Description

Device and method for picking fruits and pruning branches and leaves

Technical Field

The present invention relates to a device and a method for picking fruits and pruning branches and leaves, in particular to the harvesting similar to round fruits.

Technical Field

With the progress of society, the agriculture develops rapidly, and the income level of fruit growers is greatly improved in a high-yield orchard. However, when picking fruits, fruit growers often adopt a traditional manual picking mode, which not only has low picking efficiency and large labor intensity, but also has certain potential safety hazard. Modern agriculture continuously develops towards mechanization, and after the 80 th century in 20 th, large orchard picking is developed from manual picking by using scissors to large mechanical device picking, but as orchard in China is mainly subjected to decentralized cultivation and household management, modern orchards which are really centralized and uniformly managed are few. Meanwhile, most automatic fruit picking machines have high cost, complicated operation, high additional consumption (such as power consumption), low technical quality of fruit growers, small production scale and the like, the mechanized automation degree of the orchard is generally low, and the automatic picking tools are not popularized in small-scale orchards managed by households. The design of the synergistic fruit picker which is convenient to operate and low in cost on the premise of ensuring the personal safety of fruit growers is of great significance.

The development of fruit pickers has been a long history. The fruit picker in the market at present is various in type, and the theory of operation changes according to picking the object, and it is mainly two types to have manual and electrodynamic type, and whether easily hang branch and leaf, shake near fruit, whether pass branch and leaf clearance easily, whether the hand is easy some aspects such as tired consider still not enough, and is relatively poor to the adaptability of variety job requirement.

At present, most of manual fruit pickers in the market are in a pulling type and a common shearing type, but the two types of fruit pickers still have some problems.

The pulling type fruit picker consists of a three-jaw picking head, a rod body and a handle at the lower part of the rod body, wherein the jaw center of the three-jaw picking head is coated with rubber. Each claw is internally provided with a transmission steel wire which is connected with the handle through the inside of the rod body. When the fruit picking device is used, the picking head supports fruits from the bottom, the handle is kneaded, so that the transmission steel wire is tensioned, the claw can firmly grab the fruits, and the fruits are picked by pulling downwards with force. However, the fruit picking mode is easy to shake off nearby fruits, is not easy to penetrate through gaps between branches and leaves, is easy to damage the integrity of the fruits, is labor-consuming when being pulled, and has high requirements on the size and hardness of the picked fruits and small audience range. See chinese patent application CN 108076825A.

The picking head part of the common shearing type fruit picker is composed of a shearing head, a rod body and a handle at the lower part of the rod body, wherein the shearing direction of the shearing head is consistent with the kneading direction of the handle. The main branches can only be cut under the limitation of a force application mode during picking, and subsequent fine branch removing work is needed after the picking work is finished, so that heavier secondary work is brought. If the secondary labor is saved, the fine picking is directly carried out during picking, which is laborious. See chinese patent application CN 206866079.

The direction of mediating of the handle of this patent is picked and branch and leaf trimming means is the vertical relation basically with the shearing direction of scissors, and the angle of scissors head when shearing accords with the growth characteristics that fruit received gravity to hang down to the in-process that makes the shearing is more laborsaving. The scissor head is designed only aiming at the fruit handle, has small volume and is easy to pass through the gaps between branches and leaves for shearing. Buffering storage device can not only solve and cut back fruit and deposit the problem, can drop the process to fruit moreover and play the cushioning effect, has avoided pounding the fruit phenomenon. Its easy operation, the security is high, and the practicality is strong, can effectively help the fruit grower to accomplish fruit picking work, simultaneously because the shearing force is sufficient, can prune the branch and leaf of fruit tree simultaneously.

Examples of the invention

The device of the invention consists of a shearing mechanism, a connecting rod, a handle mechanism, a wire tightening mechanism and an angle changing mechanism. The shearing mechanism breaks through the traditional scissor mode, blades of the scissors and the connecting rod form a right angle under the general condition, the shearing mechanism is composed of two blades, a rotating knife arm, a fixed knife arm and a pull rod, and the blades are sheared by pulling the pull rod. A mesh bag is arranged below the blade, so that the fruit can be prevented from being broken. The connecting rod comprises shell and inside rope, and the rope drives the motion of pull rod through connecting rotatory tool arm and twist grip. The handle mechanism comprises fixed handle, twist grip, lock plate and boss, and wherein twist grip's effect drives wire rope and realizes the rotary motion of movable blade, and the effect of lock plate is that the device does not use, closes the tool bit, prevents to injure the user. The wire tightening mechanism can ensure that the steel wire rope is tightened to obtain larger shearing force, and the nut on the knob pressurizes the ratchet wheel during wire tightening, so that the inner ring of the ratchet wheel and the screw rod are driven to rotate under the action of the friction force, and the purpose of wire tightening is achieved. The principle of the angle-variable mechanism is that the ejector rod is driven to move by rotating the angle-variable cylindrical cam, so that the included angle between the fixed cutter arm and the connecting rod is changed, and the change of the shearing angle is realized.

