It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0035] In one embodiment of the present invention, see Figure 1-Figure 9 A material spreading device for a biomass fuel mesh belt conveyor comprises a mounting frame 1, wherein the mounting frame 1 is configured as a transversely arranged U-shaped frame, a mesh belt conveying mechanism 2 for conveying biomass fuel is mounted on the inner side of the mounting frame 1, a feeding assembly 3 located above the feeding end of the mesh belt conveying mechanism 2 is mounted on the mounting frame 1, a leveling assembly 5 located above the discharging end of the mesh belt conveying mechanism 2 is mounted on the mounting frame 1, the leveling assembly 5 is used for leveling the biomass fuel with different thicknesses, a dust removal assembly 4 located between the feeding assembly 3 and the leveling assembly 5 is also mounted on the mounting frame 1, the dust removal assembly 4 is used for stirring and dust removal of the biomass fuel, and the feeding assembly 3, the dust removal assembly 4 and the leveling assembly 5 are connected via a transmission assembly 6.

[0036] In this embodiment, the middle part of the U-shaped frame is far away from the discharging end of the mesh belt conveyor mechanism 2. Through the setting of the U-shaped frame, the influence of external wind on the biomass fuel feeding can be effectively isolated, and air pollution can be reduced. Through the feeding component 3, the biomass fuel can be continuously V-shaped fed, avoiding the problem of continuous mountain feeding of the existing biomass fuel and inconvenient uniform discharging. Through the leveling component 5, the biomass fuel transported on the mesh belt conveyor mechanism 2 can be leveled. At the same time, since different biomass fuels have different fuel properties, the required discharging speeds are different. According to different usage requirements, the discharging thickness of the leveling component 5 can be flexibly adjusted to meet the discharging requirements of different biomass fuels. Through the dust removal component 4, the biomass fuel transported on the mesh belt conveyor mechanism 2 can be stirred, and at the same time, the dust adhering to the The dust on the biomass fuel is adsorbed to avoid the problem of dust flying during the discharge and falling process of the biomass fuel, thereby reducing air pollution and facilitating the improvement of the air quality of the construction environment. Through the transmission component 6, the linkage between the feeding component 3, the dust removal component 4 and the leveling component 5 can be realized, thereby improving the energy utilization rate. At the same time, the synchronous operation of the feeding component 3, the dust removal component 4 and the leveling component 5 can be realized. According to the different feeding speeds of the biomass fuel, the biomass fuel transported on the mesh belt conveyor mechanism 2 can be processed at the corresponding speed, thereby improving the applicability of the device. Through the controller 7, it is convenient for the staff to control the start and stop of the electrical equipment in the device, and the device has the effects of stable V-shaped feeding, uniform discharge, flexible thickness adjustment, effective dust removal, flexible linkage, reliable structure, convenient operation and simple and practical operation.

[0037] Among them, a plurality of bottom columns 11 are symmetrically installed at the bottom of the installation frame 1, and a moving wheel 12 is installed at the bottom of the bottom column 11. Through the arrangement of the bottom column 11 and the moving wheel 12, the position of the device can be easily moved to meet the use requirements of biomass fuel at different positions. The mesh belt conveyor mechanism 2 is a related existing technology of the mesh belt conveyor device.

