Description

Technical Field

[0001] This utility model relates to the technical field of biomass fuel processing equipment, and in particular to a baling machine that can be connected to a boiler combustion chamber. Background Technology

[0002] Biomass fuels, such as crop straw, typically require compression before entering the boiler combustion chamber to improve combustion efficiency and calorific value. Current methods often employ hydraulic balers to compress biomass fuels like straw before sending them into the combustion chamber. This method is widely used in the pre-treatment of biomass fuels; its basic principle is to use a hydraulic baler to compress loose biomass fuel under high pressure, reducing its volume and increasing its density, thus facilitating transportation and combustion. However, the existing process involves intermediate steps, leading to increased consumption of manpower and resources, and raising production costs.

[0003] In existing technologies, after crop straw is compressed, it needs to be transported to the boiler combustion chamber manually or mechanically. The workflow is as follows: a hydraulic cylinder compresses the straw into blocks, and the compressed material is discharged from the outlet. Subsequently, additional conveying equipment or manual labor is required to transfer the material to the combustion chamber. In this case, the compression chamber and the combustion chamber are independent systems, and there is no direct connection between the outlet and the combustion chamber.

[0004] Therefore, the compressed fuel packs need to be handled twice, increasing labor costs and equipment investment. If they are directly connected through pipelines, the material transport process from the hydraulic baler to the boiler combustion chamber is not smooth enough, which can easily lead to material blockage and affect overall production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model embodiment is to provide a baler that can be connected to a boiler combustion chamber.

[0013] Optionally, the material guiding mechanism further includes a fireproof door, which is located at the tail end of the material guiding pipe and is used to isolate the material guiding pipe from the combustion chamber.

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] like Figure 1 As shown, this embodiment proposes a packing machine that can be connected to a boiler combustion chamber, including a compression mechanism 2 and a material guiding mechanism 1, wherein the material guiding mechanism 1 is installed between the compression mechanism 2 and the combustion chamber; as shown Figure 2 , Figure 3 , Figure 4 As shown, the material guiding mechanism 1 includes a material guiding pipe 11, a variable cross-section plate 14, and a driving assembly 12. One end of the material guiding pipe 11 is connected to the discharge port of the compression mechanism 2, and the other end is connected to the combustion chamber. The material guiding pipe 11 has a fixed cross-section section 111 and a variable cross-section section 113. The variable cross-section plate 14 is installed on the variable cross-section section 113, and the front end of the variable cross-section plate 14 is rotatably connected to the fixed cross-section section 111 of the material guiding pipe 11. The driving assembly 12 is installed on the variable cross-section section 113 to drive the variable cross-section plate 14 to rotate.

[0030] This baler incorporates a material guiding mechanism 1, installed between the compression mechanism 2 and the combustion chamber. This allows for direct material transport to the combustion chamber after compression, eliminating intermediate transfer links and reducing production costs. The material guiding mechanism 1 has a guide pipe 11 connected at one end to the outlet of the compression mechanism 2 and at the other end to the combustion chamber. The guide pipe 11 has a fixed cross-section section 111 and a variable cross-section section 113. A variable cross-section plate 14 is installed in the variable cross-section section 113. The variable cross-section plate 14 is driven to rotate by a drive assembly 12, effectively preventing material from jamming within the guide pipe 11 and ensuring smooth material transport.

[0031] The fixed cross-section section of the feed tube 11 is a square tube, and the variable cross-section section 113 has a base plate. The base plate is connected to the bottom surface of the square tube, and a variable cross-section space is formed on the upper side of the base plate.

[0032] The fixed cross-section section 111 of the feed guide pipe 11 adopts a square tube structure, which gives the feed guide pipe 11 good strength and stability. The variable cross-section section 113 is equipped with a base plate and connected to the bottom surface of the square tube. The upper part of the base plate forms a variable cross-section space. This structural design provides a spatial basis for changing the cross-section size through the variable cross-section plate 14, which facilitates the function of flexibly adjusting the cross-section according to the material ejection situation, so as to adapt to the conveying needs of different materials and improve the applicability and reliability of the equipment.

[0033] The variable cross-section plate 14 has three pieces, which are located on the left, right and top sides of the bottom plate, respectively, and are rotatably connected to the three pipe walls of the fixed cross-section section 111 of the guide pipe 11. The bottom plate of the guide pipe 11 and the three variable cross-section plates 14 form a variable cross-section space.

[0034] Three variable cross-section plates 14 are located on the left, right, and top sides of the upper part of the base plate, and are rotatably connected to the three pipe walls of the fixed cross-section section 111 of the guide pipe 11, forming a variable cross-section space together with the base plate. This design of three variable cross-section plates 14 allows for flexible adjustment of the variable cross-section space from multiple directions. When the material is loose, the cross-section can be reduced; when the pushing resistance increases and it is difficult to push out, the cross-section can be increased, making it easier to push out the material. This effectively solves the problem of poor material conveying in the guide pipe 11 and improves the efficiency and stability of material conveying.

