The embodiment of the application provides an unmanned mobile device (not shown) which is used for spreading materials, so that the materials can be spread to a specified position, and the spreading operation is completed. The unmanned mobile device can be applied to sowing operations in agriculture, such as seed sowing, fertilizer sowing, pesticide sowing and the like; of course, the unmanned mobile device can also be applied to the breeding industry, such as feed scattering and the like; in addition, the unmanned mobile device can also be used for scattering other materials in solid state, particle state or condensed grease state, and the like, and the details are not repeated herein.

In addition, the unmanned mobile equipment provided by the application can move according to a route set by a user, and in the moving process according to the set route, the unmanned mobile equipment can be used for spreading materials at a specified position. The mode of the unmanned mobile device moving according to the set route may be land walking, flying, water walking, or the like.

The unmanned mobile equipment comprises a mobile carrier, a conveying device and a sowing system. The conveying device and the sowing system are arranged on the movable carrier, and the movable carrier can provide a bearing effect for the conveying device and the sowing system so as to ensure that the conveying device and the sowing system stably operate. The movable carrier is provided with a power structure for moving the movable carrier, and the power structure can be a walking wheel, a propeller or a jet power device and the like. The movable carrier is also provided with a storage container, an energy device, a control device and the like. The storage container can be used for storing materials; the energy device may provide a source of energy to the power structure, including but not limited to electrical energy and energy from combustion; the control means may then be used to control the operation of the power structure so that the mobile carrier may be moved according to a route set by the user.

Conveyor connects in the storing container, and conveyor can derive the material in the storing container and carry to the system of scattering. The sowing system is connected with the conveying device to receive the materials conveyed by the conveying device, and can also be used for sowing the received materials to a specified position, so that the sowing operation is completed. The conveying device and the sowing system are both electrically connected with the control device; the control device can control the conveying device to operate so as to convey the materials at the designated time and ensure that enough materials are conveyed to the sowing system; the control device can also control the scattering system to scatter at the appointed time and the appointed position, so that the materials can be scattered to the appointed position to complete the scattering operation.

The system comprises a movable carrier, a sowing system and a sowing device, wherein the sowing system is arranged on the movable carrier and can be used for sowing materials; of course, the conveying means is connected to the spreading means for conveying the material to the spreading means. The scattering device may comprise a housing (not shown) and a scattering disk 10. The shell is connected with the conveying device, and a space for receiving materials is arranged inside the shell, in other words, when the conveying device conveys the materials to the shell, the materials received by the shell enter the inner space of the shell. In order to facilitate the material to enter and lead out the inner space of the shell, a feeding port and a discharging port are formed in the shell, the feeding port is used for feeding the material into the inner space of the shell, and the discharging port is used for leading the material out of the inner space of the shell. The spreading tray 10 is rotatably disposed in the inner space of the housing so that the material can contact with the spreading tray 10 after entering the inner space of the housing, and the material can be pulled out from the discharge port while the spreading tray 10 rotates, thereby spreading the material to a designated position to complete a spreading operation.

In prior art, because the setting mode of the plectrum that sets up on the scattering dish roughly sets up a plurality of plectrums along the diameter direction of scattering dish, make from this and scatter the pivoted in-process at the scattering dish, drive the material and derive from the discharge gate through following a plurality of plectrums of scattering dish pivoted to accomplish and scatter the operation. It should be noted that, in the above-mentioned manner adopted in the prior art, the centrifugal acting force generated by the material during the rotation of the scattering disk makes the material thrown out, so that the scattering direction of the material can only be along the tangential direction of the throwing position, in other words, in the prior art, the direction in which the material is thrown out is single, which results in a small range of material scattering, further results in that the material is difficult to uniformly scatter, reduces the scattering effect of the material, and affects the use experience.

In order to improve the above problems, in other words, to improve the technical problem of uneven spreading in the prior art, please refer to fig. 1, which provides a spreading plate 10 and an unmanned spreading machine using the spreading plate 10 in the embodiment of the present application.

