Description
Technical Field
[0001] This utility model relates to the field of mining loaders, and in particular to a material collection device for mining loaders. Background Technology
[0002] Mining excavator loaders are mechanical equipment used in narrow tunnel mining environments. They are mainly used in the crushing, conveying, and loading of crushed stone in mines such as phosphate mines, iron mines, and coal mines and in tunnel engineering. They are widely used for material loading, unloading, and transfer in mining and tunnel construction scenarios. Depending on different working conditions and needs, mining loaders can be divided into various types, and they have the characteristics of high efficiency, safety, and environmental protection.
[0003] Traditional material collection devices typically employ simple conveyor belt structures, which suffer from problems such as high dust levels during loading and unloading, endangering worker health and polluting the environment. Additionally, large pieces of material tend to accumulate at the feed inlet, causing blockages that affect continuous operation efficiency. Furthermore, the material height is not adjustable, which can lead to scattering or belt overload safety issues due to excessively high material stacking. Therefore, a material collection device for mining loaders is proposed to address the problems mentioned in the background technology. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a material collection device for mining loaders. It effectively disperses lumpy materials through a dispersing and mixing frame to prevent feed blockage. It adopts a dual dust removal system that combines negative pressure filtration and atomization dust suppression to significantly reduce dust pollution during operation. It is equipped with an adjustable height limit device to limit the height of materials to prevent excessive material stacking from causing safety problems. It can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a material collection device for a mining loader, comprising a conveyor frame and a support frame;
[0006] Conveying frame: A material collection frame is fixedly installed on the left side. The bottom surface of the conveying frame and the material collection frame is provided with a base. A belt conveyor is installed inside the base. There are two brackets, which are fixed on the front and rear sides of the top surface of the material collection frame respectively. The top surface of the bracket is connected to the bottom end of the motor frame. A motor is placed on the top surface of the motor frame. The output shaft of the motor is connected to the top of the rotating dispersing and mixing frame inside the bracket. Dust removal units are provided on both the front and rear sides of the material collection frame. A height limiting unit is provided on the rear side of the material collection frame.
[0007] It also includes a guide plate and a controller. The guide plate is fixed on the left side of the collecting frame, and the controller is installed on the front side of the conveyor frame. The input end of the belt conveyor and the motor is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of an external power supply.
[0008] The set guide plate guides the material to fall into the collection rack, and the belt conveyor can transport and collect the material. The motor drives the dispersing and mixing rack to break up the clumps of material, avoid the feed inlet from being blocked, and thus improve the continuous operation efficiency of the belt conveyor.
[0009] Furthermore, the dust removal unit includes a handle, a filter box, a housing, a negative pressure fan, a mesh trough, and a filter screen. There are two housings, each fixed to the front and rear sides of the material collection rack. A filter box is inserted into a groove on the top surface of the housing, and a handle is installed on the top surface of the filter box. A negative pressure fan is installed on the surface of the housing. There are two mesh troughs, each located on the front and rear sides inside the material collection rack. The mesh troughs are connected to the housing, and a filter screen is inserted inside each mesh trough. The input end of the negative pressure fan is electrically connected to the output end of the controller. Activating the negative pressure fan, in conjunction with the filter box, adsorbs and filters dust from the material during loading. The filter screen inserted inside the mesh trough prevents larger materials from entering the housing and causing blockages that could affect subsequent dust removal efficiency.
[0010] Furthermore, the dust removal unit also includes an atomizing nozzle, a telescopic rod, a flow regulating valve, a liquid pump, and a dust suppression liquid tank. There are two telescopic rods, fixed to the rear side of the conveyor frame, with their top ends connected to the rear side of the bottom surface of the atomizing nozzle. The dust suppression liquid tank is fixed to the front side of the conveyor frame. A liquid pump is installed on the top surface of the dust suppression liquid tank. The outlet pipe of the liquid pump is connected to the inlet of each of the two atomizing nozzles. A flow regulating valve is installed on the outside of the outlet pipe of the liquid pump. The flow regulating valve and the input end of the liquid pump are electrically connected to the output end of the controller. Pulling the telescopic rod adjusts the height of the atomizing nozzle, and starting the liquid pump causes the dust suppression liquid inside the dust suppression liquid tank to pass through the atomizing nozzle, forming a water mist barrier to suppress dust.
[0011] Furthermore, the height limiting unit includes a top plate, an inclined guide block, a fixed seat, a lifting rod, a screw, and a rotating wheel. The fixed seat is fixed to the rear side of the material collection rack. The lifting rod is slidably installed inside the fixed seat. A rotating wheel is provided on the bottom surface of the fixed seat. The top end of the rotating wheel is connected to the bottom end of the screw. The screw is threadedly connected to the screw hole in the middle of the lifting rod. The top end of the lifting rod is connected to the rear side of the bottom surface of the top plate. An inclined guide block is fixed on the bottom surface of the top plate. Rotating the rotating wheel drives the screw to rotate to adjust the height of the inclined guide block. This can change the height of the material to prevent the material from piling up too high and falling, causing safety accidents or overloading damage to the belt conveyor.
[0012] Furthermore, it also includes a liquid level sensor and a dust sensor. The liquid level sensor is installed on the surface of the dust suppression liquid tank and fixed to the top surface of the top plate. The output terminals of the liquid level sensor and the dust sensor are electrically connected to the input terminal of the controller. The dust sensor monitors the dust concentration in real time, thereby automatically adjusting the speed of the negative pressure fan and the flow rate of the flow regulating valve to improve the dust removal effect. The liquid level sensor can detect the liquid level inside the dust suppression liquid tank to facilitate timely replenishment of liquid by personnel.
[0013] Furthermore, it also includes a wireless transmitter, which is fixed to the rear side of the conveyor frame. The output of the wireless transmitter is electrically connected to the input of the controller. The wireless transmitter can transmit the detected data to the personnel's electronic devices to facilitate the personnel to view the data and make subsequent adjustments.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The material collection device of this mining loader has the following advantages:
[0015] The material is guided by the guide plate to fall into the collection rack. The belt conveyor can then transport and collect the material. The motor drives the dispersing and mixing rack to break up any clumps of material, preventing blockage at the feed inlet and thus improving the continuous operation efficiency of the belt conveyor.
[0016] By starting the negative pressure fan in conjunction with the filter box, dust in the materials during loading is adsorbed and filtered. The filter screen inserted inside the mesh groove can prevent large materials from entering the shell and causing blockage, which would affect the subsequent dust removal effect. The liquid pump is started to form a water mist barrier through the atomizing nozzle to suppress dust.
[0017] The height of the inclined guide block is adjusted by rotating the rotating wheel to drive the screw to rotate. This changes the height of the material to prevent it from piling up too high and falling, or causing the belt conveyor to overload and be damaged. Attached Figure Description

