Description

Technical Field

[0001] The invention relates to the technical field of potato transport equipment, and in particular to a potato transport equipment and a transport method for sorting potatoes after picking. Background Art

[0002] Potatoes, also known as potatoes, yam eggs, sweet potatoes, sweet potatoes, sweet potatoes, fragrant sweet potatoes, sweet potatoes, mountain sweet potatoes, Yang Yu, ground eggs, etc., belong to the Solanaceae family, an annual herb, and the tubers are edible. The tubers contain a lot of starch, which can provide abundant calories for the human body, and are rich in protein, amino acids, and a variety of vitamins and minerals. In particular, its vitamin content is the most complete among all grain crops.

[0003] After the potatoes are picked, they need to be transported to the storage box to facilitate the later sale of the potatoes.

[0004] The prior art still has the following disadvantages in the potato transportation process:

[0005] 1. After the potatoes are picked, a large amount of dirt adheres to their surface. In the prior art, the potatoes are directly placed in water for cleaning. However, the excessive dirt adhered to the surface causes the cleaning water to quickly become turbid, which in turn leads to poor cleaning effect of the subsequent potatoes.

[0006] 2. After the potatoes are harvested, they are of different sizes, so they need to be screened. They cannot be screened during transportation, which affects the later sale of potatoes.

[0007] 3. When cleaning potatoes, put them directly in water and stir them to clean them. This type of cleaning effect is poor, resulting in a lot of dirt still attached to the surface of the potatoes. In addition, after cleaning, the potatoes are attached with water, so when the potatoes are transported later, the water drips everywhere;

[0008] In view of the above problems, the present invention document proposes a potato transportation device and a potato transportation method for sorting after picking. Summary of the invention

Since there is a certain gap between the multiple conveying rollers, when transporting potatoes, the multiple conveying rollers screen potatoes of different sizes, and small potatoes fall onto the inclined panel through the gap. Under the giving way of the first spring, the potatoes can be prevented from being damaged during the falling process. When the potatoes fall onto the inclined panel, the soil on them is shaken off.

The potatoes fall between the two second cleaning cylinders, and one of the second cleaning cylinders is driven to rotate by a motor. The two second cleaning cylinders are connected by two gear transmissions, and the two second cleaning cylinders rotate towards each other. Since the rubber wheel is located below the two second cleaning cylinders, the potatoes are blocked, and the potatoes can stay between the two second cleaning cylinders.

A linkage mechanism is provided at the bottom of the rotating disk, which is used to drive the U-shaped plate to move intermittently to remove the obstruction to the potatoes. A discharge port is provided on one side of the annular ring for discharging the potatoes. The rotating disk drives the potatoes thereon to rotate. Since the rotating disk is concave and a rubber layer is provided on the top thereof to increase the friction between the rotating disk and the potatoes, when the rotating disk rotates, the potatoes move outward under the action of centrifugal force and are blocked by the annular ring. When the rotating disk rotates clockwise, the potatoes can be driven to gradually rotate to the discharge port. In the process of cooperation between the rotating disk and the annular ring, the moisture on the potatoes is thrown out and enters the liquid collecting tank through the second leakage hole, so as to avoid excessive moisture on the potatoes.

A rubber layer is provided on the top of the rotating disk to increase the friction between the potatoes and the rotating disk. The rotating disk drives the potatoes thereon to rotate. Since the rotating disk is concave, the potatoes are gathered in the middle and thrown outward under the action of centrifugal force, and the rubber layer provided on the top is used to increase the friction between the rotating disk and the potatoes, so that the rotating disk drives the potatoes to rotate to throw out the moisture.

As the speed of the rotating disk increases, when the centrifugal force of the potatoes is greater than the torsion of the torsion springs, the potatoes push the baffle to rotate and fall into the collection frame through the discharge port.

[0052] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0053] Example 1

[0054] Reference Figure 1-Figure 10 , transportation equipment, which is used in the field of potato transportation equipment, the equipment is mainly composed of a cleaning box 1, a frame 2, a conveying roller 4, a mobile collecting vehicle 17, a U-shaped frame 5, an inclined plate 6, a second cleaning cylinder 23, a hollow metal conveyor belt 28, a rotating disk 35, an annular ring 32, a screening structure, a mud peeling structure and a cleaning structure.

