Description

Technical Field

[0001] This utility model relates to the technical field of building material conveying machinery, and in particular to the technical field of a buffer hopper suitable for large particle materials. Background Technology

[0002] The bucket is an important part of the elevator for loading materials. Its main function is to transport materials from the feed inlet to the discharge outlet of the elevator. The design of the elevator bucket should take into account factors such as the properties of the material, the conveying capacity, and the conveying height to ensure the normal operation of the elevator and the high efficiency of material conveying.

[0003] In industries such as chemical, metallurgy, and building materials, the conveying and storage of large particulate materials (such as ores, coal blocks, and plastic granules) often leads to equipment wear, increased energy consumption, and higher maintenance costs due to material impact, accumulation, and blockage. Traditional rigid hoppers are prone to deformation due to material impact and cannot adapt to the flow requirements of materials with different particle sizes. Therefore, this application proposes a buffer hopper suitable for large particulate materials. Through flexible structural design, it effectively alleviates impact, reduces blockage, and improves material flow efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a buffer hopper suitable for large particle materials, which can effectively alleviate impact, reduce blockage, and improve material flow efficiency.

[0005] To achieve the above objectives, this utility model proposes a buffer hopper suitable for large particulate materials, comprising a hopper body, a buffer mechanism provided on the inner side of the lower sidewall of the hopper body, the buffer mechanism comprising an elastic mechanism and a buffer plate disposed on the elastic mechanism, the front and rear ends of the buffer plate being bent downward to form two outer baffles, and two inner baffles provided on the inner side of the lower sidewall of the hopper body respectively located inside the two outer baffles, the inner baffles and the outer baffles cooperating to form a labyrinth sealing structure.

[0006] Preferably, the elastic mechanism includes a base, a mounting base, and a plurality of elastic elements disposed between the base and the mounting base.

[0007] Preferably, the elastic element includes two supports, several springs, a support plate, a nut, and a support head. Each support is slidably provided with a sliding rod. The spring is located between the two supports. The upper end of the spring is provided with a support plate. The support plate is provided with a nut. The nut is provided with a support head that is threadedly engaged with it.

[0008] Preferably, the lower side wall of the hopper body is provided with a number of ventilation holes located between the base and the inner sidewall at the rear.

[0009] Preferably, the front end of the lower side wall of the hopper body is provided with an upwardly inclined feeding plate, and the feeding plate is welded and fixedly connected to the left and right side walls of the hopper body.

[0010] Preferably, the lower end of the feed plate is provided with a transition portion flush with the buffer plate.

[0011] Preferably, both the left and right side walls of the hopper body extend downward to form a material-blocking flange.

[0012] Preferably, the bottom of the hopper body is V-shaped, and a buffer mechanism is also provided on the lower side of the bottom of the hopper body.

[0013] The beneficial effects of this utility model are as follows: By providing a buffer mechanism on the inner side of the lower side wall of the hopper body, the buffer mechanism includes an elastic mechanism and a buffer plate disposed on the elastic mechanism. When large particles of material fall, the impact force on the buffer plate is absorbed by the elastic mechanism, thereby slowing down the falling speed of the material and reducing the impact on the hopper. During the compression and rebound process of the elastic mechanism, the elastic effect causes the hopper wall to generate slight vibrations. This vibration helps to prevent material from adhering to and clogging the inner wall of the hopper, and promotes the smooth sliding of the material. Compared with the prior art, it can effectively alleviate the impact, reduce clogging, and improve the material flow efficiency.

[0014] The front and rear ends of the buffer plate are bent downward to form two outer baffles. The inner side of the lower side wall of the hopper body is provided with two inner baffles located inside the two outer baffles respectively. The inner baffles and the outer baffles cooperate to form a labyrinth seal structure, which can prevent materials from entering the buffer mechanism and ensure the stability and reliability of the equipment operation.

[0015] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model discloses a buffer hopper suitable for large particle materials, including a hopper body 1. A buffer mechanism 2 is provided on the inner side of the lower side wall of the hopper body 1. The buffer mechanism 2 includes an elastic mechanism 21 and a buffer plate 22 provided on the elastic mechanism 21. The front and rear ends of the buffer plate 22 are bent downward to form two outer baffles 23. Two inner baffles 24 are provided on the inner side of the lower side wall of the hopper body 1, respectively located inside the two outer baffles 23. The inner baffles 24 and the outer baffles 23 cooperate to form a labyrinth sealing structure.

[0019] The elastic mechanism 21 includes a base 211, a mounting base 212, and a plurality of elastic elements 213 disposed between the base 211 and the mounting base 212.

[0020] The elastic element 213 includes two supports 2131, several springs 2132, a support plate 2133, a nut 2134, and a support head 2135. Each support 2131 is slidably provided with a sliding rod 2136. The springs 2132 are located between the two supports 2131. The upper end of the springs 2132 is provided with a support plate 2133. The support plate 2133 is provided with a nut 2134. The nut 2134 is provided with a support head 2135 that is threadedly engaged with it.

[0021] The lower side wall of the hopper body 1 is provided with several ventilation holes 3 located between the base 211 and the inner edge 24 behind it.

[0022] The front end of the lower side wall of the hopper body 1 is provided with an upwardly inclined feeding plate 4, which is welded and fixedly connected to the left and right side walls of the hopper body 1.

[0023] The feed plate 4 has a transition section 6 at its lower end that is flush with the buffer plate 22.

[0024] The left and right side walls of the hopper body 1 both extend downward to form material-blocking flanges 5.

[0025] The bottom of the hopper body 1 is V-shaped, and a buffer mechanism 2 is also provided on the lower side of the bottom of the hopper body 1.

[0026] The working process of this utility model: This utility model discloses a buffer hopper suitable for large particle materials. During operation, the material falls into the hopper through the feed inlet of the elevator. The impact force generated by the falling material acts on the buffer plate 22. The buffer plate 22, through the cooperation of the support head 2135, nut 2134 and support plate 2133, acts on the spring 2132. The spring 2132 is compressed and deformed, converting the kinetic energy of the material into the elastic potential energy of the spring 2132, thereby slowing down the falling speed of the material, reducing the impact on the hopper, reducing the wear and deformation of the hopper, and extending the service life of the hopper.

[0027] During the compression and rebound of spring 2132, the elasticity of spring 2132 causes the hopper wall to vibrate slightly, preventing excessive accumulation of material in a certain area. At the same time, this vibration helps prevent material from adhering to and clogging the inner wall of the hopper, and promotes the smooth sliding of material.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
