TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of excrement treatment, in particular to a material spreading device and a drying system. BACKGROUND

[0002] Livestock manure contains a large amount of nutrients, and proper treatment can turn waste into treasure. In addition to composting and fermentation, manure can be dried into dry manure as fertilizer for field use.

[0003] Livestock farms produce a large amount of manure every day, but the drying period of manure generally needs 5 to 7 days, and it needs sunny weather and frequent turning during the period. Therefore, artificial, time and space are indispensable for drying manure.

[0004] For most farms, freeing up manpower or using a turning machine to turn can solve the problems of manpower and time at the same time, but the size of the occupied space is directly determined by the amount of manure. In the case of large amount of manure, the manure is spread on the ground, which not only solidifies the use of land, but also needs space for manual or turning machine turning, which brings inconvenience to the use of land of the farm. SUMMARY

[0005] In view of the above problems, the embodiment of the present application provides a material spreading device and a drying system, which can make the land occupation of manure drying flexible and reduce the inconvenience of the use of land of the farm.

[0006] According to a first aspect of the embodiment of the present application, a material spreading device is provided, which comprises a material spreading plate, the surface of the material spreading plate has a plurality of ventilation holes, the two ends of the material spreading plate are provided with a first fixing structure, and the material spreading plate is used for placing materials; A connecting piece is provided, which comprises a second fixing structure; the first fixing structure and the second fixing structure are fixedly connected, and the material spreading plate is fixed on the connecting piece.

[0007] In some embodiments, the material spreading plate is integrally formed, and the two side long edges of the material spreading plate are bent by 90 degrees in the same direction.

[0008] In some embodiments, the connecting piece comprises a linkage, the linkage is fixedly connected with the second fixing structure, and the linkage can roll in a plane.

[0009] In some embodiments, the linkage comprises a rolling piece and a fixed shaft, and the rolling piece is fixedly connected with the fixed shaft.

[0010] In some embodiments, the linkage is a linkage shaft with a circular cross section; the diameter of the linkage shaft at a rolling area is greater than the diameters of the two ends of the linkage shaft; and the rolling area is located in the middle of the linkage shaft in the length direction of the shaft.

[0011] In some embodiments, when the length of the material spreading plate is greater than or equal to the first threshold, at least one set of first fixing structures is provided at the middle of both ends of the material spreading plate and fixedly connected to the connector.

[0012] In some embodiments, the material spreading device further includes a motor and a polygonal gear, the polygonal gear meshing with a connector, and multiple material spreading plates, connectors and polygonal gears forming a conveying layer, with the motor driving the conveying layer for transmission.

[0013] In some embodiments, there are multiple transport layers; According to a second aspect of the embodiments of this application, a drying system is provided, including a drying chamber and a material spreading device as described in any of the first aspects; the material spreading device is located in the drying chamber of the drying chamber, and at least one axial flow fan is provided between the drying unit and the drying chamber, the airflow direction of the axial flow fan being the direction from the drying unit toward the drying chamber.

[0014] In some embodiments, the material spreading device is at least one layer of spreading plate, each layer of spreading plate corresponds to at least one axial flow fan, and the axial flow fan is located below the spreading plate.

[0015] This embodiment of the application, by incorporating ventilation holes, increases the contact area between the material and the air.

The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the material spreading device and drying system of this application. For example, in the description of this application, the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the descriptions of directions such as the x-direction, y-direction, and z-direction used to explain the operation and construction of the components of the spreading device and drying system in this embodiment are not absolute but relative. Although these directions are appropriate when the components of the spreading device and drying system are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

[0033] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] This application provides a material spreading device that allows for flexible space allocation in the drying of manure and reduces inconvenience to farm land. The material spreading device provided in this application can be used to dry manure, fruits and vegetables, cloth, and other items that have moisture.

[0037] Figure 1 This is a schematic diagram of a material spreading device provided in an embodiment of this application. Figure 2 This is a partially enlarged view of the material spreading device provided in an embodiment of this application. For example... Figure 1 and Figure 2 As shown, the material spreading device 1 provided in this embodiment includes a spreading plate 11 and a connector 12. The spreading plate 11 has multiple ventilation holes 13 on its surface, and first fixing structures 14 are provided at both ends of the spreading plate 11. The spreading plate 11 is used to place material 0. The connector 12 includes a second fixing structure 15. The first fixing structure 14 and the second fixing structure 15 are fixedly connected, fixing the spreading plate 11 to the connector 12.

