Description

Technical Field

[0001] The invention relates to the technical field of fruit picking, in particular to a citrus fruit picking device. Background Art

[0002] Citrus is a plant of the Rutaceae family and the genus Citrus. It is widely grown around the world and is a fruit with high economic value and is deeply loved by the public. In the process of citrus cultivation, citrus picking devices are often needed to pick citrus. Direct manual picking is the most traditional and common method.

[0003] Traditional picking methods rely on climbing fruit trees or using high ladders to perform high-altitude operations, which exposes workers to safety risks such as falling from heights. In contrast, picking poles effectively avoid such risks. However, existing picking poles may not be able to accurately align the cutting part with the fruit branches, and the branches are sharp when cut, and when they fall, they hit other fruits, easily causing damage, affecting the quality of picking, and causing damage to the integrity of the fruit and surrounding plants. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a citrus fruit picking device, which solves the problem that picking rods are easily damaged by collision at the places where fruit branches are cut.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a citrus fruit picking device, comprising a picking rod, wherein the picking rod is rotatably connected to a rotating frame 1 on the upper side of the outer wall, and the lower side of the outer wall of the picking rod is rotatably connected to a rotating frame 2, and the rotating frame 1 and one side of the outer wall of the rotating frame 2 are jointly fixedly connected with an observation component, the top of the rotating frame 1 is rotatably connected to a fixed sleeve, the lower side of the inner wall of the fixed sleeve is fixedly connected to the outer wall of the picking rod, the top of the fixed sleeve is rotatably connected to a support disk, the top of the rotating frame 1 is connected to a plurality of connecting blocks through a contraction component, the top of the connecting block is fixedly connected to a shearing knife, the top of the support disk is provided with a plurality of straight sliding grooves, the outer wall of the connecting block is slidably connected to the inner wall of the straight sliding groove, and the top of the inner end of the shearing knife is arranged with an arc-shaped blade for cutting fruit branches.

[0006] Preferably, the observation assembly includes a periscope fixedly connected to one side of the outer wall of rotating frame one and rotating frame two, periscope two is fixedly connected to the lower side of the inner wall of the periscope, one end of the periscope faces the shear knife, and the other end of the periscope faces downward, periscope one is fixedly connected to the upper side of the inner wall of the periscope, and periscope one and periscope two are arranged to be parallel to each other and have an angle of forty-five degrees with the horizontal plane.

[0007] Preferably, a funnel is fixedly connected to the top of the picking rod, and a sponge pad is fixedly connected to the inner wall of the picking rod.

[0008] Preferably, the lower side of the outer wall of the picking rod is curved in an arc shape, the end of the curved portion of the picking rod is fixedly connected with a flared opening, and the four sides of the outer wall of the flared opening are fixedly connected with hooks.

[0009] Preferably, the shrinkage assembly includes a shrinkage disk rotatably connected to the inner wall of the support disk, an inner end of the shrinkage disk is fixedly connected to an adjusting rod, the bottom end of the adjusting rod is fixedly connected to the top edge of the rotating frame, a plurality of arc-shaped grooves are provided on the inner wall of the shrinkage disk, the number of the arc-shaped grooves corresponds to the number of shear knives, an arc-shaped slider is slidably connected to the inner wall of the arc-shaped groove, a rotating shaft is rotatably connected to the top end of the arc-shaped slider, and the top end of the rotating shaft is fixedly connected to the bottom end of the connecting block.

[0010] Preferably, one end of the outer wall of the shrink disk is fixedly connected to a second torsion spring, and the other end of the second torsion spring is fixedly connected to the inner wall of the support disk.

[0011] Preferably, an adjusting groove is provided at the bottom end of the supporting plate, the adjusting rod is sleeved on the inner wall of the adjusting groove, and the inner wall of the adjusting groove is in a semicircular arc shape.

[0012] Preferably, a torsion spring 1 is fixedly connected to the bottom end of the inner wall of the fixed sleeve, the top end of the torsion spring 1 is fixedly connected to the bottom end of the support plate, and a set of the torsion spring is arranged on the outer wall of the picking rod.

