Description

Technical Field

[0001] The invention relates to the technical field of seed potato cutting, in particular to a seed potato cutting device for potato planting. Background Art

[0002] In potato planting, cutting seed potatoes into cubes is a common technique. Its main purpose is to promote seed potato germination, early emergence, increase the growth period, and increase yield. At the same time, cutting can also save seed potatoes and reduce production costs. When cutting, healthy and disease-free seed potatoes should be selected, and the size of the cubes should be appropriate. The size of the cubes is generally more than 25 grams, so that each cube can have enough nutrition and water, which is conducive to subsequent growth and development. At the same time, the size of the cubes should be kept consistent as much as possible so that the seedlings can emerge neatly and it is convenient for water and fertilizer management in production.

[0003] In existing potato planting, seed potato cutting mainly relies on manual operation. When cutting manually, farmers need to select healthy and disease-free seed potatoes and use sharp knives to cut them. The size of the cut pieces should be moderate to ensure that each cut piece can provide sufficient nutrition to support the growth of potatoes. At the same time, the shape should be kept as regular as possible so that the seedlings can emerge neatly during planting. However, the above-mentioned existing technologies still have the following defects:

[0004] 1. When cutting seed potatoes manually, it is often difficult to ensure that the size of each piece is completely consistent, which will affect the growth rate and yield of potatoes. Cutting too large may lead to uneven nutrient distribution, while cutting too small may make the seedlings grow weak. Moreover, manual cutting requires a lot of manpower and time, especially in large-scale planting, the labor cost will increase significantly, which not only increases the planting cost, but also may affect the planting efficiency.

[0005] 2. The existing manual cutting is inefficient. In large-scale planting, manual cutting may not meet production needs, resulting in delays in sowing progress. Moreover, when cutting manually, due to differences in operator skill levels, experience and other factors, it is difficult to ensure that the quality of each cut meets the standard, affecting the growth and yield of potatoes. The irregular shape of the cut seed potatoes may affect the efficiency and accuracy of mechanized sowing, fertilization and other operations. Summary of the invention

[0042] Specifically, the operation disk 12 rotates on the central column 11 to drive the potatoes to rotate, the potatoes are cut into pieces by the cutting unit, the cut potatoes are collected by the receiving box 13, the potatoes are cut into pieces by the cutting component, the cut potatoes are collected by the collecting component, the potatoes are pre-cut by the pre-cutting component 2, and the potatoes are cut into two halves, so that the potatoes fall on the operation disk 12, and the cut surface of the potatoes is in contact with the operation disk 12, the operation disk 12 rotates, driving the pre-cut potatoes to rotate, and the potatoes are cut into pieces by the cutting component 3, thereby improving the low efficiency of manual cutting and increasing labor costs, and the swinging component 4 is driven to rotate by the rotating component 5, and the swinging component 4 drives the cutter of the cutting component 3 to swing, so as to improve the low efficiency of manual cutting and increase labor costs. By changing the cutting direction of the cutter, the potatoes are cut evenly, so that each cut potato has buds, thereby improving the survival rate of potato sowing. The potatoes to be cut are put into the feed port 25, so that the potatoes enter the barrel 21 and slide into the bottom of the barrel 21. The first hydraulic cylinder 24 is started to drive the push plate 23 to slide in the barrel 21 to squeeze the potatoes. Under the action of the first cutter 22, the potatoes are cut into two halves. Since the cross-section of the first cutter 22 is a conical structure, the potatoes cut into two halves slide from the conical surface of the first cutter 22 and fall from the bottom of the barrel 21 onto the operating disk 12, and the cut surface of the potatoes fits with the operating disk 12, ensuring that the potatoes will not move when cutting, and the potatoes can be cut into required blocks.

