 19 or the second folded airbag 20 on the corresponding side. For example, when the support base 10 moves to the side of the first folded airbag 19, it compresses the first folded airbag 19 to release air and stretches the second folded airbag 20 to draw in air. The compressed first folded airbag 19 supplies air to the second blower plate 22 through the pipe. The second blower plate 22 blows air into the storage compartment 1. At this time, the blowing position of the second blower plate 22 is the area where the turning structure has just completed turning. After the turning structure moves along the truss 2 to complete the turning work of one area, the rolling mechanism drives the truss 2 to move towards the first folded airbag 19 and to the next area. At this time, the support base 10 is simultaneously pulled to the next area, and the second blower plate 22 corresponds to the area where the turning work was previously completed. At this time, the air blower plate 22 can accurately correspond to the area where the turning work was just completed, thereby improving the ventilation efficiency for loose potato piles.
[0039] Conversely, when the support base 10 moves toward the second folded airbag 20, it compresses the second folded airbag 20 to release air and stretches the first folded airbag 19 to draw in air. The compressed second folded airbag 20 supplies air to the first blower plate 21 through the pipe. The first blower plate 21 blows airflow into the storage compartment 1. Similarly, at this time, the blowing position of the first blower plate 21 is the area where the turning structure has just completed turning. Specifically, after the turning structure moves along the truss 2 to complete the turning work of one area, the rolling mechanism drives the truss 2 to move toward the second folded airbag 20 and to the next area. At this time, the support base 10 is simultaneously pulled to the next area, and the first blower plate 21 corresponds to the area where the turning work was previously completed. At this time, the air outlet of the first blower plate 21 can accurately correspond to the area where the turning work was just completed, thereby improving the ventilation efficiency for loose potato piles.
[0040] During the translation of the rotating roller 8, the rubber brush strip 9 is inserted into the ventilation hole to clean impurities. Then, the first air blowing plate 21 or the second air blowing plate 22 continuously blows airflow into the storage bin 1 and the bottom to achieve simultaneous impurity cleaning during turning and ventilation after cleaning.
[0041] It should be noted that the one-way air intake connector ensures that the first folding airbag 19 and the second folding airbag 20 can draw in air when stretched, while the pressure relief valve ensures that the first folding airbag 19 and the second folding airbag 20 can exhaust air when compressed.
[0042] To ensure the stability of the movement of the movable frame 4, in one embodiment of the present invention, the movable frame 4 is a U-shaped frame with the opening facing downwards. Several sets of horizontally arranged support rollers 23 are rotatably connected to the upper inner side of the U-shaped frame. The support rollers 23 are in rolling contact with the top of the truss 2. Auxiliary rollers 24 are installed on both sides of the U-shaped frame. The auxiliary rollers 24 are in rolling contact with the sides of the truss 2. One set of support rollers 23 is coaxially connected to a driven pulley 25 at its end. The output end of the dual-axis motor 5 is connected to a drive pulley 26 that drives the driven pulley 25.
[0043] In use, the output of the dual-axis motor 5 drives the drive pulley 26 to rotate. The drive pulley 26 drives the driven pulley 25 to rotate synchronously through the transmission belt, which in turn drives the support roller 23, which is coaxially connected to the driven pulley 25, to rotate. As one set of support rollers 23 rotates, all support rollers 23 roll along the top of the truss 2, while the auxiliary roller 24 rolls in contact with the side of the truss 2. The auxiliary support roller 23 guides the U-shaped frame to move stably along the truss 2. Under the rolling driving force of the support roller 23 and the guiding action of the auxiliary roller 24, the U-shaped frame moves linearly along the truss 2. During the movement, the support roller 23 continuously maintains rolling contact with the top of the truss 2, and the auxiliary roller 24 continuously maintains rolling contact with the side of the truss 2, ensuring the stability of the moving frame 4.
