Abstract
Description
Technical Field
[0001] This utility model relates to the field of green coffee bean production technology, specifically to a green coffee bean feeding mechanism. Background Technology
[0002] Coffee bean feeding is a crucial step in transporting green coffee beans from the storage area to the processing equipment, requiring a balance between efficiency and quality protection. The feeding system typically consists of a bean storage bin, a conveying device, and a control unit. The storage bin buffers the green beans and prevents clumping through a de-bridging device. Conveying methods include screw conveyors and pneumatic conveyors. Screw conveyors are suitable for short-distance, enclosed transport, while pneumatic conveyors enable long-distance, dust-free feeding and can be combined with an air separator to remove impurities.
[0003] Current green coffee bean feeding systems face two technical bottlenecks in the conveying process:
[0004] On the one hand, due to the mechanical transmission characteristics of the mainstream screw conveyor method, raw beans are prone to breakage due to the squeezing and friction between the screw blades and the conveying pipe wall. At the same time, the accumulation of bean shell fragments and dust can easily cause blockage of the conveying channel.
[0005] On the other hand, although airflow conveying can achieve dust-free transmission, it cannot effectively separate small raw beans and impurities (such as broken beans and stones) based on the principle of wind speed screening. Unqualified particles mixed into the material flow not only affect the uniformity of subsequent roasting, but may also damage the roaster drum due to hard objects jamming.
[0006] Existing technologies lack integrated solutions that combine low-damage conveying with precise particle size screening, and there is an urgent need to develop new feeding systems to solve multiple problems such as mechanical damage, clogging risk, and impurity contamination. Utility Model Content
[0007] The purpose of this invention is to provide a coffee bean feeding mechanism to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a coffee green bean feeding mechanism, including a bottom support, a support frame fixedly connected to the top right side of the bottom support, a feeding bin fixedly connected to the top of the support frame, a shaking feeding component fixedly connected to the bottom left side of the feeding bin, a shaking feeding component installed on the top of the bottom support, and a dust removal component installed on the top of the bottom support and the outside of the shaking feeding component.
[0009] The vibrating feeding assembly includes a spring, which is fixedly connected to the four corners of the top of the bottom bracket. A support block is fixedly connected to the bottom of the spring, and a feeding trough is fixedly connected to the inner side of the support block. A through hole is opened in the middle of the feeding trough. A sliding rod is fixedly connected to the middle of the bottom of the feeding trough, and a contact block is fixedly connected to the bottom end of the sliding rod. A rotating rod is rotatably connected to the top of the bottom bracket corresponding to the contact block. A cam is fixedly connected to the middle of the rotating rod. A motor is fixedly connected to the rear side of the bottom bracket corresponding to the rotating rod. Limit pins are fixedly connected to both the front and rear sides of the feeding trough.
[0010] Preferably, the motor is equipped with an output shaft, and the motor is fixedly connected to the rotating rod through the output shaft.
[0011] Preferably, the discharge chute is located on the right side of the feeding chute, and the left side of the discharge chute does not contact the bottom of the feeding chute, with a gap in the middle for the feeding chute to vibrate up and down.
[0012] Preferably, the through holes are densely arranged at equal intervals in the middle, and the right side of the feeding trough is higher than the left side.
[0013] Preferably, the dust removal assembly includes a support rod, which is fixedly connected to the top of the bottom bracket. A protective shell is fixedly connected to the top of the support rod, and a fan is fixedly connected to the top of the protective shell. A sliding sleeve is fixedly connected to the bottom of the protective shell corresponding to a sliding rod, and a sliding rod is slidably connected inside the sliding sleeve.
[0014] Preferably, the protective shell has a ventilation hole at the top, and a fan is installed on the top of the ventilation hole.
[0015] Preferably, the protective shell is disposed in the middle of the feeding trough, and the through hole is disposed within the internal range of the protective shell. The front and rear sides of the protective shell are provided with sliding grooves corresponding to the limiting pins, and the limiting pins are slidably connected in the sliding grooves.
