Description

Technical Field

[0001] The utility model relates to the technical field of potato size sorting, in particular to a size sorting device for potato planting and harvesting. Background Technique

[0002] With the continuous expansion of the market demand for potatoes, the planting area of potatoes is also increasing, and the market's quality requirements for potatoes are getting higher and higher. In order to ensure that potatoes of the same grade and quality have consistent specifications, it is also an essential and important link to grade the size of potatoes. Therefore, a sorting machine is needed to sort potatoes of different sizes.

[0003] By comparing with the potato size sorting machine with the patent publication number CN218963192U, in this solution, when this device sorts a large number of potatoes, the simultaneous feeding of a large number of potatoes with different volumes may cause accumulation above the discharge roller at the rear end. When the discharge roller at the rear end sorts the potatoes with the smallest volume, potatoes with a larger volume may accumulate at the bottom, and some potatoes with a smaller volume may accumulate at the top. Therefore, when the potatoes are transported and sorted step by step from the back to the front, the potatoes with a larger volume will drive the potatoes with a smaller volume above them to move forward, which may cause the potatoes with a smaller volume not to be correctly sorted, thus reducing the sorting quality and increasing the workload of re-sorting in the later stage.

[0027] As Figures 1 - 5 shown, a size sorting device for potato planting and harvesting includes a bottom plate 100 and a sorting mechanism for sorting the sizes of potatoes. The sorting mechanism is located on the front side of the bottom plate 100, and further includes a feeding mechanism for feeding potatoes, and the feeding mechanism is located on the rear side of the bottom plate 100.

[0028] In this embodiment: The sorting mechanism includes two support plates 301 arranged on the front side of the bottom plate 100 and symmetrically arranged. A plurality of rollers 302 are rotatably installed between the two support plates 301, and the spacing between the plurality of rollers 302 increases sequentially from back to front.

A second material storage box 304 is arranged below the roller 302. A first material storage box 303 is arranged at the rear side of the second material storage box 304, and a third material storage box 305 is arranged at the front side. The third material storage box 305, the second material storage box 304, and the first material storage box 303 are all slidably connected to the bottom plate 100. When the potatoes move forward, the spacing between the plurality of rollers 302 increases sequentially from back to front, so as to screen potatoes of different sizes. The third material storage box 305, the second material storage box 304, and the first material storage box 303 collect potatoes of different sizes, and the sorting of potatoes of different sizes is completed.

[0029] In this embodiment: The blanking mechanism includes a blanking component for controlling the blanking amount of potatoes and a cleaning component for preliminarily cleaning the soil on the surface of the potatoes.

[0030] The blanking component includes a feed bin 201 arranged at the rear side of the bottom plate 100. Two blanking plates 202 are fixed at the upper end inside the feed bin 201 and symmetrically arranged. The blanking plates 202 are inclined downward. A plurality of rollers 214 are rotatably installed on the surface of the blanking plates 202. Two buffer plates 206 are arranged below the blanking plates 202 and symmetrically arranged. The buffer plates 206 are rotatably connected to the feed bin 201. A torsion spring is connected between the buffer plates 206 and the inner wall of the feed bin 201. The buffer plates 206 are inclined downward. A blanking channel 209 is fixedly arranged at one end of the feed bin 201 close to the roller 302 below. A blanking bin 213 is arranged between the blanking channel 209 and the roller 302. The blanking bin 213 is fixedly connected to the support plate 301. A material pushing structure is arranged at the front side of the blanking bin 213, and the material pushing structure is used for pushing the potatoes piled up above the roller 302 backward.

[0031] The material pushing structure includes a material pushing roller 210 arranged at the front side of the blanking bin 213. The material pushing roller 210 is rotatably connected to the support plate 301. A driving motor 212 is installed at the rotating end of the material pushing roller 210. A plurality of push plates 211 are evenly distributed around the surface of the material pushing roller 210. The push plates 211 are slidably connected to the material pushing roller 210. A compression spring is connected between the push plates 211 and the material pushing roller 210.

[0032] The cleaning component includes two brush rollers 203 arranged between the blanking plate 202 and the buffer plate 206, and they are symmetrically arranged. The rotating end of the brush roller 203 is provided with a rotating motor 205. A rotating gear 204 is fixedly installed on the brush roller 203, and the two rotating gears 204 are meshed with each other. A filter plate 207 is arranged directly below the buffer plate 206. The filter plate 207 is inclined towards the blanking channel 209. A waste box 208 is arranged below the filter plate 207. The waste box 208 is slidably connected to the feed bin 201. The two symmetrically arranged blanking plates 202 and the buffer plate 206 in the blanking component are used to batch-feed a large number of potatoes, which has a certain function of controlling the feeding amount of potatoes. At the same time, the buffer plate 206 has a certain buffering effect on the falling potatoes, reducing the impact force formed when the potatoes fall and causing damage to the potatoes. Then, the dialing structure is used to dial the potatoes piled up at the rearmost side of the roller 302 towards the rear side, reducing the phenomenon of potatoes of different volumes piling up, thereby reducing the phenomenon that smaller-volume potatoes cannot be correctly sorted. Therefore, the sorting quality is improved and the workload of re-sorting in the later stage is reduced.

[0033] Working principle: First, start the drive motor 306. Using the drive of the belt, drive the rearmost roller 302 to rotate. Then, use the drive sprocket 307 on the roller 302 to mesh with the drive chain 308, thereby driving all the rollers 302 to rotate simultaneously. Then, pour a large number of potatoes of different sizes and volumes into the feed bin 201. Use the two symmetrically arranged blanking plates 202 at the upper end to batch-feed the potatoes, which has a function of controlling the feeding amount of potatoes. The multiple rollers 214 arranged on the surface of the blanking plate 202 facilitate the downward sliding of the potatoes.

[0034] Then start the rotating motor 205. Using the meshing of the two rotating gears 204 on the two brush rollers 203, drive the two brush rollers 203 to rotate in opposite directions, and then slightly clean the surface of the potatoes falling downward, initially cleaning the soil on the surface of the potatoes. The cleaned potatoes fall between the two buffer plates 206 below. The falling potatoes impact the two buffer plates 206 downward, causing the two buffer plates 206 to open downward, allowing the potatoes to fall downward. At the same time of the impact, using the elastic connection between the two buffer plates 206 and the feed bin 201, the two buffer plates 206 form a certain buffer for the falling potatoes, reducing the impact force formed when the potatoes fall and causing damage to the potatoes. Then, the cleaned and fallen soil is filtered by the filter plate 207 and collected in the waste box 208 below.

[0035] Then, the cleaned potatoes move forward, flow out from the feeding channel 209, and flow over the rollers 302 at the front and rear ends. The potatoes are driven to move forward by the rotation of the multiple rollers 302. The convex strips arranged on the surface of the rollers 302 increase the friction between the potatoes and the potatoes, which is conducive to the forward movement of the potatoes. At the same time, the shifting motor 212 drives the shifting roller 210 to rotate, and drives the multiple shifting plates 211 to rotate, so as to shift the potatoes that may be piled up backward, thereby reducing the accumulation of potatoes of different sizes, thereby reducing the phenomenon that potatoes of smaller sizes cannot be correctly sorted, thereby improving the sorting quality and reducing the workload of re-sorting in the later stage. When the potatoes move forward, the spacing between the multiple rollers 302 increases from the back to the front, and potatoes of different sizes are screened to different sizes. The third material box 305, the second material box 304 and the first material box 303 collect potatoes of different sizes to complete the sorting of potatoes of different sizes.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
