The mechanism 100 of scattering that this embodiment provided is applied to unmanned aerial vehicle, along with unmanned aerial vehicle scatters the development of operation, because of its have flexible, the reaction fast, unmanned aerial vehicle flight, the operation requirement low operation fast advantage such as, the speed of popularization accelerates greatly, has obtained the wide application. The sowing mechanism 100 is a material sowing system of an unmanned aerial vehicle, and the problem of blockage easily occurs in the material sowing process, so that the sowing mechanism 100 cannot work normally. However, in the prior art, in order to solve the problem of blockage of the sowing mechanism 100, a mechanism switch is usually arranged to clean the sowing mechanism 100 when the blockage occurs, so that the blockage problem is solved, but due to the structural arrangement, the whole sowing mechanism 100 cannot normally work, and the weight of the whole sowing mechanism 100 is increased due to the arrangement of other structures. The mechanism 100 of scattering that this embodiment provided can improve above-mentioned problem, the mechanism 100 of scattering that this embodiment provided directly sets up discharge opening 114 on defeated material casing 110, under the circumstances that mechanism 100 of scattering appears the material jam, can directly clear up the material of jam in defeated material casing 110 through discharge opening 114, can solve the jam problem of mechanism 100 of scattering under the circumstances that does not increase other structures, owing to set up discharge opening 114 and can be under the circumstances that the clearance material blockked up, lighten the weight of whole mechanism 100 of scattering.

In the present embodiment, the sowing mechanism 100 includes: the feeding assembly 120 and the feeding shell 110, the feeding assembly 120 is detachably installed in the feeding shell 110, and the feeding shell 110 is provided with a feeding port 112 and a discharging port 114; under the condition that the feeding assembly 120 is installed in the feeding shell 110, the feeding assembly 120 shields the discharge opening 114, so that the feeding opening 112 is not communicated with the discharge opening 114; the inlet port 112 is in communication with the discharge port 114 when the feeder assembly 120 is not installed in the feeder housing 110.

In this embodiment, when feeding assembly 120 is installed in feeding housing 110, feeding assembly 120 is blocked to discharge opening 114, and after entering feeding housing 110, the material can be conveyed to spreading assembly 130 by feeding assembly 120, and spread by spreading assembly 130.

After the sowing operation is completed, the whole sowing mechanism 100 needs to be cleaned, residual materials may be in the material box 140, the materials in the material box 140 need to be washed away or fished out in the cleaning process, the feeding assembly 120 is detached from the material conveying shell 110, the feeding port 112 is communicated with the discharging port 114, the residual materials in the material box 140 can directly fall out of the material conveying shell from the discharging port 114, the manual operation of picking out the materials from the two ends of the material conveying shell 110 is reduced, and the sowing mechanism 100 is convenient to clean.

Similarly, in the case of blockage of the spreading mechanism 100, when the feeding assembly 120 is detached from the feeding housing 110, the feeding port 112 is communicated with the discharging port 114, that is, the discharging port 114 is communicated with the inner cavity of the feeding housing 110, and the material blocked in the feeding housing 110 can be discharged through the discharging port 114, so that the problem of blockage of the spreading mechanism 100 can be solved.

Further, owing to seted up discharge opening 114 on defeated material casing 110, reduced defeated material casing 110's partial structure, make defeated material casing 110's weight reduce, when whole scattering mechanism 100 installs on unmanned aerial vehicle, can reduce whole scattering mechanism 100's weight to reduce unmanned aerial vehicle's load, improve unmanned aerial vehicle's load.

It should be noted that, in the present embodiment, in the case where the feeding assembly 120 is not installed in the feeding housing 110, the discharge opening 114 is exposed, the inner space of the feeding housing 110 is communicated with the outside through the discharge opening 114, that is, the discharge opening 114 is communicated with the inner space of the feeding housing 110, the feeding opening 112 is also communicated with the inner space of the feeding housing 110, and the feeding opening 112 is communicated with the discharge opening 114 through the inner space of the feeding housing 110.

