Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a multi-grain pile-type seeding mechanism in a ditch and the integrated machine for pile-planting and fertilizing composed of it. Background Technology

[0002] Sowing is a crucial part of agricultural production. It is essential to sow at the appropriate time according to agronomic requirements to ensure uniform and robust seedling emergence, laying a solid foundation for a bumper harvest. Based on sowing methods, machines can be categorized into broadcast seeders, row seeders, and hill seeders, and further classified as non-precision seeders and precision seeders. Precision seeding focuses on precise control of seed quantity, plant spacing, and sowing depth. This saves seeds, avoids thinning after emergence, ensures uniform nutrient distribution per plant, and allows for single-seed or multi-seed hill sowing.

[0003] Currently, combined operations have become the mainstream to reduce the number of field visits. Fertilizer tanks, fertilizer dispensers, and fertilizer delivery pipes are added to seeders, allowing for simultaneous sowing and fertilization. There are also combined operation machines that integrate soil tillage, watering, pesticide spraying, and mulching, completing multiple tasks in one go, including pre-sowing tillage, fertilizer application, soil disinfection, drainage ditch digging, sowing, pesticide application, and mulching. However, with the overuse of chemical fertilizers, there is a lack of equipment capable of real-time, precise location, and precise fertilizer application based on soil testing and fertilizer formulation, or automatic control equipment. Seeds do not completely fall from the seed tray, and some seeds get stuck in the seed holes. There is a lack of specialized tools for spot sowing, especially for handling simultaneous spot sowing on multiple rows; currently, there is no directly effective corresponding equipment.

Detailed Implementation

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model, all of which fall within the protection scope of this utility model.

[0030] Specific implementation method one: Combining Figures 1 to 7 As shown, in this embodiment, the multi-grain pile-type seeding mechanism in the ditch includes a single-outlet seeding tray 1, a seed conveying and distributing pipe 2, and multiple pile-type seeding units 3. The single-outlet seeding tray 1 is horizontally arranged, and the seed conveying and distributing pipe 2 is located below the single-outlet seeding tray 1. The seed conveying and distributing pipe 2 includes multiple conveying pipes 2-1, which are arranged between the single-outlet seeding tray 1 and the multiple pile-type seeding units 3. The upper end of each conveying pipe 2-1 is connected to the outlet 10 of the single-outlet seeding tray 1, and each conveying pipe 2-1 is correspondingly provided with one pile-type seeding unit 3. The lower end of each conveying pipe 2-1 is connected to its corresponding pile-type seeding unit 3. The specific number of conveying pipes 2-1 in the seed conveying and distributing pipe 2 corresponds to the number of pile-type seeding units 3, and they are matched one-to-one. The distance between adjacent pile-type seeding units 3 is at least 35 cm, which is conducive to the relevant sowing requirements of composite dense pile seeding.

[0031] Each seed collection unit 3 is a longitudinally arranged seed conveying structure. It can be used independently or in conjunction with other seeding components to achieve simultaneous seeding in multiple furrows. The number of seed collection units 3 needs to be increased. Each unit includes a terminal storage tank 3-1, a fixed support 3-2, a connecting sleeve 3-3, a lifting adjustment column 3-4, and an enclosing shell 3-5. The lifting adjustment column 3-4 is vertically positioned, and the connecting sleeve 3-3 is fitted onto it. The outer wall of the connecting sleeve 3-3 is fixedly connected to the fixed support 3-2. The lifting adjustment column 3-4 moves back and forth along the length of the connecting sleeve 3-3. The bottom end of the lifting adjustment column 3-4 is equipped with the enclosing shell 3-5. -5 includes two concave arc-shaped plates 3-5-1, with their front ends pressed together to form a convex tip 4. A strip-shaped notch 5 is formed between the upper sides of the enclosure shell 3-5. A lifting adjustment column 3-4 is fixedly connected to one end of the strip-shaped notch 5. The lower end of the terminal storage tank 3-1 is positioned between the strip-shaped notches 5. A wide seed-stacking opening 6 is formed on the lower side of the two concave arc-shaped plates 3-5-1. A rear opening 7 is formed between the rear ends of the two concave arc-shaped plates 3-5-1, and the rear opening 7 is connected to both the strip-shaped notch 5 and the wide seed-stacking opening 6. The inner walls of the two concave arc-shaped plates 3-5-1 form a seed-stacking cavity 8 that matches the terminal storage tank 3-1. The seed-stacking cavity 8 provides a standardized space for dense seed stacking and provides accurate seed-stacking positions for different quantities of dense seed stacking.

