Description

Technical Field

[0001] This utility model relates to the field of articulated arm mechanism technology, specifically an articulated arm mechanism for improving the stirring and oscillating stroke. Background Technology

[0002] A gyratory mixer is a mechanical device that improves mixing efficiency through compound motion. It is commonly used in concrete mixing, chemical and food processing. To enhance the performance of the gyratory mixer, a boom mechanism is installed to move the gyratory mixer, thus increasing its stroke.

[0003] The existing oscillating mixing structure lacks a mechanism to increase the stroke, which means that the stroke of the oscillating mixing cannot be adjusted, thus failing to improve the flexibility and mixing effect of the oscillating mixing.

[0004] In view of this, it is necessary to develop a crank arm mechanism to improve the swing stroke of the stirring structure, thereby effectively increasing the swing stroke of the stirring structure. Utility Model Content

[0005] The purpose of this utility model is to provide a crank arm mechanism that improves the swinging stroke, so as to solve the technical problem mentioned in the background art that the swinging stirring structure lacks a mechanism to improve the stroke, resulting in the swinging stirring stroke being unable to be adjusted, and thus the flexibility and stirring effect of the swinging stirring cannot be improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crank arm mechanism for improving the stirring and oscillating stroke, comprising: a mounting cylinder, wherein a screw drive assembly is installed inside the mounting cylinder, the screw drive assembly includes a drive screw, a screw sleeve, a connecting block, and an arc plate, the drive screw is rotatably installed inside the mounting cylinder, the screw sleeve is fitted around the outside of the drive screw, the connecting blocks are symmetrically installed on both sides of the screw sleeve and extend through both sides of the mounting cylinder, and the arc plate is installed on the outside of the connecting blocks.

[0007] Preferably, the mounting cylinder has symmetrical grooves on both sides, and the grooves are slidably connected to the connecting block.

[0008] Preferably, a mounting rod is installed at the bottom of the arc-shaped plate.

[0009] Preferably, the top of the mounting cylinder is provided with a through groove, the top of the through groove is provided with a sealing cover, and the top of the mounting cylinder is provided with a mounting bracket.

[0010] Preferably, a drive motor is bolted to the front of the mounting cylinder, and the output end of the drive motor is connected to the transmission screw. A sealing cylinder is installed on the outside of the mounting cylinder, and the sealing cylinder is located outside the drive motor.

[0011] Preferably, the top of the lead screw sleeve has a through opening, an oil storage box is installed on the top of the lead screw sleeve, and a locking cover is installed on the top of the oil storage box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by driving the internal transmission screw to rotate, since the transmission screw and the screw sleeve are threadedly engaged and the screw sleeve is limited by the connecting block passing through the slide groove, the screw sleeve can move outward by the rotation of the transmission screw. The slide groove provides space for the connecting block to pass through the mounting cylinder. The arc plate connects the connecting block and provides an installation position for the mounting rod. The mounting rod is used to install the swing stirring structure, so that the screw transmission assembly drives the swing stirring structure to move, thereby increasing the stirring stroke.

[0014] 2. In this utility model, the movement of the lead screw sleeve allows it to move below the through groove, enabling the locking cover on the oil reservoir at the top of the lead screw sleeve to be removed. After the locking cover is removed, the opening at the top of the oil reservoir is opened, allowing the operator to add lubricating oil into the oil reservoir through the through groove. The added lubricating oil will slowly flow out through the through opening to the inside of the lead screw sleeve, thereby lubricating the lead screw sleeve and the transmission lead screw, making lubrication more convenient. At the same time, because the lead screw sleeve moves outside the transmission lead screw, the lubrication uniformity is higher and the lubrication effect is better. Attached Figure Description

[0023] Please see Figures 1-4 A crank arm mechanism for improving the stirring and oscillating stroke;

[0024] The device includes: a mounting cylinder 1, inside which a screw drive assembly is installed. The screw drive assembly includes a drive screw 8, a screw sleeve 9, a connecting block 10, and an arc plate 11. The drive screw 8 is rotatably installed inside the mounting cylinder 1. The screw sleeve 9 is fitted around the outside of the drive screw 8. The connecting block 10 is symmetrically installed on both sides of the screw sleeve 9 and passes through both sides of the mounting cylinder 1. The arc plate 11 is installed on the outside of the connecting block 10. The mounting cylinder 1 has symmetrically opened sliding grooves 7 on both sides, and the sliding grooves 7 are slidably connected to the connecting block 10. An mounting rod 12 is installed at the bottom of the arc plate 11.