That is, in the case where the feeding unit 120 is not installed in the feeding housing 110, the connection between the discharge opening 114 and the feeding opening 112 means that the discharge opening 114 is connected to the feeding opening 112 through the inner space of the feeding housing 110, and does not mean that the feeding opening 112 and the discharge opening 114 must be disposed correspondingly, nor that the feeding opening 112 and the discharge opening 114 must be disposed to overlap.

In this embodiment, the feeding assembly 120 includes a connecting housing 122 and a transmitting portion 124, the transmitting portion 124 is disposed inside the connecting housing 122, and the connecting housing 122 is detachably mounted in the feeding housing 110; under the condition that the connecting shell 122 is installed in the feeding shell 110, the connecting shell 122 shields the discharge opening 114, so that the feed opening 112 is not communicated with the discharge opening 114; in the condition where connecting housing 122 is not installed in feed delivery housing 110, feed inlet 112 communicates with discharge outlet 114.

In the present embodiment, the spreading mechanism 100 further includes a spreading assembly 130, and the conveying portion 124 is used for conveying the material into the spreading assembly 130 and spreading the material through the spreading assembly 130. When the connecting shell 122 is installed in the feeding shell 110, the connecting shell 122 closes the discharge opening 114, and after the material enters the feeding shell 110, the material can be conveyed to the material scattering assembly 130 under the action of the connecting shell 122, and the material can be scattered through the material scattering assembly 130. In the case of blockage of the sowing mechanism 100, the connecting shell 122 is detached from the feed delivery shell 110, and the feed inlet 112 is communicated with the discharge outlet 114, that is, the discharge outlet 114 is communicated with the inner cavity of the feed delivery shell 110, so that the material blocked in the feed delivery shell 110 can be discharged through the discharge outlet 114, thereby facilitating the cleaning of the sowing mechanism 100.

In this embodiment, in the case where the sowing mechanism 100 needs to be cleaned, the connecting casing 122 is directly detached from the feed delivery casing 110, so that the discharge opening 114 is exposed, and the material jammed in the feed delivery casing 110 can be directly discharged from the discharge opening 114. After the connecting housing 122 is removed, water can be sprayed into the feed delivery housing 110 for cleaning, thereby cleaning the sowing mechanism 100.

In the process of detaching the connecting housing 122, the components on the end surface 118 of the feed delivery housing 110 are detached to open one end of the feed delivery housing 110, and then the connecting housing 122 is detached from the opening on one end of the feed delivery housing 110 along the extending direction of the feed delivery housing 110. The assembly is simple, can realize the efficiency of quick clearance under the condition that the material blockked up, has improved whole unmanned aerial vehicle's operating efficiency.

In the present embodiment, the shape of connecting shell 122 is adapted to the shape of feed delivery shell 110. The connection housing 122 and the feed delivery housing 110 can be assembled, and the connection housing 122 is also provided in a cylindrical shape under the condition that the feed delivery housing 110 is cylindrical.

In addition, in order to form the feed delivery housing 110 in other shapes, the connecting housing 122 is also formed in other shapes. For example: when the feed delivery casing 110 is rectangular, the connecting casing 122 is also rectangular. When the feeding housing 110 is configured in a table shape, the feeding housing 110 is also configured in a table shape. It is sufficient to ensure that the shape of connecting housing 122 matches that of feed delivery housing 110.

Referring to fig. 3, in the present embodiment, the connecting casing 122 is provided with a connecting port 1221, and the connecting port 1221 is communicated with the feeding hole 112, so that the material can enter the connecting casing 122 through the feeding hole 112 and the connecting port 1221.

In this embodiment, the connection port 1221 is communicated with the feed port 112, and the material can enter the connection housing 122 through the feed port 112 and the connection port 1221, and the material entering the connection housing 122 enters the material scattering assembly 130 under the driving of the transmission part 124.

