[0027] Compared with the prior art, the present application has the beneficial effects that:

[0028] Firstly, the sweet potatoes are placed on the roller shaft at the input position, and at the same time, the first motor and the vibrator are started: the main synchronous belt is moved by the first motor to move the roller shaft, the roller shaft rotates due to the contact of the roller and the upper surface of the side plate, and the distance between the adjacent two roller shafts is very small, so the rotation of the roller shaft drags the sweet potatoes forward, and since the sweet potatoes are generally in the shape of a cylinder, the sweet potatoes also rotate when moving, and it should be noted that the moving speed of the main synchronous belt is slow, so the sweet potatoes slowly move forward while rotating and vibrating, and the technical advantages are that:

[0029] 1. The vibration can make the soil on the surface of the sweet potatoes be shaken off, so as to avoid the soil being adhered due to water during subsequent cleaning, and to affect the cleaning effect; 2. If the roller shaft only drags the sweet potatoes forward without rotating, the sweet potatoes only move to the cleaning position, and the contact position of the sweet potatoes and the roller shaft does not change when the sweet potatoes are vibrated, so that the soil at the contact position is pressed and hardened during continuous up-down vibration, which affects the subsequent cleaning effect. In the present application, the sweet potatoes can slowly move forward while rotating, so this problem does not exist, and further, the rotation of the sweet potatoes can also have a shaking effect, so that the soil can be separated more quickly. If the sweet potatoes do not rotate, the soil on the top of the sweet potatoes and the soil at the contact position of the sweet potatoes and the roller shaft is difficult to shake off;

[0030] Secondly, the sweet potatoes are washed by the cleaning member at the cleaning position;

[0031] The rollers on the roller shaft at the cleaning position are in contact with the lower synchronous belt and the upper synchronous belt, so the rotation speed of the roller shaft is controllable and adjustable, and the rotation speed of the sweet potatoes also changes correspondingly. The sweet potatoes can rotate forward or backward at a high speed, and the rotatable nozzle of the cleaning member is also provided, so that an integrated scheme is constructed, and the technical advantages are that:

[0032] 1、When the soil of sweet potato is less, the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are the same, which can speed up the discharge of the sweet potato;

[0033] When the soil of sweet potato is more, the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are opposite, which can prolong the cleaning time of the sweet potato;

[0034] 2、The integrated cleaning structure has the following four cases: the nozzle does not rotate, and the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are the same; the nozzle rotates, and the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are the same; the nozzle does not rotate, and the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are opposite; the nozzle rotates, and the direction of the self-rotation of the roller shaft and the direction of the main synchronous belt are opposite;

[0035] The first case corresponds to light cleaning, the second and third cases correspond to medium cleaning, and the fourth case corresponds to heavy cleaning. The staff can choose different cleaning modes according to the dirtiness of the sweet potato;

[0036] Further, the two cases of the medium cleaning mode are as follows: when the amount of sweet potato is large and the coverage is wide, the second case can be used to speed up the cleaning efficiency; when the amount of sweet potato is small and the coverage is narrow, the second and third cases can be used;

[0037] 3、Further, during the cleaning process, the sweet potato is still subjected to vibration, which can also change the position of the sweet potato slightly, thereby changing the position of the water flow sprayed on the sweet potato, thereby improving the cleaning effect;

[0038] III、After cleaning, the sweet potato enters the output position and is pulled away. Similar to the input position, the sweet potato can be subjected to vibration and rotation, which can speed up the draining of water on the surface of the sweet potato. BRIEF DESCRIPTION OF DRAWINGS

[0050] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0051] Reference Figures 1-8 A roller-type sweet potato washing machine includes a traction component 100 and a washing component 200.

[0052] Traction component 100:

[0053] Reference Figures 2-5 The traction component 100 includes a fixed bracket 101 and a traction groove shell 102 that is slidably connected to the fixed bracket 101 in the vertical direction, and a spring 103 is provided between the two. Furthermore, a vibrator 105 and a drainage convex pipe 104 are provided at the bottom of the traction groove shell 102. When the vibrator 105 is activated, it can drive the traction groove shell 102 to vibrate in the vertical direction.

[0054] The upper opening of the traction groove shell 102 is provided with a main synchronous belt 107, the conveying direction of the main synchronous belt 107 is parallel to the length direction of the traction groove shell 102, the main synchronous belt 107 is provided with two along the width direction of the traction groove shell 102, and the main synchronous belt 107 is driven to run by the first motor 106.

