Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, and in particular to a feeding mechanism for a pellet mill. Background Technology

[0002] Currently, pelletizing biomass such as straw or wood into pellets is a widely accepted biomass utilization technology. By processing these biomass into high-density, high-calorific-value, and low-cost pellets, clean combustion of biomass is achieved, protecting the environment while creating economic value.

[0003] Existing pellet mills use a screw feeder to evenly feed raw materials into the pellet mill. In order to crush larger raw materials, two crushing rollers are usually set opposite each other inside the feeder's storage hopper to crush the raw materials. However, after the raw materials are poured into the storage hopper, they need to pass through the two crushing rollers and fall to the bottom of the storage hopper. For raw materials that do not need to be crushed, this will affect the feeding speed. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a feeding mechanism for a pellet mill. This addresses the technical problem that in existing pellet mills, a screw feeder is used to uniformly feed raw materials into the pellet mill. In order to crush larger raw materials, two crushing rollers are generally installed opposite each other inside the feeder's storage hopper to crush the raw materials. However, after the raw materials are poured into the storage hopper, they need to pass through the two crushing rollers and fall to the bottom of the storage hopper. For raw materials that do not need to be crushed, this will affect the feeding speed.

[0005] To achieve the above technical objectives, the present invention provides a feeding mechanism for a pellet mill, including a feeding pipe, an auger rod inside the feeding pipe, one end of the auger rod being connected to a first driving device for driving the auger rod to rotate, a storage hopper communicating with the inside of the feeding pipe on the side wall of the feeding pipe, two crushing rollers being arranged opposite each other inside the storage hopper, the crushing rollers being connected to a second driving device for driving the crushing rollers to rotate, a feeding hopper communicating with the inside of the storage hopper on the top of the storage hopper, and guide plates being provided inside the storage hopper and on both sides of the bottom opening of the feeding hopper, the upper sides of the two guide plates being connected to a swing assembly for driving the two guide plates to swing, so that the lower sides of the two guide plates are located between or offset from the two crushing rollers.

[0006] Furthermore, the oscillating assembly includes two gears, which are connected to two guide plates via a rotating shaft. The rotating shaft is mounted on the storage hopper via a bearing. The two gears mesh with a rack, which is linearly slidably connected to the outer wall of the storage hopper.

[0007] Furthermore, a T-shaped slide rail is installed on the outer wall of the storage hopper, and a T-shaped slide groove is provided on one side of the rack. The rack is linearly slidably connected to the outer wall of the storage hopper through the T-shaped slide groove and the T-shaped slide rail.

[0008] Furthermore, a handle is mounted on the rack.

[0009] Furthermore, the swing assembly also includes two limiting blocks installed on the outer wall of the storage hopper, with a rack positioned between the two limiting blocks.

[0010] Furthermore, the two ends of the rack are detachably connected to the two limiting blocks via fasteners.

[0011] Furthermore, the fastener includes a fixing plate, with two fixing grooves on one side of the fixing plate, and first fixing blocks that cooperate with the fixing grooves at both ends of the rack, and second fixing blocks that cooperate with the fixing grooves on both limiting blocks.

[0012] Furthermore, both the first fixing block and the second fixing block are T-shaped structures.

[0013] The beneficial effects of this utility model include: This utility model provides a feeding mechanism for a pellet mill, which can adjust the lower sides of the two guide plates to be between the two crushing rollers when the raw material needs to be crushed, so as to guide the raw material into the two crushing rollers for crushing. When the raw material does not need to be crushed, the lower sides of the two guide plates can be adjusted to be offset from the two crushing rollers, so that the raw material that does not need to be crushed falls directly into the bottom of the storage hopper without passing through the two crushing rollers, thereby improving the feeding speed.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] This utility model embodiment provides a feeding mechanism for a pellet mill, such as... Figure 1-2 As shown, the device includes a feeding pipe 1, inside which is an auger rod 2. One end of the auger rod 2 is connected to a first driving device 3 for driving the auger rod 2 to rotate. A storage hopper 4, communicating with the interior of the feeding pipe 1, is located on the side wall of the feeding pipe 1. Two crushing rollers 5 are arranged opposite each other inside the storage hopper 4. The crushing rollers 5 are connected to a second driving device 6 for driving the crushing rollers 5 to rotate. A feed hopper 7, communicating with the interior of the storage hopper 4, is located at the top of the storage hopper 4 and at the bottom openings of the feed hopper 7. Guide plates 8 are respectively located on the upper sides of the two guide plates 8. The two guide plates 8 are connected to the swing assembly 9, which drives the two guide plates 8 to swing so that the lower side of the two guide plates 8 is located between or away from the two crushing rollers 5. When the raw material needs to be crushed, the lower side of the two guide plates 8 can be adjusted to be between the two crushing rollers 5 to guide the raw material into the two crushing rollers 5 for crushing. When the raw material does not need to be crushed, the lower side of the two guide plates 8 can be adjusted to be away from the two crushing rollers 5 so that the raw material that does not need to be crushed falls directly into the bottom of the storage hopper 4 without passing through the two crushing rollers 5, thereby improving the feeding speed.

