Description

Technical Field

[0001] The invention relates to the field of fruit picking, in particular to a multifunctional handheld picker for harvesting navel oranges. Background Art

[0002] After the navel oranges are ripe, harvesters are needed to pick them. In the prior art, harvesters usually cut the navel oranges from the tree with scissors. To prevent the navel oranges from falling to the ground, the harvesters need to hold the navel oranges with their other hand before cutting, and throw the navel oranges into a collection box for collection after cutting. However, some navel oranges grow in places where branches and leaves are lush, so the harvesters need to push the branches or leaves aside before they can touch the navel oranges. For some navel oranges that are in high places, the harvesters need to pull down the branches before they can cut the navel oranges, resulting in the harvesters being unable to fix the navel oranges in time, so that the navel oranges are likely to fall to the ground.

[0020] The clamping jaw 5 is configured to be curved, so that the clamping jaw 5 is more closely fitted to the spherical shape of the navel orange, thereby facilitating the clamping jaw 5 to clamp the navel orange.

[0021] A flexible anti-slip cover is provided on the surface of the clamping jaw 5 to increase the friction between the clamping jaw 5 and the navel orange, thereby preventing the navel orange from falling out of the clamping jaw 5 .

[0022] An arc-shaped protective shell 1003 is provided in the area where the gripping rod 1 is gripped, and the protective shell 1003 isolates the connecting rod Ⅰ4001 from the outside world to prevent the connecting rod Ⅰ4001 from contacting the hands of the picking workers when moving, thereby improving the safety of use. The arc shape fits the shape of the palm when gripping better, thereby improving the comfort of use.

[0023] The height-increasing component includes a support rod 301, a net bag 302, a storage cabin 303, a data connection port 305 and a fixed cover 306; the support rod 301 is connected to the net bag 302, through which the navel oranges picked from a high place are temporarily stored; the support rod 301 is connected to the storage cabin 303; the storage cabin 303 is fixedly connected to the data connection port 305, and the support rod 301 is provided with a control button II 30101, and the control button II 30101 is electrically connected to the data connection port 305; the storage cabin 303 is snapped with the fixed cover 306; and a plug electrically connected to the data connection port 305 is provided at the bottom of the holding rod 1.

[0024] It also includes a motor II 304; the support rod 301 is fixedly connected to the motor II 304, and the output shaft of the motor II 304 is fixedly connected to the storage cabin 303; and the support rod 301 is provided with two control buttons III 30102, and the control buttons III 30102 are electrically connected to the motor II 304.

[0025] It also includes an extrusion plate Ⅰ201; an extrusion plate Ⅰ201 is fixedly connected to the lower side of the shear piece Ⅰ2 and the shear piece Ⅱ3, and the extrusion plate Ⅰ201 connected to the shear piece Ⅰ2 is provided with a plurality of convex cone heads 20101; the extrusion plate Ⅰ201 connected to the shear piece Ⅱ3 is provided with a plurality of slots that cooperate with the convex cone heads 20101.

[0026] The working steps of the above embodiment are: first, the harvester carries the present invention to the navel orange tree, and then when the harvester needs to pick the navel oranges at a low place, the harvester first removes the fixing cover 306 to separate the fixing cover 306 from the storage compartment 303, and then grabs the handle 1002 to pull out the plug of the holding rod 1 from the data connection port 305, and then takes out the holding rod 1, the shearing piece I2, the shearing piece II3 and all the parts connected thereto from the storage compartment 303, forming a storage compartment 303 as shown in the figure. Figure 3 The form shown.

