Description

Technical Field

[0001] This utility model relates to the field of food processing machinery, and in particular to a Jerusalem artichoke peeling and cleaning machine based on a flexible brush. Background Technology

[0002] Jerusalem artichokes, as a tuberous crop with irregular skin and a lot of attached mud and sand, present many technical challenges for mechanized peeling and cleaning. In existing technologies, traditional peeling equipment mostly uses hard friction rollers or blade structures. Although they can remove the skin, they are prone to causing scratches and high damage rates on the surface of Jerusalem artichokes. This is especially true for organically grown Jerusalem artichokes, where the integrity of the skin directly affects their commercial value.

[0003] In the cleaning process, conventional spraying devices, due to their fixed water flow direction and insufficient coverage, are ineffective at removing residual mud and sand from depressions. Simultaneously, the lack of coordination between the material conveying mechanism and the cleaning components easily leads to accumulation or cleaning blind spots. Furthermore, mud and sand separation systems generally suffer from low separation efficiency and incomplete slag removal, causing a rapid increase in circulating water turbidity, affecting cleaning effectiveness and increasing water consumption. These technical deficiencies restrict the improvement of processing efficiency, necessitating a specialized device that combines gentle peeling, efficient cleaning, and intelligent slag removal.

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a Jerusalem artichoke peeling and cleaning machine based on a flexible brush.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a Jerusalem artichoke peeling and washing machine based on flexible brushes, comprising: a washing tank with an upwardly inclined feeding channel at the inlet end and a downwardly inclined discharge channel at the outlet end, wherein an adjustable baffle is provided at the end of the discharge channel; a peeling assembly comprising multiple parallel spiral rollers and a peeling roller with flexible bristles on its surface, wherein the spiral rollers and the peeling roller are staggered along the length of the washing tank, the surface of the spiral rollers is provided with continuous spiral ridges, and the flexible bristles of the peeling roller are distributed in bundles with gaps between adjacent bundles; a driving mechanism that drives the spiral rollers to rotate forward at a first speed and the peeling rollers to rotate in reverse at a second speed higher than the first speed through gear linkage; a spraying assembly comprising multiple spray heads distributed along the length of the washing tank, wherein the water outlet direction of each spray head is inclined towards the root of the bristles of the peeling roller; and a silt separation assembly comprising a separation cylinder, a centrifugal mechanism, and a collection bin, wherein the inner side of the separation cylinder is provided with spiral guide blades with gradually decreasing pitch, and the bottom of the collection bin is provided with an automatic slag discharge valve triggered by a sensor.

[0007] As a preferred embodiment of this utility model, the flexible bristles of the peeling roller are connected to the roller shaft through an elastic connector, the elastic connector including an elastic displacement part for radial buffering and a rigid limiting part for limiting axial displacement.

[0008] As a preferred technical solution of this utility model, the top of the spiral ridge of the spiral roller is embedded with an elastic anti-slip layer, and the surface of the elastic anti-slip layer is provided with a number of evenly distributed protruding particles, the density of the protruding particles gradually increases from the middle of the spiral roller to both ends.

[0009] As a preferred embodiment of this utility model, the gear set includes a speed-changing mechanism with an adjustable transmission ratio, and the speed-changing mechanism is connected to both the peeling roller and the spiral roller in a transmission connection.

[0010] As a preferred technical solution of this utility model, the separation cylinder of the mud and sand separation component is provided with filter holes on the cylinder wall, the spiral guide blade is coaxially arranged with the separation cylinder and driven to rotate by the centrifugal mechanism, and the automatic slag discharge valve of the collection bin is opened when the mud and sand accumulate to a set thickness.

[0011] As a preferred embodiment of this utility model, the spray head is connected to the water supply pipe through an adjustable connector, and the water outlet direction of the spray head forms an acute angle with the tangent direction of the peeling roller rotation direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The design combines bundled flexible bristles with elastic connectors. Through radial buffering, it adapts to the uneven surface of Jerusalem artichokes, maintaining constant contact pressure while reducing the skin damage rate to below 3%. It is especially suitable for processing high-value organic Jerusalem artichokes.

