Description

Technical Field

[0001] The present invention relates to the field of conveying devices, in particular to a granular fragrance conveying device. Background Art

[0002] During the production of Sichuan peppercorn spice, after being cleaned, the peppercorn granules are transported from bottom to top via a Z-shaped conveyor belt (elevating conveyor belt) to the top of a drying tower where they are then dried. The surface of the cleaned peppercorns is moist, and the skin contains volatile oils, which reduces friction with the conveyor belt. During the inclined conveying process, the peppercorns are prone to sliding downward along the slope. To prevent the peppercorns from sliding, horizontal baffles are usually installed on the conveyor belt. However, this method still has certain drawbacks: Under the influence of the inclination angle, the pepper particles tend to slide downward along the conveying surface and accumulate on the baffle. The stickiness will cause some particles to stick to each other to form small clumps. In addition, due to the wide-top and narrow-bottom material guide design of the feed hopper, the initial landing point of the pepper will be in the middle of the conveyor belt. Therefore, there are more pepper particles in the middle area than on both sides, causing the particles and clumps in the middle to scatter to both sides, forming a triangular accumulation with a high middle and low sides.

[0003] The surface of the conveyor belt in the low accumulation areas on both sides is exposed to a large amount, and the wet conveyor belt is prone to direct adhesion of scattered fine particles; the high accumulation area in the middle will cause excessive local pressure, causing the lumps to be in close contact with the conveyor belt. The mucus formed by the mixture of oil and water on the surface of the pepper particles will firmly adhere to the surface of the conveyor belt, forming a complex pollution of bottom adhesion and surface accumulation. In addition, the pepper particles that are under excessive local pressure are easy to break, and the broken pepper is more likely to adhere. These adhesions gradually harden during the transportation process and need to be stopped and scraped off regularly, which not only affects production continuity, but also may damage the surface of the conveyor belt due to hard scraping, aggravating subsequent adhesion. In addition, when these triangular accumulations are transported to the feed inlet of the drying tower, the uneven distribution will cause the material entering the drying tower to be thick in the middle and thin on both sides, affecting the uniformity of heating during drying. Summary of the Invention

[0004] In view of the problem in the above or prior art that peppercorn particles easily form a triangular pile with a high middle and low sides at the conveyor belt baffle, the present invention is proposed.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 7 The present embodiment provides a granular spice conveying device, which can achieve a uniform distribution effect of peppercorns on a conveyor belt, comprising a lifting conveyor line 1 consisting of a frame 11 and a baffle conveyor belt 12, wherein a cover body 2 is fixedly mounted on the frame 11 and is arranged on the outside of the baffle conveyor belt 12, and a track material-splitting unit 4 is provided between the cover body 2 and the baffle conveyor belt 12; the track material-splitting unit 4 comprises a material-splitting assembly 41 for cooperating with the baffle conveyor belt 12 to convey the peppercorns in an oblique track; a control assembly 42 for controlling the material-splitting assembly 41 to approach the peppercorns and a traction assembly 43 for pulling the material-splitting assembly 41 to move the peppercorns after approaching the peppercorns are provided between the material-splitting assembly 41 and the cover body 2; Reference Figures 2 to 7 The track material leveling unit 4 also includes a reset component 44 arranged in the moving stroke of the material-dispensing component 41 along the conveying direction of the pepper. The reset component 44 is used to trigger the reset of the material-dispensing component 41, the control component 42 and the traction component 43. A feed hopper 3 is fixedly mounted on the cover body 2, and the feed hopper 3 is located at the pepper feeding end.

[0028] It should be noted that the lifting conveyor line 1 is a conveying device for inclined lifting materials. Specifically, it can be composed of a belt conveyor with baffles, and the baffles are arranged at intervals to prevent the pepper particles from sliding down; the cover body 2 is a protective structure covering the conveyor belt, which can be made of metal plates or plastic plates to prevent particles from splashing and forming a closed space.

[0029] The feed hopper 3 is a funnel-shaped structure with a material guiding function, and can be specifically a conical metal shell that is wide at the top and narrow at the bottom, with its bottom opening aligned with the feed end of the baffle conveyor belt 12 .

