[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.
[0034] The present application provides a fruit and vegetable three-dimensional drying device, and an embodiment thereof is shown in the accompanying drawings. Figures 1 to 6 The fruit and vegetable three-dimensional drying device comprises a rack 10, a chain circulating conveying mechanism 20 arranged on the rack 10, a plurality of trays 30 circulating conveyed on the chain circulating conveying mechanism 20, and an overturning mechanism 40 arranged at the bottom of the chain circulating conveying mechanism 20. The conveying track of the chain circulating conveying mechanism 20 is arranged in a plurality of layers in a back-and-forth manner. The tray 30 is rotationally connected to the chain circulating conveying mechanism 20 in a free rotation manner, and the tray 30 is provided with an overturning gear 31 at the side of the chain circulating conveying mechanism 20. The overturning mechanism 40 is provided with a rack 41 which can be lifted. The lifting of the rack 41 is used to engage with the overturning gear 31, so that the tray 30 is overturned during movement.
[0035] In the application, the fruits and vegetables to be dried are placed on the trays 30, and then the control rack 41 is separated from the turnover gear 31, and the trays 30 can be circulated on the chain circulation conveying mechanism 20, which not only makes full use of the three-dimensional space of the drying room, but also ensures the uniformity of drying; when unloading is needed, the control rack 41 is raised, and the trays 30 pass through the meshing of the turnover gear 31 and the rack 41, so that the trays 30 are automatically turned over as they continue to move, thereby achieving the function of automatic unloading.
[0036] As shown in Figure 1 , this embodiment provides a chain circulation conveying mechanism 20 including conveying chains 21 and steering gears 22, and the steering gears 22 are meshed with the upper and lower conveying position switching positions of the conveying chains 21.
[0037] After adopting this arrangement, part of the steering gears 22 can be used as driving gears to provide driving force, and part of the steering gears 22 can be used as driven gears to rotate, thereby achieving the circulation of the conveying chains 21; and after adopting the above arrangement, the steering gears 22 can also keep the conveying chains 21 in a fully tensioned state.
[0038] As shown in Figure 1 , Figure 4 and Figure 5 , this embodiment provides a tray 30 provided with a positioning plate 32; the upper and lower conveying position switching positions of the chain circulation conveying mechanism 20 are each provided with a pressing plate 23, the position of the pressing plate 23 is arranged on the moving path of the positioning plate 32, and when the positioning plate 32 passes through the pressing plate 23, the pressing plate 23 is pressed against the positioning plate 32.
[0039] After adopting this arrangement, once the tray 30 moves to the position of the pressing plate 23, the positioning plate 32 will be placed below the pressing plate 23, and the pressing plate 23 is pressed against the positioning plate 32, thereby avoiding the swinging of the tray 30 during steering and lifting, ensuring the stability of the vegetable and fruit conveying process, and avoiding the possibility of interference due to shaking.
[0040] As shown in Figure 1 and Figure 6 , this embodiment provides a chain circulation conveying mechanism 20 provided with a pin shaft 24, and the tray 30 is provided with a shaft sleeve 33 inserted into the pin shaft 24 in a clearance fit manner, so that it can rotate freely.
[0041] After adopting this arrangement, the pin shaft 24 can be used to improve the connection stability of the tray 30 and the chain circulation conveying mechanism 20, and the tray 30 can be kept in a large turning position under the action of gravity.
[0042] As shown in Figure 1 , this embodiment is provided with a plurality of supporting strips 51 at the bottom of each layer of the conveying path of the chain circulation conveying mechanism 20, which are arranged adjacent to the bottom of the plurality of trays 30 to prevent the plurality of trays 30 from shaking greatly during the conveying process.
[0043] After adopting this arrangement, the supporting strips 51 can reduce the lower space of the trays 30, so that the trays 30 cannot be turned to dump the fruits and vegetables, thereby providing better guarantee for the stable conveying of the fruits and vegetables.
[0044] As shown in Figure 1 and Figure 3 , this embodiment of the three-dimensional fruit and vegetable drying device further comprises a stabilizing mechanism 60, which is provided with a liftable supporting strip 61 arranged in the area where the trays 30 are turned over, and the upper position of the liftable supporting strip 61 is arranged adjacent to the bottom of the plurality of trays 30 to prevent the plurality of trays 30 from shaking greatly during the conveying process.
[0045] When the trays 30 do not need to be turned over and unloaded, the trays 30 are prone to shake in the area where the trays 30 are turned over and unloaded, and after adopting the above arrangement, the liftable supporting strip 61 can be lifted when the trays 30 do not need to be turned over and unloaded to prevent the trays 30 from shaking greatly, thereby further ensuring the stability of the conveying of the fruits and vegetables.
[0046] As shown in Figures 1 to 3 , this embodiment of the stabilizing mechanism 60 further comprises a stabilizing base 62, a stabilizing lifting rod 63 vertically arranged on the stabilizing base 62, a stabilizing guide shaft 64 movably connected with the stabilizing base 62, and a stabilizing guide shaft sleeve 65 sleeved on the stabilizing guide shaft 64; the telescopic end of the stabilizing lifting rod 63 and the top of the stabilizing guide shaft 64 are connected with the liftable supporting strip 61; and the stabilizing lifting rod 63 of the stabilizing mechanism 60 is linked with the liftable rack 41 of the turning mechanism 40, so that when the liftable rack 41 is lowered and disengaged from the gear, the stabilizing lifting rod 63 is raised to play a stabilizing role; when the liftable rack 41 is raised and engaged with the gear, the stabilizing lifting rod 63 is lowered to prevent interference with the trays 30.
