Description

Technical Field

[0001] The invention relates to the technical field of peanut planting devices, in particular to a peanut sowing device. Background Art

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

[0003] In the prior art, there is a patent with application number 202410277089.X, which provides a light and precise peanut sowing device for hilly and mountainous areas, including a cart, a movable planting assembly and a feeding assembly mounted on the cart; the cart includes a frame, a moving wheel mounted on the bottom of the frame, and a handrail mounted on the frame; the movable planting assembly includes a perforated planting part, and a rotary drive part; wherein the perforated planting part includes a slidably sleeved transverse moving tube and a perforated tube, and the transverse moving tube is vertically arranged. The present invention has a small size and a light weight, and can keep the perforated tube and the cart relatively stationary during the movement of the cart and vertically insert it into the ground to perform perforated planting work.

[0004] However, the sowing device provided by the above patent still has the following shortcomings during use: 1. According to its content, the spacing of row sowing is a fixed value, and the sowing depth is also a fixed value, but there are actually different requirements for the spacing and sowing depth of peanut spot sowing. For example, different peanut varieties may have different requirements for spacing and depth. Some high-yield or large peanut varieties require larger spacing to ensure that the plants have enough space to grow. In deep, fertile soils, smaller spot sowing spacing can be used, while in poor or shallow soils, larger spacing is required to avoid plant competition for nutrients. In loose, loose soils, sowing can be appropriately deepened, while in heavy clay soils, the appropriate sowing depth should be maintained to ensure a good germination rate.

[0005] 2. According to its content, quantitative feeding of peanut seeds is achieved through the coordinated setting of the feeding wheel and the feeding trough; however, in the actual sowing of peanuts, since there are different varieties of peanuts, their seeds often have different sizes. Therefore, the above-mentioned sowing device is only suitable for sowing of peanuts of specified varieties. When the size of the peanut seeds changes, the number of seeds that can be accommodated in the feeding trough is prone to change, thereby reducing the quality of peanut sowing work. Its practicality needs to be improved. Summary of the invention

[0019] 3. When the sowing depth needs to be adjusted, the present invention rotates the screw rod by turning the knob, and in cooperation with the guide limit of the guide rod, the knob will drive the lifting plate to move up and down, thereby driving multiple material guide tubes to move up and down at the same time, thereby realizing flexible adjustment of the sowing depth; and, after loosening the second bolt, the lifting plate and the slide rod can slide, so that the distance between two adjacent adjustment blocks can be flexibly adjusted, so that the lateral sowing spacing between two adjacent groups of sowing components can be adjusted, so that the present invention can complete the sowing of multiple rows of peanuts in a single process during sowing, and both the row spacing and the lateral spacing can be flexibly adjusted, which improves the sowing work efficiency while ensuring the sowing uniformity, and can also meet different actual needs in terms of sowing depth, thereby further improving the practicality of the present invention.

Two protrusions that are slidably clamped in the two limiting slide grooves 41 are also fixedly connected to the inner wall of the mounting ring 55; a plurality of groups of length adjustment components equal to the number of the plurality of feeding grooves 59 are fixedly connected to the periphery of the mounting ring 55, and the plurality of groups of length adjustment components are distributed in a circumferential array about the axis of the mounting ring 55, and the end of the length adjustment component away from the mounting ring 55 slides through the end surface of the feeding roller 39 to the corresponding feeding groove 59.

[0026] like Figure 8 and Fig.12 As shown, the width adjustment assembly includes an L-shaped connecting rod 48 fixedly mounted 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 to a mounting strip 49, and both ends of the side of the mounting strip 49 away from the L-shaped connecting rod 48 are fixedly mounted with an insertion rod 1 50, and one end of the two insertion rods 1 50 away from the mounting strip 49 is respectively slidably inserted into two slots 1 53 at corresponding positions; One end of the insertion rod 50 located in the slot 53 is provided with a slope 67 used in conjunction with the chamfer 66 .

[0027] like Figure 8 and Fig.13 As shown, the depth adjustment assembly includes a convex plate 52 fixedly mounted on the periphery of the mounting ring 3 46, and an end of the convex plate 52 away from the mounting ring 3 46 is fixedly connected to a second insertion rod 51, and an end of the second insertion rod 51 away from the convex plate 52 is slidably inserted into the corresponding convex plate 52; One end of the second insertion rod 51 located in the second slot 54 is provided with a second inclined surface 72 used in conjunction with the second chamfer 69 .

[0028] like Figure 8 and Fig. 9 As shown, the length adjustment assembly includes a connecting plate 57 fixedly mounted on the periphery of the mounting ring 1 55, and one end of the connecting plate 57 away from the mounting ring 1 55 is fixedly connected to a stopper 58 arranged parallel to the axis of the material taking roller 39, and one end of the stopper 58 away from the connecting plate 57 slides through the end surface of the material taking roller 39 to the corresponding material taking groove 59; The baffle rod 58 is located above the bottom plate 60 and in the middle of the two side plates 61. The diameter of the baffle rod 58 is less than or equal to the width of the bottom plate 60. The sum of the diameter of the baffle rod 58 and the thickness of the bottom plate 60 is less than the depth of the material trough 59. When the bottom plate 60 is attached to the bottom surface of the material trough 59, there is a gap between the bottom plate 60 and the baffle rod 58.