[0055] Reference Figure 2 , Figure 3 and Figure 7 The screening structure is installed on the top of the frame 2, and specifically includes a frame 3 and multiple conveying rollers 4. The multiple conveying rollers 4 are connected by sprockets and chain transmission to form a continuous conveying system. There is a certain gap between the conveying rollers 4. When potatoes pass through, potatoes with small particle sizes will fall into the mobile collection vehicle 17 below through the gap. The mobile collection vehicle 17 is provided with an inclined panel 18, which is connected to the fixed block 20 through multiple first springs 21 to achieve elastic support.

[0056] Specifically, when the potatoes fall on the inclined plate 18, the first spring 21 can reduce the impact force of the potatoes and vibrate to help shake off the soil on the surface of the potatoes. A stop bar 19 is provided on one side of the inclined plate 18 to prevent the soil from falling into the mobile collection vehicle 17, thereby achieving a preliminary separation of the soil and the potatoes.

[0057] Reference Figure 2 , Figure 3 and Figure 4 The mud stripping structure mainly includes a driven shaft 12, a cam 13, a main shaft 10, a first cleaning cylinder 11 and an inclined plate 6. The driven shaft 12 is rotatably connected to the top of the frame 2 through a base, and a plurality of cams 13 are fixedly sleeved on its outer wall. The main shaft 10 is rotatably connected to the U-shaped frame 5 and is located above the inclined plate 6. The outer wall of the main shaft 10 is fixedly sleeved with a first cleaning cylinder 11, and a brush is provided on the outer wall of the first cleaning cylinder 11. The main shaft 10 and the driven shaft 12 are connected through a synchronous wheel and a synchronous belt.

[0058] Specifically, during operation, the motor drives the main shaft 10 to rotate, and drives the driven shaft 12 to rotate synchronously through the synchronous wheel and the synchronous belt. The cam 13 rotates with the driven shaft 12, driving the inclined plate 6 to vibrate, thereby shaking off the soil on the surface of the potatoes. At the same time, the brush of the first cleaning cylinder 11 scrubs the potatoes passing by to further remove the soil. A plurality of first leakage holes 7 are provided in the inclined plate 6, and the shaken soil is discharged through the first leakage holes 7 to avoid accumulation on the inclined plate 6.

[0059] Reference Figure 2 Two second cleaning cylinders 23 are provided in the cleaning box 1, and brushes are provided on the outer wall thereof for comprehensive cleaning of the potatoes. A hollow metal conveyor belt 28 is also provided in the cleaning box 1 to convey the cleaned potatoes to the outside.

[0060] Reference Figure 2 , Figure 6 and Figure 8 The cleaning structure includes a U-shaped plate 29 sliding on the inner wall of the bottom of the cleaning box 1. A set of rubber wheels 30 are rotatably connected inside the U-shaped plate 29. The position of these rubber wheels 30 is just below the two second cleaning cylinders 23. Its main function is to provide a certain obstruction when the potatoes pass through, so that the potatoes can stay between the two second cleaning cylinders 23. The outer walls of the two second cleaning cylinders 23 are fixedly sleeved with mutually meshing gears 24, so that when one of the second cleaning cylinders 23 is driven to rotate by the motor, the other will also rotate in the opposite direction through the transmission of the gear 24, thereby achieving comprehensive cleaning of the potatoes. In order to achieve continuous transportation and cleaning of potatoes, we set two first conveyor rollers 25, a third conveyor roller 27 and a second conveyor roller 26 set away from the frame 2 in the cleaning box 1. These conveyor rollers are connected by a hollow metal conveyor belt 28 to form a closed-loop conveying system.

[0061] Specifically, when the potatoes are conveyed between the two second cleaning cylinders 23, due to the contact between the hollow metal conveyor belt 28 and the rubber wheel 30, the movement of the conveyor belt will drive the rubber wheel 30 to rotate, and then the potatoes resting thereon will also rotate, thereby obtaining a more thorough cleaning.