[0047] After adopting this arrangement, the telescopic lifting of the stabilizing lifting rod 63 can realize the lifting control of the liftable supporting strip 61, and the mutual cooperation of the stabilizing guide column and the stabilizing guide shaft sleeve 65 can realize the stable lifting control of the liftable supporting strip 61.
[0048] As shown in Figure 2As shown, a position detection switch 42 is provided on the rack 41. The position detection switch 42 is used to detect the meshing state of the rack 41 and the flipping gear 31. During the flipping process of the tray 30, the fruit and vegetable three-dimensional drying device is used to control the rack 41 to mesh with the flipping gear 31 according to the detection result of the position detection switch 42, and keep the lifting support bar 61 away from the tray 30. During the cyclic conveying process of the tray 30, the fruit and vegetable three-dimensional drying device is used to control the rack 41 to separate from the flipping gear 31 according to the detection result of the position detection switch 42, and keep the lifting support bar 61 adjacent to the tray 30.
[0049] Preferably, when the fruit and vegetable three-dimensional drying device adjusts according to the detection result of the position detection switch 42, the fruit and vegetable three-dimensional drying device can control the lifting support bar 61 and the rack 41 to rise and fall by means of a delayed preset time.
[0050] The specific control process at this time is as follows:
[0051] like Figure 7 As shown, when the drying device needs to unload, the position detection switch 42 detects whether the tilting gear 31 of the tray 30 is above the rack 41. If it is, the tray 30 continues to move forward, and the detection is repeated. If it is not, the tray 30 is controlled to stop moving, and the detection is repeated to see if the tilting gear 31 is above the rack 41. If it is, the tray 30 is controlled to move and continue moving forward, and the detection is repeated. If it is still not, the rack 41 of the tilting mechanism 40 rises, the tilting gear 31 of the tray 30 meshes with the rack 41, and then the tray 30 is controlled to move, and the tray 30 tilts to unload the material. In addition, before the tray 30 moves, the control system also needs to determine whether the rack 41 has risen for more than a preset delay time of 10 seconds. If it has not exceeded this time, the tray 30 cannot be controlled to move. This prevents the rack 41 and the lifting support bar 61 from not being fully in place, which would cause the tray 30 to fail to tilt exactly 360° and cause interference.
[0052] like Figure 8 As shown, when it is necessary to stop the tilting tray 30, the position detection switch 42 detects that the tilting gear 31 of the tray 30 is above the rack 41. If it is above, the tray 30 continues to move forward, and the detection is repeated; if it is not above, the control system stops the movement of the tray 30, and the detection is repeated to see if the tilting gear 31 is above the rack 41. If it is above, the control system moves the tray 30 and continues to move forward, and the detection is repeated; if it is still not above, the rack 41 of the tilting mechanism 40 descends, and the tilting gear 31 of the tray 30 disengages from the rack 41. In addition, before controlling the tray 30 to move, the control system also needs to determine whether the descent of the rack 41 exceeds the preset delay time of 10 seconds. If it does not exceed the time limit, the control system cannot control the movement of the tray 30, which can prevent the rack 41 and the lifting support bar 61 from not being fully in place, and thus prevent the tray 30 from interfering with the lifting support bar 61 and the impact support bar 52.
[0053] As shown in Figure 1 , this embodiment provides an impact strip 52 on the lowermost conveying path of the chain loop conveying mechanism 20, the surface of the impact strip 52 is covered with soft rubber, the impact strip 52 is arranged in the area after the tray 30 moves away from the turnover mechanism 40, and the impact strip 52 is arranged adjacent to the bottom of the plurality of trays 30 to prevent the plurality of trays 30 from overturning during conveying.
[0054] After the tray 30 is overturned, the impact strip 52 will be impacted due to inertia, and the soft rubber covering the impact strip 52 can be used to achieve buffering to prevent noise and impact force.
[0055] As shown in Figure 1 and Figure 2 , this embodiment provides a turnover mechanism 40 including a turnover lifting seat 43 provided with a rack 41 at the top, a turnover base 44 arranged below the turnover lifting seat 43, a turnover lifting rod 45 arranged vertically on the turnover base 44, a turnover guide shaft 46 connected with the turnover base 44 in a vertically movable manner, and a turnover guide shaft sleeve 47 sleeved on the turnover guide shaft 46; and the extension end of the turnover lifting rod 45 and the top of the turnover guide shaft 46 are connected with the turnover lifting seat 43.
[0056] After adopting this arrangement, the extension and retraction of the turnover lifting rod 45 can achieve lifting control of the rack 41, and the cooperation of the turnover guide column and the turnover guide shaft sleeve 47 can achieve stable lifting control of the rack 41.
[0057] As shown in Figure 1 and Figure 3 , this embodiment provides a fruit and vegetable three-dimensional drying device further including a conveying belt 70 arranged below the area where the tray 30 is turned over.
[0058] After adopting this arrangement, the conveying belt 70 can be used to receive the falling fruits and vegetables, avoiding the fruits and vegetables from falling to the ground.
[0059] The above describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements are also considered within the protection scope of the present application.
