Description

Technical Field

[0001] The present invention relates to the technical field of peanut planting devices, and specifically to a peanut dibbling device. Background Art

[0002] Peanut sowing refers to the process of sowing peanut seeds into the soil to promote their growth and development. Dibbling is a common planting method for peanut sowing. In the prior art, large sowing machines are often used for large-area and high-efficiency sowing. However, in some areas with complex terrains and small areas, large mechanical sowing devices may not work smoothly, while push-type sowing devices are more flexible and easier to operate on narrow or irregular plots. Therefore, lightweight push-type sowing devices still play an important role in small-scale, complex situations or specific environments.

[0003] There is a patent with the application number 202410277089.X in the prior art, which provides a hilly and mountainous peanut light, simple and precise sowing device, including a handcart, a movable planting component and a feeding component assembled on the handcart; the handcart includes a frame, moving wheels assembled at the bottom of the frame, and a handrail assembled on the frame; the movable planting component includes a punching and planting part and a rotary driving part; among them, the punching and planting part includes a horizontally moving pipe and a punching pipe sleeved slidably, and the horizontally moving pipe is arranged vertically. The present invention is small in volume and light in weight, and can keep the punching pipe stationary relative to the handcart and vertically insert into the ground for punching and planting work during the movement of the handcart.

[0004] However, the sowing device provided by the above patent still has the following deficiencies during use:

[0005] First, according to its content, the columnar sowing spacing is a fixed value, and the sowing depth is also a fixed value. In fact, different requirements exist for the spacing and sowing depth of peanut dibbling. For example, different peanut varieties may have different requirements for spacing and depth. Some high-yield or large peanut varieties require a larger spacing to ensure sufficient growth space for the plants. In deep and fertile soil, a smaller dibbling spacing can be adopted, while in poor or shallow soil, a larger spacing is required to avoid plant competition for nutrients. In loose and porous soil, the sowing can be appropriately deepened, while in heavy clay soil, an appropriate sowing depth should be maintained to ensure a good emergence rate.

[0006] II. According to its content, through the cooperative setting of the material taking wheel and the material taking groove, the quantitative feeding of peanut seeds is realized; however, when actually sowing peanuts, due to different peanut varieties, there are often size differences in their seeds. Therefore, the above sowing device is only applicable to the sowing work of specified varieties of peanuts. When the size of peanut seeds changes, the number of seeds that can be accommodated in the material taking groove is likely to change, thus reducing the quality of peanut sowing work, and its practicability needs to be improved.

[0037] Beneficial effects of the present invention:

[0038] 1. The sowing mechanism in the present invention is driven by the rotation of the rotating shaft 1. When the number of the feeding troughs is fixed and the transmission ratio of the transmission assembly is fixed, the row-wise sowing spacing of the peanuts is always a fixed value, that is, regardless of the speed of the push, the peanuts can maintain a uniform sowing state; and when the spacing needs to be adjusted, only the gear box needs to be adjusted. Therefore, the setting of the transmission connection between the rotating shaft 1 and the sowing mechanism through the transmission assembly facilitates the user to flexibly adjust the row-wise planting spacing of the peanuts within a certain range according to actual needs, and can meet the sowing requirements of different varieties of peanuts in terms of planting spacing, thereby improving the practicality of the present invention.

[0039] 2. The present invention arranges a space limiting mechanism in the feeding trough in conjunction with multiple groups of depth adjustment components, multiple groups of width adjustment components and multiple groups of length adjustment components, so that the effective depth, effective width and effective length of the feeding trough can be flexibly adjusted within a certain range, ensuring that the size of the peanut seeds can be matched when used for sowing of different varieties of peanut seeds, ensuring the smooth rotation of the feeding roller in the cylinder, and avoiding the situation where the rotation of the feeding roller may crush the peanut seeds, thereby ensuring the integrity of the peanut seeds; at the same time, the storage quantity of peanut seeds in the feeding trough can be accurately controlled to improve the uniformity of sowing.