[0055] The two main synchronous belts 107 are provided with a roller shaft 108, further, the axis direction of the roller shaft 108 is parallel to the width direction of the traction groove shell 102, the two ends of the roller shaft 108 are respectively connected with the two main synchronous belts 107 in a movable mode, the main synchronous belt 107 moves together with the roller shaft 108, and the roller shaft 108 is arranged in an array along the extension direction of the main synchronous belt 107.

[0056] The side opposite to the two main synchronous belts 107 is respectively provided with a side plate 110, the extension direction of the side plate 110 is parallel to the length direction of the traction groove shell 102, the upper surface of the side plate 110 is provided with a notch 111 at the middle position, and the notch 111 penetrates to the two sides of the side plate 110 along the width direction of the traction groove shell 102.

[0057] The notch 111 is provided with a speed regulating assembly.

[0058] Specifically, referring to Figure 5 , the speed regulating assembly comprises a lower support 112 arranged at the hole bottom of the notch 111 and an upper support 113 located above the lower support 112.

[0059] The bottom of the upper support 113 is provided with a guide rod 114 arranged vertically, the guide rod 114 is provided with a fixing ring after penetrating through a guide hole arranged on the lower support 112, and the outer portion of the guide rod 114 is provided with a spring 115 located between the fixing ring and the lower support 112.

[0060] The upper support 113 is provided with an upper synchronous belt 117, and the lower support 112 is provided with a lower synchronous belt 116, and the conveying directions of the lower synchronous belt 116 and the upper synchronous belt 117 are parallel to the length direction of the traction groove shell 102.

[0061] Referring to Figure 3 , the end of the roller shaft 108 is provided with a roller 109, and the roller 109 is in contact with the upper surface of the side plate 110.

[0062] The upper surface of the lower synchronous belt 116 is flush with the upper surface of the side plate 110, so that the roller 109 of the roller shaft 108 located at the notch 111 is located between the upper synchronous belt 117 and the lower synchronous belt 116 and is in close contact under the elastic force of the spring 115.

[0063] The working process of the traction member 100, specifically:

[0064] The traction member 100 is used to move the sweet potatoes by the rollers 108. For the convenience of description, the position close to the feeding end of the main synchronous belt 107 is named as the input position, the position close to the discharging end of the main synchronous belt 107 is named as the output position, and the position of the gap 111 is named as the cleaning position.

[0065] Firstly, the sweet potatoes are placed on the rollers 108 at the input position, and at the same time, the first motor 106 and the vibrator 105 are started: the rollers 108 are moved by the main synchronous belt 107 moved by the first motor 106, and the rollers 108 rotate due to the contact of the rollers 109 with the upper surface of the side plate 110. Since the distance between the adjacent two rollers 108 is small, the rotation of the rollers 108 can move the sweet potatoes forward. Since the sweet potatoes are generally in the shape of a cylinder, the sweet potatoes also rotate when moving. It should be noted that the moving speed of the main synchronous belt 107 is slow, so the sweet potatoes rotate while slowly moving forward and are vibrated.

[0066] The technical advantages are as follows: 1. The vibration can make the soil on the surface of the sweet potatoes be shaken off, so as to avoid the soil being adhered to the sweet potatoes when being washed, which affects the cleaning effect; 2. If the rollers 108 only move the sweet potatoes forward without rotating, the sweet potatoes only move to the cleaning position, and the contact position between the sweet potatoes and the rollers 108 does not change when the sweet potatoes are vibrated. When the sweet potatoes are continuously vibrated up and down, the soil at the contact position is pressed and hardened, which affects the subsequent cleaning effect. In the present scheme, the sweet potatoes rotate while slowly moving forward, so this problem does not exist. Furthermore, the rotation of the sweet potatoes can also have a shaking effect, so that the soil can be separated more quickly. If the sweet potatoes do not rotate, the soil on the top of the sweet potatoes and the soil at the contact position between the sweet potatoes and the rollers is difficult to shake off.

[0067] Then, the sweet potatoes enter the cleaning position and are washed by the cleaning member 200.

