Description

Technical Field

[0001] The invention relates to the field of navel orange picking, in particular to a navel orange picking device. Background Art

[0002] At present, when picking navel oranges, since navel orange trees usually grow in hilly areas, navel orange picking devices used in flat areas cannot be used. As a result, when picking navel oranges in high places, it is necessary to manually climb ladders to pick the navel oranges, which is very dangerous. There is also a method of using long-handled scissors to pick navel oranges, but because different navel oranges hang in different directions and navel oranges are usually clustered together, other navel oranges and branches will block the movement of the scissors during the picking process, making it difficult to use the long-handled scissors to approach the branches of the navel oranges and cut them, resulting in inconvenience in picking. At the same time, there are a lot of leaves around the navel oranges, which will also block the branches of the navel oranges. As a result, when manually using long-handled scissors to pick navel oranges, the leaves need to be pushed aside before the navel oranges can be picked, resulting in low picking efficiency.

[0003] Moreover, after the navel oranges are picked, the branches of the navel oranges are often too long and need to be manually pruned, which is a cumbersome operation. Summary of the Invention

[0004] In order to overcome the shortcomings of existing devices that it is difficult to get close to the branches of navel oranges and cut them, and a second pruning is required after the navel oranges are picked, which is cumbersome to operate, the present invention provides a navel orange picker.

[0005] The technical solution is as follows: A navel orange picker includes a telescopic rod and a support ring; a handle is provided on the telescopic rod; a control system is built into the handle, and a plurality of control buttons are provided on the handle; the support ring is fixedly connected to the telescopic rod, and a power supply is provided inside the support ring; it also includes a mounting ring and a cutting assembly; the mounting ring is fixedly connected to the support ring; and the mounting ring is connected to a cutting assembly for cutting branches.

[0006] Preferably, the cutting assembly includes a fixed ring, an electric rotating shaft and a cutter; the fixed ring is fixedly connected to the upper side of the mounting ring; two electric rotating shafts distributed upper and lower are connected to the fixed ring; and a semi-circular cutter for cutting branches is fixedly connected to the rotating part of the two electric rotating shafts.

[0007] Preferably, it further comprises a bellows and a guide cylinder; the bellows is provided in the support ring for guiding the navel oranges to fall; the guide cylinder is fixedly connected to and communicated with the bellows.

[0008] Preferably, it also includes a micro pump, a micro electric push rod, a limiting ring and a first directional airbag; the micro pump is fixedly connected to the support ring; a number of micro electric push rods are fixedly connected to the support ring; the telescopic end of the micro electric push rod is fixedly connected to the limiting ring; the first directional airbag for clamping branches is fixedly connected to the inner side of the limiting ring; the inner side of the first directional airbag is the contraction end; the first directional airbag is connected to the micro pump through a telescopic air tube.

[0009] Preferably, a second directional airbag is further included; the second directional airbag for clamping and limiting branches is fixedly connected to the inner side of the mounting ring; the inner side of the first directional airbag is a contraction end; the second directional airbag is connected to the micro pump through an air tube.

[0010] Preferably, the upper layer of the second directional airbag is made of a hard material.

[0011] Preferably, a screen is provided on the lower side of the guide cylinder.

[0012] Preferably, a guiding slope is provided on the upper side of the limiting ring.

[0013] Preferably, it further comprises a shoulder strap, a cushion and a support block; the shoulder strap is provided on the lower side of the telescopic rod; the cushion is fixedly connected to the right side of the shoulder strap; the support block is fixedly connected to the cushion; and a through slot is provided on the support block.

[0014] Preferably, rubber particles are provided on the inner wall of the through groove.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes that the telescopic rod is manually driven to move upward and vibrate simultaneously, thereby driving the limiting ring to vibrate, so that the limiting ring is gradually inserted upward into the gap between the navel orange to be picked and the adjacent navel oranges through the guiding inclined surface on the limiting ring, and the guiding inclined surface is continuously vibrated to guide and push the adjacent navel oranges outward, so that they move in a direction away from the navel oranges to be picked, thereby preventing the adjacent navel oranges from blocking the upward movement of the support ring, resulting in the navel oranges failing to move relative to the mounting ring to below the mounting ring, thereby effectively preventing interference with the picking operation when there are many navel oranges;

