Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of manure treatment, and in particular to a paving device and an air drying system. Background Art

[0002] Livestock and poultry manure contains a wealth of nutrients, and proper treatment can transform waste into valuable resources. Common manure treatment methods include composting and fermentation, as well as drying the manure into dry manure for use as fertilizer in the fields.

[0003] Livestock farms produce a large amount of manure every day, but the drying cycle of manure generally takes 5 to 7 days, during which time the weather needs to be clear and the manure needs to be turned over frequently. Therefore, drying manure requires manpower, time and space, none of which can be missing.

[0004] For most farms, freeing up manpower or using a tiller to turn the manure can solve the problems of both labor and time. However, the size of the site occupied is directly determined by the amount of manure. When the amount of manure is large, spreading the manure on the ground will not only solidify the use of the land, but also require space for turning by manpower or a tiller, which brings inconvenience to the farm land. Summary of the Invention

[0045] The embodiment of the present application provides a spreading device that can make the space occupied by the air drying of manure flexible and reduce the inconvenience caused by the land use of the farm. The spreading device provided in the embodiment of the present application can be used to air dry manure, fruits and vegetables, cloth and other items with moisture.

[0046] Figure 1 This is a structural diagram of a paving device provided in an embodiment of the present application. Figure 2 This is a partial enlarged view of the paving device provided in the embodiment of the present application. Figure 1 and Figure 2 As shown, the paving device 1 provided in an embodiment of the present application includes a paving plate 11 and a connecting member 12. The surface of the paving plate 11 has a plurality of ventilation holes 13, and a first fixing structure 14 is provided at both ends of the paving plate 11. The paving plate 11 is used to place material 0. The connecting member 12 includes a second fixing structure 15. The first fixing structure 14 and the second fixing structure 15 are fixedly connected to secure the paving plate 11 to the connecting member 12.

[0047] Optionally, the paving board 11 can be a straight board with a plurality of ventilation holes 13, and the ventilation holes 13 run through the upper and lower surfaces of the straight board. Specifically, the plurality of ventilation holes 13 can be regularly arranged or staggered. Figure 1 and Figure 2 As shown, the ventilation holes 13 of the paving board 11 are staggered in rows, which can reduce stress distribution on the one hand, and on the other hand, allow all the wind to pass through the ventilation holes 13 to dry the material 0, without ignoring each row of material 0, avoiding the situation where the wind passing through the gap between two rows is wasted, thereby improving the drying effect. The shape of the ventilation holes 13 can be circular, square, regular or irregular, and this application does not limit the shape of the ventilation holes 13. Figure 2 As shown, the shape of the ventilation hole 13 can be a rounded rectangle with complete semicircles at both ends.

[0048] Specifically, the material 0 to be air-dried is placed on the paving board 11. The size of the ventilation holes 13 on the paving board 11 is adapted to the type of material 0. The material 0 can be placed on the paving board 11 without leaking through the ventilation holes 13. During the air-drying process, air contacts the material 0 from above, below, and around it. The flowing air blows over the surface of the material 0, which can accelerate the drying of the material 0.

[0049] Optionally, the air blown toward the material 0 can have a certain temperature, forming warm air or hot air. Warm air or hot air blown toward the material 0 further accelerates the drying of the material 0. In addition, the paving plate 11 can be a metal plate with good heat transfer performance, so that it is heated by the heated air. When the hot air does not directly flow over the surface of the material 0, heat can be transferred to the material 0 through the heated paving plate 11, causing the water vapor in the material 0 to evaporate faster, thereby drying the material 0 faster.

[0050] Optionally, the second fixing structure 15 can be connected to the first fixing structures 14 at both ends of a paving board 11, thereby supporting the paving board 11 through the connecting member 12. The side of the second fixing structure 15 of the connecting member 12 close to the ground is at a distance from the ground, thereby raising the paving board 11 and allowing air to pass under the paving board 11, forming an airflow to carry away moisture from the material 0.

[0051] Alternatively, the first fixing structure 14 may be at least two fixing holes at one end of the paving board 11, and the second fixing structure 15 may be a fixing plate including at least two fixing posts corresponding to the positions and sizes of the fixing holes. Alternatively, the first fixing structure 14 may be at least two fixing posts at one end of the paving board 11, and the second fixing structure 15 may be a fixing plate including at least two fixing holes corresponding to the positions and sizes of the fixing holes.

[0052] Optionally, Figure 3 This is a schematic diagram of the structure of two connectors provided in the embodiment of this application. Figure 3As shown, the connecting member 12 may be a first connecting member 121 including one second fixing structure 15 , or a second connecting member 122 including two second fixing structures 15 distributed on both sides.

