Description

Technical Field

[0001] The utility model belongs to the technical field of conveyors, and in particular relates to a buffering and shock-absorbing conveyor. Background Art

[0002] A belt conveyor is a machine that continuously transports materials using friction drive. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. A belt conveyor is a transportation system for transporting cargo raw materials over long distances, in large quantities, and at high speeds, and is widely used in the coal industry.

[0003] At present, most of the existing conveyors lack buffering and shock-absorbing structures. During the operation of the conveyor, goods are usually placed directly onto the conveyor. When the conveyor is used to transport heavy objects, the heavy objects falling directly onto the conveyor will cause a huge impact. The conveyor is easily damaged by long-term impact, shortening its service life. Utility Model Content

[0004] The purpose of the present utility model is to provide a buffering and shock-absorbing conveyor to solve the problems raised in the above background technology.

[0005] The cam is connected with the support frame to form a circle, and the cam is connected with the support frame to form a circle.

[0006] As a preferred embodiment, a conveyor belt is rotatably mounted on the conveyor frame, and a motor for driving the conveyor belt to rotate is fixedly mounted on one side of the conveyor frame.

[0007] As a preferred embodiment, the first spring is sleeved on the fixing rod.

[0008] As a preferred embodiment, the guide groove is arranged obliquely.

[0009] As a preferred embodiment, limiting grooves are provided at the four corners of the top of the base, and limiting rods are fixedly connected to the four corners of the bottom of the conveying frame, and the lower ends of the limiting rods slide and extend into the limiting grooves.

[0010] As a preferred embodiment, a third spring is provided in the limiting groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The buffering and shock-absorbing conveyor has a buffering assembly. When a heavy object falls onto the conveyor belt, the conveyor frame is pressed downward by the force, causing the support seat to slide downward in the base. The support seat squeezes the support rod, causing the support rod to drive the slider to slide along the fixed rod, causing the slider to squeeze the first spring. The first spring is used to buffer the instantaneous impact force on the conveyor belt, thereby reducing the instantaneous impact caused by the conveyor.

[0013] This buffered shock-absorbing conveyor, through the setting of the shock-absorbing component, when the support seat slides downward in the base, the hydraulic damper can absorb and reduce the impact force, and at the same time drive the guide block to slide in the guide groove, so that the guide block drives the movable rod to slide toward the fixed seat, so that the movable rod squeezes the second spring, thereby achieving the shock-absorbing effect and extending the service life of the conveyor.

[0020] See also Figure 1-3 The utility model provides a buffered shock-absorbing conveyor, including a base 1, a support base 2, a conveying frame 3, a buffer assembly 4 and a shock-absorbing assembly 5. The support base 2 is slidably installed on the base 1, and the conveying frame 3 is fixedly installed on the support base 2. A conveyor belt 31 is rotatably installed on the conveying frame 3, and a motor 32 for driving the conveyor belt 31 to rotate is fixedly installed on one side of the conveying frame 3.

[0021] The buffer assembly 4 includes a fixed rod 41, a slider 42, a first spring 43 and a support rod 44. The fixed rod 41 is fixedly mounted on the inner bottom wall of the base 1, the slider 42 is slidably sleeved on the fixed rod 41, the first spring 43 is sleeved on the fixed rod 41, the first spring 43 is abutted on one side of the slider 42, and the support rod 44 is hinged between the slider 42 and the support seat 2. Through the setting of the buffer assembly 4, when a heavy object falls on the conveyor belt 31, the conveyor frame 3 will be pressed down by the force, causing the support seat 2 to slide downward in the base 1, and the support seat 2 will squeeze the support rod 44, so that the support rod 44 drives the slider 42 to slide along the fixed rod 41, so that the slider 42 squeezes the first spring 43, and the first spring 43 is used to buffer the instantaneous impact force on the conveyor belt 31, thereby reducing the instantaneous impact caused by the conveyor.

[0022] The shock absorbing assembly 5 includes a fixed seat 51, a hydraulic damper 52, a movable rod 53 and a second spring 54. The fixed seat 51 is fixedly connected to the inner bottom wall of the base 1, and the hydraulic damper 52 is embedded in the fixed seat 51. The upper end of the hydraulic damper 52 is fixedly connected to the inner top wall of the support seat 2. Grooves 55 are provided on both sides of the fixed seat 51. The inner wall of the groove 55 is provided with a guide groove 56. The guide groove 56 is arranged obliquely. A guide block 57 is slidably connected to the inside of the guide groove 56.