[0043] Reference Figure 4 and Figure 5The cutting assembly 3 includes a first sliding groove 310 opened on the central column 11, a first slider 311 slidably connected to the inner side of the first sliding groove 310, a first frame 31 fixedly connected to the first slider 311, a U-shaped plate 32 fixedly connected to the first frame 31, a swing bar 33 rotatably connected to the first frame 31, a bar hole 36 opened on the swing bar 33, a plug column 34 slidably connected in the bar hole 36, a connecting bar 35 fixedly connected to the plug column 34, a fixed shaft 37 rotatably connected to the U-shaped plate 32, one end of the fixed shaft 37 is fixedly connected to the connecting bar 35, a knife seat 38 fixedly connected to the other end of the fixed shaft 37, and a second cutting knife 39 fixedly connected to the knife seat 38.

[0044] Specifically, the first slider 311 slides in the first slide groove 310, driving the first frame 31 to move, driving the U-shaped plate 32 to move, driving the swing bar 33 to move, driving the plug post 34 to move, driving the connecting bar 35 to move, driving the fixed shaft 37 to move, driving the knife seat 38 to move, and driving the second cutter 39 to move, so as to cut the potatoes into pieces. The second cutter 39 is inclined, and the oblique cutting method is used to cut the potatoes into pieces, thereby improving the quality of the pieces and the uniformity of germination, which is beneficial to promoting the growth of the root system. The swing bar 33 swings, so that the plug post 34 slides in the strip hole 36, driving the connecting bar 35 to rotate, driving the fixed shaft 37, the knife seat 38 and the second cutter 39 to rotate, so that the second cutter 39 is in an inclined state to cut the potatoes into pieces.

[0045] Reference Figure 6 The swing assembly 4 includes a rotating shaft 42 rotatably connected to the first frame 31, a second frame 41 fixedly connected to the rotating shaft 42, a moving block 43 limitedly slidably connected to the second frame 41, a threaded rod 44 threadedly connected to the second frame 41, one end of the threaded rod 44 is located in the second frame 41 and rotatably connected to the moving block 43, a toggle column 45 fixedly connected to the moving block 43, and the toggle column 45 is slidably connected to the inner side of the bar hole 36.

[0046] Specifically, by rotating the rotating shaft 42, the second frame 41 is driven to rotate, the moving block 43 is driven to rotate, and the toggle column 45 is driven to rotate, so that the toggle column 45 slides in the bar hole 36, and the swing bar 33 is driven to swing. By rotating the threaded rod 44, the moving block 43 is driven to move in the second frame 41, and the toggle column 45 is driven to move, so that the distance between the toggle column 45 and the rotating shaft 42 changes, so that the length of the swing arm changes, and then the swing angle of the swing bar 33 changes, so that the swing angle of the second cutter 39 changes, and the cutting angle of the second cutter 39 can be adjusted, so that the second cutter 39 can cut accurately, ensuring that the potatoes after cutting are distributed with eyes, improving the utilization rate of cutting, and helping to increase the yield.

[0047] Reference Figure 7 and Figure 8 The rotating assembly 5 includes a mounting plate 51 fixedly connected to the center column 11, a fixed cylinder 52 fixedly connected to the mounting plate 51, a first spiral groove 57 provided in the fixed cylinder 52, a first vertical groove 58 provided in the fixed cylinder 52 and communicating with the inner side of the first spiral groove 57, a groove 59 provided in the fixed cylinder 52 and communicating with the inner sides of the first spiral groove 57 and the first vertical groove 58, a moving disk 54 slidably connected to the fixed cylinder 52, a trigger rod 55 slidably connected to the moving disk 54, the trigger rod 55 is slidably connected to the inner sides of the first spiral groove 57, the first vertical groove 58 and the groove 59 respectively, a moving column 53 slidably connected to the fixed cylinder 52, one end of the moving column 53 is fixedly connected to the moving disk 54, and the other end of the moving column 53 is fixedly connected to the rotating shaft 42, and a second hydraulic cylinder 56 fixedly connected to the mounting plate 51, and the output end of the second hydraulic cylinder 56 extends into the fixed cylinder 52 and is rotatably connected to the moving disk 54.

