Description

Technical Field

[0001] The utility model relates to a material flow quick regulating device for solid bulk fluid, belonging to the fields of production, detection, transportation and the like of bulk mineral materials. Background Art

[0002] In the production, testing, and transportation of bulk minerals, the material flow height during material transportation is usually controlled only by the distance between the inlet hopper and the edge of the belt conveyor's outer cover. This will cause the material flow height to fluctuate in a wavy manner. This non-uniform feeding method often causes material to scatter or cause production equipment such as back-end crushing and reduction to "block" due to other reasons.

[0003] In order to prevent the material flow from spilling during transportation or causing the production equipment to "block" the machine, a material flow quick adjustment device that can be used for solid bulk fluids has become a goal pursued by those skilled in the art.

[0004] The purpose of the utility model is to solve the problems in the existing technical fields of production, detection and transportation of bulk minerals, such as the easy scattering of materials during transportation or the "stuck machine" of production equipment, so as to achieve the purpose of uniform feeding.

[0005] This utility model aims to provide a quick flow adjustment device for solid bulk fluids. Installed at the inlet hopper end of a belt conveyor, it can freely limit the height of the material flow according to the height of the incoming material, achieving the purpose of uniform and stable material transportation and preventing the occurrence of material blockage or machine jams in the production equipment such as sample preparation and crushing at the rear end, thereby ensuring the smooth and efficient completion of the material production flow process.

[0006] The technical solution of the present utility model is: a material flow quick adjustment device for solid bulk fluid, characterized in that it includes: a door-shaped support frame installed on the outer cover of the belt conveyor, a connecting rod passing through a through hole at the central position of a horizontally arranged bridge plate at the upper end of the support frame, a handle is provided at the upper end of the connecting rod, and a flow limiting plate that can block large pieces of material is connected to the lower end of the connecting rod, a spring is sleeved on the connecting rod and is located between the lower end of the handle and the upper surface of the bridge plate, at least one limit baffle is provided on the side of the handle, a Z-shaped clip plate for keeping the flow limiting plate in the position limited by the limit baffle is connected to the handle at one end and extends to the bottom of the limit baffle at the other end, and the spring keeps the Z-shaped clip plate below the limit baffle and keeps the flow limiting plate in a suitable open position.

[0007] As a preferred solution, a limit bracket is provided above one end of the bridge plate of the support frame, and there are three limit baffles, which are horizontally spaced apart and provided on the limit bracket.

[0008] As a preferred solution, the support frame includes two vertical side plates located below the two ends of the bridge plate, and the side plates are provided with longitudinal guide grooves with open lower ends, and the flow limiting plate moves up and down in the guide grooves.

[0009] As a preferred solution, the upper end of the connecting rod is threadedly connected to the handle.

[0010] As a preferred solution, the upper end of the connecting rod connected to the handle has an external thread, the handle includes a handle body with a blind hole in the center, an internal threaded sleeve with an internal thread is fixed in the blind hole of the handle body by a locking screw, one end of the Z-shaped clamping plate is fixedly connected to the end of the handle body, the upper end of the connecting rod is threadedly connected to the internal threaded sleeve, and a stop nut is provided at the upper end of the upper end.

[0011] As a preferred solution, the limiting bracket includes a first bracket plate arranged on the bridge plate in the same plane as the side vertical plate on one side, and a second bracket plate connected to the first bracket plate and arranged vertically at the rear, so that the limiting baffle is open near the side of the handle and the front end. When the handle rotates, it drives most of the Z-shaped clamping plates to rotate around the connecting rod, thereby disengaging from the limit of the limiting baffle and then converting the position of the Z-shaped clamping plate.

[0012] The present invention adopts the above-mentioned technical solution, by setting a flow limiting plate at the end of the feeding end of the belt conveyor, specifically, through a gate-shaped support frame, which can be installed on the outer cover of the belt conveyor. At the same time, a through hole is opened in the middle position of the bridge plate of the support frame, and a connecting rod is set through the through hole. The upper end of the connecting rod is connected to the handle, and the lower end is connected to the flow limiting plate. A spring is provided on the connecting rod between the handle and the bridge plate. The spring can keep the flow limiting plate from being lifted and falling. Further, through a Z-shaped card plate connected to the handle at one end, the other end of the Z-shaped card plate is stuck under the side limit baffle, so that the flow limiting plate can be kept at a certain preset height state. In this way, it can prevent the material from entering the belt conveyor and presenting a wave shape, thereby effectively avoiding the occurrence of material spillage, material blockage or material accumulation. The technical solution of the present invention has the advantages of simple structure and convenient operation.

[0013] Furthermore, the present invention provides a plurality of limit baffles of different heights so that the flow limiting plate can be adjusted to different heights. Obviously, the limit baffle can also be one, and its height can be adjusted by a height modulation device, so that the height change can be adjusted steplessly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the preferred embodiments cannot be used to limit the scope of protection of the present invention.