[0025] Please see Figure 1-4 This embodiment provides a technical solution: a material collection device for a mining loader, including a conveyor frame 1 and a support 9;
[0026] Conveyor frame 1: A material collection frame 4 is fixedly installed on the left side. A base 5 is provided on the bottom surface of both the conveyor frame 1 and the material collection frame 4. A belt conveyor 6 is installed inside the base 5.

A filter screen 26 is inserted inside the mesh slot 25. The input end of the negative pressure fan 24 is electrically connected to the output end of the controller 15. When the negative pressure fan 24 is started, it works with the filter box 22 to adsorb and filter the dust in the material during the loading process. The filter screen 26 inserted inside the mesh slot 25 can prevent large materials from entering the outer shell 23 and causing blockage, which would affect the subsequent dust removal effect. The dust removal unit 2 also includes an atomizing spray pipe 27, a telescopic rod 28, a flow regulating valve 29, a liquid pump 210, a dust suppression liquid tank 211, and a telescopic rod 29.

Starting the liquid pump 210 causes the dust suppression liquid inside the dust suppression liquid tank 211 to form a water mist barrier through the atomizing nozzle 27 to achieve the dust suppression effect. The rear side of the collection rack 4 is provided with a height limiting unit 3. The high unit 3 includes a top plate 31, an inclined guide block 32, a fixed seat 33, a lifting rod 34, a screw 35, and a rotating wheel 36.

The bottom surface of the top plate 31 is fixed with an inclined guide block 32. Rotating the rotating wheel 36 drives the screw 35 to rotate to adjust the height of the inclined guide block 32. This can change the height of the material to prevent the material from piling up too high and falling, or the belt conveyor 6 from being overloaded and damaged.
[0027] The system also includes a guide plate 11 and a controller 15. The guide plate 11 is fixed to the left side of the collecting rack 4, and the controller 15 is installed on the front side of the conveyor frame 1. The input terminals of the belt conveyor 6 and the motor 8 are electrically connected to the output terminal of the controller 15, and the input terminal of the controller 15 is electrically connected to the output terminal of an external power supply. The guide plate 11 guides the material to fall into the collecting rack 4, and the belt conveyor 6 can transport and collect the material. The motor 8 is started to drive the dispersing and mixing rack 10 to disperse the clumps of material, preventing the feed inlet from being blocked, thereby improving the continuous operation efficiency of the belt conveyor 6. The system also includes a liquid level sensor 12 and a dust sensor 13. The liquid level sensor 12 is installed on the surface of the dust suppression liquid tank 211. The liquid level sensor 12 is fixed on the top surface of the top plate 31. The output terminals of the liquid level sensor 12 and the dust sensor 13 are electrically connected to the input terminal of the controller 15. The dust sensor 13 monitors the dust concentration in real time, thereby automatically adjusting the speed of the negative pressure fan 24 and the flow rate of the flow regulating valve 29 to improve the dust removal effect.

[0028] The working principle of the material collection device for the mining loader provided by this utility model is as follows: First, the conveyor frame 1 is installed on the top surface of the mining loader. The guide plate 11 guides the material to fall into the collection frame 4. The belt conveyor 6 can then transport and collect the material. The motor 8 is started to drive the dispersing and mixing frame 10 to disperse the clumps of material, preventing blockage of the feed inlet and thus improving the continuous operation efficiency of the belt conveyor 6. The rotating wheel 36 drives the screw 35 to rotate to adjust the height of the inclined guide block 32. This can change the height of the material to prevent the material from piling up too high and falling, or the belt conveyor 6 from being overloaded and damaged.

During the loading process, dust in the material is adsorbed and filtered, while the filter screen 26 inserted inside the mesh trough 25 can prevent large materials from entering the shell 23 and causing blockage, thus affecting the subsequent dust removal effect. At the same time, the liquid pump 210 is started to form a water mist barrier through the atomizing nozzle 27 to suppress dust in the dust suppression liquid tank 211. The dust sensor 13 is set to monitor the dust concentration in real time, thereby automatically adjusting the speed of the negative pressure fan 24 and the flow rate of the flow regulating valve 29 to improve the dust removal effect. The liquid level sensor 12 can detect the liquid level inside the dust suppression liquid tank 211 to facilitate timely replenishment of liquid by personnel.
