Description

Technical Field

[0001] This utility model relates to the technical field of onion cleaning equipment, specifically a cleaning device for onion processing. Background Technology

[0002] Cleaning is a crucial step in onion processing to ensure product quality and safety. Traditional onion cleaning methods rely heavily on manual scrubbing or simple mechanical rinsing, which are inefficient, labor-intensive, and wasteful of water resources.

[0003] With the increasing demand for large-scale planting and processing, the existing cleaning equipment has gradually revealed the following defects: First, spray cleaning machines have a simple structural design and a limited spray range, making it difficult for water to fully cover the surface of onions, especially leaving soil and dirt adhering to the surface. Second, bubble or soaking cleaning machines rely on a static water environment and lack physical scrubbing action, making it impossible to effectively remove stubborn stains from the onion skin. At the same time, they consume a lot of water and have a low wastewater recycling rate, resulting in serious waste of water resources.

[0004] In summary, there is an urgent need to design an onion processing and cleaning device to solve the above problems. Utility Model Content

[0005] This utility model relates to a cleaning device for onion processing, aiming to solve many shortcomings of existing cleaning equipment. Specifically, existing spray-type cleaning machines have a relatively simple structural design and limited spray range, making it difficult for water to fully cover the surface of onions, especially leaving soil and dirt adhering to the surface. On the other hand, bubble or soaking cleaning machines rely on a static water environment and lack physical scrubbing action, failing to effectively remove stubborn stains from the onion skin. At the same time, they consume a lot of water and have a low wastewater recycling rate, resulting in serious water waste.

[0006] This utility model provides an improved solution to the above problems:

[0007] A cleaning device for onion processing includes two side plates, with a plurality of rotating rollers rotatably connected between the two side plates. A plurality of conveying mechanisms are spaced apart along the axial direction on the rotating rollers. A cleaning mechanism is arranged above each conveying mechanism. One end of a rotating roller near the front end of the side plate passes through the side plate and is connected to the output end of a gearbox fixed to the outer wall of the side plate. The input end of the gearbox is fixedly connected to the output shaft of a drive motor.

[0008] Specifically, the conveying mechanism includes several pulleys fixedly installed on the rotating rollers, a conveyor belt sleeved on the pulleys, and several through holes evenly opened on the conveyor belt;

[0009] Specifically, the cleaning mechanism includes cleaning rollers located above both sides of the conveyor belt. The two ends of the cleaning rollers are rotatably connected to a front baffle and a rear baffle, respectively. The front baffle and the rear baffle are fixedly connected to the front end and the rear end of the side plate, respectively. Both the front baffle and the rear baffle have material passage slots spaced apart. A conical guide plate is fixedly connected between two adjacent material passage slots of the front baffle. A hopper is fixedly connected to the front end of the side plate. A mounting plate is fixedly connected to one side of the rear baffle. One end of each of the two cleaning rollers between two adjacent conveyor belts passes through the rear baffle and the mounting plate and is fixedly connected to meshing gears. A sprocket is fixedly connected to the end shaft of the cleaning roller on one side of the gear. Multiple sprockets are connected by chain drive. A driven sprocket is fixedly connected to the side of the outermost sprocket. The driven sprocket is connected to a drive sprocket by a drive chain drive. The drive sprocket is fixedly mounted on the output shaft of the commutator. The input shaft of the commutator is fixedly connected to the end of the roller away from the drive motor.

[0010] Furthermore, each of the conveyor belts is provided with a water spray pipe above it, and a row of nozzles is installed on the pipe wall. The two ends of the water spray pipe are fixed to the upper ends of the front baffle and the rear baffle respectively by brackets, and one end of the water spray pipe is connected to the water supply pipe.

[0011] Furthermore, the width of the material passage trough is matched with the width of the conveyor belt.

[0012] Furthermore, the upper side of the chain is provided with several tensioning wheels that are rotatably connected to the mounting plate.

[0013] Furthermore, the hopper is inclined relative to the horizontal plane at an angle of 30°-45°.

[0014] Furthermore, the commutator is fixedly connected to the outer wall of the side plate, and the nozzle is set vertically downward.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This onion processing cleaning device uses rotating cleaning rollers installed on both sides of the conveyor belt, combined with a synchronous transmission design of gears and chains, to ensure that the onions are brushed in multiple directions during the conveying process. This effectively removes the soil and dirt sticking to the surface of the onions, solving the problem of insufficient water coverage in traditional spray-type cleaning machines. Secondly, the vertically downward spray nozzles of the water pipe work together with the cleaning rollers to form a composite cleaning mode of "water flushing + physical brushing", which can efficiently remove stubborn dirt and avoid cleaning blind spots caused by static soaking.

[0017] 2. This onion processing cleaning device achieves rapid discharge of cleaning wastewater by uniformly opening through holes in the conveyor belt and coordinating with spray water flow, reducing water accumulation. At the same time, the spray water pressure is controllable, which greatly reduces water consumption compared with soaking cleaning.

[0018] 3. This onion processing cleaning device uses a drive motor to drive rotating rollers via a gearbox, and simultaneously links them to a cleaning brush via a commutator, achieving synchronous control of conveying and cleaning, reducing manual intervention. Furthermore, multiple conveyor belts are arranged in parallel, working with conical guide plates to guide the onions, enabling continuous feeding and unloading. Attached Figure Description

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.