[0053] Specifically, the paving boards 11 can be fixedly connected at their short sides by the second connector 122, thereby expanding the paving area along the length direction 31 of the paving boards 11. The paving boards 11 can also be fixedly connected at their long sides by the first connector 121, thereby expanding the paving area along the width direction 32 of the paving boards 11. In addition, adjacent first connectors 121 or second connectors 122 can be fixed to each other, thereby expanding the paving area in both the length direction 31 and the width direction 32.

[0054] For example, Figure 4 This is another structural diagram of the paving device provided in the embodiment of the present application. Figure 4 As shown, the paving board 11a and the paving board 11b are fixedly connected along the length direction 31 of the paving board 11 by the second connecting member 122, widening the width of the paving device 1, and the paving board 11a and the paving board 11d, and the paving board 11b and the paving board 11c are fixedly connected along the width direction 32 of the paving board 11 by the first connecting member 121, widening the length of the paving device 1, and the paving board 11d and the paving board 11c are fixedly connected by the second fixing member, so that the paving boards 11abcd can be fixedly connected to form a large paving board 11 of 2 blocks × 2 blocks. It can be seen from this that the paving board 11 can be freely expanded into a large paving board 11 of x blocks × y blocks by the first connecting member 121 and / or the second connecting member 122, so that the paving board 11 can be flexibly arranged in the length and / or width direction 32 according to the amount of air-dried material and the land conditions, so as to expand the paving area in accordance with the actual situation.

[0055] By providing the ventilation holes 13, there is more contact area between the material 0 and the air. The paving board 11 is fixed to the connecting piece 12, and the connecting piece 12 can be used to set up the paving board 11, so that air can flow from the bottom of the paving board 11, thereby accelerating the drying of the material 0. The ventilation holes 13 are staggered, so that the air flowing through the paving board 11 passes through the ventilation holes 13, and the drying effect of the flowing air on the material 0 is not wasted. In addition, through the mutual cooperation between the first fixed structure 14 and the second fixed structure 15, the paving area can be arbitrarily expanded in the length direction 31 and / or width direction 32 of the paving board 11, so that it can form various shapes such as a field shape, an L shape, and a + shape, which are suitable for different ground conditions.

[0056] In some embodiments, the paving board 11 is integrally formed, and both long sides of the paving board 11 are bent 90 degrees in the same direction.

[0057] For example, Figure 2As shown, the long sides of the paving board 11 are bent in the same direction. In actual use, the bent sides can be directed toward the ground. Thus, when the paving board 11 is placed on a flat surface, the lower surface of the paving board 11 is ensured not to come into contact with an object and is in an air-free state, thereby allowing air to flow through the upper and lower surfaces of the paving board 11 to accelerate the drying of the material 0. When the paving board 11 is supported by the connecting member 12, more support can be provided at multiple positions, thereby being able to place more types and weights of materials 0, thereby increasing the bearing capacity of the paving board 11.

[0058] In addition, the paving board 11 is manufactured using an integrated molding and bending process, which can further increase the load-bearing capacity of the paving board 11, so that the long sides on both sides provide a supporting force opposite to the weight of the material 0, thereby increasing the supporting strength of the paving board 11.

[0059] In some embodiments, the connecting member 12 includes a linking member 16 . The linking member 16 is fixedly connected to the second fixing structure 15 , and the linking member 16 can roll on a plane.

[0060] Specifically, two adjacent connecting members 12 are fixed to each other via an axis connection, and the connecting member 16 can be a sphere or ellipsoid that is connected in a rolling manner around the fixed axis 162. The connecting member 16 is fixedly connected to the second fixed structure 15, and is thereby fixedly connected to the paving board 11. The rolling portion of the connecting member 16 exceeds the height of the paving board 11, and the paving board 11 is driven to roll on the plane through the connecting member 16, thereby moving the paving board 11 and the material 0 on the paving board 11 through thrust, thereby facilitating the movement of the paving board 11.

[0061] In some embodiments, the linkage member 16 includes a rolling member 161 and a fixed shaft 162 , and the rolling member 161 is axially connected and fixed to the fixed shaft 162 .

[0062] Specifically, the rolling member 161 can be a sphere or ellipsoid with a through hole, and its cross section in the length direction 31 is a circle. The fixed shaft 162 passes through the through hole, and both ends of the fixed shaft 162 are respectively fixed to the connecting member 12, thereby fixing the rolling member 161 to the connecting member 12 and allowing it to roll around the fixed shaft 162, thereby rolling on a plane and driving the paving board 11 to move.

