Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting equipment, and in particular relates to a sliding adjustable plant spacing planter for corn and beans. Background Technology

[0002] With the advancement of science and technology, people have gained a better understanding of the living habits of plants. Intercropping, for example, fully utilizes the differences between two plants in terms of plant shape, light requirements, and nutrient utilization to achieve complementary symbiosis and increase yield and efficiency.

[0003] Currently, the most common intercropping crops in my country are legumes and corn. Intercropping corn and legumes can effectively achieve complementary resource utilization. For example, corn plants are tall (tall stalks), while soybean plants are short (dwarf stalks), forming a "tall-low" combination. Corn utilizes the upper layer of sunlight, while soybeans utilize the lower layer of diffused light, improving light energy utilization. Soybean rhizobia can fix nitrogen from the air (50-100 kg of nitrogen per hectare), which, in addition to its own use, can also provide some nitrogen for corn. Corn has a high demand for phosphorus and potassium, while soybeans have a strong ability to absorb phosphorus. The combination of the two can reduce the amount of chemical fertilizer (especially nitrogen fertilizer). The alternation of tall and short stalk crops reduces field canopy closure, improves ventilation, and reduces the risk of pests and diseases.

[0004] Intercropping of corn and legumes has been promoted from experimental fields to large fields. However, existing seeders are mainly designed for sowing single crops. Intercropping requires sowing twice, and the spacing between seeds is difficult to adjust, making it impossible to make appropriate adjustments according to the planting environment.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-4 As shown, this embodiment aims to achieve one-time sowing of corn and bean plants with adjustable spacing between them. To achieve this objective, this embodiment provides a sliding adjustable corn and bean plant spacing planter, including a frame 1 and a seed box 2 mounted on the frame 1. In this embodiment, a hand-push type planter is used as an example. The frame 1 is designed to meet the hand-push type. If a mechanical traction type is used, the style of the frame 1 can be changed. The seed box 2 is the same as the existing seed box 2, both being rectangular in shape. However, unlike the existing horizontal placement, in this embodiment, it is placed in a front-to-back configuration, that is, its long side is the direction of travel of the planter.

[0025] Front wheels 11 and rear wheels 14 are respectively provided at the front and rear ends of the frame 1. Both front wheels 11 and rear wheels 14 are rotatably mounted on the frame 1. The seed box 2 is located between the front wheels 11 and rear wheels 14. A lower seed hopper 6 is provided at the bottom of the seed box 2, and the seed box 2 and the lower seed hopper 6 are connected. The above structure is a common existing structure, with only the angle of the seed box 2 changing. Therefore, it will not be described in detail in this embodiment.

[0026] Considering the need to simultaneously sow corn and beans, it is necessary to place both corn and beans in the seed box 2. Therefore, in this embodiment, a partition 21 is provided in the seed box 2. The partition 21 is arranged at intervals in the seed box 2, dividing the seed box 2 into several seed chambers arranged in the front and back. Since this embodiment needs to accommodate the planting of corn and beans, the number of seed chambers should be even.

[0027] Considering that the number of seeds that can be placed at each location is limited during sowing, a seed core 3 is provided below the seed cavity. The seed core 3 is columnar and is rotatably positioned inside the seed box 2. Specifically, the axis of the seed core 3 is set along the direction from the front traveling wheel 11 to the rear traveling wheel 14. In this embodiment, the entire seed box 2 shares one seed core 3.

[0028] To facilitate sowing, sowing holes 31 are spaced apart on the side wall of the sowing core 3. These sowing holes 31 are blind holes and are evenly distributed in a ring on the side wall of the sowing core 3. It should be noted that a set of ring-shaped sowing holes 31 is provided below each seed cavity. Simultaneously, a discharge trough (not shown in the figure) is provided at the bottom of the seed box 2. Considering the movable nature of the seed hopper 6, a discharge trough nearly the length of the seed box 2 is provided at the bottom of the entire seed box 2 to meet the material discharge requirements.

