Description

Technical Field

[0001] This utility model relates to the field of seed impurity removal technology, and in particular to a peanut seed impurity removal device. Background Technology

[0002] Peanut seed screening is a common and relatively simple way to improve peanut seed quality, and it is an important step in ensuring seed quality in peanut production. The screening process has specific requirements for the plumpness, size, and shape of the selected peanut seeds, while also removing impurities such as stones and soil.

[0003] By comparing a peanut seed impurity removal device with screening function in patent publication number CN222000669U, it is found that in this solution, the drive motor drives the baffle and multi-stage filter cylinder to rotate, which can realize the tumbling of peanut seeds, thereby improving the efficiency and effect of peanut seed impurity removal. Furthermore, by setting the multi-stage filter cylinder to an inclined state, the peanut seeds can move to the right end of the multi-stage filter cylinder during the tumbling process, achieving efficient impurity removal of peanut seeds. However, after peeling the peanuts, some peanut skin residue may remain among a large number of peanut seeds. When removing impurities from peanut seeds, since the peanut skin and peanut seeds are similar in size, the peanut skin residue may not be screened well. This peanut skin residue will continue to remain among a large number of peanut seeds, which increases the difficulty of screening and reduces the quality of impurity removal. Utility Model Content

A waste bin 226 is provided below the screening table 203. A front waste bin 227 is provided in front of the waste bin 226. A rear waste bin 228 is provided behind the waste bin 226. Vibration structures for driving the screening table 203 to float up and down are provided on both the front and rear sides of the screening table 203. A flotation structure for flotation of peanut skins is provided behind the screening table 203.

[0028] The flotation structure includes a flotation chamber 210 located behind the large screen plate 205. The flotation chamber 210 is fixedly connected to the screening table 203. The flotation chamber 210 is an inverted triangle. Multiple water passage holes 214 are provided at the bottom of the flotation chamber 210. Two sliding frames 211 are fixed at the bottom of the flotation chamber 210 and are symmetrically arranged in the left-right direction. A sealing plate 212 is slidably installed between the two sliding frames 211. The sealing plate 212 is located below the water passage holes 214. A moving cylinder 213 is provided between the sealing plate 212 and the sliding frame 211. A retrieval structure for retrieval of peanut shells floated on the water surface is provided above the flotation chamber 210.

[0029] The retrieval structure includes two fixed frames 219 symmetrically arranged in the left-right direction on the rear side of the screening table 203. A lifting frame 221 is slidably installed between the two fixed frames 219. A hydraulic cylinder 220 is provided between the lifting frame 221 and the fixed frames 219. Two slide rails 222 symmetrically arranged in the left-right direction are provided on the upper end of the lifting frame 221. A lead screw 223 is rotatably installed inside the slide rail 222. A moving motor 224 is installed on the rotating end of the lead screw 223. The output end of the moving motor 224 is fixed to the rotating end of the lead screw 223 through a coupling. A debris barrier 225 is slidably installed between the two slide rails 222. The debris barrier 225 is threadedly connected to the lead screw 223. Multiple drainage grooves are opened at the bottom end of the debris barrier 225. A wastewater tank 229 is provided below the flotation chamber 210.

[0030] The vibrating structure includes connecting plates located on opposite sides of the front bottom frame 201 and the rear bottom frame 202. A rotating shaft 215 is rotatably mounted between the two connecting plates. Impact cams 216 are fixed to both ends of the rotating shaft 215. Two symmetrically arranged protrusions 217 are installed at both ends of the screening table 203. The protrusions 217 and the impact cams 216 are arc-shaped and slide in contact with each other. A rotary motor 218 is installed at the rotating end of the rotating shaft 215. The output end of the rotary motor 218 is fixed to the rotating end of the rotating shaft 215 via a coupling. Both the impact cams 216 and the protrusions 217 are made of rubber. The impurity removal mechanism first filters out particulate impurities and soil present between the peanut seeds. The vibrating structure accelerates the screening time. Then, the seeds are soaked in water. Due to the difference in specific gravity between peanut seeds and peanut skins, the peanut skins float on the water surface. A flotation structure is then used to remove the floating peanut skins, preventing peanut skin residue from mixing with the seeds, increasing the scope of impurity removal, and improving the quality of impurity removal.

[0031] Working principle: First, the peanut seeds to be cleaned are poured onto the upper side of the screening table 203. Then, the rotary motor 218 is started to drive the rotating shaft 215 to rotate, which in turn drives the striking cam 216 to rotate. The striking cam 216 and the protrusion 217 on the side wall of the front bottom frame 201 squeeze and collide with each other, which causes the protrusion 217 to move the screening table 203 up and down, causing the screening table 203 to vibrate slightly. Taking advantage of the inclined characteristic of the screening table 203, the peanut seeds will pass through the small sieve plate 204 first. The small sieve plate 204 filters out the fine soil impurities between the peanut seeds. Then, these impurities fall into the front waste bin 227 below.

[0032] Then, the front cylinder 207 drives the front partition 206 to move upward, breaking free from the obstruction of the seeds. The seeds continue to roll downward and pass through the large sieve plate 205 to filter out smaller and damaged seed particles and remove impurities. Larger particles are also filtered out, and these impurities fall into the rear waste bin 228 below.

[0033] Then, the rear cylinder 209 continues to drive the rear partition 208 upward, and the rear partition 208 is no longer obstructing the seeds. The seeds continue to roll downward into the flotation chamber 210 on the rear side. Then, water is added into the flotation chamber 210. Due to the different specific gravities of peanut seeds and peanut skins, the peanut seeds will sink to the bottom of the flotation chamber 210, while the peanut skins will float on the surface. At this time, the hydraulic cylinder 220 is activated to drive the lifting frame 221 downward, which in turn moves the debris barrier 225 downward, placing the debris barrier 225 at the front of the peanut skins. Then, the moving motor 224 is activated to drive the lead screw 223 to rotate, which moves the debris barrier 225 backward, thereby blocking all the peanut skins on the water surface inside the debris barrier 225. Then, the hydraulic cylinder 220 is driven to drive the lifting frame 221 upward, which in turn moves the debris barrier 225 upward, removing the peanut skins inside the debris barrier 225 from the water surface for cleaning, thereby increasing the range of impurity removal and improving the quality of impurity removal.

[0034] Then, the moving cylinder 213 drives the sealing plate 212 to move forward. The sealing plate 212 no longer blocks the water passage 214, and the water flow inside the flotation chamber 210 is collected and recycled inside the wastewater tank 229. At this time, the peanut seeds have completed the impurity removal process and are all gathered inside the flotation chamber 210. Then, the seeds are taken out to complete the seed impurity removal operation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