[0048] Specifically, the second hydraulic cylinder 56 drives the movable plate 54 to move in the fixed cylinder 52. When the movable plate 54 moves downward in the fixed cylinder 52, the trigger rod 55 slides from the groove 59 into the first vertical groove 58. Under the action of the groove 59 and the first vertical groove 58, the trigger rod 55 moves vertically downward, so that the movable plate 54 moves vertically downward, drives the movable column 53 to move downward, drives the rotating shaft 42 to move downward, drives the swing assembly 4 to move downward, drives the cutting assembly 3 to move downward, drives the second cutter 39 to move downward, and cuts the potatoes into pieces. When the movable plate 54 moves upward in the fixed cylinder 52, the trigger rod 55 slides from the first vertical groove 58 into the first spiral groove 57. Under the action of the first spiral groove 57, the trigger rod 55 rotates during the upward movement, driving the rotating shaft 42 and the movable column 53 to move upward and rotate, and the rotation angle is exactly 180 degrees, driving the swing assembly 4 and the cutting assembly 3 to move upward, so that the second cutter 39 leaves the potato, and rotates 180 degrees through the rotating shaft 42. Under the action of the swing assembly 4, the swing bar 33 rotates, so that the second cutter 39 rotates a certain angle, that is, when the second cutter 39 moves downward, the potato is cut into pieces, and when the second cutter 39 moves upward, it rotates a certain angle, so that the cutting direction of the second cutter 39 changes, and the potato is continuously cut into pieces.

[0049] Example 2, reference Figure 9-13, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cutting component also includes a reset component 6 installed on the rotating component 5, a pulling component 7 installed on the cutting component 3, and a pushing component 8 installed on the cutting component 3; the reset component 6 includes an active cavity 61 opened on the movable disk 54, a trigger rod 55 is slidably connected to the inner side of the active cavity 61, and a reset spring 62 is fixedly connected between the active cavity 61 and the trigger rod 55.

[0050] Specifically, since the first spiral groove 57 is deeper than the first vertical groove 58, the trigger rod 55 slides from the first vertical groove 58 into the first spiral groove 57 from squeezing the reset spring 62 to releasing the reset spring 62. When the trigger rod 55 moves upward, it will not slide upward directly from the first vertical groove 58. Since the groove 59 is deeper than the first spiral groove 57, when the trigger rod 55 slides in the first spiral groove 57, it squeezes the reset spring 62. When it slides from the first spiral groove 57 into the groove 59, the reset spring 62 is squeezed. 9, since the groove 59 is deeper than the first spiral groove 57, the reset spring 62 will reset, so that the trigger rod 55 abuts against the bottom wall of the groove 59, so that the trigger rod 55 slides into the groove 59, and the trigger rod 55 will not slide downward from the first spiral groove 57 when moving downward, that is, when the trigger rod 55 moves upward, it slides from the first vertical groove 58 into the first spiral groove 57, and when the trigger rod 55 moves downward, it slides from the first spiral groove 57 into the groove 59, enters the first vertical groove 58 and moves vertically downward.

[0051] Reference Fig.10 and Fig.11 The pulling assembly 7 includes a connecting shaft 75 rotatably connected to the first frame 31, a winding wheel 76 fixedly connected to one end of the connecting shaft 75, a winding rope 77 wound around the winding wheel 76, a column 72 fixedly connected to the other end of the connecting shaft 75, a second spiral groove 73 provided on the column 72, two second vertical grooves 78 symmetrically distributed on the column 72 and connected to the head and tail of the second spiral groove 73 respectively, an L-shaped rod 71 fixedly connected to the center column 11, and a protrusion 74 fixedly connected to the L-shaped rod 71, and the protrusion 74 is slidably connected to the inner sides of the second spiral groove 73 and the second vertical groove 78 respectively.

