Description

Technical Field

[0001] This utility model relates to the field of biomass firewood processing, and in particular to a disc-type irregular biomass firewood crushing device. Background Technology

[0002] Biomass fuel, as a renewable energy source, has broad application prospects in the energy sector. However, irregularly shaped biomass fuel (such as branches and straw) presents numerous challenges to subsequent processing and utilization due to their varied forms and sizes. Currently, existing crushing devices on the market suffer from low crushing efficiency, unsatisfactory crushing effects, and easy equipment damage when processing irregular biomass fuel. For example, some traditional crushers use hammer or blade crushing structures, which tend to cause rapid wear of the hammers or blades and insufficient crushing when processing coarser or harder biomass fuel. Furthermore, some crushing devices have unreasonable designs in terms of feeding and discharging, easily leading to material blockage and affecting the normal operation of the equipment. Therefore, disc crushing devices have emerged. However, these devices experience significant wear, requiring periodic replacement of the grinding disc over time. Replacing the grinding disc in existing devices requires disassembling many fixed structures, resulting in high maintenance difficulty. Moreover, existing devices require manual feeding, leading to low feeding efficiency and thus reducing the overall processing efficiency. Utility Model Content

[0025] 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.

[0026] like Figures 1-7 As shown, a disc-type irregular biomass firewood crushing device includes a crushing component 1 and a feeding component 2 that are detachably connected. The crushing component 1 includes a shell part and a grinding part. The grinding part is disposed inside the shell part, and a conveying channel for conveying raw materials is formed on the feeding component 2. The conveying channel is connected to the inside of the shell part. The crushing component 1 includes a second grinding disc 16 and a first grinding disc 15.

[0027] The second grinding disc 16 is located above the first grinding disc 15, and a through-hole 18 is vertically opened on the second grinding disc 16. Multiple limiting rods 13 are fixedly connected in a ring array on the inner wall of the housing part. A discharge hole 14 is opened on the housing part. Multiple limiting grooves 19 are formed by the indentation of the outer wall of the second grinding disc 16 in a ring array. The limiting grooves 19 are matched with the limiting rods 13 one by one. A rotating shaft 112 is rotatably connected to the bottom of the housing part. The top of the rotating shaft 112 is open to form a cross groove 113. A cross rod 110 matching the cross groove 113 is fixedly connected to the bottom of the first grinding disc 15.

[0028] According to the above technical solution, before crushing the raw materials, the first grinding disc 15 is placed inside the housing, and the cross bar 110 at the bottom of the first grinding disc 15 is inserted into the cross groove 113 on the rotating shaft 112, thus completing the installation of the first grinding disc 15. Then, the second grinding disc 16 is placed inside the housing, and the limiting rod 13 inside the housing engages with the limiting groove 19 on the second grinding disc 16, thus completing the installation of the second grinding disc 16. After the second grinding disc 16 is installed, the feed component 2 is connected to the housing. After the device is installed, the raw materials to be crushed are fed into the feed component 2. The feed component 2 guides the raw materials into the housing. Then, through the guide hole 18 on the second grinding disc 16, the raw material enters between the first grinding disc 15 and the second grinding disc 16. The first grinding disc 15 is rotated by the rotating shaft 112, thereby crushing the raw material. After crushing, the raw material is discharged through the discharge hole 14, completing the crushing of the raw material. When it is necessary to replace the first grinding disc 15 and the second grinding disc 16, the device is stopped, the crushing part 1 and the feeding part 2 are separated, and then the second grinding disc 16 is pulled to move the second grinding disc 16 to the outside of the housing part. Then the first grinding disc 15 is pulled to separate the cross rod 110 from the cross groove 113, so that the first grinding disc 15 can be disassembled, making it easy to replace the first grinding disc 15 and the second grinding disc 16, thus improving the efficiency of device inspection and maintenance.

[0029] Specifically, in one embodiment, regarding the aforementioned feeder 2, as... Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the feeding component 2 includes a feeding hood 22, the peripheral surface of which is open to form a feeding groove 25, and a connecting pipe 24 is fixedly connected to the bottom of the feeding hood 22, and the connecting pipe 24 is screwed to the top of the housing part.

[0030] In this embodiment, the feed hood 22 is screwed to the shell part through the connecting pipe 24 to complete the installation of the feed hood 22. When raw materials need to be added, the raw materials are put into the feed trough 25 and the feed hood 22 guides the raw materials to be transported into the shell part. After the raw materials enter the shell part, the subsequent crushing process can be carried out.

[0031] Furthermore, in this invention, in order to improve the efficiency of raw material entering the device, such as... Figure 2 , Figure 6 and Figure 7 As shown, an auger 26 is rotatably connected inside the feed hood 22 along an axis perpendicular to the horizontal plane, and a conical cover 21 is fixedly connected to the top of the feed hood 22. A second motor 23 with two output ends is fixedly connected inside the conical cover 21, and one of the output ends of the second motor 23 is connected to the auger 26.

[0032] In this embodiment, after the raw material is added into the feed hood 22, the second motor 23 operates, thereby driving the auger 26 to rotate, so that the auger 26 drives the raw material to move along the feed hood 22, allowing the raw material to be transported into the housing part more quickly and improving the raw material feeding efficiency.

[0033] To make it easier to add ingredients, such as Figure 1 As shown, a guide cover 3 is fixedly connected to the circumferential surface of the feed cover 22, and the bottom of the guide cover 3 is located below the feed trough 25.

[0034] In this embodiment, when adding raw materials, the material guide cover 3 is used to facilitate the addition of raw materials without needing to align it with the feed trough 25, thus reducing the difficulty of adding raw materials.

[0035] After the raw material is added to the guide cover 3, in order to prevent the raw material from sticking to the guide cover 3, such as Figure 1 As shown, the other output end of the second motor 23 is fixedly connected to a scraper 4 for scraping the inner wall of the guide cover 3.

[0036] In this embodiment, when the raw material is added to the guide cover 3, the scraper 4 is driven to rotate through the other output end of the second motor 23, so that the scraper 4 pushes the raw material in the guide cover 3, allowing the raw material to be added faster and avoiding the raw material from sticking.

[0037] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-4 As shown, the housing includes a bottom shell 11, with a foot 12 fixedly connected to the bottom of the bottom shell 11, and a first motor 111 fixedly connected to the bottom of the bottom shell 11. The output end of the first motor 111 is connected to the rotating shaft 112, and a discharge hole 14 is opened on the circumferential surface of the bottom shell 11.

[0038] In this embodiment, the first motor 111 is supported by the bottom shell 11, and the first motor 111 drives the rotating shaft 112 to rotate, which in turn drives the first grinding disc 15 to rotate, thereby grinding and crushing the raw materials.

[0039] After the raw material is fed into the second grinding disc 16, in order to facilitate the feeding of the raw material into the guide hole 18, such as... Figure 3 As shown, the interior of the second grinding disc 16 is inclined to form a guide slope 17, and the horizontal height of the guide slope 17 on the side near the guide hole 18 is lower than the horizontal height on the other side.

[0040] In this embodiment, when the raw material enters the second grinding disc 16, the material is easily conveyed between the second grinding disc 16 and the first grinding disc 15 by means of the guide ramp 17, so that the raw material can be easily ground.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
