[0002] At present, crops in my country are mainly sown, but with the development of agricultural technology, many advantages of seedling transplanting are becoming increasingly apparent. The advantages of seedling transplanting are not only reflected in saving seeds, improving seedling rate, saving maintenance costs and resources, but also in seedling selection, root cutting and rejuvenation, and transplant survival rate. At the same time, due to the low efficiency of artificial pot seedling transplanting and the continuous increase in labor costs, high-efficiency and low-cost agricultural machinery transplanters for pot seedling transplanting are increasingly widely used in agricultural production. There are many types of transplanters, which can be divided into hanging basket duckbill transplanting mechanisms, eccentric wheel duckbill transplanting mechanisms, crank-connecting rod duckbill transplanting mechanisms, and multi-link duckbill transplanting mechanisms according to their movement mechanisms.

[0003] However, the existing duckbill transplanting mechanism has the following problems: the structure of driving the duckbill to open and close is complex, the manufacturing difficulty is relatively large, the motion trajectory is complex and difficult to control, and the service life is short. In addition, it has high requirements for the working environment, is easy to damage, difficult to repair, and has high manufacturing costs. For example, when the hanging basket duckbill transplanter is operating, its forward speed and transplanting speed have high requirements, and the transplanting operation is relatively complicated. Therefore, it is urgent to develop a new type of duckbill transplanting mechanism with a simpler structure, easy to process, and able to meet different operating requirements.

DETAILED DESCRIPTION

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0041] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] This embodiment relates to a novel duckbill transplanting mechanism, an exemplary structure of which is as follows: Figure 1 and Figure 2As shown, the novel duckbill transplanting mechanism mainly includes a mounting frame and a transplanter assembly arranged on the mounting frame, wherein a rotating member is pivotally provided on the mounting frame, and an opening and closing adjustment wheel 81 with a cross section of an equilateral triangle is mounted on the rotating member, and the transplanter assembly includes a seedling guide bucket 2 and a support frame 4 fixedly connected to the mounting frame, and a guide rail bracket 3 is provided between the seedling guide bucket 2 and the support frame 4 and abuts against the opening and closing adjustment wheel 81, and a duckbill opening and closing piece assembly 10 that can be opened and closed is connected to the guide rail bracket 3, and the duckbill opening and closing piece assembly 10 can be opened and closed. 0 comprises two duckbill opening and closing pieces hinged to each other at the ends, and elastic reset members 6 are provided on the two duckbill opening and closing pieces, and the elastic reset members 6 are limitedly moved on the support frame 4, and due to the rotation of the opening and closing adjustment wheel 81, the guide rail bracket 3 can move downward to open the duckbill opening and closing pieces; the elastic reset member 6 has an elastic force applied to the duckbill opening and closing pieces due to the downward movement of the guide rail bracket 3, and as the opening and closing adjustment wheel 81 continues to rotate, the guide rail bracket 3 moves upward due to the elastic force, so that the duckbill opening and closing is closed, thereby realizing the transplanting operation.

[0044] In terms of specific structure, Figure 1 Combination Figures 2 to 4 As shown, the mounting frame of this embodiment is two mounting side plates 1 arranged at a distance, and the aforementioned seedling guide bucket 2 and support frame 4 are fixedly connected to the mounting side plates 1 by connecting members such as bolts and nuts that are screwed to the fixing holes 24. Of course, the mounting frame can also be other structural forms, such as adding a connecting plate between the two mounting side plates 1, or other frame structures, so as to provide a connection basis for the seedling guide bucket 2 and the support frame 4 and the driving bracket 11 described below.

[0045] The aforementioned rotating member is two driven shafts 8 in this embodiment that are respectively pivotally mounted on the two mounting side plates 1 and arranged coaxially. Of course, it can also be one driven shaft 8 that is pivotally mounted on the two mounting side plates 1, but the arrangement position and number of the driven shafts 8 need to be improved accordingly. This structural form is not described in detail here. In order to facilitate the placement of the plants to be transplanted in the seedling guide bucket 2, two driven shafts 8 are preferably used in this embodiment, and in order to facilitate the stability of the driven shaft 8, combined with Figures 4 to 7 As shown, a rotating shaft mounting hole 25 is provided on the seedling guide bucket 2 for the driven shaft 8 to pass through.