[0032] In this embodiment, the fixed support 3-2 provides a position for the seed collection unit 3 to connect with other components, facilitating the positioning and standardized assembly of the seed collection unit 3. The connecting sleeve 3-3 provides an installation position for the lifting adjustment column 3-4. The lifting adjustment column 3-4 moves up and down within the connecting sleeve 3-3. The movement of the lifting adjustment column 3-4 drives the enclosing shell 3-5 to move up and down synchronously. When the enclosing shell 3-5 is at the predetermined position at the lower end of the adapter terminal storage tank 3-1, the connecting sleeve 3-3 is provided with multiple tightening screws along its radial direction to fix the position of the lifting adjustment column 3-4. When a secondary adjustment of the position of the lifting adjustment column 3-4 is required, it is only necessary to loosen each tightening screw to achieve the subsequent adjustment.

[0033] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. In this implementation method, the multiple conveying pipes 2-1 are side-weighted conveying structures. The biased position of the multiple conveying pipes 2-1 is directly below the outlet 10 of the single-outlet seed dropping tray 1. The multiple conveying pipes 2-1 include a straight pipe body 2-1-1, a first inclined pipe body 2-1-3, multiple second inclined pipe bodies 2-1-4, and multiple folded pipe bodies 2-1-2. The upper end of the straight pipe body 2-1-1 is connected to the outlet of the single-outlet seed dropping tray 1 through the first inclined pipe body 2-1-3. The lower end of pipe 2-1-1 is connected to the upper end of the terminal storage tank 3-1 of a seed collection unit 3 directly below it. Multiple second inclined pipes 2-1-4 and multiple folded pipes 2-1-2 are arranged in a one-to-one correspondence. The upper end of each second inclined pipe 2-1-4 is connected to the outlet 10 of the single-outlet seed collection tray 1, and the lower end of each second inclined pipe 2-1-4 is connected to the upper end of its corresponding folded pipe 2-1-2. The lower end of each folded pipe 2-1-2 is connected to the upper end of its corresponding terminal storage tank 3-1 of the seed collection unit 3. The structural configuration of the straight pipe 2-1-1, the first inclined pipe 2-1-3, the multiple second inclined pipes 2-1-4, and the multiple folded pipes 2-1-2 in the multiple conveying pipes 2-1 facilitates the provision of multi-channel evenly distributed seeding and piling effects for the single-position outlet 10, achieving the arrangement effect of seeding and piling at multiple positions.

[0034] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. In this implementation method, the terminal storage tank 3-1 is a double-cone hard tank, that is, the terminal storage tank 3-1 has a narrow mouth at the top and bottom and a relatively long inner diameter in the middle, similar to an oval shape, which can provide favorable storage conditions for seed collection and stacking.

[0035] Furthermore, the terminal storage tank 3-1 can also be a double-cone soft capsule, and can also realize the centralized seeding process of the terminal storage tank 3-1 under external pressure during small-scale planting.

[0036] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One. In this implementation method, the lower end of the terminal storage tank 3-1 is fitted tightly or loosely with the two concave arc-shaped plates 3-5-1. When the lower end of the terminal storage tank 3-1 is fitted tightly with the two concave arc-shaped plates 3-5-1, the corresponding structural form is that the straight pipe 2-1-1 and the folded pipe 2-1-2 among the multiple conveying pipes 2-1 are corrugated pipes, thereby realizing the adjustable extension and retraction performance of the conveying pipe 2-1, so that the terminal storage tank 3-1 can be raised and lowered synchronously with the lifting adjustment column 3-4, which is conducive to adjusting to the height required for sowing.

[0037] Another corresponding structural form is that the first inclined tube 2-1-3 and the second inclined tube 2-1-4 are corrugated pipes. The effect achieved is the same as that achieved by the straight tube 2-1-1 and the folded tube 2-1-2 being corrugated pipes. Both are to enable the terminal storage tank 3-1 to move up and down synchronously with the lifting adjustment column 3-4, which is conducive to adjusting to the height required for sowing.

[0038] In this embodiment, when the lower end of the terminal storage tank 3-1 is fitted with the two concave arc-shaped plates 3-5-1 with a gap, the lifting and lowering movements of the terminal storage tank 3-1 and the lifting adjustment column 3-4 are not coordinated. By adjusting the position of the lifting adjustment column 3-4, the process of achieving different relative vertical positions between it and the terminal storage tank 3-1 can be achieved, thereby adapting to the sowing requirements of different seed burial depths and pile sizes.

