[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Loose materials are widely present in production and daily life, and their transportation and storage are inconvenient. In order to facilitate storage and transportation and reduce storage and transportation costs, these loose materials are briquetized into small rectangular blocks, which can be easily stacked, thereby achieving the purpose of facilitating storage and transportation and correspondingly reducing storage and transportation costs.

[0004] Existing briquetting devices typically employ a two-step compression method: horizontal and vertical compression. Loose material enters the hopper, is first compressed horizontally, and then vertically after reaching a certain compression level. This type of briquetting device suffers from low efficiency. Furthermore, after the briquettes are removed, the expansion rates in different directions are inconsistent, resulting in irregular briquette shapes that are unfavorable for transportation, storage, and subsequent coating processes. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a briquetting device to improve production efficiency, ensure that the briquetting blocks have a regular shape, and facilitate transportation, storage and coating.

[0008] Preferably, the first pressure head assembly and the second pressure head assembly have the same structure. The second pressure head assembly includes a pressure head body and a compression cylinder. The pressure head body is provided with a connecting seat for mounting the compression cylinder. The compression cylinder drives the pressure head body to squeeze the material.

[0009] Preferably, a movable cutter is provided on the front side of the pressure head body along the compression direction, and a fixed cutter is provided at the bottom of the feed hopper, with the fixed cutter located on the moving trajectory of the movable cutter.

[0010] Preferably, the moving cutter is detachably mounted on the pressure head body, and an adjustment shim is provided between the moving cutter and the pressure head body.

[0011] Preferably, the connecting seat has a ring-shaped structure, and a reinforcing plate is provided on the outer periphery of the connecting seat.

[0012] Preferably, the first pressure head assembly is at a 45-degree angle to the horizontal plane, and the second pressure head assembly is at a 45-degree angle to the horizontal plane.

[0013] Preferably, the compression chamber is further provided with a pushing component for pushing the pressure block, the moving direction of the pushing component is perpendicular to the moving direction of the pressure head component, and a bag outlet is provided on the side of the compression chamber opposite to the pushing component.

[0017] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0018] This invention features two pressure head assemblies positioned vertically and at an angle on either side of the compression chamber. During briquetting, both pressure head assemblies simultaneously compress loose material, significantly improving production efficiency compared to the sequential compression methods of existing briquetting devices. Furthermore, because both pressure head assemblies press the material downwards at an angle during compression, the compressed material fills the entire compression chamber relatively evenly. This results in briquettes with a consistent density, and even if they rebound after removal, the rebound is generally uniform across all locations. Compared to existing compression methods, the briquettes produced by this device have a more regular shape, facilitating transportation, storage, and subsequent coating processes.

[0019] Advantages of additional aspects of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the 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.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is intended to include the plural form as well. 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.

[0034] For ease of description, the terms "front," "rear," "left," "right," "up," and "down" appearing in this invention only indicate that they correspond to the front, rear, left, right, up, and down directions of the accompanying drawings themselves. They do not limit the structure and are merely for the convenience of describing the invention and simplifying the description, not to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0035] As described in the background section, existing briquetting devices employ a two-step compression method involving horizontal and vertical movements, which is inefficient. The briquetting process is as follows: Figure 1 As shown, the horizontal pressure head compresses first. When the straw is compressed to the same width as the vertical pressure head, the vertical pressure head begins to compress until the set amount is reached, completing the briquetting process. That is, the compression in the two directions has a sequential order. If the two briquettes compress simultaneously, the following will occur: Figure 2 The shape of the briquetting block shown is unsuitable for briquetting. Therefore, this type of briquetting device in the prior art cannot perform compression simultaneously, resulting in low work efficiency.

[0036] On the other hand, existing briquetting devices are all horizontally placed with the loading hopper opening facing upwards and a flat bottom. The material being compressed is loose and not homogeneous, often denser at the bottom and looser at the top. After compression, the density is inconsistent. Before removal, the briquette cross-section is square; after removal, it springs back, and due to the inconsistent density, the springback size is also inconsistent, resulting in irregular shapes. For example, the cross-section may become trapezoidal or other irregular shapes. These irregularly shaped straw briquettes are inconvenient to arrange during storage and transportation, wasting space and causing overall instability. Furthermore, when these irregularly shaped briquettes are subsequently wrapped, some areas are tightly wrapped while others are loosely wrapped, making the wrapping process difficult.

[0037] To address the aforementioned technical problems, this invention proposes a briquetting device for briquetting materials such as corn stalks, corn cobs, peanut vines, and wheat straw. Figures 3-7 As shown, it includes: a frame 1 and a pressure head assembly; the frame 1 has a compression chamber 12 for containing materials, and the compression chamber 12 is provided with a feed hopper 11 for filling; the pressure head assembly is used to compress the materials, and includes a first pressure head assembly 3 and a second pressure head assembly 6, the first pressure head assembly 3 and the second pressure head assembly 6 are disposed on both sides of the compression chamber 12, the first pressure head assembly 3 and the second pressure head assembly 6 are inclined, and the second pressure head assembly 6 is perpendicular to the first pressure head assembly 3.

[0038] Furthermore, such as Figure 1 , Figure 5 As shown, the compression chamber 12 is also provided with a pushing component 4 for pushing the pressing block. The moving direction of the pushing component 4 is perpendicular to the moving direction of the pressing head component. The side of the compression chamber 12 opposite to the pushing component 4 is provided with a bag outlet 2.

