Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically a seed broadcasting machine for vegetable planting. Background Technology

[0002] Vegetable cultivation refers to the process by which people utilize natural conditions such as land, temperature, water, and sunlight to scientifically cultivate various edible vegetable crops through agricultural activities such as sowing, seedling raising, transplanting, fertilizing, watering, and pest and disease control, in order to obtain stable, high-yield, and high-quality vegetable products to meet the needs of daily life and market supply.

[0003] A search revealed a patent document with publication number CN211671288U, which discloses a seed spreader for agricultural planting. The document describes a process where "when it is necessary to spread crop seeds, the user first turns on the motor, then pours the seeds into the feed hopper. The seeds then enter the main body of the device. At this time, the motor rotates, driving a rotating rod to rotate. The rotating rod causes the baffles to rotate, and the seeds fall into the gaps between the different baffles. As the baffles rotate continuously, they cause the crop seeds to rotate. When the baffles rotate to a position opposite to the partitions inside the bottom box, the seeds between the baffles fall between the different partitions and finally fall through the bottom box, sowing them into the soil. This automatically completes the seed spreading work, improving work efficiency." Based on the search of the aforementioned patents and in conjunction with existing seed broadcasters, it was found that in current vegetable planting operations, the seed broadcasting process generally suffers from problems such as uneven seeding, inconsistent seed depth, and unstable soil compaction. Traditional manual sowing methods are extremely inefficient and heavily influenced by operator experience, easily leading to irregular seed spacing and uneven subsequent plant growth density, thus affecting yield and quality. While some mechanical sowing equipment can achieve a certain degree of automation, its seeding structure is simple and cannot accurately control the sowing depth and soil covering thickness according to soil conditions. At the same time, seeds are prone to jumping or being missed during the sowing process, affecting the uniformity of seedling emergence. Based on this, this utility model designs a seed broadcaster for vegetable planting to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-10 In this embodiment of the utility model, a seed spreader for vegetable planting includes a drive compartment 1. A drive track 2 is installed at the lower end of the drive compartment 1 to enable the whole machine to move smoothly and forward on the surface of the cultivated land. A soil spreading mechanism 5 and a seed laying mechanism 3 are arranged in sequence on the right side of the drive compartment 1. A grooving mechanism 4 is arranged below the seed laying mechanism 3. The three are arranged in sequence according to the operation order to form a continuous automatic operation process of "grooving, seeding, and covering with soil".

[0032] The seeding mechanism 3 is installed in the middle right side of the drive unit compartment 1, and includes a support frame 301, a mounting frame 302, a feeding funnel 303, a discharge pipe 304, an electric control valve 305, a valve body bracket 306, a mounting frame 307, and a transmission track 308. The support frame 301 is fixedly installed at the right end of the drive unit compartment 1, serving as the main load-bearing structure of the entire seeding mechanism 3. The mounting frame 302 is fixedly installed in the middle of the support frame 301 and is used to install the feeding funnel 303. The feeding funnel 303 is fixedly located in the middle of the mounting frame 302, and its interior is used to centrally store the seeds to be sown. The bottom end of the feeding funnel 303 is connected to the discharge pipe 304 for discharging. An electric control valve 305 is installed on the pipeline 304 to control the seed falling speed and the placement interval. The electric control valve 305 is fixed to the support frame 301 by the valve body bracket 306 to keep the electric control valve 305 in a stable installation state and avoid vibration causing a decrease in control accuracy. The mounting bracket 307 is fixedly installed at the lower end of the storage box 401 for mounting the transmission track 308. The transmission track 308 moves synchronously with the drive machine compartment 1 during operation, and achieves continuous sowing in coordination with the feeding rhythm. Through the opening and closing of the electric control valve 305 and the synchronous cooperation of the transmission track 308, the seeds can fall quantitatively, at a constant speed and rhythmically into the groove formed by the grooving mechanism 4, thereby realizing the sowing.