[0038] Optionally, the material spreading plate 11 can be a straight plate with multiple ventilation holes 13, the ventilation holes 13 penetrating the upper and lower surfaces of the straight plate. Specifically, the multiple ventilation holes 13 can be arranged regularly or staggered. For example... Figure 1 and Figure 2As shown, the ventilation holes 13 of the material spreading plate 11 are staggered in rows. This reduces stress distribution and ensures that all airflow passes through the ventilation holes 13 to dry the material 0, without neglecting any row of material 0. This avoids wasting airflow passing between rows, thus improving the drying effect. The shape of the ventilation holes 13 can be circular, square, regular, or irregular; 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.

[0039] Specifically, the material 0 to be air-dried is placed on the spreading plate 11. The size of the ventilation holes 13 on the spreading plate 11 is adapted to the type of material 0, so that the material 0 can be placed on the spreading plate 11 without leaking through the ventilation holes 13. During the air-drying process, air comes into contact with the material 0 from above, below and all around, and the flowing air blows across the surface of the material 0, which can accelerate the air-drying of the material 0.

[0040] Optionally, the air blown toward the material 0 can be heated to form warm or hot air. The warm or hot air further accelerates the drying process of the material 0. Additionally, the spreading plate 11 can be a metal plate with good heat transfer properties, allowing it to be heated by the warm air. This allows heat to be transferred to the material 0 through the heated spreading plate 11 even when the hot air does not flow directly over its surface, enabling faster evaporation of moisture and quicker drying of the material 0.

[0041] Optionally, the second fixing structure 15 can be connected to the first fixing structures 14 located at both ends of a material spreading plate 11, thereby supporting the material spreading plate 11 through the connector 12. The side of the second fixing structure 15 of the connector 12 that is close to the ground is at a distance from the ground, thereby raising the material spreading plate 11 so that air can pass under the material spreading plate 11 to form an airflow that carries away the moisture of the material 0.

[0042] Optionally, the first fixing structure 14 may be at least two fixing holes located at one end of the spreading plate 11, and the second fixing structure 15 may be a fixing plate including at least two fixing posts corresponding to the position and size of the fixing holes. Alternatively, the first fixing structure 14 may be at least two fixing posts located at one end of the spreading plate 11, and the second fixing structure 15 may be a fixing plate including at least two fixing holes corresponding to the position and size of the fixing holes.

[0043] Optionally, Figure 3 These are schematic diagrams illustrating the structures of two types of connectors provided in embodiments of this application. For example... Figure 3 As shown, the connector 12 can be a first connector 121 including a second fixing structure 15, or a second connector 122 including two second fixing structures 15 distributed on both sides.

[0044] Specifically, the two spreading plates 11 can be fixedly connected by the short sides of the two spreading plates 11 through the second connector 122, thereby expanding the spreading area along the length direction 31 of the spreading plates 11. The two spreading plates 11 can also be fixedly connected by the long sides of the two spreading plates 11 through the first connector 121, thereby expanding the spreading area along the width direction 32 of the spreading plates 11. In addition, adjacent first connectors 121 or second connectors 122 can be fixed to each other, thereby expanding the spreading area in both the length direction 31 and the width direction 32.

[0045] For example, Figure 4 This is another structural schematic diagram of the material spreading device provided in the embodiments of this application. For example... Figure 4 As shown, spreading plates 11a and 11b are fixedly connected along the length direction 31 of spreading plate 11 by a second connector 122, widening the width of spreading device 1. Spreading plates 11a and 11d, and spreading plates 11b and 11c are fixedly connected along the width direction 32 of spreading plate 11 by a first connector 121, widening the length of spreading device 1. Spreading plates 11d and 11c are fixedly connected by a second fastener, thus the spreading plates 11abcd can be fixedly connected into a large spreading plate 11 of 2 × 2. Therefore, by means of the first connector 121 and / or the second connector 122, the spreading plate 11 can be freely expanded into a large spreading plate 11 of x × y, so that the spreading plates 11 can be flexibly arranged in the length and / or width direction 32 according to the amount of dried material and the land conditions, in order to expand the spreading area in accordance with the actual situation.