[0062] Reference Figure 2 and Figure 8 In order to guide the potatoes into the cleaning area, two guide plates 22 are fixed above the two second cleaning cylinders 23. Their function is to accurately guide the potatoes between the two cleaning cylinders.

[0063] Reference Figure 2 A rotating disk 35 and an annular ring 32 are provided on the side of the washing box 1 away from the frame 2. The potatoes are transported to the rotating disk 35 by the hollow metal conveyor belt 28. As the rotating disk 35 rotates, the potatoes are swung in the annular ring 32, and the water on the surface of the potatoes is dried by centrifugal force.

[0064] Reference Figure 2 and Fig. 9 The centrifugal structure is mainly composed of two horizontal plates 31, an annular ring 32, a mounting plate 36, a driving shaft 37, a rotating disk 35, a driving motor 38, a liquid collecting tank 33 and a plurality of second leakage holes 34. The two horizontal plates 31 are fixed to one side of the cleaning box 1 and support the annular ring 32. The driving shaft 37 is rotatably connected to the mounting plate 36, and the top of the driving shaft 37 is fixedly connected to the rotating disk 35, and the bottom thereof is driven by the driving motor 38 on the frame 3. The top of the rotating disk 35 is designed to be concave and covered with a rubber layer to increase the friction between the rotating disk 35 and the potatoes.

[0065] Specifically, when the driving motor 38 is working, the rotating disk 35 will rotate accordingly, and the potatoes will move outward under the action of centrifugal force and be blocked by the annular ring 32. The second leakage hole 34 on the annular ring 32 is connected to the liquid collecting tank 33, which is used to collect the water thrown out of the potatoes during the rotation process. When the potatoes are thrown to the discharge port 39, they will naturally fall to the next processing link.

[0066] Reference Figure 8-Figure 10 In order to realize the intermittent movement of the U-shaped plate 29 to remove the obstruction to the potatoes, we designed a linkage mechanism. The mechanism includes a track groove arranged at the bottom of the rotating disk 35, and the track groove is composed of a V-shaped groove 41 and an annular groove 40, and the two are connected. A pin 42 is slidably fitted in the track groove, and a connecting plate 43 is fixed to the bottom of the pin 42, and a Z-shaped rod 44 is fixed to one side of the connecting plate 43. One end of the Z-shaped rod 44 extends into the washing box 1 in a sealed sliding manner and is fixedly connected to the U-shaped plate 29. In addition, the outer wall of the Z-shaped rod 44 is also sleeved with a second spring 45, and the two ends of the second spring 45 are respectively fixedly connected to the washing box 1 and the connecting plate 43.

[0067] Specifically, when the driving motor 38 drives the rotating disk 35 to rotate, the pin 42 will slide in the track groove. When the pin 42 slides from the V-shaped groove 41 into the annular groove 40, it will drive the connecting plate 43 and the Z-shaped rod 44 to move to the left, thereby pushing the U-shaped plate 29 to slide, so that the rubber wheel 30 can release the obstruction to the potatoes. When the pin 42 slides out of the annular groove 40 and re-enters the V-shaped groove 41, due to the elastic force of the second spring 45, the connecting plate 43 and the Z-shaped rod 44 will move to the right and reset, and the U-shaped plate 29 will also return to its original position. In this way, the intermittent movement function of the U-shaped plate 29 is realized.

[0068] Through the above implementation methods, we can effectively realize the processing processes such as continuous transportation, comprehensive cleaning and centrifugal dehydration of potatoes, and improve the subsequent processing quality and efficiency of potatoes.

[0069] Reference Figure 1 and Figure 2In order to more effectively remove the dirt on the surface of the potatoes after picking, this embodiment describes in detail the vibration structure of the washing box 1 and the inclined plate 6. On the side of the washing box 1 close to the mobile collection vehicle 17, a placing plate 14 is fixedly installed below the inclined plate 6. The main function of the placing plate 14 is to carry the dirt that is shaken off by the inclined plate 6 when it vibrates.

