Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a seedling transplanting soil covering structure. Background Art

[0002] Transplanting seedlings with soil balls is a common transplantation method. Choose healthy seedlings with well-developed root systems when transplanting. Water appropriately before transplanting to ensure that the soil is moist to facilitate digging the soil ball. When digging the soil ball, pay attention to maintaining the integrity of the root system and the soil ball. When transplanting, place the soil ball directly into the dug hole.

[0003] In order to improve the efficiency of transplanting seedlings with soil balls, there is currently a transplanter for transplanting seedlings with soil balls. The transplanter includes an outer cylinder, a fixed handle fixed on the upper side of the outer cylinder, and a sliding handle that passes through the fixed handle and is slidably connected to the fixed handle. The sliding handle is arranged through the fixed handle and can slide in a vertical direction. A pushing ring is also arranged at the lower end of the sliding handle. A cutting edge is arranged at the lower end port of the outer cylinder. When transplanting, a hole to be transplanted is first dug directly at the transplanting position with the outer cylinder. When transplanting, the seedlings are directly dug out together with the soil ball through the outer cylinder. Then, the sliding handle and the pushing ring are pushed, so that the dug seedlings with the soil ball can be transplanted exactly into a hole of the same size as the soil ball.

[0004] The above-mentioned seedling transplanting equipment can only complete the simple transplanting process of seedlings, that is, it can only dig out the seedlings with soil balls from the original position and transfer them to the pits at the transplanting position. After transplanting, the base of the seedlings (the place where the roots and stems of the seedlings are connected) is exposed to the external environment. When the base of the seedlings is not protected by soil, it is easy for the roots of the seedlings to be invaded by pests and diseases, or it is easy to cause the seedlings to tilt or fall over when encountering wind and rain, which is not conducive to the healthy growth of the seedlings. Summary of the invention

[0005] The purpose of the invention is to provide a seedling transplanting soil covering structure, which can cover the soil on the base of the seedlings synchronously while transplanting the seedlings.

[0006] The technical solution adopted by the present invention is a seedling transplanting soil covering structure, comprising an outer cylinder and a fixed handle, wherein the fixed handle comprises a first vertical rod fixedly connected to the upper end of the outer cylinder, and the upper end of the first vertical rod away from the outer cylinder is further connected to a horizontal first cross rod, characterized in that it also comprises:

[0007] The inner cylinder is coaxially arranged inside the outer cylinder, an annular cavity is formed between the inner cylinder and the outer cylinder, and a second vertical rod for fixing the inner cylinder is fixedly arranged between the inner cylinder and the first cross rod;

[0008] The soil covering unit includes a third vertical rod that is perpendicular to the first horizontal rod and slidably connected to the first horizontal rod. The third vertical rod passes through the first horizontal rod and a ring-shaped soil covering plate is arranged at the lower end thereof. The soil covering plate is arranged correspondingly on the upper side of the annular cavity. After the seedlings are transplanted, the third vertical rod is slid downward and drives the soil covering plate to slide downward, and then the soil covering plate can cover the soil in the annular cavity around the seedlings.

[0009] A horizontal second cross plate is arranged at the lower end of the third vertical rod, a covering plate is arranged at one end of the second cross plate through a first connecting rod, and an annular bulldozer plate is arranged at the other end of the second cross plate through a second connecting rod, and the bulldozer plate is arranged correspondingly on the upper side of the inner cylinder.

[0010] A first scraping ring and a second scraping ring in an annular shape are arranged downward on the soil covering plate. The upper end of the first scraping ring is connected to the outer ring of the soil covering plate, and the second scraping ring is connected to the inner ring of the soil covering plate.

[0011] The vertical cross-section of the cavity formed by the earth-sealing plate, the first scraper ring and the second scraper ring is in a trapezoidal shape at a section passing through the axis of the outer cylinder.

