Description

Technical Field

[0001] The present invention belongs to the field of crop planting, and particularly relates to a seedling soil covering and pressing mechanism. Background Art

[0002] Currently, after an agricultural transplanter pre-inserts a batch of seedlings at uniform intervals into the planting ground, due to hardware reasons of the transplanting mechanism, the pre-insertion depth of the seedlings is relatively shallow, and the seedlings are very likely not perpendicular to the ground surface. Therefore, under the influence of external environmental factors or the gravity of the center of gravity of the seedlings themselves, it may lead to lodging within a short time after the seedlings are pre-inserted into the planting ground, thus affecting the success rate of transplantation.

[0003] To solve the above problems, a soil cultivation mechanism is provided on the agricultural transplanter, that is, after the seedlings are pre-inserted into the planting ground, the soil cultivation mechanism forms a continuous ridge body slightly higher than the original planting ground by squeezing the predetermined planting ground on the predetermined planting ground, and multiple seedlings are located on the ridge body. Since the ridge body is formed by extrusion, the depth of the seedlings inserted into the predetermined planting ground is further increased compared to the pre-insertion depth, thereby serving as a means to cope with the lodging phenomenon. The existing soil cultivation mechanism realizes soil cultivation by simultaneously squeezing with a pair of oppositely inclined pressing wheels.

[0004] However, the above implementation has deficiencies: since the outer surface of the pressing wheel is arc-shaped, the cutting force applied to the basically horizontal planting ground is relatively small, and not much soil surface layer can be cut to form a ridge body. Therefore, the ridge body is only slightly higher than the original planting ground, that is, the depth of the seedlings inserted into the predetermined planting ground is not increased much compared to the pre-insertion depth. Moreover, this method cannot solve the non-perpendicular problem between the seedlings and the ground surface, so the effect of preventing lodging is relatively limited. In addition, since the pressing wheel maintains pressure extrusion with the planting ground throughout the process, the wear of the pressing wheel is also relatively large. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a seedling soil covering and pressing mechanism, which can cut more soil surface layer to form a ridge body. Therefore, the ridge body is much higher than the original planting ground, that is, the depth of the seedlings inserted into the predetermined planting ground is increased more compared to the pre-insertion depth. Moreover, the corresponding executing part does not need to maintain the force on the planting ground throughout the process, so the wear of the executing part is also greatly reduced.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A seedling soil covering and pressing mechanism, where seedlings are pre-inserted into a predetermined planting ground and multiple seedlings are arranged at intervals along a predetermined planting line. The characteristics are as follows: a connecting frame, which is connected to a predetermined agricultural machinery that travels on the predetermined planting ground; a pair of soil scooping components, which are arranged on the connecting frame and are symmetrically arranged with respect to the vertical plane where the predetermined planting line is located. The soil scooping component includes a soil scooping actuator that can move in a predetermined direction, the predetermined direction is perpendicular to the predetermined planting line and is inclined towards the predetermined planting ground. Among them, the soil scooping actuator includes a soil scooping semi-cylinder. The orthographic projection of the pair of soil scooping semi-cylinders on the predetermined planting ground is a semi-circular ring that is symmetric and facing each other with respect to the vertical plane where the predetermined planting line is located. The soil scooping semi-cylinder has a continuously bent soil covering arc surface and a soil pressing arc surface in the vertical direction. The soil pressing arc surface is closer to the predetermined planting ground than the soil covering arc surface, and the soil pressing arc surface is bent away from the predetermined planting line based on the soil covering arc surface. When the pair of soil scooping actuators move towards each other from opposite sides towards the predetermined planting line and the pair of soil scooping semi-cylinders move to contact the predetermined planting ground, the pair of soil pressing arc surfaces push the surface layer of the predetermined planting ground towards the seedlings to form a pushed surface layer. The pair of soil pressing arc surfaces press a part of the pushed surface layer, and the rest continues to be pushed along the soil pressing arc surface towards the pair of soil covering arc surfaces. Thus, the pair of soil covering arc surfaces push the rest and cover the roots of the seedlings with soil.