[0040] 3. When the sowing depth needs to be adjusted in the present invention, by rotating the screw with the knob and cooperating with the guiding and limiting of the guide rod, the knob will drive the lifting plate to rise and fall, thereby driving multiple material guiding pipes to rise and fall simultaneously, achieving flexible adjustment of the sowing depth. Moreover, after loosening the second bolt, the lifting plate can slide relative to the sliding rod, so that the distance between adjacent adjusting blocks can be flexibly adjusted, making the lateral sowing distance between adjacent two groups of sowing components adjustable. As a result, the present invention can complete the sowing work of multiple rows of peanuts during a single forward movement, and both the column spacing and the lateral spacing can be flexibly adjusted, improving the sowing work efficiency while ensuring sowing uniformity, and also meeting different actual requirements in terms of sowing depth, thus further enhancing the practicality of the present invention.

One end of the width adjusting component away from the second mounting ring 44 is slidably inserted into two first slots 53 at corresponding positions. The width adjusting component is used to cooperate with the first ejector rod 63 in the first slot 53 to adjust the distance between the two side plates 61, so as to adjust the effective width of the material taking groove 59.

One end of the depth adjusting component away from the third mounting ring 46 is slidably inserted into the second slot 54 at the corresponding position. The depth adjusting component is used to cooperate with the second ejector rod 68 in the second slot 54 to adjust the height of the bottom plate 60 in the material taking groove 59, so as to adjust the effective depth of the material taking groove 59.

[0074] On the outer periphery of the second rotating shaft 24, at the position of the other end of the material taking roller 39, a first thread 40 is provided, and two symmetrically arranged limiting sliding grooves 41 are opened. A first adjusting ring 56 is threadedly installed on the outer periphery of the second rotating shaft 24 through the first thread 40. One end of the first adjusting ring 56 close to the material taking roller 39 is rotatably connected to a first mounting ring 55 sleeved on the outer periphery of the second rotating shaft 24. On the inner wall of the first mounting ring 55, two bumps are also fixedly connected and respectively slidably clamped in the two limiting sliding grooves 41. On the outer periphery of the first mounting ring 55, a plurality of length adjusting components equal in number to the plurality of material taking grooves 59 are fixedly connected. The plurality of length adjusting components are circumferentially arrayed about the axis of the first mounting ring 55. One end of the length adjusting component away from the first mounting ring 55 slides through the end face of the material taking roller 39 into the corresponding material taking groove 59.

[0075] AsFigure 8 and Figure 12 As shown in Figure 12 , the width adjustment assembly includes an L-shaped connecting rod 48 fixedly installed on the periphery of the second mounting ring 44. One end of the L-shaped connecting rod 48 away from the second mounting ring 44 is fixedly connected with a mounting strip 49. At both ends of the side of the mounting strip 49 away from the L-shaped connecting rod 48, a first inserting rod 50 is fixedly installed. One end of each of the two first inserting rods 50 away from the mounting strip 49 is respectively slidably inserted into two corresponding first slots 53;

[0076] One end of the first inserting rod 50 located in the first slot 53 is provided with a first inclined surface 67 for cooperating with the first chamfer 66.

[0077] As Figure 8 and Figure 13 As shown in Figure 13 , the depth adjustment assembly includes a convex plate 52 fixedly installed on the periphery of the third mounting ring 46. One end of the convex plate 52 away from the third mounting ring 46 is fixedly connected with a second inserting rod 51. One end of the second inserting rod 51 away from the convex plate 52 is slidably inserted into the corresponding second slot 54;

[0078] One end of the second inserting rod 51 located in the second slot 54 is provided with a second inclined surface 72 for cooperating with the second chamfer 69.

