Description

Technical Field

[0001] The utility model belongs to the technical field of walnut tree planting, in particular to a walnut tree shaping and pruning device. Background Art

[0002] Walnut trees, also known as walnuts, belong to the Juglandaceae family. Varieties include wild walnuts and artificially grafted varieties. Native to Central Asia, they are cultivated throughout China. Artificially grafted varieties are generally preferred because they yield higher yields than wild varieties and have thinner shells, often called soaked walnuts. Wild varieties have thicker shells, are larger, and contain more oil, resulting in a more fragrant taste and are often called iron walnuts. Pruning walnut trees is a process of shaping the tree into a specific shape to improve its structure, fruit quality, and yield. Pruning is a key technical measure in walnut cultivation and management, enabling young trees to bear fruit earlier, entering their productive period earlier, and extending their lifespan.

[0003] At present, the shaping and pruning of walnut trees is mostly done by workers with scissors. Although the pruning work can be achieved, it can only prune branches within a limited height. If climbing trees or using ladders to prune high branches, it not only increases the difficulty of the operation, but also significantly increases the risk of safety accidents, posing a potential threat to the lives of workers.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present invention provides a walnut tree shaping and pruning device. Figure 1-3 As shown, the shaping and pruning device for walnut trees includes: a box body 1, on which two straps 2 are fixedly installed; a rotating shaft 3 rotatably installed on one side of the box body 1, and a cylinder 4 is welded to the rotating shaft 3; an electric push rod 5 fixedly installed on the inner wall of the cylinder 4, and a shell 6 is fixedly installed on the output rod of the electric push rod 5; a first motor 7 fixedly installed on the inner wall of the shell 6, and a support block 8 is fixedly installed on the output shaft of the first motor 7, and a cavity and a sliding groove are provided on the support block 8; a pruning mechanism for shaping walnut trees is assembled on the support block 8.

[0021] In this embodiment, when in use, workers can use two straps 2 to carry the entire device on their backs, which can reduce the burden of holding the device and enable workers to move the device with less effort. After moving to the walnut tree that needs to be shaped and pruned, the cylinder 4 is first rotated by hand. At this time, the rotating shaft 3 connected to the cylinder 4 will also rotate on the box body 1. The rotation of the cylinder 4 can adjust the use height of the pruning mechanism. If the pruning height is not enough, the electric push rod 5 is started to drive the shell 6 to move. The shell 6 will drive the first motor 7, the support block 8 and the pruning mechanism to move in a straight line, so that the pruning mechanism can be moved to a suitable height for use, and then the pruning mechanism can be used to prune the branches of the walnut tree without climbing. It is safer to use and effectively reduces the difficulty of the operation. If the pruning angle needs to be adjusted, the first motor 7 needs to be started. The first motor 7 will drive the support block 8 and the pruning mechanism to rotate, and then the pruning mechanism can be adjusted to the required angle for use, and the adjustment is more convenient.

[0022] In a further preferred embodiment of the present utility model, the trimming mechanism includes: a screw 9 rotatably mounted on the inner walls on both sides of the sliding groove, one end of the screw 9 extending into the interior of the cavity; a second motor 10 fixedly mounted on the inner wall of the cavity, the output shaft of the second motor 10 fixedly connected to one end of the screw 9; a slider 11 threadedly mounted on the screw 9, the slider 11 being slidably connected to the inner wall of the sliding groove; a first blade 12 fixedly mounted on the support block 8; and a second blade 13 fixedly mounted on the slider 11.

[0023] In this embodiment, the pruning mechanism is used for shaping walnut trees. When shaping and pruning walnut trees, if the pruning mechanism is to be used, the second motor 10 needs to be started. The second motor 10 will drive the screw 9 to rotate, and the screw 9 will drive the slider 11 to move in the sliding groove. The slider 11 will drive the second blade 13 to move, so that the second blade 13 is close to the first blade 12. When the second blade 13 contacts the first blade 12, the pruning of the walnut branches can be completed once, and the pruning is more convenient and labor-saving.

[0024] In a further preferred embodiment of the present invention, two installation grooves are provided on the cylinder 4 , and limiting rods 14 are slidably installed on the inner walls of the two installation grooves, and one end of the two limiting rods 14 is fixedly connected to the shell 6 .

[0027] In this embodiment, multiple connecting blocks 15 can improve the stability of the support block 8 during use, reduce the supporting force of the first motor 7 on the support block 8, and avoid damage to the output shaft of the first motor 7 due to excessive force, thereby providing better protection for the first motor 7.

[0028] In a further preferred embodiment of the present invention, a cushion 16 is fixedly installed on one side of the box body 1 , and a battery 19 is provided inside the box body 1 .

[0029] In this embodiment, the cushion 16 can improve the comfort of the worker's back in contact with the box 1, and the battery 19 can be used to power the device.

[0030] In a further preferred embodiment of the present invention, a handrail 17 is fixedly mounted on one side of the cylinder 4 , and a controller 18 is fixedly mounted on the handrail 17 .

[0031] In this embodiment, the handrail 17 can facilitate workers to manually rotate the cylinder 4, and the controller 18 can facilitate workers to control the operation of the device.

[0032] In a further preferred embodiment of the present invention, a sliding rod 20 is fixedly mounted on the inner wall of the sliding groove, and the sliding rod 20 is slidably connected to the sliding block 11 .

[0033] In this embodiment, the use of the slide rod 20 can improve the stability of the slider 11 during movement and make it less likely to deviate. When the second motor 10 drives the screw 9 to rotate, the slider 11 threadedly connected to the screw 9 will stably slide horizontally on the slide rod 20, and the sliding process is relatively stable.

[0034] To sum up, compared with the relevant technology, this solution can carry the entire device on the body for use through the use of two straps 2, which can reduce the burden of holding the device and enable workers to move the device more effortlessly. Through the use of the handrail 17, it is convenient for workers to rotate the cylinder 4 by hand. The rotation of the cylinder 4 can adjust the use height of the pruning mechanism. If the pruning height is not enough, the electric push rod 5 can be used to continue to adjust the use height of the pruning mechanism. In this way, the pruning mechanism can be used to prune the branches of the walnut tree without climbing. It is safer to use and effectively reduces the difficulty of the operation. Through the use of the first motor 7, the angle of the pruning mechanism can be adjusted according to the pruning situation, and the adjustment is more convenient.

[0035] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
