Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a raw material conveying device for biomass pellet fuel production. Background Technology

[0002] Biomass pellets are a type of biomass energy source that primarily uses agricultural and forestry processing waste such as sawdust, straw, rice husks, and bark as raw materials. Through pretreatment and processing, these materials are solidified into high-density pellet fuel. During the biomass fuel processing, the materials need to be transported between various stages, mainly via conveyor belts.

[0003] For example, patent CN215665439U discloses a material conveying device for biomass pellet fuel production, including a support mechanism. The upper end of the support mechanism is equipped with a conveying mechanism for conveying biomass fuel, and a height adjustment mechanism connected between the support mechanism and the conveying mechanism for adjusting the elevation angle of the conveying mechanism. The conveying mechanism is rotatably connected to the support mechanism. The support mechanism includes a base frame with support wheels at its four lower corners and a support column on one side of its upper end, connected to the conveying mechanism. The conveying mechanism includes support plates, with a secondary drive roller positioned between the support plates near the support column and a primary drive roller positioned between the support plates away from the secondary drive roller. The height adjustment mechanism allows for adjustment of the conveying mechanism's elevation height, facilitating different conveying heights and improving ease of use.

[0004] However, the conveying device in the above technology still has the following problems:

[0005] Although the height of one end of the conveyor can be adjusted to achieve different conveying heights, when materials such as bark and branches accumulate on the conveyor belt, they may fall off the sides of the belt, resulting in material waste. This requires additional cleaning and collection of the fallen materials, increasing the workload of the conveying operation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a raw material conveying device for biomass pellet fuel production, which can reduce the possibility of material falling off both sides of the conveyor belt, making the material conveying smoother.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a raw material conveying device for biomass pellet fuel production, comprising a conveyor belt installed between two support plates, baffles connected to the upper surfaces of the two support plates, material blocking assemblies connected to the side of the two baffles near the conveyor belt, the other ends of the two material blocking assemblies being connected to the two support plates respectively, a flipping assembly connected to the top of the two support plates, the flipping assembly being connected to the adjacent baffle, and a driving assembly connected to both ends of the two support plates on the side furthest from each other, the driving assembly being connected to the adjacent baffle.

[0008] Furthermore, the baffle assembly includes a baffle plate and two trapezoidal strips. The two trapezoidal strips are fixedly connected to both sides of the baffle plate. The baffle plate is provided with trapezoidal grooves at one end adjacent to the adjacent support plate and on the side near the conveyor belt. The two trapezoidal strips are slidably connected to the two trapezoidal grooves respectively.

[0009] Furthermore, the baffle is made of wear-resistant rubber.

[0010] Furthermore, the flipping assembly includes several flipping blocks, and several flipping grooves are provided on the side of the baffle near the adjacent support plate. Several flipping blocks are fixedly connected to several flipping grooves respectively through rotating shafts, and the side of several flipping blocks away from the flipping grooves is fixedly connected to the adjacent support plate.

[0011] Furthermore, the trapezoidal groove on the side of the baffle is located above several flip grooves.

[0012] Furthermore, the drive assembly includes a hydraulic rod, a U-shaped block, and two connecting rods. The output end of the hydraulic rod is fixedly connected to a connecting block, which is rotatably connected to the inner walls of both sides of the U-shaped block via a rotating shaft. The outer wall of the U-shaped block is fixedly connected to an adjacent baffle. The bottom of the hydraulic rod is fixedly connected to a base, which is rotatably connected to the two connecting rods via a rotating shaft. The ends of the two connecting rods away from the base are fixedly connected to an adjacent support plate.

[0013] Furthermore, a support block is fixedly connected to the bottom of each of the two connecting rods, and the support block is fixedly connected to the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of raw material conveying device for biomass pellet fuel production can block the material being conveyed on the conveyor belt by installing baffles on the support plates on both sides of the conveyor belt, thereby preventing the material from falling off the sides of the conveyor belt during conveying and making the material conveying more stable and smooth.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1 - Figure 6 A raw material conveying device for biomass pellet fuel production includes a conveyor belt 2 installed between two support plates 1. Baffles 3 are connected to the upper surfaces of both support plates 1. Material blocking assemblies are connected to the side of each baffle 3 closest to the conveyor belt 2. The other ends of the two material blocking assemblies are respectively connected to the two support plates 1. A flipping assembly is connected to the top of each support plate 1. The flipping assembly is connected to the adjacent baffle 3. Drive assemblies are connected to the two ends of the two support plates 1 on the side furthest from each other. The drive assemblies are connected to the adjacent baffle 3.