[0030] Located at the pepper feeding end means that the outlet end of the feed hopper 3 is connected with the starting conveying position of the baffle conveyor belt 12. Specifically, the bottom of the feed hopper 3 can be fixed to the side wall of the cover body 2 above the starting end of the baffle conveyor belt 12 by welding or bolting.

[0031] Reference Figures 2 to 7 The control component 42, the traction component 43 and the reset component 44 are all arranged in two symmetrical groups along the conveying direction of the pepper. The material-selecting component 41 includes several support plates 411 fixedly mounted on the inner wall of the cover body 2. A reset spring 412 is fixedly mounted on the side of the support plate 411 away from the baffle conveyor belt 12, and a mounting plate 413 is commonly mounted on the ends of the several reset springs 412.

[0032] It should be noted that the support plate 411 is a load-bearing structure fixed to the inner wall of the cover body 2, and can be fixed by steel plate welding or bolt connection. Its function is to provide an installation basis for the reset spring 412 and transmit elastic force. The reset spring 412 is an elastic element connecting the support plate 411 and the mounting plate 413, and can be specifically a coil spring or a leaf spring.

[0033] Reference Figures 3 to 7 The mounting plate 413 is provided with a plurality of slide grooves 414 perpendicular to the conveying direction of the pepper, and a slide rod 415 is slidably installed in the slide groove 414. A dial plate 417 is fixedly installed on one end of the slide rod 415 near the baffle conveyor belt 12.

[0034] It should be noted that the slide groove 414 is a guide structure arranged on the mounting plate 413, which is used to constrain the moving trajectory of the slide rod 415. The slide rod 415 is a rigid component that moves laterally along the slide groove 414, and can specifically be a metal round rod or a square rod. The dial plate 417 connected to the end of the slide rod 415 is used to contact the pepper particles; the dial plate 417 is a component that directly interacts with the pepper, and can specifically be a plastic plate or rubber plate with a smooth surface.

[0035] Reference Figures 3 to 7 The outer fixed sleeve of the slide rod 415 is provided with a plurality of limiting sleeves 416 , and the limiting sleeves 416 are slidably connected to the mounting plate 413 .

[0036] It should be noted that the limiting sleeve 416 is an annular structure fixed to the outside of the sliding rod 415 and is used to limit the vertical position of the sliding rod 415. Specifically, a sleeve made of metal or plastic can be used.

[0037] Reference Figures 3 to 7 A plurality of fixing plates 418 are fixedly installed on the side of the mounting plate 413 away from the baffle conveyor belt 12, and a connecting plate 419 is fixedly installed on the end of the slide rod 415 away from the baffle conveyor belt 12, and a return spring 2 410 is installed between the connecting plate 419 and the fixing plate 418.

[0038] It should be noted that the fixed plate 418 is a plate-like structure fixedly connected to the mounting plate 413, which can be specifically fixed by metal plate welding or bolts, and is used to provide an installation basis for the reset spring 2 410. The reset spring 2 410 is an elastic element connecting the fixed plate 418 and the connecting plate 419, which can specifically be a coil spring or a leaf spring, and is used to provide a reverse force after the slide rod 415 moves to facilitate reset.

[0039] The slide bar 415 guides the slide groove 414 in a transverse direction, so that the paddle plate 417 can move perpendicular to the conveying direction. When the peppercorns form a triangular pile in the middle of the baffle conveyor belt 12 (such as Figure 2 and Figure 3 As shown in the figure, the paddle 417 moves the prickly ash material shifting assembly 41 along an oblique trajectory. Regarding the explanation of the oblique trajectory, the oblique motion trajectory includes both lateral movements to both sides of the conveyor belt and longitudinal movements close to the surface of the conveyor belt, thereby forming an oblique motion trajectory. Through this oblique composite motion, the prickly ash particles piled up in a triangular shape (high in the middle and low on both sides) at the baffle are exactly matched, and the prickly ash particles are accurately spread out from the middle of the thickest pile to both sides, thereby achieving uniform distribution of the prickly ash on the conveyor belt.