[0027] Combination Figure 2 As shown, the harvester then holds the gripping rod 1 with one hand and pushes away the branches or leaves with the other hand, then moves the present invention to the navel orange that needs to be cut, and places the navel orange between the rotating clamping jaw 5 and the fixed clamping jaw 5, then presses the control button Ⅰ1001 with the index finger, and then the motor Ⅰ103 drives the gear 102 to rotate, and the gear 102 engages the rack 101 to drive the shearing piece Ⅱ3 to rotate, so that the shearing piece Ⅱ3 rotates in the direction close to the shearing piece Ⅰ2, and the cutting edges of the two are staggered to cut off the fruit stem of the navel orange; at the same time, during the rotation of the shearing piece Ⅱ3, the shearing piece Ⅱ3 drives the movable support through the connecting rod Ⅰ4001 The ring 4 and the clamping jaws 5 rotate toward the fixed supporting ring 4 and the clamping jaws 5, so that before the shearing pieces II3 and I2 cut the navel oranges, the two clamping jaws 5 can cooperate with each other to clamp the navel oranges first. It should be noted that the clamping jaws 5 are not completely in contact with the navel oranges, so the clamping jaws 5 will not completely fix the navel oranges, but will prevent the navel oranges from falling; thereby preventing the navel oranges from falling after being cut, allowing the harvesters to cut and fix the navel oranges with one hand at the same time, avoiding the need for the harvesters to push away branches and leaves or to hold branches, resulting in the inability to fix the navel oranges, which are easy to fall directly to the ground and need to be picked up again, thereby reducing the collection efficiency.

[0028] Since a plurality of convex cone heads 20101 are arranged on the extrusion plate Ⅰ 201, and the intervals between different convex cone heads 20101 are 1-3 mm, when the fruit stem is between two convex cone heads 20101, it is blocked by the convex cone heads 20101 and is very difficult to escape from between the two convex cone heads 20101, thereby preventing the problem that the fruit stem slips away and cannot be cut when the shearing piece Ⅱ 3 and the shearing piece Ⅰ 2 shear the slightly thicker navel orange fruit stem; when the shearing piece Ⅱ 3 rotates to intersect with the shearing piece Ⅰ 2 but has not completely overlapped, the navel orange can be sheared off; then it is necessary The shearing piece II3 is controlled to continue to rotate until the shearing piece II3 and the shearing piece I2 are completely overlapped like normal scissors, and the convex cone head 20101 is embedded in the corresponding slot, so that the two squeezing plates I201 can be further moved toward each other, so that the fruit stalk is squeezed by the two squeezing plates I201. Through squeezing, the fruit stalk is flattened, deformed and dispersed from a compact cylindrical plant tissue into a flat shape, thereby reducing the hardness of the fruit stalk, which can greatly reduce the probability of the hands of the harvesting workers being pricked or scratched by the hard navel orange stalk when collecting and transporting navel oranges in the navel orange orchard.

[0029] After the harvester cuts the navel oranges, the present invention is moved above the navel orange collection frame, and the harvester presses the control button Ⅰ1001 once again, and then the motor Ⅰ103 drives the gear 102 to reverse. This type of circuit control principle is a mature existing technology and will not be repeated here. The shearing piece Ⅱ3 rotates in a direction away from the shearing piece Ⅰ2, and drives the movable clamping claw 5 to rotate together, so that the clamping claw 5 no longer clamps the navel oranges, and then the navel oranges fall from the clamping claw 5 into the collection frame; then the next shearing work starts, and this reciprocating process is repeated to complete the harvesting of the navel oranges at the lower position.

[0030] When it is necessary to pick the navel oranges that are at a higher place and inconvenient to directly touch, the harvester will put the present invention back into the storage cabin 303 as it is, and ensure that the plug of the gripping rod 1 is inserted into the data connection port 305 to form an electrical connection, as shown in FIG. Figure 1 As shown, the fixing cover 306 is then pressed down onto the storage compartment 303, thereby fixing the holding rod 1, shearing piece I2, shearing piece II3 and all the parts connected thereto in the storage compartment 303. The harvesting worker can then lift the support rod 301 to move the holding rod 1, shearing piece I2, shearing piece II3 and all the parts connected thereto to a higher place. Then, when the navel oranges at a higher place are between the fixed clamping jaw 5 and the rotating clamping jaw 5, since the data connection port 305 is electrically connected to the holding rod 1, the control button II 30101 can replace the control button I 1001 to control the motor I 103 to rotate to pick the navel oranges. Then, the navel oranges fall into the net bag 302 and are temporarily collected. When a large number of navel oranges are collected in the net bag 302, the harvesting worker puts down the support rod 301, pours the navel oranges out of the net bag 302, and collects them into the collection frame, thereby completing the picking of the navel oranges at a higher place.

