Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chainsaw technology, specifically relating to a chainsaw with automatic chain lubrication adjustment. Background Technology
[0002] In many fields such as timber processing, forestry logging, and construction, the chainsaw plays an indispensable role as a key cutting tool. The electric hand-held saw is mainly used for logging and timber processing. Its working principle is to cut trees by the lateral movement of L-shaped blades on the chain.
[0003] In existing chainsaws, the chain moves at high speed inside the wood during cutting, thus cutting the wood. During this process, the high-speed movement of the chain generates high temperatures, and blockages can also occur inside the chain, causing it to rotate slowly. Therefore, it is necessary to stop the machine and apply a layer of oil to the surface of the chain for lubrication. The current method of applying oil is usually to stop the machine and use a brush to apply oil, which easily leads to some areas being coated with too much oil and others being coated with too little oil. In the case of areas with too much oil, oil will drip onto the ground, resulting in a large amount of oil waste. Utility Model Content
[0004] The purpose of this invention is to provide an electric saw with automatic chain lubrication adjustment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric saw with automatic chain lubrication adjustment, comprising:
[0006] The chainsaw host has a guide plate on one side, and a chain is sleeved on the guide plate. The chainsaw host is equipped with a lubrication component for adjusting the lubrication of the chain. The electric slide rail of the lubrication component drives the pressure plate to squeeze the oil storage sponge, so that the lubricating oil stored in the oil storage sponge flows to the chain surface through the oil outlet hole to lubricate the chain.
[0007] A brush plate, located at the bottom of the oil outlet, is used to brush the surface of the chain to remove impurities.
[0008] Preferably, the lubrication assembly includes an oil tank and a sealing cap. The oil tank is located inside the electric saw main unit, and the sealing cap is sealed to an oil inlet located on the top of the oil tank. A filter screen is provided inside the oil inlet.
[0009] Preferably, the oil tank is connected to two sets of guide rods and the two ends of the pressure plate are slidably sleeved on the surface of the guide rods. The electric slide rails are provided in two sets and are respectively located on both sides of the oil tank. The two ends of the pressure plate are respectively connected to the sliders on the surfaces of the two sets of electric slide rails.
[0010] Preferably, the oil storage sponge is connected to the bottom of the pressure plate, and the oil outlet is provided in several groups, all located inside the bottom of the oil tank.
[0011] Preferably, the bottom of the pressure plate is connected to a connecting rod, and one end of the connecting rod slides through the oil shell and extends into a storage groove provided at the bottom of the oil shell.
[0012] Preferably, one end of the connecting rod located in the storage groove is connected to the brush plate, and several brushes are connected to the bottom of the brush plate.
[0013] Preferably, the brush plate surface is provided with a plurality of perforations.
[0014] Preferably, the surface of the chainsaw main unit is connected to a handle.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) The oil is supplied by the pressure plate squeezed by the electric slide rail to supply oil. The lubrication can be achieved according to the working condition of the electric saw. The lubricating oil in the oil sponge flows to the brush surface through the oil outlet hole, so that the brush plate and the oil outlet hole work together. While the brush plate brushes the chain surface to remove impurities, the lubricating oil flows out to lubricate the chain, thereby ensuring that all parts of the chain are evenly and appropriately lubricated and avoiding the waste of lubricating oil.
[0017] (2) A filter screen is installed in the oil inlet of the lubrication component to effectively filter impurities before the lubricating oil enters the oil storage sponge, prevent impurities from entering the oil shell, avoid impurities from clogging the oil outlet and affecting the lubrication effect, or enter between the chain and the guide plate to aggravate wear and reduce maintenance costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides, for example Figure 1-3 An automatically adjustable chain lubrication chainsaw, as shown, includes:
[0024] The chainsaw host 1 has a guide plate 2 on one side, and a chain 3 is sleeved on the guide plate 2. The chainsaw host 1 is equipped with a lubrication component 4 for adjusting the lubrication of the chain 3. The electric slide rail 5 of the lubrication component 4 drives the pressure plate 6 to squeeze the oil storage sponge 7, so that the lubricating oil stored in the oil storage sponge 7 flows to the surface of the chain 3 through the oil outlet hole 8 to lubricate the chain 3.
[0025] Brush plate 9 is located at the bottom of oil outlet hole 8 and is used to brush the surface of chain 3 to remove impurities.
[0026] The lubrication assembly 4 includes an oil housing 10 and a sealing cover 11. The oil housing 10 is located inside the electric saw host 1, and the sealing cover 11 is sealed inside the oil inlet 12 located on the top of the oil housing 10. The oil inlet 12 is equipped with a filter screen 13, which continuously filters the lubricating oil entering the oil storage sponge. When the filtered impurities are intercepted on the surface of the filter screen 13, the sealing cover 11 can be opened later to clean the impurities on the surface of the filter screen 13.