Referring to fig. 2, the scattering disk 10 includes a rotating disk 100 and a first scattering sheet 110. The rotating disk 100 is configured to be rotatably connected to the housing, and the rotating disk 100 is located in the inner space of the housing, so that the rotating disk 100 can receive the material when the material enters the inner space of the housing from the material inlet. The first spreading pieces 110 are provided on the rotary disk 100, and the first spreading pieces 110 are provided at one side of the rotary disk 100 in an axial direction thereof, so that after the rotary disk 100 receives the material, the material can move along the rotary disk 100 to be in contact with the first spreading pieces 110, so that the first spreading pieces 110 can pull the material out of the discharge port to complete spreading of the material. The first scattering tabs 110 and the diameter of the rotating disc 100 passing the first scattering tabs 110 form a first angle 111, and the first angle 111 is an acute angle. In other words, the first scattering pieces 110 are disposed obliquely with respect to the diameter of the rotating disk 100 passing through the first scattering pieces 110. The angle α in fig. 2 is the first angle 111.

The above-mentioned "diameter of the first dust distribution plate 110 on the rotating disc 100" may refer to an angle formed by the first dust distribution plate 110 and a reference straight line, which is a diameter passing through an end of the first dust distribution plate 110 near the center of the rotating disc 100. Of course, the reference line may have a deviation in other embodiments of the present application. For example, a straight reference line with a diameter tangent to the end of the first spreading tab 110, such as an included angle indicated by c in fig. 3; for another example, the side of the first spreading sheet 110 away from the center of the rotating disc 100 has a first side near the center of the rotating disc, and the diameter of the first side is taken as a reference straight line; also for example, the side of the first spreading sheet 110 facing the center of the rotating disk 100 has a second side near the center, a diameter intersecting the second side is taken as a reference line, and the like.

It should be noted that in some embodiments of the present application, the scattering device is vertically disposed, and may be considered as a scattering disk 10 that is vertically disposed, and the housing is also vertically disposed to accommodate the arrangement of the scattering disk 10. The fact that the sowing tray 10 is vertically arranged means that under the condition that the unmanned sowing machine is normally placed on a horizontal plane, the included angle between the rotating central axis of the sowing tray 10 and the horizontal plane is smaller than 90 degrees, for example, a zero angle is formed between the rotating central axis of the sowing tray 10 and the horizontal plane, namely the rotating central axis is parallel to the horizontal plane; also for example, the central axis of rotation of the tray 10 may form an acute angle with the horizontal, such as 30 °, 45 °, 60 °, 75 °, or 85 °.

In addition, based on the vertical arrangement of the spreading disk 10, there is a certain distance between the first spreading pieces 110 and the rotation center of the rotating disk 100, and an area for receiving the material is formed in an area between the first spreading pieces 110 and the rotation center of the rotating disk 100, in other words, the material is received by the area between the first spreading pieces 110 and the rotation center of the rotating disk 100 after the material enters the inner space of the housing through the feeding port.

It should be noted that, since the spreading plate 10 is vertically arranged and there is a gap between the first spreading sheet 110 and the rotation center of the rotating plate 100, the material falls down under its own weight until the material falls down to be in contact with the first spreading sheet 110 under the condition that the material enters the inside of the housing. The first spreading pieces 110 rotating along with the rotating disc 100 provide a beating force to the material, so as to beat the material out of the discharge opening, thereby completing the spreading of the material. Wherein, it should be noted that, for the convenience of scattering of material, at least part discharge gate is located the bottom of shell, and when the material entered into the inner space of shell from the pan feeding mouth this moment, the material was then fallen to the discharge gate under self action of gravity.

As described above, the material is pulled out from the discharge opening by the beating of the first scattering pieces 110 while falling to be able to contact with the first scattering pieces 110. Because the first spreading pieces 110 form an acute angle with the diameter of the rotating disc 100 passing through the first spreading pieces 110, compared with the shifting pieces arranged along the diameter direction of the rotating disc 100 in the prior art, the acting force provided by the first spreading pieces 110 to the materials provided by the application has a component force along the radial direction of the rotating disc 100, so that the initial speed of the materials can be resolved into the speed along the radial direction of the rotating disc 100, the amount inside the refuted shell is reduced, the spreading range can be increased, the spreading range can be uniformly performed, and the technical problem of uneven spreading in the prior art is solved.

It is noted that, in the embodiment of the present application, the number of the first spreading pieces 110 is plural, and the plural first spreading pieces 110 are arranged at intervals around the rotation center of the rotary disk 100, thereby allowing the plural first spreading pieces 110 to continuously provide a beating action to the materials during the rotation of the rotary disk 100, thereby allowing the materials to be continuously spread to continuously perform the spreading work.

