Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a corn planter that prevents clumping and clogging. Background Technology

[0002] A corn planter is an agricultural machine that sows corn seeds. It is primarily used to plant seeds into the soil, offering high efficiency and precision. Existing corn planters use a seed metering device to evenly plant corn seeds at set intervals. Subsequent processes such as fertilization, covering with soil, and compaction ensure a high germination rate. However, during the corn planting process, corn seeds are easily clump together due to compression during packaging and stacking before planting. When these clumps accumulate at the discharge port, they can clog the outlet, preventing corn seeds from entering the seed metering device or causing clumps to enter the device without being dispersed and planted directly into the soil. This negatively impacts the overall planting process and corn yield.

[0003] In response, Chinese patent application number CN219876840U discloses an anti-clogging device for a seeder's box, comprising an outer shell, a mounting box 1 fixedly connected to the lower end of the outer shell, a mounting box 2 fixedly mounted on the left side of the mounting box 1, a storage trough inside the outer shell, a detachable outer shell cover at the upper end of the storage trough, a stirring component inside the storage trough, a mounting slot 1 inside the mounting box 1, a mounting slot 2 inside the mounting box 2, and a sowing component inside both mounting slots 1 and 2. This structure is simple in design and can effectively prevent clogging of the discharge port during sowing through the cooperation between the sowing component and the stirring component, thus affecting sowing efficiency. However, this device only prevents clogging in the upper part of the seeder box, while failing to prevent clumping in the lower part, making it prone to leakage and increasing the risk of clogging.

[0004] Therefore, in order to solve the above problems, there is an urgent need to provide a reliable and stable corn planter that can effectively prevent corn seeds from clumping at the discharge port, so as to provide favorable conditions for the smooth progress of the planting work.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0022] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0023] Please refer to Figures 1-3 The contents are shown to better understand the specific structure of this utility model. This application provides a corn planter that prevents clumping and clogging, according to some of its embodiments, such as... Figure 1 As shown, the corn planter includes: a feeding unit 1, an anti-caking unit 2, and a planting unit 3.

[0024] In this embodiment, as Figure 1 As shown, the feeding unit 1 is located at the top of the seeder and is used to receive corn seeds to be sown. The feeding unit 1 may include a feeding hopper 101 and a conveying pipe 102. The feeding hopper 101 is located at the top of the feeding unit 1 and may be funnel-shaped. The conveying pipe 102 is located below the discharge port of the feeding hopper 101 and is connected to the discharge port by welding or other means. The lower end of the conveying pipe 102 is connected to the anti-caking unit 2 by welding or other means.

[0025] In this embodiment, the conveying pipe 102 is designed to avoid the upper structure of the anti-clogging unit 2, and is constructed using a double-pipe configuration. This structure maintains the material feeding speed while avoiding the structure.

[0026] In this embodiment, as Figure 2 As shown, the anti-clogging unit 2 has a housing 201 on the outside, and the housing 201 contains a first anti-clogging mechanism 202 and a second anti-clogging mechanism 203.

[0027] In this embodiment, the first anti-clumping mechanism 202 is disposed above the second anti-clumping mechanism 203, and is used to initially disperse the corn seeds entering the anti-clumping unit 2.

[0028] In this embodiment, the second anti-caking mechanism 203 is located near the discharge port of the anti-caking unit 2 and is used to disperse corn seeds in a secondary manner.

[0029] In this embodiment, as Figure 1 As shown, the sowing unit 3 (also known as the seed metering device) is connected to the discharge port of the anti-caking unit 2 and is used to sow corn seeds into the soil in sequence.

[0030] In specific implementation, a first anti-clumping mechanism 202 is installed in the anti-clumping unit 2 to disperse larger clumps of corn seeds, effectively preventing clumped seeds from being sown into the soil simultaneously. A second anti-clumping mechanism 203 is installed near the discharge port in the anti-clumping unit 2 to further disperse clumps of seeds missed by the first anti-clumping mechanism 202 or smaller clumps that have not been completely dispersed, further preventing clumped seeds from being sown into the soil simultaneously, thereby increasing corn yield.

