Description

Technical Field

[0001] The present application relates to the technical field of chain arm saws, and in particular to a lubricating oil tank for a chain arm saw and a chain arm saw. Background Art

[0002] The chain arm saw is a mechanical arm device equipped with a chain saw blade. It is usually used in infrastructure construction such as foundation pit excavation, tunnel excavation and mining. The chain arm saw combines the flexibility of the mechanical arm with the efficient cutting ability of the chain saw, making the operation more convenient and safe. It is an efficient stone processing machinery.

[0003] The prior art discloses a wheel chain arm saw, comprising: a wheel drive machine, a transmission device and a chain arm, wherein the transmission device is arranged between the wheel drive machine and the chain arm, a position adjustment device for changing the position of the chain arm is arranged between the transmission device and the wheel drive machine, the position adjustment device is detachably connected to the wheel drive machine through a connecting piece, and a swing device for changing the cutting angle of the chain arm is arranged between the chain arm and the transmission device.

[0004] In order to facilitate cutting, the direction of the blade arm of the chain arm saw is generally set to an adjustable structure. In order to ensure the smoothness of the adjustment of the blade arm direction, the rotating shaft, chain and other positions on the chain arm saw need to be lubricated. In the prior art, an iron lubricating oil tank is usually fixed on the side wall of the casing. The lubricating oil tank is filled with lubricating oil. The lubricating oil tank supplies oil to the positions of the parts that need lubrication on the chain arm saw. However, as the lubricating oil is placed for a longer time, the lubricating oil in the lubricating oil tank is more likely to precipitate. The precipitated lubricating oil will affect the passability of the lubricating oil tank outlet, greatly reducing the speed at which the lubricating oil drips from the outlet under the action of gravity, thereby affecting the lubrication effect of the chain arm saw. Utility Model Content

[0005] In order to reduce the influence of the precipitation of lubricating oil in the lubricating oil tank on the lubrication effect of the chain arm saw, the present application provides a lubricating oil tank and a chain arm saw for a chain arm saw.

[0006] The present application provides a lubricating oil tank for a chain arm saw and a chain arm saw adopting the following technical solution:

[0007] In a first aspect, the present application provides a lubricating oil tank for a chain arm saw.

[0008] A lubricating oil tank for a chain arm saw, comprising:

[0009] A box body having a receiving cavity;

[0010] A rotating shaft, the rotating shaft is rotatably connected to the housing, and a stirring paddle is connected to the extending section of the rotating shaft extending into the inner cavity of the housing, and the stirring paddle is staggered with the housing along the radial direction of the rotating shaft;

[0011] A driving unit for driving the rotating shaft to rotate, wherein the driving unit is connected to the box body, and the driving unit is connected to a protruding section of the rotating shaft extending out of the box body.

[0012] By adopting the above technical solution, after the chain arm saw has been working for a period of time, it is necessary to lubricate and maintain the steering structure or transmission structure on the chain arm saw. At this time, the lubricating oil in the box is discharged from the box under its own gravity or driven by an external drive such as a lubricating oil pump and drips onto the steering structure or the transmission structure. As the use time increases, the lubricating oil in the box begins to precipitate. When the precipitation affects the discharge speed of the lubricating oil, the driving unit applies force to the rotating shaft, and the rotating shaft drives the stirring paddle to rotate. The rotation of the stirring paddle drives the lubricating oil precipitated in the box to move, so that the lubricating oil can be smoothly discharged from the oil outlet of the box for lubrication. The lubricating oil tank designed for the chain arm saw can accommodate the lubricating oil through the box, and the power of the driving unit can be transmitted to the stirring paddle located in the box through the rotating shaft. The lubricating oil precipitated in the box can be stirred by the stirring paddle, so as to facilitate the discharge of the lubricating oil from the outlet of the box for lubrication, thereby reducing the influence of the precipitation of the lubricating oil in the lubricating oil tank on the lubrication effect of the chain arm saw.

