Description

Technical Field

[0001] This invention relates to the field of intelligent transportation equipment for agricultural products, and in particular to a dry chili suction feeding machine. Background Technology

[0002] Dried chili peppers are chili pepper products made by dehydrating and drying fresh chili peppers. They are widely used in cooking because they are easy to store and have a rich flavor. Dried chili peppers are agricultural products. After drying and screening, they need to be transported and loaded using an intelligent agricultural product transportation system to facilitate subsequent processing. When conveying dried chilies, the common methods vary depending on the specific circumstances. Generally, one method involves directly sucking up the chilies with a suction head, while another involves feeding the chilies through a hopper and then feeding them through a suction pipe. In practice, the hopper is typically used to feed the screened chilies. A chili suction feeding machine utilizes wind or negative pressure to convey the chilies. The suction port is sealed to the suction fan to provide suction. An interceptor net is installed inside the suction port to prevent chilies from entering the fan. However, in traditional chili suction feeding machines, the interceptor net is easily sucked onto the surface by the suction, affecting its effectiveness. Furthermore, regular cleaning by staff is required, making feeding inconvenient. Therefore, a chili suction feeding machine is needed to solve these problems. Summary of the Invention

The mounting plate is installed on one side of the hopper, and a motor is installed at the top of the mounting plate. A rotating shaft is installed at one end of the motor. One end of the rotating shaft passes through the interior of the bottom of the hopper. A connecting plate is installed on the outside of one end of the rotating shaft, and a material distribution plate is provided inside the hopper on the outside of the other end of the rotating shaft.

[0011] Preferably, a bevel gear set is installed at the top of the hopper, a dust cover is installed on the outside of the bevel gear set, a connecting shaft is installed at one end of the bevel gear set, a rotating disk is installed at one end of the connecting shaft, the rotating disk is connected to the connecting disk by a belt, a stirring shaft is installed at the bottom of the bevel gear set, and a stirring frame is installed on the outside of the stirring shaft.

[0012] Preferably, the stirring rack is provided in three sets, and the three sets of stirring racks are distributed in a circle on the outside of the stirring shaft.

[0013] Preferably, the material distribution plate is provided in multiple sets, and the multiple sets of material distribution plates are arranged in a ring on the outer side of one end of the rotating shaft.

[0014] The present invention provides a dried chili suction feeding machine, the advantages of which are: By incorporating a cleaning structure, when the interceptor is intercepting, small and lightweight dried chilies will be sucked onto one side of the interception net inside the interceptor. At this time, the impeller can utilize the airflow energy of the device itself to achieve a rotation effect, thereby driving the cleaning frame to rotate and cleaning the dried chilies on the surface of the interception net, thus achieving the self-cleaning effect of the interception net. Furthermore, when the impeller rotates, it drives the second gear to rotate. Through the cooperation between the second gear and the first gear, a differential speed effect can be achieved, allowing the connector to drive the mounting shaft to rotate slowly, thus completing the differential speed operation. Furthermore, when the cleaning rack rotates, it can sweep away the dried chili peppers adsorbed on the surface of the interception net inside the interception rack. Whenever the cleaning rack rotates to a vertical position, the slider inside the cleaning rack is simultaneously subjected to the combined effects of gravity and centrifugal force, sliding rapidly downwards along the slide groove, pushing the pusher plate at the bottom of the connecting plate downwards, thereby pushing the dried chili peppers on the surface of the interception net downwards and detaching them from the surface of the interception net. This completely solves the problem of dried chili pepper adsorption residue and prevents the situation where some chili peppers are firmly adsorbed by negative pressure and cannot be scraped off by relying solely on the cleaning rack to scrape them off. Furthermore, the pusher plate actively pushes the dried chilies downwards, and the combined force of gravity causes the dried chilies to fall off quickly. This upgrades the cleaning process from passive sweeping to active pushing, completely breaking the adhesion between the dried chilies and the interception net. This makes it easier to clean the dried chilies on the surface of the interception net inside the interception frame without any manual operation, thus completing the self-cleaning of the dried chilies on the surface of the interception net. With a feeding structure, when the dried chilies are fed through suction, the bevel gear set rotates, driving the mixing frame to rotate. The mixing frame agitates the dried chilies inside the feeding hopper during rotation. Because the mixing frame has a stirring rod inside, it can break up any clumps of dried chilies. Dried chilies are prone to clumping due to compression and moisture during storage, and direct feeding can clog the feeding hopper outlet. Furthermore, dried chilies are lightweight and sticky, and when fed, they tend to form arched bridges in the feeding hopper, resulting in a hollow center and piled-up edges, which can interrupt feeding. Therefore, the use of the mixing frame can continuously disturb the material, break the mechanical balance formed by the bridges, and allow the dried chilies to flow continuously towards the bottom outlet of the hopper, making it less likely to clog. Furthermore, after the motor starts, it will drive the rotating shaft to rotate, which in turn will drive the distribution plate to rotate, thus distributing the dried chilies. This prevents the dried chilies from overflowing due to gravity, reducing pipe blockage. The rotating distribution plate can also stably control the feeding speed, preventing inconsistent amounts. The combination of mixing by the mixing rack and distribution by the distribution plate ensures a consistently stable feeding volume, guaranteeing stable negative pressure in the suction system. This mechanical disturbance during dried chili conveying solves the problems of clumping, bridging, and uneven feeding inside the hopper. At the same time, the material control structure of the distribution plate makes the entire suction feeding system more stable and efficient, especially suitable for materials like dried chilies that are prone to clumping and have poor flowability.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 The present invention provides a dried chili suction feeding machine, comprising a suction pipe 1 and a connecting pipe 2; A connecting pipe 2 is installed at one end of the suction pipe 1, a hopper 4 is installed at the top of the connecting pipe 2, a separation box 5 is installed at the other end of the suction pipe 1, an installation pipe 8 is installed on one side of the separation box 5, a suction fan 6 is installed on one side of the installation pipe 8, and a cleaning structure 7 is provided inside the separation box 5.

