Description

Technical Field

[0001] This utility model belongs to the field of feeder technology, specifically relating to a feeder with a limiting structure. Background Technology

[0002] A feeder is a mechanical device used to continuously and evenly transport bulk materials from storage bins or other storage equipment to subsequent production equipment (such as crushers, conveyor belts, screening machines, etc.). It is widely used in industries such as mining, metallurgy, building materials, chemicals, coal, and power.

[0003] A vibratory motor feeder is a mechanical device that uses a vibratory motor as the excitation source to uniformly, continuously, or quantitatively transport materials from a storage silo or other storage equipment to a receiving device through vibration. The working principle of a vibratory motor feeder is based on vibration dynamics and inertial forces. The vibratory motor contains a set of eccentric blocks. When the motor rotates, the eccentric blocks generate centrifugal force. Due to the asymmetrical distribution of the eccentric blocks, the centrifugal force changes periodically in both the horizontal and vertical directions, thus forming a vibrational force. This vibrational force is transmitted to the feeding trough through a spring support device, causing the trough to vibrate periodically. Driven by the vibrational force, the material in the trough moves forward along the trough, achieving continuous and uniform feeding.

[0004] Existing traditional vibratory motor feeders have significant limitations in their structural design, particularly the lack of a scientifically effective limiting structure, which makes it impossible to control the feeding process. Specifically, these devices mainly rely on the continuous operation of the vibratory motor to move the material along the trough. However, because there is no upper limit constraint mechanism for the material conveying capacity, the actual feeding amount depends entirely on the output of the upstream feeding equipment. When the feeder continuously delivers material to the feeder at a large flow rate, the vibratory motor can only intervene to a limited extent in the material conveying speed by adjusting its own vibration frequency and amplitude, but it cannot fundamentally limit the accumulation of material. In this situation, once the feeding amount exceeds the immediate processing capacity of the downstream process, it is very easy for the material to accumulate excessively in the feeder trough or subsequent conveying channels, leading to a chain of failures such as material overflow, equipment overload, and conveying jams. Utility Model Content

[0005] The purpose of this utility model is to provide a feeder with a limiting structure, which aims to solve the problem that in the prior art, the feeder mainly relies on the continuous operation of the vibrating motor to push the material along the trough. However, because there is no upper limit constraint mechanism for the material conveying capacity, the actual feeding capacity depends entirely on the output of the upstream feeding equipment. When the feeder continuously conveys material to the feeder at a large flow rate, the vibrating motor can only intervene in the material conveying speed to a limited extent through the adjustment of its own vibration frequency and amplitude, but cannot fundamentally limit the accumulation of material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeder with a limiting structure, comprising a feeder base, a feeder housing, and a vibrating motor. The feeder housing is mounted on the top of the feeder base, and the vibrating motor is mounted on the bottom side of the feeder housing. A bracket is connected to the surface of the feeder housing, and a telescopic rod is mounted on the surface of the bracket. A connecting lug is connected to the telescopic end of the telescopic rod, and a limiting plate is connected to the side surface of the connecting lug. A limiting strip is connected to the inner wall of the feeder housing.

[0007] As a preferred embodiment of the feeder with a limiting structure of this utility model, the telescopic rod forms a telescopic structure with the limiting plate through the connecting lug.

[0008] As a preferred embodiment of the feeder with a limiting structure of this utility model, the limiting strips are symmetrically arranged on both sides of the limiting plate, and the limiting plate and the limiting strips form a sliding connection.

[0009] As a preferred embodiment of the feeder with a limiting structure of this utility model, a guide baffle is connected to the bottom side of the inner wall of the feeder housing, a guide block runs through the inside of the feeder housing, a guide hole is opened on the inner wall of the guide block, a connecting block is connected to the surface of the guide block, a guide rod is connected to the inner wall of the feeder housing through the connecting block, a threaded tube runs through the inside of the connecting block, a threaded rod runs through the inside of the threaded tube, the threaded rod is mounted on the surface of the feeder housing through a bearing seat, and the other end of the threaded rod is connected to the output end of the drive motor, the drive motor is mounted on the side surface of the feeder housing.

[0010] In a preferred embodiment of the feeder with a limiting structure of this utility model, the guide block and the feeder housing are slidably connected.

[0011] In a preferred embodiment of the feeder with a limiting structure according to this utility model, the connecting block and the guide rod are slidably connected.

[0012] In a preferred embodiment of the feeder with a limiting structure of this utility model, the threaded rod and the threaded tube are connected by a thread, and the threaded rod forms a rotating structure with the feeder housing through a bearing seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the telescopic rod can drive the connecting ear downwards during operation. When the connecting ear moves downwards, it can drive the limiting plate to slide downwards on the inner wall of the limiting strip. This can control the height of the limiting plate, thereby limiting the amount of material fed when the output of the upstream feeding equipment is large. This can limit the amount of material fed by the feeder, preventing the amount of material from exceeding the immediate processing capacity of the downstream process and causing excessive accumulation of material in the feeder trough or subsequent conveying channel.

[0015] In this invention, the drive motor can rotate the threaded rod when it runs. When the threaded rod rotates, it drives the connecting block to move laterally through the threaded tube. When the connecting block moves laterally, it can drive the guide block to move laterally. When the guide block moves laterally, it can drive the guide hole to move laterally. This allows the lateral position of the guide hole to be adjusted, so that the material can enter the discharge port formed by different guide partitions through the guide hole. Thus, the discharge position can be controlled according to the actual needs of the downstream process equipment. Attached Figure Description

[0028] Preferably, the limiting strips 8 are symmetrically arranged on both sides of the limiting plate 7, and the limiting plate 7 and the limiting strips 8 form a sliding connection.

[0029] In practical use, when the limiting plate 7 is subjected to force, it can slide on the inner wall of the limiting strip 8, which can limit the movement direction of the limiting plate 7.