Referring to fig. 1 of the present invention, the handle mechanism includes a fixed handle 1 disposed at a lower end of a connecting rod 10 and a rotating handle 2 hinged to a front end of the fixed handle 1 through a pin shaft, and the rotating handle 2 can rotate around a rotation axis a with respect to the fixed handle. Axis a referring to fig. 1, axis a is shown in fig. 1 as being perpendicular to the direction of the page. The front end of the fixed handle 1 is provided with a sleeve 8 for installing a connecting rod 10, so that the handle mechanism is sleeved at the lower end of the connecting rod 10 for controlling the shearing mechanism, a screw rod at the front end of the rotating handle 2 is wound with a flexible rope 7 which penetrates through the connecting rod 10 and is connected with a rotating cutter arm 13, and the flexible rope can be a steel wire rope or other flexible ropes basically without elasticity, such as a carbon fiber rope. When the user grips the handle and presses the rotating handle toward the fixed handle, the rotating handle 2 rotates about the axis a, thereby pulling the flexible cord, which pulls the rotary cutter arm 13 to rotate. When the rotary knife arm 13 rotates, the pull rod 16 is driven to move, so that the movable knife 15 rotates, and the effect of cutting the plant stalk part is achieved by rotating the rotary handle 2. The axis of rotation of the movable blade 15 is B, which is seen in fig. 1, wherein axis a is substantially perpendicular to axis B.

The buffer storage device 11 in the invention can be a multi-layer string bag structure, for example, comprising a first layer and a second layer of net buffer structure; flexible film cushioning structures that may also include a first stage and a second stage; through buffering step by step, can guarantee that sufficient buffering occasionally of fruit whereabouts reduces the fruit and damages.

The invention is designed with a wire tightening mechanism, when the angle of the shearing mechanism relative to the connecting rod changes, the flexible rope can be loosened and needs to be tensioned to ensure larger shearing force. As shown in FIG. 1, a wire tensioning mechanism, in which a knob 4 is located, is mounted on the twist handle 2 to control the tension of the flexible cord.

Fig. 2 shows a schematic view of a locking plate for a handle mechanism. The locking plate 4 has a hole 41 through which a bolt or other fastening means can rotatably secure the locking plate 4 to the swing handle. The bore 41 is preferably a counterbore. The locking piece 4 has a fixing groove 42. When the rotating handle 2 needs to be locked, the rotating handle 2 is held tightly, and the locking sheet 4 is rotated to enable the fixing groove 42 to be clamped on the boss 3 of the fixing handle 1; due to the elastic action of the spring 5, the rotary handle is locked by the fixing groove 42 and does not rotate relative to the fixing handle, thereby ensuring that the movable blade is kept in a safe position.

Referring to fig. 1 and 3, fig. 3 is a schematic view as viewed in the direction F-F of fig. 1. In fig. 1 and 3, the shearing mechanism comprises a rotary cutter arm 13, the rotary cutter arm 13 is hinged with a fixed cutter arm 12, the rotary cutter arm 13 can rotate by pulling a steel wire 7, and a compression spring 14 is strung between the rotary cutter arm 13 and the fixed cutter arm 12 for resetting. Fig. 3 shows that the cutting mechanism further includes a pull rod 16 and a pair of blades, a fixed blade 17 and a movable blade 15, respectively, and the pull rod 16 is connected to the rotary blade arm 13 at one end and to the movable blade 15 at the other end, and when the rotary blade arm 13 is pulled to rotate by the flexible string 7, the movable blade 15 is rotated. When the shearing action is realized once, the hand stops applying force, and the compression spring 14 applies force to the rotary cutter arm 13 to enable the shearing blade to return to the original position. Fig. 4 is a structural view of the pull rod 16.

The movable blade of the X-shaped scissors is shorter than the blade of the normal X-shaped scissors, and the part of the non-cutting arm of the movable blade only needs to exceed the hinge point of the movable blade and the fixed blade; the tie bar is arranged at the end part of the movable blade non-shearing arm, the movement of the tie bar is not the rotating movement around the rotating axis of the movable blade, but the tie bar rotates around the axis of the rotating cutter arm 13, and the power is transmitted to the movable blade by using the tie bar, so that the non-shearing edge part of the movable blade does not rotate in a large radius when shearing is carried out, and therefore, the tie bar and the non-shearing arm of the movable blade do not interfere with other objects except the object to be picked or sheared, the labor intensity is reduced, and the other objects are prevented from being damaged.