[0079] As Figure 8 and Figure 9 As shown in Figure 9 , the length adjustment assembly includes a connecting plate 57 fixedly installed on the periphery of the first mounting ring 55. One end of the connecting plate 57 away from the first mounting ring 55 is fixedly connected with a stop rod 58 arranged parallel to the axis of the material taking roller 39. One end of the stop rod 58 away from the connecting plate 57 slidably penetrates through the end face of the material taking roller 39 to the corresponding material taking groove 59;

[0080] The stop rod 58 is located above the bottom plate 60 and at the middle position between the two side plates 61. The diameter of the stop rod 58 is less than or equal to the width of the bottom plate 60. The sum of the diameter of the stop rod 58 and the thickness of the bottom plate 60 is less than the depth of the material taking groove 59. And when the bottom plate 60 is attached to the bottom surface of the material taking groove 59, there is a gap between the bottom plate 60 and the stop rod 58.

[0081] When the present invention is in use:

[0082] When sowing is not required, rotate the first bolt 18 to separate the first bolt 18 from the slot hole on the side surface of the first belt pulley 19. At this time, the first belt pulley 19 is rotatably connected with the first rotating shaft 4. Then the rotation of the first rotating shaft 4 will not drive the transmission assembly to operate, and the sowing mechanism is also in a stopped state. And the bottom ends of multiple groups of material guiding assemblies are lifted above the ground through the depth adjustment mechanism; at this time, the user can push the device main body to move through the handle 14.

[0083] During sowing, turn bolt 18 so that the front end of bolt 18 extends into the slot on the side of pulley 19. At this time, the circumferential relative rotation between pulley 19 and rotating shaft 4 is restricted. Then the rotation of rotating shaft 4 will drive the transmission assembly to operate, thereby driving the sowing mechanism to work, enabling the user to perform normal sowing work when pushing the device. Among them, through the coordinated setting of rotating shaft 4, pulley 19, limit ring 17 and bolt 18, a clutch effect is achieved between rotating shaft 4 and pulley 19, enabling flexible switching between the sowing mode (driving the sowing mechanism to sow during movement) and the moving mode (not performing sowing actions during movement) of the device, improving the convenience of use of the device.

[0084] In the transmission assembly, the rotation of pulley 19 drives pulley 2 to rotate through belt 8. Pulley 2 drives gearbox 6 to operate. Gearbox 6 drives pulley 3 to rotate. Pulley 3 drives pulley 4 to rotate through belt 11. Pulley 4 drives rotating shaft 2 to rotate. With the setting of coupling 26, it can drive multiple material taking rollers 39 to rotate simultaneously, thereby achieving the purpose of driving the sowing mechanism to operate during the movement of the device.

[0085] Among them, since the sowing mechanism is driven by the rotation of rotating shaft 4, when the number of material taking slots 59 is fixed and the transmission ratio of the transmission assembly is fixed, the columnar sowing spacing of peanuts is always a fixed value, that is, regardless of the pushing speed, peanuts can maintain a uniform sowing state. And when it is necessary to adjust the spacing, only the gearbox 6 needs to be adjusted. Therefore, through the transmission connection between rotating shaft 4 and the sowing mechanism by the transmission assembly, it is convenient for the user to flexibly adjust the columnar planting spacing of peanuts within a certain range according to actual needs, and can meet the sowing requirements of different varieties of peanuts in terms of planting spacing, thereby improving the practicability of the present invention. The gearbox 6 selects a stepless speed change box in the prior art. By changing the transmission ratio, the output speed can be smoothly adjusted without gear shifting, so that the columnar sowing spacing can be continuously and smoothly adjusted within a certain range, improving the spacing control accuracy and achieving the effect of improving the planting quality.

