Description

Technical Field

[0001] This utility model relates to the technical field of vertical pellet mill components, and more specifically, to a scraping mechanism for a vertical pellet mill. Background Technology

[0002] Vertical pellet mills are effective equipment for producing biomass combustion pellets. They are production machines that process biomass as raw material into pellet biomass fuel.

[0003] Currently, the scraping mechanism of commonly used vertical pellet mills has a small cutting area with the material during use, which reduces cutting efficiency. Moreover, it may cause shaking when connected to a main shaft with different outer diameters. For example, CN222093256U discloses a scraping mechanism for a vertical ring die pellet mill, which includes a scraper; a throwing arm, which is set on the outer side of the scraper; a throwing disc, which is set on the lower end face of the throwing arm and fixedly connected to the throwing arm; and a cutting blade, which is set on the upper end face of the throwing disc. The scraper has a cylindrical structure with a fixing plate on the inner side, which is installed on the main shaft of the pellet mill. The throwing arm is L-shaped and is connected to the outer side of the scraper and the upper end face of the throwing disc by welding. The throwing disc is set below the scraper. The cutting blade has a plate-like structure, which forms an acute angle with the central axis of the throwing disc and is vertically set.

[0004] As can be seen from the above-disclosed scheme, the scraping mechanism only cuts the material by rotating the cutting blade during use. The cutting blade contacts very little material, which greatly reduces the cutting efficiency. At the same time, when the scraper is connected to the main shaft of the vertical ring die pellet mill through the fixed plate, the outer diameter of the main shaft of different models may be different, which leads to a mismatch between the size of the main shaft and the internal hole of the scraper. This makes it easy for the main shaft to shake with the scraper during rotation, reducing the stability of use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a scraping material mechanism for a vertical pellet mill. This scraping material mechanism for a vertical pellet mill, through the arrangement of blades, a scraping plate, a support shaft, and a disc cutter, can increase the cutting area with the material during the rotational scraping process, thereby greatly improving the cutting efficiency. Furthermore, through the arrangement of a fixing plate and elastic elements, it not only facilitates the connection of the mounting sleeve with main shafts of different outer diameters, but also prevents the main shaft from shaking inside the mounting sleeve, thus improving the stability of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A scraping and feeding mechanism for a vertical pellet mill includes a scraping and feeding mechanism body, which includes a feeding disc. Feeding components are arranged on the surface of the feeding disc, and these components are distributed in a ring at equal intervals around the center of the feeding disc. A connecting rod is fixedly connected to the surface of the feeding disc, and a connecting component is fixedly connected to one end of the connecting rod. The connecting component includes a mounting sleeve, one end of which is fastened to the main shaft of the vertical pellet mill via a screw. This scraping and feeding mechanism for a vertical pellet mill, through the arrangement of blades, feeding plates, support shafts, and disc cutters, can increase the cutting area with the material during rotational feeding, thereby greatly improving cutting efficiency. Furthermore, the fixed plate and elastic elements not only facilitate the connection of the mounting sleeve with main shafts of different outer diameters but also prevent the main shaft from shaking inside the mounting sleeve, improving operational stability.

[0008] Furthermore, the material feeding assembly includes a material feeding plate with a through hole on its surface. A support shaft is fixedly installed on the inner wall of the through hole, and a disc cutter is rotatably connected to the surface of the support shaft. The disc cutter can be squeezed and rotated to cut the material after contacting it, thereby increasing the cutting efficiency.

[0009] Furthermore, the connecting angled rod is inclined and is distributed in a ring with equal spacing around the center of the material throwing disc. A blade is fixedly connected to the advancing surface of the connecting angled rod, and the blade can contact and cut the material when rotating, thus improving the cutting efficiency.

[0010] Furthermore, one end of the mounting sleeve has a sleeve hole, and an elastic element is fixedly connected to the inner wall of the sleeve hole. The surface of the elastic element is movably connected to the surface of the vertical pellet mill spindle. When the elastic element is squeezed, it can automatically adjust the clamping distance, thereby clamping spindles of different outer diameters and increasing its connection stability.

[0011] Furthermore, the elastic element is made of elastic stainless steel, the surface of the elastic element is provided with a clamping surface, and both ends of the elastic element are provided with bending portions, so that the elastic element has the function of compressive elastic force.

[0012] Furthermore, a fixing plate is fixedly connected to one end of the mounting sleeve. The surface of the fixing plate has a central hole and a connecting hole, which facilitate the fixing plate to be fastened to the spindle by a single screw or a double screw.