[0039] like Figure 3 As shown, the frame 1 is assembled from steel plates and shaped steel by welding. A feeding hopper 11 is located at the top of the frame 1, and a straw compression chamber 12 is positioned at the center of the frame 1. The upper feeding hopper 11 is connected to the compression chamber 12. A square cavity is located on each of the left and right sides of the compression chamber 12, serving as a guide for the forward and backward movement of the pressing head assembly. A square cavity is located on the rear side of the compression chamber 12, serving as a guide for the forward and backward movement of the pressing assembly 4. An openable and closable door is located on the front side of the compression chamber 12, and a bale outlet 2 is located on the outer side of the door. An automatic wrapping device can be installed on the outer side of the bale outlet 2.

[0040] This invention features two pressure head assemblies on both sides of the compression chamber 12. These assemblies are vertically and inclined, allowing for simultaneous compression of materials such as straw during briquetting. This significantly improves production efficiency compared to the sequential compression methods of existing briquetting devices. Furthermore, because both pressure head assemblies are inclined downwards during compression, the compressed material fills the entire compression chamber 12 relatively evenly. This results in briquettes with a consistent density, and even after rebound, the rebound is uniform across all locations. Compared to existing compression methods, the briquettes produced by this device have a more regular shape, facilitating transportation, storage, and subsequent coating.

[0041] In this embodiment, the first pressure head assembly 3 is at a 45-degree angle to the horizontal plane, and the second pressure head assembly 6 is at a 45-degree angle to the horizontal plane. The first pressure head assembly 3 and the second pressure head assembly 6 are symmetrically arranged on both sides of the compression chamber 12.

[0042] The first pressure head assembly 3 and the second pressure head assembly 6 have the same structure, such as Figure 7As shown, the second pressure head assembly 6 includes a pressure head body 621 and a compression cylinder 61. The pressure head body 621 is provided with a connecting seat 624 for mounting the compression cylinder 61. The compression cylinder 61 drives the pressure head body 621 to compress the material. The connecting seat 624 has an annular structure, and a reinforcing plate 625 is provided on the outer periphery of the connecting seat 624 to ensure the installation strength of the connecting seat 624.

[0043] An inclined pressure head assembly, driven by a compression cylinder 61, is installed in each of the square cavities on the left and right sides of the compression chamber 12. The compression cylinder 61 is installed outside the square cavity. An extrusion head 62, driven by a push-bag cylinder 41, is installed in the square cavity on the rear side of the compression chamber 12. A push-bag cylinder 41 is installed outside the square cavity. An openable and closable door is located on the opposite side, with a bag outlet 2 on the outer side of the door. Both the compression cylinder 61 and the push-bag cylinder 41 are hydraulic cylinders.

[0044] like Figure 4 , Figure 7 As shown, a movable cutter 623 is provided on the front side of the pressure head body 621 along the compression direction, and a fixed cutter 7 is provided at the bottom of the feed hopper 11. The fixed cutter 7 is located on the moving trajectory of the movable cutter 623. Under the drive of the compression cylinder 61, the pressure head assembly moves obliquely downward to compress the material. When the movable cutter 623 of the pressure head assembly comes into contact with the fixed cutter 7, it will generate shearing on the material, cutting the material below into shape while compressing.

[0045] The structure of the pressing assembly 4 is similar to that of the pressing head assembly, except that it does not have the moving cutter 623. The pressing assembly 4 can be replaced by the pressing head assembly. The pushing cylinder 41 is connected to the pressing head 42, which drives the pressing head 42 to move back and forth. After the pressing block is completed, the pressing block is pushed out.

[0046] like Figure 7 As shown, the movable cutter 623 is detachably mounted on the pressure head body 621. An adjusting shim 622 is provided between the movable cutter 623 and the pressure head body 621. The position of the movable cutter 623 can be adjusted by changing the thickness of the adjusting shim 622.

[0047] like Figure 3 , Figure 6As shown, a stirrer 5 is installed inside the frame 1. The stirrer 5 is located below the feed hopper 11. The stirrer 5 includes a rotating shaft, with both ends of the shaft rotatably connected to the frame 1. Stirring blades are installed on the rotating shaft. There are two stirrers 5, located on both sides of the center of the feed hopper 11. Multiple stirring blades are arranged axially on the rotating shaft, and the stirring blades are inclined at a predetermined angle to the rotating shaft. A detachable stirrer 5 is installed inside the feed hopper 11. The stirrer 5 is driven to rotate by a hydraulic motor. The stirrer 5 disperses the material in the middle part to the four corners, especially for materials with poor flowability. The oblique extrusion of the two pressing head assemblies, combined with the dispersion treatment of the stirrer 5, makes the density of the compressed block more uniform and ensures the regularity of the block shape.

[0048] Based on the above-mentioned briquetting device, the present invention also proposes a briquetting and wrapping integrated machine, wherein the briquetting device has a bag outlet 2, and an automatic wrapping device is provided at the bag outlet 2.

[0049] Working principle as follows Figure 8 As shown: Before feeding, the door on the front side of the compression chamber 12 is closed. After feeding into the hopper 11, the two inclined pressure head assemblies move forward under the drive of the hydraulic cylinder to compress the material in the compression chamber 12. After being compressed into a square shape, the push pressure head 42 pushes the block out of the compression chamber 12 under the action of the push-bag cylinder 41. During the pushing process, the automatic wrapping device performs axial wrapping on the compressed block. Afterward, the receiving unit of the automatic wrapping device transfers the compressed block to the idler roller of the automatic wrapping device for radial wrapping, completing all the work.

[0050] This invention uses two symmetrically arranged hydraulic cylinders to compress materials such as straw at the same time. The compressed material can fill the entire compression chamber 12 relatively evenly. During the compression process, when the moving cutter 623 moves to the position of the fixed cutter 7, the material at the interface will be cut off. In this way, the compressed block has a basically uniform density and a basically uniform rebound after being taken out. Therefore, the shape of the compressed block is relatively regular.

[0051] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. 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 solutions of the present invention are still within the scope of protection of the present invention.