[0012] The first scraper ring and the second scraper ring are both provided with scraper blades at one end away from the soil covering plate, and the scraper blades are in contact with the inner wall of the outer cylinder and the outer wall of the inner cylinder respectively.

[0013] The lower end port of the outer cylinder is provided with a first cutting edge.

[0014] The lower end port of the inner cylinder is provided with a second cutting edge.

[0015] The heights of the outer cylinder and the inner cylinder are the same, and the length of the third vertical rod is greater than the heights of the outer cylinder and the inner cylinder.

[0016] The beneficial effects of the present invention are:

[0017] When the seedling transplanting soil covering structure disclosed by the present invention is used, the inner cylinder is aligned with the seedlings to be transplanted, and then the first cross bar at the upper end of the fixed handle is held by hand and the entire structure is inserted downward into the soil. While inserting, the soil is cut by the joint action of the outer cylinder and the inner cylinder, and the seedlings are dug at the same time. When the required depth is reached, the entire structure is lifted upward, and then the inner cylinder will dig out the seedlings and the soil ball with their roots, and at the same time, sufficient soil is embedded in the annular cavity formed between the inner cylinder and the outer cylinder, and this part of the soil can be used as the soil surface and around the seedlings later. As covering soil, during subsequent transplanting, first use an excavation tool of the same size as the inner cylinder to dig a transplanting hole, then align the entire structure downward with the newly dug hole, and under the action of gravity, the seedling with the soil ball will accurately fall into the dug hole and complete the first step of transplanting, then push the third vertical rod to slide downward, and while the third vertical rod slides downward, it also drives the covering soil plate to slide downward, so that the soil in the annular cavity can be pushed out and this part of the soil falls just around the seedling, and then the covering soil at the base of the seedling can be completed by simply shaping this part of the soil through the covering soil plate.

DETAILED DESCRIPTION

[0022] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0023] Transplanting seedlings with soil balls is a common transplantation method. Choose healthy seedlings with well-developed root systems when transplanting. Water appropriately before transplanting to ensure that the soil is moist to facilitate digging the soil ball. When digging the soil ball, pay attention to maintaining the integrity of the root system and the soil ball. When transplanting, place the soil ball directly into the dug hole.

[0024] In order to improve the efficiency of transplanting seedlings with soil balls, there is currently a transplanter for transplanting seedlings with soil balls. The transplanter includes an outer cylinder, a fixed handle fixed on the upper side of the outer cylinder, and a sliding handle that passes through the fixed handle and is slidably connected to the fixed handle. The sliding handle is arranged through the fixed handle and can slide in a vertical direction. A pushing ring is also arranged at the lower end of the sliding handle. A cutting edge is arranged at the lower end port of the outer cylinder. When transplanting, a hole to be transplanted is first dug directly at the transplanting position with the outer cylinder. When transplanting, the seedlings are directly dug out together with the soil ball through the outer cylinder. Then, the sliding handle and the pushing ring are pushed, so that the dug seedlings with the soil ball can be transplanted exactly into a hole of the same size as the soil ball.

[0025] The above-mentioned seedling transplanting equipment can only complete the simple transplanting process of seedlings, that is, it can only dig out the seedlings with soil balls from the original position and transfer them to the pits at the transplanting position. After transplanting, the base of the seedlings (the place where the roots and stems of the seedlings are connected) is exposed to the external environment. When the base of the seedlings is not protected by soil, it is easy for the roots of the seedlings to be invaded by pests and diseases, or it is easy to cause the seedlings to tilt or fall over when encountering wind and rain, which is not conducive to the healthy growth of the seedlings.

[0026] Covering the base of the seedlings with soil has the following benefits: 1. Covering the base of the seedlings with soil can help the roots of the seedlings take root better, so as to absorb more water and nutrients; 2. Mounding the soil can retain the moisture of the soil, which helps the seedlings survive in drought conditions; 3. Covering the soil can inhibit the growth of weeds and reduce resource competition; 4. Covering the soil can inhibit the growth of weeds and reduce resource competition. Therefore, covering the base of the seedlings with soil after transplanting helps the normal growth of the seedlings.