[0013] Furthermore, the inner wall of the through hole is provided with a positioning groove, and the end face of the positioning groove is detachably connected to the end face of the support shaft, which facilitates the disassembly and replacement of the disc cutter in the later stage.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can increase the cutting area with the material during the rotation feeding process by setting up the blade, feeding plate, support shaft and disc cutter, thereby greatly improving the cutting efficiency.

[0016] (2) This solution, through the setting of the fixed plate and elastic element, not only facilitates the connection between the mounting sleeve and spindles with different outer diameters, but also prevents the spindle from shaking inside the mounting sleeve, thus improving the stability of use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5A scraping mechanism for a vertical pellet mill, specifically a vertical ring die pellet mill, is disclosed. Its structure and working principle are well-known to those skilled in the art. The mechanism includes a scraping mechanism body 1, which discharges material from the pellet mill. The scraping mechanism body 1 is driven to rotate by the pellet mill's main shaft, eliminating the need for a separate motor, thus reducing energy consumption and saving costs. The scraping mechanism body 1 includes a throwing disc 2, with a feeding assembly 3 on its surface. The feeding assembly 3 can feed and cut material during rotation. The feeding assembly 3 includes a feeding plate 31, with a through hole 32 on its surface. A support shaft 34 is fixedly installed on the inner wall of the through hole 32. The surface of the support shaft 34 rotates... The device is equipped with a disc cutter 35, which can be squeezed and rotated to cut the material after contact with it. The large number of disc cutters 35 increases the cutting efficiency. The feeding assembly 3 is distributed in a ring with equal spacing around the center of the feeding disc 2. The surface of the feeding disc 2 is fixedly connected with a connecting inclined rod 6, which is inclined and distributed in a ring with equal spacing around the center of the feeding disc 2. The forward face of the connecting inclined rod 6 is fixedly connected with a blade 61, which can contact and cut the material when rotating, thus improving the cutting efficiency. One end of the connecting inclined rod 6 is fixedly connected with a connecting assembly 4, which includes a mounting sleeve 41. One end of the mounting sleeve 41 is fastened to the main shaft of the vertical pellet mill by a screw.

[0027] One end of the mounting sleeve 41 has a sleeve hole 42, and an elastic element 5 is fixedly connected to the inner wall of the sleeve hole 42. The surface of the elastic element 5 is movably connected to the surface of the vertical pellet mill main shaft. When the elastic element 5 is squeezed, it can automatically adjust the clamping distance, thereby clamping the main shaft with different outer diameters and increasing its connection stability. The elastic element 5 is made of elastic stainless steel. The surface of the elastic element 5 is provided with a clamping surface 51. Both ends of the elastic element 5 are provided with bending parts 52. The elastic element 5 has the function of compressive elastic force.

[0028] One end of the mounting sleeve 41 is fixedly connected to a fixing plate 43. The surface of the fixing plate 43 has a center hole 44 and a connecting hole 45. The center hole 44 and the connecting hole 45 facilitate the fixing plate 43 to be fastened to the spindle by a single screw or a double screw. The inner wall of the through hole 32 has a positioning groove 33. The end face of the positioning groove 33 is detachably connected to the end face of the support shaft 34, which facilitates the disassembly and replacement of the disc cutter 35 later.

[0029] When the scraping and feeding mechanism for the vertical pellet mill is connected to the main shaft of the pellet mill, one end of the main shaft can be inserted downward into the sleeve hole 42, which will simultaneously compress the clamping surface 51 of the elastic element 5. At this time, the elastic element 5 generates a compressive force, which pre-positions the installation position of the main shaft. Then, one end of the main shaft is fastened to the fixing plate 43 by a screw. When the main shaft rotates, it drives the scraping and feeding mechanism body 1 to rotate, which in turn drives the blade 61 to rotate and cut the raw material. At the same time, it drives the feeding plate 31 to rotate and feed the material. The rotation of the feeding plate 31 makes the material contact and cut with the disc cutter 35. Through the blade 61, feeding plate 31, support shaft 34 and disc cutter 35, the cutting area with the material can be increased during the rotation feeding process, thereby greatly improving the cutting efficiency. Furthermore, through the fixing plate 43 and elastic element 5, it is not only convenient to connect the mounting sleeve 41 with main shafts of different outer diameters, but also prevents the main shaft from shaking inside the mounting sleeve 41, thus improving the stability of use.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