[0086] When it is necessary to control the single sowing quantity of peanut seeds:

[0087] The effective depth of the material taking slot 59 is the distance between the top opening of the material taking slot 59 and the top surface of the bottom plate 60. The effective width of the material taking slot 59 is the distance between the two side plates 61. The effective length of the material taking slot 59 is the distance between the end face of the retaining rod 58 located in the material taking slot 59 and the end face of the material taking slot 59 away from the first mounting ring 55. Before sowing, make applicable adjustments to the effective depth, effective width and effective length of the material taking slot 59 according to the size of peanut seeds. Specifically:

[0088] Adjustment of the effective depth of the seed-taking groove 59:

[0089] Rotate the adjusting ring III 47 so that the mounting ring III 46 moves linearly on the periphery of the rotating shaft II 24, driving the insertion rod II 51 to expand and contract in the insertion slot II 54; when sowing small peanut seeds, insert the insertion rod II 51 into the insertion slot II 54, and through the extrusion contact between the inclined surface II 72 and the chamfer II 69, the ejector rod II 68 gradually jacks up the bottom plate 60 until the effective depth of the seed-taking groove 59 is suitable for small peanut seeds; otherwise, rotate the adjusting ring III 47 in the reverse direction, driving the insertion rod II 51 to gradually retract outwards. Under the elastic force of the spring II 71, the ejector rod II 68 will drive the bottom plate 60 to move downward synchronously for reset until the effective depth of the seed-taking groove 59 is suitable for large peanut seeds.

[0090] Adjustment of the effective width of the seed-taking groove 59:

[0091] Rotate the adjusting ring II 45 so that the mounting ring II 44 moves linearly on the periphery of the rotating shaft II 24, driving the insertion rod I 50 to expand and contract in the insertion slot I 53; when sowing small peanut seeds, insert the insertion rod I 50 into the insertion slot I 53, and through the extrusion contact between the inclined surface I 67 and the chamfer I 66, the ejector rod I 63 gradually pushes out the side plates 61, and the two side plates 61 move closer synchronously until the effective width of the seed-taking groove 59 is suitable for small peanut seeds; otherwise, drive the insertion rod I 50 to gradually retract outwards. Under the elastic force of the spring I 65, the ejector rod I 63 will drive the side plates 61 to move synchronously for reset, and the two side plates 61 move away from each other synchronously until the effective width of the seed-taking groove 59 is suitable for large peanut seeds.

[0092] Adjustment of the effective length of the seed-taking groove 59:

[0093] Rotate the adjusting ring I 56, driving the mounting ring I 55 to move linearly on the periphery of the rotating shaft II 24, thereby changing the insertion length of the stop rod 58 in the seed-taking groove 59. The inserted part of the stop rod 58 will block the peanut seeds, so that the effective length of the seed-taking groove 59 can be adjusted; the longer the effective length of the seed-taking groove 59, the more the number of seeds taken at a time, and vice versa.

[0094] Therefore, in the present invention, by setting a space limiting mechanism in the material taking groove 59 in cooperation with multiple sets of depth adjusting components, multiple sets of width adjusting components, and multiple sets of length adjusting components, the effective depth, effective width, and effective length of the material taking groove 59 can be flexibly adjusted within a certain range, ensuring that it can fit the size of peanut seeds when used for sowing different varieties of peanut seeds, guaranteeing the smooth rotation of the material taking roller 39 in the cylinder 35, and also avoiding the situation that the rotation of the material taking roller 39 may crush the peanut seeds, ensuring the integrity of the peanut seeds; at the same time, the storage quantity of peanut seeds in the material taking groove 59 can be accurately controlled by changing the effective length of the material taking groove 59, improving the sowing uniformity and the emergence rate. This flexible structural design enables quick switching between different peanut varieties, thereby improving the sowing efficiency and reducing the time loss during the sowing process, especially in the case of a short planting area.