[0046] As a preferred embodiment, Figure 4 and Figure 5As shown, the cross section of the opening and closing adjustment wheel 81 of this embodiment is an equilateral triangle, and has an arc-shaped push end, and a straight end tangent to and connected to the push end. When the rotating member, that is, the driven shaft 8, rotates, the push end and the straight end sequentially abut against the upper surface of the guide rail bracket 3, so that the guide rail bracket 3 can move downward. Of course, the cross-sectional shape of the opening and closing adjustment wheel 81 can also be a square, a regular pentagon or a regular hexagon, etc., but compared with the regular triangle, the structure of the opening and closing adjustment wheel 81 in the shape of an equilateral triangle is not as good as that of the opening and closing adjustment wheel 81 in the shape of an equilateral triangle in ensuring the opening and closing angle of the duckbill opening and closing piece, the opening and closing cycle and frequency have a better use effect. In addition, in the structure using a square or regular pentagon or regular hexagon, the size of the parts needs to be set larger.

[0047] See also Figures 1 to 3 As shown, a Z-shaped driving bracket 11 is fixedly connected to both sides of the mounting frame, that is, the mounting side plate 1, and the driving bracket 11 is pivotally connected to an external component such as a tractor frame through a fixed shaft 100, and a transmission mechanism for rotating the driving bracket 11 is pivotally provided on the external component. It should be noted that the driving bracket 11 and the mounting side plate 1 can be fixedly connected together by screwing or welding, and can also be an integrally formed structure.

[0048] In this embodiment, a driven sprocket 82 is mounted on the rotating member, that is, the driven shaft 8, and the transmission mechanism includes a driving shaft 7 pivotally arranged on an external component, two driving sprockets 72 symmetrically mounted on both ends of the driving shaft 7, and a chain (not shown in the figure) wound around the driving sprocket 72 and the driven sprocket 82. Two depth adjustment wheels 71 are symmetrically mounted on the driving shaft 7 between the two driving sprockets 72, and the two depth adjustment wheels 71 abut against the upper surface of the driving bracket 11, so that the rotation of the driving shaft 7 drives the rotation of the depth adjustment wheel 71, so that the driving bracket 11 rotates around the fixed axis 100, and then the duckbill opening and closing piece assembly 10 can reciprocate up and down, so as to cooperate with the opening and closing of the duckbill opening and closing piece to complete the transplanting work.

[0049] As a preferred embodiment of the present embodiment, the cross-section of the depth adjustment wheel 71 of the present embodiment is triangular, and the depth adjustment wheel 71 has an arc-shaped pushing end, and a straight end tangent to and connected to the pushing end. Under the rotation of the driving shaft 7, the pushing end and the straight end sequentially abut against the upper surface of the driving bracket 11, thereby causing the driving bracket 11 to reciprocate along the height direction.

[0050] like Figure 6 and Figure 7As shown, the seedling guide bucket 2 of this embodiment has a connecting and mounting section 22 fixedly connected to the mounting frame, a cylindrical section 21 located at the upper end of the connecting and mounting section 22 and a conical section 23 located below the connecting and mounting section 22, wherein the connecting and mounting section 22 is a rectangular shell, and fixing holes 24 that can be connected to the mounting side plate 1 and a rotating shaft mounting hole 25 for the driven shaft 8 to pass through are constructed on the opposite side surfaces of the connecting and mounting section 22. In addition, the connecting and mounting section 22 and the conical section 23 are placed in the guide rail bracket 3, and the guide rail bracket 3 is slidably arranged on the support frame 4, so as to facilitate the sliding arrangement of the guide rail bracket 3 on the support frame 4.