[0044] To ensure the transmission effect of the transmission box 6, as an embodiment of the present invention, a vertical support shaft 27 is rotatably connected inside the transmission box 6. A first friction transmission disk 28 and a second friction transmission disk 29 are arranged from top to bottom on the support shaft 27. The first friction transmission disk 28 and the second friction transmission disk 29 are both connected to the support shaft 27 through one-way bearings. A friction transmission wheel 30 is provided between the first friction transmission disk 28 and the second friction transmission disk 29. The lower surface of the first friction transmission disk 28 and the upper surface of the second friction transmission disk 29 are both in friction transmission with the friction transmission wheel 30. A spline shaft 31 is fixedly connected to the side of the friction transmission wheel 30 near the dual-axis motor 5. A spline sleeve 32 is slidably connected to the spline shaft 31. The spline sleeve 32 passes through the transmission box 6 and is rotatably connected to the transmission box 6. The spline sleeve 32 is connected to the output end of the dual-axis motor 5.
[0045] The top end of the support shaft 27 is coaxially connected to the drive gear 33, and the turning structure meshes with the drive gear 33 for transmission.
[0046] In use, the dual-axis motor 5 drives the spline sleeve 32 to rotate, and the spline sleeve 32 rotates synchronously, driving the spline shaft 31 and the friction transmission wheel 30 to rotate.
[0047] When the friction drive wheel 30 rotates, since it is located between the first friction drive disc 28 and the second friction drive disc 29, the first and second friction drive discs 28 and 29 rotate due to friction, and their directions of rotation are opposite. If the friction drive wheel 30 rotates forward, the first friction drive disc 28 rotates forward and the second friction drive disc 29 rotates in reverse. The first friction drive disc 28 drives the support shaft 27 to rotate forward through its own connected one-way bearing. If the friction drive wheel 30 rotates in reverse, the first friction drive disc 28 rotates in reverse and the second friction drive disc 29 rotates forward. The second friction drive disc 29 drives the support shaft 27 to rotate forward through its own connected one-way bearing. In this way, whether the friction drive wheel 30 rotates forward or in reverse, it can be ensured that the support shaft 27 rotates stably only in the positive direction, while the other set of one-way bearings that do not transmit power are in an idle state, without interfering with the power transmission.
[0048] If it is necessary to adjust the rotational speed of the support shaft 27, the spline shaft 31 can be controlled to slide along the axial direction of the spline sleeve 32, thereby driving the friction transmission wheel 30 to translate between the lower surface of the first friction transmission disk 28 and the upper surface of the second friction transmission disk 29, changing the contact radius of the friction transmission wheel 30. When the support shaft 27 needs to operate at a lower speed, the friction transmission wheel 30 is moved towards the edge area of the first friction transmission disk 28 or the edge area of the second friction transmission disk 29 to increase the contact radius and thus reduce the rotational speed of the support shaft 27. When the support shaft 27 needs to operate at a higher speed, the friction transmission wheel 30 is moved towards the center area of the first friction transmission disk 28 or the center area of the second friction transmission disk 29 to decrease the contact radius and thus increase the rotational speed of the support shaft 27.
[0049] The drive gear 33 rotates synchronously with the support shaft 27, and the drive gear 33 drives the turning structure to rotate forward at the corresponding speed, realizing potato turning operations at different speeds. During the operation, the axial position of the spline shaft 31 can be adjusted according to the real-time turning requirements, dynamically changing the contact radius between the friction transmission wheel 30 and the first friction transmission disc 28 and the second friction transmission disc 29, flexibly adjusting the speed of the support shaft 27 to adapt to the dynamic changes in the potato stacking state during storage. At the same time, during the entire speed adjustment process, the two sets of one-way bearings always ensure that the support shaft 27 does not reverse, maintaining the continuity and stability of the turning operation.
[0050] To ensure the turning effect of the turning structure, as an embodiment of the present invention, the turning structure includes a rotating shaft 34 and a rubber spiral plate 35 connected to the rotating shaft 34. The upper end of the rotating shaft 34 passes through the transmission box 6 and is slidably connected to the transmission box 6. A support ring 36 is rotatably connected to the rotating shaft 34. A support spring 37 is connected between the support ring 36 and the inner wall of the transmission box 6. A driven gear 38 that meshes with the drive gear 33 is connected to the top of the rotating shaft 34. A first hydraulic telescopic rod 39 is fixedly connected between the lower part of the support ring 36 and the inner wall of the transmission box 6.
