It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The same reference numbers will be used throughout the drawings to refer to the same or like parts.

It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Further, the description of the upper, lower, left, right, etc. used in the present invention is only with respect to the positional relationship of the respective components of the present invention with respect to each other in the drawings.

Referring to fig. 1 to 7, a blade picking mechanism for mounting on a moving mechanism 7 comprises a frame 1, at least two winding mechanisms 21 mounted on the frame 1 and a blade collection system 3.

In the conventional mulberry 8 orchard, the mulberry 8 is planted in the ridge, so that the ridge of the mulberry 8 can be picked up during picking, and the picking can be started from one end along the ridge of the mulberry and continuously advances to the other end. In the scheme, the blade picking mechanism is arranged on the moving mechanism 7, and the moving mechanism 7 continuously moves forward along the direction of the mulberry ridge, so that the blade picking mechanism is driven to pick.

Referring to fig. 1 to 4, two winding mechanisms 21 are oppositely arranged to form a group of picking parts 2, and a gap 22 for the passage of the planting clump (i.e. a ridge of mulberry 8) is formed between the two winding mechanisms. That is, one picking section 2 has one gap 22 and has two winding mechanisms 21, and the two winding mechanisms 21 can simultaneously pick up the leaves of the mulberry 8 in the gap 22 at the same time. Each winding mechanism 21 comprises a leaf picking conveyor belt mechanism 211 arranged longitudinally and a winding roller 212 rotating and circularly moving around the leaf picking conveyor belt mechanism 211, namely, the winding roller 212 rotates around the axis of the winding roller, and also circularly rotates around the driving belt of the leaf picking conveyor belt mechanism 211, and understandably, the rotating track of the winding roller 212 is in a shape of a long circular hole.

Referring to fig. 4, one side of the conveyor belt facing the gap 22 is a picking surface 2111, the picking surface 2111 moves from top to bottom, when the mulberry 8 enters the gap 22, the picking surface 2111 can be attached to the side of the mulberry 8, it can be understood that the width of the gap 22 should be reasonably set, that is, the mulberry 8 can enter the gap, and the picking surface 2111 should contact with more mulberry leaves 81 as much as possible, and it can be understood that after the mulberry 8 enters the gap, the picking surfaces 2111 on both sides squeeze and gather the originally fluffy and outward-extending branches and leaves, and the branches and leaves cannot be broken due to the toughness of the branches and leaves. In this case, since the picking surface 2111 may be disposed parallel to the moving direction of the moving mechanism 7, picking can be performed conveniently during the moving process without adjusting the direction again.

Referring to fig. 4, the winding roller 212 translates from bottom to top in the gap 22 and rotates from top to bottom on a side near the winding/unwinding surface 2111, forming a blade winding gap 213 between the winding/unwinding surface 2111 and the winding roller 212. Since the rotation of the winding roller 212 on the side close to the winding and picking surface 2111 moves from top to bottom, and the blades are brought into the blade winding slot 213 along with the rotation of the winding roller 212, the blades are clamped by the winding roller 212 and the winding and picking surface 2111 and move downwards around the winding roller 212 from the top, so that the blades are pulled to separate branches, and the pulling and the separation mode is the same as the manual picking mode, and the damage to the mulberry tree 8 is small. In addition, the winding roller 212 rotates to wind the leaves, and also circularly moves around the leaf picking conveyor belt mechanism 211, and the winding roller 212 moves in the gap 22 in a horizontal mode from bottom to top, namely, the winding roller starts to wind the leaves from the bottom and continuously rises, so that the leaves are sequentially picked from bottom to top, the leaves are fully picked, and the omission of too many leaves is avoided. After the winding roller 212 reaches the highest point, the winding roller can rotate to the back of the leaf picking conveyor belt mechanism 211 and continuously descend, the leaves are not wound in the descending process, and after the winding roller descends to the lowest point, the leaves enter the gap again, are wound and ascend, so that the continuous picking of the leaves is realized, the continuous work is realized, and the picking efficiency is improved.

With reference to fig. 1 and 6, the blade collecting system 3 includes a fallen leaf conveyor mechanism 31 located below the leaf picking conveyor mechanism 211, and the end of the fallen leaf conveyor is a leaf outlet 311. The picked leaves pass through the winding roller 212 and then fall down onto the fallen leaves conveyor 31 and are discharged through the fallen leaves conveyor 31, and the leaves can be conveyed out and stored by placing a container at the leaf outlet 311 or connecting with other conveying mechanisms. After picking, the leaves can be driven by the moving mechanism 7 to move forward, and other leaves are picked continuously.

It can be understood that if a plurality of groups of picking parts 2 are arranged at the same time, a plurality of ridges of mulberry trees 8 can be picked at the same time, and the picking efficiency of the mulberry leaves 81 is further improved.

