Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting equipment, in particular to a potato planting machine with adjustable spacing. Background Art

[0002] In the field of agricultural production, potato planting machines are key equipment for achieving efficient potato planting. Its main function is to complete a series of operations such as furrowing, sowing, and covering the soil during the planting process, and accurately plant potato seeds into the soil at a certain spacing and depth. This equipment is widely used in large-scale potato planting farms and farmers' production activities, and plays an important role in improving potato planting efficiency, reducing farmers' labor intensity, and ensuring potato yield and quality.

[0003] However, traditional potato planters have many shortcomings. In terms of planting accuracy, it is difficult to achieve adaptive fit with the land surface, and the planting depth is greatly affected by the flatness of the land, resulting in different potato planting depths, affecting the consistency of subsequent growth and yield. The planting spacing is inconvenient to adjust, and complex mechanical structures or manual adjustment methods are often used. The operation is cumbersome, time-consuming and labor-intensive, and it is difficult to meet the requirements for rapid adjustment of spacing under different planting needs. In addition, during the sowing process, the seed sowing accuracy of traditional planters is poor, and seeds are prone to leakage or clogging of the injection pipe, resulting in seed waste and uneven planting. In the soil covering stage after planting, manual assistance is usually required, and integrated operations cannot be achieved, which reduces the overall planting efficiency and makes it difficult to adapt to the development trend of large-scale and efficient modern agriculture.

When potatoes need to be planted, the device can be moved to a designated location, and then the device is driven to move continuously in the field. When the device moves through the moving wheel, the rotating shaft will start to rotate, and the rotation of the rotating shaft will prompt the No. 1 transmission belt to start to rotate. When the No. 1 transmission belt starts to rotate, it will drive the No. 1 rotating rod to start to rotate. Through the rotation of the No. 1 rotating rod, the wheel-shaped structure composed of the No. 1 plug-in rod and the No. 2 plug-in rod rolls in the planting area, and the potato seeds are sown into the soil through the injection pipe on the planting component to complete the planting.

[0014] The present invention provides a potato planting machine with adjustable spacing, which has the following beneficial effects: (I) In the potato planting machine with adjustable spacing, since the No. 1 rotating rod is connected to the top plate through an elastic telescopic plate, the wheel-shaped mechanism composed of the No. 1 plug-in rod and the No. 2 plug-in rod is always pressed and fitted on the ground surface under the action of elastic force, thereby completing the adaptive fit between the soil and the plant, avoiding the problem of difficulty in controlling the planting depth of potatoes due to excessive or weak squeezing force, and greatly improving the planting accuracy of potatoes. When it is necessary to reduce the planting spacing of potatoes, the adjusting rod can be pulled outward. As the adjusting rod moves, the internal cavity of the No. 1 rotating rod will gradually increase, thereby causing the interior to be in a negative pressure state, and air pressure will be extracted from the No. 1 telescopic rod through the connecting groove, thereby causing the No. 1 telescopic rod to begin to shrink, thereby causing the diameter of the wheel-shaped structure composed of the No. 1 plug-in rod and the No. 2 plug-in rod to gradually decrease, thereby completing the planting spacing of potatoes. The planting spacing can be quickly adjusted through a simple pull-out structure, greatly reducing the difficulty of use and accelerating the planting efficiency.

[0015] (ii) The potato planting machine with adjustable spacing, when the potato seeds are continuously planted in the soil, the No. 2 rotating rod starts to rotate following the No. 1 rotating rod through the connection of the No. 2 transmission belt, and the rotation speed of the No. 2 rotating rod is faster than that of the No. 1 rotating rod through the differential setting, that is, the rotation speed of the extrusion plate is slightly faster than that of the planting component, and the adjustment rod is controlled before planting so that the diameter of the wheel structure composed of the No. 3 plug-in rod and the No. 4 plug-in rod is larger than that of the No. 1 plug-in rod and the No. 2 plug-in rod, so that the extrusion plate is always aligned with the pit planted by the planting mechanism when it contacts the ground, thereby realizing that after the potato seeds are planted, the planting pit is automatically moved and filled with soil and smoothed by the differentially rotating extrusion plate, thereby realizing rapid integrated planting, avoiding the problem of subsequent manual filling of soil, and greatly improving the planting efficiency.

