Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a material feeding and conveying device. Background Art

[0002] The feeding and conveying device is an auxiliary equipment in the mechanized storage and transportation system of a production enterprise. Its main function is to continuously and evenly feed processed or unprocessed materials from a certain equipment (hopper, storage bin, etc.) to the receiving equipment or transportation machinery.

[0003] The existing material feeding and conveying device will have its drop point impacted by the upstream belt material for a long time. Although buffer rollers are provided at the drop point to greatly reduce the impact of the material when it falls, it cannot avoid damage to the conveyor belt surface. Long-term use will still increase the wear of the conveyor belt and shorten its service life. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the above background and to propose a material feeding and conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material feeding and conveying device, comprising a base plate, four vertical plates fixedly mounted on the surface of the base plate, a conveyor belt disposed between the four vertical plates, two support rods fixedly mounted on the surface of the base plate, a lower hopper fixedly mounted on one end of the two support rods away from the base plate, a buffer device disposed on the surface of the base plate, the buffer device comprising vertical rods fixedly mounted on the surface of the base plate, a slide plate slidably connected to the surface of the vertical rod, a load-bearing bucket fixedly mounted on the side of the slide plate. The arrangement of the slide plate and the vertical rods allows the load-bearing bucket to move stably.

[0006] Preferably, two L-shaped plates are fixedly mounted on the surface of the bottom plate, a slide bar is fixedly mounted between the two L-shaped plates, two movable plates are slidably connected to the surface of the slide bar, and a spring is fixedly mounted between the two movable plates. The provision of the spring serves to limit the position of the movable plate on the surface of the slide bar.

[0007] Preferably, a hinged plate is hingedly connected to the top surface of the movable plate, a horizontal strip is fixedly mounted on the surface of the end of the carrying bucket away from the slide plate, and the end of the hinged plate away from the movable plate is hingedly connected to the horizontal strip. The arrangement of the hinged plate has the effect of driving the movable plate to move on the surface of the slide rod.

[0008] Preferably, a limiting device is provided on the surface of the base plate, comprising a U-shaped bracket fixedly mounted on the surface of the base plate, with two support plates fixedly mounted on the top surface of the U-shaped bracket, a threaded rod rotatably connected between the two support plates, a rotating wheel fixedly mounted on the surface of the threaded rod, and threads on the surface of the threaded rod being mutually oppositely threaded with the rotating wheel as the center. The provision of the rotating wheel serves to drive the threaded rod to rotate.

[0009] Preferably, a through slot is formed on the top surface of the U-shaped bracket, a cross bar is fixedly installed between the inner walls of both ends of the through slot, and two movable plates are threadedly connected to the surface of the threaded rod. The arrangement of the threaded rod drives the movable plates to move on the surface of the cross bar.

[0010] Preferably, a round rod is fixedly mounted on the bottom surface of the movable plate, and a limit plate is fixedly mounted on one end of the round rod away from the movable plate. The setting of the limit plate has the effect of limiting the material on the surface of the conveyor belt.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] When the material is fed into the loading bucket, the loading bucket is forced downward, and the loading bucket moves downward, driving the slide plate to move downward on the surface of the vertical rod. At the same time, the movement of the loading bucket also drives the cross plate to move downward, and the cross plate drives the hinged plate to move downward, and the movement of the hinged plate will push the two moving plates to move away from each other on the surface of the slide rod, and the two moving plates will drive the spring to stretch. At this time, the rebound force of the spring plays a certain buffering role, so that the impact force of the material falling on the loading bucket is buffered, so that the material can roll onto the surface of the conveyor belt under the guidance of the loading bucket. Through the cooperation of the above structure, it is avoided that large pieces of material directly fall onto the surface of the conveyor belt, causing serious wear on its belt surface for a long time, thereby extending the service life of the conveyor belt.

[0013] 2. In the present invention, a limit device is provided, and when it is necessary to limit the material on the surface of the conveyor belt, the wheel is first rotated, and the rotation of the wheel drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are in opposite directions with the wheel as the center, when the wheel drives the threaded rod to rotate, the two movable plates threadedly connected on its surface will move in the direction of approaching each other on the surface of the cross bar, and the two movable plates move in the direction of approaching each other on the surface of the cross bar, driving the two round rods to move in the opposite direction of approaching each other. The movement of the two round rods in the direction of approaching each other drives the two limit plates to move in the direction of approaching each other. When the two limit plates move to the appropriate position, the rotation of the wheel can be stopped. Through the cooperation of the above structure, the limit plates can limit the material on the surface of the conveyor belt, thereby preventing the material from slipping from the surface of the conveyor belt, which will have an adverse effect on the transportation of the material.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] See also Figure 1-5 The utility model provides a technical solution: a material feeding and conveying device, including a base plate 1, four vertical plates 2 are fixedly installed on the surface of the base plate 1, a conveyor belt 3 is provided between the four vertical plates 2, two support rods 6 are fixedly installed on the surface of the base plate 1, and a lower hopper 7 is fixedly installed at one end of the two support rods 6 away from the base plate 1.

[0024] The specific configuration and function of the buffer device 4 and the limit device 5 will be described in detail below.

[0025] In this embodiment: a buffer device 4 is provided on the surface of the base plate 1, and the buffer device 4 includes a vertical rod 41, which is fixedly installed on the surface of the base plate 1, and a slide plate 42 is slidably connected to the surface of the vertical rod 41, and a load bucket 43 is fixedly installed on the side of the slide plate 42.

