Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, in particular to a vibrating feeder exciter and an angle adjustment method. Background Art

[0002] A vibrator is a device that generates excitation force and transmits it to the equipment it's mounted on, causing it to vibrate according to the designed trajectory. As the excitation component of a vibrating feeder, the vibrator causes the feeder to vibrate linearly at a specific angle and amplitude, enabling tasks such as material conveying and screening. Vibrating feeders are used in crushing and screening equipment to transport material to various crushers. The material flow varies depending on the crushing process, raw material type, and operating environment.

[0003] Material particle size, composition, humidity, and viscosity all influence the efficiency of a vibrating feeder, which is primarily determined by amplitude, frequency, and vibration angle. When handling different materials, vibrating feeders have corresponding optimal amplitude, frequency, and vibration angle. This requires vibrating feeders to be able to quickly and easily adjust amplitude, frequency, and vibration angle, allowing a single machine to adapt to a variety of operating conditions. The amplitude and vibration angle are determined by the vibrating feeder's exciter, which is the power source that enables the vibrating feeder to transport materials.

[0004] At present, the eccentric shaft vibrator is a commonly used excitation source for vibrating feeders. The eccentric shaft vibrator generates an excitation force by rotating two eccentric shafts relative to each other at an initial installation angle. The vibration direction angle of the vibrating feeder is determined by the initial installation angle of the two eccentric shafts, and the initial installation angle of the two eccentric shafts is determined by the meshing position of a set of meshing gears. When the vibration direction angle needs to be changed, the existing technical solution requires removing the driven gear, manually rotating the eccentric shaft, and reinstalling the gear at the required angle. The process is complicated, difficult to adjust, time-consuming and labor-intensive. Moreover, during the manual rotation process, the eccentric shaft rotates due to gravity, which can easily cause the operator's fingers to be squeezed and injured, posing a safety hazard. Therefore, the existing technical solution cannot meet the demand for rapid adjustment of the vibration direction angle of the vibrating feeder under different working conditions.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] like Figures 1 to 7 The vibrating feeder exciter shown in the figure includes a drum frame 5, in which a driving eccentric shaft 1 and a driven eccentric shaft 2 are provided in parallel. One end of the driving eccentric shaft 1 is connected to a driving gear 3, and one end of the driven eccentric shaft 2 is connected to a driven gear assembly 4. The driving gear 3 is meshed with the driven gear assembly 4. The other end of the driving eccentric shaft 1 is connected to a driving device 6 via a coupling 7.

[0049] S3, connecting the angle adjustment tool 13 and the inner gear ring 42;

[0054] In the description provided herein, numerous specific details are described. However, it is understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

[0055] The present invention relates to a vibrating feeder and an angle adjustment method. The vibrating feeder is installed at the bottom of the vibrating feeder. When the device is in operation, the driving device drives the driving eccentric shaft through a coupling. Through the mutually meshing driving gear and driven gear assembly, the driving eccentric shaft drives the driven eccentric shaft to rotate. The two eccentric shafts rotate in opposite directions. The centrifugal force of the two eccentric shafts is combined into an exciting force with a constant magnitude in a certain direction. This exciting force drives the vibrating feeder to move in a certain direction, forming a linear vibration trajectory. The angle between the above direction and the horizontal plane is the vibration direction angle. This angle is determined by the initial relative installation angle of the two eccentric shafts. The initial relative installation angle is determined by the outer gear ring angle adjustment hole selected when assembling the driven gear assembly. This angle is usually between 30° and 60°, and the specific value is selected according to actual use requirements. The present invention solves the problem that the existing eccentric shaft type vibrator needs to disassemble the gear to change the vibration direction angle, which is difficult to operate, reduces working time, and realizes rapid adjustment of the vibration direction angle of the vibrating feeder. At the same time, the vibration direction is changed in conjunction with a special tool for angle adjustment, which reduces workload and ensures the safety of operators.

[0057] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention.