[0016] (III) When the squeezing plate of the potato planting machine with adjustable spacing contacts and squeezes the ground surface, it will be deformed due to the squeezing force, and then squeeze the squeezing bag on its inner surface, prompting the squeezing bag to inject its internal cavity into the expansion bag, causing the expansion bag to start to expand, thereby driving the connecting plate to move into the storage box through the expansion bag. Prior to this, the potato seeds have entered the interior of the closed tube, and as the storage box rotates, they pass through the leakage trough and enter the temporary storage trough. At this time, as the connecting plate moves, the closed tube is driven to move into the storage box, thereby opening the outer end of the injection tube, allowing the potato seeds to be released through the outer end of the injection tube to complete the seeding, and when the squeezing plate gradually loses contact with the ground, the closed tube resets itself to complete the blocking of the injection tube. By cooperating with the post-processing mechanism, the injection tube is in a closed state when entering the soil, and automatically opens after entering the soil to complete the sowing of seeds, thereby avoiding the problem that the injection tube is always in an open state and causes leakage of seeds. At the same time, it can also avoid the problem that the outer end opening of the injection tube is blocked by soil when entering the soil, resulting in the failure to successfully release the seeds. The buffer groove and the rubber ring cooperate with each other, so that the temporary storage groove has a certain expansion when the closed tube moves into the injection tube, thereby avoiding the problem that too many seeds are stored in the temporary storage groove and the closed tube cannot be effectively extended and retracted. The reset elastic force of the rubber ring can also automatically vibrate and clean the interior of the temporary storage groove, thereby avoiding the problem that seeds are stuck in the temporary storage groove for a long time and cause blockage of the injection tube.

[0027] Second embodiment: Figures 1 to 8As shown, the post-processing mechanism 6 includes a second rotating rod 61, which is rotatably connected to the bottom of the tail elastic telescopic plate 51, and the outer surface of the end of the first rotating rod 52 away from the first transmission belt 53 is rotatably connected to the second transmission belt 62, and the end of the second transmission belt 62 away from the first rotating rod 52 is rotatably connected to the outer surface of the second rotating rod 61, wherein a differential is set between the first rotating rod 52 and the second rotating rod 61, and the outer surfaces of the two ends of the second rotating rod 61 are symmetrically fixedly connected There is a No. 2 ring 63, which is arranged on the inner side of the elastic telescopic plate 51. The outer surface of the No. 2 ring 63 is also fixedly connected to the No. 2 telescopic rod 64. The outer end of the No. 2 telescopic rod 64 is fixedly connected to the No. 3 plug-in rod 65. The two ends of the No. 3 plug-in rod 65 are slidably plugged with the No. 4 plug-in rod 66. The combination of the No. 3 plug-in rod 65 and the No. 4 plug-in rod 66 is the same as the No. 1 plug-in rod 56 and the No. 2 plug-in rod 57. The internal structure of the No. 2 rotating rod 61 is the same as the No. 1 rotating rod 52.

[0028] The inner surface of the No. 3 plug-in rod 65 is fixedly connected with a positioning plate 67, which is arranged in an arc shape. The outer surface of the positioning plate 67 is fixedly connected with an extrusion bag 68. The internal cavity of the extrusion bag 68 is connected to the expansion bag 520. The outer surface of the extrusion bag 68 is fixedly connected with an extrusion plate 69, which is arranged in an arc shape. The outer end of the extrusion plate 69 protrudes from the setting of the No. 3 plug-in rod 65, and the inner end of the extrusion plate 69 is fixedly connected to the outer surface of the positioning plate 67.