Of course, in the following embodiments of the present application, a manner in which the sowing tray 10 is vertically disposed with a space between the first sowing pieces 110 and the rotation center of the rotating tray 100 is exemplified.

Alternatively, in some embodiments of the present application, referring to fig. 3, in order to adjust the spreading range of the spreading tray 10, the first spreading sheet 110 is rotatably connected to the rotating tray 100 to adjust the angle of the first angle 111. In other words, the purpose of adjusting the inclination angle of the first spreading pieces 110 can be achieved by turning over the first spreading pieces 110, so that the moving direction of the material pulled out by the first spreading pieces 110 can be changed, and the spreading range of the material can be adjusted.

Here, the connection position of the first scattering sheet 110 and the rotating disc 100 may be regarded as a straight line, and the first scattering sheet 110 may be rotatably connected to the rotating disc 100 at a position located at one end of the straight line, and at the same time, other positions of the first scattering sheet 110 may be movably engaged with the rotating disc 100, so that the angle adjustment of the first angle 111 may be achieved by rotating the first scattering sheet 110 relative to the rotating disc 100. It should be understood that in other embodiments of the present application, other arrangements may be used, for example, a plurality of mounting stations (not shown) may be provided on the rotating disc 100 for each first spreading sheet 110, and in the case that the first spreading sheets 110 are mounted at different mounting stations, the first corners 111 formed by the first spreading sheets 110 are different, so that the angle of the first corners 111 may be adjusted by adjusting the mounting stations of the first spreading sheets 110.

It should be noted that, in order to ensure the stability of the first dust application 110 after the position adjustment, in the embodiment of the present application, after the first dust application 110 rotates relative to the rotating disk 100, the position stability of the first dust application 110 may be ensured by the first dust application 110 engaging with the rotating disk 100. The first spreading tab 110 may be clamped with respect to the rotating disc 100 as follows: the position where the first scattering sheets 110 are movably connected with the rotating disc 100 has a rotational damping so that the first scattering sheets 110 can rotate under a large acting force, and the first scattering sheets 110 ensure the position stability through the rotational damping under the action of canceling the external force; alternatively, the side of the first spreading member 110 close to the rotating disc 100 is provided with a retractable abutting member (not shown), which can be extended to abut against the rotating disc 100 to provide a limiting function for the first spreading member 110, thereby ensuring the position stability of the first spreading member 110, and of course, in case of retracting the abutting member, the first spreading member 110 can rotate relative to the rotating disc 100, wherein the abutting member can be a bolt or the like provided on the first spreading member 110 through a threaded hole.

Optionally, in some embodiments of the present application, the first spreading sheet 110 includes a sheet main body 112, a first connection portion 113 and a second connection portion 114, and the first connection portion 113 and the second connection portion 114 are disposed on the sheet main body 112 at intervals. Correspondingly, the rotating disc 100 is provided with a sliding rail structure 150, and the sliding rail structure 150 extends along an arc-shaped path. Wherein, the first connecting portion 113 is rotatably connected to the rotating disc 100, and the first connecting portion 112 is located on the center of the arc path of the sliding rail structure 150; the second connecting portion 114 is movably mounted to the slide rail structure 150. Accordingly, the sheet main body 112 and the rotary disc 100 form the first corner 111 through the diameter of the sheet main body 112, and the sheet main body 112 can be driven to rotate around the first connection portion 113 under the condition that the second connection portion 114 slides along the slide rail structure 150, so as to adjust the angle of the first corner 111.

In view of this, in some embodiments of the present application, the first angle 111 may also be formed as an angle formed between a diameter of the rotating disc 100 passing through the axis of the first connecting portion 113 and the sheet main body 112, as indicated by b in fig. 3. In addition, in some embodiments, a connection line between the first connection portion 113 and the second connection portion 114 substantially coincides with or is parallel to a plane where the sheet main body 112 is located, in which case, the first angle 111 may also be formed as an included angle formed by a diameter of the rotating disc 100 passing through an axis of the first connection portion 113 and a connection line between the first connection portion 113 and the second connection portion 114. Of course, in other embodiments, a connection line between the first connection portion 113 and the second connection portion 114 may form an included angle with a plane where the sheet main body 112 is located, and in this case, the first angle 111 is formed in a manner that an included angle is formed between a diameter of the rotating disc 100 passing through an axis of the first connection portion 113 and the sheet main body 112.