[0035] The fixed section 111 of the feed pipe 11 is equipped with a rotating shaft, and the end of the variable cross-section plate 14 is equipped with an ear seat, which is rotatably mounted on the rotating shaft. A through-type rotating shaft is provided on the end wall of the fixed section, and an ear seat with a shaft hole is welded to the end of the variable cross-section plate 14, forming a rotating pair with the rotating shaft through a bearing. This connection method is simple and reliable, facilitating the rotation of the variable cross-section plate 14, thereby flexibly adjusting the size of the variable cross-section space, ensuring that the variable cross-section plate 14 can rotate stably and smoothly during operation, guaranteeing the normal operation of the equipment and the smooth conveying of materials.

[0036] A connecting frame 112 is provided on the feed tube 11. The connecting frame 112 includes a horizontal plate and a vertical plate. The horizontal plate is arranged along the axial direction of the feed tube 11 and spans the variable cross-section section 113. The vertical plate is perpendicular to the axial direction of the feed tube 11. The lower side of the vertical plate is connected to the bottom plate, and the upper side of the vertical plate is connected to the horizontal plate.

[0037] The connecting frame 112 adopts a three-dimensional frame structure. The horizontal plate extends along the axis of the guide pipe 11 to form the main load-bearing beam, and the longitudinal plate vertically connects the horizontal plate and the bottom plate to form a support. This design effectively transfers the dynamic load of the variable cross-section section 113 to the fixed section, ensuring the stability and reliability of the equipment during operation and helping to improve the service life of the equipment.

[0038] like Figure 3 , Figure 4 As shown, the drive assembly 12 includes a variable cross-section drive cylinder 121 and a linkage mechanism 122. The linkage mechanism 122 includes an L-bar, a diagonal bar, and a cross bar that are hinged in sequence. The lower end of the L-bar is hinged to the base plate. One end of the variable cross-section drive cylinder 121 is connected to the cross bar, and the other end abuts against the variable cross-section plate 14.

[0039] When the hydraulic cylinder extends, the linkage of the horizontal bar, the diagonal bar, and the L-bar enables precise control of the size of the variable cross-section space, ensuring smooth material transport within the guide pipe 11. This structural design also features high transmission efficiency and stability, which helps improve the operating performance of the equipment.

[0040] like Figure 2 As shown, the material guiding mechanism 1 also includes a fireproof door 13, which is located at the tail end of the material guiding pipe 11 and is used to isolate the material guiding pipe 11 from the combustion chamber. Since the combustion process inside the combustion chamber may generate high temperatures and flames, the fireproof door 13 effectively prevents backfire, avoids flames from entering the baling machine through the material guiding pipe 11, and prevents threats to the normal operation of the baling machine and the safety of the operators. It also protects other components of the equipment from damage by high-temperature flames, improving the safety and reliability of the equipment.

[0041] like Figure 5 As shown, the fire door 13 includes a fireproof drive cylinder 132 and a fireproof plate 131, and a fireproof seat 114 is provided at the tail end of the guide pipe 11 (e.g., Figure 3 As shown, the fireproof plate 131 is inserted into the fireproof seat 114. The fireproof plate 131 is provided with a material conveying port. The fireproof drive cylinder 132 is installed on both sides of the fireproof seat 114. The fireproof drive cylinder 132 is used to drive the fireproof plate 131 to rise and fall so that the material conveying port is aligned or misaligned with the guide pipe 11.

[0042] During material discharge, the fireproof drive cylinder 132 drives the fireproof plate 131 to descend, aligning the material inlet with the guide pipe 11, allowing the material to smoothly enter the combustion chamber. During non-discharge, the fireproof plate 131 rises, misaligning the material inlet with the guide pipe 11, thereby effectively isolating the guide pipe 11 from the combustion chamber and preventing backfire. This design ensures normal material transport while achieving reliable fire prevention, thus improving the safety and stability of the equipment.

[0043] like Figure 6 As shown, the compression mechanism 2 includes a feeding bin 21, a first compression bin 25, and a second compression bin 24. The feeding bin 21 is located at the top and is used to receive the material to be compressed. The first compression bin 25 is located below the feeding bin 21 and is connected to the feeding bin 21. The material enters the first compression bin 25 from the feeding bin 21. The second compression bin 24 is located at the end of the first compression bin 25 and is connected to the first compression bin 25. Through this structural design, the material can pass through the feeding bin 21, the first compression bin 25, and the second compression bin 24 in sequence for orderly compression processing, providing a good foundation for subsequent material conveying and combustion. At the same time, the interconnected design between the bins makes the material transmission smoother, improving the overall working efficiency and compression effect of the baler.

[0044] The first compression chamber 25 is equipped with a first compression mechanism 22 for preliminary compression of materials. The second compression chamber 24 is equipped with a second compression mechanism 26. The block ejection mechanism is equipped with an ejection component 23. The ejection component 23 is collinear with the material guiding mechanism 1. The first compression mechanism 22, the second compression mechanism 26 and the ejection component 23 are perpendicular to each other.

[0045] This layout design allows the material to be initially compressed in the first compression chamber 25, and then further compressed by the second compression mechanism 26. After compression, since the ejection component 23 and the material guiding mechanism 1 are collinear, the compressed material can directly enter the material guiding pipe 11 and be transported to the combustion chamber. The mutually perpendicular mechanism layout makes the entire compression process more reasonable and efficient, improves the compression quality of the material and the overall working efficiency of the equipment, and also contributes to the structural compactness and stability of the equipment.

[0046] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