[0068] The rollers 108 on the cleaning position are in contact with the lower synchronous belt 116 and the upper synchronous belt 117, so the rotation speed of the rollers 108 is controllable and adjustable, and the rotation speed of the sweet potatoes also changes correspondingly. The sweet potatoes can rotate forward or backward, and the rotatable nozzle 219 of the cleaning member 200 is also provided, so that an integrated scheme is constructed. The technical advantages are as follows:

[0069] 1. When the sweet potatoes have less soil, the direction in which the rollers 108 rotate to move the sweet potatoes is the same as the conveying direction of the main synchronous belt 107, which can accelerate the discharge of the sweet potatoes.

[0070] When the sweet potatoes have more soil, the direction in which the rollers 108 rotate to move the sweet potatoes is opposite to the conveying direction of the main synchronous belt 107, which can prolong the cleaning time of the sweet potatoes.

[0071] 2、The integrated cleaning structure of the present solution has the following four cases: the direction in which the roller shaft 108 rotates to pull the sweet potatoes and the direction in which the main synchronous belt 107 is transported are the same when the spray head 219 does not rotate; the direction in which the roller shaft 108 rotates to pull the sweet potatoes and the direction in which the main synchronous belt 107 is transported are the same when the spray head 219 rotates; the direction in which the roller shaft 108 rotates to pull the sweet potatoes and the direction in which the main synchronous belt 107 is transported are opposite when the spray head 219 does not rotate; the direction in which the roller shaft 108 rotates to pull the sweet potatoes and the direction in which the main synchronous belt 107 is transported are opposite when the spray head 219 rotates;

[0072] The first case corresponds to light cleaning, the second and third cases correspond to medium cleaning, and the fourth case corresponds to heavy cleaning. The staff can choose different cleaning modes according to the dirtiness of the sweet potatoes.

[0073] Further, the two cases of the medium cleaning mode are as follows: a large amount of sweet potatoes covers a wide area, so the second case can be used to speed up the cleaning efficiency; a small amount of sweet potatoes covers a narrow area, so the second and third cases can be used.

[0074] 3. Further, during the cleaning process, the sweet potatoes are still subjected to vibration, which can also change the position of the sweet potatoes by a small amount, thereby changing the position of the water flow sprayed onto the sweet potatoes, thereby improving the cleaning effect.

[0075] After cleaning, the sweet potatoes enter the output position and are pulled away. Similar to the input position, the sweet potatoes can be subjected to vibration and rotation, and the technical advantage is that it can speed up the draining of water on the surface of the sweet potatoes.

[0076] II. Cleaning component 200:

[0077] Referring to Figure 6 With Figure 8 , the cleaning component 200 includes a water pump 201 and a connecting bracket 205 located above the cleaning position.

[0078] The connecting bracket 205 is provided with a flushing unit, and the flushing unit is arrayed with three along the conveying direction of the main synchronous belt 107.

[0079] The flushing unit includes a flushing member, which includes a flushing shaft 218 in the shape of a hollow shaft and a spray head 219 arranged at the bottom of the flushing shaft 218. According to the width direction size of the traction groove shell 102, multiple flushing members of each flushing unit are arrayed along the width direction of the traction groove shell 102 to achieve full coverage and no dead angle cleaning from the width direction of the traction groove shell 102.

[0080] Among the three washing units, the washing shaft 218 of the middle washing unit is arranged vertically, and the washing shafts 218 of the remaining two washing units are arranged obliquely, and the distance between the two is increased from bottom to top.

[0081] The connecting support 205 is provided with a main pipe 204, and the main pipe 204 is connected with the upper end of the washing shaft 218 through a branch pipe 217. It should be noted that the branch pipe 217 is sleeved with the washing shaft 218 or connected through a rotary joint technology.

[0082] The connecting support 205 is provided with a second motor 220, and the second motor 220 is connected with all the washing shafts 218 through a power connecting piece, that is, the second motor 220 can drive the nozzle 219 to rotate.

[0083] Referring to Figure 6 With Figure 7 The water outlet of the water pump 201 is provided with a water pipe 202, and the water pipe 202 is connected with the main pipe 204 through a pressure regulating assembly 203. The technical advantage is that the pulse washing is realized through the pressure regulating assembly 203, and the cleaning effect of the sweet potatoes is improved.

[0084] Specifically, the pressure regulating assembly 203 includes a valve shell 206 and a cylinder shell 209. The bottom of the valve shell 206 is connected with the water pipe 202. The valve shell 206 is sleeved with a valve plug 207. The upper part of the valve plug 207 is provided with a spring three 208.