[0031] It should be noted that some navel oranges at high places have many postures. If the harvesters have to reach each one by adjusting the inclination angle of the support rod 301 relative to the ground, the harvesting work will be very laborious. Therefore, facing navel oranges in various positions and suitable picking angles, the harvesters only need to lift the support rod 301 around the target and press the corresponding control button III 30102 to control the motor II 304 to drive the storage cabin 303 to rotate; for example, pressing the upward control button III 30102 can make the storage cabin 303 deflect upward and increase the elevation angle, and pressing the downward control button III 30102 can make the storage cabin 303 deflect downward and reduce the elevation angle, or even turn it into a depression angle, thereby controlling the rotation of the holding rod 1, the shearing piece I 2, the shearing piece II 3 and all the parts connected thereto, so that the shearing pieces I 2 and II 3 are tilted to a suitable degree of inclination, making it easier for the shearing pieces I 2 and II 3 to cut the fruit stem, reducing the frequency of the harvesters swinging to adjust the angle of the entire support rod 301, and reducing the difficulty of picking navel oranges at high places. Example

[0032] On the basis of Example 1, Figure 4-Figure 5 As shown, it also includes a roller 401, a transmission rope 402, a fixed plate II 403, a rotating rod II 404, an extrusion plate II 405 and a rotating handle 406; the net bag 302 is slidably connected to the support rod 301; the end of the support rod 301 is rotatably connected to the roller 401, and the roller 401 is above the net bag 302; the net bag 302 is fixedly connected to the transmission rope 402; the support rod 301 is fixedly connected to two fixed plates II 403, and the fixed plates II 403 are provided with threaded Hole; a rotating rod Ⅱ 404 is rotatably connected in the threaded holes of all the fixed plates Ⅱ 403, and a thread is arranged on the surface of the rotating rod Ⅱ 404; the transmission rope 402 is tightly sleeved on the roller 401 and the surface of the rotating rod Ⅱ 404 to form a transmission fit; the rotating rod Ⅱ 404 is fixedly connected with an extrusion plate Ⅱ 405, and the extrusion plate Ⅱ 405 cooperates with the fixed plate Ⅱ 403 to frictionally lock the transmission rope 402; the rotating rod Ⅱ 404 is detachably connected with a rotating handle 406.

[0033] Four fixing bars 501 are connected to the bottom of the support rod 301 .

[0034] It also includes a connecting rod II 502, a connecting ring 503, a sleeve 504, a stopper 505 and a spring ball 506; the fixing bar 501 is rotatably connected to the support rod 301; each fixing bar 501 is rotatably connected to a connecting rod II 502; all the connecting rods II 502 are rotatably connected to the connecting ring 503; the support rod 301 is slidably connected to the sleeve 504, and the sleeve 504 is rotatably connected to the connecting ring 503; the surface of the support rod 301 is provided with three annular arrays of class C The sliding groove 30103 is in the shape of a letter "U", and the sliding groove 30103 is composed of two horizontal sliding grooves and one vertical sliding groove, and the two horizontal sliding grooves are respectively connected to the two ends of the vertical sliding groove; three annular array limit blocks 505 are fixedly connected to the inner side surface of the sleeve 504, and the limit blocks 505 slide in the sliding groove 30103; a spring ball 506 is arranged on the surface of each limit block 505; a limit hole 30104 cooperating with the spring ball 506 is arranged on the wall surface of each horizontal sliding groove away from the end of the vertical sliding groove.