[0025] like Figure 1 - Figure 6 As shown, the raw material conveying device for biomass pellet fuel production in this utility model is structurally similar to existing raw material conveying devices for biomass pellet fuel production, such as the material conveying device for biomass pellet fuel production disclosed in patent announcement number CN215665439U. The main improvement of this utility model is to prevent material from falling from both sides of the conveyor belt 2 during material conveying. Figures 1 to 6As shown, the raw material conveying device for biomass pellet fuel production of this utility model, when in use, can block the raw materials conveyed on the conveyor belt 2 by installing baffles 3 on the top of the support plates 1 on both sides, preventing the conveyed raw materials from falling off the sides of the conveyor belt 2 and improving the stability of the conveyor belt 2 for conveying raw materials. At the same time, when there is a lot of raw material on the conveyor belt 2, the baffles 3 on both sides can be flipped outwards appropriately by the flipping component, thereby forming a wider raw material conveying space above the conveyor belt 2, which facilitates the smoother conveying and movement of the raw materials, avoids the baffles 3 on both sides squeezing the raw materials in the middle, increasing friction, causing the conveying and movement of the raw materials to slow down, and improves the raw material conveying efficiency.

[0026] like Figure 1 - Figure 6 As shown, the baffle assembly includes a baffle plate 4 and two trapezoidal strips 5. The two trapezoidal strips 5 are fixedly connected to both sides of the baffle plate 4. The baffle plate 3 has trapezoidal grooves 101 on one end adjacent to the adjacent support plate 1 and on the side near the conveyor belt 2. The two trapezoidal strips 5 are slidably connected to the two trapezoidal grooves 101 respectively. Since the baffle plate 3 and the support plate 1 need to be rotated at an angle, there will inevitably be a certain gap at the connection position. At this time, the baffle plate 4 is connected and fixed to the support plate 1 and the trapezoidal grooves 101 on the side of the baffle plate 3 through the trapezoidal strips 5 on both sides, thereby sealing the connection gap between the baffle plate 3 and the support plate 1, thus preventing the production raw materials from entering the gap and affecting the rotation operation of the baffle plate 3 on the support plate 1.

[0027] like Figure 1 - Figure 4 As shown, the baffle plate 4 is made of wear-resistant rubber. During the transportation of raw materials, friction will occur between the baffle plate 4 and the baffle plate 4. Using wear-resistant rubber to make the baffle plate 4 can extend its service life and reduce the replacement frequency of the baffle plate 4.

[0028] like Figure 1 - Figure 6 As shown, the flipping assembly includes several flipping blocks 6. A plurality of flipping grooves 301 are formed on the side of the baffle 3 closest to the adjacent support plate 1. The flipping blocks 6 are fixedly connected to the flipping grooves 301 via rotating shafts. The sides of the flipping blocks 6 furthest from the flipping grooves 301 are also fixedly connected to the adjacent support plate 1. The baffle 3 rotates between itself and the multiple flipping blocks 6 on the top of the support plate 1 via the flipping grooves 301 and the rotating shafts, thereby achieving the angle flipping of the baffle 3.

[0029] like Figure 1 - Figure 6As shown, the trapezoidal groove 101 on the side of the baffle 3 is located above several tilting grooves 301. By placing the trapezoidal groove 101 on the baffle 3 above the tilting grooves 301, the installed baffle plate 4 can cover the tilting grooves 301, thereby preventing raw materials from falling into the tilting grooves 301 and affecting the normal tilting of the baffle 3.

[0030] like Figure 1 - Figure 6 As shown, the drive assembly includes a hydraulic rod 7, a U-shaped block 8, and two connecting rods 9. A connecting block 10 is fixedly connected to the output end of the hydraulic rod 7. The connecting block 10 is rotatably connected to the inner walls of both sides of the U-shaped block 8 via a rotating shaft. The outer wall of the U-shaped block 8 is fixedly connected to an adjacent baffle 3. A base 11 is fixedly connected to the bottom of the hydraulic rod 7. The base 11 is rotatably connected to the two connecting rods 9 via a rotating shaft. The ends of the two connecting rods 9 furthest from the base 11 are fixedly connected to an adjacent support plate 1. The extension or retraction of the hydraulic rod 7 drives the U-shaped block 8 to move, thereby achieving the flipping operation of the baffle 3. The two connecting rods 9 support the bottom of the hydraulic rod 7 via the rotating base 11. Alternatively, an electric actuator can be used to replace the hydraulic rod 7 to achieve automatic extension and retraction.

[0031] like Figure 1 - Figure 6 As shown, support blocks 12 are fixedly connected to the bottom of the two connecting rods 9, and the support blocks 12 are fixedly connected to the support plate 1. Fixing the support blocks 12 to the bottom of the two connecting rods 9 and fixing the support blocks 12 to the support plate 1 further improves the support for the hydraulic rods 7, thereby increasing the support force for the baffle 3. This prevents excessive material from forming heavy pressure on the baffle 3 when it tilts, which could cause deformation of the support structure and improve the support strength.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
