[0027] To better understand the purpose, functions, and specific design of the present utility model, the potato pretreatment grading and feeding system of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figures 1-8 shown, the potato pretreatment grading and feeding system of the present utility model includes a screening device 7. One end of the screening device 7 is provided with a feeding assembly 71, and the feeding assembly 71 is connected to a screen assembly 72. The screen assembly 72 includes three discharge ports, and each of the three discharge ports is connected to a conveying and transporting assembly 4. Each conveying and transporting assembly 4 is respectively connected to a feeding and transporting assembly 3, and a temporary storage box 1 is provided below each feeding and transporting assembly 3; potatoes can be transported to the screen assembly 72 through the feeding assembly 71 for screening and grading, and then large potatoes, medium potatoes, and small potatoes enter the corresponding conveying and transporting assemblies 4 through the three discharge ports respectively. The potatoes on the conveying and transporting assemblies 4 are respectively transported to the three temporary storage boxes 1 through the feeding and transporting assemblies 3 for storage and standby.

[0029] Specifically, as Figures 1-2 shown, the screening device 7 includes a screening trough 73. The feeding assembly 71 is arranged above one end of the screening trough 73. The feeding assembly 71 includes a feeding conveyor belt, and the feeding conveyor belt can transport potatoes to the screen assembly 72. The screen assembly 72 includes a first screen 721, a second screen 722, and a screening conveyor belt 723 that are parallelly distributed from top to bottom. The mesh diameter of the first screen 721 is larger than that of the second screen 722. A first conveying plate 74 is arranged at one end of the first screen 721 away from the feeding assembly 71, and one end of the first conveying plate 74 away from the first screen 721 is arranged above the conveying and transporting assembly 4 for transporting large potatoes. A second conveying plate 75 is arranged at one end of the second screen 722 away from the feeding assembly 71, and one end of the second conveying plate 75 away from the first screen 721 is arranged above the conveying and transporting assembly 4 for transporting medium potatoes. The end of the screening conveyor belt 723 is arranged above the conveying and transporting assembly 4 for transporting small potatoes.

[0030] After the potatoes enter the screen assembly 72, the large potatoes will not fall through the mesh of the first screen 721 onto the second screen 722. Therefore, the large potatoes slide down the first conveying plate 74 to the conveying and transporting assembly 4 for transporting large potatoes for transportation; the medium potatoes and small potatoes will fall through the mesh of the first screen 721 onto the second screen 722, but the medium potatoes will not fall through the mesh of the second screen 722 onto the screening conveyor belt 723. Therefore, the medium potatoes slide down the second conveying plate 75 to the conveying and transporting assembly 4 for transporting medium potatoes for transportation; the small potatoes will fall through the mesh of the second screen 722 onto the screening conveyor belt 723. Therefore, the small potatoes are transported by the screening conveyor belt 723 to the conveying and transporting assembly 4 for transporting small potatoes for transportation.

[0031] Preferably, in order to improve the screening efficiency, the first screen 721 and the second screen 722 of this embodiment are connected to the vibration assembly 76, and the vibration assembly 76 can drive the first screen 721 and the second screen 722 to vibrate reciprocally. Specifically, the screen assembly 72 includes a rocking link 77. The middle position of the rocking link 77 is hinged to the screening trough 73. The two ends of the rocking link 77 are respectively hinged to the first screen 721 and the second screen 722. The vibration assembly 76 is connected to the first screen 721 or the second screen 722, and can drive the first screen 721 and the second screen 722 to vibrate reciprocally together. The vibration assembly 76 of this embodiment can select components such as air cylinders or hydraulic cylinders that can provide reciprocating motion.

[0032] It should be noted that, in order to prevent the first screen 721 and the second screen 722 from driving the first conveying plate 74 and the second conveying plate 75 to shake together, the first screen 721 of this embodiment overlaps above the first conveying plate 74. The first conveying plate 74 is fixedly connected to the screening trough 73, and the first screen 721 can move relative to the first conveying plate 74; the second screen 722 overlaps above the second conveying plate 75. The second conveying plate 75 is fixedly connected to the screening trough 73, and the second screen 722 can move relative to the second conveying plate 75.

[0033] It should be noted that the bottom of the screening trough 73 of this embodiment is inclined. The height of the end of the screening trough 73 close to the conveying and transferring assembly 4 is higher than the height of the end of the screening trough 73 far from the conveying and transferring assembly 4. A soil discharge port 78 is provided at the end of the screening trough 73 far from the conveying and transferring assembly 4. The soil shaken off during the potato grading process can be discharged through the soil discharge port 78.

[0034] As Figures 3-8 shown, the temporary storage box 1 includes a feeding end and a discharging end. The conveying and transferring assembly 4 is arranged close to the feeding end. A discharging port 5 is provided at the discharging end. The discharging port 5 is arranged at the bottom of the temporary storage box 1. The potatoes in the temporary storage box 1 can be discharged through the discharging port 5; the feeding and transferring assembly 3 extends along the length direction of the temporary storage box 1 and is inclined relative to the horizontal direction. The potatoes on the feeding and transferring assembly 3 can fall into the temporary storage box 1 by gravity; when the stacking height of the potatoes at the feeding end reaches the height of the feeding and transferring assembly 3, the dropping point of the potatoes on the feeding and transferring assembly 3 will move towards the discharging end until the entire temporary storage box 1 is filled.