[0025] The mounting cylinder 1 provides an installation position for the screw drive assembly, which is used to drive the oscillating mixing assembly to move, thereby increasing the stroke of the oscillating mixing assembly. When in use, the screw drive assembly is powered by the drive motor 2, which drives the internal transmission screw 8 to rotate. Since the transmission screw 8 is threadedly engaged with the screw sleeve 9, and the screw sleeve 9 is limited by the connecting block 10 passing through the slide groove 7, the screw sleeve 9 can move outward through the rotation of the transmission screw 8. The slide groove 7 provides space for the connecting block 10 to pass through the mounting cylinder 1. The arc plate 11 connects the connecting block 10 and provides an installation position for the mounting rod 12. The mounting rod 12 is used to install the oscillating mixing structure, thereby enabling the screw drive assembly to drive the oscillating mixing structure to move, thus increasing the mixing stroke.

[0026] Please see Figure 1 , Figure 2 and Figure 4 A crank arm mechanism for improving the stirring and oscillating stroke;

[0027] The top of the mounting cylinder 1 is provided with a through groove 4, and a sealing cover 5 is installed on the top of the through groove 4. The top of the mounting cylinder 1 is provided with a mounting bracket 6. The front of the mounting cylinder 1 is provided with a drive motor 2 by bolts, and the output end of the drive motor 2 is connected to the transmission screw 8. A sealing cylinder 3 is installed on the outside of the mounting cylinder 1, and the sealing cylinder 3 is located outside the drive motor 2. The top of the screw sleeve 9 is provided with a through opening 15, and an oil storage box 13 is installed on the top of the screw sleeve 9. A locking cover 14 is installed on the top of the oil storage box 13.

[0028] The drive motor 2 is a reversible motor that converts electrical energy into kinetic energy after being powered on. The sealing cylinder 3 is used to protect the drive motor 2. By removing the sealing cover 5, the top through slot 4 is opened. After the through slot 4 is opened, the lead screw sleeve 9 moves to the bottom of the through slot 4, so that the locking cover 14 on the oil storage box 13 at the top of the lead screw sleeve 9 can be removed. After the locking cover 14 is removed, the opening at the top of the oil storage box 13 is opened, so that the operator can add lubricating oil to the inside of the oil storage box 13 through the through slot 4. The added lubricating oil will slowly flow out through the through port 15 to the inside of the lead screw sleeve 9, thereby lubricating the lead screw sleeve 9 and the transmission lead screw 8, making lubrication more convenient. At the same time, since the lead screw sleeve 9 moves outside the transmission lead screw 8, the lubrication uniformity is higher and the lubrication effect is better. The mounting bracket 6 provides a position for the installation of the articulated boom mechanism.

[0029] Working principle: First, the articulated arm structure is installed in the desired position using the mounting bracket 6. The oscillating stirring structure is connected to the mounting rod 12. The drive motor 2 is turned on by the controller, and the drive motor 2 provides power to the transmission screw 8, thereby causing the transmission screw 8 to rotate. The rotation of the transmission screw 8 causes the screw sleeve 9 to move. Since the screw sleeve 9 is connected to the mounting rod 12 through the connecting block 10 and the arc plate 11, it drives the oscillating stirring structure to move, thereby increasing the oscillating stroke of the oscillating stirring structure. If it is necessary to add lubricating oil to the inside, the lubricating oil can be added to the oil storage box 13 by opening the sealing cover 5 and the locking cover 14, which is convenient for adding lubricating oil to the articulated arm mechanism.