[0033] The grooving mechanism 4 is installed below the planting mechanism 3 and includes a power storage box 401, a bearing seat 402, a rotating rod 403, a mounting sleeve 404, a cutting rod 405, a transmission gear 406, a drive gear 407, a gear cover 408, and a drive motor 409. The power storage box 401 is fixed to the right end of the support frame 301 and provides power to the drive motor 409. The drive motor 409 is installed on the right side of the power storage box 401 and drives the transmission gear 406 to rotate through the drive gear 407. The transmission gear 406 is fixedly installed on the outer wall of the rotating rod 403. The rotating rod 403 is rotatably connected to the mounting frame 307 through the bearing seat 402, so that the rotating rod 403... The rotating rod 403 is able to rotate stably under the support of the bearing. The middle part of the rotating rod 403 is fixedly connected to the mounting sleeve 404. The outer wall of the mounting sleeve 404 is fixed with a digging rod 405. The digging rod 405 rotates continuously under the drive of the rotating rod 403, thereby performing digging and grooving operations on the ground surface to form uniform trenches. The gear cover 408 is installed on the outside of the transmission gear 406 and the drive gear 407 to prevent mud and sand from entering the gear set and to ensure the stability and service life of the gear transmission system. The grooving mechanism 4, through the synergistic effect of motor drive and gear transmission, enables the digging rod 405 to efficiently complete the grooving operation, providing an ideal sowing trench for the subsequent seeding mechanism 3.

[0034] The soil-laying mechanism 5 is installed on the right side of the drive unit 1 and the right side of the seeding mechanism 3. It includes a first support 501, a second support 502, an adjusting screw 503, a rotating sleeve 504, a bulldozer plate 505, and a telescopic rod 506. The first support 501 and the second support 502 are both fixed to the outer wall of the support frame 301, forming a stable connection foundation. The adjusting screw 503 is threadedly connected to the middle of the second support 502. The lower end of the adjusting screw 503 is connected to the rotating sleeve 504, and the lower end of the rotating sleeve 504 is fixedly installed with the bulldozer plate 505. A telescopic rod 506 is fixedly installed on the right end of 05. The telescopic rod 506 is located between the first support 501 and the bulldozer plate 505. The adjusting screw 503 can be rotated to adjust the height of the bulldozer plate 505. The telescopic rod 506 further stabilizes the posture of the bulldozer plate 505 through its telescopic movement, so that the bulldozer plate 505 maintains a suitable angle with the ground during operation, thereby achieving uniform soil covering. When the seeds are sown into the trench, the bulldozer plate 505 pushes the soil back into the trench as the equipment moves forward, realizing the soil covering operation of the seeds and ensuring that the seeds are evenly covered.

[0035] During operation, the drive unit 1 moves the entire machine along the ground surface. The trenching mechanism 4 operates first, and the digging rod 405 rotates at high speed to form continuous trenches. Then, the seeding mechanism 3, through the cooperation of the electric control valve 305 and the feeding pipe 304, quantitatively drops the seeds into the trenches. Finally, the soil spreading mechanism 5 backfills the trenches and levels the ground surface through the pushing action of the bulldozer plate 505, thus completing the entire automated seeding operation process.

[0036] The seeding mechanism 3, through the coordinated design of the injection funnel 303 and the electric control valve 305, realizes quantitative and constant-speed seed delivery. Combined with the synchronous drive of the transmission track 308, it can ensure accurate seed landing point and uniform spacing, effectively improving sowing accuracy and germination consistency.

[0037] The trenching mechanism 4 uses a power system consisting of a power storage box 401 and a drive motor 409. Through gear transmission, it drives the rotating rod 403 and the digging rod 405 to rotate continuously, achieving a stable trenching effect. The trenches are formed evenly and the operation is efficient. The gear cover 408 provides good protection and ensures the long-term stable operation of the transmission system.

[0038] The soil-laying mechanism 5, through the coordination of the adjusting screw 503 and the telescopic rod 506, enables flexible adjustment of the angle and height of the bulldozer 505, which can achieve uniform soil covering according to different ground conditions, maintain consistent soil layer thickness, and further improve moisture retention and seedling survival rate after sowing.

[0039] In summary, the seeding mechanism 3, the trenching mechanism 4, and the soil-laying mechanism 5 cooperate with each other, and through the coordinated operation of the electronic control system and mechanical transmission, they form a continuous, stable, and efficient "trenching, seeding, and soil-laying" operation process. This achieves full automation and high precision in the vegetable planting and sowing process, significantly improving the level of agricultural mechanization and production efficiency.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