[0016] Compared with the prior art, the present invention provides a coffee green bean feeding mechanism, which has the following beneficial effects:
[0017] 1. This green coffee bean feeding mechanism uses a vibrating feeding component to drive a rotating rod via a motor. A contact block in the middle of the rotating rod periodically impacts the bottom of a sliding rod, causing the feeding trough to vibrate up and down under spring support. The inclined design of the right side of the feeding trough, higher than the left, combined with the inertial force generated by the vibration, propels the green beans from right to left. Dense perforations in the middle allow broken beans, pebbles, and other impurities smaller than 5mm to fall off, while whole green beans are conveyed along the trough. Springs buffer the impact of the vibration, preventing damage to the green beans from hard collisions. Simultaneously, during the vibration, bean shell fragments are dislodged and discharged through the perforations, preventing blockage of the conveying channel.
[0018] Compared to screw conveyors, the breakage rate of raw beans is reduced, and the vibrating conveyor has no mechanical squeezing parts, eliminating the blockage problem caused by debris accumulation.
[0019] 2. This coffee bean feeding mechanism features a protective shell housing a dust removal component within the through-hole area of the feeding trough. When the top fan operates, it creates a downward negative airflow. During the shaking process, as impurities fall through the through-holes, the airflow from the fan draws light impurities such as dust and broken beans into the protective shell and discharges them, while heavier impurities such as pebbles fall directly into the bottom collection trough. The sliding grooves at the front and rear of the protective shell engage with the limiting pins of the feeding trough, ensuring the sealing of the dust removal area during shaking and allowing for precise separation of impurity particles.
[0020] This solves the problem that airflow conveying cannot screen small particulate impurities and avoids the risk of hard objects getting stuck in the baking machine drum. Attached Figure Description

[0027] 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.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] This utility model provides the following technical solution:
[0030] Example 1: Please refer to Figure 1-4 A coffee green bean feeding mechanism includes a bottom support 1, a support frame 5 fixedly connected to the top right side of the bottom support 1, a feeding bin 4 fixedly connected to the top of the support frame 5, a shaking feeding component 3 fixedly connected to the bottom left side of the feeding bin 4, a shaking feeding component 3 installed on the top of the bottom support 1, and a dust removal component 2 installed on the top of the bottom support 1 and the outside of the shaking feeding component 3.
[0031] The vibrating feeding assembly 3 includes a spring 39, which is fixedly connected to the four corners of the top of the bottom bracket 1. A support block 38 is fixedly connected to the bottom of the spring 39. A feeding trough 31 is fixedly connected to the inner side of the support block 38. A through hole 36 is opened in the middle of the feeding trough 31. A sliding rod 32 is fixedly connected to the middle of the bottom of the feeding trough 31. A contact block 33 is fixedly connected to the bottom end of the sliding rod 32. A rotating rod 35 is rotatably connected to the top of the bottom bracket 1 corresponding to the contact block 33. A receiving cam 34 is fixedly connected to the middle of the rotating rod 35. A motor 37 is fixedly connected to the rear side of the bottom bracket 1 corresponding to the rotating rod 35. Limit pins 311 are fixedly connected to both the front and rear sides of the feeding trough 31.
[0032] The vibrating feeding assembly 3 causes the motor 37 to drive the rotating rod 35 to rotate. The contact block 33 in the middle of the rotating rod 35 periodically impacts the bottom of the sliding rod 32, causing the feeding trough 31 to vibrate up and down under the support of the spring 39. The inclined design of the feeding trough 31, with the right side higher than the left, combined with the inertial force generated by the vibration, pushes the raw beans to slide from right to left. The dense through holes 36 in the middle allow impurities such as broken beans and stones with a particle size of less than 5mm to fall off, while whole raw beans are conveyed along the trough. The spring 39 buffers the impact of the vibration, preventing the raw beans from being damaged by hard collisions. At the same time, during the vibration, bean shell fragments fall off with the vibration and are discharged through the through holes 36, preventing blockage of the conveying channel.
[0033] Compared to screw conveyors, the breakage rate of raw beans is reduced, and the vibrating conveyor has no mechanical squeezing parts, eliminating the blockage problem caused by debris accumulation.
