Description

Technical Field

[0001] This utility model relates to the field of biomass fuel technology, and in particular to a feeding and metering device for a crusher. Background Technology

[0002] Biomass briquettes are made by collecting traditional crop straw and waste bamboo and wood chips, which are originally low in density and have low calorific value per unit volume. They are then processed through crushing, mixing, drying, and extrusion without the addition of any additives to produce a dense and relatively uniform solid fuel. Due to its high combustion efficiency and low cost, it is being used and promoted more and more widely.

[0003] For example, a Chinese patent discloses a feeding and metering device for a biomass fuel crusher (patent number: CN219804773U). Through the cooperation of a load plate, a counterweight box, a counterweight block, and a rotating shaft, the opening at the lower end of the metering tube is closed by the load plate. The raw materials input through the feeding assembly accumulate inside the metering tube. When the total weight of the raw materials exceeds the weight of the counterweight box, the load plate rotates, allowing the raw materials in the metering tube to fall into the crusher with the same weight. Simultaneously, as the load plate rotates, a trigger switch changes from closed to open, stopping the feeding assembly. This allows for convenient control of the weight of the raw materials input into the crusher, reducing the likelihood of crusher malfunctions and thus improving production efficiency.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, the device does not have a squeezing mechanism. When the raw material has branches or is too wide, it may cause material to get stuck inside the metering tube, making it difficult to fall into the crusher. If too much material gets stuck inside the metering tube after long-term use, the device may fail to operate. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a feeding and metering device for a crusher, which solves the technical problem mentioned above that the device lacks a squeezing mechanism, which may cause material to get stuck inside the metering tube when the raw material has branches or is too wide, making it difficult for the material to fall into the crusher. Furthermore, if too much material gets stuck inside the metering tube after prolonged use, the device may become inoperable.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A feeding and metering device for a crusher includes a base, an extrusion box is fixedly installed inside the base, a motor is fixedly installed on the side wall of the extrusion box, a first gear is fixedly installed on the side wall of the motor output shaft, a rotating mechanism is meshed on the side wall of the first gear, the rotating mechanism includes a second gear, and an extrusion cylinder is fixedly installed at the end of the second gear and the first gear away from the motor.

[0010] Preferably, a transmission assembly is fixedly installed on the side wall of the motor output shaft.

[0011] Preferably, a connecting shaft is fixedly installed at the end of the transmission assembly away from the motor, and a missing gear is fixedly installed at the end of the connecting shaft away from the transmission assembly, with a rack frame meshing on the side wall of the missing gear.

[0012] Preferably, a sliding plate is fixedly installed on the side wall of the rack frame.

[0013] Preferably, a pressure plate is fixedly installed at the bottom of the rack frame, a cutting frame is fixedly installed at the bottom of the pressure plate, a cylinder is fixedly installed inside the base, and a pneumatic rod is fixedly installed at the output end of the cylinder.

[0014] Preferably, a metering box is fixedly installed at the end of the pneumatic rod away from the cylinder, a mounting plate is hinged to the bottom of the metering box, a baffle is fixedly installed on the side wall of the metering box, and a brush is fixedly installed on the side wall of the pneumatic rod.

[0015] (III) Beneficial Effects

[0016] 1. By starting the motor, the motor drives the first gear to rotate clockwise, which in turn drives the second gear to rotate counterclockwise. The second and first gears then drive the extrusion cylinder to rotate. The motor drives the transmission assembly to rotate counterclockwise, which in turn drives the connecting shaft to rotate clockwise. The connecting shaft then drives the missing gear to rotate clockwise, which in turn drives the rack frame to reciprocate up and down. The rack frame then drives the sliding plate to reciprocate up and down, which in turn drives the pressure plate to reciprocate up and down. The pressure plate then drives the cutting frame to reciprocate up and down. When material is placed inside the extrusion chamber, the pressure plate presses the material down from top to bottom, and the cutting frame cuts the material. The material is then extruded through the extrusion cylinder, resulting in a more uniform and regular material, reducing the likelihood of jamming and thus achieving the function of reducing material jamming.