[0029] During operation, when it is necessary to plant potatoes, the device can be moved to a designated location, and then driven to move continuously in the field. When the device is moved by the moving wheel 4, the rotating shaft 3 will start to rotate. As the rotating shaft 3 rotates, the No. 1 transmission belt 53 will start to rotate. When the No. 1 transmission belt 53 starts to rotate, the No. 1 rotating rod 52 will start to rotate. The rotation of the No. 1 rotating rod 52 makes the wheel structure composed of the No. 1 plug-in rod 56 and the No. 2 plug-in rod 57 roll in the planting area, and the potato seeds are sown into the soil through the injection pipe 514 on the planting component 58 to complete the planting. Since the No. 1 rotating rod 52 is connected to the top plate 1 through the elastic telescopic plate 51, the No. 1 plug-in rod 56 and the No. 2 plug-in rod 57 are connected to the top plate 1 through the elastic telescopic plate 51. The wheel-shaped mechanism composed of the plug-in rods 57 is always pressed and fitted to the soil surface under the action of elastic force, thereby completing the adaptive fit with the soil, avoiding the problem of difficulty in controlling the planting depth of potatoes due to excessive or weak squeezing force, and greatly improving the planting accuracy of potatoes. When it is necessary to reduce the planting distance of potatoes, the adjusting rod 59 can be pulled outward. As the adjusting rod 59 moves, the internal cavity of the No. 1 rotating rod 52 will gradually increase, thereby making the interior thereof in a negative pressure state, and air pressure will be extracted from the inside of the No. 1 telescopic rod 55 through the connecting groove 510, thereby causing the No. 1 telescopic rod 55 to begin to shrink, thereby causing the diameter of the wheel-shaped structure composed of the No. 1 plug-in rod 56 and the No. 2 plug-in rod 57 to gradually decrease, thereby completing the potato planting. The planting spacing can be quickly adjusted through a simple pull-out structure, which greatly reduces the difficulty of use and speeds up planting efficiency. At this time, when the potato seeds are continuously planted in the soil, the No. 2 rotating rod 61 follows the No. 1 rotating rod 52 through the connection of the No. 2 transmission belt 62 to start rotating, and the No. 2 rotating rod 61 rotates faster than the No. 1 rotating rod 52 through the differential setting, so that the rotation speed of the extrusion plate 69 is slightly faster than the planting component 58, and before planting, the adjustment rod 59 is controlled to make the wheel structure composed of the No. 3 plug-in rod 65 and the No. 4 plug-in rod 66 have a larger diameter than the No. 1 plug-in rod 56 and the No. 2 plug-in rod 57, so that the extrusion plate 69 is always aligned with the pit planted by the planting mechanism 5 when it contacts the ground, thereby achieving After the potato seeds are planted, the differentially rotating squeezing plate 69 automatically moves the planting pit to fill and smooth the soil, thereby achieving rapid integrated planting and avoiding the need for manual soil filling in the future. This greatly improves the planting efficiency. When the squeezing plate 69 contacts and squeezes the soil surface, it will deform due to the squeezing force, thereby squeezing the squeezing bag 68 on its inner surface, causing the squeezing bag 68 to inject its internal cavity into the expansion bag 520, causing the expansion bag 520 to begin to expand, thereby driving the connecting plate 519 to move into the storage box 513 through the expansion bag 520. Prior to this, the potato seeds have entered the interior of the closed tube 517, and as the storage box 513 rotates, they enter the temporary storage tank 515 through the leakage trough 518.At this time, as the connecting plate 519 moves, the closing tube 517 will be driven to move into the storage box 513, thereby opening the outer end of the injection tube 514, allowing the potato seeds to be released through the outer end of the injection tube 514 to complete the sowing of the seeds, and when the squeezing plate 69 gradually breaks away from the contact with the ground, the closing tube 517 will reset itself to complete the blockage of the injection tube 514, and through the mutual cooperation with the post-processing mechanism 6, the injection tube 514 is in a closed state when entering the soil, and automatically opens after entering the soil to complete the sowing of the seeds, thereby avoiding the problem that the injection tube 514 is always in an open state and causes leakage of seeds. At the same time, it can also avoid the problem that the outer end opening of the injection tube 514 is blocked by soil when entering the soil, resulting in the failure of the seeds to be successfully released. The buffer groove 521 and the rubber ring 522 cooperate with each other, so that the closed tube 517 can make the temporary storage groove 515 have a certain expansion when moving into the injection tube 514, thereby avoiding the problem that too many seeds are stored in the temporary storage groove 515 and the closed tube 517 cannot be effectively expanded and contracted. The resetting elastic force of the rubber ring 522 can also automatically vibrate and clean the interior of the temporary storage groove 515, avoiding the problem that the seeds stick to the temporary storage groove 515 for a long time and cause the injection tube 514 to be blocked.