[0016] By putting the navel oranges into the support ring, the installation ring and the fixing ring, and then cutting the branches, it is different from using long-handled scissors to pick the navel oranges, so that when picking the navel oranges, there is no need to push away the leaves before picking the navel oranges;

[0017] The first directional airbag drives the clamped branch to move upward, so that the navel orange connected to the branch moves upward until it is tightly fitted with the lower side of the second directional airbag. When the upper side of the navel orange contacts the lower side of the second directional airbag, the first directional airbag continues to drive the navel orange upward to squeeze the second directional airbag, causing the second directional airbag to deform adaptively, so that the upper end of the navel orange is as close to the cutter as possible. At the same time, the hard upper layer of the second directional airbag keeps the upper layer of the second directional airbag flat, thereby preventing the cutter from contacting the second directional airbag and causing the second directional airbag to be cut. At the same time, the upper end of the navel orange is brought closer to the cutter, and the branches at the ends of the navel orange are closer to the cutter. After the branches are cut, the remaining branches on the navel orange are shorter, so that there is no need to manually cut the branches, reducing labor intensity and effectively improving the efficiency of picking navel oranges.

[0018] When picking navel oranges, the staff can wear a brace with the cushion and the support block located in front of the chest, then insert the lower end of the telescopic rod into the through-groove of the support block, and then tilt the telescopic rod to rest against the through-groove. The telescopic rod is supported by the inner wall of the through-groove to reduce the support pressure on the hand, effectively relieving the staff's fatigue. At the same time, the cushion is used for buffering to avoid a large squeezing force on the staff's chest when the telescopic rod is supported by the support block, causing discomfort to the staff. Moreover, by placing the telescopic rod on the through-groove of the support block, the staff can free their hands when they receive or need to make a call during the picking process.

DETAILED DESCRIPTION

[0024] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Example 1

[0025] like Figures 1-4 As shown, a navel orange picker includes a telescopic rod 1 and a support ring 2; the telescopic rod 1 is provided with a handle 1001; the handle 1001 has a built-in control system and a plurality of control buttons; the telescopic rod 1 is fixedly connected to the support ring 2, and the support ring 2 is provided with a power supply;

[0026] It also includes a mounting ring 3 and a cutting assembly; the mounting ring 3 is fixedly connected to the upper side of the support ring 2; and the cutting assembly is connected to the mounting ring 3.

[0027] The cutting assembly includes a fixed ring 4, an electric rotating shaft 101 and a cutter 102; the fixed ring 4 is fixedly connected to the upper side of the mounting ring 3; the fixed ring 4 is connected to two electric rotating shafts 101 distributed up and down; a semi-annular cutter 102 is fixedly connected to the rotating part of the two electric rotating shafts 101.

[0028] It also includes a bellows 5 and a guide tube 6; the bellows 5 is arranged inside the support ring 2; the lower side of the bellows 5 is fixedly connected to and communicated with the guide tube 6.

[0029] It also includes a micro pump 201, a micro electric push rod 301, a limiting ring 302 and a first directional airbag 303; the micro pump 201 is fixedly connected to the inside of the support ring 2; two micro electric push rods 301 are fixedly connected to the support ring 2; the telescopic end of the micro electric push rod 301 is fixedly connected to the limiting ring 302; the first directional airbag 303 is fixedly connected to the inner side of the limiting ring 302; the inner side of the first directional airbag 303 is the contraction end; the first directional airbag 303 is connected to the micro pump 201 through a telescopic air tube.

[0030] It also includes a second directional airbag 401; the second directional airbag 401 is fixedly connected to the inner side of the mounting ring 3; the inner side of the first directional airbag 303 is a contraction end; the second directional airbag 401 is connected to the micro pump 201 through an air tube.

[0031] The upper layer of the second directional airbag 401 is made of hard material.

[0032] A screen 6001 is provided on the lower side of the guide cylinder 6 .

[0033] A guiding slope 30201 is provided on the upper side of the limiting ring 302 .