[0038] In one embodiment of the present invention, see Figure 1-Figure 3 , Figure 7-Figure 9The feeding assembly 3 includes a discharge box 31 arranged at the end of the mounting frame 1, the discharge box 31 is located at the feeding end of the mesh belt conveyor mechanism 2, a feed pipe 32 is installed on the top of the discharge box 31, and a discharge port 313 is provided at the bottom of the discharge box 31. A feed pipe 32 is slidably provided in the discharge box 31, and a spring 36 is connected between the feed pipe 32 and the inner wall of the discharge box 31. A first rotating rod 34 is rotatably connected to the discharge box 31 located between the feed pipe 32 and the screen plate 33, and a plurality of crushing paddles 35 are distributed circumferentially on the first rotating rod 34. One end of the first rotating rod 34 passes through the side wall of the discharge box 31 and is connected to the movable A second pulley 312 is connected to the outside of the discharge box 31, and a second rotating rod 38 is rotatably connected inside the discharge box 31 between the screening plate 33 and the discharge port 313. One end of the second rotating rod 38 is connected to a rotating motor 37 installed on the outer wall of the discharge box 31. A plurality of dividing paddles 39 that are in movably contact with the inner wall of the discharge box 31 are circumferentially distributed on the second rotating rod 38. One end of the second rotating rod 38 away from the rotating motor 37 passes through the side wall of the discharge box 31 and is connected to the first pulley 310 movably arranged on the outside of the discharge box 31. A first transmission belt 311 is connected between the first pulley 310 and the second pulley 312.

[0039] In this embodiment, the biomass fuel can be guided to the screen plate 33 inside the discharge box 31 through the feed pipe 32. The screen plate 33 is forced to move downward and squeeze the spring 36 downward. The spring 36 is forced and contracts. The staff controls the rotation motor 37 through the controller 7. The rotation motor 37 drives the second rotating rod 38 to rotate. The second rotating rod 38 drives the first rotating rod 34 to rotate synchronously through the first pulley 310, the first transmission belt 311 and the second pulley 312. The first rotating rod 34 can crush the agglomerated part of the biomass fuel by driving the crushing paddle 35 to rotate synchronously.

[0040] The crushed biomass fuel that meets the particle requirements passes through the screening plate 33 and moves to the bottom of the inner side of the discharge box 31. At this time, the content of the biomass fuel above the screening plate 33 is reduced, the downward pressure of the spring 36 is reduced, and the spring 36 extends upward and pushes the screening plate 33 to move upward, which can ensure that the biomass fuel is always within the crushing range of the crushing paddle 35, avoiding the occurrence of a crushing blind area;

[0041] At the same time, the second rotating rod 38 drives the dividing paddle 39 to rotate, and the dividing paddle 39 can divide the biomass fuel passing through the screen plate 33 into different areas. Through the cooperation between the two adjacent dividing paddles 39 and the inner wall of the discharge box 31, the single loading amount of the biomass fuel can be quantitatively processed. At the same time, through the V-shaped dividing paddle 39, when the dividing paddle 39 rotates clockwise and drives the biomass fuel located between the two adjacent dividing paddles 39 to move to the discharge port 313, the biomass fuel corresponding to the two ends of the discharge port 313 will first fall onto the mesh belt of the moving mesh belt conveyor mechanism 2, and the biomass fuel corresponding to the middle of the discharge port 313 will finally move down to the mesh belt of the moving mesh belt conveyor mechanism 2. The biomass fuel dropped on the mesh belt is distributed in a V-shape, which can achieve uniform distribution of the biomass fuel, avoid the formation of small hills of biomass fuel, and facilitate stable discharge of the biomass fuel.

[0042] The bottom of the discharge box 31 is semi-cylindrical, and the number of the distributing paddles 39 is at least five.

[0043] In one embodiment of the present invention, see Figure 1-Figure 2 , Figure 6 and Figure 8 The leveling assembly 5 includes a mounting bracket 51 mounted on the mounting frame 1, the mounting bracket 51 is located at one end of the mounting frame 1 away from the feeding assembly 3, the mounting bracket 51 is rotatably connected to a third rotating rod 52, the third rotating rod 52 is symmetrically provided with a cam 53, the cam 53 is provided with an annular groove 54, a sliding column 55 is slidably provided in the annular groove 54, a first lifting column 57 is symmetrically and slidably provided on the mounting bracket 51, the first lifting column 57 is provided with a connecting plate 56 connected to the sliding column 55 at one end close to the cam 53, a lifting plate 58 is connected to one end of the first lifting column 57 close to the mesh belt, second lifting columns 59 are symmetrically and slidably provided on both sides of the lifting plate 58, and a screed plate 510 is connected to one end of the second lifting column 59 close to the mesh belt, one of the second lifting columns 59 is provided with a straight tooth groove 511, an adjusting motor 513 is installed on the lifting plate 58, and a transmission gear 512 meshing with the straight tooth groove 511 is connected to the adjusting motor 513.