[0013] Working principle: First, the staff holds the picking rod to the tree where the citrus fruits need to be picked, and then aligns the picking rod with the approximate position of the fruits to be picked, observes the fruits aimed at by the shearing knife in the internal periscope 1 through the lower end of the periscope, and then accurately adjusts the position of the shearing knife to align with the branches of the fruits, and then manually rotates the rotating frame 2 to drive the rotating frame 1 to rotate through the tube body of the periscope, and then drives the shrinking disk to rotate on the inner wall of the support disk through the adjusting rod, so that the arc-shaped slider on the inner wall of the arc-shaped slide groove is squeezed toward the center by the edge of its inner wall. The connecting block slides to the innermost side of the straight slide groove, and the arc-shaped shearing knife moves closer to the root of the middle branch. Continuing to rotate the adjusting rod will drive the supporting plate to rotate on the top of the fixed sleeve, so that the cutting surface of the branch forms an arc shape, and the fruit is picked and dropped into the funnel, and then slides down along the inner wall of the picking rod, and the picking operation is completed in the storage bag suspended on the expansion under the picking rod.

[0014] The present invention provides a citrus fruit picking device having the following beneficial effects:

[0015] 1. Through the cooperation of the periscope, periscope one and periscope two, the staff can clearly observe the fruit and the corresponding branch position that the shearing knife is aimed at, so that the shearing knife can be accurately adjusted to the fruit branch, the occurrence of miscutting can be reduced, and the target fruit can be picked accurately, which helps to ensure that the fruit is intact without damaging the surrounding unripe or unneeded fruits and branches.

[0016] 2. The present invention allows workers to stand under the tree and hold a picking rod to operate. There is no need to climb the fruit tree or use a high ladder or other high-altitude operations like traditional picking, which avoids the safety risks brought by climbing and reduces the physical exertion of workers, making the picking work relatively easy.

[0017] 3. When the shear knife of the present invention cuts the branches, the support plate can be driven to rotate by continuously rotating the adjusting rod, so that the cut surface of the branches can be formed into an arc shape. This cutting method is relatively smooth and regular, and can avoid damage to the fruit due to collision, tearing, etc. when it falls from the branch due to harsh cutting. It helps to ensure the quality of citrus fruits after picking and is beneficial to subsequent storage and sales.

[0018] 4. The cut fruits of the present invention can directly fall into the funnel arranged inside the picking rod, and slide along the inner wall of the picking rod to the storage bag hanging below, forming a relatively smooth collection process, reducing the cumbersome process of secondary picking of fruits scattered on the ground, and improving the picking efficiency and the integrity of fruit collection.

[0028] Example:

[0029] like Figure 1-7 As shown, an embodiment of the present invention provides a citrus fruit picking device, including a picking rod 1, a picking rod 1, a rotating frame 2 is rotatably connected to the upper side of the outer wall, a rotating frame 2 is rotatably connected to the lower side of the outer wall of the picking rod 1, a periscope 9 is fixedly connected to one side of the outer wall of the rotating frame 2 and the rotating frame 2 12, a periscope 2 14 is fixedly connected to the lower side of the inner wall of the periscope 9, one end of the periscope 9 faces the shear knife 5, and the other end of the periscope 9 faces downward, a periscope 13 is fixedly connected to the upper side of the inner wall of the periscope 9, and the periscope 13 and the periscope 2 14 are arranged to be parallel to each other and have an angle of forty-five degrees with the horizontal plane:

[0030] Specifically, the rotating frame 1 2 and the rotating frame 2 12 are both rotatably connected to the outer wall of the picking rod 1 through internal slide rails. The actual length of the picking rod 1 is designed according to production needs. The mirror surfaces of the periscope 1 13 and the periscope 2 14 are plane reflectors, so that the operator can monitor the position dynamics of the shear knife 5 in real time with the help of the periscope system to ensure that it is accurately aligned with the branches of the citrus fruit.