[0051] Specifically, by Figure 4 , Figure 5 Combination Figure 8 , Fig. 9 As shown, a guide rail 31 is constructed on the guide rail bracket 3, wherein the guide rail bracket 3 has a structure adapted to connect the mounting section 22, that is, it has a rectangular shell, and the guide rails 31 are arranged in a spaced manner as thin strips, and the guide rails 31 are arranged on two opposite sides. Corresponding to each guide rail 31, a slide groove 41 is arranged on the support frame 4, and the cross-sectional shape of the slide groove 41 is T-shaped, so that the guide rail 31 can be limited to slide in the slide groove 41, and the guide rail 31 can slide up and down along the slide groove 41 to constitute the guide rail bracket 3 relative to the support frame 4. Up and down sliding of the guide rail 31 can constitute the up and down reciprocating movement of the guide rail bracket 3 relative to the support frame 4.

[0052] See also Figures 4 to 10 As shown, a fixed link 32 is provided on the guide rail bracket 3, and two adjusting rods 5 are hinged on the fixed link 32. Relative to one end hinged to the fixed link 32, the other ends of the two adjusting rods 5 are respectively hinged to the two duckbill opening and closing pieces. Specifically, the guide rail bracket 3 is provided with a fixed link 32 on two side surfaces of the guide rail 31, and the fixed link 32 is located between the two guide rails 31 on the same side, so that after the adjusting rod 5 is connected, the thrust applied to the duckbill opening and closing piece can be more stable. In addition, an inclined supporting surface 33 is formed at the top of the fixed link 32, so as to smoothly abut against the conical section 23 of the seedling guide bucket 2, and at the same time play a certain supporting role on the conical section 23.

[0053] like Fig.10 As shown, the duckbill opening and closing piece assembly 10 of this embodiment includes two duckbill opening and closing pieces hinged at the ends, that is, Fig.10The first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102 are shown in the figure. The first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102 are symmetrically semi-conical, that is, they are conical when they are in the locked state. The first pivot seat 1013 and the second pivot seat 1023 are respectively formed at the top of the first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102. The first pivot seat 1013 and the second pivot seat 1023 are hinged by the installed pivot shaft 20, such as bolts or pins. By setting the fixed connecting rod 32 on the guide rail bracket 3 and the adjusting rod 5 hinged to the fixed connecting rod 32, when the guide rail bracket 3 moves, it is conducive to the duckbill opening and closing piece to open and close with the movement of the guide rail bracket 3. The structure has a simple structure, is easy to manufacture and process, and has a good synchronization effect of movement.

[0054] In addition, a first adjustment rod mounting column 1012 and a second adjustment rod mounting column 1022 are respectively provided on the first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102, so that the above-mentioned adjustment rod 5 is respectively hingedly connected with the first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102. In addition, a first positioning column 1011 and a second positioning column 1021 are respectively formed on the two duckbill opening and closing pieces, that is, on the first duckbill opening and closing piece 101 and the second duckbill opening and closing piece 102, and the first positioning column 1011 and the second positioning column 1021 are inserted into the opening and closing sliding groove 42 formed on the support frame 4, and can synchronously slide in the opposite direction along the opening and closing sliding groove 42 due to the opening and closing of the two duckbill opening and closing pieces. Among them, the opening and closing sliding groove 42 is in the shape of a long strip, and the long axis direction of the opening and closing sliding groove 42 is set along the opening and closing direction of the two duckbill opening and closing pieces, so as to facilitate the first positioning column 1011 and the second positioning column 1021 to slide in the opening and closing sliding groove 42 so that the two duckbill opening and closing pieces can be opened and closed smoothly.

[0055] In this embodiment, the two ends of the elastic reset member 6 are respectively fixedly connected to the first positioning column 1011 and the second positioning column 1021, so that the duckbill opening and closing piece can be quickly closed under the elastic force of the elastic reset member 6. By providing the first positioning column 1011 and the second positioning column 1021, it is convenient to position the duckbill opening and closing piece assembly 10 on the one hand, and to install the elastic reset member 6 on the other hand. The elastic reset member 6 of this embodiment is preferably a spring.

