[0022] The present application has the following technical effects compared with the prior art:

[0023] 1) The seed potato grading and sorting mechanism can store seed potatoes from the source, continuously supply seed potatoes to the whole cutting line, reduce resource waste, and improve the efficiency of the whole line; secondly, the grading and sorting mechanism can reasonably grade the potato according to the size of the potato structure, so as to realize targeted cutting scheme for seed potatoes of different sizes; thirdly, the independent adjustment mechanism of the spring roller can steplessly adjust according to the actual situation of the seed potato, improve the sorting threshold, and has better practicality; finally, the rotation of the spring roller has better flattening effect on the incoming material, reduces the accumulation of the incoming material, and better realizes the sorting function.

[0024] Further, the spring roller can be replaced by a rubber finger roller. The rubber finger roller is a cylindrical body with a square hole in the middle. Eight rubber fingers are evenly distributed on the outer surface of the middle part of the cylindrical body, and the direction is coincident with the tangent of the surface of the cylindrical body. It belongs to the structure of imitated fingers. The movement direction of the rubber fingers is the tangent direction of the rotation axis, which is consistent with the movement direction of the potatoes. Multiple rubber finger rollers are arranged in the same axial direction, and there is a fixed gap between the rubber fingers. The advantage of the rubber finger structure is that the imitated finger structure has a good pushing effect on the incoming potatoes, making the potatoes pass through the sorting channel more smoothly and reducing the accumulation of incoming materials. In addition, there is a fixed distance between the fingers, which is equivalent to setting a fixed length and width space between the rubber finger rollers on the same axis. Compared with the spring roller group, the advantage is that the sorting conditions are more complete, which can improve the sorting accuracy and indirectly improve the rationality and uniformity of potato cutting.

[0025] 2) In the small potato cutting device, the conveying mode of the tapered roller conveyor belt is set to arrange and convey incoming small potatoes of various postures.

At the same time, a rack is installed on one side of the device, and a gear is installed on one side of the tapered roller, which is engaged with the rack to drive the self-rotation of each group of tapered rollers while the conveyor belt is advancing. The setting of this transmission structure can rotate and arrange the small potatoes, so that the small potatoes falling on one side are rotated and moved to the middle position of the tapered roller channel, so that the small potatoes are cut from the middle position to ensure uniform cutting.

[0026] 3) In the medium potato cutting device, the guide plate is set to arrange and prepare the incoming medium potatoes before cutting, so that the seed potatoes entering the camera recognition are arranged in a certain order to improve the accuracy of camera recognition and prevent the distance between the potatoes during cutting from being too close to interfere with each other. Secondly, the speed of the guide platform conveyor belt is less than the speed of the mechanical arm workbench conveyor belt. This setting can use the speed difference to pull apart the distance between the front and rear potatoes when the potatoes are converted on the platform, and cooperate with the guide mechanism of the former to maximize the distance between the front, rear, left and right to reduce the mutual influence between the potatoes.

[0027] 4) The setting of the mechanical arm end cutter can classify the incoming medium potatoes by using different shaped cutters. The smaller part of the incoming medium potatoes is cut into three pieces using a Y-shaped cutter, and the larger part is cut into four pieces using a cross-shaped cutter or replaced with a six-equal-division cutter to cut into six pieces, so that the finally cut potato seed pieces can maximize the uniformity of weight and shape to ensure the uniformity of the whole cutting.

[0028] 5) The setting of the large potato manual cutting platform module can adjust in time according to the actual production status. The extremely large shape of the seed potatoes is manually cut in a targeted manner to reduce the waste of potato seeds and improve the cutting accuracy. BRIEF DESCRIPTION OF DRAWINGS

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0049] The purpose of the present application is to provide a potato cutting machine to solve the problems existing in the prior art.