[0013] In a specific embodiment, the housing includes

[0014] A cylinder body, wherein the cylinder body is hollow and has openings at both axial ends;

[0015] A bottom cover and a blocking top cover are installed, wherein the bottom cover and the blocking top cover are respectively connected to the axial ends of the cylinder and are used to block the end opening of the cylinder, and the blocking top cover is located above the bottom cover.

[0016] By adopting the above technical solution, a box body is designed, which can form a accommodating chamber for containing lubricating oil through the cylinder body, the installed bottom cover and the sealed top cover. The detachable fixed connection with the chain arm saw body can be achieved by installing the bottom cover.

[0017] In a specific possible implementation manner, the cylinder is made of a transparent material.

[0018] By adopting the above technical solution, the design material is selected as a transparent material cylinder, which can facilitate the staff to observe the amount of lubricating oil in the cylinder, so as to control the amount of lubricating oil replenished or replenish the lubricating oil in time.

[0019] In a specific possible implementation manner, a plurality of reinforcing protection rods are connected between the installation bottom cover and the blocking top cover, and the plurality of reinforcing protection rods form a placement cavity for accommodating the cylinder.

[0020] By adopting the above technical solution, the reinforced protective rod designed can reduce the possibility of long flying branches causing damage to the cylinder during the operation of the chain arm saw, and can also limit the cylinder when the sealing top cover is removed to add lubricating oil.

[0021] In a specific possible implementation mode, the reinforcing protection rod is detachably fixedly connected to the blocking top cover.

[0022] By adopting the above technical solution, a reinforced protective rod is designed to be detachably fixedly connected to the sealing top cover. Since the viscosity of the lubricating oil is relatively high, the sealing top cover can be removed when adding the lubricating oil to facilitate the addition of the lubricating oil.

[0023] In a specific possible implementation manner, a lifting handle is connected to the sealing top cover.

[0024] By adopting the above technical solution, the designed lifting handle can facilitate the removal of the connection between the reinforcing protection rod and the blocking top cover, and then apply force to the blocking top cover to facilitate the separation of the blocking top cover from the cylinder body, and facilitate the holding of the blocking top cover.

[0025] In a specific possible implementation manner, at least one stirring rod is connected to the stirring paddle, the stirring rod is arranged along the axial direction of the cylinder, and the stirring rod is arranged close to the inner circumference of the cylinder.

[0026] By adopting the above technical solution, the stirring rod designed to be arranged along the axial direction of the cylinder can increase the stirring force and mixing degree of the lubricating oil inside the cylinder when the viscosity of the lubricating oil is large, so as to facilitate the mixing of the precipitated lubricating oil and the unprecipitated lubricating oil.

[0027] In a second aspect, the present application provides a chain arm saw.

[0028] A chain arm saw comprises a chain arm saw body and a lubricating oil tank for the chain arm saw. The lubricating oil tank for the chain arm saw is installed on the chain arm saw body.

[0029] By adopting the above technical solution, the designed chain arm saw can stir the lubricating oil in the lubricating oil tank, thereby reducing the influence of the sedimentation of the lubricating oil in the lubricating oil tank on the lubrication effect of the chain arm saw.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The lubricating oil tank designed for the chain arm saw can contain lubricating oil through the box body, and the power of the driving unit can be transmitted to the stirring paddle in the box body through the rotating shaft. The lubricating oil precipitated in the box body can be stirred by the stirring paddle, so that the lubricating oil is discharged from the outlet of the box body for lubrication, thereby reducing the influence of the precipitation of the lubricating oil in the lubricating oil tank on the lubrication effect of the chain arm saw.

[0032] 2. The lubricating oil tank designed for the chain arm saw is made of a transparent material, which makes it easy for the staff to observe the amount of lubricating oil in the cylinder, so as to control the amount of lubricating oil to be replenished or replenish the lubricating oil in time.