[0095] Embodiment 2:

[0096] Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 Based on Embodiment 1, the material guiding component includes a telescopic corrugated pipe 31. The top end of the telescopic corrugated pipe 31 is fixedly connected to the bottom end of the feeding pipe 38. The bottom end of the telescopic corrugated pipe 31 passes through the through groove 13 to the lower side of the vehicle plate 1 and is fixedly connected to a material guiding pipe 32. The lower part of the material guiding pipe 32 is a bent structure, and the bending direction is close to the tail end of the vehicle plate 1;

[0097] A soil covering member is fixedly connected to the side surface of the vertical part of the material guiding pipe 32 close to the tail end of the vehicle plate 1.

[0098] The soil covering member includes a Y-shaped connecting rod 33. Both forked ends of the Y-shaped connecting rod 33 are fixedly connected with vertically arranged soil covering plates 34. The two soil covering plates 34 are symmetrically arranged in a V-shape and are respectively located on both sides of the material guiding pipe 32. There is a gap between the soil covering plates 34 and the material guiding pipe 32. The side with the larger opening of the two soil covering plates 34 is the side close to the material guiding pipe 32, and the closest distance between the two soil covering plates 34 is equal to the width of the material guiding pipe 32. The bottom surface of the soil covering plate 34 is located between the top and bottom ends of the discharge port of the material guiding pipe 32.

[0099] During sowing, the bottom end of the material guiding pipe 32 and the bottom end of the soil covering plates 34 both extend into the soil. During the movement of the device, the material guiding pipe 32 forms a sowing groove on the ridge. The peanut seeds dropped by the feeding component pass through the telescopic corrugated pipe 31 and the material guiding pipe 32 and fall into the sowing groove. Immediately afterwards, the movement of the two soil covering plates 34 will guide the soil on both sides of the sowing groove into the sowing groove, thus realizing continuous ditch opening, sowing, and soil covering operations.

[0100] Embodiment 3:

[0101] Please refer toFigure 1 , Figure 3 and Figure 5 , on the basis of Embodiment 2, the depth adjustment mechanism includes a lifting plate 20 horizontally arranged at the middle position below the vehicle board 1.

A plurality of adjusting blocks 30 equal in number to the number of groups of material guiding components are slidably installed on the outer periphery of the two slide bars 28. One ends of the plurality of adjusting blocks 30 away from the lifting plate 20 are respectively fixedly connected to the sides of the vertical parts of the plurality of material guiding pipes 32 close to the front end of the vehicle board 1; a bolt two 29 for restricting the relative sliding movement between the adjusting block 30 and the slide bar 28 is threadedly installed through the bottom surface of the adjusting block 30;

[0102] At the middle position of the top surface of the lifting plate 20, a vertically arranged screw rod 22 is rotatably installed. The top end of the screw rod 22 threadedly penetrates the bottom surface of the vehicle board 1 to the upper part of the vehicle board 1, and a knob 23 is fixedly installed;

[0103] On the top surface of the lifting plate 20, two guide rods 21 symmetrically arranged with respect to the screw rod 22 are also fixedly connected. The top ends of the guide rods 21 slidably penetrate the bottom surface of the vehicle board 1 to the upper part of the vehicle board 1.

[0104] When it is necessary to adjust the sowing depth, by rotating the screw rod 22 through the knob 23, and with the guiding and limiting of the guide rod 21, the knob 23 will drive the lifting plate 20 to rise and fall, thereby simultaneously driving the plurality of material guiding pipes 32 to rise and fall, realizing flexible adjustment of the sowing depth;

[0105] Moreover, after loosening the bolt two 29, the lifting plate 20 and the slide bar 28 can slide, so that the distance between two adjacent adjusting blocks 30 can be flexibly adjusted, making the lateral sowing spacing between two adjacent groups of sowing components 16 adjustable. Thus, the present invention can complete the sowing work of multiple rows of peanuts during a single travel, and both the column spacing and the lateral spacing can be flexibly adjusted, improving the sowing work efficiency while ensuring sowing uniformity, and can also meet different actual requirements in terms of sowing depth, thereby further improving the practicality of the present invention.