[0008] Preferably, the soil scooping actuator further includes an actuator base, the actuator base is semi-cylindrical, and is sleeved outside the soil scooping semi-cylinder. There is a step difference in the vertical direction between the bottom of the inner surface of the actuator base and the bottom of the soil scooping semi-cylinder, and the bottom of the actuator base is closer to the predetermined planting ground than the bottom of the soil scooping semi-cylinder. When the pair of soil scooping actuators move towards each other from opposite sides towards the predetermined planting line and the pair of soil scooping semi-cylinders move to contact the predetermined planting ground, the step difference arc surface and the soil pressing arc surface formed by the actuator base relative to the soil scooping semi-cylinder both apply pressure to the pushed surface layer.

[0009] Furthermore, the bottom of the actuator base is formed with a soil shoveling slope surface extending towards the predetermined planting ground, and the soil shoveling slope surface is continuous with the inner surface of the actuator base and forms an acute-angle bend.

[0010] Preferably, the pair of soil pressing arc surfaces are located on the same conical surface, and the pair of soil covering arc surfaces are located on the same cylindrical surface.

[0011] Preferably, the pair of soil pressing arc surfaces and the pair of soil covering arc surfaces are respectively located on two different conical surfaces.

[0012] Preferably, the soil scooping component further includes an electric push rod, and the connecting frame is coupled to the soil scooping actuator through the electric push rod.

[0013] Further, the seedling soil covering mechanism is arranged on a predetermined agricultural machine through a connecting frame. The predetermined agricultural machine is provided with a seedling dropping device. The seedling dropping device inserts seedlings into the predetermined planting ground in advance through an energized seedling dropping prime mover. The starting circuit of the electric push rod and the starting circuit of the seedling dropping prime mover are connected in parallel to form an energized circuit.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. Since the seedling soil covering and pressing mechanism of the present invention includes a connecting frame and a pair of soil scooping components, the pair of soil scooping components are symmetrically arranged with respect to the vertical plane where the predetermined planting line is located. The soil scooping component includes a soil scooping actuator that can move in a predetermined direction. The predetermined direction is perpendicular to the predetermined planting line and is inclined towards the predetermined planting ground. The soil scooping actuator includes a soil scooping semi-cylinder. The soil scooping semi-cylinder has a continuously bent soil covering arc surface and a soil pressing arc surface in the vertical direction. The soil pressing arc surface is closer to the predetermined planting ground than the soil covering arc surface. When the pair of soil scooping actuators move towards each other, and the pair of soil scooping semi-cylinders move to contact the predetermined planting ground, the pair of soil pressing arc surfaces push the surface layer of the predetermined planting ground towards the seedlings to form a pushed surface layer. The pair of soil pressing arc surfaces compact a part of the pushed surface layer, and the remaining part continues to be pushed along the soil pressing arc surface towards the pair of soil covering arc surfaces. Thus, the pair of soil covering arc surfaces push and cover the remaining part around the roots of the seedlings. That is, the soil scooping actuator is inclined to insert into the predetermined planting ground, thereby forming more pushed surface layers, and the soil scooping actuator can be far away from or inserted into the predetermined planting ground, so that it does not form a force action with the predetermined planting ground throughout the process. Therefore, the present invention can shovel and cut more land surface layers to form ridges, so that the ridges are much higher than the original planting ground, which means that the depth of the seedlings inserted into the predetermined planting ground increases more than the pre-insertion depth. Moreover, the corresponding actuator does not need to maintain a force action on the planting ground throughout the process, so the wear of the actuator is greatly reduced.