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0051] The potato cutting machine in the present embodiment, such as Figures 1-8As shown, including a seed potato grading and sorting device 1, small potato cutting device 2, medium potato mechanical arm cutting device 3, large potato manual hand cutting platform and seed dressing device 4; the seed potato grading and sorting device 1 includes a hopper 101 and a sorting roller platform 102, the hopper 101 is used to store and transport the cutting potato seed potatoes to the sorting roller platform 102, the sorting roller platform 102 includes a plurality of spring roller groups or a plurality of rubber finger roller groups, each spring roller group is composed of a plurality of spring rollers 103 which are spaced from each other to form a material leakage gap, each spring roller group selects the material leakage gap according to the size of the seed potatoes to be sorted, each rubber finger roller group is composed of a plurality of rubber finger rollers 110 which are spaced from each other to form a material leakage gap, each rubber finger roller group selects the material leakage gap according to the size of the seed potatoes to be sorted, and each spring roller group or rubber finger roller group is provided with a corresponding conveying belt at the bottom, and each conveying belt transports the sorted seed potatoes to the small potato cutting device 2, the medium potato mechanical arm cutting device 3, the large potato manual hand cutting platform and the seed dressing device 4 respectively; wherein the ends of the small potato cutting device 2 and the medium potato mechanical arm cutting device 3 are connected to the seed dressing device 4.

[0052] The sorting roller platform 102 realizes the sorting of different size seed potatoes, the same size seed potatoes are transported to the corresponding processing device through the corresponding conveying belt for processing, the too small seed potatoes are directly transported to the seed dressing device 4, the small potatoes are transported to the small potato cutting device 2 for cutting, the medium potatoes are transported to the medium potato mechanical arm cutting device 3 for cutting, and a few large individual potatoes are not selected, and are transported to the large potato manual hand cutting platform through the conveying belt, and are manually cut according to the distribution of the bud eyes on the large individual potatoes. While ensuring that the large individual potatoes are cut uniformly, the waste of potato seed potatoes is reduced, and the manual cutting operation process can also manually cut the potatoes which are not cut or are not cut uniformly by the small potato cutting device 2 and the medium potato mechanical arm cutting device 3, thereby maximizing the cutting effect of potato seed potatoes. When all the potato cutting procedures are completed, the seed potato pieces are uniformly collected to the potato seed dressing machine through the conveying belt, and the potato seed dressing operation is performed.

[0053] In the embodiment, the seed potato grading and sorting device 1 further includes a rack 104 supported at the bottom of the hopper 101 and the sorting roller platform 102; the hopper 101 is internally provided with a lifting conveying belt 105, and the hopper 101 transports the seed potatoes to the sorting roller platform 102 through the lifting conveying belt 105.

[0054] The spring roller group or the rubber finger roller group is sequentially provided with a non-cutting potato sorting roller group, a small potato sorting roller group and a medium potato sorting roller group from the front end to the tail end. The bottom of the non-cutting potato sorting roller group is provided with a non-cutting potato conveying belt 106. The tail end of the non-cutting potato conveying belt 106 is connected with a seed dressing conveying belt 5 for feeding the seed dressing device 4 through a transfer conveying belt 106. The bottom of the small potato sorting roller group is provided with a small potato conveying belt 107. The tail end of the small potato conveying belt 107 is connected with a small potato cutting device 2. The bottom of the medium potato sorting roller group is provided with a medium potato conveying belt 108. The tail end of the medium potato conveying belt 108 is connected with a medium potato mechanical arm cutting device 3. The tail end of the spring roller group or the rubber finger roller group is connected with a large potato conveying belt 109. The heights of the spring rollers 103 or the rubber finger rollers 110 of the sorting roller platform 102 gradually decrease from the front end to the tail end, so that the top of the sorting roller platform 102 is in a slope shape. The slope-shaped sorting roller platform 102 is more conducive to conveying the seed potatoes to the tail end.

[0055] The spring roller group is the main sorting component of the sorting machine and is composed of 12 spring rollers. Each spring roller is separately installed on the side plate 305 and is not associated with each other. The tail end of each spring roller 103 is provided with a sprocket. The rotation of the chain is driven by the motor driving the total sprocket, and then the tail end sprocket of all spring rollers 103 is driven. Therefore, each spring roller 103 can be moved and adjusted according to the actual needs, so as to achieve the purpose of adjusting the distance between every two adjacent spring rollers 103. This structure can be steplessly adjusted according to the size and shape of the actual potato seed potatoes, has high adjustment precision, and improves the sorting precision. Therefore, the whole spring roller group can be divided into a non-cutting potato sorting area, a small potato sorting area and a medium potato sorting area according to the size of the gap.

