Referring to fig. 1 to 7, a rail 8 type blade picking device comprises a rail 8, a main frame 7, a traveling system and a plurality of picking mechanisms.

Wherein, referring to fig. 1, track 8 parallel arrangement is in the both sides of planting the ridge and extends along the direction of planting the ridge, and track 8 can extend to the end of planting the ridge to let the picking device can pass through each part of planting the ridge, avoid appearing picking the region that the device can't reach and also having mulberry 110, and need the manual work to pick.

Referring to fig. 1, the traveling system includes a traveling wheel 9 disposed at the bottom of the main frame 7 and a traveling power device 91 for driving the traveling wheel 9 to rotate. The main frame 7 spans across the planting ridges and is supported on the rails 8 at two sides through the travelling wheels 9, and the travelling wheels 9 can drive the main frame 7 to travel along the rails 8 after rotating. The main frame 7 spans across the planting ridges, so that the mulberry 110 can be prevented from obstructing the main frame 7 to walk. It will be appreciated that the dimensions of the road wheels 9 should be matched to the rails 8 to ensure that they can travel along the rails 8 and that the main frame 7 needs to be sufficiently high to exceed the height of the mulberry 110. The walking power device 91 can be a motor, and the motor rotates to drive the walking wheels 9 to rotate through the related transmission mechanism, so as to drive the main frame 7 to walk along the track 8. In one embodiment, the walking power device 91 is powered by an engine driving a hydraulic oil pump to rotate, and the main frame 7 moves back and forth on the rails 8 by controlling a hydraulic control valve to make a hydraulic motor driving the walking wheels 9.

Referring to fig. 1, the picking mechanisms are sequentially fixed on the main frame 7 at intervals and located between the rails 8 on the two sides, and the picking mechanisms also travel along with the travel of the main frame 7, so that the mulberry leaves 111 are picked while traveling. It will be appreciated that the spacing of the picking mechanisms, which may be arranged to provide spacing between the respective ridges of mulberry 110, ensures that the picking mechanisms are aligned with the ridges of mulberry 110 to provide accurate picking of the mulberry 110 between the two tracks 8. In one embodiment, the main frame 7 comprises a supporting portion 71, a top beam portion 72 and a mounting portion 73, two ends of the top beam portion 72 are respectively and fixedly connected with the supporting portions 71 at two sides to form an "Jiong" type structure, the bottom of the supporting portion 71 is provided with the travelling wheels 9, and the travelling wheels 9 are supported on the rails 8 at two sides by crossing the planting ridges and passing through the travelling wheels 9 through the "Jiong" type structure; the two ends of the mounting part 73 are connected with the supporting part 71, the picking mechanisms are fixed on the mounting part 73, the mounting part 73 is of a structure similar to a cross beam, and each picking mechanism is suspended and fixed, so that each picking mechanism can be driven to move together when the main frame 7 walks. The main frame 7 is a steel frame structure, which has sufficient bearing strength and sufficient space for installing other structures.

Preferably, referring to fig. 1, the rail 8 type blade picking device further comprises a lifting driving mechanism; the supporting part 71 is provided with a lifting chute 711 structure, two ends of the mounting part 73 are slidably mounted in the lifting chute 711 structure, and the lifting driving mechanism is used for driving the mounting part 73 to lift up and down and stay at a specified height, so that the height of the mounting part 73 can be changed through the lifting driving mechanism, the height of the picking mechanism is adjusted, the picking mechanism is suitable for mulberries 110 with different heights, and the universality is improved. Specifically, the lifting driving mechanism includes a telescopic brace 74, the telescopic brace 74 is longitudinally arranged, one end of the telescopic brace 74 is fixed to the supporting portion 71, and the other end of the telescopic brace is fixedly connected to the bottom surface of the mounting portion 73, the telescopic brace 74 may be a hydraulic brace, and is connected to a hydraulic pipeline of the walking power device 91, and the hydraulic brace is controlled to extend or retract through switching of a hydraulic control valve, so as to control lifting.

Wherein, with reference to fig. 2 to 7, the picking mechanism comprises a picking support 1, at least two winding mechanisms 21 mounted on said picking support 1 and a blade collection system 3. Wherein every two winding mechanisms 21 are oppositely arranged to form a group of picking parts 2 and a gap 22 for the planting clump (namely a ridge of mulberry 110) to pass through is formed between the two winding mechanisms. That is, one picking part 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 110 at both sides in the gap 22. 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. 2 to 5, 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 110 enters the gap 22, the picking surface 2111 can be attached to the side of the mulberry 110, it can be understood that the width of the gap 22 should be reasonably set, that is, the mulberry 110 can enter the gap, and the picking surface 2111 should contact with more mulberry leaves 111 as much as possible, and it can be understood that after the mulberry 110 enters the gap, the picking surfaces 2111 on both sides press and gather the original fluffy and outward-extending branches and leaves, and the branches and leaves cannot be broken due to the toughness of the branches and leaves. Here, since the winding and picking surface 2111 may be disposed parallel to the moving direction of the main frame 7, picking can be performed conveniently during the moving process without readjusting the direction.

The winding roller 212 is moved in a translational manner from bottom to top in the gap 22, and the rotation of the side close to the winding and picking surface 2111 is from top to bottom, so that a blade winding slot 213 is formed between the winding and picking 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 blade is brought into the blade winding slot 213 along with the rotation of the winding roller 212, the blade is clamped by the winding roller 212 and the winding and picking surface 2111 and moves downwards around the winding roller 212 from the top, so that the blade is 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 110 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. 2, 3 and 7, 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 put in a container or connected with other conveying mechanisms at the leaf outlet 311 and then conveyed out for storage. After picking, the leaves can be driven by the main frame 7 to move forward, and other leaves are picked continuously.