[0016] 2. Since the soil scooping actuator of the present invention further includes an actuator base, the actuator base is sleeved outside the soil scooping semi-cylinder in a matching manner. There is a step difference in the vertical direction between the bottom of the inner surface of the actuator base and the bottom of the soil scooping semi-cylinder, and the bottom of the actuator base is closer to the predetermined planting ground than the bottom of the soil scooping semi-cylinder. When the pair of soil scooping actuators move towards each other from opposite sides towards the predetermined planting line, and the pair of soil scooping semi-cylinders move to contact the predetermined planting ground, the step difference arc surface and the soil pressing arc surface formed by the actuator base relative to the soil scooping semi-cylinder both apply pressure to the pushed surface layer. Therefore, the present invention makes the pushed surface layer be squeezed more tightly under the vector pressure of the two surfaces through the step difference arc surface and the soil pressing arc surface.

[0017] 3. Since the bottom of the actuator base of the present invention is formed with a soil shoveling slope surface extending towards the predetermined planting ground, and the soil shoveling slope surface is continuous with the inner surface of the actuator base and forms an acute-angle bend, that is, the soil shoveling slope surface forms an acute-angle bend towards the ground at the bottom of the actuator base, which is equivalent to a shovel cutting edge. Therefore, the actuator base of the present invention is more likely to form a deeper shovel cutting depth on the predetermined planting ground, thereby forming a thicker pushed surface layer.

[0018] 4. Since the pair of soil pressing arc surfaces and the pair of soil covering arc surfaces of the present invention are respectively located on two different conical surfaces, the soil covering of the pair of soil covering arc surfaces for the seedlings is also in a conical surface. Therefore, when the seedlings are not perpendicular to the predetermined planting ground, the seedlings can be corrected to be perpendicular to the predetermined planting ground.

[0019] 5. Since the seedling soil covering mechanism of the present invention is arranged on a predetermined agricultural machine through a connecting frame, and the predetermined agricultural machine is provided with a seedling dropping device. The seedling dropping device inserts seedlings into the predetermined planting ground in advance through an energized seedling dropping prime mover. The starting circuit of the electric push rod and the starting circuit of the seedling dropping prime mover are connected in parallel to form an energized circuit. Specifically, the predetermined agricultural machine is a seedling transplanting device. Therefore, the electric push rod of the present invention is energized synchronously with the seedling dropping device of the predetermined agricultural machine. Through the moving speed of the seedling transplanting device, it can be conveniently realized that after the seedlings are pre-inserted, then the soil covering and soil pressing are completed through the soil scooping component, that is, soil cultivation is realized. And if there is a functional failure, the seedling dropping prime mover and the electric push rod will stop synchronously, so that the phenomenon of not cultivating soil after pre-inserting seedlings or cultivating soil without pre-inserting seedlings will not occur.

Specific Embodiment

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the following embodiments will specifically describe the seedling soil covering and soil pressing mechanism of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention.

[0028] <Example 1>

[0029] In the seedling soil covering and soil pressing mechanism 100 of this embodiment, the seedlings R are pre-inserted into the predetermined planting ground G, and multiple seedlings R are arranged at intervals along the predetermined planting line. Specifically, the insertion points of multiple seedlings R into the predetermined planting ground G are all located on the predetermined planting line.

[0030] As Figure 1 and Figure 2 shown, the seedling soil covering and soil pressing mechanism 100 includes a connecting frame 10 and a soil scooping assembly 20.

[0031] The connecting frame 10 is connected to the predetermined agricultural machine S, and the predetermined agricultural machine S travels on the predetermined planting ground G. Specifically, the predetermined agricultural machine S is an agricultural transplanter. The agricultural transplanter pre-inserts the seedlings R into the predetermined planting ground G through its own seedling dropping device. The seedling soil covering and soil pressing mechanism 100 is arranged at the tail of the agricultural transplanter. Thus, after the seedlings R are pre-inserted, the agricultural transplanter continues to travel. When the seedling soil covering and soil pressing mechanism 100 is near the seedlings R, the seedling soil covering and soil pressing mechanism 100 simultaneously covers soil and presses soil for the seedlings R.