[0017] 2. By starting the cylinder, the cylinder drives the pneumatic rod to extend and retract repeatedly. When the dust generated after the extrusion cylinder is squeezed falls into the base, the brush cleans the inside of the base. The pneumatic rod drives the metering box to move back and forth. When the metering box moves backward and the mounting plate is separated from the base, the mounting plate flips clockwise, and the material inside the metering box falls out, thus achieving the function of metered feeding.

[0024] This application provides a feeding and metering device for a crusher, effectively solving the problem mentioned above where the device lacks an extrusion mechanism. When the raw material has knots or is wide, it may become stuck inside the metering tube, making it difficult for the material to fall into the crusher. Excessive material buildup in the metering tube over a long period may cause the device to malfunction. By starting the motor, the motor drives the first gear to rotate clockwise, which in turn drives the second gear to rotate counterclockwise. The second and first gears respectively drive the extrusion cylinder to rotate. The motor drives the transmission assembly to rotate counterclockwise, which in turn drives the connecting shaft to rotate clockwise. The connecting shaft drives the missing gear to rotate clockwise, which in turn drives the rack frame to reciprocate up and down. The rack frame then drives the sliding plate... The rack and pinion frame moves up and down, driving the pressure plate to move up and down. The pressure plate, in turn, drives the cutting frame to move up and down. Material is placed inside the extrusion chamber, and the pressure plate presses the material down from top to bottom. The cutting frame cuts the material, which is then squeezed by the extrusion cylinder. The squeezed material becomes regular and uniform, reducing the chance of jamming. By activating the cylinder, the pneumatic rod extends and retracts repeatedly. Dust generated after the extrusion cylinder falls into the base, where a brush cleans the interior. The pneumatic rod drives the metering box to move back and forth. When the metering box moves backward and the mounting plate detaches from the base, the mounting plate rotates clockwise, causing the material inside the metering box to fall out, thus achieving the function of metered feeding.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem mentioned above that the device lacks an extrusion mechanism, which may cause material to get stuck inside the metering tube when the raw material has branches or is too wide, making it difficult for the material to fall into the crusher. Furthermore, prolonged use may cause excessive material to get stuck inside the metering tube, potentially rendering the device inoperable. The overall concept is as follows: A feeding metering device for a crusher includes a base 11, an extrusion box 12 fixedly installed inside the base 11, a motor 13 fixedly installed on the side wall of the extrusion box 12, a first gear 14 fixedly installed on the side wall of the output shaft of the motor 13, a rotating mechanism meshing with the side wall of the first gear 14, the rotating mechanism including a second gear 15, an extrusion cylinder 16 fixedly installed at the end of the second gear 15 and the first gear 14 away from the motor 13, the side wall of the extrusion cylinder 16 rotatably mounted to the extrusion box 12, a transmission assembly 17 fixedly installed on the side wall of the output shaft of the motor 13, a connecting shaft 18 fixedly installed at the end of the transmission assembly 17 away from the motor 13, a missing gear 19 fixedly installed at the end of the connecting shaft 18 away from the transmission assembly 17, a rack frame 21 meshing with the side wall of the missing gear 19, and the gear... A sliding plate 22 is fixedly installed on the side wall of the rack frame 21. The sliding plate 22 is slidably installed inside the extrusion box 12. A pressure plate 23 is fixedly installed at the bottom of the rack frame 21. A cutting frame 24 is fixedly installed at the bottom of the pressure plate 23. By starting the motor 13, the motor 13 drives the first gear 14 to rotate clockwise. The first gear 14 drives the second gear 15 to rotate counterclockwise. The second gear 15 and the first gear 14 respectively drive the extrusion cylinder 16 to rotate. The motor 13 drives the transmission assembly 17 to rotate counterclockwise. The transmission assembly 17 drives the connecting shaft 18 to rotate clockwise. The connecting shaft 18 drives the missing gear 19 to rotate clockwise. The missing gear 19 drives the rack frame 21 to move up and down reciprocally. The rack frame 21 drives the sliding plate 22 to move up and down reciprocally. The rack frame 21 drives the pressure plate 23 to move up and down reciprocally. The pressure plate 23 drives the cutting frame 24 to move up and down reciprocally. The material is put into the extrusion box 12. The pressure plate 23 presses the material from top to bottom. The cutting frame 24 cuts the material. The material is extruded through the extrusion cylinder 16. The extruded material becomes regular and uniform, reducing the possibility of jamming, thereby achieving the function of reducing jamming.