[0046] By providing ventilation holes 13, the material 0 has a larger contact area with the air. The material spreading plate 11 is fixed to the connector 12, which supports the spreading plate 11, allowing air to circulate from below and accelerating the drying of the material 0. The staggered distribution of the ventilation holes 13 ensures that all air flowing over the spreading plate 11 passes through them, maximizing the drying effect of the airflow on the material 0. Furthermore, through the cooperation between the first fixing structure 14 and the second fixing structure 15, the spreading area of ​​the spreading plate 11 can be arbitrarily expanded in the length direction 31 and / or width direction 32 to form various shapes such as a grid, L-shape, and + shape, suitable for different ground conditions.

[0047] In some embodiments, the material spreading plate 11 is integrally formed, and the two long sides of the material spreading plate 11 are bent at 90 degrees in the same direction.

[0048] For example, such as Figure 2As shown, the long sides of the material spreading plate 11 are bent in the same direction. In actual use, the bent sides can face the ground, ensuring that the lower surface of the material spreading plate 11 does not contact the object when placed on a flat surface, thus keeping it in an air-filled state. This allows air to flow over both the top and bottom surfaces of the material spreading plate 11, accelerating the drying of the material 0. When the material spreading plate 11 is supported by the connector 12, it can also provide more support at multiple locations, allowing for the placement of more types and weights of materials 0, increasing the load-bearing capacity of the material spreading plate 11.

[0049] In addition, the material laying plate 11 is manufactured using an integral molding and bending process, which can further increase the load-bearing capacity of the material laying plate 11, so that the long sides on both sides provide a supporting force opposite to the zero weight of the material, thereby increasing the supporting strength of the material laying plate 11.

[0050] In some embodiments, the connector 12 includes a linkage 16, which is fixedly connected to the second fixed structure 15, and the linkage 16 can roll on a plane.

[0051] Specifically, two adjacent connecting parts 12 are fixed to each other by a shaft connection, and the linkage 16 can be a sphere or ellipsoid that is rolled around the fixed shaft 162. The linkage 16 is fixedly connected to the second fixed structure 15, thereby being fixedly connected to the spreading plate 11. The rolling part of the linkage 16 extends beyond the height of the spreading plate 11, and the linkage 16 drives the spreading plate 11 to roll on the plane, thereby moving the spreading plate 11 and the material 0 on the spreading plate 11 by thrust, facilitating the movement of the spreading plate 11.

[0052] In some embodiments, the linkage 16 includes a rolling element 161 and a fixed shaft 162, wherein the rolling element 161 is axially connected and fixed to the fixed shaft 162.

[0053] Specifically, the rolling element 161 can be a sphere or ellipsoid with a through hole, and its cross-section along the length direction 31 is circular. The fixed shaft 162 passes through the through hole, and its two ends are respectively fixed to the connecting member 12, thereby fixing the rolling element 161 to the connecting member 12. The rolling element 161 can roll around the fixed shaft 162 as the center, thereby rolling on the plane and driving the material spreading plate 11 to move.

[0054] In some embodiments, the linkage 16 is a linkage shaft with a circular cross-section. The diameter of the linkage shaft at the rolling area is larger than the diameters at both ends of the linkage shaft, and the rolling area is located in the middle of the linkage shaft along the shaft length direction 31.

[0055] Specifically, the shaft length direction 31 can be the length direction 31 of the material plate 0. When the linkage 16 rolls, it causes the material plate 0 to move in the width direction 32. Correspondingly, the shaft length direction 31 can be the width direction 32 of the material plate 0. When the linkage 16 rolls, it causes the material plate 0 to move in the length direction 31.