[0027] The oil tank 10 is connected to two sets of guide rods 14, and the two ends of the pressure plate 6 are slidably sleeved on the surface of the guide rods 14. The electric slide rail 5 is provided in two sets and is respectively located on both sides inside the oil tank 10. The two ends of the pressure plate 6 are respectively connected to the sliders on the surface of the two sets of electric slide rails 5. A high-performance rubber sealing ring or sealing gasket is installed between the slider and the slide rail of the electric slide rail 5. The rubber sealing ring or sealing gasket can effectively prevent lubricating oil from entering the interior of the electric slide rail 5.
[0028] The oil storage sponge 7 is connected to the bottom of the pressure plate 6, and the oil outlet 8 is provided in several groups and is located inside the bottom of the oil shell 10.
[0029] The bottom of the pressure plate 6 is connected to a connecting rod 15, and one end of the connecting rod 15 slides through the oil shell 10 and extends into the storage groove 16 provided at the bottom of the oil shell 10. After lubrication, the brush 17 can be reset into the storage groove 16 to avoid affecting the chain 3 when it is working.
[0030] One end of the connecting rod 15 located in the storage groove 16 is connected to the brush plate 9. Several brushes 17 are connected to the bottom of the brush plate 9. Several perforations 18 are provided on the surface of the brush plate 9. The pressure plate 6 can drive the connecting rod 15 to move downward synchronously, so that the brushes 17 come into contact with the chain 3 and lubricate the chain 3. The brushes 17 are made of nylon, which has high strength and wear resistance, and can reduce the friction between the brushes and the chain 3 during the cleaning process, further protecting the brushes 17.
[0031] The main body of the chainsaw 1 is connected to a handle 19, which makes it easy to lift the chainsaw for use.
[0032] When the chain saw with automatic chain lubrication adjustment needs to lubricate the chain 3, the chain saw is started and the chain 3 rotates at a low speed. At this time, the lubricating oil is stored naturally in the oil storage sponge. The electric slide rail 5 is started by controlling the control button on the surface of the chain saw host 1. The slider of the electric slide rail 5 drives the pressure plate 6 to move downward along the guide rod 14. The pressure of the pressure plate 6 on the oil storage sponge gradually increases. Under the action of pressure, the lubricating oil in the oil storage sponge flows to the surface of the brush plate 9 through the oil outlet hole 8 at the bottom of the oil shell 10, and then flows to the surface of the brush 17 through the drain hole 18 on the surface of the brush plate 9.
[0033] As the pressure plate 6 presses down on the oil storage sponge, the connecting rod 15 connected to the bottom of the pressure plate 6 moves downward synchronously. The connecting rod 15 slides in the storage groove 16 at the bottom of the oil shell 10 and drives the brush plate 9 to move downward. The brush 17 at the bottom of the brush plate 9 contacts the surface of the chain 3. During the low-speed rotation of the chain 3, the brush 17 brushes off the impurities on the surface of the chain 3. The lubricating oil on the surface of the brush 17 can be adsorbed on the surface of the chain 3 when it comes into contact with the chain 3, thus achieving automatic lubrication of the chain 3.
[0034] When the amount of lubrication needs to be increased, the electric slide rail 5 moves the slider downward, which increases the pressure applied by the pressure plate 6 to the oil storage sponge. This causes the lubricating oil stored in the oil storage sponge to be subjected to greater pressure, and more lubricating oil will flow through the oil outlet 8 at the bottom of the oil shell 10 to the surface of the chain 3, thereby increasing the lubrication effect. Conversely, when the amount of lubrication needs to be reduced, the electric slide rail 5 drives the slider upward, which reduces the pressure of the pressure plate 6 on the oil storage sponge, and the amount of lubricating oil flowing out decreases accordingly, thereby adjusting the output of lubricating oil.
[0035] After lubrication is completed, the slider of the electric slide rail 5 drives the pressure plate 6 to move upward to the initial position, releasing the pressure on the oil storage sponge. At this time, the lubricating oil stops flowing out. At the same time, the connecting rod 15 drives the brush plate 9 to move upward back to the initial height in the storage groove 16, and the brush 17 disengages from the chain 3.
[0036] After the brush 17 is reset, the sealing cover 11 can be opened to inject lubricating oil into the oil inlet 12 to prepare for the next lubrication. A certain amount of lubricating oil (such as 500ML) can be injected and it can be completely absorbed by the oil storage sponge 7. This avoids the lubricating oil leaking from the oil outlet 8 and being wasted because too much lubricating oil cannot be absorbed by the oil storage sponge 7. During the entire lubrication process, the filter screen 13 of the oil inlet 12 continuously filters the lubricating oil entering the oil storage sponge to ensure that the lubricating oil is clean and prevent impurities from entering the subsequent lubrication process.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
