Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an oil dripping device for use on garlic harvesters. Background Technology

[0002] During garlic seed harvesting, the clamping device is responsible for clamping and lifting the garlic sprouts. It typically contains multiple transmission chains that work in conjunction with sprockets to achieve synchronous transmission. The applicant has disclosed an adjustable row spacing clamping mechanism structure and its synchronous belt transmission scheme in its published patent CN119096788A. This scheme effectively improves adaptability to different planting row spacings.

[0003] However, under the long-term field operation conditions of garlic harvesters, garlic leaves, soil, straw fragments, and other debris easily adhere to the meshing areas of the transmission chain and sprockets in multiple locations of the clamping device. When this debris mixes with the lubricating oil, it often clumps together, leading to abnormal chain tension, inflexible chain link rotation, abnormal chain tightness, and even chain buckling. Simultaneously, traditional methods relying on manual, timed spraying or centralized grease lubrication are difficult to apply in a timely, quantitative, and even manner to the gaps between the chain sleeve pins. This is not only labor-intensive but also results in unstable lubrication under machine vibration and dusty conditions. Currently, there is a lack of a dedicated oil dripping device in garlic harvesting equipment that is simple in structure, can be fixed locally to the clamping device, allows for adjustable dripping speed, and can directionally drip lubricant onto key chain segments.

[0004] Based on this, the applicant has made improvements to its existing equipment and proposed a chain oiling device that matches the structure of the clamping device, is powered by 12V to drive the oil pump, and can achieve fine adjustment of the dripping speed by turning the nut, in order to solve the problems of chain buckling caused by debris caking, untimely and uneven lubrication. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an oil dripping device for use on garlic harvesters.

[0006] An oil dripping device for use on a garlic harvester includes an oil nozzle, a switch, an oil pump, and a power supply, characterized in that: The fuel injector is connected to the fuel pump and is positioned toward the drive chain inside the clamping device. The switch is used to control the fuel pump to be powered by the power supply. The fuel injector's outlet end is equipped with a throttling device that adjusts the dripping speed by turning the nut to change the oil passage gap.

[0007] Furthermore, in order to better realize the present invention, the fuel injector is fixed to the frame of the clamping device and aligned with the meshing area of ​​the chain and sprocket.

[0008] Furthermore, in order to better realize the present invention, the fuel injectors are arranged in one or more parallel connections and supplied with fuel by the same fuel pump.

[0009] Furthermore, in order to better realize the present invention, the nut of the fuel injector is a self-locking structure to prevent drip rate drift under vibration.

[0010] Furthermore, to better realize the present invention, the switch is a waterproof structure and is provided with a detachable electrical connection between it and the oil pump for maintenance.

[0011] Furthermore, in order to better realize the present invention, the oil pump is a low-pressure, low-flow pump, which is suitable for pushing the lubricant to the injector in droplets.

[0012] Furthermore, in order to better realize the present invention, the power supply is connected to the 12V power system of the whole machine and the oil pump is started and stopped by a switch.

[0013] Furthermore, in order to better realize the present invention, the fuel injector and the fuel pump are connected by a flexible oil pipe, and the fuel injector is detachable for cleaning.

[0014] A garlic harvester includes a clamping device, characterized in that: the clamping device is provided with an oil dripping device, so that lubricant is applied to the transmission chain in a droplet-like directional manner during operation. The beneficial effects of this invention are: The drip rate is continuously adjustable via the throttling at the nozzle tip, adapting to various working conditions such as dry dust and post-rain mud. The nozzle is aligned with the critical meshing area of ​​the chain, allowing oil droplets to penetrate more easily into the sleeve-pin clearance, reducing dry friction and abrasive wear. The oil pump, nozzle, switch, and power supply form a low-cost add-on module that can be directly fixed to existing clamping devices without altering the main structure. This prevents chain buckling and jamming caused by debris buildup, extending the life of the chain and sprockets and improving overall machine uptime. Attached Figure Description

The switch 2 is electrically connected to the power supply 4 to drive the oil pump as needed. The nozzle 1 is arranged facing the chain, and the oil outlet adopts a nut-type throttling structure: the operator changes the oil passage gap by turning the nut to obtain the required dripping speed. During operation, the switch 2 is turned on, and the oil pump 3 draws power from the power supply 4 to push the lubricant to the nozzle 1, and the oil droplets fall directionally into the meshing area of ​​the chain and sprocket.

[0021] Multiple fuel injectors 1 can be arranged on one device and connected in parallel to the same oil pump 3 to drip oil onto multiple chains respectively; each fuel injector 1 can be independently set with its own nut to adapt to different chain loads and contamination levels.

[0022] The distance and direction of the fuel injector 1 relative to the chain can be adjusted by the mounting holes or the angle and gap of the connectors to ensure that the fuel droplets enter the gaps between the chain links as much as possible; the switch 2 can be located in a position easily accessible to the operator; the power supply 4 is preferably connected to the machine's 12V power system. During maintenance, simply unscrew the nut at the end of the fuel injector 1 to clean the channel and restore a stable dripping rate.