Specifically, referring to fig. 2 and 3, in order to realize that the winding roller 212 circularly rotates around the leaf picking and conveying mechanism 211, the winding mechanism 21 further includes chain wheel 231 mechanisms 23 respectively located at two sides of the leaf picking and conveying mechanism 211, and the chain wheel 231 mechanisms 23 include a plurality of chain wheels 231 and chain belts 232; each chain wheel 231 is rotatably connected with the roller at the two ends of the leaf picking conveying belt mechanism 211, the chain belt 232 is arranged on the upper chain wheel 231 and the lower chain wheel 231, and the two ends of the winding roller 212 are respectively coupled with the chain belts 232 at the two sides. Namely, by arranging the chain wheel 231 with the same rotation axis outside the leaf picking and conveying belt mechanism 211 and installing the chain belt 232, when the chain belt 232 rotates, the winding roller 212 can be driven to realize the circular rotation. It should be noted that the rotation direction of the chain belt 232 is opposite to the direction of the belt of the leaf picking belt mechanism 211, so as to ensure that the winding picking surface 2111 moves downward and the winding roller 212 moves upward in the gap.

With reference to fig. 1 to 3, the blade picking mechanism of the present invention further includes a driving device 4, a driving roller 2112 and a driven roller are arranged in the blade picking conveyor belt mechanism 211, and the driving roller 2112 and the driven roller are driven by a first conveyor belt 2114; the driving roller 2112 is provided with a first gear 2115, the chain wheel 231 is provided with a second gear 233, the first gear 2115 is meshed with the second gear 233, and the driving roller 2112 is in transmission connection with the driving device 4. The driving device 4 drives the driving roller 2112 to drive the leaf picking belt mechanism 211 to rotate, and the driving roller 2112 drives the chain wheel 231 to rotate through a gear engagement mode, so that the moving directions of the winding and picking surface 2111 and the winding roller 212 are opposite in the gap. In one embodiment, the driving device 4 includes a motor, a speed reducer, and a multi-stage belt transmission mechanism, and the multi-stage belt transmission mechanism amplifies the torque of the motor and drives the multi-stage belt transmission mechanism, and is connected to the driving roller 2112 to drive the driving roller 2112.

In a preferred embodiment, referring to fig. 2 and 3, a clutch 41 is used to rotate a certain ring in the multi-stage belt transmission mechanism, and whether the power is finally transmitted to the driving roller 2112 can be controlled by the clutch 41, so that the starting or stopping of the leaf picking action of the leaf picking and conveying belt mechanism 211 and the roller 212 can be controlled without stopping the engine. Specifically, the blade picking mechanism of the present invention further comprises a touch blocking rod 5 located above the gap 22, the touch blocking rod 5 comprises a rod body 51 arranged along the direction of the passage of the planting clump and a plurality of blocking branches 52 extending from the rod body 51 to the inside of the gap 22, the driving device 4 is in transmission connection with the driving roller 2112 through a clutch 41, one end of the rod body 51 is connected with the clutch 41, and the other end is connected with the bracket 1 through an elastic reset piece 53; when the rod 51 is pushed to a predetermined position, the clutch 41 is disconnected from the driving device 4, and when the rod 51 returns to the initial position under the action of the return spring, the clutch 41 is connected with the driving device 4 in a transmission manner. In this embodiment, the driving device 4 is installed above the picking unit 2, and if the height of the mulberry 8 is too high, the mulberry may be vertically wound into the transmission link of the driving device 4, so that, by the installation of the touch bar 5, if an excessively high branch contacts the branch 52 of the touch bar 5 and moves forward along with the moving mechanism 7, the branch blocks the touch bar 5 from moving forward, thereby pushing the touch bar 5 backward to a predetermined position, and at this position, the clutch 41 is disconnected from the transmission connection with the driving device 4, thereby preventing the excessively high branch from being caught by the transmission mechanism above and causing equipment failure. When the moving mechanism 7 continues to advance and the rod body 51 returns to the initial position under the action of the return spring after separating from the excessively high branches, the clutch 41 is in transmission connection with the driving device 4, so that the picking operation can be continued.

In order to realize the rotation of the winding roller 212, referring to fig. 2 and 3, an annular groove 241 in engagement with the first transmission belt is arranged on the winding roller 212, and the winding roller 212 is driven to rotate by the first transmission belt, so that the rotation directions of the winding roller 212 and the leaf picking transmission belt mechanism 211 are opposite, and the winding picking surface 2111 and the surface of the winding roller 212 close to each other move from top to bottom in the gap.

In one embodiment, referring to fig. 1 and 2, several picking parts 2 are sequentially arranged in a direction perpendicular to the moving direction of the moving mechanism 7, so that it is possible to pick up mulberry leaves 81 simultaneously for a plurality of ridges of mulberry trees 8. In the invention, at least two picking parts 2 are sequentially arranged in the moving direction of the moving mechanism 7, the two picking parts 2 are different in height and the projection parts on the vertical plate planes are overlapped, namely the two picking parts 2 are adopted to pick the mulberry leaves 81 on the same ridge, so that the mulberry leaves 81 at each height of the mulberry 8 can be picked, and the overlapped arrangement of the projection parts avoids a gap 22 between the two picking parts 2 in the height direction and avoids the mulberry leaves 81 from being picked.