In this embodiment, the inlet 112 is adapted to the shape and size of the connection port 1221. The two are matched in shape and size.

Here, the fitting of the shapes of the feed port 112 and the connection port 1221 means that the shape of the connection port 1221 is the same as the shape of the feed port 112, that is, if the feed port 112 is rectangular, the connection port 1221 is also rectangular. If the feed opening 112 is circular, the connection opening 1221 is also circular, and if the feed opening 112 is triangular, the connection opening 1221 is also triangular. In short, the shape of the two components is matched.

In this embodiment, because the material needs to enter into inside the connecting shell 122 through the feeding port 112 and the connecting port 1221, in order to reduce the material to fall into the gap between the feeding shell 110 and the connecting shell 122, when setting up the size of the feeding port 112 and the connecting port 1221, the size of the connecting port 1221 should not be smaller than the size of the feeding port 112, that is, the size of the connecting port 1221 should be larger than or equal to the size of the feeding port 112, thereby ensuring that the material entering into the feeding port 112 can enter into the connecting shell 122 as completely as possible, reducing the situation that the material falls into the connecting shell 122 and the feeding shell 110, and thus reducing the risk of blockage.

It should be noted that, in the present embodiment, in the shapes and sizes of the connection port 1221 and the feeding port 112, it should be ensured that the projection of the feeding port 112 on the connection port 1221 can be completely within the connection port 1221, that is, the connection port 1221 can completely cover the feeding port 112, so as to ensure that the material entering the feeding port 112 can completely enter the connection housing 122 as far as possible, and reduce the situation that the material falls into the connection housing 122 and the material conveying housing 110, thereby reducing the risk of blockage.

In this embodiment, set up connector 1221 on connecting casing 122, reduced the partial quality of connecting casing 122, when whole mechanism 100 of scattering is installed on unmanned aerial vehicle, can reduce whole weight of scattering mechanism 100 to reduce unmanned aerial vehicle's load, improve unmanned aerial vehicle's load.

In this embodiment, when the entire distribution mechanism 100 is clogged, the connection housing 122 is detached from the feed delivery housing 110 to clean the material, and after the cleaning is completed, if a new operation is required, the connection housing 122 is reloaded into the feed delivery housing 110 to close the connection housing 122 to the discharge opening 114 and to connect the connection opening 1221 to the feed opening 112, thereby distributing the material.

In this embodiment, connecting housing 122 is an interference fit or clearance fit with feed delivery housing 110.

In this embodiment, the interference fit between the feeding housing 110 and the connecting housing 122 makes there be almost no gap therebetween, and in the process of conveying the material, the material can directly enter the connecting housing 122 through the connection port 1221 after entering the feeding port 112, thereby avoiding the blockage of the spreading mechanism 100 caused by the material entering the gap between the connecting housing 122 and the feeding housing 110.

It should be noted that, in this embodiment, connect casing 122 and defeated material casing 110 interference fit, but not limited to this, in the utility model discloses an in other embodiments, connect and can not adopt interference fit between casing 122 and the defeated material casing 110, adopt clearance fit can conveniently connect casing 122 and defeated material casing 110's assembly and dismantlement. If clearance fit is adopted between the connecting shell 122 and the material conveying shell 110, a certain clearance exists between the connecting shell 122 and the material conveying shell 110, and in order to prevent materials from falling into the clearance between the connecting shell 122 and the material conveying shell 110, a connecting plate can be arranged to connect the feeding port 112 and the connecting port 1221, so that a feeding channel communicated with the inner cavity of the connecting shell is formed between the feeding port 112 and the connecting port 1221. In addition, other structures can be provided to prevent the material from falling into the gap between the connecting shell 122 and the feeding shell 110.

Referring to fig. 4, in the present embodiment, a projection of the feeding hole 112 on the discharging hole 114 at least partially coincides with the discharging hole 114.