[0026] In this embodiment, the arrangement of the slide plate 42 and the vertical pole 41 enables the carrying bucket 43 to move stably.

[0027] Specifically, two L-shaped plates 45 are fixedly installed on the surface of the bottom plate 1, a slide rod 46 is fixedly installed between the two L-shaped plates 45, and two movable plates 47 are slidably connected to the surface of the slide rod 46, and a spring 48 is fixedly installed between the two movable plates 47.

[0028] In this embodiment, the setting of the spring 48 has the effect of limiting the position of the movable plate 47 on the surface of the slide rod 46.

[0029] Specifically, a hinge plate 49 is hingedly connected to the top surface of the movable plate 47, a horizontal strip 44 is fixedly mounted on the surface of the end of the carrying bucket 43 away from the slide plate 42, and the end of the hinge plate 49 away from the movable plate 47 is hingedly connected to the horizontal strip 44. The provision of the hinge plate 49 has the effect of driving the movable plate 47 to move on the surface of the slide bar 46.

[0030] In this embodiment: a limiting device 5 is provided on the surface of the base plate 1, and the limiting device 5 includes a U-shaped bracket 51, which is fixedly installed on the surface of the base plate 1, and two support plates 52 are fixedly installed on the top surface of the U-shaped bracket 51. A threaded rod 53 is rotatably connected between the two support plates 52, and a rotating wheel 54 is fixedly installed on the surface of the threaded rod 53. The threads on the surface of the threaded rod 53 are reverse threads with the rotating wheel 54 as the center. When it is necessary to limit the material on the surface of the conveyor belt 3, first rotate the wheel 54. The rotation of the wheel 54 drives the threaded rod 53 to rotate. Since the threads on the surface of the threaded rod 53 are opposite threads with the wheel 54 as the center, when the wheel 54 drives the threaded rod 53 to rotate, the two movable plates 57 threadedly connected on its surface will move toward each other on the surface of the cross bar 56. The two movable plates 57 move in the direction of approaching each other on the surface of the cross bar 56, driving the two round rods 58 to move in the opposite direction of approaching each other. The two round rods 58 move in the direction of approaching each other, driving the two limiting plates 59 to move in the direction of approaching each other. When the two limiting plates 59 move to the appropriate position, stop rotating the wheel 54. Through the cooperation of the above structure, the limiting plates 59 can limit the material on the surface of the conveyor belt 3, thereby preventing the material from slipping from the surface of the conveyor belt 3 and adversely affecting the conveyor belt 3 of the material.

[0031] Specifically, a through slot 55 is formed on the top surface of the U-shaped bracket 51 , a cross bar 56 is fixedly installed between the inner walls at both ends of the through slot 55 , and two movable plates 57 are threadedly connected to the surface of the threaded rod 53 .

[0032] In this embodiment, the threaded rod 53 is provided to drive the movable plate 57 to move on the surface of the cross bar 56 .

[0033] Specifically, a round rod 58 is fixedly mounted on the bottom surface of the movable plate 57 , and a limiting plate 59 is fixedly mounted on one end of the round rod 58 away from the movable plate 57 .

[0034] In this embodiment, the setting of the limiting plate 59 has the effect of limiting the material on the surface of the conveyor belt 3.

[0035] Working principle: By setting the buffer device 4, when the device needs to be used, first place the entire device in a suitable position, then make the material fall into the interior of the lower hopper 7, and the material will enter the interior of the carrying bucket 43 from the interior of the lower hopper 7. When the material enters the interior of the carrying bucket 43, the carrying bucket 43 will be forced to move downward, and the downward movement of the carrying bucket 43 drives the slide plate 42 to move downward on the surface of the vertical rod 41. At the same time, the movement of the carrying bucket 43 also drives the horizontal plate to move downward, and the downward movement of the horizontal plate drives the hinged plate 49 to move, and the movement of the hinged plate 49 will push the two moving plates 47 When the surface of the slide bar 46 moves away from each other, the two movable plates 47 move away from each other on the surface of the slide bar 46, which will drive the spring 48 to stretch. At this time, the rebound force of the spring 48 plays a certain buffering role, so that the impact force of the material falling on the carrying bucket 43 is buffered, so that the material can roll onto the surface of the conveyor belt 3 under the guidance of the carrying bucket 43. Through the cooperation of the above structure, large pieces of material are prevented from falling directly onto the surface of the conveyor belt 3, causing serious wear on its belt surface for a long time, so that the service life of the belt surface of the conveyor belt 3 is extended. When it is necessary to limit the material on the surface of the conveyor belt 3, first rotate the wheel 54. The rotation of the wheel 54 drives the threaded rod 53 to rotate. Since the threads on the surface of the threaded rod 53 are opposite threads with the wheel 54 as the center, when the wheel 54 drives the threaded rod 53 to rotate, the two movable plates 57 threadedly connected on its surface will move toward each other on the surface of the cross bar 56. The two movable plates 57 move in the direction of approaching each other on the surface of the cross bar 56, driving the two round rods 58 to move in the opposite direction of approaching each other. The two round rods 58 move in the direction of approaching each other, driving the two limiting plates 59 to move in the direction of approaching each other. When the two limiting plates 59 move to the appropriate position, stop rotating the wheel 54. Through the cooperation of the above structure, the limiting plates 59 can limit the material on the surface of the conveyor belt 3, thereby preventing the material from slipping from the surface of the conveyor belt 3 and adversely affecting the conveyor belt 3 of the material.