[0051] A positioning ring 40 is rotatably connected to the splined shaft 31. A compression spring 41 is connected between the positioning ring 40 and the splined sleeve 32. A second hydraulic telescopic rod 42 is provided between the positioning ring 40 and the inner wall of the transmission box 6. The first hydraulic telescopic rod 39 and the second hydraulic telescopic rod 42 are connected through a pipeline. The second hydraulic telescopic rod 42 is fixedly connected to the inner wall of the transmission box 6. A ball bearing is installed at the output end of the second hydraulic telescopic rod 42, and the ball bearing makes rolling contact with the positioning ring 40.
[0052] When in use, the dual-shaft motor 5 is started, and the power is transmitted to the friction transmission wheel 30 through the spline sleeve 32 and spline shaft 31. The friction transmission wheel 30 drives the corresponding friction transmission disc to rotate, and then transmits the power to the driven gear 38 through the one-way bearing, support shaft 27 and drive gear 33. The driven gear 38 drives the rotating shaft 34 and rubber spiral plate 35 to rotate, and the rubber spiral plate 35 performs the turning operation on the potatoes.
[0053] During the turning process, if the local potato pile is higher, the resistance to the rubber spiral plate 35 is greater, and the downward force on the rubber spiral plate 35 when it rotates is greater. This force is transmitted to the support ring 36 through the rotating shaft 34, further compressing the first hydraulic telescopic rod 39. After the first hydraulic telescopic rod 39 is compressed, the hydraulic oil pressure in the pipeline increases, pushing the second hydraulic telescopic rod 42 to extend further. The second hydraulic telescopic rod 42 pushes the positioning ring 40 to continue moving towards the support shaft 27 through the ball bearings, and the compression spring 41 is further extended. The positioning ring 40 drives the spline shaft 31 and the friction transmission wheel 30 to generate a larger displacement along the axial direction of the spline sleeve 32.
[0054] When the displacement of the friction drive wheel 30 increases, the contact radius between the friction drive wheel 30 and the first friction drive disc 28 and the second friction drive disc 29 decreases, and the rotation speed of the support shaft 27 increases accordingly. In turn, the rotation speed of the rotating shaft 34 and the rubber spiral plate 35 increases synchronously through the drive gear 33 and the driven gear 38, so as to quickly turn the pile at a higher speed, overcome the resistance of the piled potatoes, and ensure the turning effect.
[0055] As the potato pile height decreases, the resistance to the rubber spiral plate 35 decreases. The first hydraulic telescopic rod 39 extends under the restoring force of the support spring 37, and the hydraulic oil in the pipeline flows back. The second hydraulic telescopic rod 42 retracts under the restoring force of the compression spring 41. The positioning ring 40 drives the spline shaft 31 and the friction transmission wheel 30 to move in the opposite direction, increasing the contact radius. The rotation speed of the support shaft 27 and the rubber spiral plate 35 decreases, which is suitable for the low-resistance turning requirements. The ball bearings maintain rolling contact with the positioning ring 40, reducing frictional resistance during the adjustment process and ensuring smooth linkage adjustment.
[0056] To facilitate cleaning of the bottom of storage compartment 1, as an embodiment of the present invention, slag discharge ports are provided on both sides of the bottom of storage compartment 1, and sealing doors 43 are detachably connected to the slag discharge ports.
[0057] When in use, the sealing door 43 should be kept in a detachable closed state to prevent external dust, impurities or pests from entering the storage chamber 1 through the slag discharge port, thus ensuring the cleanliness of the potato storage environment.
[0058] During the turning operation, the impurities cleaned by the rubber brush strip 9 inserted into the ventilation hole of the partition 7, as well as the impurities that fall directly through the ventilation hole, will fall to the bottom of the storage bin 1 under the action of gravity. As the rotating roller 8 rolls and moves, the rubber brush strip 9 gradually cleans the impurities at the bottom of the storage bin 1 and accumulates them near the slag discharge port.
[0059] When impurities accumulate to a certain amount at the bottom of storage bin 1, or after a round of large-scale turning operations is completed, the equipment can be stopped, the detachable connection between the sealing door 43 and the slag discharge port can be released, and the sealing door 43 can be removed. After the sealing door 43 is removed, impurities near the slag discharge port can be removed manually. After the impurities are cleaned, the sealing door 43 can be reinstalled on the slag discharge port, and the detachable connection between the sealing door 43 and the slag discharge port can be restored to ensure that the sealing door 43 is tightly closed. Then the equipment can be restarted to continue storage operations such as turning and ventilation.
