Description

Technical Field

[0001] This utility model relates to the field of pepper planting technology, specifically to a trunk whitening device for pepper tree frost protection. Background Technology

[0002] In the cultivation of Sichuan pepper trees, winter frost protection is one of the key measures to ensure their safe overwintering, and whitewashing the trunk is a common frost protection method. Whitewashing the trunk not only reflects sunlight and reduces the temperature difference between day and night, preventing frost cracking, but also effectively kills bacteria and insect eggs in the bark crevices, reducing pest and disease attacks, which is of great significance to the healthy growth of Sichuan pepper trees.

[0003] Traditional tree trunk whitewashing is mostly done manually. Operators need to hold a brush or spray bottle and repeatedly brush or spray whitewash around the tree trunk. This method has obvious drawbacks: on the one hand, manual brushing is labor-intensive, especially in large-scale pepper plantations, and the efficiency is extremely low, making it difficult to meet the needs of large-scale planting; on the other hand, manual operation is prone to uneven distribution of whitewash, with some areas being coated too thinly or missed, affecting the antifreeze and insect-proof effects.

[0004] Furthermore, the trunks of Sichuan pepper trees vary in thickness, and the trunk height differs depending on the age of the tree. This makes it difficult to precisely control the coating area during manual whitewashing, often resulting in insufficient whitewashing or excessive waste of whitewash liquid. Additionally, the whitewash liquid is mostly a viscous liquid, which easily splashes during manual application, not only soiling the operator's clothing but also wasting materials and increasing planting costs. To solve these problems, there is an urgent need for a device that can achieve mechanized and automated whitewashing operations to improve whitewashing efficiency and quality, reduce manual labor intensity, and adapt to the whitewashing needs of Sichuan pepper trees of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a trunk whitening device for protecting pepper trees from frost, so as to solve the problems of low efficiency and uneven coating of manual brushing in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a trunk whitening device for frost protection of pepper trees, comprising a movable base, a liquid tank for storing whitening liquid on the movable base, and a whitening mechanism for spraying whitening liquid around the trunk. A delivery pump is connected to the liquid tank, and the discharge end of the delivery pump is connected to the whitening mechanism. The whitening mechanism includes a vertical plate, a lifting plate, an arc-shaped frame, and an arc-shaped support plate. The vertical plate is fixedly installed on the movable base. The lifting plate is slidably connected to one side of the vertical plate and has a cylinder assembly at its bottom for driving its lifting and lowering. The arc-shaped frame is fixedly installed on the lifting plate and has an arc-shaped sliding cavity on its inner side wall. An arc-shaped guide block is provided on the outer side wall of the arc-shaped support plate, which slides with the arc-shaped sliding cavity. The arc-shaped support plate is slidably connected to the arc-shaped frame through the arc-shaped guide block. A driving mechanism for driving the arc-shaped support plate to move circumferentially along the arc-shaped sliding cavity is fixedly installed on the lifting plate.

[0007] Furthermore, multiple sets of nozzles arranged in a rectangular array are installed on the inner side wall of the arc-shaped support plate. A flow-dividing cavity is opened inside the arc-shaped support plate, and the multiple sets of nozzles are connected to the flow-dividing cavity. A delivery port connected to the flow-dividing cavity is opened on the outer side wall of the arc-shaped support plate. The output end of the delivery pump is connected to the delivery port through a high-pressure hose. The multiple sets of nozzles face the central axis of the arc-shaped support plate.

[0008] Furthermore, the drive mechanism includes a motor, a gear, and an arc-shaped rack. The motor is located at the bottom end of the lifting plate and its output end movably passes through the lifting plate and is fixedly connected to the gear.

After adjusting to the height of the arc-shaped support plate 7 and the area of ​​the trunk to be whitewashed, close the cylinder assembly.

[0023] When the delivery pump 3 is turned on, the whitewash in the liquid tank 2 is pressurized by the delivery pump 3 and sent into the diversion cavity of the arc-shaped support plate 7 through the high-pressure hose. Then, it is evenly sprayed onto the surface of the tree trunk by multiple sets of nozzles 10. Simultaneously, the motor 11 is started, and the motor 11 drives the gear 12 to rotate. The gear 12 meshes with the arc-shaped rack 13 on the outer side of the arc-shaped support plate 7, driving the arc-shaped support plate 7 to rotate along the arc-shaped sliding cavity 8 of the arc-shaped frame 6 through the arc-shaped guide block 9, so as to achieve 360° circumferential spraying of the tree trunk.

[0024] After the spraying is completed, turn off the motor 11 and the delivery pump 3 in sequence, reset the lifting plate 5 through the cylinder assembly, push the moving base 1 to the next pepper tree, and repeat the above operation.