[0031] In some embodiments of this application, such as Figure 2 As shown, the anti-clogging unit 2 also includes an anti-clogging drive unit 204 and an anti-clogging transmission unit 205.

[0032] In this embodiment, the anti-clogging drive unit 204 can be an electric motor structure, with the output shaft of the electric motor serving as the power output end. The power output end of the anti-clogging drive unit 204 and the power input end of the anti-clogging transmission unit 205 can be connected by a flange structure, enabling the anti-clogging drive unit 204 to drive the anti-clogging transmission unit 205 to rotate.

[0033] In this embodiment, as Figure 2 As shown, the first anti-clogging mechanism 202 includes several anti-clogging wings 2021. The anti-clogging wings 2021 are arranged along the circumference of the anti-clogging transmission part 205 and are fixedly connected to it. Specifically, there can be six anti-clogging wings 2021, arranged in two groups spaced vertically along the anti-clogging transmission part 205, with three wings 2021 in each group, evenly distributed along the circumference. The anti-clogging wings 2021 can be made of metal and are fixedly connected to the anti-clogging transmission part 205 by welding or threaded connections.

[0034] In this embodiment, the end face of the unbundling wing 2021 forms an angle with the axis of the anti-caking transmission part 205. That is, the unbundling wing 2021 is not arranged horizontally or vertically, but at an angle with the axis of the anti-caking transmission part 205. By setting the angle, the unbundling wing 2021 can be more effective in unbundling clumps of corn seeds.

[0035] In this embodiment, when the anti-clumping unit 2 is working, the anti-clumping drive unit 204 drives the anti-clumping transmission unit 205 to rotate, and the anti-clumping transmission unit 205 drives several unclogging wings 2021 to rotate inside the shell 201 of the anti-clumping unit 2, which can effectively unclump the corn seeds that have entered the anti-clumping unit 2.

[0036] In some embodiments, such as Figure 2 As shown, the second anti-clogging mechanism 203 is connected to the anti-clogging transmission part 205, and the connection method can be welding or threaded connection. The second anti-clogging mechanism 203 includes: a driving part 2031 and a driven part 2032 that mesh with each other, a support rod 2033, and a plurality of unclogging rods 2034.

[0037] The driving part 2031 can adopt a bevel gear structure and be mounted on the anti-clogging transmission part 205. The driven part 2032 can adopt two bevel gears that mesh with the driving part 2031 and are symmetrically arranged on both sides of the anti-clogging transmission part 205.

[0038] Furthermore, a housing 2035 is fitted over the active part 2031 and the driven part 2032 and fixedly connected to the active part. This housing provides support for the support rod and prevents corn seeds from entering the meshing position of the active part 2031 and the driven part 2032 and being crushed.

[0039] Furthermore, in this application, the support rods 2033 are arranged symmetrically as two support rods 2033. One end of each support rod 2033 is fixedly connected to two driven parts 2032 and rotates with the driven parts 2032. The other end of each support rod 2033 is connected to the housing 201 of the anti-clogging unit 2. This connection can be achieved by opening holes in the housing 201 and using bearings to support the other end of the support rod 2033 in the corresponding holes.

[0040] Furthermore, in this application, several loosening rods 2034 are symmetrically arranged on two support rods 2033 and can be fixedly connected by welding or other methods so that the loosening rods 2034 can rotate together with the support rods 2033. The number of loosening rods 2034 can be arranged in three groups at intervals on each support rod 2033, with each group consisting of three loosening rods 2034 evenly arranged in a circumferential direction. Other numbers of loosening rods 2034 and other arrangement methods can also be used.