[0056] As shown in Figure 4 The rubber finger roller 110 is a cylindrical body with a square hole in the middle. Eight rubber fingers are uniformly distributed on the outer surface of the cylindrical body. The direction of the rubber fingers coincides with the tangent of the surface of the cylindrical body, which belongs to the structure of imitating fingers. The movement direction of the rubber fingers is the tangent direction of the rotation shaft, which is consistent with the movement direction of the potato. A plurality of rubber finger rollers 110 are arranged in the same axial direction, and the rubber fingers have a fixed gap. The advantage of the rubber finger structure is that the imitating finger structure has a good pushing effect on the incoming potato, which makes the potato pass through the sorting channel more smoothly and reduces the accumulation of the incoming material. Moreover, the rubber fingers have a fixed distance, which is equivalent to setting a fixed length and width space between the rubber finger rollers on the same shaft. Compared with the spring roller group, the advantage is that the sorting conditions are more complete, which can improve the sorting precision and indirectly improve the rationality and uniformity of the potato cutting.

[0057] In the embodiment, the potato cutting device 2 comprises a driving motor 201, side support plates 202, a conical roller conveyor belt and disc cutters 203. The conical roller conveyor belt is arranged between the two side support plates 202 and supported by the two side support plates 202. The disc cutters 203 are arranged on the top of the conical roller conveyor belt for cutting the seed potatoes conveyed by the conical roller conveyor belt. The leading end of the conical roller conveyor belt is connected to the trailing end of the small potato conveyor belt 107, and the trailing end of the conical roller conveyor belt is connected to the leading end of the transfer conveyor belt two 7. The trailing end of the transfer conveyor belt two 7 is connected to the seed mixing conveyor belt 5 for feeding the seed mixing device 4.

[0058] The conical roller conveyor belt comprises a plurality of groups of centering conveying rollers. Each group of centering conveying rollers comprises a long conical nylon roller 204 in the middle and two half-conical nylon rollers 205 on the sides. The long conical nylon roller 204 and the half-conical nylon rollers 205 in each group of centering conveying rollers are supported by the same support shaft. The tapered ends on both sides of the long conical nylon roller 204 are respectively opposite to the tapered ends on the inner sides of the two half-conical nylon rollers 205 to form two centering conveying grooves 206. The outer sides of the two half-conical nylon rollers 205 are provided with square connecting blocks 207 mounted on the support shaft. The square connecting blocks 207 on both sides of each group of centering conveying rollers are connected by connecting members to two single-sided bent plate chains 208, respectively.

[0059] The inner side of one side support plate 202 is provided with an annular guide groove, and the inner side of the other side support plate 202 is provided with an annular rack mounted by connecting members. One side of the support shaft is rotatably connected to the annular guide groove, and the other side of the support shaft is provided with a gear 209. The gear 209 is engaged with the annular rack. The driving motor 201 drives the annular chain to move through a chain wheel one 210. The disc cutters 203 are arranged in two and mounted on a cutter shaft 211. The two disc cutters 203 are respectively opposite to the two centering conveying grooves 206. The two ends of the cutter shaft 211 are supported by mounting plates 212 mounted on the outer sides of the side support plates 202. One end of the cutter shaft 211 is connected to a chain wheel two 213, and the chain wheel two 213 is drivingly connected to the chain wheel one 210 through a transmission chain 214.

