Abstract
Description
Technical Field
[0001] This utility model relates to a peanut planting device for agricultural machinery. Background Technology
[0002] Peanuts, as an important oilseed and cash crop, typically involve multiple steps in their cultivation, including ditching, sowing, and covering with soil. Under traditional manual or semi-mechanized sowing methods, these steps must be performed in stages, resulting in high labor intensity, low sowing efficiency, and uneven plant spacing and depth, directly impacting peanut emergence rate and subsequent yield.
[0003] Therefore, based on existing agricultural machinery, we designed a peanut planting device for agricultural machinery that uses a dragging motion to achieve efficient planting. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a peanut planting device for agricultural machinery that can achieve efficient planting by dragging forward.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] A peanut planting device for agricultural machinery, comprising:
[0007] The vehicle structure is towed forward by agricultural machinery.
[0008] A trenching device is installed at the bottom of the vehicle structure, and one or more trenching devices are provided.
[0009] The sowing mechanism is installed via the carrier structure and corresponds to the furrowing device. The sowing mechanism sows seeds into the planting furrows opened by the furrowing device.
[0010] A soil covering mechanism is installed via the carrier structure and uses the soil covering mechanism to re-cover the soil removed by the trenching device into the planting trench.
[0011] Preferably, the vehicle structure includes a vehicle plate and a connecting plate, the connecting plate being used to connect agricultural machinery, the lower end of the connecting plate being rotatably connected to the vehicle plate, and a telescopic rod being rotatably installed between the connecting plate and the vehicle plate.
[0012] Preferably, the telescopic rod is an electrically operated telescopic rod.
[0013] Preferably, the ditching device includes a ditching plate, which is V-shaped with its tip pointing in the direction of agricultural machinery movement, and the ditching plate is fixed to the bottom of the carrier plate.
[0014] Preferably, the sowing mechanism includes a cover, a rotating wheel, a first rotating shaft, a feeding box, and a first power unit. The rotating wheel is coaxially mounted inside the cover. The first rotating shaft passes through the axis of the rotating wheel and the cover, and is fixed to the rotating wheel. A bearing and a shaft seal are fitted between the first rotating shaft and the cover. The lower part of the cover has an opening, and a portion of the rotating wheel is located outside the opening. A through groove for mounting the cover is provided on the top of the carrier plate. The cover is fixed to the carrier plate, and the lower end of the cover extends through the through groove to the feed box. Below the carrier plate, the power unit is fixedly installed via the carrier plate. A first transmission unit is connected between the power unit and the rotating shaft. Multiple seed grooves are distributed in a ring on the outer circumference of the rotating wheel. The distance between the outer circumference of the rotating wheel and the inner wall of the cover is less than 1 mm. A feeding pipe is provided at the top center of the cover, and the feeding box is installed at the upper end of the feeding pipe. The rotating wheel corresponds to the ditching plate and rotates in the planting groove opened by the ditching plate so that the peanut seeds falling into the seed groove are sown into the planting groove.
[0015] Preferably, a cleaning mechanism is installed at the upper end of the opening, and the cleaning mechanism cleans the seed trough.
[0016] Preferably, the cleaning mechanism includes an outer tube, a sliding plate, a guide rod, an outer bracket, a nut, a spring, and brush bristles. The outer tube is integrally formed with the cover. A stepped hole is provided on the end face of the outer tube facing the rotating wheel, with the larger diameter portion of the stepped hole located at the bottom and the smaller diameter portion at the top. The sliding plate is slidably installed at the larger diameter portion of the stepped hole. The guide rod is inserted from the smaller diameter portion of the stepped hole and fixedly connected to the sliding plate. The spring is sleeved on the guide rod and acts between the outer tube and the sliding plate. The brush bristles are embedded in the end of the sliding plate away from the guide rod. The outer bracket is fixed to the outer end face of the outer tube. The end of the guide rod away from the sliding plate passes upward through the outer bracket and engages with the nut. The brush bristles clean the seed trough as they descend.
[0017] Preferably, a rubber cup is fixed to the inner wall of the seed trough.
[0018] Preferably, the soil covering mechanism includes a roller and a second power device. A second rotating shaft is fixed at the center of the roller, and a bearing seat is fixed on the carrier plate. A first bearing is fitted between the second rotating shaft and the bearing seat. The second power device is fixedly installed through the carrier plate. A second transmission unit is fitted between the second power device and the second rotating shaft. Conical mudguards are provided at both ends of the roller.
[0019] The beneficial effects of this utility model are:
[0020] By integrating the ditching device, sowing mechanism, and soil covering mechanism onto the same carrier structure, ditching, sowing, and soil covering can be completed continuously in one go, greatly reducing the number of operation steps, significantly improving sowing efficiency, and reducing the intensity of manual labor. It adopts a towable forward movement and can be directly installed with agricultural machinery.
