Description

Technical Field

[0001] The invention relates to the technical field of feeding devices, in particular to a feeding device suitable for biomass particles. Background Art

[0002] Biomass pellets are a type of solid fuel made from processed organic biomass materials, usually in a cylindrical shape. They are made by compressing biomass raw materials (such as wood, agricultural waste, energy crops, etc.), and have the characteristics of high energy density, easy storage and transportation. They are an important part of renewable energy. Some biomass pellets are directly stacked on the ground after pelletizing, which is the most convenient way. No additional equipment or space is required for special storage arrangements, which can save manpower and material costs. When operations such as loading and warehousing are required, biomass pellets are often transported through portable higher hose suction machines.

[0003] At present, in the actual operation scene of using hose suction machine to transport biomass pellets, the common feeding operation mode exposes many disadvantages. One of the more common practices is to place the feeding head of the hose suction machine next to the pile of biomass pellets. In this process, in order to ensure that the suction machine can continuously and stably suck the material, the worker has to hold tools such as rakes or shovels throughout the process to continuously push the biomass pellets to the top of the feeding head. This operation not only requires workers to invest a lot of time and energy, but also has great labor intensity. In addition, the efficiency of the entire process is extremely low, which seriously affects the transportation progress of the biomass pellets; the other is to insert the feeding head of the hose suction machine into the bottom of the piled biomass pellets. However, due to the large pressure applied to the feeding head by the piled biomass pellets, and because the biomass pellets are mostly cylindrical, at the bottom of the pile, the pellets squeeze each other and easily form an arch structure, that is, the "bridging" phenomenon. When the suction machine sucks the pellets, this arch structure may prevent the pellets from smoothly entering the suction pipe, thereby causing blockage. Based on this, a feeding device suitable for biomass pellets is proposed. Summary of the invention

[0004] In order to solve the above technical problems, the embodiment of the present application provides a feeding device suitable for biomass particles, including a hose suction machine body, a feeding head is provided at the feeding end of the hose suction machine body, and also includes:

[0006] A plurality of material holding plates, wherein the plurality of material holding plates are fixed on the outer circumference of the feed head in an annular array;

[0007] A material guide assembly is arranged at the rear section of the material receiving surface of the material receiving plate, and the material guide assembly includes a hinged movable material guide plate. When the material receiving plate rotates from the bottom end to the upper end, the movable material guide plate can be automatically switched to deflect downward and then return to its original position under the action of gravity;

[0008] The follower knocking assembly is arranged on the first connecting rod, and the material holding plate can be knocked by the follower knocking assembly when the movable material guide plate deflects downward or returns to its original position after deflecting downward.

[0012] In some embodiments, the follower striking assembly includes a second striking piece fixed at both ends of the first connecting rod, and when the return spring is in a natural state, the striking end of the second striking piece is in contact with the material receiving surface of the material receiving plate.

[0013] In some embodiments, the follower knocking assembly also includes a second connecting rod rotatably connected to the material receiving surface of the material receiving plate, the second connecting rod is parallel to the first connecting rod, and a plurality of first knocking members are equidistantly installed on the outside of the second connecting rod. When the return spring is in a natural state, there is a knocking distance between the knocking end of the first knocking member and the material receiving surface of the material receiving plate, and a gear connecting member is connected between the second connecting rod and the first connecting rod, and the opposite rotation of the movable material guide plate and the first knocking member is realized through the gear connecting member.

[0014] In some embodiments, the gear connecting member includes a first gear installed on a first connecting rod and a second gear installed on a second connecting rod, and the first gear and the second gear are meshingly connected.

[0015] In some embodiments, an annular guide groove is formed on the inner wall of the sleeve, an annular guide bar is fixed to the outside of the connecting rigid tube, and a first ball is fixed to the outside of the annular guide bar.

[0016] In some embodiments, it also includes a rotating connector connected to the inside of the end of the feed head, the rotating connector includes a connecting column for connecting a coil spring, a movable column is connected to the connecting column, a receiving groove for accommodating the connecting column is opened inside the end of the feed head, a movable groove is opened inside the receiving groove, and the movable column rotates to cooperate with the movable groove.

[0020] 2. Intelligent material guiding improves efficiency: The movable material guiding plate of the material guiding assembly works with the return spring to automatically control the blocking and release of biomass particles during the rotation of the material holding plate, increase the material receiving capacity of the feed head, and improve the feeding efficiency.

[0021] 3. Automatic cleaning and anti-adhesion: When the movable material guide plate deflects and returns to its original position, the follow-up knocking component knocks the material holding plate through the first knocking piece and the second knocking piece, effectively removing biomass particles with excessive humidity, preventing adhesion, and ensuring the continuous normal operation of the equipment.

