Description

Technical Field

[0001] This application relates to the technical field of fertilizing equipment, and particularly to a bilateral synchronous profiling fertilizing device for a corn pyramid-shaped double-plant close-planting seeder. Background Art

[0002] The pyramid-shaped double-plant close-planting technology arranges the adjacent three sowing units in adjacent two rows in a pyramid shape through a specific sowing mode. This arrangement can make more reasonable use of land resources, increase the number of corn plants per unit area, and thus improve the yield. The bilateral synchronous profiling fertilizing device usually has an independent fertilizer tank and a double-fertilizer hopper design, which can accurately control the fertilization amount. The fertilizer tank is made of materials resistant to weathering and corrosion to ensure the durability and stability of the fertilizing device.

[0003] After retrieval, the publication number: CN221768700U discloses a self-synchronous pyramid-shaped seeder, and the rear soil covering device is arranged behind the seed dropping position of the seed dropping box to cover the soil after sowing. In order to improve the soil covering effect, the first soil covering wheel and the second soil covering wheel are inclined along the vertical direction of the seeder. Specifically, the sides of the first soil covering wheel and the second soil covering wheel close to the bottom surface are close to each other, so that the first soil covering wheel and the second soil covering wheel are inclined at a certain angle relative to the vertical direction. The specific setting of this angle can be selected by the staff according to the actual situation. A rear mud scraper is also arranged in the rear soil covering device, and the rear mud scraper is located behind the first soil covering wheel and the second soil covering wheel and is used to scrape off the soil adhered to the first soil covering wheel and the second soil covering wheel.

[0004] Regarding the above related technologies, the inventor believes that there are the following technical defects to be improved: The profiling wheels and the furrow openers on both sides of this device are not arranged in the same position, so the consistency of the sowing depth cannot be ensured, and the position of the soil scraper of this device is fixed, and its adjustability is general, resulting in the risk of waste scattering.

[0042] Several sets of damping rods 65 are provided, and the sets of damping rods 65 are arranged at equal intervals on the inner side of the parallel connecting rod bracket 2.

[0043] The usage process of the dual-side synchronous contour-following fertilization device of the corn triangular double-plant dense planting seeder in this application embodiment is roughly as follows:

[0044] First, the required fertilizer is loaded into the top fertilizer tank 1. The top fertilizer tank 1 is designed with sufficient capacity to ensure an adequate supply of fertilizer during continuous operation. The position and angle of the adjustable scraper assembly 7 are adjusted according to operational needs. By rotating the circular knob 74, the convex tooth 75 engages with the gear disc 76, thereby adjusting the height and tilt angle of the scraper blade 72 to ensure consistent fertilization depth. Simultaneously, the working condition of the feeding assembly 5 and the furrowing assembly 6 is checked and confirmed. The seeder is then started, and the equipment begins operation. Under gravity, the fertilizer in the top fertilizer tank 1 flows into the fertilizer cylinder 3 through the metal connecting pipe 4. The design of the fertilizer cylinder 3 allows the fertilizer to be evenly distributed into the multiple feeding assemblies 5. The conical feeding cylinders 54 of the feeding assembly 5 are symmetrically arranged to ensure that the fertilizer is accurately and evenly applied to the sides and middle of the seed furrow. The soil-covering disc 62 of the furrowing assembly 6 cuts into the soil during its movement, forming the seed furrow. Simultaneously, the conical feeding cylinder 54 of the feeding assembly 5 applies fertilizer into the seed furrow, achieving simultaneous furrowing and fertilization. The scraper blade 72 of the adjustable scraper assembly 7 is connected to the guide plate 71 via the connecting shaft 73, allowing its position and angle to be adjusted as needed. Following the furrowing assembly 6, the scraper blade 72 covers the applied fertilizer and seeds with soil and smooths the soil surface. The design of the circular knob 74 and the leaf spring 8 allows the scraper blade 72 to be fixed in position, ensuring consistent fertilization depth. The damping rod 65 and compression spring 66 of the furrowing assembly 6 work together to reduce the vibration amplitude of the covering disc 62 during soil cutting, improving equipment stability and operational efficiency.

[0045] The beneficial technical effects of the dual-side synchronous contour-following fertilization device of the corn triangular double-plant dense planting seeder of this application embodiment are roughly as follows:

[0046] By designing the adjustable scraper assembly 7 to be positioned co-located on both sides of the furrowing assembly 6, the problem of inconsistent sowing depth caused by the misalignment of the contour wheel and furrow opener is effectively solved. This co-location ensures uniform soil treatment during fertilization and sowing, thereby improving crop growth consistency and yield. Furthermore, the adjustable scraper assembly 7 is adjustable, allowing for adjustments to the scraping depth and angle according to actual needs, effectively addressing variations in soil type and moisture. This design reduces the risk of waste scattering, improves the accuracy and efficiency of soil treatment, and the entire device has a compact structure and high functional integration.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