[0021] Each seed trough can hold a fixed number of seeds, ensuring uniform sowing. By controlling the rotation speed of the primary power unit, the forward speed of the agricultural machinery can be easily matched, thereby precisely controlling the plant spacing to meet the requirements of different planting patterns.
[0022] The gap between the rotating wheel of the sowing mechanism and the inner wall of the cover is extremely small (less than 1mm), and a dedicated cleaning mechanism is structurally designed. The spring-pressed bristles continuously clean the rotating wheel and seed trough, effectively preventing soil adhesion and blockage, and ensuring the reliability and continuity of sowing under humid conditions.
[0023] An elastic rubber cup is installed in the seed trough, which plays a good role in buffering and protecting the peanut kernels during the sowing process, reducing mechanical damage and improving the seed germination rate.
[0024] The carrier structure adopts a tilting design controlled by an electric telescopic rod, which can lower the seeding device to a horizontal working state during operation; when not in operation (such as during relocation or transportation), it can be lifted as a whole, so that the working parts are completely off the ground. This makes operation flexible and convenient, protects the device from damage, and improves the equipment's passability and service life.
[0025] The soil covering mechanism uses an actively rotating roller equipped with a conical mudguard, which can evenly and smoothly backfill the soil into the planting trench without pushing the soil to the sides, resulting in better soil covering and promoting seed germination and growth.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0039] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0041] See Figure 1 The peanut planting device for agricultural machinery shown includes:
[0042] Vehicle structure 1, which is towed forward by agricultural machinery.
[0043] A trenching device 2 is installed at the bottom of the carrier structure 1. There is one or more trenching devices 2. In this embodiment, there are two trenching devices 2, which are arranged in parallel along the width direction of the carrier plate 11.
[0044] The sowing mechanism 3 is installed through the carrier structure 1. The sowing mechanism 3 corresponds to the furrowing device 2. The sowing mechanism 3 sows seeds into the planting furrows opened by the furrowing device 2.
[0045] The soil covering mechanism 4 is installed through the carrier structure 1. The soil covering mechanism 4 re-covers the soil that has been removed by the trenching device 2 into the planting trench.
[0046] The above technical solution integrates ditching, sowing, and covering with soil into a single operation, which greatly enables continuous sowing of peanuts and improves sowing efficiency.
[0047] See Figure 1 As shown, the vehicle structure 1 includes a vehicle plate 11 and a connecting plate 12. The connecting plate 12 is used to connect agricultural machinery. The connection between the connecting plate 12 and the agricultural machinery is a bolt connection. The lower end of the connecting plate 12 is rotatably connected to the vehicle plate 11 by means of a pin rotation. A telescopic rod 13 is rotatably installed between the connecting plate 12 and the vehicle plate 11. The telescopic rod 13 is an electric telescopic rod. The electric telescopic rod is powered by the agricultural machinery's built-in power supply and is equipped with a controller to control its extension and retraction. The controller is integrated into the cab of the agricultural machinery.
[0048] In the above technical solution, during sowing, the telescopic rod 13 is raised, causing the carrier plate 11 to rotate to a horizontal or near-horizontal state.
[0049] After sowing is completed, the retraction of the telescopic rod 13 causes the carrier plate 11 to rotate along the pin shaft, thereby raising the carrier plate 11 and causing the furrowing device 2, the sowing mechanism 3, and the soil covering mechanism 4 to detach from the ground.
[0050] See Figure 2 As shown, the ditching device 2 includes a ditching plate 21, which is V-shaped with its tip pointing towards the direction of agricultural machinery movement. The ditching plate 21 is fixed to the bottom of the carrier plate 11.
[0051] The height of the furrowing plate 21 is set according to the required planting depth. For example, in conventional peanut planting, which is shallow planting, a planting depth of about 8cm is usually sufficient. Therefore, when the soil covering mechanism 4 contacts the raised ridge, the furrowing plate 21 is inserted into the ridge to a depth of 8cm.