In one embodiment, referring to fig. 1 and 7, in order to facilitate the collection of the picked mulberry leaves 81, the leaf collecting system 3 further includes two closely arranged leaf conveyer belts 32, a leaf conveyer passage 33 is formed between the two leaf conveyer belts 32, an inlet end of the leaf conveyer passage 33 is located at the leaf outlet end 311, one of the leaf conveyer belts 32 forms a pressing conveyer section 321 in front of the inlet end, and the distance between the pressing conveyer section 321 and the leaf falling conveyer belt is gradually reduced along the conveying direction of the leaf falling conveyer belt. Through the structure, after the picked mulberry leaves 81 fall on the fallen leaves conveyer belt, the picked mulberry leaves 81 are driven by the fallen leaves conveyer belt to move towards the leaves outlet end 311, at the moment, the mulberry leaves 81 naturally fall and are fluffy, when the mulberry leaves reach the extrusion conveying section 321, the conveying direction of the extrusion conveying section 321 is towards the leaves outlet end 311, the fluffy mulberry leaves 81 continue to advance, along with the gradual reduction of the distance between the extrusion conveying section 321 and the fallen leaves conveyer belt, the fluffy mulberry leaves 81 continuously reduce in volume and gradually become compact, and continuously advance to reach the inlet end of the leaf conveying channel 33, and then are carried by the two leaf conveyer belts 32, finally reach the tail end of the leaf conveying channel 33 and are discharged. Wherein, the blade conveyer belt 32 and the fallen leaves conveyer belt are both arranged on the bracket and can synchronously move along with the movement of the leaf picking mechanism. In this embodiment, the blade conveying path 33 is disposed upward, and the end of the blade conveying path is located above, and a container or other conveying mechanism for collecting the mulberry leaves 81 can be disposed above. In one embodiment, the power of the fallen leaf conveyor belt and the blade conveyor belt 32 is also supplied from the driving device 4, and the power transmission is realized by adopting a belt transmission mechanism, so that only one power mechanism is required and the whole blade picking mechanism can be driven to work. Of course, the power mechanisms of the respective belts may be separated and separately provided.

Preferably, referring to fig. 1 to 3, in order to facilitate the entry of the mulberry 8 into the gap for picking up the mulberry leaves 81, the blade picking mechanism of the present invention further comprises a guide part 6 located in front of the gap 22, the guide part 6 having a V shape. In one embodiment, the guiding portions 6 are provided in front of both upper and lower ends of the winding mechanism 21, so that the fluffy and wide mulberry trees 8 can be guided and gathered into the gap 22 by the V-shaped structure to be picked by the picking surface 2111 and the winding roller 212. The guiding part 6 can be formed into a V shape by the bevel edges of two triangular frames, and can also be formed into a V shape by a conveyor belt mechanism. Preferably, the guide part 6 is provided with guide belts 61 arranged in a V shape, and at the V shape, the direction of the guide belts 61 is from the outside of the gap 22 to the inside of the gap 22, so that when the branches and leaves of the mulberry 8 contact the guide belts 61, the branches and leaves can be guided by the guide belts 61 to enter the gap 22, and the branches and leaves are prevented from colliding and rubbing with the guide belts 61 and the leaf picking mechanism to cause damage to the mulberry 8.

In addition, the second guide conveyor belts 62 are further arranged on two sides above the gap 22, the conveying directions of the second guide conveyor belts 62 are arranged in the front-back direction, namely when the mulberries 8 start to enter the gap, the mulberries 8 can be clamped by the two second guide conveyor belts 62 in a matching manner to continue conveying into the gap 22, the mulberries 8 can further conveniently enter the gap 22, and the efficiency is improved. Wherein, the mutual clearance of the second guiding transmission belt 62 of both sides will be less than two first guiding transmission belt 61 minimum distances, the purpose is the curved mulberry strip of top to can make in the gap 22 and obtain bigger frictional force between second guiding transmission belt 62 and the mulberry 8, press from both sides tighter, more stable, ensure that the coiling mulberry leaf 81 goes on better.

Preferably, the speed of the second guiding transmission belt 62 is set to be faster than that of the first guiding transmission belt 6, so that when one adjacent mulberry 8 comes into the gap from the first guiding transmission belt 61 in sequence and contacts with the second guiding transmission belt 62, due to the speed difference, the mulberry 8 is accelerated to enter the gap 22 after contacting with the second guiding transmission belt 62, so as to be separated from the mulberry on the first guiding transmission belt 61 by a certain distance, therefore, when the mulberry 81 is wound by the winding mechanism 21, the mulberry 8 can be separated to pick up the mulberry 81, and the mulberry 81 can be prevented from being piled together and too thick to affect the normal leaf picking work.

The invention also provides a picking device, which comprises a moving mechanism 7 and the blade picking mechanism, wherein the moving mechanism 7 can drive the blade picking mechanism to move along mulberry ridges, so that mulberry leaves 81 are picked gradually from mulberry trees 8 on the ridges.