[0027] The present invention discloses a seedling transplanting soil covering structure, such as Figure 1-3 As shown, it includes: an outer cylinder 1, a fixed handle 2, an inner cylinder 3 and a soil sealing unit; wherein the fixed handle 2 includes a first vertical rod 3 fixedly connected to the upper end of the outer cylinder 1, and the upper end of the first vertical rod 3 away from the outer cylinder 1 is also connected to a horizontal first cross bar 4; the inner cylinder 5 is coaxially arranged on the inner side of the outer cylinder 1, and an annular cavity is formed between the inner cylinder 5 and the outer cylinder 1, and a second vertical rod 6 is fixedly arranged between the inner cylinder 5 and the first cross bar 4; the soil sealing unit includes a third vertical rod 7 perpendicular to the first cross bar 4 and slidably connected to the first cross bar 4, the third vertical rod 7 passes through the first cross bar 4 and an annular soil sealing plate 8 is arranged at its lower end, and the soil sealing plate 8 is correspondingly arranged on the upper side of the annular cavity. After the seedlings are transplanted, the third vertical rod 7 is slid downward and drives the soil sealing plate 8 to slide downward, and then the soil sealing plate 8 can cover the soil in the annular cavity around the seedlings.

[0028] When the seedling transplanting soil covering structure disclosed in the present invention is used, the inner cylinder 5 is aligned with the seedlings to be transplanted, and then the first cross bar 4 at the upper end of the fixed handle 2 is held by hand and the entire structure is inserted downward into the soil. While inserting, the soil is cut and the seedlings are dug at the same time through the joint action of the outer cylinder 1 and the inner cylinder 3. When the required depth is reached, the entire structure is lifted upward, and then the seedlings and the soil ball are dug out with their roots on the inside of the inner cylinder 5, and at the same time, sufficient soil is embedded in the annular cavity formed between the inner cylinder 5 and the outer cylinder 1, and this part of the soil can be used as the soil surface and around the seedlings later. The inner cylinder 3 is used as covering soil. During subsequent transplanting, first use an excavation tool of the same size as the inner cylinder 3 to dig a transplanting hole, then align the entire structure downward with the newly dug hole, and under the action of gravity, the seedling with the soil ball accurately falls into the dug hole and completes the first step of transplanting. Then, push the third vertical rod 7 to slide downward. While the third vertical rod 7 slides downward, it also drives the covering soil plate 8 to slide downward, so that the soil in the annular cavity can be pushed out and this part of the soil falls just around the seedling. Then, the covering soil plate 8 is used to simply shape this part of the soil to complete the covering soil at the base of the seedling when transplanting the seedling.

[0029] Furthermore, the lower end of the third vertical rod 7 disclosed in the present embodiment is provided with a horizontal second horizontal plate 10, the earth-covering plate 8 is provided at one end of the second horizontal plate 10 through the first connecting rod 9, and the other end of the second horizontal plate 10 is provided with an annular bulldozer plate 12 through the second connecting rod 11, and the bulldozer plate 12 is correspondingly provided on the upper side of the inner cylinder 5. When the third vertical rod 7 is pushed to slide downward, the second horizontal plate 10, the second connecting rod 11 and the bulldozer plate 12 can be driven to slide downward at the same time, and in this process, the bulldozer plate 12 can push the seedling, i.e. the soil ball with it, to slide downward, thereby avoiding the situation that the soil ball adheres to the inner side of the inner cylinder 5 and causes poor transplanting.