[0019] See also Figure 1-4 The figure shows a quick flow regulating device for solid bulk fluids according to the present invention. The simple flow height limiting device 100 is installed at the feeding port of the belt conveyor 200, located behind the feed hopper 400. The belt conveyor 200 is used to convey materials to the combined sample making machine 300. The quick flow regulating device 100 for solid bulk fluids includes: a support frame 1, which is installed on the outer cover of the belt conveyor 200, see Figure 1, specifically located at the entrance end of the belt conveyor, which is in the shape of a gate, including a horizontal bridge plate 13 and two side plates 14 vertically connected to the two ends of the bridge plate 13, the bottom of the side plate 14 has a horizontal bending portion, and the horizontal bending portion is connected to the outer cover of the belt conveyor 200 through the bracket mounting screw 11; a connecting rod 3 is passed through the through hole in the central position of the bridge plate 13 at the upper end of the support frame 1, and the connecting rod 3 can move up and down in the through hole, and a handle 5 is provided at the upper end of the connecting rod 3, and a flow limiting plate 2 is connected to the lower end of the connecting rod 3, which can prevent large pieces of material from entering the belt conveyor, and a spring 6 is sleeved on the connecting rod 3 and is located between the lower end of the handle 5 and the top of the bridge plate 13. Under the action of the spring 6, the flow limiting plate 2 is kept It is held in a state where it will not fall when lifted; under the action of the spring 6, in order to prevent the flow limiting plate 2 from being lifted too high, or in order to limit the flow limiting plate 2 to a suitable height position, a limit baffle 12 is provided on the side of the handle 5, and a Z-shaped card plate 4 is connected to the handle 5 at one end and extends to the bottom of the limit baffle 12 at the other end, so that the flow limiting plate 2 is maintained at the height position preset by the limit baffle 12. Under the action of the spring 6, the limit baffle 12 and the Z-shaped card plate 4, the flow limiting plate 2 is in a preset suitable open position (height).

[0020] In order to facilitate the installation of the limit baffle 12, a limit bracket 15 is provided above one end of the bridge plate 13 of the support frame 1. There are three limit baffles 12, and the three limit baffles 12 are arranged on the limit bracket 15 at horizontal intervals. The three limit baffles 12 can limit the flow limiting plate 2 to three preset appropriate opening heights. Obviously, their number can be increased or decreased as needed.

[0021] In order to prevent the limiting plate 2 from swinging or rotating when adjusting the height between the heights defined by the plurality of limiting baffles 12 , a longitudinal guide slot 141 with an open lower end is provided on the side plate 14 of the support frame 1 , and the limiting plate 2 moves up and down in the guide slot 141 .

[0022] In order to facilitate the handle 5 to operate the connecting rod and the flow limiting plate 2 to switch between different limit baffles 12, it is best that the upper end of the connecting rod 3 is threadedly connected to the handle 5. At this time, the handle 5 can be rotated, and since the flow limiting plate 2 at the lower end of the connecting rod 3 is limited by the guide long groove 141 and will not rotate, the handle 5 can drive the Z-shaped card plate 4 to rotate, thereby escaping the restriction of the limit baffle 12. At this time, the flow limiting plate 2 can be manually lifted or lowered to the limit baffle 12 position at an appropriate height by the handle 5, and then the handle 5 can be rotated to drive the Z-shaped card plate 4 to rotate and enter the bottom of the limit baffle 12.

[0023] Further, for ease of processing and installation, the upper end portion 31 of the connecting rod 3 connected to the handle 5 has an external thread, the handle 5 includes a handle body 51 with a blind hole in the center, an internal threaded sleeve 53 with an internal thread is fixed in the blind hole of the handle body 51 by a locking screw 52, ​​one end of the Z-shaped clamping plate 4 is fixedly connected to the end of the handle body 51, the upper end portion 31 of the connecting rod 3 is screwed to the internal threaded sleeve 53, and a stop nut 54 is provided at the upper end of the upper end portion 31. The stop screw can limit the handle body 5 and the internal threaded sleeve 53 from rotating too much and falling off from the external threaded portion of the upper end portion 31 of the connecting rod 3.

[0024] Furthermore, preferably, the limiting bracket 15 includes a first bracket plate 151 and a second bracket plate 152 which are arranged on the bridge plate 13 in the same plane as the side vertical plate 14 on one side, that is, the first bracket plate 151 and the side vertical plate 14 can be formed by a single plate, and the second bracket plate 152 is connected to the first bracket plate 151 as a whole, and the second bracket plate 152 is vertically arranged at the rear end of the first bracket plate 151, so that the limiting baffle 12 is open on the side close to the handle 5 and the front end. When the handle 5 rotates, it drives most of the Z-shaped clamping plates 4 to rotate around the connecting rod 3, thereby disengaging from the limit of the limiting baffle 12 and then converting the clamping position of the Z-shaped clamping plate 4.

[0025] The above description is only illustrative and non-restrictive of the present invention. The present invention is intended to provide a quick flow regulating device for solid bulk fluids, which can prevent the material from entering the belt conveyor in a wavy shape by setting a flow limiting plate at the front end of the belt conveyor, thereby effectively avoiding the occurrence of phenomena such as material spillage, material blockage or material accumulation. Those skilled in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined by the claims, such as changing the structure of the limit bracket, increasing or decreasing the number of limit baffles, etc., but all of these will fall within the scope of protection of the present invention.