[0063] In some embodiments, the linkage member 16 is a linkage shaft with a circular cross section, wherein the diameter of the linkage shaft at the rolling zone is larger than the diameters at both ends of the linkage shaft, and the rolling zone is located in the middle of the linkage shaft in the shaft length direction 31 .

[0064] Specifically, the shaft length direction 31 can be the length direction 31 of the material 0 plate. At this time, when the connecting member 16 rolls, the material 0 plate moves in the width direction 32. Correspondingly, the shaft length direction 31 can be the width direction 32 of the material 0 plate. At this time, when the connecting member 16 rolls, the material 0 plate moves in the length direction 31.

[0065] Alternatively, the linkage 16 may be an integral structure, with the middle protruding portion being a rolling area and the two ends being fixed areas, the rolling area having a diameter larger than the fixed area and protruding from the connector 12. The fixed areas at both ends are fixed to the connector 12, and the rolling areas roll, driving the connector 12 and the paving board 11 fixed to the connector 12 to move.

[0066] Alternatively, as Figure 4 As shown, in some embodiments, when the length of the paving board 11 is greater than or equal to a length threshold, at least one set of first fixing structures 14 is provided between the two ends of the paving board 11 and fixedly connected to the connecting member 12 .

[0067] Specifically, the length threshold can be determined based on the material, length, width, and thickness of the paving board 11. When the length of the paving board 11 is long, or the material 0 placed thereon is heavy, the connecting member 12 can be fixed by setting a first fixing structure 14 in the middle, so that the connecting member 12 provides support in the middle of the material 0 board, increases the supporting force of the middle position of the paving board 11 on the material 0, and avoids deformation of the paving board 11.

[0068] For example, when the length of the paving board 11 is greater than or equal to the length threshold, a first fixing structure 14 may be provided between the two ends of the paving board 11 along the length direction 31, and the first fixing structure 14 of the paving board 11 and the second fixing structure 15 of the connecting member 12 are fixed, thereby fixing the connecting member 12 between the two ends of the paving board 11. For example, Figure 4 As shown, a set of first fixing structures 14 are provided in the central region of the paving board 11 along the length direction 31, which are respectively fixedly connected to the second fixing structures 15 of the connecting member 12, thereby enhancing the fixing and supporting effects and driving the movement of the paving board 11. The central region of the paving board 11 along the length direction 31 can be a straight plate without ventilation holes 13, to prevent the material 0 from leaking from the ventilation holes 13 to the linkage 16 of the connecting member 12, thereby affecting the movement effect.

[0069] In some embodiments, the paving device 1 may further include a motor 17 and a polygonal gear 18 , the polygonal gear 18 is engaged with the connecting piece 12 , and multiple paving boards 11 , connecting pieces 12 and polygonal gears 18 constitute a transmission layer 19 , and the motor 17 drives the transmission layer 19 for transmission.

[0070] For example, Figure 5 This is a schematic diagram of the structure of the transport layer provided in the embodiment of the present application. Figure 5As shown, multiple paving boards 11 are fixedly connected by a first connecting member 121 and a second connecting member 122 to form a conveyor layer 19 having a structure similar to a conveyor belt. Polygonal gears 18 are located at both ends of the conveying layer 19. Motors 17 are connected to the polygonal gears 18 to control the rotation of the polygonal gears 18. The paving boards 11 located at both ends of the conveying layer 19 are always engaged with the polygonal gears 18. When the motor 17 controls the rotation of the polygonal gears 18, the paving boards 11 are driven by the polygonal gears 18 and rotate at the same speed as the motor 17, thereby realizing the transmission of the paving boards 11.

[0071] In some embodiments, there are multiple transmission layers 19 , which are spaced apart in the vertical direction 33 , and the starting end of the lower transmission layer 19 in two adjacent layers protrudes beyond the tail end of the higher transmission layer 19 in the horizontal direction 34 .

[0072] Specifically, the starting end of the conveying layer 19 can be understood as the feed end of the conveying layer 19, and the material 0 is laid from the feed end to the conveying layer 19. The tail end of the conveying layer 19 can be understood as the discharge end of the conveying layer 19, and the material 0 is sent out of the conveying layer 19 from the discharge end.