[0035] The working steps of the above embodiment are as follows: when a large number of navel oranges are collected in the net bag 302, the harvester needs to put down the support rod 301 to take out the navel oranges in the net bag 302, and the support rod 301 needs to be lifted up again after being put down. Such repeated operation not only consumes a lot of physical strength of the harvester, but also reduces the harvesting efficiency. Therefore, when a large number of navel oranges are collected in the net bag 302, the harvester rotates the rotating handle 406, and the rotating handle 406 drives the squeezing plate II 405 and the rotating rod II 404 to rotate. Since the rotating rod II 404 cooperates with the thread of the fixing plate II 403, the rotating rod II 404 and the squeezing plate II 405 move in the direction away from the transmission rope belt 402, and the squeezing plate II 405 weakens the squeezing and fixing effect on the transmission rope belt 402, and the squeezing plate II 405 does not completely After the net bag 302 is completely separated from the transmission rope 402, it can still cooperate with the fixed plate II 403 in an arc shape to form a slideway that limits the position of the transmission rope 402. The friction of the squeezing plate II 405 on the transmission rope 402 is reduced, and then the net bag 302 begins to slowly slide downward under the influence of gravity. Then, when the net bag 302 moves downward to contact the blocking ring above the control button III 30102, the harvester can take out the navel oranges in the net bag 302 and put them in the collection frame, thereby completing the collection of the navel oranges in the net bag 302. This avoids the problem that after a large number of navel oranges are collected in the net bag 302, the harvester needs to put down the support rod 301 before taking out the navel oranges in the net bag 302, and then lift it up again after putting it down. Such repeated repetition not only consumes a lot of physical strength for the harvester, but also reduces the harvesting efficiency.

[0036] After the navel oranges in the net bag 302 are taken out, the harvester pulls the transmission rope 402 again, thereby pulling the empty net bag 302 upward. When the net bag 302 moves upward to the initial position, the harvester stops pulling the transmission rope 402 and reversely operates the rotating handle 406 to re-tighten the transmission rope 402, thereby restarting the picking of the navel oranges at a high place.

[0037] It should be noted that when retracting the net bag 302, since the net bag 302 contains navel oranges, the upper end of the support rod 301 is heavier. When the harvester holds the support rod 301 with both hands, the impact is not great. However, the harvester needs to free up one hand to rotate the handle 406. At this time, the control force on the support rod 301 will be weakened, and the net bag 302 with a certain weight starts to move again. Therefore, the probability of the support rod 301 being out of control will increase. Therefore, before preparing to retract the net bag 302, the harvester first puts down the support rod 301, stands the support rod 301 on the ground, and then rotates the sleeve 504 to sleeve The sleeve 504 drives the limit block 505 and the spring ball 506 to move horizontally, so that the spring ball 506 is separated from the limit hole 30104 located above. When the limit block 505 rotates to the vertical groove part of the sliding groove 30103, the sleeve 504 stops rotating. Then the harvesting worker pushes the sleeve 504 to move downward. The sleeve 504 drives the connecting ring 503 and the upper end of the connecting rod II 502 to move downward, so that the connecting rod II 502 pushes the fixing bar 501 to rotate away from the support rod 301. Then, when the limit block 505 moves downward to the horizontal groove part below the sliding groove 30103, it is as shown in the figure. Fig. 9 In the state shown, the fixing bar 501 will contact the ground, thereby increasing the contact area with the ground, making it more difficult for the support rod 301 to fall down, and making it easier for the harvester to control the support rod 301. The harvester then rotates the sleeve 504 in the opposite direction, so that the limit block 505 enters the horizontal groove part below the sliding groove 30103. Then, when the spring ball 506 is aligned with the limit hole 30104 located below, the spring inside the spring ball 506 pushes the spring ball 506 into the limit hole 30104 located below, thereby limiting the limit block 505 and the sleeve 504, so that the sleeve 504 will not rotate easily. Then, even if the harvester frees up one hand to control the rotating handle 406, it is difficult for the support rod 301 to fall out of control.

[0038] It should be noted that, because the distance that the harvester needs to move with the support rod 301 is relatively short under a navel orange tree, when picking navel oranges at a high place on the same navel orange tree, the harvester only needs to move a short distance even if he needs to move, and can keep the fixed bar 501 in the unfolded state while moving with the support rod 301. When picking is finished and another navel orange tree needs to be picked, a longer distance needs to be moved, and the unfolded state of the fixed bar 501 is not convenient for transferring the support rod 301 and will hinder the movement of the harvester. At this time, the harvester needs to retract the fixed bar 501 and reset it so that the fixed bar 501 rotates to the position as shown in the figure. Figure 8 The state shown makes it easier for harvesting workers to move with the support rod 301 .

[0039] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