It should be noted that the first connecting portion 113 and the second connecting portion 114 are both convexly disposed on the same side of the sheet main body 112, and the distance between the first connecting portion 113 and the second connecting portion 114 is smaller than the width of the sheet main body 112, so that the rotation amplitude of the sheet main body 112 can be reduced, and the rotation of the sheet main body 112 is prevented from being affected by other spreading sheets. Alternatively, in some embodiments, the position where the first connecting portion 113 is disposed may be the middle of the side of the sheet main body 112 where the first connecting portion 113 and the second connecting portion 114 are disposed; of course, the second connection portion 114 may be provided at the middle of the side surface.

Alternatively, in some embodiments of the present application, the sliding rail structure 150 may be an arc-shaped groove 151 disposed on the rotating disc 100, and the second connecting portion 114 is slidably engaged with the arc-shaped groove 151, so that a guiding function and a limiting function can be provided for the second connecting portion 114 through the arc-shaped groove 151, and the second connecting portion 114 can be ensured to stably slide in the arc-shaped groove 151, so as to adjust the angle of the first corner 111.

Based on this, in order to secure the positional stability after the sheet main body 112 is rotated, the second connection portion 114 may be a bolt structure provided on the sheet main body 112. At this time, the second connecting portion 114 may be screwed into the sheet main body 112 to clamp the rotating disc 100 together with the sheet main body 112 so as to stabilize the position of the sheet main body 112, or the second connecting portion 114 may be screwed out of the sheet main body 112 so that the sheet main body 112 may freely rotate relative to the rotating disc 100.

It should be understood that in other embodiments of the present application, the slide rail structure 150 may also be configured as other types of structures, for example, the slide rail structure 150 is a guide rail disposed on the rotary disc 100, and the second connecting portion 114 is provided with a sliding slot adapted to the slide rail structure 150, so that the sliding fit between the second connecting portion 114 and the slide rail structure 150 can be achieved through the sliding fit between the guide rail and the sliding slot. In order to ensure positional stability of the sheet main body 112 after adjusting the angle of the first corner 111, the guide rail and the chute may be damping-fitted.

Of course, in other embodiments of the present application, the movable arrangement of the first scattering sheets 110 may be eliminated, so that the first corners 111 formed by the first scattering sheets 110 are fixed.

Optionally, in some embodiments of the present application, in order to increase the spreading range of the spreading disk 10 and improve the spreading uniformity, the rotating disk 100 further includes a second spreading sheet 120. The second spreading pieces 120 are disposed adjacent to the first spreading pieces 110, and the second spreading pieces 120 form a second angle with the diameter of the rotating disc 100 passing the second spreading pieces 120; the angle of the first angle 111 is different from the angle of the second angle. In other words, when the first spreading pieces 110 and the second spreading pieces 120 are sequentially rotated to the same position at the discharge port, the first spreading pieces 110 and the second spreading pieces 120 are inclined at different angles with respect to the horizontal plane, so that the initial velocity direction of the material beaten by the first spreading pieces 110 is different from the initial velocity direction of the material beaten by the second spreading pieces 120, so that the materials can be made to have a plurality of spreading directions in the process of being beaten by the first spreading pieces 110 and the second spreading pieces 120, and thus the spreading range of the materials can be expanded to facilitate uniform spreading of the materials.

It should be noted that, in order to ensure that the second scattering pieces 120 can effectively beat the material, alternatively, the second scattering pieces 120 are spaced from the rotation center of the rotary disc 100, in other words, the first scattering pieces 110 and the second scattering pieces 120 are spaced from the rotation center of the rotary disc 100, so that an area for receiving the material is formed at the rotation center position of the rotary disc 100, and in case the material enters the inner space of the housing, the material is received by the feeding area at the rotation center position of the rotary disc 100, and then the material drops toward the discharging port under its own gravity until the material is beaten out by the first scattering pieces 110 or the second scattering pieces 120.