In the process of cleaning the spreading mechanism 100, after the connecting shell 122 is detached, the feed opening 112 is directly communicated with the discharge opening 114, so that the materials in the piled material box 140 can be quickly discharged out of the delivery shell 110 from the discharge opening 114, and the cleaning speed of the spreading mechanism 100 is improved.

In this embodiment, in the feeding process of the feeding port 112, if the feeding port 112 is blocked, after the connecting casing 122 is detached, the feeding port 112 is directly communicated with the discharging port 114, so that the material blocked at the feeding port 112 can be directly discharged from the discharging port 114, thereby reducing the risk of accumulation in the feeding casing 110 and improving the efficiency of material blockage cleaning.

Preferably, in the present embodiment, the projection of the feeding inlet 112 on the discharge opening 114 is totally coincident with the discharge opening 114, in other words, the feeding inlet 112 is smaller than the discharge opening 114, and the discharge opening 114 is relatively larger. The larger the discharge opening 114 is set, the faster the cleaning speed after the occurrence of clogging. Meanwhile, the larger the discharge opening 114 is, the lighter the weight of the feeding housing 110 is, the lighter the weight of the whole sowing mechanism 100 is, the smaller the load of the unmanned aerial vehicle is, and thus the load of the unmanned aerial vehicle is increased.

In this embodiment, the discharge port 114 is provided at the bottom of the feeder housing 110, and the feed port 112 is provided at the top of the feeder housing 110.

In this embodiment, set up feed inlet 112 in the top of defeated material casing 110, after the material entered into feed inlet 112, can rely on the weight of self to enter into to connecting inside casing 122, need not to set up other drive structure again and transmit the material to connecting inside casing 122, reduced the setting of components and parts, reduced unmanned aerial vehicle's load.

Similarly, by disposing the discharge opening 114 at the bottom of the feed delivery housing 110, the material can be discharged from the discharge opening 114 rapidly under the gravity of the material after the connecting housing 122 is removed during the cleaning of the scattering mechanism 100, thereby increasing the cleaning speed of the scattering mechanism 100.

In this embodiment, the feeding housing 110 has a side surface 116 and two end surfaces 118, the two end surfaces 118 are connected by the side surface 116, and the feeding port 112 and the discharging port 114 are disposed on the side surface 116.

In this embodiment, a discharge port 119 is disposed on the end surface 118 of the feeding housing 110, and is connected to the spreading assembly 130 through the discharge port 119, and after the material enters the feeding housing 110, the material enters the spreading assembly 130 through the discharge port 119 under the action of the transmission part 124, and is spread through the spreading assembly 130. In this embodiment, from the terminal surface 118 ejection of compact of defeated material casing 110, can make the material can be comparatively orderly get into to spill in the material subassembly 130, avoid the feed rate that appears from the bottom feeding of defeated material casing 110 too fast to lead to spilling the condition that material subassembly 130 appears blockking up, improved the effect of scattering of mechanism 100.

Generally, the feeding hole 112 is disposed at the top of the feeding housing 110, and if the discharging hole 119 is disposed at the bottom of the feeding housing 110, after the material enters the feeding housing 110 through the feeding hole 112, the material may be directly discharged from the discharging hole 119 under the action of gravity, and rapidly enter the scattering assembly 130, and is accumulated in the scattering assembly 130, so that the scattering assembly 130 is blocked. The material outlet 119 is arranged on the end face 118 of the material conveying shell 110, after the material enters the material conveying shell 110 through the material inlet 112, the material gradually enters the material scattering assembly 130 through the material outlet 119 of the end face 118 under the driving of the conveying part 124, so that the material can enter the material scattering assembly 130 at a constant speed, the blockage of the material in the material scattering assembly 130 is avoided, and the scattering effect of the scattering mechanism 100 is improved.

It will be readily appreciated that if the feed rate is too high, and the feed rate is relatively slow, material may accumulate in the feed housing 110. If the feed rate is relatively fast and the spill rate is relatively slow, it may result in material accumulation in the spill assembly 130.