[0029] The seed hopper 6 is slidably positioned below the discharge trough. Specifically, a sliding groove (not shown in the figure) is provided at the bottom of the seed box 2. The sliding groove consists of two L-shaped plates fixed at intervals at the bottom of the seed box 2. The sliding groove is located on both sides of the discharge trough. A fixing bolt 61 is provided in the sliding groove. The fixing bolt 61 is slidably positioned in the sliding groove, that is, the head of the bolt is between the two L-shaped plates, and its screw part passes through the space between the two L-shaped plates. The seed hopper 6 is movably fixed below the discharge trough by the cooperation of the fixing bolt 61 and the nut.

[0030] Considering that current sowing methods involve planting in succession, which can lead to repeated sowing in the same area, a rotating shaft 32 is fitted into the middle of the sowing core 3 to avoid this problem. One end of the rotating shaft 32 extends out of the seed box 2. In this embodiment, the end of the rotating shaft 32 extending out of the seed box 2 is the front end, and an intermittent transmission device is connected to the end of the rotating shaft 32 extending out of the seed box 2. The main function of the intermittent transmission device is to ensure that the sowing core 3 rotates one sowing hole 31 distance for the entire sowing box 2 to move a certain distance.

[0031] The intermittent transmission device can be directly controlled by a motor. In this embodiment, considering that the travel distance of the seeder is actually related to the front traveling wheel 11 and the rear traveling wheel 14, the intermittent transmission device includes a drive disc 33 mounted on a rotating shaft 32. The drive disc 33 is disc-shaped, and drive rods 34 are spaced apart on the circumference of the drive disc 33. A drive shaft 13 is mounted on the frame 1 and is rotatably mounted on the frame 1. A drive column 8 is mounted on the drive shaft 13. A drive protrusion 81 is provided on the side wall of the drive column 8. The drive protrusion 81 is spirally arranged on the side wall of the drive column 8. One end of the drive protrusion 81 is located between two adjacent drive rods 34. When the drive shaft 13 rotates, it drives the drive column 8 to rotate, thereby driving the drive protrusion 81 to rotate. Since one end of the drive protrusion 81 is located between two drive rods 34 and the drive protrusion 81 is spirally arranged, the rotation of the drive protrusion 81 will drive the drive rods 34 to move, thereby realizing the slow rotation of the drive disk 33, and thus realizing intermittent sowing.

[0032] To further coordinate with the traveling wheels, a rotating shaft 12 is mounted on the front traveling wheel 11. The front traveling wheel 11 is rotatably mounted on the frame 1 via the rotating shaft 32. A drive gear (not shown in the figure) is also mounted on the rotating shaft 12. The drive gear is located on one side of the front traveling wheel 11. An auxiliary gear (not shown in the figure) is also mounted on the drive shaft 13. The drive gear and the auxiliary gear are connected by a chain.

[0033] In this way, no additional power is needed to ensure that the sowing is not repeated.

[0034] To prevent seeds from falling directly from the discharge trough due to large spacing adjustments, several guide plates 7 are installed between adjacent seed hoppers 6. The guide plates 7 can be fixed to the bottom of the discharge trough using bolts 61, or they can be installed by inserting into sliding grooves. In this embodiment, for ease of installation, an insert method is used. The guide plates 7 are approximately 2 cm wide. Thus, the combination of multiple guide plates 7 seals the discharge trough between the two seed hoppers 6, ensuring proper sowing.

[0035] To ensure effective seed entry into the sowing hole 31, a sowing brush 4 is installed inside the seed box 2. The sowing brush 4 is cylindrical in shape, with left and right brushes or bristles on its side walls. Its purpose is to move the seeds inside the seed box 2, ensuring they are planted into the sowing hole 31. For this purpose, the sowing brush 4 is rotatably mounted on one side of the sowing core 3, and the distance between the sowing brush 4 and the sowing core 3 is smaller than the size of the seed to be sown. Meanwhile, to avoid the need for additional drive equipment, a sowing shaft 41 is mounted on the sowing brush 4, extending out of the seed box 2. A sowing brush gear 42 is mounted on one end of the sowing shaft 41 extending out of the seed box 2. A sowing gear 35 is also mounted on the rotating shaft 32, and the sowing gear 35 and the sowing brush gear 42 are connected by a chain.

[0036] Considering that soil covering is also required, a soil covering tray 5 is also installed on the frame 1, which is located behind the seed box 2.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