[0022] 4. Reduce the risk of blockage: During the knocking process, the first knocking piece can also move the biomass particles to make the particles more evenly distributed, significantly reducing the probability of blockage between the movable guide plate and the material holding plate, ensuring a stable and efficient conveying process.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 9As shown, the present invention provides a technical solution: a feeding device suitable for biomass particles, including a hose suction machine body 1, a feeding head 2 is provided at the feeding end of the hose suction machine body 1, the principle of the hose suction machine is that after the driving motor is started, the driving motor drives the spiral spring to rotate, and the biomass particles at the feeding head 2 rise along the spiral rise angle direction of the spring under the action of the rotating spring, and automatically unload due to gravity when reaching the discharge port, the outside of the feeding head 2 is provided with a plurality of feeding ports, and also includes a rotating component 3, a material holding plate 4 and a material guiding component 6, the rotating component 3, the material holding plate 4 and the ... The moving component 3 is used to connect the feed end of the hose of the hose suction machine body 1 and the feed head 2, and realizes the rotation feeding of the feed head 2 through the rotating component 3; there are multiple material receiving plates 4, and the material receiving plates 4 are preferably of arc structure, and multiple material receiving plates 4 are fixed on the outer circumference of the feed head 2 in a ring array; the material guiding component 6 is arranged at the rear section of the material receiving surface of the material receiving plate 4, and the material guiding component 6 includes a hinged movable material guiding plate 61. In the process of the material receiving plate 4 rotating from the bottom end to the upper end, the movable material guiding plate 61 can be automatically switched to deflect downward and then return to its original position under the action of gravity.

[0040] Among them, see Figure 3 and Fig. 9 As shown, the rotating assembly 3 includes a connecting hard pipe 31 fixed to the hose feeding end of the hose suction machine body 1, a sleeve 34 is fixed to the end of the feed head 2, and the sleeve 34 is rotatably connected to the connecting hard pipe 31, wherein an annular guide groove 36 is provided on the inner wall of the sleeve 34, an annular guide bar 37 is fixed to the outside of the connecting hard pipe 31, and a first ball 38 is fixed to the outside of the annular guide bar 37. When the feed head 2 rotates, the sleeve 34 with the annular guide groove 36 rotates along the annular guide bar 37, which can provide stable support and guidance, ensuring that the feed head 2 always maintains a stable position during the rotation process. Maintaining a stable state and avoiding unstable phenomena such as shaking or offset, the reliability of the entire equipment operation is greatly improved. The first balls 38 are regularly distributed. When the sleeve 34 rotates, the first balls 38 roll between the annular guide groove 36 and the annular guide bar 37. Compared with traditional sliding friction, this rolling friction method can greatly reduce the friction between the two. The reduction in friction makes the sleeve 34 smoother during rotation, and the required driving force is significantly reduced, thereby effectively reducing the energy consumption during equipment operation and saving costs for the enterprise.

[0041] In addition, it also includes a rotating connection member 5 connected to the inside of the end of the feed head 2, the rotating connection member 5 includes a connecting column 51 for connecting the coil spring, a movable column 52 is connected to the connecting column 51, a receiving groove 21 for accommodating the connecting column 51 is opened inside the end of the feed head 2, a movable groove 22 is opened inside the receiving groove 21, the movable column 52 rotates to match the movable groove 22, and a plurality of second balls 53 are installed on the outer circumference of the movable column 52. After the hose suction machine body 1 is started, the coil spring rotates in the hose, and the end of the coil spring rotates in the feed head 2 by relying on the connecting column 51 and the movable column 52 to avoid hindering the rotation of the feed head 2, wherein the movable column 52 is small on the outside and large on the inside, and is preferably formed by two sections of columns of different diameters fixedly connected. This arrangement can prevent the movable column 52 from disengaging from the movable groove 22 while ensuring the rotation of the coil spring. Secondly, the arranged second balls 53 are also used to reduce friction.

[0042] See also Figure 3 As shown, the rotating assembly 3 also includes a motor 32 installed outside the connecting hard tube 31, a driving gear 33 is installed at the output end of the motor 32, a passive gear ring 35 is fixed at the outer end of the sleeve 34, the driving gear 33 and the passive gear ring 35 are meshed and connected, and the motor 32 can be started to drive the driving gear 33 to rotate by the output end of the motor 32, and then drive the meshed passive gear ring 35 to rotate. The rotation of the feed head 2 can be realized, wherein the driving gear 33 and the passive gear ring 35 can be set to a suitable transmission ratio, such as 3:1, at this time, when the driving gear 33 rotates three times, the passive gear ring 35 rotates one circle, so as to ensure the appropriate rotation speed of the feed head 2.

[0043] The material guide assembly 6 also includes a first connecting rod 63 rotatably connected to the material receiving surface of the material receiving plate 4. The bottom end of the movable material guide plate 61 is fixed on the first connecting rod 63, and a return spring 62 is connected between the movable material guide plate 61 and the material receiving plate 4. When there are many biomass particles on the movable material guide plate 61, the return spring 62 is compressed. After the biomass particles fall, the return spring 62 can restore the movable material guide plate 61 to its original state to meet the next material receiving need.