[0033] 3. The lubricating oil tank designed for the chain arm saw has a reinforced protective rod detachably fixedly connected to the blocking top cover. Since the viscosity of the lubricating oil is relatively large, the blocking top cover can be removed when adding the lubricating oil to facilitate the addition of the lubricating oil.

[0042] Reference Figure 2 When the viscosity of the lubricating oil is relatively high, in order to increase the stirring force and mixing degree of the lubricating oil inside the cylinder 11, so as to facilitate the mixing of the precipitated lubricating oil and the unprecipitated lubricating oil, at least one stirring rod 6 is connected to the stirring paddle 3, and the axial direction of the stirring rod 6 is consistent with the axial direction of the cylinder 11, and the stirring rod 6 is arranged close to the inner circumference of the cylinder 11; in the present application, the stirring rod 6 and the stirring paddle 3 can be welded and fixed, or they can be fixed by bolts. In order to ensure the structural strength of the connection between the stirring rod 6 and the stirring paddle 3, the stirring rod 6 is arranged through the stirring paddle 3 and is welded and fixed.

[0043] Reference Figure 2 In order to drive the stirring paddle 3 to rotate through the rotating shaft 2, the lubricating oil tank for the chain arm saw also includes a driving unit 4 for driving the rotating shaft 2 to rotate, the driving unit 4 is connected to the box body 1, and the driving unit 4 is connected to the extending section of the rotating shaft 2 extending out of the accommodating cavity of the box body 1; in the present application, the driving unit 4 can be a rotating handle, and when the lubricating oil precipitated in the box body 1 needs to be stirred, the stirring is achieved by manually driving the rotating handle to rotate, and the driving unit 4 can also be a rotating motor, the rotating motor is bolted to the box body 1, and the output shaft of the rotating motor is connected to the rotating shaft 2 through a coupling, in order to control the installation direction of the rotating motor, the rotating motor and the rotating shaft 2 can also change the reverse direction of the torque and achieve connection through a reduction box; in this embodiment, in order to reduce the labor intensity of human labor, the driving unit 4 is configured as a combination structure of a rotating motor and a reduction box.

[0044] Reference Figure 3 The box body 1 includes a cylinder 11, a mounting bottom cover 12 and a blocking top cover 13. The cylinder 11 is hollow and both axial ends of the cylinder 11 are opened. The mounting bottom cover 12 and the blocking top cover 13 are respectively connected to the axial ends of the cylinder 11 to block the openings at both axial ends of the cylinder 11, and the blocking top cover 13 is located above the mounting bottom cover 12. In order to facilitate the staff to observe the amount of lubricating oil in the cylinder 11, so as to control the amount of lubricating oil replenished or replenish the lubricating oil in time, the cylinder 11 is set to a transparent material, such as tempered glass, acrylic, or other hard and transparent materials.

[0045] Reference Figure 3In order to reduce the possibility of damage to the cylinder 11 by long flying branches during the operation of the chain arm saw, the cylinder 11 can also be limited when the blocking top cover 13 is removed to add lubricating oil, and multiple reinforcing protection rods 14 are connected between the bottom cover 12 and the blocking top cover 13.

[0047] The implementation principle of a lubricating oil tank for a chain arm saw in an embodiment of the present application is as follows: after the chain arm saw has been working for a period of time, the steering structure or the transmission structure on the chain arm saw needs to be lubricated and maintained. At this time, the lubricating oil in the box body 1 is discharged from the box body 1 and drips onto the steering structure or the transmission structure under its own gravity or an external drive such as a lubricating oil pump. As the use time increases, the lubricating oil in the box body 1 begins to precipitate. When the precipitation affects the discharge speed of the lubricating oil, the drive unit 4 applies force to the rotating shaft 2, and the rotating shaft 2 drives the stirring paddle 3 to rotate. The rotation of the stirring paddle 3 drives the lubricating oil precipitated in the box body 1 to move, so that the lubricating oil can be smoothly discharged from the oil outlet of the box body 1 for lubrication.