[0070] Reference Figure 2 and Figure 7 A mud guide groove 15 is provided on one side of the cleaning box 1, and a mud guide plate 16 is fixedly installed inside the mud guide groove 15. The design of the mud guide plate 16 is cleverly matched with the inclined plate 6 to ensure that the mud falling from the inclined plate 6 can be smoothly guided to the placement plate 14, thereby realizing effective collection of the mud.

[0071] Reference Figure 4 A plurality of convex strips 8 are fixed on the top of the inclined plate 6, and these convex strips 8 play a blocking role for the potatoes during the vibration process, preventing the potatoes from rolling directly into the cleaning box 1, so that the potatoes can withstand the vibration on the inclined plate 6 for a longer time, thereby improving the soil removal effect.

[0072] Reference Figure 4 In addition, a limit plate 9 is fixedly installed in the U-shaped frame 5 and is located below the inclined plate 6 to limit the inclined plate 6 and ensure that it remains stable during the vibration process. The cam 13 is connected to the inclined plate 6 through a mechanical transmission device. When the cam 13 rotates, the undulation of its profile drives the inclined plate 6 to vibrate, thereby shaking off the soil on the surface of the potatoes.

[0073] Reference Fig. 9 In order to further improve the cleanliness of potatoes, the top of the rotating disk 35 in this embodiment is designed to be concave, which helps the potatoes gather in the middle during the rotation process and be thrown out to the outside under the action of centrifugal force. At the same time, a rubber layer is laid on the top of the rotating disk 35 to increase the friction between the potatoes and the rotating disk 35, ensuring that the rotating disk 35 can effectively drive the potatoes to rotate and throw out the moisture.

[0074] Specifically, when the rotating disk 35 starts to rotate, the potatoes thereon start to move outwards under the action of centrifugal force and throw away the excess water. The presence of the rubber layer not only increases the friction force, but also reduces the damage of the potatoes during the water throwing process.

[0075] Overall workflow: potatoes are first conveyed and preliminarily screened by conveyor rollers 4, and small-size potatoes fall into mobile collection vehicle 17. Large-size potatoes continue to be conveyed forward to the desludging structure, where they are vibrated by inclined plates 6 and scrubbed by first cleaning cylinders 11 to remove surface dirt. Subsequently, potatoes enter the cleaning box 1, where they are fully cleaned by second cleaning cylinders 23 and conveyed by hollow metal conveyor belts 28, and finally, the surface moisture is removed by the drying action of rotating disks 35 and annular rings 32, completing the entire sorting, cleaning and drying process.

[0076] Example 2

[0077] refer to Fig.11 , improved on the basis of Example 1: In order to achieve graded discharge of potatoes, two base plates 46 are fixedly installed on the top of the annular ring 32 in this embodiment, and a rotating shaft 47 is rotatably connected between the two base plates 46. A baffle 48 for closing the discharge port 39 is fixedly sleeved on the outer wall of the rotating shaft 47, and two torsion springs 49 are also sleeved on the outer wall of the rotating shaft 47.

[0078] The ends of the two torsion springs 49 that are close to each other are fixedly connected to the two sides of the baffle 48, while the ends that are far away from each other are fixedly connected to the two base plates 46. This design enables the baffle 48 to maintain the closed state of the discharge port 39 under the action of the torsion springs 49.

[0079] Specifically, when the potatoes rotate with the rotating disk 35 in the annular ring 32, if the centrifugal force on them is less than the torsion of the torsion spring 49, the potatoes will be blocked by the baffle 48 and cannot fall into the external collection frame through the discharge port 39. In this way, the potatoes can continue to rotate in the annular ring 32 to remove more water.

[0080] However, as the rotation speed of the rotating disk 35 increases, the centrifugal force on the potatoes will gradually increase. When the centrifugal force is greater than the torque of the torsion spring 49, the potatoes will push the baffle 48 to rotate around the rotating shaft 47, thereby opening the discharge port 39 and falling into the collection frame below. This design realizes the automatic grading and discharge function of potatoes, and improves the automation level and cleaning efficiency of the entire potato transportation equipment.