[0034] During operation, the micro electric push rod 301 and the micro pump 201 are connected to the power supply on the support ring 2, a storage box is placed at the lower opening of the guide cylinder 6, and the lower opening of the guide cylinder 6 and the storage box are engaged and fixed with each other, then the telescopic rod 1 is stretched to a certain length, the corrugated tube 5 is adaptively stretched and expanded, and then the staff holds the lower side of the telescopic rod 1 and adjusts the angle of the telescopic rod 1 to move the support ring 2 to the right below the navel oranges 7 to be picked, and makes the support ring 2 parallel to the navel oranges 7 to be picked, so as to facilitate the picking of the navel oranges 7, and then pushes the telescopic rod 1 upwards, and drives the support ring 2 to move to the lower side of the navel oranges 7 to be picked. The supporting ring 2, the mounting ring 3 and the fixing ring 4 move upwards, so that the navel orange 7 to be picked just above the supporting ring 2 enters the interior of the supporting ring 2, the mounting ring 3 and the fixing ring 4. It should be noted that at this time, the limiting ring 302 is in contact with the fixing ring 4. When the staff observes that the navel orange 7 to be picked has completely entered the supporting ring 2, the mounting ring 3 and the fixing ring 4, that is, after the navel orange 7 to be picked is blocked by the supporting ring 2, the mounting ring 3 and the fixing ring 4, the staff stops pushing the telescopic rod 1 upwards. At this time, the navel orange 7 is located below the mounting ring 3, and the branch 71 connected to the navel orange 7 is located in the middle of the fixing ring 4 and the limiting ring 302. Then, as shown in FIG. Figure 4 As shown, the micro pump 201 is controlled to blow air into the second directional airbag 401, causing the second directional airbag 401 to expand and extend, thereby clamping the branch 71 of the navel orange 7 through the second directional airbag 401. At the same time, the micro pump 201 also blows air into the first directional airbag 303, causing the first directional airbag 303 to expand and extend, thereby clamping the upper part of the branch 71 through the first directional airbag 303. Then, the micro electric push rod 301 is controlled to push the limiting ring 302 upward. The limiting ring 302 drives the first directional airbag 303 to move upward, and then drives the branch 71 clamped by the first directional airbag 303 to move upward, so that the navel orange 7 connected to the branch 71 is clamped. The orange 7 moves upward until it is in close contact with the lower side of the second directional airbag 401. Then, the two electric shafts 101 are controlled to drive the corresponding cutters 102 to rotate toward each other, so that the two cutters 102 cooperate with each other to cut the branch 71, separating the navel orange 7 from the connected branch 71. During this process, the first directional airbag 303 pulls the branch 71 upward, and the second directional airbag 401 limits the position of the branch 71. The first directional airbag 303 and the second directional airbag 401 cooperate to keep the branch 71 taut and fixed, thereby effectively preventing the branch 71 from shifting when the cutter 102 cuts the branch 71, resulting in shearing failure.

[0035] When there are many navel oranges 7 above the support ring 2 and the distance between the navel oranges 7 is small, in the process of pushing the telescopic rod 1 upward and inserting the navel orange 7 directly above the support ring 2 into the support ring 2, the mounting ring 3 and the fixing ring 4, the telescopic rod 1 is manually driven to shake, thereby driving the limit ring 302 to shake, so that the limit ring 302 is gradually inserted upward into the gap between the navel orange 7 to be picked and the adjacent navel oranges 7 through the guiding inclined surface 30201 on the limit ring 302, and the guiding inclined surface 30201 is continuously shaken to guide and push the adjacent navel oranges 7 outward, so that they move in the direction away from the navel oranges 7 to be picked, thereby preventing the adjacent navel oranges 7 from blocking the upward movement of the support ring 2, thereby effectively preventing interference with the picking operation when there are too many navel oranges 7;

[0036] Here, the navel orange 7 is yellow and the leaves are green. The navel orange 7 is more conspicuous than the leaves, so the navel orange 7 can be quickly found manually and quickly inserted into the support ring 2, the installation ring 3 and the fixing ring 4.