[0032] As Figure 3 and Figure 4 shown, the number of the soil scooping assemblies 20 is one pair, which is arranged on the connecting frame 10, and the one pair of soil scooping assemblies 20 are symmetrically arranged with the vertical plane where the predetermined planting line is located as the symmetry plane. In this embodiment, the number of the connecting members 10 is one pair, which are respectively arranged on the two side edges of the tail of the predetermined agricultural machine S.

[0033] The soil scooping assembly 20 includes an electric push rod 21 and a soil scooping actuator 22.

[0034] The fixed end of the electric push rod 21 is fixedly arranged on the connecting frame 10, and the telescopic end is fixedly connected to the soil scooping actuator 22. Thus, the connecting frame 10 is coupled to the soil scooping actuator 22 through the electric push rod 21, and the electric push rod 21 extends along a predetermined direction D. The predetermined direction D is perpendicular to the predetermined planting line and is inclined towards the predetermined planting ground G. Since there are a pair of soil scooping assemblies 20 and a pair of electric push rods 21, there are a pair of predetermined directions D, and the pair of predetermined directions D are inclined towards each other, and the convergence intersection point is located in the vertical plane where the predetermined planting line is located and below the predetermined planting ground G.

[0035] The seedling soil covering mechanism 100 is arranged on the predetermined agricultural machinery S through the connecting frame 10. The predetermined agricultural machinery S is provided with a seedling dropping device (not shown in the drawings). The seedling dropping device inserts the seedlings R into the predetermined planting ground G in advance through an energized seedling dropping prime mover (not shown in the drawings).

[0036] The start-up circuit of the electric push rod 21 and the start-up circuit of the seedling dropping prime mover are connected in parallel to form an energized circuit. Specifically, the electric push rod 21 and the seedling dropping prime mover are energized simultaneously and start to operate.

[0037] The soil scooping actuator 22 includes an actuator base 221 and a soil scooping semi-cylinder 222.

[0038] The actuator base 221 is semi-cylindrical. Specifically, the actuator base 221 has an open end face and a cylindrical cavity that is open at both the upper and lower ends. The open end face is parallel to the vertical plane where the predetermined planting line is located. The cylindrical cavity is semi-cylindrical and extends in the vertical direction, and the cylindrical cavity is completely open at the open end face.

[0039] A soil shoveling slope 221a extending towards the predetermined planting ground G is formed at the bottom of the actuator base 221, and the soil shoveling slope 221a is continuous with the inner surface of the actuator base 221 and forms an acute-angle bend. Specifically, the inner surface of the actuator base 221 has the inner surface of the cylindrical cavity, and the acute-angle bend forms a semi-circular cutting edge at the bottom of the actuator base 221.

[0040] The soil scooping semi-cylinder 222 is fitted and sleeved inside the actuator base 221. The orthographic projection of the pair of soil scooping semi-cylinders 222 on the predetermined planting ground G is a semi-circular ring that is symmetric and arranged towards each other with the vertical plane where the predetermined planting line is located as the symmetry plane. Specifically, the soil scooping semi-cylinder 222 has an outer peripheral surface with a semi-cylindrical surface corresponding to the cylindrical cavity of the actuator base 221, and the soil scooping semi-cylinder 222 has an inner surface in the shape of a semi-cylindrical surface.

[0041] The soil scooping semi-cylinder 222 has a soil covering arc surface 222a and a soil pressing arc surface 222b that are continuously bent in the vertical direction.

[0042] The soil pressing arc surface 222b is closer to the predetermined planting ground G than the soil covering arc surface 222a, and the soil pressing arc surface 222b is bent away from the predetermined planting line based on the soil covering arc surface 222a, that is, the lowest end of the soil pressing arc surface 222b is located on the inner surface of the actuator base 221. Specifically, the soil covering arc surface 222a is the inner surface of the soil scooping semi-cylinder 222 presenting a semi-cylindrical surface.