[0060] To facilitate the movement of the rolling mechanism, as an embodiment of the present invention, the rolling mechanism includes a bracket 44 connected to both sides of the end of the truss 2, and an electric roller 45 is installed inside the bracket 44. The electric roller 45 is rotatably connected to the track 3.
[0061] When in use, the electric roller 45 starts to rotate after being powered on, driving the bracket 44 and truss 2 to move linearly along the track 3. During the movement of the truss 2, the moving frame 4, drive motor, transmission box 6, turning structure and other components move synchronously along the track 3 to adjust the turning operation area. When the truss 2 moves to the target operation area, the electric roller 45 can be controlled to stop rotating. When the electric roller 45 is stationary, it forms a stable support with the track 3, keeping the truss 2 and related components in the target position, which is convenient for carrying out fixed-point turning and ventilation operations. After the turning structure moves along the direction of the truss 2 to complete the turning, the electric roller 45 can be controlled to continue to operate, moving the turning structure to the next turning area to achieve comprehensive turning of potatoes in the storage bin 1 and avoid dead corners in the operation.
[0062] When the present invention is in use, after the dual-axis motor 5 is started, the driven pulley 26 and the transmission belt drive the driven pulley 25 and the support roller 23 to rotate. With the cooperation of the support roller 23 and the auxiliary roller 24, the moving frame 4 moves stably along the truss 2.
[0063] One output end of the dual-axis motor 5 drives the friction transmission wheel 30 to rotate through the spline sleeve 32 and spline shaft 31. The friction transmission wheel 30 drives the first friction transmission disc 28 and the second friction transmission disc 29 through friction. The power is transmitted to the rotating shaft 34 through the one-way bearing, support shaft 27, drive gear 33 and driven gear 38. The rubber spiral plate 35 rotates at high speed to loosen and turn the potatoes, breaking up the piled and compacted state.
[0064] If potatoes pile up too high in a local area, the rubber spiral plate 35 will experience increased downward resistance, which will push the first hydraulic telescopic rod 39 to compress. This will then cause the second hydraulic telescopic rod 42 to extend through the hydraulic pipeline, driving the friction transmission wheel 30 to move towards the center area and increasing the turning speed. When the resistance decreases, the speed will automatically decrease to ensure the turning effect and equipment stability.
[0065] When the truss 2 moves along the track 3 via the rolling mechanism, the support seat 10 is driven by the steel cable 16 to move synchronously along the slide 12, squeezing the corresponding folded airbag to one side (such as squeezing out air when moving towards the first folded airbag 19, and stretching the second folded airbag 20 to inhale air).
[0066] The compressed folded airbags supply air to the corresponding blower plates through pipes equipped with pressure relief valves (airbag 19 is compressed to supply air to the second blower plate 22, and the second folded airbag 20 is compressed to supply air to the first blower plate 21). The blower plates precisely target the loose area that has just been turned over, blowing airflow and significantly improving ventilation efficiency.
[0067] When the support base 10 moves horizontally, the roller shaft meshes with the rack 15 in the mounting groove 14 through the moving gear 13, driving the rotating roller 8 to rotate synchronously. The rubber brush strips 9 rotate with the rotating roller 8 and are inserted into the ventilation holes of the partition plate 7 one by one to remove potato scraps, soil particles and other impurities in the holes.
[0068] During the rotation of the rotating roller 8, the rubber brush strip 9 continuously sweeps across the bottom of the storage bin 1, pushing the deposited impurities toward the slag discharge port; the synchronous ventilation airflow assists the impurities to fall, avoiding secondary blockage of the ventilator.
[0069] When the impurities at the bottom of storage chamber 1 accumulate to a certain amount or after a full round of operation is completed, turn off the power to the equipment, disconnect the detachable connection of the slag discharge port sealing door 43, and manually remove the accumulated impurities; after cleaning, reinstall the sealing door 43 to ensure a tight closure.