[0056] A new type of duckbill transplanting mechanism of this embodiment can be used for transplanting various vegetables such as peppers, stevia, etc., and is particularly suitable for transplanting stevia. Of course, other crops or plants can also be transplanted. Its use process is as follows: at the beginning of the transplanting operation, the plane where the straight end of the opening and closing adjustment wheel 81 is located abuts against the upper surface of the guide rail bracket 3, and the duckbill is a closed device. During the transplanting operation, when the opening and closing adjustment wheel 81 rotates to the arc-shaped push end abuts against the upper surface of the guide rail bracket 3, the guide rail 31 on the guide rail bracket 3 moves downward along the slide groove 41. Since the duckbill opening and closing piece is limited on the support frame 4 by the first positioning column 1011 and the second positioning column 1021, during the downward movement of the guide rail bracket 3, the adjustment rod 5 opens and drives the first positioning column 1011 and the second positioning column 1021 to move away synchronously in the opposite direction along the opening and closing sliding groove 42, so that the duckbill opens. When the opening and closing adjustment wheel 81 continues to rotate, so that the plane where the straight end is located abuts against the upper surface of the guide rail bracket 3 again, under the elastic force of the spring, the first positioning column 1011 and the second positioning column 1021 synchronously approach each other in opposite directions along the opening and closing sliding groove 42, and the guide rail bracket 3 moves upward, so that the duckbill closes.

[0057] Among them, it should be noted that the opening and closing adjustment wheel 81 rotates one circle, and the duckbill opening and closing piece completes three closing movements. It should also be noted that the shape of the depth adjustment wheel 71 of this embodiment matches the shape of the opening and closing adjustment wheel 81. The depth adjustment wheel 71 is driven to rotate by a driving device on an external component, such as an engine. During the rotation process, when the arc-shaped pushing end abuts against the upper surface of the driving bracket 11, it can drive the mounting side plate 1 to rotate around the fixed axis 100 and insert the duckbill opening and closing piece into the soil. At this time, the arc-shaped pushing end on the opening and closing adjustment wheel 81 abuts against the upper surface of the guide rail bracket 3, and the duckbill opening and closing piece is in a fully open state to complete the transplanting. Of course, an elastic reset member 6 or other reset mechanism such as a cam needs to be added to the external component to facilitate the reset of the driving bracket 11.

[0058] In addition, the transmission ratio of the driving sprocket 72 and the driven sprocket 82 of this embodiment is preferably 1:1, so as to ensure that the rotation angles of the depth adjustment wheel 71 and the opening and closing adjustment wheel 81 are consistent. At the same time, the shape of the depth adjustment wheel 71 is matched with the shape of the opening and closing adjustment wheel 81 to improve the synchronization of movement, so that when the duckbill opening and closing piece assembly 10 is inserted into the soil at the deepest, the duckbill opening and closing piece can be fully opened, thereby facilitating transplanting. In addition, a new type of duckbill transplanting mechanism of this embodiment can also adjust the transplanting spacing according to the driving speed of the external component and the rotation speed of the driving shaft.

[0059] A novel duckbill transplanting mechanism of the present embodiment drives the guide rail bracket 3 to move downward by rotating an opening and closing adjusting wheel 81 having a regular triangle cross section, and drives the duckbill opening and closing piece to open. In addition, an elastic reset member 6 is arranged on the duckbill opening and closing piece to accumulate elastic force after the duckbill opening and closing piece is opened, so that when the opening and closing adjusting wheel 81 continues to rotate, the elastic force acts on the duckbill opening and closing piece to close, and pushes the guide rail bracket 3 to move upward. Compared with the prior art, this novel duckbill transplanting mechanism has a simpler principle, a clear and traceable motion trajectory, and a simpler structure, which is easy to process and manufacture. At the same time, it has strong adaptability and can meet different operation requirements, thereby having a better use effect.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