[0019] See Figures 1-3 The hopper 4 is equipped with a feeding structure 3, which includes a mounting plate 301. The mounting plate 301 is installed on one side of the hopper 4. A motor 303 is installed on the top of the mounting plate 301. A rotating shaft 3010 is installed on one end of the motor 303. One end of the rotating shaft 3010 passes through the interior of the bottom of the hopper 4. A connecting plate 302 is installed on the outer side of one end of the rotating shaft 3010. A material distribution plate 309 is installed on the outer side of the other end of the rotating shaft 3010 inside the hopper 4. A bevel gear set 307 is installed at the top of the hopper 4. A dust cover 306 is installed on the outside of the bevel gear set 307. A connecting shaft 305 is installed at one end of the bevel gear set 307. A rotating disk 304 is installed at one end of the connecting shaft 305. The rotating disk 304 is connected to the connecting disk 302 via a belt. A stirring shaft 3011 is installed at the bottom of the bevel gear set 307. A stirring frame 308 is installed on the outside of the stirring shaft 3011. Three sets of stirring racks 308 are provided, and the three sets of stirring racks 308 are distributed in a circle on the outside of the stirring shaft 3011; Multiple sets of material distribution plates 309 are provided, and the multiple sets of material distribution plates 309 are arranged in a ring on the outer side of one end of the rotating shaft 3010.

[0020] Specifically, in this embodiment, during the suction feeding of dried chili peppers, the worker continuously pours the screened dried chili peppers into the hopper 4. After the dried chili peppers fall into the hopper 4, the motor 303 is started via the control panel on one side of the separator 5. The motor 303, upon starting, drives the rotating shaft 3010 to rotate. The rotating shaft 3010, in turn, drives the connecting disc 302 to rotate. The connecting disc 302, in turn, drives the rotating disc 304 to rotate. The rotating disc 304, in turn, drives the bevel gear set 307 to rotate via the connecting shaft 305. During rotation, unit 307 drives the mixing frame 308 to rotate via the mixing shaft 3011. The mixing frame 308, during rotation, agitates the dried chilies inside the hopper 4. Because the mixing frame 308 has an internal mixing rod, it can break up any clumps of dried chilies. Dried chilies are prone to clumping due to compression and moisture absorption during storage; direct feeding would clog the outlet of the hopper 4. Furthermore, dried chilies are lightweight and sticky, easily forming arched bridges inside the hopper during feeding, resulting in a hollow center and accumulated material around the edges, causing feeding interruptions. The mixing frame 308 continuously agitates the material, breaking up these bridges. The mechanical balance ensures a continuous flow of dried chilies towards the bottom outlet, preventing blockages. Furthermore, after starting, the motor 303 drives the rotating shaft 3010, which in turn rotates the distribution plate 309, thus distributing the dried chilies and preventing them from flowing downwards in large quantities due to gravity, reducing pipe blockages. The rotating distribution plate 309 also stably controls the feeding speed, preventing inconsistent amounts. Excessive feeding instantly increases airflow resistance, causing a sudden rise in negative pressure; insufficient feeding results in empty pipe transport, wasting energy. Therefore, the mixing rack 308 and the distribution plate 309 ensure a stable feeding rate and maintain stable negative pressure in the suction system. A certain gap is reserved between one side of the distribution plate 309 and the inner wall of the hopper 4 to facilitate airflow. The reserved gap prevents chili peppers from passing through, thus solving the problems of clumping, bridging, and uneven feeding inside the hopper 4 during the conveying of dried chili peppers through mechanical disturbance. At the same time, the rotating material control structure of the distribution plate 309 makes the entire suction feeding system more stable and efficient, especially suitable for materials such as dried chili peppers that are prone to clumping and have poor flowability.