[0039] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3, or 4. In this implementation method, the single-outlet seed-dropping tray 1 includes a circular base plate 1-1, an outer cylinder 1-2, a seed-dropping top plate 1-3, a seed-equalizing component, a point-to-point seed-pressing roller 1-5, and an annular fixed base plate 1-6.

The seed-dropping top plate 1-3 includes an upper annular plate 1-3-1, a cross-shaped connecting plate 1-3-2, and a centrally located conical cover 1-3-3. The upper annular plate 1-3-1 is coaxially arranged on the annular fixed base plate 1-6, and the cross-shaped connecting plate 1-3-2 is hinged to the annular fixed base plate 1-6. A cross-shaped connecting plate 1-3-2 is installed in the central hole of the upper annular plate 1-3-1.

The bottom of the seed leveling component is in clearance fit with the top surface of the upper annular plate 1-3-1. The point-to-point seed pressing roller 1-5 is hinged to the inner wall of the outer cylinder 1-2.

Each ring of protrusions is provided with a ring of multiple rings of seed receiving holes 1-7. The multiple rings of protrusions and the multiple rings of seed receiving holes 1-7 are inserted and fitted one-to-one.

[0040] In this embodiment, the top of the outer cylinder 1-2 is detachably connected to a top cover 1-9, which is used to cover the top of the single-outlet seed tray 1, thus facilitating the formation of a relatively closed uniform seeding structure.

[0041] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. The uniform thickness component in this implementation method includes an upper arc-shaped plate 1-4-1, two vertical support rods 1-4-2, and multiple uniform thickness plates 1-4-3. The two vertical support rods 1-4-2 are arranged on the inner wall of the outer cylinder 1-2 along the circumferential direction. An upper arc-shaped plate 1-4-1 is provided between the two vertical support rods 1-4-2. Multiple uniform thickness plates 1-4-3 are vertically provided on the bottom surface of the upper arc-shaped plate 1-4-1. The upper end of each uniform thickness plate 1-4-3 is fixedly connected to the upper arc-shaped plate 1-4-1, and the lower end of each uniform thickness plate 1-4-3 is spaced apart from the top surface of the upper annular plate 1-3-1.

[0042] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. In this implementation method, the point-to-point seed pressing roller 1-5 is equipped with a first connecting rod 11, a second connecting rod 12, and a fixing frame. The point-to-point seed pressing roller 1-5 includes a fixed shaft 1-5-1 and multiple connecting rollers 1-5-2. The multiple connecting rollers 1-5-2 are mounted on the fixed shaft 1-5-1 along the length direction of the fixed shaft 1-5-1. Each connecting roller 1-5-2 is hinged to the fixed shaft 1-5-1.

[0043] Furthermore, each conveying pipe 2-1 has a corresponding connecting plate 17 at its upper end. The connecting plate 17 has a connecting hole machined in the middle along its thickness direction. The connecting plate 17 is fixedly mounted on its corresponding conveying pipe 2-1 through the connecting hole. The two ends of the connecting plate 17 are detachably connected to the bottom of the single-outlet seed tray 1 to help fix the arrangement position of the conveying pipe 2-1.

[0044] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Method Seven. In this implementation method, the outlet 10 includes at least three arc-shaped elongated holes. The at least three arc-shaped elongated holes are located directly below the point-to-point seed pressing roller 1-5. The length of the at least three arc-shaped elongated holes decreases sequentially from the outside to the inside along the circumferential direction of the annular fixed base plate 1-6. A ring of seed-receiving holes 1-7 is correspondingly provided above each arc-shaped elongated hole. Each arc-shaped elongated hole is connected to its corresponding ring of seed-receiving holes 1-7. A conveying pipe 2-1 is correspondingly provided below each arc-shaped elongated hole. The upper end of each arc-shaped elongated hole is connected to its corresponding conveying pipe 2-1.

[0045] In this embodiment, the usage process of the single-outlet seed tray 1 is as follows:

[0046] A predetermined amount of seeds is placed in the outer cylinder 1-2 and placed on the seed dropping plate 1-3. The motor is started, and the motor drives the seed dropping plate 1-3 to rotate. The seeds are evenly spread between the stationary seed distribution component and the rotating top surface of the seed dropping plate 1-3. The seeds enter the multi-ring seed receiving holes 1-7 and are squeezed through the seed receiving holes 1-7 below the point-to-point pressing roller 1-5, and enter each conveying pipe 2-1 through the outlet 10.