[0029] When the present invention is used: When sowing is not needed, bolt 18 is rotated to separate bolt 18 from the slot on the side of pulley 19. At this time, pulley 19 and shaft 4 are rotationally connected, and the rotation of shaft 4 will not drive the transmission assembly to operate, so the sowing mechanism is also in a stopped state, and the bottom ends of the multiple groups of material guide assemblies are lifted above the ground through the depth adjustment mechanism; at this time, the user can push the device body to move by the handle 14.

[0030] When sowing, the bolt 18 is rotated so that the front end of the bolt 18 extends into the slot on the side of the pulley 19. At this time, the circumferential relative rotation between the pulley 19 and the rotating shaft 4 is restricted, and the rotation of the rotating shaft 4 will drive the transmission component to operate, thereby driving the sowing mechanism to work, so that the user can perform normal sowing work when pushing the device; wherein, through the coordinated arrangement of the rotating shaft 4, the pulley 19, the limiting ring 17 and the bolt 18, a clutch effect is provided between the rotating shaft 4 and the pulley 19, and the device can be flexibly switched between the sowing mode (synchronously driving the sowing mechanism to sow during the movement) and the moving mode (no sowing action is performed during the movement), thereby improving the use convenience of the device.

[0031] In the transmission assembly, the rotation of pulley 19 drives pulley 2 9 to rotate through belt 1 8, pulley 2 9 drives gear box 6 to operate, gear box 6 drives pulley 3 10 to rotate, pulley 3 10 drives pulley 4 12 to rotate through belt 2 11, and pulley 4 12 drives shaft 2 24 to rotate. With the setting of coupling 26, multiple feeding rollers 39 can be driven to rotate at the same time, thereby achieving the purpose of driving the sowing mechanism to operate during the movement of the device; Among them, since the sowing mechanism is driven by the rotation of the rotating shaft 14, when the number of the feeding troughs 59 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 6 needs to be adjusted. Therefore, the setting of the transmission connection between the rotating shaft 14 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. The gear box 6 uses a continuously variable transmission in the prior art. By changing the transmission ratio, the output speed can be adjusted smoothly without shifting the gear, so that the row-wise sowing spacing can be adjusted continuously and smoothly within a certain range, improving the spacing control accuracy, and achieving the effect of improving the planting quality.

[0032] When it is necessary to control the number of peanut seeds sown at a time: The effective depth of the feeding trough 59 is the distance between the top opening of the feeding trough 59 and the top surface of the bottom plate 60; the effective width of the feeding trough 59 is the distance between the two side plates 61; the effective length of the feeding trough 59 is the distance between the end surface of the blocking rod 58 located in the feeding trough 59 and the end surface of the feeding trough 59 away from the mounting ring 1 55; before sowing, the effective depth, effective width and effective length of the feeding trough 59 are adjusted according to the size of the peanut seeds; specifically: Effective depth adjustment of the material taking trough 59: Rotate the adjusting ring 3 47 to make the mounting ring 3 46 move linearly on the periphery of the rotating shaft 24, driving the insert rod 2 51 to extend and retract in the slot 2 54; when sowing small-fruit peanut seeds, extend the insert rod 2 51 into the slot 2 54, and through the extrusion contact between the inclined surface 2 72 and the chamfer 2 69, the push rod 2 68 gradually lifts the bottom plate 60 until the effective depth of the material trough 59 is suitable for small-fruit peanut seeds; conversely, rotate the adjusting ring 3 47 in the opposite direction to drive the insert rod 2 51 to gradually retract outward, and under the elastic force of the spring 2 71, the push rod 2 68 will drive the bottom plate 60 to reset and move downward synchronously until the effective depth of the material trough 59 is suitable for large-fruit peanut seeds.

[0033] Adjustment of the effective width of the material taking trough 59: Rotate the adjusting ring 45 to make the mounting ring 44 move linearly on the periphery of the rotating shaft 24, driving the insert rod 50 to extend and retract in the slot 53; when sowing small-fruit peanut seeds, make the insert rod 50 extend into the slot 53, and through the extrusion contact between the inclined surface 67 and the chamfer 66, make the push rod 63 gradually push out the side plate 61, and the two side plates 61 move synchronously close to each other until the effective width of the feeding trough 59 is suitable for small-fruit peanut seeds; conversely, drive the insert rod 50 to gradually retract outward, and under the elastic force of the spring 65, the push rod 63 will drive the side plates 61 to perform synchronous reset movement, and the two side plates 61 will synchronously move away from each other until the effective width of the feeding trough 59 is suitable for large-fruit peanut seeds.