[0052] See Figures 2 to 5 As shown, the sowing mechanism 3 includes a cover 31, a rotating wheel 32, a first rotating shaft 33, a feeding box 34, and a first power unit 35. The rotating wheel 32 is coaxially installed inside the cover 31. The first rotating shaft 33 passes through the axis of the rotating wheel 32 and the cover 31. The first rotating shaft 33 is fixed to the rotating wheel 32. A bearing (not shown) and a shaft seal (not shown) are fitted between the first rotating shaft 33 and the cover 31. When there are two or more sowing mechanisms 3, the two or more sowing mechanisms 3 share a first rotating shaft 33, so that multiple sowing mechanisms 3 only need one first power unit 35 to drive them. The lower part of the cover 31 has an opening 310, and the rotating wheel 32 is partially located outside the opening 310. A through groove (not shown) for mounting the cover 31 is provided on the top of the carrier plate 11. The cover 31 is fixed to the carrier plate 11, and the lower end of the cover 31 extends below the carrier plate 11 through the through groove. The first power unit 35 is fixedly mounted on the carrier plate 11. A first transmission unit 36 is connected between the first power unit and the rotating shaft 33. The first power unit 35 is a conventional motor powered by an agricultural machinery power supply and equipped with a speed regulator. The first transmission unit 36 is a synchronous motor. A toothed belt drive unit; multiple seed grooves 320 are distributed in a ring on the outer circular surface of the rotating wheel 32. The distance between the outer circular surface of the rotating wheel 32 and the inner wall of the cover 31 is less than 1 mm. The purpose of this design is to prevent peanut seeds from getting stuck between the rotating wheel 32 and the cover 31. A feeding pipe 311 is provided at the top center of the cover 31. The feeding box 34 is installed at the upper end of the feeding pipe 311. The feeding box 34 has a detachable box cover 341. The rotating wheel 32 corresponds to the ditching plate 21. The rotating wheel 32 rotates in the planting groove opened by the ditching plate 21 so that the peanut seeds falling into the seed grooves 320 are sown into the planting groove.
[0053] In the above technical solution, when the seed trough 320 corresponds to the feeding pipe 311, the peanut seeds located in the feeding pipe 311 will fall into the seed trough 320 by rotating the wheel 32.
[0054] Each planting trough, with a capacity of 320, can hold 2 to 3 peanut seeds.
[0055] The output speed of the first power unit 35 is adjusted according to the forward speed of the vehicle to maintain a more suitable plant spacing.
[0056] See Figure 3 , Figure 4 and Figure 5 As shown, a cleaning mechanism is installed at the upper end of the opening, and the cleaning mechanism cleans the seed trough.
[0057] The cleaning mechanism includes an outer tube 51, a sliding plate 52, a guide rod 53, an outer bracket 54, a nut 55, a spring 56, and bristles 58. The outer tube 51 is integrally formed with the cover 31. A stepped hole 57 is provided on the end face of the outer tube 51 facing the rotating wheel 32. The larger diameter portion of the stepped hole 57 is located at the bottom, and the smaller diameter portion is located at the top. The sliding plate 52 is slidably installed on the larger diameter portion of the stepped hole 57. The guide rod 53 is inserted from the smaller diameter portion of the stepped hole 57 and is fixedly connected to the sliding plate 52. The spring 56 is sleeved on the guide rod 53 and acts between the outer tube 51 and the sliding plate 52. The bristles 58 are inserted into the end of the sliding plate 52 away from the guide rod 53. The outer bracket 54 is fixed to the outer end face of the outer tube 51. The end of the guide rod 53 away from the sliding plate 52 passes upward through the outer bracket 54 and engages with the nut 55. The bristles 58 clean the seed trough 320 after descending.
[0058] In the above technical solution, during the rotation of the wheel 32, the bristles 58 clean the seed trough 320 and the outer surface of the wheel 32, so that the attached soil is removed and the chance of mud entering the wheel 32 is reduced.
[0059] See Figure 4 As shown, a rubber cup 333 is fixed to the inner wall of the seed groove 320.
[0060] Rubber cup 333 has a certain degree of elasticity, which provides some protection for the seeds.
[0061] See Figure 2As shown, the soil covering mechanism 4 includes a roller 41 and a second power device 42. A second rotating shaft 43 is fixed at the axis of the roller 41. A bearing seat 44 is fixed on the carrier plate 11. A first bearing (not shown) is fitted between the second rotating shaft 43 and the bearing seat 44. The second power device 42 is fixedly installed through the carrier plate 11. A second transmission unit 45 is fitted between the second power device 42 and the second rotating shaft 43. Conical mudguards 46 are provided at both ends of the roller 41. The mudguards 46 are welded to the roller 41.
[0062] In the above technical solution, the second power device 42 is also a conventional motor, which is also equipped with a speed regulator. When covering the soil, the second power device 42 drives the roller 41 to rotate. The rotation of the roller 41 drives the soil on the ridge to cover the planting furrow, thus achieving seed covering.
[0063] The mudguards at both ends are located on both sides of the ridge. The conical mudguards 46 are used to limit the range of soil rolling and ensure that the soil covering operation is concentrated in the planting trench.
[0064] The second transmission unit 45 is a synchronous belt transmission unit.