[0056] Optionally, the linkage 16 can be an integral structure, with the middle protruding part being the rolling area and the two ends being fixed areas. The diameter of the rolling area is larger than that of the fixed areas and protrudes from the connector 12. The fixed areas at both ends are fixed to the connector 12. When the rolling area rolls, it drives the connector 12 and the material spreading plate 11 fixed to the connector 12 to move.

[0057] Optionally, such as Figure 4 As shown, in some embodiments, when the length of the spreading plate 11 is greater than or equal to the length threshold, at least one set of first fixing structures 14 are provided at the middle of both ends of the spreading plate 11 and are fixedly connected to the connector 12.

[0058] Specifically, the length threshold can be determined based on the material and parameters such as length, width, and thickness of the material plate 11. When the length of the material plate 11 is long, or when the material 0 placed on it is heavy, the connecting member 12 can be fixed by setting the first fixing structure 14 in the middle, so that the connecting member 12 provides support in the middle of the material 0 plate, increases the support force of the middle position of the material plate 11 on the material 0, and avoids deformation of the material plate 11.

[0059] For example, when the length of the spreading plate 11 is greater than or equal to a length threshold, a first fixing structure 14 can be provided between the two ends of the spreading plate 11 along the length direction 31. The first fixing structure 14 of the spreading plate 11 is fixed to the second fixing structure 15 of the connector 12, thereby fixing the connector 12 between the two ends of the spreading plate 11. For example, as Figure 4 As shown, along the length direction 31, a set of first fixing structures 14 are provided in the central area of ​​the spreading plate 11, which are fixedly connected to the second fixing structures 15 of the connector 12 to enhance the fixing and supporting effect and drive the spreading plate 11 to move. The central area of ​​the spreading plate 11 along the length direction 31 can be a straight plate without ventilation holes 13 to prevent material O from leaking from the ventilation holes 13 onto the connecting member 16 of the connector 12, thus affecting the movement effect.

[0060] In some embodiments, the material spreading device 1 may further include a motor 17 and a polygonal gear 18. The polygonal gear 18 meshes with the connector 12. The multiple material spreading plates 11, the connector 12 and the polygonal gear 18 constitute a conveying layer 19. The motor 17 drives the conveying layer 19 to transmit power.

[0061] For example, Figure 5 This is a schematic diagram of a transport layer structure provided in an embodiment of this application. For example... Figure 5As shown, multiple material spreading plates 11 are fixedly connected by a first connector 121 and a second connector 122 to form a conveyor layer 19 similar to a conveyor belt structure. Polygonal gears 18 are located at both ends of the conveyor layer 19. A motor 17 is connected to the polygonal gears 18 and controls the rotation of the polygonal gears 18. The material spreading plates 11 located at both ends of the conveyor layer 19 are always engaged with the polygonal gears 18. When the motor 17 controls the polygonal gears 18 to rotate, the material spreading plates 11 are driven by the polygonal gears 18 and thus rotate at the speed of the motor 17, thereby realizing the conveying of the material spreading plates 11.

[0062] In some embodiments, there are multiple transport layers 19. The multiple transport layers 19 are spaced apart in the vertical direction 33, and the beginning of the lower transport layer 19 in two adjacent layers protrudes from the end of the higher transport layer 19 in the horizontal direction 34.

[0063] Specifically, the beginning of the conveyor layer 19 can be understood as the feeding end of the conveyor layer 19, where material 0 is laid from the feeding end to the conveyor layer 19, and the end of the conveyor layer 19 can be understood as the discharging end of the conveyor layer 19, where material 0 is sent out of the conveyor layer 19 from the discharging end.

[0064] For example, Figure 6 This is a schematic diagram of a multi-layer distribution of the material spreading device provided in an embodiment of this application. For example... Figure 6 As shown, multiple conveyor layers 19 can be spaced out in the vertical direction 33, from top to bottom, with the beginning of each layer protruding beyond the end of the layer above to receive material 0 that falls naturally from the upper conveyor layer 19 during transport. For example, the beginning of the second layer protrudes beyond the end of the first layer, so that material 0 falls from the end of the first layer to the beginning of the second layer, continues to be transported to the end by the second conveyor layer 19, and is then caught by the beginning of the third conveyor layer 19 protruding beyond the end of the second layer, and so on, continuing the transport. By staggering multiple conveyor layers 19, material 0 can be transported from top to bottom between multiple conveyor layers 19 while greatly saving floor space.