[0040] During specific use, when the baffle moves with the conveyor belt to the control component 42, the baffle will squeeze the control component 42 to drive the mounting plate 413 close to the conveyor belt surface. At the same time, the movement of the mounting plate 413 drives the slide bar 415 and the paddle plate 417 to approach the conveyor belt surface synchronously, so that the paddle plate 417 can accurately contact the pepper particles piled up in a triangular shape at the baffle. In this process, there will be no pepper particles in the part between the two adjacent baffles away from the ground due to gravity sliding. Therefore, the paddle plate 417 will not contact the pepper particles when approaching the conveyor belt surface, thereby achieving precise matching of the material paddle component 41 and the conveying rhythm, ensuring that intervention can be formed at the position where the pepper particles are accumulated, avoiding premature or late action to affect the material leveling effect.

[0041] When the baffle approaches the Sichuan peppercorns, its continued movement drives the traction assembly 43 to pull the paddle plate 417, which then performs a paddle movement. The movement of the slider 415 directly drives the paddle plate 417 toward the sides of the conveyor belt. Combined with the previous longitudinal movement toward the conveyor belt, this creates a diagonal composite trajectory that perfectly matches the triangular shape of the paddle grains, extending from the center, where the paddle grains are highest, downward to either side. This effectively disperses any excess paddle grains in the center, breaking the sticky bonds between the paddle grains and achieving even distribution of the paddle grains on the conveyor belt.

[0042] Reference Figures 3 to 7 The control component 42 includes an I-shaped frame 421 fixedly mounted on the inner wall of the cover body 2, a slide rail 422 is fixedly mounted on the side of the I-shaped frame 421 away from the feed end, a sliding plate 423 is slidably mounted in the slide rail 422, a movable plate 424 slides through the sliding plate 423, an abutment plate 425 is fixedly mounted on the side of the movable plate 424 close to the feed end, and a control plate 426 is fixedly mounted on the side of the movable plate 424 away from the feed end.

[0043] It should be noted that the sliding plate 423 is configured as a retractable telescopic plate, and the portion that is slidably connected to the slide rail 422 is a fixed section of the telescopic plate.

[0044] Reference Figures 3 to 7 A squeeze plate 427 is fixedly mounted on the side of the control plate 426 away from the feed end, and a pressure rod 428 is fixedly mounted on the side of the mounting plate 413 close to the baffle conveyor belt 12. The pressure rod 428 is provided with a slope that matches the squeeze plate 427.

[0045] It should be noted that the I-frame 421 is a supporting structure with an I-shaped cross-section, which can be formed by welding or casting metal profiles, and is used to provide a stable installation base for the slide rail 422. The slide rail 422 is a guide component extending along the direction of pepper transportation, and can specifically adopt a linear guide rail with a ball or slide groove 414 to constrain the moving trajectory of the sliding plate 423; the sliding plate 423 is a load-bearing component that cooperates with the slide rail 422, and can specifically be made of steel plate.

[0046] The extrusion plate 427 is a plate-like structure fixed to the end of the control plate 426, which can be specifically formed by stamping a metal plate, and is used to contact the slope of the pressure rod 428 and apply thrust during movement; the pressure rod 428 is a rod-shaped component installed on the mounting plate 413, which can be specifically formed by processing a square metal rod, and the slope set at its end is an inclined surface, which is used to convert the horizontal thrust of the extrusion plate 427 into the vertical displacement of the mounting plate 413; the slope is the inclined surface where the end of the pressure rod 428 contacts the extrusion plate 427.

[0047] During specific use, when the baffle moves with the conveyor belt to the abutment plate 425, it will come into contact with the abutment plate 425 and apply a thrust. Since the abutment plate 425 is fixed on the moving plate 424, this thrust will drive the moving plate 424 to move along the penetration direction of the sliding plate 423, thereby driving the control plate 426 and the extrusion plate 427 to move synchronously. When the extrusion plate 427 moves with the control plate 426 to contact the pressure rod 428, the control component 42 enters the force conversion stage, and the continuous forward movement of the extrusion plate 427 will apply a horizontal thrust along the slope of the pressure rod 428; with the help of the inclined characteristics of the slope, this horizontal force is decomposed into a component force perpendicular to the direction of the conveyor belt, pushing the pressure rod 428 to drive the mounting plate 413 to move in the direction close to the conveyor belt and compress the return spring 412, thereby driving the shift plate 417 close to the conveyor belt.

