Description

Technical Field

[0001] This utility model relates to the field of chestnut orchard management technology, specifically a multi-functional integrated machine for weeding and loosening soil in chestnut orchards. Background Technology

[0002] In modern agricultural production, the daily management of chestnut orchards plays a crucial role in the yield and quality of chestnuts. Weeding and loosening the soil are two important and time-consuming tasks.

[0003] Traditional methods of weeding in chestnut orchards rely on manual weeding or the use of backpack sprayers to spray herbicides. Manual weeding is extremely inefficient and cannot meet the management needs of large-scale chestnut orchards. Backpack sprayers have problems such as small spraying range, high labor intensity, and uneven spraying, which can easily lead to incomplete weeding. In addition, manual operation may result in accidental spraying of pesticides, which can affect the growth of chestnut trees.

[0004] Traditional methods for loosening soil often involve manual hoeing or using a small tractor with a fixed loosening device. Manual hoeing is inefficient, difficult to penetrate the soil, and has limited effectiveness. The fixed loosening device on the small tractor is not flexible enough to be effectively adjusted according to different soil conditions and chestnut tree planting spacing, and it is easy to damage the chestnut tree root system. In addition, existing chestnut orchard management equipment has limited functionality, and weeding and loosening soil need to be done in stages with different equipment, which not only increases the cost of equipment purchase, but also prolongs the operation time and reduces production efficiency due to frequent equipment changes. In view of this, we propose a multi-functional integrated machine for weeding and loosening soil in chestnut orchards. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional integrated machine for weeding and loosening soil in chestnut orchards. By setting up a soil loosening mechanism, a mobile weeding mechanism, and a liquid supply mechanism, it solves the problems of low efficiency and small coverage area and poor effect of fixed nozzles in traditional chestnut orchard operations, which require separate soil loosening and weeding processes.

The liquid supply mechanism 4 also includes an inlet funnel 42 fixed on the top surface of the liquid supply tank 41 and communicating with its inner cavity, and a manual valve 43 installed on the outer wall of the inlet funnel 42 pipe. The outlet end of the pump body 44 is tightly connected with a liquid pipe 45 that penetrates the right side surface of the liquid supply tank 41, and the liquid pipe 45 is connected to the inlet pipe 36 through a corrugated pipe 46.

[0051] The liquid supply mechanism 4, consisting of the liquid supply tank 41 and the pump body 44, continuously and stably supplies the liquid to the liquid box 31; the liquid inlet funnel 42 and the manual valve 43 facilitate the addition and control of the liquid, and the corrugated pipe 46 ensures the stability of the pipeline connection during movement.

[0053] The sealing rings at the joints of each component enhance the sealing performance of the integrated liquid delivery system, preventing liquid leakage, reducing waste, and avoiding environmental pollution; at the same time, they ensure stable system pressure and ensure that the nozzle 33 sprays the medicine continuously and evenly.

[0054] It should be added that the electric cylinder 22, the soil loosening motor 26, the moving motor 312, and the pump body 44 are all electrically connected to the external PLC via wires.

The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0056] In this embodiment, when soil loosening is required, the external PLC sends a command to start the electric cylinder 22, whose piston rod extends, driving the frame 21 and the loosening roller 24 to move down to the set depth. Then, the external PLC controls the loosening motor 26 to run, driving the rotating roller 23 to drive the loosening blade 25 to rotate at high speed, breaking and loosening the soil in the chestnut orchard.

[0057] After loosening the soil, weeding is carried out. The external PLC first starts the pump body 44, which transports the liquid in the supply tank 41 to the liquid box 31 through the liquid pipe 45 and the corrugated pipe 46, and then sprays it out from the nozzle 33 through the outlet pipe 32. At the same time, the PLC controls the moving motor 312 to rotate, which drives the rotating column 38 and the screw 39 to rotate, and drives the connecting plate 310 to move back and forth along the horizontal end of the U-shaped plate 37, so that the nozzle 33 makes a linear reciprocating motion in the front and back direction, expanding the spray coverage area.

[0058] After the operation is completed, the external PLC sends a stop command to shut down the moving motor 312, the pump body 44, and the loosening motor 26 in sequence, and controls the electric cylinder 22 to retract, lifting and resetting the loosening roller 24. The whole process realizes automated and precise operation, and efficiently completes the loosening and weeding work in the chestnut orchard.