[0041] In specific implementation, a second anti-clumping mechanism 203 is set at the discharge port of the anti-clumping unit 2, which can re-clump the corn seeds that were missed or not completely dispersed by the first anti-clumping mechanism 202, so as to obtain completely dispersed and independent corn seeds, providing favorable conditions for precise sowing.

[0042] In some embodiments of this application, such as Figure 2 As shown, the previous embodiment has been improved by setting the active part 2031 to be adjustable up and down by the anti-clogging transmission part 205.

[0043] Specifically, the lower end of the anti-clogging transmission part 205 has a threaded structure 2051, allowing the drive part 2031 to rotate on the thread, thereby adjusting its height. Furthermore, multiple positioning holes 206 are provided on the circumferential position of the upper end of the drive part 2031 and on one side of the anti-clogging transmission part 205. When the drive part 2031 is rotated and adjusted to a certain height, a positioning pin (not shown in the figure) is inserted into the positioning hole 206 where the drive part 2031 and the anti-clogging transmission part 205 are aligned, thus positioning the drive part 2031.

[0044] More specifically, to accommodate the height adjustment of the active unit 2031, the two holes in the housing 201 of the anti-clogging unit 2 can be configured as oblong holes 207. The two ends of the support rod 2033 extend into the corresponding two oblong holes 207, so that when the height of the active unit 2031 is adjusted, the support rod 2033 can move up and down with the active unit 2031 within the oblong holes 207.

[0045] In this embodiment, when the height of the second anti-clogging mechanism 203 needs to be adjusted, the housing 2035 is first opened, then the positioning pin is removed, and the active part 2031 is rotated so that the active part 2031 moves up and down in the threaded structure 2051 of the anti-clogging transmission part 205. At this time, the entire second anti-clogging mechanism 203 moves up and down together with the active part 2031, and one end of the support rod 2033 also moves in the elongated hole 207. When the height is adjusted to the required position, the active part 2031 is aligned with the positioning hole 206 of the anti-clogging transmission part 205, and the positioning pin is inserted into the positioning hole 206 to achieve positioning.

[0046] In specific implementation, the active part 2031 is configured with an adjustable height, allowing the height of the second anti-clumping mechanism 203 at the discharge port of the anti-clumping unit 2 to be adjusted as a whole. Since the space is smaller closer to the discharge port, it can further disperse smaller clumps of corn seeds. Especially when clumps of corn seeds are still observed after planting, the height of the second anti-clumping mechanism 203 can be lowered to disperse even smaller clumps of corn seeds.

[0047] In some embodiments, such as Figure 3 As shown, the sowing unit 3 includes a sowing drive unit 301 and a sowing transmission unit 302.

[0048] In this embodiment, the sowing drive unit 301 can be a motor, which is located at one end of the sowing unit 3. Specifically, it can be located outside the housing of the sowing unit 3, but the output shaft should be located inside the housing. The output shaft of the motor is the power output end, which is connected to the power input end of the sowing transmission unit 302 and drives the sowing transmission unit 302 to rotate.

[0049] In this embodiment, the sowing transmission unit 302 is used to transport corn seeds from the inlet of the sowing unit 3 to the outlet of the sowing unit 3. The sowing transmission unit 302 can adopt a drive shaft structure, with one end connected to the power output end of the sowing drive unit 301, for example, by a flange connection. The other end of the sowing transmission unit 302 can be supported by bearings to the housing.

[0050] In this embodiment, as Figure 3 As shown, a spiral fan blade 305 can also be provided on the sowing transmission unit 302, which can transport corn seeds from the feed port of the sowing unit 3 to the discharge port of the sowing unit 3 during rotation.

[0051] In practice, the sowing unit 3 uses the sowing drive unit 301 to drive the sowing transmission unit 302 to rotate, which can transport corn seeds from the inlet to the outlet of the sowing unit 3. During the transportation process, the corn seeds are gradually dispersed from a gathered state to a seed-by-seed state and finally sown into the soil, thereby achieving uniform and precise sowing of corn seeds.

[0052] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