[0034] The motor 37 is equipped with an output shaft, and the motor 37 is fixedly connected to the rotating rod 35 through the output shaft.
[0035] The discharge chute 41 is located on the right side of the feeding chute 31, and the left side of the discharge chute 41 does not contact the bottom of the feeding chute 31. A gap is provided in the middle for the feeding chute 31 to vibrate up and down.
[0036] Through holes 36 are densely arranged at equal intervals in the middle, and the right side of the feeding trough 31 is higher than the left side.
[0037] Example 2: Please refer to Figure 1-4 Furthermore, based on Embodiment 1, the dust removal component 2 includes a support rod 22, which is fixedly connected to the top of the bottom bracket 1. A protective shell 21 is fixedly connected to the top of the support rod 22, and a fan 23 is fixedly connected to the top of the protective shell 21. A sliding sleeve 26 is fixedly connected to the bottom of the protective shell 21 corresponding to the sliding rod 32, and the sliding rod 32 is slidably connected inside the sliding sleeve 26.
[0038] The protective shell 21 of the dust removal component 2 covers the area of the through hole 36 in the feeding trough 31. When the top fan 23 operates, it creates a downward airflow negative pressure. When impurities fall through the through hole 36 during the shaking process, the airflow generated by the fan 23 draws light impurities such as dust and broken beans into the protective shell 21 and discharges them, while heavy impurities such as stones fall directly into the bottom collection tank. The sliding grooves 25 at the front and rear of the protective shell 21 slide and engage with the limiting pins 311 of the feeding trough 31 to ensure the sealing of the dust removal area during the shaking process, allowing for precise separation of impurity particles.
[0039] This solves the problem that airflow conveying cannot screen small particulate impurities and avoids the risk of hard objects getting stuck in the baking machine drum.
[0040] The protective shell 21 has a ventilation hole 24 on its top, and a fan 23 is installed on the top of the ventilation hole 24.
[0041] The protective shell 21 is located in the middle of the feeding trough 31, and the through hole 36 is located within the internal range of the protective shell 21. The front and rear sides of the protective shell 21 are provided with sliding grooves 25 corresponding to the limiting pins 311, and the limiting pins 311 are slidably connected in the sliding grooves 25.
[0042] In actual operation, when this device is in use, the shaking feeding assembly 3 causes the motor 37 to drive the rotating rod 35 to rotate. The contact block 33 in the middle of the rotating rod 35 periodically impacts the bottom of the sliding rod 32, causing the feeding trough 31 to shake up and down under the support of the spring 39. The inclined design of the feeding trough 31, with the right side higher than the left, combined with the inertial force generated by the shaking, pushes the raw beans to slide from right to left. The dense through holes 36 in the middle allow impurities such as broken beans and stones with a particle size of less than 5mm to fall off, while whole raw beans are conveyed along the trough. The spring 39 buffers the impact of the shaking, preventing the raw beans from being damaged by hard collisions. At the same time, during the shaking process, bean shell fragments fall off with the vibration and are discharged through the through holes 36, preventing blockage of the conveying channel.
[0043] Compared to screw conveyors, the breakage rate of raw beans is reduced, and the vibrating conveyor has no mechanical squeezing parts, eliminating the blockage problem caused by debris accumulation.
[0044] The protective shell 21 of the dust removal component 2 covers the area of the through hole 36 in the feeding trough 31. When the top fan 23 operates, it creates a downward airflow negative pressure. When impurities fall through the through hole 36 during the shaking process, the airflow generated by the fan 23 draws light impurities such as dust and broken beans into the protective shell 21 and discharges them, while heavy impurities such as stones fall directly into the bottom collection tank. The sliding grooves 25 at the front and rear of the protective shell 21 slide and engage with the limiting pins 311 of the feeding trough 31 to ensure the sealing of the dust removal area during the shaking process, allowing for precise separation of impurity particles.
[0045] This solves the problem that airflow conveying cannot screen small particulate impurities and avoids the risk of hard objects getting stuck in the baking machine drum.