[0021] See Figures 4-10The cleaning structure 7 includes an interceptor frame 701, which is installed inside one side of the separation box 5. An installation shaft 704 is installed in the middle of the interceptor frame 701, and a support sleeve is installed on the outside of the installation shaft 704. An installation bracket 706 is installed at one end of the installation shaft 704, and a support block is installed at the bottom of the installation bracket 706. A second gear 708 is installed in the middle of the interior of the installation bracket 706, and a first gear 707 is installed on the outside of the second gear 708. A gear ring 709 is installed on the outside of the first gear 707 and is fixed to the inside of the installation bracket 706. An impeller 702 is installed at one end of the second gear 708, and a connector 7010 is installed at one end of the first gear 707. One end of the connector 7010 is connected to one end of the installation shaft 704. A discharge port 703 is installed at the bottom of the separation box 5. A cleaning frame 705 is installed on the outside of the mounting shaft 704. A sliding groove 7011 is opened inside the cleaning frame 705. A slider 7012 is installed inside the sliding groove 7011. Connecting plates 7013 are installed on both sides of the top of the slider 7012. A pusher plate 7014 is installed at the bottom of the connecting plate 7013. The first gear 707 is provided in multiple sets, and the multiple sets of first gears 707 are distributed in a ring outside the second gear 708. The slider 7012 slides inside the slide groove 7011, and a sliding connection is formed between the slider 7012 and the slide groove 7011. The inner side of the gear ring 709 is provided with several teeth, and the gear ring 709 meshes with the first gear 707; Two sets of pusher plates 7014 are provided, and the two sets of pusher plates 7014 are symmetrically distributed on both sides of the cleaning frame 705.

[0022] Specifically, in this embodiment, when the dried chilies are being fed, the suction fan 6 is activated to generate suction, which transports the dried chilies through the suction pipe 1 into the separation box 5. When the dried chilies are sucked into the separation box 5, they are intercepted by the intercepting net inside the intercepting frame 701. Then, the dried chilies fall into the discharge port 703 by their own gravity, allowing them to fall onto the conveyor belt for subsequent processing steps, thus completing the suction feeding process. When the intercepting frame 701 is intercepting, a small number of smaller, lighter dried chilies will be sucked into the intercepting frame 701. On one side of the interception net, when suction passes through the inside of the mounting pipe 8, the flowing air drives the impeller 702 to rotate. The rotation of the impeller 702 drives the second gear 708 to rotate, which in turn drives the first gear 707 to rotate. The rotation of the first gear 707 drives the connector 7010 to rotate. The cooperation of the second gear 708 and the first gear 707 creates a deceleration effect, allowing the connector 7010 to drive the mounting shaft 704 to rotate slowly. The rotation of the mounting shaft 704 then drives the cleaning frame 70... 5. Rotation: When the cleaning frame 705 rotates, it can sweep away the dried chili peppers adsorbed on the surface of the interception net inside the interception frame 701. Furthermore, whenever the cleaning frame 705 rotates to a vertical position, the slider 7012 inside the cleaning frame 705, under the combined action of gravity and centrifugal force, slides rapidly downwards along the slide groove 7011, pushing the pusher plate 7014 at the bottom of the connecting plate 7013 downwards. This pushes the dried chili peppers on the surface of the interception net downwards, detaching them from the net surface, thus solving the problem of dried chili pepper residue and preventing some chili peppers from being trapped by negative pressure due to the cleaning frame 705 scraping alone. The dried chilies are firmly adhered and may not be scraped off. However, the pusher plate 7014 actively pushes the chilies, applying a downward thrust that, combined with gravity, causes the dried chilies to fall off quickly. This upgrades the cleaning process from passive sweeping to active pushing, completely breaking the adhesion between the dried chilies and the interception net. This makes it much easier to clean the dried chilies from the surface of the interception net inside the interception frame 701 without any manual operation. The impeller 702 utilizes the airflow energy of the device itself to achieve a self-cleaning effect on the interception net, eliminating the need for an additional drive motor and simultaneously solving the problem of dried chili adhesion, thus completing the cleaning work.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