[0014] 2. The differential speed drive of the spiral roller and the peeling roller creates a turbulent cleaning field, which, combined with the directional pushing of the spiral ridges, increases the tumbling frequency of Jerusalem artichokes by 2 times, achieving a surface cleaning coverage rate of >95%;

[0015] 3. The directional spray system uses sharp angles to scrub the roots of the brush bristles, effectively removing mud and sand from the gaps between the bristle bundles. While saving 25% of water, the mud and sand removal rate is increased by 40%. The intelligent slag discharge system triggers the slag discharge valve through thickness sensing, achieving a mud and sand separation efficiency of 98% and avoiding pipe blockage and water pollution.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] like Figure 1-6 As shown, this utility model provides a Jerusalem artichoke peeling and washing machine based on a flexible brush, the main components and connection methods of which are as follows:

[0027] The washing tank 1 has an overall elongated trough structure, with an upwardly inclined feeding channel 11 at the inlet end and a downwardly inclined discharge channel 12 at the outlet end. A detachable and adjustable baffle 121 is located at the end of the discharge channel 12, and the material discharge speed is controlled by adjusting the opening angle of the baffle 121. A guide slope is provided at the bottom of the washing tank 1, allowing water and sediment to naturally converge at the slag discharge port.

[0028] Please see the appendix Figure 3The peeling assembly 2 includes alternating spiral rollers 21 and peeling rollers 22. The surface of the spiral rollers 21 is machined with continuous spiral ridges 211, with an elastic anti-slip layer 212 embedded at the top of each ridge. The surface of the anti-slip layer 212 is distributed with raised particles 213, the particle density of which gradually changes along the roller's axial direction. The peeling rollers 22 have bundles of flexible bristles 221 uniformly fixed circumferentially. The bristles 221 are connected to the roller shaft via an elastic connector 222, which consists of a radial buffer plate and an axial limiting sleeve. The spacing between the bristle bundles of adjacent peeling rollers 22 is 1 / 2 to 1 / 3 of the pitch of the spiral rollers 21.

[0029] The drive mechanism 23 controls the spiral roller 21 and the peeling roller 22 in conjunction with the gear set 24. The gear set 24 includes a driving gear, a driven gear, and a speed-changing gearbox. The output end of the speed-changing gearbox is connected to the spiral roller 21 and the peeling roller 22 respectively, so that the spiral roller 21 rotates forward at a first speed to convey materials, and the peeling roller 22 rotates in the opposite direction at a second speed, which is 2-3 times the first speed. The speed-changing mechanism of the gear set 24 supports manual or electric speed adjustment.

[0030] Please see the appendix Figure 2 Multiple spray heads 31 of the spray assembly 3 are distributed at intervals along the length of the cleaning tank 1. The spray heads 31 are connected to the main water supply pipe through universal connecting pipes. The water outlet direction of each spray head 31 is inclined towards the root area of ​​the bristles of the peeling roller 22. The spray angle is adjustable from 30 to 60°. The spray coverage area coincides with the rotation trajectory of the peeling roller 22.

[0031] Please see the appendix Figure 4 The separation cylinder 41 of the sediment separation component 4 is a cylindrical screen structure with multiple layers of filter holes on the cylinder wall. Inside the separation cylinder 41, a spiral guide vane 42 with a gradually decreasing pitch is coaxially mounted, and the spiral guide vane 42 is driven to rotate by a centrifugal mechanism 43. A conical collection chamber 44 is located below the separation cylinder 41, and an automatic slag discharge valve 45 controlled by a thickness sensor is installed at the bottom of the collection chamber 44. The rotation axis of the centrifugal mechanism 43 coincides with the central axis of the separation cylinder 41.

[0032] The method of using this utility model is as follows:

[0033] 1. After the material enters the washing tank 1 through the feeding channel 11, the spiral roller 21 pushes the material forward through the spiral protrusion 211. At the same time, the peeling roller 22 rotates in the opposite direction at high speed. The flexible bristles 221 and the spiral protrusion 211 form an interlaced shearing action to peel off the skin and agitate the water flow.

[0034] 2. The spray head 31 continuously washes away the mud and sand carried away by the bristles. The sewage enters the separation cylinder 41 through the guide slope. When the spiral guide blade 42 rotates, it generates centrifugal force to achieve mud-water separation.

[0035] 3. The purified water flows back to the cleaning tank 1 for recycling, and the sediment is discharged through the automatic sludge discharge valve 45 when the sediment accumulates to a set thickness.

[0036] This utility model is a Jerusalem artichoke peeling and cleaning machine based on a flexible brush. Through multi-dimensional collaborative innovation, it achieves a breakthrough in the efficiency of the cleaning and peeling process while ensuring a low damage rate (skin breakage rate <3%). It saves more than 40% energy compared to traditional equipment and is particularly suitable for high-value-added organic Jerusalem artichoke processing scenarios.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
