The utility model discloses a pomelo fruit collecting and transferring device with buffering and damping functions, which relates to the technical field of fruit picking and mainly comprises a top buffering part for collecting pomelo fruits and a bottom adjusting part for adjusting the height of the buffering part. On the aspect of buffering and damping, buffering folding cloth between a first buffering piece and a second buffering piece is ingeniously utilized, the buffering columns with the inner walls made of rubber materials and the interiors filled with air are matched, the impact force generated when pomelo fruits fall off during picking is effectively weakened, and the situation that the quality is affected due to falling damage and breaking is avoided; after picking is finished, the support is separated from the trunk, the reset spring pushes the collecting frame to the circle center of the support, the pomelo fruits automatically fall into the collecting frame, manual secondary transfer is not needed, the process is greatly simplified, and the working efficiency is improved. In height adjustment, the position of the buffer part can be flexibly adjusted according to the height of the pomelo tree, the pomelo falling height is effectively controlled, and the damage risk is reduced.

The application discloses a kind of anti-insect nets for shatian pomelo trees, including: fixing belt, buckle, support rod, unfolding rod, anti-insect net and edge elastic band, compared with existing anti-insect nets, the application can quickly complete installation and disassembly, and is installed on the trunk without being affected by the terrain, and can protect from the roots of the tree to the anoplophora chinensis and anoplophora chinensis larvae, the double-layer structure design of the anti-insect net can hook the feet of adult insects with the convex semicircular structure and serve as the second layer of protection of the outer net, and the outer net sticks the larvae or adult insects with small mesh fish silk net, effectively preventing anoplophora chinensis from damaging fruits.

This utility model relates to the field of high-branch pruning technology and discloses a telescopic mechanism for high-branch pruning of pomelo trees. It includes a base, a fixed cylinder fixedly connected to the top of the base, an adjusting rod slidably disposed inside the fixed cylinder, and a locking bolt threaded through the outer wall of the fixed cylinder. This utility model's technical solution, through the cooperation of the fixed cylinder, locking bolt, and adjusting rod, allows for the adjustment and fixation of the mounting frame height, accommodating workers of different heights. The rotating adjusting cylinder inside the mounting frame, in conjunction with the set screw, enables the installation and fixation of the electric push rod. Furthermore, under the action of the rotating adjusting cylinder and the rotating shaft, multi-angle adjustment of the electric push rod can be achieved, improving the flexibility of use. Through the cooperation of these structures, high-branch pruning eliminates the need for personnel to manually hold the electric push rod, thus avoiding prolonged lifting movements that could cause arm pain and improving pruning efficiency.

The utility model relates to pomelo water and fertilizer mixing technical field discloses a pomelo planting water and fertilizer mixing device, including mixing bin, the mixing bin front end fixedly connected with the discharge pipe and penetrates, the discharge pipe inner fixedly connected with the fixed ring, the mixing bin bottom fixedly connected with the drive motor, drive motor drive end is connected with the connecting frame and transmission rod through stirring group, the fixed ring top end outer wall installs the discharge bin, the discharge bin outer wall fixedly connected with a plurality of filter screen, the discharge bin left and right two ends are connected with the clamping block through the installation group. In the utility model, effectively avoid the problem that the discharge pipe is blocked possibly after the undissolved impurity in the fertilizer flows into the irrigation system with the mixed solution, ensure to carry out water and fertilizer integrated irrigation operation continuously and stably, guarantee pomelo tree to get timely, sufficient precision nutrient supply, improve pomelo planting's fertilization efficiency, satisfy precision fertilization demand.

This invention discloses a simulation method for droplet deposition characteristics during orchard multi-duct spraying, relating to the field of plant protection spraying simulation technology. The invention includes: S1, acquiring parameters of the pomelo tree canopy and the air-assisted sprayer as first simulation parameters; S2, constructing a fan blade slip network model, a moving fan area overlapping grid, a porous media canopy, and a canopy droplet capture model based on the first simulation parameters; S3, constructing a three-dimensional computational domain model by combining the fan blade slip grid model, the moving fan area overlapping grid, and the porous media canopy model, and performing mesh generation; S4, setting second simulation parameters for the pomelo tree canopy spraying simulation; S5, performing simulation statistics and analyzing the flow field distribution and droplet deposition patterns within the canopy by combining the second simulation parameters, the meshed three-dimensional computational domain model, and the canopy droplet probability capture model. This invention significantly improves the accuracy of pesticide application simulation for dense canopy fruit trees such as pomelo.

The invention discloses a night insect prevention device for grapefruit tree planting, and relates to the technical field of orchard insect pest control. The device comprises a supporting seat, and a splicing mechanism and a matching mechanism are arranged on one side of the supporting seat; the splicing mechanism comprises at least four sets of supporting frames arranged on one side of the supporting base, the supporting frames are annularly arranged, and sliding grooves are formed in the tops of the supporting frames, so that the insect-proof net is changed into a covering state from a rolling state, it is ensured that the whole grapefruit tree is covered, and pests are prevented from entering the grapefruit tree through the insect-proof net. The physical barrier can effectively reduce insect attack, improve the growth environment quality of grapefruit trees and avoid fruit damage caused by insect attack, meanwhile, the humidity sensor can monitor the humidity in the insect-proof net in real time, and the height of the supporting frame is automatically adjusted according to the change of the humidity. When the humidity is high, the supporting frame can automatically rise, and therefore moisture accumulation caused by the fact that the insect-proof net is too low is avoided. Excessive moisture can promote breeding of germs, and the risk of diseases of the grapefruit trees is increased.