[0037] At the same time, by inserting the navel orange 7 into the supporting ring 2, the mounting ring 3 and the fixing ring 4, and then cutting the branch 71, it is different from using long-handled scissors to pick the navel orange 7. When picking the navel orange 7, there is no need to push away the leaves before picking the navel orange 7. Since the branches 71 remaining on the navel orange 7 are too long after the navel orange 7 is picked, it is necessary to manually shorten the branches 71 remaining on the navel orange 7, which is cumbersome. In this device, it should be noted that when the micro-electric push rod 301 drives the first directional airbag 303 to move upward, the first directional airbag 303 drives the clamped branch 71 to move upward, so that the navel orange 7 connected to the branch 71 moves upward until it is tightly fitted with the lower side of the second directional airbag 401. The second directional airbag 401 continues to drive the navel orange 7 upward through the first directional airbag 303 to squeeze the second directional airbag 401, causing the second directional airbag 401 to deform adaptively, thereby bringing the upper end of the navel orange 7 as close to the cutter 102 as possible. At the same time, since the upper layer of the second directional airbag 401 is made of a hard material, the upper layer of the second directional airbag 401 always remains flat, thereby preventing the cutter 102 from colliding with the second directional airbag 401, resulting in the second directional airbag 401 being cut. At the same time, the upper end of the navel orange 7 is brought closer to the cutter 102, and the branches 71 at the ends of the navel orange 7 are closer to the cutter 102. After the branches 71 are cut, there is no need to manually cut the branches 71, thereby reducing labor intensity and effectively improving the efficiency of picking the navel oranges 7.

[0038] Then, the micro pump 201 is controlled to evacuate the first directional airbag 303 and the second directional airbag 401, so that the first directional airbag 303 and the second directional airbag 401 are contracted. At the same time, the micro electric push rod 301 drives the limit ring 302 to reset, so as to facilitate the next picking operation. The navel orange 7 with the cut branch 71 loses support and falls downward, and then slides downward from the corrugated tube 5. When the navel orange 7 slides into the guide cylinder 6, the navel orange 7 is buffered by the screen 6001, thereby effectively preventing the navel orange 7 from being damaged. Then, the navel orange 7 finally falls into the storage box connected to the guide cylinder 6 for collection. Through the cooperation of the corrugated tube 5 and the guide cylinder 6, the navel orange 7 can be quickly guided into the storage box after being picked, avoiding the navel orange 7 falling to the ground after being cut and needing to be collected manually, thereby effectively improving the picking efficiency of the navel orange 7. Moreover, since the corrugated tube 5 can be retracted, the device can pick navel oranges 7 at different heights.

[0039] When the navel orange 7 is clamped by the second directional airbag 401, it is inevitable that a small number of branches 71 that are not connected to the navel orange 7 will be clamped, so that a small amount of broken branches 71 and broken leaves enter the transmission channel together with the navel orange 7. When the broken branches 71, broken leaves and navel orange 7 slide into the guide cylinder 6, the broken branches 71 and broken leaves pass through the sieve holes of the screen 6001 and fall to the ground, thereby achieving the screening of the broken branches 71 and broken leaves entering the transmission channel by the screen 6001, effectively reducing the later processing work of the navel orange 7. Example 2

[0040] On the basis of Example 1, Figure 1 As shown, it also includes a shoulder strap 501, a cushion 502 and a support block 503; the shoulder strap 501 is provided on the lower side of the telescopic rod 1; the cushion 502 is fixedly connected to the right side of the shoulder strap 501; the support block 503 is fixedly connected to the cushion 502; and a through slot 50301 is opened on the support block 503.

[0041] Rubber particles are provided on the inner wall of the through groove 50301 .

[0042] When picking navel oranges 7, the staff can wear the shoulder strap 501, place the soft pad 502 and the support block 503 in front of the chest, and then insert the lower end of the telescopic rod 1 into the through-groove 50301 of the support block 503. Then, the telescopic rod 1 is tilted and pressed against the through-groove 50301, so that the telescopic rod 1 is supported by the inner wall of the through-groove 50301, thereby reducing the supporting pressure of the hand and effectively relieving the staff's fatigue. In addition, the rubber particles provided on the inner wall of the through-groove 50301 increase the friction between the telescopic rod 1 and the inner wall of the through-groove 50301, effectively preventing the telescopic rod 1 from sliding in the through-groove 50301 when the telescopic rod 1 is supported by the support block 503. At the same time, the soft pad 502 provides a buffer, avoiding a large squeezing force on the chest of the staff when the telescopic rod 1 is supported by the support block 503, causing discomfort to the staff.

[0043] Furthermore, by placing the telescopic rod 1 on the through slot 50301 of the support block 503, the workers can free their hands when they receive or need to make a phone call during the picking process.