[0060] The small potato cutting device 2 is mainly responsible for cutting small potatoes into two parts by using a disc cutter. When working, the conical roller conveyor belt is driven by the motor-driven chain wheel, and the rotation of the chain controls the rotation of the entire conveyor belt. At the same time, the relative motion between the gear 209 and the rack ensures that the conical roller rotates while self-rotating, which is beneficial to the orderly arrangement of small potatoes on the conveyor belt and improves the cutting effect of small potatoes. The gap between the two disc cutters 203 and the conical roller conveyor belt is less than 5 mm, and the cutting surface of the disc cutter 203 is parallel to the movement direction of the conical roller conveyor belt. When the small potatoes move to the small potato cutting device 2, they will be laid flat under the self-rotation of the conical roller. Because two centering conveying grooves 206 are formed between the long conical nylon roller 204 and the half-conical nylon roller 205, the small potatoes will be orderly concentrated in the centering conveying groove 206 and move forward along the conical roller conveyor belt. When moving to the bottom of the high-speed rotating disc cutter 203, the small potatoes will be cut into two parts due to the forward pushing effect and fall onto the transfer conveyor belt two 7 at the output end of the small potato cutting device 2.

[0061] In the specific embodiment, the medium potato mechanical arm cutting device 3 includes a flow guide platform 31 and a mechanical arm cutting platform 32. The first end of the flow guide platform 31 is connected to the end of the medium potato conveyor belt 108, the end of the flow guide platform 31 is connected to the first end of the mechanical arm cutting platform 32, and the end of the mechanical arm cutting platform 32 is connected to the seed mixing conveyor belt 5. The flow guide platform 31 includes a flow guide conveyor belt 301, flow guide plates 302, a flow guide plate rack 303, and legs 304. The legs 304 are used to support the flow guide conveyor belt 301. The flow guide plates 302 are arranged above the first end of the flow guide conveyor belt 301. The flow guide plates 302 are arranged in multiple groups. The flow guide plates 302 are horizontally distributed on the top of the flow guide conveyor belt 301, and the plate body of each flow guide plate 302 is arranged along the conveying direction of the flow guide conveyor belt 301. A flow guide channel is formed between every two flow guide plates 302. The flow guide plate rack 303 is connected to the side plates 305 arranged on both sides of the flow guide conveyor belt 301, and the bottom of the flow guide plate rack 303 is connected to the flow guide plates 302. Specifically, two flow guide plates 302 form a group, and there are three groups in total. Three channels are formed between the groups, which guide and separate all the medium potatoes. Through the guiding effect of the flow guide platform 31, the potato flow passing through the flow guide platform 31 is divided into three columns and moves to the mechanical arm cutting platform 32. The rotating speed of the cutting conveyor belt 306 in the mechanical arm cutting platform 32 is greater than that of the flow guide conveyor belt 301 of the flow guide platform 31. When the divided potato flow moves to the mechanical arm cutting platform 32, the distance between the front and rear potatoes will be increased due to the speed difference, so as to ensure that the potatoes do not affect each other during cutting.

[0062] In the embodiment, the mechanical arm cutting platform 32 comprises a cutting conveyor belt 306, a support 307, a spider-shaped mechanical arm 308, a cutting knife 309, and a camera recognition system 310. The spider-shaped mechanical arm 308 is supported on the top of the cutting conveyor belt 306 through the support 307, the cutting knife 309 is arranged at the bottom of the spider-shaped mechanical arm 308, the spider-shaped mechanical arm 308 cuts the seed potatoes conveyed by the cutting conveyor belt 306, and the camera recognition system 310 is supported on the top of the cutting conveyor belt 306 by a camera support frame 311 arranged at the front end of the spider-shaped mechanical arm 308.

[0063] In the embodiment, the cutting knife 309 comprises a blade 3091, a reinforcing rod 3092, and a cutter disc 3094. The blade 3091 is provided with a hollowed-out surface-reducing hole 3093, the reinforcing rod 3092 is arranged in the surface-reducing hole 3093, the blade 3091 is arranged at the bottom of the cutter disc 3094, and the cutter disc 3094 is used to be connected with the spider-shaped mechanical arm 308. By arranging the surface-reducing hole 3093 and the reinforcing rod 3092 in the surface-reducing hole 3093, the contact area with the cutting surface of the potato is reduced while the strength is ensured, the phenomenon of the cutting knife being stuck during the cutting process is reduced, the collision between the potatoes caused by the potatoes being lifted due to the cutting knife being stuck is avoided, the positioning of the potatoes is affected, the mutual influence between the potatoes during the cutting by the mechanical arm is reduced, and the accuracy and uniformity of the cutting are improved. The cutter disc 3094 is provided with a flange hole, and the cutter disc 3094 is connected with the flange at the bottom of the spider-shaped mechanical arm 308 through the flange hole.