[0081] A method for transporting potatoes after picking and sorting, comprising the following steps:

[0082] S1, putting the picked potatoes on the conveyor roller 4, and the multiple conveyor rollers 4 are connected by sprockets and chains. Since there are certain gaps between the multiple conveyor rollers 4, when transporting potatoes, the multiple conveyor rollers 4 screen potatoes of different sizes, and small potatoes fall on the inclined plate 18 through the gaps. Under the giving effect of the first spring 21, the potatoes can be prevented from being damaged during the falling process, and when the potatoes fall on the inclined plate 18, the soil on them is shaken off. When the inclined plate 18 discharges the potatoes to one side, the stop bar 19 blocks the soil, preliminarily clears the soil on the potatoes, and facilitates the later cleaning;

[0083] S2, potatoes with large particle size fall into the washing box 1 through the inclined plate 6, and the main shaft 10 and the first cleaning cylinder 11 are driven by the motor to rotate. The main shaft 10 and the driven shaft 12 are connected by synchronous wheels and synchronous belts. The cam 13 drives the inclined plate 6 to vibrate, which is used to shake off the soil attached to the surface of the potatoes, and the shaken soil falls on the placement plate 14 through the first leakage hole 7, and the convex strips 8 block the potatoes to prevent the potatoes from rolling directly into the washing box 1. When the inclined plate 6 vibrates and discharges the potatoes to one side, the first cleaning cylinder 11 can further brush off the soil on the surface of the potatoes. The cooperation between the inclined plate 6 and the mud guide plate 16 can discharge the soil shaken off from the inclined plate 6 to the placement plate 14 again, so as to prevent the soil from entering the washing box 1 and affecting the cleanliness of the water in the washing box 1;

[0084] S3, the cooperation of the two guide plates 22 guides the potatoes falling into the cleaning box 1 to between the two second cleaning cylinders 23, and one of the second cleaning cylinders 23 is driven to rotate by the motor, and the two second cleaning cylinders 23 are connected by two gears 24, and the two second cleaning cylinders 23 rotate towards each other. Since the rubber wheel 30 is located below the two second cleaning cylinders 23, it hinders the potatoes, and the potatoes can stay between the two second cleaning cylinders 23, and the hollow metal conveyor belt 28 touches the rubber wheel 30, the hollow metal conveyor belt 28 drives the rubber wheel 30 to rotate, and the rubber wheel 30 drives the potatoes thereon to rotate, so the two second cleaning cylinders 23 can clean the potatoes more comprehensively;

[0085] S4. In addition, when the driving motor 38 drives the driving shaft 37 and the rotating disk 35 to rotate, the pin 42 cooperates with the annular groove 40 and the V-shaped groove 41 to intermittently drive the connecting plate 43 and the Z-shaped rod 44 to move left and right, and the Z-shaped rod 44 drives the U-shaped plate 29 to move, and the rubber wheel 30 releases the obstruction to the potatoes, and the potatoes fall onto the hollow metal conveyor belt 28, and the hollow metal conveyor belt 28 conveys the cleaned potatoes to the right and falls onto the rotating disk 35;

[0086] S5, the rotating disk 35 drives the potatoes thereon to rotate. Since the rotating disk 35 is concave, it is used to gather the potatoes in the middle and throw them outward under the action of centrifugal force. A rubber layer is arranged on the top of the rotating disk 35 to increase the friction between the rotating disk 35 and the potatoes. When the rotating disk 35 rotates, the potatoes move outward under the action of centrifugal force and are blocked by the annular ring 32. When the rotating disk 35 rotates clockwise, it can drive the potatoes to gradually rotate to the discharge port 39. In the process of cooperation between the rotating disk 35 and the annular ring 32, the moisture on the potatoes is thrown out and enters the liquid collecting tank 33 through the second leakage hole 34, so as to avoid excessive moisture on the potatoes.

[0087] S6. When the centrifugal force on the potatoes is less than the torque of the torsion spring 49, the potatoes are blocked by the baffle 48 and cannot fall into the external collection frame through the discharge port 39. Then the potatoes can continue to remove moisture in the annular ring 32. As the speed of the rotating disk 35 increases, the centrifugal force of the potatoes is greater than the torque of the torsion spring 49, and the potatoes push the baffle 48 to rotate and fall into the collection frame through the discharge port 39.

[0088] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 38 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0089] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
