Description

Technical Field

[0001] The utility model relates to a hydraulically driven oil cylinder for a potash fertilizer bucket wheel machine, belonging to the technical field of hydraulically driven oil cylinders. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion. It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides. The driven hydraulic cylinder is mainly used in the driving mechanism, and the hydraulic cylinder in the driving mechanism has a large workload. Hydraulic driven cylinders will be installed in potash bucket wheel excavators.

[0003] There are still some problems in the use of the existing hydraulically driven cylinder of a potash fertilizer bucket wheel excavator. When the hydraulically driven cylinder is used for a long time, a large amount of high temperature will be generated inside it. If the hydraulically driven cylinder is not cooled in time, the service life of the hydraulically driven cylinder will be affected. In addition, oil stains will be adsorbed on both sides of the hydraulically driven cylinder, which is more troublesome to clean. Utility Model Content

[0010] Furthermore, the refrigerator and the telescopic hose are symmetrically distributed on the top of the oil cylinder body, and one end of the telescopic hose away from the refrigerator is fixedly connected to the inside of the sliding ring.

[0011] Furthermore, the clamping blocks are symmetrically distributed on the outside of the sliding ring, and the stabilizing rod is located inside the positioning hole.

[0012] Furthermore, the bottom of the compression spring is fixedly connected to the top of the movable tube, and the cleaning plate is slidably connected to the outside of the oil cylinder body.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model is provided with a cylinder body. When the cylinder body needs to be cooled, the motor and the refrigerator on the outside of the connecting plate are started simultaneously through an external control device. At this time, the cold air generated by the refrigerator will enter the interior of the sliding ring through the telescopic hose. Since an air outlet is provided in the inner wall of the sliding ring, the cold air will reach the surface of the cylinder body, thereby cooling the cylinder body. The motor then drives the screw rod to rotate, and the rotation of the screw rod drives the rotating ring to rotate. Since a moving rod is fixedly connected to the bottom of the rotating ring, and the sliding ring is slidably connected to the outside of the cylinder body through the moving rod, the sliding ring will limit the rotating ring. Therefore, when the screw rod rotates, it can drive the rotating ring to move on its outside.

The L-shaped plate on the outside of the clamping block cooperates with the connecting rod to make the cleaning plate slide on the outside of the oil cylinder body. At this time, the oil stains attached to the outside of the oil cylinder body can be cleaned. When the cleaning plate needs to be cleaned, the stabilizing rod is driven to move upward inside the movable tube by pulling the cover, so that the bottom of the stabilizing rod is moved out of the positioning hole of the L-shaped plate. At this time, the L-shaped plate can be moved out from the inside of the clamping block, and the cleaning plate after cleaning the oil stains can be cleaned for next use.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1 Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A hydraulically driven oil cylinder for a potash bucket wheel excavator comprises an oil cylinder body 1, an oil filling pipe 2 is fixedly connected to the top of the oil cylinder body 1, a connecting plate 3 is fixedly connected to the top of the oil cylinder body 1, a motor 4 is fixedly connected to the outer side of the connecting plate 3, a screw rod 5 is fixedly connected to the output end of the motor 4, a rotating ring 6 is threadedly connected to the outer side of the screw rod 5, a moving rod 7 is fixedly connected to the bottom of the rotating ring 6, a sliding ring 8 is fixedly connected to the bottom of the moving rod 7, an air outlet 9 is opened inside the sliding ring 8, a refrigerator 10 is fixedly connected to the top of the oil cylinder body 1, and a telescopic hose 11 is fixedly connected to the outer side of the refrigerator 10.

[0025] Specifically, Figure 1 As shown, the connecting plates 3 are symmetrically distributed on the top of the cylinder body 1, the screw rod 5 is rotatably connected between the two connecting plates 3, the sliding ring 8 is slidably connected to the outside of the cylinder body 1, the air outlet holes 9 are evenly distributed in the inner wall of the sliding ring 8, and the interior of the sliding ring 8 is hollow, the refrigerator 10 and the telescopic hose 11 are symmetrically distributed on the top of the cylinder body 1, and the end of the telescopic hose 11 away from the refrigerator 10 is fixedly connected to the inside of the sliding ring 8.

[0026] In this embodiment: by setting up the cylinder body 1, when the cylinder body 1 needs to be cooled, the motor 4 and the refrigerator 10 on the outside of the connecting plate 3 are started at the same time through the external control device. At this time, the cold air generated by the start-up of the refrigerator 10 will enter the interior of the sliding ring 8 through the telescopic hose 11. Since an air outlet 9 is provided in the inner wall of the sliding ring 8, the cold air will reach the surface of the cylinder body 1, thereby cooling the cylinder body 1, and then the motor 4 drives the screw rod 5 to rotate, and the rotation of the screw rod 5 drives the rotating ring 6 to rotate. Since a moving rod 7 is fixedly connected to the bottom of the rotating ring 6, and the sliding ring 8 is slidably connected to the outside of the cylinder body 1 through the moving rod 7, the sliding ring 8 will limit the rotating ring 6. Therefore, when the screw rod 5 rotates, it can drive the rotating ring 6 to move on its outside. By using the rotating ring 6 and the moving rod 7 in coordination, the sliding ring 8 slides on the outside of the cylinder body 1, and the cylinder body 1 can be evenly cooled.

[0027] Example 2 Please refer to Figure 1 , Figure 2 and Figure 4The difference between this embodiment and embodiment 1 is that: a clamping block 12 is fixedly connected to the outer side of the sliding ring 8, an L-shaped plate 13 is installed inside the clamping block 12, a positioning hole 14 is opened inside the L-shaped plate 13, a movable tube 15 is fixedly connected to the top of the clamping block 12, a stabilizing rod 16 is movably connected inside the movable tube 15, a pulling cover 17 is fixedly connected to the top of the stabilizing rod 16, a compression spring 18 is fixedly connected to the bottom of the pulling cover 17, a connecting rod 19 is fixedly connected to the inner side of the L-shaped plate 13, and a cleaning plate 20 is fixedly connected to the outer side of the connecting rod 19.

[0028] Specifically, Figure 1-4 As shown, the clamping blocks 12 are symmetrically distributed on the outside of the sliding ring 8, the stabilizing rod 16 is located inside the positioning hole 14, the bottom of the compression spring 18 is fixedly connected to the top of the movable tube 15, and the cleaning plate 20 is slidably connected to the outside of the cylinder body 1.

[0029] In the present embodiment: by providing a sliding ring 8, when the sliding ring 8 slides on the outside of the cylinder body 1 to cool down the cylinder body 1, the sliding ring 8 will drive the clamping block 12 to move, and the L-shaped plate 13 on the outside of the clamping block 12 cooperates with the connecting rod 19 to make the cleaning plate 20 slide on the outside of the cylinder body 1. At this time, the oil stains attached to the outside of the cylinder body 1 can be cleaned. When the cleaning plate 20 needs to be cleaned, the stabilizing rod 16 is driven to move upward inside the movable tube 15 by pulling the cover 17, so that the bottom of the stabilizing rod 16 is moved out of the positioning hole 14 of the L-shaped plate 13. At this time, the L-shaped plate 13 can be moved out from the inside of the clamping block 12, and the cleaning plate 20 after cleaning the oil stains can be cleaned for next use.