It should be noted that, in some embodiments of the present application, the feeding area is formed between the first scattering sheets 110 and the rotation center of the rotary disk 100, in other words, since one end of the first scattering sheets 110 near the rotation center of the rotary disk 100 has a distance from the center of the rotary disk 100, the feeding area is formed by an area where the distance is located. Of course, the feeding area is also located between the second spreading tabs 120 and the rotation center of the rotary disk 100. It should be understood that in other embodiments of the present application, the feeding area may also cover a portion of the first spreading tabs 110 and a portion of the second spreading tabs 120, in other words, an end portion of the first spreading tabs 110 near the center of rotation of the rotary disc 100 and an end portion of the second spreading tabs 120 near the center of rotation of the rotary disc 100 are located inside the feeding area, so that a portion of the material after entering the feeding area may be directly beaten by the first spreading tabs 110 and the second spreading tabs 120, thereby directly beating out to complete the spreading. Of course, in the case where portions of the first scattering sheets 110 are located in the feeding area, it can also be considered that the feeding area is formed between the first scattering sheets 110 and the rotation center of the rotating disk 100.

In order to ensure that the spreading range can be expanded when any position of the spreading disk 10 is rotated to the discharge opening, in some embodiments of the present application, the number of the second spreading tabs 120 is multiple, the multiple second spreading tabs 120 are staggered with the multiple first spreading tabs 110, in other words, one second spreading tab 120 is provided between any two adjacent first spreading tabs 110, and one first spreading tab 110 is provided between any two adjacent second spreading tabs 120. Of course, one first spreading sheet 110 and one second spreading sheet 120 adjacently disposed may be regarded as one spreading sheet group 101, and a plurality of first spreading sheets 110 and a plurality of second spreading sheets 120 form a plurality of spreading sheet groups 101, and the plurality of spreading sheet groups 101 are disposed at intervals around the rotation center of the rotating disc 100. Therefore, in the rotating process of the rotating disc 100, a plurality of spreading groups 101 can be used for beating materials in turn, the purpose of spreading the materials from multiple angles can be achieved at any time, and the problem of uneven material spreading in the prior art is solved.

Of course, in other embodiments of the present application, the second spreading pieces 120 may be rotatably connected to the rotating disc 100, in other words, the second spreading pieces 120 may be assembled with the rotating disc 100 in the same manner as the first spreading pieces 110 and the rotating disc 100, as shown in fig. 3, which is not described herein again.

It should be understood that, referring to fig. 2 and fig. 4 in combination, in other embodiments of the present application, each group of broadcast seeds 101 may include not only the first broadcast seeds 110 and the second broadcast seeds 120, in other words, a part or all of the group of broadcast seeds 101 may include the third broadcast seeds 130, the fourth broadcast seeds, or the fifth broadcast seeds, etc. Here, it is described as an example that each of the broadcast piece groups 101 includes a first broadcast piece 110, a second broadcast piece 120, and a third broadcast piece 130. In each spreading piece group 101, the first spreading pieces 110, the second spreading pieces 120 and the third spreading pieces 130 are arranged at intervals to ensure that the first spreading pieces 110, the second spreading pieces 120 and the third spreading pieces 130 can effectively flap materials in the rotating process; in addition, a third angle (not shown) is formed between the third spreading pieces 130 and the diameter of the rotating disk 100 passing through the third spreading pieces 130, and the third angle may be the same as the first angle 111, the third angle may be the same as the second angle, and the third angle may be different from both the first angle 111 and the second angle. If the angle for spreading the material is increased further, the third angle may be set to be different from both the first angle 111 and the second angle, so that each spreading piece group 101 can at least make the material be pulled out from the discharge port from three directions; if in order to improve the material discharge amount at one of the angles, one of the first angle 111 and the second angle is the same as the third angle, so that in each scattering set 101, the angles of the material discharged by at least two scattering sheets with the same angle are the same, and the material discharge at the angle is sufficient, thereby achieving the preset scattering effect.

It should be noted that, in order to ensure that the plurality of first spreading pieces 110, the plurality of second spreading pieces 120 and the plurality of third spreading pieces 130 are all arranged in a staggered manner, so as to improve the uniformity of spreading, in the plurality of spreading group 101, the first spreading pieces 110, the second spreading pieces 120 and the third spreading pieces 130 are arranged in the same manner. In other words, in one of the groups of seeds 101 the first seed 110 is located between the second seed 120 and the third seed 130 and the second seed 120 is located on the clockwise side of the third seed 130, then in the remaining groups of seeds 101, likewise, the first seed 110 is located between the second seed 120 and the third seed 130 and the second seed 120 is located on the clockwise side of the third seed 130. By adopting the arrangement mode, under the condition that the rotating disc 100 rotates to drive the plurality of scattering sheet groups 101 to rotate so as to scatter materials, the mode that the plurality of scattering sheet groups 101 scatter the materials is regular and convenient to control, so that the materials are scattered uniformly and conveniently.