[0043] A pair of soil pressing arc surfaces 222b are located on the same conical surface, and a pair of soil covering arc surfaces 222a are located on the same cylindrical surface.

[0044] There is a step difference in the vertical direction between the bottom of the inner side surface of the actuator base 221 and the bottom of the soil scooping semi-cylinder 222, and the bottom of the actuator base 221 is closer to the predetermined planting ground G than the bottom of the soil scooping semi-cylinder 222. Specifically, the bottom of the inner side surface of the actuator base 221 is the semi-circular cutting edge at the bottom of the actuator base 221, and the bottom of the inner side surface of the actuator base 221 is the lowest end of the soil pressing arc surface 222b. This step difference forms a step difference arc surface 222A presenting a cylindrical surface on the inner surface of the actuator base 221.

[0045] When a pair of soil scooping actuators 22 move towards each other from opposite sides towards the predetermined planting line, and a pair of soil scooping semi-cylinders 222 move to contact the predetermined planting ground G, the cutting edge at the bottom of the actuator base 221 cuts into the predetermined planting ground G. At the same time, the actuator base 221 continues to move along the predetermined direction D, so that the cutting edge scrapes off and drives a part of the surface layer of the predetermined planting ground G. This moving part of the surface layer is used as the pushed surface layer M. The step difference arc surface 222A and the soil pressing arc surface 222b formed by the actuator base 21 relative to the soil scooping semi-cylinder 222 both apply pressure to the pushed surface layer M.

[0046] Thus, a pair of soil pressing arc surfaces 222b push the pushed surface layer M towards the seedling R. A part of the pushed surface layer M is pressured by a pair of step difference arc surfaces 222A and soil pressing arc surfaces 222b, so that this part of the pushed surface layer M surrounds and compresses the root of the seedling R; the remaining part continues to be pushed along the surface of the soil pressing arc surface 222b towards a pair of soil covering arc surfaces 222a. Thus, a pair of soil covering arc surfaces 222a push the remaining part, and finally, the remaining part of the pushed surface layer M forms soil covering around the root of the seedling R.

[0047] In this embodiment, the seedling dropping prime mover is a vertically driven electric cylinder. After the seedling dropping prime mover is powered on, the seedling dropping device starts the pre-insertion action of the seedling R. At the same time, the seedling soil covering mechanism 100 performs soil pressing and soil covering on the previously pre-inserted seedling R that is immediately adjacent to the position where the current seedling R is inserted. If the current is the first seedling R on the predetermined planting line, the seedling soil covering mechanism 100 has no corresponding seedling R and performs an empty action once; if the current is the last seedling R on the predetermined planting line, the seedling dropping prime mover has no corresponding seedling R and performs an empty action once.

[0048] <Example 2>

[0049] In the second embodiment, the same symbols are given to the same structures as in the first embodiment, and the same descriptions are omitted.

[0050] In the second embodiment, the difference between the seedling soil covering and pressing mechanism 100 and that of the first embodiment lies in:

[0051] As Figure 5 and Figure 6 shown, the open end face of the first embodiment is perpendicular to the predetermined planting ground G, while the open end face of the first embodiment is inclined with respect to the predetermined planting ground G. The upper parts of a pair of open end faces are close to each other, while the lower parts are far from each other. As a result, a pair of soil pressing arc surfaces 222b and a pair of soil covering arc surfaces 222a are respectively located on two different conical surfaces. Specifically, for a soil covering arc surface 222a, the soil covering arc surface 222a can be considered as a part of the cylindrical surface or a part of the conical surface. The difference lies in whether the open end face of the soil scooping semi-cylinder 222 is a vertical plane with respect to the predetermined planting ground G or not.

[0052] The above embodiments are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by those of ordinary skill in the art without creative labor within the scope of the appended claims still fall within the protection scope of this patent.
