Description

Technical Field

[0001] This utility model relates to the technical field of tree peeling, specifically to a portable tree peeling machine. Background Technology

[0002] Removing the old bark from jujube trees is a crucial orchard management practice, especially for mature trees. This work is typically carried out in winter or early spring. Pests such as spider mites, leaf miners, gall midges, and inchworms often choose to lay eggs or pupate under the rough, old bark of jujube trees. Scraping off the old bark directly exposes these hidden pests and their eggs, causing them to freeze to death in the low temperatures or be preyed upon by natural enemies, effectively reducing the pest population in the following spring. The young phloem of jujube trees also has a certain photosynthetic capacity. Removing the old, impermeable layer of dead bark facilitates gas exchange and weak photosynthesis in the bark, enhancing the tree's growth and slightly stimulating the activity of cambium cells, promoting the formation of new bark. Furthermore, the mycelium and spores of pathogens causing diseases such as jujube rust, anthracnose, and ring rot can also lurk in the crevices of the old bark. Removing the old bark is equivalent to a thorough orchard sanitation, reducing the initial sources of disease infection.

[0003] Because the surface of jujube trees is irregularly shaped, in order to avoid damaging the young phloem during the peeling process, the peeling of jujube trees is done manually. The main tool used is a peeling chain, which requires manual holding of both ends to move the chain across the surface of the jujube tree. This is physically demanding and the peeling work is arduous. As time goes on, the peeling efficiency gradually decreases. Therefore, it is necessary to design a portable tree peeling machine. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problems of high labor intensity and low efficiency in the use of peeling chains in the prior art.

[0005] To achieve the above objectives, this utility model provides a portable tree peeling machine, comprising: a trolley, a power supply battery mounted on the trolley, a mounting frame, a handle fixedly connected to the mounting frame, a stepper motor fixedly mounted on the mounting frame, a rotating arm fixedly connected to the output shaft of the stepper motor in the center, and a peeling chain. One end of the peeling chain is hinged to one end of the rotating arm via a first hinge, and the other end of the peeling chain is equipped with a second hinge. The second hinge is detachably connected to the end of the rotating arm away from the first hinge via a quick-release mechanism.

[0006] Preferably, the end of the rotating arm away from the first hinge member is provided with an opening groove, and slots are provided through the two side walls of the opening groove; The quick-release mechanism includes an insert arm that slides through the slot and an elastic element that pulls the insert arm into the slide groove. The insert arm has a protruding flange that can abut against the outer wall of the rotating arm, and the end of the insert arm away from the slot has a pull ring.

[0007] Preferably, a strip-shaped through groove is provided on the insert arm in the same length direction, and a limiting bolt passing through the strip-shaped through groove is installed on the rotating arm.

[0008] Preferably, the elastic element is a tension spring whose two ends are respectively connected to the insert arm and the rotating arm.

[0009] Preferably, the pull ring portion is oriented towards the handle.

[0010] Preferably, the trolley is equipped with a shelf located above the power supply battery.

[0011] Preferably, both the first hinge and the second hinge are hinged to the end of the peeling chain via hinge bolts.

[0012] According to the above technical solution, the portable tree bark peeling machine provided by this utility model has the following beneficial effects during use: Firstly, the peeling chain is looped around the tree, and then the second hinge is connected to the rotating arm via a quick-release mechanism. Pulling the handle tightens the peeling chain, and the motor starts, driving the rotating arm to rotate reciprocally, thereby moving the peeling chain to scrape off the old bark. Compared with the traditional manual pulling of the peeling chain, this method is more labor-saving. At the same time, the operator can drive the stepper motor to move the peeling chain on the tree surface through the handle, and the operator can also walk around the tree, making the peeling work highly efficient. Secondly, a hanging rope can be attached to the mounting frame, allowing operators to hang the rope during use, thus reducing the burden on their hands.

[0018] like Figure 1-2 As shown, a portable tree peeling machine includes: a trolley 1, a power supply battery 2 mounted on the trolley 1, a mounting frame 3, a handle 4 fixedly connected to the mounting frame 3, a stepper motor 5 fixedly mounted on the mounting frame 3, a rotating arm 6 fixedly connected to the output shaft of the stepper motor 5 in the center, and a peeling chain 7. One end of the peeling chain 7 is hinged to one end of the rotating arm 6 via a first hinge 8, and the other end of the peeling chain 7 is equipped with a second hinge 9. The second hinge 9 is detachably connected to the end of the rotating arm 6 away from the first hinge 8 via a quick-release mechanism.

[0019] In the above technical solution, the power supply battery 2 is connected to the stepper motor 5 through a connecting cable. The connecting cable can be about 5-10 meters long, which is convenient for the operator to rotate around the tree and also convenient for the operator to peel the bark off the trees around the cart 1. The appropriate length of the connecting cable can be rotated according to the specific use environment. The peeling chain 7 is looped around the tree, and the second hinge 9 is connected to the rotating arm 6 via a quick-release mechanism. At this point, both ends of the peeling chain 7 are connected to both ends of the rotating arm 6. Then, the operator pulls the handle 4 away from the tree to tighten the peeling chain 7. The operator's hands hold the handle 4, which also controls the stepper motor 5. When the motor starts, it drives the rotating arm 6 to rotate back and forth, thereby moving the peeling chain 7 to scrape off the old bark. Compared with the traditional method of manually pulling the peeling chain 7, this method is more labor-saving. At the same time, the operator can move the stepper motor 5 through the handle 4, thereby moving the peeling chain 7 on the surface of the tree. The operator can also walk around the tree. A hanging rope can be connected to the mounting bracket 3, allowing operators to hang the rope and reduce the burden on their hands.

[0020] The motor controller that controls the reciprocating rotation of the output shaft of stepper motor 5 is a mature existing technology. It generates an appropriate pulse sequence so that stepper motor 5 rotates in the desired direction and speed.

The end of the insert arm 11 away from the slot is provided with a pull ring portion 14.

[0022] In the above technical solution, pulling the pull ring 14 causes the insert arm 11 to move out of one of the slots, the second hinge 9 is inserted into the opening slot 10, and then the pull ring 14 is released, the elastic member 12 will drive the insert arm 11 to re-insert into the slot until the flange 13 abuts against the rotating arm 6, and the insert arm 11 can restrict the second hinge 9 in the opening slot 10. When it is necessary to separate the second hinge 9 from the rotating arm 6, simply pull the pull ring 14 again to move the second hinge 9 out of the opening slot 10. The operation is quick and convenient.

[0023] In a preferred embodiment of the present invention, a strip-shaped through groove 15 is provided through the insert arm 11 in the same length direction, and a limiting bolt 16 passing through the strip-shaped through groove 15 is mounted on the rotating arm 6.