[0022] In this embodiment, the first driving device 3 is one of an electric motor, a hydraulic motor, or a pneumatic motor.

[0023] In this embodiment, the second driving device 6 includes a driving box, inside which two pulleys are rotatably mounted and connected by a belt drive. One of the pulleys is connected to a driving component for driving the pulley to rotate. The driving component is one of an electric motor, a hydraulic motor, or a pneumatic motor.

[0024] For the oscillating component 9, it only needs to be able to drive the two guide plates 8 to oscillate. Therefore, it is not limited to a specific structure. For example, in some embodiments, the oscillating component 9 uses a motor, hydraulic motor, or pneumatic motor to drive the guide plates 8 to rotate. In this embodiment, such as... Figure 3-4 As shown, the swing assembly 9 includes two gears 91, which are connected to two guide plates 8 via rotating shafts 92. The rotating shafts 92 are mounted on the storage hopper 4 via bearings. The two gears 91 mesh with racks 93, which are linearly slidably connected to the outer wall of the storage hopper 4. By sliding the racks 93, the two gears 91 can be driven to rotate, and the two gears 91 can drive the two guide plates 8 to swing. The structure is simple and the design is reasonable. The swing assembly 9 also includes two limiting blocks 94 installed on the outer wall of the storage hopper 4, with the rack 93 positioned between the two limiting blocks 94. The sliding position of the rack 93 can be restricted by two limiting blocks 94. When one end of the rack 93 slides to contact one of the limiting blocks 94, the two guide plates 8 are located between the two crushing rollers 6. When the other end of the rack 93 slides to contact the other limiting block 94, the lower sides of the two guide plates 8 are offset from the two crushing rollers 6. The adjustment is convenient. Moreover, the two ends of the rack 93 are detachably connected to the two limiting blocks 94 by fixing parts 95. After the adjustment is completed, the rack 93 and the limiting blocks 94 can be fixedly connected to prevent the guide plates 8 from swinging automatically after adjustment.

[0025] It should be noted that, as Figure 5 As shown, a T-shaped slide rail 41 is installed on the outer wall of the storage hopper 4, and a T-shaped slide groove 931 is provided on one side of the rack 93. The rack 93 is linearly slidably connected to the outer wall of the storage hopper 4 through the T-shaped slide groove 931 and the T-shaped slide rail 41.

[0026] It should be noted that a handle 932 is installed on the rack 93, which allows the rack 93 to be slid easily.

[0027] For the fastener 95, it only needs to satisfy the requirement of detachable connection between the rack 93 and the limiting block 94. Therefore, it is not limited to a specific structure. For example, in some embodiments, the fastener 95 adopts a latch lock. In this embodiment, the fastener 95 includes a fixing plate, and two fixing grooves 951 are provided on one side of the fixing plate. Both ends of the rack 93 are provided with first fixing blocks 933 that cooperate with the fixing grooves 951. Both limiting blocks 94 are provided with second fixing blocks 941 that cooperate with the fixing grooves 951. When one end of the rack 93 slides to one of the limiting blocks, the fastener can be detached from the rack 93. When block 94 contacts, the fixing member 95 is locked onto the first fixing block 933 and the second fixing block 941 of one of the limiting blocks 94 at one end of the rack 93. When the other end of the rack 93 slides to contact the other limiting block 94, the fixing member 95 is locked onto the first fixing block 933 and the second fixing block 941 of the other limiting block 94 at the other end of the rack 93. The operation is convenient. At the same time, the first fixing block 933 and the second fixing block 941 are both T-shaped structures, which can prevent the fixing member 95 from falling off the first fixing block 933 and the second fixing block 941.

[0028] Specific principle: When the raw material needs to be crushed, the sliding rack 93 makes one end of the rack 93 contact with one of its limiting blocks 94, and the fixing part 95 is locked on the first fixing block 933 at one end of the rack 93 and the second fixing block 941 of one of the limiting blocks 94. At the same time, the lower sides of the two guide plates 8 are adjusted to be between the two crushing rollers 5. After the raw material is poured into the feed hopper 7, it can be guided through the two guide plates 8 to the two crushing rollers 5 for crushing. When the raw material does not need to be crushed, the rack 93 is slid in the opposite direction to make the other end of the rack 93 contact with another limiting block 94, and the fixing part 95 is locked on the first fixing block 933 at the other end of the rack 93 and the second fixing block 941 of the other limiting block 94. At the same time, the lower sides of the two guide plates 8 are adjusted to be offset from the two crushing rollers 5. After the raw material is poured into the feed hopper 7, it falls directly into the bottom of the storage hopper 4 without passing through the two crushing rollers 5, thereby increasing the feeding speed.

[0029] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