[0030] The soil cover plate 8 disclosed in this embodiment is provided with a first scraping ring 13 and a second scraping ring 14 which are downward and in an annular shape, the upper end of the first scraping ring 13 is connected to the outer ring of the soil cover plate 8, and the second scraping ring 14 is connected to the inner ring of the soil cover plate 8. The first scraping ring 13 and the second scraping ring 14 can scrape away the soil attached to the inner wall of the outer cylinder 1 and the outer wall of the inner cylinder 1 as the soil cover plate 8 slides downward, so that the soil attached to the annular cavity can completely fall around the seedlings and cover the seedlings each time the seedlings are dug, thereby ensuring that there is enough soil to cover the area around the base of the seedlings.

[0031] In practice, the shape of the soil covering around the seedlings is generally a trapezoidal structure. Therefore, the cross-sectional shape of the cavity formed by the soil covering plate 8, the first scraper ring 13 and the second scraper ring 14 disclosed in this embodiment is a trapezoidal cross-section obtained in the vertical section through the axis of the outer cylinder 1. Because when the first scraper ring 13 and the second scraper ring 14 slide downward with the soil covering plate 8, the soil in the annular cavity can also be shaped into a trapezoidal shape under the action of the first scraper ring 13 and the second scraper ring 14, which facilitates the subsequent soil covering work. Finally, when the trapezoidal soil that has been covered by the first scraper ring 13 and the second scraper ring 14 falls on the soil surface around the seedlings, the soil can be covered around the base of the seedlings by simple shaping, which is conducive to the normal growth of the seedlings.

[0032] The first scraper ring 13 and the second scraper ring 14 disclosed in this embodiment are both provided with a scraper blade 17 at one end away from the soil cover plate 8, and the scraper blade 17 is in contact with the inner wall of the outer cylinder 1 and the outer wall of the inner cylinder 5, respectively. Therefore, the soil attached to the inner wall of the outer cylinder 1 and the outer wall of the inner cylinder 5 can be effectively scraped off by the scraper blade 17.

[0033] The lower end of the outer cylinder 1 is provided with a first cutting edge 15. The lower end of the inner cylinder 5 is provided with a second cutting edge 16. The first cutting edge 15 and the second cutting edge 16 are respectively used to assist the outer cylinder 1 and the inner cylinder 5 to dig downwards.

[0034] The outer cylinder 1 and the inner cylinder 5 have the same height, and the length of the third vertical rod 7 is greater than the height of the outer cylinder 1 and the inner cylinder 5. In this way, when the third vertical rod 7 drives the earth cover plate to slide downward, the soil in the annular cavity between the outer cylinder 1 and the inner cylinder 2 can be completely scraped off to prevent the soil from adhering to the inner wall of the annular cavity.

[0035] In summary, the present invention provides a seedling transplanting soil covering structure. When in use, the inner cylinder 5 is aligned with the seedlings to be transplanted, and then the first cross bar 4 at the upper end of the fixed handle 2 is held by hand and the entire structure is inserted downward into the soil. While inserting, the soil is cut and the seedlings are dug at the same time through the joint action of the outer cylinder 1 and the inner cylinder 3. When the required depth is reached, the entire structure is lifted upward, and then the seedlings and the soil ball are dug out with their roots on the inside of the inner cylinder 5, and at the same time, sufficient soil is embedded in the annular cavity formed between the inner cylinder 5 and the outer cylinder 1. This part of the soil can be used as the soil surface and around the seedlings later. The inner cylinder 3 is used as covering soil. During subsequent transplanting, first use an excavation tool of the same size as the inner cylinder 3 to dig a transplanting hole, then align the entire structure downward with the newly dug hole, and under the action of gravity, the seedling with the soil ball accurately falls into the dug hole and completes the first step of transplanting. Then, push the third vertical rod 7 to slide downward. While the third vertical rod 7 slides downward, it also drives the covering soil plate 8 to slide downward, so that the soil in the annular cavity can be pushed out and this part of the soil falls just around the seedling. Then, the covering soil plate 8 is used to simply shape this part of the soil to complete the covering soil at the base of the seedling when transplanting the seedling.

[0036] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention belong to the protection scope of the present invention.