[0085] The cylinder shell 209 is coaxially provided with a tapered pipe 210. The hole diameter of the tapered pipe 210 is increased from bottom to top. The upper pipe opening of the tapered pipe 210 is coaxially connected with the inner wall of the cylinder shell 209. The lower pipe opening of the tapered pipe 210 is provided with a column pipe 211.

[0086] The cylinder shell 209 is coaxially provided with a circular ring plate 213. The lower pipe opening of the column pipe 211 is connected with the inner ring surface of the circular ring plate 213.

[0087] The surface of the tapered pipe 210 is provided with a plurality of connecting holes. The upper part of the tapered pipe 210 is provided with an upper one-way valve 212, which is used to make the water in the area between the tapered pipe 210 and the circular ring plate 213 flow into the upper area of the tapered pipe 210 through the connecting holes in one direction.

[0088] The lower part of the circular ring plate 213 is provided with a lower one-way valve 214, which is used to make the water in the column pipe 211 flow into the lower area of the circular ring plate 213 in one direction.

[0089] The upper one-way valve 212 and the lower one-way valve 214 can be realized by using the existing technology, and details are not described herein.

[0090] The piston 215 is sleeved in the barrel shell 209 and located above the conical pipe 210, and the upper end of the barrel shell 209 is provided with a driving member 216 for driving the piston 215 to move up and down in the barrel shell 209. The existing electric telescopic rod technology or the existing voice coil motor technology can be used, and details are not repeated here.

[0091] The outer surface of the valve shell 206 is provided with a side nozzle one below the valve plug 207, and the outer surface of the barrel shell 209 is provided with a side nozzle two between the conical pipe 210 and the annular plate 213, and the side nozzle one and the side nozzle two are connected.

[0092] The working process of the cleaning member 200 is specifically as follows:

[0093] Under the traction of the water pump 201, water is sprayed to sweet potatoes at the cleaning position through the water pipe 202, the pressure regulating assembly 203, the main pipe 204, the branch pipe 217, the flushing shaft 218 and the spray head 219, so as to flush the sweet potatoes. During the flushing process, the second motor 220 can drive the flushing shaft 218 to rotate with the spray head 219, and the rotation of the spray head 219 cooperates with the traction member 100 to realize the cleaning of the sweet potatoes. The cleaning process has been described in detail above, and details are not repeated here.

[0094] It should be emphasized that when the water passes through the pressure regulating assembly 203, a pulse cleaning effect is generated, which improves the cleaning effect of the sweet potatoes. Specifically, the water enters the area between the conical pipe 210 and the annular plate 213 through the valve shell 206, the side nozzle one and the side nozzle two, then enters the conical pipe 210 through the connecting hole and the upper one-way valve 212, and then flows into the main pipe 204 through the column pipe 211 and the lower one-way valve 214. That is to say, the barrel shell 209 is filled with water, and at the same time, the piston 215 is driven to move up and down by the driving member 216, so that the water pressure changes periodically from large to small, forming a pulse cleaning effect.

[0095] Preferably, a water tank 300 can be arranged below the drainage convex pipe 104, and a filter screen 301 is arranged in the water tank 300. The water inlet end of the water pump 201 is connected with the water tank 300, and the connection positions of the water pump 201 and the drainage convex pipe 104 are located on the two sides of the filter screen 301. The technical advantage is that the recycling of water resources is improved, and the environment is more friendly.

[0096] Further, after cleaning the sweet potatoes, there is a lot of mud in the water, and the filter screen 301 is easily blocked by simply using the filtering performance of the filter screen 301. Therefore, with reference to Figure 9The water tank 300 is provided with a plurality of partitions 302 on the same side of the filter screen 301, and the cooperation of the plurality of partitions 302 forms a continuous curved channel on the side of the filter screen 301 of the water tank 300. One side of the continuous curved channel is connected with the filter screen 301, and the other side is located below the drain convex pipe 104. Therefore, the slurry water output through the drain convex pipe 104 needs to pass through the continuous curved channel and then be filtered through the filter screen 301 to enter the other side of the water tank 300 and be sucked by the water pump 201. The continuous curved channel is equivalent to a sediment channel and can make large-particle silt precipitate, and cooperates with the filter screen 301 to realize the recycling of water.

[0097] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application.