Refer to fig. 1, 5, 6; the right side in fig. 5 is a schematic view of the variable angle adjustment cam arranged above the handle mechanism. The cylindrical cam 9 and the push rod 19 jointly form an angle-changing mechanism, and the cylindrical cam is used for converting the rotary motion into the vertical linear motion of the push rod 19. The cylindrical cam 9 can rotate relative to the connecting rod but does not axially displace; the cylindrical cam 9 is hollow and has a spiral groove on its side. Fig. 6 is a schematic view of the ejector pin. The ejector rod 19 is substantially L-shaped; the width of the short side 191 of the jack 19 is substantially the same as the inner diameter of the cylindrical cam 9, and the short side 191 is fitted in the straight groove of the connecting rod 10 and the spiral groove of the cylindrical cam 9. The long side 192 of the ejector pin 19 passes through the connecting rod 10, and the hole at the top thereof is slidably connected to the groove 20 at the lower end of the fixed knife arm 12 by a pin. After the cylindrical cam 9 is rotated, the short side 191 does not rotate relative to the connecting rod, so that the spiral groove on the cylindrical cam 9 drives the short side 191 to displace axially relative to the cylindrical cam, the short side 191 drives the long side 192 to displace axially relative to the connecting rod 10, the long side 192 slides relative to the fixed cutter arm 12 through a pin and drives the free end of the fixed cutter arm 12 to displace, and the other end of the fixed cutter arm 12 is hinged to the connecting rod 10, so that the included angle between the fixed cutter arm 12 and the connecting rod 10 can be changed under the pushing of the long side 192 of the ejector rod 19.

The left side of fig. 5 shows a schematic view of the fixed knife arm 12 and the connecting rod 10 after the included angle is changed (relative to the included angle in fig. 1).

Referring to fig. 7, since the angle between the fixed knife arm 12 and the connecting rod 10 is changed in the present invention, the tension of the flexible rope needs to be adjusted. The tension adjusting device comprises a knob 6, a nut 62, a perforated screw 61, two washers 63, a pin 64 and ratchet mechanisms 65, 66.

After the included angle between the fixed knife arm 12 and the connecting rod 10 is adjusted by using the angle changing device so as to determine the posture positions of the fixed blade and the movable blade, the knob 6 is rotated clockwise, the nut 62 fixedly connected with the knob tightly presses the ratchet inner ring 65 through the gasket 63, friction force is generated between the ratchet inner ring 65 and the nut 62, and the friction force between the ratchet inner ring and the nut is larger when the nut 62 moves leftwards; since the screw 61 is screwed into the thread of the nut 62, when sufficient rotational force is applied to the knob 6, the nut 62, the knob 6, the inner ratchet ring 65, the screw 61, and the washer 63 will rotate integrally with respect to the outer ratchet ring 66, the outer ratchet ring 66 is fixed to the rotating handle 2, and the screw 61 rotates to pull the flexible cord 7, thereby providing the necessary tension to the flexible cord 7.

The inner ratchet ring can freely rotate relative to the outer ratchet ring in the clockwise direction, but can not freely rotate in the anticlockwise direction. When the tension of the flexible rope 7 is proper, the knob 6 stops rotating. At this time, due to the self-locking capability of the threads, sufficient friction force is kept between the knob 6 and the nut 62 and the inner ratchet ring 65, so that relative looseness cannot occur, and meanwhile due to the counterclockwise locking effect of the inner ratchet ring relative to the outer ratchet ring, the flexible rope can always keep sufficient tension force, so that looseness cannot occur.

In fig. 7, the knob, the nut, the winding direction of the flexible cord on the screw, and the unidirectional rotation direction of the ratchets 65, 66 can also be reversed from those described above, so long as the nut does not undesirably rotate after the knob 6 is tightened, thereby reducing the tension of the flexible cord.

When the flexible rope is loosened, the knob 6 is rotated anticlockwise, the knob 6 drives the nut 62 to rotate rightwards until the nut abuts against the pin 64, and at the moment, the nut 62 is loosened with the gasket 63 and the ratchet inner ring 65, and no larger friction force exists any more. Continuing to rotate the knob 6 counterclockwise, a large friction force is generated between the nut 62 and the pin 64, which in turn drives the screw 61 to rotate counterclockwise, and at this time, the flexible rope is loosened. The inner bore of the ratchet inner ring 65 is larger than the major diameter of the screw 61, and at this time, the counterclockwise rotation of the screw is not associated with the ratchet.

Fig. 8 shows the angle of the blade for cutting plant stalks relative to the stalks according to the present invention. In fig. 8, 101 is the fruit of the plant to be picked, and 102 is the stem of the plant. As can be seen from fig. 8, the adjusting blade is substantially perpendicular to the stem, so that the area of the plant to be cut can be reduced as much as possible, the plant stems remaining on the fruits can be reduced, sharp plant stems cannot be left on the fruits, the fruits which are picked are prevented from being damaged by the remaining plant stems, and the fruits are prevented from being secondarily trimmed.

Fig. 9 shows the shearing angle of the conventional shearing device relative to the stalk. In fig. 9, 101 is the fruit of the plant to be picked, and 102 is the stem of the plant. The shearing blade is in a small acute angle relative to the stem, so that long stems are inevitably left, and the stems have a sharp angle, so that other picked fruits are damaged; meanwhile, the shearing blade is acute-angled relative to the stem, so that the shearing area is large, picking personnel need to pay more labor, and the labor intensity is high.

According to the technical scheme, the angle of the blade relative to the fruit stem can be adjusted, so that when fruits at a higher position are picked, sharp and longer plant stems cannot be left in the picked fruits, the picked plant fruits cannot be damaged, the labor intensity is low, and meanwhile, the fruits do not need to be pruned for the second time.

The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments and is not intended to limit the practice of the invention to these embodiments. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