[0027] A cylinder 25 is fixedly installed inside the base 11. A pneumatic rod 26 is fixedly installed at the output end of the cylinder 25. A metering box 28 is fixedly installed at the end of the pneumatic rod 26 away from the cylinder 25. The metering box 28 with a fixed volume can meter the material it conveys. By starting the cylinder 25, the cylinder 25 drives the pneumatic rod 26 to repeatedly extend and retract. When the dust generated after the extrusion cylinder 16 extrudes falls into the base 11, the brush 27 cleans the inside of the base 11. The pneumatic rod 26 drives the metering box 28 to move back and forth. When the metering box 28 moves backward, the mounting plate 29 is removed from the base 11. The mounting plate 29 then rotates clockwise, and the material inside the metering box 28 falls out, thus achieving the function of metered feeding.

[0028] A mounting plate 29 is hinged to the bottom of the metering box 28, a baffle 31 is fixedly installed on the side wall of the metering box 28, and a brush 27 is fixedly installed on the side wall of the pneumatic rod 26 to clean the inside of the base 11.

[0029] To address the problems existing in the prior art, this utility model provides a feeding and metering device for a crusher. By starting the motor 13, the motor 13 drives the first gear 14 to rotate clockwise, which in turn drives the second gear 15 to rotate counterclockwise. The second gear 15 and the first gear 14 respectively drive the extrusion cylinder 16 to rotate. The motor 13 drives the transmission assembly 17 to rotate counterclockwise, which in turn drives the connecting shaft 18 to rotate clockwise. The connecting shaft 18 drives the missing gear 19 to rotate clockwise, which in turn drives the rack frame 21 to reciprocate up and down. The rack frame 21 then drives the sliding plate 22 to reciprocate up and down, which in turn drives the pressure plate 23 to reciprocate up and down. The pressure plate 23 then drives the cutting frame 24 to reciprocate up and down. The material is placed inside the extrusion chamber 12, and the pressure plate 23 presses the material from top to bottom. The cutting frame 24 cuts the material, and the material is squeezed through the extrusion cylinder 16. The squeezed material becomes regular and uniform, reducing the possibility of jamming. By starting the cylinder 25, the cylinder 25 drives the pneumatic rod 26 to repeatedly extend and retract. When the dust generated after the extrusion cylinder 16 squeezes falls into the base 11, the brush 27 cleans the inside of the base 11. The pneumatic rod 26 drives the metering box 28 to move back and forth. When the metering box 28 moves backward, the mounting plate 29 is removed from the base 11 and rotates clockwise. The material inside the metering box 28 falls out, thus achieving the function of metered feeding.

[0030] Working principle:

[0031] The first step involves starting motor 13, which drives the first gear 14 to rotate clockwise, which in turn drives the second gear 15 to rotate counterclockwise. The second gear 15 and the first gear 14 then drive the extrusion cylinder 16 to rotate. Motor 13 drives the transmission assembly 17 to rotate counterclockwise, which in turn drives the connecting shaft 18 to rotate clockwise. The connecting shaft 18 then drives the missing gear 19 to rotate clockwise, which in turn drives the rack frame 21 to reciprocate up and down. The rack frame 21 then drives the sliding plate 22 to reciprocate up and down, which in turn drives the pressure plate 23 to reciprocate up and down. The pressure plate 23 then drives the cutting frame 24 to reciprocate up and down. Material is placed inside the extrusion chamber 12, and the pressure plate 23 presses the material down from top to bottom. The cutting frame 24 cuts the material. The material is then extruded through the extrusion cylinder 16, resulting in a more uniform and regular material, reducing the likelihood of jamming and thus achieving the function of reducing material jamming.

[0032] The second step involves activating cylinder 25, which drives pneumatic rod 26 to repeatedly extend and retract. When dust generated after extrusion by extrusion cylinder 16 falls into the base 11, brush 27 cleans the inside of base 11. Pneumatic rod 26 drives metering box 28 to move back and forth. When metering box 28 moves backward and mounting plate 29 detaches from base 11, mounting plate 29 rotates clockwise, causing material inside metering box 28 to fall out, thus achieving the function of metered feeding.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