It should be understood that in other embodiments of the present application, the first, second and third spreaders 110, 120, 130 of the plurality of groups 101 may not all be in the same arrangement, e.g., in another group 101, the first spreader 110 is located between the second and third spreaders 120, 130, and in another group 101, the second spreader 120 is located between the first and third spreaders 110, 130, etc.

In addition, in some embodiments of the present application, in the case where the third spreading pieces 130 are additionally provided in each of the spreading piece groups 101, there is also a gap between the third spreading pieces 130 and the rotation center of the rotating disc 100, thereby making it possible to prevent the third spreading pieces 130 from affecting the falling of the material when the material enters the feeding area of the rotation center area of the rotating disc 100, thereby ensuring that the material falls orderly to the discharge port to be spread by the plurality of spreading piece groups 101.

In some embodiments of the present application, the first, second and third spreading pieces 110, 120 and 130 are spaced apart from the rotation center of the rotary disk 100 by the same distance, so that the material can contact the first, second and third spreading pieces 110, 120 and 130 when falling by the same distance, and thus, the material is prevented from being distributed unevenly when one of the spreading pieces contacts the material in advance, and the material is prevented from being distributed unevenly when the one of the spreading pieces contacts the material in advance.

Similarly, the width of the first distribution pieces 110 in the radial direction of the rotary disk 100, the width of the second distribution pieces 120 in the radial direction of the rotary disk 100, and the width of the third distribution pieces 130 in the radial direction of the rotary disk 100 are the same, so that the first distribution pieces 110, the second distribution pieces 120, and the third distribution pieces 130 provide the same beating area, and thus can contact approximately the same amount of material, thereby ensuring that the plurality of first distribution pieces 110, the plurality of second distribution pieces 120, and the plurality of third distribution pieces 130 can uniformly stir out the material in the process of rotating along with the rotary disk 100, and achieving the purpose of uniform distribution.

In addition, in the case where the plurality of first distribution pieces 110, the plurality of second distribution pieces 120, and the plurality of third distribution pieces 130 are arranged to be staggered with each other, the distances between any two adjacent distribution pieces are the same; in other words, the distance between each group of seeding sheets 101 is the same, and the distance between the plurality of seeding sheets in each group of seeding sheets 101 is the same and equal to the distance between two adjacent groups of seeding sheets 101, so that substantially equal amount of material can be received between any two adjacent seeding sheets for uniform seeding.

It should be understood that in other embodiments of the present application, the distances between the groups of seeds 101 may not all be the same, and the distances between the plurality of seeds in each group of seeds 101 may not all be the same.

In other words, in some embodiments of the present application, the plurality of first scattering sheets 110 are centrosymmetric with respect to the center of the rotating disk 100; and/or the plurality of second spreading pieces 120 are formed to be symmetrical with respect to the center of the rotary disk 100. Wherein "and/or" means that only a plurality of first distribution pieces 110 may be arranged in central symmetry with respect to the center of the rotary disk 100; only the plurality of second spreading pieces 120 may be arranged in a central symmetry with respect to the center of the rotary disk 100; of course, the plurality of first distribution pieces 110 may be arranged to be centrosymmetric with respect to the center of the rotary disk 100, and the plurality of second distribution pieces 120 may be arranged to be centrosymmetric with respect to the center of the rotary disk 100. It should be understood that in the case of additionally providing the third distribution pieces 130, the plurality of third distribution pieces 130 may be provided to be centrosymmetric with respect to the center of the rotating disk 100, and of course, the manner of arranging the plurality of third distribution pieces 130 to be centrosymmetric may be eliminated.

Optionally, in some embodiments of the present application, the second angle ranges from 0 to 90 °. In other words, under the condition that the angle of the first angle 111 is different from the angle of the second angle, the angle of the second angle can be any value between 0 and 90 degrees, so that the moving directions of the materials discharged by the first spreading pieces 110 and the second spreading pieces 120 are different, multi-angle spreading of the materials is realized, and the problem of uneven spreading of the materials in the prior art is solved.