[0031] The top of the rotating frame 2 is rotatably connected with a fixed sleeve 3, the lower side of the inner wall of the fixed sleeve 3 is fixedly connected to the outer wall of the picking rod 1, the top of the fixed sleeve 3 is rotatably connected with a support plate 7, the top of the connecting block 17 is fixedly connected with a shearing knife 5, the top of the supporting plate 7 is provided with a plurality of straight slide grooves 4, the outer wall of the connecting block 17 is slidably connected to the inner wall of the straight slide groove 4, the top of one end of the inner side of the shearing knife 5 is arranged with an arc-shaped blade for cutting fruit branches, the inner wall of the supporting plate 7 is rotatably connected with a contraction plate 16, one end of the inner side of the contraction plate 16 is fixedly connected with an adjusting rod 8, the bottom end of the adjusting rod 8 is fixedly connected to the top edge of the rotating frame 2, and the inner wall of the contraction plate 16 is provided with a plurality of arc-shaped slide grooves 18. The number of arc-shaped slide grooves 18 corresponds to the number of shear knives 5. The inner wall of the arc-shaped slide groove 18 is slidably connected with an arc-shaped slider 15. The top of the arc-shaped slider 15 is rotatably connected with a rotating shaft 19. The top of the rotating shaft 19 is fixedly connected with a connecting block 17. One end of the outer wall of the shrink disk 16 is fixedly connected with a torsion spring 23. The other end of the torsion spring 23 is fixedly connected to the inner wall of the support disk 7. An adjusting groove 21 is provided at the bottom end of the support disk 7. The adjusting rod 8 is sleeved on the inner wall of the adjusting groove 21. The inner wall of the adjusting groove 21 is semicircular. The bottom end of the inner wall of the fixed sleeve 3 is fixedly connected with a torsion spring 20. The top of the torsion spring 20 is fixedly connected to the bottom end of the support disk 7. The torsion spring 20 is sleeved on the outer wall of the picking rod 1.

[0032] Specifically, the torsion spring 1 20 facilitates the reset rotation of the support disk 7 after rotation, and the torsion spring 23 facilitates the reset of the shrink disk 16 on the inner wall of the support disk 7, thereby facilitating the opening control of the shear knife 5. The rotating frame 2 12 is manually rotated. Since the rotating frame 2 12 is connected to the tube body of the periscope tube 9, the rotation of the rotating frame 2 12 will drive the tube body of the periscope tube 9 to rotate, thereby driving the rotating frame 1 2 to rotate.

The bottom end of the adjustment rod 8 is fixed to the top edge of the rotating frame 1 2, and the adjustment rod 8 is sleeved on the inner wall of the adjustment groove 21 opened at the bottom end of the support disk 7. The inner wall of the adjustment groove 21 is semicircular, which enables the adjustment rod 21 to move stably along the adjustment groove 21 when rotating. The movement of the adjustment rod 8 drives the shrink disk 16 to rotate 8 on the inner wall of the support disk 7. During the rotation of the shrink disk 7, the inner wall of the arc-shaped slide groove 18 will produce a squeezing effect on the arc-shaped slider 15. Under this extrusion, the arc-shaped slider 15 will slide toward the middle. As the arc-shaped slider 15 slides, the inner wall of the straight slide groove 4 opened at the top of the support plate 7 of the connecting block 17 is driven to slide toward the middle through the top rotating shaft 19, thereby realizing the movement of the shear knife 5 toward the middle branch root.

[0033] A funnel 6 is fixedly connected to the top of the picking rod 1, a sponge pad 22 is fixedly connected to the inner wall of the picking rod 1, the lower side of the outer wall of the picking rod 1 is curved, a flare 11 is fixedly connected to the end of the curved portion of the picking rod 1, and hooks 10 are fixedly connected to the four sides of the outer wall of the flare 11;

[0034] Specifically, the sponge pad 22 ensures that the fruit is not easily damaged when falling from the inner wall of the picking rod 1. The hook on the expanded outer wall facilitates hanging net bags and other structures to catch the citrus fruits. The curved outer wall of the picking rod 1 facilitates the buffering of the fruit from falling out of the expanded opening 11.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