[0044] Through the above, when it is used specifically, the staff will place the discharge end of the hose suction machine body 1 in the area to receive the biomass particles (if it is loaded into a truck for storage, it will be installed somewhere in the car), and place the feed head 2 above the biomass particle pile, and then the hose suction machine body 1 can be started, and the motor 32 can be started. While the spiral spring rotates to feed, the feed head 2 can rotate continuously. During the rotation of the feed head 2, the external material holding plate 4 rotates accordingly. When the material holding plate 4 rotates from bottom to top, the biomass particles can be placed on the material holding plate 4. As the rotation continues, the movable guide plate 61 first plays a blocking role. When the material holding plate 4 does not rotate to a certain height, it blocks the biomass particles from being loaded onto the material holding plate 4. The particles fall, reducing the feeding of biomass particles from the feed head 2. As the holding plate 4 continues to rotate, when it rotates to the point where the movable guide plate 61 bears the pressure of most of the biomass particles, the reset spring 62 will be squeezed and compressed quickly. The movable guide plate 61 deflects downward, and a large amount of biomass particles can fall from the upper area of ​​the feed head 2, increasing the amount of material received by the feed head 2 and improving the feeding efficiency. After the biomass particles fall from the movable guide plate 61, the movable guide plate 61 can be quickly reset under the action of the reset spring 62 to realize the subsequent feeding operation again. In this way, automatic and rapid feeding can be realized without the need to manually push the biomass particles to the top of the feed head end.

[0045] Among them, since the feed head 2 is initially placed at the upper end of the biomass particle pile, the feeding plate 4 continues to transport the biomass particles below it to the upper area for feeding, and the feed head 2 will gradually fall until the feed head 2 reaches the bottom surface of the biomass particle pile. In order to avoid the feed head 2 contacting the ground and causing damage to the feeding plate 4, etc., the staff can observe the position of the feed head 2 at intervals. When it is about to reach the ground, the staff can manually adjust the position of the feed head 2 so that it is back at the upper end of the biomass particle pile.

[0046] Example 2: Please refer to Figure 5-Figure 8 As shown, the present embodiment is extended on the basis of embodiment 1: the feeding device suitable for biomass particles also includes a follower knocking component 7, which is arranged on the first connecting rod 63. When the movable guide plate 61 deflects downward or returns to its original position after deflecting downward, the follower knocking component 7 can knock the material holding plate 4.

[0047] Among them, see Figure 7-Figure 8 As shown, the follower knocking assembly 7 includes a second knocking piece 74 fixed at both ends of the first connecting rod 63. When the return spring 62 is in a natural state, the knocking end of the second knocking piece 74 is in contact with the material receiving surface of the material receiving plate 4. When the movable material guide plate 61 returns to its original position from the downward deflected state, the second knocking piece 74 rotates synchronously with the first connecting rod 63, and can knock the material receiving plate 4 to prevent biomass particles with too high humidity from adhering to the material receiving plate 4.

[0048] See also Figure 5-Figure 8 As shown, the follower knocking assembly 7 also includes a second connecting rod 71 rotatably connected to the material receiving surface of the material receiving plate 4, the second connecting rod 71 is parallel to the first connecting rod 63, and a plurality of first knocking members 72 are equidistantly installed on the outside of the second connecting rod 71, when the reset spring 62 is in a natural state, there is a knocking distance between the knocking end of the first knocking member 72 and the material receiving surface of the material receiving plate 4, and a gear connecting member 73 is connected between the second connecting rod 71 and the first connecting rod 63, and the opposite rotation of the movable material guide plate 61 and the first knocking member 72 is realized through the gear connecting member 73, wherein the gear connecting member 73 includes a first gear 731 installed on the first connecting rod 63 and a second gear 732 installed on the second connecting rod 71, and the first gear 731 and the second gear 732 are meshingly connected.

[0049] Through the above, during specific use, when the movable material guide plate 61 rotates to a certain height and is pressed and deflected downward, at this time, the first connecting rod 63 rotates to drive the first gear 731 thereon to rotate, and the first gear 731 will drive the meshing second gear 732 to rotate, so that the second connecting rod 71 rotates in the opposite direction, and then the multiple first knocking members 72 knock the material holding plate 4, so that the biomass particles with too high humidity are separated from the material holding plate 4, and when the movable material guide plate 61 returns to its original position, the first knocking member 72 returns to its original position, and at the same time knocks the material holding plate 4 through the second knocking member 74.

[0050] Among them, during the process of the first knocking member 72 performing the knocking action, its function is not limited to simple knocking. In fact, the first knocking member 72 can also rely on its own structural characteristics and movement trajectory to effectively move the biomass particles that are about to fall. By moving, the original static or aggregated state of the biomass particles is broken, making the arrangement and distribution of the biomass particles looser and more uniform, thereby effectively reducing the probability of biomass particles being blocked between the movable guide plate 61 and the material holding plate 4, ensuring that the entire biomass particle conveying process can run stably and efficiently.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