[0035] A buffer assembly 2 is provided at the feeding end. The buffer assembly 2 is arranged inside the temporary storage box 1. The buffer assembly 2 is connected to the feeding and transferring assembly 3. The potatoes on the conveying and transferring assembly 4 are conveyed to the buffer assembly 2 through the feeding and transferring assembly 3 and then enter the temporary storage box 1 for storage.

[0036] Specifically, as Figures 5-7As shown, the buffer assembly 2 includes a buffer frame 21. A plurality of buffer plates 22 are movably arranged on the buffer frame 21. After the potatoes are decelerated by the buffer plates 22, they fall into the temporary storage box 1. In this embodiment, the buffer plate 22 is fixedly connected to a rotating shaft 23. An articulated support ear 24 is arranged on the buffer frame 21, and the rotating shaft 23 is articulated with the articulated support ear 24. An elastic member is also sleeved on the rotating shaft 23, and the elastic member can reset the buffer plate 22 to the horizontal position after it falls.

[0037] In this embodiment, the elastic member is a torsion spring. A first limiting portion 25 is arranged on the articulated support ear 24. The two ends of the rotating shaft 23 are respectively fixedly connected to mounting plates 26. A second limiting portion is arranged on the mounting plates 26. The two ends of the torsion spring are respectively connected to the first limiting portion 25 and the second limiting portion. A buffer plate 22 is arranged on the mounting plate 26. In order to further enhance the buffering effect, the buffer plate 22 is made of a rubber plate.

[0038] As Figure 1 and Figure 3 shown, the feeding conveyor assembly 3 is arranged obliquely with respect to the horizontal direction. The height of the side close to the buffer assembly 2 is lower than the height of the side far from the buffer assembly 2. Thus, the potatoes on the feeding conveyor assembly 3 fall onto the buffer assembly 2 by gravity and then fall into the temporary storage box 1. The conveying conveyor assembly 4 is horizontally arranged. One end of the conveying conveyor assembly 4 is connected to the feeding conveyor assembly 3 and is arranged above the feeding conveyor assembly 3. The potatoes on the conveying conveyor assembly 4 can be conveyed onto the feeding conveyor assembly 3.

[0039] It should be noted that a baffle 31 is arranged at the end of the feeding conveyor assembly 3 close to the conveying conveyor assembly 4, and the baffle 31 can prevent the potatoes from falling outside the temporary storage box 1.

[0040] As shown in Figure 4, a plurality of fixed columns 11 are arranged on the top of the temporary storage box 1. The side of the feeding conveyor assembly 3 close to the buffer assembly 2 is articulated with the fixed columns 11. The side of the feeding conveyor assembly 3 far from the buffer assembly 2 is articulated with a telescopic assembly 32. The telescopic assembly 32 is articulated with the fixed columns 11. By adjusting the length of the telescopic assembly 32, the inclination angle of the feeding conveyor assembly 3 can be adjusted. It should be noted that when the dropping point of the potatoes on the feeding conveyor assembly 3 gradually moves towards the discharging end, at this time, the potatoes in the box act as a buffer, so the buffer assembly is no longer needed.

[0041] Preferably, a mud scraping plate 33 is arranged at the bottom of the feeding conveyor assembly 3 to scrape the soil on the conveyor belt of the feeding conveyor assembly 3.

[0042] As Figure 3 and Figure 8As shown in the figure, a support plate 6 is provided at the bottom of the temporary storage box 1. A discharge channel is formed between the support plate 6 and the bottom of the temporary storage box 1. The potatoes first enter the discharge channel and then are discharged from the discharge port 5. In this embodiment, the cross-section of the bottom of the temporary storage box 1 is an inverted trapezoid, and the support plate 6 is an inverted V shape. The lower bottom of the inverted trapezoid and the inverted V-shaped support plate 6 enclose to form the discharge channel. There is a gap between the support plate 6 and the waist of the inverted trapezoid, so that the potatoes can enter the discharge channel. By setting the discharge channel, the discharge port 5 can be prevented from being blocked by potatoes.

[0043] Preferably, a buffer layer 61 is provided on the upper surface of one end of the top of the support plate 6 close to the buffer assembly 2 to prevent the potatoes from being damaged. The buffer layer can be made of a rubber pad.

[0044] When the present utility model is in use, the discharge ports 5 at the bottoms of the three temporary storage boxes 1 are respectively connected to an output conveyor belt. When producing AA / A-level products, large potatoes plus a small proportion of medium potatoes can be selected to meet the quality requirements. If producing B-level products, 50% large potatoes, 30% medium potatoes, and 20% small potatoes can be used for production; if producing C-class products, 40% large potatoes, 30% medium potatoes, and 30% small potatoes can ensure production. The conveying speed of the output conveyor belt is controlled by frequency conversion for each proportion of potatoes out of the warehouse, so as to control the proportion of large, medium, and small potatoes, which is convenient for adjustment.

[0045] The structure of the present utility model is ingeniously designed and has a high degree of automation. By setting the screening device 7, the potatoes can be automatically classified and respectively conveyed to different conveying and conveying assemblies 4. And the temporary storage box 1 is fed by the cooperation of the conveying and conveying assembly 4 and the inclined feeding and conveying assembly 3. The potatoes can automatically fill the temporary storage box 1 along the feeding and conveying assembly 3. By setting the buffer assembly 2 and the buffer layer, the risk of the potatoes being damaged is greatly reduced. By setting the discharge channel, the discharge port 5 can be prevented from being blocked by potatoes, improving the reliability of the work.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