For example, as shown in fig. 2, in case that the first angle 111 is an acute angle, the second angle may be a zero angle, in other words, the second spreading pieces 120 are arranged in a radial direction of the rotary disk 100. Of course, in other embodiments, the angle of the second angle may also be an acute angle, for example, when the first angle 111 is 30 °, the second angle may also be 5 °, 10 °, 15 °, 20 °, 25 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, or 75 °. It should be understood that in other embodiments of the present application, the value of the first angle 111 may take other values, for example, the value of the first angle 111 is 5 °, 10 °, 15 °, 20 °, 25 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 67.03 °, 75 °, or the like.

It is worth mentioning that in order to ensure that the first and second spreading tabs 110, 120 can effectively provide a beating force to the material, so that the material can be effectively discharged from the discharge opening, optionally a first angle 111 formed between the first spreading tab 110 and the diameter of the rotating disc 100 passing the first spreading tab 110 has a value of 45 ° or less, and similarly a second angle formed between the second spreading tab 120 and the diameter of the rotating disc 100 passing the second spreading tab 120 has a value of 45 ° or less. Under the condition that the angle of the first angle 111 is smaller than or equal to 45 degrees, the included angle between the first sowing piece 110 and the horizontal plane is not too gentle when the first sowing piece rotates to the discharge port, so that effective beating force can be provided for materials, and the materials can be conveniently discharged; in addition, if the first corner 111 is too large, the amount of the material that is flaked back into the housing will increase, thereby affecting the spreading of the material. Similarly, when the angle of the second angle is smaller than or equal to 45 °, the included angle between the second spreading piece 120 and the horizontal plane when the second spreading piece rotates to the discharge port is not too gentle, so that an effective flapping action force can be provided for the materials, and the materials can be conveniently discharged; in addition, in the case of an excessively large second angle, the amount of material that is beaten back into the housing is increased, thereby affecting the spreading of the material.

Alternatively, in some embodiments of the present application, in order to facilitate the first spreading tabs 110 to provide a flapping force to the material such that the material can be effectively spread, the first spreading tabs 110 are perpendicular to the rotating disc 100. Note that, in the case where the first scattering sheets 110 have a substantially flat plate shape, the plane of the first scattering sheets 110 is substantially perpendicular to the plane of the rotary disk 100. Wherein the first spreading pieces 110 are arranged perpendicular to the rotating disc 100, and the flapping action of the first spreading pieces 110 to the material is perpendicular to the plane of the first spreading pieces 110 during the rotation of the rotating disc 100, on the basis of which the force to the material is prevented from having a component in the axial direction of the rotating disc 100, in other words, the material is prevented from having a large displacement in the axial direction of the rotating disc 100, thereby ensuring a strong controllability of the spreading range of the material, and thus facilitating uniform spreading.

Similarly, in some embodiments of the present application, in order to facilitate the second spreading blades 120 to provide a flapping force to the material, so that the material can be effectively spread, the second spreading blades 120 are perpendicular to the rotating disc 100. Wherein the second scattering pieces 120 have a substantially flat plate shape, in which case the plane of the second scattering pieces 120 is substantially perpendicular to the plane of the rotating disc 100. Wherein the second spreading pieces 120 are arranged perpendicular to the rotating disc 100, and the flapping action of the second spreading pieces 120 to the material is perpendicular to the plane of the second spreading pieces 120 during the rotation of the rotating disc 100, on the basis of which the force provided to the material is prevented from having a component in the axial direction of the rotating disc 100, in other words, the material is prevented from having a large displacement in the axial direction of the rotating disc 100, thereby ensuring a strong controllability of the spreading range of the material, and thus facilitating uniform spreading.

Of course, in case the third scattering sheets 130 are provided, the third scattering sheets 130 are also perpendicular to the rotary disk 100.

It should be understood that in other embodiments of the present application, the arrangement of the rotating disc 100, the first scattering tabs 110, the second scattering tabs 120 and the third scattering tabs 130 may also be different. For example, at least one of the first, second and third scattering sheets 110, 120 and 130 is provided in an arc shape which is an arc shape bent with an axis perpendicular to the rotation plane, in other words, a central depression or protrusion of at least one of the first, second and third scattering sheets 110, 120 and 130 is formed in an arc shape formed by a partial cylinder. For another example, the middle of the rotating disk 100 is concave or convex such that the rotating disk 100 has a substantially spherical or conical shape, and in this case, the rotating disk 100 also has a central rotation axis, and in the case where the first, second and third distribution pieces 110, 120 and 130 are parallel to the central rotation axis, the first, second and third distribution pieces 110, 120 and 130 can be considered to be perpendicular to the rotating disk 100.