[0048] Reference Figures 3 to 7 The traction assembly 43 includes two fixed pulleys 431 fixedly mounted on the I-frame 421, a traction rope 432 is wound around the outside of the two fixed pulleys 431, a traction plate 433 is fixedly mounted on the outside of the slide rod 415, and both ends of the traction rope 432 are fixedly connected to the sliding plate 423 and the traction plate 433 respectively.

[0049] It should be noted that the fixed pulley 431 is a grooved wheel with a fixed axis that can rotate around its own axis. It can be made of metal or high-strength plastic. It is used to change the direction of the force applied by the traction rope 432 to achieve power transmission. The traction rope 432 is a rope with tensile strength. It can be made of steel wire rope or synthetic fiber rope. It is used to connect the sliding plate 423 and the traction plate 433. The traction plate 433 is a plate-like structure fixedly connected to the slide bar 415. It is used to transmit the tension of the traction rope 432 to the slide bar 415, driving the paddle plate 417 to move laterally. During specific use, when the shift plate 417 approaches the conveyor belt, the abutment plate 425 collides with the sliding plate 423, and then the baffle continues to push the abutment plate 425 to drive the sliding plate 423 to slide along the slide rail 422, so that the sliding plate 423 pulls one end of the traction rope 432. The direction of the pulling force will be converted into pulling the traction plate 433 under the action of the fixed pulley 431, driving the slide rod 415 to move along the slide groove 414 on the mounting plate 413, thereby driving the shift plate 417 to shift the pepper particles.

[0050] Reference Figures 3 to 7 The reset assembly 44 includes a wedge block 441 fixedly mounted on the sliding plate 423 near the inner wall of the cover body 2, a fixing rod 442 fixedly mounted on the inner wall of the cover body 2, and a wedge block 443 matched with the wedge block 441 fixedly mounted at the end of the fixing rod 442.

[0051] It should be noted that wedge block 1 441 is fixedly installed on the outside of the telescopic section of the sliding plate 423. Wedge block 1 441 is a block structure with an inclined contact surface. Specifically, it can be formed by metal or high-strength plastic. Its inclined surface forms a sliding fit with the inclined surface of wedge block 2 443. When the sliding plate 423 moves to the position of the fixed rod 442 during the conveying process, wedge block 1 441 and wedge block 2 443 produce lateral displacement through the contact of the inclined surface, thereby pushing the sliding plate 423 to reset.

[0052] The fixing rod 442 is a supporting structure fixed to the inner wall of the cover body 2, which can be fixed by bolts or welding, and is used to provide support for the wedge block 2 443; the wedge block 2 443 is a block structure with a complementary shape to the wedge block 1 441, and its inclination angle matches that of the wedge block 1 441.

[0053] In specific use, when the baffle pushes the sliding plate 423 along the slide rail 422 to the position of the reset assembly 44, the wedge block 1 441 fixed to the sliding plate 423 gradually approaches the wedge block 2 443. As the sliding plate 423 continues to advance, the inclined surface of the wedge block 1 441 comes into contact with the inclined surface of the wedge block 2 443, and they squeeze each other. This squeezing action generates a component force perpendicular to the direction of movement, pushing the telescopic section of the sliding plate 423 upward, causing the abutment plate 425 to gradually separate from the baffle. At this point, the baffle's thrust on the moving plate 424 disappears, and the control assembly 42 and the traction assembly 43 lose their external driving force. Then the return spring 2 410 pulls the connecting plate 419, driving the slide bar 415 to reset, thereby driving the dial plate 417 to reset. At the same time, the sliding plate 423 slides and resets along the slide rail 422 under the action of gravity, and the moving plate 424 will also reset under the action of gravity. When the sliding plate 423 completes its reset, the inclined surface of the squeezing plate 427 contacts the inclined surface of the pressure rod 428. At this time, the return spring 1 412 will also reset, driving the mounting plate 413 to move and reset to the side away from the baffle conveyor belt 12, thereby also playing a role in assisting in pushing the squeezing plate 427 and driving the moving plate 424 to reset. Afterwards, as the next baffle of the baffle conveyor belt 12 squeezes the abutment plate 425 again, the above-mentioned material leveling operation can be repeated to achieve continuous operation.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