[0073] For example, Figure 6 This is a multi-layer distribution diagram of the paving device provided in the embodiment of the present application. Figure 6 As shown, multiple conveying layers 19 can be spaced apart in the vertical direction 33, with the beginning of each layer protruding from the end of the previous layer from top to bottom, to receive the material 0 that naturally falls from the previous conveying layer 19 during conveying. For example, the beginning of the second layer protrudes from the end of the first layer, allowing the material 0 to fall from the end of the first layer to the beginning of the second layer, where it is transported to the end by the second conveying layer 19. Then, the material 0 is caught by the beginning of the third conveying layer 19, which protrudes from the end of the second layer, and so on, continuing to be transported. By staggering the multiple conveying layers 19, it is possible to ensure that the material 0 is transported from top to bottom between the multiple conveying layers 19 while significantly saving floor space.

[0074] Based on the above embodiment, the embodiment of the present application also provides an air-drying system 20. Figure 7 This is a structural diagram of an air drying system provided in an embodiment of the present application. Figure 7 As shown, the air-drying system 20 provided in an embodiment of the present application includes an air-drying room and a spreading device 1 according to any of the above embodiments. The spreading device 1 is located in the air-drying room 202 of the air-drying room, and at least one axial flow fan 203 is provided between the air-drying unit 201 and the air-drying room 202. The air direction of the axial flow fan 203 is from the air-drying unit 201 toward the air-drying room 202.

[0075] By setting an axial flow fan 203 between the drying unit 201 and the drying chamber 202, the air in the drying unit 201 can always be blown to the laying device 1 in the drying chamber 202, so that the air in the drying system 20 circulates and dries the material 0.

[0076] Optionally, the drying unit 201 may include a heating device to increase the temperature of the air in the drying unit 201, thereby causing the airflow from the axial flow fan 203 to the drying chamber 202 to be hot air, accelerating the drying of the material 0. Furthermore, the temperature in the drying chamber 202 is maintained at a high temperature, so that the material 0 is dried by the high-temperature air in the drying chamber 202. Drying and air-drying are performed simultaneously to ensure efficient drying of the manure.

[0077] In some embodiments, the paving device 1 is at least one layer of paving boards 11 , each layer of paving boards 11 corresponds to at least one axial flow fan 203 , and the axial flow fan 203 is located below the paving boards 11 .

[0078] Specifically, such as Figure 7 As shown, the multiple layers of the paving boards 11 can be distributed in the vertical direction, thereby saving floor space. The axial flow fan 203 is arranged below the paving boards 11, so that the hot air flow blown by the axial flow fan 203 passes through the lower surface of the material 0, removing moisture, and the hot air flow will spontaneously move upward, thereby filling the entire air drying chamber 202, further drying the material 0.

[0079] Alternatively, as Figure 5 and Figure 6 As shown, in some embodiments, the paving device 1 includes multiple staggered conveying layers 19, and each conveying layer 19 is composed of multiple paving boards 11, connectors 12, a motor 17, and a hexagonal gear. The motor 17 drives the conveying layer 19 to convey the material 0, and transports the material 0 from top to bottom to the discharge port of the lowest layer. During the process, the material 0 is accelerated to dry through the air-drying room and the axial flow fan 203. At this time, the transmission speed of the conveying layer 19 controlled by the motor 17 to transport the material 0 can be determined according to the transportation distance and time of the material 0 from the feed port to the discharge port, and the transportation time can be determined by the air-drying speed of the air-drying room, thereby realizing full-process automated control of the air-drying process, reducing human intervention, and reducing odor leakage.

[0080] The air-drying system 20 provided in the embodiment of the present application, by setting a spreading device 1 in a closed air-drying room and blowing air to the spreading device 1 through an axial flow fan 203, can make the air flow always pass through the material 0, thereby taking away the moisture in the material 0, accelerating the drying of the material 0, and effectively improving the air-drying efficiency of the manure.

[0081] In summary, the paving device 1 and the air-drying system 20 provided in the embodiment of the present application provide more contact area between the material 0 and the air by setting the ventilation holes 13. The paving plate 11 is fixed to the connecting member 12, and the connecting member 12 can be used to set up the paving plate 11 so that air can circulate from the bottom of the paving plate 11, thereby accelerating the drying of the material 0. The ventilation holes 13 are staggered, so that the air flowing through the paving plate 11 can pass through the ventilation holes 13, without wasting the drying effect of the flowing air on the material 0. In addition, through the mutual cooperation between the first fixed structure 14 and the second fixed structure 15, the paving area can be arbitrarily expanded in the length direction 31 and / or width direction 32 of the paving plate 11, so that it can form various shapes such as a field shape, an L shape, and a + shape, which are suitable for different ground conditions. By arranging the paving device 1 in a closed air-drying room and blowing air to the paving device 1 through the axial flow fan 203, the air flow can always pass through the material 0, thereby taking away the moisture in the material 0, accelerating the drying of the material 0, and effectively improving the drying efficiency of the manure.