[0044] In this embodiment, the staff controls the rotating motor 37 to work through the controller 7, and the rotating motor 37 drives the second rotating rod 38 to rotate. The second rotating rod 38 drives the third rotating rod 52 to rotate synchronously through the transmission assembly 6, and the cam 53 drives the cam 53 to rotate. The cam 53 drives the first lifting column 57 to reciprocate in the vertical direction by sliding cooperation with the sliding column 55 through the annular groove 54 and the first lifting column 57 and the mounting bracket 51. The first lifting column 57 drives the lifting plate 58 to rise and fall synchronously, and the lifting plate 58 drives the screed plate 510 to rise and fall synchronously by meshing the transmission gear 512 and the straight tooth groove 511 and connecting the second lifting column 59 with the screed plate 510. The screed plate 510 performs a reciprocating lifting and lowering process on the biomass fuel on the mesh belt to level the biomass fuel, thereby achieving uniform processing of the biomass fuel and avoiding different discharge amounts of the biomass fuel at different positions.

[0045] Since different types of biomass fuels have different fuel properties and their required discharge volumes are also different, the staff can adjust the height of the screed plate 510 according to the combustion characteristics of the corresponding types of biomass fuels, thereby adjusting the discharge thickness of the biomass fuel; specifically, the control and adjustment motor 513 works in the forward direction, the adjustment motor 513 drives the transmission gear 512 to rotate clockwise, and the transmission gear 512 drives the screed plate 510 downward by meshing with the straight tooth groove 511 and the second lifting column 59 and the lifting plate 58 slidingly cooperate, which can meet the reduction of the discharge thickness of the biomass fuel; the control and adjustment motor 513 works in the reverse direction, the adjustment motor 513 drives the transmission gear 512 to rotate counterclockwise, and the transmission gear 512 drives the screed plate 510 upward by meshing with the straight tooth groove 511 and the second lifting column 59 and the lifting plate 58 slidingly cooperate, which can meet the increase of the discharge thickness of the biomass fuel;

[0046] There are several through holes distributed on the leveling plate 510, so as to evenly level the protruding biomass fuel pile.

A purification box 48 is provided on the installation box 41, and an air suction module (not shown in the figure) is provided in the purification box 48. The air suction module is respectively connected with one end of the corresponding rotating drum 43 away from the connecting drum 45 through an air guide pipe 47, and a filter screen 49 is installed on a side wall of the purification box 48 away from the air suction module.

[0048] In this embodiment, the staff controls the rotating motor 37 to work through the controller 7, and the rotating motor 37 drives the second rotating rod 38 to rotate. The second rotating rod 38 drives the worm 42 to rotate synchronously through the transmission assembly 6. The worm 42 drives the rotating drum 43 to rotate by meshing with the worm wheel 44.

The air intake module works, and the air mixed with dust on the biomass fuel enters the purification box 48 through the suction hole 461-connecting tube 45-rotating drum 43 and the air guide pipe 47 in turn. The air in the purification box 48 is discharged after being filtered by the filter net 49, which can realize the centralized collection of dust, avoid the influence of dust on the fuel effect of biomass fuel, and at the same time avoid the pollution problem of dust flying in the air. In addition, through the stirring of the rotating tube 46, it is convenient to level the biomass fuel on the mesh belt in the subsequent process.

[0049] There are three rotating drums 43 and they are distributed along a direction perpendicular to the movement of the mesh belt, so as to facilitate comprehensive stirring of the biomass fuel.