[0052] Specifically, when the first frame 31 moves, it drives the connecting shaft 75 to move, drives the column 72 to move, and the L-shaped rod 71 is fixedly connected to the center column 11, so that the protrusion 74 slides in the second spiral groove 73. Under the action of the second spiral groove 73, the column 72 rotates, driving the connecting shaft 75 to rotate, driving the winding wheel 76 to rotate, and winding the winding rope 77. The protrusion 74 slides from the second spiral groove 73 into the second vertical groove 78. Under the action of the second vertical groove 78, the protrusion 74 moves vertically up and down. At this time, the connecting shaft 75 will no longer rotate, so as to prevent the winding rope 77 from being over-wound or over-loosened.

[0053] Reference Fig.12 and Fig.13 The pushing assembly 8 includes a third frame 81 fixedly connected to the knife seat 38, a pushing block 82 limited and slidably connected in the third frame 81, one end of the winding rope 77 away from the winding wheel 76 is fixedly connected to the pushing block 82, a second spring 89 fixedly connected between the pushing block 82 and the third frame 81, a through hole 83 opened in the pushing block 82, a pushing rod 84 limited and slidably connected in the through hole 83, a plug rod 87 slidably connected to the pushing rod 84, a first spring 88 fixedly connected between the plug rod 87 and the pushing rod 84, the first spring 88 is sleeved on the plug rod 87, a second slide groove 811 opened on the pushing rod 84, a second slider 810 limited and slidably connected to the inner side of the second slide groove 811, a connecting rod 85 rotatably connected to the second slider 810, a pushing plate 86 rotatably connected to the connecting rod 85, and the pushing plate 86 is fixedly connected to the plug rod 87.

[0054] Specifically, when the winding rope 77 is wound by the winding wheel 76, the pushing block 82 is pulled to move in the third frame 81, the second spring 89 is stretched, the pushing rod 84 is driven to move, the insertion rod 87 is driven to move, and the pushing plate 86 is driven to move, so that the potatoes cut by the second cutter 39 are pushed away from the second cutter 39. When the pushing block 82 moves in the third frame 81, the third frame 81 also moves upward, so that the pushing rod 84 slides downward in the through hole 83. At the beginning, the connecting rod 85 is close to the pushing rod 84 and is located in the through hole 83. The first spring 88 is stretched, and the third frame 81 moves downward, and the push rod 84 moves downward in the through hole 83, so that the connecting rod 85 slowly slides out of the through hole 83. When the connecting rod 85 slides out of the through hole 83, the first spring 88 will reset, driving the insertion rod 87 to move quickly toward the push plate 86, driving the push plate 86 to bounce away from the push rod 84, so that the second slider 810 slides downward in the second slide groove 811, and then the potato pieces on one side of the second cutter 39 are bounced away, so as to prevent the second cutter 39 from cutting the already cut potato pieces again when the direction is turned, resulting in unqualified potato pieces. The rest of the structure is the same as that of embodiment 1.

[0055] Example 3, reference Figure 1 and Figure 2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the collecting component includes a collecting assembly 9 installed on the central column 11, and a driving assembly 10 installed on the base 1; the collecting assembly 9 includes a top rod 91 fixedly connected to the central column 11, a rotating shaft 92 rotatably connected to the top rod 91, a plurality of collecting plates 93 distributed in a ring array and fixedly connected to the rotating shaft 92, and a pulley 94 fixedly connected to the rotating shaft 92.

[0056] Specifically, the collecting assembly 9 and the operating disk 12 are driven to rotate by the driving assembly 10, and the cut potato pieces are collected by the collecting assembly 9. The pulley 94 rotates to drive the rotating shaft 92 to rotate, and drives the multiple collecting plates 93 to rotate, so that the potato pieces on the operating disk 12 fall into the receiving box 13, and the potato pieces are collected.
