Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to an adjustable material conveying head collecting device. Background Art

[0002] During the material conveying process, the head funnel is the first point where the material flow enters the drop pipe, and it is also a very critical starting point. The impact angle of the material flow at the impact point of the traditional funnel is above 40 degrees. The result is that the huge impact force damages the funnel, and a large amount of dust is generated after the material is impacted and dispersed.

[0003] The collector is installed at the drum discharge port, collecting and restricting the moving material flow at a low impact angle. This reduces the impact force of the material flow on the collector trough wall, ensuring a smooth material flow and preventing material from directly impacting the head funnel, causing blockages and dust. Traditional collectors lack the ability to automatically adjust their front and rear position and angle based on changes in load or feeder belt speed. This makes it impossible to ensure that the material flows into the collector in a smooth parabolic trajectory, which can easily cause impact wear on the collector, damage and scratches on the feeder belt, and blockages.

[0004] Defects and shortcomings of existing technology:

[0005] The following are the commonly used aggregate devices on the market:

[0006] (1) Manually adjustable aggregate device: This type of aggregate device is structured such that the aggregate base plate is connected to the back spindle and is vertically installed inside the head cover. A manual adjustment device is provided at the lower end of the aggregate, and the aggregate can rotate around its back spindle. During the material conveying process, the angle of the aggregate can be adjusted by the manual adjustment device, but the front and rear position of the aggregate cannot be adjusted. When the load or belt speed of the feed conveyor belt is unstable, the aggregate device cannot be adjusted in time, and the material impacts the aggregate, abrading the surface of the feed conveyor belt, and in severe cases, causing blockage.

[0007] (2) Flexible aggregate device: The structure of this aggregate device is that the aggregate base plate is connected to the back main shaft and is vertically installed inside the head cover. A flexible buffer device is set at the lower end of the aggregate, and the aggregate can rotate around its back main shaft. During the material conveying process, the repeated vibration of the flexible buffer device at the lower end of the aggregate can reduce the impact force of the material to a certain extent. Ordinary materials can fall quickly after impacting the aggregate, but when encountering materials with high viscosity or high water content, they will hang on the surface of the aggregate. Subsequent materials impact and compact the previous materials. Due to the stronger adhesion between the materials, more and more materials will accumulate on the surface of the aggregate, and the material flow diameter will become smaller and smaller, resulting in blockage. Utility Model Content

[0008] The purpose of this utility model is to provide an intelligent adjustment aggregate device suitable for various working conditions for bulk material conveying industries such as various metal mines, ports, electric power, cement, etc., because the on-site conveyor belt carrying capacity and belt speed are unstable, the material particle size is different, the characteristics are diverse, and the transfer point drop is high. Conventional aggregate devices cannot adjust the relative position in real time according to the material conveying conditions, which can easily cause impact wear of the aggregate, wear of the conveyor belt surface, material turning over the aggregate, material blockage and frequent maintenance. The utility model has the characteristics of simple and convenient structure, high reliability and easy maintenance.

[0009] In order to achieve the above-mentioned purpose, the present invention is specifically realized through the following technical solutions:

The top of the collecting container 2 corresponds to the feed port 11, and the bottom corresponds to the funnel 5.

[0032] The head collecting device of the present invention is installed at the drum discharge port. The curvature and shape of the collector 2 are determined by EDEM simulation software analysis to ensure that the material flow enters smoothly with a parabolic trajectory of no more than 30 degrees. A low impact angle is used to collect and limit the moving material flow, which can reduce the impact force on the groove wall of the collector 2, inhibit the generation of dust, and avoid head blockage and accumulation caused by a sudden drop in material flow speed.

[0033] A movable spindle 21 is provided in the middle of the back side of the material collector 2, and a U-shaped rotary support 22 is provided at the bottom. Two sets of slide rail assemblies 6 are longitudinally installed inside the head cover 1.

[0036] The front and rear adjustment mechanism 3 adopts a structural design in which a motor and an NMRV reducer drive two sets of worm gear screw elevators. The extension and retraction of the screw head of the first worm transmission component 33 are controlled by the forward and reverse rotation of the motor to realize the forward and backward movement of the collector 2 on the dovetail groove linear guide 61, which not only ensures the synchronization, stability and reliability of the operation of the first worm transmission component 33, but also facilitates the installation, maintenance and replacement of the entire collecting device, saving time and effort, with a novel design and convenient and fast operation.

The shaft seats 23 at both ends (rotating parts) of the active spindle 21 of the material collector 2 are equipped with seated vertical bearings. The pin connection of the rotating part is equipped with a copper sleeve, and the connection at both ends is equipped with copper gaskets, which can effectively ensure the smooth operation of the material collector 2 during the angle adjustment process.

[0039] Preferably, the sleeve assembly 7 includes an anti-loosening bolt 71, a sleeve 72, a slotted nut 73 and a cotter pin 74.

[0040] Both the front-to-rear adjustment mechanism 31 and the angle adjustment mechanism 41 utilize a motor-driven worm gear lift. A flexible dust cover is installed above the screw, while a rigid dust cover is installed below the screw to prevent material and dust from falling onto the screw surface and affecting normal operation of the equipment. Screw lifts offer high load capacity, compact structure, high transmission efficiency, smooth operation, long service life, high precision, safe and reliable operation, and a self-locking function.