[0034] Adjustment of the effective length of the material taking trough 59: Rotate the adjusting ring 56 to drive the mounting ring 55 to perform linear motion on the periphery of the rotating shaft 2 24, thereby changing the extending length of the blocking rod 58 in the feeding trough 59. The extending part of the blocking rod 58 will block the peanut seeds, thereby adjusting the effective length of the feeding trough 59; the longer the effective length of the feeding trough 59, the more seeds can be taken at a single time, and vice versa.

[0035] Therefore, in the present invention, by setting a space limiting mechanism in the feeding trough 59 in conjunction with the setting of multiple groups of depth adjustment components, multiple groups of width adjustment components and multiple groups of length adjustment components, the effective depth, effective width and effective length of the feeding trough 59 can be flexibly adjusted within a certain range, ensuring that the size of the peanut seeds can be matched when used for sowing different varieties of peanut seeds, ensuring the smoothness of the rotation of the feeding roller 39 in the cylinder 35, and avoiding the situation where the rotation of the feeding roller 39 may crush the peanut seeds, thereby ensuring the integrity of the peanut seeds; at the same time, the effective length of the feeding trough 59 can be changed to accurately control the storage quantity of peanut seeds in the feeding trough 59, improve the uniformity of sowing, and increase the emergence rate. This flexible structural design allows for rapid switching between different peanut varieties, thereby improving sowing efficiency and reducing time loss during sowing, especially when the planting interval is short.

[0036] Embodiment 2: See also Figure 1 , Figure 3 , Figure 5 and Figure 6 On the basis of Example 1, the material guide assembly includes a telescopic bellows 31, the top of which is fixedly connected to the bottom of the feed tube 38, the bottom of which passes through the through slot 13 to the bottom of the vehicle plate 1, and is fixedly connected to a material guide tube 32, the lower part of which is a bent structure, and the bending direction is close to the rear end of the vehicle plate 1; A soil covering piece is fixedly connected to the side surface of the vertical portion of the material guide pipe 32 close to the rear end of the vehicle plate 1 .

[0037] The covering member includes a Y-shaped connecting rod 33, and both ends of the fork of the Y-shaped connecting rod 33 are fixedly connected with vertically arranged covering plates 34. The two covering plates 34 are arranged symmetrically in an eight-shaped shape and are respectively located on both sides of the material guide pipe 32. There is a distance between the covering plates 34 and the material guide pipe 32. The side with the larger opening of the two covering plates 34 is located close to the side of the material guide pipe 32, and the shortest distance between the two covering plates 34 is equal to the width of the material guide pipe 32. The bottom surface of the covering plate 34 is located between the top and bottom ends of the material outlet of the material guide pipe 32.

[0038] During sowing, the bottom ends of the guide pipe 32 and the covering plate 34 extend into the soil. During the movement of the device, the guide pipe 32 forms a sowing furrow on the ridge, and the peanut seeds dropped by the feeding assembly fall into the sowing furrow through the telescopic bellows 31 and the guide pipe 32. Then, the movement of the two covering plates 34 guides the soil on both sides of the sowing furrow into the sowing furrow, thereby realizing continuous furrowing, sowing and covering operations.

A plurality of adjustment blocks 30 equal to the number of the plurality of material guide components are slidably installed on the periphery of the two slide bars 28, and the ends of the plurality of adjustment blocks 30 away from the lifting plate 20 are respectively fixedly connected to the side surfaces of the vertical parts of the plurality of material guide pipes 32 close to the front end of the vehicle plate 1; the bottom surface of the adjustment block 30 is threadedly installed with a bolt 29 for limiting the relative sliding movement between the adjustment block 30 and the slide bar 28; A vertically arranged screw rod 22 is rotatably mounted in the middle of the top surface of the lifting plate 20. The top thread of the screw rod 22 penetrates the bottom surface of the vehicle plate 1 to the top of the vehicle plate 1, and a knob 23 is fixedly mounted thereon. Two guide rods 21 symmetrically arranged about the screw rod 22 are fixedly connected to the top surface of the lifting plate 20 , and the top ends of the guide rods 21 slide through the bottom surface of the vehicle plate 1 to the top of the vehicle plate 1 .

[0040] When the sowing depth needs to be adjusted, the screw rod 22 is rotated by the knob 23, and the knob 23 drives the lifting plate 20 to move up and down in coordination with the guide limit of the guide rod 21, thereby driving the multiple guide tubes 32 to move up and down at the same time, thereby realizing flexible adjustment of the sowing depth; Furthermore, by loosening the second bolt 29, the lifting plate 20 and the slide rod 28 can slide, and the distance between two adjacent adjustment blocks 30 can be flexibly adjusted, so that the lateral sowing spacing between two adjacent groups of sowing assemblies 16 can be adjusted, so that the present invention can complete the sowing of multiple rows of peanuts in a single process during sowing, and both the row spacing and the lateral spacing can be flexibly adjusted, which improves the sowing efficiency while ensuring the sowing uniformity, and can also meet different actual needs in terms of sowing depth, thereby further improving the practicality of the present invention.