[0029] Please see Figure 1-8 A cleaning device for onion processing includes two side plates 1, with a plurality of rotating rollers 2 rotatably connected between the two side plates 1. A plurality of conveying mechanisms 3 are arranged axially on the rotating rollers 2, and a cleaning mechanism 4 is arranged above each conveying mechanism 3. One end of a rotating roller 2 near the front end of the side plate 1 passes through the side plate 1 and is connected to the output end of a gearbox 5 fixed to the outer wall of the side plate 1. The input end of the gearbox 5 is fixedly connected to the output shaft of a drive motor 6.

[0030] The conveying mechanism 3 includes several pulleys 301 fixedly installed on the roller 2, a conveyor belt 302 sleeved on the pulleys 301, and several through holes 303 evenly opened on the conveyor belt 302;

[0031] The cleaning mechanism 4 includes cleaning roller brushes 401 located above both sides of the conveyor belt 302. The two ends of the cleaning roller brushes 401 are rotatably connected to the front baffle 402 and the rear baffle 403, respectively. The front baffle 402 and the rear baffle 403 are fixedly connected to the front and rear ends of the side plate 1, respectively. Material passage grooves 4021 are spaced apart on both the front baffle 402 and the rear baffle 403. A conical guide plate 412 is fixedly connected between two adjacent material passage grooves 4021 of the front baffle 402. A hopper 404 is fixedly connected to the front end of the side plate 1. A mounting plate 405 is fixedly connected to one side of the rear baffle 403. Between two adjacent conveyor belts 302... Two cleaning roller brushes 401 have one end passing through the rear baffle 403 and the mounting plate 405, and are fixedly connected to meshing gears 413. One side of the gears 413 is provided with a sprocket 406 fixedly connected to the end shaft of the cleaning roller brushes 401. Multiple sprockets 406 are connected by a chain 407. The outermost sprocket 406 is fixedly connected to a driven sprocket 408. The driven sprocket 408 is connected to a drive sprocket 410 by a drive chain 409. The drive sprocket 410 is fixedly mounted on the output shaft of the commutator 411. The input shaft of the commutator 411 is fixedly connected to one end of the roller 2 away from the drive motor 6.

[0032] Each conveyor belt 302 is equipped with a water spray pipe 7 above it. A row of nozzles 701 are installed on the pipe wall of the water spray pipe 7. Both ends of the water spray pipe 7 are fixed to the upper ends of the front baffle 402 and the rear baffle 403 respectively via brackets 8. One end of the water spray pipe 7 is connected to a water supply pipe 9. It should be noted that the water supply pipe 9 can be connected to a tap water pipe or a water pump for water supply. The water supply pipe 9 is equipped with a solenoid valve to control the water supply volume.

[0033] The width of the material passage trough 4021 is matched with the width of the conveyor belt 302.

[0034] The chain 407 has several tension wheels 10 rotatably connected to the mounting plate 405 on its upper side. The tension wheels 10 prevent the chain 407 from skipping teeth or falling off.

[0035] The hopper 404 is inclined relative to the horizontal plane at an angle of 30°-45°.

[0036] The commutator 411 is fixedly connected to the outer wall of the side plate 1, and the nozzle 701 is set vertically downward.

[0037] Working principle: During use, the drive motor 6 is started, driving the roller 2 to rotate and the pulley 301 fixedly connected to it to rotate. The rotating pulley 301 drives the conveyor belt 302 sleeved on it to rotate. At this time, the onions poured into the hopper 404 are distributed by the conical guide plate 412, pass through the material passage 4021, and roll onto the upper surface of the conveyor belt 302. As the conveyor belt 302 moves towards the rear baffle 403, the roller 2 transmits power through the reversing device 411 to drive the drive sprocket 410 to rotate. The drive sprocket 410 then drives the driven sprocket 408 to rotate through the drive chain 409. The rotating driven sprocket 408 drives the sprocket 406 and the cleaning roller brush 401 fixedly connected to it to rotate. This, in turn, drives the remaining sprocket 408 to rotate synchronously through the chain 407, thereby driving the sprocket 406 and the cleaning roller brush 401 to rotate. The fixedly connected cleaning rollers 401 rotate, and the rotating cleaning rollers 401, in turn, drive another meshing gear 413 to rotate through their fixedly connected gears 413. At this time, all the cleaning rollers 401 are rotating, and then water is sprayed through the water supply pipe 9 to the water spray pipe 7, causing the nozzle 701 to spray water downwards. The water flows onto the surface of the onion to soften the sticky soil and dirt. At the same time, while the onion is being conveyed on the conveyor belt 302, its surface is also being scrubbed by the rotating cleaning rollers 401 on both sides above the conveyor belt 302. As the onion is conveyed forward by the conveyor belt 302, it will also tumble under the scrubbing action of the cleaning rollers 401. Therefore, the surface of the onion is fully covered by water and scrubbed, ensuring that all the sticky soil and dirt on the surface of the onion are completely cleaned. At the same time, the water spraying from the nozzles saves water compared to the previous soaking cleaning. Finally, the cleaned onion will fall from the end of the conveyor belt 302 near the rear baffle 403 after passing through the material passage chute 4021.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