Also, if the feeding speed is too slow and the spreading speed is too fast, the spreading assembly 130 may be rotated excessively, resulting in wear of the spreading assembly 130. If the feeding speed is too slow and the feeding speed is too fast, the transmission part 124 may be rotated excessively, resulting in wear of the transmission part 124.

Further, in order to reduce the accumulation of the material in the feed housing 110, the feeding speed of the conveyor 124 and the feeding speed of the material into the feed housing 110 may be set according to the spreading speed of the spreading assembly 130. The material spreading speed, the material feeding speed and the material feeding speed are matched with each other, so that excessive abrasion of the transmission part 124 and the material spreading assembly 130 can be reduced while materials are prevented from being accumulated in the material conveying shell 110 or the material spreading assembly 130, and the service lives of the transmission part 124 and the material spreading assembly 130 are prolonged.

In the present embodiment, the feeding housing 110 is cylindrical, wherein the end surfaces 118 refer to two planes at two ends of the feeding housing 110, the side surfaces 116 refer to arc surfaces of the feeding housing 110, and the top and bottom of the feeding housing 110 refer to the upper and lower sides of the feeding housing 110 in the working state of the whole scattering assembly.

In this embodiment, the connecting housing 122 has a transition port 1223, the feeding housing 110 is provided with a discharge port 119, the transition port 1223 and the discharge port 119 are at least partially communicated, and the material entering the connecting housing 122 can be discharged from the discharge port 119 by the transmission portion 124.

In this embodiment, the material outlet 119 is connected to the material spreading assembly 130, and after the material enters the interior of the connecting housing 122 through the material inlet 112 and the connecting port 1221, the material enters the material spreading assembly 130 through the transition port 1223 and the material outlet 119 under the driving of the transmission part 124, and the material is spread by the material spreading assembly 130.

In this embodiment, the transition port 1223 is in full communication with the discharge port 119. Since the size and shape of the transition port 1223 and the discharge port 119 are not fixed, a specific case where the transition port 1223 and the discharge port 119 are completely communicated will be exemplified.

In the first case, if the size of the transition port 1223 is larger than the size of the discharge port 119, the projection of the transition port 1223 on the discharge port 119 can completely cover the discharge port 119, and the transition port 1223 can completely cover the entire discharge port 119.

In the second case, if the size of the transition port 1223 is larger than the size of the discharge port 119, the projection of the discharge port 119 on the transition port 1223 can completely cover the transition port 1223, and the discharge port 119 can completely cover the entire transition port 1223.

In general, since the connecting housing 122 is disposed inside the feeding housing 110, in order to ensure the discharging speed, the size of the transition port 1223 is set to be larger, so as to ensure the flow rate of the material at the discharging port 119.

In the embodiment, connecting housing 122 is disposed inside feed delivery housing 110, the diameter of connecting housing 122 is slightly smaller than the diameter of feed delivery housing 110, transition port 1223 may have a diameter equal to the diameter of connecting housing 122, i.e., connecting housing 122 is not provided with an end portion, and connecting housing 122 is a hollow cylinder.

The working principle of the sowing mechanism 100 provided by the embodiment is as follows: in the present embodiment, after the material enters the connecting housing 122 from the feeding hole 112 and the connecting port 1221, the material is transported to the scattering assembly 130 through the discharging hole 119 by the driving of the transporting part 124, and is scattered by the scattering assembly 130. During cleaning of the mechanism 100, the connecting housing 122 is removed directly from the delivery housing 110 so that the discharge opening 114 is exposed and the material deposited in the bin 140 can be discharged directly from the discharge opening 114. After cleaning, if re-operation is required, the connecting shell 122 is re-loaded into the feeding shell 110, so that the connecting shell 122 blocks the discharge opening 114, and the connecting opening 1221 is communicated with the feed opening 112, thereby spreading the material.