It can be understood that if a plurality of picking parts 2 are provided at the same time, a plurality of ridges of mulberry 110 can be picked at the same time, and the picking efficiency of mulberry leaves 111 is further improved.

Specifically, referring to fig. 4, 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 direction of rotation 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 this gap.

Referring to fig. 2, the blade picking mechanism of the invention further comprises 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. 6, a certain ring of the multi-stage belt transmission mechanism is rotated by using a clutch 41, 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 conveyor belt mechanism 211 and the roller 212 can be controlled without stopping the engine. Specifically, the blade picking mechanism further comprises a touch stop lever 5 located above the gap 22, the touch stop lever 5 comprises a lever body 51 arranged along the direction of the passage of the planting clump and a plurality of stop branches 52 extending from the lever 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 lever body 51 is connected with the clutch 41, and the other end is connected with the picking support 1 through an elastic resetting 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 part 2, and if the height of the mulberry 110 is too high, the mulberry may be vertically wound into the transmission link of the driving device 4, so that by the arrangement of the touch bar 5, if an excessively high branch contacts the stop branch 52 of the touch bar 5 and moves forward along with the main frame 7, the branch blocks the touch bar 5 from moving forward, and the touch bar 5 is pushed backward to a predetermined position, and at this position, the clutch 41 is disconnected from the transmission connection with the driving device 4, so that the excessively high branch is prevented from being caught by the transmission mechanism above, and causing equipment failure. When the main frame 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. 4, the winding roller 212 is provided with an annular groove 241 in scarf joint with the first transmission belt, 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 and picking surface 2111 and the side close to the winding roller 212 move from top to bottom in the gap.

In one embodiment, referring to fig. 2 and 3, several picking parts 2 are sequentially arranged in a direction perpendicular to the moving direction of the main frame 7, so that it is possible to pick up mulberry leaves 111 simultaneously for a plurality of ridges of mulberry trees 110. Considering that the height of the mulberry 110 may be greater than the length of the leaf picking conveyor belt 211, so as to avoid that the mulberry leaves 111 with partial height cannot be picked, in the present invention, at least two picking parts 2 are sequentially arranged along the moving direction of the main frame 7, and the two picking parts 2 have different heights and the projection parts on the vertical plane coincide, that is, the two picking parts 2 are used to pick the mulberry leaves 110 with different heights on the same ridge, thereby ensuring that the mulberry leaves 111 with each height of the mulberry 110 can be picked, and meanwhile, the projection parts coincide, so as to avoid the gap 22 between the two picking parts 2 in the height direction, and avoid the mulberry leaves 111 from being missed.

In one embodiment, referring to fig. 7, in order to facilitate the collection of the picked mulberry leaves 111, the blade collection system 3 further includes two blade conveyer belts 32 disposed closely, a blade conveyer passage 33 is formed between the two blade conveyer belts 32, an inlet end of the blade conveyer passage 33 is located at the leaf outlet end 311, one of the blade conveyer belts 32 forms a pressing conveyer section 321 in front of the inlet end, and a distance between the pressing conveyer section 321 and the leaf falling conveyer belt is gradually reduced along a conveying direction of the leaf falling conveyer belt. Through the structure, after the picked mulberry leaves 111 fall on the fallen leaves conveyer belt, the picked mulberry leaves 111 are driven by the fallen leaves conveyer belt to move towards the leaves outlet end 311, at the moment, the mulberry leaves 111 are naturally fallen 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 111 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 111 continuously reduce in volume and gradually become compact, and continuously advance to 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 picking bracket 1 and can synchronously move along with the movement of the leaf picking mechanism. In this embodiment, the blade conveying passage 33 is disposed upward, and the end of the blade conveying passage is located above, and a container or other conveying mechanism for collecting the mulberry leaves 111 can be placed 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.

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 110 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 portion 6 is provided with a first guide belt 61 arranged in a V shape, and at the V shape, the direction of the first guide belt 61 is from the gap 22 to the gap 22, so that when the branches and leaves of the mulberry 110 contact the first guide belt 61, the branches and leaves can be guided by the first guide belt 61 to enter the gap 22, and the branches and leaves are prevented from colliding with and rubbing against the first guide belt 61 and the leaf picking mechanism, so as to avoid the damage to the mulberry 110.

Preferably, the speed of the second guiding conveyor belt 62 is set to be faster than that of the first guiding conveyor belt 6, so that when one adjacent mulberry 110 sequentially comes from the first guiding conveyor belt 61 to the gap to contact with the second guiding conveyor belt 62, the mulberry 110 contacting with the second guiding conveyor belt 62 is accelerated to enter the gap 22 due to the speed difference, so as to be separated from the mulberry on the first guiding conveyor belt 61 by a certain distance, therefore, when the mulberry 111 is wound by the winding mechanism 21, the mulberry 110 can be separated to pick up the mulberry 111, and the mulberry 111 can be prevented from being stacked together and being too heavy to affect the normal leaf picking work.

In addition, referring to fig. 2, 3 and 6, the second guiding belts 62 are further disposed on two sides above the gap, the direction of the second guiding belts 62 is set back and forth, that is, when the mulberry 110 starts to enter the gap, the mulberry is further conveyed into the gap by being clamped by the two second guiding belts 62 in a matching manner, so as to further facilitate the mulberry 110 to enter the gap, and improve the efficiency, wherein the gap 22 between the second guiding belts 62 on the two sides is smaller than the minimum distance between the two first guiding belts 61, so as to bend the mulberry 110, thereby obtaining a larger friction force between the second guiding belts 62 and the mulberry 110 in the gap, and the clamping is tighter and more stable, and ensuring better mulberry leaf winding 111.