[0065] Based on the above embodiments, this application also provides a drying system 20. Figure 7 This is a schematic diagram of the structure of a drying system provided in an embodiment of this application. Figure 7 As shown, the air drying system 20 provided in this application embodiment includes an air drying chamber and a material spreading device 1 of any of the above embodiments. The material spreading device 1 is located in the air drying chamber 202 of the air drying chamber, and at least one axial flow fan 203 is provided between the air drying unit 201 and the air drying chamber 202. The airflow direction of the axial flow fan 203 is the direction from the air drying unit 201 toward the air drying chamber 202.

[0066] By installing an axial flow fan 203 between the air drying unit 201 and the air drying chamber 202, the air in the air drying unit 201 can always be blown towards the material spreading device 1 in the air drying chamber 202, thereby circulating the air in the air drying system 20 and drying the material 0.

[0067] Optionally, the drying unit 201 may include a heating device to increase the temperature of the air in the drying unit 201, thereby making the airflow blown by the axial fan 203 into the drying chamber 202 hot air, accelerating the drying of the material 0. This also maintains the temperature inside the drying chamber 202 at a consistently high level, ensuring that the material 0 is dried by the high-temperature gas within the drying chamber 202. Drying and air drying occur simultaneously, ensuring efficient drying of manure and waste.

[0068] In some embodiments, the material spreading device 1 is at least one layer of spreading plate 11, each layer of spreading plate 11 corresponds to at least one axial flow fan 203, and the axial flow fan 203 is located below the spreading plate 11.

[0069] Specifically, such as Figure 7 As shown, the multi-layer material spreading plates 11 can be distributed vertically, thus saving floor space. The axial flow fan 203 is located below the material spreading plates 11, so that the hot airflow blown by the axial flow fan 203 passes over the lower surface of the material 0, carrying away moisture. Furthermore, the hot airflow will spontaneously move upward, thus filling the entire drying chamber 202, further drying the material 0.

[0070] Optionally, such as Figure 5 and Figure 6 As shown, in some embodiments, the material spreading device 1 includes multiple staggered conveyor layers 19. Each conveyor layer 19 consists of multiple spreading plates 11, connectors 12, a motor 17, and a hexagonal gear. The motor 17 drives the conveyor layer 19 to transport material 0 from top to bottom to the bottom outlet. During the process, the material 0 is accelerated to dry by a drying chamber and an axial flow fan 203. At this time, the conveying speed of the material 0 controlled by the motor 17 can be determined according to the conveying distance and time of the material 0 from the inlet to the outlet. The conveying time can be determined by the drying speed of the drying chamber, thereby realizing fully automated control of the drying process, reducing human intervention, and reducing odor leakage.

[0071] The air-drying system 20 provided in this application embodiment, by setting up a material spreading device 1 in a closed air-drying room and blowing air onto the material spreading device 1 by an axial flow fan 203, can make the airflow always pass over 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 manure.

[0072] In summary, the material spreading device 1 and drying system 20 provided in this application embodiment, by setting ventilation holes 13, allow for a larger contact area between the material 0 and the air. The material spreading plate 11 is fixed to the connecting member 12, which can be used to support the material spreading plate 11, allowing air to circulate from below, accelerating the drying of the material 0. The staggered distribution of the ventilation holes 13 ensures that all air flowing over the material spreading plate 11 passes through the ventilation holes 13, without wasting the drying effect of the flowing air on the material 0. Furthermore, through the cooperation between the first fixing structure 14 and the second fixing structure 15, the spreading area of ​​the material spreading plate 11 can be arbitrarily expanded in the length direction 31 and / or width direction 32, forming various shapes such as a grid, L-shape, and + shape, suitable for different ground conditions. By setting the material spreading device 1 in a sealed drying chamber and blowing air onto the material spreading device 1 using an axial flow fan 203, the airflow can always pass over the material 0, thereby removing moisture from the material 0, accelerating the drying of the material 0, and effectively improving the drying efficiency of manure.