[0064] The cutting knife 309 in the embodiment comprises three shapes, namely a Y-shaped cutter, a cross-shaped cutter, and a six-equal-part cutter, and the corresponding cutter can be selected flexibly according to the size of the potato.

[0065] As shown in Figure 9 , the blade 3091 of the Y-shaped cutter is provided with three blades, which are uniformly distributed around the axis of the cutter disc 3094, and the inner sides of the three blades are welded together to form a Y-shaped cutter. The shape of the blade 3091 is a right-angled triangle, the hypotenuse of the blade 3091 is an arc-shaped concave, the long straight edges of the three blades 3091 are welded together, and the top of each of the three blades 3091 is welded and connected with the cutter disc 3094. The Y-shaped cutter can be used for cutting the relatively small potatoes, and the potato is divided into three parts.

[0066] As shown in Figure 10As shown, the blade 3091 of the cross-shaped cutter is provided with 4, and is evenly distributed with the axis of the cutter head 3094 as the center, and the inner side of the 4 blades 3091 is welded together to form a cross-shaped cutter; the shape of the blade 3091 is a right triangle, and the hypotenuse of the blade 3091 is an arc-shaped concave, the long straight angle edge of the 4 blades 3091 is welded together, and the top of the 4 blades 3091 is welded and connected with the cutter head 3094; the cross-shaped cutter can divide the larger size potato into 4 equal parts.

[0067] As shown in the figure, Figure 11 As shown, the blade 3091 of the six-equal-part cutter is provided with 3, the shape of the blade 3091 is an isosceles triangle, and the waist of the blade 3091 is an arc-shaped concave, among which two blades 3091 are vertically provided with a strip-shaped sleeve hole 3095 in the middle of the blade surface, and the other blade 3091 passes through the sleeve hole 3095 on the two blades 3091 with sleeve hole 3095 respectively, so that the two blades 3091 with sleeve hole 3095 are straddled on the other blade 3091 and fixed by welding, and the top of the three blades 3091 is welded and connected with the cutter head 3094; the combination of the three blades 3091 can form a six-equal-part cutter, which is a standby cutter. If the size of the seed potato is relatively large, the Y-shaped cutter can be replaced to achieve the purpose of uniform cutting

[0068] The above-mentioned reinforcing rods 3092 are all round rods, the reinforcing rods 3092 are vertically arranged and welded with the blade 3091, and a plurality of reinforcing rods 3092 are arranged in the inner space of each reducing hole 3093; the reinforcing rods 3092 can ensure the strength of the blade 3091 after the hole is opened. The blade 3091 and the reinforcing rod 3092 are both made of stainless steel.

[0069] The 3D camera in the camera recognition system 310 can collect the 3D information and relative coordinate information of the passing potato, analyze the size, center of gravity, and movement speed and relative position of the potato through program software, and guide the spider robot arm 308 to act downward, so as to cut the potato into seed pieces with relatively uniform size; during this period, the analysis software analyzes the size of the potato, and classifies the potato into 3 equal parts or 4 equal parts or 6 equal parts according to the size, and then controls the front and rear two spider robot arms 308 to cut the seed potatoes of different sizes.

[0070] Since the mechanical arm front-end camera can collect the 3D information of the incoming potato, the size of the center of gravity of the potato can be analyzed to control the falling size of the mechanical arm end cutter, so as to avoid damaging the belt.

[0071] Below the robotic arm's cutting platform 32 is a liquid storage tank for storing disinfectant. A hose and nozzle are fixed to the end of the robotic arm, spraying directly toward the cutting blades 309. Disinfectant is sprayed onto the blades at a fixed frequency, and the blades can also rotate at a set frequency according to program settings to ensure uniform spraying and complete disinfection of the entire blade. A disinfectant scraper is fixed below the belt, and a disinfectant recovery device is located at the corresponding bottom end, allowing disinfectant on the belt to be recovered and keeping the belt surface dry to reduce the impact of surface reflections on camera recognition.