In addition, in some embodiments of the present application, the first spreading sheet 110 is integrally formed with the rotating disk 100. By molding the first scattering sheets 110 on the rotary disk 100 in an integrated manner, the stability of the connection between the first scattering sheets 110 and the rotary disk 100 may be improved, and thus the lifespan of the scattering disk 10 may be improved. Of course, in other embodiments of the present application, the first spreading tab 110 may be disposed on the rotating disk 100 in other manners, such as welding, bonding, clipping, or screwing. Likewise, in some embodiments of the present application, the second and third spreading tabs 120 and 130 are also integrally formed with the rotary disk 100, thereby improving the stability of the connection of both the second and third spreading tabs 120 and 130 to the rotary disk 100. Of course, in other embodiments of the present application, at least one of the second and third dust spreading tabs 120 and 130 may be connected to the rotary disk 100 in other manners, for example, the second dust spreading tab 120 may be connected to the rotary disk 100 by welding, bonding, clipping or screwing. Also for example, the third spreading tabs 130 are coupled to the rotating disc 100 by welding, bonding, clipping or screwing.

The first spreading pieces 110, the second spreading pieces 120 and the third spreading pieces 130 may be integrally formed with the rotating disc 100 by injection molding, cutting or hot melt connection.

In the embodiment of the present application, in order to facilitate the rotation of the rotating disc 100 and the outer housing, a rotation connecting column 140 is provided at a rotation center position of the rotating disc 100, the rotation connecting column 140 is convexly provided on the rotating disc 100, and the rotation connecting column 140, the first scattering pieces 110, the second scattering pieces 120 and the third scattering pieces 130 are located at a same side surface of the rotating disc 100. In the case that the rotation connection column 140 is rotatably coupled to the housing, a space for receiving the material is formed between the feeding area of the rotation disc 100 and the housing, so that the material can fall toward the discharge hole after entering the space, thereby facilitating the material to be spread by the first spreading pieces 110, the second spreading pieces 120 and the third spreading pieces 130. It should be noted that the rotation connecting column 140 is integrally formed with the rotation disk 100, thereby improving the connection stability between the rotation connecting column 140 and the rotation disk 100. The rotation connection post 140 and the rotation disc 100 are integrally formed by injection molding, cutting or hot melting.

It should be understood that in other embodiments of the present application, the rotation connection post 140 can be connected to the rotation disc 100 by other methods, such as welding, bonding, clipping, or screwing.

In summary, the spreading disk 10 and the unmanned spreading machine provided in the embodiment of the present application can rotate the first spreading pieces 110 along the rotating disk 100 in the process of rotating the spreading disk 10, and since the first spreading pieces 110 form an acute angle with respect to the diameter of the rotating disk 100 passing through the first spreading pieces 110, compared with the shifting pieces arranged along the diameter direction of the rotating disk 100 in the prior art, the acting force provided by the first spreading pieces 110 to the material by the present application has a component force along the radial direction of the rotating disk 100, so that the initial speed of the material can be resolved into the speed along the radial direction of the rotating disk 100, thereby reducing the amount inside the refuted housing, and thus the spreading range can be increased, thereby uniformly spreading the material, and improving the technical problem of non-uniform spreading in the prior art.

In addition, the second spreading pieces 120 are further disposed in the spreading disk 10, and a second angle formed by the second spreading pieces 120 relative to the rotating disk 100 through the diameter of the second spreading pieces 120 is different from the angle of the first angle 111 formed by the first spreading pieces 110 and the corresponding diameter of the rotating disk 100, so that when the first spreading pieces 110 and the second spreading pieces 120 rotate along with the rotating disk 100, the moving direction of the material pulled out by the first spreading pieces 110 is different from the moving direction of the material pulled out by the second spreading pieces 120, and thus the material can be pulled out from multiple angles, thereby further expanding the spreading range of the material, realizing uniform spreading of the material, and improving the technical problem of non-uniform spreading in the prior art.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
